Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, specifically to a cardboard box production edge cutting device. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc. The production of cardboard boxes involves die-cutting the cardboard into the unfolded shape of the cardboard box, then pressing corresponding creases at the bending points of the cardboard box, and finally folding the cardboard box into a cardboard box by pressing the creases. Before folding the cardboard box into a cardboard box, the cardboard box also needs to be trimmed to remove excess waste material.

[0003] A search revealed that Chinese patent application CN219634637U discloses a trimming device for carton production. By setting a limiting component, the carton is pre-placed on a support platform, with the sides of the support platform requiring trimming positioned outside the limiting plate. An electric push rod then drives the support frame, which in turn pushes the limiting frame to slide synchronously on a guide rail. The upper end of the limiting frame approaches the edge of the carton until both sets of limiting frames abut against the sides of the carton requiring trimming, thus limiting the sides of the carton. Then, a cylinder drives the limiting plate downwards, clamping the carton between the limiting plate and the support platform, thus limiting the carton and facilitating trimming.

[0004] However, the following technical problems still exist when implementing the above technical solution: operators need to manually clamp the cardboard. This manual operation not only increases the labor intensity of operators and reduces production efficiency, but also makes it difficult to guarantee the accuracy and stability of manual clamping, which can easily affect the edge trimming effect of the carton. In addition, since different batches of cardboard may have differences in thickness, the device lacks the ability to adapt to the thickness of the cardboard and cannot effectively limit the processing of cardboard with different thicknesses.

[0005] Therefore, providing a cardboard production edge-cutting device that can automatically clamp cardboard and limit the processing of cardboard of different thicknesses during use, thereby improving the production efficiency and finished product quality of cardboard boxes, is a problem that this utility model urgently needs to solve.

The fixed frame is also equipped with multiple sets of movable rollers that can move in the vertical direction. The drive roller and the movable roller are connected by a transmission belt whose surface is in contact with the surface of the cardboard box.

[0014] Preferably, the movable roller is mounted in the fixed frame in a way that allows it to be raised and lowered via a sliding member, and the fixed frame is provided with a compensation component that adjusts the tension of the transmission belt when the movable roller is raised and lowered.

[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0034] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0035] Reference Figures 1-6As shown, a carton production edge-cutting device includes: a belt conveyor 100 and a mounting frame 101 fixedly mounted on the upper surface of the belt conveyor 100. The mounting frame 101 is provided with a liftable cutting head 104 for edge cutting. The feeding end of the belt conveyor 100 is fixedly provided with two sets of opposing and adjustable spacing limiting mechanisms 300 for limiting the carton. The upper surface of the belt conveyor 100, located in front of the mounting frame 101, is fixedly provided with a height-adjustable fixing mechanism 400 for fixedly conveying cartons of different thicknesses vertically.

[0036] In use, cartons are fed into the belt conveyor 100 from the inlet. The distance between the two sets of opposing limiting mechanisms 300 is adjusted to prevent lateral shifting during transport. The cartons are conveyed forward on the belt conveyor 100. When passing the height-adjustable fixing mechanism 400, this mechanism adjusts according to the carton's thickness to ensure stable transport before cutting. When the carton reaches a position below the cutting head 104, the cutting head 104 descends to trim the edges. After cutting, the carton continues to be conveyed forward and exits from the outlet of the belt conveyor 100. The coordinated use of the limiting mechanism 300 and the fixing mechanism 400 ensures stability during cutting, thereby improving trimming accuracy. The adjustable distance of the limiting mechanism 300 and the adjustable height of the fixing mechanism 400 allow the device to adapt to cartons of different sizes and thicknesses, improving its versatility and flexibility.

[0037] Reference Figure 3 As shown, the limiting mechanism 300 includes: a sliding rod 302, a first spring 303, and a baffle 304; wherein, a fixed plate 301 is fixedly provided on the upper surface of the belt conveyor 100, and a plurality of sliding rods 302 are slidably passed through the fixed plate 301 at intervals, a baffle 304 is fixedly provided at one end of the sliding rod 302, the bottom surface of which is slidably engaged with the upper surface of the belt conveyor 100, and an anti-detachment plate 306 is fixedly provided at the other end of the sliding rod 302, and a first spring 303 is also sleeved on the sliding rod 302, with both ends abutting against the side of the fixed plate 301 and the side of the baffle 304 respectively.

[0038] In the above scheme, the sliding position of the sliding rod 302 in the fixed plate 301 is adjusted by the first spring 303 according to the width of the carton, thereby changing the distance between the baffle 304 and the upper surface of the belt conveyor 100, thus limiting the carton. At the same time, when the carton contacts the baffle 304, the first spring 303 plays a buffering role to prevent the carton from being damaged due to collision.

[0039] Reference Figure 3 As shown, the baffle 304 is provided with multiple sets of rotating rollers 305 whose surfaces contact the edge of the cardboard box at intervals.

[0040] In the above scheme, the carton is conveyed forward on the belt conveyor 100. When the edge of the carton contacts the rotating roller 305 inside the baffle 304, the rotating roller 305 begins to rotate. The rotating roller 305 contacts and rolls with the edge of the carton, reducing the friction between the carton and the baffle 304, making the carton smoother during the conveying process. While rolling, the rotating roller 305 also plays a role in limiting and guiding the carton, ensuring that the carton does not deviate from the predetermined path during the conveying process. The rolling of the rotating roller 305 reduces the direct contact between the carton and the baffle 304, thereby reducing frictional resistance and making the carton more stable during the conveying process.

[0041] Reference Figures 4-5 As shown, the fixing mechanism 400 includes: a fixed frame 401, a drive roller 402, a movable roller 403, and a transmission belt 407; wherein, the fixed frame 401 is fixedly provided on the upper surface of the belt conveyor 100, and the fixed frame 401 is driven by a drive motor 406 to provide a rotatable drive roller 402, and the fixed frame 401 is also provided with multiple sets of movable rollers 403 that can move in the vertical direction. The drive roller 402 and the movable roller 403 are connected by a transmission belt 407 whose surface is in contact with the surface of the cardboard box.

[0042] In the above scheme, the carton is conveyed forward on the belt conveyor 100. When the carton reaches the position of the fixing mechanism 400, the upper and lower surfaces of the carton contact the transmission belt 407 and the movable roller 403 respectively. The drive motor 406 starts, driving the drive roller 402 to rotate, which in turn drives the movable roller 403 to rotate through the transmission belt 407. The transmission belt 407 is in close contact with the surface of the carton, and the friction force drives the carton forward. At the same time, the movable roller 403 is adjusted up and down according to the thickness of the carton to ensure that the transmission belt 407 always maintains contact with the surface of the carton. During the conveying process, the combined use of the transmission belt 407 and the movable roller 403 plays a role in fixing the carton and preventing the carton from moving or deforming during the cutting process.

[0043] Reference Figure 5 As shown, the movable roller 403 is mounted in the fixed frame 401 in a height-adjustable manner via a sliding member, and the fixed frame 401 is provided with a compensation component 500 for adjusting the tension of the transmission belt 407 when the movable roller 403 is raised or lowered.

[0044] When cartons of varying thicknesses enter the fixing mechanism 400, the movable roller 403 automatically rises and falls according to the carton's thickness to maintain close contact between the transmission belt 407 and the carton surface. The movable roller 403 moves within the fixing frame 401 via a sliding component to adapt to changes in carton thickness. The sliding component design ensures smooth and controllable rising and falling of the movable roller 403. As the movable roller 403 rises and falls, the compensation component 500 automatically adjusts the tension of the transmission belt 407 to ensure it maintains appropriate tension, thus maintaining stable conveying performance. Under the adjustment of the compensation component 500, the transmission belt 407 and the movable roller 403 work together to stably fix and convey the carton forward. Through the rising and falling of the movable roller 403 and the adjustment of the compensation component 500, this device can adapt to cartons of different thicknesses, improving its versatility and flexibility. The compensation component 500 automatically adjusts the tension of the transmission belt 407, ensuring the stability and accuracy of the carton during conveying.

[0045] Reference Figure 4 As shown, the sliding member includes: a second spring 405; the inner side wall of the fixed frame 401 is provided with a sliding groove 404, the movable roller 403 is slidably disposed in the sliding groove 404 by a slider, and the second spring 405 is fixedly disposed in the sliding groove 404, one end of the second spring 405 is abutting against the slider.

[0046] In the above scheme, the movable roller 403 is slidably mounted in the groove 404 of the fixed frame 401 via a slider. Initially, the second spring 405 is compressed, providing a certain preload to the slider. When the carton enters the fixed mechanism 400, the change in carton thickness causes the movable roller 403 to be subjected to different degrees of pressure. Depending on the change in carton thickness, the movable roller 403 will rise and fall within the groove 404. When the carton is thicker, the movable roller 403 will descend; when the carton is thinner, the movable roller 403 will rise. The second spring 405 plays a buffering and resetting role during the rising and falling of the movable roller 403. When the movable roller 403 descends, the second spring 405 is further compressed; when the movable roller 403 rises, the second spring 405 gradually returns to its original state, pushing the movable roller 403 back to its initial position or close to its initial position. As the movable roller 403 rises and falls, the tension of the transmission belt 407 will change. At this time, the compensation component 500 will make corresponding adjustments according to the tension change of the transmission belt 407 in order to maintain the tension of the transmission belt 407 stable.

[0047] Reference Figure 6As shown, the compensation component 500 is provided in two sets located on both sides of the drive roller 402. The compensation component 500 includes: a rotating plate 501, a support roller 502 and a third spring 503; wherein, the rotating plate 501 is rotatably disposed on the inner side wall of the fixed frame 401, and one end of the rotating plate 501 is rotatably provided with a support roller 502 in contact with the transmission belt 407, and a third spring 503 is fixedly disposed between the two sets of rotating plates 501.

[0048] In the above scheme, the tension of the transmission belt 407 changes as the movable roller 403 rises and falls. When the movable roller 403 descends, the portion of the transmission belt 407 between the drive roller 402 and the movable roller 403 becomes slack; when the movable roller 403 rises, this portion becomes taut. The change in tension of the transmission belt 407 drives the support roller 502 and the rotating plate 501 on which it is located to rotate. When the transmission belt 407 is slack, the support roller 502 rotates with the rotating plate 501 in the slack direction, increasing the support force on the transmission belt 407; when the transmission belt 407 is taut, the support roller 502 rotates with the rotating plate 501 in the opposite direction, reducing the additional pressure on the transmission belt 407. The spring 503 is connected between the two sets of rotating plates 501, serving to adjust and balance the rotation angle of the two sets of rotating plates 501. When one side of the rotating plate 501 rotates, the third spring 503 will stretch or compress, pushing the other side of the rotating plate 501 to rotate in the opposite direction, thereby maintaining the tension balance of the transmission belt 407 on both sides. Through the coordinated use of the rotating plate 501, the support roller 502 and the third spring 503, the tension of the transmission belt 407 is stably adjusted, ensuring the stability and accuracy of the carton during the conveying process.

[0049] Reference Figures 1-2 As shown, the trimming device further includes a recycling component 200 disposed at the discharge end of the belt conveyor 100 to collect the waste material after trimming; wherein, the recycling component 200 includes a guide plate 201 and a collection box 202; the guide plate 201 is fixedly disposed at the discharge end of the belt conveyor 100 and is inclined, and the collection box 202 for collecting waste material is movably disposed at the lower end of the guide plate 201.

[0050] In the above scheme, after the carton is cut by the cutting head 104 on the belt conveyor 100, waste material is generated. The waste material after cutting is guided to the discharge end of the belt conveyor 100 and slides down along the inclined guide plate 201. Under the guidance of the guide plate 201, the waste material falls into the collection box 202, realizing the centralized collection of waste material. When the waste material in the collection box 202 accumulates to a certain amount, the collection box 202 can be easily removed for cleaning or replacement.

[0051] Reference Figures 1-2As shown, the cutting head 104 is mounted in the mounting frame 101 in a height-adjustable manner via a lifting component. The lifting component includes a hydraulic rod 102 and a limiting rod 103. The hydraulic rod 102 is fixedly mounted on the mounting frame 101. The output end of the hydraulic rod 102 is vertically downward and the cutting head 104 is fixedly mounted thereon. Multiple sets of limiting rods 103 are slidably mounted on the mounting frame 101 at intervals. The cutting head 104 is fixedly mounted on the bottom surface of the limiting rod 103.

[0052] In the initial state of the carton production edge-cutting device, the cutting head 104 is stably suspended at a certain height within the mounting frame 101 through the cooperation of the hydraulic rod 102 and the limiting rod 103. At this time, the hydraulic rod 102 is in a retracted state, while the limiting rod 103 provides stable support for the cutting head 104. When the carton is conveyed forward on the belt conveyor 100 and reaches directly below the cutting head 104, the control system issues a command to activate the hydraulic rod 102. Upon receiving the command, the hydraulic rod 102 begins to extend, pushing the cutting head 104 downward. Simultaneously, the limiting rod 103 slides on the mounting frame 101, providing stable guidance and support for the cutting head 104. As the hydraulic rod 102 extends, the cutting head 104 gradually approaches and contacts the edge of the carton. When the cutting head 104 contacts the edge of the carton, it begins to work, performing edge-cutting operations on the carton. During the cutting process, the hydraulic rod 102 maintains a stable elongated state, while the limiting rod 103 ensures the stable movement of the cutting head 104 in the vertical direction.

[0053] In summary, the cardboard box production edge-cutting device provided by this utility model allows the cardboard box to be placed at the feed end of the belt conveyor 100 during use. Two sets of opposing and adjustable-spaced limiting mechanisms 300 limit the cardboard box, ensuring that it does not shift during transport. The limiting mechanism 300 is implemented by a sliding rod 302, a first spring 303, and a baffle 304. The sliding rod 302 slides within a fixed plate 301, and the baffle 304 adjusts its position according to the width of the cardboard box and maintains contact with the edge of the cardboard box through the first spring 303. Simultaneously, the rotating roller 305 within the baffle 304 reduces friction with the cardboard box. The cardboard box is conveyed forward on the belt conveyor 100 to the fixing mechanism 400 in front of the mounting frame 101. The fixing mechanism 400 includes a fixed frame 401, a drive roller 402, a movable roller 403, and a transmission belt 407. The drive motor 406 drives the drive roller 402 to rotate, which in turn drives the cardboard box forward through the transmission belt 407. The movable roller 403 moves up and down within the fixed frame 401 according to the thickness of the carton, maintaining contact with the carton through a sliding component to ensure stable carton transport. When the carton is transported to the appropriate position below the mounting frame 101, the cutting head 104 starts working. The cutting head 104 moves up and down within the mounting frame 101 via a hydraulic rod 102 and a limiting rod 103, adjusting the cutting position according to the height of the carton. The hydraulic rod 102 drives the cutting head 104 to descend, trimming the carton. During the lifting and lowering of the movable roller 403, the compensation component 500 adjusts the tension of the transmission belt 407 to ensure that the transmission belt 407 always maintains appropriate tension and does not affect the carton transport. The trimmed carton continues to be transported forward to the discharge end of the belt conveyor 100. The discharge end is equipped with a recycling component 200, including a guide plate 201 and a collection box 202. The guide plate 201 is inclined to guide the waste generated by trimming into the collection box 202 for collection.
