Description

Method for producing jigsaw puzzle without connecting points

Technical Field

The invention relates to a manufacturing method, in particular to a method for quickly producing a jigsaw puzzle without connecting points, and belongs to the field of printing.

Background

The jigsaw is a common educational toy for children, and is manufactured by firstly printing patterns on a paperboard in an integral printing mode and then carrying out die cutting in a die cutting mode to form a piece of jigsaw. Because the jigsaw needs to be guaranteed to be accurate in quantity before being packaged and cannot lack blocks or multiple blocks, connecting points need to be designed during die cutting, all the jigsaws can not be completely separated after die cutting, a complete jigsaw can be clearly seen under the condition that the connecting points are simply connected, the number of the jigsaw blocks before being packaged and the completeness of patterns are checked, and the production process is facilitated.

The above production process brings about the following results: there is more than one tie point interconnect between a cubic picture arragement, need break the tie point during the use to cause the border unevenness of every cubic picture arragement, can produce certain extrusion or deformation each other during the concatenation pattern, influence final picture arragement effect, simultaneously, the process of breaking of tie point still can produce more tiny paper foam, and sanitary conditions is poor, easily causes pruritus or allergy, is unfavorable for less child's use.

To solve the above problems, it is a main problem to be solved by the present invention to design a method for producing a jigsaw puzzle without connecting points.

Disclosure of Invention

In view of the above-mentioned existing circumstances, the present invention aims to provide a method for producing a jigsaw puzzle without connecting points, so as to eliminate the problems caused by the connecting points in later use and meet the use requirements of environmental protection, sanitation and safety.

In the existing printing and binding industry, a die cutting machine mainly comprises a tiger machine with a side opening and a flat press with a flat opening, and is influenced by the closing and opening actions of die cutting, when a cutter is lifted, the cut block jigsaw can be taken up by inertia, the whole jigsaw is disordered, and the number of blocks of the later jigsaw cannot be controlled. Under the condition of having connection points, the connection points can effectively prevent the block jigsaw from being taken up, and ensure the complete visibility of the jigsaw, and under the condition of no connection points, a corresponding structure is required to be designed to ensure the completeness of the jigsaw after die cutting. Therefore, the invention is realized by adopting the following technical scheme:

a method for producing a jigsaw puzzle without connecting points comprises the following specific steps:

step 1, sticking the bleeding edge of the printed picture on the white cardboard serving as a bottom support, and keeping the positions of the picture and the white cardboard fixed.

And 2, putting the bonded white cardboard and the spliced picture into a die cutting machine, and performing integral full-through die cutting on the spliced picture while completing semi-transparent die cutting on the white cardboard.

And 3, taking the die-cut white cardboard and the picture pieces out of the die-cutting machine, tearing off bleeding edges of the picture pieces from the surface of the white cardboard, and keeping the picture pieces complete and on the white cardboard.

And 4, horizontally sending the spliced picture into a package, and finishing the production of the finished product jigsaw without connecting points.

The pasting in the step 1 is local pasting.

The sticking position is positioned at the corner of the bleeding edge.

The white cardboard is more than 150 g.

The method for producing the jigsaw puzzle without the connecting points has the advantages that:

1. the white cardboard is used as the bottom support to support the picture puzzle in the die cutting process, so that the whole movement of the die-cut massive picture puzzle is facilitated, the process of taking the die-cut massive picture puzzle out of the die cutting machine is simplified, the die-cut massive picture puzzle is particularly convenient to take out of a slot machine with an opening on the inclined side, and the white cardboard is good in applicability, high in die cutting speed and high in processing efficiency;

2. the die-cutting process of the spliced picture and the white card paper as the bottom support are integrated through mutual adhesion of the spliced bleeding edge and the white card paper, the existing bleeding edge is utilized to form a fastening effect on the cut block jigsaw puzzle, the scattering phenomenon of the block jigsaw puzzle after die cutting is avoided, the dependence of the prior process on a connection point between the block jigsaw puzzles is eliminated, the produced block jigsaw puzzle has smooth and flat edges, paper foam cannot be generated in use, pollution, pruritus and even allergy can not be generated due to the paper foam, and the environmental protection and the safety of products are greatly improved;

3. the production mode is simple and convenient, can be matched with the existing die-cutting machine for use, and has good applicability and flexible use.

Detailed Description

The method for producing a puzzle without a connecting point according to the present invention is described in further detail below with reference to FIG. 1:

the invention discloses a method for producing a jigsaw puzzle without connecting points, which comprises the following specific steps:

step 1, sticking four corners of the printed picture-puzzle bleeding edge on a white cardboard serving as a bottom support in a local bonding mode, and keeping the positions of the picture-puzzle and the white cardboard fixed.

In this example, the bottom support 2 is made of 150 g of white cardboard, which has a certain bearing capacity and a certain thickness, so that the subsequent semi-permeable die-cutting process can be effectively completed. Four corners of the bleeding edge 4 in the picture mosaic 1 are locally bonded in a dispensing manner, so that the printed picture mosaic 1 and the white cardboard 2 form a whole, and meanwhile, the local bonding can also facilitate tearing and separation of the bleeding edge 4 in the later period.

Of course, the sticking position can also be the edge of the bleeding edge 4 or the edge and the corner part which are stuck together, and the sticking position can be wholly stuck or partially stuck as long as the relative fixation and stability of the two positions can be ensured.

The die cutting process can realize the full-transparent die cutting of each block jigsaw puzzle at one time, and the cutter can also perform the semi-transparent die cutting on the white card paper 2 at the same time, so that the complete die cutting separation of the bottom surface of the jigsaw 1 is ensured, the die cutting quality of each block jigsaw puzzle is ensured, meanwhile, the whole full-transparent die cutting is performed on the jigsaw 1, a connection point required by the prior art can not be formed, and after the connection point of interaction does not exist between each block jigsaw puzzle, the edge of each block jigsaw puzzle is flat, smooth, safe and environment-friendly.

After die cutting, the block jigsaw is kept in a mutually spliced state and is limited by the bleeding edge 4, when the cutter is lifted, the block jigsaw after die cutting cannot be taken up under the action of inertia force of the cutter, the occurrence that the integrity of the jigsaw is damaged before a finished product is packaged and possibly generated in a state without a connecting point is avoided, and the dependence on the connecting point is eliminated. The restriction of the peripheral bleeding edge 4 ensures that the block puzzle does not scatter.

The die cutting machine comprises a tiger machine with a side opening and a flat press with a flat opening, and no matter the white cardboard 2 and the picture arrangement 1 are taken out from the inclined side or the flat side, the die-cut block picture arrangement can always keep complete patterns under the protection of the frame-shaped bleeding edge 4. When the bleeding edge 4 of the picture mosaic 1 is torn off from the white cardboard 2, the picture mosaic can still be kept in a complete state under the action of mutual nesting force, thereby providing help for checking the number of the block-shaped picture mosaics and accurately packaging the picture mosaic in the later period.

The completely spliced picture can be directly and horizontally sent to a packing box to finish the manufacture of the finished product jigsaw without connecting points. Or the spliced picture is directly and horizontally sent into the sealing bag for fixation, can still be kept complete under the action of the sealing bag, and then is packaged subsequently, so that the finished picture mosaic can continuously present a complete state in the packaging box.
