[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Specific embodiments are given below.

[0026] Such as Figures 1-5As shown in the figure, a tire unloading device for a semi-steel tire molding machine includes a working frame 1; a molding machine main body 11 is installed at the end of the working frame 1; an electric push rod 12 is installed on the side wall of the molding machine main body 11, and the output end of the electric push rod 12 is slidably arranged in the middle of the working frame 1; a workpiece 13 is installed at the end of the electric push rod 12; a groove 14 is opened in the middle of the working frame 1; a toothed block 15 is rotatably connected to the inner wall of the groove 14, and the toothed block 15 is meshed with the output end of the electric push rod 12; a slide rail 16 is slidably connected to the outer wall of the working frame 1, and the inner wall of the slide rail 16 is meshed with the toothed block 15; a push plate 17 is fixedly connected to the end of the slide rail 16; during operation, the operator needs to assemble the working frame 1 and the molding machine main body 11 together and install them in a designated area, and then connect the power supply to both of them so that the electric push rod 12 can move normally. Subsequently, the tire to be processed can be sleeved on the middle of the workpiece 13, and after starting the switch of the electric push rod 12, the edge of the workpiece 13 can be made to contact the inner wall of the working frame 1. By providing a rotatable toothed block 15 in the middle of the working frame 1, when the tire needs to be removed from the middle of the workpiece 13 subsequently, the switch of the electric push rod 12 can be started again, so that the output end of the electric push rod 12 retracts inward. At the same time, it will drive the toothed block 15 to rotate on the inner wall of the groove 14, and the slide rail 16 will slide in the reverse direction, and the push plate 17 will gradually approach the middle of the fixed tire. After continuously pushing the push plate 17, the push plate 17 will contact the tire and evenly push the tire fixed in the middle of the workpiece 13 to take it out. This step, combined with the provided push plate 17, can reduce the large friction force between the workpiece 13 and the inner wall of the tire, so as to avoid the trouble in subsequent removal and the problem of damage to the edge of the tire caused by directly prying it out with external tools. Under the overall action of the push plate 17, the uniform force of pushing the tire can be improved.

[0027] As Figures 3-4As shown, multiple groups of housings 2 are fixedly connected to the middle of the push plate 17; a spring 21 is fixedly connected to the inner wall of the housing 2; the end of the spring 21 is fixedly connected to a slider 22, and the slider 22 is slidably arranged in the middle of the push plate 17; a first connecting rod 23 is fixedly connected to the middle of the slider 22, and the first connecting rod 23 is arranged inside the inner wall of the spring 21; the first connecting rod 23 is slidably arranged on the inner wall of the housing 2; the end of the first connecting rod 23 is fixedly connected to a scraper 24, and the inner wall of the scraper 24 is arranged to match the shape of the workpiece 13; during operation, by arranging multiple sliders 22 in the middle of the push plate 17, when the push plate 17 approaches the middle of the tire, the end of the slider 22 will be stressed and squeeze the middle of the spring 21 to deform until the whole slider 22 is received inside the inner wall of the push plate 17. At the same time, after continuously sliding the push plate 17, the inner wall of the scraper 24 will come into contact with the surface of the workpiece 13 and scrape off the colloidal material or impurities accumulated on its surface. After the middle of the push plate 17 is separated from the tire, the multiple sliders 22 can lose the supporting force and quickly reset under the action of the spring 21, causing the middle of the scraper 24 to hit the edge of the housing 2 and generate a vibration force to clean the impurities accumulated on the inner wall of the scraper 24. This step, under the action of the scraper 24, can improve the cleanliness of the workpiece 13 after use and reduce the problem of a large resistance when the tire is sleeved on the middle of the workpiece 13 later. The elastic spring 21 can cause the scraper 24 to vibrate frequently after use, thereby improving the cleaning accuracy of the scraper 24 for the workpiece 13 later.

[0028] As Figure 2 and 5 As shown, an inner cavity box 3 is fixedly connected to the outer wall of the workbench 1; a second connecting rod 31 is slidably connected to the inner wall of the inner cavity box 3, and the end of the second connecting rod 31 is fixedly connected to the end of the slide rail 16; the other end of the second connecting rod 31 is fixedly connected to a piston plate 32, and the piston plate 32 is slidably arranged on the inner wall of the inner cavity box 3; a conduit 33 is arranged at the end of the inner cavity box 3, and the conduit 33 is communicated with the inner cavity box 3; during operation, by arranging the inner cavity box 3 on the outer wall of the workbench 1, when the slide rail 16 makes a reciprocating motion, its end will synchronously drive the second connecting rod 31 to move. Under the action of the piston plate 32, the second connecting rod 31 can quickly discharge the gas inside the inner wall of the inner cavity box 3 and generate a wind force to be discharged from the end of the conduit 33, thereby cleaning the inner groove of the output end of the electric push rod 12. Repeating this process, this step, under the action of the wind force discharged from the conduit 33, can improve the cleanliness of the inner groove of the electric push rod 12 and reduce the problem that some dropped impurities directly accumulate on the middle of the electric push rod 12 and form lumps after long-term accumulation, resulting in a large resistance and wear when the electric push rod 12 meshes with the tooth block 15 later.

[0029] As Figures 3-4As shown, a rotating shaft 4 is rotatably connected to the middle of the scraping blade 24; two groups of connecting ropes 41 are fixedly connected to the middle of the rotating shaft 4; a counterweight 42 is fixedly connected to the end of the connecting rope 41; during operation, by arranging a rotating rotating shaft 4 in the middle of the scraping blade 24, when the scraping blade 24 moves, under the action of inertial movement, the counterweight 42 can swing, and then reset and impact on the middle of the scraping blade 24, and part of the impurities accumulated in the middle of the scraping blade 24 are cleaned. This step, combined with the impact force generated by the arranged counterweight 42, can improve the cleanliness of the middle of the scraping blade 24, reduce the accumulation of a large amount of impurities at the blade edge in the middle of the scraping blade 24, avoid troubles when cleaning the workpiece 13 subsequently, and at the same time reduce the problem that the scraping blade 24 is corroded by the accumulation of a large amount of impurities and rusts.

[0030] As Figure 5 shown, a threaded groove 5 is formed in the middle of the conduit 33; a support block 51 is fixedly connected to the outer wall of the inner cavity box 3, and the support block 51 is in threaded connection with the threaded groove 5; during operation, by arranging a threaded groove 5 in the middle of the conduit 33, when the staff needs to adjust the working angle or length of the conduit 33, they can rotate the middle of the conduit 33, so that the conduit 33 rotates at the inner wall of the support block 51 after being stressed, and then the adjustment of the angle or length is completed. This step, combined with the arranged threaded groove 5, can improve the flexibility of the conduit 33 during operation and reduce the problem that the conduit 33 can only clean the inner groove of the electric push rod 12 at the same angle and there are many cleaning blind spots.

[0031] As Figure 5 shown, a filter screen 6 is fixedly connected to the end of the conduit 33; during operation, by arranging a breathable filter screen 6 at the end of the conduit 33, when the piston plate 32 slides in the reverse direction, the conduit 33 will absorb the external gas towards the inner wall of the inner cavity box 3, and the filter screen 6 can block the impurities contained in the external gas. This step, combined with the arranged filter screen 6, can directly transfer a large amount of impurities to the inner wall of the inner cavity box 3 or the conduit 33, avoid the problem that the conduit 33 is blocked after long-term operation, and improve its use stability.

[0032] As Figure 4 shown, a gasket 7 is fixedly connected to the middle of the slider 22; during operation, by arranging a gasket 7 made of soft material in the middle of the slider 22, when the push plate 17 gradually approaches the middle of the tire, the gasket 7 will first contact the middle of the tire. This step, combined with the arranged gasket 7, can reduce the direct contact between the slider 22 and the surface of the rubber tire, and avoid the problem of large scratches on the tire after a long time.

[0033] Working principle: After assembling the working frame 1 and the main body 11 of the molding machine together and installing them in the designated area, and connecting the power supply to both of them, the electric push rod 12 can move normally. Subsequently, the tire to be processed can be sleeved on the middle part of the workpiece 13. After starting the switch of the electric push rod 12, the edge of the workpiece 13 can be made to contact the inner wall of the working frame 1. By arranging a rotatable tooth block 15 in the middle of the working frame 1, when the tire needs to be removed from the middle of the workpiece 13 subsequently, the switch of the electric push rod 12 can be started again, so that the output end of the electric push rod 12 retracts inward. At the same time, it will drive the tooth block 15 to rotate on the inner wall of the groove 14, and the slide rail 16 will slide in the reverse direction, and the push plate 17 will gradually approach the middle of the fixed tire. After continuing to push the push plate 17, the push plate 17 will contact the tire and evenly push the tire fixed in the middle of the workpiece 13 to take it out. By arranging a plurality of sliders 22 in the middle of the push plate 17, when the push plate 17 approaches the middle of the tire, the end of the slider 22 will be stressed and squeeze the middle of the spring 21 to deform until the whole slider 22 is received at the inner wall of the push plate 17. At the same time, after continuing to slide the push plate 17, the inner wall of the scraper 24 will contact the surface of the workpiece 13 and scrape off the colloidal material or impurities accumulated on its surface. After the middle of the push plate 17 is separated from the tire, the plurality of sliders 22 will lose the supporting force and quickly reset under the action of the spring 21, so that the middle of the scraper 24 will hit the edge of the housing 2 and generate a vibration force to clean the impurities accumulated on the inner wall of the scraper 24. By arranging an inner cavity box 3 on the outer wall of the working frame 1, when the slide rail 16 makes a reciprocating motion, its end will synchronously drive the second connecting rod 31 to move. Under the action of the piston plate 32, the second connecting rod 31 can quickly discharge the gas in the inner wall of the inner cavity box 3 and generate wind to be discharged from the end of the conduit 33, so as to clean the inner groove of the output end of the electric push rod 12. This is repeated in turn. By arranging a rotating rotating shaft 4 in the middle of the scraper 24, when the scraper 24 moves, under the action of the moving inertia, the counterweight block 42 can swing, and then reset and hit the middle of the scraper 24 to clean some of the impurities accumulated in the middle of the scraper 24. By arranging a thread groove 5 in the middle of the conduit 33, when the staff needs to adjust the working angle or length of the conduit 33, they can rotate the middle of the conduit 33, so that the conduit 33 is stressed and rotates on the inner wall of the support block 51, thereby completing the adjustment of the angle or length. By arranging a breathable filter screen 6 at the end of the conduit 33, when the piston plate 32 slides in the reverse direction, the conduit 33 will absorb the external gas into the inner wall of the inner cavity box 3, and the filter screen 6 can block the impurities contained in the external gas. By arranging a gasket 7 made of soft material in the middle of the slider 22, when the push plate 17 gradually approaches the middle of the tire, the gasket 7 will first contact the middle of the tire for work.
