Description

Technical Field

[0001] The utility model relates to the technical field of dry expanders, in particular to a heat shrink tube dry expander. Background Art

[0002] Heat shrink tube dry expander is a kind of equipment used for heat shrink tube processing. It expands the heat shrink tube by dry heating. Compared with the traditional wet heating which usually uses glycerin as the heating medium, the dry expander does not need to use any processing liquid, so it is more environmentally friendly and does not produce odor. This kind of machine usually has higher processing efficiency and lower operating costs.

[0003] When using the existing heat shrink tube dry expander, the heat shrink tube is heated by a heating device, and then put on the expansion head of the dry expander to expand the heat shrink tube. The heated heat shrink tube easily adheres to the surface of the expansion head, making it difficult to remove the heat shrink tube, reducing practicality. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a heat shrink tube dry expander.

[0005] The utility model is implemented by the following technical scheme: a heat shrink tube dry expander, comprising a cooling box, an expansion assembly is arranged at the upper end of the cooling box, a mounting frame is fixedly connected to the top of the cooling box, a hydraulic rod is fixedly connected to the inner wall of the mounting frame, a mounting plate is fixedly connected to the bottom of the hydraulic rod, and a driving assembly is arranged at the right end of the mounting plate;

[0006] The expansion assembly includes an expansion plate, an inner wall of the expansion plate is fixedly connected to a fixing rod, an end of the fixing rod away from the expansion plate is fixedly connected to a fixing block, an inner wall of the fixing block is rotatably connected to a movable plate, an end of the movable plate away from the fixing block is rotatably connected to the fixing plate, one end of the fixing plate is fixedly connected to a nut seat, an inner wall of the nut seat is threadedly connected to a bidirectional screw rod, the left end of the bidirectional screw rod is fixedly connected to a limiting block, and the inner wall of the nut seat is slidably connected to the limiting rod.

[0007] Through the above technical solution, the bidirectional screw is driven to rotate by the driving assembly, so that the two nut seats move closer to each other, and the movable plate rotates on the inner wall of the fixed block and the fixed plate, so that the angle of the movable plate changes, and the expansion plate is pushed to move, which makes it easier to expand the heat shrink tube into different sizes and improves practicality.

[0008] As a further improvement of the above solution, there are two expansion plates, the right end of the nut seat is fixedly connected to the left end of the mounting plate, and there are two nut seats, which are symmetrically distributed around the bidirectional screw rod.

[0009] As a further improvement of the above solution, the number of the hydraulic rods is two, and the two hydraulic rods are symmetrically distributed around the mounting frame.

[0010] Through the above technical solution, the mounting plate is pushed downward by the hydraulic rod, so that the heat shrink tube contacts the water inside the cooling box to achieve cooling, making it easier to remove the heat shrink tube. The stability of the mounting plate when moving is improved by the two hydraulic rods.

[0011] As a further improvement of the above scheme, the driving assembly includes a motor, the output end of the motor is fixedly connected to a transmission shaft, the surface of the transmission shaft is fixedly connected to a first bevel gear, a second bevel gear is provided at the lower end of the first bevel gear, a transmission rod is fixedly connected to the inner wall of the second bevel gear, and the top of the motor is fixedly connected to a fixed seat.

[0012] Through the above technical solution, the motor drives the transmission shaft to rotate, so that the first bevel gear rotates, drives the second bevel gear to rotate, and thus drives the transmission rod to rotate, so that the bidirectional lead screw rotates.

[0013] As a further improvement of the above solution, the first bevel gear and the second bevel gear are meshed with each other, and the left end of the transmission rod is fixedly connected to the right end of the bidirectional lead screw.

[0014] With the above technical solution, by providing the first bevel gear and the second bevel gear, it is prevented that when the mounting plate moves downward, the motor is damaged by contact with water inside the cooling box.

[0015] As a further improvement of the above solution, the surface of the transmission rod is rotatably connected to the inner wall of the mounting plate, and the left end of the fixing seat is fixedly connected to the right end of the mounting plate.

[0016] As a further improvement of the above solution, sliders are fixedly connected to both ends of the mounting plate, a slide groove is provided on the inner wall of the cooling box, and the surface of the slider is slidably connected to the inner wall of the slide groove.

[0017] Through the above technical solution, the slider slides on the inner wall of the slide groove, so that the installation plate is more stable when moving.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The utility model provides a mounting frame, a hydraulic rod, a mounting plate and a slide block. Specifically, the hydraulic rod pushes the mounting plate to move downward, so that the slide block slides downward on the inner wall of the slide groove, thereby improving the stability of the mounting plate when moving, and allowing the heat shrink tube sleeved on the surface of the mounting plate to enter the interior of the cooling box and contact with the water source for cooling, which is convenient for subsequent removal of the heat shrink tube, thereby improving the efficiency of heat shrink tube processing.

[0020] The utility model provides an expansion component and a driving component, specifically, the driving component drives the bidirectional screw rod to rotate, so that the two nut seats move closer to each other, so that the movable plate rotates on the inner wall of the fixed block and the fixed plate, so that the angle of the movable plate changes, thereby pushing the expansion plate to move upward, expanding the heated heat shrink tube, ensuring the stability and accuracy of the heat shrink tube during the expansion process, making it easy to expand the heat shrink tube into different sizes, and improving convenience during use.
