DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the embodiments of the present application will be described in detail below with reference to the drawings, but the embodiments described in the present application are only some of the embodiments of the present application, not all the embodiments.

[0022] As shown in the drawings, Figures 1-4 The present embodiment provides a bamboo pulp raw material processing knife group arranged at one end of a bamboo pole conveying device discharge port, used for ejecting the inner bamboo joints of the bamboo pole, and simultaneously cutting the bamboo pole. The bamboo pulp raw material processing knife group comprises an aggregate table 10 and a knife group 20. As shown in the drawings, Figure 1 The number of the knife group 20 can be adjusted according to the number of the bamboo poles output from the discharge end of the bamboo pole conveying device, so that the knife group 20 corresponds to the output bamboo poles one by one. In the present example, Figure 2 only one knife group 20 is shown.

[0023] As shown in the drawings, Figure 2 , Figure 4 The aggregate table 10 has a rectangular structure, the length direction of which is consistent with the incoming direction of the bamboo pole 1. Supports 11 are arranged on both sides of the aggregate table 10. The upper end of each support 11 is provided with a rectangular hole 111, and the lower end of each support 11 is provided with a mounting plate 112. Strip-shaped grooves 113 are recessed on both sides of the length direction of the rectangular hole 111.

[0024] A cam assembly 12 is arranged in the rectangular hole 111. The cam assembly 12 comprises an elliptical cam 121. Convex edges 123 are outwardly protrudingly arranged on both sides of the outer periphery of the cam 121. A U-shaped seat 124 is arranged on one side of the cam 121, and the opening of the U-shaped seat 124 faces the direction in which the cam 121 is arranged. Rollers 125 are vertically arranged on the inner side of one end of both arms of the U-shaped seat 124. The rollers 125 are in rolling connection with the inner side of the convex edges 123 on both sides of the cam 121. Rollers 126 are arranged at both ends of the horizontal part of the U-shaped seat 124, and the rollers 126 are in rolling connection with the strip-shaped grooves 113. A reciprocating rod 122 is arranged at the center of the horizontal part of the U-shaped seat 124. One end of the reciprocating rod 122 penetrates through the rectangular hole 111 and extends to the outer end of the support 11.

[0025] The mounting plate 112 is provided with a synchronous belt assembly 13, which includes a motor 131. The motor 131 is mounted on the top surface of the mounting plate 112. The output end of the motor 131 is provided with a drive shaft 132. The drive shaft 132 is provided with a first synchronous pulley 133. A synchronous belt 134 is sleeved on the first synchronous pulley 133. A second synchronous pulley 135 is provided at the upper end of the synchronous belt 134. The second synchronous pulley 135 is coaxially located on one side of the cam 121 and is used to drive the cam 121 to rotate eccentrically.

[0026] like Figure 3 As shown, the blade assembly 20 includes a crossbar 21, a cross seat 22, and a cutting blade 23. Both ends of one side of the crossbar 21 are connected to one end of the reciprocating rod 122. The cross seat 22 is located on the side of the crossbar 21 facing the direction of the bamboo pole's material feeding. Each arm of the cross seat 22 is equipped with a cutting blade 221. A horizontal extension rod 222 is located in the middle of the cross seat 22. A conical seat 223 is located at the end of the extension rod 222 facing the direction of the bamboo pole's material feeding, with the small end of the conical seat 223 facing the direction of the bamboo pole's material feeding. One end of the extension rod 222 has a threaded section, on which a rotating sleeve 224 is fitted. The rotating sleeve 224 has a circular array of... A square hole is provided in the base, and a square rod 225 is inserted through the square hole. A chisel 23 is vertically positioned at the outer end of the square rod 225, with the blade of the chisel 23 facing the direction of the bamboo pole's material intake. A limiting plate 226 is provided at the inner end of the square rod 225, and a spring 227 is sleeved on the square rod 225. One end of the spring 227 abuts against the inner wall of the rotating sleeve 224, and the other end abuts against one side of the limiting plate 226. The other side of the limiting plate 226 abuts against the outer wall of the conical seat 223. The length of the square rod 225 extending out of the square hole is controlled by the position of the rotating sleeve 224 on the extension rod 222, thereby meeting the needs of bamboo poles of different sizes.

[0027] Specific usage instructions:

[0028] Start the bamboo pole conveying device to move it towards the direction of the blade group 20, and make each blade group 20 correspond to a bamboo pole. Start the motor 131 to drive the first synchronous wheel 133 to rotate, which in turn drives the second synchronous wheel 135 to drive the cam 121 to rotate eccentrically. This causes the reciprocating rod 122 to move back and forth in the horizontal direction, so that the chisel 23 removes the inner bamboo nodes from the bamboo pole. As the bamboo pole moves forward, the part of the bamboo pole with the inner bamboo nodes removed moves past the rotating sleeve 224, and the splitting blade 221 splits the bamboo pole. This achieves the simultaneous removal of inner bamboo nodes and splitting of the bamboo pole, shortening the process flow and improving work efficiency.

[0029] The above merely describes preferred embodiments of the present application and is not intended to represent the only or the best embodiments. Those skilled in the art should understand that various changes or equivalent replacements made to the present application without departing from the scope of the present application are all within the scope of the present application.
