The guide component and the adsorption component cooperate with each other to overcome the problems that when the length of the existing steel wire composite rubber material storage ring is relatively large, the rubber material is stretched and deformed due to its own gravity, the density of the internal steel wire arrangement is uneven, and stress exists inside the rubber material, and the length of the rubber material changes continuously, which leads to a decrease in the precision of fixed-length cutting, and the material heads cannot be butt-jointed after bonding, requiring manual processing, resulting in reduced production efficiency, and at the same time, the dynamic balance performance of the tire is reduced.

Description

Technical Field

[0001] The utility model belongs to the technical field of tire manufacturing, in particular to a steel wire composite rubber material storage ring anti-stretching device of a radial tire building machine. Background Art

[0002] In the prior art, the rolled rubber is generally guided away by a guiding machine and then supplied to the corresponding conveying template for forward conveying. Since the conveying template generally runs at a high speed, and the guiding machine often guides away the rolled rubber, which results in insufficient supply, a rubber storage ring is generally set up between the guiding machine and the rubber conveying template. When the conveying template is started, the rubber on the storage ring will be first supplied to the conveying template. By setting up a rubber length detection device for the storage ring, it can be ensured that when the rubber length of the storage ring is less than the set length, the guiding machine is started to guide the rolled rubber and supply it to the storage ring. When the rubber length of the storage ring is greater than or equal to the set length, the guiding machine stops supplying, and the cycle is repeated. In this way, it can be ensured that the feeding speed of the guiding machine can meet the running speed of the conveying template, and at the same time, it can be ensured that when the conveying template stops running, the length of the storage ring is restored to the set length. However, when the height difference between the conveying template and the feed port of the guide car is too large, the length of the upward conveying section of the storage ring becomes very large. The rubber in this section will be stretched and deformed due to its own gravity, and the steel-wire composite rubber such as the belt layer and the wire wrap contains steel wire. The arrangement density of the rubber will become uneven after deformation. At the same time, there is stress inside the rubber, and the length of the rubber is constantly changing, which leads to a decrease in the precision of fixed-length cutting. After bonding, the material heads cannot be docked and need manual processing, resulting in reduced production efficiency and a decrease in the dynamic balance performance of the tire.

[0012] Further preferably, the surface of the limiting plate is provided with a Teflon coating.

[0013] The beneficial effects of using the utility model are:

[0014] When the length of the upward conveying section of the steel wire composite rubber storage ring is very long, when the conveying template stops running and the length of the storage ring recovers to the set length, the two moving frames pushed by the two first cylinders respectively extend out, driving the two limit plates to extend and contact the bottom of the rubber, and at the same time, the two magnetic blocks pushed by the two second cylinders respectively extend out, so that the magnetic block cover contacts the bottom surface of the limit plate groove. Due to the magnetism of the magnetic block, the rubber with steel wire inside will be adsorbed on the surface of the limit plate through the limit plate. Since the two adsorption groups are arranged up and down on the side plate, it will ensure that this section of rubber will not fall downward due to its own gravity, avoiding a series of consequences caused by stretching deformation, greatly reducing manual processing time, improving production efficiency, and improving tire dynamic balance performance.

[0023] The frame is composed of side panels 2 and mounting plates 3. In the present embodiment, there are two side panels 2 and two mounting plates 3. The two side panels 2 are connected by two mounting plates 3 placed one above the other. One of the side panels 2 is fixed to the equipment column 4 through a mounting bracket 1. A guide assembly is installed on one side of the two side panels 2 located on the rubber supporting surface. The guide assembly is composed of a plurality of guide groups. In the present embodiment, there are five guide groups, wherein the guide group is composed of a Furley wheel 5, a nylon spacer 6, a shaft 7 and a locking retaining ring 8. The shaft 7 is fixed between the two side panels 2 through a locking retaining ring 8. A plurality of Furley wheels 5 are fixedly installed on the shaft 7 through a locking retaining ring 8. In the present embodiment, there are ten Furley wheels 5, and each of the Furley wheels 5 is provided with nylon spacers 6 on both sides.

[0024] In this embodiment, the adsorption assembly is composed of two adsorption groups, which are installed on the two mounting plates 3, and the adsorption end of the adsorption group moves toward the rubber supporting surface. The adsorption group includes a first cylinder plate 9, a first cylinder 10, a limit plate 11, a movable frame 12, a magnetic block cover 13, a magnetic block 14, a magnetic block plate 15, a transition plate 16, a second cylinder 17 and a second cylinder plate 18. The first cylinder plate 9 is installed on the mounting plate 3, the first cylinder plate 9 is installed with the first cylinder 10, the upper part of the first cylinder 10 is installed with the movable frame 12, the movable frame 12 is connected to the front end plate of the first cylinder 10, the movable frame 12 is located on one side of the rubber supporting surface and is installed with the limit plate 11, when the piston rod of the first cylinder 10 is extended, it drives The movable frame 12 extends out, thereby driving the limit plate 11 to extend out and contact the rubber material; a second cylinder plate 18 is installed on the upper surface of the movable frame 12, a second cylinder 18 is installed above the second cylinder plate 18, a transition plate 16 is installed on the front end plate of the second cylinder 17, a magnetic block plate 15 is installed on the transition plate 16, a groove is provided at the center of the magnetic block plate 15, a magnetic block 14 is installed at the groove, and a magnetic block cover 13 is provided on the magnetic block plate 15 at the magnetic block 14; wherein a groove is opened in the limit plate 11 corresponding to the position of the magnetic block cover 13, when the piston rod of the second small cylinder 17 extends out, the magnetic block plate 15 is pushed out, so that the magnetic block cover 13 contacts the bottom surface of the groove of the limit plate 11, and then the magnetism of the magnetic block 14 adsorbs the rubber material with steel wire on the surface of the limit plate 11.

[0025] In this embodiment, the surface of the limiting plate 11 in contact with the rubber material is provided with a Teflon coating.

[0026] In this embodiment, it should be noted that the limiting plate 11, the magnetic block cover 13 and the magnetic block plate 15 are made of non-ferromagnetic materials.

[0027] The working state and principle of the utility model are as follows:

[0028] When the device is not in operation, Figure 1 As shown, the rubber material is continuously transported from the guide car 19 to the rubber material transport template 20 through the material storage ring, the piston rods of the two first cylinders 10 and the two second cylinders 17 are all in a retracted state, the two limit plates 11 and the two magnetic blocks 15 are also in a retracted state, and the rubber material storage ring is blocked by the guide group composed of the Furley wheel 5, the nylon spacer 6, the shaft 7 and the locking retaining ring 8, and does not contact the two limit plates 11;

[0029] When the device is in operation, Figure 2As shown, the rubber material conveying template 20 stops running, and the guide drive 19 stops guiding the rubber material at the storage ring after reaching the set length. At this time, the rubber material is in a stationary state. At this time, the piston rods of the two first cylinders 10 extend, respectively push the two moving frames 12 to extend, drive the two limit plates 11 to extend and contact the rubber material, and at the same time, the piston rods of the two second cylinders 17 extend, respectively push the two magnetic block plates 15 to extend, so that the two magnetic block covers 13 contact the bottom surface of the groove of the limit plate 11. The magnetism will adsorb the rubber with steel wire inside on the surface of the limit plate 11. Since the two limit plates 11 are arranged up and down on the large side plate 2, it will ensure that this section of rubber will not fall down due to its own gravity. When the rubber conveying template 20 is ready to start operation, the piston rods of the two second cylinders 17 will retract first, dragging the two magnetic blocks 15 to retract. Because the two limit plates 11 are made of non-ferromagnetic material, the two magnetic blocks 15 will not be adsorbed on the bottom of the grooves of the two limit plates 11, so the two The piston rod of the second cylinder 17 can be retracted smoothly and detected in place by the magnetic switch, and then the piston rods of the two first cylinders 10 are retracted, dragging the two moving frames 12 to retract respectively, and driving the two limit plates 11 to retract. Because the surfaces of the two limit plates 11 in contact with the rubber are coated with Teflon, they will not stick to the rubber. When the piston rods of the two first cylinders 10 are retracted and detected in place by the magnetic switch, the rubber conveying template 20 starts to operate, and the material storage ring starts to feed the rubber conveying template 20. At the same time, the guide car 19 enters the working state and starts the feeding cycle, thereby ensuring that the rubber conveyed upward will not fall downward due to its own gravity in a static state, avoiding the uneven density of the internal steel wire arrangement caused by stretching deformation, stress inside the rubber, and the continuous change of the length of the rubber, which leads to a decrease in the precision of fixed-length cutting, and the material heads cannot be docked after bonding, requiring manual processing, resulting in a series of consequences such as reduced production efficiency and reduced dynamic balancing performance of the tire, greatly reducing the manual processing time, improving production efficiency, and improving the dynamic balancing performance of the tire.

[0030] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
