AI Technical Summary
The existing oral liquid strip bag opening method requires the strip bag to be suspended, resulting in intermittent traction, which can easily cause wrinkles and uneven traction problems.
A device is adopted that includes a reel and a symmetrically distributed air suction drum. The air suction drum has a hollow cylinder and a negative pressure air source, and a triangular suction hole is distributed on the cylinder for continuous traction and opening the strip bag.
The stable opening of the bag in the continuous traction state is achieved, reducing wrinkles and uneven traction conditions, and improving the opening range.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of food processing equipment and relates to a strip bag opening device on an oral liquid strip bag packaging machine. Background Art
[0002] Oral liquid strip bag packaging is a packaging method in which oral liquid is poured into a strip bag. The strip bag has a hollow structure. After being opened, it is sealed twice to form a closed cavity. After the first seal, the oral liquid is poured in and then sealed a second time.
[0003] The strip is unloaded in the form of a coil and needs to be stretched before filling. At present, the stretching method is: two suction cups set along the flat direction suck and pull outward, and then blow it toward the bag mouth. This method requires the coil to be paused, that is, the strip bag coil is in an intermittent traction state, which is easy to cause wrinkles in the strip bag and uneven traction. Utility Model Content
[0004] The purpose of the utility model is to provide a strip bag opening device on an oral liquid strip bag packaging machine in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to open the strip bag under continuous traction.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a strip bag expansion device on an oral liquid strip bag packaging machine, characterized in that it includes a reel and two air suction rollers, the strip bag is rolled up by the reel, and the two air suction rollers are symmetrically distributed on both sides of the strip bag pull-out end, the air suction roller includes an outer protective cover and a hollow cylinder rotatably connected to the outer protective cover, the hollow cylinder is close to the flat side of the strip bag, the inner cavity of the hollow cylinder is connected to a negative pressure air source, and a plurality of groups of suction holes are arranged on the circumferential surface of the hollow cylinder.
[0006] Furthermore, each of the air intake holes in a single group of air intake holes is in a triangular shape. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 It is a structural schematic diagram of the present propping device.
[0008] Figure 2 It is a structural diagram of the wind system drum.
[0009] In the figure, 1, reel; 2, air suction roller; 3, hollow cylinder; 4, air suction hole; 5, outer protective cover. DETAILED DESCRIPTION
[0010] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0011] like Figure 1 and Figure 2The strip bag opening device on the oral liquid strip bag packaging machine shown is characterized in that it includes a reel 1 and two air suction rollers 2, the strip bag is rolled up by the reel 1, the two air suction rollers 2 are symmetrically distributed on both sides of the strip bag pull-out end, the air suction roller 2 includes an outer shield 5 and a hollow cylinder 3 rotatably connected in the outer shield 5, the hollow cylinder 3 is close to the flat side of the strip bag, the inner cavity of the hollow cylinder 3 is connected to the negative pressure gas source, and a plurality of groups of suction holes 4 are arranged on the circumference of the hollow cylinder 3, and each suction hole 4 in a single group of suction holes 4 is triangular in shape. The area where the suction holes 4 with a larger distribution area are located contacts the flat strip bag, and as the hollow cylinder separates from the strip bag, the number of suction holes 4 gradually decreases, and the suction position tends to the middle of the strip bag, so that the strip bag can be pulled open, and the opening amplitude is larger.
[0012] The two air suction rollers 2 rotate synchronously, that is, a gear is arranged at each axis, and the two gears mesh with each other. The function of the external call cover is to only allow the hollow cylinder 3 and the part close to the bag to generate negative pressure airflow.
[0013] The specific embodiments described herein are merely examples of the spirit of the present invention. A person skilled in the art of the present invention may make various modifications or additions to the specific embodiments described or replace them in a similar manner, but this will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
