Description

Technical Field

[0001] The invention belongs to the technical field of carton processing, and specifically relates to a printing die-cutting production line for carton processing and a use method thereof. Background Art

[0002] Cartons are important carriers for product transportation and storage. In order to attract consumers' attention and improve the attractiveness and competitiveness of products, various patterns, texts, logos, etc. are often printed on the surface of cartons to make the cartons more beautiful and eye-catching. Product information can also be printed on the surface of cartons to facilitate consumers to understand the products. It also helps companies to carry out brand publicity and promotion. Due to the different sizes and shapes of products, cartons need to be cut before packaging to make the edges of cartons smoother and neater, and the cuts more precise, avoiding the problems of burrs and unevenness that may occur in manual cutting, and improving the overall quality and appearance of the packaging. At the same time, the die-cut cartons can better adapt to the requirements of automated packaging production lines, improve production efficiency, and reduce production costs.

[0003] When cutting cartons in the existing printing and die-cutting production line for carton processing, the cartons are directly placed at the bottom of the cutting knife, and the cutting knife is controlled to fall directly on the edge of the carton for cutting. When the cutting knife contacts the edge of the carton, the pressure can easily cause the carton to warp up, causing the carton to tilt and misalign at the bottom of the cutting knife, resulting in the edge of the carton being offset during cutting, resulting in waste. Therefore, improvements are needed. Summary of the invention

[0007] As a further solution of the present invention: Five conveyor shafts are equidistantly and rotatably mounted inside the conveyor frame. The positions of the linkage turntables correspond to those of the conveyor shafts, and one end of the conveyor shaft passes through the conveyor frame and is fixedly connected to the linkage turntable. One end of one of the conveyor shafts passes through the conveyor frame and is fixedly mounted with a bevel gear one. Three conveyor wheels are equidistantly and fixedly mounted on the surface of each conveyor shaft. A conveyor motor is provided on one side of the conveyor frame. The output end of the conveyor motor is fixedly mounted with a bevel gear two, and the bevel gear two meshes with the bevel gear one.

[0008] As a further solution of the present invention: The pressing mechanism includes two pressing side plates. Rectangular grooves one are respectively provided on both sides of the pressing side plates. Pressing sliding columns are fixedly mounted inside the rectangular grooves one. Pressing blocks are slidably mounted on the surfaces of the pressing sliding columns. Compression springs one are provided on the surfaces of the pressing sliding columns above the pressing blocks. A pressing frame is fixedly mounted between the four pressing blocks.

[0009] As a further solution of the present invention: A plurality of pressing rollers are equidistantly mounted at the bottom of the pressing frame. A rectangular groove two is provided at the central position of the pressing side plate. An electric push rod one is fixedly mounted at the bottom end of the rectangular groove two. Moving blocks are respectively fixedly mounted at the central positions on both sides of the pressing frame, and the moving blocks are slidably connected inside the rectangular groove two. The bottom of the moving block is fixedly connected to the top end of the electric push rod one.

[0010] As a further solution of the present invention: The pressing and cutting mechanism includes two concave-shaped frames. Electric push rods two are respectively fixedly mounted on both sides of the concave-shaped frames. A connecting plate is fixedly mounted at the bottom ends of the four electric push rods two.

Compression springs two are provided on the surfaces of the pressing columns between the connecting plate and the pressing plate. Cutting knives are symmetrically and fixedly mounted on both sides of the bottom of the connecting plate.

[0012] A usage method of a printing and die-cutting production line for carton processing, the usage method includes the following steps:

[0013] Control the first electric push rod to extend and lift the moving block upward inside the second rectangular groove, driving the pressing frame to move upward between the two pressing side plates until the pressing frame is lifted to a suitable height from the conveyor frame. At the same time, the pressing frame drives the pressing block to slide inside the corresponding first rectangular groove, causing the first pressing spring to be squeezed and deformed on the surface of the corresponding pressing slide column. After neatly stacking multiple cartons on the top of the conveyor frame and placing them on the surface of the corresponding conveyor wheel, control the first electric push rod to contract and drive the pressing frame to move downward. Under the elastic return of the first pressing spring, the pressing frame is smoothly pressed against the top of the cartons until the pressing roller is pressed against the top of the neatly stacked cartons;

[0014] Control the conveyor motor to start rotating. Under the meshing transmission of the first bevel gear and the second bevel gear, transfer the rotation of the conveyor motor to the conveyor shaft, driving the linkage turntable at one end of the conveyor shaft to rotate. Under the linkage action of the linkage bar, the five linkage turntables rotate synchronously, driving the five conveyor shafts to rotate synchronously inside the conveyor frame, causing the conveyor wheels to rub against the bottom of the cartons and pushing the cartons to move on the top of the conveyor frame past the baffle until the cartons move to the bottom of the elastic pressing pad;

[0015] Control the second electric push rod to extend, causing the connecting plate to press downward against the conveyor frame until the elastic pressing pad is tightly attached to the top of the cartons placed on the top of the conveyor frame. Control the second electric push rod to continue extending, gradually reducing the distance between the connecting plate and the pressing plate, causing the elastic pressing pad to press the cartons tightly against the surface of the conveyor wheels. At the same time, the cutting knife moves downward on both sides of the pressing plate and cuts tangentially to both sides of the cartons to cut the cartons. After cutting is completed, control the second electric push rod to contract, driving the connecting plate to move upward away from the conveyor frame, causing the second pressing spring to rebound, ensuring that the pressure of the elastic pressing pad on the cartons gradually decreases until the elastic pressing pad moves away from the cartons. Under the action of gravity, the cut carton waste falls on the surface of the conveyor belt from the gap between adjacent conveyor shafts. Start the conveying motor to drive the conveyor roller to rotate, causing the conveyor belt to rotate between the two installation side plates, discharging the waste falling on the top of the conveyor belt, and at the same time taking out the cut cartons located at the bottom of the elastic pressing pad, enabling the subsequent cartons located at the bottom of the pressing roller to continue to be conveyed to the bottom of the elastic pressing pad for cutting.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, by arranging electric push rod 2, elastic pressure pad, clamping spring 2 and cutting knife, when the carton moves from the top of the conveying frame to the bottom of the elastic pressure pad, the electric push rod 2 is controlled to extend, driving the connecting plate to move down and close to the carton until the elastic pressure pad is close to the top of the carton, and the electric push rod 2 is controlled to continue to extend, so that the connecting plate moves down and close to the clamping plate, and the clamping spring 2 is squeezed and deformed between the connecting plate and the clamping plate, and the clamping plate drives the elastic pressure pad to press down on the top of the carton under the rebound action of the clamping spring 2, and the carton is pressed against the corresponding conveying wheel surface. When the connecting plate moves down and close to the clamping plate, the connecting plate drives the cutting knives on both sides to move down and slide through the two sides of the clamping plate, and cuts the two sides of the carton pressed on the bottom of the elastic pressure pad, ensuring that the carton will not be lifted up when the edge of the carton is cut, so as to avoid the carton from lifting up during cutting, which causes the edge of the carton to be dislocated and offset during cutting.

[0018] 2. In the present invention, by setting a conveying wheel, a linkage bar, a clamping spring 1, a clamping roller and an electric push rod 1, the electric push rod 1 is controlled to extend and lift the moving block to move upward, driving the clamping frame to move upward between the two clamping side plates to a suitable height from the top of the conveying frame. At the same time, the clamping frame drives the clamping block to move up on the surface of the corresponding clamping slide bar to squeeze the clamping spring 1 to deform. After the neatly stacked cartons are placed on the top of the placement rack, the electric push rod 1 is controlled to contract and drive the moving block to move downward, so that the clamping frame moves downward until the clamping roller is close to the top of the carton. At the same time, the clamping spring 1 rebounds to ensure the clamping. When the rack moves downward, the four corners are evenly stressed and there will be no tilting or jamming. After the neatly stacked cartons are placed between the corresponding conveying wheels and the compacting rollers, the conveying motor is started to control a conveying shaft to rotate. Under the linkage action of the linkage bar, the five linkage shafts rotate synchronously, so that the conveying wheels on the surface of the linkage shafts rub against the bottom of the carton, pushing the carton to move on the top of the conveying rack until the carton is conveyed and moved to the bottom of the compacting and cutting mechanism for cutting, so as to avoid the situation where the pressure applied when the carton is placed on the top of the conveying wheel is small, causing the conveying wheel to slip on the bottom of the carton and affecting the conveyance of the carton.

[0026] The technical solutions of the present application will be further described in detail below in conjunction with specific embodiments.

[0027] As Figure 1-6 shown, the present invention provides a technical solution: a printing and die-cutting production line for carton processing, including a transmission and discharging mechanism 1. The transmission and discharging mechanism 1 includes two installation side plates 101. Four transmission rollers 102 are rotatably installed between the two installation side plates 101. A transmission belt 103 is provided on the surfaces of the four transmission rollers 102 between the two installation side plates 101. One end of one of the installation side plates 101 is fixedly installed with a conveyor motor 104, and the output end of the conveyor motor 104 is fixedly connected to one end of one of the transmission rollers 102. By providing the transmission belt 103, the waste materials at the edges of the cut cartons fall on the top of the transmission belt 103. The conveyor motor 104 is started to control the transmission roller 102 to rotate. Under the frictional action of the transmission belt 103, the transmission rollers 102 on both sides of the installation side plate 101 rotate synchronously, so that the transmission belt 103 moves to convey and concentrate the waste materials at the edges of the cartons. At the same time, the two transmission rollers 102 at the middle position of the transmission belt 103 support the transmission belt 103 to prevent the transmission belt 103 from sagging during the transmission process.

[0028] A transfer and discharging mechanism 1 is fixedly installed at the top of a transfer rack 2. A linkage mechanism 3 is arranged on one side of the transfer rack 2. The linkage mechanism 3 includes five linkage turntables 301. Connecting columns 302 are fixedly installed on the surfaces of the linkage turntables 301. A linkage bar 303 is rotatably installed on the surfaces between the five connecting columns 302. Five transfer shafts 201 are rotatably installed at equal intervals inside the transfer rack 2. The positions of the linkage turntables 301 correspond to those of the transfer shafts 201. One end of each transfer shaft 201 passes through the transfer rack 2 and is fixedly connected to the corresponding linkage turntable 301. One end of one of the transfer shafts 201 passes through the transfer rack 2 and is fixedly installed with a first bevel gear 203. Three transfer wheels 202 are fixedly installed at equal intervals on the surface of each transfer shaft 201. A transfer motor 204 is arranged on one side of the transfer rack 2. The output end of the transfer motor 204 is fixedly installed with a second bevel gear 205, and the second bevel gear 205 meshes with the first bevel gear 203. By providing the linkage bar 303 and the transfer shafts 201, when a cardboard box is placed on the top of the transfer rack 2 and is pressed against the surface of the transfer wheels 202, the transfer motor 204 is started. Through the transmission of the first bevel gear 203 and the second bevel gear 205, one transfer shaft 201 is controlled to rotate. At the same time, the linkage turntable 301 at one end of the transfer shaft 201 starts to rotate. Under the linkage action of the linkage bar 303, the five linkage turntables 301 are controlled to rotate synchronously, thereby driving the five transfer shafts 201 to rotate synchronously, so that the transfer wheels 202 rotate under the bottom of the cardboard box to convey the cardboard box.

[0029] One side of the top of the transfer rack 2 is fixedly installed with a pressing mechanism 4. The pressing mechanism 4 includes two pressing side plates 401. Rectangular grooves 402 are respectively arranged on both sides of the pressing side plates 401. Pressing sliding columns 403 are fixedly installed inside the rectangular grooves 402. Pressing blocks 404 are slidably installed on the surfaces of the pressing sliding columns 403. A first pressing spring 405 is arranged on the surface of the pressing sliding column 403 above the pressing block 404. A pressing frame 406 is fixedly installed between the four pressing blocks 404. Due to the provision of the first pressing springs 405, the four first pressing springs 405 are respectively compressed and rebounded on the tops of the corresponding pressing blocks 404, applying corresponding pressures to the four corners of the pressing frame 406 to ensure that the pressing frame 406 can move up and down smoothly and press on the top of the cardboard box.

[0030] A plurality of pressing rollers 407 are equidistantly installed at the bottom of the pressing frame 406, a rectangular groove 408 is provided at the central position of the pressing side plate 401, and an electric push rod 410 is fixedly installed at the bottom end of the rectangular groove 408, and moving blocks 409 are fixedly installed at the central positions of both sides of the pressing frame 406, and the moving blocks 409 are slidably connected to the inside of the rectangular groove 408, and the bottom of the moving block 409 is fixedly connected to the top of the electric push rod 410. By providing an electric push rod 410 and a pressing roller 407, the electric push rod 410 is controlled to extend and retract to drive the pressing frame 406 to move up and down between the two pressing side plates 401, so that the pressing roller 407 is pressed against the top of the carton, and at the same time, the inclined pressing frame 406 facilitates the insertion of the carton into the bottom of the pressing frame 406, and when the carton is inserted into the bottom of the pressing frame 406, the pressing roller 407 rolls on the top of the carton, thereby reducing the friction when the carton is inserted into the bottom of the pressing frame 406.

[0031] A pressing and cutting mechanism 6 is fixedly installed on one side of the top of the conveying frame 2 away from the pressing mechanism 4. The pressing and cutting mechanism 6 includes two concave frames 601. Electric push rods 602 are respectively inlaid and fixedly installed on both sides of the concave frames 601. Connecting plates 603 are fixedly installed at the bottom ends of the four electric push rods 602. Pressing columns 604 are slidably installed at the four corners of the bottom of the connecting plate 603. Pressing plates 605 are fixedly installed at the bottom ends of the four pressing columns 604. An elastic pressure pad 607 is fixedly installed at the bottom of the pressing plate 605. Because the elastic pressure pad 607 is provided, the electric push rod 602 controls the connecting plate 603 to move downward, so that the pressing plate 605 drives the elastic pressure pad 607 to move downward and press on the top of the carton, and the carton is pressed on the top of the conveying wheel 202 to ensure that the carton will not tilt when the edge of the carton is cut;

[0032] The top ends of the four clamping columns 604 pass through the connecting plate 603 and are fixedly installed with a rectangular limit plate 606. The surfaces of the clamping columns 604 located between the connecting plate 603 and the clamping plate 605 are provided with a clamping spring 2 608. Cutting knives 609 are symmetrically fixedly installed on both sides of the bottom of the connecting plate 603. By providing the clamping spring 2 608 and the cutting knife 609, after the elastic pressure pad 607 is pressed on the top of the carton, the connecting plate 603 is controlled to gradually approach the clamping plate 605, so that the clamping spring 2 608 is compressed and deformed. Under the rebound action of the clamping spring 2 608, the elastic pressure pad 607 is pressed against the top of the carton, thereby pressing and fixing the carton. At the same time, the connecting plate 603 drives the cutting knife 609 to move downward and slide over the clamping plate 605 to cut the edge of the carton during the movement.

[0033] A baffle plate 5 is fixedly installed on the top of the conveying frame 2 between the clamping mechanism 4 and the clamping and cutting mechanism 6. Because of the baffle plate 5, when the neatly stacked cartons are placed at the bottom of the clamping frame 406 for conveyance, the baffle plate 5 blocks the cartons, so that the cartons are conveyed one by one from the gap between the baffle plate 5 and the conveying frame 2.

[0034] A method for using a printing and die-cutting production line for carton processing, the method comprising the following steps:

[0035] Control the first electric push rod 410 to extend and jack up the moving block 409 to move upward inside the second rectangular groove 408, driving the pressing frame 406 to move upward between the two pressing side plates 401 until the pressing frame 406 is lifted to a suitable height from the conveyor frame 2. At the same time, the pressing frame 406 drives the pressing block 404 to slide inside the corresponding first rectangular groove 402, causing the first pressing spring 405 to be squeezed and deformed on the surface of the corresponding pressing sliding column 403. After placing multiple neatly stacked cartons on the top of the conveyor frame 2 and placing them on the surface of the corresponding conveyor wheels 202, control the first electric push rod 410 to contract and drive the pressing frame 406 to move downward. Under the rebounding action of the first pressing spring 405, the pressing frame 406 is smoothly pressed against the top of the cartons until the pressing roller 407 is pressed against the top of the neatly stacked cartons;

[0036] Control the conveyor motor 204 to start rotating. Under the meshing transmission of the first bevel gear 203 and the second bevel gear 205, the rotation of the conveyor motor 204 is transmitted to the conveyor shaft 201, driving the linkage turntable 301 at one end of the conveyor shaft 201 to rotate. Under the linkage action of the linkage bar 303, the five linkage turntables 301 rotate synchronously, driving the five conveyor shafts 201 to rotate synchronously inside the conveyor frame 2, causing the conveyor wheels 202 to rub against the bottom of the cartons and pushing the cartons to move on the top of the conveyor frame 2 past the baffle 5 until the cartons move to the bottom of the elastic pressing pad 607;

[0037] Control the second electric push rod 602 to extend to press down the connecting plate 603 against the conveyor frame 2 until the elastic pressing pad 607 is tightly attached to the top of the cartons placed on the top of the conveyor frame 2. Control the second electric push rod 602 to continue to extend, gradually reducing the distance between the connecting plate 603 and the pressing plate 605, causing the elastic pressing pad 607 to press the cartons tightly on the surface of the conveyor wheels 202. At the same time, the cutting knife 609 moves downward on both sides of the pressing plate 605 and cuts towards both sides of the cartons to cut the cartons. After the cutting is completed, control the second electric push rod 602 to contract, driving the connecting plate 603 to move upward away from the conveyor frame 2, causing the second pressing spring 608 to rebound, ensuring that the pressure of the elastic pressing pad 607 pressing on the cartons gradually decreases until the elastic pressing pad 607 moves away from the cartons. Under the action of gravity, the cut carton waste falls on the surface of the conveyor belt 103 from the gap between the adjacent conveyor shafts 201. Start the conveying motor 104 to drive the conveyor roller 102 to rotate, causing the conveyor belt 103 to rotate between the two mounting side plates 101 to discharge the waste falling on the top of the conveyor belt 103. At the same time, take out the cut cartons located at the bottom of the elastic pressing pad 607, so that the subsequent cartons located at the bottom of the pressing roller 407 are continuously conveyed to the bottom of the elastic pressing pad 607 for cutting.

The printing and die-cutting production line for carton processing according to claim 1, characterized in that: The clamping and cutting mechanism (6) comprises two concave frames (601), and two electric push rods (602) are respectively inlaid and fixedly installed on both sides of the concave frames (601), and connecting plates (603) are fixedly installed at the bottom ends of the four electric push rods (602), and clamping columns (604) are respectively slidably installed at the four corners of the bottom of the connecting plate (603), and clamping plates (605) are fixedly installed at the bottom ends of the four clamping columns (604).

7. A printing and die-cutting production line for carton processing according to claim 6, characterized in that: An elastic pressure pad (607) is fixedly installed at the bottom of the clamping plate (605), and a rectangular limiting plate (606) is fixedly installed on the top of the four clamping columns (604) through the connecting plate (603), and a clamping spring 2 (608) is provided on the surface of the clamping column (604) located between the connecting plate (603) and the clamping plate (605), and cutting knives (609) are symmetrically fixedly installed on both sides of the bottom of the connecting plate (603).

8. A method for using a printing and die-cutting production line for carton processing, according to any one of claims 1 to 7, characterized in that: The method of use comprises the following steps: Control the electric push rod 1 (410) to extend and lift the moving block (409) to move upward inside the rectangular groove 2 (408), driving the clamping frame (406) to move upward between the two clamping side plates (401) until the clamping frame (406) is lifted to a suitable height from the conveying frame (2). At the same time, the clamping frame (406) drives the clamping block (404) to slide inside the corresponding rectangular groove 1 (402), causing the clamping spring 1 (405) to be squeezed and deformed on the surface of the corresponding clamping slide column (403). After the neatly stacked cartons are neatly stacked and placed on the top of the conveying frame (2) on the surface of the corresponding conveying wheel (202), the electric push rod 1 (410) is controlled to contract and drive the clamping frame (406) to move downward. Under the rebound action of the clamping spring 1 (405), the clamping frame (406) is steadily pressed against the top of the carton until the clamping roller (407) is pressed against the top of the neatly stacked carton. The conveying motor (204) is controlled to start rotating. Under the meshing transmission of the bevel gear 1 (203) and the bevel gear 2 (205), the rotation of the conveying motor (204) is transmitted to the conveying shaft (201), driving the linkage turntable (301) at one end of the conveying shaft (201) to rotate. Under the linkage action of the linkage bar (303), the five linkage turntables (301) are rotated synchronously, driving the five conveying shafts (201) to rotate synchronously inside the conveying frame (2), causing the conveying wheel (202) to rub against the bottom of the carton, pushing the carton to move on the top of the conveying frame (2) through the baffle plate (5), until the carton moves to the bottom of the elastic pressure pad (607); The second electric push rod (602) is controlled to extend so that the connecting plate (603) is pressed downward toward the conveying frame (2) until the elastic pressure pad (607) is pressed against the top of the carton placed on the top of the conveying frame (2). The second electric push rod (602) is controlled to continue to extend so that the distance between the connecting plate (603) and the pressing plate (605) is gradually reduced, so that the elastic pressure pad (607) presses the carton against the surface of the conveying wheel (202). At the same time, the cutting knife (609) moves downward on both sides of the pressing plate (605) to cut the carton. After the cutting is completed, the second electric push rod (602) is controlled to retract, driving the connecting plate (603) to move upward away from the conveying frame (2), so that the pressing spring (608) The elastic pressure pad (607) rebounds to ensure that the pressure of the elastic pressure pad (607) on the carton gradually decreases until the elastic pressure pad (607) is away from the carton. Under the action of gravity, the cut carton waste falls from the gap between the adjacent conveying shafts (201) onto the surface of the conveyor belt (103). The conveying motor (104) is started to drive the conveying roller (102) to rotate, so that the conveyor belt (103) rotates between the two mounting side plates (101), and the waste falling on the top of the conveyor belt (103) is discharged. At the same time, the cut carton located at the bottom of the elastic pressure pad (607) is taken out, so that the subsequent carton located at the bottom of the clamping roller (407) is continuously conveyed to the bottom of the elastic pressure pad (607) for cutting.
