Description

Technical Field

[0001] The invention relates to radial tire production equipment, in particular to a steel cord cutting device. Background Art

[0002] The carcass cord or belt cord of the radial tire of the related art needs to be cut, spliced, and wrapped on the cutting production line before being rewound into a cord roll for use by the tire forming machine. The cutting device of the cutting production line is responsible for cutting the cord into cord strips of fixed length, and the cut cord strips are received by the conveyor belt and sent to the subsequent splicing device of the production line. In the related art, the cord strips are delivered and fixed in length through a four-bar mechanism and a magnetic beam set at the delivery end, and are cut by upper and lower knives, and the conveyor belt is used to receive the cut cord strips.

[0003] However, in the C-shaped cutting device of the cutting production line, the cutter gap is adjusted at a single point, and the gap amount is difficult to control. It is often adjusted inappropriately or the interference is large, resulting in chipping of the blade and even causing the cutter to be scrapped.

[0004] In the Z-shaped cutting device of the cutting production line, the cutting device includes an upper cutting knife mechanism and a lower cutting knife mechanism. The upper cutting knife mechanism includes an upper knife holder, an upper knife installed on the upper knife holder, and an upper knife driving mechanism. The upper knife driving mechanism includes a main transmission and a connecting rod. The main transmission drives the upper knife holder to move up and down through the connecting rod, thereby realizing the up and down movement of the upper knife. The lower cutting knife mechanism includes a frame, a movable workbench, a lower knife installed on the movable workbench, and an adjusting screw. The movable workbench is fixed to the frame by an adjusting screw. There are three adjusting screws, which are respectively located in the middle and at both ends of the movable workbench. A dial indicator is installed on the movable workbench to observe the dial indicator. The movable workbench is driven to move by turning the nut to adjust the adjusting screw, so that the lower knife fixed on the movable workbench moves to adjust the gap between the upper and lower knives.

[0005] The smaller the gap is, the smoother the upper and lower knives can cut, and the larger the gap is, the more difficult it is for the upper and lower knives to cut. When the upper and lower gaps need to be adjusted when replacing or adjusting the lower knife, the gap displayed by the dial indicator is not accurate, so the screw cannot be adjusted properly or the gap displayed by the dial indicator is too large, resulting in blind adjustment of the screw.

Since the screw and the elastic member are coaxially arranged, the point of action of the elastic force surrounds the screw, so that the preload force on the screw is more uniform, avoiding the phenomenon that the points of action of the elastic force in the related art are all located on one side of the adjusting screw, causing the axis of the adjusting screw to tilt relative to the movable workbench, resulting in inaccurate gap amount displayed by the dial indicator.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0030] like Figures 1 to 4 As shown, the cutting device of the steel cord fabric of this embodiment includes: a frame 10, an upper cutting mechanism, a lower cutting mechanism, an adjustment mechanism and a display instrument assembly 50. The upper cutting mechanism is arranged on the frame 10, and the upper cutting mechanism includes an upper cutting frame 21 and an upper knife 22 arranged on the upper cutting frame 21. The lower cutting mechanism is arranged on the frame 10 and is located below the upper cutting mechanism. The lower cutting mechanism includes a knife plate 31 movably arranged on the frame 10 and a lower knife 32 connected to the knife plate 31. In the moving direction (such as Figure 1 The upper knife 22 and the lower knife 32 have a cutting gap H between them. The adjusting mechanism is arranged on the knife plate 31 and connected to the frame 10. The adjusting mechanism includes a first mounting hole (not shown in the figure), a screw hole (not shown in the figure), a screw rod 43, an elastic member 44 and a first nut 45 which are coaxially arranged. The first mounting hole is arranged on the knife plate 31, the screw hole is arranged on the frame 10, and there is an adjustment gap between the knife plate 31 and the frame 10. The screw rod 43 is inserted into the first mounting hole and the screw hole, and the elastic member 44 and the first nut 45 are in the adjustment gap and sleeved on the screw rod 43. The first nut 45 squeezes the elastic member so that the elastic member 44 applies elastic force to the knife plate 31, and the screw rod 43 is turned to drive the knife plate 31 to move so as to adjust the size of the adjustment gap and thus adjust the size of the cutting gap H. The display instrument assembly 50 is arranged on the knife plate 31 and abuts against the frame 10.

[0031] The technical solution of this embodiment is applied, and the adjustment mechanism includes a first mounting hole, a screw hole, a screw rod 43, an elastic member 44 and a first nut 45 which are coaxially arranged. The first mounting hole is arranged on the blade plate 31, and the screw hole is arranged on the frame 10. There is an adjustment gap between the blade plate 31 and the frame 10. The screw rod 43 is inserted into the first mounting hole and the screw hole. The elastic member 44 and the first nut 45 are in the adjustment gap and sleeved on the screw rod 43. The above adjustment gap is convenient for placing the elastic member and the first nut 45. In the present application, the first nut 45 squeezes the elastic member so that the elastic member 44 applies elastic force to the blade plate 31. Since the screw rod 43 and the elastic member 44 are coaxially arranged, the action point of the elastic force surrounds the screw rod 43, so that the pre-tightening force on the screw rod 43 is more uniform, avoiding the phenomenon that the action points of the elastic force in the related art are all located on one side of the adjusting screw rod, so that the axis of the adjusting screw rod is tilted relative to the movable workbench, resulting in inaccurate gap amount displayed by the dial indicator. At the same time, the elastic member 44 applies elastic force to the knife plate 31, which can also effectively reduce the active gap between the screw rod 43 and the first mounting hole, and effectively reduce the matching error. The screw rod 43 is turned to drive the knife plate 31 to move to adjust the size of the adjustment gap and then adjust the size of the cutter gap H. The adjustment amount of the adjusted cutter gap can be clearly and reliably displayed through the numerical display of the display instrument assembly 50. Therefore, the technical solution of this embodiment effectively solves the problem that the gap amount displayed by the dial indicator in the related art is inaccurate, resulting in blind adjustment of the screw rod.

[0032] It should be noted that the driving force of the screw 43 to drive the blade 31 to move is greater than the elastic force applied by the elastic member 44 to the blade 31, and the screw 43 can move along the first nut 45 relative to the first nut 45. Figure 1 Move in the direction of the arrow shown to the right.

[0033] In addition, the inventors discovered that the movable workbench of the related technology includes an upper side portion and a lower side portion, the lower knife is connected to the upper side portion, and the adjusting screw is arranged on the lower side portion. At this time, when the adjusting screw is used to adjust the gap between the upper and lower knives, screwing the adjusting screw will cause a torque to be generated between the adjusting screw and the upper side portion, causing the movable workbench to shake, resulting in inaccurate display values ​​of the dial indicator, and thus failing to accurately adjust the gap between the upper and lower knives.

[0034] like Figure 3As shown, in this embodiment, the axis of the first mounting hole is located within the center plane Y in the thickness direction of the blade 31. The distance from the center plane Y to the upper surface of the blade 31 is equal to the distance from the center plane Y to the lower surface of the blade 31. In this way, the extrusion force applied by the screw 43 to the blade 31 is within the center plane Y, and no torque is generated, thereby preventing the blade 31 from shaking. At the same time, the elastic force applied by the elastic member 44 to the blade 31 and the extrusion force applied by the screw 43 to the blade 31 can be partially offset, so that the screw 43 can drive the blade 31 to move more reliably and stably. Therefore, the above-mentioned setting method can solve the problem that the display value of the dial indicator is inaccurate, resulting in the inability to accurately adjust the gap between the upper and lower knives.

[0035] like Figure 3 and Figure 5 As shown, in this embodiment, the adjustment mechanism also includes a bearing 46 inserted into the first mounting hole and a retaining ring 47 located in the adjustment gap, and the retaining ring 47 is sandwiched between the elastic member 44 and the bearing 46. The setting of the bearing 46 can reduce the friction coefficient between the screw 43 and the first mounting hole, and the rotation of the adjustment screw 43 becomes smoother. The setting of the retaining ring 47 can provide a supporting plane to prevent the elastic force applied by the elastic member 44 to the blade 31 from tilting. The bearing 46 of this embodiment is preferably an axial bearing, and there are two axial bearings, which are respectively arranged at the two ends of the first mounting hole.

[0036] like Figure 3 and Figure 5 As shown, in this embodiment, the frame 10 includes a frame body 11 and a second nut 12 disposed on the frame body 11, and the inner hole of the second nut 12 forms a screw hole. The second nut 12 has a simple structure, low cost, and is easy to obtain. The screw rod 43 includes a bare rod section that cooperates with the first mounting hole, a first threaded section that cooperates with the first nut 45, and a second threaded section that cooperates with the screw hole. Different functions can be realized on such a screw rod 43, which can reduce costs.

[0037] like Figure 3 and Figure 5 As shown, in this embodiment, the elastic member 44 includes a plurality of disc springs. Compared with springs, disc springs have high strength and small deformation, and the force of the first nut 45 squeezing the elastic member 44 is not easy to cause tilting, and the error generated is small.

[0038] like Figures 4 to 6 As shown, in this embodiment, the knife plate 31 includes a first side portion 311 and a second side portion 312 that are arranged opposite to each other, and the adjustment mechanism includes a first adjustment mechanism and a second adjustment mechanism. The first adjustment mechanism is arranged at the first side portion 311, and the second adjustment mechanism is arranged at the second side portion 312. The first adjustment mechanism and the second adjustment mechanism can balance the reverse force applied by the knife plate 31 to the adjustment mechanism, and the cutting gap H can be easily adjusted, so that the adjustment is simple and the auxiliary time can be shortened.

[0039] like Figure 4 As shown, in this embodiment, there are multiple display instrument assemblies 50 and multiple adjustment mechanisms, and the multiple display instrument assemblies 50 are arranged one by one with the multiple adjustment mechanisms. In this way, the adjustment amount of the cutter gap H adjusted by each adjustment mechanism can be accurately displayed by the display instrument assembly 50, and the adjustment error can be reduced as much as possible. The display instrument assembly 50 includes a dial indicator or a micrometer. In this way, the value of the smaller deformation of the cutter gap H can also be accurately obtained.

[0040] like Figure 1 and Figure 4 As shown, in the present embodiment, the cutting device for the steel cord fabric further includes a second mounting hole provided on the knife plate 31, a third mounting hole provided on the frame 10, a fastener 61 inserted into the second mounting hole and the third mounting hole, and a third nut connected to the fastener 61. The third mounting hole is an elongated hole provided along the moving direction of the knife plate 31, a part of the fastener 61 is connected to the second mounting hole, and another part of the fastener 61 is movably inserted into the third mounting hole. In the present embodiment, the fastener 61 is preferably a bolt, and tightening the third nut on the bolt can fix the knife plate 31 on the frame 10, and the third nut is turned to loosen the bolt. At this time, when the knife plate 31 moves on the frame 10, another part of the fastener 61 moves in the elongated hole, so that the cutting gap H can be easily adjusted. It should be noted that in Figure 1 In the directions of the up and down arrows shown, the third nut is located below the frame 10 .

[0041] like Figure 3 As shown, in this embodiment, the frame 10 includes a frame body 11 and a stopper 13 disposed on the frame body 11. The display instrument assembly 50 includes a support frame 51 disposed on the blade 31, a display unit 52 connected to the support frame 51, and a push rod 53 movably disposed on the display unit 52. The support frame 51 is convenient for fixing the display unit 52 on the frame body 11. The push rod 53 is in abutment with the stopper 13. The surface where the stopper 13 and the push rod 53 are in abutment with each other is finely processed, so that the value measured by the display unit 52 is more accurate.

[0042] like Figure 4As shown, the blade plate 31 includes a plate body 313 and a lower blade seat 314 disposed on the plate body 313, the lower blade 32 is disposed on the lower blade seat 314, and the cutting device for the steel cord fabric also includes a first bolt 63 and a second bolt 64 connected to the plate body 313. The cutting device for the steel cord fabric also includes a gasket 65 disposed between the lower blade seat 314 and the plate body 313. The first bolt 63 is inserted into the gasket 65 to press the lower blade seat 314, and the second bolt 64 includes a connecting end connected to the plate body 313 and an abutting end abutting against the lower blade seat 314. The first bolt 63 is located on both sides of the second bolt 64. The first bolt 63 can pull the lower blade seat 314. Under the joint action of the first bolt 63, the gasket 65 and the second bolt 64, the projection of the lower blade 32 on the blade plate 31 is in a convex arc shape. In this way, when the lower blade 32 and the upper blade 22 are cut, the deformation of the lower blade 32 can be reduced. The above structure can improve the production capacity of cutting parts and increase the service life of the lower knife 32 and the upper knife 22.

[0043] like Figure 1 , Figure 4 and Figure 5 As shown, the cutting device for steel cord fabric further includes a main transmission mechanism 71 for driving the upper knife holder 21 to move and a brake mechanism 72 for braking the upper knife holder 21, so that the upper knife 22 can be moved in an inching manner. The cutting device for steel cord fabric further includes a material pressing mechanism 73, a connecting rod mechanism 74, a fourth nut 75 and a pressing plate 76 arranged on the upper knife holder 21. The main transmission mechanism 71 drives the upper knife holder 21 to move through the connecting rod mechanism 74. The fourth nut 75 is used to fix the lower knife seat 314 on the plate body 313. The pressing plate 76 cooperates with the fastener 61 to movably connect the knife plate 31 to the frame 10.

[0044] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0045] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0046] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
