Abstract
Description
Technical Field
[0001] This utility model belongs to the field of packaging equipment technology, and specifically relates to a packaging bag film conveying device. Background Technology
[0002] Packaging film is a raw material used for packaging bags and is widely used in the packaging of various products. In the product packaging process, a roll of film printed with multiple packaging bag patterns evenly spaced along its length is usually placed on a film roll unwinding device to unwind the film roll; then, a conveying device delivers packaging bag film of a preset length one by one to a film slitting device for cutting to form packaging bags.
[0003] However, in the existing technology, due to limitations in the printing process, the patterns printed on the packaging film are not perfectly evenly spaced. If the conveying device still feeds the packaging film according to the preset length, it cannot ensure that each pattern is not in the predetermined position on the packaging bag, and there may even be cases where an incomplete pattern appears on a single packaging bag. Utility Model Content
[0004] To address the shortcomings of the existing technology, the purpose of this utility model is to provide a packaging bag film conveying device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] This utility model provides a packaging bag film conveying device, disposed between a film roll unloading device and a film slitting device, for conveying the packaging bag film released by the film roll unloading device to the film slitting device. The packaging bag film is printed with a plurality of packaging bag patterns spaced apart along the length direction of the packaging bag film. It features: a regulating section, corresponding to the output end of the film roll unloading device, having a regulating groove extending along the conveying direction of the packaging bag film and matching the width of the packaging bag film; and a conveying section, including a belt conveyor unit with its two ends corresponding to the output end of the regulating section and the input end of the film slitting device, respectively, and a drive mechanism. The system includes a conveyor drive unit that drives the belt conveyor unit; and a control unit, comprising a camera and a controller electrically connected to the camera and the conveyor drive unit respectively. The camera is positioned above the regulating groove and is used to acquire images of the packaging bag pattern on the packaging bag film passing through the regulating groove in real time as the current pattern image. The controller is used to compare the current pattern image with a pre-stored preset pattern image to obtain the actual distance value between two adjacent packaging bag patterns on the packaging bag film, and to control the conveyor drive unit to work according to the actual distance value so that the belt conveyor unit conveys the packaging bag film of the corresponding length.
[0007] The packaging bag film conveying device provided by this utility model may also have the following feature: the regulating part includes a positioning platform and a regulating film tool disposed on the positioning platform, and the upper surface of the regulating film tool is formed with a regulating groove.
[0008] The packaging bag film conveying device provided by this utility model may also have the following features: the camera is set on the positioning platform through a guide rail slider mechanism. The guide rail slider mechanism includes a linear guide rail, a slider and a mounting arm. The linear guide rail is fixedly set on the positioning platform and arranged parallel to the groove. The slider is slidably set on the linear guide rail. The mounting arm is set perpendicular to the linear guide rail, with one end fixedly connected to the slider, and the camera is mounted on the other end of the mounting arm.
[0009] The packaging bag film conveying device provided by this utility model may also have the following feature: the belt conveyor unit is arranged at an angle.
[0010] The packaging bag film conveying device provided by this utility model may also have the following feature: the camera is an IV-HG300CA type sensor probe.
[0011] The packaging bag film conveying device provided by this utility model may also have the following feature: wherein the controller is an IV-HG10 type image recognition sensor controller.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] (1) The camera captures images of the packaging bag pattern on the packaging bag film passing through the groove in real time as the current pattern image. The controller compares the current pattern image with the preset pattern image stored in advance to obtain the actual distance value between two adjacent packaging bag patterns on the packaging bag film. Based on the actual distance value, the controller controls the conveyor drive to work so that the belt conveyor unit conveys the corresponding length of packaging bag film. This realizes the function of accurately controlling the movement position of the packaging bag film according to the actual position of the pattern on the packaging bag film.
[0014] (2) By setting a regulating groove that extends along the conveying direction of the packaging film and matches the width of the packaging film, the packaging film can be limited and regulated in the width direction, ensuring the stability and reliability of the movement direction of the packaging film.
