Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing expander technology, and more specifically, to a heat shrink tubing expander equipped with a cooling device. Background Technology

[0002] A heat shrink tubing expander first heats the heat shrink tubing, then expands it using the expander. Once expanded to the required size, a cooling device cools and shapes the heated portion.

[0003] According to Chinese Patent CN202123151587.0, a heat shrink tubing expander with a cooling device is used. This application sets up a feeding mechanism, which uses a motor to drive upper and lower gears, thereby rotating upper and lower rollers inside the housing. A slot is formed on the upper roller, through which the heat shrink tubing moves forward. A concave block limits the movement of the heat shrink tubing, ensuring it always moves vertically forward. This prevents uneven progress of the four heat shrink tubing tubes during heating and expansion, thus affecting product quality and accelerating production speed. Existing heat shrink tubing expanders have an unadjustable gap between the upper and lower rollers in the feeding mechanism, making it difficult to effectively compress the heat shrink tubing. This leads to slippage during transport, affecting the efficiency of heat shrink tubing transport.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

A plurality of evenly distributed feed holes 8 are opened on the inner wall of the U-shaped conveyor frame 2 and are connected to the feed end of the expander body 1.

[0026] Example 2;

[0027] like Figure 1-5As shown, the device includes an expander body 1. A U-shaped conveyor frame 2 is located on one side of the expander body 1 at the feed end. Several evenly distributed material guide pipes 3 are located on the side of the U-shaped conveyor frame 2 away from the expander body 1. The U-shaped conveyor frame 2 contains symmetrically arranged U-shaped mounting seats 1 and 2, 5. Symmetrically arranged conveying rollers 6 are positioned between the U-shaped mounting seats 1 and 2, 4 and 5 respectively. The two sets of conveying rollers 6 are connected to the U-shaped mounting seat 1 via a spacing adjustment assembly and to the U-shaped mounting seat 2 via a linkage rotation assembly. Conveying grooves 7 are formed on the outer walls of both sets of conveying rollers 6. The inner wall of the U-shaped conveyor frame 2 has several evenly distributed feed holes 8 that communicate with the feed end of the expander body 1. The spacing adjustment assembly includes a lead screw 9 located in the U-shaped mounting seat 1. Symmetrically arranged moving blocks 10 are sleeved on the outer wall of the lead screw 9. The shaft ends of the two sets of conveying rollers 6 are rotatably connected to the two sets of moving blocks 10 respectively. The lead screw 9 is connected to the U-shaped mounting base 4 via a bearing. The top end of the lead screw 9 extends outside the U-shaped mounting base 4 and is connected to the drive end of the servo motor 11. Both sets of moving blocks 10 have threaded holes 12 that match the lead screw 9. The thread directions of the two sets of threaded holes 12 are opposite. Each set of moving blocks 10 has a guide block 13 on the side away from the conveying roller 6. The inner wall of the U-shaped mounting base 4 has a guide groove 14 that matches the guide block 13. The linkage rotation assembly includes a rotating shaft 15 provided in the U-shaped mounting base 2 5. The outer wall of the rotating shaft 15 is fitted with symmetrically arranged sleeves 16. Both sets of sleeves 16 are connected to two sets of conveying rollers 6 respectively through L-shaped connecting frames 17. Both sets of sleeves 16 are fitted with symmetrically arranged helical gears 18 at their near ends and on the outer wall of the rotating shaft 15. The helical gears 18 are fixedly connected to the sleeves 16. The sleeves 16 are rotatably connected to the L-shaped connecting frames 17.

[0028] In practical applications, four sets of heat shrink tubing are inserted into the feeding guide tube 3, pushing the heat shrink tubing to the feeding groove 7 on the two sets of feeding rollers 6. Then, the servo motor 11 is started to drive the lead screw 9 to rotate. The lead screw 9 drives the two sets of moving blocks 10 to move close together. The two sets of moving blocks 10 drive the two sets of feeding rollers 6 to move close together to squeeze the heat shrink tubing, so that the feeding rollers 6 and the surface of the heat shrink tubing are in full contact. Then, the drive motor 20 is started to drive the rotating shaft 15 to rotate. The rotating shaft 15 drives the two sets of helical gears 18 to rotate through the limit key 21. The helical gears 18 drive the two sets of feeding rollers 6 to rotate in opposite directions through the helical gears 19. The two sets of feeding rollers 6 drive the four sets of heat shrink tubing to move synchronously until the heat shrink tubing enters the body 1 of the expander through the corresponding feed hole 8 for expansion processing. By setting the spacing adjustment component and the linkage rotation component, the spacing between the two sets of feeding rollers can be adjusted to squeeze the heat shrink tubing, which facilitates the conveying of the heat shrink tubing and prevents slippage between the feeding rollers and the heat shrink tubing, thus affecting the conveying efficiency.

[0029] In summary, by means of the above-mentioned technical solution of this utility model, the distance between the two sets of conveying rollers can be adjusted by setting the spacing adjustment component and the linkage rotation component, so as to squeeze the heat shrink tubing, which facilitates the conveying of the heat shrink tubing and prevents slippage between the conveying rollers and the heat shrink tubing, thus affecting the conveying efficiency.
