Description

Technical Field

[0001] The invention relates to the field of paper belt filters, in particular to the field of paper feeding and changing of paper belt filters. Background Art

[0002] In the field of paper belt filter processing, paper belt filters are widely used in the purification, treatment and recycling of machine tool fluids such as cutting fluids or grinding fluids because they have higher filtration accuracy and a high degree of automation compared to other particle separation methods. Paper belt filters generally include a paper roll and a paper roll. When a roll of paper tape is used up, paper replacement begins. Paper replacement includes taking out the waste paper roll and putting a new paper roll on it. Generally, the paper roll is rewound by the motor-driven paper roll roller, which eventually winds the paper tape into a large paper roll. Existing paper belt filters are more complicated to replace waste paper rolls. The paper roll must be pulled out from the motor side to take out the paper roll. After the paper roll is wound to a certain thickness, the paper roll is difficult to remove. The paper roll needs to be pulled out manually, and the waste paper roll is generally very dirty, resulting in a poor on-site operation experience.

[0003] The existing paper tape filter uses a float liquid level detection to determine whether to feed the paper. When the liquid level above the filter rises to a certain value, it means that the paper tape is blocked. The liquid level detection signal is fed back to the winding motor, and the motor drives the paper collection roller to rotate and feed the paper. However, the float can only rise to a certain value before the paper can be fed. However, due to the different filtered liquids, some require low liquid levels to feed the paper, while others require high liquid levels to feed the paper. The existing paper tape filter cannot be applied to a variety of application scenarios. Summary of the invention

[0004] In order to solve the problem of replacing waste paper rolls and feeding paper in existing paper belt filters, the utility model provides a paper belt filter, in which a yielding mechanism is arranged on the side opposite to the power of the paper collection roller, so as to facilitate the removal of the waste paper roll and the replacement of the new paper roll, thereby improving the paper changing experience; a liquid level feedback device can be used to control the power to drive the paper collection roller to rotate and feed paper at different liquid levels.

DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0029] Embodiment 1:

[0030] like Figure 1 , Figure 2As shown, the paper tape filter comprises a paper roll 1, a paper roll 2, and a filter screen 7. A liquid inlet 8 is provided above the filter screen, a liquid storage cavity 9 is provided below the filter screen, and a liquid outlet 90 is provided in the liquid storage cavity. The paper tape 4 is placed above the filter screen 7 as a filter element.

[0031] like Figure 2 As shown, the paper tape 4 passes through the filter screen 7 from the paper unwinding roll 1, and then passes through the third shaft 31, and finally is wound on the paper receiving roller 20 to form the paper receiving roll 2. Figure 3 , both ends of the paper delivery roller 20 are fixed on the inner side of the frame 5, one end of the paper delivery roller 20 is connected to the power, and the power is fixed on the frame 5. On the opposite side to the power, the paper delivery roller 20 is provided with a yielding mechanism.

[0032] like Figures 3 - 6 As shown, the yielding mechanism includes a first rotating disk 21 and a first cover plate 22. The first rotating disk 21 is provided with a clamping block 210 for clamping and fixing the paper receiving roller 20. The yielding mechanism also includes a first shaft 23. The first shaft 23 passes through the first cover plate 22. The first cover plate 22 is provided with a limiting device for limiting the circumferential and axial movement of the first shaft 23. Figure 6 One side of the first shaft 23 is connected to the first end 231. The outer diameter of the first shaft 23 is larger than the first end 231. The first end 231 passes through the first rotating disk 21 and is threadedly connected to the first shaft 23 by a bolt 234. The first rotating disk 21 is rotatably connected to the first end 231. The other side of the first shaft 23 is connected to the second end 232. The second end 232 is used to pull out the first shaft 23. The second end 232 is provided with an annular groove to facilitate the first shaft 23 to be pulled out a certain distance by hand or tool. Figure 3 , the first cover plate 22 is fixedly connected to the frame 5. The first shaft 23 is provided with a protrusion 230, and the first cover plate 22 is provided with a groove for clamping the protrusion 230, and the groove includes an annular groove 221 and a strip groove 222 that are interconnected. The protrusion 230, the annular groove 221 and the strip groove 222 constitute a limiting device. When the first shaft 23 is inserted into the first cover plate 22, the protrusion 230 enters along the strip groove 222, and when the protrusion 230 slides to the annular groove 221, the first shaft 23 rotates a certain angle and is limited by both ends of the annular groove 221, thereby limiting the first shaft 23 in the axial direction and the circumferential direction.

[0033] like Figure 4 , Figure 5As shown in the figure, on the power side of the paper receiving roller 20, there are a second rotating disk 25, a second cover plate 26, and a power shaft 240. The power shaft 240 is fixed to the second rotating disk 25. The second cover plate 26 is provided with a through hole for the power shaft 240 to pass through, and the second cover plate 26 is fixedly connected to the machine frame 5. The power source 24 is fixed on the second cover plate 26, and the power shaft passes through the power source 24 and the second cover plate 26. The power side is also provided with a connecting plate 27. The connecting plate 27 is provided with a bolt hole 270 for abutting against the power shaft 240. The connecting plate 27 is bolted to the power source 24 to axially limit the power shaft 240. The second rotating disk 25 is provided with a clamping block (not shown in the figure) for fixing the paper receiving roller 20.

[0034] As Figure 2 , Figure 3 shown in the figure, an oil scraping plate 3 is further provided on the paper receiving roll 2. The upper end of the oil scraping plate 3 is provided with an oil scraping port 30. One end of the oil scraping plate is rotatably connected to the second shaft 31, and the other end of the oil scraping plate 3 is placed on the paper receiving roll 2. The paper tape passes from the paper feeding roll 1, passes through the filter screen 7, bypasses the second shaft 31, is abutted by the oil scraping port 30, and then wound around the paper receiving roller 20. When the paper receiving roller 20 rotates to receive paper, the oil scraping port 30 scrapes off the oil stains on the paper tape. The oil stains are collected by the waste oil tank along the outside of the oil scraping plate 3, and the waste paper tape is collected as solid waste, separating the waste oil and solid waste from the paper tape to reduce the amount of solid waste.

[0035] As Figure 1 , Figure 8 shown in the figure, the paper tape filter machine further includes a liquid level feedback device 6. The liquid level feedback device is arranged above the filter screen 7. The liquid level feedback device 6 includes a floating ball 60 and a support rod 61. The floating ball 60 is connected to the support rod 61, and the support rod 61 is connected to the third shaft 62. The third shaft 62 is rotatably connected to the connecting block 63, and the connecting block 63 is fixedly connected to the machine frame 5. The liquid level feedback device further includes a proximity switch 64. A trigger head 650 of the proximity switch is provided on the third shaft 62. The relative angle between the trigger head 650 and the third shaft 62 is adjustable. The trigger head 650 is fixed to the seat sleeve 65, and the seat sleeve 65 is threadedly connected to the third shaft 62. By rotating the thread, the angle between the trigger head 650 and the third shaft 62 is adjusted. Since the filter screen is inclined, the floating ball 60 is in a disc shape, and the lower bottom surface is placed on the inclined surface of the filter screen 7. When the paper tape is blocked by dirt, the liquid level above the filter screen rises, the floating ball 60 rises, driving the support rod 61 to rotate a certain angle around the third shaft 62, and the trigger head 620 rotates a certain angle along with the rotating shaft. When the trigger head 650 corresponds to the proximity switch, a signal is received and fed back to the PLC control system, and the control system controls the power source 24 to drive the paper receiving roller 20 to rotate and feed the paper.

[0036] Since the angle between the trigger head 650 and the third shaft 62 is adjustable, according to different liquid level requirements on site, by adjusting the angle, the rising height of the floating ball 60 can be adjusted, so as to realize paper feeding control at different liquid levels and be applicable to different application scenarios.

[0037] The working principle of the utility model paper belt filter:

[0038] like Figure 5 The blocks on the first rotating disk 21 and the second rotating disk 25 respectively clamp and fix the two ends of the paper receiving roller 20, and the first shaft 23 moves toward the paper receiving roller 20, driving the first rotating disk 21, and the power shaft 240 drives the second rotating disk 25 to abut the paper receiving roller from both ends. The first shaft 23 rotates a certain angle, so that the protrusion 230 is clamped into the annular groove 221, and the power 24 drives the second rotating disk 25 to rotate, driving the paper receiving roller 20 to rotate, and the protrusion 230 is restricted and positioned by the two ends of the annular groove 231, thereby realizing the axial and circumferential positioning of the first shaft 23.

[0039] When the paper tape is clogged by the filtered oil and fine particles, the liquid level above the filter screen 7 rises, the float 60 rises, the trigger head 650 receives a corresponding signal from the proximity switch 64, and the control system controls the power 24 to drive the paper delivery roller 20 to rotate and feed the paper.

[0040] like Figure 4 When the paper roll 1 is used up, the control system controls the motor to stop, and the first shaft 23 rotates a certain angle, so that the protrusion 230 rotates along the annular groove 221 to the position of the strip groove 222. The first shaft 23 is pulled out, and the first rotating disk 21 is driven to move a certain distance to the outside of the frame, so that the block 210 on the first rotating disk 21 is separated from the paper receiving roller 20. Figure 5 On the power side, unscrew the bolts between the connecting plate 27 and the power 24, and pull the power shaft 240 out for a distance. Separate the block on the second rotating disk 25 from the paper receiving roller 20. Figure 2 , and then the scraper plate 3 is rotated around the second axis 31 and pulled apart, and the paper receiving roll 2 rolls down by itself. The two middle paper receiving rolls 20 are retracted, and the paper tape is loosened, and the paper tape can be separated from the paper receiving roll 20. The paper receiving roll 2 can be easily rolled down without manual force, which improves the user's operating experience.

[0041] Embodiment 2:

[0042] like Figure 7 As shown, different from Example 1, the first shaft 23 in the yielding mechanism is a whole shaft, and a first end portion 231 is provided on one side, and a shaft shoulder 235 is provided on the first end portion 231. The first rotating disk 21 penetrates from one side of the first end portion 231 and abuts against the shaft shoulder 235. The stopper 233 positions the first rotating disk 21 axially, and a retaining spring groove is still provided on the first end portion 231, and the stopper 233 is a retaining spring.

[0043] On the other side of the first shaft 23, there is a second end portion 232. The second end portion 232 is provided with an annular groove, which is convenient for the hand or a tool to hold and clamp the first shaft 23 and pull it out a certain distance. The first shaft 23 is provided with a protruding portion 230. The protruding portion 230 can be a pin, and the first cover plate 22 is provided with a pin hole for cooperating with the pin.

[0044] The first end portion 232 passes through the central hole of the first cover plate 22, and the pin 230 is inserted to position the first shaft axially and circumferentially. When changing the receiving paper roll, the pin is pulled out, the second end portion 232 is clamped, and the first shaft 23 is pulled out a certain distance, driving the first rotating disk 21 to move out a certain distance, so that the first rotating disk 21 is separated from the paper receiving roller 20.

[0045] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
