Description

Technical Field

[0001] This utility model relates to the field of decorative paper processing, specifically a paper cutting device for a back coating machine used in decorative paper processing. Background Technology

[0002] Decorative paper is an essential raw material in many building materials products, such as low-pressure boards and high-pressure boards used in furniture and cabinets, as well as fireproof boards and flooring. In the product structure, decorative paper is placed under the surface paper, mainly to provide decorative patterns and to cover and prevent the adhesive from seeping through. This layer requires the paper to have good opacity, impregnation and printability. Decorative paper requires a smooth surface, good absorption and adaptability. For paper with a base color, the color tone should be uniform, and for colored paper, the color should be bright. In the production process of decorative paper, after printing, a layer of adhesive needs to be applied to the back of the decorative paper. After applying the adhesive, it is cooled (dry adhesive). After cooling, the decorative paper is cut into sheets for collection. Therefore, a paper cutting device is set up to cut the decorative paper.

[0003] According to Chinese Patent Publication No. CN217256468U, a paper cutting device for a back coating machine for decorative paper processing is disclosed. This utility model ensures cutting accuracy and improves cutting efficiency by setting the extension and retraction speed of the telescopic rod. Furthermore, the extension and retraction of the telescopic rod causes the blade to move to the right for cutting, thereby avoiding the increase in labor caused by manual cutting and reducing costs.

[0004] Regarding the aforementioned patent content, a paper-cutting mechanism is provided to cut the decorative paper. The cut decorative paper falls onto an arc-shaped guide plate and slides into the collection box. However, some of the cut decorative paper may adhere to the guide plate and be difficult to slide into the collection box. Over time, this may lead to a large amount of decorative paper accumulating on the guide plate, requiring workers to manually remove the accumulated decorative paper, which is troublesome and affects the efficiency of decorative paper collection. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a paper cutting device on a back coating machine for decorative paper processing, so as to solve the technical problem that some decorative paper may accumulate on the guide plate and be difficult to slide into the collection box.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paper cutting device for a back coating machine for decorative paper processing, comprising a back coating machine body, a collection box, and a movable plate. Spring rods are installed on the upper side and the lower side of one side of the movable plate, and one end of the spring rod is connected to a pressure plate. A guide plate is fixed on the lower side of one side of the back coating machine body. A pushing assembly is provided on the guide plate, and the pushing assembly includes two side plates located on the top of the guide plate. A motor is installed on the outer surface of one of the side plates, and the output end of the motor is connected to a drive shaft. A rotating rod is installed on the drive shaft, and the top end of the rotating rod is connected to the pushing plate.

[0007] By adopting the above technical solution, when it is necessary to push the decorative paper that has fallen onto the guide plate into the collection box, the motor can be started. The motor can drive the drive shaft to rotate, which in turn drives the rotating rod to rotate, and then drives the pusher plate to rotate.

[0008] Furthermore, a mounting frame and a material guide frame are provided on one side of the back coating machine body, and an electric push rod is installed on the inner side of the mounting frame.

[0009] By adopting the above technical solution, the electric push rod can be installed inside the mounting frame, and the operation of the electric push rod can drive the blade to move.

[0010] Furthermore, the output end of the electric push rod is equipped with a movable plate via a piston rod, and a blade is provided on one side of the movable plate.

[0011] By adopting the above technical solution, when the electric push rod is working, the piston rod can be extended, which in turn drives the movable plate to move. The movable plate then drives the blade to move so that the blade can cut the decorative paper.

[0012] Furthermore, the inner wall of the mounting frame is provided with two sliding grooves, and a slider is provided inside the sliding groove.

[0013] By adopting the above technical solution, the slider can slide inside the groove, thereby guiding the movable plate.

[0014] Furthermore, the slider is connected to the movable plate, and the movable plate is slidably connected to the slide groove via the slider.

[0015] By adopting the above technical solution, the movable plate can drive the slider to slide inside the groove when it moves, thereby improving the stability of the movable plate when it moves.

[0016] Furthermore, a U-shaped plate is provided on one side of the top of the back coating machine body, and a rotating shaft is provided on one side of the inside of the U-shaped plate, with a baffle installed on the rotating shaft.

[0017] By adopting the above technical solution, the baffle can block the decorative paper, causing it to move downwards and preventing it from moving to the left, thus facilitating subsequent cutting of the decorative paper.

[0018] Furthermore, the guide plate is arc-shaped, and one side of the bottom of the guide plate is in contact with the collection box.

[0019] By adopting the above technical solution, the cut decorative paper can fall onto the guide plate and then slide down into the collection box.

[0020] Furthermore, a control panel is installed on one side of the outer surface of the back coating machine body, and the control panel is electrically connected to the motor and the electric push rod respectively.

[0021] By adopting the above technical solution, it is convenient for staff to start or stop the motor and electric actuator through the control panel.

[0022] Furthermore, one side of the pressure plate is smooth, and the blade is located between the two pressure plates.

[0023] By adopting the above technical solution, the pressure plate can hold down the decorative paper, preventing the decorative paper from shaking and affecting the cutting accuracy when the blade is cutting the decorative paper.

[0024] Furthermore, the pusher plate is arc-shaped and is located above the guide plate.

[0025] By adopting the above technical solution, the decorative paper on the guide plate can be moved quickly when the pusher plate rotates, so that the decorative paper can fall into the collection box.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model is equipped with a pushing component. When it is necessary to push the decorative paper that has fallen onto the guide plate into the collection box, the motor can be started. The motor can drive the drive shaft to rotate, which in turn drives the rotating rod to rotate, and then drives the pushing plate to rotate. After the pushing plate rotates and comes into contact with the decorative paper on the guide plate, as the pushing plate continues to rotate, it can push the decorative paper to slide quickly on the guide plate so that the decorative paper can slide into the collection box. This avoids some decorative paper accumulating on the guide plate and making it difficult to slide into the collection box, thereby improving the collection effect of decorative paper.

[0028] 2. This utility model incorporates a spring rod and a pressure plate. When the movable plate moves the blade, it simultaneously moves the spring rod and the pressure plate. The pressure plate first contacts the decorative paper. As the movable plate continues to move, the pressure plate squeezes the spring rod, causing it to compress. At the same time, the pressure plate, subjected to the reaction force of the spring rod, presses down on the decorative paper, thereby improving its stability and preventing it from shaking during cutting, which would affect the cutting accuracy. This improves the cutting effect of the blade on the decorative paper and ensures a more precise and even cut. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1:

[0038] A paper cutting device for a back-coating machine used in decorative paper processing, such as Figures 1-5 As shown, the back coating machine includes a main body 1, a collection box 17, and a movable plate 12. A guide plate 16 is fixed to the lower side of one side of the main body 1. A pusher assembly 9 is provided on the guide plate 16. A mounting frame 6 and a guide frame 15 are also provided on one side of the main body 1. An electric push rod 7 is installed inside the mounting frame 6. The electric push rod 7 can be installed inside the mounting frame 6. When the electric push rod 7 is working, it can drive the blade 11 to move. The output end of the electric push rod 7 is connected to the movable plate 12 through a piston rod. A blade 11 is provided on one side of the movable plate 12. When the electric push rod 7 is working, it can extend the piston rod, thereby driving the movable plate 12 to move. The movable plate 12 then drives the blade 11 to move so that the blade 11 can cut the decorative paper.

[0039] Specifically, a U-shaped plate 3 is provided on one side of the top of the back coating machine body 1. A rotating shaft 4 is provided on one side of the inside of the U-shaped plate 3, and a baffle 5 is installed on the rotating shaft 4. The baffle 5 can block the decorative paper, allowing the decorative paper to move downward and preventing it from moving to the left, which facilitates the subsequent cutting of the decorative paper. The guide plate 16 is arc-shaped, and one side of the bottom of the guide plate 16 is in contact with the collection box 17 so that the cut decorative paper can fall onto the guide plate 16 and then slide down into the collection box 17. A control panel 2 is installed on one side of the outer surface of the back coating machine body 1. The control panel 2 is electrically connected to the motor 902 and the electric push rod 7, respectively, so that the operator can start or stop the motor 902 and the electric push rod 7 through the control panel 2.

[0040] See Figures 2-5 Spring rods 8 are installed on the upper side and the lower side of one side of the movable plate 12. One end of the spring rod 8 is connected to a pressure plate 10. One side of the pressure plate 10 is smooth. The blade 11 is located between the two pressure plates 10 so that the pressure plate 10 presses down on the decorative paper and prevents the decorative paper from shaking when the blade 11 cuts the decorative paper, thus affecting the cutting accuracy.

[0041] Specifically, the pushing assembly 9 includes two side plates 901 located on the top of the guide plate 16. A motor 902 is mounted on the outer surface of one side plate 901, and the output end of the motor 902 is connected to a drive shaft 903. A rotating rod 904 is mounted on the drive shaft 903, and a pushing plate 905 is connected to the top of the rotating rod 904. When it is necessary to push the decorative paper that has fallen onto the guide plate 16 into the collection box 17, the motor 902 can be started. The operation of the motor 902 can drive the drive shaft 903 to rotate, which in turn drives the rotating rod 904 to rotate, and then drives the pushing plate 905 to rotate. The pushing plate 905 is arc-shaped and located above the guide plate 16 so that when the pushing plate 905 rotates, it can drive the decorative paper on the guide plate 16 to move quickly, so that the decorative paper can fall into the collection box 17.

[0042] Example 2:

[0043] Based on the above embodiment 1, since the electric push rod 7 can drive the movable plate 12 to move when it is working, in order to improve the stability of the movable plate 12 when it moves, the following structure will be set to guide the movable plate 12.

[0044] See Figures 1-3 The inner wall of the mounting frame 6 is provided with two sliding grooves 13. A slider 14 is provided inside the sliding groove 13. The slider 14 is connected to the movable plate 12. The movable plate 12 is slidably connected to the sliding groove 13 through the slider 14, so that when the movable plate 12 moves, it can drive the slider 14 to slide inside the sliding groove 13, thereby guiding the movable plate 12 and improving the stability of the movable plate 12 when it moves.

[0045] The working principle of this utility model is as follows: First, the operator can install the paper cutting device and connect it to the power supply. When the decorative paper is coated with glue and cooled, it is conveyed outward. The decorative paper moves downward by the obstruction of the baffle 5. Then, the electric push rod 7 is activated, which drives the movable plate 12 to move. The movable plate 12 drives the blade 11 and the pressure plate 10 to move. The pressure plate 10 first contacts the decorative paper. As the movable plate 12 continues to move, the pressure plate 10 will squeeze the spring rod 8, causing the spring rod 8 to be compressed. At the same time, the pressure plate 10 will press the decorative paper by the reaction force of the spring rod 8. At this time, the blade 11 can cut the decorative paper. After cutting, the electric push rod 7 works to retract the piston rod, which in turn drives the movable plate 12 to reset and move, and drives the blade 11 and the pressure plate 10 to reset and move, so that the pressure plate 10 no longer presses the decorative paper, which is convenient for subsequent cutting of the decorative paper.

[0046] The cut decorative paper falls from the guide frame 15 onto the arc-shaped guide plate 16. At this time, the motor 902 can be started. The motor 902 drives the drive shaft 903 to rotate, which in turn drives the rotating rod 904 to rotate, and then drives the pusher plate 905 to rotate. After the pusher plate 905 rotates and comes into contact with the decorative paper on the guide plate 16, as the pusher plate 905 continues to rotate, it can push the decorative paper to slide quickly on the guide plate 16 so that the decorative paper slides into the collection box 17, thereby achieving the purpose of collecting the decorative paper.
