Description

Technical Field

[0001] The utility model relates to the technical field of accessories of a bamboo strip milling machine, in particular to a tool bending angle adjustable structure of a bamboo milling machine. Background Art

[0002] A bamboo milling machine is a device for processing the bamboo green surface and bamboo yellow surface of bamboo. As Figure 1 shown, the milling machine is provided with a feeding roller for bamboo strips, a milling cutter, and a bending angle on one side of the cutter. Usually, there are two milling cutters, upper and lower, and two bending angles on the upper and lower sides. The two bending angles clamp the bamboo strip, so that the cutter can mill the bamboo strip. During milling, the upper cutter is installed by screws and needs to be manually adjusted up and down. The lower cutter is installed by an elastic support member and will shift up and down and left and right when the bamboo strip specifications change. Currently, the two upper and lower bending angles are installed by threaded rods or screws (when debugging the upper bending angle, it moves up and down, and when adjusting the lower bending angle, it moves clockwise or counterclockwise. The lower bending angle is mainly installed by using a disc 19 and screws). Especially for the lower bending angle, when the lower cutter shifts up and down and left and right, it is necessary to manually adjust this bending angle immediately, and the machine needs to be stopped during adjustment, resulting in troublesome work and affecting the processing efficiency.

[0003] Therefore, in order to correct the above defects, we propose a tool bending angle adjustable structure of a bamboo milling machine. Content of the Utility Model

[0004] The technical problem solved by the utility model is to propose a tool bending angle adjustable structure of a bamboo milling machine.

[0005] To achieve the above object, the utility model provides the following technical solution: A tool bending angle adjustable structure of a bamboo milling machine, including a bending angle, further including a balance rod, a carrier plate, and a fixing plate. The bending angle is installed at one end of the balance rod. A bearing one is penetrated through the middle of the balance rod, and this bearing one is installed on the carrier plate through a tightening threaded rod. A counterweight plate is fixed at the other end of the balance rod. A counterweight block is placed on the upper end of the counterweight plate. A limiting rod is fixed at the bottom of the counterweight plate. The bottom of the limiting rod movably penetrates through the fixing plate and is installed with a gasket and a nut one. There is a spring between the gasket and the bottom of the fixing plate, and this spring is sleeved outside the limiting rod.

[0006] Further, a horizontal waist slot two is provided on the front surface of the carrier plate, and a chute is provided on the back surface of the carrier plate. The chute communicates with the waist slot two, and a slider slides in the chute. The tightening threaded rod penetrates through the waist slot two and is connected to the slider.

[0007] Further, both the chute and the slider are of a T-shaped structure.

[0008] Further, a second nut is welded to one side of the carrier plate. A safety threaded rod is threadedly connected inside the second nut. One end of the safety threaded rod penetrates into the chute and is fixed with a pull rod. A second bearing is installed on the side of the slider close to the pull rod, and the pull rod is connected to the second bearing.

[0009] Further, the limiting rod is vertically structured. A first kidney-shaped groove is formed on the fixing plate, and the bottom of the limiting rod penetrates through the first kidney-shaped groove on the fixing plate.

[0010] Further, the limiting rod is arc-shaped. The movement path of the limiting rod is circular, and the center point of the circle coincides with the center point of the first bearing.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The device uses an elastic balance support to support the lower bend angle. When the lower tool moves up and down, the lower bend angle can automatically move clockwise or counterclockwise without manual adjustment, making it more convenient to use and without stopping the machine, which can improve the processing effect. At the same time, when the lower tool moves left and right, the lower bend angle can move left and right accordingly to prevent the gap between the tool and the bend angle from becoming smaller or having no gap to hinder the normal operation of the tool.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] 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.

[0021] The utility model provides a technical solution:

[0022] See also Figure 2-5 A tool angle adjustable structure of a bamboo milling machine includes an angle 1, a balance bar 2, a carrier plate 3, and a fixing plate 6. The angle 1 is an angle on the milling machine 18 that needs to move clockwise or counterclockwise. The structure of the angle 1 is known to those skilled in the art. Figure 1 As shown, the structure of the bend 1 is not described in detail in this case. The carrier plate 3 is fixed to the milling machine 18 and is used to carry the balance bar 2. The fixing plate 6 is also fixed to the milling machine 18. The bend 1 is installed at one end of the balance bar 2. A bearing 4 runs through the middle of the balance bar 2. The bearing 4 is installed on the carrier plate 3 by tightening the threaded rod 5. A counterweight plate 7 is fixed to the other end of the balance bar 2. A counterweight block 10 is placed on the upper end of the counterweight plate 7. A limit rod 8 is fixed to the bottom of the counterweight plate 7. The bottom of the limit rod 8 runs through the fixing plate 6 and is installed with a gasket and a nut. A spring 9 is provided between the gasket and the bottom of the fixing plate 6. The spring 9 is sleeved on the outside of the limit rod 8. When When the bamboo strip becomes thicker, the bend 1 and the tool corresponding to the bend 1 are pressed down together. At this time, the bend 1 is subjected to pressure, driving the balance bar 2 to rotate clockwise through the bearing 1 4. After the rotation, the bend 1 is subjected to the reaction force of the spring 9, so that the upper end of the bend 1 will support the bamboo strip, and the role of the limit rod 8 is to prevent the movement path of the bend 1 or the balance bar 2 from deviating, and the role of the counterweight plate 7 and the counterweight block 10 is to increase the gravity of one end of the balance bar 2, which helps to generate a reaction force on the bend 1. When the bamboo strip becomes thinner, the pressure on the upper end of the bend 1 is reduced or disappears, and the spring 8 will cause the bend 1 and the balance bar 2 to reset;

[0023] In the above description, since the balance bar 2 is rotating, the limit rod 8 also moves along the circular motion route of the bend 1. In the case where the limit rod 8 is a vertical rod, a waist groove 1 needs to be opened on the fixed plate 6. The bottom of the limit rod 8 passes through the waist groove 1 on the fixed plate 6. The waist groove 1 can meet the circular route movement of the limit rod 8. The limit rod 8 can also be set to an arc shape, consistent with the circular route. The movement route of the limit rod 8 is annular, and the circular point coincides with the circular point of the bearing 1 4, which will not hinder the rotation of the balance bar 2.

[0024] In addition, when the tool is offset left or right and the position of the bend angle 1 remains unchanged, the clearance between the tool and the bend angle 1 will change:

[0025] When the clearance is large, the bend angle 1 cannot press against the bamboo strip beside the tool, or the contact point between the bend angle 1 and the bamboo strip is far from the contact point between the tool and the bamboo strip. The restraining force on the part of the bamboo strip in contact with the tool is reduced, which is not conducive to better milling of the tool;

[0026] When the clearance is small, the bamboo chips generated during processing will be blocked between the tool and the bend angle 1, affecting the rotation of the tool and preventing the subsequent bamboo chips from falling;

[0027] When there is no clearance, it will directly hinder the rotation of the tool;

[0028] Therefore, based on the above, it is necessary to set the bend angle 1 to be movable left and right. Specifically, the front of the carrier plate 3 has a transverse waist groove II 11, the back of the carrier plate 3 has a T-shaped sliding groove 12, the sliding groove 12 communicates with the waist groove II 11, and a T-shaped slider 13 slides in the sliding groove 12. The tightening threaded rod 5 passes through the waist groove II 11 and is connected to the slider 13. A nut II 15 is welded to one side of the carrier plate 3. A safety threaded rod 16 is threadedly connected to the nut II 15. One end of the safety threaded rod 16 penetrates into the sliding groove 12 and is fixed with a pull rod 17. A bearing II 14 is installed on the side of the slider 13 close to the pull rod 17, and the pull rod 17 is connected to the bearing II 14;

[0029] When the tightening threaded rod 5 is rotated, the bearing I 4 and the carrier plate 3 are loosened, and the positions of the bearing I 4 and the balance rod 2 can be adjusted left and right. At the same time, the slider 13 will slide in the sliding groove 12. To ensure stability, the safety threaded rod 16 is added. After the tightening threaded rod 5 is rotated, the safety threaded rod 16 needs to be rotated. The screwing in and out of the safety threaded rod 16 on the nut II 15 will drive the forward and backward movement of the slider 13, thereby adjusting the positions of the bearing I 4 and the balance rod 2.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
