Abstract
Description
Technical Field
[0001] This invention relates to printing equipment, and more specifically to a metering gluing device for use in a varnishing machine. Background Technology
[0002] Currently, fully automatic varnishing machines and laminating machines are specialized printing equipment used for varnishing and laminating paper and board materials. They respectively achieve paper varnishing and paper-plastic composite paper processing, improving the quality and grade of the paper. Their metering and gluing devices include an upper plate, rubber rollers, and a metering roller. The rubber roller and metering roller are adjacent to each other, and varnishing oil is applied between them. When not in operation, the rubber roller and metering roller must be separated, requiring frequent manual adjustment, which is cumbersome and inefficient. Furthermore, the amount of oil (i.e., the amount of glue) is difficult to control precisely, resulting in inconsistent control of the dry oil and glue on paper of the same specification. After gluing, if there is a difference in glue thickness on the left and right sides of the rubber roller, it is impossible to adjust the displacement synchronously using the metering roller. Therefore, a device is needed that can control the distance between one side of the rubber roller and metering roller individually, or simultaneously control the distance between the left and right sides of the metering roller and rubber roller, to maintain the relative parallelism and uniform gluing of the metering roller and rubber roller. This ensures that the quality of the varnished paper product meets the expected level and guarantees the quality of the paper varnishing. Summary of the Invention
[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a dual-control adjustable metering adhesive application device that can be adjusted on one side or both sides simultaneously, effectively controlling the uniform application of oil on both sides.
[0004] The objective of this invention is achieved through the following technical solution: a dual-control adjustable metering and gluing device, comprising an upper wall plate, a rubber roller, and a metering roller. Metering roller blocks are mounted on the upper wall plate and at both ends of the metering roller. These metering roller blocks are connected to and fitted onto an adjusting rod via a helical tube. An adjusting handwheel is mounted on the outer end of the adjusting rod. A worm gear shaft is fitted over the helical tube, and a worm gear is mounted on the worm gear shaft. A synchronous adjusting plate is mounted on the upper wall plate and on the side of the worm gear. A worm seat is mounted on the synchronous adjusting plate. A synchronous adjusting shaft is installed between the worm seats, and a worm connected to the worm gear is mounted on the synchronous adjusting shaft. A synchronous handwheel is mounted on the outer end of the synchronous adjusting shaft.
[0005] The adjusting rod is threaded into a spiral tube, which is threaded into the worm gear shaft. An adjusting seat is mounted on the spiral tube, which connects to the metering roller block. An inner frame window is provided on the upper wall plate, within which the metering roller block, adjusting seat, spiral tube, adjusting rod, and worm gear shaft are mounted. A thrust ball bearing is mounted inside the worm seat and on the synchronous adjusting shaft near the worm.
[0006] With the structure of this invention, the worm gear drives the worm wheel to rotate by operating the synchronous handwheel. The worm wheel shaft rotates on its own axis, driving the solenoid tube forward and backward, which in turn moves the adjusting seat and the metering roller lever forward and backward, ultimately adjusting the distance between the metering roller and the rubber roller. Synchronous adjustment of the left and right sides of the metering roller is achieved through the synchronous adjusting shaft. By rotating the adjusting handwheel, the adjusting rod rotates, which in turn drives the solenoid tube to rotate, simultaneously pulling the adjusting seat and the metering roller lever forward and backward, allowing adjustment of only one side of the metering roller. This effectively controls the uniform oiling of both sides of the rubber roller, resulting in convenient operation, high work efficiency, and improved paper varnishing quality.

[0010] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0011] Reference Figures 1 to 3 As can be seen, the present invention applies to a dual-control adjustable metering and gluing device for a paper varnishing machine, comprising an upper wall plate 1 (one piece on each of the left and right sides), a rubber roller 2, and a metering roller 3. Metering roller blocks 4 are mounted on the upper wall plate 1 and at both ends of the metering roller 3. The metering roller blocks 4 are connected and fitted to an adjusting rod 16 via a solenoid 15. An adjusting handwheel 10 is mounted on the outer end of the adjusting rod 16. A worm gear shaft 14 is fitted over the solenoid 15, and a worm gear 11 is mounted on the worm gear shaft 14. A synchronous adjusting plate 9 is mounted on the upper wall plate 1 (both sides on the front) and at the side of the worm gear 11. A worm seat 8 is mounted on the synchronous adjusting plate 9. A synchronous adjusting shaft 5 is mounted between the worm seats 8. A worm 6 connected to the worm gear 11 is mounted on the synchronous adjusting shaft 5. A synchronous handwheel 12 (one piece is sufficient) is mounted on the outer end of the synchronous adjusting shaft 5 (passing through the worm seat 8).
[0012] The adjusting rod 16 is threaded into the screw tube 15, which in turn is threaded into the worm gear shaft 14. An adjusting seat 13 is mounted on the screw tube 15, and this adjusting seat 13 is connected to the metering roller block 4. An inner frame window 17 is provided on the upper wall plate 1, and the metering roller block 4, adjusting seat 13, screw tube 15, adjusting rod 16 (partially), and worm gear shaft 14 (partially) are mounted within the inner frame window 17. A thrust ball bearing 7 is mounted inside the worm seat 8 and on the synchronous adjusting shaft 5 near the worm 6. The upper wall plate 1, metering roller block 4, adjusting seat 13, screw tube 15, adjusting rod 16, worm gear shaft 14, synchronous adjusting plate 9, worm seat 8, worm 6, thrust ball bearing 7, adjusting handwheel 10, and worm gear 11 are all present on both the left and right sides.
[0013] As shown in the attached diagram, the worm gear 11 and worm gear shaft 14 are connected and rotate via a flat key, and are engaged by a threaded connection between the worm gear shaft 14 and the solenoid tube 15. Operating the synchronizing handwheel 12 causes the worm 6 to drive the worm gear 11 to rotate. The worm gear shaft 14, for its fixed rotation, drives the solenoid tube 15 forward and backward, causing the adjusting seat 13 and the metering roller block 4 to also move forward and backward, ultimately adjusting the distance between the metering roller 3 and the rubber roller 2. Synchronous adjustment of the left and right sides is achieved via the synchronizing adjusting shaft 5. The adjusting rod 16 and the solenoid tube 15 are engaged by a threaded connection. Rotating the adjusting handwheel 10 drives the adjusting rod 16 to rotate, which in turn drives the solenoid tube 15 to rotate. The adjusting seat 13 and the metering roller block 4 are fixed by screws. The rotation of the solenoid tube 15 simultaneously pulls the adjusting seat 13 and the metering roller block 4 forward and backward, thus achieving adjustment of one side of the metering roller; the other side is adjusted similarly.
