Description

Technical Field

[0001] This utility model relates to the field of testing machines, and in particular to a flexible packaging testing machine. Background Technology

[0002] Flexible packaging is a type of packaging that can flexibly change shape after being filled or removed from its contents. It is widely manufactured using paper, aluminum foil, fiber materials, plastic films, and composites of these materials, and comes in various forms, including but not limited to bags, boxes, sleeves, and covers. In recent years, the flexible packaging industry has experienced rapid growth, and its applications have become increasingly widespread. In the food industry, especially for beverages and crispy foods, flexible packaging is often used for sealing to ensure product freshness and safety. However, if the seal is not tight, flexible packaging may leak air, affecting the product's shelf life; at the same time, if the seal's pressure resistance is insufficient, flexible packaging is easily damaged under external forces. To ensure the quality of flexible packaging products, manufacturers typically first visually inspect the packaging's appearance for integrity, and then conduct random sampling inspections of some products to further verify their quality and sealing performance.

[0003] Currently, after production, flexible packaging requires random sampling for airtightness testing. Manual visual inspection mostly involves checking the product's appearance for any defects, easily identifying unsealed or poorly sealed packaging. However, for packaging with inadequate seals or insufficient pressure resistance, visual inspection is insufficient to identify these substandard packages. Some methods, such as placing the packaging in a sealed space for leak testing, are time-consuming and inefficient for large-scale testing.

[0004] To address the aforementioned issues, this application proposes a flexible packaging inspection machine. Utility Model Content

[0005] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a flexible packaging inspection machine. This utility model incorporates a squeezing mechanism to facilitate inspection and increase the inspection rate.

[0006] (II) Technical Solution To solve the above problems, this utility model provides a flexible packaging inspection machine, including a box body with an upward opening, a mounting frame fixedly installed on one side of the box body, and a driving component fixedly installed on the mounting frame; A drain outlet is provided on one side of the box body; The driving rod of the driving component is connected to a squeezing mechanism. When the squeezing mechanism is driven out by the driving component, the liquid inside the box is discharged through the drain port.

[0007] Preferably, the extrusion mechanism includes a mesh plate, a baffle strip, and a baffle plate. The mesh plate is slidably sleeved inside the box body. The baffle strip is placed on the mesh plate. The top of the baffle plate is fixedly connected to the baffle strip. The bottom of the baffle plate slides through the mesh plate. An opening is provided at the bottom of the baffle plate. A scraper is fixedly installed at the bottom of the baffle plate.

[0008] Preferably, the scraper is inclined.

[0009] Preferably, the driving component is a pneumatic cylinder or a hydraulic cylinder.

[0010] Preferably, a rubber frame is fixedly fitted around the outer periphery of the scraper.

[0011] Preferably, the box is a transparent box.

[0012] The above-mentioned technical solution of this utility model has the following beneficial technical effects: The packaging bag is filled with colored gas and placed inside the box, at the top of the baffle. The drive unit moves the screen plate downwards, allowing water to enter the box through the screen plate. The drive unit continues to move the screen plate downwards to compress the packaging bag. In case of leakage, the colored gas inside the packaging bag is ejected, making it easier to observe for leaks and increasing the detection rate. After detection, the drive unit moves back, moving the screen plate out of the box. As the screen plate moves out of the box, it also moves the baffle upwards, causing the baffle and scraper to move upwards as well. This positions the bottom opening of the baffle at the drain port, allowing the water inside the box to be drained, thus replacing the water inside the box. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0018] like Figure 1-3 As shown, the present invention proposes a flexible packaging inspection machine, which includes a box body 1 with an upward opening, a mounting frame 2 fixedly installed on one side of the box body 1, and a driving component 3 fixedly installed on the mounting frame 2. A drain port 101 is provided on one side of the box body 1; The driving rod of the driving component 3 is connected to the extrusion mechanism 4. When the extrusion mechanism 4 is driven out by the driving component 3, the liquid inside the box 1 is discharged through the drain port 101.

[0019] In an optional embodiment, the extrusion mechanism 4 includes a mesh plate 41, a baffle 42, and a baffle 43. The mesh plate 41 is slidably sleeved inside the box body 1. The baffle 42 is placed on the mesh plate 41. The top of the baffle 43 is fixedly connected to the baffle 42. The bottom of the baffle 43 slides through the mesh plate 41. An opening is provided at the bottom of the baffle 43. A scraper 44 is fixedly installed at the bottom of the baffle 43.

[0020] It should be noted that the bottom wall of box 1 is inclined.

[0021] In an optional embodiment, the scraper 44 is angled.

[0022] It should be noted that the inclined design of scraper 44 facilitates the diversion of water.

[0023] Specifically, the driving component 3 is a pneumatic cylinder or a hydraulic cylinder.

[0024] In an optional embodiment, the outer periphery of the scraper 44 is fixedly fitted with a rubber frame.

[0025] It should be noted that, under the action of the rubber frame, when the scraper 44 moves upward, it scrapes the inner wall of the box 1.

[0026] In an optional embodiment, the box 1 is a transparent box.

[0027] It should be noted that the function of box 1 is to facilitate the observation of the internal situation of box 1.

[0028] In this invention, a colored gas is filled inside a packaging bag, which is then placed inside the box 1 and positioned on top of a baffle 43. A drive unit 3 moves a mesh plate 41 downwards, allowing water to enter the box 1 through the mesh plate 41. The drive unit 3 continues to move the mesh plate 41 downwards to compress the packaging bag. In case of leakage, the colored gas inside the packaging bag is ejected, facilitating the observation of any leaks and increasing the detection rate. After detection, the drive unit 3 moves back, moving the mesh plate 41 out of the box 1. As the mesh plate 41 moves out of the box 1, it also moves the baffle 42 upwards, causing the baffle 43 and scraper 44 to move upwards as well. This positions the bottom opening of the baffle 43 at the drain outlet 101, allowing the water inside the box 1 to be drained, thus replacing the water inside the box 1.

[0029] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
