In the prior art, although the cloth 014 and the electrochemical aluminum film 013 are provided with the tensioning wheels (or tensioning adjusting rollers) to adjust the tightness degree of the cloth and the electrochemical aluminum film 013, at the moment that the cloth is heated and pressed, the extension length of the cloth at the discharge side of the roller is smaller than the length between the roller 09 and the cloth winding roller 011, so that the slight extension amount is not enough to trigger the tensioning wheels to adjust; in addition, because the cloth of the feed side of roller and the roller ejection of compact side all use the take-up pulley of two differences to carry out the regulation of elasticity, but because the effect of compression roller 0110, make the pulling force of roller feed side and roller ejection of compact side department cloth 014 unbalanced, thereby make the rate of tension inconsistent of roller feed side and roller ejection of compact side cloth, thereby lead to the condition that the cloth can vibrate to appear, and the ductility of electrochemical aluminium membrane receives the temperature influence less, and then lead to the position of electrochemical aluminium membrane and cloth to appear the deviation, lead to cloth and electrochemical aluminium membrane laminating precision to receive the influence, and then it makes gilt precision low to appear the deviation in gilt.
In the use process of the rapid cloth gold stamping equipment, after the press roller is contacted with the roller, if the cloth is required to keep the same running speed, the tension on the cloth needs to be increased, and the ductility of the cloth is further improved after the roller is heated, so that the length of the discharge side of the cloth is relatively long. The gilding press of the invention can downwards extrude the first guide roller when the tension of the discharge side of the roller is increased, so that the first connecting rod can downwards rotate along the connecting shaft, the first guide roller can increase the space between the press roller and the cloth winding roller in the process of downwards rotating, so that the cloth is in a tensioning state, meanwhile, the first connecting rod drives the second connecting rod to upwards move, the second connecting rod drives the driving rod to downwards rotate on the base when upwards moving, so that the linkage rod and the mounting rod are driven to downwards move, and the second guide roller is driven to downwards move, so that the cloth at the feed side of the roller is downwards extruded, the tension of the cloth at the feed side of the roller is increased, the contact surface between the cloth and the roller is increased, so that the cloth at the feed side of the roller is heated in advance, on one hand, when the second guide roller downwards moves, the tension of the cloth on the feeding side of the roller is increased, so that the stress of the cloth on the feeding side and the stress of the cloth on the discharging side of the roller are uniform, the stretching degree of the cloth is consistent, the cloth on the feeding side of the roller and the cloth on the discharging side of the roller form synchronous adjustment, a balance state is achieved, the problem that the running speed of an alumite is inconsistent due to inconsistent tension degrees of the cloth on the feeding side and the discharging side of the roller in the prior art is solved, and the purpose of improving the gold stamping precision is achieved.
Meanwhile, the tension degree of the cloth on the feeding side and the discharging side of the roller can be automatically adjusted along with the difference between the pressure of the pressing cylinder and the extensibility of the cloth, and compared with the prior art that a manual adjustment mode is adopted according to different pressing cylinder pressures and different cloths, the tension degree of the cloth on the feeding side and the discharging side of the roller does not need manual adjustment, the manual adjustment time and cost are saved, and the production efficiency is improved.
The second guide roller can contact and heat the cloth with the roller in advance while downwards extruding the cloth, so that the electrochemical aluminum film can be preheated when the cloth is contacted with the electrochemical aluminum film, the time for synchronous operation of the subsequent electrochemical aluminum film and the cloth is shortened, and the aim of improving the gold stamping speed is fulfilled. More importantly, let the cloth carry out the contact heating with the roller in advance, can let the ductility that the cloth received the temperature influence release in advance, utilize second guide roll downstream to eliminate the change of the rate of tension that the cloth received to bring after the temperature extension to make the rate of tension of roller feeding side and roller ejection of compact side unanimous.
In some embodiments, the base 098 is further provided with a third guide roller 0913 for preventing the second U-shaped frame from blocking the cloth during the movement, thereby preventing the interlocking mechanism from contacting the cloth 014 during the movement and ensuring the normal rotation of the cloth 014.
In some embodiments, a limiting groove 0914 is installed on the inner wall of the through groove, a protrusion 0910 which is matched with the limiting groove 0914 is installed on the periphery of the mounting rod 099, the protrusion 0610 extends into the limiting groove 0914 and can slide up and down in the limiting groove 0914, and a spring 0911 for delaying the running speed of the mounting rod 099 in the through groove is installed between the protrusion 0910 and the bottom of the limiting groove 0914.
