Description

Technical Field

[0001] This invention relates to a paper cutter, specifically a fully automatic circular saw paper cutter. Background Technology

[0002] The printing process includes pre-press processing, printing, and post-press processing. Post-press processing generally refers to the finishing of printed materials, including lamination, embossing, coating, die-cutting, hot stamping, debossing, mounting, binding, and cutting. A paper cutter is a device used to handle the paper cutting needs of post-press processing. Currently, Chinese utility model patent CN214652526U discloses a paper feeding mechanism for a paper cutter, including a paper cutter body. A placement platform is fixedly connected to one side of the paper cutter body. The upper surface of the placement platform has scale lines, and the lower surface of the placement platform is symmetrically fixedly connected to a support leg. The upper surface of the placement platform is symmetrically fixedly connected to a guide mechanism, which is equipped with a push-limiting component. The push-limiting component and the guide mechanism are slidably connected by a sleeve. The push-limiting component includes a push plate and a guide plate. The bottom end of the push plate is provided with a guide plate, and the guide plate and the push plate are fixedly connected by welding. The paper to be cut can be clamped and fixed by the cooperation between the push limit component, clamping plate and locking threaded cylinder, thus avoiding the paper tilting when feeding. The push limit component and guide mechanism can make the push of the push limit component more convenient and stable.

[0003] Stacked paper is manually placed on the push plate. However, stacked paper often becomes misaligned, requiring manual manipulation using tools to push the opposite sides of the paper to make the stack neat for cutting. This process is labor-intensive and time-consuming. Therefore, this application designs a fully automatic circular saw paper cutter. Summary of the Invention

[0004] The main purpose of this disclosure is to provide a fully automatic circular saw paper cutter to effectively solve the problems raised by the inventors in the background art mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A fully automatic circular saw paper cutter includes a machine table, a frame fixedly installed at the bottom of the machine table, and a material drop box fixedly installed on the frame. A cutting opening is provided at the top of the machine table, and the cutting opening leads into the material drop box.

A sawing motor is fixedly installed on the side of the U-shaped support, and reduction gears are fixedly installed at the output end of the sawing motor and on the rotating shaft. The two reduction gears mesh with each other for transmission, and the circular saw blade is located directly above the cut.

[0007] Preferably, the diameter of the reduction gear on the rotating shaft is larger than the diameter of the reduction gear on the output end of the sawing motor.

[0008] Preferably, the paper positioning mechanism includes a curved lever, a forked cylinder, a paper pressing block, a guide block, a Z-axis sliding shaft, a support spring, and a smooth contact block. The curved lever is fixedly installed at the bottom of the platform, and the forked cylinder is fixedly installed at the other end of the curved lever. The paper pressing block is slidably installed inside the forked cylinder and is located above the paper to be processed. The guide block is fixedly connected to the side of the platform, and the Z-axis sliding shaft is slidably installed through the guide block. The bottom end of the Z-axis sliding shaft movably passes through the forked cylinder and is fixedly connected to the paper pressing block. The top end of the Z-axis sliding shaft is fixedly connected to the smooth contact block. The top of the forked cylinder is fixedly connected to the support spring, and the other end of the support spring is fixedly connected to the surface of the Z-axis sliding shaft. The body of the support spring is sleeved on the Z-axis sliding shaft.

[0009] Preferably, the bottom of the horizontal mounting plate is provided with a plurality of evenly distributed rolling grooves, and rolling balls are movably installed in the rolling grooves, with the rolling balls located above the smooth contact block.

[0010] Preferably, the paper powder treatment mechanism includes a drive shaft, a crushing toothed roller, a driven shaft, a conveyor wheel, a material distribution conveyor belt, and a collection box. Two symmetrically arranged drive shafts are rotatably installed at the upper end of the discharge box, and a crushing toothed roller is fixedly installed on the drive shaft. Four driven shafts of equal height are rotatably installed in the discharge box, and a conveyor wheel is fixedly installed on the driven shaft. The two conveyor wheels on both sides are connected by a material distribution conveyor belt. The two crushing toothed rollers rotate in opposite directions, and the two material distribution conveyor belts drive in opposite directions. A collection box is slidably installed on the side of the discharge box, and the collection box is located below the material distribution conveyor belt.

[0011] Preferably, a crushing motor is fixedly installed on the front of the material box, and the output end of the crushing motor is fixedly connected to one of the driving shafts.

[0012] Preferably, a number of evenly distributed side pads are fixedly installed on the top of the machine table, and the paper to be processed is located between the front and rear side pads. A length stop key is installed on the right side of the top of the machine table.

[0013] In view of this, compared with the prior art, the beneficial effects of the present invention are: (i) In this application, the paper to be processed is placed on the top of the machine table and between the front and rear guide frames and the front and rear side pads to guide the paper to be processed and prevent it from deviating from the cut on the machine table, so that it can be accurately placed under the circular saw blade.

[0014] (ii) In this application, before sawing, the right side of the paper to be processed is placed against the length stop key. The sawing working motor and the Z-axis electric push rod drive one of the reduction gears to rotate. Under the meshing transmission with the other reduction gear, the rotating shaft drives the circular saw to rotate. The Z-axis electric push rod drives the lifting gantry to move downward, so the sawing mechanism is moved downward, so that the rotating circular saw performs sawing operation on the paper to be processed. The automated operation is stable and the efficiency is improved. The sawing waste falls into the material box through the cut for processing, avoiding material waste.

[0015] (III) In this application, when the horizontal mounting plate moves downward, the rolling ball on it will press against the smooth contact block, causing the Z-axis sliding axis to move downward, the support sleeve spring is stretched, and the paper pressure block moves downward in the bifurcation cylinder and presses on the paper to be processed, further restricting the movement of the paper to be processed, improving the processing accuracy, and automatically positioning before sawing. The design is novel and reasonable.

[0016] (iv) In this application, after the waste enters the discharge box, the crushing motor starts, causing the drive shaft to drive the crushing toothed roller to rotate. Under the meshing of the first alignment gear, the two crushing toothed rollers rotate in opposite directions to achieve the crushing of the waste. The processed waste falls into the collection box or the distribution conveyor belt. Under the rotation of the linkage sprocket and the transmission chain, the driven shaft rotates together with the drive shaft. That is, the distribution conveyor belt will carry the processed waste to the collection box, so that the waste can be transported step by step. Attached Figure Description

The processed waste material falls into the collection box 25 or onto the distribution conveyor belt 24. Under the rotation of the linkage sprocket 29 and the transmission chain 30, the driven shaft 23 rotates together with the drive shaft 21. That is, the distribution conveyor belt 24 will carry the processed waste material to the collection box 25, so that the waste material can be transported step by step.
