Description

Technical Field

[0001] The utility model relates to a packaging machine, in particular to a full-automatic mesh bag packaging machine. Background Art

[0002] At present, in a large part of the fresh-keeping methods during the transportation of vegetables, seafood, etc., ice bottles are used for fresh-keeping. In order to facilitate handling and storage, before freezing, multiple water bottles are usually bagged and grouped for packaging in the domestic ice bottle market. Now, some of the ice bottle market uses the heat shrinkable film packaging machine used in the purified water production line for automatic packaging. This kind of packaging machine has a large power and high consumable cost. The outside of the water bottle uses heat shrinkable film. When the water bottles are bagged and frozen, it takes a long time and consumes a lot of electricity. Therefore, this kind of packaging not only has a high consumable cost, but also increases the production cost of ice bottles. In order to reduce costs, most of the market uses mesh bags to package ice bottles and completes the packaging by manual bagging. Although this kind of packaging method reduces costs, the operation efficiency is low, resulting in an increase in labor costs. Content of the Utility Model

The front part of the feeding support 105 is provided with a horizontal section. The roller group 106 is arranged at the upper end of the horizontal section. A feeding buffer bend floating counterweight pipe 108 is arranged in parallel below the middle of the roller group 106. Sliding rods 109 are arranged in the vertical direction at both ends of the feeding buffer bend floating counterweight pipe 108. The end of the feeding buffer bend floating counterweight pipe 108 is sleeved on the sliding rod 109 and is slidably connected to the sliding rod 109.

[0054] Working principle

[0055] The working process of a fully automatic mesh bag packaging machine includes the following steps:

[0056] The feeding assembly 1 is used to realize the feeding of the mesh bag roll material. The mesh bag roll material is arranged on the roll material roller shaft 102, and the starting end of the roll material is bypassed around one side of the roller group 105, the feeding buffer bend floating counterweight pipe 108, and the other side of the roller group 105 and then sleeved on the bag material opening assembly 2. When feeding, the air clamping assembly 3 is opened to pull a part of the roll material. During the process of pulling the roll material, the feeding buffer bend floating counterweight pipe 108 moves upward along the sliding rod 109 under the action of the pulling force. The photoelectric detection switch 107 detects the rise of the feeding buffer bend floating counterweight pipe 108. At this time, the feeding motor 101 is started, and the roll material roller shaft 102 rotates. The mesh bag material is fed along the slope section, and after being transmitted and guided by the roller group 106, the feeding buffer bend floating counterweight pipe 108 returns to its original position under the action of gravity. After the photoelectric detection switch 107 detects the return of the feeding buffer bend floating counterweight pipe 108, the feeding motor 101 stops rotating. During the rotation of the roll material roller shaft 102, its ends are respectively supported by two roller shaft runners 103, and the roll material roller shaft 102 drives the two roller shaft runners 103 to rotate, thereby realizing the rotational connection between the roll material roller shaft 102 and the roller shaft fixing frame 104.

[0057] Stretching components 15 are provided on both sides of the front end of the feeding component 1. When the mesh bag roll reaches the discharge end of the feeding component 1, the first stretching cylinder 1501 and the second stretching cylinder 1502 are extended, and the two groups of needle cylinders 1503 are extended and inserted into the mesh bag roll. Then the first stretching cylinder 1501 and the second stretching cylinder 1502 are contracted, and the two groups of needle cylinders 1503 flatten the mesh bag roll to facilitate the installation on the bag opening component 2.

[0058] After the mesh bag is delivered to the bag material opening assembly 2, two tensioning spring bars 201 open the mesh bag, and the mesh bag opening is sleeved on the front end of the four guide pieces 204. Under the guidance of the outer guide wheel 203 and the inner guide wheel 205, the mesh bag moves along the guide piece 204 toward the forming piece 207. When the mesh bag moves to the rear side of the forming piece 207, the four air clamp groups in the air clamp assembly 3 clamp the four corners of the mesh bag, and at the same time, the four air clamp groups move forward horizontally. When it moves to a certain distance, the front end of the mesh bag reaches the required position, which is determined according to the required length of the mesh bag. At this time, the wire cutting machine in the cutting assembly 13 cuts the bottom of the mesh bag. The net bag is cut off at the bottom, and after cutting, the air clamp group continues to clamp the net bag and move it forward horizontally until the bottom of the net bag reaches the bag bottom sealing and pressing assembly, and the pressing block group moves downward to press the bottom of the bag material on the bag material sealing support plate, and then the sewing machine group 6 is turned on, and the sewing machine group 6 enters along one side of the bottom of the net bag to sew and seal the entire bottom; after the bottom is sewn, the air clamp group clamps the net bag and continues to move forward horizontally, and is sleeved on the outside of the support bracket assembly 4, and the lifting arm 402 is raised to open the net bag to the required height. At this time, the bottle feeding conveying mechanism 10 conveys the water bottle on its upper part, and the bottle feeding clamp 9 of the bottle feeding forming assembly 9 is 02 extends out, clamps a row of bottles from the bottle feeding conveying mechanism 10 and moves them to the front side of the bottle pushing assembly 5 through the horizontal moving mechanism of the bottle feeding assembly, and then the bottle feeding clamping plate 902 rises under the action of the bottle feeding assembly lifting cylinder and returns to the initial position, and repeats this process until multiple rows of bottles are pushed out to form a group of bottles in a matrix shape, and then the bottle pushing plate of the bottle pushing assembly 5 extends out to push a group of bottles into the support plate bracket assembly 4, and then continues to push, and moves the bottles in the support plate bracket assembly 4 together with the outer mesh bag to the finished product conveying mechanism 7, and the upper support rod group 16 on the front side of the feeding end of the finished product conveying mechanism 7 01 descends, and the lower support rod group 1602 rises, and the bag mouth is supported to the height flush with the upper guide baffle 808 and the lower guide baffle 809. The upper guide baffle 808 and the lower guide baffle 809 guide the opening. After reaching the sealing position, the sealing motor 801 is turned on, and the sealing screw 802 moves backward, pulling the sealing arm 803 to rotate around the middle. The sealing pressure plate 804 is pressed tightly on the pressure plate bottom plate 805. The dragon gun lifting cylinder 806 extends, moves the dragon gun 807 to the sealing position, turns on the dragon gun 807, and tightens the bag mouth with the dragon gun card. After that, the dragon gun 807 returns to its position, and the sealing assembly 8 returns to its position. The finished product conveying mechanism 7 sends the sealed bag out, and the packaging process is completed.

[0060] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
