Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and specifically relates to a lead blank temperature detection mechanism. Background Art

[0002] The main component of a battery is the electrode plate. The production of the electrode plate first involves producing a lead strip-shaped lead blank, forming a grid through a wire drawing technique or punching, and then performing paste mixing, grid coating, and curing and drying to form the electrode plate.

[0003] One of the failure modes of a battery is grid corrosion. In addition to being affected by the alloy composition, the corrosion resistance of the grid is also affected by the temperature of the lead blank. Through experimental research, it is found that the lower the temperature of the lead blank during the production of the electrode plate, the better the corrosion resistance of the grid.

[0004] The lead blank is formed into a lead strip from lead liquid with a temperature above 330°C, and then rapidly cooled and solidified by means of water spraying. After the cooling treatment, the temperature of the lead blank is generally between 70 - 80°C. To ensure the processing quality of the electrode plate, it is particularly important to monitor the temperature of the lead blank. However, in the existing lead blank temperature device, the temperature measuring element is usually fixedly installed at the feeding end of the lead blank roller conveyor, and the spacing and angle of the temperature measuring elements are not easy to adjust, which is not suitable for uniformly monitoring the temperature of lead blanks with different widths. Therefore, it is urgently needed to be improved. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above technical problems, and the following technical solutions are proposed:

[0006] A lead blank temperature detection mechanism includes a lead blank roller conveyor, a limit connecting piece, and a temperature measuring guide plate rotatably connected between the two side brackets of the lead blank roller conveyor. The limit connecting piece can limit the inclination angle of the temperature measuring guide plate on the two side brackets. A long strip-shaped guide groove is opened on the temperature measuring guide plate. The length direction of the guide groove is consistent with the width direction of the lead blank on the lead blank roller conveyor, and the groove length of the guide groove matches the maximum width of the lead blank that can be conveyed on the lead blank roller conveyor. A plurality of temperature measuring probes that can be slidably adjusted along the length direction of the guide groove are arranged in the guide groove.

[0007] Preferably, an annular fixed clip is sleeved on the upper part of the temperature measuring probe, and an annular movable clip is threadedly connected to the lower part of the temperature measuring probe. The outer diameters of the fixed clip and the movable clip are both larger than the groove width of the guide groove, and the diameter of the temperature measuring probe is smaller than the groove width of the guide groove. By loosening or tightening the movable clip, the spacing of the temperature measuring probes can be conveniently adjusted, and the temperature measuring probes can be limited on the guide groove.

[0008] Preferably, the model of the temperature measuring probe is PT100.

[0009] Preferably, the limit connecting member includes two corresponding toggle bolts that are slidably inserted through the brackets on both sides, and screw holes are centrally provided at both ends of the temperature measuring guide plate for threaded connection with the corresponding toggle bolts. By loosening the toggle bolts, the tilt angle of the temperature measuring guide plate can be adjusted, and thus the angle of the temperature measuring probe can be adjusted. After adjustment, by tightening the toggle bolts, the tilt angle of the temperature measuring guide plate can be limited.

[0010] Preferably, the number of the temperature measuring probes is 3 to 4, and they are evenly distributed along the width direction of the lead billet.

[0011] The present utility model further includes other devices or components that enable its normal use, which are all conventional technical means in the art; in addition, the devices or components not defined in the present utility model all adopt conventional means in the art, such as lead billet roller conveyors, toggle bolts, temperature measuring probes, etc. Those skilled in the art can select their models and installation methods according to actual usage requirements, and clearly understand how to install and control them specifically, which will not be described in detail here.

[0012] The working principle of the present utility model is as follows: during use, according to the width of the lead billet, multiple temperature measuring probes are installed in the guide groove, and the temperature measuring probes are made to correspond to multiple equal segments in the width direction of the lead billet. Then, the movable clips on the temperature measuring probes are tightened to fix the temperature measuring probes in the guide groove. Next, the limit connecting member is loosened, the angle of the temperature measuring guide plate is adjusted, and after the temperature measuring probe is aligned with the upper surface of the lead billet, the limit connection is fixed to complete the adjustment of the angle of the temperature measuring probe. When the specifications of the lead billet change, the number of temperature measuring probes in the guide groove can be increased or decreased as needed, or the interval between the temperature measuring probes can be adjusted by loosening the movable clips and then tightening the movable clips to make the temperature measuring points more evenly distributed, so as to be suitable for uniformly monitoring the temperatures of lead billets of different specifications.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: the structure of the device is simple, and the distance and angle of the temperature measuring elements can be adjusted conveniently, which is suitable for uniformly monitoring the temperatures of lead billets of different widths.

[0018] Embodiment

[0019] As Figures 1-2As shown in the figure, this embodiment proposes a lead billet temperature detection mechanism, which includes a lead billet roller conveyor, a limit connecting piece, and a temperature measurement guiding plate 2 rotatably connected between the two side brackets 1 of the lead billet roller conveyor. The limit connecting piece can limit the inclination angle of the temperature measurement guiding plate on the two side brackets. A long strip-shaped guiding groove 3 is opened on the temperature measurement guiding plate. The length direction of the guiding groove is consistent with the width direction of the lead billets (not shown in the figure) on the lead billet roller conveyor, and the groove length of the guiding groove matches the maximum width of the lead billets that can be conveyed on the lead billet roller conveyor. Three temperature measurement probes 4 that can be slidably adjusted along the length direction of the guiding groove are arranged in the guiding groove, and the model of the temperature measurement probe is PT100.

[0020] Specifically, an annular fixed clip 5 is sleeved on the upper part of the temperature measurement probe, and an annular movable clip 6 is threadedly connected to the lower part of the temperature measurement probe. The outer diameters of the fixed clip and the movable clip are both larger than the groove width of the guiding groove, and the diameter of the temperature measurement probe is smaller than the groove width of the guiding groove. By loosening or tightening the movable clip, the distance between the temperature measurement probes can be conveniently adjusted, and the temperature measurement probes can be limited on the guiding groove.

[0021] More specifically, the limit connecting piece includes two corresponding sheep's head bolts 7 that slidably penetrate through the two side brackets. The two ends of the temperature measurement guiding plate are centered with screw holes (not shown in the figure) that are threadedly connected to the corresponding sheep's head bolts. By loosening the sheep's head bolts, the inclination angle of the temperature measurement guiding plate can be adjusted, and then the angle of the temperature measurement probes can be adjusted. After adjustment, by tightening the sheep's head bolts, the inclination angle of the temperature measurement guiding plate can be limited.

[0022] It should be noted that in this embodiment, the lead billet roller conveyor, the sheep's head bolts, and the temperature measurement probes are all prior arts and will not be described in detail here.

[0023] The working principle of the present utility model is as follows: When in use, according to the width of the lead billets, three temperature measurement probes are installed in the guiding groove, and the temperature measurement probes correspond to the center and both ends in the width direction of the lead billets. Then, the movable clips on the temperature measurement probes are tightened to fix the temperature measurement probes in the guiding groove. Next, the limit connecting piece is loosened, and the angle of the temperature measurement guiding plate is adjusted. After the temperature measurement probes are aligned with the upper surface of the lead billets, the limit connection is fixed to complete the adjustment of the angle of the temperature measurement probes. When the specifications of the lead billets change, the number of temperature measurement probes in the guiding groove can be increased or decreased as needed, or the interval between the temperature measurement probes can be adjusted by loosening the movable clips and then tightening the movable clips to make the temperature measurement points more evenly distributed, so as to be suitable for uniformly monitoring the temperatures of lead billets of different specifications.

[0024] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
