Description

Technical Field

[0001] This utility model relates to the field of coated paper processing technology, specifically a coated paper trimming device with a rotating structure. Background Technology

[0002] Coated paper is paper with a plastic slurry coated on its surface. Plastic particles are coated onto the paper surface using a doctor blade in a casting machine. After curing, a thin film is formed to protect the paper surface, giving it waterproof and oil-proof properties. It can be used for food packaging and also has a certain degree of heat resistance.

[0003] To ensure smooth edges of the coated paper and to facilitate cutting, a rotating blade is needed to trim the edges of the paper stack. Such trimming devices often lack a rotating mechanism. If the paper stack is rotated manually, the trimming arc will not be even, and there are also safety issues.

[0004] Now, a novel edge trimming device for coated paper with a rotating structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a paper trimming device with a rotating structure to solve the problem of lack of rotating function mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coating paper trimming device with a rotating structure, comprising a substrate and a slot. The upper part of the substrate is provided with a slot, and a limit rod is fixed between the two sides inside the slot. A movable seat is movably sleeved on the outside of the limit rod, and ball bearings are respectively embedded on both sides of the bottom of the movable seat. A bolt is threadedly connected to the lower center of the front end of the movable seat. A worm gear is movably connected to the top of the movable seat, and a plate is fixed to the top of the worm gear. A stack of paper is placed on the top of the plate. A fixing frame is installed on the right side of the movable seat, and a motor is fixed to the front end of the fixing frame. A worm gear is movably connected between the front and rear of the fixing frame.

[0007] As a further technical solution of this utility model, the movable seat slides left and right along the surface of the limiting rod, the worm gear is meshed and connected to the left side of the worm, and the output shaft of the first motor is fixedly connected to the front of the worm.

[0008] As a further technical solution of this utility model, the front and rear surfaces of the flat plate are respectively provided with transverse grooves, and a slider is movably connected in the transverse grooves. A bottom block is fixed to the outside of the slider, and a thin rod is fixed to the bottom end inside the bottom block. A sleeve is movably sleeved on the outside of the thin rod, and a spring is fixed between the bottom of the sleeve and the bottom block. A pressure plate is fixed between the front and rear ends of the top end of the sleeve, and a handle is fixed at the center of the top end of the pressure plate.

[0009] As a further technical solution of this utility model, the spring is supported between the sleeve and the bottom block, and the slider slides left and right along the inner wall of the transverse groove.

[0010] As a further technical solution of this utility model, a bracket is fixed on the left side of the top of the base plate, and a left cylinder is fixed on the left side of the top of the bracket. A connecting frame is fixed at the bottom of the piston rod of the left cylinder, and a motor three is fixed at the front end of the connecting frame. A hanger is movably connected between the front and rear of the inside of the connecting frame, and a motor two is fixed on the left side of the outside of the hanger. A blade is movably connected between the two sides inside the hanger. A right cylinder is fixed on the right side of the top of the bracket, and a limit plate is fixed at the bottom of the piston rod of the right cylinder.

[0011] As a further technical solution of this utility model, the right side of the output end of the second motor is fixedly connected to the blade, and the rear of the output end of the third motor is fixedly connected to the hanger.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the coated paper trimming device with a rotating structure not only realizes the adjustment of paper direction and the prevention of paper stack movement, but also realizes the adjustment of the cutting mechanism;

[0013] (1) By fixing a plate at the top of the worm gear, the paper stack is placed on the top of the plate. Under the lubrication of the ball, the position of the moving seat is adjusted along the limit rod and locked with bolts. Then, the motor is turned on and the worm is rotated in the fixed frame, forcing the worm to mesh and push the worm gear on the left side, guiding the worm gear and the plate at its top to rotate. The paper stack is rotated below the blade and the limit plate, waiting for the paper to be trimmed.

[0014] (2) By fixing a pressure plate between the front and back of the top of the sleeve, the paper stack of coated paper is placed on the flat plate. After holding the handle, the slider and sleeve are moved along the sliding grooves at the front and back. The distance between the pressure plate and the bottom block is adjusted according to the thickness of the paper stack. After the spring releases the handle, it quickly drives the sleeve to sink along the thin rod, forcing the pressure plate to stick to the top of the paper stack for fixation. The fixation position can be adjusted.

[0015] (3) The blade is connected between the two sides inside the hanger. When the blade approaches the left side of the paper stack, the right cylinder uses the piston rod to lower the limit plate and flatten the paper stack to prevent the paper from sticking up. Then, the motor three is turned on to adjust the angle of the hanger left and right in the connecting frame, and the blade in the hanger is rotated by the motor two to trim the left side of the rotating paper stack. As the paper stack of the flatbed machine rotates, the limit plate also rises and falls continuously to avoid affecting the rotation of the machine. Attached Figure Description
