Abstract
Description
Technical Field
[0001] This utility model relates to a shoe upper fabric cutting device. Background Technology
[0002] With the rapid development of the footwear industry, the precision and efficiency of shoe upper fabric cutting have become key factors affecting product quality and production costs. Traditional shoe upper fabric cutting mainly relies on manual or mechanical operations.
[0003] Manual operation is extremely inefficient and is now mainly used for the handcrafting of high-end shoes, making it unsuitable for mass production.
[0004] The machine is operated using a die-cutting blade, which cuts multiple layers of fabric simultaneously as the blade moves downwards, resulting in high cutting efficiency.
[0005] However, in the existing technology, the die-cutting blade is a single unit, and it can only complete one cut per run. Although it is more efficient than manual labor, it is still somewhat insufficient for mass production.
[0006] Based on the above problems, we designed a shoe upper fabric cutting device that can simultaneously complete cutting at multiple locations and can also automatically feed materials to improve cutting speed. Utility Model Content
[0007] The technical problem to be solved by this utility model is to provide a shoe upper fabric cutting device that can simultaneously complete cutting at multiple positions and can also automatically feed materials to improve cutting speed.
[0008] To solve the above problems, the present invention adopts the following technical solution:
[0009] A shoe upper fabric cutting device includes a frame, a cutting table that slides laterally on the inner side of the frame, driving devices for driving the cutting table to slide laterally are installed at the front and rear ends of the frame, a first driving device is installed at the top of the frame, and a pressure knife structure and a pressure plate structure are installed inside the frame above the cutting table. The pressure knife structure and the pressure plate structure are elastically connected. The first driving device drives the pressure knife structure downward. A passive push rod is installed at the inner top of the frame, and the lower end of the passive push rod is inserted into the pressure knife structure.
[0010] Preferably, the cutting table includes a table plate, with supports welded to both sides of the bottom of the table plate, and rollers fixed to the outside of the supports, which contact the ground. Racks are installed at the front and rear ends of the table plate. The driving device is a servo geared motor, and a gear is fixed to the output end of the driving device. The gear meshes with the rack. Slots for passing through the gear are opened at the front and rear end faces of the frame.
[0011] Preferably, a support roller is longitudinally installed inside the frame, and a bearing is fitted between the support roller and the frame. The support roller is supported on the bottom of the platform.
[0012] Preferably, vertical grooves are provided on the front and rear sides of the frame, and guide rods are fixed in the vertical grooves. Both the pressure knife structure and the pressure plate structure are guided by the guide rods.
[0013] Preferably, the pressure knife structure includes an upper pressure plate, a die-cutting knife is fixed at the bottom of the upper pressure plate, and multiple die-cutting knives are provided. The first driving device is a hydraulic push rod, the movable end of the first driving device is fixed to the upper pressure plate, a through hole is provided at the top of the upper pressure plate to penetrate the inner side of the die-cutting knife, the passive push rod is inserted through the through hole, and guide sleeves that cooperate with the guide rod are welded on both sides of the upper pressure plate.
[0014] Preferably, the pressure plate structure includes a lower pressure plate, a through groove is provided at the middle position of the lower pressure plate, and first guide sleeves that cooperate with the guide rod are fixed on both sides of the lower pressure plate. A spring is sleeved on the guide rod, the upper end of the spring is welded and fixed to the guide sleeve, and the lower end of the spring is welded and fixed to the first guide sleeve. After the upper pressure plate moves downward, the die-cutting knife passes through the through groove.

[0016] The beneficial effects of this utility model are:
[0017] This device employs a downward-moving pressure structure, allowing for simultaneous cutting at multiple positions in a single downward motion. After cutting, the pressure structure moves upward, causing the cutting table to shift laterally and adjust the fabric's position for the next cut, resulting in higher overall cutting efficiency. The downward movement of the pressure plate structure further compresses the fabric, making it more stable during cutting. This simple and efficient device is suitable for widespread use.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] See Figure 1 , Figure 2 and Figure 3The illustrated shoe upper fabric cutting device includes a frame 1. A cutting table 2 is laterally slidably mounted on the inner side of the frame 1. A drive device 3 for driving the cutting table 2 to slide laterally is mounted on both the front and rear ends of the frame 1. A first drive device 7 is mounted on the top of the frame 1. Inside the frame 1, above the cutting table 2, a pressure knife structure 4 and a pressure plate structure 5 are mounted. The pressure knife structure 4 and the pressure plate structure 5 are elastically connected. The first drive device 7 drives the pressure knife structure 4 downward. A passive push rod 6 is mounted on the inner top of the frame 1. The lower end of the passive push rod 6 is inserted into the pressure knife structure 4.
[0029] In the above technical solution, the cutting table 2 is driven to move laterally by the driving device 3. The fabric used to make the shoe upper is stacked on top of the cutting table 2. The fabric moves to the inside of the frame 1 and is directly facing the pressure knife structure 4 and the pressure plate structure 5. The pressure knife structure 4 is driven downward by the first driving device 7, and the pressure plate structure 5 moves downward accordingly. The pressure plate structure 5 presses against the surface of the fabric being cut. As the pressure knife structure 4 continues to press down, it completes the cutting of the fabric. After cutting, the pressure knife structure 4 and the pressure plate structure 5 move upward, and the residual fabric remaining in the pressure knife structure 4 is pushed out by the passive push rod 6.
[0030] This device can be used in conjunction with a servo system. The program is set through the controller, and the displacement of the cutting table 2 is set for each movement. When the displacement is reached, the pressure knife structure 4 completes one downward movement and one upward movement.
[0031] This device can also be operated manually. The sliding amount of the cutting table 2 can be controlled through the control panel. When it reaches the desired position, the first drive device 7 can be operated to move downward and upward.
[0032] See Figure 1 As shown, the cutting table 2 includes a table plate 21, with brackets 22 welded to both sides of the bottom of the table plate 21. Rollers 23 are fixed to the outside of the brackets 22, and the rollers 23 contact the ground. Racks 24 are installed at the front and rear ends of the table plate 21. The driving device 3 is a servo geared motor. A gear 31 is fixed to the output end of the driving device 3. The gear 31 meshes with the rack 24. Slots 121 for passing through the gear 31 are opened at the front and rear end faces of the frame 1.
[0033] In the above technical solution, racks 24 are installed on both the front and rear sides of the platform 21, and two drive devices 3 are also set in the front and rear respectively. The platform 21 is driven to move laterally by the synchronous operation of the gears 31 on both sides.
[0034] See Figure 1As shown, a support roller 131 is longitudinally installed inside the frame 1, and a bearing 141 is fitted between the support roller 131 and the frame 1. The support roller 131 is supported on the bottom of the platform 21.
[0035] In the above technical solution, the support roller 131 is used to support the bottom of the platform 21, thereby increasing the pressure-bearing capacity of the platform 21.
[0036] See Figure 1 As shown, vertical grooves 151 are provided on the front and rear sides of the frame 1, and guide rods 161 are fixed in the vertical grooves 151. The pressure knife structure 4 and the pressure plate structure 5 are both guided by the guide rods 161.
[0037] In the above technical solution, the design of the guide rod 161 makes the displacement of the pressure knife structure 4 and the pressure plate structure 5 more accurate.
[0038] See Figure 2 , Figure 3 and Figure 4 As shown, the pressure knife structure 4 includes an upper pressure plate 41, and a die-cutting knife 42 is fixed at the bottom of the upper pressure plate 41. Multiple die-cutting knives 42 are provided. The first driving device 7 is a hydraulic push rod. The movable end of the first driving device 7 is fixed to the upper pressure plate 41. A through hole 43 is provided at the top of the upper pressure plate 41, which penetrates the inner side of the die-cutting knife 42. The passive push rod 6 is inserted through the through hole 43. Guide sleeves 44 that cooperate with the guide rod 161 are welded on both sides of the upper pressure plate 41.
[0039] In the above technical solution, the upper pressure plate 41 is pushed down by the hydraulic push rod, and the fabric is cut by the die-cutting knife 42.
[0040] See Figure 2 , Figure 3 and Figure 4 As shown, the pressure plate structure 5 includes a lower pressure plate 51, with a through groove 52 at the middle position of the lower pressure plate 51. First guide sleeves 53 that cooperate with the guide rod 161 are fixed on both sides of the lower pressure plate 51. A spring 171 is sleeved on the guide rod 161. The upper end of the spring 171 is welded and fixed to the guide sleeve 44, and the lower end of the spring 171 is welded and fixed to the first guide sleeve 53. After the upper pressure plate 41 moves downward, the die-cutting knife 42 passes through the through groove 52.
[0041] In the above technical solution, the lower pressure plate 51 first contacts the fabric to fix the fabric and ensure the stability of the fabric during cutting.
[0042] The lower pressure plate 51 first contacts the fabric, and then the upper pressure plate 41 continues to move downward. At this time, the spring 171 is compressed until the die-cutting blade 42 passes through the through groove 52 and completes the cutting of the fabric.
[0043] See Figure 2 and Figure 4 As shown, a push plate 661 is welded to the lower end of the passive push rod 6. The passive push rod 6 is a hollow rod. A vent hole 662 corresponding to the inner cavity of the passive push rod 6 is provided in the middle of the push plate 661. An exhaust hole 663 is provided through the passive push rod 6 near the upper end.
[0044] The height of the push plate 661 is fixed. As the upper pressure plate 41 moves upward, the push plate 661 pushes out the fabric remaining in the die-cutting knife 42.
[0045] The ventilation holes 662 and vent 663 maintain the pressure balance inside and outside the die-cutting blade 42, reducing fabric residue.
