[0027] The present invention will now be further described with reference to the accompanying drawings.

[0028] like Figures 1 to 10 As shown, a chestnut laser cutting device includes a laser 2, a housing 1, a feeding device 6, a receiving frame 8, a sensor 9, and a controller 5. The laser 2 is mounted on the housing 1, and the laser head 21 is located on the top of one side of the housing 1. The feeding device 6 is located on one side of the housing 1 and below the laser head 21. The sensor 9 is mounted on the top of the feeding device 6 and is used to detect the chestnuts fed out by the feeding device 6 in order to control the operation of the laser 2. The controller 5 is mounted on the housing 1 and is connected to the laser 2, the feeding device 6, and the sensor 9. It is used to control the feeding device 6 to feed out the chestnuts and to control the laser 2 to cut the chestnuts according to the detection signal detected by the sensor 9.

[0029] When sensor 9 detects the chestnut, it sends a signal to controller 5. After receiving the signal, controller 5 activates laser 2, and laser head 21 emits a laser. The laser cuts the chestnut shell at high temperature, creating an opening in the chestnut shell.

[0030] The presence of openings in chestnuts makes them prone to moisture loss during roasting, and chestnuts with openings are also more likely to dry out after prolonged storage, affecting their texture. Therefore, it is best to cut chestnuts after they are roasted. However, roasted chestnuts are softer, and existing chestnut-opening machines, which use blades, cannot cut chestnuts with soft shells. Laser cutting, on the other hand, is not affected by the hardness of the chestnut shell and can quickly create openings. Therefore, chestnuts can be cut after roasting, preserving the moisture in the chestnut kernels, improving their texture, and preventing them from drying out.

[0031] The laser 2 mainly includes a laser head 21 and a main unit 22. The main unit 22 is installed inside the housing 1, and the laser head 21 is inserted into the adjustment hole of the housing 1.

[0032] Both the housing 1 and the feeding device 6 can be installed on the base plate 4. The base plate 4 facilitates the installation of the feeding device 6 and the housing 1. The bottom of the base plate 4 is equipped with rubber feet.

[0033] To facilitate height adjustment of the laser head 21, a height adjustment device 3 is also included. The height adjustment device 3 is mounted on the base plate 4 and located inside the housing 1. It is connected to the main unit 22 of the laser 2 and used to adjust the height of the laser 2. Specifically, the height adjustment device 3 includes a linear module 31 and an adjustment base 33. The linear module 31 is vertically mounted on the base plate 4, and its slide 32 is connected to the adjustment base 33. The adjustment base 33 is mounted on one side of the main unit 22. The linear module 31 drives the main unit 22 to rise and fall, thereby achieving height adjustment of the laser head 21. The linear module 31 can be manual or electric; the electric type is connected to the controller 5.

[0034] Controller 5 is a touch screen controller, which is easy to use.

[0035] To enhance safety and prevent foreign objects or human hands from entering the working range of the laser head 21 and causing accidents, a protective cover is also included. The protective cover can be mounted on the laser head 21 or on the housing 1. For easy adjustment of the laser head 21's height, the protective cover is mounted on the housing 1. The protective cover is also located above the feeding device 6, ensuring the laser head 21 is in a closed state during operation and guaranteeing safety. The protective cover includes a fixed cover 23 and an adjustable cover 24. The fixed cover 23 is mounted on the housing 1 and located on the adjustment hole. The top of the adjustable cover 24 has several oblong holes, which are connected to the fixed cover 23 by screws, facilitating easy adjustment of the height of the adjustable cover 24 so that it fits snugly against the feeding device 6.

[0036] like Figures 6 to 10 As shown, the feeding device 6 includes a feeding frame 61, a feeding hopper 7, a drive unit 67, a conveyor chain 63, and a feeding seat 64. The top of the feeding frame 61 has a feeding trough 611. The feeding hopper 7 is installed on the top of the feeding frame 61 and located at one end of the feeding trough 611. The bottom of the feeding hopper 7 has a feeding hole 71, which communicates with the feeding trough 611. The drive unit 67 is installed on the feeding frame 61 and connected to the conveyor chain 63. The conveyor chain 63 is movably located within the feeding trough 611. The feeding seat 64 is installed on the conveyor chain 63 and arranged in an array. The feeding seat 64 has a discharge trough 641 for placing chestnuts. The conveyor chain 63 is also arranged opposite to the feeding hole 71 and located below it.

[0037] Chestnuts to be processed are placed in the feeding hopper 7. The chestnuts enter the feeding seat 64 above the feeding hole 71. Driven by the conveyor chain 63, the feeding seat 64 moves from one end of the feeding trough 611 to the other. This movement causes the chestnuts to enter the discharge trough 641, with one chestnut placed in each trough. The diameter of the discharge trough 641 is smaller than the diameter of the chestnut. The array of feeding seats 64 allows for the sequential feeding of chestnuts. This process eliminates the need for a vibrator, resulting in low noise and vibration, while also simplifying and compacting the structure.

[0038] The laser is located above the conveyor chain 63. When the chestnut moves below the laser, the laser emits a laser beam, which cuts the chestnut shell. To ensure consistent cutting depth and avoid cutting into the chestnut kernel or insufficient cutting depth, a horizontal support plate 62 is installed below the conveyor chain 63 opposite to the laser. The horizontal support plate 62 is fixed to the feeding frame 61 and slides below the conveyor sprocket, so that the conveyor chain 63 is horizontal in the area opposite the laser and its height remains constant, preventing significant fluctuations in the height difference between the chestnut and the laser due to sag caused by gravity.

[0039] The other end of the feeding rack 61 is equipped with a receiving frame 8, which is used to place chestnut packaging boxes. The cut chestnuts fall directly into the chestnut packaging boxes.

[0040] To ensure smoother and more reliable sequential feeding of chestnuts, a feeding ramp 612 is provided at one end of the top of the feeding frame 61. The feeding hopper 7 is located on the feeding ramp 612, and one end of the conveyor chain 63 is positioned opposite the feeding ramp 612. When the inclined conveyor chain 63 drives the feeding seat 64 to move upward, it can keep the chestnuts that have not entered the discharge trough 641 in the feeding hopper 7 under the action of gravity, thus preventing the chestnuts that have not entered the discharge trough 641 from entering the laser cutting area along with the conveyor chain 63 and the feeding seat 64, and enabling the chestnuts to be fed out sequentially.

[0041] The bottom of the feeding hopper 7 is triangular, and the feeding hole 71 is located on one side, which allows the chestnuts to be concentrated into the feeding hole 71 and then fed out. The triangular bottom of the feeding hopper 7 also facilitates matching with the feeding ramp 612.

[0042] To prevent chestnuts from falling through the gap between the inclined conveyor chain 63 and the hopper 7, a feeding baffle 72 is provided at the bottom of the feeding hole 71. The feeding baffle 72 is located above the conveyor chain 63 and close to the conveyor chain 63 to reduce the gap between them.

[0043] The drive unit 67 includes a drive motor 674, a drive sprocket 671, an auxiliary sprocket 672, and a driven sprocket 673. The drive motor 674 is mounted on the feeding frame 61 and connected to the drive sprocket 671. The drive sprocket 671 is rotatably mounted on one end of the feeding frame 61 via bearings and is located below the feeding hopper 7. The auxiliary sprocket 672 and the driven sprocket 673 are both rotatably mounted on the feeding frame 61 via bearings. The driven sprocket 673 is located at the other end of the feeding frame 61, and the auxiliary sprocket 672 is located between the drive sprocket 671 and the driven sprocket 673, and is located at one end of the feeding ramp 612. A horizontal support plate 62 is located between the auxiliary sprocket 672 and the driven sprocket 673. A conveyor chain 63 is sleeved on the drive sprocket 671, the auxiliary sprocket 672, and the driven sprocket 673.

[0044] The drive motor 674 can be connected to the drive sprocket 671 through a synchronous belt transmission mechanism to drive the drive sprocket 671.

[0045] To further ensure the sequential delivery of chestnuts and prevent them from escaping from the discharge trough 641 during delivery, a feeding rod 65 is provided on the feeding seat 64. The feeding rod 65 is located on both sides of the discharge trough 641 and is used to block the chestnuts.

[0046] Two conveyor chains 63 are arranged side by side. The two conveyor chains 63 can increase the contact area with the feeding seat 64, making the feeding seat 64 more stable when it moves.

[0047] The feeder seat 64 has a U-shaped structure and connection holes 642 on both sides. The connection holes 642 are inserted into the connecting shaft 631 of the conveyor chain 63 and are located on both sides of the conveyor chain 63 to prevent axial movement along the connecting shaft 631.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
