Description

Technical Field

[0001] This utility model relates to the technical field of glove sealing test equipment, specifically a sealing test equipment for the production of safety and environmental gloves. Background Technology

[0002] Sealing performance testing plays a crucial role in the production of safety and environmental gloves. In numerous work scenarios, such as chemical, medical, and food processing, gloves must effectively block harmful external substances or maintain a clean internal environment. Sealing performance testing can accurately determine whether gloves have defects such as micropores and cracks. If the gloves do not seal well, harmful substances may seep in, threatening the health and safety of users. In the chemical industry, this could lead to skin contact with corrosive substances; in the medical field, it could cause cross-infection. Furthermore, for industries requiring a sterile environment, such as food processing, insufficient sealing will compromise internal cleanliness and affect product quality.

[0003] The utility model disclosed in announcement number CN217765410U is an insulating glove sealing test device. The technical solution of this utility model can be activated by an electric telescopic rod to move the clamps on both sides. At this time, the glove can be clamped and fixed on the air supply pipe through the clamps. During clamping, the rubber pad and rubber sleeve can contact the inner and outer walls of the glove, thereby improving the sealing performance during clamping and avoiding air leakage during testing. The glove can be quickly installed for testing, and the good sealing performance will not affect the accuracy of testing due to air leakage, thus improving the testing efficiency.

[0004] While the aforementioned device can clamp and fix the glove to the gas supply pipe using clamps, the symmetrical arrangement of the two clamps causes them to move towards each other during clamping. This movement can easily deform the glove's end, creating gaps at the joint of the two clamps. This is especially problematic when the glove material is thick, preventing the ends of the two clamps from fitting together completely. The gaps can easily become wrinkled due to relative compression, making it difficult to ensure a tight seal. Furthermore, after testing, when the clamps move outward and the clamping force decreases to a certain extent, the glove may experience a significant thrust under higher air pressure, potentially causing it to fly directly off the gas supply pipe and interfering with the testing process. Therefore, to address these issues, a sealing performance testing device for safety and environmental gloves is proposed. Utility Model Content

[0005] To address the technical problems in comparative techniques where glove sealing testing equipment easily causes wrinkles due to relative compression when clamping and fixing gloves, making it difficult to ensure the sealing of the installation, and where gloves easily fly out due to high air pressure when disassembling them after testing, interfering with the testing process, this utility model provides a sealing testing device for safety and environmental glove production.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A sealing performance testing device for safety and environmental glove production includes a platform on which a work frame is fixedly mounted, and a hydraulic drive mechanism is installed on the work frame; a testing cylinder seat, which is mounted on the platform and is generally frustoconical in shape, and the glove end is fitted onto the testing cylinder seat during testing; and a clamping ring seat, which is installed at the bottom of the hydraulic drive mechanism and includes a ring seat body with a frustoconical groove corresponding to the testing cylinder seat; wherein the testing cylinder seat includes a support cylinder with a working chamber inside, and a sealed inflation pipe, an exhaust pipe and a pressure sensor are installed in the support cylinder, wherein the inflation pipe and the exhaust pipe are connected to the working chamber, and the pressure sensor detection head is located in the working chamber.

[0008] In one possible implementation, the support sleeve is fitted with a frustum-shaped rubber sleeve, and an annular rubber pad is attached to the frustum-shaped groove wall of the ring seat body.

[0009] In one possible implementation, the bottoms of both the inflation pipe and the exhaust pipe are bent and arranged horizontally in the pedestal, and the ends of both the inflation pipe and the exhaust pipe extend out of the pedestal, wherein the end of the inflation pipe is hermetically connected to an air pump located on one side of the pedestal.

[0010] In one possible implementation, both the inflation pipe and the exhaust pipe are equipped with solenoid valves at their bottoms, and the solenoid valves are bolted to the base.

[0011] In one possible implementation, the bottom of the pressure sensor is electrically connected to a working cable, which is bent horizontally at the bottom and extends out of the base.

[0012] In one possible implementation, a glove support frame is installed inside the working chamber to support the glove and keep it upright. The support frame is composed of several bent steel wires arranged in a circumferential array.

[0013] In one possible implementation, the work frame includes a first gantry fixedly mounted on a pedestal, with a second gantry mounted on top of it.

[0014] In one possible implementation, the hydraulic drive mechanism includes a hydraulic cylinder mounted on a second gantry, with a connecting plate fixedly connected to the rod end. A plurality of guide rods that are slidably connected to the first gantry are fixedly connected to the bottom of the connecting plate, and a pressure ring that is bolted to the ring seat body is fixedly connected to the bottom end of the guide rod.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] By pressing and fitting the detection cylinder seat and the clamping ring seat together, the end of the glove fitted on the detection cylinder seat is pressed and sealed. Since the detection cylinder seat is frustoconical and the clamping ring seat has a frustoconical groove, when the clamping ring seat is pressed onto the detection cylinder seat, it can simultaneously compress and fix various positions of the glove end over a large area without wrinkles, which can significantly improve the sealing performance of the glove installation and can be applied to the sealing installation of gloves of different sizes within a certain range.

[0017] In addition, before disassembling the gloves, the exhaust pipe is opened by controlling the solenoid valve, so that the high-pressure gas in the working chamber and the gloves can be discharged through the exhaust pipe, which significantly reduces the air pressure inside the gloves. This ensures that the gloves will not fly out under air pressure when they are disassembled, and facilitates the disassembly work. Attached Figure Description

[0024] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0025] like Figure 1 - Figure 2As shown, this embodiment provides a sealing performance testing device for the production of safety gloves, including a base 1 on which a work frame 3 is fixedly mounted, and a hydraulic drive mechanism 4 is installed on the work frame 3; a test cylinder seat 2, which is mounted on the base 1 and is generally frustoconical in shape, and the end of the glove is fitted onto the test cylinder seat 2 during testing; and a clamping ring seat 5, which is installed at the bottom of the hydraulic drive mechanism 4, and includes a ring seat body 51, in which a frustoconical groove corresponding to the test cylinder seat 2 is opened.

[0026] Based on the above scheme, the glove end fitted on the detection cylinder seat 2 is pressed and sealed by the pressing and fitting between the detection cylinder seat 2 and the pressing ring seat 5. Since the detection cylinder seat 2 is frustum-shaped and the pressing ring seat 5 has a frustum-shaped groove, when the pressing ring seat 5 is pressed onto the detection cylinder seat 2, it can simultaneously compress and fix various positions of the glove end over a large area without wrinkles, which can significantly improve the sealing performance of the glove installation and can be applied to the sealing installation of gloves of different sizes within a certain range.

[0027] To further improve the sealing of the installation, such as Figure 2 As shown, the detection cylinder base 2 includes a support cylinder 21, and a frustum-shaped rubber sleeve 22 is provided on the outer sleeve of the support cylinder 21. An annular rubber pad 52 is attached to the wall of the frustum-shaped groove of the ring seat body 51. Since both the rubber sleeve 22 and the annular rubber pad 52 have a certain elastic deformation capacity, they can fit tightly against the inner and outer walls of the glove port when subjected to compression, further improving the sealing of the glove installation and ensuring the accuracy of the detection results of the detection equipment.

[0028] To complete the entire testing process, a working chamber 23 is provided inside the support cylinder 21. A sealed inflation pipe 61, an exhaust pipe 62, and a pressure sensor 64 are installed inside the support cylinder 21. The inflation pipe 61 and exhaust pipe 62 connect to the working chamber 23, and the pressure sensor 64's detection head is located within the working chamber 23. Figure 2 - Figure 3 As shown.

[0029] Based on the above structural form, during operation, after the glove is sealed and installed, gas is filled into the sealed space formed by the working chamber 23 and the inside of the glove through the inflation tube 61. The pressure sensor 64 can monitor the change of air pressure in the sealed space. When the air pressure reaches the standard test value, the inflation tube 61 and the exhaust tube 62 are sealed. The sealing performance is judged by observing the change of air pressure in the sealed space within a specified time. At the same time, before disassembling the glove, the exhaust tube 62 is opened by controlling the solenoid valve 63, so that the high-pressure gas in the working chamber 23 and the glove can be discharged through the exhaust tube 62, which significantly reduces the air pressure inside the glove. This ensures that the glove will not fly out under the action of air pressure when it is disassembled, which facilitates the smooth disassembly work.

[0030] The bottoms of the inflation pipe 61 and the exhaust pipe 62 are bent and arranged horizontally in the base 1, and the ends of the inflation pipe 61 and the exhaust pipe 62 extend out of the base 1. The end of the inflation pipe 61 is sealed to the air pump 7 located on one side of the base 1. The bottom of the air pressure sensor 64 is electrically connected to the working cable 641, which is bent horizontally and extends out of the base 1. The above structure can complete the laying of pipelines and lines, ensuring that each can perform normal functions while being neatly arranged, which is convenient for subsequent maintenance.

[0031] In order to control the opening and closing of the ventilation and exhaust passages, solenoid valves 63 are installed at the bottom of both the inflation pipe 61 and the exhaust pipe 62. The solenoid valves 63 are bolted to the base 1. When inflation, the solenoid valve 63 of the inflation pipe 61 is open and the solenoid valve 63 of the exhaust pipe 62 is closed. When exhausting, the opening and closing of the solenoid valve 63 is the opposite.

[0032] When the glove is placed on the detection cylinder seat 2, it may bend and stick to the detection cylinder seat 2 under the action of gravity due to lack of support, thus affecting the normal downward movement of the clamping ring seat 5 and preventing it from being tightly pressed against the detection cylinder seat 2. Therefore, a glove support frame 8 is installed in the working cavity 23 to support the glove and keep it in an upright position. It is composed of several bent steel wires arranged in a circumferential array, such as... Figure 2 As shown, the above structure can support and constrain the finger part of the glove, preventing the upper part of the glove from bending and collapsing under the action of gravity, thus affecting the normal movement of the clamping ring seat 5.

[0033] like Figure 4 As shown, the work frame 3 includes a first gantry 31 fixedly mounted on the base 1, and a second gantry 32 mounted on its top. Meanwhile, the hydraulic drive mechanism 4 includes a hydraulic cylinder 41 mounted on the second gantry 32, with a connecting plate 42 fixedly connected to its rod end. Several guide rods 43 that are slidably connected to the first gantry 31 are fixedly connected to the bottom of the connecting plate 42. A pressure ring 44 that is bolted to the ring seat body 51 is fixedly connected to the bottom end of the guide rods 43. When it is necessary to drive the pressing ring seat 5 to move, the hydraulic cylinder 41 works to drive the guide rods 43 to move up and down through the connecting plate 42, and then drives the pressing ring seat 5 to move up and down as a whole through the pressure ring 44, so as to realize the pressing and separation between it and the detection cylinder seat 2.

[0034] The working principle and usage process of this utility model:

[0035] By pressing and fitting the detection cylinder seat 2 and the clamping ring seat 5 together, the end of the glove fitted on the detection cylinder seat 2 is pressed and sealed. Since the detection cylinder seat 2 is frustoconical and the clamping ring seat 5 has a frustoconical groove, when the clamping ring seat 5 is pressed onto the detection cylinder seat 2, it can simultaneously compress and fix various positions of the glove end over a large area without wrinkles, which can significantly improve the sealing performance of the glove installation and can be applied to the sealing installation of gloves of different sizes within a certain range.

[0036] During operation, after the glove is sealed and installed, gas is filled into the sealed space formed by the working chamber 23 and the inside of the glove through the inflation tube 61. The pressure sensor 64 can monitor the change of air pressure in the sealed space. When the air pressure reaches the standard test value, the inflation tube 61 and the exhaust tube 62 are sealed. The sealing performance is judged by observing the change of air pressure in the sealed space within a specified time.

[0037] Before disassembling the gloves, the exhaust pipe 62 is opened by controlling the solenoid valve 63, so that the high-pressure gas in the working chamber 23 and the gloves can be discharged through the exhaust pipe 62, which significantly reduces the air pressure inside the gloves. This ensures that the gloves will not fly out under the action of air pressure when they are disassembled, and facilitates the smooth disassembly work.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
