[0040] See also Figure 1 and Figure 3 The crushing structure 20 includes a mounting plate 210, a first servo motor 220, a rotating shaft 230, a crushing blade head 240 and a screw 250. The mounting plate 210 is arranged in the loading box 130. The first servo motor 220 is installed on one side of the mounting plate 210.

[0042] The working principle of the feeding device of the injection molding machine is as follows: when the feeding device of the injection molding machine is used, the raw material is placed in the feeding box 130. At this time, the first electric push rod 121 is turned on to drive the support plate 122 to move, so that the feeding box 130 is raised. After reaching a suitable height, the second servo motor 112 drives the ball screw pair 113 to rotate, so that the screw nut pair 114 drives the feeding box 130 to move, so that the bottom of the feeding box 130 corresponds to the feeding port of the injection molding machine, which is convenient for moving and lifting the feeding box 130, thereby facilitating feeding and reducing labor intensity. During the process of moving and lifting the loading box 130, the first servo motor 220 drives the rotating shaft 230 and the crushing blade head 240 to rotate, which is convenient for crushing the raw materials during the process of moving and lifting, thereby improving work efficiency. At the same time, the rotating shaft 230 drives the scraper frame 260 to rotate, which can facilitate timely cleaning of the inner wall of the loading box 130, thereby improving work efficiency. By turning on the second electric push rod 151 to drive the slide plate 152 to move, the discharge of raw materials is facilitated. At the same time, by reversing the first servo motor 220, the screw 250 rotates to avoid blockage during material discharge.

[0043] It should be noted that the specific models and specifications of the second servo motor 112, the first electric push rod 121, the second electric push rod 151 and the first servo motor 220 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
