Description

Technical Field

[0001] This invention discloses a fully automated production line for bamboo products, belonging to the field of automated production. Background Technology

[0002] Replacing wood with bamboo is a relatively new term that has emerged in recent years. In the context of global warming and the need to protect our planet, the world has called for a ban on indiscriminate logging and the search for new alternatives to wood. Bamboo has been promoted worldwide in this context. Bamboo is a fast-growing material that can mature in just 5 years, which is far superior to the decades-long growth cycle of wood. Furthermore, the proper harvesting of bamboo is beneficial for the cultivation of bamboo forests.

[0003] The current process for producing thin bamboo strips with rounded ends, such as bamboo popsicle sticks, tongue depressors, or coffee sticks, is as follows: First, the outer surface of the bamboo strip is polished to make it smooth. Then, it is cut according to the length of the product. The cut raw material is collected and placed on a stamping machine to form an arc-shaped end structure. This stamping method makes the bamboo strip form a structure with rounded ends. Alternatively, the tool grinding method used in Chinese patent application number "CN201820734826.4" is adopted. In both cases, the bamboo strip raw material that has been cut to the correct length needs to be clamped and fixed before grinding, and finally the material is released.

[0004] Existing methods all require cutting the raw materials to their length, clamping and fixing them, and finally forming the arc structure at both ends. Because each cut raw material needs to be clamped and fixed, frequent loading and unloading are required, resulting in complicated processes and reduced efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automated production line for bamboo products, which solves the problem of needing to clamp and fix each sheared raw material, resulting in frequent loading and unloading, causing cumbersome processes and reduced efficiency.

[0006] The present invention achieves the above-mentioned objective through the following technical solution: a fully automated bamboo product production line, comprising a feeding mechanism, a polishing and drawing mechanism for polishing and grinding the surface of bamboo strips, and a rotary shearing mechanism for controlling the length and forming the arc end of the bamboo strips in sequence through the production process. A material feeding and conveying mechanism for feeding bamboo strips into the polishing and drawing mechanism is connected between the feeding mechanism and the polishing and drawing mechanism. The rotary shearing mechanism includes a first body and two rotary shearing components rotatably mounted on the first body. Two rotary shearing components are symmetrically arranged, and a gap for the bamboo strips to pass through is provided between the two rotary shearing components. Several protrusions are fixedly arranged on the rotary shearing components, and two arc-shaped blades for cutting bamboo strips are symmetrically arranged on the protrusions.

[0007] By adopting the above technical solution, and utilizing the cooperation between the feeding mechanism, polishing and drawing mechanism, and rotary shearing mechanism, fully automated processing is achieved when processing thin bamboo strips with rounded ends, such as popsicle sticks, tongue depressors, or coffee sticks. This improves work efficiency. Furthermore, when processing bamboo strips, rotary cutting replaces the existing stamping or cutting methods. Rotary cutting eliminates the need for clamping and fixing, and combines the existing step of length cutting of bamboo strips with the forming of the rounded ends to achieve a one-step forming effect. Users can select different specifications of rotary shearing parts according to the type of product they need to produce. The length of the bamboo strip passing through each time the rotary shearing part rotates and cuts is equal to the required length of the product.

[0008] Preferably, the first machine body is also rotatably equipped with two first transmission wheels for transmitting and stabilizing bamboo strips.

[0009] By adopting the above technical solution, when the bamboo strip is fed into the rotary shearing mechanism after the outer surface of the bamboo strip has been treated by the polishing and drawing mechanism, the first transmission wheel achieves a stable transmission effect.

[0010] Preferably, an anti-slip transmission belt is also provided between the first transmission wheel and the rotating shearing member to prevent the bamboo strip from shifting position, and the anti-slip transmission belt is also provided with an opening for the protrusion to pass through.

[0011] By adopting the above technical solution, when cutting to the last section of the bamboo strip, the anti-slip transmission belts abut against each other, preventing the end of the bamboo strip from curling up and causing the cutting position to shift when the rotating shearing device is cutting, thus improving the product yield.

[0012] Preferably, the upper feeding mechanism includes a stacker for timely replenishment of bamboo strips and a sorting machine for evenly discharging the stacked bamboo strips. The sorting machine includes a guide hopper, a stirring component rotatably mounted on the guide hopper, and a vibrator fixedly mounted on the guide hopper. The material distribution and conveying mechanism is located below the guide hopper.

[0013] By adopting the above technical solution, the bamboo strips on the stacker are sorted and separated by the cooperation between the guide hopper agitator and the vibrator, so that the bamboo strips are arranged one by one when they fall onto the material distribution and conveying mechanism.

[0014] Preferably, the material feeding and conveying mechanism includes a first conveyor belt, a plurality of spacers fixedly mounted on the first conveyor belt, and a propulsion assembly for pushing bamboo strips into the polishing and drawing mechanism. The plurality of spacers are spaced apart. A brush for preventing bamboo strips from accumulating is fixedly mounted on the outer wall of the guide hopper. The propulsion assembly includes a cylinder and a sensor for controlling the operation of the cylinder. The sensor is connected to the cylinder.

[0015] By adopting the above technical solution, the partition plate on the first conveyor belt forms a separate space to accommodate bamboo strips, which prepares for feeding into the polishing and drawing mechanism later, avoiding the accumulation of bamboo strips and causing malfunctions. At the same time, the brush is used to sweep the excess bamboo strips into the separate space formed by the next partition plate when two or more bamboo strips are piled up, ensuring that there is only one bamboo strip in each separate space. Furthermore, the accuracy of feeding into the polishing and drawing mechanism is ensured through the cooperation between the sensor and the cylinder.

[0016] Preferably, the polishing and wire drawing mechanism includes a second body, a second transmission wheel rotatably mounted on the second body, and a cutting wheel for grinding and polishing. Several of the second transmission wheel and the cutting wheel are provided. The cutting wheel is configured with an I-shaped structure and is distributed on both sides of the bamboo strip being processed.

[0017] By adopting the above technical solution, the outer surface of bamboo strips can be polished using a blade wheel.

[0018] Preferably, a finished product collection mechanism is provided on the side of the rotary shearing mechanism away from the polishing and wire drawing mechanism. The finished product collection mechanism includes a second conveyor belt and a trough for waste collection located below the second conveyor belt. The second conveyor belt has through holes for waste to pass through.

[0019] By adopting the above technical solution, bamboo strips and scraps from rotary cutting can be separated, making it easier for staff to collect and use them later.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] By utilizing the coordination between the upper feeding mechanism, polishing and drawing mechanism and rotary shearing mechanism, fully automated processing is achieved when processing thin bamboo strips with round ends, such as popsicle sticks, tongue depressors or coffee sticks, thus improving work efficiency.

[0022] By replacing existing stamping or cutting methods with rotary cutting, work efficiency is increased, frequent loading and unloading are no longer required, and the processing actions are made more continuous.

[0023] At the same time, the existing steps of first cutting the bamboo strips to length and forming the arc structure at both ends are combined to achieve the effect of one-step forming. The length is cut at the same time as the arc end of the bamboo strip, simplifying the process steps.

[0024] By cooperating with the anti-slip transmission belt, the first transmission wheel and the rotating shearing component, the bamboo strips are prevented from deviating during the shaping and shearing process, thus ensuring the shearing effect.

[0025] By incorporating a brush to prevent bamboo strips from piling up, a simple structure is achieved that makes the product easy to use.

[0026] Through the cooperation between the sensor and the cylinder, it is ensured that the cylinder can stably push the bamboo strip into the polishing and drawing mechanism;

[0027] The polishing and drawing mechanism and the rotary shearing mechanism produce bamboo waste that can be used as raw materials for feed, edible fungi, pet bedding, pellets, bamboo boards, organic fertilizer, mosquito coils, etc., thus generating economic benefits. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In this description, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1-6As shown, a fully automated bamboo product production line includes a feeding mechanism, a polishing and drawing mechanism for polishing and grinding the surface of bamboo strips, and a rotary shearing mechanism for controlling the length and forming the curved ends of the bamboo strips. A feeding and conveying mechanism for feeding bamboo strips into the polishing and drawing mechanism is connected between the feeding mechanism and the polishing and drawing mechanism, achieving fully automated production and improving work efficiency. The rotary shearing mechanism includes a first body 1 and two rotary shearing components 2 rotatably mounted on the first body 1. Two rotary shearing components 2 are symmetrically arranged, and a passage for the bamboo strips to pass through is provided between the two rotary shearing components 2. The gap is filled by the rotating shearing component 2, which cuts simultaneously from above and below to ensure that the cutting position of the bamboo strip does not move, thus guaranteeing the length of the bamboo strip and the arc-shaped structure at the end after cutting. Several protrusions 3 are fixedly installed on the rotating shearing component 2, and two arc-shaped blades 4 are symmetrically arranged on each protrusion 3 for cutting the bamboo strip. The arc-shaped blades 4 ensure the formation of the arc-shaped end. Simultaneously, an anti-slip transmission belt 6 is fitted between the first transmission wheel 5 and the rotating shearing component 2 to prevent the bamboo strip from shifting position, further improving the stability of the bamboo strip during cutting. The anti-slip transmission belt 6 also has openings for the protrusions 3 to pass through, thus avoiding affecting normal use. Furthermore, when cutting the last section of the bamboo strip, the anti-slip transmission belts 6 abut against each other, preventing the end of the bamboo strip from curling up and causing the cutting position to shift during cutting by the rotating shearing component 2, thereby improving the product yield.

[0037] Meanwhile, a finished product collection mechanism is provided on the side of the rotary shearing mechanism away from the polishing and wire drawing mechanism. The finished product collection mechanism includes a second conveyor belt 20 and a trough 21 for waste collection located below the second conveyor belt 20. The second conveyor belt 20 has through holes 22 for waste to pass through, so that the sheared products and the formed waste can be separated and collected, further improving the convenience of work.

[0038] The upper feeding mechanism includes a stacker 7 for timely replenishment of bamboo strips and a sorting machine for evenly discharging the stacked bamboo strips. During production, workers can more intuitively understand the material addition by observing the number of bamboo strips on the stacker 7. The sorting machine includes a guide hopper 9, a stirring component 10 rotating on the guide hopper 9, and a vibrator 11 fixed on the guide hopper 9. The material distribution and conveying mechanism is located below the guide hopper 9. By utilizing the cooperation between the stirring component 10 and the vibrator 11 in the guide hopper 9, the bamboo strips on the stacker 7 are sorted and separated, ensuring that each bamboo strip falls onto the material distribution and conveying mechanism. The material distribution and conveying mechanism includes a first conveyor belt 12, several partition plates 13 fixed on the first conveyor belt 12, and a propulsion component that pushes the bamboo strips into the polishing and drawing mechanism. The several partition plates 13 are spaced apart, so that each pair of partition plates 13 forms an independent space for accommodating the bamboo strips, ensuring that the bamboo strips are stably fed into the polishing and drawing mechanism. Meanwhile, a brush 14 is fixedly installed on the outer wall of the guide hopper 9 to prevent bamboo strips from piling up. When two or more bamboo strips are piled up, the brush 14 can sweep the excess bamboo strips into the separate space formed by the next partition plate 13, ensuring that there is only one bamboo strip in each separate space. At the same time, the propulsion component includes a cylinder 15 and a sensor 16 for controlling the operation of the cylinder 15. The sensor 16 is connected to the cylinder 15. The sensor 16 senses the passage of the bamboo strip and then works with the cylinder 15 to push the bamboo strip from the first conveyor belt 12 into the polishing and drawing mechanism.

[0039] The polishing and drawing mechanism includes a second body 17, a second transmission wheel 18 rotatably mounted on the second body 17, and a cutting wheel 19 for polishing. Several second transmission wheels 18 and cutting wheels 19 are provided. The second transmission wheel 18 drives the bamboo strip to move forward, and the cutting wheel 19 polishes the outer surface to achieve a smooth finish. The cutting wheels 19 are distributed on both sides of the bamboo strip being processed, so that both the upper and lower surfaces of the bamboo strip can be polished. At the same time, the cutting wheel 19 is set with an I-shaped structure, so that the side wall of the bamboo strip can be polished.

[0040] Working principle: The bamboo strips are fed into the guide hopper 9 by the stacker 7. The bamboo strips are separated by the mixing component 10 and the vibrator 11. The bamboo strips are then discharged sequentially by the first conveyor belt 12. The bamboo strips are cleaned by the brush 14 to prevent accumulation. As the first conveyor belt 12 continues to transport the bamboo strips, the sensor 16 senses the passage of the bamboo strips and then the cylinder 15 pushes the bamboo strips from the first conveyor belt 12 into the polishing and drawing mechanism. The bamboo strips then come into contact with the second drive wheel 18, which drives the bamboo strips forward. At the same time, the cutter wheel 19 polishes the bamboo strips to achieve a smooth outer surface. The bamboo strips are then fed between two anti-slip drive belts 6, which drive the bamboo strips forward. Finally, the rotating shearing component 2 rotates and cuts the bamboo strips.
