[0004] The purpose of this invention is to provide a structure for switching between coating blade components, thereby solving the problems of complex processes and low efficiency when switching between two different types of blades in the prior art.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A coating blade assembly switching structure includes a coating blade assembly and a base. The base has a first opening and a second opening opposite to each other. A sliding guide rail extending from one side of the first opening to one side of the second opening is installed at intervals on the base. A rotary bearing assembly is slidably installed on the sliding guide rail, and the coating blade assembly is mounted on the rotary bearing assembly. The base has two first fixing plates located on one side of the first opening and two second fixing plates located on one side of the second opening. The coating blade assembly has a limiting step for cooperating with the first or second fixing plates, and fasteners lock the first or second fixing plates onto the limiting step.

[0008] Preferably, the rotary bearing assembly includes a sliding plate and a bearing housing fixed on the sliding plate, a rotary bearing is mounted on the bearing housing, a connecting plate is mounted on the rotary bearing, and the coating blade assembly is mounted on the connecting plate.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] See Figures 1-5 As shown in the embodiment of this utility model, a coating doctor blade assembly switching structure is proposed, including a coating doctor blade assembly 2 and a machine base 1. The machine base 1 is the main load-bearing part in the coating machine, and the coating doctor blade assembly 2 cooperates with the steel roller to realize the coating process by switching the angle. Generally speaking, the gravure forward coating doctor blade 22 state and the micro-gravure reverse coating doctor blade 22 state can realize different coating processes. Specifically, a first opening 101 and a second opening 102 are provided opposite to each other on the base 1. A sliding guide rail 3 is installed on the base 1 at intervals, extending from one side of the first opening 101 to the other side of the second opening 102. A rotating shaft 213 bearing assembly is slidably installed on the sliding guide rail 3. The coating blade assembly 2 is installed on the rotating shaft 213 bearing assembly, so that the coating blade assembly 2 can be rotated and adjusted on the rotating shaft 213 bearing assembly and move along the sliding guide rail 3 between the first opening 101 and the second opening 102 following the rotating shaft 213 bearing assembly. At the same time, two first fixing plates 5 are provided on the base 1 on one side of the first opening 101, and two second fixing plates 6 are provided on one side of the second opening 102. When the coating blade assembly 2 is in the position of the first opening 101, it is fixed by the first fixing plates 5, which is the state of micro-concave reverse coating blade 22. When the coating blade assembly 2 is in the position of the second opening 102, it is fixed by the second fixing plates 6, which is the state of concave forward coating blade 22.

[0025] When switching between operating states, it is only necessary to rotate and move the coating blade assembly 2 and then fix it on the corresponding first fixing plate 5 or second fixing plate 6. There is no need to disassemble and reassemble, which improves the convenience and efficiency of switching.

[0026] Meanwhile, the coating blade assembly 2 is provided with a limiting step 20 for cooperating with the first fixing plate 5 or the second fixing plate 6. Fasteners lock the first fixing plate 5 or the second fixing plate 6 onto the limiting step 20. The positioning function of the limiting step 20 enables the positioning of the first fixing plate 5 or the second fixing plate 6, thereby improving the efficiency of the locking process. The base 1 has a first mounting groove 103 for mounting the first fixing plate 5 and a second mounting groove 104 for mounting the second fixing plate 6. The first mounting groove 103 limits the installation position of the first fixing plate 5, and the second mounting groove 104 limits the installation position of the second fixing plate 6, thereby enabling preliminary positioning of the first fixing plate 5 and the second fixing plate 6, facilitating precise positioning after adjustment of the coating blade assembly 2.

[0027] The rotating shaft 213 bearing assembly serves both a load-bearing function and a function of rotating the coating blade assembly 2. The rotating shaft 213 bearing assembly includes a sliding plate 41 and a bearing seat 42 fixed on the sliding plate 41. The rotating shaft 213 bearing is mounted on the bearing seat 42, and a connecting plate 43 is mounted on the rotating shaft 213 bearing. The coating blade assembly 2 is mounted on the connecting plate 43 and connected to the sliding guide rail 3 via the sliding plate 41. The connecting plate 43 is connected to the rotating shaft 213 bearing, thereby ensuring that the rotating shaft 213 bearing can rotate stably and bear load under the connected state.

[0028] After the coating blade assembly 2 rotates and moves, the coating angle needs to be adjusted according to the corresponding coating requirements. Specifically, the coating blade assembly 2 includes an adjustment mechanism 21 mounted on the rotating shaft 213 bearing assembly and a coating blade 22 rotatably mounted on the adjustment mechanism 21. An angle adjustment cylinder 23 is rotatably mounted on the adjustment mechanism 21. The telescopic rod of the angle adjustment cylinder 23 is rotatably connected to the coating blade 22. The angle adjustment is achieved by pushing or pulling the coating blade 22 relative to the adjustment mechanism 21 to adjust the angle, so as to adapt to the coating state after the entire coating blade assembly 2 has turned and moved.

[0029] The adjustment mechanism 21 can adjust the relative position of the coating blade 22 according to the coating width. Specifically, the adjustment mechanism 21 includes a fixed base 211 and an adjustment plate 212 slidably mounted on the fixed base 211. A rotating shaft 213 is mounted on the adjustment plate 212, and the coating blade 22 is rotatably mounted on the rotating shaft 213. An adjustment screw mechanism 214 for adjusting the lateral movement of the adjustment plate 212 is provided on the fixed base 211. At the same time, a drive mechanism for driving the adjustment screw mechanism 214 is provided on the fixed base 211. The adjustment plate 212 is displaced relative to the fixed base 211 by driving the adjustment screw mechanism 214 through the drive mechanism, thereby realizing the adjustment of the relative position of the coating blade 22 to adapt to the coating width adjustment.

[0030] The driving mechanism includes a rotating disk 215 rotatably mounted on the fixed base 211. One end of the rotating disk 215 extending into the rotating base is connected to a first bevel gear 216. The adjusting screw mechanism 214 includes a second bevel gear 217 that meshes with the first bevel gear 216. When the rotating disk 215 rotates, the meshing action of the first bevel gear 216 and the second bevel gear 217 converts the rotation of the rotating disk 215 into the action of the adjusting screw mechanism 214, thereby achieving control outside the fixed base 211. After the adjustment of the lead screw mechanism 214 is completed, the action state of the lead screw mechanism 214 needs to be locked. Specifically, a brake gear 218 is provided in the lead screw mechanism 214 at intervals. The fixed seat 211 is provided with a locking disc 219 that can be screwed into and abut against the brake gear 218. The depth of the inserted part is adjusted by rotating the locking disc 219 until it abuts against the brake gear 218 and forms a lock, thereby locking the relative rotation action of the lead screw mechanism 214.
