Description

Technical Field

[0001] This utility model relates to the technical field of air-supported membrane punching equipment, and in particular to an air-supported membrane assembly device. Background Technology

[0002] In existing technologies, to improve the safety of intravenous infusions, filters are often installed on the infusion tubing to remove insoluble particles from the medication. The core material of the filter is the filter membrane. In current production processes, since filter membranes are generally in strip form and packaged in rolls, they are often mechanically punched after being unrolled to cut out filter sheets that fit the filter. Finally, the filter sheets are transferred and installed into the filter.

[0003] In order to improve the utilization rate of filter membrane rolls, i.e. to cut more filter membrane sheets from the filter membrane rolls, existing equipment often uses a translation punch to adjust the relative position of the punch and the filter membrane roll, thereby increasing the number of filter membrane sheets cut per unit area of ​​the filter membrane roll.

[0004] However, this punching mode often causes the punch to shift after a period of use, which in turn causes wear during punching. This results in poor punching performance and reduces the lifespan of the punch. Utility Model Content

[0016] This utility model can achieve the following beneficial effects: In a first aspect, this utility model provides an air-film assembly device, including a support mechanism, a film punching mechanism, a translation mechanism, and a feeding mechanism. The feeding mechanism is connected to the translation mechanism through the support mechanism and is used to feed material to the film punching mechanism. The film punching mechanism is provided with a plurality of punches spaced apart along a first direction. The distance between the centers of the cross-sections of adjacent punches is set as a unit spacing, and the unit spacing is greater than the cross-sectional diameter of the punch.

[0030] Example 1 This embodiment provides an air-film assembly device, referring to... Figure 1 and Figure 2 The air-film assembly device includes a support mechanism 1, a film punching mechanism 2, a translation mechanism 5, and a feeding mechanism 6. The feeding mechanism 6 is connected to the translation mechanism 5 through the support mechanism 1, and is used to feed material to the film punching mechanism 2. The film punching mechanism 2 is provided with a plurality of punches 23 spaced apart along a first direction. The distance between the centers of the cross-sections of adjacent punches 23 is set as a unit spacing, and the unit spacing is greater than the cross-sectional diameter of the punches 23. The film punching mechanism 2 is used to drive the plurality of punches 23 to simultaneously punch the film material conveyed by the feeding mechanism 6. The translation mechanism 5 is used to drive the support mechanism 1 to move toward or away from the first direction, and the moving stroke includes 0.25 times the unit spacing, 0.5 times the unit spacing, and 0.75 times the unit spacing.

[0031] This invention at least alleviates the technical problem in the prior art where adjusting the position of the cutter relative to the filter membrane roll by translating the cutter causes wear of the cutter due to deviation after a period of use.

[0032] In this embodiment of the invention, the air-film moving mechanism 3 is connected to the support mechanism 1, and the air-film moving mechanism 3 is used to drive the support mechanism 1 to move towards or away from the first direction. The feeding mechanism 6, which is connected to the support mechanism 1, can move synchronously with the support mechanism 1. The punching mechanism 2 is provided with a plurality of punches 23 spaced apart along the first direction. The plurality of punches 23 are spaced at the same distance, and the punches 23 are preferably circular cross-sections. The distance between the centers of the punches 23 is set as a unit spacing, that is, this unit spacing is the radius length of two punches plus the spacing between two punches. The translation mechanism 5 preferably includes an electric cylinder, and the driving distance of the electric cylinder can be 0.25 times the unit spacing, 0.5 times the unit spacing, and 0.75 times the unit spacing, that is, the punch located at the first end can perform punching at four positions: 0 times the unit spacing, 0.25 times the unit spacing, 0.5 times the unit spacing, and 0.75 times the unit spacing. The specific punching method includes: First, if the feeding mechanism 6 does not translate, the punch 23 at the first end punches at 0 unit spacing; second, if the feeding mechanism 6 translates by 0.5 unit spacing, the punch 23 at the first end punches at the center between the first end punch 23 and the adjacent punch 23; third, if the feeding mechanism 6 releases a certain length of film roll, the punch 23 at the first end translates to a position of 0.25 unit spacing and punches on one side of the midpoint between 0 unit spacing and 0.5 unit spacing; finally, the punch 23 moves from the position of 0.25 unit spacing to the position of 0.75 unit spacing and punches. In summary, the punch at the first end can have four punching positions.

[0033] Compared with the prior art, the air-film assembly device provided in this embodiment of the utility model drives the support mechanism 1 and the feeding mechanism 6 to move through the translation mechanism 5, so that the feeding mechanism 6 moves relative to the film-punching mechanism 2 in a first direction. Under the premise of satisfying the relative movement between the feeding mechanism 6 and the film-punching mechanism 2, the movement of the feeding mechanism 6 replaces the movement of the film-punching mechanism 2. The feeding mechanism 6 can move in four directions to meet the requirement of cutting as many air-film units as possible within a unit film roll length.

[0034] In an optional implementation of this embodiment, refer to Figure 2 and Figure 3 The support mechanism 1 includes a movable plate 11 and a support frame 12. The movable plate 11 is connected to the translation mechanism 5 and the support frame 12 is also connected to the moving plate 11. The support frame 12 is connected to the feeding mechanism 6.

[0035] Specifically: The top of the movable plate 11 is connected to the support frame 12. The support frame 12 includes a frame body with multiple support legs connected together. The support legs can be columns. The two ends of the support legs are detachably connected to the movable plate 11 and the frame body respectively by bolts. There can be four support legs. The support frame 12 is connected to the feeding mechanism 6 to realize the translation of the feeding mechanism 6.

[0036] Furthermore, referring to Figure 1 and Figure 2 The translation mechanism 5 includes a third driving member 51 and a third guide rail 52. The third guide rail 52 is distributed along the first direction and is slidably connected to the bottom slider of the moving plate 11. The third driving member 51 is provided with a limiting block 511, and the limiting block 511 has a slot. The moving plate 11 is provided with a connecting member 111, and the connecting member 111 is inserted into the slot of the limiting block 511. The third driving member 51 is used to drive the moving plate 11 to move toward or away from the first direction.

[0037] Specifically: two sets of third guide rails 52 can be provided at intervals, and both sets of third guide rails 52 are distributed along the first direction. The bottom of the moving plate 11 is provided with a corresponding slider, which is slidably connected to the corresponding third guide rail 52 through the slider. The third driving member 51 is provided with a limiting block 511. Correspondingly, the upper surface of the moving plate 11 is provided with a connecting member 111, which is connected to the limiting block 511, so as to realize that the limiting block 511 drives the connecting member 111 and the moving plate 11 to move along the third guide rail 52.

[0038] In an optional implementation of this embodiment, refer to Figure 4 The film punching mechanism 2 also includes a film punching drive 21, a connecting plate 22, and a material passing component 24. The film punching drive 21 is connected to a plurality of punches 23 through the connecting plate 22. The material passing component 24 is connected to the connecting plate 22. The material passing component 24 has a plurality of through holes spaced apart along a first direction, and the plurality of through holes are matched with the plurality of punches 23. The material passing component 24 has a channel for allowing film material to pass through. The film punching drive 21 is used to drive the punches 23 to insert into the corresponding through holes and punch the film material located in the channel during the insertion process.

[0039] Specifically: the film-punching drive unit 21 can be a pneumatic cylinder or an electric cylinder, and the output end of the film-punching drive unit 21 is located at its top and connected to the connecting plate 22; the connecting plate 22 is horizontally arranged and its top is provided with multiple punches 23 spaced apart along a first direction; the material passage member 24 can be connected to the connecting plate 22 and is located above the connecting plate 22. The material passage member 24 includes two overlapping plates, and there is a gap between the two plates to allow the film material to pass through. Both plates have multiple through holes, and the through holes of the two plates overlap and match the corresponding punches. In use, the multiple punches 23 simultaneously punch upward to punch holes in the film material, and during this punching process, the punches 23 are inserted into the corresponding through holes; each punch 23 has an air hole, which is used to connect to an air suction device so that after the air film is cut off, the air film can be adsorbed into the punch 23.

[0040] Furthermore, referring to Figure 4 The punching mechanism 2 also includes a baffle 25 and an air blowing pipe 26. The air blowing pipe 26 is distributed along the first direction and located on one side of the material passage member 24. The air blowing pipe 26 is used to blow away the air film remaining on the punch 23. The baffle 25 is disposed on the side of the material passage member 24 away from the air blowing pipe 26, and the baffle 25 is used to block the air film blown away by the air blowing pipe 26.

[0041] Specifically: both the baffle 25 and the air blowing pipe 26 are connected to the material passage 24, and the baffle 25 and the air blowing pipe 26 are located on both sides of the material passage 24. The air blowing pipe 26 is connected to an external air supply device, and the air blowing pipe 26 is distributed along the first direction and has multiple air outlets spaced apart. Correspondingly, the baffle 25 is a semi-enclosed baffle with multiple holes. In use, air is blown onto the punch 23 through the air blowing pipe 26 so that any air film that has not been removed is blown off the punch 23, preventing it from causing obstacles in the next punching process. The baffle 25 can prevent the blown air film from flying around.

[0042] In an optional implementation of this embodiment, refer to Figure 4 , Figure 5 and Figure 6 The feeding mechanism 6 includes a roller assembly 61, a pressure roller assembly 62, a feeding roller 63, a feeding roller group 64, a discharge roller group 65, and a drive assembly 66, all connected to the support frame 12. The roller assembly 61 is used to hold the roll of film material. The pressure roller assembly 62 is located on the side of the film material close to the roller assembly 61. The feeding roller 63 is used to guide the film material to the feeding roller group 64. The feeding roller group 64 and the discharge roller group 65 are respectively located on both sides of the film punching mechanism 2, and the feeding roller group 64 is used to convey the film material to the discharge roller group 65. The drive assembly 66 is connected to the feeding roller group 64 and the discharge roller group 65 respectively, and the drive assembly 66 is used to drive the feeding roller group 64 and the discharge roller group 65 to rotate in the same direction and at the same speed.

[0043] Specifically: The support frame 12 has a vertical plate for rotatably connecting to the roller assembly 61, on which a roll of film material is mounted. The feeding roller group 64 and the discharging roller group 65 are respectively located on both sides of the material passage member 24. The feeding roller group 64 includes a feeding roller and a first pressure roller, with film material passing between the feeding roller and the first pressure roller. Correspondingly, the discharging roller group 65 includes a discharging roller and a second pressure roller, with film material passing between the discharging roller and the second pressure roller. The drive assembly 66 is connected to both the feeding roller group 64 and the discharging roller group 65 to drive the feeding roller and the discharging roller to rotate at the same speed and in the same direction, thereby achieving the requirement of stable film material conveying. The pressure roller assembly 62 is located on the side of the film material closer to the roller assembly 61 to control the conveying of the film material, while the feeding roller 63 is used to change the feeding direction of the film material so that the film material can be conveyed horizontally to the feeding roller group 64.

[0044] Furthermore, referring to Figure 4 , Figure 5 and Figure 6 The feeding mechanism 6 also includes a brake assembly 67 and a reset mechanism 68, both of which are connected to the support frame 12. The pressure roller assembly 62 includes a pressure roller 621, a connecting arm 622, a rotating arm 623, and an elastic element 624. One end of the connecting arm 622 is connected to the tension spring 681 of the tension spring reset mechanism 68, and the connecting arm 622 is connected to the support frame 12 via a rotating shaft. The brake assembly 67 includes a belt 672, which is connected to the roller assembly 61, and the end of the belt 672 is connected to the connecting arm 622. One end of the rotating arm 623 is connected to the support frame 12 via a rotating shaft, and the rotating arm 623 is connected to the end of the connecting arm 622 away from the tension spring 681 via the elastic element 624. One end of the pressure roller 621 is connected to the end of the rotating arm 623 away from the rotating shaft, and the pressure roller 621 is located on the side of the film material close to the roller assembly 61.

[0045] Specifically, the roller assembly 61 includes a roller body 611, a roller 612, and a connecting rod 613. The roller 612 is rotatably connected to the support frame 12, and the roller 612 is connected to the roller body 611 via the connecting rod 613. The roller body 611 is used for winding the film roll. One end of the belt 672 is connected to the support frame 12 via a belt fixing block 671, and the free end of the belt 672 is in close contact with the roller 612, while the rear end is connected to the connecting arm 622. One end of the tension spring 681 is connected to the connecting arm 622, and the other end is connected to the support frame 12 via the connecting block 682. In use, the pressure roller 621 is pulled downward by the film material, and the pressure roller 621 drives the rotating arm 623 and the connecting arm 622 to rotate. At this time, the end of the connecting arm 622 connected to the tension spring 681 is lifted, so that the belt 672 separates from the roller 612. When the belt 672 is in close contact with the roller 612 again, the roller 612 is braked.

[0046] It should be noted that, referring to Figure 6 When the drive assembly 66 is activated, the film located at point B on the outside of the pressure roller 621 is stretched, thereby driving the pressure roller 621 to rotate. Because the pressure roller 621 has a certain rotation angle, its rotation compensates for the shortening of the film; at this time, the film movement does not require the feed roll on the connecting rod 613 to rotate immediately. When the pressure roller 621 rotates to an appropriate angle, the connecting arm 622 is driven by the elastic force of the elastic element 624 to overcome the tension of the tension spring 681, causing the connecting arm 622 to rotate upwards, thus slightly loosening the belt 672 from the tightly gripping roller assembly 61. This allows the feed roll on the connecting rod 613 to begin rotating instead of being locked. The pressure roller 621 continues to rotate or remains unchanged, while the feed roll on the connecting rod 613 also slowly rotates and releases material. The pressure roller 621 continues to rotate and collides hard with the connecting arm 622, driving the connecting arm 622 to move. The connecting rod 613 is then completely released, and the pulling resistance on the feed roll on the connecting rod 613 decreases. This avoids the situation where the connecting rod 613 is locked due to the direct pulling of the feed roll during the initial start-up of the drive assembly 66, causing the feed roll to be pulled hard and thus damaging or overstretching the film. In other words, it prevents hard pulling on the feed roll on the connecting rod 613 during the initial movement of the film by the drive assembly 66, thereby reducing the risk of film damage or overstretching.
