Description

Technical Field

[0001] The invention relates to the technical field of syringes, and in particular to a dust removal device for the inner wall of a syringe barrel. Background Art

[0002] At present, the production process of syringes generally includes the following steps: injection molding → printing → oil injection → assembly → packaging.

[0003] During the entire production process of syringes, including the turnover between processes, foreign matter is easily adsorbed on the inner surface of the syringe. In particular, during the injection molding process before printing, white transparent powder will be adsorbed on the inner wall of the syringe, and the powder is often charged and difficult to fall off automatically under the influence of magnetic field. In addition, the transportation distance from injection molding to printing is long, and foreign matter is often easily adsorbed on the inner wall of the barrel.

[0004] In the syringe industry, the safety caused by foreign matter is mainly to conduct visual inspection of the barrel by CCD visual equipment before assembly. CCD inspection can only be performed on barrels of 20ml and above, and can only detect 50-80% of them, and cannot detect white particles, small particles, and transparent particles at all. It can only work on large foreign matter. Due to visual defects, many manufacturers mainly solve the process of syringe inner wall inspection by naked eye during the production process, which leads to extremely inaccurate inspection and poses a greater safety hazard to the syringe.

[0005] In the prior art, the visual inspection of the cylinder by CCD visual equipment before assembly is difficult to accurately judge small specifications and small particles due to the limitation of vision and the error rate.

[0006] Therefore, in view of this limitation, it is urgently necessary to develop and design a device for removing static electricity and dust from the inner wall of the syringe. The device uses ion wind dust removal to remove static electricity and dust from the inner wall of each syringe, and can collect foreign matter in a centralized manner. Summary of the invention

[0007] The purpose of the present invention is to solve the limitation of the existing syringes that it is difficult to accurately judge extremely small specifications and small particles through CCD visual equipment detection, and to provide a syringe inner wall dust removal device. The dust removal device uses ion wind dust removal to effectively remove static electricity and dust from the inner wall of the syringe, thereby ensuring the safety of the syringe. In addition, the device has a long dust removal time and can have enough time to discharge foreign matter. The discharged foreign matter can be collected in a centralized manner to ensure that there is no secondary pollution, and it can also effectively match the high-speed operation requirements of the roller printing machine.

The feeding mechanism 2 and the dust removal mechanism 3 adopt a meshing transmission mode to work synchronously to continuously transfer and remove dust from the syringe. The meshing transmission mode can be through gear meshing transmission, synchronous wheel external meshing transmission, sprocket transmission and other modes to achieve continuous feeding, static electricity removal and dedusting operations of the syringe. In this embodiment, a gear meshing transmission mode is adopted, which adopts a traditional gear meshing mode, and the feeding mechanism 2 and the dust removal mechanism 3 both adopt a gear meshing transmission 16. A universal wheel assembly 26 is also provided at the lower part of the frame to facilitate the overall movement of the device, so as to facilitate the use of different processes in the production line as needed.

[0053] An external frame 4 is also provided on the frame outside the dust removal mechanism 3, and a protective plate or protective glass can be provided on the external frame 4, so that the syringe can be de-staticized and dusted in a closed environment to maintain a good working environment.

The feed drive motor 51 is arranged inside the frame 1, and the feed drive motor output shaft 53 extends out of the frame table and cooperates with the feed drive bearing seat 52. The feed drive bearing seat 52 is fixed on the frame table.

[0058] like Figure 7 , Figure 8 As shown, the feed tray assembly 6 includes a feed tray 61 and a feed protection member 62 that cooperates with the feed tray 61 to realize feeding. Fig. 9 As shown, the feed tray 61 includes a tray rotating body 610, an upper feed tray 611 and a lower feed tray 612. The tray rotating body 610 cooperates with the output shaft 53 of the feed drive motor and is driven to rotate by the feed drive motor 51 to realize the sequential transmission of the syringe. The upper feed tray 611 and the lower feed tray 612 are arranged correspondingly up and down. A plurality of meshing transmission grooves 613 matching the outer diameter of the syringe are evenly distributed on the circumferential surfaces of the upper feed tray 611 and the lower feed tray 612. A guide circumferential surface 614 is arranged on the feed tray surface between adjacent meshing transmission grooves 613. The guide circumferential surface 614 is an inclined arc surface to ensure that the syringe is smoothly transmitted from the inside of the meshing transmission groove 613 during the transmission process. The spacing between the upper feed tray 611 and the lower feed tray 612 is less than the height of the syringe.

[0059] like Figure 7 , Figure 8As shown, the feed guard 62 includes a feed column 620 and a feed guard plate 621. One end of the feed column 620 is fixed on the frame table.

[0061] The dust removal drive device 7 can be a drive motor assembly or other commonly used drive devices. In this embodiment, the dust removal drive device 7 adopts a dust removal drive motor, such as Figure 2 As shown, the output shaft 71 of the dust removal driving motor 7 is vertically arranged upward and passes through the upper and lower lifting mechanism 8, the ion air gun mechanism 9, and the pressing valve assembly 10. Figure 6 As shown, the slip ring assembly 11 includes a slip ring fixing frame 110 and a slip ring 111. The slip ring fixing frame is connected to the output shaft 71 of the dust removal drive motor, and the slip ring 111 is slidably arranged in the slip ring fixing frame 110. A gas channel 112 connected to an external gas source and a push-type valve assembly is arranged inside the slip ring 111. The gas channel can be an air pipe or a channel directly arranged inside the slip ring, as long as the protective gas can enter from the upper end of the slip ring and be output from the lower end to enter the push-type valve assembly. The setting of the slip ring assembly can ensure the connectivity of the gas path, and will not affect the rotation of the dust removal drive device, and will not cause the problem of pipeline entanglement.

[0062] like Figure 5 As shown, the up-and-down lifting mechanism 8 mainly includes an up-and-down lifting rail 12 arranged on the frame table, a processing tray 14 arranged coaxially with the up-and-down lifting rail 12, and a plurality of lifting components 15 movably connected to the processing tray 14 up and down.

[0063] like Figure 6 As shown, the up and down lifting track 12 includes an integrally arranged annular track body 121 and an ascending inclined track 122 and a descending inclined track 123 arranged on the annular track body 121, a limited position surface 124 is arranged on the track surface of the ascending inclined track 122 and the descending inclined track 123, and a high point position processing surface 13 is arranged at the connection between the ascending inclined track 122 and the descending inclined track 123, and the length of the high point position processing surface 13 is greater than the length of the limiting surface, so that the processing time of the syringe electrostatic dust removal can be controlled.

[0064] like Figure 6 As shown, the processing disk 14 is fixedly connected to the dust removal drive device 7 through a matching seat 17 and is driven to rotate by the dust removal drive device 7. A plurality of sliding holes 141 are evenly distributed along the circumferential direction on the processing disk 14. The sliding holes 141 include an inner sliding hole 142 and an outer sliding hole 143. Sliding sleeves 144 are respectively arranged inside the inner sliding hole 142 and the outer sliding hole 143.

The connecting block 1511 is arranged in an L-shaped structure, including a vertical connecting edge and a horizontal connecting edge. The vertical connection is connected to the connecting shaft 154, and two connecting holes 1512 are arranged on the horizontal connecting edge corresponding to the sliding holes on the processing disk. The sliding assembly 152 includes two parallel sliding rods, the lower ends of the sliding rods are fixed inside the connecting holes, and the upper ends of the sliding rods are fixed inside the connecting holes. It passes through the sliding hole on the processing disk and is fixedly connected to the lower end surface of the lifting block, and drives the lifting block to move up and down in the vertical direction, so that it can realize the contact with the processing disk surface and gradually move away from the processing disk surface. When the roller assembly rotates with the processing disk to the high point processing surface 13, the distance between the lower surface of the lifting block 153 and the processing disk surface is the largest. When the lifting block 153 rotates from the high point processing surface 13 to the descending track surface, the distance between the lifting block 153 and the processing disk surface gradually decreases, and finally contacts with the processing disk surface.

[0066] like Fig. 9 As shown, the lifting block 153 is preferably made of nylon, but can also be made of polyester, etc. The lifting block 153 is coaxially arranged with the processing disk 14, and a plurality of lifting blocks 153 are enclosed to form a lifting ring. The lifting ring moves in sequence during the lifting process to form a cyclic floating curved surface structure. An active gap is arranged between two adjacent lifting blocks 153. A circumferential annular groove 1530 is arranged on the outer circumference of the lifting block 153. The circumferential annular groove 1530 is concavely arranged toward the center of the lifting block. The circumferential annular groove 1530 divides the lifting block 153 into two upper and lower guide annular surfaces 1531. An engaging limit groove 1532 is provided on the guide annular surface 1531. The height between the engaging limit grooves 1532 between the upper and lower guide annular surfaces 1531 is less than the height of the syringe. The engaging limit groove 1532 and the engaging transmission groove 613 both match the outer diameter of the syringe.

[0067] The horizontal plane when the lifting block 153 contacts the surface of the processing tray 14 is in the same horizontal plane as the horizontal plane of the surface of the feeding tray 61 .

[0068] A transfer gap is provided between the guide ring surface 1531 of the lifting block at the transfer point between the feed tray 61 and the processing tray 14 and the circumferential surface of the feed tray 61 to ensure that the syringe can be smoothly transferred from the feed tray to the lifting block on the processing tray and continued to rotate and transfer through the processing tray.

[0069] like Figure 4 As shown, an intermediate protective member 18 is arranged on the outer side of the lifting block 153 at the transition point between the feed tray 61 and the processing tray 14. The intermediate protective member 18 includes an intermediate protective member column 181 and an intermediate protective plate 182 arranged on the upper end of the intermediate protective member column 181. The intermediate protective plate 182 is arranged in an arc-shaped ring on the outer side of the outer circumference of the lifting block 153 and an intermediate transfer gap is arranged between the outer circumference of the lifting block. A matching transmission arc surface is arranged on the inner side of the intermediate protective plate 182.

[0070] like Figure 4 As shown, a lifting guard plate 19 is arranged on the outer side of the lifting block 153 above the ascending inclined track 122 and the descending inclined track 123.

[0078] The working principle of the dust removal device for the inner wall of the syringe barrel is as follows: the feed drive device drives the feed disk to rotate, and the syringes are sequentially transferred to the processing disk. The processing disk is driven by the division drive motor to continuously operate. The several lifting mechanisms on the processing disk perform lifting movements during the rotation process, lifting the syringe 25, and the plasma wind nozzle 923 penetrates into the inner wall of the syringe barrel. When at a specified height, the valve control inclined block 102 presses the push-type mechanical valve 101, and the push-type mechanical valve 101 moves and connects to the air. One end of the push-type mechanical valve 101 is connected to the slip ring 111, and the other end is connected to the plasma wind processor body 922. When the push-type mechanical valve 101 is connected, the plasma wind nozzle 923 sprays ion wind with plasma into the barrel of the syringe, quickly removes the charge on the inner wall of the barrel, and the dust on the inner wall is blown out of the barrel by the wind after being separated from the adsorption force of the charge. The blown foreign matter is absorbed and collected by vacuum to prevent secondary pollution, thereby realizing dust removal treatment on the inner wall of the syringe.

[0079] The inner wall dust removal device of the syringe barrel adopts the ion wind dust removal method to remove static electricity from the inner wall of each syringe and blow foreign matter out of the barrel. The length of the syringe static removal treatment method can be controlled by lifting the high point position on the track 12 up and down to process the surface 13, which can extend the treatment time and ensure sufficient treatment time. At the same time, the equipment can run continuously, and the processing speed can match the entire assembly line. At the same time, the syringes are processed one-to-one without omissions. It is guaranteed to keep up with the production capacity requirements of subsequent printing or the production capacity requirements of subsequent injection.
