Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment, in particular to a counterweight device for synchronous belt walking of a slurry drawing line. Background Art

[0002] The slurry drawing process is a critical step in the production of nickel-metal hydride batteries. This process involves evenly applying the active material to the negative electrode collector of the battery, usually a foam nickel ribbon. In order to ensure the uniformity of the coating and the performance of the battery, the foam nickel ribbon must pass through the slurry drawing line at a stable speed and tension.

[0003] In the operation of the NiMH battery slurry drawing line, the synchronization performance of the entire line is crucial. The synchronous belt system needs to be precisely controlled to maintain consistent tension throughout the production process to prevent the foam nickel belt from stretching or relaxing. If the tension is not properly controlled, it may lead to reduced battery capacity, increased internal resistance, and even affect the overall life of the battery.

[0004] Traditionally, synchronous belt-feeding systems use air cylinders to balance the weight of the steering roller and the tension of the nickel foam belt. However, since there is a delay in the output force of the air cylinder and the air pressure may be unstable due to system fluctuations, this method cannot provide sufficient accuracy to stably match the weight of the steering roller and the tension of the nickel foam belt. As a result, the nickel foam belt may be stretched due to asynchronous belt-feeding, resulting in a decrease in production quality.

[0005] In order to overcome the above problems, we propose a counterweight device for synchronous belt walking of a slurry pulling line. Summary of the invention

[0006] The utility model aims to solve the shortcomings in the prior art that the foam nickel belt may be elongated due to asynchronous belt running, resulting in a decrease in production quality, and proposes a counterweight device for synchronous belt running of a pulp drawing line.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A counterweight device for synchronous belt conveying of a slurry drawing line is designed, comprising two machine platforms, on which a first transition roller and a second transition roller are respectively arranged;

[0009] Among them, a swing arm is rotatably connected to the side of one of the machine platforms, a steering roller is arranged at one end of the swing arm, and a counterweight is arranged at the other end, and the steering roller is used to change the direction and adjust the tension of the foam nickel strip between the first transition roller and the second transition roller;

[0010] An adjustment mechanism is arranged between the steering roller and the counterweight block and the swing arm.

[0011] Furthermore, the swing arm includes a fixed arm and a connecting arm, the connecting arm is connected to the fixed arm via a fastener, and the steering roller and the counterweight are respectively fixed to the fixed arm and the connecting arm.

[0012] Furthermore, an escape opening is opened on the side of the connecting arm, the fixed arm is penetrated by the rotating shaft on the side of the machine, and a retaining spring is clamped on the rotating shaft.

[0013] Furthermore, the adjustment mechanism includes a transverse waist groove opened on both ends of the swing arm, a sliding seat is slidably connected in the transverse waist groove, and the steering roller and the counterweight block are respectively rotatably set on the two sliding seats, wherein two adjusting screws are respectively threadedly connected at both ends of the swing arm, and the two adjusting screws respectively rotate with the steering roller and the counterweight block to achieve position adjustment.

[0014] Furthermore, it also includes a limiting mechanism fixed on the machine platform, and two limiting mechanisms are provided and symmetrically distributed above and below the swing arm.

[0015] Furthermore, the limiting mechanism includes a fixed seat connected to the machine platform, and a limiting wheel group is fixedly installed on the end surface of the fixed seat, and the limiting wheel group is used to resist the swing arm.

[0016] Furthermore, a rack is embedded on the side of the machine, the fixed seat is slidably connected to the side of the machine, and a limit rod is movably inserted on the fixed seat through a spring, and the end of the limit rod is engaged with the teeth of the rack.

[0017] The utility model proposes a counterweight device for synchronous belt walking of a slurry drawing line, and its beneficial effects are as follows: in the utility model, the counterweight block and the swing arm form a lever mechanism with the rotating shaft of the machine as the fulcrum, and the lever mechanism moves within the range defined by the upper and lower limit mechanisms to avoid the problem of tension mismatch caused by excessive rotation angle of the steering roller. The structure has the characteristics of simple construction and low cost. Secondly, the counterweight block is installed in the transverse waist groove of the swing arm, and the effective force arm length can be changed by moving in the transverse waist groove. The assembly position is adjustable and easy to operate. According to the actual weight of the steering roller and the tension of the foam nickel belt, the counterweight block is moved in the swing arm to adapt to steering rollers of different weights, thereby ensuring synchronous belt walking and preventing the foam nickel belt from being stretched and deformed due to excessive tension. The weight of the steering roller and the tension of the foam nickel in the mechanical counterweight structure are well matched, the belt walking is stable, and the stability of slurry drawing production is improved.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 An embodiment of the utility model discloses a weight counterweight device for synchronous belt-moving of a slurry drawing line, the device comprising two machine platforms 1, on which a first transition roller 2 and a second transition roller 3 are respectively arranged;

[0025] Among them, a swing arm 4 is rotatably connected to the side of one of the machine platforms 1. In this embodiment, the machine platform 1 on the right is taken as an example. A steering roller 5 is provided at one end of the swing arm 4, and a counterweight 6 is provided at the other end. The steering roller 5 is used to change the direction and adjust the tension of the foam nickel belt between the first transition roller 2 and the second transition roller 3.

[0026] An adjustment mechanism 7 is provided between the steering roller 5 and the counterweight block 6 and the swing arm 4 .

[0027] In some embodiments, Figure 2 As shown, the swing arm 4 in this embodiment includes a fixed arm 41 and a connecting arm 42, and the connecting arm 42 is connected to the fixed arm 41 through a fastener, and the steering roller 5 and the counterweight block 6 are respectively fixed to the fixed arm 41 and the connecting arm 42, that is, the fixed arm 41 and the connecting arm 42 in this embodiment are detachably connected, and preferably, the fastener in this embodiment is configured as a bolt, and the fixed arm 41 and the connecting arm 42 can be separated by loosening the bolt during disassembly.

[0028] On the basis of the above embodiment, an avoidance opening 421 is opened on the side of the connecting arm 42, and the avoidance opening 421 is designed to avoid the connecting shaft on the machine 1. The fixed arm 41 is penetrated by the rotating shaft on the side of the machine 1, and a retaining spring 43 is clamped on the rotating shaft. Furthermore, the rotating shaft described in this embodiment is configured as a T-shaped pin shaft, and a ring groove is provided at its end for clamping the retaining spring 43. The purpose of providing the retaining spring 43 is to stop the position of the fixed arm 41 to limit the fixed arm 41 from rotating on the rotating shaft. Thereafter, the connecting arm 42 is fixed to the fixed arm 41 to complete the assembly of the entire swing arm 4. When disassembling, the retaining spring 43 can be loosened to remove the entire swing arm 4 from the above-mentioned rotating shaft.

[0029] In some embodiments, Figure 4 As shown, the adjustment mechanism 7 in the utility model includes a transverse waist groove 71 opened on both ends of the swing arm 4, and a slide seat 72 is slidably connected in the transverse waist groove 71. The steering roller 5 and the counterweight block 6 rotate on the two slide seats 72 respectively, wherein two adjusting screws 73 are threadedly connected at both ends of the swing arm 4, and the two adjusting screws 73 rotate with the steering roller 5 and the counterweight block 6 respectively to achieve position adjustment. In this embodiment, the movable counterweight block 6 is adopted to achieve the adjustment of the counterweight length. According to the lever principle, power × power arm = resistance × resistance arm, which is expressed by an algebraic formula of F1·l1=F2·l2. When the position of the counterweight block 6 is adjusted, the length of the power arm changes, so it can conveniently and stably ensure synchronous belt running and will not be deformed due to excessive tension stretching the nickel foam belt.

[0030] That is, in this embodiment, the position of the slide 72 can be changed by rotating the adjusting screw 73, so that the positions of the steering roller 5 and the counterweight block 6 can be adaptively adjusted. Specifically, a rotating shaft is also provided on the steering roller 5 and the counterweight block 6, and the rotating shaft can also be stopped and limited by a retaining spring to achieve a convenient disassembly effect. In addition, in this embodiment, limiting plates are provided on both sides of the slide 72 to limit the slide 71 from sliding in the transverse waist groove 71.

[0031] In addition, considering limiting the swing angle of the swing arm 4 to avoid the problem of excessive or insufficient tension caused by excessive swing angle, the utility model also includes a limiting mechanism 8 fixed on the machine 1, and two limiting mechanisms 8 are provided and symmetrically distributed above and below the swing arm 4.

[0032] Further, such as Figure 2As shown, the limiting mechanism 8 in this embodiment includes a fixed seat 81 connected to the machine 1, and a limiting wheel group 82 is fixedly installed on the end surface of the fixed seat 81, and the limiting wheel group 82 is used to resist the swing arm 4, that is, the limiting wheel group 82 provided in this embodiment is used to stop the upward or downward rotation of the swing arm 4, which can stably ensure the synchronous belt running and will not be deformed by stretching the foam nickel belt due to excessive tension. Furthermore, the limiting wheel group 82 in this embodiment may include a wheel frame and a roller rotating on the wheel frame, wherein the wheel frame is fixedly mounted on the fixed seat 81.

[0033] Of course, in order to achieve the adaptability adjustment of the upper and lower limit amplitudes, such as Figure 2 and Figure 3 As shown, a rack 83 is also embedded on the side of the machine 1 in this embodiment, and the fixed seat 81 is slidably connected to the side of the machine 1. The sliding method can adopt the cooperation method of the guide rail and the slider, and the fixed seat 81 is movably inserted with a limit rod 85 through a spring 84, and the end of the limit rod 85 is engaged with the teeth of the rack 83. Specifically, when it is necessary to adjust the upper and lower limits, the limit rod 85 can be pulled outward, and then the end of the limit rod 85 is separated from the rack 83, and the fixed seat 81 can be freely slid to achieve position adjustment. After the adjustment is completed, the force on the limit rod 85 is released, and when the limit rod 85 is engaged with the rack 83, the position positioning is completed.

[0034] In summary, the counterweight block 6 and the swing arm 4 described in this embodiment form a lever mechanism with the rotating shaft of the machine 1 as the fulcrum. The lever mechanism operates within the range defined by the upper and lower limit mechanisms 8 to avoid the problem of tension mismatch caused by excessive rotation angle of the steering roller 5. This structure has the characteristics of simple structure and low cost. Secondly, the counterweight block 6 is installed in the transverse waist groove 71 of the swing arm 4. By moving in the transverse waist groove 71, the effective force arm length can be changed. The assembly position is adjustable and easy to operate. According to the actual weight of the steering roller 5 and the tension of the foam nickel belt, the counterweight block 6 is moved in the swing arm 4 to adapt to steering rollers of different weights, ensuring synchronous belt running and not deforming the foam nickel belt due to elongation of excessive tension. The weight of the steering roller 5 and the tension of the foam nickel in this mechanical counterweight structure are well matched, the belt running is stable, and the stability of the slurry pulling production is improved.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
