Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment production, and in particular relates to production equipment for syringe needles. Background Art

[0002] The injection needle is a very delicate medical device. The conventional production steps of the injection needle are to cut the seamless steel pipe with the existing aperture, grind the cut workpiece to form the needle tip bevel, and then assemble the grinded needle workpiece with the pin workpiece. In the existing manufacturers' production, the above steps of the injection needle are often processed by split cutting equipment, grinding equipment and assembly equipment. The production process is often semi-automatic, and manual feeding or transfer is required at each step. For example, after the steel pipe is cut, it will be passed through a tape. The steel pipes are bonded together, and then the staff cuts the long steel pipes into shorter strips. Then, they use a handheld nozzle to spray aluminum oxide on both ends of the steel pipes to clean the surface of the steel pipes to facilitate the subsequent grinding work of the grinding equipment. However, when the staff cuts the bonded long steel pipes into shorter strips, they need to manually measure each time to avoid cutting different lengths, which is time-consuming and labor-intensive, and the overall work efficiency is low. In addition, aluminum oxide will generate dust during the spraying process. If the dust is inhaled by the staff for a long time, it may affect their health.

[0003] Therefore we propose a production equipment for syringe needles to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that after the steel pipes are cut, they are first glued together with tape, and then the staff cuts the long steel pipes into shorter strips, and then sprays aluminum oxide on both ends of the steel pipe with a handheld nozzle to clean the surface of the steel pipe to facilitate the subsequent polishing work of the polishing equipment. However, when the staff cuts the long steel pipes glued together into shorter strips, manual measurement is required each time to avoid cutting different lengths, which is time-consuming and labor-intensive, and the overall work efficiency is low. In addition, aluminum oxide will generate dust during the spraying process. If the dust is inhaled by the staff for a long time, it may affect the health of the body. Therefore, a production equipment for syringe needles is proposed.

[0026] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example:

[0028] See also Figure 1 - Figure 6As shown, a syringe needle production device includes a base 1, a driving mechanism 2 is disposed inside the base 1, and the driving mechanism 2 includes a stepping motor 201. The stepping motor 201 is disposed inside the base 1 through a motor seat. The stepping motor 201 is disposed inside the right side of the base 1. The power output end of the stepping motor 201 is connected to a rotating shaft 1 202 through a coupling. The circumferential surface of the rotating shaft 1 202 is sequentially provided with a rotating gear 1 203 and a rotating gear 2 204 from bottom to top.

[0029] A moving mechanism 3 is provided on the right side above the base 1. The moving mechanism 3 includes a moving plate 301. A spray pipe 303 is fixedly installed on the left side above the moving plate 301 through a mounting block 302. A through hole 6 is provided at the upper end of the right side of the base 1. The lower end of the right side of the spray pipe 303 passes through the through hole 6 and extends to the interior of the base 1. The diameter of the through hole 6 is larger than the outer diameter of the spray pipe 303. A bellows 4 is provided at the lower end of the right side of the spray pipe 303. A liquid inlet pipe 5 is provided at the lower end of the bellows 4. The right end of the liquid inlet pipe 5 passes through the right side of the base 1 and extends to the outside. The right end of the liquid inlet pipe 5 is connected to an external liquid pump. When the liquid pump is working, the alumina can be pumped into the spray pipe 303 through the liquid pump, and then smoothly sprayed on the surface of the steel pipe.

[0030] It should be noted that when the movable plate 301 drives the spray pipe 303 to move horizontally back and forth, the spray pipe 303 will pull the bellows 4, causing the bellows 4 to stretch or fold, thereby enabling the movable plate 301 to smoothly drive the spray pipe 303 to move horizontally back and forth. The diameter of the cut-through hole 6 is larger than the diameter of the spray pipe 303, so that when the spray pipe 303 is pulled, there will be no large friction between its surface and the base 1, thereby reducing the wear of the spray pipe 303 and increasing the service life of the spray pipe 303.

[0031] The interior of the movable plate 301 is provided with a chute 1 304 and a chute 2 307, and the interior of the chute 1 304 and the chute 2 307 is slidably installed with a slider 1 305 and a slider 2 308. The arrangement of the chute 1 304 and the chute 2 307 provides a movable space for the slider 1 305 and the slider 2 308, respectively, so that the slider 1 305 and the slider 2 308 can smoothly move horizontally inside the chute 1 304 and the chute 2 307. The front end interior of the movable plate 301 and the interior of the slider 2 308 A threaded groove 311 is provided on each of the parts. A fixed plate 306 is provided on the right side of the slider 1 305, and the lower end of the fixed plate 306 is provided on the upper surface of the base 1. A rotating rod 309 is provided on the lower end of the slider 2 308, and the lower end of the rotating rod 309 is rotatably mounted inside the upper end of the base 1. A tooth plate 310 is provided on the left end of the lower surface of the movable plate 301. The left end of the rotating gear 204 is meshed with the right side of the tooth plate 310, and the initial position of the rotating gear 204 is located in the middle of the tooth plate 310.

[0032] It should be noted that the setting of the slider 1 305, the fixed plate 1 306, the slider 2 308 and the rotating rod 309 can limit the support of the movable plate 301, so that the movable plate 301 can be stably set at a position higher than the steel pipe, which is convenient for spraying aluminum oxide, and can guide the movable plate 301 so that when the rotating gear 204 drives the tooth plate 310 to move, the tooth plate 310 drives the movable plate 301 to move horizontally back and forth stably, avoiding the displacement of the movable plate 301 during the movement process and affecting the use effect. The setting of the threaded groove 311 inside the front end of the movable plate 301 and the slider 2 308 is that when the device is not in use, the stepper motor 201 is first driven to rotate the movable plate 301. The movable rotating gear 204 rotates, thereby driving the tooth plate 310 to move backward, so that the tooth plate 310 is disengaged from the rotating gear 204. At this time, the movable plate 301 is manually pushed backward, and the slider 1 305 is disengaged from the inside of the movable plate 301 through the front end of the slide groove 1 304. Then, when the threaded groove 311 inside the movable plate 301 and the inside of the slider 2 308 are aligned, the fixing bolt is screwed in so that the movable plate 301 is fixedly connected to the slider 2 308 through the fixing bolt. At this time, the rotating rod 309 is rotated ninety degrees counterclockwise, so that the movable plate 301 is located on the rear side of the upper clamping plate 705 and is in a parallel state, which reduces the space occupied by the equipment and facilitates the storage of the equipment.

[0033] The left side of the movable plate 301 is provided with a clamping mechanism 7, which includes a rotating shaft 2 702, and the rotating shaft 2 702 is rotatably mounted inside the upper end of the base 1, and a lower clamping plate 703 is provided at the upper end of the rotating shaft 2 702, and a fixing rod 1 704 is provided at the right end of the upper surface of the lower clamping plate 703, and an upper clamping plate 705 is slidably mounted on the circumferential surface of the fixing rod 1 704. The setting of the fixing rod 1 704 can limit the upper clamping plate 705 so that the upper clamping plate 705 can move vertically on the fixing rod 1 704, and a screw 1 706 is connected to the inner thread of the right side of the upper clamping plate 705, and the lower end of the screw 1 706 is rotatably mounted inside the lower clamping plate 703. Because of the limitation of the fixing rod 1 704, when the staff rotates the screw 1 706, it will drive The upper clamping plate 705 moves in the vertical direction. When the upper clamping plate 705 moves upward, it is convenient to put the long steel pipe after bonding between the upper clamping plate 705 and the lower clamping plate 703. Then, the screw rod 1 706 is rotated in the opposite direction so that the upper clamping plate 705 and the lower clamping plate 703 clamp and fix the steel pipe, which is convenient for the subsequent spraying of alumina. The lower end of the rotating shaft 2 702 is provided with a driven gear 701. The left end of the rotating gear 1 203 is meshed with the right end of the driven gear 701. The diameter of the driven gear 701 is larger than the diameter of the rotating gear 1 203. When the rotating gear 1 203 drives the driven gear 701 and the rotating shaft 2 702 to rotate ninety degrees, the rotating gear 2 204 can drive the tooth plate 310 and the moving plate 301 to move backward by half the length of the moving plate 301.

[0034] It should be noted that arc grooves are provided on the upper surface of the lower clamping plate 703 and the lower surface of the upper clamping plate 705. The size of the arc grooves matches the steel pipe, so that the upper clamping plate 705 and the lower clamping plate 703 can better clamp the steel pipe, avoiding the movement of the steel pipe during work and affecting the work quality.

[0035] A cutting mechanism 8 is provided below the lower clamping plate 703. The cutting mechanism 8 includes a lower pressing block 801, a second fixing rod 803 and a second fixing plate 810. The lower pressing block 801 is provided at the left end of the lower surface of the driven gear 701. The second fixing rod 803 is provided inside the base 1 and is located on the left side of the driven gear 701. The second fixing plate 810 is provided on the upper surface of the base 1 and is located below the lower clamping plate 703. The circumferential surface of the second fixing rod 803 is provided with a lifting plate 802. The lifting plate 802 is fixedly connected to the arc plate 809 through the connecting plate 808. The internal thread of the lifting plate 802 is connected to the second screw 806, and the second screw 806 is provided with several groups. The upper ends of the several groups of second screws 806 all pass through the top of the base 1 and the second fixing plate 810 and are connected with cutting blades 807. The arrangement of the second screw rod 806 and the cutting blade 807 can move the tip of the cutting blade 807 at different positions into the interior of the lower clamping plate 703, thereby cutting the steel pipe into different lengths, which improves the flexibility during work. The circumferential surface of the second fixing rod 803 is provided with a fixed stopper 805, and the lower surface of the fixed stopper 805 abuts against the upper surface of the lifting plate 802. The circumferential surface of the second fixing rod 803 is sleeved with a spring 804, the upper end of the spring 804 is connected to the lower surface of the lifting plate 802, and the lower end of the spring 804 is connected to the inner bottom wall of the base 1. The arrangement of the spring 804 can make the lifting plate 802 be in a position abutting against the fixed stopper 805 when not subject to external force, thereby making the tip of the previously adjusted cutting blade 807 always inside the lower clamping plate 703;

[0036] It should be noted that, because the tape for bonding the steel pipe is located near the front end of the steel pipe, that is, when the steel pipe is placed between the upper clamping plate 705 and the lower clamping plate 703, its front and rear ends are located in front of and behind the upper clamping plate 705 and the lower clamping plate 703 respectively, and the position of the tape is inside the front end of the lower clamping plate 703, that is, in front of the cutting blade 807. At this time, when the driving mechanism 2 drives the upper clamping plate 705 and the lower clamping plate 703 to rotate clockwise, the cutting blade 807 contacts the tape and can cut the tape, so that the long steel pipe is cut into multiple shorter groups.

[0037] The arc plate 809 is arranged below the driven gear 701, and the rear end of the left side of the arc plate 809 and the front end of the lower pressure block 801 are both in an arc shape. The design of the rear end of the left side of the arc plate 809 and the front arc of the lower pressure block 801 makes it possible for the driven gear 701 to drive the lower pressure block 801 to rotate counterclockwise, and the lower pressure block 801 can squeeze the arc plate 809 downward, thereby causing the arc plate 809 to drive the lifting plate 802 to move downward through the connecting plate 808, and then the lifting plate 802 drives the cutting blade 807 downward. Move it into the interior of the fixed plate 2 810 to prevent the cutting blade 807 from affecting the rotation of the lower clamping plate 703. A receiving groove 10 is provided at the front end of the middle part of the lower clamping plate 703. The fixed plate 2 810 is arranged directly below the receiving groove 10. The upper end of part of the cutting blade 807 passes through the fixed plate 2 810 and extends to the interior of the receiving groove 10. The setting of the receiving groove 10 allows the tip of the cutting blade 807 to smoothly enter the interior of the lower clamping plate 703, thereby facilitating the cutting work. The front side of the base 1 is hinged with a sealing door 9 through a hinge shaft, and the sealing door 9 is arranged directly in front of the lifting plate 802.

[0038] When the present invention is in use, first, the screw rod 1 706 is rotated to move the upper clamping plate 705 vertically upward, and then the steel pipe bonded to the long strip by the tape is laid between the upper clamping plate 705 and the lower clamping plate 703, so that the front and rear ends of the steel pipe are exposed. Then, the screw rod 1 706 is rotated in the opposite direction, so that the upper clamping plate 705 moves downward and cooperates with the lower clamping plate 703 to clamp and fix the steel pipe. Then, the sealing door 9 is opened, and the screw rod 2 806 at the corresponding position is rotated to drive the cutting blade 807 above it to move upward, so that the tip of the cutting blade 807 moves into the interior of the lower clamping plate 703. Then, the right end of the liquid inlet pipe 5 is connected to the liquid pump.

[0039] Then start the stepper motor 201, which drives the rotating shaft 1 202, rotating gear 1 203 and rotating gear 2 204 to rotate clockwise. The rotating gear 1 203 drives the driven gear 701 and rotating shaft 2 702 to rotate, and then drives the upper clamping plate 705, the lower clamping plate 703 and the steel pipe to rotate clockwise. When the clamping plate rotates clockwise, the tape on the steel pipe contacts the cutting blade 807, which can cut a whole long steel pipe into multiple sections. After the automatic cutting is completed, the gear 2 204 is rotated to drive the toothed plate 310 to move horizontally backward, which in turn drives the movable plate 301, the mounting block 302 and the spraying pipe 303 to move horizontally backward. After the upper clamping plate 705 and the lower clamping plate 703 rotate 90 degrees and stop, the movable plate 301 moves horizontally backward to half its length and then stops. At this time, the liquid pump is started, so that the spraying pipe 303 sprays aluminum oxide on the surface of one end of the steel pipe. After the spraying is completed, the liquid pump stops working.

[0040] Then start the stepper motor 201 again, and the stepper motor 201 drives the rotating shaft 1 202, the rotating gear 1 203 and the rotating gear 2 204 to rotate counterclockwise again. After the rotating gear 1 203 and the rotating gear 2 204 rotate counterclockwise by ninety degrees, the upper clamping plate 705, the lower clamping plate 703 and the movable plate 301 all move to the initial position, and then continue to rotate counterclockwise. The upper clamping plate 705 and the lower clamping plate 703 drive the steel pipe to rotate to the front. At this time, when the driven gear 701 drives the lower pressing block 801 to rotate counterclockwise, the lower pressing block 801 will contact the arc plate 809 and press it down, so that the arc plate 809 drives the lifting plate 802 to move downward through the connecting plate 808, and the lifting plate 802 drives the screw 2 806 and The cutting blade 807 moves downward, so that the cutting blade 807 located inside the lower clamping plate 703 moves into the fixed plate 2 810, and then the cutting blade 807 does not affect the rotation of the lower clamping plate 703. Then, when the upper clamping plate 705 and the lower clamping plate 703 are located in front of the rotating shaft 202 and are in a longitudinal horizontal state, the movable plate 301 also moves as a whole to the front of the rotating shaft 202. At this time, the liquid pump is started again, so that the spray pipe 303 sprays aluminum oxide on the other end of the steel pipe to clean both ends of the steel pipe. Then, the screw 1 706 is rotated to move the upper clamping plate 705 upward. At this time, the cleaned steel pipe can be taken out from the upper clamping plate 705 and the lower clamping plate 703, which is convenient for the subsequent grinding of the steel pipe.
