Description

Technical Field

[0001] The present invention relates to the field of paper bag production, in particular to a punching device for paper bag production. Background Art

[0002] During paper bag production, it is often necessary to punch holes in the bags to install drawstrings or other decorative parts. During punching, a punching method is usually used to generate shear force at specific locations on the bags to punch the holes. Considering that paper bags are soft and easy to punch, in order to improve the efficiency of paper bag punching, several paper bags are often stacked together for punching. On the one hand, this punching method can only punch several paper bags at a time. Too many stacked paper bags will lead to insufficient shear force, which will cause the edges of the holes punched in the paper bags to slightly bulge in a certain direction due to the shear force at the punching location. In addition, the burrs between the paper bags will hook together, causing the paper bags to stick together. Before the next production operation, the stuck paper bags need to be separated. The increased operation steps can also easily cause the paper bags to rupture at the punching location. Summary of the Invention

[0027] Combined with attachment Figures 1 to 8 A punching device for paper bag production includes a base plate 1, a second mounting plate 3 is provided at the left and right ends of the base plate 1, a first mounting plate 2 is provided at the front and back sides of the base plate 1, a distribution box 4 is provided in the middle of the base plate 1, and a third mounting plate 5 is provided at the left end of the distribution box 4.

[0028] The first mounting plates 2 are symmetrically fixed to the front and back of the middle part of the bottom plate 1, the first mounting plate 2 is fixed to the inner side of the first mounting plate 2, the inner end of the first electric telescopic rod 201 is fixed to the first push plate 202, and no less than forty push plates 203 are evenly fixed to the inner side of the first push plate 202. A first positioning hole 204 is provided on the push plate 203. After the push plate 203 is fully inserted into the plate slot 401, the first positioning hole 204 can be aligned with the second positioning hole 403, so that the punching tube 305 can be inserted into the first positioning hole 204 and the second positioning hole 403 at the same time to punch the paper bag.

[0029] A second mounting plate 3 is fixed to the left and right ends of the bottom plate 1 respectively, a second electric telescopic rod 301 is fixed to the inner middle part of the second mounting plate 3, a push plate 302 is fixed to the inner end of the second electric telescopic rod 301, and motors 303 are symmetrically installed on the front and back sides of the inner side of the push plate 302. The output end of the motor 303 is connected to the burr scraping shaft 304 through a coupling. The burr scraping shaft 304 has a spiral cross section. When the burr scraping shaft 304 rotates, the sharp part at the tail can cut and trim the burrs in the hole of the paper bag. A punching tube 305 is fixed to the inner end of the burr scraping shaft 304.

[0030] A distribution box 4 is fixed in the middle of the upper surface of the base plate 1, and no less than forty plate feeding grooves 401 are equidistantly provided on the front side of the distribution box 4, and no less than forty distribution plates 404 are equidistantly fixed on the rear side of the distribution box 4. A mounting hole 402 is provided in the middle of the front end of the left side of the distribution box 4, a second positioning hole 403 is provided on the front side of the distribution box 4, and a third positioning hole 405 is provided on the rear side of the distribution box 4 and the distribution plate 404.

[0031] A third mounting plate 5 is fixed to the left of the distribution box 4 on the upper surface of the bottom plate 1, a third electric telescopic rod 501 is fixed to the middle of the right side of the third mounting plate 5, a pressing plate 502 is fixed to the right end of the third electric telescopic rod 501, and a fourth positioning hole 503 is provided on the pressing plate 502. The fourth positioning hole 503 can be used for the punching tube 305 to pass through, so that the burr scraping shaft 304 contacts all the paper bags in the distribution box 4 and then rotates to remove burrs.

[0032] The front push plate 203 is slidably connected in the plate feeding groove 401 , and the rear push plate 203 is slidably connected between the material dividing plates 404 .

[0033] The width of the feed slot 401 is equal to the thickness of the dividing plate 404. The width of the feed slot 401 and the thickness of the dividing plate 404 are both designed to be equal to the width of a paper bag, so that the push plate 203 can push a paper bag between the dividing plates 404. The extended part of the dividing plate 404 passes through the feed slot 401, so that when the front push plate 203 moves backward, one of the two adjacent paper bags in the dividing box 4 can be pushed between the dividing plates 404. Using rigid push plates 203 and dividing plates 404 to separate the paper bags makes punching and shearing easier, and at the same time prevents the paper bags from sticking together during batch punching.

[0034] The burr scraping shaft 304 on the left is slidably connected in the third positioning hole 405 , and the burr scraping shaft 304 on the right is slidably connected in the second positioning hole 403 .

[0035] The third electric telescopic rod 501 is slidably connected in the mounting hole 402 , and the pressing plate 502 is slidably connected to the front half of the material distribution box 4 .

[0036] Wheels are installed under the first push plate 202 and the push plate 302 to make the push plate 302 and the first push plate 202 move more smoothly and reduce the torque on the first mounting plate 2 and the second mounting plate 3.

[0037] The punching device for paper bag production is described. When in use, the paper bags are stacked and placed in the front half of the inner part of the distribution box 4. The first electric telescopic rod 201 installed at the front end of the bottom plate 1 starts to extend and drives the pushing plate 203 to move backward through the first pushing plate 202, so that the pushing plate 203 is inserted into the plate feeding slot 401 and continues to move backward. The spacing between the pushing plates 203 is equal to the width of the paper bags. During the backward movement of the pushing plate 203 in the distribution box 4, every other paper bag stacked together in the distribution box 4 can be pushed backward to enter between the distribution plates 404. When the first positioning hole 204 moves to align with the second positioning hole 403, a paper bag is respectively embedded in the gap between the push plate 203 and the dividing plate 404. At this time, the two second electric telescopic rods 301 start to extend and drive the push plate 302, the motor 303 and the burr scraping shaft 304 to move toward the middle of the bottom plate 1, so that the burr scraping shaft 304 is inserted into the second positioning hole 403 and the third positioning hole 405 from the left and right sides respectively. The punching tube 305 can punch and cut holes on the paper bag embedded between the push plate 203 and the dividing plate 404 under the action of shear force, and the cut paper pieces can be stored in Inside the punching tube 305, after the burr scraping shaft 304 passes through the distribution box 4, the motor 303 starts to drive the burr scraping shaft 304 to rotate to scrape off the edge burrs on the inner side of the hole punched on the paper bag, and then the first electric telescopic rod 201 on the rear side extends, and the first electric telescopic rod 201 on the front side shortens synchronously, and the two sets of push plates 203 maintain a constant distance and move forward together to push the paper bag in the distribution plate 404 back into the inner front side of the distribution box 4. Since the paper bags in the push plate 203 and the distribution plate 404 are punched from the left and right directions respectively, the push plate 203 and the distribution plate 4 04, the edges of the holes on the opposite direction of the protrusions, when the paper bags in the dividing plate 404 are moved back to the front side of the dividing box 4 and merged with the paper bags on the front side, the edges of the holes of adjacent paper bags are protruded in opposite directions, so as to prevent the edges of the paper bags from sticking together, and then the third electric telescopic rod 501 is extended to drive the pressing plate 502 to move to the right in the dividing box 4 to squeeze and compress the paper bags with holes in the dividing box 4, and flatten the protrusions on the edges of the paper bag holes, and then the third electric telescopic rod 501 drives the pressing plate 502 to return to its original position, and the staff can take out the punched paper bags from the dividing box 4.
