Detailed Implementation

[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 Figure 1-6 This embodiment provides a technical solution: an ink production grinding device, including a grinding chamber 1 and a locking mechanism 5;

[0026] Grinding chamber 1: The lower ends of the inner walls on both the front and rear sides are fixedly connected to guide rails 4. The lower ends of the left and right sides of the grinding chamber 1 are provided with rectangular openings. A sliding frame 6 is slidably connected between the two rectangular openings and the two guide rails 4. A filter plate 7 is fixedly connected inside the sliding frame 6. A controller 15 is provided on the right side of the grinding chamber 1. The input end of the controller 15 is electrically connected to an external power source.

[0027] Locking mechanism 5 includes a support 51, a rotating shaft 52, a locking handle 53, and a locking pin 54. The supports 51 are symmetrically fixed to the lower ends of the front and rear surfaces of the grinding chamber 1. A rotating shaft 52 is rotatably connected between any two laterally adjacent supports 51. Locking handles 53 are fixedly connected to both ends of the rotating shaft 52. Locking pins 54 are fixedly connected to both ends of the front and rear surfaces of the sliding frame 6. A locking port is provided at the end of the locking handle 53 furthest from the central axis of the adjacent rotating shaft 52, and the locking port 54 is fitted into the adjacent locking pin 54. Locking mechanism 5 also includes a limit cap 55, a connecting hole 56, and a pin 57. The limit cap 55 is sleeved on the left and right ends of the two rotating shafts 52. A positioning hole is provided inside each limit cap 55. The front and rear surfaces of the rotating shafts 52... Both ends are provided with connecting holes 56, and pins 57 are tightly inserted between the connecting holes 56 and the adjacent positioning holes. The pin of the torsion spring 58 near the center of the grinding chamber 1 can be engaged with the end of the adjacent support 51 away from the center of the grinding chamber 1 through a snap fastener. The pin of the torsion spring 58 away from the center of the grinding chamber 1 can be engaged with the end of the adjacent locking handle 53 near the center of the grinding chamber 1 through a snap fastener. Periodically unengage the snap fasteners, then remove the pins 57 to lock the relative position of the limit cap 55 and the adjacent rotating shaft 52. Then move the limit cap 55 away from the center of the grinding chamber 1. After the limit cap 55 has finished contacting the adjacent rotating shaft 52, move the locking handle 53 outward, then move the old torsion spring 58 outward, and then put the new torsion spring 58 back on. The locking handle 53 is then slid back onto the outer surface of the corresponding rotating shaft 52. When the end face of the positioning ring away from the center of the grinding chamber 1 is in contact with the end face of the adjacent locking handle 53 near the center of the grinding chamber 1, the locking handle 53 is stopped. Then, the limiting cap 55 is fitted onto the corresponding end of the rotating shaft 52. Finally, the pin 57 is reinserted between the adjacent connecting hole 56 and the positioning hole to lock the position of the limiting cap 55 and the adjacent rotating shaft 52. At this time, the end face of the limiting cap 55 near the center of the grinding chamber 1 is in contact with the end face of the adjacent locking handle 53 away from the center of the grinding chamber 1, thereby achieving lateral limiting of the locking handle 53. Then, the buckle is re-engaged to achieve periodic replacement of the torsion spring 58 and prevent the aging of the torsion spring 58 from affecting the sliding frame. The locking mechanism 5 includes a position locking effect. The end face of the limit cap 55 near the center of the grinding chamber 1 is in contact with the end face of the adjacent locking handle 53 away from the center of the grinding chamber 1. Positioning rings are fixedly connected to both ends of the rotating shaft 52. The end face of the positioning ring away from the center of the grinding chamber 1 is in contact with the end face of the adjacent locking handle 53 near the center of the grinding chamber 1. The locking mechanism 5 also includes torsion springs 58, which are positioned between the end of the locking handle 53 near the center of the grinding chamber 1 and the end of the adjacent support 51 away from the center of the grinding chamber 1. The springs 58 are sleeved on the outer surface of the adjacent rotating shaft 52. When ink residue accumulates to a certain extent on the upper end of the filter plate 7, the controller 15 shuts off the motor 10, and then the two rotating shafts 52 rotate away from the center of the grinding chamber 1.Rotating the shaft 52 outward causes the two adjacent locking handles 53 to rotate away from the center of the grinding chamber 1. The locking ports inside the locking handles 53 engage with the middle of the adjacent locking pins 54, thus ending the lateral limitation on the sliding frame 6. At the same time, the outward rotation of the locking handles 53 causes the adjacent torsion springs 58 to torsion, and then pulls the sliding frame 6 to the left or right. When the sliding frame 6 is completely separated from the two rectangular openings and the two guide rails 4, the filter plate 7 leaves the interior of the grinding chamber 1, allowing for quick disassembly of the filter plate 7. After cleaning the ink residue on the upper part of the filter plate 7, the sliding frame is then removed. 6. When the sliding frame 6 slides back between the two rectangular openings and the two guide rails 4, and the right end face of the sliding frame 6 coincides with the right surface of the grinding chamber 1, and the left end face of the sliding frame 6 coincides with the left surface of the grinding chamber 1, stop moving the sliding frame 6. Then, the limiting of the rotating shaft 52 ends. The torsional force of the spring 58 reacts to the adjacent locking handle 53. The locking handle 53 rotates with the adjacent rotating shaft 52 towards the center of the grinding chamber 1. The locking holes of the locking handles 53 engage with the middle of the adjacent locking pins 54, thereby achieving the lateral limiting of the sliding frame 6 and thus enabling the rapid installation of the filter plate 7.

[0028] The grinding chamber 1 has a linkage chamber 14 located at the upper end of its front surface. A main grinding roller 2 is rotatably connected to the upper end of the interior of the grinding chamber 1. Four secondary grinding rollers 3, evenly distributed, are rotatably connected to the upper end of the interior of the grinding chamber 1. All four secondary grinding rollers 3 are fitted with the main grinding roller 2. The front ends of both the secondary grinding rollers 3 and the main grinding roller 2 extend into the interior of the linkage chamber 14. Driven gears 9 are fixedly connected to the front ends of the four secondary grinding rollers 3. A drive gear 8 is fixedly connected to the front end of the main grinding roller 2. All four driven gears 9 mesh with the drive gear 8. Both the four driven gears 9 and the drive gear 8 are located inside the linkage chamber 14. The upper end of the rear surface of the grinding chamber 1 is provided with… The front end of the motor 10 output shaft is fixedly connected to the rear end of the main grinding roller 2. The input end of the motor 10 is electrically connected to the output end of the controller 15. The controller 15 enables the motor 10 to operate. The rotation of the output shaft of the motor 10 drives the main grinding roller 2 to rotate. The rotation of the main grinding roller 2 drives the drive gear 8 to rotate. The rotation of the drive gear 8 drives the four driven gears 9 to rotate. The rotation of the four driven gears 9 drives the adjacent secondary grinding roller 3 to rotate. The rotation direction of the secondary grinding roller 3 is opposite to that of the main grinding roller 2. The secondary grinding roller 3, the main grinding roller 2, and the inner walls of the left and right sides of the grinding chamber 1 support and squeeze each other to achieve the grinding of ink raw materials and the extraction of ink.

[0029] The grinding chamber 1 is equipped with a feed hopper 12 at its upper end, through which ink raw materials are added to the grinding chamber 1. A conveying hopper 11 is fixedly connected to the middle of the grinding chamber 1. An inclined discharge plate 13 is fixedly connected to the lower end of the grinding chamber 1. The ink and ink raw material residue generated during grinding are concentrated and fall to the upper end of the filter plate 7 under the guiding action of the conveying hopper 11. The ink falls to the upper end of the inclined discharge plate 13 through the evenly distributed filter holes inside the filter plate 7, and then flows out along the inclined surface of the inclined discharge plate 13 under its own gravity.

[0030] The working principle of the ink production grinding device provided by this utility model is as follows: During operation, the operator first places the grinding chamber 1, the linkage chamber 14, and other mechanisms stably in the horizontal working area. After stable placement, the operator adds ink raw materials into the grinding chamber 1 through the feed hopper 12. Simultaneously, the controller 15 activates the motor 10. The output shaft of the motor 10 rotates, driving the main grinding roller 2 to rotate. The rotation of the main grinding roller 2 drives the drive gear 8 to rotate, which in turn drives four driven gears 9 to rotate. The rotation of each of the four driven gears 9 drives the adjacent secondary grinding roller 3 to rotate. The rotation direction of the secondary grinding roller 3 is the same as that of the main grinding roller 10. The grinding rollers 2 rotate in opposite directions. The secondary grinding roller 3, the main grinding roller 2, and the inner walls of the left and right sides of the grinding chamber 1 support and squeeze each other to grind the ink raw materials and extract the ink. The ink and the ink raw material residue generated during grinding are guided by the feeding hopper 11 and fall to the upper end of the filter plate 7. The ink falls through the evenly distributed filter holes inside the filter plate 7 to the upper end of the inclined discharge plate 13, and then flows out along the inclined surface of the inclined discharge plate 13 under its own gravity. When the ink raw material residue on the upper end of the filter plate 7 accumulates to a certain extent, the motor 10 is turned off by the controller 15, and then personnel move away from the grinding chamber. Rotating the two shafts 52 in the center direction causes the two adjacent locking handles 53 to rotate away from the center of the grinding chamber 1. The locking ports inside the locking handles 53 engage with the middle of the adjacent locking pins 54, thus ending the lateral limitation on the sliding frame 6. At the same time, the outward rotation of the locking handles 53 causes the adjacent torsion springs 58 to exert a torsional force. Then, the operator pulls the sliding frame 6 to the left or right. When the sliding frame 6 is completely separated from the two rectangular openings and the two guide rails 4, the filter plate 7 leaves the interior of the grinding chamber 1, allowing for quick disassembly of the filter plate 7. The ink residue on the upper part of the filter plate 7 is then cleaned. After processing, slide the sliding frame 6 back into the space between the two rectangular openings and the two guide rails 4. When the right end face of the sliding frame 6 coincides with the right surface of the grinding chamber 1 and the left end face of the sliding frame 6 coincides with the left surface of the grinding chamber 1, stop moving the sliding frame 6. Then, end the limiting of the rotating shaft 52. The torsional force of the spring 58 reacts to the adjacent locking handle 53. The locking handle 53 follows the adjacent rotating shaft 52 and rotates towards the center of the grinding chamber 1. The locking port of the locking handle 53 engages with the middle of the adjacent locking post 54, thereby achieving the lateral limiting of the sliding frame 6 and thus achieving the rapid installation of the filter plate 7.

[0031] It is worth noting that the controller 15 disclosed in the above embodiments controls the operation of the motor 10 using methods commonly used in the prior art.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
