Description

Technical Field

[0001] The invention relates to the technical field of rubber roller manufacturing, in particular to a weighable bed for a rubber roller winding machine and a rubber roller winding machine comprising the bed. Background Art

[0002] The bed of the rubber roller winding machine is a structure used to support and drive the workpiece to rotate so that the rubber strip can be wound around the workpiece to complete the rubber coating operation. In recent years, with the continuous development of economic technology and the rubber industry, the market demand for rubber rollers has continued to increase, while the tonnage of rubber rollers has also become larger and larger, and the shape of the roller core and the type of rubber rollers have also tended to be diversified. For example, some large rubber fender products have a diameter of 4 meters and a tonnage of hundreds of tons to meet the requirements of offshore platforms for the berthing of large tonnage ships. This type of rubber roller has the characteristics of large workpiece diameter, complex roller core shape, and thick rubber coating. It often takes dozens of tons of rubber to process a rubber fender product. At this time, estimating and monitoring the amount of rubber becomes a major problem, which brings difficulties to the preparation of rubber materials. Because the rubber refining process requires a complex process flow, insufficient preparation of rubber materials delays production, and excessive preparation of rubber materials leads to waste of rubber materials because the rubber materials added to the vulcanizer cannot be stored for too long, and it is also impossible to intuitively obtain the information on the amount of rubber used in the product. Summary of the invention

[0003] In order to address the deficiencies in the prior art, the present invention discloses a weighable bed structure for a rubber roller winding machine, which can support and drive rubber rollers with a diameter of up to ∮3500mm, a weight of up to 70 tons, and unlimited length, and can monitor weight changes in real time and transmit them to the system so that users can view weight changes in real time. The machine is particularly suitable for the production of large rubber roller products.

[0004] The present invention is achieved through the following technical solutions:

[0005] In the first aspect, the present invention proposes a weighable bed for a rubber roller winding machine, which includes a bed head drive device, a bed chassis, a chuck, and a rubber roller bracket; the rubber roller bracket includes a base, a roller frame, a roller frame load-bearing wheel, a screw lifter, a weighing sensor and a bracket drive device, the base is installed on the bed chassis, the roller frame is installed on the inner side of the base, and an adjustable roller frame load-bearing wheel is installed on the upper end of the roller frame for supporting the shaft head of the roller core, and a lifting mechanism is installed at the lower end of the roller frame, and a weighing sensor is installed on the upper end of the lifting mechanism for weighing the weight of the roller core and real-time monitoring of the amount of rubber used; the bracket drive device is used to drive the rubber roller bracket to move along the bed chassis.

[0006] As a further technical solution, the bracket driving device includes a driving motor, a reducer, a transmission shaft, a pair of bevel gears and a pair of spur gears. The driving motor is connected to the reducer and is transmitted through a pair of bevel gears to drive the transmission shaft and the spur gears installed at both ends of the transmission shaft to rotate together. The spur gears are meshed with the racks installed on the bed chassis, thereby driving the front and rear brackets to move.

[0007] As a further technical solution, the chuck is supported by a chuck bracket, which includes a bracket and a pair of adjustable roller devices. The roller device is installed on the top of the bracket, and includes a roller seat and a roller installed on the roller seat, and the roller is used to support the chuck.

[0008] As a further technical solution, the supporting wheel device can move radially along the chuck to adjust the position of the supporting wheel.

[0009] As a further technical solution, the rubber roller bracket includes two, which are respectively installed on the front and rear axle ends of the rubber roller.

[0010] As a further technical solution, the bedside drive device is used to provide power for the workpiece to perform rotational motion, and is connected to a chuck device for clamping the workpiece via a universal coupling.

[0011] As a further technical solution, the top surface of the bed chassis is provided with guide rails parallel to each other, and the rubber roller bracket and the chuck bracket are both connected to the guide rails on the bed chassis.

[0012] In a second aspect, the present invention further provides a rubber roller winding machine, comprising the aforementioned weighable bed for the rubber roller winding machine.

[0013] The working principle of the present invention is:

[0014] During the gluing operation, the user first adjusts the position of the front and rear brackets in the weighable bed structure according to the size of the workpiece to be processed, so that the front and rear brackets respectively support the front and rear shaft head sections of the processed roller core. At this time, the weighing sensors installed on the front and rear brackets convert the gravity acting on the measured workpiece into a measurable output signal according to a certain proportion and enter the PLC. The industrial computer can directly read the weight of the roller core. When the gluing operation starts, the chuck drives the roller core to rotate under the drive of the bed head drive device, so that the gluing structure can press the rubber strip and spirally wind it on the roller core. The weighing sensor in the weighable bed structure can detect the weight change of the entire gluing process and transmit it to the industrial computer, so that the user can check the glue usage in real time. After the gluing is completed, the total weight obtained by the weighing sensor minus the weight of the roller core is the total glue usage, which can be read intuitively in the industrial computer, so that customers can have an intuitive understanding of the product glue usage information and provide a reference for the glue usage of the same or similar roller cores in the future.

[0015] The beneficial effects of the present invention are:

Through a newly designed rubber roller bracket, that is, a weighing sensor is designed on the rubber roller bracket, the weight of the roller core, the weight change during the glue coating process and the total glue consumption can be monitored, and the user can intuitively view the glue consumption information. It is particularly suitable for rubber roller products with complex roller core shapes, thick rubber coating layers, and difficult to accurately calculate the glue consumption. It is convenient for users to set glue coating parameters according to weight information and accurately fill in workpiece file information, which plays a certain guiding or reference role in the subsequent glue coating operations of the same or similar roller cores, liberates manpower to a certain extent, saves production energy, and reduces production costs.

[0017] 3.

The guide rail surface is flat and wide, with good load-bearing capacity, high rigidity, good wear resistance, simple structure and low manufacturing cost. The maximum diameter of the workpiece is ∮3500mm and the maximum load-bearing capacity is 70 tons, which meets the needs of some industries for large-tonnage rubber roller products.
