Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a grinding device for grinding resin coatings. Background Technology

[0002] Currently, grinding equipment is a widely used, high-efficiency grinding device in industries such as coatings, dyes, inks, pesticides, magnetic tapes, papermaking, leather, and chemicals. It boasts advantages such as simple structure, stable start-up, high continuous production efficiency, convenient color change, easy cleaning, and simple operation. Its working principle involves adding a pre-dispersed and wetted liquid-solid mixture to the grinding cylinder, where a rotating agitator generates shearing, impact, and friction effects, refining and homogenizing the material to achieve the desired grinding effect. Grinding equipment for resin coating production is also required in the processing of resin coatings, as follows.

[0003] A search revealed a patent with authorization announcement number CN217221751U, which discloses a grinding device for producing resin coatings with good grinding effect. The device includes a base; an electric push rod is installed on the top left side of the base, and a grinding cylinder is placed on the top right side of the base. A bracket is fixedly installed on the top of the electric push rod, and a motor is installed on the top right side of the bracket. A main stirring rod is driven to the bottom of the motor, and an internal gear ring is installed on the bottom right side of the bracket. This invention uses the retraction of the electric push rod to drive the bracket, main stirring rod, and auxiliary stirring rods into the grinding cylinder. Then, starting the motor drives the main stirring rod and the sun gear to rotate. The sun gear drives the planetary gears on both sides to rotate around the internal gear ring, which in turn drives the two sets of auxiliary stirring rods to rotate around the main stirring rod. Therefore, the cooperation of the main and auxiliary stirring rods greatly improves the grinding efficiency, resulting in faster grinding speed, higher quality, and improved efficiency. Furthermore, the structure is simple, the grinding cylinder is easy to place and remove, and the device is stable and reliable in use.

[0004] However, the grinding equipment used for resin coating production described above still has the following areas for improvement:

[0005] 1. When grinding resin coating raw materials, the grinding cylinder is stationary. Therefore, it only relies on the rotation of the agitator to grind the resin coating raw materials. The shear force generated is generally average, resulting in average grinding effect and grinding efficiency. The structure needs to be improved.

[0006] 2. When grinding raw materials for resin coatings, the grinding cylinder has an open top design. Therefore, when the agitator rotates at high speed to mix and grind the materials, the materials are easily splashed out through the top opening of the grinding cylinder, resulting in unnecessary waste, environmental pollution, and potential harm to nearby workers. Utility Model Content

[0007] This utility model discloses a grinding device for producing resin coatings. It features a rotary material cylinder mechanism, allowing material to be added to the grinding cylinder during operation. Then, a cylinder is activated, extending and driving the stirring shaft and blades deeper into the grinding cylinder. Simultaneously, a first motor and a second motor are activated. The first motor drives the stirring shaft and blades to rotate forward, while the second motor drives the grinding cylinder to rotate in the opposite direction. This generates stronger shearing and convection forces on the material, improving both the grinding effect and efficiency. Furthermore, the reverse rotation of the grinding cylinder reduces material adhesion to the stirring shaft and cylinder wall, facilitating smooth material discharge and equipment cleaning. A follow-up sealing mechanism seals the top opening of the grinding cylinder during operation. The sealing plate in this mechanism rotates with the grinding cylinder, effectively preventing material from splashing out and causing unnecessary losses, environmental pollution, and harm to nearby workers. In summary, this invention solves the problems in the prior art.

A limiting rod is fixedly connected to the other side of the abutment plate. The limiting rod matches and engages with the limiting groove. A spring is movably fitted on the outside of the pull rod. The two ends of the spring are fixedly connected to the abutment plate and the fixing block respectively.

[0011] A follow-up sealing mechanism includes a bearing sleeve and a sealing plate. The bearing sleeve is fixedly fitted onto the outside of the stirring shaft, and the sealing plate is fixedly fitted onto the outer circumference of the bearing sleeve. The sealing plate is located above the stirring blades, and the size of the sealing plate is larger than the top opening size of the grinding cylinder.

[0012] Furthermore, the bottom of the rotating seat is provided with multiple sliding connectors, and the bottom of each of the multiple sliding connectors is slidably connected to the slide groove.

[0013] Furthermore, each of the two fixed blocks has a stop block fixedly connected to its opposite side, and each of the two stop blocks has a groove on its opposite side, the position and size of which match the pull rod.

[0014] Furthermore, multiple reinforcing support blocks are fixedly installed at the inner corner of the L-shaped bend of the mounting base, and the reinforcing support blocks are fixedly connected to the mounting base by welding.

[0015] Furthermore, a plurality of guide rods are fixedly connected to the top of the mounting frame, and the top ends of the guide rods all movably pass through the mounting base. The length of the guide rods matches the extension and retraction length of the cylinder.

[0016] Furthermore, an annular sealing gasket layer is fixedly attached to the bottom of the sealing plate, and the size and position of the sealing gasket layer match the top opening of the grinding cylinder.

[0018] 1. This technical solution incorporates a rotary grinding cylinder mechanism, allowing materials to be added to the grinding cylinder during operation. The cylinder is then activated, extending to drive the stirring shaft and blades deeper into the grinding cylinder. Simultaneously, the first and second motors are activated. The first motor drives the stirring shaft and blades to rotate forward, while the second motor drives the grinding cylinder to rotate in the opposite direction. This generates stronger shearing and convection forces on the materials, improving both the grinding effect and efficiency. Furthermore, the reverse rotation of the grinding cylinder reduces material adhesion to the stirring shaft and cylinder walls, facilitating smooth material discharge and equipment cleaning, making it highly practical.

[0019] 2. This technical solution incorporates a follow-up sealing mechanism, which seals the top opening of the grinding cylinder during operation. The sealing plate in the follow-up sealing mechanism rotates with the grinding cylinder, effectively preventing material from splashing out of the grinding cylinder and causing unnecessary losses, environmental pollution, and harm to nearby workers, thus further improving the practicality of the device.

[0031] A rotary cylinder mechanism 9 includes a second motor 901, a rotating base 902, a grinding cylinder 903, and fixed blocks 904. The second motor 901 is fixedly mounted on the top of the base 1. The bottom of the rotating base 902 is connected to the output end of the second motor 901. A mounting groove 905 is provided on the top of the rotating base 902. Positioning grooves 906 communicating with the mounting groove 905 are provided on both sides of the mounting groove 905. Handles 907 are fixedly connected to both sides of the grinding cylinder 903. Multiple convex blades 908 are provided at equal intervals on the inner bottom surface of the grinding cylinder 903. The bottom of the grinding cylinder 903 matches and engages with the mounting groove 905. Positioning blocks 909 are fixedly connected to the bottom of both sides of the grinding cylinder 903. The bottom of the positioning blocks 909 matches and engages with the positioning grooves 906. Limiting grooves 910 are provided on opposite sides of the two positioning blocks 909. Two fixed blocks 904 are provided, and both fixed blocks 904 are fixedly mounted on the base 1. A pull rod 911 is movably connected through the top of the rotating seat 902 and close to both sides of the rotating seat 902. The pull rod 911 is an L-shaped cylinder. One end of the pull rod 911 is rotatably connected to the abutment plate 912 through a rotating connector. The other side of the abutment plate 912 is fixedly connected to the limit rod 913. The limit rod 913 matches and engages with the limit groove 910. A spring 914 is movably fitted on the outside of the pull rod 911. The two ends of the spring 914 are fixedly connected to the abutment plate 912 and the fixed block 904, respectively. Follow-up sealing mechanism 10 includes a bearing sleeve 1001 and a sealing plate 1002. The bearing sleeve 1001 is fixedly fitted on the outside of the stirring shaft 7. The sealing plate 1002 is fixedly fitted on the outer circumference of the bearing sleeve 1001. The sealing plate 1002 is located above the stirring blade 8, and the size of the sealing plate 1002 is larger than the top opening size of the grinding cylinder 903.

[0032] The bottom of the rotating seat 902 is provided with multiple sliding connectors 915, the bottom of which are all slidably connected to the slide groove 2; the two fixed blocks 904 are fixedly connected to the opposite sides of the two fixed blocks 904, and the opposite sides of the two fixed blocks 916 are provided with grooves 917, the position and size of which match the pull rod 911; multiple reinforcing support blocks 11 are fixedly installed at the L-shaped inner corner of the mounting seat 3, and the reinforcing support blocks 11 are fixedly connected to the mounting seat 3 by welding; multiple guide rods 12 are fixedly connected to the top of the mounting frame 5, the top of which of the guide rods 12 movably passes through the mounting seat 3, and the length of the guide rods 12 matches the extension length of the cylinder 4; the bottom of the sealing plate 1002 is fitted with an annular sealing gasket 1003, the size and position of which match the top opening of the grinding cylinder 903.

[0033] In the specific implementation process, during operation, materials can be added to the grinding cylinder 903, and then the cylinder 4 is activated to extend it, causing the mounting frame 5 to move downwards. This causes the stirring shaft 7 and stirring blades 8 to penetrate deeper into the interior of the grinding cylinder 903. At this time, the first motor 6 and the second motor 901 can be activated. The first motor 6 drives the stirring shaft 7 and stirring blades 8 to rotate forward to perform high-speed stirring and grinding of the materials inside the grinding cylinder 903. Meanwhile, the second motor 901 drives the rotating seat 902 and the grinding cylinder 903 to rotate in the opposite direction. This, in conjunction with the multiple convex blades 908 on the bottom surface of the grinding cylinder 903, causes the materials inside the grinding cylinder 903 to rotate in the opposite direction. This generates stronger shearing force and convection on the materials, improving the grinding effect and efficiency. Furthermore, the reverse rotation of the grinding cylinder 903 reduces the adhesion of materials to the stirring shaft 7 and the wall of the grinding cylinder 903, which is beneficial for the smooth discharge of materials and the cleaning of the equipment.

[0034] Furthermore, during operation, when the cylinder 4 extends and drives the stirring shaft 7 and stirring blades 8 to move downwards and penetrate into the grinding cylinder 903, the sealing plate 1002 will also move downwards synchronously until the bottom of the sealing plate 1002 abuts against the top of the grinding cylinder 903, and the grinding work can begin. During the grinding work, since the sealing plate 1002 is rotatably connected to the stirring shaft 7 through the bearing sleeve 1001, and the bottom of the sealing plate 1002 abuts against the top of the grinding cylinder 903, the sealing plate 1002 can rotate with the rotation of the grinding cylinder 903, ensuring that the top of the grinding cylinder 903 is always sealed. This effectively prevents materials from splashing out of the grinding cylinder 903, thus avoiding unnecessary losses, environmental pollution, and harm to nearby workers.

[0035] The sliding connection between multiple sliding connectors 915 and the slide groove 2 can improve the overall stability of the rotary seat 902, making it less prone to shaking, thereby improving the stability of the grinding cylinder 903.

[0036] When it is necessary to disassemble the grinding cylinder 903 for unloading, the pull rod 911 can be pulled up to move the abutment plate 912 and the limiting rod 913 until the limiting rod 913 separates from the limiting groove 910. Then, the pull rod 911 can be rotated to lock it into the groove 917 at the stop block 916, thus freeing the operator's hands. The grinding cylinder 903 can then be lifted by the handle 907 until the bottom of the grinding cylinder 903 separates from the mounting groove 905, at which point the grinding cylinder 903 can be removed. During installation, repeat the above operations in reverse order, engaging the bottom of the grinding cylinder 903 with the mounting slot 905 and engaging the positioning block 909 with the positioning slot 906. After releasing the pull rod 911, the spring 914 rebounds, causing the abutment plate 912 and the limiting rod 913 to return to their original positions until the limiting rod 913 engages with the limiting slot 910. This completes the installation and fixation of the grinding cylinder 903. When the rotating seat 902 rotates, the engagement between the positioning block 909 and the positioning slot 906 can be used to rotate the grinding cylinder 903.

[0037] Among them, the reinforcing support block 11 can effectively improve the overall stability of the mounting base 3, making it less prone to shaking;

[0038] Among them, the guide rod 12 can improve the overall stability of the mounting frame 5;

[0039] The sealing gasket 1003 can effectively improve the sealing performance between the sealing plate 1002 and the top opening of the grinding cylinder 903, thereby effectively preventing material from overflowing from the top opening of the grinding cylinder 903 during grinding.

[0040] Working Principle: During operation, material can be added to the grinding cylinder 903. Then, the cylinder 4 is activated, extending it and causing the mounting frame 5 to move downwards. This causes the stirring shaft 7 and stirring blades 8 to penetrate deep into the grinding cylinder 903. As the stirring shaft 7 and stirring blades 8 move into the grinding cylinder 903, the sealing plate 1002 also moves downwards simultaneously until its bottom is firmly against the top of the grinding cylinder 903. At this point, the first motor 6 and the second motor 901 are activated. The first motor 6 drives the stirring shaft 7 and stirring blades 8 to rotate forward, performing high-speed stirring and grinding on the material inside the grinding cylinder 903. Meanwhile, the second motor 901 drives the rotating seat 902 and the grinding cylinder 903 to rotate in the opposite direction. This, in conjunction with the multiple protruding blades 908 on the bottom surface of the grinding cylinder 903, causes the material inside the grinding cylinder 903 to rotate in the opposite direction. This allows for stronger shearing and convection forces on the material, improving both the grinding effect and efficiency. Furthermore, the reverse rotation of the grinding cylinder 903 reduces material adhesion to the stirring shaft 7 and the walls of the grinding cylinder 903, facilitating smooth material discharge and equipment cleaning. During grinding, the sealing plate 1002 is rotatably connected to the stirring shaft 7 via the bearing sleeve 1001, and its bottom abuts against the top of the grinding cylinder 903. Therefore, the sealing plate 1002 rotates with the grinding cylinder 903, ensuring the top of the grinding cylinder 903 is always sealed. This effectively prevents material from splashing out of the grinding cylinder 903, avoiding unnecessary losses, environmental pollution, and harm to nearby workers, further enhancing the device's practicality.
