Description

Technical Field

[0001] This utility model relates to the field of cosmetic production equipment technology, and in particular to a blow molding device based on the modification of filling equipment. Background Technology

[0002] Cosmetic manufacturing generally includes steps such as mixing, emulsification, sterilization, blow molding, filling, and packaging. Before filling, the packaging bottles need to undergo blow molding, which involves using clean air to remove residual particles, moisture, and microorganisms from the bottle. Currently, the industry generally uses two blow molding technologies: First, manual blow molding, where operators use an air gun to blow clean the inside of each bottle. This method has a single-person efficiency of only 350-480 bottles / hour, resulting in low efficiency, large space requirements, high labor costs, and difficulty in meeting high-volume production demands. Second, using dedicated fully automated blow molding equipment. However, this dedicated equipment is expensive, has limited functionality, cannot be adapted to other production stages such as filling, and has low utilization rates.

[0003] Both manual blow molding and specialized equipment have significant limitations, and the idleness of filling equipment further exacerbates cost pressures for enterprises. This application provides a blow molding device that combines low cost, high efficiency, and reversibility by modifying idle filling equipment, meeting the core needs of cost reduction, efficiency improvement, and sustainable development in the cosmetics industry. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a blow molding device based on the modification of filling equipment is proposed to solve the problems mentioned in the background. This application modifies idle filling equipment into a blow molding device, providing a blow molding device that combines low cost, high efficiency, and reversibility.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A blow molding device based on the modification of filling equipment includes a device body. The front end of the device body is provided with multiple liftable blow needles. The upper end of each blow needle is connected to an air pressure distribution mechanism. The air pressure distribution mechanism is connected to an air pressure main pipe mechanism through a connecting valve.

[0007] As a further technical solution of this utility model: the air compressor main pipe mechanism includes an air compressor main pipe, one end of which is connected to a connecting valve, and a solenoid valve is installed on the side of the air compressor main pipe near the connecting valve.

[0008] As a further technical solution of this utility model: the connecting valve is a three-way connecting valve.

[0009] As a further technical solution of this utility model: the air pressure distribution mechanism includes a blow needle connecting pipe that is connected to the upper end of the blow needle, the other end of the blow needle connecting pipe is connected to a three-way connecting valve, two adjacent blow needle connecting pipes are connected to the same three-way connecting valve, and the three-way connecting valve is also connected to the air pressure distribution pipe.

[0010] As a further technical solution of this utility model: the end of the air compressor branch pipe that is away from the three-way connecting valve is connected to the connecting valve.

[0011] As a further technical solution of this utility model: the end of the air pressure manifold one that is away from the three-way connecting valve one is connected to the three-way connecting valve two, and the three-way connecting valve two is connected to the connecting valve through the air pressure manifold two.

[0012] As a further technical solution of this utility model: the end of the air compressor main pipe away from the connecting valve is connected to the air compressor source pipe, and a pressure regulating filter is installed on the side of the air compressor main pipe close to the air compressor source pipe.

[0013] As a further technical solution of this utility model: an air pressure regulating valve is installed on the air pressure main pipe.

[0014] As a further technical solution of this utility model: an air pressure pipe adapter is installed on the air pressure manifold.

[0015] The beneficial effects of this utility model are:

[0016] This utility model modifies idle filling equipment by removing redundant filling hoses and other accessories, and adds an air pressure distribution mechanism connected to the upper end of the blow needle. The air pressure distribution mechanism is connected to the air pressure main mechanism through a connecting valve. The air pressure main mechanism is equipped with a solenoid valve to control the bottle blowing time. High-pressure gas enters the blow needle through the air pressure main mechanism and the air pressure distribution mechanism, and the blow needle cleans the bottle. With the help of a conveyor belt, continuous semi-automatic production can be achieved.

[0017] Before the upgrade, the manual bottle blowing capacity was 350-480 bottles / hour, requiring 4 people for the same capacity. After the upgrade, the capacity is 550-750 bottles / hour, requiring only 2 people for the same capacity, saving manpower and improving efficiency.

[0018] Feasibility verification was conducted on five test samples: large-sized liquid bottles (380ml, approximately 2cm outer diameter at the mouth and 16cm high), regular liquid bottles (150ml, approximately 1.7cm outer diameter at the mouth and 10cm high), regular cream bottles (50g, approximately 5.4cm outer diameter at the mouth and 4.5cm high), small-sample emulsion bottles (25ml, approximately 1.5cm outer diameter at the mouth and 8cm high), and regular emulsion bottles (100g, approximately 2cm outer diameter at the mouth and 14cm high). No foreign matter could be expelled, meeting production requirements and achieving the cleanliness standard. Operational stability was also demonstrated; no issues such as bottle jamming or uneven airflow occurred during the test, indicating strong compatibility.

[0019] This utility model requires only minor equipment modifications, resulting in low transformation costs; the filling machine function can be restored when needed, making it a reversible modification; it optimizes existing equipment, reducing investment in new equipment; and it transforms idle equipment into a semi-automatic blow molding device, reducing costs and improving efficiency.
