Description

Technical Field

[0002] Coating machine is a machine that quantitatively applies liquid (or melt) polymer materials such as adhesives or coatings on the surface of materials. Coating machine has the advantages of low operating threshold and convenient use, so it is widely used in various production plants.

[0003] The existing coating machine structure usually includes a coating machine housing, a cover shell is fixedly installed on the coating machine housing, a coating roller is installed inside the cover shell, and a conveyor belt is connected to the top surface of the coating machine housing. The coating roller abuts against the conveyor belt. When in use, the coating roller is stained with the dye to be tested, and the coated part to be tested is placed on the conveyor belt and abuts against the coating roller under the conveyor belt. The coating roller presses the coated part and drives the coated part to pass under the coating roller by rolling, thereby completing the coating process.

[0004] The above prior art has the following defects:

[0005] The coating amount of the coating machine can be adjusted by the pressure between the metering rollers. When the pressure is increased, the amount of coating passing through is reduced, and the coating amount is also reduced. However, due to the lack of a positioning structure for the part to be coated, the coating roller applies force to the coating surface, which can easily cause the part to be coated to shift on the conveyor belt after being subjected to force, thereby affecting the coating effect.

[0026] See also Figure 1-4 As shown, a long strip-shaped constraint plate 6 is provided at a position of the pressing frame 2 away from the coating roller.

[0028] A specific application of this embodiment is:

[0029] Before the coating operation, the staff first adjusts the distance between the two constraint plates 6 through the operation port. Through the reading display of the scale line 8, the staff adjusts the distance between the two constraint plates 6 to the size of the coated piece. After the adjustment is completed, the clamping cylinder 21 drives the clamping frame 2 to move in the direction of the conveyor belt 12 through the extended telescopic rod 22. At the same time, the guide rod 42 moves synchronously in the lifting groove 43. When the adhesion roller 31, the anti-static roller 41 and the locking roller abut against the conveyor belt 12 and rotate synchronously with the conveyor belt 12, the guide rod 42 abuts against the ground at the same time. The state between the guide rod 42 and the ground can reflect the movement state of the clamping frame 2, which is convenient for the worker to stop the work of the clamping cylinder 21 in time.

[0030] When the coating test of the coated piece is carried out, the coated piece moves to the position of the pressing frame 2 under the conveying action of the conveyor belt 12, and the two restraining plates 6 restrain the two sides of the coated piece. When the coated piece moves to the bottom of the pressing frame 2, the coated piece first contacts the adhesive roller 31, and the adhesive roller 31 sticks the dust on the surface of the coated piece. At the same time, the adhesive roller 31 presses and restrains the coated piece through the viscosity. After passing the adhesive roller 31, the coated piece contacts the anti-static roller 41, and the anti-static roller 41 conducts part of the static electricity on the coated piece to the guide rod 42, and eliminates the static electricity through the guide rod 42, and the other part is transmitted to the ground through the coating machine housing, reducing the static electricity on the surface of the coated piece. Finally, the coating piece contacts the locking roller 51. The material characteristics of the locking roller 51 increase the friction between the locking roller 51 and the coating piece, preventing the coating piece from sliding under the locking roller 51. When the coating piece moves, the adhesion roller 31, the anti-static roller 41 and the locking roller 51 roll with the coating piece. After the coating piece is transported to the bottom of the coating roller, the coating roller contacts the coating piece and applies pressure to perform the coating work. In summary, through the above steps, the effect of preventing the coating piece from being offset on the conveyor belt after being subjected to force is achieved.

[0031] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should fall within the protection scope of the present invention.
