For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] like Figure 1 — Fig.18 The embodiment shown.

[0044] A vertical mesh bag machine comprises a frame 1, on which a first fixed plate 31 is fixedly mounted, a rotating disk 32 is rotatably mounted on the bottom surface of the first fixed plate 31, a plurality of mesh bag sleeves 33 evenly distributed with mesh bags are fixedly mounted on the bottom surface of the rotating disk 32, and a rotating drive motor 35 for driving the rotating disk 32 to rotate is fixedly mounted on the first fixed plate 31.

[0045] See also Figure 1 and Figure 4 As shown, when the mesh bag on one of the mesh bag sleeves 33 is used up, the rotating drive motor 35 drives the rotating disk 32 to rotate, thereby driving another mesh bag sleeve 33 with a mesh bag on the rotating disk 32 to move to the loading and packaging position, thereby realizing automatic replacement of the mesh bag. During this process, no human intervention or shutdown operation is required, thereby greatly improving the packaging efficiency.

[0046] In the present application, the mesh bag sleeve 33 is a hollow cylinder, which is installed on the lower surface of the rotating disk 32 through the top and bottom, and the cylindrical mesh bag is sleeved on the outer surface of the mesh bag sleeve 33 (see Fig.17 As shown), the mesh bag is pulled downward from the outer surface of the mesh bag sleeve 33 by the bag pulling assembly 5 described below to achieve bag loading. The product enters the hollow hole of the mesh bag sleeve 33 from the loading position and falls into the mesh bag from the hollow hole. At this time, the opening below the mesh bag is closed, and the loading of the product is completed. The product here can be agricultural and sideline products such as vegetables, fruits, etc., or other types of products. The specific product type is not limited here.

[0047] In this embodiment, there are two mesh bag sleeves 33 which are evenly spaced and installed on the bottom surface of the rotating disk 32. In practice, the number and diameter of the mesh bag sleeves 33 can be set as needed, and the specific number and size are not limited here.

[0048] In this embodiment, the rotary drive motor 35 drives the rotary disk 32 to rotate by belt transmission. A reducer can be installed at the power output end of the rotary drive motor 35 as needed. The high speed and low torque of the rotary drive motor 35 can be converted into low speed and high torque through the reducer, thereby meeting the rotation needs of the rotary disk 32.

[0049] A conveyor line 7 for conveying the net bags after product packaging is arranged on the frame 1 directly below the net bag sleeve 33; the first fixed plate 31 is installed with a roller 34 that contacts the rotating disk 32; at least one detection sensor 36 for detecting whether there is a net bag on the net bag sleeve 33 is fixedly installed on the bottom surface of the rotating disk 32.

Under the guidance of the multiple rollers 34, the rotary drive motor 35 drives the rotating disk 32 to rotate more stably. The detection sensor 36 is used to detect whether there is a cylindrical net bag on the net bag sleeve 33. If the detection sensor 36 detects that the net bag does not exist, the process of replacing a new net bag is entered.

[0052] See also Figures 1 to 4 As shown, when packaging the product, the rotating disk 32 is driven by the rotating drive motor 35 to move the mesh bag sleeve 33 with the mesh bag to the discharge port of the feed chute plate 22, so that the product from the feed chute plate 22 can fall into the mesh bag through the hollow hole of the mesh bag sleeve 33, thereby completing the loading of the product; specifically, when in use, the lifting cylinder 23 is first started to drive the baffle 24 to move upward, thereby opening the feed port of the feed chute plate 22. At this time, the product located at the feed port will enter the hollow hole of the mesh bag sleeve 33 through the discharge port, and under the action of gravity, the product falls into the mesh bag located at the bottom of the mesh bag sleeve 33. At this time, the bottom of the mesh bag is in a closed state.

After conveying a certain distance, the downward pressing cylinder 843 drives the downward pressing plate 844 to descend and press down and fix the label papers on both sides of the label cutter 842, and then the cutter cylinder 841 is started to drive the label cutter 842 to move to the position of the avoidance groove 845 to cut the label paper pressed and fixed by the downward pressing plate 844. After the label paper is cut, the cutter cylinder 841 and the downward pressing cylinder 843 are restored to the initial state in turn, and the downward pressing and cutting state are released. In order to make the label paper fit the mesh bag better, air is blown downward through the blowing hole 86 at the label outlet, so that the label paper droops and contacts the mesh bag during the conveying process, and is heat-sealed to the mesh bag through the subsequent mesh bag gathering heat sealing cutting component 6.

[0070] In the present embodiment, there are two groups of mesh bag heat-sealing cutting components 64 arranged on the left and right sides, and are respectively installed on the first sliding plates 62 distributed on the left and right sides. The two groups of mesh bag heat-sealing cutting components 64 have certain differences, which can be recorded as left heat sealing and right heat sealing here. When cutting, only one of the left and right heat sealing has a mesh bag cutter 645, and the other does not have a mesh bag cutter 645, so that the mesh bag is cut by mutual extrusion; correspondingly, only one of the left and right heat sealing blocks 643 has a corresponding sliding rod 642 and a compression spring 644, and the other is fixedly installed on the second sliding plate 641. When heat sealing, the two heat sealing blocks 643 contact to achieve heat sealing. As the contact continues, the compression spring 644 contracts to expose the mesh bag cutter 645 to achieve cutting. It should be noted here that the mesh bag cutter 645, the sliding rod 642 and the compression spring 644 are located on the second sliding plate 641 on the same side.

[0071] A buffer pad 9 is fixedly installed on the upper surface of each gathering plate 631 located above; during heat sealing, the product from the feeding assembly 2 enters the mesh bag through the mesh bag sleeve 33. In order to prevent the product from being bumped under the action of the weight, the buffer pad 9 is used to reduce the degree of damage caused by the bump.

[0072] A clamping structure 10 is provided between each of the mesh bag sleeves 33 and the rotating disk 32, and the mesh bag sleeves 33 are detachably connected to the rotating disk 32 through the clamping structure 10; the clamping structure 10 includes a clamping plate 103 fixedly installed on the top of the mesh bag sleeve 33, and also includes a second fixed plate 101 fixedly installed on the bottom surface of the rotating disk 32, a clamping groove 102 adapted to the clamping plate 103 is formed between the second fixed plate 101 and the rotating disk 32, and a clamping pin 104 that can penetrate into the groove on the side wall of the clamping plate 103 is provided on the side wall of the second fixed plate 101.

[0073] See also Fig.17 As shown, in the present embodiment, the card slot 102 is in a "U" shape, and the card plate 103 slides from the opening of the card slot 102 into the card slot 102 for installation; specifically, when replacing, first the card pin 104 is pulled out from the groove on the side wall of the card plate 103, thereby releasing the limit on the card plate 103. At this time, it is only necessary to remove the card plate 103 from the card slot 102 to complete the disassembly of the mesh bag sleeve 33 and separate it from the rotating disk 32; when a new mesh bag sleeve 33 needs to be replaced, first the card plate 103 is slid into the card slot 102, and then the end of the card pin 104 is inserted into the groove on the side wall of the card plate 103 to position the card plate 103 and prevent the card plate 103 from being separated from the card slot 102.

[0074] The working process of the utility model is as follows: when the upper bag opening of the current mesh bag is heat-sealed and cut off, the two mesh bag gathering components 63 and the two mesh bag heat-sealing and cutting components 64 on both sides are close to each other and are in a heat-sealing and cutting state, and the lower bag opening of the current mesh bag is heat-sealed and closed (see Fig.18 As shown), at this time, the two buffer pads 9 are located at the outlet below the mesh bag sleeve 33, and the lifting cylinder 23 drives the baffle plate 24 to rise and open the inlet, and the product passes through the outlet of the feed chute plate 22 and enters the hollow hole of the mesh bag sleeve 33 to the current mesh bag. During the descent, the buffer pad 9 cushions the descent of the product. After the product falls into the current mesh bag, the feed inlet of the feed component 2 can be closed, and then the mesh bag gathering components 63 and the mesh bag heat sealing and cutting components 64 on both sides deviate from each other, and then the bag pulling component 5 pulls the cylindrical mesh bag on the outer surface of the mesh bag sleeve 33 downward to make the upper bag opening of the current mesh bag Placed between two mesh bag gathering components 63 and two mesh bag heat-sealing and cutting components 64, the label conveying component 8 outputs the label paper printed by the printing tensioning component 4 during the pulling process, and cuts the label paper after outputting a certain distance, then the two mesh bag gathering components 63 move closer to each other and the two mesh bag heat-sealing and cutting components 64 move closer to each other to heat-seal and cut the upper bag opening of the current mesh bag between the two, and heat-seal the label to the mesh bag, thereby realizing the heat-sealing and cutting of the current mesh bag, separating the current mesh bag from the next mesh bag, and then repeating the above operation to heat-seal the next mesh bag.
