Description

Technical Field

[0001] This utility model relates to the field of plastic powder processing technology, specifically to a plastic powder feeding and conveying device. Background Technology

[0002] In plastic processing, plastic powder often needs to be transported to processing equipment for further processing. Currently used feeding and conveying devices typically consist of a feeding hopper and a conveying pipe. Plastic powder enters from the feeding hopper and is transported to subsequent equipment through the conveying pipe. However, in actual use, due to the agglomerative nature of plastic powder, it easily accumulates and clogs in the feeding hopper, leading to uneven feeding, reduced feeding efficiency, and inconvenience to production.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. This utility model uses a motor to drive an incomplete gear to rotate. The incomplete gear meshes with a rack, causing the rack to move to the right, which in turn moves the feeding hopper to the right. During this process, the feeding hopper compresses a spring. When the incomplete gear separates from the rack, the spring elastically returns to its original position, pushing the feeding hopper to move to the left and return to its original position. By repeating the above actions, the feeding hopper can be moved back and forth left and right, shaking and feeding the plastic powder particles in the feeding hopper, effectively preventing feeding blockage.

A limiting mechanism is provided on the upper side of the feed shell 3 to restrict the movement of the mounting ring 15. A vertical plate 11 is fixedly installed in the middle of the upper surface of the auger 2. Two through holes are opened in the middle of the vertical plate 11. A sliding rod 7 is slidably sleeved inside the lower through hole. One end of the sliding rod 7 is fixedly connected to the outer wall of the feed hopper 5. A first spring 8 is movably sleeved on the rod wall of the sliding rod 7. The two ends of the first spring 8 are fixedly connected to the corresponding feed hopper 5 and the vertical plate 11, respectively. A transmission mechanism is provided on one side of the upper end of the vertical plate 11 to drive the feed hopper 5 to move horizontally.

[0024] Reference Figure 1-3The transmission mechanism includes a rack 9 and an incomplete gear 13. The rack 9 is slidably sleeved in the upper through hole of the vertical plate 11. One end of the rack 9 is fixedly connected to the feeding hopper 5. A side plate 10 is fixedly installed on the side wall of the vertical plate 11 above the rack 9. A rotating rod 12 is rotatably sleeved on the front side of the side plate 10. An incomplete gear 13 is fixedly sleeved at the front end of the rotating rod 12. The incomplete gear 13 meshes with the rack 9. A motor 14 is fixedly installed on the rear side of the side plate 10. The output end of the motor 14 is fixedly connected to the rear end of the rotating rod 12. Anti-slip blocks are fixedly installed on the side of the rack 9 and the sliding rod 7 away from the feeding hopper 5 to prevent the sliding rod 7 and the feeding hopper 5 from slipping out of the through hole as much as possible.

[0025] Reference Figure 1-3 The limiting mechanism includes a first insert rod 17 and a second insert rod 18. The two first insert rods 17 are fixedly disposed on both sides of the upper surface of the feed shell 3. The surface of the connecting ring 15 is provided with insertion holes at positions corresponding to the first insert rods 17. The first insert rods 17 are inserted into the corresponding insertion holes. A fixing plate 16 is fixedly disposed on the upper surface of the feed shell 3 on one side of the first insert rods 17. A sliding hole is provided on the upper side wall of the fixing plate 16. The second insert rod 18 is slidably sleeved inside the sliding hole. A second insertion hole is provided at the upper end of the first insert rod 17. One end of the second insert rod 18 is inserted into the second insertion hole. A baffle 19 is fixedly sleeved on the rod wall of the insert rod 18 between the fixing plate 16 and the first insert rod 17. A second spring 20 is fixedly connected between the baffle 19 and the fixing plate 16.

[0026] In this utility model, when using it to feed and convey plastic powder, the plastic powder is poured into the feeding hopper 5, the motor 14 and the auger 2 are started, the motor 14 drives the rotating rod 12 and the incomplete gear 13 to rotate, when the teeth of the incomplete gear 13 mesh with the rack 9, the rack 9 is pushed to move to the right along the upper through hole of the vertical plate 11, the rack 9 drives the feeding hopper 5 to move to the right in sync, the feeding hopper 5 pulls the sliding rod 7 to slide along the lower through hole, and at the same time compresses the first spring 8;

[0027] When the toothless part of the incomplete gear 13 rotates to be opposite to the rack 9, the two disengage, the first spring 8 returns to its elastic state, pushes the feeding hopper 5 to the left, and drives the rack 9 and slide bar 7 to return to their original positions. This process is repeated, and the feeding hopper 5 swings back and forth in the horizontal direction to prevent plastic powder particles from accumulating and clogging inside, and to ensure that the powder particles enter the elastic tube 6 smoothly.

[0028] The support ring on the inner wall of the elastic tube 6 ensures that it is not easy to collapse when it shakes with the feed hopper 5. The mounting ring 15 and the feed shell 3 are positioned by the insertion of the first insert rod 17. The second insert rod 18 is inserted into the second insertion hole of the first insert rod 17 under the action of the second spring 20, which strengthens the connection between the mounting ring 15 and the feed shell 3. The sealing ring enhances the sealing at the connection between the two to prevent powder particles from leaking out.

[0029] Plastic powder enters the feed housing 3 through the elastic tube 6, is conveyed to the upper end by the auger 2 and discharged from the discharge housing 4. The anti-detachment block prevents the rack 9 and slide bar 7 from coming out of the through hole of the vertical plate 11, ensuring stable transmission.

[0030] If it is necessary to clean the elastic tube 6 or the feed shell 3, pull the second insertion rod 18, the baffle 19 compresses the second spring 20, so that the second insertion rod 18 is dislodged from the second insertion hole, and the mounting ring 15 and the elastic tube 6 can be pulled out upwards. The operation is convenient. The entire device achieves anti-blocking feeding through the reciprocating shaking of the feeding hopper. With the help of the auger conveyor, the feeding efficiency is significantly improved.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
