DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 — Figure 6 As shown, this embodiment provides a conductive sponge production equipment, including a unwinding system 1, an immersion system 2, an in-pool extrusion system 3, an auxiliary extrusion system 4 and an out-pool extrusion system 5, the in-pool extrusion system 3 is installed in the immersion system 2, the unwinding system 1 and the out-pool extrusion system 5 are respectively installed at both ends of the immersion system 2, the in-pool extrusion system 3 has a plurality of extrusion channels 6, the immersion system 2 is filled with commercially available conductive liquid, the conductive liquid is commercially available and will not be described in detail here, the in-pool extrusion system 3 is used to squeeze the sponge sheet in the immersion system 2, so that the sponge sheet absorbs the conductive liquid, the auxiliary extrusion system 4 includes two auxiliary extrusion racks 41, two extrusion devices 43 and two traction wheels 44, the two auxiliary extrusion racks 41 are installed in the immersion system 2, and the extrusion device 43 is installed in the corresponding auxiliary extrusion rack 41 in a liftable manner. On the top, two traction wheels 44 are rotatably installed on the corresponding auxiliary extrusion frame 41, and the surfaces of the two traction wheels 44 protrude from the surface of the auxiliary extrusion frame 41. Each traction wheel 44 is transmission-connected to the corresponding extrusion device 43. Two injection chambers 42 are formed between the two auxiliary extrusion frames 41. The two injection chambers 42 are respectively located on both sides of the auxiliary extrusion frame 41. The two injection chambers 42 extend into the corresponding extrusion channel 6. The injection chamber 42 is connected to an injection pump, which actively injects the conductive liquid into the injection chamber 42, and actively feeds the sponge sheet located at the position of the extrusion channel 6 to ensure that the sponge sheet is soaked. The sponge sheet passes through the surface of the auxiliary extrusion frame 41, and the two traction wheels 44 follow the rotation, so that the extrusion device 43 rises and falls, and repeatedly squeezes the sponge sheet into the pool extrusion system 3 at the position of the extrusion channel 6 to promote the sponge sheet to absorb the conductive liquid.

[0024] Specifically, the unwinding system 1 includes a plurality of unwinding rollers, each of which is rotatably mounted on one side of the soaking system 2. The unwinding rollers are all connected to an unwinding motor to realize the unwinding of the sponge sheet roll.

[0025] Specifically, the soaking system 2 includes a soaking pool 21 and several soaking guide rollers 22. Each soaking guide roller 22 is rotatably installed in the soaking pool 21. The in-pool squeezing system 3 is installed in the soaking pool 21. The unwinding system 1 and the out-pool squeezing system 5 are respectively installed at both ends of the soaking pool 21 to realize the soaking of the sponge sheet.

[0026] Specifically, the in-pool squeezing system 3 includes a plurality of pairs of in-pool squeezing rollers 31 rolling against each other, and adjacent in-pool squeezing rollers 31 form squeezing channels 6, so that the sponge sheet is deformed in the soaking pool 21 to facilitate absorption of the conductive liquid.

[0027] Specifically, the out-pool extrusion system 5 includes a guide groove 51 and several pairs of out-pool extrusion rollers 52 that roll against each other. An extrusion channel 6 is formed between adjacent out-pool extrusion rollers 52. Each out-pool extrusion roller 52 is rotatably installed on the guide groove 51. The guide groove 51 is installed on the side of the immersion system 2. The soaked sponge sheet passes between the adjacent out-pool extrusion rollers 52 to squeeze out excess conductive liquid. The side of the guide groove 51 close to the immersion system 2 is lower than the side away from the immersion system 2, which facilitates the backflow of the conductive liquid.

[0028] Specifically, the two auxiliary extrusion frames 41 form a spindle shape, which is convenient for guiding the sponge sheet. One of the two traction wheels 44 above is at the upper end of the upper auxiliary extrusion frame 41 and protrudes from the upper surface of the auxiliary extrusion frame 41, and the other is at the lower end of the lower auxiliary extrusion frame 41 and protrudes from the lower surface of the auxiliary extrusion frame 41. The two auxiliary extrusion frames 41 form a spindle shape so that the sponge sheet can be fully squeezed by the corresponding traction wheel 44, ensuring the rotation of the traction wheel 44.

[0029] Specifically, the injection cavity 42 is connected to the auxiliary extrusion frame 41 on both sides and is provided with a liquid injection grid 421. The sponge sheet forms a deformation zone under the extrusion of the extrusion roller 31 in the adjacent pool. The injection cavity 42 actively injects material into the deformation area of ​​the sponge sheet through the liquid injection grid 421, so as to facilitate the sponge sheet to absorb the conductive liquid.

[0030] Specifically, the extrusion device 43 includes an extrusion supporting sheet 431, both ends of which extend to the extrusion channel 6. The position of the extrusion supporting sheet 431 extending to the extrusion channel 6 is provided with an extrusion plate 432 extending from the corresponding auxiliary extrusion frame 41. The extrusion plate 432 assists in extruding the sponge sheet to facilitate the soaking of the sponge sheet. Guide slopes are provided on both sides of the extrusion plate 432 to reduce the movement resistance of the sponge sheet. The extrusion supporting sheet 431 is provided with a number of sliding columns 4311 that slide along the auxiliary extrusion frame 41 to achieve stable lifting and lowering of the extrusion supporting sheet 431.

[0031] Specifically, the traction wheel 44 is provided with a number of traction friction plates 441 evenly arranged along the circumference. A connecting rod is installed at the eccentric position of the traction wheel 44. The two ends of the connecting rod are rotatably installed on the traction wheel 44 and the extrusion bearing plate 431 of the extrusion device 43 to realize the lifting and lowering of the extrusion device 43. The traction friction plate 441 not only rubs against the sponge plate to realize transmission, but the flow of the sponge plate also causes the conductive liquid adjacent to the sponge plate to flow, and the flowing conductive liquid also has a driving effect on the traction friction plate 441.

[0032] The conductive sponge production process, using conductive sponge production equipment, includes the following steps: S1: Unwinding system 1 unwinding; S2: The sponge sheet enters the immersion system 2, which is filled with conductive liquid. The sponge sheet passes through the squeezing system 3 in the pool and then passes through the squeezing system 3 in the pool. S3: The sponge sheet passes along the surface of the auxiliary extrusion frame 41, and the sponge sheet drives the two traction wheels 44 to rotate; S4: The traction wheel 44 drives the corresponding extrusion device 43 to rise and fall along the auxiliary extrusion frame 41, so that the extrusion device 43 repeatedly squeezes the sponge sheet toward the extrusion system 3 in the pool to ensure that the sponge sheet is soaked and the conductivity of the conductive sponge is ensured; S5 : the injection cavity 42 squeezes out the conductive liquid in the extrusion channel 6 , and the conductive liquid flows back to the immersion system 2 .
