[0002] In plastic extrusion molding equipment, the plastic extruder is usually called the main machine, and the subsequent plastic extrusion molding machine supporting it is called the auxiliary machine. After more than 100 years of development, the plastic extruder has evolved from the original single screw to various models such as double screw, multi-screw, and even non-screw. The plastic extruder can be matched with various plastic molding auxiliary machines such as pipes, films, rods, monofilaments, flat filaments, packing tapes, wire meshes, plates, profiles, granulation, and cable coating to form various plastic extrusion molding production lines and produce various plastic products. Therefore, plastic extrusion molding machinery is one of the widely used machine types in the plastic processing industry, both now and in the future.

[0003] In the existing plastic extruder, during actual use, the raw materials to be processed are usually poured into the feeding hopper of the plastic extruder for feeding. This feeding method is likely to cause the feeding hopper to become blocked when a large amount of raw materials are loaded, thus affecting the production efficiency of the plastic extruder and making it inconvenient to use. Therefore, we propose a feeding anti-blocking mechanism for a plastic extruder to solve the above problems. Content of the Utility Model

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0025] Reference Figures 1-4 A feed anti-blocking mechanism for a plastic extruder, comprising:

[0026] Base 1;

[0027] The components include a hopper 2, a bracket 3, a motor 4, a threaded rod 5, a transmission plate 11, and striking blocks 12. The hopper 2 is fixedly connected to the top of the base 1 and passes through the base 1. The bracket 3 is fixedly connected to the top of the base 1. The motor 4 is fixedly connected to the top of the bracket 3. The output shaft of the motor 4 passes through the bracket 3. The threaded rod 5 is fixedly connected to the bottom of the output shaft of the motor 4. The transmission plate 11 is slidably connected to the bottom of the bracket 3. There are two striking blocks 12. The two striking blocks 12 are symmetrically fixedly connected to the left side of the transmission plate 11. The left sides of the two striking blocks 12 are in contact with the outer wall of the hopper 2.

[0028] The moving mechanism is connected to the transmission plate 11 and is used to drive the transmission plate 11 and the striking block 12 to move.

[0029] Through the above mechanism: the motor 4 can easily drive the threaded rod 5 to rotate and transport raw materials to prevent blockage; the moving mechanism can easily drive the transmission plate 11 to move; the movement of the transmission plate 11 can drive the striking block 12 to move back and forth; the striking block 12 can easily strike the feeding hopper 2 to generate vibration, preventing raw materials from adhering to or accumulating on the inner wall of the feeding hopper 2.

[0030] As a preferred embodiment of the present invention, the moving mechanism includes: a transmission wheel 6, a contact plate 7, and a sliding plate 8;

[0031] The transmission wheel 6 is fixedly connected to the outer wall of the output shaft of the motor 4, the slide plate 8 is slidably connected to the bottom inner wall of the bracket 3, and the contact plate 7 is fixedly connected to the rear side of the slide plate 8. The left side of the contact plate 7 is in movable contact with the outer wall of the transmission wheel 6, and the right side of the slide plate 8 is fixedly connected to the left side of the transmission plate 11. When the transmission wheel 6 rotates, it will contact the contact plate 7 and push the contact plate 7 to the right. When the contact plate 7 moves to the right, it will drive the slide plate 8 to move. At the same time, the right movement of the slide plate 8 will drive the transmission plate 11 to move to the right and compress the reset spring 13. At this time, the movement of the transmission plate 11 will cause the striking block 12 to disengage from the hopper 2.

[0032] As a preferred embodiment of this utility model, the bottom of the bracket 3 is fixedly connected to a limiting plate 9. The limiting plate 9 has a hollow structure, and the inner wall of the limiting plate 9 is slidably connected to the outer wall of the slide plate 8. The limiting plate 9 can conveniently restrict the slide plate 8, so that the slide plate 8 can move laterally stably.

[0033] As a preferred embodiment of this utility model, a limiting spring 10 is fixedly connected to the right side of the contact plate 7, and the right side of the limiting spring 10 is fixedly connected to the left side of the limiting plate 9. The elastic force of the limiting spring 10 facilitates the lateral movement and reset of the contact plate 7.

[0034] As a preferred embodiment of this utility model, two reset springs 13 are symmetrically fixedly connected to the left side of the bracket 3. The left side of each of the two reset springs 13 is fixedly connected to the right side of the transmission plate 11. The elastic force of the reset springs 13 facilitates the reset of the transmission plate 11, so that the striking block 12 contacts the hopper 2.

[0035] As a preferred embodiment of this utility model, a limiting frame 14 is fixedly connected to the left side of the bracket 3. The top of the limiting frame 14 is slidably connected to the bottom of the transmission plate 11, and the limiting frame 14 passes through the transmission plate 11. The limiting frame 14 facilitates normal limiting of the transmission plate 11, so that the transmission plate 11 can move laterally stably.

[0036] It should be noted that the specific model of motor 4 used is to be selected by those skilled in the art, and the motor 4 and other related technologies mentioned above are all existing technologies, which will not be elaborated upon in this solution.

[0037] The working principle of this utility model is as follows: In actual use, when it is needed, the base 1 is installed in a suitable position so that the hopper 2 is connected to the feed port of the plastic extruder. At this time, the raw material to be processed can be poured into the hopper 2. Then, the motor 4 is started. The motor 4 is powered by an external power supply. The rotation of the output shaft of the motor 4 drives the transmission wheel 6 to rotate and drives the threaded rod 5 to rotate. The rotation of the threaded rod 5 drives the raw material to move, preventing the raw material from accumulating and blocking. At the same time, when the transmission wheel 6 rotates, it will contact the contact plate 7 and push the contact plate 7 to the right. When the contact plate 7 moves to the right, it will drive the slide plate 8 to move. When the contact plate 7 moves, it will compress the limit spring 10. At the same time, the slide plate 8 moves to the right. The transmission plate 11 moves to the right, compressing the reset spring 13. At this time, the movement of the transmission plate 11 will cause the striking block 12 to disengage from the hopper 2. The limit frame 14 can support and limit the transmission plate 11, so that the transmission plate 11 can move laterally stably. When the transmission wheel 6 rotates and disengages from the contact plate 7, the limit spring 10 loses its restriction and pushes the contact plate 7 to move to the left to reset and drive the slide plate 8 to reset. At the same time, the reset spring 13 loses its restriction and pushes the transmission plate 11 to move laterally to reset. The lateral movement of the transmission plate 11 will cause the striking block 12 to move and contact the outer wall of the hopper 2, thereby causing the hopper 2 to vibrate. This facilitates material feeding, prevents raw materials from adhering or accumulating, and has good practicality.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
