Manufacturing method of paper feeding mechanism of folding and gluing machine

The application of folding and gluing machine is a process of packaging box processing. It is a machine that folds the printed and die-cut paperboard and sticks it to life. At present, the folding and gluing machine is basically composed of six parts: paper feeding, pre folding, gluing, folding, pressure pop-up and compaction collection. The power of the whole machine is provided by a rectifier stepless speed change motor, and some are driven by multiple speed regulating motors. Compared with the traditional manual folding and gluing machine, the folding and gluing machine has the characteristics of smooth speed regulation, simple operation, straight box folding, reliable pasting, sanitation and efficiency, stable quality, strong universality and wide application range. It can realize the automatic operation of the box making industry by matching with printing machines, die-cutting machines and other machines. At present, the paper feeding mechanism of folding and gluing machine on the market adopts belt rotation friction paper feeding, and the paperboard is stacked obliquely on the rubber belt. When the belt rotates, a paperboard under the paper pile is transported forward under the action of friction. If the paperboard is too light and the operator does not add the paperboard in time, the height of the paper stack is not enough, and too much paper powder is accumulated on the surface, resulting in belt slip and insufficient friction between the paperboard and the belt. It is easy to lead to empty tension, which often occurs in the process of paperboard conveying.

Technical realization elements

In view of the shortcomings of the prior art, the utility model aims to provide a paper feeding mechanism of a folding and gluing machine with reasonable structural design, so as to solve the problems raised in the above background technology.

In order to achieve the above purpose, the utility model provides the following technical solutions.

The utility model relates to a paper feeding mechanism of a folding and gluing machine, which is characterized in that it comprises a conveyor belt, a storage box, a feeding carton and a dust collecting box, the storage box, the feeding carton and the dust collecting box are all located above the conveyor belt.The storage box is located at the left end of the feeding carton. The dust collecting box is located at the left end of the storage box, and the feeding carton comprises a front baffle . The upper end of the front baffle is provided with a buzzer. The inner wall of the front baffle is provided with an infrared transmitter. The inner wall of the rear baffle is provided with an infrared receiver. The position of the infrared transmitter corresponds to the position of the infrared receiver, and the infrared receiver is connected with the buzzer through a signal line. The bottom end of the storage box is provided with a vibrating plate. The left end of the storage box is provided with a plurality of dust suction holes.The interior of the plurality of dust suction holes are provided with fans, and the plurality of dust suction holes are connected with the dust collection box.

By adopting the above technical scheme, first put the paperboard into the storage box. The paperboard is located on the vibrating plate. Start the vibrating plate. The shaking of the vibrating plate can shake off the paper powder carried by the paperboard. At the same time, the fan inside the dust suction hole operates to suck the shaken paper powder into the dust collection box. After the treatment is completed, turning off the fan and vibrating plate, taking out a certain amount of paperboard and place it in the feeding box, and shaking off the paper powder carried by the paperboard before the paperboard enters the feeding carton to prevent the paper powder from accumulating on the conveyor belt and avoid empty sheets caused by slippage of the conveyor belt. At the same time, when the cardboard enters the carton, the height of the paper stack is higher than that of the infrared transmitter and infrared receiver. Start the conveyor belt, infrared transmitter and infrared receiver. The infrared emitted by the infrared transmitter is blocked by the paper stack and cannot be accepted by the infrared receiver. The conveyor belt uses friction drive to separate the cardboard one by one, transferring to the next mechanism. At this time, the height of the paper stack in the carton gradually decreases. When the height of the paper stack is less than the height of the infrared transmitter and the infrared receiver, the infrared emitted by the infrared transmitter is accepted by the infrared receiver, and the infrared receiver sends a signal to control the buzzer to sound to remind the operator to add cardboard in time to prevent the height of the paper stack from being insufficient. The paper pile is too light to avoid empty tension caused by insufficient friction between paperboard and belt.

Preferably, the dust collecting box and the storage box are detachably connected.

By adopting the above technical scheme, the paper powder in the dust collection box needs to be treated after the device is used for a period of time, and the detachable design facilitates the dust treatment.

Preferably, the buzzer is provided with a red LED lamp.

By adopting the above technical scheme, due to the noisy environment of the factory, in order to avoid the workers from hearing the buzzer sound due to external interference, a red LED light is set on the buzzer. When the buzzer rings, the red LED light will also light up to remind the workers visually. At the same time, the red LED lamp is more eye-catching than other colors.

Preferably, the surface of the conveyor belt is roughened.

By adopting the above technical scheme, the surface roughness of the conveyor belt is increased, the friction between the paperboard and the conveyor belt is improved, and the occurrence of empty tension is further prevented.

Preferably, the upper end of the storage box is provided with a box cover.

By adopting the above technical scheme, when the vibrating disk is operated, the storage box is covered with a box cover to prevent the paper powder from escaping from the upper port of the storage box, polluting the air and causing harm to human body.

Preferably, a plurality of the dust suction holes are evenly distributed.

By adopting the above technical scheme, it can ensure that all paper powder is sucked into the dust collection box, avoiding remaining paper powder in the storage box, and improving the working efficiency of the dust collection hole.

Advantages of the utility model

1. The vibrating disk shall be set to prevent the paper powder from accumulating on the conveyor belt and avoid the empty sheet phenomenon caused by the slip of the conveyor belt.

2. The setting of infrared transmitter, infrared receiver and buzzer reminds the operator to add paperboard in time, so as to prevent the height of paper pile from being insufficient, the paper pile from being too light, and the empty phenomenon caused by insufficient friction between paperboard and belt.

3. The dust collecting box and the storage box are detachably connected to facilitate the treatment of dust.

4. A red LED light is set on the buzzer to remind the staff visually. At the same time, the red LED light is more eye-catching than other colors.

5. The surface of the conveyor belt is roughened, which increases the surface roughness of the conveyor belt, improves the friction between the paperboard and the conveyor belt, and further prevents the occurrence of empty tension.

6. The upper end of the storage box is provided with a box cover to prevent paper powder from escaping from the upper port of the storage box, polluting the air and causing harm to human body.

7. Several dust collection holes are evenly distributed, which can ensure that all paper powder is sucked into the dust collection box, avoid remaining paper powder in the storage box, and improve the working efficiency of the dust collection holes.
