Description

Technical Field

[0001] This utility model relates to the field of coating production technology, specifically to a liquid additive feeding device for coating production. Background Technology

[0002] Paint is a material applied to the surface of an object to be protected or decorated, forming a continuous film that adheres firmly to the object. It is usually a viscous liquid made of resin, oil, or emulsion as the main component, with or without pigments and fillers, and with appropriate additives, and formulated with organic solvents or water. Additives include defoamers, leveling agents, and some special functional additives, such as substrate wetting agents. These additives generally do not form a film and are added in small amounts, but they play a significant role in the process of film formation and durability of the base material. Compared to defoamers and leveling agents, they have weaker adhesion and are mainly used to improve the performance of the paint.

[0003] CN222829565U discloses a liquid additive feeding device for paint production, including an additive tank, a discharge pipe, a ball valve, a nozzle, and a transparent pipe. The additive tank includes an inlet and an outlet, with the outlet connected to the discharge pipe. A ball valve is installed on the side of the discharge pipe near the outlet, and the outlet end of the ball valve is connected to the nozzle via a pipe. The nozzle is an inverted funnel shape, including an inlet and an outlet, with a circular perforated plate at the outlet. The outlet of the nozzle is connected to the transparent pipe, and the outlet of the transparent pipe is connected to the inlet of a mixing tank. This feeding device has a simple structure. A nozzle is installed at the outlet port of the feeding device, and the outlet end of the perforated plate of the nozzle is connected to the transparent pipe, allowing direct observation of the liquid additive's discharge speed. The ball valve can be adjusted according to the observed speed to achieve the desired "slow" feeding effect.

[0004] While the existing technology CN222829565U has many advantages in use, it still has the following problems: the uniformity of additive feeding is not perfect. When the additive enters the tank, it can only fall into the main material inside the tank at a single point, resulting in poor initial uniformity of the additive and the main material. Since the additive is in an agglomerated state after falling onto the surface of the main material, it will affect the subsequent stirring efficiency. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a liquid additive feeding device for coating production.

[0006] The technical solution adopted by this utility model to solve its technical problem is a liquid additive feeding device for paint production, including a tank, a cover plate and a sleeve. A coaxial differential is installed inside the tank. The cover plate is screwed to the outer wall of the upper end of the tank. A drive shaft is rotatably installed inside the cover plate. A sleeve is installed on the outer side of the drive shaft. A flow guide is welded to the outer wall of the sleeve. Fixed blocks distributed in a circular array are welded on both sides of the outer wall of the drive shaft. Guide rods are screwed to the outer side of the fixed blocks. Guide blocks distributed in a circular array are welded to the inner wall of the sleeve.

[0007] By adopting the above technical solution, the cover plate ensures the relative sealing of the mixing space inside the tank, while the drive shaft can be driven to rotate by the motor used at the upper end of the cover plate. After the rotation speed of the drive shaft is increased by the coaxial differential, the coating inside the tank is stirred and mixed through the stirring shaft. The additives put into the tank through the feed pipe first enter the inside of the guide hood. As the drive shaft rotates, it can change the position of the discharge port of the guide hood, so that the additives inside the guide hood can be evenly distributed in different parts of the main material inside the tank, avoiding the concentrated position of the additives falling down and avoiding the gradient difference of the additives diffusing from a single point to the surrounding areas, thereby improving the mixing uniformity and mixing efficiency of the additives and the main material.

[0008] Specifically, fixed arms are welded to both sides of the inner wall of the tank, and the ends of the fixed arms are screwed to the coaxial differential. The output end of the coaxial differential is connected to the stirring shaft by a pin.

[0009] By adopting the above technical solution, the fixed arm fixes the coaxial differential to the inner wall of the tank, ensuring that the coaxial differential is in a stable working position inside the tank. The coaxial differential is located at the upper end of the material level inside the tank, and does not come into contact with the coating inside the tank. However, the coaxial differential can drive the stirring shaft to rotate after being driven by the drive shaft, and the stirring shaft can stir and mix the coating inside the tank.

[0010] Specifically, the lower outer wall of the flow guide is welded with second arc-shaped protrusions on both sides, and a fixing ring is screwed to one side of the inner wall of the tank. The upper end of the fixing ring is welded with a first arc-shaped protrusion distributed in a circular array, and the first arc-shaped protrusions and the second arc-shaped protrusions are distributed in an alternating pattern.

[0011] By adopting the above technical solution, when the drive shaft rotates, it drives the guide block, sleeve and flow guide to rotate synchronously. Since the first arc-shaped protrusion and the second arc-shaped protrusion are staggered, when the first arc-shaped protrusion and the second arc-shaped protrusion come into contact, the second arc-shaped protrusion and the flow guide will be driven to move upward. Through the multi-point first arc-shaped protrusion, the flow guide can be driven to be in a vibrating state during rotation, which helps the additives inside the flow guide to be discharged as a whole through the discharge port, ensuring the integrity of the additive discharge.

[0012] Specifically, a feed pipe is welded to one side of the upper outer wall of the cover plate, the inner wall of the flow guide is designed in a conical shape, and a discharge port is opened on one side of the lower end of the flow guide, the discharge port being located at the lower end of the feed pipe.

[0013] By adopting the above technical solution, the liquid additives enter the conical guide shroud directly through the feed pipe, and flow to the discharge port by the guiding effect of the inner wall of the cone. The circumferentially rotating guide shroud can adjust the falling position of the additives.

[0014] Specifically, the guide block has a through hole inside, and the guide block is slidably installed on the outside of the guide rod through the through hole.

[0015] By adopting the above technical solution, the guide block slides along the guide rod, which restricts the relative rotational freedom between the sleeve and the drive shaft, ensuring that the two can only move relative to each other along the axial direction.

[0016] Specifically, the lower end of the drive shaft is provided with a diamond-shaped groove adapted to the input end of the coaxial differential, and the output end of the coaxial differential is located inside the diamond-shaped groove.

[0017] By adopting the above technical solution, the shape of the diamond-shaped groove is matched with that of the differential input end, ensuring that the two are tightly connected. Thus, the drive shaft can drive the coaxial differential, and the coaxial differential can increase the speed and transmit it to the stirring shaft.

[0018] Specifically, support springs are sleeved on both sides of the guide rod, and the two support springs are distributed on the upper and lower sides of the guide block. The guide block is elastically connected to the fixed block through the support springs.

[0019] By adopting the above technical solution, the elastic force of the support spring can support the guide block, ensuring the relative position stability of the sleeve outside the drive shaft. After the guide shield comes into contact with the first arc-shaped protrusion and the second arc-shaped protrusion, displacement is allowed, which can cause the guide shield to vibrate.

[0020] The beneficial effects of this utility model are:

[0021] The liquid additive feeding device for coating production described in this utility model can change the position of the discharge port of the guide hood by rotating the drive shaft, so that the additive inside the guide hood can be evenly dispersed in different parts of the main material inside the tank, avoiding the concentrated position of the additive falling down, avoiding the gradient difference of the additive spreading from a single point to the surrounding area, thereby improving the mixing uniformity and mixing efficiency of the additive and the main material.

[0022] The liquid additive feeding device for coating production described in this utility model, when the first arc-shaped protrusion contacts the second arc-shaped protrusion, will drive the second arc-shaped protrusion and the guide shroud to move upward. Through the multi-point first arc-shaped protrusion, the guide shroud can be driven to vibrate during rotation, which helps the additive inside the guide shroud to be discharged as a whole through the discharge port, ensuring the integrity of the additive discharge.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the liquid additive feeding device for paint production of this utility model includes a tank 1, a cover plate 2, and a sleeve 3. A coaxial differential 13 is installed inside the tank 1. The cover plate 2 is screwed to the upper outer wall of the tank 1. A drive shaft 22 is rotatably installed inside the cover plate 2. The sleeve 3 is installed on the outer side of the drive shaft 22. A flow guide shroud 32 is welded to the outer wall of the sleeve 3. Fixed blocks 23 distributed in a circular array are welded to both sides of the outer wall of the drive shaft 22. Guide rods 24 are screwed to the outer side of the fixed blocks 23. Guide blocks 31 distributed in a circular array are welded to the inner wall of the sleeve 3.

[0033] During use, the cover plate 2 ensures the relative sealing of the stirring space inside the tank 1, while the drive shaft 22 can be driven to rotate by the motor used at the upper end of the cover plate 2. After the rotation speed of the drive shaft 22 is increased by the coaxial differential 13, the coating inside the tank 1 is stirred and mixed through the stirring shaft 15. The additives put into the tank 1 through the feed pipe 21 first enter the guide hood 32. As the drive shaft 22 rotates, the position of the discharge port of the guide hood 32 can be changed, so that the additives inside the guide hood 32 can be evenly distributed in different parts of the main material inside the tank 1, avoiding the concentrated position of the additives falling down and avoiding the gradient difference of the additives spreading from a single point to the surrounding area, thereby improving the mixing uniformity and mixing efficiency of the additives and the main material.

[0034] To increase the rotational speed, for example, such as Figure 2 As shown, fixed arms 14 are welded to both sides of the inner wall of the tank 1. The ends of the fixed arms 14 are screwed to the coaxial differential 13. The output end of the coaxial differential 13 is connected to the stirring shaft 15 by a pin.

[0035] During use, the fixed arm 14 fixes the coaxial differential 13 to the inner wall of the tank 1, ensuring that the coaxial differential 13 is in a stable working position inside the tank 1. The coaxial differential 13 is located at the upper end of the material level inside the tank 1, and the coaxial differential 13 does not contact the coating inside the tank 1. However, the coaxial differential 13 can drive the stirring shaft 15 to rotate after being driven by the drive shaft 22, and the stirring shaft 15 can stir and mix the coating inside the tank 1.

[0036] To drive vibration, for example, such as Figure 4 As shown, the lower outer wall of the flow guide 32 is welded with a second arc-shaped protrusion 33 on both sides. The inner wall of the tank 1 is screwed to a fixing ring 11. The upper end of the fixing ring 11 is welded with a first arc-shaped protrusion 12 distributed in a circular array. The first arc-shaped protrusion 12 and the second arc-shaped protrusion 33 are distributed in an alternating manner.

[0037] When in use, the drive shaft 22 rotates, driving the guide block 31, sleeve 3 and flow guide 32 to rotate synchronously. Since the first arc-shaped protrusion 12 and the second arc-shaped protrusion 33 are staggered, when the first arc-shaped protrusion 12 and the second arc-shaped protrusion 33 come into contact, the second arc-shaped protrusion 33 and the flow guide 32 will be driven to move upward. Through the multi-point first arc-shaped protrusion 12, the flow guide 32 can be driven to vibrate during rotation, which helps the additives inside the flow guide 32 to be discharged as a whole through the discharge port, ensuring the integrity of the additive discharge.

[0038] For example, for feeding, such as Figure 2 As shown, a feed pipe 21 is welded to one side of the upper outer wall of the cover plate 2. The inner wall of the flow guide 32 adopts a conical shape design. A discharge port is opened on one side of the lower end of the flow guide 32. The discharge port is located at the lower end of the feed pipe 21.

[0039] In use, the liquid additive enters the conical guide shroud 32 directly through the feed pipe 21, and flows to the discharge port by the guiding effect of the inner wall of the cone. The circumferentially rotating guide shroud 32 can adjust the falling position of the additive.

[0040] For guidance, exemplified, such as Figure 6 As shown, the guide block 31 has a through hole inside, and the guide block 31 is slidably installed on the outside of the guide rod 24 through the through hole.

[0041] During use, the guide block 31 slides along the guide rod 24, which restricts the relative rotational freedom between the sleeve 3 and the drive shaft 22, ensuring that the two can only move relative to each other in the axial direction.

[0042] To adjust the rotation speed, for example, such as Figure 4 As shown, the lower end of the drive shaft 22 is provided with a diamond-shaped groove adapted to the input end of the coaxial differential 13, and the output end of the coaxial differential 13 is located inside the diamond-shaped groove.

[0043] When in use, the diamond-shaped groove matches the shape of the differential input end, ensuring a tight connection between the two. This allows the drive shaft 22 to drive the coaxial differential 13, and the coaxial differential 13 to increase the rotational speed before transmitting it to the stirring shaft 15.

[0044] To maintain the usage location, for example, such as Figure 5 As shown, support springs 25 are sleeved on both sides of the guide rod 24. The two support springs 25 are distributed on the upper and lower sides of the guide block 31. The guide block 31 is elastically connected to the fixed block 23 through the support springs 25.

[0045] In use, the elastic force of the support spring 25 can support the guide block 31, ensuring the relative position stability of the sleeve 3 outside the drive shaft 22. After the flow guide 32 comes into contact with the first arc-shaped protrusion 12 and the second arc-shaped protrusion 33, displacement is allowed, which can cause the flow guide 32 to vibrate.

[0046] When using this invention, the motor on the upper part of the cover plate 2 is started, and the motor drives the transmission shaft 22 to rotate. The rotational force of the transmission shaft 22 is transmitted to the input end of the coaxial differential 13 through the diamond-shaped groove. After the coaxial differential 13 adjusts and increases the speed, it transmits the power to the stirring shaft 15, so that the stirring shaft 15 begins to stir and mix the main coating material inside the tank 1.

[0047] Liquid additives are fed into the device through the feed pipe 21 at the upper end of the cover plate 2. The additives enter the guide shroud 32 on the outer wall of the sleeve 3 directly through the feed pipe 21. Since the inner wall of the guide shroud 32 is designed in a conical shape, the additives flow to the discharge port at the lower end under the guidance of the conical inner wall.

[0048] When the drive shaft 22 rotates, the fixed block 23 on its outer wall drives the guide rod 24 to rotate synchronously. The guide rod 24, through sliding engagement with the guide block 31 on the inner wall of the sleeve 3, drives the sleeve 3 and the flow guide shroud 32 welded to the outer wall of the sleeve 3 to rotate together. As the flow guide shroud 32 rotates, the position of the discharge port at its lower end changes continuously, so that the additives inside the flow guide shroud 32 can be evenly dispersed to different parts of the main material inside the tank 1.

[0049] During the rotation of the flow guide shroud 32, the second arc-shaped protrusion 33 at its lower end continuously contacts the first arc-shaped protrusion 12 on the fixing ring 11 on the inner wall of the tank 1. Since the two are staggered, when they contact, they will drive the flow guide shroud 32 to move upward, while the support springs 25 on the upper and lower sides of the guide block 31 will reset the flow guide shroud 32 under the action of elasticity, so that the flow guide shroud 32 is in a state of continuous vibration during rotation, and the auxiliary additives are completely discharged through the discharge port;

[0050] While the additives are being added, the stirring shaft 15 rotates continuously under the drive of the coaxial differential 13, stirring the main coating material and the added additives inside the tank 1.

[0051] It should be noted that this utility model is a liquid additive feeding device for paint production.
