[0002] In the current production process, the edge banding strip needs to be wound up after extrusion and stretching. In order to protect the surface of the edge banding strip from scratches during subsequent processing, a protective material is applied to the outer surface of the edge banding strip before winding. The current application method uses a small coating roller. Since the edge banding strip is not absorbent, the protective material is only applied to the surface, and it is easy for it to flow down from the top surface of the edge banding strip and onto the rollers and equipment below. If it is not cleaned in time, the edge banding strip will become very dirty, and the production environment will be quite bad. Therefore, a technical solution is needed to solve the above problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this embodiment discloses a sealing strip coating device, including a coating mechanism 1 and a discharging mechanism 2. The coating mechanism 1 includes an applicator roller 11, two support rollers 12, and two support seats 13. The applicator roller 11 and the support rollers 12 are rotatably mounted between the two support seats 13. The applicator roller 11 and the support rollers 12 are rotatable and are driven to rotate by motors. The two support rollers 12 are arranged in parallel and spaced apart. The applicator roller 11 is located above the two support rollers 12. The applicator roller 11 includes an applicator groove 111. The diameter of the applicator groove 111 is smaller than the maximum diameter of the support roller 12. The coating groove 111 is recessed into the coating roller 11, and the width of the inner surface of the coating groove 111 is the same as the width of the sealing strip 6. The sealing strip 6 passes between the coating roller 11 and the support roller 12. The two support rollers 12 support the lower surface of the sealing strip 6, and the coating groove 111 abuts against the upper surface of the sealing strip 6. The lowest end of the coating groove 111 is at the same height as the support roller 12, so that the portion of the sealing strip 6 passing through the coating groove 111 and the two support rollers 12 is pressed down by the coating roller 11 and bent downward. The coating roller 11 and the sealing strip 6 interact with each other, so that the coating groove 111 fits tightly against the upper end surface of the sealing strip 6, which can better coat the sealing strip 6.

[0023] The dispensing mechanism 2 is located above the coating roller 11. The dispensing mechanism 2 includes a hopper 21, a clamp 22, and a coating sheet 23. The clamp 22 includes a main body 221 and a clamping plate 222. The hopper 21 has an upward-opening inlet 211 through which the coating liquid can be replenished. The clamping plate 222 is hinged to the main body 221, and part of the main body 221 is located inside the hopper 21. The main body 221 and the clamping plate 222 can clamp the coating sheet 23. The main body 221 has a plurality of first racks 2211, which are arranged along the length of the main body 221. The clamping plate 222 has a plurality of first racks 2211. Multiple second racks 2221 corresponding to the first rack 2211. The first rack 2211 and the second racks 2221 can clamp the upper end of the smear 23. When installing, the smear 23 is placed between the first rack 2211 and the second racks 2221. The clamping plate 222 is rotated to clamp and fix the smear 23 in the clamp 22. One end of the main body 221 is provided with a locking plate 223, and one end of the clamping plate 222 is also provided with a locking plate 223. After the clamping plate 222 clamps the smear 23, it is locked and fixed by bolts. When the moisture permeability of the smear 23 deteriorates, the clamp 22 can be opened to replace the smear 23.

[0024] The main body 221 is provided with a channel 2212, which is arranged along the length of the main body 221. The channel 2212 connects the upper end face of the main body 221 and the coating sheet 23. The channel 2212 can guide the liquid in the hopper 21 to the coating sheet 23. The coating sheet 23 is made of a material with good moisture permeability. The coating sheet 23 can absorb the liquid in the hopper 21. The coating sheet 23 is partially attached to the outer surface of the coating groove 111. The wet coating sheet 23 can apply the liquid to the coating groove 111 as the coating roller 11 rotates, so that the coating roller 11 can evenly coat the sealing strip 6. More preferably, the width of the coating sheet 23 is the same as the width of the coating groove 111. A part of the coating sheet 23 is located in the coating groove 111. The two sides of the coating groove 111 are conical surfaces 112. The coating sheet 23 can be restricted and concentrated in the coating groove 111 by the conical surfaces 112 and completely cover the width of the coating groove 111.

[0025] A mounting plate 14 is installed on the upper end of the support base 13. The mounting plate 14 is provided with a first guide groove 141. The hopper 21 includes a locking rod 212. The locking rod 212 can slide along the first guide groove 141, so that the hopper 21 can move closer to or away from the applicator roller 11. The height of the hopper 21 can be fixed by locking the locking rod 212. The mounting plate 14 is provided with a second guide groove 142. The hopper 21 includes a guide rod 213. The guide rod 213 passes through the second guide groove 142 and can move along the second guide groove 142. The second guide groove 142 plays a limiting and stabilizing role for the movement of the hopper 21, preventing the hopper 21 from rotating during the movement and causing the applicator 23 to shift.

[0026] This embodiment also includes two traction devices 3, a hot air blower 4, and a baffle 5. The two traction devices 3 are located at the front and rear ends of the coating mechanism 1, respectively. The traction device 3 includes two traction rollers 31 and two fixed plates 33. The two traction rollers 31 are rotatably installed between the two fixed plates 33. The edge sealing strip 6 passes through the two traction rollers 31. The two traction rollers 31 press against the upper and lower surfaces of the edge sealing strip 6, respectively. The two traction devices 3 can straighten the edge sealing strip 6 located at the front and rear ends of the coating mechanism 1 in the horizontal direction, so that the edge sealing strip 6 can be better pulled and moved. At the same time, it can give the edge sealing strip 6 a tension force, so that the coating groove 111 fits tightly with the upper end surface of the edge sealing strip 6, and can better coat the edge sealing strip 6.

[0027] The traction device 3 located at the rear end of the coating mechanism 1 is provided with a support plate 32. The hot air blower 4 is fixedly installed on the support plate 32. The hot air blower 4 is located between the traction device 3 and the coating mechanism 1. The air outlet of the hot air blower 4 faces the upper surface of the sealing strip 6. The setting of the hot air blower 4 can accelerate the curing of the coating applied to the upper surface of the sealing strip 6. The coating can be cured completely when the sealing strip 6 contacts the traction device 3 located at the rear end. The baffle 5 is located between the hot air blower 4 and the coating mechanism 1. The baffle 5 is provided with a through hole 51 for the sealing strip 6 to pass through. The baffle 5 can block the hot air from blowing towards the coating sheet 23 and prevent the hot air from curing the coating sheet 23.
