Abstract
Description
Technical Field
[0001] This utility model relates to the field of latex glove testing technology, and in particular to an inflation testing machine for the production of high-performance environmentally friendly latex gloves. Background Technology
[0002] Latex gloves, with their excellent elasticity, barrier properties, and comfort, are widely used in medical, food, and electronics fields. With the deepening of environmental protection concepts, high-performance environmentally friendly latex gloves have further reduced their negative impact on the environment by optimizing raw material formulations and production processes, while maintaining the excellent performance of traditional latex gloves. Market demand and application scope continue to expand.
[0003] However, latex gloves may develop defects such as micropores, cracks, or uneven thickness during the production process due to factors such as material uniformity, molding process, or mold residue. These defects can seriously affect the airtightness and safety of the gloves. Therefore, airtightness testing must be performed to ensure the safe use of latex gloves.
[0004] Currently, the industry commonly uses the air-inflation and water immersion method for testing: the gloves are inflated and then immersed in water, and leaks are determined by observing the bubbles. However, in actual testing, latex gloves are lightweight, and their overall density after inflation is much lower than that of the liquid, making them difficult to stabilize due to buoyancy. Additional tools are needed to press and fix them, making the operation cumbersome, and incomplete immersion may affect the accuracy of the test. Secondly, products tested in water need to be dried, increasing costs and energy consumption, and extending the testing cycle. Utility Model Content
[0005] This invention addresses the shortcomings of existing testing methods by providing a high-performance, environmentally friendly latex glove inflation testing machine that is efficient and convenient for testing.
[0006] The technical implementation scheme of this utility model is as follows: a high-performance environmentally friendly latex glove production inflation testing machine, comprising: a base; a mounting frame, fixedly connected to the base; a connecting pipe, fixedly connected to the top center of the mounting frame, the size of which is larger than the size of the wrist opening of the latex glove; a clamping assembly, located on the outer periphery of the connecting pipe, used to stably and sealably clamp the latex glove onto the connecting pipe; an air inlet pipe, fixedly connected to the mounting frame, with an air pump built into the base, and both ends of the air inlet pipe connected to the connecting pipe and the air pump respectively; limiting rods, respectively fixedly connected to the lower two sides of the mounting frame; clamping plates, respectively slidably connected to the limiting rods on both sides, located directly below the connecting pipe, with the latex glove placed on the connecting pipe and positioned between the two clamping plates; and a second spring, sleeved on the limiting rod, one end of which is fixed to the clamping plate and the other end of which is fixed to the mounting frame.
[0007] In a preferred embodiment of this utility model, the clamping assembly includes: a sliding sleeve, slidably connected to the outer periphery of the connecting pipe opening, displacing axially along the connecting pipe, with its lower inner diameter larger than the diameter of the connecting pipe opening; a clamping block, slidably connected to the lower part of the sliding sleeve, displacing radially along the sliding sleeve, with at least two sets evenly distributed on the inner side of the lower part of the sliding sleeve; a first spring, sleeved on the sliding shaft of the clamping block, with one end fixed to the clamping block and the other end fixed to the sliding sleeve; and a control ring, threadedly connected to the outer periphery of the sliding sleeve, with its inner diameter decreasing progressively from bottom to top, covering all clamping blocks, and the end of the sliding shaft of the clamping block contacting its inner wall.
[0008] In a preferred embodiment of the present invention, the device further includes: a laser, fixedly connected to the lower part of one of the clamps; a receiver, fixedly connected to the lower part of the mounting bracket, through which the laser passes and is used to capture the positional changes of the laser beam; and a central control unit, fixedly connected to the base and electrically connected to the receiver, which has a built-in data processing unit and a display screen.
[0009] In a preferred embodiment of the present invention, the device further includes: a pressure sensor, which is fixedly connected to the middle section of the air inlet pipe, communicates with the inside of the air inlet pipe, and is connected to the electrical signal of the central control console, for real-time monitoring of the gas pressure value delivered by the air pump to the latex glove.
[0010] In a preferred embodiment of this utility model, the device further includes: an indicator light, which is fixedly connected to the mounting bracket and electrically connected to the central control console, for use in providing feedback on the detection progress of the device.
[0011] In a preferred embodiment of the present invention, the device further includes: an adjustable support foot, fixedly connected to the bottom of the base, for adjusting the overall levelness of the device.
[0012] Compared with the prior art, the present invention has the following advantages: The present invention directly reflects the airtightness of latex gloves through the displacement change of the clamping plate, and the detection process is intuitive and the results are reliable; Compared with the traditional water immersion detection method, the present invention avoids the addition of extra processing steps due to the detection process, achieving a double saving of operation time and energy consumption; In addition, the present invention has a simple and reasonable overall structure, responds quickly, and can effectively improve detection efficiency and reduce overall cost while achieving efficient and non-destructive testing.
[0013] The clamping assembly used in this invention has a structure in which the clamping force is evenly applied along the outer periphery of the latex glove's wrist opening. The large contact area between the clamping surface and the latex glove, along with the gentle force distribution, effectively prevents excessive local pressure from causing clamping marks or damage to the latex glove. This also prevents misjudgment of airtightness defects due to clamping damage, thus improving the authenticity and reliability of the test results. Furthermore, the clamping and unlocking are controlled by rotating the control ring, making the operation simple. The threaded engagement achieves self-locking, maintaining stable clamping performance and preventing accidental loosening during the testing process. Attached Figure Description

Detailed Implementation
[0018] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.
[0019] Example: A high-performance, environmentally friendly latex glove manufacturing inflation testing machine, such as... Figures 1-2 As shown, the device includes: a base 1; a mounting frame 2, fixedly mounted on the base 1; a connecting pipe 3, fixedly mounted on the top center of the mounting frame 2, with its opening size larger than the wrist opening of the latex glove to achieve stable fitting of the latex glove; a clamping assembly, located on the outer periphery of the connecting pipe 3, used to stably and seal the latex glove onto the connecting pipe 3, ensuring airtightness when the latex glove is inflated; an air inlet pipe 4, fixedly mounted on the mounting frame 2, with an air pump built into the base 1, and both ends of the air inlet pipe 4 connected to the connecting pipe 3 and the air pump respectively, supplying air to the latex glove fitted onto the connecting pipe 3; limiting rods 10, fixedly mounted on both sides of the lower part of the mounting frame 2; clamping plates 9, slidably mounted on the limiting rods 10 on both sides, located directly below the connecting pipe 3, with the latex glove positioned between the two clamping plates 9 after being fitted onto the connecting pipe 3; and a second spring 11, sleeved on the limiting rods 10, with one end fixed to the clamping plate 9 and the other end fixed to the mounting frame 2.
[0020] During testing, the latex glove is fitted onto the opening of the connecting pipe 3 and sealed and secured using the clamping assembly. The air pump is started, and gas is injected into the latex glove through the air inlet pipe 4 and the connecting pipe 3. The latex glove gradually expands and pushes the two clamping plates 9 to separate to both sides along the limiting rod 10, compressing the second spring 11. Once the latex glove is inflated to the preset shape, the air pump is turned off. If the latex glove's airtightness meets the standard, its internal air pressure is stable, and it can stably resist the pressure from the clamping plates 9 and the second spring 11, so the position of the clamping plates 9 remains unchanged. If the latex glove has an airtightness defect, the internal gas is squeezed by the clamping plates 9 under the pressure of the second spring 11, causing leakage. Therefore, after the air pressure drops, the clamping plates 9 will reset along the limiting rod 10 under the elastic force of the second spring 11. Thus, by observing whether the clamping plates 9 have shifted, it is possible to quickly determine whether the latex glove is leaking, and the test results are intuitive and clear.
[0021] like Figures 1-3 As shown, the clamping assembly includes: a sliding sleeve 5, which is slidably installed on the outer periphery of the pipe opening of the connecting pipe 3 and moves axially along the connecting pipe 3, with its lower inner diameter being larger than the diameter of the connecting pipe 3; a clamping block 6, which is slidably installed on the lower part of the sliding sleeve 5 and moves radially along the sliding sleeve 5, and there are four sets of clamping blocks 6 evenly distributed on the lower inner side of the sliding sleeve 5; a first spring 7, which is sleeved on the sliding shaft of the clamping block 6, with one end fixed to the clamping block 6 and the other end fixed to the sliding sleeve 5; and a control ring 8, which is threadedly installed on the outer periphery of the sliding sleeve 5, with its inner diameter decreasing progressively from bottom to top, covering all the clamping blocks 6, and the end of the sliding shaft of the clamping block 6 contacting its inner wall.
[0022] First, support the sliding sleeve 5 upwards to expose the opening of the connecting pipe 3, and then put the latex glove onto the opening of the connecting pipe 3. After the latex glove is put on, move the sliding sleeve 5 downwards to move the clamping block 6 to the position corresponding to the wrist opening of the latex glove. Rotate the control ring 8 to make it move downwards relative to the sliding sleeve 5. Its inner wall will then squeeze the clamping block 6, pushing the clamping block 6 to move radially inwards, thus stably clamping the latex glove. During this process, the first spring 7 is compressed. Through the threaded self-locking characteristic of the control ring 8 and the sliding sleeve 5, the position of the control ring 8 remains fixed, thereby making the clamping block 6 maintain a constant clamping force on the latex glove, ensuring the sealing effect between the latex glove and the opening of the connecting pipe 3, and preventing gas from leaking from the interface between the latex glove and the connecting pipe 3 during inflation. After the test is completed, reverse the control ring 8 so that it no longer applies a squeezing force to the clamping block 6. Then the first spring 7 returns to its deformation, pushing the clamping block 6 to return radially outwards, releasing the clamping fixation of the latex glove.
[0023] like Figures 1-2As shown, the device also includes: a laser 12, which is fixedly installed below one of the clamping plates 9; a receiver 13, which is fixedly installed on the lower part of the mounting bracket 2, with the laser 12 passing through it; the displacement of the clamping plate 9 will cause the laser 12 to move along its axial direction, and it will capture the positional changes of the laser beam in real time; and a central control panel 14, which is fixedly installed on the front side of the base 1 and electrically connected to the receiver 13, with a built-in data processing unit and display screen, which can receive the displacement data transmitted by the receiver 13 and display it intuitively.
[0024] Before testing, the control panel 14 presets the displacement reference range of the clamping plate 9 under qualified latex glove conditions. This range represents the stable position range that the clamping plate 9 should maintain after the latex glove is inflated under normal conditions. During testing, as the clamping plate 9 moves, the laser 12 follows the movement, and its emitted laser beam is received and recorded in real time by the receiver 13. The signal is then transmitted to the control panel 14. After comparing the results, if the latex glove's airtightness meets the standard and the internal air pressure is stable, the clamping plate 9 will remain in the reference position, and the laser displacement data recorded by the receiver 13 will always be within the preset range. The control panel 14 will then display "qualified." If the latex glove leaks air, its internal air pressure drops, and the laser displacement data recorded by the receiver 13 exceeds the preset range. The control panel 14 will then trigger a "unqualified" prompt. Therefore, by precisely quantifying the test structure through the laser 12 and receiver 13, the interference of subjective human factors on the test results will be eliminated, human error will be avoided, and the testing accuracy of this equipment will be improved. Furthermore, the automation level of this equipment will be enhanced, and labor costs will be reduced.
[0025] like Figures 1-2 As shown, this equipment also includes: a pressure sensor 15, fixedly installed in the middle section of the air inlet pipe 4, communicating with the inside of the air inlet pipe 4 and electrically connected to the central control console 14, used to monitor the gas pressure value delivered by the air pump to the latex glove in real time, and synchronously transmit the pressure data to the central control console 14, judging the sealing status between the latex glove and the connecting pipe 3 by pressure changes, avoiding misjudgment caused by sealing problems, reducing invalid testing processes, and improving the accuracy of test results; an indicator light 16, fixedly installed on the mounting bracket 2 and electrically connected to the central control console 14, used to intuitively provide feedback on the testing progress, allowing operators to quickly determine whether each piece of equipment needs intervention by observing the indicator light 16 from a distance, facilitating improved management efficiency in large-scale production scenarios, clarifying the testing rhythm, and avoiding misoperation during the testing process; and four sets of adjustable feet 17, fixedly installed at the four corners of the bottom of the base 1, used to adjust the overall level of the equipment, preventing the clamping plate 9 from being obstructed or unevenly stressed due to equipment tilt.
[0026] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
