The thickness of the roller is more than or equal to 1 mm.

The invention relates to a method for jointing stamp sheets, which utilizes the mutual matching of an ultrasonic generator and a U-shaped joint head or a roller to complete the continuous or intermittent adhesive jointing of the required adhesive position of a roll-shaped raw material in the continuous double-layer discharging process and realize the molding production of double-layer stamp sheets with openings by corresponding cutting.

Detailed Description

The central idea of the stamp sheet joining method of the invention is as follows: the mutual matching of the ultrasonic generator and the U-shaped joint head or the roller is utilized to complete the continuous bonding and the cutting of the required bonding position and the corresponding shape in the continuous double-layer discharging process of the roll-shaped raw material, thereby realizing the high-efficiency production of the stamp sheet and meeting the processing requirement of the stamp sheet with the complex bonding shape.

The following will describe in further detail the method of joining postage stamp pieces of the present invention, taking the process of machining with rollers as an example, the specific steps include:

step 1, two reel-shaped raw material rolls are simultaneously arranged on a discharging device, the two raw material rolls simultaneously and continuously discharge materials through the discharging device, and double-layer raw materials to be jointed are formed in mutual positioning and superposition.

The double-layer raw material to be jointed is an initial raw material state which needs to be processed in the later period, the use and processing requirements of the existing roll-shaped raw material roll in the market are met, and the defect that the sheet-shaped raw material can only be processed in the previous stamp sheet jointing process is overcome.

Because the double-layer raw materials can form certain adsorption force after being superposed, the horizontal conveying can be conveniently carried out on the conveying mechanism, and convenience is provided for subsequent direct and continuous processing.

And 3, respectively matching the three sets of jointing dies above the jointing station with the ultrasonic generator below the jointing station through stroke control and positioning, and performing mutual bonding and jointing at corresponding positions in the moving process of the double-layer raw materials in the advancing process.

In this example, each set of joining mold includes a joining head and a set of moving mechanism for driving the joining head to move, and the moving mechanism can be independently driven to accurately move the joining heads under respective control, so as to realize rapid bonding joining at different positions in the process of conveying the double-layer raw materials under the cooperation of the ultrasonic generator. Such as: according to the jointing requirement, three sets of jointing dies can be distributed in parallel and are matched with the ultrasonic generator all the time, so that a continuous and linear type adhering interface is formed; for another example: one of the joint heads is in reciprocating fit with the ultrasonic generator through the pulse control of the moving mechanism, so that an intermittent interface is formed; for another example: the moving mechanism controls the joint head to move according to a set line, and meanwhile, the joint head is matched with the ultrasonic generator in the moving process, so that a bonding interface in a required shape is formed on the double-layer raw material, and the joint processing of the stamp piece in a special shape is completed.

As the jointing process is continuously carried out in the conveying process of the double-layer raw materials, the jointing head in the embodiment adopts a copper roller, the diameter of the roller is 4cm, the thickness of the roller is 2mm, the wheel surface of the roller corresponds to the ultrasonic generator, and the roller is connected with the moving mechanism. The width of the interface is determined by the thickness of the roller, and the width of the interface is 2mm due to the thickness of the roller of 2 mm. The friction between the roller and the surface of the double-layer raw material in the conveying process is reduced through rotation, the processing quality is ensured, the processing efficiency is improved, and meanwhile, higher processing speed can be borne.

And 4, conveying the jointed double-layer raw materials to a cutting station through a conveying mechanism, and cutting the jointed double-layer raw materials by a cutter to form the final required double-layer stamp piece with an opening.

In general, the cutting knife includes a transverse cutting knife and a longitudinal cutting knife, and the cutting of the finished stamp piece is completed through the mutual matching of the transverse cutting knife and the longitudinal cutting knife. Or the cutter can also comprise a special-shaped cutter, and the stamp sheet with the special shape can be accurately cut by the special-shaped cutter so as to meet the actual use requirement.

The finished stamp sheet is cut into a double-layer structure, one side or a plurality of sides of the stamp sheet are provided with openings, the rest sides are mutually bonded to form interfaces, and stamps or other paper collections can be directly placed into the interlayer of the double-layer stamp sheet, so that the protection of the collections is formed.

Of course, the above-mentioned process is only one specific implementation example, and the bonding head in the above-mentioned process can also be a bonding head whose cross section is in the shape of 'U', and the arc bottom surface of the 'U' bonding head is correspondent to the ultrasonic generator, and by means of the contact of the arc bottom surface and the surface of the double-layer raw material, it can reduce friction and cost of the bonding head. In order to improve the aesthetic property of the interface, the thickness of the arc-shaped bottom surface of the 'U' -shaped joint head is more than or equal to 1mm, and the thickness is the width of the interface which can be processed. The U-shaped joint has limited machining speed, low cost and convenient maintenance and can meet the machining requirement of common products.
