Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, and in particular to a limiting device for a lead belt extension device for a lead-acid battery. Background Technology

[0002] Lead-acid batteries are rechargeable batteries whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. In the discharged state, the positive electrode is mainly composed of lead dioxide, and the negative electrode is mainly composed of lead; in the charged state, both the positive and negative electrodes are mainly composed of lead sulfate.

[0003] In the manufacturing of lead-acid batteries, there is a step called grid fabrication, which requires expanding and drilling holes in the pre-prepared lead strips. While the equipment for expanding lead strips is relatively mature, the following problems still exist in actual production and use:

[0004] 1. When the lead strip enters the expansion equipment for expansion, the entire equipment vibrates significantly, and the expanded lead strip is relatively thin. During the vibration, the expanded lead strip is prone to shifting, which not only damages the edges of the lead strip but also makes subsequent discharge difficult.

[0005] 2. Conventional limiting devices are set on both sides of the worktable and fixed by bolts or pins. However, in the extension of various specifications of lead strips, the position of the limiting plates also needs to be changed according to different models. Using bolts and pins is not only easy to loosen, but also inconvenient for subsequent movement. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a limiting device for the lead belt extension device of a lead-acid battery, which effectively solves the problems mentioned in the background art.

[0007] The technical solution is as follows: This utility model includes a support base, a worktable placed on top of the support base, and an extension component placed above the worktable. Guide plates are fixed at both the front and rear ends of the worktable, and mounting plates are fixedly connected to both the left and right sides of the worktable. Limiting plates slide back and forth on the mounting plates, and cavities are opened in the limiting plates. Limiting blocks are fixedly connected to the limiting plates, and T-shaped limiting grooves are opened on both sides of the sliding groove on the mounting plates. Two T-shaped limiting blocks that match the T-shaped limiting grooves are fixed on the limiting plates.

[0008] The mounting plate has a sliding groove, and a rack is provided in the sliding groove. The limiting plate has a rectangular groove on one side near the mounting plate, which corresponds to the sliding groove. A fixing post is provided inside the cavity, and a limiting gear is rotatably connected to the fixing post. The limiting gear passes through the rectangular groove and meshes with the rack.

[0009] Preferably, the limiting gear has multiple circumferentially distributed limiting holes, a connecting plate is fixed on the fixing column, a limiting rod matching the limiting holes is slidably connected to the connecting plate, a contact plate is fixed to the end of the limiting rod away from the limiting holes, the contact plate and the connecting plate are connected by a spring, a moving rod perpendicular to one side of the limiting rod is provided, connecting blocks are fixed to both sides of the limiting plate, the moving rod and the connecting blocks are slidably connected, a conical block is coaxially fixed on the moving rod, the conical block contacts the contact plate, a spring plate is coaxially fixed on the moving rod, and the spring plate and the adjacent connecting block are connected by a spring.

[0010] Preferably, a pointer is fixed to one side of the limiting plate, and a scale bar is provided on the mounting plate.

[0011] Preferably, a handle is fixed to one end of the moving rod.

[0012] Preferably, a plurality of mounting cylinders are fixed on the mounting plate, and the mounting cylinders are fixedly connected to the workbench by bolts or pins.

[0013] Preferably, a protective cover is fixed on the support base, and opening doors are provided on both the left and right sides of the protective cover. An inlet and an outlet are respectively provided on the front and rear sides of the protective cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Limiting plates, limiting blocks, and mounting plates are used to limit the lead strip on the workbench to prevent the extended lead strip from easily shifting during vibration, which would not only damage the edge of the lead strip but also make subsequent material discharge inconvenient.

[0016] 2. With the setting of limiting holes, limiting rods and moving rods, when the limiting plate needs to move, simply press the moving rod to one side, and the conical block will disengage from the contact plate. At this time, the limiting rod will disengage from the limiting hole under the action of the spring, realizing the rapid movement of the limiting block. At the same time, the limiting rod is inserted into the inside of the limiting hole, so it will not disengage from the inside of the limiting hole even under vibration, thus improving the stability of the limiting plate.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Depend on Figures 1 to 4The worktable includes a support base 10, a worktable 20 placed on top of the support base 10, and an extension component 30 placed above the worktable 20. The extension component 30 is conventional prior art and will not be described in detail here. Guide plates 40 are fixed at both the front and rear ends of the worktable 20. The two guide plates 40 are used to assist in the feeding and discharging of the lead strip, which has finished expanding during discharging. Mounting plates 60 are fixedly connected to both the left and right sides of the worktable 20. Limiting plates 61 slide back and forth on the mounting plates 60 to prevent displacement during vibration. In this embodiment, since the sides of the worktable 20 are conical, the limiting plates 61 are triangular in shape and have cavities. Limiting blocks 61 are fixedly connected to the limiting plates 61. 1. A limiting block 611 is used to limit the lead strip on the workbench 20. The limiting block 611 is located on the top of the limiting plate 61. At the same time, in order to facilitate the limiting and disassembly between the limiting plate 61 and the mounting plate 60, the mounting plate 60 is provided with T-shaped limiting grooves 602 located on both sides of the slide groove. Two T-shaped limiting blocks 613 matching the T-shaped limiting grooves 602 are fixed on the limiting plate 61. With the setting of the T-shaped limiting grooves 602 and T-shaped limiting blocks 613, when the limiting plate 61 moves on the mounting plate 60, the T-shaped limiting grooves 602 and T-shaped limiting blocks 613 can limit it. At the same time, when the limiting plate 61 or its internal components are damaged and need to be replaced, it is only necessary to pull the limiting plate 61 to one side and slide it completely out of the limiting range of the T-shaped limiting grooves 602.

[0026] The mounting plate 60 has a sliding groove, and a rack 601 is installed in the sliding groove. The limiting plate 61 has a rectangular groove 614 on one side near the mounting plate 60, which corresponds to the sliding groove. A fixing post 62 is installed inside the cavity, and a limiting gear 63 is rotatably connected to the fixing post 62. The limiting gear 63 passes through the rectangular groove 614 and meshes with the rack 601. Through the rack 601, the limiting gear 63, and the limiting block 611, the lead strip on the workbench 20 is limited to avoid damage to the lead strip caused by displacement during vibration.

[0027] refer to Figures 4 to 5As shown, considering that the limiting plate 61 needs to move according to different models of lead belts, fixing it with bolts or pins is not only prone to loosening, but also makes subsequent disassembly and movement quite troublesome. The limiting gear 63 has multiple circumferentially distributed limiting holes 631. A connecting plate 65 is fixed to the fixing post 62. A limiting rod 64 matching the limiting holes 631 is slidably connected to the connecting plate 65. A contact plate 641 is fixed to the end of the limiting rod 64 away from the limiting holes 631. The contact plate 641 and the connecting plate 65 are connected by a spring. A moving rod 66 perpendicular to the limiting rod 64 is provided on one side. Connecting blocks 615 are fixed to both sides of the limiting plate 61. The moving rod 66 is slidably connected to the connecting blocks 615. A conical block 661 is coaxially fixed on the moving rod 66, and the conical block 661 contacts the contact plate 641. A spring plate 662 is coaxially fixed on the moving rod 66, and the spring plate 662 is connected to the adjacent connecting block 615 by a spring. With the setting of limiting hole 631, limiting rod 64 and moving rod 66, when it is necessary to move the limiting plate 61, simply press the moving rod 66 to one side, and the conical block 661 will disengage from the contact plate 641. At this time, the limiting rod 64 will disengage from the limiting hole 631 under the action of the spring, realizing the rapid movement of the limiting block 611. At the same time, the limiting rod 64 is inserted into the inside of the limiting hole 631, and will not disengage from the inside of the limiting hole 631 even under vibration, thus improving the stability of the limiting plate 61.

[0028] refer to Figure 2 and Figure 3 As shown, considering that limit plates 61 are provided on both sides of the workbench 20, the moving distance of the limit plates 61 on both sides needs to be kept as consistent as possible. A pointer 612 is fixed on one side of the limit plate 61, and a scale bar 603 is provided on the mounting plate 60. The operator can adjust the limit plates 61 on both sides by referring to the pointer 612 and the scale bar 603.

[0029] refer to Figure 5 As shown, in order to facilitate workers to press the movable rod 66, a handle 663 is fixed to one end of the movable rod 66.

[0030] refer to Figure 3 As shown, multiple mounting cylinders 604 are fixed on the mounting plate 60. The mounting cylinders 604 are fixedly connected to the worktable 20 by bolts or pins. Since the mounting plate 60 does not need to be moved frequently on the worktable 20, the existing fixing method is sufficient.

[0031] refer to Figure 1As shown, a protective cover 50 is fixed on the support base 10 to isolate some noise and protect the safety of workers. The protective cover 50 has opening doors on both the left and right sides. The opening doors are normally closed during operation and are opened for adjustment when the two limit plates 61 need to be adjusted. The protective cover 50 has a feed inlet and a discharge outlet on the front and rear sides respectively.

[0032] When using this utility model:

[0033] First, the unextended lead strip is inserted into the feed side of the worktable 20. As the lead strip continues to go deeper, it is continuously extended by the extension component 30. The limiting plates 61 and limiting blocks 611 on the left and right sides of the worktable 20 limit the lead strip.

[0034] Then, for different models and specifications of lead strip expansion, the limiting plate 61 needs to be moved along the workbench 20. Before moving, the worker only needs to press the handle 663 to drive the moving rod 66 to slide to one side. At this time, the cone block 661 disengages from the contact plate 641, and the limiting rod 64 disengages from the limiting hole 631 under the action of the spring. Then the limiting plate 61 can be moved.

[0035] Secondly, when the worker stops pressing the handle 663, the moving rod 66 returns to its original position under the action of the spring, and the cone block 661 abuts against the contact plate 641 again, so that the limiting rod 64 is inserted into the limiting hole 631 again.

[0036] Finally, during the movement of the two limit plates 61, the worker needs to refer to the scale bar 603 to ensure that the movement distance of the two limit plates 61 remains consistent.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
