It can also evaluate and analyze the compressive strength, bursting strength and other indicators of the materials used in flexible packaging bags.

[0003] When testing the sealing performance of the existing heat-sealed rubber strips, the existing equipment needs to first stick the rubber strips to the seams of the fabric, then use an annular pressing plate to press and seal the fabric, and then release water from the middle of the pressing plate to squeeze the fabric, thereby achieving the test. However, the seams of the fabric are thicker, and when sealing, since the thickness of the connection between the two pieces of fabric is thicker than other places, water is likely to flow out of the seams of the fabric when the annular pressing plate is sealed, resulting in insufficient water pressure, which is prone to accidental leakage.

[0021] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 — Figure 6As shown, this embodiment provides a heat-sealed adhesive strip sealing detection device, including a frame 1, a pressurizing system 2, an upper pre-pressing system 3, a lower pre-pressing system 4, an upper sealing system 5, an upper coating system 6, a lower sealing system 7, a lower coating system 8 and a water pressure system 91. The pressurizing system 2 is installed on the frame 1, so as to generate downward pressure on the surrounding of the fabric and realize pressurized sealing of the fabric. The water pressure system 91 is installed on the frame 1. The water pressure system 91 is provided with a water outlet on the lower side of the pressurizing system 2, so as to generate and maintain a predetermined water pressure. The water pressure system 91 is a conventional water pump pressurization method, which will not be repeated here. The upper pre-pressing system 3 is rotatably installed on the lower side of the pressurizing system 2, and the lower pre-pressing system 4 is rotatably installed on the frame 1. The upper pre-pressing system 3 and the lower pre-pressing system 4 are arranged relative to each other. Before the pressurizing system 2 is pressurized and the water outlet discharges water, the fabric is placed on the upper pre-pressing system 3 and the lower pre-pressing system 4. 4, then drive the pressurizing system 2 downward, so that the upper pre-pressing system 3 and the lower pre-pressing system 4 clamp the cloth, after manually rotating the cloth, the cloth and the upper smearing system 6 and the lower smearing system 8 are mutually shifted, so that the upper smearing system 6 and the lower smearing system 8 can spread butter on the cloth to enhance the sealing effect, the upper sealing system 5 is installed on the lower side of the pressurizing system 2, the upper sealing system 5 is located on the inner side of the upper pre-pressing system 3, the lower sealing system 7 is installed on the frame 1, the lower sealing system 7 is located on the inner side of the lower pre-pressing system 4, the water outlet is located on the inner side of the lower sealing system 7, the upper smearing system 6 is installed in the upper sealing system 5, the upper smearing system 6 has an upper smearing port exposing the surface of the upper sealing system 5, so as to realize the smearing of butter on the upper side of the cloth, the lower smearing system 8 is installed in the lower sealing system 7, the lower smearing system 8 has a lower smearing port exposing the surface of the lower sealing system 7, so as to realize the smearing of butter on the lower side of the cloth, and ensure reliable detection.

[0022] The detection principle and steps of the heat-sealing strip sealing detection device are as follows: The pressurizing system 2 is lifted, and then the upper pre-pressing system 3 is lifted, so as to facilitate the placement of the fabric to be tested, and the fabric to be tested is placed between the upper pre-pressing system 3 and the lower pre-pressing system 4. Then the pressurizing system 2 drives the upper pre-pressing system 3 to descend, and the upper pre-pressing system 3 and the lower pre-pressing system 4 clamp the fabric and pull the fabric to rotate. The upper smearing system 6 and the lower smearing system 8 squeeze out butter, and then smear butter on the sealing position between the upper sealing system 5 and the lower sealing system 7 and the fabric to avoid water leakage from between the upper sealing system 5 and the fabric or between the lower sealing system 7 and the fabric, so as to ensure reliable detection.

[0023] It is worth noting that the lower coating system 8 close to the water pressure system 91 is the one that actually plays a sealing role, and the upper coating system 6 is set at a position corresponding to the lower coating system 8 because butter not only has a sealing function but also a lubricating function. If the upper coating system 6 is not set, the cloth will only rub against the upper sealing system 5 after deformation, causing the upper sealing system 5 to be easily damaged. Therefore, the upper coating system 6 is set to protect the detection equipment.

[0024] Specifically, the pressurizing system 2 includes a pressurizing bracket 21, a pressurizing screw 22 and a pressurizing ring 23. The pressurizing ring 23 is rotatably mounted on the bottom of the pressurizing screw 22 through a guide bracket 231. The guide bracket 231 is rotatably mounted on the bottom of the pressurizing screw 22 through a thrust bearing. In order to ensure the stable thrust of the pressurizing screw 22 and prevent the pressurizing screw 22 from deflecting, a guide sleeve slidably connected to the pressurizing bracket 21 is provided on the guide bracket 231, thereby ensuring the stable pressure of the pressurizing ring 23. The pressurizing bracket 21 is mounted on the frame 1, and the pressurizing screw 22 is mounted on the pressurizing bracket 21 through a threaded pair. The pressurizing screw 22 is rotated to generate pressure.

[0025] Specifically, the upper preload system 3 includes an upper preload bearing 31, an upper preload flexible ring 32 and an upper preload ring 33. The upper preload bearing 31 is installed on the lower side of the pressurizing system 2. The upper preload ring 33 is installed on the upper preload bearing 31 through the upper preload flexible ring 32. The upper preload ring 33 is arranged relative to the lower preload system 4. The upper preload bearing 31 allows the upper preload ring 33 to rotate.

[0026] Specifically, the lower preload system 4 includes a lower preload bearing 41, a lower preload flexible ring 42 and a lower preload ring 43. The lower preload bearing 41 is installed on the upper side of the frame 1, and the lower preload ring 43 is installed on the lower preload bearing 41 through the lower preload flexible ring 42. The lower preload ring 43 and the upper preload system 3 are arranged relative to each other. The lower preload bearing 41 allows the lower preload ring 43 to rotate. Before the upper sealing system 5 and the lower sealing system 7 squeeze and seal, the upper preload ring 33 and the lower preload ring 43 clamp the cloth and rotate, so that butter is applied to the upper and lower ends of the cloth.

[0027] The reason for providing the upper pre-stressing flexible ring 32 and the lower pre-stressing flexible ring 42 made of silicone is that, before the upper sealing system 5 and the lower sealing system 7 clamp the cloth, the upper pre-stressing flexible ring 33 and the lower pre-stressing flexible ring 43 clamp the cloth. As the pressurizing system 2 continues to move downward, the upper pre-stressing flexible ring 32 and the lower pre-stressing flexible ring 42 are deformed accordingly, so that the cloth is always stretched when the upper coating system 6 and the lower coating system 8 apply butter, so as to position the cloth and prevent the butter from being skewed. On the other hand, after the pressurizing system 2 passes water, the cloth will bulge and deform upwards, and the upper pre-stressing flexible ring 32 and the lower pre-stressing flexible ring 42 push the upper pre-stressing ring 33 and the lower pre-stressing flexible ring 43 respectively to clamp the cloth, thereby playing the role of pulling the cloth.

[0028] Specifically, the upper coating system 6 includes an upper coating plug, which can be slidably installed on the upper sealing system 5. The upper coating plug has an upper coating opening, and the top of the upper coating plug has a rounded corner. When the upper coating plug encounters a position where the cloth is thicker, more butter will be applied at the step position formed by the cloth to ensure the sealing effect. The upper sealing system 5 is provided with an upper oil supply pipe connected to the upper coating plug. When the upper oil supply pipe supplies oil, the butter pushes the upper coating plug out of the upper coating opening and then contacts the cloth to apply butter.

[0029] Specifically, the lower smearing system 8 includes a lower smearing plug, which can be slidably installed on the lower sealing system 7. The lower smearing plug has a lower smearing opening. The top of the lower smearing plug has a rounded corner. When the lower smearing plug encounters a position where the cloth is thicker, more butter will be spread at the step position formed by the cloth to ensure the sealing effect. The lower sealing system 7 is provided with a lower oil supply pipe connected to the lower smearing plug. When the lower oil supply pipe supplies oil, the butter pushes the lower smearing plug to extend out of the lower smearing opening and then contact the cloth to spread the butter. In order to facilitate the simultaneous supply of butter to the upper smearing plug and the lower smearing plug, the upper oil supply pipe and the lower oil supply pipe are connected to the same butter filling gun, which is a commercially available butter filling gun and will not be described here.

[0030] Specifically, the upper sealing system 5 is an upper sealing rubber ring, which is installed on the bottom of the pressure ring 23 by screw locking, and the lower sealing system 7 is a lower sealing rubber ring, which is locked on the top of the frame 1 by screws. The upper sealing system 5 and the lower sealing system 7 clamp the cloth to achieve the sealing of the cloth, which is convenient for testing after water is passed through the water pressure system 91.
