Description

Technical Field

[0001] This utility model relates to the field of tape processing technology, specifically to a tape coating machine that provides uniform coating. Background Technology

[0002] Coating machines are mainly used for surface coating processes on films, paper, etc. This machine coats a roll of substrate with a layer of adhesive, paint, or ink with specific functions, and then dries it before cutting it into sheets or rewinding it. Tape coating machines have two coating methods: one is to coat a photosensitive emulsion onto a screen through multiple wet-on-wet operations, and the other is to add a drying process after each coating step, quantitatively coating the material surface with liquid polymer materials such as adhesives or paints.

[0003] Existing technologies, such as the utility model patent with publication number CN222587076U, describe an aluminum foil tape coating machine, which includes a motor and a housing. The output shaft of the motor is fixedly connected to a threaded rod, and a threaded block is threadedly connected to the outer surface of the threaded rod. A support block is fixedly connected to the upper surface of the threaded block, and a cleaning component is fixedly connected to the upper surface of the support block. Both ends of a guide rod are fixedly connected to the inner wall of the housing. The motor drives the threaded rod to rotate, and the threaded connection between the threaded rod and the threaded block enables the threaded block to move. The guide rod limits the movement of the threaded block, which in turn moves the support block. The support block then causes the cleaning component to contact the surface of the transmission roller, thus cleaning the transmission roller. This allows the device to easily clean the transmission roller and prevents excess adhesive residue from remaining on the surface of the transmission roller during the coating process, which would affect the efficiency of aluminum foil tape coating.

[0004] In this technical solution, the cleaning component affects the winding process of the substrate during the cleaning of the transmission roller, which can easily cause the aluminum foil to shift position, resulting in wrinkles and affecting product quality.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a tape coating machine that can effectively solve the above-mentioned technical problems and achieve uniform coating.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: a tape coating machine for uniform coating, comprising: a base, a tape, and a coating mechanism for uniformly coating the tape with adhesive.

[0008] The adhesive application mechanism includes: a first motor, the output shaft of the first motor being fixedly connected to a rotating shaft, a take-up roller being fixedly mounted on the rotating shaft, one end of an adhesive tape being fixedly connected to the take-up roller, the other end of the adhesive tape being fixedly connected to a driven roller, and the adhesive tape passing through the side of a limiting roller and a rotating roller.

[0009] Furthermore, the limiting roller and the driven roller are fixedly mounted on the roller shaft.

[0010] Furthermore, the rotating roller is rotatably and fixedly mounted on a fixed rod, which is fixedly mounted on a fixed frame, and the bottom ends of the fixed frame are provided with grooves.

[0011] Furthermore, the limiting rollers are symmetrically distributed on both sides of the fixed frame, and the distance between the limiting rollers and the fixed frame is equal to the thickness of the tape.

[0012] Furthermore, the bottom of the fixing frame is provided with a semi-circular groove, and the side of the rotating roller slides in contact with the inner wall of the semi-circular groove.

[0013] Furthermore, a hot melt pool is installed below the rotating roller, and a stirring shaft rotates and passes through the bottom of the hot melt pool. The stirring shaft is fixedly connected to the output shaft of the second motor, and a stirring paddle is installed circumferentially on the stirring shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a tape coating machine for uniform coating. During the tape winding process, the tape comes into contact with the adhesive in the hot melt pool, so that the adhesive adheres to the tape. Furthermore, the back of the tape is in close contact with the rotating roller and the surface of the fixed frame, preventing the adhesive from sticking to the back of the tape. At the same time, it avoids the rotating roller body from coming into contact with the adhesive, eliminating the need for frequent cleaning of the rotating roller and improving the practicality of the device.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a mechanism is referred to as being "fixed to" another mechanism, it can be directly on the other mechanism or there may be an intervening mechanism. When a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intervening mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it can be directly set on the other mechanism or there may be an intervening mechanism at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0022] like Figures 1 to 3 As shown, this utility model discloses a tape coating machine for uniformly coating adhesive 5, comprising: a base 1, an adhesive tape 5, and a coating mechanism 4 for uniformly coating adhesive onto the tape 5; multiple telescopic rods 2 are fixedly installed on the base 1, and a mounting frame 3 is fixedly connected to the upper end of the telescopic rods 2. The mounting frame 3 can be adjusted in position and height by pushing the mounting frame 3 with an electric telescopic rod 2. The coating mechanism 4 uniformly coats the adhesive onto the tape 5 and prevents the adhesive from solidifying, so that the adhesion of the adhesive will not affect the coating process of the tape 5.

[0023] The adhesive application mechanism 4 includes: a first motor 41, which is fixedly mounted on a mounting frame 3. The output shaft of the first motor 41 is fixedly connected to a rotating shaft 42, which is rotatably mounted on the mounting frame 3. A take-up roller 43 is fixedly mounted on the rotating shaft 42. The output shaft of the first motor 41 drives the rotating shaft 42 to rotate, which in turn drives the take-up roller 43 to rotate. One end of an adhesive tape 5 is fixedly connected to the take-up roller 43, and the other end of the adhesive tape 5 is fixedly connected to a driven roller 44. The adhesive tape 5 is wound up on the driven roller 44. The tape 5 is wound up by the rotation of the take-up roller 43. The tape 5 drives the driven roller 44 to rotate, so that the tape 5 is in the process of being released and wound up. During this process, adhesive is applied to one side of the tape 5. The tape 5 passes the side of the limiting roller 46 and the rotating roller 47. The limiting roller 46 and the driven roller 44 are both fixedly installed on the roller shaft 45, and the roller shaft 45 is rotatably installed on the mounting frame 3. The limiting roller 46 limits the tape 5 and keeps the tape 5 in a taut state, so that the tape 5 is coated with adhesive at the position of the rotating roller 47.

[0024] The rotating roller 47 is rotatably and fixedly mounted on a fixed rod, which is fixedly mounted on a fixed frame 471. The fixed frame 471 is fixedly mounted inside the mounting frame 3. The bottom ends of the fixed frame 471 have grooves 472, and a hot melt pool 412 is installed below the rotating roller 47. The edge of the hot melt pool 412 is aligned with the groove 472. When the mounting frame 3 lowers the fixed frame 471, the edge of the hot melt pool 412 inserts into the groove 472, preventing obstruction of the descent of the fixed frame 471 and allowing the rotating roller 47 to descend smoothly. The tape 5 is moved into the hot melt pool 412, so that one side of the tape 5 comes into contact with the adhesive. The bottom of the hot melt pool 412 rotates and passes through a stirring shaft. A sealing ring is rotatably installed on the stirring shaft, and the sealing ring is fixedly installed at the bottom of the hot melt pool 412. The sealing ring seals the position at the bottom of the hot melt pool 412 where it passes through the stirring shaft, preventing the adhesive from leaking. The stirring shaft is fixedly connected to the output shaft of the second motor 410. A stirring paddle 411 is installed circumferentially on the stirring shaft. By heating and stirring the adhesive, the adhesive is prevented from solidifying and affecting the adhesive application process.

[0025] It should be noted that the limiting rollers 46 are symmetrically distributed on both sides of the fixing frame 471, and the distance between the limiting rollers 46 and the fixing frame 471 is equal to the thickness of the tape 5. The limiting rollers 46 limit the tape 5, so that the back of the tape 5 is tightly attached to the fixing frame 471, preventing the adhesive in the hot melt pool 412 from sticking to the back of the tape 5, which would affect the winding of the tape 5.

[0026] Furthermore, the bottom of the fixing frame 471 is provided with a semi-circular groove, the side of the rotating roller 47 slides in contact with the inner wall of the semi-circular groove, the two ends of the rotating roller 47 are immersed in the adhesive in the hot melt pool 412, and the edge of the semi-circular groove can scrape off the adhesive stuck on the rotating roller 47, and the scraped adhesive falls into the hot melt pool 412, which can be reused and reduce adhesive loss.

[0027] It should be added that a second scraper 49 is installed below the limiting roller 46 near the take-up roller 43, and a first scraper 48 is installed below the tape 5 between the limiting roller 46 and the take-up roller 43. The first scraper 48 and the second scraper 49 are fixedly installed on the inner wall of the mounting frame 3, and there is a gap between the first scraper 48 and the tape 5, so that the first scraper 48 can scrape off the excess adhesive on the tape 5, thereby making the adhesive distribution and thickness on the tape 5 uniform. The second scraper 49 contacts the side of the limiting roller 46, and scrapes off the adhesive on the limiting roller 46 by the second scraper 49, so as to avoid the adhesive being difficult to handle after solidification. The scraped adhesive falls into the hot melt pool 412 and can be reused.

[0028] Working principle:

[0029] By passing the tape 5 through the hot melt pool 412, one side of the tape 5 can be evenly coated with adhesive, avoiding areas where there is no adhesive. The height of the mounting frame 3 is adjusted by the electric telescopic rod 2, so that the position of the rotating roller 47 is lowered synchronously with the liquid level of the adhesive in the hot melt pool 412, ensuring the coating effect. The adhesive on the rotating roller 47 is scraped off by the edge of the semi-circular groove on the fixing frame 471, and the surface of the fixing frame 471 is in close contact with the back of the tape 5 to prevent the adhesive from affecting the winding of the tape 5. The scraped adhesive falls directly into the hot melt pool 412 and can be reused without causing the tape 5 to shift or stop the operation of the device, thus improving the practicality of the device.
