Description

Technical Field

[0001] This utility model relates to the technical field of shoe upper production equipment, specifically a die-cutting device for producing flyknit shoe uppers. Background Technology

[0002] Shoes are mainly composed of two parts: the sole and the upper. In the processing of one-piece uppers, the raw materials of the fabric are often processed according to the production requirements to shape the upper. This includes the production of flyknit uppers. Flyknit uppers have excellent ventilation. After weaving, they are a single piece of material. They need to be die-cut piece by piece using a cutting machine and a die-cutting knife. Because flyknit uppers are made of mesh material and can only be cut in single layers, it is difficult to cut the flyknit upper in one go during actual production. It is necessary to increase the cutting pressure, which may cause the die-cutting plate to be pressed deeply by the die-cutting knife, resulting in uneven wear on the die-cutting plate. Sometimes, even with increased cutting pressure, the flyknit upper cannot be cut in one go, and manual assistance is required to cut it.

[0003] Furthermore, the application document with publication number CN221599349U mentions a die-cutting device for producing flyknit shoe uppers. This device first places the woven flyknit shoe upper material on the top surface of a die-cutting plate. Then, the die-cutting blades are manually aligned with the individual pieces of flyknit shoe upper material. Next, a telescopic device extends downwards, causing the pressure plate assembly to press down on each die-cutting blade, causing them to cut the flyknit shoe upper material. At this point, each die-cutting blade exerts only slight pressure on the die-cutting plate, thus reducing wear on the plate. Finally, each electromagnet is energized to generate magnetism, attracting each die-cutting blade. Then, the ultrasonic vibration generator is activated, driving the die-cutting plate to vibrate ultrasonically through the vibration clamp. This causes the flyknit upper material to be broken by ultrasonic vibration between the die-cutting plate and each die-cutting blade, resulting in a single piece of flyknit upper. Then, the electromagnets are de-energized, the ultrasonic vibration generator stops, and the telescopic device drives the pressure plate assembly to rise. Finally, the workers manually remove the die-cutting blades and the single piece of flyknit upper and repeat the die-cutting operation in the same way for the next round. However, there are still some defects that need to be optimized. The specific defects are as follows: The die-cutting blades in this equipment need to be manually placed, which reduces production efficiency.

[0004] Therefore, it is particularly important to design a die-cutting device for the production of flyknit shoe uppers to overcome the above-mentioned technical defects and improve the overall practicality. Utility Model Content

[0005] The purpose of this invention is to provide a die-cutting device for the production of knitted shoe uppers, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A die-cutting device for producing flyknit shoe uppers includes a main body, a hydraulic rod at the top of the main body, a connecting plate at the output end of the hydraulic rod, spring-damped shock absorbers at the four corners of the bottom of the connecting plate, a vibrator at one end of each spring-damped shock absorber, a mounting plate connected to the vibrator, a die-cutting blade inside the mounting plate, a die-cutting plate at the bottom of the die-cutting blade, and a vacuum pump assembly inside the main body.

[0008] As a preferred embodiment of this utility model, the mounting plate has a slot inside, and the die-cutting blade has a block. The block and the slot are compatible, and the mounting plate and the block are fixed in position by bolts.

[0009] As a preferred embodiment of this utility model, the vacuum pump assembly includes a vacuum pump and a suction cup, the suction cup is provided with a sealing ring, and the vacuum pump is disposed at a relative position on the bottom of the die-cutting plate.

[0010] As a preferred embodiment of this utility model, a plurality of ventilation holes are equally spaced on the die-cutting plate, and a placement frame is provided on the top of the main body. The die-cutting plate is placed inside the placement frame, and the placement frame and the die-cutting plate are connected by bolts.

[0011] As a preferred embodiment of this utility model, the mounting plate is provided with limiting blocks symmetrically on both sides, the limiting blocks are provided with limiting holes inside, the limiting holes are provided with a plurality of compression springs inside, one end of the compression spring is provided with a roller, the limiting holes are provided with a positioning rod inside, and the positioning rod is provided with a sliding groove for matching the roller.

[0012] As a preferred embodiment of this utility model, a pressure sensor is provided on the bottom surface of the limiting block to monitor the pressure changes generated during the die-cutting process in real time.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model discloses a die-cutting device for producing knitted shoe uppers. Utilizing a structure comprising a hydraulic rod, connecting plate, spring-damped shock absorber, vibrator, mounting plate, and vacuum pump assembly, the vacuum pump assembly holds the shoe upper material firmly in place during die-cutting, ensuring precision. The hydraulic rod drives the die-cutting mechanism to descend smoothly. Combined with the precise cooperation of the limiting block and rollers, this achieves directional movement of the die-cutting blade and real-time monitoring by the pressure sensor. At critical moments in die-cutting, the vibrator automatically activates, using slight vibration to assist the die-cutting blade in penetrating the material, further optimizing the cutting effect. After die-cutting, the device automatically resets, and the vacuum pump releases the material, allowing operators to easily remove the finished product. Furthermore, the replaceable die-cutting plate and blade allow the device to flexibly meet various shoe upper die-cutting needs, solving the problem of manually placing the die-cutting blade, which reduces production efficiency.

[0023] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0024] A die-cutting device for producing knitted shoe uppers includes a main body 1. A hydraulic rod 101 is located at the top of the main body 1. A connecting plate 102 is located at the output end of the hydraulic rod 101. Spring-damped shock absorbers 103 are located at the four corners of the bottom of the connecting plate 102. One end of each spring-damped shock absorber 103 is connected to a vibrator 104. The vibrator 104 is connected to a mounting plate 105. A die-cutting blade 106 is located inside the mounting plate 105. A die-cutting plate 107 is located at the bottom of the die-cutting blade 106. A vacuum pump assembly 108 is located inside the main body 1. The shoe upper material to be die-cut is placed oriented on the die-cutting plate 107. The vacuum pump assembly 108 is then activated. The vacuum pump uses a suction cup and its sealing ring to adsorb and fix the shoe upper material, further enhancing its stability and preventing displacement during the die-cutting process. Then, the hydraulic rod 101 begins to work, pushing... The moving connecting plate 102 and the vibrator 104 and mounting plate 105 below it move downwards. During the descent of the die-cutting blade, the rollers in the limiting blocks on both sides of the mounting plate 105 slide smoothly along the grooves on the positioning rod, realizing the directional up and down displacement of the die-cutting blade. At the same time, the pressure sensor on the bottom surface of the limiting block monitors the pressure changes during the die-cutting process in real time to ensure that the die-cutting force is appropriate and stable. When the die-cutting blade 106 contacts the shoe upper material, the vibrator 104 starts to work, generating slight vibration to help the die-cutting blade penetrate the material better and improve the die-cutting effect. After the die-cutting is completed, the hydraulic rod 101 drives the entire die-cutting mechanism to rise and return to its original position. At this time, the vacuum pump assembly 108 releases the material, and the operator can take away the finished product after die-cutting. At the same time, the die-cutting plate and the die-cutting blade can be replaced to adapt to the die-cutting needs of shoe uppers of different shapes and sizes.

[0025] The mounting plate 105 has a slot inside, and the die-cutting blade 106 has a locking block. The locking block and the slot are compatible with each other. The mounting plate 105 and the locking block are fixed in position by bolts. The die-cutting blade 106 is installed through the cooperation between the mounting plate 105 and the locking block, which facilitates the replacement of different die-cutting blades later. In addition, in order to facilitate the fixing of the position of the die-cutting blade, the vacuum pump assembly 108 includes a vacuum pump and a suction cup. The suction cup is equipped with a sealing ring. The vacuum pump is set at a relative position at the bottom of the die-cutting plate 107. The vacuum pump assembly 108 is used to fix the position of the shoe upper material to prevent displacement during die-cutting. Several ventilation holes are evenly spaced on the die-cutting plate 107. The main body 1 has a placement frame on its top, and the die-cutting plate 107 is placed inside the placement frame. The placement frame and the die-cutting plate 107 are connected by bolts. The placement frame and the die-cutting plate 107 are used to orient the placement of the shoe upper material. The mounting plate 105 has symmetrical limit blocks on both sides. The limit blocks have limit holes inside, and several compression springs are provided inside the limit holes. One end of the compression spring is provided with a roller. The limit holes have positioning rods inside, and the positioning rods have grooves for matching the rollers. The positioning rods facilitate the orienting and vertical displacement of the die-cutting blade. The bottom surface of the limit blocks is provided with pressure sensors to monitor the pressure changes generated during the die-cutting process in real time.

[0026] The working process of this utility model is as follows: When using this die-cutting equipment for producing flyknit shoe uppers, the shoe upper material to be die-cut is first placed oriented on the die-cutting plate 107. Then, the vacuum pump assembly 108 is started. The vacuum pump uses a suction cup and its sealing ring to adsorb and fix the shoe upper material, further enhancing its stability and preventing displacement during the die-cutting process. Next, the hydraulic rod 101 starts working, pushing the connecting plate 102 and the vibrator 104 and mounting plate 105 below it to move downwards. During the descent of the die-cutting blade, the rollers in the limiting blocks on both sides of the mounting plate 105 slide smoothly along the grooves on the positioning rod. The die-cutting blade is oriented to move up and down, while the pressure sensor on the bottom of the limiting block monitors the pressure changes in real time during the die-cutting process to ensure appropriate and stable die-cutting force. When the die-cutting blade 106 contacts the shoe upper material, the vibrator 104 starts to work, generating slight vibrations to help the die-cutting blade penetrate the material better and improve the die-cutting effect. After the die-cutting is completed, the hydraulic rod 101 drives the entire die-cutting mechanism to rise and return to its original position. At this time, the vacuum pump assembly 108 releases the material, and the operator can take away the die-cut finished product. At the same time, the die-cutting plate and die-cutting blade can be replaced to adapt to the die-cutting needs of shoe uppers of different shapes and sizes.
