Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bamboo milling machine accessories, in particular to a limiter of a bamboo milling machine. Background Art
[0002] After the bamboo tube is processed into bamboo strips by the automatic large-scale splitting machine, the bamboo strips need to be milled. Since the bamboo strips are relatively soft, there is a limiter at the inlet of the bamboo milling machine or at the entrance of each milling wheel in the milling machine and at the entrance of the feeding wheel. The limiter guides and limits the bamboo strips to prevent the bamboo strips from entering the inlet. The current limiters are divided into two types, namely, limiter A (such as Figure 1 As shown) and limiter B (as shown Figure 2 As shown in the figure, the limiter A is composed of a concave sheet A1, an elastic device A2 and a guide block A3. The upper end surface of the guide block A3 is inclined, and one end is connected to the concave sheet A1 through a shaft pin. The other end of the guide block A3 is supported by the elastic device A2. A feeding channel is formed between the guide block A3 and the end of the concave sheet A1. When the bamboo strips enter, there is sliding friction between the bamboo strips and the feeding channel, and the resistance is large, which affects the smoothness of the movement of the bamboo strips. In addition, the spring of the elastic device A2 will be twisted, causing the guide block A3 to deviate, resulting in the guide and limit The positioning function fails; the limiter B is composed of a base film B1, a trapezoidal guide end B2, a guide strip B3 with an arc-shaped end, and a screw B5 for installing the guide strip B3. A feeding channel is formed between the trapezoidal guide end B2 and the arc-shaped end of the guide strip B3. When the bamboo strips enter, there is sliding friction between the bamboo strips and the feeding channel, and the resistance is relatively large. The guide strip B3 needs to be manually rotated to adjust the position. If the position is not adjusted, the height of the feeding channel is rated, the specifications of the bamboo strips will be limited, and the overall use is inconvenient.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] The utility model provides a technical solution:
[0018] See also Figure 3-4 , a limiter for a bamboo milling machine, comprising a U-shaped frame 1, wherein both sides of the U groove of the U-shaped frame 1 are provided with stepped surfaces 2, and the U groove of the U-shaped frame 1 is provided with two T-shaped sliders 5, both sides of the two T-shaped sliders 5 are stepped, and are respectively slidably embedded with the stepped surfaces 2 on both sides, and one side of the U-shaped frame 1 is provided with two rolling bearings 6, the upper rolling bearing 6 is connected to the upper T-shaped slider 5, and the lower rolling bearing 6 is connected to the lower T-shaped slider 5, the upper T-shaped slider 5 is fastened in the U groove of the U-shaped frame 1, and a spring 9 is provided between the bottom of the lower T-shaped slider 5 and the bottom of the U groove of the U-shaped frame 1;
[0019] The two rolling bearings 6 are used to guide and limit the feeding bamboo strips. When the bamboo strips are moving, they roll and rub against the rolling bearings 6, and the friction force is reduced. The two rolling bearings 6 cause the feeding port to expand. No matter which direction the bamboo strips come from, they will be guided in by the rolling bearings 6. Since the T-shaped slider 5 below is supported by the spring 9, when the bamboo strips are larger in size, the rolling bearings 6 below will be squeezed down to adapt to bamboo strips of different sizes. The stepped surfaces 2 on both sides of the U-groove increase the fit with the T-shaped slider 5 to prevent falling off.
[0020] Among them, since the rolling bearing 6 above is to be fixed in the U-shaped frame 1, a disc 7 is fixed in the inner ring of each rolling bearing 6, and the diameter of the disc 7 is larger than the width of the U-groove of the U-shaped frame 1. The disc 7 is connected to the T-shaped slider 5 through a threaded rod 8. By tightening the threaded rod 8, the disc 7 and the U-shaped frame 1 fit more closely, which will make the upper T-shaped slider 5 fastened in the U-groove of the U-shaped frame 1.
[0021] As the elasticity of the spring 9 gradually decreases, when the elastic force of the spring 9 is insufficient, the threaded rod 11 can be rotated to raise the threaded rod 11, and the threaded rod 8 in the uppermost rolling bearing 6 can be rotated to loosen it, and the rolling bearing 6 is moved downward and tightened after being moved downward. At this time, the distance between the two rolling bearings 6 is unchanged, but the positions are uniformly lowered, but the spring 9 is compressed to increase the elastic force, and the rise of the threaded rod 11 can limit the floating distance of the lower rolling bearing 6 when it is squeezed by the bamboo strips.
[0022] During installation, the stopper is placed on the bracket of the milling machine and fixed by screws penetrating the threaded mounting holes 4 .
[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
