Description

Technical Field

[0001] The utility model belongs to the technical field of coating production, and more specifically relates to a powder coating production sampling and detection device. Background Art

[0002] Powder coatings are synthetic resin coatings in a solid powder form, composed of solid resins, pigments, fillers, and additives. Unlike conventional solvent-based and water-based coatings, their dispersion medium is air, not solvent or water. They are characterized by zero solvent contamination, 100% film formation, and low energy consumption. Powder coatings must be tested before use to confirm their functional effectiveness and the presence of hazardous substances.

[0003] At present, the Chinese utility model patent with announcement number CN215931410U discloses a detection sampling device for a paint production line, including a material box, a stirring mechanism is installed on the top of the material box, and a placement mechanism is provided under the material box. A spraying mechanism is provided on the outer wall of one side of the material box, wherein the connecting pipe in the spraying mechanism is always in an open state. When the paint is stirred, some paint will enter the connecting pipe. When the paint needs to be tested, the paint entering the connecting pipe will affect the detection of the sampled paint, which needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a powder coating production sampling and detection device, which has the advantage of improving the quality of coating sampling.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A powder coating production sampling and detection device includes a mixing box, wherein the side walls of the mixing box are respectively provided with an inlet and an outlet, a stirring mechanism is provided on the top of the mixing box, and a sampling device is installed on the side wall of the mixing box away from the inlet and the outlet. The sampling device includes: a material taking barrel installed on the side wall of the mixing box through a mounting plate, one end of the material taking barrel extends into the mixing box, a sampling port is opened at the end of the material taking barrel located in the mixing box, an air intake pipe and a sample discharge pipe are installed on the material taking barrel, a first cylinder is installed at the end of the air intake pipe, a push block is installed at the output end of the first cylinder, a sealing cover is installed on the sample discharge pipe, and a sealing component for sealing the sampling port is slidably installed in the material taking barrel.

[0007] The advantages of this solution are at least as follows: when it is necessary to sample the paint, the sealing assembly is first activated to release the seal on the sampling port. At this time, a portion of the paint will enter the material barrel through the sampling port. When the sampling port of the material barrel is completely blocked by the paint, the first cylinder is then activated to drive the push block to move upward in the suction pipe. At this time, negative pressure is generated in the material barrel, and the paint blocked in the sampling port is sucked into the material barrel, allowing the paint to continuously enter the material barrel. After sampling is completed, the sealing assembly is activated again to seal the paint, and the paint in the material barrel is released through the sampling pipe for testing. When it is no longer necessary to sample the paint, the sampling port is sealed by the sealing assembly, avoiding the phenomenon in the prior art where part of the paint enters the material barrel during stirring.

[0008] The utility model is further configured as follows: a support plate is installed on the side wall of the mounting plate, and the sealing assembly includes: a second cylinder installed on the support plate, a sliding rod slidably installed in the material barrel and a sealing plate fixed at one end of the sliding rod, and the end of the sliding rod away from the sealing plate is fixedly installed at the output end of the second cylinder, and the sealing plate matches the sampling port.

[0009] The advantage of this solution is at least that the sampling port is sealed by a sealing plate, which prevents the paint from entering the sampling tube when sampling is not required, thereby improving the sampling quality of the sampling device and improving the accuracy of detection.

[0010] The utility model is further configured as follows: a guide block is installed on the side wall of the sealing plate, and the guide block is conical.

[0011] The advantage of this solution is at least that the conical guide block can reduce the contact area between the guide block and the paint in the mixing box, thereby reducing the resistance of the paint when the guide block moves, making it easier to open the sealing plate.

[0012] The utility model is further configured as follows: a sealing ring is provided at the connection where the material taking barrel and the sliding rod are slidably connected.

[0013] The advantage of this solution is at least that the sealing ring can improve the sealing performance in the material taking barrel, thereby preventing air leakage and the inability to properly suck the paint blocking the sampling port into the material taking barrel.

[0014] The utility model is further configured as follows: a guide plate is installed at the opening of the sampling port.

[0015] The advantage of this solution is at least that the guide plate can guide the paint into the material dispensing barrel, making it easier for the paint to enter the material dispensing barrel.

[0016] The utility model is further configured as follows: the sealing cover is composed of a filter cartridge and a sealing cover which are connected to the sample tube through threads; a filter screen is installed in the filter cartridge, and the sealing cover is connected to the filter cartridge through threads.

[0017] The advantage of this solution is at least that: by providing the filter cartridge and the filter screen, impurities in the paint can be filtered out, thereby improving the quality of the paint taken out of the mixing box and thus improving the accuracy of detection.

[0018] The utility model is further configured as follows: a reinforcement rod is provided between the installation plate and the support plate.

[0019] The advantage of this solution is at least that the reinforcement rod can improve the connection strength between the mounting plate and the support plate, thereby preventing the support plate from being broken due to external impact during long-term use.

[0020] In summary, the present invention has at least the following advantages:

[0021] 1. By setting up a sampling device and a sealing component, when it is necessary to sample the paint, first start the sealing component to release the seal on the sampling port. At this time, a part of the paint will enter the material barrel through the sampling port. When the sampling port of the material barrel is completely blocked by the paint, then start the first cylinder, which drives the push block to move upward in the suction pipe. At this time, negative pressure will be generated in the material barrel, and the paint blocked in the sampling port will be sucked into the material barrel, and the paint will continue to enter the material barrel. After the sampling is completed, start the sealing component again to seal the paint, and release the paint in the material barrel through the sampling tube for testing. When it is not necessary to sample the paint, the sampling port is sealed by the sealing component, avoiding the phenomenon in the prior art that part of the paint will enter the material barrel during stirring.

[0022] 2. By setting a conical guide block, the contact area between the guide block and the paint in the mixing box can be reduced, thereby reducing the resistance of the paint when the guide block moves, making it easier to open the sealing plate. The setting of the sealing ring can improve the sealing inside the material barrel, thereby avoiding air leakage and the inability to suck the paint blocked in the sampling port into the material barrel. The setting of the guide plate can guide the paint into the material barrel, making it easier for the paint to enter the material barrel;

[0023] 3. By setting up the filter cartridge and filter net, impurities in the paint can be filtered out, and the quality of the paint taken out from the mixing box can be improved, thereby improving the accuracy of detection. The setting of the reinforcement rod can improve the connection strength between the mounting plate and the support plate, avoiding the support plate from being broken by external force due to long-term use.

DETAILED DESCRIPTION

[0031] The present invention will be described in further detail below with reference to the accompanying drawings.

[0032] A powder coating production sampling and detection device, such as Figure 1 、 Figure 2 As shown, it includes a mixing box 1, the side walls of the mixing box 1 are respectively provided with a feed port 2 and a discharge port 3, and a stirring mechanism 4 is provided on the top of the mixing box 1. The stirring mechanism 4 is usually composed of a servo motor, a stirring shaft and a stirring blade. The servo motor is installed on the top or side wall of the mixing box 1, the stirring shaft is rotatably installed in the mixing box 1, and the stirring blade is installed on the stirring shaft. It belongs to the prior art and will not be described in detail here. A sampling device 5 is installed on the side wall of the mixing box 1 away from the feed port 2 and the discharge port 3;

[0033] like Figure 3 As shown (refer to Figure 5), the sampling device 5 includes: a material taking barrel 501 mounted on the side wall of the mixing box 1 via a mounting plate, one end of the material taking barrel 501 extending into the mixing box 1, and a sampling port 8 being provided at the end of the material taking barrel 501 located in the mixing box 1. It is worth mentioning that a guide plate 12 is installed at the opening of the sampling port 8, which can guide the paint entering the material taking barrel 501, making it easier for the paint to enter the material taking barrel 501. An air intake pipe 502 and a sample tube 503 are installed on the material taking barrel 501, a first air cylinder 6 is installed at the end of the air intake pipe 502, a push block 7 is installed at the output end of the first cylinder 6, a sealing cover 504 is installed on the sample tube 503, and a sealing assembly 9 for sealing the sampling port 8 is slidably installed in the material taking barrel 501.

[0034] A support plate 10 is mounted on the side wall of the mounting plate, and a reinforcement rod 14 is provided between the mounting plate and the support plate 10. The reinforcement rod 14 improves the connection strength between the mounting plate and the support plate 10, and prevents the support plate 10 from being broken by external impact due to long-term use.

[0035] like Figure 4 As shown, in order to facilitate the sealing and opening of the sampling port 8, in some embodiments, the sealing assembly 9 includes: a second cylinder 901 mounted on the support plate 10, a sliding rod 902 slidably mounted in the material taking barrel 501, and a sealing plate 903 fixed to one end of the sliding rod 902, and the end of the sliding rod 902 away from the sealing plate 903 is fixedly mounted on the output end of the second cylinder 901, and the sealing plate 903 matches the sampling port 8. Furthermore, a sealing ring 13 is provided at the connection where the material taking barrel 501 and the sliding rod 902 are slidably connected. The sealing ring 13 can improve the sealing inside the material taking barrel 501, thereby preventing air leakage and the inability to well suck the paint blocking the sampling port 8 into the material taking barrel 501.

[0036] It is worth mentioning that, in order to facilitate the opening of the sealing plate 903 , a guide block 11 is installed on the side wall of the sealing plate 903 , and the guide block 11 is conical.

[0037] like Figure 6 As shown, the sealing cover 504 consists of a filter cartridge 5041 and a sealing cover 5043 which are threadedly connected to the sample tube 503. A filter screen 5042 is installed in the filter cartridge 5041, and the sealing cover 5043 is threadedly connected to the filter barrel. The filter screen 5042 can filter out impurities in the paint, improve the quality of the paint taken out from the mixing box 1, and thus improve the accuracy of the detection.

[0038] The working process and beneficial effects of the utility model are as follows:

[0039] When it is necessary to sample the paint, first start the second cylinder 901, and the second cylinder 901 drives the sliding rod 902 and the sealing plate 903 to move, so that the sealing plate 903 releases the seal on the sampling port 8. At this time, a part of the paint will enter the material barrel 501 through the sampling port 8. When the sampling port 8 of the material barrel 501 is completely blocked by the paint, then start the first cylinder 6 again, and the first cylinder 6 drives the push block 7 to move upward in the suction pipe 502. At this time, negative pressure will be generated in the material barrel 501, and the paint blocked in the sampling port 8 will be sucked into the material barrel 501, and the paint will continue to enter the material barrel 501. After sampling is completed, start the sealing assembly 9 again to seal the paint, and release the paint in the material barrel 501 through the sampling tube 503, and filter it through the filter mesh 5042 in the filter barrel 5041, and then take it for testing.

[0040] When there is no need to sample the paint, the sampling port 8 is sealed by the sealing component 9, thereby avoiding the phenomenon in the prior art that part of the paint enters the material taking barrel 501 during stirring.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
