Description

Technical Field

[0001] This invention relates to the field of fruit preservation technology, and in particular to a packaging device and method for fruit preservation. Background Technology

[0002] In existing technologies, fruit refers to juicy, edible plant fruits with a predominantly sweet and sour taste, rich in nutrients such as vitamins and dietary fiber. Botanically, fruit refers to the structure developed from the mature ovary of angiosperms, containing seeds, whose core function is to protect the seeds and assist in dispersal (e.g., through animal consumption). In everyday life, fruit generally refers to sweet or sour, juicy, edible plant fruits, such as apples and bananas, which differs from vegetables (such as tomatoes) in biological classification and culinary applications.

[0003] In existing technology, after fruit is packaged in a box, the outside of the box needs to be wrapped with plastic wrap to keep it fresh. However, this is often done manually by workers, which greatly reduces work efficiency over long periods of time.

[0004] Therefore, the present invention proposes a packaging device and method for fruit preservation to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this application is to provide a packaging device and method for preserving fruit, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a fruit preservation packaging device, comprising a hollow base, the packaging device further comprising:

[0007] A support frame, which is fixedly connected to the top of the base;

[0008] The first fixing rod is slidably connected to the top of the support frame;

[0009] The second fixing rod is fixedly connected to the front side of the support frame, and the second fixing rod is located to the right of the first fixing rod;

[0010] Two upright plates are symmetrically and fixedly connected to the top of the base;

[0011] Telescopic tube, which is rotatably connected to the left side of the right vertical plate, and the right end of the inner tube of the telescopic tube penetrates through the right vertical plate;

[0012] Two clamping plates are fixedly connected to the right side of the left vertical plate and the left end of the telescopic tube, with the two clamping plates on opposite sides being far apart from each other.

[0013] The base is equipped with an auxiliary mechanism and a positioning mechanism on its top.

[0014] Preferably, the auxiliary mechanism includes an adjusting plate, an L-shaped plate, a rotating rod, and a movable plate. The adjusting plate is slidably connected to the front side of the support frame and is fixedly connected to the left side of the first fixed rod. The L-shaped plate is slidably connected to the left side of the left upright plate. The rotating rod is rotatably connected to the front side of the L-shaped plate. The movable plate is slidably connected to the top of the support frame and is rotatably connected to the top of the rotating rod.

[0015] Furthermore, the auxiliary mechanism controls the movement of the L-shaped plate. When the L-shaped plate rises, it can push the rotating rod to move. As the rotating rod moves, it can control the moving plate to move to the left. At this time, the movement of the moving plate can assist the adjustment plate in moving.

[0016] Preferably, a first electric actuator is fixedly connected to the bottom of the base, and the output end of the first electric actuator passes through the base and is fixedly connected to the bottom of the L-shaped plate. A first gull spring is fixedly connected to the bottom of the L-shaped plate, and one end of the first spring is fixedly connected to the top of the base.

[0017] Furthermore, when the first electric actuator is in operation, it can control the L-shaped plate to move longitudinally. By setting the first spring, the first spring can assist the L-shaped plate in descending.

[0018] Preferably, a rotating column is rotatably connected to the top of the support frame, and a moving belt is fixedly connected to the right side of the moving plate. One end of the moving belt is fixedly connected to the right side of the adjusting plate, and the moving belt is in contact with the outer wall of the rotating column.

[0019] Furthermore, when the moving plate moves to the left, it can pull the moving belt to move. At this time, the moving belt, guided by the rotating column, can pull the adjusting plate to move to the right.

[0020] Preferably, the positioning mechanism includes a mating frame, a rack, an eccentric wheel, a gear, a contact plate, and a connecting rod. The mating frame is slidably connected to the inner right wall of the base, and the front side of the mating frame extends to the outside of the base. The rack is slidably connected to the top of the base, and the front side of the rack is fixedly connected to the rear side of the mating frame. The eccentric wheel is rotatably connected to the right side of the upright plate located on the right side. The gear is fixedly connected to the right side of the eccentric wheel, and the gear meshes with the rack. The contact plate is slidably connected to the right side of the upright plate located on the right side, and the bottom of the contact plate is in movable contact with the eccentric wheel. The connecting rod is rotatably connected to the front side of the contact plate, and the top of the connecting rod is rotatably connected to the outer wall of the inner tube of the telescopic tube.

[0021] Furthermore, the positioning mechanism moves by controlling the mating frame, which in turn controls the rack to move. As the rack moves, it controls the gear to rotate, and the rotation of the gear assists the eccentric wheel to rotate, guiding the eccentric wheel to contact the contact plate, pushing the contact plate to rise, and thus pushing the connecting rod to move.

[0022] Preferably, the right inner wall of the base is rotatably connected to two guide posts, and the outer walls of the two guide posts are fitted with the same control band, the outer wall of the control band being fixedly connected to the bottom of the mating frame.

[0023] Furthermore, when the control belt rotates, it can conveniently and synchronously control the movement of the mating frame.

[0024] Preferably, a sloping panel is slidably connected to the inner right side of the base, a sliding frame is slidably connected to the inner top of the base, a rotating wheel is rotatably connected to the bottom of the sliding frame, and the rotating wheel is in active contact with the inclined surface of the sloping panel. The top of the sloping panel is fixedly connected to the outer wall of the control belt, and a No. 3 spring is fixedly connected to the front side of the sloping panel, and one end of the No. 3 spring is fixedly connected to the inner right side of the base.

[0025] Furthermore, when the sliding frame moves, it can drive the rotating wheel to contact the inclined surface of the inclined panel, thereby controlling the inclined panel to move backward.

[0026] Preferably, a second electric actuator is fixedly connected to the inner left side of the base, and the output end of the second electric actuator is fixedly connected to the left side of the sliding frame.

[0027] Furthermore, by setting a second electric actuator, the sliding frame can be controlled to move.

[0028] Preferably, a second spring is fixedly sleeved on the outer wall of the inner tube of the telescopic tube, and one end of the second spring is fixedly connected to the right side of the only right vertical plate.

[0029] Furthermore, by setting a second spring, the second spring can push the inner tube of the telescopic tube to return to its original position.

[0030] This invention also proposes a packaging method for preserving fruit, comprising the following steps:

[0031] S1: First, place the washed fruit in the packaging box, while controlling the plastic wrap of the cylindrical packaging to be between the first fixing rod and the second fixing rod;

[0032] S2: Then, the operation is carried out by controlling the first electric actuator. The first electric actuator can push the L-shaped plate to rise, the L-shaped plate can push the rotating rod to move, and the rotating rod can simultaneously push the moving plate to move to the left. At this time, the moving plate can simultaneously pull the moving belt to move and pull the adjusting plate to move to the right.

[0033] S3: The adjustment plate can control the movement of the first fixing rod. At this time, the first fixing rod moves to the right and extends into the plastic wrap, and cooperates with the second fixing rod to achieve the effect of positioning the plastic wrap.

[0034] S4: Then place the fruit-filled packaging box between the two clamping plates. The second electric actuator can push the sliding frame to move to the right. At this time, the sliding frame can drive the rotating wheel to contact the inclined surface of the inclined plate. At this time, the inclined plate can drive the control belt to rotate in a circle. At the same time, the control belt can synchronously drive the mating frame to move forward. At this time, the mating frame can drive the rack to move.

[0035] S5: The rack can control the gear to rotate through the toothed teeth. When the gear rotates, it can synchronously drive the eccentric wheel to rotate, which in turn drives the eccentric wheel to rotate. The eccentric wheel can contact the bottom of the contact plate, thereby pushing the contact plate to rise.

[0036] S6: The contact plate can push the connecting rod to move, thereby pushing the inner tube of the telescopic tube to move to the left to clamp and fix the packaging box;

[0037] S7: Finally, guide the cling film to contact the packaging box, and rotate the packaging box to achieve a fast packaging effect, which is convenient for the work.

[0038] In summary, the technical effects and advantages of this invention are as follows:

[0039] 1. By placing the washed fruit inside the packaging box, and controlling the cling film of the cylindrical packaging between the first fixing rod and the second fixing rod, the first electric push rod can assist the first fixing rod in moving. At this time, the first fixing rod and the second fixing rod cooperate to fix the cling film for easy use later.

[0040] 2. Control the second electric actuator to work. The second electric actuator can control the inner tube of the telescopic tube to move. At this time, the telescopic tube can assist the two clamping plates to move closer to each other, thereby fixing the packaging box. At this time, guide the plastic wrap to contact the packaging box. By rotating the packaging box, the effect of fast packaging can be achieved, which is convenient for work.

[0041] This invention controls the operation of a first electric actuator, which assists the movement of a first fixed rod in coordination with a second fixed rod to control the plastic wrap. Simultaneously, the operation of the second electric actuator allows for stable positioning of the fruit-filled packaging box. At this point, simply rotating the packaging box achieves a rapid packaging effect, simplifying the work, greatly reducing the workload, and avoiding a decrease in overall work efficiency.

[0066] This invention also proposes a packaging method for preserving fruit, comprising the following steps:

[0067] S1: First, place the washed fruit in the packaging box, while controlling the plastic wrap of the cylindrical packaging to be between the first fixing rod 11 and the second fixing rod 12.

[0068] S2: Then, the operation is carried out by controlling the first electric actuator 3. The first electric actuator 3 can push the L-shaped plate 4 to rise. The L-shaped plate 4 can push the rotating rod 6 to move. The rotating rod 6 can simultaneously push the moving plate 7 to move to the left. At this time, the moving plate 7 can simultaneously pull the moving belt 9 to move and pull the adjusting plate 10 to move to the right.

[0069] S3: The adjusting plate 10 can control the first fixing rod 11 to move. At this time, the first fixing rod 11 moves to the right and extends into the plastic wrap, and cooperates with the second fixing rod 12 to achieve the effect of positioning the plastic wrap.

[0070] S4: Then, the packaging box containing the fruit is placed between the two clamping plates 16. The second electric actuator 17 can push the sliding frame 18 to move to the right. At this time, the sliding frame 18 can drive the rotating wheel to contact the inclined surface of the inclined plate 19. At this time, the inclined plate 19 can drive the control belt 22 to rotate in a circle. At the same time, the control belt 22 can synchronously drive the mating frame 23 to move forward. At this time, the mating frame 23 can drive the rack 24 to move.

[0071] S5: The rack 24 can control the gear 26 to rotate through the tooth pattern. When the gear 26 rotates, it can synchronously drive the eccentric wheel 25 to rotate, thereby driving the eccentric wheel 25 to rotate. The eccentric wheel 25 can contact the bottom of the contact plate 27, thereby pushing the contact plate 27 to rise.

[0072] S6: The contact plate 27 can push the connecting rod 28 to move, thereby pushing the inner tube of the telescopic tube 14 to move to the left to clamp and fix the packaging box;

[0073] S7: Finally, guide the cling film to contact the packaging box, and rotate the packaging box to achieve a fast packaging effect, which is convenient for the work.

[0074] Working principle: In actual operation, the washed fruit is placed inside the packaging box, while the cling film of the cylindrical packaging is positioned between the first fixing rod 11 and the second fixing rod 12. At this time, the first electric push rod 3 is activated, pushing the L-shaped plate 4 upwards. As the L-shaped plate 4 moves, it pushes the rotating rod 6, which in turn pushes the moving plate 7 to the left. Simultaneously, the moving plate 7 pulls the moving belt 9. The movement of the moving belt 9 can be guided by the rotating column 8, pulling the adjusting plate 10 to the right. When the adjusting plate 10 moves, it can control the movement of the first fixing rod 11. At this time, the first fixing rod 11 moves to the right and extends into the plastic wrap, cooperating with the second fixing rod 12 to achieve the effect of positioning the plastic wrap. At the same time, the packaging box containing the fruit is placed between the two clamping plates 16. At this time, the second electric push rod 17 works, pushing the sliding frame 18 to the right. The sliding frame 18 can drive the rotating wheel to contact the inclined surface of the inclined plate 19, thereby controlling the inclined plate 19 to move backward. At this time, the inclined plate 19 can drive the control belt 22 to rotate in a ring. When the control belt 22 rotates, it can synchronously drive the mating frame 23 to move forward. As the mating frame 23 moves, it can drive the rack 24 to move. When the rack 24 moves, it can control the gear 26 to rotate through its teeth. When the gear 26 rotates, it can synchronously drive the eccentric wheel 25. The rotation causes the eccentric wheel 25 to rotate. When the eccentric wheel 25 rotates, it can contact the bottom of the contact plate 27, thereby pushing the contact plate 27 to rise. As the contact plate 27 moves, it can push the connecting rod 28 to move, thereby pushing the inner tube of the telescopic tube 14 to move to the left. This allows the two clamping plates 16 to move closer to each other and clamp and fix the packaging box. At this time, the plastic wrap is guided to contact the packaging box, and the packaging box is rotated to achieve a fast packaging effect, which is convenient for work.

[0075] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The rotating rod (6) can simultaneously push the moving plate (7) to move to the left. At this time, the moving plate (7) can simultaneously pull the moving belt (9) to move and pull the adjusting plate (10) to move to the right. S3: The adjustment plate (10) can control the first fixing rod (11) to move. At this time, the first fixing rod (11) moves to the right and extends into the plastic wrap, and cooperates with the second fixing rod (12) to achieve the effect of positioning the plastic wrap. S4: Then, the packaging box containing the fruit is placed between the two clamping plates (16). The second electric push rod (17) can push the sliding frame (18) to move to the right. At this time, the sliding frame (18) can drive the rotating wheel to contact the inclined surface of the inclined plate (19). At this time, the inclined plate (19) can drive the control belt (22) to rotate in a circle. At the same time, the control belt (22) can drive the mating frame (23) to move forward. At this time, the mating frame (23) can drive the rack (24) to move. S5: The rack (24) can control the gear (26) to rotate through the tooth pattern. When the gear (26) rotates, it can synchronously drive the eccentric wheel (25) to rotate, thereby driving the eccentric wheel (25) to rotate. The eccentric wheel (25) can contact the bottom of the contact plate (27), thereby pushing the contact plate (27) to rise. S6: The contact plate (27) can push the connecting rod (28) to move, thereby pushing the inner tube of the telescopic tube (14) to move to the left to clamp and fix the packaging box; S7: Finally, guide the cling film to contact the packaging box, and rotate the packaging box to achieve a fast packaging effect, which is convenient for the work.
