Description

Technical Field

[0001] The technology of the present invention relates to the field of automobile tires, and in particular to a tire bladder one-step molding machine. Background Art

[0002] The tire building machine's roll-back action is a key component of the tire building process. Currently used tire building machines can be categorized as bladder drum machines and mechanical drum machines, based on the roll-back method. The roll-back action of a bladder drum machine relies on the inflation of the bladder to radially expand the tire's sidewall and other components from a cylindrical shape and attach them to the tire's sidewall, forming the tire's sidewall. As a consumable tool in the tire manufacturing industry, the demand for bladders has grown with increasing tire production.

[0003] The production process of existing tire building machine bladders consists of three steps: rubber cylinder lamination, bladder assembly, and vulcanization. The rubber cylinder (film and carcass cord) lamination process is completed on a rotating drum. After completion, the plastic sheet (or PE paper) remains on the bottom of the film at the innermost part of the rubber cylinder. This process only completes the production of the cylindrical bladder body. The cylinder is then removed from the drum, folded in the outer chamber, and transferred to the bladder assembly drum, where it is assembled with the front end of the bladder. Finally, the bladder's external accessories are attached, followed by wrapping the bladder with water-proof cloth, completing the entire bladder lamination and assembly process.

[0004] However, the current capsule body rubber cylinder is transported between different workstations, which can easily lead to process deviations in positioning or stretching, as well as workpiece contamination. Summary of the Invention

[0046] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0047] like Figure 1 and Figure 2 As shown, the present invention provides a tire bladder one-shot forming machine, including a main drum device 100, an auxiliary drum device 200, a first forward and reverse packaging device 300, a second forward and reverse packaging device 400 and a rotating platform 500; the first forward and reverse packaging device 300 and the auxiliary drum device 200 are arranged on both sides of the rotating platform 500, and the first forward and reverse packaging device 300 and the auxiliary drum device 200 are respectively connected to the rotating platform 500, and the rotating platform 500 is configured to be able to rotate about a vertical direction so that the auxiliary drum device 200 rotates to the initial position of the first forward and reverse packaging device 300, the main drum device 100 is arranged on a side of the rotating platform 500 close to the first forward and reverse packaging device 300, and the second forward and reverse packaging device 400 is arranged on a side of the rotating platform 500 close to the auxiliary drum device 200; the first forward and reverse packaging device 300 can cooperate with the main drum device 100 to complete the forward and reverse packaging action of the main drum material, and the second forward and reverse packaging device 400 can cooperate with the auxiliary drum device 200 to complete the forward and reverse packaging action of the auxiliary drum material.

[0048] That is, the embodiment of the present invention provides a tire bladder one-time forming machine, which arranges the first front and back packaging device 300 and the auxiliary drum device 200 on both sides of the rotating platform 500 relative to each other. After completing the front and back packaging action, the auxiliary drum device 200 and the first front and back packaging device 300 can be swapped by rotating the rotating platform 500, thereby moving the auxiliary drum device 200 to dock with the main drum device 100, so that the rubber cylinders on the main drum device 100 and the auxiliary drum device 200 can be docked without moving, thereby completing the docking of the workpiece on the main drum device 100 and the workpiece on the auxiliary drum device 200. This solves the technical problems in the prior art that the rubber cylinder of the bladder main body is transferred to different workstations, which easily leads to process deviations in positioning or stretching, as well as workpiece contamination, thereby improving the production efficiency of tire bladders and ensuring the product qualification rate of tire bladders.

[0049] Specifically, the base of the rotating platform 500 is cylindrical. A motor and transmission gears can be mounted at the bottom of the rotating platform 500, allowing the rotating platform 500 to rotate about its axis. A transmission box is mounted above the rotating platform 500, housing a motor and a gear train. The two output shafts of the gear train are connected to the first front and back wrapping device 300 and the auxiliary drum device 200, respectively, mounted on the transmission box, driving both. The main drum device 100 and the second front and back wrapping device 400 are positioned on either side of the rotating platform 500, facilitating docking of the main drum device 100 with the auxiliary drum device 200 after the rotating platform 500 rotates. In this embodiment, the main drum device 100 is used to laminate the main film and the curtain fabric, forming the main curtain fabric rubber cylinder. The auxiliary drum device 200 is used to laminate the auxiliary drum film and the curtain fabric, forming the auxiliary curtain fabric rubber cylinder. The two front and back wrapping devices are used to sequentially perform front and back wrapping operations on the main curtain fabric rubber cylinder and the auxiliary drum curtain fabric rubber cylinder.

[0050] Furthermore, the main drum device 100 includes a main drum guide rail 110, a main drum chassis 120 and a main rotating drum 140; the main drum guide rail 110 is arranged along the extension direction of the main drum device 100 toward the rotating platform 500, the main drum chassis 120 is slidably set on the main drum guide rail 110, and the main rotating drum 140 is sleeved on the main drum shaft 130 set along the horizontal direction, and the main drum shaft 130 is transmission-connected to the main drum chassis 120 to drive the main rotating drum 140 to rotate around the main drum shaft 130.

[0051] Specifically, the main drum guide rail 110 is arranged on one side of the rotating platform 500 in the horizontal direction, and its extension direction is toward the first forward and reverse packaging device 300 on the rotating platform 500. The main drum housing 120 is slidably arranged on the main drum guide rail 110, and a motor and a transmission mechanism are provided in the main drum housing 120, and the transmission mechanism transmits and connects the motor to the main drum shaft 130. In this embodiment, the transmission mechanism can be set as a gear set to drive the main drum shaft 130 to rotate, and the main drum housing 120 uses a lead screw mechanism as a power to achieve sliding on the main drum guide rail 110. The main drum shaft 130 is key-connected with the main rotating drum 140, so that the main drum shaft 130 can drive the main rotating drum 140 to rotate. By setting the main drum housing 120 and the main rotating drum 140 to be slidably arranged on the main drum guide rail 110, the main rotating drum 140 can slide away from or close to the first forward and reverse packaging device 300. After the forward and reverse wrapping action is completed, the main rotating drum 140 can be slid away from the first forward and reverse wrapping device 300. When the rotating platform 500 rotates the auxiliary drum device 200 to the original position of the first forward and reverse wrapping device 300, the main rotating drum 140 is slid closer to the auxiliary drum device 200 to facilitate the docking of the two.

[0052] Preferably, the tire bladder one-time forming machine also includes a main drum feeding device 600, which includes a main drum feeding rack, a first material conveying mechanism and a first material diverting mechanism; the first material diverting mechanism is configured to divert the film and the cord, and the two ends of the first material conveying mechanism are respectively connected to the first material diverting mechanism and the main drum feeding rack. The first material conveying mechanism can convey the film and the cord to the main drum feeding rack, and the main drum feeding rack can be connected to the main rotating drum 140 to wind the film and the cord around the main rotating drum 140.

[0053] Specifically, the main drum feeding device 600 is arranged horizontally, perpendicular to the axis of the main rotating drum 140. It comprises a main drum feeding frame, a first material conveying mechanism, and a first material unwinding mechanism. In this embodiment, film and cord are pre-wound into large rolls and then placed in the unwinding station of the equipment. The unwinding mechanism is responsible for unwinding the large rolls of film and cord. The first material unwinding mechanism specifically comprises an unwinding support, a spool, a chuck, and a spool trolley. The unwinding support comprises an unwinding disc, a bearing seat, a bracket, a sprocket, and a bearing. The unwinding disc is mounted within the bearing seat via a rotating shaft to ensure stable unwinding. The spool is used to wind carcass material (such as cord or film). Both sides are fixed to the spool trolley via rotating shafts, allowing for free rotation. The chuck is mounted at the end of the spool's rotating shaft and docks with the guide support through positioning holes, ensuring precise positioning during material conveying. The spool is supported by brackets on both sides, and horizontal movement of the spool is achieved via slide rails or rollers, facilitating the replacement of material rolls or adjustment of the unwinding position. The first material unwinding mechanism in this embodiment also includes a winding mechanism. While unwinding the material, it simultaneously winds the PE paper or cloth covering it. After the material is used up, the remaining PE paper or cloth roll at the workstation is removed from the mechanism and replaced with a new material storage mechanism. In this embodiment, three first material unwinding mechanisms are provided to unwind different materials. The first material conveying mechanism, comprised of a frame, a driving roller, a driven roller, a drive motor, and a conveyor belt, conveys the film and curtain fabric unwound by the first material unwinding mechanism to the main drum feed rack. The main drum feed rack consists of a frame, a slewing cylinder, a drive motor, a driving roller, a driven roller, and a conveyor belt, all mounted on the frame. The frame includes a swingable material feed rack connected to the slewing cylinder. The swinging cylinder drives the material feed rack to swing, allowing it to dock with the main rotating drum 140 and deliver the curtain fabric and film fabric from the conveyor belt to the main rotating drum 140. When the feeding rack is not in use or someone is performing other operations on the main drum 140, the feeding rack is swung upward by the swing cylinder to make room for work.

[0054] Preferably, the main drum feeding device 600 also includes a main drum correcting mechanism; the main drum correcting mechanism is arranged on one side of the first material conveying mechanism, and the main drum correcting mechanism is provided with a correcting roller and a detection unit, and the detection unit is arranged toward the first material conveying mechanism to detect whether the film and the curtain are deviated, and two correcting rollers are arranged on both sides of the first material conveying mechanism, and the correcting rollers can abut against the film and the curtain to reset the film and the curtain.

[0055] Specifically, the main drum deflection correction mechanism features a mounting bracket, onto which both the detection unit and deflection correction rollers are mounted. The detection unit is configured as a photoelectric sensor, facing the first material conveyor mechanism, to detect material deflection in real time. The deflection correction rollers, made of aluminum alloy, rubber, or Teflon, support the material and assist in deflection correction, minimizing frictional damage. The two deflection correction rollers are symmetrically arranged in an "eight" shape, and they reposition the film and curtain fabric through tilting or translational motion.

[0056] like Figure 3 and Figure 4 As shown, further, the forward and reverse packaging device includes a finger-shaped piece 310, a reverse packaging capsule 320 and a forward and reverse packaging main shaft 330; the reverse packaging capsule 320 is surrounded by one end of the forward and reverse packaging main shaft 330, and the reverse packaging capsule 320 is configured to be inflatable. A number of finger-shaped pieces 310 are arranged around the forward and reverse packaging main shaft 330, and one end of the finger-shaped piece 310 is rotatably connected to the forward and reverse packaging main shaft 330 so that the other end of the finger-shaped piece 310 can open and close in a direction close to or away from the forward and reverse packaging main shaft 330. The end of the finger-shaped piece 310 connected to the forward and reverse packaging main shaft 330 is set on one side of the reverse packaging capsule 320, and the finger-shaped piece 310 extends toward the reverse packaging capsule 320.

[0057] Specifically, a telescopic mechanism is installed on the front and back wrapping spindle 330. The finger-shaped piece 310 is shaped like a rectangular strip, with one end connected to the telescopic mechanism. The telescopic mechanism drives the finger-shaped piece 310 to open and close relative to the front and back wrapping spindle 330, enabling the finger-shaped piece 310 to grasp the fabric. The finger-shaped piece 310 then gradually retracts and compacts the fabric, completing the initial bonding process. The back-wrapping capsule 320 is mounted on the front and back wrapping spindle 330 and is equipped with an inflation hole for inflation. After the front wrapping operation is completed, a filler strip is wrapped around the circumference of the retracted fabric tube and connected to form the core material of the capsule's clamping mechanism. The finger-shaped piece 310 is extended by the telescopic mechanism, spreading radially. The back-wrapping capsule 320 inflates, causing the finished fabric tube to fold upward. Once in contact with the fabric tube, the back-wrapping capsule 320 continues to inflate, pushing the tube upward to complete the back-wrapping operation.

[0058] Preferably, the forward and reverse wrapping device further includes a sleeve 340 , which is sleeved on the forward and reverse wrapping main shaft 330 , and the sleeve 340 can move axially along the forward and reverse wrapping main shaft 330 to push the finger-shaped piece 310 to rotate around the fixed end of the finger-shaped piece 310 .

[0059] Specifically, the retractable mechanism in the reverse-wrap device primarily comprises a sleeve 340 and an expander. The expander supports the finger-shaped pieces 310, allowing them to radially expand. The sleeve 340 is mounted on the reverse-wrap spindle 330 and is driven by a motor to move axially along the reverse-wrap spindle 330. When the finger-shaped pieces 310 need to retract, the sleeve 340 moves along the fixed end of the finger-shaped piece 310 toward the sliding end, pushing the conically arranged finger-shaped pieces 310 into a cylindrical arrangement, thereby cooperating with the reverse-wrap capsule 320 to complete the reverse-wrap operation.

[0060] Furthermore, the auxiliary drum device 200 includes an auxiliary drum chassis 210, an auxiliary drum shaft 220 and an auxiliary rotating drum 230; the auxiliary drum chassis 210 is arranged on the rotating platform 500, and the auxiliary rotating drum 230 is sleeved on the auxiliary drum shaft 220 arranged in the horizontal direction. The auxiliary drum shaft 220 is transmission-connected to the auxiliary drum chassis 210 to drive the auxiliary rotating drum 230 to rotate around the auxiliary drum shaft 220.

[0061] Specifically, the auxiliary drum housing 210 houses a motor and a transmission mechanism, which connects the motor to the auxiliary drum shaft 220. In this embodiment, the transmission mechanism can be configured as a gear train, thereby driving the rotation of the main drum shaft 130. The auxiliary drum shaft 220 is keyed to the auxiliary drum, enabling the shaft 220 to rotate the auxiliary drum, thereby cooperating with the auxiliary drum feeding device 700 to wind the auxiliary drum fabric into a rubber-coated drum.

[0062] Furthermore, the tire bladder one-time forming machine also includes an auxiliary drum feeding device 700, which includes an auxiliary drum feeding rack, a second material conveying mechanism and a second material deflecting mechanism; the second material deflecting mechanism is configured to deflect the film and the cord, and the two ends of the second material conveying mechanism are respectively connected to the second material deflecting mechanism and the auxiliary drum feeding rack. The second material conveying mechanism can convey the film and the cord to the auxiliary drum feeding rack, and the auxiliary drum feeding rack is connected to the auxiliary rotating drum 230 to wind the film and the cord around the auxiliary rotating drum 230.

[0063] Specifically, the auxiliary drum feeding device 700 is arranged in a horizontal direction perpendicular to the axis of the auxiliary drum 230, and includes an auxiliary drum feeding frame, a second material conveying mechanism, and a second material deflecting mechanism. The second material deflecting mechanism specifically includes a guide branch seat, an I-shaped wheel, a chuck, and an I-shaped wheel trolley. The guide branch seat includes a deflecting disk, a bearing seat, a bracket, a sprocket, and a bearing. The deflecting disk is installed in the bearing seat through a rotating shaft to ensure the stability of the deflecting action. The I-shaped wheel is used to wind the carcass material (such as cord, film, etc.). Both sides are fixed to the I-shaped wheel trolley through a rotating shaft to achieve free rotation. The chuck is installed at the end of the I-shaped wheel shaft and docks with the guide branch seat through a positioning hole to ensure accurate positioning during material transportation. The brackets on both sides support the I-shaped wheel, and the horizontal movement of the I-shaped wheel is achieved through a slide rail or roller, which is convenient for replacing the material roll or adjusting the deflecting position. The second material unwinding mechanism in this embodiment also includes a winding mechanism. While unwinding the material, it simultaneously winds up the PE paper or cloth covering it. After the material is used up, the remaining PE paper or cloth roll at the workstation is removed from the mechanism and replaced with a new material storage mechanism. In this embodiment, three second material unwinding mechanisms are provided to unwind different materials. The second material conveying mechanism, comprised of a frame, a driving roller, a driven roller, a drive motor, and a conveyor belt, conveys the film and curtain fabric unwound by the second material unwinding mechanism to the auxiliary drum feeder. The auxiliary drum feeder consists of a frame, a slewing cylinder, a drive motor, a driving roller, a driven roller, and a conveyor belt, all mounted on the frame. The frame includes a swingable material feeder connected to the slewing cylinder. The swinging cylinder drives the material feeder to swing, allowing it to dock with the auxiliary drum 230 and deliver the curtain fabric and film fabric from the conveyor belt to the auxiliary drum 230. When the feeding rack is not in use or the auxiliary drum 230 is being used by personnel for other operations, the feeding rack is swung upward by the swing cylinder to make room for work.

[0064] Preferably, the auxiliary drum feeding device 700 also includes an auxiliary drum correcting mechanism; the auxiliary drum correcting mechanism is arranged on one side of the second material conveying mechanism, and the auxiliary drum correcting mechanism is provided with a correcting roller and a detection unit, and the detection unit is arranged toward the first material conveying mechanism to detect whether the film and the curtain are deviated, and two correcting rollers are arranged on both sides of the first material conveying mechanism, and the correcting rollers can abut against the film and the curtain to reset the film and the curtain.

[0065] Specifically, the auxiliary drum deflection correction mechanism features a mounting bracket, onto which both the detection unit and deflection correction roller are mounted. The detection unit is configured as a photoelectric sensor, facing the secondary material conveyor mechanism, to detect material deflection in real time. The deflection correction rollers, made of aluminum alloy, rubber, or Teflon, support the material and assist in deflection correction, minimizing frictional damage. The two deflection correction rollers are symmetrically arranged in an "eight" shape, and they reposition the film and curtain fabric through tilting or translational motion.

[0066] Furthermore, the tire bladder primary molding machine further includes a transition inner mold; both ends of the transition inner mold can be detachably connected to the main drum 140 and the auxiliary drum 230 respectively.

[0067] Specifically, the transition inner mold is cylindrical in shape, with an outer diameter consistent with that of the main drum 140 and the auxiliary drum 230. It is made of metal, and its two ends can be connected to the main drum 140 and the auxiliary drum 230 respectively via bolts and connecting rods. After the two rubber-coated cylinders on the main drum device 100 and the auxiliary drum device 200 complete the forward and reverse wrapping movements, the main drum 140 can be slid and one end of the main drum 140 can be connected to the transition inner mold. Subsequently, the auxiliary drum device 200 is moved and connected to the transition inner mold via the connecting rod, completing the precise docking of the main drum 140 and the auxiliary drum 230, so as to facilitate the subsequent assembly of the two rubber-coated cylinders into the capsule main body cylinder.
