Technical Field
[0001] This invention relates to the field of ink preparation technology, specifically to a three-roll milling apparatus for ink preparation and its usage method. Background Technology
[0002] Three-roll mills, also known simply as three-roll grinders, can be divided into experimental and production types. They are suitable for manufacturing pastes such as paints, inks, pigments, and plastics. The working principle of a three-roll mill is based on the mutual compression and friction at different speeds of the surfaces of three horizontal rollers to achieve a grinding effect. Three-roll mills are the most effective grinding and dispersing equipment for high-viscosity materials.
[0003] Existing three-roll grinding equipment for ink preparation has grinding rollers that are exposed to the outside, resulting in a large amount of impurities and dust adhering to the surface of the grinding rollers. This affects the grinding operation of the grinding rollers, and the exposed grinding rollers are also susceptible to impact damage, reducing their service life. Summary of the Invention

[0007] A connecting spring, the bottom of which is fixed to the top of the equipment body, and the top of which is fixed to the bottom of the stop block;
[0008] A connecting rod is provided, with its top fixed to the bottom of the slider. A protective cover is fixed to the bottom of the connecting rod, which protects the grinding roller.
[0009] Preferably, a sleeve is fixed to the inner wall of the protective cover, a sleeve rod is slidably installed on the inner wall of the sleeve, a compression spring is fixed to the top of the sleeve rod, and the top of the compression spring is fixed to the inner wall of the sleeve. By setting the compression spring, the cleaning roller can be made to fit tightly against the grinding roller.
[0010] Preferably, the cleaning mechanism includes a long plate, the top of which is attached to the bottom of the sleeve rod. An L-shaped connecting plate is fixed to the bottom of the long plate. A rotating rod is rotatably mounted on the inner side of the L-shaped connecting plate. A cleaning roller is slidably mounted on the outer wall of the rotating rod, which causes the cleaning roller to press against the outer wall of the grinding roller. When the grinding roller needs to be used, it can be started first, causing the grinding roller to rotate against the outer wall of the cleaning roller, thereby cleaning the grinding roller.
[0011] Preferably, a return spring is fixed to one side of the cleaning roller, and a support rod is fixed to the other side of the cleaning roller. The side of the return spring away from the cleaning roller is fixed to a disc, and the disc is fixed to the outer wall of the rotating rod. A fixing plate is fixed to the end of the support rod away from the cleaning roller, and a semi-circular block is fixed to the side wall of the fixing plate.
[0012] Preferably, a support block is fixed to the bottom of the L-shaped connecting plate, and a conical block is fixed to the side wall of the support block. When the grinding roller rotates, it can drive the cleaning roller to rotate. Through the support rod, semi-circular block, support block and conical block, the cleaning roller can rotate and move left and right at the same time, so as to achieve a better cleaning effect on the surface of the grinding roller.
[0013] Preferably, the top of the long plate is provided with a connecting groove, a movable block is slidably installed on the inner wall of the connecting groove, a limit rod is fixed on one side of the movable block, and a handle is fixed on the other side of the movable block.
[0014] Preferably, a limiting hole is formed on the outer wall of the sleeve rod, and the inner wall of the limiting hole fits against the outer wall of the limiting rod.
[0015] Preferably, a moving spring is fixed to the side wall of the moving block, and the side of the moving spring away from the moving block is fixed to the inner wall of the connecting groove.
[0016] Preferably, the slider has a groove, a limit post is slidably installed on the inner wall of the groove, a transmission spring is fixed on the side wall of the limit post, the side of the transmission spring away from the limit post is fixed to the inner wall of the groove, a pull rod is fixed on the side wall of the limit post, a pull ring is fixed at the end of the pull rod, and a limit groove is formed on the fixed rod.
[0017] A method of using a three-roll milling machine, the method comprising the following steps:
[0018] S1. When the grinding roller is not needed, the protective cover can be pushed down to move the slider down. When the protective cover covers the grinding roller, the limiting post will extend into the limiting groove, so that the protective cover can cover the grinding roller for protection.
[0019] S2. When the protective cover covers the grinding roller, the cleaning roller will press against the outer wall of the grinding roller. When the grinding roller needs to be used, the grinding roller can be started first, so that the grinding roller rotates against the outer wall of the cleaning roller, thereby cleaning the grinding roller.
[0020] S3. When the grinding roller rotates, the friction can drive the cleaning roller to rotate, which can cause the support rod to drive the semicircular block to rotate on the conical block. This causes the semicircular block to be subjected to pressure, which in turn causes the semicircular block to drive the cleaning roller to move. As the cleaning roller rotates, it can also move left and right, thus improving the cleaning effect.
[0021] S4. After the cleaning roller is cleaned, the pull ring can be pulled to move the pull rod and the limit post out of the limit groove. Because the connecting spring is in a compressed state, the slider can move the protective cover upward so that the grinding roller can be exposed and grinding can be performed.
[0022] S5. By pulling the handle, the handle can move the moving block, which in turn moves the limiting rod out of the limiting hole, thus releasing the limitation on the long plate and allowing the cleaning mechanism to be removed from the protective cover, making it easier to clean the cleaning roller.
[0023] Compared with the prior art, the present invention provides a three-roll milling device and its method for use in ink preparation, which has the following beneficial effects:
[0024] 1. The three-roll grinding equipment for ink preparation and its usage method: When the grinding rollers are not needed, the protective cover can be pressed down and moved to cover the grinding rollers. By setting the limiting post and the limiting groove, the protective cover can be fixed and can protect the grinding rollers.
[0025] 2. The three-roll grinding equipment for ink preparation and its usage method: When the protective cover covers the grinding roller, the outer wall of the cleaning roller will be in contact with the outer wall of the grinding roller. By starting the grinding roller, the grinding roller can rotate in contact with the cleaning roller, thereby achieving the effect of cleaning the grinding roller.
[0026] 3. The three-roll grinding equipment for ink preparation and its usage method: when the grinding roller rotates, it can drive the cleaning roller to rotate. Through the support rod, semi-circular block, support block and conical block, the cleaning roller can rotate and move left and right at the same time, so as to achieve a better cleaning effect on the surface of the grinding roller.
[0027] 4. The three-roll grinding equipment for ink preparation and its usage method: by pulling the handle, the moving block can be moved, causing the moving block to move the limiting rod out of the limiting hole, thereby releasing the limitation on the cleaning mechanism. The cleaning mechanism can then be removed from the protective cover for easy cleaning. Attached Figure Description

[0038] like Figure 1-9As shown, the present invention provides a technical solution: a three-roll grinding device for ink preparation, including a main body 1, a grinding roller 2 disposed on the main body 1, and a guide plate 3 fixed on the main body 1. When ink needs to be prepared, raw materials can be added to the grinding roller 2. The device is started by connecting an external power source to the main body 1 to make the grinding roller 2 rotate, thereby performing grinding operations. A protective mechanism 4 is disposed on the top of the main body 1, and a cleaning mechanism 8 is disposed inside the protective mechanism 4.
[0039] The aforementioned protective mechanism 4 includes a fixed rod 401, a slider 402, a connecting rod 403, a protective cover 404, a connecting spring 405, a stop block 406, a limiting groove 407, a recess 408, a limiting post 409, a transmission spring 410, a pull rod 411, and a pull ring 412. The fixed rod 401 is fixed to the top of the equipment body 1. A slider 402 is slidably mounted on the outer wall of the fixed rod 401. Two sets of sliders 402 are provided, and the two sets of sliders 402 are symmetrically arranged about the center line of the vertical direction of the protective cover 404 as the axis of symmetry. By sliding the slider 402 on the fixed rod 401, the slider 402 can be guided. A connecting rod 403 is fixed to the bottom of 402, and a protective cover 404 is fixed to the bottom of the connecting rod 403. The protective cover 404 protects the grinding roller 2. A stop block 406 is fixed to the top of the fixing rod 401 to prevent the slider 402 from detaching from the fixing rod 401. A connecting spring 405 is fixed to the bottom of the slider 402, and the bottom of the connecting spring 405 is fixed to the top of the main body 1 of the equipment. When the grinding roller 2 is not needed, the protective cover 404 can be pressed down to move it downward, causing the slider 402 to compress the connecting spring 405. A recess is provided on the slider 402. A limiting post 409 is slidably installed on the inner wall of the groove 408. A transmission spring 410 is fixed to the side of the limiting post 409 away from the protective cover 404. The side of the transmission spring 410 away from the limiting post 409 is fixed to the inner wall of the groove 408. A pull rod 411 is fixed to the side of the limiting post 409 away from the protective cover 404. A pull ring 412 is fixed to the end of the pull rod 411 away from the limiting post 409, and the transmission spring 410 is in a compressed state. Therefore, when the protective cover 404 covers the grinding roller 2, the limiting post 409 will engage with the limiting groove 409 on the fixed rod 401. 7. Alignment: Because the transmission spring 410 is in a compressed state, the limiting post 409 can extend into the limiting groove 407, fixing the slider 402 and the protective cover 404. The protective cover 404 fixes and protects the grinding roller 2, preventing the grinding roller 2 from being exposed to the outside when not in use, which would cause dust and other impurities to fall on it, making it inconvenient for workers to clean the grinding roller 2. It can also prevent the grinding roller 2 from being damaged by collision. A sleeve 5 is fixed to the inner wall of the protective cover 404. A sleeve rod 6 is slidably installed on the inner wall of the sleeve 5. A compression spring 7 is fixed to the top of the sleeve rod 6. The top of the compression spring 7 is fixed to the inner wall of the sleeve 5. A cleaning mechanism 8 is provided at the bottom of the sleeve rod 6.
[0040] The cleaning mechanism 8 includes a long plate 811, an L-shaped connecting plate 801, a rotating rod 802, a cleaning roller 803, a return spring 804, a support rod 806, a disc 805, a semi-circular block 808, a support block 809, and a conical block 810. The top of the long plate 811 is attached to the bottom of the sleeve rod 6. The bottom of the long plate 811 is fixed with the L-shaped connecting plate 801. The rotating rod 802 is rotatably mounted on the inner side of the L-shaped connecting plate 801. The cleaning roller 803 slides on the outer wall of the rotating rod 802. Three sets of cleaning rollers 803 are provided, and the three sets of cleaning rollers 803 are equally spaced inside the protective cover 404. The return spring 804 is fixed to the left side of the cleaning roller 803. The side of the return spring 804 away from the cleaning roller 803 is fixed to the disc 805. Fixed to the outer wall of the rotating rod 802, the cleaning roller 803 can be reset by the reset spring 804. When the protective cover 404 covers the grinding roller 2, the cleaning roller 803 will fit tightly against the outer wall of the grinding roller 2. The compression spring 7 ensures that the cleaning roller 803 always presses against the outer wall of the grinding roller 2, resulting in a uniform pressure and improved cleaning effect. When cleaning the grinding roller 2 is required, the equipment can be started to rotate it. The friction caused by the rotation of the grinding roller 2 will drive the cleaning roller 803 to rotate. A support rod 806 is fixed to the side wall of the cleaning roller 803, and a fixing rod is fixed at the end of the support rod 806 away from the cleaning roller 803. The disk 807 is supported by a support rod 806. A semi-circular block 808 is fixed to the side of the fixed disk 807 away from the support rod 806. A support block 809 is fixed to the bottom of the L-shaped connecting plate 801, and a conical block 810 is fixed to the side wall of the support block 809. When the grinding roller 2 rotates, it drives the support rod 806 to rotate, causing the fixed disk 807 to rotate. This causes the arc surface of the semi-circular block 808 to contact the inclined surface of the conical block 810. When the semi-circular block 808 is subjected to pressure, the support rod 806 drives the cleaning roller 803 to move to the left, compressing the return spring 804. When the semi-circular block 808 rotates to a point where it is no longer in contact with the conical block 810, the semi-circular block 808 is no longer subjected to pressure, and the return spring 804 is compressed. When 04 is in a compressed state, the cleaning roller 803 can move to the right and return to its original position. Then, when the grinding roller 2 rotates in contact with the cleaning roller 803, the cleaning roller 803 can move left and right through the cooperation of the semi-circular block 808 and the conical block 810, thus improving the cleaning effect on the grinding roller 2. When the grinding roller 2 needs to be used, pulling the pull ring 412 causes the pull ring 412 to move the limiting post 409 out of the limiting groove 407, thereby releasing the limitation on the slider 402. Because the connecting spring 405 is in a stretched state, the slider 402 can move the protective cover 404 upwards, exposing the grinding roller 2, thus making the grinding roller 2 usable and convenient for operators. The top of the long plate 811 has a connecting groove 9.A movable block 10 is slidably mounted on the inner wall of the connecting groove 9. A limit rod 13 is fixed to one side of the movable block 10, and a movable spring 11 is fixed to the other side of the movable block 10. The side of the movable spring 11 away from the movable block 10 is fixed to the inner wall of the connecting groove 9. A handle 12 is fixed to the side of the movable block 10 away from the limit rod 13. By pulling the handle 12, the movable block 10 can move the limit rod 13 out of the limit hole 14 opened in the sleeve rod 6, thereby releasing the limitation on the cleaning mechanism 8 and allowing the cleaning mechanism 8 to be removed from the sleeve rod 6 for easy cleaning of the cleaning roller 803.
[0041] A method of using a three-roll milling machine, the method comprising the following steps:
[0042] S1. When the grinding roller 2 is not needed, the protective cover 404 can be pushed down to move the slider 402 down. When the protective cover 404 covers the grinding roller 2, the limiting post 409 will extend into the limiting groove 407, so that the protective cover 404 can cover the grinding roller 2 for protection.
[0043] S2. When the protective cover 404 covers the grinding roller 2, the cleaning roller 803 will press against the outer wall of the grinding roller 2. When the grinding roller 2 needs to be used, the grinding roller 2 can be started first, so that the grinding roller 2 rotates against the outer wall of the cleaning roller 803, thereby achieving the effect of cleaning the grinding roller 2.
[0044] S3. When the grinding roller 2 rotates, the friction can drive the cleaning roller 803 to rotate, which can cause the support rod 806 to drive the semi-circular block 808 to rotate on the conical block 810, so that the semi-circular block 808 is subjected to the squeezing force, which will cause the semi-circular block 808 to drive the cleaning roller 803 to move. In addition, the cleaning roller 803 can also move left and right while rotating, thus making the cleaning effect better.
[0045] S4. After cleaning the cleaning roller 803, the pull ring 412 can be pulled, which can cause the pull rod 411 to move the limiting post 409 out of the limiting groove 407. Because the connecting spring 405 is in a compressed state, the slider 402 can move the protective cover 404 upward, so that the grinding roller 2 can be exposed and grinding operations can be performed.
[0046] S5. By pulling the handle 12, the handle 12 can drive the moving block 10 to move, and the moving block 10 can drive the limiting rod 13 to move out of the limiting hole 14, which can release the limitation on the long plate 811, and the cleaning mechanism 8 can be taken out from the protective cover 404, thus facilitating the cleaning roller 803 to be cleaned.
[0047] 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 scope of protection of the present invention.
