Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0021] In the embodiments, such as Figure 1-4 As shown, a vacuum tumbler includes a detachably connected frame 1 and a drum assembly 2. The frame 1 houses a vacuum pump and a drive motor. The drum assembly 2 includes a drum body 2.1 and an openable / closable sealing cover 2.2. A drive shaft 2.3 is fixed to the center of the bottom of the drum body 2.1. The inner wall of the drum body 2.1 is provided with several detachable blades 2.4 extending axially along its circumference. The sealing cover 2.2 is provided with a vacuum connector equipped with a valve 2.5. The frame 1 is provided with a drive sleeve 1.1 that is connected to the output end of the drive motor. The drive shaft 2.3 can be inserted into the drive sleeve 1.1 to achieve power coupling. The frame 1 is also provided with at least two support wheels 1.2 for supporting the outer wall of the drum body 2.1. By designing the frame 1 and the drum assembly 2 to be detachably connected and integrating the vacuum pump and drive motor inside the frame 1, the overall structure of the machine is compact. The detachable blades 2.4 on the inner wall of the drum body 2.1 greatly facilitate cleaning. The insertion coupling method between the drive shaft 2.3 and the drive sleeve 1.1, combined with the auxiliary support of the support wheel 1.2, makes the loading and unloading of the roller assembly 2 simple and quick, while ensuring the stability of power transmission.

[0022] In the embodiments, such as Figures 2-3As shown, a radial pin 1.3 is provided inside the transmission sleeve 1.1, and a U-shaped groove 2.6 with a guide chamfer 2.7 is provided at the end of the transmission shaft 2.3 to accommodate the pin 1.3. The radial pin 1.3 inside the transmission sleeve 1.1 and the U-shaped groove 2.6 with a guide chamfer 2.7 at the end of the transmission shaft 2.3 allow the user to install the roller without precisely aligning the angle. After roughly aligning, the pin 1.3 can slide into the bottom of the U-shaped groove 2.6 under the guidance of the guide chamfer 2.7, achieving circumferential fixation. This greatly simplifies the operation steps and improves assembly efficiency and reliability.

[0023] In the embodiments, such as Figures 2-3 As shown, the inner wall of the transmission sleeve 1.1 is provided with a PTFE washer 1.4 that mates with the outer wall of the transmission shaft 2.3. The PTFE washer 1.4 on the inner wall of the transmission sleeve 1.1, mates with the outer wall of the transmission shaft 2.3, providing a good fixing effect. At the same time, the PTFE material has self-lubricating and wear-resistant properties, reducing friction and wear between the transmission shaft 2.3 and the transmission sleeve 1.1, and improving the service life of the transmission components.

[0024] In the embodiments, such as Figure 4 As shown, there are three blades 2.4, evenly distributed on the inner wall of the cylinder body 2.1. Limiting the number of blades 2.4 to three and evenly distributed has been experimentally verified to ensure effective lifting and tumbling of materials to achieve the best tumbling effect, while avoiding material flow obstruction or damage caused by too many blades, thus achieving a balance between efficiency and effectiveness.

[0025] In the embodiments, such as Figure 4 As shown, the blade 2.4 has several hooks 2.8 facing the same direction along its length, and the inner wall of the cylinder body 2.1 has several pins 2.9 with protruding heads. The hooks 2.8 are secured within the protruding heads of the pins 2.9. This detachable connection method, where the hooks 2.8 and the protruding heads of the pins 2.9 are mutually secured, allows for the installation and removal of the blade 2.4 without any tools, and can be completed by hand, making the operation extremely simple. This connection method ensures the stability of the blade 2.4 during operation while also meeting the need for frequent disassembly for thorough cleaning.

[0026] In the embodiments, such as Figure 2As shown, the vacuum port of the vacuum pump and the end of the vacuum connector are respectively equipped with a first quick-connect fitting 1.5 and a second quick-connect fitting 2.10, and an air tube 3 is connected between the first quick-connect fitting 1.5 and the second quick-connect fitting 2.10. By connecting the air tube 3 between the first quick-connect fitting 1.5 and the second quick-connect fitting 2.10, one-button quick connection and disconnection of the vacuum circuit can be achieved. This connection method eliminates the tedious threading process, has high operational efficiency, and the quick-connect fitting has a built-in sealing ring, which can effectively ensure the sealing reliability of the vacuum circuit.

[0027] In the embodiments, such as Figures 1-4 As shown, the sealing cap 2.2 is made of transparent material and is locked and fixed to the open end of the cylinder body 2.1 by multiple snap fasteners 2.11. The sealing cap 2.2 can be made of transparent materials such as polycarbonate (PC), polymethyl methacrylate (PMMA), or high-strength polystyrene (PS). Users can directly observe the tumbling state and color changes of the material inside the cylinder body 2.1 without opening the sealing cap 2.2, which facilitates process monitoring and adjustment. The locking and fixing by the snap fasteners 2.11 ensures the sealing performance of the sealing cap 2.2, and its opening and closing operation is faster and less labor-intensive than the traditional bolt tightening method.

[0028] In the embodiments, such as Figure 3 As shown, the bottom of the drum body 2.1 is provided with a downward-protruding annular skirt 2.12, the height of which is greater than the downward-protruding length of the drive shaft 2.3. When the drum assembly 2 is detached from the frame 1 and placed upright on the ground or workbench, the skirt 2.12 contacts the workbench first, suspending the drive shaft 2.3 in the air. This prevents the ends of the drive shaft 2.3, especially critical parts such as the U-shaped groove 2.6, from being damaged by impacts, and also increases the stability of the upright placement.

[0029] In the embodiments, such as Figures 1-2 As shown, the frame 1 is equipped with an operation panel 1.6, which includes a status display panel for setting and displaying working parameters, as well as operating switches for the vacuum pump and drive motor. Specifically, it includes a vacuum gauge 1.7, a total time display screen 1.8, a working / pause time parameter screen 1.9, a power button 1.10, a speed control knob 1.11, a vacuum rotary switch 1.12, and a start button 1.13. The operation panel 1.6 integrates the status display panel and various operating switches. In addition to directly performing start / stop operations, users can set process parameters such as total working time, running time, and pause time, and monitor the equipment's operating status in real time. This integrated design makes operation centralized and intuitive, greatly improving the convenience of human-machine interaction and the degree of automation in equipment control.
