Description

Technical Field

[0001] The invention relates to the technical field of forest fruit processing, and more specifically to a spiral gap-adjusting walnut peeling machine. Background Art

[0002] As one of the four major dried fruits, walnuts are rich in nutritional value and have an excellent taste, making them popular among people. However, when walnuts are harvested, they are still covered with a layer of green skin about 5 mm thick, commonly known as "green dragon clothing". If the green skin is not removed in time, the walnut shell will be corroded, affecting the appearance of the walnut and the taste of the walnut kernel.

[0003] Although the existing walnut peeling machine can replace the traditional manual peeling work, it not only improves production efficiency, but also protects people's hands from being corroded by "peeling agent", but due to the differences in water, soil, climate and other aspects of China, the size of walnut varieties is quite different. Most of the current walnut peeling machines cannot solve the problem of peeling walnuts of different sizes at the same time; in addition, the peeling is achieved by crushing and washing the peel, which not only causes environmental pollution but also cannot make the peel reused. In order to comply with the development trend of high efficiency, high quality, energy conservation, environmental protection and recycling of walnut peeling technology, it is necessary to solve the size problem, environmental pollution and difficulty in high value-added utilization of the peel in walnut peeling.

DETAILED DESCRIPTION

[0034] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] See also Figure 1 As shown, the present invention provides a spiral gap-adjusting walnut peeling machine, comprising a frame 6; a gap-adjusting feeding mechanism 1, a peeling mechanism 2, a spiral feeding mechanism 3 and a buffering discharging mechanism 4 arranged on the frame 6.

[0037] The gap-adjusting feeding mechanism 1 is used for placing walnuts to be peeled, and can adjust its feeding position.

[0038] The green peeling mechanism 2 is used for cutting and peeling the walnuts to be peeled, so as to separate the fruit from the green peel.

[0039] The spiral feeding mechanism 3 is used for placing the walnuts to be peeled, and for spirally conveying the walnuts to be peeled and the walnuts after peeling.

[0040] The buffer discharging mechanism 4 is used to send the walnuts after the peels are separated out of the peeling machine.

[0041] In the embodiment of the present invention, the green peeling machine realizes the feeding, green peeling, spiral feeding and buffering discharging of walnuts to be peeled through the gap adjustment feeding mechanism 1, the green peeling mechanism 2, the spiral feeding mechanism 3 and the buffering discharging mechanism 4. It can peel the green skin of walnuts of different varieties and sizes. The overall structure is simple, the function is reliable and easy to implement, which improves production efficiency and reduces energy consumption.

[0042] As attached Figure 2As shown, the gap-adjusting feeding mechanism 1 includes a feeding hopper 8 and a guide rail 9, and the guide rail 9 is installed on the frame 6. The guide rail 9 is provided with a feeding hopper 8 for feeding, and the two are slidably matched, that is, the feeding hopper 8 can move axially on the guide rail 9, thereby realizing variable-position feeding of the walnuts to be peeled.

[0043] Furthermore, a folding baffle 7 is provided on the guide rail 9 and on one side of the feeding hopper 8 to prevent the walnuts to be peeled from flying out, thereby ensuring the reliability of walnut feeding.

[0044] In the embodiment of the present invention, the length of the guide rail 9 is 1200mm-1500mm, and two guide rails 9 are installed in parallel on the frame 6, with a spacing of 50mm-70mm. Specifically, preferably, the length of the guide rail 9 is 1200mm and the spacing is 60mm, which can ensure stable installation and reliable operation.

[0045] In the embodiment of the present invention, for walnuts of different sizes, the position of the hopper 8 is changed by moving it on the guide rail 9, which not only achieves the purpose of gap adjustment, but also saves cutting space, saves time and improves work efficiency. By providing the folding baffle 7, not only the defect of walnuts flying out caused by the large distance between the two guide rails 9 is compensated, but also the foldable feature also makes room for the movement of the hopper 8.

[0046] As attached Figure 3 As shown, the peeling mechanism 2 is used for cutting and peeling walnuts, and includes tool fixing plates 11 that are relatively arranged and installed on the frame 6, and a self-positioning spiral milling cutter 10 is arranged between the two tool fixing plates 11 along their circumference. The self-positioning spiral milling cutter 10 is located below the guide rail 9 in the gap adjustment feeding mechanism 1.

[0047] Furthermore, a spring 12 is provided between the self-positioning spiral milling cutter 10 and the tool fixing plate 11, and is used for automatically realizing elastic displacement during the peeling process and under certain pressure conditions, so as to facilitate the cutting and peeling of walnuts, thereby realizing efficient and high-quality peeling of walnuts.

[0048] In the embodiment of the present invention, the self-modifying spiral milling cutter 10 is evenly arranged with 6 to 8 pieces, with a length of 1200 mm to 1500 mm, a width of 40 to 60 mm, a blade tip angle of 30° to 35°, and a helix angle of 25° to 30°. Specifically, preferably, 8 self-modifying spiral milling cutters 10 are arranged, with a length of 1200 mm, a width of 45 mm, a blade tip angle of 32°, and a helix angle of 26°, which can achieve reliable cutting and peeling.

[0049] In the embodiment of the present invention, during the peeling process, the walnuts are peeled by the circumferentially arranged self-variable spiral milling cutter 10 to separate the peels. Under the action of the spring 12, the self-variable spiral milling cutter 10 can automatically realize elastic displacement, which ensures that walnuts of different sizes are always in contact with the spiral blade and cut, realizing efficient peeling, and avoiding damage to the shell due to jamming. In addition, the self-variable spiral milling cutter 10 also has the additional function of screening the fruit and the peel, which also reduces energy consumption compared with the traditional method of peeling the peel with a rotating blade.

[0050] As attached Figure 4 As shown, the spiral feeding mechanism 3 is used to place walnuts and perform spiral conveying, and includes a feeding rubber roller 13, which is located on the inner side of the circumferentially arranged self-positioning spiral milling cutter 10 and corresponds to the position of the feeding hopper 8.

[0051] Discs 15 are installed at both ends of the feeding rubber roller 13, and connecting shafts 16 are installed on the discs 15, and the connecting shafts 16 are installed on the frame 6. The feeding rubber roller 13 is provided with grooves 14 for placing walnuts, and the grooves 14 correspond to the positions of the self-variable spiral milling cutter 10.

[0052] Furthermore, the diameter of the cross section of the feeding rubber roller 13 gradually increases along its axial direction; the grooves 14 are located on the surface of the feeding rubber roller 13 and are arranged in a spiral shape along its circumference, and the rotation direction of the spiral is opposite to that of the self-variable spiral milling cutter 10.

[0053] In the embodiment of the present invention, the walnuts to be peeled are placed in the grooves 14 on the feeding rubber roller 13, and the diameter of the feeding rubber roller 13 gradually increases along its axial direction. The grooves 14 are arranged in a spiral shape, so that when the feeding rubber roller 13 rotates, the walnuts to be peeled and the peeled walnuts can be slowly, uniformly and smoothly pushed axially by the feeding rubber roller 13, and their tangential and radial degrees of freedom are limited, so that the position of the walnuts can be relatively fixed.

[0054] Furthermore, the groove 14 is a semicircular groove, and the radius of the semicircular groove gradually increases from the thick end to the thin end of the feeding rubber roller 13.

[0055] In the embodiment of the present invention, the radius of the groove 14 gradually changes along the axial direction, and the gap between the feeding rubber roller 13 and the self-variable spiral milling cutter 10 changes linearly, so that walnuts of different sizes can be relatively fixed and the demand of milling the green skin of walnuts of different sizes at the same time is met.

[0056] Furthermore, the feeding rubber roller 13 adopts a cylindrical cavity structure, which can reduce its own weight to ensure the reliability of its rotation.

[0057] In the embodiment of the present invention, the length of the feeding rubber roller 13 is 1200mm-1500mm, the diameter of the thin end is φ260mm-φ280mm, and the diameter of the thick end is φ310mm-φ320mm. The semicircular grooves are evenly arranged in 6-8 pieces, with a minimum radius of 20mm-25mm, a maximum radius of 25mm-30mm, and a spiral angle of 45°-60°. Specifically, preferably, the diameter of the thin end of the feeding rubber roller 13 is φ270mm, the diameter of the thick end is φ312mm, the semicircular grooves are evenly arranged in 8 pieces, with a minimum radius of 20mm, a maximum radius of 30mm, and a spiral angle of 45°, so as to realize reliable spiral feeding.

[0058] In the embodiment of the present invention, since the rotation direction of the spiral of the self-variable spiral milling cutter 10 is opposite to the rotation direction of the spiral of the groove 14 on the feeding rubber roller 13, when the feeding rubber roller 13 rotates clockwise, it drives the walnuts to be cut and peeled; when the feeding rubber roller 13 rotates counterclockwise, it drives the walnuts to be scraped and rubbed on the back of the blade, taking off the residual attachments on the surface of the shell, which plays the role of preliminary cleaning of the walnuts. It has a simple structure, reliable function and is easy to implement.

[0059] As attached Figure 5 As shown, the buffer discharge mechanism 4 includes an elastic discharge hopper 17, which is arranged on the frame 6 and corresponds to the position of the thin end of the feeding rubber roller 13. The elastic discharge hopper 17 is used to receive the walnuts peeled by the spiral feeding mechanism 3, and can prevent the walnuts from splashing due to centrifugal movement, providing guidance for their smooth outflow.

[0060] In the embodiment of the present invention, after the walnuts are cut and peeled by the peeling mechanism 2, when they flow out of the spiral feeding mechanism 3, they may fly around due to the tangential acceleration they are subjected to. The elastic discharge hopper 17 can prevent the walnuts from splashing due to centrifugal motion and can be smoothly discharged, with a simple and reliable structure.

[0061] Furthermore, the frame 6 is also provided with a motor 5 (see Figure 1 As shown), the motor 5 is connected to the connecting shaft 16 on the feeding rubber roller 13, and the motor 5 drives the feeding rubber roller 13 to rotate.

[0062] In the embodiment of the present invention, a recovery device may be further provided on the frame 6 and below the spiral feeding mechanism 3 to collect the peels and other attachments of the walnuts to be peeled after cutting and peeling.

[0063] In the embodiment of the present invention, before cutting begins, the feed hopper 8 is moved on the guide rail 9 to change its relative position on the guide rail 9. The walnuts to be peeled are fed through the feed hopper 8 and fall into the groove 14 on the feeding rubber roller 13.

[0064] During the cutting process, the motor 5 drives the feeding rubber roller 13 to rotate, and the walnuts to be peeled are relatively fixed through the groove 14, creating good conditions for the self-variable spiral milling cutter 10 to efficiently and high-quality cut the green skin. The feeding rubber roller 13 drives the walnuts to be peeled to rotate, so that they contact the self-variable spiral milling cutter 10, and the self-variable spiral milling cutter 10 is used to cut and peel the walnuts to be peeled, so as to separate the peels.

[0065] Since the grooves 14 are arranged in a spiral shape, the walnuts can be slowly, evenly and steadily pushed along the axial direction during the rotation of the feeding rubber roller 13, so as to realize the spiral feeding work. After the cutting is completed, the peeled walnuts are fed into the buffer discharge mechanism 4, and the walnuts flow out of the machine under the guidance of the elastic discharge hopper 17, so as to complete the discharge.

[0066] In the above, the feeding position of the walnuts to be peeled can be adjusted by sliding cooperation between the feed hopper 8 and the guide rail 9, that is, the position where the walnuts fall into the groove 14 on the feeding rubber roller 13 can be adjusted. The groove 14 is a semicircular groove with a gradually increasing radius, which is convenient for positioning walnuts of different sizes and also enables the self-variable spiral milling cutter 10 to start cutting from a position where the gap matches the size of the walnut, thereby shortening the cutting time and improving the processing efficiency.

[0067] The spiral gap-adjusting walnut peeling machine provided in the embodiment of the present invention can improve the efficiency and quality of walnut peeling, and the blocky green peels produced during the cutting process can be effectively recovered, thereby avoiding the loss of useful components in the green peels, increasing the added value of walnut products, and reducing environmental pollution.

[0068] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
