AI Technical Summary
Existing bamboo splitting machines often result in uneven splitting due to differences in the width, straightness, and thickness of the bamboo strips. This makes precise blade alignment difficult, leading to inconsistent bamboo strip widths and significant cumulative errors.
An automatic blade-aligning mechanism with a gear and rack is installed in the feeding system of the bamboo splitting machine. Through the meshing and linkage of the central gear and the synchronous rack, the synchronous and symmetrical movement of the two feeding rollers is achieved, ensuring that the center of the bamboo strip is accurately aligned with the blade of the bamboo splitting machine.
Automatic blade alignment of bamboo strips was achieved, improving the splitting accuracy and ensuring that the width of the split bamboo strips is uniform, thus enhancing the processing quality of the bamboo splitting machine.

[0015] The structure and features of the present application will be described in detail below in combination with the drawings and examples. It should be noted that various modifications can be made to the examples disclosed herein, therefore, the examples disclosed in the specification should not be regarded as limiting the present application, but only as examples, and the purpose is to make the features of the present application obvious.
[0016] As shown in the drawings, Fig. 1 The principle of automatically aligning the cutter of the bamboo splitting machine is that a mechanical linkage mechanism is installed between the two feeding rollers 1 of the bamboo splitting machine, and the two feeding rollers 1 are synchronously linked through the mechanical linkage mechanism, and synchronously and symmetrically move towards the cutting edge of the bamboo splitting knife 2 or away from the cutting edge of the bamboo splitting knife. In order to ensure that the center of the bamboo 3 passing between the two feeding rollers is accurately aligned with the cutting edge of the bamboo splitting knife 2, the width of the two bamboo pieces after splitting is equal, and the cutting edge of the bamboo splitting knife 2 is located on the perpendicular bisector Y of the line X connecting the axes of the two feeding rollers 1.
[0017] As shown in the drawings, Fig. 2 , Fig. 3As shown, the aforementioned mechanical linkage mechanism includes a central gear 4, two synchronous racks 5, two feed roller sliding blocks 6, two feed roller sliding block springs 7, and two spring baffles 8. The two feed rollers 1, the two feed roller sliding blocks 6, the two feed roller sliding block springs 7, and the two spring baffles 8 are arranged on both sides of the central gear 4.
[0018] The central gear 4 is mounted on the frame of the bamboo splitting machine via a gear bearing, located in the middle of the axis of the two feed rollers 1, and the axis of the central gear is located at the midpoint of the line connecting the axes of the two feed rollers.
[0019] Two synchronous racks 5 are located on both sides of the central gear 4 and mesh with it. Two feed roller sliders 6 are fixed to the ends of the two synchronous racks 5 by connecting bolts 9. Feed rollers 1 are connected to the feed roller sliders 6 via bearings 10 and pins 11. When the two feed rollers 1 and their connected feed roller sliders 6 move toward / away from the cutting edge of the bamboo slicing knife, the two feed rollers 1 will move synchronously due to the meshing of the central gear 4 with the two synchronous racks 5.
[0020] A spring baffle 8 is fixed on the outer side of each of the two feed rollers and on the frame of the bamboo splitting machine. A feed roller moving slider spring 7 is provided between each spring baffle 8 and the outer wall of the feed roller moving slider 6.
[0021] like Figs. 1-3 As shown, during the splitting of bamboo strips, the bamboo strip 3 is pushed forward and passes between the two feeding rollers 1. Under the pressure of the bamboo strip 3, the two feeding rollers 1 move away from the blade of the splitting knife, and the distance between the two feeding rollers 1 increases. During the process of the two feeding rollers 1 moving away from the blade of the splitting knife, the feeding roller 1 drives the feeding roller moving slider 6 connected to it and the synchronous rack 5 connected to the feeding roller moving slider 6 to move synchronously away from the blade of the splitting knife. Constrained by the meshing of the central gear 4 and the two synchronous racks 5, the two feeding rollers 1 must move synchronously away from the blade of the splitting knife, the bamboo strip 3 passes through the middle of the two feeding rollers 1, and the spring 7 of the two feeding roller moving slider is compressed. Since the two feeding rollers 1 are symmetrically arranged on both sides of the splitting knife, the blade of the splitting knife is located on the perpendicular bisector of the line connecting the axes of the two feeding rollers, and the two feeding rollers move synchronously, under the action of the sliding block spring 7 of the two feeding rollers, the two feeding rollers will not deviate during synchronous movement, so that the center of the bamboo strip 3 passing between the two feeding rollers is accurately aligned with the blade of the splitting knife 2, and the width of the two bamboo strips after splitting is equal.
[0022] After the bamboo strip 3 passes between the two feeding rollers 1, under the action of the two feeding roller moving slider springs 7, the two feeding roller moving slider springs 7 push the two feeding roller moving sliders 6 to move synchronously towards the direction of the bamboo splitting knife blade, which in turn drives the two feeding rollers 1 to move synchronously towards the direction of the bamboo splitting knife blade. Constrained by the meshing of the central gear 4 and the two synchronous racks 5, the two feeding rollers 1 will inevitably move synchronously towards the direction of the bamboo splitting knife blade.
[0023] Repeat the above process to achieve the automatic blade alignment function of the bamboo splitting machine.
[0024] This invention utilizes a mechanical gear and rack automatic blade-aligning mechanism to synchronize the interlocking movement of two symmetrically arranged feeding rollers, achieving automatic blade alignment and accurate bamboo strip splitting. This invention has a simple structure and, without altering the original mechanical structure, can be used to modify the feeding system of a bamboo splitting machine to achieve automatic blade alignment and improve the accuracy of bamboo strip splitting.
[0025] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
