Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-5 The present invention provides a technical solution to achieve this: a printing press cutting device, including a cutting machine 1, a cutting table 2, a control panel 3, a cutting groove 4, a pressing groove 5, a positioning mechanism 6, and a cutting mechanism 7. The cutting table 2 is located at the front end of the cutting machine 1, the control panel 3 is located at the front end of the cutting machine 1 and at the left end of the cutting table 2, the cutting groove 4 is located inside the cutting table 2, the positioning mechanism 6 and the cutting mechanism 7 are arranged in an upper and lower structure inside the cutting table 2, and the pressing groove 5 is located at the bottom of the cutting mechanism 7.
[0021] The core positioning mechanism 6 includes a clamping plate 61, a positioning groove 62, a rod groove 63, a bidirectional lead screw 64, a motor 65, a slide cylinder 66, a sliding plate 67, a clamping groove 68, and a powerful positive magnetic plate 69. The positioning groove 62 is located inside the clamping plate 61, the rod groove 63 is located inside the clamping plate 61 and above the positioning groove 62, the bidirectional lead screw 64 is located inside the rod groove 63, the motor 65 is located at the right end of the bidirectional lead screw 64 and at the right end of the clamping plate 61, the slide cylinders 66 are arranged opposite each other on the bidirectional lead screw 64, the sliding plate 67 is located at the bottom of each slide cylinder 66, the clamping groove 68 is located at the bottom of the sliding plate 67, and the powerful positive magnetic plate 69 is arranged opposite each other at the front and rear ends of the clamping groove 68. The positioning groove 62 can firmly fix the cutting mechanism 7 inside.
[0022] Specifically, the length of the positioning groove 62 is less than the length of the clamping plate 61, the slide plate 67 has a cuboid structure, and the slide cylinder 66 and the slide plate 67 are integrally formed.
[0023] The cutting mechanism 7 includes a cutting blade 71, a gradient plate 72, a strong negative magnetic plate 73, a common negative magnetic plate 74, and a top plate 75. The cutting blade 71 is located inside the positioning groove 62 and simultaneously inside the clamping groove 68. The gradient plates 72 are arranged opposite each other on top of the cutting blade 71. The strong negative magnetic plate 73 is located at the front and rear ends of each gradient plate 72. The common negative magnetic plate 74 is located next to the strong negative magnetic plate 73. The top plate 75 is located at the outward end of each gradient plate 72. The sliding plate 67 is controlled to slide on the gradient plate 72 by a bidirectional lead screw 64. The clamping plate 61 clamps and fixes the cutting blade 71 or quickly releases it by gradually increasing or decreasing the magnetic attraction force, which greatly improves the efficiency of assembly and disassembly, saving time and effort.
[0024] The outer half of the gradient plate 72 has a cuboid structure, the inner half of the gradient plate 72 has a triangular structure, the strong negative magnetic plate 73 is located in the outer half of the gradient plate 72, the ordinary negative magnetic plate 74 is located in the inner half of the gradient plate 72, the top plate 75 has a cuboid structure, and the cutting blade 71, the gradient plate 72 and the top plate 75 are integrally formed.
[0025] The portion between the top of each top plate 75 and the bottom of the rod groove 63 is the clamping plate 61. This area is the main force application area of the clamping plate 61 on the cutting mechanism 7. It does not affect the movement of the slide plate 67 on the gradient plate 72, but the movement distance is limited by the opposite sides of the two top plates 75. There is no obstruction between the two opposite top plates 75, and there is a small gap between the two gradient plates 72.
[0026] Working principle: When the cutting mechanism 7 needs to be disassembled, first place the existing support for the cutting mechanism 7 at the bottom of the cutting mechanism 7. Then, control the clamping plate 61 to move the cutting mechanism 7 to be close to the support. Then, start the motor 65 to drive the bidirectional lead screw 64 to rotate, thereby causing the two slide plates 67 to move from the outside to the inside on the gradient plate 72. During the displacement, the strong positive magnetic plate 69 will pass through the strong negative magnetic plate 73 and the ordinary negative magnetic plate 74 in sequence. Therefore, the magnetic attraction force on the strong positive magnetic plate 69 gradually decreases until it can no longer support the weight of the cutting mechanism 7. At this time, the clamping plate 61 can be lifted and the support removed for replacement. During operation, the mutual attraction between the strong positive magnetic plate 69 and the strong negative magnetic plate 73 can work with the positioning groove 62 to firmly fix the cutting mechanism 7. At the same time, each cut further strengthens the stability of the cutting mechanism 7.
