Description

Technical Field

[0001] This invention belongs to the field of sealing strip performance testing technology, specifically, it relates to a performance testing device and method for container sealing strips. Background Technology

[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, it is essential to conduct rigorous performance testing on container sealing strips. Currently, traditional sealing strip performance testing includes tensile testing, which mainly involves manually operating clamps to fix the sealing strip and controlling the stretching process, and reading the tensile force and elongation data. In practical applications, containers often face the test of different temperature environments, so the performance testing of sealing strips under high and low temperature environments is particularly important.

[0003] However, existing sealing strip testing devices for high and low temperature environments require operators to put their hands into the high or low temperature environment when clamping the sealing strip, which is inconvenient and poses a risk of burns and frostbite. Meanwhile, components such as cylinders commonly used in automatic clamping are prone to accelerated aging in frequently changing temperature environments, increasing equipment maintenance costs and difficulty, and affecting the conduct of testing work and the lifespan of the equipment.

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

[0005] To address the problems of existing sealing strip testing devices operating in high and low temperature environments, where operators must insert their hands into the high or low temperature environment during sealing strip clamping, resulting in inconvenience and risks of burns and frostbite, and the accelerated aging of components such as cylinders commonly used in automatic clamping under frequently changing temperature environments, leading to increased equipment maintenance costs and difficulties, and affecting the conduct of testing and the lifespan of the equipment, the basic concept of the technical solution adopted in this invention is as follows:

[0006] A performance testing device for container sealing strips includes a container body and a tensile testing assembly. An electric slide rail is installed in the container body, and a slider is slidably mounted 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 testing assembly. The tensile testing assembly includes a base plate, a first support seat, and a second support seat. The first support seat is mounted on the base plate, and a lead screw sleeve is slidably mounted on the base plate. A detection module is mounted on the lead screw sleeve, and a second support seat is connected to the detection module. Clamping assemblies are installed in both the first and second support seats. A guide rod is installed in the container body, and a sliding plate is slidably mounted 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. Three baffles for limiting the movement distance of the sliding plate are installed inside the container body.

[0007] In 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 housing, a connecting plate is installed between the first support seat and the support plate, a lead screw shaft is rotatably installed in the support plate and the housing, a lead screw sleeve is engaged on the lead screw shaft, a sliding groove is provided at the bottom of the lead screw sleeve, a slide rail adapted to the sliding groove is provided on the base plate, a motor is connected to the end of the lead screw shaft, the motor is installed in the housing, and the housing is made of heat-insulating material.

[0008] In a preferred embodiment of the present invention, the clamping assembly includes a rotating shaft, a rotating shaft, a rotating rod, and a clamping plate. The two sets of clamping assemblies are respectively installed in the first support base and the second support base. A driving gear and a driven gear are rotatably mounted on the rotating shaft and the rotating shaft, respectively. A rotating rod is connected to both the driving gear and the driven gear. The clamping plate is installed on the rotating rod. A lever is connected to the driving gear. A torsion spring is sleeved on the rotating shaft.

[0009] In 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 or the second support.

[0010] In a preferred embodiment of the present invention, a maintenance plate is installed on the housing, a rotating door is provided on the maintenance plate, a rotating shaft is provided between the rotating door and the maintenance plate, and a magnet is installed on the rotating door.

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

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

[0013] In a preferred embodiment of the present invention, both connecting rods penetrate 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 housing.

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

[0015] The performance testing method for 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 chamber. During the movement, the rotating door automatically opens around the pivot under the push of the push rod.

[0017] S2: After the tensile test assembly is removed from the chamber, the clamping assembly automatically opens, placing the sealing strip on the first support, the second support, and the support plate;

[0018] S3: The tensile test assembly is moved back into the chamber by the controller. During this process, the clamping assembly and the sliding plate work together to achieve automatic clamping.

[0019] S4: Once the tensile test assembly is fully inside the chamber, the push rod no longer supports the rotating door, and the rotating door closes automatically without shaking due to gravity and magnets.

[0020] S5: Connect the heating and cooling equipment to the cabinet through the connection holes on the cabinet, and set the temperature inside the cabinet through the heating and cooling equipment and the temperature sensor installed in the cabinet;

[0021] S6: The motor is started by the controller, and the motor drives the lead screw shaft to rotate, so that the lead screw sleeve moves along the slide rail. The second support seat moves synchronously with the detection module. The second support seat clamps one end of the sealing strip and generates a pulling force on the sealing strip. The detection module monitors the pulling force on the sealing strip in real time, converts the mechanical signal into an electrical signal, processes it, and transmits it to the controller to calculate the tensile strength and measure the elongation of the sealing strip. The detection situation can be observed through the rotating door.

[0022] S7: After the test is completed, control the tensile test component to move horizontally out of the chamber again. After it is moved out, the clamping component will open automatically, and the staff can directly take out the tested sealing strip. The sliding plate can automatically seal the chamber to prevent the temperature inside the chamber from being lost when replacing other sealing strips that need to be tested or when observing, measuring and recording the tested sealing strips.

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

[0024] This invention utilizes a linkage mechanism to automatically move the tensile testing components in and out, automatically operate the clamping components, and automatically open and close the rotating door. The entire process requires no manual contact with high or low temperature environments, ensuring operational safety. The sliding plate, under the action of a spring, automatically seals the chamber opening when it moves out. Combined with the chamber's closed structure, this prevents temperature loss caused by prolonged opening. The integration of heating and cooling equipment with temperature sensors ensures a stable testing environment. Simultaneously, the clamping components are unaffected by temperature, reducing equipment failure rates, minimizing maintenance costs, and improving the efficiency and reliability of sealing strip performance testing.

[0025] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0035] To make the objectives, 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 with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0036] like Figures 1 to 7As shown, a performance testing device for container sealing strips includes a container body 1 and a tensile testing assembly 6. An electric slide rail 3 is installed in the container body 1, and 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 testing assembly 6. The tensile testing 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, and a lead screw sleeve 69 is slidably installed on the base plate 61. A detection module 612 is installed on the lead screw sleeve 69, and a second support seat 63 is connected to the detection module 612. Clamping assemblies 7 are installed in both the first support seat 62 and the second support seat 63. A guide rod 13 is installed in the container body 1, and 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. Three baffles 12 for limiting the movement distance of the sliding plate 15 are installed inside the container body 1. In this setup, housing 1 provides the mounting base for components such as electric slide rail 3 and guide rod 13, and forms a closed testing space. Electric slide rail 3 cooperates with slider 4, and slider 4 slides under the command of controller 2. It drives tensile test assembly 6 to move horizontally through connecting rod 5. On the base plate 61 of tensile test assembly 6, first support seat 62 and second support seat 63 are used to fix the sealing strip. Screw sleeve 69 is connected to detection module 612, which can monitor the force on the sealing strip during tension. Guide rod 13, spring 14 and sliding plate 15 work together. Spring 14 pushes sliding plate 15 to always fit against tensile test assembly 6. Sliding plate 15 triggers clamping assembly 7 when the assembly moves. Baffle 12 limits the range of movement of sliding plate 15 to ensure that clamping assembly 7 achieves clamping function.

[0037] like Figures 1 to 7 As shown, in a specific embodiment, the base plate 61 is equipped with a first support seat 62, a second support seat 63, a support plate 64, and a housing 67. A connecting plate 65 is installed between the first support seat 62 and the support plate 64. A lead screw shaft 66 is rotatably installed in the support plate 64 and the housing 67. A lead screw sleeve 69 is engaged on the lead screw shaft 66. A sliding groove 610 is provided at the bottom of the lead screw sleeve 69. A slide rail 611 adapted to the sliding groove 610 is provided on the base plate 61. A motor 68 is connected to the end of the lead screw shaft 66. The motor 68 is installed in the housing 67, which is made of heat-insulating material. In this setup, in the tensile test assembly 6, the support plate 64 and connecting plate 65 on the base plate 61 and the housing 67 form a stable frame structure. The lead screw shaft 66 rotates within the support plate 64 and the housing 67, engaging with the lead screw sleeve 69 for transmission. The slide groove 610 at the bottom of the lead screw sleeve 69 cooperates with the slide rail 611 on the base plate 61 to convert the rotational motion of the lead screw shaft 66 into the linear motion of the lead 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 inside the heat-insulated housing 67 to provide power for the entire tensile process while reducing the influence of the temperature inside the chamber.

[0038] like Figures 1 to 7 As shown, the clamping assembly 7 further includes a rotating shaft 71, a rotating shaft 72, a rotating rod 75, and a clamping plate 76. The two clamping assemblies 7 are respectively installed in the first support 62 and the second support 63. A driving gear 73 and a driven gear 74 are rotatably mounted on the rotating shaft 71 and the rotating shaft 72, respectively. A rotating rod 75 is connected to both the driving gear 73 and the driven gear 74. The clamping plate 76 is installed on the rotating rod 75. A lever 77 is connected to the driving gear 73. A torsion spring 78 is sleeved on the rotating shaft 71. In this configuration, the rotating shaft 71 and the rotating shaft 72 support the rotation of the driving gear 73 and the driven gear 74. 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, which in turn drives the rotating rod 75, so that the clamping plate 76 can clamp or loosen the sealing strip. The torsion spring 78 provides a reset elastic force for the clamping assembly 7, ensuring that the clamping plate 76 automatically loosens when no external force is applied, which facilitates the installation and removal of the sealing strip.

[0039] like Figures 1 to 7 As shown, one end of the torsion spring 78 is connected to the driven gear 74, and the other end is connected to the first support 62 or the second support 63. In this configuration, 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, causing the clamping plate 76 to loosen 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, furthermore, a maintenance plate 8 is installed on the housing 1, and a rotating door 9 is provided on the maintenance plate 8. A rotating shaft 11 is provided between the rotating door 9 and the maintenance plate 8, and a magnet 10 is installed on the rotating door 9. In this configuration, the maintenance plate 8 is installed on the housing 1, which not only facilitates the maintenance and repair of the device, but also provides a mounting point for the rotating door 9. The rotating door 9 rotates around the rotating shaft 11 to open and close. When open, it is convenient to operate the sealing strip. When closed, it is attracted to the maintenance plate 8 by the magnet 10 to ensure the airtightness of the housing 1.

[0041] like Figures 1 to 7 As shown, a push rod 16 for triggering the opening and closing of the rotating door 9 is further installed on the top of the housing 67. The push rod 16 is T-shaped. In this configuration, 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 rotating shaft 11 when the tensile test assembly 6 is moved out of or into the chamber 1, thereby realizing the 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 the length and width of the rotating door 9, which is made of transparent material. In this setup, the sliding plate 15 is larger than the rotating door 9, so that after the tensile test assembly 6 is removed from the chamber 1, it can completely seal the opening to prevent heat 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 transparent material, allowing staff to observe the test.

[0043] like Figures 1 to 7 As shown, both connecting rods 5 penetrate 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 configuration, the connecting rods 5 penetrate the sliding plate 15 and connect the connecting plate 65 and the housing 67, ensuring the structural stability of the tensile test assembly 6 when it moves, while also allowing the sliding plate 15 to move synchronously with the tensile test assembly 6, thus achieving functions such as triggering the clamping assembly 7 and sealing the opening of the housing 1.

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

[0045] This invention also discloses a performance testing method for container sealing strips, the steps of which are as follows:

[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 automatically opens around the rotating shaft 11 under the push of the push rod 16.

[0047] S2: After the tensile test assembly 6 is removed from the housing 1, the clamping assembly 7 automatically opens and places the sealing strip on the first support 62, the second support 63 and the support plate 64;

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

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

[0050] S5: Connect the heating and cooling equipment to the cabinet 1 through the connection hole 18 on the cabinet 1, and set the temperature inside the cabinet 1 through the heating and cooling equipment and the temperature sensor 17 installed in the cabinet 1.

[0051] S6: The controller 2 starts the motor 68, which drives the lead screw shaft 66 to rotate, thereby causing the lead screw sleeve 69 to move along the slide rail 611. The second support seat 63 moves synchronously with the detection module 612. The second support seat 63 clamps one end of the sealing strip and generates a pulling force on the sealing strip. The detection module 612 monitors the pulling 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 to calculate the tensile strength and measure the elongation of the sealing strip. The detection situation can be observed through the rotating door 9.

[0052] S7: After the test is completed, the tensile test component 6 is moved horizontally out of the chamber 1 again. After it is moved out, the clamping component 7 opens automatically, and the staff can directly take out the tested sealing strip. The sliding plate 15 can automatically seal the chamber 1 to prevent the temperature inside the chamber 1 from being lost when replacing other sealing strips that need to be tested and when observing, measuring and recording the tested sealing strips.

[0053] The implementation principle of the performance testing equipment and method for container sealing strips in this embodiment is as follows: In the initial state, the tensile test components 6 are all present in the container body 1. The rotating door 9 is attracted to the inspection plate 8 by the magnet 10. The sliding plate 15 is attached to the baffle 12. The tensile test components 6 abut 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 components 6 connected to the end of the connecting rod 5 to move horizontally outward. The push rod 16 installed on the tensile test components 6 will first touch the rotating door 9, so that the rotating door 9 rotates around the rotating shaft 11. 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 adheres to the tensile test components. 6. Once the sliding plate 15 is against the inner side of the inspection plate 8, the sliding plate 15 will no longer move. At this time, the tensile test assembly 6 has moved outside the housing 1. The slider 4 continues to move, and the tensile test assembly 6 will detach from the sliding plate 15 and no longer be against it. At this time, the clamping assembly 7 is released. 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, causing the rotating rod 75 on the driving gear 73 and the driven gear 74 to rotate, thereby opening the clamping plate 76. During this process, the lever 77 resets. At this time, 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, and the first support seat 62 and the second support seat 63 open. The support plate 64 supports the sealing strip. After placement, the slider 4 slides on the electric slide rail 3, moving the tensile test assembly 6 into the housing 1. Since the spring 14 always pushes the sliding plate 15 to adhere to the inspection plate 8, when the lever 77 on the clamping assembly 7 touches the sliding plate 15, the lever 77 drives the drive gear 73 to rotate. The drive 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 clamping plate 76 to clamp the sealing strip. After the clamping plate 76 is clamped, the lever 77 stops rotating. At this time, the slider 4 continues to move, causing the tensile test assembly 6 to push the sliding plate 15 against the force of the spring 14, causing the sliding plate 15 to slide on the guide rod 13. When the sliding plate 15 adheres to the baffle... After the sliding plate 15 stops moving, the tensile test assembly 6 also stops moving, and the sealing strip is clamped by the clamping assembly 7. During the movement of the tensile test assembly 6, the push rod 16 moves synchronously into the chamber 1. During the movement of the push rod 16, 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. Under the action of the magnet 10, the rotating door 9 is ensured not to shake arbitrarily. At this time, the external heating and cooling equipment is connected through the connection hole 18 to change the temperature of the chamber 1. The temperature sensor 17 installed in the chamber 1 is constantly detecting the temperature in the chamber 1. During detection, the motor 68 in the housing 67 drives the lead screw shaft 66 to rotate in the housing 67 and the support plate 64.Because the bottom of the lead screw sleeve 69 has a sliding groove 610, which works in conjunction with the slide rail 611 on the base plate 61, the lead screw sleeve 69 moves along the slide rail 611, thereby driving the detection module 612 and the clamping assembly 7 in the second support 63 to move, causing the sealing strip to be stretched. During this process, the detection module 612 monitors the sealing strip and transmits the data to the controller 2. This detection part is prior art and will not be described in detail here.

7. The performance testing equipment for container sealing strips according to claim 1, characterized in that, Both connecting rods (5) pass through the sliding plate (15), and the two connecting rods (5) are respectively connected to the side wall of the connecting plate (65) and the side wall of the housing (67).

8. The performance testing equipment for container sealing strips according to claim 1, characterized in that, A temperature sensor (17) is installed in the box (1), and a connection hole (18) for connecting external heating and cooling equipment is opened on the side wall of the box (1). A controller (2) is provided on the top of the box (1).

9. A performance testing method for container sealing strips, characterized in that, The performance testing equipment for a container sealing strip according to any one of claims 1-8, and the performance testing method for the container sealing strip, comprises the following steps: S1: The slider (4) is controlled by the controller (2) 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) by the push rod (16). S2: After the tensile test assembly (6) is removed from 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); S3: The tensile test assembly (6) is moved back into the box (1) by the controller (2). During this process, the clamping assembly (7) works with the sliding plate (15) to achieve automatic clamping. S4: When the tensile test assembly (6) is fully inserted into the chamber (1), the push rod (16) no longer supports the rotating door (9), and the rotating door (9) is automatically closed without shaking by gravity and the magnet (10); S5: Connect the heating and cooling equipment to the box (1) through the connection hole (18) on the box (1), and set the temperature inside the box (1) through the heating and cooling equipment and the temperature sensor (17) installed in the box (1); S6: Start the motor (68) through the controller (2). The motor (68) drives the lead screw shaft (66) to rotate, thereby causing the lead screw sleeve (69) to move along the slide rail (611). The second support seat (63) moves synchronously with the detection module (612). The second support seat (63) clamps one end of the sealing strip and generates a pulling force on the sealing strip. The detection module (612) monitors the pulling 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) to calculate the tensile strength and measure the elongation of the sealing strip. The detection situation can be observed through the rotating door (9). S7: After the test is completed, control the tensile test component (6) to move horizontally out of the box (1). After it is moved out, the clamping component (7) will open automatically, and the staff can directly take out the sealing strip that has been tested. The sliding plate (15) can automatically seal the box (1) to avoid the loss of temperature inside the box (1) when replacing other sealing strips that need to be tested and when observing, measuring and recording the sealing strips that have been tested.
