Description

Technical Field

[0001] This application relates to the field of packaging equipment technology, and more particularly to a packaging device for enoki mushrooms. Background Technology

[0002] Enoki mushrooms are a common edible and medicinal fungus, rich in dietary fiber, amino acids, and various trace elements. However, enoki mushrooms are crisp and tender, making them susceptible to mechanical damage such as squeezing and collisions during transportation, storage, and sales. Packaging can provide cushioning and protection, reducing breakage and damage and maintaining their appearance. However, most existing enoki mushroom packaging is done manually, which means that workers' hands come into direct contact with the mushrooms, easily transferring bacteria, viruses, and other microorganisms from their hands to the product, affecting food safety. Furthermore, manual packaging is relatively slow and has limited production capacity, which cannot meet the needs of large-scale production. Utility Model Content

[0003] The purpose of this invention is to provide a packaging device for enoki mushrooms in order to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows: This application provides a packaging device for enoki mushrooms, including a vertically distributed first conveyor frame and a second conveyor frame, on which a first conveyor belt and a second conveyor belt are respectively installed. The first conveyor belt is located at a height higher than the second conveyor belt, and a discharge hopper is provided on the first conveyor frame and located above the second conveyor belt. The first conveyor belt is used to place materials, and the second conveyor belt is used to place containers that carry the materials. The second conveyor frame is equipped with a film coating component, which includes a support seat and a rotating shaft. The support seat is provided in two sets and is distributed at intervals at both ends of the second conveyor frame. The support seat has a protrusion and a slot. Both ends of the rotating shaft are respectively installed in the slot, and a film roll is sleeved on the rotating shaft. The second conveyor frame is also equipped with a cutting assembly, which includes a first bracket. The first bracket is located on the side of the film-coating component away from the first conveyor frame. A first push rod component is installed on the first bracket. The piston end of the first push rod component passes through the first bracket and is equipped with a support plate. A cutter is provided on the side of the support plate facing the second conveyor belt. Through the cooperation of the first push rod component, the cutter is moved closer to or away from the second conveyor belt.

[0005] In one embodiment, the second conveyor frame is further provided with a film pressing assembly, the film pressing assembly including a second support, the second support being located between the cutting assembly and the film covering component, and a second push rod component being provided on the second support; The piston end of the second push rod component passes through the second bracket and is connected to a placement seat. The placement seat has an opening, and a shaft is installed in the opening. A pressure roller is rotatably mounted on the shaft, and part of the pressure roller is located outside the placement seat. The pressure roller is moved closer to or further away from the second conveyor belt by the cooperation of the second push rod component.

[0006] In one embodiment, the second conveyor frame is further provided with a cutting edge component. Two sets of the cutting edge component are provided and symmetrically distributed at both ends of the second conveyor frame. The cutting edge component includes a receiving support. The portion of the receiving support is located above the second conveyor belt and has a groove. A blade is movably installed inside the slot, with the tip of the blade facing the second conveyor belt.

[0007] In one embodiment, the receiving support includes a fixed seat and a movable seat, with a slot located on the movable seat. The fixed seat has a sliding groove, and a portion of the movable seat is located within the sliding groove. When the movable seat moves relative to the fixed seat along the sliding groove, the blade moves closer to or further away from the fixed seat.

[0008] In one embodiment, a third push rod component is also provided on the second conveyor frame. The piston end of the third push rod component is connected to a limiting plate, and the limiting plate and the discharge hopper form a movable area for the container. The movement area can be expanded or reduced by the cooperation of the third push rod component.

[0009] In one embodiment, the slot has a mounting hole extending to the outside of the movable seat, and the blade has a number of through holes that are spaced apart along the length of the blade. By moving the blade within the slot, the mounting hole is aligned with one of the sets of through holes. When the mounting hole and through holes are aligned and a pin is installed, the blade is fixed to the movable seat.

[0010] In one embodiment, the first conveyor belt has partitions, and a plurality of partitions are provided and spaced apart along the length of the first conveyor belt, with a material placement area formed between two adjacent sets of partitions.

[0011] The advantages or beneficial effects of the above technical solutions include at least the following: This application discloses a packaging device for enoki mushrooms. Two vertically distributed first and second conveyor frames transport materials and containers respectively, allowing the material to fall into the container and move due to a height difference. During this movement, the material passes through a film-coating component and a cutting component. When the container is below the film-coating component, a film roll mounted on a rotating shaft wraps the container from above, and the remaining film is released simultaneously as the container moves. Since the support plate of the cutting component, which houses the cutter, is connected to a first push rod component, the extension and retraction of the first push rod component cuts the film as the container passes over it, thus completing the film sealing of a single container. Through the cooperation of the two conveyor structures, the film-coating component, and the cutting component, packaging operations can be performed with reduced manual intervention, solving the problems of low efficiency and potential hygiene hazards associated with existing manual packaging methods.

[0019] Reference Figures 1-3A packaging device for enoki mushrooms includes a vertically distributed first conveyor frame 1 and a second conveyor frame 2. A first conveyor belt 11 and a second conveyor belt 21 are respectively installed on the first conveyor frame 1 and the second conveyor frame 2. The first conveyor belt 11 and the second conveyor belt 21 are conveyor belts driven by motors in the prior art. The connection structure between the first conveyor belt 11 and the second conveyor belt 21 and the motor is well known to those skilled in the art, so it will not be described in detail in this application. The first conveyor belt 11 is located at a height higher than the second conveyor belt 21. A discharge hopper is provided on the first conveyor frame 1 and located above the second conveyor belt 21. The first conveyor belt 11 is used to place materials, and the second conveyor belt 21 is used to place containers that carry the materials. The first conveyor belt 11 conveys bulk enoki mushrooms, and the materials are accurately dropped into the containers carried by the second conveyor belt 21 through the discharge hopper by utilizing the height difference. The movement speed between the materials and the containers is adjusted by adjusting the movement speed between the first conveyor belt 11 and the second conveyor belt 21. The second conveyor 2 is provided with a film covering component 3. The film covering component 3 includes a support 31 and a rotating shaft 32. The support 31 is provided with two sets and is distributed at intervals at both ends of the second conveyor 2. The support 31 has a protrusion 311 with a slot. The two ends of the rotating shaft 32 are respectively installed in the slot. A film roll is sleeved on the rotating shaft 32. When the container moves to the bottom of the film covering component 3, the film roll on the rotating shaft 32 releases the PE film, and the film covers the container opening, thereby sealing the container. The second conveyor 2 is also equipped with a cutting assembly 4. The cutting assembly 4 includes a first support 41, which is located on the side of the film-coating component 3 away from the first conveyor 1. A first push rod component 42 is installed on the first support 41. The piston end of the first push rod component 42 passes through the first support 41 and is equipped with a support plate 43. A cutter 431 is provided on the side of the support plate 43 facing the second conveyor belt 21. With the cooperation of the first push rod component 42, the cutter 431 is moved closer to or away from the second conveyor belt 21. The film-coated container continues to move to the bottom of the cutting assembly 4. The first push rod component 42 drives the cutter 431 to move downward, cutting the connecting film between the containers and completing the initial sealing of a single container.

[0020] Based on the above structure, the enoki mushroom material to be packaged is placed sequentially on top of the enoki mushroom material, while the container is placed on the second conveyor belt 21. The material moves with the conveyor belt to above the discharge hopper, and falls into the container on the second conveyor belt 21 through the discharge hopper, moving along the movement path of the second conveyor belt 21. When the container filled with enoki mushrooms moves with the second conveyor belt 21 to below the film covering component 3, the top of the container contacts the film roll on the rotating shaft 32. Due to the continuous movement of the container, the film body drives the rotating shaft 32 to rotate along the slot of the support seat 31 under the action of friction. The film roll releases the PE film simultaneously, and the film body naturally covers the container opening, thereby completing the film covering operation of the container. The film-covered container continues to... The container moves to below the cutting assembly 4. At this time, the first push rod assembly 42 receives a trigger signal, and the piston extends rapidly, driving the support plate 43 and the cutter 431 to move downward. The cutter 431 contacts and cuts the connecting film between the containers. Then, the piston of the first push rod assembly 42 retracts, and the cutter 431 resets, completing the initial film sealing of a single container. The cut container is output with the second conveyor belt 21 and enters the subsequent process. This achieves automated packaging of enoki mushrooms through a continuous process of material conveying, container filling, film covering, and film cutting, while reducing manual intervention. This solves the problems of low efficiency and hygiene in the existing manual packaging process, improves processing efficiency, and adapts to the needs of large-scale production.

[0021] In one embodiment, reference is made to Figure 1 and Figure 2 The second conveyor 2 is also provided with a film pressing assembly 5. The film pressing assembly 5 is used to press the packaging film covering the container, remove the air under the film, and ensure that the film is tightly attached to the edge of the container. The film pressing assembly 5 includes a second support 51, which is located between the cutting assembly 4 and the film covering component 3. A second push rod component 52 is provided on the second support 51. The second push rod component 52 adopts a pneumatic push rod or an electric push rod in the prior art. The piston end of the second push rod component 52 passes through the second bracket 51 and is connected to the placement seat 53. The placement seat 53 has an opening, and a shaft 531 is installed in the opening. A pressure roller component 532 is rotatably mounted on the shaft 531. The pressure roller component 532 can be a hot pressure roller in the prior art according to actual processing needs. Part of the pressure roller component 532 is located outside the placement seat 53. With the cooperation of the second push rod component 52, the pressure roller component 532 is moved closer to or away from the second conveyor belt 21. When the film-coated container moves to below the film pressing assembly 5, the second push rod component 52 drives the placement seat 53 and the pressure roller component 532 to move downward until the pressure roller component 532 contacts the packaging film on the surface of the container. As the container continues to move with the second conveyor belt 21, the pressure roller component 532 rolls on the surface of the film, squeezing the air under the film towards the edge of the container, so that the film tightly fits the container opening and edge, improving the sealing performance after packaging.

[0022] In one embodiment, reference is made to Figure 1 , Figure 4 and Figure 5 The second conveyor frame 2 is also provided with a cutting edge component 6. The cutting edge component 6 is used to cut off the excess packaging film on the edge of the container to make the packaging edge neat. Two sets of cutting edge components 6 are provided and symmetrically distributed at both ends of the second conveyor frame 2. The two sets can perform cutting edge operation on both ends of the container. The cutting edge component 6 includes a support 61. The part of the support 61 is located above the second conveyor belt 21 and has a groove 611. A blade 62 is movably installed inside the slot 611. The tip of the blade 62 faces the second conveyor belt 21. When the pressed container moves to below the edge cutting component 6, the excess film at the edge of the container contacts the tip of the blade 62. As the container moves continuously with the conveyor belt, the film and the blade 62 slide relative to each other. The blade 62 cuts the excess film along the edge of the container, removing redundant film at the edge of the packaging, preventing excess film from sticking together, and improving the neatness of the packaging appearance.

[0023] The support 61 includes a fixed seat 612 and a movable seat 613. The slot 611 is located on the movable seat 613. The fixed seat 612 has a sliding groove 6121. Part of the movable seat 613 is located in the sliding groove 6121. When the movable seat 613 moves relative to the fixed seat 6121, the blade 62 moves closer to or further away from the fixed seat 612. The movable seat 613 moves along the sliding groove 6121. When the width of the container increases, the movable seats 613 on both sides move away from the center of the second conveyor belt 21, so that the blade 62 corresponds to the new edge position of the container. When the width decreases, it moves towards the center, thereby realizing the adaptation of the cutting component 6 to containers of multiple specifications without replacing the entire cutting component 6, reducing equipment adaptation costs, and accurately adjusting the cutting position to avoid cutting the container or leaving too much film.

[0024] In one embodiment, reference is made to Figure 1 and Figure 3The second conveyor frame 2 is also equipped with a third push rod component 7. The third push rod component 7 adopts the existing pneumatic push rod or electric push rod. The piston end of the third push rod component 7 is connected to a limiting plate 71. The limiting plate 71 is used to abut against one end of the container. The limiting plate 71 and the discharge hopper form a moving area for the container. Through the cooperation of the third push rod component 7, the moving area can be expanded or reduced. The limiting plate 71 and the discharge hopper cooperate to form a moving area, restricting the left and right movement of the container on the second conveyor belt 21. According to the width of the container, the piston of the third push rod component 7 is controlled to extend and retract. When the width of the container increases, the piston retracts and drives the limiting plates 71 on both sides to move away from the center of the conveyor belt, expanding the moving area. When the width decreases, the piston extends and shrinks the area. After the container enters the moving area, it is restricted to the center position by the limiting plate 71, ensuring that the enoki mushrooms falling from the discharge hopper fall accurately into the container, and the container is always directly facing the film roll of the film covering component 3 when it moves.

[0025] In one embodiment, reference is made to Figure 1 , Figure 4 and Figure 5 The slot 611 has a mounting hole 6111 extending to the outside of the movable seat 613, and the blade 62 has a through hole 621. Several through holes 621 are provided and are spaced apart along the length direction of the blade 62. The arrangement of several through holes 621 can adapt to containers of different sizes and heights. By moving the blade 62 within the slot 611, the mounting hole 6111 is aligned with one of the through holes 621. When the mounting hole 6111 and the through hole 621 are aligned and a pin is installed, the blade 62 is fixed on the movable seat 613. This allows for adjustment of the height of the blade 62 within the slot 611, ensuring precise contact between the blade tip and the container edge. Simultaneously, the position of the blade 62 is fixed. By removing the pin according to the container height, the blade 62 can be moved up and down to match the blade tip height with the container edge height. This achieves precise adjustment of the blade 62's height, preventing the blade 62 from becoming loose during equipment operation and causing cutting edge errors, thus improving cutting edge stability.

[0026] In one embodiment, reference is made to Figure 1 The first conveyor belt 11 has partitions 111. Several partitions 111 are arranged and distributed at intervals along the length of the first conveyor belt 11. A material placement area is formed between two adjacent sets of partitions 111. When feeding manually or automatically, enoki mushrooms according to the pre-set packaging specifications are placed into the placement area formed by two adjacent sets of partitions 111. When the first conveyor belt 11 moves, the enoki mushrooms in each area move synchronously with the conveyor belt. When they reach the top of the discharge hopper, they fall completely into the container below. Each area is conveyed independently, which reduces the stacking or scattering of enoki mushrooms during the conveying process and improves the standardization of the product.
