AI Technical Summary
Existing bamboo splitting machines suffer from uneven splitting due to differences in the width, straightness, and thickness of the bamboo strips during the splitting process. This makes it difficult to precisely align the blades, resulting in inconsistent bamboo strip widths and large cumulative errors.
An automatic parallelogram-shaped blade alignment mechanism for bamboo strips is installed in the feeding system of the bamboo splitting machine. The two feeding rollers are synchronized and linked by the parallelogram-shaped connecting rod to achieve automatic blade alignment of the bamboo strips and ensure splitting accuracy.
Automatic blade alignment of bamboo strips was achieved, improving the splitting accuracy, ensuring uniform width of the split bamboo strips, and enhancing product quality.

[0014] Figure 3 This is a schematic diagram of the main structure of the parallelogram-shaped automatic blade setting mechanism for the bamboo strip splitting machine of this utility model. Detailed Implementation
[0015] The structure and features of this utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that various modifications can be made to the embodiments disclosed herein. Therefore, the embodiments disclosed in the specification should not be regarded as limitations on this utility model, but only as examples of embodiments, the purpose of which is to make the features of this utility model obvious.
[0016] like Figure 1 As shown, the principle of automatic blade alignment for bamboo strips in this utility model is as follows: A mechanical linkage mechanism is installed between the two feed rollers 1 of the bamboo splitting machine. This mechanism enables the two feed rollers 1 to move synchronously and symmetrically toward or away from the blade of the bamboo splitting knife 2. To ensure that the center of the bamboo strip 3 passing between the two feed rollers is accurately aligned with the blade of the bamboo splitting knife 2, the two bamboo strips after splitting are of equal width, and the blade of the bamboo splitting knife 2 is located on the perpendicular bisector Y of the line X connecting the axes of the two feed rollers 1.
[0017] like Figure 2 , Figure 3As shown, the aforementioned mechanical linkage mechanism includes a guide plate 4, a parallelogram connecting rod 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 guide plate 4.
[0018] The guide plate 4 is fixed on the frame of the bamboo splitting machine and is located in the middle of the axis of the two feed rollers. At the front and rear of the guide plate 4, a front guide groove 41 and a rear guide groove 42 are respectively opened along the center line of the guide plate. The center line of the front and rear guide grooves is located on the perpendicular bisector of the line connecting the axes of the two feed rollers.
[0019] The four connecting rods constituting the parallelogram linkage 5 are hinged to each other. The symmetrical front and rear hinge shafts 51 are respectively housed in the front guide groove 41 and the rear guide groove 42, and can slide along the front and rear guide grooves. The other two symmetrical left and right hinge shafts 52 are respectively fixed to the feed roller moving sliders 6 located on both sides of the guide plate 4. The feed roller 1 is connected to the feed roller moving slider 6 via bearings 9.
[0020] A spring baffle 8 is fixed on the outer side of each of the two feed rollers 1 and on the frame. 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 Figures 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, increasing the distance between them. The front and rear hinge shafts 51 of the parallelogram connecting rod 5 move along the front and rear guide grooves of the guide plate to the center of the guide plate. The left and right hinge shafts 52 of the parallelogram connecting rod 5 move away from the blade of the splitting knife, thereby driving the two feeding roller moving sliders 6 and the two feeding rollers 1 to move synchronously away from the blade of the splitting knife. Under the action of the parallelogram connecting rod 5, the two feeding rollers 1 will inevitably move synchronously away from the blade of the splitting knife, and the bamboo strip 3 passes through the middle of the two feeding rollers 1. The springs 7 of the two feeding roller moving sliders are compressed. Since the blade of the bamboo 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, the two feeding rollers will not deviate during synchronous movement under the action of the sliding block spring 7 of the two feeding rollers. This ensures that the center of the bamboo strip 3 passing between the two feeding rollers is accurately aligned with the blade of the bamboo splitting knife 2, and the width of the two bamboo strips after splitting is equal.
[0022] After the bamboo strip 3 passes through the middle of the two feeding rollers 1, under the action of the two feeding rollers moving slider spring 7, the two feeding rollers moving slider spring 7 pushes the two feeding rollers moving slider 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; under the action of the parallelogram connecting rod 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 parallelogram linkage mechanism to synchronize the movement of two symmetrically arranged feed rollers, enabling automatic blade alignment and accurate bamboo strip splitting. With its simple structure, this invention can be used to modify the feeding system of a bamboo splitting machine without altering the original mechanical structure, achieving automatic blade alignment and improving 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.
