Abstract
Description
Technical Field
[0001] This utility model relates to the field of calendering equipment, and more specifically, to an online roller cleaning mechanism and calendering equipment. Background Technology
[0002] In the lithium battery production process, rolling equipment is often used to roll and press materials. For example, lithium is rolled onto the electrode using calendering equipment, and the electrode is rolled and pressed using a rolling press.
[0003] During operation, dust from materials and the environment can easily adhere to the surface of the rollers, forming residues. These residues can cause additional pressure on the electrode sheets as the rollers continue to rotate, resulting in damage and secondary contamination.
[0004] To address this issue, the common methods currently used are either to use a scraper to remove residue or to use a lint-free cloth to wipe the roller. However, the scraper method is limited by the fact that the scraper cannot directly contact the roller surface, resulting in incomplete removal of residue. The lint-free cloth method is prone to residue buildup, which leads to residue re-adhesion onto the roller and requires frequent cloth replacement, impacting production efficiency. Utility Model Content
[0005] The purpose of this invention is to provide an online roller cleaning mechanism that can efficiently and thoroughly remove residues from the roller surface, thereby improving product quality and production efficiency.
[0006] Another objective of this invention is to provide a calendering device that has the advantages of better calendering effect and higher production efficiency.
[0007] The embodiments of this utility model provide a technical solution:

[0013] In an optional embodiment, a drive pulley is also included. Both the drive pulley and the brush drive are disposed on the outer surface of the dust collection cover, and the brush drive is connected to the brush through the drive pulley.
[0014] In an optional embodiment, the dust hood is further provided with a diluent connector, which is connected to the nozzle for delivering external diluent to the nozzle.
[0015] In an optional embodiment, the scraper is inclined at 15° to 45° relative to the axis of the roller body, and / or,

[0019] Compared to existing technologies, the online roller cleaning mechanism provided by this utility model, in practical applications, involves the roller surface extending into the opening of a dust collection hood. A negative pressure device is connected to the dust collection hood. During the roller's rotation, surface residues are initially scraped off by a scraper and then drawn away by the dust collection hood using negative pressure.

[0034] Example
[0035] Please refer to the following: Figure 1 and Figure 2 , Figure 1 The diagram shown is a schematic representation of the online roller cleaning mechanism 100 provided in this embodiment in practical application. Figure 2 As shown Figure 1 Sectional view of AA.
[0036] The online cleaning mechanism 100 for the roller body provided in this embodiment is used to clean the surface of the roller body 200 and remove surface residues. It is understood that the roller body 200 can be a calendering roller configured in a calendering equipment, or a pressure roller configured in a roll press, etc.
[0037] The online cleaning mechanism 100 for the roller includes a dust collection hood 110, and a scraper 120, a nozzle 130, a brush 140, and a felt 150 disposed within the dust collection hood 110. The dust collection hood 110 has an opening for the roller 200 to extend into. The scraper 120, the nozzle 130, the brush 140, and the felt 150 are arranged sequentially along the rotation direction of the roller 200. The scraper 120 is used to scrape off residues on the surface of the roller 200, the nozzle 130 is used to spray thinner onto the surface of the roller 200, the brush 140 is used to brush off residues on the surface of the roller 200, and the felt 150 is used to wipe off the thinner on the surface of the roller 200.
[0038] In practical applications, the dust collection hood 110 can be connected to an external negative pressure device. The roller 200 extends into the opening of the dust collection hood 110. During the rotation and pressing of the material by the roller 200, the surface of the roller 200 passes sequentially through the scraper 120, nozzle 130, brush 140, and felt 150 as it rotates from the dust collection hood 110 to the outside. The scraper 120 removes residue from the surface of the roller 200, causing large particles to be scraped off and drawn away by the dust collection hood 110.
[0039] The nozzle 130 sprays diluent onto the surface of the roller 200, causing the remaining residue on the surface of the roller 200 to melt or lose its stickiness; the brush 140 brushes away the remaining residue after it has melted or lost its stickiness, causing the remaining residue to detach from the roller 200 and be sucked away by the dust hood 110; the felt 150 cleans away the excess diluent on the surface of the roller 200, so that the excess diluent is also sucked away by the dust hood 110.
[0040] To ensure the scraping effect of the scraper 120, in this embodiment, the scraper 120 is inclined at 15° to 45° relative to the axis of the roller 200. In addition, to prevent the scraper 120 from damaging the surface of the roller 200, the distance between the blade of the scraper 120 and the surface of the roller 200 is 0.1mm.
[0041] Considering that there may be situations where the position of the roller 200 needs to be adjusted in practical applications, in order to adapt to changes in the position of the roller 200, the roller online cleaning mechanism 100 provided in this embodiment also includes a connector 160, and the dust suction hood 110 is connected to the roller 200 through the connector 160.
[0042] During the process of the roller body 200 changing position, the roller body 200 drives the dust collection hood 110 to move synchronously through the connector 160, ensuring that the roller body 200 is always partially inserted into the dust collection hood 110, that is, no additional adjustment is needed to the position of the dust collection hood 110, thereby improving production efficiency.
[0043] In this embodiment, connecting lugs 112 are provided on opposite sides of the outer surface of the dust collection hood 110. One end of the connector 160 is connected to at least one connecting lug 112, and the other end is connected to the roller body 200. It is understood that a bearing can be fitted on the roller body 200, and the connector 160 is connected to the roller body 200 through the bearing to ensure that the roller body 200 can rotate relative to the connector 160.
[0044] To ensure the stability of the dust hood 110 during actual application, thereby ensuring a stable and reliable cleaning effect on the roller body 200, the online cleaning mechanism 100 for the roller body provided in this embodiment also includes a fixing plate 170 and a slide rail 180. The fixing plate 170 is used for connection and fixation with the outside, and the slide rail 180 is set on the fixing plate 170. The dust hood 110 and the slide rail 180 are slidably engaged.
[0045] In practical applications, the fixing plate 170 can be fixed to the main structure of the calendering equipment, and the dust hood 110 slides in conjunction with the slide rail 180, so that the fixing plate 170 provides stable support for the dust hood 110. During the displacement of the dust hood 110 with the roller body 200, the dust hood 110 slides along the slide rail 180 to ensure the smoothness of the sliding process and further ensure the stable and reliable cleaning effect.
[0046] Specifically, there are two slide rails 180, and each of the two connecting ear plates 112 of the dust cover 110 is provided with a fixed slider 113. The two fixed sliders 113 are slidably engaged with the two slide rails 180 respectively, so as to achieve stable support for the dust cover 110 during the sliding process and prevent the dust cover 110 from shaking significantly during the movement of the roller 200.
[0047] To allow for the movement of the dust collection hood 110, in this embodiment, the fixing plate 170 is provided with a clearance groove 171 through which the dust collection hood 110 passes. Furthermore, in the extending direction of the slide rail 180, the size of the clearance groove 171 is larger than the size of the dust collection hood 110. Two slide rails 180 are respectively arranged on opposite sides of the clearance groove 171. During the displacement of the dust collection hood 110 with the roller body 200, the dust collection hood 110 moves within the clearance groove 171.
[0048] Please refer to the following: Figure 3 , Figure 4 and Figure 5 , Figure 3 The image shown is a schematic diagram of a portion of the structure of the online roller cleaning mechanism 100 from one perspective. Figure 4 The image shown is a schematic diagram of part of the roller online cleaning mechanism 100 from another perspective. Figure 5 As shown Figure 4 A cross-sectional view of BB.
[0049] The roller online cleaning mechanism 100 provided in this embodiment also includes a brush drive 190, which is disposed on the dust collection cover 110 and is connected to the brush 140 for driving the brush 140 to rotate in the opposite direction relative to the roller 200.
[0050] Preferably, in this embodiment, the brush drive 190 is a motor, which is mounted on one of the connecting ear plates 112. The roller online cleaning mechanism 100 also includes a transmission pulley 191, which and the brush drive 190 are both disposed on the outer surface of the dust collection cover 110, and the brush drive 190 is connected to the brush 140 through the transmission pulley 191.
[0051] Specifically, the transmission pulley 191 includes two pulleys and a belt sleeved between the two pulleys. One pulley is coaxially mounted on the motor shaft, and the other pulley is rotatably mounted on the outer surface of the dust collection cover 110 and coaxially connected to the brush 140. When the motor is running, it drives the pulley connected to its shaft to rotate, which in turn drives the other pulley to rotate synchronously via the belt, thereby driving the brush 140 to rotate.
[0052] Understandably, the brush 140 contacts the surface of the roller 200. The rotation direction of the brush 140 is opposite to that of the roller 200. For example, if the roller 200 rotates counterclockwise, the brush 140 rotates clockwise, which can achieve a better brushing effect.
[0053] To facilitate the delivery of external diluent to the nozzle 130, in this embodiment, the dust hood 110 is also equipped with a diluent connector 111, which is connected to the nozzle 130. In practical applications, the diluent connector 111 can be connected to a supply device via a pipeline to deliver the diluent stored in the supply device to the nozzle 130. A pumping device can be installed on the pipeline to ensure that the nozzle 130 sprays the diluent at sufficient pressure.
[0054] It should be noted that the diluent can be a liquid that can dissolve the residue or a liquid that can remove the stickiness of the residue. The specific choice can be made according to the type of material in the actual application scenario.
[0055] Considering that some special diluents may be difficult to completely remove from the felt 150 and remain on the surface of the roller 200, in order to avoid the residual diluent from affecting the material, in another embodiment, the roller online cleaning mechanism 100 may also include a drying device. The dust hood 110 and the drying device are arranged in sequence along the rotation direction of the roller 200, and the drying device is used to dry the surface of the roller 200.
[0056] The drying device is connected to the dust hood 110 and can move synchronously with the dust hood 110. Specifically, it can apply the principle of heating drying or the principle of blowing air drying to achieve the drying effect on the surface of the roller body 200.
[0057] In summary, the online cleaning mechanism 100 for rollers provided in this embodiment can perform online cleaning of rollers 200, including calendering rollers of calendering equipment and rolling mill rolls, with high cleaning efficiency and good cleaning effect, thereby improving product quality and production efficiency.
[0058] In addition, this embodiment also provides a calendering equipment, including the aforementioned online roller cleaning mechanism 100. The dust collection hood 110 of the online roller cleaning mechanism is connected to the calendering roller of the calendering equipment through a connector 160 to realize online cleaning of the calendering roller.
[0059] Benefiting from the advantages of the online roller cleaning mechanism 100, the calendering equipment provided in this embodiment has the characteristics of better calendering effect and higher production efficiency.
[0060] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
