Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, and in particular to a crimping device for cardboard box production. Background Technology

[0002] In the corrugated box manufacturing industry, the performance of the creasing device directly affects the forming quality and production efficiency of the corrugated boxes. With the booming development of the packaging industry, corrugated boxes, as one of the most widely used packaging materials, have seen a continuous increase in market demand, placing higher demands on corrugated box production technology. Traditional creasing devices used in corrugated box production have revealed many problems in practical applications. Regarding environmental factors, dry seasons accelerate the evaporation of moisture inside the cardboard, making it prone to bursting during the creasing process. This not only significantly increases the amount of cardboard scrapped during creasing, causing substantial waste of cardboard raw materials and increasing production costs, but also prolongs the service life of the creasing device, slowing down the creasing process and severely reducing work efficiency. In terms of operation, the previous cardboard creasing process mostly relied on manual fixing, which significantly increased the number of times workers came into contact with the machinery, greatly increasing the risk of accidents. Moreover, when manually holding the cardboard for creasing, the cardboard is prone to displacement, leading to uneven and inconsistent creasing, seriously affecting the quality of the cardboard creasing.

[0003] After prolonged use, the pressing rollers of traditional equipment tend to wear down and become dull, which greatly reduces the pressing effect and results in shallow pressing marks. This leads to deviations during subsequent folding processes, producing a large number of defective products and causing economic losses to enterprises. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-5This utility model discloses a creasing device for carton production, comprising: a support plate 1 and auxiliary components. Two abutment plates 4 are arranged between the two support plates 1, which allows the abutment plates 4 to function within the space defined by the support plates 1, providing basic support for the installation and functional realization of subsequent components. A positioning block 16 is fixedly connected to the abutment plate 4 through the cooperation of a first screw 14 and a first adjusting nut 15. The first screw 14 and the first adjusting nut 15 cooperate to fix and adjust the position of the positioning block 16, thereby adjusting the position of the positioning block 16 on the abutment plate 4 according to actual needs. The outer surface of the positioning block 16 has a first adjusting groove 17 on both the upper and lower sides. The first adjusting groove 17 provides installation space for the first limiting post 18 to be installed laterally, and provides guidance and range of motion for the rotation adjustment of the first connecting rod 19. The inner surface of the first adjusting groove 17 is fixedly connected to the first limiting post 18, which is fixed in the first adjusting groove 17 and serves to limit the rotation angle and position of the first connecting rod 19. To ensure the stability and accuracy of its rotation, a first connecting rod 19 is rotatably connected to the outer surface of the first limiting post 18. The first connecting rod 19 can rotate around the first limiting post 18, and its rotation enables linkage with other components to adapt to different working requirements. The front and rear sides of the outer surface of the first connecting rod 19 away from the first limiting post 18 are fixedly connected to the second limiting post 20. The second limiting post 20 is fixed on the first connecting rod 19 and is used to limit the elastic pressure ring 5 to maintain its correct position during operation. The outer surface of the second limiting post 20 abuts against the elastic pressure ring 5. The elastic pressure ring 5 abuts against the outer surface of the second limiting post 20 and applies pressure to the carton using its own elasticity to achieve stable pressure during the creasing process. The contact plate 4 is fixedly connected to the high-performance return spring 8 through the cooperation of the second adjusting nut 22 and the second screw 23. The second adjusting nut 22 and the second screw 23 cooperate to achieve the fixed connection between the high-performance return spring 8 and the contact plate 4, and at the same time, the compression degree of the spring can be adjusted to control the spring force.

[0025] The second limiting posts 20 are symmetrically arranged on the front and rear sides of the outer surface of the first connecting rod 19. This symmetrical arrangement ensures the balanced force on the first connecting rod 19, making the pressure distribution of the elastic pressure ring 5 uniform during operation. The second limiting posts 20 are symmetrically arranged on the left and right sides of the inner walls of the two second connecting rods 21. This arrangement allows the second limiting posts 20 to cooperate with both the first connecting rod 19 and the second connecting rod 21 simultaneously, achieving stable connection and coordinated operation between the components. The positioning block 16 and the first screw 14 are slidably connected. The sliding connection between the positioning block 16 and the first screw 14 makes the positioning block... Positioning blocks 16 can move on the first screw 14, facilitating position adjustment according to work requirements. The positioning blocks 16 are symmetrically arranged on the left and right sides of the outer surface of the first screw 14. This symmetrical arrangement ensures the balance of forces on the first screw 14 and improves the stability of the entire structure. The positioning blocks 16 abut against the inner wall of the contact plate 4, further fixing their position and preventing displacement during operation. Two first adjusting nuts 15 are symmetrically arranged on the outer walls of the two contact plates 4. This symmetrical arrangement of the first adjusting nuts 15 facilitates simultaneous adjustment of the two contact plates. The positioning blocks 16 on each contact plate 4 are adjusted to ensure consistent adjustment. The number of positioning blocks 16 corresponds to the number of first screws 14, ensuring that each first screw 14 can cooperate with the corresponding positioning block 16 for precise adjustment and fixation. The first screws 14 are arranged in a circumferential array between the two contact plates 4. This circumferential array makes the distribution of positioning blocks 16 on the contact plates 4 more uniform, resulting in a more balanced force distribution on the entire structure. The second screw 23 is staggered with the first screw 14, which avoids the second screw 23... The interference with the first screw 14 in space makes the installation layout of the high-performance return spring 8 and the positioning block 16 more reasonable. Both ends of the high-performance return spring 8 abut against the contact plate 4. The high-performance return spring 8 abuts against the contact plate 4. During operation, the spring force provides the return power to the contact plate 4, ensuring the continuous and stable operation of the device. The position of the second adjusting nut 22 is the same as the position of the first adjusting nut 15. The same position setting facilitates operation and adjustment, making the adjustment of the high-performance return spring 8 and the positioning block 16 more convenient and quick.

A controller 7 is fixedly connected to the side wall of the support plate 1. The controller 7 is fixed to the side wall of the support plate 1 and is used to control the operation of each component of the entire creasing device to achieve automated operation and precise control. Guide motors 6 are fixedly connected to the outer walls of both support plates 1. The guide motors 6 provide power to the guide rotating column 13, driving it to rotate and thus guiding the carton. The output end of the guide motor 6 is fixedly connected to the guide rotating column 13, which is connected to the output end of the guide motor 6 to transmit the motor's power, driving the subsequent components to move and complete the carton guiding work. An adjusting rod 12 is fixedly connected to one end of the guide rotating column 13. The adjusting rod 12 is connected to the guide rotating column 13 and, through its own structural characteristics, can adjust the guide... The position and angle of the guide roller 10 are adjusted. An adjusting column 11 is fixedly connected to the side wall of the adjusting rod 12. The adjusting column 11 is fixed to the side wall of the adjusting rod 12, providing mounting support for the guide roller 10 and adjusting the guide roller 10 under the drive of the adjusting rod 12. The guide roller 10 is rotatably connected to the outer surface of the adjusting column 11, allowing the guide roller 10 to rotate around the adjusting column 11. During the guiding process, it cooperates with the guide plate 9 to guide and transport the carton. The outer surface of the guide roller 10 abuts against the guide plate 9, which in turn abuts against the guide roller 10, limiting and guiding the guide roller 10 to ensure that the carton moves along the correct path during transport. The crease-pressing rotating column 3 is located between two support plates 1. The crease-pressing rotating column 3 operates within the space defined by the support plates 1, adjusting the... The carton undergoes a creasing operation, and its position ensures smooth creasing. The guide rotating column 13 is located on the inner wall of the support plate 1. Driven by the guide motor 6, the guide rotating column 13 guides the carton. Its position facilitates cooperation with other components to achieve the guiding function. Guide plates 9 are symmetrically arranged on the front and rear sides of the inner wall of the support plate 1. The symmetrical arrangement of the guide plates 9 ensures the stability and symmetry of the carton during transport, preventing the carton from shifting. The number of guide rollers 10 corresponds to the number of guide plates 9, ensuring that each guide plate 9 can cooperate with the corresponding guide roller 10, ensuring effective guidance and support for the carton during transport. An array of contact plates 4 is arranged on the outer surface of the creasing rotating column 3.An array of contact plates 4 is arranged on the outer surface of the crease-rotating column 3, increasing the contact area with the carton and making the crease-forming process more uniform and stable. The number of contact plates 4 corresponds to the number of crease-rotating columns 3, ensuring that each crease-rotating column 3 can cooperate with the corresponding contact plate 4, achieving efficient crease-forming.

[0027] Working Principle: When using this creasing device for carton production, the equipment is first started via controller 7. The guide motor 6 begins to run, driving the guide rotating column 13 to rotate. This, in turn, causes the adjusting rod 12 connected to one end of the guide rotating column 13 to rotate. The adjusting rod 12 drives the adjusting column 11 to adjust the position and angle of the guide roller 10, ensuring proper alignment between the guide roller 10 and the guide plate 9. The carton to be creasing is then placed on the guide roller 10. Driven by the guide motor 6, the guide roller 10, under the limiting and guiding action of the guide plate 9, smoothly conveys the carton to the creasing area. Once the carton reaches the creasing area, the creasing motor 2 starts, driving the creasing rotating column 3 to rotate. Since the contact plates 4 are arrayed on the outer surface of the creasing rotating column 3 in corresponding quantities, the contact plates 4 rotate with the creasing rotating column 3. The positioning block 16 contacts the carton. Simultaneously, the position of the positioning block 16 can be pre-adjusted by the first screw 14 and the first adjusting nut 15, so that the first connecting rod 19, the second limiting post 20, and the elastic pressure ring 5 connected to the positioning block 16 are in the appropriate position. The elastic pressure ring 5 applies pressure to the carton using its own elasticity, and completes the creasing operation of the carton in conjunction with the creasing rotating post 3. During the creasing process, the high-performance reset spring 8 is fixed to the contact plate 4 by the second adjusting nut 22 and the second screw 23. The spring force provides reset power to the contact plate 4, ensuring that the contact plate 4 can be reset in time after each creasing operation, ensuring the continuous and stable operation of the device. After the carton is creasing, the creasing carton is conveyed out of the device with the cooperation of the guide roller 10 and the guide plate 9, completing one creasing process.
