Description

Technical Field

[0001] The invention belongs to the technical field of sealing strip performance testing, and in particular relates to a performance testing device and method for container sealing strips. Background Art

[0002] As an important carrier of modern logistics and transportation, the sealing performance of containers is directly related to the safety and integrity of cargo transportation. Therefore, strict performance testing of container sealing strips is crucial. At present, traditional sealing strip performance testing includes tensile testing, which mainly uses manual operation of fixtures to fix the sealing strips, control the stretching process, and read the tension and elongation data. In actual applications, containers are often faced with the test of different temperature environments. Therefore, performance testing of sealing strips in high and low temperature environments is particularly important.

[0003] However, when clamping the sealing strips in the existing high and low temperature environments, the operator needs to put his hands into the high temperature or low temperature environment, which is inconvenient to operate and there is a risk of burns and frostbite. The components such as cylinders commonly used in automatic clamping are prone to accelerated aging in frequently changing temperature environments. The equipment maintenance cost and maintenance difficulty affect the detection work and equipment life.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] In order to solve the problems of existing sealing strip detection devices in high and low temperature environments, when clamping the sealing strips, the operator needs to put his hands into the high or low temperature environment, which is inconvenient to operate and poses the risk of burns and frostbite. In addition, the components such as cylinders commonly used in automatic clamping are prone to accelerated aging in frequently changing temperature environments, which increases the equipment maintenance cost and difficulty, affecting the detection work and equipment life. The basic concept of the technical solution adopted by the present invention is:

[0006] A performance testing device for a container sealing strip comprises a box body and a tensile test assembly, an electric slide rail is installed in the box body, a slider is slidably installed on the electric slide rail, a connecting rod is connected to the side wall of the slider, and the end of the connecting rod is connected to the tensile test assembly, the tensile test assembly comprises a base plate, a first support seat and a second support seat, the first support seat is installed on the base plate, a screw sleeve is slidably installed on the base plate, a detection module is installed on the screw sleeve, and the detection module is connected to the second support seat, a clamping assembly is installed in the first support seat and the second support seat, a guide rod is installed in the box body, a sliding plate is slidably installed on the guide rod, a spring and a sliding plate for triggering the clamping assembly to clamp or release are installed on the guide rod, and three baffles for limiting the moving distance of the sliding plate are installed in the box body.

[0007] As a preferred embodiment of the present invention, the base plate is equipped with a first support seat, a second support seat, a support plate and a shell, a connecting plate is installed between the first support seat and the support plate, a screw shaft is rotatably installed in the support plate and the shell, a screw sleeve is engaged with the screw shaft, a slide groove is provided at the bottom of the screw sleeve, a slide rail adapted to the slide groove is provided on the base plate, the end of the screw shaft is connected to a motor, the motor is installed in the shell, and the shell is made of heat-insulating material.

[0008] As a preferred embodiment of the present invention, the clamping assembly includes a rotating shaft, a rotating shaft, a rotating rod and a splint, and two groups of the clamping assemblies are respectively installed in the first support seat and the second support seat, and the driving gear and the driven gear are respectively rotatably installed on the rotating shaft and the rotating shaft, and the driving gear and the driven gear are both connected to the rotating rod, and the splint is installed on the rotating rod, and the driving gear is connected to the shift rod, and the rotating shaft is sleeved with a torsion spring.

[0009] As a preferred embodiment of the present invention, one end of the torsion spring is connected to the driven gear, and the other end is connected to the first support seat or the second support seat.

[0010] As a preferred embodiment of the present invention, an access panel is installed on the box body, a rotating door is provided on the access panel, a rotating shaft is provided between the rotating door and the access panel, and a magnet is installed on the rotating door.

[0011] As a preferred embodiment of the present invention, a push rod for triggering the opening and closing of the rotary door is installed on the top of the shell, and the push rod is T-shaped.

[0012] As a preferred embodiment of the present invention, the length and width of the sliding plate are greater than the length and width of the rotating door, and the rotating door is made of a transparent material.

[0013] As a preferred embodiment of the present invention, the two connecting rods both pass through the sliding plate, and the two connecting rods are respectively connected to the side wall of the connecting plate and the side wall of the shell.

[0014] As a preferred embodiment of the present invention, a temperature sensor is installed in the box, a connection hole for an external heating and cooling device is opened on the side wall of the box, and a controller is provided on the top of the box.

[0015] The performance testing method of a container sealing strip comprises the following steps:

[0016] S1: The controller controls the slider to move on the electric slide rail, thereby moving the tensile test assembly horizontally out of the box. During the movement, the rotating door automatically opens around the rotating axis under the push of the push rod;

[0017] S2: After the tensile test assembly is moved out of the box, the clamping assembly automatically opens and the sealing strip is placed on the first support seat, the second support seat and the support plate;

[0018] S3: The tensile test assembly is moved back into the box through the controller. During this process, the clamping assembly cooperates with the sliding plate to achieve automatic clamping;

[0021] S6: The motor is started by the controller, and the motor drives the screw shaft to rotate, so that the screw sleeve moves along the slide rail. The second support seat and the detection module move synchronously. The second support seat clamps one end of the sealing strip to generate tension on the sealing strip. The detection module monitors the tension on the sealing strip in real time, converts the mechanical signal into an electrical signal, and transmits it to the controller after processing. The tensile strength is calculated and the elongation of the sealing strip is measured. The detection status can be observed by rotating the door.

[0022] S7: After the test is completed, the tensile test assembly is controlled to be moved horizontally out of the box again. After being moved out, the clamping assembly automatically opens, and the staff can directly take out the tested sealing strip, and the sliding plate can automatically seal the box to avoid temperature loss inside the box when replacing other sealing strips that need to be tested and observing, measuring and recording the tested sealing strips.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The present invention realizes the automatic movement of the tensile test assembly, the automatic operation of the clamping assembly and the automatic opening and closing of the rotary door through a linkage mechanism. No manual contact with high and low temperature environments is required throughout the process, thereby ensuring safe operation. The sliding plate automatically blocks the box opening when moved out under the action of the spring, and cooperates with the closed structure of the box to prevent temperature loss caused by the box being open for a long time. Combined with the heating and cooling equipment and the temperature sensor for temperature control, a stable test environment is ensured. At the same time, the clamping assembly is not affected by temperature, thereby reducing the equipment failure rate, reducing maintenance costs, and improving the efficiency and reliability of sealing strip performance testing.

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0036] like Figures 1 to 7As shown, a performance testing device for a container sealing strip includes a box body 1 and a tensile test assembly 6, an electric slide rail 3 is installed in the box body 1, a slider 4 is slidably installed on the electric slide rail 3, a connecting rod 5 is connected to the side wall of the slider 4, and the end of the connecting rod 5 is connected to the tensile test assembly 6, the tensile test assembly 6 includes a base plate 61, a first support seat 62 and a second support seat 63, the first support seat 62 is installed on the base plate 61, a screw sleeve 69 is slidably installed on the base plate 61, a detection module 612 is installed on the screw sleeve 69, and the detection module 612 is connected to the second support seat 63, a clamping assembly 7 is installed in the first support seat 62 and the second support seat 63, a guide rod 13 is installed in the box body 1, a sliding plate 15 is slidably installed on the guide rod 13, a spring 14 and a sliding plate 15 for triggering the clamping assembly 7 to clamp or release are installed on the guide rod 13, and three baffles 12 for limiting the moving distance of the sliding plate 15 are installed in the box body 1. In this setting, the box 1 provides an installation base for the electric slide rail 3, the guide rod 13 and other components, and forms a closed test space. The electric slide rail 3 cooperates with the slider 4 to realize the sliding of the slider 4 under the instruction of the controller 2, and drives the tensile test assembly 6 to move horizontally through the connecting rod 5. On the bottom plate 61 of the tensile test assembly 6, the first support seat 62 and the second support seat 63 are used to fix the sealing strip. The screw sleeve 69 is connected to the detection module 612, which can monitor the stress condition of the sealing strip during stretching. The guide rod 13, the spring 14 and the sliding plate 15 work together. The spring 14 pushes the sliding plate 15 to always fit the tensile test assembly 6. The sliding plate 15 triggers the action of the clamping assembly 7 when the assembly moves, and the baffle 12 limits the moving range of the sliding plate 15 to ensure that the clamping assembly 7 realizes the clamping function.

[0037] like Figures 1 to 7 As shown, in a specific embodiment, the base plate 61 is installed with a first support seat 62, a second support seat 63, a support plate 64 and a shell 67, a connecting plate 65 is installed between the first support seat 62 and the support plate 64, a screw shaft 66 is rotatably installed in the support plate 64 and the shell 67, a screw sleeve 69 is engaged with the screw shaft 66, a slide groove 610 is provided at the bottom of the screw sleeve 69, a slide rail 611 adapted to the slide groove 610 is provided on the base plate 61, the end of the screw shaft 66 is connected to the motor 68, the motor 68 is installed in the shell 67, and the shell 67 is made of heat-insulating material. In this setting, in the tensile test assembly 6, the support plate 64, the connecting plate 65 and the shell 67 on the base plate 61 form a stable frame structure. The screw shaft 66 rotates in the support plate 64 and the shell 67, and engages with the screw sleeve 69 for transmission. The slide groove 610 at the bottom of the screw sleeve 69 cooperates with the slide rail 611 on the base plate 61 to convert the rotational motion of the screw shaft 66 into linear motion of the screw sleeve 69, driving the second support seat 63 and the detection module 612 to move to stretch the sealing strip. The motor 68 is installed in the heat-insulating shell 67 to provide power for the entire stretching process while reducing the impact of the temperature in the box.

[0038] like Figures 1 to 7 As shown, further, the clamping assembly 7 includes a rotating shaft 71, a rotating shaft 72, a rotating rod 75 and a clamping plate 76. The two sets of clamping assemblies 7 are respectively installed in the first support seat 62 and the second support seat 63. The driving gear 73 and the driven gear 74 are respectively rotatably installed on the rotating shaft 71 and the rotating shaft 72. The driving gear 73 and the driven gear 74 are both connected to the rotating rod 75. The clamping plate 76 is installed on the rotating rod 75. The driving gear 73 is connected to the shift rod 77. The rotating shaft 71 is sleeved with a torsion spring 78. In this arrangement, the rotating shaft 71 and the rotating shaft 72 support the rotation of the driving gear 73 and the driven gear 74, and the two transmit power through meshing. The lever 77 on the driving gear 73 contacts the sliding plate 15, triggering the driving gear 73 to rotate, and then driving the rotating rod 75 to make the clamping plate 76 clamp or loosen the sealing strip. The torsion spring 78 provides a reset elastic force for the clamping assembly 7 to ensure that the clamping plate 76 automatically loosens when there is no external force, making it convenient for loading and unloading the sealing strip.

[0039] like Figures 1 to 7 As shown, one end of a torsion spring 78 is connected to the driven gear 74, and the other end is connected to the first support base 62 or the second support base 63. In this arrangement, after the lever 77 loses the force of the sliding plate 15, the torsion spring 78, relying on the restoring force generated by its own elastic deformation, drives the driven gear 74 to rotate in the opposite direction, loosening the clamping plate 76 and completing the reset process of the clamping assembly 7, ensuring the convenience of replacing the sealing strip.

[0040] like Figures 1 to 7 As shown, further, an access panel 8 is installed on the box body 1, and a rotating door 9 is provided on the access panel 8. A rotating shaft 11 is provided between the rotating door 9 and the access panel 8, and a magnet 10 is installed on the rotating door 9. In this configuration, the access panel 8 is installed on the box body 1, which not only facilitates maintenance and repair of the device, but also provides a mounting fulcrum for the rotating door 9. The rotating door 9 rotates around the rotating shaft 11 to open and close, making it easier to operate the sealing strip when open. When closed, it is attracted to the access panel 8 through the magnet 10 to ensure the sealing of the box body 1.

[0041] like Figures 1 to 7 As shown, a T-shaped push rod 16 is mounted on the top of the housing 67 to trigger the opening and closing of the rotating door 9. In this arrangement, the T-shaped push rod 16 on the top of the housing 67 contacts the rotating door 9 and pushes it to rotate around the rotation axis 11 when the tensile test assembly 6 is moved out of or into the box 1, thereby achieving automatic opening and closing of the rotating door 9 without manual operation.

[0042] like Figures 1 to 7As shown, the length and width of the sliding plate 15 are greater than those of the rotating door 9, which is made of a transparent material. In this configuration, the sliding plate 15 is larger than the rotating door 9. After the tensile test assembly 6 is removed from the box 1, it can completely block the opening to prevent temperature loss. During its sliding process, it cooperates with the lever 77 of the clamping assembly 7 to control the movement of the clamping plate 76. The rotating door 9 is made of a transparent material, and the test results can be observed by personnel.

[0043] like Figures 1 to 7 As shown, further, both connecting rods 5 pass through the sliding plate 15 and are respectively connected to the side wall of the connecting plate 65 and the side wall of the housing 67. In this arrangement, the connecting rods 5 pass through the sliding plate 15 and connect the connecting plate 65 and the housing 67, ensuring the structural stability of the tensile test assembly 6 during movement. At the same time, the sliding plate 15 can move synchronously with the tensile test assembly 6 to achieve functions such as triggering the clamping assembly 7 and sealing the opening of the box body 1.

[0044] like Figures 1 to 7 As shown, a temperature sensor 17 is further installed in the box 1. A connection hole 18 for connecting an external heating and cooling device is provided on the side wall of the box 1. A controller 2 is provided on the top of the box 1. In this configuration, the temperature sensor 17 monitors the temperature inside the box 1 in real time and provides feedback to the controller 2. The controller 2 connects to the external heating and cooling device through the connection hole 18 to adjust the temperature inside the box to ensure that the test is conducted at the set temperature environment. The controller 2 controls the operation of components such as the electric slide 3 and the motor 68, and receives and processes data from the detection module 612.

[0045] The present invention also discloses a performance testing method for a container sealing strip, which comprises the following steps:

[0046] S1: The controller 2 controls the slider 4 to move on the electric slide rail 3, thereby moving the tensile test assembly 6 horizontally out of the box 1. During the movement, the rotating door 9 is automatically opened around the rotating shaft 11 under the push of the push rod 16;

[0047] S2: After the tensile test assembly 6 is moved out of the box 1, the clamping assembly 7 automatically opens and places the sealing strip on the first support seat 62, the second support seat 63 and the support plate 64;

[0048] S3: The tensile test assembly 6 is moved back into the box 1 through the controller 2. During this process, the clamping assembly 7 cooperates with the sliding plate 15 to achieve automatic clamping;

[0049] S4: When the tensile test assembly 6 is completely inserted into the box 1, the push rod 16 no longer supports the rotating door 9, and the rotating door 9 is automatically closed by gravity and the magnet 10 without shaking;

[0050] S5: Connect the heating and cooling device to the box 1 through the connection hole 18 provided on the box 1, and set the temperature inside the box 1 through the heating and cooling device and the temperature sensor 17 installed in the box 1;

[0051] S6: The motor 68 is started by the controller 2, and the motor 68 drives the screw shaft 66 to rotate, thereby causing the screw sleeve 69 to move along the slide rail 611. The second support seat 63 and the detection module 612 move synchronously. The second support seat 63 clamps one end of the sealing strip to generate a tensile force on the sealing strip. The detection module 612 monitors the tensile force on the sealing strip in real time, converts the mechanical signal into an electrical signal, and transmits it to the controller 2 after processing. The tensile strength is calculated and the elongation of the sealing strip is measured. The detection status can be observed by rotating the door 9.

[0052] S7: After the test is completed, the tensile test assembly 6 is controlled to move horizontally out of the box 1 again. After moving out, the clamping assembly 7 automatically opens, and the staff can directly take out the tested sealing strip, and the sliding plate 15 can automatically seal the box 1 to avoid temperature loss inside the box 1 when replacing other sealing strips that need to be tested and observing, measuring and recording the tested sealing strips.

[0053] The implementation principle of the performance testing equipment and method of the container sealing strip of this embodiment is as follows: in the initial state, the tensile test components 6 are all present in the box body 1, the rotating door 9 is adsorbed in the inspection plate 8 by the magnet 10, the sliding plate 15 is attached to the baffle 12, and the tensile test component 6 is against the sliding plate 15. The controller 2 controls the slider 4 to slide on the electric slide rail 3, so that the slider 4 drives the connecting rod 5 and the tensile test component 6 connected to the end of the connecting rod 5 to move horizontally outward. The push rod 16 installed on the tensile test component 6 will first touch the rotating door 9, causing the rotating door 9 to rotate around the rotating shaft 11, and during the movement of the slider 4, the spring 14 will push the sliding plate 15 to slide along the guide rod 13, so that the sliding plate 15 always fits the tensile test component. 6, until the sliding plate 15 fits inside the inspection plate 8, the sliding plate 15 will no longer move, and at this time the tensile test assembly 6 has moved outside the box body 1, at this time the slider 4 continues to move, the tensile test assembly 6 will be separated from the sliding plate 15 and no longer fit on the tensile test assembly 6, at this time the clamping assembly 7 is loosened, the clamping assembly 7 drives the driven gear 74 to rotate through the torsion spring 78, the driven gear 74 drives the driving gear 73 to rotate, so that the driving gear 73 and the rotating rod 75 on the driven gear 74 rotate, thereby opening the clamping plate 76, during this process the lever 77 is reset, and the sealing strip to be tested can be placed on the tensile test assembly 6, at this time the rotating door 9 is fully opened under the support of the push rod 16, the first support seat 62 and the second support seat 63 As well as the support plate 64 can play a supporting role for the sealing strip, after it is placed, the slider 4 slides on the electric slide rail 3, driving the tensile test assembly 6 to move into the box body 1. Since the spring 14 always pushes the sliding plate 15 to fit on the repair plate 8, when the lever 77 on the clamping assembly 7 touches the sliding plate 15, the lever 77 will drive the driving gear 73 to rotate, and the driving gear 73 drives the driven gear 74 to rotate, causing the torsion spring 78 to undergo elastic deformation. At this time, the rotating rod 75 drives the splint 76 to be clamped on the sealing strip. When the splint 76 is clamped, the lever 77 no longer rotates. At this time, the slider 4 continues to move, causing the tensile test assembly 6 to push the sliding plate 15 to resist the force of the spring 14 to make the sliding plate 15 slide on the guide rod 13. When the sliding plate 15 fits on the baffle After the push rod 16 is moved, the rotating door 9 rotates around the rotating shaft 11 under the action of gravity. When the push rod 16 no longer contacts the rotating door 9, the rotating door 9 is completely closed. The magnet 10 ensures that the rotating door 9 will not shake at will. At this time, an external heating and cooling device is connected through the connecting hole 18 to change the temperature of the box 1. The temperature in the box 1 is always detected by the temperature sensor 17 installed in the box 1. During the detection, the motor 68 in the shell 67 drives the screw shaft 66 to rotate in the shell 67 and the support plate 64.Because the bottom of the screw sleeve 69 is provided with a slide groove 610, which cooperates with the slide rail 611 on the bottom plate 61, the screw sleeve 69 moves along the slide rail 611, thereby driving the detection module 612 and the clamping assembly 7 in the second support seat 63 to move, so that the sealing strip is stretched. During this process, the detection module 612 monitors the sealing strip and transmits the data to the controller 2. This part of the detection is a prior art and will not be described in detail here.

During the movement, the rotating door (9) is automatically opened around the rotating shaft (11) under the push of the push rod (16); S2: After the tensile test assembly (6) is moved out of the box (1), the clamping assembly (7) automatically opens, and the sealing strip is placed on the first support seat (62), the second support seat (63) and the support plate (64); S3: The tensile test assembly (6) is moved back into the box (1) through the controller (2). During this process, the clamping assembly (7) cooperates with the sliding plate (15) to achieve automatic clamping; S4: When the tensile test assembly (6) completely enters the box (1), the push rod (16) no longer supports the rotating door (9), and the rotating door (9) is automatically closed without shaking due to gravity and the magnet (10); S5: Connect the heating and cooling device to the box (1) through the connection hole (18) provided on the box (1), and set the temperature inside the box (1) through the heating and cooling device and the temperature sensor (17) installed in the box (1); S6: The motor (68) is started by the controller (2), and the motor (68) drives the screw shaft (66) to rotate, thereby causing the screw sleeve (69) to move along the slide rail (611), and the second support seat (63) and the detection module (612) to move synchronously. The second support seat (63) clamps one end of the sealing strip to generate a tensile force on the sealing strip. The detection module (612) monitors the tensile force on the sealing strip in real time, converts the mechanical signal into an electrical signal, processes it, and transmits it to the controller (2), calculates the tensile strength, and measures the elongation of the sealing strip. The detection situation can be observed by rotating the door (9); S7: After the test is completed, the tensile test assembly (6) is controlled to be moved horizontally out of the box (1) again. After the movement, the clamping assembly (7) is automatically opened, and the staff can directly take out the tested sealing strip, and the sliding plate (15) can automatically seal the box (1) to avoid the temperature loss inside the box (1) when replacing other sealing strips that need to be tested and observing, measuring and recording the tested sealing strip.
