Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, and in particular to a cooling device for the production of modified plastics. Background Technology

[0002] Modified plastics refer to polymeric materials that have been modified and processed based on general-purpose plastics and engineering plastics through techniques such as filling and blending to significantly improve their properties such as flame retardancy, strength, and heat resistance. Cooling during plastic extrusion is a key step in ensuring product quality and production efficiency.

[0003] A search revealed a Chinese patent publication number CN222891624U, which discloses a modified PP plastic wire extrusion cooling device. This patent guides the plastic wire using a first guide roller, then passes the plastic wire sequentially through multiple movable rods for support and lead-in. Subsequently, a take-up roller is rotated to allow the plastic wire to pass through a water storage tank for cooling. However, this device has a certain problem: when the plastic wire passes through the water storage tank for cooling, the water in the tank gradually heats up over time, reducing the cooling effect and making it impossible to remove the heat in time. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for the production of modified plastics in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A cooling device for modified plastic production includes a cooling platform, an extrusion box fixedly connected to one side of the cooling platform, an upward sloping section on the side of the cooling platform near the extrusion box, a water tank located below the cooling platform, and a circulation mechanism between the water tank and the cooling platform.

[0007] The circulation mechanism includes a delivery pump, which is fixedly installed on the water tank. A fixed pipe is fixedly connected to the end of the cooling platform near the extrusion box. A connecting pipe is fixedly connected between the fixed pipe and the delivery pump. A tee pipe is fixedly connected to the end of the water tank away from the extrusion box. The upper end of the tee pipe is fixedly connected to the cooling platform. A cooling pipe is fixedly installed inside the water tank.

[0009] Preferably, multiple combing teeth are arranged at equal intervals along the axial direction of the roller shaft, and a power motor is fixedly installed at the front end of the cooling table, with the output shaft of the power motor fixedly connected to the roller shaft.

[0010] Preferably, the inner wall of the cooling platform is fixedly connected to multiple connecting columns, the connecting columns are rotatably connected to rotating plates, the end of the rotating plate away from the connecting columns is rotatably connected to a pressure roller, and the two ends of the pressure roller are fixedly connected to limit plates.

[0012] Preferably, multiple extrusion tubes are fixedly connected to the side of the extrusion box near the cooling platform, and the multiple extrusion tubes are arranged at equal intervals.

[0013] Preferably, a chiller is fixedly installed at the rear end of the water tank.

[0014] The beneficial effects are as follows: water flows out of the fixed pipe and passes through the inclined section. When the plastic line comes into contact with the water in the inclined section, it begins to cool the plastic line. At the same time, as the water moves the plastic line away from the extrusion box, the water in the cooling platform enters the cooling pipe through the three-way pipe for further cooling.

Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a cooling device for the production of modified plastics includes a cooling platform 101, an extrusion box 102 is fixedly connected to one side of the cooling platform 101, the side of the cooling platform 101 near the extrusion box 102 is an upward sloping section, a water tank 103 is provided below the cooling platform 101, and a circulation mechanism is provided between the water tank 103 and the cooling platform 101.

[0027] The circulation mechanism includes a delivery pump 401, which is fixedly mounted on a water tank 103. A fixed pipe 402 is fixedly connected to one end of the cooling platform 101 near the extrusion chamber 102. A connecting pipe 403 is fixedly connected between the fixed pipe 402 and the delivery pump 401. A three-way pipe 404 is fixedly connected to one end of the water tank 103 away from the extrusion chamber 102. The upper end of the three-way pipe 404 is fixedly connected to the cooling platform 101. A cooling pipe 405 is fixedly installed inside the water tank 103. The cooling pipe 405 is spiral-shaped, and its two ends are respectively connected to the three-way pipe 403. 4. Connected to the connecting pipe 403, the delivery pump 401 delivers water from the water tank 103 to the fixed pipe 402 through the connecting pipe 403. Then, the water flows out from the fixed pipe 402 and passes through the inclined section. Then, the extrusion box 102 extrudes the plastic line. The plastic line contacts the water in the inclined section and begins to cool the plastic line. At the same time, the gravitational potential energy of the water is converted into kinetic energy, which drives the plastic line away from the extrusion box 102. Meanwhile, the water in the cooling platform 101 enters the cooling pipe 405 through the three-way pipe 404 for further cooling. The cooled water is then sprayed out through the fixed pipe 402.

[0028] A combing mechanism is provided on the side of the cooling table 101 away from the extrusion box 102. The combing mechanism includes a roller 201, which is rotatably connected inside the cooling table 101. Multiple combing teeth 202 are fixedly connected on the roller 201. The plastic line is wrapped around the roller 201 and combed by the multiple combing teeth 202 to prevent the plastic line from getting tangled together during subsequent winding.

[0029] Multiple combing teeth 202 are arranged at equal intervals along the axial direction of roller shaft 201. A power motor 203 is fixedly installed at the front end of cooling table 101. The output shaft of power motor 203 is fixedly connected to roller shaft 201, and the roller shaft 201 is driven to rotate by power motor 203.

[0030] Multiple connecting columns are fixedly connected to the inner wall of the cooling platform 101. A rotating plate 301 is rotatably connected to the connecting columns. A pressure roller 302 is rotatably connected to the end of the rotating plate 301 away from the connecting columns. Limiting disks 303 are fixedly connected to both ends of the pressure roller 302.

[0031] A fixing post 502 is provided on one side of the rotating plate 301. The fixing post 502 is fixedly installed on the inner wall of the cooling platform 101. The front end of the connecting post is threaded with a locking cover 501. Initially, the rotating plate 301 abuts against the fixing post 502, so that the pressure roller 302 is away from the water surface. When the plastic line enters the water, the rotating plate 301 is rotated to press the plastic line into the water through the pressure roller 302 to avoid insufficient cooling of the plastic line. Then the locking cover 501 is rotated to squeeze the rotating plate 301 and fix the position of the pressure roller 302.

[0032] Multiple extrusion tubes 6 are fixedly connected to one side of the extrusion box 102 near the cooling platform 101. The multiple extrusion tubes 6 are arranged at equal intervals, and the molten and mixed modified plastic is extruded into plastic lines through the multiple extrusion tubes 6.

[0033] A refrigeration unit is fixedly installed at the rear end of the water tank (103). The evaporator of the refrigeration unit is in contact with the water tank (103). The refrigeration unit is equipped with a compressor, a condenser and an evaporator. The low-pressure refrigerant in the evaporator absorbs heat and vaporizes into low-temperature steam, so that the evaporator of the refrigeration unit cools the coolant in the water tank (103), and the coolant cools the water in the cooling pipe 405.

[0034] Working principle: During use, the delivery pump 401 delivers water from the water tank 103 to the fixed pipe 402 through the connecting pipe 403. The water then flows out of the fixed pipe 402 and passes through the inclined section. The extrusion box 102 then extrudes the molten and mixed modified plastic into plastic lines through multiple extrusion pipes 6. The plastic lines contact the water in the inclined section, which begins to cool them. Simultaneously, the gravitational potential energy of the water is converted into kinetic energy, causing the plastic lines to move away from the extrusion box 102. Initially, the rotating plate 301 abuts against the fixed column 502, keeping the pressure roller 302 away from the water surface. Once the plastic lines enter the water, rotating the rotating plate 301 presses the plastic lines into the water through the pressure roller 302, preventing insufficient cooling. Then, rotating the locking cover 501 causes it to press against the rotating plate. The moving plate 301 fixes the position of the pressure roller 302, and the plastic thread is wrapped around the roller shaft 201. The roller shaft 201 is driven to rotate by the power motor 203. The plastic thread is combed by multiple combing teeth 202 to prevent the plastic thread from getting tangled during subsequent winding. At the same time, the water in the cooling table 101 enters the cooling pipe 405 through the three-way pipe 404. The evaporator of the refrigeration machine is in contact with the water tank 103. The refrigeration machine is equipped with a compressor, condenser and evaporator. The low-pressure refrigerant in the evaporator absorbs heat and vaporizes into low-temperature steam, so that the evaporator of the refrigeration machine cools the coolant in the water tank 103, so that the coolant cools the water in the cooling pipe 405. The cooled water is then sprayed out through the fixed pipe 402 to ensure the cooling effect of the plastic thread.
