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

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0030] 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 direction; 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 directional words are not used to limit the present invention.

[0031] In order to solve the problem of poor quality of small-angle steel cord belt joints of engineering tires and jumbo tires in the prior art, the present invention provides a production method and device for a cord belt cutting machine.

[0032] like Figure 1 The production method of a cord belt layer cutting machine shown in the figure includes: the joint conveyor belt conveys the cord in a forward direction to a predetermined position; the positioning baffle 21 of the joint device 20 descends to the movement path of the cord, the joint conveyor belt conveys in the reverse direction and makes the tail 152 of the previous cord abut against the front side of the positioning baffle 21 for positioning; the lifting component of the joint conveyor belt rises and drives the previous cord to rise, and the previous cord leaves the joint conveyor belt; the joint conveyor belt conveys in a forward direction and conveys the next cord to the positioning baffle 21, so that the head 151 of the next cord abuts against the rear side of the positioning baffle 21 for positioning; the lifting component descends and drives the previous cord to descend, and the previous cord is supported on the joint conveyor belt; the pressure roller 22 of the joint device 20 acts to connect and sew the tail 152 of the previous cord and the head 151 of the next cord.

[0033] The production method of the embodiment described above utilizes the positioning baffle 21 and the jacking assembly, wherein the positioning baffle 21 can position the position of the cord, and ensure that the head and tail of the cord are at the position of butt joint stitching, and the jacking assembly controls the contact and separation relationship between the cord and the joint conveying belt, so that the joint conveying belt does not affect the cord that has been positioned when conveying another cord, so that the two cords are positioned by cooperating with the positioning baffle 21 respectively, the head 151 and the tail 152 of the two cords are butt jointed, and the butt joint stitching process is successfully completed. Specifically, when jointing, the joint conveying belt first conveys a cord to make the cord abut against the positioning baffle 21 to realize positioning, and then the jacking assembly lifts the cord, so that the cord no longer contacts the joint conveying belt, so that the joint conveying belt can convey the next cord without affecting the position of the previous cord. After the next cord is conveyed and positioned, the previous cord can be placed on the joint conveying belt again, and the joint device 20 can butt joint the two cords. The above setting mode can directly and actively convey the cord bevel from the joint conveying belt to the joint position when jointing the cord, so as to realize the automation of the whole joint stitching process, solve the problems of unreliable, low efficiency, high labor intensity and the like of the current manual jointing of the small angle steel cord belt of the engineering tire and the giant tire, and realize the full-automatic solution.

[0034] As shown in Figures 2 to 5 The production device of the cord belt joint integrated machine adopted by the production method of the cord belt joint integrated machine of the embodiment includes a joint conveying device 10 and a joint device 20, wherein the joint conveying device 10 includes a joint conveying belt and a jacking assembly, the jacking assembly can be lifted to a height higher than the joint conveying belt, so as to lift the cord and separate the cord from the joint conveying belt, and the joint device 20 includes a compression roller 22, which can realize butt joint stitching of the head and tail.

[0035] It should be noted that the production method and device of the embodiment are mainly used for processing the cord belt of the engineering tire and the giant tire, and of course, the production method and device of the embodiment can also be used on other types of tires. The front and back of the embodiment are in the conveying direction of the cord, the back side is close to the starting end of the conveying, and the front side is close to the end of the conveying, so that the front side and the back side are opposite sides.

[0036] In the embodiment, the production method of the belt and belt joint cutting all-in-one machine further comprises: before or after the positioning baffle 21 is lowered, the joint device 20 is rotated under the driving of the rotating driving member 25, so that the joint device 20 is at a predetermined angle with the cutting line of the cord fabric. In this way, the angle of the joint device 20 is adapted to the required cutting angle of the cord fabric, so as to ensure the accuracy of the joint. The time of the overall rotation of the joint device 20 can be adjusted as required, which can be before the baffle is lowered or after the baffle is lowered and before the cord fabric is positioned. The latter is adopted in the embodiment, that is, the joint device 20 is rotated after the positioning baffle 21 is lowered, and then the cord fabric is conveyed and positioned.

[0037] Based on the rotatable arrangement of the joint device 20, the predetermined position of the cord fabric conveyed by the joint conveying belt in the forward direction to the predetermined position is the position of the cord fabric passing through the rotation axis of the joint device 20, that is, the tail end 152 of the cord fabric passing through the position corresponding to the rotation axis of the joint device 20 on the joint conveying belt.

[0038] In the embodiment, the production method of the belt and belt joint cutting all-in-one machine further comprises: when the pressure roller 22 is stitching the jointed cord fabric, the mounting frame 26 is driven by the pressure roller driving member 27 to move along the cross beam 24, and the pressure roller 22 is driven by the mounting frame 26 to move along the cross beam 24. Since the extension direction of the cross beam 24 is aligned with the direction of the bevel of the cord fabric after the rotation of the joint device 20, the movement of the pressure roller 22 along the cross beam 24 can move along the required stitching line, so as to realize the butt joint stitching of the cord fabric.

[0039] In the embodiment, the production method of the belt and belt joint cutting all-in-one machine further comprises: before the joint conveying belt conveys the cord fabric, the guide opening device 30 and the cord feeding device 40 of the pre-processing device are rotated relative to the cutting device 50, and a required cutting angle is formed so that the cut cord fabric meets the angle requirement of processing; the cord fabric is guided by the guide opening device 30, and the cord fabric is centrally conveyed to the cutting device 50 through the cord feeding device 40; the cord fabric is pulled in the direction of the cutting angle by the cord pulling device 70, so as to realize the cutting angle pulling; the cord fabric at the required cutting angle is cut by the cutting device 50; the cut cord fabric is taken by the cutting conveying device 60 through the lifting of the air cylinder and is conveyed to the feeding conveying device 80, and the feeding conveying device 80 conveys the cord fabric to the joint conveying belt.

[0040] In the embodiment, the production method of the belt and belt joint cutting integrated machine further includes: after the jointing and stitching of the jointing device 20, the jointing and stitching belt is sequentially sent through the manual joint conveying belt 90, the unloading conveying belt 100, the balancing roller device 110, the positive rubber sheet attaching device 120, the reverse rubber sheet attaching device 130 and the winding device 140 to perform manual processing, unloading, sheet attaching and winding operations. It should be noted that not all of the jointing and stitching devices need to function, for example, the manual joint conveying belt 90 is mainly used to complete manual stitching of the belt at an angle of 10-15°, when the angle of the belt is not 10-15°, the manual joint conveying belt 90 can be omitted, and the belt can be directly conveyed through the manual joint conveying belt 90, and similarly, the positive rubber sheet attaching device 120 and the reverse rubber sheet attaching device 130 are respectively used for positive rubber sheet attaching and reverse rubber sheet attaching, and thus when the positive rubber sheet and the reverse rubber sheet are not needed, the positive rubber sheet attaching device 120 and the reverse rubber sheet attaching device 130 can be omitted.

[0041] As shown in Figures 2 to 5 The embodiment also provides a belt and belt joint cutting integrated machine production device, which is matched with the production method described above, and the two are matched to realize the processing of the belt and belt. The belt and belt joint cutting integrated machine production device includes a front processing device for guiding and cutting the belt, a joint conveying device 10, a joint device 20 and a rear processing device for rubber sheet attaching and winding. The joint conveying device 10 is connected to the front processing device and conveys the belt, the joint conveying device 10 includes a joint conveying belt and a jacking assembly, the jacking assembly is located on the side of the joint conveying belt and can be raised above the upper surface of the joint conveying belt to jack up the belt on the joint conveying belt; the joint device 20 is located above the joint conveying device 10, the joint device 20 includes a positioning baffle 21 and a pressing roller 22, the positioning baffle 21 is arranged to be liftable and can abut against the belt to position the belt, and the pressing roller 22 is arranged to be transversely movable and can connect two belts; the rear processing device is connected to the joint conveying device 10. In this way, through the cooperation of the joint conveying device 10 and the joint device 20, the sequential positioning and stitching of two belts are realized, thereby realizing efficient, rapid and automatic jointing of the small-angle steel cord belt of the engineering tire and the giant tire.

[0042] Considering that the embodiment is for the engineering tire and the giant tire, the pressing roller 22 for jointing can adopt a giant tire special pressing roller 22, thereby increasing the jointing closing force.

[0043] As shown in Figure 4As shown, in the embodiment, the joint conveying belts are multiple, and the joint conveying belts are arranged at intervals, and the length direction of the joint conveying belts is parallel to the conveying direction of the cord fabric, so that the direction of the interval arrangement between the joint conveying belts is perpendicular to the length direction. Correspondingly, the jacking assemblies are multiple, and the jacking assemblies are arranged in the intervals between the joint conveying belts. The jacking assembly can adopt the structure form of a cylinder plus a jacking block. The cylinder rod is arranged to move up and down, and the jacking block is located at the top end of the cylinder rod, so that the jacking block can move up and down under the drive of the cylinder, and is lifted to a position protruding above the upper surface of the joint conveying belt or is lowered to a position below the upper surface of the joint conveying belt, to realize the lifting and releasing of the cord fabric. Of course, the specific arrangement mode of the joint conveying belt and the jacking assembly and the specific structure form of the jacking assembly are not limited to the arrangement mode described above in the embodiment, and can be adjusted as needed, for example, the joint conveying belt is arranged as a whole conveying belt with a relatively wide width, and the jacking assembly is arranged at the side surface and can adopt a structure of a clamping jaw, so that the cord fabric can be clamped and lifted.

[0044] Optionally, the starting end of the joint conveying belt can be provided with a speed reducer, a positioning detection component, etc. as needed.

[0045] As shown in the figure, Figure 3 In the embodiment, the joint device 20 further comprises a rack 23 and a cross beam 24. The rack 23 is arranged above the joint conveying belt, and the rack 23 is rotatably arranged relative to the joint conveying device 10, and the rotation center of the rack 23 is located on the stitching line of the cord joint. The cross beam 24 is located below the part of the rack 23 which is arranged above the joint conveying belt. The length direction of the cross beam 24 forms an angle with the length direction of the joint conveying belt. The positioning baffle 21 is connected to the cross beam 24 in a manner that can be lifted and lowered. The compression roller 22 is movably arranged below the cross beam 24 along the length direction of the cross beam 24.

[0046] Specifically, the rack 23 of the embodiment adopts a door-shaped structure, which includes two longitudinal racks and a transverse rack. The two longitudinal racks are respectively located on the two sides of the joint conveying belt, and the transverse rack is located above the joint conveying belt and connected to the top ends of the two longitudinal racks at two ends, so that the length direction of the transverse rack forms an included angle greater than 0 degrees with the joint conveying belt. When the rack 23 rotates, the position of the transverse rack also naturally rotates to change the positional relationship with the cord, thereby achieving adjustment of the stitching angle. An extended section is transversely extended at the bottom end of one of the longitudinal racks, and the extended section is rotatably connected to external ground platforms, bases and other components through a rotating shaft and the like, so that the entire rack 23 can rotate around the rotating shaft. A cross beam 24 is arranged below the transverse rack, and the cross beam 24 and the transverse rack can be connected together through a longitudinal connecting section, so that the cross beam 24 rotates together with the rack 23. A guide rail is arranged below the cross beam 24, and the pressing roller 22 and the positioning baffle 21 are arranged on the cross beam 24. The pressing roller 22 can move along the guide rail to achieve stitching of the entire stitching line, and the positioning baffle 21 is arranged on the cross beam 24 in a telescopic lifting manner, so that the positioning baffle 21 can be lowered for positioning or lifted to avoid obstacles.

[0047] In the embodiment, considering that the size of the cord is large and the cross beam 24 has a certain length, the positioning baffle 21 of the embodiment is provided with a plurality of positioning baffles 21, and the positioning baffles 21 are arranged along the length direction of the cross beam 24 and synchronously act. Therefore, all the positioning baffles 21 are lowered at the same time during positioning, thereby ensuring the positioning effect on each position of the cord bevel. Similarly, the pressing roller 22 is provided with two pressing rollers 22, and the two pressing rollers 22 are located at the two ends of the cross beam 24. Therefore, the two pressing rollers 22 can reciprocate along the length direction of the cross beam 24 towards or away from each other at the ends of the cross beam 24 to achieve stitching, and return to the ends of the cross beam 24 after stitching. Of course, the positioning baffle 21 can also be provided with only one positioning baffle 21, and the positioning baffle 21 itself has a certain length, so as to cover the positioning requirement of the cord bevel. Similarly, the pressing roller 22 can also be provided with only one pressing roller 22, and the pressing roller 22 passes through the entire length of the cross beam 24 to achieve stitching of the joint.

[0048] In the embodiment, the rotating axis of the rack 23 is longitudinally arranged and located on one side of the joint conveying belt. The rotating axis of the rack 23, that is, the rotating shaft at the extended section, is located outside the range of the joint conveying belt, so that the rotation of the rack 23 does not interfere with the joint conveying belt. The joint device 20 further includes a rotating driving member 25, which is drivingly connected to the rack 23. In the embodiment, the rotating driving member 25 is arranged at the longitudinal rack without the extended section, so that the rack 23 can be driven to rotate around the rotating shaft by driving the longitudinal rack on this side.

[0049] In the embodiment, the joint device 20 further comprises a mounting frame 26, a press roller driving element 27 and an anti-overlapping plate. The mounting frame 26 is mounted on the cross beam 24 and is movably arranged on the cross beam 24 through the guide rail at the bottom of the cross beam 24. The components that need to be moved, such as the press roller 22, are mounted on the mounting frame 26, so that the mounting frame 26 drives the components to move laterally on the cross beam 24. The press roller driving element 27 is drivingly connected with the mounting frame 26 and drives the mounting frame 26 and the components, such as the press roller 22, on the mounting frame 26 to move on the cross beam 24. The anti-overlapping plate is arranged on one side of the press roller 22 to ensure the reliability of the stitching. Since two press rollers 22 are arranged in the embodiment, the mounting frame 26, the press roller driving element 27 and the anti-overlapping plate are also arranged with two, which are correspondingly matched to form two groups.

[0050] In the embodiment, the front processing device comprises a guide opening device 30, a cloth feeding device 40, a cutting device 50, a cutting conveying device 60, a pulling device 70 and a feeding conveying device 80.

The guide opening device 30 is rotatably arranged relative to the cutting device 50 to change the cutting angle of the cord fabric. The cutting conveying device 60 is connected with the cutting device 50 and conveys the cut cord fabric. A part of the cutting conveying device 60 can be located in the cutting device 50 to better receive the cord fabric. The pulling device 70 is located on one side of the cutting device 50 and the cutting conveying device 60. The pulling device 70 has double-axis pulling clamps to realize the pulling of the cord fabric with different angles and widths. The feeding conveying device 80 is connected with the cutting conveying device 60 and the joint conveying device 10 at both ends to convey the cut cord fabric to the joint conveying device 10.

[0051] In the embodiment, the rear processing device comprises a manual joint conveying belt 90, a slope unloading conveying belt 100, a balance roller device 110, a positive rubber sheet attaching device 120, a reverse rubber sheet attaching device 130 and a winding device 140.
