Description

Technical Field

[0001] This utility model belongs to the technical field of packaging material processing equipment, specifically relating to a printing PS plate cutting machine. Background Technology

[0002] In the printing and packaging industry, when offset printing is performed using different models of printing presses, the pre-coated photosensitive plates (PS plates) need to be cut to the appropriate specifications in advance for easy installation and printing production. At the same time, because different models of printing presses have different requirements for the specifications of the pre-coated photosensitive plates, there are instances where cut PS plates are temporarily transferred to another printing press for production. This results in some PS plate specifications not meeting production needs. Therefore, PS plates need to be flexibly cut after publication and before being used on the printing press.

[0003] The current practice involves manually fixing the PS plate onto a flat surface and then cutting it with a utility knife. This method is inefficient, requires skilled operation, and can easily cause the plate to twist and deform if not properly fixed, also increasing the risk of hand injuries to workers. Therefore, there is an urgent need for a cutting device that can automate the cutting process and improve both accuracy and efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a plate cutting machine that can automatically cut printing PS plates to replace manual labor and improve work efficiency and accuracy.

[0005] The objective of this utility model can be achieved through the following technical solution: A PS plate cutting machine, characterized in that the cutting machine includes a frame, an operating table fixed at the top of the frame, and a plate-laying area in the middle of the operating table; mounting grooves are provided on both sides of the plate-laying area on the upper surface of the operating table, and a steel ruler is fixed in each mounting groove; a first sliding rod is fixed on the outer side of each mounting groove on the upper surface of the operating table, a first slider is slidably connected to each first sliding rod, a push plate is fixed between two first sliders, and a handle is fixed on the top of the push plate; a controller is fixed at the front end of the operating table, and a fixed cutter is detachably connected to the rear end of the operating table; a second sliding rod is fixed on the upper surface of the operating table near the fixed cutter, and the shaft of the second sliding rod... The line is parallel to the axis of the fixed cutter; a second slider is slidably connected to the second slide rod, and a rotating cutter is rotatably connected to the second slider, and the cooperation between the rotating cutter and the fixed cutter can cut the PS plate; a mounting frame is also fixed on the upper surface of the operating table, and several cylinders are vertically fixed on the mounting frame; a pressure plate is provided below the mounting frame, and the push rods of each cylinder are detachably connected to the pressure plate, and the pressure plate can move up and down under the common drive of each cylinder; a pair of pulleys are rotatably connected to the mounting frame, and a rack and pinion belt meshes between the two pulleys; a servo motor is provided on the mounting frame, and the servo motor can drive one of the pulleys to rotate; the second slider is fixedly connected to the rack and pinion belt, and a waste frame is provided below the fixed cutter.

[0006] Preferably, the upper surface of the plate-laying area and the lower surface of the pressure plate are both fixed with anti-scratching plates, which are made of polytetrafluoroethylene material.

[0007] Preferably, a pressure plate roller is rotatably connected to the second slider, and the tire of the pressure plate roller is made of soft plastic material.

[0008] The advantages of this utility model are:

[0009] 1. When cutting PS plates, the operator can use the steel rulers on both sides of the plate placement area to position the plate, then use the pressure plate to fix it, and finally use the servo motor to drive the rotating cutter to cut it. This replaces the manual cutting of PS plates, improves production efficiency, and can effectively avoid the movement and warping of PS plates, thus improving the accuracy of the operation.

A rotating cutter 52 is rotatably connected to the second slider 51, and the cooperation between the rotating cutter 52 and the fixed cutter 4 can realize the cutting of the PS plate. A mounting frame 6 is also fixed on the upper surface of the operating table 2. A cylinder 61 is vertically fixed on the mounting frame 6. A pressure plate 62 is provided below the mounting frame 6. The push rods of each cylinder 61 are detachably connected to the pressure plate 62, and the pressure plate 62 can move up and down under the common drive of each cylinder 61. A pair of pulleys 63 are rotatably connected to the mounting frame 6, and a rack and pinion belt 64 meshes between the two pulleys 63. A servo motor 65 is provided on the mounting frame 6, and the servo motor 65 can drive one of the pulleys 63 to rotate. The second slider 51 is fixedly connected to the rack and pinion belt 64, and a waste box 7 is provided below the fixed cutter 4.

[0017] Working principle:

[0018] 1. Before starting the cutting process, turn on the electrical / pneumatic control switch via controller 3 to power on and supply air. The speed controller can be adjusted according to the cutting speed requirements.

[0019] 2. Place the PS plate to be cut on the work platform. According to the size of the PS plate required by the printing press to be produced, refer to the steel rulers 22 on both sides, and push the PS plate forward through the push plate 25 to achieve precise positioning of the PS plate.

[0020] After the PS plate is positioned, the controller 3 starts each cylinder 61, and each cylinder 61 drives the pressure plate 62 to move down until the PS plate is pressed and fixed to prevent the PS plate from warping, tilting and shifting during cutting.

[0021] 4. The servo motor 65 is started by the controller 3, which drives the second slider 51 to slide on the slide rod through the rack and pinion belt 64, thereby driving the rotating cutter 52 to roll along the top of the fixed cutter 4 to realize the cutting operation of the PS plate. The cut waste material automatically falls into the waste box 7, and the pressure plate 62 and slider automatically move back to the cutting origin.

[0022] When cutting PS plates, the operator can use the steel rulers 22 on both sides of the plate placement area 21 to position the plate, then use the pressure plate 62 to fix it, and finally use the servo motor 65 to drive the rotating cutter 52 to cut it. This replaces manual cutting of PS plates, improves production efficiency, and effectively avoids movement and warping of PS plates, thus improving the accuracy of operation.
