DETAILED DESCRIPTION
[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Specific examples are given below.
[0026] See also Figure 1 - Figure 5The utility model provides a fixing structure for a semi-steel tire building machine, comprising a support frame 1, wherein a plurality of electric push rods 11 are fixedly connected to the side wall of the support frame 1; a first connecting plate 12 is fixedly connected to the end of the electric push rod 11; a servo motor 13 is fixedly connected to the top of the outer wall of the first connecting plate 12; the first connecting plate 12 is in sliding contact with the support frame 1; a first bidirectional screw 15 is fixedly connected to the output end of the servo motor 13; a support ring 14 is fixedly connected to the outer wall of the first connecting plate 12; the side wall of the support ring 14 is rotatably connected to the first bidirectional screw 1 5; The side wall of the first bidirectional screw 15 is threadedly connected to a pair of support plates 16; the outer side wall of the support plate 16 is provided with a pair of extrusion plates 18; the extrusion plate 18 is bolted to the support plate 16 by fixing bolts 17; the outer side wall of the support plate 16 is fixedly connected to a pair of first fixing plates 19; the outer side wall of the first fixing plate 19 is fixedly connected to the first spring 10; the side wall of the first spring 10 is fixedly connected to the contact plate 101; the inner side wall of the extrusion plate 18 is rotatably connected to the contact plate 101; the side wall of the contact plate 101 is fixedly connected to the limit block 102. When the servo motor 13 is started, the output end of the servo motor 13 drives the first bidirectional screw 15 to rotate, thereby making the two support plates 16 approach each other. When the tire contacts the contact plate 101, the tire changes the contact plate 101 from an inclined state to a vertical state, and the limit block 102 contacts the inner edge of the tire. The limit block 102 plays an auxiliary fixing role for the tire. When the first bidirectional screw 15 rotates, the extrusion plates 18 will approach each other, forming an extrusion force on the tire, thereby fixing the tire. At this time, the electric push rod 11 is started again. When the electric push rod 11 retracts, the position of the tire changes. At this time, the tire can be moved. By setting the first bidirectional screw 15 and the extrusion plate 18, when the tire needs to be taken out after forming, the equipment can provide a fixing force to the tire, reduce the situation of the tire falling when it is taken out after forming, reduce the difficulty of the staff in taking out the tire, and facilitate the staff to use the equipment.
[0027] Further, such as Figure 3As shown, the top of the outer wall of the extrusion plate 18 is fixed with a support column 2; the outer wall of the support plate 16 is fixed with a pair of second fixed plates 21; the side wall of the second fixed plate 21 is rotatably connected with a second bidirectional screw 22; the second bidirectional screw 22 is threadedly connected to the support column 2; one end of the second bidirectional screw 22 is fixed with a turntable 23; the side wall of the support column 2 is fixed with a slider 24; a pair of first sliding grooves 25 are opened inside the support plate 16; the first sliding groove 25 is in sliding contact with the support column 2; a second sliding groove 26 is opened inside the support plate 16; the slider 24 is in sliding contact with the second sliding groove 26. When encountering tires of different sizes, the staff can rotate the turntable 23 to rotate the support column 2. At this time, the two support columns 2 will move away from each other, and then the extrusion plates 18 will move away from each other. Through the provided second bidirectional screw 22 and slider 24, the extrusion plate 18 can move smoothly to both sides, so that the equipment can adapt to tires of different widths. When the equipment encounters tires of different widths, the staff can adjust the equipment according to actual conditions, which is convenient for the staff to use the equipment.
[0028] Further, such as Figure 1 As shown, the outer wall of the support frame 1 is fixedly connected to a second connecting plate 3; the side wall of the second connecting plate 3 is fixedly connected to a spring column 31; the side wall of the spring column 31 is fixedly connected to a push plate 32; the outer wall of the push plate 32 is fixedly connected to a curved plate 33; the push plate 32 does not contact the first connecting plate 12. When the equipment is working, the first connecting plate 12 will move, and the tire will move along with it. When the tire contacts the curved plate 33, the tire will squeeze the curved plate 33 and the push plate 32. At this time, the spring column 31 will contract. When the squeezing plate 18 is separated from the tire, the tire loses the force that holds it in place. At this time, the spring column 31 will push the push plate 32 and the curved plate 33, and then push the tire to the other side, causing the tire to detach from the equipment. The provision of the spring column 31 allows the tire to detach quickly from the equipment, reducing the difficulty for workers to use the equipment.
[0029] Further, such as Figure 2 and Figure 4 As shown, a brush plate 4 is fixedly connected to the outer wall of the support plate 16; a plurality of bristles 41 are fixedly connected to the outer wall of the brush plate 4; and the bristles 41 are in contact with the first bidirectional screw 15. When the device is in operation, the first bidirectional screw 15 rotates, and the support plate 16 drives the bristles 41 to move. The bristles 41 clean dust and impurities adhering to the side wall of the first bidirectional screw 15. The provision of the bristles 41 can reduce the amount of dust and impurities on the side wall of the first bidirectional screw 15, thereby reducing the possibility of equipment jamming or malfunctioning due to dust and impurities during operation, and reducing the failure rate of the equipment.
[0030] Further, such as Figure 2As shown, a support block 5 is fixedly attached to the outer wall of the first connecting plate 12; the support block 5 is rotatably connected to the first bidirectional screw 15; and the support block 5 is positioned relatively centrally on the first bidirectional screw 15. During operation, the support block 5 provides support for the first bidirectional screw 15. The presence of the support block 5 reduces the risk of bending of the first bidirectional screw 15 during prolonged operation, thereby reducing the probability of equipment failure due to bending and improving equipment stability.
[0031] Further, such as Figure 5 As shown, the material of the limit block 102 is rubber. When the device is working, the limit block 102 will come into contact with the tire. By setting the limit block 102 to be rubber, the probability of the tire surface being scratched when the limit block 102 contacts the tire is reduced.
[0032] Further, such as Figure 3 As shown, several scrapers 7 are fixedly attached to the outer wall of the rotating disk 23; the scrapers 7 come into contact with the palms of the staff. When the equipment is in operation, the staff will rotate the rotating disk 23, and the scrapers 7 will preferentially come into contact with the staff's palms, scraping off sweat or other liquids adhering to the staff's palms. The provision of the scrapers 7 reduces the probability of the staff slipping due to sweat or other liquids when rotating the rotating disk 23, thus facilitating the staff's use of the equipment.
[0033] Working principle: When the servo motor 13 is started, the output end of the servo motor 13 drives the first bidirectional screw 15 to rotate, thereby making the two support plates 16 approach each other. When the tire contacts the contact plate 101, the tire changes the contact plate 101 from an inclined state to a vertical state, and the limit block 102 contacts the inner edge of the tire. The limit block 102 plays an auxiliary fixing role for the tire. When the first bidirectional screw 15 rotates, the extrusion plates 18 will approach each other, forming an extrusion force on the tire, thereby fixing the tire. At this time, the electric push rod 11 is started again, and the tire position changes when the electric push rod 11 retracts. At this time, the tire can be moved. By setting the first bidirectional screw 15 and the extrusion plate 18, when the tire needs to be taken out after forming, the equipment can provide a fixed force to the tire, thereby reducing the tire after forming. This reduces the difficulty of tire removal and makes it easier for workers to use the device. When encountering tires of different sizes, workers can rotate the turntable 23 to rotate the support columns 2. At this time, the two support columns 2 will move away from each other, and in turn, the extrusion plates 18 will move away from each other. The second bidirectional screw 22 and slider 24 allow the extrusion plates 18 to move smoothly to both sides, allowing the device to adapt to tires of different widths. When encountering tires of different widths, workers can adjust the device according to actual conditions, making it easier for workers to use the device. When the device is operating, the first connecting plate 12 will move, and the tire will move with it. When the tire contacts the curved plate 33, the tire will squeeze the curved plate 33 and the push plate 32.At this time, the spring column 31 contracts, and when the extrusion plate 18 separates from the tire, the tire loses the force of being fixed. At this time, the spring column 31 will push the push plate 32 and the arc plate 33, and then push the tire to the other side, so that the tire is separated from the equipment. The spring column 31 is set, so that the tire can be quickly separated from the equipment, reducing the difficulty of the staff in using the equipment. When the equipment is working, the first bidirectional screw 15 will rotate. At this time, the support plate 16 will drive the brush 41 to move, and the brush 41 will clean the dust and impurities attached to the side wall of the first bidirectional screw 15. The brush 41 is set, and the amount of dust and impurities on the side wall of the first bidirectional screw 15 can be reduced, reducing the phenomenon of jamming or malfunction of the equipment during operation due to dust and impurities, and reducing the failure rate of the equipment. When the equipment is working, the support block 5 can 15 provides support force. The support block 5 reduces the risk of bending of the first bidirectional screw 15 during prolonged operation, lowering the probability of equipment failure due to bending and increasing equipment stability. When the equipment is operating, the limit block 102 contacts the tire. The rubber material of the limit block 102 reduces the probability of the tire surface being scratched when the limit block 102 contacts the tire. When the equipment is operating, the operator rotates the turntable 23, and the scraper 7 preferentially contacts the operator's palm. The scraper 7 can scrape away sweat or other liquids adhering to the operator's palm. The scraper 7 reduces the probability of slipping caused by sweat or other liquids when the operator rotates the turntable 23, making it easier for the operator to use the equipment.
