Technical Field

[0001] The utility model relates to the technical field of porcelain processing equipment, in particular to a protective dust adsorption device. Background Art

[0002] Celadon, as a treasure of China's ceramic firing technology, has great ornamental and collection value. During the celadon processing, the initially formed porcelain blanks need to be trimmed after a period of airing to make the surface of the porcelain blanks smooth and uniform. However, during the polishing and trimming process, a large amount of dust will be generated, which is harmful to the health of the workers. If they are in a dusty environment for a long time, they are prone to pneumoconiosis, which affects their lives. At present, most people wear masks to protect against dust, but this does not provide good protection. Therefore, there is an urgent need for a device that can solve the problem of dust dispersion during processing. Utility Model Content

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] 1.

DETAILED DESCRIPTION

[0028] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0029] Specific implementation method 1: Combination Figure 1-7 As shown, a protective dust adsorption device includes: a stand 1, an air suction channel 101 is provided above the stand 1, a transmission screw 102 is provided at the rear of the stand 1, and a control motor is installed at the upper end of the transmission screw 102; a displacement portion 2, the interior of the displacement portion 2 is a hollow structure, the upper portion of the displacement portion 2 is connected to the air suction channel 101, the rear portion of the displacement portion 2 is threadedly connected to the transmission screw 102, and the displacement portion 2 is displaced in the height direction under the drive of the transmission screw 102, and a negative pressure portion 3 is provided in front of the displacement portion 2, and an annular air suction pipe 4 is provided on the negative pressure portion 3;

[0030] A negative pressure device is connected above the suction channel 101. During operation, the transmission screw 102 is controlled to rotate to drive the suction pipe 4 to adjust to an appropriate height, generally about 10 cm above the upper end surface of the porcelain blank. Subsequently, during the porcelain blank trimming process, the powder generated is sucked by the negative pressure force and passes through the air inlet holes evenly arranged below the suction pipe 4, so that the dust enters the negative pressure part 3 and is then discharged from the suction channel 101, effectively ensuring the safety of the staff and avoiding the occurrence of pneumoconiosis.

[0031] The preferred embodiment, combined with Figure 3 As shown, a sleeve tube 201 connected to the air intake channel 101 is provided above the displacement portion 2. The sleeve tube 201 is inserted into the air intake channel 101 and can slide along the air intake channel 101 while ensuring connectivity. In order to improve the tightness of the connection between the sleeve tube 201 and the air intake channel 101, multiple sealing rings can also be provided at the upper end of the sleeve tube 201 to improve the sealing.

[0032] The preferred embodiment, combined with Figure 3 and Figure 6As shown, a slide groove 103 is symmetrically provided below the stand 1; sliders 202 are provided on both sides of the displacement part 2, and a sliding connection is formed between the sliders 202 and the slide groove 103, which can effectively improve the stability of the displacement part 2 during height adjustment.

[0033] The preferred embodiment, combined with Figure 3 and Figure 7 As shown, two guide columns 301 are symmetrically welded on both sides of the negative pressure part 3, and a sliding hole is provided in the middle of the slider 202. The guide column 301 is inserted into the sliding hole to form a sliding connection. At the same time, the exhaust hole in the middle of the negative pressure part 3 is connected with the displacement part 2 through a pipeline; by pulling the negative pressure part 3 to move, the guide column 301 is displaced along the sliding hole, thereby realizing the adjustment of the suction pipe in the y direction. When facing some porcelain blanks with larger diameters, the adsorption position of the suction pipe 4 can be adjusted accordingly to improve applicability.

[0034] The preferred embodiment, combined with Figure 3 As shown, the pipeline adopts a telescopic tube, which can be pulled to extend when the negative pressure part is displaced, thereby maintaining the communication between the negative pressure part 3 and the displacement part 2.

[0035] The preferred embodiment, combined with Figure 4 As shown, a slide rail 203 is provided at the slider 202, and a slidingly connected brake member 5 is provided inside the slide rail 203. The brake member 5 can slide in the up and down directions along the slide rail 203, and when sliding downward, it can come into contact with the outer circle of the guide column 301. The friction force generated by the contact is used to position the guide column 301, thereby avoiding the staff accidentally touching the suction pipe 4 during use, causing the suction pipe 4 to collide with the porcelain blank, thereby ensuring safe use.

[0036] The preferred embodiment, combined with Figure 5 As shown, the brake member 5 includes a slide 501 and a gasket 502; the slide 501 is slidably connected to the slide rail 203; the gasket 502 is installed on the slide 501, and the two can be bonded together. By pushing the slide 501 downward, the gasket 502 contacts the guide column 301 to generate friction resistance, thereby achieving positioning.

[0037] The preferred embodiment, combined with Figure 5 As shown, the gasket 502 is crescent-shaped and made of rubber material. By utilizing the elastic characteristics of the rubber material, when the slide 501 is pushed downward, the gasket 502 contacts the guide column 301 and is squeezed and deformed as the force continues to be applied, thereby achieving a braking effect. At the same time, the crescent-shaped structural design facilitates the contact between the gasket 502 and the guide column 301.

[0038] The preferred embodiment, combined with Figure 4 As shown, a limiting plate 204 is provided at the bottom of the slide rail 203 to position the slide seat 501 and prevent it from sliding off the bottom.

[0039] The preferred embodiment, combined with Figure 4 As shown, a cylindrical handle is welded on the top of the slide 501, which is convenient for the staff to press it with their hands, or pull the slide 501 upward to facilitate operation. Specific implementation method 2

[0041] Combine Figure 3 As shown, when the negative pressure part 3 does not need to be adjusted in the y direction, a metal tube can be used to connect the negative pressure part 3 and the displacement part 2 to form an integrated structure.

[0042] When trimming the bottle body of the porcelain blank, a PLC can be installed to connect with the control motor to ensure that the control motor drives the suction pipe 4 to rise or fall at a uniform speed, thereby realizing the dust adsorption operation when polishing the bottle body.

[0043] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
