Description

Technical Field

[0001] This application relates to the field of grinding equipment technology, and in particular to a three-roll grinding apparatus for ink. Background Technology

[0002] The three-roll mill is a key piece of equipment in the ink production process. It grinds and refines ink raw materials through the relative rotation of three rollers, ensuring the uniformity and fineness of the ink. The ground ink needs to be discharged and collected through a guide plate. Traditional three-roll mill devices usually have a single inclined plate structure for the guide plate, and the ink flows in a ribbon-like manner when discharged, and can only be collected at a single position at the end of the guide plate.

[0003] In actual production, there are often scenarios where ground ink needs to be packaged into multiple small containers. In such cases, operators must frequently move the containers or use additional diversion tools, making the operation cumbersome and inefficient. Furthermore, the poor stability of the diversion tool's fit with the guide plate easily leads to ink leakage and uneven diversion, resulting in material waste and increased subsequent cleaning workload, severely impacting operational convenience and production efficiency. Therefore, there is an urgent need for a three-roll grinding device for ink that can achieve convenient diversion and stable collection. Summary of the Invention

[0004] To improve the ease of operation of a three-roll grinding apparatus for ink, this application provides a three-roll grinding apparatus for ink.

[0005] This application provides a three-roll grinding apparatus for ink, which adopts the following technical solution: A three-roll milling device for ink includes a three-roll mill, on which an oil guide plate is installed to guide the ink out. The oil guide plate is inclined and consists of a bottom plate and a side plate. An oil separating component is detachably installed on the oil guide plate. The oil separating component consists of two baffles arranged in an A-shape. The baffles have openings for ink to flow out.

[0006] By adopting the above technical solutions, the inclined oil guide plate can utilize gravity to achieve natural ink delivery without the need for additional power. The oil separation component adopts a detachable design, which is convenient for flexible installation or disassembly according to usage needs, and is suitable for both single collection and diversion collection scenarios. The A-shaped baffle can divert the ink flowing on the oil guide plate to both sides, so that the ink is guided by the baffle to converge on the side plates and finally flows out through the notch, achieving simultaneous collection at two points. This eliminates the need for operators to frequently adjust the position of the collection container, significantly improving dispensing efficiency. At the same time, the A-shaped baffle can guide the direction of ink flow, avoid ink diffusion, and reduce the risk of leakage.

[0007] In one specific implementation, the side plate has a slot for inserting the baffle.

[0008] By adopting the above technical solution, the slot provides a precise installation and positioning structure for the baffle, enabling the baffle to be quickly inserted into the side plate and initially fixed, simplifying the installation process of the oil distribution assembly; at the same time, the cooperation between the slot and the baffle can limit the horizontal displacement of the baffle, ensuring the stability of the baffle after installation, avoiding the baffle from shifting due to ink impact, and ensuring the stability of the diversion effect.

[0009] In one specific implementation, a pusher is installed on the side plate to abut against the baffle. The pusher includes a fixed sleeve, which is installed on the side wall of the side plate. A telescopic rod is slidably installed on the fixed sleeve. A first spring is installed on the telescopic rod. The end of the first spring away from the telescopic rod is connected to the fixed sleeve. A pressure plate is installed on the end of the telescopic rod away from the fixed sleeve. A guide slope is provided on the pressure plate.

[0010] By adopting the above technical solution, the pusher can automatically tighten and fix the baffle after it is inserted into the slot: when installing the baffle, the baffle presses the pressure plate through the guide slope, causing the telescopic rod to slide into the fixed sleeve and compress the first spring; when the baffle is installed in place, the elastic restoring force of the first spring pushes the telescopic rod, causing the pressure plate to press tightly against the side wall of the baffle, firmly fixing the baffle in the slot, further improving the installation stability of the baffle and preventing the baffle from loosening due to equipment vibration or ink impact during the grinding process; the design of the guide slope makes the baffle insertion process smoother, without the need to deliberately align the pressure plate position, reducing the installation difficulty; at the same time, the elastic clamping structure of the pusher is adaptable to baffles of different thicknesses, improving the versatility of the device.

[0011] In one specific implementation, the baffle is equipped with a blocking component that blocks the gap and changes the size of the gap. The baffle has a sliding groove. The blocking component includes a sliding plate. The sliding plate is slidably mounted on the baffle through the sliding groove. A first fixing plate is installed at one end of the sliding plate, and a baffle plate is installed on the first fixing plate.

[0012] By adopting the above technical solution, the blocking component can flexibly adjust the flow area of ​​the notch according to the collection needs: by pushing the slide plate along the chute, the baffle can be moved synchronously, changing the blocking range of the baffle on the notch, thereby adjusting the ink outflow rate; when a large flow rate collection is required, the baffle can be moved to the edge of the notch to make the notch completely open; when a small flow rate dispensing or adjustment of the flow balance on both sides is required, the baffle can be moved to partially block the notch to achieve flow control; the chute provides a stable sliding guide for the slide plate, ensuring that the baffle does not deviate during the movement and ensuring the accuracy of flow rate adjustment.

[0013] In one specific implementation, the baffle is slidably mounted on the first fixed plate, the baffle has a movable groove, a crossbar is mounted on the first fixed plate, the crossbar passes through the movable groove, a second spring is mounted on the crossbar, and the end of the second spring away from the crossbar is connected to the baffle; a rotating rod is rotatably mounted on the baffle, a locking piece is mounted on the rotating rod, a second fixed plate is mounted on the sliding plate, and the locking piece is locked and fixed between the second fixed plate and the baffle by rotating into place.

[0014] By adopting the above technical solution, the sliding structure and locking structure of the baffle plate work together to achieve stable fixation after flow adjustment: When adjusting the position of the baffle plate, first rotate the lever to disengage the locking plate from the clamping state between the second fixed plate and the baffle plate. At this time, the elastic force of the second spring pushes the baffle plate upward to slide, separating the baffle plate from the oil guide plate, reducing sliding resistance, and facilitating smooth adjustment of the baffle plate position; after adjustment, press the baffle plate downward to make the first pressure pad fit against the oil guide plate, and then rotate the lever to turn the locking plate between the second fixed plate and the baffle plate. The friction between the locking plate and the second fixed plate and the baffle plate is used to lock the baffle plate, preventing the baffle plate from shifting under the impact of ink; the cooperation between the crossbar and the movable groove limits the sliding stroke of the baffle plate, preventing the baffle plate from disengaging from the first fixed plate and improving structural stability; the setting of the second spring not only facilitates the lifting and adjustment of the baffle plate, but also assists the baffle plate in pressing the oil guide plate when locked, enhancing the sealing effect.

[0015] In one specific implementation, a locking pad is installed on the baffle to abut against the locking plate, and the locking pad has a semi-circular cross-section.

[0016] By adopting the above technical solution, the semi-circular locking pad has an elastic buffering effect. When the locking plate rotates between the second fixed plate and the baffle, the locking pad is squeezed and produces elastic deformation, thereby applying a continuous clamping force to the locking plate, enhancing the friction between the locking plate and the second fixed plate and the baffle, improving the locking effect, and preventing the locking plate from loosening accidentally. At the same time, the semi-circular locking pad can reduce the frictional resistance when the locking plate rotates, making the locking plate rotation in and out operation smoother and improving the convenience of adjustment.

[0017] In one specific implementation, a first pressure pad is installed on the side of the baffle near the oil guide plate, and the first pressure pad is made of rubber.

[0018] By adopting the above technical solution, the first pressure pad made of rubber has good elasticity and sealing performance. When the baffle plate presses against the oil guide plate, the first pressure pad can fill the gap between the baffle plate and the oil guide plate, preventing ink from leaking from the gap and avoiding raw material waste and equipment contamination. At the same time, the rubber material has a large friction, which can enhance the adhesion stability between the baffle plate and the oil guide plate and further prevent the baffle plate from shifting. In addition, the rubber material is soft and will not cause scratch damage to the surface of the oil guide plate, thus extending the service life of the oil guide plate.

[0019] In one specific implementation, a sealing gasket is installed on the side of the baffle near the oil guide plate.

[0020] By adopting the above technical solution, the sealing gasket can fill the gap between the baffle and the bottom plate of the oil guide plate to form a sealing structure, prevent ink from leaking from the bottom of the baffle, ensure that all ink flows along the baffle guide and flows out from the gap, and improve the integrity of diversion and collection; at the same time, the elasticity of the sealing gasket can compensate for installation errors, making the baffle and the oil guide plate fit more tightly, further improving structural stability and reducing the impact of equipment vibration on the sealing effect.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. This application achieves convenient ink diversion through a detachable A-shaped ink-separating component, changing the traditional single collection method to simultaneous collection at two locations. This eliminates the need for operators to frequently adjust the collection container, significantly improving dispensing efficiency and ease of operation. The detachable design of the ink-separating component is adaptable to different collection scenarios, ensuring versatility.

[0022] 2. The oil separation component is quickly installed and securely fixed by the cooperation of the push-tightening part and the slot. The design of the guide slope simplifies the installation process. The elastic clamping structure of the first spring ensures the stability of the baffle under equipment vibration and ink impact, and avoids loosening and displacement.

[0023] 3. The setting of the shielding component enables flexible adjustment of the flow area of ​​the gap, and can accurately control the ink outflow according to the collection needs. At the same time, the locking structure of the baffle ensures the stability after adjustment. The first pressure pad and the sealing pad enhance the sealing of the device, prevent ink leakage, and reduce raw material waste and equipment contamination. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0033] This application discloses a three-roll grinding apparatus for ink, referring to... Figure 1 and Figure 2 The invention includes a three-roll mill 1, which is the prior art. An oil guide plate 2 for guiding ink discharge is fixedly installed on the three-roll mill 1. The oil guide plate 2 is inclined. The end of the oil guide plate 2 away from the three-roll mill 1 is lower than the end of the oil guide plate 2 connected to the three-roll mill 1. An oil separation component 3 is detachably installed on the oil guide plate 2.

[0034] Reference Figure 2 and Figure 3 The oil guide plate 2 consists of a base plate 21 and two side plates 22. The two side plates 22 are fixedly connected to the base plate 21 perpendicularly, and the two side plates 22 are installed in a figure-eight shape.

[0035] Reference Figure 2 , Figure 3 and Figure 4The oil separating component 3 includes two baffles 31, which are fixedly connected in an A-shape. A handle 32 is fixedly installed on the baffles 31. The baffles 31 have notches 311 for ink to flow out. A sealing gasket 313 made of rubber is fixedly installed on the bottom surface of the baffles 31. The side plate 22 has a slot 221 for inserting the baffles 31. A pusher 33 for pressing against the baffles 31 is fixedly installed on the side plate 22. The pusher 33 includes a fixing sleeve 331, which is fixedly installed on the side wall of the side plate 22. A telescopic rod 332 is slidably installed on the fixing sleeve 331. A first spring 333 is fixedly installed on the telescopic rod 332. The end of the first spring 333 away from the telescopic rod 332 is fixedly connected to the fixing sleeve 331. A pressure plate 334 is fixedly installed on the end of the telescopic rod 332 away from the fixing sleeve 331. A guide slope 3341 is provided on the pressure plate 334.

[0036] Hold the handle 32, align the baffle 31 with the slot 221 on the side plate 22, and then insert the baffle 31 into the side plate 22. When the baffle 31 is inserted into the side plate 22, the baffle 31 will push the pressure plate 334 towards the fixed sleeve 331 through the action of the guide slope 3341 on the pressure plate 334. The telescopic rod 332 will compress the first spring 333. After the baffle 31 is installed, the first spring 333 will support the pressure plate 334 to press against the baffle 31, pressing it tightly and enhancing the stability of the baffle 31. When the three-roll mill 1 grinds ink and produces ink, the ink will flow on the oil guide plate 2. When it flows to the baffle 31, the baffle 31 will divide the ink, causing the ink to flow and collect on both sides of the side plate 22, thus facilitating the workers to collect it in small containers at two locations below the oil guide plate 2.

[0037] Reference Figure 5 , Figure 6 and Figure 7 A blocking component 34, which can change the size of a blocking notch 311, is installed on the baffle 31. A sliding groove 312 is provided on the baffle 31. The blocking component 34 includes a sliding plate 341, which is slidably mounted on the baffle 31 via the sliding groove 312. A first fixing plate 342 is fixedly installed at one end of the sliding plate 341. A baffle 344 is slidably mounted on the first fixing plate 342, and a movable groove 3441 is provided on the baffle 344. A crossbar 343 is fixedly installed on the first fixing plate 342, passing through the movable groove 3441. A second spring 3442 is fixedly installed on the top surface of the crossbar 343, and the end of the second spring 3442 away from the crossbar 343 is fixedly connected to the baffle 344. A first pressure pad 3443, made of rubber, is fixedly installed on the bottom surface of the baffle 344.

[0038] A second fixing plate 345 is fixedly installed at the end of the skateboard 341 away from the first fixing plate 342. The second fixing plate 345 is an L-shaped plate with anti-slip texture. A rotating rod 346 is rotatably installed on the baffle 344. A locking plate 3461 is fixedly installed on the rotating rod 346. A second pressure pad 3462, also made of rubber, is fixedly installed on the top surface of the locking plate 3461. A locking pad 347, also made of rubber, is fixedly installed on the top surface of the baffle 31. The locking pad 347 has a semi-circular cross-section.

[0039] When the position of the baffle 344 needs to be adjusted, first rotate the rotating rod 346 to rotate the locking plate 3461 and the second pressure pad 3462 away from the locking pad 347. After the locking plate 3461 leaves the locking pad 347 and the second fixing plate 345, the second spring 3442 will support the baffle 344 upward, causing the baffle 344 to slide upward on the first fixing plate 342. The baffle 344 rises, causing the first pressure pad 3443 to rise, avoiding friction between the first pressure pad 3443 and the oil guide plate 2, thereby facilitating the movement of the baffle 344. Push the second fixing plate 345, which causes the slide plate 341 to slide on the baffle 31 to adjust the position of the baffle plate 344. The baffle plate 344 covers the notch 311 on the baffle 31, changing the size of the notch 311. After the baffle plate 344 is adjusted, press the baffle plate 344 down so that the first pressure pad 3443 contacts the oil guide plate 2 again. Then rotate the rotating rod 346 to rotate the locking plate 3461 between the locking pad 347 and the second fixing plate 345. The elastic locking pad 347 squeezes and presses the locking plate 3461 between the locking pad 347 and the second fixing plate 345, thus completing the fastening of the baffle plate 344 and preventing the baffle plate 344 and the slide plate 341 from sliding.

[0040] The implementation principle of this application embodiment is as follows: During use, the oil-separating component 3 is selected for installation based on collection needs. When single collection is required, the oil-separating component 3 is not installed, and the ground ink flows directly along the oil guide plate 2 to the end for collection. When diverted collection is required, the baffle 31 is inserted into the slot 221 of the side plate 22 by the handle 32, and the first spring 333 of the pusher 33 pushes the pressure plate 334 to press against the baffle 31, thereby quickly fixing the oil-separating component 3. When the ink flows to the baffle 31, it is diverted to both sides under the guidance of the A-shaped baffle 31, flows out through the notch 311, and is collected synchronously by the two collection containers.

[0041] To adjust the ink flow rate, rotate lever 346 to unlock baffle 344. The second spring 3442 then pushes baffle 344 up, pushing slide plate 341 to adjust the position of baffle 344, thus changing the flow area of ​​notch 311. After adjustment, press baffle 344 and rotate lever 346 to lock it, achieving precise flow control. The sealing gasket 313 and the first pressure gasket 3443 ensure the device's airtightness, preventing ink leakage and improving operational convenience and practicality.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
