[0001] The utility model belongs to the technical field of processing of needle-punched steel strips for pouch batteries, and particularly relates to a perforating die for high-porosity round-hole needle-punched steel strips for pouch batteries. Background Technique

[0002] The needle-punched steel strip for pouch batteries is a key material for manufacturing the electrode plates of pouch batteries. This kind of steel strip usually undergoes special processing techniques to form a porous structure to facilitate the penetration of the electrolyte and the chemical reactions inside the battery. The design of the needle-punched steel strip aims to improve the performance of pouch batteries, especially in terms of the electrolyte penetration speed and charge-discharge rate. However, it still has the following drawbacks in actual use:

[0003] During the processing of the needle-punched steel strip, in order to ensure the stability of the steel strip processing, after guiding the steel strip to a suitable position, the steel strip is then needle-punched to form round holes. During the process of transporting the steel strip, wrinkles are likely to occur on the steel strip during the guiding process, affecting the uniformity of the working perforation of the steel strip.

[0004] During the processing of the needle-punched steel strip, a large amount of debris is generated when the steel strip is punctured. The debris directly falls into the working environment, polluting the on-site working environment. And during the operation, the debris enters the equipment, affecting the safe use of the equipment. Content of the Utility Model

[0005] The purpose of the utility model is to provide a perforating die for high-porosity round-hole needle-punched steel strips for pouch batteries. By setting a support plate, a long screw, a mounting plate, a pressing plate and a waste box, the problems that wrinkles are likely to occur on the steel strip during the transportation process and other processes during the processing of the needle-punched steel strip, affecting the uniformity of the working perforation of the steel strip, and the debris will splash everywhere during the perforation process, affecting the safe use of the equipment are solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a perforating die for high-porosity round-hole needle-punched steel strips for pouch batteries, which includes a support plate, a long screw, a mounting plate, a pressing plate and a waste box. Installation blocks are fixed in the middle of one side of the two support plates. An installation plate is jointly arranged on the side of the two support plates away from the installation blocks. Needle pins are evenly fixed at the bottom of the installation plate. A pressing plate is arranged at the bottom of the installation plate. A waste box is arranged below the pressing plate. A long screw is threadedly connected through each installation block. During work, the pressure roller is supported on it through the support plate. The rotating frame and the limiting block are connected through the long screw. The needle pins are fixed at the bottom of the installation plate through the installation plate. The pressing plate is used to support the steel strip that needs to be needle-punched and perforated. The waste box is used to support the debris generated when the steel strip is perforated.

[0008] Furthermore, two upper and lower corresponding pressure rollers are connected and rotated together between the two support plates. A driving motor is fixed to the upper part of one side of the support plate away from the pressure roller. The output end of the driving motor is inserted into the support plate and fixed to one end of the pressure roller located above. The support plate squeezes the steel belt through the pressure roller, and the pressure roller is driven to rotate by the driving motor.

[0009] Furthermore, a screw hole is provided in the installation block along the center line connecting the two end faces, the long screw rod is threadedly connected in the screw hole, and the installation block is threadedly connected to the long screw rod through the screw hole.

[0010] Furthermore, a limit block is fixed at one end of the two long screws that are close to each other, and a rotating frame is fixed at one end of the two long screws that are away from each other. The limit block is driven to move by rotating the rotating frame, so that the limit block can limit the conveying position of the steel belt.

[0011] Furthermore, connecting plates are symmetrically fixed at both ends of the mounting plate, an electric push rod is arranged under each of the connecting plates, the telescopic ends of the four electric push rods are respectively fixed to the four connecting plates, the mounting plate is connected to the electric push rods through the connecting plates, and the mounting plate is driven to rise and fall by the electric push rods.

[0012] Furthermore, the pressure plate is provided with vertically and evenly extending holes, the pins correspond to the positions of the holes one by one, the pins are inserted into the holes, and the diameter of the holes is larger than the diameter of the pins, and support legs are fixed at the four corners of the bottom of the pressure plate, and the pressure plate is supported on the ground by the support legs.

[0013] Furthermore, a handle is fixed at one end of the waste box, and a feeding trough is commonly provided on one side between the two mounting blocks away from the support plate, and the waste box is provided with a pulling function from under the pressure plate through the handle.

[0014] The utility model has the following beneficial effects:

[0015] The utility model solves the problem that wrinkles are easily caused on the steel strip during the conveying process during the needle-punched steel strip processing, thereby affecting the uniformity of the steel strip's working perforations, by arranging a supporting plate, a long screw, a mounting plate and a pressing plate. The steel strip is guided between the two pressing rollers through the feed trough. After the width of the steel strip is determined, the rotating frame is rotated to drive the long screw to rotate until the limit block moves to a suitable position. The long screw limits the conveying position of the steel strip through the limit block to prevent the steel strip from lateral deviation. The driving motor drives the pressing roller to rotate. When the steel strip is guided between the two pressing rollers through the feed trough, the pressing roller rotates to flatten the steel strip and pull it to the top of the pressing plate, thereby better ensuring the uniformity of the steel strip's puncture.

[0016] The utility model solves the problem that debris will splash everywhere during the perforation process of needle-punched steel strips, affecting the safety of equipment operation, by setting a support plate, a mounting plate, a pressing plate and a waste box. When the electric push rod is started, the electric push rod drives the connecting piece to descend, so that the mounting plate descends to press on the top of the pressing plate. After the needle penetrates the steel strip on the top of the pressing plate and inserts into the jack, the steel strip is perforated. The debris generated during the perforation process falls into the waste box in the jack, so that the debris will not splash everywhere during the perforation process of the needle-punched steel strip, and is better collected.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention. Specific Embodiment 1

[0027] Please refer to Figure 1-6 , the present invention is a high-porosity round-hole needle-punched steel strip perforating die for a bag-type battery, including a support plate 1, a long screw 2, a mounting plate 3, a pressing plate 4 and a waste box 5. At the middle of one side of the two support plates 1, mounting blocks 101 are fixedly arranged. The support plates 1 connect the long screw 2 thereto through the mounting blocks 101, and the support plates 1 provide the connection and support of the pressure roller 103. On the side of the two support plates 1 away from the mounting blocks 101, a mounting plate 3 is jointly arranged. The mounting plate 3 fixes the insertion needles 301 at its bottom. The insertion needles 301 are evenly fixed at the bottom of the mounting plate 3. By inserting the insertion needles 301 into the pressing plate 4, the steel strip of the bag-type battery passing through the pressing plate 4 is perforated. A pressing plate 4 is arranged at the bottom of the mounting plate 3. The pressing plate 4 provides the function of conveying the steel strip. A waste box 5 is arranged below the pressing plate 4. The waste box 5 receives the debris generated on the pressing plate 4. A long screw 2 is threadedly connected through each mounting block 101. When the long screw 2 rotates, the restriction on the steel strip is changed.

[0028] Specifically, two upper and lower corresponding pressure rollers 103 are rotatably connected between the two support plates 1. On the upper part of one side of the support plate 1 away from the pressure roller 103, a driving motor 104 is fixedly arranged. The output end of the driving motor 104 is inserted through the support plate 1 and fixed to one end of the upper pressure roller 103. The driving motor 104 drives the pressure roller 103 to rotate. When the steel strip is guided between the two pressure rollers 103 through the feeding groove 6, the steel strip is flattened by the rotation of the pressure roller 103 and pulled to the top of the pressing plate 4.

[0029] Further, a threaded hole 102 is formed through the center connection line of the two end faces in the mounting block 101, and the long screw 2 is threadedly connected through the threaded hole 102. The mounting block 101 is threadedly connected to the long screw 2 through the threaded hole 102.

[0030] Further, limit blocks 202 are fixed at one ends of the two long screws 2 close to each other, and rotary frames 201 are fixed at the ends of the two long screws 2 away from each other. The long screws 2 limit the position of the steel strip conveying through the limit blocks 202 to prevent the steel strip from deviating sideways. By rotating the rotary frames 201, the long screws 2 are driven to rotate. When the long screws 2 rotate, the limit blocks 202 are driven to move.

[0031] The operation process of this embodiment is as follows: During operation, the steel strip is guided between the two pressure rollers 103 through the feeding chute 6. After determining the width of the steel strip, the rotating frame 201 is rotated to drive the long screw 2 to rotate. Until the limit block 202 moves to a suitable position, the long screw 2 restricts the position of the steel strip conveyance through the limit block 202 to prevent the steel strip from deviating sideways. The driving motor 104 drives the pressure rollers 103 to rotate. When the steel strip is guided between the two pressure rollers 103 through the feeding chute 6, the steel strip is flattened by the rotation of the pressure rollers 103 and pulled to the top of the pressing plate 4. Specific Embodiment Two

[0032] Please refer to Figure 1 、 2 Figures 4, 5, and 6. On the basis of Specific Embodiment One, connecting pieces 302 are symmetrically and fixedly arranged at both ends of the mounting plate 3. Electric push rods 303 are arranged below each connecting piece 302. The telescopic ends of the four electric push rods 303 are respectively fixed to the four connecting pieces 302. The mounting plate 3 is fixed to the telescopic ends of the electric push rods 303 through the connecting pieces 302. The connecting pieces 302 are driven to rise and fall by the electric push rods 303, driving the mounting plate 3 to rise and fall.

[0033] Specifically, insertion holes 401 are vertically and uniformly formed through the pressing plate 4. The positions of the insertion pins 301 correspond to those of the insertion holes 401 one by one. The insertion pins 301 are inserted into the insertion holes 401, and the diameter of the insertion holes 401 is larger than that of the insertion pins 301. Support legs 402 are fixed at the four corners of the bottom of the pressing plate 4. The pressing plate 4 is movably connected to the insertion pins 301 through the insertion holes 401. After the insertion pins 301 pass through the steel strip at the top of the pressing plate 4 and are inserted into the insertion holes 401, the steel strip is perforated.

[0034] Furthermore, a handle 501 is fixed at one end of the waste box 5. A feeding chute 6 is commonly arranged on the side of the two mounting blocks 101 away from the support plate 1. The bottom of the feeding chute 6 is supported on an external support structure. By pulling the handle 501, the waste box 5 is pulled out from the bottom of the pressing plate 4, and the steel strip is guided between the two pressure rollers 103 through the feeding chute 6.

[0035] The operation process of this embodiment is as follows: During operation, when the steel strip is rotated and guided by the pressure roller 103 to the top of the pressure plate 4, after the steel strip covers the top of the pressure plate 4, the driving motor 104 is turned off, and the electric push rod 303 is started. The electric push rod 303 drives the connecting piece 302 to descend, so that the mounting plate 3 descends to press on the top of the pressure plate 4. After the pin 301 passes through the steel strip on the top of the pressure plate 4 and is inserted into the jack 401, the steel strip is perforated. The debris generated during the perforation process falls into the waste box 5 in the jack 401. After completion, the electric push rod 303 is started to drive the mounting plate 3 to rise. At this time, the driving motor 104 and the device for externally conveying the steel strip are started, and the steel strip is conveyed to the device for the next processing step. When the steel strip perforation waste received in the material conveying groove 6 at the bottom of the pressure plate 4 needs to be cleaned, the handle 501 is pulled to draw out the waste box 5 from the bottom of the pressure plate 4. After pouring out the waste, the handle 501 is pushed to reset the waste box 5.
