[0002] In the industrial production of leather products, such as bags, leather goods, and footwear, the processes involved, including cutting, printing, embossing, and gluing, all require processing individual sheets of leather. However, leather sheets purchased in bulk are often bundled and stacked. These bundled and stacked leather sheets are usually obtained through heat cutting, making their edges prone to sticking together. Furthermore, the pressure between the leather sheets during transportation can also cause them to stick together, making them unsuitable for direct entry into subsequent automated equipment.

[0003] Traditionally, leather is paginated manually; however, this method is not only time-consuming but also prone to damaging the leather. Therefore, there is a need to design a device that can automatically paginate leather, working in conjunction with other automated equipment to improve production efficiency. Utility Model Content

[0026] The technical solution of this utility model will be described in detail below through specific embodiments.

[0027] like Figure 1-9 As shown, a schematic diagram of the overall and partial structure of the leather collating machine, as well as a diagram of its working state, are presented.

[0028] The leather collating machine includes a feeding conveyor belt 1, a V-shaped collating mechanism 2, and a discharging conveyor belt 3 that are connected in sequence. The V-shaped collating mechanism 2 includes a V-shaped conveyor belt 201, which is wound around a first fixed roller 202, a second fixed roller 203, a tension roller 204, and a movable roller 205 to form a V-shaped structure.

[0029] On the machine body, at the positions of the feeding conveyor belt 1 and the unloading conveyor belt 3, there are feeding ports 4 and unloading ports 5 respectively. The feeding conveyor belt 1 and the unloading conveyor belt 3 extend from the feeding ports 4 and the unloading ports 5 to the outside of the machine body to facilitate feeding and unloading.

[0030] In this embodiment, there are 4 sets of V-shaped paging mechanisms 2, which are distributed in pairs on both sides of the machine body. In other embodiments, the number of V-shaped paging mechanisms 2 can be 1 set, 2 sets, 3 sets, 5 sets, or any other number, as long as it can complete the paging of the entire bundle of leather.

[0031] From top to bottom, the equipment body consists of four V-shaped paging mechanisms: the first group, the second group, the third group, and the fourth group. The first and third groups, as well as the second and fourth groups, are located on opposite sides of the equipment structure. An intermediate conveyor belt 6 is positioned between each pair of V-shaped paging mechanisms. One end of the intermediate conveyor belt 6 abuts against the second fixed roller 203 of the preceding V-shaped paging mechanism, and the other end abuts against the movable roller 205 of the following V-shaped paging mechanism.

[0032] To ensure the continuity of movement, the loading conveyor belt 1 and the unloading conveyor belt 3 are set to be horizontal, and the middle conveyor belt 6 is consistent with the unloading conveying direction of the V-shaped conveyor belt 201 in the previous V-shaped paging mechanism.

[0033] The first, second, third, and fourth V-shaped paging mechanisms have the same structure.

[0034] For example, in the first set of V-shaped paging mechanisms, the first fixed roller 202 and the second fixed roller 203 are rotatably mounted on the machine body via rolling bearings. The tension roller 204 is located on one side between the first fixed roller 202 and the second fixed roller 203, forming the bottom of the V-shaped structure. The movable roller 205 is located inside the V-shaped structure and above the tension roller 204. The movable roller 205 abuts against the end of the feeding conveyor belt 1. The tension roller 204 is movably mounted on the machine body via a telescopic mechanism. Specifically, the telescopic mechanism is a pneumatic spring 7, and the telescopic direction of the pneumatic spring 7 is consistent with the setting direction of the feeding conveyor belt 1. The second fixed roller 203 abuts against the beginning of the intermediate conveyor belt 6.

[0035] A baffle 8 is installed on the side of the first V-shaped paging mechanism. The baffle 8 is fixedly connected to the first fixed roller 202, the second fixed roller 203, and the bottom of the V-shaped structure on the machine body. The baffle 8 has a waist-shaped hole 9, the direction of which is consistent with the setting direction of the feeding conveyor belt 1. One end of the pneumatic spring 7 passes through the waist-shaped hole 9 and is connected to the tension roller 204, and the other end is installed on the baffle 8.

[0036] The baffle 8 has a triangular structure. A support rod 10 is fixedly installed on the machine body below the bottom of the V-shaped paging mechanism 2. The baffle 8 is fixedly connected to the support rod 10.

[0037] The feeding conveyor belt 1 is wound around the feeding transmission roller 101 and driven by the first motor 102, which is installed inside the equipment body. Specifically, a feeding transmission gear 103 is provided at one end of the feeding transmission roller 101, and the output shaft of the first motor 102 is connected to the feeding transmission gear 103 by meshing with the first synchronous belt 104.

[0038] The first V-shaped paging mechanism and the intermediate conveyor belt 6 are driven by the second motor 301. Specifically, the intermediate conveyor belt 6 is wound around the intermediate transmission roller, and an intermediate transmission gear 302 is provided at one end of the intermediate transmission roller. A first gear 303 is provided at one end of the second fixed roller 203 of the first V-shaped paging mechanism. The output shaft of the second motor 301, the intermediate transmission gear 302 and the first gear 303 are connected by meshing transmission through the second synchronous belt 304.

[0039] The connection between the second group of V-shaped paging mechanisms, the third group of V-shaped paging mechanisms and their respective intermediate transmission rollers is the same as above, wherein a third motor 11 and a fourth motor 12 are respectively provided to drive the operation of their respective mechanisms.

[0040] The fourth V-shaped paging mechanism and the feeding conveyor belt 3 are driven by the fifth motor 401. Specifically, the feeding conveyor belt 3 is wound around the feeding transmission roller, and a feeding transmission gear 402 is provided at the first end of the feeding transmission roller. In the fourth V-shaped paging mechanism, a fourth gear 403 is provided at one end of the second fixed roller 203. The output shaft of the fifth motor 401, the feeding transmission gear 402, and the fourth gear 403 are connected by a fifth synchronous belt 404.

[0041] The working process of this leather collating machine is as follows: When the machine is turned on, the first motor 102 to the fifth motor 401 rotate, driving the feeding conveyor belt 1, the V-shaped piecing mechanism 2 and the unloading conveyor belt 3 to rotate and enter the working state. The entire bundle of leather sheets is manually placed onto the feeding conveyor belt 1 through the feeding port 4. The feeding conveyor belt 1 drives the leather sheets to move into the first set of V-shaped paging mechanisms. When the leather sheets enter the gap between the feeding conveyor belt 1 and the movable roller 205, they will squeeze the movable roller 205 to move towards the bottom of the V-shaped structure, causing the movable roller 205 to move away from the feeding conveyor belt 1. At this time, the length of the conveyor belt inside the V-shaped structure is stretched. Correspondingly, the conveyor belt outside the V-shaped structure pulls the tension roller 204 and the pneumatic spring 7 to contract along the waist-shaped hole 9 towards the top of the V-shaped structure to maintain the circumference of the V-shaped conveyor belt 201 fixed. Due to the limitation of the length of the waist-shaped hole 9, the movable roller 205 will not open excessively. Utilizing the friction between the leather and the feeding conveyor belt 1, between the leather and the V-shaped conveyor belt 201, and between the leather and the movable roller 205, the leather at different positions passes through the gap between the feeding conveyor belt 1 and the movable roller 205 in sequence, which can separate the whole bundle of sticky leather sheets and complete the first pageing. After the first pageing, the leather sheets are transported along the V-shaped conveyor belt 201 to the middle conveyor belt 6 and enter the second set of V-shaped pageing mechanisms. In the second paging mechanism, the leather sheets that were not separated after the first paging can be paginated again, thus performing four paging processes. Finally, the completed leather sheet is output along the feeding conveyor belt 3 through the feeding port 5.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
