Detailed implementation mode

[0018] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. Typical embodiments of the present utility model are shown in the drawings.

[0019] Embodiment: A packaging bag stretching device with a pressing function, including a base 1, a detection table 2 is fixedly connected above the base 1, a barrel groove 6 is opened above the detection table 2, and a detection component 3 is arranged in the inner cavity of the detection table 2. The detection component 3 penetrates through the barrel groove 6 and extends outwards. A reading component 4 is arranged outside the detection table 2. The reading component 4 penetrates through the detection table 2 and is connected with the detection component 3. Among them, in order to improve the stability of the device, legs 5 are fixedly connected below the base 1.

[0020] The detection component 3 includes a rotating rod 32 rotatably connected to the inner wall of the detection table 2. The rotating rod 32 penetrates through the detection table 2 and is fixedly connected with a motor 31. The motor 31 is fixedly installed above the base 1. The outer side of the rotating rod 32 is provided with a first thread 33 and a second thread 34.

The threaded seats 35 penetrate through the barrel groove 6 and are connected with a pressing component. A guide seat 36 is arranged outside the pressing component. A guide rod 37 is slidably connected to the outer side of the guide seat 36. Both ends of the guide rod 37 are connected to the inner wall of the detection table 2. The pressing component includes a U-shaped frame 38 fixedly connected above the guide seat 36. A pressing plate 39 is movably connected to the inner cavity of the U-shaped frame 38. An outer side of the pressing plate 39 is fixedly connected with a movable rod 310. The movable rod 310 penetrates through the U-shaped frame 38 and is fixedly connected with a pulling plate 311. A spring 312 is sleeved on the outer side of the movable rod 310. Both ends of the spring 312 are fixedly connected with the U-shaped frame 38 and the pressing plate 39 respectively.

[0021] Specifically, when a tensile test needs to be performed on the packaging bag, first pull the pull plate 311 upward. When the pull plate 311 moves, it will drive the movable rod 310 fixedly connected to it to move upward, so that the movable rod 310 drives the pressing plate 39 fixedly connected to it to move. When the pressing plate 39 moves, it will compress the spring 312 fixedly connected to it. Then, place the two ends of the packaging bag under the two pressing plates 39 respectively, and then remove the force on the pull plate 311, so that the pressing plate 39 presses the packaging bag through the elastic force of the spring 312. Then, control the motor 31 to work, so that the motor 31 drives the rotating rod 32 fixedly connected to its output shaft to rotate. When the rotating rod 32 rotates, it will drive the first thread 33 and the second thread 34 to rotate, so that the two thread seats 35 move away from each other. When the thread seats 35 move, they will drive the U-shaped frame 38 fixedly connected to them to move synchronously, so as to perform a tensile test on the packaging bag.

A rotating shaft 413 is fixedly connected to the outside of the pointer 44. A driven wheel 412 is fixedly connected to the outside of the rotating shaft 413. A belt 411 is sleeved on the outside of the driven wheel 412, and the driven wheel 412 is connected with a driving wheel 410 through the belt 411. A transmission assembly is arranged on the outside of the driving wheel 410. The transmission assembly includes a bearing bracket 45 fixedly connected to the outside of the detection table 2.

One end of the connecting rod 46 is fixedly connected with the driving wheel 410, and the other end of the connecting rod 46 is fixedly connected with a driving bevel gear 47. A driven bevel gear 48 is meshed with the outside of the driving bevel gear 47. A driving shaft 49 is fixedly connected to the outside of the driven bevel gear 48. The driving shaft 49 penetrates through the detection table 2 and is fixedly connected with the rotating rod 32.

[0023] Specifically, when the rotating rod 32 rotates, it will drive the driving shaft 49 fixedly connected to it to rotate, so that the driving shaft 49 drives the driven bevel gear 48 fixedly connected to it to rotate. When the driven bevel gear 48 rotates, it will drive the driving bevel gear 47 meshed with it to rotate. When the driving bevel gear 47 rotates, it will drive the connecting rod 46 fixedly connected to it to rotate, so that the connecting rod 46 drives the driving wheel 410 fixedly connected to it to rotate. When the driving wheel 410 rotates, it will drive the driven wheel 412 to rotate through the belt 411, so that the driven wheel 412 drives the rotating shaft 413 fixedly connected to it to rotate. When the rotating shaft 413 rotates, it will drive the pointer 44 fixedly connected to it to rotate, so as to facilitate judging the tensile quality of the packaging bag according to the position where the pointer 44 points on the scale lines 43.
