Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, specifically to an extrusion structure for producing plastic products. Background Technology

[0002] Plastic products are a general term for daily necessities and industrial products made primarily from plastics. They are a class of plastic synthetic polymer materials that are obtained through chemical reactions such as polymerization or polycondensation with synthetic monomers in synthetic resins. During the manufacturing process, they can be molded into plastic semi-finished products or finished products of a certain shape and maintain their shape under certain conditions. Plastic products are lightweight, have good insulation, and are highly corrosion resistant, and therefore have been widely used in many fields.

[0003] The extrusion structure commonly used in the production of plastic products is the extrusion die head, also known as a mold. During the extrusion process, plastic granules or powder are added into the barrel of the extruder and heated and plasticized under the action of the rotating screw. The plasticized plastic melt enters the extrusion die head through the extrusion action of the screw. Inside the die head, the melt goes through stages such as diversion, compression, stable flow and shaping, and is finally extruded through the die to become a plastic product with a certain cross-sectional shape.

[0004] Existing extrusion structures used for producing plastic products cannot properly mix the plastic material or prevent clogging. This necessitates that workers mix the plastic with different additives before feeding it into the hopper. Excessive plastic material can easily accumulate at the bottom of the hopper, causing blockages, affecting normal production, and reducing efficiency. Furthermore, the extrusion structure requires heating and melting the plastic during extrusion, making the plastic in the hopper susceptible to melting due to the heating effect, thus impacting the extrusion efficiency. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an extrusion structure for producing plastic products, comprising...

[0006] An extrusion cylinder has a feed pipe fixedly installed on one side of the upper end of the extrusion cylinder, and a feed hopper is fixedly installed at the upper end of the feed pipe.

[0007] A rotating shaft is installed through the center of the feed hopper, and several support rods are fixedly installed at equal intervals on the center of the outer side wall of the rotating shaft.

[0008] A stirring shaft is rotatably installed at the center of both the upper and lower ends of the support rod. Stirring rods are fixedly installed at equal intervals on the outer side wall of the stirring shaft. A telescopic column is fixedly installed at one end of the support rod.

[0009] One side of the telescopic column is equipped with a shaped scraper that fits tightly against the inner wall of the feed hopper.

[0010] Preferably, rolling bearings are fixedly installed at both the upper and lower ends of the support rod, and a stirring shaft is rotatably installed on the inner side of each rolling bearing. A telescopic spring is installed between the telescopic column and the irregular scraper.

[0011] Preferably, the upper end of each feed hopper is fixedly equipped with a support block in a cross pattern, the upper end of the support block is fixedly equipped with a rotary motor, and the output end of the rotary motor is connected to and installed with a rotating shaft.

[0012] Preferably, a barrier box is fixedly installed at the upper end of the feed pipe near the lower end of the feed hopper. A barrier shaft is rotatably installed through the center of the barrier box. A rotating motor is fixedly installed at the center of one side of the barrier box. The output end of the rotating motor is connected to the barrier shaft. Barrier baffles are symmetrically fixedly installed on the outer walls of the barrier shaft in pairs.

[0013] Preferably, the inner sidewall of the barrier box is provided with two symmetrical rotating grooves on the side near the barrier baffle, and a magnetic groove is provided on the inner side of the rotating groove near the bottom center. A magnetic block that fits into the magnetic groove is fixedly installed at one end of the barrier baffle near the port.

[0014] Preferably, a conical extrusion cylinder is detachably installed at one end of the extrusion cylinder, an extrusion screw is rotatably installed on the inner side of the extrusion cylinder, and a drive motor is fixedly installed on the side of the extrusion cylinder away from the conical extrusion cylinder, with the output end of the drive motor connected to the extrusion screw.

[0015] Compared with the prior art, this utility model provides an extrusion structure for producing plastic products, which has the following advantages:

[0016] 1. By setting up four pairs of two sets of symmetrically rotating and adjustable stirring shafts and irregular scrapers, the plastic particles containing different additives can be mixed after the workers put the plastic products to be extruded into the feed hopper. This avoids the problem of too much plastic material being put into the feed hopper and easily accumulating at the bottom of the feed hopper, causing blockage, and further improving production efficiency.

[0017] 2. By setting up a barrier box and barrier baffles, when the extrusion cylinder heats the plastic entering through the feed hopper, the barrier shaft can be rotated in time to block the hot air, thus preventing the plastic in the feed hopper from being easily affected by the heating of the extrusion structure, causing the plastic in the feed hopper to melt easily and thus affecting the extrusion efficiency of the extrusion structure.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example 1

[0027] Reference Figure 1-4This is the first embodiment of the present invention, which provides an extrusion structure for producing plastic products, including an extrusion cylinder 1. A feed pipe 2 is fixedly installed on one side of the upper end of the extrusion cylinder 1. A feed hopper 3 is fixedly installed on the upper end of the feed pipe 2. A rotating shaft 5 is rotatably installed through the center of the feed hopper 3. Several support rods 6 are fixedly installed at equal intervals on the center of the outer side wall of the rotating shaft 5. A stirring shaft 7 is rotatably installed at the center of both the upper and lower ends of the support rods 6. A stirring rod 8 is fixedly installed at equal intervals on the outer side wall of the stirring shaft 7. A telescopic column 9 is fixedly installed at one end of each support rod 6. A shaped scraper 10 that is closely attached to the inner wall of the feed hopper 3 is movably installed on one side of each telescopic column 9.

[0028] Rolling bearings are fixedly installed at both the upper and lower ends of the support rod 6. A stirring shaft 7 is rotatably installed on the inner side of the rolling bearings. A telescopic spring is installed between the telescopic column 9 and the irregular scraper 10. Support blocks 4 are fixedly installed in a cross pattern at the upper end of the feed hopper 3. A rotary motor 11 is fixedly installed at the upper end of the support block 4. A rotating shaft 5 is connected to the output end of the rotary motor 11. A conical extrusion cylinder 17 is detachably installed at one end of the extrusion cylinder 1. An extrusion screw 18 is rotatably installed on the inner side of the extrusion cylinder 1. A drive motor 19 is fixedly installed on the side of the extrusion cylinder 1 away from the conical extrusion cylinder 17. The extrusion screw 18 is connected to the output end of the drive motor 19.

[0029] When the extrusion structure used in the production of plastic products is in use, the operator first puts the plastic to be extruded and the additives into the inner side of the feed hopper 3 in proportion, and then starts the rotary motor 11. Under the drive of the rotary motor 11, the rotating shaft 5 rotates, thereby driving the four sets of support rods 6 fixedly installed at the center of the rotating shaft 5. The stirring shaft 7 at the upper end of the rolling bearing is driven by the rotation of the rotating shaft 5, and the stirring rod 8 is forced to rotate. This can quickly and timely mix the plastic products and additives inside the feed hopper 3, and at the same time avoid the plastic material being put into the feed hopper 3 too much, which can easily accumulate at the bottom of the feed hopper 3 and cause blockage, thus further improving production efficiency.

[0030] The mixed plastic product reaches the extrusion cylinder 1 through the feed pipe 2. At the same time, the drive motor is started, causing the extrusion screw 18 to rotate under the drive of the drive motor 19. While the extrusion screw 18 is rotating, the heating component on the inner wall of the extrusion cylinder 1 is activated, so that the plasticized plastic melt enters the conical extrusion cylinder 17 through the extrusion action of the screw. In the conical extrusion cylinder 17, through the components set inside, the melt goes through stages such as diversion, compression, stable flow and shaping, and finally is extruded through the extrusion head set at one end of the conical extrusion cylinder 17 to become a plastic product with a certain cross-sectional shape.

[0031] Example 2

[0032] Reference Figure 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a barrier box 12 is fixedly installed at the upper end of the feed pipe 2 near the lower end of the feed hopper 3; a barrier shaft 13 is rotatably installed through the center of the barrier box 12; a rotating motor 20 is fixedly installed at the center of one side of the barrier box 12; the output end of the rotating motor 20 is connected to the barrier shaft 13; barrier baffles 14 are symmetrically fixedly installed on the outer side wall of the barrier shaft 13; rotating grooves 15 are symmetrically opened on the inner side wall of the barrier box 12 near the side of the barrier baffles 14; magnetic grooves 16 are opened on the inner side of the rotating grooves 15 near the center of the bottom end; and a magnetic block that fits into the magnetic groove 16 is fixedly installed at one end of the barrier baffles 14 near the port.

[0033] When the extrusion structure for producing plastic products is used, the mixed plastic products reach the extrusion cylinder 1 through the feed pipe 2. Simultaneously, the rotating motor 20 is started, causing the blocking shaft 13 to rotate under the drive of the rotating motor 20. As a result, the blocking baffle 14 rotates within the space of the rotating groove 15 under the action of the blocking shaft 13. Consequently, the magnetic block set at one end of the blocking baffle 14 and the magnetic groove 16 are completely attached under the action of the magnetic field. This allows the extrusion cylinder 1 to promptly block the hot air when heating the plastic entering through the feed hopper 3, preventing the plastic in the feed hopper 3 from being easily affected by the heating of the extrusion structure, which would cause the plastic in the feed hopper 3 to melt due to heat, thereby affecting the extrusion efficiency of the extrusion structure.

[0034] The remaining structure is the same as that in Example 1.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
