[0024] The embodiment of the present application provides a bag making machine sealing knife mechanism, which solves the problem that in the prior art, the steps of heat sealing and cutting are usually performed on two platforms, the structure is not compact enough, and during the heat sealing process, the hot knife group is prone to positional displacement after being fixed, which makes position adjustment inconvenient, thus causing deviations in the heat sealing position, which in turn affects the subsequent cutting work, thereby affecting the bag making and packaging of the battery pole pieces. This separate heat sealing and cutting method takes a long time and reduces the efficiency of bag making and packaging of the battery pole pieces.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The utility model embodiment discloses a bag making machine knife sealing mechanism, according to the attached Figure 1-4 As shown, it comprises a moving arm 1, a supporting arm 2 is fixedly connected to the moving arm 1, and a second electric push rod 3 is provided on the supporting arm 2;

[0027] The output end of the second electric push rod 3 is fixedly connected to a heating base 301, and the bottom of the heating base 301 is movably connected to a knife sealing platform 4;

[0028] A heat sealing knife group 5 is provided at the bottom of the sealing knife station 4;

[0029] A waist-shaped hole 401 is provided on the sealing knife platform 4, and a guide rail platform 302 for clamping the sealing knife platform 4 is provided at the bottom of the heating base 301. The heating base is used to provide installation limit for the sealing knife platform and the heat-sealing knife group. With the guide rail platform set at the bottom and the waist-shaped hole design on the sealing knife platform, the position of the sealing knife platform and the heat-sealing knife group is easy to adjust. At the same time, the sealing knife platform and the heat-sealing knife group are laterally supported by the guide rail platform and are not easy to shift, so there will be no heat-sealing position deviation.

[0030] Furthermore, a fixing frame 101 is fixedly connected to the movable arm 1, and a plurality of guide wheels 102 for guiding the diaphragm are arranged on the fixing frame 101. The fixing frame 101 and the plurality of guide wheels 102 are designed to facilitate the transmission of the diaphragm encapsulating the battery pole piece.

[0031] A first electric push rod 201 is fixedly connected to the support arm 2;

[0032] The output end of the first electric push rod 201 is fixedly connected to a shaft seat 202, and a pressure wheel 203 for compressing the diaphragm is rotatably connected to the shaft seat 202. When the diaphragm encapsulating the battery electrode needs to be heat-sealed and cut, the shaft seat 202 and the pressure wheel 203 are pushed to move by the first electric push rod 201, and the pressure wheel 203 is used to compress and limit the diaphragm, so that the diaphragm is not easily displaced during heat sealing and cutting, the position is accurate, and it is not easy to stretch and deform itself, thereby ensuring the stable operation of the bag making machine.

[0033] Specifically, a third electric push rod 6 is fixedly connected to the support arm 2, and a lifting seat 601 is provided at the output end of the third electric push rod 6. A cutting group 7 is provided on the lifting seat 601. The third electric push rod 6 is convenient for driving the lifting seat 601 and the cutting group 7 to move. The cutting group 7 is used to cut the diaphragm. The diaphragm is directly cut after heat sealing, and the heat sealing and cutting processes are integrated on one platform to improve the processing efficiency of the equipment.

When the second electric push rod 3 drives the heating base 301 to move, the heating base 301 drives the slide 304 to slide along the lateral support platform 303. The lateral support platform 303 and the slide 304 are designed to form lateral support for the heating base 301, thereby ensuring that the force on the heating base 301 is stable.

[0035] Furthermore, a cable 305 is fixedly connected to the heating base 301, and a reinforcing bolt 306 is provided at the connection between the cable 305 and the heating base 301.

[0036] The bag-making machine knife-sealing mechanism uses multiple sets of guide wheels 102 to guide the diaphragm when in use. When the diaphragm paper bag needs to be sealed, the diaphragm is positioned on the bottom platform, and the first electric push rod 201 is used to push the shaft seat 202 and the pressing wheel 203 to move, so that the pressing wheel 203 presses the diaphragm tightly.

[0037] Then, the second electric push rod 3 is used to push the heating base 301 to move, and the heating base 301 drives the sealing knife platform 4 to move, and the sealing knife platform 4 drives the heat sealing knife group 5 to move, and the heat sealing knife group 5 is used to heat press the diaphragm. The heat sealing knife group 5 provides heat through the heating base 301 to heat press and heat seal the diaphragm, so that the upper and lower diaphragms form a storage space for loading battery pole pieces;

[0038] After the heat-sealing knife group 5 heat-presses the diaphragm, the third electric push rod 6 pushes the lifting seat 601 to move, and the lifting seat 601 drives the cutting knife group 7 to move. The cutting knife group 7 can be used to cut the diaphragm bag after heat sealing, thereby completing the sealing knife process of the diaphragm.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
