Description

Technical Field

[0001] This utility model relates to a torreya nuts opening device, and more particularly to a high-speed laser opening device for torreya nuts. Background Technology

[0002] Chinese torreya (scientific name: *Torreya grandis* 'Merrillii' Hu), also known as round torreya, fine torreya, horn torreya, pearl torreya, etc., is a superior cultivated type of the *Torreya* tree in the Taxaceae family. It is a rare and precious dried fruit tree species unique to China. In recent years, the scale of Chinese torreya cultivation in my country has expanded rapidly, mainly growing in the more humid southern regions, such as Zhejiang, Fujian, Jiangxi, Anhui, and Hunan. Besides being eaten as a snack and for its seed oil, Chinese torreya also has medicinal uses. It has many applications in traditional Chinese medicine. Its rich nutritional components include high-quality protein, healthy fats, carbohydrates, dietary fiber, vitamins, and minerals, including antioxidants, cardiovascular health benefits, digestive aid, energy provision, bone strengthening, blood sugar regulation, and immune system enhancement. Chinese torreya has a low glycemic index, making it suitable for diabetics and helping to stabilize blood sugar levels.

[0003] The shells of Torreya nuts are opened to facilitate subsequent roasting and flavor absorption, and to make peeling easier for consumers. Currently, Torreya nuts are opened primarily by manual, laser, and mechanical methods. The opening process mainly involves manual methods, the use of extrusion-type opening tools, and laser-cutting devices. Manual opening using small handheld opening tools is labor-intensive, limiting production efficiency. Furthermore, manual operation is affected by the skill level and physical condition of the operators, leading to inconsistent work quality. Mechanical opening equipment requires careful adjustment of the distance between the screw conveyor and the opening tool to ensure optimal opening results. Due to the size variations of torreya nuts, without adjustment, the high-speed rotating cutting blade can easily come into contact with the kernel, leading to processing losses. Laser opening machines primarily utilize a focused, high-power, high-density laser beam to irradiate the surface of the torreya nut shell. The laser beam instantly ablates and melts the shell at the irradiation point to achieve the desired cut. Existing laser equipment has a production capacity of only 60-70 catties / hour, which is low and cannot meet the production needs of enterprises. Utility model patent application number 202320894680.0 discloses a nut laser opening machine, but it suffers from low opening efficiency, difficulty in effectively handling smoke and impurities generated during the opening process due to the burning of the shell, and a fixed laser power that is difficult to adapt to different sized materials.

[0004] Patent application number 202311326271.1 describes a torreya tree opening machine and method. However, the mechanical opening process makes it difficult to accurately adjust the cutting force of the cutter, which can easily cause over-cutting and damage to the fruit. In addition, it has problems such as low opening efficiency.

[0005] Patent application number 202421053336.X dual-channel Torreya grandis laser opening machine: during the process of material conveying by vibratory plate, if the material falls from the feed pipe to the conveyor line at too fast a speed, it is easy to cause material collapse and blockage, thus limiting the opening output of Torreya grandis.

[0037] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described in detail with reference to the embodiments.

[0038] Example 1

[0039] A high-speed laser-opening device for Torreya nuts includes a feeding device 1, a conveying device 2, a mounting frame 3, and a laser 4. The conveying device 2 is mounted on the mounting frame 3. The feeding device 1 conveys Torreya nuts to the conveying device 2. The laser 4 is located above the conveying device 2 and performs opening processing on the Torreya nuts thereon. In this embodiment, the laser 4 is equipped with two laser nozzles 41.

[0040] The laser-opening equipment also includes a clamping and conveying device 5 for holding the Torreya grandis nut. The clamping and conveying device 5 holds the Torreya grandis nut, making it more stable on the conveying device 2 and facilitating the laser 4 to open the nut. The clamping and conveying device 5 includes a first clamping unit 51 and a second clamping unit 52 that can move left and right. The first clamping unit 51 and the second clamping unit 52 move left and right to adjust Torreya grandis nut of different sizes, ensuring that the nut is centered on the conveying device 2, guaranteeing that the laser 4 opens the nut from the middle. Both the first clamping unit 51 and the second clamping unit 52 are mounted on the mounting frame 3 via buffer members 53, which allow the first clamping unit 51 and the second clamping unit 52 to return to their original positions promptly after movement. The conveying device 2 is located between the first clamping unit 51 and the second clamping unit 52, with the first clamping unit 51 and the second clamping unit 52 positioned on both sides of the conveying device 2, facilitating the clamping of the Torreya grandis nut on the conveying device 2.

[0041] The first clamping unit 51 and the second clamping unit 52 can move left and right. In conjunction with the buffer 53, the buffer 53 can provide flexible space for the left and right movement of the clamping units and can promptly drive the clamps to reset after movement. The spacing can be adaptively adjusted according to the actual size of the torreya nuts. When the torreya nut enters between the first clamping unit 51 and the second clamping unit 52, the first clamping unit 51 and the second clamping unit 52 are squeezed and move to both sides, and the buffer 53 deforms accordingly. After the torreya nut passes through or completes clamping and positioning, the first clamping unit 51 and the second clamping unit 52 of the buffer 53 quickly reset to receive the next torreya nut.

[0042] The clamping and conveying device 5 can not only stably clamp the torreya nuts of different specifications, preventing them from shifting or rolling during conveying and opening, but also ensure the smoothness of continuous processing by timely resetting, ensuring that each torreya nut is accurately positioned in the center below the laser nozzle, fundamentally solving the problem of opening deviation, improving opening accuracy and consistency, and thus improving product qualification rate and production efficiency.

[0043] Both the first clamping unit 51 and the second clamping unit 52 include a clamping box 511, a clamping motor, a driving wheel 512, a driven wheel 513, and a clamping belt 514. The clamping motor is installed in the clamping box 511 and connected to the driving wheel 512. The clamping motor is used to drive the driving wheel 512 to rotate. One end of the clamping belt 514 is wrapped around the driving wheel 512, and the other end is wrapped around the driven wheel 513. The driving wheel 512 drives the driven wheel 513 to rotate through the clamping belt 514. A clamping channel 54 is formed between the two clamping belts 514, and the torreya nuts are clamped on the clamping channel 54.

[0044] The mounting frame 3 has multiple mounting slots 31. In this embodiment, there are four mounting slots 31, and each mounting slot 31 contains a clamping unit. Both ends of the clamping box 511 are mounted in the mounting slots 31 via pins 55. Buffers 53 are fitted onto the pins 55 on both sides of the clamping box 511. The buffers 53 fitted onto the pins 55 on both sides of the clamping box 511 can precisely drive the clamping box 511 to reset using its own elastic potential energy after the clamping box 511 moves due to clamping the torreya nuts. The synchronous reset design on both sides ensures that the spacing between the clamping units is consistent, avoiding inaccurate clamping and positioning due to unilateral reset deviation. This stable reset function ensures that each torreya nut is accurately clamped at the preset position of the laser opening during continuous processing, maintaining the continuity and precision of high-speed processing.

[0045] The conveying device 2 includes a conveying motor 21, a first conveyor belt 22, a second conveyor belt 23, a drive roller 24, and a driven roller 25. The conveying motor 21 is connected to the drive roller 24 and drives it to rotate. The first conveyor belt 22 and the second conveyor belt 23 are both mounted on the drive roller 24 and the driven roller 25. The drive roller 24 drives the driven roller 25 to rotate through the two conveyor belts. There is a gap 26 between the first conveyor belt 22 and the second conveyor belt 23. The laser hole on the laser 4 is directly facing the gap 26. Due to the setting of the gap 26, the torreya nuts will not easily roll on the two conveyor belts. At the same time, the gap 26 is also to facilitate laser penetration and avoid damage to the conveyor belts.

[0046] The feeding device 1 includes a storage hopper 11, a vibrating plate 12, a vibrating plate support 13, and a conveying pipe 14. The vibrating plate 12 is based on the principle of electromagnetic vibration. It mainly uses the frequency and amplitude of the driving power supply to make the spiral track of the vibrating plate 12 generate high-frequency micro-amplitude vibration. Through the combined action of centrifugal force and inertial friction generated by the vibrating plate 12, the torreya nuts in the storage hopper 11 are conveyed along the track in a spiral manner. The storage hopper 11 and the vibrating plate 12 are both installed on the vibrating plate support 13. The vibrating plate 12 is located directly below the storage hopper 11. The outlet end of the vibrating plate 12 is connected to the inlet end of the conveying pipe 14. The conveying pipe 14 conveys the torreya nuts on the vibrating plate 12 to the conveying device 2. The storage hopper 11 ensures a continuous supply of torreya nuts, preventing processing continuity from being affected by raw material shortages. The vibratory feeder 12 uses vibration to initially sort and arrange the torreya nuts, ensuring they enter the conveying pipe 14 in an orderly manner and preventing accumulation and congestion. The conveying pipe 14 then precisely guides the torreya nuts output from the vibratory feeder 12 to the conveying device 2, ensuring they enter the space between the first clamping unit 51 and the second clamping unit 52 in a stable posture. This structured feeding process lays the foundation for the precise clamping of the subsequent clamping and conveying device 5 and the accurate positioning of the laser 4, reducing positional deviations caused by chaotic feeding. Working in synergy with the clamping and conveying device 5, it further improves the overall processing stability and accuracy.

[0047] The laser opening device also includes an air pump 6 and a water chiller 7. The air pump 6 is connected to the laser nozzle 41 of the laser 4 via an air pipe. Similarly, during the laser opening process of the torreya nuts, a large amount of smoke is generated. This smoke enters the laser nozzle 41 and can clog the focusing lens. Therefore, the air pump 6 is connected to the laser nozzle 41 to blow away impurities and smoke during the laser opening operation, preventing impurities and smoke from entering the laser nozzle 41. Smoke is generated during the opening process, which is then smoked away by a smoke extractor. The water chiller 7 is connected to the laser nozzle 41 of the laser 4 via a water pipe to cool it down. During the laser opening process, the laser tube and laser device generate a large amount of heat, which requires the water chiller to cool the components.

[0048] Example 2

[0049] Example 2 is basically the same as Example 1, except that the feeding device 1 also includes a damper 15, a guide rod 16, and a damping support 17. The damper 15 is installed on the damping support 17, and the guide rod 16 is located on the damper 15. One end of the guide rod 16 is connected to the outlet of the conveying pipe 14, and the other end extends to the conveying device 2. After the Torreya grandis material is conveyed to the outlet at high speed by the vibrating plate 12, the Torreya grandis seeds will bounce severely during the high-speed vibration conveying. The damper 15 is set up to play a connecting role. After the Torreya grandis seeds fall through the conveying pipe 14, the guide rod 16 receives the material and, through the vibration of the damper 15, converts the impact kinetic energy of the Torreya grandis seeds falling at high speed into a flexible forward posture and arranges the material neatly. The neatly arranged Torreya grandis enter the adaptive clamping conveying device 5 to achieve material centering. To avoid frequency impact caused by the different vibration amplitudes of the vibratory feeder 12 and the damper 15, the vibratory feeder support 13 of the vibratory feeder 12 and the damping support 17 of the damper 15 are designed separately. To avoid material blockage during high-speed transmission, the guide rod 16 is installed at a height lower than the discharge port of the vibratory feeder 12, and a conveying pipe 14 is installed between the two to facilitate process connection.

[0050] A fixing plate 18 is fixed to the lower end of the guide rod 16. The fixing plate 18 is fixed to the damper 15 by fasteners. The guide rod 16 is provided with a guide groove 161. Notches 162 are provided on both sides of the guide groove 161. The notches 162 face the fasteners and provide operating space to facilitate the passage of screws, thereby facilitating the fastening of the fixing plate 18 to the damper 15. The cross-sectional shape of the guide groove 161 is V-shaped. The end of the guide rod 16 extending to the conveying device 2 is the tip 163. The depth of the guide groove 161 at the tip 163 gradually decreases. Through the vibration of the V-shaped guide groove 161, the impact kinetic energy of the high-speed falling Torreya seeds is converted into a flexible forward posture and the material is neatly arranged, achieving rapid deceleration and providing working conditions for the subsequent adaptive clamping and conveying device 5 to position itself.

[0051] Example 3

[0052] Example 3 is essentially the same as Example 1 or 2, except that the laser opening device also includes a material elevator 8, which is connected to and supplies material to the storage hopper 11. The addition of the material elevator 8 further optimizes the continuity and automation of the feeding process. In traditional feeding methods, the storage hopper 11 requires frequent manual feeding, which not only increases labor costs but may also cause equipment shutdown due to untimely feeding, affecting production efficiency. The material elevator 8, however, enables automatic conveying and replenishment of Torreya grandis raw materials, continuously supplying material to the storage hopper 11, avoiding the lag of manual intervention, and ensuring that the storage hopper 11 always maintains sufficient raw material reserves. This provides a stable material source for subsequent feeding components such as the vibratory feeder 12 and conveying pipe 14. Working in conjunction with the storage hopper 11, vibratory feeder 12, and other structures, it forms a complete automated process from raw material lifting to precise feeding, reducing production interruptions caused by manual feeding, further improving the overall processing efficiency and stability of the equipment, and providing continuous assurance for the precise operation of the clamping device and laser.
