Description

Technical Field

[0001] The utility model relates to the field of extrusion machines, and more specifically, to an extrusion machine for plastic processing that can prevent pollution. Background Art

[0002] An extrusion machine is one of the commonly used production equipment in the field of plastic processing. Its working principle is to heat plastic raw materials to a certain temperature, and then extrude the raw materials from the heating cylinder through a pressure device such as a screw or a plunger, and then form the required product shape through a mold.

[0003] However, there are some problems in the actual working process of the existing extrusion machines for plastic processing. For example, a fast extrusion machine with the publication number CN215703909U can heat the plastic raw materials piled on the bearing plate during the working process. However, during the piling process of the plastic raw materials, only one stirring blade at the bottom rotates, and it is not possible to stir and heat the piled plastic raw materials in all directions. Therefore, the piled plastic raw materials cannot be preheated evenly. Moreover, during the heating process of the plastic raw materials, toxic waste gases are easily generated. In the actual working process of the existing extrusion machines, the toxic waste gases generated during preheating cannot be purified, which is likely to cause environmental pollution. Therefore, we have made improvements and proposed an extrusion machine for plastic processing that can prevent pollution. Summary of the Utility Model

[0041] like Figures 1-4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a slot 9 is provided at the side end of the activated carbon mesh plate 8, a return spring 10 is welded and fixed to the top side end of the feeding barrel 6, and a clamping rod 11 is welded and fixed to the other end of the return spring 10, the clamping rod 11 is limited and slidably connected in the feeding barrel 6, and the end of the feeding barrel 6 is clamped and connected in the slot 9, and the positioning grooves 7 are symmetrically distributed on both sides of the top of the feeding barrel 6, the positioning grooves 7 correspond to the activated carbon mesh plate 8 one by one, and the side end surface of the activated carbon mesh plate 8 is in contact with the inner wall of the positioning groove 7, and the slot 9 is provided in the middle part of the side end of the activated carbon mesh plate 8, and the cooperation of the slot 9 and the clamping rod 11 can conveniently and stably complete the disassembly and installation of the activated carbon mesh plate 8, thereby ensuring the convenience of the subsequent feeding of the plastic raw materials, and at the same time ensuring that the activated carbon mesh plate 8 can be conveniently and stably replaced after working for a long time, thereby ensuring the stability of the activated carbon mesh plate 8 in the long-term working state.

[0042] like Figure 3 , Figure 5 and Figure 6 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the vertical center line of the electric heating tube 18 and the vertical center line of the feeding barrel 6 are located on the same vertical line, the limit rods 19 are symmetrically distributed on the left and right sides of the electric heating tube 18, the connecting springs 20 are symmetrically distributed on the upper and lower sides of the electric heating tube 18, the connecting springs 20 correspond to the connecting sleeves 21 one by one, the cross-section of the guide block 23 is semicircular, the guide blocks 23 are symmetrically distributed on both sides of the connecting sleeve 21, the connecting sleeve 21 and the stirring rod 22 are both made of heat-conducting material, the electric heating tube 18 drives the connecting sleeves 21 on the upper and lower sides to rotate synchronously through the limit rod 19, thereby driving the stirring rod 22 to rotate stably, at this time, under the guiding and pushing action of the guide block 23, the connecting spring 20 can push the connecting sleeve 21 in the rotation process to perform automatic and stable up and down reciprocating motion, combined with each stirring rod 22, the plastic raw materials in the feeding barrel 6 can be stirred in all directions, and under the action of heat conduction, the uniform preheating treatment of the plastic raw materials in various places inside the feeding barrel 6 can be completed conveniently and stably.

[0043] like Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the cutting blades 25 are evenly distributed on both sides of the rotating rod 24, and the length of the cutting blades 25 gradually decreases from top to bottom. The bottom of the feeding barrel 6 is funnel-shaped. Under the continuous rotation of each cutting blade 25, the plastic raw materials in the feeding process can be stirred and cut to avoid agglomeration of the plastic raw materials after preheating and causing blockage.

[0044] Specifically, when the pollution-proof plastic processing extruder is in use: First, the staff can pull the clamping rod 11 on the feeding cylinder 6 outwards until the clamping rod 11 moves out of the clamping slot 9 on the activated carbon mesh plate 8. Then, the staff can lift the activated carbon mesh plate 8. At this time, the staff can convey the plastic raw materials into the feeding cylinder 6. Under the action of the two side baffles 14, the feeding cylinder 6 can be divided into two areas. The area above the baffle 14 is the preheating area, and the area below the baffle 14 is the feeding area. After the plastic raw materials are conveyed into the feeding cylinder 6, under the bearing action of the baffle 14, they can stably fall into the preheating area above the baffle 14. Then, the staff can pull the clamping rod 11 on the feeding cylinder 6 outwards again. At the same time, place the activated carbon mesh plate 8 in the positioning slot 7. Then, the staff can release the clamping rod 11. At this time, under the elastic action of the return spring 10, it can drive the clamping rod 11 to rotate and engage into the clamping slot 9 on the side end of the activated carbon mesh plate 8, completing the clamping and fixing of the activated carbon mesh plate 8. The activated carbon mesh plate 8 can be used to purify the toxic waste gas generated by heating the plastic raw materials, avoiding the pollution of the environment caused by the toxic waste gas generated by heating the plastic raw materials. And by the cooperation of the clamping slot 9 and the clamping rod 11, the disassembly and installation of the activated carbon mesh plate 8 can be completed conveniently and stably. Furthermore, it can ensure the convenience of the subsequent feeding work of the plastic raw materials. At the same time, it can ensure that after the activated carbon mesh plate 8 works for a long time, it can be replaced conveniently and stably, ensuring the stability of the long-term working state of the activated carbon mesh plate 8;

[0045] Then the staff can drive the servo motor 17. Under the driving action of the servo motor 17, the electric heating tube 18 can be driven through the output shaft. At this time, under the rotation of the electric heating tube 18, the limit rods 19 on the left and right sides can drive the connecting sleeves 21 on the upper and lower sides to rotate synchronously. Under the rotation of the connecting sleeve 21, the stirring rod 22 can be driven to perform automatic stirring. At this time, during the rotation of the stirring rod 22, it can intermittently contact the guide blocks 23 on both sides. Under the guiding action of the arc surface of the guide block 23, the stirring rod 22 in the rotation process can push the upper connecting sleeve 21 to move downward automatically. Similarly, during the rotation of the lower connecting sleeve 21, the stirring rod 22 and the guide block at the lower side end can be driven. 23, and the stirring rod 22 in the process of rotating under the guiding and pushing action of the guide block 23 can push the connecting sleeve 21 below to automatically move upward, and when the stirring rod 22 moves away from the guide block 23, under the elastic action of the connecting spring 20, it can drive the connecting sleeve 21 to move and reset, and so on. The connecting sleeves 21 on the upper and lower sides can automatically and stably reciprocate up and down during the rotation process, and the combination of each stirring rod 22 can stir the plastic raw materials at various places inside the feeding barrel 6 in all directions. Under the heating action of the electric heater 3, combined with the heat conduction of the connecting sleeve 21 and each stirring rod 22, the uniform preheating treatment of the plastic raw materials at various places inside the feeding barrel 6 can be completed conveniently and stably, effectively improving the uniformity of the preheating of the plastic raw materials;

[0046] After the preheating of the plastic raw materials is completed, the staff can pull the magnetic plate 15 outwards. At this time, the magnetic plate 15 moves away from the feeding tube 6, and by continuing to pull the magnetic plates 15 on both sides, the baffles 14 on both sides can be driven to move outwards, and ensure that the baffles 14 will not completely separate from the feeding tube 6 to avoid leakage problems. At this time, under the action of the movement and opening of the baffles 14 on both sides, the preheated plastic raw materials can automatically fall to the feeding area below, and then the staff can push the baffles 14 on both sides to move to the middle and reset to complete the closing. At this time, the magnetic plate 15 can be magnetically adsorbed on the feeding tube 6 to ensure the stability of the closed state of the baffle 14, and then the next batch of plastic raw materials are transported and preheated. At this time, the preheating of the next batch of plastic raw materials and the feeding of this batch of plastic raw materials are carried out simultaneously. At this time, under the driving action of the servo motor 17, the electric heating tube 18 can drive the rotating rod 24 to rotate stably, and combined with each cutting blade 25, the plastic raw materials in the feeding process can be stirred and cut to avoid agglomeration of the plastic raw materials after preheating and cause blockage;

[0047] Subsequently, the plastic raw material can be stably conveyed into the barrel 2. Under the driving action of the driving motor 4, the screw rod 5 can rotate stably. Cooperating with the barrel 2, the plastic raw material can be fed at a constant speed, and the plastic raw material can be evenly plasticized through the electric heater 3. Subsequently, the plastic can be conveyed to molds of different shapes through the head at the end of the barrel 2, so that the plastic is extruded into various shaped products, completing the extrusion work.

Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific embodiments.
