Description

Technical Field

[0001] This utility model relates to the field of cardboard box creasing and grooving technology, and in particular to a cardboard box side creasing and grooving device. Background Technology

[0002] In the modern packaging industry, cardboard boxes are one of the most commonly used packaging containers, consistently ranking first in usage among all types of packaging products. Thanks to their excellent performance and processing capabilities, they have gradually replaced wooden crates and other transport packaging containers, becoming the mainstay of transport packaging. The production process of cardboard boxes is relatively complex, with creasing and slotting being crucial steps.

[0003] In existing technologies, some equipment does not position cartons accurately enough. During the conveyor belt transport of cartons, cartons are prone to shifting, resulting in inaccurate crease and slotting positions, which affects the subsequent processing and use of the cartons. On the other hand, the depth and position of creases are difficult to adjust flexibly according to different carton sizes, reducing the equipment's versatility and processing efficiency. In addition, the structural design of some equipment is not reasonable enough, resulting in poor stability and high maintenance costs during long-term use. Utility Model Content

[0004] The purpose of this invention is to solve the problems of inaccurate positioning and inflexible creasing adjustment in the existing technology, and to propose a carton side creasing and grooving device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a carton side creasing and slotting device, comprising an operating table, a support frame, and a creasing device. The inner wall of the operating table is provided with a conveyor belt. The support frame is fixedly connected to both sides of the upper surface of the operating table. A first motor is fixedly connected to each side of the support frame. A bidirectional lead screw is fixedly connected to the output end of the first motor. The support frames are symmetrically distributed on the upper surface of the operating table. A limit rod is provided between the two sets of support frames. The ends of the limit rods are threadedly connected to the bidirectional lead screws on the two sets of support frames respectively. The creasing device is connected through the bidirectional lead screw.

[0006] An installation block is fixedly connected to the outer surface of the limiting rod, and an electric actuator is fixedly connected to the lower part of the installation block. The telescopic end of the electric actuator is fixedly connected to the limiting block. There are two sets of limiting rods on the outer surface of the bidirectional lead screw, which are symmetrically distributed.

[0007] Furthermore, the indentation device includes a connecting block located in the middle of the outer wall of the bidirectional lead screw and connected through the bidirectional lead screw. A top plate is fixedly connected between the two connecting blocks, and an indentation strip is threadedly connected to the upper surface of the top plate through the outer surface of the transmission mechanism.

[0008] Furthermore, the transmission mechanism includes a second motor fixedly connected to the upper surface of the top plate, a drive wheel fixedly connected to the output end of the second motor, a belt sleeved on the outer surface of the drive wheel, a driven wheel sleeved on the inner wall of the belt away from the drive wheel, screws fixedly connected to both sides of the driven wheel, and two sets of indentation strips threadedly connected to the screws.

[0009] Furthermore, the indentation strip includes a movable block threadedly connected to the outer surface of the screw, a connecting plate fixedly connected to the bottom of the movable block, a slider slidably connected to the outer surface of the connecting plate, an electric telescopic rod fixedly connected to the bottom of the slider, and a pressing strip fixedly connected to the telescopic end of the electric telescopic rod.

[0010] Furthermore, the outer surface of the connecting plate is provided with a connecting groove, and the connecting groove is slidably connected to the slider, and the slider has two sets of connecting plates slidably connected.

[0011] Furthermore, the two ends of the screw are rotatably connected to fixing blocks, which are fixedly connected to the bottom of the top plate.

[0012] Furthermore, a slot is provided at the top of the top plate, and the transmission mechanism is connected through the slot.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the first motor drives the bidirectional lead screw to rotate, causing the limiting rod to move on the bidirectional lead screw. At the same time, the electric push rod pushes the limiting block to accurately position the carton, effectively preventing the carton from shifting during the conveying process, ensuring the accuracy of the indentation and slotting positions, and improving the processing quality of the carton. This solves the problem of inaccurate positioning when the equipment is in use.

[0015] 2. In this utility model, the second motor drives the screw to rotate through the transmission mechanism, causing the crease strip to move on the screw, which can adjust the crease position according to the width of the carton; at the same time, the electric telescopic rod can flexibly control the pressing depth of the pressing strip to meet the crease requirements of different carton sizes, greatly improving the versatility and processing efficiency of the equipment, thus solving the problem of inflexible crease adjustment during equipment use.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a cardboard box side embossing and grooving device, including an operating table 1, a support frame 2 and an embossing device 3.

[0025] The specific setup and function of the support frame 2 and the indentation device 3 will be explained below.

[0026] In this implementation scheme: a conveyor belt 4 is provided on the inner wall of the operating table 1, and a support frame 2 is fixedly connected to both sides of the upper surface of the operating table 1. A first motor 21 is fixedly connected to the side of each support frame 2, and a bidirectional lead screw 22 is fixedly connected to the output end of the first motor 21. The support frames 2 are symmetrically distributed on the upper surface of the operating table 1. A limit rod 23 is provided between the two sets of support frames 2. The ends of the limit rod 23 are threadedly connected to the bidirectional lead screw 22 on the two sets of support frames 2 respectively. The indentation device 3 is connected through the bidirectional lead screw 22.

[0027] A mounting block 231 is fixedly connected to the outer surface of the limiting rod 23, and an electric actuator 232 is fixedly connected to the lower part of the mounting block 231. A limiting block 233 is fixedly connected to the telescopic end of the electric actuator 232. There are two sets of limiting rods 23 on the outer surface of the bidirectional lead screw 22, which are symmetrically distributed.

[0028] The effect achieved by the above components is as follows: the support frame 2 serves as the main support structure of the equipment. The first motor 21 drives the bidirectional lead screw 22 to rotate, causing the limiting rod 23 to move along the lead screw. In conjunction with the electric push rod 232, the limiting block 233 is driven to achieve precise positioning of cartons of different widths, ensuring that the cartons are stably transported on the conveyor belt 4.

[0029] Specifically, the indentation device 3 includes a connecting block 31, which is located in the middle of the outer wall of the bidirectional lead screw 22 and is connected through the bidirectional lead screw 22. A top plate 32 is fixedly connected between the two connecting blocks 31, and an indentation strip 35 is threadedly connected to the upper surface of the top plate 32 through the outer surface of the transmission mechanism 33.

[0030] The effect achieved by the above components is that the connecting block 31 cooperates with the bidirectional lead screw 22, so that the creasing device 3 can move laterally above the operating table 1, making it convenient to adjust the overall creasing position according to the different specifications of the carton.

[0031] Specifically, the transmission mechanism 33 includes a second motor 331 fixedly connected to the upper surface of the top plate 32. The output end of the second motor 331 is fixedly connected to a drive wheel 332. A belt 333 is sleeved on the outer surface of the drive wheel 332. A driven wheel 334 is sleeved on the inner wall of the end of the belt 333 away from the drive wheel 332. Screws 335 are fixedly connected to both sides of the driven wheel 334. Two sets of indentation strips 35 are threadedly connected to the screws 335.

[0032] The effect achieved by the above components is as follows: after the second motor 331 starts, it drives the drive wheel 332 to rotate, and transmits the power to the driven wheel 334 via the belt 333, which in turn drives the screw 335 to rotate. The rotation of the screw 335 causes the crease strips 35 to move horizontally, allowing the operator to precisely adjust the spacing of the crease strips 35 according to the size of the carton, thus meeting diverse crease position requirements.

[0033] Specifically, the indentation strip 35 includes a movable block 351 threadedly connected to the outer surface of the screw 335, a connecting plate 352 fixedly connected to the bottom of the movable block 351, a slider 353 slidably connected to the outer surface of the connecting plate 352, an electric telescopic rod 354 fixedly connected to the bottom of the slider 353, and a pressing strip 355 fixedly connected to the telescopic end of the electric telescopic rod 354.

[0034] The effects achieved by the above components are as follows: the moving block 351 cooperates with the screw 335 to realize the lateral displacement of the crease strip 35; the slider 353 can slide flexibly on the connecting plate 352 to further fine-tune the lateral position of the electric telescopic rod 354 and the pressing strip 355, thereby enhancing the flexibility of the crease operation; the electric telescopic rod 354 precisely controls the pressing distance of the pressing strip 355, thereby accurately adjusting the crease depth and adapting to cartons of different materials and thicknesses.

[0035] Specifically, the outer surface of the connecting plate 352 is provided with a connecting groove 356, which is slidably connected to the slider 353. The slider 353 has two sets of connecting plates 352 slidably connected.

[0036] The effect achieved by the above components is that the connecting groove 356 provides a stable sliding guide for the slider 353, ensuring that the slider 353 maintains a precise trajectory during movement and preventing deviation or shaking.

[0037] Specifically, the two ends of the screw 335 are rotatably connected to fixing blocks, which are fixedly connected to the bottom of the top plate 32.

[0038] The effect achieved by the above components is as follows: the fixing block provides stable support and rotation fulcrum for the screw 335, ensuring that the screw 335 rotates smoothly under the drive of the transmission mechanism 33, avoiding the decrease in the movement accuracy of the indentation strip 35 due to shaking, and ensuring the stability and reliability of the equipment operation.

[0039] Specifically, a slot is provided on the top of the top plate 32, and the transmission mechanism 33 is connected through the slot.

[0040] Working principle: When in use, first place the carton on the conveyor belt 4, start the first motor 21, adjust the bidirectional lead screw 22 on the two side support frames 2 according to the width of the carton, drive the limit rod 23 to move to the appropriate position, and then the electric push rod 232 pushes the limit block 233 to extend, accurately limiting the carton in the middle of the conveyor belt 4, effectively preventing the carton from shifting during the conveying process.

[0041] Next, based on the carton size and creasing requirements, the second motor 331 is started, driving the screw 335 to rotate via the transmission mechanism 33, causing the creasing strip 35 in the creasing device 3 to move horizontally to a predetermined position. Then, the position of the slider 353 on the connecting plate 352 is adjusted, and the electric telescopic rod 354 is controlled to extend and retract, precisely adjusting the height of the pressing strip 355 and the creasing depth. After preparation, the conveyor belt 4 transports the carton to the area below the creasing device 3, and the pressing strip 355 presses down to creasing and slotting the side of the carton. After processing, the conveyor belt 4 delivers the finished carton, achieving an automated and high-precision carton side creasing and slotting process.
