Abstract
Description
Technical Field
[0001] This utility model belongs to the field of impregnated paper production technology, and specifically relates to a cutting device for producing impregnated paper. Background Technology
[0002] Impregnated paper is made from a mixture of nonwoven wood pulp, PE, and plant fibers, and has superior absorbency and solvent resistance. The production process of impregnated paper involves processes such as impregnation, drying, coating, alignment, traction, and shearing.
[0003] Currently, during the cutting of impregnated paper, jagged edges occasionally appear at the cut, affecting product quality. The main reason for this is that the existing impregnated paper cutting device lacks a paper-pressing mechanism to hold the impregnated paper in place, which makes it impossible to ensure the stability of the impregnated paper during cutting, resulting in jagged edges at the cut. In addition, after the impregnated paper is cut, during the process of conveying the paper from one conveyor to the next, paper jams occasionally occur at the connection between the two conveyors, affecting production efficiency.
[0004] Therefore, there is an urgent need for a cutting device for producing impregnated paper to solve the above problems. Utility Model Content
[0005] To address the aforementioned deficiencies in the existing technology, this utility model provides a cutting device for producing impregnated paper, comprising a first conveyor, a second conveyor, and a cutting mechanism. The first and second conveyors are respectively located on the left and right sides of the cutting mechanism. The cutting mechanism includes a frame, a lifting cylinder, a support platform, and a fan. The lifting cylinder and the support platform are vertically opposite each other. The cylinder seat of the lifting cylinder is fixed to the top of the frame. A crossbeam is fixed on the piston rod of the lifting cylinder, and paper-pressing components for pressing paper are respectively provided on the left and right sides of the crossbeam. A cutting blade is fixedly installed at the bottom end of the piston rod of the lifting cylinder. The support platform is located between the first and second conveyors. The cross-section of the support platform is inverted trapezoidal. Multiple air outlets are opened on the side of the support platform near the second conveyor. A ventilation chamber connected to the multiple air outlets is provided inside the support platform. The fan is located at the bottom of the frame, and the air outlet of the fan is connected to the ventilation chamber of the support platform through an air blowing pipe.
[0006] Optionally, both paper pressing assemblies are located below the crossbeam. Each paper pressing assembly includes a fixed plate, a pressing plate, and a connecting rod. The fixed plate and the pressing plate are parallel to each other and arranged vertically. The top surface of the fixed plate is fixedly connected to the crossbeam through the connecting rod. Two compression springs are connected between the pressing plate and the fixed plate. Two guide rods are fixed on the top surface of the pressing plate, and the two guide rods are respectively inserted into the two compression springs. The top ends of the two guide rods pass through the fixed plate and are fixed with a fixing plate, and the fixing plate is located above the fixed plate.
[0007] Alternatively, in its natural state, the bottom of the pressure plate is lower than the bottom of the shearing blade.
[0008] Specifically, this allows the pressure plate to contact the impregnated paper first during cutting, thereby pressing down on the impregnated paper to ensure its stability before cutting, thus reducing the occurrence of rough edges.
[0009] Optionally, the first conveyor and the second conveyor are respectively provided with a first conveyor belt and a second conveyor belt, and a first idler group and a second idler group are respectively provided below the first conveyor belt and the second conveyor belt.
[0010] Specifically, both the first and second idler sets serve a supporting function.
[0011] Optionally, the top surface of the support platform is at the same height as the top surfaces of the first conveyor belt and the second conveyor belt.
[0012] Optionally, a support frame is fixed below the support platform, and the bottom end of the support frame is fixed to the bottom of the machine frame.
[0013] This invention also includes other components that enable the normal operation of a cutting device for producing impregnated paper, all of which are conventional techniques in the art. Furthermore, any devices or components not specified in this invention employ conventional techniques in the art, such as lifting cylinders, fans, first conveyors, and second conveyors.
[0014] The working principle of this utility model is as follows: During use, the impregnated paper is placed on the first and second conveyors and conveyed from left to right. After the impregnated paper moves to the specified length, the lifting cylinder is controlled to extend the piston rod, driving the shearing blade and the paper pressing assembly to move down simultaneously. The paper pressing plate will first contact the impregnated paper and hold it down under the action of the compression spring. Then the shearing blade cuts the impregnated paper. After the cutting is completed, the lifting cylinder retracts the piston rod, driving the shearing blade and the paper pressing assembly to move up together. The second conveyor conveys the cut impregnated paper to the next process, while the first conveyor continues to convey the impregnated paper to the right end. At this time, the blower is started to blow air into the air pipe. The airflow blows out from the air outlet through the ventilation chamber. When the blown airflow encounters the second conveyor, some of the airflow will blow upward. In this way, when the impregnated paper passes between the first and second conveyors, the airflow will support the impregnated paper and prevent paper jamming between the support table and the second conveyor. Then the next round of cutting operation begins.
[0015] The beneficial effects of this utility model are that the first conveyor, the second conveyor, and the shearing mechanism can convey and shear the impregnated paper. The paper pressing assembly can ensure the stability of the impregnated paper during shearing, reduce the occurrence of burrs, improve the flatness of the cut, reduce the scrap rate, and ensure product quality. In addition, the side of the support table is provided with air vents, and the impregnated paper passing through can be supported by a fan to avoid paper jams and improve production efficiency.

The first conveyor 1 and the second conveyor 2 are respectively arranged on the left and right sides of the cutting mechanism. The first conveyor 1 and the second conveyor 2 are respectively provided with a first conveyor belt and a second conveyor belt, and a first idler group 3 and a second idler group 4 are respectively arranged below the first conveyor belt and the second conveyor belt. The first idler group 3 and the second idler group 4 are both for supporting purposes.
[0026] The shearing mechanism includes a frame 5, a lifting cylinder 6, a support platform 7, and a fan 8. The lifting cylinder 6 and the support platform 7 are vertically opposite each other. The cylinder seat of the lifting cylinder 6 is fixed to the top of the frame 5. A crossbeam 9 is fixed to the piston rod of the lifting cylinder 6, and paper pressing assemblies 10 for pressing paper are respectively arranged on the left and right sides of the crossbeam 9. Both paper pressing assemblies 10 are located below the crossbeam 9. Each paper pressing assembly 10 includes a fixed plate 11, a pressing plate 12, and a connecting rod 13. The fixed plate 11 and the pressing plate 12 are parallel to each other and vertically arranged. The top surface of the fixed plate 11 is fixedly connected to the crossbeam 9 through the connecting rod 13. Two compression springs 14 are connected between the pressing plate 12 and the fixed plate 11. Two guide rods 15 are fixed to the top surface of the pressing plate 12, and the two guide rods 15 are respectively inserted into the two compression springs 14. The top ends of the two guide rods 15 pass through the fixed plate 11 and are fixed with fixing plates 16, and the fixing plates 16 are located on the fixed plate. Above 11, the fixing plate 16 is to prevent the guide rod 15 from detaching from the fixing plate 11; the bottom end of the piston rod of the lifting cylinder 6 is fixedly installed with a shearing blade 17. In its natural state, the bottom surface of the pressing plate 12 is lower than the bottom end of the shearing blade 17. In this way, during shearing, the pressing plate 12 can first contact the impregnated paper 22 and then press down the impregnated paper 22 to ensure the stability of the impregnated paper 22 before cutting, so as to reduce the occurrence of burrs; the support platform 7 is located between the first conveyor 1 and the second conveyor 2. The top surface of the support platform 7 is at the same height as the top surface of the first conveyor belt and the top surface of the second conveyor belt; the cross-section of the support platform 7 is an inverted trapezoid. Multiple air outlets 18 are opened on the side of the support platform 7 near the second conveyor 2. The interior of the support platform 7 is provided with a ventilation chamber 19 that communicates with the multiple air outlets 18. The fan 8 is located at the bottom of the frame 5. The air outlet of the fan 8 is connected to the ventilation chamber 19 of the support platform 7 through the air blowing pipe 20.
[0027] In addition, a support frame 21 is fixed below the support platform 7, and the bottom end of the support frame 21 is fixed to the bottom of the frame 5.
[0028] The working principle of this utility model is as follows: During use, the impregnated paper 22 is placed on the first conveyor 1 and the second conveyor 2 and conveyed from left to right. After the impregnated paper 22 moves to a specified length, the lifting cylinder 6 is controlled to extend the piston rod, driving the shearing blade 17 and the paper pressing assembly 10 to move down simultaneously. The paper pressing plate 12 will first contact the impregnated paper 22 and press it down under the action of the compression spring 14. Then, the shearing blade 17 cuts the impregnated paper 22. After the cutting is completed, the lifting cylinder 6 retracts the piston rod, driving the shearing blade 17 and the paper pressing assembly 10 to move down together. Moving upwards, the second conveyor 2 transports the cut impregnated paper 22 to the next process, while the first conveyor 1 continues to transport the impregnated paper 22 to the right. At this time, the blower 8 is started to blow air into the air blowing pipe 20. The airflow passes through the ventilation chamber 19 and blows out from the air outlet 18. When the blown airflow encounters the second conveyor 2, some of the airflow will blow upwards. In this way, when the impregnated paper 22 passes between the first conveyor 1 and the second conveyor 2, the airflow will support the impregnated paper 22, avoiding paper jams between the support table 7 and the second conveyor 2. Then the next round of cutting operation begins.
[0029] The embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
