Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically a rubber compound lifting device. Background Technology

[0002] Rubber compound is an important semi-finished material in the production of rubber products. After its preparation, it usually needs to be transferred from the discharge port of the internal mixer at the ground or low position to the high-level storage area or the feeding port of the next process.

[0003] Currently, fixed elevators or conveyor belts are commonly used in industrial production to lift materials vertically or at an incline. However, existing lifting equipment often has the following shortcomings: First, the lifting containers (such as hoppers) are mostly fixed structures. After lifting and tilting are completed, it is difficult to quickly and thoroughly clean the sticky adhesive residue on the inner wall of the container. Long-term use can easily lead to material accumulation and cross-linking, affecting the quality of subsequent batches of materials. Secondly, the hoppers of existing equipment are usually rigidly connected to the lifting mechanism, which is inconvenient to disassemble, replace or maintain. When different types or colors of rubber materials need to be processed, cross-contamination is easy to occur. In addition, common hopper fixing methods (such as bolt fastening) are cumbersome to operate and have low efficiency during frequent loading and unloading, making it difficult to adapt to the fast-paced requirements of continuous production.

Detailed Implementation

[0013] 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.

[0014] like Figures 1 to 3 As shown, this utility model embodiment provides a rubber compound lifting device, which is mainly used to lift the rubber compound from a low position (such as the discharge port of an internal mixer) and pour it to a high-level device or storage area.

[0015] The lifting device provided in this embodiment includes a horizontally placed rectangular base plate 1. Two inclined rails 2 are symmetrically installed on the upper surface of the base plate 1 along the front-to-back direction. These two inclined rails 2 constitute the main guide rails for the lifting and operation of the tipping bucket 4. Below each inclined rail 2, near the base plate 1, an L-shaped tilting rail 3 is fixedly installed. The longer straight side of the tilting rail 3 is parallel to the inclined rail 2, while its bent end guides the tipping bucket 4 to complete the tilting and tipping action. The lower surface of the tilting rail 3 is firmly connected to the base plate 1 by a rigid bracket 11. The inclined rails 2 and the tilting rail 3 below together define the movement trajectory of the tipping bucket 4, including rising, tilting, falling, and resetting.

[0016] The tipping bucket 4 provided in this embodiment adopts a double-layer separable structure, specifically including an outer frame structure—outer shell 41, and an inner container for directly holding materials—inner shell 42. The inner shell 42 is detachably installed inside the outer shell 41 by a quick-clamping mechanism.

[0017] Specifically, the top of the side wall of the inner shell 42 is folded outward to form a U-shaped flange 421. During installation, the flange 421 is movably fastened to the top of the side wall of the outer shell 41 from top to bottom, providing initial positioning and support. In order to securely lock the inner shell 42 onto the outer shell 41, a set of clamping components 5 is provided on both the front and rear sides of the outer shell 41.

[0018] Each clamping assembly 5 includes a worm gear 51, a worm wheel 55, a rotating rod 54, and multiple locking blocks 56. A support block 52 is fixedly installed on the right side of both the front and rear sides of the outer casing 41. A worm gear 51 is horizontally rotatable between these two support blocks 52, with one end extending and connected to a handwheel 53 for easy manual rotation by the operator. Multiple fixing blocks 57 are also fixedly welded to the front and rear side walls of the outer casing 41. A rotating rod 54 is rotatably connected to the corresponding fixing block 57 in the left-right direction (i.e., perpendicular to the worm gear 51). The right end of the rotating rod 54 is fixedly connected to the aforementioned worm wheel 55, which is engaged with the aforementioned worm gear 51. Several locking blocks 56 are fixedly installed on the rod body of the rotating rod 54, and several locking slots 422 are opened on the flange 421 of the inner casing 42, with the number and position of the locking blocks 56 corresponding to the locking slots 422.

[0019] When it is necessary to fix the inner shell 42, the operator rotates the handwheel 53 clockwise, driving the worm gear 51 to rotate, which in turn drives the worm wheel 55 meshing with it to rotate. The worm wheel 55 drives the rotating rod 54 to rotate, causing the locking block 56 fixed on it to rotate at a certain angle (e.g., 90 degrees) and snap downwards into the corresponding slot 422 on the flange 421 of the inner shell 42, thereby firmly pressing and fixing the inner shell 42 onto the outer shell 41. Conversely, rotating the handwheel 53 counterclockwise will cause the locking block 56 to flip and disengage from the slot 422, releasing the constraint on the inner shell 42. At this time, the inner shell 42 can be lifted as a whole for cleaning or replacement. The worm gear mechanism has a self-locking characteristic, which ensures that the locking block 56 will not loosen due to vibration when pressed, making it safe and reliable.

[0020] To enable the tipping bucket 4 to run on the track, a lifting shaft 64 is rotatably mounted on the left side wall of the outer casing 41. Correspondingly, a drive assembly 6 for driving the tipping bucket 4 to rise and fall is set on the inclined track 2. The drive assembly 6 includes a drive motor 61, two drive shafts 63, and a chain 65. A drive shaft 63 is rotatably mounted at the upper and lower ends of the inclined track 2. A sprocket 62 is fixedly mounted at both ends of each drive shaft 63. The upper and lower sprockets 62 located on the same side (front or rear) are connected by a closed chain 65. The drive motor 61 is mounted on one side of the lower end of the inclined track 2, and its output shaft is coaxially connected to the lower drive shaft 63 to provide power. The two ends of the lifting shaft 64 of the tipping bucket 4 are fixedly connected to specific links of the two chains 65 (one at the front and one at the rear). When the drive motor 61 starts, it drives the chain 65 to rotate cyclically, thereby pulling the entire tipping bucket 4 up or down along the inclined track 2 via the lifting shaft 64.

[0021] To enable automatic tipping of the bucket 4 at the top, a pulley shaft 43 is rotatably mounted on the left side wall of the outer casing 41, above the lifting shaft 64. Each end of the pulley shaft 43 has a pulley (not labeled in the figure), which rolls within the grooves of the L-shaped tipping tracks 3 on both sides. When the bucket 4 is lifted to the top of the inclined track 2 by the chain 65, the pulley shaft 43 and its pulleys enter the bent section at the end of the tipping track 3. Guided by the bent section, the bucket 4 tilts forward with the lifting shaft 64 as the fulcrum, emptying the compounded rubber material from the inner casing 42. After tipping, the drive motor 61 reverses, and the bucket 4, under gravity and chain traction, descends along the track and returns to its original position.

[0022] To facilitate the positioning and movement of the inner shell 42 within the outer shell 41, small rollers (not shown in the figure) are installed at the four corners of the outer bottom surface of the inner shell 42. Simultaneously, several return springs (not shown in the figure) are fixedly installed on the inner bottom surface of the outer shell 41. When the inner shell 42 is inserted into the outer shell 41, the rollers make its movement easier, while the return springs provide a slight upward elastic force. This helps the inner shell 42 to fit tightly against the flange 421 at the top of the outer shell 41, and also allows the inner shell 42 to be slightly lifted after the clamping assembly 5 is released, making it easier for the operator to grasp and remove it.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
