The second mounting plate 112 is located on the right side of the frame 110. Two sets of first guide rollers 111 are rotatably connected on both sides of the interior of the frame 110. Dust removal mechanisms 4 are set on both sides of the top of the frame 110. Two sets of support plates 113 are welded on the left and right sides of the top of the second mounting plate 112.

[0045] In this solution, the staff transports several groups of leather rollers 103 to the first L-shaped plate 102, loads them through the feeding mechanism 2, and sequentially transfers several groups of leather rollers 103 to the second L-shaped plate 219. Subsequently, they are clamped and installed through the clamping mechanism 3. The leather on the leather roller 103 passes through the first guide roller 111 and the second guide roller 114 in sequence, and the leather is collected by the collecting roller 128.

The device is integrated and meets the needs of the staff.

[0046] Example 2

[0047] Please refer to Figure 5-7As shown, the feeding mechanism 2 includes a first fixing member 201, and the first fixing member 201, the second fixing member 202, the third fixing member 203, the fourth fixing member 204 and the fifth fixing member 205 are welded on both sides of the top of the first mounting plate 109. The top of the first fixing member 201 is rotatably connected to the first rotating arm 206, and the two groups of third fixing members 203 are rotatably connected to the rotating rod 208. The two ends of the outer surface of the rotating rod 208 are fixedly connected to the turntable 209, and the inner parts of the two groups of turntables 209 are rotatably connected to the third connecting rod 220. The two ends of the third connecting rod 220 are rotatably connected to the triangle 210 and the fourth rotating arm 213. The other end of the first rotating arm 206 is rotatably connected to the middle part of the triangle 210, and the inner side of the second fixing member 202 is rotatably connected to the second rotating arm 207. The inner parts of the second rotating arms 207 on both sides are rotatably connected to the first connecting rod 211. The outer surfaces of a connecting rod 211 are rotatably connected to the third rotating arm 212 at both ends, the other end of the triangle 210 is rotatably connected to the middle of the third rotating arm 212, and the inner side of the fourth fixing member 204 is rotatably connected to the sixth rotating arm 217, the other end of the sixth rotating arm 217 is rotatably connected to the fourth rotating arm 213, and the outer side of the fifth fixing member 205 is rotatably connected to the fifth rotating arm 216, the other end of the fifth rotating arm 216 is rotatably connected to the outer side of the loading member 215, the inner side of the loading members 215 on both sides is rotatably connected to the second connecting rod 214, the other end of the fourth rotating arm 213 is rotatably connected to the outside of the second connecting rod 214, the outer side of the front third fixing member 203 is installed with a first servo motor 218, one end of the rotating rod 208 is fixedly connected to the output end of the first servo motor 218, and the top ends of the two groups of third rotating arms 212 are fixedly connected to the second L-shaped plate 219.

[0048] Please refer to Figure 4 As shown, both ends of the leather roller 103 are provided with a card slot 104, and mounting parts 105 are installed at symmetrical positions on the front and rear sides of the first L-shaped plate 102. The outer side of the mounting part 105 is fixedly connected to an electric push rod 106, and the output end of the electric push rod 106 is fixedly connected to a fixed plate 107. The inner side of the fixed plate 107 is fixedly connected to a first card block 108 that is adapted to the card slot 104.

[0049] In this solution, the working principle of the feeding mechanism 2 is as follows: the output end of the first servo motor 218 drives the rotating rod 208 and the two sets of turntables 209 to rotate as a whole, so that the triangle 210 rotates, driving the first rotating arm 206, the second rotating arm 207 and the third rotating arm 212 to rotate, and at the same time, when the turntable 209 rotates, it drives the fourth rotating arm 213 to rotate, so that the fifth rotating arm 216 and the sixth rotating arm 217 rotate. Therefore, when the output end of the first servo motor 218 drives the turntable 209 to rotate counterclockwise, the spacing between the two sets of feeding parts 215 is greater than the width of the second L-shaped plate 219. The feeding part 215 can transfer the leather roller 103 to the inside of the second L-shaped plate 219, and the installation position of the clamping mechanism 3 is in the middle and upper end of the third rotating arm 212. This installation method of the clamping mechanism 3 will not interfere with the rotation and feeding of the feeding part 215.

[0050] It is worth mentioning here that after a group of leather rollers 103 are loaded, the upper leather roller 103 is clamped inside the first L-shaped plate 102. The clamping method is to extend the output end of the electric push rod 106 to drive the first clamping blocks 108 on both sides to be clamped in the clamping groove 104 of the leather roller 103. The reason for doing this is that when the leather roller 103 that has been loaded is fed subsequently, the height of the leather roller 103 can also be changed by the loading mechanism 2 during the feeding period, and the loading part 215 will no longer transport the leather roller 103 to the inside of the second L-shaped plate 219, which also realizes the adjustment of the tension of the leather material during the transportation process, thereby improving the ingenuity of the design.

[0051] Example 3

[0052] Please refer to Figure 7 and Figure 8 As shown, the clamping mechanism 3 includes a threaded rod 301, a guide rod 302 and a movable member 305. The threaded rod 301 is rotatably connected to the inside of the two sets of third rotating arms 212. The guide rod 302 is fixedly connected to the inside of the two sets of third rotating arms 212. The threads opened at both ends of the threaded rod 301 have opposite rotation directions, and the movable member 305 is provided with two groups and is respectively threadedly connected to the two ends of the outer surface of the threaded rod 301. The bottom end of the movable member 305 is installed with an electric lifting rod 306. The output end of the electric lifting rod 306 passes through the bottom wall of the movable member 305 and is fixedly connected to the support member 307. The internal rotation of the support member 307 is connected to a rotating shaft, and the side of the rotating shafts on both sides that are close to each other is connected to a second clamping block 309, and a feeding motor 308 is installed on the outside of one group of support members 307, one end of one group of rotating shafts is fixedly connected to the output end of the feeding motor 308, and connecting members 303 are fixedly installed on both ends of the guide rod 302, the connecting members 303 are rotatably connected to the threaded rod 301, and a second servo motor 304 is installed on the outside of one group of connecting members 303, and one end of the threaded rod 301 is fixedly connected to the output end of the second servo motor 304.

[0053] In this solution, the working principle of the clamping mechanism 3 is as follows: after the leather roller 103 is transferred to the inside of the second L-shaped plate 219, the two groups of movable parts 305 are driven to approach each other through the output end of the second servo motor 304, and the second clamping blocks 309 on both sides are stuck in the clamping grooves 104 at both ends of the leather roller 103, and the support part 307 is driven upward by the output end of the electric lifting rod 306 to prevent the bottom support plate of the second L-shaped plate 219 from interfering with the feeding of the leather roller 103, and then the leather roller 103 is driven to rotate by the output end of the feeding motor 308 to realize feeding.

[0054] Example 4

[0055] Please refer to Figure 9 and Figure 10 As shown, the dust removal mechanism 4 includes a top plate 401, a linear slide rail 402 and a slide groove 403 are provided on the top plate 401, the inner top of the slide groove 403 is connected to the lifting plate 405 through a first spring 404, and limited slide grooves are provided on both sides of the interior of the slide groove 403. Both sides of the lifting plate 405 are slidably connected to the interior of the limited slide groove, and the lifting plate 405 is provided with a mounting groove 406. The interior of the mounting groove 406 is slidably connected to a slide rod 407, one end of the slide rod 407 is fixedly installed with a limited block 408, and the other end of the slide rod 407 is connected to a first wedge block 410, and the outer surface of the slide rod 407 is sleeved with a second spring 409, one end of the second spring 409 is fixedly connected to the inner wall of the mounting groove 406, and the other end of the second spring 409 is fixedly connected to the outer side of the first wedge block 410, and the lifting plate 405 is fixedly connected to a support plate 414, and the bottom ends of the two groups of support plates 414 are installed with dust removal plates 415.

[0056] Please refer to Figure 10 As shown, a sliding member 412 is slidably connected inside the linear slide rail 402 , a fixing rod 413 is fixedly mounted on the sliding member 412 , and a second wedge block 411 is also fixedly connected to the top plate 401 .

[0057] In this solution, the working principle of the dust removal mechanism 4 is as follows: the linear slide rail 402 drives the sliding member 412 and the fixed rod 413 to move upward as a whole, and the fixed rod 413 supports the bottom of the first wedge block 410, so that the lifting plate 405 also moves upward, and the first spring 404 is in a contracted state. When the inclined surface of the first wedge block 410 contacts the inclined surface of the second wedge block 411, the second spring 409 contracts, and the first wedge block 410 retracts into the interior of the mounting groove 406, so that the fixed rod 413 no longer supports the bottom of the first wedge block 410. Under the action of the first spring 404 restoring its deformation, the lifting plate 405 moves downward rapidly, and the dust removal plate 415 slaps the surface of the leather downward to shake off the dust remaining on the surface of the leather to achieve dust removal; the rear linear slide rail 402 drives the sliding member 412 and the fixed rod 413 to move downward as a whole, and the fixed rod 413 moves downward and contacts the inclined surface of the first wedge block 410, which can also make the first wedge block 410 retract into the interior of the installation groove 406, and the fixed rod 413 can continue to move downward to the bottom of the first wedge block 410 to achieve the reset state.
