Description

Technical Field

[0001] This utility model belongs to the field of tire processing technology, specifically an automatic tire sidewall return rubber splitting device. Background Technology

[0002] The tire sidewall is the outer surface located between the tire shoulder and the tire bead. It is mainly made of rubber composite material and can transmit force, buffer impact and protect the tire body. It also marks key information such as tire specifications and production date.

[0003] Currently, operators frequently use automatic segmentation devices when removing returned rubber from tire sidewalls. While existing automatic segmentation devices possess basic segmentation functions for tire sidewall returned rubber, there is still room for improvement. When operators guide and segment returned rubber on tire sidewalls of different thicknesses, the device's pressure roller structure is designed with fixed specifications, allowing it to guide tire sidewalls of the same thickness only. It cannot flexibly adjust its height or spacing according to the tire sidewall thickness, resulting in inconsistent guidance for tire sidewalls of different thicknesses. This leads to either misalignment of the segmentation position affecting the returned rubber removal effect, or complete incompatibility with the segmentation operation, thus reducing the device's application range and causing inconvenience for operators handling returned rubber from tire sidewalls of various sizes. Therefore, improvements are needed. Utility Model Content

A gear is fixedly sleeved on the outer surface of the rotating shaft. A toothed plate is movably connected inside the top of the first gantry frame, and the top of the toothed plate passes through the first gantry frame and extends to the outside of the top of the first gantry frame. The toothed plate meshes with the outer surface of the gear. A limiting plate is fixedly connected to the bottom end of the toothed plate. Both the front and rear ends of the limiting plate extend into the interior of the front and rear ends of the first gantry frame, and the outer surface is movably connected to the interior of the first gantry frame.

A pressure roller is movably connected between the interior of the two connecting blocks. The front and rear ends of the pressure roller extend to the exterior of the front and rear ends of the two connecting blocks, respectively.

[0006] As a preferred embodiment of this utility model, a driven wheel is movably connected between the left sides of the two long plates. A drive motor is fixedly installed on the right side of the front of the two long plates. The other end of the output shaft of the drive motor is fixedly sleeved with a rotating shaft located between the two long plates. The outer surface of the rotating shaft is movably connected to the interior of the two long plates.

[0007] In a preferred embodiment of this invention, a drive wheel located between the right sides of the two long plates is fixedly sleeved on the outer surface of the rotating shaft. The outer surface of the drive wheel is movably connected to the interior of the two long plates, and the drive wheel is connected to the driven wheel via a conveyor belt.

[0008] As a preferred embodiment of this utility model, table legs are fixedly connected to the four corners of the bottom of the two long boards, and a second gantry frame located on the left side of the first gantry frame is fixedly connected to the top of the two long boards. A stepper motor is fixedly installed in front of the top of the second gantry frame, and a round shaft is fixedly sleeved on the other end of the output shaft of the stepper motor.

[0009] As a preferred embodiment of this utility model, a long rod is fixedly sleeved on the outer surface of the circular shaft. Both ends of the long rod are hinged with movable rods. There are two movable rods. The other ends of the two movable rods are hinged with a moving plate located in the front-rear direction inside the top of the second gantry. There are two moving plates. The outer surfaces of the two moving plates are movably connected to the interior of the second gantry.

[0013] 1. This utility model is equipped with a servo motor, a rotating shaft, gears, and a toothed plate. When the operator starts the servo motor, it drives the rotating shaft to rotate synchronously with the gear. The gear then meshes with the toothed plate, thereby driving the toothed plate, the limiting plate, the spring, and the rectangular plate to move downward as a whole. This allows the pressure roller to guide tire sidewalls of different thicknesses. When the outer surface of the pressure roller contacts the top of the tire sidewall, according to the principle of force interaction, the pressure roller will push the rectangular plate upward as a whole through two connecting blocks. At this time, the spring is compressed, ultimately preventing the tire sidewall from getting stuck due to excessive pressure.

[0014] 2. This utility model, by setting a stepper motor, a round shaft, a long rod, and a movable rod, allows the operator to start the stepper motor, which drives the round shaft and the long rod to rotate synchronously. The long rod then drives two moving plates, two movable wheels, and two cutting blades to move in opposite directions through two movable rods. This allows the two cutting blades to cut the returned rubber on the sidewalls of tires of different sizes, thus providing convenience for the operator in actual use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6 As shown, this utility model provides an automatic tire sidewall return rubber splitting device, including two long plates 1. A first gantry frame 2 is fixedly connected to the right side of the top of each of the two long plates 1. A servo motor 3 is fixedly installed at the front of the top right side of the first gantry frame 2. A rotating shaft 4 is fixedly sleeved at the other end of the output shaft of the servo motor 3. A gear 5 is fixedly sleeved on the outer surface of the rotating shaft 4. A toothed plate 6 is movably connected inside the top of the first gantry frame 2. The top of the toothed plate 6 passes through the first gantry frame 2 and extends to the outside of the top of the first gantry frame 2, with its outer surface coinciding with the outer surface of the gear 5. The meshing connection is as follows: the bottom end of the toothed plate 6 is fixedly connected to the limiting plate 7. The front and rear ends of the limiting plate 7 extend into the interior of the front and rear ends of the first gantry 2 and the outer surface is movably connected to the interior of the first gantry 2. The front and rear sides of the bottom end of the limiting plate 7 are fixedly connected to the spring 8. The bottom end of the spring 8 is fixedly connected to the rectangular plate 9. The front and rear sides of the bottom end of the rectangular plate 9 are fixedly connected to the connecting block 11. There are two connecting blocks 11. The interior of the two connecting blocks 11 is movably connected to the pressure roller 10. The front and rear ends of the pressure roller 10 extend to the exterior of the front and rear ends of the two connecting blocks 11, respectively.

[0024] When the operator starts the servo motor 3, the rotating shaft 4 and gear 5 will rotate, causing the outer surface of gear 5 to mesh with the outer surface of toothed plate 6. This causes toothed plate 6 to drive the limiting plate 7, spring 8 and rectangular plate 9 to move downward as a whole, so that the outer surface of pressure roller 10 contacts the outer surface of tire sidewall, thereby guiding tire sidewalls of different thicknesses.

[0025] Among them, a driven wheel 12 is movably connected between the left sides of the two long plates 1. A drive motor 13 is fixedly installed on the right side of the front of the two long plates 1. The other end of the output shaft of the drive motor 13 is fixedly sleeved with a rotating shaft 14 located between the two long plates 1. The outer surface of the rotating shaft 14 is movably connected to the interior of the two long plates 1.

[0026] When the operator starts the drive motor 13, the rotating shaft 14 will rotate.

[0027] Among them, the outer surface of the rotating shaft 14 is fixedly sleeved with a driving wheel 15 located between the right sides of the two long plates 1. The outer surface of the driving wheel 15 is movably connected to the interior of the two long plates 1. The driving wheel 15 is connected to the driven wheel 12 through the conveyor belt 16.

[0028] When the rotating shaft 14 drives the driving wheel 15 to rotate, the driving wheel 15 will drive the driven wheel 12 to rotate via the conveyor belt 16.

[0029] Among them, table legs 17 are fixedly connected to the four corners of the bottom of the two long boards 1, and a second gantry 18 located on the left side of the first gantry 2 is fixedly connected to the top of the two long boards 1. A stepper motor 24 is fixedly installed in front of the top of the second gantry 18, and a round shaft 25 is fixedly sleeved on the other end of the output shaft of the stepper motor 24.

[0030] When the operator starts the stepper motor 24, the circular shaft 25 will rotate.

[0031] Among them, a long rod 26 is fixedly sleeved on the outer surface of the round shaft 25. Both ends of the long rod 26 are hinged with movable rods 19. There are two movable rods 19. The other end of each of the two movable rods 19 is hinged with a moving plate 23 located in the front-back direction inside the top of the second gantry frame 18. There are two moving plates 23. The outer surface of the two moving plates 23 is movably connected to the interior of the second gantry frame 18. The bottom ends of the two moving plates 23 pass through the second gantry frame 18 and extend to the outside of the top of the inner surface of the second gantry frame 18.

[0032] When the circular shaft 25 rotates, it will cause the long rod 26 to rotate as well.

[0033] Among them, two movable wheels 22 are movably installed inside the bottom end of the two second gantry frames 18. There are two movable wheels 22. The front and rear ends of the two movable wheels 22 extend to the outside of the front and rear ends of the two moving plates 23. Cutting blades 21 are fixedly connected to the opposite sides of the two movable wheels 22.

[0034] Due to the design of the two cutting blades 21, it is possible to perform the separation operation of the tire sidewall return rubber. The basic principle that the two cutting blades 21 achieve rotational cutting by driving two movable wheels 22 through two motors is common knowledge in the field and is not an improvement in this document. Therefore, the motors are not shown in the attached drawings, and the driving method will not be described in detail.

[0035] A cutting plate 20 is fixedly connected above the opposite surfaces of the two long plates 1, and the bottom end of the cutting plate 20 is movably connected to the top end of the conveyor belt 16.

[0036] Due to the design of the cutting plate 20, the two cutting blades 21 can be prevented from damaging the conveyor belt 16 when dividing the tire sidewall.

[0037] Working principle and usage process of this utility model:

[0038] First, the operator needs to adjust the height of the pressure roller 10 according to the thickness of the tire sidewall to be split. At this time, the operator starts the servo motor 3, which will cause the rotating shaft 4 and gear 5 to rotate, so that the outer surface of gear 5 meshes with the outer surface of toothed plate 6. This causes toothed plate 6 to drive the limiting plate 7, spring 8 and rectangular plate 9 to move downward as a whole, so that the outer surface of pressure roller 10 will contact the top of the tire sidewall. Since the forces are mutual, pressure roller 10 will push rectangular plate 9 upward as a whole through two connecting blocks 11. At this time, spring 8 will be in a compressed state. This operation can prevent the tire sidewall from getting stuck due to excessive pressure from pressure roller 10.

[0039] Finally, the operator operates the stepper motor 24 and the drive motor 13. The operation of the stepper motor 24 will cause the circular shaft 25 and the long rod 26 to rotate, which will cause the long rod 26 to drive the two moving plates 23 to move the two moving wheels 22 and the two cutting blades 21 in opposite directions through the two moving rods 19. This will enable the two cutting blades 21 to perform the cutting operation on the returned rubber on the tire sidewall of different widths. The operation of the drive motor 13 will cause the rotating shaft 14 to drive the driving wheel 15 to rotate. The rotation of the driving wheel 15 will drive the driven wheel 12 to rotate together through the conveyor belt 16, which will enable the tire sidewall located at the top of the conveyor belt 16 to move to the left and perform the cutting operation on the returned rubber on the tire sidewall.
