Description

Technical Field

[0001] This utility model relates to the technical field of shoe raw material processing equipment, and in particular to a raw material cutting device for shoe production. Background Technology

[0002] The raw materials used in shoe manufacturing are diverse, and each material plays its own role in shoe production. For example, natural leather (such as cowhide and sheepskin, which have good breathability, flexibility, and durability), artificial leather (such as PU leather and PVC leather, which are relatively inexpensive and easy to process and maintain), fabrics (such as canvas and mesh, which have good breathability and are often used in sports shoes and casual shoes), and synthetic materials (such as TPU and EVA, which have good elasticity and support).

[0003] In the shoe manufacturing process, raw materials need to be cut into uppers so that they can be assembled with components such as the sole to complete the shoe production. Traditionally, upper cutting involves workers using scissors and other tools to cut the leather, fabric, or other materials according to pre-drawn or patterned shapes. With the development of industrial technology, cutting tools have changed, such as automatic fabric cutting machines and CNC leather cutting machines.

[0004] Automatic fabric cutting machines are commonly used for cutting multi-layered fabric shoe materials. They are equipped with blades that move up and down, allowing them to cut multiple layers of fabric along a set path. CNC leather cutting machines are suitable for cutting multi-layered leather or synthetic leather shoe upper materials.

[0005] Whether it's an automatic fabric cutting machine or a CNC leather cutting machine, they can cut multiple layers of raw materials distributed vertically, thereby simultaneously cutting out multiple shoe uppers and improving shoe production efficiency.

[0006] However, at the end of shoe material production, in order to facilitate the storage and transportation of shoe materials, fabrics and other materials are usually rolled up. Therefore, when using rolled fabrics and other materials for shoe upper cutting, the rolled fabric needs to be cut first, and the cut fabrics are stacked one on top of the other so that multiple shoe uppers can be cut simultaneously by an automatic fabric cutting machine.

[0007] As can be seen from the actual shoe production process, the cutting of shoe raw materials is usually done manually, and the cut materials are stacked one on top of the other. This operation method is inefficient and may not be able to supply shoe upper cutting. At the same time, the labor intensity of the workers is high. Utility Model Content

[0045] It should be noted that the terms "a" and "a plurality of" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0046] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0047] To improve the efficiency of manual cutting of shoe raw materials, and to allow for the stacking of cut materials for processing by a cutting device, this embodiment provides a raw material cutting device. This cutting device reciprocates, pulling the ends of rolled-up fabrics and laying the ends of the fabric rolls onto the already stacked cut materials. The cutting device then cuts the ends of the fabric rolls. Repeating this process allows for the cutting and stacking of fabric, which is more efficient than manual labor and effectively reduces the workload of workers.

[0048] like Figure 1As shown, the cutting device specifically includes a frame 1, a support conveyor belt 2, a pulling mechanism 3, and a slitting mechanism 4. The support conveyor belt 2 is located at the top of the frame 1 and runs along its length. Support rollers are installed at both ends of the support conveyor belt 2, and one end of each support roller is connected to the drive output shaft of a first motor (such as a servo motor or stepper motor). Therefore, when the fabric being cut is stably supported by the support conveyor belt 2, the rotation of the support conveyor belt 2 can be controlled by the operation of the motor (such as a servo motor or stepper motor), thereby controlling the movement of multi-layered stacked fabrics, facilitating their removal and transfer to the next process. The pulling mechanism 3 is located above the frame 1 and runs along its length. The slitting mechanism 4 is located at the end of the frame 1, adjacent to the pulling mechanism 3. Therefore, the fabric end placed on the slitting mechanism 4 can be clamped by the pulling mechanism 3, and the fabric can be moved and laid on the supporting conveyor belt 2, or placed on the already cut fabric, and then the slitting mechanism 4 can cut the fabric. Thus, with the cooperation of the slitting mechanism 4 and the pulling mechanism 3, the fabric roll can be cut and the cut fabric can be stacked up and down.

[0049] When using the above-mentioned cutting device, a device for supporting the fabric roll needs to be provided on the outer side of the end of the cutting device where the slitting mechanism 4 is located, so as to control the rotation of the fabric roll to loosen the fabric.

[0050] like Figure 5 , Figure 6 As shown, in order to pull the end of the fabric and thus control its movement, the pulling mechanism 3 includes a mating plate 37, a clamping plate 36, a horizontal plate 33, a first telescopic cylinder 35, two guide plates 31, and two drive belts 32. The two guide plates 31 are respectively located at both ends of the horizontal plate 33 and at the two long edges of the frame 1. The two drive belts 32 are paired with the two guide plates 31 one by one. In addition, the drive belts 32 can rotate under the operation of a second motor (such as a servo motor or a stepper motor), thereby controlling the horizontal plate 33 to move along the length of the guide plates 31 and providing power for pulling the fabric. The horizontal plate 33 is configured as an inverted T-shaped structure, and the first telescopic cylinder 35 is connected to the vertical section of the horizontal plate 33 via the clamping plate 351. At the same time, the bottom of the first telescopic cylinder 35 is connected to the clamping plate 36. The mating plate 37 is set on the side of the horizontal plate 33 and is located below the clamping plate 36. Therefore, when the horizontal plate 33 is set near the cutting mechanism 4, the first telescopic cylinder 35 controls the clamping plate 36 to descend, thereby cooperating with the mating plate 37 to clamp the end of the fabric and provide support for controlling the movement of the fabric.

[0051] like Figure 5As shown, to control the movement of the horizontal plate 33 along the length of the guide plate 31, each drive belt 32 is arranged along the length of the guide plate 31, and support wheels 34 are provided at both ends of the inner side of each drive belt 32. The central axis of the support wheels 34 is connected to the power output horizontal axis of the second motor. Therefore, the rotation of the two drive belts 32 can be controlled by the second motor. To control the rotation of the two drive belts 32, a transmission shaft can be provided between the two drive belts 32 and the same support wheel 34. This transmission shaft is connected to the central axis of the support wheel 34 via a coupling. Therefore, the forward and reverse rotation of the two drive belts 32 can be controlled by one motor. The drive belts 32 and support wheels 34 here can be configured similarly to synchronous belts and synchronous pulleys.

[0052] like Figure 4 , Figure 6 , Figure 7 As shown, end brackets 38 are provided at both ends of the horizontal plate 33, and connecting bolts 385 are threaded into the top surface of the end brackets 38. The end brackets 38 are located inside the drive ring belt 32, and the connecting bolts 385 penetrate the upper side wall of the drive ring belt 32. Therefore, the drive ring belt 32 is connected to the end brackets 38 by the action of the connecting bolts 385, and thus the horizontal plate 33 is driven to reciprocate when the two drive ring belts 32 rotate.

[0053] like Figure 7 As shown, to ensure the horizontal plate 33 is stably and movably mounted on the guide plate 31, one end of the end frame 38 is fixedly provided with an insertion tube 381, which is bolted to the end of the horizontal plate 33. The other end of the end frame 38 is provided with a limiting roller 382, ​​and a limiting wheel 383 is provided on the side of the limiting roller 382. The guide plate 31 is disposed through the space formed by the limiting roller 382 and the limiting wheel 383, with the edge of the guide plate 31 extending into the limiting wheel 383. Therefore, with the cooperation of the limiting roller 382 and the limiting wheel 383, the end frame 38 can be stably placed relative to the guide plate 31, and the resistance to movement of the end frame 38 relative to the guide plate 31 can be reduced by the rotation of the limiting roller 382 and the limiting wheel 383.

[0054] like Figure 7 As shown, to facilitate the mounting of the limiting roller 382 and the limiting wheel 383 on the side of the guide plate 31, a top frame 384 is provided on the top of the limiting wheel 383. Multiple bolts are threaded through the top frame 384, with the ends of the bolts threaded into the end frame 38. The bolts can be removed when needed to release the restriction of the limiting roller 382 and the limiting wheel 383, facilitating the mounting of the end frame 38 onto the guide plate 31.

[0055] like Figure 8As shown, to enable fabric cutting, the slitting mechanism 4 includes a slitting blade 43, a support plate 47, a U-shaped frame 44, and a second telescopic cylinder 41. The U-shaped frame 44 is installed at the end of the frame 1, and its top is open. A top plate 42 is provided on the top of the U-shaped frame 44. The second telescopic cylinder 41 is inverted and installed on the top plate 42, and its telescopic end is connected to the slitting blade 43. The support plate 47 is located below the slitting blade 43 and is installed on the side of the U-shaped frame 44 away from the frame 1. The upper side of the support plate 47 is higher than the upper side of the conveyor belt 2. When fabric needs to be cut, the fabric output from the fabric roll is placed on the support plate 47 and moves on it. Then, under the operation of the second telescopic cylinder 41, the slitting blade 43 can be raised and lowered, cooperating with the support plate 47 to complete the fabric cutting process.

[0056] like Figure 8 As shown, in order to reduce the probability of damage to the slitting blade 43 and complete the fabric cutting process, a groove 45 is provided on the tray 47, and the groove 45 is adapted to the blade of the slitting blade 43.

[0057] like Figure 8 As shown, to restrict the movement of the fabric, a roller 46 is also provided on the pallet 47, and the sole material passes through the gap between the pallet 47 and the roller 46. A motor can also be provided at the end of the roller 46, and the rotation of the roller 46 can be controlled by the operation of the motor. In addition, another roller 46 can be provided below the roller 46, which passes through the pallet 47 and whose top is flush with the upper side of the pallet 47. The movement of the fabric on the pallet 47 can be controlled by the cooperation of the two rollers 46.

[0058] like Figure 8 As shown, to ensure the top plate 42, slitting blade 43, and support plate 47 are stably mounted on the C-shaped frame 44, sleeves are provided at the ends of the top plate 42, slitting blade 43, and support plate 47. These sleeves are fitted onto the C-shaped frame 44, and the sleeves of the top plate 42 and support plate 47 are connected to the C-shaped frame 44 by bolts. The sleeve of the slitting blade 43 moves relative to the C-shaped frame 44. To reduce the resistance and wear between the sleeves and the C-shaped frame 44, the coefficient of friction at their contact surfaces can be reduced through precision machining and polishing. Lubricant can also be applied to the contact surfaces, or even polytetrafluoroethylene (PTFE), a material with a very low coefficient of friction, can be used to manufacture the C-shaped frame 44 and the sleeves.

[0059] like Figure 3 , Figure 4As shown, to stably support the fabric on the supporting conveyor belt 2, a supporting plate 21 is provided on the inner side of the supporting conveyor belt 2. A bottom tube 22 is fixedly installed on the bottom surface of the supporting plate 21, and a support plate 23 is installed through the bottom tube 22. A bracket 24 is sleeved at the end of the support plate 23, and the bottom of the bracket 24 is inserted into the connecting hole 11 of the frame body 1. Therefore, under the action of the supporting plate 21, the strength of the top wall of the supporting conveyor belt 2 can be enhanced, thereby stabilizing the fabric under the action of the supporting conveyor belt 2.

[0060] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this utility model.

[0061] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications can be made based on the above-described invention, and these changes or modifications still fall within the scope of the present invention.
