Description

Technical Field

[0001] The present application relates to the technical field of milling equipment, and particularly to a milling equipment for plate roller processing. Background Art

[0002] As a key component in the printing and packaging industries, the processing precision of a plate roller directly affects the printing quality. Currently, the plate roller processing technologies mainly include methods such as turning, grinding, and milling. Among them, for the milling processing of plate rollers, a milling machine tool is often used.

[0003] For a milling machine tool used for plate roller processing, before processing, the plate roller needs to be installed and fixed on the fixture of the milling machine tool. Then, the machine tool is started, and then the milling cutter mills the plate roller. During milling, a coolant spray pipe arranged adjacent to the milling cutter on the machine tool will spray coolant towards the milling cutter to cool and lubricate the position where the milling cutter mills the plate roller. The machine tool is also provided with a recycling box for recycling the coolant and the debris generated during milling. A water pump is arranged in the recycling box for pumping the recycled coolant and transporting it to the coolant spray pipe to achieve the circulation of the coolant.

[0004] However, during the circulation of the coolant, in order to ensure the timely supply of the coolant and reduce the possibility of coolant overflow during filtration, the filter screen arranged in the recycling box can only filter debris with larger volumes. Some debris with smaller volumes are likely to continue to circulate with the coolant. At this time, when the coolant impacts the milling position of the milling cutter, it is likely to accelerate the wear rate of the milling cutter and affect the processing precision of the plate roller. Summary of the Invention

[0005] In order to improve the milling precision of the plate roller, the present application provides a milling equipment for plate roller processing.

[0006] The present application provides a milling equipment for plate roller processing, adopting the following technical solutions: A milling equipment for plate roller processing includes a machine body. The machine body is provided with a collection box. The collection box is provided with a collection groove. A circulation pump is arranged in the collection box. The circulation pump is provided with a transmission pipe communicated with the coolant spray pipe; A filter hopper is arranged in the collection box and located at the notch of the collection groove; A filter box is arranged at the bottom of the filter hopper. An accommodation groove is formed in the filter box. A water outlet communicating with the accommodation groove is formed at the bottom of the filter box; A filter roller is arranged in the filter box and located in the accommodation groove. The filter roller includes a roller body and a roller shaft. The roller shaft is fixedly connected with the roller body and coaxially arranged. The roller shaft is rotatably connected to the filter box; A roller groove extending circumferentially is formed inside the roller body. A plurality of power blades are evenly spaced along the circumferential direction on the outer peripheral side of the roller shaft. A filtering cavity is formed by enclosing between the power blades, the roller shaft and the roller body. A plurality of filtering holes communicating with the filtering cavity are evenly spaced on the outer peripheral side of the roller body. A filter cloth is wrapped around the outer peripheral side of the roller body. A connecting ring is rotatably arranged on the roller body and coaxially. A drain port is arranged at the bottom of the filtering hopper. A connecting pipe is arranged between the filtering hopper and the connecting ring. The connecting pipe communicates with the drain port and the filtering cavity. The bottom pipe orifice of the connecting pipe faces the side of the power blade away from the roller shaft.

[0007] By adopting the above technical solution, the filtering hopper can collect large particle debris separated from the coolant, while the filtering roller further finely filters the coolant. After the coolant enters the filtering cavity through the connecting pipe, the power blade drives the filtering roller to rotate under the action of the fluid. The filter cloth and the filtering holes effectively block small particle debris, reducing its circulation to the position of the milling cutter with the coolant, thereby reducing the wear of the milling cutter, improving the processing accuracy of the plate roller and extending the service life of the equipment. At the same time, when the filtering roller rotates, a centrifugal force is formed to accelerate the filtering speed of the coolant. And the filtered coolant is re-transported to the coolant spray pipe through the water outlet and the circulation pump to ensure the continuous supply and recycling of the coolant.

[0008] Optionally, the roller body is provided with partition plates that slide in the filtering cavity and correspond one by one. The circumferential side wall of the partition plate is slidably connected with the circumferential side wall of the filtering cavity. The roller body is provided with a driving assembly. When the roller shaft rotates, the driving assembly drives the partition plate to move axially in a reciprocating manner. A water passing port is formed on the partition plate. A plugging plate for plugging the water passing port is slidably connected to the partition plate. The roller body is provided with a control assembly. When the partition plate slides away from the connecting pipe, the control assembly controls the plugging plate to plug the water passing port. When the partition plate slides towards the connecting pipe, the control assembly controls the plugging plate to open the water passing port.

[0009] By adopting the above technical solution, the partition plate moves axially in a reciprocating manner in the filtering cavity, which can effectively divide the space in the filtering cavity, so that the coolant is processed in zones during the filtering process. When the partition plate slides away from the connecting pipe, the partition plate squeezes the coolant, thereby improving the filtering efficiency. When the partition plate slides towards the connecting pipe, the plugging plate opens the water passing port to allow the coolant to pass through, realizing the orderly flow and efficient filtering of the coolant.

[0010] Optionally, the driving assembly includes a reciprocating lead screw, a driving block and a driving strip. The reciprocating lead screw is arranged inside the roller shaft and coaxially, the reciprocating lead screw rotates relative to the roller shaft, and the reciprocating lead screw is connected to the filter box; The driving block is threadedly connected to the outer peripheral side of the reciprocating lead screw, and the driving block axially slides inside the roller shaft; Both ends of the driving bar are respectively connected to the driving block and the partition plate, and the roller shaft is provided with a driving hole extending axially and for the driving bar to slide.

[0011] By adopting the above technical solution, the reciprocating lead screw in the driving assembly cooperates with the driving block to realize the cyclic reciprocating motion of the partition plate along the axis. Specifically, the design that the reciprocating lead screw rotates relative to the roller shaft ensures the stability and reliability of power transmission; the driving block is threadedly connected to the outer peripheral side of the reciprocating lead screw and can perform precise axial displacement when the lead screw rotates; the driving bar transmits the motion of the driving block to the partition plate, thereby driving the partition plate to slide in the filter cavity.

[0012] Optionally, strip-shaped baffles with bellows structures are respectively arranged on the opposite sides of the driving bar, one side of the strip-shaped baffle far from the driving bar is connected to the hole wall of the driving hole, and the strip-shaped baffle is in sliding contact with the hole wall of the driving hole.

[0013] By adopting the above technical solution, when the driving bar slides in the driving hole, the strip-shaped baffle can effectively reduce the number of debris entering the driving hole.

[0014] Optionally, the control assembly includes an upper control column, a lower control column, control teeth and sliding teeth; The sliding teeth are arranged on the blocking plate, a sliding groove for the sliding teeth to slide along the radial direction of the roller body is formed on the partition plate, the control teeth are arranged on the partition plate and located in the sliding groove, and there are multiple control teeth which are evenly arranged up and down; The control teeth are meshed with the sliding teeth, and the control teeth slide on the control teeth; The upper control column is arranged on the wall of the filter cavity, the partition plate is provided with an upper control hole for the upper control column to insert, and the blocking plate is inclined to be provided with an upper control surface aligned with the upper control column; When the upper control column passes through the upper control hole and slides on the upper control surface, the blocking plate slides downward and blocks the water passing port; The lower control column is arranged on the wall of the filter cavity, and the bottom of the blocking plate and the side far from the connecting pipe are inclined to be provided with a lower control surface aligned with the lower control column; When the lower control column slides on the lower control surface, the blocking plate slides upward and opens the water passing port.

[0015] By adopting the above technical solutions, the control component can precisely control the opening and closing actions of the plugging plate on the water passage opening. Specifically, the meshing design of the sliding teeth and the control teeth maintains the state of the plugging plate. The cooperation between the upper control column and the upper control surface further ensures that the plugging plate can stably block the water passage opening at a specific position; while the cooperation between the lower control column and the lower control surface ensures that the plugging plate can reliably open the water passage opening at another specific position, guaranteeing the normal flow of water.

[0016] Optionally, a transmission port is provided on the plugging plate, and a water filter cloth for plugging the transmission port is provided on the plugging plate.

[0017] By adopting the above technical solutions, a transmission port is provided on the plugging plate and a water filter cloth is provided. When the partition plate squeezes the coolant, the coolant flows toward the side of the partition plate close to the connecting pipe, improving the filtering speed of the coolant.

[0018] Optionally, a discharge groove communicating with the filtering cavity and away from the connecting pipe is provided on the roller shaft. The discharge grooves correspond to the filtering cavities one by one. An opening and closing plate is slidably connected to the roller shaft, and a power spring for driving the opening and closing plate to block the notch of the discharge groove is provided on the roller shaft; Connecting teeth partially protruding into the filtering cavity are provided on the opening and closing plate, and a pushing column is provided on the partition plate. When the partition plate passes through the connecting teeth, the pushing column slides on the connecting teeth; When the partition plate returns toward the connecting pipe, the pushing column pushes the connecting teeth, driving the opening and closing plate to open the notch of the discharge groove. Until the connecting teeth abut against the groove wall of the discharge groove, the pushing column slides past the connecting teeth.

[0019] By adopting the above technical solutions, when the debris in the filtering cavity accumulates to a certain extent, the reciprocating movement of the partition plate can be used to automatically open the notch of the discharge groove, discharging the debris to the outside, effectively reducing the excessive accumulation of debris in the filtering cavity, thereby reducing the possibility of affecting the filtering effect. At the same time, the opening and closing plate can automatically reset under the action of the power spring to block the notch of the discharge groove, ensuring that the coolant does not leak and maintaining the normal operation of the equipment. In addition, this design does not require an additional power device, and the discharge of debris can be achieved by means of the movement of the partition plate, simplifying the structure and reducing energy consumption.

[0020] Optionally, a debris box located in the receiving groove is provided on the side wall of the filtering box. A debris groove is provided in the debris box. The roller shaft is rotatably connected to the debris box and extends into the debris groove on the side away from the connecting pipe; The discharge groove penetrates through the roller shaft to communicate with the debris groove, and a guiding surface extending obliquely downward toward the debris groove is provided on the groove wall of the discharge groove away from the notch.

[0021] By adopting the above technical solution, a debris box is provided on the side wall of the filtering box. A debris groove is formed in the debris box. The roller shaft is rotatably connected to the debris box and extends into the debris groove. The discharge groove penetrates through the roller shaft and is connected to the debris groove, and the wall of the discharge groove is provided with a downwardly inclined guiding surface. This design can effectively guide the filtered debris to smoothly enter the debris groove for collection, reduce the possibility of debris remaining or blocking during the discharge process, thereby reducing the possibility of debris re-mixing into the coolant, improving the purity of the coolant, further reducing the wear of the milling cutter, and enhancing the precision and efficiency of plate roller processing.

[0022] Optionally, a brush is provided on the side of the partition plate away from the connecting pipe. There are a plurality of the brushes evenly spaced along the extending trajectory of the edge of the partition plate, and the brushes are in sliding contact with the wall of the filtering cavity.

[0023] By adopting the above technical solution, a brush is provided on the side of the partition plate away from the connecting pipe. The brushes are evenly spaced along the extending trajectory of the edge of the partition plate and are in sliding contact with the wall of the filtering cavity. This design can effectively reduce the amount of debris remaining on the wall of the filtering cavity, thereby improving the filtering quality of the coolant, reducing the wear of the milling cutter caused by small debris circulating with the coolant, and enhancing the precision of plate roller processing.

[0024] In summary, the present application includes at least one of the following beneficial effects: 1. The filtering hopper can collect large particle debris separated from the coolant, while the filtering roller further finely filters the coolant. After the coolant enters the filtering cavity through the connecting pipe, the power blade drives the filtering roller to rotate under the action of the fluid.

Detailed implementation mode

[0027] The following will further elaborate on this application in conjunction with the attached Figures 1-5 drawings.

[0028] An embodiment of this application discloses a milling device for plate roller processing. Refer to Figure 1 , the milling device includes a machine body 1. A milling space is formed inside the machine body 1. The machine body 1 is provided with a fixture and a milling cutter located in the milling space. The plate roller workpiece to be processed is installed and fixed in the milling space through the fixture. During processing, the machine body 1 drives the milling cutter to rotate, and then the milling cutter mills the plate roller workpiece to be processed. A coolant spray pipe adjacent to the milling cutter is also arranged inside the machine body 1. During use, the coolant spray pipe sprays coolant towards the position where the milling cutter mills the plate roller workpiece to cool and lubricate the milling position. The milling of the plate roller workpiece by the machine body 1 is prior art, so it will not be elaborated here.

[0029] Refer to Figure 1 And Figure 2, a liquid outlet is provided at a position on the side wall of the machine body 1 near the bottom. The liquid outlet is communicated with the milling space. The coolant in the milling space and the chips generated during milling are discharged through the liquid outlet. The machine body 1 is detachably fixed with a collection box 2. The collection box 2 is provided with a collection groove 21. The notch of the collection groove 21 is located at the top of the collection box 2. The collection box 2 is located below the liquid outlet and the notch of the collection groove 21 is aligned with the liquid outlet. During use, the coolant and chips discharged from the liquid outlet enter the collection groove 21 through the notch of the collection groove 21. A circulation pump 22 is installed and placed in the collection box 2. The water outlet side of the circulation pump 22 is fixedly connected with a transmission pipe 23. The side of the transmission pipe 23 away from the circulation pump 22 is connected to the machine body 1 and is communicated with the coolant spray pipe. When the circulation pump 22 is started, the coolant in the collection groove 21 is extracted and transmitted to the universal roller through the transmission pipe 23, and the recycling of the coolant can be realized.

[0030] The milling equipment further includes a filter hopper 3 and a filter box 4. The filter hopper 3 has a frustum of a pyramid structure. The filter hopper 3 is installed and placed at the bottom of the filter box 4 and at the position of the notch of the collection groove 21. The bottom part of the filter hopper 3 protrudes into the collection groove 21. A drain port 31 is formed at the bottom of the filter hopper 3. A coarse filter screen is provided at the bottom of the filter hopper 3, and the coarse filter screen covers the drain port 31. During use, the coarse filter screen coarsely filters the chips in the coolant, enabling the coolant to be discharged quickly and reducing the possibility of the coolant overflowing from the filter hopper 3.

[0031] The filter box 4 is installed and fixed at the bottom of the filter hopper 3. An accommodation groove 41 is provided in the filter box 4. A connecting pipe 32 is fixedly connected to the top box wall of the filter box 4. The top of the connecting pipe 32 is connected and fixed to the bottom of the filter hopper 3, and the connecting pipe 32 is communicated with the drain port 31. The coolant coarsely filtered in the filter hopper 3 flows into the accommodation groove 41 through the connecting pipe 32. A water outlet 42 is provided at the bottom of the filter box 4. The water outlet 42 is communicated with the accommodation groove 41. The coolant in the accommodation groove 41 flows out through the water outlet 42.

[0032] See Figure 2 And Figure 3 , the milling equipment further includes a filter roller 5. The filter roller 5 is arranged in the filter box 4 and is located in the accommodation groove 41. The filter roller 5 includes a roller body 6 and a roller shaft 7. The diameter of the roller body 6 is larger than the diameter of the roller shaft 7; the roller shaft 7 is fixedly connected to the roller body 6 and is coaxially arranged. The length of the roller shaft 7 is greater than the length of the roller body 6. The roller shaft 7 is rotatably connected to the opposite vertical box walls of the filter box 4.

[0033] A roller groove 61 is formed inside the roller body 6, and the roller groove 61 extends circumferentially. A power blade 71 is fixedly connected to the outer peripheral side of the roller shaft 7. There are multiple power blades 71, which are evenly spaced circumferentially. A filtering cavity 51 is formed by enclosing between the power blade 71, the roller shaft 7 and the roller body 6. Filtering holes 62 are formed on the outer peripheral side of the roller body 6. The filtering holes 62 communicate with the filtering cavity 51. There are multiple filtering holes 62, which are evenly spaced. A filter cloth 63 is wrapped around the outer peripheral side of the roller body 6, and the mesh holes of the filter cloth 63 are fine.

[0034] The milling equipment further includes a connecting ring 64. The connecting ring 64 is rotatably arranged on the roller body 6 and coaxially arranged. The connecting ring 64 is located at a position close to the end of the roller body 6. The side of the power blade 71 away from the roller shaft 7 is slidably connected to the inner peripheral side wall of the connecting ring 64. A connecting pipe 32 is fixedly connected to the connecting ring 64. At this time, the connecting pipe 32 restricts the rotation of the connecting ring 64, and the connecting ring 64 and the roller body 6 rotate relative to each other. The side of the connecting pipe 32 away from the drain port 31 communicates with the filtering cavity 51, and the bottom pipe orifice of the connecting pipe 32 is directly opposite to the side of the power blade 71 away from the roller shaft 7. The coolant enters one of the connected filtering cavities 51 through the connecting pipe 32, and then the coolant impacts the power blade 71, causing the roller body 6 and the roller shaft 7 to enter a rotating state. When until the next filtering cavity 51 rotates to communicate with the connecting pipe 32, at this time, the connecting pipe 32 sprays out the coolant to continue to impact the corresponding power blade 71; and the coolant in the filtering cavity 51 is filtered by the filter cloth 63 through the filtering holes 62, and then flows into the receiving groove 41, reducing the number of debris in the coolant flowing into the receiving groove 41, and when the roller body 6 and the roller shaft 7 rotate, a centrifugal force is formed, increasing the amount of coolant flowing into the receiving groove 41.

[0035] The roller body 6 is provided with a partition plate 65. The partition plate 65 slides in the filtering cavity 51. There are multiple partition plates 65, which correspond to the filtering cavity 51 one by one. The circumferential side walls of the partition plate 65 are respectively slidably connected to the circumferential side walls of the filtering cavity 51. The roller body 6 is provided with a driving assembly 8. When the roller shaft 7 rotates, the driving assembly 8 drives the partition plate 65 to move axially in a reciprocating manner.

[0036] The driving assembly 8 includes a reciprocating lead screw 81, a driving block 82 and a driving bar 83. The reciprocating lead screw 81 is arranged inside the roller shaft 7. The reciprocating lead screw 81 is coaxially arranged with the roller shaft 7. The reciprocating lead screw 81 rotates relative to the roller shaft 7. One end of the reciprocating lead screw 81 is located inside the roller shaft 7, and the other end extends out of the roller shaft 7 and is fixedly connected to the vertical box wall on one side of the filtering box 4.

[0037] The driving block 82 is threadedly connected to the outer peripheral side of the reciprocating lead screw 81. The driving block 82 axially slides within the roller shaft 7, and the end face of the driving block 82 is square. Both ends of the driving bar 83 are fixedly connected to the driving block 82 and the partition plate 65 respectively. There are multiple driving bars 83 which correspond to the partition plate 65 one by one. The roller shaft 7 is provided with a driving hole 72 extending axially, and the driving bar 83 is slidably connected to the driving hole 72. When the roller shaft 7 rotates, the driving block 82 axially reciprocates and circulates within the roller shaft 7 under the action of the reciprocating lead screw 81. When the driving block 82 slides, the driving bar 83 drives the partition plate 65 to reciprocate and slide within the filtering cavity 51, and the coolant within the filtering cavity 51 is squeezed by the partition plate 65 to increase the outflow speed of the coolant from the filtering cavity 51.

[0038] Blocking bars 73 are respectively fixedly connected to the opposite sides of the driving bar 83. The blocking bars 73 are of bellows structure. The side of the blocking bar 73 away from the driving bar 83 is fixedly connected to the vertical side wall of the driving hole 72 facing the driving bar 83, and the vertical side walls on the opposite sides of the blocking bar 73 are respectively slidably connected to the opposite vertical side walls of the driving hole 72. During use, the driving hole 72 is blocked by the blocking bars 73 to prevent debris from entering the driving hole 72.

[0039] A plurality of bristles 655 are fixedly connected to the side of the partition plate 65 away from the connecting pipe 32. The bristles 655 are evenly spaced along the extending trajectory of the edge of the partition plate 65, and the bristles 655 are in sliding contact with the wall of the filtering cavity 51. When the partition plate 65 slides, the bristles 655 clean the wall of the filtering cavity 51 to reduce the amount of debris remaining on the wall of the filtering cavity 51.

[0040] The partition plate 65 is provided with a water passing port 651, and a plugging plate 654 is slidably connected to the partition plate 65 along the directions of approaching and departing from the central axis of the roller shaft 7. When the partition plate 65 slides along the direction of approaching the central axis of the roller shaft 7, the partition plate 65 plugs the water passing port 651; when the partition plate 65 slides along the direction of departing from the central axis of the roller shaft 7, the partition plate 65 opens the water passing port 651.

[0041] See Figure 4 And Figure 5 A transmission port 6543 is provided on the plugging plate 654, and a water filtering cloth 6544 is fixedly connected to the plugging plate 654. The water filtering cloth 6544 plugs the transmission port 6543.

[0042] See Figure 3 And Figure 5 When the partition plate 65 slides in the direction away from the connecting pipe 32, the partition plate 65 not only squeezes the coolant out of the filtering holes 62, but also the coolant flows towards the side of the partition plate 65 close to the connecting pipe 32 after being filtered by the water filtering cloth 6544. At this time, the amount of debris in the coolant within the filtering cavity 51 on the side of the partition plate 65 close to the connecting pipe 32 is greatly reduced, which is beneficial to increasing the outflow speed of the coolant.

[0043] See Figure 2 and Figure 3 Figure 2 is provided with a control component. When the partition plate 65 slides away from the connecting pipe 32, the control component controls the plugging plate 654 to block the water through hole 651; when the partition plate 65 slides towards the connecting pipe 32, the control component controls the plugging plate 654 to open the water through hole 651.

[0044] The control component includes an upper control column 91, a lower control column 92, control teeth 93 and a sliding tooth 9. The sliding tooth 9 is fixedly connected to the plugging plate 654. A sliding groove 652 extending radially towards the roller body 6 is formed in the partition plate 65, and the sliding tooth 9 is slidably connected to the sliding groove 652. The control teeth 93 are fixedly connected to the partition plate 65, the control teeth 93 are located in the sliding groove 652, and there are multiple control teeth 93 which are evenly arranged up and down. The control teeth 93 are meshed with the sliding tooth 9. The control teeth 93 and the sliding tooth 9 respectively adopt a triangular tooth-shaped structure, and the control teeth 93 and the sliding tooth 9 are respectively made of materials with elastic deformation ability, such as plastic and rubber. When the plugging plate 654 slides up and down, the control teeth 93 slide on the control teeth 93.

[0045] The upper control column 91 is fixedly connected to the wall of the filtering cavity 51. The upper control column 91 is located at a position close to the connecting pipe 32, and the upper control column 91 corresponds to the plugging plate 654 one by one. The partition plate 65 is provided with an upper control hole 653 extending along the central axis direction of the roller shaft 7. When the partition plate 65 slides to the vertical wall of the filtering cavity 51 close to the connecting pipe 32, the upper control column 91 slides into the upper control hole 653. The plugging plate 654 is inclined to be provided with an upper control surface 6541. When the plugging plate 654 opens the water through hole 651, the upper control surface 6541 is aligned with the upper control hole 653. During the process that the upper control column 91 continuously slides into the upper control hole 653, the upper control column 91 slides on the upper control surface 6541. At this time, the upper control column 91 pushes the plugging plate 654 to slide downwards to block the water through hole 651.

[0046] The lower control column 92 is fixedly connected to the wall of the filtering cavity 51 on the side opposite to the upper control column 91. The bottom of the plugging plate 654 and the side far from the connecting pipe 32 are inclined to be provided with a lower control surface 6542. When the plugging plate 654 blocks the water through hole 651, the lower control surface 6542 is aligned with the lower control column 92. When the lower control column 92 slides towards the side far from the connecting pipe 32 until it is adjacent to the wall of the filtering cavity 51 far from the upper control column 91, the lower control column 92 slides on the lower control surface 6542. At this time, the lower control column 92 pushes the plugging plate 654 to slide upwards to open the water through hole 651.

[0047] The roller shaft 7 is provided with a discharge groove 74, the discharge groove 74 communicates with the filter chamber 51, and the discharge groove 74 is located at a position away from the connecting pipe 32, and the discharge groove 74 corresponds to the filter chamber 51 one by one. A closing plate 75 is slidably connected in the roller shaft 7, and the closing plate 75 corresponds to the discharge groove 74 one by one. A power spring 76 is installed in the roller shaft 7. One end of the power spring 76 abuts against the side wall of the closing plate 75 close to the connecting pipe 32, and the other end abuts against the roller shaft 7. When the power spring 76 elastically releases, it drives the closing plate 75 to slide towards the side away from the connecting pipe 32 to block the notch of the discharge groove 74.

[0048] A connecting tooth 751 is fixedly connected to the end surface of the closing plate 75 facing the notch of the discharge groove 74. The connecting tooth 751 has a triangular tooth-like structure. The part of the connecting tooth 751 away from the closing plate 75 protrudes into the filter chamber 51, and the connecting tooth 751 is made of a material with elastic deformation ability, such as plastic or rubber. A pushing column 656 is fixedly connected to the side of the partition plate 65 away from the connecting pipe 32. The pushing column 656 has an "L" shape. When the partition plate 65 slides close to the connecting tooth 751, the pushing column 656 slides on the connecting tooth 751, so that the side of the pushing column 656 away from the partition plate 65 can slide to the side of the connecting tooth 751 away from the connecting pipe 32.

[0049] When the side of the pushing column 656 away from the partition plate 65 slides to the side of the connecting tooth 751 away from the connecting pipe 32, the corresponding filter chamber 51 moves from below the roller shaft 7 to above the roller shaft 7; when the partition plate 65 slides back towards the connecting pipe 32, the pushing column 656 first abuts against the connecting tooth 751, and then when the partition plate 65 continues to slide, the pushing column 656 pushes the closing plate 75 to open the notch of the discharge groove 74, and the power spring 76 enters the elastic compression state until the connecting tooth 751 abuts against the groove wall of the discharge groove 74, at this time the pushing column 656 slides past the connecting tooth 751, and at this time the power spring 76 elastically releases to push the closing plate 75 to block the notch of the discharge groove 74. When the filter chamber 51 moves from below the roller shaft 7 to above the roller shaft 7 and the closing plate 75 opens the discharge groove 74, the debris in the corresponding filter chamber 51 falls into the discharge groove 74.

[0050] A debris box 43 is fixedly connected to the side wall of the filter box 4, and the debris box 43 is located in the receiving groove 41. A debris groove 44 is formed in the debris box 43, and a box door is hingedly installed on the outer wall of the debris box 43 to facilitate cleaning of the debris groove 44. The roller shaft 7 is rotatably connected to the debris box 43 and extends into the debris groove 44 on the side far from the connecting pipe 32. The discharge groove 74 penetrates the roller shaft 7 toward the side far from the connecting pipe 32, so that the discharge groove 74 is communicated with the debris groove 44. A guiding surface 77 is formed on the groove wall of the discharge groove 74 on the side far from the groove opening, and the guiding surface 77 extends obliquely downward toward the debris groove 44. The debris entering the discharge groove 74 slides into the debris box 43 along the guiding surface 77, and a water filter net is arranged at the bottom of the debris box 43. The coolant contained in the debris entering the debris groove 44 is filtered by the water filter net and then enters the receiving groove 41.

[0051] The implementation principle of a milling device for plate cylinder processing in an embodiment of the present application is as follows: During plate cylinder processing, the coolant in the machine body 1 first flows into the filter hopper 3 for filtering, and then the filtered coolant flows into the connecting pipe 32; then the coolant impacts the power blade 71 downward, causing the roller body 6 and the roller shaft 7 to enter a rotating state, and the filtered liquid overflows from the filter chamber 51 during the rotation of the roller body 6 and the roller shaft 7. Then the overflowed coolant is collected in the collection tank 21 and recycled by the circulation pump 22. At the same time, the debris in the filter chamber 51 enters the discharge groove 74 and then is discharged into the debris groove 44, reducing the amount of debris in the filter chamber 51.

[0052] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
