Description

Technical Field

[0001] This utility model relates to the technical field of anti-blocking feeding structure, specifically to an anti-blocking feed hopper for a plastic granulator. Background Technology

[0002] Plastic granulators are used to produce plastic into granules, and they are an important part of the plastics industry. Because plastic granules can be better used in the production of various plastic products, the market demand for plastic granules is very high, which has led to the emergence of different granulators.

[0003] Regardless of the type of granulator, plastic is extruded and then granulated. The raw material is fed into the extruder through the hopper. If too much raw material is put in at once, it is easy to cause hopper blockage. Once blocked, it can only be stopped and manually cleared, which is time-consuming, labor-intensive and affects the processing progress. Therefore, this paper proposes a plastic granulator with anti-blockage hopper. Utility Model Content

[0004] The technical problem this invention aims to solve is that feeding too much raw material at once can easily cause hopper blockage. Once blocked, manual unblocking is necessary, which is time-consuming, labor-intensive, and affects the processing progress. This invention provides an anti-blockage hopper for a plastic granulator, enabling automatic unblocking and avoiding downtime for unblocking that could affect the processing progress.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a plastic granulator anti-clogging feed hopper, including a hopper, a discharge pipe fixedly connected to the bottom end of the hopper, a telescopic rod detachably connected to one side outer ring wall of the discharge pipe, a motor detachably connected to the side wall of the discharge pipe away from the telescopic rod, a horizontal connecting plate provided inside the discharge pipe, two pairs of horizontal connecting plates provided, the two pairs of horizontal connecting plates having a rhomboid structure, and an anti-slip pad fixedly connected to the outer wall of the horizontal connecting plate.

[0006] As a preferred embodiment of this utility model, a connecting shaft is rotatably connected to one end of the transverse connecting plate, a conical plate is fixedly connected to one side wall of the connecting shaft, and an extension plate is rotatably connected to the outer side wall of the transverse connecting plate near the connecting shaft via a torsion spring, with one side wall of the extension plate fitting against the outer side wall of the transverse connecting plate.

[0007] As a preferred technical solution of this utility model, the output end of the telescopic rod extending into the discharge pipe is detachably connected to an extrusion shaft. A rotating groove is opened on the side wall of the end of the extrusion shaft away from the telescopic rod. A rotating ring is rotatably connected in the rotating groove. A rotating shaft is fixedly connected to one end of the rotating ring. One end of the rotating shaft is rotatably connected to one end of the corresponding two horizontal connecting plates.

[0008] As a preferred embodiment of this utility model, the output end of the motor extends into the discharge pipe and is detachably connected to a drive shaft. One end of the drive shaft and near both sides are rotatably connected to one end of the corresponding transverse connecting plate.

[0009] As a preferred embodiment of this utility model, an outer cover box is detachably connected to one side wall of the hopper, and a vibration motor is detachably connected to one side wall inside the outer cover box, with one end of the vibration motor fitting against the outer wall of the hopper.

[0010] This utility model has the following advantages: the activation of the telescopic rod can push the extrusion shaft close to the drive shaft. During this process, the two pairs of horizontal connecting plates will be extruded. Under the action of extrusion, the horizontal connecting plates, which were originally horizontal, gradually become vertical diamond structures. In this way, the upper horizontal connecting plate can be inserted into the blockage material. The horizontal connecting plates reciprocate to contract and extend under the drive of the extrusion shaft, thereby moving the material and causing the blockage material to move. With the space to move, the material will fall downward under the action of gravity, thereby achieving the effect of clearing the blockage.

[0011] The starting motor drives the cross plate to rotate, which in turn moves the material and pulls out the blocked material from the discharge pipe, thereby improving the cleaning effect. The extension plate increases the range of the equipment and improves the cleaning effect, while the conical plate improves the smoothness of the cross plate inserting into the material.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3This utility model discloses an anti-clogging feed hopper for a plastic granulator, comprising a hopper 1, a discharge pipe 2 fixedly connected to the bottom end of the hopper 1, a telescopic rod 3 detachably connected to one side outer wall of the discharge pipe 2, a motor 4 detachably connected to the side wall of the discharge pipe 2 away from the telescopic rod 3, a horizontal connecting plate 10 provided inside the discharge pipe 2, two pairs of horizontal connecting plates 10 provided, the two pairs of horizontal connecting plates 10 having a rhomboid structure, and an anti-slip pad fixedly connected to the outer wall of the horizontal connecting plate 10;

[0018] A connecting shaft 11 is rotatably connected to one end of the horizontal connecting plate 10. A conical plate 13 is fixedly connected to one side wall of the connecting shaft 11. An extension plate 12 is rotatably connected to the outer side wall of the horizontal connecting plate 10 near the connecting shaft 11 via a torsion spring. One side wall of the extension plate 12 fits against the outer side wall of the horizontal connecting plate 10. The output end of the telescopic rod 3 extending into the discharge pipe 2 is detachably connected to an extrusion shaft 7. A rotating groove 14 is opened on the side wall of the end of the extrusion shaft 7 away from the telescopic rod 3. A rotating ring 15 is rotatably connected in the rotating groove 14. A rotating shaft 8 is fixedly connected to one end of the rotating ring 15. One end of the rotating shaft 8 is rotatably connected to one end of the corresponding two horizontal connecting plates 10. The output end of the motor 4 extends into the discharge pipe 2 and is detachably connected to a drive shaft 9. One end of the drive shaft 9 and near both sides are rotatably connected to one end of the corresponding horizontal connecting plate 10.

[0019] The technical effect of this solution is as follows: When a blockage occurs, the telescopic rod 3 is activated to drive the extrusion shaft 7 to move. As the extrusion shaft 7 moves, it gradually extrudes the horizontal connecting plate 10. The extruded horizontal connecting plate 10 deforms, contracts, and opens, thus inserting itself into the blocked material. Then, the extrusion shaft 7 contracts, causing the unfolded horizontal connecting plate 10 to gradually merge into a horizontal state. This movement is repeated to insert and pull the blocked material in different ways, thus giving the blocked material room to fall downwards. At the same time, the motor 4 is activated to drive the horizontal connecting plate 10 to rotate via the drive shaft 9. In conjunction with the extension plate 12 and the cone plate 13, it can move the blocked material, thereby bringing the material out of the discharge pipe 2. As long as a certain amount of space is cleared, the material will fall down on its own, thus achieving the effect of preventing blockage.

[0020] A detachable outer cover box 5 is connected to one side wall of the hopper 1. A vibrating motor 6 is detachably connected to one side wall inside the outer cover box 5. One end of the vibrating motor 6 is attached to the outer wall of the hopper 1.

[0021] The technical effect of this solution is as follows: an outer cover box 5 is connected to one side wall of the hopper 1, and a vibration motor 6 is connected inside the outer cover box 5. When needed, the vibration motor 6 can be started to make the side wall of the hopper 1 vibrate. With the vibration, the blocked material can be vibrated and cleared. In conjunction with components such as the horizontal connecting plate 10, the clearing and anti-blocking effect can be effectively improved. At the same time, the vibration can also discharge the side wall adhering to the inner wall of the hopper 1, ensuring the output rate of the material and avoiding the impact on the subsequent material.

[0022] Specifically, when this utility model is used, if a blockage occurs, the telescopic rod 3 is activated first. The telescopic rod 3 pushes the extrusion shaft 7 to extrude the two pairs of horizontal connecting plates 10. The horizontal connecting plates 10 will be folded and deformed under pressure, thus inserting into the blockage material. At this time, the motor 4 drives the horizontal connecting plates 10 to rotate via the drive shaft 9, thereby pushing the blockage material downwards and discharging the blockage material into a space. With this space, the material that caused the blockage due to mutual compression will be discharged under the action of gravity, thus achieving the cleaning effect. Timed activation can effectively prevent blockages from occurring, and the vibration motor 6 can be activated to vibrate the hopper 1 to cooperate with the anti-blockage and improve the cleaning effect.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
