Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of puncture-proof tire production, and particularly relates to a production device for puncture-proof tire production and a use method thereof. BACKGROUND

[0002] At present, tire production has gradually entered the era of full automation, and tire production raw materials are transported by a six-axis robot to a crushing tank for crushing and mixing, and then the rubber particles are automatically weighed and proportioned, and then the small materials are transported to a mixing mill together with synthetic rubber for mixing and extrusion, and the extruded rubber sheet will be used to make the tread, sidewall and inner liner, which are the most worn and punctured areas of the puncture-proof tire in the future use, so the tread, sidewall and inner liner need to be sampled, weighed, anti-worn and punctured after being extruded.

[0003] The puncture test is a key link in the production process and production equipment of the puncture-proof tire, and the existing puncture test has a relatively low simulation degree in actual use, and generally only a plurality of or a single part of the sample is punctured, and some factories that do not achieve automatic testing need to manually observe the puncture effect of the puncture object on the tread in the test room to determine whether the puncture-proof performance of the tread meets the standard, and the above detection methods cannot well reflect the real puncture-proof performance of the tire, and thus improvement is needed. SUMMARY

[0004] The purpose of the present application is to provide a production device for puncture-proof tire production and a use method thereof to solve the problems in the background.

[0005] In order to achieve the above purpose, the present application provides the following technical scheme:

[0006] The production device for puncture-proof tire production and the use method thereof comprise a sliding device and a control and display module, a hydraulic rod is fixedly installed at the bottom of the sliding device, a fixed frame is fixedly connected to the output end of the hydraulic rod, a rotating drum is movably installed on the inner side of the fixed frame, and a motor is fixedly installed on the outer side of the fixed frame, the motor is in transmission connection with the rotating drum, an elastic mechanism is installed on the rotating drum, and a sliding block and a puncture needle are connected to the inner and outer ends of the elastic mechanism, respectively.

[0007] The inner side of the rotating drum comprises two layers of outer and inner plate surfaces, and an intermediate slide is arranged between the outer and inner plate surfaces, the sliding block is slidably installed on the inner side of the intermediate slide, a tension and pressure sensor is arranged on the inner side of the inner plate surface, a pressure arm is hingedly connected to the top of the inner plate surface, the inner end of the pressure arm is located on the top of the sensing side of the tension and pressure sensor, the outer end of the pressure arm is in abutment with the inclined surface of the sliding block, and the tension and pressure sensor is electrically connected with the control and display module.

[0008] The inner end of the sliding block is provided with an inclined surface with an inclined angle of 45 degrees, the outer end of the sliding block is a vertical plane and is in contact with the inner end of the elastic mechanism, the inclined surface of the sliding block pushes the contact end of the pressing arm to rise, and the other end of the pressing arm inclines downward and presses the top of the tension and pressure sensor.

[0009] The top of the inner side of the intermediate slide is provided with a cushion layer, the sliding block is above the cushion layer of the intermediate slide and can slide up and down along the cushion layer, and the cushion layer connects the outer layer plate and the inner layer plate. The cushion layer first enhances the strength of the outer layer plate and the inner layer plate, and provides a sliding support for the sliding block, plays a limiting role, and prevents the sliding block from slipping off.

[0010] The elastic mechanism includes a fixed cylinder, a spring, a fixed plate, a movable rod and a clamping plate. The movable rod is sleeved in the inner cavity of the fixed cylinder, the clamping plate is arranged on the inner cavity wall of the fixed cylinder, the fixed plate is arranged on the outer surface of the movable rod, the spring is sleeved on the surface of the movable rod and elastically supported between the fixed plate and the clamping plate, the inner end of the elastic mechanism is the inner end of the movable rod in contact with the sliding block, the outer end of the movable rod is fixedly connected with a puncture needle, and the fixed cylinder is fixedly installed on the outer shell of the rotating drum. When the tip of the puncture needle is supported, the spring will first contract, and then apply pressure to the sliding block. After the puncture needle penetrates, the spring will further push the puncture needle due to the elastic force, so as to realize the rapid separation of the movable rod and the sliding block.

[0011] The elastic mechanism is equally arranged on the outer shell of the rotating drum. The sliding block and the pressing arm in the inner cavity of the rotating drum are equally arranged in eight groups, and each sliding block is in contact with the inner end of one elastic mechanism. This is to rotate the rotating drum under the control of the motor, so that the eight puncture needles can rotate to puncture the detected object, improving the detection efficiency.

[0012] The contact end of the pressing arm and the inclined surface of the sliding block is provided with an arc surface. The length of the force arm of the contact end of the pressing arm and the sliding block is less than that of the contact end of the pressing arm and the tension and pressure sensor. The advantage of this arrangement is that it can save the internal space of the rotating drum, relatively reduce the diameter of the rotating drum, concentrate the pressing arm to the middle of the inner cavity of the rotating drum, and when the pressing arm and the sliding block are in contact and are supported by a large force, the pressure applied to the top of the tension and pressure sensor by the longer end will be relatively small, preventing uncontrolled pressure from damaging the tension and pressure sensor.

[0013] The puncture needle is provided below the conveyor. The conveyor is provided with a roller on which a detected tire tread, sidewall or inner liner is laid. The conveyor is used for automatic transfer and receiving of the detected object. During the detection process, the conveyor is not working. Only when the detected object is loaded or unloaded, the conveyor works to transfer the detected object.

[0014] The upper surface of the roller of the conveyor is provided with a groove, the tire tread or the tire side or the inner liner covers the groove, the groove is located directly below the puncture needle, the groove provides a space for the puncture needle to penetrate, and the tip of the puncture needle provides a recessed space for the tested object when the tested object is recessed.

[0015] The application also provides a method for using the production equipment for the puncture-proof tire production, which comprises the following steps: the tire tread, the tire side or the inner liner is conveyed from the extrusion equipment by the conveyor, the motor adjusts the tip of the puncture needle to be directed downward, the hydraulic rod drives the puncture needle to penetrate the tire tread, the tire side or the inner liner;

[0016] The tip of the puncture needle is supported by the supporting force, so that the movable rod in the elastic mechanism moves inwardly to compress the spring, the sliding block moves inwardly to support the outer end arc of the pressing arm through the inclined surface, and the pressing arm rotates to press the sensing side of the tensile and compressive force sensor;

[0017] The change of the pressure on the sensing side can be reflected on the display screen of the control and display module in real time, when the puncture needle suddenly penetrates the tire tread, the tire side or the inner liner, the puncture needle quickly penetrates the tire tread due to the elastic force of the spring in the elastic mechanism, so that the movable rod quickly separates from the sliding block, and thus the pressure of the pressing arm on the tensile and compressive force sensor disappears instantaneously, and the reading of the control and display module drops to zero instantaneously, which indicates that the penetration has been completed.

[0018] The control motor drives the rotating drum to rotate at a uniform speed, and the sliding device slides along the track, and the eight puncture needles are arranged to be rotated along the extension direction of the tire tread, the tire side or the inner liner to detect and simulate the bearing capacity of each part of the tire tread, the tire side or the inner liner in each direction, as shown in the drawings, after the puncture needle penetrates the surface of the tested object, the penetration angle of the puncture needle changes in real time with the rotation of the rotating drum, so as to simulate the penetration of the tested object from the puncture needle in each direction during the rotation of the wheel, and verify the puncture-proof effect of the tested object, if the puncture needle penetrates the surface of the tested object, the effect is the same as the above, and the reading of the control and display module will drop sharply, which represents the penetration, so as to check the puncture-proof performance of the tested object under each penetration pressure and penetration angle, and each part of the tested object is detected as the puncture needle continuously rolls forward.

[0019] The application has the following beneficial effects:

[0020] 1. This invention achieves rapid pressure sensing by setting up an elastic mechanism, a puncture needle, a slider, and a pressure arm. After the puncture needle penetrates, the slider separates from the pressure arm. The tension and pressure sensor detects the step change in pressure and judges the penetration effect. No manual visual observation is required, which improves detection efficiency and speed and reduces the burden on staff.

[0021] 2. This invention enables horizontal sliding by setting up a control and display module, and a motor drives the rotating drum to rotate. The eight puncture needles on the outside of the rotating drum can puncture different parts of the object being inspected at once during the movement, so as to perform puncture-proof inspection on the entire surface of the object being inspected, thereby improving the comprehensiveness and accuracy of the inspection process.

[0022] 3. This invention simulates the puncture resistance of a wheel during rotation by changing the direction of the puncture force applied by the tip of the puncture needle to the test object in real time. This verifies the puncture resistance of the test object and examines its puncture resistance under various puncture pressures and puncture angles, thereby improving the comprehensiveness of the examination.

The outer end of the sliding block 10 is a vertical plane and is in contact with the inner end of the elastic mechanism 8. The inclined surface of the sliding block 10 pushes the contact end of the pressing arm 11 to tilt upward, and the other end of the pressing arm 11 tilts downward and presses the top of the tension and pressure sensor 12.

[0035] The top of the inner side of the intermediate slide 72 is provided with a cushion layer. The sliding block 10 is located above the cushion layer of the intermediate slide 72 and can slide up and down along the cushion layer. The cushion layer connects the outer layer plate surface 71 and the inner layer plate surface 73. The cushion layer first enhances the strength of the outer layer plate surface 71 and the inner layer plate surface 73, and provides a sliding support for the sliding block 10, plays a limiting role, and prevents the sliding block 10 from slipping off.

[0036] The elastic mechanism 8 includes a fixed cylinder 81, a spring 82, a fixed plate 83, a movable rod 84 and a clamping plate 85. The movable rod 84 is sleeved in the inner cavity of the fixed cylinder 81, the clamping plate 85 is arranged on the inner cavity wall of the fixed cylinder 81, the fixed plate 83 is arranged on the outer surface of the movable rod 84, the spring 82 is sleeved on the surface of the movable rod 84 and the two ends of the spring 82 are elastically supported between the fixed plate 83 and the clamping plate 85, the inner end of the elastic mechanism 8 is the inner end of the movable rod 84 and the sliding block 10, the outer end of the movable rod 84 is fixedly connected with the puncture needle 9, the fixed cylinder 81 is fixedly installed on the outer shell of the rotating drum 7, when the tip of the puncture needle 9 is supported, the spring 82 will first contract, and then the sliding block 10 is pressed, after the puncture needle 9 penetrates, the puncture needle 9 is further pushed by the elastic force of the spring 82, so that the movable rod 84 and the sliding block 10 are quickly separated.

[0037] The elastic mechanism 8 is equidistantly arranged on the outer shell of the rotating drum 7, the sliding block 10 and the pressing arm 11 in the inner cavity of the rotating drum 7 are equidistantly arranged in eight groups, and the inner end of each sliding block 10 is in contact with the inner end of one elastic mechanism 8, so that when the motor 6 controls the rotating drum 7 to rotate, the eight puncture needles 9 can rotate to puncture the detected object in turn, and the detection efficiency is improved.

[0038] The contact end of the pressing arm 11 and the sliding block 10 is provided with an arc surface, the length of the force arm of the contact end of the pressing arm 11 and the sliding block 10 is smaller than the length of the force arm of the contact end of the pressing arm 11 and the tension and pressure sensor 12, so that the internal space of the rotating drum 7 is saved, the diameter of the rotating drum 7 is relatively reduced, the pressing arm 11 is concentrated in the middle of the inner cavity of the rotating drum 7, and when the pressing arm 11 and the sliding block 10 are contacted and supported by a large force, the pressure applied to the top of the tension and pressure sensor 12 by the longer end of the pressing arm 11 is relatively small, so that the damage of the tension and pressure sensor 12 caused by excessive pressure is prevented.

[0039] The puncture needle 9 is provided below the conveyor 3, the conveyor 3 is provided with the detected tire tread, tire side or inner liner on the roller, and the conveyor 3 is used for automatic transfer and receiving of the detected object. In the detection process, the conveyor 3 is not working, and only works when the detected object is loaded or unloaded, so as to realize the transfer of the detected object.

[0040] The upper surface of the roller of the conveyor 3 is provided with a groove, the detected tire tread, tire side or inner liner covers the groove, and the groove is located directly below the puncture needle 9. The groove provides a space for the puncture needle 9 to penetrate, and the tip of the puncture needle 9 provides a recessed space for the detected object.

[0041] Wherein, the tire tread, sidewall or inner liner to be detected will be conveyed from the extruding device by the conveyor 3, the motor 6 adjusts the needle tip of the piercing needle 9 to point straight down, the hydraulic rod 4 starts to press down the piercing needle 9 to pierce the tire tread, sidewall or inner liner;

[0042] The tip of the piercing needle 9 is supported by the supporting force, so the movable rod 84 inside the elastic mechanism 8 moves the sliding block 10 inwards, and the spring 82 is compressed, the sliding block 10 slides inwards and its inclined surface supports the outer end arc surface of the pressing arm 11, forcing the pressing arm 11 to rotate, so that the inner end of the pressing arm 11 presses the sensing side of the tensile and compressive force sensor 12;

[0043] The change in pressure on the sensing side can be reflected in real time on the display screen of the control and display module 2, when the piercing needle 9 suddenly penetrates the tire tread, sidewall or inner liner, due to the elastic force of the spring 82 inside the elastic mechanism 8, the piercing needle 9 will quickly penetrate the tire tread, causing the movable rod 84 to quickly disengage from the sliding block 10, thus the pressure of the pressing arm 11 on the tensile and compressive force sensor 12 disappears instantaneously, the reading of the control and display module 2 drops to zero instantaneously, indicating that it has penetrated, the main purpose of the spring here is to speed up the disengagement speed between the sliding block 10 and the movable rod 84, thereby preventing the tensile and compressive force sensor 12 from sensing a change in pressure due to the retention of the piercing needle 9 in the penetration part;

[0044] The control motor 6 drives the rotating drum 7 to rotate at a uniform speed, and controls the sliding device 1 to slide along the track, the eight piercing needles 9 rotate in turn along the extension direction of the tire tread, sidewall or inner liner, sequentially detecting and simulating the bearing capacity of each part of the tire tread, sidewall or inner liner when pierced in each direction, such as Figure 7 As shown, after the piercing needle 9 pierces the surface of the tested object, the piercing angle of the piercing needle 9 will change in real time with the rotation of the rotating drum 7, thereby simulating the piercing of the tire tread, sidewall or inner liner from each angle of the sharp object during rotation, verifying the anti-piercing effect of the tested object, if the piercing needle 9 penetrates the surface of the tested object, the effect is the same as described above, the reading of the control and display module 2 will drop sharply, representing penetration, thereby checking how the anti-piercing performance of the tested object is under each penetration pressure and penetration angle, and as the piercing needle 9 continues to roll forward, each part of the tested object will be detected.
