Abstract
Description
Technical Field
[0001] This utility model provides a cutter, belonging to the field of bamboo chopsticks processing technology, and particularly relates to a fixed-length cutter for bamboo chopsticks processing. Background Technology
[0002] Bamboo chopsticks, also known as bamboo-made chopsticks, are tableware made from bamboo through a series of processing techniques. They are characterized by their natural, environmentally friendly, and durable nature. The processing includes material selection, cutting, sorting, steaming, drying, milling, polishing, and packaging. Through these steps, the bamboo is transformed into bamboo chopsticks that meet usage requirements.
[0003] The existing cutting process plays a crucial role in bamboo chopstick processing. It divides the bamboo raw material into sections of specific lengths and specifications, preparing them for subsequent processing steps such as polishing and sharpening, ensuring that the chopsticks meet usage requirements. Current cutting structures typically rely on cutting blades for direct cutting. Manual cutting makes it difficult to guarantee uniform lengths, while CNC cutting is costly and requires cutting section by section, resulting in low efficiency. The existing cutting process often necessitates multiple adjustments to the position of the bamboo raw material or manual intervention to ensure accuracy. This not only increases labor intensity but also significantly reduces production efficiency, failing to meet the demands of large-scale, high-efficiency bamboo chopstick processing.

By optimizing the structure, it achieves precise fixed-length cutting and improves production efficiency.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a bamboo chopstick processing fixed length cutter, including a base, a plurality of evenly distributed placement seats are provided above the base, bamboo chopstick raw materials are evenly distributed on the side of the placement seats away from the base, a drive shaft is provided inside the placement seats and a plurality of evenly distributed cutting blades are fixedly connected to the drive shaft and placed between the placement seats.
[0006] Preferably, the base is provided with a rotating groove corresponding to the cutting blade, the cutting blades are staggered around the drive shaft, the cutting blades do not overlap in the length direction of the drive shaft, and the cutting blades do not contact the bamboo chopstick material at the same time.
[0007] Preferably, the storage base has a groove corresponding to the bamboo chopstick material to ensure that the bamboo chopstick material will not be misaligned or roll when it is cut, and connecting seats are fixedly connected to both sides of the storage base.
[0008] Preferably, the interior of the connecting seat is connected by a tension spring to a cover placed above the connecting seat. The cover corresponds to the groove on the shelf and engages with the bamboo chopsticks.

The bearing structures are located between the placement seat and the base, and the bottom and the base are fixedly connected by bolts. A drive motor that is mechanically connected to the drive shaft is provided on one end of the base.
[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0011] This device uses evenly distributed supports above a base to hold raw bamboo chopsticks. A drive shaft running through the supports houses evenly distributed cutting blades positioned between the supports. When the drive shaft rotates, the cutting blades precisely and evenly cut the raw bamboo chopsticks, ensuring each chopstick is the same length and meeting the requirements for fixed-length cutting. This mechanized cutting method eliminates the need for manual measurement and adjustment of each segment, reducing human intervention and labor intensity while improving cutting efficiency and precision.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] like Figure 1 and Figure 2 As shown, a bamboo chopstick cutting tool for fixed length processing includes a base 1. Several evenly distributed supports 2 are provided above the base 1. Bamboo chopstick raw materials 3 are evenly distributed on the side of each support 2 facing away from the base 1. A drive shaft 4 passes through the support 2, and several evenly distributed cutting blades 5 are fixedly connected to the drive shaft 4 and positioned between the supports 2. The base 1 has rotating grooves 6 corresponding to the cutting blades 5. The cutting blades 5 are staggered around the drive shaft 4, do not overlap along the length of the drive shaft 4, and do not contact the bamboo chopstick raw materials 3 simultaneously. The supports 2 have grooves 7 corresponding to the bamboo chopstick raw materials 3 to ensure that the bamboo chopstick raw materials 3 do not roll or shift during cutting. Connecting seats 8 are fixedly connected to both sides of the supports 2. A cover 10, positioned above the connecting seat 8, is connected inside the connecting seat 8 via a tension spring 9. The cover 10 corresponds to the groove 7 on the support 2 and engages with the bamboo chopstick raw materials 3. The two ends of the drive shaft 4 are fitted with bearing structures 11 corresponding to itself. The bearing structures 11 are located between the storage seat 2 and the base 1, and the bottom and the base 1 are fixedly connected by bolts. A drive motor 12 that is mechanically connected to the drive shaft 4 is provided on one end of the base 1.
[0023] In this embodiment, the entire device is supported by a base 1, and a storage seat 2 evenly distributes and loads bamboo chopsticks 3. A drive shaft 4 passes through the storage seat 2 and drives the cutting blades 5 to rotate and cut. The cutting blades 5 are staggered and do not overlap, avoiding excessive instantaneous load and reducing motor power requirements. The grooves 7 on the storage seat 2 and the spring-loaded structure of the cover 10 ensure the stability of the bamboo chopsticks 3 and prevent misalignment and rolling during cutting. The drive motor 12 drives the drive shaft 4 to rotate via a mechanical connection, achieving efficient cutting. This structural combination enables precise fixed-length cutting, improves production efficiency, reduces labor intensity, and meets the needs of large-scale bamboo chopstick processing.
[0024] like Figure 3 and Figure 4 As shown, the base 2 has grooves 7 corresponding to the bamboo chopsticks material 3 to ensure that the bamboo chopsticks material 3 will not roll or shift during cutting. Connecting seats 8 are fixedly connected to both sides of the base 2. A cover 10 is connected to the inside of the connecting seat 8 via a tension spring 9. The cover 10 corresponds to the grooves 7 on the base 2 and engages with the bamboo chopsticks material 3. Bearing structures 11 corresponding to itself are sleeved on both ends of the drive shaft 4. The bearing structures 11 are located between the base 2 and the base 1, and the bottom of the bearing structure is fixedly connected to the base 1 by bolts. A drive motor 12, which is mechanically connected to the drive shaft 4, is located on one end of the base 1.
[0025] In this embodiment, the groove 7 on the holder 2 and the cover 10, through the elastic action of the tension spring 9, firmly engage the bamboo chopstick material 3, preventing displacement during cutting and ensuring cutting accuracy. This spring-loaded clamping structure is simple, reliable, and easy to adjust, adaptable to bamboo chopstick materials of different diameters. The cooperation between the drive shaft 4 and the bearing structure 11 ensures stable rotation of the drive shaft 4, reducing vibration and noise during operation and improving cutting smoothness. The drive motor 12 drives the drive shaft 4 to rotate through a mechanical connection, providing sufficient power to ensure that the cutting blade 5 can efficiently complete the cutting task. The entire device has a reasonable structural design, with tight connections between components and clear positional relationships. Together, they achieve efficient and precise fixed-length cutting of bamboo chopsticks, significantly improving production efficiency and product quality.
[0026] at the same time,
[0027] Staggered cutting blade layout: By distributing the cutting blades 5 in a staggered manner around the drive shaft 4, and ensuring that the cutting blades do not overlap along the length of the drive shaft, time-sharing cutting is achieved. This design avoids the problem of excessive instantaneous load caused by multiple blades cutting simultaneously in traditional cutting machines, and reduces the motor power requirement.
[0028] Multi-station synchronous processing: The storage seats 2 are evenly distributed and can simultaneously load multiple bamboo chopsticks 3. Combined with the spring-pressing structure of the cover 10, batch processing is achieved, improving efficiency.
[0029] Asynchronous contact design: The staggered distribution of the cutting blades ensures that there is a time interval between each blade contacting the bamboo. For example, if the drive shaft speed n = 1200 rpm and the number of cutting blades z = 6, then Δt = 8.3 ms, which significantly reduces vibration noise and reduces the cutting pressure on the drive shaft.
[0030] V-shaped groove + spring cover: The storage seat 7 is made of 6063-T5 aluminum alloy with a V-shaped groove (angle 90°±2°), which is matched with the polyurethane rubber pressure block (Shore hardness 70A) of the cover 10. The friction coefficient μ=0.4-0.6 can resist the cutting impact force Fc≤200N (the shear strength of bamboo τ=8-12MPa).
[0031] The steps for using this device are as follows: First, place the bamboo chopstick material 3 in the groove 7 of the base 2. Secure the bamboo chopstick material 3 with the tension spring 9 on the connecting seat 8 and the cover 10 to ensure that it will not roll or shift during the cutting process. Next, start the drive motor 12 on one end of the base 1. The drive motor 12 drives the drive shaft 4 to rotate through a mechanical connection. The cutting blades 5 on the drive shaft 4 are staggered around the drive shaft 4 and do not overlap in the length direction of the drive shaft 4, achieving time-sharing cutting, avoiding excessive instantaneous load, and reducing the power requirement of the motor. During the cutting process, the staggered distribution of the cutting blades 5 ensures that there is a time interval between each blade contacting the bamboo, significantly reducing vibration noise and reducing the cutting pressure on the drive shaft 4. Finally, the base 2 is evenly distributed and can simultaneously load multiple bamboo chopstick materials 3. Combined with the spring clamping structure of the cover 10, batch processing is achieved, improving efficiency. The entire device is supported by the base 1. The cooperation between the drive shaft 4 and the bearing structure 11 ensures the stable rotation of the drive shaft 4, reduces vibration and noise during operation, improves the smoothness of cutting, and realizes efficient and precise fixed-length cutting of bamboo chopsticks, which significantly improves production efficiency and product quality.
