Detailed Implementation

[0031] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0032] like Figure 1-4 As shown, this utility model discloses a technical solution, a die-cutting device for multi-purpose ultra-narrow products, including a support frame 1. Support plates 23 are welded or bolted to the four bottom corners of the support frame 1 to enhance the stability of the device. Lifting rings 24 are threaded to the four top corners to facilitate the handling of the device.

[0033] The upper surface of the support frame 1 is provided with a conveying guide assembly 3 and a cutting assembly 4 in sequence along the conveying direction of the product 2 to be processed.

[0034] Specifically, the conveying and guiding assembly 3 includes a first guide group, a second guide group, and a conveying group arranged sequentially. Both the first and second guide groups include guide baffles 9 symmetrically arranged front and rear. A mounting plate is welded to the bottom of each guide baffle 9, and the mounting plate is bolted to the support frame 1. A channel 10 is formed between the two guide baffles 9. The width of the channel 10 gradually decreases along the direction of movement of the product 2 to be processed. The outlet of the channel 10 of the first guide group is located at the inlet of the channel 10 of the second guide group. The product 2 to be processed first undergoes preliminary guidance through the channel 10 of the first guide group, and then enters the channel 10 of the second guide group for further guidance, ensuring the accuracy of the conveying direction.

[0035] Specifically, a cover plate 11 is fastened to the top of both the front and rear guide baffles 9. Two inverted L-shaped locking blocks 12 are welded to the upper side walls of the guide baffles 9. The locking blocks 12 and the upper surface of the guide baffles 9 form a locking groove 13. A longitudinal locking strip 14 is welded to the upper surface of the cover plate 11. The two ends of the locking strip 14 extend out of the side walls of the cover plate 11 and are engaged in the locking groove 13. Through the cooperation of the locking strip 14 and the locking groove 13, the cover plate 11 and the guide baffles 9 are fastened together. The cover plate 11 can prevent external dust and other debris from entering the channel 10. A handle 15 is welded to the top of the cover plate 11 to facilitate the installation and removal of the cover plate 11.

[0036] Specifically, the conveying assembly includes a set of symmetrical guide wheels 16, with a gap between the two guide wheels 16 for the product 2 to pass through. The sidewalls of the guide wheels 16 abut against the product 2. The support frame 1 is equipped with a drive assembly 17 connected to the guide wheels 16. The drive assembly 17 uses a motor transmission mechanism to drive the guide wheels 16 to rotate, thereby conveying the product 2 to the cutting assembly 4. The upper surface of the support frame 1 is provided with a protective cover 18 covering the outer sidewall of the guide wheels 16, which protects the guide wheels 16 and ensures safety. In this embodiment, the upper surface of the support frame 1 is provided with a longitudinal adjustment waist hole. The drive assembly 17 is detachably fixed to the support frame 1 through bolts on the adjustment waist hole. The gap between the two guide wheels 16 can be adjusted by adjusting the connection position of the drive assembly 17 and the adjustment waist hole.

[0037] Specifically, the cutting assembly 4 includes a mounting base 5 bolted to the support frame 1. A top base 20 is mounted on the upper surface of the mounting base 5 via two front and rear fixing rods 19. A telescopic assembly 8 is bolted to the front and rear sides of the upper surface of the top base 20. The telescopic assembly 8 is a cylinder, and its telescopic end passes through the top base 20 and is fixedly connected to a blade holder 21 by bolts. An upper cutting blade 6 is bolted to the lower part of the blade holder 21. The upper cutting blade 6 has an inverted V-shaped structure. A lower cutting blade 7 is bolted to the upper surface of the mounting base 5 and cooperates with the upper cutting blade 6. Guide sleeves 22 are welded to the front and rear sides of the blade holder 21 and are slidably connected to the side walls of the fixing rods 19. When the telescopic assembly 8 moves the blade holder 21 up and down, the guide sleeves 22 slide along the fixing rods 19 to ensure the stability of the movement of the upper cutting blade 6.

[0038] During operation, the product to be processed 2 is guided sequentially through the channels 10 of the first guide group and the second guide group, and then enters the space between the two guide wheels 16 of the conveying group. Driven by the drive component 17, the guide wheels 16 rotate and convey the product to be processed 2 between the upper cutting blade 6 and the lower cutting blade 7 of the cutting component 4. The telescopic component 8 drives the blade holder 21 to move downward, and the upper cutting blade 6 and the lower cutting blade 7 cooperate to cut the product to be processed 2. After the cutting is completed, the telescopic component 8 drives the blade holder 21 to move upward and reset, completing one cutting process.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
