Description

Technical Field

[0001] This utility model relates to the field of paper cutting, and in particular to a melamine paper synchronous cutting device. Background Technology

[0002] Melamine paper is widely used in decorative building materials, furniture manufacturing and other fields. It is made by impregnating base paper with amino resin and drying it. After hot pressing, it can be glued to the substrate. It can present a variety of appearances such as wood grain and solid color. It also has wear-resistant and heat-resistant properties, which can extend the service life of the board. With the growth of market demand, the cutting process in production needs to be efficient and precise. Synchronous cutting device can match cutting and conveying, improve quality and efficiency, and meet the needs of industrial production.

[0003] In the existing technology, when the operator uses the melamine paper synchronous cutting device for cutting operations, the paper needs to be placed on one side of the inner wall of the receiving box and then manually cut. However, this method can only fix the two ends. When the cutting blade cuts vertically due to machine vibration and other reasons, the paper can still shift to both sides, which poses a risk of the paper being cut at an angle and the product quality is poor. Therefore, a melamine paper synchronous cutting device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a melamine paper synchronous cutting device, which aims to improve the problem in the prior art that "this method has the risk of some cartons being folded on one side, and the vertical cutting blade causing the paper to be cut at an angle, resulting in poor product quality".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a melamine paper synchronous cutting device, comprising a machine body, a cutting blade installed on the inner wall of the machine body, a receiving box fixedly connected to the rear surface of the machine body, a limiting component provided on the inner wall of the receiving box, the limiting component including a rotating rod, the outer wall of the rotating rod rotatably connected to the inner wall of the machine body, a fixing component provided on the front surface of the rotating rod, a gear fixedly connected to the rear surface of the rotating rod, an adjusting threaded rod fixedly connected to the rear surface of the gear, a push plate connected to the adjusting threaded rod through an adjusting component, a lower rack plate slidably connected to the inner wall of the receiving box, a connecting rod one fixedly connected to the upper surface of the lower rack plate near the left side, a left limiting plate fixedly connected to the upper surface of the connecting rod one, an upper rack plate slidably connected to the inner wall of the receiving box, a connecting rod two fixedly connected to the upper surface of the upper rack plate near the right end, a right limiting plate fixedly connected to the upper surface of the connecting rod two, and both the upper rack plate and the lower rack plate meshing with the gear.

[0006] As a further description of the above technical solution:

[0007] The rear end of the adjusting threaded rod is rotatably connected to the inner wall of the receiving box, and the outer walls of both connecting rod one and connecting rod two are slidably connected to the inner wall of the receiving box. A through groove is provided at the rear of the receiving box.

[0008] As a further description of the above technical solution:

[0009] The front surfaces of both the left and right limiting plates are sloped.

[0010] As a further description of the above technical solution:

[0011] The adjustment assembly includes a movable plate, the lower inner wall of which is threadedly connected to the outer wall of an adjusting threaded rod, and the upper inner wall of which is threadedly connected to a threaded rod.

[0012] As a further description of the above technical solution:

[0013] The front surface of the threaded rod is rotatably connected to the front surface of the push plate, and the moving plate is configured as Z-shaped.

[0014] As a further description of the above technical solution:

[0015] The fixing component includes a knob, the rear surface of which is fixedly connected to the front surface of the rotating rod, and the front surface of the body is provided with an unlocking groove.

[0016] As a further description of the above technical solution:

[0017] The rear surface of the knob is elastically connected to a pressing disc via a support spring, and a slide rod is fixedly connected to the rear surface of the knob. The outer wall of the slide rod is slidably connected to the inner wall of the pressing disc.

[0018] As a further description of the above technical solution:

[0019] The upper and lower rack plates are staggered in the vertical direction.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the limiting component allows the operator to rotate the rotating rod to make the gear rotate when the paper synchronous cutting device is cutting the paper. At this time, the left and right limiting plates will move inward synchronously, so that papers of different sizes can be arranged neatly. The push plate at the rear will also move synchronously, so that the back of the paper is arranged neatly, thus improving the quality of the products produced by the device.

[0022] 2. In this utility model, by adjusting the components and fixing the components, when the device is in use, there may be situations where the paper length is different and the rear push plate obstructs the cutting. At this time, the threaded rod can be turned by the through groove to adjust the position of the push plate individually, which enhances the adaptability of the device. In addition, the fixing component at the front of the machine body can firmly hold the machine body after the operator has adjusted it, preventing the knob from turning accidentally and enhancing the stability of the device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of a melamine paper synchronous cutting device, comprising a body 1 for supporting the overall device, a cutting blade 2 for cutting paper installed on the inner wall of the body 1, a receiving box 3 for holding the paper to be cut fixedly connected to the rear surface of the body 1, a limiting component 4 for limiting the position of the paper provided on the inner wall of the receiving box 3, the limiting component 4 including a rotating rod 41 for driving a gear 42 to rotate, the outer wall of the rotating rod 41 being rotatably connected to the inner wall of the body 1, a fixing component 5 for preventing the rotating rod 41 from rotating accidentally provided on the front surface of the rotating rod 41, a gear 42 fixedly connected to the rear surface of the rotating rod 41 for moving the upper rack plate 48 and the lower rack plate 45 by its own rotation, and simultaneously driving the adjusting threaded rod 43 to rotate, and an adjusting threaded rod 43 fixedly connected to the rear surface of the gear 42 for adjusting the movement of the moving plate 61. The adjusting threaded rod 43 is connected to a push plate 44 via the adjusting assembly 6 to push the paper back neatly. The inner wall of the receiving box 3 is slidably connected to a lower rack plate 45 to drive the connecting rod 46. The upper surface of the lower rack plate 45 near the left is fixedly connected to a connecting rod 46 to drive the left limit plate 47. The upper surface of the connecting rod 46 is fixedly connected to a left limit plate 47 to restrict the left end of the paper and prevent the paper from deflecting. The inner wall of the receiving box 3 is slidably connected to an upper rack plate 48 to drive the connecting rod 49. The upper surface of the upper rack plate 48 near the right end is fixedly connected to a connecting rod 49 to drive the right limit plate 410. The upper surface of the connecting rod 49 is fixedly connected to a right limit plate 410 to restrict the right end of the paper and prevent the paper from deflecting. Both the upper rack plate 48 and the lower rack plate 45 mesh with the gear 42.

[0033] Reference Figures 1-3 The rear end of the adjusting threaded rod 43 is rotatably connected to the inner wall of the receiving box 3. The outer walls of the connecting rod 46 and the connecting rod 49 are slidably connected to the inner wall of the receiving box 3, so that when the gear 42 rotates, the upper rack plate 48 and the lower rack plate 45 can move simultaneously. The rear of the receiving box 3 is provided with a through groove 7 for the operator to rotate the threaded rod 62. The front surfaces of the left limit plate 47 and the right limit plate 410 are both set as slopes so that the paper can be guided when it enters without having to be specifically aligned with the middle position of the left limit plate 47 and the right limit plate 410. The adjusting assembly 6 includes a moving plate 61 for driving the threaded rod 62 to move, thereby driving the push plate 44 to move. The lower inner wall of the moving plate 61 is threadedly connected to the outer wall of the adjusting threaded rod 43, and the upper inner wall of the moving plate 61 is threadedly connected to the threaded rod 62 for moving the push plate 44 back and forth by rotating itself.

[0034] Reference Figures 3-5The front surface of the threaded rod 62 is rotatably connected to the front surface of the push plate 44. The moving plate 61 is Z-shaped. The fixing component 5 includes a knob 51 for easy rotation of the rotating rod 41 by the operator. The middle of the rear surface of the knob 51 is fixedly connected to the front surface of the rotating rod 41. The front surface of the machine body 1 is provided with an unlocking groove 54 for easy removal of the extrusion plate 53 from the front surface of the machine body 1 by the operator. The rear surface of the knob 51 is elastically connected to an extrusion plate 53 made of rubber, which is used to press against the front surface of the machine body 1 to increase the contact friction and prevent the knob 51 from rotating accidentally. The rear surface of the knob 51 is fixedly connected to a slide rod 55. The outer wall of the slide rod 55 is slidably connected to the inner wall of the extrusion plate 53. The upper rack plate 48 and the lower rack plate 45 are offset in the vertical direction to prevent the connecting rod 46 from obstructing the movement of the upper rack plate 48.

[0035] Working principle: First, place the melamine paper to be cut into the receiving box 3. Then, lift the pressing disc 53 forward through the unlocking slot 54. Next, rotate the knob 51 according to the required cutting size. Rotating the knob 51 drives the rotating rod 41 to rotate, which in turn drives the gear 42 to rotate. The gear 42 meshes with the upper rack plate 48 and the lower rack plate 45, causing them to move in opposite directions. Simultaneously, connecting rod 1 46 and connecting rod 2 49 are subjected to force and move, driving the left limiting plate 47 and the right limiting plate 410 towards the center until both ends of the paper are fixed. Then, the gear 42 rotates... At the same time, gear 42 also drives the adjusting threaded rod 43 to rotate. The lower part of the moving plate 61 is blocked by the inner wall of the receiving box 3, so the moving plate 61 will move back and forth along the adjusting threaded rod 43, so that the back of the paper is also pushed flat. When the paper to be cut is long, you can reach in from the inside of the through slot 7 and then rotate the threaded rod 62. The rotation of the threaded rod 62 drives the push plate 44 to move back and forth to adapt to different sizes of paper. After the adjustment is completed, the pressing plate 53 is released. The pressing plate 53 is firmly fixed to the surface of the machine body 1 under the action of the support spring 52, increasing the friction to prevent the knob 51 from rotating accidentally.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
