Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery manufacturing technology, and in particular relates to a traction ring mechanism for continuous coating of lead-acid batteries. Background Technology

[0002] During the continuous coating process of lead-acid batteries, the grid mesh belt passes through the coating machine head, where lead paste is applied to the grid mesh belt to form a strip of wet electrode plate. The strip of wet electrode plate with lead paste is then cut into individual electrode plates by a slitting knife. During the slitting process, a traction ring is used for positioning, and the traction ring is fixed to the lower roller of the slitting knife by screws.

[0003] During production, it was discovered that progressively deepening blade marks form at the contact area between the slitting blade and the lower slitting roller during continuous operation. This damage is caused by two key factors: First, the relative position of the contact surfaces between the slitting blade and the lower slitting roller is fixed. This fixed position is due to the traction ring being fixed to the lower slitting roller, resulting in a rigid constraint on the relative position of the contact surfaces between the slitting blade and the lower slitting roller. Second, during the slitting operation, the blade and the lower roller experience a stress concentration effect. When the depth of the blade marks exceeds a critical threshold, it will cause quality defects such as incomplete slitting of the electrode plate or failure to cut the coated paper.

[0004] The core problem with this structure is that the relative position of the slitting blade and the lower slitting roller is fixed due to the traction ring, making it impossible to adjust. This results in the inability to avoid the damage area caused by blade marks, ultimately leading to the complete scrapping of the lower slitting roller. Statistical data shows that the average service life of this non-adjustable lower slitting roller is only about 12 months, significantly increasing equipment maintenance costs and affecting production continuity. Utility Model Content

[0005] The purpose of this invention is to provide a traction ring mechanism for continuous coating of lead-acid batteries, so as to solve the problem that the relative position of the slitting blade and the lower roller of the slitting blade is not adjustable due to the fixation of the traction ring in the prior art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A traction ring mechanism for continuous coating of lead-acid batteries includes a slitting lower roller, a traction ring sleeved outside the slitting lower roller, and a slitting blade disposed above the slitting lower roller. The traction ring includes two opposing traction half-rings, which surround each other to form a circular ring structure.

[0011] Furthermore, a positioning monitoring assembly is also provided on the side of the lower roller of the slitting knife;

[0012] The positioning and monitoring assembly includes a traction ring auxiliary limiting mechanism and a support plate. There are two support plates, which are arranged opposite to each other. The traction ring auxiliary limiting mechanism is located between the two support plates.

[0013] The traction ring auxiliary limiting mechanism is used to push the traction ring to move outside the lower roller of the slitting cutter.

[0014] Furthermore, the traction ring auxiliary limiting mechanism includes a bottom support, a limiting guide rail, and a mounting base. The bottom support is fixedly disposed between two bearing plates, the limiting guide rail is disposed on the top of the bottom support, and the bottom of the mounting base is slidably disposed outside the limiting guide rail.

[0015] The mounting base is provided with clamping and limiting plates at its left and right ends, and a limiting area is formed between the two clamping and limiting plates to cooperate with the traction ring.

[0019] Furthermore, the driving mechanism is an electric push rod or a cylinder.

[0020] Furthermore, a laser ranging mechanism for cutting marks is also provided on the side of the lower roller of the slitting knife.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] like Figures 1 to 4 As shown, a traction ring mechanism for continuous coating of lead-acid batteries includes a slitting lower roller 1, a traction ring 2 sleeved outside the slitting lower roller 1, and a slitting blade 3 disposed above the slitting lower roller 1. The traction ring 2 includes two opposing traction half-rings 21, which surround each other to form a circular structure.

[0034] Both ends of the traction half-ring 21 are provided with mounting grooves 22, and the bottom of the mounting grooves 22 is provided with threaded holes 221. The two threaded holes 221 that are close to each other on the two traction half-rings 21 are connected, and bolts 23 are provided in the two threaded holes 221 that are close to each other on the two traction half-rings 21. The two traction half-rings 21 are connected by bolts 23, that is, the two traction half-rings 21 are detachably connected by bolts 23.

[0035] The lead-acid battery continuous coating traction ring mechanism improves upon the original traction ring by using two semi-circular traction half-rings 21 to form a circular traction ring 2. Specifically, the two traction half-rings 21 are detachably connected by bolts 23. This detachable connection method includes, but is not limited to, using bolt connection. That is, the two traction half-rings 21 are detachably connected by bolts. In actual use, the inner diameter of the traction ring is reduced by tightening screws and tightened onto the lower roller 1 of the slitting knife, instead of fixing it to the lower roller of the slitting knife with screws.

[0036] When the knife marks on the lower roller 1 of the slitting blade 3 are relatively deep, loosen the bolts on the two traction half-rings 21, rotate the traction ring 2 appropriately, and adjust the relative position of the traction ring 2 and the lower roller 1 of the slitting blade to offset the existing knife marks. Then tighten the bolts on the two traction half-rings 21. This will still ensure the normal use of the traction ring 2, and the service life of the lower roller 1 of the slitting blade will be significantly extended, by at least 2 years.

[0037] like Figures 1 to 4 As shown, in some embodiments of this utility model, the outer circumferential surface of the traction half-ring 21 is evenly distributed with positioning protrusions 24; the traction half-ring 21 is positioned during lead paste cutting through the positioning protrusions 24.

[0038] like Figures 1 to 4As shown, in some embodiments of this utility model, there are 3 traction rings 2, which are respectively located at the left end, right end and center position outside the lower roller 1 of the slitting knife;

[0039] When adjusting the position of the traction rings, the positions of the three traction rings 2 can be adjusted one by one.

[0040] like Figures 1 to 4 As shown, in some embodiments of this utility model, a lead paste slitting gap 200 is formed between the slitting blade 3 and the lower roller 1 of the slitting blade;

[0041] The lead paste slitting gap 200 is used for slitting lead paste. Specifically, during actual installation and use, the slitting blade is installed on the slitting drive equipment, which can drive the slitting blade to rotate. During cutting, the strip of wet electrode plate coated with lead paste passes through the lead paste slitting gap 200 and is slitted into single electrode plates by the rotation of the slitting blade above. The slitting is positioned by a traction ring, which is fixed to the lower roller of the slitting blade by screws.

[0042] like Figures 1 to 4 As shown, in some embodiments of this utility model, a positioning monitoring assembly 100 is also provided on the side of the lower slitting roller 1; the positioning monitoring assembly 100 can be provided on the side of the lower slitting roller 1 so as not to affect the actual operation of the lower slitting roller 1.

[0043] The positioning monitoring assembly 100 includes a traction ring auxiliary limiting mechanism 4 and a bearing plate 6. There are two bearing plates 6, which are arranged opposite to each other. The traction ring auxiliary limiting mechanism 4 is located between the two bearing plates 6.

[0044] The traction ring auxiliary limiting mechanism 4 is used to push the traction ring 2 to move outside the slitting cutter lower roller 1;

[0045] A positioning monitoring assembly 100 is also provided on the side of the lower roller 1 of the slitting blade. The positioning monitoring assembly 100 can be installed according to the installation position of the lower roller 1 of the slitting blade. For example, the lower roller 1 of the slitting blade is generally installed on the frame to ensure the relative rotation of the lower roller 1 of the slitting blade and the slitting blade 3. The positioning monitoring assembly 100 can be installed on the frame for auxiliary positioning of the traction ring 2.

[0046] like Figures 1 to 4 As shown, in some embodiments of this utility model, the traction ring auxiliary limiting mechanism 4 includes a bottom support 41, a limiting guide rail 42, and a mounting base 43. The bottom support 41 is fixedly disposed between two bearing plates 6, the limiting guide rail 42 is disposed on the top of the bottom support 41, and the bottom of the mounting base 43 is slidably disposed outside the limiting guide rail 42.

[0047] The left and right ends of the mounting base 43 are provided with clamping and limiting plates 44, and the two clamping and limiting plates 44 form a limiting area 45 that cooperates with the traction ring 2.

[0048] The auxiliary limiting mechanism 4 of the traction ring is suitable for the auxiliary positioning of the traction ring 2. Specifically, before adjusting the position of the traction ring 2, two clamping limiting plates 44 are placed outside the traction ring 2 so that the traction ring 2 is tightly placed between the two clamping limiting plates 44. Then, the bolts on the two traction half rings 21 are loosened, and the position of the traction half ring 21 is adjusted by adjusting the position of the mounting seat 43 on the limiting guide rail 42.

[0049] During the above process, since the traction ring auxiliary limiting mechanism 4 is located on the side of the lower roller 1 of the slitting knife, it has a certain operating space and the operation and adjustment are relatively convenient and reliable.

[0050] like Figures 1 to 4 As shown, in some embodiments of this utility model, the upper end of the mounting base 43 is provided with a shaft hole, a damping rotating shaft 46 is provided in the shaft hole, and the clamping and limiting plate 44 is provided with a mounting hole that cooperates with the damping rotating shaft 46.

[0051] The left end of the damping shaft 46 passes through the mounting hole and is equipped with a knob 461;

[0052] By providing a damping shaft 46 inside the shaft hole, the damping shaft 46 is inserted into the shaft hole to provide rotational resistance and ensure the automatic locking position after rotation without the need for additional locking steps; after the left end of the damping shaft 46 extends out of the mounting hole, a knob 461 is also provided, which can be used to rotate the damping shaft 46, making it more effortless.

[0053] like Figures 1 to 4 As shown, in some embodiments of this utility model, a drive mechanism 47 is provided on the bearing plate 6 located at the left end of the bottom support 41. The output end of the drive mechanism 47 is connected to the mounting base 43. The drive mechanism 47 is used to drive the mounting base 43 to slide on the limiting guide rail 42.

[0054] The drive mechanism 47 can be an electric push rod or a cylinder, and the drive mechanism 47 is preferably an electric push rod; the mounting base of the drive mechanism 47 is fixedly installed on the bearing plate 6 located at the left end of the bottom support 41, and the output end of the drive mechanism 47 is fixedly connected to the mounting base 43.

[0055] This setup allows for precise adjustment of the position of the traction ring 2.

[0056] like Figures 1 to 4As shown, in some embodiments of this utility model, a cutting laser ranging mechanism 5 is also provided on the side of the slitting lower roller 1. The cutting laser ranging mechanism 5 includes a mounting base 51, a laser rangefinder 52, and a linear guide rail. The laser rangefinder 52 is located at the center of the top of the mounting base 51, and the mounting base 51 is located at the output end of the linear guide rail. The mounting end of the linear guide rail is provided with a mounting bracket. The cutting laser ranging mechanism 5 can be located on the side of the slitting lower roller 1, so as not to affect the actual operation of the slitting lower roller 1. Specifically, the installation positions of the cutting laser ranging mechanism 5 and the positioning monitoring assembly 100 do not interfere with each other.

[0057] Among them, a laser ranging mechanism 5 for measuring cuts is provided on the side of the lower roller 1 of the slitting knife. The laser ranging mechanism 5 for measuring cuts can be installed according to the installation position of the lower roller 1 of the slitting knife. For example, the lower roller 1 of the slitting knife is generally installed on the frame to ensure the relative rotation of the lower roller 1 of the slitting knife and the slitting knife 3. The laser ranging mechanism 5 for measuring cuts can be installed on the frame to monitor the degree of wear of the cuts.

[0058] The plane of the longitudinal section of the slitting blade 3 coincides with the optical axis of the laser rangefinder 52;

[0059] The traction ring auxiliary limiting mechanism 4 is located outside the linear guide rail;

[0060] Specifically, the longitudinal section of the slitting blade 3 refers to the section along the radial direction of the slitting blade 3, and the longitudinal section of the slitting blade 3 is parallel to the left side of the slitting blade 3; the optical axis of the laser rangefinder 52 refers to the central axis of laser emission and reception, that is, the reference line for ranging;

[0061] The plane of the longitudinal section of the slitting blade 3 coincides with the optical axis of the laser rangefinder 52, meaning that the optical axis of the laser rangefinder 52 is completely located within the plane of the longitudinal section of the slitting blade 3, forming a coplanar relationship.

[0062] The laser ranging mechanism 5 for cutting marks can be installed according to the installation position of the lower roller 1 of the slitting knife. For example, the lower roller 1 of the slitting knife is generally installed on the frame to ensure the relative rotation of the lower roller 1 of the slitting knife and the slitting knife 3. The laser ranging mechanism 5 for cutting marks can be installed on the frame. Specifically, the mounting bracket of the linear guide rail on the laser ranging mechanism 5 for cutting marks can be installed on the frame, so as not to affect the rotation of the lower roller 1 of the slitting knife, and is used to monitor the knife marks produced by the slitting knife 3 on the lower roller 1 of the slitting knife.

[0063] The purpose of the above settings is as follows:

[0064] First, the initial distance between the laser rangefinder 52 and the lower slitting roller 1 is set as the reference value d1. During equipment operation, as the contact area between the slitting blade 3 and the lower slitting roller 1 continues to operate, progressively deepening blade marks will gradually form in the contact area. Due to the presence of these blade marks, the real-time monitoring distance (marked as d2) between the laser rangefinder 52 and the lower slitting roller 1 will dynamically change. By continuously tracking the fluctuations in the value of d2 and calculating the difference between it and the initial reference value d1 (Δd = d2 - d1), the actual depth of the current blade mark can be calculated in real time. When the depth of the blade mark reaches a preset safety threshold, the system will trigger an early warning prompting the operator to adjust the traction ring 2. Since the traction ring 2 directly controls the slitting positioning of the slitting blade 3 in the roller axis direction, adjusting its position can shift the contact point of the slitting blade 3 away from the original blade mark area, thereby achieving periodic rotation of the contact position and effectively avoiding excessive local wear.

[0065] like Figures 1 to 4 As shown, in some embodiments of this utility model, the linear guide rail is a linear actuator;

[0066] The linear actuator can be a lead screw mechanism, and the mounting base 51 is detachably mounted on the nut slider of the lead screw mechanism; specifically, the mounting base 51 can be fixed to the nut slider of the lead screw mechanism by bolt connection.

[0067] A lead screw mechanism (also known as a lead screw transmission mechanism) is a mechanical device that converts rotary motion into linear motion (or vice versa). It is existing technology and will not be elaborated on here.

[0068] This utility model provides a traction ring mechanism for continuous coating of lead-acid batteries. The traction ring 2, as a key positioning component, features an innovative structural design that effectively solves the problem of the unadjustable relative position between the slitting blade 3 and the lower slitting roller 1 due to the fixed traction ring. This design avoids the original blade marks between the slitting blade 3 and the lower slitting roller 1. Specifically, during prolonged slitting, characteristic blade marks are generated in the contact area between the slitting blade 3 and the lower slitting roller 1. The detachable design of the traction ring 2 allows for a change in its axial position on the lower slitting roller 1, causing a displacement in the contact area. This ensures that the displaced contact area completely avoids the original blade mark position, thus preventing quality defects such as incomplete plate slitting or incomplete cutting of the coating paper due to excessively deep blade marks. Using the traction ring mechanism for continuous coating of lead-acid batteries provided by this utility model significantly extends the service life of the lower slitting roller 1, significantly reduces equipment maintenance costs, and effectively promotes production continuity.
