DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "setting" should be understood in a broad sense, for example, it can be fixed connection, setting, or detachable connection, setting, or integral connection, setting.

[0030] When the prior art is in use, the heat dissipating fan dissipates heat for the extruder, and the hot air is transported to the feed hopper through the connecting pipe. At the same time, the hot air is blown toward the raw materials in the feed hopper through the rotating tube and the exhaust hole, thereby preheating the raw materials and increasing the initial temperature of the raw materials.

[0044] like Figure 3 and Figure 6 As shown, the reciprocating assembly includes: a compression spring 703, a damper 704; One end of the compression spring 703 and the damper 704 are respectively fixedly connected to the movable plate 702, and the other end are respectively fixedly connected to the mounting plate 4; The damper 704 is disposed in the inner ring of the compression spring 703 to prevent the compression spring 703 from simple harmonic motion.

[0045] Specifically, by providing the damper 704, the reciprocating rebound caused by the release of the compressed spring 703 after storing energy is avoided, thereby ensuring the stability of the entire reciprocating motion.

[0046] like Figure 2 As shown, the extruder 5 is connected to the reduction box 2.

[0047] like Figure 4 As shown, a feed port 609 is provided at the bottom of the feed hopper 9 , and the feed port 609 is connected to the extruder 5 .

[0048] like Figure 7 As shown, the mounting plate 4 is connected with a crushing mechanism 8, which includes: a support column 801, a crushing box 802, a support plate 803, and a second motor 804. There are four support columns 801, which are symmetrically arranged on the mounting plate 4.

Specifically, by setting the crushing mechanism 8, the purpose is to control the particle size of the raw material within 20 mm.

[0049] It is worth noting that, in order to facilitate control, the first motor, the second motor, the cooling fan and the heating component in this embodiment are respectively provided with control switches, and the control switches of the first motor, the second motor, the cooling fan and the heating component can respectively control the first motor, the second motor, the cooling fan and the heating component to work respectively.

[0050] The working principle of the present invention is as follows: by turning on the cooling fan to dissipate heat for the extruder 5, and then controlling the first motor inside the first chassis 3 placed on the platform to start, the operation of the first motor drives the third rotating shaft 1002 to rotate, and then drives the fan blades 1003 to rotate, while the third rotating shaft 1002 rotates, it drives the first pulley 601 to rotate, the first pulley 601 rotates through the belt 602 to drive the second pulley 603 to rotate, and drives the second pulley 603 to rotate and drive the first rotating shaft 604 to rotate, the first rotating shaft 604 rotates and is also connected to the T-shaped mounting plate 4 through the bearing rotation, and drives the first bevel gear 605 to rotate, the first bevel gear 605 rotates to drive the second bevel gear 605 to rotate, the second bevel gear 605 rotates to drive the second rotating shaft 607 to rotate, the second rotating shaft 607 rotates to drive the nine internal stirring rods 608 to rotate, so as to turn the internal raw materials to prevent blockage. , and the scraper is composed of two symmetrically arranged triangles. No matter what direction it turns, it scrapes the raw materials on the inner wall of the feed hopper 9 to prevent sticking. At the same time, it can also control the start of the heating component to heat the stirring rod 608. At the same time, the crushing box 802 crushes the raw materials. The crushed raw materials flow into the feed pipe 706 along the lowest point. The rotation of the first rotating shaft 604 drives the elliptical wheel 701 to rotate. The rotation of the elliptical wheel 701 will intermittently squeeze the T-shaped movable plate 702 to move downward, and make the compression spring 703 and the damper 704 compress the energy storage, and the knocking ball 705 knocks the feed pipe 706. After losing the force of the elliptical wheel 701 rotating to squeeze the T-shaped movable plate 702 to move downward, it will rise under the release of the energy storage of the compression spring 703 and the damping control of the damper. Under reciprocating, the knocking ball 705 repeatedly knocks the feed pipe 706 to prevent blockage during feeding.
