Description
Technical Field
[0001] This utility model relates to the field of shrink tubing technology, and in particular to an automatic heat shrink tubing shrink machine. Background Technology
[0002] Automatic heat shrink tubing shrinking machines are mainly used for automatically shrinking long heat shrink tubing to ensure the insulation and stability of the connection. They play a key role in many fields such as electrical equipment manufacturing, automobiles, machinery, and construction, and are also widely used in aerospace, pharmaceuticals, and home decoration industries. Moreover, the applications of heat shrink tubing have spread to various products. The heat shrink tubing passes through the wire harness connector, and then is heated to shrink the heat shrink tubing, tightly wrapping the wire harness connector, making the wire harness connection more stable.
[0003] Current heat shrink machines still have the following shortcomings during installation and use by users:
[0004] (1) Traditional heat shrink tubing shrinks by having multiple people hold a hot air gun and blow hot air back and forth on each heat shrink tubing to shrink it, which increases the labor force of employees, increases labor costs, reduces work efficiency, and manual operation cannot guarantee the consistency of heat shrink quality.
[0005] (2) When multiple heat shrink tubes are shrunk at the same time, if the heat shrink tubes are placed too close together, they will stick together, which will lead to heat shrink failure and waste of materials. If the distance is too far, the number of heat shrinks each time will be reduced, thus reducing work efficiency. Utility Model Content

[0035] like Figures 1 to 6 As shown in the figure, this embodiment provides an automatic heat shrink tubing shrinking machine, including a base 1, a placement net 2 on the top of the base 1, a heating shrinking assembly 3 on the base 1, and straightening assemblies 4 at both ends of the base 1.
[0036] The heat shrink assembly 3 includes a movable base 31, a first heater 32 on the movable base 31, a top seat 33 on the top of the movable base 31, and a second heater 34 at the bottom of the top seat 33. The placement net 2 is located between the first heater 32 and the second heater 34. The movable base 31 is threadedly connected to a first lead screw 35, and the first lead screw 35 is rotatably connected to the base 1. The two first lead screws 35 have the same thread direction. One end of the first lead screw 35 is provided with a transmission mechanism. The base 1 is provided with a first drive mechanism. A rotation mechanism is provided between the movable base 31 and the top seat 33. The first drive mechanism drives the first lead screw 35 to rotate.

The other end of the movable seat 31 has a slot 382, and the other end of the top seat 33 is locked inside the slot 382. The other end of the top seat 33 has a handle 383. The top seat 33 is disengaged from the slot 382 by the handle 383. Then, the top seat 33 rotates along the movable seat 31 via the rotating shaft 381, which facilitates subsequent material loading operations.
[0040] The base 1 has a first mounting cavity 101 inside, the motor 372 is located inside the first mounting cavity 101, the first mounting cavity 101 has a second mounting cavity 102 on each side, the first sprocket 361 and the second sprocket 363 are located inside the second mounting cavity 102, and the first mounting cavity 101 has a third mounting cavity 103 above it, which facilitates the installation and fixing of the dual-head motor 481.
[0041] The straightening assembly 4 includes a first clamping block 41 with several first V-grooves 42. A second clamping block 43 is located above the first clamping block 41 with several second V-grooves 44. A clamping mechanism is located at the top of the second clamping block 43. Two sets of guide rods 46 are located at both ends of the base 1. The guide rods 46 are slidably connected to the first clamping block 41. A circular plate 47 is located at one end of the guide rod 46. A second driving mechanism is located at the bottom of the first clamping block 41. The second driving mechanism drives the two sets of first clamping blocks 41 and second clamping blocks 43 to move in opposite directions, thereby straightening the connector wire harness and preventing the heat shrink tubing from sticking together due to the close spacing.
[0042] The clamping mechanism includes a movable plate 451, a sliding rod 452 symmetrically provided on the top of the first clamping block 41, the sliding rod 452 being slidably connected to the second clamping block 43, the movable plate 451 being fixedly connected to the sliding rod 452, a threaded rod 453 being threadedly connected to the movable plate 451, a turntable 454 being provided at the top of the threaded rod 453, a limiting plate 455 being provided at the bottom of the threaded rod 453, a connecting seat 456 being provided at the top of the second clamping block 43, the limiting plate 455 being located inside the connecting seat 456, the connecting seat 456 being rotatably connected to the threaded rod 453, the turntable 454 driving the threaded rod 453 to rotate, the threaded rod 453 moving downward along the movable plate 451, the threaded rod 453 pushing the second clamping block 43 downward through the limiting plate 455, and the wire harness being clamped by the first clamping block 41 and the second clamping block 43.
[0043] The second drive mechanism includes a dual-head motor 481, which is installed inside the third mounting cavity 103. The two output ends of the dual-head motor 481 are respectively connected to the second lead screw 482. The second lead screw 482 is rotatably connected to the base 1. The base 1 has L-shaped plates 483 at both ends, and the threads on the two L-shaped plates 483 are in opposite directions. The L-shaped plates 483 are rotatably connected to the second lead screw 482. The second lead screw 482 is threadedly connected to a slide table 484, which is fixedly connected to the first clamping block 41. The dual-head motor 481 drives the two second lead screws 482 to rotate, and the two second lead screws 482 drive the two slide tables 484 to move in opposite directions. The two slide tables 484 drive the two first clamping blocks 41 to move in opposite directions, thereby straightening the connector harness.
[0044] In use, the operator pulls the handle 383 upwards, causing the top seat 33 to disengage from the slot 382. The top seat 33 then rotates along the movable seat 31 via the rotating shaft 381, facilitating subsequent loading operations. Afterwards, the top seat 33 is returned to its initial position. Next, the multiple connectors of the heat shrink tubing are placed on the placement net 2, with both ends of the connectors inserted into the first V-groove 42 on the first clamping block 41. The operator then rotates the turntable 454, which drives the threaded rod... Rotation 453 causes the threaded rod 453 to move downwards along the movable plate 451. The threaded rod 453, via the limiting plate 455, pushes the second clamping block 43 downwards along the slide rod 452. The first clamping block 41 and the second clamping block 43 clamp both ends of the wire harness. Then, the dual-head motor 481 is activated, driving the two second lead screws 482 to rotate. The two second lead screws 482 respectively drive the two slide tables 484 to move in opposite directions. The two slide tables 484 respectively drive the two first clamping blocks 41. Moving along the guide rod 46 in the opposite direction straightens the connector harness, preventing the heat shrink tubing from sticking together due to excessively close spacing. This also ensures the quantity of heat shrink tubing shrunk each time, thus maintaining work efficiency. Finally, the motor 372 is started, driving the double-groove pulley 374 on the second shaft 373 to rotate. The double-groove pulley 374 drives the single-groove pulley 375 to rotate via pulley 376. The single-groove pulley 375 drives the first shaft 362 to rotate, which in turn drives the second sprocket 363 to rotate. The second sprocket 363 drives the first lead screw 35 on the first sprocket 361 to rotate via chain 364. The first lead screw 35 drives the first heater 32 on the moving seat 31 and the second heater 34 on the top seat 33 to move along the placement net 2, thereby heating and shrinking the heat shrink tubing placed on the placement net 2. This eliminates the need for manual shrinking, reducing labor costs, improving work efficiency, and ensuring consistent heat shrinking quality.
