[0029] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0030] In order to solve the problem that the surface of the flipping drum tile in the prior art is seriously contaminated with materials, the invention provides a forming drum and a forming machine.

[0031] Please refer to Figures 1 to 6 , the forming drum of the present invention includes a spindle assembly 10, a support assembly 20 and a flipping assembly 30. The support assembly 20 is arranged around the spindle assembly 10 for supporting the apex. The flipping assembly 30 is arranged around the spindle assembly 10 and can rotate relative to the spindle assembly 10 to flip the apex.

[0032] The forming drum of the present invention is mainly applied to bonding the apex to the bead. During operation, the drive motor drives the spindle assembly 10 to rotate, so that the apex is wound around the support assembly 20 for one circle. The bead feeding mechanism drives the bead to move to one side of the forming drum. The flipping assembly 30 flips upwards along the axial direction of the spindle assembly 10 to flip the apex onto the bead. The flipping assembly 30 and the support assembly 20 of the present invention are separately arranged, which solves the problem that the apex is seriously contaminated with materials during flipping due to the use of the same structure for flipping and supporting at present.

[0033] The flipping assembly 30 of the present invention includes a plurality of flipping rods 31. The plurality of flipping rods 31 are arranged at intervals in the circumferential direction of the spindle assembly 10, surround the spindle assembly 10 for one circle and are evenly distributed. When the apex is wound, the flipping assembly 30 is located inside the apex. The hinge points of the flipping assembly 30 are located on one side of the apex. During flipping, the plurality of flipping rods 31 simultaneously flip outwards, thereby flipping the apex onto the bead. Among them, the flipping rod 31 rotates along a first preset direction, and the spindle assembly 10 rotates along a second preset direction. The first preset direction is perpendicular to the second preset direction.

[0034] In order to reduce the contact area between the support assembly 20 and the apex, and at the same time facilitate the uniform application of force to the apex during flipping, the support assembly 20 of the present invention includes a plurality of drum segments arranged at intervals in the circumferential direction of the main shaft assembly 10. Among them, the drum segments and the flipping rods 31 are arranged alternately in sequence, that is, a flipping rod 31 must be arranged between two adjacent drum segments, and there must be a drum segment between two adjacent flipping rods 31. According to one embodiment, the outer surfaces of the flipping rods 31 and the drum segments are flush and located on the same circumference.

[0035] To facilitate the smooth sliding down and attachment of the apex to the flipping assembly 30 during flipping, the flipping assembly 30 further includes a roller mechanism rotatably arranged on the flipping rods 31 for rolling connection with the apex. The roller mechanism includes two sets of rollers 32, and the two sets of rollers 32 are respectively arranged on both sides of the flipping rods 31. Among them, each set of rollers 32 includes a plurality of rollers 32, and the plurality of rollers 32 are arranged at intervals along the extending direction of the flipping rods 31. During flipping, the flipping rods 31 are lifted to drive the rollers 32 on both sides to lift the apex. When the flipping rods 31 rotate 90° and are perpendicular to the surface of the main shaft assembly 10, the apex slides along the rollers 32 onto the bead during the lifting process of the flipping rods 31. The rolling of the rollers 32 reduces the friction with the apex and at the same time facilitates the movement of the apex.

[0036] In this embodiment, the flipping assembly 30 can be movably arranged along the axial direction of the main shaft assembly 10, so as to adapt to the positions of different apexes, and at the same time can be adjusted according to the distance between the bead and the forming drum, and the hinge point position is changed, so that when the flipping assembly 30 flips, the apex can be reasonably attached to the bead. In this embodiment, by changing the position of the flipping assembly 30 in the axial direction of the main shaft assembly 10, the forming drum can adapt to different specifications of apexes and bead feeding mechanisms.

[0037] To realize the flipping of the flipping assembly 30, the forming drum of the present invention further includes a first sliding sleeve assembly 51, a first driving assembly 52 and a connecting rod assembly 53. The first sliding sleeve assembly 51 is sleeved on the main shaft assembly 10; the first driving assembly 52 is drivingly connected to the first sliding sleeve assembly 51 to drive the first sliding sleeve assembly 51 to move along the axial direction of the main shaft assembly 10; the connecting rod assembly 53 is rotatably arranged on the first sliding sleeve assembly 51; among them, the connecting rod assembly 53 includes a plurality of second connecting rod mechanisms 531, and the plurality of second connecting rod mechanisms 531 are arranged around the first sliding sleeve assembly 51 and are respectively rotatably connected to the first sliding sleeve assembly 51. The flipping assembly 30 includes a plurality of flipping rods 31, and the plurality of second connecting rod mechanisms 531 are arranged and hinged in one-to-one correspondence with the plurality of flipping rods 31. The first sliding sleeve assembly 51 moves to simultaneously drive each flipping rod 31 to rotate through the connecting rod assembly 53.

[0038] As Figure 1As shown, the linkage mechanism includes a first connecting rod and a second connecting rod. One end of the first connecting rod is rotatably connected to the flipping rod 31, and a chute is provided on the flipping rod 31. A slider protrusion is provided on the first connecting rod, and the slider protrusion is inserted into the chute. One end of the first connecting rod is movably inserted into the chute through the slider protrusion. The other end of the first connecting rod is rotatably connected to the slider structure 24. One end of the second connecting rod is rotatably connected to the middle position of the first connecting rod. The other end of the second connecting rod is rotatably connected to the first sliding sleeve assembly 51 driven by the first driving cylinder 521. During flipping, multiple first driving cylinders 521 in the first driving assembly 52 act simultaneously to drive the first sliding sleeve assembly 51 to move along the axial direction of the main shaft assembly 10. The movement of the first sliding sleeve assembly 51 drives the second connecting rod to move and pushes the first connecting rod to rotate and move, and the first connecting rod further pushes the flipping rod 31 to flip.

[0049] According to one embodiment, the molding machine includes a frame box 80, and each of the above-mentioned drive components is arranged inside the frame box 80. The above-mentioned molding drums are respectively arranged on both sides of the frame box 80. As Figure 1 shown, the support assembly 20 and the flipping assembly 30 of the molding drum on the left side are both in a horizontal state. In this state, the chafer can be wound. While the flipping assembly 30 of the molding drum on the right side is flipped up by 90°, perpendicular to the support assembly 20. This state is the state where the flipping assembly 30 flips the chafer onto the bead.

[0050] The molding drum further includes a first support seat assembly 23 and a first lead screw assembly 42. The first support seat assembly 23 is movably sleeved outside the main shaft assembly 10; the first lead screw assembly 42 is arranged inside the main shaft assembly 10; wherein, the flipping assembly 30 includes a plurality of flipping rods 31, and the plurality of flipping rods 31 are arranged on the first support seat assembly 23 at intervals along the circumferential direction of the main shaft assembly 10.

[0052] The first drive assembly 52 is adjustably arranged along the axial direction of the main shaft assembly 10. Wherein, the molding drum further includes a second support seat assembly and a second lead screw assembly 62.

The second support seat assembly is arranged in the second guiding groove section through a lead screw nut and is connected to the second lead screw assembly 62.

[0053] The molding drum of the present invention is fixed on a double-station rack through a connecting reducer flange. The bead feeding mechanism pushes the bead to the drum waiting position under the action of the ground rail. The triangular rubber material joint delivered by the chafer feeding rack is adsorbed by the drum tile suction cup assembly.

[0055] The forming drum of the present invention further includes a pressure roller device. The pressure roller extends out to compact the joint of the apex. After the pressure roller retracts, the air cylinder pushes the double-row roller turning plate on the turning assembly to turn 90 degrees and stand up, turning the triangular rubber material onto the bead. Since the turning plate is separated from the drum tile, by adjusting the hinge point position of the turning plate, the attachment trajectory of the bead and the apex is made more precise. After turning, small rollers are arranged in multiple rows and columns on the turning plate, so that the hot-bonded apex rubber material is attached to the bead in a rolling manner.

[0056] The bead feeding mechanism retracts, and under the action of the unloading device, the formed apex is lifted and unloaded to the completion area.

[0057] The diameter and horizontal position of the drum can be adjusted according to the specifications of the apex and the bead.

[0058] The characteristics of the present invention lie in adopting a new structure of the toothed drum tile support assembly and the double-row roller turning assembly, separating turning and support, reasonably adjusting the turning hinge point, making the attachment trajectory of the bead and the apex more precise, and improving the attachment quality. At the same time, the apex is attached to the steel ring in a rolling manner, avoiding the uneven speed of the highly viscous rubber material when sliding down, affecting the forming effect, and ensuring the product quality.

[0059] By adjusting the radial sizes of the support assembly and the turning assembly, different specifications of the apex or the bead can be matched.

[0060] The double-station frame of the forming machine improves the automation level and production efficiency of the apex.
