Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spraying equipment, in particular to a device for spraying powder on the inner wall of a column. Background Art
[0002] During the powder spraying process on the inner wall of the column, the column will shake because it changes from a moving state to a stationary state, resulting in a thicker coating thickness on the inner wall close to the spray gun and a thin coating thickness in other directions. In order to ensure that the minimum thickness meets the relevant requirements of the specifications, it is necessary to increase the powder spraying amount and reduce the spray gun running speed. This not only wastes powder and increases production costs, but also seriously reduces the production efficiency of the workshop. Utility Model Content
[0003] The purpose of the utility model is to provide a powder spraying device for the inner wall of a column, to increase the powder spraying uniformity of the inner wall of the column, to improve the powder spraying efficiency, and to solve the problems of uneven spraying of the existing columns and low production efficiency raised in the above background technology.
[0004] To achieve the above objectives, the present invention provides the following technical solutions:
[0005] A device for spraying powder on the inner wall of a column comprises a device sleeve. Rollers are arranged on the outside of the device sleeve. Multiple groups of rollers are arranged symmetrically around the central axis of the device sleeve. The device sleeve is sleeved at the connection between the gun head of the spray gun and the delivery pipe.
[0006] A roller mounting device is fixedly arranged on the outer side of the device sleeve.
[0007] The roller is rotatably installed through a pin shaft and a roller installation device.
[0008] Install the threaded holes and bolts on the side wall of the sleeve.
[0009] Compared with the prior art, the beneficial effects of the present invention are:
[0010] The utility model positions and guides the spray head of the spray gun by means of a device sleeve with a roller, so that the spray gun sprays powder evenly on the inner wall of the column, thereby improving the powder spraying efficiency, thereby reducing production costs and improving production efficiency.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0016] like Figure 1-3 As shown, the utility model provides a device for spraying powder on the inner wall of a column, which is installed at the rear end of the gun head of the spray gun, and includes a device sleeve 1. The device sleeve 1 is sleeved at the connection between the gun head of the spray gun and the conveying pipe. A roller 4 is provided on the outside of the device sleeve 1. The roller 4 is provided with multiple groups symmetrically arranged with the center axis of the device sleeve 1. During operation, the roller 4 collides smoothly with the inner wall to ensure that the spray gun is located at the center of the inner wall, thereby ensuring the uniformity of the powder spraying on the inner wall, eliminating the problem of uneven local powder amount, and can increase the running speed of the conveyor chain of the column line and improve production efficiency.
[0017] A roller 4 mounting device 2 is fixedly provided on the outer side of the device sleeve 1. The roller 4 is rotatably mounted with the roller 4 mounting device 2 via a pin shaft 3. The roller 4 is easy to install and disassemble.
[0018] The threaded holes and bolts 5 on the side wall of the installation sleeve 1 are used to fix the installation sleeve 1 to the gun head and delivery pipe of the spray gun. When in use, the gun head and delivery pipe of the spray gun are fixed to the upper and lower parts of the installation sleeve respectively, and the installation is convenient.
[0019] When the utility model is used, the column stops after passing the signal point, and the spray gun with the column inner wall powder spraying device enters the column inner wall for operation. The rollers 4 around the column inner wall powder spraying device will prevent the spray gun from generating rigid friction after hitting the column wall, so that the spray gun is corrected back to the center of the column to complete the spraying action; when the spray gun sprays reciprocatingly up and down, the place where the roller 4 contacts the inner wall can be sprayed, completing the function of checking for leaks and filling gaps.
