Description

Technical Field

[0001] This utility model relates to the field of medical product processing technology, and in particular to a device for positioning the easy-tear opening of sterile dressing individual packaging. Background Technology

[0002] In the medical field, sterile dressings are critical consumables that come into direct contact with wounds, and the sterility and ease of opening of their packaging directly affect the safety and efficiency of clinical use. Individually packaged dressings must form a sterile barrier through strict sealing, while also featuring easy-tear openings to ensure that medical personnel can quickly open them in emergency situations, avoiding delays in treatment or secondary contamination due to difficulty in opening. Therefore, positioning devices are needed to secure the individual packaging of sterile dressings, and then processing devices are used to create easy-tear openings.

[0003] Existing easy-tear positioning devices for sterile dressing packaging typically fix the packaging material or semi-finished product at the processing station. A fixed positioning baffle limits the edge of the material to determine its lateral position, and then the cutting blade cuts at the preset longitudinal position to form an easy-tear opening. However, the waste material left after processing is left on the processing table, which is inconvenient to handle. After multiple uses, it needs to be cleaned manually, which affects the processing efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an easy-tear positioning device for individual packaging of sterile dressings, which aims to improve the problem that the existing easy-tear positioning device for individual packaging of sterile dressings is inconvenient to handle waste materials after processing, thus affecting processing efficiency.

[0006] The above technical solution involves installing a rack on the outer wall of the mounting base where the cutting machine is installed. When the cutting machine slides longitudinally to perform cutting, the rack drives the large gear to rotate, which in turn drives the small gear to rotate faster. The synchronous pulley and synchronous belt then transmit the power of the small gear to the drive rod, thereby driving the fan to operate and blowing the packaging bag waste generated during cutting into the collection trough at the rear end, achieving an automatic cleaning effect and improving processing efficiency.

[0007] Preferably, the clamping assembly includes a processing table, which is disposed on the top outer wall of the base. The inner wall of the processing table is provided with a plurality of springs, one end of each spring is fixedly connected to the inner wall of the processing table, and the other end of each spring is fixedly connected to one end of a connecting rod.

[0011] Preferably, the outer wall of the support base is provided with an installation groove, the fan is installed on the inner wall of the installation groove, the fan is located on one side of the processing table, and the collection groove is located on the other side of the processing table.

[0012] Preferably, the upper surface of the processing table is provided with multiple sliding grooves, the clamping block is slidably connected to the inner wall of the sliding groove, and the outer wall of the clamping block is equipped with a protective pad.

[0013] Preferably, the inner wall of the base is rotatably connected to a worm gear and a main shaft, one of the handwheels is fixedly connected to the outer wall of the worm gear, the outer wall of the main shaft is fixedly connected to a worm wheel, the teeth of the worm gear and the worm wheel are meshed, and the main shaft is fixedly connected to the outer wall of the processing table.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the rack slides synchronously when the mounting base is raised and lowered.

[0027] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0028] Reference Figures 1-3 This utility model provides an embodiment of an easy-tear positioning device for individually packaged sterile dressings, comprising a base 1, a support seat 2 and a collection groove 19 fixedly connected to the outer wall of the base 1, a telescopic rod 3 fixedly connected to the outer wall of the support seat 2, a mounting seat 4 fixedly connected to the output end of the telescopic rod 3, a rack 12 fixedly connected to the outer wall of the mounting seat 4, a large gear 13, a rotating shaft 14 and a drive rod 16 rotatably connected to the inner wall of the support seat 2, a small gear 15 fixedly connected to the outer wall of the rotating shaft 14, a fan 17 fixedly connected to the outer wall of the drive rod 16, synchronous pulleys 18 fixedly connected to the outer walls of both the rotating shaft 14 and the drive rod 16, a synchronous belt sleeved on the outer wall of the synchronous pulleys 18, and a clamping assembly provided at the top of the base 1. A support plate 9 is fixedly connected to the inner wall of the support base 2. A sliding rod 10 is fixedly connected to the inner wall of the support base 2 and the outer wall of the support plate 9 on opposite sides. Multiple limiting rods 11 are fixedly connected to the outer walls of the base 1 and the support base 2 on opposite sides. The inner wall of the mounting base 4 is slidably connected to the outer walls of the sliding rod 10 and the limiting rods 11. A limiting groove is opened on the outer wall of the support base 2. The outer wall of the mounting base 4 is slidably connected to the inner wall of the limiting groove. The tooth ends of the rack 12 and the large gear 13 are meshed. The tooth ends of the large gear 13 and the small gear 15 are meshed. An installation groove is opened on the outer wall of the support base 2. The fan 17 is installed on the inner wall of the installation groove. The fan 17 is located on one side of the processing table 20. The collection groove 19 is located on the other side of the processing table 20.

[0029] Specifically, base 1 provides support for all components, and support base 2 provides support for the installation of telescopic rod 3. When the telescopic rod 3 drives the mounting base 4 and the cutting machine 6 to adjust their longitudinal position for processing, the rack 12 installed on the outer wall of the mounting base 4 will mesh with the large gear 13 inside the support base 2 to rotate. The sliding of the mounting base 4 is limited and supported by the limiting groove, the slide rod 10, and the limiting rod 11. After meshing again, the large gear 13 drives the small gear 15 and the rotating shaft with the synchronous pulley 18 installed. When shaft 14 rotates, since the gear ratio of large gear 13 and small gear 15 is set to N:1, when large gear 13 rotates once, small gear 15 will rotate N times, thus amplifying the rotational force. This drives shaft 14 to rotate at high speed, and through synchronous pulley 18, drives drive rod 16 to rotate synchronously, thereby driving fan 17 to rotate at high speed. This blows air onto the packaging bags placed on the front processing table 20, causing the cut waste to be blown into the collection trough 19 in front and collected, eliminating the need for subsequent manual cleaning and improving processing efficiency.

[0030] Reference Figure 4 and Figure 5The clamping assembly includes a processing table 20, which is set on the top outer wall of the base 1. The inner wall of the processing table 20 is provided with multiple springs 21. One end of the spring 21 is fixedly connected to the inner wall of the processing table 20, and the other end of the spring 21 is fixedly connected to one end of a connecting rod 22. The other end of the connecting rod 22 is fixedly connected to a clamping block 23. Multiple sliding grooves are opened on the upper surface of the processing table 20. The clamping block 23 is slidably connected to the inner wall of the sliding groove. A protective pad is installed on the outer wall of the clamping block 23.

[0031] Specifically, the clamping component is normally hidden in a groove on the upper surface of the processing table 20. When an individual package is placed on the processing table 20, the clamping block 23 is rotated out of the groove and pulled outward, causing the spring 21 to deform. The elastic force of the spring 21 is used to clamp the package bag, keeping it stable during processing. The elastic force of the spring 21 can also be used to clamp packages of different sizes, improving the applicability of the device. The protective pad installed on the clamping block 23 prevents the clamping from damaging or abrading the surface of the package bag. At the same time, threads are added to the surface of the processing table 20 to increase the friction between the surface and the package bag, further maintaining the stability of the package bag during processing.

[0032] Reference Figure 1 and Figure 2 The inner wall of the mounting base 4 is rotatably connected to and passes through a lead screw 7. The outer wall of the lead screw 7 is fixedly connected to a handwheel 8. The outer wall of the lead screw 7 is threadedly connected to a slider 5. A cutting machine 6 is installed at the bottom of the slider 5.

[0033] Specifically, a lead screw 7 rotates on the inner wall of the mounting base 4. One end of the lead screw 7 passes through the mounting base 4 and is equipped with a handwheel 8. By manually turning the handwheel 8, the lead screw 7 is rotated. The thread on the outer wall of the lead screw 7 drives the slider 5 to slide and adjust its lateral position. A cutting machine 6 is installed at the bottom of the slider 5 to process the dressing packaging. Example

[0034] Reference Figure 6 and Figure 7 This embodiment is a further description based on Embodiment 1. When it is necessary to process multiple edges of a packaging bag for easy tearing, it is often necessary to first remove the packaging bag and adjust its position before positioning and processing, which will delay the processing progress. This embodiment improves upon this. The inner wall of the base 1 is rotatably connected to a worm gear 24 and a main shaft 25. One of the handwheels 8 is fixedly connected to the outer wall of the worm gear 24. The outer wall of the main shaft 25 is fixedly connected to a worm wheel 26. The teeth of the worm gear 24 and the worm wheel 26 are meshed. The main shaft 25 is fixedly connected to the outer wall of the processing table 20.

[0035] Specifically, when it is necessary to adjust the position of the packaging bag for multi-directional processing, simply turn the handwheel 8 at the bottom manually to drive the worm gear 24 to rotate. The worm gear 24 then drives the worm wheel 26 and the main shaft 25 to rotate through meshing. This allows the main shaft 25 to drive the processing table 20 at the top to rotate synchronously with the packaging bag placed on the upper surface for position adjustment. At the same time, the self-locking characteristics of the worm gear 24 and the worm wheel 26 are used to fix the angle, thereby improving processing efficiency.

[0036] Working principle: When using this positioning device to process the easy-tear opening of the individual packaging of sterile dressings, the sterile dressing packaging bag is placed above the processing table 20. The clamping block 23 is rotated out from the multiple slots of the processing table 20 and pulled, which drives the connecting rod 22 and the spring 21 to clamp the packaging bag on all four sides in sequence, ensuring its stability during the processing.

[0037] Then, depending on the required cutting position, manually rotate the top handwheel 8 to drive the lead screw 7 to rotate, which in turn drives the slider 5, which is threaded on the outer wall of the lead screw 7, to slide with the cutting machine 6 to change the position of the horizontal axis. Then, start the telescopic rod 3 to drive the entire mounting base 4, slider 5 and cutting machine 6 to adjust the position in the longitudinal direction. Then, use the cutting machine 6 to process the easy-tear opening of the packaging bag.

[0038] As the mounting base 4 slides longitudinally continuously driven by the telescopic rod 3, the rack 12 fixed on the mounting base 4 will mesh and drive the large gear 13 to rotate. The large gear 13 will then mesh and drive the small gear 15 and the rotating shaft 14 to rotate. Through the synchronous pulley 18 and the transmission belt, the rotating shaft 14 will transmit the rotational force to the drive rod 16. The end of the drive rod 16 will drive the fan 17 to operate, blowing the debris of the packaging bag cut by the cutting machine 6 on the processing table 20 in front, so that it falls into the collection trough 19 further in front for collection.

[0039] If the packaging bag needs to be cut in multiple directions, the handwheel 8 at the bottom can be rotated manually to drive the worm gear 24 to rotate. Through meshing, the worm wheel 26 and the main shaft 25 will rotate together, thereby driving the processing table 20 at the top and the packaging bag to rotate together, thus adjusting the processing position.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
