Abstract
Description
Technical Field
[0001] This utility model relates to the field of winding and unwinding devices, and in particular to a winding and unwinding device for coating and gluing. Background Technology
[0002] In existing technologies, non-woven paper tape is an adhesive tape material based on non-woven fabric, made of polyester or polyester fibers. It features moisture resistance, breathability, softness, and thinness, allowing for direct skin contact without irritation. Its core advantage lies in combining breathability, adhesion, and protection, making it widely applicable to various scenarios. The application of non-woven paper tape requires the use of a winding and unwinding device to quickly and cleanly complete the coating and winding process, ensuring a good roll finish.
[0003] A search revealed a Chinese patent application with patent number 202221409488.X, which discloses a gluing device for tape production. By setting up a drying chamber, when the glued tape is conveyed to the transmission roller, the fan and heating wire at the top of the drying chamber can dry the glued tape to a certain extent, which can speed up the drying efficiency of the glue and ensure high-quality and high-efficiency production of tape.
[0004] The aforementioned patent has the following shortcomings: during the winding process, when the adhesive is squeezed, it is easy for it to spread to the surroundings, resulting in adhesive spilling from the end of the tape roll. The adhesive spilling from the end of the tape roll can easily contaminate the entire device, which is not conducive to continuing the winding of the nonwoven fabric after coating. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coating and adhesive application device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A coating and adhesive application device, comprising:
[0008] The glue collection box is used to collect excess glue generated during the glue application process.
[0009] The unwinding shaft is located at one end of the top of the take-up box, and a roll of non-woven fabric is fixedly installed on its outer wall;
[0010] A take-up shaft is located at the other end of the top of the take-up box, and a roll of tape is fixedly installed on its outer wall;
[0011] The pressure roller is positioned below the take-up shaft and has a pressure roller positioning shaft rotatably mounted inside it. Both ends of the pressure roller positioning shaft are fixedly mounted with end mounting arms. A pressure roller scraping arm is fixedly connected to the bottom between the two end mounting arms, and a pressure roller cleaning pad is fixedly connected to the top of the pressure roller scraping arm.
[0012] As a further embodiment of this utility model: lifting sliding arms are fixedly installed at both ends of the pressure roller positioning shaft, and a guide shaft is rotatably installed at the top of the two lifting sliding arms.
[0013] As a further embodiment of this utility model: the lower outer wall of the lifting slide arm is slidably sleeved with a limiting slide cylinder, and the bottom inner wall of the limiting slide cylinder is fixedly installed with a limiting slide column.
[0014] As a further embodiment of this utility model: a limiting spring is sleeved on the outer wall of the limiting slide column, and a sliding insertion hole is provided at the bottom end of the lifting slide arm, and the limiting slide column is slidably installed inside the sliding insertion hole.
[0015] As a further embodiment of this utility model: a mounting arm is rotatably mounted on one end of the unwinding shaft, and a servo motor for driving the unwinding shaft is fixedly mounted on the back of the mounting arm.
[0016] As a further embodiment of this utility model: a second mounting arm is rotatably mounted on one end of the take-up shaft, and a second servo motor for driving the take-up shaft is fixedly mounted on the back of the second mounting arm.
[0017] As a further improvement of this utility model: a glue-spraying box is provided at the top center of the glue collection box, and a mounting cross arm is fixedly installed at the top of the glue-spraying box.
[0018] As a further improvement of this utility model: a glue-spreading scraper is fixedly installed on one side of the mounting cross arm, and support columns are fixedly installed at the bottom of both ends of the mounting cross arm.
[0019] Compared with the prior art, the present invention provides a coating and adhesive application device, which has the following advantages:
[0020] 1. This coating and adhesive application device collects excess adhesive generated during the coating and winding process through a take-up box, reducing adhesive waste and lowering raw material costs. The squeegee and pressure roller work together: after the coating box sprays adhesive, the squeegee smooths the adhesive on the surface of the nonwoven fabric and removes excess adhesive; during winding, the pressure roller squeezes the tape roll to further squeeze out residual adhesive, ensuring a uniform adhesive layer, improving tape quality, and avoiding defective products caused by excessive or uneven adhesive thickness.
[0021] 2. The coating and adhesive application device uses a servo motor to drive the unwinding shaft and a servo motor to drive the rewinding shaft. Both are synchronously controlled by a main controller, ensuring that the unwinding and rewinding speeds are matched and avoiding problems such as uneven fabric tension, deviation, or breakage.
[0022] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0040] Working principle:
[0041] Please refer to Figures 1 to 4 Assemble the device as shown in the figure;
[0042] When using this device, the nonwoven fabric roll 7 is first unwound counterclockwise from below. The unwound nonwoven fabric passes under the two guide shafts 10, then over the guide shaft 27, and is wound up by the tape roll 20 from below the winding shaft 18. During the above process, the glue supply pump 3 supplies glue to the glue application tank 13, which sprays the glue onto the upper surface of the nonwoven fabric, which is then smoothed by the glue leveling scraper 15. During the winding process of the tape roll 20, the pressure roller 22 squeezes the nonwoven fabric during the winding process to squeeze out excess glue. Then, the pressure roller 22 is cleaned by the pressure roller scraper arm 24 and the pressure roller cleaning pad 31.
