Description

Technical Field

[0001] The present invention relates to the technical field of crawler production, in particular to a rubber crawler steel wire rubber coating process and device. Background Art

[0002] A rubber crawler is an annular rubber belt composed of a composite of rubber, metal, and fiber materials, and is mainly applicable to the running parts of agricultural machinery, construction machinery, and transportation vehicles. Rubber crawlers have excellent properties such as small ground contact pressure, large traction force, low noise, good passing performance in wet fields, no damage to the road surface, high speed, and light mechanical weight, and are widely used in agricultural machinery, construction machinery, and transportation machinery, partially replacing steel crawlers and tires. When producing rubber crawlers, rubber coating of steel wires is an essential step. When producing rubber crawlers, rubber coating of steel wires can be carried out on single steel wires or on cord composed of multiple steel wires. Therefore, when rubber coating steel wires of rubber crawlers, steel wire rubber coating equipment is required.

[0003] Currently, when coating steel wires with rubber, air bubbles are easily wrapped in the rubber compound, and it is inconvenient to deal with the air bubbles, resulting in the air bubbles being wrapped on the surface of the steel wires along with the rubber compound. As the steel wires move, the rubber coating on the surface of the steel wires is not uniform enough, affecting the rubber coating effect of the rubber crawler steel wires. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] A rubber crawler steel wire rubber coating process, comprising the following steps:

[0006] Step 1: Steel wire preparation: Select appropriate steel wires by selecting high-strength and corrosion-resistant steel wires;

[0007] Step 2: Rubber compound preparation: Add a promoter and an adhesive to the raw materials of the rubber compound, and stir the materials to make a mixed rubber compound. The promoter can accelerate the speed of the vulcanization reaction, reduce the vulcanization temperature, shorten the vulcanization time, and at the same time can also improve the crosslinking density and physical properties of the vulcanized rubber, reducing the dosage of the vulcanizing agent;

[0008] The adhesive can improve the adhesion strength between the rubber and the steel wire, ensure that the steel wire can be firmly fixed in the rubber, prevent the phenomenon of the steel wire from peeling off from the rubber during use, and thus ensure the overall performance of the rubber crawler.

[0009] Step 3: Steel wire treatment: Perform surface pretreatment on the steel wires in Step 1;

[0010] Step 4: Steel wire rubber coating: Coat the mixed rubber compound in Step 2 on the steel wires by extrusion;

[0011] Step 5: Vulcanization treatment: Put the rubber-coated steel wires into a vulcanization device for vulcanization treatment;

[0012] Step Six: Post-processing: Trim the edges of the vulcanized rubber track steel wire, remove the flash, and clean the surface.

[0038] 8. The rubber track wire rubber coating process and device uses a toggling blade to apply a driving force to the stressed teeth, and under the sliding connection of the connecting slider, the conical cover moves to the side away from the toggling blade, and the spring is compressed. As the toggling blade separates from the stressed teeth, the driving force on the stressed teeth disappears, and under the elastic force of the spring, the connecting slider drives the conical cover to move in the opposite direction for reset. In this way, the conical cover drives the elastic brush to move back and forth, so that the surface of the steel wire can be brushed back and forth. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] Second Embodiment, on the basis of the first embodiment, please refer to Figures 1 to 8 as shown:

[0061] The rubber track wire coating device includes:

[0062] The machine body 1, and the machine head 2 fixedly installed at the top side of the machine body 1. A feeding mechanism 3 is installed at the top side of the machine body 1;

[0063] The feeding mechanism 3 includes a support frame 31 and a driving roller 32. The bottom of the support frame 31 is fixedly installed at the top side of the machine body 1. The driving roller 32 is rotatably installed on the top of the support frame 31. A driver 33 is installed at the side of the surface of the support frame 31. A driven roller 34 is rotatably installed in the middle of the inner side of the support frame 31. Anti-slip strips 35 are fixedly connected to the outer circumferential surfaces of the driving roller 32 and the driven roller 34. At both ends of the outer circumferential surface of the driving roller 32, stirring blades 36 are fixedly connected. When the staff starts the driver 33 to work, by the rotation of the output end of the driver 33, the driving roller 32 can be driven to rotate, and with the rolling support of the driven roller 34, the wire located between the driving roller 32 and the driven roller 34 can be conveyed. The driving roller 32 and the driven roller 34 are in two groups, and the two groups of driving rollers 32 and driven rollers 34 are distributed at both ends of the top of the support frame 31 to convey the wire for feeding at a constant speed;

[0064] The driven roller 34 is installed directly below the driving roller 32. The driver 33 and the driving roller 32 are installed at the same height, and the driving roller 32 and the output end of the driver 33 are fixedly installed through a coupling. The anti-slip strips 35 are evenly distributed on the outer circumferential surfaces of the driving roller 32 and the driven roller 34, and as the driving roller 32 and the driven roller 34 rotate, the anti-slip strips 35 are driven to rotate together, so that the anti-slip strips 35 contact the wire, and it is not easy for the wire to slip.

[0065] The anti-slip strips 35 are evenly distributed on the outer circumferential surfaces of the driving roller 32 and the driven roller 34. The material of the anti-slip strips 35 is rubber, and the stirring blades 36 are arc-shaped.

[0066] The processing mechanism 4 is used for coating the rubber track wire, and the processing mechanism 4 is installed between the top of the machine head 2 and the top of the machine body 1;

[0067] Among them, the processing mechanism 4 includes a feeding main machine 41 and a rubber coating cylinder 42. The feeding main machine 41 is installed on the side of the top of the machine head 2, and the rubber coating cylinder 42 is fixedly connected to the side of the top of the machine body 1 through support legs. The rubber coating cylinder 42 is communicated with the feeding main machine 41. At both ends of the top of the rubber coating cylinder 42, a wire inlet hopper 43 and a wire outlet hopper 44 are sequentially installed. On both sides of the inner cavity of the rubber coating cylinder 42, guiding rollers 45 are rotatably installed. In the middle of the inner cavity of the rubber coating cylinder 42, an elastic scraper 46 is fixedly connected. At the support leg at the bottom of the rubber coating cylinder 42, a vibration assembly 47 is installed. As the driving roller 32 and the driven roller 34 rotate to convey the steel wire, the steel wire enters the inside of the rubber coating cylinder 42 from the wire inlet hopper 43, and the feeding main machine 41 supplies rubber material to the inside of the rubber coating cylinder 42, so that the steel wire entering the rubber coating cylinder 42 can contact the rubber material, and the steel wire can be rubber-coated. And through the guiding of the guiding rollers 45, and as the steel wire moves, the guiding rollers 45 roll. By using rolling friction, the friction force is reduced, which helps the steel wire to move smoothly, and the steel wire is led out from the wire outlet hopper 44, so that the steel wire presents a bent shape after entering the rubber coating cylinder 42, increasing the contact area between the steel wire and the rubber material inside the rubber coating cylinder 42, and promoting the rubber coating of the steel wire.

[0068] The rubber coating cylinder 42 is installed directly below the feeding main machine 41. The wire inlet hopper 43 and the wire outlet hopper 44 are installed at the same height. The elastic scrapers 46 are evenly distributed in the middle of the inner cavity of the rubber coating cylinder 42.

[0069] As the steel wire keeps moving, and combined with the fact that the end of the elastic scraper 46 far away from the inner wall of the rubber coating cylinder 42 fits the surface of the steel wire, the rubber material attached to the surface of the steel wire can be scraped, and the air bubbles wrapped by the rubber material can be scraped and broken. The air bubbles burst in time, and the rubber coating on the surface of the steel wire is uniform.

[0070] The vibration assembly 47 includes a V-shaped swing rod 471 and a reset elastic strip 472. The V-shaped swing rod 471 is hinged on the surface of the supporting leg at the bottom of the rubber coating cylinder 42. The reset elastic strip 472 is fixedly connected between the surface of the V-shaped swing rod 471 and the conical surface of the rubber coating cylinder 42. One end of the V-shaped swing rod 471 is fixedly connected to a U-shaped force rod 473, and the U-shaped force rod 473 and the toggling blade 36 are installed at the same height. The end of the V-shaped swing rod 471 away from the U-shaped force rod 473 is fixedly connected to a knocking rod 474, which drives the toggling blade 36 to rotate through the active roller 32. The toggling blade 36 applies an upward toggling force to the top of the U-shaped force rod 473 and Under the rotation connection of 71, the V-shaped swing rod 471 drives the knocking rod 474 to rotate clockwise, and the reset elastic strip 472 is compressed, and the toggling blade 36 is used to disengage from the U-shaped force-bearing rod 473, and the toggling force on the top of the U-shaped force-bearing rod 473 disappears, and under the elastic force of the reset elastic strip 472, the V-shaped swing rod 471 drives the knocking rod 474 to rotate counterclockwise for reset, so that the knocking rod 474 knocks the bottom of the rubber coating tube 42, thereby vibrating the rubber material in the rubber coating tube 42, and the bubbles suspended in the rubber material can be floated upward, reducing the contact between the bubbles and the steel wire, and under the action of vibration, the rubber material itself is solidified and fully contacts the steel wire.

[0071] There are two V-shaped swing rods 471 , and the two V-shaped swing rods 471 are symmetrically installed along the central axis of the middle of the rubber coating cylinder 42 , and the top end of the U-shaped force-bearing rod 473 is arc-shaped.

[0072] The third embodiment, based on the first and second embodiments, see Figures 1 to 10 As shown:

[0073] A pretreatment mechanism 5 is installed on the side of the top of the machine head 2. The pretreatment mechanism 5 includes a rectangular guide rail 51, which is fixedly connected to the side of the top of the machine head 2 by screws, and the rectangular guide rail 51 is installed directly above the support frame 31. A connecting slider 52 is slidably installed inside the rectangular guide rail 51, and the bottom end of the connecting slider 52 is fixedly connected to a conical cover 53, and the inner side of the conical cover 53 is fixedly connected to an elastic brush 54. A force-bearing tooth 55 is fixedly connected to the conical surface of the conical cover 53. The force-bearing tooth 55 and the shifting blade 36 are installed at the same height. A spring 56 is fixedly connected between the surface of the connecting slider 52 and the inner wall of the rectangular guide rail 51. A steel wire is passed through the center of the conical cover 53, and the end of the elastic brush 54 away from the inner wall of the conical cover 53 contacts the surface of the steel wire to brush the surface of the steel wire and clean up the debris attached to the surface of the steel wire.

[0074] The top of the connecting slider 52 is fitted with the inner side surface of the rectangular guide rail 51 . The connecting slider 52 is installed directly below the rectangular guide rail 51 , and the conical cover 53 is installed directly below the connecting slider 52 .

[0075] As the driving roller 32 drives the dialing blade 36 to continuously rotate, the end of the dialing blade 36 can be used to contact the stress tooth 55, so that the stress tooth 55 receives the driving force of the dialing blade 36. Under the sliding connection of the connecting slider 52, the conical cover 53 moves away from the dialing blade 36, and the spring 56 is compressed. Along with the separation of the dialing blade 36 from the stress tooth 55, the driving force received by the stress tooth 55 disappears. Under the elastic force of the spring 56, the connecting slider 52 drives the conical cover 53 to move in the reverse direction for reset. In this way, the conical cover 53 drives the elastic brush 54 to move reciprocally to brush the surface of the steel wire reciprocally.

[0076] The stress tooth 55 is arc-shaped. There are two stress teeth 55, and the two stress teeth 55 are symmetrically installed along the central axis of the conical cover 53. The elastic brushes 54 are evenly distributed on the inner side surface of the conical cover 53.

[0077] During use, first pass the steel wire to be coated with glue through between the driving roller 32 and the driven roller 34, and pass through the center of the conical cover 53, and use the feeding main machine 41 to inject the glue into the inside of the coating cylinder 42;

[0078] At this time, the staff starts the driver 33 to work. By using the rotation of the output end of the driver 33, the driving roller 32 can be driven to rotate. Under the rolling support of the driven roller 34, the steel wire between the driving roller 32 and the driven roller 34 can be conveyed. Considering that the driving roller 32 and the driven roller 34 are in two groups, and the two groups of driving rollers 32 and driven rollers 34 are distributed at both ends of the top of the support frame 31, the steel wire is fed at a uniform speed;

[0079] And the anti-slip strips 35 are evenly distributed on the outer circumferential surfaces of the driving roller 32 and the driven roller 34. As the driving roller 32 and the driven roller 34 rotate, the anti-slip strips 35 are driven to rotate together, so that the anti-slip strips 35 contact the steel wire, and it is not easy for the steel wire to slip;

[0080] And by passing the steel wire through the center of the conical cover 53, and combining the end of the elastic brush 54 away from the inner wall of the conical cover 53 to contact the surface of the steel wire, the surface of the steel wire is brushed to clean the sundries attached to the surface of the steel wire;

[0081] As the driving roller 32 drives the stirring blades 36 to continuously rotate, the end of the stirring blade 36 can be used to contact the stressed teeth 55, so that the stressed teeth 55 are pushed by the stirring blade 36. Under the sliding connection of the connecting slider 52, the conical cover 53 moves away from the stirring blade 36, and the spring 56 is compressed. Along with the separation of the stirring blade 36 from the stressed teeth 55, the pushing force on the stressed teeth 55 disappears. Under the elastic force of the spring 56, the connecting slider 52 drives the conical cover 53 to move in the reverse direction for resetting. In this way, the conical cover 53 drives the elastic brush 54 to reciprocate, and the surface of the steel wire is brushed reciprocally;

[0082] Moreover, as the driving roller 32 and the driven roller 34 rotate to convey the steel wire, the steel wire enters the inside of the rubber coating cylinder 42 from the wire inlet hopper 43, and the feeding main machine 41 supplies rubber material to the inside of the rubber coating cylinder 42. Then the steel wire entering the rubber coating cylinder 42 can contact the rubber material, so that the steel wire can be rubber-coated. And through the guiding of the guiding roller 45, along with the movement of the steel wire, the guiding roller 45 rolls. By using rolling friction, the friction force is reduced, which helps the steel wire to move smoothly. Then the steel wire is led out from the wire outlet hopper 44, making the steel wire show a bent shape after entering the rubber coating cylinder 42, increasing the contact area between the steel wire and the rubber material inside the rubber coating cylinder 42, and promoting the rubber coating of the steel wire;

[0083] As the steel wire keeps moving, and combined with the end of the elastic scraping strip 46 away from the inner wall of the rubber coating cylinder 42 fitting with the surface of the steel wire, the rubber material attached to the surface of the steel wire can be scraped, and the air bubbles wrapped by the rubber material can be scraped and broken. The air bubbles break in time, and the rubber coating on the surface of the steel wire is uniform;

[0084] At the same time, the driving roller 32 drives the stirring blade 36 to rotate. The stirring blade 36 exerts an upward pushing force on the top of the U-shaped stressed rod 473. Under the rotational connection of the V-shaped swing rod 471, the V-shaped swing rod 471 drives the knocking rod 474 to rotate clockwise, and the reset elastic strip 472 is compressed. By using the separation of the stirring blade 36 from the U-shaped stressed rod 473, the pushing force on the top of the U-shaped stressed rod 473 disappears. Under the elastic force of the reset elastic strip 472, the V-shaped swing rod 471 drives the knocking rod 474 to rotate counterclockwise for resetting, so that the knocking rod 474 knocks on the bottom of the rubber coating cylinder 42, thereby vibrating the rubber material in the rubber coating cylinder 42. Then the air bubbles suspended in the rubber material can float upward, reducing the contact between the air bubbles and the steel wire. Under the action of vibration, the rubber material itself is settled, and the rubber material fully contacts the steel wire;

[0085] As the steel wire moves out from the wire outlet hopper 44, the steel wire can be pulled by an external traction mechanism, and then the steel wire can be subjected to the rubber coating processing for the outgoing wire.
