PVC glove airtightness tester

Abstract

This utility model relates to a PVC glove airtightness testing fixture, including an operating table, a tray, and a workstation conversion component. The glove to be tested is placed onto the mounting base with its opening closed. The bottom is lifted by hand, and a cylinder is activated to move the moving platform closer to the mounting base, thus moving the mounting base and fixing it between the moving platform and the fixed platform. When the mounting base is pushed, the sliding seat on the surface of the mounting base slides within a groove. Since adhesive layers are fixedly installed on adjacent sides of both the moving platform and the fixed platform, these adhesive layers press the glove against the mounting base. The adhesive layers can deform, ensuring a tight fit between the glove and the mounting base and preventing air leakage. At this point, an air pump is activated to introduce air into the hollow part of the mounting base, inflating the glove. The drive unit is activated to rotate the column, thereby controlling the rotation of the tray. The inflated glove is rotated above the water tank, and the cylinder is activated to move the water tank upwards. The inflated glove is then placed into the water tank, and it is observed whether air bubbles are generated. This system provides a dual testing method.

Description

Technical Field

[0001] This utility model relates to the technical field of glove airtightness testing equipment, specifically a PVC glove airtightness testing tool. Background Technology

[0002] In the production and manufacturing process of PVC gloves, air tightness is one of the key indicators for measuring glove quality. Traditional equipment simply checks the air tightness of the gloves by inflating them with air. If there is a slight leak on the surface of the gloves, the air tightness test is not intuitive enough.

[0003] For example, the authorized patent document with application number CN202323516559.3 discloses a testing device for detecting the air tightness of latex gloves. By driving the rotation and movement of the lead screw and movable block by a motor, the support rods can be brought closer together to ensure that the clamping block can tightly hold the latex glove, thereby ensuring that the glove can be stably installed on the outer surface of the air jet head. By driving the air pump, the gas can be accurately delivered from the air jet head to the latex glove. In the above structure, the gas is delivered from the air jet head to the latex glove. During the test, the latex glove testing device only uses the air jet head to inflate the glove. This is not intuitive enough for air tightness detection and it is difficult to quickly detect leaks. Therefore, we need to provide a PVC glove air tightness inspection tool. Utility Model Content

[0004] The purpose of this invention is to provide an airtightness tester for PVC gloves. By using a workstation conversion component to seal and fix the gloves, and then placing them in a water tank to observe the bubbles, it is possible to intuitively and accurately determine whether there is any air leakage in the gloves. Even tiny leaks will be detected by the formation of bubbles as gas escapes, greatly reducing detection errors. The dual detection method, which combines air inflation and water testing, verifies the airtightness of the gloves from different angles, solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PVC glove airtightness testing tool, comprising:

[0006] The control panel, the tray, and the workstation conversion component are provided. The tray is located inside the control panel and has a workstation conversion component inside, which is used to fix, seal, test, and air dry gloves.

[0007] The workstation conversion component includes an air pump, mounting bases, and fixing components. Three hollow mounting bases are installed inside the operating table. The air pump is installed on the top of the plate and is connected to the hollow parts inside the three mounting bases. The surface of the plate is provided with fixing components for fixing gloves to the mounting bases.

[0008] Preferably, the air pump includes an air pipe and a pump body, the pump body is fixed on the top of the disc, the mounting base is connected to the main body by an air pipe, and the air pipe is provided with a corrugated pipe.

[0009] Preferably, a slide is fixedly mounted on the surface of the mounting base, and a sliding groove for the slide is provided in the operating table. The top and bottom edges of the slide are provided with protruding strips to prevent the slide from falling off.

[0010] Preferably, the fixing component includes an electric push rod, a fixed platform, and a movable platform. The fixed platform is fixedly installed on the bottom of the disc body, located on one side of the mounting base. The movable platform is fixed to the extension end of the electric push rod, located on the other side of the fixed base. Adhesive layers are fixedly installed on the adjacent sides of the fixed platform and the movable platform.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention achieves sealed fixation of the gloves through a workstation conversion component, effectively preventing air leakage at the connection between the gloves and the testing equipment during the testing process. The air pump inflates the sealed gloves, bringing the internal pressure to a set value. Then, the gloves are placed in a water tank to observe the bubbles, allowing for a direct and accurate assessment of whether there is any air leakage.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a PVC glove airtightness tester, comprising:

[0024] The control panel 1, the tray 2, and the workstation conversion component 3 are located inside the control panel 1 and are equipped with the workstation conversion component 3 inside, which is used to fix, seal, test and air dry the gloves.

[0025] The workstation conversion component 3 includes an air pump 31, a mounting base 32, and a fixing component 33. Three hollow mounting bases 32 are installed inside the operating table 1. The air pump 31 is installed on the top of the disc body 2 and is connected to the hollow part inside the three mounting bases 32. The surface of the disc body 2 is provided with a fixing component 33 for fixing gloves to the mounting bases 32.

[0026] Specifically, by providing a workstation conversion component 3 on the surface of the disc body 2, the gloves can be sealed and fixed. The sealed and fixed gloves are inflated by an air pump 31, and the inflated gloves are placed in the water in the water tank 7 for observation. The presence of air bubbles in the water is observed to determine whether there is any leakage. The gloves tested in the water can also be air-dried.

[0027] The sealing and fixing of the gloves via the workstation conversion component 3 effectively prevents air leakage at the connection between the gloves and the testing equipment during the testing process, ensuring that the test results only reflect the airtightness of the gloves themselves. The air pump 31 inflates the sealed gloves, bringing the internal pressure to a set value. Then, the gloves are placed in the water tank 7 to observe bubbles, allowing for a direct and accurate assessment of any leaks. Even tiny leaks will be detected by the escaping gas forming bubbles, greatly reducing testing errors. This dual testing method, combining inflation and underwater inspection, verifies the gloves' airtightness from different angles. The inflation process can initially determine if there are significant leaks, while underwater observation further confirms minor leaks; the two methods complement each other.

[0028] The air pump 31 includes an air pipe 311 and a pump body 312. The pump body 312 is fixed on the top of the disc 2. The mounting base 32 is connected to the main body by an air pipe 311, and a corrugated pipe is provided inside the air pipe 311.

[0029] Furthermore, an air pipe 311 connects the mounting base 32 and the pump body 312, and a corrugated pipe is installed inside the air pipe 311. During operation, the airflow generated by the pump body 312 is transmitted to the mounting base 32 through the air pipe 311. The corrugated pipe can extend and retract appropriately during the airflow transmission to adapt to the changes in the position of the mounting base 32 when the disc 2 rotates. This setting ensures that the air path remains connected and stable during the rotation of the disc 2 and the movement of the mounting base 32, avoiding damage to the air pipe 311 or obstruction of airflow transmission due to pulling or bending. This ensures that the air pump 31 can continuously and stably inflate the glove, improving the stability and reliability of the airtightness test.

[0030] A slide block 4 is fixedly mounted on the surface of the mounting base 32. A slide groove 5 for sliding the slide block 4 is provided in the operating table 1. The top and bottom edges of the slide block 4 are provided with protruding strips to prevent the slide block 4 from falling off.

[0031] It is worth noting that when the mounting base 32 is pushed to adjust its position, the slide 4 slides in the slide groove 5. The protrusions on the top and bottom edges of the slide 4 can be embedded in the corresponding positions of the slide groove 5, restricting the slide 4 from disengaging from the slide groove 5 in the vertical direction. This structural design enables the mounting base 32 to maintain a stable trajectory during movement, preventing the mounting base 32 from shifting or falling off, ensuring the stability of glove fixing and the detection process, and thus improving the accuracy of detection.

[0032] The fixing component 33 includes an electric push rod 331, a fixed platform 332 and a movable platform 333. The fixed platform 332 is fixedly installed at the bottom of the disc body 2 and located on one side of the mounting base 32. The movable platform 333 is fixed at the extension end of the electric push rod 331 and located on the other side of the fixed base. Adhesive layers are fixedly installed on the adjacent sides of the fixed platform 332 and the movable platform 333.

[0033] Specifically, the electric push rod 331 is activated, driving the moving stage 333 to move towards the mounting base 32 until the moving stage 333 and the fixed stage 332 clamp the mounting base 32. During this process, the adhesive layer is compressed and deformed, tightly adhering to the glove and pressing it onto the mounting base 32. The electric push rod 331 precisely controls the moving distance and force of the moving stage 333, which, together with the deformable adhesive layer, enables the glove to be quickly, firmly, and sealed on the mounting base 32. This prevents air leakage during the testing process, ensures the accuracy of the test results, and also improves the automation and ease of operation of glove fixing.

[0034] A cylinder 6 is installed inside the control panel 1. A water tank 7 is fixedly installed on the upper end of the cylinder 6. The water tank 7 is located at the bottom of one of the mounting bases 32.

[0035] In the process of testing the airtightness of gloves, after the gloves are inflated, cylinder 6 is activated, pushing water tank 7 upward to immerse the inflated glove above water tank 7 into the water inside. After the test is completed, cylinder 6 moves water tank 7 downward to reset, so that the next glove can be tested. This structure achieves precise coordination between the position of water tank 7 and glove through the precise lifting and lowering control of cylinder 6, enabling the underwater testing process to proceed smoothly and allowing for quick switching of the test object, thus improving testing efficiency. At the same time, the lifting and lowering action of water tank 7 coordinates with the operation of other workstations, ensuring the continuity of the entire testing process. Furthermore, water tank 7 is a transparent water tank.

[0036] A fan 8 is fixedly installed inside the operating table 1. The fan 8 is used to dry the gloves after testing.

[0037] Specifically, after the gloves have been inflated and tested in water, the drive unit 10 drives the disc 2 to rotate, moving the tested gloves to the side of the fan 8. The fan 8 is then activated, blowing out airflow to dry the moisture on the surface of the gloves. This design enables rapid drying of the gloves after testing, and the air inlet of the fan 8 is equipped with a protective layer to intercept dust.

[0038] A column 9 is fixedly installed at the axis of the disc body 2. The column 9 is rotatably installed inside the operating table 1, and the operating table 1 is provided with a drive unit 10 for rotating the column 9.

[0039] When it is necessary to switch glove inspection stations, the drive unit 10 is activated, driving the column 9 to rotate. The column 9 drives the disc 2 to rotate, so that the glove on the mounting base 32 moves to the corresponding station with the disc 2. This structure achieves flexible rotation of the disc 2 through the cooperation of the column 9 and the drive unit 10, thereby completing the rapid switching between multiple stations. In addition, the water pump and the cylinder 6 are both reserved with enough wiring to rotate two revolutions. After the disc 2 rotates one revolution, it rotates in the opposite direction to reset, avoiding excessive winding of the wiring.

[0040] The drive unit 10 includes a stepper motor 101, a drive wheel 102 and a driven wheel 103. The driven wheel 103 is fixed on the surface of the column 9. The stepper motor 101 is installed in the operating table 1, and the output end is equipped with a drive wheel 102 that meshes with the driven wheel 103.

[0041] Furthermore, during operation, the stepper motor 101 is powered on and starts, and its output drives the drive wheel 102 to rotate. The drive wheel 102 transmits power to the column 9 through meshing with the driven wheel 103, causing the column 9 to rotate precisely. The stepper motor 101 can achieve precise angle control and speed adjustment. Together with the meshing transmission between the drive wheel 102 and the driven wheel 103, it ensures the accuracy of the rotation angle and speed of the disc 2, so that the glove can move precisely to each predetermined inspection station and ensure the orderly progress of the inspection process.

[0042] The cylinder 6, air pump 31, electric push rod 331, fan 8 and stepper motor 101 involved in this application are all implemented using existing mature technologies and are all waterproof. They are connected to an external PLC controller and power supply, which are conventional technical means in this field. Therefore, their specific circuit connections, control logic and working processes will not be described in detail.

[0043] The device involves slipping the opening of the glove to be tested onto the mounting base 32, lifting the bottom by hand, and activating cylinder 6 to move the moving stage 333 closer to the mounting base 32, thus moving the mounting base 32 and fixing it between the moving stage 333 and the fixed stage 332. When the mounting base 32 is pushed, the sliding block 4 on the surface of the mounting base 32 slides within the sliding groove 5. Since adhesive layers are fixedly installed on adjacent sides of the moving stage 333 and the fixed stage 332, the adhesive layers press the glove onto the mounting base 32. The adhesive layers can deform, allowing the glove to fit tightly against the mounting base 32, preventing air leakage. At this time, the device is activated. The air pump 31 introduces air into the hollow space of the mounting base 32 to inflate the glove. This allows for observation of any large leaks. The drive unit 10 is activated to rotate the column 9, thereby controlling the rotation of the disc 2. The inflated glove is then rotated above the water tank 7, which is transparent and filled with water. The cylinder 6 is activated to move the water tank 7 upwards, and the inflated glove is placed inside. The presence of air bubbles is observed, providing a dual detection method. After detection, the water tank 7 is lowered, and the detected glove is rotated to the side of the fan 8 for air drying. Meanwhile, the water tank 7 can then be used to detect the next glove.
