Description

Technical Field

[0001] This utility model relates to the field of leather conveying technology, specifically to a highly stable conveying device for softened leather. Background Technology

[0002] As a fundamental component of automotive carpets, carpet substrates must possess excellent wear resistance, water resistance, and flame retardancy. Common carpet substrates currently on the market include PVC, PP, and PET. Carpet foaming involves laying the leather material on the surface of a mold, then drawing a vacuum, and then moving it into a foaming module for foaming treatment, thus completing the carpet foaming process.

[0003] In carpet foaming, the leather material needs to be covered on the mold, and then the vacuum between the leather material and the mold is extracted to shape the leather material. Then, the mold and leather material are placed in the foaming mold frame for foaming treatment. During the conveying of the leather material, the conveying equipment causes a situation where, after most of the leather material is conveyed out, only a small portion of the leather material remains on the conveying equipment. Because the center of the leather material is lower, the material feeding speed will increase in the later stages of conveying, resulting in the inability to completely cover the mold and affecting the subsequent foaming.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a frame, on which a frame is slidably mounted via a guide chain, and two guide rods are rotatably connected inside the frame, with a mesh strip rotatably mounted outside the two guide rods;

[0006] It also includes a heating system, which is disposed within the frame and located at the bottom of the mesh belt, for heating and softening the leather;

[0007] It also includes a bending assembly for bending the mesh belt to convey the softened leather out of the mesh belt. The bending assembly includes a bending rod rotatably disposed in the mesh belt and two first swing arms. The two ends of the bending rod pass through the two first swing arms and are rotatably connected to the frame. The front end of the first swing arm is rotatably connected to a guide rod.

[0008] It also includes pressure bars, which are used to press the material during the bending assembly's bending and conveying of the mesh belt, so as to ensure stable conveying of the material.

[0009] As a further description of the above technical solution:

[0010] The bending assembly also includes two cylinders fixed to the frame. The output ends of the two cylinders are fixedly connected to transition shafts.

[0023] In the above technical solution, the softening leather material high-stability conveying device provided by this utility model has the following beneficial effects:

[0024] This invention utilizes a guide chain to drive the frame to move within the frame, facilitating the placement of leather onto a mesh belt. The mesh belt then drives the leather to move into a heating system for softening. After softening, the mesh belt transports the leather to the mold. A bending assembly drives the mesh belt to bend, slowing down the material feeding speed. During feeding, the angle of the bending assembly gradually decreases to overcome the feeding speed.

[0041] It also includes a bending assembly for bending the mesh belt 31 to convey the softened leather out of the mesh belt 31. The bending assembly includes a bending rod 55 rotatably disposed in the mesh belt 31 and two first swing arms 54. The two ends of the bending rod 55 pass through the two first swing arms 54 respectively and are rotatably connected to the frame 3. The front end of the first swing arm 54 is rotatably connected to the guide rod 32. The first swing arm 54 is V-shaped. By moving one end, the other end is rotated, thereby completing the bending of the mesh belt 31.

[0042] It also includes a pressure bar 6, which presses the material when the bending assembly bends and conveys the leather to the mesh belt 31, so as to ensure stable conveying of the leather.

[0043] In a further embodiment of this utility model, the bending assembly also includes two cylinders 51 fixed on the frame 3. The output ends of the two cylinders 51 are fixedly connected to transition shafts 52. Connecting rods 53 are sleeved inside the two transition shafts 52. The ends of the two connecting rods 53 are rotatably connected to the two first swing arms 54 respectively.

[0044] In a further embodiment of this utility model, the bending assembly also includes two cylinders 51 fixed on the frame 3. The output ends of the two cylinders 51 are fixedly connected to transition shafts 52. Connecting rods 53 are sleeved inside the two transition shafts 52. The ends of the two connecting rods 53 are rotatably connected to the two first swing arms 54 respectively.

[0045] Furthermore, the pressure rod 6 assembly includes two hydraulic cylinders 71 fixed on the frame 3. The output end of the hydraulic cylinder 71 is fixedly connected to a connecting shaft 72. The end of the connecting shaft 72 is fixedly connected to a transition chain 73. The end of the transition chain 73 is rotatably connected to a second swing arm 74. Both second swing arms 74 are rotatably connected to both ends of the pressure rod 6.

[0046] Furthermore, each of the two second swing arms 74 has a fixedly connected positioning rod 75 on its opposite side, and the positioning rod 75 is rotatably connected to the frame 3.

[0047] In the embodiment provided by this utility model, a positioning rod 75 is fixedly connected to one side of each of the two second swing arms 74 facing away from each other, and the positioning rod 75 is rotatably connected to the frame 3.

[0048] Specifically, the drive assembly includes guide sprockets 82 fixed at both ends of two guide rods 32, two guide chains on the same side externally meshing with the same first chain 83, and a driven sprocket 86 rotatably connected to the guide rod 32 on the side away from the cylinder 51.

[0049] In a further embodiment of this invention, a protective plate 84 is fixedly connected to the frame 3, and a drive sprocket 85 is rotatably connected inside the protective plate 84. The drive sprocket 85 and the driven sprocket 86 are externally meshed with the same second chain 87. A reduction motor 81 is provided on the frame 3, and the output end of the reduction motor 81 is connected to the drive sprocket 85. A reversing mechanism is provided at the output end of the reduction motor 81, and the reversing mechanism is connected to the drive sprocket 85 so that the reduction motor 81 and the drive sprocket 85 can be set perpendicularly.

[0050] Working principle: The frame 3 is moved backward by the guide chain 4, so that the mesh belt 31 on the rear side is removed from the frame 1. Then the leather is laid flat on the mesh belt 31. The leather on the mesh belt 31 is then moved above the heating system 2 by the guide chain 4. The heating system 2 then heats and softens the leather. After softening, a part of the front side of the frame 3 is removed from the frame 1 by the guide chain 4.

[0051] Then, the drive sprocket 85 is driven to rotate by the geared motor 81, and the driven sprocket 86 is driven to rotate by the second chain 87, thereby causing the guide rod 32 to rotate, and the guide sprocket 82 to rotate synchronously, thereby driving the first sprocket to rotate, and causing the two guide sprockets 82 to drive the two guide rods 32 to rotate, so that the mesh belt 31 can transport the heated leather to the removal frame 1.

[0052] Then the mesh belt 31 continues to convey material, removing a portion of the leather from the mesh belt 31 and covering the mold. The transition shaft 52 is then moved to the left by the cylinder 51 (as shown). Figure 5 , 6 As shown), the connecting rod 53 drives the first swing arm 54 to rotate around the bending rod 55 as the pivot, which in turn causes the rotating rod to rotate downward around the bending rod 55 as the pivot, thereby causing the mesh belt 31 to bend downward to facilitate the discharge of the leather material.

[0053] During the material feeding process, the guide chain 4 drives the frame 3 to move backward gradually. During the backward movement, the cylinder 51 drives the transition shaft 52 to move to the right, thereby driving the first swing arm 54 to rotate clockwise. This causes the first swing arm 54 to gradually rotate and reset, thus overcoming the speed at which the material falls due to gravity and ensuring uniform feeding of the material.

[0054] Just before the leather is completely discharged, the hydraulic cylinder 71 drives the connecting shaft 72 to move towards the transition chain 73, causing the transition chain 73 to relax. This allows the second swing arm 74 to rotate downwards around the positioning rod 75 under the gravity of the pressure rod 6, thus pressing down on the leather. As the leather is about to be discharged, the speed at which it falls due to gravity is further reduced, preventing the leather from falling completely in a short time and ensuring that the leather can evenly cover the mold.

[0055] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
