Description

Technical Field

[0001] This utility model relates to the technical field of needle tip sharpening equipment, and in particular to needle tip sharpening equipment for the production of disposable injection needles. Background Technology

[0002] The needle tip sharpening equipment for disposable injection needles is an automated specialized machine designed for processing the tips of disposable injection needles. Its core function is to use grinding and cutting processes to process one end of the metal needle tube into a sharp, smooth tip that meets medical standards.

[0003] However, the traditional equipment feeding process relies heavily on manual feeding, which not only has a low degree of automation but also makes it difficult to adapt to the needs of mass production, directly causing a bottleneck in production efficiency. On the other hand, the needle fixing device of the equipment often adopts a flat pressure plate design, which is affected by the accuracy of clamping force control. Problems are prone to occur during processing. Either the needle will loosen due to insufficient clamping force, or the needle will be squeezed and deformed due to excessive clamping force. Both of these situations will directly affect the final processing accuracy of the needle. Utility Model Content

[0004] The purpose of this invention is to ensure that the needle tube is in a uniform and stable position during processing, avoiding processing errors caused by needle tube displacement or loosening. It provides a needle tip sharpening device for disposable injection needle production, which solves the problems of traditional equipment lacking automatic feeding and effective fixing and positioning devices.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-5 This utility model embodiment includes a needle tip sharpening device for producing disposable injection needles, comprising a base 1, a lower pressure plate 2 fixedly connected above the base 1, an arc-shaped slide rail 4 fixedly connected above one side of the base 1, a support rod 5 connected inside the arc-shaped slide rail 4, an upper pressure plate 6 rotatably connected to the middle of the support rod 5, a support shaft 7 fixedly connected above the base 1, a support plate 8 fixedly connected above the support shaft 7, a first piston rod 10 slidably connected to the middle of the support plate 8, a support seat 25 fixedly connected below the first piston rod 10, a guide shaft 23 fixedly connected inside the support seat 25, a pusher 21 slidably connected to the lower part of the guide shaft 23, and a hopper 20 fixedly connected to one side of the pusher 21.

[0019] Specifically, the support rod 5 drives the upper pressure plate 6 to slide on the arc-shaped slide 4 until the upper pressure plate 6 and the lower pressure plate 2 are pressed together to achieve the pressing effect. The contact surfaces of the upper pressure plate 6 and the lower pressure plate 2 are provided with multiple semi-circular grooves. The hopper 20 can release raw materials in an orderly manner one by one. The hopper 20 and the pusher 21 move axially along the guide shaft 23 to evenly arrange the raw materials in the semi-circular grooves of the lower pressure plate 2.

[0020] Multiple needle tubes 3 are installed above the lower pressure plate 2.

[0021] A first motor 11 is fixedly connected to one side of the base 1, and a worm gear 12 is slidably connected to one side of the first motor 11.

[0022] Specifically, the first motor 11 drives the worm gear 12 to rotate.

[0023] A rotating shaft 14 is rotatably connected to the inner wall of one side of the base 1. A worm gear 13 is rotatably connected to the middle of the rotating shaft 14. The worm gear 13 is meshed with the worm 12. A crank rod 15 is rotatably connected to the other end of the rotating shaft 14. The other end of the crank rod 15 is fixedly connected to the support rod 5.

[0024] Specifically, the worm gear 12 drives the worm wheel 13 to rotate. Under the transmission of the rotating shaft 14, the crank rod 15 rotates around the rotating shaft 14, causing the support rod 5 to slide in the arc-shaped slide 4. The upper pressure plate 6 moves under the drive of the support rod 5 until it fits against the lower pressure plate 2.

[0025] A second cylinder 16 is fixedly connected to one end of the base 1. A second piston rod 17 is slidably connected to one end of the second cylinder 16. An alignment plate 18 is fixedly connected to the other end of the second piston rod 17. A T-shaped slider 19 is fixedly connected below the alignment plate 18. The T-shaped slider 19 can slide on the base plate of the base 1.

[0026] Specifically, the second cylinder 16 pushes the second piston rod 17 to slide. Under the action of the second piston rod 17, the alignment plate 18 slides along the bottom plate with the help of the T-shaped slider 19 at the bottom, pushing the needle tube 3 on the lower pressure plate 2 until it is completely aligned with one side of the lower pressure plate 2.

[0027] A first cylinder 9 is fixedly connected above the support plate 8, and a first piston rod 10 is installed inside the first cylinder 9.

[0028] Specifically, the first cylinder 9 pushes the first piston rod 10 to move, the first piston rod 10 drives the lower support seat 25 to move, and the hopper 20 and the leveler 21 move accordingly to facilitate material discharge and leveling.

[0029] One end of the support base 25 is fixedly connected to a second motor 22, and the other end of the second motor 22 is rotatably connected to a screw 24.

[0030] Specifically, the second motor 22 drives the screw 24 to rotate, and with the help of the internal thread structure of the pusher 21, the pusher 21 can move along the axial direction of the screw 24.

[0031] A third motor 28 is fixedly connected to one side of the hopper 20, and a drive rod 27 is rotatably connected to one side of the third motor 28. A roller 26 is fixedly connected to the other end of the drive rod 27.

[0032] Specifically, the third motor 28 drives the drive rod 27 to rotate, and the roller 26 rotates accordingly. One side of the roller 26 has a slot that can only accommodate a single needle tube 3. When it rotates to the bottom of the hopper 20, the needle tube 3 falls into the lower pressure plate 2 along with the slot.

[0033] Working principle: With all structures in their initial state, insert the needle 3 into the hopper 20. Activate the first cylinder 9 above the support plate 8. The first cylinder 9 pushes the internal first piston rod 10 to move, which in turn moves the lower support seat 25. The hopper 20 and the leveler 21 move downwards synchronously. When it reaches the bottom, the distance between the leveler 21 and the lower pressure plate 2 is slightly greater than the radius of the needle 3 but less than its diameter. Activate the third motor 28 on one side of the hopper 20. The third motor 28 drives the drive... The rod 27 rotates, which in turn drives the roller 26 to rotate. When the groove on the roller 26, which can only accommodate a single needle tube 3, rotates to the bottom of the hopper 20, the needle tubes 3 fall one by one into the semi-circular groove of the lower pressure plate 2 above the base 1. At the same time, the second motor 22 is started, which drives the screw 24 to rotate. With the help of the internal thread structure of the pusher 21, the pusher 21 and the hopper 20 on one side move axially along the guide shaft 23 inside the support base 25. Under the action of the pusher 21, the needle tubes 3 on the lower pressure plate 2 are evenly spread. After the needle 3 is placed, the first cylinder 9 is driven in reverse to fully retract the first piston rod 10. This activates the second cylinder 16 on one side of the base 1. The second cylinder 16 pushes the second piston rod 17 to slide, which in turn moves the alignment plate 18. The alignment plate 18 slides on the base plate 1 using the T-shaped slider 19 below, pushing the needle 3 on the lower pressure plate 2 until it is fully aligned with one side of the lower pressure plate 2. The second cylinder 16 is then driven in reverse until the second piston rod 17 is fully retracted. Finally, the cylinder 16 on one side of the base 1 is activated. The first motor 11 drives the worm gear 12 to rotate. The worm gear 12 meshes with the worm wheel 13 in the middle of the rotating shaft 14 on the inner wall of one side of the base 1, so that the rotating shaft 14 drives the crank rod 15 at the other end to rotate around the rotating shaft 14. The crank rod 15 then drives the support rod 5 to slide inside the arc-shaped slide 4. The upper pressure plate 6, which is rolled in the middle of the support rod 5, moves with the support rod 5 until the upper pressure plate 6 presses against the lower pressure plate 2, thus completing the pressing of multiple needle tubes 3 above the lower pressure plate 2, and preparing for the subsequent needle tip sharpening process.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
