Description

Technical Field

[0001] The present invention relates to the technical field of rubber roller manufacturing, and in particular to a large-scale multifunctional winding rubber coating mechanism. Background Art

[0002] With the development of science and technology, rubber rollers are applied in more and more fields due to their excellent performance. While the demand for them is increasing day by day, the market also has an increasing demand for large-sized rubber rollers and special-shaped rubber rollers.

[0003] In the patent with the patent number (201410038604.5), a large-scale full-functional rubber roller winding and covering machine is disclosed, which has the functions of flat rubber coating, inclined rubber coating and end face rubber coating at the same time. However, the following problems still exist in this winding machine:

[0004] 1. The rubber coating diameter range of this winding machine is 1000 - 2500 mm, which cannot meet the size requirements of some large-sized rubber rollers.

[0005] 2. When the winding machine performs inclined rubber coating and end face rubber coating, a deviation rectifying device is needed to adjust the position of the rubber strip. However, this winding machine is only equipped with a simple manual deviation rectifying structure, and it is necessary to manually roughly adjust the position of the rubber strip according to the rotation angle of the rubber pressing wheel, which cannot meet the needs of some special-shaped rubber rollers that often change the rotation angle of the rubber pressing wheel, thus reducing the efficiency.

[0006] 3. This winding machine only has a simple single-position rubber coating thickness measuring device, which cannot complete the real-time measurement of the thickness before / after / during the rubber strip and rubber surface coating, and thus cannot complete the closed-loop control and real-time adjustment. Moreover, the thickness measurement of this structure uses a laser rangefinder, which measures the distance to the target by laser. It is necessary to assist the device to tell the change of the distance. If measuring rubber rollers with a large diameter range, it is necessary to lengthen the telescopic rod and increase the pressing cylinder, and at the same time, the entire auxiliary structure needs to be strengthened to ensure its stability and the accuracy of the measurement, which increases the manufacturing cost and affects the appearance of the structure, and is not conducive to the operation of the rubber coating operation. Summary of the Invention

[0007] In order to solve the deficiencies of the existing technology, the present invention discloses a large-scale multifunctional winding rubber coating mechanism, which can realize multifunctional numerical control winding rubber coating for large-sized rubber rollers with a diameter range of ∮500 mm to ∮3500 mm and unlimited length dimensions.

[0008] The present invention is achieved through the following technical solutions:

[0009] A large-scale multi-functional winding and rubber coating mechanism, including a frame, on which a first slide plate mechanism is provided. The first slide plate mechanism can complete the feeding movement of approaching or departing from the roll core along a direction perpendicular to the axis of the roll core. A second slide plate mechanism is provided on the first slide plate structure. The sliding direction of the second slide plate mechanism is the same as that of the first slide plate structure, and a rubber coating mechanism is installed at the end of the second slide plate mechanism.

[0010] As a further technical solution, the first slide plate mechanism includes a first slide plate, a first linear guide rail and a servo drive. The first slide plate is connected to the frame through the first linear guide rail, and the servo drive is fixed on the frame. The servo drive drives the first slide plate through a gear-rack transmission mechanism.

[0011] As a further technical solution, the second slide plate mechanism includes a second slide plate, a second linear guide rail and a self-locking cylinder. The second slide plate is installed on the outside of the first slide plate mechanism through the linear guide rail, and the self-locking cylinder pushes the second slide plate to make a feeding movement along a direction perpendicular to the axis of the roll core.

[0012] As a further technical solution, it further includes a rubber coating thickness measuring device, which includes a base. The base is installed and fixed on the frame, and a second drive is fixed on the base. The top of the base is connected to a thickness measuring cantilever through an axial linear guide rail, and the second drive drives the thickness measuring cantilever through an axial ball screw pair. A radial ball screw pair and a radial linear guide rail are installed at the upper end of the thickness measuring cantilever, and the second drive drives a laser displacement sensor to move along the radial linear guide rail through the radial ball screw pair.

[0013] As a further technical solution, the thickness measuring cantilever is a right triangle, and the radial ball screw pair and the radial linear guide rail are installed on the inclined arm of the right triangle.

[0014] As a further technical solution, the rubber coating mechanism includes a servo drive, a rubber coating wheel and two rubber guiding wheels. Driven by the servo drive, the rubber coating wheel can rotate at any angle to perform flat rubber coating, inclined rubber coating and end face rubber coating on the rubber roller, and the two rubber guiding wheels are used to transmit the rubber strip on the one hand.

[0015] As a further technical solution, the center distance between one of the rubber guiding wheels and the rubber coating wheel is exactly equal to the sum of the radii of the two wheels.

[0016] As a further technical solution, it further includes a deviation rectifying device, which is installed at the lower end of the second slide plate mechanism and can move together with the second slide plate mechanism, and is used to adjust the position of the rubber strip to meet the requirements of different positions of the rubber strip during flat rubber coating, inclined rubber coating and end face rubber coating.

[0017] As a further technical solution, the deviation rectifying device includes an adjusting plate, a deviation rectifying wheel, a screw jack and a servo motor. The adjusting plate is fixedly installed at the lower end of the second slide plate mechanism. The screw jack is fixed on the adjusting plate and is driven by the servo motor to lift the screw jack. The wheel axle of the deviation rectifying wheel is connected to the screw jack through a hinge.

[0018] As a further technical solution, it further includes an operation box which is fixed on the frame through a chassis cantilever assembly.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The main structure of the present invention adopts a side double-slide plate structure (the first slide plate mechanism and the second slide plate mechanism). While ensuring strength and stability, it maximally saves floor space and can achieve flat rubber coating, inclined rubber coating and end face rubber coating for large rubber rollers with a diameter ranging from ∮500mm to ∮3500mm.

[0021] 2. The deviation rectifying device in the present invention includes an adjusting plate, a deviation rectifying wheel, a screw jack and a servo motor. The adjusting plate is fixedly installed at the lower end of the second slide plate mechanism. The screw jack is fixed on the adjusting plate and is driven by the servo motor to lift the screw jack. The wheel axle of the deviation rectifying wheel is connected to the screw jack through a hinge. The deviation rectification adopts servo control, which can complete the automatic rubber coating of special-shaped rubber rollers, maximally reducing the labor intensity and improving the production efficiency.

[0022] 3. The rubber coating thickness measuring device in the present invention is ingeniously designed. The axial ball screw is driven to rotate, thereby driving the thickness measuring cantilever to move axially along the workpiece for multi-position measurement before, after and during the rubber coating of the workpiece. A radial ball screw drive is installed at the upper end of the thickness measuring cantilever. The slider of the radial linear guide rail is also fixed at the front end of the thickness measuring cantilever. One end of the linear guide rail is fixed by a sensor seat with a laser displacement sensor, and the other end is connected to the radial ball screw nut. In this way, under the drive of the radial ball screw drive, the linear guide rail can move radially along the workpiece, thereby driving the laser displacement sensor to move to adjust the position of the laser displacement sensor so that the currently measured rubber coating radius is within the measurement range of the sensor to ensure its measurement accuracy, especially suitable for large rubber rollers with a total rubber coating radius greater than the measurement radius of the laser displacement sensor.

[0023] 4. The multi-functional winding and rubber coating mechanism is also equipped with a rubber strip thickness measuring device and a multi-position rubber coating thickness measuring device. The laser displacement sensor is used for measurement, which is convenient to install and accurate in measurement. The measured data is fed back to the industrial control computer for comparison with the theoretical data. The rotational speed of the servo motor is adjusted according to the comparison result to make the rubber coating thickness consistent, realizing the accuracy and reliability of the rubber coating thickness, improving the degree of automation, saving raw materials to the greatest extent, and laying a foundation for the subsequent intelligent construction.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figure 1 , Figure 2 , Figure 3 shown, the whole of the present invention includes a rubber pressing mechanism 1, a small slide plate mechanism 2, a rubber coating thickness measuring device 3, an operation box 4, a rubber strip temperature measuring device 5, a cylinder 6, a large slide plate mechanism 7, a guide wheel group 8, a speed regulating device 9, a frame 10, a deviation rectifying device 11, and a rubber strip temperature measuring device 12; the frame 10 is used for installing and fixing the whole winding mechanism.

[0032] The large slide plate mechanism 7 (corresponding to the first slide plate mechanism mentioned above) is connected to the frame 10 through a large slide plate linear guide 7-1. The large slide plate servo drive 7-3 is fixed to the frame 10 by screws. A rack 7-2 is installed in the middle of the large slide plate mechanism 7, forming a gear-rack transmission mechanism with the gear installed on the output shaft of the large slide plate servo drive 7-3. Driven by the servo drive 7-3, the large slide plate mechanism 7 can complete the feeding movement of approaching or moving away from the roller core in a direction perpendicular to the axis of the roller core.

[0033] The small slide plate mechanism 2 (corresponding to the second slide plate mechanism mentioned above) is installed on the outside of the large slide plate mechanism 7 through a small slide plate linear guide 2-1, and can also make a feeding movement in a direction perpendicular to the axis of the roller core under the push of the self-locking cylinder 6, and drive the rubber pressing mechanism 1 installed at the front end of the small slide plate mechanism 2 to move together, which is convenient for pressing the rubber strip tightly on the roller core during rubber coating. The main structure of this embodiment adopts a side double-slide plate structure (the first slide plate mechanism and the second slide plate mechanism), which saves the floor space to the greatest extent while ensuring strength and stability, and can realize flat rubber coating, inclined rubber coating, and end face rubber coating for large rubber rollers with a diameter of ∮500mm to ∮3500mm.

[0034] The rubber pressing mechanism 1 includes a rotating shaft 1-1, a servo drive device 1-2, a fixed seat 1-3, a connecting block 1-4, a rubber pressing wheel 1-5, a winding plate 1-6 and a guide wheel 1-7. The fixed seat 1-3 is fixed on the cross slide mechanism 2 by screws. The servo drive device 1-2 is fixed on the upper end of the fixed seat 1-3. The rotating shaft 1-1 passes through the speed reducer of the servo drive device 1-2 and is connected to the fixed seat 1-3 through a bearing. A connecting block 1-4 is installed at the lower end of the rotating shaft 1-1. The winding plates 1-6 are respectively fixed at both ends of the connecting block 1-4 by screws. The rubber pressing wheel 1-5 and two guide wheels 1-7 are installed on the winding plate 1-6. Driven by the servo drive device 1-2, the rotating shaft 1-1 drives the connecting block 1-4 and the winding plate 1-6 installed on the connecting block 1-4 to rotate, and then drives the rubber pressing wheel 1-5 to rotate, so as to complete the operations of flat rubber covering, inclined rubber covering and end face rubber covering of the rubber roller.

[0035] Further, the two guide wheels 1-7 are used to transmit the rubber strip on one hand. The center distance between one of the guide wheels and the center of the rubber pressing wheel is exactly equal to the sum of the radii of the two wheels, so that the rubber strip thickness measuring device installed inside the rubber pressing mechanism can emit laser pulses along the cross section of the rubber strip, thereby ensuring the accuracy of the measured rubber strip thickness.

[0036] Further, the rubber strip temperature measuring device 12 is installed on the connecting block 1-4 and includes a laser displacement sensor and a mounting seat. In order to ensure the accuracy of the measurement, that is, the measured thickness is the thickness of the positive cross section of the rubber strip, the center distance between the guide wheel 1-7 at the upper end of the rubber pressing mechanism 1 and the rubber pressing wheel 1-5 is equal to the sum of the radii of the two wheels, so that the rubber strip can be horizontally conducted between the two wheels.

[0037] Further, the rubber covering thickness measuring device 3 is installed at the top of the frame 10 and is used for real-time measurement of the rubber covering thickness, and transmits the measured data to the system for comparison with the actual data. The system recalculates the overlap amount according to the rubber strip thickness measured by the rubber strip thickness detection device 12, and then adjusts the traveling speed of the trolley. When the rubber covering thickness measuring device 3 measures the rubber covering thickness, first input the required rubber covering thickness on the operating system interface, and zero it when the detection element measurement point reaches the roll core. At this time, the currently displayed detection thickness is zero. When starting to apply rubber, the detection point is in the middle position of the rubber covering wheel. When the detected thickness reaches the set thickness, the trolley servo motor starts to rotate at the set speed. When applying rubber, the rubber covering thickness measuring device 3 can move left and right along the workpiece to measure the thickness before and after rubber covering, and transmit the measured thickness to the system for comparison with the set thickness. If the measured value is greater than the set value, the system controls the trolley servo motor to accelerate through calculation. If the measured value is less than the set value, the system makes the servo motor decelerate through calculation to make the rubber covering thickness consistent, achieving the purpose of closed-loop control.

[0038] Further, the tape thickness measuring device and the rubber coating thickness measuring device in this embodiment both use a laser displacement sensor for thickness measurement, which can accurately and non-contact measure the changes in the position, displacement, etc. of the object to be measured, and the measurement accuracy reaches 1um.

[0039] Further, the tape temperature measuring device 5 and the guide group 8 are both connected to the T-shaped chute on the large slide plate mechanism 7 through T-shaped nuts and can move along the chute. The tape temperature measuring device 5 monitors the temperature of the tape through an optoelectronic temperature sensor, which is convenient for adjusting the temperature control device according to requirements. The guide group 8 provides guidance for the running direction of the tape. The speed regulating device 9 is connected to the encoder and is installed and fixed on the frame 10, which can sense the conveying speed of the tape and then adjust the extrusion speed of the extruder. The deviation rectifying device 11 is installed at the lower end of the small slide plate mechanism 2 and can move together with the slide plate 2, and is used to adjust the position of the tape to meet the requirements of different positions of the tape during flat rubber coating, inclined rubber coating and end face rubber coating. The operation box 4 is fixed on the frame through the chassis cantilever assembly, and includes a control system, an industrial special integrated industrial control computer, buttons and a communication module, which provides a visual closed-loop control for the entire rubber coating process and also provides a basic platform for intelligent manufacturing and interconnection.

[0040] As Figure 4As shown in the figure, the rubber coating thickness measuring device 3 includes a thickness measuring base 3-1, a laser displacement sensor 3-2, a sensor seat 3-3, a radial linear guide 3-4, a radial ball screw nut 3-5, a radial ball screw 3-6, a radial ball screw drive 3-7, a thickness measuring cantilever 3-8, an axial ball screw drive 3-9, an axial ball screw nut 3-10, an axial ball screw 3-11, and an axial linear guide 3-12. The thickness measuring base 3-1 is fixedly installed on the frame 10 by screws. The axial ball screw drive 3-9 is fixedly installed on the thickness measuring base 3-1. The upper end of the thickness measuring base 3-1 is connected to the thickness measuring cantilever 3-8 through the axial linear guide 3-12. The axial ball screw nut 3-10 is fixed on the thickness measuring cantilever 3-8 by screws. In this way, by driving the axial ball screw 3-11 to rotate through the axial ball screw drive 3-9, the thickness measuring cantilever 3-8 can be driven to move along the axial direction of the workpiece, so as to complete multi-position measurement before, after, and during the rubber coating process of the workpiece. A radial ball screw drive 3-7 is installed at the upper end of the thickness measuring cantilever 3-8. The slider of the radial linear guide 3-4 is also fixed at the front end of the thickness measuring cantilever 3-8. One end of the guide rail of the linear guide 3-4 is fixed with the laser displacement sensor 3-2 through the sensor seat 3-3, and the other end is connected to the radial ball screw nut 3-5. In this way, under the drive of the radial ball screw drive 3-7, the linear guide 3-4 can move along the radial direction of the workpiece, and then drive the laser displacement sensor 3-2 to move, so as to adjust the position of the laser displacement sensor to make the currently measured rubber coating radius within the measurement range of the sensor, so as to ensure its measurement accuracy, especially suitable for large rubber rollers with a total rubber coating radius greater than the measurement radius of the laser displacement sensor.

[0041] As Figure 2 shown, the deviation rectifying device 11 includes an adjusting plate 11-1, a deviation rectifying wheel 11-2, a screw jack 11-3, and a servo motor 11-4. The adjusting plate 11-1 is fixedly installed at the lower end of the small slide plate mechanism 2. A long strip hole is opened on it so that the position of the deviation rectifying wheel 11-2 can be adjusted by adjusting the position of the adjusting plate 11-1. The screw jack 11-3 is fixed on the back of the adjusting plate 11-1 and is driven by the servo motor 11-4 to lift the screw jack 11-3. The axle of the deviation rectifying wheel 11-2 is connected to the screw jack 11-3 through a hinge. In this way, under the drive of the servo motor 11-4, the screw jack 11-3 can drive the deviation rectifying wheel 11-2 to swing up and down, so as to complete the adjustment of the position of the rubber strip. The servo drive 11-4 of the upper deviation rectifying device 4 is linked with the servo drive device 1-2 of the rubber pressing mechanism 1, so that when the rubber pressing wheel swings, the deviation rectifying wheel swings by a certain angle, which is convenient for frequently changing the rotation angle of the rubber pressing wheel when covering special-shaped rubber rollers.

[0042] The working principle of the present invention is:

[0043] After the rubber strip enters the multi-functional winding mechanism, it passes through the guide wheel group, rubber strip temperature measuring device, speed regulating device, deviation rectifying device, and rubber strip thickness measuring device and then enters the rubber pressing mechanism. Then, under the push of the air cylinder, the rubber strip is extruded and wound around the rotating workpiece by the rubber pressing structure. During the entire rubber coating process, the guide wheel group provides guidance for the movement of the rubber strip, and the rubber strip temperature measuring device measures the temperature of the rubber strip to ensure that the temperature of the rubber strip is within a suitable temperature range. If the measured temperature is higher or lower than the set temperature range, the system will give an alarm prompt and adjust the temperature of the temperature control device. The speed regulating device senses the conveying speed of the rubber strip and then adjusts the extrusion speed of the extruder to prevent the rubber strip from sagging due to too fast extrusion or being tightened due to too slow extrusion. The rubber pressing device rotates a certain angle under the control of the servo motor to complete the flat rubber coating, inclined rubber coating, and end face rubber coating of the roller core. The deviation rectifying device adjusts the position of the rubber strip according to the position requirements under the control of the servo motor. For example, during inclined wrapping or end face rubber coating, the rubber strip needs to be adjusted to one end of the rubber pressing wheel. When wrapping different end faces or with different rubber coating directions, the rubber strip needs to be adjusted to different ends of the rubber pressing wheel. Here, the rubber pressing device and the deviation rectifying device both adopt servo drive and are linked, that is, when the rubber pressing wheel rotates, the deviation rectifying wheel also swings, which is convenient for adjusting the position of the rubber strip accordingly when the rubber pressing wheel needs to change different angles frequently when wrapping special-shaped rubber rollers.

[0044] During the transmission of the rubber strip, the actual thickness of the rubber strip is measured in real time by the rubber strip thickness detection device, and the measured data is transmitted to the system for comparison with the actual data. The overlap amount is calculated based on the comparison result, and then the running speed is adjusted. The rubber coating thickness measuring device measures the rubber coating thickness at different positions. When measuring the rubber coating thickness, first enter the required rubber coating thickness on the operation interface, and then zero it when the detection element measurement point reaches the roller core. At this time, the currently displayed detection thickness is zero. When starting to apply rubber coating, the detection point is at the middle position of the rubber coating wheel. After detecting that the thickness reaches the set thickness, the servo motor starts to rotate at the set speed. During rubber coating, the rubber coating thickness measuring device moves left and right under the drive of the axial ball screw drive mechanism to measure the thickness before and after rubber coating, and transmits the measured thickness to the system for comparison with the set thickness. If the measured value is greater than the set value, the system controls the servo motor to accelerate through calculation; if the measured value is less than the set value, the system makes the servo motor decelerate through calculation to make the rubber coating thickness consistent, achieving the purpose of closed-loop control. When wrapping a large-diameter rubber roller, if the measured radius is greater than the measurement radius of the laser displacement sensor of the thickness measuring device, the rubber coating thickness measuring device drives the laser displacement sensor to move along the radial direction of the workpiece under the drive of the radial ball screw drive mechanism to adjust the measurement range of the rubber roller to ensure the measurement accuracy. The control box provides an automatic and visual closed-loop control for the entire rubber coating process and also provides a basic platform for intelligent manufacturing and interconnection.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
