Description

Technical Field

[0001] This application relates to the field of lubricant filling technology, and in particular to a medical lubricant filling device. Background Technology

[0002] Medical lubricants, as indispensable auxiliary materials in the field of medical devices, are widely used in the operation of surgical instruments, catheters, endoscopes, and other equipment. Their core function is to reduce friction between instruments and human tissue, improving the smoothness and safety of the operation. With the popularization of minimally invasive surgical techniques and the increasing sophistication of medical devices, the market demand for medical lubricants continues to grow, while higher requirements are being placed on their production quality, aseptic performance, and biocompatibility with instruments. In the production process of medical lubricants, the filling stage is a key step connecting raw material preparation and the end product; its efficiency, precision, and aseptic control level directly affect the final quality of the product.

[0003] However, current medical lubricant filling equipment uses traditional filling technology that lacks bottle mouth positioning and has low positioning accuracy. This makes it difficult to achieve precise alignment between the bottle mouth and the filling head during the filling process, resulting in poor contact between the filling head and the bottle mouth. This leads to problems such as liquid splashing and leakage, increasing lubricant waste and product scrap rate. Therefore, this technology needs to be improved. Utility Model Content

[0004] To address the issue of low positioning accuracy in traditional filling technologies, this application provides a medical lubricant filling device.

[0005] The medical lubricant filling device provided in this application adopts the following technical solution:

[0006] A medical lubricant filling device includes a main frame, on which a conveyor chain mechanism is provided. A plurality of filling heads are located at the top of the main frame. These filling heads are collectively provided with a supply mechanism and a lifting mechanism for supplying lubricant and for lifting operations. A positioning mechanism for positioning bottles is provided on the main frame. The positioning mechanism includes a positioning cylinder and a positioning plate. The positioning plate is positioned below the filling heads and has a plurality of positioning arc grooves that are spaced apart and sequentially formed on the positioning plate. Each positioning arc groove corresponds to one of the filling heads. The positioning cylinder is located on the main frame, and its output end is connected to one side of the positioning plate.

[0007] Because current medical lubricant filling equipment uses traditional filling technology that lacks bottle mouth positioning and has low positioning accuracy, it is difficult to achieve precise alignment between the bottle mouth and the filling head during the filling process. This results in poor contact between the filling head and the bottle mouth, causing problems such as liquid splashing and leakage, increasing lubricant waste and product scrap rate. By adopting the above technical solution, including a main frame, a conveyor chain plate mechanism is installed on the main frame, the filling head is arranged on the top of the main frame through a supply mechanism and a lifting mechanism, and a positioning mechanism is installed on the main frame. The positioning mechanism includes a positioning cylinder and a positioning plate, and several positioning arc grooves are opened on the positioning plate.

[0008] When filling hospital lubricants, the bottle to be filled is placed on the conveyor chain mechanism. The bottle moves forward with the conveyor chain mechanism. When the bottle moves below the filling head, the conveyor chain mechanism temporarily stops, waiting for the positioning mechanism to position it. The positioning cylinder is activated, pushing the positioning plate towards the conveyor chain mechanism, so that the positioning groove on the positioning plate contacts the bottle. The positioning groove fits tightly against the bottle mouth, fixing the bottle in the correct position and ensuring precise alignment between the bottle mouth and the filling head. The lifting mechanism is then activated, causing the filling head to descend. This ensures that the outlet of the filling head makes close contact with the bottle mouth. The supply mechanism continues to deliver lubricant to the filling head, which is then injected into the bottle body. After filling is completed, the lifting mechanism drives the filling head to rise, separating the filling head from the bottle mouth. The positioning cylinder is then activated in the reverse direction, causing the positioning plate to reset and the positioning arc groove to separate from the bottle body. The conveyor chain plate mechanism continues to move forward, transporting the filled bottle body to the next process and simultaneously transporting the next bottle body to be filled to the bottom of the filling head. This process is repeated to achieve continuous filling of multiple bottles.

[0009] By incorporating a conveyor chain mechanism and a positioning mechanism, the positioning accuracy is improved, ensuring that the bottle body is precisely fixed in the correct position. This effectively solves the problems of insufficient bottle mouth positioning and low positioning accuracy in traditional filling technologies. It ensures precise alignment between the bottle mouth and the filling head, avoiding problems such as liquid splashing and leakage caused by poor contact, reducing lubricant waste, improving product qualification rate, and reducing product scrap rate. It can continuously and efficiently fill multiple bottles, improving production efficiency and achieving a high degree of automation.

[0010] Optionally, the supply mechanism includes a plurality of supply hoses and a dispensing manifold. The dispensing manifold is arranged laterally on the main frame. The plurality of supply hoses correspond one-to-one with a plurality of filling heads. One end of the supply hose is connected to the filling head, and the other end of the supply hose is connected to the dispensing manifold.

[0011] By adopting the above technical solution, the supply mechanism includes several supply hoses and a distribution manifold. The lubricant is delivered to each supply hose through the distribution manifold. Through the setting of the supply mechanism, the lubricant can be evenly and stably distributed to each supply hose, ensuring that the flow rate of each filling head is consistent, avoiding the difference in filling volume caused by uneven flow, and improving the stability of product quality.

[0012] Optionally, a clamp for fixing is provided at the interface between any of the supply hoses and the manifold.

[0013] By adopting the above technical solution, the clamp is installed at the interface between the supply hose and the manifold. Through the clamp, the clamp uses mechanical pressure to tightly seal the interface between the supply hose and the manifold, eliminating the small gaps caused by pipeline vibration, pressure fluctuations or temperature changes, significantly reducing the risk of lubricant leakage and enhancing the sealing performance of the interface.

[0014] Optionally, the manifold is provided with a flow control valve for controlling the flow rate of lubricant, and the flow control valve is arranged at the inlet end of the manifold.

[0015] By adopting the above technical solution, the flow control valve is installed on the manifold; through the setting of the flow control valve, the total flow of lubricant can be adjusted in real time to ensure uniform distribution of each supply hose, avoid filling volume differences caused by pressure fluctuations, and improve filling accuracy.

[0016] Optionally, the main frame is provided with an assembly plate for fixing the manifold, and there are multiple assembly plates, which are arranged at intervals along the length of the manifold.

[0017] By adopting the above technical solution, the assembly plate is welded to the main frame, and the manifold is installed on the main frame through the assembly plate. By setting up the assembly plate, multiple assembly plates are arranged at intervals along the length of the manifold, which transforms the concentrated load into a uniformly distributed load, avoids bending or deformation of the manifold caused by single-point load, and improves the stability of the installation structure.

[0018] Optionally, the lifting mechanism includes a lifting plate, a lifting cylinder, a guide rod, and a guide sleeve. The lifting cylinder is vertically arranged on the top of the main frame, and the output end of the lifting cylinder is connected to the lifting plate. Several filling heads are sequentially connected below the lifting plate. The guide sleeve is fixedly connected to the top of the main frame, and the guide rod is slidably connected inside the guide sleeve. One end of the guide rod is connected to the lifting plate.

[0019] By adopting the above technical solution, the lifting mechanism includes a lifting plate, a lifting cylinder, a guide rod, and a guide sleeve; when the lifting cylinder is activated, the output end of the lifting cylinder extends and pushes the lifting plate downward, while the guide rod slides in the guide sleeve, restricting the lifting plate to move only in the vertical direction. The lifting plate drives the filling head to descend until it contacts the bottle mouth, thus completing the positioning.

[0020] The lifting mechanism facilitates the raising and lowering of the filling head. The lifting plate can complete the lowering / raising action in a very short time, achieving rapid response and efficient operation in high-speed automated production scenarios, thereby improving production efficiency.

[0021] Optionally, a blocking mechanism is provided on both sides of the conveyor chain plate mechanism. The blocking mechanism includes two blockers and a blocking rod. Both blockers are connected to the main frame and are respectively arranged at both ends of the conveyor chain plate mechanism in the length direction. The blocking rod is connected between the two blockers.

[0022] By adopting the above technical solution, the blocking mechanism is installed on both sides of the conveyor chain plate mechanism. The blocking mechanism includes two blockers and a blocking rod. With the setting of the blocking mechanism, the blockers are symmetrically distributed on both sides of the conveyor chain plate, and a protective structure is formed by the transverse blocking rod, which effectively blocks the risk of bottle container tipping over and tipping, and ensures the smooth operation of the filling process.

[0023] Optionally, each of the aforementioned blockers is provided with a blocking gripper for fixing the blocking rod, and an adjusting rod is provided on one side of the blocking gripper. The adjusting rod is slidably connected to the blocker, and the blocker is provided with a fastening bolt for fixing the adjusting rod.

[0024] By adopting the above technical solution, the blocker is fixed to the adjusting rod through the blocking claw, while the blocking claw slides on the blocker through the adjusting rod and is fixed by the fastening bolt. Through the setting of the blocking claw, adjusting rod and fastening bolt, the distance between the two blocking rods can be infinitely adjusted through the sliding connection, which can adapt to containers of different specifications without customization and improve the utilization rate of the equipment.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By incorporating a conveyor chain mechanism and positioning mechanism, the positioning accuracy is improved, ensuring that the bottle body is precisely fixed in the correct position. This effectively solves the problems of insufficient bottle mouth positioning and low positioning accuracy in traditional filling technologies, ensuring precise alignment between the bottle mouth and the filling head. It avoids problems such as liquid splashing and leakage caused by poor contact, reduces lubricant waste, improves product qualification rate, reduces product scrap rate, and enables continuous and efficient filling of multiple bottles, improving production efficiency and achieving a high degree of automation.

[0027] 2. The supply mechanism ensures that the lubricant is evenly and stably distributed to each supply hose, guaranteeing consistent flow rate at each filling head and avoiding differences in filling volume due to uneven flow, thereby improving product quality stability.

[0028] 3. By setting up a blocking mechanism, the blocking devices are symmetrically distributed on both sides of the conveyor chain plate, forming a protective structure through the horizontal blocking bars, effectively blocking the risk of bottle containers tipping over and ensuring the smooth operation of the filling process.

The number of positioning arc grooves 7 corresponds one-to-one with the number of filling heads 3.

[0044] The implementation principle of a medical lubricant filling device according to an embodiment of this application is as follows: When filling hospital lubricant, the bottle to be filled is placed on the conveyor chain mechanism 2. The bottle moves forward with the conveyor chain mechanism 2. When the bottle moves below the filling head 3, the conveyor chain mechanism 2 temporarily stops, waiting for the positioning mechanism 6 to perform positioning. The positioning cylinder 61 is activated, pushing the positioning plate 62 to move towards the conveyor chain mechanism 2, so that the positioning arc groove 7 on the positioning plate 62 contacts the bottle. The positioning arc groove 7 fits tightly with the bottle mouth of the bottle, fixing the bottle in the correct position and ensuring that the bottle mouth is precisely aligned with the filling head 3. The elevator... When mechanism 5 is activated, it drives the filling head 3 to descend, making the outlet of the filling head 3 in close contact with the bottle mouth. The supply mechanism 4 continues to supply lubricant to the filling head 3, and the lubricant is injected into the bottle body through the filling head 3. After filling is completed, the lifting mechanism 5 drives the filling head 3 to rise, making the filling head 3 separate from the bottle mouth. The positioning cylinder 61 is activated in the reverse direction, driving the positioning plate 62 to reset. The positioning arc groove 7 separates from the bottle body. The conveying chain plate mechanism 2 continues to move forward, and the conveying chain plate mechanism 2 transports the filled bottle body to the next process, while transporting the next bottle body to be filled to the bottom of the filling head 3. The steps are repeated to achieve continuous filling of multiple bottles.

[0045] By incorporating the conveyor chain mechanism 2 and the positioning mechanism 6, positioning accuracy is improved, ensuring that the bottle body is precisely fixed in the correct position. This effectively solves the problems of insufficient bottle mouth positioning and low positioning accuracy in traditional filling technology, ensuring precise alignment between the bottle mouth and the filling head 3.
