Description

Technical Field

[0001] The utility model relates to the technical field of pole plate production, in particular to a paste blocking plate for pole plate continuous coating. Background Art

[0002] At present, in the conventional battery plate production process, the existing technology adopts a continuous rolling and coating integrated production line, and adopts a coating machine for coating. The coating machine usually includes a main transmission device, an electronic control device, a conveying device and a paste bucket part. A conveying device is provided under the paste bucket part. The grid is brought to the bottom of the paste bucket through the conveying device and coated by the lower paste roller in the paste bucket. Due to the different specifications and models of batteries, the grids also have various models.

[0003] In the production of lead-acid battery coating, the following problems were found during the coating process: when the coating machine was coating the grid with lead paste, there was a lot of excess paste on the plate ears, and the slicing cutter was seriously sticky with paste; when the paste-blocking plate was cut, the thickness of the coated plate was uneven and the flatness was not good, so it needed to be trimmed, wasting manpower and material resources.

[0004] Patent document CN212033140U discloses a novel continuous coating paste shield device. The paste shield body is equipped with multiple discharge ports, located on either side of the discharge ports. The body is also equipped with a beading slot. A beading holder is detachably connected to the body. A beading engagement portion is formed between the beading slot and the holder. The beading fits entirely within the beading slot, with one end of the beading engaging the beading engagement portion. The PP beading blocks lead paste from overflowing and preventing leakage. However, during use, the beading comes into sliding contact with the grid, making it susceptible to wear. Once worn, it loses its ability to block lead paste.

[0005] The patent document with publication number CN217522041U discloses an improved continuous coating new paste shield device. When it is first installed and not used, the upper surface of the pressure strip is separated from the bottom surface of the installation groove. At this time, under the action of the spring, the upper surface of the flat head screw head contacts the upper surface of the countersunk through hole. When used for the first time, when the main body of the paste shield contacts the electrode plate, the lower surface of the pressure strip contacts the electrode ear and can be squeezed into the installation groove. The upper surface of the pressure strip fits with the bottom surface of the installation groove. During operation, the pressure strip is always in contact with the electrode ear of the grid. After the pressure strip is worn, the pressure strip can still squeeze the electrode ear of the grid under the elastic force of the spring, and can continuously block the lead paste, which can reduce the frequency of pressure strip replacement. However, if the size of the grid changes, the paste shield needs to be replaced as a whole, and cannot be applied to the production of electrodes of different sizes. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a paste blocking plate for continuous coating of pole plates which can be applicable to the production of pole plates of different sizes and can reduce the frequency of replacing bead strips.

[0007] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0008] A paste baffle for continuous coating of electrode plates comprises a paste baffle body, a material hole is opened on the paste baffle body, side wings are processed at both ends of the paste baffle body, the lower ends of the side wings are flush with the lower end of the paste baffle body, an adjustment plate is slidingly sleeved on the side wings, the adjustment plate and the paste baffle body are connected by screws, and the distance between the adjustment plate and the paste baffle body can be adjusted by rotating the screws, a rubber strip is fixed to the side of the adjustment plate part below the side wings facing the middle direction of the paste baffle body, the upper end of the rubber strip is in contact with the lower end of the side wings, a top strip is fixed to the lower end of the rubber strip, and a pressure strip is fixed to the lower end of the top strip.

[0009] Specifically, the screw is rotatably connected to the adjustment plate, and the screw is threadedly connected to the plaster plate body.

[0010] Specifically, a guide slope is processed on the lower side of the end of the paste baffle body facing the grid material supply.

[0011] Specifically, the side wings and the regulating plate are inclined upwards toward the end of the grid from which the material is fed.

[0012] Specifically, the length directions of the rubber strips, top strips and pressure strips are parallel to the movement direction of the grid.

[0013] Specifically, a guiding slope is processed on the lower side of one end of the pressure strip facing the grid material.

[0014] Specifically, the pressure strip is made of PP material.

[0015] Specifically, a material collecting groove communicated with the material hole is provided at the upper end of the paste baffle body.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. After the grid of the plate moves to the bottom of the paste blocking plate body, the lower end of the pressure strip contacts the pole ear of the plate grid, the rubber strip is squeezed, and the lead paste discharged from the material hole is blocked by the pressure strip, top strip and rubber strip, thereby preventing the lead paste from adhering to the pole ear of the plate grid.

[0018] 2. The utility model can adjust the position of the rubber strip, top strip and pressure strip by setting an adjustment plate, and can change the distance between the rubber strip, top strip and pressure strip and the paste plate body. When the size of the plate grid changes, the position of the rubber strip, top strip and pressure strip can be adjusted to ensure that the pressure strip is in contact with the pole ear when coating the plate, and can be suitable for the production of plates of different sizes.

[0019] 3. Because the rubber strip is elastic, when the strip is worn, the strip will always squeeze the plate grid ear under the elastic force of the rubber strip, which can reduce the replacement frequency of the strip, increase the service life of the strip, and improve the efficiency of plate continuous coating.

[0026] 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 the embodiments.

[0027] Example 1: Reference Figure 1-Figure 5 As shown, a paste shield for continuous coating of electrode plates comprises a paste shield body 1 , on which a material hole 3 is opened.

[0028] The lower side of the plaster baffle body 1 facing the grid material inlet end is processed with a guide slope.

[0029] Both ends of the plaster board body 1 are processed with side wings 4, the lower ends of the side wings 4 are flush with the lower end of the plaster board body 1, and an adjustment plate 5 is provided on the sliding sleeve of the side wings 4. The adjustment plate 5 is connected to the plaster board body 1 by a screw 6. Rotating the screw 6 can adjust the distance between the adjustment plate 5 and the plaster board body 1. Specifically, the screw 6 is rotatably connected to the adjustment plate 5, and the screw 6 is threadedly connected to the plaster board body 1.

[0030] The side wings 4 and the regulating plate 5 are inclined upwards toward one end of the grid material feed.

[0031] A rubber strip 7 is fixed to the side of the adjustment plate 5 below the side wing 4, facing the middle of the plaster shield body 1. The upper end of the rubber strip 7 contacts the lower end of the side wing 4. A top strip 8 is fixed to the lower end of the rubber strip 7, and a pressure strip 9 is fixed to the lower end of the top strip 8. The length direction of the rubber strip 7, top strip 8, and pressure strip 9 is parallel to the movement direction of the grid.

[0032] The lower side of the bead 9 facing the grid material is machined with a guide slope 10. The bead 9 is made of PP material. The guide slope 10 facilitates the movement of the grid tab to the bottom of the bead 9, preventing the grid from getting stuck.

[0033] During operation, the plasterboard body 1 is first placed across the grid conveyor belt and secured by a frame. Above the plasterboard body 1 is a lead paste hopper, and below it is the grid conveyor belt. The lower end of the lead paste hopper is fixed above the plasterboard body 1. Lead paste discharged from the lead paste hopper is discharged through the material hole 3 and then applied to the grid conveyor belt.

[0034] After the grid of the electrode plate moves to the bottom of the paste blocking plate body 1, the lower end of the pressure strip 9 contacts the upper end of the pole ear of the electrode plate grid, the rubber strip 7 is squeezed, and the lead paste discharged from the material hole 3 is blocked by the pressure strip 9, the top strip 8 and the rubber strip 7, thereby preventing the lead paste from adhering to the pole ear of the electrode plate grid.

[0035] By setting the adjustment plate 5, the positions of the rubber strip 7, the top strip 8 and the pressure strip 9 can be adjusted, and the distance between the rubber strip 7, the top strip 8 and the pressure strip 9 and the paste baffle body 1 can be changed. When the size of the plate grid changes, the position of the adjustment plate 5, the rubber strip 7, the top strip 8 and the pressure strip 9 can be adjusted by rotating the screw 6, so that the lower end of the pressure strip 9 can be effectively in contact with the upper end of the pole ear when coating the plate, which can be suitable for continuous coating production of plates of different sizes.

[0036] Since the rubber strip 7 is elastic, when the bead 9 is worn, the bead 9 will always squeeze the plate grid ear under the elastic force of the rubber strip 7, which can reduce the replacement frequency of the bead 9, increase the service life of the bead 9, and improve the work efficiency of the continuous coating of the plate.

[0037] Example 2: Based on Example 1, refer to Figure 1 As shown, the upper end of the paste shield body 1 is provided with a collection trough 2 connected to a material hole 3. Lead paste drops from the lead paste hopper and continuously falls into the collection trough 2. The lead paste first accumulates in the collection trough 2 and then continuously discharges through the material hole 3, ensuring uniform material discharge and consistent thickness of the coated plates.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
