Description

Technical Field

[0001] This utility model relates to the technical field of tape production, specifically a coating device for tape production. Background Technology

[0002] Tape coating is a device that applies a layer of coating or oil with specific functions to the surface of tape during the production process. By coating the tape surface with a specific function, it achieves a special protective effect. Existing coating devices on the market typically use a rotating roller to apply the coating liquid. The rotating roller absorbs the coating liquid, and the tape to be coated moves outside the roller, thus achieving the coating effect. However, in existing devices, the rotating roller is in direct contact with a large amount of coating liquid, resulting in uneven application and uneven coating. While typical coating devices have scraping mechanisms to remove excess coating from the rotating roller, the coating liquid scraped off by these mechanisms is often not fully reused, leading to significant waste of coating liquid. Utility Model Content

[0003] The purpose of this invention is to provide a coating device for tape production, which solves the problem mentioned in the background art of current coating devices on the market. In these devices, the rotating roller directly contacts a large amount of coating liquid during adsorption, resulting in uneven adsorption of the coating liquid on the rotating roller. Consequently, uneven coating occurs during the coating process. In general coating devices, a scraping mechanism is provided to scrape off excess coating liquid from the rotating roller. However, the coating liquid scraped off by the scraping mechanism is often not fully reused, leading to serious waste of coating liquid.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a coating device for tape production, comprising a device body, which is arranged in a hollow rectangular structure and has an open top;

[0005] The conveyor wheels are located at the top of both sides of the main body of the device and are used for conveying the conveyor belt.

[0006] Also includes;

[0007] Two inclined baffles are symmetrically arranged inside the main body of the device;

[0008] The coating mechanism includes a liquid-impregnated cotton, an extrusion mechanism, and a coating wheel;

[0009] The impregnated cotton is fitted inside the main body of the device, and a squeezing mechanism is provided at its top. A coating wheel is provided at the middle of the top of the squeezing mechanism. The coating wheel rotates to squeeze the squeezing mechanism so that it comes into contact with the coating liquid squeezed out from inside the impregnated cotton, thereby achieving the coating effect.

[0010] Preferably, two sets of inclined baffles are symmetrically arranged at the top positions on both sides of the main body of the device, and the top of each baffle is in contact with the outer wall of the coating wheel, and the outer wall of the inclined baffle is in contact with the inner wall of the main body of the device.

[0011] The coating wheel is provided with a cam on its outside, and the cam can squeeze the extrusion mechanism when it rotates.

[0012] Preferably, the inside of the soaked cotton is fully soaked in the coating liquid, and the squeezing mechanism at its top can move up and down above it to achieve the effect of squeezing out the liquid by moving up and down.

[0013] Preferably, the extrusion mechanism includes;

[0014] The squeeze baffle has its top end in contact with the bottom end of the inclined baffle, and a through-hole is provided in the center of the squeeze baffle for liquid discharge.

[0015] The position of the extrusion port corresponds to the position of the coating wheel, and the size of the extrusion port is larger than the size of the coating wheel.

[0016] Preferably, the compression baffle moves up and down under the action of a sliding mechanism, the sliding mechanism comprising:

[0017] A slider is provided outside the extrusion baffle, and its bottom is connected to the bottom of a reserved slide groove by a compression spring. The reserved slide groove is embedded in the inner wall of the main body of the device.

[0018] The top of the reserved groove is on the same plane as the top of the coating wheel.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This coating device for tape production absorbs the coating liquid, which is traditionally stored directly, into the interior of the impregnated cotton. Then, through the continuous up-and-down movement of the extrusion mechanism on the entire device, the coating liquid absorbed inside the impregnated cotton is squeezed out at the extrusion port. Thus, the coating wheel can be rotated and absorbed, ensuring that the coating liquid can be evenly absorbed on the coating wheel. This prevents the phenomenon of too much or too little coating liquid being absorbed. At the same time, excess coating liquid can return to the interior of the impregnated cotton, thus ensuring that the coating liquid is fully utilized and there is no waste.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This utility model provides a technical solution: a coating device for tape production, including a device body 1, which is a hollow rectangular structure with an open top.

[0029] The conveyor wheel 2 is located at the top of both sides of the main body 1 of the device and is used for conveying the tape.

[0030] Also includes;

[0031] Two inclined baffles 4 are symmetrically arranged inside the main body 1 of the device.

[0032] The coating mechanism includes a liquid-impregnated cotton 5, an extrusion mechanism 6, and a coating wheel 3;

[0033] The impregnated cotton 5 is fitted inside the main body 1 of the device, and a squeezing mechanism 6 is provided at its top. A coating wheel 3 is provided at the middle position of the top of the squeezing mechanism 6. The coating wheel 3 rotates to squeeze the squeezing mechanism 6 to make contact with the coating liquid squeezed out from inside the impregnated cotton 5, thereby achieving the coating effect.

[0034] Two sets of inclined baffles 4 are symmetrically arranged at the top of both sides of the main body 1 of the device, and their tops are in contact with the outer wall of the coating wheel 3, and the outer wall of the inclined baffles 4 is in contact with the inner wall of the main body 1 of the device.

[0035] The coating wheel 3 is provided with a cam 31 on its outside, and the cam 31 can squeeze the extrusion mechanism 6 when it rotates;

[0036] Specifically, the inclined baffle 4 can protect the top of the entire device body 1. Since the inclined baffle 4 is in contact with the coating wheel 3, when the tape at the bottom of the coating wheel 3 is coated and transported, the inclined baffle 4 can also scrape the surface of the tape to achieve a uniform coating effect.

[0037] The inside of the liquid-impregnated cotton 5 is fully soaked in the coating liquid, and the squeezing mechanism 6 at its top can move up and down above it to achieve the effect of squeezing out the liquid by moving up and down.

[0038] Specifically, the cam 31 is designed so that when it rotates with the coating wheel 3, the top of the cam 31 can squeeze the extrusion mechanism 6, thereby enabling the extrusion mechanism 6 to squeeze the impregnated cotton 5 to release liquid.

[0039] The extrusion mechanism 6 includes;

[0040] The top of the extrusion baffle 61 contacts the bottom of the inclined baffle 4, and a through extrusion port 62 is provided in the center of the extrusion baffle 61 for liquid discharge.

[0041] The position of the extrusion port 62 corresponds to the position of the coating wheel 3, and the size of the extrusion port 62 is larger than the size of the coating wheel 3.

[0042] The compression baffle 61 moves up and down under the action of the sliding mechanism, which includes:

[0043] The slider 63 is set outside the extrusion baffle 61, and its bottom is connected to the bottom of the reserved slide groove 65 by a compression spring 64. The reserved slide groove 65 is embedded in the inner wall of the device body 1.

[0044] The top of the reserved groove 65 is on the same plane as the top of the coating wheel 3;

[0045] Specifically, when the extrusion baffle 61 descends, it will squeeze the impregnated cotton 5, so that the coating liquid inside it can be discharged at the extrusion port 62, thus achieving the effect of being coated by the coating wheel 3.

[0046] Working Principle: When using this tape coating device, the entire device body 1 is placed in a suitable position. Then, one side of the tape first passes through the conveyor wheel 2 on one side of the device body 1, then through the bottom of the coating wheel 3, and then through the conveyor wheel 2 again, thus enabling tape conveying. Afterwards, the coating process can begin. During coating, the external motor of the coating wheel 3 needs to be started, causing the motor to drive the coating wheel 3 to rotate. As the coating wheel 3 rotates, it also drives the cam 31, which is coaxially connected to it, to rotate. When the cam 31 rotates, it presses against the extrusion baffle 61 above it, causing the extrusion baffle 61 to press against the slider 63. The tape slides inside the reserved groove 65. When the extrusion baffle 61 descends, it extrudes the impregnated cotton 5, causing the coating liquid on the impregnated cotton 5 to be squeezed out at the extrusion port 62. Then, it comes into contact with the rotating coating wheel 3, achieving a uniform coating effect. Thus, when the tape passes over the surface of the coating wheel 3, the coating work is completed. During the coating process, due to the inclined baffle 4, the surface of the tape coated by the coating wheel 3 can still be smoothed by the inclined baffle 4, achieving a uniform coating effect. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0047] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
