Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical tool production, and more specifically, to a medical catheter packaging device. Background Art
[0002] The production of medical tools refers to the production of various treatment-assisting devices used in the medical process, and among them, medical catheters are tools that are used more frequently.
[0003] When producing catheters, multiple independent devices are usually used to complete various steps from production to packaging. At the same time, in the packaging step of existing automated devices, when packaging, the catheter needs to be wound to facilitate packaging. When the automatedly wound catheter is fed into the packaging bag, the wound catheter needs to be squeezed to form a long oval shape, reducing its overall width to facilitate feeding into the packaging bag.
[0004] However, when squeezing and winding the catheter, if the catheter is too long and the number of winding turns increases, the two ends will bulge and warp during squeezing, resulting in the inability to clamp the two ends during the clamping and conveying process, causing the wound catheter after squeezing to have a distance for reset extension, affecting the sleeving with the packaging bag. Summary of the Invention
[0005] The purpose of the present invention is to provide a medical catheter packaging device to solve the problem that in the process of packaging by existing automated packaging machines, due to excessive winding length, the clamping and conveying device cannot clamp the two ends, resulting in reset extension of the wound catheter.
[0006] The embodiments of the present invention are implemented through the following technical solutions:

[0009] Preferably, the sliding groove is several rectangular grooves arranged on the surface of the top of the packaging machine, and a toothed block is arranged on the surface of the middle part of the sliding groove near one end.
[0010] Preferably, the extrusion plate includes an inclined plate, a connecting shaft, an arc block and a transmission disc. A connecting shaft is arranged at the top of the extrusion plate. An inclined plate is arranged on one side of the connecting shaft. An arc block is connected between the inclined plate and the extrusion plate.

[0017] 1. The device is also provided with an abutting assembly. When the catheter is wound and then packaged, the abutting assembly can limit and apply pressure to the wound that is squeezed into a convenient shape for packaging, preventing the long and multi-turn winding catheter from deforming when being squeezed, which affects its clamping and conveying, and the sleeving with the packaging bag.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0027] The following will combine Figures 1 to 5 to make a detailed description of the present invention.
[0028] A medical catheter packaging device includes a catheter extruder 1. A first guide wheel 2 is arranged on one side of the catheter extruder 1. A cooling water tank 3 is arranged away from the catheter extruder 1 of the first guide wheel 2. A second guide wheel 4 is arranged on one side of the cooling water tank 3 away from the first guide wheel 2. A third guide wheel 5 is arranged on one side of the second guide wheel 4 away from the cooling water tank 3. A catheter horizontal clamping device 6 is arranged above the third guide wheel 5. A pipe coiling machine 7 is arranged on one side of the third guide wheel 5 away from the second guide wheel 4. A pipe coiling clamping machine 8 is arranged above the pipe coiling machine 7. A packaging machine 9 is arranged on one side of the pipe coiling machine 7. An open-bag device 10 is arranged on one side of the packaging machine 9 away from the pipe coiling machine 7. A shipping slide plate 11 is arranged on one side of the packaging machine 9 away from the pipe coiling machine 7. A abutting component is arranged on the top of the packaging machine 9, and the abutting component swings along the axis.
[0029] First, the produced catheter is extruded by the catheter extruder 1, and then driven by the first guide wheel 2 to enter the cooling water tank 3 for cooling. At the same time, the other end is connected to the second guide wheel 4, so that the catheter can be continuously conveyed in the cooling water tank 3 for cooling, and then continue to be conveyed through the third guide wheel 5. The end of the catheter is clamped by the catheter horizontal clamping device 6 and sent into the pipe coiling machine 7. The pipe coiling machine 7 clamps and then rotates, so that the catheter is wound around the pipe coiling machine 7 for winding and storage. The catheter is cut by the cutting device on the third guide wheel 5, and the wound catheter is clamped by the pipe coiling clamping machine 8 and sent into the packaging machine 9.
[0030] Then, the pushing device 901 in the packaging machine 9 is used to push the pressing plate 902 to close towards the center, and the wound catheter is pressed to form an oval strip. Then, the two ends of the oval strip formed by pressing are clamped by the clamping device 904 and conveyed into the conveying plate 905 for movement while maintaining its properties.
[0031] At the same time, at the other end, the open-bag device 10 is used to open the packaging bag, and then it is placed on the mouth-opening device, so that the catheter pressed into an oval strip in the conveying plate 905 can be conveniently fed through the opened annular packaging bag. Then, the catheter pressed into an oval strip is loosened to expand by its own elasticity, and the annular packaging bag is supported by applying force, so as to complete the packaging of the catheter. Then, it is sent to the shipping slide plate 11 through a clamping device to complete packaging and collection.
[0032] Furthermore, the abutment assembly includes a pushing device 901, an extrusion plate 902, a displacement groove 903, a clamping device 904, a conveying plate 905 and a slide groove 906. The pushing device 901 is arranged on both sides of the top of the packaging machine 9, the extrusion plate 902 is arranged on one side of the pushing device 901, the displacement groove 903 is arranged in the middle of the top of the packaging machine 9, the clamping device 904 is arranged in the displacement groove 903, the conveying plate 905 is arranged on the top of the packaging machine 9, and the slide groove 906 is arranged on the top surface of the packaging machine 9. The slide groove 906 is a plurality of rectangular grooves arranged on the top surface of the packaging machine 9, and a tooth block is arranged in the middle of the slide groove 906 near one end surface.
[0033] The abutment assembly is used to package some conduits that are longer, so that during extrusion packaging, the two ends are prone to bulge and tilt, affecting the clamping of the clamping device 904 on the two ends, thereby affecting the conveying and packaging of the conveying winding conduit.
[0034] Furthermore, the extrusion plate 902 includes an inclined plate 9021, a connecting shaft 9022, an arc block 9023 and a transmission disc 9024. The connecting shaft 9022 is arranged on the top of the extrusion plate 902, and the inclined plate 9021 is arranged on one side of the connecting shaft 9022. The arc block 9023 is connected between the inclined plate 9021 and the extrusion plate 902. The transmission disc 9024 is arranged at the bottom of the extrusion plate 902. The arc block 9023 is made of an elastic material with a certain hardness. The protruding part of the transmission disc 9024 cooperates with the slide groove 906 at the bottom of the extrusion plate 902, and the surface of the transmission disc 9024 is meshed with part of the tooth block of the slide groove 906.
[0035] When the wound conduit is sent between the extrusion plates 902 of the packaging machine 9, when the extrusion plates 902 are closed for pressing, the transmission disc 9024 at the bottom thereof will engage with part of the tooth blocks of the slide groove 906 and rotate. Because the transmission disc 9024 is connected to the belt drive of the connecting shaft 9022, when the transmission disc 9024 rotates, it will drive the connecting shaft 9022 to rotate together. When the connecting shaft 9022 rotates, it will drive the inclined plate 9021 on one side to deflect downward, thereby applying pressure to the raised parts on both sides when the winding conduit is squeezed, so that the two ends of the winding conduit will not be bulged toward the center, avoiding when the packaging length is long, so when the number of winding turns is too large, the two ends are prone to bulge and tilt during extrusion, so that the clamping device 904 can easily extend between the number of turns of the conduit winding, affecting its clamping.
[0036] Furthermore, the conveying plate 905 includes a connecting rod 9051, a deflection shaft 9052 and a support rod 9053. The protruding parts of the deflection shaft 9052 are arranged on both sides of the inner wall of the conveying plate 905, the connecting rod 9051 is arranged on the opposite side of the deflection shaft 9052, and the support rod 9053 is arranged on the side of the connecting rod 9051 away from the deflection shaft 9052. The two ends of the deflection shaft 9052 are connected to the conveying plate 905 through torsion springs, and the middle part of the support rod 9053 is a circular shaft with a movable connection.
[0037] At the same time, when the extruded winding conduit enters between the conveying plates 905, the two sides of one end thereof will abut against the supporting rod 9053. If the gap between the supporting rods 9053 is small, the supporting rod 9053 will be forced to link the connecting rod 9051 to drive the deflection shaft 9052 to a certain extent, thereby expanding the gap between the supporting rods 9053 to allow the winding conduit to pass through, and the restoring force generated by the springs at both ends of the deflection shaft 9052 will also exert pressure on the winding conduit in contact with the middle part, so that the winding conduit will not be too long due to the length of the winding, resulting in the extruded long ellipse also increasing in length, and the fixed spacing of the clamping device 904 cannot clamp to the two ends of the winding conduit extruded into the long ellipse, so that the winding conduit will have space to reset and expand again. Therefore, when passing between the conveying plates 905, it will reset and expand to increase its width, resulting in the inability to pass through the annular packaging bag for packaging.
[0038] The outermost support rod 9053 will be close to the bag opening device 10 when deflected, so that the winding conduit can maintain the required width for packaging when passing through the annular packaging bag.
[0039] The following is a specific process for implementing the present invention. First, the produced catheter is extruded through the catheter extruder 1, and then driven by the first guide wheel 2 to enter the cooling water tank 3 for cooling. At the same time, the other end is connected to the second guide wheel 4, so that the catheter can be continuously transported in the cooling water tank 3 for cooling, and then continue to be transported through the third guide wheel 5. The end of the catheter is clamped by the catheter transverse clamping device 6 and sent to the tube winding machine 7. The tube winding machine 7 is clamped and then rotated, so that the catheter is wrapped around the tube winding machine 7 for winding storage. The catheter is cut by the cutting device on the third guide wheel 5, and the wound catheter is clamped by the tube winding clamping machine 8 and sent to the packaging machine 9. Then, the extrusion plate is pushed by the pushing device 901 in the packaging machine 9. 902 is closed toward the center, and the conduit wound into a circle is compressed to form an elliptical strip. Then, the two ends of the conduit compressed into an elliptical strip are clamped by a clamping device 904, and the conduit is transported to a conveying plate 905 for movement while maintaining the properties. At the same time, the packaging bag is opened by a bag opening device 10 at the other end, and then prevented from reaching the opening device, so that the conduit compressed into an elliptical strip in the conveying plate 905 can be conveniently fed into the expanded annular packaging bag. Then, the conduit compressed into an elliptical strip is released to allow it to unfold through its own elasticity, and force is applied to support the annular packaging bag to complete the packaging of the conduit. Then, a clamping device is used to feed the conduit to a delivery slide 11 for packaging and collection. When the wound conduit is fed into When the extrusion plates 902 of the packaging machine 9 are closed for pressing, the transmission disc 9024 at the bottom thereof will mesh with some teeth of the slide groove 906 for rotation. Because the transmission disc 9024 is connected to the belt drive of the connecting shaft 9022, when the transmission disc 9024 rotates, it will drive the connecting shaft 9022 to rotate together. When the connecting shaft 9022 rotates, it will drive the inclined plate 9021 on one side to deflect downward, thereby applying pressure to the raised parts on both sides when the winding conduit is squeezed, so that the two ends of the winding conduit will not be raised close to the center, avoiding that when the packaging length is long, when the number of winding turns is too large, it is easy for the two ends to be raised and warped during extrusion, making the clamp The holding device 904 can easily extend into the space between the turns of the conduit winding, affecting its clamping. At the same time, when the extruded winding conduit enters between the conveying plates 905, the two sides of one end thereof will abut against the supporting rod 9053. If the gap between the supporting rods 9053 is small, the supporting rod 9053 will be forced to link the connecting rod 9051 to drive the deflection shaft 9052 to deflect to a certain extent, thereby expanding the gap between the supporting rods 9053 to allow the winding conduit to pass through, and the restoring force generated by the springs at both ends of the deflection shaft 9052 will also put pressure on the winding conduit in contact with the middle, so that the winding conduit will not be too long, resulting in the extruded long ellipse also increasing in length, and the fixed spacing of the clamping device 904 cannot clamp the very ends of the winding conduit extruded into the long ellipse.This allows the winding conduit to have space to reset and expand again. Therefore, when passing between the conveying plates 905, a reset expansion occurs to increase its width, resulting in the inability to pass through the annular packaging bag for packaging. When the outermost abutting rod 9053 deflects, it will approach the bag-opening device 10, enabling the winding conduit to maintain the required width when passing through the annular packaging bag for packaging.
[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention.
