The application is described below with reference to specific embodiments in conjunction with the accompanying drawings:
as shown in fig. 1 to 4, an embodiment of the present application provides a grinding fluid paper filter, which includes a main body frame 200, a filter paper feeding member 300 fixed on the main body frame 200, a clamping and conveying assembly 400, a wringing assembly 500, and a driving mechanism 600.
A filter tank 210 is provided in the main body frame 200, and a top of the filter tank 210 is opened, and grinding fluid is injected into the filter tank from the opening.
Specifically, the filter tank 210 is a rectangular tank, and two side plates 211 are disposed in the main frame 200 and are opposite to each other, and the two side plates 211 constitute the filter tank 210.
The filter paper feeding member 300 is fixed to the main body frame 200 at one side of the filter tank 210, and the filter paper feeding member 300 is higher than the opening of the filter tank 210, the filter paper feeding member 300 is horizontally disposed, and both ends of the filter paper feeding member 300 are rotatably connected to the main body frame 200, the filter paper feeding member 300 is used for mounting the filter paper 100 which is not used in a roll, and the filter paper 100 is gradually unfolded by rotating the filter paper feeding member 300.
As shown in fig. 5, specifically, the filter paper feeding member 300 includes a first rotating shaft 310 and a first limiting member 320, where the two first limiting members 320 are circular plates, the two first limiting members 320 are spaced apart, and two ends of the first rotating shaft 310 respectively pass through the centers of the two first limiting members 320 and are relatively fixed with the first limiting members 320 by welding or a key connection manner. Of course, in some other embodiments, the first limiting member 320 may be a rectangular plate or other anisotropic plate. In addition, two first supports 220 disposed opposite to each other are fixed to the main body frame 200, and the two first supports 220 are disposed along the width direction of the main body frame 200. The top of the first supporting member 220 is provided with a first mounting groove 221 for supporting the end of the first rotating shaft 310, and both ends of the first rotating shaft 310 are respectively placed in the first mounting grooves 221 of the two first supporting members 220. The distance between the two first limiting members 320 is greater than or equal to the width of the filter paper 100 placed on the first rotating shaft 310, the linear distance between the outer side edge of the first limiting member 320 and the first rotating shaft 310 is greater than or equal to the thickness of the filter paper 100 wound on the first rotating shaft 310, so that the two first limiting members 320 limit the filter paper 100 to prevent the filter paper 100 from scattering, and the outer side walls of the two first limiting members 320 are respectively attached to the two first supporting members 220, so that the swing of the filter paper feeding member 300 is reduced, and the change of the relative position between the filter paper 100 and the filter tank 210 after the filter paper 100 enters the filter tank 210 is reduced. Because the openings of the first mounting grooves 221 are upward, when the filter paper 100 is mounted on the filter paper feeding member 300, the filter paper 100 can be rolled up and mounted only by directly taking out the filter paper feeding member 300, and after the rolling up and mounting are completed, the two ends of the first rotating shaft 310 are put into the two first mounting grooves 221, so that the filter paper 100 can be rapidly rolled up and mounted.
The pinch assembly 400 is secured within the filter tank 210 and the expanded end of the filter paper 100 enters the pinch assembly 400, which causes the filter paper to enter the filter tank 210. The nip assembly is capable of nipping the filter paper 100 and moving the filter paper 100 toward the other side of the main body frame 200.
Specifically, the pinch assembly 400 includes a first pinch roller 410 and a second pinch roller 420 positioned below the first pinch roller 410, both ends of the first pinch roller 410 are rotatably connected to the main body frame 200, and both ends of the second pinch roller 420 are also rotatably connected to the main body frame 200. The open end of the filter paper 100 passes through the space between the first pinch roller 410 and the second pinch roller 420, the first pinch roller 410 and the second pinch roller 420 clamp the upper surface and the lower surface of the filter paper 100 respectively, and the driving mechanism 600 is connected with the pinch assembly 400 and drives the second pinch roller 420 to rotate, so that the first pinch roller 410 and the second pinch roller 420 drive the filter paper 100 to move, and the function of conveying the filter paper 100 is realized. The pinching assembly 400 can pull the filter paper 100 and gradually spread the filter paper 100 on the filter paper feeding member 300 during pinching the filter paper 100, and no special driving device is required to be arranged on the filter paper feeding member 300. In this embodiment, the first pinch roller 410 and the second pinch roller 420 are rubber rollers, so as to provide greater friction force to the filter paper 100, and reduce the occurrence of slipping of the filter paper 100. Of course, in some other embodiments, other roller bodies of other materials having surfaces capable of providing sufficient friction to the filter paper 100 may be used for the first pinch roller 410 and the second pinch roller 420.
It should be noted that, the filter paper 100 passes through the filter tank 210 from two ends of the filter tank 210 in the length direction, and the filter paper 100 is a strip filter paper, the width of the filter paper 100 is greater than or equal to the width of the filter tank 210, so that two sides of the filter paper can be attached to the side plates 211 of the filter tank 210, after the filter paper 100 enters the filter tank 210, the filter paper 100 separates the filter tank 210 into an upper cavity above the filter paper 100 and a lower cavity below the filter paper 100, so that the grinding fluid entering the upper cavity must be filtered by the filter paper 100 before entering the lower cavity of the filter tank 210 through the filter paper 100, and impurities separated from the grinding fluid stay and are adsorbed on the upper surface of the filter paper 100 in the process of filtering the grinding fluid, and the filtered grinding fluid passes through the filter paper 100 to enter the lower cavity to be collected in a concentrated manner. When the filter paper 100 is larger than the width of the filter tank 210, both sides of the filter paper 100 in the width direction are tilted upward to improve the stability of the fitting of the filter paper 100 to the side plate 211.
The wringing assembly 500 is fixed on the main body frame 200 and located at the other side of the filter tank 210, so that the filter paper 100 can completely and transversely pass through the filter tank 210 and separate the filter tank 210, the wringing assembly 500 can wring the filter paper 100 which is filtered with grinding fluid and adsorbs a large amount of grinding fluid and impurities, and the redundant grinding fluid in the filter paper 100 is squeezed out, so that the filter paper 100 can not drip after passing through the wringing assembly 500, and the environmental pollution caused by grinding the drop landing surface in the process of carrying the waste filter paper 100 is reduced.
Specifically, the wringing assembly 500 includes a first wringing roller 510 and a second wringing roller 520 positioned below the first wringing roller 510. Both ends of the first wringing roller 510 are rotatably connected to the main body frame 200, and both ends of the second pinch roller 420 are also rotatably connected to the main body frame 200. When the filter paper 100 conveyed by the pinch assembly 400 passes through the space between the first squeezing roller 510 and the second squeezing roller 520, the first squeezing roller 510 presses the filter paper 100 on the second squeezing roller 520, the driving mechanism 600 is connected with the squeezing assembly 500 and drives the second squeezing roller 520 to rotate, so that the first squeezing roller 510 and the second squeezing roller 520 can drive the filter paper 100 to move when rotating, and simultaneously, a large amount of grinding fluid adsorbed in the filter paper 100 can be squeezed out through the roller surfaces of the first squeezing roller 510 and the second squeezing roller 520, so that the squeezed grinding fluid flows back into the filter tank 210 along the filter paper 100 under the action of gravity, the grinding fluid can be recovered, the loss of the grinding fluid is reduced, the filter paper after passing through the squeezing assembly 500 can not have the phenomenon of dripping, and the environmental pollution caused by the dripping of the ground in the process of moving the waste filter paper is avoided. In addition, the first wringing roller 510 can also press metal impurities on the surface of the filter paper 100 onto the filter paper 100 while squeezing out the grinding fluid, thereby avoiding the metal impurities from falling from the waste filter paper during the process of moving the waste filter paper. It should be noted that, the first wringing roller 510 and the second wringing roller 520 are rubber rollers to provide greater friction to the filter paper 100, so as to reduce slipping of the filter paper 100. Of course, in some other embodiments, other roll bodies of other materials having surfaces capable of providing sufficient friction to the filter paper 100 may be used for the first wringing roll 510 and the second wringing roll 520.
Through the grinding fluid paper filter, the grinding fluid can be filtered, meanwhile, the grinding fluid in the filter paper 100 can be extruded, the waste of the grinding fluid is reduced, and meanwhile, the ground environmental pollution caused by the ground drop of the grinding fluid can be avoided.
When the grinding fluid paper filter is used, the grinding fluid paper filter is installed above a preset trench, and the lower end of the filter tank 210 faces the trench and is communicated with the trench, so that filtered grinding fluid can flow into a designated position through the trench. Of course, in some other embodiments, a pipe may be connected to the lower cavity of the filter tank 210 to drain the filtered grinding fluid into the finger position through the pipe.
As shown in fig. 5, further, the first nip roller is hinged to the main body frame 200 by the first connection member 411, so that the first nip roller can swing with respect to the main body frame 200 by the first connection member 411, thereby enabling the first nip roller to move toward or away from the second nip roller. When the first nip roller moves toward the second nip roller, the filter paper 100 can be pressed between the first nip roller and the second nip roller by the gravity of the first nip roller itself, thereby realizing the clamping of the filter paper 100. When the first clamping roller moves back to the second clamping roller under the action of external force, the first clamping roller and the second clamping roller are separated, and the gap between the first clamping roller and the second clamping roller is increased, so that the filter paper 100 can be conveniently passed through the gap between the first clamping roller and the second clamping roller when the filter paper 100 is replaced.
Specifically, the number of the first connectors 411 is two, one ends of the two first connectors 411 are respectively hinged to two ends of the first clamping roller, and the other ends of the two first connectors 411 are respectively hinged to the main body frame 200, so that the first clamping roller can be matched with the second clamping roller to clamp the filter paper 100, and the integral swing of the first clamping roller can be realized through the first connectors 411. Further, in this embodiment, the main body frame 200 is provided with a second supporting rod 230 protruding outwards, and the first connecting piece 411 is connected with the second supporting rod 230 through a pin shaft 231 to achieve hinging. The second pinch roller 420 is connected to the above-described driving mechanism 600 to rotate under the driving of the driving mechanism 600.
Further, a supporting mechanism for supporting the filter paper 100 is further disposed in the filter tank 210, the supporting mechanism is located between the pinch assembly 400 and the wringing assembly 500, and a supporting surface of the supporting mechanism is connected with the pinch assembly 400 and the wringing assembly 500, so that the filter paper 100 can be laid on the supporting mechanism after being discharged from the pinch assembly 400, and the supporting mechanism provides supporting force for the filter paper 100, so that the risk of tearing the filter paper 100 due to overweight grinding fluid is reduced.
Specifically, in this embodiment, the supporting mechanism includes a plurality of first supporting rollers 710, the axial direction of the first supporting rollers 710 is parallel to the axial direction of the filter paper feeding member 300, two ends of the first supporting rollers 710 are rotatably connected to two sides of the width direction of the filter tank 210, and the plurality of first supporting rollers 710 are sequentially arranged along the length direction of the filter tank 210, so that the lower surface of the filter paper 100 can be laid on the roller surface of the first supporting rollers 710, and the roller surfaces of the plurality of first supporting rollers 710 together form the supporting surface of the supporting mechanism.
Further, in this embodiment, the first support roller 710 is connected to the driving mechanism 600, so that the driving mechanism 600 can also drive the first support roller 710 to rotate, and the rotation direction of the first support roller 710 is the same as that of the second pinch roller 420, so that when the filter paper 100 moves on the support surface of the supporting mechanism, the contact area between the first support roller 710 and the filter paper 100 can be reduced through the circular roller surface, and the effect of reducing the friction force between the first support roller 710 and the lower surface of the filter paper 100 can be achieved, and meanwhile, the first support roller 710 can also play a role in conveying the filter paper 100 during the rotation process.
As shown in fig. 4, further, the plurality of support rollers are divided into a first roller group and a second roller group along the arrangement direction from the pinch assembly 400 to the wringing assembly 500, wherein the plurality of roller first support rollers 710 in the first roller group close to the pinch assembly 400 are positioned at the same horizontal level, so that the filter paper 100 is laid on the first support rollers 710 on the first roller group in a horizontal state, thereby enabling even a small amount of grinding fluid to be dispersed on the filter paper 100 in the horizontal state, and improving the filtering effect of the filter paper 100 on the grinding fluid; the heights of the first support rollers 710 in the second roller set close to the wringing assembly 500 are gradually increased, so that the filter paper 100 is laid on the first support rollers 710 on the second roller set in an inclined state, and the heights of the second support rollers 720 on part of the second roller set are higher than the liquid level of the grinding fluid injected into the filter tank 210, so that part of the grinding fluid in the filter paper 100 flows back into the filter tank 210 along the paper surface of the filter paper 100 in the process of lifting the filter paper 100 into the wringing assembly 500, and the primary water filtering of the filter paper 100 is realized.
Further, the heights of the first pinch roller 410 and the second pinch roller 420 are higher than the heights of the first roller set, so that the filter paper 100 is laid in the pinch assembly 400, the supporting roller mechanism and the wringing assembly 500, and a groove profile with a low middle and a high two ends can be formed, so that after being matched with the two sides of the filter groove 210 in the width direction, more grinding fluid can be contained, and meanwhile, a larger contact area is provided with the grinding fluid, so that the filtering efficiency of the grinding fluid paper filter on the grinding fluid is improved.
Further, the supporting mechanism further comprises a plurality of second supporting rollers 720, the diameter of the second supporting rollers 720 is smaller than that of the first supporting rollers 710, and the second supporting rollers 720 are parallel to the first supporting rollers 710 and are alternately arranged, so that one second supporting roller 720 is arranged at the gap between every two adjacent first supporting rollers 710, the filter paper 100 is supported by the second supporting rollers 720, a large gap formed between the two first supporting rollers 710 is changed into a small gap formed between the first supporting rollers 710 and the second supporting rollers 720, and the downward bending amplitude of the filter paper 100 is reduced, thereby being beneficial to improving the stable conveying of the filter paper 100. Especially, in the case that the tension applied to the filter paper 100 by the wringing roller is insufficient and the pinching assembly 400 is still pinching the filter paper 100, the phenomenon that the filter paper 100 is jammed due to the fact that the filter paper 100 is continuously squeezed into the gap between the adjacent first supporting rollers 710 under the continuous conveying action of the pinching assembly 400 after the filter paper 100 is bent downwards and falls from the gap between the adjacent two first supporting rollers 710 can be avoided.
Optionally, in this embodiment, the height of the highest point of the projection of the first support roller 710 on the side wall of the filter tank 210 is the same as the height of the highest point of the projection of the second support roller 720 on the side wall of the filter tank 210, where the highest point of the projection of the first support roller 710 on the side wall of the filter tank 210 is the highest supporting point of the first support roller 710 on the filter paper 100, and the highest point of the projection of the second support roller 720 on the side wall of the filter tank 210 is the highest supporting point of the second support roller 720 on the filter paper 100, so that the second support roller 720 and the first support roller 710 can support the filter paper 100 at the same height, and both the first support roller 710 and the second support roller 720 can simultaneously provide supporting force on the lower surface of the filter paper 100 when the filter paper 100 is in the straightened state.
Of course, in some other embodiments, the height of the highest supporting point of the second supporting roller 720 is between the height of the highest supporting point of the first supporting roller 710 and the height of the center of the first supporting roller 710, so that the second supporting roller 720 can achieve the effect of reducing the downward bending amplitude of the filter paper 100.
As shown in fig. 6, in this embodiment, an adjusting device for adjusting the pressing force of the first wringing roller 510 is connected to the first wringing roller 510, and the pressing force of the first wringing roller 510 on the filter paper 100 can be adjusted by the adjusting device, so as to achieve the purpose of adjusting the wringing effect of the wringing roller on the filter paper 100.
Specifically, the adjusting device includes a mounting seat 810, a bolt 820 and a spring 830, at least two through holes are formed in the upper surface of the mounting seat 810, the top of the main body frame 200 is provided with a threaded hole corresponding to the through hole, and the bolt 820 sequentially passes through the center of the spring 830 and the through hole and then is in threaded connection with the threaded hole, so that the compression amount of the spring 830 can be adjusted by screwing the bolt 820. The side wall of the mounting base 810 is provided with a connecting hole hinged with the first wringing roller 510, and if necessary, a bearing can be arranged in the connecting hole to reduce the resistance of the first wringing roller 510 when rotating relative to the mounting base 810. After the spring 830 compresses the mounting seat 810 on the top of the main body frame 200 under the action of self-elasticity, the roller surface of the first squeezing roller 510 contacts with the roller surface of the second squeezing roller 520, when the filter paper 100 enters between the first squeezing roller 510 and the second squeezing roller 520, because the two ends of the second squeezing roller 520 are rotationally connected with the main body frame 200 and the second squeezing roller 520 cannot move on a vertical plane, the filter paper 100 can enter between the first squeezing roller 510 and the second squeezing roller 520 after the first squeezing roller 510 is pushed away from the second squeezing roller 520, and therefore, after the compression amount of the spring 830 is adjusted by screwing the bolt 820, the downward pressure of the first squeezing roller 510 on the filter paper 100 can be adjusted, so that the adjustment of the squeezing effect of the filter paper 100 by the squeezing assembly 500 is achieved. The greater the amount of compression of the spring 830, the better the wringing effect of the wringer assembly 500 on the filter paper 100.

Specifically, the sprocket transmission mechanism includes at least one sprocket transmission unit formed by a chain 621 connected end to end and a plurality of sprockets 622 adapted to the chain 621, the sprocket 622 is fixed to the output shaft of the driving motor 610, the end of the second pinch roller 420, the end of the first support roller and the end of the second wringing roller 520, and the chain transmission connection among the output shaft of the driving motor 610, the second pinch roller 420, the first support roller and the second wringing roller 520 is realized by the engagement of the chain 621 and the sprocket 622.
Further, in the present embodiment, the number of sprocket driving units is multiple, and the output shaft of the driving motor 610, the second pinch roller 420, the first supporting rollers and the second wringing roller 520 are connected in a chain driving manner in pairs, so as to ensure that the second pinch roller 420, the first supporting rollers and the second wringing roller 520 can be driven to rotate synchronously when the output shaft of the driving motor 610 rotates. Specifically, a sprocket 622 is axially disposed on the output shaft of the driving motor 610 and the second wringing roller 520, and two sprockets 622 are axially disposed on the second pinch roller 420 and the plurality of support rollers, so that the output shaft of the driving motor 610, the second pinch roller 420, the plurality of first support rollers and the second wringing roller 520 are connected in a pairwise sequential chain transmission manner through a plurality of chains 621.
Preferably, the diameter of the second wringing roller 520 is larger than that of the second pinch roller 420 in the pinch assembly 400, so that the filter paper 100 has a larger contact area with the second wringing roller 520 when entering the wringing assembly 500, and the second wringing roller 520 provides a larger tension to the filter paper 100, so as to avoid the filter paper 100 from collapsing when walking, and further prevent the filter paper 100 from falling into the gap between the first support roller and the second support roller.
