Description

Technical Field

[0001] The utility model relates to the field of tape production, in particular to a tape coating assembly. Background Art

[0002] In the traditional tape coating process, the glue solution is often placed below the coating roller, and the glue solution is brought to the tape surface by the rotation of the coating roller. However, as the coating process progresses, the glue solution in the glue tank will gradually decrease, and the area of the glue solution adhered to the coating roller will also shrink accordingly, resulting in uneven distribution of the glue solution on the tape surface.

[0003] The uneven distribution of the glue solution will directly affect the coating quality of the tape, making the glue layer too thick in some areas of the tape, while in other areas it may be too thin or even there may be missed coating. This will not only affect the use performance of the tape, but also may reduce its yield rate and market acceptance.

[0004] Since the glue solution will gradually decrease during the coating process, the operator needs to continuously replenish the glue solution into the glue tank to keep the glue solution on the coating roller sufficient. Frequent replenishment of the glue solution not only increases the labor intensity of the operator, but also may cause fluctuations in the coating quality due to untimely replenishment or inaccurate replenishment amount. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a tape coating assembly, and solve the following technical problems: how to ensure the uniform distribution of the glue solution on the surface of the coating roller, and how to improve the stability and efficiency of the coating process.

[0006] To solve the problems existing in the prior art, the technical solution adopted by the utility model is as follows:

[0007] A tape coating assembly includes a coating box. Inside the coating box, coating rollers are symmetrically and rotatably connected. The coating rollers are in mutual contact. Below the coating rollers inside the coating box, pressure rollers are symmetrically and rotatably connected. On both sides of the coating box, discharge ports are provided between the coating rollers and the pressure rollers, and on both sides of the coating box, feed ports are provided at the bottom of the pressure rollers.

[0008] Preferably, an adhesive layer is provided on the outer side of the coating roller, and the adhesive layers on the outer sides of the coating rollers are in mutual extrusion contact. When the coating rollers rotate, the adhesive layers are mutually extruded, which helps the glue to form a uniform coating.

[0009] Preferably, the bottom of the coating box is arranged in a sunken and converging manner. The sunken and converging bottom design can gather the excess glue that has not been fully utilized and dripped together, facilitating subsequent treatment and discharge.

[0010] Preferably, a drain pipe is fixedly connected to one side of the bottom of the coating box, and the excess glue collected at the bottom of the coating box can be conveniently discharged to the outside through the drain pipe.

[0011] Preferably, a soft plug is slidably inserted at the outer end of the drain pipe. The function of the soft plug is to control the on-off state of the drain pipe.

[0012] Preferably, a closed frame is fixedly connected inside the coating box on the outer side of the coating roller. The coating roller is in contact with the closed frame. The closed frame can prevent the glue from overflowing from both sides of the coating roller and directly entering the lower chamber.

[0013] Preferably, retaining plates are symmetrically and fixedly connected to the outer side of the pressure roller. The retaining plates are used to guide and stabilize the path of the tape during the coating process.

[0014] Compared with the related art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, the glue solution is arranged above the coating roller and is designed to be able to submerge the upper surface of the coating roller, ensuring that the coating roller can continuously and evenly adhere to the glue solution during rotation. This method avoids the problem that the glue - sticking area of the coating roller gradually shrinks due to the reduction of the glue solution in the traditional design, thus ensuring the consistency and uniformity of tape coating.

[0016] 2. Since the glue solution can always submerge the upper surface of the coating roller, the coating roller can continuously and stably carry enough glue solution for coating during rotation without frequent replenishment of the glue solution. This not only reduces the labor intensity of the operator but also significantly improves the efficiency of the coating operation.

[0017] 3. By the method of quantitatively pouring the glue, the usage amount of the glue solution can be accurately controlled, effectively reducing the waste of the glue.

[0018] 4. When the coating rollers contact each other during rotation, the adhesive layers on their outer sides will squeeze and rub against each other. This interaction not only helps to evenly distribute the glue solution on the entire surface of the coating roller but also further refines the distribution of the glue solution through friction, making it more uniform and delicate.

[0023] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] The tape coating assembly has a coating box 1;

[0025] As Figures 1 to 3 shown, inside the coating box 1, coating rollers 2 are symmetrically and rotatably connected. The coating rollers 2 are in mutual contact. Inside the coating box 1, below the coating rollers 2, pressure rollers 3 are symmetrically and rotatably connected. On both sides of the coating box 1, between the coating rollers 2 and the pressure rollers 3, there are discharge ports 4. At the bottom of the pressure rollers 3 on both sides of the coating box 1, there are feed ports 5;

[0026] Inside the coating box 1, through the ingenious design of the coating rollers 2 and the enclosing frame 9, two relatively independent chambers are formed, the upper chamber is mainly used for storing and preliminarily distributing the glue, and the lower chamber is the area where the tape interacts with the coating rollers 2 and the pressure rollers 3;

[0027] The glue is injected into the upper chamber of the coating box 1, and the glue is preliminarily dispersed and prepared in this area. Subsequently, under the rotation of the coating rollers 2, it is evenly adhered to the outside of the coating rollers 2. Since the coating rollers 2 are arranged in pairs and in mutual contact, their rotational movement ensures that a uniform coating is formed on the adhesive layer 6;

[0028] The tape to be coated enters the lower chamber of the coating box 1 from the feed port 5. The tape, under the guidance of the pressure rollers 3, bypasses the pressure rollers 3 and tightly passes through the narrow gap between the pressure rollers 3 and the coating rollers 2. During the mutual rotation of the coating rollers 2 and the pressure rollers 3, the surface of the tape comes into contact with the adhesive layer 6 on the outside of the coating rollers 2. The glue on the coating rollers 2 is evenly transferred to the surface of the tape under the action of rotational friction force, realizing the coating of the glue. After the coating is completed, the tape continues to move forward and is discharged from the coating box 1 through the discharge port 4. At this time, the surface of the tape has been evenly covered with a layer of glue, achieving the expected coating effect.

[0029] As Figures 1 to 3 shown, an adhesive layer 6 is provided on the outside of the coating rollers 2. The adhesive layers 6 on the outside of the coating rollers 2 are in mutual extrusion contact. This adhesive layer 6 is the key medium for transferring the glue from the upper chamber of the coating box 1 to the tape. When the two coating rollers 2 are in mutual contact and rotate, the adhesive layers 6 on their outsides will be mutually extruded. This extrusion not only helps to form a uniform coating of the glue on the adhesive layer 6, but also can evenly transfer the glue to the surface of the passing tape through the frictional force;

[0030] As Figures 1 to 3As shown, the bottom of the coating box 1 is set in a sunken and converging manner. After the glue is evenly coated on the surface of the tape by the coating roller 2, some of the glue may drip onto the bottom of the coating box 1 without being fully utilized. The sunken and converging bottom design can concentrate these excess glues together, facilitating subsequent treatment and discharge, thereby maintaining the cleanliness inside the coating box 1 and the smooth progress of the coating process.

[0031] As Figures 1 to 3 shown, a drain pipe 7 is fixedly connected to one side of the bottom of the coating box 1. The drain pipe 7 is an important channel for treating excess glue. Through the drain pipe 7, the excess glue collected at the bottom of the coating box 1 can be safely and effectively discharged to an external treatment system.

[0032] As Figures 1 to 3 shown, a soft plug 8 is slidably inserted into the outer end of the drain pipe 7. The function of the soft plug 8 is to control the on-off state of the drain pipe 7. When it is necessary to discharge the excess glue, the soft plug 8 can be pulled out to open the drain pipe 7.

[0033] As Figures 1 to 3 shown, a closed frame 9 is fixedly connected to the inside of the coating box 1 outside the coating roller 2. The coating roller 2 is in contact with the closed frame 9. The closed frame 9 is provided to prevent the glue from overflowing from both sides of the coating roller 2 and directly entering the lower chamber.

[0034] As Figures 1 to 3 shown, baffles 10 are symmetrically and fixedly connected to the outside of the pressure roller 3. The baffles 10 are used to guide and stabilize the path of the tape during the coating process.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
