Description

Technical Field

[0001] This utility model relates to the field of reed processing technology, specifically a reed stamping machine. Background Technology

[0002] The reed is the core component of the steel reed on a loom. It is made of thin metal sheets and is shaped like a blade. The warp threads pass through the teeth of the reed. Its main function is to push the weft threads to the weft end. It can also control the arrangement density of the warp yarns and the width of the fabric. It plays a key role in the structure and appearance of the fabric during the weaving process. Stainless steel has good corrosion resistance, wear resistance and strength. It can withstand the frequent impact and friction of high-speed looms and is not easy to rust or deform. It is one of the most commonly used reed materials. The reed stamping machine stamps the metal sheet into the shape of the reed through a mold. This method has high production efficiency and is suitable for large-scale production.

[0003] In some existing reed stamping machines, when stamping reeds, the operator manually places the raw material to be stamped on the lower die, manually adjusts the position for alignment, starts the equipment, and uses an external hydraulic pump to pressurize the hydraulic rod to drive the upper die downward to complete the stamping. After completion, the operator reaches into the equipment and uses their hands or tools to remove the formed reed from the lower die or material trough and put it into a collection container.

[0004] Existing reed stamping machines of this type have the following problems: when stamping reeds, manual feeding and contact with the stamping area pose a risk of accidental injury. To address this, we propose a reed stamping machine. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-5This embodiment provides a technical solution: a reed punching machine, including a machine housing 1, a mounting platform 2 at the upper end of the machine housing 1, guide rods 3 fixedly connected to the four corners of the upper end of the mounting platform 2, a sliding plate 4 slidably connected between the four guide rods 3, an upper die 7 at the middle of the lower end of the sliding plate 4, a lower die 8 at the middle of the upper end of the mounting platform 2, and an automatic feeding mechanism 9. A PLC controller 12 is provided at the right end of the machine housing 1, the input end of the PLC controller 12 is electrically connected to an external power supply, a top plate 5 is fixedly connected between the upper ends of the guide rods 3, a hydraulic rod 6 is provided at the upper end of the top plate 5, the telescopic end of the hydraulic rod 6 is fixedly connected to the middle of the upper end of the sliding plate 4 (the oil port of an external hydraulic pump is connected to the oil circuit of the hydraulic rod 6 through an oil pipe, the external hydraulic pump is a reed punching machine hydraulic pump commonly used in the prior art, and the output end of the PLC controller 12 is electrically connected to the input end of the external hydraulic pump), and safety light curtains 10 are evenly distributed at the left and right ends and the front and rear ends between the top plate 5 and the mounting platform 2. All light curtains 10 are bidirectionally electrically connected to the PLC controller 12. The middle part of the front and rear ends of the mounting platform 2 is respectively provided with a pouring pipe 11 corresponding to the material trough. When stamping the reed, the steel coil is first introduced between the upper die 7 and the lower die 8. Then, the hydraulic rod 6 is pressurized by an external hydraulic pump. The telescopic end of the hydraulic rod 6 pushes the sliding plate 4 to slide down along the guide rod 3. The sliding plate 4 drives the upper die 7 to slide down through the lower die 8 to complete the stamping of the reed. Then the formed reed falls into the inside of the material trough. The reed will be discharged along the pouring pipe 11. The safety light curtain 10 is installed at the left and right ends and the front and rear ends between the top plate 5 and the mounting platform 2 to form a protective barrier composed of infrared beams, covering the periphery of the stamping area. When the operator's body part or other foreign objects enter the stamping danger area, they will block the infrared beams. Once the safety light curtain 10 detects that the beam is blocked, it will immediately send a signal to the PLC controller 12 to trigger the emergency stop of the stamping machine, prevent the hydraulic rod 6 from pressing down, and avoid personnel being squeezed or injured by the stamping parts.

[0024] Automatic feeding mechanism 9: It includes a chute 91, an L-shaped slide bar 92, a pusher plate 93, a support bar 94, a rack 95, a rotating column 96, and a gear 97. The mounting platform 2 has a material trough inside. The left and right inner walls of the trough are respectively provided with chute 91. An L-shaped slide bar 92 is slidably connected between the chute 91. A pusher plate 93 is fixedly fitted in the middle of the L-shaped slide bar 92. A support bar 94 is provided on the lower left side of the L-shaped slide bar 92. A rack 95 is provided on the left end of the support bar 94. A rotating column 96 is rotatably connected to the bottom wall of the left end of the mounting platform 2. A gear 97 is fixedly connected to the upper end of the rotating column 96. The rack 95 and the gear... The automatic feeding mechanism 9 also includes a drive assembly 98, which comprises a gear 981, a rotating shaft 982, a circular frame 983, a half-gear ring 984, and a half-gear 985. The rotating shaft 982 is rotatably connected to the top wall of the housing 1. A circular frame 983 is fixedly fitted onto the upper outer wall of the rotating shaft 982. A half-gear ring 984 is provided on the inner wall of the circular frame 983. A half-gear 985 is fixedly connected to the middle of the circular frame 983. The lower end of the rotating column 96 is fixedly connected to the gear 981, the half-gear ring 984, and the half-gear 985. 85 is installed in conjunction with gear 981. The drive assembly 98 also includes a motor 986. A support plate is provided on the upper side inside the housing 1, and the motor 986 is located at the lower end of the support plate. The upper end of the output shaft of the motor 986 is fixedly connected to the lower end of the rotating shaft 982. The input end of the motor 986 is electrically connected to the output end of the PLC controller 12. Then, by controlling the PLC controller 12, the motor 986 operates. The output shaft of the motor 986 drives the rotating shaft 982 to rotate, and the rotating shaft 982 drives the circular frame 983 to rotate. The half-tooth ring 984 on the inner wall of the circular frame 983 and the half-tooth ring in the middle... Gear 985 intermittently meshes with gear 981 during rotation. When half-gear ring 984 meshes with gear 981, gear 981 drives rotating column 96 to rotate forward. When half-gear 985 meshes with gear 981, gear 981 drives rotating column 96 to rotate in reverse. In turn, rotating column 96 will rotate in both directions, which will drive gear 97 to rotate in both directions. Gear 97 drives L-shaped slide bar 92 to slide left and right along slide groove 91 through meshing rack 95 and support bar 94. Push plate 93 then reciprocates in the groove, pushing the stamped reed out of the groove.

[0025] The working principle of the reed stamping machine provided by this utility model is as follows: When stamping the reed, the steel coil is first introduced between the upper die 7 and the lower die 8. Then, the hydraulic rod 6 is pressurized by an external hydraulic pump. The telescopic end of the hydraulic rod 6 pushes the sliding plate 4 to slide downward along the guide rod 3. The sliding plate 4 drives the upper die 7 downward through the lower die 8 to complete the reed stamping. Then, the formed reed falls into the inside of the material groove. Then, the motor 986 is operated by the control of the PLC controller 12. The output shaft of the motor 986 drives the rotating shaft 982 to rotate. The rotating shaft 982 drives the circular frame 983 to rotate. The half-tooth ring 984 on the inner wall of the circular frame 983 and the half-gear 985 in the middle intermittently mesh with the second gear 981 during the rotation. When the half-tooth ring 984 meshes with the second gear 981, the second gear 981 drives the rotating column 96 to rotate forward. When the half-gear 985 meshes with the second gear 981, Gear 2 981 drives the rotating column 96 to reverse, and then the rotating column 96 will rotate in both directions. The rotating column 96 will drive gear 1 97 to rotate in both directions. Gear 1 97 drives the L-shaped slide bar 92 to slide left and right along the slide groove 91 through the meshing rack 95 and support bar 94. The pusher plate 93 then moves back and forth in the material groove, pushing the stamped reed out of the material groove. The reed will be discharged along the discharge pipe 11. The safety light curtain 10 is installed at the left and right ends and the front and rear ends between the top plate 5 and the mounting platform 2, forming a protective barrier composed of infrared beams, covering the periphery of the stamping area. When the operator's body parts or other foreign objects enter the stamping danger area, they will block the infrared beams. Once the safety light curtain 10 detects that the beam is blocked, it will immediately send a signal to the PLC controller 12 to trigger the emergency stop of the stamping machine. The PLC controller 12 controls the external hydraulic pump to stop running, preventing the hydraulic rod 6 from pressing down, and avoiding personnel being squeezed or injured by the stamping parts.

[0026] It is worth noting that in the above embodiments, the motor 986 and the safety light curtain 10 can be selected from KS-370 and YKB20 respectively. The PLC controller 12 is equipped with a switch button that corresponds one-to-one with the motor 986 and the safety light curtain 10 and is used to control their switching operation.
