Description

Technical Field

[0001] The present invention relates to the technical field of BOPP film printing, and specifically to a high-temperature resistant BOPP film printing mechanism. Background Art

[0002] BOPP film is a biaxially oriented polypropylene film. The production of BOPP film is to first make the melt of high molecular weight polypropylene into a sheet or thick film through a long and narrow die head, and then in a special stretching machine, at a certain temperature and a set speed, stretch simultaneously or step by step in two perpendicular directions, and through appropriate cooling or heat treatment or special processing to make the film. Commonly used BOPP films include: ordinary biaxially oriented polypropylene film, heat-sealable biaxially oriented polypropylene film, cigarette packaging film, biaxially oriented polypropylene pearlescent film, biaxially oriented polypropylene metallized film, matte film, etc. BOPP film also has deficiencies, such as being prone to accumulating static electricity and having no heat-sealability. On a high-speed production line, BOPP film is prone to generating static electricity, and an electrostatic eliminator needs to be installed. In order to obtain a heat-sealable BOPP film, a heat-sealable resin solution such as PVDC latex, EVA latex, etc. can be coated after corona treatment on the surface of the BOPP film, or a solvent-based adhesive can also be coated, or an extrusion coating or coextrusion compounding method can be used to produce a heat-sealable BOPP film. This film is widely used in the packaging of bread, clothes, shoes and socks, etc., as well as the cover packaging of cigarettes and books. The initiation tear strength of BOPP film increases after stretching, but the secondary tear strength is very low. Therefore, no cuts can be left on both ends of the BOPP film, otherwise the BOPP film is prone to being torn during printing and lamination. After BOPP is coated with self-adhesive, it can produce sealing tapes, which is a market with a large consumption of BOPP. BOPP film usually needs to be printed during production.

[0003] For example, the patent document with the publication number CN 213675979 U discloses a high-temperature resistant BOPP film printing device, which relates to the technical field of BOPP film printing. Aiming at the problem of poor working performance of the existing high-temperature resistant BOPP film printing device, the following solution is proposed. It includes a base, and vertical mounting plates are fixed at the four corners of the top of the base. A horizontally arranged rotating shaft is rotatably connected through bearings on the opposite sides of the two mountings. A horizontally arranged winding drum is provided between the two rotating shafts. Connecting mechanisms are provided at both ends of the winding drum. The winding drum is fixed at the opposite ends of the two rotating shafts through the connecting mechanisms. The outer wall of the winding drum located at the right end of the base is wound with a BOPP film main body, and both ends of the BOPP film main body are respectively fixedly bonded to the outer walls of the two winding drums. The utility model can efficiently print the BOPP film, can flexibly scrape off the excess printing ink on the first roller, and can flexibly disassemble the printed BOPP film, with convenient operation and high working performance.

[0004] However, during the actual use of this structure, a segmented processing method is usually adopted, which cannot perform rapid all-round limiting and fastening operations on the high-temperature resistant BOPP film. As a result, during the actual processes of preheating, printing, and recycling of printing coatings, the BOPP film cannot be maintained in a relatively stable fastened state at all positions. Moreover, the overall production line is relatively long, making it difficult for workers to control it more conveniently, and production problems are more likely to occur. It cannot be quickly maintained. At the same time, the overall equipment cannot perform rapid adaptive adjustment operations according to the actual size of the BOPP film. Therefore, it is necessary to comprehensively adjust the entire production line, resulting in a relatively long production suspension time, which is not conducive to daily use. Therefore, it is urgent to design a high-temperature resistant BOPP film printing mechanism to solve the above problems. Summary of the Invention

Moreover, the overall production line is relatively long, making it difficult for workers to control it more conveniently, and production problems are more likely to occur. It cannot be quickly maintained. At the same time, the overall equipment cannot perform rapid adaptive adjustment operations according to the actual size of the BOPP film.

[0015] Preferably, a rotating groove is formed on the top of the equipment frame, and rotating shafts are arranged at both ends of the printing roller.

[0016] Preferably, a movable vehicle frame is fixedly connected to the bottoms of the second connecting seat and the cylinder seat, and universal wheels are arranged at the four corners of the bottom of the movable vehicle frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The high-temperature resistant BOPP film printing mechanism, through the set support frame, fixed frame, movable frame, first stabilizing frame, second stabilizing frame, stabilizing roller, support bottom frame, second connecting seat, limiting frame, protective rubber pad, equipment frame, printing roller, paint scraping frame and heating seat, can ensure that the BOPP film body is more efficient and stable during the whole printing process. Before printing and processing, the staff first passes the BOPP film body to be processed into the inside of the fixed frame and the movable frame from the film inlet groove of the support frame, and then winds the whole BOPP film body around the square frame structure composed of the first stabilizing frame and the second stabilizing frame. At this time, the stabilizing rollers inside the first stabilizing frame and the second stabilizing frame can perform stable support and conveying operations on the four sides of the corners of the BOPP film body. Finally, the whole BOPP film body is passed out from the bottom of the support frame through the film outlet groove. During the process of the BOPP film body being conveyed and connected with the film inlet groove and the film outlet groove, it can be respectively butted with the support bottom frame at the bottom of the corresponding support frame. The BOPP film body passes through the conveying groove of the support bottom frame and is stably limited by the conveying roller, so as to ensure that the whole BOPP film body is further limited at the bottom of the support frame and improve the overall conveying stability. After the preliminary laying of the BOPP film body is completed, the driving and printing operation of the support bottom frame can be carried out. At this time, the equipment frame connected to the first cylinder can first perform preheating operation on the BOPP film body in contact through the heating seat on the right side. The preheated BOPP film body comes to the surface of the printing roller for rapid surface printing. After printing, the BOPP film body comes to one side of the paint scraping frame of the equipment frame for the recovery operation of the excess paint. Thus, through the three-dimensional vertical conveying method of the BOPP film body, the overall printing production line of the BOPP film body becomes shorter, which is convenient for the maintenance work when problems occur in subsequent printing. And through the design of the limiting frame and the protective rubber pad, the stable limitation of the outer surface of the BOPP film body can be ensured, and the overall processing stability is improved, reflecting the practicality of the equipment design.

[0019] This high-temperature resistant BOPP film printing mechanism can further improve the overall usage effect of the equipment through the set movable frame, first sliding groove, second sliding groove, damping seat, through groove, first cylinder, cylinder frame, second cylinder, threaded seat, magnetic attraction seat, L-shaped sliding block, threaded hole and bolt. During daily use, the staff can slide the movable frame left and right on the surface of the support frame. At this time, the L-shaped sliding blocks at both ends of the bottom of the movable frame slide inside the first sliding groove and the second sliding groove, and adjust the distance between the fixed frame and the movable frame to the width position adapted to the BOPP film body to be printed. Then, fix the bolt to the threaded hole at one end of the bolt to fix both sides of the support frame, and quickly fasten the entire movable frame on the surface of the support frame, so as to ensure that the BOPP film body can be supported adaptively. And usually, by adjusting the first cylinder, the entire equipment frame can be adjusted for the printing position inside the BOPP film body. The second cylinder can perform an adaptive adjustment operation on the position of the limiting frame connected to one end through the threaded seat to make it more adapted to limit the BOPP film body. At the same time, the entire second connecting seat can be connected by magnetic attraction through the magnetic attraction seat, and then quickly moved through the universal wheels at the bottom of the movable vehicle frame, and the entire second connecting seat is removed from the through groove, and the entire equipment frame and the limiting frame can be quickly disassembled and replaced. Finally, dock the docking seat with the docking groove, and the magnetic attraction seat can quickly complete the assembly work, more efficiently meet the production requirements of BOPP film bodies of different sizes, improve the overall printing efficiency, meet the daily use requirements, and reflect the comprehensiveness of the equipment design.

As a whole, the second connecting seat 15 can be connected by adsorption through the magnetic attraction seat 28, and then the universal wheels 41 at the bottom of the movable vehicle frame 40 are used for rapid movement operation. The whole second connecting seat 15 is moved out from the through groove 14, and the whole equipment frame 23 and the limiting frame 20 are quickly disassembled and replaced for use. Finally, the docking seat 37 is docked with the docking groove 36, and adsorption by the magnetic attraction seat 28 can quickly complete the assembly work, more efficiently meeting the requirements of the production of BOPP film bodies 8 of different sizes and improving the overall printing efficiency.

[0033] Working principle: When in use, the operator first inserts the BOPP film body 8 to be processed into the inside of the fixed frame 3 and the movable frame 4 through the film inlet groove 30 of the support frame 1, and then winds the entire BOPP film body 8 around the square frame structure composed of the first stabilizing frame 5 and the second stabilizing frame 6. At this time, the stabilizing rollers 7 inside the first stabilizing frame 5 and the second stabilizing frame 6 can perform stable support and conveying operations on the four sides of the corners of the BOPP film body 8. Finally, the entire BOPP film body 8 is passed out of the bottom of the support frame 1 through the film outlet groove 29. During the process of conveying and connecting the BOPP film body 8 with the film inlet groove 30 and the film outlet groove 29, it can be respectively docked with the support chassis 9 at the bottom of the corresponding support frame 1. The BOPP film body 8 passes through the conveying groove 31 of the support chassis 9 and is stably limited by the conveying roller 32, so as to ensure that the entire BOPP film body 8 is further limited at the bottom of the support frame 1, improving the overall conveying stability. After the preliminary laying of the BOPP film body 8 is completed, the transmission printing operation of the support chassis 9 can be carried out. At this time, the equipment frame 23 connected to the first cylinder 16 can first perform preheating operation on the BOPP film body 8 in contact through the heating seat 26 on the right side. The preheated BOPP film body 8 comes to the surface of the printing roller 24 for rapid surface printing. After printing, the BOPP film body 8 comes to the side of the paint scraping frame 25 of the equipment frame 23 for the recovery operation of excess paint. Thus, through the three-dimensional vertical conveying method of the BOPP film body 8, the overall printing production line of the BOPP film body 8 is shortened, facilitating the maintenance work in case of subsequent printing problems. And through the design of the limiting frame 20 and the protective rubber pad 21, the stable limiting of the outer surface of the BOPP film body 8 can be ensured. During daily use, the operator can slide the movable frame 4 left and right on the surface of the support frame 1. At this time, the L-shaped sliding blocks 33 at both ends of the bottom of the movable frame 4 slide inside the first sliding groove 10 and the second sliding groove 11, and the distance between the fixed frame 3 and the movable frame 4 is adjusted to the width position adapted to the BOPP film body 8 to be printed. Then, the bolt 35 is fixed to the threaded hole 34 at one end of the bolt 35 to fix both sides of the support frame 1, and the entire movable frame 4 is quickly fastened to the surface of the support frame 1, so as to ensure that the BOPP film body 8 can be supported adaptively. And during daily use, the position of the printing can be adjusted by adjusting the first cylinder 16 so that the entire equipment frame 23 is inside the BOPP film body 8. The second cylinder 18 can perform the position adaptation adjustment operation on the limiting frame 20 connected to one end through the threaded seat 19 to make it more adapted to and limit the BOPP film body 8. At the same time, the entire second connecting seat 15 can be connected by a magnetic adsorption seat 28. Then, through the universal wheels 41 at the bottom of the movable vehicle frame 40, it can be quickly moved, and the entire second connecting seat 15 is moved out from the through groove 14.The quick device rack 23 and the limit rack 20 are quickly disassembled and replaced as a whole. Finally, the docking seat 37 is docked with the docking groove 36, and the magnetic attraction seat 28 adsorbs to quickly complete the assembly work, more efficiently meeting the requirements of the production of BOPP film bodies 8 of different sizes and improving the overall printing efficiency. The above is the entire working principle of the present invention.
