Description

Technical Field

[0001] The utility model relates to the technical field of CTP plate production, in particular to an anti-oil pollution CTP plate production device for automatically proportioning raw materials. Background Technique

[0002] CTP plates are materials for direct printing on a printing press. They are plates used in computer-to-plate (CTP) technology. CTP technology is an efficient and environmentally friendly digital pre-press plate-making technology. It eliminates the intermediate products used in the traditional plate-making process and realizes the direct connection from the computer to the printing. The accuracy and integrity of CTP plates are the key to the final product and one of the key factors restricting the development of CTP. If the surface of CTP plates is easily contaminated by oil stains after exposure imaging, the printing quality will decline, including the clarity, color reproduction, and overall visual effect of the printed matter may be affected.

[0003] To ensure the quality of printed matter, CTP plates need to have anti-oil pollution characteristics to prevent oil stain penetration and adhesion, thereby maintaining the clarity and accuracy of the printing plate. In the prior art, the anti-oil pollution treatment of CTP plates is mainly achieved through specific chemical treatments. The anti-oil pollution treatment of silver salt type CTP plates is a typical example. When performing anti-oil pollution treatment on silver salt type CTP plates, it is necessary to stir and mix silver halide solvents and developers. However, when adding and mixing silver halide solvents and developers by stirring, it is impossible to quantitatively add the two, resulting in an unqualified ratio, so that the developed solution containing silver halide solvents obtained by mixing cannot meet the usage requirements, and the anti-oil pollution treatment of silver salt type CTP plates cannot be achieved, with insufficient practicability. Therefore, it is necessary to redesign an anti-oil pollution CTP plate production device for automatically proportioning raw materials to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an anti-oil pollution CTP plate production device for automatically proportioning raw materials.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

A first motor connected to the rotating shaft is fixedly installed on the upper end face of the mixing tank. Multiple stirring blades are fixedly installed on the outer wall of the rotating shaft through an installation mechanism. A connecting pipe extending into the interior is fixedly installed on the upper end face of the mixing tank. A placement groove is opened on the upper end face of the processing table. A reciprocating lead screw is rotatably installed on the upper end face of the processing table through a moving frame. A second motor connected to the reciprocating lead screw is fixedly installed on the outer wall of the moving frame. A lead screw sleeve is threadedly installed on the outer wall of the reciprocating lead screw through a limiting mechanism. A spray pump is fixedly installed at the end of the lead screw sleeve through a fixing mechanism. A telescopic hose is fixedly installed on the outer wall of the inlet pipe of the spray pump. The inner wall of the telescopic hose is fixedly connected to the outer wall of the connecting pipe. A spray pipe is fixedly installed on the outer wall of the spray pump. Multiple spray holes communicating with the interior are opened on the outer wall of the spray pipe.

[0007] Preferably, the support mechanism includes a support plate fixedly installed on the outer wall of the processing table. The first metering pump, the second metering pump and the mixing tank are all fixedly installed on the upper end face of the support plate.

[0008] Preferably, the installation mechanism includes an installation sleeve fixedly installed on the outer wall of the rotating shaft. Each stirring blade is fixedly installed on the outer wall of the installation sleeve.

[0011] Preferably, a collection box is slidably installed on the outer wall of the processing table through a chute. Multiple leakage holes matching the collection box are opened on the bottom wall of the placement groove.

[0012] The beneficial effects of the present utility model:

[0013] 1.

Subsequently, the first motor can drive the rotating shaft to rotate, and the rotating shaft drives multiple stirring blades to rotate through the cooperation of the installation sleeve.

[0014] 2.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] A connecting pipe 10 extending to the interior is fixedly installed on the upper end surface of the mixing box 5, a placement groove is opened on the upper end surface of the processing table 1, a reciprocating screw 12 is rotatably installed on the upper end surface of the processing table 1 through a moving frame 11, a second motor 13 connected to the reciprocating screw 12 is fixedly installed on the outer wall of the moving frame 11, and a screw sleeve 15 is threadedly installed on the outer wall of the reciprocating screw 12 through a limiting mechanism. The limiting mechanism includes a limiting rod 14 fixedly installed inside the moving frame 11, and the limiting rod 14 slides through the screw sleeve 15. The limiting rod 14 can limit the screw sleeve 15, so that the screw sleeve 15 can only move axially along the outer wall of the reciprocating screw 12. A spray pump 17 is fixedly installed on the end of the screw sleeve 15 through a fixing mechanism, the fixing mechanism includes a fixing plate 16 fixedly installed on the end of the screw sleeve 15, the spray pump 17 is fixedly installed on the upper end surface of the fixing plate 16, a telescopic hose 18 is fixedly installed on the outer wall of the inlet pipe of the spray pump 17, the inner wall of the telescopic hose 18 is fixedly connected to the outer wall of the connecting pipe 10, a spray pipe 19 is fixedly installed on the outer wall of the outlet pipe of the spray pump 17, and a plurality of spray holes connected to the interior are opened on the outer wall of the spray pipe 19, a collecting box 20 is slidably installed on the outer wall of the processing table 1 through a slide groove, and a plurality of leakage holes cooperating with the collecting box 20 are opened on the bottom wall of the placement groove.

[0024] When the utility model is used, the silver halide solvent and the developer can be quantitatively pumped in proportion by the first metering pump 3 and the second metering pump 4, and pumped into the mixing box 5. Then, the first motor 7 can drive the rotating shaft 6 to rotate, and the rotating shaft 6 can drive the plurality of stirring blades 9 to rotate through the cooperation of the mounting sleeve 8, so that the plurality of stirring blades 9 can stir and mix the silver halide solvent and the developer, thereby obtaining the developer containing the silver halide solvent.
