Description

Technical Field

[0001] The utility model relates to the field of plastic syringe filling machines, in particular to a plastic syringe filling and plugging machine. Background Art

[0002] In the medical field, people often use syringes as one of the important means of medical treatment. A syringe usually includes a needle tube for storing injection liquid, a piston rod for pressing the injection liquid, a needle for injecting liquid, and a needle handle for people to apply force during injection. The needle handle is usually a circle of flange with a larger diameter. With the widespread use of syringes, safe and simple pre-filled syringes have also emerged. Pre-filled syringes have both the functions of storing drugs and injecting, and use materials with high compatibility and stability. They are not only safe and reliable, but also save labor and costs. The emergence of syringe filling and stoppering machines has helped people to fill syringes effectively and quickly. Usually, the working steps of this type of syringe filling and stoppering machine are divided into feeding, adding liquid, and stoppering.

[0003] After the existing stoppering machine is used to fill the plastic syringe with liquid and stopper it, the plastic syringe is guided and transported outward by a slide rail, and finally the plastic syringe falls freely from the end of the slide rail into the collection box. This automatic unloading method will cause a large number of plastic syringes to fall into the collection box along the slide rail. At the moment of falling, the plastic syringes will collide with each other, which may easily cause the stopper of the plastic syringe or the plastic syringe itself to deform, thereby affecting the subsequent normal use. Therefore, it is necessary to design a plastic syringe filling and stoppering machine. Utility Model Content

[0006] Furthermore, the upper end surfaces of the first slide rail and the second slide rail are both provided with mounting grooves, and a plurality of rollers are rotatably connected inside the mounting grooves.

[0007] Furthermore, the baffle is L-shaped and is located at the right end of the synchronous belt, and a plurality of rubber blocking blocks and a rubber carrier shell are respectively located on the left side and the inner side of the baffle.

[0008] Furthermore, the first slide rail and the second slide rail are both gradually inclined downward from left to front to right, and the first slide rail is distributed in parallel with the second slide rail.

[0009] Furthermore, the synchronous belt, rubber carrier shell and rubber blocking block are vertically distributed with respect to the first slide rail and the second slide rail, the length and width of the placement cavity are greater than the diameter of the plastic syringe, and the width of the placement cavity is the same as the width of the sliding cavity.

[0010] Furthermore, a plurality of rubber blocking blocks and a rubber loading shell are located on the right side of the first slide rail and the second slide rail, and the width of the rubber blocking blocks is greater than the width of the sliding cavity.

[0011] Furthermore, the upper end of the rotating disk is fixedly connected to a fixing frame, the upper end of the fixing frame is fixedly connected to an electric telescopic rod, and the output end of the electric telescopic rod is fixedly connected to a pressure cover.

[0012] The utility model has the following beneficial effects:

[0013] Compared with the prior art, this plastic syringe filling and stoppering machine can store and transport plastic syringes that fall from between the first slide rail and the second slide rail through the mutual cooperation of the synchronous belt, the rubber carrier shell, the rubber blocking block and the baffle. During the transportation process, the plastic syringes are blocked by the baffle and will not fall easily until the rubber carrier shell drives the plastic syringes to rotate to the front end of the synchronous belt. The staff can manually remove the plastic syringes. In this way, the plastic syringes after liquid filling and stoppering can be more safely separated from the first slide rail and the second slide rail, and there is less risk of plastic syringes colliding with each other or colliding with the collection box due to automatic falling. In this way, the syringes that are finally removed and manually placed inside the collection box are of more qualified quality and less likely to be deformed, so as to facilitate subsequent normal use.

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0021] Reference Figure 1-4The utility model provides a plastic syringe filling and plugging machine, comprising a rotating disk 1, a first slide rail 7 and a second slide rail 8. A plurality of flip blocks 2 are installed on the circumferential surface of the rotating disk 1. Two mechanical clamping hands 3 are connected to the interior of each flip block 2. The bottom ends of the first slide rail 7 and the second slide rail 8 are fixedly connected to a first supporting leg 18 and a second supporting leg 17. The second supporting leg 17 is located at the right end of the first supporting leg 18. The first slide rail 7 and the second slide rail 8 are both located at the right end of the rotating disk 1. A sliding cavity 9 is provided between the first slide rail 7 and the second slide rail 8. A plastic syringe 12 is slidably connected to the interior of the sliding cavity 9. The front and rear ends of the second supporting leg 17 are fixedly connected to the first supporting leg 18. A support frame 16 is fixedly connected, and a baffle 15 is fixedly connected to the upper ends of the two support frames 16. A driving roller 20 is rotatably connected to the inside of the two support frames 16. The two driving rollers 20 are connected by a synchronous belt 13. The outer surface of the synchronous belt 13 is fixedly connected with a plurality of rubber carrier shells 14 and a plurality of rubber blocking blocks 22. The plurality of rubber carrier shells 14 and the rubber blocking blocks 22 are cross-distributed. A placement cavity 19 is opened on the upper end surface of each rubber carrier shell 14, and the placement cavity 19 is used to place the plastic syringe 12. A motor 21 is fixedly connected to the bottom end of the rear support frame 16, and the output shaft end of the motor 21 is fixedly connected to the driving roller 20 at the rear end.

[0022] During operation, the utility model allows operators to manually remove the plastic syringes 12 that have been filled, liquid added and stoppered, so that the plastic syringes 12 finally collected are of higher quality and less likely to be deformed or damaged due to collision between the plastic syringes 12, thereby facilitating subsequent normal use.

[0023] In one embodiment, if Figure 2 As shown, the upper end surfaces of the first slide rail 7 and the second slide rail 8 are both provided with a mounting groove 11, and a plurality of rollers 10 are rotatably connected inside the mounting groove 11. During operation, when the plastic syringe 12 slides down along the first slide rail 7 and the second slide rail 8, it will directly contact the rollers 10, so that the plastic syringe 12 slides down more smoothly. At the same time, under the action of the rollers 10, the friction between the plastic syringe 12 and the first slide rail 7 and the second slide rail 8 is smaller, and the wear on the surface of the plastic syringe 12 is less.

[0024] Further, the first slide rail 7 and the second slide rail 8 are gradually inclined downward from left to front and right, and the first slide rail 7 is parallel to the second slide rail 8. During operation, it is convenient for the plastic syringe 12 to slide down from left to right along the first slide rail 7 and the second slide rail 8.

[0025] In one embodiment, if Figure 3As shown, the baffle 15 is L-shaped and is located at the right end of the synchronous belt 13. A plurality of rubber stoppers 22 and the rubber carrier shell 14 are respectively located on the left side and the inner side of the baffle 15. During operation, until the rubber carrier shell 14 rotates to the right side of the synchronous belt 13, the baffle 15 can prevent the plastic syringe 12 in the placement cavity 19 from falling off, so that the operator can manually remove the plastic syringe 12 later.

[0026] Furthermore, the synchronous belt 13, the rubber carrier shell 14 and the rubber blocking block 22 are all distributed vertically to the first slide rail 7 and the second slide rail 8, the length and width of the placement cavity 19 are greater than the diameter of the plastic syringe 12, and the width of the placement cavity 19 is the same as the width of the sliding cavity 9; multiple rubber blocking blocks 22 and the rubber carrier shell 14 are all located on the right side of the first slide rail 7 and the second slide rail 8, and the width of the rubber blocking block 22 is greater than the width of the sliding cavity 9.

[0027] During operation, when the placement cavity 19 and the sliding cavity 9 are in an offset state, and the rubber blocking block 22 is blocked at the right end of the sliding cavity 9, the plastic syringe 12 located inside the sliding cavity 9 will not arbitrarily detach from the sliding cavity 9 and fall off, until the position of the sliding cavity 9 corresponds to that of the placement cavity 19, the plastic syringe 12 that slides off the first slide rail 7 and the second slide rail 8 will smoothly enter the placement cavity 19, so that the subsequent rotation of the synchronous belt 13 and the rubber carrier shell 14 will drive the plastic syringe 12 to be transported away from the first slide rail 7, until the rubber carrier shell 14 drives the plastic syringe 12 to rotate to the front end of the synchronous belt 13, and the staff can manually remove the plastic syringe 12.

[0028] In one embodiment, if Figure 1 As shown, the upper end of the rotating disk 1 is fixedly connected to a fixing frame 4, the upper end of the fixing frame 4 is fixedly connected to an electric telescopic rod 5, and the output end of the electric telescopic rod 5 is fixedly connected to a pressure cover 6.

[0029] In the present invention, the first slide rail 7, the second slide rail 8, the rotating disk 1, the mechanical clamping hand 3 and the flip block 2 are all components of the existing plastic syringe filling and plugging machine (all of which are prior art). In the existing equipment, after the plastic syringe 12 is loaded with the existing plastic syringe filling and plugging machine, it will be clamped and fixed by the mechanical clamping hand 3, and the rotating disk 1 will rotate at the same time. During the rotation process, the filling, liquid addition and plugging process are gradually completed (the filling components and plugging components are not shown in the figure). When the rotating disk 1 and the mechanical clamping hand 3 After driving the plastic syringe 12 to rotate to the lower end of the pressure cover 6, the electric telescopic rod 5 operates to drive the pressure cover 6 to press down again, so that the plug can be pressed more tightly into the plastic syringe 12, and then the rotating disk 1 rotates again, and at the same time the flip block 2 drives the mechanical clamping hand 3 to rotate, and drives the plastic syringe 12 to rotate, so that the piston end of the plastic syringe 12 is completely facing upwards, and the plastic syringe 12 is facing the sliding cavity 9, then the mechanical clamping hand 3 is released, and the plastic syringe 12 is located in the sliding cavity 9, and finally slides down along the first slide rail 7 and the second slide rail 8.

[0030] Working principle:

[0031] During use, after the plastic syringe 12 is filled with liquid and plugged, and slides down along the first slide rail 7 and the second slide rail 8, the motor 21 drives the drive roller 20 to rotate, and the synchronous belt 13 rotates, and the synchronous belt 13 drives the rubber carrier shell 14 and the rubber blocking block 22 to rotate, until the sliding cavity 9 corresponds to the position of the placement cavity 19, the plastic syringe 12 that slides down from the first slide rail 7 and the second slide rail 8 will smoothly enter the placement cavity 19, so that the synchronous belt 13 and the rubber carrier shell 14 will rotate and drive the plastic syringe 12 to be transported away from the first slide rail 7, until the rubber carrier shell 14 drives the plastic syringe 12 to rotate to the front end of the synchronous belt 13, and the staff can manually remove the plastic syringe 12.

[0032] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
