Description

TECHNICAL FIELD

[0001] The application is a kind of labor glove air permeability detection device and method, belongs to the technical field of detection. BACKGROUND

[0002] Labor gloves as the core equipment of labor protection system, its performance is directly related to the safety of operating personnel. In different industry operating scenes, the hands of operating personnel wearing labor gloves are easy to sweat. In order to protect the comfort of operating personnel and prevent gloves from sliding, air permeability detection has become a key link of labor glove production quality control. At present, the main air permeability detection methods mainly include the following two kinds: The first method is sampling cutting detection. This method needs to cut samples from different parts of labor gloves, and clamp them in the device with upper and lower cavities. During detection, vacuumize the lower end detection cavity first, then introduce auxiliary gas into the upper end cavity, synchronously collect the gas data of the upper and lower cavities and compare and calculate, and finally obtain the final air permeability data through the detection of multiple samples. However, this method has long detection cycle, low efficiency, and can damage the integrity of the gloves. The second method is whole sealing detection. This method clamps the labor gloves on the gas inlet and tightens, seals after putting into the detection tank, vacuums, introduces auxiliary gas into the gloves, collects the gas data in the gas inlet and the detection tank, and analyzes and calculates to obtain the air permeability result. This method has fast detection speed, high efficiency, and can preserve the integrity of the gloves. However, some labor gloves have plastic coating on the palm, and the air permeability of different areas of these gloves is different: the air permeability of the coated part is poor, and the air permeability of the uncoated part is high. In the whole detection, auxiliary gas is easy to overflow from the uncoated part first, and the air permeability data of the coated part cannot be effectively detected, resulting in deviation of the collected data. If the first method is used for detection, the work efficiency is poor, which affects the detection effect and actual use quality of labor gloves. SUMMARY

[0018] Embodiment two: as shown in Figure 4 、 Figure 5 、 Figure 7 and Figure 8 , the two annular barrels 54 arranged oppositely are respectively communicated and installed on the inward end of the two detection barrels 5, the annular barrel 54 provides an installation carrier for the annular outer rubber pad 542 and other components, and the annular outer rubber pad 542 located outside the through hole 11 is arranged on the inward end of the annular barrel 54, and the annular inner rubber pad 545 located inside the annular outer rubber pad 542 is installed on the inward end of the annular barrel 54, and the annular inner rubber pad 545 is used in cooperation with the annular outer rubber pad 542 to protect the labor protection glove to be detected; The annular inner wall of the annular outer rubber pad 542 and the annular outer end of the annular inner rubber pad 545 are chamfered, and the chamfering provides a deformation space for the annular air bag 541. The annular plate 543 is slidingly connected in the annular cylinder 54, and the annular plate 543 provides a mounting carrier for the annular air bag 541. A plurality of second elastic members 544 are equidistantly arranged between the outward end of the annular plate 543 and the outward wall of the inner part of the annular cylinder 54. The plurality of second elastic members 544 are used in cooperation to apply pressure to the annular air bag 541. The second elastic member 544 can be a spring.

[0019] In use, first, the labor protection gloves to be detected are sleeved on the hand mold 2, and then the hand mold 2 and the sleeved labor protection gloves to be detected are extended to a suitable position below the through hole 11 by using the first electric push rod 4, the hollow rod 3, and the connecting cylinder 31.

The second collector on the air pipe 34 detects the information data of the auxiliary gas in the corresponding air pipe 34 and transmits the data to the controller 13. At the same time, the two second electric push rods 51 and two pistons 52 are used to form a detection space in the detection cylinder 5 at the inner end of the piston 52 and to form a negative pressure in the detection space. Under the assistance of the negative pressure, some of the auxiliary gas in the groove 35 will pass through the work gloves and enter the detection space. At this time, the first collector 53 collects information data of the auxiliary gas in the detection space and transmits the data to the controller 13. Then, the controller 13 compares, analyzes and calculates the corresponding data in pairs to obtain the breathability test results of the palm and back of the hand of the work gloves.

Two first rubber plates 114 located at the lower ends of the second rubber plates 115 are respectively set on the inner ends of the two clamping plates 111. The first rubber plates 114 provide a processing carrier for the V-groove 116. Multiple V-shaped grooves 116, arranged in a narrow-at-the-top and wide-at-the-bottom pattern, are formed by recessing the inner end of the first rubber plate 114 outward. The work gloves fitted on the hand mold 2 are unfolded through the V-shaped grooves 116. The two first elastic elements 113, which are located on the outer side of the two round rods 112 and whose other ends are connected to the inner wall of the through hole 11, are symmetrically installed on the outer end of the clamping plate 111. The first elastic elements 113 apply an inward pushing force to the corresponding clamping plate 111. The first elastic elements 113 can be springs.

[0021] In use, first, the labor protection gloves to be detected are sleeved on the hand mold 2, and then the first electric push rod 4, the hollow rod 3 and the connecting cylinder 31 are used to make the hand mold 2 and the sleeved labor protection gloves to be detected move downward and be inserted into the V-shaped cavity formed by the two clamping plates 111, and the hand mold 2 and the sleeved labor protection gloves to be detected continue to move downward, thereby making the two clamping plates 111 and other components move outward and compress the first elastic member 113, so that the first elastic member 113 generates elastic force, and the hand mold 2 and other components enter between the two first rubber plates 114 under the guidance of the second rubber plate 115; At this time, the two first rubber plates 114 and the corresponding plurality of V-shaped grooves 116 respectively move the left and right ends of the labor protection gloves to be detected, thereby unfolding the labor protection gloves to be detected upward and outward, and then the hand mold 2 and the sleeved labor protection gloves to be detected are extended to the appropriate position below the through hole 11, so as to arrange the left and right ends of the sleeved labor protection gloves to be detected, effectively reduce the probability of wrinkles in the detection of the labor protection gloves, effectively reduce the error probability, and effectively ensure the detection effect and use quality.
