Description

Technical Field

[0001] This invention relates to the field of roller mill technology, specifically to an automatic roller wiping device for roller mills. Background Technology

[0002] A double-roll crusher (also known as a roller crusher) is a mechanical device that uses one or more pairs of opposing rotating rollers to crush or shape materials through extrusion and grinding. For example, in the production of battery electrodes, the double-roll crusher is a key piece of equipment for compacting the battery electrodes after the coating process. During the rolling process, the surfaces of the battery electrodes and the upper and lower rollers are pressed together with a very high degree of tightness, thereby achieving the rolling of the battery electrodes.

[0003] During the actual rolling process, due to complex physical effects, electrode residues inevitably remain on the surface of the rolls, especially for battery negative electrode sheets. Due to their material characteristics and process features, this adhesion is more pronounced. If the residues on the roll surface are not treated in time, the accumulation will gradually increase as production continues. Once it reaches a certain level, the subsequent rolling effect of the electrode sheets will be severely affected.

[0004] Currently, although there are roller wiping devices for wiping the surface of rolls, the location of the wiping devices is relatively fixed and the wiping effect is limited. At the same time, the method of wiping by scraping the surface of the roll with a scraper is prone to reduced wiping effect due to insufficient pressure or damage to the surface of the roll due to excessive pressure over a long period of time. Therefore, we propose an automatic roller wiping device for roll forming machines. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figures 1-7 The figure shows an automatic roller wiping device for a roller mill, which includes a frame 101. Two rotating shafts 102 are rotatably connected to the frame 101. Pressure rollers 103 are fixedly connected to the side walls of the two rotating shafts 102. The device also includes a cleaning mechanism disposed on the frame 101 for cleaning the two pressure rollers 103. The cleaning mechanism includes a first T-shaped rod 201 and a second T-shaped rod 202 slidably connected within the frame 101. The first T-shaped rod 201 and the second T-shaped rod 202 are respectively connected to a first cleaning plate 203 and a second cleaning plate 204 via an extrusion assembly on the side near the pressure roller 103. The frame 101 is provided with a pushing assembly for pushing the first cleaning plate 203 and the second cleaning plate 204. The frame 101 is detachably connected to two collection boxes 205 opposite to two inner walls. The two collection boxes 205 are respectively located below the first cleaning plate 203 and the second cleaning plate 204. The frame 101 is provided with an adjustment assembly for adjusting the extrusion force of the second cleaning plate 204 on the pressure roller 103. It should be noted that, through the configuration of the cleaning mechanism, under the action of the driving and pushing components, the first cleaning plate 203 and the second cleaning plate 204 move laterally and reciprocally against the surface of the pressure roller 103 under the elastic action of the squeezing component, thereby improving the cleaning effect on the surface of the pressure roller 103. Furthermore, the first cleaning plate 203 and the second cleaning plate 204 wipe and clean the surface of the pressure roller 103 in sequence, thereby realizing a multi-stage cleaning operation on the pressure roller 103 and further improving the cleaning effect on the pressure roller 103.

[0022] Please see Figure 5 and Figure 6 The extrusion assembly shown in the figure includes an extrusion frame 404 fixedly connected to the first T-shaped rod 201 on the side near the first cleaning plate 203. An extrusion plate 401 is slidably connected inside the extrusion frame 404. A square plate 403 is connected to the side of the extrusion plate 401 near the first cleaning plate 203 by multiple springs 402. The side of the first cleaning plate 203 away from the pressure roller 103 is connected to the square plate 403. It should be noted here that the extrusion assembly is configured to ensure that the first cleaning plate 203 and the second cleaning plate 204 abut against the surface of the pressure roller 103.

[0023] Please see Figure 4 and Figure 5 The push assembly shown in the figure includes a fixed tube 301 fixedly connected to the side wall of the frame 101, a push plate 302 slidably connected to the fixed tube 301, one end of the first T-shaped rod 201 connected to the push plate 302, and a push rod 303 fixedly connected to the side of the push plate 302 away from the first T-shaped rod 201. The frame 101 is provided with a drive assembly for driving the push rod 303. It should be noted here that by setting up the push component, it is easy to achieve reciprocating pushing of the first cleaning plate 203 and the second cleaning plate 204.

[0024] Please see Figure 4 The drive assembly shown in the figure includes a first L-shaped plate 501 fixedly connected to the side of the frame 101 near the push rod 303. The first L-shaped plate 501 is rotatably connected to a worm gear 502. The worm gear 502 is engaged with a worm wheel 503. The worm wheel 503 is connected to the side wall of the first L-shaped plate 501 through an L-shaped support rod. The side of the worm wheel 503 near the push rod 303 is connected to a drive plate 504 through a connecting pin. The end of the drive plate 504 away from the worm wheel 503 is hinged to the push rod 303. It should be noted here that the configuration of the drive component facilitates the reciprocating movement of the pusher plate 302.

[0025] Please see Figure 4In the figure, a second L-shaped plate 505 is fixedly connected to the side of the frame 101 near the first L-shaped plate 501. A rotating rod 507 is rotatably connected to the side of the second L-shaped plate 505 near the frame 101. The rotating rod 507 is connected to the rotating shaft 102. Two transmission belts 506 are sleeved on the side wall of the rotating rod 507. One of the two transmission belts 506 is connected to the worm gear 502 near the side of the first T-shaped rod 201. The other of the two transmission belts 506 is connected to the worm gear 502 near the side of the second T-shaped rod 202 through a transmission ratio conversion component. It should be noted that by using the rotating rod 507 and the transmission belt 506, the rotation of the pressure roller 103 enables the reciprocating pushing of the first cleaning plate 203 and the second cleaning plate 204, thereby reducing the number of power equipment used and lowering the cost of cleaning the pressure roller 103.

[0026] Please see Figure 4 and Figure 7 The transmission ratio conversion assembly shown in the figure includes a conversion tube 601 fixedly connected to one end of the worm gear 502 near the frame 101. Multiple U-shaped conversion plates 602 are arranged in a ring array around the conversion tube 601. The end of the transmission belt 506 away from the rotating rod 507 is sleeved on the side wall of each U-shaped conversion plate 602. The conversion tube 601 is provided with an adjustment assembly for adjusting the spacing between each U-shaped conversion plate 602. It should be noted here that the transmission ratio conversion component is used to adjust the reciprocating frequency of the second cleaning plate 204.

[0027] Please see Figure 4 and Figure 7 The adjustment assembly shown in the figure includes a double-threaded rod 701 rotatably connected inside the conversion tube 601. Two D-shaped adjustment plates 702 are threadedly connected to the side wall of the double-threaded rod 701. The inner wall of the conversion tube 601 is matched with the two D-shaped adjustment plates 702. Multiple rectangular plates 703 are hinged to the opposite side of the two D-shaped adjustment plates 702. The ends of each rectangular plate 703 that are far apart from each other are connected to each U-shaped conversion plate 602. A motor 704 is provided on one of the two first L-shaped plates 501 near the conversion tube 601. The output end of the motor 704 is connected to the double-threaded rod 701 through an output rod. It should be noted here that by adjusting the settings of the components, it is convenient to move the various U-shaped transformation plates 602 closer to or further away from each other.

[0028] It is worth noting that during the process of changing the transmission ratio of the conversion tube 601 by moving the various U-shaped conversion plates 602 closer to or further away from each other, the side wall of the frame 101 is provided with a tension adjuster for adjusting the tension of the transmission belt 506, which is not shown in the figure here.

[0029] Please see Figure 5 and Figure 6 The adjustment assembly shown in the figure includes an adjustment tube 801 disposed on the side of the frame 101 near the conversion tube 601. The end of the adjustment tube 801 away from the frame 101 passes through the second T-shaped rod 202 and is connected to the extrusion frame 404. The end of the conversion tube 601 near the adjustment tube 801 is fixedly connected to the mounting tube 802. The end of the adjustment tube 801 away from the extrusion frame 404 is connected to the mounting tube 802 through a corrugated pipe. A piston 803 is slidably connected inside the mounting tube 802. It should be noted that by adjusting the component settings, the squeezing force on the second cleaning plate 204 is increased, which in turn increases the surface squeezing force of the second cleaning plate 204 on the pressure roller 103, thereby improving the wiping force on the surface of the pressure roller 103.

[0030] Please see Figure 5 and Figure 7 In the figure, the two D-shaped adjustment plates 702 are arranged in a ring array on the side near the piston 803, and each connecting rod 804 is connected to the piston 803 at the end away from the D-shaped adjustment plate 702. It should be noted that the connecting rod 804 facilitates the movement of the D-shaped adjusting plate 702, allowing the gas in the mounting tube 802 to be pushed from the adjusting tube 801 into the extrusion frame 404.

[0031] Please see Figure 2 and Figure 3 The collection box 205 located below the second cleaning plate 204 in the figure is equipped with a detection component for detecting the surface of the pressure roller 103. The detection component is fixedly connected to the support plate 901 on the side of the collection box 205 away from the second cleaning plate 204. The support plate 901 is equipped with an image sensor 902. The detection end of the image sensor 902 is set opposite to the pressure roller 103. It should be noted here that the detection component is set up to facilitate the detection of the surface of the pressure roller 103 after being wiped and cleaned by the first cleaning plate 203, thereby providing data reference for whether the second cleaning plate 204 needs to be adjusted.

[0032] Working principle: During the rotation of the pressure roller 103, the two pressure rollers 103 are driven to rotate in opposite directions by a rotating motor (not shown in the figure). The two opposing pressure rollers 103 compact the battery electrode sheet after the coating process. During the operation of the pressure roller 103, the two transmission belts 506 are driven to rotate synchronously through the rotating rod 507. During the rotation of the two transmission belts 506, the meshing transmission action of the two sets of worm gears 503 and worm 502 drives the two drive plates 504 to rotate. As the two drive plates 504 rotate in a circle around the worm gears 503, they apply a reciprocating pushing force to the push rod 303, which in turn drives the push plate 302 at one end of the push rod 303 to move reciprocally within the fixed tube 301. During the reciprocating movement of the two push plates 302 within the fixed tube 301, the first T-shaped rod 201 and the second T-shaped rod 202 will be driven to reciprocate, thereby driving the first cleaning plate 203 and the second cleaning plate 204 to reciprocate on the surface of the pressure roller 103 through the extrusion assembly. This allows the first cleaning plate 203 and the second cleaning plate 204 to move laterally reciprocating against the surface of the pressure roller 103 under the elastic action of the extrusion assembly, thus improving the cleaning effect on the surface of the pressure roller 103. Furthermore, the first cleaning plate 203 and the second cleaning plate 204 wipe and clean the surface of the pressure roller 103 in sequence, thereby realizing a multi-stage cleaning operation on the pressure roller 103. At the same time, by utilizing the rotation of the pressure roller 103, the first cleaning plate 203 and the second cleaning plate 204 are reciprocated and pushed by the drive assembly and the push assembly, thereby reducing the number of power equipment used and lowering the cost of cleaning the pressure roller 103. Furthermore, during the multi-stage cleaning process of the pressure roller 103 surface, the image sensor 902 between the first cleaning plate 203 and the second cleaning plate 204 is used to detect the surface of the pressure roller 103. When large pieces of debris still remain on the surface of the pressure roller 103 after the first cleaning plate 203 has finished cleaning, the double-ended threaded rod 701 can be rotated by the motor 704. During the rotation of the double-ended threaded rod 701, the threaded engagement between the double-ended threaded rod 701 and the two D-shaped adjusting plates 702, as well as the guiding action of the conversion tube 601, will push... The two D-shaped adjusting plates 702 move away from each other. During this movement, the rectangular plates 703 on the same side rotate closer together, which in turn causes the U-shaped changing plates 602 around the changing tube 601 to move closer together. This changes the transmission ratio between the rotating rod 507 and the changing tube 601, increasing the rotation speed of the worm gear 502 at one end of the changing tube 601. This, in turn, increases the reciprocating speed of the pushing plate 302 within the fixed tube 301, thereby increasing the speed of the second cleaning plate 204 on the pressure roller 103. The increased reciprocating speed of the surface increases the frequency of wiping the surface of the pressure roller 103. As the two D-shaped adjusting plates 702 move further apart, the connecting rods 804 push the piston 803 to slide within the mounting tube 802. Under the squeezing action of the piston 803, the gas in the mounting tube 802 is pushed from the adjusting tube 801 into the squeezing frame 404. The pressure then causes the squeezing plate 401 to move closer to the second cleaning plate 204, thus squeezing the spring 402. The change in the elastic force of the spring 402 further compresses the spring. The pressure applied to the second cleaning plate 204 is increased, which in turn increases the surface pressure of the second cleaning plate 204 on the pressure roller 103. This enhances the wiping force on the surface of the pressure roller 103. As a result, with the increased frequency and pressure of the reciprocating wiping of the pressure roller 103 by the second cleaning plate 204, the wiping effect of the pressure roller 103 is improved. This achieves the adjustability of the wiping frequency and pressure of the second cleaning plate 204 on the pressure roller 103, thereby reducing the risk of reduced wiping effect due to insufficient clamping force or damage to the surface of the pressure roller 103 due to excessive clamping force over a long period of time.
