The output end of the rotating motor 9 passes through the circular frame 5 and is fixedly connected to the side wall of one of the rotating shafts. An upper electric telescopic cylinder 10 is fixedly connected to the top of the detection platform 1. A rear plate 11 is fixedly connected to the rear side of the sliding plate 3. The output end of the upper electric telescopic cylinder 10 is fixedly connected to the side wall of the rear plate 11.

A pressing seat 14 is fixedly connected to the side away from the push plate 13, and the pressing seat 14 is arranged through the outer wall of the U-shaped plate 12. A pair of right-angle blocks 15 with inclined surfaces are provided on both sides of the top of the testing platform 1, and the inclination of the right-angle blocks 15 is the same as that of the lampshade 2, so that the push plate 13 can slide on the outer wall of the lampshade 2 to take the sweater off the lampshade 2. A discharging mechanism for pushing the U-shaped plate 12 to move is provided on the sliding plate 3; The discharging mechanism includes a double-headed electric telescopic cylinder 16, which is provided with a pair, and the double-headed electric telescopic cylinder 16 is fixedly connected to both sides of the middle position of the top of the sliding plate 3, and the two output ends of the double-headed electric telescopic cylinder 16 are fixedly connected with a rectangular plate 17, and the side walls of the U-shaped plate 12 are provided with a rectangular groove 18 adapted to the rectangular plate 17. The U-shaped plate 12 is pushed to move by inserting the rectangular plate 17 into the rectangular groove 18, so as to limit the sliding position of the U-shaped plate 12, so as to avoid that the U-shaped plate 12 moves up and down arbitrarily during the sliding process of the U-shaped plate 12 pushed by the double-headed electric telescopic cylinder 16, and the stability during the discharging process is affected. An upper spring 19 is fixedly connected between the inner side of the U-shaped plate 12 and the side wall of the push plate 13, and the upper spring 19 is used to pull the push plate 13 to reset when resetting. An adjustment mechanism for adjusting the spacing between the right-angle blocks 15 is provided on the detection table 1, and a winding mechanism for pulling the U-shaped plate 12 to reset is provided on the cross plate 6; The winding mechanism includes a pull rope 22, a pair of fixed frames 23 are fixedly connected to the bottom of the horizontal plate 6, and a winding drum 24 is rotatably connected to the inner side of the fixed frame 23. Two pairs of pull ropes 22 are provided, and each pair of pull ropes 22 is wound and fixedly connected to the outer wall of the winding drum 24. The other ends of the pull ropes 22 pass through the horizontal plate 6 and are fixedly connected to the side wall of the U-shaped plate 12. A volute spring 25 is provided on the inner side of the winding drum 24, and one end of the volute spring 25 is fixedly connected to the inner side of the winding drum 24, and the other end of the volute spring 25 is fixedly connected to the inner side of the fixed frame 23. When inspecting the sweater, the inspector first puts the sweater between a group of lampshades 2 in the middle of the inspection platform 1 for inspection, and turns on the power of the lampshade 2 so that the lampshade 2 emits a detection light, which is convenient for the inspector to detect defects on the sweater. At this time, the lampshade 2 can be rotated to drive the horizontal plate 6 and the round frame 5 to rotate inside the circular groove 4, so as to conduct a comprehensive inspection of the sweater. Then, when the sweater inspection is completed, the inspector controls the upper electric telescopic cylinder 10 to start through the control panel 36, and pushes the rear plate 11 and the sliding plate 3 to move on the inspection platform 1, so as to push the group of lampshades 2 that have been inspected to the other side of the inspection platform 1. At this time, the inspector can turn around to take a new sweater to be inspected, and at the same time control one of the reset mechanisms in the corresponding direction to start and rotate the group of lampshades 2 that have been inspected to a state perpendicular to the sliding plate 3, and then control the rotating motor 9 to drive the horizontal plate 6 to rotate, so as to flip the lampshade 2 over. Then the sliding plate 3 is pushed to the specified position, so that the other set of lampshades 2 are moved to the middle of the inspection table 1, and the roller 20 on the round frame 5 that has been inspected is moved to the side of the corresponding right-angle block 15. At this time, the inspector can put the wool sweater to be inspected on the other set of lampshades 2 for inspection. At the same time, the control panel 36 will control the double-headed electric telescopic cylinder 16 to start, and push the rectangular plate 17 into the rectangular groove 18 on the round frame 5 that has been inspected. Then, through the continued operation of the double-headed electric telescopic cylinder 16, the U-shaped plate 12 will be pushed to slide out from the horizontal plate 6, and the pull rope 22 will be pulled out to pull out the part of the pull rope 22 wound on the winding drum 24. Since the other end of the pull rope 22 is fixed on the winding drum 24, when the pull rope is pulled out The rope 22 will drive the winding drum 24 to rotate at the same time, and because one end of the spiral spring 25 is fixed to the inner wall of the winding drum 24 and the other end is fixed to the inner side of the fixed frame 23, the spiral spring 25 will be gradually compressed by the rotation of the winding drum 24, and the push plate 13 and the extrusion seat 14 will be moved by the movement of the U-shaped plate 12, and the roller 20 will be driven to roll on the inclined surface of the right-angle block 15, and then the roller 20 and the extrusion seat 14 will be gradually squeezed by the inclined surface of the right-angle block 15, so that the push plate 13 will be pushed to move along the inclined surface of the outer wall of the group of lampshades 2 that have been tested, and the middle plate 21 will be driven to move, so that the woolen sweater on the group of lampshades 2 that have been tested will be gradually taken off; At the same time, the upper spring 19 will be gradually stretched until the sweater is taken off from the group of lampshades 2 that have been tested, and then the sweater falls onto the material receiving table 35 under its own gravity, and then slides into the material box below, and then the double-headed electric telescopic cylinder 16 is controlled to move in the opposite direction to reset. During this process, the U-shaped plate 12 maintains tension under the action of the pull rope 22 and the spiral spring 25. Therefore, when resetting, the U-shaped plate 12 will move closely with the rectangular plate 17 to avoid displacement. Then the U-shaped plate 12 moves to the side of the horizontal plate 6 (it should be noted here that when the U-shaped plate 12 moves to the side of the horizontal plate 6, The spiral spring 25 is still in a compressed state, ensuring that the U-shaped plate 12 is tightly attached to the horizontal plate 6 to avoid affecting the normal insertion of the rectangular plate 17 into the rectangular groove 18 next time). At the same time, the detection of the wool sweaters on another group of lampshades 2 is completed. The detection personnel operates the control panel 36 to start the upper electric telescopic cylinder 10, and controls the rotating motor 9 and the lower electric telescopic cylinder 33 to start in turn. The above operations are repeated in reverse to complete the rapid conversion of the lampshade 2. There is no need for the detection personnel to process the wool sweaters after the detection is completed, pull them out of the lampshade 2 and put them into the material box, which saves time and effort and greatly improves the detection efficiency of the device.

[0023] In order to improve the silkiness during the operation of the device, the inner side of the extrusion seat 14 is rotatably connected to a roller 20, and the outer wall of the roller 20 is in contact with the inclined surface of the right-angle block 15. Through the setting of the roller 20, the sliding friction when the extrusion seat 14 contacts the right-angle block 15 can be converted into rolling friction, thereby improving the silkiness during the operation of the device. The middle part of the inner side of the U-shaped plate 12 is fixedly connected with a middle plate 21. Through the setting of the middle plate 21, it is convenient to push the middle part of the sweater out of the lampshade 2, further improving the silkiness during the process of taking out the sweater.

[0024] In order to improve the stability of the device during operation, the outer side of the rectangular groove 18 is set to a smooth arc surface, which is convenient for the rectangular plate 17 to be better squeezed and slid into the rectangular groove 18, thereby improving the smoothness of the device during operation. The push plate 13 is fixedly connected to one side close to the push plate 13. Through the setting of the rubber pad 26, the anti-slip property of the push plate 13 when pushing the sweater on the lampshade 2 is improved, and the sweater can be removed from the lampshade 2 more conveniently.

[0025] In order to make the lampshade 2 rotate flexibly, it is convenient for the inspectors to inspect the sweater at multiple angles, and the rotation position of the lampshade 2 can be reset when the sweater is taken out, the reset mechanism includes a rack 27, a rectangular frame 28 is fixedly connected to the bottom of the sliding plate 3, a pair of racks 27 are provided, and the side walls of the racks 27 are fixedly connected to sliding blocks 29, a pair of sliding grooves 30 are opened inside the rectangular frame 28, and the sliding blocks 29 are slidably connected to the inner sides of the sliding grooves 30, and a disk 31 is fixedly connected to the bottom of the circular frame 5. It should be noted that there is a certain distance between the disk 31 and the horizontal plate 6, which will not hinder the normal turning of the horizontal plate 6, and a gear 32 that meshes with the rack 27 is fixedly connected at the center position of the bottom of the disk 31 and located inside the rectangular frame 28, and the lower electric telescopic cylinder 33 is fixedly connected on both sides of the rectangular frame 28, and the output end of the lower electric telescopic cylinder 33 passes through the inner side of the rectangular frame 28 and is fixedly connected to a pushing plate 34 for pushing the rack 27, and a moving groove is opened at the top of the inspection platform 1 and at a position corresponding to the rectangular frame 28; Since the rack 27 is restricted by the sliding of the sliding block 29 on the inner side of the sliding groove 30, the circular frame 5 and the disc 31 can only rotate to one side, pushing the rack 27 to slide outward, thereby satisfying the rotation of the lampshade 2, ensuring that the inspector can perform multi-angle inspection on the sweater. After the inspection is completed, when the sliding plate 3 is moved to one side of the inspection table 1 by the upper electric telescopic cylinder 10, one of the lower electric telescopic cylinders 33 in the corresponding direction can be controlled to start and drive the push plate 34 to move, thereby pushing the rack 27 and the sliding block 29 to slide on the inner side of the sliding groove 30, and at the same time driving the meshing gear 32 to rotate until the sliding block 29 is pushed to the end of the sliding groove 30. At this time, a group of lampshades 2 on the cross plate 6 are in a state perpendicular to the sliding plate 3, which is convenient for the normal material removal of the subsequent discharging mechanism. After the operation of the discharging mechanism is completed, the lower electric telescopic cylinder 33 is controlled to reset to release the squeezing of the rack 27.

[0026] In order to improve the convenience of the device, a material receiving platform 35 is provided on both sides of the detection platform 1, and the inclined surface of the material receiving platform 35 is inclined. Through the setting of the material receiving platform 35, it is convenient to discharge the wool sweater pushed out by the discharging mechanism. Before the detection, the material box can be placed on the front side of the material receiving platform 35 to ensure that the wool sweater sliding down from the material receiving platform 35 can be collected in the material box. A control panel 36 is fixedly connected to the front side of the detection platform 1, and the control panel 36 is electrically connected to the upper electric telescopic cylinder 10, the reset mechanism, the rotating motor 9 and the discharging mechanism through the controller. Through the setting of the control panel 36, the upper electric telescopic cylinder 10, the lower electric telescopic cylinder 33, the rotating motor 9 and the double-headed electric telescopic cylinder 16 can be electrically connected together, and then by setting the program, the removal of the wool sweater and the replacement of the position of the lampshade 2 can be automatically controlled, thereby improving the automation efficiency of the device.

[0027] In order to adjust the spacing between the discharging mechanisms according to the distance between the lampshades 2 during the sweater inspection, the adjustment mechanism includes a screw 37, two pairs of screws 37 are provided, and vertical plates 38 are fixedly connected to the top of the inspection table 1 and located on the side walls of the right-angle block 15, and the screws 37 are threadedly connected to the side walls of the vertical plates 38, and the side walls of the screws 37 are rotatably connected to the side walls of the right-angle block 15, and a pair of guide rods 39 are fixedly connected to the side away from the right-angle block 15, and the side walls of the guide rods 39 are all set through the side walls of the vertical plates 38, and a scale groove 40 is opened on the top of one of the guide rods 39 on the vertical plates 38; When adjusting the opening detection distance between the lampshades 2 according to wool sweaters of different sizes, it is necessary to rotate the screw 37. Since the screw 37 and the vertical plate 38 are connected by a threaded connection, the screw 37 is spirally moved outward or inward, thereby driving the right-angle block 15 to move, and at the same time driving the guide rod 39 to slide on the vertical plate 38 to play a guiding role, thereby preventing the right-angle block 15 from rotating with the screw 37, thereby improving the stability of the device during operation. At the same time, the distance of movement of the right-angle block 15 can be accurately adjusted by the position of the scale groove 40 on the guide rod 39 on the vertical plate 38, thereby ensuring the normal operation of the discharging mechanism and improving the general performance of the device.

[0028] A method for detecting defects in a wool sweater comprises the following steps: Step 1: Testing: the finished wool sweater is put on one set of lampshades 2 for testing; Step 2: Replacement. After the inspection is completed, the upper electric telescopic cylinder 10 is controlled to start pushing the sliding plate 3 to move, and the position of the lampshade 2 is changed. At the same time, one of the reset mechanisms in the corresponding direction is controlled to start rotating the group of lampshades 2 that have been inspected to a state perpendicular to the sliding plate 3. Then the rotating motor 9 is controlled to drive the horizontal plate 6 to rotate. After the sliding plate 3 slides into place, the other group of lampshades 2 is moved to the middle of the inspection table 1. The inspector can detect the defects of the sweater on the other group of lampshades 2. Step three, unloading, then control the unloading mechanism to start pushing the sweaters on one group of lampshades 2 that have been inspected out of the lampshades 2, and finally after the inspection of the sweaters on another group of lampshades 2 is completed, control the upper electric telescopic cylinder 10 to start and repeat the above operation in reverse.
