Description

Technical Field

[0001] This utility model relates to the field of plastic bag inspection technology, and in particular to a plastic bag inspection device. Background Technology

[0002] Plastic bags are bags made primarily of plastic (common plastics include polypropylene, polyester, nylon, etc.). They are essential items in people's daily lives and are often used to hold other items. To ensure the quality standards of plastic bags, they are usually sampled and tested.

[0003] However, in existing technologies, tensile testing devices for plastic bags typically fix both ends of the plastic bag at a single point, which leads to an overly concentrated application of tensile force. This results in the plastic bag being subjected to greater force during testing than it would be in actual use, affecting the evaluation and judgment. Therefore, we propose a plastic bag quality inspection device. Utility Model Content

[0004] This invention provides a plastic bag quality inspection device that solves the above-mentioned technical problems.

[0005] The present invention provides the following solution to the above-mentioned technical problems: A plastic bag inspection device includes a base plate, a top plate above the base plate, the top plate being fixedly connected to the base plate by multiple support rods, a tension detector mounted on the top plate by a tension control mechanism, a connecting block fixedly mounted at the lower end of the tension detector, a U-shaped mounting plate fixedly mounted on the lower end face of the connecting block and the upper end face of the base plate respectively, two symmetrically arranged movable plates mounted on the surface of the mounting plates by a sliding mechanism, the movable plates being connected to a movable adjustment mechanism, a fixing block fixedly mounted on the surface of the movable plates, and a squeezing block mounted on the surface of the movable plates by an elastic mechanism, with fixing pads fixedly mounted on the opposite faces of the squeezing block and the fixing block respectively.

[0006] Preferably, the tension control mechanism includes an electric push rod that is vertically fixedly installed on the upper surface of the top plate, and the free end of the electric push rod movably passes through the top plate and is fixedly connected to the tension detector.

[0007] Preferably, the sliding mechanism includes a groove laterally formed on the surface of the mounting plate, and the moving plate is slidably connected to the inner wall of the groove.

[0008] Preferably, the movable adjustment mechanism includes a screw that is laterally rotatably mounted on the outer wall of the movable plate, the screw thread passing through the mounting plate.

[0009] Preferably, the elastic mechanism includes an auxiliary block fixedly installed on the surface of the movable plate, and a pull rod that movably passes through the auxiliary block is fixedly installed laterally on the outer wall of the extrusion block. The outer wall of the extrusion block is laterally fixedly connected to the auxiliary block by a spring that is movably sleeved on the outer wall of the pull rod.

[0010] The beneficial effects of this utility model are:

[0011] 1. By setting two mounting plates, and setting two sets of fixing blocks and squeezing blocks on the two mounting plates respectively, the plastic bag is fixed at multiple points, and the force on the plastic bag is distributed, making the force on the plastic bag more even. At the same time, fixing pads are set on the opposite surfaces of the fixing blocks and squeezing blocks, making the device clamp and fix the plastic bag more stable.

[0012] 2. By setting a movable plate, the movable plate can be moved by a screw, so that the position of the movable plate can be adjusted according to the plastic bags of different sizes, making it easier to clamp and fix plastics of different sizes, and making it more versatile.

[0020] The following is in conjunction with the appendix Figure 1-3The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0021] like Figure 1-3 As shown, this utility model discloses a plastic bag inspection device, including a base plate 1 and a top plate 2 above the base plate 1. The top plate 2 is fixedly connected to the base plate 1 by multiple support rods 3. A tension detector 4 is installed on the top plate 2 through a tension control mechanism. The tension control mechanism includes an electric push rod 10 vertically fixedly installed on the upper surface of the top plate 2. The free end of the electric push rod 10 movably passes through the top plate 2 and is fixedly connected to the tension detector 4. The electric push rod 10 can indirectly pull the upper mounting plate 6 upward to realize the tension detection of the plastic bag. The tension detector 4 is set to detect the tension of the plastic bag, making the tension of the plastic bag more intuitive. A connecting block 5 is fixedly installed at the lower end of the tension detector 4. A gate-shaped mounting bracket is fixedly installed on the lower surface of the connecting block 5 and the upper surface of the base plate 1, respectively. The mounting plate 6 has two symmetrically arranged movable plates 7 mounted on its surface via a sliding mechanism. The sliding mechanism includes a horizontally opened groove on the surface of the mounting plate 6. The movable plates 7 are slidably connected to the inner wall of the groove. The movable plates 7 are connected to a movable adjustment mechanism. A fixing block 8 is fixedly mounted on the surface of the movable plates 7. A squeezing block 9 is mounted on the surface of the movable plates 7 via an elastic mechanism. Fixing pads are fixedly mounted on the opposite sides of the squeezing block 9 and the fixing block 8, respectively. This device uses two mounting plates 6, one above the other, and two sets of movable fixing components on each of the two mounting plates 6 to fix the plastic bag at multiple points, disperse the force, and make the detected force more similar to the force experienced by the plastic bag during actual use. At the same time, the fixing components can be controlled to move using a screw 11, making it suitable for plastic bags of different sizes.

[0022] Specifically, the movable adjustment mechanism includes a screw 11 that is horizontally rotatably mounted on the outer wall of the movable plate 7. The screw 11 is threaded through the mounting plate 6. Rotating the screw 11 can drive the movable plate 7 to move, thereby adjusting the position of the movable plate 7 to match different sizes of plastic bags.

[0023] More specifically, the elastic mechanism includes an auxiliary block fixedly installed on the surface of the movable plate 7. A pull rod 12 that moves through the auxiliary block is fixedly installed laterally on the outer wall of the extrusion block 9. The outer wall of the extrusion block 9 is fixedly connected to the auxiliary block by a spring 13 that is movably sleeved on the outer wall of the pull rod 12. The spring 13 pushes the extrusion block 9 to cooperate with the fixed block 8 to achieve the extrusion and fixation of the plastic bag, ensuring that the upper and lower mounting plates 6 can realize the stretch detection of the plastic bag. The pull rod 12 can quickly cancel the extrusion block 9's extrusion and fixation of the plastic bag.

[0024] Working principle:

[0025] In use, rotating screw 11 drives moving plate 7 to move, controlling moving plate 7 to move to the target position and match the plastic bag to be tested. Pulling the lower pulling rod 12, pulling rod 12 drives the corresponding squeezing block 9 to overcome the force of spring 13 and move away from fixed block 8. Place one end of the plastic bag between fixed block 8 and squeezing block 9. Repeat the above steps to fix the plastic bag with four sets of fixed blocks 8 and squeezing blocks 9. Then control electric push rod 10 to retract and drive upper mounting plate 6 to move upward. As the distance between the two mounting plates 6 increases, the plastic bag is stretched. At the same time, tension sensor 4 displays the tension reading of the plastic bag until the plastic bag is stretched and deformed, completing the test.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
