Description

Technical Field

[0001] This invention relates to the field of bamboo chopsticks processing, and in particular to a dimensional cutting machine for bamboo chopsticks processing. Background Technology

[0002] Chopsticks are defined as long, thin sticks held between the fingers to pick up food or other things. They are mostly used as tableware and are made of materials such as bamboo, wood, ivory, bone, and metal. Their shapes vary, including square and round. They can be considered a national treasure of China and stand out among tableware from all over the world. They are praised by Westerners as a symbol of Eastern civilization. The history of chopsticks in my country can be traced back to the Shang Dynasty, from about 1600 BC to 1046 BC. In the process of processing bamboo chopsticks, a bamboo chopstick sizing machine is needed to cut the bamboo chopsticks to a fixed size.

[0003] Patent application number CN201921620628.6 discloses a cutting device for bamboo chopstick production, including a base box, a vertical plate installed on one side of the upper part of the base box, a support plate installed on the other side, a second drive mechanism installed on the upper part of the base box to control the vertical plate of the support plate to move closer to support the bamboo chopstick raw material on the side of the vertical plate, a top plate installed on the upper part of the vertical plate, a cutting component slidably installed on one side of the vertical plate, and a first drive mechanism installed at the bottom of the top plate to control the cutting component to move up and down along the vertical plate; the upper part of the base box has a first collection trough for collecting finished bamboo chopsticks and a second collection trough for collecting cutting waste. The raw bamboo chopsticks are placed on the upper part of the bottom box to fix them. The first driving mechanism drives the cutting component and the pressing component to move downward synchronously to cut the fixed raw bamboo chopsticks. The cut bamboo chopsticks fall into the first collection trough for temporary storage, while the short pieces formed after cutting are pressed into the second collection trough by the pressing component for temporary storage. Patent application number: CN202122915021.4 also discloses a bamboo chopsticks sizing device for bamboo chopsticks production, including a receiving component and a cutting component. The housing assembly includes a base plate, side plates, baffles, a feed cylinder, and a chopstick holder. The side plates are vertically and fixedly connected to the base plate, and the baffles are fixedly installed on both sides of the side plates. Both the feed cylinder and the chopstick holder are located on the sides of the side plates, with the feed cylinder positioned directly above the chopstick holder. The feed cylinder is designed as a trumpet shape, wider at the top and narrower at the bottom. In use, a round strip is placed into the feed cylinder. Because the feed cylinder and chopstick holder are vertical, the strip falls naturally and aligns. Simultaneously, due to the trumpet shape of the feed cylinder, excess strip cannot enter. After the strip aligns inside the chopstick holder, the bearing seat slides closer to the holder, and the motor drives the grinding wheel to rotate, cutting the strip. However, this type of sizing machine can only cut shorter bamboo chopstick strips once, and cannot meet the need for multiple cuts of longer bamboo strips.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dimensional cutting machine for processing bamboo chopsticks.

[0006] This invention can be achieved through the following technical solutions: This invention discloses a dimensional cutting machine for bamboo chopsticks, comprising a frame, on which a cutting screw and a cutting slide are mounted. The cutting screw is driven to rotate by a conveyor motor. A slide connected to the cutting screw by a thread is mounted on the cutting screw. A fixing block is also mounted on one side of the slide, and a cutting motor is fixed on the fixing block. A cutting wheel is fixed to the output end of the cutting motor. Multiple cutting hydraulic push rods are fixed on the slide, and the ends of the cutting hydraulic push rods are all fixed to the fixing block. The frame also includes a receiving screw and a receiving slide, and the receiving screw is driven to rotate by a receiving motor. The take-up screw is equipped with a slide plate that is threadedly connected to the take-up screw. The take-up slide rod passes through the slide plate and is slidably connected to the slide plate. A fixing plate is also provided above the slide plate. Support devices are evenly arranged above the fixing plate. The support devices include two support plates fixed on the fixing plate. Multiple lifting hydraulic push rods are also fixed on the frame above the fixing plate. A limit plate is also provided above the fixing plate. The lifting hydraulic push rods are evenly fixed to the limit plate. Limit devices are fixed at positions corresponding to the support devices on the limit plate. The limit devices include limit blocks symmetrically arranged on both sides of the support device.

[0007] Preferably, the support plate has a U-shaped structure.

[0008] Preferably, the limiting block has an arc-shaped structure.

[0009] Preferably, multiple hydraulic push rods for receiving material are fixed on the slide plate, and the ends of the hydraulic push rods are all fixed to a fixed plate. An arc-shaped receiving plate is also fixed on the frame, and clearance grooves are provided on the receiving plate at positions corresponding to the support device. When the sized bamboo strip moves above the receiving plate, the hydraulic push rods for receiving material shorten after receiving an electrical signal, the support device descends, and the bamboo strip remains on the receiving plate. Then, the receiving motor drives the receiving screw to rotate in the opposite direction. After the support plate reaches below the limit block, the hydraulic push rods for receiving material extend, the support plate returns to its initial position, and the long bamboo strip is placed on the support plate again. This process is repeated to cut the long bamboo strip to size again. This device can collect the bamboo strips after the previous sized cut while cutting the long bamboo strip to size, greatly improving the production efficiency of bamboo chopsticks.

[0010] Preferably, guide plates are fixed on both sides of the frame of the fixed plate. Bamboo strips that cannot meet the size requirements at both ends are cut off and fall onto the guide plates, where they slide down and are collected.

[0011] Compared with existing technologies, the present invention has the following advantages: This device can perform multiple dimensional cuts on long bamboo strips, producing a large number of dimensional bamboo strips after cutting, which greatly improves the production efficiency of bamboo chopsticks.

A fixing block 6 is also mounted on one side of the slide table 5, on which a cutting motor 8 is fixed. A cutting wheel 9 is fixed at the output end of the cutting motor 8. Multiple cutting hydraulic push rods 7 are fixed on the slide table 5, and the ends of the cutting hydraulic push rods 7 are all fixed to the fixing block 6. The frame 1 also includes a receiving screw 10 and a receiving slide bar 11. The receiving screw 10 is driven to rotate by a receiving motor 13. A receiving screw 10 is mounted on the receiving screw 10. A slide plate 12 is threadedly connected to the receiving screw 10. The receiving slide rod 11 passes through the slide plate 12 and is slidably connected to the slide plate 12. A fixing plate 15 is also provided above the slide plate 12. Support devices 17 are evenly arranged above the fixing plate 15. The support device 17 includes two support plates 16 fixed on the fixing plate 15. Multiple lifting hydraulic push rods 18 are also fixed on the frame 1 above the fixing plate 15. A limit plate 19 is also provided above the fixing plate 15. The lifting hydraulic push rods 18 are evenly fixed to the limit plate 19. Limiting devices are fixed on the limit plate 19 at positions corresponding to the support device 17. The limiting device includes limiting blocks 20 symmetrically arranged on both sides of the support device 17. Multiple long bamboo strips of undetermined size are stacked on support plate 16. The lifting hydraulic push rod 18 is an electro-hydraulic push rod structure. After receiving an electrical signal from the control box, the motor of the lifting hydraulic push rod 18 extends, and the limit block 20 descends, fixing the bamboo strips to the support plate 16. The cutting motor 8 drives the cutting wheel 9 to rotate. After receiving an electrical signal from the control box, the cutting hydraulic push rod 7 extends, and the cutting wheel 9 extends between the two support plates 16 of the support device 17. After contacting each bamboo strip, the cutting wheel 9 cuts the bamboo strip. After the bamboo strip is cut, the cutting hydraulic push rod 7 shortens, and the cutting wheel 9 returns to its initial position. The conveying motor 4 drives the cutting screw 2 to rotate. Because the cutting screw 2... The slide table 5 is threadedly connected to the cutting screw 2. When the cutting screw 2 rotates, the slide table 5 moves in the direction of the cutting screw 2. The cutting wheel 9 reaches the position of the next support device 17 and cuts the bamboo strip again through the cutting wheel 9. The operation is repeated, and the bamboo strip is cut multiple times through the cutting wheel 9. After the bamboo strip is cut multiple times, the lifting hydraulic push rod 18 receives an electrical signal and shortens. The limit block 20 rises. After the limit block 20 reaches above the support plate 16, the receiving motor 13 drives the receiving screw 10 to rotate. The slide plate 12 moves to one side of the frame 1. After the bamboo strip is sized, it is removed after moving to one side of the frame 1. This device can realize multiple sized cuts of long bamboo strips and produce a large number of sized bamboo strips after cutting, which greatly improves the production efficiency of bamboo chopsticks.

[0015] Among them, the support plate 16 has a U-shaped structure.

[0016] Among them, the limiting block 20 has an arc-shaped structure.

[0017] The device includes multiple hydraulic push rods 14 fixed on the slide plate 12, with the ends of each rod fixed to a fixed plate 15. An arc-shaped receiving plate 21 is also fixed to the frame 1, with clearance grooves 22 on the receiving plate 21 corresponding to the support device 17. When the sized bamboo strip moves above the receiving plate 21, the hydraulic push rods 14 shorten upon receiving an electrical signal, the support device 17 descends, and the bamboo strip remains on the receiving plate 21. The receiving motor 13 then drives the receiving screw 10 to rotate in the opposite direction. When the support plate 16 reaches below the limit block 20, the hydraulic push rods 14 extend, and the support plate 16 returns to its initial position. The long bamboo strip is then placed back on the support plate 16, and the cycle repeats, allowing for another sized cut. This device can collect the bamboo strips from the previous sized cut while simultaneously performing sized cuts, greatly improving the production efficiency of bamboo chopsticks. Example
