Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology, specifically relating to a shearing mechanism for a rapier loom. Background Technology

[0002] The rapier loom is a shuttleless loom that uses a rapier shuttle as the weft insertion carrier. It is an important type of weaving equipment. With its unique weft insertion method, it is widely used in the production of fabrics made of various fiber materials such as cotton, wool, silk, linen, and chemical fibers. It is particularly outstanding in the weaving of wide, thick, or high-value-added fabrics, such as industrial fabrics, high-end decorative fabrics, and special industrial fabrics.

[0003] However, during the operation of a rapier loom, a shearing device is needed to cut the fabric or yarn. Currently, the mainstream shearing method relies on the squeezing action of the blade to complete the cut. However, this method has obvious limitations. On the one hand, the blade is prone to uneven force during squeezing, resulting in uneven cuts and affecting the smoothness of the fabric edges. On the other hand, for thicker or tougher yarns, incomplete cutting may occur, leaving yarn residues and strands, which in turn affects the stability of subsequent weaving processes and the final product quality.

[0004] To address the aforementioned problems, this application proposes a shearing mechanism for a rapier loom. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a shearing mechanism for a rapier loom, which features more precise and thorough shearing, smooth and even cuts, and strong adaptability to different types of yarn.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shearing mechanism for a shuttle loom, comprising a base frame, wherein two limiting frames and two sets of first electric push rods are respectively arranged inside the base frame, and the sides of the two limiting frames that are far apart from each other are fixedly connected to the telescopic ends of each set of first electric push rods. A slot frame is fixedly connected to the upper surface of the base frame, and a controller is arranged on the front of the slot frame. A sliding frame is slidably connected inside the slot frame, and a threaded rod is rotatably connected to the inner wall of the slot frame. A first rotary motor is arranged on the right side of the slot frame, and the power output end of the first rotary motor is fixedly connected to the right end of the threaded rod. The inner wall of the sliding frame is threadedly connected to the outer surface of the threaded rod. A second electric push rod is arranged inside the sliding frame, and a rotating frame is arranged below the second electric push rod. A rotating blade holder is rotatably connected to the inner wall of the rotating frame, and a second rotary motor is arranged on the front of the rotating frame. The power output end of the second rotary motor is fixedly connected to the transmission end of the rotating blade holder.

[0007] As a preferred embodiment of this utility model, the bottom surface of the base frame is fixedly connected to two support seats, and each support seat is provided with two fixing pins inside.

[0008] As a preferred technical solution of this utility model, each group of first electric push rods has a support plate fixedly connected to one end of each group that is far apart from each other, and the side of each group of support plates that is far apart from each other is fixedly connected to the inner wall of the base frame.

[0009] As a preferred embodiment of this utility model, the inner bottom wall of the base frame is fixedly connected to two limiting plates, and the outer surface of each limiting plate is in contact with the inner wall of the limiting frame.

[0010] As a preferred embodiment of this utility model, a connecting seat is fixedly connected to the bottom surface of the first rotary motor, and the left side of the connecting seat is fixedly connected to the right side of the slot frame.

[0011] As a preferred embodiment of this utility model, a mounting plate is fixedly connected to the back of the controller, and the back of the mounting plate is fixedly connected to the front of the slot frame.

[0012] As a preferred embodiment of this utility model, a fixing ring is fixedly connected to the outer surface of the second electric push rod, and the upper surface of the fixing ring is fixedly connected to the bottom surface of the sliding frame.

[0013] As a preferred embodiment of this utility model, a fixing frame is fixedly connected to the upper surface of the second rotary motor, and the back of the fixing frame is fixedly connected to the front of the rotating frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting two limiting frames and a first electric push rod, the extension and retraction of the first electric push rod can drive the limiting frames to stably clamp and position fabrics of different widths, avoiding fabric deviation during cutting and ensuring accurate cutting position. At the same time, with the help of the first rotary motor, threaded rod and sliding frame, the sliding frame can be driven to move laterally along the slot frame to perform full cutting of the clamped fabric. The second electric push rod drives the rotating frame and rotating blade holder to move up and down, realizing the adjustment of cutting height to adapt to fabrics or yarns of different thicknesses. The second rotary motor and rotating blade holder work together to replace the traditional blade extrusion cutting with rotary cutting. The high-speed rotation of the rotating blade holder forms continuous cutting force. Combined with stable clamping and positioning, the cut is smoother and flatter, effectively solving the problems of uneven cuts and incomplete cutting that are easy to occur in traditional extrusion cutting. It also improves the cutting ability of coarse, hard or high-toughness yarns, ensuring the stability of subsequent weaving processes and product quality. Attached Figure Description

[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] Example

[0024] Please see Figure 1-5This utility model provides the following technical solution: a shearing mechanism for a shuttle loom, including a base frame 1. Two limiting frames 2 and two sets of first electric push rods 5 are respectively arranged inside the base frame 1. The sides of the two limiting frames 2 that are far apart from each other are fixedly connected to the telescopic ends of each set of first electric push rods 5. A slotted frame 13 is fixedly connected to the upper surface of the base frame 1. A controller 10 is arranged on the front of the slotted frame 13. A sliding frame 14 is slidably connected inside the slotted frame 13. A threaded rod 12 is rotatably connected to the inner wall of the slotted frame 13. The right side of the slotted frame 13... A first rotary motor 8 is provided, the power output end of the first rotary motor 8 is fixedly connected to the right end of the threaded rod 12, the inner wall of the sliding frame 14 is threadedly connected to the outer surface of the threaded rod 12, a second electric push rod 15 is provided inside the sliding frame 14, a rotating frame 17 is provided below the second electric push rod 15, a rotating tool holder 20 is rotatably connected to the inner wall of the rotating frame 17, a second rotary motor 19 is provided on the front of the rotating frame 17, and the power output end of the second rotary motor 19 is fixedly connected to the transmission end of the rotating tool holder 20.

[0025] In this embodiment, the controller 10 adopts a programmable logic controller (PLC), which is a digital computing and operating electronic system designed specifically for industrial environments. It has a programmable memory inside, which can store instructions for performing logical operations, sequential control, timing, counting and arithmetic operations, and can achieve precise control of various machines or production processes through digital or analog input / output interfaces. In actual operation, the PLC can coordinate the control of the actions of various components, and at the same time, the opening design of the limit frame 2 enables the rotating blade holder 20 to be precisely aligned and complete the cutting operation on the clamped and fixed fabric.

[0026] Specifically, the bottom surface of the base frame 1 is fixedly connected to two support seats 3, and each support seat 3 is provided with two fixing pins 4 inside. In this embodiment, the base frame 1 can be stably installed at the designated position of the loom through the cooperation of the support seats 3 and the fixing pins 4, which not only ensures the overall installation stability of the shearing mechanism, but also facilitates the later position adjustment or maintenance of the equipment through the detachable design of the fixing pins 4, and avoids the shearing accuracy being affected by the shaking of the equipment during the shearing process.

[0027] Specifically, each set of first electric push rods 5 has a support plate 7 fixedly connected to the opposite end of each other, and the opposite side of each set of support plates 7 is fixedly connected to the inner wall of the base frame 1. In this embodiment, the first electric push rods 5 are connected and fixed to the base frame 1 by the support plates 7, which increases the installation contact area of ​​the first electric push rods 5 and disperses the reaction force generated when they work. This avoids loosening or deformation of the connection parts due to force concentration after long-term use, and ensures that the first electric push rods 5 can stably drive the limit frame 2 to complete the clamping action.

[0028] Specifically, two limiting plates 6 are fixedly connected to the inner bottom wall of the base frame 1. The outer surface of each limiting plate 6 is in contact with the inner wall of the limiting frame 2. In this embodiment, the limiting plates 6 form a precise guide for the movement direction of the limiting frame 2, ensuring that the two limiting frames 2 always remain parallel and aligned when clamping the fabric, making the fabric more stable during the shearing process.

[0029] Specifically, a connecting seat 9 is fixedly connected to the bottom surface of the first rotary motor 8. The left side of the connecting seat 9 is fixedly connected to the right side of the slot frame 13. In this embodiment, the first rotary motor 8 and the slot frame 13 are stably connected by the connecting seat 9, which increases the connection area and improves the stability of the motor when it is working, avoids vibration or displacement during high-speed operation, ensures that the threaded rod 12 can be smoothly transmitted, and ensures the moving accuracy of the sliding frame 14.

[0030] Specifically, a mounting plate 11 is fixedly connected to the back of the controller 10. The back of the mounting plate 11 is fixedly connected to the front of the slot frame 13. In this embodiment, the mounting plate 11 provides a stable mounting carrier for the controller 10, which not only puts the controller 10 in a position that is easy to operate and observe, but also reduces the impact of loom vibration on the internal components of the controller 10 through the buffering effect of the mounting plate 11. At the same time, it is convenient to disassemble, maintain or debug the controller 10 as needed in the future.

[0031] Specifically, a fixing ring 16 is fixedly connected to the outer surface of the second electric push rod 15. The upper surface of the fixing ring 16 is fixedly connected to the bottom surface of the sliding frame 14. In this embodiment, the fixing ring 16 enhances the connection strength between the second electric push rod 15 and the sliding frame 14, preventing the second electric push rod 15 from shaking or shifting due to uneven force when it drives the rotating frame 17 and the rotating blade holder 20 to move up and down, ensuring the accuracy of the shearing height adjustment, and extending the service life of the second electric push rod 15.

[0032] Specifically, a fixing frame 18 is fixedly connected to the upper surface of the second rotary motor 19. The back of the fixing frame 18 is fixedly connected to the front of the rotating frame 17. In this embodiment, the second rotary motor 19 is firmly fixed to the rotating frame 17 by the fixing frame 18, which can effectively counteract the torque force generated when the motor rotates at high speed, prevent the connection between the motor and the rotating frame 17 from loosening, ensure that the rotary blade holder 20 can stably output shearing force, and ensure the continuity and reliability of the shearing action.

[0033] The working principle and usage process of this utility model are as follows: In use, the entire shearing mechanism is first securely installed at the corresponding position on the rapier loom using the support base 3 and fixed pin 4 on the bottom surface of the base frame 1, ensuring that the equipment matches the weaving rhythm of the loom. Next, the fabric is passed between the two limiting frames 2, placing the part to be sheared within the clamping range of the limiting frames 2, preparing for subsequent shearing. After starting the equipment, the controller 10 enters the working state, receiving the weft insertion completion signal from the loom in real time. When the rapier shuttle introduces the weft yarn into the fabric and it is in place, the controller 10 issues a command to activate the two sets of first electric push rods 5. During shearing, the telescopic end of the first electric push rod 5 drives the two limiting frames 2 to move towards the center. Under the guidance of the limiting plate 6, the limiting frames 2 remain parallel and aligned, stably clamping the part of the fabric to be sheared. The second electric push rod 15 starts, pushing the rotating frame 17 and the rotating blade holder 20 downward until the rotating blade holder 20 contacts the part of the fabric to be sheared. At the same time, the second rotary motor 19 starts to run at high speed, driving the rotating blade holder 20 to rotate rapidly. The continuous shearing force generated by the rotation cuts the fabric. During the shearing process, the limiting frames 2 continuously clamp the fabric to prevent it from shifting, ensuring... With precise cutting position, the controller 10 starts the first rotary motor 8 based on the fabric thickness and cutting position parameters. The first rotary motor 8 drives the threaded rod 12 to rotate, causing the sliding frame 14 to move laterally along the slot frame 13, which in turn drives the rotary cutter 20 to slide and cut along the opening of the limiting frame 2. After cutting is completed, the second rotary motor 19 stops operating, the second electric push rod 15 drives the rotary cutter 20 to reset upwards, the first rotary motor 8 rotates in the opposite direction, causing the sliding frame 14 to return to its initial position, the first electric push rod 5 retracts, the limiting frame 2 releases the fabric, and the fabric enters the next process with the loom's conveyor mechanism. During this process, the controller 10 achieves precise matching between the shearing action and the weaving rhythm of the loom through the linkage control of various components, ensuring continuous and efficient production. If it is necessary to change the fabric type or adjust the shearing parameters, the controller 10 can reset parameters such as the clamping force of the first electric push rod 5, the travel of the first rotary motor 8, the lifting height of the second electric push rod 15, and the speed of the second rotary motor 19 to adapt to the shearing requirements of different fabrics. During later maintenance, the fixed pin 4, mounting plate 11, and other components can be disassembled to inspect or replace the vulnerable parts, ensuring long-term stable operation of the equipment.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
