Description

Technical Field:

[0001] The utility model relates to the technical field of heat shrinkage machines, and particularly refers to an automatic heat shrinkage heat shrinkable tube machine. Background Art:

[0002] A heat shrinkage machine is a device that uses hot air or heat radiation to tightly wrap heat shrinkable materials (such as heat shrinkable films, heat shrinkable tubes) on the outer surface of products or packages. The heat shrinkage machine makes the heat shrinkable materials rapidly shrink by heating, so as to fit the product surface, thereby achieving the purposes of sealing, dust prevention, moisture prevention, enhancing aesthetics and protecting articles. The heat shrinkable tube heat shrinkage machine is one type of heat shrinkage machines, which is commonly used in industrial production and is a device specifically for heating and shrinking heat shrinkable tubes. A heat shrinkable tube is a special material used to insulate and protect wires, cables and other electronic components. When it is heated, it will tightly shrink and wrap on the surface of the target object, thereby providing functions such as insulation, moisture prevention, corrosion prevention and mechanical protection.

[0003] The invention patent application with the publication number of CN 115489099 A in China discloses a heat shrinkable tube shrinkage machine. The patent solution includes an XY axis assembly, a Z axis motion module 2, a hot air gun 1 for blowing hot air on the heat shrinkable tube, and a product self-rotation module 4 for driving the heat shrinkable tube 3 to rotate. The heat shrinkable tube 3 is placed on the product self-rotation module 4, and the product self-rotation module 4 is installed on the XY axis assembly. The XY axis assembly is used to drive the product self-rotation module 2 to move along the X axis and Y axis, and the hot air gun 1 is installed on the Z axis motion module. The XY axis assembly includes an X axis motion module 5 and a Y axis motion module 6. The X axis motion module 5, the Y axis motion module 6, and the Z axis motion module 2 all include a lead screw module and a motor 7. The lead screw module includes a lead screw 8 connected to the motor, and a slider installed on the lead screw and reciprocating along the axial direction of the lead screw under the drive of the lead screw. The product self-rotation module 4 is installed on the slider of the X axis motion module 5. The X axis motion module 5 is installed on the slider of the Y axis motion module 6. The hot air gun 1 is installed on the slider of the Z axis motion module 2. The lead screw is connected to the motor output shaft through a coupling, and there is a threaded transmission relationship between the lead screw and the slider. The motor drives the lead screw to rotate, and the slider reciprocates on the lead screw. The motors of the X axis motion module 5, the Y axis motion module 6, and the Z axis motion module 2 are all electrically connected to the PLC. During operation, first, a heat shrinkable tube of a certain specification is sleeved on the wire, and then the wire is clamped on the fourth gear 23 of the product self-rotation module 4. Second, the coordinate positions corresponding to the heat shrinkage of the heat shrinkable tube of this specification are input into the computer. The PLC is communicatively connected to the computer, and the PLC controls the motor to act, so that the part of the heat shrinkable tube that needs to be heat shrunk and the air outlet of the hot air gun move to the corresponding positions according to the coordinate positions. Third, the hot air gun blows hot air on the part of the heat shrinkable tube 3 that needs to be heat shrunk for heat shrinkage operation. Fourth, after the heat shrinkage operation is completed, the product self-rotation module 4 stops working, and the PLC controls the sliders of the X axis motion module 5, the Y axis motion module 6, and the Z axis motion module 2 to return to their corresponding origin positions respectively, waiting for the next heat shrinkage operation.

[0004] However, in the above solution, it is necessary to sleeve the heat shrinkable tube onto the wire and then place it on the fourth gear 23 of the self-rotation module 4. The heat shrinkable tube is heated by the hot air gun 1 located above the self-rotation module 4, and the self-rotation module 4 cooperates to drive the heat shrinkable tube and the wire to rotate, so as to realize the heat shrinkage of each area of the heat shrinkable tube. However, this method requires multiple motion mechanisms to cooperate, which not only makes the motion structure complex, but also makes it difficult to achieve uniform shrinkage and stable fitting of the heat shrinkable tube during heat shrinkage processing. Secondly, the self-rotation module 4 is used to position the heat shrinkable tube and the wire, and only one can be processed at a time, with low efficiency, and the overall mechanism is complex and the cost is high.
