Description

Technical Field

[0001] This utility model relates to the field of tire production technology, specifically a tire taking and turning device for a new type of radial tire forming machine. Background Technology

[0002] Radial tires, commonly known as "steel-wire tires," have their ply layers arranged at approximately 90° to the centerline of the tread. They are mainly composed of ply layers and belt layers. Depending on the materials used, they can be divided into three types: all-steel-wire, semi-steel-wire, and all-fiber. They have advantages such as structural stability, resistance to deformation, good cushioning, long service life, and high fuel economy. During the production of radial tires, in order to even out tire wear, improve driving stability and handling, and thus extend tire life and improve vehicle performance, the tires need to be removed and tumbled after forming.

[0003] In existing radial tire picking and flipping devices, the flipping drive cylinder is located on the same side or opposite side of the roller. Because the end of the cylinder rod is placed on the roller side, the lifting and lowering of the cylinder and its related components will affect the lifting height of the flipping mechanism, resulting in a relatively high overall frame of the device. In order to achieve stable flipping of tires of different specifications while further reducing the overall frame height of the device, a new type of radial tire forming machine tire picking and flipping device is provided, which can eliminate the drawbacks of the existing device.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In one embodiment, such as Figures 1-3 As shown, a novel radial tire forming machine's tire taking and turning device includes a top plate 1. Two lifting frames 7 are symmetrically arranged on the outer wall of the top plate 1. Two turning plates 8 are symmetrically arranged below the top plate 1 and are located between the two lifting frames 7. Two clamping plates 6 are symmetrically arranged between the two turning plates 8 and are located at the upper and lower ends of one end of the turning plate 8. Two movable sliding plates 4 are symmetrically fixedly connected to the outer wall of the clamping plates 6. Two first guide rails 5 are symmetrically fixedly connected to the end of the turning plate 8 away from the lifting frames 7. The movable sliding plates 4 are slidably sleeved on the outer wall of the two first guide rails 5. Two second guide rails 9 are symmetrically fixedly connected to one end of the lifting frames 7. Support plates 3 are slidably sleeved on the outer wall of each of the two second guide rails 9. A driving mechanism for driving the clamping plates 6 to clamp and turn the tire is provided on the top plate 1.

[0034] In this embodiment, when the tire moves between the two clamping plates 6, the driving mechanism can make the moving slide plate 4 slide along the outer wall of the first guide rail 5 and drive the clamping plate 6 to contact the outer wall of the tire. This can clamp and limit tires of different specifications, and by squeezing the inner wall of the tire, it can effectively prevent the tire from shifting during the flipping process.

[0035] After the tire is clamped and limited, the lifting frame 7 is driven to rise steadily by the drive mechanism. At the same time, the lifting frame 7 slides along the inner wall of the support plate 3 via the second guide rail 9. At this time, the flipping plate 8 is driven by the lifting frame 7, and the tire is driven to rise synchronously via the moving slide plate 4 and the clamping plate 6. When the tire rises to a suitable height, the flipping plate 8 is flipped by the drive mechanism. At the same time, the moving slide plate 4 is driven by the flipping plate 8, and the tire is flipped via the clamping plate 6. This allows for convenient flipping of tires of different specifications. Then, the flipped tire is driven to descend steadily. This allows for stable flipping of tires of different specifications while further reducing the overall height of the device frame.

[0036] In one embodiment, such as Figures 1-2 As shown, the drive mechanism includes: a lifting assembly mounted on the top plate 1 for driving the lifting frame 7 to rise and fall;

[0037] The lifting assembly includes: a dual-head motor 2013 installed at the top of the top plate 1; a second transmission rod 2012 fixedly connected to each of the two output ends of the dual-head motor 2013; a third gear 2011 fixedly connected to the end of the second transmission rod 2012 away from the dual-head motor 2013; a first rack 2010 meshing with the outer wall of the third gear 2011; the first rack 2010 fixedly connected to the lifting frame 7; and the first rack 2010 slidably connected to the top plate 1. Through the meshing connection between the first rack 2010 and the third gear 2011, the tire can be lifted and lowered by the lifting frame 7, the flip plate 8, the movable slide plate 4, the first guide rail 5, and the clamping plate 6.

[0038] The lifting frame 7 is equipped with a flipping assembly for driving the flipping plate 8 to flip.

[0039] The flip plate 8 is equipped with an adjustment component for adjusting the clamping plate 6 to clamp tires of different sizes.

[0040] The clamping plate 6 is provided with a limiting component for limiting the tire;

[0041] In one embodiment, such as Figures 1-3 As shown, the flipping assembly includes: a second servo motor 204 fixedly connected to one end of a lifting frame 7 away from the flipping plate 8; two second gears 206 symmetrically arranged between the two lifting frames 7; one second gear 206 fixedly connected to the output end of the second servo motor 204; gear rings 203 meshing with the outer walls of both second gears 206; gear rings 203 fixedly connected to the flipping plate 8; a fixed disk 202 fixedly connected to one end of the lifting frame 7; gear rings 203 rotatably sleeved on the outer wall of the fixed disk 202; a limit rotating ring integrally formed on the inner wall of the gear ring 203; and a limit rotating groove for the limit rotating ring to rotate at the contact position between the fixed disk 202 and the limit rotating ring.

[0042] The lifting frame 7 is equipped with a transmission assembly;

[0043] The transmission assembly includes: a first transmission rod 207 disposed between two lifting frames 7, the first transmission rod 207 being located below two second gears 206, the first transmission rod 207 being rotatably connected to the two lifting frames 7, and two first gears 205 being symmetrically fixedly connected to the outer wall of the first transmission rod 207, the two first gears 205 being meshed with the two second gears 206 respectively. Through the cooperation between the flipping assembly and the transmission assembly, tires of different specifications can be automatically flipped through the clamping plate 6.

[0044] In one embodiment, such as Figures 1-3 As shown, the adjustment assembly includes: a first servo motor 201 installed at the top of the flip plate 8; a bidirectional lead screw 209 fixedly connected to the output end of the first servo motor 201; the bidirectional lead screw 209 is located inside the flip plate 8 and is rotatably connected to the flip plate 8; two movable sleeves 2015 are symmetrically sleeved on the outer wall of the bidirectional lead screw 209; both movable sleeves 2015 are threadedly connected to the bidirectional lead screw 209; both movable sleeves 2015 are fixedly connected to two movable slide plates 4; and both movable sleeves 2015 are slidably connected to the flip plate 8. Through the mutual cooperation of the bidirectional lead screw 209 and the movable sleeves 2015, tires of different specifications can be clamped and gripped by two clamping plates 6.

[0045] In one embodiment, such as Figures 1-3 As shown, the limiting assembly includes: two third servo motors 2014 respectively installed at opposite ends of the two clamping plates 6; each of the output ends of the two third servo motors 2014 is fixedly connected to a fourth gear 2017, which is located inside the clamping plate 6; two second racks 2018 are symmetrically meshed on the outer wall of the fourth gear 2017; each of the opposite ends of the two second racks 2018 is fixedly connected to a connecting slide plate 2016; two sets of limiting push rods 208 are symmetrically arranged between the two clamping plates 6, and the two sets of limiting push rods 208 penetrate into the interior of the two clamping plates 6; each set of limiting push rods 208 has two members, and the two limiting push rods 208 are fixedly connected to the two connecting slide plates 2016 respectively; the limiting push rods 208 are slidably connected to the clamping plates 6; the two sets of limiting push rods 208 can compress and limit tires of different specifications, thereby preventing displacement of the tires during the flipping process.

[0046] The above embodiment discloses a novel tire-taking and flipping device for a radial tire forming machine. In use, when the tire moves between the two clamping plates 6, the first servo motor 201 is started to drive the bidirectional lead screw 209 to rotate. At the same time, the moving sleeve 2015 is connected by a thread to the bidirectional lead screw 209 and driven by the rotation, drives the moving slide plate 4 to slide along the outer wall of the first guide rail 5. At this time, the clamping plates 6 are moved synchronously under the drive of the moving slide plate 4 until the outer walls of both clamping plates 6 are in contact with the outer wall of the tire. At this time, the limiting push rod 208 is driven by the clamping plates 6 to move to the inner side of the tire, thereby enabling the initial clamping and limiting of tires of different specifications.

[0047] Then, the third servo motor 2014 is started to drive the fourth gear 2017 to rotate. At the same time, the two second racks 2018, driven by the meshing of the fourth gear 2017, drive the limiting push rods 208 to slide along the inner wall of the clamping plate 6 through the connecting slide plate 2016 until both sets of limiting push rods 208 are in contact with the inner wall of the tire. In this way, the tire can be squeezed and limited by squeezing the inner wall of the tire, effectively preventing the tire from shifting during the flipping process.

[0048] After the tire is clamped and limited, the dual-head motor 2013 is started to drive the two second transmission rods 2012 to rotate. At the same time, the third gear 2011 rotates synchronously under the drive of the second transmission rods 2012. At this time, the first rack 2010 drives the lifting frame 7 to rise steadily under the meshing drive of the third gear 2011. Meanwhile, the lifting frame 7 slides along the inner wall of the support plate 3 through the second guide rail 9. At this time, the flip plate 8 drives the tire to rise synchronously through the moving slide plate 4 and clamping plate 6 under the drive of the lifting frame 7 via the toothed ring 203 and the fixed plate 202.

[0049] When the tire rises to a suitable height, the dual-head motor 2013 stops, and the second servo motor 204 is started to drive a second gear 206 to rotate. At the same time, a first gear 205, driven by a second gear 206, drives another first gear 205 to rotate synchronously through the first transmission rod 207. Meanwhile, the other second gear 206 rotates synchronously under the drive of the other first gear 205. Simultaneously, the two gear rings 203, driven by the meshing of the two second gears 206, rotate along the outer wall of the fixed plate 202 through limit switching. At this time, the flipping plate 8, driven by the gear rings 203, drives the tire to flip through the moving slide plate 4 and clamping plate 6. This allows for convenient flipping of tires of different specifications. Then, the dual-head motor 2013 is started to drive the tire to descend stably. This allows for stable flipping of tires of different specifications while further reducing the overall height of the device frame.

[0050] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
