Description

Technical Field

[0001] This utility model relates to the field of ostomy bag production technology, and in particular to an ostomy bag raw material cutting device with a positioning mechanism. Background Technology

[0002] Stomas are generally used for conditions such as rectal cancer, bladder cancer, and intestinal obstruction. To save the patient's life, doctors surgically remove the affected area. Patients with stomas experience changes in their bodies, and their excretions cannot be controlled at will. They need to use ostomy bags to store excretions such as urine and feces. Medical ostomy bags are classified into urinary ostomy bags and anorectal ostomy bags according to the patient's stoma rerouting situation. Each type of ostomy bag is broadly divided into two categories based on its design structure: adhesive and non-adhesive.

[0003] During the production of ostomy bags, slits need to be cut into the film first, and then adhesive tape needs to be assembled at the slits. During the film cutting process, the contact and separation of the cutter with the film causes the film to vibrate, resulting in wrinkles. Utility Model Content

[0004] This utility model discloses a cutting device for ostomy bag raw materials with a positioning mechanism, which aims to solve the technical problem that during the film cutting process, the film vibrates as the cutter contacts and separates from the film, thus causing wrinkles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A raw material cutting device for ostomy bags with a positioning mechanism includes a conveying track, an outer ring positioning mechanism disposed at the top of the conveying track, an inner ring positioning mechanism disposed at the bottom of the conveying track, and a smoothing mechanism connected to the outer ring positioning mechanism.

[0007] The outer ring positioning mechanism includes a hydraulic rod, a support rod 1 fixedly connected to the output end of the hydraulic rod, an annular cutter installed at the bottom end of the support rod 1, a circular support plate fixedly connected between the support rod 1 and the annular cutter, a snap-fit ​​cover movably sleeved on the outside of the support rod 1, a spring 1 connected between the inner wall of the snap-fit ​​cover and the circular support plate, and a square pressure plate fixedly connected to the bottom end of the snap-fit ​​cover.

[0008] The inner ring positioning mechanism includes a base plate, multiple perforations II disposed on the inner wall of the base plate, multiple air pipes II connected to the bottom ends of the multiple perforations II, and an air pump connected to the output end of the multiple air pipes II.

[0009] Two limiting support plates are symmetrically connected to the outer periphery of the first support rod, and two limiting inserts are fixedly connected to the top of the snap-fit ​​cover, with the two limiting inserts correspondingly and movably inserted into the limiting support plates.

[0010] By incorporating an outer ring positioning mechanism and an inner ring positioning mechanism, the outer ring positioning mechanism first uses a snap-fit ​​cover to press down and position the outer ring of the film before the annular cutter contacts the film. In the inner ring positioning mechanism, negative pressure is used to attract the film near the cutting position, thereby achieving area positioning and further preventing film displacement and wrinkles during the cutting process. At the same time, after the cutting is completed, the continuous attraction of the inner ring positioning mechanism can also greatly reduce the vibration amplitude of the surrounding film when the annular cutter detaches, further preventing wrinkles at the cut position.

[0011] In a preferred embodiment, the inner ring positioning mechanism further includes a filter frame, a filter screen disposed on the filter frame, a side frame, and a second support rod;

[0012] The top inner wall of the base plate is provided with an annular groove, and the annular groove covers the top of multiple perforations. The filter frame is embedded in the annular groove.

[0013] The side frame is fixedly connected to one side of the filter frame, and a limit hole is provided in the side frame. A square groove is connected to one side of the annular groove, and the side frame is embedded in the square groove.

[0014] A groove is provided on one side of the base plate, and a support rod passes through both the groove and the limiting hole. A handle is fixedly connected to one end of the support rod, and a spring is connected between the handle and the inner wall of the groove.

[0015] The bottom outer wall of the base plate is fixedly connected to a base frame, and the vacuum pump is installed on the base frame. The top of the base plate is provided with a groove, and the groove is located in an annular groove.

[0016] The inner ring positioning mechanism, through the setting of the filter screen, can disperse the suction force and provide support for the membrane at the suction position, preventing the membrane from being tightly adhered to the multiple perforations and causing indentations. In addition, the side frame is inserted into the square groove and the two are connected by inserting the support rod, which facilitates the installation and disassembly of the filter screen frame and prevents the filter screen frame from shifting during use.

[0017] In a preferred embodiment, the smoothing mechanism includes multiple baffles disposed at the bottom end of the square pressure plate, two multi-vent pipes, and a hot air blower connected to both multi-vent pipes simultaneously.

[0018] The baffles are divided into multiple groups, and each group is provided with two baffles. The square pressure plate is symmetrically provided with multiple through holes.

[0019] Each set of baffles is symmetrically arranged at the bottom of multiple perforations, and the baffles are connected to the bottom of the square pressure plate by spring hinges. Multiple output ends of each of the multiple air tubes extend into multiple perforations.

[0020] By incorporating a smoothing mechanism, hot air is blown out by a hot air blower and discharged from the output end of the multi-vent pipes on both sides, acting evenly on the surface of the film during the movement, which can smooth out wrinkles. Furthermore, by setting up baffles, the perforations can be blocked during the cutting process, thus preventing the hot air from being unevenly applied and causing the film to overheat and be damaged when stationary.

[0021] As described above, an ostomy bag material cutting device with a positioning mechanism includes a conveying track, an outer ring positioning mechanism disposed at the top of the conveying track, an inner ring positioning mechanism disposed at the bottom of the conveying track, and a smoothing mechanism connected to the outer ring positioning mechanism. The outer ring positioning mechanism includes a hydraulic rod, a support rod I fixedly connected to the output end of the hydraulic rod, an annular cutter installed at the bottom end of the support rod I, a circular support plate fixedly connected between the support rod I and the annular cutter, a snap-fit ​​cover movably sleeved outside the support rod I, a spring I connected between the inner wall of the snap-fit ​​cover and the circular support plate, and a square pressure plate fixedly connected to the bottom end of the snap-fit ​​cover. The inner ring positioning mechanism includes a base plate, multiple perforations II disposed on the inner wall of the base plate, multiple air pipes II connected to the bottom ends of the multiple perforations II, and a vacuum pump connected to the output end of the multiple air pipes II. The ostomy bag material cutting device with a positioning mechanism provided by this utility model has the technical effect of avoiding film displacement and wrinkles during the cutting process by using area positioning.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] The ostomy bag material cutting device with a positioning mechanism disclosed in this utility model is mainly used in the production of ostomy bags.

[0032] Reference Figures 1-3 A raw material cutting device for ostomy bags with a positioning mechanism includes a conveying track 3, an outer ring positioning mechanism 1 set at the top of the conveying track 3, an inner ring positioning mechanism 4 set at the bottom of the conveying track 3, and a smoothing mechanism 2 connected to the outer ring positioning mechanism 1.

[0033] The outer ring positioning mechanism 1 includes a hydraulic rod 101, a support rod 102 fixedly connected to the output end of the hydraulic rod 101, an annular cutter 105 installed at the bottom end of the support rod 102, a circular support plate 104 fixedly connected between the support rod 102 and the annular cutter 105, a snap-fit ​​cover 108 movably sleeved on the outside of the support rod 102, a spring 106 connected between the inner wall of the snap-fit ​​cover 108 and the circular support plate 104, and a square pressure plate 109 fixedly connected to the bottom end of the snap-fit ​​cover 108.

[0034] The inner ring positioning mechanism 4 includes a base plate 405, multiple perforations 413 disposed on the inner wall of the base plate 405, a multi-ventilation pipe 408 connected to the bottom of the multiple perforations 413, and a vacuum pump 409 connected to the output end of the multi-ventilation pipe 408. The outer ring positioning mechanism 1, through the setting of spring 106, first achieves the squeezing and positioning of the outer ring of the film by pressing down the snap cover 108, the pressure of spring 106, and the support of the base plate 405 before the annular cutter 105 contacts the film. In the inner ring positioning mechanism 4, through the multiple perforations 413 disposed in the inner ring and the vacuum pump 409 connected thereto, the film at the cutting position can be adsorbed by negative pressure, thereby achieving area positioning and further avoiding film displacement and wrinkle generation during the cutting process. At the same time, after the cutting is completed, the continuous adsorption of the inner ring positioning mechanism 4 can also greatly reduce the vibration amplitude of the surrounding film when the annular cutter 105 is removed, further avoiding wrinkle generation at the cut position.

[0035] Reference Figure 3 In a preferred embodiment, two limiting support plates 103 are symmetrically connected to the outer periphery of the support rod 102, and two limiting insert rods 107 are fixedly connected to the top of the snap-fit ​​cover 108, and the two limiting insert rods 107 are correspondingly and movably inserted into the limiting support plates 103.

[0036] Reference Figure 2 In a preferred embodiment, the inner ring positioning mechanism 4 further includes a filter frame 402, a filter 401 disposed on the filter frame 402, a side frame 403, and a support rod 411.

[0037] Reference Figure 2 In a preferred embodiment, the inner wall of the top end of the base plate 405 is provided with an annular groove 414, and the annular groove 414 covers the top end of multiple perforations 413, and the filter frame 402 is embedded in the annular groove 414.

[0038] Reference Figure 2 In a preferred embodiment, the side frame 403 is fixedly connected to one side of the filter frame 402, and the side frame 403 is provided with a limiting hole 404. A square groove 416 is connected to one side of the annular groove 414, and the side frame 403 is embedded in the square groove 416.

[0039] Reference Figure 2 In a preferred embodiment, a groove 412 is provided on one side of the base plate 405, and a support rod 411 passes through both the groove 412 and the limiting insertion hole 404. One end of the support rod 411 is fixedly connected to a handle 407, and a spring 410 is connected between the handle 407 and the inner wall of the groove 412.

[0040] Reference Figure 2In a preferred embodiment, a bottom frame 406 is fixedly connected to the bottom outer wall of the bottom plate 405, and the vacuum pump 409 is installed on the bottom frame 406. A groove 415 is provided at the top of the bottom plate 405, and the groove 415 is located in the annular groove 414. In the inner ring positioning mechanism 4, the suction force can be dispersed by the setting of the filter screen 401, and the film at the suction position can be supported to avoid the film being tightly adsorbed on the multiple perforations 413 and causing indentations. In addition, the side frame 403 is inserted into the square groove 416, and the connection between the two is established by inserting the support rod 411, which facilitates the installation and disassembly of the filter screen frame 402, and at the same time avoids the filter screen frame 402 from shifting during use.

[0041] Reference Figure 3 and Figure 4 In a preferred embodiment, the smoothing mechanism 2 includes multiple baffles 205 disposed at the bottom end of the square pressure plate 109, two multi-vent pipes 202, and a hot air blower 203 connected to the two multi-vent pipes 202.

[0042] Reference Figure 3 and Figure 4 In a preferred embodiment, the multiple baffles 205 are divided into multiple groups, and each group is provided with two baffles 205. The square pressure plate 109 is symmetrically provided with multiple through holes 201.

[0043] Reference Figure 3 and Figure 4 In a preferred embodiment, each set of baffles 205 is symmetrically arranged at the bottom end of multiple perforations 201, and the baffles 205 are connected to the bottom end of the square pressure plate 109 via spring-loaded hinges 204. Multiple output ends of each multi-vent pipe 202 extend into multiple perforations 201. Hot air is blown out of the smoothing mechanism 2 by a hot air blower 203 and discharged from the output ends of the multi-vent pipes 202 on both sides, acting evenly on the film surface during movement, thus smoothing wrinkles. During the downward cutting process, since the film is stationary at this time, and the multi-vent pipe 202 extending from the bottom of the perforation 201 can be retracted into the perforation 201 during the downward pressing of the square pressure plate 109, the bottom baffle 205 can block the perforation 201 under the action of the spring hinge 204, thus blocking the hot air and avoiding uneven hot air action in the stationary state, which would cause the film to overheat and be damaged. Conversely, when the square pressure plate 109 is lifted, the multi-vent pipe 202 extends out, which allows the hot air to be continuously blown out.

[0044] Working principle: The outer ring positioning mechanism 1, through the setting of spring 106, first achieves the squeezing and positioning of the outer ring of the film by pressing down the snap cover 108, the pressure of spring 106, and the support of the base plate 405 before the annular cutter 105 contacts the film. In the inner ring positioning mechanism 4, through the multiple perforations 413 set in the inner ring and the vacuum pump 409 connected to them, the film is adsorbed by negative pressure approaching the cutting position, thereby achieving area positioning and further avoiding film displacement and wrinkle generation during the cutting process. At the same time, after the cutting is completed, the continuous adsorption of the inner ring positioning mechanism 4 can also greatly reduce the vibration amplitude of the surrounding film when the annular cutter 105 is removed, further avoiding wrinkles at the cut position.

[0045] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
