Description

Technical Field

[0001] This utility model relates to the field of plastic woven bag production and testing technology, and more specifically, to a plastic woven bag thickness detection device with adjustable spacing. Background Technology

[0002] Woven plastic bags, also known as snake-skin bags, are a type of plastic bag used for packaging. They are typically made of polypropylene or other types of plastic, and their thickness directly affects their strength and durability. By testing the thickness, it can be ensured that the bags will not easily break or be damaged when subjected to heavy loads or used in harsh environments. Therefore, during the production process, it is necessary to use testing equipment to check the thickness of the woven bags.

[0003] Traditional food packaging bag thickness testing devices cannot automatically test a group of food packaging bag films, nor can they automatically adjust the position of the food packaging bag films, requiring manual handling and movement of the food packaging bag films.

[0004] A search revealed that Chinese patent CN223216879U discloses a food packaging bag thickness detection device. This device, comprising a lifting adjustment frame, a conveyor belt body, and a conveyor belt motor, allows for the detection of a set of food packaging bag films. The lifting adjustment frame can automatically rise and fall, automatically adjusting the food packaging bag film forward, backward, left, and right without requiring manual movement. The conveyor belt body and conveyor belt motor continuously supply food packaging bag film sheets to the area below the detection probe.

[0005] In actual use, the aforementioned food packaging bag thickness detection device is prone to wrinkles or bends due to folding or squeezing during the production or handling of plastic woven bags. This causes the detection head of the detector to come into contact with the wrinkled area when it comes into contact with the surface of the plastic woven bag, resulting in deviations in the thickness measurement data. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a plastic woven bag thickness detection device with adjustable spacing to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

A limiting groove adapted to the leveling rod is provided on the front side of the connecting housing, and the inner side of the limiting groove is slidably connected to the leveling rod.

[0010] By adopting the above technical solution, the surface of the plastic woven bag can be flattened, thereby reducing the impact of wrinkles on the detection.

[0011] As a further description of the above technical solution: the fixing mechanism includes a support base, which is fixedly connected to one side of the fixing frame. A second stepper motor is fixedly connected to one side of the fixing frame. A threaded rod is fixedly connected to the output end of the second stepper motor. The bottom end of the threaded rod is rotatably connected to the support base. A movable outer shell is threadedly connected to the outer side of the threaded rod. The movable outer shell is slidably connected to the fixing frame. A third electric push rod is installed on both sides of the movable outer shell.

A connecting rod is fixedly connected to one side of the push plate. A stop block is fixedly connected to the outer side of the connecting rod.

[0012] By adopting the above technical solution, the plastic woven bag can be straightened at the bag opening, thereby eliminating the interference of bag opening deformation and improving measurement accuracy.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1.

A connecting shaft 10 is fixedly connected to one side of both the first gear 8 and the second gear 9. A swing rod 11 is fixedly connected to the outer side of the connecting shaft 10. A leveling rod 12 is rotatably connected to the bottom end of the swing rod 11 via a bearing. The bottom end of the leveling rod 12 is arc-shaped.

The inner side of the slide groove 14 is slidably connected to the slider 13. The front side of the connecting shell 6 is provided with a limiting groove 15 that is adapted to the flattening rod 12. The inner side of the limiting groove 15 is slidably connected to the flattening rod 12. The connecting shell 6 can be pushed down by the second electric push rod 5 so that the two flattening rods 12 can contact the surface of the plastic woven bag that is straightened and placed at the top of the detection table 4. Then, the two swing rods 11 can swing to drive the flattening rod 12 to move. The slide groove 14 can limit the movement of the flattening rod 12. The slider 13 can slide with the inner side of the slide groove 14 to provide guidance for the flattening rod 12 so that the two flattening rods 12 can move relative to each other to flatten the wrinkles of the plastic woven bag, so that the measuring head of the thickness measuring instrument 3 can make uniform contact with the surface of the bag, thereby obtaining a more accurate thickness value.

[0026] Reference Figure 2 and 6 As shown, the fixing mechanism includes a support base 16, which is fixedly connected to one side of the fixing frame 1. A second stepper motor 17 is fixedly connected to one side of the fixing frame 1. A threaded rod 18 is fixedly connected to the output end of the second stepper motor 17. The bottom end of the threaded rod 18 is rotatably connected to the support base 16. A movable housing 19 is threadedly connected to the outer side of the threaded rod 18. The movable housing 19 is slidably connected to the fixing frame 1. A third electric push rod 20 is installed on both sides of the movable housing 19. A push plate 21 is fixedly connected to the output end of the third electric push rod 20. The push plate 21 is slidably connected to the inner side of the movable housing 19. A connecting rod 22 is fixedly connected to one side of the push plate 21. A stop block 23 is fixedly connected to the outer side of the connecting rod 22. By using the two third electric push rods 20 to pull the push plate 21, the push plate 21 can drive the connecting rod 22 to move, thereby allowing the two connecting rods 22 to be stretched at the opening of the plastic woven bag. This can eliminate the interference of bag opening deformation and assist the flattening work of the two flattening rods 12, thereby improving the measurement accuracy.

[0027] Working principle of this utility model: This utility model designs an adjustable-spacing plastic woven bag thickness detection device, the specific structure of which is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation between various structures, when the thickness of a plastic woven bag needs to be detected, the bag opening is first placed outside the two connecting rods 22 and the bag opening is brought into contact with the stop block 23. Then, the two third electric push rods 20 are activated simultaneously by the external controller, causing the third electric push rods 20 to pull the push plate 21 to move. In turn, the push plate 21 can pull the connecting rods 22 to move, so that the two connecting rods 22 can support the bag opening and fix the plastic woven bag. Then, the second stepper motor 17 is activated, which drives the threaded rod 18 to rotate. Through the action of the thread on the outside of the threaded rod 18, the movable shell 19 can be driven to move the plastic woven bag downward, so that the plastic woven bag can be placed on the detection table 4. Then, the second electric push rod 5 is activated, which pushes the connecting shell 6 downward, so that the two flattening rods 12 are in contact with the surface of the plastic woven bag. The system touches and starts the first stepper motor 7, which drives the first gear 8 to rotate. The first gear 8 can mesh with and drive the second gear 9 to rotate, so that the first gear 8 and the second gear 9 can drive the two swing rods 11 to swing through the connecting shaft 10. The outside of the flattening rod 12 is rotatably connected to the swing rod 11 through the bearing, so that the swing rod 11 can drive the flattening rod 12 to move when swinging. The slide groove 14 can limit the outside of the flattening rod 12, and the slider 13 is slidably connected to the inside of the slide groove 14, thereby limiting the swing trajectory of the swing rod 11 and the moving direction of the flattening rod 12, so that the two flattening rods 12 can move in opposite directions. The rounded design of the bottom end of the flattening rod 12 can flatten the wrinkles on the surface of the plastic woven bag, so that the surface of the plastic woven bag remains flat. Then, the first electric push rod 2 is started, which pushes the thickness detector 3 to press down on the plastic woven bag, so that the thickness of the plastic woven bag can be detected.
