Description

Technical Field

[0001] This utility model relates to the field of plastic bag detection technology, and in particular to a plastic bag thickness uniformity detector. Background Technology

[0002] With the rapid development of the packaging industry, plastic bags, as a common packaging material, directly affect the protective effect of products and the user experience of consumers. Among them, the thickness uniformity of plastic bags is one of the important indicators for measuring their quality. Uneven thickness may lead to problems such as reduced packaging strength and poor sealing, which in turn affect the shelf life and safety of products. Therefore, it is necessary to use a thickness uniformity detection device to detect the thickness of plastic bags.

[0003] An existing thickness measuring instrument for plastic bag quality inspection (publication number: CN212721364U) has at least the following drawbacks: Although the above device uses a magnetic plate to squeeze and fix the plastic bag, and then uses a thickness measuring instrument to measure the thickness, relying solely on the magnetic plate for fixation makes it difficult to completely smooth out the wrinkles on the surface of the plastic bag, resulting in unevenness in the measurement area, which affects the accuracy of the thickness measurement. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plastic bag thickness uniformity testing instrument.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plastic bag thickness uniformity tester includes a box body. The bottom surface of the box body is provided with a thickness tester body. The top surface of the box body is provided with a flattening structure for flattening the wrinkles of the plastic bag. The flattening structure includes a plurality of placement blocks fixed to the top surface of the box body. The plurality of placement blocks are spaced apart. The top surface of the box body is provided with a tensioning frame. The tensioning frame is slidably inserted into the gap between the tensioning frame and the plurality of placement blocks.

[0007] As a further embodiment of this utility model, two mounting plates are fixed on the inner top surface of the box, and a screw is rotatably arranged between the two mounting plates. A connecting plate is threadedly connected to the outer circular wall of the screw, and a pressure plate is provided at one end of the connecting plate. The bottom surface of the pressure plate abuts against the top surface of the tensioning frame.

[0008] As a further embodiment of this utility model, one end of the connecting plate is rotatably connected to one end of the pressure plate.

[0009] As a further embodiment of this utility model, a magnetic strip is fixed on the inner top surface of the box, and the magnetic strip is magnetically connected to the tensioning frame.

[0010] As a further embodiment of this utility model, a guide rod is fixed between the two mounting plates, and the guide rod is slidably inserted into the connecting plate.

[0011] As a further embodiment of this utility model, a fixing groove is provided on the bottom surface of the inner side of the box, and the fixing groove corresponds to the shape of the thickness measuring instrument body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This air collection device, through its flattening structure, lays a plastic bag flat on multiple placement blocks. A tensioning frame presses onto the plastic bag and inserts into the gaps between the placement blocks. During insertion, the tensioning frame pulls the plastic bag into the gaps, tightening the plastic bag located on the top surface of the placement blocks. This flattens out the wrinkles within the tensioned area and divides the plastic bag into multiple detection zones. Rotating the screw moves the pressure plate downwards and fits against the tensioning frame, achieving a stable fixation of the tensioning frame and the plastic bag. Finally, the user measures each area of ​​the plastic bag using the detection probe of the thickness measuring instrument. By flattening out wrinkles during the plastic bag fixing process, the accuracy of thickness detection is effectively improved. Attached Figure Description

The top surface of the housing 1 is provided with a flattening structure for flattening the wrinkles of the plastic bag. The flattening structure includes a plurality of placement blocks 201 fixed to the top surface of the housing 1. The plurality of placement blocks 201 are spaced apart. The top surface of the housing 1 is provided with a tensioning frame 202. The tensioning frame 202 is slidably inserted into the gap between the tensioning frame 202 and the plurality of placement blocks 201.

[0023] In this embodiment, two mounting plates 203 are fixed to the inner top surface of the housing 1. A screw 204 is rotatably arranged between the two mounting plates 203. A connecting plate 205 is threadedly connected to the outer circular wall of the screw 204. A pressure plate 206 is provided at one end of the connecting plate 205. The bottom surface of the pressure plate 206 abuts against the top surface of the tensioning frame 202. Through the flattening structure, the user can lay the plastic bag flat on multiple placement blocks 201, then press the tensioning frame 202 onto the plastic bag and insert it into the gap between the placement blocks 201. During the insertion process, the tensioning frame 202... The plastic bag is moved into the gap, causing the plastic bag located on the top surface of the placement block 201 to be tightened, thereby flattening the wrinkles in the tension area and dividing the plastic bag into multiple detection areas. Then, the user rotates the screw 204, causing the pressure plate 206 to move downward. The pressure plate 206 presses down and adheres to the tension frame 202, achieving a stable fixation of the tension frame 202 and the plastic bag. Finally, the user measures each area of ​​the plastic bag through the detection probe of the thickness measuring instrument body 2. The wrinkles are flattened during the fixing process of the plastic bag, effectively improving the accuracy of thickness detection.

[0024] In this embodiment, one end of the connecting plate 205 is rotatably connected to one end of the pressure plate 206. After the test is completed, the user can pry open the pressure plate 206 and quickly remove the tensioning frame 202 and the plastic bag, which is convenient for the user to operate.

[0025] In this embodiment, a magnetic strip 3 is fixed on the inner top surface of the box 1. The magnetic strip 3 is magnetically connected to the tension frame 202. The tension frame 202 is made of ferromagnetic plastic. When the box 1 is closed and carried, the tension frame 202 is magnetically attracted to the magnetic strip 3 inside the box 1, thereby fixing the position of the tension frame 202 inside the box 1.

[0026] In this embodiment, a guide rod 4 is fixed between the two mounting plates 203. The guide rod 4 is slidably inserted into the connecting plate 205. When the connecting plate 205 moves up and down under the action of the screw 204, the guide rod 4 guides and limits the movement of the connecting plate 205, making its movement more stable.

[0027] In this embodiment, a fixing groove 5 is provided on the bottom surface of the inner side of the housing 1. The fixing groove 5 corresponds to the shape of the thickness measuring instrument body 2. The thickness measuring instrument body 2 can be safely fixed inside the housing 1 through the fixing groove 5.

[0028] Working principle: In use, the user lays the plastic bag flat on multiple placement blocks 201, then presses the tensioning frame 202 onto the plastic bag and inserts it into the gap between the placement blocks 201. During insertion, the tensioning frame 202 pulls the plastic bag into the gap, tightening the plastic bag located on the top surface of the placement block 201, thus smoothing out wrinkles within the tensioning area and dividing the plastic bag into multiple detection zones. Subsequently, the user rotates the screw 204, causing the pressure plate 206 to move downwards. The pressure plate 206 presses down and adheres to the tensioning frame 202, achieving a stable fixation of the tensioning frame 202 and the plastic bag. Finally, the user... The user measures each area of ​​the plastic bag using the detection probe of the thickness measuring instrument body 2. After the test is completed, the user can open the pressure plate 206 and quickly remove the tensioning frame 202 and the plastic bag for easy operation. When the case 1 is closed for carrying, the tensioning frame 202 is magnetically attracted to the magnetic strip 3 inside the case 1, thereby fixing the position of the tensioning frame 202 inside the case 1. When the connecting plate 205 moves up and down under the action of the screw 204, the guide rod 4 guides and limits the movement of the connecting plate 205, making its movement more stable. The thickness measuring instrument body 2 can be safely fixed inside the case 1 through the fixing groove 5.
