Description

Technical Field

[0001] The utility model relates to the technical field of nitrile glove production, in particular to a defect detection device for nitrile glove production. Background Art

[0002] Nitrile gloves are protective gloves made of polynitrile material, usually used in medical, laboratory, cleaning and industrial fields. They are oil-resistant, chemical-resistant, wear-resistant and anti-allergic, and are more durable than latex gloves and more suitable for people who are allergic to latex. Nitrile gloves are usually available in different thicknesses and colors, and you can choose the right gloves according to your specific needs; defect detection is an indispensable process in the production of nitrile gloves. Defect detection can help manufacturers ensure that product quality meets standard requirements and avoid product returns or recalls due to defects. Air tightness detection can be classified as a defect detection. By testing the air tightness of gloves, it can be determined whether the gloves have air leaks or other sealing problems, thereby ensuring the quality and safety of the gloves;

[0003] Since the existing devices directly put nitrile gloves on the outside of the pipe for inflating when performing air tightness testing on them, and no corresponding positioning mechanism is provided to limit the resistance of the nitrile gloves, it is very easy for the nitrile gloves to directly fall off the testing device due to the excessive force of the inflation pressure, thereby directly affecting the final test results. However, the existing devices have not made improvements to this problem, and the overall practical effect is poor. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned problem and to propose a defect detection device for nitrile glove production, which improves the existing device that directly puts the nitrile gloves on the outside of the pipe for inflation when performing air tightness detection on the nitrile gloves, and does not provide a corresponding positioning mechanism to limit the nitrile gloves, which can easily lead to the phenomenon that the nitrile gloves directly fall off the detection device due to the excessive force of the inflation pressure, thereby directly affecting the final detection result.

[0005] A defect detection device for nitrile glove production, comprising a detection box: a detection control mechanism is arranged inside the detection box, a portable installation mechanism is arranged above the detection box, a resistance support mechanism is arranged on the side of the portable installation mechanism, the detection control mechanism comprises an air pump, a main conduit, a secondary conduit and a pneumatic one-way valve, an air pump is arranged on the inner wall of the bottom end of the detection box, the air pump is fixedly connected to the main conduit, secondary conduits are installed at equal intervals on the top outer wall of the main conduit, the output end of the secondary conduit passes through the top outer wall of the detection box and is arranged above the detection box, and a pneumatic one-way valve is arranged outside the secondary conduit.

[0006] Preferably, the portable installation mechanism comprises a threaded ring and a mounting ring, the top outer wall of the detection box is symmetrically provided with threaded rings at equal intervals, the threaded ring is arranged outside the secondary conduit, and the mounting ring is arranged outside the threaded ring.

[0007] Preferably, a thread groove is provided on the inner wall of the side of the mounting ring, a threaded mounting is performed between the thread ring and the thread groove, and an annular groove is provided on the outer wall of the side of the mounting ring.

[0008] Preferably, the abutment support mechanism comprises positioning blocks, and two groups of positioning blocks are symmetrically arranged on the side outer wall of the mounting ring below the annular groove, and there are two positioning blocks in the same group.

[0009] Preferably, a support shaft is connected between the side outer walls of the two positioning blocks, a support box is rotatably mounted outside the support shaft, and a control panel is provided on the side outer wall of the support box at the bottom end.

[0010] Preferably, a torsion spring is sleeved on the outside of the support shaft, one end of the torsion spring is connected to the support shaft, and the other end of the torsion spring is connected to the inner wall of the side of the support box.

[0011] Preferably, a support frame is provided on the top outer wall of the support box, and the support frame is arranged in an inverted "L" shape.

[0012] Preferably, a resistance pad is provided on the side outer wall of the support frame, and the resistance pad is snap-fitted to the annular groove.

[0013] The beneficial effects of the utility model are:

[0014] 1. When the defect detection device for nitrile glove production is in use, the annular groove is provided on the outside of the installation ring, and the annular groove is used to perform a first resistance limit on the nitrile glove when the nitrile glove is installed. The positioning block, the support shaft, the support box, the control panel, the torsion spring, the support frame and the resistance pad are further provided, and the force of the torsion spring is used to automatically drive the resistance pad to move and reset, so that the resistance pad can resist the inside of the annular groove to perform a second resistance limit on the nitrile glove. Combining the above designs, the device can well perform resistance limit on the nitrile glove to be tested, and avoids the phenomenon of the nitrile glove being separated from the device due to unstable positioning during the inflation detection process. The overall structural design is ingenious and has good practical effect.

[0015] 2. When the defect detection device for nitrile glove production is in use, the air pump, the main conduit, the secondary conduit and the pneumatic one-way valve are set up.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figures 1-6As shown, a defect detection device for nitrile glove production includes a detection box 1: a detection control mechanism 2 is arranged inside the detection box 1, a portable installation mechanism 3 is arranged above the detection box 1, and a resistance support mechanism 4 is arranged on the side of the portable installation mechanism 3. The detection control mechanism 2 includes an air pump 21, a main conduit 22, a secondary conduit 23 and a pneumatic one-way valve 24. The bottom inner wall of the detection box 1 is provided with an air pump 21, the air pump 21 is fixedly connected to the main conduit 22, and the top outer wall of the main conduit 22 is connected and installed with secondary conduits 23 at equal intervals. The output end of the secondary conduit 23 passes through the top outer wall of the detection box 1 and is arranged above the detection box 1, and the outside of the secondary conduit 23 is provided with a pneumatic one-way valve 24; When the nitrile gloves to be tested need to be inflated, the air pump 21 needs to be turned on to supply air first. When the air pump 21 is turned on, the gas will be automatically transported to the inside of the main duct 22, and then distributed to the inside of each secondary duct 23 through the guidance of the main duct 22, and then injected into the inside of the nitrile gloves through the guidance of the secondary duct 23. When the nitrile gloves are inflated to meet the inspection standard, the air pump 21 can be turned off. The pneumatic one-way valve 24 is set here to avoid the phenomenon of gas reflux and ensure the airtight integrity of the nitrile gloves. The air pump 21 is powered by existing technology and can be powered by a power supply unit or an external wire. No further description will be given here.

[0025] The portable installation mechanism 3 includes a threaded ring 31 and a mounting ring 32. The threaded rings 31 are symmetrically arranged on the top outer wall of the detection box 1 at equal intervals. The threaded ring 31 is arranged on the outside of the secondary duct 23. The mounting ring 32 is arranged on the outside of the threaded ring 31. A threaded groove 33 is provided on the inner wall of the side of the mounting ring 32. There is a threaded installation between the threaded ring 31 and the threaded groove 33, and an annular groove 34 is provided on the outer wall of the side of the mounting ring 32. When it is necessary to install the mounting ring 32 with nitrile gloves installed on the top of the device, it is only necessary to adjust the threaded groove 33 inside the mounting ring 32 to a suitable position and then screw it to the outside of the threaded ring 31. The setting of the annular groove 34 here provides a mounting support point for the nitrile gloves.

[0026] The interference support mechanism 4 includes a positioning block 41. Two groups of positioning blocks 41 are symmetrically arranged on the outer side wall of the mounting ring 32 below the annular groove 34. Two positioning blocks 41 are provided in the same group. A support shaft 42 is connected between the outer side walls of the two positioning blocks 41. A support box 43 is rotatably installed on the outside of the support shaft 42. A control board 44 is arranged on the outer side wall of the bottom end of the support box 43. A torsion spring 45 is sleeved on the outside of the support shaft 42. One end of the torsion spring 45 is connected to the support shaft 42, and the other end of the torsion spring 45 is connected to the inner side wall of the support box 43. A support frame 46 is arranged on the top outer wall of the support box 43. The support frame 46 is arranged in an inverted "L" shape. An interference pad 47 is arranged on the outer side wall of the support frame 46. The interference pad 47 is snap-fitted with the annular groove 34; before the above-mentioned nitrile glove needs to be sleeved onto the annular groove 34, first, the control board 44 needs to be toggled downward. Then, when the control board 44 deflects downward, it will automatically drive the support box 43 to move along a circular motion trajectory with the support shaft 42 as the rotation axis. When the support box 43 moves, it will automatically drive the torsion spring 45 to contract and twist tightly. At the same time, when the support box 43 moves, it will also synchronously drive the support frame 46 to move, thereby driving the interference pad 47 to move out of the annular groove 34. Subsequently, the nitrile glove is sleeved on the outside of the mounting ring 32, and it is ensured that the mounting end of the nitrile glove is located inside the annular groove 34. Then, the control board 44 is released. At this time, when the torsion spring 45 is not affected by force, it will automatically drive the support box 43 to reset. Then, when the support box 43 resets, it will automatically drive the support frame 46 to move, thereby driving the interference pad 47 to snap back into the annular groove 34 again. Thus, the nitrile glove is interferentially limited by the interference pad 47. The removal method is the same.

[0027] When the present utility model is in use, first, the nitrile glove needs to be sleeved on the outside of the mounting ring 32. Before the above-mentioned nitrile glove needs to be sleeved onto the annular groove 34, first, the control board 44 needs to be toggled downward. Then, when the control board 44 deflects downward, it will automatically drive the support box 43 to move along a circular motion trajectory with the support shaft 42 as the rotation axis. When the support box 43 moves, it will automatically drive the torsion spring 45 to contract and twist tightly. At the same time, when the support box 43 moves, it will also synchronously drive the support frame 46 to move, thereby driving the interference pad 47 to move out of the annular groove 34. Subsequently, the nitrile glove is sleeved on the outside of the mounting ring 32, and it is ensured that the mounting end of the nitrile glove is located inside the annular groove 34. Then, the control board 44 is released. At this time, when the torsion spring 45 is not affected by force, it will automatically drive the support box 43 to reset. Then, when the support box 43 resets, it will automatically drive the support frame 46 to move, thereby driving the interference pad 47 to snap back into the annular groove 34 again. Thus, the nitrile glove is interferentially limited by the interference pad 47;

[0028] Subsequently, the mounting ring 32 with nitrile gloves installed is mounted above the device. At this time, only the threaded groove 33 inside the mounting ring 32 needs to be adjusted to a proper position and then screwed onto the outside of the threaded ring 31. At this time, repeat the above steps to install the nitrile gloves above the device in sequence. After the installation is completed, the nitrile glove to be detected is inflated. At this time, it is first necessary to turn on the air pump 21 to supply air. Then, when the air pump 21 is turned on, it will automatically transport the gas into the main conduit 22. Subsequently, it is guided by the main conduit 22 and distributed into the internal parts of each sub-conduit 23. Then, it is injected into the internal part of the nitrile glove through the guidance of the sub-conduit 23. When the nitrile glove is inflated to the detection standard, turn off the air pump 21 at this time. The setting of the pneumatic one-way valve 24 here is to avoid the phenomenon of gas backflow and ensure the airtight integrity of the nitrile glove during gas injection. The air pump 21 is powered by existing technology, and it can be powered by installing a power supply component or connecting an external wire, which will not be described in detail here. Subsequently, penetrate the nitrile glove. If it does not deflate after inflation, it means its airtightness is intact, and if it does not bulge after inflation, its airtightness is damaged, thereby achieving the effect of airtightness detection.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
