Description

Technical Field

[0001] This utility model relates to the field of recycled rubber production technology, specifically to a feeding device for a refining mill used in recycled rubber production. Background Technology

[0002] Reclaimed rubber refers to waste vulcanized rubber that has undergone physical and chemical processes such as crushing, heating, and mechanical treatment. After crushing, the old rubber waste needs to be transported to the center of the refining mill rollers via a feeding device.

[0003] Application number CN202123039267.6 discloses a feeding device for a recycled rubber refining mill. Through a sliding seat, a feeding hopper, and a first feeding cylinder, raw materials falling from the discharge hole accumulate in the feeding hopper and slide along a guide groove to the center of the feeding hopper under gravity, thus falling into the middle of the roller. This conforms to the working principle of the main refining mill. Furthermore, adjusting the position of the slider in the chute can adjust the size of the feeding hopper opening, facilitating control of the flow rate at the feeding hopper opening. Additionally, when the feeding screw shaft rotates, the stirring blades agitate the raw materials inside the feeding hopper. The mixing process keeps the raw materials inside the hopper loose, facilitating feeding. The rotating locking stud separates one end from the rotating roller under the push of the threads. At this point, the locking stud loses its fixing effect on the rotating roller, allowing the sliding seat to be pulled outwards via the rotating roller, further pulling out the No. 1 and No. 2 feeding cylinders. The No. 1 and No. 2 feeding cylinders are then pulled out of the insertion holes, and the hopper can be directly pulled upwards. This facilitates individual maintenance of the hopper, No. 1 feeding cylinder, and No. 2 feeding cylinder, further improving equipment production efficiency and saving maintenance time and costs.

[0004] The recycled rubber refining mill feeding device disclosed in the above patent can only convey materials to a fixed height through the feeding components. It can only be used for feeding refining mills of the same model and height, and cannot be used for feeding refining mills of different heights. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding device for a refining mill in the production of recycled rubber.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 The figure shows a feeding device for a refining mill used in the production of recycled rubber, including a drive frame 3. A conveyor belt 1 is installed on the inner wall of the drive frame 3 through a transmission assembly. Several limiting crossbars 2 are fixedly installed in an equidistant array on the outer wall of the conveyor belt 1. Rotating shafts 10 are fixedly installed on the left and right sides of the lower part of the drive frame 3 and are rotatably connected to the inner wall of the mounting frame 5 through the rotating shafts 10. The power input end of the rotating shaft 10 on the right end is connected to the power output end of a deceleration self-locking rotary drive assembly. Retractable support assemblies are hinged on the left and right sides of the upper part of the drive frame 3. An infrared ranging sensor 15 is installed on the upper right side of the drive frame 3. The feeding device for a refining mill used in the production of recycled rubber disclosed in this utility model can drive the feeding assembly to rise or fall through the deceleration self-locking rotary drive assembly. With the help of the retractable support assembly at the other end, the material can be conveyed to different heights by the feeding assembly, which is suitable for automated feeding of refining mills of different heights.

[0020] Furthermore, a feed hopper 4 is fixedly installed at the top of the lower end of the drive frame 3 for convenient feeding; furthermore, a track is fixedly connected to the inner wall of the conveyor belt 1, and the upper and lower ends of the track are meshed with track drive wheels, which are driven by a transmission drive motor installed inside the drive frame 3 for convenient drive transmission; furthermore, the deceleration self-locking rotary drive assembly includes a first gear 6 locked to the end of the right-end rotating shaft 10, a second gear 8 meshing to the outer wall of the first gear 6, the power input end of the second gear 8 being connected to the power output end of the motor 9, and an angle sensor 7 installed outside the right-end rotating shaft 10 for convenient drive; furthermore, the diameter of the first gear 6 is larger than that of the second gear 8, and the motor 9 is a self-locking motor for convenient deceleration drive; furthermore, the telescopic support assembly includes an electric telescopic rod 12 hinged to the left and right sides of the upper part of the drive frame 3 through a hinge assembly 13 and a support plate 14, and a support foot 11 fixedly installed at the bottom of the electric telescopic rod 12 for stable support.

[0021] In this solution, during use, the feeding device for a refining mill in recycled rubber production disclosed in this utility model can drive the feeding component to rise or fall through a deceleration self-locking rotary drive component. Combined with the retractable support component at the other end, the material can be conveyed to different heights by the feeding component. It is suitable for automated feeding of refining mills of different heights. When feeding to a higher position is required, an external power supply is used to turn on the motor 9 via an external switch and control the motor 9 to rotate clockwise. The motor 9 drives the second gear 8 to rotate clockwise. Since the second gear 8 is externally meshed with the larger diameter first gear 6, the first gear 6 rotates synchronously and slowly counterclockwise. The rotating shaft 10, conveyor belt 1, and limit switch... The feeding assembly, consisting of the horizontal bar 2 and the drive frame 3, rotates counterclockwise and slowly rises. The angle sensor 7 can detect the rising angle of the feeding assembly. After reaching the required angle, the external power supply turns on the electric telescopic rod 12 through an external switch and controls its extension to support the feeding assembly. The infrared distance sensor 15 can detect the distance between the upper and lower parts of the drive frame 3 and the ground, thereby intelligently driving the electric telescopic rod 12 to extend the corresponding length for stable support. When it is necessary to feed material to a lower position, the motor 9 is controlled to reverse, with the same principle as above (the angle sensor 7, motor 9, electric telescopic rod 12, and infrared distance sensor 15 are all existing products on the market).
