Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coating machines, in particular to a material coil spring self-adjusting pressure roller structure. Background Art
[0002] During the coating machine's winding process, a pressure roller is often used to assist with the final winding of the material to ensure tightness and evenness of the end surface. The material width typically reaches 1650mm, but the thickness of the material cannot be completely consistent across the entire 1650mm width. As the roll continues to grow, one side may become slightly larger. If the pressure roller cannot adapt to this change and forcibly tries to flatten the roll, the material will typically wrinkle. Utility Model Content
[0003] The purpose of the utility model is to provide a coil spring self-adjusting pressure roller structure to solve the problems raised in the above background technology.
[0004] In view of the above problems, the technical solution proposed by the present invention is:
[0005] The cam is secured to the upper and lower surfaces of the cam, and the cam is secured to the lower surface of the cam, and the cam is secured to the lower surface of the cam.
[0006] The beneficial effect of adopting the above-mentioned further scheme is that the material is wound up by the reel, and the rubber pressure roller presses the material to ensure the tightness of the material roll and the neatness of the end surface. When the radius of one end of the material roll is larger due to uneven thickness of the material, this end will squeeze the rubber pressure roller. Through the use of sliding ejector pins, the pressure exerted on the rubber pressure roller will be transmitted to the core shaft, so that the ejector pins in the same direction as the pressure will retreat, and the angle of the rubber pressure roller will adapt to the size change of the material roll. At the same time, the use of six groups of first springs can make the six groups of ejector pins always squeeze the core shaft, ensuring that the rubber pressure roller can remain stable after the angle changes, thereby ensuring that the rubber pressure roller can always press the material.
[0007] The beneficial effects of adopting the above further solution are that the screw firstly ensures that the first spring can squeeze the ejector pin, and secondly, when the screw rotates, it can change the compression amount of the first spring to adjust the elasticity of the first spring.
[0008] Furthermore, locking rings are installed at both ends of the core shaft, nuts are threadedly engaged at both ends of the core shaft, second springs are sleeved at both ends of the core shaft, and the two ends of the second spring squeeze the fixing plate and the nut respectively.
[0009] The beneficial effect of adopting the above further solution is that the locking ring prevents the bearing from moving, the second spring can prevent the core shaft from moving left and right, and the nut can change the compression of the second spring to adjust the elasticity of the second spring. Furthermore, the drive locking member includes a pair of gears mounted at both ends of the rotating shaft and a support seat mounted on the side of a pair of the discs. The top surface of the support seat is slidably connected to a rack, and the gear and the rack are meshed. A cylinder is mounted on the outside of the support seat, and the telescopic end of the cylinder is connected to the rack.
[0010] The beneficial effect of adopting the above further solution is that the rack is driven to move by the cylinder, so that the gear drives the rotating shaft to rotate to change the distance between the pressure roller and the reel. Because the material becomes thicker as it is rolled on the reel, this method can ensure that the position of the pressure roller adapts to the radius of the material roll.
[0011] Specifically, the extension of the cylinder is controlled by a PLC controller.
[0012] Furthermore, a counterweight is installed on the outside of the rotating shaft.
[0013] The beneficial effect of adopting the above further scheme is that, with the axis of the rotating shaft as the center line, the center of gravity of the counterweight block is located on one side of the center line, while the center of gravity of the pressure roller mechanism is located on the other side of the center line, so that the force exerted by the rubber pressure roller on the material roll can be kept stable.
[0014] Furthermore, a pair of cross braces are installed between the pair of discs, a pair of support arms are installed on the sides of the pair of cross braces, and the reel is installed between the pair of support arms through a bearing.
[0015] Furthermore, a motor is installed on the side of one of the support arms, and the output end of the motor is transmission-connected to the reel.
[0016] The beneficial effect of adopting the above further solution is that the motor is used to drive the reel to rotate, thereby completing the winding of the material.
[0017] Compared with the prior art, the beneficial effects of the present invention are: the material roll spring self-adjusts the pressure roller structure, and the material is wound up by the reel, while the rubber pressure roller presses the material to ensure the tightness of the material roll and the neatness of the end surface. When the material roll has a larger radius at one end due to uneven material thickness, this end will squeeze the rubber pressure roller. Through the use of sliding ejector pins, the pressure exerted on the rubber pressure roller will be transmitted to the core shaft, so that the ejector pin in the same direction as the pressure will retreat, and then the angle of the rubber pressure roller will adapt to the size change of the material roll. At the same time, the use of six groups of first springs can make the six groups of ejector pins always squeeze the core shaft, ensuring that the rubber pressure roller can remain stable after the angle changes, thereby ensuring that the rubber pressure roller can always press the material.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] See also Figure 1 - Figure 3The utility model provides a technical solution: a material roll spring self-adjusting pressure roller structure, the driving locking member includes a pair of gears 2006 installed at both ends of the rotating shaft 2002, and a support base 2003 installed on the side of a pair of discs 1001. The top surface of the support base 2003 is slidably connected with a rack 2004, and the gear 2006 and the rack 2004 are engaged and connected. A cylinder 2005 is installed on the outside of the support base 2003, and the telescopic end of the cylinder 2005 is connected to the rack 2004.

During this process, the cylinder 2005 drives the rack 2004 to move, so that the gear 2006 drives the rotating shaft 2002 to rotate, so as to change the distance between the rubber pressure roller 3002 and the reel 1004. Because the material becomes thicker as it is rolled on the reel 1004, in this way, it can be ensured that the rubber pressure roller 3002 always presses the material roll to ensure the tightness of the material roll and the end face. Evenness: When the material roll has a larger radius at one end due to uneven material thickness, this end will squeeze the rubber pressure roller 3002. Through the use of the sliding ejector pin 3007, the pressure on the rubber pressure roller 3002 will be transmitted to the core shaft 3001, so that the ejector pin 3007 in the same direction as the pressure will retreat, and then the angle of the rubber pressure roller 3002 will adapt to the size change of the material roll. At the same time, the use of six groups of first springs 3008 can make the six groups of ejector pins 3007 always squeeze the core shaft 3001, ensuring that the rubber pressure roller 3002 can remain stable after the angle changes, thereby ensuring that the rubber pressure roller 3002 can always press the material.
