The transfer ring 70 can transfer the bead on the bead pre-setting device 50 to the carcass drum 21, and can also transfer the processed carcass on the carcass drum 21 to the tread drum 31; a tire unloading clamp 80 that can take out the tire embryo 100 with the tread roll-formed on the tread drum 31 and put it into the tire chute 90.

[0045] The corresponding structures, functions and effects of the bead pre-setting device 50, the lower pressing device 60, the transfer ring 70 and the tire unloading clamp 80 will be introduced in detail respectively below.

[0046] Bead pre-setting device 50: As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the bead pre-setting device 50 of the present invention includes a bracket 51 fixed on the base 10. Two vertical plate slide rails 511 are fixed on the bracket 51 at left and right intervals. Vertical plate sliders 512 that can slide back and forth along the vertical plate slide rails 511 are installed on each vertical plate slide rail 511. The bottom surface of the adapter plate 521 at the bottom end of the vertical plate 52 is connected and fixed to the two vertical plate sliders 512, so that the vertical plate 52 can be slidably installed on the bracket 51 back and forth; below the vertical plate slide rails 511 on the bracket 51, a lead screw transmission device 53 for pulling the adapter plate 521 back and forth is installed. A bead pre-setting seat 54 is installed on the top of the vertical plate 52; the adapter plate 521 is provided with a traction hinge 531. The lead screw transmission device 53 actuates the traction hinge 531 to pull the adapter plate 521, so that the vertical plate 52 and the bead pre-setting seat 54 thereon slide back and forth on the bracket 51.

[0047] As Figure 3 and Figure 4As shown in the figure, the bead pre-setting seat 54 on the bead pre-setting device 50 of the present invention includes: on one side of the vertical plate 52, a triangular partition plate 542 fixed at intervals by three parallel slide bars 541 is provided. On the slide bars 541 on both sides of the middle partition plate 542, a circular plate 543 that can slide left and right along it is installed respectively. A first screw sleeve 544 is fixed at the center of each circular plate 543. A first lead screw 545 for the first screw sleeve 544 to move on is passed through the vertical plate 52 and the partition plate 542. A hand wheel 546 fixedly connected to the end of the first lead screw 545 is installed on the other side of the vertical plate 52; on each circular plate 543, three centering cylinders 547 are installed at intervals radially around the first screw sleeve 544. An arc-shaped tile 548 is installed at the end of the telescopic rod of each centering cylinder 547. A positioning groove 5481 for pre-setting the bead is provided on each arc-shaped tile 548. The bead pre-setting seat 54 is used in the following way. According to the carcass specifications to be produced, the first lead screw 545 is rotated by the hand wheel 546, and the two circular plates 543 are driven to move towards or away from each other through the first screw sleeve 544. When the interval between the positioning grooves 5481 of the arc-shaped tiles 548 on the left and right reaches the pre-set position, stop rotating the hand wheel 546, that is, set the pre-set interval of the two beads on the bead pre-setting seat 54. The worker hangs the two beads onto the positioning grooves 5481 of the arc-shaped tiles 548 on the left and right respectively, and then synchronously drives all the centering cylinders 547 on each circular plate 543 to drive all the arc-shaped tiles 548 to expand and support, so that the two beads can be synchronously centered at the center of the pre-set position to wait for the transfer ring 70 to clamp and transfer them to the carcass drum 21.

[0048] As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, a front position sensor A and a rear position sensor B for sensing the moving position of the bead pre-setting seat 54 are installed at intervals on the side of the bracket 51 of the present invention; when the bead pre-setting seat 54 moves forward on the bracket 51 to the position of the front position sensor A, the bead pre-setting seat 54 gives way to the left and right movement of the transfer ring 70; when the bead pre-setting seat 54 moves backward on the bracket 51 to the position of the rear position sensor B, the center of the bead pre-setting seat 54 is aligned with the central axis of the carcass drum 21, so that the beads on the bead pre-setting seat 54 are in a predetermined position where they can be clamped by the transfer ring 70.

[0049] Lower pressing device 60: As Figure 1 , Figure 2 , Figure 5 and Figure 6As shown in the figure, the lower pressing device 60 of the present invention includes a base 61 fixed on the base 10 below the tread drum 31. Two sets of tread wheel pressing devices 62 that can slide left and right are installed on the base 61. A servo motor 63 with a speed reducer 64 is fixed on the left side of the base 61. A second lead screw 65 for synchronously driving the two sets of tread wheel pressing devices 62 to move towards or away from each other is also installed on the top surface of the base 61; Each set of tread wheel pressing devices 62 includes: a base plate 621 slidably connected left and right on the base 61, a second nut 622 fixed in the middle of the base plate 621 and sleeved with the second lead screw 65, a column 623 vertically fixed on the top surface of the second nut 622, two wheel seats 626 equipped with rollers 627 are respectively installed on the front and rear sides of the column 623 through a moving pair in a liftable manner, and a pressing cylinder 628 is hinged on the base plate 621 on the front and rear sides of the column 623, and the cylinder rod 6281 of each pressing cylinder is hinged to the corresponding side wheel seat 626.

[0050] As Figure 5 and Figure 6 shown, the servo motor 63 drives the speed reducer 64 to drive the second lead screw 65 to rotate, so that the two second nuts 622 displace along the second lead screw 65, thereby driving the base plate 621 to slide left and right, realizing the movement of the two sets of tread wheel pressing devices 62 towards or away from each other on the base 61. In this way, the rollers 627 on the left and right sides can roll and press the tread between the tire side and the tire center. Through the four pressing cylinders 628, the linear lifting and rolling pressure of the front, rear, left, and right rollers 627 can be respectively controlled, improving the flexibility of the lower pressing device 60 for the tread fitting processing technology.

[0051] As Figure 5 and Figure 6 shown, parallel first guide rails 611 are installed on the base 61 at intervals front and back. First sliders 612 that are slidably connected to the first guide rails 611 are installed at the front and rear ends of the bottom surface of each base plate 621, thereby realizing the left and right sliding of the two sets of tread wheel pressing devices 62 on the base 61; The moving pair is a second slider 624 fixed on the side wall of the column 623 and a second guide rail 625 installed in the second slider 624 for lifting. The wheel seat 626 is fixed at the top end of the second guide rail 625; In this way, the front and rear rollers 627 on each set of tread wheel pressing devices 62 can be independently lifted linearly, with high precision in pressing the tread, making the wheel pressing, exhausting, and fitting of the left and right sets of tread wheel pressing devices 62 on the tread more flexible, and also avoiding the problems of poor precision caused by the hinge connection of the pressing wheels and easy air accumulation and bubble formation under the tread layer.

[0052] Transfer ring 70: As Figure 7 and Figure 1 、 Figure 2As shown in the figure, the transfer ring 70 of the present invention is installed on the gantry 40 and can slide left and right on the gantry 40. The transfer ring 70 includes two pairs of clamping arms 71 that can slide towards and away from each other in the front-rear direction. On each pair of clamping arms 71, there are oppositely arranged arc rings 72. An arc groove 721 is provided on the inner arc section of each arc ring 72. A number of magnets 73 for magnetically attracting the bead wire are installed at intervals in each arc groove 721. When the arc ring 72 approaches the bead wire, the magnets 73 can quickly attract the bead wire to the arc groove 721 for positioning by magnetic attraction; the left and right clamping arms 71 can adjust the spacing. As Figure 7 and Figure 4 shown, a symmetrically scaled scale 74 is installed in the left-right direction in front of the transfer ring 70. On the top of the left and right clamping arms 71, there is respectively fixed a pointer 75 that aligns with the arc groove 721 of the corresponding side clamping arm 71. Adjust the spacing of the left and right clamping arms 71 so that the two pointers 75 align with the corresponding scale 74 graduations, and set the spacing between the arc groove 721 on the left clamping arm 71 and the arc groove 721 on the right clamping arm 71, which is the spacing of the two bead wires pre-placed on the left and right arc tiles 548 on the bead wire pre-set seat 54. By the forward and backward displacement or the separation displacement of the front clamping arm 71 and the rear clamping arm 71, correspondingly, the front and rear arc rings 72 can clamp or release the corresponding bead wires.

[0053] As Figure 3 and Figure 7 shown, when adjusting the spacing between the positioning grooves 5481 of the left and right arc tiles 548 on the bead wire pre-set seat 54, it can be adjusted with reference to the scale 74 graduations on the transfer ring 70. When the bead wire pre-set seat 54 moves backward to the position of the rear position sensor B on the bracket 51, the center of the bead wire pre-set seat 54 is aligned with the central axis of the carcass drum 21, so that the bead wires on the bead wire pre-set seat 54 are in a predetermined position for the transfer ring 70 to clamp. When the cylinder rod of the centering cylinder 547 retracts to gather all the arc tiles 548, the bead wire pre-set seat 54 gives way to the front and rear arc rings 72, that is, the front and rear arc rings 72 can move horizontally left and right without being blocked by the bead wire pre-set seat 54 when it is in the position of the rear position sensor B.

[0054] As Figure 7 and Figure 1 、 Figure 2 shown, the left and right pairs of arc rings 72 on the transfer ring 70, in addition to the above, can clamp and transfer the bead wires pre-set on the bead wire pre-set seat 54 of the bead wire pre-set device 50 to the carcass buckle position processed by the carcass drum 21 of the carcass drum main machine 20, so that the carcass drum 21 can turn the bead wire back around the carcass lip through the reverse wrapping process action.

[0055] Tire unloading clamp 80: As Figure 1 、 Figure 2 、 Figure 8 and Figure 9As shown in the figure, the tire unloading clamp 80 of the present invention is slidably mounted on the gantry 40 in the left-right direction. It is located above the tread drum 31, and its sliding range is between the root of the transmission shaft of the tread drum 31 and directly above the tire slipping groove 90; the tire unloading clamp 80 of the present invention includes a suspended arm 81, a fixed hinge seat 82 provided at the bottom end of the suspended arm 81, two symmetrical arc-shaped clamps 83 hinged at the top end to the fixed hinge seat 82, and a slide rail assembly 85 is provided on the suspended arm 81 above the fixed hinge seat 82; the slide rail assembly 85 includes a fixed rail 851 fixed on the suspended arm 81, and a moving hinge seat 852 slidably connected to the fixed rail 851 and capable of sliding up and down; two connecting rods 84 for synchronously actuating the arc-shaped clamps 83 to expand or clamp are hinged to the moving hinge seat 852. Specifically, the top end of the arc-shaped clamp 83 is hinged to the fixed hinge seat 82 through a first hinge shaft 831, the lower end of the connecting rod 84 is hinged to the outside of the arc-shaped clamp 83 through a second hinge shaft 832, and the top ends of the two connecting rods 84 are jointly hinged to the moving hinge seat 852; a lifting cylinder 86 is also installed on the suspended arm 81 above the fixed rail 851, and the end of the cylinder rod 861 of the lifting cylinder is fixedly connected to the moving hinge seat 852.

[0056] As Figure 1 , Figure 2 , Figure 8 and Figure 9 shown in the figure, when the lower pressing device 60 performs tread fitting and rolling on the carcass on the tread drum 31, the arc-shaped clamps 83 of the tire unloading clamp 80 are located at the position of the main shaft on the left side of the tread drum 31 above the tread drum main body 30. When the tread drum 31 and the lower pressing device 60 cooperate to complete the tread fitting and rolling process, when the tread drum main body 30 stops working, the cylinder rod 861 of the lifting cylinder moves the moving hinge seat 852 to slide upward along the fixed rail 851. The moving hinge seat 852 synchronously pulls the two connecting rods 84, causing the two arc-shaped clamps 83 to rotate around the first hinge shaft 831 and open. Then, the tire unloading clamp 80 slides to the right on the gantry 40 onto the tread drum 31. The cylinder rod 861 of the lifting cylinder pushes the moving hinge seat 852 to slide downward along the fixed rail 851. The moving hinge seat 852 pushes the two connecting rods 84 to cause the two arc-shaped clamps 83 to rotate in the opposite direction around the first hinge shaft 831 to clamp the tire embryo 100 that has been rolled and shaped on the tread drum 31. Then, the tread drum 31 radially contracts, causing the tire embryo 100 to separate from the surface of the tread drum 31. Then, the tire unloading clamp 80 slides to the right on the gantry 40 to directly above the tire slipping groove 90, and then the lifting cylinder 86 actuates the moving hinge seat 852 to drive the connecting rods 84, causing the two arc-shaped clamps 83 to open and release the tire embryo 100, so that the tire embryo 100 falls into the tire slipping groove 90, and the tire embryo 100 automatically slides backward and transfers in the tire slipping groove 90.

[0057] A single transfer cylinder 86 is used to synchronously actuating two arc-shaped clamps 83 to expand and retract, which can effectively avoid the phenomenon of asynchronous movement of the two arc-shaped clamps 83. If the two arc-shaped clamps 83 are asynchronous, it will cause the opening angles of the two arc-shaped clamps 83 to be not large enough or the opening to be asymmetric, resulting in the embryo 100 on the tread drum 31 being unable to avoid the horizontal movement of the arc-shaped clamps 83. During the horizontal movement of the two flat arc-shaped clamps 83 with different opening synchronizations towards the tread drum 31, the embryo 100 will be horizontally scraped and stuck, which will cause damage to the tire unloading clamp 80 and the embryo 100.

[0058] The working principle and specific implementation actions of the present invention will be described below.

[0059] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 shown, the transfer ring 70 first moves leftward in the gantry 40 to directly above the tire chute 90, so that all the front and rear arc-shaped rings 72 of the transfer ring 70 move leftward to avoid the bead pre-setting seat 54. The lead screw drive device 53 actuates the traction hinge 531 to traction the transfer plate 521, so that the vertical plate 52 and the bead pre-setting seat 54 thereon slide forward on the bracket 51 to stop at the position of the front position sensor A. The worker hangs the two beads onto the positioning grooves 5481 of the arc-shaped tiles 548 on the left and right sides respectively, and then synchronously drives all the centering cylinders 547 on the respective circular plates 543 to drive all the arc-shaped tiles 548 to expand and support, so that the two beads can be synchronously centered at the center of the pre-set position. Then, the lead screw drive device 53 actuates the traction vertical plate 52 to move backward. When the bead pre-setting seat 54 slides forward on the bracket 51 to stop at the position of the rear position sensor B, the front and rear arc-shaped rings 72 of the transfer ring 70 move away from each other and open. The transfer ring 70 moves rightward in the gantry 40 to the position of the bead pre-setting seat 54, and then the front and rear arc-shaped rings 72 move towards each other to clamp, and the magnet 73 attracts the bead into the arc-shaped groove 721 to fix it; the transfer ring 70 completes the magnetic attraction and clamping work on the pre-set bead.

[0060] While the worker is hanging the wire ring on the wire ring presetting device 50 and the transfer ring 70 is clamping the magnetic wire ring, the carcass drum main unit 20 drives the carcass drum 21 to rotate, and the carcass feeding rack located behind the carcass drum 21 cooperates with the carcass drum 21 to bond the inner liner, 1# cord, 2# cord, and 3# cord. After bonding, the transfer ring 70 moves to the right along the gantry 40, and the wire ring presetting seat 54 slides forward on the bracket 51 to the front position sensor A position, making way for the left and right movement of the transfer ring 70, and the front and rear arc rings 72 buckle the left and right wire rings at the buckling position of the carcass drum 21 on the cord layer, and the cord is expanded and propped up and covers the wire ring through the pressure of the carcass drum 21, and then the front and rear arc rings 72 The wire ring is opened and released, and the transfer ring 70 moves to the left to exit the carcass drum 21. The folding wing rods on both sides of the carcass drum 21 move toward each other and support the cords on both sides of the carcass drum 21 to close and fit together in the middle of the carcass drum 21, so that the cord layer is wrapped around the wire ring; after the wrapping is completed, the front and rear arc rings 72 are opened and the transfer ring 70 moves to the right onto the carcass drum 21, and the front and rear arc rings 72 clamp the fitted and wrapped carcass, and the carcass drum 21 is deflated and contracted to separate from the carcass, and then the transfer ring 70 carries the carcass to slide to the left to the position of the tread drum 31 to center the carcass on the tread drum 31, and then the tread drum 31 expands to fix the carcass on the tread drum 31, and the transfer ring 70 moves out in the opposite direction to a position that cooperates with the wire ring preset seat 54.

[0061] Then as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the tread drum main unit 30 is started to drive the tread drum 31 to rotate, and the tread feeding rack located behind the tread drum 31 cooperates with the tread drum 31 to perform tread rubber bonding. After the bonding is completed, the lower pressing device 60 is started, and the reducer 64 is driven by the servo motor 63 to drive the second screw rod 65 to rotate, so that the two second screw sleeves 622 are displaced along the second screw rod 65, so as to drive the base plate 621 to slide left and right, so that the two sets of tread wheel pressing devices 62 can move toward or away from each other on the base 61, and through the four pressure cylinders 628, the linear lifting and rolling force of the front and rear rollers 627 on the left and right sides can be accurately controlled respectively, so that the front and rear rollers 627 on the left and right sides can roll and press the tread between the sidewall and the tire centerline. After the rolling is completed, the cylinder rods 6281 of the four pressure cylinders are retracted to separate all the rollers 627 from the tread. At this point, the process of bonding and pressing the tread on the tire body is completed to form the tire embryo 100.

[0062] Then as Figure 1 , Figure 2 , Figure 8 and Figure 9As shown, after the production of the tire embryo 100 is completed, the handling cylinder 86 on the tire unloading clamp 80 actuates the two connecting rods 84 synchronously. The two arc-shaped clamps 83 rotate and open synchronously. Then, the tire unloading clamp 80 slides to the right on the gantry 40, so that the two synchronously opened arc-shaped clamps 83 are aligned with the tire embryo 100. The cylinder rod 861 of the handling cylinder pushes the moving hinge seat 852 to slide downward along the fixed rail 851. The moving hinge seat 852 pushes the two connecting rods 84, causing the two arc-shaped clamps 83 to rotate reversely around the first hinge shaft 831 to clamp the tire embryo 100 that has been rolled and shaped on the tire surface drum 31. Then, the tire surface drum 31 contracts radially, so that the tire embryo 100 is separated from the surface of the tire surface drum 31. Then, the tire unloading clamp 80 slides to the right on the gantry 40 to directly above the tire chute 90, and then actuates the moving hinge seat 852 through the handling cylinder 86 to drive the connecting rod 84, causing the two arc-shaped clamps 83 to open and release the tire embryo 100, so that the tire embryo 100 falls into the tire chute 90, and the tire embryo 100 automatically slides backward and rotates in the tire chute 90. There is no need for manual unloading and handling of the tire embryo 100 on the tire surface drum 31 at all.

[0063] When manufacturing electric vehicle or motorcycle tires using the present invention, only one worker is required to place the bead on the bead preset seat 34. After the production of the tire embryo 100 is completed, the tire unloading clamp 80 removes it from the tire surface drum 31 and releases it into the tire chute 90 for automatic transfer. There is no need for manual tire unloading and handling, which greatly improves the production efficiency of electric vehicle or motorcycle tires, greatly reduces the production cost, and greatly reduces the manual labor intensity.

[0064] The above embodiments are only for illustrating the present invention, rather than limiting the present invention. Those of ordinary skill in the art can also make various transformations or changes without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and should be defined by each claim.
