Description

Technical Field

[0001] This utility model relates to the field of filling technology, specifically to a plastic filling and dispensing component for a filling machine. Background Technology

[0002] With the development of mechanical automation, filling machines, as a type of packaging machine, are widely used in the field of fluid dispensing. They can dispense a large number of uniformly produced products according to different dispensing bottle capacity specifications, which can greatly improve production efficiency and save labor costs. Therefore, higher requirements are placed on the performance and adaptability of its various components, including the discharge part.

[0003] Most existing filling accessories for discharge ports are made of metal. After long-term use, friction between metal parts may generate tiny debris that can mix into the material, causing contamination and posing safety risks. In addition, metal materials themselves are expensive and require high precision machining costs, resulting in high production costs and poor practicality when large-scale filling is needed. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a plastic filling and dispensing component for a filling machine, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a plastic filling and discharging component for a filling machine, including a filling body, a cylinder, and a discharge port located at the bottom of the filling body. A feed port is fixedly installed on one side of the filling body. Filling accessories are provided inside the filling body. A piston is fixedly installed on the top of the inner wall of the filling body and fixedly installed with the movable end of the cylinder. A connecting flange two is fixedly installed on the end of the filling body near the discharge port. A locking bolt is provided on the side of the connecting flange two away from the filling body.

[0006] The filling accessory includes a discharge cylinder, with a connecting flange fixedly installed at the end of the discharge cylinder away from the filling body. A connection port is provided at the center of the end of the connecting flange away from the discharge cylinder. A slot is provided at the end of the discharge cylinder close to the filling body. A sealing strip is provided on the outer surface of the discharge cylinder close to the filling body.

[0007] Preferably, the cylinder, filling body, and discharge port are arranged vertically from top to bottom, and the cylinder, filling body, and discharge port are located on the same vertical line.

[0008] By using the above technical solution, and by setting the cylinder, filling body, and discharge port to be on the same vertical line, the resistance of the material during the transmission process is reduced, and the filling efficiency is improved.

[0009] Preferably, the material of the discharge cylinder is plastic, and the discharge cylinder is integrally injection molded.

[0010] By using the above technical solution and making the discharge cylinder of plastic, the generation of small metal particles can be eliminated, improving the quality of material filling. Furthermore, using plastic material can effectively reduce production costs, and the one-piece injection molding process facilitates the mass production of filling accessories, thereby improving production quality.

[0011] Preferably, the cross-section of the slot is C-shaped, and the slot is adapted to the feed inlet.

[0012] The above technical solution uses a "C"-shaped cross-section for the slot, which is adapted to the feed inlet, to facilitate the limiting of the filling accessories and ensure that the material enters the filling accessories from the feed inlet.

[0013] Preferably, the connection port gradually decreases in size from top to bottom along the axial direction, the discharge port and the connection port are connected by a thread, and the first connecting flange and the second connecting flange are fixedly connected by locking bolts.

[0014] The above technical solution ensures material transportation by setting the connection port to gradually decrease in size from top to bottom along the axial direction and connecting it with a threaded connection. At the same time, the threaded connection also facilitates the quick disassembly of the connection port and the filling accessories, making it easier for later maintenance and cleaning. Connecting flange one and connecting flange two are fixedly connected by locking bolts to ensure the strength of the filling accessories and the filling body.

[0015] Preferably, the outer diameter of the discharge cylinder is the same as the inner diameter of the filling body, and the sealing strip is provided in four identical sets, which are distributed at equal intervals on the outer surface of the discharge cylinder.

[0016] By using the above technical solution, the outer diameter of the discharge cylinder is set to be the same as the inner diameter of the filling body, ensuring that the discharge cylinder and the filling body fit tightly together and improving the overall sealing performance of the device. Furthermore, by setting four sets of sealing strips at equal intervals on the outer surface of the discharge cylinder, the sealing performance between the filling accessories and the filling body is further enhanced, preventing internal gas leakage that could reduce material filling efficiency.

[0017] Preferably, the radius of the piston is the same as the inner diameter of the filling body, and the piston extends at most above the discharge port.

[0018] By using the above technical solution, and by setting the piston radius to be the same as the inner diameter of the filling body, it can be ensured that the piston fully squeezes the material during reciprocating motion, reducing the material residue in the filling body and improving filling accuracy.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figure 1-6As shown, the present invention provides a plastic filling and discharging component for a filling machine, including a filling body 1, a cylinder 2, and a discharge port 3 located at the bottom of the filling body 1. A feed port 4 is fixedly installed on one side of the filling body 1. A filling accessory 5 is provided inside the filling body 1. A piston 6 is fixedly installed on the top of the inner wall of the filling body 1 and fixedly installed with the movable end of the cylinder 2. A connecting flange 2 7 is fixedly installed on the end of the filling body 1 near the discharge port 3. A locking bolt 8 is provided on the side of the connecting flange 2 7 away from the filling body 1.

[0031] The filling accessory 5 includes a discharge cylinder 501. A connecting flange 502 is fixedly installed at the end of the discharge cylinder 501 away from the filling body 1. A connection port 503 is provided at the center of the end of the connecting flange 502 away from the discharge cylinder 501. A slot 504 is provided at the end of the discharge cylinder 501 close to the filling body 1. A sealing strip 505 is provided on the outer surface of the discharge cylinder 501 close to the filling body 1.

[0032] Specifically, cylinder 2, filling body 1, and discharge port 3 are arranged vertically from top to bottom, and are located on the same vertical line. The advantage is that by aligning cylinder 2, filling body 1, and discharge port 3 on the same vertical line, the resistance of material during transmission is reduced, thus improving filling efficiency.

[0033] Specifically, the material of the discharge cylinder 501 is plastic, and the discharge cylinder 501 is integrally injection molded. The advantages are that by making the material of the discharge cylinder 501 plastic, the generation of small metal particles can be eliminated, improving the quality of material filling. In addition, using plastic material can effectively reduce production costs, and integral injection molding can facilitate the mass production of filling accessories 5, improving production quality.

[0034] Specifically, the slot 504 has a "C" shaped cross-section and is adapted to the feed inlet 4. The advantage is that by setting the slot 504 to a "C" shaped cross-section and adapting it to the feed inlet 4, it is easy to limit the filling accessory 5 and ensure that the material enters the filling accessory 5 from the feed inlet 4.

[0035] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0036] Specifically, the connection port 503 gradually decreases in size from top to bottom along the axial direction. The discharge port 3 is threaded to the connection port 503, and the connecting flange 1 502 and the connecting flange 2 7 are fixedly connected by locking bolts 8. The advantages are that by setting the connection port 503 to gradually decrease in size from top to bottom along the axial direction and by using a threaded connection, material transportation is ensured. At the same time, the threaded connection facilitates quick disassembly of the connection port 503 and the filling accessory 5, making subsequent maintenance and cleaning easier. The fixed connection of the connecting flange 1 502 and the connecting flange 2 7 by locking bolts 8 ensures the strength of the filling accessory 5 and the filling body 1.

[0037] Specifically, the outer diameter of the discharge cylinder 501 is the same as the inner diameter of the filling body 1, and four identical sets of sealing strips 505 are provided, which are evenly distributed on the outer surface of the discharge cylinder 501. The advantage is that by setting the outer diameter of the discharge cylinder 501 to be the same as the inner diameter of the filling body 1, a tight fit between the discharge cylinder 501 and the filling body 1 is ensured, improving the overall sealing performance of the device. Furthermore, by evenly distributing four sets of sealing strips 505 on the outer surface of the discharge cylinder 501, the sealing performance between the filling accessory 5 and the filling body 1 is further strengthened, preventing internal gas leakage that could reduce material filling efficiency.

[0038] Specifically, the radius of piston 6 is the same as the inner diameter of filling body 1, and piston 6 extends at most above the discharge port 3. The advantage is that by setting the radius of piston 6 to be the same as the inner diameter of filling body 1, it can be ensured that piston 6 fully squeezes the material during reciprocating motion, reducing material residue in filling body 1 and improving filling accuracy.

[0039] Working Principle: In use, the outer diameter of the discharge cylinder 501 is the same as the inner diameter of the filling body 1. The discharge cylinder 501 is first inserted into the filling body 1. Then, the slot 504, with a "C"-shaped cross-section, is fitted to the inlet 4 to facilitate the limiting of the filling accessory 5, ensuring that material enters the filling accessory 5 from the inlet 4. Next, the connecting flange 1 502 and connecting flange 2 7 are fixed with locking bolts 8, further strengthening the connection between the filling accessory 5 and the filling body 1. Four sets of sealing strips 505 are evenly spaced on the outer surface of the discharge cylinder 501 to further enhance the sealing between the filling accessory 5 and the filling body 1, preventing internal gas leakage that could reduce material filling efficiency. Finally, the connection port 503 is provided... The cylinder 501 gradually decreases in size from top to bottom along the axial direction and is threadedly connected to the connection port 503 to ensure material transportation. The threaded connection also facilitates quick disassembly of the connection port 503 and the filling accessory 5, making it easy for later maintenance and cleaning. The material is injected through the feed port 4, and the cylinder 2 is activated. By setting the radius of the piston 6 to be the same as the inner diameter of the filling body 1, it is ensured that the piston 6 fully squeezes the material during reciprocating motion, reducing material residue in the filling body 1 and improving filling accuracy. By setting the material of the discharge cylinder 501 to plastic, small metal particles can be eliminated, improving the quality of material filling. The use of plastic material can effectively reduce production costs, and the one-piece injection molding facilitates the mass production of the filling accessory 5 and improves production quality.
