Description

Technical Field

[0001] The utility model relates to the technical field of wire polishing, in particular to a medical metal wire polishing machine. Background Technique

[0002] Medical metal wires are important materials used to manufacture medical devices and equipment. Common types include stainless steel, titanium alloy, nitinol alloy, and aluminum alloy. These metal wires possess excellent mechanical properties, corrosion resistance, and biocompatibility, and are widely used in fields such as surgical instruments, implants, and catheters to ensure the safety and effectiveness of medical devices.

[0003] The patent document with the publication number CN210160932U in the prior art provides a metal wire polishing machine. In this metal wire polishing machine, a fixed column is fixedly connected to the upper surface of the fixed plate. A first rotating motor is fixedly connected to the left side surface of the fixed column. A first bearing is fixedly embedded in the lower part of the left side surface of the fixed column. The output end of the first rotating motor is fixedly connected to a first rotating rod. The end of the first rotating rod away from the first rotating motor penetrates through the first bearing and extends to the right side of the first bearing. The above structure plays a role in adjusting the second rotating motor through the sliding of the sliding plate, avoiding the problem that the current polishing machine used for metal wires does not have the function of adjusting the distance between the two polishing wheels. Although this device has many beneficial effects, there are still the following problems: when the wire is wound onto the second wire reel after polishing, the powder generated by polishing carried on the wire is prone to accumulate on the second wire reel, and then the wire reel wound by the second wire reel has more powder, resulting in poor cleanliness of the wire reel. For this reason, we propose a medical metal wire polishing machine. Content of the Utility Model

[0004] The purpose of the utility model is to provide a medical metal wire polishing machine to solve the problem that the powder generated by polishing carried on the wire is prone to accumulate on the second wire reel as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A medical metal wire polishing machine, comprising:

[0006] A fixed plate, a support plate is arranged on the top of the fixed plate, and a first wire reel and a second wire reel are arranged on the side wall of the support plate;

[0007] A horizontal plate is provided on the side wall of the support plate. A driving motor is provided on the top of the horizontal plate. A polishing disc is provided at the power output end of the driving motor. A wire passing hole is formed in the top of the horizontal plate. A fixing ring matching the wire passing hole is provided at the bottom of the horizontal plate. A rubber tube is provided at the bottom of the fixing ring. A bottom ring is provided at the bottom of the rubber tube. An air suction member is provided outside the bottom ring. A hard tube is provided at the output end of the air suction member. A connecting cylinder I is provided at the output end of the hard tube. A connecting cylinder II is provided on the side wall of the connecting cylinder I. A dust-proof net is provided inside the connecting cylinder II;

[0008] Support columns are fixedly connected to the bottom of the horizontal plate. A servo motor is fixedly connected to the side wall of the support column. A screw rod is provided at the power output end of the servo motor. A displacement block is sleeved outside the screw rod. A sliding block is provided on the side wall of the displacement block.

[0009] Preferably, a diagonal support plate is provided on the side wall of the support plate.

[0010] Preferably, the sliding block is fixedly connected to the side wall of the displacement block.

[0011] Preferably, a limiting column penetrates through the side wall of the sliding block.

[0012] Preferably, the limiting column is fixedly connected to the side wall of the support column.

[0013] Preferably, an external tube is provided at the output end of the connecting cylinder II.

[0014] Preferably, the bottom ring is matched with the top of the second wire reel.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. By providing a bottom ring with a rubber tube at the bottom of the horizontal plate, after the wire passes through the polishing disc for polishing and enters the inside of the wire passing hole, the wire is matched with the inside of the rubber tube and the bottom ring. When the external air pump connected to the external tube operates, the air inside the connecting cylinder II is pumped outwards. At this time, the air suction member sucks the outer wall of the wire inside the bottom ring, so that the powder generated by the polishing of the outer wall of the wire is sucked into the inside of the air suction member. Then, the powder enters the inside of the connecting cylinder I and the connecting cylinder II along with the air flow through the hard tube, and the powder is intercepted by the dust-proof net inside the connecting cylinder II. Thus, it can realize the cleaning and collection of the powder generated by the grinding of the outer wall of the wire, avoid the powder on the outer wall of the wire from accumulating on the second wire reel when the second wire reel collects the wire, and is beneficial to improving the cleanliness of the wire wound by the second wire reel.

[0017] 2. When dust removal is carried out inside the bottom coil of the wire, the servo motor operates to rotate the screw, and then the displacement block uses the sliding block to slide and limit on the limiting column and displace outside the screw, prompting the bottom coil to displace. At this time, the wire is driven by the bottom coil to be deflected, so that the winding position of the wire on the second wire reel can be changed, avoiding the problem that the wire accumulates at the same position when wound on the second wire reel, resulting in an uneven outer surface of the wire reel after winding, and making the wire reel formed after winding the wire more flat.

[0035] Working principle: By setting a bottom ring 240 with a rubber tube 233 at the bottom of the cross plate 200, after the wire passes through the polishing disc 220 for polishing and enters the inside of the wire threading hole 230, the wire fits inside the rubber tube 233 and the bottom ring 240. The external air pump connected to the external tube 253 operates to pump the air inside the connecting cylinder two 251 outwards. At this time, the suction part 241 sucks the outer wall of the wire inside the bottom ring 240, so that the powder generated by the polishing on the outside of the wire is sucked into the inside of the suction part 241. Then, the powder enters the inside of the connecting cylinder one 250 and the connecting cylinder two 251 along with the air flow through the hard tube 242, and the powder is intercepted by the dust screen 252 inside the connecting cylinder two 251. Thus, it can realize the cleaning and collection of the powder generated by the grinding on the outer wall of the wire, and avoid the powder on the outer wall of the wire from accumulating on the second wire reel 130 when the second wire reel 130 collects the wire, which is beneficial to improving the cleanliness of the wire wound on the second wire reel 130; when the wire is dust-removed inside the bottom ring 240, the servo motor 310 operates to rotate the screw 311, and then the displacement block 320 uses the sliding block 330 to slide and be limited on the limiting column to displace outside the screw 311, prompting the bottom ring 240 to displace. At this time, the wire is driven by the bottom ring 240 to be deflected, so that it can realize the change of the winding position of the wire on the second wire reel 130, and avoid the problem that the wire accumulates at the same position when wound on the second wire reel 130, resulting in an uneven appearance of the wire reel after winding, and making the wire reel formed after the wire is wound smoother.
