Description

Technical Field

[0001] This utility model relates to the field of printing roller processing technology, and in particular to a water baffle structure for a printing roller grinding machine. Background Technology

[0002] The traditional manufacturing process for gravure printing rollers on the market is as follows: Seamless steel pipes are processed to create steel rollers according to the roller processing dimensions provided by the manufacturer. A layer of nickel is then plated onto the surface of the steel roller to improve the adhesion between the roller and the copper layer. After nickel plating, a layer of copper is plated onto the roller surface. The copper surface of the roller is then ground, polished, and patterns are engraved on the roller surface. Finally, chrome plating is applied to the roller to improve its wear resistance. During the grinding process of the copper surface of the roller, corrosive residual electroplating solution adhering to the roller will splash during the grinding process. Therefore, grinding machines usually have metal baffles. However, some existing grinding machines use gears and racks to drive the baffles up and down. A small amount of corrosive liquid can flow from the edges and gaps of the baffle onto the gears and racks, causing corrosion and hindering the up-and-down movement of the baffle. To solve this problem, some grinding machines have the bottom of the baffle connected to the grinding machine's trough by a hinge. Opening and closing the baffle requires manual tilting. Because the grinding machine is very long and the water baffle is also very heavy, manual turning is quite laborious. Therefore, it is necessary to invent a new water baffle structure for the printing roller grinding machine to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a water-blocking gate structure for a printing roller grinding machine, which solves the problems of corrosive liquid in the printing roller grinding machine corroding the gears and racks of the water-blocking gate, as well as the difficulty in opening and closing the flip-type water-blocking gate.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A water-blocking gate structure for a printing roller grinding machine includes a grinding machine trough and a water-blocking gate. Extended connecting plates are fixedly connected to both the left and right sides of the water-blocking gate, and the extended connecting plates are horizontally arranged. Cylinders are provided on both the left and right sides of the water-blocking gate, and the piston rods of the cylinders are vertically fixedly connected to the extended connecting plates.

[0006] Preferably, in conjunction with the above scheme, the extension connecting plates are symmetrically arranged on the left and right sides of the water-blocking gate, and the cylinders are also symmetrically arranged on the left and right sides of the water-blocking gate.

[0007] Preferably, in conjunction with the above scheme, the extension connecting plate has an L-shaped structure, and the lower end of the extension connecting plate is fixedly connected to the upper ends of the left and right sides of the water-blocking gate.

[0008] Preferably, in conjunction with the above scheme, baffles are fixedly connected to both the left and right sides of the front opening of the grinding machine tank, and the extension connecting plate is movably connected to the baffles.

[0009] Preferably, in conjunction with the above scheme, a limiting groove is formed on the baffle along the height direction, and the extension connecting plate is movably connected in the limiting groove.

[0010] Preferably, in conjunction with the above scheme, the upper end of the cylinder piston rod is fixedly connected to the extension connecting plate by screwing.

[0011] Preferably, in conjunction with the above scheme, mounting plates are fixedly connected to the lower parts of both the left and right sides of the grinding machine tank, and the bottom of the cylinder is fixedly connected to the mounting plates.

[0012] The beneficial effects of this utility model are as follows: By using the water baffle structure of the roller grinding machine of this utility model, the water baffle is raised and lowered by setting cylinders on both sides of the grinding machine tank, and the piston rod of the cylinder is connected by an extension connecting plate, so that the cylinder assembly is far away from the front opening of the grinding machine tank. This can effectively prevent corrosive liquids from corroding the lifting mechanism of the water baffle, and also solve the problem of the difficulty of manually flipping the water baffle.

[0013] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0014] Figure 1 This is a structural diagram of a water baffle gate for a printing roller grinding machine according to the present invention. Detailed Implementation

[0015] like Figure 1 The diagram shows a water baffle structure for a printing roller grinding machine, including a grinding machine trough 1 and a water baffle 2 movably connected to the front opening of the grinding machine trough 1. The front opening is used for workers to place and remove printing rollers. Extension connecting plates 3 are fixedly connected to both the left and right sides of the water baffle 2, and the extension connecting plates 3 are horizontally arranged. Cylinders 4 are provided on both the left and right sides of the water baffle 2, and the piston rods of the cylinders 4 are vertically fixedly connected to the extension connecting plates 3.

[0016] To prevent the corrosive liquid from corroding the cylinder assembly, the extension connecting plate 3 is symmetrically arranged on the left and right sides of the water baffle 2, and the cylinder 4 is also symmetrically arranged on the left and right sides of the water baffle 2, so as to avoid the opening of the grinding machine tank 1 and the gap of the water baffle 2.

[0017] To facilitate the connection of various parts and better prevent liquid corrosion of the cylinder assembly, the extension connecting plate 3 has an L-shaped structure. The lower end of the extension connecting plate 3 is fixedly connected to the upper ends of the left and right sides of the water baffle 2. The L-shaped extension connecting plate 3 has a short side and a long side. The short side is fixedly connected to the upper end of the water baffle 2 by welding, and the long side is kept as far away from the sides of the water baffle 2 as possible, so that the corrosive liquid will not corrode the cylinder assembly.

[0018] In order to further block the corrosive liquid and prevent the cylinder assembly from being corroded, while not hindering the up and down movement of the extension connecting plate 3, baffles 5 are fixedly connected to both sides of the front opening of the grinding machine tank 1, and the extension connecting plate 3 is movably connected to the baffles 5.

[0019] To facilitate the up-and-down movement of the extension connecting plate 3, a limiting groove 6 is provided on the baffle 5 along the height direction, and the extension connecting plate 3 is movably connected in the limiting groove 6.

[0020] To facilitate the fixing of cylinder 4 and extension connecting plate 3, the upper end of the piston rod of cylinder 4 is fixedly connected to extension connecting plate 3 by screws. Bolts can be welded to the upper end of the piston rod, passed through the fixing holes of extension connecting plate 3, and then fixed with nuts.

[0021] To facilitate the installation and fixation of the cylinder, mounting plates 7 are fixedly connected to the lower parts of the left and right sides of the grinding machine tank 1, and the bottom of the cylinder 4 is fixedly connected to the mounting plates 7.
