[0003] Plastic products are generally produced and formed by using a material extrusion device. Through processes such as heating, plasticizing, and mixing, and then extruded through a specific extrusion die orifice into plastic products of a certain shape.
[0004] The specific working principle is as follows: Granular plastic raw materials are put into a feeding hopper, enter an extrusion box, and then through a feeding screw preset in the extrusion box, while being heated and melted and conveyed forward to the extrusion die orifice, and then come out through the extrusion die orifice to be formed, and finally cooled and shaped into plastic products.

Specific embodiments
[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0028] Referring to Figures 1-5 , an extrusion device for plastic product production, including an equipment frame 1, on which a material extrusion box 11 and a driving motor 2 are arranged. The driving motor 2 is provided with a motor shaft 21. The material extrusion box 11 is provided with a feeding hopper 12 and a material extrusion die orifice 13. A screw connecting shaft 23 is arranged in the material extrusion box 11. A coupling 22 is arranged between the motor shaft 21 and the screw connecting shaft 23. An upper stabilizing ring group 4 and a lower stabilizing ring group 5 are arranged on the equipment frame 1;
[0029] A cylinder seat 3 is arranged on the equipment frame 1. A pressing cylinder 31 is arranged on the cylinder seat 3. A pressing plate 32 is arranged on the pressing cylinder 31. A pressing rod 33 is arranged on the pressing plate 32. Both the upper stabilizing ring group 4 and the lower stabilizing ring group 5 are composed of a stabilizing seat 6 and a rolling bead 7. An opening groove 61 and an oil cavity 62 are opened on the stabilizing seat 6. A communication hole 63 and a bead groove 64 are opened on the stabilizing seat 6;
[0030] The stable seat 6 is provided with an oil replenishing hole 65, and a plug column 8 is arranged in the oil replenishing hole 65. A pull ring 81 and a sealing head 82 are arranged on the plug column 8. Some structures described in this patent are common structures of the plastic extrusion device for plastic product production, which are prior arts. Some prior structures are not drawn and marked, so they will not be elaborated.
[0031] The cylinder seat 3 and the pressing cylinder 31 are a group, and there are two groups symmetrically arranged in total. The pressing plate 32 is in a cross-shaped structure as a whole. The symmetric pressing cylinders 31 enable the upper stabilizing ring group 4 to move stably downward and stably press the motor shaft 21 through the rolling beads 7.
[0032] The rolling beads 7 are rotationally clamped in the bead grooves 64. The rolling beads 7 and the bead grooves 64 are a group, and there are seven groups in total. The rolling beads 7 are made of hard alloy steel, which is oil-resistant, durable, and has high strength without deformation.
[0033] The stable seat 6 is in a cuboid structure as a whole. The opening groove 61 is a semi-circular inner groove as a whole and transversely penetrates the stable seat 6, realizing the stable positioning and clamping of the motor shaft 21.
[0034] The side cross-section of the oil cavity 62 is an arc-shaped inner cavity, realizing the uniform inflow of lubricating oil into each bead groove 64.
[0035] The communication holes 63 are respectively communicated with the oil cavity 62 and the bead grooves 64. When the rolling beads 7 are driven to roll, the lubricating oil in the bead grooves 64 can be evenly coated on the motor shaft 21 and the surface of the rolling beads 7 themselves.
[0036] The oil replenishing hole 65 is communicated with the oil cavity 62, and the plug column 8 is extruded and inserted into the oil replenishing hole 65, realizing the convenient replenishment of lubricating oil in the later stage.
[0037] The pull ring 81 is arranged at one end of the plug column 8 exposed from the oil replenishing hole 65, which is convenient for hooking with fingers and pulling out the plug column 8.
[0038] The sealing head 82 is extruded and arranged in the communication hole 63 and does not expose the oil cavity 62. Both the sealing head 82 and the plug column 8 are made of oil-resistant high-elastic rubber material. After being extruded into the oil replenishing hole 65, sealing is realized to avoid oil leakage.
[0039] Working mode: Start the driving motor 2, drive the screw connecting shaft 23 to rotate through the coupling 22, and then drive the preset feeding screw in the feeding box 11 to rotate. Then, a certain amount of plastic raw material particles are put into the feeding hopper 12 to realize the heating, feeding, and propulsion of the plastic raw material particles and the subsequent forming of plastic products through the extrusion die orifice 13 (which is a prior art);
[0040] Next, start the pressing cylinder 31. Drive the upper steady ring group 4 to move downward as a whole through the pressing plate 32 and the pressing rod 33. When the rolling beads 7 on the upper steady ring group 4 contact the outer wall of the motor shaft 21, stop the pressing cylinder 31. At this time, the outer wall surface of the motor shaft 21 is driven to roll, so as to symmetrically and stably press the parts of the motor shaft 21 at both ends of the coupling 22 up and down, avoiding the axial instability during the rotational transmission between the relatively long motor shaft 21 and the screw connecting shaft 23. Furthermore, the synchronous transmission performance of the motor shaft 21 through the coupling 22 is improved, ensuring the normal feeding and propulsion of the plastic raw materials for plastic products.
[0041] Moreover, when the motor shaft 21 rotates, it will drive the rolling beads 7 to rotate. The rolling beads 7 will take out the lubricating oil in the oil cavity 62 and evenly coat it on the rolling beads 7 and the motor shaft 21, realizing effective lubrication of the rolling beads 7 and improving the rotational smoothness of the rolling beads 7 in the bead grooves 64.
[0042] In addition, pulling the pull ring 81 can pull out the plug column 8. Then, replenish the lubricating oil in the oil cavity 62 through the oil replenishing hole 65. After replenishment, squeeze and insert the plug column 8 into the oil replenishing hole 65, which is convenient for replenishing the lubricating oil in the oil cavity 62.
[0043] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
