There are also nylon and polyester as raw materials. It is made by extrusion, stretching and heat treatment. In addition to being used for sealing and bundling corrugated cardboard boxes, hot-rolled steel coils and cold-rolled steel coils, it can also be used to bundle glass, pipes, materials, water pipes, etc.

[0003] As described in the utility model patent document with the authorization announcement number CN205097517U, most of the existing strapping tape production equipment includes an extruder, a cold water tank printing machine and a winder. A stretching roller for tensioning the strapping tape can also be set between the extruder and the winder. The winder and the stretching roller are both provided with motors, and the winder and the stretching roller drive the strapping tape to move through the motor. However, in the process of printing and dyeing strapping tapes with specified text or pattern content in the strapping tape production equipment, the production parameters are usually adjusted by the staff first designing a printing roller that matches the pattern font, and after the strapping tape production is completed, the printing roller is arranged inside the printing machine, and roller printing and dyeing is performed during the strapping tape movement.

The stamp inking component 340 is fixedly installed and matched with the positioning frame 320. The surface of the movable type printing roller 330 is provided with a plurality of adjacent slots 331, and the inner side of the slots 331 is plugged with a stamp block 332. The stamp inking component 340 includes a push plate 341, a printing adhesive strip 342 and a top cylinder 343. One side of the push plate 341 is connected to the ink supply component and the other side is provided with an ink groove 344. The printing adhesive strip 342 is adhered and fixed to the inner side of the ink groove 344, and the two ends of the top cylinder 343 are respectively fixedly connected to the surface of the positioning frame 320 on one side of the push plate 341.

[0039] In this embodiment, the cold water shaping tank 100 is a water tank structure, and the cold water shaping tank 100 and the circulating liquid chamber 201 are filled with cooling liquid, and the conductive roller 120 is located below the water level of the cold water shaping tank 100 .

[0040] Specifically, the water in the cold water shaping tank 100 is used to quickly cool and solidify the softened strapping tape, thereby improving the curing effect of the printing and dyeing copy.

[0041] In this embodiment, the heat treatment roller 200 is a metal or ceramic component, one side of the Peltier sheet 220 is in contact with the inner wall of the heat treatment roller 200 , and the other side of the Peltier sheet 220 is fixedly mounted with a heat conducting fin 221 located inside the circulating liquid chamber 201 .

[0042] Specifically, the semiconductor heating principle of the Peltier film 220 is utilized to control the temperature rise of the surface of the heat treatment roller 200 on one side, and the cooling and cooling on the other side is performed to quickly cool the water inside the circulating liquid chamber 201 through the heat conducting fins 221 .

[0043] In this embodiment, the feed roller 130 and the guide roller 140 are rubber roller structures, and the surface of the driving frame 310 is threadedly sleeved with an adjusting screw having one end rotatably connected to the surface of the printing and dyeing frame 110 .

[0044] Specifically, the strapping tape is pulled under the action of the contact between the feed roller 130 and the guide roller 140 and the surface of the heat treatment roller 200, and the distance between the driving frame 310 and the printing and dyeing frame 110 is adjusted by rotating the adjusting screw to pull the strapping tape in conduction, thereby adjusting the conduction tension of the strapping tape and maintaining a certain tension to eliminate surface wrinkles.

[0045] In this embodiment, one end of the stamp block 332 is in an arc shape and the center is concentric with the center of the driving frame 310. There are a plurality of stamp blocks 332, and a portion of the stamp blocks 332 are provided with a text convex structure.

[0046] Specifically, two different stamp block 332 structures are used, and a stamp with specific text is formed on the surface of the stamp block 332 with a text convex structure to print patterns on the surface of the strapping tape. The other stamp block 332 without a text convex structure realizes the printing and dyeing blank processing on the surface of the strapping tape. Therefore, various stamp blocks 332 can be combined with each other according to different needs to produce strapping tapes with prints of different fonts, thereby reducing the replacement design cost of the printing and dyeing roller.

[0047] In this embodiment, magnetic fasteners 333 are fixedly installed on two adjacent sides of the stamp block 332, and the other two sides of the stamp block 332 are provided with slots adapted to the magnetic fasteners 333. The stamp block 332 and the movable type printing roller 330 are ferromagnetic material components.

[0048] Specifically, when the stamp blocks 332 are inserted into the slots 331 and arranged adjacent to each other, the surfaces of the adjacent stamp blocks 332 are magnetically attracted and snapped together by the magnetic buckle pieces 333 and the card slots, thereby improving the fixing effect of the stamp blocks 332 and enabling quick disassembly and assembly of the stamp blocks 332 .

[0049] In this embodiment, the adhesive strip 342 is a member made of chemical fiber or non-woven fiber material. The adhesive strip 342 is in a long strip shape and is arranged relatively parallel to the surface of the movable type printing roller 330 .

[0050] In this embodiment, the top cylinder 343 is an electric push rod structure, and the top cylinder 343 is arranged horizontally and perpendicularly to the surface of the movable type printing roller 330. The input end of the top cylinder 343 is electrically connected to the controller.

[0051] Specifically, the printing adhesive strip 342 is used to absorb the printing ink, and under the push of the top cylinder 343, it and the surface of the movable type printing roller 330 are used to squeeze the surface of the packaging belt to achieve text printing.

[0052] The freely combinable strapping belt production line font printing and dyeing processing technology includes the following steps:

[0053] S1: The extruded strapping tape is returned to a temperature of 175-185°C for softening, preferably 180°C, to facilitate printing and dyeing, maintain the conveying tension of the strapping tape, and eliminate surface wrinkles;

[0054] S2: The strapping tape is conveyed through the raised stamp structure and contacts the surface of the cotton strip with printing ink, and the strapping tape on the stamp surface is stained with ink, so that the pattern and / or text are formed and adhered to the strapping tape surface;

[0055] S3: The strapping tape with formed patterns and / or texts is quickly passed into 4-10℃ cold water for cooling, so that the softened strapping tape is cooled and shaped, thereby solidifying the surface printing and dyeing pattern and improving the text adhesion, and then collected by the winding equipment after drying.

[0056] The printing and dyeing process of the present invention has the following steps:

[0057] In the preparation stage, firstly, the required stamp blocks 332 are made according to the required pattern shape and text content and arranged and inserted into the slot 331, and the stamp block 332 without the stamp structure on the surface is inserted into the slot 331 without the text area, and the movable type printing roller 330 structure capable of processing specific text is assembled, and one end of the extruded packaging tape is guided to pass through the surfaces of the feed roller 130, the heat treatment roller 200 and the guide roller 140 in sequence, and then penetrate into the cold water setting groove 100 through the movable type printing roller 330 and the stamp inking assembly 340. The ink is then conducted by a plurality of conduction rollers 120 and then led out to the surface of the winding device through the other end of the cold water shaping tank 100. One end of the push plate 341 is connected to the ink supply structure, and the circulation pump is connected to the cold water shaping tank 100 and the passage structure of the heat treatment roller 200. The Peltier sheet 220 is turned on for preheating to keep the surface of the heat treatment roller 200 at 180±5°C. At the same time, the other side of the Peltier sheet 220 generates a refrigeration effect to cool the water inside the circulating liquid cavity 201, and the water is passed into the cold water shaping tank 100 by the circulation pump for use.

[0058] Driven by the driving structure on the surface of the printing and dyeing frame 110, the feed roller 130, the heat treatment roller 200, the guide roller 140, the stamp inking assembly 340 and the winding device synchronously rotate to conduct and pull the strapping tape to move. When passing through the surface of the heat treatment roller 200, the heat treatment roller 200 heats and softens the strapping tape and conducts the movement through the guide roller 140 and the movable type printing roller 330. The control end automatically controls the top cylinder 343 to perform intermittent movement, pushing the ink groove 344 on the surface of the push plate 341 to contact the strapping tape on the surface of the movable type printing roller 330. On the surface of the stamp block 332 with a stamp protrusion structure, the strapping tape contacts the adhesive strip 342 and is stained with ink, forming a mirror image pattern identical to the stamp structure. There is no printing and dyeing text on the surface of the strapping tape without the stamp abutting, thereby forming a specific printing and dyeing text content. After printing, the strapping tape passes through the cold water shaping tank 100 to cool down the text to solidify it, and is then pulled and collected by the subsequent drying and winding device.

[0059] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
