Further, the top of the positioning plate 5 is provided with a clamping sleeve 12 mounting groove; the clamping sleeve 12 is provided with a clamping sleeve 12 in the mounting groove; The axes coincide. The lower end of the pressing shaft 1 can first pass through the central hole 1200 of the clamping sleeve and then pass through the positioning hole 501 .

When the lower end of the pressing shaft 1 pushes the backing paper into the clamping sleeve 12, the clamping sleeve 12 can clamp the edge of the backing paper on the pressing shaft 1, so that the backing paper forms a paper bowl and is wrapped around the lower end of the pressing shaft 1. Then press shaft 1 to continue downward, driving the paper bowl to move down, and send the paper bowl to the bottom of the battery cylinder.

If the pressing shaft 1 directly presses the bottom paper, due to the friction between the inner wall of the battery can and the bottom paper, the edge of the formed paper bowl may be high on one side and low on the other, or even a gap may appear directly on one side of the paper bowl. If there is a gap in the paper bowl, materials such as manganese and zinc may run out of the paper bowl and come into contact with the inner wall of the battery cartridge. Resulting in poor battery production quality. And because of the existence of the clamping sleeve 12, the clamping sleeve 12 can make the bottom paper form a paper bowl on the pressing shaft 1 in advance, and then send it into the battery cartridge, which can avoid gaps in the edge of the formed paper bowl, and the clamping sleeve 12 can simultaneously The edge of the paper bowl is clamped on the pressing shaft 1 to avoid wrinkles on the edge of the paper bowl.

Due to the above structure, when the pressing shaft 1 passes through the central hole 1200 of the annular sleeve, each clamping block 1201 can be pushed to move outward in the radial direction of the clamping sleeve 12, and due to the existence of the elastic ring 1205, each The clamping block 1201 moves inwardly in the radial direction of the clamping sleeve 12 under the action of the elastic force of the elastic ring 1205, so that the inner side of each clamping block 1201 clamps the pressing shaft 1, and then the edge of the backing paper can be clamped on the Press on axis 1.

The clamping block 1201 is fan-shaped. In order to make the clamping sleeve 12 spliced into a complete cylindrical shape, ensure that the central hole 1200 of the clamping sleeve is a round hole, and then ensure that the edge of the backing paper can be clamped on the pressing shaft 1, and can avoid wrinkles on the edge of the paper bowl .

The inner surface of the clamping block 1201 includes an obliquely arranged guide surface 1204 and a vertically arranged clamping surface 1203 from top to bottom; The hole 1200, the central hole 1200 includes a guide hole spliced by the guide surface 1204 and a clamping hole spliced by the clamping surface 1203 from top to bottom; the diameter of the upper end of the guide hole is larger than the diameter of the lower end.

Due to the existence of the guide surface 1204, it is convenient to insert the pressing shaft 1 into the clamping sleeve 12, and it is also convenient for the bottom paper to form a paper bowl; the diameter of the upper end of the guide hole is larger than the diameter of the pressing shaft 1; The paper edge is clamped on the pressing shaft 1.

The upper end of the guide surface 1204 is inclined outward, and the inclination angle α is 5-30°.

A groove 1202 is formed on the outside of the clamping block 1201; when the clamping blocks 1201 are spliced together, the groove 1202 forms an annular groove, and the elastic ring 1205 is located in the annular groove.

Due to the existence of the annular groove, it is possible to ensure that the elastic ring 1205 is sleeved on the outside of the clamping sleeve 12 stably; and it is prevented that the elastic ring 1205 moves up or down during the working process, thereby detaching from the clamping sleeve 12 .

In the present invention, the elastic ring 1205 is a rubber ring or a spring ring. The elastic ring 1205 is always in a stretched state, so as to provide elastic force, so that the clamping block 1201 always has a tendency to move inward in the radial direction, so as to be able to clamp the pressing shaft 1 .

There are at least two clamping blocks 1201 . In the present invention, as shown in FIG. 8 , four fan-shaped clamping blocks 1201 are provided.

The bottom of the clamping block 1201 is provided with a limiting groove 1206; when the clamping blocks 1201 are spliced together, the limiting groove 1206 forms an annular limiting groove 1206; the bottom of the mounting groove of the clamping sleeve 12 is provided with a limiting ring 502, the limiting ring 502 is located at the top of the positioning hole 501, concentric with the positioning hole 501; the limiting ring 502 is located in the annular limiting groove 1206, and the width of the annular limiting groove 1206 in the radial direction is greater than the limit The width of the bit ring 502 in the radial direction.

Due to the existence of the limiting ring 502, the radial movement distance of the clamping block can be limited. At the same time, it can be ensured that the clamping block 1201 is always above the positioning hole 501 , and that the central hole 1200 of the clamping sleeve is coaxial with the positioning hole 501 .

At least one annular bottom groove 503 is formed at the bottom of the mounting groove 7 of the clamping sleeve 12 , and the annular bottom groove 503 is located outside the positioning hole 501 and is concentric with the positioning hole 501 .

Due to the existence of the annular bottom groove 503 , the contact area between the bottom of the clamping block 1201 and the bottom of the mounting groove of the clamping sleeve 12 can be reduced, thereby reducing the friction force between the bottom of the clamping block 1201 and the bottom of the mounting groove of the clamping sleeve 12 .

As shown in FIG. 10 , the mounting groove of the clamping sleeve 12 is circular, and an annular bottom groove 503 is provided at the bottom of the mounting groove of the clamping sleeve 12 .

Further, the pressing shaft 1 is a hollow shaft, and an air source is connected to the upper end of the pressing shaft 1 .

Due to the existence of the gas source, the gas entering the pressing shaft 1 can blow off the backing paper wrapped in the lower end of the pressing shaft 1, so as to prevent the backing paper from being taken out when the pressing shaft 1 moves up and exits the battery barrel. At the same time, it is also more conducive to the bonding of the bottom paper in the battery case.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or perform equivalent replacements for some of the technical features. Within the spirit and principles of the present invention, any modifications, equivalent replacements, improvements, etc., shall be included in the protection scope of the present invention.
