Description

Technical Field

[0001] The utility model relates to the technical field of drum laminating machines, and particularly relates to a cord fabric lifting device and a cord fabric cutting device which can cooperate with a cutting knife to cut the cord fabric. Background Art

[0002] The cord fabric cylinder for producing tires is the skeleton material of the tire, accounting for about 10%-15% of the total weight of the outer tire, and has a great influence on the performance and service life of the tire. The cord fabric cylinder of the tire is usually formed by hot pressing and bonding multiple layers of cord fabric, which plays a role in increasing the overall strength of the tire and stabilizing the outer tire; the cord yarn contained in the cord fabric has a high technical content, and has high requirements for the strength, stretchability, elastic modulus of the fiber, the adhesiveness with rubber, fatigue resistance, dimensional stability, heat resistance and impact resistance, etc. Its raw materials include nylon, polyester, viscose filament, para-aramid and steel wire, etc.

[0003] When producing the cord fabric cylinder of bias tires, the cutting angle of the cord fabric is directly related to the quality of the cord fabric cylinder.

[0057] The technical solution provided by the present utility model has the following advantages:

[0058] 1. The cord fabric jacking device of the present utility model includes an operation board, a jacking mounting board, a jacking fixing board, a rotating motor, a jacking member, and a jacking cylinder.

The jacking mounting board is adapted to be fixedly mounted on the drum laminating machine and is located below the operation board. The jacking fixing board is located between the operation board and the jacking mounting board, with a jacking through-hole opened in the middle. The rotating motor is fixedly mounted below the jacking fixing board and has a rotating output shaft, and the position of the rotating output shaft is vertically opposite to the position of the jacking through-hole. The bottom of the jacking member is fixedly connected to the rotating output shaft, and a cutting through-slot is opened at the top.

[0059] When using the cord fabric jacking device of the present utility model in cooperation with a cutter to cut the cord fabric, in the initial state, the jacking member does not protrude from the operation through-hole. When the cord fabric moves into place, the jacking cylinder pushes the jacking fixing board to rise, and the jacking member protrudes from the operation through-hole to jack up the cord fabric by a certain height. Then, the cutter is started. After the combined cutter pierces the cord fabric, it slides out from the two ends of the cutting through-slot and moves in opposite directions to cut the cord fabric. When the angle of the cutter changes due to replacing the cord fabric with different cord angles, the rotating motor is started.

[0062] When cutting the cord fabric with the cord fabric cutting device of the present utility model, in the initial state, the two cutters are in a fitting state, and a piercing tip is formed at the bottom, which is opposite to the middle of the cutting through hole of the cord fabric jacking device; when the cord fabric needs to be cut, the jacking cylinder pushes the jacking fixing plate to rise, so that the jacking part protrudes out of the working through hole to jack up the cord fabric to a certain height, and the piercing tips of the two cutters in the fitting state pierce down through the cord fabric and enter the inside of the cutting through hole, and the driving structure drives the two cutters to move away from each other and slide out from the cutting through hole, and cut the cord fabric; when the cord fabric cutting is completed, the jacking cylinder drives the jacking fixing plate to fall back, so that the top end of the jacking part is basically flush with the working through hole, and the two cutters return to the initial state through the driving structure. When replacing the cord fabric with different cord angles and thus needing to adjust the cutting angle, start the first driving motor, the first driving gear drives the slewing bearing to rotate, the slewing bearing drives the second cross beam to rotate, and the second cross beam drives the cutter to rotate until the plane where the cutter is located is parallel to the cord direction of the cord fabric; then start the rotating motor of the cord fabric jacking device, the rotating motor drives the jacking part to rotate so that the angle of the cutting through hole is the same as the angle of the cutter, and then cut the cord fabric.

The first driving motor 104 is fixedly installed on the first cross beam 101 and has a first driving shaft. A first driving gear 106 is fixedly installed at the bottom end of the first driving shaft. The first driving gear 106 is meshed with the slewing bearing 102 to drive the slewing bearing 102 to rotate. There are two guide rails 107, which are respectively fixedly arranged on the side walls on both sides of the second cross beam 103. The first cutting knife 131 and the second cutting knife 139 are respectively movably installed on the guide rails 107 located on both sides of the second cross beam 103. The plane where the two cutting knives 108 are located always remains parallel to the vertical plane where the axis of the second cross beam 103 is located. The driving structure is used to drive the two cutting knives 108 to approach or move away from each other on the guide rails 107. In the initial state, the two cutting knives 108 are in a fitting state, and a piercing tip is formed at the bottom, which is opposite to the middle of the cutting through groove 212 of the cord fabric jacking device. When it is necessary to cut the cord fabric, the piercing tips of the two cutting knives 108 in the fitting state pierce down through the cord fabric and enter the inside of the cutting through groove 212. The driving structure drives the two cutting knives 108 to move away from each other and slide out of the cutting through groove 212 to cut the cord fabric. When the cord fabric cutting is completed, the two cutting knives 108 return to the initial state through the driving structure.

[0088] When cutting the cord fabric using the cord fabric cutting device of this embodiment, in the initial state, the two cutting blades 108 are in a fitting state, forming a piercing tip at the bottom, which is opposite to the middle of the cutting through slot 212 of the cord fabric lifting device; when it is necessary to cut the cord fabric, the lifting cylinder 207 pushes the lifting fixing plate 205 to rise, so that the lifting member 203 protrudes from the operation through hole 202 to lift the cord fabric to a certain height. The piercing tips of the two cutting blades 108 in the fitting state pierce the cord fabric downward and enter the inside of the cutting through slot 212. The driving structure drives the two cutting blades 108 to move away from each other and slide out from the cutting through slot 212, and cuts the cord fabric; when the cord fabric cutting is completed, the lifting cylinder 207 drives the lifting fixing plate 205 to fall back, so that the top end of the lifting member 203 is basically flush with the operation through hole 202, and the two cutting blades 108 return to the initial state through the driving structure. When replacing the cord fabric with different cord angles and thus needing to adjust the cutting angle, start the first driving motor 104. The first driving gear 106 drives the slewing bearing 102 to rotate. The slewing bearing 102 drives the second cross beam 103 to rotate. The second cross beam 103 drives the cutting blade 108 to rotate until the plane where the cutting blade 108 is located is parallel to the cord direction of the cord fabric; then start the rotating motor 204 of the cord fabric lifting device. The rotating motor 204 drives the lifting member 203 to rotate so that the angle of the cutting through slot 212 is the same as the angle of the cutting blade 108, and then cuts the cord fabric.

[0089] As Figures 5-8 shown, it further includes a planar limiting structure for limiting the rotation of the second cross beam 103 in a plane; the planar limiting structure includes a first planar limiting member 113, a planar limiting roller 114, a second planar limiting member 116 and a planar limiting arc track 117; where there are two first planar limiting members 113, which are fixedly arranged at the bottom of the first cross beam 101 and are located on both sides of the slewing bearing 102; there are several pairs of planar limiting rollers 114, which are fixedly arranged at the bottom of the first planar limiting member 113. A planar limiting groove 115 with a V-shaped cross section is relatively formed in the middle of any pair of the planar limiting rollers 114; there are two second planar limiting members 116, which are fixedly arranged on the top of the second cross beam 103 and are arranged up and down opposite to the first planar limiting member 113; the planar limiting arc track 117 is fixedly arranged on the second planar limiting member 116, and arc-shaped long convex blocks 119 with a V-shaped cross section are formed on both sides of the top surface. The arc-shaped long convex blocks 119 can be matched and docked with the planar limiting groove 115; when the second cross beam 103 rotates, the planar limiting roller 114 limits the rotation of the planar limiting arc track 117 through the planar limiting groove 115, and further limits the rotation of the second cross beam 103 in a plane. The setting of the above planar limiting structure can make the second cross beam 103 rotate on the same horizontal plane without tilting in height, will not change the height position of the cutting blade 108, and also makes the adjustment of the cutting angle more accurate.

There are two second cutter head docking members 146, which are respectively fixedly arranged on the second cutter head connecting member 127 and the second cutter head moving member 143 and can be matched and docked with the first cutter head docking member 138. After the second cutter head docking member 146 is matched and docked with the first cutter head docking member 138, the first cutter head 137 and the second cutter head 145 are in a fitting side-by-side state.

[0092] A triangular protrusion is formed on the first cutter head docking member 138. There are two second cutter head docking members 146, both of which are formed with triangular grooves.
