Description

Technical Field

[0001] This invention relates to the field of corrugated paper processing equipment technology, specifically a corrugated paper partial repair device for printing and packaging. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into single-wall corrugated paperboard and double-wall corrugated paperboard. During the production process, due to factors such as insufficient glue bonding time, delamination of corrugated paperboard often occurs. Since the edges and corners of corrugated paperboard are the outermost layer of glue bonding, delamination of the edges and corners of corrugated paperboard is very common.

[0003] Existing methods for repairing the edges and corners of corrugated paper typically involve manually lifting the corrugated paper at the point where the glue has come off and then applying glue using a glue gun. While this method effectively repairs the corrugated paper, the un-glueed parts tend to move under the pull when the paper is manually lifted, thus affecting the efficiency of the glue repair process. To further improve the efficiency of glue repair for the edges and corners of corrugated paper, we propose a localized repair device for corrugated paper used in printing and packaging. Summary of the Invention

The extrusion assembly includes: A lifting sleeve 204 is vertically mounted at the other end of the top of the base 1 and is slidably connected to the base 1. A motor 208 is installed at the bottom end of the lifting sleeve 204. The motor 208 is located inside the base 1. A drive shaft 2012 is fixedly connected to the output end of the motor 208. A switching plate 203 is fixedly connected to the top end of the drive shaft 2012. The switching plate 203 is located on the upper surface of the lifting sleeve 204 and is L-shaped. A lower pressure plate 201 is fixedly connected to one side of the bottom end of the switching plate 203. A movable sleeve plate 202 is integrally formed on one side of the bottom end of the switching plate 203. An airbag 209 is provided inside the base 1. 209 is located at one end of the motor 208 near the connecting seat 5. The top of the airbag 209 is fixedly connected to a lifting shaft 205 that is slidably connected to the base 1. The top of the lifting shaft 205 is integrally formed with a lifting block 2013. The outer walls of the upper and lower ends of the lifting block 2013 are symmetrical frustum shapes. The movable sleeve plate 202 is provided with an arc-shaped sleeve groove for fitting the lifting shaft 205 and the lifting block 2013. The bottom end of the airbag 209 is formed with a second air supply pipe that extends to the outside of one side of the base 1. The inner cavity of the second air supply pipe is interconnected with the inner cavity of the airbag 209. The airbag 209 is connected to the air pump through the second air supply pipe. The bending components include: A lifting plate 2010 is formed on the outer wall of the lifting shaft 205 and is slidably connected to the base 1. A connecting frame 2011 is fixedly connected to the top of the lifting plate 2010. The connecting frame 2011 is cross-shaped. The base 1 is provided with a lifting guide groove for the lifting plate 2010, the connecting frame 2011, and the connecting rotating plate 206 to slide up and down. Multiple connecting rotating plates 206 are circumferentially arranged on the top of the connecting frame 2011 and are rotatably connected by hinges. A flipping pressure plate 207 is rotatably connected to the top of the connecting rotating plate 206 by hinges. The flipping pressure plate 207 is rotatably connected to the connecting seat 5 by hinges. An edge-lifting mechanism 3 is vertically installed on the extrusion assembly. The edge-lifting mechanism 3 is used to detect whether the edges and corners of the corrugated paper are separated and to lift the separated corrugated paper.

[0020] In this embodiment: When using this device, corrugated paper is placed on the upper surface of multiple second suction cups 4. Then, the motor 208 is started to drive the switching plate 203 to rotate through the transmission shaft 2012. At the same time, the lower pressure plate 201 moves to the top of the connecting seat 5 under the drive of the switching plate 203. During this process, the switching plate 203 sleeves the outer wall of the lifting shaft 205 and the lifting block 2013 through the moving sleeve 202. At the same time, the connecting rod 3010 moves under the drive of the switching plate 203. Then, the motor 208 is stopped and the air pump is started to evacuate the airbag 209. At this time, the airbag 209 contracts due to the evacuation. Simultaneously, the lifting shaft 205, driven by the airbag 209, moves the moving sleeve 202 via the lifting block 2013, causing the switching plate 203 to descend. At this time, the lower pressure plate 201, driven by the switching plate 203, squeezes the corrugated paper located on the upper surface of the multiple second suction cups 4. During this process, the lifting plate 2010, driven by the lifting shaft 205, moves the connecting frame 201. 1. The corrugated paper descends along the inner wall of the base 1. At the same time, multiple connecting rotating plates 206 move the flipping pressure plate 207 through the hinge driven by the connecting frame 2011. At this time, the flipping pressure plate 207 rotates around the hinge connected to the connecting seat 5 as the axis, so that the flipping pressure plate 207 can be flipped to a horizontal state, so that the corrugated paper can be completely attached to the multiple second suction cups 4. Then, the air pump is started to extract the internal air of the second suction cup 4 in contact with the corrugated paper through the connecting seat 5, so that the corrugated paper can be completely fixed on the upper surface of the second suction cup 4. Then, air is pumped into the airbag 209. At this time, the airbag 209 expands due to inflation. Simultaneously, the lifting pull block 2013, driven by the lifting pull shaft 205 and the airbag 209, pushes the switching plate 203 to reset via the moving sleeve 202. At this time, the lower pressure plate 201 rises under the drive of the switching plate 203. At the same time, the connecting frame 2011, driven by the lifting pull plate 2010 and the lifting pull shaft 205, pushes the flipping pressure plate 207 to reset via the connecting plate 206. During this process, because the corrugated paper is attracted and fixed by the second suction cup 4, the corners of the corrugated paper bend under the pressure of the flipping pressure plate 207. Then, the motor 208 is started to drive the transmission shaft 2012 to reset the switching plate 203. At this time, the switching plate 203 rotates to separate the moving sleeve 202 from the lifting block 2013, and moves the lifting mechanism 3 to the top of the corrugated paper. The air pump is used to make the lifting mechanism 3 adsorb and fix the upper surface of the corner of the corrugated paper. Then, the air pump is used to pump air out the airbag 209 again, so that the flipping pressure plate 207 can be flipped to a horizontal state. During this process, if the corners of the corrugated paper separate as the flipping plate 207 flips, the corners of the corrugated paper need to be repaired. If the corrugated paper is still in the state of being attracted and bent by the edge-lifting mechanism 3, the condition of the corrugated paper is good and no repair is required, so as to detect whether the corners of the corrugated paper need to be repaired. When repairing corrugated paper, the edges and corners of the corrugated paper can be lifted by the edge lifting mechanism 3, and at the same time, the manual person can use a handheld glue gun to apply glue to the delaminated parts of the corrugated paper for repair.

[0021] In a preferred embodiment of the present invention, the edge-lifting mechanism 3 includes: A limiting sleeve 302 is set at one end of the top of the switching plate 203. The bottom end of the limiting sleeve 302 is fixedly connected to a connecting rod 3010 that slides vertically with the switching plate 203. A connecting guide plate 301 is sleeved on the outer wall of the bottom end of the connecting rod 3010. A spring 307 is sleeved on the outer wall of the connecting rod 3010. The two ends of the spring 307 are in contact with the outer walls of the switching plate 203 and the connecting guide plate 301, respectively. The bottom end of the connecting rod 3010 is rotatably connected to a gear 309 that is rotatably connected to the connecting guide plate 301 via a rotating shaft. Two racks 308 are symmetrically meshed on the outer wall of the gear 309. Two sliding frames 304 are fixedly connected to the ends of the two racks 308 that are far apart from each other and are sleeved on the outer wall of the connecting guide plate 301. The top of the device is fixedly connected to a movable pull rod 303 that is laterally slidably connected to the limiting sleeve 302. The movable pull rod 303 is L-shaped. One end of the movable pull rod 303, located outside the limiting sleeve 302, is rotatably connected to a positioning pressure block via a rotating shaft. The bottom ends of the two sliding frames 304 are rotatably connected to a rotating cylinder 306 via a rotating shaft. Multiple first suction cups 305 are fixedly connected circumferentially at equal intervals on the outer wall of the rotating cylinder 306. An air supply chamber is opened inside the rotating cylinder 306 that communicates with the inner cavities of the multiple first suction cups 305. A third air supply pipe is provided on one side of the sliding frame 304, penetrating from the sliding frame 304 to the air supply chamber of the rotating cylinder 306. The rotating cylinder 306 is rotatably connected to the third air supply pipe via a bearing. The rotating cylinder 306 is fixedly connected to an air pump via the third air supply pipe.

[0022] In this embodiment: when the switching plate 203 is reset, it drives the connecting rod 3010 to move above the corrugated paper. Then, the positioning block is rotated to release the lock on the limiting sleeve 302. At the same time, the spring 307 pushes the connecting guide plate 301 down by rebound. At this time, the rotating cylinder 306, driven by the connecting guide plate 301 through the sliding frame 304, contacts the surface of the corrugated paper bent by the flipping plate 207 through the first suction cup 305. At this time, the air pump is started to extract the air in the cavity of the first suction cup 305 that is in contact with the surface of the corrugated paper through the rotating cylinder 306, so that the first suction cup 305 adsorbs and fixes the upper surface of the corner of the corrugated paper. Then, the air pump is used to extract air from the airbag 209 again, so that the flipping plate 207 can be flipped to a horizontal state. During this process, if the corners of the corrugated paper separate as the flipping plate 207 flips, the corners of the corrugated paper need to be repaired. If the corrugated paper is still in the state of being attracted by the first suction cup 305, the condition of the corrugated paper is good and no repair is required, so as to detect whether the corners of the corrugated paper need to be repaired. When repairing corrugated paper, the movable lever 303 needs to be manually pushed to move along the inner wall of the limiting sleeve 302. At this time, one sliding frame 304 moves along the outer wall of the connecting guide plate 301 under the drive of the movable lever 303. Simultaneously, the gear 309, driven by the meshing of one rack 308, drives another rack 308 to move. At the same time, the two sliding frames 304, driven by the two racks 308 respectively, move the first suction cup 305 through the rotating cylinder 306. Meanwhile, the edges of the corrugated paper are moved by the first suction cup 305. The corrugated paper is lifted by the adsorption of 05, and then the separated parts of the corrugated paper are glued by hand using a glue gun. The above operation is then reversed to achieve convenient glue repair on the corners of the corrugated paper. At the same time, when repairing the other two corners of the corrugated paper, the moving rod 303 is pulled to drive the limiting sleeve 302 to rotate around the connecting rotating rod 3010 as the axis, so that the two rotating cylinders 306 can be displaced. This allows for separation detection of the other two corners of the corrugated paper and glue repair on the separated parts.

[0023] As a preferred embodiment of the present invention, the lifting sleeve 204 has two straight grooves symmetrically opened on its outer surface, the base 1 has a lifting groove for the lifting sleeve 204, the motor 208 and the lifting shaft 205 to slide up and down, and the lifting sleeve 204 has a rotating groove for the transmission shaft 2012 to rotate.

[0024] In this embodiment, the lifting sleeve 204 can slide up and down along the inner wall of the base 1 to push the motor 208 during the descent of the switching plate 203 via the linear slide groove.

[0025] In a preferred embodiment of the present invention, the connecting guide plate 301 is provided with a linear guide groove for the two racks 308 to slide laterally, and the two sliding frames 304 are each provided with a sliding sleeve groove that matches the outer wall of the connecting guide plate 301.

[0026] In this embodiment, the sliding frame 304 can slide along the outer wall of the connecting guide plate 301 under the drive of the rack 308 through the mutual cooperation of the linear guide groove and the sliding sleeve groove.

[0027] The working principle of this invention is as follows: When using this device, the moving rod 303 is pulled to drive the limiting sleeve 302 to rise. At this time, the connecting rotating rod 3010, driven by the limiting sleeve 302, drives the two sliding frames 304 to rise synchronously through the connecting guide plate 301. During this process, the connecting guide plate 301 compresses the spring 307 to retract, and then rotates the positioning pressure block to contact the upper surface of the switching rotating plate 203, thereby conveniently positioning the height of the sliding frame 304. It should be noted that: a heat dissipation vent is provided on one side of the base 1, which is connected to the inner cavity of the power supply 208 for lifting and lowering, and a dustproof net is installed inside the heat dissipation vent; Then, the corrugated paper is placed on the upper surface of multiple second suction cups 4. Then, the motor 208 is started to drive the switching plate 203 to rotate through the transmission shaft 2012. At the same time, the lower pressure plate 201 moves to the top of the connecting seat 5 under the drive of the switching plate 203. During this process, the switching plate 203 sleeves the outer wall of the lifting shaft 205 and the lifting block 2013 through the moving sleeve 202. At the same time, the connecting rod 3010 moves under the drive of the switching plate 203. Then, the motor 208 is stopped and the air pump is started to evacuate the airbag 209. At this time, the airbag 209 contracts due to the evacuation. Simultaneously, the lifting shaft 205, driven by the airbag 209, moves the moving sleeve 202 via the lifting block 2013, causing the switching plate 203 to descend. At this time, the lower pressure plate 201, driven by the switching plate 203, squeezes the corrugated paper located on the upper surface of the multiple second suction cups 4. During this process, the lifting plate 2010, driven by the lifting shaft 205, moves the connecting frame 201. 1. The corrugated paper descends along the inner wall of the base 1. At the same time, multiple connecting rotating plates 206 move the flipping pressure plate 207 through the hinge driven by the connecting frame 2011. At this time, the flipping pressure plate 207 rotates around the hinge connected to the connecting seat 5 as the axis, so that the flipping pressure plate 207 can be flipped to a horizontal state, so that the corrugated paper can be completely attached to the multiple second suction cups 4. Then, the air pump is started to extract the internal air of the second suction cup 4 in contact with the corrugated paper through the connecting seat 5, so that the corrugated paper can be completely fixed on the upper surface of the second suction cup 4. Then, air is pumped into the airbag 209. At this time, the airbag 209 expands due to inflation. Simultaneously, the lifting pull block 2013, driven by the lifting pull shaft 205 and the airbag 209, pushes the switching plate 203 to reset via the moving sleeve 202. At this time, the lower pressure plate 201 rises under the drive of the switching plate 203. At the same time, the connecting frame 2011, driven by the lifting pull plate 2010 and the lifting pull shaft 205, pushes the flipping pressure plate 207 to reset via the connecting plate 206. During this process, because the corrugated paper is attracted and fixed by the second suction cup 4, the corners of the corrugated paper bend under the pressure of the flipping pressure plate 207. Then, the motor 208 is started to drive the transmission shaft 2012 to reset the switching plate 203. At this time, the switching plate 203 rotates to separate the moving sleeve 202 from the lifting block 2013 and move the connecting rod 3010 above the corrugated paper. Then, the positioning pressure block is rotated to release the lock on the limiting sleeve 302. At the same time, the spring 307 pushes the connecting guide plate 301 down by rebound. At this time, the rotating cylinder 306, driven by the sliding frame 304 and the connecting guide plate 301, contacts the surface of the corrugated paper bent by the flipping pressure plate 207 through the first suction cup 305. At this time, the air pump is started to extract the air from the inner cavity of the first suction cup 305 that is in contact with the surface of the corrugated paper through the rotating cylinder 306, so that the first suction cup 305 adsorbs and fixes the upper surface of the corner of the corrugated paper. Then, the air pump is used to extract air from the airbag 209 again, so that the flipping pressure plate 207 can be flipped to a horizontal state. During this process, if the corners of the corrugated paper separate as the flipping plate 207 flips, the corners of the corrugated paper need to be repaired. If the corrugated paper is still in the state of being attracted and bent by the first suction cup 305, the condition of the corrugated paper is good and no repair is required, so as to detect whether the corners of the corrugated paper need to be repaired. When repairing corrugated paper, the movable lever 303 needs to be manually pushed to move along the inner wall of the limiting sleeve 302. At this time, one sliding frame 304 moves along the outer wall of the connecting guide plate 301 under the drive of the movable lever 303. Simultaneously, the gear 309, driven by the meshing of one rack 308, drives another rack 308 to move. At the same time, the two sliding frames 304, driven by the two racks 308 respectively, move the first suction cup 305 through the rotating cylinder 306. At the same time, the edges of the corrugated paper are lifted by the adsorption of the first suction cup 305, and then... By manually applying glue to the separated parts of the corrugated paper using a handheld glue gun, and then reversing the operation, convenient glue application and repair can be achieved for the corners of the corrugated paper. Simultaneously, when repairing the other two corners of the corrugated paper, pulling the movable lever 303 causes the limiting sleeve 302 to rotate around the connecting rotating rod 3010, facilitating the displacement of the two rotating cylinders 306. This allows for the detection and glue application of the separated corners of the corrugated paper, further improving the efficiency of glue application and repair for the corners of the corrugated paper.
