Description

Technical Field

[0001] The utility model belongs to the technical field of graphite sheet calendering, in particular to a calendering machine used for graphite sheet processing. Background Art

[0002] In the graphite sheet processing process, the graphite material is usually pressed and stretched into a film of a certain thickness through a calender, and then divided into graphite flakes of specific shapes. The graphite calender mainly consists of rollers, a frame, a transmission device and a control system.

[0003] During operation, a calender uses two or more sets of calendering rollers to press graphite material into sheets of a certain thickness. The complex environment in which graphite sheets are processed creates a large amount of dust. Failure to promptly clean the raw material adhering to the calendering rollers can cause defects such as scratches during the calendering process. Therefore, most existing calenders incorporate cleaning mechanisms to remove the raw material from the calendering rollers. However, these cleaning mechanisms are prone to damage after a period of use and are difficult to remove.

[0004] In view of this, how to solve the defects in the above technical solutions has become one of the problems to be solved urgently in the field of graphite rolling technology. Utility Model Content

[0064] like Figures 1 to 6 As shown, this embodiment provides a calender for graphite sheet processing, comprising a frame 1, on which is mounted a reel 2 for winding a base film. The calender is driven by a motor 3. The drive end of the motor 3 passes through the frame 1 and is connected to the reel 2 via a bearing assembly. The motor 3 then rotates a cleaning assembly 5 via a belt drive 4. During use, the motor 3 is activated, which drives the reel 2 to rotate. The rotation of the reel 2 then drives the cleaning assembly 5 to rotate.

[0065] The utility model has a simple overall structure and is easy to disassemble. In actual application, when the cleaning roller is damaged, it is only necessary to use a disassembly tool to knock the fastening shaft of the connecting block out from the shaft hole of the connecting frame to access the position limit between the cleaning roller and the bearing assembly, and then the cleaning assembly can be replaced.

[0066] Furthermore, the cleaning assembly 5 includes a cleaning roller 051, and the cleaning roller 051 is connected to a bearing assembly 055 via a mounting member 053, and the bearing assembly 055 is fixedly mounted on the frame 1 via fastening screws.

[0067] The mounting member 053 includes a cavity for accommodating the cleaning roller 051 and is fixed by a key connection so that the mounting member 053 and the cleaning roller 051 are integrated.

[0068] Furthermore, a connecting frame 0533 is welded on the end face of the mounting member 053 away from the cleaning roller shaft 051 and is integrated therewith. The connecting frame 0533 is provided with a cavity for accommodating the connecting block 0541 and has two groups of oppositely arranged shaft holes 0532.

[0069] Furthermore, four groups of evenly distributed fastening shafts 0542 are provided on the circumference of the connecting block 0541, and the fastening shafts 0542 extend into the shaft hole 0532 for snap-fit ​​connection.

[0070] Furthermore, a connecting component 054 is provided on the end surface of the bearing assembly 055 near the mounting member 053 , which is integrated therewith, and a hole is provided on the connecting component 054 for accommodating the fastening shaft 0542 provided on the connecting block 0541 .

[0071] In this embodiment, when the cleaning roller is damaged, it is only necessary to use a disassembly tool to knock the fastening shaft of the connecting block out of the shaft hole 0532 of the connecting frame 0533 to access the position limit between the cleaning roller and the bearing assembly 055, and then replace the cleaning assembly.

[0072] Furthermore, at least one set of scrapers 052 is fixedly connected to the cleaning roller 051 by a fastening pin, and the scraper 052 at one end away from the cleaning roller 051 is provided with sharp edges, and the outer wall is wrapped with a cleaning layer with a thickness of 3-5 mm to form a cleaning end, and the cleaning end is made of rubber material.

[0073] In this embodiment, the cleaning roller 051 rotates, thereby driving the scraper 052 provided on the cleaning roller to rotate, and the cleaning end of the scraper is used for cleaning. After a period of use, the cleaning end made of rubber material forms bristles after friction, thereby extending the service life of the cleaning roller, reducing the number of replacements, and improving convenience.

[0074] Furthermore, a calendering active roller 6 and a calendering driven roller 9 are arranged parallel to the longitudinal direction of the frame below the cleaning roller shaft 051. The calendering active roller 6 and the calendering driven roller 9 are connected by a gear transmission 8, and the calendering active roller 6 passes through the frame and is connected to the drive assembly 7 through a bearing assembly. The drive assembly 7 is preferably a rotating motor.

[0075] The driving end of the driving assembly is connected to the connecting shaft of the calendering active roller 6 through a bearing assembly, and a driving gear 081 is installed on the shaft 6, and the driving gear 081 is meshed and connected to the driven gear 086. The connecting shaft 082 is outer-circuited with a sleeve 0833, and the sleeve 083 and the connecting shaft 082 are detachably connected.

[0076] In this embodiment, by starting the driving assembly, the driving assembly drives the calendering active roller and the calendering driven roller to rotate synchronously, so that the graphite material placed on the base film passing through the calendering active roller and the calendering driven roller is calendered into a graphite sheet.

[0077] However, in actual application, there is a possibility of material slippage when two sets of calendering rollers rotate in the same direction. In order to solve the above technical problems, please refer to Figure 1A tensioning roller 11 is supported on a support frame 12 welded on the frame 1, and a winding roller 14 for winding the base film is provided on one side of the tensioning roller 11 and is driven by a rotating motor 13.

[0078] In this embodiment, an unwinding roller shaft for winding the bottom film is added, and a winding roller 14 used in conjunction with the unwinding roller is added. When in use, one end of the bottom film is wound around the winding roller 14, and then

[0079] First, place the base film roll on the unwinding roller shaft 2, and the base film passes between the calendering active roller and the calendering driven roller, then passes through the tensioning roller, and is wound on the winding roller. In actual application, the graphite material is stacked on the base film. Through the support of the base film, the pressure applied by the calendering roller can be more evenly distributed. In conjunction with the use of the unwinding roller, the base film and graphite material can be better guided into the extension area, reducing the probability of material slippage.

[0080] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to be limiting. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that modifications or equivalent substitutions to the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
