Technical Field

[0001] The utility model relates to the technical field of volleyball production, in particular to a volleyball tire rubber coating device. Background Art

[0002] The structure of a volleyball is divided into: liner, yarn wrapping, middle tube and skin. In the production of rubber liner, the three major types of balls are similar. They all use natural rubber to fold, and then use a press to cut out the bladder, and use glue to insert the air valve on the inflation hole. After inflation, it passes through a curing machine and heats and cures a rubber bladder. The next step is yarn wrapping. By putting the freshly baked bladder on a rolling machine and wrapping it with nylon yarn, wrap the bladder with a sufficient amount of yarn wrapping. This step is used for shaping to ensure that the spherical shape of the volleyball remains unchanged. After the yarn-wrapped liner is deflated, it is placed on a hot press where rubber has been placed. After high temperature and pressure, a bladder wrapped with a middle tube can be obtained. Finally, the skin is cut into shape by a cutting machine, and then the skin is attached to the surface of the middle tube according to the corresponding position, and then put into a hot bonding machine, covered with a lid, and inflated. Under the action of high temperature, a volleyball with full elasticity is made.

[0003] In the prior art, a layer of glue needs to be brushed on the outer surface of the middle tire before the volleyball is attached to the skin, so that the middle tire and the skin can be better bonded together, thereby achieving the effect of improving the appearance quality of the volleyball. Most of the processes are done manually. However, since the volleyball is spherical, the surface of the sphere is a curved surface, and its geometric shape is more complex than that of a flat surface. During the manual brushing process, it is difficult to quickly and fully apply the glue to the surface of the sphere, resulting in difficulty in fully bonding the middle tire and the skin, affecting the production quality of the volleyball.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a volleyball tire rubber coating device, comprising: a fixed frame 1, an electric telescopic rod 2 is arranged on the top of the fixed frame 1, and the telescopic end of the electric telescopic rod 2 slides through the top of the fixed frame 1; an adsorption component 4, the adsorption component 4 comprises a base 401, the base 401 is fixedly connected to the inner bottom center of the fixed frame 1, a plurality of support rods 402 are fixedly connected to the top of the base 401 at equal intervals, a mounting plate 403 is fixedly connected to the top of the plurality of support rods 402, a placement block 404 is fixedly connected to the top of the mounting plate 403, a plurality of air holes 406 are opened at equal intervals on the top of the placement block 404, an exhaust pipe 405 is arranged at the bottom center of the mounting plate 403, and the exhaust pipe 405 is connected to the placement block 404; a coating component 3, the coating component 3 is fixedly connected to the telescopic end of the electric telescopic rod 2, the coating component 3 comprises a mounting frame 301 and a transmission belt 306, the mounting frame 301 is fixedly connected to the telescopic end of the electric telescopic rod 2, and the bottom of the mounting frame 301 is close to one side edge A motor 302 is fixedly connected at the bottom, the output end of the motor 302 rotates and penetrates the bottom of the mounting frame 301, the output end of the motor 302 is fixedly connected to a rotating rod 303, the outer surface of the rotating rod 303 is fixedly connected to a first pulley 304, the inner surface wall of the mounting frame 301 is rotatably connected to a connecting pipe 307, a storage tank 309 is set on the top of the connecting pipe 307, an arc-shaped buffer tank 308 is set at the bottom of the connecting pipe 307, and the outer surface of the connecting pipe 307 is fixedly connected to a second pulley 305 The second pulley 305 and the first pulley 304 are connected through a transmission belt 306. The arc-shaped cache tank 308 is located at the bottom center of the mounting frame 301. The arc-shaped cache tank 308 is connected to the connecting pipe 307. The arc-shaped cache tank 308 is arc-shaped. A plurality of through holes 311 are equidistantly provided on the outer surface of the arc-shaped cache tank 308. The bottom of the storage tank 309 is conical. The storage tank 309 is located on the inner side of the mounting frame 301. The storage tank 309 is connected to the connecting pipe 307.

[0024] The effect achieved by the entire embodiment 1 is that when the volleyball tire is coated with glue, the volleyball tire is first filled with gas to expand it into a sphere, and after it is fitted with the inner side of the arc-shaped buffer tank 308, the volleyball tire is supported, and the electric telescopic rod 2 is started. When the telescopic end thereof extends outward, it will drive the supported volleyball tire to move into the arc-shaped groove at the top of the placement block 404 until it touches the arc-shaped groove of the placement block 404, and the external negative pressure generator is started. The external negative pressure generator is used to generate a vacuum through the exhaust pipe 40 5. The placement block 404 is evacuated. Since the bottom of the placement block 404 is fixedly connected to the mounting plate 403 and the bottom is sealed, and the top is pressed against the volleyball tire, negative pressure is generated when the internal gas is evacuated. The volleyball tire in the arc-shaped groove at the top is adsorbed and fixed through multiple air holes 406.

After the application is completed, the electromagnetic valve and the motor 302 are closed in turn, and air is supplied to the interior of the placement block 404 to relieve the internal negative pressure. The telescopic end of the electric telescopic rod 2 retracts and resets, and the personnel can take down the volleyball tire, and they only need to apply it to the smaller adsorption area on the top of the placement block 404 manually, which solves the problem in the background technology that in the process of manual brushing, the volleyball tire is difficult to quickly and fully apply the glue on the ball surface due to its complex geometric curved surface, resulting in difficulty in sufficient adhesion between the tire and the epidermis, affecting the production quality of the volleyball.

[0025] Embodiment 2, as Figure 1-Figure 5 As shown, a fixing rod 310 is fixedly connected to the top of the mounting frame 301 near one side edge, and the outer surface of the fixing rod 310 slides through the inner top of the fixing frame 1 .

[0026] The effect achieved by the entire embodiment 2 is that, when in use, by setting a fixing rod 310 at the top edge of the mounting frame 301, when the mounting frame 301 is being lifted or lowered, the fixing rod 310 will slide up and down accordingly in the inner wall of the fixing frame 1, thereby playing a limiting role, preventing the mounting frame 301 from shifting in position during the lifting or lowering process, affecting the arc-shaped buffer tank 308 from fitting to the surface of the volleyball tire, thereby improving the use effect of the volleyball tire rubber coating device.

[0027] Working principle: When in use, the volleyball middle tire that is inflated into a sphere by filling with gas is fitted with the inner side of the arc-shaped buffer tank 308 to maintain support for it. Since the mounting plate 403 is fixed to the top of the base 401 by a plurality of support rods 402, and the base 401 is fixed to the inner bottom center of the fixing frame 1, corresponding to the position of the bottom center of the mounting frame 301, the electric telescopic rod 2 is started, and when the telescopic end of the electric telescopic rod 2 is extended downward, it will drive the supported volleyball middle tire to move into the top arc-shaped groove of the placement block 404 until it touches and fits into the arc-shaped groove of the placement block 404. The exhaust pipe 405 is connected to the external exhaust device, and the placement block 404 is exhausted through the exhaust pipe 405, so that negative pressure will be generated after the internal gas of the placement block 404 is exhausted, and the volleyball middle tire in the top arc-shaped groove is adsorbed and fixed through a plurality of air holes 406, and the surface of the connecting pipe 307 is opened. The electromagnetic valve is set to connect the connecting pipe 307 with the storage tank 309, and the glue stored inside will flow into the arc-shaped buffer tank 308 along the connecting pipe 307, and seep out from multiple through holes 311, synchronously starting the motor 302, and its output end drives the rotating rod 303 to rotate forward, and the first pulley 304 rotates synchronously, and transmits the second pulley 305 through the transmission belt 306, thereby driving the connecting pipe 307 to rotate synchronously in the mounting frame 301, and the arc-shaped buffer tank 308 connected to the bottom will rotate in contact with the surface of the volleyball tire, and the seeped glue will be evenly spread on the surface of the volleyball tire under the action of rotation. After the coating is completed, the reverse operation can facilitate the personnel to remove the volleyball tire, so that most of the curved surface of the volleyball tire is automatically and fully coated, and manual coating only needs to be applied to the smaller adsorption area on the top of the placement block 404, thereby improving the coating effect of the volleyball tire coating device.
