Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing, and more specifically, to a tire triangular rubber forming drum device and a tire bead forming system. Background Technology

[0002] Traditional triangular rubber forming drums typically use manual adjustment to control drum rotation and diameter. While this design meets basic operational requirements, it has several limitations, such as low efficiency due to manual adjustment, increased worker workload due to complex operation, high maintenance costs due to multiple drive devices, and safety hazards. Furthermore, drum flipping usually involves directly flipping the rubber sheet, causing the sheet surface to come into contact with the rubber material, which can easily lead to material adhesion, affecting the cleanliness and quality of subsequent operations. Utility Model Content

[0003] The main objective of this invention is to provide a tire triangular rubber forming drum device and a tire bead forming system to solve the problem of low automation in existing triangular rubber forming drum devices.

[0004] To achieve the above objectives, according to one aspect of the present invention, a tire triangular rubber forming drum device is provided, comprising: a support assembly, a main shaft, a spindle assembly, and a clutch. The main shaft is connected to the support assembly and is used to drive the support assembly to rotate. The spindle assembly is movably connected to the support assembly and is used to drive the support assembly to expand and contract. The main shaft is sleeved on the outside of the spindle assembly. The clutch is connected to the main shaft and has a closed state that is in transmission engagement with the spindle assembly and a disengaged state that is in transmission separation from the spindle assembly. When the clutch is in the closed state, the main shaft and the spindle assembly rotate synchronously and drive the support assembly to rotate as a whole. When the clutch is in the disengaged state, the spindle assembly rotates relative to the main shaft and drives the support assembly to expand and contract. The support assembly includes a flipping assembly for flipping the rubber material and a plurality of drum plates for supporting the rubber material. The flipping assembly is rotatably arranged relative to the drum plates and has a horizontal state extending along the axial direction of the main shaft and a flipped state inclined to the axial direction of the main shaft.

[0005] Furthermore, the tire triangular rubber forming drum device also includes a brake, which is intermittently connected to the main shaft. When the clutch is in the closed state, the brake is separated from the main shaft, and when the clutch is in the disengaged state, the brake is connected to the main shaft.

[0006] Furthermore, the tire triangular rubber forming drum device also includes a first drive assembly, which includes a transmission component and a first drive component. The transmission component is connected to the spindle assembly, and the clutch can be connected and disconnected from the transmission component. The transmission component and the spindle assembly are connected and disconnected through transmission. The first drive component is driven to connect with the transmission component. When the clutch is closed, the first drive component drives the transmission component to move and drives the main shaft and the spindle assembly to move synchronously.

[0007] Furthermore, the spindle assembly includes a turntable, and each drum plate can be movably disposed on the periphery of the turntable. When the spindle assembly rotates relative to the main shaft, the turntable drives each drum plate to move radially along the main shaft simultaneously.

[0008] Furthermore, the turntable has a circumferentially extending helical groove, and the support assembly includes a support rod connected to the drum plate. The support rod is radially movable and has a protrusion located within the helical groove. When the spindle assembly rotates, the protrusion moves along the extension direction of the groove.

[0009] Furthermore, the flipping assembly includes multiple flipping elements, which are arranged circumferentially along the main shaft and located between two adjacent drums.

[0010] Furthermore, the flipping component includes multiple rolling elements arranged along the axial direction of the main shaft, with the axis of the rolling elements perpendicular to the axis of the main shaft.

[0011] Furthermore, the tire triangular rubber support assembly also includes a flipping drive assembly, which includes: a slide plate, a connecting rod structure, and a second drive member. The slide plate is sleeved on the outside of the main shaft and can move along the axial direction of the main shaft. The two ends of the connecting rod structure are movably connected to the slide plate and the flipping assembly, respectively. When the slide plate moves along the axial direction of the main shaft, it drives the flipping assembly to switch between a horizontal state and a flipping state through the connecting rod structure. The second drive member is driven by the slide plate and drives the slide plate to move along the axial direction of the main shaft.

[0012] Furthermore, the tire triangular rubber forming drum device also includes multiple rubber material fixing components, each of which is located on the surface of the support assembly and is used to fix the head and tail of the rubber material.

[0013] According to another aspect of the present invention, a tire bead forming system is provided, including the above-described tire triangular rubber forming drum device.

[0014] By applying the technical solution of this utility model, the clutch and mandrel assembly are designed to both engage and disengage, allowing the mandrel assembly to rotate synchronously with the main shaft to drive the entire support assembly to rotate. This enables the rubber material to be wound around the support assembly. The mandrel assembly can also rotate relative to the main shaft, causing the support assembly to expand and contract. This allows the support assembly to accommodate rubber materials of different specifications, improving the flexibility and adaptability of the triangular rubber forming drum device. In this way, only one power source is needed to achieve the rotation and expansion / contraction of the support assembly, thereby realizing the winding of the rubber material around the support assembly and adapting to different specifications of rubber materials. This improves the automation level of the triangular rubber forming drum device, simplifies the structure, and enhances the convenience and flexibility of operation. Furthermore, by setting up a flipping component and a drum plate, the rubber material can not only be placed on the drum plate but also flipped onto other devices by the flipping component, further improving the automation level of the tire triangular rubber forming drum device.

[0027] To address the problem of low automation in existing triangular rubber forming drum devices, the main objective of this invention is to provide a tire triangular rubber forming drum device and a tire bead forming system, wherein the tire bead forming system includes the tire triangular rubber forming drum device described below.

[0028] like Figures 1 to 6 The tire triangular rubber forming drum device shown includes: a support assembly 10, a main shaft 20, a spindle assembly 30, and a clutch 40. The main shaft 20 is connected to the support assembly 10 and is used to drive the support assembly 10 to rotate. The spindle assembly 30 is movably connected to the support assembly 10 and is used to drive the support assembly 10 to expand and contract. The main shaft 20 is sleeved on the outside of the spindle assembly 30. The clutch 40 is connected to the main shaft 20 and has a closed state that is in transmission engagement with the spindle assembly 30 and a disengaged state that is in transmission disengagement from the spindle assembly 30. In the disengaged state, when the clutch 40 is in the closed state, the main shaft 20 and the spindle assembly 30 rotate synchronously and drive the support assembly 10 to rotate as a whole. When the clutch 40 is in the disengaged state, the spindle assembly 30 rotates relative to the main shaft 20 and drives the support assembly 10 to expand and contract. The support assembly 10 includes a flipping assembly 13 for flipping the rubber material and a plurality of drums 11 for supporting the rubber material. The flipping assembly 13 is flipped relative to the drums 11. The flipping assembly 13 has a horizontal state extending along the axial direction of the main shaft 20 and a flipped state inclined to the axial direction of the main shaft 20.

[0029] This embodiment, by configuring the clutch 40 and the mandrel assembly 30 to both engage and disengage, allows the mandrel assembly 30 to rotate synchronously with the main shaft 20, driving the support assembly 10 to rotate as a whole. This allows the rubber material to be wound around the support assembly 10. The mandrel assembly 30 can also rotate relative to the main shaft 20, causing the support assembly 10 to expand and contract. This allows the support assembly 10 to accommodate rubber materials of different specifications, improving the flexibility and adaptability of the triangular rubber forming drum device. In this way, only one power source is needed to achieve the rotation and expansion / contraction of the support assembly 10, thereby enabling the rubber material to be wound around the support assembly 10 and adapting to rubber materials of different specifications. This improves the automation level of the triangular rubber forming drum device, simplifies the structure, and enhances the convenience and flexibility of operation. Furthermore, by setting up the flipping assembly 13 and the drum plate 11, the rubber material can not only be placed on the drum plate 11, but can also be flipped onto other devices by the flipping assembly 13, further improving the automation level of the tire triangular rubber forming drum device.

[0030] In this embodiment, the tire triangular rubber forming drum device further includes a first drive assembly 50, which includes a transmission component 51 and a first drive component 52. The transmission component 51 is connected to the spindle assembly 30, and the clutch 40 can be connected to and separated from the transmission component 51. The transmission component 51 is engaged and disengaged from the spindle assembly 30 through transmission engagement and disengagement. The first drive component 52 is driven to connect with the transmission component 51. When the clutch 40 is in the closed state, the first drive component 52 drives the transmission component 51 to move and drives the main shaft 20 and the spindle assembly 30 to move synchronously.

[0031] Specifically, such as Figure 1 , Figure 2As shown, the transmission component 51 in this embodiment is configured as a synchronous belt structure. The transmission component 51 includes a driving pulley, a driven pulley, a synchronous belt, and a connector. The synchronous belt is sleeved on the outer periphery of the driving pulley and the driven pulley. The first driving component 52 is driven and connected to the driving pulley, and drives the synchronous belt to rotate via the driving pulley, thereby driving the driven pulley to rotate. The driven pulley is sleeved on the outer periphery of the spindle assembly 30 and can drive the driven pulley to rotate. The connector is also sleeved on the outer periphery of the spindle assembly 30 and connected to the driven pulley, thereby preventing the driven pulley from moving axially along the spindle assembly 30. In this embodiment, the transmission component 51 is located at the end of the spindle assembly 30 away from the support assembly 10, and the clutch 40 is sleeved at the end of the main shaft 20 away from the support assembly 10, thereby facilitating the transmission engagement and disengagement of the clutch 40 and the driven pulley. The clutch 40 and the driven pulley can be connected by a flange. For example, the clutch 40 can have a connecting flange extending along the axis of the main shaft 20 towards the driven pulley. The driven pulley can have a connecting hole along the axial direction of the main shaft 20. The connecting hole and the connecting flange can be connected by bolts. When the connecting hole and the connecting flange are connected, the clutch 40 is engaged with the spindle assembly 30. When the connecting hole and the connecting flange are separated, the clutch 40 is disengaged from the spindle assembly 30. Of course, the clutch 40 and the driven pulley can also adopt a concave-convex fit structure that automatically extends and retracts along the axial direction of the main shaft 20, as long as it can satisfy the engagement and disengagement of the clutch 40 and the spindle assembly 30. It should be noted that in this embodiment, the end of the spindle assembly 30 away from the support assembly 10 protrudes from the end of the main shaft 20 away from the support assembly 10, thereby providing space for the installation of the transmission component 51 at the end of the spindle assembly 30 away from the support assembly 10, and facilitating the engagement of the transmission component 51 and the clutch 40. Optionally, the first driving component 52 can be a servo motor, etc.

[0032] In this embodiment, the mandrel assembly 30 includes a turntable 31, and the support assembly 10 includes multiple drums 11. Each drum 11 is movably disposed on the periphery of the turntable 31. When the mandrel assembly 30 rotates relative to the main shaft 20, the turntable 31 drives each drum 11 to move simultaneously along the radial direction of the main shaft 20, thereby realizing the expansion and contraction of the support assembly 10 to accommodate different specifications of adhesive. Specifically, in this embodiment, the support assembly 10 is sleeved on the outer periphery of the main shaft 20, and the drums 11 are located on the side of the support assembly 10 away from the main shaft 20 to support the adhesive. Figure 5As shown, the drum plate 11 in this embodiment is plate-shaped, and the length direction of the drum plate 11 is along the axial direction of the main shaft 20. When the main shaft 20 rotates, the rubber material can be wrapped around the side of the drum plate 11 away from the central axis of the main shaft 20. When the support assembly 10 moves radially along the main shaft 20, the drum plate 11 will move away from or closer to the main shaft 20, thereby making the circumference of the surface of each drum plate 11 away from the main shaft 20 larger or smaller, thereby achieving support for rubber materials of different specifications.

[0033] In this embodiment, the turntable 31 has a circumferentially extending spiral groove, and the support assembly 10 includes a support rod 12 connected to the drum plate 11. The support rod 12 is radially movable and has a protrusion located within the spiral groove. When the spindle assembly 30 rotates, the protrusion moves along the extension direction of the groove, thereby driving the drum plate 11 to move radially along the turntable 31, thus realizing the expansion and contraction of the support assembly 10. Specifically, the turntable 31 has a spiral groove on the side near the support rod 12, and the spiral groove extends spirally along the circumference of the turntable 31, so that the support assembly 10 can match different specifications of adhesive when the protrusion is located at different positions in the spiral groove. The support rod 12 is configured as a rod extending radially along the turntable 31. The end of the support rod 12 near the spindle has a protrusion protruding towards the turntable 31. The end of the support rod 12 away from the spindle is connected to the drum plate 11. A fixing pin can be provided between the support rods 12. A disc-shaped fixing plate can be provided on the main shaft 20 near the end of the support rod 12. The fixing pin is connected to the fixing plate, thereby limiting the circumferential position of the support rod 12 relative to the main shaft 20, and thus limiting the circumferential position of the drum plate 11 relative to the main shaft 20. This ensures that when the drum plate 11 moves radially along the turntable 31, its circumferential position remains unchanged. Alternatively, depending on the actual situation, a spiral protrusion can be provided on the turntable 31, and a connecting recess can be provided on the support rod 12, with the spiral protrusion and the connecting recess engaging.

[0034] The drum plate 11 in this embodiment includes a first part and a second part. Both the first and second parts are plate-shaped with a serrated convex-concave structure. The support rod 12 is connected to the side of the drum plate 11 near the main shaft 20. The convex-concave structure is located on the side of the first and second parts that are close to each other, and the convex-concave structure includes protrusions and recesses. The protrusions and recesses are staggered along the axial direction of the main shaft 20. The protrusions and recesses of the first and second parts can be inserted into each other and moved away from each other. The connection between the support rod 12 and the drum plate 11 is located at the edge of the first and second parts that are far apart from each other. That is, the side of the first part that is far away from the second part is connected to one of the support rods 12, and the side of the second part that is far away from the first part is connected to the other support rod 12. When the turntable 31 drives each drum plate 11 to move simultaneously along the radial direction of the main shaft 20 away from the main shaft 20, the distance between the ends of each support rod 12 away from the main shaft 20 increases, and the diameter of the circumferential surface of the outer peripheral surface of each drum plate 11 increases. This causes the protrusion of the first part to exit from the recess of the second part, and the protrusion of the second part to exit from the recess of the first part. Thus, even if the diameter of the circumferential surface of the support assembly 10 increases, a gap along the axis of the main shaft 20 will not be formed between the first and second parts. This ensures that when the adhesive is wrapped around the surface of the drum plate 11 away from the main shaft 20, it is supported by the protrusions of the first and second parts and will not be suspended, thereby preventing deformation of the adhesive and ensuring its quality. When the turntable 31 drives each drum plate 11 to move simultaneously along the radial direction of the main shaft 20 towards the main shaft 20, the diameter of the circumferential surface of the outer peripheral surface of each drum plate 11 decreases, causing the protrusions and recesses of the first and second parts to interlock with each other to support smaller adhesive materials. In this way, the support component 10 can support rubber materials of various specifications, thereby improving the flexibility and adaptability of the tire triangular rubber forming drum device.

[0035] In this embodiment, the support assembly 10 further includes a flipping assembly 13 for flipping the adhesive material. The flipping assembly 13 is flipped relative to the drum plate 11. The flipping assembly 13 has a horizontal state extending along the axial direction of the main shaft 20 and a flipped state tilted in the axial direction of the main shaft 20, so that the adhesive material located on the drum plate 11 can be flipped onto the steel ring of other devices to realize the combination of adhesive material and steel ring.

[0036] In this embodiment, as Figure 4As shown, the flipping assembly 13 includes a plurality of flipping members 131, each of which is arranged circumferentially along the main shaft 20 and located between two adjacent drum plates 11. Specifically, in this embodiment, the flipping member 131 is configured as a plate extending axially along the main shaft 20. A strip groove extending axially along the main shaft 20 is provided between two adjacent drum plates 11. The strip groove is located at the end of the support rod 12 away from the main shaft 20. The flipping member 131 is disposed in the strip groove and does not protrude from the drum plate 11 along the axial direction of the support assembly 10, thereby ensuring that the adhesive is placed flat on the surface of the drum plate 11. When the flipping member 131 is flipped up, the end of the flipping member 131 away from the main shaft 20 moves in a direction away from the central axis of the main shaft 20, thereby flipping the adhesive on the drum plate 11 onto other devices.

[0037] Preferably, the flipping member 131 is provided with a plurality of rolling members, which are arranged along the axial direction of the main shaft 20 and the axis of the rolling members is perpendicular to the axis of the main shaft 20. This makes the friction between the rubber material and the flipping member 131 when the flipping member 131 flips the rubber material a rolling friction, thereby reducing the friction force, reducing the sticking of the material, and ensuring the quality of the rubber material.

[0038] In this embodiment, the tire triangular rubber support assembly 10 further includes a flipping drive assembly 60, which includes a slide plate 61, a connecting rod structure 62, and a second drive member 63. The slide plate 61 is sleeved on the outside of the main shaft 20 and can move along the axial direction of the main shaft 20. The two ends of the connecting rod structure 62 are movably connected to the slide plate 61 and the flipping assembly 13, respectively. When the slide plate 61 moves along the axial direction of the main shaft 20, the connecting rod structure 62 drives the flipping assembly 13 to switch between a horizontal state and a flipped state. The second drive member 63 is drivenly connected to the slide plate 61 and drives the slide plate 61 to move along the axial direction of the main shaft 20, thereby realizing the automatic flipping of the flipping assembly 13. Specifically, the connecting rod structure 62 in this embodiment includes a first connecting rod and a second connecting rod, which are movably connected. The flipping assembly 131 has an elongated groove extending along the axial direction of the main shaft 20. The end of the second connecting rod away from the slide plate 61 is disposed in the elongated groove and can move along the extension direction of the elongated groove. The end of the second link away from the flipping member 131 is hinged to the fixed plate of the main shaft 20, allowing the second link to rotate around the connection between the second link and the fixed plate. The end of the first link away from the slide plate 61 is movably connected to the second link, and the connection between the first and second links is located between the two ends of the second link. The first link is movably connected to the slide plate 61, so that when the slide plate 61 moves along the axial direction of the main shaft 20, it can push the first link to move, thereby driving the second link to move. The second link moves within the elongated groove and ultimately drives the flipping member 131 to flip. In this way, the angle at which the drum plate 11 flips can be controlled by the distance the slide plate 61 moves along the axial direction of the main shaft 20, thereby achieving flexible control of the angle at which the drum plate 11 flips, thus improving the flexibility of the tire triangular rubber support assembly 10 device in this embodiment. Moreover, the flipping of the drum plate 11 can be achieved using only a simple link structure 62 and a slide plate 61, which helps to simplify the structure of the tire triangular rubber support assembly 10 device and save costs.

[0039] In this embodiment, the slide 61 is disc-shaped, and each first connecting rod is hinged to the slide 61 along its circumference. For example... Figure 3 As shown, the second driving component 63 may include a structure comprising a motor, a ball screw assembly, a driving wheel, a tensioning wheel, and a driven wheel. Two or three sets of ball screw assemblies may be evenly distributed along the circumference of the main shaft 20; more sets may be provided depending on actual requirements. A tensioning wheel and a driven wheel are provided between two adjacent sets of ball screw assemblies. A tensioning wheel is also provided between the motor and the ball screw assembly. The ball screw assembly is connected to the driving wheel. Thus, the motor drives the ball screw assembly to move, thereby driving the axial movement of the slide plate 61. Alternatively, depending on the actual situation, the second driving component 63 may also be a cylinder, an electric cylinder, etc., which drives the slide plate 61 to move axially along the main shaft 20.

[0040] In this embodiment, the tire triangular rubber forming drum device further includes a brake 70. The brake 70 is intermittently connected to the main shaft 20. When the clutch 40 is in the closed state, the brake 70 is disengaged from the main shaft 20; when the clutch 40 is in the disengaged state, the brake 70 is connected to the main shaft 20. Thus, the brake 70 and the clutch 40 cooperate to ensure the flexibility and stability of the movement of the spindle assembly 30 and the main shaft 20. Specifically, the tire triangular rubber forming drum device in this embodiment also includes a frame. The brake 70 is mounted on the frame and is located on the outer periphery of the main shaft 20. A tensioning sleeve can be provided between the main shaft 20 and the brake 70 to ensure the stability of the connection between the brake 70 and the main shaft 20. When the brake 70 is disengaged from the main shaft 20 and the clutch 40 is engaged with the spindle assembly 30, the first drive member 52 can drive the spindle assembly 30 and the main shaft 20 to rotate synchronously. When the clutch 40 is disengaged from the spindle assembly 30, the first drive member 52 only drives the spindle assembly 30 to rotate, the main shaft 20 does not rotate, and the brake 70 is connected to the main shaft 20 to avoid the main shaft 20 being affected by the spindle assembly 30 and to ensure the stability of the main shaft 20.

[0041] In this embodiment, the tire triangular rubber forming drum device further includes multiple rubber material fixing members 80. Each rubber material fixing member 80 is located on the surface of the support assembly 10 and is used to fix the beginning and end of the rubber material. Figure 6 As shown, the adhesive fixing component 80 includes an adsorption component, which can be disposed on the surface of the drum plate 11 away from the main shaft 20. Multiple adsorption components can be disposed and arranged along the axial direction of the main shaft 20 to ensure reliable fixing of the adhesive, thereby facilitating the joint stitching of the adhesive and enhancing the quality of the adhesive joint. In this embodiment, two adhesive fixing components 80 are provided, one for fixing the head of the material and the other for fixing the tail of the material. Of course, depending on the actual situation, the adhesive fixing component 80 can be configured in other structural forms. For example, it can also be configured as a pressure plate, disposed on the side of the drum plate 11 away from the main shaft 20. The pressure plate can be fixed to the frame. When the adhesive is located on the drum plate 11, the pressure plate presses down on the adhesive to fix its position.

[0042] The operation process of the tire triangular rubber support assembly 10 in this embodiment is as follows: The rubber material, i.e., the triangular rubber strip cut to a fixed length, is wound around the outer surface of the drum plate 11 on the support assembly 10. The flipping part 131 is fixed on the slide plate 61 through the connecting rod structure 62. The ball screw assembly extends and pushes the slide plate 61 to move axially along the main shaft 20. The connecting rod structure 62 flips the rubber material wound on the drum plate 11 to a greater than 90° angle. The flipping angle can be adjusted as needed, and the material is flipped onto the steel rim for subsequent processes. Different lengths of rubber material can be wound by adjusting the distance between the drum plate 11 and the axis of the main shaft 20 through the turntable 31 and the support rod 12. To ensure that the rubber material can be wound on the drum plate 11, the rubber material fixing part 80 first fixes the head of the rubber material on the drum plate 11, and finally, another rubber material fixing part 80 adsorbs and fixes the tail of the material on the drum plate 11 so as to sew the head and tail of the material together.

[0043] It should be noted that "multiple" in the above embodiments refers to at least two.

[0044] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0045] 1. To solve the problem of low automation in existing triangular rubber molding drum devices;

[0046] 2. By setting the clutch and mandrel assembly to both engage and disengage, the mandrel assembly can rotate synchronously with the main shaft to drive the entire support assembly to rotate, so that the rubber material can be wound on the support assembly. The mandrel assembly can also rotate relative to the main shaft to drive the support assembly to expand and contract, so that the support assembly can accommodate rubber materials of different specifications, improving the flexibility and adaptability of the triangular rubber forming drum device.

[0047] 3. Only one power source is needed to achieve the rotation and expansion / contraction of the support components, thereby enabling the rubber compound to wrap around the support components and adapting to different specifications of rubber compound. This simplifies the structure of the triangular rubber molding drum device and improves the degree of automation.

[0048] Improve the ease and flexibility of operation.
