Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic extruders, in particular to a plastic processing and extrusion device. Background Technique
[0002] The plastic processing and extrusion device is also called a plastic extruder. The plastic extruder is a device that makes various cross-section products or semi-finished products through steps such as heating, melting, extruding, and forming plastic raw materials. In plastic processing, it is usually called extrusion forming or extrusion molding. If the plastic products formed at high temperature are directly exposed to the air for natural cooling, they may have deformation phenomena such as bending and depression due to uneven cooling. Therefore, during the production process of plastic pipes, the cooling system in the plastic extruder can timely cool down the formed plastic finished pipes, thereby shortening the production cycle, improving production efficiency, and preventing deformation and other situations.
[0003] When most existing plastic extruders produce plastic pipes, their finished product cooling systems cool the extruded plastic pipes by continuously spraying water on the surface of the plastic pipes, thereby cooling them. However, this cooling method not only requires continuous supply of sprayed water, resulting in waste of water resources, but also the sprayed water will splash when it falls on the plastic pipes, and then the sprayed water contacts the plastic pipes unevenly, resulting in uneven cooling.
[0004] For this reason, a plastic processing and extrusion device is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to provide a plastic processing and extrusion device to solve the problem that when most existing plastic extruders produce plastic pipes, their finished product cooling systems cool the extruded plastic pipes by continuously spraying water on the surface of the plastic pipes, thereby cooling them. However, this cooling method not only requires continuous supply of sprayed water, resulting in waste of water resources, but also the sprayed water will splash when it falls on the plastic pipes, and then the sprayed water contacts the plastic pipes unevenly, resulting in uneven cooling.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A plastic processing and extrusion device includes an extruder body, and a bracket is fixedly connected to one side of the extruder body; a cooling component for the plastic pipes for extrusion molding is arranged on the bracket. The cooling component includes two rotating wheels arranged on one side of the extruder body for soaking the plastic pipes with moisture, and wiping cotton for adhering moisture is arranged in both of the two rotating wheels; a switch component for intermittent water supply is also arranged on the rotating wheels. The switch component includes a bent plate fixedly connected to the top of the rotating wheel, and an arc plate for cooperating with the bent plate to supply water is arranged on one side of the bent plate.
[0007] Preferably, a connecting plate is fixedly connected to the bracket, a rotating shaft is rotatably connected between the connecting plate and the rotating wheel, and the plastic pipe extruded and formed by the extruder body is in close contact with the wiping cotton between the two rotating wheels.
[0008] Preferably, a water tank for cooling and providing moisture is fixedly installed on the bracket, a fixed pipe for draining water is fixedly connected to the bottom end of the water tank, a movable pipe is slidably connected in the fixed pipe, and the arc plate is fixedly connected to the movable pipe.
[0009] Preferably, a circular plate is fixedly connected to the movable pipe, and a spring is fixedly connected between the circular plate and the end of the fixed pipe. A receiving groove is provided in the fixed pipe, and a discharge port is provided in the movable pipe, and the discharge port is located in the receiving groove.
[0010] Preferably, a water distribution pipe capable of conveying moisture to the tops of the two rotating wheels is slidably connected to the movable pipe, and the water distribution pipe is fixed to the bracket through a bent plate. A nozzle for spraying moisture is fixedly connected to the water distribution pipe.
[0011] Preferably, the end of the bent plate is provided with an arc shape, the arc plate is provided with an arc surface adapted to the arc shape of the end of the bent plate, and a notch for the passage of moisture is provided in the bent plate.
[0012] Preferably, a surrounding plate is fixedly connected to the rotating wheel, a plurality of through holes are provided at the top of the rotating wheel, and a recycling box is provided on the bracket.
[0013] The beneficial effects of the present utility model:
[0014] With the cooperation of the cooling component and the switch component provided in the present utility model, when the extruder body extrudes and forms a pipe, the rotating wheel can be driven to rotate. Thus, under the combined action of the bent plate and the arc plate, the discharge port on the movable pipe enters the inner cavity of the fixed pipe. Furthermore, the moisture in the water tank can be discharged through the nozzle to the rotating wheel, and the moisture flows into the wiping cotton through the through holes. Thus, the wet wiping cotton cools the pipe. The rotation of the rotating wheel will also cause the bent plate to disengage from the arc plate. Thus, under the reaction force of the spring, the movable pipe is reset, and further the moisture cannot be sprayed out through the nozzle. The whole device intermittently circulates water supply and cooling in this way, enabling the moisture to flow into the wiping cotton directionally, reducing waste and saving water resources. At the same time, the wet wiping cotton makes more uniform contact with the pipe when wiping, so that the moisture contacts the pipe more evenly, making the cooling more uniform.

[0023] As Figures 1 to 4 shown, a specific embodiment of the present utility model provides a plastic processing and extrusion device, including an extrusion machine body 1, and a bracket 2 is fixedly connected to one side of the extrusion machine body 1; a cooling component for the plastic pipe for extrusion molding is provided on the bracket 2. By setting the cooling component, the plastic pipe extruded and molded in the extrusion machine body 1 can be cooled more quickly, thereby preventing phenomena such as bending and deformation caused by uneven natural cooling. The cooling component includes two rotating wheels 3 provided on one side of the extrusion machine body 1 for wetting the plastic pipe with water, and wiping cotton 4 for adhering water is provided in both of the two rotating wheels 3; it also includes a switch component for intermittently supplying water provided on the rotating wheel 3. By setting the switch component, when cooling the pipe, the water supply method can be adjusted to intermittent water supply, so as to save water resources and avoid waste without affecting the cooling. The switch component includes a bending plate 5 fixedly connected to the top of the rotating wheel 3, and an arc plate 6 for cooperating with the bending plate 5 to supply water is provided on one side of the bending plate 5.
[0024] As Figures 1 to 4As shown, specifically, a connecting plate 7 is fixedly connected to the support 2. A rotating shaft is rotatably connected between the connecting plate 7 and the rotating wheel 3. The plastic pipe extruded and formed by the extruder body 1 is in close contact with the wiping cotton 4 between the two rotating wheels 3. When the extruder body 1 is working, the pipe extruded and formed by it moves outward. The pipe passes between the two rotating wheels 3, and drives the two rotating wheels 3 to rotate under the action of the moving friction of the pipe. The rotation of the rotating wheel 3 drives the bending plate 5 to rotate. A water tank 8 for cooling and providing moisture is fixedly installed on the support 2. A fixed pipe 9 for draining water is fixedly connected to the bottom end of the water tank 8. A movable pipe 10 is slidably connected in the fixed pipe 9, and the arc plate 6 is fixedly connected to the movable pipe 10. A circular plate 11 is fixedly connected to the movable pipe 10, and a spring 12 is fixedly connected between the circular plate 11 and the end of the fixed pipe 9. A receiving groove 13 is provided in the fixed pipe 9, and a discharge port 14 is provided in the movable pipe 10, and the discharge port 14 is located in the receiving groove 13. A water distribution pipe 15 that can convey moisture to the tops of the two rotating wheels 3 is slidably connected to the movable pipe 10, and the water distribution pipe 15 is fixed to the support 2 through a bent plate. A nozzle 16 for spraying moisture is fixedly connected to the water distribution pipe 15. The end of the bending plate 5 is provided with an arc shape, and an arc surface 17 adapted to the arc shape of the end of the bending plate 5 is provided on the arc plate 6. A notch 18 for the passage of moisture is provided on the bending plate 5. At this time, during the rotation of the bending plate 5, it contacts and rubs against the arc plate 6, and under the cooperation of the arc surface 17, the movable pipe 10 moves in the water distribution pipe 15 and the fixed pipe 9. The discharge port 14 on the movable pipe 10 moves out of the receiving groove 13 and moves into the inner cavity of the fixed pipe 9, and the movable pipe 10 drives the circular plate 11 to move, causing the spring 12 to be stressed and contract to generate a reaction force. After the discharge port 14 is located in the inner cavity of the fixed pipe 9, the moisture in the water tank 8 can enter the movable pipe 10 through the inner cavity of the fixed pipe 9 and the discharge port 14, then reach the water distribution pipe 15 through the movable pipe 10, and finally be sprayed downward through the nozzle 16.
[0025] As Figures 1 to 4As shown, specifically, a shroud 19 is fixedly connected to the runner 3. A number of through holes 20 are provided at the top of the runner 3. A recovery box 21 is provided on the bracket 2. The water sprayed downward by the nozzle 16 falls onto the tops of the two runners 3. Under the limiting action of the shroud 19, the water at the top of the runner 3 is not likely to flow out, and the water flows into the wiping cotton 4 in the runner 3 through the through holes 20, thereby wetting the wiping cotton 4. At the same time, the wet wiping cotton 4 can wipe and cool the passing pipeline. The wiping cotton 4 makes contact with the pipeline more evenly, so that the water contacts the pipeline more evenly, making the cooling more uniform. When the bending plate 5 rotates and disengages from the arc plate 6 and no longer contacts it, the movable pipe 10 moves back to its original position under the reaction force of the spring 12. Thus, the discharge port 14 on the movable pipe 10 re-enters the receiving groove 13. At this time, the water in the water tank 8 cannot enter the discharge port 14 through the fixed pipe 9, so it cannot flow to the nozzle 16 and spray outwards. Furthermore, the water supply to the wiping cotton 4 in the runner 3 is suspended. The wiping cotton 4 has water absorption by itself, so it will temporarily maintain a short-term wetness, and its wetness is sufficient to cool its pipeline. During the process of the runner 3 driving the bending plate 5 to rotate in a cycle, the water in the water tank 8 will flow to the wiping cotton 4 again, thereby wetting the wiping cotton 4 again so that it can cool the pipeline. The whole process can form a cycle of water supply and cooling, saving water resources. The setting of the notch 18 enables the water sprayed by the nozzle 16 to reach the runner 3 with less obstruction by the bending plate 5. And the dripping water generated during the whole cooling process will be collected by the recovery box 21 at the bottom.
