Description

Technical Field

[0001] This invention relates to the technical field of blood pressure cuffs, and more specifically, to equipment for manufacturing blood pressure cuffs. Background Technology

[0002] As a core component of non-invasive blood pressure monitoring devices, the quality of the manufacturing process of blood pressure cuffs directly affects whether they can meet the requirements of high-quality and high-efficiency manufacturing.

[0003] In existing manufacturing processes, equipment functional units are scattered, and there is a lack of effective integration between various processes; for example, from cutting the roll film to fixing the Velcro, to inserting the tubing and finally sealing it, the entire process is often completed by multiple independent machines.

[0004] This decentralized and independent layout leads to frequent material transfers, positioning adjustments, and manual intervention during the production process. This not only increases non-productive time consumption but also easily causes strip wrinkles, displacement, or contamination due to repeated operations, affecting the stability of subsequent processes.

[0005] Looking further, in existing technologies, the fastening of Velcro is mostly done using ordinary hot press machines or sewing equipment, which can easily lead to problems such as incomplete welding and burns to the fabric. In the process of connecting the tubing, drilling, insertion, and heat fusion are often done on different equipment, making it difficult to ensure the consistency of the insertion depth and heat fusion pattern of the tubing, thus causing quality problems in the blood pressure cuff during use. Summary of the Invention

[0006] The purpose of this invention is to provide a blood pressure cuff manufacturing device, which aims to solve the problem of poor blood pressure cuff manufacturing performance in the prior art.

[0007] The present invention is implemented as follows: a blood pressure cuff manufacturing equipment includes a feeding station, a welding station, a punching station, a cannula insertion station, a cutting station, a folding station, and a forming station; the feeding station has a rolled film, and the rolled film has multiple square-shaped and integral strips. The strip has a center line in the middle, and the strip has a front section and a back section. The front section and the back section are located on both sides of the center line. Hook and loop fasteners are placed on the front section and the back section respectively, and the two hook and loop fasteners are arranged diagonally. The welding station is equipped with a lower pressure plate that presses against the strip. The bottom of the lower pressure plate is equipped with a welding ring. The welding ring presses against the outer periphery of the hook and loop fastener to heat-press and weld the hook and loop fastener to the strip. The punching station is equipped with a longitudinally arranged punching cylinder, which is opened on the front section to form a through hole arranged vertically; the tube insertion station is equipped with a tube insertion clamp, which inserts the tube longitudinally into the through hole, and the tube has a lower section located below the through hole and an upper section located above the through hole. The insertion station has a heat-fusion head located below the strip. The heat-fusion head heat-fuses the lower section to form a heat-fusion sheet. The heat-fusion sheet is fixed to the bottom of the strip so that the tubing and the strip are connected as one piece. The cutting station has a cutting blade that cuts and separates the strip from the roll film, thereby separating the strip from the roll film; The folding station is provided with a jig plate that carries the front section of the strip. The bottom of the jig plate has a scraper that abuts the back section against the bottom of the jig plate. The front section and the back section are arranged in a folded manner on the jig plate to form a folded strip. The forming station is equipped with a forming welding head, which presses against the outer periphery of the folded piece to heat-press the outer periphery of the folded piece into a closed annular edge. The folded piece forms a blood pressure cuff, and the front section and the back section enclose a closed internal cavity. The tubing is connected to the internal cavity.

[0008] Furthermore, a movable plate is provided below the tape, and a vacuum suction head is provided on the movable plate. After the tape is placed on the movable plate, the vacuum suction head adsorbs the tape and fixes the tape on the movable plate.

[0009] Furthermore, the welding ring encloses and forms an intermediate area, and the intermediate area is provided with a bonding piece. When the welding ring presses against the hook and loop fastener and welds it, the bonding piece and the hook and loop fastener on the strip are hooked together. When the lower pressure plate moves upward, it drives the strip to move synchronously.

[0010] Furthermore, the intermediate region is provided with a detachable central plate, and the central plate is provided with a plurality of bonding pieces, which are exposed at the bottom of the central plate and are arranged in an array.

[0011] Furthermore, the middle plate has a hollowed-out groove with a bottom opening, and an inner block is provided in the hollowed-out groove. The bonding piece is connected to the inner block and is exposed at the bottom of the middle plate through the bottom opening of the hollowed-out groove. The bonding piece is rectangular in shape.

[0012] Furthermore, the lower pressure plate is provided with a guide plate and a connecting plate. The guide plate is provided with a guide shaft, which moves from top to bottom through the lower pressure plate and moves into the middle plate. The connecting plate is provided with a mounting groove, and the middle plate is provided with a connecting shaft, which moves from bottom to top through the lower pressure plate and the connecting plate. The connecting shaft has a magnetic suction section that passes through the mounting groove. There is an annular gap between the magnetic suction section and the inner sidewall of the mounting groove. A magnetic suction ring is provided in the annular gap. The magnetic suction ring is sleeved on the outer periphery of the magnetic suction section and is magnetically connected to the magnetic suction section and the connecting plate respectively, so that the middle plate is fixedly connected to the lower pressure plate.

[0013] Furthermore, the insertion station is equipped with a movable frame, which has two spaced-apart feeding chambers for placing the tubing; the insertion station is equipped with a positioning head, which presses against the strip, and the positioning head has a longitudinally arranged positioning hole for the tubing to pass through longitudinally. When the tubing passes through the through hole, the insertion clamp and the positioning head clamp and fix the tubing longitudinally. The hot melt head is provided with a hot melt groove. After the hose passes through the through hole to form the lower section, the lower section abuts against the bottom of the hot melt groove. The hot melt head presses upward until the lower section is hot melted into the hot melt sheet, which fills the hot melt groove.

[0014] Furthermore, the side of the feeding chamber is provided with a material transfer fixture and a material transfer clamp. The material transfer fixture is provided with a material transfer groove with a top opening and horizontal arrangement. The material transfer clamp clamps the rubber tube in the feeding chamber and places the rubber tube horizontally in the material transfer groove. The material transfer fixture is disconnected and forms a cutout position for inserting the tube clamp to hold the rubber tube.

[0015] Furthermore, the bottom of the hot melt tank is conical, forming a conical surface. The middle part of the conical surface protrudes upward, forming a central protrusion. Along the central protrusion to the outer periphery of the conical surface, the conical surface is arranged inclined downward. The conical surface is provided with multiple flow guide grooves, which are arranged at intervals around the central protrusion. The upper ends of the flow guide grooves converge at the central protrusion, and the lower ends of the flow guide grooves extend to the outer periphery of the conical surface. The conical surface has a flow guide surface located between adjacent flow guide grooves, and the flow guide surface is provided with multiple pointed protrusions, which are arranged at intervals and staggered along the length direction of the flow guide surface. During the process of the hot melt head pressing the lower section upwards, the middle protrusion is embedded inside the lower section, and the end of the lower section abuts against the conical surface; during the process of the lower section being hot melted into a hot melt sheet, the adhesive formed by the hot melt of the lower section flows along the guide groove of the conical surface, and multiple pointed protrusions are embedded in the hot melt sheet, forming multiple upper pressure grooves on the hot melt sheet.

[0016] Furthermore, the side of the fixture plate has a side edge, and two folding clamps are provided on the outer side of the side edge. The folding clamps have two folding arms that clamp or separate from each other, and the two folding arms are arranged vertically. The fixture plate has two hollowed-out grooves arranged in a perforated manner. The two hollowed-out grooves are arranged sequentially and spaced apart along the length of the side edge. The hollowed-out grooves penetrate the side edge. The scraper is arranged parallel to the side edge. An air blowing head is provided on the outer side of the side edge. The air blowing head is arranged at an angle and blows air towards the lower part of the fixture plate. When the front section of the strip is laid on the fixture plate, the center line and the side edge are aligned vertically, and the back section is freely arranged; the air blowing head blows air towards the back section so that the back section swings towards the bottom of the fixture plate, and the scraper abuts against the back section and scrapes inward away from the side edge so that the back section abuts against the bottom of the fixture plate. When the back section abuts against the bottom of the fixture plate, the front section and the back section are arranged in a folded shape to form the folded piece; the two folding clamp arms of the folding clamp head are located above and below the fixture plate, respectively, and are arranged vertically aligned with the empty groove strip. The two folding clamp arms clamp the folded piece and detach the folded piece from the fixture plate.

[0017] Compared with the prior art, the blood pressure cuff manufacturing equipment provided by the present invention first integrates the scattered processes of multiple independent machines into a complete production line through the systematic integration of the feeding station, welding station, drilling station, tube insertion station, cutting station, folding station and forming station.

[0018] This continuous automated manufacturing process not only reduces the time lost due to manual intervention and material transfer, but also ensures the precision of the connection between each process, thus improving production efficiency while guaranteeing the manufacturing effect of blood pressure cuffs.

[0019] Secondly, on the one hand, the welding station of the equipment uses the cooperation of the lower pressure plate and the welding ring to achieve precise hot-press welding of the Velcro patch, effectively avoiding quality problems such as false welding and burning of the fabric. On the other hand, the insertion station combined with the heat fusion head ensures that the insertion depth and heat fusion shape of the tubing are consistent, thereby improving the connection strength between the tubing and the pad and reducing the risk of air leakage during the use of the blood pressure cuff.

[0020] Finally, the coordinated work of the folding station and the forming station enables accurate edge sealing of the folded sheet and efficient forming of the airbag. Furthermore, through the cooperation of the jig plate and the scraper, the sheet remains flat during the folding process. The subsequent hot-press sealing operation of the forming and welding head ensures uniform sealing of the airbag edge, thereby improving the airtightness and dimensional accuracy of the airbag.

[0025] Reference Figures 1-13 The image shows a preferred embodiment of the present invention.

[0026] The blood pressure cuff manufacturing equipment includes a feeding station, a welding station, a punching station, a cannula insertion station, a cutting station, a folding station, and a forming station; the feeding station has a roll of film, and the roll of film has multiple square-shaped and integral strips 100. The strip 100 has a center line 101 in the middle, and the strip 100 has a front section 102 and a back section 103. The front section 102 and the back section 103 are located on both sides of the center line 101. A hook and loop fastener 104 is placed on the front section 102 and the back section 103 respectively, and the two hook and loop fasteners 104 are arranged diagonally. The welding station is provided with a lower pressure plate 300 that presses against the strip 100. The bottom of the lower pressure plate 300 is provided with a welding ring 301. The welding ring 301 presses against the outer periphery of the hook and loop fastener 104 to heat-press the hook and loop fastener 104 to the strip 100. The punching station is equipped with a longitudinally arranged punching cylinder, which is opened on the front section to form a through hole 105 arranged vertically; the tube insertion station is equipped with a tube insertion clamp 407, which inserts the tubing 200 longitudinally into the through hole. The tubing 200 has a lower section 201 located below the through hole 105 and an upper section 202 located above the through hole 105. The insertion station has a heat fusion head 500 located below the strip 100. The heat fusion head 500 heat-melts the lower section 201 to form a heat fusion sheet 203. The heat fusion sheet 203 is fixed to the bottom of the strip 100 so that the tubing 200 and the strip 100 are connected as one unit. The cutting station has a cutting blade that cuts and separates the strip from the roll film, so that the strip 100 is separated from the roll film; The folding station is equipped with a fixture plate 600 that carries the front section 102 of the strip 100. The bottom of the fixture plate 600 has a scraper 605 that abuts the back section 103 against the bottom of the fixture plate 600. The front section 102 and the back section 103 are arranged in a folded manner on the fixture plate 600 to form a folded strip. The forming station is equipped with a forming welding head, which presses against the outer periphery of the folded piece to heat-press the outer periphery of the folded piece to form a closed ring edge. The folded piece forms a blood pressure cuff, and the front section 12 and the back section 103 enclose and form a closed internal cavity. The tubing is connected to the internal cavity.

[0027] The blood pressure cuff manufacturing equipment provided above first integrates the scattered processes of multiple independent machines into a complete production line through the systematic integration of the feeding station, welding station, drilling station, tube insertion station, cutting station, folding station and forming station.

[0028] This continuous automated manufacturing process not only reduces the time lost due to manual intervention and material transfer, but also ensures the precision of the connection between each process, thus improving production efficiency while guaranteeing the manufacturing effect of blood pressure cuffs.

[0029] Secondly, on the one hand, the welding station of the equipment uses the cooperation of the lower pressure plate 300 and the welding ring 301 to achieve precise hot-press welding of the Velcro patch 104, effectively avoiding quality problems such as false welding and burning of the fabric. On the other hand, the insertion station combined with the heat fusion head 500 ensures that the insertion depth and heat fusion shape of the tubing 200 are consistent, thereby improving the connection strength between the tubing 200 and the strip 100 and reducing the risk of air leakage during the use of the blood pressure cuff.

[0030] Finally, the coordinated work of the folding station and the forming station enables accurate edge sealing of the folded piece and efficient forming of the airbag. Furthermore, through the cooperation of the jig plate 600 and the scraper 605, the strip 100 remains flat during the folding process. The subsequent hot-press sealing operation of the forming welding head ensures uniform sealing of the airbag edge, thereby improving the airtightness and dimensional accuracy of the airbag.

[0031] In this embodiment, a movable plate is provided below the tape 100, and a vacuum suction head is provided on the movable plate. After the tape 100 is placed on the movable plate, the vacuum suction head adsorbs the tape 100 and fixes the tape 100 on the movable plate.

[0032] After the continuous roll of film is cut into strips 100, the strips 100 need to be conveyed to the next station. At this time, the vacuum suction head picks up the strips 100 and fixes them stably on the moving plate. Even if the strips 100 are affected by vibration or airflow during the transfer of the moving plate, they can remain flat and will not shift.

[0033] This provides a good foundation for subsequent welding, drilling and other processes, ensuring the manufacturing effect of the blood pressure cuff. For example, if the strip 100 is displaced when welding the hook and loop fastener 104, the welding position of the hook and loop fastener 104 will be inaccurate, affecting the normal use of the blood pressure cuff. In addition, this stable fixing method can adapt to strips 100 of different materials and thicknesses, and has wide applicability.

[0034] In this embodiment, the welding ring 301 encloses and forms a middle area, and the middle area is provided with a bonding piece 302. When the welding ring 301 presses against the hook and loop fastener 104 for hot pressing and welding, the bonding piece 302 and the hook and loop fastener 104 on the strip 100 are hooked together. When the pressure plate 300 moves upward, it drives the strip 100 to move synchronously.

[0035] During the manufacturing process, the welding ring 301 first presses against the outer periphery of the hook and loop fastener 104 to heat-press the hook and loop fastener 104 and the strip 100. At this time, the bonding piece 302 in the middle area is further bonded to the hook and loop fastener 104, which enhances the connection strength between the hook and loop fastener 104 and the strip 100.

[0036] When the pressure plate 300 moves upward, the tape 100 can move synchronously due to the tight fit between the bonding piece 302 and the hook and loop fastener 104, ensuring the continuity of the manufacturing process.

[0037] This not only improves manufacturing efficiency but also ensures a strong connection between the Velcro 104 and the strip 100, preventing incomplete welding or burns to the fabric, thereby improving the manufacturing effect of the blood pressure cuff.

[0038] In this embodiment, a detachable central plate 303 is provided in the middle area, and a plurality of bonding pieces 302 are provided on the central plate 303. The plurality of bonding pieces 302 are exposed at the bottom of the central plate 303 and are arranged in an array.

[0039] In this way, when it is necessary to replace the Velcro patch 104 with different specifications or materials, it is only necessary to disassemble the middle plate 303 and replace the corresponding middle plate 303 and bonding patch 302 to adapt to new manufacturing requirements, thereby increasing the flexibility and versatility of the equipment.

[0040] Furthermore, the multiple adhesive pads 302 are arranged in an array, which can evenly adhere to the hook and loop fastener 104, ensuring consistent connection strength between the hook and loop fastener 104 and the strip 100, thus guaranteeing the quality stability of the blood pressure cuff.

[0041] In this embodiment, the middle plate 303 is provided with a hollow groove 304 with a bottom opening, and an inner block 305 is provided in the hollow groove 304. The bonding piece 302 is connected to the inner block 305 and is exposed at the bottom of the middle plate 303 through the bottom opening of the hollow groove 304. The bonding piece 302 is rectangular in shape.

[0042] In this way, the rectangular adhesive piece 302 matches the shape of the Velcro piece 104, allowing for a tight fit and ensuring the connection strength between the Velcro piece 104 and the strip 100. When the adhesive piece 302 needs to be replaced, simply remove the inner block 305 from the bottom opening of the slot 304, replace it with a new adhesive piece 302, and reinstall it. This simplifies the equipment maintenance process, improves production efficiency, and ensures the manufacturing effect of the blood pressure cuff.

[0043] In this embodiment, the lower pressure plate 300 is provided with a guide plate 306 and a connecting plate 308. The guide plate 306 is provided with a guide shaft 307, which moves from top to bottom through the lower pressure plate 300 and moves into the middle plate 303. The connecting plate 308 is provided with a mounting groove, and the middle plate 303 is provided with a connecting shaft 309, which moves from bottom to top through the lower pressure plate 300 and the connecting plate 308. The connecting shaft 309 has a magnetic section 310 that passes through the mounting groove. There is an annular gap between the magnetic section 310 and the inner sidewall of the mounting groove. A magnetic ring 311 is provided in the annular gap. The magnetic ring 311 is sleeved on the outer periphery of the magnetic section 310 and is magnetically connected to the magnetic section 310 and the connecting plate 308 respectively, so that the middle plate 303 is fixedly connected to the lower pressure plate 300.

[0044] On the one hand, the cooperation between the guide shaft 307 and the guide plate 306 ensures that the lower pressure plate 300 remains stable during movement, avoiding shaking or deviation, thereby ensuring that the welding ring 301 can accurately press against the Velcro piece 104, and that there is a stable connection and precise alignment between the middle plate 303 and the lower pressure plate 300.

[0045] On the other hand, the magnetic connection provides a quick and reliable fixing method, which allows the middle plate 303 to be firmly connected to the lower pressure plate 300, while facilitating disassembly and replacement; it not only improves operating efficiency and reliability, but also facilitates maintenance and adjustment during the manufacturing process, reduces downtime, and improves overall production efficiency.

[0046] In this embodiment, the insertion station is provided with a movable frame 400, and the movable frame 400 is provided with two spaced-apart feeding chambers 401 for placing the tubing 200; the insertion station is provided with a positioning head 402, which presses against the strip 100. The positioning head 402 is provided with a positioning hole arranged longitudinally for the tubing 200 to pass through longitudinally. When the tubing 200 passes through the through hole 105, the insertion clamp 407 and the positioning head 402 clamp and fix the tubing 200 longitudinally. The hot melt head 500 is provided with a hot melt groove 501. After the tube 200 passes through the through hole 105 to form the lower section 201, the lower section 201 abuts against the bottom of the hot melt groove 501. The hot melt head 500 presses upward until the lower section 201 is melted into a hot melt sheet 203, which fills the hot melt groove 501.

[0047] During the feeding process, when one of the feeding chambers 401 has finished feeding the hose 200, the moving frame 400 moves the other fully loaded feeding chamber 401 to the feeding station to continue supplying the hose 200. The empty feeding chamber 401 can then be reloaded with the hose 200. This process of moving, loading, and feeding is repeated to meet the hose 200 supply required for the subsequent hose 200 and tape 100 connection process.

[0048] Then, through the cooperation of the insertion clamp 407 and the positioning head 402, the insertion depth and angle of the tubing 200 are ensured to be consistent. The lower section 201 is then heat-fused to connect it with the strip 100 as one unit, thereby improving the connection strength between the tubing 200 and the strip 100 and demonstrating a high-quality blood pressure cuff manufacturing effect.

[0049] In this embodiment, the side of the feeding chamber 401 is provided with a material transfer fixture 403 and a material transfer chuck 406. The material transfer fixture 403 is provided with a material transfer groove 404 with a top opening and horizontal arrangement. The material transfer chuck 406 clamps the rubber tube 200 in the feeding chamber 401 and places the rubber tube 200 horizontally in the material transfer groove 404. The material transfer fixture 403 is arranged in a discontinuous manner, forming a cut-out position 405 with a hollow arrangement for the insertion chuck 407 to insert and clamp the rubber tube 200.

[0050] This facilitates the transfer and insertion of the hose 200, improves production efficiency, and ensures the accuracy of hose 200 insertion. For example, during the manufacturing process, the transfer chuck 406 picks up the hose 200 from the loading chamber 401 and places it horizontally in the transfer groove 404. The setting of the disconnect position 405 facilitates the insertion chuck 407 to be inserted into the transfer groove 404, holding the hose 200 and inserting it into the through hole 105 of the strip 100.

[0051] In this embodiment, the bottom of the hot melt tank 501 is conical, forming a conical surface 502. The middle part of the conical surface 502 protrudes upward, forming a central protrusion 503. Along the central protrusion 503 to the outer periphery of the conical surface 502, the conical surface 502 is arranged inclined downward. The conical surface 502 is provided with a plurality of flow guide grooves 504, which are arranged at intervals around the central protrusion 503. The upper ends of the flow guide grooves 504 converge at the central protrusion 503, and the lower ends of the flow guide grooves 504 extend to the outer periphery of the conical surface 502. The conical surface 502 has a flow guide surface 505 located between adjacent flow guide grooves 504. The flow guide surface 505 is provided with a plurality of pointed protrusions 506, which are arranged at intervals and staggered along the length direction of the flow guide surface 505. During the process of the hot melt head 500 pressing the lower section 201 upwards, the central protrusion 503 is embedded in the interior of the lower section 201, and the end of the lower section 201 abuts against the conical surface 502; during the process of the lower section 201 being hot melted into a hot melt sheet 203, the adhesive formed by the hot melt of the lower section 201 is guided to flow along the guide groove 504 of the conical surface 502, and multiple pointed protrusions 506 are embedded in the hot melt sheet 203, forming multiple upper pressure grooves 507 on the hot melt sheet 203.

[0052] The structure of the conical surface 502 and the central protrusion 503 can guide the hot melt adhesive to flow evenly to the outer periphery. Then, the hot melt groove 501 optimizes the flow and distribution of the hot melt adhesive during the hot melting process, ensuring that the hot melt sheet 203 has a regular shape and uniform thickness.

[0053] In addition, the design of the flow channel 504 and the tip protrusion 506 further refines the flow path of the adhesive, and the multiple pressure grooves 507 formed on the hot melt sheet 203 give the hot melt sheet 203 better structural strength and sealing performance after curing.

[0054] In this embodiment, the side of the jig plate 600 has a side edge 601, and two folding clamps 602 are provided on the outer side of the side edge 601. The folding clamps 602 have two folding clamp arms 603 that clamp each other or separate from each other, and the two folding clamp arms 603 are arranged vertically. The jig plate 600 has two hollowed-out grooves 604 arranged in a hollowed-out manner. The two hollowed-out grooves 604 are arranged sequentially and spaced apart along the length direction of the side edge 601. The hollowed-out grooves 604 penetrate the side edge 601. The scraper 605 is arranged parallel to the side edge 601. An air blowing head 606 is provided on the outer side of the side edge 601. The air blowing head 606 is arranged at an angle and blows air towards the lower part of the jig plate 600. When the front section 102 of the strip 100 is laid on the jig plate 600, the center line 101 and the side edge 601 are aligned vertically, and the back section 103 is freely arranged; the air blowing head 606 blows air toward the back section 103 so that the back section 103 swings toward the bottom of the jig plate 600, and the scraper 605 abuts against the back section 103 and scrapes inward away from the side edge 601 so that the back section 103 abuts against the bottom of the jig plate 600. When the back section 103 abuts against the bottom of the jig plate 600, the front section 102 and the back section 103 are arranged in a folded shape to form a folded piece; the two folding clamping arms 603 of the folding clamp 602 are located above and below the jig plate 600 respectively, and are arranged vertically aligned with the empty groove strip 604. The two folding clamping arms 603 clamp the folded piece and detach the folded piece from the jig plate 600.

[0055] The folding station enables precise folding and rapid fixing of the strip 100; the cooperation of the air blowing head 606 and the scraper 605 allows the back section 103 to be flatly attached to the bottom of the jig plate 600, providing a good foundation for subsequent folding operations.

[0056] The folding clamp 602's up-and-down clamping method allows for quick and accurate removal of the folded piece from the fixture plate 600, ready for the next process.

[0057] This automated folding method not only improves production efficiency but also ensures the accuracy and effectiveness of the folding, allowing the blood pressure cuff to maintain a stable shape and good fit during use, thereby improving measurement accuracy and user comfort.
