Description

Technical Field

[0001] The invention relates to the technical field of rubber roller coating, in particular to a numerically controlled medium-sized multifunctional rubber roller winding and coating mechanism. Background Art

[0002] The rubber roller winding and laminating machine is a very important equipment in the automatic production process of rubber rollers. With the improvement of the degree of automation, the demand for rubber rollers in the market is increasing, and the quality requirements for rubber rollers are also increasing. At present, the rubber laminating machines on the market have the following problems:

[0003] (1) Large multifunctional rubber coating machines occupy a large area and have high production costs. When coating small and medium-sized rollers, the cylinder mechanical arm has a large stroke, resulting in unstable operation and inflexible operation, which affects the production efficiency and even the quality of the rubber rollers.

[0004] (2) There are three types of coating on the surface of rubber rollers: flat coating, oblique coating and end coating. However, the coating integration of small and medium-sized coating machines is not high, which makes it difficult to meet the requirements of diversified production of rubber rollers. This affects the production efficiency of rubber rollers and increases labor costs. Moreover, for rubber rollers with thicker coating layers, the probability of coating defects caused by repeated flat coating will increase, which seriously affects the quality of rubber rollers.

[0005] (3) The position of the rubber strip is difficult to adjust. When applying glue flatly, the rubber strip may deviate from the center position of the rubber guide wheel during the transmission process; when applying glue obliquely or on the end surface, if the rubber strip cannot be adjusted to the position where the rubber pressing wheel is close to the rubber roller, the effect of applying glue will be affected, thereby affecting the normal use of the finished rubber roller.

[0006] (4) When the rubber strip is extruded and pressed on the rubber roller, there is a deviation between the actual rubber strip thickness and the theoretical rubber strip thickness due to elasticity. At this time, if the various rubber packaging parameters are calculated entirely by theoretical values, it is difficult to control the product process quality, resulting in a waste of raw materials. Summary of the invention

[0007] Aiming at the deficiencies of the prior art, the present invention proposes a numerically controlled medium-sized multifunctional rubber roller winding and covering mechanism.

[0008] The technical solution adopted by the present invention to solve its technical problem is:

[0009] The invention discloses a numerically controlled medium-sized multifunctional rubber roller winding and covering mechanism, comprising a frame, a first workbench, a second workbench, a gear box, a rubber strip thickness detection device, a rubber bag thickness detection device, a temperature measuring device, a speed regulating device, a tension strapping device, a deviation correction structure, a flat / oblique / end bag integrated structure, and a control box;

[0010] The first workbench is connected to the frame through a linear guide rail, and is driven by a servo motor and a high-precision ball screw to enable the first workbench to complete a feeding movement approaching or moving away from the workpiece in a direction perpendicular to the axis of the workpiece; the second workbench is connected to the first workbench through a linear guide rail, and is driven by the extension and retraction of a self-locking cylinder to also complete a feeding movement in a direction perpendicular to the axis of the workpiece; the gear box is fixed to the front end of the second workbench through a thread, and the flat / oblique / end package integrated structure is locked on the rotating shaft of the gear box, and the first workbench and the second workbench complete the feeding movement under the joint action of the first workbench and the second workbench. Flat coating, oblique coating and end surface coating of the roller core; the rubber strip thickness measuring device and the rubber coating thickness detection device can move forward and backward with the second workbench and the first workbench respectively, and are used for real-time measurement of the thickness of the rubber strip and the coating, and compare the detected thickness with the theoretical thickness, and adjust the speed of the servo motor to make the measured data consistent with the theoretical data to achieve the purpose of closed-loop control; the control box is fixed on the first workbench, including a control system, an industrial-specific integrated industrial computer, buttons and communication modules, which completes visual closed-loop control of the entire coating process while also providing a basic platform for intelligent manufacturing and interconnection.

[0011] Furthermore, the gearbox includes a box body, a pair of bevel gears, an encoder, upper and lower flanges and an output shaft. Driven by a brake motor installed on the second workbench, the flat / oblique / end package integrated structure locked on the gearbox is driven to rotate to meet different coating function requirements.

[0012] The flat / oblique / end-wrapping integrated structure includes a bidirectional cylinder, a pair of rubber pressing wheel groups, a winding plate and a rubber guide wheel group. The bidirectional cylinder is used on the one hand to utilize the pressure of the cylinder to press the rubber strip against the end face of the roller core during end wrapping, and on the other hand to push the rubber pressing wheel groups on both sides of the winding plate to cover the end face with glue during end wrapping, so as to ensure that the end faces of both sides of the rubber roller are completely wrapped without changing the direction of the rubber roller.

[0013] The speed regulating device, tension strapping device and deviation correction structure are all fixed on the frame. The speed regulating device is connected to the encoder to sense the conveying speed of the rubber strip and then adjust the extrusion speed of the extruder; the tension strapping device senses the tension of the strapping through the pressure sensor, and adjusts the tightening force to achieve controllable strapping of the rubber roller after rubber coating, thereby improving the vulcanization quality of the rubber roller; the deviation correction structure includes a joint bearing, a deviation correction wheel, a top shaft, a hand wheel, and a pressure cover. The joint bearing is installed on the front panel of the bracket, and the deviation correction wheel is connected to the frame through the joint bearing. A groove is formed under the shaft of the deviation correction wheel, and the groove cooperates with the upper end of the top shaft. A hand wheel is installed at the lower end of the top shaft. The tilt direction of the deviation correction wheel is controlled by rotating the hand wheel to complete the adjustment of the rubber strip position to meet the requirements of flat coating, oblique coating and end coating for the rubber strip position.

[0014] The rubber coating thickness detection device is fixed on the control box through a bracket, and includes a thickness measuring box, an ultra-thin cylinder, a double-rod cylinder, a steering reducer, a laser detector, a cylinder plate, a micro guide rail, an L bracket, a hand wheel and a circular slide rail. The circular rail and the ultra-thin cylinder are fixed in the thickness measuring box, and the circular guide rail slider is connected to the cylinder plate. The double-rod cylinder is fixed on the cylinder plate and is controlled to move by the ultra-thin cylinder. The double-rod cylinder is equipped with a steering reducer, and a laser detector is installed at the front end of the steering reducer. A hand wheel is installed at the upper end. The laser detector can be controlled to rotate by rotating the hand wheel to meet the measurement requirements of rubber rollers of different diameters. At the same time, the measurement of the rubber roller before, after and during the rubber coating process can be completed by adjusting the positions of the two cylinders; the micro guide rail is installed at the upper end of the cylinder plate, the guide rail slider is connected to the L bracket, and the other side of the L bracket is connected to the double-rod cylinder rod. When the double-rod cylinder moves with the steering reducer equipped with the laser detector, the L bracket pulls the cylinder rod to avoid the measurement error caused by the sagging and bending of the cylinder rod due to weight reasons.

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

[0016] The present invention adopts an upper and lower movable working platform in structure, which reduces the footprint of the equipment to the maximum extent, realizes high integration and miniaturization, is flexible in operation and has greatly improved stability, and can realize stable gluing of small and medium-sized rubber rollers below 1 meter; the brake motor drives the rubber pressing wheel to rotate arbitrarily, and can complete flat gluing, oblique gluing and end gluing of the workpiece according to needs; the deviation correction device can tilt the deviation correction wheel to a certain angle to adjust the position of the rubber strip, so that the rubber strip is in the center position when flat wrapping, and the rubber strip is adjusted to the edge of the rubber pressing wheel when oblique gluing and end gluing to meet the gluing requirements; because rubber is elastic The thickness of the rubber strip will change when the rubber pressing wheel presses it onto the rubber roller. The rubber coating will have a large deviation if it relies solely on theoretical data. The present invention is equipped with a rubber strip thickness measuring device and a rubber coating thickness measuring device. The rubber coating thickness measuring device can measure before, after and during rubber coating with the cooperation of double cylinders. The measurement results are fed back to a professional system for comparison with theoretical data, and then the corresponding speed is adjusted to make the actual data as close to the theoretical data as possible, so as to realize controllable closed-loop rubber coating in the rubber coating process, which greatly saves raw materials. The controllable tension strapping function after the rubber coating is completed also greatly improves the quality of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] like Figure 8As shown, the rubber strip thickness detection device disclosed in this embodiment includes a bracket 10-1, a laser measuring instrument 10-2, a connecting frame 10-3, and two rubber guide wheels 10-4. The bracket 10-1 is fixed to the connecting frame 10-3 by fasteners, and the connecting frame 10-3 is connected to the frame 1; the laser measuring instrument 10-2 is fixed to the bracket 10-1, and the rubber strip is transmitted through two rubber guide wheels 10-4. The two rubber guide wheels 10-4 are arranged up and down, one is located below the laser measuring instrument 10-2, and the other is located on one side of the laser measuring instrument 10-2; and the center distance between the two rubber guide wheels is equal to the diameter of the rubber guide wheels, thereby ensuring that the rubber strip is vertically transmitted to the second rubber guide wheel 10-4 (located on one side of the laser measuring instrument 10-2), ensuring that the laser beam is perpendicular to the rubber surface, thereby ensuring the accuracy of the measurement.

[0037] like Fig. 9 , Fig.10 As shown, the flat / oblique / end-wrapping integrated structure disclosed in this embodiment includes a wrapping plate 9-1, two pairs of rubber pressing wheel groups 9-2, guide wheels 9-3, bidirectional cylinders 9-4 and sliders 9-5. The two pairs of rubber pressing wheel groups 9-2 are fixed on two sliders 9-5, and the two sliders 9-5 can move along the slide groove of the wrapping plate 9-1 under the push of the corresponding bidirectional cylinders 9-4. When flat / oblique wrapping, the rubber pressing wheel group 9-2 is driven by the brake motor 13 to make the workpiece 20 parallel to the axis or at a certain angle for glue coating. When end wrapping, the brake motor 13 drives the rubber pressing wheel group 9-2 to rotate to a position perpendicular to the axis of the roller core, and the rubber strip is pressed against the end face by the bidirectional cylinder 9-4, and then the end face is coated with rubber by radial movement along the end face of the roller core. When wrapping the other end face, the bidirectional cylinder 9-4 pushes the rubber pressing wheel on the other side to press the rubber strip against the end face, thereby ensuring the complete coating of the end faces at both ends without replacing the workpiece.

[0038] The working principle of the present invention is:

[0039] The rubber strip extruded by the extruder passes through the rubber guide wheel 2 and enters the deviation correction device 3, and then is transmitted to the rubber pressing wheel group 9-2 through the rubber guide wheel group, the speed regulating device, and the rubber strip thickness detection device, and then is wound on the rubber roller.

[0040] When flat coating, the self-locking cylinder 14 pushes the flat / oblique / end-wrapped integrated structure to move, so that the rubber pressing wheel group in the flat / oblique / end-wrapped integrated structure reciprocates parallel to the roller core axis;

[0041] When the glue is applied obliquely, the self-locking cylinder 14 pushes the flat / oblique / end-wrapped integrated structure to move. According to the thickness of the glue, the displacement sent by the industrial computer, PLC, and sensor causes the glue pressing wheel to rotate a certain angle relative to the axis of the roller core to apply glue, so that after the flat glue application of the bottom layer is completed, it will continuously transition to the oblique glue application. The whole process is automatically completed by the industrial computer according to the parameters input in real time;

[0042] When the end face is coated with glue, first lock the self-locking cylinder 14, then rotate the glue pressing wheel group 9-2 to a position perpendicular to the axis of the roller core, use the bidirectional cylinder 9-4 to press the rubber strip on the end face of the roller core, and finally drive the servo motor to drive the second workbench fixed with the self-locking cylinder 14 to move radially along the end face of the roller core by the ball screw, so as to complete the end coating function. When coating the end faces of both sides of the roller, different glue pressing wheels on both sides of the bidirectional cylinder 9-4 are used respectively, so as to complete the complete coating of the end face without adjusting the direction of the rubber roller.

[0043] During the transmission process of the rubber strip, the correction device adjusts the position of the rubber strip according to the position requirements, the rubber strip thickness detection device measures the actual rubber strip thickness in real time, and the rubber bag thickness detection device measures the rubber bag thickness. These data are transmitted to the industrial computer for comparison with the theoretical data, and the extrusion speed of the extruder is adjusted through the speed regulation device according to the comparison results, so as to achieve closed-loop control of the rubber bag thickness.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
