Description

Technical Field

[0001] The utility model relates to the technical field of catheter production, in particular to a catheter feeding device and catheter production equipment. Background Art

[0002] In the production of medical catheters, it is necessary to cut the rolled catheters to a fixed length and transfer the cut catheters to a conveyor line for further processing by downstream equipment. The existing catheter feeding technology is provided with a feeding table in the discharge direction of the discharge port. The feeding table is provided with a receiving groove extending along the discharge direction of the catheter. The length of the receiving groove is the preset length of the catheter. The cut catheter is transported by the feeding table to the next station for subsequent processing. In this feeding technology, the cutting length of the catheter is easily limited by the feeding table. As the length requirement of the catheter increases, the width of the feeding table also needs to be increased accordingly, which undoubtedly increases the manufacturing cost, transportation cost and floor space of the entire catheter production equipment. Utility Model Content

[0003] In view of the fact that the existing catheter production equipment has the disadvantages of high cost and large floor space, it is necessary to provide a catheter feeding device and catheter production equipment with low production cost and small floor space.

[0004] A catheter feeding device, comprising:

[0005] a conveying assembly having a first conveying direction;

[0006] A delivery pipe assembly, the delivery pipe assembly is located on one side of the conveying assembly, and the delivery pipe assembly has a feed port and a second conveying direction perpendicular to the first conveying direction;

[0007] A pipe bending assembly, the pipe bending assembly is arranged at the feed port of the pipe delivery assembly and is used to bend the conduit so that one end of the conduit extending out of the feed port is directed toward the pipe delivery assembly;

[0008] a pipe cutting assembly, the pipe cutting assembly being arranged at the feed port and used for cutting the pipe so that the cut pipe has two ends facing the pipe delivery assembly; and

[0009] A transfer assembly is located above the transmission assembly, and has a transfer path with the feed port as a starting point for movement, and is used for transferring the cut catheter to the transmission assembly.

[0010] The catheter feeding device provided by the present application bends the catheter delivered by the tube feeding assembly through the bending assembly, and cooperates with the transfer assembly to transfer the catheter to the transmission assembly. On the one hand, the catheter feeding device does not need to set a separate accommodating groove for the cut catheter. Compared with the existing catheter feeding device, it saves a bearing device for receiving the cut catheter, reducing the production cost of the catheter feeding device; on the other hand, this bending method can also shorten the space occupied by the catheter in the entire catheter feeding device, thereby meeting the demand for longer catheter cutting lengths and expanding the use scenarios; in addition, the catheter feeding device provided by the present application does not need to design a longer accommodating groove to adapt to the demand for longer catheter cutting lengths, so it can also reduce the cost of equipment upgrades.

[0011] In one embodiment, the bending pipe assembly includes a first clamping member and a moving member, wherein the first clamping member is fixedly connected to the moving member, the first clamping member is used to clamp the catheter, and the moving member is used to drive the first clamping member to rotate a preset angle so that one end of the catheter extending out of the feed port is directed toward the feed port.

[0012] In this arrangement, the first clamping member clamps one end of the catheter extending out of the feed port and rotates under the drive of the moving member. This bending method of clamping and then rotating is beneficial to reducing the shaking of the catheter during the bending process, and protecting the catheter to avoid damage due to excessive local bending angles of the catheter.

[0013] In one embodiment, the moving member includes a mounting portion and a rotating portion, the first clamping member is mounted on the mounting portion, and a clamping position of the first clamping member and a rotation axis of the rotating portion are spaced apart.

[0014] With such an arrangement, the rotation angle of the first clamp is larger, which further reduces the local bending angle of the catheter, which is beneficial to protecting the catheter. At the same time, the bending tube assembly can adapt to longer catheter cutting length requirements.

[0015] In one embodiment, the delivery pipe assembly includes two conveying members and a driving member. The two conveying members are respectively abutted against two sides of the conduit and are driven in the same direction to form the feed port. The driving member is drivingly connected to at least one of the conveying members.

[0016] With such arrangement, the transmission member abuts against the catheter for transmission, so that the tube delivery assembly delivers the tube stably, which helps to prevent the tube from shaking when the tube cutting assembly cuts the tube, thereby improving the cutting accuracy.

[0017] In one embodiment, the tube delivery assembly further includes a moving sensor element that is synchronously driven with the transmission element, and the moving sensor element is used to measure the length of the delivered catheter.

[0018] With such arrangement, the moving sensor can measure the moving length of the conduit, which is beneficial for achieving precise feeding.

[0019] In one embodiment, the moving sensor comprises a roller and an encoder fixedly connected to the roller, and the roller abuts against the transmission member for transmission.

[0020] With such arrangement, the abutment transmission method can be accurately measured, the installation position can be adjusted, and the assembly is convenient.

[0021] In one embodiment, the moving sensor is a roller mounted with an encoder, and the roller is used to roll against the catheter.

[0022] In this way, the roller is arranged to slide directly against the catheter, so that the conveying length of the catheter can be directly measured, which is beneficial to improving the measurement accuracy of the encoder on the roller.

[0023] In one embodiment, the transmission element includes a synchronous belt and a plurality of rotating shafts, the synchronous belt is sleeved on the plurality of rotating shafts, the moving sensor element is an encoder, and the encoder is fixedly connected to the rotating shafts.

[0024] With this arrangement, multiple shafts are synchronously driven by synchronous belts, and the encoder can be installed on any one or more shafts, with various installation positions and flexible assembly.

[0025] In one of the embodiments, the tube delivery assembly further comprises a stopper, which is located between the two transmission members and is used to stop the catheter to prevent the catheter from slipping out of the tube delivery assembly laterally.

[0026] With such arrangement, the limiting member can timely correct the direction of the conduit between the two conveying members, effectively preventing the conduit from sliding laterally out of the conveying pipe assembly, thereby ensuring the stability of the feeding.

[0027] In one embodiment, the transfer assembly includes a shifting member and at least two second clamping members, wherein the two second clamping members are both installed on the shifting member and are respectively used to clamp the two ends of the cut catheter, and the shifting member is used to move the second clamping members along the transfer path to transfer the cut catheter to the transmission assembly.

[0028] With such arrangement, the two clamping members respectively fix the two ends of the catheter, thereby maintaining the bending shape of the catheter and preventing the catheter from shaking and falling during transportation.

[0029] In one embodiment, the second clamping member has a first clamping portion and a second clamping portion that are spaced apart along a feeding direction of the feeding tube assembly.

[0030] With such an arrangement, the two clamping parts clamping the catheter together can also reduce the bending of the catheter under the action of its own weight, further maintaining the stability of the shape of the catheter, thereby improving the stability of the catheter during transfer.

[0031] In one of the embodiments, the catheter feeding device further comprises a supporting member, which is disposed on a side of the tube cutting assembly relatively away from the feeding port and is used to support the catheter extending out of the feeding port.

[0032] With such arrangement, the supporting member is used to support the conduit, thereby reducing the bending of the conduit after it extends horizontally out of the feed port, which is beneficial to protecting the conduit and also facilitates the clamping of the second clamping member of the transfer assembly.

[0033] In one embodiment, the supporting member is provided with a guide groove toward the feed port, the guide groove having an inlet and an outlet which are away from each other, the inlet being located on a side of the guide groove relatively close to the tube cutting assembly for the catheter to enter the guide groove, and the outlet being used for the catheter to slide out.

[0034] With such arrangement, the guide groove can limit the shape of the catheter, so that the cut catheter remains parallel at both ends, thereby facilitating the grabbing by the second clamping member of the transfer assembly.

[0035] In one embodiment, the size of the inlet is larger than the size of the outlet.

[0036] Such an arrangement facilitates the catheter to extend into and pass through the guide groove, and prevents the catheter from being turned outward due to excessive resistance from the inner wall of the guide groove.

[0037] In one embodiment, the conveying assembly includes two layers of conveying tracks, a plurality of carriers installed on the two layers of conveying tracks, and a pushing member arranged at both ends of the two layers of conveying tracks. The pushing member drives the carriers located at both ends of the two layers of conveying tracks to drive the plurality of carriers to circulate between the two layers of conveying tracks.

[0038] With such arrangement, the transmission of multiple carriers on the two-layer conveying track can be realized by pushing the carriers at both ends of the two-layer conveying track through the pushing member, and the structure is simple and easy to implement.

[0039] In one embodiment, the pushing member includes a first pushing element that moves along the extension direction of the two layers of the conveying tracks and a second pushing element that moves vertically. The first pushing element abuts against the carrier to drive the carrier to slide along the two layers of the conveying tracks, and the second pushing element abuts against the bottom of the carrier to drive the carrier to switch between the two layers of the conveying tracks.

[0040] With such an arrangement, two pushing elements are used to realize the switching and translation of two carriers between two layers of conveying tracks. The two pushing elements have independent functions and a simple structure. The switching of the carriers can be realized by only programming and controlling the pushing cycles of the two pushing elements, which is conducive to reducing production costs.

The supporting member 60 is used to carry the catheter, which can reduce the bending of the catheter after it extends horizontally out of the discharge port 2612, is beneficial to protecting the catheter, and also facilitates the second clamping member 52 of the transfer assembly 50 to clamp the catheter.

[0095] Furthermore, in the above embodiment, the supporting member 60 is provided with a guide groove 61 facing the discharge port 2612, and the guide groove 61 has an inlet 611 and an outlet 612 which are separated from each other, the inlet 611 is located on the side of the guide groove 61 relatively close to the discharge port 2612 of the guide member 26 for the catheter to enter the guide groove 61, and the outlet 612 is used for the catheter to slide out. The guide groove 61 can limit the shape of the catheter, so that the cut catheter remains parallel at both ends, thereby facilitating the second clamping member 52 of the transfer assembly 50 to grab.

[0096] Furthermore, in another embodiment of the utility model, a plurality of guide grooves 61 are provided on the supporting member 60, and are used to correspond to the discharge ports 2612 of the plurality of pipe delivery assemblies 20, so that the conduits discharged from the discharge ports 2612 can be confined in the guide groove 61, and no interference will be generated between the conduits of two adjacent pipe delivery assemblies 20 when delivering the pipes.

[0097] Preferably, in an embodiment of the present invention, the size of the inlet 611 is larger than the size of the outlet 612. This facilitates the catheter to extend into and pass through the guide groove 61, and prevents the catheter from being turned outward due to excessive resistance from the inner wall of the guide groove 61.

[0098] Optionally, in one embodiment of the utility model, the conveying assembly 10 includes two layers of conveying tracks, a plurality of carriers 11 installed on the two layers of conveying tracks, and a pusher 12 disposed at both ends of the two layers of conveying tracks, and the pusher 12 drives the carriers 11 located at both ends of the conveying tracks to drive the plurality of carriers 11 to circulate and rotate between the two layers of conveying tracks. The transmission of the plurality of carriers 11 on the two layers of conveying tracks can be realized by pushing the carriers 11 at both ends of the conveying tracks by the pusher 12, and the structure is simple and easy to implement.

[0099] Furthermore, in the above embodiment, the transfer assembly 50 also includes a tube pressing member 53 disposed at the second clamping member 52 . When the transfer assembly 50 transfers the cut catheter to the carrier 11 on the transmission assembly 10 , the tube pressing member 53 can press the catheter to fix the catheter to the carrier 11 .

[0100] Specifically, in the above embodiment, the pusher 12 includes a first pusher element moving along the extension direction of the conveying track and a second pusher element moving vertically, the first pusher element abuts against the carrier 11 to drive the carrier 11 to slide along the conveying track, and the second pusher element abuts against the bottom of the carrier 11 to drive the carrier 11 to switch between the two layers of conveying tracks. The two pushers have independent functions and a simple structure, and the switching of the carrier 11 can be achieved by programming and controlling the pushing cycle of the two pushers, which is conducive to reducing production costs.
