Description
Technical Field
[0001] The utility model relates to the technical field of bamboo weaving painting processing, in particular to a bamboo filament cutting device with adjustable thickness. Background Art
[0002] Bamboo weaving painting is a traditional Chinese handicraft that was once listed as a royal tribute. It is both practical and a decorative item that beautifies life. Bamboo weaving painting is done on finely woven bamboo silk roller curtains. It usually uses traditional Chinese painting techniques and selects bamboo with a tough texture and uniform thickness, such as moso bamboo and cycad bamboo. The bamboo can be processed, such as peeling, splitting, dyeing, etc., to meet different creative needs.
[0003] The inventors found the following problems in the prior art during the process of realizing the present invention: 1. Cutting bamboo into strips is a delicate job. When cutting bamboo strips, it is necessary to ensure that the knife is sharp so that uniform bamboo strips can be cut. When cutting bamboo strips, the existing blade and knife adopt an integrated structure, which can only cut a single bamboo into strips. Bamboo strip cutting requires the use of another device, resulting in the two devices occupying more production site space. For companies with limited space, it will affect the production layout and work efficiency. Operators need to be familiar with and master the operation methods and maintenance skills of two different devices, which increases training costs. and operation difficulty; 2. To cut bamboo into strips, the bamboo needs to be hit against the cutting knife. If the feed speed is too fast, the cutting force that the blade instantly bears will increase greatly, causing the blade to deform, chip, or even break. When encountering bamboo with particularly hard material, greater cutting force is required for cutting, which will cause greater pressure on the blade and easily cause damage to the blade. When the blade is worn or damaged, since the blade and the fixed blade assembly are integrated, they need to be replaced as a whole, which increases the cost of later maintenance and replacement. The integrated design may require the disassembly and installation of the entire assembly during maintenance, which is complicated to operate and consumes time and effort. Utility Model Content

When the blade is worn or damaged, since the blade and the fixed blade assembly are integrated, they need to be replaced as a whole, which requires replacement as a whole, resulting in increased maintenance and replacement costs in the future. In order to achieve the above purpose, the present invention provides the following technical solutions: a bamboo filament cutting device with adjustable thickness, comprising a slide rail, a support plate mounted on one side of the slide rail by screws, a support seat mounted on the top of the slide rail by screws, a push plate fitted inside the slide rail, and a positioning rod welded inside the push plate;

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] In the utility model, two devices were originally required to cut bamboo strips and bamboo strips. The improved device can cut bamboo strips and bamboo strips at the same time, reducing the space occupied by the equipment. For enterprises with limited space, it optimizes the production layout and improves space utilization. Operators do not need to switch operations between the two devices, which reduces the operation steps and time and improves work efficiency.

[0015] In the utility model, the servo motor drives the moving block to move through the sprocket and the chain, and the moving block pushes the bamboo closer to the blade. Since the control system can accurately control the speed and direction of the servo motor, the precise adjustment of the bamboo feed speed can be achieved to avoid the blade being deformed, chipped or broken due to the instantaneous excessive cutting force caused by the feed speed being too fast. The position sensors and springs at both ends of the slide rod can buffer the moving block, further ensuring the stability of the feed speed and reducing the impact on the blade. The blade is fixed by the fixing plate and the connecting plate, and can be clamped or loosened and adjusted by the first threaded screw and the first nut, the second threaded screw and the second nut. This fixing method enables the blade to better withstand the cutting force when facing bamboos of different materials. When encountering bamboos of particularly hard material, the fixing strength of the blade can be enhanced by adjusting the nut, reducing the possibility of the blade being damaged due to greater pressure.

[0031] The use method and advantages of the utility model: When the thickness-adjustable bamboo filament cutting device is used, the working process is as follows:
[0032] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, first, when the system is started, the servo motor 301 and the position sensor located in the spring 306 are initialized and set to determine the initial position and movement direction of the moving block 303. The control system sends a command to make the servo motor 301 rotate at a specific speed and direction. The rear output shaft of the servo motor 301 is installed on the rotating shaft of the sprocket 304 through bolts, so that the sprocket 304 forms a rotating structure through the servo motor 301. The two sprockets 304 are respectively attached to the two ends of the chain 302. When the sprocket 304 rotates, it drives the chain 302 to move. The moving block 303 forms a horizontal sliding structure with the slide bar 305 through the chain 302. Therefore, when the chain 302 moves, it drives the moving block 303 to slide horizontally on the slide bar 305. A push plate 5 is installed, and a positioning rod 4 is provided on the push plate 5, so that the push plate 5 moves horizontally through the bamboo, and the push plate 5 pushes the bamboo to move in the direction of the blade 208. The positioning rod 4 on the push plate 5 and the positioning rod 4 welded behind its two connecting plates 205 are horizontally mirrored, ensuring that the direction in which the push plate 5 pushes the bamboo is consistent with the cutting direction of the blade 208. When the moving block 303 moves to one end of the slide bar 305 and triggers the position sensor sensing piece in the spring 306, the position sensor transmits a signal to the control system. After receiving the signal, the control system immediately changes the rotation direction of the servo motor 301. For example, if the servo motor 301 originally rotates forward, the control system reverses the servo motor 301 at this time, and the reversed servo motor 301 drives the chain 3 through the sprocket 304. 02 reverse movement, so that the moving block 303 moves linearly in the opposite direction, repeating the above process, so that the moving block 303 continuously performs linear reciprocating motion between two specific positions, and the spring 306 plays a buffering role on the moving block 303 that moves, so that the moving block 303 fits the position sensor and realizes linear reciprocating motion. During the bamboo filament cutting process, one side of the blade 208 is fixed by two connecting plates 205, and the other side is fixed by two fixing plates 204. One fixing plate 204 is welded with a first threaded screw 201, and the first threaded screw 201 is plugged into the second fixing plate 204. The first nut 202 fits on one side of the second fixing plate 204, and the first threaded screw 201 and the first nut 202 are distributed in a ring around the axis. By rotating the first The nut 202 can adjust the distance between the two fixing plates 204, thereby clamping or loosening one end of the blade 208, and realizing the fixation and adjustment of the blade 208 in one direction. A plurality of slots 203 are provided on the rear edge of one connecting plate 205, which are distributed in a ring around the axis of one connecting plate 205. The internal structural dimensions of the slots 203 are consistent with the external structural dimensions of the blade 208. The blade 208 is inserted into the slots 203 to achieve preliminary positioning. A second threaded screw 207 is inserted in the middle of one connecting plate 205. The external structural dimensions of the second threaded screw 207 are consistent with the external structural dimensions of the second nut 206, and a second threaded screw 207 is welded to the front of the second connecting plate 205. By rotating the second nut 206,The distance between the two connecting plates 205 can be adjusted to tighten or loosen the other side of the blade 208, further securing the blade 208. Since the blades 208 are secured with slots 203, the number of blades 208 is even, and the blades 208 can be removed one after another. The thickness of the bamboo to be cut can be adjusted, and both shredding and slicing can be achieved. The adjustable spacing between the blades 208 facilitates cutting, allowing precise cutting of each bamboo strand, ensuring uniform size and providing high-quality raw materials for the subsequent production of bamboo products.
