Description

Technical Field

[0001] The invention relates to the field of tire production equipment, in particular to a tire molding machine. Background Art

[0002] In recent years, the market demand for two-step forming machines has gradually increased due to their high-quality forming quality, and customers' requirements for the forming quality and efficiency of two-step forming machines have also been continuously increasing.

[0003] For the molding of all-steel medium and large-sized engineering radial tires, the leading customers in the market currently mostly adopt the two-step process route, and the tread rubber materials mostly adopt the online extrusion winding process. In large-sized engineering tires, the time occupied by the online extrusion winding of the tread is particularly long. In recent years, the latest two-step five-drum engineering tire molding machine in the industry includes a carcass drum, a turn-up drum, a belt drum and two identical shaping drums, one of which is only used for inflation and shaping, and the other is only used for winding. After the embryo is inflated and shaped on the shaping drum, it is transferred from the winding station through the transfer ring. The embryo is inflated and shaped at the winding station for the second time and then wound. The second inflation and shaping easily cause the embryo to be asymmetric on the left and right, which is more obvious with the larger the tire specifications. The second transfer inflation and shaping causes the embryo to be severely deformed, which affects the quality of the tire. In the prior art, there are mainly two ways to arrange the two shaping drums, one of which is to arrange the shaping and winding stations in parallel. This method not only leads to unstable tire molding quality, but also has the problems of cumbersome steps and long embryo transfer time. The other is that the two shaping drums can rotate 180 degrees and one of the shaping drums is used for shaping the tire, and the other is used for tread winding of the tire blank. This arrangement has the problem of occupying a large area and resulting in low actual utilization rate of the factory.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0027] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0028] In order to solve the problem of poor performance of the molding machine in the prior art, the present invention provides a molding machine.

[0029] like Figure 1 As shown, the forming machine includes a carcass drum assembly 10, a turn-up drum assembly 20, a transfer assembly 30, a belt layer drum assembly 40 and a shaping winding assembly 50, wherein the turn-up drum assembly 20 is located downstream of the carcass drum assembly 10; one end of the turn-up drum assembly 20 away from the carcass drum assembly 10 is connected to one end of the transfer assembly 30 in the length direction; the belt layer drum assembly 40 and the shaping winding assembly 50 are respectively located on both sides of the length direction of the transfer assembly 30, and the shaping winding assembly 50 is close to or away from the carcass drum assembly 10 relative to the belt layer drum assembly 40, and the shaping winding assembly 50 includes a winding structure 51 and two shaping structures 52 arranged at intervals, and at least a portion of the winding structure 51 can move between the two shaping structures 52.

[0030] The rubber material in the present scheme passes through the carcass drum assembly and the turn-up drum assembly in sequence to form a turn-up cylinder, and the belt layer passes through the belt layer drum assembly to form a belt layer cylinder. The transfer assembly 30 transfers the turn-up cylinder and the belt layer cylinder to the shaping structure 52 of the belt layer drum assembly 40 in sequence, and the turn-up cylinder and the belt layer cylinder are inflated and shaped on the shaping structure 52 to form a tire blank. The two shaping structures 52 can shape two tire blanks respectively, and at least a part of the winding structure 51 can move between the two shaping structures 52. The winding structure 51 can wind the tire blanks on the two shaping structures 52 respectively, that is, the tire blanks on each shaping structure 52 can be shaped and wound in sequence. The molding sequence is simple, which reduces the transfer time of the tire blank from the shaping station to the winding station, avoids waiting between the two shaping structures 52, improves work efficiency, and prevents the secondary transfer inflation and shaping from causing serious deformation of the tire blank, so that the tire quality is guaranteed and the production capacity utilization rate is high; in addition, the position of each component is reasonably arranged and the floor space is small.

[0031] The two shaping structures 52 in the present application can both independently receive the turn-up tube and the belt layer tube, and can independently complete the shaping process, avoiding the need for the original structure to complete the shaping process before the next tire blank can be formed, thereby significantly improving the production efficiency of the tire.

[0032] It should be noted that, in the present embodiment, the shaping winding assembly 50 is close to the carcass drum assembly 10 relative to the belt layer drum assembly 40, the shaping winding assembly 50 is located between the carcass drum assembly 10 and the belt layer drum assembly 40, and the transfer assembly 30 is located between the belt layer drum assembly 40 and the shaping winding assembly 50. In other alternative embodiments, the positions of the belt layer drum assembly 40 and the shaping winding assembly 50 can be replaced, that is, the belt layer drum assembly 40 is located between the carcass drum assembly 10 and the transfer assembly 30.

[0033] It should be noted that, in the present embodiment, the carcass drum assembly 10 is arranged at the far right, and the carcass transfer ring 13 transfers the carcass tube from right to left to the turn-up drum assembly 20. In other alternative embodiments, the carcass drum assembly 10 can be arranged at the far left, and the carcass transfer ring 13 transfers the carcass tube from left to right to the turn-up drum assembly 20.

In this way, the shaping drum case 522 can drive the shaping drum body 523 to move along the length direction of the shaping drum case base 521, so as to drive the shaping drum body 523 to remove the turn-up tube or the belt layer tube on the transmission assembly 30, the shaping drum body 523 is inflated and shaped, and the shaping drum pressure roller 524 rolls the outer surface of the tire blank to realize the shaping process.

[0036] It should be noted that, in this embodiment, the belt drum base 41 and the shaping drum chassis base 521 are staggered in the front-to-back direction. In this way, the reasonable layout of the belt drum assembly 40 and the shaping winding assembly 50 is ensured, so that the placement of the belt drum assembly 40 is flexible, and the equipment footprint is greatly reduced. The problem that the placement of the belt drum assembly 40 is not flexible enough due to the original co-linear arrangement of the belt drum base 41 and one of the two shaping drum chassis bases 521 is solved.

[0037] It should be noted that, in the present embodiment, there are two shaping drum pressure rollers 524, which are arranged corresponding to the two shaping drum bodies 523, and the two shaping drum pressure rollers 524 are located on the relatively outer sides of the two shaping drum bodies 523, and the winding machine 512 is located between the two shaping drum bodies 523.

The head of the winding machine 512 moves to the side of the other molding drum body 523 to wind the tire blank on the molding drum body 523. The one-to-two layout realizes continuous winding of two tire blanks by a single extruder 511, which greatly improves the molding efficiency and the continuous utilization rate of the extruder.

[0041] It should be noted that the positional relationship between the extruder 511, the cooling drum 514, the wrapping machine 512 (which can be rotated 180 degrees to wrap on both sides), and the extrusion wrapping conveying device 513 is not fixed and can be placed freely.

[0053] The rubber material is rolled on the carcass drum body 12 of the carcass drum assembly 10 to form a carcass tube and then transferred to the turn-up drum body 22 through the carcass transfer ring 13;

[0054] After the turn-up drum assembly 20 is turned up, pasted, and rolled to form a turn-up drum, the turn-up drum driving box 23 moves along the turn-up drum base 21 to the leftmost end and enters the avoidance position.

[0055] The belt layer is rolled on the belt layer drum body 42 of the belt layer drum assembly 40 to form a belt layer tube. The belt layer transfer ring 322 moves to the tube-taking position. The belt layer drum case 46 places the belt layer tube inside the belt layer transfer ring 322 along the belt layer drum base 41. The belt layer transfer ring 322 receives the belt layer tube and completes the transfer of the belt layer tube from the belt layer drum assembly 40 to the transfer assembly 30.

[0056] The turn-up tube received by the turn-up tube transfer ring 321 of the transfer assembly 30 and the belt layer tube received by the belt layer transfer ring 322 sequentially enter the left side of one of the shaping drum chassis bases 521, and the shaping drum chassis 522 moves to the left to enter the tube taking position, and one of the shaping drum bodies 523 sequentially receives the turn-up tube and the belt layer tube, and the shaping drum chassis 522 moves to the right along the shaping drum chassis base 521, and after the shaping drum body 523 is inflated and the shaping drum pressure roller 524 is rolled, the turn-up tube and the belt layer tube are compounded, and the shaping process is completed, and it is ready to enter the winding process;

[0057] Repeat the above steps, and another shaping drum body 523 receives the turn-up drum and the belt layer drum to complete the shaping process.

[0058] The head of the winding machine 512 completes the winding of the shaping drum body 523 below the shaping winding component 50. The winding machine 512 can rotate 180 degrees to complete the winding of the shaping drum body 523 above the shaping winding component 50. The one-to-two layout can continuously realize the continuous winding of two tire blanks by a single extruder 511.
