Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vegetable processing, and in particular to a vacuum packaging device for dehydrated vegetables. Background Art
[0002] Whether dehydrated vegetables are made by freeze-drying, air-drying or puffing, the finished products are brittle and fragile. During the packaging and transportation process, different degrees of fragments or debris will appear. Before packaging, whether it is in strips or boxes, a hopper is required to put the dehydrated vegetables into the hopper and control the opening and closing of the hopper to control the discharge. Vegetables with smaller particle size may sink to the bottom due to the effect, which may cause more small-particle dehydrated vegetables in some packages, affecting consumer choices and then affecting normal sales. Therefore, how to deal with dehydrated vegetables with different particle sizes is the key to reasonable packaging.
[0003] Existing vacuum packaging devices include semi-automatic and fully automatic packaging devices. Semi-automatic packaging machines require a human to place the bagged or boxed vegetables to be vacuum-packed in a processing area. The packaging machine then creates a vacuum chamber within the processing area, evacuating the vegetable bags or boxes. A hot melt mechanism is then controlled to heat-seal the bag or box at its opening, preserving the vacuum. Fully automatic packaging machines simultaneously include the following processes: vegetable particle transport, bagging, bag sealing, and boxing. Furthermore, when dehydrated vegetables of varying particle sizes need to be accommodated—that is, when each bag contains dehydrated vegetables of varying particle sizes—existing fully automatic packaging machines cannot accommodate both, and their structure is complex.

[0026] Whether dehydrated vegetables are made by freeze-drying, air-drying or puffing, the finished products are brittle and fragile. During the packaging and transportation process, different degrees of fragments or debris will appear. Before packaging, whether it is in strips or boxes, a hopper is required to put the dehydrated vegetables into the hopper and control the opening and closing of the hopper to control the discharge. Vegetables with smaller particle size may sink to the bottom due to the effect, which may cause more small-particle dehydrated vegetables in some packages, affecting consumer choices and then affecting normal sales. Therefore, how to deal with dehydrated vegetables with different particle sizes is the key to reasonable packaging.
[0027] Existing vacuum packaging devices include semi-automatic and fully automatic packaging devices. Among them, the semi-automatic packaging machine requires manual placement of bagged or boxed vegetables to be vacuum-packed in the processing area, and the packaging machine generates a vacuum chamber in the processing area, so that the vegetable bag or vegetable box in the vacuum chamber is evacuated, and then the hot melt mechanism is controlled to hot-melt seal the sealing part of the packaging bag or packaging box to retain the vacuum of the packaging bag and packaging box; the fully automatic packaging machine includes the following processes at one time: vegetable particle transmission, bagging, bag opening sealing, boxing, etc. Then, when it is necessary to take into account dehydrated vegetables of different particle sizes, that is, when dehydrated vegetables of different particle sizes need to be set in each packaging bag, the existing fully automatic packaging machine cannot take into account both, and the structure of the equipment is complicated. Therefore, the embodiment of the present utility model provides a dehydrated vegetable vacuum packaging device, which can package the bagged dehydrated vegetables with different particle sizes separately or mix them to solve the problems in the aforementioned prior art.
[0028] See Figures 1 to 3 As shown, the utility model provides a dehydrated vegetable vacuum packaging device, comprising a chain transmission mechanism 1, a screening mechanism 2, and a packaging mechanism 3. The discharge end of the chain transmission mechanism 1 is docked with the feed port of the screening mechanism 2, and the discharge port of the screening mechanism 2 is docked with the feeding end of the packaging mechanism 3. The multiple discharge ports of the screening mechanism 2 discharge dehydrated vegetables of different particle sizes and move horizontally at a preset speed for transmission; the chain transmission mechanism 1 comprises a plurality of mutually matching arc-shaped conveying chains, and the bottom of the arc-shaped conveying chain is provided with a driving mechanism. Chain, adjacent drive chains are rotatably connected; the packaging mechanism 3 includes a mechanical turntable, a discharge mechanism 4 and a vacuum component, the mechanical turntable includes a mechanical clamp, and the mechanical turntable rotates according to a preset angle to include a bag taking position 31, a bag opening position 32, a discharge position 33, a sealing strip position 34, a sealing position and a discharge position 35 respectively arranged on the circumference of the mechanical turntable, the discharge mechanism 4 is arranged directly above the discharge position 33, and the vacuum component is arranged on the side of the discharge mechanism 4, and is configured to suck the air in the packaging bag.
[0029] In the vacuum packaging device provided by the present invention, the screening mechanism 2 is used to vibrate and transport dehydrated vegetables of different particle sizes to the packaging mechanism 3 using a transmission mechanism, thereby realizing separate packaging or mixed packaging of dehydrated vegetables of different particle sizes, and solving the problem in the prior art that the dehydrated vegetables in the packaging belt are uneven due to different particle sizes, thus affecting sales.
[0030] Among them, the aforementioned sealing position in the embodiment also includes being set at the same position as the sealing strip position 34, that is, the packaging bag can be closed during the process of sticking the strip; of course, if the sealing strip position 34 cannot complete the sealing action of the packaging bag, the two can be set separately, and this embodiment does not impose specific restrictions on this.
[0031] It should be noted that the aforementioned screening mechanism 2 includes a plurality of layered mesh plates 23, and the middle of the upper and lower mesh plates 23 includes: a special-shaped driving wheel 21 and a driven block 22, the special-shaped driving wheel 21 includes a plurality of teeth, the driven block 22 is arranged at the upper and lower ends of the special-shaped driving wheel 21 and the teeth thereon are used to engage with the teeth of the special-shaped driving wheel 21; the driven block 22 arranged at the upper end is connected to the bottom of the mesh plate 23, and the driven block 22 at the lower end is connected to the bottom of the mesh plate 23 through a connecting rod 24; the mesh diameters of the mesh plates 23 of adjacent layers are different.
[0032] like Figure 4 As shown, a vibrating mechanism for the mesh plate 23 is provided, utilizing the rotation of two special-shaped driving wheels 21. Because the teeth on the special-shaped driving wheels 21 mesh with the teeth on the driven block 22, the mesh plate 23 connected to the upper driven block 22 is moved left and right under the rotation of the special-shaped driving wheels 21. After rotating to mesh with the lower driven block 22, the connecting rod 24 pushes the mesh plate 23 connected thereto to move left and right. This continuous reciprocating movement allows the dehydrated vegetable particles on the mesh plate 23 to be screened. As the mesh plate 23 moves downward, the size of the mesh holes on the mesh plate 23 gradually decreases.
[0033] The aforementioned connecting rod 24 includes: a first connecting rod and a second connecting rod. The first connecting rod is connected to the driven block 22 at the lower end, and the second connecting rod is connected to the bottom of the mesh plate 23. The first connecting rod and the second connecting rod are vertically fixed.
[0034] In addition, the aforementioned vacuum assembly is the existing vacuum pump and suction tube. After the dehydrated vegetables are placed in the packaging bag and the sealing strip is affixed, the suction tube penetrates into the packaging bag to extract the air in the bag, thereby achieving vacuum sealing of the packaging bag. The specific structure and installation of the vacuum pump are not specifically restricted here.
[0035] It should also be noted that the dehydrated vegetable vacuum packaging device provided by the present invention also includes multiple vibrating feed trays, the feeding ends of the multiple vibrating feed trays are respectively connected to the discharge ports of different mesh plates 23, and the discharge ends of the vibrating feed trays are connected to different hoppers of the discharge mechanism 4, and the vibrating feed trays are transported back and forth in the horizontal direction at a preset rate.
[0036] In this embodiment, a vibrating tray conveys the sieved dehydrated vegetables to the discharge mechanism 4. Compared to existing conveyor belts, this tray reduces the adhesion of dehydrated vegetable particles to the conveyor belt, thereby increasing friction between the dehydrated vegetables and the conveyor belt and reducing transmission resistance. Furthermore, the vibrating tray is configured to reciprocate horizontally, generating horizontal vibrations in the dehydrated vegetables, which in turn vibrate and convey the dehydrated vegetable particles to the discharge mechanism 4. Compared to existing vertical vibration mechanisms, which continuously vibrate the dehydrated vegetables in a vertical direction, this horizontal movement reduces the impact force between the dehydrated vegetables and the tray, thereby protecting the dehydrated vegetables from damage.
[0037] It should be noted that in this embodiment, the discharge cone of the discharge mechanism 4 discharges the vegetables during its upward movement and is configured to descend to a predetermined height at the bottom of the packaging bag. Discharging the vegetables during movement prevents the dehydrated vegetables from falling directly into the packaging bag at the bag opening, causing the vegetables to collide with each other and damage some of the fragile dehydrated vegetables. This effectively prevents secondary damage to the dehydrated vegetables during bagging and increases the integrity of the packaged dehydrated vegetables.
[0038] In some embodiments, the sealing strips attached to the inner surface of the packaging bag include a Type A sealing strip and a Type B sealing strip, with the Type A sealing strip and the Type B sealing strip being offset and pressed together. The mechanical grippers heat the back surfaces of the Type A and Type B sealing strips and adhere them to the inner wall of the packaging bag. The design of these sealing strips is similar to existing sealing structures and will not be further described in this embodiment.
[0039] In some embodiments, the vibration mechanism of the majority of the mesh plates 23 in the aforementioned screening mechanism 2 includes a vertical or horizontal movement mechanism. The mechanism controlling the vibration of the mesh plates 23 can be a vertical or horizontal movement mechanism, the primary purpose of which is to disperse the dehydrated vegetable particles entering the mesh plates 23, facilitating the entry of dehydrated vegetables of varying particle sizes onto different layers of mesh plates 23 for subsequent screening. Of course, the multi-layered mesh plates 23 are also configured to rotate about their center of circle, utilizing centrifugal force to fling the dehydrated vegetables remaining on the mesh plates 23 toward the edges of the mesh plates 23, facilitating their exit from the screening mechanism 2.
[0040] Finally, the present invention provides a dehydrated vegetable vacuum packaging device, comprising a chain transmission mechanism 1, a screening mechanism 2, and a packaging mechanism 3. The discharge end of the chain transmission mechanism 1 is docked with the feed port of the screening mechanism 2, and the discharge port of the screening mechanism 2 is docked with the loading end of the packaging mechanism 3. The multiple discharge ports of the screening mechanism 2 discharge dehydrated vegetables of different particle sizes and transport them horizontally at a preset rate. The packaging mechanism 3 comprises a mechanical turntable, a discharge mechanism 4, and a vacuum assembly. The mechanical turntable comprises a mechanical gripper. The mechanical turntable rotates according to a preset angle to include a bag taking position 31, a bag opening position 32, a discharge position 33, a sealing strip application position 34, a sealing position, and a discharge position 35, which are respectively arranged on the circumference of the mechanical turntable. The discharge mechanism 4 is arranged directly above the discharge position 33, and the vacuum assembly is arranged on the side of the discharge mechanism 4. The present invention achieves uniform packaging of dehydrated vegetables of different particle sizes, while reducing secondary damage to the dehydrated vegetables during the packaging process and increasing the integrity of the dehydrated vegetables.
[0041] The above embodiments merely illustrate the implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
