[0002] Extrusion mechanism is a device that converts plastic raw materials into finished products of various shapes through a series of complex process. It is widely used in the manufacture of plastic products, such as plastic bags, plastic pipes, plastic plates, plastic strips, etc., especially in the fields of plastic films and plastic rolls. In addition, extrusion mechanism is also used in the preparation of materials in the construction field, such as PVC window frames, aluminum-plastic panels, plastic partitions, etc., as well as the packaging industry, such as food packaging, cosmetic containers, medical device packaging, etc.

[0003] When the extrusion mechanism is in use, in order to prevent impurities, metals and unmelted plastic particles from affecting product quality, a filter plate is added inside. However, the filter plate inside the mechanism is time-consuming and laborious to replace, which will cause the production line to be shut down for a long time, resulting in reduced production efficiency. At the same time, the difficulty in replacing the filter plate will also increase the corresponding maintenance cost. Utility Model Content

[0025] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a PVC sheet heating extrusion mechanism, comprising a dehumidification mechanism 1, the bottom of the dehumidification mechanism 1 is fixedly connected to a replacement mechanism 2;

[0026] The replacement mechanism 2 includes a bottom plate 201, four universal wheels 202 are fixedly installed at the bottom of the bottom plate 201, two support frames 203 are fixedly installed at the top of the bottom plate 201, a conveyor 204 is fixedly installed between the inner surface walls of the two support frames 203, an extruder 205 is fixedly connected to the output end of the conveyor 204, a base 206 is fixedly installed at the bottom of the extruder 205, the bottom of the base 206 is fixedly connected to the top of the bottom plate 201, an extrusion port 207 is opened on the outer wall of the extruder 205, and the inner surface of the extruder 205 is fixedly connected to the outer surface of the extruder 205. A mounting frame 208 is movably inserted into the surface wall, and two mounting holes 209 are provided on the outer wall of the mounting frame 208, and filter plates 210 are fixedly inserted into the inner walls of the two mounting holes 209, and a rack 211 is fixedly installed on one side of the outer wall of the mounting frame 208, and a motor 212 is fixedly installed on the top of the base 206, and a rotating shaft 213 is fixedly installed on the output end of the motor 212, and a gear 214 is fixedly sleeved on the outer wall of the rotating shaft 213, and the outer wall of the gear 214 is meshingly connected with the inner wall of the rack 211.

[0027] The effect achieved by the entire embodiment 1 is that after the conveyor 204 is started, it will drive the internal plastic particles to move forward. The plastic particles will be melted during the forward process. Subsequently, impurities, metals and unmelted particles inside the molten plastic will be removed by the filter plate 21 and extruded through the extrusion port 207. When the filter plate 210 needs to be replaced after being used for too long, it is only necessary to start the motor 212 so that the motor 212 drives the rotating shaft 213 and the gear 214 to rotate together. The gear 214 will move the rack 211 to one side, pull the mounting frame 208 to slide inside the extruder 205, and at the same time insert the unused filter plate 210 into a suitable position inside the extruder 205, quickly complete the replacement of the filter plate 210, and at the same time take the used filter plate 210 out of the extruder 205, so that it is convenient for workers to clean or replace it.

[0028] Embodiment 2, as Figure 2-Figure 4 As shown, the dehumidification mechanism 1 includes a processing tank 101, a feed port 102 is provided on the top of the processing tank 101, a circular hole 103 is fixedly installed on the top of the processing tank 101, a mounting hole 104 is opened on the top of the processing tank 101, a heating fan 105 is fixedly inserted into the inner surface wall of the mounting hole 104, a motor 106 is fixedly installed on the top of the processing tank 101, a rotating shaft 107 is fixedly installed on the output end of the motor 106, and the outer surface wall of the rotating shaft 107 is movably inserted in the inside of the circular hole 103, a group of stirring paddles 108 are fixedly installed on the outer surface wall of the rotating shaft 107, and a discharge valve 109 is provided at the bottom of the processing tank 101, and the output end of the discharge valve 109 is fixedly connected to the input end of the conveyor 204.

[0029] The effect achieved by the entire embodiment 2 is that the plastic particles can be poured into the processing tank 101 through the feed port 102, and then the equipment can be started. The heating fan 105 will heat the outside air and blow it into the processing tank 101 to remove the moisture inside the plastic particles. After the motor 106 is started, the plastic particles will be stirred by the rotating shaft 107 with the stirring paddle 108 to increase the contact area between the plastic particles and the hot air and improve the dehumidification effect. The discharge valve 109 can output the processed plastic particles. Removing the moisture inside the plastic particles can reduce the defective rate and improve product quality.

[0030] Working principle: workers first pour the plastic particles into the processing tank 101 through the feed port 102, and then the equipment can be started. At this time, the heating fan 105 starts to heat the outside air and blow it to the surface of the plastic particles inside the processing tank 101. Then the motor 106 also starts to drive the rotating shaft 107 to rotate inside the circular hole 103. When the rotating shaft 107 rotates, it will drive the stirring paddle 108 fixed on the outer wall to stir the plastic particles and remove the moisture inside the plastic particles. When the plastic particles are processed, the discharge valve 109 starts to start, so that the plastic particles inside the processing tank 101 fall into the conveyor 204. The motor of the conveyor 204 starts to drive the plastic particles forward through the internal dragon and the plastic particles are The particles are melted, and then the molten plastic is brought to the inside of the extruder 205 by the conveyor 204. The filter plate 210 will filter out impurities, metals and unmelted particles. The filtered plastic liquid is extruded through the extrusion port 207. When the worker needs to replace the internal filter plate 210, the motor 212 can be started. After the motor 212 is started, the shaft 213 will be driven to start rotating. When the shaft 213 rotates, the gear 214 fixedly mounted on the outer wall will be driven to rotate together. The gear 214 will move the rack 211 meshing with it together, and the rack 211 will drive the mounting frame 208 to move together, and the filter plate 210 that needs to be replaced is pulled out from the inside of the extruder 205, and the unused filter plate 210 is inserted into the inside of the extruder 205.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
