Description

Technical Field

[0001] This utility model relates to the field of coating processing technology, specifically to a heavy-duty anti-corrosion powder production and processing equipment. Background Technology

[0002] Heavy-duty anti-corrosion powder coatings are high-performance functional powder coatings specifically designed for extremely corrosive environments. They are made from epoxy resin, polyester resin, or fluorocarbon resin as a matrix, and by adding a high proportion of nano-scale metal fillers, flake-like anti-corrosion pigments, and corrosion inhibitors, etc., they are formed into fine powder particles that can effectively resist corrosion from seawater, chemical media, high temperature and high humidity environments. They are widely used for long-term protection in marine engineering equipment, petrochemical storage tanks, bridge steel structures, and new energy battery compartments. The powder coating process requires the mixing of various raw materials.

[0003] Chinese patent CN215917143U discloses a mixing device for environmentally friendly powder coating processing. This mixing device can seal the feed box with a sealing plate during feeding, thereby effectively preventing dust from being generated during feeding, thus effectively avoiding waste and pollution, and also preventing harm to workers.

[0004] The aforementioned device discharges the mixed powder coating through a discharge pipe. The discharge pipe is equipped with a valve. However, due to the design of the discharge pipe, when the raw material is poured into the box, some of the raw material will fall into the discharge pipe. The raw material in the discharge pipe is not subjected to a stirring action. This results in the unmixed raw material in the discharge pipe being discharged together with the mixed coating when the valve is opened, leading to localized unevenness. Furthermore, the mixing efficiency of the aforementioned device is low, thereby reducing production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a heavy-duty anti-corrosion powder production and processing equipment, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A heavy-duty anti-corrosion powder production and processing equipment includes a tank rotatably mounted between two vertical plates via a rotating shaft. A tilting mechanism is provided on the outer surface of one of the vertical plates, driving the tank to rotate. A pipe is mounted on the top of the tank. A first motor is mounted above the pipe via a lifting mechanism, which drives the first motor to move vertically. A connecting shaft is connected to the end of the output shaft of the first motor, and the end of the connecting shaft slides through the pipe. Helical blades are mounted on the outer surface of the connecting shaft, contacting the inner wall of the pipe. A plug is installed at the bottom of the connecting shaft, fitting with the bottom outlet of the pipe. A second motor is mounted at the bottom of the tank, and a stirring shaft is connected to the end of the output shaft of the second motor.

[0008] Therefore, while the second motor drives the stirring shaft, the tilting mechanism rotates the tank back and forth, causing the raw materials to tumble within the tank. This combined action of tumbling and stirring promotes rapid mixing of the materials, significantly improving production efficiency. Furthermore, during the mixing process, the plug can rise and seal the discharge port of the pipe, preventing some raw materials from falling into the pipe and failing to mix, thus avoiding uneven mixing in certain areas.

[0009] Furthermore, the tilting mechanism includes two fixed plates mounted on the outer surface of the upright plate, with a worm gear rotatably mounted between the two fixed plates. A third motor is mounted on the outer surface of one of the fixed plates, and the output shaft of the third motor is connected to the worm gear. A worm wheel is mounted at the end of the rotating shaft, and the worm wheel meshes with the worm gear.

[0010] Furthermore, the lifting mechanism includes an electric push rod mounted on the outer surface of the tube body via a fixed sleeve, a lifting plate being mounted at the end of the telescopic end of the electric push rod, and a first motor being mounted on the upper surface of the lifting plate.

[0011] Furthermore, four guide rods are installed on the top of the tank, and the lifting plate is slidably installed on the outside of the guide rods.

[0012] Furthermore, a top plate is mounted on the top of all four guide rods.

[0013] Furthermore, a material pipe is connected to the outer surface of the tube body, and a hopper is provided at the end of the material pipe.

[0014] Furthermore, a base frame is installed at the bottom of both uprights, and support plates are provided on both sides of the uprights, with the ends of the support plates connected to the upper surface of the base frame.

[0015] Furthermore, both the top of the tank and the bottom of the plug are conical structures.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] 1. In this invention, while the stirring shaft is driven by the second motor, the tank is rotated back and forth by the flipping mechanism, so that the raw materials roll back and forth in the tank. Under the combined action of rolling and stirring, the raw materials can be mixed quickly, which can significantly improve production efficiency.

[0018] 2. This utility model uses a flipping mechanism to drive the tank to flip, and the forward and reverse rotation of the first motor can be used to achieve the purpose of feeding and discharging. When the first motor drives the spiral blade to rotate for feeding, it can also drive the plug to rotate at the same time, so that the raw material falling on the plug is thrown to all sides under the action of centrifugal force, which improves the uniformity of raw material distribution and further enhances the subsequent mixing efficiency. In addition, during the mixing process, the plug can rise and seal the discharge port of the tube, which can prevent some raw material from falling into the tube and not being mixed when the tank flips back and forth, resulting in local unevenness.

[0024] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4This utility model provides a heavy-duty anti-corrosion powder production and processing equipment, including a tank 2 rotatably mounted between two vertical plates 1 via a rotating shaft 201. A tilting mechanism 3 is provided on the outer surface of one of the vertical plates 1, which drives the tank 2 to rotate. A pipe 202 is mounted on the top of the tank 2. A first motor 203 is mounted above the pipe 202 via a lifting mechanism 4, which drives the first motor 203 to move vertically. A connecting shaft 204 is connected to the end of the output shaft of the first motor 203, and the end of the connecting shaft 204 slides through into the pipe 202. A spiral blade 205 is mounted on the outer surface of the connecting shaft 204, and the spiral blade 205 contacts the inner wall of the pipe 202. A plug 206 is installed at the bottom of the connecting shaft 204, and the plug 206 is adapted to the bottom outlet of the pipe 202. A second motor 207 is mounted at the bottom of the tank 2, and a stirring shaft 208 is connected to the end of the output shaft of the second motor 207.

[0026] In use, the lifting mechanism 4 drives the first motor 203 to descend, and separates the plug 206 from the bottom discharge port of the tube 202. Then, the first motor 203 drives the connecting shaft 204 to rotate, and drives the spiral blade 205 and the plug 206 to rotate. The rotation of the spiral blade 205 can convey the raw material downward. When the raw material falls on the rotating plug 206, it is thrown to all sides by centrifugal force, which improves the uniformity of the raw material distribution and enhances the subsequent mixing efficiency.

[0027] After feeding is completed, the lifting mechanism 4 raises the plug 206 to seal the discharge port at the bottom of the tube 202. Then, the second motor 207 is started to drive the stirring shaft 208 to stir the raw materials. The tilting mechanism 3 also causes the tank 2 to tilt back and forth. The combined action of tumbling and stirring promotes rapid mixing of the raw materials, significantly improving production efficiency. Furthermore, because the plug 206 seals the discharge port of the tube 202, it prevents some raw materials from falling into the tube 202 and failing to mix, thus avoiding uneven mixing.

[0028] The tilting mechanism 3 drives the tank 2 to tilt back and forth, which can be divided into 180-degree and 360-degree tilting. A 180-degree tilt involves rotating 180 degrees and then returning to the original trajectory; it is not a continuous 360-degree rotation. Since the maximum rotation angle of the second motor 207 is 180 degrees, it does not affect the wiring connection. A 360-degree tilt involves continuous rotation. The power supply cable for the second motor 207 can pass outward from the axis of the rotating shaft 201 and be connected to the power supply cable through an electric slip ring. Both methods can achieve the purpose of tilting materials, and the appropriate method can be selected according to the actual situation.

[0029] Preferably, the flipping mechanism 3 includes two fixed plates 301 mounted on the outer surface of the upright plate 1, with a worm gear 302 rotatably mounted between the two fixed plates 301. A third motor 303 is mounted on the outer surface of one of the fixed plates 301, and the output shaft of the third motor 303 is connected to the worm gear 302. A worm wheel 304 is mounted at the end of the rotating shaft 201, and the worm wheel 304 meshes with the worm gear 302.

[0030] When the third motor 303 drives the worm 302 to rotate, the worm 302 and the worm wheel 304 mesh with each other, so the tank 2 can be rotated through the rotating shaft 201.

[0031] During the overturning process, the raw materials inside the tank 2 are prone to collapse and generate a large impact force on the tank 2. If this impact force acts on the output shaft of the third motor 303, it can easily damage the output shaft. Therefore, through the transmission method of worm gear 302 and worm wheel 304, due to its self-locking property, the impact force of the tank 2 can be prevented from acting on the output shaft of the third motor 303, thus improving the service life of the third motor 303.

[0032] Preferably, the lifting mechanism 4 includes an electric push rod 402 mounted on the outer surface of the tube body 202 via a fixing sleeve 401, a lifting plate 403 is mounted on the end of the telescopic end of the electric push rod 402, and a first motor 203 is mounted on the upper surface of the lifting plate 403.

[0033] When the electric push rod 402 is activated, its telescopic end drives the lifting plate 403 to rise and fall, thus achieving the purpose of driving the first motor 203 to rise and fall.

[0034] Preferably, four guide rods 5 are installed on the top of the tank body 2, and the lifting plate 403 is slidably installed on the outside of the guide rods 5.

[0035] With the combined limiting effect of multiple guide rods 5 on the lifting plate 403, and the contact between the spiral blade 205 and the inner wall of the tube 202, a certain limiting effect is also achieved. Therefore, the lifting plate 403 can be raised and lowered smoothly, and the extension end of the electric push rod 402 can be prevented from being damaged by lateral force.

[0036] Preferably, a top plate 501 is mounted on the top of the four guide rods 5.

[0037] The four guide rods 5 are connected into a whole by the top plate 501, so that they can share the force and have better stability.

[0038] Preferably, a material pipe 6 is connected to the outer surface of the pipe body 202, and a hopper 601 is provided at the end of the material pipe 6.

[0039] Raw materials are fed into the hopper 601 and can enter the pipe body 202 through the material pipe 6. Under the rotation of the spiral blade 205, the material is fed downward. When the tank body 2 is flipped so that the hopper 601 faces downward, the first motor 203 drives the spiral blade 205 to rotate in the opposite direction, which can transport the paint in the tank body 2 outward, thus achieving the purpose of discharging.

[0040] Preferably, a base frame 101 is installed at the bottom of both upright plates 1, and a support plate 102 is provided on both sides of the upright plates 1, with the end of the support plate 102 connected to the upper surface of the base frame 101.

[0041] This significantly improves the stability of the entire device, reducing the risk of shaking and tilting.

[0042] Preferably, the top of the tank body 2 and the bottom of the plug 206 are both conical structures.

[0043] When the tank 2 is flipped so that the hopper 601 faces downward, the lifting mechanism 4 causes the plug 206 to separate from the discharge port of the pipe 202. The raw material in the tank 2 can enter the pipe 202 and be discharged through the hopper 601. Since the bottom of the plug 206 is a conical structure, it can prevent the paint from adhering to the surface of the plug 206. In addition, the top of the tank 2 is a conical structure, which can promote the rapid discharge of materials and avoid residue.
