DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-5The utility model provides a technical solution: an automatic feeding adjustment device for an extruder, comprising a material box 1, a feeding barrel 2, a reduction motor 3, a movable shaft 4, a fixing rod 5, a scraper 6, an adjustment mechanism 7, an adjustment plate 8, a convex block 9, a feeding port 10, a connecting column 11, a fixing column 12, a fixing groove 13, a connecting rod 14 and a positioning block 15.

[0030] When using the extruder automatic feed adjustment device, if Figure 1 and Figure 2 As shown, the lower end of the material box 1 is fixedly connected with a feed barrel 2, and the material box 1 is connected to an external extrusion device. First, the raw material for producing high-fluidity and easy-to-inject ABS plastic is added to the material box 1, and then the reduction motor 3 installed on the upper end of the material box 1 is started. The output end of the reduction motor 3 is fixedly connected with a movable shaft 4. The reduction motor 3 drives the movable shaft 4 to rotate in the material box 1, and the fixed rod 5 is fixedly connected to the side of the movable shaft 4. The scraper 6 is fixedly connected to the fixed rod 5. Through the setting of the fixed rod 5 and the scraper 6, the material inside the material box 1 can be disturbed to prevent the material from being blocked during feeding. In addition, the scraper 6 is fitted on the inner wall of the material box 1. Through the setting of the scraper 6, the material is prevented from adhering to the material box 1 and residue is avoided.

[0031] Combination Figure 3 , Figure 4 and Figure 5 As shown, an adjusting mechanism 7 is provided at the lower end of the feed barrel 2, and the adjusting mechanism 7 includes an adjusting plate 8 fittedly arranged at the lower end of the feed barrel 2, a convex block 9 in a "T"-shaped structure, and a feed port 10 opened at the lower left end of the adjusting plate 8. By rotating the connecting rod 14, the connecting rod 14 rotates at the upper end of the connecting column 11, and the torsion spring at the connection between the connecting rod 14 and the connecting column 11 undergoes elastic deformation, and the connecting rod 14 drives the positioning block 15 to rotate, so that the positioning block 15 is pulled out of the fixing groove 13, thereby loosening the limit between the fixing column 12 and the connecting column 11, and then the adjusting plate 8 is pushed to the left, and the adjusting plate 8 slides between the convex block 9, and the adjusting plate 8 drives the connecting column 11 to slide between the fixing column 12, so that the feed port 10 slowly overlaps with the lower end of the feed barrel 2. At this time, the raw materials inside the material box 1 enter the extruder through the feed barrel 2 and the feed port 10 for extrusion processing;

[0032] Moreover, the size of the overlapping opening between the feed port 10 and the feed barrel 2 can be adjusted by controlling the moving distance of the adjustment plate 8, thereby adjusting the feed rate of the material. When it is adjusted to a suitable position, the connecting rod 14 is directly loosened. At this time, the torsion spring restores its elastic deformation, driving the connecting rod 14 to rotate at the upper end of the connecting column 11. The fixed grooves 13 are arranged at equal intervals on the fixed column 12, so that the connecting rod 14 drives the positioning block 15 to engage in the fixed groove 13 at the corresponding position, thereby facilitating the fixing of the adjustment plate 8 at the corresponding position at the lower end of the feed barrel 2.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
