[0002] Plastic woven bags, also known as snakeskin bags, are a type of plastic. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. Woven bags have a wide range of uses, mainly used for the packaging and packaging of various items. They are widely used in industry. The processing sequence of plastic woven bags is generally to print, cut, and sew the woven cloth into woven bags. In the production of plastic woven bags, quality inspection is often an indispensable step, and it is usually necessary to test the strength of plastic woven bags.

[0052] The gas from the external air pump of the circular tube 110 enters the air bag 104 through the air outlet 111 .

[0053] In this embodiment, the method for using the detection equipment for producing plastic woven bags comprises the following steps:

[0054] Step 1: After the external power supply is connected, the external air pump is connected through the round tube 110, and then the second electric telescopic rod 109 is controlled to extend through the control panel 2. The second electric telescopic rod 109 drives the first clamping ring 102 to rise through the electromagnet 101, and then one end of the woven bag is sleeved on the first sealing ring 103, and then pulled down, sleeved on the outer wall of the second sealing ring 105, and then passed through the second clamping ring 106. Operate the control panel 2 to cut off the power of the electromagnet 101, the electromagnet 101 no longer attracts the first clamping ring 102, and the first clamping ring 102 will fall off, and then the upper end of the woven bag is passed through the middle of the first clamping ring 102, and then the second electric telescopic rod 109 is controlled to shrink through the control panel 2, and the second electric telescopic rod 109 drives the electromagnet 101 descends and squeezes the first clamp ring 102. When the first clamp ring 102 is clamped on the outer wall of the first sealing ring 103, the upper side of the woven bag is clamped and sealed by the first clamp ring 102 and the first sealing ring 103. Then, the control panel 2 controls the first electric telescopic rod 108 to extend, driving the support ring 107 to squeeze the second clamp ring 106. When the second clamp ring 106 is clamped on the outer wall of the second sealing ring 105, the lower side of the woven bag is clamped and sealed by the second clamp ring 106 and the second sealing ring 105. At this time, both ends of the woven bag are clamped. Then, the external air pump is ventilated and discharged from the round tube 110 through the air outlet 111. The gas enters the airbag 104. The airbag 104 gradually becomes larger and is filled and abuts against the inner wall of the woven bag, so that the inner wall of the woven bag is fully stressed.

[0055] Step 2: As the airbag 104 becomes larger, the pressure on the woven bag increases, and the tension sensor 112 detects the tension, thereby testing the overall strength and tensile strength of the woven bag;

[0056] Step 3: After the overall strength and tensile performance of the woven bag are tested, the control panel 2 is used to control the third electric telescopic rod 205 to extend, driving the friction plate 206 to contact the woven bag, and then controlling the first servo motor 4 to rotate, the first servo motor 4 drives the second gear 5 to rotate, the second gear 5 drives the first gear 3 to rotate, the first gear 3 drives the round tube 110 to rotate, the round tube 110 drives the woven bag on the outer wall of the airbag 104 to rotate through the first sealing ring 103 and the second sealing ring 105, at this time, the second clamping ring 106 rotates on the supporting ring 107, and when the round tube 110 rotates, it will drive the sun gear 209 to rotate.
