Description
Technical Field
[0001] The utility model relates to the technical field of tire lining laminating machines, in particular to an automatic width adjustment device for an anti-rubbing cloth pressing roller. Background Art
[0002] Anti-scratch cloth needs to be laminated on both sides of the tire tread, which is usually done using a laminating machine. The tire tread has a variety of widths, so when the laminating machine laminates treads of different specifications, the distance between the two rollers needs to be adjusted to accommodate the different specifications of the tire tread.
[0003] The existing adjustment method generally adopts manual adjustment, but manual adjustment requires repeated measurements, which increases the labor intensity of workers. Not only is the adjustment efficiency low, but the adjustment accuracy is also relatively low, which causes the quality of the tire tread belt produced to be unstable. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model provides an automatic adjustment device for the width of an anti-rubbing cloth pressure roller, comprising a frame, a width adjustment device is installed on the frame, and a liftable pressure roller assembly is fixed on the width adjustment device; the width adjustment device comprises a lead screw rotatably installed on the frame and a servo motor for controlling the forward and reverse rotation of the lead screw, the length direction of the lead screw is perpendicular to the conveying direction of the tread band; the lead screw is symmetrically arranged with a first lead screw thread and a second lead screw thread around the tread band as the center, the first lead screw thread and the second lead screw thread have opposite rotation directions and lead screw sliders are respectively screwed thereon, a guide rod parallel to the lead screw is installed on the frame, and the lead screw slider is slidably installed on the guide rod; the pressure roller assembly comprises a pressure roller frame and a pressure roller rotatably installed on the pressure roller frame, the pressure roller is located above the tread band and its rolling direction is consistent with the conveying direction of the tread band, and the pressure roller assembly is fixed on the lead screw slider through a lifting structure.
[0006] After adopting the above structure, by inputting the required width number into the control system of the servo motor, the servo motor will automatically adjust the number of turns required according to the set width, and drive the lead screw to rotate, and the two lead screw sliders on the lead screw move relative to or opposite to each other, so as to achieve precise adjustment of the distance between the two lead screw sliders; because a pressure roller assembly is installed on each lead screw slider, the distance between the two pressure roller assemblies can be adjusted. This automatic adjustment method avoids repeated measurements when workers manually adjust the pressure roller distance, reduces the labor intensity of workers, improves the adjustment efficiency, and ensures the adjustment accuracy, so that the quality of the tire tread belt produced is stable.
[0007] In order to prevent the long-term operation of the pressure roller assembly from causing deformation of the lead screw and the guide rod, a guide slider is provided on the top of the lead screw slider, and a slide rail for the guide slider to slide is provided on the frame.
[0008] In order to reduce the friction of the guide slider, the sliding friction is changed to rolling friction, so the guide slider is a guide wheel, and the wheel surface of the guide wheel cooperates with the slide rail.
[0009] In order to increase the stress points and avoid concentrated force on a single guide wheel, which may cause damage, two guide wheels are provided on the top of each lead screw slider.
[0010] In order to ensure balanced force and maximize the effectiveness of the guide slider, the guide slider is located directly above the pressure roller assembly.
[0011] In order to achieve the maximum guiding effect and avoid long-term force work that may cause the screw slider to tilt, the guide rod and guide slider are located on the upper and lower sides of the screw respectively.

[0014] In order to ensure the lifting stability, the lifting structure includes a cylinder fixed on the screw slider, and the cylinder is a double-rod cylinder.
[0015] After adopting the above technical solution, the beneficial effects of the utility model are:

DETAILED DESCRIPTION
[0021] The utility model is further described below in conjunction with the accompanying drawings.
[0022] The positions mentioned in this specification are based on the positions of the automatic adjustment device for the width of the anti-rubbing cloth roller of the utility model when it is working normally, and do not limit the positions during storage and transportation. They only represent relative position relationships, not absolute position relationships.
[0023] Embodiment 1:
[0024] like Figure 1 and Figure 2 As shown together, an automatic width adjustment device for an anti-rubbing cloth pressure roller comprises a frame 1, a width adjustment device 2 is mounted on the frame 1, and a liftable pressure roller assembly 3 is fixed on the width adjustment device 2.
[0025] The width adjustment device 2 includes a lead screw 21 rotatably mounted on the frame 1 and a servo motor for controlling the forward and reverse rotation of the lead screw 21. The length direction of the lead screw 21 is perpendicular to the conveying direction of the tread band 4 (in this embodiment, the servo motor is mounted at the bottom of the frame 1, not shown in the figure). A driving wheel is fixed on the output shaft of the servo motor, and one end of the lead screw 21 is connected to a driven wheel 22 through a coupling, and the driving wheel and the driven wheel 22 are connected through a belt 23. A clutch 24 is fixed to the other end of the axle of the driven wheel 22, which is a magnetic powder clutch in this embodiment. The forward and reverse rotation of the lead screw 21 is driven by the rotation of the servo motor.
[0026] The lead screw 21 is symmetrically provided with a first lead screw thread and a second lead screw thread with the tread band 4 as the center, the first lead screw thread and the second lead screw thread have opposite rotation directions and are respectively screwed with a lead screw slider 212. By the forward and reverse rotation of the lead screw 21, the two lead screw sliders 212 can run relative to or opposite to each other.
[0027] In order to guide the two lead screw sliders 212, a guide rod 25 parallel to the lead screw 21 is fixedly mounted on the frame 1, and the lead screw slider 212 is slidably mounted on the guide rod 25. The installation method is: a sliding hole is opened on the lead screw slider 212, a sliding sleeve is arranged in the sliding hole, and the sliding sleeve is slidably mounted on the guide rod 25.
[0028] In order to avoid the collision of two lead screw slide blocks 212, a limiting sleeve is provided at the middle position of the lead screw 21. In order to realize the intermediate support, an intermediate bearing seat 26 is also installed on the frame 1, and the limiting sleeve is rotatably mounted on the intermediate bearing seat 26.
[0029] The pressure roller assembly 3 includes a pressure roller frame 31 and a pressure roller 32 rotatably mounted on the pressure roller frame 31. The pressure roller 32 is located above the tread band 4 and its rolling direction is consistent with the conveying direction of the tread band 4. The pressure roller assembly 3 is fixed on the lead screw slider 212 through a lifting structure. The lifting and lowering of the lifting structure controls the pressure roller 32 to press on the tread band 4.
[0030] In this embodiment, the lifting structure includes a cylinder 41 fixed on the lead screw slider 212. In this embodiment, the cylinder is a double-rod cylinder. The output shaft of the cylinder 41 is vertically downward and fixed on the pressure roller frame 31. The lifting and lowering of the pressure roller frame 31 is controlled by the extension and contraction of the cylinder 41, so that the pressure roller 32 presses and fits the tread band 4 and the anti-friction cloth.
[0031] When it is necessary to adjust the spacing between the two pressure roller assemblies 3, the required width number is input into the control system of the servo motor. The servo motor will automatically adjust the number of revolutions required according to the set width, and drive the screw 21 to rotate. The two screw sliders 212 on the screw 21 move relative to or away from each other, thereby adjusting the spacing between the two screw sliders 212, and then adjusting the spacing between the two pressure roller assemblies 3.
[0032] Embodiment 2:
[0033] In the first embodiment, because the pressure roller assembly 3 exerts long-term pressure on the lead screw 21 and the guide rod 25, it is very easy to cause deformation of the lead screw 21 and the guide rod 25, so this embodiment is improved on the basis of the first embodiment.
[0034] A guide slider is provided on the top of the lead screw slider 212, and a slide rail 51 for the guide slider to slide is provided on the frame 1. The guide slider provides top support for the pressure roller assembly 3, thereby avoiding deformation of the lead screw 21 and the guide rod 25 under stress.
[0035] In order to achieve force on both sides, ensure the maximum guiding effect, and avoid the screw slider 212 from tilting, the guide rod 25 and the guide slider are respectively located on the upper and lower sides of the screw 21.
[0036] like Figure 3 As shown, in order to reduce the friction between the guide slider and the slide rail 51, the guide slider in this embodiment is a guide wheel 52, and the wheel surface of the guide wheel 52 cooperates with the slide rail 51, that is, the wheel surface of the guide wheel 52 is provided with a groove, and the groove is snapped on the slide rail 51, thereby realizing the guiding function of the guide wheel 52.
[0037] In order to increase the stress points and avoid the concentrated stress on the single guide wheel 52, two guide wheels 52 are provided on the top of each lead screw slider 212, and both guide wheels 52 are rollingly mounted on the slide rail 51. In order to avoid uneven stress and maximize the supporting effect of the guide slider, the guide slider is located directly above the pressure roller assembly 3.
[0038] The utility model discloses an automatic adjustment device for the width of an anti-rubbing cloth pressure roller, which solves the technical problems in the prior art of manually adjusting the width of the anti-rubbing cloth pressure roller, which results in high labor intensity for workers, low adjustment efficiency and low precision. The utility model adjusts the distance between the two pressure rollers by automatic adjustment, thereby reducing the labor intensity of workers, improving the adjustment efficiency and ensuring the adjustment precision, so that the quality of the tire tread band produced is stable.
[0039] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
