Description

Technical Field

[0001] This utility model relates to the field of container sealing strip technology, specifically to a container sealing strip sealing performance testing device. Background Technology

[0002] Container sealing strips are components used to seal the doors of shipping containers. They are usually made of EPDM rubber and have good weather resistance, corrosion resistance and thermal conductivity. They are mainly composed of H-shaped, T-shaped and fan-shaped hollow structures, with H-shaped sealing strips being the most common.

[0003] Common H-shaped sealing strips form a double sealing interface through symmetrical protrusions on the top and bottom. During testing, it is necessary to simulate its compression state in actual use (such as the compression amount when the container door is closed) and apply a certain pressure of water or air to observe whether leakage occurs.

[0004] The symmetrical protrusions on the top and bottom can create gaps when clamping the I-shaped sealing strip. When simulating the compression state of the sealing strip in actual use, water or air is added. The air or water to be tested will leak from the gap between the two clamps, which will affect the accuracy of the test. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a container sealing strip sealing performance testing device to reduce leakage of air or water from the gap between the two clamps during sealing strip sealing performance testing, thereby improving testing accuracy.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a container sealing strip sealing performance testing device, including a fixed frame, with first grooves on both sides of the fixed frame, a drive motor fixedly connected to the upper end of one of the first grooves, a bidirectional screw fixedly connected to the output end of the drive motor, a clamping plate threaded to both sides of the bidirectional screw, a slot on the opposite side of the two clamping plates, an adjusting rod threadedly connected to the clamping plate on the slot side, a pressure plate rotatably connected to one end of the adjusting rod, a pad glued to one side of the pressure plate, a clamping plate contacting one end of the pad, a liquid guiding hole on the clamping plate on the bottom side, a first connecting cylinder fixedly connected to one end of the clamping plate, a second connecting cylinder threadedly connected to the first connecting cylinder, a metal hose fixedly connected to one end of the second connecting cylinder, a water pump fixedly connected to one end of the metal hose, a connecting frame fixedly connected to one end of the water pump, the connecting frame fixedly connected to one side of the fixed frame, a liquid cylinder provided on the air inlet side of the water pump, an industrial camera fixedly connected to the side of the fixed frame away from the connecting frame, and a first distance sensor fixedly connected to the clamping plate on the bottom side.

[0007] As a preferred technical solution of this utility model, a contact ring is rotatably connected inside the second connecting cylinder via a bearing, and a sealing ring gasket is fixedly connected to the side of the contact ring near the clamping plate, and the sealing ring gasket is in contact with the contact ring.

[0008] As a preferred technical solution of this utility model, a measuring plate is fixedly connected to one upper side of the clamping plate located on the bottom side by adhesive, and a second distance sensor is provided on the bottom side of the measuring plate. The second distance sensor is fixedly connected to one upper side of the bottom pressure plate.

[0009] As a preferred technical solution of this utility model, two auxiliary rods are movably inserted into the side of the card plate near the connecting frame, and the auxiliary rods are fixedly connected to the clamp plate.

[0010] As a preferred technical solution of this utility model, a valve is fixedly connected to the connecting frame, one end of the valve is fixedly connected to the liquid cylinder, and the other end of the valve is fixedly connected to the water inlet of the water pump.

[0011] This utility model has the following advantages:

[0012] (1) The drive motor drives the bidirectional screw to rotate, so that the two side clamps move relative to each other to clamp the H-shaped sealing strip. The clamps of different thicknesses can be quickly disassembled and replaced to adapt to the waist position of different H-shaped sealing strips. The first connecting cylinder at one end of the clamp is connected to the second connecting cylinder to the metal hose and the water pump. The sealing ring gasket on the contact ring inside the second connecting cylinder contacts the clamp, which enhances the sealing of the clamping part, reduces leakage, and makes the water flow applied during the test more accurately act on the sealing strip, thus improving the accuracy of the test.

[0013] (2) The clamping and compression of the two clamping plates and the deformation distance of the I-shaped sealing strip are detected by the first distance sensor and the second distance sensor, thereby simulating the compression of the sealing strip in actual use, providing more realistic conditions for detecting the sealing performance of the sealing strip, and helping to accurately evaluate the performance of the sealing strip.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Please refer to the following: Figure 1-5 The container sealing strip sealing performance testing device shown includes a fixed frame 1. First grooves are formed on both sides of the fixed frame 1. A drive motor is fixedly connected to the upper end of one of the first grooves. A bidirectional screw 2 is fixedly connected to the output end of the drive motor. Both sides of the bidirectional screw 2 are threadedly connected to clamping plates 3. A slot 4 is formed on one opposite side of each clamping plate 3. An adjusting rod 5 is threadedly connected to one side of the clamping plate 3 in the slot 4. A pressure plate 6 is rotatably connected to one end of the adjusting rod 5. A pad made of rubber is glued to one side of the pressure plate 6. One end of the pad contacts a clamping plate 7. A liquid guiding hole 8 is formed on the clamping plate 7 located on the bottom side. A first connecting cylinder 9 is fixedly connected to one end of the clamping plate 7. A second connecting cylinder 10 is threadedly connected to the first connecting cylinder 9. A metal... The hose 11 is a metal hose, and a water pump 12 is fixedly connected to one end of the hose. The water pump 12 is essentially a gear pump. By adjusting the speed of the gear or by using a variable gear pump, pressure regulation within a certain range can be achieved. It has good self-priming capability and can ensure stable delivery of the detection liquid. A connecting frame 13 is fixedly connected to one end of the water pump 12. The connecting frame 13 is fixedly connected to one side of the fixed frame 1. A liquid cylinder 14 is provided on one side of the air inlet of the water pump 12. An industrial camera 16 is fixedly connected to the side of the fixed frame 1 away from the connecting frame 13. The industrial camera 16 is connected in series with a display screen via wires. The display screen is located on one side of the fixed frame 1. A first distance sensor 15 is fixedly connected to the bottom plate 3. The detection length of the first distance sensor 15 corresponds to the distance between the two plates 3.

[0022] First, the actual compression of the I-beam sealing strip used at the container door is used as the calibration value. Then, based on manual measurement or the initial data of the container sealing strip, a clamping plate 7 of appropriate thickness is replaced. The liquid guide hole 8 on the bottom clamping plate 7 is blocked by the waist of the I-beam sealing strip. At this point, the detection point is at the center of the clamping plate 7, which avoids leakage of the liquid to be tested from the gaps in the clamps, thus preventing issues with detection accuracy. The clamping plate 7 is moved within the slot 4 by rotating the adjusting rod 5, and the slot 4 clamps the clamping plate 7. The drive motor located on the upper side of the fixed frame 1 is then activated, driving the bidirectional screw 2 to rotate. The system moves the two opposing clamping plates 7 relative to each other. The first distance sensor 15 monitors the distance between the two clamping plates 7 and then subtracts the distance the two clamping plates 7 extend out of the slot 4. At this point, the gap between the two clamping plates 7 can be determined, simulating the compression amount of the container sealing strip during actual use. Then, the water pump 12 draws colored liquid from the liquid cylinder 14 and sends it through the metal hose 11, the second connecting cylinder 10, the first connecting cylinder 9, and the liquid guide hole 8 to contact the waist position of the I-shaped sealing strip. During the detection process, the industrial camera 16 can provide monitoring. When the industrial camera 16 detects liquid leakage, it proves that the sealing strip has a problem with its sealing performance.

[0023] The second connecting cylinder 10 is rotatably connected to a contact ring 17 via a bearing. A sealing ring gasket is fixedly connected to the side of the contact ring 17 near the clamping plate 7, and the sealing ring gasket is in contact with the contact ring 17.

[0024] By setting a contact ring 17, after disassembling and assembling clamps 7 of different thicknesses, the first connecting cylinder 9 and the second connecting cylinder 10 are threadedly connected. Then, when the first connecting cylinder 9 contacts the sealing ring gasket, the contact ring 17 and the sealing ring gasket rotate under the action of the bearing, which facilitates the tight connection between the first connecting cylinder 9 and the second connecting cylinder 10.

[0025] Among them, a measuring plate 20 is fixedly connected to one side of the upper end of the clamping plate 7 located on the bottom side by adhesive. The thickness of the measuring plate 20 is 0.5cm. A second distance sensor 19 is provided on the bottom side of the measuring plate 20. The second distance sensor 19 is fixedly connected to one side of the upper end of the bottom pressure plate 6.

[0026] The measuring plate 20 is bonded to the side of the bottom clamping plate 7 away from the slot 4. At this time, the distance extended by the clamping plate 7 can be directly monitored by the second distance sensor 19. At the same time, the first distance sensor 15 can cooperate with the second distance sensor 19 to facilitate the calculation of the compression amount of the container I-shaped sealing strip, which facilitates the rapid detection of the container sealing strip.

[0027] Among them, two auxiliary rods 18 are movably inserted into the side of the card plate 3 near the connecting frame 13, and the auxiliary rods 18 are fixedly connected to the clamp plate 7.

[0028] By setting an auxiliary rod 18 on the pressure plate 6, which works in conjunction with the slot 4, a stable limit can be provided for the clamping plate 7. Then, by manually rotating the adjusting rod 5, the pressure plate 6 and the pad can be moved stably within the slot 4.

[0029] Among them, a valve 21 is fixedly connected to the connecting frame 13. One end of the valve 21 is fixedly connected to the liquid cylinder 14. A check chamber can be set on one side of the liquid cylinder 14. The check chamber includes a check valve structure. Liquid can be set inside the liquid cylinder 14 to facilitate observation and identification by the industrial camera 16. The other end of the valve 21 is fixedly connected to the water inlet of the water pump 12.

[0030] One end of valve 21 is threadedly connected to liquid cylinder 14 via a pipe fitting, while the other end of valve 21 is fixedly connected to the inlet of water pump 12. Valve 21 consists of a valve plate, a cylinder, and a drive motor. The drive motor drives the valve plate to rotate inside the cylinder, thereby opening and closing valve 21. As a result, water pump 12 draws colored liquid from liquid cylinder 14. At this time, gas enters the check chamber to facilitate liquid extraction.

[0031] Working principle: First, the H-shaped sealing strip is clamped by the relatively movable and replaceable clamping plate 7. Then, the waist position of the sealing strip blocks the liquid guide hole 8 of the bottom clamping plate 7. Next, the water pump 12 draws liquid from the liquid cylinder 14. The liquid passes through the metal hose 11, the second connecting cylinder 10, the first connecting cylinder 9 and the liquid guide hole 8 to contact the waist position of the H-shaped sealing strip. At this time, the industrial camera 16 is used for monitoring. With the help of the display screen on one side of the fixed frame 1, the detection process of the sealing strip can be displayed intuitively, and the detection efficiency can be improved.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0033] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
