Description

Technical Field

[0001] This invention relates to the field of air spring technology, and more specifically, to a top roller mechanism, a bonding device, an air spring forming machine, and a bonding method. Background Technology

[0002] In existing molding equipment, the bonding of rubber materials generally relies on a top roller located below the conveyor belt. This top roller rises and lifts the conveyor belt, pressing the conveyor belt and the bonding drum tightly together. However, for the processing of air springs, since the bonding conveyor belt and the bonding drum are in hard contact under the action of a single top roller, the rubber material used to process air springs is prone to sticking to the conveyor belt during actual bonding, making it very difficult for the rubber material to adhere to the molding drum. Summary of the Invention

[0003] The main objective of this invention is to provide a top roller mechanism, a bonding device, an air spring forming machine, and a bonding method to solve the problem that existing air spring forming equipment cannot achieve stable bonding of adhesive materials.

[0004] To achieve the above objectives, according to one aspect of the present invention, a top roller mechanism is provided, comprising: a first top roller for receiving a conveyor belt; a second top roller for receiving the conveyor belt, the first top roller and the second top roller being spaced apart and forming a bonding area for accommodating a bonding drum; and a driving member, wherein both the first top roller and the second top roller are drivenly connected to the driving member, the driving member driving the first top roller and the second top roller to move and approach the bonding drum, such that a portion of the bonding drum is located within the bonding area, and the adhesive on the conveyor belt within the bonding area is bonded to the bonding drum.

[0005] Furthermore, the top roller mechanism also includes a connector, which is connected to the drive component, and both the first top roller and the second top roller are rotatably connected to the connector.

[0006] Furthermore, the connector has a first connecting arm and a second connecting arm, with a groove between the first connecting arm and the second connecting arm serving as a mating area, and the first top roller and the second top roller are rotatably connected to the ends of the first connecting arm and the second connecting arm, respectively.

[0007] Furthermore, the first top roller and the second top roller are located below the bonding drum. The first top roller and the second top roller can be raised and lowered under the drive of the drive unit to bond the adhesive material closer to the bonding drum or to transport it away from the bonding drum.

[0008] According to another aspect of the present invention, a bonding device is provided, comprising: a bonding drum having a bonding position on its circumferential side; the aforementioned top roller mechanism having the bonding position facing the bonding area of ​​the top roller mechanism; a conveyor belt supported on a first top roller and a second top roller of the top roller mechanism, with adhesive material located on the conveyor belt, wherein when the first top roller and the second top roller move toward the bonding drum, the bonding drum squeezes the conveyor belt, and the adhesive material is bonded from the bonding position to the bonding drum.

[0009] Furthermore, the rotation direction of the bonding drum is the same as the conveying direction of the conveyor belt.

[0010] Furthermore, the top roller mechanism is located below the bonding drum, and the conveyor belt is located between the bonding drum and the top roller mechanism.

[0011] Furthermore, the axes of the first and second top rollers are parallel to the axis of the bonding drum.

[0012] According to another aspect of the present invention, an air spring forming machine is provided, including the above-described bonding device.

[0013] According to another aspect of the present invention, a bonding method is provided, employing the above-described top roller mechanism. The bonding method includes: when the adhesive material is conveyed to a predetermined position, a driving member drives a first top roller and a second top roller to lift up, a portion of the bonding drum is located in the bonding area, the conveyor belt and the bonding drum move simultaneously, and the adhesive material on the conveyor belt in the bonding area is bonded to the bonding drum.

[0014] By applying the technical solution of this invention, two top rollers, a first top roller and a second top roller, are arranged at intervals and offset from the bonding drum. This allows the bonding drum to engage with the bonding area. During normal material conveying, the drive unit does not drive the first and second top rollers, which remain in their initial positions. At this time, there is no compression between the bonding drum and the conveyor belt, allowing the conveyor belt to transport materials normally. During bonding, the drive unit drives the first and second top rollers to move closer to the bonding drum, thereby positioning a portion of the bonding drum within the bonding area. Within the bonding area, the bonding drum presses the conveyor belt supported by the two top rollers. More precisely, it presses the portion of the conveyor belt located within the bonding area, causing the adhesive on that portion of the conveyor belt to adhere to the bonding drum. During this bonding process, since the top rollers are not directly at the bonding position, but rely on the deformation of the conveyor belt to press the adhesive together with the bonding drum, this avoids excessive pressure from the top rollers causing the adhesive to stick to the conveyor belt. This results in a better bonding effect and a stable bond between the adhesive and the bonding drum, enabling stable bonding for adhesives of varying viscosities. Attached Figure Description

[0023] To address the problem that existing air spring forming equipment cannot achieve stable bonding of adhesive materials, this invention provides a top roller mechanism, a bonding device, an air spring forming machine, and a bonding method. The air spring forming machine includes the bonding device described below.

[0024] like Figure 1 and Figure 2The illustrated top roller mechanism for bonding air spring rubber material includes a first top roller 10 for receiving a conveyor belt 60, a second top roller 20 for receiving the conveyor belt 60, and a drive member 30. The first top roller 10 and the second top roller 20 are spaced apart and form a bonding area for accommodating a bonding drum 50. Both the first top roller 10 and the second top roller 20 are drivenly connected to the drive member 30. The drive member 30 drives the first top roller 10 and the second top roller 20 to move and approach the bonding drum 50, so that a portion of the bonding drum 50 is located within the bonding area, and the rubber material 70 on the conveyor belt 60 within the bonding area is bonded to the bonding drum 50.

[0025] This embodiment features two top rollers, a first top roller 10 and a second top roller 20, spaced apart and offset from the bonding drum 50. This allows the bonding drum 50 to engage with the bonding area. During normal conveying of the adhesive material 70, the drive unit 30 does not drive the first top roller 10 and the second top roller 20; both rollers remain in their initial positions. At this time, there is no compression between the bonding drum 50 and the conveyor belt 60, allowing the conveyor belt 60 to transport materials normally. During bonding, the drive unit 30 drives the first top roller 10 and the second top roller 20 towards the bonding drum 50, causing a portion of the bonding drum 50 to be positioned closer to the bonding area. Within the bonding area, the bonding drum 50 presses against the conveyor belt 60 supported by the two top rollers. More precisely, it presses against the portion of the conveyor belt 60 located within the bonding area, causing the adhesive 70 on that portion of the conveyor belt 60 to adhere to the bonding drum 50. During this bonding process, since the top rollers are not directly at the bonding position, but rather rely on the deformation of the conveyor belt 60 to press the adhesive 70 and the bonding drum 50 together, this avoids the phenomenon of excessive pressure from the top rollers causing the adhesive 70 to stick to the conveyor belt 60. This achieves a better bonding effect and ensures stable bonding between the adhesive 70 and the bonding drum 50, enabling stable bonding for adhesives 70 with different viscosities.

[0026] This embodiment uses the top roller mechanism for air spring processing, specifically its application in an air spring forming machine, as an example. Of course, it can also be applied to other tire processing equipment.

[0027] In this embodiment, the top roller mechanism further includes a connecting member 40, which is connected to the driving member 30. The first top roller 10 and the second top roller 20 are both rotatably connected to the connecting member 40. In this way, the driving member 30 is connected to the first top roller 10 and the second top roller 20 through the connecting member 40, thereby achieving the effect of the driving member 30 driving the first top roller 10 and the second top roller 20 to move synchronously, ensuring the synchronicity of their movements.

[0028] Specifically, the connector 40 in this embodiment includes a main body, a first connecting arm, a second connecting arm, and a drive connecting arm. The main body is the main part of the connector 40. In this embodiment, the main body is plate-shaped and its surface is approximately parallel to the conveying surface of the conveyor belt 60. The first connecting arm and the second connecting arm are spaced apart on the side of the main body and are located on the same side of the main body, thus naturally forming a groove between the first connecting arm and the second connecting arm. This groove serves as a contact area. The first top roller 10 and the second top roller 20 are rotatably connected to the ends of the first connecting arm and the second connecting arm, respectively. The drive connecting arm is also connected to the main body, but the drive connecting arm and the first connecting arm are located on opposite sides of the main body. That is, the first connecting arm and the second connecting arm are located on one side of the main body, while the drive connecting arm is located on the opposite side. The drive connecting arm connects to the drive member 30, enabling the drive member 30 to drive the first top roller 10 and the second top roller 20 to move synchronously through the connector 40. In this embodiment, the first connecting arm and the second connecting arm are located at opposite edges on one side of the main body, while the drive connecting arm is located in the middle area on the other side of the main body. This ensures the force balance of the connecting member 40, thereby ensuring the reliability of the structure.

[0029] Of course, the specific structure of the connector 40 is not limited to the structure described in this embodiment, and other structural forms of the connector 40 can be used as needed. Alternatively, the connector 40 can be omitted, and the drive component 30 can be directly driven and connected to the first top roller 10 and the second top roller 20. Or, multiple drive components 30 can be provided, for example, two drive components 30 can be provided, and the two drive components 30 can cooperate with the first top roller 10 and the second top roller 20 respectively. If the top rollers need to move synchronously, the synchronous movement of the two top rollers can be achieved by controlling the two drive components 30 to move synchronously through the program.

[0030] In this embodiment, the top roller structure is positioned below the bonding drum 50, more specifically, below the axis of the bonding drum 50. Specifically, the first top roller 10 and the second top roller 20 are located below the bonding drum 50. The first top roller 10, the second top roller 20, and the connecting member 40 are all height-adjustable, capable of rising and falling under the drive of the driving member 30. Thus, when the conveyor belt 60 is normally conveying, the first top roller 10 and the second top roller 20 are in a lower position, and the conveyor belt 60 is away from the bonding drum 50. At this time, the bonding drum 50 will not compress the conveyor belt 60, allowing the conveyor belt 60 to normally convey the adhesive material 7. When bonding is required, the conveyor belt 60 transports the adhesive material 70 directly below the bonding drum 50. At this time, the drive unit 30 causes the first top roller 10 and the second top roller 20 to rise and approach the bonding drum 50 through the drive connector 40. The conveyor belt 60 and the adhesive material 70 on it also approach the bonding drum 50 until the adhesive material 70 contacts the bonding drum 50. The two top rollers rise further, causing the bonding drum 50 to squeeze the conveyor belt 60, thereby bonding the adhesive material 70 onto the bonding drum 50, thus achieving the bonding of the adhesive material 70.

[0031] In this embodiment, the driving component 30 is a lifting cylinder. Of course, other driving components can also be used, and transmission components can be added as needed.

[0032] like Figure 1 and Figure 2 As shown, this embodiment also provides a bonding device for an air spring forming machine. The bonding device includes a bonding drum 50, the aforementioned top roller mechanism, and a conveyor belt 60. The bonding drum 50 has bonding positions on its circumferential side. Since the top roller mechanism is positioned below the bonding drum 50 in this embodiment, the bonding positions are located at the bottom of the bonding drum 50, thus facing the bonding area of ​​the top roller mechanism to ensure a stable bonding effect. The conveyor belt 60 is supported on the first top roller 10 and the second top roller 20 of the top roller mechanism, placing the conveyor belt 60 between the bonding drum 50 and the top roller mechanism. When the conveyor belt 60 moves, it drives the first top roller 10 and the second top roller 20 to rotate, and the adhesive material 70 is located on the conveyor belt 60. Thus, when the first top roller 10 and the second top roller 20 move towards the bonding drum 50, the bonding drum 50 can squeeze the conveyor belt 60, thereby causing the adhesive material 70 to be bonded from the bonding positions to the bonding drum 50.

[0033] In this embodiment, when the adhesive 70 is being bonded, the bonding drum 50 rotates, and the rotation direction of the bonding drum 50 is the same as the conveying direction of the conveyor belt 60. This ensures that the conveying direction of the conveyor belt 60 is the same as the tangential direction of the bonding position, thereby ensuring that the adhesive 70 is bonded to the bonding drum 50 along the rotation direction of the bonding drum 50, thus ensuring the bonding effect.

[0034] Preferably, the conveyor belt 60 in this embodiment is a flexible component. This allows the conveyor belt 60 to deform to a certain extent. When the bonding drum 50 is located within the bonding area, the bonding drum 50 can compress the conveyor belt 60, causing it to deform. This ensures that the conveyor belt 60 effectively compresses the adhesive material 70, guaranteeing that the conveyor belt 60 adheres to the molding drum. Furthermore, it prevents excessive force from the conveyor belt 60 on the adhesive material 70, which could cause the adhesive material 70 to stick to the conveyor belt 60.

[0035] In this embodiment, the axes of the first top roller 10 and the second top roller 20 are parallel to the axis of the bonding drum 50, thereby making the conveying direction of the conveyor belt 60 parallel to the tangential direction of the bottom of the bonding drum 50. It should be noted that the conveying direction of the conveyor belt 60 mentioned here refers to the direction of the conveyor belt 60 during normal conveying, while the direction in which it deforms under the pressure of the bonding drum 50 during bonding is not the actual conveying direction.

[0036] This embodiment also provides a bonding method using the above-described top roller mechanism. The bonding method specifically includes:

[0037] Rubber compound 70 is conveyed to the predetermined position by conveyor belt 60;

[0038] When the cylinder rod of the drive component 30 extends, it drives the first top roller 10 and the second top roller 20 to lift up. Under the action of the two top rollers, the conveyor belt 60 presses the adhesive 70 onto the bonding drum 50. At this time, a part of the bonding drum 50 is located in the bonding area.

[0039] The conveyor belt 60 and the bonding drum 50 move simultaneously, and the adhesive material 70 on the conveyor belt 60 in the bonding area is bonded to the bonding drum 50, so that the joint of the adhesive material 70 is bonded on the bonding drum 50.

[0040] The drive component 30 retracts, and the first top roller 10 and the second top roller 20 return to their downward positions, thus completing one bonding process.

[0041] It should be noted that "multiple" in the above embodiments refers to at least two.

[0042] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0043] 1. This technology solves the problem that existing air spring molding equipment cannot achieve stable bonding of the adhesive material;

[0044] 2. It avoids the phenomenon of the rubber material sticking to the conveyor belt due to excessive lifting pressure of the top roller, thereby achieving a better bonding effect and realizing stable bonding between the rubber material and the bonding drum;

[0045] 3. Stable bonding can be achieved for adhesives with different viscosity.
