Description

Technical Field

[0001] This utility model relates to the field of tape production technology, specifically to a coating machine with adjustable coating thickness for tape production. Background Technology

[0002] Coating machines are mainly used for surface coating processes on films, paper, and other materials. The machine coats the substrate with a layer of adhesive, paint, or ink with specific functions, and then rewinds it after drying. Coating machines can produce various forms of surface coating. Both the winding and unwinding mechanisms of the coating machine are equipped with controllers, allowing the controller to regulate the movement speed of the substrate. During the coating process, the required coating thickness varies depending on the material being coated or the plastic film being coated; therefore, the coating thickness needs to be adjusted according to production requirements.

[0003] In adhesive coating operations, adhesive is typically added to the adhesive hopper, and the rotation of the adhesive roller causes the adhesive to adhere to the surface. After contacting the base tape, the adhesive is coated onto the base tape surface. However, during long-term use, because the adhesive in the adhesive hopper is not continuously used, old adhesive often adheres to the inner wall of the adhesive hopper, forming stubborn adhesive. Over time, this will affect the subsequent use of equipment. Therefore, to address the above problems, a coating machine with adjustable coating thickness for tape production is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a coating machine with adjustable coating thickness for tape production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating machine with adjustable coating thickness for tape production, comprising a coating machine, an unwinding roller, and a base tape;

[0006] The top of the coating machine is equipped with an unwinding roller, and a base belt is provided on the outside of the unwinding roller;

[0007] A lower glue frame that is fixedly connected to the coating machine is also provided on one side of the unwinding roller;

[0008] The bottom of the lower glue frame is fixedly connected to a glue spreading mechanism. Below the glue spreading mechanism is a glue storage hopper that is fixedly connected to the coating machine, and on one side of the glue storage hopper is a glue roller that is rotatably connected to the coating machine.

[0009] The adhesive spreading mechanism includes a fixed frame, a motor, and a reciprocating lead screw. The top of the fixed frame is fixedly connected to the lower adhesive frame. The motor is fixedly connected inside the fixed frame. The reciprocating lead screw is fixedly connected to the end of the motor's main shaft. The other end of the reciprocating lead screw is rotatably connected to the fixed frame.

[0010] Furthermore, a slider is slidably connected to the outer side of the reciprocating lead screw, a movable sleeve is fixedly connected to the outer side of the slider, a sliding plate is fixedly connected to the bottom of the movable sleeve, a scraper is fixedly connected to the bottom of the sliding plate, a rejection ring is fixedly connected to the bottom of the scraper, and a heating cylinder is slidably connected to the inside of the rejection ring.

[0011] The outer side of the scraper is in close contact with the glue storage hopper.

[0012] Furthermore, the scraper has inclined surfaces on both sides, and the removal ring is arranged in a ring shape.

[0013] During the adhesive application process, adhesive is typically added to the glue hopper. A rotating roller then applies the adhesive to the surface of the substrate, coating it with the adhesive. However, over time, because the adhesive in the hopper is not continuously used, old adhesive often adheres to the inner wall, forming stubborn adhesive. This can affect subsequent equipment use. To resolve this, the power is switched on, and the adhesive enters the hopper through the lower glue frame. The motor then drives a reciprocating screw, which in turn moves a slider. The slider moves an outer moving sleeve, which in turn moves a sliding plate and scraper. The scraper continuously scrapes the inner wall of the hopper, removing stubborn adhesive and preventing it from hardening and becoming unusable.

[0014] Furthermore, the heating cylinder is fixedly connected to the glue storage hopper on both sides, a heating rod is fixedly connected inside the heating cylinder, and the inside of the heating cylinder is filled with water.

[0015] Furthermore, one side of the glue storage hopper is in close contact with the glue roller, and the side of the glue storage hopper away from the glue roller is inclined.

[0016] Furthermore, the heating cylinder is made of copper tubing.

[0017] Before being added, adhesives are heated by a heating mechanism to maintain their fluidity. However, once added to the adhesive storage hopper, if not used in time, the temperature of the adhesive drops, which will reduce its fluidity and affect subsequent feeding. This device uses a heating cylinder and heating rod to heat the water and the external adhesive, ensuring its fluidity and facilitating its use.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] When this utility model is in use, when the adhesive enters the glue storage hopper through the lower glue frame, the motor is started to drive the reciprocating screw to rotate. The reciprocating screw drives the slider to move, and the slider drives the outer moving sleeve to move. The moving sleeve drives the sliding plate and scraper to move back and forth. At this time, the scraper can continuously scrape the inner wall of the glue storage hopper, so that the stubborn adhesive adhering to the inner wall of the glue storage hopper can be scraped and used, preventing it from solidifying and becoming unusable. At the same time, the scraper also serves to spread the adhesive evenly, ensuring that the adhesive falls stably and evenly.

[0020] Before being added, adhesives are heated by a heating mechanism to maintain their fluidity. However, once added to the adhesive storage hopper, if not used in time, the temperature of the adhesive drops, which will reduce its fluidity and affect subsequent feeding. This device uses a heating cylinder and heating rod to heat the water and the external adhesive, ensuring its fluidity and facilitating its use. Attached Figure Description

[0026] 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.

[0027] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution:

[0028] An adjustable coating machine for tape production includes a coating machine 1, an unwinding roller 2, and a base tape 3;

[0029] The top of the coating machine 1 is equipped with an unwinding roller 2, and a base belt 3 is provided on the outer side of the unwinding roller 2;

[0030] The unwinding roller 2 is also provided with a lower glue frame 5 that is fixedly connected to the coating machine 1 on one side;

[0031] The bottom of the lower glue frame 5 is fixedly connected to the glue spreading mechanism 6. Below the glue spreading mechanism 6, there is a glue storage hopper 7 that is fixedly connected to the coating machine 1, and on one side of the glue storage hopper 7, there is a glue roller 4 that is rotatably connected to the coating machine 1.

[0032] The adhesive spreading mechanism 6 includes a fixed frame 601, a motor 602 and a reciprocating lead screw 603. The top of the fixed frame 601 is fixedly connected to the lower adhesive frame 5. The motor 602 is fixedly connected inside the fixed frame 601. The reciprocating lead screw 603 is fixedly connected to the end of the main shaft of the motor 602. The other end of the reciprocating lead screw 603 is rotatably connected to the fixed frame 601.

[0033] A slider 604 is slidably connected to the outer side of the reciprocating screw 603. A movable sleeve 605 is fixedly connected to the outer side of the slider 604. A sliding plate 606 is fixedly connected to the bottom of the movable sleeve 605. A scraper 607 is fixedly connected to the bottom of the sliding plate 606. A removal ring 608 is fixedly connected to the bottom of the scraper 607. A heating cylinder 8 is slidably connected inside the removal ring 608.

[0034] The outer side of the scraper 607 is in close contact with the glue storage hopper 7.

[0035] The scraper 607 has inclined surfaces on both sides, and the removal ring 608 is arranged in a ring shape.

[0036] During the adhesive application process, adhesive is typically added to the adhesive hopper. A rotating roller then applies the adhesive to the surface of the substrate, coating it with the adhesive. However, over time, because the adhesive in the hopper is not continuously used, old adhesive often accumulates on the inner wall, forming stubborn residue. This can affect subsequent equipment operation. When in use, the power is turned on, and the adhesive enters the storage hopper 7 through the lower adhesive frame 5, triggering the process. Motor 602 drives reciprocating screw 603 to rotate, reciprocating screw 603 drives slider 604 to move, slider 604 drives outer moving sleeve 605 to move, moving sleeve 605 drives sliding plate 606 and scraper 607 to move back and forth. At this time, scraper 607 can continuously scrape the inner wall of glue storage hopper 7, so that the stubborn glue adhering to the inner wall of glue storage hopper 7 can be scraped and used, avoiding it from solidifying and becoming unusable. At the same time, scraper 607 can also flatten the glue, ensuring that the adhesive falls stably and evenly.

[0037] In this embodiment, the scraper 607 is inclined on both sides. When scraping the adhesive, the adhesive adheres to the surface of the scraper 607. Due to the inclined surface of the scraper 607, the adhesive can easily fall and be used. The removal ring 608 is set to scrape the adhesive on the outside of the heating cylinder 8, which facilitates the use of the adhesive. The glue storage hopper 7 is inclined and contacts the glue roller 4 on both sides. At this time, the adhesive can fall through the gap between the glue storage hopper 7 and the glue roller 4, ensuring the continuous use of the adhesive. The lower glue frame 5 is connected to the glue tube for conveying the glue, which facilitates the glue to fall into the glue storage hopper 7 through the discharge nozzle inside the lower glue frame 5 for use.

[0038] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 1 Specifically, the two sides of the heating cylinder 8 are fixedly connected to the glue storage hopper 7, the heating rod 9 is fixedly connected inside the heating cylinder 8, and the inside of the heating cylinder 8 is filled with water.

[0039] One side of the aforementioned glue storage hopper 7 is in close contact with the glue roller 4, and the side of the aforementioned glue storage hopper 7 away from the glue roller 4 is inclined.

[0040] The heating cylinder 8 mentioned above is made of copper tubing.

[0041] Before being added, the adhesive is heated by a heating mechanism to maintain its fluidity. However, once it is added into the adhesive storage hopper 7, if it is not used in time, the temperature of the adhesive will drop, and its fluidity will deteriorate, which will affect the subsequent feeding work. This device uses a heating cylinder 8 and a heating rod 9 to heat the water and heat the external adhesive through the heating cylinder 8 to ensure its fluidity and facilitate its use.

[0042] In this embodiment, the heating cylinder 8 is made of copper, which has a good purpose of heat exchange, and the water heating method is stable and can effectively ensure the fluidity of the adhesive.
