[0002] The width of the roll film needs to be measured during the processing process to facilitate classification and storage, and also to facilitate partial splicing and stacking. The traditional way to measure the width of the roll film is to use a leather tape measure. The roll film is placed on the ground and the height is measured by manually holding the leather roll to get the width of the roll film.

[0003] The prior art also discloses a size side feeder for packaging bag roll film with patent number CN216645293U, which specifically includes a bracket and also includes: a first connecting plate, which is arranged at the front end of the bracket; a second connecting plate, which is arranged at the rear end of the bracket; the bracket is provided with an input roller, a measuring roller, and an output roller from left to right; a first film pressing device, which is arranged below between the input roller and the measuring roller; the rotating shaft of the first pointer in the middle of the first film pressing force gauge is fixedly connected to the first rotating shaft; a second film pressing device, which is arranged below between the input roller and the measuring roller; the rotating shaft of the second pointer in the middle of the second film pressing force gauge is fixedly connected to the second rotating shaft. However, since the patent uses a fixed frame, it is not possible to effectively measure the width of a longer roll film, and the scope of use is not wide enough, and the application scenarios are not diverse enough.

[0004] Therefore, we propose a film roll width measuring device to solve this problem. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example:

The visual device 72 is used to monitor whether the roll film 8 to be inspected transmitted on the conveyor belt 3 reaches the inspection area. It should be noted that the visual device 92 is a conventional device in the prior art, that is, the width of the roll film 8 can be detected after it reaches the designated place through the effect of visual sensing.

[0026] The left and right sides of the machine 1 are both provided with movable infrared measuring components 9 in the direction of the conveyor belt 3, as shown in Figure 2, wherein the movable form of the infrared measurement component 9 is achieved by setting the supporting bottom 92 on the slide 94, the slide 94 is sleeved on the slide rail, the rear end of the slide 94 is connected to the piston rod of the cylinder 95, and is pushed forward by the cylinder 95. At the same time, in order to facilitate the installation of the cylinder 95, the cylinder 95 is installed on the bracket, and the bracket is fixedly installed at the rear end of the machine 1; the infrared measurement component 9 includes a measuring head 91 and a supporting bottom 92, one end of the measuring head 91 and the supporting bottom 92 are movably connected and the angle is adjustable, and the measuring head 91 is provided with an infrared measurement probe 93 in the direction toward the center, through The width of the roll film 8 to be detected is measured by measuring the distance between the two infrared measuring probes 93 and the head and tail ends of the roll film 8 to be detected. The infrared measuring component 9 is electrically connected to the controller 4. The measuring head 91 and the other end of the supporting bottom 92 are snap-fitted. Specifically, in order to effectively store and cover the measuring head 91 and the supporting bottom 92 when not in use, the measuring head 91 and the other end of the supporting bottom 92 are respectively provided with magnetic buckles 96 that attract each other. When covered, the two magnetic buckles 96 fit each other and are locked by magnetic attraction. Of course, the measuring head 91 and the supporting bottom 92 can also be combined into one by snapping.

[0028] When the utility model is in use, a roll of film to be detected is placed on a conveyor belt for transmission. When the roll of film to be detected is delivered to the position of the visual device, the visual device senses that the roll of film to be detected has reached the monitoring area, that is, the conveyor belt is suspended, and the cylinder is driven by the controller to drive the piston rod forward, thereby pushing the infrared measuring component toward the conveyor belt. At this time, the measuring head and the supporting bottom are at an acute angle (working state), and the distance between the head and the tail of the roll of film to be detected is measured by using an infrared measuring probe arranged toward the center. Using a set algorithm, the distance between the two infrared measuring probes minus the distance between the first infrared measuring probe and the roll of film to be detected and then minus the distance between the second infrared measuring probe and the roll of film to be detected is obtained to obtain the width of the roll of film to be detected, which is then classified and filed and placed in partitions.
