DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0026] Please refer to Figures 1-4As shown, an electrode foil pre-treatment preheating device includes a height-adjusting clamp roller 1 and a preheating roller 2, a liquid collecting hopper 3 is arranged directly below the preheating roller 2, a spraying pipe 6 is fixedly connected to the inside of the liquid collecting hopper 3 along the axial direction of the preheating roller 2, a spray head 5 is fixedly connected to the side of the spraying pipe 6 adjacent to the preheating roller 2, the spraying pipe 6 is communicated with a pre-treatment tank 4 through a liquid conveying pipeline, and a liquid pump is arranged on the liquid conveying pipeline; the height-adjusting clamp roller 1 is arranged on the feeding side of the preheating roller 2, and is used for adjusting the feeding height to control the contact area of the material with the roller surface of the preheating roller 2. Specifically, the liquid collecting hopper 3 is communicated with the pre-treatment tank 4 through a liquid discharging pipe 7.

[0027] When the electrode foil is preheated, the liquid in the pre-treatment tank 4 is pumped to the spraying pipe 6 by the liquid pump, and then the liquid is sprayed onto the preheating roller 2 by the spray head 5 to heat the preheating roller 2. When the electrode foil passes through the preheating roller 2, heat is transferred to the electrode foil to preheat the electrode foil, and the sprayed liquid is collected by the liquid collecting hopper 3 and discharged back to the pre-treatment tank 4.

[0028] When it is necessary to adjust the preheating time, the height of the electrode foil on the feeding side of the preheating roller 2 is adjusted by the height-adjusting clamp roller 1, so as to adjust the contact area of the electrode foil with the roller surface of the preheating roller 2, thereby achieving the control of the preheating time.

[0029] In order to avoid the stagnation of the liquid in the liquid collecting hopper 3, the bottom end of the liquid collecting hopper 3 is arc-shaped.

[0030] Specifically, the liquid collecting hopper 3 is driven to rotate by a servo motor. Preferably, the linear speed of the roller surface of the liquid collecting hopper 3 is the same as the conveying speed of the electrode foil, so as to avoid the sliding of the electrode foil relative to the roller surface of the preheating roller 2, thereby preventing the damage of the foil surface.

[0031] In some embodiments, the height-adjusting clamp roller 1 includes a sliding block 11 and roller cylinders 14, both ends of the roller cylinders 14 are rotationally connected with the sliding block 11, the sliding block 11 is slidingly connected with a mounting frame 12 through a slide rod 9 and is driven to slide by a screw rod 8. Specifically, the screw rod 8 is threadedly connected with the mounting frame 12, and one end of the screw rod 8 is rotationally connected with the sliding block 11.

[0032] When the feeding height of the electrode foil is adjusted, the screw rod 8 is rotated to drive the sliding block 11 to slide along the slide rod 9, so as to adjust the height of the two roller cylinders 14, and the adjustment of the feeding height of the electrode foil is realized under the limiting of the roller cylinders 14.

[0033] Specifically, the sliding block 11 is fixedly connected with the mounting frame 12 through a bolt, and a strip hole 10 through which the bolt passes is formed on the mounting frame 12 along the sliding direction of the sliding block 11. After the height adjustment is completed, the sliding block 11 is fixed with the mounting frame 12 through the bolt, so as to avoid the sliding of the sliding block 11 relative to the mounting frame 12.

[0034] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
