[0002] The liquid packaging machine, also known as the liquid filling machine, is an essential filling equipment in the production of liquid medicine.

[0003] When the liquid packaging machine fills the liquid medicine, since the liquid medicine itself has a low viscosity and the liquid filling pipe on the liquid packaging machine discharges liquid at the bottom end, during the process of changing the packaging bag or packaging bottle, the liquid medicine adhering to the inner wall of the liquid filling pipe will drip. In order to avoid the above situation, we hereby propose a filling equipment for the production of a new type of liquid medicine. Content of the Utility Model

[0004] The purpose of the utility model is to provide a filling equipment for the production of a new type of liquid medicine in order to avoid the situation of dripping during the process of switching the packaging bottle.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a filling equipment for the production of a new type of liquid medicine, including a liquid filling pipe, a fixed cylinder is sleeved on the outer wall of the liquid filling pipe, the fixed cylinder is fixedly connected with the liquid filling pipe, a plurality of liquid discharge holes communicating with the inner cavity of the fixed cylinder are circumferentially arranged on the outer wall of the fixed cylinder, a fixed bottom cover is sleeved at the bottom end of the fixed cylinder, and an anti-dripping mechanism is arranged below the liquid filling pipe, and the anti-dripping mechanism is used for the anti-dripping operation during liquid filling;

[0006] The anti-dripping mechanism includes:

[0007] A first push plate arranged on the lower surface of the liquid filling pipe, a connecting push rod is fixedly connected to the bottom end of the first push plate, a positioning cylinder fixedly connected with the fixed cylinder is sleeved on the outer wall of the connecting push rod, a second push plate is fixedly connected to the bottom end of the connecting push rod, and the second push plate is slidably connected with the positioning cylinder up and down.

[0008] As a further scheme of the utility model: the anti-dripping mechanism further includes:

[0009] A lifting sliding cylinder fixedly connected to the bottom end of the first push plate, the lifting sliding cylinder is located outside the second push plate and is slidably connected with the positioning cylinder up and down, and a plurality of liquid infusion grooves are circumferentially arranged at the top end of the positioning cylinder and outside the lifting sliding cylinder.

[0010] As a further scheme of the utility model: an external thread is arranged on the outer wall of the fixed cylinder, and an internal thread that is mutually consistent with the external thread on the outer wall of the fixed cylinder is arranged on the inner wall of the fixed bottom cover.

[0011] As a further solution of the utility model: a first sealing ring which is tightly attached to the inner wall of the fixed bottom cover is fixedly connected to the bottom end of the fixed cylinder.

[0012] As a further solution of the utility model: a spring is sleeved on the outer wall of the connecting push rod, and the two end parts of the spring are respectively in contact with the outer walls of the first push plate and the positioning cylinder.

[0013] As a further solution of the utility model: a liquid storage tank for the second push plate to slide up and down is arranged inside the positioning cylinder, and both the liquid infusion tank and the liquid storage tank penetrate to the outside of the bottom end of the positioning cylinder and communicate with the inner cavity of the fixed bottom cover.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] By setting up an anti-drip mechanism, the liquid packaging machine discharges liquid into the fixed cylinder through the liquid filling pipe. At this time, under the pressure of the liquid, the first push plate pushes the second push plate to descend through the connecting push rod. At the same time, the first push plate pushes the lifting sliding cylinder to descend and compresses the spring to contract. At this time, the liquid inside the liquid filling pipe enters the fixed cylinder. At the same time, through the cooperation of the liquid infusion tank and the liquid storage tank, the liquid can be stored limitedly. When the liquid level is equal to the height of the liquid discharge hole, the liquid is infused into the packaging bag through the liquid discharge hole. When the infusion ends, the infusion of the liquid stops. At this time, the spring rebounds to push the first push plate to block the opening of the liquid filling pipe. At the same time, the second push plate is driven by the first push plate through the connecting push rod to reset. At this time, the liquid in the inner cavity of the liquid storage tank rises with the movement of the second push plate. At the same time, the liquid outside the lifting sliding cylinder moves into the liquid storage tank through the liquid infusion tank, so that the height of the liquid can automatically drop and be misaligned with the height of the liquid discharge hole, effectively avoiding the situation of liquid dripping during the process of changing the bag for infusion.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a filling device for the production of a new liquid drug includes a liquid filling tube 1. The outer wall of the liquid filling tube 1 is sleeved with a fixed cylinder 3. The fixed cylinder 3 is fixedly connected to the liquid filling tube 1. A plurality of drain holes 4 that communicate with the inner cavity of the fixed cylinder 3 are circumferentially formed on the outer wall of the fixed cylinder 3. The bottom end of the fixed cylinder 3 is sleeved with a fixed bottom cover 5. The outer wall of the fixed cylinder 3 is provided with an external thread, and the inner wall of the fixed bottom cover 5 is provided with an internal thread that matches the external thread on the outer wall of the fixed cylinder 3. A first sealing ring that is closely attached to the inner wall of the fixed bottom cover 5 is fixedly connected to the bottom end of the fixed cylinder 3. A drip prevention mechanism 2 is arranged below the liquid filling tube 1. The drip prevention mechanism 2 is used for preventing dripping during liquid filling;

[0023] The anti-drip mechanism 2 includes:

[0024] A first push plate 201 provided on the lower surface of the liquid filling tube 1. The bottom end of the first push plate 201 is fixedly connected to a connecting push rod 202. The outer wall of the connecting push rod 202 is sleeved with a positioning cylinder 205 fixedly connected to the fixed cylinder 3. The bottom end of the connecting push rod 202 is fixedly connected to a second push plate 204. The second push plate 204 is slidably connected to the positioning cylinder 205 up and down;

[0025] The anti-drip mechanism 2 further includes:

[0026] The lifting sliding cylinder 207 fixedly connected to the bottom end of the first push plate 201 is located outside the second push plate 204 and is slidably connected to the positioning cylinder 205 up and down. A plurality of liquid infusion grooves 206 are circumferentially formed at the top end of the positioning cylinder 205 and outside the circumferential side of the lifting sliding cylinder 207. A spring 203 is sleeved on the outer wall of the connecting push rod 202, and the two ends of the spring 203 are respectively in contact with the outer walls of the first push plate 201 and the positioning cylinder 205. A liquid storage groove 208 for the second push plate 204 to slide up and down is formed inside the positioning cylinder 205. The liquid infusion grooves 206 and the liquid storage groove 208 both penetrate to the outside of the bottom end of the positioning cylinder 205 and are mutually communicated with the inner cavity of the fixed bottom cover 5.

[0027] In this embodiment: When using this device, the fixed bottom cover 5 is threadedly connected to the fixed cylinder 3, so that the fixed bottom cover 5 can be fixed at the bottom end of the fixed cylinder 3. During this process, the first sealing ring deforms under the extrusion of the fixed bottom cover 5, so that the fixed cylinder 3 and the fixed bottom cover 5 are hermetically connected;

[0028] After that, the liquid packaging machine discharges liquid into the fixed cylinder 3 through the liquid filling pipe 1. At this time, under the pressure of the liquid, the first push plate 201 pushes the connecting push rod 202 and the lifting sliding cylinder 207 to synchronously descend along the inner wall of the positioning cylinder 205, and compresses the spring 203 to contract. At the same time, the second push plate 204 descends along the inner wall of the positioning cylinder 205 under the push of the connecting push rod 202. At this time, the liquid in the liquid filling pipe 1 enters the fixed cylinder 3 and passes through the liquid infusion grooves 206 into the liquid storage groove 208. At this time, the liquid storage groove 208 and the liquid infusion grooves 206 can store the liquid limitedly under the limitation of the second push plate 204. When the liquid level is equal to the height of the liquid discharge hole 4, the liquid is then infused into the packaging bag through the liquid discharge hole 4;

[0029] When the infusion is completed, the liquid discharge into the fixed cylinder 3 through the liquid filling pipe 1 is stopped at this time. At the same time, the spring 203 rebounds to push the first push plate 201 to reset. At this time, the first push plate 201 blocks the opening of the liquid filling pipe 1 through the sealing gasket to avoid continuous infusion of the liquid. At the same time, the second push plate 204 synchronously resets under the drive of the first push plate 201 through the connecting push rod 202. At this time, the liquid in the inner cavity of the liquid storage groove 208 rises as the second push plate 204 moves. At the same time, the liquid outside the lifting sliding cylinder 207 moves into the liquid storage groove 208 through the liquid infusion grooves 206, so that the height of the liquid can automatically drop and be misaligned with the height of the liquid discharge hole 4, effectively avoiding the situation of liquid dripping during the process of replacing the packaging bottle (or packaging bag);

[0030] When the liquid packaging machine is no longer in use, the fixed bottom cover 5 can be separated from the fixed cylinder 3 by rotation at this time, so that the liquid in the liquid storage groove 208 can be discharged and the residual liquid can be cleaned.

[0031] Please refer specifically to Figures 2 to 3 , a second sealing ring that is fixedly connected to the outer wall of the second push plate 204 and is closely attached to the inner wall of the liquid storage tank 208, a third sealing ring that is fixedly connected to the outer wall of the lifting sliding cylinder 207 and is closely attached to the inner wall of the positioning cylinder 205, and a gasket that is fixedly connected to the top end of the first push plate 201 and is closely attached to the inner wall of the liquid filling pipe 1.

[0032] In this embodiment: Through the second sealing ring and the third sealing ring, it can effectively prevent liquid from passing through the liquid storage tank 208, the second push plate 204, and between the positioning cylinder 205 and the lifting sliding cylinder 207 and coming into contact with the outer wall of the spring 203.

[0033] The above-mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
