Description

Technical Field

[0001] This utility model relates to the field of creasing and cutting technology for cardboard for packaging boxes, and in particular to a cardboard structure for packaging boxes, a cardboard creasing and cutting device for packaging boxes, and a packaging system. Background Technology

[0002] In the logistics sector, especially e-commerce logistics, the demand for product packaging has increased dramatically due to the massive volume of goods. Cardboard box packaging plays a crucial role in logistics transportation and product protection due to its advantages such as ease of processing and customization, environmental friendliness and recyclability, lightweight design, and low cost. Faced with a wide variety of goods, cardboard boxes of various sizes and shapes are needed to package them. Matching the size of the cardboard box to the packaged items not only saves cardboard but also prevents damage from collisions during transportation, and further reduces shipping costs. The main material for cardboard box packaging is cardboard, and creasing and cutting are among the important processes in making cardboard boxes.

[0003] In a product packaging production line, horizontal and vertical creases need to be pressed into the cardboard for folding, and cut at the required points before folding. Creases along the feeding direction of the cardboard are called vertical creases, and creases perpendicular to the feeding direction are called horizontal creases. In existing product packaging production lines, cardboard boxes typically have a slit cut at both ends of the horizontal crease. This structure causes interference between adjacent flaps at the slit and between the excess material at the cardboard corner and the flaps during folding, resulting in uneven and unattractive boxes. Therefore, improvements to the box structure and the crease-cutting device are necessary. Utility Model Content

[0004] Technical objective: In order to overcome the shortcomings of the existing technology, this utility model provides a cardboard creasing and cutting device for packaging boxes, which can be used in the commodity packaging production line to realize rapid creasing and cutting of cardboard, and the processed cardboard boxes are easy to fold and aesthetically pleasing.

[0005] Technical Solution: To achieve the above objectives, this utility model discloses a cardboard creasing and cutting device, comprising a longitudinal creasing component, a sewing material cutting component, and an ear-shaped material cutting component disposed on the cardboard conveying path. The longitudinal creasing component can press longitudinal creasing marks on the cardboard for cardboard folding. The sewing material cutting component and the ear-shaped material cutting component are used to cut off excess material on the cardboard. The cutting trajectory of the ear-shaped material cutting component is aligned with the creasing trajectory of the longitudinal creasing component in the cardboard feeding direction. The sewing material cutting component cuts a narrow strip-shaped slit on the cardboard perpendicular to the cardboard feeding direction.

[0006] Furthermore, the longitudinal indentation assembly includes an upper indentation roller and a lower indentation roller that can move closer to or further away from each other. The outer peripheral surface of the upper indentation roller is provided with a flange, and the outer peripheral surface of the lower indentation roller is provided with a groove that mates with the flange. The lower indentation roller is driven to rotate by a motor.

[0007] Furthermore, the fabric cutting assembly includes an upper cutting blade and a lower cutting blade that can be brought close together or moved away from each other. The upper cutting blade is in the shape of a long plate, and the lower cutting blade is provided with a long guide opening for the upper cutting blade to pass through.

[0008] Furthermore, one end of the tailor's upper blade is configured as an arc end, one end of the long guide opening is configured as an arc shape that matches the arc end, and the other end of the tailor's upper blade is provided with a guide plate, one end of which extends into the long guide opening.

[0009] Furthermore, the ear fabric cutting assembly includes an upper ear fabric cutting blade and a lower ear fabric cutting blade that can move closer to or further away from each other.

[0010] Furthermore, the ear material cutting assembly also includes a paper pressing assembly, which includes an elastic pressing rod. The upper end of the elastic pressing rod moves up and down synchronously with the ear material cutting blade, and the lower end is connected to a pressing plate for pressing down the ear material.

[0011] Furthermore, it also includes a longitudinal cutting assembly, which includes an upper cutting blade and a lower cutting blade that can move closer to or further away from each other. The lower cutting blade is driven to rotate by a motor, and the upper cutting blade can move horizontally along a cutting slide rail to align the cutting edges of the upper cutting blade and the lower cutting blade.

[0012] Furthermore, the longitudinal creasing assembly, the sewing material cutting assembly, and the earpiece cutting assembly are each arranged in two symmetrical sets, and are moved closer or further away in the direction perpendicular to the paperboard feeding direction by the first driving assembly; the longitudinal cutting assembly is arranged in two symmetrical sets, and is moved closer or further away in the direction perpendicular to the paperboard feeding direction by the second driving assembly.

[0013] A cardboard structure for packaging boxes includes a cardboard body, several wings symmetrically arranged on both sides of the cardboard body, and a tail wing disposed at one end of the cardboard body. The cardboard body has several transverse creases in the width direction and longitudinal creases in the length direction for connecting the cardboard body and the wings. A narrow strip-shaped slit is provided between two adjacent wings, and the end of the slit near the longitudinal crease is arc-shaped. The tail wing is the same width as the cardboard body.

[0014] A packaging system includes a cardboard creasing and cutting device, a feeding system, a transverse creasing system, and a waste collection system. The feeding system feeds cardboard into the transverse creasing system for transverse creasing. After transverse creasing, the cardboard is fed into the creasing and cutting device for longitudinal creasing and cutting of excess material. The cutting excess material falls into the waste collection system for recycling.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a cardboard creasing and cutting device for packaging boxes. By incorporating a sewing material cutting device, a certain folding space is left between the flaps during cardboard folding. Through the cooperation of the sewing material cutting device and the ear material cutting device, the ear material is cut off at the top corner of the cardboard, preventing interference between the flaps and the top corner during folding, resulting in smoother folding and a more aesthetically pleasing finished box. The use of a long, plate-shaped upper cutting knife and a matching long guide opening on the lower cutting knife ensures smooth cutting of the sewing material. The rounded ends of the cuts effectively disperse stress concentrated at the junction of the longitudinal creasing and the cut during folding, preventing cardboard tearing. The presence of a flange on the outer circumference of the upper creasing roller and a groove on the outer circumference of the lower creasing roller that mates with the flange makes the creasing process more stable and prevents deviation.

Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1 To be continued Figure 11 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0019] This utility model discloses a cardboard structure for a packaging box, comprising a cardboard body 1, several symmetrically arranged wings 2 on both sides of the cardboard body 1, and a tail wing 3 at one end of the body 1. The cardboard body 1 has several transverse creases 4 in its width direction and longitudinal creases 5 in its length direction, which connect the cardboard body 1 to the wings 2. A narrow strip-shaped slit 6 is provided between two adjacent wings 2, with the end of the slit 6 near the longitudinal crease 5 being arc-shaped. The tail wing 3 is the same width as the cardboard body 1. In one specific embodiment, four transverse creases 4 are provided, three of which divide the cardboard into four regions, and one connects the cardboard body 1 to the tail wing 3. Wings 2 are correspondingly arranged at both ends of each divided region on the cardboard body 1. When folded, the tail wing 3 overlaps and adheres to the other end of the cardboard body 1, forming the front, back, top, and bottom sides of the box, with the wings 2 at both ends forming the sides of the box. This cardboard structure for the packaging box can be processed by the following packaging system.

[0020] A packaging system includes a feeding device 700, a transverse creasing device 800, and a creasing and cutting device arranged in sequence. A waste collection device 900 is located below the creasing and cutting device. The feeding device 700 conveys cardboard to a cardboard feeding platform, through which the cardboard is fed into the transverse creasing device 800 for transverse creasing and cutting. After completion, the cardboard is fed into the creasing and cutting device through the feeding platform for longitudinal creasing and cutting of excess material. The cutting residue falls into the waste collection device 900 for recycling. After all creasing and cutting are completed, the cardboard enters the packaging box folding system.

[0021] A cardboard creasing and cutting device for packaging boxes is used in a product packaging production line after the transverse creasing process and before the cardboard folding process. It includes a longitudinal creasing component 100, a seam cutting component 200, a flap cutting component 300, and a longitudinal cutting component 400, all disposed on the cardboard conveying path. The longitudinal creasing component 100 can press longitudinal creasing 5 into the cardboard. The seam cutting component 200 is used to cut off excess seam material 8. The seam cutting component 200 cooperates with the flap cutting component 300 to cut off flap material 7 from the cardboard. The longitudinal cutting component 400 cuts off excess material along the longitudinal slit 9 according to the required width. The cutting trajectory of the flap cutting component 300 is aligned with the creasing trajectory of the longitudinal creasing component 100 in the cardboard feeding direction. The seam cutting component 200 cuts a narrow strip-shaped slit 6 in the cardboard perpendicular to the cardboard feeding direction.

[0022] In one embodiment, the longitudinal creasing assembly 100, the sewing material cutting assembly 200, and the earpiece cutting assembly 300 are each arranged in two symmetrical sets, and are moved closer or further apart by the first driving assembly 500 in the direction perpendicular to the paperboard feeding direction; the longitudinal cutting assembly 400 is arranged in two symmetrical sets, and is moved closer or further apart by the second driving assembly 600 in the direction perpendicular to the paperboard feeding direction. This design allows for symmetrical creasing and cutting of the paperboard, improving processing efficiency.

[0023] Specifically, the first drive assembly 500 includes a mounting bracket 510, a linear guide rail 520, and a drive assembly 530. Two mounting brackets 510 are provided, which, driven by the drive assembly 530, move laterally closer to or further away from the two linear guide rails 520. The drive assembly 530 includes a motor and a transmission belt driven by the motor; this driving method is existing technology and will not be described further. Two sets of longitudinal indentation assemblies 100, sewing material cutting assemblies 200, and earpiece cutting assemblies 300 are symmetrically mounted on the two mounting brackets 510, moving closer to or further away with the two mounting brackets 510. The second drive assembly 600 is configured in the same way as the first drive assembly 500, and the two sets of longitudinal cutting assemblies 400 also move closer to or further away in the same manner, which will not be described further.

[0024] The longitudinal indentation assembly 100 includes an upper indentation roller 110 and a lower indentation roller 120 that can move closer to or further away from each other. The outer circumferential surface of the upper indentation roller 110 is provided with a flange 111, and the outer circumferential surface of the lower indentation roller 120 is provided with a groove 121 that mates with the flange 111. The lower indentation roller 120 is driven to rotate by a motor. Specifically, the upper indentation roller 110 is mounted at the output end of an adjusting cylinder 130, and the movement of the cylinder allows it to move closer to or further away from the lower indentation roller 120.

[0025] The fabric cutting assembly 200 includes an upper cutting blade 210 and a lower cutting blade 220 that can move closer to or further apart from each other. The upper cutting blade 210 is a long plate with a certain thickness, which is selected according to the width of the slit 6. The lower cutting blade 220 is provided with a long guide opening 221 for the upper cutting blade 210 to pass through. One end of the upper cutting blade 210 is set as an arc end 211, and one end of the long guide opening 221 is set as an arc shape to cooperate with the arc end 211. This design is used to cut an arc shape at one end of the slit 6. The other end of the upper cutting blade 210 is provided with a guide plate 212. One end of the guide plate 212 extends into the long guide opening 221. When the upper cutting blade 210 approaches the lower cutting blade 220, the guide plate 212 acts as a leading part, which can ensure the rapid alignment of the upper cutting blade 210 and the long guide opening 221 in the initial insertion stage, avoiding deflection or jamming caused by excessive blade length. In a specific embodiment, such as Figure 5 As shown, the upper tailor blade 210 has a right-angled trapezoidal cross-section, with its hypotenuse facing the long guide opening 221. Specifically, the upper tailor blade 210 is installed at the output end of the adjusting cylinder 230. The cylinder's extension and retraction drive the upper tailor blade 210 to rise and fall along the tailor slide rail 240, thereby allowing it to move closer to and further away from the lower tailor blade 220. The cut fabric 8 falls into the waste collection box or waste collection conveyor belt below the machine frame.

[0026] The ear-shaped material cutting assembly 300 includes an upper ear-shaped material cutting blade 310, a lower ear-shaped material cutting blade 320, and a paper pressing assembly 330, which can move closer to or further away from each other. The paper pressing assembly 330 includes an elastic pressure rod 331. The upper end of the elastic pressure rod 331 moves up and down synchronously with the upper ear-shaped material cutting blade 310, and the lower end is connected to a pressure plate 332 for pressing down the ear-shaped material. Specifically, the upper ends of the upper ear-shaped material cutting blade 310 and the elastic pressure rod 331 are connected to the output end of the adjusting cylinder 350 through a connecting plate 340. By extending and retracting the cylinder, the upper ear-shaped material cutting blade 310 and the elastic pressure rod 331 are driven to move up and down. When the elastic pressure rod 331 descends, it causes the pressure plate 332 to descend and press the ear-shaped material onto the frame. At the same time, the upper ear-shaped material cutting blade 310 and the lower ear-shaped material cutting blade 320 move closer to cut the ear-shaped material. After cutting, the adjusting cylinder 350 retracts, and the pressure plate 332 rises to release the material. The material falls into the waste collection box or waste collection conveyor belt below the frame. The elastic pressure rod 331 is equipped with a spring for cushioning and shock absorption.

[0027] The longitudinal cutting assembly 400 includes an upper slitting blade 410 and a lower slitting blade 420 that can move closer to or further away from each other. The lower slitting blade 420 is driven to rotate by a motor. The upper slitting blade 410 is connected to a pneumatic device that can drive it to move closer to or further away from the lower slitting blade 420. The upper slitting blade 410 can move horizontally along the slitting slide rail 430 to align the blades of the upper slitting blade 410 with those of the lower slitting blade 420.

[0028] like Figure 1 and Figure 8 As shown in the diagram, the arrows indicate the direction of cardboard feeding. The cardboard passes between the upper and lower cutters or between the upper and lower rollers, and each component completes the creasing or cutting action in sequence as needed.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
