Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1-4 shown, a pneumatic special engineering plastic material slitting device that is easy to adjust includes: a slitting table 1, a support frame 2 fixedly connected to the top of the slitting table 1, cylinders 5 fixedly connected to both sides of the top of the support frame 2, a movable rod 3 fixedly connected to the bottom end of the cylinder 5, blades 4 arranged in equal columns and slidably connected to the inner wall of the movable rod 3, and an adjustment mechanism 6 arranged on the surface of the support frame 2; wherein, the adjustment mechanism 6 includes an air pump 61 fixedly connected to the top of the support frame 2, a corrugated hose 62 communicated with the surface of the air pump 61, a plurality of adjustment cylinders 63 fixedly connected to the inner wall of the movable rod 3, the bottom end of the corrugated hose 62 is communicated with the inner wall of the adjustment cylinder 63, an adjustment rod 64 slidably connected to the inner wall of the adjustment cylinder 63, one end of the adjustment rod 64 is fixedly connected to one end of the blade 4, and an adjustment component 65 is arranged on the surface of the support frame 2. The adjustment component 65 includes a scale 651 fixedly connected to the front end of the support frame 2, a limit frame 652 arranged at the front end of the support frame 2, an indicating block 653 fixedly connected to the bottom of the limit frame 652, and the bottom of the indicating block 653 is in an isosceles triangle shape.

[0025] A pay-off reel is fixedly connected to the top of the slitting table 1. An aggregate roller is rotatably connected to the inner wall of the pay-off reel. A servo motor is fixedly connected to one side of the pay-off reel. The output shaft of the servo motor is fixedly connected to one end of the aggregate roller. A plurality of limiting rollers are rotatably connected to the top of the slitting table 1. A supporting roller is fixedly connected to the inner wall of the support frame 2.

[0026] An air pump 61 is a device for exhausting air from or adding air to a closed space.

[0027] It should be noted that in the above description, the servo motor, the cylinder 5, the air pump 61, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the servo motor, the cylinder 5, and the air pump 61 can be supplied by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0028] When it is necessary to slit special engineering plastic materials, manually turn on the servo motor. The output shaft of the servo motor rotates to drive the aggregate roller to rotate. The aggregate roller rotates to unwind the special engineering plastic materials, so that the special engineering plastic materials pass through the limiting rollers and are placed on the supporting roller. Manually turn on the cylinder 5. The lower end of the cylinder 5 moves downward to drive the movable rod 3 and the blade 4 to move downward, so that the blade 4 touches the special engineering plastic materials. Manually turn off the cylinder 5. At this time, the front end of the slitting table 1 pulls the special engineering plastic materials, so that the special engineering plastic materials move on the supporting roller. The blade 4 slits the moving special engineering plastic materials. When it is not necessary to slit the special engineering plastic materials, manually turn off the servo motor.

[0029] When it is necessary to adjust the spacing between multiple blades 4, push the limit frame 652. After the indicating block 653 moves to a suitable position on the scale 651, manually turn on the air pump 61. The air pump 61 extracts external gas and transports it to each adjusting cylinder 63 through the corrugated hose 62. Excessive gas in the adjusting cylinder 63 pushes the adjusting rod 64 to move. The movement of the adjusting rod 64 drives the blade 4 to move. When the blade 4 touches the limit frame 652, manually turn off the air pump 61, so that multiple blades 4 reach a suitable spacing.

[0030] As Figure 3 shown, a support rod 654 is fixedly connected to the front end of the support frame 2. The inner wall of the limit frame 652 is slidably connected to the surface of the support rod 654. A bolt 655 is threadedly connected to the inner wall of the limit frame 652. The bottom end of the bolt 655 touches the surface of the support rod 654. Rotate the bolt 655. The bolt 655 moves downward in the limit frame 652 and touches the support rod 654, so that the limit frame 652 is locked on the support rod 654, ensuring the limiting effect of the limit frame 652 on the blade 4.

[0031] As Figure 3As shown, one end of the adjusting rod 64 is fixedly connected to a spring 656, the other end of the spring 656 is fixedly connected to one end of the inner wall of the adjusting cylinder 63, and a retaining ring 658 is fixedly connected to the inner wall of the adjusting cylinder 63.

[0032] When the gas in the adjusting cylinder 63 decreases, the elastic force of the spring 656 pushes the adjusting rod 64 towards the retaining ring 658, and the retaining ring 658 limits the moving adjusting rod 64 to prevent the end of the adjusting rod 64 facing the spring 656 from moving to the air outlet of the corrugated hose 62.

[0033] As Figure 3 shown, a series of equally distributed fixing frames 657 are fixedly connected to the upper surface of the movable rod 3, and the surface of the corrugated hose 62 is fixedly connected to the inner wall of the fixing frame 657. The fixing frame 657 is used to support and limit the corrugated hose 62.

[0034] When the present utility model is in use, push the limiting frame 652 to move the indicating block 653 to a suitable position on the scale 651, then rotate the bolt 655. The bolt 655 moves downward in the limiting frame 652 and abuts against the support rod 654, so that the limiting frame 652 is locked on the support rod 654. Manually turn on the air pump 61, and the air pump 61 extracts external gas and transports it to each adjusting cylinder 63 through the corrugated hose 62. When the gas in the adjusting cylinder 63 is excessive, it pushes the adjusting rod 64 to move. The movement of the adjusting rod 64 drives the blade 4 to move. When the blade 4 abuts against the limiting frame 652, manually turn off the air pump 61, so that the multiple blades 4 reach a suitable spacing.

[0035] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
