Description

Technical Field

[0001] The invention relates to the technical field of tire processing, and in particular to a forming machine pressure roller device and a forming machine. Background Art

[0002] In the production process of all-steel tires, after the composite parts are bonded on the carcass drum, a set of rollers needs to be extended to the carcass drum to roll along the joints of the composite parts to make the joints firmly bonded; after the cord is bonded on the carcass drum, two sets of rollers need to be extended to the middle part of the carcass drum while the carcass drum rotates, and the rollers are separated from the middle to both sides to complete the rolling of the cord to discharge the gas under the cord so that the cord and the lower layer of rubber are tightly bonded. The above two types of rollers are usually realized by different proportional valves controlling different cylinders, and are installed above or below the feed rack, which is costly and occupies a large space.

[0003] The existing technical solution is usually to arrange the composite pressure roller above the carcass drum, supported by a separate frame or installed on the composite laminating template. After the composite laminating is completed, the joint is positioned above the drum for joint laminating. The cord pressure roller is installed at the lower rear of the carcass drum, and the cord is rolled by the cord pressure roller after the laminating is completed. This method occupies a large space, the equipment is not compact enough, the space above the drum is occupied, which reduces the scalability of other parts of the equipment, the pressure roller is installed at a high place, the maintainability is poor, and the cost is high. Both sets of cylinders require proportional valves to adjust the pressure in real time, and both require drive motors that move left and right.

[0004] There is another technical solution, which is to install both the composite roller and the cord roller under the rear of the carcass drum. The two rollers share a frame support and are driven by two independent cylinders and motors. This method simply combines the two rollers together and supports them by the same frame. The rollers with two functions are still independent, and the space occupied is still large. Moreover, they are driven by different drive cylinders and motors. The cost has not changed significantly compared with the previous solution and is still high. In addition, the height of the two rollers is relatively high after the simple combination, which occupies a large space under the feed rack, making the feed rack less expandable. Summary of the invention

[0005] The main purpose of the present invention is to provide a forming machine pressure roller device and a forming machine, so as to solve the problem that the composite pressure roller and the curtain pressure roller of the forming machine in the prior art occupy a large space.

[0009] Furthermore, there are multiple second pressing rollers, the first pressing roller is located between two second pressing rollers, and one side edge of the first pressing roller extends out of the same side edge of the second pressing roller.

[0010] Furthermore, the first pressing roller and the second pressing roller are arranged in a herringbone shape.

[0012] Furthermore, the forming machine pressure roller device also includes a moving mechanism, which is connected to the rotating mechanism and can drive the rotating mechanism, the first bracket, the first pressure roller, and the second pressure roller to move as a whole toward or away from the carcass drum.

In this way, the rolling of the composite part and the rolling of the cord on the carcass drum can be achieved through a set of devices, which greatly reduces the overall size of the device and makes the molding machine equipment compact. The pressure rollers with two functions can be installed on a large cylinder and switched freely, and the space occupancy is greatly reduced, which reserves space for the functional expansion of the feeding system.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] In order to solve the problem that the composite component pressure roller and the curtain fabric pressure roller of the molding machine in the prior art occupy a large space, the present invention provides a molding machine pressure roller device and a molding machine.

[0031] like Figures 1 to 6 A forming machine roller device shown in the figure includes a first bracket 10, a first roller 20, a second roller 30 and a rotating mechanism 40, wherein the first roller 20 is rotatably arranged on the first bracket 10; the second roller 30 is rotatably arranged on the first bracket 10, and the rotation axis of the first roller 20 and the rotation axis of the second roller 30 are not arranged parallel; the rotating mechanism 40 is drivingly connected to the first bracket 10, and can drive the first bracket 10, the first roller 20, and the second roller 30 to rotate as a whole, and make one of the first roller 20 and the second roller 30 face the tire drum 50.

[0032] In this embodiment, the first pressure roller 20 and the second pressure roller 30 are integrated on the first bracket 10, and the first bracket 10 and the components thereon are controlled to rotate as a whole through the rotating mechanism 40, so that the first pressure roller 20 and the second pressure roller 30 switch directions, thereby changing the pressure roller cooperating with the carcass drum 50. In this way, the rolling of the composite part and the rolling of the cord on the carcass drum 50 can be achieved through a set of devices, which greatly reduces the overall size of the device and makes the molding machine equipment compact. The pressure rollers with two functions can be installed on a large cylinder and switched freely, and the space occupancy is greatly reduced, which reserves space for the functional expansion of the feeding system.

[0033] The rotation axis of the first pressing roller 20 of this embodiment is arranged perpendicularly to the rotation axis of the second pressing roller 30, more specifically, they are arranged perpendicularly in space. And because the first pressing roller 20 of this embodiment is used to realize the rolling of the composite part, it is a composite part pressing roller; the second pressing roller 30 is used to realize the rolling of the cord, it is a cord pressing roller, so the rotation axis of the first pressing roller 20 is perpendicular to the axis of the carcass drum 50, and the rotation axis of the second pressing roller 30 is parallel to the axis of the carcass drum 50. Of course, the first pressing roller 20 and the second pressing roller 30 can also be used interchangeably or in other purposes as needed, and the directions of the first pressing roller 20 and the second pressing roller 30 can also be adjusted as needed.

[0034] like Figure 2 and Figure 4 As shown, in this embodiment, there are multiple second rollers 30, the first roller 20 is located between the two second rollers 30, and one side edge of the first roller 20 extends out of the same side edge of the second roller 30. In this embodiment, two second rollers 30 and one first roller 20 are provided, the first roller 20 is located on the mid-perpendicular line of the second roller 30, and one side edge of the first roller 20 extends out of the same side edge of the second roller 30, that is, Figure 2 In the embodiment, the first roller 20 is located at the upper left of the two second rollers 30, and the three rollers are arranged in a herringbone shape. In this way, when the first roller 20 faces the carcass drum 50, the first roller 20 can contact the carcass drum 50, while the second roller 30 will not contact the carcass drum 50, so that the first roller 20 can achieve rolling of the composite part; similarly, when the second roller 30 faces the carcass drum 50, the second roller 30 can contact the carcass drum 50, while the first roller 20 will not contact the carcass drum 50, so that the second roller 30 can achieve rolling of the cord. The above-mentioned setting method can realize that the first roller 20 and the second roller 30 can roll the carcass drum 50 independently, and the two rollers will not affect each other, thereby ensuring the rolling effect of the composite part and the cord. Of course, the positional relationship between the first roller 20 and the second roller 30 can also be adjusted as needed, as long as the two rollers can complete the rolling of the composite part and the cord.

[0035] like Figure 5 and Figure 6As shown, this embodiment adopts a gear rack drive to realize the overall rotation of the first bracket 10. Specifically, the rotating mechanism 40 includes a rotating driving member 41 and a gear rack assembly, the rotating driving member 41 is a driving cylinder, and the gear rack assembly includes a gear 42 and a rack 43 that mesh with each other, wherein the gear 42 is driven and connected to the first bracket 10 through a key, and the two rotate synchronously, and the rack 43 is driven and connected to the cylinder rod of the driving cylinder. When the driving cylinder is activated, the cylinder rod drives the rack 43 to move axially in a straight line, and the rack 43 drives the gear 42 to rotate by meshing with the gear 42, thereby driving the first bracket 10 to rotate 180 degrees as a whole, realizing the change of the matching relationship between the first pressure roller 20 and the second pressure roller 30 and the carcass drum 50, and realizing the function switching between the composite rolling and the cord rolling. The above setting method only needs one set of rotating mechanism 40 to realize the switching of the function of the roller device of the molding machine, so that both the composite pressing and the cord rolling can be realized, and the space occupation is reduced at the same time. Of course, the specific driving method of the rotating mechanism 40 can also be changed as needed, such as using a worm gear or the like.

[0036] In this embodiment, the forming machine pressure roller device also includes a moving mechanism 60, which is connected to the rotating mechanism 40 and can drive the rotating mechanism 40, the first bracket 10, the first pressure roller 20, and the second pressure roller 30 to move as a whole toward or away from the carcass drum 50, so that the pressure roller facing the carcass drum 50 cooperates with the carcass drum 50 to achieve rolling of the composite part or the cord.

[0037] Specifically, Figure 2 , Figure 4 and Figure 5 As shown, the mobile mechanism 60 of this embodiment includes a mobile driving member 61 and a second bracket 62. The mobile driving member 61 is also a driving cylinder, and the movement direction of its cylinder rod coincides with the direction in which the first pressure roller 20 and the second pressure roller 30 approach or move away from the carcass drum 50. The second bracket 62 is connected to the cylinder rod of the mobile driving member 61 by driving, and the rotating mechanism 40 is connected to the second bracket 62. In this way, when the mobile driving member 61 is in motion, the cylinder rod of the mobile driving member 61 drives the second bracket 62 to move, thereby driving the rotating mechanism 40, the first bracket 10, the first pressure roller 20, and the second pressure roller 30 to move toward or away from the carcass drum 50 as a whole through the second bracket 62, so as to realize the rolling of the composite part or the cord. Only one set of the mobile mechanism 60 is needed to drive the movement of the first pressure roller 20 and the second pressure roller 30, thereby reducing the number of mobile mechanisms 60 that need to be set, further reducing the volume occupied, and at the same time, the pressure regulating proportional valves corresponding to the mobile mechanism 60 and other mechanisms are reduced from four to two, thereby reducing the cost. Of course, the specific structural form of the moving mechanism 60 is not limited to the above-mentioned form in this embodiment, and it can also be changed as needed, for example, the driving cylinder is changed to a motor plus a gear rack, etc.

[0038] like Figure 7 As shown, this embodiment also provides a molding machine, including the molding machine pressure roller device mentioned above. In addition, the molding machine also includes a pressure roller driving member 70 and a lead screw 80. The molding machine pressure roller device can be provided with one or more as needed, and is installed on the lead screw 80 through a bracket and other components. In this embodiment, two molding machine pressure roller devices are provided, and the two molding machine pressure roller devices are arranged along the axis of the lead screw 80, and the pressure rollers of the two molding machine pressure roller devices are arranged oppositely. The lead screw 80 is connected to the pressure roller driving member 70 by driving, and the axis of the lead screw 80 is parallel to the axis of the carcass drum 50. When the pressure roller driving member 70 drives the lead screw 80 to rotate, the rotation of the lead screw 80 can drive the molding machine pressure roller device to move along the axial direction of the carcass drum 50. In this way, a set of mechanisms can provide left and right separation and combination power for the two molding machine pressure roller devices, and cooperate with the structural setting of the above molding machine pressure roller device to further reduce space occupancy.

[0039] It should be noted that, the multiple in the above embodiments refers to at least two.

[0040] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0041] 1. Solve the problem that the composite pressure roller and the curtain pressure roller of the molding machine in the prior art occupy a large space;

[0044] 4. Only one set of moving mechanism is needed to drive the movement of both the first pressing roller and the second pressing roller. One set of mechanism can provide left and right separation and combination power for the pressing roller devices of the two forming machines.
