DETAILED DESCRIPTION
[0029] In order to make the technical personnel in the art better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor should belong to the scope of protection of the present application.
[0030] As Figures 1-5As shown, a surgical suture extrusion device according to one embodiment of the present invention includes a frame 1 and an extruder body 3. The extruder body 3 is fixedly installed on the top of the frame 1. A screw is rotatably installed inside the extruder body 3. A die head 4 is fixedly installed at one end of the extruder body 3, and the surgical suture is extruded and formed through the die head 4. A motor 2 is installed at the other end of the extruder body 3. The motor 2 is fixedly installed on the top of the frame 1, and the output end of the motor 2 is fixed to one end of the screw. The motor 2 can drive the screw to rotate, thereby pushing the material for preparing the surgical suture to move inside the extruder body 3.
[0031] A feed inlet is provided on the top of the extruder body 3 near the motor 2. A hopper 5 is fixedly installed above the feed inlet. The plastic material for preparing surgical sutures is stored inside the hopper 5 and continuously enters the interior of the extruder body 3 through the feed inlet under the action of gravity, thus realizing automatic feeding.
[0032] like Figure 4 and Figure 5 As shown, a support plate 6 is fixedly installed at the top of the hopper 5, and a sleeve 11 is fixedly installed at the center of the support plate 6. A rotating cylinder 10 is rotatably installed inside the sleeve 11. The outer wall of the rotating cylinder 10 is provided with a boss 1002, and the inner wall of the sleeve 11 is provided with a groove 1101. The boss 1002 is embedded in the groove 1101, which can limit the rotating cylinder 10 and prevent the rotating cylinder 10 from sliding up and down during rotation.
[0033] like Figure 2 and Figure 4 As shown, a central shaft 7 is installed through the inside of the rotating drum 10. The central shaft 7 is fixed to the rotating drum 10, meaning that the central shaft 7 can rotate arbitrarily. An anti-blocking block is fixedly installed at the bottom end of the central shaft 7. The anti-blocking block includes a first block 8 and a second block 9. The first block 8 is fixedly installed at the bottom end of the central shaft 7 and is a right conical shape, which will not obstruct the downward flow of material inside the hopper 5. The second block 9 is fixedly installed at the bottom end of the first block 8 and is an inverted conical shape. A discharge channel 501 is reserved between the outer wall of the second block 9 and the inner wall of the hopper 5, allowing material to flow downward through the discharge channel 501.
[0034] When there are excessively large material blocks, they cannot pass through the feeding channel 501, thus intercepting the excessively large material blocks and preventing them from clogging the feed inlet, ensuring the normal operation and production efficiency of the extruder. At the same time, by rotating the central shaft 7, the first block 8 and the second block 9 can be driven to grind and crush the excessively large material blocks intercepted, thereby facilitating the subsequent processing of the material.
[0035] A crank 701 is fixedly installed at the top of the central shaft 7, which allows for easy manual rotation of the central shaft 7 and facilitates operation.
[0036] As Figure 3 shown, the drum 10 is fixedly installed with a socket 1001, the socket 1001 is inserted with a plug rod 13, one end of the plug rod 13 penetrates to the inside of the drum 10.
[0037] A plurality of adjustment holes 702 are formed on the central shaft rod 7 near the top, the plug rod 13 can be inserted into the adjustment hole 702, and the limiting fixation between the central shaft rod 7 and the drum 10 is realized. After the plug rod 13 is pulled out, the central shaft rod 7 and the drum 10 lose the limiting fixation, and the central shaft rod 7 can slide up and down in the drum 10, so as to adjust the height of the first block 8 and the second block 9. By adjusting the height of the first block 8 and the second block 9, the width of the discharging channel 501 can be adjusted, so as to adjust the discharging speed, so as to adapt to various needs.
[0038] It is worth noting that when the first block 8 and the second block 9 are lowered to the bottom end, the hopper 5 can be sealed, so as to facilitate the control of the material supply.
[0039] Preferably, the plurality of adjustment holes 702 are arranged at equal intervals, and the quantitative adjustment of the height of the first block 8 and the second block 9 can be realized.
[0040] As Figure 3 shown, one end of the plug rod 13 is fixedly installed with a handle 1301, and the plug rod 13 is conveniently pulled out through the handle 1301. The spring 12 is fixedly installed between the handle 1301 and the socket 1001, the plug rod 13 can be elastically pulled out through the spring 12, the plug rod 13 is prevented from being naturally pulled out, the stability of the structure is ensured, and the adjustment operation is facilitated.
[0041] In use, the plastic material for preparing surgical sutures is stored in the hopper 5 and continuously flows into the feed inlet through the discharging channel 501, at this time, the oversized material blocks cannot pass through the discharging channel 501 and are intercepted, and every time interval, the central shaft rod 7 is rotated through the crank 701, so that the first block 8 and the second block 9 crush the intercepted oversized material blocks, and the convenient processing of the oversized material blocks is realized.
[0042] When the discharging rate needs to be adjusted, the handle 1301 is pulled to pull out the plug rod 13, at this time, the central shaft rod 7 loses the limiting with the drum 10, so that the central shaft rod 7 can be adjusted up and down, so as to adjust the height of the first block 8 and the second block 9, and then adjust the width of the discharging channel 501, so as to adjust the discharging rate. After the adjustment is completed, the handle 1301 is loosened, the plug rod 13 automatically enters the corresponding adjustment hole 702, and the limiting fixation between the central shaft rod 7 and the drum 10 is realized again.
[0043] Compared with the prior art, the surgical suture extrusion equipment can prevent the oversized material block from blocking the feeding port through the anti-blocking block, ensure normal discharging of the extruder, guarantee normal operation and production efficiency of the extruder; meanwhile, the oversized material block can be collected and crushed for treatment, and subsequent processing of the material is facilitated.
[0044] It is apparent for a person skilled in the art that the present application is not limited to the details of the above exemplary embodiments but can be implemented in other embodiments without departing from the scope of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the present application being defined by the appended claims rather than the above description, and it is intended to embrace all changes and modifications that fall within the meaning and scope of equivalents of the claims. Any reference signs in the claims should not be construed as limiting the claims to the figures in which the reference signs are used.
[0045] Furthermore, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the specification is described in this way only for the sake of clarity, and a person skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by a person skilled in the art.
