In addition, the coating head does not need to be disassembled and carried, so that the leakage of the coating solution is avoided, and the environmental protection cost is reduced. Another core of the present utility model is to provide a coating apparatus.
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The coating head cleaning-in-place apparatus in the present utility model includes a cleaning housing 1, the cleaning housing 1 including a first housing 11 and a second housing 12. The upper part of the first housing 11 and the upper part of the second housing 12 are both hinged to the coating frame. The first housing 11 and the second housing 12 are rotatable in opposite directions to enclose a closed cavity. During the rotation of the first housing 11 and the second housing 12 in opposite directions, the first housing 11 and the second housing 12 gradually form a containment for the coating head 2, and finally the coating head 2 is contained in the closed cavity. The first housing 11 and the second housing 12 are also rotatable back to open so as to expose the coating head 2. The cleaning shell 1 is provided with a cleaning liquid injection port through which cleaning liquid is injected into the closed cavity of the cleaning shell 1. The cleaning shell 1 further comprises a cleaning liquid outlet 8, and the cleaning liquid in the cleaning shell 1 can be discharged through the cleaning liquid outlet 8.
In the present utility model, if it is necessary to wash the coating head 2, the first housing 11 and the second housing 12 are controlled to be turned toward each other to be closed, so that the coating head 2 is in the closed chamber. And then injecting cleaning liquid into the closed cavity of the cleaning shell through the cleaning liquid injection port, so that the coating head 2 can be cleaned. After the cleaning is finished, the cleaning liquid is discharged through the cleaning liquid outlet 8, and then the first shell 11 and the second shell 12 are controlled to rotate back to open so as to expose the coating head 2, so that the coating head 2 can perform coating operation.
In the utility model, the coating head 2 does not need to be detached from the coating frame, and the coating head 2 does not need to be reinstalled after the cleaning is finished, thereby improving the operation efficiency of coating equipment and being beneficial to the mass production of film products. In addition, since there is no need to disassemble and carry the coating head 2, leakage of the coating solution is avoided, thereby reducing the environmental cost.
In the utility model, the rotation of the first shell 11 and the second shell 12 can be driven by two cylinders, and when the first shell 11 and the second shell 12 are opened or closed in place, the two cylinders are controlled to be self-locking, so that the cleaning shell 1 is kept in an opened or closed state. The rotation of the first housing 11 and the second housing 12 can also be driven manually, and the first housing 11 and the second housing 12 are locked by bolts after the cleaning housing 1 is closed in place. The first housing 11 and the second housing 12 are connected to the coating frame by a connector when the cleaning housing 1 is opened in place. The opening and closing manners of the first housing 11 and the second housing 12 are not particularly limited herein, as long as the first housing 11 and the second housing 12 can be driven to be opened and closed while the opened and closed states of the first housing 11 and the second housing 12 can be maintained, and all fall within the scope of protection herein.
When the coating head 2 is not in operation, the coating head 2 is in a high position, and a certain distance is reserved between the coating head 2 and the coating platform, so that the coating platform cannot interfere with the closing of the cleaning shell 1. When the cleaning housing 1 is opened, the lowest parts of the first housing 11 and the second housing 12 are higher than the coating head 2, so that the first housing 11 and the second housing 12 do not contact the film on the coating platform during the coating operation of the coating head 2, thereby ensuring the smooth proceeding of the coating operation.
In order to ensure that there is sufficient coating solution during the coating operation, a specific embodiment of the utility model provides a reservoir 3 in the upper part of the coating head 2. The liquid storage tank 3 is communicated with the coating head 2. The reservoir 3 is used for storing the coating solution. The liquid tank 3 continuously feeds the coating solution to the coating head 2 when the coating head 2 performs a coating operation. This embodiment defines that when the first housing 11 and the second housing 12 are closed, the applicator head 2 and the reservoir 3 are simultaneously enclosed in the closed chamber. So that both the reservoir 3 and the applicator head 2 can be cleaned.
In the embodiment of the present utility model, the cleaning liquid filling port is provided at the upper portion of the cleaning housing 1. A cleaning liquid injection pipe 4 is arranged in the cleaning liquid injection port in a penetrating way. The cleaning liquid filling pipe 4 comprises a base pipe and a telescopic pipe. The telescopic tube is movably connected in the base tube. The liquid storage tank 3 is provided with a via hole for the telescopic pipe to pass through. The telescopic tube may extend from the base tube and through the via hole into the reservoir 3. The telescopic tube can also be contracted into the base tube to come out of the liquid storage tank 3 and be directly communicated with the closed cavity of the cleaning shell 1.
If the coating solution required for the next coating is the same as the coating solution of the previous coating, the outer surfaces of the coating head 2 and the liquid tank 3 need only be cleaned when the coating head 2 is cleaned after the previous coating operation is completed. Then the extension tube of the cleaning liquid filling tube 4 is contracted into the base tube to be directly communicated with the closed cavity of the cleaning shell 1, and the via hole on the liquid storage tank 3 is plugged. The cleaning liquid thus introduced into the closed chamber through the cleaning liquid filling pipe 4 submerges the coating head 2 and the liquid storage tank 3 to clean the outer surfaces of the coating head 2 and the liquid storage tank 3.
If the coating solution required for the next coating is different from the previous coating solution, it is necessary to clean the outside and inside of the coating head 2 and the tank 3 when the coating head 2 is cleaned after the previous coating operation is completed. The extension tube of the cleaning liquid filling tube 4 then extends out of the base tube and into the liquid reservoir 3 through the via hole in the liquid reservoir 3. Thus, the cleaning liquid can be injected into the liquid storage tank 3 through the cleaning liquid injection pipe 4. When the liquid storage tank 3 is filled with cleaning liquid, the coating frame can be controlled to perform empty coating operation, so that the cleaning liquid in the liquid storage tank 3 flows out from the coating head 2, and the inside of the coating head 2 is cleaned. With the continuous injection of the cleaning liquid, the cleaning liquid overflows into the closed cavity of the cleaning housing 1 through the through hole on the liquid storage tank 3, and finally submerges the coating head 2 and the liquid storage tank 3 to clean the outside of the coating head 2 and the liquid storage tank 3.
The movable connection of the base pipe and the telescopic pipe can be realized by the following modes: the base pipe and the telescopic pipe are arranged in a threaded connection mode, and when the telescopic pipe is screwed in one direction, the telescopic pipe can shrink into the base pipe. When the telescopic tube is screwed in the other direction, the telescopic tube protrudes from the base tube. The movable connection of the base pipe and the telescopic pipe can also be realized by the following modes: two spring buckles arranged along the radial direction are arranged on the telescopic pipe, and buckling holes which are clamped with the spring buckles are arranged on the base pipe. An upper group of buckling holes and a lower group of buckling holes are arranged along the axial direction of the base pipe, and each group of buckling holes comprises two buckling holes which are arranged along the radial direction of the base pipe. After the telescopic pipe is contracted into the base pipe, the two spring buckles on the telescopic pipe can respectively spring into the two buckle holes above. When the telescopic pipe extends out of the base pipe, the two spring buckles on the telescopic pipe can respectively spring into the two buckling holes below. The movable connection mode of the base pipe and the telescopic pipe is not particularly limited herein, as long as the telescopic operation of the cleaning liquid filling pipe 4 can be realized, and the telescopic operation falls into the protection scope herein.
In order to improve the cleaning effect, the ultrasonic generator 5 is arranged on the inner wall of the cleaning shell 1, and the ultrasonic generator 5 can force the coating solution on the wall surfaces of the coating head 2 and the liquid storage tank 3 to be dissolved into the cleaning liquid.

In order to facilitate the discharge of the cleaning liquid, in the embodiment of the utility model, the bottom of the cleaning housing 1 is provided with a cone shape which is concave downwards, and the cleaning liquid outlet 8 is arranged at the lower position of the bottom of the cleaning liquid housing. In this way, the cleaning liquid automatically gathers in the lower part of the cleaning housing 1 and is discharged through the cleaning liquid outlet 8.
During cleaning operation, the cleaning liquid outlet 8 is in a closed state; when the cleaning liquid is discharged, the cleaning liquid outlet 8 is opened. In order to facilitate control of the cleaning liquid outlet 8, the specific embodiment of the utility model is provided with a control valve in the cleaning liquid outlet 8, and the opening and closing of the cleaning liquid outlet 8 is realized by controlling the control valve. In addition, for convenience of installation, the cleaning liquid outlet 8 may be provided in either one of the first casing 11 or the second casing 12.
In order to facilitate the feeding of the coating solution into the reservoir 3, a coating solution injection tube 7 is provided in a specific embodiment of the present utility model. The coating liquid injection pipe 7 is positioned at the upper part of the liquid storage tank 3, and the coating liquid injection pipe 7 is communicated with the liquid storage tank 3.
