Description

Technical Field

[0001] This utility model belongs to the field of aramid processing technology, specifically relating to an aramid conveyor belt one-time calendering forming device. Background Technology

[0002] Aramid, also known as aromatic nylon, is a new type of high-tech synthetic fiber. Aramid has a relative density of 1.33–1.36, is insoluble in water, methanol (ethanol), acetone, gasoline, etc., but soluble in concentrated sulfuric acid. It possesses excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, light weight, insulation, aging resistance, and long lifespan, and is widely used in composite materials, bulletproof products, building materials, special protective clothing, electronic equipment, and other fields.

[0003] Existing calendering equipment is inconvenient for timely stretching of aramid fibers. The strip is prone to shrinkage and deformation at high temperatures, affecting dimensional accuracy. Furthermore, the fixed gap between the calendering rolls cannot be adapted to materials of different thicknesses, resulting in poor adhesion between the adhesive web and the aramid web, which easily leads to delamination during use. In addition, it relies on manual operation, resulting in low production efficiency and large quality fluctuations. In particular, aramid materials have poor dynamic fatigue resistance, and traditional processes will exacerbate their interface aging problems. Utility Model Content

[0017] 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.

[0018] Example Please see Figure 1-4 The technical solution provided in this embodiment is as follows: A one-time calendering device for aramid conveyor belts includes: a support base 1, a conveying mechanism 2 fixedly connected to the upper surface of the support base 1, a calendering mechanism 3 fixedly connected to one side of the conveying mechanism 2, and a stretching mechanism 4 fixedly connected to one side of the calendering mechanism 3. The conveying mechanism 2 includes a conveying frame 201 fixedly connected to the upper surface of the support base 1, and multiple first sliding seats 203 slidably connected to both sides of the conveying frame 201. A conveying roller 204 is rotatably connected inside the first sliding seat 203. The calendering mechanism 3 includes a calendering frame 301 fixedly connected to the upper surface of the support base 1, and a first sliding seat 204 is rotatably connected inside the calendering frame 301. The calendering roller 302 and the calendering frame 301 are slidably connected to a second sliding seat 304. The second sliding seat 304 is rotatably connected to a second calendering roller 305. With the support seat 1 as the basic frame, the conveying mechanism 2 is responsible for orderly conveying the aramid web and the rubber web to the calendering mechanism 3. The aramid web and the rubber web are pulled into the calendering area by the rolling traction of the conveying roller 204. The first calendering roller 302 and the second calendering roller 305 roll and combine the materials in the calendering frame 301 to form a preliminary strip blank. Subsequently, the stretching mechanism 4 uses the first stretching roller 402 and the second stretching roller 405 to control the tension of the strip blank to prevent deformation.

[0019] Specifically, multiple first electric cylinders 205 with crisscrossing openings are fixedly connected to the surfaces on both sides of the conveyor frame 201, and the piston rods of the multiple first electric cylinders 205 are fixedly connected to the first sliding seat 203 respectively.

[0020] In a specific embodiment of this utility model, the first electric cylinder 205 pushes the first sliding seat 203 to move vertically on the conveyor frame 201 through the piston rod, thereby adjusting the height of the conveyor roller 204. This adjustment can adjust the conveying angle and tension in real time according to the thickness of the aramid mesh and the rubber mesh, ensuring that the material enters the calendering area flat. The precise control of the first electric cylinder 205 avoids the error of manual adjustment and improves the stability of the conveying. The cross-opening design enhances the rigidity of the structure, prevents the first sliding seat 203 from shifting, and effectively reduces the phenomenon of material slippage or wrinkling.

[0021] Specifically, the surface of the conveyor frame 201 is fixedly connected to two mounting seats 206, and the inside of the mounting seats 206 is rotatably connected to the feed roller 202.

[0022] In a specific embodiment of this utility model, the feed roller 202 is fixed on the conveyor frame 201 by the mounting base 206. The rolling action of the feed roller 202 guides the aramid web and the rubber web for conveying. The rotatable design of the mounting base 206 allows the feed roller 202 to adapt to the material curling angle and reduce the feeding resistance.

[0023] Specifically, a first servo motor 303 for driving the first calender roll 302 is fixedly connected to the surface of the calender frame 301, and a second servo motor 306 for driving the second calender roll 305 is fixedly connected to the surface of the second sliding seat 304.

[0024] In a specific embodiment of this utility model, the first servo motor 303 and the second servo motor 306 drive the first calendering roll 302 and the second calendering roll 305 to rotate respectively, and the servo system can precisely control the speed and torque of the rolls.

[0025] Specifically, a connecting seat 307 is fixedly connected to the top of the second sliding seat 304, and two spring telescopic rods 308 are fixedly connected to the upper surface of the connecting seat 307. A connecting plate 310 is fixedly connected to the top of the spring telescopic rods 308.

[0026] In a specific embodiment of this utility model, the spring telescopic rod 308 connects the second sliding seat 304 and the connecting plate 310, providing elastic buffering during the calendering process. When the material thickness changes, the spring telescopic rod 308 automatically compensates for the pressure, avoiding overpressure damage to the aramid fibers.

[0027] Specifically, the top of the calender 301 is fixedly connected to two support frames 309, and the surface of the support frame 309 is fixedly connected to a second electric cylinder 311 with the opening facing it. The piston rod of the second electric cylinder 311 is fixedly connected to the connecting plate 310.

[0028] In a specific embodiment of this utility model, the piston rod of the second electric cylinder 311 pushes the connecting plate 310, and then adjusts the gap of the second calendering roller 305 through the spring telescopic rod 308. The support frame 309 fixes the position of the second electric cylinder 311 to ensure that the thrust acts perpendicularly on the first calendering roller 302 and the second calendering roller 305.

[0029] Specifically, the stretching mechanism 4 includes a stretching frame 401 fixedly connected to the upper surface of the support base 1, a first stretching roller 402 rotatably connected to the stretching frame 401, a horizontally extending guide groove 403 opened on the surface of the stretching frame 401, a third sliding seat 404 slidably connected to the surface of the guide groove 403, and a second stretching roller 405 rotatably connected inside the third sliding seat 404.

[0030] In a specific embodiment of this utility model, the first stretching roller 402 and the second stretching roller 405 on the stretching frame 401 work together. The second stretching roller 405 moves horizontally in the guide groove 403 through the third sliding seat 404 to adjust the tension of the strip blank. During the stretching process, the strip blank is cooled and shaped to avoid shrinkage.

[0031] A third electric cylinder 406 is fixedly connected to one side of the tensioning frame 401, and the piston rod of the third electric cylinder 406 is fixedly connected to the guide groove 403.

[0032] In a specific embodiment of this utility model, the third electric cylinder 406 pushes the third sliding seat 404 in the guide groove 403 to control the horizontal displacement of the second stretching roller 405. By adjusting the stroke of the third electric cylinder 406, the stretching ratio can be changed in real time to adapt to different specifications of strip blanks.

[0033] Working principle: The process begins with the aramid web and rubber web being guided into the conveying mechanism 2 by the feed roller 202. The conveying mechanism 2 adjusts the height of the conveying roller 204 through the first electric cylinder 205 to ensure that the material enters the calendering area with constant tension. The calendering mechanism 3 is the core part. The first calendering roller 302 and the second calendering roller 305 rotate in opposite directions under the drive of the servo motor to roll and composite the aramid web and rubber web. At this time, the second electric cylinder 311 dynamically adjusts the calendering gap through the spring telescopic rod 308 to avoid over-pressure or insufficient pressure. During the calendering process, the thermal action of the first stretching roller 402 and the second stretching roller 405 causes the rubber and aramid fibers to penetrate and bond, forming a uniform strip. Subsequently, the strip enters the stretching mechanism 4. The first stretching roller 402 and the second stretching roller 405 apply transverse tension under the control of the third electric cylinder 406, so that the molecular chains of the strip are oriented during the cooling process, enhancing the mechanical properties.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
