Description

Technical Field

[0001] This utility model relates to the field of paint production technology, and more specifically, to a stirring device for paint production. Background Technology

[0002] In the paint production process, mixing is a crucial step, directly affecting the uniform mixing of paint components and consequently influencing the quality and performance of the paint. Existing paint mixing devices typically employ fixed mixing structures, such as common impellers. While these structures can achieve mixing during the process, they have some significant drawbacks: after mixing, a certain amount of paint remains on the inner wall of the discharge cylinder, easily leading to resource waste. Therefore, we propose an improvement to this issue, namely a new mixing device for paint production. Utility Model Content

Each of the plurality of first rotating shafts has a scraper connected to its bottom end and a gear connected to its top end. Gears mesh with each of the gears, and multiple fixing members are provided between the gears and the first support frame. The gears are used to cooperate with the gears to drive the first rotating shafts and scrapers to rotate, so as to realize the contact or separation of the scraper with the inner wall of the material cylinder. When the scraper contacts the inner wall of the material cylinder, it is used to clean the residual material on the inner wall of the material cylinder.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] For an example, please refer to... Figures 1-5 A mixing device for paint production includes a barrel 1, a mixing structure 2 inside the barrel 1, and a support member on the barrel 1. The support member is connected to a first support frame 201. A plurality of first rotating shafts 209 are rotatably connected to the first support frame 201 via bearings. The bottom ends of the plurality of first rotating shafts 209 are all connected to scrapers 210, and the top ends of the plurality of first rotating shafts 209 are all connected to gears 212. Gear rings 213 mesh between the plurality of gears 212, and a plurality of fixing members are provided between the gear rings 213 and the first support frame 201. The gear rings 213 are used to cooperate with the gears 212 to drive the first rotating shafts 209 and scrapers 210 to rotate, so as to realize the contact or separation of scrapers 210 with the inner wall of the barrel 1. When the scrapers 210 are in contact with the inner wall of the barrel 1, they are used to clean the residual material on the inner wall of the barrel 1.

[0027] During the mixing process, the scraper 210 is separated from the inner wall of the barrel 1, reducing unnecessary friction and resistance between the scraper 210 and the inner wall of the barrel 1. During the discharge process, the scraper 210 is rotated to contact the inner wall of the barrel 1. The scraping action of the scraper 210 can remove the residue on the inner wall of the barrel 1, thereby reducing paint waste. If the residue on the inner wall of the barrel 1 is not cleaned and existing cleaning equipment (such as a high-pressure spray gun) is used directly for cleaning, the paint mixed with the cleaning solution may not be recyclable, thus causing waste of resources.

[0028] Furthermore, a second rotating shaft is fixedly connected to the bottom of each of the scrapers 210, and a second support frame 211 is rotatably connected between the bottom ends of the second rotating shafts through bearings. The cooperation between the second support frame 211 and the second rotating shafts can reinforce the bottom of the scraper 210.

[0029] Furthermore, the rotational stroke of the gear ring 213 is less than the distance between the two first rotating shafts 209. Figure 2 The displayed state is when the scraper 210 is in contact with the material cylinder 1. When it is necessary to separate the scraper 210 from the material cylinder 1, it is done according to... Figure 2 Rotate the toothed ring 213 counterclockwise as shown.

[0030] Furthermore, the fasteners include a fixing plate 214 fixedly mounted on the toothed ring 213 and several through holes 216 formed on the first support frame 201. A hand-tightening bolt 215 is threaded onto the fixing plate 214. The bottom end of the hand-tightening bolt 215 is inserted into the inner wall of one of the through holes 216. By inserting the hand-tightening bolt 215 into the through hole 216, the toothed ring 213 can be fixed together with the first support frame 201, so that the toothed ring 213 can rotate synchronously with the first support frame 201. That is, the toothed ring 213 and the first support frame 201 are relatively stationary. After the hand-tightening bolt 215 is separated from the through hole 216, the toothed ring 213 can rotate relative to the first support frame 201.

[0031] Furthermore, the support includes a support disk 202 located in the middle of the first support frame 201. Several first support plates 203 are fixedly connected to the outer surface of the support disk 202. The end of the first support plate 203 away from the support disk 202 is fixedly connected to the inner wall of the first support frame 201. A main shaft 204 is fixedly installed on the top of the first support plate 203. A sleeve 205 is sleeved on the outer surface of the main shaft 204 through a bearing. Two second support plates 206 are fixedly connected to the sleeve 205. Both second support plates 206 are fixedly connected to the gear ring 213. The main shaft 204, the support disk 202, and the first support plates 203 cooperate with each other to support the first support frame 201, while the main shaft 204, the sleeve 205, and the second support plates 206 cooperate with each other to support the gear ring 213.

[0032] Furthermore, a support frame 207 is fitted onto the outer surface of the main shaft 204 via a bearing. The support frame 207 is located above the sleeve 205 and is bolted to the material cylinder 1. The support frame 207 and the material cylinder 1 work together to support the main shaft 204. The bolted connection between the support frame 207 and the material cylinder 1 allows the support frame 207 to be disassembled to remove the stirring structure 2 from the material cylinder 1, thus facilitating the cleaning of the stirring structure 2.

[0033] Furthermore, a motor 208 is mounted on the top of the support frame 207. The output shaft of the motor 208 is connected to the main shaft 204, and the motor 208 can drive the main shaft 204 to rotate.

[0034] Furthermore, several support columns 102 are fixedly installed at the bottom of the material cylinder 1, and the support columns 102 are used to support the material cylinder 1.

[0035] Furthermore, the bottom of the material cylinder 1 is cone-shaped, and the lowest point of the bottom of the material cylinder 1 is connected to a discharge valve 101. After the paint in the material cylinder 1 is stirred, it can be discharged through the discharge valve 101.

[0036] In use, the hand-tightening bolt 215 is rotated to separate it from the through hole 216. Then, the gear ring 213 is rotated, which drives the first rotating shaft 209 and the scraper 210 to rotate through the gear 212. This causes the scraper 210 to rotate until it separates from the material cylinder 1 and the hand-tightening bolt 215 is aligned with the through hole 216. Then, the hand-tightening bolt 215 is rotated to insert it into the through hole 216. After the paint raw material is added into the material cylinder 1, the motor 208 drives the main shaft 204 to rotate. The main shaft 204 drives the first support frame 201 and the scraper 210 to rotate through the support plate 202 and the first support plate 203 to stir the paint in the material cylinder 1. After stirring, the paint in the material cylinder 1 is discharged through the discharge valve 101. During the process of discharging the paint, the scraper 210 is rotated to contact the inner wall of the material cylinder 1, and the scraper 210 scrapes off the residual material on the inner wall of the material cylinder 1.
