The drawings of the present invention are for illustrative purposes only and are not drawn to scale. The following embodiments are further detailed to explain the technical matters related to the present invention, but the disclosure is not intended to limit the scope of the present invention.
It will be understood that, although the terms "first," "second," "third," etc. may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one element from another element, or from one signal to another signal. In addition, the term "or" as used herein should be taken to include any one or combination of more of the associated listed items as the case may be.
Please refer to fig. 1 to 7, which illustrate an embodiment of the present invention. As shown in fig. 1, the present embodiment discloses a wet coating apparatus 100, which includes a coating device 1 and a feeding device 2 connected to the coating device 1, and the coating device 1 is detachably mounted on the feeding device 2. It is particularly emphasized that the wet coating apparatus 100 is different from the dry coating apparatus in this embodiment.
It should be noted that the wet coating apparatus 100 is illustrated by using the coating device 1 and the feeding device 2 in the embodiment, but the invention is not limited thereto. For example, in other embodiments not shown in the present disclosure, the coating device 1 may be used alone (for example, sold) or may be used with other feeding devices different from those of the present embodiment; alternatively, the feeding device 2 may be used alone (e.g., vending) or with other devices. The specific configurations of the coating device 1 and the feeding device 2 will be described first, and then the connection relationship between the two will be described in due course.
As shown in fig. 1 to 3, the coating apparatus 1 includes a housing 11 and a plurality of coating heads 12 mounted on the housing 11. Wherein a plurality of magazines 112 independent of each other are formed inside the housing 11, and the plurality of magazines 112 of the housing 11 are preferably independent of each other and not communicated with each other.
In more detail, the housing 11 in this embodiment includes two plates 111 joined to each other, and each of the plates 111 is preferably flat. A plurality of receiving grooves 1111 are formed in each plate body 111, so that the receiving grooves 1111 of any one plate body 111 are respectively connected to the receiving grooves 1111 of another plate body 111, thereby forming a plurality of storage spaces 112. That is, any two of the receiving grooves 1111 facing each other and belonging to different plate bodies 111 jointly surround and form one of the storage spaces 112.
Further, the housing 11 is formed with a plurality of through holes 1112 communicating with a plurality of the stock spaces 112, respectively, and each of the stock spaces 112 may communicate with at least one of the through holes 1112, but the present invention is not limited thereto. In the present embodiment, a plurality of through holes 1112 are formed in at least one of the two plate bodies 111, and the through holes 1112 are preferably located at the same level (e.g., the through holes 1112 are spaced apart from an edge of the corresponding plate body 111 by the same distance).
Furthermore, each of the coating heads 12 is detachably inserted into the housing 11 and partially protrudes from the housing 11, and the partial portions of the coating heads 12 are preferably flush with each other so as to facilitate coating in a coating operation of a plate material (not shown). One of the coating heads 12 is disposed in each of the storage spaces 112, so that each coating head 12 can receive or store a coating material M (e.g., a glue) without interruption, but the invention is not limited thereto.
In more detail, the coating heads 12 are clamped and fixed between the two plate bodies 111 in the embodiment, and the coating heads 12 preferably have substantially the same structure. Wherein each coating head 12 can take the coating material M from the corresponding through hole 1112.
It should be noted that the coating material M is stored and transported by the coating head 12, so that a wide range of viscosity (e.g., 10cps to 100 cps) can be covered, thereby facilitating the expansion of the application range of the coating apparatus 1 (or the wet coating device 100).
Further, each of the coating heads 12 has a porous structure having compressive elasticity so as to be able to accumulate the coating material M and to transfer the accumulated coating material M to the sheet material during the coating operation. In the process of transferring the coating material M, the coating head 12 may transfer the coating material M by contacting or non-contacting the plate, and the invention is not limited herein.
It should be noted that, in the present embodiment, the coating apparatus 1 is described as including a plurality of coating heads 12 having substantially the same structure and detachably inserted into the housing 11, but the invention is not limited thereto. For example, in other embodiments not shown in the present disclosure, the number of the coating heads 12 included in the capillary coating apparatus 1 may be at least one (that is, at least one coating head 12 is inserted into the plurality of storage spaces 112 of the housing 11); alternatively, at least one of the coating heads 12 of the plurality of coating heads 12 is non-detachably fixed to the housing 11.
As described above, in the coating apparatus 1 of the present embodiment, the coating material M is continuously injected into the coating head 12, so that the coating apparatus 1 not only can achieve precise coating, but also can adopt the coating material M with a wide viscosity coverage, thereby greatly expanding the application range of the coating apparatus 1.
Further, when the wet coating apparatus 100 performs the coating operation so that the coating heads 12 continuously output the coating material M, the feeding device 2 can be used to maintain the material content of each coating head 12, so that the coating device 1 can realize stable coating for a longer time by being matched with the feeding device 2 in the embodiment.
Wherein the feeding device 2 is connected to the plurality of through holes 1112 of the housing 11, and the feeding device 2 can be used for simultaneously injecting the coating material M from the plurality of through holes 1112 to the plurality of coating heads 12. In the embodiment, the feeding device 2 includes a switching mechanism 21, a storage mechanism 22 (e.g. a storage barrel) for storing the coating material M, and a feeding mechanism 23, and the coating device 1, the storage mechanism 22, and the feeding mechanism 23 can be connected or connected to the switching mechanism 21 (via a transmission pipe).
It should be noted that, as shown in fig. 1, fig. 2, and fig. 4, the feeding device 2 is described in this embodiment by using the switching mechanism 21 to cooperate with the coating device 1, the storing mechanism 22, and the feeding mechanism 23, but the invention is not limited thereto. For example, in other embodiments not shown in the present disclosure, the switching mechanism 21 can be used alone (e.g., vending) or with other devices. The specific structure of each mechanism of the feeding device 2 will be explained first, and then the connection relationship between each mechanism will be explained in due time.
In the present embodiment, the switching mechanism 21 includes a plurality of distribution pipelines 211, a plurality of linkage members 212 respectively connected to the distribution pipelines 211, a synchronization member 213 linked to the linkage members 212, and a driving cylinder 214 connected to the synchronization member 213, but the present invention is not limited thereto. For example, in other embodiments not shown in the present disclosure, the driving cylinder 214 may be replaced by other driving methods.
Each of the distribution pipes 211 has a feeding port 2113, a mixing port 2114, and a discharging port 2115, and the specific structure of any one of the distribution pipes 211 can be adjusted and changed according to design requirements, which is not limited herein. In this embodiment, a plurality of the distribution pipes 211 may have substantially the same structure, and each of the distribution pipes 211 includes a three-way valve tube 2111 and a switching member 2112 rotatably installed in the three-way valve tube 2111.
In each distribution pipe 211, the three-way valve tube 2111 is formed with the inlet 2113, the blending port 2114, and the outlet 2115, and the switching member 2112 can rotate to selectively communicate the blending port 2114 of the three-way valve tube 2111 with one of the inlet 2113 and the outlet 2115. Further, the switching member 2112 can rotate to make the mixing port 2114 of the three-way valve tube 2111 communicate with the feeding port 2113 only, so as to make the dispensing line 211 in a feeding state; alternatively, the switching member 2112 can be rotated to connect the dispensing port 2114 of the three-way valve tube 2111 to the discharge port 2115 only, so as to place the dispensing line 211 in a discharge state.
Each of the linkage members 212 can be used to adjust the connected distribution pipeline 211 between the feeding state (see fig. 5) and the discharging state (see fig. 6). In this embodiment, each of the linking members 212 is connected to the switching member 2112 of the corresponding distribution pipeline 211 and can rotate synchronously, so that the corresponding distribution pipeline 211 is in one of the feeding state and the discharging state.
Furthermore, as shown in fig. 1, fig. 2, and fig. 4 to fig. 7, the synchronizing member 213 can drive the plurality of linking members 212 to move synchronously, so that the plurality of distribution pipes 211 are all in one of the feeding state and the discharging state. In this embodiment, the driving cylinder 214 can be used to push the synchronizing member 213, so that the synchronizing member 213 can drive the plurality of linking members 212 to move synchronously. The driving cylinder 214 may be a hydraulic cylinder or a pneumatic cylinder, but the invention is not limited thereto.
In more detail, each of the linkage members 212 is further defined as a gear, and the synchronizing member 213 is defined as a rack engaged with the plurality of linkage members 212, and the synchronizing member 213 can move relative to the plurality of linkage members 212 to rotate the plurality of linkage members 212 synchronously. Accordingly, the distribution pipes 211, the linkage elements 212, and the synchronization elements 213 are mechanically coupled to achieve the effect of precise and synchronous feeding (e.g., the distribution pipes 211 can be synchronously in the discharging state), but the invention is not limited thereto. For example, in other embodiments not shown in the present invention, the switching mechanism 21 of the wet coating apparatus 100 may be implemented by an electronic component (e.g., a solenoid valve) instead under the condition of low requirement for feed synchronization.
In the above description of the structure of the switching mechanism 21, the connection relationship between the switching mechanism 21 and other components will be described below. The switching mechanism 21 is connected to the through holes 1112 of the coating apparatus 1 through the discharge ports 2115 of the plurality of distribution lines 211, the switching mechanism 21 is connected to the stock mechanism 22 through the feed ports 2113 of the plurality of distribution lines 211, and the switching mechanism 21 is connected to the feed mechanism 23 through the dispense ports 2114 of the plurality of distribution lines 211.
Further, as shown in fig. 1 and 5, when the plurality of dispensing lines 211 are all in the feeding state, the feeding mechanism 23 can be used to receive the coating material M from the stock mechanism 22 through the plurality of dispensing lines 211. Furthermore, as shown in fig. 1 and fig. 6, when the distribution pipes 211 are all in the discharging state, the feeding mechanism 23 can be used to synchronously output the coating material M therein to the coating apparatus 1 (or the discharge ports 2115 of the distribution pipes 211).
Accordingly, the switching mechanism 21 can be used for switching at different coating time points; for example, when the wet coating apparatus 100 is performing the coating operation, the switching mechanism 21 switches the coating material M to flow from the feeding mechanism 23 to the coating device 1; when the paint M in the supply mechanism 23 is used up and needs to be replenished, the switching mechanism 21 switches to allow the paint M in the stock mechanism 22 to flow to the supply mechanism 23, and the supply mechanism 23 can eliminate air bubbles in the paint M by the structural design relative to the stock mechanism 22.
The feeding mechanism 23 is preferably implemented by combining the following mechanisms to effectively control the amount of the material output to the switching mechanism 21, but the invention is not limited thereto. More specifically, the feeding mechanism 23 in this embodiment comprises a plurality of plungers 231 and a driver 232 (e.g., a motor) connected to the plurality of plungers 231. The plurality of plungers 231 have substantially the same structure and the number thereof may be equal to the number of the plurality of dispensing ports 2114, but the invention is not limited thereto.
Each of the plungers 231 has a tube body 2311, a push rod 2312 inserted into the tube body 2311, and an exhaust valve port 2313 located higher than the magazine 22, and each of the push rods 2312 is relatively movable along the tube body 2311. In each of the plungers 231, the push rod 2312 is hollow and is communicated with the tube body 2311 and the exhaust valve port 2313, and when the exhaust valve port 2313 is at an open position (as shown in fig. 1 and 5, the corresponding dispensing line 211 is preferably at the charging state), bubbles existing in the plungers 231 can be discharged out through the exhaust valve port 2313, and when the exhaust valve port 2313 is at a closed position (as shown in fig. 1 and 6, the corresponding dispensing line 211 is preferably at the discharging state), the push rod 2312 can move relative to the tube body 2311 to output the coating M in the plungers 231.
Further, the tubes 2311 of the plungers 231 are connected to the dispensing ports 2114 of the dispensing lines 211 (e.g., the bottom of each tube 2311 is connected to one of the dispensing ports 2114) for receiving the coating material M from the storage mechanism 22. Furthermore, the driver 232 is connected to the push rods 2312 of the plurality of plungers 231, and the driver 232 can drive the push rods 2312 of the plurality of plungers 231 to synchronously move so as to synchronously output the coatings M therein.
Technical effects of embodiments of the present invention
In summary, the wet coating apparatus and the coating device according to the embodiments of the present invention inject the coating material into the coating head continuously, so that the coating device can not only achieve precise coating, but also adopt the coating material with a wide viscosity range, thereby greatly expanding the application range of the coating device (or the wet coating apparatus).
In addition, the feeding device and the switching mechanism thereof disclosed in the embodiments of the present invention achieve the effect of precise and synchronous feeding (for example, the plurality of distribution pipelines can be synchronously in the discharging state) by the mechanism cooperation among the plurality of distribution pipelines, the plurality of linkage parts, and the plurality of synchronization parts. Wherein, the switching mechanism can be used for different time points as the flow direction of the coating switches to use, for example: the switching of the switching mechanism can enable the coating to flow to the plurality of discharge ports from the feeding mechanism; alternatively, the switching mechanism may be switched to allow the coating material in the stock mechanism to flow to the supply mechanism.
The disclosure is only a preferred embodiment of the invention and is not intended to limit the scope of the invention, so that all equivalent technical changes made by using the contents of the specification and drawings are included in the scope of the invention.
