[0036] In order to facilitate the belt running of the diaphragm material belt, in the embodiment, reference Figures 1 to 3The walking channel 51 is arranged through the thickness direction of the splicing platform 201.
[0037] It can be understood that, in this way, the walking channel 51 is perpendicular to the splicing plane, the new and old diaphragm material belts are spliced on the splicing plane, and the spliced diaphragm material belt is conveyed to the laminating station of the cutting laminator through the walking channel 51, so that the splicing operation of the new and old diaphragm material belts does not affect the walking of the diaphragm, and the subsequent roller or diaphragm material belt is prevented from being scratched during the cutting of the diaphragm, thereby ensuring the safety of the equipment.
[0038] In order to press the new and old diaphragm material belts during splicing, in the embodiment, referring to Figures 1 to 4 , the splicing platform 201 is provided with a driving cylinder on the other side of the splicing plane, and the two ends of the first pressing block 31 and the two ends of the second pressing block 41 are connected with a driving cylinder.
[0039] It can be understood that, in this way, the four driving cylinders on the splicing platform 201 are two first driving cylinders 33 connected with the first pressing block 31 and two second driving cylinders 43 connected with the second pressing block 41, the first driving cylinder 33 drives the first pressing block 31 to press the first diaphragm material belt 103, and the second driving cylinder 43 drives the second pressing block 41 to press the second diaphragm material belt 104, so that the first diaphragm material belt 103 and the second diaphragm material belt 104 are not affected by the unwinding shaft in the splicing area, and the quality of splicing is ensured.
[0040] In order to protect the diaphragm material belt, in the embodiment, referring to Figure 1 , the first pressing block 31 is provided with a first pad 34 on the side of the first splicing channel 32, and the second pressing block 41 is provided with a second pad 44 on the side of the second splicing channel 42.
[0041] It can be understood that, in this way, the first pressing block 31 presses the first diaphragm material belt 103 on the splicing plane through the first pad 34, and the second pressing block 41 presses the second diaphragm material belt 104 on the splicing plane through the second pad 44, the first pad 34 and the second pad 44 are both soft rubber pads, which can better press the diaphragm material belt, and at the same time, the first pressing block 31 and the second pressing block 41 are prevented from scratching the diaphragm material belt.
[0042] In order to accurately position the diaphragm material belt, in the embodiment, referring to Figure 1 , Figure 2 and Figure 4 , a plurality of suction holes 13 distributed in a matrix are arranged on the first suction area 11 and the second suction area 12, and the suction holes 13 are connected with an air source through an air path and a joint 9.
[0043] It can be understood that, thus arranged, the air circuit is arranged inside the receiving platform 201, and each row of suction holes 13 is connected to the air source through an air circuit and a joint 9. The air source generates negative pressure at the suction holes 13 in the form of air suction, thereby adsorbing the diaphragm material belt on the receiving platform. After the diaphragm material belt is adsorbed and positioned, the cutting knife is used to cut the diaphragm material belt, thereby ensuring that the cut diaphragm material belt is flat.
[0044] In order to guide the diaphragm material belt to move, in the embodiment, referring to Figures 1 to 4 , the receiving platform 201 is provided with a mounting hole 52, and a first passing roller 53 and a second passing roller 54 are arranged in parallel in the mounting hole 52.

The first passing roller 53 and the second passing roller 54 can protect the diaphragm material belt from being stably conveyed into the belt moving channel 51.
[0046] In order to stably guide the diaphragm material belt to move, in the embodiment, referring to the figure, the roller surfaces of the first passing roller 53 and the second passing roller are higher than the receiving surface.
[0047] It can be understood that, thus arranged, the roller surfaces of the first passing roller 53 and the second passing roller are higher than the receiving surface. When there is no connection, the first passing roller 53 can lift the first diaphragm material belt 103 away from the receiving surface, and the second passing roller 54 can lift the second diaphragm material belt 104 away from the receiving surface. The first pressing block 31 and the second pressing block 41 move away from the receiving surface under the drive of the driving cylinder, so that the first diaphragm material belt 103 is not in contact with the receiving surface and the first pressing block 31, and the second diaphragm material belt 104 is not in contact with the receiving surface and the second pressing block 41. This reduces the interference of the diaphragm material belt when moving, thereby stably guiding the diaphragm material belt to move.

During the connection operation, the belt pressing cylinder 83 drives the third pressing block 82 to move to the third passing roller 81, so as to clamp the diaphragm material belt between the third pressing block 82 and the third passing roller 81.
[0049] It can be understood that, thus arranged, before the new and old diaphragm material belts are connected, the belt pressing cylinder 83 drives the third pressing block 82 to press the old diaphragm material belt on the third passing roller 81, thereby ensuring that the old diaphragm material belt in the connection area is not affected by the tension.
[0050] In order to better guide the diaphragm material belt, in the embodiment, referring to Figure 3 , the fourth over roller 61 is arranged between the belt receiving platform 201 and the first diaphragm unwinding shaft 101, and the fifth over roller 62 is arranged between the belt receiving platform 201 and the second diaphragm unwinding shaft 102, and the fourth over roller 61 and the fifth over roller 62 are located on the same vertical line.
[0051] It can be understood that, in this way, the fourth over roller 61, the fifth over roller 62, the first over roller 53 and the second over roller 54 are located on the same vertical line, thereby ensuring that the fourth over roller 61 and the first over roller 53 stably guide the first diaphragm material belt 103 to run, and the fifth over roller 62 and the second over roller 54 stably guide the first diaphragm material belt 103 to run, so that the first diaphragm material belt 103 does not contact the belt receiving plane and the first pressing block 31, and the second diaphragm material belt 104 does not contact the belt receiving plane and the second pressing block 41, further ensuring that the diaphragm material belt is not interfered when running, thereby stably guiding the diaphragm material belt to run.
[0052] In order to reduce dust accumulation, in the embodiment, referring to Figure 2 , the belt receiving platform 201 is provided with a dust removal pipe 23 on one side of the first cutter groove 21 and the second cutter groove 22, and the dust removal pipe 23 is fixed to the side of the belt receiving platform 201 away from the belt receiving plane.
