Description

Technical Field

[0001] The invention relates to the technical field of plate grid processing, and in particular to a heating device on both sides of a plate grid. Background Art

[0002] The grid is one of the basic materials of lead-acid batteries. It accounts for about 25% of the total mass of the battery. Its main functions are: first, it supports the active material and acts as a carrier of the active material. Second, it conducts and collects current so that the current is evenly distributed on the active material. The grid, like a skeleton, can be used to support the active material to form an electrode. It can be seen that the grid occupies an important position and role in the entire production process of the battery. The above-mentioned grid is heavy, has poor corrosion resistance to sulfuric acid, has a short battery life, and lead pollution seriously damages the ecology. Therefore, the country is gradually phasing it out and developing a composite mesh grid, which is woven with carbon fiber coaxial composite zinc wire (i.e., a composite material formed by uniformly coating the surface of the carbon fiber core wire with zinc alloy). It is not only light in weight and meets environmental protection requirements, but also extends the service life of the battery. The composite mesh grid includes composite wires and hot melt wires. First, the composite wires are woven into a mesh structure, and then divided into several grid strips along the warp according to the set width. The edges of both sides of each grid strip are woven with hot melt wires to prevent the warp and weft of the composite mesh grid from loosening or detaching. The existing hot melt wires are generally of the same thickness, while the composite wires are of different thicknesses. After weaving, the hot melt wires need to be heated to melt them and lock the edges of both sides of each grid strip. Now, the hot melt wires are generally heated by setting a heating lamp on one side of the composite mesh grid, so that only the hot melt wire on one side can be heated, and the hot melt wire and the composite wire are woven together, so that the hot melt wires are distributed on both sides, which makes the hot melt effect poor and the composite mesh grid is prone to disconnection; at the same time, the existing hot melt wires are generally of the same thickness, while the composite wires are of different thicknesses, resulting in different thicknesses of the entire composite grid, and the distance between the heating lamp and the composite mesh grid remains unchanged, which will lead to excessive hot melt or poor hot melt. Summary of the invention

[0003] The present invention aims to provide heating devices on both sides of the grid, improve the utilization rate of heat by the hot melt line, and shorten the hot melt time; according to the weight of the composite mesh grid, the distance between the composite mesh grid and the heating lamp is adjusted to achieve a good hot melt effect.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: heating devices on both sides of the grid include a base, a first guide roller and a second guide roller, the first guide roller and the second guide roller are respectively connected to the two ends of the base for vertical rotation, a feeding table that can move up and down along one side of the base is provided at the front end of the base, heating lamps are respectively provided on both sides of the base located at the composite mesh grid, and an adjustment mechanism is provided between the heating lamps on both sides, the distance of which can be adjusted according to the weight of the composite mesh grid.

[0005] Beneficial effects:

[0006] 1. In the present invention, heating lamps are arranged on both sides, so that both sides of the hot melt line can be heated, so that the hot melting is more complete, and the loosening of the composite mesh grid can be avoided.

[0007] 2. The present invention provides an adjustment mechanism. Since the thickness of the hot melt wires of the composite mesh grid is the same, but the thickness of the composite wires is different, resulting in different thickness and weight of the composite mesh grid. In this way, the weight of the composite mesh grid can be used to adjust the distance between the heating lamps on both sides of the composite mesh grid, thereby adjusting the degree of heating of the hot melt wires by the heating lamps. Ultimately, the hot melt wires are heated evenly, the nodules formed by hot melting are relatively firm, and the heating lamps will not have much impact on the composite wires.

[0008] 3. In the present invention, the first guide roller and the second guide roller are arranged vertically, which is convenient for installing the heating lamps on both sides and for displacement of the heating lamps, thereby increasing the adjustment space and making installation or maintenance more convenient.

[0009] Preferably, a first fixing block is fixedly connected to one side of the base close to the feed table, the lower end surface of the feed table is connected to the first fixing block via a first spring, and the feed table is vertically slidably connected to the side wall of the base. Due to the different weights of the composite mesh grid, the feed table is connected to the first fixing block via the first spring, and the height of the feed table can change according to the weight of the composite mesh grid, so that it can be used as a weight sensing structure, which is convenient for cooperation with the adjustment mechanism.

[0010] Preferably, the adjusting mechanism includes a first connecting rod, the upper end of the first connecting rod is hinged to the lower end surface of the feeding table, the lower end of the first connecting rod is hinged with a horizontally arranged second connecting rod, the lower end surface of the second connecting rod is hinged with a tripod, the second connecting rod is hinged with a third connecting rod at one end away from the first connecting rod, and the upper end of the third connecting rod is hinged with a diamond mechanism, the diamond mechanism includes a pair of first movable rods hinged to each other and a pair of second movable rods hinged to each other, the first movable rod is hinged to the second movable rod, the hinge points of the pair of first movable rods are hinged to the lower end surface of the base, and the hinge points of the pair of second movable rods are hinged to the third connecting rod; an adjusting block is fixedly connected to the lower end surface of the heating lamp on each side, a first sliding groove is provided on the base, the adjusting block slides along the first sliding groove, the lower end of the adjusting block extends out of the first sliding groove, and the lower end surface of the adjusting block is an inclined surface, and a second sliding groove is provided on the lower end surface of the adjusting block, and a fourth connecting rod is vertically fixedly connected to each first movable rod, and the upper end of the fourth connecting rod is rotatably connected to a roller, and the roller slides along the second sliding groove.

[0011] By setting up an adjustment mechanism, it can be adjusted according to the weight of the composite mesh grid. When the weight of the composite mesh grid is heavier, the composite mesh grid causes the feed table to move downward, the first spring is compressed downward, the first connecting rod moves downward, the first connecting rod presses the second connecting rod downward, and the second connecting rod moves upward according to the lever principle. The other end of the second connecting rod moves upward, and the second connecting rod pushes the third connecting rod to move upward. The third connecting rod pushes the diamond mechanism upward, and the angle between a pair of first movable rods in the diamond mechanism becomes larger, and the fourth connecting rod connected to the first movable rod moves upward. The roller at the upper end of the fourth connecting rod has a certain displacement along the second slide groove, and the fourth connecting rod pushes the adjustment block to move along the first slide groove in the direction away from the composite mesh grid, and the distance between the heating lamps is successfully adjusted. Through the above structure, the distance between the heating lamps can be adjusted.

[0012] Preferably, the lower ends of the first guide roller and the second guide roller are both horizontally fixedly connected to a limit plate, and the cross-sectional shape of the limit plate is circular. By providing the limit plate, the composite mesh grid can be prevented from falling off the first guide roller and the second guide roller.

[0013] Preferably, guide plates are provided on both sides of the heating lamp to be inclined inwards, so as to prevent the heating lamp from repeatedly heating the composite wire near the hot melt line, thereby making the heat utilization rate of the heating lamp higher.

[0014] Preferably, a heat insulating layer is provided on the inner side of the guide plate, which can collect the heat of the heating lamp and concentrate it at the corresponding hot melt line, thereby improving the heat utilization rate of the heating lamp. BRIEF DESCRIPTION OF THE DRAWINGS
