Description

Technical Field

[0001] This invention relates to the field of paper processing machinery, and more specifically, to a slitting and correction device for coated base paper. Background Technology

[0002] This device is used for the slitting and pre-treatment of coated base paper for food paper cups. The coated base paper is composed of a paper base and a PE coating layer. The paper is soft and easy to stretch, and the coating is thin and easily scratched. It is extremely easy to deviate and warp under the influence of tension and airflow. In production, longitudinal slitting process is mostly adopted, and a circular knife is used to cut the wide base paper into multiple sets of narrow cup raw materials along the paper feeding direction.

[0003] Currently, most coating base paper slitting devices on the market use slitting molds with fixed spacing. When the slitting width needs to be adjusted, the molds need to be frequently disassembled and replaced, which is not only cumbersome to operate but also reduces production efficiency. At the same time, most devices have poor surface cleaning effects, and dust and fine impurities adhering to the surface of the coating base paper are easy to remain on the surface of the finished product, affecting the quality of subsequent coating processes. How to invent a coating base paper slitting and correction device to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example, refer to Figures 1-13 A paper slitting and correction device for coated base paper includes a main support 1. A heating roller 4, a front support roller 6, and a rear support roller 11 are rotatably connected to the inner wall of the main support 1. A power assembly 9 and a recovery assembly 12 are provided on the outer side of the main support 1. The device is characterized by further comprising: Correction component 5 is located inside the main support 1 and is used to correct the deviation of the coated base paper. The slitting component 7 is located on one side of the power component 9. The power component 9 and the slitting component 7 work together to slitting the coated base paper. Collection component 8 is located outside the power component 9. The power component 9 and collection component 8 work together to collect the debris of coated base paper.

[0021] Furthermore, a rear support 10, a middle support 13, and a front support 2 are fixedly installed on the side walls of the main support 1. A front roller 3 is rotatably connected to the inner wall of the front support 2. The slitting assembly 7 includes a rotating plate 701, which is rotatably connected to the middle support 13. A third sprocket 706 is fixedly installed at one end of the rotating plate 701. A second chain belt 707 is driven by the third sprocket 706. A fourth sprocket 708 is driven by the second chain belt 707. The fourth sprocket 708 is fixedly connected to the outer wall of the first rotating shaft 502. The inner wall of the rotating plate 701 rotates... A straight shaft 702 is dynamically connected. A blade 703 and a small cleaning broom 704 are respectively limited and slidably connected to the outer wall of the straight shaft 702. A screw 705 is threadedly connected to the inner wall of the blade 703 and the small cleaning broom 704. The recycling component 12 includes a ninth sprocket 1201. The ninth sprocket 1201 is fixedly connected to one end of the third rotating shaft 902. The ninth sprocket 1201 is driven by a fifth chain belt 1202. The fifth chain belt 1202 is driven by a tenth sprocket 1203. The tenth sprocket 1203 is fixedly connected to the collecting roller 1204.

[0022] It should be noted that during the preparation process, the operator first loosens the screws 705 that fix the blade 703 and the small cleaning broom 704 according to the width of the coated base paper to be cut and the target narrow finished product size. Then, the blade 703 is slid along the axis of the straight shaft 702 to adjust to the preset spacing. After the adjustment is completed, the screws 705 are tightened again to fix the position of the blade 703. At the same time, the collection roller 1204 of the same size is installed.

[0023] Reference Figures 3-13 Furthermore, the correction assembly 5 includes a first motor 501, which is fixedly connected to the side wall of the main support 1. A first rotating shaft 502 is fixedly mounted at one end of the first motor 501, and a first sprocket 503 is fixedly mounted at one end of the first rotating shaft 502. A first chain belt 504 is driven by the first sprocket 503, and a second sprocket 505 is driven by the first chain belt 504. A second rotating shaft 507 is fixedly mounted at one end of the second sprocket 505. A lower support 506 is fixedly mounted on the side wall of the main support 1, and the lower support 506 is connected to the second rotating shaft 507. The outer wall is rotatably connected. A main bevel gear 508 is fixedly installed at the end of the second rotating shaft 507 away from the first chain belt 504. The main bevel gear 508 is meshed with a secondary bevel gear 509. A fifth rotating shaft 510 is fixedly installed at one end of the secondary bevel gear 509. A first gear 511 is fixedly installed at the end of the fifth rotating shaft 510 away from the main bevel gear 508. A toothed belt 512 is meshed with the first gear 511. A correction plate 513 is fixedly installed on the outer wall of the toothed belt 512. The correction plate 513 is slidably connected to the heating roller 4, the front support roller 6, and the front end roller 3, respectively.

[0024] It should be noted that during equipment specification adaptation and operational adjustments, the first motor 501 drives the first rotating shaft 502 to rotate. The first rotating shaft 502 serves as a common power main shaft, synchronously transmitting power to the correction assembly 5 and the slitting assembly 7. The power is transmitted through the first sprocket 503, the first chain belt 504, and the second sprocket 505, driving the second rotating shaft 507 to rotate. Subsequently, through the reversal of the main bevel gear 508 and the secondary bevel gear 509, the fifth rotating shaft 510 and the first gear 511 drive the toothed belt 512 to move laterally, thereby driving the correction plate. The paper slides left and right, and the two correction plates 513 cooperate with each other to closely adhere to the two edges of the coated base paper, limiting and aligning the paper web to ensure that the base paper is always conveyed along the center position. At the same time, the fourth sprocket 708, which is fixed on the same axis, rotates synchronously. The power is transmitted to the third sprocket 706 through the second chain belt 707, which drives the rotating plate 701 and the straight shaft 702 to rotate synchronously. This drives the slitting unit, which consists of the blade 703, the small cleaning broom 704, the straight shaft 702, and the screw 705, to adjust as a whole until the slitting unit is aligned with the coated base paper.

[0025] Based on the standard coated base paper size, the total travel of the toothed belt 512 is divided into four segments. The number of rotations of the first motor 501 synchronously controls the travel distance of the correction plate 513 and the rotation amplitude of the rotating plate 701. When the first motor 501 rotates in the reverse direction, driving the correction plate 513 to the maximum spacing position, it synchronously drives the slitting assembly 7 to switch to the maximum slitting station, so that all blades 703 are aligned with the coated base paper in the center. As the first motor 501 continues to rotate in the forward direction, the spacing of the correction plate 513 shrinks sequentially to the remaining three travel segments, and the number of slitting units put into operation is also reduced accordingly until the correction plate 513 reaches the minimum spacing, and the number of slitting units used is also reduced to the minimum. Regardless of the gear, the blades 703 are always aligned with the coated base paper in the center, thereby achieving synchronous matching between the correction limit width and the number of slitting stations.

[0026] The coated base paper to be processed is sequentially wound around the front roller 3, the heating roller 4, the front support roller 6, and the rear support roller 11, and its end is fixed to the collection roller 1204 of the recycling component 12. Then, the coated base paper is smoothly conveyed forward from the feed end through the front roller 3, the heating roller 4, and the front support roller 6. The heating roller 4 rotates synchronously with the paper path and continuously heats the paper inside. The constant temperature roller surface heats and shapes the coated base paper in the process of moving, so as to smooth the wrinkles on the paper surface, alleviate the warping of the PE coating layer caused by cooling, and ensure the flatness of the paper surface. During the continuous conveying process, the infrared offset sensor matched with the correction component 5 monitors the paper edge position in real time. Once the coated base paper is detected to be shifted to the left or right or deviated from the standard conveying track, the equipment immediately triggers the correction action.

[0027] Reference Figures 5-13 Furthermore, the power assembly 9 includes a second motor 901, which is fixedly connected to the side wall of the main support 1. A third rotating shaft 902 is fixedly mounted on the output end of the second motor 901. A fifth sprocket 903 is fixedly mounted on the outer wall of the third rotating shaft 902. The fifth sprocket 903 is driven by a third chain belt 904, which is driven by a sixth sprocket 905. A fourth rotating shaft 906 is fixedly mounted on one end of the sixth sprocket 905. A [missing information - likely a component or material] is fixedly mounted on the outer wall of the fourth rotating shaft 906. The seventh sprocket 907 is connected to the fourth chain belt 908, which is connected to the eighth sprocket 909. The inner wall of the eighth sprocket 909 is fixedly mounted with a fixed shaft 910. One end of the fixed shaft 910 is fixedly mounted with a medium gear 911. The medium gear 911 and the fixed shaft 910 are rotatably connected to the outer wall of the rotating plate 701. The medium gear 911 is meshed with a pinion 912, which is fixedly connected to the end of the straight shaft 702 away from the rotating plate 701.

[0028] It should be noted that when the equipment starts processing, the second motor 901 starts running, driving the third rotating shaft 902 to rotate. The third rotating shaft 902 drives the ninth sprocket 1201 to rotate synchronously. The ninth sprocket 1201 transmits power to the tenth sprocket 1203 through the fifth chain belt 1202. The tenth sprocket 1203 drives the collecting roller 1204 to rotate at a constant speed. With the winding pull of the collecting roller 1204, the entire roll of coated base paper is continuously pulled, causing it to be conveyed forward at a constant speed along the paper path formed by the front roller 3, the heating roller 4, the front support roller 6, and the rear support roller 11, thereby providing stable paper feeding power for continuous slitting operations.

[0029] Meanwhile, the third shaft 902 drives the fifth sprocket 903 to rotate. The fifth sprocket 903 drives the sixth sprocket 905 through the third chain belt 904, which in turn causes the fourth shaft 906 to rotate synchronously. The seventh sprocket 907 on the fourth shaft 906 transmits power to the eighth sprocket 909 through the fourth chain belt 908. The eighth sprocket 909 drives the fixed shaft 910 and its gear 911 to rotate together. The gear 911 drives the pinion 912 to rotate through gear meshing. The pinion 912 then drives the straight shaft 702 to rotate continuously. The blade 703, which is mounted on the straight shaft 702 and has been positioned and locked according to the product specifications, rotates at high speed to longitudinally cut the coated base paper that has been corrected and centered, thereby cutting the wide base paper into multiple finished paper strips that meet the width requirements.

[0030] Meanwhile, the small cleaning broom 704, installed on the same straight shaft 702, is made of a softer material, which can prevent damage to the coated base paper due to excessive stress. While the blade 703 is cutting, the small cleaning broom 704 promptly removes paper fibers, debris, and surface dust generated at the cutting position, thereby preventing impurities from getting stuck in the cut and affecting the cutting quality. The narrow strip of paper after cutting is finally pulled and neatly wound up by the collecting roller 1204, realizing the synchronous and continuous operation of paper feeding, cutting, debris removal and winding.

[0031] Reference Figures 6-13 Furthermore, the collection assembly 8 includes a collection box 801, which is fixedly connected to the side wall of the main support 1. A filter plate 804 is fixedly connected to the inner wall of the collection box 801. The collection box 801 is rotatably connected to the outer wall of the third rotating shaft 902. A planetary gear 802 is fixedly installed on the outer wall of the third rotating shaft 902. A fan blade 803 is fixedly connected to the outer wall of the planetary gear 802. The fan blade 803 is located at the lower end of the filter plate 804. A large cleaning broom 805 is rotatably connected to one end of the fourth rotating shaft 906. The large cleaning broom 805 is located above the filter plate 804. The fourth rotating shaft 906 passes through the inner wall of the main support 1 and is rotatably connected to the inner wall of the collection box 801. The large cleaning broom 805 is rotatably connected to the inner wall of the collection box 801.

[0032] It should be noted that when the second motor 901 drives the third rotating shaft 902 to operate continuously to achieve synchronous paper feeding and slitting operations of the whole machine, the third rotating shaft 902 simultaneously drives the planetary gear 802 located in the collection box 801 to rotate. The planetary gear 802 drives the fan blade 803 to rotate, making it rotate at high speed. The high-speed rotating fan blade 803 continuously stirs the air in the box below the filter plate 804, causing the airflow to enter the collection box 801 from the fine holes of the filter plate 804 and flow outward through the fine holes of the box body. This creates a stable negative pressure environment in the space below the filter plate 804. Under the action of this negative pressure suction, paper scraps, dust and other impurities that fall off the coated base paper during the cleaning and slitting process are sucked downward and finally fall to the upper surface of the filter plate 804. The filter plate 804 can effectively block solid debris, while the airflow passes through the filter holes and is discharged from the bottom of the box body.

[0033] Meanwhile, the fourth rotating shaft 906, in conjunction with the third rotating shaft 902, drives the large cleaning broom 805 to continuously rotate and sweep the upper surface of the filter plate 804, thereby scraping away the paper dust and chips accumulated on the underside of the paper in real time. The small cleaning broom 704 rotates synchronously with the straight shaft 702 and the blade 703, and its position is close to the upper surface of the coated base paper. During the slitting process, it scrapes away the paper dust and chips on the upper side of the paper in real time to complete the cleaning of impurities on the paper surface and prevent impurities from adhering to the surface of the finished coated base paper. The removed impurities are temporarily stored on the filter plate 804 and can be opened for unified cleaning after the equipment is stopped.

[0034] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
