To make the technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

The embodiment of the invention discloses a tire finishing device 100 with a driving device inside, which is used for cleaning redundant materials such as burrs and the like on the inner surface and the outer surface of a tire. Referring to fig. 1, a tire retreading device 100 having a drive assembly therein includes a base plate 110, the base plate 110 supporting the various components of the overall tire retreading device. The base plate 110 is provided with a pad 120 for placing a tire, and in this embodiment, the tire can be laid on the pad 120, that is, the axis of the tire is perpendicular to the horizontal plane. The pad 120 is capable of rotating about its own central axis relative to the base plate 110 to facilitate tire rotation during dressing. Illustratively, the backing plate 120 is coupled to the base plate 110 via a slew bearing, or via a similar structure as the slew bearing.

The backing plate 120 is provided with a relief hole, and the relief hole may be circular, square or other irregular shapes, for example. After the tire is placed on the pad 120, the hole in the middle of the tire corresponds to the abdicating hole.

The dressing device of the embodiment comprises a driving device for driving the tire to rotate, so that the inner side and the outer side of the tire are cleaned and dressed during rotation of the tire. The drive means comprises a rotatable disc 145 which is movable radially and axially of the shim plate 120 to either abut the inner surface of the tyre sidewall or to move away from the inner surface of the tyre sidewall. Specifically, the rotating disc 145 is located in the relief hole of the pad plate 120 in the initial position, and in operation, the rotating disc 145 can move in the radial direction of the pad plate 120 to achieve the entrance into the tire or the exit from the tire. That is, at the time of the dressing work, the rotating disk 145 can enter the tire interior along the opening of the tire bead, and thereafter, the rotating disk 145 moves in the axial direction and comes into contact with the inner surface of the tire side wall. The inner surface of the tire side wall is the inner surface of the side wall that contacts the pad 120. The rotating disc 145 can rotate along the axis thereof, and when the rotating disc 145 rotates, the tire and the pad plate can be driven to rotate by friction force, so that the tire can be deburred or repaired at different positions.

Furthermore, a plurality of rotating disks 145 are provided, that is, at least two rotating disks 145 are provided in the abdicating holes of the base plate 120, and the rotating disks 145 are arranged at intervals, so that friction can be provided at different positions of the tire to drive the tire to rotate together. Preferably, the rotating disks 145 are evenly spaced, for example, when two rotating disks 145 are provided, they are spaced 180 degrees apart; when 4 rotating discs 145 are arranged, the rotating discs are arranged at intervals of 90 degrees to ensure that the tire is evenly stressed.

Further, when the rotating disc 145 is in close contact with the inner surface of the sidewall of the tire to be tested, a certain pressing force is formed on the tire by the pad plate 120, so that the rotating discs 145 arranged at intervals can also position the tire at the same time, and the tire is prevented from shifting or falling off in the rotating process. Each rotating disc 145 not only serves as a driving device to drive the tire to rotate, but also can play a role in positioning the tire, so that the stability of the tire during trimming can be improved, and the tire trimming effect is ensured.

With continued reference to fig. 1, the present embodiment includes trimming the tire surface with a cutter, the trimming of the tire surface including the trimming of the inner surface and/or the outer surface, i.e., only the inner surface or the outer surface of the tire may be trimmed, as well as both the inner surface and the outer surface of the tire. Illustratively, the cutter of the dressing apparatus of the present embodiment includes at least one first blade 143 and at least one second blade 153. The first blade 143 is disposed inside the pad 120, that is, the initial position of the first blade 143 is located in the relief hole of the pad 120, and the first blade 143 can move along the radial direction of the pad 120 to contact the inner surface of the tire for cleaning the inner surface of the tire. The second blade 153 is disposed outside the pad 120, and the second blade 153 can move along the radial direction of the pad 120 until the outer surface of the tire contacts with the outer surface of the tire, for cleaning the outer surface of the tire. That is, the embodiment of the present application can trim burrs on the surface of a trimmed tire and the outer surface of a tire by the first blade 143 and the second blade 153, respectively, and the trimming efficiency of the apparatus can be improved.

The technical scheme of this embodiment places the tire through setting up relative base pivoted backing plate 120 to set up a plurality of rolling discs 145 at the inboard interval of backing plate 120 abdication hole, first blade 143 and second blade 153 set up respectively in backing plate 120 inboard border and outside border, can clear up tire medial surface and lateral surface. After the tire to be trimmed is placed on the tie plate 120, each turn disc 145 is moved toward the tire (including first radially and then axially or first axially and then radially) to abut the inner surface of the tire sidewall. When the tire is trimmed, each rotating disc 145 rotates around the axis of the rotating disc 145, and as the rotating discs 145 are in contact and close contact with the inner surface of the tire side wall, the rotating discs 145 can drive the tire to rotate through friction force when rotating; meanwhile, since the base plate 120 can rotate relative to the base plate 110, the rotating discs 145 can drive the tire to rotate together with the base plate 120 relative to the base plate 110. The first blade 143 and the second blade 153 can clean the inner surface and the outer surface of the rotating tire at different positions, so that the effect of efficient finishing is achieved. In the process, the rotating disc 145 plays a dual role of driving and positioning the tire, the integration of functions increases the integration of the equipment, the structure of the equipment is simplified, and the cost of the equipment is reduced. And the tire can be fixed and kept stable when being trimmed, so that the trimming result is ensured.

When the tire is finished, each rotating disc 145 moves radially away from the tire, i.e., the rotating discs 145 move radially away from contact with the inner side of the tire, retract into the relief holes of the tie plates 120, facilitate removal of the tire after dressing, and facilitate placement of the next tire to be dressed.

Referring to fig. 1 and 2, the tire dressing apparatus of the present embodiment further includes a support plate 133, and the support plate 133 is located in the relief hole of the pad plate 120, that is, the diameter of the support plate 133 is smaller than the diameter of the relief hole of the pad plate 120. The rotating disc 145 and the first blade 143 are both disposed on the supporting plate 133, and the supporting plate 133 can move along an axial direction (shown as a Z direction in fig. 1) relative to the base plate 110 and the pad plate 120, so as to drive the rotating disc 145 and the first blade 143 to move along the axial direction to meet the requirements of tires with different specifications. And after the rotating disc 145 enters the tire, the support plate 133 drives the rotating disc 145 to move along the axial direction to be close to the inner surface of the tire sidewall. Illustratively, the bottom of the support plate 133 along the axial direction is provided with a first driving portion 132, the first driving portion 132 can drive the support plate 133 to move along the axial direction in the abdication hole of the pad plate, so as to drive each of the rotating disc 145 and the first blade 143 to move to adjust the relative position with the tire to be repaired in the axial direction, and ensure that the rotating disc 145 and the first blade 143 correspond to the opening of the tire bead, so that when the rotating disc 145 and the first blade 143 move along the radial direction, the tire can be entered into the interior of the tire through the opening of the tire bead.

Referring to fig. 2, the radial movement of the rotary disk 145 is driven by the second driving part 141, the second driving part 141 is disposed on the support plate 133, and an output end of the second driving part 141 is capable of extending and contracting in the radial direction and is connected with the driving disk 145 and/or the first blade 143 for driving the radial movement of the rotary disk 145 and the first blade 143. Understandably, the number of the second driving parts 141 corresponds to the number of the rotating disc 145 and the first blades 143. That is, the second driving part 141 is provided in plurality and is respectively connected to each of the rotating disks 145 and each of the first blades 143; one driving means may be connected to both the rotary disk 145 and the first blade 143. That is, one second driving part 141 drives the rotating disc 145 and the first blade 143 at the same time, and thus the number of second driving parts 141 can be reduced.

Illustratively, the number of the rotating disks 145 is the same as that of the first blades 143, a first mounting portion 142 is connected to an output end of each second driving portion 141, and a rotating disk 145 and a first blade 143 (shown in fig. 1) are disposed on the first mounting portion 142. Specifically, the first mounting portion 142 extends a set length in the axial direction, an upper end portion of the first mounting portion 142 is connected to an output end of the second driving portion 141, and the rotating disc 145 is connected to a lower end portion of the first mounting portion 142 in the axial direction, that is, the first mounting portion 142 extends in the axial direction and forms an L-shape with the second driving portion 141 extending in the radial direction. Because the size of the tire inside along the axial direction is larger than the distance of the tire bead opening along the axial direction, the first installation part 142 extends for a set length along the axial direction, so that the first installation part 142 can be ensured to drive the rotating disc 145 to move to the tire inside along the tire bead opening along the radial direction, and after the first installation part 142 can drive the rotating disc 145 to enter the tire, the rotating disc 145 can be contacted with the inner surface of the tire sidewall after moving for a smaller distance along the axial direction, so that the tire is driven to rotate from the inside.

Further, the rotating disc 145 is axially disposed below the first blade 143, so that the rotating disc 145 and the first blade 143 do not interfere with each other during operation, and the first blade 143 can cover the entire inner surface of the inner side of the tire in the axial direction, thereby ensuring complete finishing of the entire inner surface of the tire. In this embodiment, the rotating disc 145 and the first blade 143 are integrated with the first mounting portion 142, so that the structure of the apparatus can be simplified and the cost can be reduced.

Referring to fig. 3 and 4, a fourth driving portion 146 is disposed on the first mounting portion 142 corresponding to the rotating disc 145, and an output end of the fourth driving portion 146 is connected to the rotating disc 145 for driving the rotating disc 145 to rotate, so that the rotating disc 145 drives the tire to rotate through friction. Illustratively, the rotary disk 145 includes a coupling shaft, and the first mounting portion 142 is provided with a bearing, and the coupling shaft of the rotary disk 145 is coupled to the first mounting portion 142 through the bearing. The fourth driving part 146 is fixedly disposed on the first mounting part, and an output end thereof is connected to a connecting shaft of the rotating disk 145 to drive the rotating disk 145 to rotate. Illustratively, the fourth driving part 146 may be a small motor, a motor, or the like.

Further, the rotary disk 145 is coupled to the bottom of the first mounting portion 142, and the lowermost portion of the outer circumference of the rotary disk 145 protrudes from the lower end surface of the first mounting portion 142 so that the outer circumference of the rotary disk 145 can contact the tire. Specifically, the rotary disk 145 may be disposed on either one of two sides of the first mounting portion 142 in the radial direction, that is, the rotary disk may be disposed on an outer side of the first mounting portion 142 in the radial direction close to the tire (as shown in fig. 1 and 2) or may be disposed on an inner side of the tire in the radial direction far from the tire. Or in another embodiment, the bottom of the first mounting portion 142 is provided with an axially extending notch, and the rotating disc 145 is rotatably disposed in the notch. The present embodiment does not limit the specific connection manner of the rotating disc 145 and the first mounting portion 142.

In another embodiment, the rotary disc 145 and the first blade 143 may not be integrated into one component, such as the first mounting portion 142 of the present embodiment, but may be separately connected to driving devices, and the movement of the driving devices may be separately controlled by the respective driving devices.

Further, referring to fig. 3, the first driving part 132 and the support plate 133 are disposed through the base plate 110 to provide more axial space for the movement of the support plate 133. Illustratively, a through hole is formed in the base plate 110, a connection plate 131 extending downward in an axial direction by a certain distance is connected to a lower surface of the base plate 110 at a position corresponding to the through hole, and the first driving part 132 is disposed on the connection plate 131. With such an arrangement, the supporting plate 133 can be added to drive the rotating disc 145 and the first blade 143 to increase the adjustment distance in the axial direction, so that the positions of the rotating disc 145 and the first blade 143 relative to the tire can be adjusted in a wider range, and the tire repair device is suitable for tire repair of different specifications.

Further, when the trimming apparatus is not used or the tire trimming process is completed, after each second driving portion 141 drives each first mounting portion 142 to retract in the radial direction, the first mounting portion 142 is close to the outer side surface of the support plate 133, and the maximum radial profile dimension of the first mounting portion 142 and all components thereon is smaller than the inner diameter of the relief hole of the pad plate 120. That is, the rotary disk 145 and the first blade 143 can be retracted as the first mounting part 142 is moved in a radial direction, which is located in the receiving space between the support plate 133 and the pad plate 120. The accommodating space is limited in the radial direction from the yielding hole of the backing plate 120 to the through hole of the bottom plate 110; the receiving space extends axially from the surface of the shim plate 120 all the way down to the web 131. The first driving part 132 can drive the supporting plate 133 and the second driving part 141, the first mounting part 142, the rotating disc 145 and the first blade 143 thereon to move axially into the accommodating space, so that the equipment is convenient to store, and the damage of components is avoided.

Further, this embodiment further includes a supporting block 148 connected to the output end of the second driving portion 141 and slidably connected to the supporting plate 133 (correspondingly, a sliding slot connected to the supporting block 148 is disposed on the supporting plate 133), and the supporting block 148 is used for supporting the output end of the second driving portion 141, so as to prevent the second driving portion 141 from driving the first mounting portion 142 to move, and prevent the first mounting portion 142 from shaking, thereby ensuring stability during the tire trimming process.

Further, the first mounting portion 142 is provided with a first blade groove 1421 for receiving the first blade 143. The first mounting portion 142 is further provided with a third driving portion 144 connected to the first blade 143, and the third driving portion 144 can drive the first blade 143 to move out of the first blade groove 1421 in the radial direction or to be received in the first blade groove 1421. When it is necessary to trim the inner side surface of the tire, the third driving part 144 drives the first blade 143 to move out of the first blade groove 1421 and contact the tire to trim the inner surface of the tire, such as burr scraps. Before and after the tire is trimmed, the first blade 143 is moved by the third driving unit 144 to be received in the first blade groove 1421, thereby preventing an operator from being accidentally injured when the tire is placed and removed, and improving the safety of the operation.

Referring to fig. 1, 3 and 4, the second mounting portion 152 is disposed at an outer edge of the backing plate 120 for mounting the second blade 153. The fifth driving part 151 is disposed on the base plate 110, and an output end of the fifth driving part 151 is connected to the second mounting part 152, the fifth driving part 151 can drive the second mounting part 152 to move in a radial direction, and when the tire is placed, the fifth driving part 151 drives the second mounting part 152 to be close to the outer side of the tire to prepare for the dressing of the outer side of the tire. Further, the inner side of the second mounting portion 152 matches the shape of the outer side of the tire. That is, the side of the second mounting portion 152 that is close to the tire is arc-shaped, and the radian of the arc can be matched with the outer side of the tire, so that when the second mounting portion 152 is moved to a position close to the outer side of the tire, a limit is provided for the tire. Specifically, the radian of the side surface of the second mounting portion 152 is greater than or equal to the radian of the outer side surface of the tire, and after the second mounting portion 152 is moved in place, a certain gap is left between the second mounting portion 152 and the outer side surface of the tire, so that the tire can be guaranteed to rotate smoothly while the tire is limited. The second mounting portion 152 assists the rotating disc 145 in limiting the tire so that the tire is kept stable in position during the trimming process to ensure the trimming effect.

Further, a second blade groove 1521 is provided on the second mounting portion 152 for accommodating the second blade 153. The second mounting portion 152 is further provided with a sixth driving portion 154 connected to the second blade 153, and the sixth driving portion 154 can drive the second blade 153 to move out of the second blade slot 1521 in the radial direction or to be received in the second blade slot 1521. When the outer side of the tire needs to be trimmed, the sixth driving part 154 drives the second blade 153 to move out of the second blade groove 1521, and the second blade comes into contact with the outer side of the tire, so that the trimming of burrs and the like is performed. Before and after the tire is trimmed, the second blade 153 is moved by the sixth driving unit 154 to be received in the second blade groove 1521, thereby preventing the operator from being accidentally injured during the tire placement and removal.

In this embodiment, the second driving portion 141, the first mounting portion 142, a rotating disc 145, a first blade 143, a third driving portion 144 and a fourth driving assembly disposed on the first mounting portion 142 constitute the first cutter assembly 140. And a fifth driving part 151, a second mounting part 152, a second blade 153 and a sixth driving part 154, which are disposed at the outer edge of the backing plate 120, constitute a second cutter assembly 150. The first cutter assembly 140 and the second cutter assembly 150 may be provided in plural sets in a circumferential direction, and the first cutter assembly 140 and the second cutter assembly 150 may be provided correspondingly in a radial direction.

When cameras are arranged on the first mounting portions 142 and the second mounting portions 152, the control device can control the rotating disc 145 to drive the tire to rotate to the position of the first blade 143 or the second blade 153 closest to the burr for trimming, and therefore tire trimming efficiency is improved.

The flow of the technical scheme of the embodiment in use is described in detail below, so that the technical scheme of the embodiment can be understood in more detail:

in the initial state of the tire building apparatus of the present embodiment, each of the first blade 143 and the second blade 153 is located in the corresponding first blade groove 1421 and the second blade groove 1521, respectively, and the support plate 133, and the second driving portion 141, the first mounting portion 142, the rotating disk 145 and the first blade 143 thereon are all in the initial state and located in the accommodating space. After the tire to be trimmed is placed on the pad 120, the first driving portion 132 is activated to drive the support plate 133, i.e., the component thereon, to move upward in the axial direction, so that the first mounting portion 142 moves to a position corresponding to the opening of the tire bead. Each second drive portion 141 is then activated to drive each first mounting portion 142 radially toward the tire until the first mounting portion 142 moves inside the tire through the opening of the tire bead. The support plate 133 is then moved axially downward by the first driving portion 132 to bring each of the rotating disks 145 into close contact with the bottom of the inner side of the tire, to position the tire stably, and to prepare for driving the tire to rotate. The fifth driving part 151 drives the second mounting part 152 to move toward the tire in the radial direction until the second mounting part 152 approaches the outer side surface of the tire.

Next, the fourth driving part 146 drives the first blade 143 to extend out of the first to blade grooves 1421 to contact the inner side of the tire, and the sixth driving part 154 drives the second blade 153 to extend out of the second blade groove 1521 to contact the inner side of the tire. The fourth driving part 146 drives the rotating disc 145 to rotate, thereby rotating the tire and the pad plate 120 relative to the base plate 110, that is, relative to the first and second blades 143 and 153. During the rotation of the tire, the first blades 143 can trim burrs and sundries on the inner side of the tire, and the second blades 153 can trim burrs and sundries on the outer side of the tire. Meanwhile, the first camera 147 and the second camera 155 respectively detect the inner surface and the outer surface of the tire, and if an unfinished burr is found, the information is fed back to the control device, the control device controls the rotating disc 145 to rotate, so that the tire continues to rotate, and the unfinished part is rotated to the position of the first blade 143 or the second blade 153 for finishing. If the first blade 143 or the second blade 153 is spaced from the burr, the first blade 143 and/or the second blade 153 may be driven by the fourth driving part 146 and/or the sixth driving part 154 to move toward the tire by a certain distance, so that the trimming of the burr on the surface of the tire can be achieved.

After finishing, the fourth driving part 146 drives the first blade 143 to retract into the first to blade slot 1421, and the sixth driving part 154 drives the second blade 153 to retract into the second blade slot 1521. The first driving portion 132 drives the support plate 133 to move axially upward so that the first mounting portion 142 is positioned to correspond to the opening of the tire bead. The second driving portions 141 are activated to drive the first mounting portions 142 to move in the radial direction, so that the first mounting portions 142 are moved out of the tire from the opening of the tire bead. At the same time, the fifth driving part 151 drives the second mounting part 152 to move in the radial direction, so that the second mounting part 152 is spaced apart from the tire, and then the dressed tire is removed.

The technical scheme of the embodiment can ensure that the tire is kept stable in the trimming process, the inner side surface and the outer side surface of the tire can be efficiently trimmed, and the final trimming effect is ensured through the linkage of the first camera 147, the second camera 155 and the first blade 143 and the second blade 153.
