[0002] In the production processes of food processing, meat curing, and material mixing and modification industries, vacuum tumblers serve as core material handling equipment. Their mixing uniformity, vacuum sealing, operational stability, and ease of operation directly affect the product's taste, flavor, quality consistency, shelf life, and production efficiency. This is especially true as various industries increasingly demand product standardization, large-scale production, and refined processes. CN210726552U discloses a small vacuum tumbling machine. Its key technical features include a base and a roller placed horizontally on the base. One end of the roller has a feed inlet, and a detachable cover is installed at the feed inlet to seal it. A transmission mechanism is provided between the roller and the base. The transmission mechanism includes rotating shafts positioned opposite each other on both sides below the roller. These shafts rotate horizontally along the roller's axis and are supported on the base. Friction wheels are fixedly mounted on the rotating shafts. The front and rear ends of the roller rest on the friction wheels on their respective sides. A drive mechanism is located at the end of the base away from the cover. This drive mechanism is connected to the transmission mechanism to drive the two rotating shafts to rotate in the same direction, thereby enabling the friction wheels on the shafts to drive the roller to rotate. The advantage of this invention is that it allows for convenient loading and unloading of raw meat, improving work efficiency. However, this equipment suffers from cumbersome and inefficient operation of fixing and disassembling the drum door, leading to prolonged downtime for material changes and affecting the continuity of the production line. Improvements are needed. Utility Model Content

[0010] The above-mentioned technical solutions of one or more of the vacuum tumblers provided in this embodiment of the utility model have at least one of the following technical effects: 1. In this utility model, by setting up components such as a machine frame, support frame, rotating shaft, friction wheel, and roller, the precise cooperation between the guide groove and guide rod achieves rapid positioning during the installation of the cylinder door. The fixing spring naturally extends to push the insertion rod out and lock the cylinder door to complete the initial fixation. The sealing ring simultaneously adheres to the roller port to ensure a vacuum sealing effect. The pressing plate, support spring, return spring, and return rod form a linkage structure. During disassembly, only pressing the pressing plate triggers the return spring to push the insertion rod to retract and disengage from the slot. The entire structure simplifies the operation process of fixing and disassembling the cylinder door through mechanical linkage and elastic cooperation, eliminating the need for complex tools or multiple cumbersome steps, significantly reducing equipment downtime for material change, and ensuring the continuity of the production line.

By holding the handle, the compression block can be pulled to compress the compression spring. After rotating the limiting rod to the outside of the cylinder door and releasing the handle, the compression spring returns to its original position and pushes the compression block to tightly fit the cylinder door. The limiting rod forms a mechanical block, realizing secondary reinforcement of the cylinder door. This effectively prevents the cylinder door from loosening due to vibration during equipment operation, further improving structural stability and operational safety. Attached Figure Description

[0018] In one embodiment of this utility model, such as Figures 1-5As shown, a vacuum tumbling machine is provided, including a frame 1, which provides stable support for the overall structure and ensures the stability of the equipment operation. A support frame 2 is fixedly installed on the surface of the frame 1, supporting the smooth rotation of the rotating shaft 3. A friction wheel 4 is fixedly installed on the surface of the rotating shaft 3, which drives the drum 5 to rotate through a contact transmission, ensuring efficient tumbling operation. The surface of the friction wheel 4 is in contact with the drum 5, providing a sealed tumbling space for the material and ensuring the vacuum processing effect. A fixing spring 6 is fixedly installed inside the drum 5, providing elastic thrust to ensure the precise engagement of the insertion rod 7 and the reliable fixation of the drum door 8. The insertion rod 7 is fixedly installed at one end of the fixing spring 6, which engages with the drum door 8 to achieve quick fixation and simplify the installation process. The surface of the insertion rod 7 engages with the drum door 8, achieving a sealed closure of the drum 5 opening for easy material loading and unloading. A support spring 9 is fixedly installed inside the drum door 8, providing elastic support for the pressing plate 10 to ensure smooth reset after pressing. The pressing plate 10 is fixedly installed at one end of the support spring 9, facilitating manual operation to trigger the reset mechanism and reducing disassembly difficulty. A reset spring 11 is fixedly installed inside the pressing plate 10, generating a reverse thrust to drive the insertion rod 7 to retract. The gate 8 unlocks quickly. A reset rod 12 is fixedly installed at one end of the reset spring 11 to transmit the force of the reset spring 11 and ensure synchronous movement of the insertion rod 7. A sealing ring 13 is fixedly installed on one side of the gate 8 to enhance the sealing performance between the gate 8 and the roller 5 and ensure no leakage in the vacuum environment. A guide groove 14 is fixedly installed on the side of the gate 8, which works with the guide rod 15 to achieve precise positioning of the gate 8 and improve installation efficiency. A guide rod 15 is provided on the inner surface of the roller 5 to guide the installation direction of the gate 8 and avoid misalignment and jamming. The inner surface of the roller 5 is slidably connected to the surface of the insertion rod 7 to reduce... The reduced resistance of the insertion rod 7 ensures smooth extension and retraction. The inner surface of the gate 8 is slidably connected to the side of the pressing plate 10, making the pressing plate 10 more evenly stressed and easier to operate. The surface of the reset rod 12 is slidably connected to the inner surface of the pressing plate 10, ensuring that the reset rod 12 can extend and retract flexibly and improve the unlocking response speed. The fixed spring 6, insertion rod 7, reset spring 11 and reset rod 12 are arranged in a ring array to distribute the force evenly and avoid uneven force on the gate 8. The support spring 9 is fixedly installed at the four corners of the pressing plate 10 to ensure that the pressing plate 10 is balanced and reset to prevent tilting and jamming.

[0019] In another embodiment of this utility model, a fixed frame 16 is fixedly installed at one end of the roller 5 of the vacuum tumbler, providing a stable installation base for the limiting rod 17 and enhancing the reliability of the anti-loosening structure. The limiting rod 17 is rotatably connected inside the fixed frame 16, which can be flexibly rotated to facilitate the blocking or unlocking operation of the cylinder door 8. A compression spring 18 is fixedly installed inside the limiting rod 17, providing continuous compression force to ensure that the compression block 19 fits tightly against the cylinder door 8. A compression block 19 is fixedly installed at one end of the compression spring 18, which directly acts on the surface of the cylinder door 8 to enhance the anti-loosening effect. A handle 20 is fixedly installed on one side of the compression block 19, which is convenient for manual pulling and adjustment to reduce the difficulty of operation. The surface of the compression block 19 is slidably connected to the inner surface of the limiting rod 17 to ensure that the compression block 19 extends and retracts smoothly and responds promptly. The compression spring 18 and the compression block 19 are symmetrically distributed to make the cylinder door 8 bear force evenly and avoid local wear or loosening.

[0020] Working principle: Align the gate 8 with the opening of the roller 5, align the guide rod 14 on the side of the gate 8 with the guide groove 15 on the inner surface of the roller 5, and slowly push it in until it is completely closed. At this time, the fixing spring 6 inside the roller 5 naturally extends, pushing the insert rod 7 out and into the corresponding groove of the gate 8, thus initially fixing the gate 8 and ensuring that the sealing ring 13 on one side of the gate 8 is tightly fitted to the end of the roller 5 to ensure a vacuum seal. Then, grasp the handle 20 next to the fixing bracket 16 and pull it outward, which will cause the compression block 19 to compress the compression spring 18 inside the limiting rod 17. After rotating the limiting rod 17 to the outer end face of the gate 8, release the handle 20, and the compression spring 18 will be compressed. 8. The elastic deformation pushes the extrusion block 19 to tightly press the surface of the cylinder door 8. The mechanical obstruction of the limit rod 17 prevents the cylinder door 8 from becoming loose due to vibration when the roller 5 rotates and rolls. When disassembling, first hold the handle 20 and pull the extrusion block 19 to compress the extrusion spring 18. Then rotate the limit rod 17 in the opposite direction to release the limit obstruction on the cylinder door 8. Next, press the pressing plate 10 on the cylinder door 8. The pressing plate 10 compresses the support spring 9 and triggers the reset spring 11. The reset spring 11 generates a thrust to push the insertion rod 7 to retract into the roller 5. After the insertion rod 7 disengages from the slot of the cylinder door 8, it is pulled out of the cylinder door 8 along the direction of the guide rod 14 and the guide groove 15 to complete the disassembly.
