Description

Technical Field

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

[0002] Among the many packaging materials, flexible materials such as plastic film and fiberboard are widely used. Taking plastic film as an example, it is often used to directly wrap household appliances, serving as a dustproof, moisture-proof, and initial cushioning agent. The tensile strength of these materials is crucial. If the packaging material has insufficient tensile strength, the plastic film is prone to tearing when it encounters bumps and compression during transportation.

[0003] Referring to the patent with announcement number CN221377472U, a tensile testing device for nanoplastic films is disclosed. In this utility model, when the nanoplastic film is stretched, it will drive the spring balance to move, thereby measuring the force applied to the nanoplastic film and making it easy to obtain the accurate bearing capacity of the nanoplastic film at room temperature.

[0004] However, the aforementioned tensile testing equipment for plastic films used in appliance packaging requires repeated twisting of bolts to install or remove the flipping strips during the installation or removal of the plastic film to be tested, thus securing the material for testing. This operation is extremely cumbersome, consuming a significant amount of time with each installation or removal, severely impacting the efficiency of the testing process. Summary of the Invention

[0028] like Figure 1 - Figure 5 and Figure 7 As shown in the figure, this embodiment provides a home appliance packaging inspection device, including a base 1, a support plate 2 on one side of the top of the base 1, a slide rod 3 symmetrically arranged on one side of the support plate 2 at the top of the base 1, a screw 4 rotatably installed on one side of the support plate 2 between the slide rods 3, a threaded movable plate 6 sleeved on the outside of the screw 4, and the two ends of the movable plate 6 slidably sleeved on the outside of the slide rods 3, a clamping strip 7 arranged on one side of the movable plate 6 above the slide rods 3, a pressure rod 9 hinged to the top of the clamping strip 7 and the movable plate 6 respectively, and one end of the pressure rod 9 is connected to the movable plate 6 and the clamping strip 7 respectively through a fixing mechanism, and a connecting component is connected to the bottom of the clamping strip 7; the fixing mechanism includes a ratchet 12, and the ratchet 12 is arranged at one end of the pressure rod 9, a groove is opened on the side of the ratchet 12 near the pressure rod 9, a slider 11 is arranged in the groove, and the slider 11 is fixedly connected to the pressure rod 9.

[0029] In this example, the fixing mechanism also includes a mounting box 13, which is fixedly mounted on one end of the movable plate 6. The lower end of the ratchet 12 passes through the mounting box 13. A rotating shaft 14 is rotatably mounted inside the mounting box 13 on one side of the ratchet 12. A pawl 16 and a torsion spring 17 are sleeved on the outside of the rotating shaft 14. The two ends of the torsion spring 17 are fixedly connected to the rotating shaft 14 and the mounting box 13, respectively. One end of the pawl 16 engages with the ratchet 12 so that the ratchet 12 can be limited by the cooperation of the ratchet 12 and thus the position of the pressure rod 9 can be fixed so as to quickly clamp and fix the plastic film, thereby improving its working efficiency.

[0030] In this example, the fixing mechanism also includes a sliding sleeve 15, which is slidably sleeved on the outside of the rotating shaft 14. A pawl 16 is fixedly sleeved on the outside of the sliding sleeve 15. A connecting plate 18 is rotatably sleeved on the outside of the sliding sleeve 15 on the side of the pawl 16 away from the torsion spring 17. A push rod 19 is connected to one side of the connecting plate 18, and one end of the push rod 19 extends to the outside of the mounting box 13. A spring 20 is sleeved on the outside of the sliding sleeve 15 and the rotating shaft 14 on the side of the connecting plate 18 away from the pawl 16. The two ends of the spring 20 are fixedly connected to the connecting plate 18 and the mounting box 13 respectively, so as to push the push rod 19 and drive the pawl 16 to be displaced and separated from the ratchet 12, so as to disassemble the pressure rod 9 and remove the plastic film for testing.

[0031] In this example, the bottom of the pressure rod 9 is connected to the extrusion strip 10, and the top of the moving plate 6 and the clamping strip 7 are both provided with extrusion grooves that are adapted to the extrusion strip 10, so as to extrude and fix the plastic film and improve the clamping effect.

[0032] In this example, an anti-slip plate 21 is provided at the bottom of the extrusion groove. The anti-slip plate 21 and the extrusion strip 10 have wavy curved surfaces on their opposite walls to improve the fixing effect on the plastic film and enhance the anti-slip effect.

[0033] like Figure 1 , Figure 2 and Figure 6 As shown in this example, a scale 5 is provided on the top of the base 1 below the screw 4, and the scale 5 passes through the moving plate 6. A pointer adapted to the scale 5 is provided on one side of the moving plate 6. A magnifying glass 24 is provided on one side of the moving plate 6 above the pointer, and the magnifying glass 24 is detachably connected to the moving plate 6 by bolts. A spring force gauge 8 is connected to one side of the clamping strip 7, and the spring force gauge 8 is fixedly connected to the support plate 2 so as to intuitively understand the amount of stretching of the plastic film.

[0034] In this example, slide blocks 22 are slidably mounted on the outer side of the slide rod 3, and the upper end of the slide block 22 is fixedly connected to the clamping bar 7. Several balls 23 are rotatably embedded in the inner wall of the slide block 22. The outer wall of the slide rod 3 is provided with a groove that matches the balls 23, so as to support and guide the clamping bar 7 and improve its stability.

[0035] In use, the two ends of the plastic film to be tested are placed on the top of the moving plate 6 and the clamping strip 7, respectively. Then, the reverse pressure rod 9 drives the extrusion strip 10 to press into the corresponding extrusion groove, thus squeezing and fixing the plastic film. Then, the ratchet 12 is pushed down under the limiting guide of the slider 11, so that the ratchet 12 pushes one end of the pawl 16, which drives the sliding sleeve 15 and then drives the rotating shaft 14 to rotate. At the same time, the rotating shaft 14 twists the torsion spring 17. When the pawl 16 corresponds to the groove on the ratchet 12, the torsion of the torsion spring 17 will cause the pawl 16 to reset and rotate, thus engaging with the ratchet 12. This process is repeated, so that the ratchet 12 drives the pressure rod 9 down, thus pressing and fixing the plastic film. The system allows for quick installation to improve testing efficiency. After testing, the restriction on the pressure rod 9 can be lifted, and then the push rod 19 can be pushed to drive the connecting plate 18, which in turn causes the connected sliding sleeve 15 to slide on the rotating shaft 14. At the same time, the sliding sleeve 15 will drive the connected pawl 16 to move synchronously, causing it to be misaligned with the ratchet 12, thus lifting the restriction on the ratchet 12. Then, the ratchet 12 can be pulled up to separate it from the mounting box 13, and then the pressure rod 9 can be lifted to remove the plastic film, making it convenient to use. Furthermore, by using the pointer on one side of the moving plate 6 to correspond to the scale value on the ruler 5, and with the magnification of the magnifying glass 24, the amount of stretching of the plastic film can be intuitively understood, making it even more convenient to use.

[0036] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
