Technical Field

[0001] The utility model relates to the technical field of drum laminating machines, and particularly relates to a cord pressing and lifting device with adjustable angle. Background Art

[0002] Tire cord is a material used for manufacturing tires, usually made of nylon, polyester or other synthetic fibers. The main function of tire cord on the tire is to enhance the structural strength of the tire and prevent problems such as tire blowout during high-speed driving or under load; tire cord can also improve the wear resistance and durability of the tire and extend the service life of the tire. During the manufacturing process of tires, tire cord is usually covered on the carcass and assembled with components such as the carcass and tread to form a complete tire.

[0003] Tire cord is the material for forming the cord cylinder on the carcass. When manufacturing tires, the cord needs to be cut into cord sheets for covering the carcass according to the required size and shape without cutting the cord in the cord; and the cord angles in different cords are different. When cutting cords with different cord angles, it is necessary to adjust the angle of the cutting knife so that the plane where the cutting knife is located is parallel to the cord direction of the cord, and then cut the cord; during the process of cutting the cord, the movement of the cutting knife may drive the position of the cord to shift, and the cut cord sheet does not match the carcass, resulting in poor forming of the final cord cylinder and unable to meet the process requirements.

[0004] Therefore, how to design an angle-adjustable cord pressing and lifting device that can prevent the cord from shifting during the cutting process, resulting in poor forming of the final cord cylinder and unable to meet the process requirements, is a problem that existing equipment needs to solve.

[0042] The technical solution provided by the present invention has the following advantages:

[0043] 1. The cord fabric pressing and jacking device with adjustable angle of the present invention includes a first cross beam, a slewing bearing, a second cross beam, a first driving motor, guide rails, a left pressing frame, a right pressing frame and a cord fabric jacking device; wherein the first cross beam is suitable for being fixedly installed on a drum laminating machine; the top of the slewing bearing is fixedly connected to the bottom of the first cross beam; the top of the second cross beam is fixedly connected to the bottom of the slewing bearing and can rotate relative to the first cross beam through the slewing bearing; the first driving motor is fixedly installed on the first cross beam and has a first driving shaft, and a first driving gear is fixedly installed at the bottom end of the first driving shaft, and the first driving gear is meshed and connected with the slewing bearing; there are two guide rails, which are respectively fixedly arranged on the side walls on both sides of the second cross beam, and a cutter is suitable for being movably installed on the guide rails; the left pressing frame is fixedly installed on one side of the second cross beam, and a left pressing cylinder is installed at the bottom; the right pressing frame is fixedly installed on the other side of the second cross beam, and a right pressing cylinder is installed at the bottom.

After the cord fabric is lifted, the cord threads on the cord fabric are separated, and it is easier for the cutting knife to penetrate into the gap between the cord threads; then the cutting knife penetrates into the cord fabric and cuts it open to both sides to cut the cord fabric. When replacing the cord fabric with different cord thread angles and thus needing to adjust the cutting angle, the first driving motor is started, the first driving gear drives the slewing bearing to rotate, the slewing bearing drives the second cross beam to rotate, the second cross beam drives the cutting knife to rotate, and drives the left pressing frame and the right pressing frame to rotate synchronously until the plane where the cutting knife is located is parallel to the cord thread direction of the cord fabric; the angle of the cord fabric lifting device is also adjusted to be the same as the angle of the cutting knife, and then the replaced cord fabric is cut.

[0045] That is to say, for the cord fabric pressing and lifting device with adjustable angle of the present utility model, during the process of cutting the cord fabric, the cord fabric can be pressed and fixed to prevent the cutting knife from driving the cord fabric to shift.

[0067] The following will detail this application with reference to the drawings and in combination with embodiments. Embodiment

[0068] This embodiment provides an angle-adjustable curtain pressing and lifting device, as Figures 1-5 shown, including: a first cross beam 101, a slewing bearing 102, a second cross beam 103, a first driving motor 104, guide rails 107, a left pressing frame 307, a right pressing frame 308, and a curtain lifting device; wherein the first cross beam 101 is adapted to be fixedly installed on a drum laminating machine; the top of the slewing bearing 102 is fixedly connected to the bottom of the first cross beam 101; the top of the second cross beam 103 is fixedly connected to the bottom of the slewing bearing 102 and can rotate relative to the first cross beam 101 through the slewing bearing 102; the first driving motor 104 is fixedly installed on the first cross beam 101 and has a first driving shaft, and 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 and is used 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. A cutter 108 is adapted to be movably installed on the guide rail 107. In the initial state, the cutter 108 is located in the middle of the guide rail 107 in a combined state; the left pressing frame 307 is fixedly installed on one side of the second cross beam 103, and a left pressing cylinder 301 is installed at the bottom; the right pressing frame 308 is fixedly installed on the other side of the second cross beam 103, and a right pressing cylinder 304 is installed at the bottom; the curtain lifting device is arranged directly below the initial position of the cutter 108 and is used to lift the curtain to be cut; when the left pressing cylinder 301 and the right pressing cylinder 304 press downward, they press on both sides of the lifting device.

[0069] When using the angle-adjustable cord fabric pressing and lifting device of this embodiment, in the initial state, the cutting knife 108 is located in the middle of the guide rail 107 and in a combined state, and the cord fabric lifting device is arranged directly below the initial state of the cutting knife 108; when the cord fabric moves into place, the left pressing cylinder 301 and the right pressing cylinder 304 extend towards both sides of the cord fabric lifting device to press the cord fabric, and the cord fabric lifting device lifts the cord fabric to a certain height. After the cord fabric is lifted upwards, the cords on the cord fabric are separated, and it is easier for the cutting knife 108 to penetrate into the gap between the cords; then the cutting knife 108 penetrates into the cord fabric and cuts it open towards both sides (the cutting knife 108 includes two blades, which are combined in the middle in the initial state and have a piercing tip. After penetrating into the cord fabric, the two blades can be cut open towards both sides to cut off the cord fabric), and the cord fabric is cut off. When replacing the cord fabric with different cord angles and thus needing to adjust the cutting angle, the first driving motor 104 is started, 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 knife 108 to rotate, and drives the left pressing frame 307 and the right pressing frame 308 to rotate synchronously until the plane where the cutting knife 108 is located is parallel to the cord direction of the cord fabric; the angle of the cord fabric lifting device is also adjusted to be the same as the angle of the cutting knife 108, and then the replaced cord fabric is cut. The angle-adjustable cord fabric pressing and lifting device of this embodiment can press and fix the cord fabric during the cutting process of the cord fabric, avoid the cutting knife 108 driving the cord fabric to shift, and the shape of the cord fabric after cutting is regular, without causing poor forming of the cord fabric cylinder; in addition, when replacing the cord fabric with different cord angles, the angles of the cutting knife 108, the cord fabric lifting device, the left pressing cylinder 301 and the right pressing cylinder 304 are also adjusted synchronously, and the cord fabric can still be effectively pressed, lifted and cut.

[0070] When the left pressing cylinder 301 and the right pressing cylinder 304 press downwards, the connecting line of the pressing points is perpendicular to the cord direction of the cord fabric to be cut, which can better cooperate with the lifting device to press the cord fabric. After the cord fabric is lifted upwards, the cords on the cord fabric are separated, and it is easier for the cutting knife 108 to penetrate into the gap between the cords, avoiding the cutting knife 108 cutting the cords when penetrating into the cord fabric.

[0071] As Figures 6-7As shown in the figure, it further includes a planar limiting structure for limiting the rotation of the second crossbeam 103 within 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; among them, there are two first planar limiting members 113, which are fixedly arranged at the bottom of the first crossbeam 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, and 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 at the top of the second crossbeam 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, and the arc-shaped long convex blocks 119 can be matched and butted with the planar limiting groove 115; when the second crossbeam 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 crossbeam 103 within a plane. The setting of the above planar limiting structure can enable the second crossbeam 103 to rotate on the same horizontal plane without deviation in height, will not change the height position of the cutting tool 108, and also makes the adjustment of the cutting angle more accurate.

[0072] The left pressing frame 307 is fixedly installed between the two second planar limiting members 116 on one side of the second crossbeam 103 through the left pressing connecting plate 302; the right pressing frame 308 is fixedly installed between the two second planar limiting members 116 on the other side of the second crossbeam 103 through the right pressing connecting plate 303; this design can enable the left pressing frame 307 and the right pressing frame 308 to rotate synchronously with the second crossbeam 103, so that the left pressing cylinder 301 and the right pressing cylinder 304 always maintain the same rotation angle as the cutting tool 108.

[0074] The rotating motor 204 and the first driving motor 104 are linked through a control system (in this embodiment, a commonly used PLC control system in industry), so that the central plane of the cutting through slot 212 controlled by the rotating motor 204 and the central plane of the cutter in the initial state controlled by the first driving motor 104 are in the same plane, and this plane is parallel to the running direction of the cord in the cord fabric to be cut.

[0075] As Figure 10As shown, the jacking member 203 includes a jacking main body portion 210 and a jacking cutting portion 211. The jacking main body portion 210 is cylindrical, with an outer diameter smaller than the inner diameter of the operation through hole 202. The bottom end is fixedly connected to the rotating output shaft of the rotating motor 204 and can be driven to rotate. The bottom end of the jacking cutting portion 211 is fixedly connected to the top end of the jacking main body portion 210, and the outer diameter is larger than that of the jacking main body portion 210. A cutting through groove 212 is provided at the top end of the jacking cutting portion 211. At the middle position of the inner wall of the cutting through groove 212, an arc groove 213 extending in the vertical direction is provided, and the openings of the two arc grooves 213 provided on the two inner walls of the cutting through groove 212 face each other. A guiding inclined surface is formed at the top of the cutting through groove 212. The arc groove 213 is the position where the cutting tool enters the knife, which can facilitate the cutting tool to pierce the cord fabric, and the guiding inclined surface can guide the cutting tool to pierce the cord fabric more accurately.

[0076] As Figures 3-4 shown, the left pressing air cylinder 301 has a left telescopic rod 309, and a left pressing member 310 is sleeved at the end of the left telescopic rod 309. The free end of the left pressing member 310 is hemispherical. The right pressing air cylinder 304 has a right telescopic rod 311, and a right pressing member 312 is sleeved at the end of the right telescopic rod 311. The free end of the right pressing member 312 is hemispherical. The pressing member is made of a soft material, which can avoid pressing out grooves on the surface of the cord fabric due to excessive pressure. The free end is designed to be hemispherical without a tip, so it will not pierce the cord fabric.

[0077] The usage method of the angle-adjustable cord fabric pressing and jacking device in this embodiment is as follows:

[0078] First, according to the angle of the warp yarns on the cord fabric, start the first driving motor 104. The first driving motor 104 drives the slewing bearing 102 to rotate, and then drives the second cross beam 103 to rotate. The second cross beam 103 drives the cutting tool 108 to rotate through the guide rail 107, and drives the left pressing frame 307 and the right pressing frame 308 to rotate synchronously until the plane where the cutting tool 108 is located is parallel to the direction of the warp yarns on the cord fabric.

[0079] The left pressing air cylinder 301 and the right pressing air cylinder 304 extend to both sides of the cord fabric jacking device to press the cord fabric. The air cylinder 207 pushes the jacking fixing plate 205 to rise, and makes the jacking member 203 protrude from the operation through hole 202 to jack up the cord fabric to a certain height.

[0080] The combined cutting tool 108 moves downward simultaneously, pierces the cord fabric and then penetrates into the cutting through groove 212. The two openings at both ends of the cutting through groove 212 slide out respectively to cut off the cord fabric, and then the cutting tool 108 returns to the initial position.

[0081] When replacing the cord fabric with different cord angles and it is necessary to adjust the cutting angle, start the first drive motor 104 again. The first drive 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 cutter 108 to rotate and drives the left pressing frame 307 and the right pressing frame 308 to rotate synchronously until the plane where the cutter 108 is located is parallel to the cord direction of the cord fabric again, and then start cutting the cord fabric.

[0082] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of this innovative technical solution.
