Description

Technical Field

[0001] This invention relates to the field of decorative paper technology, and in particular to a two-stage tensioning system for an impregnation dryer. Background Technology

[0002] Impregnated paper / fabric is made from a mixture of non-woven wood pulp, PE, and plant fibers. It has super absorbency and solvent resistance, and is wear-resistant, available in a variety of styles, impact-resistant, deformation-resistant, stain-resistant, flame-retardant, moisture-proof, environmentally friendly, colorfast, easy to install, and easy to maintain. It is widely used as a veneer for cabinets, wardrobes, and engineered wood flooring. Impregnated paper / fabric is produced by coating melamine glue and some additives onto the veneer paper / fabric using an impregnation coating machine. After impregnation, the paper / fabric needs to be dried. However, because the paper / fabric is relatively soft and the drying box has a large span, it is easy for it to loosen or sag inside the drying box. At the same time, an excessively long drying box can also cause the paper / fabric to carbonize during the drying process, seriously affecting the quality of the impregnated paper / fabric. Summary of the Invention

[0015] The intermediate roller assembly includes an intermediate movable roller 42 and an intermediate fixed roller 43.

An intermediate hinge plate 44 is movably hinged to the intermediate roller rod. An intermediate roller plate cylinder is hinged to the transfer frame 34.

The bottom of the suspended end is hinged to the intermediate adjusting cylinder 46, and the other end of the intermediate adjusting cylinder 46 is inclined downward and hinged to the transfer frame 34. The intermediate output adjusting roller 45 is installed on the top of the suspended end.

[0016] The output tensioning unit includes a first tensioning roller 27, a second tensioning roller 28, a first power roller 29, and a second power roller 30. The first tensioning roller 27 and the second tensioning roller 28 are installed parallel to each other on the frame 1 in the output direction of the filtrate tank, forming a traction zone between them. The first power roller 29 and the second power roller 30 are installed above the traction zone. A pressure regulating cylinder 31 is installed vertically on the frame 1 above the traction zone. The piston rod of the pressure regulating cylinder 31 is connected downward to the conveying lifting frame 32. The first power roller 29 and the second power roller 30 are respectively installed at both ends of the bottom of the conveying lifting frame 32 and are connected by a friction belt 33. A traction motor is installed on the conveying lifting frame 32, and a drive pulley is installed on the drive shaft of the traction motor. A driven pulley is installed at one end of the second power roller 30, and the driven pulley is connected to the drive pulley by a transmission belt.

[0017] The traction force adjustment unit includes a traction force adjustment cylinder 16, an output tension roller 17, and an output adjustment roller plate 18. One end of the output adjustment roller plate 18 is hinged to the traction frame above the traction output roller 12. The output tension roller 17 is installed at the lower part of the other end of the output adjustment roller plate 18. The output adjustment roller plate 18 above the output tension roller 17 is hinged to one end of the traction force adjustment cylinder 16. The other end of the traction force adjustment cylinder 16 is hinged upward to the traction frame. The installed traction output roller 17 is located above the traction output roller 12.

[0018] A conveying tension zone is formed between the first tension roller and the second tension roller, and the drive belt is located above the conveying tension zone; during conveying, the paper / cloth after impregnation is supported by the first tension roller and the second tension roller and sent to the first drying section;

[0019] The piston rod of the pressure regulating cylinder drives the conveyor lifting frame to move downward. The conveyor lifting frame simultaneously drives the first power roller and the second power roller to move downward, so that the friction belt presses on the paper / cloth surface of the conveying tension zone. The traction motor drives the friction belt to rotate. Through the friction force generated between the friction belt and the paper / cloth, the paper / cloth is conveyed backward.

[0020] After the paper / cloth undergoes its first drying in the first drying section, it enters the intermediate tensioning unit and is then fed into the second drying section. When the tension of the paper / cloth in the first and second drying sections is maintained at a good level (the tension remains consistent), the piston rod of the tension cylinder retracts, driving the movable end of the transmission roller frame to move upward, and the front fixed roller and the rear adjusting roller leave the paper / cloth and do not contact it.

[0021] The paper / cloth to be dried enters from the transfer roller, passes through the intermediate movable roller, intermediate fixed roller, and intermediate output adjusting roller, and is then output; the suction fan draws air as needed to remove some of the heat from the paper / cloth, thereby preventing the paper / cloth from carbonizing;

[0022] When the tension of the paper / cloth needs to be fine-tuned (with a small adjustment force), the piston rod of the intermediate adjusting cylinder extends and drives the upper part of the movable end of the intermediate roller adjusting seat. When the intermediate roller adjusting seat moves upward, it simultaneously drives the intermediate output adjusting roller to move upward. When the intermediate output adjusting roller moves upward, it pushes the paper / cloth upward, and the output pressure roller begins to contact the surface of the paper / cloth. Through the cooperation of the intermediate output adjusting roller and the output pressure roller, the paper / cloth is output in a stepped manner, thereby completing the fine-tuning of the tension of the paper / cloth.

[0023] When there is a large difference in traction before and after the drying process or when the drying speed needs to be reduced, the piston rod of the tension cylinder extends, driving the movable end of the transmission roller frame downward. The front fixed roller and the rear adjusting roller begin to contact the paper / cloth surface, and press down the paper / cloth between the transfer roller and the middle movable roller, forming a tensioning.

[0024] When tensioning and deceleration are required again, the piston rod of the roller seat cylinder extends, driving the rear adjusting roller to move downward again. At the same time, the piston rod of the intermediate roller plate cylinder extends, driving the intermediate hinge plate to move upward, so that the intermediate movable roller moves upward synchronously. Through the cooperation of the rear adjusting roller and the intermediate movable roller, the paper / cloth is tensioned and decelerated again. The rear adjusting roller is driven by the corresponding roller motor. The surface of the rear adjusting roller is provided with concave and convex friction mesh, which increases the traction force of the rear adjusting roller on the paper / cloth.

[0025] After bypassing the traction input roller, second traction roller, first traction roller, and traction output roller, the paper / cloth is output using a multi-roller steering system, which effectively maintains the tension of the paper / cloth. When it is necessary to increase the traction force (tension), the piston rod of the traction force adjusting cylinder drives the movable end of the output adjusting roller plate to move. The output adjusting roller plate synchronously drives the traction output roller, and the pressure applied by the traction output roller to the second tension roller and the traction output roller changes the magnitude of the traction force (tension) of the paper / cloth.

[0026] This solution uses three sets of traction and tensioning mechanisms to keep the paper / cloth in the first and second drying sections constantly under tension, greatly increasing the drying effect and significantly improving the quality of the dried paper / cloth.

[0027] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, any changes made in accordance with the shape and principle of the present invention should be covered within the protection scope of the present invention.
