Description

Technical Field

[0001] This utility model belongs to the technical field of medical plastic pipe processing equipment, specifically a chamfering device for the end of medical plastic pipes. Background Technology

[0002] Medical plastic tubing refers to tubular instruments or components made of plastic materials that meet medical-grade standards, used for various fluid transport, diagnosis, treatment, interventional procedures, and other purposes in the medical field.

[0003] When chamfering the ends of medical plastic tubing, chamfering devices are frequently used. While existing chamfering devices can perform basic chamfering functions, they suffer from insufficient flexibility. Due to the wide variety of specifications of medical plastic tubing, some short-length tubing has limited length, making it difficult to reach the effective processing position of the chamfering device. Consequently, the chamfering device cannot reach the end of the tubing for processing. To complete the chamfering of such tubing, operators have to frequently change specialized chamfering equipment. This not only significantly increases equipment procurement and maintenance costs but also causes a significant decrease in production line efficiency due to the time spent on equipment switching, seriously affecting production progress and economic benefits. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a chamfering device for the end of medical plastic tubing, which has the advantage of wide applicability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a chamfering device for the end of a medical plastic tube, including a support leg 1, a workbench 2 fixedly connected to the top of the support leg 1, a movable plate 3 movably connected inside the workbench 2, a drive motor 4 fixedly installed on the top of the movable plate 3, a rotating shaft 5 fixedly sleeved at the other end of the output shaft of the drive motor 4, a chamferer 6 fixedly connected at the other end of the rotating shaft 5, a transmission motor 7 fixedly connected to the bottom of the workbench 2, a transmission shaft 8 fixedly sleeved at the other end of the output shaft of the transmission motor 7, a rotating rod 9 fixedly sleeved on the outer surface of the transmission shaft 8, the top of the rotating rod 9 movably connected to the bottom of the workbench 2, a cylindrical block 10 movably connected to the inner surface of the rotating rod 9, and the top of the cylindrical block 10 fixedly connected to the bottom of the movable plate 3.

[0023] When the drive motor 7 is running, the drive shaft 8 will drive the rotating rod 9 to rotate. The rotation of the rotating rod 9 will cause the cylindrical block 10 to move to the left, which in turn will cause the movable plate 3 to drive the drive motor 4 to move to the left as a whole, thereby causing the chamferer 6 to move to the left. This achieves the purpose of chamfering medical plastic tubes of different lengths and improves the applicability of the device.

[0024] The top of the workbench 2 is fixedly connected to a fixing plate 11 located on the left side of the chamferer 6, and the top of the fixing plate 11 is arc-shaped.

[0025] In this design, the fixing plate 11 serves to support the medical tubing.

[0026] The top of the fixed plate 11 is fixedly connected to a U-shaped bracket 12, and a pneumatic cylinder 13 is fixedly installed on the top of the U-shaped bracket 12. The bottom of the pneumatic cylinder 13 passes through the U-shaped bracket 12 and extends to the bottom of the U-shaped bracket 12 and is fixedly connected to a clamp 14. The outer surface of the clamp 14 is movably connected to the inner surface of the U-shaped bracket 12, and the bottom of the clamp 14 is movably connected to the top of the fixed plate 11.

[0027] When the pneumatic cylinder 13 is running, it will drive the clamp 14 to move downward, and in cooperation with the fixing plate 11, it will clamp and fix the medical plastic tube.

[0028] The workbench 2 has a rectangular box 15 fixedly connected to the front and back of the top. A fan 16 is fixedly installed on the outside of the rectangular box 15. An exhaust pipe 17 is fixedly connected to the outside of the fan 16. An air suction pipe 18 is fixedly connected to the inside of the fan 16. The inside of the air suction pipe 18 passes through the rectangular box 15 and extends into the inside of the rectangular box 15. A connecting pipe 20 is fixedly connected to the inside of the rectangular box 15.

[0029] When the two fans 16 are running, they suck up the debris generated by the chamfering of the pipes through the two connecting pipes 20 and the two suction pipes 18. The debris is sucked into the interior of the two rectangular boxes 15 for collection. Then the air is discharged through the two exhaust pipes 17, ensuring the cleanliness of the workbench 2.

[0030] The air intake pipe 18 is internally fixedly connected to a filter screen 19, which is circular in shape.

[0031] The filter screen 19 is designed to block pipe debris, preventing it from entering the fan 16 and causing damage.

[0032] The rectangular box 15 has a collection box 21 that is movably connected inside, and a handle 22 is fixedly connected to the front of the collection box 21.

[0033] This design allows operators to easily move the collection box 21 outward by pulling the handle 22, thus facilitating the centralized processing of debris inside the collection box 21.

[0034] The number of support legs 1 is four, the four support legs 1 are the same size, and the four support legs 1 are symmetrical about the center of the worktable 2.

[0035] The design of four support legs 1 provides better support and stability for the worktable 2.

[0036] Working principle and usage process of this utility model:

[0037] When chamfering the end of a short medical tube, first place the tube above the fixed plate 11, then start the pneumatic cylinder 13, which will drive the clamp 14 to move downwards to clamp and fix the tube. Then start the drive motor 7, which will cause the drive shaft 8 to drive the rotating rod 9 to rotate. The rotation of the rotating rod 9 will drive the cylindrical block 10 to move to the left, which will cause the movable plate 3 to drive the drive motor 4 to move to the left as a whole, so that the chamferer 6 moves to the left and contacts the tube. At this time, start the drive motor 4, which will cause the rotating shaft 5 to drive the chamferer 6 to rotate to chamfer the end of the tube.

[0038] During the pipe chamfering process, debris will remain on the workbench 2, affecting its cleanliness. At this time, starting the two fans 16 will suck up the debris generated during pipe chamfering through the two connecting pipes 20 and the two suction pipes 18. The debris is sucked into the interior of the two rectangular boxes 15, blocked by the two filter screens 19, and then falls into the interior of the two collection boxes 21 for collection. The air is then discharged through the two exhaust pipes 17, ensuring the cleanliness of the workbench 2.
