Description

Technical Field

[0001] The utility model relates to the technical field of paint detection, in particular to a sampling device for paint detection. Background Art

[0002] After the existing paint production is completed, it is necessary to sample and test the paint at different depths in the production device to find out whether the produced paint is qualified.

[0003] The existing sampling device for paint detection needs to take the sampling device out of the paint and take out the paint in the sampling device before sampling the next depth point when sampling the paint at a single depth point. In this way, the whole sampling process is very cumbersome and greatly delays the detection efficiency.

[0004] Therefore, it is necessary to provide a sampling device for paint detection, which can sample multiple sampling points at different depths and then remove the sampling device from the paint. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art and provides a sampling device for paint detection, which can sample a plurality of sampling points at different depths and then take the sampling device out of the paint.

[0006] The purpose of the utility model is achieved through the following technical scheme: a sampling device for paint detection, comprising two connected paint inlet cavities and a paint storage cavity, a paint inlet plate matching its cross-section is slidingly sealed in the paint inlet cavity, a paint inlet port is opened on the paint inlet cavity, the paint inlet plate is provided with a first paint inlet channel with openings at both ends, one end of the first paint inlet channel is connected to the paint inlet port through a liquid flow tube, a plurality of storage parts are provided in the paint storage cavity, a second paint inlet channel is provided on the storage part, and a drive component for connecting the first paint inlet channel with the second paint inlet channel is provided in the paint inlet cavity.

[0007] The driving assembly comprises a motor arranged on the inner wall of the paint feeding cavity, a screw rod is arranged at the output end of the motor, and the paint feeding plate and the screw rod are threadably arranged.

[0008] The second paint inlet passage is provided with a one-way valve to prevent the paint in the storage portion from flowing back.

[0009] It also includes a hydraulic pump with two ends connected to the paint inlet and the paint inlet channel.

[0010] The driving assembly is a hydraulic rod arranged on the inner wall of the paint feeding cavity.

[0011] The storage portion is provided with a material taking port, and the material taking port is detachably provided with a sealing cover.

[0012] The beneficial effect of the utility model is that after the utility model enters the paint produced by the production device, it samples points of different depths of the paint, and will not take it out from the paint until all the storage parts are fully stored. Compared with the prior art, there is no need to take out the sampling device after sampling a point of paint, which greatly improves the efficiency of sampling, thereby indirectly improving the efficiency of paint detection.

DETAILED DESCRIPTION

[0016] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0017] It is to be noted that the concepts of directions “left”, “right”, “up”, “down”, “front”, “back”, “inside” and “outside” in the following schemes are all relative directions and will not be listed one by one here.

[0018] A sampling device for paint detection, reference Figure 1 , including a hollow paint feeding cavity 1. A hollow paint storage cavity 2 is arranged on one side of the paint feeding cavity 1. A paint feeding port 11 communicating with the interior of the paint feeding cavity 1 is provided at the center of the upper side.

[0019] refer to Figure 2A paint feeding plate 3 matching its cross section is provided in the paint feeding cavity 1 in an upward and downward sliding and sealing manner. A first paint feeding channel 31 with openings at both ends is provided on the paint feeding plate 3. A hydraulic pump 33 is provided on the paint feeding plate 3. One end of the hydraulic pump 3 is connected to the paint inlet 11 through a bendable flexible liquid flow tube 32, and the other end is connected to the first paint feeding channel 31. A motor 12 is provided in the paint feeding cavity 1. A screw 13 is provided at the output end of the motor 12. The screw 13 is rotatably arranged with the inner wall of the paint feeding cavity 1. Three sliding rods 14 extending up and down are provided in the paint feeding cavity 1. The paint feeding plate 3 and the screw 13 are threadedly rotatably arranged. Three sliding rods 14 are slidably arranged with the paint feeding plate 3. A screw 13 and three sliding rods 14 are respectively provided at four right angles of the paint feeding plate 3.

[0020] Three mutually separated storage parts 21 are arranged in the paint storage chamber 2. A second paint inlet channel 22 is arranged on the storage part 21, which is connected to the inside of the paint inlet chamber 1 and matches the position of the first paint inlet channel 31. A one-way valve 23 is arranged on the second paint inlet channel 22. The one-way valve 23 prevents the paint in the storage part 21 from being discharged from the second paint inlet channel 22. A material taking port 24 is arranged on the storage part 21. A sealing cover 25 is arranged on the material taking port 24 for threaded rotation sealing.

[0021] When it is necessary to sample the paint produced in the production device, the present embodiment is placed in the paint by the lifting device. When it descends to the first sampling point, the motor 12 is started to move the paint feeding plate 3 until the first paint feeding channel 31 is connected to the second paint feeding channel 22 on one of the storage parts 21 that does not store paint, and stops. At this time, the hydraulic pump 33 is started to transport the paint at this point to the storage part 21. Continue to move to the next sampling point and repeat the above operation until each point is sampled. When the sampling is completed, the present embodiment is taken out by the lifting device, the sealing cover 25 is opened, the paint in the storage part 21 is taken out and stored separately, and the entire paint sampling process is completed.
