[0026] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0027] refer to Figures 1 to 10 The present embodiment provides an upper plate positioning and adjustment mechanism of a plush knitting machine, comprising a knitting machine frame 1, a plurality of knitting machine support rods 2 arranged on the knitting machine frame 1, a knitting machine bracket 3 arranged on the top of the knitting machine support rod 2, a knitting machine support panel 4 fixedly arranged on the bottom surface of the knitting machine bracket 3, a knitting machine adjustment disk 5 rotatably arranged between the knitting machine support panel 4 and the knitting machine bracket 3, a slide groove 6 arranged at four corners of the knitting machine adjustment disk 5, a slider 7 slidably arranged in the slide groove 6, four straight notches 8 arranged on the knitting machine adjustment disk 5, a driving cylinder 9 for driving the knitting machine adjustment disk 5 to rotate, a sliding wheel 10 arranged on the top of the slider 7 and slidably connected to the straight notch 8, and a positioning panel 11 rotatably arranged on the side of the slider 7 away from the sliding wheel 10, the driving cylinder 9 is arranged between the knitting machine adjustment disk 5 and the knitting machine bracket 3, hinged columns 12 are arranged on both sides of the top of the positioning panel 11, and a first spring 13 is arranged between adjacent positioning panels 11.

[0028] A slide rail conveying mechanism 14 is provided at intervals on the outer bottom of the positioning panel 11 . A moving block 15 is slidably connected inside the slide rail conveying mechanism 14 . An extension block 16 is connected to the bottom of the moving block 15 . A first guide roller 17 is provided on the extension block 16 .

[0029] Put the knitting machine support rod 2 into the top of the knitting machine frame 1 and lock it with external bolts (not shown in the figure). After completion, the driving cylinder 9 drives the knitting machine adjusting disk 5 to rotate. Since the slide groove 6 on the knitting machine adjusting disk 5 extends from the position close to the outer edge to the center of the knitting machine adjusting disk 5, the sliding wheel 10 on the top of the slider 7 is slidably connected with the slide groove 6. During the rotation of the knitting machine adjusting disk 5, the slide groove 6 drives each slider 7 to move to the center of the knitting machine adjusting disk 5. The slider 7 drives the bottom positioning panel 11 to move to the position of the upper disk 100. The first guide roller 17 on the bottom extension block 16 contacts the outer side of the bottom surface of the upper disk 100. The bottom extension block 16 can provide auxiliary support for the upper disk 100. When it is necessary to push the upper disk 100 away from the central axis of the knitting machine frame 1, the top surface of the extension block 16 is in contact with the upper disk 100. The disks 100 are spaced apart at a certain distance, and the first guide roller 17 on the extension block 16 can assist in pushing the upper disk 100, so that the upper disk 100 can be conveniently and quickly moved manually. When the upper disk 100 needs to return to the central axis of the knitting machine frame 1, the extension block 16 can be removed and pulled out from the moving block 15 first, and then the knitting machine adjusting disk 5 can be driven to rotate continuously through the driving cylinder 9. The inner side of the knitting machine adjusting disk 5 drives the positioning panel 11 to move toward the middle through the slider 7. When the positioning panel 11 moves, the middle position fits the outer side of the upper disk 100. Since the positioning panels 11 are connected by the first spring 13, the positioning panel 11 will fit the outer circular surface of the upper disk 100, so that the upper disk 100 is aligned with the central axis of the knitting machine frame 1. After completion, the knitting machine support rod 2 and the knitting machine bracket 3 can be removed to facilitate the quick adjustment of the upper disk 100.

[0030] The first guide roller 17 is arranged so that when the top surface of the extension block 16 is located at the bottom surface of the upper plate 100, the first guide roller 17 contacts the bottom surface of the upper plate 100, and the upper plate 100 is placed on the top surface of the first guide roller 17, which is convenient for the operator to manually push the upper plate 100 for adjustment.

[0031] The thickness of the extension block 16 gradually increases from the side close to the knitting machine adjusting disk 5 to the side far away from the knitting machine adjusting disk 5, which is conducive to the extension block 16 entering the bottom surface of the upper disk 100.

[0032] The moving blocks 15 are rotatably connected with a second guide roller 18. When the extension block 16 moves toward the middle, the first guide roller 17 at the bottom contacts the bottom surface of the upper plate 100, and the second guide roller 18 at the bottom of the moving block 15 contacts the outer side of the upper plate 100, which is beneficial for the operator to manually rotate the upper plate 100 and reduce the resistance of the upper plate 100 during rotation.

[0033] The side of the slide rail conveying mechanism 14 away from the positioning panel 11 is provided with an adjusting bolt 19 , and a second spring 20 is provided between the adjusting bolt 19 and the moving block 15 .

[0034] The adjusting bolt 19 is set. When there is no need to move or rotate the upper plate 100, the adjusting bolt 19 is loosened. Under the action of the second spring 20, the moving block 15 and the extending block 16 will move out of the bottom surface of the upper plate 100, and the first guide roller 17 and the second guide roller 18 will not contact the upper plate 100. When the knitting machine adjusting plate 5 is driven to rotate by the driving cylinder 9, the positioning panel 11 can quickly reposition the central axis of the upper plate 100.

[0035] A debugging assembly 21 is provided on one lateral side of the knitting machine frame 1, and the debugging assembly 21 includes a guide shaft 201 rotatably arranged on the knitting machine frame 1, a first mechanical swing arm 202 rotatably arranged outside the guide shaft 201, a second mechanical swing arm 203 rotatably arranged on the knitting machine frame 1 and spaced apart from the first mechanical swing arm 202, a motor 204 for driving the second mechanical swing arm 203 to rotate, a third mechanical swing arm 205 rotatably arranged between the first mechanical swing arm 202 and the second mechanical swing arm 203, an upper extension 206 arranged on a side of the first mechanical swing arm 202 away from the third mechanical swing arm 205, a shielding cover 207 fixedly arranged on the top of the guide shaft 201, a positioning column 208 slidably arranged in the upper extension 206, a slot 209 arranged in the upper extension 206, an outer ring 210 arranged on a side of the positioning column 208 close to the shielding cover 207, and a A compression spring 211 is provided between the slots 209, and a rubber right-angle block 212 is rotatably provided on the side of the positioning column 208 close to the shielding cover 207, and the rubber right-angle block 212 has an arc-shaped fitting surface. A torsion spring 213 is connected to the rubber right-angle block 212 and the positioning column 208. The shielding cover 207 is away from the guide shaft 201. An arc-shaped raised plate is provided on the side, and a middle hole 214 for the rubber right-angle block 212 to pass through is provided in the arc-shaped raised plate. A supporting leg 215 is provided on the outside of the guide shaft 201. The arc-shaped fitting surface of the rubber right-angle block 212 extends toward the side gradually close to the positioning column 208 to form an arc 121. The arc 121 part is a curve extending toward the hinged part of the rubber right-angle block 212 and the positioning column 208, and does not contact the outer plate. The arc-shaped raised plate is spaced apart from the upper plate 100, and the arc-shaped fitting surface is in contact with the upper plate 100 away from the arc 121.

[0036] Before use, the support leg 215 is placed on the top surface of the knitting machine frame 1, and then the upper extension part 206 is placed on the outside of the upper disk 100. When the upper disk 100 needs to be rotated, the motor 204 drives the second mechanical swing arm 203 to rotate, and the second mechanical swing arm 203 drives the first mechanical swing arm 202 to rotate back and forth through the third mechanical swing arm 205. The first mechanical swing arm 202 drives the upper extension part 206 to rotate forward. During the rotation process, the arc-shaped protruding plate on one side of the shielding cover 207 contacts the position of the non-rubber right-angle block 212 on one side of the positioning column 208. As the first mechanical swing arm 202 continues to rotate, the upper extension part 206 leaves the arc-shaped protruding plate on one side of the shielding cover 207. Under the action of the compression spring 211, the positioning column 208 moves from the slot 209 in the upper extension part 206 toward the upper disk 100. The side of the positioning column 208 that is not restricted by the arc-shaped protruding plate on the side of the shielding cover 207 will pop out and contact the upper disk 100. As the first mechanical swing arm 202 continues to rotate, the rubber The rubber right-angle block 212 contacts the upper plate 100 and pushes the upper plate 100 to rotate 5°-15°. After completion, the first mechanical swing arm 202 rotates backward. Since the rubber right-angle block 212 is hinged with the positioning column 208, the rubber right-angle block 212 rotates 90° under the action of friction, and the rear end of the rubber right-angle block 212 gradually extends close to the positioning column 208. After the rubber right-angle block 212 rotates, the arc line 121 part will no longer continue to contact the upper plate 100 until it moves to the original position. Since there is a middle hole 214 on the arc-shaped raised plate on one side of the shielding cover 207, the rubber right-angle block 212 will return to its original position under the action of the torsion spring 213. In the original positioning and adjustment process of the upper plate 100, it is necessary to manually rotate the position of the upper plate 100 slowly. By controlling the rotation of the motor 204, the upper plate 100 can be slowly rotated, stopped, and then rotated until it rotates 360°. The operator does not need to manually rotate the upper plate 100, and it is easier for the operator to observe and adjust the upper plate 100.
