The waste collection box 6 is located below the cloth spreading board 5, and a handle 7 is welded on the front side of the waste collection box 6 to facilitate pulling it out of the base 1. Figure 4 As shown, a collecting hole is drilled on the top of the waste collecting box 6, and a vacuum pump 8 is bolted to the waste collecting box 6. The air suction hole of the vacuum pump 8 is sealed and connected to the waste collecting box 6, and the air outlet of the vacuum pump 8 is located on the outside of the waste collecting box 6, so as to generate negative pressure in the waste collecting box 6.

[0026] The cloth spreading board 5 is drilled with a perforation, which vertically penetrates the cloth spreading board 5 downward and corresponds to the collection hole on the waste collection box 6. A pipe assembly is assembled between the cloth spreading board 5 and the waste collection box 6, and the pipe collection assembly is connected to the perforation on the cloth spreading board 5 and the collection hole on the waste collection box 6 in a butt-jointed manner, so as to collect the waste cloth cut by punching.

[0027] like Figure 2 As shown, the pipeline collection assembly includes a fixed pipe 9 and a sleeve 10. The fixed pipe 9 penetrates into the perforation of the cloth-laying board 5 and is fixedly connected to the cloth-laying board 5. The fixed pipe 9 matches the perforation and is correspondingly sealed and connected. The sleeve 10 is slidably sleeved on the fixed pipe 9. The top bolts of the sleeve 10 fix multiple vertical first telescopic rods 12, and the multiple vertical first telescopic rods 12 are evenly distributed along the circumference of the fixed pipe 9, and the output ends of the multiple vertical first telescopic rods 12 are all vertically upward and fixedly connected to the cloth-laying board 5. A first spring 13 is sleeved on each first telescopic rod 12, and the top end of each first spring 13 is fixedly connected to the cloth-laying board 5, and the bottom end of each first spring 13 is fixedly connected to the sleeve 10 for resetting the sleeve 10. The sleeve 10 is connected to the collection hole on the waste collection box 6 in a butt-jointed sealed manner.

[0028] like Figure 4 As shown, two isosceles trapezoidal protrusions 11 are welded on the top of the waste collection box 6, and the two protrusions 11 are symmetrically arranged on the front and rear sides of the collection hole. The sleeve 10 is slidably abutted against the two protrusions 11 to drive the sleeve 10 to slide up and down along the fixed tube 9, thereby facilitating the sliding of the waste collection box 6.

[0029] like Figure 2 As shown, the bottom of the punching cutter head 3 is fixedly equipped with a punching blade 4, which is annular and matches the perforations on the cloth spreading board 5. The punching blade 4 can be slidably inserted into the fixed tube 9 in the perforation and is sealed and slidably matched with the fixed tube 9.

[0030] like Figure 1 As shown, the left and right sides of the base 1 are both slidably equipped with a horizontal transmission plate 16, and the two transmission plates 16 are horizontally opposed and can slide up and down and left and right on the base. Mounting holes are cut out at the same positions on the left and right sides of the base 1, and the two mounting holes correspond to the two transmission plates 16 one by one, and each transmission plate 16 is slidably assembled in the corresponding mounting hole. A connecting block is welded to the bottom of the end near each transmission plate 16, and a horizontally placed flattening fixing plate 17 is welded to the bottom of each connecting block. The two flattening fixing plates 17 are parallel to each other and are arranged horizontally front and back. The two flattening fixing plates 17 are in contact and sliding contact with the cloth, and are used to clamp and fix the cloth while flattening the cloth.

[0031] like Figure 2As shown, a pressing assembly is mounted on the punching cutter head 3 , and the pressing assembly cooperates with two transmission plates 16 in transmission, so as to drive the two transmission plates 16 to slide downwards close to the cloth on the spreading plate 5 .

[0032] The pressing assembly includes two horizontally placed pressure rods 15, which are opposite to each other in the horizontal direction and one pressure rod 15 is welded to the left and right sides of the punching cutter head 3. Guide grooves running vertically up and down are cut on the left and right sides of the base 1, and the bottom of each guide groove is connected to the mounting hole on the base body on the same side of the base 1. The two pressure rods 15 correspond to the two guide grooves one by one, and the end of each pressure rod 15 away from the punching cutter head 3 is inserted into the corresponding guide groove and slidably cooperates with the corresponding guide groove. The end of each pressure rod 15 away from the punching cutter head 3 is bolted with a vertical second telescopic rod 25, and each second telescopic rod 25 is located in the guide groove. The output end of each second telescopic rod 25 is vertically downward and welded with a support block 27, and each support block 27 is slidably cooperated with the guide groove where it is located. The bottom of each support block 27 is rotatably connected to a rolling ball 28. The two support blocks 27 correspond to the two transmission plates 16 one by one, and each support block 27 is in transmission cooperation with the corresponding transmission plate 16 to push the two transmission plates 16 to slide downward synchronously to approach the cloth.

[0033] A fourth spring 26 is sleeved on each second telescopic rod 25 , the top end of the fourth spring 26 is fixedly connected to the pressure rod 15 connected to the second telescopic rod 25 , and the bottom end is fixedly connected to the support block 27 connected to the second telescopic rod 25 for pushing buffer and pressure.

[0034] The top of each transmission plate 16 is cut with an arc groove 29 along its own sliding direction, and the rolling ball 28 on each support block 27 corresponds to and matches the arc groove 29 on the transmission plate 16 corresponding to the support block 27. When the support block 27 contacts the corresponding transmission plate 16, the rolling ball 28 on the support block 27 is located in the arc groove 29 on the transmission plate 16 corresponding to the support block 27 and rolls against the corresponding transmission plate 16, which facilitates the transmission plate 16 to slide left and right.

[0035] like Figure 3 and Figure 5As shown, a first reset mechanism is installed between the two transmission plates 16 and the base 1, and the first reset mechanism is used to drive the two transmission plates 16 to slide upward away from the cloth. The first reset mechanism includes a horizontal first limit plate 18 and a vertical second spring 19. Two limit through holes are cut on the left and right sides of the base 1, and the limit through holes horizontally penetrate the base 1 in the horizontal direction. The two limit through holes on the same side of the base 1 are symmetrically distributed on the front and rear sides of the mounting hole on the base and are connected to the mounting hole on the base. The two limit through holes on the same side of the base 1 are limited and slidably matched with the first limit plate 18. The front and rear ends of each transmission plate 16 are cut with a first limit groove, and the first limit plate 18 corresponds to the first limit groove and is inserted into the first limit groove to limit and slide with the first limit groove along the direction in which the transmission plate 16 slides close to or away from the cloth, and at the same time ensure that the first limit plate 18 slides left and right synchronously with the transmission plate 16. Two second springs 19 are arranged in each first limiting groove, one in front and one behind and symmetrically distributed. The top ends of the two second springs 19 are fixedly connected to the transmission plate 16 where the first limiting groove is located, and the bottom ends of the two second springs 19 are fixedly connected to the first limiting plate 18 that is limited and slidably matched with the first limiting groove for resetting.

[0036] The left and right ends of each first limiting plate 18 are welded with a T-shaped limiting slider, and each transmission plate 16 is dug out with a T-shaped first limiting slot that matches the limiting slider. Each first limiting slot is connected to the first limiting groove where the first limiting plate 18 is located. The limiting sliders on the first limiting plate 18 are all located in the corresponding first limiting slots and are limitedly slidably matched with the corresponding first limiting slots, ensuring that the transmission plate 16 does not deflect when approaching or moving away from the cloth.

[0037] The left and right end portions of each first limiting plate 18 are welded with a first limiting block 20 , and each first limiting block 20 is in contact-limited cooperation with the base 1 to ensure that the first limiting plate 18 does not slide off the base 1 .

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the punching cutter head 3 is equipped with a transmission assembly, which cooperates with the two transmission plates 16 to drive the two transmission plates 16 to slide away in the left and right horizontal directions.

[0039] The transmission assembly includes two push rods 14, which are opposite to each other in the horizontal direction and one push rod 14 is welded to the left and right sides of the punching cutter head 3. The two push rods 14 correspond to the two pressure rods 15 one by one, and each push rod 14 is located below the corresponding pressure rod 15, ensuring that the two push rods 14 can contact with the two transmission plates 16. The ends of the two transmission plates 16 are cut with transmission slopes, each of which is located at the top of the transmission plate 16 and is inclined in the direction away from the other transmission plate 16. The two push rods 14 correspond to the two transmission slopes one by one, and the end of each push rod 14 away from the punching cutter head 3 is in contact and sliding contact with the corresponding transmission slope, which is used to push the two transmission plates 16 to slide away. In the process of the two transmission plates 16 sliding away, the end of each push rod 14 away from the punching cutter head 3 is always in contact with the transmission slope of the corresponding transmission plate 16.

[0040] like Figure 2 , Figure 3 and Figure 6 As shown, a second reset mechanism is installed between the two transmission plates 16 and the base 1, and the second reset mechanism is used to drive the two transmission plates 16 to slide closer to each other along the left and right horizontal directions.

[0041] The second reset mechanism includes a third spring 24. A T-shaped second limiting groove is chiseled out at the bottom of each transmission plate 16, and each second limiting groove is opened in the horizontal direction of the left and right and the groove is downward. A T-shaped second limiting groove is cut on the left and right side seats of the base 1, and each second limiting groove is opened in the vertical direction of the upper and lower parts and the top end is connected to the mounting hole on the seat body on the same side of the base 1. A T-shaped second limiting block 21 is provided in each second limiting groove, and a matching limiting sliding fit is provided. Two notches are symmetrically cut out at the top of each second limiting block 21 in the horizontal direction of the left and right parts to form a T-shaped limiting block that matches the second limiting groove. The limiting block is inserted into the second limiting groove and is limitedly slidably matched with the second limiting sliding groove to ensure that the transmission plate 16 can slide up and down and slide left and right.

[0042] The bottom ends of the two transmission plates 16 that are away from each other are welded with a vertical second limit plate 22. A horizontal support rod 23 is welded on each second limit block 21, and the end of each support rod 23 away from the second limit block 21 passes through the second limit plate 22 on the transmission plate 16 connected to the second limit block 21 and slidably cooperates with the second limit plate 22. A third spring 24 is sleeved on each support rod 23, one end of the third spring 24 is fixedly connected to the second limit block 21, and the other end is fixedly connected to the second limit plate 22 for resetting.

[0043] The end of each support rod 23 away from the connected second limit block 21 is coaxially fixedly connected to the abutment plate, and the abutment plate is in contact with the second limit plate 22 that slides with the support rod 23 to ensure that the second limit plate 22 does not slide away from the support rod 23.

[0044] Working principle: Before punching, the cloth is laid on the cloth laying board 5, and the two flattening fixing plates 17 are located above the cloth and have a certain distance from the cloth. The output end of the first telescopic rod 12 and the output end of the second telescopic rod 25 are both in an extended state. The first spring 13 and the second spring 19 are both in a preliminary compression state, the third spring 24 is in a natural extension state, and the fourth spring 26 is in a preliminary extension state.

[0045] During the punching operation, the hydraulic cylinder 2 is started, the output end of the hydraulic cylinder 2 extends downward and drives the punching cutter head 3 to move vertically downward close to the cloth. The punching cutter head 3 simultaneously drives the punching blade 4, two push rods 14 and two pressure rods 15 to move close to the cloth.

[0046] During this process, the two pressure rods 15 drive the connected second telescopic rod 25 and the fourth spring 26 to move closer to the transmission plate 16 below, the second telescopic rod 25 and the fourth spring 26 push the connected support block 27 to move closer to the transmission plate 16, and the support block 27 drives the rolling ball 28 to move closer to the transmission plate 16.

[0047] Afterwards, the ball 28 first falls into the arc groove 29 of the transmission plate 16 and simultaneously forms contact with the transmission plate 16 with the support block 27. Then, as the punching cutter head 3 continues to move downward, the fourth spring 26 changes from initial extension to compression. Thereafter, the transmission plate 16 is pushed downward by the support block 27 under the action of pressure and the elastic force of the fourth spring 26, and the transmission plate 16 drives the paving fixed plate 17 to move closer to the cloth until the paving fixed plate 17 contacts the cloth. In this process, the first limit plate 18 slides relative to the transmission plate 16, and the transmission plate 16 not only deeply compresses the second spring 19, but also drives the second limit block 21 to slide downward along the second limit groove, and at the same time drives the second limit plate 22 to move downward, and the second limit block 21 and the second limit plate 22 drive the support rod 23 to move downward, and the support rod 23 drives the third spring 24 to move downward.

[0048] At this time, the two push rods 14 are in contact with the transmission slope of the transmission plate 16. Then, as the punching cutter head 3 continues to move downward, the two push rods 14 push the two transmission plates 16 to slide away, and the two transmission plates 16 not only drive the flattening fixed plate 17 to slide and abut against the cloth to flatten the cloth, but also drive the flattening fixed plate 17 to fix and clamp the cloth. In this process, the second limit block 21 slides relative to the transmission plate 16, the first limit plate 18 slides synchronously with the transmission plate 16, the third spring 24 is stretched, and the rolling ball 28 rolls and abuts against the transmission plate 16.

[0049] When the bottom of the punching cutter head 3 contacts the cloth, the punching blade 4 has cut off the cloth to complete the punching and is inserted into the fixed tube 9, and the two push rods 14 are still in contact with the transmission inclined surface of the transmission plate 16.

[0050] Afterwards, the hydraulic cylinder 2 is shut down, and the vacuum pump 8 is started at the same time, so that the vacuum pump 8 sucks the cut waste fabric into the waste collection box 6 .

[0051] After the punching is completed, the hydraulic cylinder 2 is started again, and the output end of the hydraulic cylinder 2 is retracted and reset. Finally, under the action of the elastic force of the second spring 19, the two transmission plates 16 slide up and reset; under the action of the pulling force of the third spring 24, the two transmission plates 16 slide close to reset.

[0052] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
