Automatic toothpaste filling and sealing machines are widely used in major toothpaste and paste product production lines due to their efficient, precise and clean automation characteristics, becoming an important equipment to promote the intelligent manufacturing transformation of the daily chemical industry. In the field of daily chemical product manufacturing, toothpaste is one of the most common consumer products, and the efficiency and quality control of its production process directly affect the brand image and market competitiveness. With the continuous improvement of consumers' requirements for product appearance, sealing integrity and hygiene standards, traditional manual filling and sealing methods can no longer meet the needs of modern production.

　　1. Basic functions of automatic toothpaste filling and sealing machine

　　The automatic toothpaste filling and sealing machine is an automated equipment designed for viscous pastes such as toothpaste, ointment, and cosmetic cream. It can continuously complete the following core processes:

　　Automatic tube loading: The equipment neatly feeds the empty hose into the working turntable through mechanical or manual assistance;

　　Positioning and identification: The color mark and direction of the tube body are identified by photoelectric sensors to ensure accurate pattern alignment;

　　Automatic filling: The toothpaste is poured from the hopper into the tube body according to the set dosage, with high filling accuracy and fast speed;

　　Sealing: The tube tail is sealed by hot melting (plastic tube) or metal pressing (aluminum tube);

　　Coding and shaping: The production date and batch number are pressed at the sealing tail, and the sealing shape is symmetrical and beautiful;

　　Finished product output: The sealed toothpaste is automatically transported to the packaging line or manual inspection area.

　　2. Main components and technical highlights

　　The automatic toothpaste filling and sealing machine has a compact structure and is often composed of the following modules:

　　Paste hopper and conveying system: with heating and stirring functions to ensure the fluidity and uniformity of the paste;

　　Measuring filling system: accurately control the filling amount of each toothpaste through a servo pump, plunger pump or rotary valve system;

　　Heat sealing system: use a heated mold to seal the plastic tube and fold and press the aluminum tube;

　　Photoelectric alignment system: accurately identify the position of the hose pattern to ensure that the seal is aligned with the trademark;

　　PLC control system: set various parameters through the touch screen to achieve automatic control and fault alarm;

　　Replaceable mold system: suitable for hoses of different calibers and materials, quick and easy to replace.

　　3. Equipment advantages analysis

　　High efficiency and labor saving: an automatic toothpaste filling and sealing machine can fill 30 to 80 toothpastes per minute, which meets the needs of large-scale continuous production and significantly reduces manpower investment.

　　High filling accuracy and beautiful sealing: the advanced metering system ensures that the filling volume of each toothpaste is consistent, the sealing tail is neat and leak-proof, and the product appearance and brand image are improved.

　　Strong compatibility: It can adapt to toothpaste packaging needs of different materials (plastic hose, aluminum-plastic composite tube, metal tube) and specifications (30ml~250ml).

　　Easy operation and intelligent control: users can easily set parameters such as filling volume, sealing temperature, production speed, etc. through the human-machine interface, and monitor the operating status in real time.

　　Comply with hygiene standards: the material contact part is made of stainless steel 304/316, which meets GMP and daily chemical product hygiene standards, is easy to clean and corrosion-resistant.

　　Expandable automated production line: The equipment can be connected with labeling machines, cartoning machines, packaging machines, etc. to form a complete automated toothpaste production line.

　　In today's increasingly competitive daily chemical manufacturing, the automatic toothpaste filling and sealing machine is no longer just a tool to "improve efficiency", but also a strong support for corporate quality control, brand building and intelligent manufacturing transformation. It highly unifies filling accuracy, sealing quality and clean production standards, providing efficient and reliable packaging solutions for toothpaste and other paste products.
