Description

Technical Field

[0001] The present application relates to the field of tire production equipment, and in particular to a tire tread winding processing production line. Background Art

[0002] The radial tire tread winding process is mainly completed by the corresponding processing production line. In the related art, the production line used for tire tread winding process is composed of a cold material extruder, a press, a drum cooler, a conveying device and a winding main machine.

[0003] When the production line is in operation, the rubber strip used to process the tire tread is first heated by a cold material extruder and extruded to form a strip-shaped tread, then enters a forming machine for further pressing and molding, and then is initially cooled by a drum cooler, and then is pulled and transported to the winding main machine by a conveying device, and finally the winding main machine is equipped to wrap it around the tire embryo, thereby completing the winding process of the tire tread.

[0004] In order to facilitate the continuity of the subsequent cold material extruder feeding, the rubber material belt is usually folded and stacked on one side of the cold material extruder. When feeding the cold material extruder, the operator needs to pull one end of the rubber raw material and put it into the feeding funnel of the cooling extruder; the rubber material belt entering the feeding funnel is pulled by the extrusion screw rotating inside the cold material extruder, driving the remaining part of the rubber material belt to gradually enter the cold material extruder.

[0005] Regarding the above-mentioned related technologies, since the feed hopper of the cold material extruder is relatively high from the ground, the operator usually needs to use a ladder to pull the rubber material belt into the feed hopper, which is inconvenient and inefficient. At the same time, when the operator manually pulls and puts the rubber material belt into the feed hopper, if the operation is improper, it is very easy to contact with the moving parts inside the cooling extruder, and the overall operation is also dangerous. Therefore, there is room for improvement. Summary of the invention

[0006] In order to facilitate the feeding operation of a cooling extruder in a tire tread winding processing production line, the present application provides a tire tread winding processing production line.

[0007] The present application provides a tire tread winding production line, which adopts the following technical solution:

[0008] A tire tread winding processing production line, comprising a cold material extruder, a forming machine, a drum cooler, a conveying device and a winding main machine; the cold material extruder comprises a feeding hopper; the cold material extruder is also provided with an automatic feeding mechanism, the feeding mechanism comprises a material storage component, a grabbing component and an auxiliary conveying component;

[0009] The material storage assembly includes two material storage parts for storing rubber strips, and the two material storage parts are respectively located on opposite sides of the cold material extruder;

[0010] The grabbing assembly is arranged close to the material storage assembly and the feeding funnel; the grabbing assembly is used to grab the end of the rubber material belt located on the material storage part and move it to the feeding funnel;

[0011] The auxiliary conveying component is arranged close to the feeding funnel, and the auxiliary conveying component is used for assisting in conveying the rubber material belt into the feeding funnel.

[0012] By adopting the above technical solution, when feeding the cold material extruder, the end of the rubber material belt on a material storage part is grabbed by the grabbing component and moved to the top of the cold material extruder feeding funnel, and the rubber material is auxiliary conveyed to the feeding funnel by the auxiliary conveying component to complete the automatic feeding of the cooling extruder. Through the setting of two material storage parts, when the rubber material belt on one material storage part is in the feeding state, the rubber material belt on the other material storage part is used as a backup. When the rubber material belt in the feeding state is exhausted, the automatic feeding mechanism can quickly switch the rubber material belt on the other material storage part as a new feeding source through the grabbing component to improve the continuity of the cold material extruder feeding, which is conducive to maintaining the production efficiency of the cold material extruder.

[0013] Preferably, the grasping assembly includes a manipulator and a grasping portion, wherein the grasping portion is located at a driving end of the manipulator, and the grasping portion includes a grasping support plate, and a plurality of grasping suction cups are installed on the grasping support plate.

[0014] By adopting the above technical solution, when the rubber material belt is transferred from the material storage part to the feeding funnel through the grabbing assembly, the robot first drives the grabbing part to move to the rubber material belt to be moved, and then the surface of the rubber material belt is sucked and fixed by a number of grabbing suction cups of the grabbing part to complete the firm grip of the rubber material belt by the grabbing part, and then the robot drives the grabbing part to drive the gripped rubber material belt to move above the feeding funnel.

[0015] Preferably, the auxiliary conveying assembly includes two supporting frames, which are respectively supported on opposite sides of the feed funnel; a conveying part is provided on the top of the supporting frames, and the two conveying parts are both located above the feed funnel; the conveying part includes a first support, which is horizontally rotatably connected to a conveying roller, and the first support is also provided with a first rotary driving member for driving the conveying roller to rotate; a conveying gap is left between the conveying rollers of the two conveying parts for the rubber belt to pass through.

[0016] By adopting the above technical solution, the subsequent robot cooperates with the grasping part to move the rubber material belt from the material storage part to the top of the feeding mechanism, and after the drooping part of the rubber material belt is extended into the conveying gap between the two conveying rollers, the corresponding conveying rollers are driven to rotate by the first rotary driving parts on the two first supports, and the relative rotation of the two conveying rollers is utilized to realize the rapid guidance of the rubber material belt into the conveying feed funnel; at the same time, the grasping part does not need to enter the feed funnel, thereby reducing the collision and interference between the grasping part and the feed funnel during the movement.

[0017] Preferably, the support frame is provided with a first sliding drive member corresponding to the conveying portion, and the first sliding drive member is drivingly connected to the conveying portion for driving the conveying portion to slide in a horizontal direction toward or away from the support frame.

[0018] By adopting the above technical solution, before the grabbing assembly transfers the rubber material belt from the material storage part to the feeding funnel, the first sliding drive member on the supporting frame drives the corresponding conveying part to slide in the direction close to the conveying frame, so that the two conveying parts are separated from each other and the conveying gap between the two conveying rollers is increased; after the grabbing assembly grabs and moves the rubber material belt to the feeding funnel and places the drooping part of the end of the rubber material belt between the two conveying rollers, the first sliding drive member is used to drive the conveying part to slide in the direction away from the corresponding conveying frame until the two conveying rollers are respectively in contact with the opposite sides of the rubber material belt, so that the rubber material belt can be subsequently guided into the feeding funnel through relative rotation of the two conveying rollers.

[0019] Preferably, a support portion is also provided on the top of the support frame, and the support portion is located on the conveying path of the rubber belt. The support portion includes a second support, and the second support is rotatably connected to a support roller, and the support roller is used for overlapping the rubber belt; the support portion and the conveying portion are respectively located on opposite sides of the support frame, and the support roller and the conveying roller are arranged at the same height.

[0020] By adopting the above technical solution, the support roller and the conveying roller are used to support the rubber belt away from the support frame and the feeding funnel, thereby reducing the friction between the rubber belt and the support frame feeding funnel during the subsequent transmission process, which affects the smoothness of the rubber belt transmission.

[0021] Preferably, the second support is further provided with a second rotary driving member for driving the supporting roller to rotate.

[0022] By adopting the above technical solution, the support roller is driven to rotate by the second rotary drive member, and the rotating support roller is used to assist in conveying the rubber strip, which is conducive to more stable and smooth transportation of the rubber strip into the cold material extruder.

[0023] Preferably, a flushing portion is also provided on the support frame, and the flushing portion is located between the conveying portion and the support portion; the flushing portion includes a flushing bracket, a flushing seat is supported on the flushing bracket, and the flushing seat is provided with an upper air knife and a lower air knife, and the upper air knife and the lower air knife are respectively located above and below the conveying path of the rubber material belt, and the air outlets of the upper air knife and the lower air knife are both arranged toward the conveying path of the rubber material belt.

[0024] By adopting the above technical solution, during the transmission of the rubber strip, the upper air knife and the lower air knife on the flushing seat are used to continuously blow compressed air toward the rubber strip during the transmission process to remove impurities and pollutants adhering to the rubber strip, thereby reducing the situation where impurities and pollutants follow the rubber strip into the cold material extruder and affect the purity of the subsequent rubber strip.

[0025] Preferably, a second sliding drive member is further provided on the flushing bracket, and the second sliding drive member is drivingly connected to the flushing seat and is used to drive the flushing seat to slide in a horizontal direction toward or away from the rubber material belt conveying path.

[0026] By adopting the above technical solution, before the grabbing assembly transfers the rubber material strip from the material storage portion to the feed hopper, the second sliding drive component drives the flushing seat to drive the upper air knife and the lower air knife to move in a direction away from the rubber material strip transmission path, so as to reduce the interference between the flushing portion and the rubber material strip during the subsequent grabbing assembly grabbing and moving the rubber material strip; after the subsequent grabbing assembly grabs the rubber material strip in place, the second sliding drive component drives the flushing seat to drive the upper air knife and the lower air knife to move in a direction close to the rubber material strip transmission path until both the upper air knife and the lower air knife are facing the rubber material strip, so as to facilitate the upper air knife and the lower air knife to blow away impurities and pollutants adhering to the opposite sides of the rubber material strip.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When feeding the cold material extruder, the rubber material belt located on the material storage part is grabbed by the grabbing assembly and moved to the top of the feeding funnel of the cold material extruder and placed in the conveying gap formed by two conveying rollers. The rubber material belt is quickly introduced into the cold material extruder through the relative rotation of the two conveying rollers to realize automatic feeding of the cold material extruder, which is beneficial to improve the efficiency and convenience of the feeding operation of the cold material extruder.

[0029] 2. By arranging a first sliding drive member on the support frame, before the grabbing assembly grabs the rubber material belt at the material storage part to the top of the feed funnel, the first sliding drive members on the two support frames cooperate to drive the two conveying parts to move away from each other, so as to increase the gap between the conveying rollers of the two conveying parts, thereby facilitating the grabbing assembly to put the rubber material belt into the gap between the two conveying rollers; after the grabbing assembly subsequently puts the end of the rubber material belt between the conveying rollers of the two conveying parts, the two first sliding drive members cooperate to drive the two conveying parts to move closer to each other and abut against the rubber material belt, so as to facilitate the subsequent relative rotation of the two conveying rollers to guide the rubber material belt into the cold material extruder.

[0030] 3. Through the setting of the flushing section, during the traction process of the rubber belt, compressed air can be blown toward the rubber belt through the upper and lower air knives of the flushing section to remove impurities and pollutants adhering to the rubber belt, which is helpful to reduce the impurities and pollutants entering the cold material extruder along with the rubber belt.

The auxiliary conveying component 63 is arranged near the feed funnel 11, and is used to assist in conveying the rubber strip into the feed funnel 11.

[0042] By setting up two material storage sections 61, during the operation of the cold material extruder 1, when the rubber material belt in one of the material storage sections supplies the cold material extruder 1, the rubber material belt on the other material storage section 61 can be used as a backup. However, after the rubber material belt on the storage section is exhausted, the grabbing assembly 62 can grab the rubber material belt on the other material storage section 61 to the feed funnel 11 of the cold material extruder 1 to continue supplying the cold material extruder 1.

[0043] The material storage part 61 includes a material storage platform 611, and a plurality of universal wheels 612 are installed at the bottom of the material storage platform 611. The material storage platform 611 can be flexibly moved through the bottom universal wheels 612, so as to facilitate the subsequent transportation and movement of the rubber material belt through the material storage platform 611. A handrail is also installed on one side of the material storage platform 611.

[0044] Reference Figure 2 and Figure 3 The grabbing assembly 62 includes a manipulator 621 and a grabbing part, and the grabbing part is installed at the driving end of the manipulator 621. In this embodiment, the manipulator 621 is a two-axis truss manipulator 621, and the grabbing part includes a grabbing support plate 622, and the grabbing support plate 622 is connected to the driving end of the manipulator 621. The grabbing support plate 622 is installed with a plurality of grabbing suction cups 623, and the grabbing suction cups 623 are used to hold the rubber material strip. When the grabbing assembly 62 is used to grab and move the rubber material strip, the grabbing manipulator 621 drives the grabbing part to move above the rubber material strip corresponding to the material storage part 61, and then the manipulator 621 drives the grabbing part to move downward, and after the end of the target rubber material strip is held by the plurality of grabbing suction cups 623 on the grabbing part, the manipulator 621 drives the grabbing part to drive the grabbed rubber material strip to move.

[0045] Reference Figure 2 and Figure 4 The auxiliary conveying assembly 63 includes two support frames 630, and the two support frames 630 are respectively supported on opposite sides of the feed hopper 11; the two storage parts are located on the side of the two support frames 630 that are away from each other, and the support frames 630 are arranged higher than the storage parts.

Specifically, the first rotary drive member is a reduction motor.

[0046] The two first conveying parts 631 are both located above the feeding hopper 11 , and a conveying gap for the rubber strip to pass through is reserved between the conveying rollers 6312 on the two conveying parts 631 .

[0047] Through the above settings, the subsequent manipulator 621 cooperates with the grabbing part to grab the rubber material belt to the feed funnel 11 and grabs it above the feed funnel 11, and puts the drooping part of the end of the rubber material into the conveying gap between the conveying rollers 6312 of the two conveying parts 631. The first rotary driving parts on the two first supports 6311 cooperate to drive the two conveying rollers 6312 to rotate relative to each other, so that the rubber material belt is conveyed downward into the feed funnel 11. On the one hand, it is convenient to quickly guide and convey the rubber material belt into the feed funnel 11; at the same time, the grabbing part does not need to enter the feed funnel 11, which effectively reduces the situation where the grabbing part is easy to collide with the feed funnel 11 when moving in the limited space in the feed funnel 11.

[0048] The support frame 630 is provided with a first sliding driving member 632 corresponding to the conveying portion 631, and the first sliding driving member 632 is drivingly connected to the corresponding conveying portion 631, and is used to drive the corresponding conveying portion 631 to slide in a horizontal direction toward or away from the support frame 630. Specifically, the first sliding driving member 632 includes two first sliding cylinders, and the piston rods of the two first sliding cylinders are respectively connected to opposite ends of the first slide seat.

[0049] Through the setting of the first sliding drive member 632, before the grabbing assembly 62 grabs and moves the upper material belt of the material storage section 61 to the top of the feeding funnel 11, the first sliding drive member 632 on the supporting frame 630 drives the corresponding conveying section 631 to move in the direction close to the supporting frame 630, so that the conveying rollers 6312 on the two conveying sections 631 are separated from each other, thereby increasing the conveying gap between the two conveying rollers 6312, so as to facilitate the subsequent grabbing assembly 62 to place the rubber material belt into the conveying gap between the two conveying rollers 6312; after the grabbing assembly 62 places the drooping part of the end of the rubber material belt into the conveying gap between the two conveying rollers 6312, the first sliding drive member 632 drives the corresponding conveying section 631 to move in the direction away from the supporting frame until the conveying rollers 6312 on the two conveying sections 631 respectively abut against the opposite sides of the rubber material belt, so as to facilitate the subsequent relative rotation of the two conveying rollers 6312 to convey the rubber material belt downward into the feeding funnel 11.

[0050] Reference Figure 4 and Figure 5The support frame 630 is also provided with a support portion 633 on the top, and the support portion 633 and the conveying portion 631 are respectively located on opposite sides of the support frame 630; the support portion 633 includes a second support 6331, and the second support 6331 is rotatably connected to a support roller 6332, and the second support 6331 is also provided with a second rotary drive member 6333 for driving the support roller 6332 to rotate.

The axis directions of the support roller 6332 and the conveying roller 6312 are parallel, and the support roller 6332 and the conveying roller 6312 are arranged at the same height.

[0051] The support roller 6332 and the conveying roller 6312 cooperate to support the rubber strip away from the support frame 630, thereby reducing the interference and friction between the rubber strip and the support frame 630 during the conveying process, which is beneficial to the smooth conveying of the rubber strip. At the same time, the second rotary drive member 6333 is used to drive the support roller 6332 to rotate, and the rotating conveying roller 6312 is used to assist in the conveying, which is beneficial to further improve the stability of the rubber strip during the conveying process.

[0052] Reference Figure 5 and Figure 6 , a flushing portion 634 is also provided on the top of the support frame 630, and the flushing portion 634 is located between the conveying portion 631 and the support portion 633. The flushing portion 634 includes a flushing bracket 6341, and a flushing seat 6342 is supported on the flushing bracket 6341, and the flushing seat 6342 is horizontally installed with an upper air knife 6343 and a lower air knife 6344 from top to bottom.

[0053] By setting up the flushing portion 634, before the grabbing assembly 62 grabs the rubber material belt on the material storage portion 61 to the top of the feeding funnel, the second sliding drive member 6345 drives the flushing seat 6342 to drive the upper air knife 6343 and the lower air knife 6344 to move away from the rubber material belt conveying path, so that the upper air knife 6343 and the lower air knife 6344 are away from the rubber material belt conveying path, thereby reducing the interference between the rubber material belt and the flushing portion 634 during the subsequent process of the rubber material belt grabbed by the grabbing assembly 62 and moving it to the feeding funnel 11. After the grabbing assembly 62 grabs the rubber belt and makes the rubber belt overlap the conveying roller 6312 and the supporting roller 6332 on the top of the supporting frame 630, the second sliding drive member 6345 drives the flushing seat 6342 to drive the upper air knife 6343 and the lower air knife 6344 to move in the direction close to the rubber belt until the upper air knife 6343 and the lower air knife 6344 are located above and below the conveying path of the rubber belt; when the rubber belt subsequently enters the feed funnel 11 step by step through the cooperation of the two conveying rollers 6312, the upper air knife 6343 and the lower air knife 6344 blow compressed air to the opposite sides of the rubber belt to remove impurities and pollutants adhering to the surface of the rubber belt, thereby reducing the situation where impurities and pollutants enter the cold material extruder 1 with the rubber belt.
