[0002] In the tire manufacturing process, the nylon layer, as a reinforcing material for the cord fabric, is mainly used to improve the tire's strength and impact resistance. It is often laid between the tread and the belt layer. In the processing stage, a cutting device is often used to cut the large nylon cord fabric into multiple strips of fixed width.
[0003] Currently, common nylon layer cutting devices generally use multiple sets of fixed blade holders. The relative positions of the cutting blades and the corresponding guide wheels are set by mechanical structure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-4 This utility model provides an embodiment of an automatic blade adjustment device for cutting and slitting nylon layers, comprising a frame 1, a PLC control panel 2, a servo drive mechanism 3, a guide wheel assembly 4, a blade adjustment mechanism 7, a moving mechanism 6, and a cutting blade 8. The PLC control panel 2 is fixedly installed inside the left side of the front wall of the frame 1. The servo drive mechanism 3 includes a set of mounting brackets 302 fixedly installed on the top of the base 5. A geared motor 301 is installed on the outer wall of the mounting bracket 302, and a guide post 303 is fixedly connected to the mounting bracket 302. The guide wheel assembly 4 includes an electric slide rail 401 laid on the surface of the base 5. Multiple sets of slide rail movers 402 are embedded in the electric slide rail 401. A positioning plate 404 is welded to the right end of the slide rail mover 402. A bushing 405 is fixedly sleeved inside the positioning plate 404. 05 is sleeved on the outside of the guide post 303. The left side of the positioning plate 404 is rotatably connected to the cutting guide wheel 403. Multiple sets of positioning receivers 10 are installed on the top of the positioning plate 404. Each set of positioning receivers 10 corresponds to a set of cutting blades 8. The blade adjustment mechanism 7 is installed in the front area of the frame 1 and includes a linear guide rail 701 laid horizontally at the front end of the frame 1. Multiple sets of guide rail moving seats 702 are slidably connected in front of the linear guide rail 701. The moving mechanism 6 includes a blade holder 601 fixedly installed at the front end of the guide rail moving seat 702. Positioning sensors 9 are installed at the bottom of the blade holder 601. Each set of positioning sensors 9 corresponds to the position of its corresponding positioning receiver 10 in the vertical direction. The positioning plate 404 is a rectangular metal plate. The cutting guide wheels 403 are arranged one-to-one with the cutting blades 8 in the vertical direction.
[0020] Specifically, such as Figure 1, Figure 2 , Figure 3 and Figure 4 As shown, the linear guide rail 701 drives the guide rail moving seat 702 to move horizontally. Each set of cutter holders 601 moves synchronously with the guide rail moving seat 702. Each set of cutting cutters 8 moves synchronously with its corresponding positioning sensor 9. The positioning sensor 9 transmits a signal to the positioning receiver 10 in real time. By judging whether the positioning sensor 9 and the positioning receiver 10 are aligned, the cutting cutter 8 can automatically find and correct its position during the movement. The slide rail mover 402 also moves synchronously inside the electric slide rail 401, driving the positioning plate 404 to move as a whole. Finally, the cutting cutter 8 and the cutting guide wheel 403 are accurately aligned after adjustment. This structure does not require a rigid fixed connection between the cutting cutter 8 and the cutting guide wheel 403, avoiding transmission errors, reducing assembly complexity, improving the efficiency of cutter adjustment, ensuring the accuracy of cutting operations, and facilitating the synchronous and rapid cutting of multiple sets of nylon strip materials.
[0021] Furthermore, the linear guide 701 and the guide rail moving seat 702 adopt the mature electric slide structure available on the market. The linear guide 701 uses the HIWIN KK60 series electric module. The guide rail integrates a ball screw and a linear guide, and the screw is driven to rotate by a servo motor to realize the precise movement of the guide rail moving seat 702 along the X direction.
[0022] Furthermore, the electric slide rail 401 and the slide rail mover 402 also adopt a standardized ball screw type electric module, using the HIWIN KK100 series or TBI TRH20 linear module. The geared motor 301 is connected to the ball screw drive end inside the electric slide rail 401 through a coupling. The slide rail mover 402 is controlled by its built-in servo motor, so that the slide rail mover 402 drives the cutting guide wheel 403 to move smoothly along the Y direction, realizing the synchronous alignment adjustment of multiple cutting guide wheels 403 as a whole.
[0023] Furthermore, both sets of electric modules are connected to the PLC control panel 2 for unified management, enabling functions such as multi-point positioning, program setting, and adaptive correction.
[0024] Specifically, such as Figure 1 and Figure 4 As shown, the movement of the slide rail mover 402 is controlled by the servo drive mechanism 3. The geared motor 301 installed in the servo drive mechanism 3 outputs power to the electric slide rail 401, and the slide rail mover 402 moves back and forth, thereby adjusting the relative distance between the positioning plate 404 and its upper cutting guide wheel 403, so as to realize the rapid adjustment of the guide wheel assembly 4.
[0025] The tool adjusting mechanism 7 also includes a lifting cylinder 703, which is fixedly installed inside the guide rail moving seat 702. A connecting seat 704 is fixedly sleeved on the piston rod of the lifting cylinder 703, and the right end of the connecting seat 704 is fixedly connected to the tool holder 601.
[0026] Specifically, such as Figure 1 and Figure 2 As shown, a lifting cylinder 703 is fixedly installed inside the guide rail moving seat 702. The piston rod of the lifting cylinder 703 is externally fixedly sleeved with a connecting seat 704. The right end of the connecting seat 704 is fixedly connected to the knife holder 601. When the lifting cylinder 703 is ventilated, the piston rod extends or retracts, driving the connecting seat 704 and the knife holder 601 on it to rise and fall as a whole, thereby driving the cutting knife 8 to move up and down. When the knife descends, it performs the cutting action, and when the knife rises, it achieves the knife retraction to avoid idling or scratching the surface of the strip.
[0027] Furthermore, vertical guides such as guide wires can be fixedly installed on both sides of the guide rail moving seat 702 to make the connecting seat 704 rise and fall stably along its guide trajectory, thereby improving the smoothness of operation.
[0028] Furthermore, the upper part of the front wall of the guide rail moving seat 702 is provided with a step 705. The step 705 matches the front shape of the tool holder 601. During the upward movement of the tool holder 601, the step 705 limits the position at a specific location to prevent the tool holder 601 from exceeding the preset height, thereby improving the structural compactness and operational safety.
[0029] The moving mechanism 6 also includes a moving cylinder 604 fixedly installed inside the knife holder 601. The piston rod of the moving cylinder 604 is fixedly connected to the knife holder 603. The knife holder 603 covers the outside of the cutting knife 8. The right side wall of the knife holder 601 is fixedly connected to the knife motor 602. The knife motor 602 is fixedly connected to the shaft of the cutting knife 8 through a coupling and is used to drive the cutting knife 8 to rotate. The front wall of the guide rail moving seat 702 is machined with a step 705 near the upper position. The knife holder 601 and the step 705 are matched in shape to limit the lifting stroke of the knife holder 601.
[0030] Specifically, such as Figure 1 and Figure 2 As shown, a movable cylinder 604 is fixedly installed inside the blade holder 601. The front end of the piston rod of the movable cylinder 604 is fixedly connected to the blade holder 603. The blade holder 603 is covered outside the cutting blade 8. After the movable cylinder 604 is ventilated, it can drive the blade holder 603 to make a small range of lateral displacement, thereby driving the cutting blade 8 to make fine adjustments in the left and right directions, realizing a higher precision compensation positioning function than the guide rail movable seat 702, and improving the cutting accuracy.
[0031] Specifically, such as Figure 1 and Figure 2 Figure 1 Figure 2As shown, a cutter motor 602 is fixedly connected to the right side wall of the cutter holder 601. The cutter motor 602 is fixedly connected to the central shaft of the cutting blade 8 through a coupling. When the cutter motor 602 is powered on and started, the cutting blade 8 rotates at high speed to complete the cutting process of the nylon layer material. This structure is simple and the power transmission is direct, making it suitable for continuous cutting and variable pitch blade adjustment.
[0032] Working principle: The operator inputs control commands through the PLC control panel 2, the servo drive mechanism 3 starts the geared motor 301, the slide rail mover 402 on the electric slide rail 401 reciprocates within the slide rail, thereby driving the overall displacement of the positioning plate 404, realizing the synchronous adjustment of the cutting guide wheel 403, aligning it with the target cutting position, the linear guide rail 701 in the knife adjustment mechanism 7 drives the guide rail moving seat 702 to move along the X direction, driving the knife holder 601 and the cutting knife 8 to perform lateral adjustment, the positioning sensor 9 at the bottom of the knife holder 601 transmits signals in real time and performs alignment recognition with the positioning receiver 10. The system enables adaptive correction of the position of each cutting blade 8 corresponding to the cutting guide wheel 403, achieving precise positioning. After the adjustment is completed, the lifting cylinder 703 pushes the connecting seat 704 and the blade holder 601 to move down as a whole, so that the cutting blade 8 is pressed down to the surface of the nylon layer material to perform cutting. After cutting, the blade automatically rises and exits the cutting area to avoid interference. If fine adjustment is required, the moving cylinder 604 can also drive the blade holder 603 to shift left and right, and cooperate with the linear guide rail 701 to achieve higher precision blade adjustment control. After the blade motor 602 is started, it drives the cutting blade 8 to rotate at high speed through the coupling to achieve the cutting of the nylon layer.
[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
