Description

Technical Field

[0001] This utility model belongs to the field of tire manufacturing technology, specifically relating to a tire nitrogen vulcanization device. Background Technology

[0002] During the tire production process, a high-temperature vulcanization process is required. Compared with the traditional vulcanization process, nitrogen vulcanization has advantages such as energy saving and high efficiency, and therefore it has been widely used in tire production.

[0003] Existing nitrogen vulcanization equipment for tires generally includes an upper mold, a lower mold, a medium path, a heating device, and a material handling mechanism. The function of the material handling mechanism is to remove the tire from the lower mold after vulcanization. Since the tire is placed flat in the lower mold, conventional mechanical grippers are difficult to remove the tire from the lower mold. Existing material handling mechanisms generally use a hook to hook the inner edge of the tire, and then pull the hook with a rope to bring the tire out. However, in this material handling method, the tire is prone to shaking during the material handling process, the tire has poor stability, and the tire is prone to falling off. Utility Model Content

[0004] The purpose of this invention is to provide a nitrogen vulcanization device for tires to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tire nitrogen vulcanization device, comprising a base, a lower mold, and a material handling mechanism. The lower mold is disposed on the base, and the material handling mechanism comprises a U-shaped frame fixedly mounted on the base, a support plate slidably mounted on the U-shaped frame, a lifting assembly for driving the support plate to rise and fall, a cylinder fixedly mounted on the bottom of the support plate, and a support block slidably mounted around the cylinder.

[0006] A screw is rotatably mounted inside the cylinder, and a first motor for driving the screw to rotate is fixedly mounted on the top of the cylinder. A slider is threadedly connected to the screw, and a support rod is hinged between the slider and four support blocks.

[0007] In a preferred embodiment, the lifting assembly includes a stud rotatably mounted on one side of the U-shaped frame and a second motor for driving the stud to rotate. One end of the support plate is sleeved on the stud and threadedly connected to the stud.

[0008] In a preferred embodiment, the second motor is fixedly mounted on the top of the U-shaped frame.

[0009] In a preferred embodiment, a guide post is fixedly installed on the other side of the U-shaped frame, and the other end of the support plate is slidably sleeved on the guide post.

[0010] In a preferred embodiment, a guide rod is fixedly installed inside the cylinder, and the slider is slidably sleeved on the guide rod.

[0011] In a preferred embodiment, a limiting block is fixedly connected to one end of the support block located inside the cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This tire nitrogen vulcanization device, through the setting of the material handling mechanism, when it is necessary to remove the tire after vulcanization in the lower mold, the support plate can be controlled to descend by the lifting component, so that the support plate drives the lower end of the cylinder to extend into the lower mold. The cylinder will enter the inner ring of the tire. Then, the first motor is started to drive the screw to rotate, so that the screw drives the slider to slide down along the guide rod. The slider can drive the support block to slide and extend around the cylinder through the support rod, so that the support block extends into the tire and abuts against the inner wall of the tire. Then, the support plate is controlled to rise steadily by the lifting component, so that the cylinder with the tire is raised from the lower mold, and the tire can be removed. This improves the stability of the tire material handling process and avoids the tire falling off.

[0014] This tire nitrogen vulcanization device, through the setting of the lifting component, can start the second motor to drive the stud to rotate when controlling the lifting of the support plate. The stud drives the support plate to slide stably along the guide column, ensuring the stability of the tire during the lifting process and preventing the tire from shaking during the lifting process.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3 This utility model provides a nitrogen vulcanizing device for tires, including a base 1, a lower mold 2, and a material handling mechanism 3. The lower mold 2 is mounted on the base 1. The material handling mechanism 3 includes a U-shaped frame 31 fixedly mounted on the base 1, a support plate 32 slidably mounted on the U-shaped frame 31, a lifting assembly 33 for driving the support plate 32 to rise and fall, a cylinder 34 fixedly mounted on the bottom of the support plate 32, and support blocks 35 slidably mounted around the cylinder 34. A screw 36 is rotatably mounted inside the cylinder 34. A first motor 37 for driving the screw 36 to rotate is fixedly mounted on the top of the cylinder 34. A slider 38 is threadedly connected to the screw 36. Support rods 39 are hinged between the slider 38 and each of the four support blocks 35. A guide rod 310 is fixedly mounted inside the cylinder 34, and the slider 38 is slidably sleeved on the guide rod 310. On the 10th, through the setting of the material handling mechanism 3, when it is necessary to remove the tire after vulcanization in the lower mold 2, the support plate 32 can be lowered by the lifting component 33, so that the support plate 32 drives the lower end of the cylinder 34 to extend into the lower mold 2. The cylinder 34 will enter the inner ring of the tire. Then, the first motor 37 is started to drive the screw 36 to rotate, so that the screw 36 drives the slider 38 to slide down along the guide rod 310. The slider 38 can drive the support block 35 to slide and extend around the cylinder 34 through the support rod 39, so that the support block 35 extends into the tire and abuts against the inner wall of the tire. Then, the support plate 32 is raised stably by the lifting component 33, so that the cylinder 34 with the tire is raised from the lower mold 2, and the tire can be removed. This improves the stability of the tire material handling process and avoids the tire falling off.

[0022] Specifically, the lifting assembly 33 includes a stud 331 rotatably mounted on one side of the U-shaped frame 31 and a second motor 332 for driving the stud 331 to rotate. The second motor 332 is fixedly mounted on the top of the U-shaped frame 31. One end of the support plate 32 is sleeved on the stud 331 and threadedly connected to the stud 331. A guide post 333 is fixedly mounted on the other side of the U-shaped frame 31. The other end of the support plate 32 is slidably sleeved on the guide post 333. By setting up the lifting assembly 33, when controlling the lifting of the support plate 32, the second motor 332 can be started to drive the stud 331 to rotate. The stud 331 drives the support plate 32 to slide stably along the guide post 333, ensuring the stability of the tire during the lifting process and preventing the tire from shaking during the lifting process.

[0023] One end of the support block 35 located inside the cylinder 34 is fixedly connected to a limiting block 311. The limiting block 311 can limit the support block 35 and prevent it from falling off the cylinder 34.

[0024] The working principle and usage process of this utility model are as follows: First, when it is necessary to remove the tire after vulcanization in the lower mold 2, the second motor 332 can be started to drive the stud 331 to rotate. The stud 331 drives the support plate 32 to descend along the guide post 333, so that the support plate 32 drives the lower end of the cylinder 34 to extend into the lower mold 2. The cylinder 34 will enter the inner ring of the tire. Then, the first motor 37 is started to drive the screw 36 to rotate, so that the screw 36 drives the slider 38 to slide down along the guide post 310. The slider 38 can drive the support block 35 to slide and extend around the cylinder 34 through the support rod 39, so that the support block 35 extends into the tire and abuts against the inner wall of the tire. Then, the second motor 332 is started to drive the stud 331 to rotate, so that the stud 331 drives the support plate 32 to rise along the guide post 333, so that the cylinder 34 with the tire rises from the lower mold 2, and the tire can be removed. This improves the stability of the tire removal process and avoids the tire falling off.
