Description

Technical Field

[0001] This utility model relates to the field of leather processing, specifically to an equidistant cutting device for leather products. Background Technology

[0002] Leather is tanned hide made from the skins of animals such as cows, sheep, and pigs after the hair has been removed and the hides have undergone physical and chemical processing methods such as tanning. It is characterized by its softness, toughness, and durability, and can be used to make various leather products, such as leather shoes, bags, clothing, and sofas. These products not only provide warmth, water resistance, and windproofing, but are also very fashionable and widely used in daily life. Leather can be classified into natural leather and substitute leather, the latter including reconstituted leather, artificial leather, and synthetic leather. They each have their own characteristics in appearance and performance, meeting the needs of different fields. Leather processing requires the use of cutting equipment for trimming.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of an equidistant cutting device for leather products, comprising a conveyor belt 1, conveyor belt side plates 101 connected to both ends of the conveyor belt 1, support frames 2 fixedly connected to one side of the upper end of each of the two conveyor belt side plates 101, an unwinding roller 3 rotatably connected between the upper ends of the two support frames 2, a leather roll 301 wound on the unwinding roller 3, vertical slots 201 provided in the middle of the upper ends of each of the two conveyor belt side plates 101, a support base 4 fixedly connected to the upper end of the front end face of the front conveyor belt side plate 101, a servo motor 401 fixedly connected to the upper end of the support base 4, a transmission component 402 fixedly connected to the output end of the servo motor 401, and a rotating shaft 30 fixedly connected to the middle of the unwinding roller 3. 2. The front and rear ends of the rotating shaft 302 extend to the outside through the vertical slots 201 on the two conveyor belt side plates 101 respectively. A rectangular insert 303 is fixedly connected to the front end of the rotating shaft 302 after it extends out of the front end face of the conveyor belt side plate 101. A rectangular slot 403 is provided on the transmission component 402. The upper end of the rectangular slot 403 is connected to the upper end face of the transmission component 402. The rectangular insert 303 on the rotating shaft 302 is inserted into the rectangular slot 403. The transmission component 402 is driven by the servo motor 401, which in turn drives the unwinding roller 3 to rotate. The rotation angle of the unwinding roller 3 is controlled by the servo motor 401 each time, so that the leather roll 301 on the unwinding roller 3 is unwound downward at equal intervals.

[0024] Please see Figure 1-3 A cutting seat 203 is fixedly connected to one side of the middle between the two support frames 2, and a transverse support plate 5 is fixedly connected to the other side of the middle between the two support frames 2. A strip-shaped blade holder 501 is provided between one side of the transverse support plate 5 and the cutting seat 203. A cutting blade 502 is fixedly connected to the middle of one side of the strip-shaped blade holder 501. A vertical guide plate 204 is fixedly connected between the two support frames 2 and at the upper end of one side of the cutting seat 203. A guide roller 206 is rotatably connected to the upper end of the vertical guide plate 204. After being unwound, the leather falls to the cutting seat after being guided by the guide roller 206 and the vertical guide plate 204. Between the cutting seat 203 and the cutting blade 502, an electrically controlled telescopic rod 504 is fixedly connected to the middle of one side of the transverse support plate 5. The telescopic end of the electrically controlled telescopic rod 504 passes through the transverse support plate 5 and is fixedly connected to the middle of one side of the strip-shaped blade holder 501. The electrically controlled telescopic rod 504 pushes the cutting seat 203 to move, causing the cutting blade 502 to move and cut the leather. An arc-shaped guide plate 205 is fixedly connected to the lower middle of the two support frames 2. The cut leather falls and is guided by the arc-shaped guide plate 205 to the conveyor belt 1. The conveyor belt 1 transports the cut leather to the subsequent processing steps.

[0025] Please see Figure 1-3Both conveyor belt side plates 101 are provided with strip-shaped limiting grooves 202 in the middle. Both ends of the strip-shaped knife holder 501 are fixedly connected with rectangular sliders 503. The rectangular sliders 503 at the front and rear ends of the strip-shaped knife holder 501 are respectively inserted into the strip-shaped limiting grooves 202 in the middle of the two conveyor belt side plates 101. When the electrically controlled telescopic rod 504 pushes the cutting seat 203 to move, the rectangular sliders 503 slide along the inside of the strip-shaped limiting grooves 202 to ensure the stability of the movement of the strip-shaped knife holder 501.

[0026] Working Principle: During operation, the servo motor 401 starts, driving the transmission component 402 to rotate. Since the rectangular insert 303 on the rotating shaft 302 is inserted into the rectangular slot 403 of the transmission component 402, the transmission component 402 drives the unwinding roller 3 to rotate, thereby gradually unwinding the leather roll 301. After being guided by the guide roller 206 and the vertical guide plate 204, the leather falls flat onto the cutting seat 203. At this time, the electrically controlled telescopic rod 504 starts, and its telescopic end pushes the strip-shaped cutter holder 501 to slide along the strip-shaped limiting groove 202, thereby driving the cutting blade 502 to cut the leather. After cutting, the leather falls and is guided by the arc-shaped guide plate 205 onto the conveyor belt 1, which then transports it to the subsequent processing steps. By controlling the rotation angle of the unwinding roller 3 through the servo motor 401, equidistant unwinding and cutting of the leather can be achieved. The entire process is highly automated, requiring no manual assistance and greatly improving production efficiency.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
