Description

Technical Field

[0001] The utility model relates to the field of paint mixing equipment, in particular to a splash-proof paint closed mixing device. Background Art

[0002] When using current paint, multiple paints need to be mixed before painting. Current paint mixing generally involves pouring multiple paints into a cylinder, and then extending a stirring mechanism into the cylinder to stir the paint. Since the stirring mechanism is a high-speed stirring mechanism, the paint will splash out of the cylinder during stirring (both liquid paint and powder paint will splash out). When mixing paint in a closed space, paint splashing can be avoided. However, the closed space needs to be opened each time the material is fed and unloaded, which makes the operation of the staff cumbersome. At the same time, the closed space cannot be continuously stirred and mixed, so the mixing efficiency is reduced. Summary of the invention

DETAILED DESCRIPTION

[0018] Now in conjunction with the accompanying drawings, the utility model is further explained.

[0019] like Figure 1-5 As shown, a splash-proof closed paint mixing device comprises a mixing barrel 1, a low-speed mixing chamber 9, a high-speed mixing chamber 10 and a stirring mechanism 11. The mixing barrel 1 is a circular barrel, and a partition 2 is arranged in the mixing barrel 1 by welding. The top surface of the partition 2 is a conical surface (i.e., a funnel) that tilts downward in the middle. The mixing barrel 1 is divided into an upper and lower layer by the partition 2, and the upper and lower layers of the mixing barrel 1 are the low-speed mixing chamber 9 and the high-speed mixing chamber 10 respectively. Since the partition 2 is a conical surface, it is convenient to transfer the material in the low-speed mixing chamber 9 to the high-speed mixing chamber 10, and a stirring mechanism 11 is arranged in each mixing chamber. There is a stirring mechanism 11 with different stirring speeds, and a circular notch 3 is opened at the center of the partition 2. The mixed material in the low-speed mixing bin 9 enters the high-speed mixing bin 10 through the notch 3. A blocking block 4 is inserted into the notch 3 and is lifted and lowered with the upper stirring mechanism 11. The notch 3 is blocked by the blocking block 4. When the mixed material in the low-speed mixing bin 9 needs to enter the high-speed mixing bin 10, the blocking block 4 can be lowered to achieve the effect. A negative pressure suction pipe 15 is connected to the bottom of the high-speed mixing bin 10, and the mixed powder and liquid materials in the high-speed mixing bin 10 are adsorbed by the negative pressure suction pipe 15.

[0020] The stirring mechanism 11 includes a stirring motor, a stirring shaft 13 and stirring blades 14, wherein the output shaft of the stirring motor is connected to the stirring shaft 13 by welding, and a plurality of stirring blades 14 are installed on the outer wall of the stirring shaft 13 by welding, and the shells of the two stirring motors are respectively installed on the top and bottom of the mixing bin by bolt fastening, the low-speed stirring motor 12 is located at the top of the mixing bin, and the high-speed stirring motor 12.1 is located at the bottom of the mixing bin; a blocking block 4 is installed in the high-speed mixing bin 10, and the blocking block 4 extends into the notch 3 of the partition 2, and the blocking block 4 blocks the notch 3, thereby blocking the powder In order to facilitate the circulation of liquid materials, the block 4 is slidably connected to the inner wall of the high-speed mixing bin 10, and the inner wall of the block 4 fits with the inner wall of the gap 3. A linkage assembly 18 is arranged at the top of the rotating shaft in the high-speed mixing bin 10 and the bottom of the block 4. The block 4 closes the gap 3 when the rotating shaft rotates through the linkage assembly 18. When the rotating shaft in the high-speed mixing bin 10 rotates at high speed, the linkage assembly 18 lifts the block 4 upward so that the gap is closed. When the high-speed rotating shaft stops working, the linkage assembly 18 drives the block to descend, so that the material in the low-speed mixing bin 9 enters the high-speed mixing bin 10.

[0021] Connecting rods 5 extending outward are fixed on both sides of the block 4 by welding, a lifting rod 6 is fixed on the bottom of the other end of each connecting rod 5 by welding, and a sleeve 7 sleeved on the lifting rod 6 is fixed on the inner wall of the high-speed mixing bin 10 by welding, so that the vertical lifting of the block 4 is realized.

[0022] The linkage assembly 18 includes a swing rod 19, a ball sliding seat 20, a support rod 21 and a lifting plate 22, wherein the lifting plate 22 is arranged at the top of the rotating shaft in the high-speed mixing chamber 10, and a telescopic rod 23 is arranged between the bottom of the lifting plate 22 and the top of the rotating shaft. The top of the telescopic rod 23 is welded to the lifting plate 22, and a deep groove extending downward is opened at the top of the rotating shaft. The telescopic rod 23 is inserted into the deep groove for lifting and lowering, so that the lifting and lowering of the lifting plate is realized, so that the lifting plate 22 rotates and rises and falls synchronously with the rotating shaft, and a plurality of swing rods 19 distributed in a ring array are hinged on the outer wall of the rotating shaft, and a counterweight block is welded at the end of each swing rod 19. The swing rod 19 is hinged with a support rod 21, and the other end of the support rod 21 is hinged on the lifting plate 22. A ball sliding seat 20 is fixed to the bottom of the block 4 by welding. When the lifting plate 22 is lifted, the top of the lifting plate 22 contacts the bottom of the ball sliding seat 20, so that the block 4 is lifted up; when working, the rotating shaft in the high-speed mixing bin 10 rotates at a high speed, and the swing rod 19 swings to a horizontal level under the action of centrifugal force, and the support rod 21 goes onto the lifting plate 22, so that the block is pushed upward, and when the rotating shaft stops rotating, the swing rod 19 swings down under the action of its own gravity, so that the block 4 drops and the gap 3 opens.

[0023] A scraper 8 in contact with the top of the partition 2 is fixedly installed at the bottom of the rotating shaft in the low-speed mixing chamber 9 by welding. Multiple scrapers 8 are arranged obliquely. When the rotating shaft rotates, the scraper 8 scrapes the paint material around the partition 2 toward the middle.

[0024] One end of the negative pressure suction pipe 15 is connected to and communicated with a storage tank 16 by welding, and a negative pressure pump 17 is connected to the top of the storage pipe through a pipeline.
