Description

Technical Field

[0001] This utility model relates to the field of needle roller piercing fruit technology, specifically a needle roller for an oil grinding machine. Background Technology

[0002] Fruit oil extractors are key equipment in the deep processing of citrus fruits, widely used in the extraction of essential oils from the peels of fruits such as citrus, navel oranges, grapefruits, and lemons. The needle roller, as the core component of the oil extractor, primarily functions to puncture the oil cells in the fruit peel using needle plates on the roller, thereby releasing the essential oils and achieving efficient extraction.

[0003] Currently, common needle-punching rollers typically consist of an all-metal inner shaft tube and an outer stainless steel needle-punching plate. To provide sufficient support, this design uses thickened metal tubing as the inner shaft tube. Although its structure is relatively simple, the overall weight of the roller places higher demands on the frame structure of the oil mill during rotation, increasing the operational burden on the equipment. Furthermore, the poor elasticity of metal materials results in insufficient bounce of fruit on the roller surface, making it difficult to achieve a rapid and uniform oil cell puncture effect. Fruit often moves slowly as it passes over the needle-punching roller due to insufficient bounce, and may even be stuck on the roller surface for extended periods, causing fruit accumulation and blockage. This not only affects the smooth flow of fruit but also significantly reduces the efficiency of oil cell puncture in the peel. Because the oil cells on the peel are not fully punctured, the efficiency of essential oil extraction is low, thus affecting the utilization rate of the fruit in deep processing and further reducing production efficiency. Therefore, there is an urgent need for an improved needle-punching roller device to overcome the above-mentioned technical defects and meet the production needs of deep processing of citrus fruits. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a needle roller for an oil grinding machine, so as to solve the problems of large weight, poor elasticity, uneven oil cell puncture and easy blockage of fruit running in the prior art, thereby improving the overall performance of the equipment and the efficiency of deep processing of fruit.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a needle-punched roller for an oil grinding machine, comprising a shaft tube, a nylon roller, a needle-punching plate, and stainless steel bolts. The shaft tube is a hollow structure located at the innermost layer of the needle-punched roller. The nylon roller wraps around the outer surface of the shaft tube and has high elasticity to enhance the bounce performance of the needle-punched roller. The needle-punching plate wraps around the outer surface of the nylon roller, and the surface of the needle-punching plate is provided with needles. These needles are used to puncture the oil cells on the surface of the fruit. The needles are designed with a conical structure, and openings are provided on the inclined surface of the needles, so that one needle can form several spikes, which can better and more evenly puncture the oil cells on the surface of the fruit. The needle-punching plate, the nylon roller, and the shaft tube are fastened together by stainless steel bolts.

[0006] Furthermore, the needle plate is made of thin stainless steel sheet, and the needles are evenly distributed on the surface of the needle plate through a stamping process.

[0007] Furthermore, the needles can be designed in a semi-circular or triangular shape to accommodate the need to pierce the skin of different fruits.

[0008] Furthermore, the shaft tube is supported by carbon steel to reduce the overall weight and decrease rotational resistance during operation.

[0009] Furthermore, the nylon roller is made of highly elastic nylon material, and its thickness is adapted to the bouncing force required for fruit movement, effectively preventing fruit blockage.

[0010] Furthermore, the needles are arranged in a grid pattern on the outer surface of the needle plate, which ensures that the oil cells of the fruit peel are punctured evenly when the fruit rolls on the roller surface.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The needle-punched roller device of this utility model significantly improves the performance of the needle-punched roller through lightweight design, application of highly elastic materials and optimization of needle structure.

[0013] 2. The combination of hollow shaft tube and nylon roller reduces the overall weight of the device, reduces the operating burden of the equipment, and improves stability; the high elasticity design of the nylon roller improves the smoothness of fruit handling and avoids clogging problems.

[0014] 3. The multi-sharp needle structure and evenly distributed design improve the efficiency of piercing the oil cells of the fruit peel and the extraction rate of essential oil; the densely packed fine needles on the roller can effectively collect fruit oil by continuously piercing the oil cells of the fruit peel without damaging the pulp, so that the material can be further processed.

[0018] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "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 this utility model 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 this utility model.

[0019] Please see Figure 1-2 This utility model provides a technical solution: a needle-punched roller for an oil grinding machine, comprising: a shaft tube 1, a nylon roller 2, a needle-punching plate 3, and stainless steel bolts 4. The shaft tube 1 is a hollow structure and is located in the innermost layer of the needle-punched roller. The nylon roller 2 is wrapped around the outer surface of the shaft tube 1 and has high elasticity to enhance the bounce performance of the needle-punched roller. The needle-punching plate 3 is wrapped around the outer surface of the nylon roller 2, and needles 5 are provided on the surface of the needle-punching plate 3. The needles 5 are used to puncture the oil cells on the surface of the fruit. The needles 5 are designed with a conical structure and openings 6 are provided on their inclined surfaces, so that one needle 5 forms multiple spikes to more evenly puncture the oil cells on the surface of the fruit. The needle-punching plate 3, the nylon roller 2, and the shaft tube 1 are fastened together by stainless steel bolts 4.

[0020] This specific embodiment improves the overall lightweight level and bounce performance by designing a hollow shaft tube 1 and a high-elasticity nylon roller 2; the multi-head structure of the needles 5, evenly distributed on the surface of the needle plate 3, ensures the efficiency and effectiveness of piercing the fruit oil cells; the design of the opening 6 further increases the number of needles 5, improving the uniformity of piercing the fruit peel, thereby releasing more fruit peel essential oils; the overall design ensures the smooth rolling process of the fruit on the needle roller, avoiding the problem of accumulation and blockage.

[0021] The combination of hollow shaft tube 1 and high-elasticity nylon roller 2 significantly reduces the overall weight of the needle roller, reduces the operating burden of the equipment, and improves stability; the high-elasticity material of nylon roller 2 enables the fruit to have better bouncing performance during rolling, avoids clogging, and improves piercing efficiency; the conical structure and multi-spiked head design of needle 5 not only improves the uniformity of oil cell piercing, but also improves the efficiency of essential oil extraction.

[0022] The needle-punching plate 3 is made of thin stainless steel sheet, and the needles 5 are evenly distributed on the surface of the needle-punching plate 3 through a stamping process. The needle-punching plate 3 achieves the effect of reducing weight while ensuring strength and durability. The needles 5 are manufactured by precision stamping process and are evenly distributed on the surface of the needle-punching plate 3 to provide stable and efficient piercing ability. The stamping process ensures the dense arrangement of the needles 5, thereby improving the piercing efficiency of fruit oil cells, while maintaining the overall structural reliability of the needle-punching roller.

[0023] The material of the needle plate 3 can be replaced with other corrosion-resistant materials, such as titanium alloy or aluminum alloy, to adapt to different usage environment requirements; the distribution pattern of the needles 5 can be adjusted according to the size and shape of the fruit, for example, a higher density arrangement can be used to handle smaller fruits.

[0024] The needle 5 can also be designed as a semi-circle or a triangle to meet the piercing needs of different fruit skins;

[0025] This specific embodiment changes the shape of the piercing needle 5, such as designing it as a semi-circle or a triangle, to adapt to the characteristics of different types of fruit peels; the semi-circular piercing needle is suitable for softer fruit peels, reducing resistance during the piercing process; the triangular piercing needle can provide stronger piercing ability and is suitable for harder fruit peels.

[0026] The different shapes of the needles in the needle 5 can better adapt to the skin characteristics of various fruits and improve the piercing effect; the semi-circular needles reduce damage to the fruit skin and are suitable for handling more delicate fruits; the triangular needles provide higher piercing strength and are suitable for thick and hard fruit skins.

[0027] The shaft tube 1 is supported by carbon steel. Using carbon steel as the material for the shaft tube 1 utilizes its high strength and lightweight characteristics to reduce the overall weight while ensuring the support force of the roller body. The lightweight design reduces the inertia of the needle roller during operation, thereby reducing the rotational resistance during equipment operation and improving operating efficiency.

[0028] The material of the shaft tube 1 can be replaced with aluminum alloy or composite material to further reduce weight and improve corrosion resistance; a reinforcing rib design can be added to the inner wall of the shaft tube 1 to enhance structural strength while maintaining lightweight characteristics.

[0029] The nylon roller 2 is made of high-elasticity nylon material; the high-elasticity nylon material enables the nylon roller 2 to provide appropriate rebound force when the fruit rolls, reducing the adhesion and stagnation between the fruit and the roller surface; the thickness of the nylon roller 2 is optimized to meet the bounce force requirements of different fruits, ensuring that the fruit can pass through the needle roller smoothly and avoid clogging;

[0030] Nylon material can be replaced with other highly elastic polymers, such as polyurethane or rubber, to meet specific needs; the surface of nylon roller 2 can be enhanced with an anti-slip texture design to further improve the stability of the fruit during rolling.

[0031] The needles 5 are arranged in a grid pattern on the outer surface of the needle-punching plate 3. The needles 5 adopt a grid pattern arrangement to form evenly distributed puncture points, ensuring that the oil cells on the skin of the fruit can be fully covered and punctured during the rolling process. The grid pattern design optimizes the arrangement density of the needles and improves the overall processing effect of the needle-punching roller on the fruit.

[0032] The grid-like arrangement of the needles 5 ensures that the fruit skin is pierced evenly and completely, avoiding any omissions; it also improves the uniformity of the fruit's rolling on the needle roller and reduces clogging problems caused by uneven needle distribution.

[0033] The foregoing has shown and described the basic principles, main features and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this utility model as claimed.
