[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0024] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0025] In order to solve the problems of a large number of tire tiles and redundant mechanisms in the prior art, the present application provides a tire unloading clamping device and a tire forming machine.

[0026] See also Figures 1 to 3 The tire unloading clamping device includes an annular frame 10 and at least two clamping structures 20. The clamping structures 20 are arranged on the annular frame 10 at intervals along the circumferential direction of the annular frame 10. The clamping structure 20 includes a base 30, a sliding member 40, a driving member 50 and a clamping member 60. The base 30 is arranged on the annular frame 10. Along the radial direction of the annular frame 10, the sliding member 40 is slidably connected to the base 30. The driving member 50 is arranged on the base 30 and drives the sliding member 40 to move relative to the base 30. The clamping member 60 is connected to the sliding member 40 and moves relative to the base 30 driven by the driving member 50 to clamp the tire barrel.

[0027] During the tire barrel unloading process, the driver 50 drives the slide 40 and the clamping member 60 toward the barrel, whereupon the multiple sets of clamping members 60 of the clamping structure 20 clamp and secure the barrel. The annular frame 10 then moves, transporting the barrel to the next working position. At this point, the driver 50 drives the clamping members 60 and the slide away from the barrel, freeing the clamping members 60 from their restraints, thus enabling the barrel to be unloaded. The provision of the clamping structure 20 facilitates the unloading of the barrel.

[0028] In the present application, the clamping structure 20 further includes a locking member 70 movably disposed on the base 30 and having a locking position for locking the sliding member 40 and an unlocking position for releasing the sliding member 40 .

[0029] After the clamping member 60 clamps the tire barrel, the locking member 70 switches to the locked position to prevent the tire barrel from falling out during the clamping process. To facilitate the movement of the clamping member 60, the driving member 50 is preferably a pneumatic cylinder, which drives the clamping member 60 and the sliding member 40 by extending or retracting the cylinder piston rod. After the locking member 70 locks the sliding member 40, it also protects the cylinder, preventing the clamping member 60 from being subjected to excessive force and causing the cylinder piston rod to retract.

[0030] In the present application, a guide block 31 is fixed on the base 30, and a guide rail 41 cooperating with the guide block 31 is provided on the sliding member 40. The guide rail 41 extends along the radial direction of the annular frame 10, and the locking member 70 is movably provided on the guide block 31 and can abut against the locking guide rail 41.

[0031] Specifically, the interaction between the guide block 31 and the guide rail 41 increases the stability of the sliding of the slider 40, thereby increasing the stability of the movement of the clamping member 60 and stably clamping the tire tube. After the piston rod of the cylinder is extended, the clamping member 60 contacts the tire tube for a few seconds, and then the locking member 70 switches to the locking position, thereby locking the slider 40. To facilitate the operation of the locking member 70, the locking member 70 is an electromagnetic control valve. When it is in the locked position, it is energized, and the magnetic force increases the resistance to sliding between the guide block 31 and the guide rail 41, thereby locking the sliding plate. When it is in the unlocked position, it is de-energized, and the resistance between the guide block 31 and the guide rail 41 is broken, allowing them to slide relative to each other.

[0032] See also Figure 2 and Figure 3 The clamping structure 20 also includes an adjusting seat 21, an adjusting rod 22 and an adjusting fastener 23. The adjusting seat 21 is arranged on the sliding member 40; the adjusting rod 22 is connected to the clamping member 60 and is arranged on the side of the clamping member 60 close to the adjusting seat 21, and along the radial direction of the annular frame 10, the adjusting rod 22 is slidably connected to the adjusting seat 21, and the adjusting fastener 23 is arranged on the adjusting seat 21, and the adjusting seat 21 fixes the adjusting rod 22 after sliding.

[0033] Specifically, the clamping member is connected to the adjustment seat 21 via an adjustment rod 22, which is in turn mounted on the slider 40. The relative sliding of the adjustment rod 22 and the adjustment seat 21 adjusts the distance between the clamping member 60 and the slider 40. When the size of the tire barrel changes, the position of the clamping member 60 may no longer be compatible with the changed barrel. By adjusting the distance between the clamping member 60 and the slider 40, the clamping member 60 can be adapted to different sizes of tire barrels, thereby expanding the range of use of the clamping assembly.

[0034] In the present application, the adjusting rod 22 is provided with a plurality of sockets for inserting the adjusting fasteners 23 . The adjusting fasteners 23 can be switched to engage with different sockets and change the relative position of the adjusting rod 22 and the adjusting seat 21 .

[0035] There are multiple adjustment seats 21 and adjustment rods 22 , and an adjustment seat 21 and an adjustment rod 22 are provided on both sides of the driving member 50 .

[0036] Specifically, the distance between the clamping member 60 and the slider 40 is changed by sliding the adjusting rod 22 within the adjusting seat 21. After sliding, the adjusting rod 22 is fixed by inserting the adjusting fastener 23 into the socket. Because the socket is fixed, the distance between the clamping member 60 and the slider 40 is also fixed when the adjusting rod 22 is inserted into a fixed socket. There are multiple sockets, and the distance between the clamping member 60 and the slider 40 varies when the adjusting rod 22 is inserted into different sockets. When the tire tube size varies, the adjusting rod 22 can be inserted into different sockets to accommodate tire tubes of different sizes. By providing multiple sockets and securing the adjusting rod 22 via the adjusting fastener 23, the distance between the clamping member 60 and the slider 40 can be easily adjusted, making it easier to accommodate tire tubes of different sizes. By providing multiple adjusting seats 21 and adjusting rods 22, the stability of the relative movement between the clamping plate and the slider 40 can be increased.

[0037] In the present application, the side of the clamping member 60 away from the driving member 50 is an arc surface. Since the tire barrel is round, the clamping member 60 is set to an arc shape, which can better fit the circumference of the tire barrel, thereby increasing the stability of clamping the tire barrel.

[0038] In the present application, there are three clamping structures 20, one of which is located directly above the centerline of the annular frame 10. In the present application, the clamping structures 20 are arranged at equal intervals along the axial direction of the annular frame 10.

[0039] The clamping structures 20 are arranged at equal intervals, so that each clamping structure 20 is evenly stressed, which provides a certain degree of protection for the clamping structures 20 and prevents a certain clamping structure 20 from being damaged due to continuous high pressure.

[0040] Preferably, when there are three clamping structures 20, one of the clamping structures 20 is located directly above the centerline of the annular frame 10, and the remaining two clamping structures 20 are symmetrically arranged on both sides of the clamping structure 20, with the spacing between each two adjacent clamping structures 20 being the same. This arrangement of the clamping structures 20 ensures that the clamping structures on both sides are evenly stressed, preventing damage to a particular clamping structure 20 due to continuous high pressure.

[0041] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0042] During the tire barrel unloading process, the driver 50 drives the sliding member 40 and the clamping member 60 toward the barrel, and the clamping members 60 of the multiple clamping structures 20 together clamp and secure the barrel. The annular frame 10 then moves to transport the barrel to the next working position. At this point, the driver 50 drives the clamping members 60 and the sliding frame away from the barrel, freeing the clamping members 60 from their restraints, thus completing the unloading process. The provision of the clamping structure 20 facilitates the unloading of the barrel.

[0043] 2. After the clamping member 60 clamps the tire tube, the locking member 70 switches to the locked position to prevent the tire tube from falling out during the clamping process. To facilitate the movement of the clamping member 60, the driving member 50 is preferably a pneumatic cylinder, which drives the clamping member 60 and the sliding member 40 by extending or retracting the cylinder piston rod. After the locking member 70 locks the sliding member 40, it also protects the cylinder, preventing the clamping member 60 from being subjected to excessive force and causing the cylinder piston rod to retract.

[0044] 3. The distance between the clamping member 60 and the sliding member 40 is changed by sliding the adjusting rod 22 within the adjusting seat 21. After sliding, the adjusting rod 22 is fixed by inserting the adjusting fastener 23 into the socket. Because the position of the socket is fixed, the distance between the clamping member 60 and the sliding member 40 is also fixed when the adjusting rod 22 is inserted into a fixed socket. There are multiple sockets. When the adjusting rod 22 is inserted into different sockets, the distance between the clamping member 60 and the sliding member 40 varies. When the tire barrel size varies, the adjusting rod 22 can be inserted into different sockets to accommodate tire barrels of different sizes. By providing multiple sockets and securing the adjusting rod 22 with the adjusting fastener 23, the distance between the clamping member 60 and the sliding member 40 can be easily adjusted, and the adjustment can be easily accommodated with tire barrels of different sizes.
