Description

Technical Field

[0001] This utility model belongs to the technical field of PVC glove inspection tools, specifically referring to a PVC glove airtightness inspection tool. Background Technology

[0002] PVC gloves are made of polyvinyl chloride through a special process, giving them strong chemical resistance, good flexibility and feel, and making them easy and comfortable to wear. They also have anti-static properties and can be used in cleanroom environments. However, during the production process, some parts of the PVC gloves may be damaged, leading to leaks during use. Therefore, airtightness testing is necessary during the manufacturing process.

[0003] Existing methods for testing the air tightness of PVC gloves often involve directly inflating the gloves and immersing them in water to observe for leaks. However, this type of air tightness tester is prone to causing the gloves to fall off during water immersion testing, and it is also inconvenient to dry the PVC gloves after testing. Therefore, there is an urgent need for an air tightness tester for PVC gloves to solve the above problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing PVC gloves are inconvenient to tighten the cuffs to prevent them from falling off during airtightness testing, and it is also inconvenient to keep the tested PVC gloves dry.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a PVC glove airtightness tester, including a water tank and a support box fixedly installed on the water tank, and an airtightness testing mechanism installed on the support box, and a drying mechanism installed on the water tank.

[0006] To facilitate the automatic lifting and immersion of PVC gloves in water for leak detection, the air tightness detection mechanism includes a threaded rod rotatably connected between the top and bottom walls of a support box. A drive motor for rotating the threaded rod is fixedly mounted on the top wall of the support box. Another set of guide rods is fixedly mounted between the top and bottom walls of the support box. A movable plate is threadedly connected to the threaded rod. A connecting seat is fixedly mounted on the movable plate. A rotary motor is fixedly mounted on one set of connecting seats. A rotating shaft is connected to the output end of the rotary motor. An electric air pump is fixedly mounted on the rotating shaft.

[0007] In order to facilitate the opening of PVC gloves to check for leaks, the bottom of the electric air pump is fixedly equipped with a support plate, and a telescopic cylinder is fixedly connected to the support plate. The telescopic end of the telescopic cylinder is connected to a movable sleeve.

[0008] To facilitate the drying of PVC gloves after airtightness testing, the drying mechanism includes a fixing block fixed on the side wall of the water tank, a support base inserted into the fixing block, a cover fixed on the top of the support base, a drying motor fixed on the inner wall of the cover, and a fan blade connected to the output end of the drying motor.

[0009] Furthermore, each side wall of the water tank is provided with a transparent sealing plate, and the top and bottom of the side wall of the water tank are respectively provided with a water inlet pipe and a water outlet pipe. The side wall of the support box is provided with an opening that is slidably connected to the movable plate.

[0010] Furthermore, the support box is symmetrically arranged at both ends of the water tank, and the telescopic cylinder and the movable sleeve are symmetrically arranged at both ends of the support plate.

[0011] Preferably, the connecting seat is U-shaped, and the movable sleeve and the support seat are both L-shaped.

[0012] The beneficial effects of this utility model by adopting the above structure are as follows:

[0013] 1. By turning on the drive motor, the electric air pump can be raised and lowered, which makes it easy to immerse the PVC gloves secured by the movable jacket into the water tank for airtightness testing to prevent them from coming off.

[0014] 2. By turning on the drying motor, the fan blades can be rotated, thus facilitating the automated drying process of PVC gloves after the airtightness test is completed. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: a PVC glove airtightness tester includes a water tank 1, each side wall of the water tank 1 is provided with a transparent sealing plate, the top and bottom of the side wall of the water tank 1 are respectively provided with a water inlet pipe and a water outlet pipe, and a support box 2 fixedly installed on the water tank 1. The support box 2 is symmetrically arranged at both ends of the water tank 1. It also includes an airtightness testing mechanism 3, which is installed on the support box 2. It also includes a drying mechanism 4, which is installed on the water tank 1.

[0023] like Figure 2-3 As shown, the airtightness testing mechanism 3 includes a threaded rod 5 rotatably connected between the top and bottom walls of the support box 2. A drive motor 6 for driving the threaded rod 5 to rotate is fixed on the top wall of the support box 2. Another set of guide rods 7 are fixed between the top and bottom walls of the support box 2. A movable plate 8 is threadedly connected to the threaded rod 5. An opening for sliding connection with the movable plate 8 is provided on the side wall of the support box 2. A connecting seat 9 is fixed on the movable plate 8. The connecting seat 9 is U-shaped. A rotary motor 10 is fixed on one set of connecting seats 9. A rotating shaft 11 is connected to the output end of the rotary motor 10. An electric air pump 12 is fixed on the rotating shaft 11. A support plate 13 is fixed at the bottom of the electric air pump 12. A telescopic cylinder 14 is passed through the support plate 13 and fixedly connected to it. A movable sleeve 15 is connected to the telescopic end of the telescopic cylinder 14. The telescopic cylinder 14 and the movable sleeve 15 are symmetrically arranged at both ends of the support plate 13.

[0024] like Figure 2 , 4 As shown, the drying mechanism 4 includes a fixing block 16 fixedly installed on the side wall of the water tank 1, a support base 17 inserted into the fixing block 16, the movable sleeve 15 and the support base 17 are both L-shaped, a cover 18 is fixedly installed on the top of the support base 17, a drying motor 19 is fixedly installed on the inner wall of the cover 18, and a fan blade 20 is connected to the output end of the drying motor 19.

[0025] In practical use, the user injects soapy water into the water tank 1 through the water inlet pipe, then places the opening of the PVC glove to be tested over the bottom of the air pump 12. The two sets of telescopic cylinders 14 are activated to extend the PVC glove, causing the two sets of movable clamps 15 to move relative to each other, clamping the opening of the PVC glove to the bottom of the air pump 12. The electric air pump 12 is then activated to inflate the PVC glove. The drive motor 6 is then activated to rotate forward, causing the threaded rod 5 to rotate forward as well. The two sets of movable plates 8 move downwards along the guide rod 7, immersing the PVC glove in the soapy water in the water tank 1. The user can then observe the inflated PVC glove through the transparent sealing plate. No air bubbles are generated, which allows observation of the airtightness of the PVC gloves. After the test is completed, the drive motor 6 is turned on to reverse and drive the PVC glove platform to rise and leave the soapy water in the water tank 1. The support base 17 is inserted into the fixing block 16 to fix the drying mechanism 4 on the water tank 1. The drying motor 19 is turned on to drive the fan blades 20 to rotate and blow air onto the PVC gloves for drying. The rotary motor 10 is turned on to drive the rotating shaft 11 to rotate and adjust the angle with the PVC gloves, so that the PVC gloves can be turned over for even air drying. The above is the entire process of using the PVC glove airtightness tester.
