[0002] Low-smoke halogen-free flame-retardant tape is a type of fire-resistant insulating roll containing flame-retardant materials, which provides excellent flame-retardant effects and produces less smoke during combustion. During the production of low-smoke halogen-free flame-retardant tape, a cooling and shaping device is required to cool and shape the tape. Currently, flame-retardant tape is generally cooled and shaped using air cooling, but the amount of heat carried away by the airflow is limited, resulting in less than ideal cooling effect and efficiency. Utility Model Content

It solves the problem that flame-retardant tapes are generally cooled and shaped by air cooling, but the amount of heat carried away by the air is small, resulting in an unsatisfactory cooling effect and efficiency.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-efficiency cooling and shaping device for the production of low-smoke halogen-free flame-retardant tape, comprising a machine body, with material inlets at both ends of the machine body, a double-sided cooling mechanism inside the machine body, and a winding mechanism on one side of the machine body;
[0005] The double-sided cooling mechanism includes a chiller. Two movable seats are provided on one side of the chiller. A nut seat is fixedly connected to one end of each movable seat, and a guide seat is fixedly connected to the other end of each movable seat. A guide rod is provided between the two guide seats.

Cooling channels are opened inside the cooling rollers. Rotary joints are installed at both ends of the cooling rollers. An inlet pipe and an outlet pipe are respectively provided at both ends of the cooling rollers.
[0006] Preferably, the chiller is installed outside the machine body and is detachably connected to the machine body, which makes it convenient to maintain the chiller.
[0007] Preferably, the bidirectional screw is rotatably connected to the inner wall of the machine body, and the bidirectional screw is provided with two sections of threads in opposite directions, so that the bidirectional screw can simultaneously drive the two nut seats to move towards or away from each other.
[0008] Preferably, the guide rod is fixedly connected to the inner wall of the machine body, and the guide rod is slidably connected to the guide seat, so as to guide the movement of the guide seat.
[0009] Preferably, the two cooling rollers are symmetrically arranged on the opposite surfaces of the two movable seats, and both cooling rollers are made of a high thermal conductivity metal material, which can effectively improve the heat conduction and heat exchange effect.
[0010] Preferably, one end of the inlet pipe and the outlet pipe are connected to the cooling roller via a rotary joint, and the other end of the inlet pipe and the outlet pipe are connected to a chiller, so that the chiller can continuously supply cooling water to the inside of the cooling roller.
[0011] Preferably, the winding mechanism includes a fixed frame and a movable frame, with a winding roller inserted between the fixed frame and the movable frame.

[0012] This invention provides a high-efficiency cooling and shaping device for the production of low-smoke halogen-free flame-retardant tape. Compared with the prior art, it has the following advantages:
[0013] 1. This high-efficiency cooling and shaping device for the production of low-smoke halogen-free flame-retardant tape uses a drive motor to move the cooling rollers, causing the two cooling rollers to move towards each other and come into contact with both sides of the flame-retardant tape. Then, a chiller continuously supplies cooling water into the cooling rollers through the water inlet pipe. The cooling water lowers the temperature of the cooling rollers. Compared with air cooling, this direct contact heat exchange method effectively improves the cooling effect and efficiency.
[0014] 2. The high-efficiency cooling and shaping device for the production of low-smoke halogen-free flame-retardant tape uses a winding motor to drive the winding roller to rotate, thereby winding the flame-retardant tape.

The double-sided cooling mechanism 2 can simultaneously cool and shape both sides of the flame-retardant tape. Compared with air cooling, the direct contact heat exchange method is used for cooling, which effectively improves the cooling effect and efficiency.
[0022] The double-sided cooling mechanism 2 includes a chiller 201, which is installed outside the body 1. The chiller 201 is detachably connected to the body 1, allowing for convenient maintenance. Two movable seats 202 are provided on one side of the chiller 201.

A guide rod 207 is provided between the two guide seats 204, and the guide rod 207 is fixedly connected to the inner wall of the body 1. The guide seat 204 is slidably connected to the guide seat 204, which guides the movement of the guide seat 204. A double-acting screw 205 is threaded between the two nut seats 203. The double-acting screw 205 is rotatably connected to the inner wall of the machine body 1. The double-acting screw 205 has two sections of threads in opposite directions, which allows the double-acting screw 205 to simultaneously drive the two nut seats 203 to move towards or away from each other. A drive motor 206 is fixedly connected to the top of the double-acting screw 205. Rotary seats 208 are fixedly connected to the opposite surfaces of the two movable seats 202. Cooling rollers 209 are rotatably connected inside each rotating seat 208. Both cooling rollers 209 can simultaneously contact both sides of the flame-retardant strip to cool and shape it. The two cooling rollers 209 are symmetrically arranged on the opposite surfaces of the two movable seats 202, and both are made of a high thermal conductivity metal material, such as copper or aluminum, effectively improving heat conduction and exchange. Multiple pairs of cooling rollers 209 can be arranged according to actual production needs, allowing for multiple cooling cycles and improving the cooling effect. The cooling roller 209 is provided with a cooling channel 210. Rotary joints 211 are installed at both ends of the cooling roller 209. Water inlet pipe 212 and water outlet pipe 213 are respectively provided at both ends of the cooling roller 209. One end of the water inlet pipe 212 and water outlet pipe 213 are connected to the cooling roller 209 through the rotary joint 211, so that the cooling water can flow continuously when the cooling roller 209 is rotating. The other end of the water inlet pipe 212 and water outlet pipe 213 are connected to the chiller 201, so that the chiller 201 can continuously supply cooling water to the interior of the cooling roller 209.
[0023] Please see Figure 1 and Figure 4The winding mechanism 4 includes a fixed frame 401 and a movable frame 402. A winding roller 403 is inserted between the fixed frame 401 and the movable frame 402. One end of the winding roller 403 has a D-shaped groove 405. A winding motor 404 with a D-shaped shaft is fixedly installed on the fixed frame 401, so that the D-shaped shaft on the winding motor 404 can be inserted into the D-shaped groove 405, thereby driving the winding motor 404 to rotate. A guide rail 407 is slidably connected to the bottom end of the movable frame 402. The guide rail 407 is fixedly installed on the machine body 1. A hydraulic cylinder 406 is fixedly connected to one side of the movable frame 402. The winding roller 403 can be driven to rotate by the winding motor 404, and the flame-retardant tape is wound up by the winding roller 403, which makes it easy to wind up the flame-retardant tape. Then, the hydraulic cylinder 406 drives the movable frame 402 to move, releasing the constraint on the winding roller 403, which makes it easy to replace the winding roller 403.
[0024] During operation, the drive motor 206 drives the bidirectional screw 205 to rotate. The rotation of the bidirectional screw 205 drives the nut seat 203 to move. The movement of the nut seat 203 drives the movable seat 202 to move. The movement of the movable seat 202 drives the cooling roller 209 to move, so that the two cooling rollers 209 move towards each other, allowing the cooling rollers 209 to contact both sides of the flame-retardant strip. Then, the chiller 201 continuously supplies cooling water into the cooling rollers 209 through the water inlet pipe 212, and the water flows back to the chiller 201 through the water outlet pipe 213 for cooling. The cooling water lowers the temperature of the cooling rollers 209. Compared with the air cooling method, the direct contact heat exchange method effectively improves the cooling effect and efficiency.
