Description

Technical Field

[0001] The invention relates to the technical field of liquid packaging equipment, in particular to a clamping and pulling type liquid packaging machine. Background Art

[0002] Liquid packaging machines are used for bagging and packaging of liquid and sauce products in the food industry, pharmaceutical industry, and daily chemical industry, such as jelly, ketchup, honey, jam, chocolate sauce, juice, chili sauce, soy sauce, sesame oil, mouthwash, shampoo, shower gel, etc. Existing liquid packaging machines mainly use volumetric filling systems, spout bag filling and bag-feeding packaging for packaging, usually including filling mechanisms, liquid storage barrels, control systems and conveyor belts.

[0003] When a liquid packaging machine that uses a spout bag filling method is packaging some relatively viscous liquid products, during the sealing or shearing process, due to the viscosity and elasticity of the liquid, the liquid itself will show a filamentary adhesion phenomenon, which is called wire drawing. At the same time, insufficient retraction distance or slow retraction speed of the equipment will increase the wire drawing phenomenon, which will lead to unsightly packaging, loose sealing, product leakage and other problems. The wire drawing phenomenon may also affect the filling accuracy, resulting in the actual filling volume not being consistent with the set value, thereby affecting product quality.

Subsequently, the two cutting cylinders 1009 are activated to drive the cutting knife 1010 arranged in the groove 506 of the movable pressing plate 1006 to eject, and the interconnected packaging bags are divided into single packaged products. The divided single packaging bags fall onto the conveyor belt 12 through the arc-shaped discharge chute 1011 and are then transported out through the conveyor belt 12, thus completing one operation.

[0063] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
