Description

Technical Field

[0001] The invention relates to the field of chopstick processing, in particular to a wood fiber chopstick branching device. Background Art

[0002] Traditional chopsticks made of raw wood need to be processed into long strips of wood with a length of several meters first, and then cut into short square strips slightly longer than the finished chopsticks, and then sharpened with an abrasive belt, usually grinding half of it into a cone, and then cutting the thin end flat and making the thick end into a four-sided pyramid head, and finally polishing the chopsticks to remove the edges and corners.

[0003] There will be a lot of scraps in the processing of raw wood chopsticks, which consumes a lot of wood and affects the ecological balance. The texture of raw wood is soft and easy to bend and deform. The raw wood needs to be steamed and dried first, and the processing steps are cumbersome. Moreover, raw wood is prone to mold in daily use.

[0004] Processing existing wood fiber boards into chopsticks not only effectively avoids the problem of mold on chopsticks, but also the wood fiber boards are harder in texture and do not need to be steamed, thus reducing the processing steps. Wood fiber boards are made by grinding wood into wood fibers, adding edible glue and mixing them fully, and finally pressing them into boards, which greatly reduces the waste of wood, consumes less wood, and saves tree resources.

[0005] Usually, the wood fiber boards on the market are processed according to traditional processing technology, and the short square strips are sharpened after processing. However, due to the high hardness of the wood fiber boards, the sanding belt used for sharpening will be greatly worn out, and the sanding belt needs to be replaced frequently, which increases the processing cost. Summary of the invention

[0006] Now, based on the existing wooden chopstick processing technology, in order to avoid the problem of large loss of abrasive belts when using abrasive belts to process materials with greater hardness, a processing technology for wood fiber chopsticks is proposed.

[0007] Step 1: The wood fiber board is cut along a set track to branch out the masterbatch of wood fiber chopsticks.

[0008] Step 2: Cut the four sides of the mother material and process the formed wooden chopstick blank. The processed wooden chopstick blank has a trapezoidal projection of the four sides, the end face of the thick end is a relatively large square, and the end face of the thin end is a relatively small square.

[0009] Step 3: Process both ends of the wooden chopstick blank and polish and remove the edges and corners.

[0010] If the four trapezoidal faces of the wooden chopstick blank are divided into four faces A, B, C, and D in clockwise order, faces B and D are the cutting faces in step 1, and the forward projections of these two faces are rectangles, and the forward projections of faces A and C are trapezoids. Then, faces A and C are cut in step 2, and the forward projections of the four faces of the processed wooden chopstick blank are all trapezoids.

[0011] The processing technology of the wood fiber chopsticks replaces the traditional sanding belt sharpening with a knife saw cutting method, which fundamentally avoids the loss of the sanding belt.

[0012] The purpose of the present invention is to construct a wood fiber chopstick branching device based on the demand for cutting and branching the mother material of the wood fiber chopsticks in step 1 on the basis of a proposed processing technology of wood fiber chopsticks.

The second motor 143 is started to drive the second motor synchronous pulley 152 to rotate. The rotation of the second motor synchronous pulley 152 drives the second synchronous belt 151 to rotate. The rotation of the second synchronous belt 151 drives the second screw rod synchronous pulley 150 to rotate. The rotation of the second screw rod synchronous pulley 150 drives the second screw rod 149 to rotate. The rotation of the second screw rod 149 will drive The second movable bottom plate 146 connected thereto moves backwards, and when the second movable bottom plate 146 moves backwards, the second cylinder 141 also moves backwards accordingly, and when the second cylinder 141 moves backwards, the L-shaped push plate 145 moves backwards, and the push-out boss 136 moves along with the movement of the L-shaped push plate 145, and the push-out boss 136 moves to a position where no plate is placed above, and the second cylinder 141 pushes out the push rod, which drives the L-shaped push plate 145 to move upwards, and the push-out boss 136 rises along with the rise of the L-shaped push plate 145, so that the push-out boss 136 and the plate to be pushed out are at the same height; (3) The second motor 143 rotates in the opposite direction to move the push-out boss 136 forward. The push-out boss 136 moves forward to push the lowest wood fiber board forward. The wood fiber board located in the rear half of the mounting table 102 will be pushed to the front half of the mounting table 102. The pushed-out board is pressed by the spring pressure plate 108 to limit the vertical position of the board. After the cutting work starts, the action of pushing out the wood fiber board is intermittent. The interval time is the sum of the time to complete one cutting and the time to adjust the angle and move to the cutting position. (4) The first cylinder 112 is extended and retracted to move the U-shaped mounting block 113 connected thereto forward or backward. The movement of the U-shaped mounting block 113 drives the stopper 111 to move. The movement of the stopper 111 drives the first slide box 110 to rotate. The rotation of the first slide box 110 drives the sawing device 128 to rotate to a set angle. The sawing device 128 located on the right side of the plate starts to start. (5) The rotation of the first motor 127 drives the first motor synchronous pulley 126 to rotate, the rotation of the first motor synchronous pulley 126 drives the first synchronous belt 124 to rotate, the rotation of the first synchronous belt 124 drives the first screw synchronous pulley 125 to rotate, the rotation of the first screw synchronous pulley 125 drives the first screw 154 to rotate, the rotation of the first screw 154 drives the first movable base 131 connected thereto to move leftward, the first movable base 131 moves leftward and drives the sawing device 128 connected thereto to move leftward for cutting, when the next cutting work is required, the sawing device 128 needs to be moved to the right side of the plate again to cut from right to left.
