Description
Technical Field
[0001] The utility model relates to the technical field of cooling devices, in particular to a printing roller cooling device for a wide-width printing machine. Background Technique
[0002] For the curved surface printing of cylindrical containers or conical containers, two pairs of roller supports can be used. For covers and cups, bushing supports are used. Soft hollow containers can be supported by an inflation device. The elliptical surface is approximately a part of a cylindrical surface and can be supported by the method of inlaying a cylinder. The principle of printing on the surface of a cone is basically the same as that of printing on the surface of a cylinder. The difference lies in the graphic shape of the screen printing plate and the movement form of the screen printing plate. When making a screen printing plate for printing on the surface of a cone, first draw the developed view of the cone surface, find the center of the sector according to the developed view, and then select an appropriate screen frame to make the screen printing plate. The conical printing object is in line contact with the screen printing plate under a certain squeegee pressure. When the screen printing plate makes a horizontal sector movement around the axis of the sector developed view, the printing object makes a synchronous rotational movement on the supporting device. The ink is squeezed by the squeegee and leaks onto the surface of the printing object to complete the printing.
[0003] However, it still has some disadvantages. For example, when the wide-width printing machine is used for a long time, the printing surface at the printing outlet will fall off and deform due to the too high temperature of the printed material, and the water pipe connected to the cooling roller in the printing machine is not convenient to use during the operation of the printing machine.
[0004] To solve the above problems, a printing roller cooling device for a wide-width printing machine is proposed in this application. Content of the Utility Model
[0005] The purpose of the utility model is to provide a printing roller cooling device for a wide-width printing machine to solve the problems in the prior art that the water pipe for cooling is not convenient to use after being connected to the printing machine and the cooling water flows slowly in the cooling roller after being transported into the cooling roller as mentioned in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A printing roller cooling device for a wide-width printing machine, including a cooling roller, the outer surface of the left end of the cooling roller is movably connected with a disc, the outer surface of the left end of the disc is fixedly connected with a short pipe, the outer wall of the short pipe is movably sleeved with a quick docking device, and the left end of the quick docking device is movably sleeved with a water pipe.
[0007] Preferably, the outer surface of one end of the cooling roller is movably connected with a disc, and the right end of the disc is movably connected with a cooling device.
[0008] Preferably, the quick docking device includes a nut, a round cover, a notch, a rotary knob, a short column, a round bead, a screw rod and a fastening ring. The outer wall of the short pipe is movably sleeved with the short column. The outer wall of the short column is fixedly connected with the rotary knob. A notch is formed on the outer surface of the left end of the short column.
[0009] Preferably, a round bead is movably connected to the inner wall of the left end of the short column. The round cover is movably sleeved on the inner wall of the notch. The fastening ring is movably sleeved on the outer wall of the short column. The screw rod is threadedly connected to the outer wall of the fastening ring. The nut is threadedly connected to the outer wall of the screw rod.
[0010] Preferably, the cooling device includes a waterproof ring, a first connecting pipe, a second connecting pipe, a second threaded pipe, a double-headed pipe, a first threaded pipe, a long pipe, a threaded inner pipe and a round pipe. The long pipe is movably connected to the outer surface of the right end of the disc. The round pipe is fixedly connected to the outer wall of the long pipe. The threaded inner pipe is fixedly connected to the outer surface of the upper end of the round pipe.
[0011] Preferably, the waterproof ring is movably connected to the outer wall of the threaded inner pipe. The first threaded pipe is threadedly connected to the outer wall of the waterproof ring. The first connecting pipe is fixedly connected to the outer surface of the upper end of the first threaded pipe. The double-headed pipe is fixedly connected to the outer surface of the upper end of the first connecting pipe. The second connecting pipe is fixedly connected to the outer surface of the upper end of the double-headed pipe. The second threaded pipe is fixedly connected to the outer surface of the upper end of the second connecting pipe.
[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0013] Through the cooperation between the round bead and the fastening ring in the quick docking device provided by the present invention, the water pipe is placed in the inner wall of the short column, and then the water pipe is fastened by the screw rod and the nut on the outer wall of the fastening ring. The round bead installed on the inner wall of the short column can prevent the water pipe installed in the inner wall of the short column from rotating together with the cooling roller when rotating, and it will not affect the delivery of cold water from the water pipe into the cooling roller. The quick docking device can quickly dock the water pipe with the cooling roller.
[0014] Through the cooperation between the double-headed pipe and the long pipe in the cooling device provided by the present invention, the second connecting pipe and the second threaded pipe installed at both ends of the double-headed pipe and the first connecting pipe and the first threaded pipe are used to dock multiple long pipes inside the cooling roller.

When the long pipe rotates with the cooling roller, the double-headed pipe installed on the outer wall of the long pipe will transfer the water in the long pipe to another long pipe inside the cooling roller for cooling treatment. And so on, and finally the water is discharged outside the cooling roller. BRIEF DESCRIPTION OF THE DRAWINGS

The outer wall of the fastening ring 14 is threadedly connected with the screw rod 13. The outer wall of the screw rod 13 is threadedly connected with the nut 7. By providing the ball 12, the water pipe 4 installed in the inner wall of the short column 11 can be prevented from rotating together with the cooling roller 1.
[0023] In this embodiment, as Figure 4 shown, the temperature reduction device 6 includes a waterproof ring 15, a first connecting pipe 16, a second connecting pipe 17, a second threaded pipe 18, a double-headed pipe 19, a first threaded pipe 20, a long pipe 21, a threaded inner pipe 22 and a round pipe 23.

[0024] Working principle:
[0025] Before using the printing roller cooling device of a wide-width printing machine, first place one end of the water pipe 4 into the inner wall of the short column 11 in the quick docking device 3, and then use the fastening ring 14 in the quick docking device 3 to fasten the screw 13 and the nut 7. The cooling device 6 can be connected to the long pipe 21 through the second connecting pipe 17 and the second threaded pipe 18 at the upper and lower ends of the double-headed pipe 19 in the cooling device 6, the first connecting pipe 16 and the first threaded pipe 20. When using the printing roller cooling device of a wide-width printing machine, first discharge the cooling water through the water pipe 4 into the inner wall of the cooling roller 1. When the water pipe 4 is connected to the cooling roller 1 and discharges the cooling water, the cooling roller 1 can continue to rotate and work because the ball 12 installed on the inner wall of the short column 11 in the quick docking device 3 connected to the water pipe 4 allows the water pipe 4 to rotate within the inner wall of the short column 11 without driving the water pipe 4 to rotate, and the fastening ring 14 installed on the outer wall can fasten the water pipe 4, effectively preventing the water pipe 4 from detaching. When the cooling water inside the water pipe 4 enters the inside of the cooling roller 1, it will flow into the long pipe 21 in the cooling device 6. There are multiple long pipes 21 inside the cooling roller 1, and all these long pipes 21 are connected to the double-headed pipe 19. When the cooling roller 1 rotates, its inside will also rotate accordingly. The long pipe 21 that is filled with cooling water first will, with the rotation of the external cooling roller 1, transport the cooling water inside it into other long pipes 21 through the double-headed pipe 19 installed on the outer wall of the long pipe 21 for circulating cooling treatment.
[0026] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present invention.
