Description

Technical Field

[0001] This utility model belongs to the field of corrugated paper technology, and in particular relates to a corrugated cardboard cutting device. Background Technology

[0002] In the prior art, a search revealed a Chinese patent that discloses "a corrugated cardboard cutting device" with the publication number "CN208880884U". This patent mainly includes an operating table, a fixing strip, and a support column. The support column is vertically welded to one edge of the top of the operating table. The top of the operating table, except for the edge near the support column, is inlaid with a fixing strip. A bearing is rotatably connected to the top center of the support column. A movable arm is sleeved on the outside of the bearing. A limit rod is welded to the top of one end of the movable arm.

[0003] Existing corrugated cardboard cutting equipment lacks an effective centering and positioning mechanism during operation. When moving and cutting corrugated cardboard, the cardboard is prone to shifting, which can lead to problems such as dimensional errors and uneven edges, thus affecting the quality of the finished product and subsequent processing. Utility Model Content

[0004] The purpose of this utility model is to provide a corrugated cardboard cutting device. By setting a positioning part, it solves the problem that the cardboard is prone to displacement when moving and cutting corrugated cardboard due to the lack of an effective centering positioning mechanism. This leads to problems such as dimensional errors and uneven edges, which in turn affect the quality of the finished product and subsequent processing.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a corrugated cardboard cutting device, comprising a support frame, a conveying unit mounted on the support frame for conveying corrugated paper, a positioning unit mounted on the support frame for positioning the conveyed corrugated paper to prevent it from shifting during conveying and affecting cutting, and a cutting unit mounted on the support frame for cutting the corrugated paper. After the corrugated paper is placed in the conveying unit, the positioning unit is immediately activated to position it, preventing the corrugated paper from shifting during conveying and affecting cutting. After the positioning unit completes positioning the corrugated paper, the conveying unit can convey the corrugated paper to the cutting unit for segmentation, while simultaneously treating the dust generated during the cutting process.

[0007] Furthermore, the conveying unit includes a slitting conveyor belt mounted on a support frame, on which corrugated paper is mounted; wherein the slitting conveyor belt can transport the corrugated paper to the cutting unit for cutting.

[0008] Furthermore, the positioning unit includes a positioning assembly, which is mounted on a support frame and used to position the corrugated paper during conveying. The positioning assembly includes L-shaped plates fixedly connected to both sides of the conveying unit. Two slide rods are fixedly connected to the side of the two L-shaped plates that are close to each other. Two sliders are slidably connected to the outer walls of the two slide rods. Guide roller clamps are fixedly connected to the bottom of each of the two sliders. Both guide roller clamps are in contact with the corrugated paper. During the positioning process of the corrugated paper, the guide rollers equipped with the guide roller clamps can reduce the friction on the corrugated paper during positioning, ensuring that the corrugated paper can still move with the slitting conveyor belt after positioning is completed.

[0009] Furthermore, a drive assembly, mounted on the positioning assembly, provides power to the positioning assembly. Upon activation, the drive assembly drives the positioning assembly to position the corrugated paper on the slitting conveyor belt, preventing displacement during movement. The drive assembly includes a rectangular plate sleeved on the outer wall of two slide rods. A fixing block is fixedly connected to the top of the rectangular plate, and a hydraulic push rod is mounted on the fixing block. A track is fixedly connected to the top of the rectangular plate, and a slider is slidably connected to the outer surface of the track. A connecting member is provided on the slider. The output end of the hydraulic push rod is fixedly connected to the slider. The connecting member includes two connecting rods hinged to the top of the slider, with the ends of the two connecting rods away from the slider being hinged to the two sliders. When the slider moves, the two connecting rods drive the slider connected to it, causing the guide roller clamps on the slider to move closer together, thereby positioning the corrugated paper.

[0010] Furthermore, the cutting section includes a cutting assembly, which is mounted on a support frame and used to cut corrugated paper. The cutting assembly includes two fixed blocks 2 fixedly connected to the top of the support frame. A motor is fixedly connected to the left fixed block 2. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. Several cutting discs are sleeved on the outer wall of the rotating shaft. The several cutting discs are all adapted to the slitting conveyor belt. The rotating shaft passes through the two fixed blocks 2 and is rotatably connected to the two fixed blocks 2.

[0011] Furthermore, a dust collection component, mounted on a support frame, is used to handle paper scraps generated during the cutting process of the cutting component. The cutting component and the dust collection component work together; after the cutting component completes the cutting of the corrugated paper, the dust collection component can handle the dust generated during cutting. The dust collection component includes a dust collection hood fixedly connected to the top of the support frame. A vacuum cleaner is mounted on the support frame, and a connecting pipe is fixedly connected to the right side of the vacuum cleaner. The end of the connecting pipe is fixedly connected to the dust collection hood. Each dust collection hood is adapted to several cutting discs and can handle the dust generated when the cutting discs cut the corrugated paper.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a positioning unit, during use, the corrugated paper is first placed in the middle of the slitting conveyor belt. Then, the hydraulic pusher is activated, which pushes the second slider to slide linearly along the track. Since the top of the second slider is connected to two symmetrically distributed connecting rods through a hinge shaft, and the other end of the connecting rod is respectively hinged to the first slider sliding on the slide rod, a four-bar linkage mechanism is formed. As the hydraulic pusher continues to push, the second slider drives the two first sliders to slide towards each other on the slide rod through the connecting rod. The guide roller clamps installed at the bottom of the first sliders also move closer to each other, clamping and positioning the corrugated paper on both sides of the slitting conveyor belt. The guide roller clamps are equipped with freely rotating guide rollers, which can effectively reduce the friction with the surface of the corrugated paper during positioning. Even if the corrugated paper is positioned, it can still be smoothly conveyed forward under the drive of the slitting conveyor belt, ensuring the smooth progress of subsequent slitting processes. This design not only achieves precise positioning of the corrugated paper, but also ensures the integrity and continuity of material conveying, significantly improving the production efficiency of the equipment.

[0014] 2. By setting up a cutting section, after the positioned corrugated paper is conveyed to the designated workstation of the cutting section by the slitting conveyor belt, the operator starts the motor. The motor drives the rotating shaft to rotate, which drives multiple evenly distributed cutting discs on the rotating shaft to synchronously cut the corrugated paper in a circular motion. Due to the high-speed friction between the sharp cutting edge of the cutting disc and the surface of the corrugated paper, a large amount of flying paper scraps will be generated during the cutting process. In order to keep the working environment clean and avoid paper scraps affecting the operation of the equipment, the vacuum cleaner can be started at the same time. After the vacuum cleaner is started, a negative pressure environment is formed inside the equipment. The negative pressure is conducted to the dust hood through the connecting pipe, which generates a strong suction at the opening of the dust hood, which quickly absorbs the flying paper scraps and transports them to the dust collection bin of the vacuum cleaner through the dust hood and connecting pipe. This design of cutting and dust collection linkage not only ensures efficient cutting of corrugated paper, but also effectively controls dust pollution in the production process.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 As shown, this utility model is a corrugated cardboard cutting device, including a support frame 111, and further including: a conveying unit 1, which is installed on the support frame 111 for conveying corrugated paper; a positioning unit 2, which is set on the support frame 111 for positioning the corrugated paper during conveying to prevent it from shifting during conveying and affecting cutting; and a cutting unit 3, which is installed on the support frame 111 for cutting the corrugated paper; wherein, after the corrugated paper is placed in the conveying unit 1, the positioning unit 2 is immediately activated to position it to prevent the corrugated paper from shifting during the conveying process of the conveying unit 1 and affecting cutting. After the positioning unit 2 completes the positioning of the corrugated paper, the conveying unit 1 can convey the corrugated paper to the cutting unit 3 for cutting, and at the same time treat the dust generated during the cutting process.

When the drive assembly 22 is activated, it drives the positioning assembly 21 to position the corrugated paper 113 on the slitting conveyor belt 112, preventing the corrugated paper from shifting during movement. The positioning assembly 21 includes L-shaped plates 211 fixedly connected to both sides of the conveying unit 1. Two slide rods 212 are fixedly connected to the side of the two L-shaped plates 211 that are close to each other. Two sliders 213 are slidably connected to the outer walls of the two slide rods 212. Guide roller clamps 214 are fixedly connected to the bottom of each slider 213, and both guide roller clamps 214 are in contact with the corrugated paper 113. During the positioning process of corrugated paper 113, the guide roller clamp 214 is equipped with guide rollers that can reduce the friction of corrugated paper 113 during positioning, ensuring that corrugated paper 113 can still move with the slitting conveyor belt 112 after positioning is completed.

The ends of the two connecting rods 226 away from the slider 225 are both hinged to the two sliders 213.When slider 225 moves, it drives slider 1 213 connected to it via two connecting rods 226, causing the guide roller clamps 214 on slider 1 213 to move closer together, thereby positioning the corrugated paper 113. By setting the positioning part 2, in use, the corrugated paper 113 is first placed in the middle of the slitting conveyor belt 112, and then the hydraulic push rod 223 is activated. The hydraulic push rod will push slider 225 to slide linearly along the track 224. Since the top of slider 225 is connected to two symmetrically distributed connecting rods 226 via hinge shafts, and the other ends of the connecting rods 226 are respectively hinged to slider 1 213 sliding on the slide rod 212, a four-bar linkage mechanism is formed. The push rod 223 continuously pushes, and the second slider 225 drives the two first sliders 213 to slide towards each other on the slide rod 212 via the connecting rod 226. The guide roller clamps 214 installed at the bottom of the first slider 213 also move closer together, clamping and positioning the corrugated paper 113 on both sides of the slitting conveyor belt 112. The guide roller clamps 214 are equipped with freely rotating guide rollers, which effectively reduce the friction with the surface of the corrugated paper during positioning. This allows the corrugated paper to be smoothly conveyed forward under the drive of the slitting conveyor belt 112 even when positioned, ensuring the smooth progress of subsequent slitting processes. This design achieves precise positioning of the corrugated paper and ensures the integrity and continuity of material conveying, significantly improving equipment production efficiency.

A guide roller clamp 214 is connected, and both guide roller clamps 214 are in contact with the corrugated paper 113. During the positioning process of the corrugated paper 113, the guide rollers of the guide roller clamp 214 reduce the friction on the corrugated paper 113 during positioning, ensuring that the corrugated paper 113 can still move with the slitting conveyor belt 112 after positioning.

The motor drives the rotating shaft 313 to rotate, driving multiple evenly distributed discs on the rotating shaft. A cutting disc 314 synchronously cuts the corrugated paper 113 in a circular motion. Due to the high-speed friction between the sharp edge of the cutting disc and the surface of the corrugated paper, a large amount of flying paper scraps are generated during the cutting process.
