Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of battery pole piece slitting, and particularly relates to a front pressure rod device of a slitting knife frame. Background Art
[0002] Battery electrode slitting requires a slitting knife and a slitting knife holder. Currently, the front pressure bar installed in front of the slitting knife holder can only move up and down, not forward or backward. Furthermore, during the electrode slitting process, the pressure bar is far from the slitting knife, making it unable to effectively stabilize the electrode as it enters the slitting knife. This results in excessive fluctuations in the electrode when the slitting knife is slitting, affecting the electrode slitting effect. Utility Model Content
[0003] The utility model provides a front pressure rod device for a slitting knife holder, which enables the front pressure rod device of the slitting knife to be adjusted in the horizontal and vertical directions according to different electrode sizes, thereby solving the deficiencies described in the background technology.
[0004] The technical solution adopted by this utility model is:
[0005] A front pressure rod device for a slitting blade holder includes a front pressure rod structure, a first movable structure, and a second movable structure; the front pressure rod structure includes a central fixed rod, a front pressure rod, and a bearing; a second movable structure is installed at each end of the central fixed rod, and the front pressure rod is mounted on the central fixed rod via a bearing sleeve, and the front pressure rod rotates relative to the central fixed rod; each second movable structure is mounted on a corresponding first movable structure and moves with the first movable structure; the moving direction of the first movable structure is perpendicular to the moving direction of the second movable structure. The front pressure rod can rotate around the central fixed rod under the action of the bearing, and realizes rotational pressure feeding driven by the pole piece conveying force, and the setting of the two-directional movable structures allows the front pressure rod to be adjusted in both the vertical and horizontal directions to change the distance from the slitting blade.
[0006] As a preferred embodiment of the present invention, the first movable structure includes a screw and a movable slider. The movable slider has a threaded hole, through which the screw is inserted and threadedly connected. The second movable structure is adjustably mounted on the movable slider. The screw has an external thread that is threadedly connected to the internal thread of the threaded hole. Since the movable slider is restrained by the central fixed rod and cannot rotate, the screw is rotated, which causes the movable slider to move up and down on the screw, thereby achieving vertical adjustment of the front pressure rod.
[0007] As a preferred solution of the present invention, the movable slider is provided with a track groove for the movement of the second movable structure. The track groove is provided for the purpose of installing the second movable structure on the one hand, and for limiting the movement of the second movable structure on the other hand.
[0008] As a preferred embodiment of the present invention, the movable slider is provided with a locking hole that is perpendicular to the track slot. When the second movable structure changes its position within the track slot, the locking hole and locking pin secure the second movable structure. The second movable structure changes the horizontal spacing between the front pressure rod and the slitting blade, thereby reducing fluctuations in the gap between the pole piece and the slitting blade, thereby improving slitting quality.
[0009] As a preferred solution of the present invention, the second movable structure includes a movable slider I, which is movably installed in the track groove, and the end of the central fixed rod is installed on the movable slider I.
[0010] As a preferred solution of the present invention, the movable slider I is provided with a fixed rod assembly hole and a tightening hole, the tightening hole is vertically connected to the fixed rod assembly hole, and the tightening piece is threadedly installed in the tightening hole and tightens the center fixed rod in the fixed rod assembly hole.
[0011] As a preferred solution of the present invention, the movable slider is slidably mounted on a fixed mounting block, which is used to mount the entire device on the slitting blade holder.
[0012] As a preferred solution of the present invention, the fixed mounting block is provided with a limiting track groove, and the setting direction of the limiting track groove is parallel to the screw rod; the end of the movable slider connected to the screw rod and the screw rod are both set in the limiting track groove, and the screw rod is exposed upward from the limiting track groove.
[0013] The utility model realizes the adjustment of the horizontal and vertical positions of the front pressure rod through the first movable structure and the second movable structure, which can solve the fluctuation situation when different pole pieces are cut by the slitting knife. The position of the front pressure rod is adjusted according to different pole pieces, and the distance between the pole piece gap and the slitting knife is shortened, so that the fluctuation of the pole piece when the gap passes through the slitting knife is reduced, the slitting quality is improved, and the generation of burrs and electrical material abnormalities is reduced.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] Example:
[0019] A front pressure rod device for a slitting tool holder comprises a front pressure rod structure 1, a first moving structure 2 and a second moving structure 3.
[0020] The front pressure rod structure 1 includes a central fixed rod 11, a front pressure rod 12, and a bearing 13; a second movable structure 3 is installed on both ends of the central fixed rod 11, and the front pressure rod 12 is sleeved on the central fixed rod 11 through the bearing 13. The front pressure rod 12 rotates relative to the central fixed rod 11, and the bearing is fixed to the central fixed rod through a fixed top screw.
[0021] Each second movable structure 3 is mounted on the corresponding first movable structure 2 and moves with it; the movement direction of the first movable structure 2 is perpendicular to that of the second movable structure 3. The front pressure rod, driven by the bearing, can rotate around the central fixed rod, achieving rotational pressure feeding driven by the electrode conveying force. The dual-directional movable structure allows the front pressure rod to be adjusted in both vertical and horizontal directions to change its distance from the slitting blade.
[0022] Specifically, the first movable structure 2 includes a screw rod 21 and a movable slider 22. The movable slider 22 is provided with a threaded hole. The screw rod 21 is set through the threaded hole of the movable slider 22 and is threadedly connected to the threaded hole. The rotating screw rod is converted into the up and down movement of the movable slider on the screw rod because the movable slider is limited by the central fixed rod and cannot rotate, thereby realizing the adjustment of the front pressure rod in the vertical direction.
[0023] To secure the second movable structure, locking holes are provided on the movable slider 22. In this embodiment, locking holes are provided on both the upper and lower surfaces of the movable slider, and the locking holes are perpendicular to the track slot. When the second movable structure changes its position within the track slot, the locking holes and locking pins secure the second movable structure. This second movable structure changes the horizontal spacing between the front pressure bar and the slitting blade, reducing fluctuations in the gap between the pole piece and the slitting blade, thereby improving slitting quality.
[0024] The second movable structure includes a movable slider I31, which is movably installed in the track groove. The end of the central fixed rod 11 is installed on the movable slider I31. Specifically, the movable slider I31 is provided with a fixed rod assembly hole and a tightening hole. The tightening hole is vertically connected to the fixed rod assembly hole. The tightening piece is threadedly installed in the tightening hole and tightens the central fixed rod in the fixed rod assembly hole.
[0025] After overall assembly, each movable slider is fitted with a fixed mounting block 4 for attachment to the slitting tool holder. This fixed mounting block 4 is provided with a limiting track slot, which is arranged parallel to the screw. The ends of the movable sliders where they connect to the screw and the screw are both positioned within the limiting track slot, with the screw protruding upwards from the limiting track slot. For ease of installation, the movable sliders are convex, with the ends with threaded holes extending into the limiting track slots. Both the movable sliders 1 and the track slots are positioned outside of the limiting track slots.
[0026] After the fixed mounting block is installed on the slitting tool holder, adjust the screw rod so that the center point of the movable slider I31 is in the middle position of the tool holder measuring ruler to facilitate later adjustment.
