Description

Technical Field

[0001] The utility model relates to the technical field of battery protection plates, in particular to a battery protection plate paper feeding device. Background Art

[0002] In the production process of storage batteries, after the electrode group and the battery shell are assembled, the battery needs to be filled with a sufficient amount of sulfuric acid electrolyte and then energized to convert the green plates into positive and negative plates with electrochemical activity.

[0003] During the acid filling process, the impact force generated by the sulfuric acid electrolyte entering the battery casing will damage the plates and cause the lead powder on the plates to fall off. In practice, it is found that placing a protective plate above the plates can act as a buffer during the acid filling process and avoid damage to the plates.

[0004] The protective plate is generally in the form of a roll. When in use, the entire protective plate needs to be cut into multiple strip-shaped protective plates that are consistent with the width of the acid filling port. Since the width of the protective plate after cutting is small, it is very easy to be pulled apart during transportation between the transmission rollers, and manual intervention is required to handle it, which results in long downtime and easily leads to waste of protective plates. Summary of the invention

[0005] In order to solve the problem that the cut protective plate is easily broken during the transportation between driving rollers, the utility model provides a battery protective plate paper feeding device, which realizes the automation of protective plate cutting and paper feeding, saves manpower and avoids the protective plate from breaking.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] A battery protection plate paper feeding device, wherein a cutting unit, a traction unit and a paper separation unit are sequentially arranged along the protection plate conveying direction, wherein the cutting unit cuts a whole piece of protection plate into a plurality of parallel strip protection plates, wherein the traction unit provides power for the operation of the protection plate, wherein the paper separation unit is arranged below the traction unit, wherein the paper separation unit comprises a paper separation roller and a track, wherein the paper separation roller is movably arranged in the track, and wherein the plurality of strip protection plates are connected to a use terminal after bypassing the paper separation roller. The use terminal uses the protection plate.

[0008] Furthermore, it also includes a supporting upright plate, which is arranged on one side or both sides of the cutting unit, the traction unit and the paper separation unit. The track is fixedly connected to the supporting upright plate.

[0009] Furthermore, it also includes a paper feeding unit, the paper feeding unit includes a paper feeding roller, the paper feeding roller is rotatably connected to the supporting upright plate, and a protective plate is wound around the paper feeding roller. The paper feeding unit provides raw materials for the operation of the device.

[0010] Furthermore, the cutting unit comprises a fixing seat, a clamping block and a blade, the two ends of the fixing seat are fixedly connected to the supporting upright plate, a plurality of clamping blocks are arranged in parallel on the fixing seat, a blade is arranged between the clamping blocks, and the blade abuts against the surface of the protective plate. The blade is used to cut the protective plate.

[0011] Furthermore, the traction unit comprises two traction rollers rotating in opposite directions, the protective plate is clamped between the two traction rollers, and the traction rollers are driven by a motor. When the motor is turned on, the two traction rollers rotate in opposite directions, driving the protective plate to move downward.

[0012] Furthermore, the traction roller is a rubber roller, which is used to increase the friction between the traction roller and the protective plate.

[0013] Furthermore, a position switch is provided at the end of the track, and the position switch controls the opening and closing of the traction unit according to the position of the paper separation roller, thereby ensuring that the protective plate will not break during the movement.

[0014] Furthermore, the paper separation roller is provided with a plurality of annular grooves at equal intervals, and the number of the annular grooves is not less than the number of strips of the protective plates formed after the protective plates are cut, so as to avoid the protective plates from being entangled with each other.

[0015] Through the above technical solution, the beneficial effects of the utility model are:

[0016] The protective plate of the utility model passes through a cutting unit, a traction unit and a paper separation unit in sequence and then reaches a use terminal. The cutting unit cuts the whole protective plate into a plurality of parallel strip-shaped protective plates. The traction unit pulls the protective plate to control the length of the protective plate in the device. The paper separation unit separates the plurality of parallel strip-shaped protective plates for separate use by the use terminal, thereby realizing automatic cutting and paper feeding of the protective plate and greatly saving labor costs.

[0017] The paper separation unit of the utility model comprises a paper separation roller and a track which is slidably connected to the paper separation roller. When the length of a protective plate between a use terminal and the paper separation roller is reduced, the protective plate drives the paper separation roller to slide in the track. When the paper separation roller approaches a position switch at the top end of the track, a motor is started to drive a traction roller to work and release the protective plate, thereby increasing the length of the protective plate between the use terminal and the paper separation roller and preventing the protective plate from breaking during use and traction.

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0024] like Figure 1 to Figure 4 As shown, this embodiment provides a battery protection plate paper feeding device, including a supporting upright plate, in which a paper feeding unit 1, a cutting unit 2, a traction unit 3 and a paper separation unit 4 are sequentially arranged along the conveying direction of the protection plate 6. The supporting upright plate is arranged on one side or both sides of the cutting unit 2, the traction unit 3 and the paper separation unit 4.

[0025] The paper feeding unit 1 comprises a paper feeding roller 11, which is rotatably connected to the supporting upright plate, and a protective plate 6 is wound around the paper feeding roller 11. The paper feeding unit 1 provides raw materials for the operation of the device, and the raw materials are uncut protective plates 6.

[0026] The traction unit 3 includes two traction rollers 31 rotating in opposite directions, and the protective plate 6 is clamped between the two traction rollers 31. The traction rollers 31 are driven by a motor 32. The traction rollers 31 are rubber rollers used to increase the friction between the traction rollers 31 and the protective plate 6. The traction unit 3 provides power for the operation of the protective plate 6.

[0027] The cutting unit 2 is arranged between the paper feeding unit 1 and the traction unit 3. Figure 2 As shown, the cutting unit 2 includes a fixing seat 21, a clamping block 22 and a blade 23. Both ends of the fixing seat 21 are fixedly connected to the supporting upright plate. A plurality of clamping blocks 22 are arranged in parallel on the fixing seat 21. A blade 23 is arranged between the clamping blocks 22. The blade 23 abuts against the surface of the protective plate 6. As the protective plate 6 moves, the blade 23 cuts the surface of the protective plate 6. The cutting unit 2 cuts the entire protective plate 6 into a plurality of parallel strip-shaped protective plates 6.

[0028] like Figure 3As shown, the paper separation unit 4 is arranged below the traction unit 3, and the paper separation unit 4 includes a paper separation roller 41 and a track 42, wherein the track 42 is fixedly connected to the supporting upright plate, and the paper separation roller 41 is movably arranged in the track 42, and a plurality of strip-shaped protective plates 6 bypass the paper separation roller 41 and are connected to the use terminal 5. With the use of the protective plates 6, the distance between the use terminal 5 and the paper separation roller 41 is shortened, and the protective plates 6 drive the paper separation roller 41 to slide in the track 42.

[0029] In order to ensure that the protective plate 6 between the traction unit 3 and the user terminal 5 is in a tensioned state and to prevent multiple strip-shaped protective plates from being entangled with each other, the paper separation roller 41 is located on one side of the traction unit 3 and the user terminal 5. In this embodiment, the track 42 is perpendicular to the ground, and the top of the track 42 is not higher than the height of the user terminal 5.

[0030] As an implementable embodiment, a position switch 421 is provided at the end of the track 42, and the position switch 421 controls the opening and closing of the traction unit 3 according to the position of the paper separation roller 41. When the paper separation roller 41 moves to the end of the track 42, the position switch 421 is triggered, and the position switch 421 controls the motor 32 to start, driving the traction roller 31 to work, pulling the protective plate 6 to move downward, and the margin of the protective plate 6 between the terminal 5 and the paper separation roller 41 increases, and the paper separation roller 41 returns to the initial position. Ensure that the protective plate 6 will not break during the movement. Specifically, the position switch 421 is a proximity switch, which can be a photoelectric switch, an inductive switch or a capacitive switch, and the position switch 421 is electrically connected to the motor 32.

[0031] In order to use multiple strip-like protective plates 6 separately, multiple annular grooves 411 are evenly spaced on the paper separation roller 41. The number of the annular grooves 411 is not less than the number of strip-like protective plates 6 formed after the protective plates 6 are cut. The multiple strip-like protective plates 6 are each distributed in the annular grooves 411 to prevent the protective plates 6 from being entangled with each other.

[0032] Principle of the utility model:

[0033] When in use, the protective plate 6 is connected to the use terminal 5 through the cutting unit 2, the traction unit 3 and the paper separation unit 4. As the protective plate 6 is used by the user terminal 5, the protective plate 6 drives the paper separation roller 41 to slide in the track 42. When the paper separation roller 41 approaches the position switch 421 at the top of the track 42, the motor 32 starts and drives the two traction rollers 31 to rotate in opposite directions, pulling the protective plate 6 to move downward. As the remaining amount of the protective plate 6 increases, the paper separation roller 41 returns to the bottom of the track 42. In this process, when the protective plate passes through the cutting unit 2, the blade 23 cuts the entire protective plate 6 into multiple parallel strip-shaped protective plates 6.

[0034] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
