Description

Technical Field

[0001] This utility model belongs to the field of medical device manufacturing, specifically relating to a fixing device for processing disposable syringe needles. Background Technology

[0002] In the field of medical device manufacturing, the processing of disposable syringe needles plays a crucial role. As an indispensable component of syringes, the quality and processing precision of the needle directly affect patient safety and treatment outcomes. Therefore, selecting and using appropriate fixing devices is particularly important in the needle processing flow. Traditional needle processing fixing devices, such as the "Fixing Device for Syringe Needle Processing" disclosed in utility model patent CN217860540U, mainly rely on mechanical clamping to achieve stable fixation of the needle, thus facilitating subsequent sawing, grinding, and other fine processing steps. This device, through its ingenious structural design, ensures the needle's stability during processing. Stability and alignment accuracy during the manufacturing process are crucial for improving processing efficiency and product quality. However, although the fixing device disclosed in patent CN217860540U performs well in clamping, fixing, and aligning needles, it has significant shortcomings in handling the dust generated during processing. During needle processing, especially in the sawing and grinding stages, a large amount of tiny dust is generated. This dust is not only small in size but also in large quantity. If it is not collected and treated in time, it can easily escape into the air and pollute the working environment. More seriously, this dust may also adhere to the surface and inner wall of the needle, causing secondary pollution and seriously affecting the quality and safety of the needle. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a fixing device for processing disposable syringe needles, thereby solving the problem of not being able to collect the powder generated during syringe needle processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a fixing device for processing disposable syringe needles, comprising a device body, a door panel, a chip suction cover, a rotating seat, and a heat dissipation window. The device body has a chip collection chamber and a cavity, with a chip collection box for collecting powder chips placed in the chip collection chamber. A fan is installed in the cavity, and a filter plate is installed at the connection between the cavity and the chip collection chamber. The chip suction cover is connected to the chip collection chamber via a chip suction pipe. The rotating seat is located above the device body and is rotatably connected to it. One end of the rotating seat is connected to the output end of a motor installed inside the device body via a coupling to drive the rotating seat to rotate, thereby adjusting the angle of the rotating seat. The chip suction cover is located on the device body below the front end of the rotating seat. The rotating seat has a needle groove for accommodating needles. A support column is installed on the rotating seat, and a lifting groove is provided on the support column. An electric lifting rod is installed in the support column, and the output end of the electric lifting rod is connected to a pressure plate.

[0005] The beneficial effects of this utility model are as follows: by activating the dust suction function and turning on the fan, the dust generated during the processing of disposable syringe needles can be sucked up and collected through the dust suction pipe and dust suction hood, preventing it from escaping into the air and causing pollution to the working environment, as well as from adhering to the surface and inner wall of the needle and causing secondary pollution.

[0006] To facilitate opening and closing the chip collection chamber:

[0007] As a further improvement to the above technical solution: the door panel is located at the opening at the front end of the chip collection cavity, and the bottom end of the door panel is hinged to the device body via a hinge.

[0008] The beneficial effects of this improvement are as follows: the door panel facilitates the opening and closing of the chip collection chamber. When the chip collection chamber is open, it facilitates the removal or placement of the chip collection box. When the chip collection chamber is closed, it prevents the chip collection box from falling out and prevents dust from overflowing from the chip collection chamber after the chip suction function is activated.

[0009] To facilitate easier movement of the chip collection box:

[0010] As a further improvement to the above technical solution: rollers are provided at the four corners of the bottom of the chip collection box.

[0011] The beneficial effects of this improvement are: by setting rollers at the four corners of the bottom of the chip collection box, the convenience of removing, placing and relocating the chip collection box can be improved.

[0012] To facilitate ventilation and heat dissipation, and to prevent the filtering of dust:

[0013] As a further improvement to the above technical solution: the heat dissipation window is located at the air outlet of the cavity, while the filter plate is located at the air inlet of the cavity.

[0014] The beneficial effects of this improvement are: the installation of heat dissipation windows facilitates ventilation and heat dissipation of the fan, and the installation of filter plates can block and filter dust that approaches the cavity.

[0015] To facilitate the placement of the needle:

[0016] As a further improvement to the above technical solution: the number of needle grooves is several, and the several needle grooves are arranged at equal intervals on the top of the rotating seat to accommodate disposable syringe needles.

[0017] The beneficial effect of this improvement is that the needle groove can accommodate disposable syringe needles.

[0018] To facilitate the lifting and lowering adjustment of the pressure plate:

[0019] As a further improvement to the above technical solution: support columns are vertically arranged in the middle of both sides of the rotating seat, and lifting grooves are vertically opened on the inner side of both support columns. The two sides of the pressure plate are respectively located in the lifting grooves on both sides and are movably connected to the lifting grooves.

[0020] The beneficial effects of this improvement are as follows: after the electric lifting rod is started, the pressure plate can be adjusted to rise and fall. When the pressure plate moves downward, it can squeeze and fix the needles contained in the needle groove. Conversely, when it moves upward, it can facilitate the removal and placement of the needles.

[0021] To improve the pressure plate's ability to compress and hold the needle in place:

[0022] As a further improvement to the above technical solution: an anti-slip rubber pad is provided at the bottom of the pressure plate.

[0023] The beneficial effects of this improvement are: by setting up an anti-slip rubber pad at the bottom of the pressure plate, the pressure plate can improve the squeezing and fixing effect on the needle, ensuring the stability of the fixation.

[0024] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

A chip collection box 8 for collecting powder chips is placed in the chip collection chamber 6. A fan 10 is installed in the cavity 7, and a filter plate 11 is installed at the connection between the cavity 7 and the chip collection chamber 6. The chip suction hood 3 is connected to the chip collection chamber 6 via a chip suction pipe 12. The rotating seat 4 is located above the device body 1 and is rotatably connected to it. One end of the rotating seat 4 is connected to the output end of a motor 13 installed inside the device body 1 via a coupling, used to drive the rotating seat 4 to rotate, thereby achieving angle adjustment of the rotating seat 4. The chip suction hood 3... Located below the front end of the rotating seat 4, the device body 1 has a needle groove 14 for accommodating needles. A support column 15 is provided on the rotating seat 4, and a lifting groove 16 is provided on the support column 15. An electric lifting rod 17 is installed in the support column 15, and the output end of the electric lifting rod 17 is connected to the pressure plate 18. By activating the dust collection function and turning on the fan 10, the dust generated during the processing of disposable syringe needles can be collected through the dust collection pipe 12 and the dust collection cover 3, preventing it from escaping into the air and polluting the working environment, and preventing it from adhering to the surface and inner wall of the needle and causing secondary pollution. The door panel 2 is located at the opening of the dust collection cavity 6, and the bottom end of the door panel 2 is hinged to the device body 1 via a hinge. The design of section 2 facilitates the opening and closing of the chip collection chamber 6. When the chip collection chamber 6 is open, it facilitates the removal or placement of the chip collection box 8. When the chip collection chamber 6 is closed, it prevents the chip collection box 8 from falling out and prevents dust from overflowing from the chip collection chamber 6 after the chip suction function is activated. Rollers 9 are provided at the four corners of the bottom of the chip collection box 8. The rollers 9 at the four corners of the bottom of the chip collection box 8 facilitate the removal, placement, and displacement of the chip collection box 8. The heat dissipation window 5 is located at the air outlet of the cavity 7, while the filter plate 11 is located at the air inlet of the cavity 7. The heat dissipation window 5 facilitates the ventilation and heat dissipation of the fan 10. The filter plate 11 can block and filter the dust approaching the cavity 7. The number of needle grooves 14 is several, and several needles The slots 14 are evenly spaced at the top of the rotating base 4 to accommodate disposable syringe needles. The slots 14 allow for the storage of disposable syringe needles. Support columns 15 are vertically arranged at the center of both sides of the rotating base 4, and lifting slots 16 are vertically formed on the inner side of each support column 15. The pressure plate 18 is located in and movably connected to the lifting slots 16 on both sides. After being activated by the electric lifting rod 17, the pressure plate 18 can be adjusted in height. When the pressure plate 18 moves downward, it can compress and fix the needles stored in the slots 14; conversely, moving upward facilitates the removal and placement of the needles. An anti-slip pad 19 is provided at the bottom of the pressure plate 18.This improves the squeezing and fixing effect of the pressure plate 18 on the needle, ensuring stability.

[0034] The working principle of this utility model is as follows: When the motor 13 drives the rotating seat 4 to tilt backward, the needles placed in each needle groove 14 can automatically slide backward to align under the tilt. After alignment, the electric lifting rod 17 starts to drive the pressure plate 18 to move downward, which can squeeze and fix the needles in the needle groove 14. After the needles are fixed, the motor 13 drives the rotating seat 4 to tilt forward, which facilitates sawing or grinding of the front end of the needle. During the processing of the front end of the needle, the chip suction function is activated. The fan 10 is turned on, which can suck up and collect the powder generated during the processing of disposable syringe needles through the chip suction pipe 12 and the chip suction cover 3. The powder collected in the chip collection chamber 6 can fall into the chip collection box 8 for centralized collection.
