Description

Technical Field

[0001] The present invention relates to the technical field of packaging machines, and in particular to fully automatic packaging equipment for fruits and vegetables. Background Art

[0002] Fruits and vegetables refer to the general term for vegetables and fruits. They belong to different categories in botany, but they all play an important role in nutrition and health. Fruits and vegetables are an important source of essential vitamins for the human body, such as vitamin C, vitamin A, vitamin K, etc. These vitamins are essential for maintaining good health and are involved in multiple physiological functions, including enhancing immunity, promoting wound healing, improving vision, etc. Each type of fruit and vegetable contains different types and proportions of nutrients, so diversified intake can ensure that we get a variety of different nutrients. In order to facilitate the storage and transportation of fruits and vegetables and facilitate sales, fruits and vegetables are usually packaged.

[0003] A Chinese patent document with announcement number CN210191887U discloses an automatic fruit and vegetable packaging machine, which includes a material conveyor belt, a film conveying roller group, a film folding mechanism, a film edge aggregation mechanism, and a film sealing mechanism. The film folding mechanism bends the packaging film into a U-shape, and the material is conveyed to the film folding mechanism so that the material is placed above the packaging film and moves with the packaging film. The film sealing aggregation mechanism gathers the two edges of the packaging film to wrap the material in the packaging film. The film sealing mechanism seals the edge of the packaging film and cuts and seals the packaging film. The bag making and bagging steps are combined into one, which can ensure that the material is smoothly and effectively wrapped in the packaging bag, with good packaging quality and fast packaging speed. The material conveyor belt can place different types of materials in one production process, and packaging bags of different sizes can be made according to the sizes of different materials for packaging. It has wide applicability and high degree of automation.

[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] like Figures 1 to 8 As shown, the fully automatic fruit and vegetable packaging equipment of the present invention comprises a conveying mechanism 1, a conveying mechanism 2, a reeling mechanism 3, a folding piece 4, a sealing mechanism 5, a shearing and sealing mechanism 6, a separating mechanism 7 and a shielding member 8. The conveying mechanism 1 is used for batch conveying a plurality of celery stalks. The reeling mechanism 3, the folding piece 4, the sealing mechanism 5 and the shearing and sealing mechanism 6 are all connected to the conveying mechanism 2, and the conveying mechanism 1 and the conveying mechanism 2 operate synchronously. The reeling mechanism 3 is used for reeling the packaging film, the folding piece 4 is used for folding the packaging film, and the sealing mechanism 5 is used for sealing the packaging film, so that a plurality of celery stalks are wrapped in the packaging film, and the shearing and sealing mechanism 6 are used for packaging. The mechanism 6 is used for cutting and sealing the packaging film, so as to complete the packaging of multiple celery stalks. The partition mechanism 7 is connected to the conveying mechanism 1, and one end of the partition mechanism 7 extends to the bottom of the edge sealing mechanism 5. After the multiple celery stalks of the same batch are divided into two parts and placed on the conveying mechanism 1, the partition mechanism 7 can separate the two parts of celery to keep the two parts of celery away from the edge sealing part of the packaging film to avoid the celery leaves moving to the edge sealing position of the packaging film and affecting the edge sealing effect of the packaging film. The shielding member 8 is connected to the partition mechanism 7 to shield the celery to avoid affecting the normal operation of the partition mechanism 7.

[0028] like Figure 1 and Figure 2As shown, the conveying mechanism 1 includes a frame 11, a conveying member 12 and side rollers 13. The conveying member 12 is transmission-connected in the frame 11. The conveying member 12 is composed of a conveyor belt, a motor and two transmission rollers. The two transmission rollers are both rotationally connected in the frame 11. The conveyor belt is transmission-connected between the two transmission rollers. The motor is connected to the frame 11. The motor is connected to one of the transmission rollers. Starting the motor can drive the transmission belt and the two transmission rollers to transmit, thereby moving multiple celery to the conveying mechanism 2 2. The side rollers 13 are divided into two groups, and the number of side rollers 13 in each group is set to be multiple. The two groups of side rollers 13 are rotationally connected to the two sides of the inner wall of the frame 11 respectively, so as to reduce the friction between the celery and the inner wall of the frame 11.

[0029] like Figures 1 to 8 As shown, the partition mechanism 7 includes a partition part 71, a pressing member 72 and a blocking member 73. The partition part 71 is connected to the frame 11, and the pressing member 72 and the blocking member 73 are both connected to the partition part 71. The partition part 71 can separate the two parts of celery, and the pressing member 72 can press down the leaf part of the celery to make the leaf part of the celery lower than the edge sealing mechanism 5. The blocking member 73 is used to block the leaf part of the celery after being pressed down, so that the leaf part of the celery is always lower than the edge sealing mechanism 5 before crossing the edge sealing mechanism 5, thereby avoiding the edge sealing effect of the packaging film being affected by the celery leaves moving to the edge sealing position of the packaging film.

[0030] Continue to refer Figures 1 to 8 As shown, two partitions 71 are provided, and the two partitions 71 are respectively connected to the two sides of the frame 11, and the two parts of celery are respectively located on the side away from each other of the two partitions 71. The pressing member 72 includes a pressing part 721, a rotating shaft 722, a gear 723, a telescopic part 724 and a toothed plate 725. The pressing part 721, the rotating shaft 722 and the gear 723 are all provided in two. The two pressing parts 721 are rotatably connected to the two partitions 71 through the two rotating shafts 722. The two pressing parts 721 are arranged in a V shape in the initial state so that the celery can be moved to the bottom of the pressing part 721. The outer surface of the pressing part 721 is smooth, which can reduce the pressure of the pressing part 72 1 friction with the celery leaf part, the two gears 723 are respectively connected to the two rotating shafts 722, the telescopic part 724 is connected between the two partitions 71, the telescopic part 724 is a cylinder with the telescopic end facing upward, the tooth plate 725 is connected to the telescopic end of the telescopic part 724, and the two gears 723 are meshed with the tooth plate 725, the telescopic part 724 is started to drive the tooth plate 725 to move upward, so that the tooth plate 725 and the two gears 723 are meshed for transmission, at this time, the two rotating shafts 722 are driven by the gear 723 to rotate in the opposite direction, and the two pressing parts 721 are reversed until the pressing parts 721 are flipped to a horizontal state, thereby pressing down the leaf part of the celery through the two pressing parts 721.

[0031] Continue to refer Figures 1 to 8As shown, the blocking member 73 includes a transmission shaft 1 731, a transmission shaft 2 732, a blocking belt 733, a driving source 734 and a transmission member 735. The transmission shaft 1 731 is rotatably connected between the two partitions 71. The transmission shaft 2 732 and the blocking belt 733 are both provided in two numbers. The two transmission shafts 2 732 are respectively rotatably connected to the two partitions 71. The blocking belt 733 is provided in two numbers. One end of the two blocking belts 733 is respectively connected to the two transmission shafts 2 732. The other ends of the two blocking belts 733 are both connected to the transmission shaft 1 73 1, the lower surface of the blocking belt 733 and the lower surface of the lower pressing member 72 after being turned over to the horizontal state are located on the same plane, the blocking belt 733 extends to the bottom of the edge sealing mechanism 5, the driving source 734 is connected to one of the partitions 71, the driving source 734 is a motor, the transmission member 735 is connected between the output shaft of the driving source 734 and the transmission shaft 1 731, the transmission member 735 includes a transmission belt and two transmission wheels, the two transmission wheels are respectively connected to the output shaft of the driving source 734 and the transmission shaft 1 731, and the transmission belt is connected between the two transmission wheels.

[0032] Start the driving source 734 to drive the transmission shaft 1 731 to rotate through the transmission member 735, so that the two blocking belts 733 can operate synchronously with the conveying mechanism 1 1 and the conveying mechanism 2 2, and the leaf part of the celery separated from the pressing member 72 contacts the blocking belt 733, and the blocking belt 733 can operate synchronously with the conveying mechanism 1 1 and the conveying mechanism 2 2, so that the blocking belt 733 and the celery can move synchronously to prevent the leaf part of the celery from being worn.

[0033] like Figures 3 to 6 As shown, the tops of the two partitions 71 are each provided with a mounting groove 711, and the inner walls of the mounting grooves 711 are provided with openings 712. The two openings 712 respectively penetrate through the sides of the two partitions 71 away from each other. The shielding member 8 includes two groups of shielding structures, and the two groups of shielding structures are both installed in the two mounting grooves 711. The two groups of shielding structures each include a rotating portion 81, a shielding portion 82 and a resetting portion 83. The rotating portion 81 is rotatably connected in the mounting groove 711, and the resetting portion 83 is connected between the rotating portion 81 and the inner wall of the mounting groove 711. The resetting portion 83 is a torsion spring for driving the rotating portion 81 to reset. The shielding portion 82 is rolled up on the rotating portion 81, and one end of the shielding portion 82 penetrates through the opening 712 and is connected to the pressing member 72. The shielding portion 82 can shield the leaves of the celery to prevent the leaves of the celery from being clamped between the partition 71 and the pressing member 72 when the pressing member 72 is flipped to a horizontal state, thereby preventing the normal transportation of the celery from being affected.

[0034] Before the pressing member 72 presses down on the leaves of the celery, the reset portion 83 is in a force storage state. At this time, the shielding portion 82 shields the angle between the pressing member 72 and the partition portion 71. When the pressing member 72 turns over and presses down on the leaves of the celery, the reset portion 83 drives the rotating portion 81 to rotate and retracts the shielding portion 82 until the pressing member 72 turns over to a horizontal state.

[0035] Working principle: A plurality of celery stalks are divided into two parts and placed on the conveying member 12 at the same time, and the two parts of celery are separated by two partitions 71. When the two parts of celery move to the position of the two pressing members 72, the telescopic part 724 is started to drive the tooth plate 725 to move upward, so that the tooth plate 725 is meshed with the two gears 723 for transmission. At this time, the two rotating shafts 722 are driven by the gear 723 to rotate in the opposite direction, and the two pressing members 721 are flipped in the opposite direction until the pressing members 721 are flipped to a horizontal state, thereby pressing down the leaf part of the celery through the two pressing members 721.

[0036] Before the pressing member 72 presses down on the leaves of the celery, the reset portion 83 is in a force storage state. At this time, the shielding portion 82 shields the angle between the pressing member 72 and the partition portion 71. When the pressing member 72 turns over and presses down on the leaves of the celery, the reset portion 83 drives the rotating portion 81 to rotate and retracts the shielding portion 82 until the pressing member 72 turns over to a horizontal state.

[0037] Start the driving source 734 to drive the transmission shaft 1 731 to rotate through the transmission member 735, so that the two blocking belts 733 operate synchronously with the conveying mechanism 1 1 and the conveying mechanism 2 2, and the leaf part of the celery separated from the pressing member 72 contacts the blocking belt 733, and the blocking belt 733 operates synchronously with the conveying mechanism 1 1 and the conveying mechanism 2 2, so that the blocking belt 733 and the celery move synchronously until the celery enters the packaging film.

[0038] After the packaging film is folded by the folding piece 4, the packaging film is sealed by the edge sealing mechanism 5. After the celery completely passes through the edge sealing mechanism 5, the celery is separated from the blocking belt 733 and finally sheared and sealed by the shearing and sealing mechanism 6.
