Description

Technical Field

[0001] The utility model relates to the technical field of plate roller production devices, in particular to a gravure polishing and waterproofing device. Background Art

[0002] The plate roller is a tool used for plate making. The surface of the roller is usually coated with copper, and the pattern is engraved by the engraving process of the gravure electronic engraving machine. It is then plated with chrome again to increase its durability. After completion and delivery to the printing factory, they are often used for printing work in related fields such as plastic packaging.

[0003] After the plate roller is plated, it needs to be polished. The current polishing method is to install the plate roller between the plate roller heads of the polishing machine, so that the plate roller can rotate under the drive of the plate roller heads and be polished by the movable polishing roller on the polishing machine. One of the plate roller heads of the polishing machine is connected to the motor power output end of the polishing machine through a mounting seat, and the other is mounted on a mounting seat that can be displaced by a guide rail. The plate roller is fixed between the plate roller heads through the slots at both ends and rotates under the drive of the motor.

[0004] The current polishing machine has the following problems during polishing after installing the plate roller: the flushing water used for polishing will enter the gap between the two ends of the plate roller and the installation of the plate roller head, making the slots at both ends of the plate roller and both ends of the plate roller head easy to rust, reducing the durability of the plate roller and the plate roller head. Utility Model Content

[0005] In order to overcome the problems in the background technology, the utility model provides a gravure polishing waterproof device to solve the problem that the flushing water in the existing gravure polishing device will enter the gap between the two ends of the plate roller and the plate roller head connection installation, causing the slots at both ends of the plate roller and the two ends of the plate roller head to rust.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] A gravure polishing waterproof device comprises a control sleeve, a push rod device, a connecting sleeve, a waterproof sleeve, a mounting seat and a cylinder, wherein the control sleeve is coaxially mounted on both ends of a plate roller head of the gravure polishing device for fixing a plate roller, the push rod device is mounted in the control sleeve, the connecting sleeve is coaxially slidably mounted on the plate roller head at one end of the control sleeve on the inner side, one end of the connecting sleeve extends into the control sleeve and is connected to the telescopic end of the push rod device, and the other end is connected to the waterproof sleeve coaxially slidably mounted on the plate roller head, the mounting seat is fixed on the outer side of the control sleeve and is connected to the gravure polishing device, and a PLC cylinder is arranged in the cylinder and is connected to the push rod device.

[0008] Furthermore, a limiting ring is provided at one end of the connecting sleeve connected to the waterproof sleeve, a limiting block is provided on the top of the plate roller, the waterproof sleeve is coaxially installed on the limiting ring, and a limiting groove is provided at the head end of the waterproof sleeve to fit with the limiting block.

[0018] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0019] The utility model discloses a concave polishing waterproof device, referring to Figure 1-3A gravure polishing waterproof device comprises a control sleeve 1, a push rod device 2, a connecting sleeve 3, a waterproof sleeve 4, a mounting seat 5 and a cylinder 6. The control sleeve 1 is coaxial with the plate roller head 7 of the gravure polishing device, the push rod device 2 is installed in the control sleeve 1, the connecting sleeve 3 is coaxially slidably installed on one side of the free end of the plate roller head 7, one end of the connecting sleeve 3 extends into the control sleeve 1 and is connected with the telescopic end of the push rod device 2, and the other end is connected to the waterproof sleeve 4 coaxially slidably installed with the plate roller head 7, the mounting seat 5 is fixed on the outside of the control sleeve 1, and the cylinder 6 is connected to the push rod device 2.

[0020] The through hole in the middle of the control sleeve 1 can be used as a bearing for the rotation of the plate roller head 7 after the plate roller head 7 is installed. The push rod device 2 is installed in the control sleeve 1 and controls the movement of the telescopic end to make the connecting sleeve 3 connected thereto move forward and backward. The connecting sleeve 3 moves forward on the plate roller head 7 to enable the waterproof sleeve 4 to seal the gap between the plate roller 8 and the plate roller head 7 to prevent the flushing water from entering the gap between the two ends of the plate roller and the plate roller head, causing the slots at both ends of the plate roller 8 and the two ends of the plate roller head 7 to rust. The mounting seat 5 is fixed to the outside of the control sleeve 1, wherein the mounting seat 5 on one side of the motor power output end is fixedly installed with the polishing machine, and the mounting seat 5 on the other side is installed with the guide rail on the polishing machine, and is connected with the plate roller head limit position to drive the plate roller head to move left and right, thereby realizing the replacement of the plate roller 8, and the cylinder 6 can control the push rod device 2 to start the mobile waterproof sleeve 4.

[0021] See also Figure 1-3 A limiting ring 31 is provided at one end where the connecting sleeve 3 is connected to the waterproof sleeve 4, a limiting block 71 is provided on the plate roller head 7, the waterproof sleeve 4 is coaxially installed on the limiting ring 31, and a limiting groove 41 is provided at the head end of the waterproof sleeve 4 to fit with the limiting block 71. The limiting block 71, the limiting groove 41 and the limiting ring 31 are designed to enable the waterproof sleeve 4 to rotate synchronously with the plate roller head 7, so that the gap between the waterproof sleeve 4 and the plate roller 8 and the plate roller head 7 is in a relatively static state, thereby avoiding friction that affects the waterproof effect.

[0022] See also Figure 1-3 The push rod device 2 is evenly and symmetrically arranged on the control sleeve 1 and fixedly connected with the connecting sleeve 3, so that the waterproof sleeve 4 can be evenly moved to seal the gap that needs waterproofing, avoiding sealing deviation caused by uneven thrust.

[0023] See also Figure 1-3 The waterproof cover 4 is a flexible silicone waterproof cover. The diameter of the head end of the waterproof cover 4 gradually decreases to form a bottle stopper shape and has an interference fit with the mounting grooves of the plate roller head 7 and the plate roller 8 to improve the sealing and waterproof effect.

[0024] Working process:

[0025] Install the plate roller 8 between the two sections of the plate roller top heads 7. Before polishing, start the push rod device 2 in the control sleeve 1 through the cylinder 6, and the telescopic end moves forward through the connecting sleeve 3 to push the waterproof sleeve 4, so that the limit block 71 enters the limit groove 41. The gap between the head end of the waterproof sleeve 4 and the plate roller 8 and the plate roller top head 7 is sealed. Then start the motor to drive the plate roller top head 7 and the plate roller 8 to rotate for polishing. After polishing is completed, the waterproof sleeve 4 is controlled to retreat by the cylinder 6 to facilitate the removal of the plate roller 8.

[0026] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
