Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag sealing detection, in particular to a packaging bag sealing quality detection device. Background Art

[0002] Sealing packaging with packaging bags is a very common packaging method. Before the sealed items are officially put into use, the sealing quality of the packaging bag seal needs to be tested to prevent accidents such as packaging leakage and defective products.

[0003] A packaging bag sealing quality inspection device is disclosed in the patent document with publication number CN220084249U, which includes a base, a detection platform is fixedly connected to the upper surface of the base, a detection frame is fixedly connected to the back of the base, an infrared rangefinder is arranged on the detection frame, a reflector matching the infrared rangefinder is arranged on the upper surface of the base, the output end of the infrared rangefinder is directly irradiated to the reflector, and a fixed component is arranged on the upper surface of the base. In the process of implementing the technical solution, the inventor found that there are at least the following problems in the prior art:

[0004] After the packaging bag is sealed, the inside is filled with air, so it is relatively soft and has a smooth surface. The above-mentioned device uses two fixed baffles to rigidly clamp the packaging bag, and the fixing effect is weak and the packaging bag is easy to burst. At the same time, the motor drives the lead screw to drive the connecting plate to fit with the packaging bag. Even if the packaging bag leaks, the connecting plate will remain stationary under the limit of the lead screw, resulting in difficulty in accurately detecting the sealing of the packaging bag by observing the change in the distance between the infrared rangefinder and the reflective plate, and the use effect is not good.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Please refer to Figure 1-Figure 4 , a packaging bag sealing quality detection device comprises a fixing plate 1.

[0022] In the specific implementation process, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fixed seat 2 is fixedly connected to the top of the fixed plate 1, and a holding component 3 for fixing the packaging bag is arranged above the fixed seat 2. Moving plates 4 are slidably arranged on both sides of the fixed seat 2, a pointer 5 is arranged on the top of the moving plate 4, and scale lines used in conjunction with the pointer 5 are arranged on both sides of the fixed seat 2. Positioning rods 6 are fixedly connected to both sides of the moving plate 4, and moving blocks 7 are slidably arranged on both sides of the fixed seat 2. A positioning ring 8 is fixedly connected to one side of the moving block 7, and the positioning ring 8 is sleeved on the positioning rod 6. An arc-shaped top plate 9 is fixedly connected to the top of the moving plate 4, and a plurality of first springs 10 are fixedly connected to the bottom of the arc-shaped top plate 9.

[0023] The pressing assembly 3 includes a fixed block 31 arranged on both sides of the fixed seat 2, a moving rod 32 is inserted in the fixed block 31, the bottom of the moving rod 32 is fixedly connected to a limiting plate 33, the top of the limiting plate 33 is fixedly connected to a second spring 34, the second spring 34 is sleeved on the moving rod 32, and the top of the moving rod 32 is fixedly connected to an arc-shaped pressing plate 35.

[0024] The second spring 34 releases the stored energy to make the arc pressure plate 35 flexibly press the packaging bag, which not only has a good fixing effect but also is not easy to cause damage to the packaging bag. Then, the two moving blocks 7 are moved to separate the positioning ring 8 from the positioning rod 6, and the positioning of the moving plate 4 is released. The arc top plate 9 moves upward under the elastic force of the first spring 10, squeezes the packaging bag on the top of the fixed seat 2, and detects the sealing of the packaging bag. If the packaging bag leaks, the arc top plate 9 will continue to move upward. At this time, the position of the pointer 5 at the top of the moving plate 4 and the scale line can be used to observe the degree of leakage of the packaging bag.

[0025] Through slots 11 are formed on both sides of the fixing seat 2 , and the outer side of the movable plate 4 is slidably matched with the inner wall of the through slot 11 .

[0026] Slide grooves 12 are provided on both sides of the fixing seat 2 . The number of the slide grooves 12 is set to two, and the outer side of the moving block 7 is slidably matched with the inner wall of the slide groove 12 .

[0027] A moving groove 13 for use with the arc-shaped top plate 9 is provided inside the fixing seat 2 , and a pull rod 14 is fixedly connected to the top of the arc-shaped pressing plate 35 .

[0028] The four corners of the bottom of the fixed plate 1 are fixedly connected with fixed legs 15 , the bottom of the fixed legs 15 is fixedly connected with a bottom plate 16 , and the bottom of the bottom plate 16 is provided with moving wheels 17 .

[0029] It should be noted that: when the arc-shaped top plate 9 moves, the movable plate 4 slides in the through groove 11, guiding and limiting the movable plate 4, thereby improving the stability of the movable plate 4 when moving; the movable block 7 slides in the slide groove 12, so that the positioning ring 8 is sleeved on the positioning rod 6 to position the movable plate 4; the movable groove 13 makes way for the arc-shaped top plate 9, so that the arc-shaped top plate 9 can move freely in the fixed seat 2; the pull rod 14 is used to facilitate pulling the arc-shaped pressure plate 35; the fixed legs 15 and the bottom plate 16 support and fix the fixed plate 1; the moving wheels 17 facilitate movement of the device, thereby improving convenience.

[0030] The working principle of the packaging bag sealing quality detection device provided by the utility model is as follows:

[0031] When in use, first pull the arc pressure plate 35 upward to drive the moving rod 32 to move upward, and the moving rod 32 slides in the fixing block 31 and drives the limiting plate 33 to move upward. At this time, the limiting plate 33 compresses the second spring 34 to store energy, and then the sealed packaging bag is placed on the top of the fixing seat 2. Then, the arc pressure plate 35 is released, and the second spring 34 releases the stored energy to make the arc pressure plate 35 flexibly press the packaging bag, which not only has a good fixing effect but also is not easy to cause damage to the packaging bag. Then, the two moving blocks 7 are moved to separate the positioning ring 8 from the positioning rod 6, and the positioning of the moving plate 4 is released. The arc top plate 9 moves upward under the elastic force of the first spring 10, squeezes the packaging bag on the top of the fixing seat 2, and detects the sealing of the packaging bag. If the packaging bag leaks, the arc top plate 9 will continue to move upward. At this time, the position of the pointer 5 on the top of the moving plate 4 and the scale line can be used to observe the degree of leakage of the packaging bag, and the sealing quality of the sealing part of the packaging bag can be detected.

[0032] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
