Technical Field

[0001] The utility model relates to the technical field of packaging bag conveying, in particular to an anti-accumulation mechanism for packaging bag conveying. Background Art

[0002] On the market, most of the jujubes are packaged in plastic bags. Plastic bag packaging can prevent the jujubes from absorbing moisture, ensuring product quality, extending the shelf life, and at the same time improving the appearance of the product and making it convenient for consumers to use. During packaging, multiple plastic bags are intermittently conveyed by a bag conveyor, and the bag conveyor is provided with a single bag separation mechanism to prevent the accumulation of packaging bags, so that a single plastic bag can pass through. However, in actual use, packaging bags often accumulate after passing over the single bag separation mechanism during transportation. For this reason, an anti-accumulation mechanism that can prevent the accumulation of packaging bags has been developed and applied to the packaging bag conveyor to ensure the continuous transportation of packaging bags.

[0012] (3) Beneficial effects

[0013] Compared with the prior art, the present invention provides an anti-stacking mechanism for feeding packaging bags, which has the following beneficial effects:

[0014] The anti-stacking mechanism for feeding packaging bags is configured with a transverse shaft, a movable sleeve and an arc plate. When the packaging bag at the bottom passes through the bottom of the arc plate, the movable sleeve and the arc plate as a whole are shaken up and down. Therefore, in the process of continuously conveying a single bag, the movable sleeve and the arc plate as a whole are in a state of continuous up and down shaking on the transverse shaft. When the second packaging bag at the bottom is in the conveying process, the arc plate can rotate, thereby preventing the second packaging bag from being conveyed, thereby ensuring the continuity of the passage of the single bag and avoiding accumulation. The anti-stacking mechanism for feeding packaging bags is convenient for allowing only a single packaging bag to pass, and is convenient for blocking the packaging bags above the bottom packaging bag, thereby ensuring the continuity of the passage of the single packaging bag and avoiding accumulation during the packaging bag conveying process.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example:

[0022] See also Figure 1-4 A packaging bag feeding anti-accumulation mechanism includes a positioning frame, a U-shaped frame 1 is provided at the bottom of the positioning frame, a horizontal shaft 2 is provided at the bottom of the U-shaped frame 1, a movable sleeve 3 is movably sleeved on the horizontal shaft 2, and an arc plate 4 is fixedly installed at the bottom of the movable sleeve 3.

[0023] Specifically, concave rings 5 are provided on both sides of the cross shaft 2, and rotating grooves 6 that rotate and slide with the concave rings 5 are provided on the bottom of both sides of the U-shaped frame 1. The top of the rotating groove 6 is connected to a through groove 7 for the cross shaft 2 to pass through. Through the arrangement of the concave ring 5, the rotating groove 6 and the through groove 7, the cross shaft 2 can be conveniently lifted up to the through groove 7, and the cross shaft 2 can be pulled out from the two through grooves 7, so that the movable sleeve 3 and the arc plate 4 can be disassembled. During assembly, the movable sleeve 3 can be placed in the position between the two through grooves 7, and then the cross shaft 2 can be passed through the two through grooves 7 to support the movable sleeve 3, and then the concave ring 5 can be pushed down to the rotating groove 6, so that the cross shaft 2 can be clamped in the position between the two rotating grooves 6, which is convenient for disassembly and maintenance operations.

[0024] Specifically, it also includes an adjustment structure for adjusting the overall up and down front and back positions of the cross shaft 2, the movable sleeve 3 and the curved plate 4. The adjustment mechanism includes a front and back adjustment mechanism and an up and down adjustment mechanism. The positioning frame slides forward and backward with a horizontal slider 11. The front and back adjustment mechanism is used to adjust the front and back positions of the horizontal slider 11 on the positioning frame. The up and down adjustment mechanism adjusts the up and down spacing between the U-shaped frame 1 and the horizontal slider 11. The adjustment structure can facilitate the adjustment of the overall up and down front and back positions of the cross shaft 2, the movable sleeve 3 and the curved plate 4, thereby improving the installation flexibility. The front and back positions can be adjusted through the front and back adjustment mechanism, and the up and down height positions can be adjusted through the up and down adjustment mechanism.

[0025] Specifically, the front and rear adjustment mechanism includes a front and rear adjustment screw 14 rotatably connected to the top of the positioning frame. The front and rear adjustment screw 14 is threadedly connected to the horizontal slider 11. By rotating the front and rear adjustment screw 14 clockwise or counterclockwise, the horizontal slider 11 can be driven to rotate clockwise or counterclockwise, thereby driving the horizontal slider 11 to move forward and backward.

[0026] Specifically, the up and down adjustment mechanism includes a lifting and adjusting screw 12 with a vertical thread passing through the horizontal slider 11. The bottom end of the lifting and adjusting screw 12 is rotatably connected to the top of the U-shaped frame 1. The top of the U-shaped frame 1 is fixedly installed with a lifting guide rod 13 that vertically slides with the horizontal slider 11. By rotating the lifting and adjusting screw 12 clockwise or counterclockwise and under the guidance of the lifting guide rod 13, the U-shaped frame 1 is lifted and lowered. Furthermore, the top of the lifting and adjusting screw 12 and the end of the front and rear adjusting screw 14 are fixedly installed with an adjusting button 15, and the rotation of the lifting and adjusting screw 12 and the front and rear adjusting screw 14 can be conveniently adjusted by the adjusting button 15.

[0027] Specifically, the positioning frame includes a top frame 8 with support legs 9 fixedly installed at the bottom of both left and right sides, and a mounting plate 10 fixedly installed on the top frame 8 on both left and right sides, which facilitates the installation of the positioning frame through the mounting plate 10.

[0028] When in use, the positioning frame is fixed to the rear side of the single bag separation mechanism on the conveying channel of the packaging bag conveyor. When the packaging bag passes under the curved plate 4, the movable sleeve 3 and the curved plate 4 are in an up and down bumping state as a whole each time the packaging bag passes continuously. Each time it rises, a packaging bag passes through. After falling, it can prevent the second packaging bag on the rear side from passing through together with the packaging bag at the bottom.
