The first cylinder 16 drives the mounting frame 13 through the swing arm 15. The mounting frame 13 is used to mount the take-up drum assembly 2, which is used to take up foam. The second bracket 17 is used to mount the motor 18, which is used to drive the drive wheel 19. The take-up drum assembly 2 includes a take-up drum body 21, an air intake 22, a hollow shaft 23, a mounting groove 24, a spring 25, a limiting block 26, a baffle 27, a limiting groove 28, a first slider 29, a positioning groove 210, a driven wheel 211, an air pipe connector 212, a plug 213, and a pressure...

The take-up drum body 21 is used to take up foam, the hollow shaft 23 is used to drive the take-up drum body 21, and the baffle 27 is used to limit the movement of the foam. The positioning groove 210, in conjunction with the positioning block 14, achieves positioning between the baffle 27 and the mounting frame 13. A driven wheel 211 is provided on one side of the baffle 27. Furthermore, the driven wheel 211 is fixedly connected to the hollow shaft 23. The driven wheel 211 is located at the bottom end of the drive wheel 19. The drive wheel 19 drives the hollow shaft 23 to rotate by driving the driven wheel 211.

The input end of the air pipe connector 212 is connected to a vacuum pump 3. The vacuum pump 3 evacuates air from the hollow shaft 23 through the air pipe connector 212. Since the other hollow shaft 23 is closed by the plug 213, suction force is generated at the suction hole 22, thereby fixing the beginning end of the foam.A mounting groove 24 is provided on the hollow shaft 23. A spring piece 25 is fixedly connected in the mounting groove 24. A limit block 26 is fixedly connected to the spring piece 25. A limit groove 28 is provided on the baffle 27 at the position corresponding to the limit block 26.

The mounting groove 24 is used to accommodate the spring piece 25 and the limit block 26. The spring piece 25 is used to provide a reset spring force for the limit block 26. The limit groove 28, in conjunction with the limit block 26, can fix the relative position of the hollow shaft 23 and the baffle 27, so that the hollow shaft 23 cannot rotate. The second bracket 17 can trigger the first slider 29 to move down. The first slider 29 is used to push the limit block 26 out of the limit groove 28, so that the hollow shaft 23 can rotate. One of the second brackets 17 is fixed with A second cylinder 110 is connected, and the output end of the second cylinder 110 is fixedly connected to the air pipe connector 212. The second cylinder 110 is used to drive the air pipe connector 212. A pressure rod 214 is provided at the top of the take-up drum body 21.

A spring 218 is sleeved on the guide rod 216, and one end of the spring 218 is set on the second slider 215, and the other end is set in the through groove 217. The guide rod 216 is used to install the second slider 215 and the spring 218. The through groove 217 is used to accommodate the second slider 215 and the guide rod 216. The spring 218 is used to apply pressure to the second slider 215. The pressure rod 214 is used to lock the end of the foam.

[0022] Working principle: When using this utility model, the take-up drum assembly 2 is placed in the mounting bracket 13, so that the positioning block 14 is inserted into the positioning groove 210. The first cylinder 16 retracts, and the mounting bracket 13 is deflected on the first bracket 12 via the swing arm 15, so that the driven wheel 211 is in contact with the drive wheel 19. At this time, the first slider 29 is pushed down by the second bracket 17. The first slider 29 slides down along the limiting groove 28, pushing out the limiting block 26 in the limiting groove 28. The limiting block 26 is pressed into the mounting groove 24, and the spring piece 25 is deformed, conveying the foam head end to the take-up drum body 21 and the pressure rod 2. Between points 14, the second cylinder 110 extends, allowing the air pipe connector 212 to be fitted onto one of the hollow shafts 23. The vacuum pump 3 is activated, drawing air from the take-up drum body 21 via the air pipe connector 212 and the hollow shaft 23, creating suction at the suction port 22. This suction then adheres and fixes the foam head end to the take-up drum body 21. The motor 18 is then activated, driving the drive wheel 19, which in turn drives the driven wheel 211. The hollow shaft 23 on the driven wheel 211 rotates accordingly, causing the take-up drum body 21 to rotate and wind up the foam. Simultaneously, the spring 218 engages the second slider. The elastic force applied by 215 causes the pressure rod 214 on the second slider 215 to press the foam on the take-up drum body 21. After the take-up drum body 21 rotates a set number of times, the vacuum pump 3 is turned off, the second cylinder 110 retracts, and the air pipe connector 212 is reset. After the take-up drum body 21 rotates a set number of times, the foam is cut by the cutting device, completing the winding operation. At this time, the first cylinder 16 extends, causing the mounting bracket 13 to deflect and reset. The first slider 29 moves away from the second bracket 17, and under the elastic action of the spring piece 25, the limiting block 26 resets and inserts into the limiting groove 28, causing the stop... The positions of plate 27 and take-up drum body 21 are relatively fixed to prevent the take-up drum body 21 from rotating relative to pressure rod 214, thereby avoiding the foam roll from loosening. When the mounting bracket 13 is reset to the initial position, the take-up drum assembly 2 can be directly replaced. The base plate 11 is used to install the first bracket 12 and the second bracket 17. The plug 213 is used to close one of the hollow shafts 23. The guide rod 216 is used to install the second slider 215 and the spring 218. The through groove 217 is used to accommodate the second slider 215 and the guide rod 216. The cutting device adopts existing technology and will not be described in detail here.
