Description

Technical Field

[0001] This utility model relates to a conveyor mechanism with a toothed conveyor chain. Background Technology

[0002] A toothed chain, also known as a conveyor chain with pointed teeth, is commonly used in leather forming equipment. It transports leather by having the pointed teeth pierce the edges of the leather. There are two methods for transporting leather using a toothed chain: the first is where the conveyor chain supports the leather from below, as disclosed in patent document CN104828472A; the second is where the leather hangs from the conveyor chain, as disclosed in patent document CN106429207A. In the method where the conveyor chain supports the leather from below, the pointed teeth of the chain face upwards. When the edge of the leather is pierced by the pointed teeth and transported, the weight of the leather pulls on the conveyor chain, making it easy for the edge of the leather to detach from the pointed teeth. Summary of the Invention

[0003] The problem this invention aims to solve is the issue of sheet material falling off during transport in a toothed chain conveyor mechanism with upward-pointing teeth.

[0004] To solve the above problems, the present invention adopts the following solution:

[0005] According to this utility model, a toothed chain transmission mechanism with pressure rollers includes a conveying frame and chain frames disposed on both sides of the conveying frame. A toothed chain is disposed on the chain frames, and the chain frames include chain supports for supporting the toothed chain between sprockets. A pressure roller mechanism is disposed on the chain supports. The pressure roller mechanism includes a pressure frame and a plurality of pressure rollers disposed on the pressure frame. The pressure frame is disposed on the chain supports and parallel to the chain supports. The pressure rollers are spaced apart along the moving direction of the toothed chain. A ring-shaped toothed groove is provided circumferentially on the surface of each pressure roller. The teeth of the toothed chain on the chain supports can be positioned within the toothed grooves of the pressure rollers when the toothed chain moves.

[0006] Furthermore, the interval between adjacent pressing rollers on the pressing frame shall not exceed 30cm.

[0007] Furthermore, the pressure frame is mounted on the chain bracket via a spring guide post mechanism; the spring guide post mechanism includes a mounting bracket fixed to the chain bracket, a guide post and a spring connecting the mounting bracket to the pressure frame; the guide post is vertically arranged and movably connected to the pressure frame, allowing the pressure frame to rise and fall under the limiting and guiding influence of the guide post; the spring is vertically arranged and provides downward elastic force to the pressure frame.

[0008] Furthermore, the surface of the pressure wheel is made of an elastic material.

[0009] The technical effects of this utility model are as follows: This utility model uses a pressure wheel to lock the sheet material conveyed on the toothed chain, preventing the sheet material from falling off due to gravity. Through the elastic material of the spring and the pressure wheel, the friction caused by locking can be reduced by the frictional rolling of the pressure wheel when locking the sheet material.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Figure 2 An example of a toothed chain conveyor with a pressure roller is provided, comprising a conveyor frame and chain frames 100 disposed on both sides of the conveyor frame. Toothed chains are mounted on the chain frames 100. (See reference...) Figure 3 and Figure 4 The chain frame 100 includes a chain bracket 11 for supporting the toothed chain between sprockets. A pressure roller mechanism 2 is provided on the chain bracket 11. The pressure roller mechanism 2 is used to clamp the sheet material when it is carried and transported by the toothed chain. (Refer to...) Figure 1 and Figure 4The system includes a pressure frame 21 mounted on and parallel to the chain bracket 11, and pressure wheels 22 mounted on the pressure frame 21. Several pressure wheels 22 are mounted on the pressure frame 21, typically arranged at equal intervals, with a spacing generally not exceeding 30 cm. Each pressure wheel 22 is a roller with toothed grooves 221 on its surface, and the roller shaft is horizontal. The toothed grooves 221 are arranged circumferentially around the surface of the pressure wheel 22. The teeth 121 of the toothed chain 12 on the chain bracket 11 are located within the toothed grooves 221 of the pressure wheels 22 when the toothed chain moves. In other words, the toothed grooves 221 of the pressure wheels 22 arranged on the pressure frame 21 form a toothed channel for the teeth 121 of the toothed chain 12 to travel through. The teeth 121 of the toothed chain 12 are located within this toothed channel. The surface of the pressure wheels 22 is typically made of an elastic material. The elastic material can be, for example, natural rubber, silicone rubber, TPE, or PU. The elastic material on the surface of the pressure roller 22 provides a large frictional force when it comes into contact with the sheet material, thereby enabling the pressure roller 22 to roll as the sheet material moves.

[0019] Furthermore, in this embodiment, the pressure frame 21 is mounted on the chain bracket 11 via a spring guide post mechanism 23. There are at least two spring guide post mechanisms 23 that mount the pressure frame 21. (Refer to...) Figure 1 The spring guide post mechanism 23 includes a mounting frame 239, a guide post 231, and a spring 232. The mounting frame 239 includes a horizontal frame plate 2391 and a vertical frame plate 2392. The horizontal frame plate 2391 and the vertical frame plate 2392 are integrally connected to form an L-shaped structure. The vertical frame plate 2392 is vertically positioned and fixed to the chain bracket 11 by bolts. With the vertical frame plate 2392 and the chain bracket 11 fixed, the horizontal frame plate 2391 is horizontally positioned above the chain bracket 11. The guide post 231 is vertically positioned below the horizontal frame plate 2391 and is movably connected to the pressure frame 21, allowing the pressure frame 21 to rise and fall under the limiting and guiding influence of the guide post 231. In simple terms, the pressure frame 21 is equipped with a guide hole for the guide post 231 to pass through; the guide hole of the pressure frame 21 fits onto the guide post 231, allowing the guide post 231 to slide relative to the guide hole. In this embodiment, the horizontal frame plate 2391 has two guide posts 231, which are arranged along the length of the chain bracket 11. The spring 232 is vertically arranged, with its top end abutting against the horizontal frame plate 2391 and its bottom end abutting against the pressure frame 21, thereby providing downward elastic force to the pressure frame 21.

[0020] The working principle of this embodiment is as follows:

[0021] The toothed chain 12 is positioned within the locking groove 111 of the chain bracket 11. The locking groove 111 limits or locks the toothed chain 12, preventing it from detaching from the chain bracket 11. When the edge of the sheet material 9 is pierced by the sharp teeth 121 of the toothed chain 12, and is carried and dragged by the toothed chain 12, the wheel surfaces on both sides of the toothed groove 221 of the pressure wheel 22 press against the top of the sheet material 9, providing downward pressure, thereby preventing the sheet material 9 from detaching from the sharp teeth 121 of the toothed chain 12.
