Description

Technical Field

[0001] This utility model relates to the technical field of gypsum board processing equipment, and in particular to a gypsum board cutting device. Background Technology

[0002] Gypsum board is a commonly used material in interior decoration, mainly used for interior partition walls and ceilings. It has a gypsum core covered by a thick paper outer layer. This material is not only lightweight and strong, but also offers excellent sound and heat insulation, and is highly fire-resistant. A major advantage of gypsum board is its ease of cutting and installation, making it particularly popular in home decoration.

[0003] In the production of gypsum board, stacks of gypsum board are typically placed under them as pallets for easy forklift handling. However, purchasing pallets increases costs, and some defective gypsum board is also generated during production. Recycling these substandard boards is troublesome, requiring multiple processes such as crushing and sieving. Therefore, processing these defective gypsum board boards and using them as pallets to reduce costs has become a viable alternative. The process of processing gypsum board into a pallet substitute includes steps such as applying glue, stacking and resting, cutting, and unloading. Currently, there is no suitable device for cutting stacked gypsum board boards. Utility Model Content

Detailed Implementation

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] As shown in the attached figure, a gypsum board cutting device includes a conveyor frame 1; the conveying direction of the conveyor frame 1 is called the transverse direction, and the direction perpendicular to it in the plane is called the longitudinal direction; shafts 2 are rotatably mounted at both ends of the transverse direction of the conveyor frame 1, and three sets of belt conveyors 3 are spaced apart on the two shafts 2; a support plate 4 corresponding to the belt conveyor 3 is provided on the conveyor frame 1, and the support plate 4 is used to support the upper conveyor belt surface of the belt conveyor 3 to ensure effective support and conveying of the gypsum board during conveying; a reduction motor 5 for driving one of the shafts 2 is provided on the conveyor frame 1; a lifting frame 6 is provided below the belt conveyor 3, and the lifting frame 6 is connected by... The lifting cylinder 7 is connected to the conveyor frame 1; the lifting cylinder 7 raises and lowers the lifting frame 6; the lifting frame 6 is equipped with multiple sets of lifting members 8 that can extend upwards to the upper end of the belt conveyor 3. When the piston rod of the lifting cylinder 7 retracts, the upper end of the lifting member 8 is lower than the upper conveying surface of the belt conveyor 3, and the gypsum board can be conveyed normally. When cutting is required, the belt conveyor 3 conveys the gypsum board to the corresponding cutting position and then stops. At this time, the piston rod of the lifting cylinder 7 extends, pushing the lifting member 8 upwards. The upper end of the lifting member 8 slightly exceeds the conveying surface of the belt conveyor 3, simultaneously lifting the gypsum board so that the lower end of the gypsum board is higher than the conveying surface of the belt conveyor 3; it also includes a cross The cutting frame 9 passes through the conveyor frame 1. A longitudinally movable frame 10 is guided and connected to the cutting frame 9. The guide connection can employ common guide structures such as dovetail grooves. A movable shaft 11 is rotatably mounted on the movable frame 10. Two parallel racks 12 are mounted on the cutting frame 9. Gears 13, which mesh with the racks 12, are fixedly connected to the movable shaft 11. A second reduction motor 14 is mounted on the cutting frame 9. The second reduction motor 14 is driven by the movable shaft 11 through a second transmission mechanism 15. The second transmission mechanism 15 can be a belt drive or a chain drive. The second reduction motor 14 drives the movable shaft 11 to rotate, thereby rotating the gears 13 on it. The gears 14 mesh with… When the rack 12 engages, it can drive the moving frame 10 to move along the cutting frame 9. Controlling the forward and reverse rotation of the reduction motor 15 can make the moving frame 10 move backward. The moving frame 10 is rotatably mounted on the shaft 16, and four cutting discs 17 are fixedly connected at equal intervals on the shaft 16. The moving frame 10 is equipped with a reduction motor 18, which is driven by the shaft 16 through a transmission mechanism 19. The transmission mechanism 19 can be a common belt drive mechanism, etc. The reduction motor 18 drives the shaft 16 to rotate at high speed, thereby rotating the cutting discs 17 to cut the plasterboard. The lifting member 8 has a gap for the cutting discs 17 to pass through.

[0023] As a further improvement to this example, guide rollers 20 are rotatably installed on both sides of the conveyor frame 1, which can ensure that the input angle of the gypsum board does not deviate, and can also limit the gypsum board to a certain extent during cutting.

[0024] As a further improvement to this example, multiple portal frames 21 are spaced apart on the conveyor frame 1 above the lifting frame 6. The portal frames 21 are arranged in the longitudinal direction, and the width of the portal frame 21 is greater than the width of the gypsum board. After the gypsum board is conveyed in, it passes under the portal frame 21 and is clamped by the lifting component 8 to further improve the stability of the cutting.

[0025] As a specific technical solution in this example, the belt conveyor 3 includes a pulley 31 fixedly connected to shaft 2, and a conveyor belt 32 meshing with the pulley 31. Preferably, a toothed belt mechanism with reliable transmission is adopted to improve the accuracy of gypsum board conveying and positioning. The input length of the gypsum board can be controlled by existing technologies such as photoelectric switches, which will not be elaborated further.

[0026] As a further improvement to this example, the lifting member 8 includes a plurality of lifting masts 81 spaced apart in the longitudinal direction. The lifting masts 81 have gaps between them for the cutting disc 17 and the belt conveyor 3 to pass through. Obviously, the lifting member 8 can also adopt other suitable structures, such as opening deep grooves on the integral lifting member 8 to allow the cutting disc 17 and the belt conveyor 3 to pass through.

[0027] Obviously, in order to reduce dust, a dust collection hood (not shown in the figure) can also be installed on the mobile frame 10.

[0028] The work process is as follows:

[0029] First, the gypsum board is conveyed laterally by a belt conveyor 3, which is driven by a geared motor 5 mounted on a conveyor frame 1. To ensure effective support for the gypsum board during conveying, a support plate 4 corresponding to the belt conveyor 3 is installed on the conveyor frame 1 to support the conveyor belt 32. When the gypsum board needs to be cut, the belt conveyor 3 will transport the gypsum board to the designated cutting position and then stop. At this time, the lifting cylinder 7 pushes the lifting frame 6 connected to it to rise, and the lifting component 8 on the lifting frame 6 rises accordingly, slightly lifting the gypsum board away from the upper surface of the belt conveyor 3. The shaft 16, which is rotatably mounted on the movable frame 10, is equipped with four equally spaced cutting discs 17. The lower edge of the cutting discs 17 is slightly higher than the conveying surface of the belt conveyor 3 but not higher than the lower surface of the lifted gypsum board to ensure complete cutting of the gypsum board. The cutting discs 17 are driven to rotate at high speed by the geared motor 18. Then, the movable frame 10, which is mounted on the cutting frame 9, moves longitudinally by the geared motor 14, gear 13 and rack 12 to complete the cutting of the gypsum board. After the cutting is completed, the geared motor 14 drives the cutting frame 9 to reset in the reverse direction, the piston rod of the lifting cylinder 7 retracts, and the cut gypsum board comes into contact with the belt conveyor 3. The belt conveyor 3 starts again to transport the cut gypsum board forward to a cutting position, and the above steps are repeated for the next round of cutting.

These omitted parts all fall within the scope of existing technology, and those skilled in the art can fully implement the design and manufacture of these parts based on their professional knowledge and existing technical materials. Therefore, they will not be described in detail here.

[0031] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
