Description

Technical Field

[0001] The utility model relates to the technical field of sheet material transmission, in particular to a glue pressing roller heating module. Background Art

[0002] When applying tape to products such as lithium battery electrodes, the tape typically needs to be heated. Existing technology generally uses an electrically heated roller device to heat the tape. The heating core is installed in the laminating roller via stop rings on both sides of the outlet and fixed sides. During the rotation of the laminating roller, the pressure cannot be adjusted. If the pressure is too tight, it can easily damage the tape. If the pressure is too loose, the tape will not be heated sufficiently, affecting product quality. Furthermore, the contact surface between the laminating roller and the tape is prone to adhesion, making the laminating roller unable to function normally for a long time. Utility Model Content

[0020] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the embodiments of the present invention, all other embodiments obtained by those skilled in the art should fall within the scope of protection of the embodiments of the present invention.

[0021] See also Figures 1 to 4 , is a preferred embodiment of the present invention, the glue pressing roller heating module includes a glue pressing roller 1, a heating tube 2 and a pressure regulating unit. The heating tube 2 is installed in the glue pressing roller 1, and the heat generated by the heating tube 2 can be transferred to the glue pressing roller 1, and the glue pressing roller 1 is fitted with the tape (not shown in the figure) to achieve contact heating of the tape. The pressure regulating unit includes a lifting cylinder 3, a pressure sensor 4 and a pressure controller (not shown in the figure). The glue pressing roller 1 is connected to the piston of the lifting cylinder 3, and it can move with the piston of the lifting cylinder 3. The pressure sensor 4 is used to detect the pressure value between the tape and the glue pressing roller 1, and the pressure controller is used to adjust the air pressure of the lifting cylinder 3 according to the signal fed back by the pressure sensor 4, thereby adjusting the pressure value so that the glue pressing roller 1 and the tape are properly fitted and heat is transferred.

[0022] In this embodiment, the heating module also includes a pressure roller base 5 and a link plate 6. The rubber pressing roller 1 is rotatably mounted on the pressure roller base 5, with its axial direction perpendicular to the pressure roller base 5. The pressure sensor 4 is located radially above the pressure roller base 5, and the link plate 6 is connected between the piston of the lifting cylinder 3 and the pressure sensor 4. Specifically, the pressure sensor 4 is mounted on the pressure roller base 5 via a sensor mounting plate 7, which is located between the pressure roller base 5 and the pressure sensor 4. The heating module also includes a fiberglass board 8 and a connecting plate 9. The fiberglass board 8 is located between the pressure roller base 5 and the sensor mounting plate 7, providing insulation to prevent heat generated by the heating tube 2 from being conducted through the board. The connecting plate 9 is fixed to the piston of the lifting cylinder 3, and the link plate 6 is fixed to the connecting plate 9. The ends of the link plate 6 are connected to the pressure sensor 4 and the connecting plate 9, respectively. The rubber pressing roller 1 includes a rotating shaft 101, a bearing 102, a pressure roller 103, and a rubber pressing roller 104. The bearing 102 is sleeved on the rotating shaft 101, the pressure roller 103 is sleeved on the bearing 102, and the rubber pressing roller 104 is sleeved on the pressure roller 103. In this embodiment, a bearing 102 is sleeved on each end of the rotating shaft 101. The heating tube 2 is axially inserted into the rotating shaft 101 and the pressure roller base 5 along the rotating shaft 101, and is bent and extended out of the pressure roller base 5. The heat generated by the heating tube 2 can be transferred to the rubber pressing roller 104 through the rotating shaft 101 and the pressure roller 103 in sequence. The rubber pressing roller 104 is made of an anti-stick material and a surface spraying process to reduce the amount of glue adhering to the rubber pressing roller 1. The rubber pressing roller 1 also includes a baffle 105, which is located outside the pressure roller 103 and is screwed to the pressure roller 103. After working for a period of time, if there is too much glue on the pressing wheel 104, which affects the gluing effect, the screws on the baffle 105 can be removed, the baffle 105 can be removed, and a new pressing wheel 104 can be replaced. Then the baffle 105 can be re-locked on the pressing wheel 103. The pressing wheel 104 can be replaced quickly, and the operation is very convenient.

[0023] To prevent excessive impact when the piston of lift cylinder 3 moves, the heating module also includes a buffer screw 10 and a buffer pad 11. The buffer screw 10 extends vertically through link plate 6, and the buffer pad 11 is located below the buffer screw 10 (i.e., near the end of the rubber-pressing roller 1). The buffer pad 11 is made of rubber and is fixed to a buffer mounting plate 12. When the buffer screw 10 hits the buffer pad 11, it provides a certain degree of cushioning, thereby ensuring smoother movement of the rubber-pressing roller 1.

[0024] The above-mentioned heating module also includes a temperature measuring probe 13 and a temperature controller (not shown in the figure). The temperature measuring probe 13 is used to detect the temperature of the tape. It is fixed to the sensor mounting plate 7 through a sensor mounting plate 14. The temperature controller is used to control the temperature of the heating tube 2 according to the signal fed back by the temperature measuring probe 13 to prevent the heating temperature of the tape from being too high or too low.

[0025] The above-mentioned glue pressing roller heating module can be used as one of the processing links of product production and processing equipment (such as lithium battery electrode gluing equipment). The lifting cylinder 3 is fixed on a mounting plate 15, and the mounting plate 15 and the buffer mounting plate 12 are both installed on the equipment.

[0026] During operation, the lifting cylinder 3 drives the glue pressing roller 1 to contact the tape. The pressure sensor 4 detects the pressure between the glue pressing roller 1 and the tape and feeds it back to the pressure controller. Based on the feedback signal from the pressure sensor 4, the pressure controller issues a command to adjust the air pressure in the lifting cylinder 3, so that the glue pressing roller 1 and the tape are properly contacted and heat is transferred. At the same time, the temperature probe 13 detects the temperature of the tape and feeds it back to the temperature controller. Based on the feedback signal from the temperature probe 13, the temperature controller issues a command to adjust the temperature of the heating tube 2, so that the glue pressing roller 1 heats the tape at the appropriate contact temperature, preventing overheating or insufficient heating.

[0027] The present invention's glue roller heating module incorporates a pressure regulating unit that controls the pressure between the glue roller 1 and the tape by adjusting the air pressure, thereby preventing the tape from being damaged by excessive pressure. The glue roller heating module heats the tape without affecting the adhesive bonding of the tape, resulting in better heat absorption, higher-quality products, and reduced risk of damage during production.

[0028] The above embodiments are only preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be regarded as equivalent replacement methods and are included in the scope of protection of the present invention.
