[0027] In this embodiment, a groove wheel 30 is rotatably installed on the top of the heat shrink machine body 1, and the fixed metal block 28 is adapted to the multiple grooves on the outside of the groove wheel 30.

The wire reel can be divided by multiple dividing rods 32.

[0028] Working principle: When in use, the staff places the rolled wire reel on the first conveyor belt 4, starts the machine through the control panel 2, the first conveyor belt 4 starts to transport the wire reel, and the first wire reel reaches the limit rod 24. Since the first conveyor belt 4 drives the wire reel to move, the wire reel pushes the limit rod 24 to move. The movement of the limit rod 24 drives the limit column 25 to move. The movement of the limit column 25 drives the limit slider 26 to move. Since one end of the limit rod 24 is sleeved on the rotating column 23, the movement range of the limit rod 24 is limited, and the movement of the limit slider 26 stretches the limit spring 27 At this time, the limit spring 27 is stretched by the force and drives the fixed metal block 28 to move. The fixed metal block 28 moves and leaves the groove of the groove wheel 30. At this time, the first conveyor belt 4 starts to transport the second wire reel, and the second wire reel drives the dividing rod 32 to move. At this time, the rotation of the groove wheel 30 is not restricted, so the movement of the dividing rod 32 drives the dividing plate 31 to rotate, so that the second wire reel passes through the dividing mechanism. At the same time, the first wire reel drives the limit rod 24 to rotate to the maximum angle, and the wire reel cannot be blocked. The first wire reel moves to the second conveyor belt 5. At this time When the thrust of the first wire reel is lost, the reset spring 29 drives the fixed metal block 28 to rebound, and the fixed metal block 28 limits the groove wheel 30. As the fixed metal block 28 is reset, the limit spring 27 connected to the limit rod 24 is rebounded, and the limit rod 24 is reset, and this process is repeated. At this time, the staff installs the packaging film roll 21 at the specified position, stretches the packaging film roll 21, and makes the fixed clamp 16 and the movable clamp 10 clamp the front end of the packaging film roll 21 at the same time. At this time, the mobile servo motor 7 starts to drive the ball screw 8 to rotate, and the rotation of the ball screw 8 drives the movable slider 9 to move, and the movable slider 9 moves. The movable slider 9 moves and drives the movable clamp 10 to move. When one end of the packaging film roll 21 is driven by the movable clamp 10 to be stretched to the specified position, the two cutting servo motors 12 are started and drive the corresponding cutting gears 13 to rotate. The two cutting gears 13 rotate and drive the corresponding cutting spur racks 14 to move downward. The two cutting spur racks 14 move downward and drive the corresponding cutting knives 15 to move downward. The two cutting knives 15 move downward to cut the packaging film. The cut packaging film is covered on the wire reel by gravity, and then follows the wire reel into the heat shrink assembly 3 for heat shrinkage to complete the packaging.

[0029] The technical progress achieved by the utility model compared with the prior art is that: through the set mechanism, the work of automatically coating the wire reel is realized, which improves the work efficiency and saves labor costs, and can automatically divide the wire reels on the conveyor belt, thereby effectively preventing the safety hazards caused by multiple wire reels entering the heat shrink machine at the same time, and can also improve the quality of the product.
