[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figure 1 - Figure 2, An embodiment provided by the present utility model: An automatic feeding device for a mechatronic injection molding machine, including a feed bin 1, the top cover of the feed bin 1 can be removed, a feed inlet 3 is provided at the top end of the feed bin 1, and a feeding port 2 is provided at the bottom end of the feed bin 1. Raw materials are put into the feed bin 1 through the feed inlet 3 and then added to the equipment through the feeding port 2 for processing. A motor a4 is welded to the top end of the feed bin 1, a rotating shaft 5 is fixedly connected to the output shaft of the motor a4, and a ring 6 is fixedly connected to the bottom end of the rotating shaft 5. Driving the motor a4 can drive the rotating shaft 5 to rotate, thereby driving the ring 6 to rotate. A rectangular block 7 is fixedly connected to the inner wall of the feed bin 1, a guide rod 8 is slidably connected to the inner wall of the rectangular block 7, and a rubber ring is provided on the surface of the guide rod 8, which can prevent it from falling off the rectangular block 7 to a certain extent. However, if pulled forcefully, the guide rod 8 can still be taken out of the rectangular block 7. The top end of the guide rod 8 is fixedly connected to a sieve plate 9. Raw materials are put into the feed bin 1 through the feed inlet 3 and fall onto the sieve plate 9. An extrusion block 10 is fixedly connected to the outer wall of the ring 6, and the outer wall of the extrusion block 10 is in contact with the bottom end of the guide rod 8. The rotation of the ring 6 drives the extrusion block 10 to rotate. The two sides of the extrusion block 10 are set as inclined surfaces, while the bottom end of the guide rod 8 is provided with an arc surface. During the rotation of the extrusion block 10, it extrudes the bottom end of the guide rod 8 to slide along the inner wall of the rectangular block 7, thereby driving the sieve plate 9 to vibrate at a high frequency in the vertical direction to screen granular raw materials and screen out larger granular raw materials to prevent the situation of incomplete melting during subsequent heat melting. When the top cover is removed, the motor a4 and the sieve plate 9 can be taken off together, and the screened large particles can be taken out of the feed bin 1.
[0031] Refer to Figure 1 - Figure 3The side wall of the feeding port 2 is detachably connected with a shell 11, and a motor b12 is welded on the back of the shell 11. A central shaft 13 is fixedly connected to the output shaft of the motor b12. The driving motor b12 can drive the central shaft 13 to rotate. A plurality of groups of partition plates 14 are detachably connected to the outer wall of the central shaft 13. A plurality of groups of T-blocks 15 are fixedly connected to the surface of the central shaft 13. A plurality of groups of T-slots 16 are provided on the inner wall of the partition plate 14. The outer wall of the T-block 15 is snap-fitted with the inner wall of the T-slot 16. The T-block 15 is snap-fitted in the T-slot 16 to fix the partition plate 14 on the central shaft 13. Different numbers of partition plates 14 can be installed according to specific feeding requirements, so as to adjust the intervals between each partition plate 14. When the central shaft 13 rotates, the raw materials can be evenly dropped through the partition plates 14. While quantitative feeding is performed, the clogging problem is avoided. The inner wall of the central shaft 13 is detachably connected with a limiting plate 17, and the limiting plate 17 is used to resist the connection point between the T-block 15 and the T-slot 16 to prevent the partition plate 14 from falling off The inner wall of the limit plate 17 is elastically connected to the pressing rod 18 through the return spring 22. One end of the return spring 22 is fixedly connected to the inner end of the pressing rod 18, and the other end of the return spring 22 is fixedly connected to the inner wall of the limit plate 17. Pressing the pressing rod 18 inward can squeeze the return spring 22 to move inward. At the same time, the elastic force generated by the deformation of the return spring 22 gives the pressing rod 18 a reverse thrust to reset it. The outer wall of the pressing rod 18 is hinged with a bracket 19, and the end of the bracket 19 The end is hinged with a snap assembly, which includes a block 20. The inner side of the block 20 is hinged to the end of the bracket 19. The outer wall of the block 20 is slidably connected to the inner wall of the central axis 13. Pressing the pressing rod 18 inward can cause the angle of the bracket 19 to be offset, thereby dragging the block 20 to move inward and retract. A slot 21 is provided on the inner wall of the central axis 13. The outer wall of the block 20 is snapped with the inner wall of the slot 21. The block 20 is snapped into the slot 21 to fix the limit plate 17 on the central axis 13 to prevent the partition plate 14 from falling off.
[0032] Working principle: put the raw material into the silo 1 through the feed port 3, start the motor a4 to make the rotating shaft 5 drive the ring 6 to rotate, so that the extrusion block 10 fixed on the outer wall makes a circular motion, and the guide rod 8 slides repeatedly along the rectangular block 7, driving the screen plate 9 to vibrate, and the larger raw material particles are screened out to prevent the hot melting effect from being poor. After that, the top cover together with the screen plate 9 can be taken out to collect the large particles of raw material screened out, and then the raw material is put into the processing equipment through the feeding port 2. During this process, start the motor b12 to make the central axis 13 drive the partition plate 14 to make a circular motion, so that the raw material is evenly fed and the clogging problem of the feeding port 2 is avoided. When the feeding rate needs to be further adjusted, the outer shell 11 together with the central axis 13 can be removed, and the pressing rod 18 can be pressed inward to remove the limit plate 17, and the number of the partition plates 14 and the intervals between them can be adjusted to further control the amount and rate of feeding.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
