Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag production, in particular to a winding device for disconnected rolled plastic bags. Background Art

[0002] People often use disposable plastic bags, disposable fresh-keeping bags and other disposable plastic bags in their daily lives. Common disposable plastic bags include vest bags, drawstring bags and the like. Disposable plastic bags are usually stacked or rolled. Stacked plastic bags are multiple disposable plastic bags placed in a stack; rolled plastic bags are multiple interconnected point-break plastic bags rolled into a roll. A point-break line is set between two adjacent plastic bags of the point-break plastic bag. The point-break line refers to the puncture point connecting the two plastic bags and looks like a dotted line. When using a rolled plastic bag, consumers need to tear off the next plastic bag along the point-break line. If the force is uneven when tearing, the plastic bag is easily torn. Therefore, the disconnected rolled plastic bag came into being.

[0003] A disconnected roll plastic bag refers to a plurality of independent plastic bags partially overlapped and then rolled into a roll. Since each plastic bag is independent of each other, consumers do not need to tear it by hand when using it. When manufacturers produce disconnected roll plastic bags, they need to roll the disconnected and partially overlapped plastic bags into a tightly wound roll. Therefore, a winding device for disconnected roll plastic bags is urgently needed. Utility Model Content

[0035] The suction device 7 includes an air suction nozzle 71. The air suction nozzle 71 is fixedly provided at one end of the sealing main pipe 41 located on the outside of the body 1.

The inner cavity of the sealing main pipe 41 and the inner cavity of the coiled pipe 43 are connected through an air suction hose 72. The air suction hose 72 is provided with an air suction solenoid valve 73. A plurality of suction holes 44 are opened on the side wall of the coiled pipe 43 located on the inside of the body 1.

[0036] In this embodiment, the suction nozzle 71 is connected to an external suction pump. When the suction pump is working, the suction solenoid valve 73 corresponding to the material coiling tube 43 matched with the regulating device 5 is opened, the sealing main pipe 41 and the material coiling tube 43 are in a negative pressure state, and when the air flow enters from the suction hole 44 opened on the side wall of the rotating material coiling tube 43, the plastic bag on the feeding belt 23 is sucked and rolled up, and then the suction solenoid valve 73 is closed.

[0037] The pushing device 8 includes a pushing cylinder 81 fixedly arranged on the outside of the machine body 1 .

[0039] When the utility model is working, the feeding drive motor 31 rotates and drives the feeding drive active synchronous wheel 32 to rotate, the feeding drive active synchronous wheel 32 drives the feeding active roller 21 to rotate through the feeding drive passive synchronous wheel 33 and the feeding drive passive synchronous wheel 33, the feeding active roller 21 drives the upper pressure roller 24 in contact with it to rotate in the opposite direction, and the partially overlapping and independent plastic bags between the feeding belt 23 and the upper pressure roller 24 are transmitted backwards through the friction force of the feeding belt 23 and the pressure wheel belt 27.

The adjusting synchronous belt 65 contacts and cooperates with one of the adjusting synchronous wheels 55, and at this time, the winding tube 43 connected to the adjusting synchronous wheel 55 rotates and is located above the feeding belt 23.

[0041] The suction pump works, the suction solenoid valve 73 corresponding to the coiling tube 43 opens, the sealing main pipe 41 and the coiling tube 43 are in a negative pressure state, and the airflow enters from the suction hole 44 opened on the side wall of the rotating coiling tube 43. The output end of the regulating cylinder 68 contracts, and the regulating fork 69 drives the regulating synchronous belt 65 and the regulating driven synchronous wheel 64 to rotate with the regulating main shaft 62 as the axis through the regulating plate 66. The regulating synchronous wheel 55 and the coiling tube 43 matched therewith move downward along the regulating long groove 51 under the cooperation of the slide rail 52 and the slide seat 53. The coiling tube 43 falls on the plastic bag on the feeding belt 23 and rotates by the friction force of the feeding belt 23. The airflow of the suction hole 44 sucks the plastic bag on the feeding belt 23, and the rotating coiling tube 43 starts to roll the plastic bag. At this time, the output end of the regulating cylinder 68 continues to contract, and the regulating synchronous belt 65 is no longer in contact with the regulating synchronous wheel 55.

[0042] like Figure 2 and Figure 3As shown, after a certain length of plastic bags are rolled onto the reel tube 43, the reel motor 45 drives the sealing main tube 41, the reel turntable 42 and the four reel tubes 43 to rotate 90° counterclockwise through the active synchronous wheel 46, the reel synchronous belt 48 and the reel passive synchronous wheel 47, and the reel tube 43 moves to the position of the reel tube 43 on its right side, and rotates through the friction force of the feed belt 23, and at the same time, the plastic bags on the feed belt 23 are rolled; at the same time, the output end of the adjusting cylinder 68 is extended, and the adjusting fork 69 drives the adjusting synchronous belt 65 and the adjusting driven synchronous wheel 64 to rotate around the adjusting main shaft 62 through the adjusting plate 66, and after the other reel tube 43 rotates, the adjusting synchronous wheel 55 on the reel tube 43 falls on the adjusting synchronous belt 65.

[0043] When a fixed number of plastic bags are rolled on the reel tube 43, the corresponding air suction solenoid valve 73 of the other reel tube 43 is opened, the sealing main pipe 41 and the reel tube 43 are in a negative pressure state, and the air flow enters from the suction hole 44 opened on the side wall of the rotating reel tube 43. The output end of the regulating cylinder 68 contracts, and the regulating fork 69 drives the regulating synchronous belt 65 and the regulating driven synchronous wheel 64 to rotate with the regulating main shaft 62 as the axis through the regulating plate 66. The regulating synchronous wheel 55 and the reel tube 43 cooperate with it move downward along the regulating long groove 51 under the cooperation of the slide rail 52 and the slide seat 53. The reel tube 43 falls on the plastic bag on the feeding belt 23 and rotates by the friction force of the feeding belt 23. The air flow of the suction hole 44 sucks the plastic bag on the feeding belt 23, and the rotating reel tube 43 starts to roll the plastic bag. At this time, the output end of the regulating cylinder 68 continues to contract, and the regulating synchronous belt 65 is no longer in contact with the regulating synchronous wheel 55. When a certain length of plastic bags is rolled onto another roll tube 43, the roll motor 45 drives the sealing main tube 41, the roll turntable 42 and the four roll tubes 43 to rotate 90° counterclockwise through the active synchronous wheel 46, the roll synchronous belt 48 and the roll passive synchronous wheel 47, and the roll tube 43 moves to the position of the roll tube 43 on its right side, and rotates through the friction force of the feeding belt 23, and rolls the plastic bags on the feeding belt 23 at the same time. After the roll tube 43 with a fixed number of plastic bags is rolled, it rotates to the position where the arc-shaped push plate 82 is located, and the output end of the push cylinder 81 extends, and the arc-shaped push plate 82 pushes out the plastic bags rolled on the roll tube 43, so that it is separated from the roll tube 43.
