Description

Technical Field

[0001] This invention relates to a device and method for testing the breathability of work gloves, belonging to the field of testing technology. Background Technology

[0002] As a core piece of equipment in the occupational safety and health protection system, the performance of work gloves directly affects the safety of workers. In various industry work scenarios, workers' hands tend to sweat when wearing full-body work gloves. To ensure worker comfort and prevent gloves from slipping, breathability testing has become a crucial aspect of quality control in work glove production. Currently, the two main methods for testing breathability are as follows: The first method is sampling and cutting testing. This method requires cutting samples from different parts of the work gloves and clamping them in a device with upper and lower cavities. During testing, the lower testing cavity is first evacuated, and then auxiliary gas is introduced into the upper cavity. Gas data from both cavities are collected simultaneously and compared for calculation. The final air permeability data is obtained by testing multiple samples. However, this method has a long testing cycle, low efficiency, and can damage the integrity of the gloves. The second method is overall seal testing. This method involves placing the opening of the work gloves over the air inlet and clamping it tightly. After being placed in a testing container and sealed, a vacuum is drawn, and auxiliary gas is introduced into the gloves. Data on the gas flow path and the gas inside the testing container is collected and analyzed to determine the air permeability. This method is fast, efficient, and preserves the integrity of the gloves. However, some work gloves have plastic coating on the palm area. The air permeability of these gloves varies between different areas: the coated areas have poor air permeability, while the uncoated areas have high air permeability. During overall testing, the auxiliary gas tends to leak out preferentially from the uncoated areas, and the air permeability data of the coated areas cannot be effectively detected, leading to data inaccuracies. Using the first method for testing would result in poor work efficiency, thus affecting the testing results and the actual quality of the work gloves in use. Summary of the Invention

The multiple air holes are arranged in an annular structure and are located on the outside of the telescopic device.

[0006] Furthermore, the driving component includes a frame, which is installed at the lower end of the platform and is located outside the through hole. The cross-section of the frame is inverted U-shaped, and the lower ends of the two vertical parts of the frame are provided with arc-shaped grooves, which fit against the upper outer end of the detection cylinder. A lead screw is rotatably connected between the two vertical parts of the frame. The outer end of the lead screw is connected to a slider through a ball nut pair, and the slider is installed on the upper end of the detection cylinder. A drive device is provided at the outer end of the frame, and the output shaft of the drive device is connected to the lead screw.

[0007] Furthermore, the lifting inflatable component includes a lifting device, which is installed in the middle of the rear end of the platform.

[0008] Furthermore, the connecting component includes a connecting cylinder, which is installed at the lower end of the front transverse portion of the hollow rod.

[0011] A method for testing the breathability of work gloves, using the aforementioned work gloves breathability testing device, includes the following steps: Step 1: Loading materials – fitting the work gloves to be tested onto the hand mold; The second step is pre-processing. Using the lifting equipment and hollow rod, the hand mold and the work gloves to be tested are moved down and passed through the through hole, so that the hand mold and the work gloves to be tested extend to a suitable position under the table. The third step is clamping. Two driving devices, two lead screws and two sliders are used to move the two detection cylinders inward, so that the two detection cylinders make squeezing contact with the left and right ends of the work gloves to be tested, thereby clamping the work gloves to be tested. At this time, the groove is located inside the detection cylinder, and the two pistons are respectively attached to the left and right ends of the work gloves to be tested.

Two second collectors collect data on the auxiliary gas from the two air tubes. Simultaneously, two telescopic devices move two pistons outward along the two detection cylinders, creating a space within the detection cylinders at the piston's inward end. The auxiliary gas in the grooves passes through the work gloves under test and enters the corresponding space. The corresponding first collector collects data on the auxiliary gas within this space. The collected data is then analyzed, compared, and calculated to complete the air permeability test of the left and right ends of the work gloves.

[0012] The beneficial effects of this invention are: The hand mold is used to inflate the work gloves to be tested. Then, using the first electric push rod, hollow rod, connecting cylinder, and hand mold, the work gloves are lowered and extended to a suitable position below the through hole. Two servo motors, two lead screws, and two sliders are then used to move the two detection cylinders inward, making them press against the left and right ends of the work gloves. Assist gas is then supplied to the two grooves using the detection body, connecting tube, hollow rod, and two air tubes. At this time, the second collector on the air tube detects the information data of the assist gas in the corresponding air tube. Simultaneously, using the two second electric push rods and two pistons, detection spaces are formed in both detection cylinders. The first collector then collects the information data of the assist gas in the detection spaces. Then, the corresponding data are compared, analyzed, and calculated to obtain the breathability test results for the palm and back of the hand of the work gloves. This enables simultaneous two-point testing of work gloves, effectively reducing the probability of errors during testing, improving work efficiency and accuracy, and ensuring testing results and usage quality. At the same time, it achieves linkage between testing and clamping operations, further improving work efficiency. It also allows for adjustment of the testing space as the testing process progresses, and linkage between the testing space and the testing operation, thereby avoiding the pre-treatment process of vacuuming and air replenishment of the testing space. This effectively reduces the probability of damage to work gloves during pre-treatment, effectively reduces the probability of deviations during testing, and effectively ensures testing results and usage quality.

[0015] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0016] Example 1: As Figures 1-7As shown, a device for testing the breathability of work gloves is provided, including: a platform 1, with a through hole 11 formed by a downward recess on the upper surface of the platform 1, through which a hand mold 2 passes through the platform 1, and a fixed part of a lifting device is installed on the middle of the rear end of the platform 1. The lifting device drives the hollow rod 3 to move up and down. The lifting device can be a first electric push rod 4, and the lower end of the rear transverse part of the Z-shaped hollow rod 3 is connected to the upper end of the movable part of the lifting device. The hollow rod 3 provides a mounting carrier for components such as the connecting cylinder 31. A guide rod 32, which passes through the platform 1 and is slidably connected to the platform 1, is installed on the lower end of the rear transverse part of the hollow rod 3. The guide rod 32 guides the up and down movement of the hollow rod 3. A connecting cylinder 31 is installed on the lower end of the front transverse part of the hollow rod 3. The connecting cylinder 31 provides a mounting carrier for the hand mold 2. The hand mold 2, which is located directly above the through hole 11, is placed on the lower end of the connecting cylinder 31. The hand mold 2 provides a mounting carrier for the work gloves to be tested. Grooves 35 are formed by indenting the left and right ends of the palm of the hand mold 2. The grooves 35 provide auxiliary space for detection. Two air pipes 34, which pass through the connecting tube 31 and have their other ends set at the upper end of the hand mold 2, are symmetrically connected and installed on the lower end of the front horizontal part of the hollow rod 3. The other ends of the two air pipes 34 pass through the hand mold 2 and are respectively connected to the inward ends of the two grooves 35. The hollow rod 3 is connected to the grooves 35 through the air pipes 34. Two second collectors are respectively installed on the two air pipes 34. The second collectors collect information data of the auxiliary gas flowing in the air pipes 34. The other end of the connecting pipe 33 is connected to the detection body 14 and installed on the rear end of the hollow rod 3. The auxiliary gas is delivered into the hollow rod 3 through the connecting pipe 33. Two inverted U-shaped frame bodies 56 located on the left and right sides of the through hole 11 are symmetrically installed on the lower end of the platform 1. The frame bodies 56 provide a mounting carrier for components such as lead screws 55. The two lead screws 55 are rotatably connected between the two vertical parts of the two frame bodies 56. The lead screws 55 cause the sliders 57 to move. The two sliders 57 are then installed on the outer ends of the two lead screws 55 through ball nut pairs. The sliders 57 cause the detection cylinder 5 to move. The fixed parts of the two drive devices, whose output shafts are respectively connected to the two lead screws 55, are respectively set on the outward ends of the two frames 56. The lead screws 55 are driven to rotate by the drive devices. The drive devices can be servo motors 58. The two detection cylinders 5, which are arranged opposite to each other, are respectively installed at the lower ends of the two sliders 57. The two detection cylinders 5 work together to clamp the work gloves to be tested and to provide a space for breathability testing. Arc-shaped grooves that fit the upper outer ends of the detection cylinders 5 are opened at the lower ends of the two vertical parts of the frame 56. The movement of the detection cylinders 5 is guided by the arc-shaped grooves. The detection body 14, located between the lifting device and the guide rod 32 and inside the frame 12, is installed on the lower end of the platform 1. Assist gas is delivered outward through the detection body 14. The controller 13, located between the lifting device and the guide rod 32 and on the lower side of the hollow rod 3, is installed on the upper end of the platform 1. The controller 13 is electrically connected to the detection body 14, the lifting device, the drive device, the telescopic device, the first collector 53, and the second collector. Through the controller 13, the relevant electronic equipment can be controlled to start and stop, and the collected data can be analyzed, compared, calculated, and displayed. The frame 12 is installed on the lower end of the platform 1, and the through hole 11, the detection cylinder 5, the guide rod 32 and the telescopic device are all located on the outside of the frame 12. The platform 1 is lifted by the frame 12. Multiple air holes 59 arranged in a ring structure are formed inward on the outer end of the detection cylinder 5, located on the outside of the telescopic device and extending to the inner wall of the detection cylinder 5. The multiple air holes 59 are used in conjunction to maintain pressure inside the detection cylinder 5. Two pistons 52, which pass through the annular cylinder 54 and extend into the annular inner rubber pad 545, are slidably connected to the two detection cylinders 5. Through the pistons 52, a detection space can be formed in the detection cylinder 5. The fixed parts of two telescopic devices, whose movable parts pass through the two detection cylinders 5 and are respectively connected to the two pistons 52, are respectively installed on the outward ends of the two detection cylinders 5. The telescopic devices drive the pistons 52 to move. The telescopic devices can be second electric push rods 51. Then, two first collectors 53, whose two inward end faces coincide with the inward end faces of the pistons 52, are respectively embedded on the inward ends of the two pistons 52. The first collectors 53 are used to collect information data in the detection space.

[0017] In use, the work gloves to be tested are first put onto the hand mold 2 to expand them. Then, the first electric push rod 4 is activated to drive the hollow rod 3 to move downward, which in turn moves the connecting cylinder 31 downward. This causes the hand mold 2 and the work gloves to be tested to move downward and insert into the through hole 11, so that the hand mold 2 and the work gloves to be tested extend to the lower side of the through hole 11 to a suitable position. Then, the two servo motors 58 are activated to drive the two lead screws 55 to rotate. Since the lead screws 55 and the sliders 57 are connected by ball nuts, the rotation of the two lead screws 55 causes the two sliders 57 to move inward, which in turn causes the two testing cylinders 5 to move inward and make squeezing contact with the left and right ends of the work gloves to be tested on the hand mold 2. At this time, the two grooves 35 on the hand mold 2 are located in the two testing cylinders 5 respectively, and the two pistons 52 are respectively attached to the left and right ends of the work gloves to be tested. Then, auxiliary gas is delivered into the hollow rod 3 using the detection body 14 and the connecting pipe 33. The auxiliary gas in the hollow rod 3 is then diverted into two air pipes 34. At this time, 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. Then, the auxiliary gas in the two air pipes 34 is delivered into the corresponding two grooves 35. At the same time, the two second electric push rods 51 are activated, thereby driving the two pistons 52 to move outward along the corresponding two detection cylinders 5. This creates a detection space in the detection cylinder 5 located at the inner end of the piston 52, and creates 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. This realizes the synchronous dual-point detection operation of the work gloves, effectively reducing the probability of errors in the detection, improving work efficiency and accuracy, and effectively ensuring the detection effect and the quality of use. Simultaneously, it achieves linkage between the inspection and clamping operations, further improving work efficiency. It also enables the inspection space to be adjusted as the inspection process progresses, and links the inspection space with the inspection operation, thereby avoiding the pre-treatment process of vacuuming and gas replenishment of the inspection space. This effectively reduces the probability of damage to work gloves during pre-treatment, effectively reduces the probability of deviations during inspection, and effectively ensures the inspection effect and usage quality.

[0018] Example 2: Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, two annular cylinders 54 arranged opposite to each other are connected and installed on the inner ends of the two detection cylinders 5. The annular cylinders 54 provide a mounting carrier for components such as the annular outer rubber pad 542. The annular outer rubber pad 542 located outside the through hole 11 is set on the inner end of the annular cylinder 54. Then, the annular inner rubber pad 545 located inside the annular outer rubber pad 542 is installed on the inner end of the annular cylinder 54. The annular inner rubber pad 545 and the annular outer rubber pad 542 are used together to protect the work gloves to be tested. Chamfers are formed on the inner wall of the annular outer rubber pad 542 and the outer end of the annular inner rubber pad 545. The chamfers provide deformation space for the annular airbag 541. The annular plate 543 is slidably connected inside the annular cylinder 54. The annular plate 543 provides a mounting carrier for the annular airbag 541. Multiple second elastic elements 544 are equidistantly arranged between the outer end of the annular plate 543 and the outer wall of the inner side of the annular cylinder 54. The multiple second elastic elements 544 work together to apply pressure to the annular airbag 541. Springs can be used for the second elastic elements 544. The annular airbag 541, which extends outward from the annular cylinder 54 and passes between the annular outer rubber pad 542 and the annular inner rubber pad 545, is then installed on the inner end of the annular plate 543. The annular airbag 541 fills and seals the textile pores in the work gloves.

[0019] In use, the work gloves to be tested are first put onto the hand mold 2. Then, the first electric push rod 4, the hollow rod 3 and the connecting cylinder 31 are used to extend the hand mold 2 and the work gloves to be tested to the lower side of the through hole 11 to a suitable position. Then, the two servo motors 58, the two lead screws 55 and the two sliders 57 are used to move inward, thereby moving the two detection cylinders 5 inward, thereby moving the two annular cylinders 54 and other components inward. Then, the two annular airbags 541 first contact the left and right ends of the work gloves respectively. Then, the two detection cylinders 5 continue to move inward. At this time, the annular airbags 541 will be subjected to outward pressure. Under the action of pressure, the annular airbags 541 will contract into the space formed by the annular outer rubber pad 542 and the annular inner rubber pad 545. Simultaneously, the outer annular rubber pad 542 and the inner annular rubber pad 545 will contact the side of the work glove. Then, the detection cylinder 5 continues to move inward, causing the outer annular rubber pad 542, the inner annular rubber pad 545, and the annular airbag 541 to be subjected to outward pressure. This causes the annular plate 543 to move outward along the corresponding annular cylinder 54, thereby compressing multiple second elastic elements 544 and generating elastic force in the second elastic elements 544. Under the action of the elastic force of the second elastic elements 544, an inward squeezing force is applied to the annular airbag 541. Under the combined action of outward pressure and inward squeezing force, the annular airbag 541 will contract and deform. The deformed annular airbag 541 will fill the pores formed on the work glove by the textile, thereby using the annular airbag 541 to fill the pores on the work glove, effectively reducing the probability of leakage during the inspection, further reducing the probability of errors during the inspection, and effectively ensuring the inspection effect and the quality of use. At this time, the two detection cylinders 5 are respectively sealed and connected to the left and right ends of the work gloves to be tested. Then, the detection body 14, connecting pipe 33, hollow rod 3 and two air pipes 34 are used to deliver the gas into the two grooves 35 in a diversion manner. 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.

[0020] Example 3: Figures 9-11 As shown, the through hole 11 has a rectangular cross-section. Two trapezoidal clamping plates 111 with narrower upper and wider lower cross-sections are symmetrically and movably installed in the through hole 11. The clamping plates 111 provide a mounting carrier for components such as the first rubber plate 114. Two round rods 112 that penetrate the two clamping plates 111 are symmetrically arranged in the through hole 11. The two round rods 112 are located on the front and rear sides of the hand mold 2. The two round rods 112 work together to guide the movement of the clamping plates 111. Two triangular cross-section second rubber plates 115 are respectively installed on the inner ends of two clamping plates 111, with the inclined surfaces of the second rubber plates 115 overlapping the inclined surfaces of the corresponding clamping plates 111. The second rubber plates 115 are located on the lower side of the round rod 112. The second rubber plates 115 guide the hand mold 2 and the suit of work gloves to be tested to move downwards. 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, the work gloves to be tested are first put onto the hand mold 2. Then, the first electric push rod 4, the hollow rod 3 and the connecting tube 31 are used to move the hand mold 2 and the work gloves to be tested downward and insert them into the V-shaped cavity formed by the two clamping plates 111. The hand mold 2 and other components continue to move downward, thereby causing the two clamping plates 111 and other components to move outward and compress the first elastic element 113, so that the first elastic element 113 generates elastic force. At the same time, under the guidance of the second rubber plate 115, the hand mold 2 and other components enter between the two first rubber plates 114. At this time, the two first rubber plates 114 and the corresponding multiple V-shaped grooves 116 move relative to each other on the left and right ends of the work gloves to be tested, thereby unfolding the work gloves to be tested upward and outward, and then extending the hand mold 2 and the set of work gloves to be tested to the appropriate position under the through hole 11, so as to tidy up the left and right ends of the set of work gloves to be tested, effectively reducing the probability of wrinkles appearing at the testing position of the work gloves during testing, effectively reducing the probability of errors, and effectively ensuring the testing effect and the quality of use; Then, using two servo motors 58, two lead screws 55, and two sliders 57, the two detection cylinders 5 move inward and make squeezing contact with the left and right ends of the work gloves to be tested on the hand mold 2. At this time, the two grooves 35 on the hand mold 2 are located in the two detection cylinders 5 respectively. Then, using the detection body 14, connecting pipe 33, hollow rod 3, and two air pipes 34, auxiliary gas is delivered to the two grooves 35 in a split manner. At this time, the second collector on the air pipe 34 detects the information data of the auxiliary gas in the corresponding air pipe 34. At the same time, using two second electric push rods 51 and two pistons 52, a detection space is formed in the detection cylinder 5, and a negative pressure is formed in the detection space. Under the assistance of the negative pressure, some of the auxiliary gas in the grooves 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.

[0022] A method for testing the breathability of work gloves, using the aforementioned work gloves breathability testing device, includes the following steps: Step 1: Loading materials, fitting the work gloves to be tested onto hand mold 2; The second step is pre-processing. Using the first electric push rod 4 and the hollow rod 3, the hand mold 2 and the work gloves to be tested are moved down and pass through the through hole 11, thereby allowing the hand mold 2 and the work gloves to be tested to extend to a suitable position under the table 1. The third step is clamping. Two servo motors 58, two lead screws 55 and two sliders 57 are used to move the two detection cylinders 5 inward, so that the two detection cylinders 5 make squeezing contact with the left and right ends of the work gloves to be tested, thereby clamping the work gloves to be tested. At this time, the groove 35 is located inside the detection cylinder 5, and the two pistons 52 are respectively attached to the left and right ends of the work gloves to be tested. The fourth step is testing. Auxiliary gas is supplied to the hollow rod 3 using the connecting pipe 33. Then, the auxiliary gas in the hollow rod 3 is diverted to two grooves 35 using two air pipes 34. At this time, two second collectors collect the information data of the auxiliary gas in the two air pipes 34. Simultaneously, two second electric push rods 51 cause two pistons 52 to move outward along the two detection cylinders 5, creating a space inside the detection cylinder 5 at the inward end of the pistons 52. The auxiliary gas in the groove 35 passes through the work gloves to be tested and enters the corresponding space. The corresponding first collector 53 collects the information data of the auxiliary gas in the space. The collected data is then analyzed, compared, and calculated to complete the air permeability test of the left and right ends of the work gloves.
