Description

Technical Field

[0001] The present invention relates to the technical field of medical device production fixtures, and particularly to a heat shrink tube peeling device. Background Art

[0002] Medical catheters are important devices for minimally invasive interventional therapy. During the production process of catheters, it is necessary to splice or combine tube bodies of different materials or outer diameters. A heat shrink tube is nested on the outer surface of the tube body for hot melting. After the catheter is assembled, the heat shrink tube needs to be removed and peeled off, and thus a heat shrink tube peeling device is required.

[0003] The existing heat shrink tube peeling device uses a strip-shaped groove with a dovetail groove structure in a tube clamping seat to clamp the catheter to be peeled to prevent the catheter from slipping during the peeling process. Then, after the heat shrink tube is separated by a tool, the heat shrink tube is peeled off manually. The problems of the existing heat shrink tube peeling device are: lack of fixation of the tool and adjustment of the feed amount of the tool, which reduces the stability and peeling quality during the peeling process. At the same time, the feed amount of the tool during the peeling process is likely to change, resulting in scratching of the catheter and reducing the safety of the catheter.

[0004] Therefore, there is an urgent need for a heat shrink tube peeling device to solve the above problems. Summary of the Invention

In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0040] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0041] The problems existing in the existing heat shrinkable tube stripping device are as follows: there is a lack of fixation of the cutting tool and adjustment of the feed amount of the cutting tool, which reduces the stability and stripping quality during the stripping process. At the same time, the feed amount of the cutting tool during the stripping process is likely to change, resulting in scratches on the catheter and reducing the safety of the catheter.

[0042] To solve the above problems, as shown in Figure 1 and Figure 2 This embodiment provides a heat shrink tube stripping device, which includes a base frame 1, a mounting frame 2, an angle frame 3, a cutter 4, a first adjusting rod 5, a measuring mechanism 6 and a second adjusting rod 7. The conduit 100 can pass through the stripping station of the base frame 1. The mounting frame 2 is vertically movably arranged on the base frame 1. The cutter 4 is rotatably arranged on the angle frame 3 and can strip the heat shrink tube outside the conduit 100. The angle frame 3 is arranged on the mounting frame 2 and can measure the rotation angle of the cutter 4. The first adjusting rod 5 is connected to the mounting frame 2 to adjust the height of the mounting frame 2. The measuring mechanism 6 is arranged on the base frame 1 and can measure the lifting displacement of the mounting frame 2. The second adjusting rod 7 is arranged on the mounting frame 2 and is in transmission connection with the cutter 4 to adjust the rotation angle of the cutter 4. The first adjusting rod 5 adjusts the height of the cutter 4 through the mounting frame 2. At the same time, the measuring mechanism 6 can measure the lifting displacement of the mounting frame 2 to accurately adjust the height of the cutter 4. The second adjusting rod 7 adjusts the rotation angle of the cutter 4. At the same time, the angle frame 3 can measure the rotation angle of the cutter 4 to accurately adjust the angle of the cutter 4, so that the heat shrink tube stripping device realizes the adjustment of the height and angle of the cutter 4, thereby improving the accurate adjustment of the feed amount of the cutter 4 during the stripping process. When the cutter 4 cuts the heat shrink tube outside the conduit 100, it can also avoid scratching the conduit 100, improving the stripping quality and the safety of the conduit 100. The above feed amount is the cutting depth of the cutter 4 on the conduit 100, and the feed amount is approximately equal to the wall thickness of the heat shrink tube to ensure that the cutter 4 can strip the heat shrink tube while avoiding scratching the conduit 100.

[0043] When stripping the heat shrink tube, place the conduit 100 to be stripped at the stripping station of the base frame 1. First, adjust the height of the mounting frame 2 through the first adjusting rod 5, so that the cutting edge of the cutter 4 abuts against the heat shrink tube outside the conduit 100. Then, adjust the rotation angle of the cutter 4 through the second adjusting rod 7, so that the cutting edge of the cutter 4 presses tightly against the heat shrink tube. It should be noted that at this time, the cutting edge of the cutter 4 can be pressed into the heat shrink tube. When the conduit 100 is manually pulled, the cutting edge of the cutter 4 can cut the heat shrink tube, forming a cut in the heat shrink tube, so as to facilitate the stripping of the heat shrink tube from the conduit 100.

[0044] As shown in Figure 1 In this embodiment, the cutting edge of the cutter 4 is perpendicular to the axial direction of the conduit 100 and is inclinedly installed on the angle frame 3, so that the cutter 4 can form a cut with a certain width on the heat shrink tube, reducing the difficulty of later manual stripping and improving the stripping efficiency of the heat shrink tube.

[0045] As shown in Figure 1 and Figure 2As shown, the seat frame 1 includes a bottom plate 11, guide posts 12 and a top plate 13. There is a stripping station on the bottom plate 11. The guide posts 12 are arranged vertically on the bottom plate 11 and support the top plate 13. The mounting frame 2 includes a connected slider 21 and a support plate 22. The slider 21 is sleeved on the guide post 12 in a liftable manner. The first adjusting rod 5 movably passes through the top plate 13 and is connected to the support plate 22. The slider 21 is in sliding fit with the guide post 12, so that the guide post 12 plays a guiding and limiting role in the lifting movement of the slider 21 in the vertical direction, improving the stability of the lifting movement of the slider 21, and thus improving the height adjustment accuracy of the tool 4.

[0046] In this embodiment, there are two guide posts 12, and the slider 21 and the support plate 22 also have two respectively. The two guide posts 12 are arranged at intervals in the vertical direction on the bottom plate 11, and the tops of the two guide posts 12 jointly support the top plate 13. The two sliders 21 are respectively sleeved on the corresponding guide posts 12 in a sliding manner and are connected into a whole through a vertically placed support plate 22 to realize the synchronous lifting movement of the two sliders 21. Another support plate 22 is horizontally placed between the two sliders 21 and is fixedly connected to the vertically placed support plate 22. The first adjusting rod 5 passes through the top plate 13 and is connected to the horizontally placed support plate 22.

[0047] Specifically, a first hole 131 is opened on the top plate 13, and the first adjusting rod 5 is threadedly connected to the first hole 131. By screwing the first adjusting rod 5 clockwise or counterclockwise, the lifting movement of the mounting frame 2 can be realized, making the height adjustment operation of the tool 4 simple and easy, and improving the adjustment efficiency. For example, when the first adjusting rod 5 is screwed clockwise, the first adjusting rod 5 drives the slider 21 to move downward along the corresponding guide post 12 through the two support plates 22 to reduce the height of the tool 4. When the first adjusting rod 5 is screwed counterclockwise, the first adjusting rod 5 drives the slider 21 to move upward along the corresponding guide post 12 through the two support plates 22 to increase the height of the tool 4.

[0048] It should be noted that since the first adjusting rod 5 is threadedly connected to the first hole 131, when the height adjustment of the tool 4 is in place (at this time, the cutting edge of the tool 4 abuts against the outer surface of the heat shrinkable tube), self-locking can be achieved through the thread on the first adjusting rod 5 to keep the height of the tool 4 stable.

[0049] Furthermore, the heat shrinkable tube stripping device further includes a locking rod 8. A second hole communicating with the corresponding guide post 12 is opened on the slider 21, and the locking rod 8 is threadedly connected to the second hole so that one end of the locking rod 8 abuts against or disengages from the guide post 12. When the locking rod 8 is screwed clockwise and the end of the locking rod 8 abuts tightly against the guide post 12, the locking rod 8 can lock the relative position of the slider 21 and the guide post 12. When the locking rod 8 is screwed counterclockwise and the end of the locking rod 8 is disengaged from the guide post 12, the locking rod 8 can unlock the slider 21 and the guide post 12.

[0050] As Figure 2 shown, the mounting bracket 2 further includes a top rod 14, and the top rod 14 is disposed on the slider 21. The measuring mechanism 6 is a dial indicator, and the dial indicator is disposed on the top plate 13 and the measuring head of its measuring rod abuts against the top rod 14. The dial indicator can accurately measure the height change of the cutting tool 4, which is beneficial to improving the height adjustment accuracy of the cutting tool 4. Of course, the measuring mechanism 6 can also be other instruments such as a rangefinder, etc., which is not specifically limited herein.

[0051] Specifically, the measuring rod of the dial indicator is always in a compressed state. Under the action of the first adjusting rod 5, when the slider 21 drives the cutting tool 4 to rise or fall, the measuring rod of the dial indicator synchronously contracts or extends the same distance, and is accurately displayed on the dial of the dial indicator, so as to facilitate the operator to view in real time and improve the height adjustment accuracy of the cutting tool 4.

[0052] As Figure 1 shown, the heat shrink tube stripping device further includes a transfer bracket 9. One end of the transfer bracket 9 is rotatably disposed on the angle bracket 3, and the other end extends to the stripping station and is provided with a cutting tool 4. A third hole 221 is formed in the mounting bracket 2 (the horizontally placed support plate 22), and the second adjusting rod 7 is threadedly connected to the third hole 221 and connected to the transfer bracket 9. By adjusting the angle of the cutting tool 4, the pressing force between the cutting tool 4 and the heat shrink tube can be adjusted, so that the cutting tool 4 can avoid scratching the conduit 100 inside the heat shrink tube while cutting the heat shrink tube.

[0053] After the angle adjustment of the cutting tool 4 is completed, the rotation angle of the cutting tool 4 can be adjusted by screwing the second adjusting rod 7 clockwise or counterclockwise, making the angle adjustment operation of the cutting tool 4 simple and easy, and improving the adjustment efficiency. For example, when the second adjusting rod 7 is screwed clockwise, the second adjusting rod 7 drives the cutting tool 4 to rotate clockwise relative to the angle bracket 3 through the transfer bracket 9, so that the cutting edge of the cutting tool 4 abuts against and presses into the heat shrink tube. When the second adjusting rod 7 is screwed counterclockwise, the second adjusting rod 7 drives the cutting tool 4 to rotate counterclockwise relative to the angle bracket 3 through the transfer bracket 9, thereby reducing the pressing force between the cutting edge of the cutting tool 4 and the heat shrink tube, and avoiding the cutting edge of the cutting tool 4 from simultaneously abutting against the conduit 100 and causing the conduit 100 to be scratched.

[0054] As Figure 1As shown in the figure, the adapter bracket 9 includes a main frame body 91, a rotating shaft 92, a slide bar 94 and two clamping pieces 93. One end of the main frame body 91 is pivotally connected to the angle bracket 3 through the rotating shaft 92. The other end of the main frame body 91 is connected with two clamping pieces 93. The two clamping pieces 93 are arranged oppositely and can clamp the tool 4. The angle bracket 3 is a U-shaped frame. The first side plate of the U-shaped frame is fixedly installed on the vertically placed support plate 22. Angle scale lines are engraved on the outer side of the second side plate of the U-shaped frame. At the same time, arc-shaped chutes 31 are opened on both side plates of the U-shaped frame. The angle scale lines and the chute 31 of the second side plate are concentrically distributed. The main frame body 91 is pivotally connected to the two side plates of the U-shaped frame through the rotating shaft 92. There are two slide bars 94. The two slide bars 94 are arranged oppositely at both ends of the main frame body 91 and respectively penetrate into the two chutes 31. Through the sliding fit of the slide bar 94 and the chute 31, it can play a guiding and limiting role in the rotation process of the main frame body 91, and improve the stability of the angle adjustment process of the tool 4. One of the two clamping pieces 93 is fixedly installed on the main frame body 91 and is connected to the other clamping piece 93 through a bolt, so that the two clamping pieces 93 can clamp the tool 4, ensuring the stability of the tool 4 during the heat shrinkable tube stripping process. At the same time, the detachable installation of the two clamping pieces 93 can be realized, which is convenient for the replacement of the tool 4 and improves the disassembly and assembly efficiency of the tool 4.

[0055] In order to facilitate the accurate observation of the rotation angle of the tool 4, the adapter bracket 9 further includes a pointer 95. One end of the pointer 95 is connected to the main frame body 91, and the other end points to the angle scale line. The pointer 95 can rotate synchronously with the main frame body 91 to display the rotation angle of the tool 4 in real time, which is convenient for the operator to view and improves the angle adjustment accuracy of the tool 4.

[0056] As Figure 1 and Figure 3 As shown in the figure, the heat shrinkable tube stripping device further includes a clamping mechanism 10. The clamping mechanism 10 includes a bearing plate 101 and a pressing block 102. The bearing plate 101 is arranged at the stripping station and extends with a boss 1011. A first groove is opened on the boss 1011. A second groove is correspondingly opened on the pressing block 102 and is detachably arranged on the boss 1011, so that the first groove and the corresponding second groove enclose a stripping channel 103 for the catheter 100 to pass through.

[0057] Specifically, the carrier plate 101 is fixedly installed on the stripping station of the bottom plate 11 by bolts. The pressing block 102 and the boss 1011 are also fixedly connected by bolts, facilitating the quick disassembly and assembly of the pressing block 102. Three first grooves are provided on the boss 1011 of this embodiment, and three corresponding second grooves are provided on the pressing block 102. When the pressing block 102 is installed on the boss 1011, three stripping channels 103 can be formed, that is, the heat shrinkable tubes of three conduits 100 to be stripped can be stripped simultaneously, improving the stripping efficiency of the heat shrinkable tube stripping device. In other embodiments, the number of the formed stripping channels 103 can also be adjusted to other numbers, such as one, two, four, etc., which are not specifically limited herein.

[0058] Further, as Figure 3 shown, the clamping mechanism 10 further includes a mandrel 104. The mandrel 104 is clamped in the stripping channel 103 and a through hole is axially provided therein. The conduit 100 can pass through the through hole. A stripping groove 1041 communicating with the through hole is provided on the mandrel 104. The cutting edge of the tool 4 can extend into the stripping groove 1041 to strip the heat shrinkable tube outside the conduit 100. When the pressing block 102 and the boss 1011 are locked by bolts, the mandrel 104 can be fixed in the corresponding stripping channel 103. It should be noted that the length of the mandrel 104 is much greater than the length of the stripping channel 103, so that the mandrel 104 extends the actual length of the stripping channel 103, which is beneficial to reducing the sizes of the boss 1011 and the pressing block 102, and realizing the compact assembly of the clamping mechanism 10. Since the length of the mandrel 104 is long and the cutting edge of the tool 4 cuts the heat shrinkable tube in the stripping groove 1041 of the mandrel 104, the conduit 100 to be stripped can always maintain the same height during the stripping process, locking the relative positions of the conduit 100 to be stripped and the tool 4, realizing precise stripping, avoiding the bending of the conduit 100 to be stripped and other situations that may cause the conduit 100 to be scratched, and improving the stripping quality and the safety of the conduit 100.

[0059] The above embodiments only illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, there are various changes and modifications to the present invention, and these changes and modifications all fall within the scope of the present invention claimed.
