Description

Technical Field

[0001] This utility model relates to a chestnut cutting device, and more particularly to a chestnut laser cutting feeding device. Background Technology

[0002] To facilitate chestnut cutting (opening), existing chestnut opening equipment uses blades to cut openings in the chestnut shells. This process is cumbersome, and the high-speed rotating blades often damage the chestnut kernels, resulting in significant losses. To address this issue, laser cutting has emerged, such as the chestnut laser cutting device disclosed in CN215468942U. This device has a discharge port located directly above a V-shaped conveyor plate on a storage bin. Chestnuts in the storage bin are discharged through the discharge port and fall onto the V-shaped conveyor plate. The V-shaped conveyor plate is used to arrange and vibrate the chestnuts. A vibrating device, including a vibrating motor and a vibrating disc, is connected to the V-shaped conveyor plate. The vibrating disc is fixed to the side wall of the V-shaped conveyor plate, and the vibrating motor drives the vibrating disc to vibrate. Thus, the chestnuts are arranged and conveyed on the V-shaped conveyor plate by vibration and the chestnuts' own gravity. However, for use in stores where chestnuts are cut and roasted on-site, the vibrator generates significant noise, and the vibration also affects the surrounding environment. Utility Model Content

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] like Figures 1 to 7As shown, a chestnut cutting and feeding device includes a feeding frame 61, a feeding hopper 7, a drive unit 67, a conveyor chain 63, and a feeding seat 64. The feeding frame 61 has a feeding trough 611 at its top. The feeding hopper 7 is mounted 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 communicating with the feeding trough 611. The drive unit 67 is mounted on the feeding frame 61 and connected to the conveyor chain 63, which is movably located within the feeding trough 611. The feeding seat 64 is mounted 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 positioned opposite the feeding hole 71 and below it.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] like Figure 5 As shown, 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.

[0030] The drive motor 674 can be connected to the drive sprocket 671 through a synchronous belt transmission mechanism to drive the drive sprocket 671.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] The technical principles of this utility model have been described above with reference to specific embodiments. 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.
