Description

Technical Field

[0001] The utility model relates to the technical field of filling, in particular to an injection liquid filling machine. Background Technique

[0002] At present, in the process of drug processing, a filling machine is an important production device. When medical injection liquid is produced and processed, the inside of a medicine bottle will be filled through a filling device. When the existing filling pipe finishes filling, the self-control device of the filling device will seal the filling channel by closing an electromagnetic valve. However, the liquid medicine near the inner port of the filling pipe cannot be sealed in time, resulting in the situation that the residual liquid medicine easily enters the medicine bottle and causes an overabundant situation, leading to unqualified filling standards and affecting the quality of subsequent finished products. For this reason, we propose an injection liquid filling machine. Content of the Utility Model

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides an injection liquid filling machine.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme. An injection liquid filling machine includes a filling pipe connected to a filling device. A plugging groove is opened at the bottom of the filling pipe. A plug is arranged inside the plugging groove. A round shaft penetrating the inside of the filling pipe is installed at the top of the plug. A support kit is sleeved outside the round shaft and is supported and connected to the inner wall of the filling pipe. A limiting member is installed at the end of the round shaft. A first spring is sleeved outside the round shaft and is supported and connected between the support kit and the limiting member. The bottom of the plug is installed with a sealing bottom sheet through a first connecting member, and the sealing bottom sheet can seal the bottom of the filling pipe.

[0005] Preferably, when the top of the plug contacts the liquid medicine, the plug moves downward, and the plug and the inside of the plugging groove are in an open state. When there is no extrusion force on the plug, the plug moves upward through the first spring and is in a mutually encapsulated state with the plugging groove.

[0006] Preferably, when the top of the plug contacts the liquid medicine, the plug moves downward, and the sealing bottom sheet is separated from the end of the filling pipe. When there is no extrusion force on the plug, the sealing bottom sheet moves upward through the plug and is in a secondary sealing state with the end of the filling pipe.

[0007] Preferably, an assembly cover is sleeved outside the filling pipe. An inner clamping member that can be sleeved with an external bottle mouth is arranged inside the assembly cover. The inner clamping member is of an arc-shaped structure. An introduction groove for facilitating the introduction of the bottle mouth is opened at the bottom of the assembly cover.

[0008] Preferably, circular holes are formed in the periphery of the assembly cover. A sliding rod passing through the circular holes is installed on the outer side of the inner clamping member. A second connecting member is installed at the end of the sliding rod. A second spring that supports and connects with the periphery of the assembly cover is sleeved on the outer part of the sliding rod.

[0009] Beneficial effects

[0010] The utility model provides an injection liquid filling machine, which has the following beneficial effects:

[0011] (1). For the injection liquid filling machine, in this solution, a plug is arranged in a blocking groove at the inner position of the port of the filling pipe. When the liquid medicine in the filling pipe is sprayed out during filling, the liquid medicine will squeeze and contact the plug inside the port of the filling pipe, causing the plug to quickly move downward and leave the inside of the filling pipe. Then, the filling pipe will enter the inside of the bottle mouth through an external lifting device for filling operation. When the high-pressure liquid medicine transportation inside the filling pipe stops, the plug will quickly reset elastically through the first spring and move upward to block the inside of the blocking groove, avoiding the leakage of the liquid medicine near the port inside the filling pipe due to untimely sealing, thereby achieving the effect of improving the subsequent filling quality of the liquid medicine bottle.

[0012] (2). For the injection liquid filling machine, an assembly cover is sleeved outside the filling pipe. An inner clamping member that can move is arranged inside the assembly cover. When the filling pipe moves downward into the inside of the bottle mouth, the assembly cover also moves downward and is sleeved with the bottle mouth end. When the bottle mouth enters, the inner clamping member will be squeezed and opened. When the inner clamping member is squeezed and moves, it can apply the rebounding force to the bottle mouth end through the extrusion of the second spring and limit and clamp the sleeved bottle mouth, avoiding the situation of the medicine bottle shaking when the traditional filling mechanism contacts the medicine bottle, thereby achieving the effect of improving the filling stability of the medicine bottle.

[0022] The working principle of the present utility model:

[0023] In this solution, a plug 3 for plugging is arranged in the plugging groove 2 at the internal position of the port of the filling pipe 1. When the liquid medicine in the filling pipe 1 is canned and sprayed out, the liquid medicine will be in extrusion contact with the plug 3 inside the port of the filling pipe 1, causing the plug 3 to quickly move downward and leave the inside of the filling pipe 1. The filling pipe 1 will enter the inside of the bottle mouth through an external lifting device for filling operation. When the high-pressure delivery of the liquid medicine inside the filling pipe 1 stops, the plug 3 will quickly reset elastically through the first spring 7 without the extrusion of the liquid medicine and move upward to plug the inside of the plugging groove 2, avoiding the leakage situation of the liquid medicine near the port inside the filling pipe 1 due to untimely sealing, thereby improving the subsequent canning quality of the liquid medicine bottle. An assembly cover 10 is sleeved outside the filling pipe 1, and a movable inner clamping member 11 is arranged inside the assembly cover 10. When the filling pipe 1 moves downward into the inside of the bottle mouth, the assembly cover 10 also moves downward and is sleeved with the bottle mouth end. When the bottle mouth enters, the inner clamping member 11 will be squeezed and opened. When the inner clamping member 11 is squeezed and moved, the rebounding force can be pressurized on the bottle mouth end through the extrusion of the second spring 16 to limit and clamp the sleeved bottle mouth, thereby improving the canning stability of the medicine bottle.
