Drawstring insertion device for garbage bag with string

Abstract

The invention discloses a drawstring insertion device for a garbage bag with a string. The drawstring insertion device structurally comprises two cutting wheels, a sleeve cover, a lengthening threading needle, an anti-reverse back penetration device, a fixing block, a connecting rod and a rear connecting block. The sleeve cover is arranged on the left of the anti-reverse back penetration device byadopting a clearance fit. The lengthening threading needle is arranged in the middle of the left of the sleeve cover by adopting the clearance fit. The two cutting wheels are arranged on the same plane, and the two cutting wheels are installed at the front and back ends of the right of the sleeve cover correspondingly by adopting the clearance fit. By setting the anti-reverse back penetration device, when the anti-reverse back penetration device in the process of threading during using, the reverse of the needle penetrating through can be avoided on the halfway so that the needle can penetrate through the garbage bag successfully, and thus the success rate of string threading is high. A sleeve connecting moving device is arranged inside the anti-reverse back penetration device, after theneedle penetrates through the garbage bag during using, the needle can be quickly pulled back without driving the string to return, and the situation that the string falls off again is reduced.

Description

technical field [0001] The invention relates to a drawstring embedding device for a rope-through garbage bag, which belongs to the field of drawcord embedding devices. Background technique [0002] When the device is in use, the garbage bag that needs to be threaded can be penetrated, and after the penetration, it can be pulled out through the penetrated rope, thereby tightening the opening of the garbage bag, so that the garbage inside the garbage bag does not There will be falls. [0003] when prior art is in use; [0004] 1. When the device is threading the rope, the needle that is threading the rope is likely to think that there is a backlash inside the device, which will cause the needle to shrink, and the garbage bag that is threading the rope will fail to thread the rope. Rope success rate is low; [0005] 2. After the device is threaded successfully, the threaded needle needs to be recovered for the next threading. During the shrinking process, the rope that has b...

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a rope-threading garbage bag drawstring embedding device to solve the problem of using the prior art; when the device is threading the rope, the needle that is threading the rope is easy to feel There is a backlash inside the device, which causes the needle to shrink, and the garbage bag being threaded fails to be threaded, and the success rate of threading is low; Recycling, so as to carry out the next threading, in the process of shrinking, it is easy to cause the problem that the rope that has been threaded successfully will fall off again after the needle shrinks
