Description

Technical Field

[0001] This utility model relates to the field of cigarette box processing technology, and in particular to a corner-breaking device for cigarette box processing. Background Technology

[0002] During the printing and production process of cigarette boxes, after printing, the boxes need to be cut so that the unprocessed packaging paper has bendable side folds. However, because the cuts on the side folds of the cigarette box paper are small, the cut paper and the side folds will come into contact after cutting, resulting in the side folds not separating from the paper. Therefore, it is necessary to manually pry open the side folds that have not separated at the cuts in the later stage. However, in actual operation, manually prying the corners is too inefficient and cannot be applied to the efficient production of cigarette boxes. Summary of the Invention

[0003] This utility model provides a corner-breaking device for cigarette box processing to solve the aforementioned technical problems.

[0004] The present invention adopts the following technical solution: it includes a base plate; a pad for placing cigarette box paper is provided on the base plate; a corner-breaking mechanism for bending the side corners of the paper is provided above the pad; the corner-breaking mechanism is mounted on the base plate by a bracket; a driving mechanism for driving the corner-breaking mechanism is provided on the bracket; and notches are provided on the pad corresponding to the two side corners of the cigarette box paper.

[0005] Preferably, the corner-breaking mechanism includes a support plate; connecting plates are provided on the lower parts of both sides of the support plate, the connecting plates are movably connected to the lower parts of the support plate, and the connecting plates on both sides of the support plate can be translated to the sides of the support plate respectively; a pressure block is fixedly provided below each connecting plate, and the bottom side of the pressure block facing the part between the support plates is designed with a slope; the driving mechanism is a driving electric cylinder, the driving electric cylinder is fixedly mounted on the bracket in an inverted state, the output end of the driving electric cylinder passes through the bracket and extends downward and is fixedly connected to the support plate, and the output end of the driving electric cylinder can drive the support plate to rise and fall when it extends and retracts.

[0006] Preferably, a pressure plate for positioning the paper is provided below the support plate; two support rods are provided on the top of the pressure plate, the bottom ends of the two support rods are fixedly connected to the pressure plate, and the top ends of the two support rods extend from the support plate from top to bottom and extend upward for a certain distance, and a stop is fixedly provided on the extended ends of the top ends of the two support rods; the two support rods can slide up and down on the support plate.

[0007] Preferably, guide plates are provided below the bracket and on both sides of the support plate, and the top of the guide plates are fixedly connected to the bracket; guide grooves are provided on both ends of the connecting plates on both sides of the support plate on the guide plates; each connecting plate is provided with a guide rod at both ends, one end of the guide rod is fixedly connected to the corresponding connecting plate, and the other end of the guide rod extends into the guide groove on the guide plate and can move within the guide groove.

[0008] Preferably, the guide groove is designed vertically, and the middle section of the guide groove is bent and then extended at an incline towards the corresponding connecting plate.

[0009] Preferably, each of the two support rods is fitted with a tension spring, which is located between the stop block at the top of the support rod and the support plate. The two ends of the tension spring are fixedly connected to the corresponding stop block and the support plate, respectively. Under the tension of the two ends of the tension spring, the stop block can be pulled towards the support plate.

[0010] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects: Firstly, this utility model achieves automated corner-breaking processing of cigarette box paper side corners through the cooperation of the drive mechanism and the corner-breaking mechanism, replacing traditional manual operation. Compared with the low efficiency of manual corner breaking, this device can precisely control the operation of the drive cylinder through the control system, completing a single corner-breaking process in a short time with strong continuity. It can be directly integrated into the automated cigarette box production line, effectively meeting the needs of large-scale and high-efficiency cigarette box processing.

[0011] Secondly, the clamping structure formed by the pressure plate and pad in the device, combined with the tension spring design on the support rod, provides continuous and stable positioning of the cigarette box paper during processing: the pressure plate first contacts and initially fixes the paper body; subsequently, when the support plate descends, the tension spring applies downward pulling force to the support rod through the stop block, ensuring that the pressure plate maintains stable pressure on the paper and preventing the paper from skewing or shifting during corner bending. Simultaneously, the inclined surface design at the bottom of the pressure block, in conjunction with the inclined trajectory of the guide groove, precisely applies a "press-separate" force to the side corner fold, ensuring complete separation of the corner from the cut of the paper body, and that the corner bending trajectory is uniform, improving the consistency of cigarette box processing quality.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] This utility model provides a corner-bending device for processing cigarette boxes, including a base plate 1; a pad 11 for placing cigarette box paper is provided on the base plate 1; a corner-bending mechanism 2 for bending the side corners of the paper is provided above the pad 11; the corner-bending mechanism 2 is mounted on the base plate 1 via a bracket 12; and a drive mechanism 13 for driving the corner-bending mechanism 2 is provided on the bracket 12. In use, the paper that has been cut and has formed side folds can be placed on the pad 11 by the paper conveying equipment. Then, the corner bending mechanism 2 is driven by the operation of the drive mechanism 13 to bend the side folds formed by the cuts on both sides of the paper. This causes the side folds on both sides of the paper to bend downward and separate from the paper body, which facilitates the bending and bonding process of the side folds of the paper in the subsequent cigarette box processing.

[0018] In a further preferred embodiment, the pad 11 is provided with notches 111 corresponding to the two side corners of the cigarette box paper; (The paper conveying device in this patent application is prior art and is not within the scope of protection of this patent application. It is only used as a conveying device when the paper is placed on the pad 11.) In use, the paper can be positioned on the pad 11 by using the paper conveying device, so that the side corners that need to be bent are located at the notches 111 on both sides of the pad 11, so that the notches 111 can provide room for the side corners to bend downward.

[0019] In a further preferred embodiment, the corner-breaking mechanism 2 includes a support plate 21; connecting plates 22 are provided on the lower parts of both sides of the support plate 21, the connecting plates 22 are movably connected to the lower parts of the support plate 21, and the connecting plates 22 on both sides of the support plate 21 can be translated to the sides of the support plate 21 respectively; a pressure block 23 is fixedly provided below each connecting plate 22, and the bottom side of the pressure block 23 facing the part between the support plates 21 is designed with a slope; the driving mechanism 13 is a driving electric cylinder, which is fixedly mounted on the bracket 12 in an inverted state, and the driving electric cylinder... The output end passes through the bracket 12 and extends downwards, and is fixedly connected to the support plate 21. When the output end of the drive cylinder extends and retracts, it can drive the support plate 21 to rise and fall. A pressure plate 24 for positioning the paper is provided below the support plate 21. Two support rods 25 are provided on the top of the pressure plate 24. The bottom ends of the two support rods 25 are fixedly connected to the pressure plate 24, and the top ends of the two support rods 25 extend from the support plate 21 from top to bottom and extend upwards for a certain distance. A stop block 251 is fixedly provided on the extended end of the top end of the two support rods 25. The two support rods 25 can slide up and down on the support plate 21.

[0020] In a further preferred embodiment, guide plates 3 are provided below the bracket 12 and on both sides of the support plate 21, and the top of the guide plates 3 are fixedly connected to the bracket 12. The guide plate 3 is provided with guide grooves 31 at both ends of the connecting plates 22 on both sides of the support plate 21; Each of the connecting plates 22 is provided with a guide rod 221 at both ends. One end of the guide rod 221 is fixedly connected to the corresponding connecting plate 22, and the other end of the guide rod 221 extends into the guide groove 31 on the guide plate 3 and can move within the guide groove 31. The guide groove 31 is designed vertically, and the middle section of the guide groove 31 is bent and then extends obliquely towards the corresponding connecting plate 22. The electric drive cylinder in this application is prior art and is equipped with a matching control system; When in use, the operating control system sends a running command to the drive cylinder, causing the output end of the drive cylinder to extend downward and drive the support plate 21 to descend a certain distance. After the pressure plate 24 below the support plate 21 comes into contact with the main body of the paper, the gravity of the pressure plate 24 and the pad 11 work together to clamp the paper. The electric cylinder output then continues to operate, causing the support plate 21 to descend further. During this process, since the two support rods 25 at the top of the pressure plate 24 can slide up and down on the support plate 21, as the support plate 21 continues to descend, the two support rods 25 at the top of the pressure plate 24 will extend upwards onto the support plate 21, and the pressure plate 24 will continuously apply pressure to the paper. As the support plate 21 continues to descend, it can drive the connecting plates 22 on both sides and the pressure block 23 to move downwards synchronously. Since the guide rods 221 on the connecting plates 22 all extend into the corresponding guide grooves 31, When the connecting plate 22 descends with the support plate 21, the guide rods 221 at both ends of the connecting plate 22 will move downward in a straight line along the vertical trajectory of the upper half of the guide groove 31. When the guide rods 221 move to the bending part in the middle of the guide groove 31, the inclined part of the lower half of the guide groove 31 will pull the guide rods 221, causing the guide rods 221 to move in an inclined direction along the inclined trajectory towards both sides of the support plate 21, and causing the corresponding two connecting plates 22 and the pressure block 23 to move while moving downward in an inclined direction towards the side folding angle of the paper. When the bottom of the pressure block 23 makes initial contact with the side fold of the paper, the pressure block 23 applies downward pressure to the side fold, thereby forming a crease at the connection between the side fold and the paper body. As the pressure block 23 gradually tilts and descends outward, the inclined surface at the bottom of the pressure block 23 applies outward pressure to the side fold after it has been pressed down, causing the side fold of the paper to separate from the cut part of the paper body due to the pressure of the pressure block 23. This allows the side folds on both sides of the paper to bend downward and be placed on two horizontal planes with the paper body, thus making it easier for the side folds after the cut part is separated from the paper to undergo subsequent bending and bonding processes with greater strength. In a further preferred embodiment, each of the two support rods 25 is fitted with a tension spring 26. The tension spring 26 is located between the top stop block 251 of the support rod 25 and the support plate 21. The two ends of the tension spring 26 are fixedly connected to the corresponding stop block 251 and the support plate 21, respectively. Under the tension of the two ends of the tension spring 26, the stop block 251 can be pulled towards the support plate 21. When the pressure plate 24 applies pressure to the paper, as the support plate 21 continues to descend, the tension spring 26 applies a downward pulling force to the baffle and the support rod 25, so that the pressure plate 24 can maintain a continuous pressure force when squeezing the paper, and together with the gravity of the pressure plate 24 itself, it clamps and fixes the paper, so that the paper will not be skewed during processing.

Various modifications and variations can be made to this utility model by those skilled in the art.
