A feeding device for a cutting machine

Abstract

This utility model discloses a feeding device for a cutting machine, including a frame with a conveyor belt on it. The frame is connected to a machine head, and a feeding assembly linked to the machine head is also provided on the frame. The feeding assembly includes a first mounting bracket and a second mounting bracket that slide on a guide rail of the frame. Lifting components are mounted on the opposing surfaces of the first and second mounting brackets, and a pressure plate is provided between the two lifting components. The machine head moves on the frame to move the pressure plate above the conveyor belt, and the two lifting components descend synchronously to press the leather onto the conveyor belt. When the pressure plate moves downward with the lifting components, it presses the leather waiting to be cut onto the conveyor belt. At this time, with the synchronous movement of the machine head and the conveyor belt, the leather waiting to be cut can be moved to the cutting position. Since the pressure plate can be placed horizontally in the width direction of the leather, the phenomenon of leather twisting due to uneven force is reduced.

Description

Technical Field

[0001] This utility model relates to the technical field of leather cutting equipment, specifically a feeding device for a cutting machine. Background Technology

[0002] To ensure the accuracy of leather cutting, the leather needs to be moved under the cutting blade. However, in the existing technology previously disclosed by our company with announcement number CN222249590U, the common practice is to manually pull one end of the leather and feed it to the cutting blade. This method not only results in low leather cutting efficiency, but also makes the leather prone to twisting when manually pulled, which makes it difficult to control the accuracy of leather cutting. Utility Model Content

[0003] The purpose of this invention is to provide a feeding device for a cutting machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cutting machine feeding device, including a frame, on which a conveyor belt is provided; the frame is connected to a machine head, and the frame is also provided with a feeding assembly that is linked to the machine head; the feeding assembly includes a first mounting frame and a second mounting frame that slide on a guide rail of the frame; lifting components are installed on the opposing surfaces of the first mounting frame and the second mounting frame, and a pressure plate is provided between the two lifting components; by moving the machine head on the frame, the pressure plate is moved above the conveyor belt, and by the synchronous descent of the two lifting components, the leather is pressed tightly onto the conveyor belt.

[0005] As a preferred technical solution of this utility model: both the first mounting bracket and the second mounting bracket are connected to the machine head through a connecting plate.

[0006] As a preferred technical solution of this utility model: a support plate is further provided between the first mounting frame and the second mounting frame, and the support plate moves below the conveyor belt and is located directly below the pressure plate.

[0007] As a preferred technical solution of this utility model: both the first mounting bracket and the second mounting bracket are provided with sliders, and the sliders are slidably engaged with the guide rails on the frame.

[0008] As a preferred technical solution of this utility model: the side of the pressure plate facing the conveyor belt is also provided with a rubber pad.

[0009] As a preferred technical solution of this utility model: the side of the support plate facing the pressure plate is also provided with a support pad.

[0010] The beneficial effects of this utility model by adopting the above technical solution are as follows: the lifting component causes the pressure plate to move downward to press the leather onto the conveyor belt, and then the conveyor belt moves synchronously with the machine head to move the pressed leather to the cutting position. Based on this, the equipment can realize automatic feeding of leather through the feeding component. In particular, the pressure plate can press the leather as a whole, which can effectively avoid the problem of difficulty in controlling the cutting accuracy of leather due to twisting and deformation during the stretching process.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0018] Please see Figure 1-5This utility model provides an embodiment of a cutting machine feeding device, including a frame 1, on which a conveyor belt 4 is provided; the frame 1 is connected to a machine head 2, and the frame 1 is also provided with a feeding assembly 3 that is linked with the machine head 2; the feeding assembly 3 includes a first mounting frame 30 and a second mounting frame 38 that slide on the guide rail of the frame 1; lifting members 36 are installed on the facing surfaces of the first mounting frame 30 and the second mounting frame 38, and a pressure plate 32 is provided between the two lifting members 36; by the movement of the machine head 2 on the frame 1, the pressure plate 32 is moved above the conveyor belt 4, and the two lifting members 36 descend synchronously to press the leather onto the conveyor belt 4.

[0019] In summary, when the pressure plate 32 moves downwards following the lifting component 36, it presses the leather awaiting cutting onto the conveyor belt 4. Simultaneously, with the synchronous movement of the machine head 2 and the conveyor belt 4, the leather awaiting cutting can be moved to the cutting position. Since the pressure plate 32 can be positioned transversely along the width of the leather, it can press the entire leather onto the conveyor belt 4, reducing the distortion caused by uneven force on the leather, thus improving the accuracy of leather cutting. Simultaneously, the feeding component 3 is connected to the machine head 2, ensuring that the moving speed of the feeding component 3 is essentially consistent with the moving speed of the conveyor belt 4, further preventing uneven force on the leather during the pulling process. The lifting component 36 is preferably a cylinder, and the pressure plate 32 is movably connected to the working part of the cylinder.

[0020] Furthermore, since both the first mounting bracket 30 and the second mounting bracket 38 are connected to the machine head 2 via connecting plates 33, this ensures two things: first, the pressure plate 32 and the machine head 2 move synchronously; second, the feeding position of the feeding assembly 3 can be adjusted by replacing the connecting plates 33 with different lengths. For example, the longer the connecting plate 33, the farther the feeding position of the feeding assembly 3 is from the cutting machine 7; conversely, the shorter the connecting plate 33, the shorter the feeding position of the feeding assembly 3 is from the cutting machine 7. One end of the connecting plate 33 is bolted to the mounting plate 6 of the drive assembly 5, and the other end of the connecting plate 33 is bolted to the corresponding mounting bracket.

[0021] Furthermore, since a support plate 31 is provided between the first mounting frame 30 and the second mounting frame 38, and the support plate 31 moves below the conveyor belt 4 and is located directly below the pressure plate 32, the support plate 31 can support the conveyor belt 4 below the conveyor belt 4 while also supporting the pressure plate 32. Therefore, the pressure of the pressure plate 32 on the leather waiting to be cut can be increased, thereby preventing the leather waiting to be cut from falling off during the movement of the feeding assembly 3.

[0022] Preferably, both the first mounting bracket 30 and the second mounting bracket 38 are provided with sliders 37, and the sliders 37 slide in cooperation with the guide rails on the frame 1. Therefore, by using the sliders 37 to cooperate with the guide rails on the frame 1, the directional movement of the feeding assembly 3 can be ensured, and the shaking phenomenon of the feeding assembly 3 during movement can be reduced.

[0023] In order to reduce the damage to the leather waiting to be cut caused by the pressure plate 32, a rubber pad 34 is provided on the side of the pressure plate 32 facing the conveyor belt 4. In addition, the rubber pad 34 can also enhance the friction of the pressure plate 32 on the leather waiting to be cut, which can further prevent the leather from falling off during the pulling process.

[0024] Similarly, the support plate 31 is also provided with a support pad 35 on the side facing the pressure plate 32. Therefore, the support pad 35 supports the rubber pad 34 on the bottom surface of the conveyor belt 4, so that the pressure plate 32 and the support plate 31 can reliably clamp the leather waiting to be cut, so that the leather waiting to be cut can be moved stably and reliably to the cutting position.

[0025] In summary, this equipment utilizes the feeding assembly 3, which moves in tandem with the machine head 2, to automatically feed leather awaiting cutting. The feeding assembly 3 employs sliders 37 on two mounting brackets that slide along the guide rails on the frame 1, thus achieving automatic feeding without altering the overall structure of the frame 1. The two mounting brackets support the pressure plate 32 and the support plate 31, while also supporting the lifting component 36. This results in a compact structure for the feeding assembly 3 while performing the clamping action. In particular, it ensures that the pressure plate 32 and the support plate 31 move synchronously, and that the pressure plate 32 accurately presses onto the support plate 31 each time it descends, thereby improving the clamping force and reliability of the pressure plate 32 and the support plate 31 on the leather awaiting cutting. Furthermore, all parts of the feeding assembly 3, except for the lifting component 36, can be assembled from sheet metal and then welded together, thus reducing manufacturing costs and consequently lowering equipment operating and maintenance costs.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
