Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit processing technology, and in particular to an apple peeling machine that can remove the core. Background Technology
[0002] Apples are a beloved and widely used ingredient in food processing and home kitchens. Whether making apple pie, applesauce, or eating them directly, peeling and corering are common steps.
[0003] Traditional apple core removal methods often rely on manual operation, such as using knives or simple corer tools. This manual method has many inconveniences. On the one hand, manual core removal requires certain skills and experience, and improper operation may lead to a significant loss of apple flesh, affecting the apple's edible value or the yield of subsequent processing. For large-scale apple processing, such as in food processing plants, manual core removal is inefficient and consumes a lot of manpower and time. On the other hand, removing the apple core after traditional core removal is also quite troublesome. It usually requires manually prying or pouring the apple core out of the corer tool. This process not only easily gets your hands dirty but may also cause further damage to the apple flesh. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an apple peeling machine that can remove the core.
[0005] This utility model is achieved using the following technical solution: A core-removing apple peeler includes a base box. A peeling device body is fixedly mounted on the upper surface of the base box. A positioning frame is fixedly connected to the upper surface of the base box. A lower pressure plate is slidably connected inside the positioning frame. A screw is threadedly connected inside the lower pressure plate. A knob is fixedly connected to the top of the screw. A drive motor is fixedly connected to the inner wall of the base box. A lead screw is fixedly connected to the output end of the drive motor. A movable sleeve is threadedly connected to the surface of the lead screw. A knob is fixedly connected to the upper surface of the movable sleeve. The device has a cored hollow tube with limit rods running through both sides of the movable sleeve. An ejector ring is slidably connected inside the cored hollow tube, and a piston rod is fixedly connected to the bottom end of the ejector ring. The main body of the peeling device is a Starfrit electric apple peeler, which uses an electric motor to drive the peeling mechanism. After the apple is placed in the working area of the peeler, the motor drives the peeling blade to move along the circumference of the apple. The blade contacts the surface of the apple and peels off the outer skin. The speed of the motor or the cutting depth of the blade can be adjusted to adapt to different varieties and skin hardness of apples.
[0006] The above technical solution can not only quickly remove the cores from apples, but also automatically push out the cores, reducing the tedious manual core removal process and improving the efficiency of apple processing.
[0007] As a further improvement to the above solution, the bottom end of the screw is rotatably connected to the inner bottom wall of the limiting slide groove.
[0008] The above technical solution improves the accuracy and stability of apple fixing, which helps to facilitate the smooth progress of subsequent core removal operations.
[0009] As a further improvement to the above solution, the top end of the lead screw is rotatably connected to the inner wall of the base box.
[0010] The above technical solution improves the accuracy of the up-and-down movement of the core-removing hollow tube, which helps to accurately perform the core removal operation.
[0011] As a further improvement to the above solution, both ends of the limiting rod are fixedly connected to the inner wall of the base box.
[0012] The above technical solution ensures the vertical up-and-down movement of the core-removed hollow tube, improving the accuracy of the core removal operation.
[0013] As a further improvement to the above solution, a sealing cover is hinged to the surface of the base box.
[0014] As a further improvement to the above solution, the surfaces of both the base box and the peeling device body are provided with holes and grooves that are compatible with the hollow tube for removing the core.
[0015] As a further improvement to the above solution, a limiting groove is formed on the surface of the positioning frame, and the lower pressure plate is slidably connected to the inside of the limiting groove.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention uses a drive motor to rotate a lead screw, causing a movable sleeve to move up and down along the lead screw under the restriction of a limit rod. This movement drives the core removal tube to rise and fall, thus removing the apple core without the need for manual core removal with a knife. Compared to traditional manual core removal, this avoids the instability and skill differences caused by human operation, resulting in fruit pulp loss and improving core removal accuracy. After core removal, the drive motor is reversed, causing the core removal tube to descend. When the piston rod contacts the bottom wall of the base box, the core removal tube is pressed, pushing the internal sliding ejection ring upward, automatically ejecting the apple core. This eliminates the need for manual core removal or emptying, avoiding the potential for soiling hands and further damaging the apple pulp when manually cleaning apple cores in traditional methods, greatly facilitating the cleaning of apple cores.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0025] Example:
[0026] Please combine Figure 1-4This embodiment of an apple peeler for removing cores includes a base box 1. A peeling device body 2 is fixedly mounted on the upper surface of the base box 1. A positioning frame 3 is fixedly connected to the upper surface of the base box 1. A lower pressure plate 5 is slidably connected inside the positioning frame 3. A screw 6 is threadedly connected inside the lower pressure plate 5. A knob 7 is fixedly connected to the top of the screw 6. A drive motor 8 is fixedly connected to the inner wall of the base box 1. A lead screw 9 is fixedly connected to the output end of the drive motor 8. A movable sleeve 10 is threadedly connected to the surface of the lead screw 9. A core-removing hollow tube 11 is fixedly connected to the upper surface of the movable sleeve 10. Limiting rods 12 pass through both sides of the movable sleeve 10. A pusher is slidably connected inside the core-removing hollow tube 11. The bottom end of the ejector ring 13 is fixedly connected to a piston rod 14. First, the apple is placed on the surface of the peeling device body 2, and the peeling device body 2 peels the apple. After peeling, the knob 7 is turned, which drives the screw 6 to rotate. Since the screw 6 is threadedly connected to the lower pressure plate 5, the rotation of the screw 6 causes the lower pressure plate 5 to descend along the positioning frame 3, thereby pressing the apple. Here, the bottom end of the screw 6 is rotatably connected to the inner bottom wall of the limiting slide groove 4. The lower pressure plate 5 slides in the limiting slide groove 4 to ensure that the lower pressure plate 5 can move up and down stably, effectively pressing the apple and ensuring the stability of the apple during the core removal process. The drive motor 8 is started, and the drive motor 8 drives the screw... When rod 9 rotates, the top of lead screw 9 is rotatably connected to the inner wall of base box 1. The movable sleeve 10, threaded to the surface of lead screw 9, moves with the rotation of lead screw 9. Limiting rods 12 pass through both sides of movable sleeve 10, and both ends of the limiting rods 12 are fixedly connected to the inner wall of base box 1. This allows movable sleeve 10 to move only up and down along lead screw 9. The cored hollow tube 11, fixedly connected to the upper surface of movable sleeve 10, rises with movable sleeve 10 and is inserted into the apple. As it continues to rise, the apple core enters the cored hollow tube 11 and is located on the surface of ejection ring 13. Then, the operator reverses the drive motor 8, which drives the cored hollow tube 11 to descend. When piston rod 14 is in contact with the base box 1... When the inner bottom wall is in contact, the cored hollow tube 11 is compressed. As the ejector ring 13 slides inside the cored hollow tube 11, the cored hollow tube 11 will push the ejector ring 13 to move upward. The upward movement of the ejector ring 13 automatically pushes the apple core out of the cored hollow tube 11, making it convenient for personnel to remove and clean. The peeling device body 2 is a Starfrit electric apple peeler, which uses an electric motor to drive the peeling mechanism. After the apple is placed in the working area of the peeler, the motor drives the peeling blade to move along the circumference of the apple. The blade contacts the surface of the apple and peels off the outer skin. The speed of the motor or the cutting depth of the blade can be adjusted to adapt to different varieties and skin hardness of apples.
[0027] The bottom end of the screw 6 is rotatably connected to the inner bottom wall of the limiting slide groove 4. When the screw 6 rotates, the lower pressure plate 5 will move up and down along the screw 6 due to the threaded connection. The limiting slide groove 4 restricts the movement direction of the lower pressure plate 5 to prevent it from deviating and ensures that the lower pressure plate 5 can accurately press the apple.
[0028] The top end of the lead screw 9 is rotatably connected to the inner wall of the base box 1. Since the lead screw 9 is threadedly connected to the movable sleeve 10, the rotation of the lead screw 9 will cause the movable sleeve 10 to move up and down along the lead screw 9. The rotatable connection at the top end of the lead screw 9 ensures the stability of the rotation of the lead screw 9, thereby ensuring the accuracy of the movable sleeve 10 in driving the coreless hollow tube 11 to move up and down.
[0029] Both ends of the limiting rod 12 are fixedly connected to the inner wall of the base box 1. When the movable sleeve 10 moves up and down with the rotation of the lead screw 9, the limiting rod 12 restricts the movement direction of the movable sleeve 10, so that it can only move up and down along the lead screw 9, preventing the movable sleeve 10 from rotating or deviating.
[0030] A sealing cover plate 15 is hinged to the surface of the base box 1.
[0031] Both the base box 1 and the peeling device body 2 have slots on their surfaces that are adapted to the coreless tube 11. During the coreless process, the coreless tube 11 needs to rise and fall. These slots provide space for the movement of the coreless tube 11, ensuring that the coreless tube 11 can be smoothly inserted into and removed from the apple without being obstructed by the surfaces of the base box 1 and the peeling device body 2.
[0032] The surface of the positioning frame 3 is provided with a limiting groove 4, and the lower pressure plate 5 is slidably connected to the inside of the limiting groove 4.
[0033] The implementation principle of a cored apple peeler in this embodiment is as follows: First, the operator places the apple to be peeled and cored on the surface of the peeling device body 2. At this time, the peeling device body 2 begins to peel the apple. After peeling, the operator rotates the knob 7, which drives the screw 6 to rotate. Because the screw 6 is threadedly connected to the lower pressure plate 5 and the bottom end of the screw 6 is rotatably connected to the inner bottom wall of the limiting slide groove 4, the lower pressure plate 5 slides in the limiting slide groove 4. Therefore, the rotation of the screw 6 causes the lower pressure plate 5 to descend along the positioning frame 3, thereby pressing the apple and ensuring the stability of the apple in the subsequent core removal process. Next, the operator starts the drive motor 8. Since the output end of the drive motor 8 is fixedly connected to the lead screw 9, and the top end of the lead screw 9 is rotatably connected to the inner wall of the base box 1, and the lead screw 9 is threadedly connected to the movable sleeve 10, with limiting rods 12 passing through both sides of the movable sleeve 10, when the drive motor 8 drives the lead screw 9 to rotate, the movable sleeve 10 will move upward along the lead screw 9. The upper surface of the movable sleeve 10 is fixedly connected to the core removal mechanism. As the movable sleeve 10 rises, the core tube 11 is inserted into the apple. During this continuous rise, the apple core enters the core tube 11 and lies on the surface of the ejector ring 13. Then, the operator reverses the drive motor 8, causing the core tube 11 to descend. When the piston rod 14 contacts the inner bottom wall of the base box 1, the core tube 11 is compressed. Because the ejector ring 13 slides inside the core tube 11, the core tube 11 pushes the ejector ring 13 upwards. The upward movement of the ejector ring 13... The automatic core ejection device removes the apple core from the hollow core tube 11, facilitating easy removal and cleaning. Throughout the operation, the slots on the surfaces of the base box 1 and the peeling device body 2, which are adapted to the core removal hollow core tube 11, provide space for the movement of the core removal hollow core tube 11, ensuring that the core removal hollow core tube 11 can be smoothly inserted into and removed from the apple. The limiting groove 4 on the surface of the positioning frame 3 ensures that the lower pressure plate 5 can accurately press or release the apple. Personnel can then open the sealing cover 15 to remove and clean the ejected apple core.
[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
