Description

Technical Field

[0001] The invention relates to the technical field of slitting devices, in particular to a special five-layer corrugated paper slitting device. Background Art

[0002] Since the five-layer corrugated paper made of traditional pure paper-based materials is difficult to meet the market's increasing demand for refined packaging of different products, and cannot meet the demand for adequate protection of different types of products, improvements are made on the basis of the five-layer corrugated paper made of traditional pure paper-based materials to produce special five-layer corrugated paper. For example, when packaging electronic and electrical products, a moisture-proof layer, a buffer layer and other designs are used in the five-layer corrugated paper to achieve the purpose of fully protecting the electronic and electrical products. When packaging chemical products, a moisture-proof layer, an anti-corrosion layer and other designs are used in the five-layer corrugated paper to protect the chemical products and prevent the packaging boxes from being corroded.

[0003] For example, patent publication number CN106493994B discloses a corrugated paper cutting machine, including a cutting table, a movable frame is provided above the cutting table, a cylinder is provided on the movable frame, a motor and a rotating shaft connected to the motor are provided below the cutting table, a blade is provided on the rotating shaft, an elastic bag is provided at the lower end of the movable frame, a through groove is provided at the bottom of the elastic bag, the through groove is filled with paraffin, abrasive particles are contained in the elastic bag, a wax replenishing box is hinged on the blade, the wax replenishing box is filled with liquid paraffin, the width of the wax replenishing box is greater than the width of the through groove, the wax replenishing box is fitted with the blade, a wax outlet hole and a first magnetic sheet are provided on the side of the wax replenishing box that is in contact with the blade, a second magnetic sheet is provided on the side of the blade that is in contact with the wax replenishing box, and the first magnetic sheet and the second magnetic sheet have opposite magnetic properties.

[0004] However, in the prior art, when traditional slitting devices were first designed, they mainly targeted homogeneous corrugated paper, especially pure paper-based materials. This design concept is based on the relatively simple and stable properties of pure paper-based materials. During the cutting process, the force exerted by the material on the tool is relatively uniform, and the slitting difficulty is relatively low. However, the five-layer corrugated paper made of special materials has a complex structure. Not only do the physical properties of each layer of material vary greatly, such as hardness and toughness, but they also include functional layers with special functions, such as thermal insulation, waterproofing, and fireproofing. These functional layers are extremely physically sensitive. For example, the thermal insulation layer is made of lightweight and fragile insulation materials, and the waterproofing and fireproofing layers are achieved through special coatings or composite materials. The structural integrity of these layers is extremely vulnerable to damage. Traditional slitting devices have completely ignored these special situations and have not targeted them. The high-hardness, multi-layer heterogeneous composite structure optimizes the tool material and layout design, resulting in increased blade wear and reduced cutting accuracy when the cutting device is cutting the five-layer corrugated paper of special materials. At the same time, when performing the guided folding cutting operation on the five-layer corrugated paper of special materials, the existing cutting device lacks protection measures for the functional layer. The unsuitable tool will generate a lot of heat and excessive cutting force during cutting, which will destroy the continuity of the waterproof layer and cause the waterproof performance to decrease; for the thermal insulation layer, its internal structure will be loose, reducing the thermal insulation effect. If the fireproof layer is damaged, its fireproof performance will also be affected. Once the functional layer is damaged, the performance of the product produced by the five-layer corrugated paper of special materials will inevitably be greatly reduced, and it cannot meet the special functional requirements of the product in actual use. Summary of the invention

[0005] The purpose of the present invention is to provide a special five-layer corrugated paper cutting device to solve the problem that the traditional cutting device proposed in the above background technology is mainly targeted at homogeneous corrugated paper, especially pure paper-based materials, at the beginning of its design. This design idea is based on the relatively single and stable properties of pure paper-based materials, and does not optimize the tool material and layout design for high hardness and multi-layer heterogeneous composite structures. As a result, when the cutting device is used to cut five-layer corrugated paper of special materials, blade wear is aggravated and cutting accuracy is reduced. At the same time, when the cutting operation of guiding the folding of five-layer corrugated paper of special materials is performed, the functional layer is easily damaged, resulting in the problem that the performance of the product produced by the five-layer corrugated paper of special materials is inevitably greatly reduced, and the special functional requirements of the product in actual use cannot be met.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, according to the characteristics of the special five-layer corrugated paper substrate, matching slitting heads No. 1, No. 2 and No. 3 are selected in a targeted manner, and the No. 2 connecting shaft and the driven gear are driven by the worm gear to revolve around the driving gear, and the heights of the No. 1 slitting head and the No. 3 slitting head are adjusted. The No. 1 slitting head slits the inner layer of the special five-layer corrugated paper, and the No. 2 slitting head slits the core layer of the special five-layer corrugated paper, and finally the No. 3 slitting head slits the outer layer of the special five-layer corrugated paper.

[0017] 2. In the present invention, when only the outer layer and the inner layer of the special five-layer corrugated paper need to be processed with non-through slitting, the position of the No. 1 slitting head or the No. 3 slitting head is adjusted by the adaptive adjustment mechanism, so that the No. 1 slitting head is in the lowest position or the No. 3 slitting head is in the lowest position, so that the slitting mechanism can cut the special five-layer corrugated paper with non-through slits.

[0024] During the use of the present invention, when the special five-layer corrugated paper produced by different base materials is cut through the seam, according to the characteristics of the base material, the matching No. 1 slitting head 26, No. 2 slitting head 27 and No. 3 slitting head 28 are selected in a targeted manner, and then according to the thickness of the special five-layer corrugated paper, the worm 32 is driven to rotate by the reduction servo motor 31, so that the worm gear 33 drives the No. 2 connecting shaft 25 and the driven gear 24 to revolve around the driving gear 23 at a small angle.

[0025] Embodiment 2: According to Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10As shown, the feeding mechanism 4 includes a feeding platform 41, a No. 2 motor 42 is installed on the side of the feeding platform 41, and a conveyor belt 43 is rotated at the bottom of the feeding platform 41, the No. 2 motor 42 is used to drive the conveyor belt 43 to run, a pressure wheel 45 is arranged on the upper part of the conveyor belt 43, a No. 2 mounting frame 44 is installed on the pressure wheel 45, the No. 2 mounting frame 44 is rotatably connected with the pressure wheel 45, and a height adjustment component is installed on the side of the No. 2 mounting frame 44, the height adjustment component is composed of a bar slide rail, a bar slider and a locking screw 46, the bar slider is fixedly connected with the No. 2 mounting frame 44, and the bar slider is slidably connected with the bar slide rail, the end of the locking screw 46 passes through the bar slide rail, and the end of the locking screw 46 is connected to the The strip slider is threadedly connected, and the locking screw 46 is squeezed and fixed to the side of the strip slide rail. A No. 1 cylinder 47 is arranged on the side of the loading platform 41, and a No. 3 mounting frame 48 is fixedly connected to the top of the No. 1 cylinder 47, and a No. 3 mounting frame 48 is rotatably connected to the surface of the No. 3 mounting frame 48 with a No. 3 connecting shaft 410, and a stepper motor assembly 49 is fixedly connected to the side of the No. 3 mounting frame 48, and the stepper motor assembly 49 is used to drive the No. 3 connecting shaft 410 to rotate, and a cutting platform 411 is fixedly connected to the top of the No. 3 connecting shaft 410, and an annular slide rail 412 is fixedly connected to the upper part of the No. 3 mounting frame 48, and an annular slider 413 is slidably connected inside the annular slide rail 412, and the annular slider 413 is fixedly connected to the bottom of the cutting platform 411.

[0026] In the present invention, when performing the slitting operation of the special five-layer corrugated paper, the loading link is crucial. First, the operator carefully places the special five-layer corrugated paper on the surface of the loading platform 41. The loading platform 41 serves as a starting platform for carrying the special five-layer corrugated paper. Its structure is stable and can provide a solid foundation for subsequent loading operations. At this time, the second motor 42 is started. The second motor 42 serves as a power source to efficiently convert electrical energy into mechanical energy, driving the conveyor belt 43 to run smoothly. As the conveyor belt 43 runs, the special five-layer corrugated paper is driven by it and gradually moves to the surface of the slitting platform 411. In order to further improve the stability of the special five-layer corrugated paper during the movement, the device is equipped with a pressure wheel 45 The pressure wheel 45 is installed on the second mounting frame 44, and its function is to apply a downward pressure to the upper part of the special five-layer corrugated paper to prevent the paper from being displaced due to vibration or other external forces during movement. Considering the difference in thickness of the special five-layer corrugated paper, in order to make the pressure wheel 45 adapt to papers of different thicknesses, a function of adjusting the height of the second mounting frame 44 is designed. The operator can accurately adjust the height of the second mounting frame 44 according to the actual paper thickness. As the height of the second mounting frame 44 changes, the distance between the pressure wheel 45 and the conveyor belt 43 also changes accordingly, thereby achieving stable limiting of special five-layer corrugated paper of different thicknesses and ensuring the stability of the feeding process; When the special five-layer corrugated paper is successfully moved to the surface of the slitting table 411, if it is necessary to perform slitting on other edges of the special five-layer corrugated paper, the adjustment function of the slitting table 411 will come into play. First, the No. 1 cylinder 47 starts to work. The No. 1 cylinder 47 converts the energy of the compressed air into mechanical thrust through the internal piston movement, and lifts the No. 3 mounting frame 48. As the No. 3 mounting frame 48 rises, the height of the slitting table 411 also rises to meet the height requirements of different slitting processes. At the same time, the stepper motor assembly 49 is started. The stepper motor assembly 49 can accurately control the rotation angle and speed of the motor. The stepper motor drives the No. 3 connecting shaft 410 to rotate through the cooperation of the belt and the pulley. The No. 3 connecting shaft 410 is closely connected to the slitting table 411, thereby driving the slitting table 411 and the special five-layer corrugated paper placed on it to rotate. In this way, the different edges of the special five-layer corrugated paper can be adjusted to the bottom of the slitting mechanism 2 to achieve slitting processing on different edges; During the rotation of the slitting table 411, in order to ensure the stability of its rotation, the device adopts a combined structure of an annular slider 413 and an annular slide rail 412. The annular slide rail 412 is fixedly mounted on the No. 3 mounting frame 48, and its surface has been high-precision polished and processed to have an extremely low friction coefficient. The annular slider 413 is mounted on the bottom of the slitting table 411 and is closely matched with the annular slide rail 412. When the slitting table 411 rotates, the annular slider 413 slides along the annular slide rail 412, which effectively shares the lateral force generated when the slitting table 411 rotates, greatly improves the stability of the slitting table 411 during rotation, ensures the accuracy of the slitting process, and avoids slitting deviations caused by the shaking of the slitting table 411.

[0027] Embodiment 3: According to Figure 1 , Figure 2 , Fig.10 , Fig.11 and Fig.12 As shown, the pressing mechanism 5 includes a No. 4 mounting frame 51, a movable frame 53 and a No. 2 limiting frame 55. The No. 4 mounting frame 51 is fixedly connected to the side of the No. 2 cylinder 52, and the output end of the No. 2 cylinder 52 is fixedly connected to the scissor-type telescopic frame 54. The movable frame 53 is slidingly connected to the No. 4 mounting frame 51, and the movable frame 53 is movably connected to the scissor-type telescopic frame 54. The No. 2 limiting frame 55 is fixedly connected to the No. 4 mounting frame 51, and the No. 2 limiting frame 55 is movably connected to the scissor-type telescopic frame 54. The No. 3 cylinder 56 is fixedly connected to the bottom of the movable frame 53, and the No. 3 cylinder 56 is fixedly connected to the bottom of the pressing plate 57.

[0028] In the present invention, in the slitting process of special five-layer corrugated paper, after the special five-layer corrugated paper is accurately conveyed to the surface of the slitting table 411, it enters the material pressing stage. At this time, the material pressing mechanism 5 plays a key role. The material pressing mechanism 5 is mainly composed of a No. 2 cylinder 52, a scissor-type telescopic frame 54, a plurality of movable frames 53 and a pressing plate 57 at the bottom. In the initial state, the scissor-type telescopic frame 54 maintains a certain degree of expansion, and the plurality of movable frames 53 are arranged according to the previously set spacing distribution, and the pressing plate 57 is also in a corresponding position. When facing special five-layer corrugated paper of different sizes, the operator first measures and judges the paper size, and then starts the No. 2 cylinder 52 according to the measurement result. The No. 2 cylinder 52 is used as the whole The power driving source of the adjustment process, when receiving the adjustment command, the piston inside the No. 2 cylinder 52 starts to move under the action of air pressure. If the size of the special five-layer corrugated paper is large, it is necessary to increase the spacing between the pressure plates 57. At this time, the No. 2 cylinder 52 pulls the scissor-type telescopic frame 54 to expand outward. The scissor-type telescopic frame 54 is composed of a plurality of cross-connected connecting rods, which are connected by flexible hinges. Under the thrust of the No. 2 cylinder 52, the angle between the connecting rods of the scissor-type telescopic frame 54 gradually increases, thereby realizing the overall expansion action. As the scissor-type telescopic frame 54 is expanded, the plurality of mobile frames 53 connected thereto will move to both sides along a specific track, thereby increasing the spacing between the pressure plates 57 at the bottom of the mobile frames 53; On the contrary, if the size of the special five-layer corrugated paper is small, it is necessary to reduce the spacing between the pressure plates 57, and the No. 2 cylinder 52 pushes the scissor-type telescopic frame 54 to retract. Under the action of the thrust, the angle between the connecting rods of the scissor-type telescopic frame 54 gradually decreases, and the overall structure shrinks, driving the multiple mobile frames 53 to move closer to the middle, thereby reducing the spacing between the pressure plates 57. This method of accurately adjusting the position of the pressure plate 57 according to the size of the special five-layer corrugated paper greatly improves the stability of the slitting mechanism 2 when slitting the special five-layer corrugated paper. During the slitting process, the high-speed running tool of the slitting mechanism 2 will produce a certain impact force and friction force on the paper. If the paper is not firmly pressed, it is easy to shift, shake, etc., resulting in inaccurate slitting position and reduced slitting quality. Through the effective adjustment and pressing action of the pressing mechanism 5, the special five-layer corrugated paper can remain fixed during the slitting process, and the slitting mechanism 2 can stably slitting the paper, ensuring the accuracy and quality of the slitting, and improving production efficiency and product qualification rate.

[0029] The use method and working principle of the device are as follows: when performing through-slit cutting on special five-layer corrugated paper produced from different substrates, according to the characteristics of the substrate, the matching No. 1 slitting head 26, No. 2 slitting head 27 and No. 3 slitting head 28 are selected in a targeted manner, and then according to the thickness of the special five-layer corrugated paper, the worm 32 is driven to rotate by the reduction servo motor 31, thereby driving the worm gear 33 to rotate, and the rotation of the worm gear 33 drives the No. 2 connecting shaft 25 and the driven gear 24 to revolve along the driving gear 23. At this time, the height of the No. 1 slitting head 26 is higher than that of the No. 2 slitting head 27, and the height of the No. 3 slitting head 28 is lower than that of the No. 2 slitting head 27. The No. 1 slitting head 26 slits the inner layer of the special five-layer corrugated paper, and the No. 2 slitting head 27 slits the core layer of the special five-layer corrugated paper, and finally the No. 3 slitting head 28 slits the outer layer of the special five-layer corrugated paper; After the height adjustment of the No. 1 slitting head 26 and the No. 3 slitting head 28 relative to the No. 2 slitting head 27 is completed, the special five-layer corrugated paper is fed by the feeding mechanism 4, and then the special five-layer corrugated paper fed to the surface of the slitting table 411 is pressed and limited by the pressing mechanism 5, and then the position of the slitting mechanism 2 is adjusted by the three-axis adjustment mechanism 1, so that the slitting mechanism 2 performs slitting processing on the special five-layer corrugated paper according to the set position; When only the outer and inner layers of the special five-layer corrugated paper need to be non-through slit, the position of the No. 1 slitting head 26 or the No. 3 slitting head 28 is adjusted by the adaptor adjustment mechanism 3, so that the No. 1 slitting head 26 is in the lowest position or the No. 3 slitting head 28 is in the lowest position, so that the slitting mechanism 2 can cut the special five-layer corrugated paper with non-through seams.
