Description

Technical Field

[0001] This utility model relates to a tire manufacturing cord calendering machine, belonging to the field of tire manufacturing. Background Technology

[0002] The ply layer forms the skeleton structure of a pneumatic tire, and it is made up of multiple layers of rubber-coated cord material tightly bonded together. This layer mainly bears most of the load on the tire. In conventional tire design, the ply layer is produced using a ply calendering machine.

[0003] Chinese Patent Application No. CN202321169610.5 discloses a tire manufacturing cord calendering machine, including a frame with a pair of frames connected by a contact plate. Each frame has a traction roller frame connected to its inner wall. Traction roller A and traction roller B are rotatably connected between the traction roller frames. A punching assembly is located between traction roller A and traction roller B, rotatably connected to the traction roller frame. Both traction roller A and traction roller B have edge-cutting mechanisms on their outer peripheries. This invention enables the cutting of rubber of different elongation lengths, improving the efficiency and range of the cutting process.

[0004] Given the fixed distance between traction roller A and traction roller B, the current solution cannot meet the production needs of different types of tires. In particular, when the thickness of the cord rubber layer is not uniform, the machine will have difficulty handling the thicker rubber layer. In addition, since the cutting and other adjustment machines in the above solution need to be tightened and loosened multiple times for adjustment, the frequent tightening and loosening adjustments in actual applications are not only time-consuming but also inefficient.

[0024] 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.

[0025] Please see Figures 1-6 As shown, a tire manufacturing cord calender includes a table 1, support feet 4, mounting plate 5, a first traction roller 6, a second traction roller 7, a rotating shaft 8, and a punching needle 9. It also includes a spacing adjustment component 2 and an auxiliary tensioning component 3. The support feet 4 are fixedly installed on the lower part of the table 1, and the mounting plate 5 is fixedly installed on the side of the table 1. The first traction roller 6 is rotatably connected between the mounting plates 5, and the rotating shaft 8 is rotatably connected below the first traction roller 6. The punching needle 9 is fixedly installed on the outer surface of the rotating shaft 8, and the second traction roller 7 is rotatably connected below the rotating shaft 8. The spacing adjustment component 2 is located on the side of the mounting plate 5, and the auxiliary tensioning component 3 is located on the upper part of the table 1. The spacing adjustment component 2 allows users to adjust it according to their needs to adapt to the processing of rubber of various thicknesses.

[0026] like Figures 1-6As shown, the spacing adjustment assembly 2 includes a movable plate 201. A groove is provided on the side wall of the mounting plate 5, and the movable plate 201 moves within the groove. The two ends of a first traction roller 6 are rotatably connected between the movable plates 201. The two ends of a second traction roller 7 are rotatably connected to the lower movable block. A concave frame 202 is fixedly installed on the lower part of the platform 1, and a dual-axis motor is fixedly installed on the upper part of the concave frame 202. A transmission shaft 203 is rotatably connected between the inner and outer walls of the concave frame 202. A main bevel gear 204 is fixedly installed at one end of the transmission shaft 203. A first bidirectional lead screw 206 is rotatably connected between the inner and outer walls of the movable plate 201. A fixed side plate is fixedly installed on the side wall of the mounting plate 5, and a shaft 207 is rotatably connected between the inner and outer walls of the fixed side plate. The upper end of the shaft 207 is connected to... The lower end of the first bidirectional lead screw 206 is fixedly connected, and the lower end of the shaft 207 is fixedly mounted with a secondary bevel gear 205. The secondary bevel gear 205 meshes with the main bevel gear 204. A circular through groove is opened inside the first traction roller 6, and a mounting block 208 is fixedly installed inside the circular through groove. A second bidirectional lead screw 209 is rotatably connected between the mounting blocks 208. A cutter 210 slides on the outer surface of the first traction roller 6. A square groove is opened on the upper part of the first traction roller 6, and a slide rod 212 slides inside the square groove. The top of the slide rod 212 is fixedly connected to the lower part of the cutter 210. A small motor is fixedly installed on the side wall of the fixed side plate. The output end of the small motor passes through the side wall of the fixed side plate and is fixedly connected to one end of the second bidirectional lead screw 209. A movable circular block 211 is screwed onto the outer surface of the double-acting lead screw 209. The lower part of the slide rod 212 is fixedly connected to the outer surface of the movable circular block 211. The first traction roller 6 has heat dissipation holes inside. When processing thicker fabric, the dual-axis motor is turned on. When the dual-axis motor drives the transmission shaft 203 to rotate, the main bevel gear 204 rotates. When the main bevel gear 204 rotates, it drives the secondary bevel gear 205 to rotate. When the secondary bevel gear 205 rotates, it drives the shaft 207 to rotate. When the shaft 207 rotates, it drives the first double-acting lead screw 206 to rotate. When the first double-acting lead screw 206 rotates, it drives the upper and lower movable plates 201 to move away from each other, so that the first traction roller... The increased gap between roller 6 and the first traction roller 6 facilitates the processing of thicker fabric, thus alleviating the problem of the machine struggling to handle thicker adhesive layers when the thickness of the adhesive layer varies. After the gap adjustment is completed, the fabric is passed between the first traction roller 6 and the rotating shaft 8, allowing the punching needle 9 to punch holes in the fabric. Simultaneously, when it is necessary to cut off the extended rubber, the small motor is activated, driving the second bidirectional lead screw 209 to rotate. As the second bidirectional lead screw 209 rotates, it moves the moving circular block 211, which in turn moves the slide bar 212. As the slide bar 212 moves, the cutters 210 at both ends move, allowing them to be adjusted according to the width of the fabric.This allows the extended rubber to be cut off by the cutter 210. The distance between the two cutters 210 can be adjusted in one go via electric adjustment, thus avoiding the problems of frequent tightening and loosening adjustments required by traditional adjustment machines, which are not only time-consuming but also inefficient.

[0027] like Figures 2-4 As shown, the auxiliary tensioning assembly 3 includes a connecting plate 301 fixedly installed on the side wall of the tabletop 1. A rotating plate 302 is provided on the side wall of the connecting plate 301. A driven shaft is rotatably connected between the inner and outer walls of the connecting plate 301. One end of the driven shaft is fixedly connected to the back of the rotating plate 302. A rotating roller 303 is rotatably connected between the rotating plates 302. A stepper motor 304 is fixedly installed on the side wall of the connecting plate 301. The output end of the stepper motor 304 passes through the side wall of the connecting plate 301 and is fixedly connected to one end of the driven shaft. A mounting bracket is fixedly installed on the side wall of the tabletop 1. A cylinder 305 is rotatably connected to the side wall of the mounting bracket. A take-up drum 306 is sleeved on the outside of the cylinder 305. Bolts connect the curtain to the cylinder 305. After the gap width of the curtain is adjusted, the curtain is first passed through the rotating rollers 303 in sequence, then passed through the first traction roller 6 and the rotating shaft 8, and finally wrapped around the second traction wheel and onto the take-up drum 306. As the take-up drum 306 continues to rotate, the calendered curtain can be wound around the outside of the take-up drum 306 in an orderly manner. When it is necessary to adjust the tension of the curtain, the stepper motor 304 is turned on. As the stepper motor 304 is turned on, the driven shaft is rotated. As the driven shaft rotates, the rotating plate 302 rotates. As the rotating plate 302 rotates, the rotating roller 303 is adjusted in angle. After the angle is adjusted, the curtain passing through it can be tightened.
