Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to an adjustable wheel set of a coating machine. Background Art

[0002] With the rapid development of mechanical automation, the application of roller coaters is becoming more and more widespread. The full name of roller coater is roller coater. It is a device that uses one or more rotating rollers to apply a certain amount of paint to a flat material. The coating thickness can be adjusted by changing the pressure between the two rollers.

[0003] There are many guide wheel groups, namely guide rollers, on the coating machine. The guide rollers provide guidance for the cloth. The material selection of the guide rollers depends on the specific application scenarios and process requirements. Common materials include metal, rubber, polyurethane, etc. When producing different cloths, it is necessary to replace the roller material according to the needs. The existing technology directly replaces the entire guide roller. The present invention designs a roller body that can replace the material of the external part that is in direct contact with the cloth, and can adjust the position of the roller body to fit the cloth well. This design can save production costs. Utility Model Content

[0008] Preferably, the connecting flange is fixedly connected to the coating machine body by screws.

[0009] Preferably, a bolt sleeve is provided on the inner wall of the sleeve, and the screw-in end of the bolt is inserted into the bolt sleeve.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The utility model provides an adjustable wheel set for a coating machine, which can meet the production requirements of different fabrics by replacing different outer roller bodies, which is more cost-effective than replacing the entire roller body, and an adjustment mechanism is provided to enable the replaced outer roller body to fit well with the fabric.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 A coating machine adjustable wheel set includes a main core column 1, connecting flanges 2 are integrally formed at both ends of the main core column 1, a sleeve 6 is sleeved on the outside of the main core column 1, a threaded hole 3 is provided on the main core column 1, and a through hole is correspondingly provided on the sleeve 6. A bolt 4 is threadedly inserted into the threaded hole 3, and the outer end of the bolt 4 passes through the through hole. The bolt 4 is located at the outer end of the sleeve 6 and is threadedly sleeved with a locking nut 5. A bolt sleeve 9 is provided on the inner wall of the sleeve 6, and the screw-in end of the bolt 4 is inserted into the bolt sleeve 9. The depth of the bolt 4 screwed into the threaded hole 3 can be adjusted by rotating the bolt 4. The end of the bolt 4 presses against the sleeve 6 and pushes the sleeve 6 to a position deviating from the axis of the main core column 1.

[0018] The sleeve 6 is rotatably connected to the outside with an outer roller 8. When the outer roller 8 rubs against the fabric for a long time, it will cause the outer roller 8 to become thinner. By deviating the sleeve 6 from the axial position of the main core column 1, the outer diameter of the outer roller 8 can be compensated for, so that the fabric can always fit the outer roller 8.

[0019] The sleeve 6 has bearings 7 at both ends thereof, and the two are interference fit. The outer side of the bearing 7 and the inner wall of the outer roller 8 are interference fit. The outer roller 8 and the sleeve 6 are connected by the bearing 7, and the rotation damping is small, which facilitates movement.

[0020] The connecting flange 2 is fixedly connected to the coating machine body through screws, and the entire device is fixedly installed on the coating machine through the connecting flange 2 to serve as a cloth guide roller.

[0021] Working principle: The guide roller provides guidance for the fabric. The material selection of the guide roller depends on the specific application scenario and process requirements. Common materials include metal, rubber, polyurethane, etc. When producing different fabrics, it is necessary to replace the roller material according to the needs. The utility model can achieve the above goal by replacing different outer roller bodies 8. The depth of the bolt 4 screwed into the threaded hole 3 can be adjusted by rotating the bolt 4. The end of the bolt 4 abuts against the sleeve 6 and pushes the sleeve 6 to a position deviating from the axis of the main core column 1 to compensate for the reduction in the outer diameter of the outer roller body 8, so that the fabric can always fit the outer roller body 8. When the diameter of the outer roller body 8 is larger than before, the bolt 4 is rotated in the opposite direction.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
