Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically to a tire cord fabric cutting device. Background Technology

[0002] Tire cord fabric is the skeleton material of a tire. It is mainly woven from high-strength yarns as warp and medium- and fine-count single yarns as weft. The warp yarns are tightly arranged, while the weft yarns are sparsely arranged, resembling a curtain, hence the name. During tire manufacturing, a layer of rubber is applied and a layer of fabric is wrapped around it to form the tire shape. The cord fabric layer mainly serves to strengthen the tire, protecting the rubber, resisting tensile stress, and withstanding enormous pressure, impact loads, and strong vibrations, greatly affecting the tire's performance and lifespan.

[0003] When tire cord fabric is produced, it needs to be cut. However, the usual method of cutting cord fabric is to lay it out and then transport it for cutting. This can easily cause the cord fabric to deviate during the transport process, resulting in the cutting of the cord fabric being off-center. At the same time, a large amount of flying debris is generated during the cutting process. If workers inhale it, it will cause harm to their health. Utility Model Content

[0004] The purpose of this invention is to provide a tire cord fabric cutting device that can cut the cord fabric body into different widths as needed, preventing deviation, and collecting the scattered debris generated during cutting to prevent inhalation and health hazards. This invention solves the problems of conventional cord fabric cutting, which involves laying the cord fabric out and then conveying it for cutting, which is prone to deviation during the conveying process, causing the cord fabric to be cut off. It also addresses the issue that during the cutting process, a large amount of scattered debris is generated, which can be inhaled by workers and cause health hazards.

[0023] 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.

[0024] Please see Figures 1 to 7 The present invention provides two embodiments:

[0025] Example 1: A tire cord fabric cutting device includes a workbench 2 and a pipe 23. A turntable 8 is rotatably connected to the upper surface of the workbench 2. A rotating rod 15 is fixed on the upper surface of the turntable 8. The rotating rod 15 is inserted into a take-up roller 11. Cord fabric body 13 is wound around the outer wall of the take-up roller 11. A bracket 3 is fixed on the upper surface of the workbench 2. A groove 17 is opened at the front end of the bracket 3. A hydraulic cylinder 5 is installed on the upper surface of the bracket 3. A hydraulic rod 6 is installed at the bottom end of the hydraulic cylinder 5. A cylindrical barrel 20 is fixed at the bottom end of the hydraulic rod 6.

[0026] Hydraulic cylinder 5: Composed of cylinder barrel, piston, seals, end caps, etc., it is the actuator of the hydraulic system. Hydraulic rod 6: Piston rod: One end is connected to the piston, and the other end extends out of the cylinder barrel, used to transmit force and motion. The working principle of hydraulic cylinder 5 is that the pressure of hydraulic oil pushes the piston to move, thereby driving the hydraulic rod 6 to extend or retract, realizing linear motion. The specific process is as follows: a. Hydraulic oil enters hydraulic cylinder 5: When the hydraulic pump presses hydraulic oil into one side of hydraulic cylinder 5, such as the rodless chamber, the pressure of the oil acts on the piston. According to Pascal's principle, the pressure of the liquid is evenly transmitted to the entire surface of the piston, generating thrust. b. Piston movement: The piston begins to move under the push of the hydraulic oil, driving the hydraulic rod 6 to extend or retract. If the hydraulic oil enters the rodless chamber, the piston rod extends; if the hydraulic oil enters the rod chamber, the piston rod retracts. c. Force transmission: The thrust of the piston is transmitted to the external load through the hydraulic rod 6 to complete the work such as lifting, pushing and pulling. d. Oil return process: When the hydraulic oil flows out from the other side, such as the rod chamber, the piston moves in the opposite direction, and the hydraulic rod 6 retracts or extends. The oil returns to the oil tank through the return oil line of the hydraulic system, completing one working cycle.

[0027] A circular groove 19 is formed on the lower surface of the cylindrical barrel 20. A circular groove 21 is formed at the top of the inner wall of the circular groove 19. A through groove 24 is formed on one side of the outer wall of the cylindrical barrel 20. A long plate 7 is fixed on one side of the outer wall of the cylindrical barrel 20. A long groove 31 is formed on the upper surface of the long plate 7. A connecting block 27 is inserted into the long groove 31. A movable plate 26 is fixed on the upper surface of the connecting block 27. A cutter 25 is fixed on one side of the movable plate 26. The cutter 25 extends into the circular groove 21 through the through groove 24.

[0028] Four pillars 1 arranged in a rectangular array are fixed on the lower surface of the workbench 2;

[0029] A circular hole 10 is provided on the lower surface of the worktable 2. A motor 9 is fixed on the lower surface of the worktable 2. The top end of the transmission shaft of the motor 9 extends into the circular hole 10. A turntable 8 is fixed on the top end of the transmission shaft of the motor 9.

[0030] The front and rear ends of the rotating rod 15 are respectively fixed with insert plates 16. The upper surface of the winding roller 11 is provided with an insertion hole 14. The front and rear ends of the inner wall of the insertion hole 14 are respectively provided with slots 12. The rotating rod 15 is inserted into the insertion hole 14, and the insert plate 16 is inserted into the slot 12.

[0031] The upper surface of the bracket 3 has a second round hole 18, and the bottom end of the hydraulic rod 6 installed in the hydraulic cylinder 5 extends through the second round hole 18 and into the groove 17.

[0032] A threaded hole 32 is provided on one side of the connecting block 27, and a round hole 30 is provided on one side of the long plate 7. A motor 29 is fixed on one side of the long plate 7. One side of the drive shaft of the motor 29 extends into the round hole 30. A screw 28 is fixed on one side of the drive shaft of the motor 29. One side of the screw 28 passes through the threaded hole 32 and is threadedly connected.

[0033] Motor 29 is a servo motor, which can rotate in both directions as needed, allowing the cutter 25 to move back and forth as required, facilitating the cutting of the curtain fabric body 13. The servo motor operates as follows: before a control signal is issued, the rotor remains stationary; when the control signal is issued, the rotor immediately rotates; when the control signal disappears, the rotor stops instantly. This rotation and the number of pulses issued form a closed-loop relationship, enabling the system to accurately track and control the motor's rotation.

[0034] In this embodiment, when the tire cord fabric needs to be cut, the cord fabric body 13 is wound onto the take-up roller 11, the rotating rod 15 is inserted into the insertion hole 14, and the insertion plate 16 is inserted into the slot 12. The hydraulic cylinder 5 is activated, causing the hydraulic rod 6 to extend and retract, and the cylinder 20 moves up and down to a suitable height. At the same time, the cord fabric body 13 extends into the circular groove 21 through the circular groove 19. The motor 9 is activated, causing the turntable 8, the take-up roller 11, and the cord fabric body 13 to rotate. Finally, the motor 29 is activated, causing the screw 28 to rotate. The connecting block 27, the moving plate 26, and the cutter 25 can be moved as needed. The cutter 25 cuts the cord fabric body 13, achieving the effect of cutting the cord fabric body 13 into different widths as needed and preventing displacement.

[0035] Example 2:

[0036] A mounting hole 22 is provided on one side of the upper surface of the cylindrical barrel 20. A pipe 23 is inserted into the mounting hole 22 and fixed in place. A flexible hose 4 is sleeved on the upper end of the pipe 23.

[0037] The diameter of the circular groove 19 opened in the cylindrical barrel 20 is larger than the diameter of the curtain fabric body 13, and the circular groove 19 opened in the cylindrical barrel 20 is vertically aligned with the center of the curtain fabric body 13.

[0038] The diameter of the first circular groove 19 is larger than the diameter of the curtain fabric body 13, which makes it easier for the top of the curtain fabric body 13 to extend into the second circular groove 21 through the first circular groove 19, so as to facilitate cutting the curtain fabric body 13 into different widths, and at the same time, it is easy to collect the scattered debris generated during cutting.

[0039] In this embodiment, when the curtain fabric body 13 is cut, the curtain fabric body 13 extends into the circular groove 21 through the circular groove 19. When the cutter 25 cuts the curtain fabric body 13, a large amount of flying debris is generated. The hose 4 is connected to a vacuum cleaner, which can suck up and collect the flying debris, thus achieving the effect of collecting the flying debris generated during cutting and preventing it from being inhaled and causing health damage.

[0040] 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.
