Technical Field
[0001] This utility model relates to the field of bamboo chopsticks production technology, specifically to an automatic groove-digging device for bamboo chopsticks. Background Technology
[0002] Bamboo chopsticks are long, thin sticks held between the fingers to pick up food or other things. They are mostly used as tableware. They are made of bamboo, wood, ivory, bone, metal, etc., and come in various shapes, such as square or round. During the production of bamboo chopsticks, grooves are cut into their surface using a grooving machine to enhance anti-slip properties and optimize the gripping feel.
[0003] Existing automatic grooving devices for bamboo chopsticks mostly use fixed clamps to hold and fix the bamboo chopsticks during use, which can only be adapted to bamboo chopsticks of a single size. Therefore, there is a need for an automatic grooving device for bamboo chopsticks. Utility Model Content

A guide rod is fixedly connected inside the adjustment groove. An adjustment block is slidably connected to the guide rod. A clamp is fixedly connected to the top of the adjustment block. A fastening bolt is threaded through the outer wall of the clamp. A connecting plate is fixedly connected between the adjustment block and the guide block.
[0006] In use, the distance between the two adjusting blocks can be adjusted by manually sliding the two adjusting blocks on the guide rod inside the adjusting groove, thus adjusting the distance between the two clamps. This allows for the adjustment of bamboo chopsticks of different lengths. The three fastening bolts on the clamps can accommodate bamboo chopsticks of different sizes, ensuring they are clamped and fixed. When the adjusting blocks are adjusted, the guide blocks can slide synchronously on the fixed rod, further improving the stability of the adjusting blocks. The guide blocks can also be locked and fixed by the screw, thus securing the adjusting blocks. Through the cooperation of the above structures, it can accommodate bamboo chopsticks of different lengths. The output shaft of the motor can drive the lead screw to rotate, which converts the rotational motion of the moving block into linear motion, thereby driving the milling cutter to move laterally. Combined with the extension and retraction of the electric cylinder piston rod and the rotational motion of the motor's output shaft, the milling cutter can groove the surface of the bamboo chopsticks.
[0007] Optionally, a horizontal plate is fixedly connected to the outer wall of the vertical plate on one side of the fixed rod. The horizontal plate is located above the fixed rod.

An electric cylinder is fixedly connected to the bottom end of the moving block. A motor is fixedly connected to the end face of the piston rod of the electric cylinder. A milling cutter is provided on the end face of the output shaft of the motor.
[0008] By adopting the above technical solution, the output shaft of the motor can drive the lead screw to rotate, and the lead screw can convert the rotational motion of the moving block into linear motion, thereby driving the milling cutter to move laterally. In conjunction with the extension and retraction of the piston rod of the electric cylinder and the rotational motion of the output shaft of the motor, the milling cutter can be used to carve grooves on the surface of the bamboo chopsticks.
[0009] Optionally, the clamp is provided with a through-type square groove, and three fastening bolts are provided, which are located on both sides and the top of the clamp respectively.
[0010] By adopting the above technical solution, it is beneficial to fix bamboo chopsticks of different sizes and improve the firmness of holding bamboo chopsticks.
[0011] Optionally, connecting rods are fixedly connected to both outer walls of the fastening bolt.
[0012] By adopting the above technical solution, the fastening bolts can be manually rotated more flexibly using the connecting rod.
[0013] Optionally, a support base plate is symmetrically fixedly connected to both sides of the bottom of the processing table, and a placement plate is fixedly connected between the two support base plates, with a storage box placed on the top of the placement plate.
[0014] By adopting the above technical solution, the storage box can collect the wood chips that fall from the adjustment groove.
[0015] Optionally, the fixing rod has multiple threaded holes along its length that are compatible with the screw.
[0016] By adopting the above technical solution, it is beneficial to lock the guide block after the position is adjusted.
[0017] Optionally, two guide rods are provided, and the two guide rods are arranged symmetrically on the left and right.
[0018] By adopting the above technical solution, the stability of the regulating block can be improved.
[0019] Optionally, a rubber pad is attached to the end of the fastening bolt facing the bamboo chopstick.
[0020] By adopting the above technical solution, direct contact between the fastening bolt and the bamboo chopsticks can be avoided, thus preventing wear on the surface of the bamboo chopsticks.
[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: The technical solution of this application allows for the adjustment of the distance between two adjusting blocks by sliding two adjusting blocks on a guide rod inside the adjusting groove. This adjusts the distance between the two clamps, accommodating chopsticks of different lengths. The three fastening bolts on the clamps can accommodate chopsticks of different sizes. Furthermore, when the adjusting blocks are adjusted, the guide blocks can slide synchronously on the fixed rod, further improving the stability of the adjusting blocks. The guide blocks can also be locked and fixed by screws, thus securing the adjusting blocks. Through the cooperation of these structures, the system can accommodate chopsticks of different lengths, improving the flexibility of use. Attached Figure Description
