[0051] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0052] like Figure 1-4 As shown, a heat shrink tube winding device comprises:

[0053] Rack 1;

[0054] Two transmission rollers 2, which are rotatably mounted on the frame 1;

[0058] The squeezing roller height adjustment mechanism 4 is suitable for driving the squeezing roller 5 to move up and down through the height adjustment slider;

[0059] The driving roller 2 is adapted to cooperate with the squeezing roller 5 to form an squeezing channel;

[0060] The transmission roller driving mechanism 3 is suitable for driving the transmission roller 2 to drive the heat shrink tube to pass through the extrusion channel;

[0061] A winding roller 6, which is rotatably mounted on the frame 1;

[0062] A winding roller driving mechanism 7, the winding roller driving mechanism 7 is fixed on the frame 1, and the winding roller driving mechanism 7 is suitable for driving the winding roller 6 to rotate and wind up the heat shrinkable tube after passing through the extrusion channel;

[0063] A cooling water medium circulation channel 51 is provided in the extrusion roller 5, and a water inlet and a water outlet connected to the cooling water medium circulation channel 51 are provided at both ends of the extrusion roller 5;

[0064] An air-cooling heat dissipation mechanism 8, which is mounted on the frame 1 and is suitable for performing air cooling and heat dissipation on the squeezing roller 5;

[0065] The water-cooled circulating heat dissipation mechanism 9 is installed in the frame 1. The water-cooled circulating heat dissipation mechanism 9 is provided with a water supply port and a water return port. The water return port is connected with the water outlet of the squeezing roller 5, and the water supply port is connected with the water inlet of the squeezing roller 5. The water-cooled circulating heat dissipation mechanism 9 is suitable for driving the cooling water to circulate through the cooling water medium flow channel 51 of the squeezing roller 5.

[0066] In this embodiment, if Figure 1-2 As shown, the heat shrink tube first passes through an extrusion channel formed by a drive roller 2 and an extrusion roller 5 before entering the winding process. The uniform extrusion of the extrusion channel ensures the flatness of the heat shrink tube and the quality of the winding. In addition, during the extrusion process, the air-cooled heat dissipation mechanism 8 is responsible for external heat dissipation of the extrusion roller 5, while the water-cooled circulating heat dissipation mechanism 9 drives the circulating cooling water to flow in the cooling water medium flow channel of the extrusion roller, effectively realizing the heat management generated during the high-speed winding process, and ensuring that the equipment can operate stably for a long time. Finally, the winding roller 6 is driven by the winding roller drive mechanism 7 to complete the winding work.

[0067] In some embodiments, the number of the driving rollers 2 and the squeezing roller height adjustment mechanisms 4 is not limited to two and can be set according to specific requirements.

[0068] Specifically, Figure 1-2 As shown, the heat shrink tube winding device also includes a guide roller group, which is arranged on the conveying path between the extrusion channel and the winding roller 6;

[0069] The guide roller group is suitable for guiding the heat shrink tube from the extrusion channel to be wound on the winding roller 6.

[0070] Specifically, Figure 1-2 As shown, the guide roller group can be the following structure, including:

[0071] A first guide roller 110, which is rotatably mounted on the frame 1, and a pulley is provided at one end of the first guide roller 110, and the first guide roller 110 is suitable for being connected to the transmission roller 2 through a belt;

[0072] A third guide roller 130, the third guide roller 130 is rotatably mounted on the frame 1, and the axis of the third guide roller 130 and the axis of the winding roller 6 are located in the same horizontal plane;

[0073] The second guide roller 120 is rotatably mounted on the frame 1 , and the second guide roller 120 is arranged between the first guide roller 110 and the third guide roller 130 .

[0074] In this embodiment, if Figure 1-2 As shown, the function of the guide roller group is to guide the heat shrink tube processed through the extrusion channel to be smoothly transferred to the winding roller 6 for winding.

[0075] The first guide roller 110 can be driven to rotate by the power of the driving roller 2. When the heat shrink tube comes out of the extrusion channel, it will first bypass the first guide roller 110 to change the direction of movement. The axis of the third guide roller 130 is on the same horizontal plane as the axis of the winding roller 6, which can reduce the angle at which the heat shrink tube enters the winding roller 6 and facilitate winding.

[0076] Specifically, Figure 1-2 and Figure 4 As shown, the water-cooling circulation heat dissipation mechanism 9 includes a water tank and a water pump mounted on the frame 1;

[0077] The water tank is provided with a water return port and a water outlet, and the water return port of the water tank is connected with the water outlet of the squeezing roller 5;

[0078] The water pump is provided with a water inlet and a water supply port. The water inlet of the water pump is connected to the water outlet of the water tank, and the water supply port of the water pump is connected to the water inlet of the squeezing roller 5. The water pump is suitable for pumping the cooling water of the water tank into the cooling water medium circulation channel 51 of the squeezing roller 5.

[0079] Specifically, Figure 1-2 As shown, the water-cooled circulating heat dissipation mechanism 9 also includes a radiator, which is mounted on the frame 1 and is arranged in close contact with the air-cooled heat dissipation mechanism 8. The radiator is provided with a water inlet and a water outlet. The water inlet of the radiator is connected to the water outlet of the squeezing roller 5, and the water outlet of the radiator is connected to the water return port of the water tank.

[0080] The radiator is suitable for cooling the cooling water flowing through it through the air-cooling heat dissipation mechanism 8 .

[0081] In this embodiment, if Figure 1-2 and Figure 4 As shown, the water tank is made of stainless steel, and is provided with a liquid level gauge extending to the outside. The water inlet and outlet are designed with quick connectors for easy disassembly and maintenance.

[0082] The water tank is used as a container for storing and temporarily storing cooling water, and its water return port is connected to the water outlet of the squeezing roller 5 for receiving the cooling water flowing out of the heat exchanger.

[0083] The water inlet of the water pump is connected to the water outlet of the water tank. The water pump sucks in and pressurizes the cooling water in the water tank, and delivers the high-pressure cooling water from the water supply port to the water inlet of the extrusion roller 5, and enters the cooling water medium flow channel 51 inside the extrusion roller 5 to cool the extrusion roller 5.

[0084] The high-temperature cooling water after passing through the squeezing roller 5 is discharged from the water outlet again and enters the water inlet of the heat exchanger.

[0085] The radiator is mounted on the frame 1 and is fitted with the fan portion of the air-cooling heat dissipation mechanism 8, and the fan can directly force air cooling on the surface of the radiator. Under the air cooling effect, the radiator quickly radiates the heat of the cooling water.

[0086] The low-temperature cooling water cooled by the radiator is discharged from the water outlet of the radiator and returns to the return water outlet of the water tank to form a circulation.

[0087] Among them, a filter and a flow meter are provided on the pipeline from the water outlet of the water pump to the water inlet of the squeezing roller 5 to filter impurities and monitor the flow.

[0088] Specifically, Figure 1-2 As shown, two driving rollers 2 are provided, and the two driving rollers 2 are symmetrically arranged on the frame 1 in the radial plane of the squeezing roller 5 .

[0089] In this embodiment, if Figure 1-2 As shown, two symmetrical driving rollers 2 are provided to make the force on the heat shrinkable tube in the extrusion channel more uniform and symmetrical, so as to avoid the heat shrinkable tube from twisting and deforming during the extrusion process.

[0090] The two driving rollers 2 are respectively located on both sides of the radial plane of the squeezing roller 5 and are symmetrical with the radial plane of the squeezing roller 5 as a symmetry plane.

[0091] Specifically, Figure 1-3 As shown, the squeezing roller height adjustment mechanism 4 may be of the following structure, including:

[0092] A mounting frame 41, the mounting frame 41 is fixed on the frame 1, and a linear guide groove is provided in the mounting frame 41;

[0093] A spiral lifting drive mechanism 42, the spiral lifting drive mechanism 42 is installed in the mounting frame 41;

[0094] A screw shaft 43, the screw shaft 43 is rotatably mounted in the mounting frame 41, and the screw shaft 43 is provided with an external thread;

[0095] A height adjustment slider 44, which is slidably disposed in a linear guide groove of the mounting frame 41, and is provided with an internal threaded hole, which is threadedly connected to the external thread of the lead screw shaft 43;

[0096] The height adjustment slider 44 is fixedly connected to one end of the corresponding squeezing roller 5;

[0097] The spiral lifting drive mechanism 42 is suitable for driving the height adjustment slider 44 to perform vertical displacement in the linear guide groove through the rotation of the screw shaft 43.

[0098] Specifically, Figure 1-3 As shown, the spiral lifting drive mechanism 42 is a servo motor.

[0099] In this embodiment, if Figure 1-2 As shown, the main function of the extrusion roller height adjustment mechanism is to adjust the height position of the extrusion roller 5 relative to the driving roller 2, thereby changing the gap size of the extrusion channel to meet the processing requirements of heat shrink tubes of different specifications.

[0100] The spiral lifting drive mechanism 42 drives the lead screw shaft 43 to rotate.

[0101] The rotation of the lead screw shaft 43 will mesh with the internal thread hole of the height adjustment slider 44 through its external thread, so that the height adjustment slider 44 performs a linear vertical motion in the linear guide groove.

[0102] The height-adjusting slider 44 is fixedly connected to one end of the squeezing roller 5 , so the squeezing roller 5 will also move up and down following the movement of the height-adjusting slider 44 .

[0103] By controlling the forward and reverse rotation of the spiral lifting drive mechanism 42 , the position of the height adjustment slider 44 can be accurately adjusted, thereby accurately adjusting the height of the squeezing roller 5 .

[0104] There are two squeezing roller height adjustment mechanisms 4 , which are arranged at both ends of the squeezing roller 5 .

[0105] Specifically, Figure 1-2 As shown, the air cooling heat dissipation mechanism 8 may have the following structure, including:

[0106] Three fans are installed on the frame 1 , and the air outlets of the fans face the squeezing roller 5 .

[0107] Specifically, Figure 1-2 As shown, the air-cooling heat dissipation mechanism 8 also includes an air filter, which is installed at the air inlet of the fan.

[0108] In this embodiment, if Figure 1-2 As shown, the air-cooling and heat dissipation mechanism 8 is used to cool the extrusion roller 5 to maintain the low temperature of the extrusion roller 5, thereby effectively preventing the heat shrink tube from being deformed due to excessive heat during the extrusion process.

[0109] The air outlet of the fan faces toward the squeezing roller 5 , so that when the fan is running, a forced convection airflow will be blown out to directly cool the outer surface of the squeezing roller 5 .

[0110] In addition, the air filter is used to filter dust particles in the incoming air to prevent these impurities from entering the fan and affecting the life of the fan, while also preventing the surface of the extrusion roller 5 from being contaminated.

[0111] In some embodiments, the number of fans is not limited to three and can be set according to specific needs.

[0112] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
