Description

Technical Field

[0001] This utility model belongs to the field of sheepskin product manufacturing technology, and specifically relates to a stretching and flattening device for sheepskin product manufacturing. Background Technology

[0002] The production of sheepskin products is a complex and multi-step process, involving multiple stages from the selection of raw materials to the production of finished products. During the production process, raw hides are transformed into durable materials through tanning. Then, the sheepskins need to undergo processes such as stretching, embossing, and polishing to improve the appearance and feel of the leather, making it easier to accurately cut leather parts into the required shapes according to the design drawings.

[0003] Existing sheepskin stretching and flattening devices for sheepskin product production stretch and flatten the sheepskin by placing it in a suitable position and clamping it at the four corners with limiting clamps. A drive mechanism moves the limiting clamps clamping the sheepskin at the four corners to facilitate subsequent processing. However, in actual use, because the clamping mechanism is relatively simple, the clamping force on the sheepskin decreases after long-term use, which may affect the subsequent stretching and flattening of the sheepskin. This requires frequent replacement and adjustment of the clamping mechanism, which is troublesome and inconvenient to use. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a stretching and flattening device for sheepskin product production. This device can quickly and stably clamp the four corners of the sheepskin and move it in the opposite direction, thus quickly and efficiently stretching and flattening the sheepskin and effectively ensuring the stretching and flattening effect.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a stretching and flattening device for sheepskin product production, including a stretching seat, on which symmetrically distributed sliding frames are slidably arranged. Each sliding frame is provided with a guide rail on its upper side, and symmetrically distributed sliding seats are slidably arranged inside each guide rail. Each sliding seat is provided with a clamping seat on its upper surface, and each clamping seat is provided with a clamping frame through a driving mechanism. Each clamping frame is provided with a clamping plate on its side near the lateral center of the clamping seat. The driving mechanism is used to drive the movement of the clamping plate. Symmetrically distributed U-shaped seats are provided on the upper surface of the stretching seat, and rotating rollers are rotatably arranged inside each U-shaped seat. A frame is provided on the lower side of the stretching seat, and multiple support legs are provided on the lower surface of the frame. A rubber pad is glued and fixed to the lower surface of each support leg.

[0006] As a further improvement of this utility model, the driving mechanism includes a rotating shaft symmetrically rotatably disposed inside each clamping seat, with a rotating rod fixedly disposed at both ends of each rotating shaft, and multiple rotating shafts rotatably disposed on the outer side of each clamping seat, with a rotating rod disposed at the end of each rotating shaft away from the clamping seat, and the clamping frame rotatably connected to the adjacent rotating rods and rotating rods respectively; a worm wheel is fixedly sleeved in the middle of the outer arc surface of each rotating shaft, and a worm is rotatably disposed in the middle of each clamping seat, with the worm wheel meshing with the adjacent worm respectively; a second servo motor is disposed on the outer side of each clamping seat, and the output shaft of the second servo motor is fixed to the adjacent worm respectively through a coupling.

[0007] As a further improvement of this utility model, each guide rail is rotatably equipped with a bidirectional lead screw, and the slide is threadedly connected to the adjacent bidirectional lead screw. A servo motor is installed on the outer side of each guide rail, and the output shaft of the servo motor is threadedly connected to the adjacent bidirectional lead screw. A support is installed inside the tension seat, and adjusting lead screws are rotatably installed on both the support and the inner wall of the adjacent tension seat. The adjusting lead screws are threadedly connected to the adjacent slide frame. A dual-axis motor is installed in the middle of the support, and the output shafts of the dual-axis motors are fixed to the adjacent adjusting lead screws via couplings. As a further improvement of this utility model, anti-slip pads are glued and fixed on the side of the clamping plate near the lateral center of the clamping seat, and each anti-slip pad is provided with anti-slip protrusions.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the output shaft of the second servo motor drives the worm gear connected to it to rotate. Since the rotating rod, rotating rod, rotating shaft, rotating shaft and clamping frame can form a parallelogram structure, the clamping frames on the upper and lower sides move closer together, thereby driving the clamping plates on the upper and lower sides to move closer together to clamp and fix the four corners of the sheepskin.

[0009] Secondly, the output shaft of servo motor one drives the bidirectional lead screw connected to it to rotate. Through the threaded relationship between the bidirectional lead screw and the slide, the clamping seats on the front and rear sides move in opposite directions, so that the clamping plates on the front and rear sides move in opposite directions after clamping the sheepskin.

[0010] Third, the output shaft of the dual-axis motor drives the adjusting screw connected to it to rotate. By adjusting the thread relationship between the adjusting screw and the sliding frame, the sliding frames on the left and right sides move in opposite directions, which in turn drives the clamping seats on the left and right sides to move in opposite directions, so that the clamping plates on the left and right sides move in opposite directions after clamping the sheepskin.

[0011] Fourth, after the sheepskin is clamped by the clamping plate, the anti-slip pad is used to increase the friction between the clamping plate and the sheepskin, which can effectively prevent the clamping plate from sliding between the clamping plate and the sheepskin during the stretching and flattening process.

Detailed Implementation

[0015] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0016] like Figure 1 , 4 As shown, the device includes a stretching seat 103, on which symmetrically distributed sliding frames 201 are slidably arranged. Each sliding frame 201 has a guide rail 202 on its upper side, and each guide rail 202 has a symmetrically distributed sliding seat 203 slidably arranged inside. Each sliding seat 203 has a clamping seat 301 on its upper surface, and each clamping seat 301 has a clamping frame 306 arranged on it via a drive mechanism. Each clamping frame 306 has a clamping plate 307 on its side near the lateral center of the clamping seat 301. The drive mechanism is used to drive the movement of the clamping plate 307. A frame 101 is arranged on the lower side of the stretching seat 103, and multiple support legs 102 are arranged on the lower surface of the frame 101. Each support leg 102 has a rubber pad glued and fixed to its lower surface.

[0017] like Figure 2 , 3As shown, the drive mechanism includes a rotating shaft 302 symmetrically rotatably disposed inside each clamping seat 301. Rotating rods 303 are fixedly disposed at both ends of each rotating shaft 302. Multiple rotating shafts 304 are rotatably disposed on the outer side of each clamping seat 301. A rotating rod 305 is disposed at the end of each rotating shaft 304 away from the clamping seat 301. A clamping frame 306 is rotatably connected to adjacent rotating rods 303 and 305. A worm gear 309 is fixedly sleeved in the middle of the outer arc surface of each rotating shaft 302. A worm 310 is rotatably disposed in the middle of each clamping seat 301. The worm gear 309 meshes with adjacent worms 310. A servo motor 311 is disposed on the outer side of each clamping seat 301. The output shaft of the servo motor 311 is fixed to adjacent worms 310 via couplings.

[0018] like Figure 2 , 3 As shown, each guide rail 202 has a bidirectional lead screw rotatably installed inside, and the slide 203 is threadedly connected to the adjacent bidirectional lead screw. A servo motor 207 is installed on the outer side of each guide rail 202, and the output shaft of the servo motor 207 is threadedly connected to the adjacent bidirectional lead screw. A support 205 is installed inside the tension seat 103, and an adjusting lead screw 204 is rotatably installed on the support 205 and the inner wall of the adjacent tension seat 103. The adjusting lead screw 204 is threadedly connected to the adjacent slide frame 201. A dual-axis motor 206 is installed in the middle of the support 205, and the output shaft of the dual-axis motor 206 is fixed to the adjacent adjusting lead screw 204 by a coupling.

[0019] like Figure 1 , 2 As shown, the upper surface of the tension seat 103 is provided with symmetrically distributed U-shaped seats 104, and each U-shaped seat 104 is rotatably equipped with a rotating roller 105.

[0020] In use, the sheepskin to be stretched and flattened is placed between two rotating rollers 105. Then, the output shaft of the servo motor 311 drives the worm gear 310 connected to it to rotate. Through the meshing relationship between the worm gear 310 and the worm wheel 309, the rotating shaft 302 where the worm wheel 309 is located is driven to rotate. This causes the rotating shaft 302 to drive the rotating rod 303 at its end to rotate. Since the rotating rod 303, rotating rod 305, rotating shaft 302, rotating shaft 304 and clamping frame 306 can form a parallelogram structure, the clamping frames 306 on the upper and lower sides move closer together, thereby driving the clamping plates 307 on the upper and lower sides to move closer together to clamp and fix the four corners of the sheepskin. The output shaft of servo motor 207 drives the bidirectional lead screw connected to it to rotate. Through the threaded relationship between the bidirectional lead screw and slide 203, the clamping seats 301 on the front and rear sides move in opposite directions, so that the clamping plates 307 on the front and rear sides move in opposite directions after clamping the sheepskin. The output shaft of dual-axis motor 206 drives the adjusting lead screw 204 connected to it to rotate. Through the threaded relationship between the adjusting lead screw 204 and slide frame 201, the slide frames 201 on the left and right sides move in opposite directions, so that the clamping seats 301 on the left and right sides move in opposite directions after clamping the sheepskin. By clamping the four corners of the sheepskin and moving it in opposite directions, the sheepskin can be stretched and flattened quickly and efficiently. During the stretching process, the rotating rollers 105 on both sides can assist in stretching the sheepskin while preventing damage to the sheepskin.

[0021] According to another embodiment of the present invention, such as Figure 2 , 3 As shown, anti-slip pads 308 are glued and fixed to one side of the clamping plate 307 near the lateral center of the clamping seat 301, and each anti-slip pad 308 is provided with anti-slip protrusions. In use, after the sheepskin is clamped by the clamping plate 307, the anti-slip pads 308 increase the friction between the clamping plate 307 and the sheepskin, thereby effectively preventing slippage between the clamping plate 307 and the sheepskin during the stretching and flattening process.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
