Abstract
Description
Technical Field
[0001] The utility model belongs to the field of cutting equipment in a PC / PET corrugated tile production line, in particular to a PC / PET molding shearing device. Background Art
[0002] After PC / PET corrugated tiles are formed in the production line, they usually need to be cut evenly by a shearing device. The existing PC / PET corrugated tile shearing device usually cuts by pressing the cutter horizontally downward. The flat cutting method has a large contact surface, and it is not easy to cut the PC / PET corrugated tiles with low pressure. Excessive pressure can easily damage the product or the cutter itself. Utility Model Content
[0003] The utility model provides a PC / PET molding and shearing device to solve the above technical problems.
[0004] The solution adopted by the utility model to achieve its technical effect is:
[0005] The PC / PET molding and cutting device comprises a workbench, a work frame and a cutting mechanism; the work frame is arranged on the workbench; the cutting mechanism comprises a positioning frame, a first pair of scissors, two lifting cylinders and a second pair of scissors; the positioning frame is arranged on the work frame; the first pair of scissors is arranged on one side of the positioning frame; the two lifting cylinders are symmetrically arranged on the top of the work frame, and the telescopic ends of the two lifting cylinders are symmetrically hinged at the two ends of the top of the second pair of scissors; the second pair of scissors is located directly above the first pair of scissors, and the top of the first pair of scissors and the top of the second pair of scissors are respectively provided with corresponding wave-shaped blades.
[0006] Preferably, a slide rail is provided on the workbench; a slider is provided at the bottom of the work frame; and the slider is slidably sleeved on the outer side of the slide rail.
[0007] Preferably, the first scissors are fixed to one side of the positioning frame by bolts.
[0008] Preferably, the shearing mechanism also includes two guide rails and a mounting plate; the two guide rails are symmetrically arranged on both sides of the working frame; the telescopic ends of the two lifting cylinders are symmetrically hinged at the top two ends of one side of the mounting plate; the two sides of the mounting plate are slidably arranged in the two guide rails; the second scissors are arranged on one side of the mounting plate.
[0009] Preferably, the second scissors are fixed to one side of the mounting plate by bolts.
[0010] Preferably, a return spring is arranged between the top of the working frame and the mounting plate; the return spring is arranged adjacent to one of the lifting cylinders.
[0011] The beneficial effects of the utility model are:
[0012] 1. The top two ends of the second scissors are respectively hinged to the telescopic ends of the two lifting cylinders. Before working, the two lifting cylinders are adjusted to make their telescopic ends extend in different lengths, so that the horizontal heights of the two ends of the second scissors are inconsistent. During working, the telescopic ends of the two lifting cylinders extend synchronously to control the second scissors to descend. Therefore, the lower end of the second scissors will first contact the corresponding end of the first scissors to cut one side of the product first, and then the shorter telescopic end will continue to descend, so that the higher end of the second scissors will gradually press down and be level with the lower end. In the process, it cooperates with the first scissors to form a scissor-like contact to gradually cut the product as a whole. Compared with the existing flat cutting method, scissor-type shearing is easier to cut the product.
[0013] 2. The first scissors and the second scissors are respectively provided with corresponding wave-shaped blades. In actual work, the wave-shaped blades can be matched with the corresponding wave-shaped blades according to the product waveform to cut the wave-shaped tiles. The shearing process will not flatten the raised parts of the wave-shaped tiles, and the product quality is more intact. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. It should be noted that when an element is referred to as "fixed on" or "set on" another element, it can be directly on the other element or there may be a centering element at the same time. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there may be a centering element at the same time. When an element is referred to as being "fixedly connected to" another element, it can be a common fixed connection method such as welding, bolting or gluing.
[0017] Please refer to Figure 1In a preferred embodiment of the utility model, a PC / PET molding and cutting device is disclosed, comprising a workbench 1, a work frame 2 and a cutting mechanism; the work frame 2 is arranged on the workbench 1; the cutting mechanism comprises a positioning frame 3, a first scissors 4, two lifting cylinders 5 and a second scissors 6; the positioning frame 3 is arranged on the work frame 2; the first scissors 4 are arranged on one side of the positioning frame 3; the two lifting cylinders 5 are symmetrically arranged on the top of the work frame 2, and the telescopic ends of the two lifting cylinders 5 are symmetrically hinged at the two ends of the top of the second scissors 6; the second scissors 6 is located directly above the first scissors 4, and the top of the first scissors 4 and the top of the second scissors 6 are respectively provided with corresponding wave-shaped blades 7.
[0018] Specifically, a slide rail 8 is provided on the workbench 1; a slider 9 is provided at the bottom of the work frame 2; and the slider 9 is slidably sleeved on the outer side of the slide rail 8. When shearing products, the work frame 2 moves forward synchronously with the movement of the corrugated tile, so the work frame 2 is additionally equipped with a propulsion mechanism to ensure that the moving speed of the work frame 2 is consistent with the moving speed of the corrugated tile on the production line.
[0019] Specifically, the shearing mechanism also includes two guide rails 10 and a mounting plate 11; the two guide rails 10 are symmetrically arranged on both sides of the working frame 2; the telescopic ends of the two lifting cylinders 5 are symmetrically hinged at the top two ends of one side of the mounting plate 11; the two sides of the mounting plate 11 are slidably arranged in the two guide rails 10; the second scissors 6 are arranged on one side of the mounting plate 11.
[0020] Specifically, the first scissors 4 are fixed to one side of the positioning frame 3 by bolts, and the second scissors 6 are fixed to one side of the mounting plate 11 by bolts. The first scissors 4 and the second scissors 6 are replaceable, so as to match the corresponding wave-shaped blades 7 according to the waveform of the product.
[0021] Specifically, a return spring 12 is provided between the top of the work frame 1 and the mounting plate 11; the return spring 12 is arranged adjacent to one of the lifting cylinders 5. When the second scissors 6 and the first scissors 7 work together to cut the product, the two ends of the mounting plate 11 are at the same level, and after the telescopic ends of the two lifting cylinders 5 are synchronously reset and retracted to the same level, the telescopic end of one of the lifting cylinders 5 continues to retract, and the adjacent return spring 12 cooperates with the telescopic end to pull up one end of the mounting plate 11 through the restoring elastic force to facilitate the next scissor-style shearing.
