Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a guide device. Background Art

[0002] In the production process of engineering tires, the production of steel cords in the belt layer plays a vital role. In the production process of steel cords in the belt layer, the production process of the small-angle steel cord cutting machine will play a decisive role in the quality of the belt layer. In view of the requirements of the maximum calendering cord thickness of 10mm and the maximum steel wire diameter of 6mm for engineering tire belt layer steel cords, some of the existing structural forms will have great risks in strength.

[0003] The main function of the guide device of the small-angle steel cord cutting machine for engineering tires is to peel off the padding of the calendered cord and transfer the peeled cord to the conveyor frame after rough deviation correction. Under the action of the pull-out roller, the cord is pulled and transferred to the cloth delivery device through the mechanical centering device. Among them, due to the production of small-angle steel cord, the guide device has several functions that need to be realized. First, it is to realize the rotation and positioning of the cutting angle; second, it is to realize the inspection and alarm of impurities on the surfaces of both sides of the cord; third, it is to realize the splicing of the tail of the used material roll with the head of the new material roll. In the existing guide device of the small-angle steel cord cutting machine, the trolley is a separate part, connected to the trolley chassis through two linear guides and two wheels, and the rough deviation correction of the trolley is realized by the trolley moving back and forth on the trolley chassis through the linear guides and wheels. The distance between the trolley part and the conveyor frame is relatively close. When it is subjected to a large load, the trolley will be pulled and subjected to force toward the conveyor frame. The connection between the trolley and the chassis is weak. When the trolley is correcting its deviation, if it is subjected to a large lateral force, the effect of the rough correction will be affected.

[0004] Therefore, there is a problem in the prior art that the guide device of the steel cord cutting machine has poor performance. Utility Model Content

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0025] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0026] In order to solve the problem of poor performance of the guide-out device of the steel cord cutting machine in the prior art, the present application provides a guide-out device.

[0027] like Figure 1 and Figure 2 As shown, the deflection device in the present application includes a base frame 10, a deflection opening assembly 20, a conveying frame body 30, and a deviation correction drive assembly 40. The deflection opening assembly 20 is arranged on the base frame 10 and moves with the base frame 10; the conveying frame body 30 and the deflection opening assembly 20 are arranged at intervals; the deviation correction drive assembly 40 is connected to the base frame 10 in a driving manner, so that the base frame 10 drives the deflection opening assembly 20 to move in a direction close to or away from the conveying frame body 30.

[0028] When the deflection device in the present application is used, since the deflection vehicle assembly 20 is arranged on the chassis 10 and moves with the chassis 10, the deflection vehicle assembly 20 and the chassis 10 can withstand stronger lateral loads when the deflection device moves, and the risk of the guide vehicle assembly coming out can be avoided. At the same time, since the deviation correction drive assembly 40 is connected to the chassis 10 in driving in the present application, compared with the deflection trolley of the traditional deflection device, when deflecting thicker materials such as engineering tires that need to withstand greater loads, the rough deviation correction effect is better and more stable. Therefore, the deflection device in the present application effectively solves the problem of poor performance of the deflection device of the wire cord cutting machine in the prior art.

[0029] It should be noted that in the present application, the base frame 10 drives the guide carriage assembly 20 to move in a direction close to or away from the conveying frame body 30 as a deviation-correcting movement.

[0030] Specifically, the deflection device also includes a plurality of running wheels 50, and the plurality of running wheels 50 are arranged on the side of the chassis 10 away from the deflection vehicle assembly 20. Furthermore, it should be noted that in the present application, a track plate that cooperates with the running wheels 50 can be provided to ensure that the running wheels 50 can move along the track plate, thereby enabling the chassis 10 to drive the deflection vehicle assembly to move along a preset direction. Furthermore, in the present application, the deflection device can also be provided with an angle rotation motor, and the angle rotation motor drives the chassis 10 to drive the deflection vehicle assembly 20 to perform rotational movement on the track plate. Furthermore, the direction of the deviation correction movement is tangent to the direction of the rotational movement, and at the same time, the specific distance of the deviation correction movement is much smaller than the distance of the rotational movement, so the chassis 10 can perform rotational movement and deviation correction movement on the same track plate.

[0031] Moreover, in the present application, a joint support plate assembly 80 is also provided on one side of the conveying frame 30 close to the guide opening assembly 20. The joint support plate assembly 80 is preferably made of aluminum and is used to realize manual jointing of the tail of the used material roll and the head of the new material roll.

[0032] Optionally, the guide car assembly 20 is welded on the base frame 10. Of course, the guide car assembly 20 can also be fixedly arranged on the base frame 10 in other ways, as long as the guide car assembly 20 can move with the base frame 10.

[0033] Optionally, the guide wheel assembly 20 and the conveying frame body 30 are spaced apart along the length direction of the base frame 10. This arrangement can facilitate operators to enter between the conveying frame body 30 and the guide wheel assembly 20 to handle abnormal production of engineering tires.

[0034] Specifically, the deflection correction drive assembly 40 includes a drive unit 41, a drive screw 42 and a drive nut 43. The drive unit 41 is connected to the drive screw 42 and drives the drive screw 42 to rotate; the drive nut 43 is sleeved on the drive screw 42 and can move along the length direction of the drive screw 42, and the base frame 10 is connected to the drive nut 43 and moves with the drive nut 43. In a specific embodiment of the present application, in the horizontal direction, the drive unit 41 is arranged on the side of the conveying frame 30 away from the guide opening assembly 20. In other words, in the horizontal direction, the distance from the drive unit 41 to the conveying frame 30 is less than the distance from the conveying unit to the guide opening assembly 20. Moreover, in the present application, when the deflection correction drive assembly 40 drives the base frame 10 and the guide opening assembly 20, the position of the drive unit 41 generally does not change.

[0035] Preferably, the length direction of the driving screw 42 is the same as the length direction of the conveying frame body 30. By setting it in this way, it can be ensured that the deviation correction driving assembly 40 can drive the base frame 10 more easily.

[0036] Optionally, the deviation-correcting drive assembly 40 further includes a coupling 44, and the driving portion 41 is connected to the driving screw 42 via the coupling 44. Preferably, the coupling 44 is a drum-type gear coupling 44.

[0037] Optionally, the deviation correction drive assembly 40 further includes a fixed seat 45, which is arranged on a side of the driving portion 41 close to the driving screw 42, and the conveying frame 30 is arranged on the fixed seat 45. Preferably, the fixed seat 45 in the present application can be sleeved on the driving screw 42 through an oil-free bearing 90.

[0038] Optionally, the deviation correction drive assembly 40 also includes at least one connecting member 46, one end of the connecting member 46 is connected to the drive nut 43, and the other end of the connecting member 46 is connected to the chassis 10. In a specific embodiment of the present application, the connecting member 46 is a bolt, and the chassis 10 is provided with a connecting protrusion corresponding to the drive nut 43, and the drive nut 43 and the connecting protrusion are respectively provided with threaded holes corresponding to the bolt. In this way, the drive nut 43 can be connected to the chassis 10 by the bolt. Moreover, by such a setting, it can also be ensured that the drive nut 43 will not rotate with the drive screw 42 during the rotation of the drive screw 42, but will move relative to the drive screw 42 along the length direction of the drive screw 42, thereby driving the chassis 10 and the guide car assembly 20 to move, thereby realizing the deviation correction adjustment of the deviation correction car assembly. Moreover, it should be noted that the threaded hole in which the drive nut 43 cooperates with the bolt is a threaded hole that penetrates the circumferential side wall of the nut. The internal thread of the drive nut 43 is used to cooperate with the drive screw 42.

[0039] Optionally, the deviation correction drive assembly 40 further includes a pressure injection oil cup 47, which is sleeved on the drive screw 42 and connected to a side of the drive nut 43 close to the drive portion 41. Preferably, the pressure injection oil cup 47 is a straight-through pressure injection oil cup 47.

[0040] Specifically, the deflection device further includes at least three detection switches, a first detection plate 60, and a second detection plate 70 arranged at intervals along the length direction of the base frame 10. The detection switches are arranged on the conveying frame body 30; the first detection plate 60 and the second detection plate 70 are respectively arranged on the driving nut 43 and move with the driving nut 43, the length direction of the second detection plate 70 is parallel to the connection direction of the three detection switches, and the length direction of the first detection plate 60 is perpendicular to the length direction of the second detection plate 70.

[0041] Preferably, the detection switch is a proximity switch.

[0042] In a specific embodiment of the present application, the lower end of the conveying frame body 30 has a mounting plate extending toward the guide vehicle assembly, and three detection switches are arranged on the mounting plate at intervals, and the specific setting positions of the three detection switches are related to the deviation correction movement of the base frame 10 and the guide vehicle assembly. When the first detection plate 60 is aligned with the detection switch located in the middle of the three detection switches, it indicates that the guide vehicle assembly is in the center position of the deviation correction movement, and when the first detection plate 60 is not aligned with the detection switch located in the middle of the three detection switches, the driving direction of the deviation correction drive assembly 40 to the base frame 10 and the guide vehicle assembly 20 can be determined by the specific detection results of the second detection switch and the three detection switches, so that the base frame 10 and the guide vehicle assembly 20 move in the direction in which the first detection plate 60 is aligned with the detection switch located in the middle of the three detection switches. At the same time, through the cooperation of the two detection switches located at the two ends of the three detection switches with the second detection plate 70, it is also possible to judge whether the guide vehicle assembly 20 has moved to the extreme position. Therefore, in the present application, the deviation correction drive assembly 40 can determine the driving direction of the base frame 10 and the guide trolley according to the detection results of the three detection switches and the first detection plate 60 and the second detection plate 70.
