Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a liquid filling machine. Background Art

[0002] With the development of mechanical automation, many production steps in traditional production processes are gradually replaced by automated machinery, which not only greatly improves production efficiency, but also saves a lot of labor costs. Filling machines are a small category of packaging machines. From the type of packaging materials, they can be divided into liquid filling machines, paste filling machines, powder filling machines and granule filling machines. From the degree of production automation, they can be divided into semi-automatic filling machines and fully automatic filling production lines.

[0003] Dairy products are healthy foods with high nutritional value. Milk protein is easily digestible and easily absorbed by the human body. With the continuous advancement of production technology, there are many types of dairy products at present. Among them, yogurt is a milk product made from milk by adding a fermentation agent to the milk. It not only retains all the advantages of milk, but also is easier to digest than milk. Yogurt is gradually accepted by more and more people, and the types and specifications of yogurt are becoming more and more diverse. With the improvement of people's living standards, more and more people choose to order yogurt from fresh milk stations, and different families have different choices. However, most of the existing yogurt filling equipment can only fill one specification of yogurt. For fresh milk stations, purchasing such filling equipment is of poor practicality, high cost, and low filling efficiency.

[0004] The patent with application number CN202220552314.2 discloses a filling device for yogurt production, whose structure includes a filling mechanism and a sealing mechanism. The filling mechanism is arranged at the bottom of the first mounting plate, and the second mounting plate and the oblique spray gun and other components are driven by the first electric push cylinder to adjust the height, and the yogurt is diverted by the metering valve and the feeding pump. At this time, the diversion hose is heated by the electric heating cylinder to increase the flow speed of the yogurt inside it. The sealing mechanism is arranged at the bottom of the first mounting plate, and the winding assembly and the torsion spring cylinder drive the capping film to move to an appropriate height through the adjustment effect of the third electric push cylinder and the fourth electric push cylinder, and then the third electric push cylinder and the fourth electric push cylinder are mutually reversely controlled, so that the winding assembly and the torsion spring cylinder drive the capping film to contact the capping knife block and the top of the filling box at the same time.

[0005] However, this patent can only fill yogurt of one size at a time, and cannot solve the problems of poor practicality and low filling efficiency in the above background.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0021] like Figures 1 to 3As shown, the utility model liquid filling machine comprises: an operating table 1, a conveyor belt 2, and along the moving direction of the conveyor belt 2 are arranged in sequence: a box body delivery mechanism 3 for delivering the box body, a filling mechanism 4 for filling the box body with liquid, and a cover delivery mechanism 5 for delivering the cover body onto the box body; a push plate 22 for pushing the box body to move is installed on the conveyor belt 2, the conveyor belt 2 is chain-driven, the conveyor belt moves along the operating table 1, the push plate 22 is fixedly connected to the transmission chain 21 of the conveyor belt 2, and the conveyor belt drives the push plate 22 to move along the operating table 1; a continuous cavity 251 for accommodating boxes of different specifications is provided on the push plate 22, and the inner diameter of the cavity 251 of the continuous cavity is larger than the cavity The inner diameter of the second cavity 252, the cavity one 251 is used to clamp the large-sized box body, and the cavity two 252 is used to clamp the small-sized box body. The movement of the push plate 22 will drive the box body to move along the movement direction of the conveyor belt 2; the box body delivery mechanism 3 is composed of a box body positioning plate and a box body blanking rod 31. The box body positioning plate can limit the specifications of the box body that can be delivered, and at the same time, it can fix the position of the box body blanking rod 31 to provide a channel for delivering the box body; the cover body delivery mechanism 5 is composed of a cover body positioning plate and a cover body blanking rod 51. The cover body positioning plate can limit the specifications of the cover body that can be delivered, and at the same time, it can fix the position of the cover body blanking rod 51 to provide a channel for delivering the cover body.

[0022] The box body positioning plate includes a box body positioning plate 1 32 and a box body positioning plate 2 33; both the box body positioning plate 1 32 and the box body positioning plate 2 33 are provided with through holes for facilitating the passage of the box body, and the inner diameter of the box body positioning plate 1 32 is larger than the inner diameter of the box body positioning plate 2 33, providing channels of different sizes for the placement of boxes of different specifications, so that boxes of different specifications can pass through.

[0023] The filling mechanism 4 includes a filler and a mounting frame; the mounting frame is fixedly mounted on the operating table 1; and the filler is fixedly mounted on the mounting frame.

[0024] The cover positioning plate includes a cover positioning plate 1 52 and a cover positioning plate 2 53; both the cover positioning plate 1 52 and the cover positioning plate 2 53 are provided with through holes for facilitating the passage of the cover, and the inner diameter of the cover positioning plate 1 52 is larger than the inner diameter of the cover positioning plate 2 53, providing channels of different sizes for the placement of covers of different specifications, so that covers of different specifications can pass through.

[0025] Since cavity one 251 and cavity two 252 on the push plate 22 are continuous, and cavity two 252 is smaller than cavity one 251, when the push plate 22 drives the box body to move, the small-sized box body lags behind the large-sized box body; the box body positioning plate one 32 and the box body positioning plate two 33 are respectively arranged in sequence along the moving direction of the conveyor belt 2, and the cover body positioning plate two 53 and the cover body positioning plate one 52 are respectively arranged in sequence along the moving direction of the conveyor belt 2, so as to put the cover body for the box body of corresponding size.

[0026] The cover body delivery mechanism 5 and the box body delivery mechanism 3 of the liquid filling machine of the utility model can deliver covers and boxes of different specifications respectively, and the push plate 22 can determine the position of the box body while driving it to move, so that it is in the same straight line, thereby achieving the effect of filling boxes of different specifications at the same time, having high practicality and improving the filling efficiency.

[0027] Working principle:

[0028] The staff uses the box delivery mechanism 3 to deliver boxes of different specifications according to demand, and then uses the push plate 25 to push the box, so that the box is positioned while moving along the conveyor belt 2, so that the box is in the same straight line position, and then the filling mechanism 4 fills the yogurt, and then the cover delivery mechanism 5 delivers the cover on top of the matching box to complete the filling.
