Technical Field

The invention particularly relates to a processing technology for the bottom of a paper cup and a paper bowl.

Background

The paper cup paper bowl of prior art is in production shaping manufacturing process, and its bottom material all cuts into banding paper in advance and puts up the board in whole book, send the mould to carry out the contour machining through the single die-cut shaping of board, and its bottom is generally circular, and during die-cut, realize circular punching press in proper order on the banding paper, and circular periphery has the waste material at four angles, causes more waste. Since the die cutting is performed in one part, the machine is complicated in structure, and paper jamming may occur due to paper scraps or the like. And the strip paper is all the whole roll, uses up the back, needs to shut down the change, influences production efficiency, and the cup body is generally processed through cross cutting machine moreover, and the bottom is because need cut, so need the cutting machine to operate, and equipment cost is great. Paper cup paper bowl trade belongs to the food packaging industry, generally requires the dust-free workshop to produce, and the dustless workshop management is not convenient for to die-cut industrial waste material and the dust that produces.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: in order to overcome the defects of the prior art, a paper cup and paper bowl bottom processing technology is provided.

The technical scheme adopted by the invention for solving the technical problems is as follows: a processing technology for the bottom of a paper cup and a paper bowl comprises the following steps:

1) typesetting: typesetting on the whole roll of material, wherein each bottom is circular, and the two adjacent circular bottoms are staggered and tangent;

2) printing: printing a target pattern on the circular base;

3) die cutting: and cutting the formed circular bottom into single circular bottoms by a die cutting machine.

4) Pre-pressing: pre-pressing and forming by a forming machine, and conveying to a forming die for processing, wherein during forming, film coating operation can also be carried out;

5) bonding: the cup body is conveyed into a grinding tool through a feeding frame, a suction nozzle, a claw and a stepping motor to be subjected to bottom forming processing, and the adhesion of the cup body and the bottom is completed.

Preferably, in step 4), the material of the coating is a waterproof material.

The bottom processing technology for the paper cup and paper bowl has the advantages that the bottom prefabricating method is adopted, so that the combination of the cup body and the bottom can be finished through the die cutting machine, the consistency of equipment is improved, the splitting machine is eliminated, the fixed asset cost is saved, the phenomenon of paper jam can be reduced by prefabricating the circular bottom, discontinuous machine halt and paper replacement caused by the use of the whole roll of strip paper can be reduced, the working efficiency is improved, the prefabrication of the circular bottom can be used for better typesetting, the waste of raw materials is reduced, the printing can be carried out in advance, the printing quality is ensured, and the die cutting and the forming machine are separated, so that the management of dust in dust-free workshops can be facilitated.

Detailed Description

The first embodiment is as follows:

a processing technology for the bottom of a paper cup and a paper bowl comprises the following steps:

1) typesetting: typesetting on the whole roll of material, wherein each bottom is circular, and the two adjacent circular bottoms are staggered and tangent;

through typesetting, the circular bottoms are mutually staggered and tangent, and compared with the prior art that the circular bottoms are distributed in a strip shape, the waste of paper can be reduced. In fact, other shapes may be optimized to reduce waste by typesetting.

2) Printing: printing a target pattern on the circular base;

the printing in the prior art is finished on strip paper, and the pattern deviation can occur when the printing is matched with a paper pushing mode of an existing forming machine (the contradiction between stencil printing and equidistant pushing). And the printing is carried out on the bottom of the whole plate, and the whole plate die cutting technology has no offset. And the waterproof material can be accurately printed on the bottom of the container, and all the parts need to be pasted to improve the waterproof performance.

4) Die cutting: cutting the molded circular bottom into a single circular bottom by a die cutting machine; the bottom forming and cutting can be completed through the die cutting machine, the existing process needs to be realized through the die cutting machine, the consistency of equipment is improved, the equipment cost is reduced, namely, the production cost is reduced, and the company competitiveness is improved.

2) Pre-pressing: pre-pressing and forming by a forming machine, and conveying to a forming die for processing, wherein during forming, film coating operation can also be carried out;

when the make-up machine carries out the pre-compaction, can carry out the tectorial membrane operation to circular bottom, be about to the coating material pressure attach on two surfaces, promote bottom feel, also can adopt the water proof membrane, and then promote bottom waterproof performance.

5) Bonding: the cup body is conveyed into a grinding tool through a feeding frame, a suction nozzle, a claw and a stepping motor to be subjected to bottom forming processing, and the adhesion of the cup body and the bottom is completed.

Preferably, in step 4), the material of the coating is a waterproof material.

Moreover, by adopting the process of the scheme, the punching and forming machine is separated, the dust generation source of a forming workshop can be reduced, and the working environment of the dust-free workshop is improved. The temporary waste placing tool and space of the forming workshop are saved, and the space utilization rate of the forming workshop is improved.

Moreover, the plastic-free paper cup in the prior art is processed by adopting a coating process, and because the in-line technology is not mature enough, when the coating is thick, the paper product needs to be bent and molded in the production process, and the surface is easy to crack; when the coating is thin, the water resistance of the joint is also deteriorated. By adopting the process, the thickness of the coating can be adjusted according to the waterproof requirement at the joint part of the cup bottom material (a layer of waterproof material is added by printing so as to improve the overall waterproof effect.

Compared with the prior art, this paper cup paper bowl bottom processing technology adopts the prefabricated method in bottom, make the cup body also can accomplish through the cross cutting machine when combining with the bottom, promoted the uniformity of equipment, saved manufacturing cost, through prefabricated circular bottom, can reduce the card paper phenomenon, and also can reduce because the use of whole book of strip paper brings the discontinuity shut down and trade paper, the work efficiency is improved, and the prefabrication of circular bottom can carry out better typesetting, reduce the waste of raw and other materials, also can print in advance, guarantee product quality. The punching and the forming are separated, so that the equipment is simplified, and the workshop management is facilitated. And the elimination of a splitting machine saves the equipment cost and the production space of a company. The production process is adjusted to be more suitable for the popularization of the production of plastic-free environment-friendly paper cups, paper bowls and new products.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
