Description

A food packaging forming method

Technical Field

The invention relates to a method for food packaging, in particular to a method for food packaging forming.

Background technique

Food packaging is a component of food commodities. It is one of the main projects in the food industry process. It protects food and prevents it from being damaged by biological, chemical, and physical external factors during the circulation process from leaving the factory to the hands of consumers. It can also have the function of maintaining the stable quality of the food itself. It is convenient for food consumption and is the first to show the appearance of food and attract consumers. It has value beyond material cost. Therefore, the food packaging process is also an inseparable part of the food manufacturing system engineering.

There are many forms of food packaging, such as cans, bags, boxes, bottles, wraps, etc. The shapes of the packages are strips, triangles, circles, ovals, squares, etc. Since wrapping is wrapping the wrapping paper directly on the food, the shape of the packaged food is mainly determined by the shape of the food itself.

In the field of candy packaging, wrapping is a common method for packaging candies, and is used in the packaging of various hard candies, soft candies, and chocolates.

There are also many machines that use wrapping to package food, but these machines have the following defects when packaging food:

Since the shape of the packaged food is mainly determined by the shape of the packaged food itself. During packaging, the food presses the wrapping paper into the former for molding. Since the former does not move, after the wrapping paper is pressed into the former, the shape of the packaged food will be completely attached to the food. Therefore, the packaged shape will be consistent with the food. In this way, if the food itself is poorly molded, the shape of the packaged finished product will also be poorly molded. For example, if the round food itself is not round enough, or there are uneven problems on the surface, the shape of the packaged finished product will not be round enough, or there will be uneven defects on the surface. The shape of the packaged food is single, and there is no shape and structure decoration on the outer packaging. The appearance is not beautiful and the feel is poor.

Summary of the invention

In view of the above-mentioned defects of the existing food packaging methods, the present invention provides a food packaging molding method, which can not only realize the packaging of food, but also even if the food itself is poorly molded, the appearance of the packaged finished product will not be affected, and the beauty of the packaged finished product will not be affected. In addition, patterns can be formed on the outer surface of the finished product, which feels better.

In order to solve the above technical problems, the technical solution adopted by the present invention is:

A food packaging and forming method, characterized in that: an oscillator is installed on a packaging machine, a support frame is installed on the oscillator, and a former is installed on the support frame. During packaging, the food moves toward the former, and the packaging paper is pressed into the former. The oscillator oscillates, driving the support frame to oscillate in the direction of the food movement, thereby driving the former to move in the direction of the food movement. After packaging is completed, the oscillator oscillates, driving the support frame to oscillate in the opposite direction of the food movement, thereby driving the former to oscillate in the opposite direction of the food movement, and the packaged food is discharged from the former.

The former comprises a body, a forming groove is arranged on the body, and a flexible material ring is installed in the forming groove.

The flexible material ring is preferably a rubber ring.

The support frame includes an oscillator mounting part, an arc portion and a former mounting part, one end of the arc portion is connected to the oscillator mounting part, and the other end is connected to the former mounting part, the oscillator is mounted on the oscillator mounting part, and the former is mounted on the former mounting part.

The arc-shaped portion is made of elastic material.

The elastic material is a spring sheet.

The oscillator is a linear oscillator.

The above-mentioned food packaging former is mainly used for packaging and forming round, quasi-round, oval or quasi-oval foods, such as round candies, round chocolates and the like.

Compared with the prior art, the present invention has the following beneficial effects:

1. The present invention installs an oscillator on the packaging machine, a support frame on the oscillator, and a former on the support frame. During packaging, the food moves toward the former, and the packaging paper is pressed into the former. The oscillator oscillates, driving the support frame to oscillate in the direction of the food movement, thereby driving the former to move in the direction of the food movement. After packaging is completed, the oscillator oscillates, driving the support frame to oscillate in the opposite direction of the food movement, thereby driving the former to oscillate in the opposite direction of the food movement, and the packaged food is discharged from the former. Since the present invention installs an oscillator on the packaging machine to drive the former to oscillate, during food packaging, the food presses the packaging paper into the former. When the packaging paper contacts the former, the oscillator drives the former to move in the direction of the food movement, which provides a buffer for the food packaging and molding, so that the food packaging paper contacts the former in a soft contact rather than a hard contact. In this way, after the packaging paper is formed in the former, it will not be close to the food. In this way, even if the food molding quality is poor, the molding quality of the packaged food will not change with the change of the shape of the food, and the appearance after the packaging molding will not be affected. In addition, due to this buffering effect, the packaged food is not easy to be crushed. When the oscillator oscillates up and down, the wrapping paper contacts the former. After the packaging is completed, lines and patterns will be formed on the finished packaging product, making the appearance more beautiful, the three-dimensional sense stronger, and the feel better.

The former of the present invention comprises a body, a forming groove is arranged on the body, and a flexible material ring is installed in the forming groove. The flexible material ring plays a buffering role, can prevent the packaging paper from hard contact with the forming groove, plays a buffering role, makes the appearance of the packaged product less likely to be affected, and can also provide a good protection for the packaged food.

The support frame of the present invention includes an oscillator mounting portion, an arc portion and a former mounting portion, one end of the arc portion is connected to the oscillator mounting portion, and the other end is connected to the former mounting portion, the oscillator is mounted on the oscillator mounting portion, and the former is mounted on the former mounting portion. The arc portion is made of elastic material. Since the arc portion is made of elastic material, the elastic material enables the former to shake up and down when oscillating up and down, so that the packaging paper enters the molding groove when it is impacted by the food. After contacting the molding groove, the former will move forward due to the elastic material, avoiding hard contact between the packaging paper and the former. It further plays a buffering role.
