Description

Technical Field

[0001] This utility model belongs to the field of surface treatment technology, and more specifically, it relates to a double-sided transfer coating structure. Background Technology

[0002] Double-sided transfer coating, as a cutting-edge coating technology, primarily functions to simultaneously or sequentially coat both sides of a transfer film with special functional coatings, thereby modifying the surface of the transfer film. Compared to traditional single-sided coating processes, simultaneous double-sided coating cleverly eliminates the cumbersome step of flipping the transfer film after single-sided coating for the other side, greatly shortening the production cycle and significantly improving production efficiency. Today, in rapidly growing fields such as new energy materials and optical thin films, double-sided coating technology is gaining widespread application due to its unique advantages.

[0003] Based on the above, a prominent problem exists in the current double-sided coating structure used for coating operations: during the coating process, the coating liquid cannot be fully and completely absorbed by the transfer membrane; the unabsorbed coating liquid often drips directly due to the lack of an effective guidance and collection mechanism. This not only makes it difficult to conveniently recycle and reuse these coating liquids, but also causes a large amount of material waste in the long run, increasing production costs and hindering the efficient use of resources and sustainable production. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a double-sided transfer coating structure to solve the problem that existing coating structures cannot recycle coating liquid, resulting in resource waste.

[0005] This utility model provides a double-sided transfer coating structure, achieved through the following specific technical means:

[0006] A double-sided transfer coating structure includes a driving mechanism and a circulation mechanism. The driving mechanism includes a fixed support, which consists of a horizontal plate and two vertical plates on both sides. Two sets of ball bearings are respectively installed on the vertical plates. A rotating shaft is provided between the ball bearings on both sides, and the rotating shaft is divided into upper and lower sets. On the rotating shaft, two sets of retainers limit the movement of rollers. A sponge layer is sleeved on the roller, and the two sets of sponge layers fixed to the rotating shaft via the roller are tangent. On the axle ring of one set of ball bearings on one side, a sleeve is fixed to the outward side of the vertical plate of the fixed support, and the sleeve coincides with the central axis of the rotating shaft. The sleeve is rotatably connected to a C-shaped side bracket via ball bearings, forming a fulcrum. The two ends of the side bracket are welded to a fixed bracket. A driven pulley is mounted on the sleeve, around which a transmission belt is wrapped. The transmission belt also wraps around a driving pulley, which is fixed to the output end of the drive motor. The circulation mechanism includes a liquid storage tank containing coating liquid. One side of the liquid storage tank is connected to two sets of pumps, and each pump is connected to a delivery pipe. The end of the delivery pipe is connected to a spray pipe, which is closed at the end. There are two sets of spray pipes, and both ends of the two sets of spray pipes are inserted and fixed to the vertical plates on both sides of the fixed bracket.

[0007] Furthermore, on the bearing ring, a U-shaped mounting arc plate is fixed to the inward side of the vertical plate of the fixed bracket, and the mounting arc plates on both sides are fixed to the two ends of the rotating shaft by bolts.

[0008] Furthermore, each of the two sets of rotating shafts is equipped with a set of spur gears of the same specification, and the two sets of spur gears mesh with each other.

[0009] Furthermore, one set of the spray pipes is located above the upper rotating shaft, and the bottom of the spray pipe is provided with drip holes at equal intervals, with the drip holes facing the upper sponge layer; the other set of spray pipes is located on one side of the lower rotating shaft, and the side of the spray pipe is provided with pressurized nozzles at equal intervals, with the pressurized nozzles facing the lower sponge layer.

[0010] Furthermore, each of the infusion tubes is equipped with a flow control valve.

[0011] Furthermore, a recycling tank is provided below the sponge layer. The recycling tank is fixed to a fixed bracket, and one end of the recycling tank protrudes from the fixed bracket. The protruding end is connected to a guide pipe, and the lower end of the guide pipe extends into the liquid storage tank.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model features a sponge layer fitted onto a roller. When the coating liquid contacts the sponge layer, its unique structure promotes uniform diffusion of the coating liquid within the sponge, enabling synchronous coating operations on both sides of the transfer film. At both ends of the rotating shaft, mounting arc plates are specially designed. In actual operation, simply unscrewing the bolts on the mounting arc plates with a wrench releases the fastening effect on both ends of the rotating shaft, allowing for easy removal of the sponge layer along with the rotating shaft from the coating structure. This design greatly facilitates the cleaning and replacement of the sponge layer, ensuring that the sponge layer maintains its efficient absorption capacity of the coating liquid, thus effectively guaranteeing excellent coating results.

[0014] 2. This utility model constructs a complete coating liquid recovery system by setting up a recovery tank and a guide pipe. During the coating process, the coating that fails to be successfully adsorbed onto the transfer membrane on the sponge layer and drips off will be collected through the recovery tank and returned to the storage tank through the guide pipe. This design realizes the recycling of coating liquid, effectively reduces material waste, and effectively reduces production costs. Attached Figure Description

Detailed Implementation

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 5 As shown:

[0025] This utility model provides a double-sided transfer coating structure, which includes a driving mechanism and a circulation mechanism. The driving mechanism includes a fixed bracket 1, which is composed of a horizontal plate and two vertical plates on both sides. Two sets of ball bearings 2 are installed on the vertical plates respectively. A rotating shaft 4 is provided between the ball bearings 2 on both sides, and the rotating shaft 4 is divided into upper and lower sets. On the rotating shaft 4, two sets of retaining seats 5 limit the movement of rollers 6. A sponge layer 7 is sleeved on the rollers 6, and the two sets of sponge layers 7 fixed on the rotating shaft 4 via the rollers 6 are tangent. On the axle ring of one set of ball bearings 2 on one side, a sleeve 9 is fixed to the outward side of the vertical plate of the fixed bracket 1. The sleeve 9 coincides with the central axis of the rotating shaft 4. The sleeve 9 is connected to the C-shaped bearing through the ball bearing 2. The side support 10 is rotatably connected to form a fulcrum for the sleeve 9. The two ends of the side support 10 are welded to the fixed support 1. A driven pulley 11 is installed on the sleeve 9. A transmission belt 12 is wrapped around the driven pulley 11. The transmission belt 12 is also wrapped around the driving pulley 13, and the driving pulley 13 is fixed to the output end of the drive motor 14. The circulation mechanism includes a liquid storage tank 19, which contains coating liquid. Two sets of pumps 20 are connected to one side of the liquid storage tank 19. A delivery pipe 21 is connected to the pump 20. The end of the delivery pipe 21 is connected to a spray pipe 15, which is closed at the end. There are two sets of spray pipes 15. The two ends of the two sets of spray pipes 15 are inserted and fixed to the vertical plates on both sides of the fixed support 1.

[0026] Among them, such as Figure 5 As shown, a U-shaped mounting arc plate 3 is fixed to the inner side of the vertical plate of the fixed bracket 1 on the ring of the ball bearing 2. The mounting arc plates 3 on both sides are fixed to the two ends of the rotating shaft 4 by bolts. By unscrewing the bolts from the mounting arc plate 2, the fixing of the mounting arc plate 3 to the two ends of the rotating shaft 4 can be released, thereby removing the sponge layer 7 from the coating structure along with the rotating shaft 4. This facilitates the cleaning or replacement of the sponge layer 7, maintains the good absorption of the coating liquid by the sponge layer 7, and thus ensures the coating effect of the sponge layer 7.

[0027] Among them, such as Figure 2 As shown, on each of the two sets of rotating shafts 4, there is a set of spur gears 8 of the same specification, and the two sets of spur gears 8 mesh with each other; when the drive motor 14 is started, the driving pulley 13, the transmission belt 12 and the driven pulley 11 are driven to run, the sleeve 9 rotates, driving the ball bearing 2 and the upper rotating shaft 4 to rotate, and the lower rotating shaft 4 is driven to rotate synchronously in opposite directions through the two sets of spur gears 8.

[0028] Among them, such as Figure 1As shown, one set of spray pipes 15 is located above the upper rotating shaft 4. The bottom of the spray pipe 15 is provided with drip holes at equal intervals, and the drip holes are directly facing the upper sponge layer 7. The other set of spray pipes 15 is located on one side of the lower rotating shaft 4. The side of the spray pipe 15 is provided with pressurized nozzles 16 at equal intervals, and the pressurized nozzles 16 are directly facing the lower sponge layer 7. The coating liquid is evenly sprayed onto the sponge layer 7 through the spray pipes 15. The sponge layer 7 is designed to absorb the coating on the surface, thereby effectively coloring the transfer film. The sponge layer 7 can evenly spread the coating liquid inside itself, which facilitates the even coloring of the transfer film.

[0029] Among them, such as Figure 3 As shown, each infusion tube 21 is equipped with a flow control valve 22. By adjusting the flow control valve 22, the flow rate of the coating liquid in the infusion tube 21 can be changed, and the spray volume of the spray tube 15 can be adjusted, thereby facilitating the adjustment of the coating effect on the transfer film.

[0030] Among them, such as Figure 1 As shown, a recycling tank 17 is provided below the sponge layer 7. The recycling tank 17 is fixed to the fixed bracket 1, and one end of the recycling tank 17 protrudes from the fixed bracket 1. The protruding end is connected to a guide pipe 18, and the lower end of the guide pipe 18 extends into the liquid storage tank 19. The coating that has not been adsorbed onto the transfer membrane and dripped from the sponge layer 7 is recycled into the liquid storage tank 19 through the recycling tank 17 and the guide pipe 18, so as to realize the recycling of the coating liquid and reduce material consumption.

[0031] The specific usage and function of this embodiment are as follows:

[0032] In this invention, one end of the transfer film to be coated is clamped into the tangential plane of the upper and lower sponge layers 7; the drive mechanism is started, the drive motor 14 is turned on, driving the drive pulley 13, transmission belt 12 and driven pulley 11 to run, the sleeve 9 rotates, driving the ball bearing 2 and the upper rotating shaft 4 to rotate, and the lower rotating shaft 4 is driven to rotate synchronously in opposite directions through two sets of spur gears 8, and the transfer film is clamped by the upper and lower sets of sponge layers 7; at the same time, the circulation mechanism is started, the pump 20 is turned on, and the infusion tube 21 delivers the transfer film to the upper and lower sets of sponge layers 7. The coating liquid contained in the storage tank 19 is transported to the spray pipe 15, which sprays the coating evenly onto the sponge layer 7. The sponge layer 7 can evenly spread the coating liquid inside itself, so as to evenly color the transfer film. The coating effect on the transfer film can be adjusted by adjusting the flow control valve 22. The coating liquid that does not adhere to the transfer film and drips off the sponge layer 7 is recovered into the storage tank 19 through the recovery tank 17 and the guide pipe 18, so as to realize the recycling of the coating liquid and reduce material consumption.
