Description

Technical Field

[0001] The present invention relates to the technical field of carton processing, and specifically relates to a die-cutting and punching device for beer card cartons and its usage method. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. At the same time, cartons are also divided into knife cards, flat cards and beer cards. Knife cards and flat cards are more common in current cartons. Among them, since the overall shape of the beer card is irregular, it is usually formed by separate cutting and punching. Currently, the cutting work of beer card cartons is usually carried out using a cutting device. After the existing cutting work of beer card cartons is completed, it is still necessary to manually separate the finished products from the waste materials, and the overall use is relatively inconvenient.

[0003] The prior art obtains the finished cardboard by sequentially passing the cardboard main body through punching and cutting processes. However, in the prior art, if the order of first cutting and then punching is adopted, at this time, the shape of the finished cardboard is irregular, resulting in the position of the finished cardboard being not easy to determine during the punching process, and it is easy to deviate from the punching position, resulting in defective products. If the order of first punching and then cutting is adopted, after the punching process is completed, when transferring the cardboard main body to the cutting area, the orientation of the finished cardboard needs to be adjusted first, otherwise, the position of the holes on the cut finished cardboard will be incorrect, resulting in defective products. And in either case, it is necessary to face the secondary transfer and position determination of the cardboard main body, which takes a lot of time and leads to low overall production efficiency.

Specific embodiments

[0032] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0033] See Figures 1 - 5As shown in the figure, a punching and cutting device for beer card cartons includes a base 1, a Z-axis linear movement component 2, an X-Y axis linear movement component 3, and a punching and cutting component 4. The punching and cutting component 4 includes a fixed block 41, a movable ring 42, a punching structure 43, and a cutting structure 44. In the base 1, there is a first conveyor belt 11 capable of transporting the cardboard body and a second conveyor belt for transporting the finished cardboard. The second conveyor belt 12 is below the first conveyor belt 11 and the first conveyor belt 11 and the second conveyor belt 12 are parallel. The transportation direction of the first conveyor belt 11 is perpendicular to the moving direction of the output end of the Z-axis linear movement component 2. The Z-axis linear movement component 2 is on the base 1 and the Z-axis linear movement component 2 can drive the X-Y axis linear movement component 3 to move. A first connecting shaft 411 is movably arranged inside the fixed block 41, and the axis of the first connecting shaft 411 is parallel to the Z-axis. The X-Y axis linear movement component 3 can drive the fixed block 41 to move in the horizontal plane. The movable ring 42 is rotatably connected to the fixed block 41, and the axis of the movable ring 42 is arranged obliquely with respect to the Z-axis. A part of the movable ring 42 is below the fixed block 41 and the part of the movable ring 42 that is not below the fixed block 41 is higher than the bottom surface of the fixed block 41. Two second connecting shafts 421 are movably arranged on the movable ring 42, and the two second connecting shafts 421 are evenly distributed around the axis of the movable ring 42. When the second connecting shaft 421 is directly below the first connecting shaft 411, the second connecting shaft 421 is coaxial with and in transmission connection with the first connecting shaft 411. The punching component is detachably fixed to any one of the second connecting shafts 421, and the cutting component is detachably fixed to the other second connecting shaft 421.

[0034] Place the cardboard main body on the first conveyor belt 11. The first conveyor belt 11 moves the cardboard main body into the working range of the X-Y axis linear movement component 3. At this time, the first conveyor belt 11 stops transporting. Control the Z-axis linear movement component 2 to make the fixed block 41 and the movable ring 42 approach the cardboard main body. Control the rotation of the movable ring 42 to move the second connecting shaft 421 connected with the punching structure 43 below the first connecting shaft 411. At this time, the second connecting shaft 421 is coaxially driven and connected with the first connecting shaft 411. The punching structure 43, the X-Y axis linear movement component 3 and the Z-axis linear movement component 2 cooperate to punch the cardboard main body. Subsequently, control the Z-axis linear movement component 2 to move the punching structure 43 away from the cardboard main body. Control the rotation of the movable ring 42 to move the second connecting shaft 421 connected with the cutting structure 44 below the first connecting shaft 411. At this time, the second connecting shaft 421 is coaxially driven and connected with the second connecting shaft 421. The cutting structure 44, the X-Y axis linear movement component 3 and the Z-axis linear movement component 2 cooperate to cut the cardboard main body. Subsequently, control the Z-axis linear movement component 2 to move the punching and cutting component 4 away from the cardboard main body. The finished cardboard falls on the second conveyor belt 12 and is transported out of the base 1. The remaining cardboard main body is transported out of the base 1 on the first conveyor belt 11. Compared with the prior art, the movable ring 42 of the present invention drives the punching structure 43 and the cutting structure 44 to switch positions, so that the cardboard main body can be kept in one position for punching and cutting work. Through the inclined setting of the movable ring 42 and the cooperation of the first connecting shaft 411 and the second connecting shaft 421, it is ensured that only one of the punching structure 43 and the cutting structure 44 can contact the cardboard main body and work at the same time. Thus, the punching and cutting work can be quickly completed without secondary transfer and position determination of the cardboard main body, reducing the manual work burden and the probability of producing defective products. At the same time, the space occupied by the overall equipment is also reduced, which is convenient to use and improves the overall production efficiency.

[0035] See Figures 3 - 6 As shown in the figure: The movable ring 42 further includes a movable frame 422. The number of movable frames 422 is the same as the number of second connecting shafts 421, and each second connecting shaft 421 is arranged inside the movable frame 422. The connection line of the two open ends of the movable frame 422 is parallel to the axis of the second connecting shaft 421. The movable frame 422 is rotatably arranged on the movable ring 42, and the rotation axis of the movable frame 422 is parallel to the diameter of the movable ring 42. The movable frame 422 can drive the second connecting shaft 421 to move. When the movable frame 422 moves directly below the first connecting shaft 411, the movable frame 422 rotates to make the second connecting shaft 421 coaxial with the first connecting shaft 411.

[0036] When the movable ring 42 rotates and the movable frame 422 is not directly below the first connecting shaft 411, the movable frame 422 rotates following the movable ring 42 while maintaining its own state unchanged. The second connecting shaft 421 inside the movable frame 422 rotates following the movable ring 42 while keeping its axis parallel to the axis of the movable ring 42. When the movable frame 422 is directly below the first connecting shaft 411, the movable frame 422 drives the second connecting shaft 421 to rotate so that the second connecting shaft 421 is coaxial with the first connecting shaft 411. Compared with the prior art, the movable frame 422 of the present invention enables the second connecting shaft 421 to switch between an inclined state and a vertical state, so that except for the height, other aspects of the punching structure 43 and the cutting structure 44 do not change when they are in the working state and the non-working state.

[0037] See Figures 3 - 6 As shown: The movable ring 42 further includes movable blocks 423. The number of movable blocks 423 is the same as the number of movable frames 422, and one movable block 423 is slidably arranged in each movable frame 422. The sliding direction of the movable block 423 is parallel to the axis of the second connecting shaft 421. The second connecting shaft 421 is rotatably arranged inside the movable block 423, and both ends of the second connecting shaft 421 can communicate with the outside of the movable block 423. A first magnetic member 4231 is fixedly arranged at one end of the movable block 423 close to the fixed block 41, and a second magnetic member 412 capable of magnetic cooperation with the opposite sex of the first magnetic member 4231 is fixedly arranged on the bottom surface of the fixed block 41. When the movable block 423 contacts the fixed block 41, the first connecting shaft 411 is in transmission connection with the second connecting shaft 421.

[0038] When the movable frame 422 moves to directly below the first connecting shaft 411, the first magnetic member 4231 and the second magnetic member 412 cooperate to make the movable block 423 move upward along the axis of the first connecting shaft 411. As the top surface of the movable block 423 continuously levels with the bottom surface of the fixed block 41, the movable frame 422 also rotates continuously. Compared with the prior art, the movable block 423 of the present invention causes the height to change when the state of the second connecting shaft 421 changes, so as to ensure that there is no deviation in the rotation angle of the movable frame 422 driving the second connecting shaft 421.

[0039] See Figures 6 - 8 As shown: The movable ring 42 further includes a fixed rod 424. The fixed rod 424 is detachably connected to the fixed ring. The fixed rod 424 is coaxial with the rotation axis of the movable frame 422, and the movable frame 422 is provided with a first fixing hole 4221 through which the fixed rod 424 can pass, and the movable block 423 is provided with a fixed groove 4232 through which the fixed rod 424 can slide.

[0040] Remove the fixed rod 424 from the movable ring 42. The fixed rod 424 will sequentially leave the fixed groove 4232 and the first fixing hole 4221. Subsequently, the movable frame 422 will drive the movable block 423 to disengage from the movable ring 42. Compared with the prior art, the fixed rod 424 of the present invention provides a support point to connect the movable frame 422 and the movable ring 42, so that the movable frame 422 and the parts inside it can be conveniently and quickly disassembled from the movable ring 42 for maintenance and replacement.

[0041] See Figures 6 - 8 As shown in the figure: The movable ring 42 further includes a movable strip 425 and a first spring 426. The movable strip 425 is slidably disposed in the fixed groove 4232. The sliding direction of the movable strip 425 is parallel to the axis direction of the second connecting shaft 421. A second fixing hole 4251 through which the fixed rod 424 can pass is formed in the center of the movable strip 425. Two first springs 426 that are mirror-symmetrically distributed with the second fixing hole 4251 as the center are fixedly disposed at both ends of the movable strip 425 along its sliding direction. The other ends of the first springs 426 are fixedly connected to the ends of the fixed groove 4232.

[0042] When the movable frame 422 has not moved to directly below the first connecting shaft 411, at this time, the first springs 426 at the upper and lower ends of the movable strip 425 are both in a normal state. The movable strip 425 is at the central position of the movable block 423, the movable block 423 is at the central position of the movable frame 422, and the movable block 423 and the movable frame 422 are in a relatively stationary state at this time to rotate with the movable ring 42. Compared with the prior art, the movable strip 425 and the first spring 426 of the present invention limit the positional relationship between the movable block 423 and the movable frame 422 during a certain period of time, so as to ensure that the first magnetic member 4231 and the second magnetic member 412 can perform magnetic cooperation work when the movable block 423 just enters below the first connecting shaft 411.

[0043] See Figures 6 - 8 As shown in the figure: The movable ring 42 further includes a movable rod 427 and a second spring 428. The movable rod 427 is slidably disposed on the movable frame 422 along the axial direction of the fixed rod 424. Two movable rods 427 are disposed at both ends of the movable frame 422 where the first fixing hole 4221 is formed. The two movable rods 427 are evenly distributed around the axis of the first fixing hole 4221 at the corresponding end. An arc-shaped groove 429 that can be slidably engaged with the movable rod 427 is formed on the movable ring 42. Both ends of the arc-shaped groove 429 are provided with inclined surfaces. One end of the second spring 428 is fixedly connected to the movable rod 427, and the other end of the second spring 428 abuts against the movable block 423.

[0044] When the movable frame 422 moves to directly below the first connecting shaft 411, at this time, the movable rod 427 slides to the end inside the arc-shaped groove 429. While the second spring 428 is compressed, a part of the movable rod 427 shrinks into the movable frame 422. When the movable frame 422 moves to directly below the first connecting shaft 411, the second spring 428 resumes its deformation and pushes the movable rod 427 to extend outside the movable frame 422. The cooperation between the movable rod 427 and the inclined surface on the arc-shaped groove 429 causes the movable frame 422 to drive the second connecting shaft 421 to rotate to an inclined state. Compared with the prior art, the movable rod 427, the second spring 428, and the arc-shaped groove 429 of the present invention limit the positional relationship between the movable frame 422 and the movable ring 42 during some time periods, thereby ensuring that the punching mechanism and the cutting structure 44 do not shake when following the rotation of the movable ring 42.

[0045] See Figures 7 - 10 As shown in the figure: The fixed block 41 further includes a trigger bar 413. The trigger bar 413 is slidably arranged along the Z-axis direction inside the fixed block 41, and the trigger bar 413 can extend outside the bottom surface of the fixed block 41. The movable block 423 located directly below the first connecting shaft 411 can contact the trigger bar 413. A clamping block 4111 is fixedly arranged at the lower end of the first connecting shaft 411 along the Z-axis direction. A clamping groove 4211 for inserting the clamping block 4111 is provided at one end of the second connecting shaft 421 close to the fixed block 41. When the trigger bar 413 moves into the fixed block 41, the first connecting shaft 411 slides, so that the clamping block 4111 is inserted into the clamping groove 4211.

[0046] When the second connecting shaft 421 has not moved to directly below the first connecting shaft 411, at this time, the trigger bar 413 protrudes outside the fixed block 41, and the clamping block 4111 shrinks into the fixed block 41. When the second connecting shaft 421 moves to directly below the first connecting shaft 411, the movable block 423 pushes the trigger bar 413 to move into the fixed block 41, and the clamping block 4111 moves downward and is inserted into the clamping groove 4211. Compared with the prior art, the trigger bar 413 of the present invention enables the clamping block 4111 to protrude from the fixed block 41 at an appropriate time and complete the connection with the clamping groove 4211, thereby ensuring that the first connecting shaft 411 is not affected by the external environment during the non-working state and improving the service life of the first connecting shaft 411.

[0047] See Figures 9 - 10As shown: The fixed block 41 further includes a third spring 414 and a limiting strip 415. The third spring 414 is fixedly arranged between the trigger strip 413 and the fixed block 41. The limiting strip 415 is slidably arranged inside the fixed block 41 along the diameter direction of the first connecting shaft 411. A triangular annular groove 4112 is coaxially formed on the first connecting shaft 411. One end of the limiting strip 415 close to the first connecting shaft 411 is provided with an inclined surface capable of slidingly cooperating with the triangular annular groove 4112. A guide shaft 4151 is fixedly arranged at the end of the limiting strip 415 far from the first connecting shaft 411. The guide shaft 4151 is perpendicular to the sliding direction of the limiting strip 415 and perpendicular to the axis of the first connecting shaft 411. An inclined guide groove 4131 capable of slidingly cooperating with the guide shaft 4151 is formed on the trigger strip 413. The number of the limiting strips 415 is two, and the two limiting strips 415 are evenly distributed around the axis of the first connecting shaft 411. The number of the trigger strips 413 is equal to the number of the limiting strips 415.

[0048] When the trigger strip 413 moves upward along the axis direction of the first connecting shaft 411, the third spring 414 undergoes compressive deformation. The sliding of the guide groove 4131 cooperating with the guide shaft 4151 causes the two limiting strips 415 to move away from each other along the diameter direction of the first connecting shaft 411. Under the influence of its own gravity, the first connecting shaft 411 descends along its own axis direction, so that the triangular annular groove 4112 slidesly cooperates with the inclined surface on the limiting strip 415 again. When the movable frame 422 disengages from below the first connecting shaft 411, the third spring 414 undergoes recovery deformation and pushes the trigger strip 413 to move downward along the axis direction of the first connecting shaft 411. Compared with the prior art, the third spring 414 and the limiting strip 415 of the present invention enable the first connecting shaft 411 to reciprocally move up and down along its own axis, thereby ensuring that the first connecting shaft 411 can be in transmission connection with the second connecting shaft 421 multiple times.

[0049] See Figures 9 - 10 As shown: The fixed block 41 further includes a first servo motor 416, a second servo motor 417 and a fourth spring 418. The first servo motor 416 is fixedly arranged outside the fixed block 41 and the first servo motor 416 is in transmission connection with the first connecting shaft 411. The second magnetic member 412 is an electromagnet, and the second magnetic member 412 and the first servo motor 416 start and stop synchronously. The second servo motor 417 is fixedly arranged outside the fixed block 41 and the second servo motor 417 is in transmission connection with the movable ring 42. The fourth spring 418 is arranged above the first connecting shaft 411 and can push the first connecting shaft 411 to slide.

[0050] Control the second servo motor 417 to rotate the movable ring 42 by a fixed angle. The movable frame 422 moves to directly below the first connecting shaft 411. Start the first servo motor 416. At the same time, the second magnetic member 412 is powered on. The fourth spring 418 pushes the first connecting shaft 411 to move. The first connecting shaft 411 and the second connecting shaft 421 complete the transmission connection. Turn off the first servo motor 416. The second magnetic member 412 loses its magnetism. The first connecting shaft 411 and the second connecting shaft 421 are disengaged from the transmission connection. Compared with the prior art, the cooperation of the first servo motor 416, the second servo motor 417, the fourth spring 418 and the second magnetic member 412 enables the first connecting shaft 411 to stably disengage from the second connecting shaft 421 and contract into the fixed block 41, so that the movable frame 422 can drive the second connecting shaft 421 to leave directly below the first connecting shaft 411.

[0051] See Figures 1 - 5 shown in the figure: A method for cutting and punching a beer card carton, using the described beer card carton cutting and punching device, includes the following steps:

[0052] S1. Place the cardboard main body on the first conveyor belt 11. The first conveyor belt 11 moves the cardboard main body into the working range of the X-Y axis linear movement assembly 3. Control the Z-axis linear movement assembly 2 to make the fixed block 41 and the movable ring 42 approach the cardboard main body.

[0053] S2. Control the rotation of the movable ring 42 to move the second connecting shaft 421 connected with the punching structure 43 to below the first connecting shaft 411. At this time, the second connecting shaft 421 is coaxially connected with the first connecting shaft 411 for transmission. The punching structure 43, the X-Y axis linear movement assembly 3 and the Z-axis linear movement assembly 2 cooperate to punch the cardboard main body.

[0054] S3. Control the rotation of the movable ring 42 to move the second connecting shaft 421 connected with the cutting structure 44 to below the first connecting shaft 411. At this time, the second connecting shaft 421 is coaxially connected with the second connecting shaft 421 for transmission. The cutting structure 44, the X-Y axis linear movement assembly 3 and the Z-axis linear movement assembly 2 cooperate to cut the cardboard main body. The finished cardboard falls on the second conveyor belt 12 and is transported away.

[0055] Compared with the prior art, the movable ring 42 of the present invention drives the punching structure 43 and the cutting structure 44 to switch positions, so that the cardboard body can be kept in one position for punching and cutting operations. Through the inclined setting of the movable ring 42 and the cooperation of the first connecting shaft 411 and the second connecting shaft 421, it is ensured that only one of the punching structure 43 and the cutting structure 44 can contact the cardboard body and perform operations at the same time. Thus, the cutting and punching operations can be quickly completed without secondary transfer and position determination of the cardboard body, reducing the manual work burden and the probability of defective products, while also reducing the space occupied by the overall equipment, facilitating use and improving the overall production efficiency.

[0056] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
