Detailed Description

The following is a specific embodiment of the present invention, and the technical solution of the present invention is further described with reference to the accompanying drawings, but the present invention is not limited to these examples.

Example 1

The packing machine of the present invention comprises a transporting device for transporting nuts, a weighing and blanking device for weighing nuts and pouring nuts satisfying weighing conditions into a packing bag, a packing paper forming device for preparing packing paper into a packing paper tube, a sealing device for sealing the packing paper tube into continuous packing bags, and a cutting device for cutting the continuous packing bags into individual packing bags, as in the conventional nut packing machine, thereby completing the whole packing process.

The conveying device in the embodiment is a chain bucket elevator with a Z-shaped channel, and the weighing and blanking device is a multi-head scale. Before packaging, the nuts need to be lifted from the bottom of the packaging machine to a hopper of a multi-head scale arranged at the top of the packaging machine through a Z-shaped channel by using a chain bucket lifting machine, the nuts fall on a charging tray after passing through the hopper, the charging tray corresponds to a plurality of scales, the scales are uniformly distributed on the plane of the charging tray, the nuts are scattered freely by vibration of the charging tray and are scattered into the scales of the multi-head scale, the multi-head scale starts to weigh the nuts in the scales, when the mass addition of the nuts in the scales of any combination reaches a set value, the bottoms of the corresponding scales of the combination are opened or turned over, so that the nuts fall into a packaging bag with the bottom sealed below and the top open, and then the top of the packaging bag is sealed to form a product.

Therefore, before blanking, the wrapping paper needs to be formed and prepared, firstly, since the wrapping paper is a wrapped paper roll before forming and is in a sheet shape after unreeling, a first heat sealing piece needs to be arranged to connect two sides of the wrapping paper to form the paper tube 10.

The paper tube 10 then needs to be prepared as a specially shaped formed paper tube, as shown in fig. 1 and 2, and the wrapper forming device includes a die 20 and a forming guide 30. The mold 20 is in the shape of a four-corner star, which includes at least four arcuate sides 21 each recessed toward the middle portion of the mold 20, and defines a molding corner 22 at the junction of adjacent arcuate sides 21, thereby obtaining four molding corners 22. The forming guide 30 is provided at the forming angle 22, and the wrapping paper prepared as the paper tube 10 is fitted around the die 20, thereby preparing a formed paper tube having a cross section conforming to the shape of the die 20, four sealing angles, and a hollow center to form a blanking passage.

In the present embodiment, the molded article guides 30 are provided as rollers provided on both sides of the molding angle 22, respectively, which can guide the molded paper tube 10 to move down so that the upper portion of the paper tube 10 that is not molded is molded through the mold, in addition to pinching the edge of the paper tube 10 to a sealing angle.

In addition, in order to help the paper tube 10 to better fit the mold 20 to prepare it in the shape of the mold 20, a fitting member for fitting the paper tube to the arcuate edge 21 is also provided. In this embodiment, the attaching member is a rubber coating wheel 24 disposed outside the arc edge 21, and when the paper tube 10 passes between the rubber coating wheel 24 and the outer surface of the mold 20, the rotating rubber coating wheel 24 attaches the paper tube 10 to the outer surface of the mold 10, so that the sealing angle is easier to form.

After the paper tube 10 is prepared as a forming paper tube, and before the nuts are put into the forming paper tube, the bottom of the forming paper tube needs to be sealed, and the sealing of the forming paper tube has two steps: the four sealing corners are first sealed with the second heat-seal member 40 provided at the outlet end of the die 20, respectively, and as shown in fig. 3, the second heat-seal member 40 may be a heat nip plate provided at both sides of the forming corner 22, and when the paper tube 10 is clamped with the sealing corner by the forming guide 30 and is ready to be separated from the die 20, the sealing corner is heat-sealed with the heat nip plate. After the sealing angle is heat-sealed, the opening of the blanking passage is sealed, and thus a third heat-seal member for sealing the passage opening of the blanking passage is provided at the outlet side of the second heat-seal member 40, thereby sealing the bottom of the formed paper tube orderly and completely.

At this time, nuts are further put into the semi-sealed paper tube, and since the upper paper tube is still formed into the paper tube by the wrapping paper forming device, a blanking through hole 23 is formed in the middle of the die 20 to facilitate the putting of nuts into the semi-sealed paper tube. After a certain amount of nuts are put into, the waist of the formed paper tube is sealed, so that the formed paper tube between the bottom and the waist forms a complete package, and meanwhile, the sealing width of the waist can be increased, so that the top of the packaging bag is sealed, the bottom of the next packaging bag is sealed, a continuous packaging bag strip is formed, the sealing times are reduced, and finally, the packaging bag can be cut by a cutting device to form an independent packaging bag.

Example 2

The structure of this embodiment is substantially the same as that of embodiment 1, and differs only in the structure of the attaching member, and the structural similarities thereof will not be described in detail.

In this embodiment, the laminating piece is the friction strip that sets up in arc limit 21, and the friction strip can adsorb paper tube 10 laminating in the arc limit after arc limit 21 rubs and produces static to help the sealed angle of paper tube 10 shaping better.

The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
