Description

Technical Field

[0001] The utility model relates to the technical field of rubber production equipment, in particular to a vertical spiral upper feeder for rubber production. Background Technique

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under very small external force, and can return to its original state after the external force is removed. During the production of rubber, a vertical spiral upper feeder is often used to transfer materials from a lower place to a higher place for production.

[0003] After retrieval, the Chinese utility model patent with the publication number of CN212291661U discloses a vertical spiral upper feeder for rubber production, which includes fastening bolts, a first hydraulic telescopic rod, a cross plate, a pulley, a buffer pad, a sliding rod, a fixed column, a support seat, an anti-wear pad, a support rod, a stop rod, a fixed seat, a motor, a support column, a belt, a feed pipe, a lid, a feeding box body, a discharge pipe, a spiral shaft, a stop block, a sleeve, a discharge pipe, a second hydraulic telescopic rod, a bottom plate, a connecting rod and a protrusion. The four corners of the bottom end of the bottom plate are respectively fixedly connected with the top ends of the support seats through bolts. The number of the sliding rods is two and they correspond to each other. The other sides of the sliding rods corresponding to the fixed seats are respectively adhesively bonded with one side of the buffer pads. This utility model has a simple structure and is convenient to use, which is beneficial to avoiding the tipping of this utility model due to the upward shift of the center of gravity during the vertical spiral feeding process, and is also beneficial to cleaning the rubber production raw materials inside the feeding box body when the conveying is completed.

[0004] In the above technical solution, the material is directly fed through the feed pipe. During the feeding process, when the materials are squeezed against each other, when the materials are rubber particles, the friction between the rubber particles is relatively large, and the feed pipe is prone to blockage and poor feeding, which affects the feeding of the vertical spiral and is prone to the problem of uneven feeding.

One side of the bottom of the bottom support plate is provided with a driving motor. One end of the power output shaft of the driving motor is provided with a first pulley. Above the first pulley on the outer wall of the support frame is provided a feed support. The top of the feed support is provided with an elastic telescopic rod. The top of the elastic telescopic rod is provided with a feed hopper. One end of the feed hopper is provided with a feed pipe.

[0011] Further, the top end of the elastic telescopic rod is hinged to the feed hopper, and the bottom end is fixedly connected to the feed support.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By providing the support frame, the feed support and the feed hopper, the present utility model realizes that when the vertical screw upper feeder for rubber production is used, the driving motor drives the first pulley to rotate, and the second pulley is driven to rotate through the transmission of the transmission belt, so that the spiral conveying knife in the vertical screw conveyor rotates to lift the material.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 the embodiments.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a vertical spiral feeding auxiliary machine for rubber production, including: a support frame 1 and a vertical screw conveyor 2. The vertical screw conveyor 2 is fixedly arranged inside the support frame 1. A bottom support plate 3 is arranged on one side of the lower half of the support frame 1. A drive motor 4 is arranged on one side of the bottom of the bottom support plate 3. One end of the power output shaft of the drive motor 4 is provided with a first pulley 5. A feeding bracket 6 is arranged on the outer wall of the support frame 1 above the first pulley 5. An elastic telescopic rod 7 is arranged at the top of the feeding bracket 6. The top of the elastic telescopic rod 7 is provided with a feeding hopper 8. One end of the feeding hopper 8 is provided with a feeding pipe 15. A connecting hose 16 is arranged between the feeding pipe 15 and the vertical screw conveyor 2. During the feeding process of the material, the material in the feeding hopper 8, due to the inclined bottom surface of the feeding hopper 8, the material enters the feeding pipe 15 under the action of gravity. At the same time, with the rotation of the drive motor 4, the first pulley 5 drives the top shaft 9 to rotate. The top shaft 9 drives the support plate 13 and the convex block 14 to rotate. Due to the eccentric installation of the convex block 14, the convex block 14 can collide with the convex plate 10 on the feeding hopper 8 periodically, driving the feeding hopper 8 to vibrate, driving the material in the feeding pipe 15 to discharge quickly, preventing blockage, and improving the feeding efficiency and feeding uniformity.

[0021] A spiral conveyor blade is arranged in the center of the vertical screw conveyor 2. A feeding port is opened on one side of the lower half of the vertical screw conveyor 2. One end of the feeding port is fixedly connected with one end of the connecting hose 16. A discharge pipe 17 is arranged on one side of the upper half of the vertical screw conveyor 2.

[0022] The bottom end of the spiral conveyor blade is fixedly provided with a second pulley 11. A transmission belt 12 is arranged between the second pulley 11 and the first pulley 5. Through the transmission of the transmission belt 12, the second pulley 11 is driven to rotate, so that the spiral conveyor blade in the vertical screw conveyor 2 rotates to lift the material.

[0023] A top shaft 9 is provided at the center of the top of the first pulley 5. A support plate 13 is provided at the top end of the top shaft 9. A convex block 14 is provided on one side of the top of the support plate 13. A convex plate 10 is provided at the bottom of the feed hopper 8 above the convex block 14. The first pulley 5 drives the top shaft 9 to rotate. The top shaft 9 drives the support plate 13 and the convex block 14 to rotate. Due to the eccentric installation of the convex block 14, the convex block 14 and the convex plate 10 on the feed hopper 8 can collide periodically.

[0024] The bottom surface of the feed hopper 8 is inclined. One end of the feed pipe 15 is close to the bottommost end of the bottom surface of the feed hopper 8, facilitating the material to fall into the feed pipe 15 by gravity.

[0025] The top end of the elastic telescopic rod 7 is hinged to the feed hopper 8, and the bottom end is fixedly connected to the feed support 6. When the feed hopper 8 vibrates, relative displacement will occur between the feed hopper 8 and the elastic telescopic rod 7, and the hinge can prevent movement interference.

[0026] Working principle: When the vertical spiral upper auxiliary machine for rubber production is in use, the driving motor 4 drives the first pulley 5 to rotate. The second pulley 11 is driven to rotate through the transmission of the transmission belt 12, so that the spiral conveyor blade in the vertical spiral conveyor 2 rotates to lift the material. During the material feeding process, the material in the feed hopper 8, due to the inclined bottom surface of the feed hopper 8, the material enters the feed pipe 15 by gravity. At the same time, with the rotation of the driving motor 4, the first pulley 5 drives the top shaft 9 to rotate. The top shaft 9 drives the support plate 13 and the convex block 14 to rotate. Due to the eccentric installation of the convex block 14, the convex block 14 and the convex plate 10 on the feed hopper 8 can collide periodically, driving the feed hopper 8 to vibrate, driving the material in the feed pipe 15 to discharge quickly, preventing blockage, and improving the feeding efficiency and feeding uniformity.

[0027] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
