When producing through a preparation device, it is necessary to fully mix the preparation liquid with additives and then discharge it.

[0003] At present, although the mixing of the preparation liquid can be achieved through equipment, there is room for improvement in its mixing efficiency. It is not possible to achieve multiple mixing through the improvement of the structure by one electric component, and the adjustment of the mixing efficiency cannot be achieved. Moreover, when a blockage occurs during the discharge process, the cleaning is not convenient enough. Summary of the Invention

[0004] In view of this, the present invention provides an aqueous UV coating preparation device and its process, which solves the problems that although the mixing of the preparation liquid can be achieved through equipment at present, there is room for improvement in its mixing efficiency, it is not possible to achieve multiple mixing through the improvement of the structure by one electric component, the adjustment of the mixing efficiency cannot be achieved, and when a blockage occurs during the discharge process, the cleaning is not convenient enough.

[0005] The purpose and efficacy of an aqueous UV coating preparation device and its process of the present invention are achieved by the following specific technical means:

[0006] The present invention provides an aqueous UV coating preparation device and its process, which specifically includes: a box body;

[0007] The box body contains a preparation liquid, and a mixing component is installed on the box body; a cover plate is installed on the box body, and a feed pipe for feeding is arranged on the cover plate. Two support blocks for supporting the box body during placement are symmetrically fixed on the bottom end surface of the box body.

[0008] Further, the mixing component is composed of a rotating shaft, a motor and an impeller. The rotating shaft is rotatably connected to the box body, and a motor for driving the rotating shaft is installed on the box body; an impeller is installed on the rotating shaft, and the impeller is located inside the box body and contacts the preparation liquid. When it is necessary to mix the preparation liquid, the motor can be directly started. When the motor rotates, it can drive the rotating shaft and the impeller to rotate, and the mixing of the preparation liquid can be achieved through the rotation of the impeller.

[0009] Further, an auxiliary component is installed inside the box body. The auxiliary component is composed of a mounting block, a telescopic rod, and a mixing plate. There are two mounting blocks in total. The two mounting blocks are respectively welded to the left end face and the right end face of the inner wall of the box body. A telescopic rod is fixed to the bottom end face of each mounting block. One end of the lower part of the two telescopic rods is fixed to the mixing plate. The bottom end face of the mixing plate contacts the impeller. When the impeller rotates, the mixing plate moves up and down reciprocally. When the impeller rotates, it can drive the mixing plate to move up and down. When the mixing plate moves up and down, it can realize the re - mixing of the liquid prepared inside the box body, improving the mixing efficiency.

[0010] Further, an adjustment mechanism is installed on the cover plate. The adjustment mechanism is composed of a connecting block, an electric cylinder, a first locking screw, and a second locking screw. The connecting block is slidably connected to the cover plate. One end of the lower part of the connecting block is also fixed with an electric cylinder. One end of the lower part of the electric cylinder is fixed to the mixing plate.

[0011] Further, a first locking screw for locking the connecting block is threadedly connected to the cover plate. A second locking screw for locking the first locking screw is threadedly connected to the handle of the first locking screw. When it is necessary to improve the mixing effect, first pull the connecting block upward. At this time, the mixing plate is out of the rotation range of the impeller. Then tighten the first locking screw. At this time, the connecting block is locked by the first locking screw. Then tighten the second locking screw. At this time, the first locking screw can be locked by the second locking screw. Then control the electric cylinder to reciprocate. When the electric cylinder reciprocates, it can drive the mixing plate to move up and down greatly, and at this time, the mixing effect can be improved again.

[0012] Further, a discharge component is arranged on the box body. The discharge component is composed of a discharge pipe, an auxiliary pipe, a valve, and a connecting pipe. The discharge pipe is arranged on the box body and is used for discharging materials. An auxiliary pipe is connected to the discharge pipe. A valve is connected to the auxiliary pipe. A connecting pipe is connected to the valve. The connecting pipe is connected to the collection box.

[0013] Further, a filter screen is arranged at the connection between the discharge pipe and the box body. The auxiliary pipe is made of rubber and is a cleaning structure for the discharge pipe. When it is necessary to discharge, directly controlling the on - off of the valve can realize the on - off of the discharge. When the filter screen at the discharge pipe is blocked, since the auxiliary pipe is made of rubber, continuously squeezing the auxiliary pipe can realize the back - flow of the liquid in the auxiliary pipe. At this time, the filter screen at the discharge pipe can be cleaned by the back - flowing liquid.

[0014] Further, a gas mixing component is arranged on the box body. The gas mixing component is composed of an air inlet pipe, a sleeve, air injection holes, a gear, and a tooth row. The air inlet pipe is made of metal and is installed on the box body. The air inlet pipe is connected to an air supply pump.

[0015] Further, a sleeve is rotatably connected to the intake pipe. The sleeve is a cylindrical tubular structure, and annularly-arrayed air injection holes are formed in both the sleeve and the intake pipe.

[0016] Further, a gear is arranged on the sleeve, and a tooth row is welded to the bottom end face of the mixing plate. The tooth row meshes with the gear. When auxiliary mixing is required, the air pump is directly started. After the air pump is started, the gas will be ejected through the air injection holes to achieve auxiliary mixing. At the same time, when the mixing plate reciprocates up and down, the sleeve can be rotated through the meshing transmission between the tooth row and the gear. At this time, the air injection holes on the sleeve and the intake pipe are in an intermittent air jet state, and the mixing effect can be improved.

[0017] Further, the filter screen at the discharge pipe contacts the rightmost impeller. When the impeller rotates, the filter screen at the discharge pipe can be cleaned.

[0018] A production method of a water-based uv coating preparation device includes the following steps:

[0019] 01. Add an equivalent amount of photoinitiator into the box body. The photoinitiator is a high-functional hydroxyl-containing acrylate.

[0020] 02. Add organic amine and ionic compound B into the box body according to the weight percentage of 1:10.

[0021] 03. Start the motor. When the motor rotates, it can drive the rotating shaft and the impeller to rotate. Through the rotation of the impeller, the mixing of the preparation liquid can be achieved. When the impeller rotates, the mixing plate reciprocates up and down. When the impeller rotates, it can drive the mixing plate to move up and down. When the mixing plate moves up and down, the preparation liquid in the box body can be mixed again.

[0022] 04. Pull the connecting block upward. At this time, the mixing plate is separated from the rotation range of the impeller, and then tighten the first locking screw. At this time, the connecting block is locked through the first locking screw, and then tighten the second locking screw. At this time, the first locking screw can be locked through the second locking screw, and then control the electric cylinder to reciprocate. When the electric cylinder reciprocates, it can drive the mixing plate to move up and down greatly.

[0023] 05. The on-off of the discharge can be directly realized by controlling the on-off of the valve. When the filter screen at the discharge pipe is blocked, since the auxiliary pipe is made of rubber, continuously squeezing the auxiliary pipe can realize the reflux of the liquid in the auxiliary pipe. At this time, the filter screen at the discharge pipe can be cleaned through the refluxing liquid.

[0024] 06. Start the air pump. After the air pump starts, the gas will be ejected through the air injection holes to achieve auxiliary mixing. At the same time, when the mixing plate reciprocates up and down, the rotation of the sleeve can be achieved through the meshing transmission of the gear row and the gear. At this time, the air injection holes on the sleeve and the intake pipe are in an intermittent air jet state.

[0025] Beneficial effects

[0026] A mixing component and an auxiliary component are provided. During use, on the one hand, control the motor to rotate. When the motor rotates, it can drive the rotating shaft and the impeller to rotate. Through the rotation of the impeller, the mixing of the prepared liquid can be achieved.

[0027] On the other hand, when the impeller rotates, the mixing plate reciprocates up and down. When the impeller rotates, it can drive the mixing plate to move up and down. When the mixing plate moves up and down, the re-mixing of the prepared liquid in the box can be achieved, improving the mixing efficiency. Through the rotation of the motor, double mixing can be achieved. Through double mixing, the mixing efficiency can be improved. After the mixing efficiency is improved, the preparation time can be greatly shortened, thereby improving the overall preparation efficiency, with high practicality.

[0028] Through the setting of the adjustment mechanism, when it is necessary to mix the prepared liquid, directly start the motor; when it is necessary to improve the mixing effect, first pull the connecting block upward. At this time, the mixing plate is out of the rotation range of the impeller, and then tighten the first locking screw. At this time, the locking of the connecting block is achieved through the first locking screw, and then tighten the second locking screw. At this time, the locking of the first locking screw can be completed through the second locking screw, and then control the electric cylinder to reciprocate. When the electric cylinder reciprocates, it can drive the mixing plate to move up and down significantly, and at this time, the mixing effect can be improved again, with high practicality.

[0029] Through the setting of the discharge component, when it is necessary to discharge, directly control the on-off of the valve to achieve the on-off of the discharge. When the filter screen at the discharge pipe is blocked, since the auxiliary pipe is made of rubber, continuously squeezing the auxiliary pipe can achieve the reflux of the liquid in the auxiliary pipe. At this time, the filter screen at the discharge pipe can be cleaned through the refluxed liquid, with high practicality.

[0030] Through the gas mixing component, on the one hand, directly start the air pump. After the air pump starts, the gas will be ejected through the air injection holes to achieve auxiliary mixing.

[0031] On the other hand, when the mixing plate reciprocates up and down, the rotation of the sleeve can be achieved through the meshing transmission of the gear row and the gear. At this time, the air injection holes on the sleeve and the intake pipe are in an intermittent air jet state, and at this time, the mixing effect can be improved; when the impeller rotates, the filter screen at the discharge pipe can be cleaned, improving the mixing effect, and there is no need to manually clean the filter screen, with a reasonable structure.

8. A preparation method of an aqueous UV coating, characterized in that, Using the waterborne uv coating preparation equipment described in claim 7, the following steps are included:

01. Add an equivalent amount of photoinitiator into the box body (1). The photoinitiator is a high-functional hydroxyl-containing acrylate.

02. Add organic amine and ionic compound B into the box body (1) according to the weight percentage of 1:

10.

03. Start the motor (202). When the motor (202) rotates, it can drive the rotating shaft (201) and the impeller (203) to rotate. The mixing of the preparation liquid can be realized by the rotation of the impeller (203). When the impeller (203) rotates, the mixing plate (303) moves up and down reciprocally. When the impeller (203) rotates, it can drive the mixing plate (303) to move up and down. When the mixing plate (303) moves up and down, the re-mixing of the preparation liquid in the box body (1) can be realized.

04. Pull the connecting block (401) upward. At this time, the mixing plate (303) is out of the rotation range of the impeller (203). Then tighten the first locking screw (403). At this time, the locking of the connecting block (401) is realized through the first locking screw (403). Then tighten the second locking screw (404). At this time, the locking of the first locking screw (403) can be completed through the second locking screw (404). Then control the reciprocating telescoping of the electric cylinder (402). When the electric cylinder (402) reciprocates telescopically, it can drive the mixing plate (303) to move up and down greatly.

05. The on-off of the discharge can be directly realized by controlling the on-off of the valve (503). When the filter screen at the discharge pipe (501) is blocked, since the auxiliary pipe (502) is made of rubber, continuously squeezing the auxiliary pipe (502) can realize the reflux of the liquid in the auxiliary pipe (502). At this time, the filter screen at the discharge pipe (501) can be cleaned by the refluxed liquid.

06. Start the air pump. After the air pump starts, the gas will be ejected through the air injection holes (603) to achieve auxiliary mixing. At the same time, when the mixing plate (303) reciprocates up and down, the rotation of the sleeve (602) can be achieved through the meshing transmission of the gear row (605) and the gear (604). At this time, the air injection holes (603) on the sleeve (602) and the intake pipe (601) are in an intermittent air injection state.
