Description

TECHNICAL FIELD

[0002] In traditional industrial production, various pollutants such as oil, oxide and dust often exist on the surface of materials, which can seriously affect the quality of subsequent processes, for example, reduce the bonding strength of materials and affect the uniformity of coatings. In order to solve these problems, plasma cleaning technology has gradually developed. Plasma cleaning has the advantages of good cleaning effect, no residue and environmental friendliness. However, in actual production, many workpieces to be cleaned have complex shapes and various sizes, making it difficult for traditional flat plasma cleaning equipment to meet the needs of uniform cleaning. The drum type plasma cleaning machine is developed on the basis of plasma cleaning technology. The drum type design has unique advantages. The drum type design can make the workpieces continuously tumble in the drum, thereby ensuring that each surface of each workpiece can be fully exposed to the plasma. However, during use, the tumbling effect of flat and complex structure materials inside the drum is poor, making it difficult for the drum to effectively tumble the materials inside it. This results in uneven cleaning of flat and complex structure materials, and when cleaning complex structure materials, the dust inside the materials cannot be discharged, requiring the materials to be removed for dust removal treatment, increasing the working steps and affecting the processing efficiency.

[0031] Further referring to Figure 3 and Figure 8It is explained that in the process of continuously switching the horizontal and vertical of the cleaning cavity 15, when the cleaning cavity 15 is switched from horizontal to vertical, the cleaning ring 23 drives the sliding block one 221 and the sliding ring 231 to move to the sliding block two 222 through the counterweight 232, at this time the cleaning ring 23 pulls the flexible strip 22, so that the flexible strip 22 twists with the cylinder sieve 153, through the twisting of the flexible strip 22, the material is uniformly distributed on the side wall of the sliding block two 222, improving the uniformity of the material plasma cleaning, when the cleaning cavity 15 is switched from vertical to horizontal, the spring one 212 is released, the cleaning ring 23 drives the sliding block one 221 and the sliding ring 231 to return to the original position, when the sliding block one 221 returns to the original position, the sliding block one 221 pulls the flexible strip 22, so that the flexible strip 22 moves rapidly with the material, through the movement of the flexible strip 22, the material is quickly and uniformly distributed in the inside of the cylinder sieve 153, improving the uniformity and efficiency of the material plasma cleaning, at this time the cleaning ring 23 is reversed through the pulling of the torsion spring and the flexible strip 22, so that the cleaning ring 23 is reversed in the process of returning to the original position, through the cleaning ring 23 cleaning the inner wall of the cylinder sieve 153, the dust on the side wall of the cylinder sieve 153 is discharged, avoiding the cylinder sieve 153 from being blocked, improving the cleanliness of the inside of the cylinder sieve 153.

[0032] The specific working principle and use method of the present invention are explained in detail below: after the material is filled into the interior of the cylindrical screen 153, the vacuum device evacuates the interior of the shell 1, and after the vacuum detector 14 responds, the plasma device 21, the electric push rod 133 and the motor 161 are started, and the motor 161 drives the cylindrical screen 153 to rotate, and the cylindrical screen 153 drives the side plate 155 and the side plate 2 156 to rotate, and the side plate 155 and the side plate 2 156 follow the cylindrical screen 153 to rotate, so that the material rolls during the rotation of the cylindrical screen 153, thereby improving the uniformity of the plasma cleaning of the material, and at the same time, the rolling of the material hits the cylindrical screen 153, thereby cleaning the dust on the side wall of the cylindrical screen 153, and During the rotation of 153, the side wall rollers 223 of slide 1 221 and slide 2 222 rotate, causing the flexible strip 22 to rotate in the same direction as the cylindrical screen 153. The material is thrown upward by the rotation of the flexible strip 22, increasing the height of the material rolling and increasing the collision force between the materials and between the materials and the cylindrical screen 153, thereby further improving the cleaning of the dust inside the cylindrical screen 153 and the dust on the surface of the material. When the side plate 2 156 contacts the spring top block 234, the cleaning ring 23 rotates with the cylindrical screen 153 and pulls the top and bottom flexible strips 22. The slide 1 221 moves toward the slide 2 222, increasing the rotation range of the remaining flexible strips 22. When the top and bottom flexible strips 22 are tightened, the cleaning ring 23 is returned to its original position by the torsion spring, and the slide 1 221 and the slip ring 231 are returned to their original position by the spring 1 212. The intermittent rotation of the cleaning ring 23 increases the rotation range of the flexible strip 22 intermittently, thereby increasing the coverage range of the flexible strip 22 and the height of the material rolling, and further improving the uniformity of the plasma cleaning of the material. The electric push rod 133 drives the cleaning chamber 15 to be continuously horizontally and vertically positioned, so that the material inside the cylindrical screen 153 rolls and shakes. The state of the continuous switching of the cleaning chamber 15 increases the frequency and strength of the material rolling inside the cylindrical screen 153, and further improves the uniformity of the plasma cleaning of the material. When the cleaning chamber 15 is switched from horizontal to vertical, the cleaning ring 23 drives the slide 1 221 and the slip ring 231 to the slide 2 through the counterweight block 232. 222 moves, at this time the cleaning ring 23 pulls the flexible strip 22, so that the flexible strip 22 twists along with the cylindrical screen 153, and the twisting of the flexible strip 22 makes the material evenly distributed on the side wall of the slide 222, thereby improving the uniformity of the plasma cleaning of the material. When the cleaning chamber 15 switches from vertical to horizontal, the spring 1 212 is released, and the cleaning ring 23 drives the slide 1 221 and the slip ring 231 to return to their positions. When the slide 1 221 returns to its position, the slide 1 221 pulls the flexible strip 22, so that the flexible strip 22 drives the material to move quickly. Through the movement of the flexible strip 22, the material is quickly and evenly distributed inside the cylindrical screen 153, thereby improving the uniformity and efficiency of the plasma cleaning of the material. At this time, the cleaning ring 23 is reversed by the pulling of the torsion spring and the flexible strip 22.The cleaning ring 23 is reversed during homing, the inner wall of the cylindrical screen 153 is cleaned by the cleaning ring 23, the dust on the side wall of the cylindrical screen 153 is discharged, the cylindrical screen 153 is prevented from being blocked, and the cleanliness inside the cylindrical screen 153 is improved.

[0033] Further, the fixed connection should be understood in a broad sense unless otherwise specified and limited, for example, it can be welding, or gluing, or integrally formed, and other conventional means familiar to those skilled in the art.
