Description

Technical Field

[0001] This utility model relates to the technical field of coating machine equipment, and more specifically to an improved liquid adsorption structure for the curtain edge roller surface. Background Technology

[0002] In the coating industry, during the coating process, the coating is applied to the roller surface in the previous step. The coating covers the width of the roller, and the area covered on both sides must be larger than the width of the product to be processed to avoid missed coating at the edges. However, this results in waste of excess coating liquid on both sides. Therefore, it is necessary to set up a liquid collection structure on the roller surface at the edge of the roller to meet the liquid control requirements on both sides of the roller surface. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an improved liquid adsorption structure for the curtain edge roller surface, which improves the adsorption force of liquid and enhances the liquid collection effect through the shape design of the cavity.

[0004] This utility model provides the following technical solution: an improved liquid adsorption structure for the side roller surface, including a support, a flow channel for liquid flow is provided inside the support, an intake port for adsorbing liquid is provided at the lower front side of the support, the flow channel is connected to the intake port, the flow channel extends backward from the intake port to form an enlarged bucket-shaped structure, and the rear end of the bucket-shaped structure is connected to an externally penetrating liquid outlet.

[0005] As an improvement, the size of the inlet is adjusted by using a removable pad.

[0006] As an improvement, the middle section of the flow channel is also connected to an externally accessible cleaning channel.

[0007] As an improvement, the cleaning channels are symmetrically arranged on both sides of the middle section of the flow channel.

[0008] As an improvement, the flow channel is flat, with the inlet and outlet located on the central axis of the flow channel, and the cleaning channel is offset from the central axis of the flow channel and symmetrically arranged on both sides.

[0009] As an improvement, the support includes a front frame and a rear frame. The outlet and cleaning channel are machined on the rear frame, and the front frame and the rear frame are installed together to form the suction port and the flow channel.

[0010] The beneficial effects of this utility model are: by utilizing the narrow opening of the suction inlet, pressure is generated when the liquid is adsorbed, and combined with the funnel-shaped design of the flow channel, sufficient liquid adsorption force is formed to improve the control effect of the liquid on the roller surface.

[0015] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0016] like Figure 1 , 2 Figures 3 and 4 show specific embodiments of the improved liquid adsorption structure of the curtain edge roller surface of this utility model. This embodiment includes a support 1, in which a flow channel 3 for liquid flow is provided. A suction port 2 for adsorbing liquid is provided at the lower front side of the support 1. The flow channel 3 is connected to the suction port 2. The flow channel 3 extends backward from the suction port 2 to form an enlarged funnel-shaped structure. The rear end of the funnel-shaped structure is connected to an externally penetrating liquid outlet 4.

[0017] In use, two sets of liquid adsorption structures are installed symmetrically on both sides of roller surface B, close to roller surface B. The spacing between the two sets of liquid adsorption structures is adjusted according to the width requirements of the liquid surface. The liquid adsorption structures then adsorb the liquid A on both sides of roller surface B, resulting in a smooth liquid edge between the two sets of adsorption structures. As an improvement in structure, the suction port 2 has a narrow opening. When the liquid outlet 4 connects to the external power mechanism and adsorbs liquid, the liquid entering the suction port 2 is pressurized due to the narrow opening. After being pressurized and accelerated, it flows towards the subsequent funnel-shaped flow channel 3. Driven by this adsorption force, the liquid flows along the flow channel 3 to the liquid outlet 4 and reaches the connected collection chamber for collection. The structural design provides better adsorption force at the suction port 2, ensuring that the liquid on the roller surface B is fully adsorbed, avoiding intermittent adsorption, ensuring the smoothness of the liquid edge on the roller surface A, ensuring effective control of the liquid on the roller surface, and ensuring the processing quality of the product.

[0018] As an improved implementation, the size of the inlet 2 is adjusted by setting a removable gasket.

[0019] In practical implementation, the thickness of the gasket can be selected as needed, and then the gasket can be limited at the suction port 2 by means of existing slot snap-fit ​​structure, fastener locking structure, etc., so as to flexibly change the diameter of the suction port 2, and thus flexibly change the adsorption pressure to achieve the desired liquid adsorption effect.

[0020] As an improved specific implementation, the middle section of the flow channel 3 is also connected to an externally penetrating cleaning channel 5.

[0021] like Figure 1 , 4 As shown, for cleaning the flow channel 3, due to its special structure and the fact that the liquid is a colloid with a certain viscosity, conventional inlet and outlet rinsing methods are generally ineffective. Furthermore, the narrow design of the suction inlet 2 also hinders efficient rinsing. By setting a cleaning channel 5 in the middle section of the flow channel 3, and sealing the opening of the cleaning channel 5 during equipment use, the liquid flows along the direction of the suction inlet 2, the flow channel 3, and the outlet 4 (e.g., ...). Figure 2 As shown), it will not enter the cleaning channel 5. When the equipment is removed for cleaning, the cleaning channel 5 is opened and the cleaning fluid is connected. The cleaning fluid will flow along the cleaning channel 5 to the flow channel 3, and then a portion will flow out from the suction port 2 (as shown). Figure 4 As shown in the figure, a portion flows out from outlet 4, thus achieving a better cleaning effect.

[0022] As a preferred option, such as Figure 1 As shown, the cleaning channels 5 are symmetrically arranged on both sides of the middle section of the flow channel 3. This allows the cleaning liquid to enter evenly from both sides during cleaning, ensuring that the cleaning liquid is thoroughly and completely flushed into the entire space of the flow channel 3 from both sides, reducing the possibility of dead corners not being flushed.

[0023] As a preferred option, such as Figure 1 , 2 As shown, the flow channel 3 is flat, with the inlet 2 and outlet 4 located at the central axis of the flow channel 3. The cleaning channels 5 are symmetrically arranged on both sides, offset from the central axis of the flow channel 3. When the liquid flows through the inlet 2, flow channel 3, and outlet 4, it flows along the central axis in the direction of adsorption, reducing the possibility of it flowing into the cleaning channels 5 on both sides. During cleaning, the cleaning liquid is flushed in from both sides offset from the central axis of the flow channel 3, thoroughly mixing and rinsing the flow channel 3 in both directions, achieving a good cleaning effect.

[0024] As an improved specific implementation, the support 1 includes a front frame 11 and a rear frame 12. The liquid outlet 4 and the cleaning channel 5 are machined and formed on the rear frame 12. The front frame 11 and the rear frame 12 are fitted together to form the suction port 2 and the flow channel 3.

[0025] like Figure 1 , 2 As shown in Figure 4, the outlet 4 and cleaning channel 5 are normal pipe structures, which are separately machined on the rear frame 12. The suction port 2 and flow channel 3 are spaces formed by slots dug in the end faces of the front frame 11 and / or the rear frame 12. Then, the front frame 11 and the rear frame 12 are assembled at the slotted position to enclose the slot, thus forming a complete suction port 2 and flow channel 3 structure. This structural design facilitates the machining of irregularly shaped suction ports 2 and flow channels 3, and also facilitates disassembly and maintenance during shutdown.

[0026] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
