Description

Technical Field

[0001] This application relates to corrugated cardboard processing equipment, and more particularly to a pressing structure for environmentally friendly corrugated cardboard processing. Background Technology

[0002] With the continuous development of society, corrugated paper, as an important packaging material, has been widely used in various industries, mainly in the processing of corrugated cardboard. The pressing structure of environmentally friendly corrugated paper processing usually involves an optimized pressing equipment design, the purpose of which is to combine the corrugated paper with the face paper during the production process.

[0003] A search revealed Chinese Patent Publication No. CN219325629U, which discloses a corrugated cardboard hot-pressing and laminating device. The device includes a first mounting base, a first adjusting plate, a telescopic support plate, a second adjusting plate, a mounting box, and a rectangular sleeve. One end of the rectangular sleeve is movably connected to a mounting column, and one end of the mounting column is fixedly connected to the second mounting base. A groove is formed on one side of the second mounting base, and a bearing is disposed inside the groove. A tension roller is inserted at the center of the bearing. This corrugated cardboard hot-pressing and laminating device, through the design of the corrugated paper feeding and rapid dehydration structure, allows corrugated paper with insufficient tension to regain a certain amount of tension when passing through the device. This enables more accurate positioning of the corrugated paper in subsequent processing and reduces longitudinal warping caused by insufficient tension. Furthermore, the rapid dehydration of the corrugated paper allows the folds in the middle of the corrugated paper to quickly form a relatively stable triangular support.

[0004] While the aforementioned patent, through the design of the corrugated paper feeding and rapid dehydration structure, enables corrugated paper with insufficient tension to regain a certain amount of tension when passing through the device, thus allowing for more accurate positioning of the corrugated paper in subsequent processing and reducing longitudinal warping caused by insufficient tension, and also enabling the corrugated paper to quickly form a more stable triangular support in the pleats in the middle of the corrugated paper, thereby giving the corrugated paper a certain strength and reducing the problem of insufficient strength of the final corrugated board due to compression of wet corrugated paper, the above-mentioned problem of rapid dehydration of corrugated paper is solved, but the physical pressing method without adhesives cannot be achieved, which leads to reduced quality and environmental pollution. Therefore, a pressing structure for environmentally friendly corrugated paper processing is proposed to solve the above problems. Utility Model Content

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0025] Example: A pressing structure for environmentally friendly corrugated paper processing, referring to... Figures 1 to 3 It includes a support base 1, which serves as the basic support platform for the entire pressing structure, bearing the weight of the entire equipment and various forces generated during the processing, ensuring the stable operation of the equipment. The top of the support base 1 is fixedly connected to a frame mechanism 2, which is used to fix and support the pressure roller mechanism 3, the preheating mechanism 4, the cleaning mechanism 5, etc., to ensure that the relative positions and movement relationships between the components are accurate. The frame mechanism 2 includes a right vertical plate 21, the bottom of which is fixedly connected to the top of the support base 1. The top of the support base 1 is fixedly connected to a left vertical plate 23, which serves as the main support component of the frame and is fixedly fixed to the top two sides of the support base 1. The bottom sides of the right vertical plate 21 and the left vertical plate 23 are internally threaded to the left vertical plate 23. The two sides of the crossbeam 10 are fixedly connected to the inner sides of the right vertical plate 21 and the left vertical plate 23. The outside of the right vertical plate 21 is fixedly connected to the control panel 9. The top of the support base 1 is fixedly connected to the connecting support seat 7. The inside of the connecting support seat 7 is fixedly connected to the cutting mechanism 6. The inside of the frame mechanism 2 is rotatably connected to the pressure roller mechanism 3. The pressure roller mechanism 3 presses the layers of corrugated paper together through the mutual squeezing action of the upper and lower pressure rollers 31 to form a corrugated cardboard with a certain strength and structure. The pressure roller mechanism 3 includes a lower pressure roller 31, which serves as the lower support and extrusion component during the pressing process. The two sides of the lower pressure roller 31 are fixedly connected to the bottom interior of the right vertical plate 1 21 and the left vertical plate 2 23. The inner sides of the right vertical plate 1 21 and the left vertical plate 2 23 are slidably connected to sliders 33, which are used to support and adjust the position of the upper pressure roller 36. The bottom inner sides of the right vertical plate 1 21 and the left vertical plate 2 23 are threadedly connected to anchor bolts 22. The anchor bolts 22 are installed on the bottom inner sides of the right vertical plate 1 21 and the left vertical plate 2 23 to further fix the frame mechanism 2, prevent the equipment from shaking during operation, and improve the stability and reliability of the equipment. Specifically, during the operation of the environmentally friendly corrugated paper processing and pressing structure, the corrugated paper raw material is placed on the support base 1, and the pressing parameters are set through the control screen 9. After the raw material is cleaned by the cleaning mechanism 5, it enters the preheating mechanism 4 for preheating treatment to increase the paper temperature and flexibility. Subsequently, the preheated corrugated paper enters the pressure roller mechanism 3. The lower pressure roller 31 is fixed inside the bottom side of the right vertical plate 1 21 and the left vertical plate 2 23. The upper pressure roller 36 can be adjusted in position through the slider 33. The lower pressure roller 31 squeezes each other to press the various layers of corrugated paper together. The pressed corrugated cardboard continues to move and is cut according to the set size through the cutting mechanism 6 inside the connecting support 7, finally obtaining the environmentally friendly corrugated cardboard that meets the requirements.

[0026] An adjustment component 34 is fixedly connected to the top of the slider 33 to adjust the pressure and gap between the upper pressure roller 36 and the lower pressure roller 31 to adapt to the processing requirements of corrugated paper of different thicknesses and materials. The adjustment component 34 includes multiple threaded pairs 3401. By rotating the threaded pairs 3401, the vertical position of the slider 33 can be adjusted, thereby changing the distance between the upper pressure roller 36 and the lower pressure roller 31. The external threads of the threaded pairs 3401 are connected to the inside of the top side of the right vertical plate 1 21 and the left vertical plate 2 23. A trapezoidal block 3402 is fixedly connected to the bottom of the threaded pairs 3401. The trapezoidal block 3402 is fixedly connected to the bottom of the threaded pairs 3401 to provide support and transmit force, ensuring the stability and reliability of the adjustment process. Limiting slide rods 3403 are fixedly connected to both sides of slider 33 to limit and guide the movement of slider 33, ensuring smooth sliding. Upper pressure roller 36 is rotatably connected to the inner side of slider 33, enabling stable rotation. The outer side of seamless steel tube 44 is fixedly connected to the inside of upper pressure roller 36. Self-aligning bearings 35 are slidably connected to both sides of upper pressure roller 36. Cylindrical bearings 32 are fixedly connected to the inner sides of right vertical plate 21 and left vertical plate 23. Cylindrical bearings 32 support the rotation of lower pressure roller 31, reduce friction, and improve the operating efficiency and service life of the equipment. A crossbeam 10 is fixedly connected to the top of frame mechanism 2, serving as a connection and support. A preheating mechanism 4 is fixedly connected to the bottom of crossbeam 10. Before corrugated paper enters the pressing process, the preheating mechanism 4 preheats the surface of the paper, making the fiber structure of the paper more relaxed, thereby improving the pressing effect and product quality. Specifically, during the operation of the environmentally friendly corrugated paper processing and pressing structure, the thickness and material of the corrugated paper are first adjusted according to the threaded pair 3401 in the rotating adjustment component 34. The trapezoidal block 3402 drives the slider 33, and the distance and pressure between the upper pressure roller 36 and the lower pressure roller 31 are adjusted under the guidance of the limit slide rod 3403. The corrugated paper raw material is placed on the support base 1. After the processing parameters are set by the control screen 9, the raw material is first preheated by the preheating mechanism 4 at the bottom of the top beam 10 of the frame mechanism 2 to relax the paper fibers. Then it enters the pressure roller mechanism 3. The lower pressure roller 31 rotates under the support of the cylindrical bearing 32. The upper pressure roller 36 slides through the self-aligning bearing 35 and together with the lower pressure roller 31, it squeezes the materials of each layer of corrugated paper. The pressed corrugated cardboard continues to move and is cut by the cutting mechanism 6 in the connecting support seat 7 according to the preset size, finally producing environmentally friendly corrugated cardboard that meets the requirements.

[0027] The preheating mechanism 4 includes a connecting inclined plate 41 and a seamless steel tube 44. The seamless steel tube 44 further increases the temperature of the corrugated paper by electromagnetic induction heating. This heating method can achieve more uniform heat transfer, improve the preheating effect and product quality, and play the role of supporting and installing the infrared heating tube 42. Its inclined design helps to distribute heat evenly, so that the corrugated paper can be fully preheated before entering the pressing area. The top of the connecting inclined plate 41 is fixedly connected to the bottom of the crossbeam 10. Multiple infrared heating tubes 42 are fixedly connected to the bottom of the connecting inclined plate 41, which heat the surface of the corrugated paper by radiation. It has the advantages of fast heating speed and high efficiency. Multiple electromagnetic heating coils 43 are fixedly connected inside the seamless steel tube 44. The electromagnetic heating coils 43 are installed inside the seamless steel tube 44 and generate heat through electromagnetic induction. Noise reduction components 45 are fixedly connected inside the supporting base 1. During equipment operation, the noise generated by mechanical movement and motor operation is reduced, and the working environment is improved. The sponge block 4501 has good sound absorption and sound insulation performance. Its porous structure can effectively absorb and reflect sound waves, reduce the propagation of noise, and reduce the impact of noise on operators and the surrounding environment. The noise reduction component 45 includes the sponge block 4501. The sponge block 4501 is externally fixedly connected to the inside of the support base 1. The bottom of the sponge block 4501 is fixedly connected to the rubber block 4502. The rubber block 4502 plays the role of buffering and shock absorption. The rubber material has good elasticity and damping characteristics, which can reduce the vibration generated during equipment operation and further reduce noise. The bottom of the support base 1 is fixedly connected to the support plate 8, and the inside of the crossbeam 10 is fixedly connected to the cleaning mechanism 5. Specifically, during operation, based on the characteristics of corrugated paper, the distance between the upper pressure roller 36 and the lower pressure roller 31 is adjusted by adjusting the threaded pair 3401 of the adjusting component 34. The corrugated paper raw material is placed on the support base 1. After the parameters are set by the control screen 9, the raw material first passes through the cleaning mechanism 5 in the crossbeam 10 to remove surface impurities, and then enters the preheating mechanism 4. The infrared heating tube 42 on the inclined plate 41 quickly heats the surface of the corrugated paper by radiation. At the same time, the electromagnetic heating coil 43 in the seamless steel tube 44 uniformly raises the paper temperature through electromagnetic induction. The inclined design helps to distribute the heat evenly. The preheated corrugated paper enters the pressure roller mechanism 3. The lower pressure roller 31 rotates under the support of the cylindrical bearing 32. The upper pressure roller 36 cooperates to squeeze and complete the pressing of each layer of material. The pressed cardboard is cut by the cutting mechanism 6 in the connecting support seat 7. During operation, the sponge block 4501 of the noise reduction component 45 in the support base 1 absorbs noise, and the rubber block 4502 buffers and reduces shock, finally producing qualified environmentally friendly corrugated cardboard.

[0028] Reference Figure 4 and Figure 5The cleaning mechanism 5 includes two air pumps 51, which provide the air source required for cleaning. Their output ends are connected to multiple air outlet pipes 53 through connecting pipes 52, which can deliver compressed air to various parts of the equipment that need to be cleaned. The air pumps 51 are externally fixedly connected to the inside of the crossbeam 10. The output ends of the two air pumps 51 are fixedly connected to the connecting pipes 52. Multiple air outlet pipes 53 are fixedly connected to the bottom of the connecting pipes 52. The air outlet pipes 53 are used to guide the compressed air generated by the air pumps 51 to the surface and inside of the equipment. Paper scraps, dust and other impurities are removed by high-speed airflow. Multiple discharge holes 54 are opened inside the support base 1. The discharge holes 54 are opened inside the support base 1 to discharge the cleaned impurities from the equipment and prevent them from accumulating inside the equipment. Two drive slide rails 56 are fixedly connected to the top of the support plate 8. The drive slide rails 56 are used to support and guide the movement of the collection box 55. The collection box 55 is used to collect the cleaned impurities for convenient centralized processing. A collection box 55 is fixedly connected to the top of the two drive slide rails 56. The top of the collection box 55 is fixedly connected to the bottom of the support base 1. The cutting mechanism 6 includes a cylinder 61, which serves as the power source for the cutting mechanism 6. A connecting plate 63 is fixedly connected to the drive end of the cylinder 61. The cylinder 61 moves the connecting plate 63 and the slice 64 up and down through the telescopic movement of the cylinder 61 to achieve the cutting action. The cylinder 61 is fixedly connected to the inside of the connecting support 7. The connecting plate 63 is fixedly connected to the drive end of the cylinder 61. The connecting plate 63 serves as a limit and guide to ensure the stability and accuracy of the cutting process. The connecting plate 63 is used to install and fix the cutting tool. A slice 64 is fixedly connected to the bottom of the connecting plate 63. The slice 64 can quickly and accurately cut the corrugated paper into the required size and shape. Limiting blocks 62 are fixedly connected to both sides of the connecting plate 63. The limiting blocks 62 are used to limit the range of motion of the connecting plate 63, prevent it from shifting or shaking during the cutting process, improve the cutting quality and the safety of the equipment. The two sides of the limiting blocks 62 are slidably connected inside the connecting support base 7. Specifically, during equipment operation, the distance between the upper pressure roller 36 and the lower pressure roller 31 is first adjusted according to the specifications of the corrugated paper by adjusting the component 34. The corrugated paper raw material is placed on the support base 1. After the parameters are set by the control panel 9, the raw material first passes through the cleaning mechanism 5 in the crossbeam 10. Two air pumps 51 generate compressed air, which is transported to the air outlet pipe 53 through the connecting pipe 52. The high-speed airflow sweeps the surface of the corrugated paper and the inside of the equipment to remove paper scraps, dust and other impurities. The cleaned impurities fall through the discharge hole 54 in the support base 1 and are received by the collection box 55 on the drive slide rail 56. Subsequently, the corrugated paper enters the preheating mechanism 4, where it is preheated by both the infrared heating tube 42 and the electromagnetic heating coil 43. Then, it enters the pressure roller mechanism 3 to complete the pressing of each layer of material. The pressed paperboard continues to move forward, and the cylinder 61 of the cutting mechanism 6 drives the connecting plate 63, which in turn drives the slicer 64 to move up and down under the guidance of the limit block 62. The paperboard is accurately cut according to the set size, and finally, environmentally friendly corrugated paperboard that meets the requirements is produced.

[0029] The implementation principle of this application embodiment is as follows: First, by activating the infrared heating tube 42 and connecting it through the inclined plate 41, the infrared heating tube 42 preheats the paper material, which then enters between the lower pressure roller 31 and the upper pressure roller 36. The upper pressure roller 36 contains a seamless steel tube 44, and inside the seamless steel tube 44 are multiple electromagnetic heating coils 43 for heating. By rotating multiple threaded pairs 3401, the trapezoidal block 3402 is moved, which in turn drives the slider 33 to slide. The limiting slide rods 3403 on both sides slide inside the right vertical plate 21 and the left vertical plate 23 to limit the movement, thereby adjusting the gap between the pressure rollers to the thickness of the paperboard. During use, the sponge block 4501 and the rubber block 4502 collect noise, achieving physical compression molding without adhesives, reducing environmental pollution, and effectively achieving high-quality paperboard molding.

[0030] Secondly, when the right upright plate 21 and the left upright plate 23 are in use, the air pump 51 is started and the air is transmitted into the connecting pipe 52, and then multiple air outlets 53 are used to clean the surfaces of the right upright plate 21 and the left upright plate 23. The air then enters the collection box 55 through the discharge hole 54 for collection. The collection box 55 slides through the drive slide rail 56. While pressing, it is pushed by the cylinder 61, which drives the connecting plate 63 and the slice 64 to move downwards to cut the corrugated paper. The limiting block 62 limits the movement to keep the working environment clean and ensures the stability of the cutting process. After cutting, the paper is quickly collected.
