Description

Technical Field

[0001] The present invention relates to the technical field of air permeability detection, and particularly to an air permeability detection device for a dialysis paper cover material. Background Art

[0002] The dialysis paper cover material is a material used for medical device packaging. In order to ensure the safety and effectiveness of medical devices, an air permeability tester is needed to detect the air permeability of the dialysis paper cover material. When the dialysis paper cover material is processed and not yet cut, during the air permeability detection, it is necessary to detect different positions of a roll of dialysis paper cover material, so as to accurately evaluate the air permeability of the product. Therefore, during the detection process, after detecting one position, it is necessary to move the position of the sample, and then detect the next position. During the movement of the dialysis paper cover material, most of the movement is manually carried out. It is difficult to ensure that the moving distance is the same each time by manual movement. The inconsistent moving distance will cause uneven distribution of detection points. Some positions have too dense detection points, while some positions have sparse detection points. In this way, the obtained detection data cannot accurately reflect the overall air permeability of the dialysis paper cover material, and may exaggerate or underestimate the air permeability of some areas, resulting in a large deviation in the detection result.

Detailed implementation manners

[0027] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0028] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways than those specifically described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments. Embodiment 1

[0030] Refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 6 , which is the first embodiment of the present invention. This embodiment provides a device for detecting the air permeability of a dialysis paper cover material. The device for detecting the air permeability of a dialysis paper cover material includes a detection component 100, which includes a base 101. A support frame 102 is fixed on the top of the base 101. An upper pressing head 103 is arranged at the bottom of the support frame 102. A lower pressing head 104 is fixed on the top of the base 101.

[0031] When detecting the dialysis paper cover material, the sample is placed on the top of the lower pressing head 104, and then the upper pressing head 103 moves downward and presses the sample tightly. At this time, the air permeability can be detected. This is the prior art, and this solution will not be elaborated here, and those skilled in the art can clearly understand the working principle.

[0032] An auxiliary component 200 is arranged on the top of the base 101. It includes a pushing member 201. The pushing member 201 includes a support rod 201a. The support rod 201a is fixed on one side of the upper pressing head 103. A rotating sleeve 201b is arranged at the end of the support rod 201a. A rotating rod 201c is inserted into the rotating sleeve 201b. The bottom end of the rotating rod 201c is hinged to a pushing plate 201d through a hinge plate. A support plate 201e is fixed on the top of the base 101. A groove 201e-1 is opened on the support plate 201e. A clamping plate 201f is arranged in the groove 201e-1. A rotating column 201g is fixed on the rotating sleeve 201b. The rotating column 201g is movably connected inside the support rod 201a. The clamping plate 201f and the pushing plate 201d cooperate to clamp and fix the dialysis paper cover material, so as to drive the dialysis paper cover material to move.

[0033] The rotating rod 201c is movably connected inside the rotating sleeve 201b. The push plate 201d hangs down naturally and is in a horizontal state. The support plate 201e is used to support the dialysis paper cover material, and the height of the support plate 201e is lower than that of the pressing head 104. There are two clamping plates 201f, which are respectively located on both sides of the top of the support plate 201e.

[0034] The auxiliary component 200 further includes a rotating member 202. The rotating member 202 includes a rotating sleeve 202a. The rotating sleeve 202a is inserted into the clamping plate 201f. A first fixed shaft 202b is fixed inside the clamping plate 201f. A first spiral groove 202a-1 is formed on the rotating sleeve 202a. The first fixed shaft 202b slides inside the first spiral groove 202a-1. An activity column 202c is inserted into the rotating sleeve 202a. A second spiral groove 202c-1 is formed on the activity column 202c. A second fixed shaft 202d is fixed inside the rotating sleeve 202a. The second fixed shaft 202d slides inside the second spiral groove 202c-1.

[0035] The number of the rotating members 202 corresponds to that of the clamping plates 201f. A positioning hole 201d-1 is formed on the push plate 201d. The positioning hole 201d-1 cooperates with the top end of the activity column 202c. The top end of the activity column 202c and the positioning hole 201d-1 are both rectangular. A first spring 202f fixed to the bottom of the activity column 202c is used to apply an upward thrust to it. A fixed plate 202e fixed to the outside of the activity column 202c is used to cooperate with the push plate 201d to drive the activity column 202c to move downward.

[0036] When the upper pressing head 103 moves downward, it will drive the push plate 201d to move downward. At the same time, the positioning hole 201d-1 will be sleeved outside the activity column 202c. As the push plate 201d moves downward, it will contact the fixed plate 202e and push the fixed plate 202e to move downward. At this time, the fixed plate 202e will drive the activity column 202c to move downward and make the first fixed shaft 202b slide inside the first spiral groove 202a-1. Through the cooperation of the two, the rotating sleeve 202a is driven to rotate. At this time, the second fixed shaft 202d will slide inside the second spiral groove 202c-1, and the clamping plate 201f is driven to move upward through the cooperation of the two.

[0037] At the same time, the push plate 201d will contact the dialysis paper cover material and clamp and fix the dialysis paper cover material through the cooperation with the clamping plate 201f. As the upper pressing head 103 continues to move downward, the push plate 201d will tilt and drive the dialysis paper cover material to move through the cooperation with the clamping plate 201f. In this way, the detection position of the dialysis paper cover material can be switched, and the stability of the dialysis paper cover material during movement can be ensured, and the travel of each movement is the same. Thus, the detection points of the dialysis paper cover material can be evenly distributed, so as to avoid the situation that the detection results will deviate.

[0038] By moving the rotating rod 201c up and down within the rotating sleeve 201b, the height of the push plate 201d can be adjusted. In this way, the distance between the push plate 201d and the dialysis paper cover material to be detected below can be adjusted. Furthermore, the push plate 201d can contact the dialysis paper cover material earlier or later, and drive the dialysis paper cover material to move earlier or later. Since the descending stroke of the upper pressing head 103 is constant, the moving stroke of the dialysis paper cover material can be adjusted, so as to meet the detection requirements of different models of dialysis paper cover materials.

[0039] The auxiliary component 200 further includes a limiting member 206. The limiting member 206 includes a limiting post 206a. A chamber 201c-1 is formed on the rotating rod 201c. The limiting post 206a is located within the chamber 201c-1. A limiting hole 201b-1 is formed on the rotating sleeve 201b. The limiting post 206a is engaged with the limiting hole 201b-1. A fifth spring 206b is fixed to one end of the limiting post 206a. There are multiple positioning numbers of the limiting holes 201b-1, which are evenly distributed in a straight line on the rotating sleeve 201b. When the limiting post 206a is engaged with the limiting hole 201b-1, the position of the rotating rod 201c can be locked through their cooperation, thus avoiding the situation that the position adjustment of the rotating rod 201c changes. Through the arrangement of multiple limiting holes 201b-1, the rotating rod 201c can be locked at different positions. The fifth spring 206b is used to apply a thrust to the limiting post 206a. Embodiment 2

[0040] Refer to Figures 2 - 8 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment.

[0041] Specifically, the auxiliary component 200 further includes a positioning member 203. The positioning member 203 includes a support block 203a. The support block 203a is rotatably connected to the bottom of the rotating sleeve 202a through a bearing. A positioning post 203b is movably connected within the support block 203a. One side of the support plate 201e is fixed with a mounting block 203c. Both ends of the positioning post 203b are fixed to the two mounting blocks 203c respectively. One side of the support block 203a is fixed with a second spring 203d. The other end of the second spring 203d is fixed to the mounting block 203c.

[0042] The positioning post 203b is used to support and position the support block 203a. The support block 203a supports and positions the rotating sleeve 202a. And when the clamping plate 201f moves, it will drive the support block 203a to move through the rotating sleeve 202a, so as to avoid the situation that the clamping plate 201f deviates during movement.

[0043] When the push plate 201d moves upward and separates from the movable column 202c, the first spring 202f will push the movable column 202c upward. At this time, the clamping plate 201f will move downward and separate from the bottom of the head dialysis paper cover material. At this time, the support block 203a can be pushed to move in the reverse direction by the second spring 203d, and the clamping plate 201f can be moved to the initial position, and to prevent the clamping plate 201f from driving the dialysis paper cover material to move when moving in the reverse direction, which may cause the movement stroke of the dialysis paper cover material to change.

[0044] A stabilizing rod is fixed on one side of the support block 203a, and the top end of the stabilizing rod is movably connected inside the clamping plate 201f, which is used to position the clamping plate 201f to prevent the clamping plate 201f from shifting when moving up and down.

[0045] Specifically, the auxiliary assembly 200 further includes a locking member 205. The locking member 205 includes a stabilizing block 205a, which is fixed on one side of the support rod 201a. The insertion rod 205b is movably connected inside the stabilizing block 205a. A jack 201g-1 corresponding to the insertion rod 205b is provided on the rotating column 201g. One end of the insertion rod 205b is fixed with a connecting block 205c. A fourth spring 205d is fixed on one side of the connecting block 205c, and the other end of the fourth spring 205d is fixed to the stabilizing block 205a. An extrusion rod 205e is fixed at the bottom of the support frame 102. A force receiving groove 205b-1 corresponding to the extrusion rod 205e is provided on the insertion rod 205b, and the inner wall of the force receiving groove 205b-1 is inclined.

[0046] A torsion spring 205f is fixed on the outer side of the rotating column 201g, and the other end of the torsion spring 205f is fixed to the support rod 201a. A fixing column 205g is fixed at the bottom of the support rod 201a. The fixing column 205g is L-shaped, and the other end contacts the rotating sleeve 201b and supports the rotating sleeve 201b.

[0047] When the rotating sleeve 201b is tilted by a certain angle and stops rotating, at this time, the jack 201g-1 will coincide with the insertion rod 205b, and a pulling force will be applied to the connecting block 205c through the fourth spring 205d, so that the connecting block 205c drives the insertion rod 205b to engage with the jack 201g-1, and the angle of the rotating sleeve 201b can be locked through the cooperation of the two.

[0048] When the upper pressure head 103 drives the rotating sleeve 201b to move upward, the rotating sleeve 201b will maintain its current state and move upward in a translational manner, rather than resetting by rotating, so as to prevent the push plate 201d from not contacting the dialysis paper cover material after the upper pressure head 103 moves upward and not causing the position of the dialysis paper cover material to change.

[0049] After the upper punch 103 moves upward and resets, the bottom end of the extrusion rod 205e will extrude the inner wall slope of the force receiving groove 205b-1. Through the cooperation of the two, the insertion rod 205b is driven to separate from the insertion hole 201g-1, thereby releasing the restriction on the rotating column 201g. At this time, the rotating sleeve 201b can rotate downward under the action of the torsion spring 205f and its own gravity. And when the rotating sleeve 201b is about to rotate to the vertical state, it is restricted by the fixed column 205g, so that its final state is in a certain inclination, thereby avoiding the situation that the rotating sleeve 201b cannot rotate when moving downward, which will hinder the downward movement of the upper punch 103. Embodiment 3

[0050] Refer to Figures 1 - 8 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0051] Specifically, the auxiliary component 200 further includes a pressing member 204. The pressing member 204 includes a positioning plate 204a. The positioning plate 204a is fixed to one side of the upper punch 103. A fixing rod 204b is inserted into the positioning plate 204a. The bottom end of the fixing rod 204b is rotatably connected to a pressing wheel 204c through a rotating shaft. The top end of the fixing rod 204b is fixed with a fixing block 204d. A third spring 204e is fixed to the bottom of the fixing block 204d. The bottom end of the third spring 204e is fixed to the fixing rod 204b.

[0052] The fixing rod 204b is movably connected in the positioning plate 204a. When the upper punch 103 is about to press the dialysis paper cover material, the pressing wheel 204c will contact the dialysis paper cover material and apply a certain pressing force to the dialysis paper cover material. At this time, when the push plate 201d and the clamping plate 201f drive the dialysis paper cover material to move, the dialysis paper cover material will be subjected to a certain pulling force, so as to stretch the position of the dialysis paper cover material to be detected on the top of the lower punch 104 tightly, thereby avoiding the situation that the detection point of the dialysis paper cover material will be wrinkled, which will affect the detection accuracy.

[0053] Through the setting of the fixing block 204d and the third spring 204e, the pressing wheel 204c can have a certain elasticity when pressing the dialysis paper cover material, avoiding the situation that the pressing wheel 204c presses the dialysis paper cover material too tightly and tears the dialysis paper cover material. And the rotation of the pressing wheel 204c can further protect the dialysis paper cover material.

[0054] During use, the rolled dialysis paper cover is laid flat on the top of the support plate 201e. When the upper pressing head 103 moves downward, it will drive the push plate 201d to move downward. At the same time, the positioning hole 201d-1 will be sleeved outside the movable column 202c. As the push plate 201d moves downward, it will contact the fixed plate 202e and push the fixed plate 202e to move downward. At this time, the fixed plate 202e will drive the movable column 202c to move downward, and the first fixed shaft 202b will slide in the first spiral groove 202a-1. Through the cooperation of the two, the rotating sleeve 202a will be driven to rotate. At this time, the second fixed shaft 202d will slide in the second spiral groove 202c-1, and the clamping plate 201f will be driven to move upward through the cooperation of the two.

[0055] At the same time, the push plate 201d will contact the dialysis paper cover and clamp and fix the dialysis paper cover through the cooperation with the clamping plate 201f. As the upper pressing head 103 continues to move downward, the push plate 201d will tilt and drive the dialysis paper cover to move through the cooperation with the clamping plate 201f. In this way, the detection position of the dialysis paper cover can be switched, and the stability of the dialysis paper cover during movement can be ensured, and the travel of each movement is the same, so that the detection points of the dialysis paper cover can be evenly distributed, thus avoiding the deviation of the detection results.

[0056] When the upper pressing head 103 is about to press the dialysis paper cover, the pressing wheel 204c will contact the dialysis paper cover and apply a certain pressing force to the dialysis paper cover. At this time, when the push plate 201d and the clamping plate 201f drive the dialysis paper cover to move, the dialysis paper cover will be subjected to a certain pulling force, so that the position to be detected of the dialysis paper cover on the top of the lower pressing head 104 can be pulled tight, thus avoiding the situation that the detection points of the dialysis paper cover are wrinkled, which will affect the detection accuracy.

[0057] When detecting different models of dialysis paper covers and the travel of the sample needs to be adjusted, the rotating rod 201c moves up and down in the rotating sleeve 201b, and the height of the push plate 201d can be adjusted. In this way, the distance between the push plate 201d and the dialysis paper cover to be detected below can be adjusted, so that the push plate 201d can contact the dialysis paper cover earlier or later and drive the dialysis paper cover to move earlier or later. And because the travel of the upper pressing head 103 descending is constant, the travel of the dialysis paper cover can be adjusted to meet the detection requirements of different models of dialysis paper covers.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
