Abstract
Description
Technical Field
[0001] This utility model belongs to the field of nose strip processing technology, and in particular relates to a nose strip positioning and die-cutting device. Background Technology
[0002] In the medical field, nasal strips are commonly used for positioning and fixing gastric tubes. The usual method involves medical staff using scissors to cut the strips to the appropriate shape, a rather cumbersome process. Furthermore, traditional methods often employ a single-blade layout, making it difficult to precisely shape the strips to fit the complex "I" shape and other contours of the nasal cavity, resulting in poor adhesion and a tendency for the gastric tube to slip or cause localized pressure injury. In addition, the method of fixing rolled nasal strips relies on manual pressing or rigid clamping, which can easily lead to errors during cutting due to uneven material tension or misalignment, even damaging the adhesive layer and affecting the actual effectiveness. These factors limit the application of nasal strips in clinical settings for rapid and precise positioning of gastric tubes. Utility Model Content
[0003] The purpose of this invention is to provide a nasal strip positioning die-cutting device to solve the problems of insufficient cutting precision, unstable material fixation, and easy rewinding of the thread when manually cutting nasal strips with scissors in the prior art. This device achieves high-precision die-cutting of nasal strips for gastric tube positioning, efficient edge separation, and self-locking of material unwinding, thereby improving the fit of the nasal strip and the convenience of clinical operation.

[0005] Meanwhile, the inner cavity of the die-cutting plate is provided with a storage frame, wherein a roll nose sticker is provided on the left side of the inner cavity of the storage frame, and the roll nose sticker is set on the outer surface of the feed shaft. The rear end of the feed shaft is connected to the inner wall of the storage frame through a bearing. A self-locking structure is installed at the rear shaft end of the feed shaft surface.
[0006] Preferably, an upper cover is movably mounted on the upper part of the lower housing via a pivot.
[0007] Meanwhile, an auxiliary cutting plate is provided on the side of the upper cover near the die-cutting plate, and the auxiliary cutting plate, together with the die-cutting plate, can assist in the secondary die-cutting and shaping of the formed nose strip.
[0008] Preferably, a die-cutting table is placed in the inner cavity of the lower housing, and the die-cutting table is used in conjunction with the die-cutting structure on the die-cutting plate to perform die-cutting processing on the required nose strips;
[0009] The left side of the die-cutting table surface is provided with a guide groove for the surface of the rolled nose patch to pass through, and the upper and lower ends of the guide groove surface are rounded.
[0010] Meanwhile, a receiving / discharging slot is located on the left side of the storage frame.
[0011] Preferably, the die-cutting structure includes a slitting blade and a forming blade, the forming blade being U-shaped. There are multiple slitting blades, while there are two forming blades symmetrically arranged along the axis of the die-cutting plate.
[0012] Preferably, pressure plates are movably connected to the left and right sides of the end of the die-cutting table via a rotating shaft, and assembly grooves for use with the pressure plates are opened through the left and right ends of the die-cutting plate surface.
[0013] Preferably, the inner cavity of the storage frame is provided with a storage shaft, wherein the storage shaft is arranged in pairs and evenly in the inner cavity of the storage frame, and the rear side of the storage shaft is connected to the rear inner wall of the storage frame.
[0014] Preferably, the outer surface of the storage shaft is slidably fitted with a rolled nose patch, and the front side of the storage frame is movably mounted with a door via a pivot.
[0015] Preferably, a plurality of guide rods are provided on the left side of the inner cavity of the storage frame. The guide rods are used to assist in guiding and positioning the surface of the rolled nose patch during loading and unloading. A semi-arc guide plate is provided at the end of the left side of the storage frame.
[0016] Preferably, the self-locking structure includes a mounting plate, a ratchet, and a pawl, with the ratchet and pawl working together.
[0017] Preferably, the ratchet and pawl mesh with each other, with the ratchet sleeved on the surface of the wire feeding shaft, while the pawl is movably mounted on one side of the mounting plate.
[0018] The nose strip positioning and die-cutting device of this utility model has the following advantages:
[0019] This nose strip positioning and die-cutting device allows the user to open the upper shell cover by the handle during nose strip processing, revealing the die-cutting table and storage frame inside the lower shell cavity. A roll of nose strip is placed on the outer surface of the feed shaft, and its take-up and take-down ends are pulled sequentially through the take-up and take-down slot on the left side of the storage frame and the guide slot on the left side of the die-cutting table, laying it flat on the die-cutting table surface. At this time, one end of the pressure plate is moved to rotate around the shaft and stretch the coil spring, placing the roll of nose strip between the die-cutting table and the pressure plate, then released. The restoring force of the coil spring causes the pressure plate to press down and fix the material. The die-cutting plate is then flipped to fit against the die-cutting table. At this time, the forming blades symmetrically press down on the roll of nose strip to form an "I"-shaped nose strip. Adjacent cutting blades simultaneously cut and separate the finished product from the edge material, while the left cutting blade cuts strip-shaped nose strips.
[0020] During processing, the guide rod and semi-circular guide plate assist in guiding the nose strip's winding and unwinding path, avoiding wrinkles. The self-locking structure at the rear end of the unwinding shaft ensures unidirectional unwinding and prevents reverse winding. After die-cutting, the top cover is opened to remove the finished nose strip. The remaining material can be stored back in the storage box, and the box door is closed for sealed storage. If secondary die-cutting and shaping are required, the auxiliary cutting plate and the die-cutting plate work together when the top cover is closed to further improve processing accuracy. The entire process achieves integrated operation of material positioning, cutting separation, and waste management through mechanical linkage, improving nose strip processing efficiency and finished product consistency.

[0036] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a nose strip positioning and die-cutting device.
[0037] like Figures 1-8 As shown, the nose strip positioning and die-cutting device of this utility model includes a lower housing 100, and an upper housing cover 110 is movably mounted on the upper part of the lower housing 100 via a rotating shaft. The lower housing 100 and the upper housing cover 110 are movably mounted together by bearings. When the upper housing cover 110 and the lower housing 100 are attached, a sealed space can be formed for storing the parts required for nose strip positioning and die-cutting.
[0038] To facilitate the user in opening the upper cover 110, a handle is fastened to one side of the upper cover 110 by bolts. This increases the contact area between the user and the upper cover 110, making it easier for the user to open and close the lower cover 100.
[0039] The lower housing 100 has a die-cutting plate 300 mounted on its inner cavity end via a pivot. Meanwhile, the upper housing 110 has an auxiliary cutting plate 500 on the side near the die-cutting plate 300. The auxiliary cutting plate 500, in conjunction with the die-cutting plate 300, can assist in the secondary die-cutting and shaping of the formed nose strip.
[0040] One side of the die-cutting plate 300 is equipped with a die-cutting structure for die-cutting rolls of nose strips.
[0041] The die-cutting structure includes a slitting blade 310 and a forming blade 320. The forming blade 320 is U-shaped. There are multiple slitting blades 310, while there are two forming blades 320 and they are symmetrically arranged along the axis of the die-cutting plate 300.
[0042] Both the slitting blade 310 and the forming blade 320 are used in conjunction with the die-cutting table 200. When cutting the roll of nose strip 700 into the nose strip required by the user, the roll of nose strip 700 is pulled to move the unwinding end and lay it flat on the die-cutting table 200. Then, the die-cutting plate 300 is rotated to fit the opposite side of the die-cutting table 200, so that the forming blade 320 and the forming blade 320 press down on the roll of nose strip 700 on the die-cutting table 200 to die-cut the roll of nose strip 700 into the nose strip required.
[0043] The advantage of setting three slitting blades 310 and two forming blades 320 in this solution is that the two opposing forming blades 320 can cut the rolled nose strip 700 into the required "I" shaped nose strip, while the slitting blades 310 adjacent to the forming blades 320 are used to separate the cut and formed "I" shaped nose strip from the rolled nose strip 700; and the two slitting blades 310 on the left can cut and separate into strip nose strips.
[0044] Meanwhile, the inner cavity of the die-cutting plate 300 is provided with a storage frame 120. A rolled nose strip 700 is provided on the left side of the inner cavity of the storage frame 120. The rolled nose strip 700 is sleeved on the outer surface of the feed shaft 600 and is then movably placed in the inner cavity of the storage frame 120 by the feed shaft 600. The rear end of the feed shaft 600 is connected to the inner wall of the storage frame 120 through a bearing. The rolled nose strip 700 is sleeved on the outer surface of the feed shaft 600, and one end of the rolled nose strip 700 is pulled outward until the end of the rolled nose strip 700 is above the die-cutting table 200. Then, the required nose strip is die-cut and formed in conjunction with the die-cutting structure on the die-cutting plate 300.
[0045] The inner cavity of the lower housing 100 houses a die-cutting table 200, which is used in conjunction with the die-cutting structure on the die-cutting plate 300 to perform die-cutting on the required nose strips.
[0046] like Figure 6 As shown, in order to fix the rolled nose strip 700 into the required nose strip during processing, pressure plates 400 are movably connected to the left and right sides of the end of the die-cutting table 200 via rotating shafts. A coil spring is provided at the rotating shaft on the pressure plate 400. The coil spring can provide a downward pressing and restoring force to the pressure plate 400. When one end of the pressure plate 400 is moved, it rotates around the rotating shaft. At this time, the coil spring is stretched. After the pressure plate 400 is released, the pressure plate 400 is driven to move down and reset by the self-actual force of the coil spring, thereby fixing the surface of the rolled nose strip 700 on the die-cutting table 200. This prevents the surface of the rolled nose strip 700 from moving freely without restraint during cutting, thereby avoiding affecting the nose strip die-cutting and forming.
[0047] To avoid motion interference between the pressure plate 400 and the die-cutting structure on the die-cutting plate 300 while the pressure plate is pressing down, such as... Figure 6As shown, both ends of the die-cutting plate 300 are provided with assembly grooves 330 for use with the pressure plate 400. The cavity size of the assembly groove 330 is larger than that of the pressure plate 400, and the opening position of the assembly groove 330 corresponds to the installation position of the pressure plate 400. When the pressure plate 400 presses down on the rolled nose sticker 700 on the die-cutting table 200 to position it, when the corresponding rolled nose sticker 700 is die-cut, the die-cutting plate 300 flips and fits against the surface of the die-cutting table 200, the pressure plate 400 is exactly in the inner cavity of the assembly groove 330, thereby avoiding motion interference between the pressure plate 400 and the assembly groove 330.
[0048] Among them, such as Figure 5 As shown, a guide groove 201 is provided through the left side of the die-cutting table 200 for the surface of the rolled nose strip 700 to pass through. The upper and lower ends of the guide groove 201 are rounded. On the one hand, this can prevent the surface of the rolled nose strip 700 from being scratched when it is pulled out and put in. On the other hand, it can also guide the roll-up and unrolling ends of the rolled nose strip 700.
[0049] At the same time, such as Figure 4 As shown, a receiving slot 121 is provided on the left side of the storage frame 120. The receiving slot 121 has the same function as the guide slot 201, both of which can allow the receiving end of the rolled nose patch 700 to pass through.
[0050] The storage frame 120 has a storage shaft 610 in its inner cavity. The storage shaft 610 is arranged in pairs and evenly in the inner cavity of the storage frame 120. The rear side of the storage shaft 610 is connected to the rear inner wall of the storage frame 120. Therefore, the storage shaft 610 can be used to assist in supporting and storing the rolled nose patch 710.
[0051] The outer surface of the storage shaft 610 is slidably fitted with a roll of nose strip 710, and the front of the storage frame 120 is movably installed with a door via a pivot. Therefore, the inner cavity of the storage frame 120 can be closed by the door, and when the door is opened, it is convenient to install the roll of nose strip 700 and store the roll of nose strip 710.
[0052] Multiple guide rods 620 are provided on the left side of the inner cavity of the storage frame 120. The guide rods 620 are used to assist in guiding and positioning the surface of the rolled nose patch 700 during loading and unloading. A semi-arc guide plate 630 is provided at the left end of the storage frame 120. The semi-arc guide plate 630, together with the guide rods 620, guides the loading and unloading end of the rolled nose patch 700 to prevent wrinkles from forming during transportation.
[0053] To prevent the pay-off shaft 600 from rotating arbitrarily, a self-locking structure is installed at the rear shaft end of the pay-off shaft 600. The self-locking structure ensures that the pay-off shaft 600 can only rotate in one direction, and when the pay-off shaft 600 rotates in the opposite direction, it is self-locked and fixed.
[0054] The self-locking structure includes a mounting plate 800, a ratchet 810, and a pawl 820, with the ratchet 810 and pawl 820 working together. The ratchet 810 and pawl 820 mesh with each other, and the ratchet 810 is sleeved on the surface of the wire feeding shaft 600. At the same time, the pawl 820 is movably mounted on one side of the mounting plate 800, wherein the side of the mounting plate 800 away from the pawl 820 is mounted to the inner wall of the storage frame 120 via a support rod.
[0055] In use, when the pay-off shaft 600 rotates to pull and release the coiled nose tape 700, the corresponding ratchet 810 rotates along with the pay-off shaft 600, and the pawl 820 cannot interfere with its movement. Similarly, when the pay-off shaft 600 drives the ratchet 810 to rotate in the opposite direction, the pawl 820 will press against the ratchet 810 to prevent the pay-off shaft 600 from moving in the opposite direction. This can help position the coiled nose tape 700 and prevent the pay-off shaft 600 from reversing and causing the coiled nose tape 700 pulled out to rewind back together.
[0056] Working principle of a nose strip positioning die-cutting device: When processing nose strips, the user opens the upper shell cover 110 through the handle, exposing the die-cutting table 200 and the storage frame 120 in the inner cavity of the lower shell 100. A roll of nose strip one 700 is sleeved on the outer surface of the unwinding shaft rod 600, and its winding and unwinding ends are successively pulled through the winding and unwinding slot 121 on the left side of the storage frame 120 and the guiding connection slot 201 on the left side of the die-cutting table 200, and laid flat on the surface of the die-cutting table 200. At this time, one end of the pressing plate 400 is toggled to rotate around the rotating shaft and stretch the torsion spring. After placing the roll of nose strip one 700 between the die-cutting table 200 and the pressing plate 400 and then releasing it, the pressing plate 400 is pressed down by the restoring force of the torsion spring to fix the material. Subsequently, the die-cutting plate 300 is flipped to fit the die-cutting table 200. At this time, the forming knives 320 symmetrically press down on the roll of nose strip one 700 to form a "worker" shaped nose strip, and the adjacent slitting knives 310 synchronously cut and separate the finished product and the edge material, while the left slitting knife 310 cuts the strip-shaped nose strip. During the processing, the guide rod 620 and the semi-circular guide plate 630 assist in guiding the winding and unwinding path of the roll of nose strip one 700 to avoid wrinkles, and the self-locking structure at the rear end of the unwinding shaft rod 600 ensures its one-way unwinding and prevents reverse winding. After die-cutting, the upper shell cover 110 is opened to take out the finished nose strip, and the remaining material can be re-stored in the storage frame 120, and the box door is closed for sealed storage. If secondary die-cutting and shaping are required, when the upper shell cover 110 is closed, the auxiliary cutting knife plate 500 and the die-cutting plate 300 cooperate to further improve the processing accuracy. The entire process realizes the integrated operation of material positioning, cutting and separation, and waste management through mechanical linkage, improving the processing efficiency and finished product consistency of the nose strip.

Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model.
