Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical spraying processing, in particular to a mechanical spraying processing protective device. Background Art

[0002] Mechanical processing refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. Spraying is a coating method in which a spray gun or a disc atomizer is used to disperse the spray into uniform and fine droplets with the help of pressure or centrifugal force, and then the droplets are applied to the surface of the object. However, most of the existing mechanical spraying processing equipment does not have corresponding protective devices, which leads to the odor generated during the spraying process being easily dissipated, thus affecting the health of the workers. In addition, the spray particles during the spraying process are also easy to float in the air, which will affect the health of the workers after being adsorbed.

[0003] In the prior art, a Chinese patent with a reference number of CN112642636 A discloses a protective device for mechanical spraying processing, including a shell, a mounting frame is fixedly installed on the top of the inner bottom wall of the shell, and clamping devices are arranged on the left and right sides of the mounting frame. The bottom end of the inner top wall of the shell is fixedly connected to a cylinder, and the protruding end of the cylinder is fixedly connected to a spray plate, and the bottom end of the spray plate is fixedly connected to a spray head. The utility model can avoid the occurrence of paint splashing during spraying, and can also absorb the odor generated during the spraying process through the odor absorption device, thereby increasing the protective effect. It has the advantages of good protective effect, etc., and solves the problem that there is no corresponding protective mechanism in the existing spraying process.

[0004] The comparative document provides a mechanical spraying stand with a protective structure, but the above patent requires the workpiece to be fixed before spraying. Since some workpieces need to be sprayed on multiple sides, the workpieces need to be repeatedly disassembled and assembled, and the shell needs to be opened multiple times, which makes the operation cumbersome and the spraying process efficiency low.

[0005] Therefore, a mechanical spraying processing protection device is proposed. Utility Model Content

[0009] Preferably, the interior of the odor adsorption box is filled with adsorption filler.

[0010] Preferably, the spray protection box and the box cover are connected by a mechanical lock.

[0011] Preferably, the screw threads in the first ball screw and the second ball screw have opposite rotation directions.

[0012] Preferably, one end of the first ball screw passes through the spray protection box, and the disc is located outside the spray protection box.

[0013] Preferably, the centers of the two rotating heads are located on a horizontal coaxial line.

[0014] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0015] Through the cooperation of rubber gloves and workpiece clamping components, the spraying surface of the workpiece in the spray protection box can be adjusted without opening the box cover.

The spray pump 8 is located between the paint storage box 7 and the odor absorption box 9, and connecting pipes are provided between the paint storage box 7 and the spray protection box 1 and the spray pump 8.

[0024] It should be noted that, since existing workpieces need to be fixed before spraying, and since some workpieces need to be sprayed on multiple sides, it is necessary to repeatedly disassemble and assemble the workpieces, and the shell needs to be opened multiple times, the operation is cumbersome, and the spraying process efficiency is low. In this embodiment, through the cooperation of the rubber gloves 5 and the workpiece clamping assembly 6, the spraying surface of the workpiece in the spray protection box 1 can be adjusted without opening the box cover 2, and the workpiece can be rotated after clamping, which is convenient for one-time multi-sided spraying. The number of times the workpiece is disassembled and assembled is reduced, which greatly improves the spraying efficiency. The spray protection box 1 does not need to open the box cover 2 during the spraying process, which greatly reduces the leakage of odor during spraying and provides more effective protection for processing personnel.

[0025] Specifically, in this embodiment, the scheme mainly includes a rubber glove 5 and a workpiece clamping assembly 6. Before performing the workpiece spraying operation, the box cover 2 is opened, and the workpiece is placed between the first clamping plate 64 and the second clamping plate 65. The disc 69 is rotated, and the disc 69 drives the first ball screw 62 and the second ball screw 63 to rotate, and the first clamping plate 64 and the second clamping plate 65 move toward each other. The silicone pads 68 on the two rotating heads 67 are respectively in contact with the outer walls on both sides of the workpiece, and the workpiece is clamped. The box cover 2 is closed and locked, and the spray pump 8 extracts the paint in the paint storage box 7 and sprays it into the interior of the spray protection box 1. The paint is sprayed on the outer wall of the workpiece. After completing the single-sided spraying, the rotating cylinder 66 drives the rotating head 67 to rotate through its output end, and the workpiece between the two rotating heads 67 rotates. After adjusting the workpiece angle, spraying is performed again. When it is necessary to spray other surfaces of the workpiece, one hand is worn inside the rubber glove 5, and the workpiece is removed and clamped and fixed again using the rubber glove 5, so as to perform subsequent spraying operations.

[0026] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the interior of the odor adsorption box 9 is filled with adsorption filler.

[0027] In this embodiment, the odor inside the spray protection box 1 can be absorbed by the adsorption filler, thereby preventing the odor from leaking out after the box cover 2 is opened and causing damage to the operator.

[0028] In a further preferred embodiment of the present invention, Figure 4 As shown, the screw threads in the first ball screw 62 and the second ball screw 63 have opposite rotation directions, and one end of the first ball screw 62 passes through the spray protection box 1 , and the disc 69 is located outside the spray protection box 1 .

[0029] In this embodiment, the first clamping plate 64 and the second clamping plate 65 on the first ball screw 62 and the second ball screw 63 can move toward or away from each other by rotating the screw threads in opposite directions, thereby achieving clamping and releasing of the workpiece.

[0030] In a further preferred embodiment of the present invention, Figure 4 As shown, the centers of the two rotating heads 67 are located on a horizontal coaxial line.

[0031] In this embodiment, the workpiece between the two rotating heads 67 can be ensured to rotate stably, thereby adjusting the spraying surface.
