When the first screw rod motor 15 drives the first screw rod 14 to rotate, the moving frame 3 can move along the direction of the first sliding rail 2 under the action of the screw rod and the screw nut, and when the photoelectric sensor detects that the moving frame 3 moves to the set position, the first screw rod motor 15 is immediately controlled to stop running.

[0041] Reference is made to the accompanying drawings Figure 1 , the accompanying drawings Figure 5 and the accompanying drawings Figure 6 , an absorbing and crushing cavity 16 is formed at the middle position of the platform base 1 between the two first sliding rails 2, two semicylindrical grooves 17 close to each other are formed at the upper end of the absorbing and crushing cavity 16, the distance between the top of the semicylindrical groove 17 and the upper surface of the platform base 1 is within 3 mm, two trimming slot openings 100 are formed on the upper surface of the platform base 1 and are in communication with the top of the corresponding semicylindrical groove 17, and the two trimming slot openings 100 are perpendicular to the first sliding rail 2.

[0043] The wool sweater efficient wool processing device disclosed in this embodiment is used for processing wool sweaters. An operator clamps and fixes the two shoulder positions of the flattened wool sweater through the clamping assembly 10. Then, the telescopic driving part 8 and the rotating driving device 6 are synchronously started. Under the action of the telescopic driving part 8, the clamping assembly 10 moves downwards while clamping the wool sweater. Meanwhile, the rotating driving device 6 controls the clamping assembly 10 and the shoulder of the wool sweater to rotate in the direction of approaching the wool processing slot 100 until the whole wool sweater is laid flat on the upper surface of the platform base 1.

[0044] Subsequently, the transverse screw rod transmission mechanism is started to move the moving frame 3 along the first slide rail 2 towards the wool processing slot 100. When the laid flat wool sweater passes the upper surface of the wool processing slot 100, the wool sweater lower surface floats, balls, long filament wool and the like enter the wool processing slot 100 under the action of the negative pressure in the suction cavity 16 and interact with the high-speed rotating blade 22, so that the wool sweater lower surface floats, balls, long filament wool and the like are removed by the blade 22. Meanwhile, the wool sweater lower surface sequentially passes the two wool processing slots 100, and the two high-speed rotating blades 22 rotate in opposite directions, so that the wool sweater lower surface floats, balls, long filament wool and the like are effectively removed by the two blades 22.

[0045] When the moving frame 3 moves to the other end, the telescopic driving part 8 and the rotating driving device 6 are controlled to be started and reset, so that the whole wool sweater is pulled to the vertical state. Then, the rotating driving device 6 is started in the reverse direction and the telescopic driving part 8 is continuously controlled to be elongated, so that the original upper surface of the wool sweater is laid flat on the upper surface of the platform base 1. Finally, the moving frame 3 is controlled to be moved back to the reset position. During the moving back process, the wool sweater again passes the two wool processing slots 100, and the lower surface of the wool sweater is trimmed by the high-speed rotating blade 22. Embodiment 2

[0046] Embodiment 2 discloses a wool sweater efficient wool processing device which is further designed on the basis of the technical scheme in embodiment 1. The same parts as those in embodiment 1 will not be described again.

[0047] With reference to the accompanying drawings Figure 2 , the accompanying drawings Figure 7 and the accompanying drawings Figure 8 , the side seat 26 is extended rearward or forward at the side end of the platform base 1. The second slide rail 27 extending to the end of the platform base 1 is fixed to the upper surface of the side seat 26, and the second slide rail 27 is perpendicular to the first slide rail 2. The feeding device 28 is arranged on the second slide rail 27. Meanwhile, the longitudinal screw rod transmission mechanism 29 for driving the feeding device 28 to move forward and backward is arranged on the side seat 26 and the platform base 1. The longitudinal screw rod transmission mechanism 29 is the same as the transverse screw rod transmission mechanism in structure, and the transmission directions of the two mechanisms are perpendicular to each other. Embodiment 2 will not be described again.

[0048] Specifically, the feeding device 28 comprises a moving strip seat 281 slidingly arranged on the second slide rail 27, a long-strip-shaped transmission box 282 is fixed on the upper surface of the moving strip seat 281, a second rotating rod 283 parallel to the second slide rail 27 is rotatably arranged in the transmission box 282, and an adjusting motor 288 connected with the second rotating rod 283 is arranged at the end of the transmission box 282. Two driving bevel gears 284 are symmetrically arranged on the second rotating rod 283. Two rotating shafts 285 are rotatably connected on the side of the transmission box 282 facing the moving frame 3, and the distance between the two rotating shafts 285 is not more than 30mm different from the distance between the two clamping assemblies 10. A driven bevel gear 286 meshing with the corresponding driving bevel gear 284 is arranged at the inner end of each rotating shaft 285 extending into the transmission box 282, then a support strip plate 287 is fixedly connected at the outer end of each rotating shaft 285, and the two support strip plates 287 are arranged in a staggered manner in the transverse space.

[0049] Finally, a material receiving guide groove 30 (refer to FIG. 6) is also formed on the upper surface of the platform seat 1 directly below the strip-shaped plate 9 on the side close to the second slide rail 27, and the lower end of the material receiving guide groove 30 extends out of the side end surface of the platform seat 1, so that after the woolen sweater is hung into the material receiving guide groove 30, it can slide out from the lower end of the material receiving guide groove 30. Figure 5

[0050] After the woolen sweater high-efficiency shearing device disclosed in Embodiment 2 is subjected to the shearing process in Embodiment 1, the moving frame 3 is reset and moved to one end close to the feeding device 28, during the resetting and moving process, the operator can put the woolen sweater between the two support strip plates 287, and the two support strip plates 287 are vertically arranged and aligned with the shoulder part of the woolen sweater.

[0051] When the moving frame 3 is moved to the initial position, the telescopic driving member 8 and the rotating driving device 6 are also reset, so that the woolen sweater at this time is in a vertical state and located directly above the opening of the material receiving guide groove 30. Then, current is supplied to the electromagnet 12, and then the movable clamping piece 102 is opened under the magnetic attraction between the movable clamping piece 102 and the fixed clamping piece 101, after the opening, the woolen sweater after shearing is dropped into the material receiving guide groove 30 and slides out from the lower end of the material receiving guide groove 30.

[0052] ​Subsequently, the longitudinal screw driving mechanism 29 is started, so that the two support plates 287 and the supported sweater are moved to the clamping assembly 10, until the shoulder of the sweater is aligned with the two clamping assemblies 10, then the current in the electromagnet 12 is turned off, and then under the action of the spring 105, the movable clamping piece 102 clamps and fixes the shoulder of the sweater. Finally, the adjusting motor 288 is started again to rotate the second rotating rod 283, and then under the meshing transmission of the bevel gears, the two originally vertically arranged support plates 287 rotate towards each other until they are rotated to a horizontal state, so that the support plates 287 are separated from the sweater, and the separated sweater can be subjected to the subsequent shearing process.

[0053] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
