Description

Technical Field

[0001] This utility model relates to the field of peeling device technology, specifically a vacuum peeling device for fruits and vegetables. Background Technology

[0002] Fruits and vegetables are a general term for edible fruits and vegetables, and are a category of food, as opposed to meat. Commonly peeled fruits and vegetables include potatoes and apples, which are typically peeled efficiently using peeling machines. However, these machines have certain drawbacks, such as: the machines are placed directly in the operating room, requiring manual placement or removal of the peeled fruits and vegetables; and the contact with air during peeling leads to oxidation. Utility Model Content

[0003] This utility model mainly provides a vacuum peeling device for fruits and vegetables, which solves the problem that existing peeling machines require manual insertion or removal of the fruits and vegetables to be peeled, and that the fruits and vegetables are easily oxidized during the peeling process due to contact with air.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A vacuum peeling device for fruits and vegetables includes a material rotating mechanism with a material insertion rod and a rotating peeling mechanism; it includes a peeling chamber, and two material chambers symmetrically arranged on both sides of the peeling chamber, the material chambers communicating with the peeling chamber, and both the peeling chamber and the two material chambers communicating with a vacuum pump; an external sealing mechanism is provided at the outer end of the material chamber, and an internal sealing mechanism is provided at the inner end of the material chamber; a linear displacement mechanism is provided in the peeling chamber between the two material chambers, a rotating mechanism is provided on the linear displacement mechanism, and the material rotating mechanism is disposed on the rotating mechanism; the rotating peeling mechanism is disposed in the peeling chamber in front of the linear displacement mechanism. The material rotating mechanism with the material insert rod and the rotating peeling mechanism can both adopt any structure from the prior art, as long as they can realize the technical principle of this application. For example, the material rotating mechanism with the material insert rod is mainly used to fix the fruit and vegetable materials that need to be peeled and to drive the fruit and vegetable materials to rotate; the rotating peeling mechanism includes a peeling knife and a turntable on which the peeling knife is installed. The turntable can drive the peeling knife to rotate horizontally around the fruit and vegetable materials, and after the peeling knife is installed on the turntable, it can be displaced outward with the support of the fruit and vegetable materials and fit against the outer wall of the fruit and vegetable materials. At the same time, it fits tightly against the outer wall of the fruit and vegetable materials during the peeling process. Both the material chamber and the peeling chamber are equipped with vacuum pressure gauges with radial screws to monitor their respective vacuum levels. The vacuum equipment can adopt the prior art, as long as it can realize the technical principle of this application. It is connected to each chamber through a vacuum tube, and valves can be installed on the vacuum tube.In use, the two material chambers are divided into an infeed side material chamber and an outlet side material chamber. Initially, both the external and internal sealing mechanisms of the channels in both material chambers are closed. The vacuum equipment is then activated to evacuate the peeling chamber and the outlet side material chamber until the vacuum level stabilizes within a preset threshold. The vacuum equipment is then turned off while maintaining the vacuum state in both the outlet side material chamber and the peeling chamber. When peeling fruits and vegetables is required, the external sealing mechanism of the infeed side material chamber is opened, and multiple fruits and vegetables to be peeled are placed into the infeed side material chamber. After placement, the external sealing mechanism of the infeed side material chamber is closed, and the vacuum equipment is used to evacuate the infeed side material chamber. The material chamber on the feed side is evacuated until the vacuum level matches that of the peeling chamber. Then, the sealing mechanism inside the channel of the material chamber on the feed side is opened, and the rotating mechanism is started to drive the material rotating mechanism to rotate, so that the material insertion rod of the material rotating mechanism is aligned with the center of the material in the material chamber on the feed side. The linear displacement mechanism is started to drive the material insertion rod to be peeled into the material to be peeled. After insertion and fixing, the linear displacement mechanism drives the material rotating mechanism and the material to reset and return to the center position of the peeling chamber. Then, the sealing mechanism inside the channel of the material chamber on the feed side is closed. The rotating mechanism drives the material insertion rod and the material to be peeled to rotate and abut against the inside of the peeling blade of the rotating peeling mechanism. The material rotation mechanism is activated, causing the material to rotate. Simultaneously, the peeling mechanism is activated, causing the peeling blade to revolve horizontally around the material. Through the coordination of rotation and revolution, the peeling blade cuts along the material surface, removing the outer skin. After peeling, the position of the peeling mechanism remains unchanged (it does not reset). The rotation mechanism drives the material rotation mechanism and the peeled material to rotate 180°, aligning the material with the discharge side material cavity. The sealing mechanism inside the discharge side material cavity is opened, and the linear displacement mechanism is activated, moving the material towards the discharge side material cavity and feeding the peeled material into it. Then, the material is discharged through a certain degree of repositioning. The sealing mechanism inside the channel on this side, even if it internally limits the material after peeling, does not affect the retraction of the material insert rod driven by the linear displacement mechanism. The linear displacement mechanism is activated to retract the material insert rod until the material is completely detached from it, and then the sealing mechanism inside the channel seals the material cavity on the discharge side. When it is necessary to remove the peeled material, the external sealing mechanism of the material cavity on the discharge side is opened, the air pressure inside the cavity is balanced, and the material is removed. After removing the material, the external sealing mechanism of the discharge side is closed, and the vacuum equipment is restarted to evacuate the material cavity on the discharge side, restoring the initial vacuum state. The aforementioned steps are repeated for the next peeling operation, achieving uninterrupted vacuum peeling through continuous feeding on the infeed side and continuous discharge on the outlet side.This structure, with its symmetrically arranged dual material chambers and corresponding sealing and vacuuming mechanisms, prevents disruption of the vacuum environment in the peeling chamber, maintaining a constant vacuum during operation. This effectively prevents oxidation of fruits and vegetables during peeling. Furthermore, the reduced adhesion between the fruit and vegetable surface and the pulp in the vacuum environment allows the peeling blade to cut close to the surface, minimizing material loss. It eliminates the need for hot water or chemical reagents, effectively preserving the nutrients and flavor of the fruits and vegetables. Multiple fruits and vegetables can be placed in the infeed chamber or stored in the outlet chamber. The linear displacement mechanism moves the material insertion rod, and the sealing mechanism in the outlet channel facilitates the retrieval of fruits and vegetables, eliminating manual loading and unloading processes, preventing interference with the vacuum peeling process, and reducing labor intensity.

[0005] Furthermore, the linear displacement mechanism includes a frame disposed within the peeling cavity, a guide rod and a screw rotatably connected between two frames, and a first motor for driving the screw to rotate on any of the frames. A displacement seat is slidably connected to the guide rod and threadedly connected to the screw; the rotation mechanism is disposed on the displacement seat. The first motor can employ existing technology, such as a servo motor. In use, the first motor drives the screw to rotate forward and backward, and the displacement seat moves along the guide rod towards the material cavities on the feeding and discharging sides. This structure, through the guide rod and screw, effectively prevents the displacement seat from shifting or wobbling during movement, ensuring that the material insert always aligns with the center of the material in a straight line; and the screw drive has high precision and high stability characteristics. Combined with the controllable speed of the first motor, the displacement speed and distance can be flexibly adjusted according to the size of the material, adapting to the insertion needs of fruits and vegetables of different diameters.

[0006] Furthermore, the rotating mechanism includes a second motor rotatably connected to the displacement seat. The upper end of the second motor extends through the displacement seat and is fitted with a mounting base. Multiple bullseye balls are annularly mounted on the upper end of the displacement seat to support the lower side of the mounting base. The second motor can be any existing technology that achieves the technical principles of this application, such as a stepper motor, which enables precise angle control. In use, the second motor drives the mounting base rotation rod, and the bullseye balls support the lower side of the mounting base. Using this mechanism, the second motor drives the mounting base to rotate. During rotation, the annularly distributed bullseye balls provide uniform support to the mounting base, effectively distributing the weight of the mounting base and materials, preventing the mounting base from tilting due to unilateral force. Simultaneously, the rolling friction resistance of the bullseye balls is extremely low, reducing the load on the second motor, lowering energy consumption, and extending motor life.

[0007] Furthermore, the channel external sealing mechanism includes a cover detachably connected to the outer end of the material chamber, and the cover is provided with an external sealing ring that mates with the material chamber. The cover can be detachably connected to the outer end of the material chamber using any existing method. In use, the cover is opened to allow the material to be peeled to be placed into the material chamber or to remove the peeled material; when closed, the cover is tightly fitted to the material chamber port via the external sealing ring. This structure, with its excellent sealing performance using the external sealing ring, ensures that the material chamber can quickly reach the preset vacuum level; the detachable connection method is convenient to operate, requiring no complex tools to open and close the cover, reducing the labor intensity of operators, and facilitating subsequent cleaning, maintenance, or replacement of the material chamber interior and the external sealing ring.

[0008] Furthermore, the sealing mechanism within the channel includes a first electric push rod disposed within the peeling chamber. An inner platform is located at the upper end of the first electric push rod. A sealing plate is mounted on the inner platform facing the inner end of the material chamber via an elastic guide. An inner sealing ring that mates with the material chamber is mounted on the sealing plate. A second electric push rod is disposed within the peeling chamber. A U-shaped pusher is located at the end of the second electric push rod. Pushing areas that mate with the U-shaped pusher are located on both sides of the sealing plate. Specifically, the elastic guide includes a crossbar mounted on the sealing plate and a spring disposed between the sealing plate and the inner platform. The spring is primarily used to pull the sealing plate back to its original position. After the sealing plate is displaced by the second electric push rod, it needs to be pulled away from the inner wall of the peeling chamber or the inner end of the material chamber by the spring. The crossbar is slidably connected to the inner platform. In use, the first electric push rod can move the sealing plate closer to or further away from the material chamber port, initially controlling the opening and closing of the channel. The second electric push rod pushes the sealing plate via the U-shaped pusher, achieving a tight fit of the inner sealing ring. With this structure, the combination of the first electric push rod and the elastic guide can achieve flexible docking of the sealing plate. The elastic guide can buffer the contact pressure between the sealing plate and the material chamber port, ensuring that the inner sealing ring always fits and seals. Furthermore, the secondary push of the second electric push rod can further enhance the sealing performance. Especially in a vacuum environment, the U-shaped pusher can apply uniform pressure to both sides of the sealing plate to prevent gaps from appearing in the inner sealing ring due to vacuum negative pressure, ensuring vacuum isolation between the peeling chamber and the material chamber, and preventing air from entering the peeling chamber when one side of the material chamber is opened or closed.

[0009] Beneficial effects: The symmetrically arranged dual material chambers, along with corresponding sealing mechanisms and vacuum equipment, prevent damage to the vacuum environment in the peeling chamber, maintaining a constant vacuum during operation. This effectively prevents oxidation of fruits and vegetables during peeling. Furthermore, the reduced adhesion between the fruit and vegetable surface and the pulp in a vacuum environment allows the peeling blade to cut close to the surface, minimizing material loss. No hot water or chemical reagents are needed, effectively preserving the nutrients and flavor of the fruits and vegetables. Multiple fruits and vegetables can be placed in the infeed chamber or stored in the outlet chamber. The linear displacement mechanism moves the material insertion rod, and the sealing mechanism in the outlet channel facilitates the retrieval of fruits and vegetables, eliminating manual loading and unloading processes, preventing interference with the vacuum peeling process, and reducing labor intensity.

A first motor 7 for driving the screw 6 to rotate is disposed on any one of the stands 5. A displacement seat 8 is slidably connected to the guide rod, and the displacement seat 8 is threadedly connected to the screw 6. The rotation mechanism is disposed on the displacement seat 8. The rotation mechanism includes a second motor rotatably connected within the displacement seat 8. The upper end of the second motor extends through to the outside of the displacement seat 8 and is provided with a mounting base 9. A plurality of bullseye balls 10 for supporting the lower side of the mounting base 9 are annularly mounted on the upper end of the displacement seat 8. The channel external sealing mechanism includes a cover 11 detachably connected to the outer end of the material cavity 4. An external sealing ring that fits the material cavity 4 is disposed on the cover 11. The sealing mechanism within the channel includes a first electric push rod 12 disposed within the peeling cavity 3. An inner platform 13 is provided at the upper end of the first electric push rod 12. A sealing plate 14 is provided on the inner side of the inner platform 13 facing the inner end of the material cavity 4 via an elastic guide. An inner sealing ring that mates with the material cavity 4 is provided on the sealing plate 14. A second electric push rod 15 is disposed within the peeling cavity 3. A U-shaped push frame 16 is provided at the end of the second electric push rod 15. Pushing areas that mate with the U-shaped push frame 16 are provided on both sides of the sealing plate 14.

[0015] In use, the two material chambers 4 are divided into an infeed side material chamber and an outlet side material chamber. Initially, both the external and internal sealing mechanisms of the channels in both material chambers 4 are closed. The vacuum equipment is activated to evacuate the peeling chamber 3 and the outlet side material chamber 4 until the vacuum level stabilizes within a preset threshold. Then, the vacuum equipment is turned off while maintaining the vacuum state in the outlet side material chamber 4 and the peeling chamber 3. When peeling fruits and vegetables is required, the external sealing mechanism of the infeed side material chamber 4 is opened, and multiple fruits and vegetables to be peeled are placed into the infeed side material chamber 4. After placement, the external sealing mechanism of the infeed side material chamber 4 is closed, and the vacuum equipment is used to evacuate the infeed side material chamber 4 until the vacuum level is consistent with that of the peeling chamber 3. Then, the internal sealing mechanism of the infeed side material chamber 4 is opened, and the rotating mechanism is activated to rotate the material rotating mechanism 1, aligning the material insertion rod of the material rotating mechanism 1 with the infeed side material chamber 4. The material is centered within the material; the linear displacement mechanism is activated to insert the material insert rod into the material to be peeled; after insertion and fixing, the linear displacement mechanism drives the material rotation mechanism 1 and the material to reset, returning to the center position of the peeling chamber 3; then the sealing mechanism inside the channel of the material chamber 4 on the feeding side is closed; the rotating mechanism drives the material insert rod and the material to be peeled to rotate, and they are placed against the inner side of the peeling knife of the rotating peeling mechanism 2; the material rotation mechanism 1 is activated to drive the material to rotate, and at the same time the rotating peeling mechanism 2 is activated to drive the peeling knife to revolve horizontally around the material. Through the cooperation of rotation and revolution, the peeling knife cuts along the surface of the material to remove the outer skin; after peeling is completed, the position of the rotating peeling mechanism 2 is kept unchanged, that is, it is not reset. The rotating mechanism drives the material rotation mechanism 1 and the peeled material to rotate 180°, so that the material is aligned with the material chamber 4 on the discharge side; the sealing mechanism inside the channel of the material chamber 4 on the discharge side is opened, the linear displacement mechanism is activated to drive the material to move towards the material chamber 4 on the discharge side, and the peeled material is sent into the material chamber 4 on the discharge side. The process begins with resetting the sealing mechanism inside the discharge side channel to a certain extent. Even if the sealing mechanism inside the channel limits the material inside after peeling, it does not affect the material insertion rod's retraction under the drive of the linear displacement mechanism. The linear displacement mechanism is then activated to retract the material insertion rod until the material is completely removed from the material insertion rod. Subsequently, the inner end of the discharge side material chamber 4 is sealed by the channel sealing mechanism. When it is necessary to remove the peeled material, the outer sealing mechanism of the discharge side material chamber 4 is opened, and the material is removed after balancing the air pressure inside the chamber. After removing the material, the outer sealing mechanism of the discharge side channel is closed, and the vacuum equipment is restarted to evacuate the discharge side material chamber 4, restoring the initial vacuum state. The aforementioned steps are repeated for the next peeling operation, with continuous feeding from the infeed side and continuous discharge from the discharge side, achieving uninterrupted vacuum peeling.This structure, with its symmetrically arranged dual material chambers 4 and corresponding sealing mechanisms and vacuum equipment, prevents disruption of the vacuum environment in the peeling chamber 3, maintaining a constant vacuum during operation. This effectively prevents oxidation of fruits and vegetables during peeling. Furthermore, the reduced adhesion between the fruit and vegetable surface and the pulp in a vacuum environment allows the peeling blade to cut close to the surface, minimizing material loss and eliminating the need for hot water or chemical reagents, thus preserving the nutrients and flavor of the fruits and vegetables. Multiple fruits and vegetables can be placed in the infeed chamber 4 or stored in the discharge chamber 4. The linear displacement mechanism moves the material insertion rod, and the sealing mechanism in the discharge channel retrieves the fruit and vegetable materials, eliminating manual loading and unloading processes, preventing interference with the vacuum peeling process, and reducing labor intensity. Figure 1 shows a portion of the peeling chamber 3 cut out for internal structure visualization.
