Description

Technical Field

[0001] The utility model relates to the technical field of trademark tape production equipment, in particular to a wet coating device for mosquito-proof trademark tape. Background Technique

[0002] The trademark ribbon is a small piece of fabric used as a commodity logo. The trademark ribbon uses high-count cotton yarn, polyester filament, nylon filament or rayon as warp and weft threads, weaves a plain or satin ribbon blank on a ribbon loom, and after dyeing, sizing, scraping and cutting, it is printed by a ribbon-type trademark printing machine. Among them, sizing the fabric makes the fabric more firm and durable. With the enhancement of people's health awareness, developing green and beneficial functional textiles has become a development trend. In the production process of the existing mosquito-proof trademark tape, a roll of base material is coated with a mosquito-proof coating by a wet coater, dried and then cut into pieces or wound up. However, when sizing the trademark ribbon, the trademark ribbon is not flat enough and not in a taut state, resulting in a poor sizing effect when sizing the trademark ribbon.

Detailed Embodiment

[0020] The following further elaborates on the present utility model in conjunction with the accompanying drawings.

[0021] This specific embodiment is merely an interpretation of the present utility model and is not a limitation thereof. After reading this specification, those skilled in the art can make modifications without creative contributions to this embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.

[0022] Embodiment: As Figure 1 and Figure 2 shown, a wet coating device for a mosquito - proof trademark tape includes: a machine base 1, an unwinding mechanism 2 arranged at the front end of the machine base 1, a slurry tank 3 arranged behind the unwinding mechanism 2, and a slurry scraping mechanism 4 arranged above the slurry tank 3. The unwinding mechanism 2 includes an unwinding shaft and a driving motor for driving the unwinding shaft to rotate.

[0023] As Figure 3 shown, the slurry tank 3 is provided with a front redirecting roller 5, a rear redirecting roller 6, and a width expanding roller 7. The front redirecting roller 5 and the rear redirecting roller 6 are arranged front - to - back, and the width expanding roller 7 is arranged between the front redirecting roller 5 and the rear redirecting roller 6. The diameter of the width expanding roller 7 gradually decreases from the middle to both ends, that is, the width expanding roller 7 is a drum - shaped roller. When the trademark tape passes through the surface of the width expanding roller 7, the trademark tape will be stretched to both sides. At the same time, the width expanding roller 7 is an eccentric roller, that is, the roller shaft of the width expanding roller 7 does not coincide with the center line of the width expanding roller 7. When the width expanding roller 7 rotates, it will periodically squeeze the trademark tape, causing the trademark tape to be stretched in the front - to - back direction.

[0024] The spreading roller 7 is movably arranged in the slurry tank 3, and buffer mechanisms 8 are arranged at both ends of the spreading roller 7. The buffer mechanism 8 includes a fixed seat 801 fixed on the inner wall of the slurry tank 3, a sliding groove 802 vertically arranged on the fixed seat 801, a buffer frame 803 with both ends slidably installed in the sliding groove 802, and a buffer spring 804 arranged between the buffer frame 803 and the upper end of the sliding groove 802. The spreading roller 7 is rotatably installed on the buffer frame 803. Due to the eccentric rotation of the spreading roller 7, the tension of the trademark tape changes accordingly. When the tension exceeds the elastic force of the spring, the spreading roller 7 receives a downward pressure and moves downward, thereby protecting the trademark tape and preventing the tension of the trademark tape from being too large.

[0025] A stirring roller 9 is arranged at the bottom of the slurry tank 3. The stirring roller 9 is arranged below the trademark tape and is arranged parallel to the spreading roller 7. The surface of the stirring roller 9 is provided with blades spirally wound. The stirring roller 9 is driven to rotate by a separate motor, so that the slurry at the bottom of the slurry tank 3 flows in the left-right direction, preventing the slurry from settling.

[0026] As Figure 4 shown, the slurry scraping mechanism 4 includes a bracket 401, a pair of pressure rollers 402 arranged on the bracket 401, and a pair of scraping blades 403 arranged above the pressure rollers 402. The bracket 401 is fixed behind the slurry tank 3, and the pressure rollers 402 are arranged above the rear redirecting roller 6. One of the pressure rollers 402 can move back and forth relative to the other pressure roller 402, and the roller shaft of the pressure roller 402 is driven to move by a cylinder or a bolt.

[0027] The scraping blades 403 are movably arranged on the bracket 401, and the distance between the two scraping blades 403 is adjusted by an adjusting mechanism 404.

[0028] The adjusting mechanism 404 includes an adjusting seat 4041 fixed on the bracket 401, a moving seat 4042 slidably installed on the adjusting seat 4041, and an adjusting screw 4043 connected between the moving seat 4042 and the adjusting seat 4041. The scraping blade 403 is fixed on the moving seat 4042. The adjusting screw 4043 is screwed on the adjusting seat 4041 and one end is rotatably installed on the moving seat 4042. The moving direction of the scraping blade 403 is obliquely downward and points to the pressure roller 402. The thickness of the trademark tape coating is controlled by adjusting the relative distance between the two scraping blades 403.
