Description

A bamboo fiber cutting device Technical Field

[0001] This utility model belongs to the technical field of cutting devices, specifically a bamboo fiber cutting device. Background Technology

[0002] Bamboo fiberboard is a type of board made from bamboo fiber. It features excellent water absorption, breathability, and wear resistance, and also performs well in antibacterial, moth-repellent, bacteriostatic, odor-resistant, and UV-resistant properties. Bamboo fiberboard is made by pulverizing bamboo and other plant materials. It is mainly used for flooring and wall decoration, and has high environmental performance.

[0003] Currently, bamboo fiberboard is extruded using a plasticizer. After molding, it needs to be cut using a cutting device to obtain the required length. To avoid cutting dust, existing bamboo fiberboard cutting machines are used. These machines mainly work by first pressing the two sides of the cutting area with a cylinder, and then using a moving structure to drive the blade to cut the bamboo fiberboard. Examples include the dust-free cutting machine produced by Zhangjiagang Kangju Machinery and the dust-free cutting machine disclosed in patent CN208773666U. In actual use, the applicant has found that the cutting blades of the above-mentioned existing dust-free cutting machines wear down with each use and need to be replaced frequently. However, the cutting equipment is located between the pressing structures on the front and back sides and is set up within the mounting frame. Therefore, the space for personnel to operate is small during actual replacement operations, increasing the difficulty of blade replacement and reducing maintenance efficiency. To solve the above-mentioned problems, a bamboo fiber cutting device is proposed. Summary of the Invention

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] The following will describe in detail an embodiment of the present invention, a bamboo fiber cutting device, with reference to Figures 1-3.

[0018] Example:

[0019] The present invention provides a bamboo fiber cutting device, as shown in Figures 1 to 3, comprising a base plate 1, two vertical frames 2 fixedly connected to the base plate 1, a rear side plate 4 fixedly installed at the rear of the two vertical frames 2, two slide rails 5 fixedly connected to the rear side plate 4, a slider 6 slidably connected to the slide rails 5, a mounting frame 7 fixedly installed on the slider 6, a reduction motor 8 fixedly installed on the mounting frame 7, a gear 9 fixedly installed on the output shaft of the reduction motor 8, a rack 10 fixedly installed on the rear side plate 4, the gear 9 and the rack 10 meshing together, a cylinder 11 fixedly installed on the mounting frame 7, a lifting frame 12 fixedly installed on the piston rod of the cylinder 11, a blade holder 17 provided on the lifting frame 12, and multiple bamboo fiberboard blades 18 installed on the blade holder 17. This structure drives the gear 9 to rotate through the reduction motor 8, and the gear 9, in conjunction with the rack 10, drives the mounting frame 7 to move on the slide rails 5 via the slider 6, thereby driving the blades 18 on the blade holder 17 to move, thus cutting the bamboo fiberboard.

[0020] After each cut is completed, the cylinder 11 is started to lift the lifting frame 12, thereby raising the height of the blade 18. Then, the reduction motor 8 is started in the opposite direction to drive the blade 18 back to its original position. Then, the cylinder 11 is started to move the blade 18 down, so as to facilitate the next cut.

[0021] Referring to Figures 1 to 3, the vertical frame 2 is fitted with an opening slot 3. A second cylinder 13 is fixedly installed on the lifting frame 12. A slide 14 is fixedly installed on the piston rod of the second cylinder 13. A guide block 15 is installed on the back of the slide 14. A guide rail 16 is fixedly installed on the lower part of the lifting frame 12. The guide block 15 and the guide rail 16 are slidably connected. The blade holder 17 is installed on the slide 14. In this structure, when the blade 18 needs to be replaced, the blade 18 is first moved to the cutting end position by the reduction motor 8. Then, the first cylinder 11 is started to drive the lifting frame 12 to rise. Then, the second cylinder 13 is started to push the slide 14. The slide 14 slides on the guide rail 16 on the lifting frame 12 through the guide block 15, thereby allowing the blade holder 17 on the slide 14 to pass through the opening slot 3 on the vertical frame 2. This moves the blade holder 17 outside the equipment frame, giving personnel the final space to perform replacement and adjustment work during maintenance. This avoids increasing the difficulty of replacement and adjustment due to limited space and makes the equipment more convenient to use.

[0022] Referring to Figures 1 to 3, the base plate 1 is provided with a strip hole 19 corresponding to the moving position of the blade 18. With this structure, the blade 18 can extend into the strip hole 19, thereby facilitating cutting by the blade 18.

[0023] Referring to Figures 1 to 3, front side plates 20 are fixedly installed on the front sides of the two vertical frames 2. Right-angle plates 21 are fixedly installed on both the front side plates 20 and the rear side plates 4. Two cylinders 22 are fixedly connected to the right-angle plates 21. Pressure strips 23 are fixedly installed on the piston rods of the cylinders 22. In this structure, the cylinders 22 drive the pressure strips 23 to move down, thereby pressing down on the front and rear sides of the bamboo fiberboard cutting position, thus ensuring positional stability during cutting.

[0024] Referring to Figures 1 to 3, two guide blocks 24 are fixedly installed on the back of the lifting frame 12, and two guide rails 25 are fixedly installed on the lifting frame 12. The guide blocks 24 are slidably connected to the guide rails 25. This structure uses the guide blocks 24 to slide on the guide rails 25, thereby guiding the movement of the lifting frame 12.

[0025] Referring to Figures 1 to 3, one end of the slide rail 5 is provided with a baffle 26 fixedly installed on the lifting frame 12. With this structure, one end of the slide 14 can abut against the baffle 26, thereby blocking the slide 14 during cutting, thereby reducing the thrust on the cylinder 13 and protecting the cylinder 13.

[0026] The implementation principle of a bamboo fiber cutting device according to an embodiment of this application is as follows: In use, the gear 9 is driven to rotate by the reduction motor 8. The gear 9, in conjunction with the rack 10, drives the mounting frame 7 to move on the slide rail 5 via the slider 6, thereby driving the blade 18 on the blade holder 17 to move, thereby cutting the bamboo fiber board. After each cut is completed, the cylinder 11 is started to drive the lifting frame 12 to rise, thereby raising the height of the blade 18. Then, the reduction motor 8 is started in the opposite direction to drive the blade 18 back to its original position. Then, the cylinder 11 is started to drive the blade 18 to move down, thus facilitating the next cut.

[0027] When the blade 18 needs to be replaced, the blade 18 is first moved to the cutting end position by the reduction motor 8. Then, the cylinder 11 is started to drive the lifting frame 12 to rise. Then, the cylinder 213 is started to push the slide 14. The slide 14 slides on the guide rail 16 on the lifting frame 12 through the guide block 15, so that the blade holder 17 on the slide 14 passes through the opening slot 3 on the vertical frame 2, thereby moving the blade holder 17 outside the equipment frame. Then, the personnel have the final space to carry out the replacement and adjustment work during maintenance, avoiding the increase in replacement and adjustment difficulty due to the narrow space, and making the equipment more convenient to use.

The aforementioned geared motor 8, cylinder 11, cylinder 213 and cylinder 32 are all externally connected to the PLC control terminal.
