Description

Technical Field

[0001] The utility model relates to the field of printing plate roller devices, in particular to a plate roller for gravure printing. Background Art

[0002] Printing is a technology that uses processes such as plate making, inking, and pressurization to transfer ink from text, pictures, photos, anti-counterfeiting manuscripts to the surface of paper, textiles, plastics, leather, PVC, PC, and other materials to batch reproduce the original content. Printing is the process of transferring the approved printing plate to the substrate through a printing machine and special ink. The plate roller, also called a steel roller, is divided into a hollow roller and a solid roller, a shaft roller and a non-shaft roller. It is generally used for plate making. The surface of the roller is copper-plated, and the pattern is engraved by a gravure electronic engraving machine, and then a layer of chrome is plated. After completion, it is delivered to the printing factory and is often used for printing operations on plastic packaging.

[0003] However, the problem with the existing plate rollers is that in order to print different graphics, the printing machine usually needs to replace the entire plate roller with different engraved patterns. Due to the large mass of the plate roller, it is inconvenient to replace it, and different graphics need to be printed on different plate rollers, which will lead to a waste of plate roller production materials. Utility Model Content

Through the provided frame and side panel structures, the user can remove the water collection bin and the water inlet bin on both sides during actual use, and pull the side panel structure out of the groove of the frame through the raised structure at the bottom end thereof to replace the plate roller with different patterns. The use of this pull-out structure can achieve the effect of rapid replacement, which is convenient for actual use and operation on site.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: a gravure printing roller comprises a frame, a side plate is fixed on the outer side of the frame, the frame is a hollow structure, and through holes are provided on both sides of the frame, a water collection bin is sleeved on both sides of the frame, a threaded column is fixed on the outer side of the middle part of the water collection bin, the water collection bin is a hollow structure, and the water collection bin includes a positioning ring and a positioning hole provided on the outer side of the positioning ring, a water inlet bin is arranged on the outer side of the positioning hole, the water inlet bin is a closed frame structure, a swivel is provided on the inner side wall of the water inlet bin, the water inlet bin is movably arranged with the water collection bin through the contact clamping of the swivel and the swivel, a clamping tube is provided on the inner side wall of the water inlet bin, the clamping tube and the positioning hole are kept in communication, a notch is provided on the outer side wall of the frame, a protrusion is provided on the bottom end of the side plate, the side plate is clamped in the notch by the protrusion to achieve fixed connection with the frame.

[0006] As a preferred technical solution of the utility model, a plurality of groups of notches are provided on the outer side of the frame, and each group of notches is trumpet-shaped with a larger inner side and a smaller outer side, and the number and size of the notches are compatible with the side panels.

[0007] As a preferred technical solution of the present invention, the through hole is connected to the internal cavity of the frame.

[0008] As a preferred technical solution of the utility model, the inner diameter of the positioning ring is matched with the outer diameter of the side plate.

[0009] As a preferred technical solution of the utility model, the middle part of the positioning ring is a hollow structure, and the middle part of the positioning ring is meshed with the outer side of the positioning column, and the threaded structure of the positioning column is two centimeters away from the bottom side.

[0010] As a preferred technical solution of the utility model, a T-shaped annular groove is provided on the cross section of the rotating ring, and a clamping ring is provided on the outer side of the water collection bin, and the clamping ring is arranged in the groove.

[0011] As a preferred technical solution of the utility model, a water inlet is arranged on the outside of the water inlet bin, and the water inlet is connected to the cavity in the water inlet bin.

[0012] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0013] 1. In this device, by setting up the frame and side panel structure, the user can remove the water collection bin and water inlet bin on both sides during actual use, and pull out the side panel structure from the notch of the frame through the raised structure at the bottom to replace the plate rollers with different patterns. The use of this pull-out structure can achieve the effect of rapid replacement, which is convenient for actual on-site operation.

[0014] 2. In this device, through the combined structure of water inlet bin and water collection bin, the user can connect the external water pipe to the water inlet, and then the liquid can enter the water inlet bin first. Through the connection between the card-set tube and the positioning hole, the liquid can smoothly enter the water collection bin. Finally, due to the fixed relationship between the positioning column and the positioning ring, there is a two-centimeter space between the side panel, so the liquid in the water collection bin will pass through the through hole and enter the frame, thereby achieving the heat dissipation effect inside the frame and maintaining a normal working temperature.

[0015] 3. In this device, by making the water collection bin and the water inlet bin movable, a swivel with a T-slot can be used to fix the clamping ring. Therefore, when the internal water collection bin rotates with the frame-side plate, the external water inlet bin will not rotate. The positioning holes and clamping tubes are only the inlet and outlet of the liquid and do not touch. Therefore, during the rotation process, the liquid will enter the water inlet bin from the fixed water inlet-clamping tube on one side, and then enter the positioning hole structure under the premise of ensuring rotation, so as to achieve the effect of liquid cooling. Both ends of the frame can be connected with the flowing cooling medium to achieve the need to maintain a constant temperature. BRIEF DESCRIPTION OF THE DRAWINGS
