Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating production technology, specifically to a coating premixing device for coating production. Background Technology
[0002] Paint is a viscous liquid that is applied to the surface of an object to be protected or decorated, and forms a continuous film that adheres firmly to the object. It is usually based on resin, oil or emulsion, with or without pigments and fillers, and with appropriate additives, and is prepared with organic solvents or water. Paint generally consists of four basic components: film-forming substances (resins, emulsions), pigments (including extender pigments), solvents and additives (auxiliaries). During the production of paint, the prepared raw materials need to be mixed.
[0003] Currently, in the production and processing of coatings, raw materials are put into a mixing tank for mixing. However, because coating raw materials easily absorb moisture from the air, they tend to clump together. During the mixing process, the raw materials are not easily broken up, which results in a long mixing time and poor overall efficiency. To address this, we propose a coating premixing device for coating production. Utility Model Content
[0004] The purpose of this invention is to provide a paint premixing device for paint production, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a paint premixing device for paint production, comprising a mixing tank and a mixing device disposed on the mixing tank, wherein a pretreatment device is disposed inside the mixing tank, and the pretreatment device includes:
[0006] The processing tray is used to initially support the raw materials entering the mixing tank;
[0007] Push plate, the push plate is used to move the material on the top of the processing tray;
[0008] The material discharge hole is used for materials to fall from the processing tray;
[0009] An extrusion mechanism is used to crush materials.
[0010] Preferably, the mixing device includes a motor, which is fixed to the top of the mixing tank. The output shaft of the motor passes through the top of the mixing tank and is rotatably connected to the mixing tank. The output shaft of the motor is fixed to a rotating shaft, and a stirring rod is fixed to the outer wall of the rotating shaft. By driving the rotating shaft to rotate through the motor, the rotating shaft drives the stirring rod to rotate, thereby performing a mixing operation on the raw materials in the mixing tank.
[0011] Preferably, the processing disc is fixed to the inner wall of the mixing tank, the rotating shaft passes through the processing disc and is rotatably connected to the processing disc, the pusher plate is fixed to the outer wall of the rotating shaft, the processing disc has a discharge hole, and the extrusion mechanism is set on the mixing tank and the pusher plate. When the material is put into the mixing tank, it first falls onto the processing disc. When the motor drives the rotating shaft to rotate, the rotating shaft drives the pusher plate to rotate, and the pusher plate can push the material at the top of the processing disc to move. When the material moves to the position of the discharge hole, it can fall off the processing disc. During the movement of the pusher plate, the material can be crushed by the extrusion mechanism, which plays a pre-treatment role and avoids the material from clumping together, which would require a long time for mixing and stirring, thus affecting the processing efficiency.
[0012] Preferably, the extrusion mechanism includes a push rod that passes through the side of the pusher plate away from the rotating shaft. The push rod is slidably connected to the pusher plate. A return spring is fixed on the inner wall of the pusher plate. The end of the return spring away from the pusher plate is fixed to the push rod. A push rod is hinged to the end of the push rod near the rotating shaft. A slide plate is hinged to the end of the push rod away from the push rod. The slide plate is slidably mounted on the inner wall of the pusher plate. A support rod is hinged to the top of the slide plate. A movable frame is hinged to the end of the support rod away from the slide plate. The movable frame passes through the top of the pusher plate and is slidably connected to the pusher plate. Two sets of support rods and movable frames are provided, and the two sets of support rods and movable frames are symmetrically arranged. The moving frames are provided with staggered ejector pins on opposite sides. Several sets of protrusions are fixed on the inner wall of the mixing tank. As the pusher plate rotates, when the pusher plate and the ejector pins come into contact with the protrusions, the ejector pins are retracted into the pusher plate. The ejector pins can then push the sliding plate downwards via the push rod. The sliding plate pulls the two sets of moving frames towards each other via the support rod. The two sets of moving frames can then use the ejector pins on their own to break up the clumps of material between them. When the ejector pins are no longer in contact, they can be reset by the action of the return spring, thereby controlling the reset of the two sets of moving frames and achieving intermittent repeated crushing. This can effectively prevent material clumping from affecting the normal mixing and processing efficiency.
[0013] Preferably, the mixing tank is provided with a feed inlet at the top and a discharge outlet at the bottom. Raw materials are fed in through the feed inlet and the mixed coating is discharged through the discharge outlet.
[0014] Compared with the prior art, the present invention provides a paint premixing device for paint production, which has the following beneficial effects:
[0015] This paint premixing device for paint production, through its mixing and pretreatment devices, allows materials to fall onto a treatment plate when they are fed into the mixing tank. When the motor drives the rotating shaft to rotate, the shaft drives the pusher plate to rotate, which in turn pushes the material at the top of the treatment plate. Once the material reaches the discharge hole, it falls off the treatment plate. During the movement of the pusher plate, the material is crushed by the extrusion mechanism, which serves as a pretreatment to prevent the material from clumping together and thus avoiding the need for prolonged mixing and stirring, which would affect processing efficiency.

Detailed Implementation
[0023] like Figures 1-6 As shown, this utility model provides a technical solution: a paint premixing device for paint production, including a mixing tank 1 and a mixing device 2 installed on the mixing tank 1. The top of the mixing tank 1 is provided with a feed inlet 4 and the bottom of the mixing tank 1 is provided with a discharge outlet 5. Raw materials are fed in through the feed inlet 4 and the mixed paint is discharged through the discharge outlet 5. The mixing tank 1 is provided with a pretreatment device 3, which includes a treatment plate 31, a pusher plate 32, a discharge hole 33, and an extrusion mechanism 34.
[0024] The mixing device 2 includes a motor 21, which is fixed to the top of the mixing tank 1. The output shaft of the motor 21 passes through the top of the mixing tank 1 and is rotatably connected to the mixing tank 1. The output shaft of the motor 21 is fixed to a rotating shaft 22. A stirring rod 23 is fixed to the outer wall of the rotating shaft 22. The rotating shaft 22 is driven to rotate by the motor 21, and the rotating shaft 22 drives the stirring rod 23 to rotate, so that the raw materials in the mixing tank 1 can be mixed and stirred.
[0025] The processing disc 31 is fixed on the inner wall of the mixing tank 1. The rotating shaft 22 passes through the processing disc 31 and is rotatably connected to the processing disc 31. The pusher plate 32 is fixed on the outer wall of the rotating shaft 22. The processing disc 31 has a discharge hole 33. The extrusion mechanism 34 is set on the mixing tank 1 and the pusher plate 32. When the material is put into the mixing tank 1, it first falls on the processing disc 31. When the motor 21 drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the pusher plate 32 to rotate. The pusher plate 32 can push the material at the top of the processing disc 31 to move. When the material moves to the position of the discharge hole 33, it can fall off the processing disc 31. During the movement of the pusher plate 32, the material can be crushed by the extrusion mechanism 34, which plays a pre-treatment role and avoids the material from clumping together, which would require a long time to mix and stir, affecting the processing efficiency.
[0026] The extrusion mechanism 34 includes a push rod 341, which passes through the push plate 32 on the side away from the rotating shaft 22. The push rod 341 is slidably connected to the push plate 32. A return spring 342 is fixed on the inner wall of the push plate 32. The end of the return spring 342 away from the push plate 32 is fixed to the push rod 341. A push rod 343 is hinged to the end of the push rod 341 near the rotating shaft 22. A slide plate 344 is hinged to the end of the push rod 343 away from the push rod 341. The slide plate 344 is slidably mounted on the inner wall of the push plate 32. A support rod 345 is hinged to the top of the slide plate 344. A movable frame 346 is hinged to the end of the support rod 345 away from the slide plate 344. The movable frame 346 passes through the top of the push plate 32 and is slidably connected to the push plate 32. Two sets of support rods 345 and movable frames 346 are provided, and the two sets of support rods 345 and movable frames 346 are symmetrically arranged. The moving frame 346 has staggered ejector pins 347 on one side facing each other. Several sets of protrusions 348 are fixed on the inner wall of the mixing tank 1. As the pusher plate 32 rotates, when the pusher plate 32 and the ejector rod 341 come into contact with the protrusions 348, the ejector rod 341 is pushed into the pusher plate 32. The ejector rod 341 can then push the slide plate 344 downward through the pusher rod 343. The slide plate 344 pulls the two sets of moving frames 346 to move towards each other through the support rod 345. The two sets of moving frames 346 can then break up the clumps of material between them through the ejector pins 347 on their own. When the ejector rod 341 is no longer in contact, it can be reset under the action of the return spring 342, thereby controlling the reset of the two sets of moving frames 346 and playing the role of intermittent repeated crushing. This can effectively prevent the material from clumping together and affecting the normal mixing and processing efficiency.
[0027] In this invention, during use, the coating material is fed into the inlet 4 at the top of the mixing tank 1. The material falls onto the top of the processing plate 31. The motor 21 is started to drive the rotating shaft 22 and the stirring rod 23 to rotate. The rotating shaft 22 drives the pusher plate 32 to rotate, which in turn pushes the material on top of the processing plate 31. As the pusher plate 32 rotates, when the pusher plate 32, along with the push rod 341, comes into contact with the protrusion 348, the push rod 341 is retracted into the pusher plate 32. The push rod 341 can then move through the push rod 348. 43 pushes the slide plate 344 downward, and the slide plate 344 pulls the two sets of moving frames 346 to move towards each other through the support rod 345. The two sets of moving frames 346 can then crush the clumps of material between them through the ejector pins 347 set on them. When the ejector pin 341 is no longer resisted, it can be reset under the action of the return spring 342, thereby controlling the reset of the two sets of moving frames 346 and playing the role of intermittent and repeated crushing. This can effectively prevent the material from clumping together and affecting the normal mixing and processing efficiency.
[0028] Once the material moves to the position of the discharge port 33, it will fall from the processing plate 31 and be mixed by the stirring rod 23. After the mixing is completed, the discharge port 5 can be opened to discharge the mixed coating.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
