The motor power is transmitted to the thermal laminating roller through a shaft coupling as a transmission component. Alternatively, the first thermal laminating roller driving member 131 or the second thermal laminating roller driving member 132 can be a hydraulic driving device.

[0058] The cleaning mechanism 2 comprises at least one scraper assembly 3 and a driving assembly 4.

[0059] The scraper assembly 3 comprises a scraper 31. The scraper 31 is arranged to be in contact with the surface of the thermal laminating roller and to move relative to the surface of the thermal laminating roller to clean foreign matters on the surface of the thermal laminating roller.

[0060] During the thermal lamination process of the thermal laminating roller, the scraper 31 is in contact with the surface of the thermal laminating roller and moves relative to the surface of the thermal laminating roller to clean foreign matters on the surface of the thermal laminating roller. Therefore, the quality problem of the core package formed by the thermal laminating pole assembly stack due to the adhesion of foreign matters on the surface of the thermal laminating roller can be effectively improved. It can be understood that since the scraper assembly 3 is a moving cleaning, even if there is local wear or damage of the scraper 31, the scraper assembly 3 as a whole can clean the thermal laminating roller comprehensively during the moving cleaning of the scraper 31.

[0061] In some embodiments, the cleaning mechanism 2 comprises the scraper assembly 3 and the driving assembly 4. The driving assembly 4 is connected to the scraper assembly 3 and is used to drive the scraper assembly 3 to move in a unidirectional or bidirectional manner relative to the thermal laminating roller along the axial direction of the thermal laminating roller on the surface of the thermal laminating roller. Wherein, the axial direction of the thermal laminating roller is as shown by the arrow in the figure. Figure 3The X-direction shown, the thermal compounding roller includes the top end face and the bottom end face opposite along the axial direction X of the compounding roller, the single-line movement of the scraper assembly 3 along the axial direction X of the thermal compounding roller is shown as the scraper assembly moving from the side close to the top end face to the side close to the bottom end face along the axial direction X of the thermal compounding roller, or the scraper assembly moving from the side close to the bottom end face to the side close to the top end face along the axial direction X of the thermal compounding roller. It should be noted that the thermal compounding roller rotates spirally along the axial direction, and the scraper assembly 3 moves linearly relative to the thermal compounding roller along the axial direction of the thermal compounding roller.

[0062] The bidirectional movement of the scraper assembly 3 along the axial direction X of the thermal compounding roller is shown as the scraper assembly moving from the side close to the top end face to the side close to the bottom end face along the axial direction X of the thermal compounding roller, and then moving from the side close to the bottom end face to the side close to the top end face along the axial direction X of the thermal compounding roller, so that the entire outer surface of the thermal compounding roller along the axial direction can be effectively cleaned. When the scraper 31 moves to the side close to the bottom end face of the thermal compounding roller, the direction of the driving force of the driving assembly 4 is changed, so that the driving assembly 4 drives the scraper 31 to move from the side close to the bottom end face to the side close to the top end face.

[0063] In some embodiments, the driving assembly 4 includes a lead screw assembly, the lead screw assembly includes at least one lead screw 41 and a lead screw driving member 42, the scraper assembly 3 is fixed to the lead screw 41, and the lead screw driving member 42 is configured to drive the lead screw 41 to move along the axial direction X of the thermal compounding roller.

[0065] The lead screw driving member 42 can be a motor, the power of the motor is transmitted to the lead screw through a transmission member such as a shaft coupling, the surface of the lead screw 41 is provided with a threaded structure, the scraper assembly 3 is fixed to the lead screw 41, the lead screw driving member 42 drives the lead screw 41 to rotate and in turn drives the scraper assembly 3 to move along the axial direction of the lead screw 41, wherein the axial direction of the lead screw 41 is arranged in parallel with the axial direction of the thermal compounding roller.

[0066] The lead screw driving member 42 is installed on the base, the base is fixed to the rack 11 of the thermal compounding mechanism 1, and the base includes opposite first and second fixed parts 211 and 212. The first fixed part 211 is fixed to the first side plate 111 of the rack 11, and the second fixed part 212 is fixed to the second side plate 112 of the rack 11.

[0067] Continuing to refer to Figure 1As shown, the thermal laminating roller device 10 comprises two cleaning mechanisms 2, which are a first cleaning mechanism 201 and a second cleaning mechanism 202 respectively, and the first cleaning mechanism 201 and the second cleaning mechanism 202 are arranged in a spaced manner. The first cleaning mechanism 201 is arranged corresponding to the first thermal laminating roller 121 and is used for cleaning the surface of the first thermal laminating roller 121. The second cleaning mechanism 202 is arranged corresponding to the second thermal laminating roller 122 and is used for cleaning the surface of the second thermal laminating roller 122, so that the first thermal laminating roller 121 and the second thermal laminating roller 122 are both effectively cleaned.

[0068] Reference Figures 1 to 4 In an embodiment provided in the present application, the cleaning mechanism 2 comprises two scraper assemblies 3, and each of the two scraper assemblies 3 comprises a scraper 31. The two scrapers 31 are arranged in a staggered manner, and the two scrapers 31 are configured to clean the same thermal laminating roller. In a specific implementation, the first thermal laminating roller 121 is correspondingly provided with two scraper assemblies 3, and the second thermal laminating roller 122 is also correspondingly provided with two scraper assemblies 3.

[0069] The two scraper assemblies 3 for cleaning the same thermal laminating roller comprise a first scraper assembly 301 and a second scraper assembly 302. The first scraper assembly 301 and the second scraper assembly 302 are fixed on the same driving assembly 4, and the driving assembly 4 is configured to synchronously drive the first scraper assembly 301 and the second scraper assembly 302 to move and make the moving direction of the first scraper assembly 301 opposite to the moving direction of the second scraper assembly 302. For example, the driving assembly 4 drives the first scraper assembly 301 to move right on the surface of the thermal laminating roller relative to the thermal laminating roller along the axial direction of the thermal laminating roller. Correspondingly, the driving assembly 4 drives the second scraper assembly 302 to move left on the surface of the thermal laminating roller relative to the thermal laminating roller along the axial direction of the thermal laminating roller. By arranging the two scraper assemblies 3 to clean the surface of the same thermal laminating roller, the cleaning efficiency of the cleaning mechanism can be improved and the thermal laminating roller can be effectively cleaned. The two scraper assemblies 3 are arranged in a staggered manner on the surface of the thermal laminating roller, so that the scraper assemblies 3 will not miss cleaning the thermal laminating roller in the process of rotating the thermal laminating roller.

[0070] Continuing to refer to Figures 1 to 4 The driving assembly 4 comprises two lead screws 41, which comprise a first lead screw 411 and a second lead screw 412. The screw threads of the first lead screw 411 and the second lead screw 412 are opposite, and the first lead screw 411 and the second lead screw 412 are arranged in a spaced manner. The first scraper assembly 301 is fixed on the first lead screw 411, and the second scraper assembly 302 is fixed on the second lead screw 412. The first lead screw 411 and the second lead screw 412 are configured to be driven by the same lead screw driving member 42, and the lead screw driving member 42 is arranged to drive the first lead screw 411 and the second lead screw 412 to move in opposite directions.

[0071] Two screw rod fixing holes are arranged on the first fixing part 211 and the second fixing part 212 of the base of the cleaning mechanism 2, two ends of the first screw rod 411 are respectively pivotally connected to one of the screw rod fixing holes of the first fixing part 211 and one of the screw rod fixing holes of the second fixing part 212, and two ends of the second screw rod 412 are respectively pivotally connected to the other screw rod fixing hole of the first fixing part 211 and the other screw rod fixing hole of the second fixing part 212.

[0072] The screw rod driving part 42 is fixedly installed on the first fixing part 211 or the second fixing part 212. The screw rod driving part 42 is drivingly connected to one end of the first screw rod 411 and one end of the second screw rod 412 through a transmission assembly 43. The transmission assembly 43 includes a synchronous belt 431 and two synchronous wheels 432, one of which is fixed to one end of the first screw rod 411, and the other is fixed to one end of the second screw rod 412. The synchronous belt 431 is wound around the two synchronous wheels 432. The screw rod driving part 42 drives the two synchronous wheels 432 to rotate, thereby driving the first screw rod 411 and the second screw rod 412 to rotate spirally. The synchronous belt 431 wound around the two synchronous wheels 432 makes the two synchronous wheels 432 have the same operating frequency. When the screw rod driving part 42 drives the two synchronous wheels 432 to rotate, the two synchronous wheels 432 synchronously drive the first screw rod 411 and the second screw rod 412 to rotate. Since the screw threads of the first screw rod 411 and the second screw rod 412 are opposite in direction, the first screw rod 411 drives the first scraper assembly 301 to move leftward along the axial direction of the composite roller, and the second screw rod 412 drives the second scraper assembly 302 to move rightward along the axial direction of the composite roller.

[0073] The base of the cleaning mechanism 2 further includes a sliding rail 23 connected between the first fixing part 211 and the second fixing part 212 of the base.

The scraper fixing seat 32 further includes a screw rod through hole 322, and the scraper fixing seat 32 is connected to the screw rod through the screw rod through hole 322.

When the lifting driving member 331 moves downward, the lifting linkage member 332 is driven to move, and the lifting linkage member 332 drives the scraper 31 to upwardly pop up and leave the surface of the thermal compound roller.

[0076] With reference to the foregoing Figure 5 and Figure 6 , the lifting linkage member 332 comprises a first connecting section 333 and a second connecting section 334 which are connected in a bent manner, one end of the first connecting section 333 is rotatably connected to the lifting driving member 331, the other end of the first connecting section 333 is connected to one end of the second connecting section 334, the other end of the second connecting section 334 is connected to the scraper 31 in a bent manner.
