For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figures 1 to 9 As shown, the present invention discloses a battery tube bottom paper punching and cutting mechanism, which comprises a positioning plate 5, a punching template 4, a bottom paper pressing plate 3, a punching head 2 and a pressing shaft 1;

[0043] The positioning plate 5 is provided with a positioning hole 501 which vertically penetrates the tank positioning plate;

[0044] The punching template 4 is provided with a punching hole 401 which vertically penetrates the punching template 4;

[0045] The bottom paper pressing plate 3 is provided with a knife feed hole 301 which vertically penetrates the bottom paper pressing plate 3;

[0046] The lower end of the punching head 2 is cylindrical, and the punching head 2 can move up and down in the vertical direction;

[0047] The pressing shaft 1 passes through the punching head 2 and can move up and down in the punching head 2;

[0048] The punching template 4 is arranged on the positioning plate 5, the bottom paper pressing plate 3 is arranged on the punching template 4, the axes of the positioning hole 501, the punching hole 401 and the feed hole 301 coincide with each other; a paper feed channel 6 is reserved between the bottom paper pressing plate 3 and the punching template 4;

[0049] The punching head 2 is located above the bottom paper pressing plate 3, and the diameters of the feed hole 301 and the punching hole 401 match the diameter of the lower end of the punching head, so that the lower end of the punching head 2 can be inserted into the feed hole 301 and the punching hole 401; the lower end of the pressing shaft 1 can pass through the feed hole 301, the punching hole 401 and the positioning hole 501.

[0050] Due to the above structure, when the battery barrel bottom paper punching and barreling mechanism of the present invention is used, the paper strip is first placed in the paper feed channel 6, so that the paper strip is sandwiched between the bottom paper pressing plate 3 and the punching template 4, and the upper end of the battery barrel opening is inserted into the positioning hole 501; then the punching head 2 moves downward, first penetrates the feed hole 301 and then inserts into the punching hole 401, so that a part of the paper strip can be punched into a circular bottom paper; then the lower end of the pressing shaft 1 moves downward again, passes through the feed hole 301, the punching hole 401 and the positioning hole 501 to push the circular bottom paper into the battery barrel, and the bottom paper barreling operation is completed. The battery barrel bottom paper punching and barreling mechanism of the present invention completes the bottom paper cutting and bottom paper barreling operations at one station, which can effectively improve the battery production efficiency. At the same time, the positioning plate 5 can limit the horizontal movement of the battery barrel; ensure that the axis of the battery barrel coincides with the axis of the punching hole 401; and then facilitate the pressing shaft 1 to push the bottom paper into the battery barrel. The diameter of the positioning hole 501 matches the diameter of the battery barrel.

[0051] Furthermore, a clamping sleeve installation groove 504 is provided on the top of the positioning plate 5; a clamping sleeve 12 is provided in the clamping sleeve installation groove 504; the axis of the center hole 1200 of the clamping sleeve 12 coincides with the axis of the positioning hole 501. The lower end of the pressing shaft 1 can first pass through the center hole 1200 of the clamping sleeve and then through the positioning hole 501.

[0052] When the lower end of the pressing shaft 1 pushes the bottom paper into the clamping sleeve 12, the clamping sleeve 12 can clamp the edge of the bottom paper on the pressing shaft 1, so that the bottom paper forms a paper bowl and wraps around the lower end of the pressing shaft 1. Then the pressing shaft 1 continues to move downward, driving the paper bowl to move downward and sending the paper bowl to the bottom of the battery tube.

[0053] If the pressing shaft 1 directly presses the bottom paper, due to the friction between the inner wall of the battery tube and the bottom paper, the edge of the formed paper bowl may be high on one side and low on the other side, or even a gap may appear on one side of the edge 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 contact the inner wall of the battery tube, resulting in poor battery production quality. Due to the presence 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 feed it into the battery tube, which can avoid gaps on the edge of the formed paper bowl. At the same time, the clamping sleeve 12 can clamp the edge of the paper bowl on the pressing shaft 1, which can avoid wrinkles on the edge of the paper bowl.

[0054] In the present invention, if Figures 6 to 9As shown, the clamping sleeve 12 includes an elastic ring 1205 and a plurality of clamping blocks 1201; the clamping blocks 1201 surround the positioning hole 501 and are spliced ​​into an annular sleeve; the elastic ring 1205 is sleeved on the outside of the annular sleeve; the clamping block 1201 can move in the clamping sleeve mounting groove 504 along the radial direction of the annular sleeve, and the elastic ring 1205 is used to move the clamping block 1201 toward the center of the annular sleeve.

[0055] Due to the above structure, when the pressing shaft 1 passes through the center hole 1200 of the annular sleeve, it can push each clamping block 1201 to move outward in the radial direction of the clamping sleeve 12. Due to the presence of the elastic ring 1205, each clamping block 1201 moves inward 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, thereby enabling the edge of the bottom paper to be clamped on the pressing shaft 1.

[0056] like Figure 7 As shown, the clamping block 1201 is fan-shaped, so that the clamping sleeve 12 can be spliced ​​into a complete cylindrical shape, ensuring that the center hole 1200 of the clamping sleeve is a round hole, thereby ensuring that the edge of the bottom paper can be clamped on the pressing shaft 1, and wrinkles can be avoided on the edge of the paper bowl.

[0057] The inner side surface of the clamping block 1201 includes an inclined guide surface 1204 and a vertically arranged clamping surface 1203 from top to bottom; when the clamping blocks 1201 are spliced ​​together, the inner side surface of the clamping block 1201 is spliced ​​into a center hole 1200, and the center 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.

[0058] Due to the existence of the guide surface 1204, the pressing shaft 1 can be easily inserted into the clamping sleeve 12, and the bottom paper can also be easily formed into a paper bowl; the diameter of the upper end of the guide hole is larger than the diameter of the pressing shaft 1; the clamping surface 1203 is used to clamp the edge of the bottom paper on the pressing shaft 1.

[0059] The upper end of the guide surface 1204 is inclined outward, and the inclination angle α is 5-30°.

[0060] A groove 1202 is formed on the outer side 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.

[0061] Due to the presence of the annular groove, it is possible to ensure that the elastic ring 1205 is stably sleeved on the outside of the clamping sleeve 12 , thereby preventing the elastic ring 1205 from moving up or down during operation and then separating from the clamping sleeve 12 .

[0062] 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 to provide elastic force so that the clamping block 1201 always has a tendency to move inward in the radial direction so as to clamp the pressing shaft 1.

[0063] There are at least two clamping blocks 1201. Figure 7 As shown, in the present invention, four fan-shaped clamping blocks 1201 are provided.

[0064] like Figure 8 As shown, a limiting groove 1206 is provided at the bottom of the clamping block 1201; when the clamping blocks 1201 are spliced ​​together, the limiting groove 1206 forms an annular limiting groove 1206; a limiting ring 502 is provided at the bottom of the clamping sleeve mounting groove 504, and the limiting ring 502 is located 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.

[0065] The presence of the limiting ring 502 can limit the radial movement distance of the clamping block, and at the same time, can ensure that the clamping block 1201 is always above the positioning hole 501, and ensure that the center hole 1200 of the clamping sleeve is coaxial with the positioning hole 501.

[0066] like Fig. 9 As shown, at least one annular bottom groove 503 is formed at the bottom of the clamping sleeve installation groove 504 . The annular bottom groove 503 is located outside the positioning hole 501 and is concentric with the positioning hole 501 .

[0067] Due to the presence of the annular bottom groove 503 , the contact area between the bottom of the clamping block 1201 and the bottom of the clamping sleeve installation groove 504 can be reduced, thereby reducing the friction between the bottom of the clamping block 1201 and the bottom of the clamping sleeve installation groove 504 .

[0068] like Fig. 9 As shown, the clamping sleeve installation groove 504 is circular, and a circle of annular bottom groove 503 is arranged at the bottom of the clamping sleeve installation groove 504 .

[0069] Furthermore, the punching head 2 is connected to a punching head lifting mechanism, and the punching head lifting mechanism is used to drive the punching head 2 to move up and down; the pressing shaft 1 is connected to a pressing shaft lifting mechanism, and the pressing shaft lifting mechanism is used to drive the pressing shaft 1 to move up and down.

[0070] like Figure 2 , 3As shown, the battery tube bottom paper punching and cutting mechanism includes a body 13; a positioning plate 5, a punching template 4, and a bottom paper pressing plate 3 are all located on the front of the body 13; the positioning plate 5 is fixedly arranged on the body 13; the punching template 4 is arranged on the top of the positioning plate 5 by bolts, and the bottom paper pressing plate 3 is arranged on the top of the punching template 4 by bolts; the punching head 2 is arranged on the body 13 by a punching head lifting mechanism; and the pressing shaft 1 is arranged on the body 13 by a pressing shaft lifting mechanism.

[0071] Furthermore, the punching head lifting mechanism includes a punching head mounting shaft 11, a punching head mounting plate 10 and a punching head lifting rod 7; the punching head lifting rod 7 vertically penetrates the machine body 13, and the lower end of the punching head lifting rod 7 is connected to the punching head lifting rod driving mechanism, and the punching head lifting rod driving mechanism is used to drive the punching head lifting rod 7 to move up and down in the machine body 13; the upper end of the punching head lifting rod 7 is connected to the punching head mounting plate 10; the upper end of the punching head mounting shaft 11 is connected to the punching head mounting plate 10, and the lower end of the punching head mounting shaft 11 is connected to the punching head 2; the punching head mounting shaft 11 is a hollow shaft, so that the lower end of the pressing shaft 1 can pass through the punching head mounting shaft 11.

[0072] The pressing shaft lifting mechanism includes a pressing shaft mounting plate 9 and a pressing shaft lifting rod 8; the pressing shaft lifting rod 8 vertically penetrates the machine body 13 and the punching head mounting plate 10, and the lower end of the pressing shaft lifting rod 8 is connected to the pressing shaft lifting rod driving mechanism, and the pressing shaft lifting rod driving mechanism is used to drive the pressing shaft lifting rod 8 to move up and down in the machine body 13 and the punching head mounting plate 10; the upper end of the pressing shaft lifting rod 8 is connected to the pressing shaft mounting plate 9; the upper end of the pressing shaft 1 is connected to the pressing shaft mounting plate 9, and the lower end of the pressing shaft 1 penetrates the punching head mounting shaft 11 and the punching head 2, and can move up and down in the punching head mounting shaft 11 and the punching head.

[0073] The punching head lifting rod driving mechanism and the pressing shaft lifting rod driving mechanism can be cylinders. The following structures can also be adopted.

[0074] The battery tube bottom paper punching and cutting mechanism of the present invention should be arranged on the supporting platform 14 when in use. Figure 3 As shown, the machine body is fixedly arranged on the supporting platform 14, and the punching head lifting rod 7 and the pressing shaft lifting rod 8 are extended to the bottom of the supporting platform 14 and connected with the punching head lifting rod driving mechanism and the pressing shaft lifting rod driving mechanism under the supporting platform 14.

[0075] In the present invention, the punching head lifting rod driving mechanism includes a swing rod 2004, a lifting connecting rod 2002, a cam 2005 and a guide wheel 1; the rear end of the swing rod 2004 is rotatably set on a rotating shaft 2003 and can rotate in the vertical direction; the rotating shaft 2003 is fixedly set at the lower end of a connecting plate 2001, and the upper end of the connecting plate 2001 is connected to the bottom of the support platform 14; the middle part of the swing rod 2004 is movably connected to the lower end of the lifting connecting rod 2002, and the upper end of the lifting connecting rod 2002 is movably connected to the lower end of the punching head lifting rod 7; specifically, the lifting connecting rod 2002 The lower end of 2002 is hinged to the middle part of the rocker arm 2004 through a pin shaft, and the upper end of the lifting connecting rod 2002 is connected to the lower end of the punching head lifting rod 7 through a ball joint; the guide wheel is rotatably arranged on the side of the rocker arm 2004, located at the front end of the rocker arm 2004; an annular groove 2006 is opened on the side of the cam 2005, and the annular groove 2006 is arranged along the edge of the cam 2005, so that the shape of the annular groove 2006 matches the outer contour of the cam 2005; the guide wheel is placed in the annular groove 2006 and can move in the annular groove 2006.

[0076] Due to the above structure, when the cam 2005 rotates, when the guide wheel 1 is located on the raised side of the cam 2005 in the annular groove 2006, the front end of the swing rod 1 2004 is pushed to rotate upward, thereby causing the lifting link 1 2002 to move upward, and then causing the punching head lifting rod 7 to move upward, thereby driving the punching head 2 to move upward. When the cam 2005 continues to rotate, when the guide wheel 1 is located on the non-raised side of the cam 2005 in the annular groove 2006, the front end of the swing rod 1 2004 rotates downward, thereby causing the lifting link 1 2002 to move downward, and then causing the punching head lifting rod 7 to move downward, thereby driving the punching head 2 to move downward to punch and cut paper strips.

[0077] In the above structure, since the protrusion height of the cam 2005 is not very high, the swing amplitude of the rocker arm 2004 is not large, and the swing amplitude of the lifting link 2002 is also small; when the front end of the rocker arm 2004 rotates upward, the lifting link 2002 can provide an upward thrust for the punching head lifting rod 7, pushing the punching head lifting rod 7 to move upward.

[0078] In the present invention, the pressing shaft lifting rod driving mechanism includes a rocker rod 3006, a lifting connecting rod 3001, a cam 3002 and a guide wheel 2; the front end of the rocker rod 3006 is rotatably set on the rotating shaft 3004 and can rotate in the vertical direction; the rotating shaft 3004 is fixedly set at the lower end of the connecting plate 3005, and the upper end of the connecting plate 3005 is connected to the bottom of the supporting platform 14; the rear end of the rocker rod 3006 is movably connected to the lower end of the lifting connecting rod 3001, and the upper end of the lifting connecting rod 3001 is movably connected to the lower end of the pressing shaft lifting rod 8; specifically, the lifting connecting rod The lower end of the second 3001 is hinged to the rear end of the second rocker arm 3006 through a pin shaft, and the upper end of the lifting connecting rod 3001 is connected to the lower end of the pressing shaft lifting rod 8 through a ball joint; the guide wheel 2 is rotatably set on the side of the second rocker arm 3006, located in the middle of the second rocker arm 3006; the side of the second cam 3002 is provided with an annular groove 3003, and the annular groove 3003 is set along the edge of the second cam 3002; the shape of the annular groove 3003 matches the outer contour of the second cam 3002; the guide wheel 2 is placed in the annular groove 3003 and can move in the annular groove 3003.

[0079] Due to the above structure, the second cam 3002 rotates, and when the second guide wheel is located on the convex side of the second cam 3002 in the second annular groove 3003, the rear end of the second swing rod 3006 is pushed to rotate upward, thereby causing the second lifting link 3001 to move upward, and then causing the pressing shaft lifting rod 8 to move upward, thereby driving the pressing shaft 1 to move upward. When the second cam 3002 continues to rotate, when the second guide wheel is located on the non-convex side of the second cam 3002 in the second annular groove 3003, the rear end of the second swing rod 3006 rotates downward, thereby causing the second lifting link 3001 to move downward, and then causing the pressing shaft lifting rod 8 to move downward, thereby driving the pressing shaft 1 to move downward.

[0080] In the above structure, since the protrusion height of the cam 3002 is not very high, the swing amplitude of the rocker arm 3006 is not large, and the swing amplitude of the lifting link 3001 is also small; when the rear end of the rocker arm 3006 rotates upward, the lifting link 3001 can provide an upward thrust for the pressing shaft lifting rod 8, pushing the pressing shaft lifting rod 8 to move upward.

[0081] The cam 1 2005 and the cam 2 3002 are both arranged on the same camshaft 16, and the protrusion of the cam 1 2005 and the protrusion of the cam 2 3002 are staggered 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 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 to the bottom of the support platform 14. One end of the cam mounting shaft is connected to the cam driving motor by chain drive or belt drive.

[0082] Since cam one 2005 and cam two 3002 are arranged on the same camshaft 16, a cam drive motor can drive the pressing shaft 1 and the punching head 2 to work. At the same time, the cam is an intermittent transmission mechanism. The raised portion of cam one 2005 and the raised portion of cam two 3002 are staggered with each other in the circumferential direction of the camshaft 16, which can control the punching head 2 and the pressing shaft 1 to work together at a certain time interval and ensure that the time interval is fixed.

[0083] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
