[0003] In the production of erythromycin eye ointment, aseptic filling is a key step in ensuring product quality. However, existing aseptic filling devices for erythromycin eye ointment have many technical defects in practical applications: First, because erythromycin eye ointment uses an oil-based matrix, it has high viscosity and is prone to separation. Existing devices mostly only have a single conveying structure and lack an effective stirring mechanism, which leads to uneven product concentration after filling. Second, the stirring speed of existing devices is mostly fixed and cannot be flexibly adjusted according to the viscosity and composition characteristics of different batches of eye ointment. This results in poor versatility and makes it difficult to ensure that different batches of eye ointment achieve the ideal stirring effect. Utility Model Content

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0018] Reference Figures 1-4 This embodiment of the present invention provides an aseptic filling device for producing erythromycin eye ointment, comprising: The aseptic filling mechanism 100 includes an aseptic filling machine 110, a conveying pipe 120 fixed on the aseptic filling machine 110, and a conveying propeller 130 disposed inside the conveying pipe 120 for extruding and conveying erythromycin eye ointment. The stirring mechanism 200 includes a stirring component 210 for stirring the erythromycin eye ointment before filling to prevent uneven product concentration, and a transmission ratio adjusting component 220 used in conjunction with the stirring component 210 to adjust the stirring speed.

[0019] Among them, the stirring component 210 can effectively stir the erythromycin eye ointment before filling, fundamentally solving the problem of component stratification caused by standing of the eye ointment, and ensuring uniform product concentration after filling; the transmission ratio adjustment component 220 can flexibly adjust the stirring speed according to actual production needs, so that the stirring operation can be adapted to different batches and different viscosities of erythromycin eye ointment, improving the versatility and applicability of the device.

[0020] Specifically, the stirring component 210 includes a fixed block 211 fixed inside the conveying pipe 120, a slot 212 formed on the surface of the fixed block 211, a stirring rod 213 set on one side of the fixed block 211 for stirring the eye ointment, a drive wheel 214 fixed to the conveying propeller 130 and one end of the stirring rod 213 respectively, a drive belt 215 driven on the surface of the drive wheel 214, two protruding plates 216 fixed to the top of the conveying pipe 120, a linkage rod 217 rotatably installed between the two protruding plates 216, and two conical wheels 218 driven on the surface of the linkage rod 217 and connected to the drive belt 215. The surface of the fixed block 211 has several holes for the flow of eye ointment.

[0021] The holes on the surface of the fixed block 211 ensure that the eye ointment flows normally during the stirring process, and prevent the eye ointment from being obstructed by the setting of the stirring component 210. The stirring rod 213 can directly stir the eye ointment in the conveying pipe 120. With the transmission cooperation between the conveying propeller 130 and the end of the stirring rod 213 through the transmission wheel 214 and the transmission belt 215, the stirring rod 213 is synchronously driven to rotate by the power of the conveying propeller 130, without the need for an additional stirring drive source. It should be noted that the interior of the slot 212 is equipped with a pressure plate for tensioning the transmission belt 215.

[0022] Furthermore, the ends of the conveying propeller 130 and the stirring rod 213 extend into the interior of the empty trough 212, and the drive wheel 214 is located inside the empty trough 212.

[0023] The ends of the conveying propeller 130 and the stirring rod 213 are extended into the cavity 212 on the surface of the fixed block 211, and the transmission wheel 214 is located inside the cavity 212. This effectively isolates the transmission components such as the transmission wheel 214 and the transmission belt 215 from the eye ointment delivery area, preventing the transmission components from coming into direct contact with the eye ointment during operation.

[0024] Preferably, the surface of the fixed block 211 is provided with two sealed bearings 219, which are respectively sleeved on the ends of the conveying propeller 130 and the stirring rod 213 to increase the sealing of the interior of the empty trough 212.

[0025] Among them, the sealed bearing 219 can fill the gap between the conveying propeller 130, the stirring rod 213 and the fixed block 211, preventing the eye ointment from seeping into the interior of the empty trough 212 and contacting the transmission components during the conveying and stirring process. This avoids problems such as jamming and wear of the transmission components due to eye ointment contamination. At the same time, it also prevents impurities inside the empty trough 212 from entering the eye ointment conveying channel, ensuring the production quality of the eye ointment.

[0026] Furthermore, the transmission ratio adjustment component 220 includes a connecting circular plate 221 fixed to one side of the conical wheel 218, a plurality of C-shaped clamping plates 222 snapped onto the surface of the connecting circular plate 221 and used to drive the conical wheel 218 to move, a connecting rod 223 fixed to the surface of the C-shaped clamping plate 222, a transmission plate 224 fixed to the other end of the connecting rod 223, and a stud 225 rotatably mounted on one side of the convex plate 216 and used to drive the transmission plate 224 to move.

[0027] The C-shaped clamping plate 222 engages with the connecting circular plate 221, ensuring that the connecting circular plate 221 and the C-shaped clamping plate 222 move synchronously, thereby driving the conical wheel 218 to move axially along the linkage rod 217. The connecting rod 223 connects the C-shaped clamping plate 222 and the transmission plate 224 into one unit, so that the movement of the transmission plate 224 can be transmitted to the C-shaped clamping plate 222 through the connecting rod 223, ultimately realizing the position adjustment of the conical wheel 218. The rotating installation of the stud 225 and the convex plate 216 allows the transmission plate 224 to move by rotating the stud 225, making the operation simple and quick. By adjusting the position of the conical wheel 218 on the linkage rod 217, the contact position between the conical wheel 218 and the transmission belt 215 can be changed, thereby changing the transmission ratio and adjusting the stirring speed of the stirring rod 213. This allows the device to flexibly adjust the stirring intensity according to the actual viscosity and composition characteristics of the eye ointment, ensuring the stirring effect and avoiding the problem of insufficient or excessive stirring of some batches of eye ointment due to a fixed stirring speed.

[0028] Specifically, the surface of the transmission plate 224 is provided with a threaded hole for use with the stud 225, and the stud 225 passes through the threaded hole.

[0029] Furthermore, a number of positioning rods 226 are fixedly installed on one side of the convex plate 216, and a number of positioning holes are opened on the surface of the transmission plate 224, with the ends of the positioning rods 226 passing through the positioning holes.

[0030] The positioning rod 226 has its end passing through the positioning hole, forming a guide and positioning structure for the movement of the transmission plate 224. The positioning rod 226 can restrict the movement direction of the transmission plate 224, ensuring that the transmission plate 224 moves linearly only along the axial direction of the positioning rod 226 under the drive of the stud 225. This avoids problems such as offset or tilting of the transmission plate 224 during movement, and ensures that the force transmitted from the transmission plate 224 to the C-shaped clamping plate 222 through the connecting rod 223 is stable, thereby ensuring that the conical wheel 218 can move smoothly along the axial direction of the linkage rod 217.

[0031] During use, the required stirring speed is determined based on the viscosity and composition characteristics of the erythromycin eye ointment to be filled. The operator rotates the stud 225. Since the stud 225 is connected to the transmission plate 224 through a threaded hole, the rotation of the stud 225 drives the transmission plate 224 to move axially along the positioning rod 226. The transmission plate 224 drives the C-type clamping plate 222 to move through the connecting rod 223. The C-type clamping plate 222 drives the connecting circular plate 221 and the conical wheel 218 fixed thereto to move axially along the linkage rod 217, changing the contact position between the conical wheel 218 and the transmission belt 215, thereby adjusting the transmission ratio until the stirring rod 213 reaches the preset stirring speed, and the stud 225 is stopped from rotating. Start the aseptic filling machine 110, which drives the conveying propeller 130 inside the conveying pipe 120 to rotate. During the rotation, the conveying propeller 130 conveys the erythromycin eye ointment along the conveying pipe 120 towards the filling outlet through compression. At the same time, it drives the transmission belt 215 through the transmission wheel 214 at the end. The transmission belt 215, in cooperation with the conical wheel 218 and the transmission wheel 214 at the end of the stirring rod 213, drives the stirring rod 213 to rotate synchronously. When the stirring rod 213 rotates, it stirs the erythromycin eye ointment in the conveying pipe 120. During the stirring process, the eye ointment is continuously conveyed forward through the holes on the surface of the fixed block 211 to prevent the components from separating.

[0032] In summary, the stirring component 210 can effectively stir the erythromycin eye ointment before filling, fundamentally solving the problem of component stratification caused by standing of the eye ointment, and ensuring uniform product concentration after filling; the transmission ratio adjustment component 220 can flexibly adjust the stirring speed according to actual production needs, so that the stirring operation can be adapted to different batches and different viscosities of erythromycin eye ointment, improving the versatility and applicability of the device.
