[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-6 As shown, a slitting device for belt processing includes a base 1, a feeding structure 4 is fixedly installed at the edge of the upper left part of the base 1, a leather limiting component 2 is fixedly installed at the upper left part of the base 1 to the right of the feeding structure 4, and a slitting and cutting component 3 is fixedly installed at the upper right part of the base 1.

[0030] The leather limiting assembly 2 includes two vertical plates 21. The lower ends of the two vertical plates 21 are fixedly installed on the upper left side of the base 1, located to the right of the feeding structure 4. A guide shaft 22 is fixedly installed on the top of the opposite sides of the two vertical plates 21. The front and rear parts of the outer wall of the guide shaft 22 are movably sleeved with a limiting plate 23.

[0031] The slitting and cutting assembly 3 includes two fixed plates 31. The lower ends of the two fixed plates 31 are fixedly installed on the upper right side of the base 1, located to the right of the guide shaft 22. The upper and lower parts of the two fixed plates 31 are movably connected to the slitting mechanism 32 on opposite sides. A processing table 33 is fixedly installed on the upper right side of the base 1. Support rods 34 are fixedly installed on the front and rear parts of the upper end of the processing table 33. A top plate 35 is fixedly installed on the upper end of the two support rods 34. A movable plate 36 is slidably connected to the outer side of the two support rods 34. A cutter 37 is fixedly installed in the middle of the lower end of the movable plate 36. A cutting groove matching the cutter 37 is opened in the middle of the upper end of the processing table 33.

[0032] The leather limiting component 2 allows for flexible adjustment of the distance between the two limiting discs 23 according to the actual needs of belt processing, precisely limiting the position of the leather and ensuring that it does not shift during processing, thus improving the accuracy and quality of slitting. The slitting and cutting component 3 can accurately divide the leather into the required strips, and the reciprocating motion of the cutter 37 can quickly and accurately cut the leather. The entire component realizes integrated slitting and cutting operations, improving the efficiency and automation of belt processing.

[0033] like Figure 3 As shown, the bottom of the two vertical plates 21 on opposite sides is rotatably connected to a bidirectional lead screw 24 that passes through the front of the front vertical plate 21. A circular plate is fixedly installed at the front end of the bidirectional lead screw 24, and sliders 25 are threadedly connected to the front and rear parts of the outer wall of the bidirectional lead screw 24.

[0034] When the leather roll is released from the feeding structure 4, the worker adjusts the distance between the two limiting discs 23 in advance according to the width of the leather. Rotating the circular plate drives the bidirectional lead screw 24 to rotate, and the two sliders 25 are connected to it by threads, which uses the two connecting plates 27 to drive the two limiting discs 23 to move closer to each other, thereby restricting the leather and preventing it from deviating when entering the slitting mechanism 32.

[0035] like Figure 3 As shown, guide rods 26 are fixedly installed on the bottom of the two vertical plates 21 on opposite sides, located below the bidirectional lead screw 24. The inner walls of the bottom of the two sliders 25 are slidably connected to the front and rear parts of the outer side of the guide rods 26.

[0036] The guide rod 26 guides the movement of the two sliders 25.

[0037] like Figure 3 As shown, a connecting plate 27 is fixedly installed at the upper middle part of each of the two sliders 25, and the upper ends of the two connecting plates 27 are fixedly connected to the bottom of the outer wall of the two limiting plates 23.

[0038] like Figure 4 As shown, the slitting mechanism 32 includes a protective cover 321 with an open right side. The front and rear ends of the protective cover 321 are fixedly installed at the edges of the two fixed plates 31 on opposite sides. The upper and lower parts of the two fixed plates 31 on opposite sides are respectively provided with a ring-cutting part 322 and a ring groove part 323 in the inner cavity of the protective cover 321. A feed chute is provided through the middle of the left side of the protective cover 321. The upper and lower parts of the inner wall of the feed chute are fixedly installed with symmetrically arranged guide plates 324. The two guide plates 324 correspond to the meshing parts of the ring-cutting part 322 and the ring groove part 323.

[0039] The worker guides the confined leather from the feed chute into the interior of the protective cover 321. Guided by two guide plates 324, the leather accurately enters between the ring-cutting section 322 and the ring groove section 323. The slitting mechanism 32 cuts the leather and discharges the slits from the right side of the protective cover 321. The worker guides the leather strips from the surface of the support guide plate onto the processing table 33. The feeding structure 4 is controlled by an external control system, which can be preset with parameters to feed leather of a specific length. The worker holds the leather strips on the right side of the base 1, the motor 38 starts, the cutter moves down and cuts multiple leather strips. Subsequently, the leather does not require worker guidance; automated processing is achieved through the cooperation of the feeding structure 4, the leather confining assembly 2, and the slitting and cutting assembly 3. The worker, located on the right side of the base 1, collects the cut leather strips.

[0040] like Figure 5 As shown, a support guide plate is fixedly installed on the upper right side of the base 1, between the protective cover 321 and the processing table 33.

[0041] like Figure 5 and Figure 6 As shown, a motor 38 is fixedly installed on the upper left side of the top plate 35, a dial 39 is fixedly installed on the output end of the motor 38, a convex notch 310 is fixedly installed on the middle right side of the dial 39, a mounting plate 311 is fixedly installed at the rear of the middle upper part of the top plate 35, a rotating shaft 312 is rotatably connected to the inner wall of the mounting plate 311, a grooved wheel 313 is fixedly sleeved on the rear of the outer wall of the rotating shaft 312, four concave arcs 314 arranged in a ring and matching the convex notch 310 are opened on the outer side of the grooved wheel 313, and a moving groove 315 is opened between the four adjacent concave arcs 314, and a dial post 316 matching the moving groove 315 is fixedly installed at the right edge of the dial 39.

[0042] The output of motor 38 drives dial 39 to rotate, and dial 316 enters the moving groove 315. The drive wheel 313 drives the rotating shaft 312 and turntable 319 to rotate intermittently by a quarter circumference. When the turntable 319 rotates, it uses the derailment drive guide sleeve 318 and moving plate 36 to move up and down, thereby realizing the intermittent reciprocating movement of cutter 37. Cutter 37 cooperates with slitting mechanism 32 and feeding structure 4 to cut the slitting leather strips into equidistant lengths.

[0043] like Figure 6 As shown, a connecting rod 317 that penetrates the top of the top plate 35 is fixedly installed at the upper middle part of the movable plate 36. A guide sleeve 318 is fixedly installed at the upper end of the connecting rod 317. A turntable 319 is fixedly installed at the right end of the rotating shaft 312. A pin matching the guide sleeve 318 is fixedly installed at the right edge of the turntable 319.

[0044] The working principle of this utility model is as follows: In use, the leather roll is fixed to the feeding structure 4, which then feeds the leather roll out. The worker adjusts the distance between the two limiting discs 23 beforehand according to the width of the leather. Rotating the circular plate causes the bidirectional lead screw 24 to rotate, and the two sliders 25, through their threaded connection, use the two connecting plates 27 to bring the two limiting discs 23 closer together, thus restricting the leather and preventing it from shifting when entering the slitting mechanism 32. The worker guides the restricted leather from the feed chute into the interior of the protective cover 321. Due to the guidance of the two guide plates 324, the leather accurately enters between the ring-cutting section 322 and the ring groove section 323. The slitting mechanism 32 cuts the leather and discharges the cut leather strips from the right side of the protective cover 321. The worker guides the leather strips from the surface of the supporting guide plate onto the processing table 33. The feeding structure 4 is controlled by an external control system, which can pre-set parameters to feed out leather of a specific length. The worker pulls the leather strip on the right side of the base 1, the motor 38 starts, the cutter moves down and cuts multiple leather strips.

[0045] Subsequently, the leather no longer requires worker guidance due to the support guide plate, and can be processed automatically using the feeding structure 4, leather limiting component 2, and slitting and cutting component 3. The worker is located on the right side of the base 1, collecting the cut leather strips.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
