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 produce 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 in each step. For example, after the steel pipe is cut, it will be first passed through the tape. The steel pipes are bonded together, and then the staff cuts the long steel pipes into shorter strips. Then, alumina is sprayed on both ends of the steel pipes with a handheld nozzle 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, 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. Alumina will generate dust during the spraying process. If the dust is inhaled by the staff for a long time, it may affect the health.

However, when the staff cuts the bonded long steel pipes 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.

DETAILED DESCRIPTION
[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0027] Example:
[0028] See also Figure 1 - Figure 6As shown, a production device for syringe needles includes a base 1, a driving mechanism 2 is arranged inside the base 1, the driving mechanism 2 includes a stepping motor 201, and the stepping motor 201 is arranged inside the base 1 through a motor seat, the stepping motor 201 is arranged 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 transmission, and 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 arranged on the right side above the base 1, and 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 opened at the upper right end of the base 1. The lower right end of the spray pipe 303 passes through the through hole 6 and extends to the inside of the base 1, and the diameter of the through hole 6 is larger than the outer diameter of the spray pipe 303. A bellows 4 is arranged at the lower right end of the spray pipe 303. A liquid inlet pipe 5 is arranged at the lower end of the bellows 4, and 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, so that when the liquid pump is working, the alumina can be pumped to 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 movable plate 301 is provided with a first slide groove 304 and a second slide groove 307, and a slider 305 and a slider 308 are slidably installed in the first slide groove 304 and the second slide groove 307, respectively. The arrangement of the first slide groove 304 and the second slide groove 307 provides a movable space for the slider 305 and the slider 308, respectively, so that the slider 305 and the slider 308 can smoothly move horizontally in the first slide groove 304 and the second slide groove 307. The front end of the movable plate 301 and the inner part of the slider 308 are The first and second parts of the movable plate 301 are provided with a thread groove 311, a fixing plate 306 is provided on the right side of the slider 1 305, and the lower end of the fixing 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 installed 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, and the left end of the rotating gear 204 is meshed and connected 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 provide limited support for 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, so as to avoid the displacement of the movable plate 301 during the movement process and affect 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 slider 2 308 are aligned, the fixing bolts are screwed in to fix the movable plate 301 to the slider 2 308 through the fixing bolts. At this time, the rotating rod 309 is rotated counterclockwise by 90 degrees, 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] A clamping mechanism 7 is provided on the left side of the movable plate 301, and the clamping mechanism 7 includes a rotating shaft 2 702, and the rotating shaft 2 702 is rotatably installed inside the upper end of the base 1, and a lower clamping plate 703 is provided on 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 installed on the circumferential surface of the fixing rod 1 704, and 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 rod 1 706 is threadedly connected to the right side of the upper clamping plate 705, and the lower end of the screw rod 1 706 is rotatably installed inside the lower clamping plate 703. Because of the limitation of the fixing rod 1 704, when the staff rotates the screw rod 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, and 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 aluminum oxide. The lower end of the rotating shaft 2 702 is provided with a driven gear 701, and the left end of the rotating gear 1 203 is meshed and connected 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, so that 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 toothed 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, and 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 and avoid the movement of the steel pipe during work and affect the work quality.
[0035] A cutting mechanism 8 is arranged below the lower clamping plate 703, and the cutting mechanism 8 includes a lower pressing block 801, a fixing rod 803 and a fixing plate 810. The lower pressing block 801 is arranged at the left end of the lower surface of the driven gear 701, the fixing rod 803 is arranged inside the base 1 and is located on the left side of the driven gear 701, the fixing plate 810 is arranged on the upper surface of the base 1 and is located below the lower clamping plate 703, and a lifting plate 802 is sleeved on the circumferential surface of the fixing rod 803, and the lifting plate 802 is fixedly connected to an arc plate 809 through a connecting plate 808. The internal thread of the lifting plate 802 is connected to a screw rod 806, and the screw rod 806 is provided with a plurality of groups, and the upper ends of the plurality of groups of screw rods 806 all penetrate the upper part of the base 1 and the fixing plate 810 and are connected to 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 lower clamping plate 703, so as to cut the steel pipe into different lengths, thereby improving the flexibility during work. The circumferential surface of the second fixed 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 fixed 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 in 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 respectively located in front of and behind the upper clamping plate 705 and the lower clamping plate 703, 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 pressing block 801 are against each other, and the rear end of the left side of the arc plate 809 and the front end of the lower pressing block 801 are both arc-shaped. The arc-shaped design of the rear end of the left side of the arc plate 809 and the front side of the lower pressing block 801 enables the lower pressing block 801 to squeeze the arc plate 809 downward when the driven gear 701 drives the lower pressing block 801 to rotate counterclockwise, and then the arc plate 809 drives 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 second fixed plate 810 to prevent the cutting blade 807 from affecting the rotation of the lower clamping plate 703. A receiving groove 10 is opened at the front end of the middle part of the lower clamping plate 703. The second fixed plate 810 is arranged directly below the receiving groove 10. The upper end of part of the cutting blade 807 passes through the second fixed plate 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 used, the screw rod 706 is first rotated to make the upper clamping plate 705 move vertically upward, and then the steel pipe bonded by the tape into a long strip 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, and then the screw rod 706 is rotated in the opposite direction to make the upper clamping plate 705 move downward and cooperate with the lower clamping plate 703 to clamp and fix the steel pipe, and then the sealing door 9 is opened, and the screw rod 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, and then the right end of the liquid inlet pipe 5 is connected to the liquid pump;
[0039] Then, the stepper motor 201 is started, and the stepper motor 201 drives the rotating shaft 1 202, the rotating gear 1 203 and the rotating gear 2 204 to rotate clockwise. The rotating gear 1 203 drives the driven gear 701 and the 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, and a whole long steel pipe can be cut into multiple sections. After the automatic cutting work is completed, the gear 204 is rotated to drive the toothed plate 310 to move horizontally backward, and then the movable plate 301, the mounting block 302 and the spraying pipe 303 are driven 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 of 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, the stepper motor 201 is started 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 90 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, and 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 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 spraying pipe 303 sprays aluminum oxide on the other end of the steel pipe to clean both ends of the steel pipe, and then the screw 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.
