The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Referring to fig. 1 to 7, an embodiment of the present invention provides a belt bundle layer laminating drum, including a main shaft 1 and a plurality of drum tiles 2 arranged around the circumference of the main shaft 1, further including a plurality of supporting members 3, a pushing mechanism and an adjusting mechanism, where the plurality of supporting members 3 are respectively fixedly connected with the plurality of drum tiles 2, and the supporting members 3 can move radially relative to the main shaft 1; the pushing mechanism includes a first member 41 and a second member 42, the second member 42 being movable relative to the first member 41 in the axial direction of the main shaft 1 to push the support 3; the adjusting mechanism is sleeved outside the main shaft 1 and is in transmission connection with the first part 41, and the adjusting mechanism can drive the pushing mechanism to move along the axial direction of the main shaft 1.
When the tire blank forming machine is used, the pushing mechanism is driven to a proper position in the axial direction of the main shaft 1 through the adjusting mechanism according to the specification of a tire blank, and then the adjusting mechanism is kept to be inactive when a tire blank tread component with the same specification is formed. During the tread assembly shaping, the support 3 is driven by the pushing mechanism to move the support 3 radially outwards with respect to the spindle 1, so that the drum tiles 2 are in the expanded position; after the completion of the molding process, the gripping device grips the molded tread assembly, and then the pushing mechanism drives the support 3 to move radially inward with respect to the main shaft 1, so that the drum segments 2 move radially inward from the expanded position to the contracted position, so that the gripping device takes the tread assembly off the belt application drum. Through adjustment mechanism's setting, can adjust pushing mechanism in the ascending relative position of main shaft 1 axial, and then can set for the diameter size when each tile 2 in the belted layer laminating drum is in the extended position for belted layer laminating drum can adapt to the shaping of the tire child embryo tread subassembly of multiple specification. In addition, the adjusting mechanism is sleeved outside the main shaft 1, and the main shaft 1 is used for supporting, so that the transmission stability is ensured.
Specifically, as shown in fig. 1-2, the support 3 is disposed between the drum shoe 2 and the main shaft 1, and the drum shoe 2 is located radially outward of the support 3. In order to enable the plurality of supporting pieces 3 to only move radially relative to the main shaft 1 and open and close the plurality of drum tiles 2, a supporting plate 11 is fixedly arranged on the main shaft 1, a supporting block 12 is arranged on the supporting plate 11, a sliding groove is formed in the supporting block 12, a sliding rail 31 is arranged on the supporting pieces 3, and the sliding rail 31 is in sliding connection with the sliding groove. When the support member 3 slides along the radial direction of the main shaft 1, the slide rail 31 slides in the slide slot, so that the limiting and guiding effects are achieved.
The radial inner side of the support member 3 is fixedly provided with a guide rail 32, and the guide rail 32 and the axial direction of the spindle 1 form an included angle, that is, the guide rail 32 is obliquely arranged. The slide block 33 is slidably arranged on the guide rail 32, and the second component 42 is fixedly connected with the slide block 33. When the second part 42 moves along the axial direction of the main shaft 1, the second part 42 gives a force to the sliding block 33 along the axial direction of the main shaft 1, so that the sliding block 33 slides along the sliding rail 31, that is, the sliding block 33 and the sliding rail 31 perform relative motion, since the supporting member 3 can only move radially relative to the main shaft 1, the sliding rail 31 is subjected to the force of the sliding block 33 to push or pull the supporting member 3 to move radially relative to the main shaft 1, and further, the drum tile 2 is driven to open and close relative to the main shaft 1.
Since the guide rail 32 is disposed obliquely, the slide block 33 also moves obliquely with respect to the main shaft 1, and in order to connect the slide block 33 and the second member 42 firmly, the second member 42 has a tapered surface, and the slide block 33 is fixedly connected with the tapered surface. Of course, the sliding direction of the slider 33 is parallel to the tapered surface. That is, the second member 42 and the support member 3 are in a tapered fit, so that the linear motion of the second member 42 along the axial direction of the main shaft 1 can be converted into the linear motion of the support member 3 along the radial direction of the main shaft 1.
Further, the adjusting mechanism comprises a moving block 51, a connecting rod 52 and a driving assembly, the moving block 51 is in threaded connection with the outer surface of the main shaft 1, one end of the connecting rod 52 is connected with the first component 41, the other end of the connecting rod is connected with the moving block 51, and the driving assembly is in transmission connection with the moving block 51 so as to drive the moving block 51 to rotate and move along the axial direction of the main shaft 1. When the driving assembly drives the moving block 51 to rotate, because the moving block 51 is screwed with the main shaft 1, the moving block 51 rotates and moves linearly along the axial direction of the main shaft 1, the connecting rod 52 can be pushed to move linearly along the axial direction of the main shaft 1, and then the first component 41 can be pushed to move linearly along the axial direction of the main shaft 1.
Since the moving block 51 linearly moves along the axial direction of the main shaft 1 while rotating, and the connecting rod 52 linearly moves only along the axial direction of the main shaft 1, the end of the connecting rod 52 needs to be movably connected to the moving block 51 in order to prevent interference between the moving block 51 and the connecting rod 52. In the present embodiment, one end of the connecting rod 52 is provided with a mounting block 53, and the mounting block 53 is slidably connected with the moving block 51. Since the mounting block 53 can slide relative to the moving block 51, the moving block 51 smoothly pushes the connecting rod 52 to move axially. Specifically, a groove is formed in the moving block 51, the mounting block 53 is slidably disposed in the groove, and the mounting block 53 can slide around the axis of the spindle 1 relative to the moving block 51. When the moving block 51 moves while rotating, the mounting block 53 slides in the groove, so that the radial position of the mounting block 53 is unchanged, and the connecting rod 52 moves along the axial direction of the spindle 1 under the action of thrust.
An external thread is arranged on the outer surface of one end of the main shaft 1, the moving block 51 is annular, an internal thread is arranged inside the moving block 51, the internal thread is in threaded connection with the external thread, and the moving block 51 is rotated to enable the moving block 51 to move along the axial direction of the main shaft 1.
The driving assembly comprises a driving wheel 54, and the driving wheel 54 is fixedly connected with the moving block 51. The moving block 51 is driven to rotate by the rotation of the driving wheel 54, and the driving wheel 54 may be a manual wheel or a motor, which is not limited herein. The driving wheel 54 is also sleeved outside the main shaft 1, so that the structure is compact, the occupied space is reduced, and the driving wheel 54 can be operated outside the main shaft 1. Because the screw thread has the self-locking function, the accuracy of the rotation of the driving wheel 54 can be ensured.
Further, with the adjustment mechanism kept in operation, the adjustment mechanism also defines the relative position of the first member 41 in the axial direction of the spindle 1.
Preferably, the pushing mechanism is a cylinder assembly. The second member 42 is movable relative to the first member 41 in the axial direction of the spindle 1 under pneumatic action to drive the support 3 to move radially relative to the spindle 1 to control the opening and closing of the drum tiles 2. The first member 41 may be in contact with the spindle 1 and slidably connected thereto, or may be spaced from the spindle 1, which is not limited herein.
Because the pushing mechanism and the adjusting mechanism can move, the pushing mechanism is set to have an initial state and a target state, the adjusting mechanism has an initial position and a plurality of target positions, and the target positions of the adjusting mechanism are selected according to different specifications of the tire blank.
Referring to fig. 1, the adjustment mechanism is in an initial position, the push mechanism is in an initial state, the drum tiles 2 are in a retracted position, and the drum tiles 2 are in a position of a first retracted diameter. Referring to fig. 3, on the basis of fig. 1, the adjusting mechanism is stationary, that is, the adjusting mechanism is in the initial position, and the pushing mechanism is controlled to be in the target state, at this time, the first part 41 of the pushing mechanism is stationary, the second part 42 moves a distance along the axial direction of the main shaft 1, and the pushing slider 33 moves a distance along the guide rail 32, so that the support 3 and the drum tile 2 move a distance radially outward relative to the main shaft 1, and further the drum tile 2 is in the position of the first expanded diameter.
Referring to fig. 4, on the basis of fig. 1, in order to make the belt ply laminating drum adapt to the molding of a tire blank tread assembly of another size specification, first, the driving wheel 54 in the adjusting mechanism needs to be controlled to drive the moving block 51 to rotate, so that the connecting rod 52 moves axially along the main shaft 1, so that the adjusting mechanism is located at a first target position, and further, the pushing mechanism is driven to move axially along the main shaft 1 to a proper position, at this time, the pushing mechanism is still in an initial state, but because the whole pushing mechanism moves a distance along the axial direction of the main shaft 1, the sliding block 33 moves a distance along the guide rail 32, so as to push the support 3 and the drum tile 2 to move radially outwards for a certain distance relative to the main shaft 1, and further, the drum tile 2 is located at a. Wherein the second constricted diameter is greater than the first constricted diameter.
Referring to fig. 5, on the basis of fig. 4, the adjusting mechanism is kept stationary, and the pushing mechanism is controlled to switch from the initial state to the target state, at this time, the first part 41 in the pushing mechanism is stationary, and the second part 42 moves a distance along the axial direction of the main shaft 1 relative to the first part 41, so as to push the sliding block 33 to move a distance along the guide rail 32, so that the support 3 and the drum tile 2 move a distance radially outward relative to the main shaft 1, and further, the drum tile 2 is located at the position of the second expanded diameter.
Referring to fig. 6, the left half is shown the position of the tile 2 in the two states of the pushing mechanism when the adjustment mechanism is in the initial position; the right half shows the position of the tile 2 in two states of the pushing mechanism when the adjustment mechanism is in the first target position. Therefore, the distance that the drum tile 2 in the expanded position moves relative to the radial direction of the main shaft 1 is the sum of the distances that the adjusting mechanism and the pushing mechanism respectively drive the drum tile 2 to move.
When a tire blank and tread assembly with the same specification is formed, the adjusting mechanism is kept inactive, so that the position of the first part 41 of the pushing mechanism relative to the spindle 1 is unchanged, and only the second part 42 in the pushing mechanism needs to be controlled to move relative to the first part 41 along the axial direction of the spindle, so that the drum tile 2 can be controlled to move between the contraction position and the expansion position.
When the specification of the produced tire is changed, firstly, the adjusting mechanism is controlled to act, so that the pushing mechanism moves to a proper position along the axial direction of the main shaft 1; subsequently, the adjustment mechanism is kept inactive, so that the position of the first part 41 in the pushing mechanism with respect to the spindle 1 is unchanged; so that the belt application drum can adapt to the formation of a green tire tread component of another specification. During the molding process of the green tire tread assembly of the other specification, the second component 42 of the pushing mechanism is controlled to move axially along the spindle 1 relative to the first component 41, so that the drum tiles 2 can be controlled to move between the contraction position and the expansion position.
The above embodiments have been described only the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and is not departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
