Description

Technical Field

[0001] The present invention relates to the technical field of coating grinding, in particular to a coating grinding machine. Background Art

[0002] During the paint production process, it is generally necessary to first pour the raw materials into a grinding device, and then use the grinding device to grind the raw materials so that the raw materials can be fully mixed to obtain a paint that meets the standards; therefore, the grinding process is one of the key steps in paint production.

[0003] Existing paint grinders generally use a manual proportioning method to first quantitatively proportion the raw materials, and then grind the raw materials through the grinding disk in the grinder. Although this method is highly efficient and has a fast grinding speed, the proportioning speed of this scheme is slow and cannot be automatically and quickly proportioned, thereby failing to further increase the grinding speed; existing paint grinders are also unable to automatically screen and re-grind insufficiently ground raw materials, thereby failing to improve the grinding effect; therefore, a paint grinder that can improve the raw material proportioning efficiency, screen the raw materials, and grind them multiple times is needed to solve the shortcomings of existing paint grinders.

[0004] For example, the patent with announcement number CN118698707B provides a paint grinding machine, which includes a temporary storage box, a mixing box, a screening box, and an integrated grinding, screening and mixing functional linkage component. The grinding, screening and mixing integrated functional linkage component realizes the grinding of solid paint, screening of solid paint, and mixing and stirring of liquid paint by rotating a driving motor 3. This application uses the same driving source to achieve multiple groups of effects, and the overall structure is compact and can reduce energy consumption. Although this solution can realize the integrated control and drive of solid paint grinding, solid paint screening, and mixing and stirring of liquid paint, the raw material ratio still needs to be manually proportioned, and it is impossible to realize automated proportioning and loading, and it is impossible to further improve the efficiency of raw material grinding and mixing; this solution cannot realize the recycling of vibration kinetic energy, and cannot rely on the mechanical vibration generated by the motor and grinding disc during the grinding process to directly drive the screen to vibrate and screen the paint; this solution also cannot utilize the heat generated during the continuous operation of the motor into the grinding process, thereby failing to increase the grinding temperature and further improve the efficiency and effect of grinding; this solution also cannot automatically adjust the frequency and intensity of vibration according to the different grinding disc speeds.

[0043] Working principle of the present invention: Figure 1 and Figure 2The usage and corresponding scenarios of the present invention are given. The posture control of the paint grinding process is determined by the feeding device 1, the grinding device 5, and the material control device 6. The posture of the feeding device 1 is determined by the grinding device 5, and the posture of the material control device 6 is determined by the grinding device 5. Therefore, the grinding device 5 is the core of the paint grinding process.

[0044] Taking Example 1 as an example, the control console 103 on the feeding device 1 drives the grinding motor 504 on the grinding device 5 to rotate counterclockwise, and the grinding motor 504 drives the grinding assembly 507 and the grinding bracket 506 to rotate counterclockwise, and the grinding bracket 506 drives the switch baffle 305 to slide counterclockwise through the grinding one-way teeth 509 on the grinding shell 501, so that the switch notch 304 on the side of the switch shell 301 is opened.

At the same time, the grinding disc 513 on the grinding component 507 grinds the raw material to realize automatic proportioning and automatic grinding. Function: During the grinding process, the faster the rotation speed of the grinding assembly 507 is, the centrifugal force generated will drive the sliding resistor 519 to be thrown outward, so that the resistance value of the bar resistor 520 connected to the circuit is reduced, thereby increasing the voltage supplied by the console 103 to the piezoelectric actuator 516, so that the vibration frequency and intensity of the piezoelectric actuator 516 are increased, thereby realizing the auxiliary crushing function in the grinding process; the vibration generated by the piezoelectric actuator 516 will be transmitted to the material control shaft 603 of the material control device 6 through the sliding column 512 and the grinding disk 513, and then the vibration generated will be transmitted to the vibration screen 202 of the vibration selection device 2 through the vibration column 606, so that the vibration screen 202 also vibrates, thereby realizing the auxiliary crushing function in the grinding process; the vibration generated by the piezoelectric actuator 516 will be transmitted to the material control shaft 603 of the material control device 6 through the sliding column 512 and the grinding disk 513, and then the vibration generated will be transmitted to the vibration screen 202 of the vibration selection device 2 through the vibration column 606, so that the vibration screen 202 also vibrates, thereby realizing The vibration kinetic energy is recycled and the vibration screening function of the coating is realized; during the grinding process, since the grinding motor 504 is in a long-term operation state, the grinding motor 504 will generate a large amount of heat, and the heat is transferred to the first heat-conducting column 401 and the second heat-conducting column 404 through the heat dissipation tube 403 on the thermal energy component 4, and then from the first heat-conducting column 401 and the second heat-conducting column 404 to the third heat-conducting column 502 and the fourth heat-conducting column 503, and then from the third heat-conducting column 502 and the fourth heat-conducting column 503 to the first heating ring 514 and the second heating ring 518, so that the heat is finally transferred to the raw material to realize the heat recycling and heating function of the raw material.

[0045] Specifically, such as Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13As shown, the control console 103 at the upper end of the protective cover 102 drives the grinding motor 504 at the lower end of the protective cover 102 to rotate counterclockwise, and the grinding motor 504 drives the grinding shell 510 and the grinding bracket 506 of the grinding assembly 507 to rotate counterclockwise through the transmission shaft 505, and the grinding bracket 506 drives the grinding one-way teeth 509 on the grinding shell 501 to rotate counterclockwise, and the grinding one-way teeth 509 drive the baffle body 306 to slide counterclockwise on the switch gap 304 by contacting with the back of the flexible buckle 307, so that the switch gap 304 on the side of the switch shell 301 is opened, and at the same time, the grinding disc 513 also drives the material control shaft 603 to rotate counterclockwise through the sliding column 512, and the material control shaft 603 is driven by the air pressure plunger 609 The pneumatic handle 610 rotates counterclockwise, and the pneumatic handle 610 drives the material control cam 604 to rotate counterclockwise along with the one-way turntable 608 through the material control protrusion 607. Then the material control cam 604 drives the pushing assembly 105 to reciprocate in the pushing chamber 108 through the spring at the rear end of the U-shaped plunger 109. At this time, the raw materials are first poured into the storage chamber 106 through the feeding pipe 104. When the U-shaped plunger 109 extends outward, the raw materials will fall into the pushing chamber 108 from the discharge port 107. When the U-shaped plunger 109 retracts inward, the U-shaped plunger 109 will drive the raw materials from the pushing chamber 108 of the feeding shell 101 into the switch notch 304 on the side of the switch shell 301. Then the raw materials pass through the switch notch 304. 4 and the grinding channel 508 on the side of the grinding shell 501 enter the top of the abrasive base plate 303, then the grinding motor 504 drives the grinding shaft 511 of the grinding assembly 507 and the grinding bracket 506 to rotate clockwise, the grinding bracket 506 drives the switch baffle 305 to close the switch gap 304 through the grinding one-way teeth 509 on the grinding shell 501, then the grinding one-way teeth 509 will squeeze the flexible buckle 307 outward, so that the grinding one-way teeth 509 are out of contact with the side of the flexible buckle 307, and at the same time, the grinding shaft 511 drives the grinding disc 513 to rotate clockwise through the grinding shell 510, and the grinding disc 513 will grind the raw materials above the abrasive base plate 303, thereby realizing automatic proportioning and automatic feeding. Grinding function; during the grinding process, when the rotation speed of the grinding assembly 507 is accelerated, the centrifugal force generated will drive the sliding resistor 519 to be thrown outward, so that the resistance value of the bar resistor 520 connected to the circuit is reduced, thereby increasing the voltage supplied by the console 103 to the piezoelectric actuator 516, so that the vibration frequency and intensity of the piezoelectric actuator 516 are increased, thereby realizing the auxiliary crushing function in the grinding process; when it is necessary to set the proportion, the pusher electric push rod 110 on the U-shaped plunger 109 will drive the pusher plunger 111 to slide in the U-shaped plunger 109, so that the contact distance between the pusher plunger 111 and the material control cam 604 changes, thereby changing the initial position and advancement distance of the U-shaped plunger 109 to control the volume of the raw material pushed in each time;When grinding is complete, the material control handle 605 is manually driven to slide downward. The material control handle 605 drives the material control turntable 601 to slide downward via the material control shaft 603. The material control turntable 601 drives the material control plug 602 to be pulled out of the material outlet 302, allowing the paint to be discharged from the material outlet 302, thus completing the paint discharge function. The third heat conducting column 502 and the fourth heat conducting column 503 are used to transfer heat; the first heating coil 514 and the second heating coil 518 are used to transfer heat to the paint; the first insulation coil 515 and the second insulation coil 517 are used to block heat.

[0046] like Figure 5 As shown, the vibration generated by the piezoelectric actuator 516 will be transmitted to the material control shaft 603 of the material control device 6 through the sliding column 512 and the grinding disk 513, and then the generated vibration will be transmitted to the vibration screen 202 through the vibration column 606, so that the vibration screen 202 follows the vibration in the vibration shell 201, thereby realizing the recycling of vibration kinetic energy and the vibration screening function of the paint; the limit spring 203 is used to drive the material control handle 605 to rebound upward; the vibration spring 205 at the upper end of the vibration base 204 drives the vibration screen 202 to rebound upward through elastic force.

[0047] like Figure 8 As shown, during the grinding process, the grinding motor 504 generates a large amount of heat, which is transferred to the first heat-conducting column 401 and the second heat-conducting column 404 through the heat dissipation tube 403, and then transferred from the first heat-conducting column 401 and the second heat-conducting column 404 to the third heat-conducting column 502 and the fourth heat-conducting column 503, and then transferred from the third heat-conducting column 502 and the fourth heat-conducting column 503 to the first heating ring 514 and the second heating ring 518, so that the heat is finally transferred to the raw material to realize heat recovery and heating of the raw material; the heat sink 402 outside the heat dissipation tube 403 is used for heat dissipation of the grinding motor 504.
