Description

Technical Field

[0001] The utility model relates to the field of automobiles, in particular to a tire molding roller device. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machinery. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects while driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance; at the same time, they are also required to have high wear resistance and flexibility resistance, as well as low rolling resistance and heat generation.

[0003] During the forming process of the tire embryo, the tire bead, wire layer, inner liner and other main components need to be combined together with the forming roller through the pressure roller mechanism to form a green embryo. After the pressure roller device presses the accessories, the two ends need to be curled inward. However, the existing pressure roller device cannot be directly curled when in use, and it is necessary to purchase a set of curling devices for use with it, which is costly and troublesome to operate. Utility Model Content

[0004] The utility model aims to solve the problem that the current tire roller device can only perform pressing but not curling. The utility model provides a tire molding roller device, which can directly perform curling after the tire is pressed, reducing the cost of purchasing a curling device separately, simplifying the production process of tire green sheets, and improving work efficiency.

[0005] In order to solve the above technical problems, the embodiment of the utility model discloses a tire forming roller device, comprising:

[0006] roof;

[0007] A bottom plate, the bottom plate and the top plate are spaced apart along a first direction, and the bottom plate is connected to the top plate in a manner of being movable along the first direction;

[0008] A forming roller, the forming roller and the bottom plate are spaced apart along the first direction and used for laying tire components, the forming roller comprising a first rotating shaft;

[0009] A curling device, the curling device comprising a first driving mechanism, a second driving mechanism and a side pressure roller, the side pressure roller comprising a second rotating shaft;

[0010] The first driving mechanism is used to drive the side pressure roller to move relative to the bottom plate along the second direction, so that the side pressure roller switches between a first position and a second position, in which at least a portion of the side pressure roller is located above the forming roller along the first direction in the first position, and in which the side pressure roller is not located above the forming roller in the second position;

[0011] The second driving mechanism is used to drive the side pressure roller to switch between a first state and a second state. In the first state, the second rotating shaft is parallel to the first rotating shaft. In the second state, along the second direction, the side pressure roller is located on one side of the forming roller. The second rotating shaft is perpendicular to the first rotating shaft. The first direction intersects with the second direction.

[0012] In the first position, the side pressure roller is in the first state, and in the second position, the side pressure roller is in the second state.

[0013] By adopting the above technical scheme, the bottom plate moves upward along the first direction to allow space to exist between the side pressure roller and the forming roller, so as to facilitate the feeding device to lay various tire components on the surface of the forming roller, such as tire rims, wire layers, inner liner layers and other components. After the feeding device has laid various tire components, the bottom plate moves downward along the first direction to allow the side pressure roller to press on the surface of the semi-finished product formed by various tire components. The first rotating shaft and the forming roller rotate continuously, driving the semi-finished product to rotate, so that the side pressure roller in contact with the semi-finished product also rotates synchronously. The side pressure roller cooperates with the rotation of the forming roller to apply pressure to the semi-finished product. The forming roller is heated to soften the rubber of the tire components, thereby bonding the various components together.

[0014] After heating for a period of time and bonding, the first driving mechanism drives the side pressure roller to move along the second direction away from the forming roller, and at the same time, the second driving mechanism drives the side pressure roller to change from the first state to the second state; that is, when the side pressure roller switches from the first position to the second position, the second driving mechanism drives the side pressure roller to change from the first state to the second state.

[0015] Specifically, in the first position, at least part of the side pressure roller is located above the forming roller, and along the first direction, at least part of the side pressure roller can contact the upper surface of the semi-finished product, cooperate with the rotation of the forming roller, apply pressure to the semi-finished product, and help to better bond the various tire components together. At this time, the side pressure roller is in a first state, that is, the first rotating axis is parallel to the second rotating axis, so that at least part of the side pressure roller located on the upper surface of the semi-finished product can be completely pressed on the upper surface of the semi-finished product to apply pressure thereto; in the second position, the side pressure roller is not located above the forming roller, that is, it does not contact the upper surface of the semi-finished product. At this time, the side pressure roller is in a second state, that is, the first rotating axis is perpendicular to the second rotating axis, and along the second direction, the side pressure roller is located on one side of the forming roller.

[0016] When the side pressure roller moves from the first position to the second position, it is simultaneously converted from the first state to the second state, that is, the side pressure roller moves along the second direction away from the forming roller while converting from being parallel to the forming roller to being perpendicular to the forming roller. The overall running trajectory is arc-shaped, that is, the semi-finished product part in contact with the forming roller also has the same arc-shaped running trajectory, thereby achieving the effect of curling one end of the semi-finished product inward.

[0017] When the curling work is completed, the first driving mechanism drives the side pressure roller to move along the second direction toward the forming roller, and at the same time, the second driving mechanism drives the side pressure roller to change from the second state to the first state; that is, when the side pressure roller switches from the second position to the first position, the second driving mechanism drives the side pressure roller to change from the second state to the first state, so that the side pressure roller returns to its original position, that is, at least part of the side pressure roller is located above the forming roller, and the first rotating shaft is parallel to the second rotating shaft.

[0018] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a tire forming roller device, wherein the first driving mechanism includes a first driving member, a moving member, a first connecting member and a second connecting member, wherein:

[0019] The moving member extends along the second direction;

[0020] The first connecting member extends along the first direction and is rotatably connected to the second connecting member, and the first connecting member is connected to a side of the moving member away from the top plate;

[0021] The second connecting member extends along the first direction, and the second connecting member is rotatably connected to the side pressure roller via the second rotating shaft;

[0022] One end of the second driving mechanism is rotatably connected to a side of the moving member away from the top plate, and the other end is rotatably connected to a side of the second connecting member away from the side pressure roller;

[0023] The first driving member is used to drive the movable member to move along the second direction, thereby driving the second connecting member to move along the second direction, so that the side pressure roller switches between the first position and the second position, and the second driving mechanism is used to drive the second connecting member to rotate relative to the first connecting member, so that the side pressure roller switches between the first state and the second state.

[0024] By adopting the above technical scheme, the first driving member drives the movable member to move along the second direction toward the direction away from the forming roller, and at the same time drives the first connecting member connected to the movable member to move synchronously, and the second connecting member connected to the first connecting member also moves synchronously, thereby driving the side pressure roller connected to the second connecting member to move along the second direction toward the direction away from the forming roller, so that the side pressure roller is converted from the first position to the second position; at the same time, the second driving mechanism drives the second connecting member rotatably connected to it to rotate relative to the first connecting member toward the forming roller, thereby driving the side pressure roller connected to the second connecting member to move with the second connecting member, so that the side pressure roller is converted from the first state to the second state. When the side pressure roller switches from the first position to the second position, the second driving mechanism drives the side pressure roller to convert from the first state to the second state.

[0025] Specifically, in the first position, at least part of the side pressure roller is located above the forming roller, and along the first direction, at least part of the side pressure roller can contact the upper surface of the semi-finished product, and cooperate with the rotation of the forming roller to apply pressure to the semi-finished product, so as to help the various tire components to be better bonded together. At this time, the side pressure roller is in the first state, that is, the first rotating axis is parallel to the second rotating axis, so that at least part of the side pressure roller located on the upper surface of the semi-finished product can be completely pressed on the upper surface of the semi-finished product to apply pressure thereto; in the second position, the side pressure roller is not located above the forming roller, that is, it does not contact the upper surface of the semi-finished product. At this time, the side pressure roller is in the second state, that is, the first rotating axis is perpendicular to the second rotating axis, and along the second direction, the side pressure roller is located on one side of the forming roller.

[0026] When the side pressure roller moves from the first position to the second position, it is simultaneously converted from the first state to the second state, that is, the side pressure roller moves along the second direction away from the forming roller while converting from being parallel to the forming roller to being perpendicular to the forming roller. The overall running trajectory is arc-shaped, that is, the semi-finished product part in contact with the forming roller also has the same arc-shaped running trajectory, thereby achieving the effect of curling one end of the semi-finished product inward.

[0027] When the curling work is completed, the first driving member drives the movable member to move along the second direction toward the forming roller, and at the same time drives the first connecting member connected to the movable member to move synchronously, and the second connecting member connected to the first connecting member also moves synchronously, thereby driving the side pressure roller connected to the second connecting member to move along the second direction toward the forming roller, so that the side pressure roller is converted from the second position to the first position; at the same time, the second driving mechanism drives the second connecting member rotatably connected to it to rotate relative to the first connecting member in the direction away from the forming roller, thereby driving the side pressure roller connected to the second connecting member to move with the second connecting member, so that the side pressure roller is converted from the second state to the first state. When the side pressure roller switches from the second position to the first position, the second driving mechanism drives the side pressure roller to convert from the second state to the first state, so that the forming roller restores its original position, that is, at least partially located above the forming roller, and the first rotating shaft is parallel to the second rotating shaft.

[0028] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a tire forming roller device, the bottom plate is provided with a sliding opening extending along the second direction, and the movable member is connected to the sliding opening in a manner of being movably connected along the sliding opening.

[0029] By adopting the above technical solution, the sliding opening extends along the second direction, and the moving member is connected to the sliding opening in a movable direction along the sliding opening, so that the first driving mechanism can drive the moving member to move along the second direction.

[0030] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a tire forming roller device, wherein a sliding rod is connected in the sliding opening, and the moving member is sleeved on the sliding rod.

[0031] By adopting the above technical solution, a sliding rod is connected in the sliding mouth, and the moving part is sleeved on the sliding rod, so that when the moving part moves along the sliding mouth, the sliding rod can limit the movement of the moving part.

[0032] According to another specific embodiment of the present utility model, the embodiment of the present utility model discloses a tire forming roller device, wherein the curling device comprises two, and the two curling devices are arranged at intervals along the second direction.

[0033] By adopting the above technical solution, two curling devices spaced apart along the second direction are provided, so that the curling operation can be performed on both ends of the semi-finished product.

[0034] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a tire forming roller device, which also includes a third driving unit, which is arranged on the top plate and passes through the top plate and is connected to the bottom plate to drive the bottom plate to move along the first direction.

[0035] By adopting the above technical solution, the third driving part penetrates the top plate and connects the bottom plate to connect the bottom plate and the top plate together, and can drive the bottom plate to move along the first direction, so that the bottom plate can drive the curling device connected to the sliding mouth on the bottom plate to move along the first direction.

[0036] Specifically, when the feeding device is feeding, the third driving unit can drive the bottom plate and the curling device to move upward along the first direction, so that there is space between the side pressure roller of the curling device and the forming roller, which is convenient for the feeding device to lay various tire components on the surface of the forming roller, such as tire rims, wire layers, inner liner layers and other components. After the feeding device has laid various tire components, the third driving unit can drive the bottom plate and the curling device to move downward along the first direction, so that the side pressure roller of the curling device is pressed on the surface of the semi-finished product formed by various tire components. The first rotating shaft and the forming roller rotate continuously, driving the semi-finished product to rotate, so that the side pressure roller in contact with the semi-finished product also rotates synchronously, and the side pressure roller cooperates with the rotation of the forming roller to apply pressure to the semi-finished product, and the forming roller is heated to soften the rubber of the tire components, thereby bonding the various components together.

[0037] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a tire forming roller device, which also includes a main pressure roller, which is arranged on a side of the bottom plate close to the forming roller, and the main pressure roller extends along the second direction and is located between the two curling devices. Along the first direction, the bottom of the main pressure roller and the bottom of the side pressure roller are in the same plane.

[0038] By adopting the above technical solution, the main pressure roller extends along the second direction, and its bottom is in the same plane as the bottom of the side pressure roller. With this design, when the side pressure roller cooperates with the rotation of the forming roller to apply pressure to the semi-finished product, the main pressure roller can apply pressure to the semi-finished product synchronously with the side pressure roller, so that each tire component is subjected to greater pressure and can be bonded together faster and better; at the same time, the main pressure roller is located between the two curling devices, so that the upper surface of the semi-finished product can be subjected to pressure and the upper surface can be evenly stressed.

[0039] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a tire molding roller device, and the molding roller is a roller body that can be heated and cooled.

[0040] By adopting the above technical scheme, the forming roller is a roller body that can be heated and cooled. Heating can soften the rubber of the tire components, thereby bonding the various components together. At the same time, the main pressure roller and the side pressure roller are cooperated to facilitate the pressing and connecting of the various tire components together, and then the curling device curls it. After the tire rim is formed on the green embryo, the forming roller can cool and shape it. One device can complete the forming of the tire rim without the aid of other curling devices and cooling devices, which facilitates the production of green embryos, saves costs, and simplifies the process.

[0041] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a tire forming roller device, along the second direction, both ends of the top plate are fixed with fixing plates, and a plurality of mounting holes are opened on the fixing plates.

[0042] The adoption of the technical solution makes it convenient for workers to fix and install the tire forming roller device using bolts and nuts.

[0053] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0054] refer to Figure 1The embodiment of the present application provides a tire forming roller device, comprising: a top plate 1, a bottom plate 2, a forming roller 3 and a crimping device 4. Exemplarily, the top plate 1, the bottom plate 2, and the forming roller 3 are sequentially moved along a first direction (i.e. Figure 1 The top plate 1 and the bottom plate 2 are both arranged in a rectangular shape, but are not limited thereto, and may also be a square, a pentagon, a triangle, etc.

[0055] For example, reference Figure 1 The bottom plate 2 is connected to the top plate 1 in a movable manner along a first direction, that is, the bottom plate 2 can move upward along the first direction (i.e. Figure 1 a direction as shown) and downward movement (i.e. Figure 1 b direction as shown), the forming roller 3 includes a first rotating shaft 30, which is used to lay various tire components, such as tire beads, steel wire layers, inner liner layers and other components, but not limited thereto.

[0056] For example, reference Figure 1 and Figure 2 The hemming device 4 includes a first driving mechanism 42, a second driving mechanism 43 and a side pressing roller 44, the side pressing roller 44 includes a second rotating shaft 440, and the first driving mechanism 42 is used to drive the side pressing roller 44 relative to the bottom plate 2 along the second direction (i.e. Figure 1 The side pressure roller 44 moves in the first direction (ie, the Y direction shown in FIG. 1 ) so as to switch between the first position and the second position. In the first position, the side pressure roller 44 moves in the first direction (ie, the Y direction shown in FIG. 1 ). Figure 1 X direction shown), at least a portion of the side pressure roller 44 is located above the forming roller 3 (reference Figure 1 In the second position, the side pressure roller 44 is not located above the forming roller 3 (not shown).

[0057] Exemplarily, the second driving mechanism 43 is used to drive the side pressure roller 44 to switch between a first state and a second state. In the first state, the second rotating shaft 440 is parallel to the first rotating shaft 30 (refer to Figure 1 In the state shown in the figure), in the second state, along the second direction, the side pressure roller 44 is located on one side of the forming roller 3, and the second rotating shaft 440 is perpendicular to the first rotating shaft 30; wherein, in the first position, the side pressure roller 44 is in the first state, and in the second position, the side pressure roller 44 is in the second state.

[0058] Exemplarily, the bottom plate 2 moves upward along a first direction (ie Figure 1 The bottom plate 2 moves downward along the first direction (i.e., the direction a shown in the figure) so that there is space between the side pressure roller 44 and the forming roller 3, which facilitates the feeding device to lay various tire components, such as tire beads, steel wire layers, inner liner layers, etc., on the surface of the forming roller 3. After the feeding device lays various tire components, the bottom plate 2 moves downward along the first direction (i.e., Figure 1The first rotating shaft 30 and the forming roller 3 rotate continuously, driving the semi-finished product to rotate, so that the side pressure roller 44 in contact with the semi-finished product also rotates synchronously, and the side pressure roller 44 cooperates with the rotation of the forming roller 3 to apply pressure to the semi-finished product, and the forming roller 3 is heated to soften the rubber of the tire components, thereby bonding the components together.

[0059] After heating for a period of time and bonding, the first driving mechanism 42 drives the side pressure roller 44 to move along the second direction away from the forming roller 3, and at the same time, the second driving mechanism 43 drives the side pressure roller 44 to change from the first state to the second state; that is, when the side pressure roller 44 switches from the first position to the second position, the second driving mechanism 43 drives the side pressure roller 44 to change from the first state to the second state.

[0060] Specifically, in the first position, at least a portion of the side pressure roller 44 is located above the forming roller 3, along the first direction (i.e. Figure 1 The side pressure roller 44 is located in the first position, that is, the first rotating shaft 30 is parallel to the second rotating shaft 440, so that at least part of the side pressure roller 44 located on the upper surface of the semi-finished product can be completely pressed on the upper surface of the semi-finished product to apply pressure thereto; in the second position, the side pressure roller 44 is not located above the molding roller 3, that is, it does not contact the upper surface of the semi-finished product. At this time, the side pressure roller 44 is in the second state, that is, the first rotating shaft 30 is perpendicular to the second rotating shaft 440, and along the second direction (that is, Figure 1 The side pressure roller 44 is located on one side of the forming roller 3 (in the Y direction shown).

[0061] When the side pressure roller 44 moves from the first position to the second position, it is simultaneously converted from the first state to the second state, that is, the side pressure roller 44 moves along the second direction away from the forming roller 3, and at the same time converts from being parallel to the forming roller 3 to being perpendicular to the forming roller 3. The overall running trajectory is arc-shaped, that is, the semi-finished product part in contact with the forming roller 3 also has the same arc-shaped running trajectory, thereby achieving the effect of curling one end of the semi-finished product inward.

[0062] When the curling work is completed, the first driving mechanism 42 drives the side pressure roller 44 to move along the second direction toward the forming roller 3, and at the same time, the second driving mechanism 43 drives the side pressure roller 44 to change from the second state to the first state; that is, when the side pressure roller 44 switches from the second position to the first position, the second driving mechanism 43 drives the side pressure roller 44 to change from the second state to the first state, so that the side pressure roller 44 returns to its original position, that is, at least part of the side pressure roller 44 is located above the forming roller 3, and the first rotating shaft 30 is parallel to the second rotating shaft 440.

[0063] The following is combined with Figure 1 To Attachment Figure 3 The specific structure of the curling device 4 is introduced in detail.

[0064] Exemplarily, the hemming device 4 includes two hemming devices 4, and the two hemming devices 4 are arranged along the second direction (ie Figure 1 The two hemming devices 4 are arranged at intervals along the Y direction shown in the figure. For the convenience of description, the one on the left is called the first hemming device 40, and the one on the right is called the second hemming device 41. By setting two hemming devices 4 spaced along the second direction, the hemming operation can be performed on both the left and right ends of the semi-finished product. The two hemming devices 4 have the same structure, so the first hemming device 40 on the left is taken as an example for the following description. For example, refer to Figure 1 and Figure 2 The bottom plate 2 is provided with a Figure 1 The two sliding openings 20 extend in the Y direction (shown in the figure), and the extension length of the two sliding openings 20 enables the moving member 421 described later to drive the side pressure roller 44 to be in the second state. The two sliding openings 20 are arranged between the output shafts of the two second cylinders 50 described later, and along the second direction (i.e. Figure 1 The two slides 20 are arranged at intervals in the Y direction as shown, and both slides 20 are rectangular in shape. The slides 20 are designed to allow the bottom of the moving member 421 described later to slide smoothly through the bottom of the bottom plate 2.

[0065] For example, two slide bars 21 are connected to the two slide openings 20, and the two slide bars 21 are connected to the two slide openings 20 along the third direction (i.e. Figure 1 The two movable members 421 are arranged at intervals (in the Z direction shown in the figure) and are respectively slidably connected with the corresponding movable members 421 described later, so that the movable members 421 are connected to the sliding mouth 20 in a manner that they can move along the sliding mouth 20; at the same time, when the movable member 421 moves along the sliding mouth 20, the sliding rod 21 can limit its movement.

[0066] It should be noted that the embodiment of the present application does not limit the number of sliding openings 20, as long as it is consistent with the number of curling devices 4. Similarly, the embodiment of the present application does not limit the shape of the sliding openings 20, as long as it can accommodate and limit the moving parts 421 described later. The embodiment of the present application does not limit the number of sliding rods 21, and it can also be one, three, or other numbers.

[0067] The first direction (i.e. Figure 1 The X direction shown), the second direction (i.e. Figure 1 The Y direction shown) and the third direction (i.e. Figure 1 The first direction, the second direction and the third direction are perpendicular to each other, but are not limited thereto, as long as the first direction, the second direction and the third direction intersect with each other respectively.

[0068] For example, reference Figures 1 to 3 The first driving mechanism 42 of the first curling device 40 includes a first driving member 420, a moving member 421, a first connecting member 422 and a second connecting member 423, wherein the moving member 421 moves along the second direction (i.e. Figure 3 The moving member 421 extends in the first direction (ie, the Y direction shown in FIG. 1 ) and is located in the above-mentioned sliding opening 20. Figure 3 The movable member 421 extends in the X direction as shown in the figure, so that the part of the movable member 421 facing the forming roller 3 exceeds the above-mentioned sliding port 20. The movable member 421 is sleeved on the above-mentioned two sliding rods 21. The movable member 421 is rectangular, but not limited to this, and can also be square, pentagonal, circular, etc.

[0069] Exemplarily, the moving member 421 has two openings along the third direction (i.e. Figure 3 The through holes 4210 are arranged in a spaced relationship along the second direction (ie, the Z direction shown in FIG. Figure 3 The two slide bars 21 pass through the corresponding through holes 4210 respectively to be slidably connected with the moving member 421. Along the first direction, the side of the moving member 421 away from the bottom plate 2 (i.e., the side facing the forming roller 3) is connected with two first ear blocks 424 spaced apart along the third direction, and the first ear blocks 424 are rotatably connected with the second driving mechanism 43.

[0070] Exemplarily, along the second direction, the side of the moving member 421 away from the second cylinder 50 is connected to the first driving member 420, and the first driving member 420 is used to drive the moving member 421 to move along the second direction (ie Figure 1 The first driving member 420 is a first cylinder 4200, but is not limited thereto. It may also be an electric push rod or other device as long as it can drive the moving member 421 to move along the second direction.

[0071] Exemplarily, the first connecting member 422 extends along the first direction and is rotatably connected to the second connecting member 423 via a pin shaft. The first connecting member 422 includes two first connecting members 422 spaced apart along the third direction. Both first connecting members 422 are connected to a side of the moving member 421 away from the top plate 1 .

[0072] For example, reference Figure 3 , the second connecting member 423 is along the first direction (ie Figure 3 The bottom end of the second connecting member 423 is rotatably connected to the side pressure roller 44 via a second rotating shaft 440. The side of the second connecting member 423 away from the side pressure roller 44 is connected to two connecting members extending in the third direction (i.e. Figure 3 The second ear block 425 is spaced apart from each other in the Z direction (as shown in the figure), one end of the second driving mechanism 43 is rotatably connected to the above-mentioned first ear block 424 through a pin, and the other end is rotatably connected to the second ear block 425 through a pin.

[0073] Exemplarily, the second driving mechanism 43 is an electric push rod 430 , but is not limited thereto, and may also be a structure such as a cylinder. The electric push rod 430 , the moving member 421 , the first connecting member 422 , and the second connecting member 423 together form a triangle.

[0074] For example, reference Figures 1 to 3 The first driving member 420 is used to drive the movable member 421 to move along the second direction, thereby driving the second connecting member 423 to move along the second direction, so that the side pressure roller 44 switches between the first position and the second position, and the second driving mechanism 43 is used to drive the second connecting member 423 to rotate relative to the first connecting member 422, so that the side pressure roller 44 switches between the first state and the second state.

[0075] Specifically, the first cylinder 420 drives the moving member 421 to move away from the forming roller 3 along the second direction (i.e. Figure 1 The first connecting member 422 connected to the moving member 421 moves synchronously, and the second connecting member 423 connected to the first connecting member 422 also moves synchronously, thereby driving the side pressure roller 44 connected to the second connecting member 423 to move away from the forming roller 3 along the second direction (i.e., Figure 1 c direction as shown) to convert the side pressure roller 44 from the first position to the second position.

[0076] At the same time, the electric push rod 430 moves toward the direction close to the moving member 421 (i.e. Figure 3 The side pressure roller 44 is connected to the second connection member 423 and the side pressure roller 44 is connected to the second connection member 423. ...2 and the side pressure roller 44 is connected to the second connection member 422. The side pressure roller 44 is connected to the second connection member 422 and the side pressure roller 44 is

[0077] In the first position, at least part of the side pressure roller 44 is located above the forming roller 3. Along the first direction, at least part of the side pressure roller 44 can contact the upper surface of the semi-finished product, and cooperate with the rotation of the forming roller 3 to apply pressure to the semi-finished product, thereby helping the various tire components to be better bonded together. At this time, the side pressure roller 44 is in the first state, that is, the first rotating shaft 30 is parallel to the second rotating shaft 440, so that at least part of the side pressure roller 44 located on the upper surface of the semi-finished product can be completely pressed on the upper surface of the semi-finished product to apply pressure to it.

[0078] In the second position, the side pressure roller 44 is not located above the forming roller 3, that is, it does not contact the upper surface of the semi-finished product. At this time, the side pressure roller 44 is in the second state, that is, the first rotating shaft 30 is perpendicular to the second rotating shaft 440, and along the second direction, the side pressure roller 44 is located on one side of the forming roller 3, and the second connecting member 423 is parallel to the forming roller 3.

[0079] When the side pressure roller 44 moves from the first position to the second position, it is simultaneously converted from the first state to the second state. At the same time, the surface of the side pressure roller 44 always maintains close contact with the surface of the forming roller 3, that is, the side pressure roller 44 moves along the second direction away from the forming roller 3, and at the same time, it is converted from being parallel to the forming roller 3 to being perpendicular to the forming roller 3. The overall running trajectory is arc-shaped, that is, the semi-finished product part in contact with the forming roller 3 also has the same arc-shaped running trajectory, thereby achieving the effect of curling one end of the semi-finished product inwardly. Combined with the heating function of the forming roller 3, the tire rim can be better shaped to form a green embryo for the next step of the process.

[0080] When the curling work is completed, the first cylinder 420 drives the moving member 421 to move toward the forming roller 3 along the second direction (i.e. Figure 1 The side pressure roller 44 is moved in the second direction toward the forming roller 3, so that the side pressure roller 44 is converted from the second position to the first position.

[0081] At the same time, the electric push rod 430 moves away from the moving member 421 (i.e. Figure 3 The side pressure roller 44 is extended in the f direction as shown to drive the second connecting member 423 rotatably connected thereto to rotate relative to the first connecting member 422 in the direction away from the forming roller 3, thereby driving the side pressure roller 44 connected to the second connecting member 423 to move along with the second connecting member 423, so that the side pressure roller 44 is converted from the second state to the first state. When the side pressure roller 44 switches from the second position to the first position, the electric push rod 430 drives the side pressure roller 44 to be converted from the second state to the first state, so that the forming roller 3 returns to its original position, that is, at least partially located above the forming roller 3, and the first rotating shaft 30 is parallel to the second rotating shaft 440.

[0082] It can be understood that the movement direction of the second curling device 41 is opposite to that of the first curling device 40. Specifically, for the first curling device 40, the direction away from the forming roller 3 is Figure 1 The c direction shown is close to the forming roller 3. Figure 1 As shown in the d direction, for the second hemming device 41, the direction away from the forming roller 3 is Figure 1The d direction shown is close to the forming roller 3. Figure 1 c direction shown.

[0083] For example, reference Figure 1 The forming roller 3 moves along the second direction (i.e. Figure 1 The forming roller 3 is a roller body that can be heated and cooled. Heating can soften the rubber of the tire components, so that the components are adhered together. At the same time, the main pressure roller 6 and the side pressure roller 44 described later are used to press and connect the various tire components together, and then the curling device 4 curls it. After the tire rim is formed on the green embryo, the forming roller 3 can cool and shape it. One device can complete the forming of the tire rim without the help of other curling devices and cooling devices, which is convenient for the production of green embryos, saves costs, and simplifies the process.

[0084] Exemplarily, the tire forming roller device also includes two third driving units 5 spaced apart along the second direction. The third driving unit 5 is disposed on the top plate 1 and is symmetrically arranged. It penetrates the top plate 1 and is connected to the bottom plate 2 to drive the bottom plate 2 to move up and down along the first direction. The third driving unit 5 is a second cylinder 50.

[0085] The embodiment of the present application does not limit the type of the third driving unit 5, and it can also be a device such as an electric push rod or a motor slider structure, as long as it can drive the base plate 2 to move up and down along the first direction. Similarly, the embodiment of the present application does not limit the number of the third driving unit 5, and it can also be set to one, three or other numbers.

[0086] Exemplarily, the second cylinder 50 penetrates the top plate 1 and connects the bottom plate 2 to the top plate 1, and can drive the bottom plate 2 to move along the first direction, so that the bottom plate 2 can drive the curling device 4 connected to the above-mentioned sliding mouth 20 on the bottom plate 2 to move along the first direction.

[0087] Specifically, when the feeding device is feeding, the second cylinder 50 can drive the bottom plate 2 and the curling device 4 to move upward along the first direction (i.e. Figure 1 The tire is preferably arranged in a direction a as shown in the figure, so that there is space between the side pressure roller 44 of the curling device 4 and the forming roller 3, which is convenient for the feeding device to lay various tire components on the surface of the forming roller 3, such as the tire bead, the wire layer, the inner liner and other components.

[0088] After the feeding device has laid out the various tire components, the second cylinder 50 can drive the bottom plate 2 and the crimping device 4 to move downward in the first direction (i.e. Figure 1The side pressure roller 44 of the curling device 4 is pressed against the surface of the semi-finished product formed by the various tire components. The second rotating shaft 440 and the forming roller 3 rotate continuously, driving the semi-finished product to rotate, so that the side pressure roller 44 in contact with the semi-finished product also rotates synchronously. The side pressure roller 44 cooperates with the rotation of the forming roller 3 to apply pressure to the semi-finished product. The forming roller 3 is heated to soften the rubber of the tire components, thereby bonding the various components together.

[0089] For example, continue to refer to Figure 1 Along the first direction, a side of the bottom plate 2 close to the forming roller 3 is connected to a U-shaped plate 23, and the bottom plate 2 is connected to the U-shaped plate 23 via two connecting rods 22 spaced apart along the second direction, and both connecting rods 22 extend along the first direction, and a main pressing roller 6 is rotatably connected to the middle of the U-shaped plate 23 via a bearing, and the main pressing roller 6 extends along the second direction, that is, the main pressing roller 6 is arranged on a side of the bottom plate 2 close to the forming roller 3, and is located between the two curling devices 4, and along the first direction, the bottom of the main pressing roller 6 and the bottom of the side pressing roller 44 are in the same plane.

[0090] Exemplarily, the U-shaped plate 23 is fixed to the middle of the base plate by two connecting rods 22, so that the main pressure roller 6 connected thereto is located in the middle of the tire forming roller device. When the side pressure roller 44 cooperates with the rotation of the forming roller 3 to apply pressure to the semi-finished product, the main pressure roller 6 can apply pressure to the semi-finished product synchronously with the side pressure roller 44, so that each tire component is subjected to greater pressure and can be bonded together faster and better; at the same time, the main pressure roller 6 is located between the two curling devices 4, so that the upper surface of the semi-finished product can be subjected to pressure and the upper surface can be evenly stressed.

[0091] The main pressure roller 6 and the side pressure roller 44 cooperate with the rotation of the forming roller 3 to apply pressure to the material. After the tire rim is formed, the first cylinder 4200 and the electric push rod 430 start to work, which can drive the two side pressure rollers 44 to rotate inward to close the side edges of the tire rim. At the same time, the two side pressure rollers 44 can be driven to move outward in accordance with their rotation speed. At this time, the side pressure rollers 44 are always in close contact with the material, so as to better cooperate with the rotation and curling work of the side pressure rollers 44. There is no need to purchase and use a curling device separately, which is convenient for the production of raw embryos.

[0092] Exemplarily, the above-mentioned first curling device 40 and second curling device 41 are symmetrically arranged, and the output ends of the two second cylinders 50 are also symmetrically fixed on the base plate 2. In addition, the U-shaped plate 23 is centrally fixed to the bottom of the base plate 2. Under such an arrangement, the main pressure roller 6 is centered in the entire structure. The staff only needs to install the overall structure on the top plate 1 centrally above the forming roller 3. The center vertical line of the forming roller 3 and the center vertical line of the top plate 1 coincide with each other. In this way, the first cylinder 4200, the moving part 421 and the electric push rod 430 and other structures symmetrically fixed on the top of the base plate 2 in the first curling device 40 and the second curling device 41 can be symmetrically arranged on both sides of the forming roller 3. In the subsequent feeding and green forming process of the blank, it can be smoothly coordinated with the shape of the forming roller 3 for shaping.

[0093] Exemplarily, along the second direction, both ends of the top plate 1 are fixed with fixing plates 10, and six mounting holes 11 are opened on the fixing plate 10, but it is not limited to this, and the number of holes 11 may be eight, nine, ten or other numbers, so that the staff can use bolts and nuts to fix and install the tire forming roller device. For example, it can be installed above the forming roller 3 in the workshop. The tire forming roller device can be fixed by fixing the top plate 1, and can be built on the ground with other auxiliary workpieces when necessary.
