[0021] The clamping assembly includes a left clamping unit and a right clamping unit. The left clamping unit includes a left cylinder 7, a left slide rod 8 and a left sleeve 9. The cylinder body of the left cylinder 7 is fixed on the left bracket 2. The tail of the left sleeve 9 is fixed to the protruding end of the left cylinder 7. The left sleeve 9 is slidably connected to the guide rod 4 through the left slide rod 8.

[0022] The right clamping unit includes a right cylinder 10, a right slide rod 11 and a right sleeve 12. The cylinder body of the right cylinder 10 is fixed on the right bracket 2, the tail of the right sleeve 12 is fixed to the protruding end of the right cylinder 10, and the right sleeve 12 is slidably connected to the guide rod 4 through the right slide rod 11.

[0023] The left sleeve 9 and the right sleeve 12 are both cylindrical. The head of the left sleeve 9 has an outer edge ring 9-1 and a central axis 9-2. The outer edge ring 9-1 is located at the outer edge of the head of the left sleeve 9, and the central axis 9-2 is located at the center of the outer edge ring 9-1. The head of the right sleeve 12 has an insert ring 12-1, which is located between the outer edge and the center of the head of the right sleeve 12. The head of the left sleeve 9 and the head of the right sleeve 12 are arranged opposite to and matched with each other.

[0024] Both the left clamping unit and the right clamping unit are provided with a set of ratchet moving components, which include a motor 13, a screw 14 and a ratchet fixing part 15. The motor 13 drives the screw 14 to rotate, and the ratchet fixing part 15 is threadedly connected to the screw 14; the motor 13 of the ratchet moving component of the left clamping unit is fixed under the left sleeve 9, and the ratchet fixing part 15 of the ratchet moving component of the left clamping unit is sleeved on the left sleeve 9, and the motor 13 of the ratchet moving component of the right clamping unit is fixed under the right sleeve 12, and the ratchet fixing part 15 of the ratchet moving component of the right clamping unit is sleeved on the right sleeve 12.

[0025] A group of mounting grooves 16 are provided on the outer wall of the left sleeve 9 and the right sleeve 12. Each group of mounting grooves 16 is circumferentially arranged around the left sleeve 9 or the right sleeve 12 where it is located. Figure 6 In the illustrated embodiment, a set of mounting slots 16 comprises four mounting slots 16 evenly distributed around the circumference. Each mounting slot 16 houses an extension mechanism comprising an air valve 17, a bellows 18, a sealing block 19, and a top block 20. Air passages 21 are provided within both the left and right sleeves 9 and 12. The extension mechanism communicates with the air passages 21 via the air valves 17, which in turn connect to an external inflation mechanism via a pipeline. The air valves 17, bellows 18, and sealing block 19 form a sealed structure. The top block 20 is secured to the sealing block 19, positioned adjacent to the notch of the mounting slots 16, while the air valves 17 are positioned adjacent to the air passages 21.

[0026] like Figure 5 As shown, the ratchet fixing portion 15 includes a collar 15-1 and a ratchet-shaped groove 15-2. The ratchet-shaped groove 15-2 is provided on one side of the collar 15-1. The inner wall of the collar 15-1 has a protrusion 15-3. The outer walls of the left and right sleeves 9, 12 are provided with a sliding groove, and the protrusion 15-3 slides in the sliding groove. The ratchet-shaped grooves 15-2 of the left and right clamping units are arranged opposite each other. The provision of the protrusion 15-3 can fix the ratchet fixing portion 15, preventing the ratchet fixing portion 15 from rotating about the left and right sleeves 9, 12, thereby improving the precision of the coaxial clamping of the belt reel and the ratchet.

[0027] The tops of the left slide bar 8 and the right slide bar 11 are both provided with a slide block 22, which is slidably connected to the guide rod 4. The bottoms of the left slide bar 8 and the right slide bar 11 are fixedly connected to the left sleeve 9 and the right sleeve 12 respectively.

[0028] like Figure 4 As shown, support parts 6-2 are provided on both sides of the supporting part 6-1 of the bracket 6, the supporting part 6-1 connects the two supporting parts 6-2, and the supporting part 6-1 is located in the middle of the supporting parts 6-2, and there is a gap 6-3 between the two supporting parts 6-2.

[0029] The reel includes a tape drum and ratchets coaxially arranged on both sides. A production device for a reel of the present invention is suitable for clamping tape drums of different thicknesses and lengths, and can fix the tape drum and the ratchet coaxially, which is convenient for welding and improves production accuracy. The support assembly is used to support the entire device. The base 1, the bracket 2 and the crossbeam 3 form a frame structure to improve the stability of the support. The pushing assembly is used to push the reel of the reel upward. After it is pushed to the position of the clamping assembly, the clamping assembly clamps and fixes the reel. The two ratchets of the reel are respectively placed on the left and right ratchet moving assemblies. The ratchet moving assembly pushes the two ratchets close to the tape drum and coaxially abuts against it, thereby achieving the clamping and fixation of the reel.

[0030] The specific working process of the production equipment for a retractor of the present invention is as follows:

[0031] In the initial position, the left sleeve 9 of the left clamping unit and the right sleeve 12 of the right clamping unit are spaced apart, placing the reel drum on the top surface of the support portion 6-1 of the bracket 6. Because this top surface is a concave arc, the drum drum can be stably placed. The two support portions 6-2 of the bracket 6 can be connected to the push cylinder 5 to achieve the raising and lowering of the bracket 6. The gap 6-3 between the two support portions 6-2 is to prevent interference with the screws 14 of the two ratchet moving assemblies, and the gap 6-3 avoids the screws 14. The cylinder 5 is pushed to raise the tape reel on the bracket 6 to the same height as the left sleeve 9 and the right sleeve 12. Then, the left cylinder 7 of the left clamping unit and the right cylinder 10 of the right clamping unit are driven simultaneously, so that the head of the left sleeve 9 and the head of the right sleeve 12 approach each other. The head of the left sleeve 9 enters the tape reel from the left side, and the head of the right sleeve 12 enters the tape reel from the right side. The left cylinder 7 and the right cylinder 10 are continued to be pushed. The heads of the left sleeve 9 and the right sleeve 12 are plugged into each other, and the plug ring 12-1 is inserted into the insertion space between the outer edge ring 9-1 and the central axis 9-2 to form a plug-in structure, so that the left sleeve 9 and the right sleeve 12 are connected as a whole. The structure of the left sleeve 9 and the right sleeve 12 can be used to clamp tape reels of different lengths. In order to be able to fix tape reels of different thicknesses on the left sleeve 9 and the right sleeve 12, an extension mechanism is installed in the mounting groove 16 on the outer wall of the left sleeve 9 and the right sleeve 12. The air channel 21 is connected to the external inflation mechanism through a pipeline. When the air channel 21 is inflated, the air valve 17 in the extension mechanism is opened, and the bellows 18 is inflated. After inflation, the bellows extends, pushing the sealing block 19 toward the notch of the mounting groove 16. The top block 20 is located near the notch of the mounting groove 16. After inflation, the top block 20 can be extended to support the inner wall of the tape reel. Multiple extension mechanisms can be used to support multiple parts of the tape reel. The extension distance of the top block 20 can be controlled by controlling the inflation amount of each bellows 18. Since different parts are subjected to different forces, the extension amount of the top block 20 can be measured to determine whether the tape reel is coaxial with the left sleeve 9 and the right sleeve 12. For example, a distance sensor can be installed on the top block 20 or in the notch of the mounting groove 16 to detect the extension amount of the top block 20. After the belt reel is fixed, the two ratchets are placed in the ratchet-shaped grooves 15-2 of the ratchet fixing parts 15 of the two sets of ratchet moving assemblies, the driving motor 13 rotates to rotate the screw 14, and the ratchet fixing parts 15 of the two sets of ratchet moving assemblies are moved close to each other, and the ratchet fixing parts 15 are sleeved on the left sleeve 9 or the right sleeve 12 where they are located, and the ratchet-shaped grooves 15-2 are coaxial with the left sleeve 9 and the right sleeve 12, so that the two ratchets are coaxial with the belt reel on the left sleeve 9 and the right sleeve 12, thereby realizing the coaxial fixation of the two ratchets and the belt reel, facilitating welding and improving welding accuracy.
