When the first cam 1002 continues to rotate, the jacking shaft 172 moves downwards, and the battery barrel can exit from the positioning hole; the return spring 1005 always pulls the front end of the first oscillating bar 1003 to rotate upwards, so that the rear end of the first oscillating bar 1003 can move downwards, and the rear end of the first oscillating bar 1003 can be reset.

In the structure, because the height of the projection of the first cam 1002 is not very high, the swing amplitude of the first oscillating bar 1003 is not large, and the swing amplitude of the first lifting connecting rod 1001 is also small; when the rear end of the first swing link 1003 rotates upward, the first lifting link 1001 can provide upward thrust for the jacking shaft 172 to push the jacking shaft 172 to move upward.

Due to the structure, the second cam 2005 rotates, when the second guide wheel is located on the convex side of the second cam 2005 in the first annular groove 2006, the front end of the second oscillating bar 2004 is pushed to rotate upwards, the second lifting connecting rod 2002 is moved upwards, then the second punching head lifting rod 7 is moved upwards, and the second punching head 2 can be driven to move upwards. When the second cam 2005 continues to rotate, when the second guide wheel is located on the non-protruding side of the second cam 2005 in the first annular groove 2006, the front end of the second oscillating bar 2004 rotates downwards, so that the second lifting connecting rod 2002 moves downwards, then the second punching head lifting rod 7 moves downwards, and the second punching head 2 can be driven to move downwards to punch paper strips.

Due to the structure, the third cam 3002 rotates, when the third guide wheel is positioned on the convex side of the third cam 3002 in the second annular groove 3003, the rear end of the third swing rod 3006 is pushed to rotate upwards, so that the third lifting connecting rod 3001 moves upwards, then the lifting rod 8 of the pressing shaft moves upwards, and the pressing shaft 1 can be driven to move upwards. When the third cam 3002 continues to rotate and the third guide wheel is positioned on the non-convex side of the third cam 3002 in the second annular groove 3003, the rear end of the third swing rod 3006 rotates downwards, so that the third lifting connecting rod 3001 moves downwards, and then the lifting rod 8 of the pressing shaft moves downwards, so that the pressing shaft 1 can be driven to move downwards.

In the structure, because the height of the cam III 3002 is not very high, the swing amplitude of the swing rod III 3006 is not large, and the swing amplitude of the lifting connecting rod III 3001 is also small; when the rear ends of the swing rods 3006 rotate upwards, the lifting connecting rods 3001 can provide upwards thrust for the pressing shaft lifting rod 8 to push the pressing shaft lifting rod 8 to move upwards.

The first cam 1002, the second cam 2005 and the third cam 3002 are all arranged on the same camshaft 16, and the boss of the first cam 1002, the boss of the second cam 2005 and the boss of the third cam 3002 are offset from each other in the circumferential direction of the camshaft 16. The left end of the camshaft 16 is rotatably arranged at the lower end of the left connecting plate, and the right end of the camshaft is rotatably arranged at the lower end of the right connecting plate 15; the upper ends of the left connecting plate and the right connecting plate 15 are connected with the bottom of the supporting platform 14. One end of the cam mounting shaft is connected with a cam driving motor in a chain transmission or belt transmission mode.

Because the first cam 1002, the second cam 2005 and the third cam 3002 are arranged on the same cam shaft 16, one cam driving motor can drive the pressing shaft 1, the punching head 2 and the jacking shaft to work, meanwhile, the cam is an intermittent transmission mechanism, and the convex part of the first cam 1002, the convex part of the second cam 2005 and the convex part of the third cam 3002 are staggered in the circumferential direction of the cam shaft 16, so that the pressing shaft 1, the punching head 2 and the jacking shaft can be controlled to work cooperatively at certain time intervals. And can ensure that the time interval is fixed.

Further, the top of the positioning plate 5 is provided with a clamping sleeve 12 mounting groove; a clamping sleeve 12 is arranged in the clamping sleeve 12 mounting groove; the axis of the central hole 1200 of the clamping sleeve 12 is coincident with the axis of the positioning hole 501. The lower end of the pressing shaft 1 can firstly 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 base paper to enter the clamping sleeve 12, the clamping sleeve 12 can clamp the edge of the base paper on the pressing shaft 1, so that the base paper forms a paper bowl and is wrapped at the lower end of the pressing shaft 1. Then the pressing shaft 1 continues to move downwards to drive the paper bowl to move downwards, and the paper bowl is conveyed to the bottom of the battery barrel.

If the pressing shaft 1 directly presses the base paper, the friction exists between the inner wall of the battery tube and the base paper, so that the edge of the formed paper bowl is likely to be high at one side and low at the other side, and even the edge of the paper bowl is directly notched at the other side. If the paper bowl has a gap, materials such as manganese, zinc and the like can possibly run out of the paper bowl to be in contact with the inner wall of the battery tube. Resulting in poor production quality of the battery. Due to the existence of the clamping sleeve 12, the clamping sleeve 12 can enable the base paper to form a paper bowl on the pressing shaft 1 in advance and then be sent into the battery barrel, gaps can be prevented from appearing on the edge of the formed paper bowl, meanwhile, the clamping sleeve 12 can enable the edge of the paper bowl to be clamped on the pressing shaft 1, and wrinkles can be prevented from appearing on the edge of the paper bowl.

In the invention, the clamping sleeve 12 comprises an elastic ring 1205 and a plurality of clamping blocks 1201; the clamping block 1201 surrounds the positioning hole 501 for a circle and is spliced into an annular sleeve; the elastic ring 1205 is sleeved outside the annular sleeve; the clamping block 1201 can move in the radial direction of the annular sleeve in the mounting groove of the clamping sleeve 12, and the elastic ring 1205 is used for enabling the clamping block 1201 to move towards the center of the annular sleeve.

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 clamping block 1201 moves inward in the radial direction of the clamping sleeve 12 under the elastic force of the elastic ring 1205, so that the inner side of each clamping block 1201 clamps the pressing shaft 1, and further, the edge of the base paper can be clamped on the pressing shaft 1.

The clamping blocks 1201 are fan-shaped. So that the clamping sleeve 12 can be spliced into a complete cylinder shape, the central hole 1200 of the clamping sleeve is ensured to be a round hole, the edge of the base paper is further ensured to be clamped on the pressing shaft 1, and the fold at the edge of the paper bowl can be avoided.

The inner side surface of the clamping block 1201 comprises a guide surface 1204 which is obliquely arranged and a clamping surface 1203 which is vertically arranged from top to bottom; when the clamping blocks 1201 are spliced together, the inner side faces of the clamping blocks 1201 are spliced to form a central hole 1200, and the central hole 1200 comprises a guide hole spliced by the guide faces 1204 and a clamping hole spliced by the clamping faces 1203 from top to bottom; the diameter of the upper end of the guide hole is larger than that of the lower end of the guide hole.

Due to the existence of the guide surface 1204, the pressing shaft 1 can be conveniently inserted into the clamping sleeve 12, and the base paper can be conveniently formed into a paper bowl; the diameter of the upper end of the guide hole is larger than that of the pressing shaft 1; the clamping surface 1203 is then used to clamp the edge of the liner against the pressing shaft 1.

The upper end of the guide surface 1204 is inclined outwards, and the inclination angle alpha is 5 to 30 degrees.

A groove 1202 is formed in the outer side of the clamping block 1201; when the clamping blocks 1201 are spliced together, the groove 1202 forms an annular groove in which the spring ring 1205 is located.

Due to the existence of the annular groove, the elastic ring 1205 can be stably sleeved on the outer side of the clamping sleeve 12; the elastic ring 1205 is prevented from moving up or down during the working process, and further the elastic ring is prevented from separating from the clamping sleeve 12.

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

The number of the clamping blocks 1201 is at least 2. In the present invention, as shown in fig. 8, 4 fan-shaped clamping blocks 1201 are provided.

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

The radial movement distance of the clamping blocks can be limited due to the presence of the stop collar 502. Meanwhile, the clamping block 1201 can be ensured to be always positioned above the positioning hole 501, and the central hole 1200 of the clamping sleeve is ensured to be coaxial with the positioning hole 501.

At least one circle of 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 on the outer side of 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, and further the friction force between the bottom of the clamping block 1201 and the bottom of the mounting groove of the clamping sleeve 12 is reduced.

As shown in FIG. 10, the mounting groove of the clamping sleeve 12 is circular, and the bottom of the mounting groove of the clamping sleeve 12 is provided with a ring-shaped bottom groove 503.

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 enters the pressing shaft 1 and can blow down the bottom paper wrapped at the lower end of the pressing shaft 1, so that the bottom paper is prevented from being taken out when the pressing shaft 1 moves upwards and exits from the battery barrel. Meanwhile, the base paper is more favorably attached in the battery cylinder.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
