[0002] The paint additive, also known as the paint auxiliary material, is a functional additive specially designed for the paint formula, which can improve the paint performance and promote the paint film formation. In the paint production process, the paint additive accounts for a small proportion in the overall additive amount but has a great effect, and the slight error in the addition amount will have a great impact on the quality stability of the product.
[0003] Currently, the addition process of the paint additive generally relies on the manual operation of the employees, who use containers to weigh and transfer the additive. To ensure the accurate addition, the process needs to be frequently weighed and added for multiple times, which not only leads to the repeated opening and closing of the cover of the additive storage tank by the employees, increasing the complexity of the operation, but also makes the additive easily contaminated or lost in the frequent operation, thereby adversely affecting the quality of the final product.

[0022] The embodiments of the present utility model will be described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and cannot be understood as a limitation of the present utility model.
[0023] The powder coating additive adding device of the embodiments of the present utility model will be described below in conjunction with the drawings.
[0024] As Figures 1-3 shown, the powder coating additive adding device of the embodiments of the present utility model can include a storage tank 10 and a quantitative adding mechanism (not shown in the figure).
[0025] The quantitative adding mechanism includes a transfer drum 20 and a rotating part 30, wherein the top surface of the transfer drum 20 is provided with an inlet 21 and an air jet 22, and the bottom surface is provided with an outlet 23, wherein the inlet 21 and the outlet 23 are respectively arranged on both sides of the transfer drum 20, the air jet 22 is arranged directly above the outlet 23, and the inlet 21 is in communication with the storage tank 10.
[0026] The rotating part 30 is rotatably arranged in the interior of the transfer drum 20, the rotating shaft 31 is movably connected with the transfer drum 20, and one end of the rotating shaft 31 penetrates through the transfer drum 20 and is connected with the control part 50.
[0027] The rotating member 30 comprises a rotating shaft 31, a surrounding plate 32, a plurality of bottom plates 33 and partition plates 34, wherein the rotating shaft 31 and the surrounding plate 32 are coaxially arranged, the surrounding plate 32 is annular and arranged outside the rotating shaft 31, and the rotating shaft 31 and the surrounding plate 32 are connected through a plurality of circumferentially distributed partition plates 34. The top surface and the bottom surface of the surrounding plate 32 respectively slide against the inner cavity of the middle transfer cylinder 20, and the plurality of partition plates 34 are circumferentially and uniformly arranged. The bottom plates 33 and the partition plates 34 correspond to each other, and each bottom plate 33 is arranged at the bottom of the corresponding adjacent two partition plates 34, the bottom plate 33 abuts against the inner cavity bottom wall of the middle transfer cylinder 20, and one end of the bottom plate 33 is rotationally connected with one of the partition plates 34. The inner cavity top wall of the middle transfer cylinder 20, the rotating shaft 31, the surrounding plate 32, the bottom plate 33 and the adjacent two partition plates 34 form a conveying chamber 40.
[0028] It should be noted that the control member 50 described in this embodiment can be controlled by a motor or other mechanical control means, or can be manually operated by a handle. The rotation of the rotating shaft 31 can be easily controlled by the control member 50.
[0029] In addition, the rotating direction of the rotating shaft 31 is limited to only one side of the bottom plate 33 connected with the partition plate 34, so that when the bottom plate 33 completely covers the outlet 23, the bottom plate 33 can be smoothly separated from the inner cavity of the middle transfer cylinder 20 and rotated around the end connected with the partition plate 34, so that the additives in the conveying chamber 40 can be transferred to the outlet 23 without obstacles.
[0030] It should be noted that the jet port 22 described in this embodiment is designed to be externally connected, and can be connected with an external jet device such as a blower. After starting the external jet device, the jet port 22 will apply a pushing force to the corresponding conveying chamber 40 towards the outlet 23, helping the additives in the conveying chamber 40 to be completely discharged into the container to be added, achieving precise addition.
[0031] As a possible case, the adjacent two conveying chambers 40 are respectively connected with the inlet 21 and the outlet 23, which reduces the moving distance of the additives from the inlet 21 to the outlet 23, maximally reduces the loss in the conveying process, and is beneficial to the accurate metering and addition of the additives.
[0032] Specifically, in order to achieve precise quantitative addition of the additives, the operator first needs to connect the jet port 22 with the external jet device, and connect the outlet 23 with the target container through the conduit. Then, the rotating shaft 31 is started to rotate by the control member 50, and the plurality of conveying chambers 40 pass through the inlet 21 and the outlet 23 in turn. In this process, the additives in the storage tank 10 fall into the corresponding conveying chamber 40 from the inlet 21, and continue to move towards the outlet 23 when the conveying chamber 40 is fully loaded. The design of the middle transfer cylinder 20 can effectively remove the excess additives, ensuring the accuracy of the amount of additives in the conveying chamber 40.
[0033] When the conveying chamber 40 is completely rotated to the position of the outlet 23, the bottom plate 33 is separated from the bottom wall of the inner cavity of the transfer cylinder 20, and the bottom plate 33 loses support and automatically turns over into the outlet 23 with the end connected with the partition plate 34 as the axis. At this time, the additives in the conveying chamber 40 are smoothly transferred to the outlet 23. At the same time, the operator controls the external air injection equipment to blow air to the outlet 23 through the air injection port 22, further promoting the transfer of the additives. Finally, the additives accurately enter the target container through the conduit, and the accurate addition work is completed.
[0034] In an embodiment of the present application, as shown in Figure 1 The horizontally arranged transfer cylinder 20 is relatively flat inside the conveying chamber 40, which is more conducive to uniform distribution and helps the quantitative addition of additives.
[0035] In summary, the powder coating additive adding device in the embodiment of the present application can select the corresponding number of conveying chambers as needed through the quantitative adding mechanism to accurately transfer the additives from the storage tank. During this process, the weighing step of the additives is stably performed in the transfer cylinder, effectively ensuring the stability of the additives. At the same time, combined with the ingenious design of the air injection port and the bottom plate, the accurate control of the additives during the transfer process is ensured, and thus the accurate addition of the additives is realized.
