Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a drum-type capsule wrapping machine. Background Art

[0002] Bead Composition and Problems: The bead is a crucial component of the tire, consisting of a wire bead, bead apex, bead cover, and a ply cord wrap. During tire production, the bead bead and bead apex are typically connected by cord lamination. For small-diameter bead rings under 10 inches, the bead cover must be converted from a flat structure to a U-shaped structure due to its smaller diameter. During this process, the bead cover undergoes significant stretching, with smaller diameters leading to greater changes and resulting in significant buckling of the bead cover.

[0003] Furthermore, the tire cord lamination process relies primarily on manual operation, with no mechanical equipment capable of automated production. This results in low efficiency and is unable to meet the needs of large-scale production. Manual operation also struggles to ensure consistent quality from one lamination to the next, leading to issues such as folding and uneven lamination. Currently, there is no mature mechanical equipment in China capable of automating the lamination of small-diameter wire rings, leaving a technological gap. These issues not only impact tire production efficiency and quality but also hinder further development of the industry.

[0004] Therefore, the prior art needs to be further developed. Utility Model Content

[0023] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0024] According to the embodiment of the present invention, a drum-type capsule wrapping machine is provided. Figures 1 to 3 , including: a curtain fabric laminating device 1, the curtain fabric laminating device 1 includes a rotatably arranged forming drum 2, the forming drum 2 includes a plurality of tiles 21 that radially contract and expand under the drive of a tensioning and closing mechanism, the forming drum 2 is covered with a capsule 11, wherein the area of ​​the forming drum 2 covered with the capsule 11 is provided with a wire ring supporting mechanism 22 for supporting the wire ring 10; a positioning retaining ring 3, the positioning retaining ring 3 is hollow and has an avoidance groove 311, the positioning retaining ring 3 is arranged around the circumference of the capsule 11, and the positioning retaining ring 3 is used to stop the wire ring 10.

[0025] Specifically, when the forming drum 2 and the capsule 11 are in a contracted state, the cord 20 is fitted onto the capsule 11 in advance. By setting a positioning retaining ring 3, the wire ring 10 is stopped when the wire ring 10 is installed, and the wire ring 10 is positioned at the position of the wire ring support mechanism 22 in the contracted state. When the capsule 11 is inflated, the capsule 11 expands along both sides of the wire ring 10, driving the cord 20 to fit tightly with the wire ring 10 and the apex rubber, thereby automatically completing the cord fitting, avoiding stretching of the cord 20, making the cord distribution more even, and pressing more tightly, thereby improving the quality of the tire product and solving the technical problem of poor efficiency of tire wire ring wrapping in related technologies.

[0026] Preferably, the wire ring support mechanism 22 is located in the central area of ​​the bladder 11, so as to ensure that the curtain fabrics on both sides of the wire ring 10 are more evenly attached.

[0027] In the drum capsule wrapping machine of this embodiment, see Figure 1 The positioning retaining ring 3 is located on one side of the wire ring support mechanism 22 , and the positioning retaining ring 3 includes a positioning surface 312 located on the side of the positioning retaining ring 3 close to the wire ring support mechanism 22 , and the positioning surface 312 abuts against the side surface of the wire ring 10 .

[0028] Specifically, the radial extension direction of the positioning retaining ring 3 and the radial extension direction of the forming drum 2 are parallel to each other.

[0029] It should be noted that one end of the forming drum 2 is provided with a tensioning mechanism, a cylinder and other structures, and the forming drum 2 is provided with a feeding end at the end away from the tensioning mechanism and the cylinder. The operator puts the wire ring 10 on the capsule 11 through the feeding end. The positioning retaining ring 3 is located on the side of the wire ring support mechanism 22 away from the feeding end. The wire ring support mechanism 22 is blocked by the capsule 11. Therefore, when installing the wire ring 10, the wire ring 10 is stopped by the positioning retaining ring 3 so that it is accurately positioned at the wire ring support mechanism 22.

[0030] It can be understood that, by the positioning surface 312 abutting against the side surface of the wire ring 10 , the structure is simple and reliable, and the positioning of the wire ring 10 is effectively achieved.

[0031] In the drum capsule wrapping machine of this embodiment, see Figure 1 The positioning retaining ring 3 includes a support frame 313 and a base 314 fixedly connected to the support frame 313, and the support frame 313 is used to support the positioning retaining ring 3. Through the above arrangement, the support of the positioning retaining ring 3 is achieved.

[0032] In the drum capsule wrapping machine of this embodiment, see Figure 3The positioning retaining ring 3 includes a first positioning retaining ring 31 and a second positioning retaining ring 32 that are arranged opposite to each other. The first positioning retaining ring 31 and the second positioning retaining ring 32 are respectively arranged on both sides of the building drum 2. The first positioning retaining ring 31 and the second positioning retaining ring 32 are relatively movable along the radial direction of the building drum 2. Through the above arrangement, the first positioning retaining ring 31 and the second positioning retaining ring 32 can be respectively moved closer to or away from the building drum 2, thereby facilitating the loading and unloading of the wire ring 10.

[0033] In some embodiments, when the wire ring 10 needs to be installed, the first positioning retaining ring 31 and the second positioning retaining ring 32 can be respectively close to the forming drum 2, and the inner circles of the first positioning retaining ring 31 and the second positioning retaining ring 32 are respectively tightly attached to the capsule 11 in the contracted state. The wire ring 10 is placed on the capsule 11 so that the side surfaces of the wire ring 10 are respectively in contact with the first positioning retaining ring 31 and the second positioning retaining ring 32. As the capsule gradually inflates, the first positioning retaining ring 31 and the second positioning retaining ring 32 can be respectively moved away from the forming drum 2.

[0034] In the drum capsule wrapping machine of this embodiment, see Figure 1 The drum-type capsule encapsulation machine includes a first slide 33 and a second slide 34. The first slide 33 is connected to the first positioning retaining ring 31, and the second slide 34 is connected to the second positioning retaining ring 32. A slide rail 35 extends perpendicularly to the axial direction of the forming drum 2 and is slidably connected to the first slide 33 and the second slide 34. The slide and rail structure allows the first positioning retaining ring 31 and the second positioning retaining ring 32 to move closer to or further away from the forming drum 2, thereby completing the loading and unloading of the wire ring 10.

[0035] In some embodiments, a cylinder may be used to drive the first slide 33 or the second slide 34 to slide relative to the slide rail 35 .

[0036] In the drum capsule wrapping machine of this embodiment, see Figure 1 A magnetic component is installed on the positioning retaining ring 3, and the magnetic component is used to adsorb the wire ring 10 on the positioning surface 312.

[0037] It should be noted that since the inner diameter of the wire ring 10 is slightly larger than the outer diameter of the capsule 11 in the contracted state, there is a gap between the inner ring of the wire ring 10 and the capsule 11 in the contracted state, and the axis of the wire ring 10 cannot be collinear with the axis of the forming drum. By setting a magnetic part, the axis of the wire ring 10 can be collinear with the axis of the forming drum, so as to ensure that the wire ring 10 is positioned more accurately.

[0038] In the drum capsule wrapping machine of this embodiment, see Figure 1The drum-type capsule wrapping machine includes: a curtain unwinding mechanism 4, which includes a storage roller 41 for storing the curtain 20 and the padding cloth 30 and a padding cloth winding roller 42 for recovering the padding cloth 30. The curtain 20 is peeled off from the padding cloth 30 after passing through the peeling roller 43 of the curtain unwinding mechanism 4, and the padding cloth 30 is wound on the padding cloth winding roller 42 to form a padding cloth roll.

[0039] By providing the curtain unwinding mechanism 4 , the curtain 20 can be stored and output.

[0040] In some embodiments, the curtain unwinding mechanism 4 includes a driving component that is driven by a storage roller 41 and a pad cloth taking-up roller 42. The output shaft of the driving component is driven by the storage roller 41. The storage roller 41 and the pad cloth taking-up roller 42 are driven by a conveyor belt. A pneumatic damper is installed on the rotating shaft of the pad cloth taking-up roller 42 to keep a certain tension on the pad cloth.

[0041] In some embodiments, the storage roller 41 is provided with three sets of photoelectric switches for detecting the winding diameter of the storage roller 41. The three sets of photoelectric switches are arranged on the frame at intervals corresponding to the three winding diameters of low, medium and high respectively. The driving component can automatically start and stop the driving component according to the storage amount of the curtain, control the start and stop of the curtain guide mechanism, and ensure that the curtain is always in stock.

[0042] In the drum capsule wrapping machine of this embodiment, see Figure 1 The drum-type capsule encapsulating machine includes a curtain positioning device 5, which includes a rotatable conveyor roller 51 and positioning plates 52 arranged on both sides of the conveyor roller 51 along its axial direction. The sidewalls of the positioning plates 52 can abut against the curtain 20. The curtain 20 guided by the curtain guide mechanism 4 passes through the conveyor roller 51 and reaches the capsule 11. This arrangement ensures that the curtain 20 can accurately reach the capsule 11.

[0043] In some embodiments, the drum-type capsule wrapping machine can use manual cutting or an automatic cutting device to cut the curtain fabric 20 , and the cut curtain fabric is overlapped on the capsule 11 .

[0044] In the drum capsule wrapping machine of this embodiment, see Figure 3 The bead ring support mechanism 22 includes grooves formed on each tile 21. The grooves on each tile 21 form an annular support groove for accommodating the inner ring of the bead ring 10. By providing the annular support groove, when the forming drum 2 drives the bladder 11 to expand, the forming drum 2 stops expanding due to the resistance of the inner ring of the bead ring 10, so that the inner ring of the bead ring fits neatly into the annular support groove, thereby relatively fixing the bead ring 10.

[0045] In some embodiments, the folding mechanism also includes a main shaft, a piston, a connecting rod 23, a fixed seat, a cylinder and other structures. The fixed seat is fixedly connected to the chassis, the main shaft is rotatably connected to the fixed seat through a bearing, and the main shaft drives the forming drum 2 to rotate axially through a motor and other driving components. The cylinder drives the piston to move back and forth along the axial direction of the forming drum 2. The piston is connected to the connecting rod 23, and the connecting rod 23 drives the tile 21, thereby completing the expansion and contraction function of the tile 21.

[0046] The working process of the drum capsule wrapping machine in some embodiments is as follows:

[0047] 1. The diameter of the forming drum 2 is reduced, and the capsule 11 is also reduced accordingly. The head of the manually or automatically wrapped curtain is attached to the capsule 11. The forming drum 2 rotates 362 degrees, the curtain 20 is cut, and the joints are overlapped end to end to complete the curtain 20 attachment.

[0048] 2. After the curtain fabric is attached, drive the first slide 33 and the second slide 34 so that the inner circles of the first positioning retaining ring 31 and the second positioning retaining ring 32 are close to the capsule 11, insert the wire ring 10, and make a single side surface of the wire ring 10 abut against the positioning surface 312 to complete the positioning of the wire ring 10.

[0049] 3. The forming drum 2 drives the bladder 11 to expand. After the bladder 11 contacts the inner ring of the bead ring 10, the forming drum 2 stops expanding due to the resistance of the bead ring 10. The bladder 11 begins to be inflated, so that the bladder 11 expands along both sides of the bead ring 10, driving the cord 20 to fit tightly with the bead ring 10 and the apex. Since the cord 20 and the apex are both made of highly viscous rubber, the cord wrapping and the apex continue to adhere to each other after the bladder 11 is deflated, completing the U-shaped wrapping of the bead ring.

[0050] It should be noted that within one working cycle, the forming drum 2 rotates more than one circle, so that the curtain fabric 20 has an extra lap joint on the basis of completing one circle of bonding, thereby completing the end-to-end overlap of the curtain fabric. Preferably, the forming drum 2 rotates at an angle of 362 degrees, and the lap joint length is 15mm-30mm.

[0051] The drum-type capsule wrapping machine in this embodiment replaces traditional manual operations with mechanization, significantly reducing labor intensity, while making the cord distribution more uniform and the pressing tighter, greatly improving the quality and consistency of tire products.
