Description

Technical Field

[0001] The invention belongs to the field of material separation equipment, and in particular relates to a flaky material separation device. Background Art

[0002] In the prior art, sheet materials are generally directly divided or separated by a cutter, and some sheet materials are first processed by a scoring blade. The scoring blade scores the material in one direction so that the material is connected together through spaced dotted line-shaped connection points in this direction, which can ensure that the materials are connected together and not scattered, and also ensure that they are easy to separate from each other. Such sheet materials are generally cards, papers, cardboards, etc., such as poker cards, etc. The materials connected by the connection points are generally subsequently separated by breaking rubber rollers, that is, the connection points of the front and rear materials are disconnected through the speed difference between the two groups of rubber rollers, so that the materials are separated. However, when the breaking rubber roller breaks a single-layer material, the breaking efficiency is low, and when the multi-layer material is broken, the required pulling force is large. The breaking rubber roller needs to have sufficient pressure on the material to generate the required large pulling force on the material. However, when the rubber roller exerts a lot of pressure on the material, it will cause damage to the material such as indentation, scratches, and dirt, resulting in quality problems of the material. Therefore, it is necessary to provide a separation device that can not only separate multi-layer materials to ensure separation efficiency and separation effect, but also does not require excessive pressure to ensure the quality of the material. Summary of the invention

[0003] The object of the present invention is to provide a flaky material separation device to solve the technical problem of how to improve the separation efficiency of the above-mentioned separation device and ensure the separation effect and material quality.

[0004] To achieve the above purpose, the specific technical solution of a flaky material separation device of the present invention is as follows:

[0005] A separation device for sheet materials comprises a first roller group and a second roller group, wherein the second roller group has a faster linear speed than the first roller group, and the first roller group and the second roller group form a certain angle on the horizontal plane.

[0006] Further, the first roller group includes a first frame, a first lower roller is installed at the lower part of the first frame, and two ends of the first lower roller are rotatably connected to the side plates of the first frame through bearings. In addition, one end of the first lower roller extends to the outside of the first frame and is fixedly connected to the first sprocket, and a first upper roller is installed above the corresponding first lower roller, and two ends of the first upper roller are installed on the side plates of the first frame through adjusting components, and one end of the first upper roller also extends to the outside of the side plates of the first frame and is fixedly connected to the first sprocket; the second roller group includes a second frame, a second lower roller is installed at the lower part of the second frame, and two ends of the second lower roller are rotatably connected to the side plates of the second frame through bearings. In addition, one end of the second lower roller extends to the outside of the second frame and is fixedly connected to the second sprocket, and a second upper roller is installed above the corresponding second lower roller, and two ends of the second upper roller are installed on the side plates of the second frame through adjusting components, and one end of the second upper roller also extends to the outside of the side plates of the second frame and is fixedly connected to the second sprocket.

[0007] Furthermore, the first sprocket connected to the first lower roller and the second sprocket connected to the second lower roller are located on the same side, while the first sprocket connected to the first upper roller and the second sprocket connected to the second upper roller are located on the other side, and the diameter of the first sprocket is greater than the diameter of the second sprocket.

[0008] Furthermore, the adjustment assembly includes a slider, and both ends of the first upper roller and the second upper roller are rotatably connected to the slider through bearings respectively. At the same time, the slider is slidably connected to the side plates of the first frame and the second frame. A connecting block is fixedly connected to the upper side of the slider, and a screw is rotatably connected to the connecting block. The screw extends upward through the top plates of the first frame and the second frame to the upper part of the top plate, and a nut is fixedly connected to the upper part of the top plate. The screw is threadedly connected to the nut, and a handle is fixedly installed on the top of the screw.

[0009] Furthermore, a guide plate is fixedly mounted on the front side of the first frame of the first roller group.

[0010] Furthermore, the first roller group and the second roller group are separately arranged.

[0011] Furthermore, the angle between the first roller set and the second roller set on the horizontal plane is 0-30 degrees.

[0012] A flaky material separation device of the present invention has the following advantages: the second roller group of the present invention is arranged obliquely relative to the first roller group, so that the material is subjected to an oblique pulling force between the first roller group and the second roller group, so that the material is torn along one end of the score line. Compared with the first roller group and the second roller group arranged in parallel, which directly break the score line by pulling force, the pulling force required by the present application is smaller, and thus the pressure of the first upper roller and the second upper roller on the material is smaller. The present application can separate multiple layers of material, ensure that the material can be separated, and improve the separation efficiency of the material. At the same time, the required pressure is smaller, which avoids indentation of the material caused by excessive pressure and ensures the quality of the material. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to better understand the purpose, structure and function of the present invention, a device for separating sheet materials of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-5 As shown, the sheet material separation device of the present invention comprises a first roller group 1 and a second roller group 2, wherein the second roller group 2 has a faster linear speed than the first roller group 1. When the sheet material 5 passes through the first roller group 1 and enters the second roller group 2, since the linear speed of the second roller group 2 is greater than that of the first roller group 1, a pulling force is generated on the material 5 between the first roller group 1 and the second roller group 2. At the same time, the first roller group 1 and the second roller group 2 form a certain angle on the horizontal plane, that is, one end of the second roller group 2 is closer to the first roller group 1, and the other end is farther from the first roller group 1, that is, the distances between the two ends of the second roller group 2 and the first roller group 1 are different, as shown in FIG. Figure 5As shown, when the score line of the material 5 moves between the first roller group 1 and the second roller group 2, due to the difference in linear speed between the first roller group 1 and the second roller group 2, a pulling force is generated on the material 5. At the same time, the second roller group 2 is inclined relative to the first roller group 1, so that the material 5 on both sides of the score line will be torn apart along one end of the score line, thereby achieving separation of the material 5. Compared with the conventional separation method of directly breaking the material 5 along the score line by pulling force, the separation method of the separation device of the sheet material of the present invention requires less pulling force and less pressure of the roller group on the material 5, so that the separation device of the present invention can separate multiple layers of material 5 at the same time, and the pressure of the first roller group 1 and the second roller group 2 on the material 5 is small, which will not affect the quality of the material 5, thereby improving the separation efficiency of the material 5 and ensuring the processing quality of the material 5.

[0021] The specific first roller group 1 includes a first frame 11, and the first frame 11 includes a bottom plate, a top plate and two side plates. A first lower roller 12 is installed in the lower part of the first frame 11, and both ends of the first lower roller 12 are rotatably connected to the side plates of the first frame 11 through bearings. In addition, one end of the first lower roller 12 extends to the outside of the first frame 11 and is fixedly connected to a first sprocket 14. A first upper roller 13 is installed above the first lower roller 12. Both ends of the first upper roller 13 are installed on the side plates of the first frame 11 through an adjusting component 3. The adjusting component 3 can adjust the position of the first upper roller 13 in the vertical direction, that is, the adjusting component 3 can adjust the distance between the first lower roller 12 and the first upper roller 13. One end of the first upper roller 13 also extends to the outside of the side plate of the first frame 11 and is fixedly connected to the first sprocket 14.

[0022] The second roller group 2 includes a second frame 21, and the second frame 21 includes a bottom plate, a top plate and two side plates. A second lower roller 22 is installed at the lower part of the second frame 21, and both ends of the second lower roller 22 are rotatably connected to the side plates of the second frame 21 through bearings. In addition, one end of the second lower roller 22 extends to the outside of the second frame 21 and is fixedly connected to a second sprocket 24. A second upper roller 23 is installed above the second lower roller 22. Both ends of the second upper roller 23 are installed on the side plates of the second frame 21 through an adjusting component 3. The adjusting component 3 can adjust the position of the second upper roller 23 in the vertical direction, that is, the adjusting component 3 can adjust the distance between the second lower roller 22 and the second upper roller 23. One end of the second upper roller 23 also extends to the outside of the side plate of the second frame 21 and is fixedly connected to a second sprocket 24.

[0023] The driving device of the present application drives the first sprocket 14 and the second sprocket 24 to rotate through a chain, thereby realizing the synchronous rotation of the first upper roller 13 and the first lower roller 12 towards each other, and the synchronous rotation of the second upper roller 23 and the second lower roller 22 towards each other. The linear speed of the second upper roller 23 and the second lower roller 22 of the second roller group 2 of the present invention is greater than the linear speed of the first upper roller 13 and the first lower roller 12 of the first roller group 1. The linear speed difference can be achieved by having the same roller diameter but different sprocket sizes, or by having the same sprocket size but different roller diameters. In this embodiment, the first roller group 1 and the second roller group 2 have the same roller diameter, and the linear speed difference of the first roller group 1 and the second roller group 2 is achieved by first sprockets 14 and second sprockets 24 of different sizes. The diameter of the first sprocket 14 is greater than the diameter of the second sprocket 24, and in order to facilitate transmission, the first lower roller 12 The first sprocket 14 connected to the first upper roller 13 and the second sprocket 24 connected to the second lower roller 22 are located on the same side, while the first sprocket 14 connected to the first upper roller 13 and the second sprocket 24 connected to the second upper roller 23 are located on the other side. The first sprocket 14 and the second sprocket 24 on the same side are connected by the same chain transmission. The use of chain transmission can better adapt to the position adjustment of the first roller group 1 and the second roller group 2. In this embodiment, the first lower roller 12 and the second lower roller 22 are installed at the same position and are on the same horizontal plane, and the upper surfaces of the first lower roller 12 and the second lower roller 22 are consistent with the surface of the conveying channel of the material 5. In addition, in order to facilitate the material 5 to be separated to smoothly enter the middle of the first roller group 1 from the conveying channel, a guide plate 4 is fixedly installed on the front side of the first frame 11 of the first roller group 1, and the guide plate 4 can guide and support the moving material 5.

[0024] The adjusting assembly 3 includes a slider 31, and the two ends of the first upper roller 13 and the second upper roller 23 are rotatably connected to the slider 31 through bearings respectively. At the same time, the slider 31 is slidably connected to the side plates of the first frame 11 and the second frame 21, and the slider 31 can slide up and down along the side plates. A connecting block 32 is fixedly connected to the upper side of the slider 31, and a screw 33 is rotatably connected to the connecting block 32. The screw 33 passes upward through the top plates of the first frame 11 and the second frame 21 and extends to the upper part of the top plate. A nut 34 is fixedly connected to the upper part of the top plate, and the screw 33 is threadedly connected to the nut 34. The rotation of the screw 33 will cause the screw 33 to move up and down relative to the nut 34, thereby driving the connecting block 32 and the slider 31 to move synchronously, thereby realizing the adjustment of the position of the first upper roller 13 and the second upper roller 23. In order to facilitate the adjustment of the position of the first upper roller 13 and the second upper roller 23, a handle 35 is fixedly installed on the top of the screw 33.

[0025] The first roller group 1 and the second roller group 2 of the present invention form a certain angle on the horizontal plane, and the size of the angle can be adjusted, and the size of the angle is 0-30 degrees. In order to facilitate the angle adjustment of the first roller group 1 and the second roller group 2, one end of the first roller group 1 and the second roller group 2 can be connected by a hinge or a rotation connection, so that the second roller group 2 can be rotated on the horizontal plane relative to the first roller group 1 to achieve angle adjustment. Of course, the first roller group 1 and the second roller group 2 can also be separately set. The accompanying drawings in this embodiment show the situation where the first roller group 1 and the second roller group 2 are separately set. The first roller group 1 and the second roller group 2 are separately set, which is more convenient to adjust the position and angle of the first roller group 1 and the second roller group 2, and the distance between the first roller group 1 and the second roller group 2 can also be adjusted. It is more flexible and convenient to use and has better adaptability.

[0026] When in use, the angle between the second roller group 2 and the first roller group 1 is adjusted. The first roller group 1 and the second roller group 2 are respectively fixedly connected to the frame below. At the same time, the distance between the first upper roller 13 and the first lower roller 12 and the distance between the second upper roller 23 and the second lower roller 22 are adjusted by the adjustment component 3 according to the thickness of the material 5 to be separated and the number of layers to be separated. The front and rear sides of the separation device of the present invention are respectively provided with conveying channels. The material 5 to be separated is conveyed to the front side of the first roller group 1 through the conveying channel. The material 5 enters between the first upper roller 13 and the first lower roller 12 of the first roller group 1 through the guide plate 4 provided on the front side of the first roller group 1. The first roller group 1 drives the material 5 to be separated to be transmitted backward, and then the material 5 enters the second roller group 2. Between the second upper roller 23 and the second lower roller 22, since the linear speed of the second upper roller 23 and the second lower roller 22 of the second roller group 2 is greater than the linear speed of the first upper roller 13 and the first lower roller 12 of the first roller group 1, and the second roller group 2 is inclined relative to the first roller group 1, the second roller group 2 will generate an oblique pulling force on the material 5, so that when the score line of the material 5 moves to between the first roller group 1 and the second roller group 2, the material 5 is torn along one end of the score line under the action of the oblique pulling force, and the separated material 5 is transmitted to the rear conveying channel under the action of the second roller group 2 and transported backward, and the remaining material 5 continues to move between the second roller group 2 under the action of the first roller group 1, and the above process is repeated to continuously realize the tearing and separation operation of the material 5.

[0027] In the flaky material separation device of the present invention, due to the inclined setting of the second roller group 2, the material 5 receives an oblique pulling force between the first roller group 1 and the second roller group 2, so that the material 5 is torn along one end of the score line. Compared with the parallel first roller group 1 and the second roller group 2 that directly break the score line by pulling, the pulling force required by the present application is smaller, and thus the required pressure of the first upper roller 13 and the second upper roller 23 on the material 5 is smaller. The present application can separate multiple layers of material 5, thereby improving the separation efficiency of material 5. At the same time, the required pressure is smaller, which avoids indentation of the material 5 caused by excessive pressure, thereby ensuring the quality of the material 5.
