Description

Box-packed edible oil stacking mechanism
Technical Field
The utility model relates to a machining production technical field, concretely relates to case dress edible oil pile up neatly mechanism.
Background
Edible oils, also known as "cooking oils", refer to animal or vegetable fats and oils used in the manufacture of food products. Is liquid at normal temperature. Due to the source of raw materials, processing technology, quality and other reasons, common edible oils are mostly vegetable oils and fats, including millet oil, peanut oil, hemp seed oil, corn oil, olive oil, camellia oil, palm oil, canola oil, sunflower oil, soybean oil, sesame oil, linseed oil, grape seed oil, walnut oil, peony seed oil and the like.
The edible oil filling machine generally adopts a flow meter type filling, wherein the flow meter type filling is that the oil conveying quantity is adjusted at any time by automatically tracking the temperature and density change of an oil product through a computer, so that the error generated along with the temperature and density change of the oil conveying quality is reduced, and the metering precision is higher. Two metering modes of constant volume filling and constant quality filling are adopted. The edible oil filling machine adopts a high-precision flowmeter and a high-precision pulse transmitter, and carries out temperature acquisition in real time to compensate density change of oil products caused by temperature difference, thereby effectively ensuring the filling and metering precision. The two metering modes of volume and mass are freely switched, and the loss caused by filling the grease in volume when the temperature is low and the density is high is overcome. The unique filling head design and the vacuum back suction system ensure that the field and the packaged finished products are prevented from being polluted by residual liquid, the filling quantity can be set at will after the filling quantity is set at a high speed and at a low speed, the filling speed is adjustable, and the bottle overflow phenomenon during the pump pressure quick filling is avoided. And power filling is adopted, and a high-level tank does not need to be assembled, so that the installation process is simplified, the production cost is reduced, and the filling efficiency is improved. The electric and gas main switch parts are matched with fine elements, so that the reliability, accuracy, stability and durability of system operation are ensured, the filling precision is high, the performance is stable, the operation and adjustment are simple and rapid, and the quality is excellent. The full-automatic liquid filling and full-automatic piston type liquid filling machine is improved and designed on the basis of the original series of filling machine products, and partial additional functions are added. The product is simpler and more convenient in the aspects of use operation, precision error, installation adjustment, equipment cleaning, maintenance and the like. The filling machine is widely applicable to various industries such as daily chemicals, grease and the like, and can be used for filling fluids with different high viscosities. The machine has compact and reasonable design, simple and beautiful appearance and convenient filling quantity adjustment. The filling process of full-automatic liquid filling includes stacking the boxes with empty bottles on a tray, conveying the boxes to a tray unloading machine through a conveying belt, unloading the trays one by one, conveying the boxes to an unloading machine along with the conveying belt, taking the empty bottles out of the boxes, conveying the empty boxes to a box washing machine through the conveying belt, cleaning the empty boxes, and conveying the empty boxes to the side of the box filling machine so as to fill the bottles with beverages into the boxes. The empty bottles taken out from the box unloader are conveyed into a bottle washer by another conveyer belt to be disinfected and cleaned, and then are conveyed into a filling machine and a cap sealing machine after being checked by a bottle checking machine and meeting the cleaning standard. The beverage is filled into bottles by a filling machine. The bottles filled with the beverage are capped and sealed by a capping machine and conveyed to a labeling machine for labeling, and the bottles are conveyed to a box filling machine to be filled into a box after being labeled, conveyed to a tray stacking machine to be stacked on a tray and conveyed to a warehouse.
The full-automatic filling machine flow: manual quantification → manual bottle placing → automatic induction of the falling of the oil nozzle at the bottle opening position → automatic filling → automatic conveying → manual cap placing → automatic cap pressing → automatic code spraying → conveyor belt storehouse. In the process of producing the edible oil, the process is developed in the direction of automation, in the last step of the edible oil, the boxed edible oil is conveyed to a warehouse through a conveyor belt, and the edible oil tank body needs to be manually stacked on a tray at a specified position in the warehouse at the tail end of the process; the manual stacking of the edible oil tank bodies on the tray from the conveying belt is a very tiring work, and a large amount of labor force is occupied; the edible oil tank body on the conveying belt is continuous, and in order to improve the efficiency better, the manual stacking mode needs to be changed, so that the labor force is liberated, the working efficiency is improved, and the labor cost is reduced.
