[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] The above technical solution is provided with a blocking block and a locking assembly.

At this time, the sodium hyaluronate repair dressing flowing inside the feed pipe will push the blocking block downward to seal the top of the filling head, preventing the sodium hyaluronate repair dressing from continuing to be filled in the vial, thereby achieving the purpose of quantitative filling of the vial and meeting the strict regulations on the filling of each bottle of sodium hyaluronate repair dressing.
[0022] The present invention provides an exhaust component and a shielding component. Through the design of the exhaust component, when the sodium hyaluronate repair dressing filled in the vial is full, the internal gas is pushed to be discharged unidirectionally through the exhaust component, thereby achieving the purpose of exhaust. When the trigger component is squeezed and pushed by the liquid surface, it drives the shielding component to seal the inside of the exhaust groove to prevent the sodium hyaluronate repair dressing from being discharged through the exhaust groove. Finally, the gas inside the vial is fully discharged, ensuring that the sodium hyaluronate repair dressing can be smoothly and quantitatively filled.
[0023] The present invention provides a reminder component and a reminder sound piece. When the blocking block blocks the top of the filling head downward, the sodium hyaluronate repair dressing inside one end of the feed pipe can be filled with the squeezing and driving reminder component to hit the reminder sound piece. The reminder sound piece will be affected by the impact force and shake back and forth to make a violent sound, thereby promptly reminding the operator to close the feed mechanism and stop feeding the sodium hyaluronate repair dressing into the feed pipe, and can directly guide it back, so as to avoid the feed mechanism from running all the time to feed the sodium hyaluronate repair dressing, causing one end of the feed pipe to burst.

DETAILED DESCRIPTION
[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.
[0034] like Figures 1 to 8As shown, the present invention provides an automatic filling device for the production of sodium hyaluronate repair dressing, comprising a processing table 1; a rotating disk 3, which is arranged at the middle of the top of the processing table 1; a lifting mechanism 4, which is arranged at the top of the processing table 1 and is located on the back of the rotating disk 3; a filling head 7, which is arranged at the top of the front end of the lifting mechanism 4; a blocking mechanism 9, which includes a cylinder 901, the cylinder 901 is fixedly installed inside the lifting mechanism 4 and is located outside the top of the filling head 7, the surface of the cylinder 901 is movably sleeved with a mounting frame 902, the bottom end of the middle part of the mounting frame 902 is provided with a blocking block 903, the mounting frame 902 is elastically connected to the inside of the lifting mechanism 4 through a reset spring 904, and trigger components 10 are arranged on both sides of the bottom of the filling head 7, and the lifting mechanism 4 is provided with a locking component 11 located outside the mounting frame 902.
[0035] When the sodium hyaluronate repair dressing in the vial is filled with squeezing, the trigger assembly 10 drives the locking assembly 11 to release the fixing effect of the mounting frame 902 and the blocking block 903, so that the sodium hyaluronate repair dressing on the top of the blocking block 903 can be pushed downward to block the top of the filling head 7, thereby stopping the filling.
[0036] like Figure 1 As shown, a conveying mechanism 2 located outside the rotating disk 3 is provided on the top of the processing table 1, and a feeding mechanism 5 located on the back of the lifting mechanism 4 is provided on the top of the processing table 1. The feeding mechanism 5 is fixedly connected to the top of the filling head 7 through a feeding pipe 6.
[0037] The above scheme is adopted: by providing a feeding mechanism 5, when the operator starts the feeding mechanism 5, the sodium hyaluronate repair dressing can be introduced into the filling head 7 through the feeding pipe 6, and then the inside of the vial can be filled through the filling head 7.
[0038] like Figure 1 As shown, a top cover mechanism 8 located in the middle of the back side of the rotating disk 3 is fixedly installed on the top of the processing table 1 .
[0039] The above scheme is adopted: by providing a cover mechanism 8, when the vial is filled and rotated by the rotating disk 3 to the bottom of the front end of the cover mechanism 8, the cover mechanism 8 can be started to seal the top of the vial, and then it can be transported away by the conveying mechanism 2 on the other side.
[0040] like Figure 3 and Figure 4 As shown, there are two return springs 904 , and the two return springs 904 are symmetrical about the center of the blocking block 903 .
[0041] The above solution is adopted: by providing a reset spring 904, when the elastic force of the reset spring 904 is released, the top of the blocking block 903 loses the squeezing force of the sodium hyaluronate repair dressing, which can push the mounting frame 902 and the blocking block 903 to reset upward as a whole.
[0042] like Figure 5 As shown, the trigger assembly 10 includes a first hydraulic cylinder 101, a trigger piston rod 102 and an oil passage 103;
[0043] The first hydraulic cylinder 101 is arranged on the outer side of the top of the filling head 7 , and the trigger piston rod 102 is movably installed in the inner cavity of the first hydraulic cylinder 101 . The first hydraulic cylinder 101 is connected to the outer side of the bottom end of the locking assembly 11 through the oil channel 103 .
[0044] By adopting the above solution, the trigger piston rod 102 is provided. When the trigger piston rod 102 is pushed upward, the hydraulic oil in the top inner cavity of the first hydraulic cylinder 101 can be transported to the locking assembly 11 through the oil passage 103 .
[0045] like Figure 7 As shown, the locking assembly 11 includes a second hydraulic cylinder 1101, a hydraulic piston rod 1102, a linkage arm 1103 and a locking block 1104;
[0046] The second hydraulic cylinder 1101 is fixedly installed inside the lifting mechanism 4 and is located outside the cylinder 901. The hydraulic piston rod 1102 is movably installed in the inner cavity of the second hydraulic cylinder 1101. The locking block 1104 is movably installed inside the lifting mechanism 4, and the inner end is located inside the outer side of the mounting frame 902. The linkage arm 1103 is hinged between the top of the hydraulic piston rod 1102 and the outer side of the locking block 1104.
[0047] The above solution is adopted: by providing a linkage arm 1103, when hydraulic oil enters the top inner cavity of the second hydraulic cylinder 1101, the second hydraulic cylinder 1101 is pushed as a whole, so that the linkage arm 1103 deflects and drives the two locking blocks 1104 away from each other, thereby releasing the locking fixation of the mounting frame 902.
[0048] like Figure 5 and Figure 6 As shown, the filling head 7 is provided with an exhaust assembly 12 located outside the first hydraulic cylinder 101, and the exhaust assembly 12 includes an exhaust groove 1201, a one-way valve column 1202 and a first connecting spring 1203;
[0049] The exhaust groove 1201 is opened inside the filling head 7 and located outside the first hydraulic cylinder 101. The exhaust groove 1201 is movably installed at the bottom inside the exhaust groove 1201. The one-way valve column 1202 is elastically connected to the inside of the exhaust groove 1201 through the first connecting spring 1203.
[0050] By adopting the above scheme: the elastic force of the first connecting spring 1203 can push the one-way valve column 1202 to move downward as a whole, so that external gas cannot enter, and the gas inside the syringe bottle can be discharged from the inside of the cylinder 901 by pushing the one-way valve column 1202 upward.
[0051] like Figure 5 As shown, a shielding assembly 13 is provided inside the filling head 7 between the first hydraulic cylinder 101 and the exhaust groove 1201, and the shielding assembly 13 includes a pneumatic cylinder 1301, a material blocking piston rod 1302 and an exhaust groove 1303;
[0052] The pneumatic cylinder 1301 is opened inside the filling head 7 and is located between the first hydraulic cylinder 101 and the exhaust groove 1201. The material blocking piston rod 1302 is movably installed in the inner cavity of the pneumatic cylinder 1301. The pneumatic cylinder 1301 is connected to the bottom end of the first hydraulic cylinder 101 through the ventilation groove 1303.
[0053] The above scheme is adopted: by providing a material-blocking piston rod 1302, when the piston rod 102 is triggered to move upward as a whole, a negative pressure can be generated in the inner cavity at the bottom of the first hydraulic cylinder 101 to draw out the gas in the outer inner cavities of the two pneumatic cylinders 1301, thereby driving the two material-blocking piston rods 1302 to move in opposite directions, so that the outer end of the material-blocking piston rod 1302 can block the bottom of the one-way valve column 1202.
[0054] like Figure 8 As shown, the interior of the lifting mechanism 4 is provided with a reminder component 14 located outside the feeding pipe 6, and the reminder component 14 includes a movable block 1401, a linkage frame 1402, a knocking frame 1403 and a second connecting spring 1404;
[0055] The movable block 1401 is movably installed on the inner wall of the lifting mechanism 4 and is located on the outside of one end of the feed pipe 6. The knocking frame 1403 is movably installed on the top of the lifting mechanism 4 and on one side of the linkage frame 1402. The top of the lifting mechanism 4 is provided with a reminder sound piece 15 located on one side of the knocking frame 1403. The knocking frame 1403 is elastically connected to the bottom end of the reminder sound piece 15 through a second connecting spring 1404.
[0056] By adopting the above solution: by providing a knocking frame 1403, when the two movable blocks 1401 move away from each other, the linkage frame 1402 can move away from each other, and the inclined surface on one side can squeeze the outer inclined surface of the knocking frame 1403, so that the knocking frame 1403 moves to one side and hits the top of the reminder sounder 15.
[0057] like Figure 8 As shown, the top of the reminder sounder 15 is made of metal.
[0058] The above scheme is adopted: since the reminder sound piece 15 is supported by metal, the reminder sound piece 15 can be shaken and produce sound, which can successfully remind the operator that the inside of the syringe bottle is full of a certain amount of sodium hyaluronate repair dressing, so as to control the feeding mechanism 5 to transport the sodium hyaluronate repair dressing inside the feeding pipe 6 back.
[0059] The working principle and use process of the present invention:
[0060] First, the operator can start the conveying mechanism 2 on one side to convey the vial to one side of the rotating disk 3, and then the rotating disk 3 can rotate to convey the designated vial to the bottom of the filling head 7. At this time, the lifting mechanism 4 can be started to drive the filling head 7 as a whole to be inserted downward into the vial, and then the feeding mechanism 5 can be started to pass the sodium hyaluronate repair dressing through the feeding pipe 6 into the filling head 7 to fill the vial.
[0061] Afterwards, when the sodium hyaluronate repair dressing inside the vial is full, the gas inside the vial is pushed into the exhaust groove 1201 and pushes the one-way valve column 1202 upward until it is completely discharged to the outside through the exhaust groove 1201. At the same time, the sodium hyaluronate repair dressing will squeeze and push the trigger piston rod 102 upward as a whole, so that negative pressure is generated in the inner cavity at the bottom of the first hydraulic cylinder 101 and the gas in the outer inner cavity of the pneumatic cylinder 1301 is extracted through the ventilation groove 1303, so as to drive the two material blocking piston rods 1302 to move in opposite directions, so as to cover the bottom end of the one-way valve column 1202.
[0062] Then, when the piston rod 102 is triggered upward, the hydraulic oil in the top inner cavity of the first hydraulic cylinder 101 will be pushed into the top cavity of the second hydraulic cylinder 1101 through the oil channel 103, so that the top cavity is filled with hydraulic pressure and the hydraulic piston rod 1102 is pushed downward as a whole. Then, the linkage arm 1103 will be deflected and the two locking blocks 1104 will move in opposite directions until they are completely separated from the outside of the mounting frame 902, thereby releasing the fixing effect on the mounting frame 902 and the blocking block 903. After that, the sodium hyaluronate repair dressing on the top of the blocking block 903 will push the blocking block 903 downward to block the top of the filling head 7.
[0063] When the sodium hyaluronate repair dressing on the top of the blocking block 903 and the inner cavity of one end of the delivery tube 6 are filled with, the two movable blocks 1401 and the linkage frame 1402 can be squeezed to move in opposite directions, and the knocking frame 1403 can be squeezed to move to one side as a whole, and the middle part of the top of the knocking frame 1403 will hit the reminder sounder 15 and make a loud sound to remind the operator that the sodium hyaluronate repair dressing inside the syringe bottle is filled, and the delivery mechanism 5 can be started to guide the sodium hyaluronate repair dressing in the delivery tube 6 and the syringe bottle back.
[0064] Ultimately, the same amount of sodium hyaluronate repair dressing can be smoothly filled into the vials, thereby successfully meeting the strict requirement that the amount of sodium hyaluronate repair dressing in each bottle be the same, greatly improving the filling quality of the sodium hyaluronate repair dressing.
