Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment, and in particular relates to a discharging device of a gravure printing machine. Background Art

[0002] A gravure printing press is a machine that uses an intaglio plate for printing. The image and text portion of the printing plate is recessed, while the blank portion is flush with the outer diameter of the plate cylinder. Most existing gravure printing presses use pneumatic shafts for loading and unloading, which are relatively expensive. They also make reel changes very cumbersome, labor-intensive, and inefficient, and make it difficult to adjust the lateral position of the reel on the reel. Furthermore, existing gravure printing presses typically use a dual-station rotary rack for unloading, which has the disadvantages of requiring a large footprint, strictly limiting the reel diameter, and requiring high labor intensity for loading and unloading.

[0003] A utility model with authorization announcement number CN201516720U, after searching, discloses a loading and unloading mechanism for a gravure printing machine, comprising a bracket, an unwinding arm, and an unwinding shaft. The unwinding arm is mounted on the bracket, and the unwinding shaft is mounted on the unwinding arm. The utility model is characterized in that: the unwinding shaft is composed of two coaxially mounted left and right conical top shafts, the left conical top shaft being rotatably connected to the left arm of the unwinding arm, one end of the left conical top shaft being provided with a conical head, and the other end being connected to an adjustment device; the right conical top shaft being rotatably connected to the right arm of the unwinding arm, one end of the right conical top shaft being provided with a conical head, and the other end being connected to an automatic pressing device, with the conical heads of the left and right conical top shafts facing each other. The utility model is convenient for loading and unloading, has high loading and unloading efficiency, and is easy to adjust the position of the material roll. At the same time, it occupies a small area, has a large retractable material roll diameter, and is low in cost.

[0004] The above technical solution is structurally provided with a unwinding arm, and there is only one unwinding shaft station on the unwinding arm, which occupies a small area and can retract and unwind a large material roll. When loading, it is only necessary to place and fix the material roll on the unwinding arm according to the position (at this time the material roll is in contact with the ground), and then the oil cylinder is activated to automatically lift the material roll to the appropriate working position. Unloading and loading are very convenient, with a high degree of automation and reduced labor intensity. However, the above technical solution only has one unwinding shaft station, which results in that when unloading is required, the material can only be unloaded first and then the material roll can be placed on the unwinding shaft for winding operation, making the winding and unloading operations discontinuous, thereby affecting the processing and unloading efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0027] In a specific embodiment of the present invention, by using the rotating motor 11 and the first mounting plate 8 in conjunction, when the device needs to unload, the rotating motor 11 can be started to drive the first mounting plate 8 and then the positions of the mounting mechanisms 9 at both ends and the rollers on their surfaces can be adjusted, so that the winding can be completed while unloading. This avoids the problem that the current solution only has one unwinding shaft station, resulting in discontinuous winding and unloading operations, affecting the processing and unloading efficiency, thereby improving the efficiency of the unloading device of the gravure printing machine.

[0028] Specifically, the four corners of the bottom of the platform 1 are fixedly connected with support legs 2 , and a plurality of heat dissipation holes 10 are opened on the surface of the installation box 7 .

[0029] In a specific embodiment of the present invention, the setting of the support legs 2 makes the device stand upright and stable, and the setting of the heat dissipation holes 10 prevents the rotating motor 11 in the installation box 7 from overheating during operation and requires frequent maintenance, thereby improving the stability and economy of the gravure printing machine unloading device.

[0030] Specifically, a plurality of moving rollers 13 are installed at the bottom of the moving plate 4 , a through hole 12 is opened on the surface of the moving plate 4 , and the output end of the rotating motor 11 passes through the through hole 12 and is connected to the first mounting plate 8 .

[0037] In a specific embodiment of the present invention, the connection cartridge 16 is provided so that it can be stably connected to the roller shaft to avoid falling during operation, thereby improving the safety of the unloading device of the gravure printing press.

[0038] Working principle: When using this device to perform winding and unloading operations, start the electric push rod 5 to drive the moving plate 4 to drive the first mounting plate 8 and the winding drum on its surface to approach the gravure printing machine body 3. After the winding drum is installed through the connecting clamp 16, printing and discharging are carried out through the gravure printing machine body 3. When unloading is required, ensure that the winding drum for winding at the lower end is installed through the connecting clamp 16, and start the rotating motor 11 installed inside the mounting box 7 to drive the first mounting plate 8 to rotate, and drive the winding drum at the lower part of the first mounting plate 8 to rotate to the upper part. At this time, the reel at the upper end rotates to the lower end, so that the device can rewind while unloading, saving time and speeding up unloading efficiency.
