Description

Technical Field

[0001] The utility model relates to the technical field related to cutting of indwelling needle cannulas, in particular to a fixed-length cutting tool for indwelling needle cannulas. Background Art

[0002] At present, when domestic enterprises process indwelling needle cannulas, large enterprises generally use automated equipment to cut and process indwelling needle cannulas, while small enterprises have limited funds, and most of them generally use manual comparison and scissors to cut, which uses a lot of manpower for production, with extremely low production efficiency, and the length of the cannula after cutting is unstable and the defective rate is high. Therefore, how to design a tooling that can meet the needs of small enterprises to process indwelling needle cannulas and improve the yield rate of indwelling needle cannulas has become a technical problem that needs to be solved urgently. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of the utility model is to provide a fixed-length cutting tool for an indwelling needle cannula to solve the above-mentioned technical problems.

[0004] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0005] According to one aspect of the utility model, a fixed-length cutting tool for an indwelling needle cannula is designed, comprising:

[0006] The tooling table is provided with a material drop opening, and a support column is fixedly connected to the bottom of the tooling table;

[0007] The fixed length piece is L-shaped and has a positioning surface on the right side. The fixed length piece is fixed to the workbench by bolts, and the right end is located above the blanking opening. The fixed length piece is provided with an adjustment mounting hole for horizontally adjusting the fixing position thereof;

[0008] A cutting seat is arranged on the right side of the fixed length piece and is fixedly connected to the workbench. A longitudinal slit running through the cutting seat is arranged on the upper part thereof and a transverse slit running through the cutting seat is arranged on the upper part thereof. The transverse slit is perpendicular to the positioning surface.

[0009] A cutting knife, the lower portion of which is placed in the longitudinal slit;

[0010] The driving device is fixedly connected to the tooling table through the first mounting seat. The driving device is connected to the cutting knife for driving the cutting knife to move longitudinally to cut the indwelling needle cannula.

[0011] By adopting the above technical scheme, when the cannula of the indwelling needle needs to be cut to a fixed length, one end of the cannula is passed through the horizontal gap from the right side of the cutting seat to the left, and then the end of the cannula is brought into contact with the positioning surface to achieve the fixed length of the cannula. Then the driving device starts to drive the cutting knife to move forward, and the cutting knife cuts the cannula. Then the driving device drives the cutting knife to reset. Through this tooling, the length of the cannula after cutting can be guaranteed to be consistent and stable, thereby improving the yield rate of the cannula processing. In addition, by providing an adjustment mounting hole on the fixed-length piece for laterally adjusting its fixed position, the fixed-length piece can be adjusted left and right, and the distance between the positioning surface on its right side and the longitudinal gap can be adjusted to meet the needs of cutting and processing cannulas of different lengths, thereby improving the practicality of this tooling.

[0012] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0013] In some embodiments, a counting device is further included, the counting device including a counter, a magnetic induction switch and a magnet block, the counter is mounted on the tooling table, the magnetic induction switch is located on the right side of the cutting knife and is fixed to the tooling table through a second mounting seat, the magnetic induction switch and the counter are electrically connected through a data line, the magnet block is mounted on the cutting knife and corresponds to the left and right of the magnetic induction switch. In this way, the number of times the cutting knife moves can be counted, thereby realizing the counting of the number of cut sleeves.

[0014] In some embodiments, a material rack is further included, the material rack including a base, a bracket fixed to the base, a rotating wheel rotatably matched with the bracket, and a plurality of fixing rods circumferentially distributed on the rotating wheel. A sleeve can be sleeved through the fixing rods on the rotating disk, and the rotating disk and the bracket rotatably match to facilitate pulling and loosening of the sleeve.

[0015] In some embodiments, the cutting seat is provided with a blind hole having a diameter greater than the width of the transverse slit, and the lower portion of the transverse slit extends into the blind hole. If the transverse slit is slightly larger than the diameter of the sleeve, it is not easy for the sleeve to pass through when it passes from the right side of the transverse slit to the left side without a blind hole. By providing a blind hole having a diameter greater than the width of the transverse slit, and the lower portion of the transverse slit extending into the blind hole, the sleeve passes from the right side of the blind hole to the left side, and then passes out from the transverse slit on the left side, so that the sleeve can pass through easily.

[0016] In some embodiments, the blind hole extends to the left side of the longitudinal slit.

[0017] In some embodiments, the cutting knife includes a cutting blade and two clamping plates for clamping and fixing the cutting blade, the lower portion of the cutting blade is placed in the longitudinal gap, the two clamping plates are fixed by bolts, and the clamping plates are connected to the driving end of the driving device.

[0018] In some embodiments, the driving device is a cylinder. BRIEF DESCRIPTION OF THE DRAWINGS
