Description

Technical Field

[0001] The utility model relates to the field of tires, in particular to a tire molding exhaust device and a tire molding machine. Background Art

[0002] During the tire forming process, the sidewall and the carcass will be bonded together to produce gaps and accumulate gas. If these accumulated gases cannot be discharged in the subsequent forming or vulcanization process, bubbles will be generated on the finished tire, affecting the quality of the tire. In order to solve the problem of air traps, the traditional production process will manually puncture exhaust holes at the inspection station after the tire embryo is formed, which is inefficient, labor-intensive, and the quality of the holes is not standard, affecting the efficiency of the tire forming machine. With the development of technology, a special puncturing device is generally configured in the tire forming machine feeding system to pre-puncture the corresponding parts of the sidewall before the rubber is drum-bonded. The puncturing structure is that the needle is vertically installed on a flat plate and moves longitudinally through the lifting mechanism, so that the puncturing needle falls and pierces the sidewall or lifts up and detaches. However, due to the inconsistent movement speed of the needle and the rubber, the rubber is stretched, affecting the quality of the tire, and the puncturing action is discontinuous and inefficient. When the needle is separated from the rubber, it is easy to stick to the material and stretch the rubber. The spacing of the needle is fixed, and the puncture position is inconvenient to adjust and cannot be automatically matched. In addition, when the carcass is rolled, it is easy to cause the exhaust hole to be closed, and the exhaust effect is poor. Utility Model Content

[0003] The main purpose of the utility model is to provide a tire molding exhaust device and a tire molding machine, so as to solve the problem that the tire quality is affected when the tire puncturing device in the prior art punctures a hole.

[0004] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a tire forming exhaust device is provided, including a base, a swing mechanism, a pressure roller, and a licker-in roller, the swing mechanism is movably connected to the base, and at least a part of the swing mechanism is rotatably arranged relative to the base; the pressure roller is rotatably connected to the swing mechanism and moves synchronously with the swing mechanism; the licker-in roller is rotatably connected to the swing mechanism and rotates synchronously with the swing mechanism, and the pressure roller and the licker-in roller are located on opposite sides of the swing mechanism.

[0005] Furthermore, the swing mechanism includes a mounting seat, a swing frame, and a mounting shaft. The mounting seat is movably connected to the base; the swing frame is rotatably connected to the mounting seat; the mounting shaft is passed through the swing frame, and the pressure roller and the licker-in roller are both connected to the mounting shaft and are respectively located at both ends of the mounting shaft.

[0006] Further, an axis connection is formed between the installation axis and the swing frame, and the distance between the axis connection and the pressure roller is less than or equal to the distance between the axis connection and the licker-in roller.

[0007] Furthermore, there are multiple swing mechanisms, and they are arranged in sequence along the moving direction of the swing mechanism relative to the base. The axis of the mounting shaft is parallel to the moving direction of the swing mechanism relative to the base. In two adjacent swing mechanisms, the pressure roller is located at one end of the mounting shafts of the two swing mechanisms that are close to each other.

[0008] Furthermore, the licker-in roller comprises a roller body and a plurality of licker-in needles. The roller body is rotatably arranged relative to the swing mechanism. The licker-in needles are detachably arranged on the circumferential side surface of the roller body and are arranged along the circumferential direction and / or axial direction of the roller body.

[0009] Furthermore, at least part of the needles are arranged along the axial direction of the roller body, and the needles arranged along the axial direction of the roller body are arranged in a spiral shape along the circumferential side surface of the roller body.

[0010] Furthermore, the needle is tapered, and the diameter of the needle gradually decreases in a direction away from the peripheral surface of the roller body.

[0011] Furthermore, the tire forming exhaust device also includes a connecting seat and a connecting shaft, wherein the connecting seat is connected to the swing mechanism; the connecting shaft is connected to the connecting seat, and the licker-in roller is sleeved on the outside of the connecting shaft and is rotatable relative to the connecting seat.

[0013] According to another aspect of the utility model, a tire building machine is provided, comprising the tire building exhaust device mentioned above.

[0014] By applying the technical solution of the utility model, the stretching of the tire rubber compound by the licker-in roller when puncturing and venting the tire is reduced through a passive puncturing method, thereby improving the tire quality.

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0024] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0025] In order to solve the problem in the prior art that the tire puncturing device affects the tire quality when puncturing, the utility model provides a tire molding exhaust device and a tire molding machine, wherein the tire molding machine includes the following tire molding exhaust device.

[0026] like Figures 1 to 4A tire forming exhaust device shown includes a base 10, a swing mechanism 20, a pressure roller 30, and a licker-in roller 40. The swing mechanism 20 is movably connected to the base 10, and at least a portion of the swing mechanism 20 is rotatably arranged relative to the base 10; the pressure roller 30 is rotatably connected to the swing mechanism 20 and moves synchronously with the swing mechanism 20; the licker-in roller 40 is rotatably connected to the swing mechanism 20 and rotates synchronously with the swing mechanism 20, and the pressure roller 30 and the licker-in roller 40 are located on opposite sides of the swing mechanism 20.

[0027] The present embodiment reduces the stretching of the tire rubber material when the licker-in roller 40 punctures and vents the tire by passive puncturing, thereby improving the tire quality. Specifically, on the one hand, the licker-in roller 40 and the pressure roller 30 are all concentrated on the swing mechanism 20 and share a set of swing mechanisms 20, so that the licker-in roller 40 and the pressure roller 30 can move to a suitable puncturing position or rolling position with the movement of the swing mechanism 20, which can save costs. On the other hand, the licker-in roller 40 is rotatably connected to the swing mechanism 20. When the licker-in roller 40 is located at the puncturing position and acts on the tire, the rotation of the tire drives the licker-in roller 40 to rotate, so that the licker-in roller 40 cooperates with different positions of the tire circumference to puncture and vent, thereby realizing the automatic insertion and automatic withdrawal of the licker-in roller 40 into the tire. With the structural form of the licker-in roller 40, the licker-in roller 40 can be pressed near the punctured position when partially withdrawing from the tire, thereby reducing the stretching of the tire rubber material and improving the tire quality. In addition, the density of the vent holes can be adjusted by adjusting the number of tire rotations, thereby realizing the infinite adjustment of the vent hole arrangement.

[0028] In this embodiment, the licker-in roller 40 is integrated into the swing mechanism 20, so that the licker-in roller 40 can move along the axial direction of the tire and can adjust the angle along the radial direction of the tire to achieve the puncture and exhaust of the tire. Specifically, the swing mechanism 20 is rotatably connected to the base 10, and the licker-in roller 40 is rotatably connected to the swing mechanism 20, so that the licker-in roller 40 can produce relative rotation with the base 10, and the swing mechanism 20 is movably connected to the base 10, so that the licker-in roller 40 integrated in the swing mechanism 20 can produce horizontal displacement of the tire axial direction with the base 10. In this way, the licker-in roller 40 can not only adjust the angle by rotating, so as to switch between the state of cooperating with the axial surface of the tire and the radial surface of the tire, so that the licker-in roller 40 can complete the exhaust action by puncturing the axial or radial surface of the tire, but also can adjust the horizontal position to cooperate with different positions of the tire to meet the exhaust requirements of different axial positions of the tire.

[0029] In this embodiment, the swing mechanism 20 includes a mounting seat 21, a swing frame 22, and a mounting shaft 23. The mounting seat 21 is movably connected to the base 10; the swing frame 22 is rotatably connected to the mounting seat 21; the mounting shaft 23 is arranged on the swing frame 22, and the pressure roller 30 and the licker-in roller 40 are both connected to the mounting shaft 23 and are respectively located at both ends of the mounting shaft 23. Specifically, in this embodiment, a screw mechanism is arranged between the mounting seat 21 and the base 10, and the screw mechanism is used to realize the lateral movement of the mounting seat 21 relative to the base 10, more specifically, the axial movement along the forming drum, so as to adjust the position of the mounting seat 21 and its upper components at the side and end surface of the forming drum. The swing frame 22 plays the role of driving the mounting shaft 23 and its upper components to rotate, so as to adjust the angle. The swing frame 22 of this embodiment is arranged longitudinally relative to the rotation axis of the mounting seat 21, and the rotation axis is perpendicular to the moving trajectory of the screw mechanism. The mounting shaft 23 is transversely penetrated at the upper end of the swing frame 22, and the axis of the mounting shaft 23 is parallel to the moving trajectory of the screw mechanism. Both ends of the mounting shaft 23 pass through the swing frame 22, so that the pressure roller 30 and the licker-in roller 40 can be fixed at both ends of the same mounting shaft 23. In this way, the two rollers share the same swing frame 22 and the mounting seat 21. The swing frame 22 drives the mounting shaft 23 and thus drives the pressure roller 30 and the licker-in roller 40 to move, so that the pressure roller 30 rolls and the licker-in roller 40 punctures holes for exhaust, thereby realizing the integrated setting of rolling and exhaust.

[0030] Optionally, the specific structure of the swing frame 22 can be set accordingly. It can be set to only one or multiple. When multiple swing frames 22 are set, each swing frame 22 can be connected in series and rotatably connected to each other, and an angle is formed between the rotation axes, so as to achieve adjustment in multiple directions and angles. Specifically, in this embodiment, there are two swing frames 22, namely a first swing frame rotatably connected to the mounting seat 21 and a second swing frame rotatably connected to the first swing frame. The other end of the second swing frame is connected to the mounting shaft 23. The rotation axis of the first swing frame is perpendicular to the rotation axis of the second swing frame. On the one hand, the first swing frame can rotate around the mounting seat 21, and its rotation axis is perpendicular to the tire axis. Figure 1 The up and down directions in the tire make the first swing frame able to adjust the angle formed with the tire by rotating, which is called left and right swinging. The left and right swinging can drive the pressure roller 30 and the licker-in roller 40 to rotate from the axial direction of the tire to the radial direction of the tire, so that the pressure roller 30 and the licker-in roller 40 are always parallel to the action surface to meet the requirements of the pressure roller 30 and the licker-in roller 40 working on the circumferential surface and the sidewall surface of the tire. On the other hand, the second swing frame can rotate around the first swing frame, and its rotation axis is perpendicular to the rotation axis of the first swing frame and parallel to the extension direction of the rotation axis, that is, Figure 1 The left and right directions in Figure 3The left and right directions in the forming drum are called forward and backward swinging. The forward and backward swinging enables the second swinging frame to drive the pressing roller 30 and the licker-in roller 40 to adjust the distance from the tire surface, so that the pressing roller 30 or the licker-in roller 40 opposite to the tire surface is pressed on the tire surface, and the forming drum drives the tire to rotate to complete the rolling or puncturing action. In addition, the mounting seat 21 can move along the tire axial direction, thereby driving the pressing roller 30 and the licker-in roller 40 to move along the tire axial direction, so as to match different axial positions of the tire.

[0031] It should be noted that the drive of the first swing frame rotating around the mounting seat 21 can be set to be a motor drive with a worm gear transmission to provide power for left and right swinging and achieve angle adjustment. In this way, the positioning is controlled by the servo system, with good stability and strong controllability. The drive of the second swing frame rotating around the first swing frame can be set to be a cylinder drive, and the pressure roller 30 is driven to realize its swinging along the radial direction of the tire when the pressure roller 30 acts on the circumferential surface of the tire to perform a rolling action, and the pressure roller 30 is driven to adjust the position of the tire side when the pressure roller 30 acts on the side of the tire to perform a puncture action, and a proportional valve can be added to adjust the cylinder pressure to control the rolling pressure to ensure that each layer of rubber is evenly compacted and free of bubbles, or the puncture pressure is adjusted when the puncture action is performed by the puncture roller 40 to ensure that the roller shaft can always pierce when it acts on different positions of the tire. Of course, the setting mode and driving mode of the swing frame 22 are not limited to this embodiment, and can also be set to other modes, which can meet the left and right swinging, front and back swinging and axial movement of the pressure roller 30 and the puncture roller 40.

[0032] In this embodiment, the installation shaft 23 and the swing frame 22 form an axis connection, and the distance between the axis connection and the pressure roller 30 is less than or equal to the distance between the axis connection and the licker-in roller 40. Figure 2 As shown, the outer side of the mounting shaft 23, i.e., one end away from the tire center, is provided with a licker-in roller 40, and the other end is provided with a pressure roller 30, and the shaft connection is provided between the licker-in roller 40 and the pressure roller 30 and close to the pressure roller 30, so that when the licker-in roller 40 acts on the tire side surface (i.e. Figure 3 The distance from the mounting shaft 23 enables the licker-in roller 40 to extend to a position closer to the center of the tire, meeting the requirement of puncturing a larger area. Moreover, since the pressure roller 30 relies on the side inclined surface position when rolling, and the licker-in roller 40 relies on the circumferential surface when puncturing, the positional relationship of the shaft connection enables the circumferential surface of the licker-in roller 40 to contact the tire surface as much as possible, thereby ensuring the puncturing effect. At the same time, the pressure roller 30 and the licker-in roller 40 are respectively arranged at one end, so that the pressure roller 30 does not interfere with the tire when rolling and puncturing.

[0033] Optionally, the number of the swing mechanisms 20 can be set as needed, and one or more can be set. In this embodiment, there are multiple swing mechanisms 20, and they are arranged in sequence along the moving direction of the swing mechanisms 20 relative to the base 10, that is, the two swing mechanisms 20 are both arranged on a set of screw mechanisms, and the axis of the mounting shaft 23 is parallel to the moving direction of the swing mechanism 20 relative to the base 10, so that the pressure roller 30 and the licker-in roller 40 can move along the tire axial direction, so that the pressure roller 30 and the licker-in roller 40 can act on different positions in the tire axial direction. In two adjacent swing mechanisms 20, the pressure roller 30 is located at one end of the mounting shafts 23 of the two swing mechanisms 20 that are close to each other, such as in this embodiment. Figure 2 As shown, two oscillating mechanisms 20 are symmetrically arranged, and the pressure rollers 30 of the two oscillating mechanisms 20 are arranged close to each other. The two oscillating mechanisms 20 can realize symmetrical separation and combination under the drive of the separation and combination driving device (i.e., the aforementioned device that enables the mounting seat 21 to generate movement relative to the base 10 along the tire axial direction), so that the pressure roller 30 can realize symmetrical separation and combination along the tire axial direction under the drive of the oscillating mechanism 20, so as to act on different positions of the circumferential surface of the tire. When the mounting shaft 23 needs to adjust the angle to act on the sidewall surface, the two oscillating mechanisms 20 are driven to rotate in opposite directions to act on the two surfaces of the sidewall respectively. In this way, the two oscillating mechanisms 20 can drive the pricking roller 40 and the pressure roller 30 to flexibly act on the circumferential side and two sidewall surfaces of the tire, and complete the puncture, exhaust and rolling actions at different positions.

[0034] In this embodiment, the licker-in roller 40 includes a roller body 41 and a plurality of thorns 42. The roller body 41 is rotatably arranged relative to the swing mechanism 20, so that when the licker-in roller 40 acts on the tire surface, the thorns 42 can be separated from the rubber material by the rotation of the roller body 41, so as to avoid the stretching of the rubber material caused by the untimely separation of the thorns 42, which affects the quality of the tire; the thorns 42 are detachably arranged on the circumferential surface of the roller body 41, so that the thorns 42 can be replaced individually after being damaged, and the remaining thorns 42 can be retained and continued to be used, saving maintenance costs; the thorns 42 are arranged along the circumference and axial direction of the roller body 41, so that when the thorns 42 act on the tire, the tire rotates and drives the roller body 41 to rotate, so that part of the thorns 42 are separated from the tire, and the other part of the thorns 42 are inserted into the tire. The density of the exhaust holes can be adjusted by setting the number of tire rotations, which is more flexible and changeable. Of course, the thorns 42 can also be arranged only along the circumference of the roller body 41 or only along the axial direction of the roller body 41 to adjust the density of the exhaust holes inserted into the tire.

[0035] like Figure 4As shown, in this embodiment, at least part of the needles 42 are arranged along the axial direction of the roller body 41, and the needles 42 arranged along the axial direction of the roller body 41 are arranged in a spiral shape along the circumferential surface of the roller body 41. In this way, when the pricking roller 40 acts on the tire surface, the roller body 41 rotates to any position to ensure that there are always needles 42 piercing the tire to ensure the effectiveness of the tire molding exhaust device, while avoiding the entire row of needles 42 from piercing or withdrawing. Instead, the needles 42 pierce and withdraw in sequence, reducing the impact on the rubber material and ensuring the processing quality. It should be noted that the axial arrangement shown here is not a strict axial arrangement. The needles 42 can be arranged along the axial direction of the roller body 41 as a whole, and they can have certain factors such as inclination.

[0036] In this embodiment, the needle 42 is tapered, and the diameter of the needle 42 gradually decreases in the direction away from the peripheral surface of the roller body 41. On the one hand, the needle 42 can penetrate the tire with the smallest diameter, so that the swing mechanism 20 can apply a smaller force to the needle 42 to make it penetrate the tire to exhaust air, thereby improving efficiency. On the other hand, the needle 42 is separated from the tire with a gradually decreasing diameter, making it easier for the needle 42 to separate from the tire, thereby reducing the stretching of the tire rubber by the needle 42.

[0037] In this embodiment, the tire forming exhaust device further includes a connecting seat 50 and a connecting shaft 60. The connecting seat 50 is connected to the swing mechanism 20. Preferably, the connecting seat 50 is positioned and connected to the mounting shaft 23 of the swing mechanism 20 through a flat key, so that the swing mechanism 20 can drive the pricking needles 42 to move; the connecting shaft 60 is connected to the connecting seat 50, and the pricking roller 40 is sleeved on the outer side of the connecting shaft 60 and is rotatable relative to the connecting seat 50, that is, the pricking roller 40 is connected to the connecting seat 50 at both ends of the connecting shaft 60 and is fixed on the connecting seat 50. The pricking roller 40 can rotate relative to the connecting seat 50 by rotating relative to the connecting shaft 60. The pricking roller 40 can also rotate together with the connecting shaft 60 and rotate relative to the connecting seat 50, so that when the pricking roller 40 acts on the tire surface, it can complete the insertion of part of the pricking needles 42 and the withdrawal of another part of the pricking needles 42 by rotation, thereby continuously completing the puncturing action.

[0038] In this embodiment, the base 10 includes a first base 11 and a second base 12, the second base 12 is movably connected to the first base 11, and the swing mechanism 20 is connected to the second base 12, and an angle is formed between the moving direction of the second base 12 relative to the first base 11 and the moving direction of the swing mechanism 20 relative to the second base 12. Figure 3As shown, the second seat body 12 is horizontally arranged and installed on the first seat body 11 through a guide device such as a guide rail, so that the second seat body 12 can accurately extend or return to a specific position along the tire radial direction, so that the licker-in roller 40 can accurately act on different positions of the sidewall surface. In this embodiment, the moving direction of the second seat body 12 relative to the first seat body 11 is perpendicular to the moving direction of the swing mechanism 20 relative to the second seat body 12 and perpendicular to the axial direction of the tire, so that when the licker-in roller 40 acts on the sidewall surface, it can move along the tire radial direction, so that the licker-in roller 40 can act on the sidewall surface close to the tire molding exhaust device, and can penetrate into the center of the tire and act on the sidewall surface close to the center of the tire.

[0039] The specific working process of the tire forming exhaust device is as follows: the carcass tube is inflated and shaped and combined with the belt layer-tread assembly, waiting for forming rolling; Figure 2 As shown, the pressure roller 30 installed on the base 10 extends radially along the forming drum to the pressing position, the cylinder extends, drives the pressure roller 30 to swing, so that the pressure roller 30 presses on the tire surface, the forming drum drives the tire to rotate, and the separation and combination drive device drives the pressure roller 30 to separate and combine symmetrically along the tire axis. The cylinder pressure is adjusted by the proportional valve to control the rolling pressure, so as to achieve the pressing of the tread and shoulder parts, and ensure that each layer of rubber is evenly compacted without bubbles. After the pressure roller 30 finishes rolling, the cylinder returns, the pressure roller 30 is lifted from the tire surface, and the base 10 moves to the puncture position; as shown in FIG. Figure 3 As shown, the separation and combination driving device drives the pressing roller 30 and the pricking roller 40 to separate and combine to the puncturing position, and the pricking roller 40 is driven by the swing mechanism 20 to press on the tire side surface, and then the forming drum rotates, and each pricking needle 42 sequentially pierces the tire side surface prone to air pockets as the forming drum rotates to discharge the gas in the bubbles.

[0040] It should be noted that, the multiple in the above embodiments refers to at least two.

[0042] 1. Solve the problem of poor tire exhaust effect in the prior art;

[0043] 2. Integrating the licker-in roller and the pressure roller on the same mounting shaft can meet the exhaust requirements of different positions and save driving costs;
