Description

Technical Field

[0001] This application relates to the field of tire manufacturing equipment technology, and more specifically, to a belt layer bonding drum with an electromagnetic device. Background Technology

[0002] Tire carcasses are mainly produced by assembling various semi-finished rubber compounds and carcass materials on a molding machine. Among them, the belt layer is an important component of the tire structure, which enhances the rigidity of the tire structure and restricts the circumferential deformation of the tire. The belt layer is made by bonding various belt layer materials layer by layer on a belt layer bonding drum, and the precision of the bonding process directly affects the quality and service life of the tire.

[0003] Because the surface of the belt layer bonding drum is a smooth curved surface, the belt layer material is prone to detaching from the bonding drum during bonding. To ensure that the belt layer material can be firmly bonded, the existing technology generally adopts the method of embedding magnets on the bonding drum, as follows: When the bonding drum is performing the adhesive application operation, the magnets on the belt layer adhesive drum can generate a strong attraction force, firmly adsorbing the belt layer material onto the drum surface. At the same time, the forming machine drives the bonding drum to rotate for application. After the belt layer material and the tire crown component are bonded on the bonding drum, the belt layer transfer ring moves over to clamp the bonded belt layer assembly and moves the belt layer assembly to the next process after the bonding drum shrinks. During this process, the magnets on the drum constantly generate an attractive force. When the transfer ring clamps and removes the belt layer assembly from the bonding drum, this attractive force can easily cause deformation or delamination of the belt layer assembly, resulting in unstable tire quality and affecting the normal operation of subsequent processes. Additional time and manpower are required for repair, adjustment, or re-production, increasing production costs and time, and severely impacting tire production efficiency. Therefore, there is an urgent need for a belt layer bonding drum that can solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, the present invention provides a belt layer bonding drum with an electromagnetic device, solving the problem that existing magnetic adsorption devices easily cause deformation or delamination of the belt layer assembly. It includes a main shaft, a drum plate, and guide rail assemblies. Multiple guide rail assemblies are circumferentially arranged on the outer side of the main shaft. Each guide rail assembly includes radially arranged guide rails and guide rail sliders slidably connected to the guide rails, with the guide rail sliders connected to the drum plate. A drum core is axially arranged on the main shaft, and a piston assembly is slidably connected to the inner cavity of the drum core. One end of the piston assembly is connected to a drive assembly, and the other end is connected to a connecting rod, which is connected to the drum plate. An electromagnetic assembly is provided on the drum plate, connected to a PLC control assembly, which is connected to the drive assembly.

[0005] Preferably, the main shaft is provided with an axial positioning block to limit the shrinkage diameter of the drum plate.

[0006] Preferably, the axial positioning block is equipped with a position sensor, which is electrically connected to the PLC control component.

[0007] Preferably, the PLC control component is electrically connected to a display screen for interactive operation by staff.

[0010] Preferably, the electromagnetic component is centrally positioned on the drum plate.

[0011] Preferably, the drum plate is provided with guide plates at both ends to limit the position of the belt layer material.

[0012] The beneficial effects of this invention are as follows: An electromagnetic component is provided on the drum plate, which is connected to a PLC control component, which in turn is connected to a drive component. Through its connection with the drive component, the PLC control component can receive a start signal from the drive component, thereby controlling the electromagnetic component to cut off power.

Flexible adjustment based on different belt layer materials enables precise control of the adsorption force, improving the bonding effect and expanding its applicability. Attached Figure Description

[0020] The present application will now describe a belt-layer bonding drum with an electromagnetic device according to an embodiment of this application.

[0021] Please see Figure 1 and Figure 2 This is a schematic diagram of the structure of the present invention. The belt-layer bonding drum with an electromagnetic device includes a main shaft 1, a drum plate 2, and a guide rail assembly. Multiple guide rail assemblies are arranged circumferentially on the outer side of the main shaft 1. Each guide rail assembly includes a radially arranged guide rail and a guide rail slider 3 slidably connected to the guide rail. The guide rail slider 3 is connected to the drum plate 2. A drum core 4 is arranged axially on the main shaft 1. A piston assembly 5 is slidably connected to the inner cavity of the drum core 4. One end of the piston assembly 5 is connected to a drive assembly, and the other end is connected to a connecting rod 6. The connecting rod 6 is connected to the drum plate 2. Specifically, the piston assembly 5 includes a piston rod and a piston disc connected together. The piston rod is connected to the drive assembly, and the piston disc is connected to the connecting rod 6. The drive assembly drives the piston rod to move, and the piston disc drives the connecting rod 6 to rise and fall, thereby controlling the rise and fall of the drum plate 2 connected to the connecting rod 6, realizing the extension and retraction of the bonding drum. An electromagnetic assembly 7 is provided on the drum plate 2. The electromagnetic assembly 7 is connected to a PLC control assembly, and the PLC control assembly is connected to the drive assembly.

[0022] When the bonding drum begins the adhesive application process, it rotates, and the belt layer material gradually spreads on the surface of the drum plate 2. Simultaneously, the electromagnetic component 7 is energized, generating an adsorption force to attract the adhesive material on the drum plate 2, ensuring accurate positioning and stable bonding, and preventing slippage during the bonding process. When the bonding drum completes the adhesive application, the drive component moves the piston component 5 within the drum core 4, which, via the connecting rod 6, moves the drum plate 2 radially along the guide rail, causing the bonding drum diameter to decrease and shrink. At this time, the PLC control component, connected to the drive component, receives a start signal from the drive component, thereby controlling the electromagnetic component 7 to de-energize. The electromagnetic component 7 can also be manually de-energized. After the electromagnetic component 7 is de-energized, the adsorption force on the bonded belt layer assembly disappears, preventing deformation or detachment of the assembly when the transfer ring clamps it. The electromagnetic component 7 ensures the accuracy of the rubber compound's position and the stability of the bonding process, resulting in good bonding effect, high and stable quality of the tire products, reduced defect rate, guaranteed normal operation of subsequent processes, and improved tire production efficiency.

[0023] Specifically, the PLC control component can regulate the current supplied to the electromagnetic component 7, thereby effectively controlling the adsorption force. Flexible adjustment based on different belt layer materials enables precise control of the adsorption force, improving the bonding effect and expanding its applicability.

[0024] Furthermore, the main shaft 1 is provided with an axial positioning block that limits the shrinkage diameter of the drum plate 2.

[0025] Furthermore, a position sensor is installed on the axial positioning block, and the position sensor is electrically connected to the PLC control component. When the piston assembly 5 moves to the axial positioning block, the diameter of the bonding drum expands and contracts to its minimum value. The position sensor detects the piston assembly 5 and transmits a signal to the PLC control component. The PLC control component then controls the electromagnetic component 7 to cut off power. Through this double-safety mechanism, the possibility of missed power cuts due to various possible unexpected situations is effectively avoided, thereby ensuring the stability and accuracy of the entire bonding drum workflow.

[0026] Furthermore, the PLC control component is electrically connected to a display screen for interactive operation by the staff. The display screen can show information such as the current diameter of the belt layer bonding drum, and the staff can adjust the attraction force of the electromagnetic component 7 through the display screen.

[0027] In one embodiment, the main shaft 1 is symmetrically provided with a left disk 8 and a right disk 9 at both ends, and the display screen is set on the left disk 8 or the right disk 9.

[0028] Furthermore, multiple guide rail components are evenly distributed to ensure that the belt layer material is evenly distributed during the bonding process, without local accumulation or loosening, thus avoiding affecting the bonding accuracy.

[0029] Furthermore, the electromagnetic component 7 is centrally positioned on the drum plate 2 to ensure that the adsorption force on each part of the belt layer material is uniform.

[0030] Furthermore, guide plates are provided at both ends of the drum plate 2 to limit the belt layer material and prevent the belt layer material from deviating.

[0031] The usage process of this utility model is as follows: When the bonding drum begins the adhesive application operation, the bonding drum rotates, and the belt layer material gradually spreads on the surface of the drum plate 2; at the same time, the electromagnetic component 7 is energized to attract the adhesive on the drum plate 2. When the bonding drum completes the adhesive application operation, the drive component drives the piston component 5 to move in the inner cavity of the drum core 4, and drives the drum plate 2 to move radially along the guide rail through the connecting rod 6, so that the diameter of the bonding drum becomes smaller and shrinks; at the same time, the PLC control component controls the electromagnetic component 7 to be de-energized, or the electromagnetic component 7 can be de-energized manually; the transfer ring performs a clamping operation on the assembly.

[0032] In this invention, an electromagnetic component 7 is provided on the drum plate 2. The electromagnetic component 7 is connected to a PLC control component, which is connected to a drive component. Through its connection with the drive component, the PLC control component can receive a start signal from the drive component, thereby controlling the electromagnetic component 7 to cut off power. The electromagnetic component 7 ensures the accuracy of the rubber compound's position and the stability of the bonding process, resulting in good rubber compound bonding, high and stable tire product quality, reduced defect rate, and guaranteed normal operation of subsequent processes, thus improving tire production efficiency. The PLC control component can regulate the current flowing into the electromagnetic component 7, thereby effectively controlling the adsorption force. Flexible adjustment based on different belt layer materials enables precise control of the adsorption force, improving the bonding effect and applicability.

[0033] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
