Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of paper plate forming machines, and particularly relates to a paper plate forming machine feeding device. BACKGROUND

[0002] Paper plates are made of chemical wood pulp and are tools with the same shape as other porcelain plates, but are much lighter. Paper plates can be used to hold food, and can also be used to hold bread, cakes, snacks and the like, and are increasingly loved by people and gradually become indispensable dining tools in people's homes.

[0003] However, the traditional paper plate forming machine often needs manual feeding during manufacturing, which is very troublesome to operate, and one careless move can easily touch the machine, causing harm to the operator. Moreover, manual feeding is unstable and has low production efficiency. SUMMARY

[0004] The application provides a paper plate forming machine feeding device to solve the technical problem that manual feeding is easy to cause harm to the operator.

[0005] The technical scheme adopted by the application is as follows:

[0006] A paper plate forming machine feeding device comprises a mounting frame, the mounting frame is connected to a support frame on the left and right and arranged along the same horizontal line, the upper end surface of the mounting frame is a feeding end surface, two groups of gear and rack assemblies are arranged inside and above the mounting frame, the lower gear and rack assembly is connected to a crank rocker device, the upper gear and rack assembly is fixedly connected to a correction plate, a driving device is arranged at the middle position of the support frame, the driving device is connected to a feeding plate, the correction plate and the feeding plate are on the same horizontal line as the feeding end surface, and a feeding roller and a limiting roller are arranged in parallel above and below the feeding end surface on the side of the support frame away from the feeding plate.

[0007] By using the combination of the gear and rack assembly, the crank rocker device and the correction plate, the control system in the feeding process is simplified, the use of complex electrical control and valve components is avoided, the equipment downtime caused by electrical faults is reduced, the wear and maintenance problems of the valve system are avoided, the gear and rack assembly cooperates with the crank rocker device and the correction plate to realize precise control, ensures the accurate positioning and uniform movement of the raw materials placed on the feeding plane during feeding, and avoids deviation in the feeding process.

[0008] Optionally, a feeding groove is arranged at one end of the mounting frame facing the feeding plate, a transmission rod is arranged below the feeding plate, one end of the transmission rod is rotatably connected to the feeding plate, the opposite end is rotatably connected to a fixed block, and a driven wheel is arranged on the side wall of the transmission rod.

[0009] By adopting the above technical solution, the design of the feeding groove enables the feeding plate to slide smoothly on the mounting frame, avoiding the problem of material jamming caused by direct friction.

[0010] Optionally, the driving device includes a pulley and a cam, the pulley and the cam are coaxially installed, the cam is engaged with the driven wheel for transmission, and the pulley and the pulley located at one end of the feed roller are driven by a belt.

[0011] By adopting the above technical solution, the pulley is installed coaxially with the cam and drives the feed roller through the belt drive system, which can efficiently transmit power and reduce energy loss in the mechanical transmission process. The belt drive design can maintain a more stable operating state than the traditional gear system and has better performance in terms of noise and friction. The cooperation between the belt and the pulley can effectively disperse the load and reduce excessive wear, thereby extending the service life of various components of the system and reducing the maintenance and replacement costs in long-term operation. The cam and the driven wheel are driven by meshing transmission to drive the feed plate to achieve precise reciprocating motion. By adjusting the shape and speed of the cam, the forward and backward movement of the feed plate can be accurately controlled to ensure accuracy and stability during the feeding process.

[0012] Optionally, a spring is provided between the feeding plate and the support frame, one end of the spring is fixedly connected to the side wall of the feeding plate, and the other end is fixedly connected to the bottom of the support frame.

[0013] By adopting the above technical solution, the role of the spring between the feed plate and the support frame is to provide rebound force for the feed plate, ensuring that the feed plate can return to its original position after being driven by the cam and the driven wheel. The spring can effectively reduce the vibration or impact of the feed plate during operation and improve the stability of the device. This design can reduce the deviation of the feed plate caused by vibration during the feeding process through the rebound effect of the spring, thereby ensuring the accuracy of the feeding process.

[0014] Optionally, an adjustment block is provided on the side wall of the support frame, the adjustment block is fixedly connected to the telescopic rod below, a spring is provided on the upper end of the adjustment block, and the limiting roller is connected to the adjustment block through a rotating shaft.

[0015] By adopting the above technical solution, the design of the adjustment block and the telescopic rod can adjust the height of the feeding device according to production needs, adapt to the conveying requirements of different materials, improve the applicability of the feeding device in various working environments, and avoid the trouble of frequent equipment replacement or production line modification. The limit roller is connected to the adjustment block and fixed by a rotating shaft, which can accurately control the operating range of the feeding plate, avoid overflow or dislocation of materials during feeding, and ensure the continuity and stability of the production process.

[0016] Optionally, the support frame is a structure of two symmetrically arranged L-shaped plates, and the upper end surfaces of the L-shaped plates are fixedly connected to the lower end surface of the mounting frame.

[0017] By adopting the above technical solution, the L-shaped plate structure as a support frame provides good balance and stability through symmetrical arrangement, can withstand greater mechanical loads, and avoid structural offset or deformation under high-speed operation or high load. The symmetrical design of the L-shaped plate structure enables the feeding device to withstand greater physical impact and pressure, reducing failures caused by structural instability.

[0035] Working principle:

[0036] During operation, after the motor is started, the crank 5 rocker 6 assembly begins to rotate, and is converted into reciprocating motion through the gear 3 rack 4 below. This reciprocating motion drives the gear rack assembly above, so that the correction plate 7 is displaced in a direction perpendicular to the feeding plane. The correction plate 7 contacts the material to correct the position of the material. At the same time, another motor is started to drive the cam 82 and the pulley 81. The cam 82 engages with the driven wheel 14 on the transmission rod 12, thereby causing the transmission rod 12 to rotate back and forth, and then causing the feeding plate 9 to reciprocate in a direction horizontal to the feeding plane. When the pulley 81 is driven to rotate by the motor, the small pulley 81 is driven to rotate together by the action of the belt. The small pulley 81 is coaxially connected to the feed roller 10. The feed roller 10 starts to rotate, pushing the material for unloading operation.
