Description

Technical Field

[0001] The utility model relates to the technical field of leakage detection of infusion bags, in particular to a pressure leakage detection device for a large infusion bag. Background Art

[0002] After filling, a large infusion bag needs to be checked by a dedicated person to see if there is any leakage. The actual leakage rate of the product coming out of the filling machine is less than 5‰. The utilization rate of this leak-picking person is extremely low and cannot be omitted. In addition, the existing detection device still requires manual observation, which does not save labor and there are still cases of leak-picking errors.

[0003] Chinese patent: a liquid small packaging bag leakage detection device {publication (announcement) number: CN205719422U}, the utility model discloses a liquid small packaging bag leakage detection device, including a conveyor, a bracket arranged on the frame of the conveyor, and a pressure roller is arranged on the bracket. The pressure roller is located above the conveyor and presses on the packaging bag passing through the conveyor. The utility model has a simple structure and is easy to operate, which improves the efficiency of leakage detection and protects workers from being splashed by liquid medicine;

[0004] The manual mentions that "when in use, the packaging bag passes through the conveyor and the pressure roller presses on the packaging bag. The worker only needs to observe whether there is any leakage. The height of the pressure roller can be adjusted by rotating the height adjustment lever to adapt to the leak detection operation of different types of packaging bags (see manual

[0006] )" and "the utility model has a simple structure and is easy to operate, which improves the efficiency of leak detection and protects workers from being splashed by liquid medicine (see manual

[0007] )". It can be seen that the technical solution disclosed in a leak detection device for small liquid packaging bags still requires manual observation and does not save labor. Moreover, the method of manual observation of leakage will also lead to a decrease in the pass rate.

[0005] Chinese patent for a leakage detection device for liquid packaging bags {Publication (Announcement) No.: CN218180210U}, the utility model discloses a leakage detection device for liquid packaging bags, which relates to a leakage detection device, and proposes this solution to solve the problem that leakage detection in the prior art relies on manual labor. It includes a gantry spanning both sides of the conveyor belt, and a roller mechanism hinged to the gantry; a rotating shaft is provided in the middle of the top of the gantry, and the rotating shaft is used to be hinged to the roller mechanism; the roller mechanism is used to press the packaging bag passing under it. The advantage is that it is only necessary to observe whether liquid appears on the conveyor belt after the packaging bag passes under the roller to determine whether the packaging bag is leaking. No manual sampling is required, and the detection rate is 100%. The detection process will not affect the normal operation of the production line, and will not affect the overall work efficiency while maintaining a high accuracy rate. It is especially suitable for use in miniaturized production lines;

[0006] The manual mentions that "it is only necessary to observe whether liquid appears on the conveyor belt after the packaging bag passes under the pressure roller to determine whether the packaging bag is leaking." This shows that the technical solution disclosed in a leakage detection device for a liquid packaging bag still requires manual observation to determine whether there is leakage. The disadvantages of this are also the inevitable use of manual labor and low accuracy.

[0007] In order to solve the above problems, the present application proposes a large infusion bag pressure leak detection device. Utility Model Content

[0025] Support columns A8 are fixedly installed on both sides of the conveyor belt device 10, support columns B14 are fixedly installed between the conveyor belt device 10 and the bracket 9, and a partition plate 7 is also fixedly installed on the conveyor belt device 10. Two guide shafts 3 and screw nuts B15 are symmetrically arranged with the ball screw 1 as the symmetry axis.

[0026] In this embodiment, the support plate 5 can be moved up and down on the bracket 9 by the action of the adjusting handle 2 and the ball screw 1. The connection between the fixing nut 21 and the support plate 5 is bolted, and the fixing nut 21 is locked on the support plate 5. Two adjusting handles 2 are installed on the bracket 9 through bolt connection. Any one of the two adjusting handles 2 is connected to the ball screw. The connection between the screw nut A12 sleeved on the ball screw 1 and the protective cover A22 is bolted.

After the electric roller 20 rolls over the infusion bag 18, the pressure detection module 17 detects the pressure of the infusion bag 18 and then transmits the signal to the control module through the feedback of the weighing module 16. The qualified ones continue to go to the next station for packaging, and the unqualified ones are transported to the unqualified station for testing.

[0027] Specifically, only a gap is provided between the conveyor belt device 10 and the electric drum 20 for the infusion bag 18 to pass through when being detected.

[0028] In this embodiment, the gap for detecting the passage of the infusion bag 18 can be adjusted by rotating the adjustment handle 2 to drive the ball screw to rotate, thereby adjusting the upper and lower distances of the support plate 5 .

[0029] Specifically, the lower end surface of the partition plate 4 is also fixedly mounted on the upper end surface of the support plate 5 , and the upper end surface of the partition plate 4 is fixedly mounted on the bracket 9 .

[0030] In this embodiment, the support plate 5 and the partition plate 4 are connected by welding, and the partition plate 4 and the bracket 9 are connected by welding.

[0031] The working principle and use process of the utility model are as follows: the personnel adjust the height of the electric roller 20 by turning the adjustment handle 2 to adapt to the infusion bags 18 products of different specifications (the roller adjustment height is ±100); after being adjusted to the right position, the electric roller 20 is powered on and has the same speed as the conveyor belt device 10 below, and the product is squeezed by the conveyor belt device 10 and the electric roller 20. The weighing module 16 above the electric roller 20 displays the pressure value according to the thickness of the product, and compares it with the set value. If it is ≥ the set value, it is a qualified product, and if it is < the set value, it is a failed product (the set value is 0, and the error is ±3 kg); it is automatically rejected at the next station and manually processed.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
