Description

Technical Field

[0001] This utility model belongs to the technical field of textile machinery and equipment, and specifically relates to a warp beam lifting device for a loom. Background Technology

[0002] In the textile production process, the warp beam lifting device of the loom is an indispensable key piece of equipment. Its main function is to assist in the lifting, handling, flipping and installation of the warp beam. With the help of mechanical transmission, hydraulic drive or electric control, the device can smoothly transfer the heavy warp beam from the ground or transport frame to the designated position on the loom, ensuring that the warp beam is installed accurately and stably, effectively reducing the labor intensity of operators, significantly improving installation efficiency and accuracy, and preventing damage to the warp beam and equipment during handling, thus ensuring production safety. Therefore, this type of device is widely used in the supporting systems of various textile equipment such as air-jet looms and water-jet looms. However, existing warp beam lifting devices for looms have obvious limitations. Although they can achieve basic warp beam lifting and handling functions, in actual production scenarios, most devices can only be adapted to warp beams of specific specifications. When faced with warp beams of different diameters and lengths, operators often need to frequently replace equipment parts or even the entire device. This not only greatly increases the complexity of operation and prolongs equipment debugging time, but also leads to a significant reduction in production efficiency, making it difficult to meet the current textile industry's demand for multi-variety, small-batch, and flexible production. To address the aforementioned problems, this application proposes a warp beam lifting device for a loom. Utility Model Content

[0003] To address the aforementioned problems in the existing technology, this utility model provides a warp beam lifting device for a loom, which is capable of operating on warp beams of different sizes.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a warp beam lifting device for a weaving machine, comprising a base plate, a controller disposed above the base plate, a slotted frame fixedly connected to the upper surface of the base plate, two threaded rods rotatably connected to the inner wall of the slotted frame, two sliding blocks slidably connected inside the slotted frame, the inner wall of each sliding block being threadedly connected to the outer surface of the threaded rod, a brake motor disposed on both the front and back of the slotted frame, the ends of the two threaded rods that are far apart from each other being fixedly connected to the output end of the brake motor, and two connecting frames disposed above the slotted frame; Each of the connecting frames has a sliding frame slidably connected inside. Each of the sliding blocks has two first electric push rods fixedly connected to its upper surface. The telescopic ends of each set of first electric push rods are fixedly connected to the front and back of each sliding frame, respectively. Each of the sliding frames has a support frame fixedly connected to its left side. Each of the support frames has a limit frame slidably connected inside. Each of the support frames has a second electric push rod fixedly connected to its inner wall. The telescopic ends of each second electric push rod are fixedly connected to the right side of the limit frame. A counterweight is provided above the base plate, and an assist rod is provided above the counterweight.

[0005] As a preferred embodiment of this utility model, the bottom surface of the base plate is fixedly connected to two sets of wheel frames, and each wheel frame has a rotating wheel rotatably connected to its inner wall.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By using a cooperative structure comprising a threaded rod, a brake motor, and sliding blocks, the brake motor drives the threaded rod to rotate, which in turn moves the two sliding blocks relative to or towards each other within the slot frame. This adjusts the horizontal distance between the connecting frames on both sides and the clamping assembly, adapting to the operational needs of warp beams of different lengths. Furthermore, the extension and retraction of the first electric push rod causes the sliding frame to rise and fall within the connecting frame, flexibly adjusting the clamping height to meet the lifting requirements of different warp beam positions. Simultaneously, the second electric push rod pushes the limiting frame to slide within the support frame, changing the extension length of the limiting frame to accommodate warp beams of different diameters. The device features a clamping and fixing mechanism. Furthermore, an assist rod fixed to the base plate provides a stable gripping point for the operator, facilitating the movement of the device. A counterweight mounted on the base plate balances the device's center of gravity based on the weight of the warp beam, preventing tipping during lifting. These multi-dimensional adjustment structures and auxiliary components work together to achieve stable lifting and handling of warp beams of various specifications without requiring replacement of parts. This effectively solves the problem of limited adaptability in existing devices, significantly improving equipment versatility and ease of operation, reducing time costs associated with replacing parts, increasing warp beam installation efficiency, and better meeting the diverse production needs of the textile industry.

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.

[0015] Example Please see Figure 1-6 The present invention provides the following technical solution: a warp beam lifting device for a weaving machine, including a base plate 1, a controller 14 above the base plate 1, a slot frame 2 fixedly connected to the upper surface of the base plate 1, two threaded rods 3 rotatably connected to the inner wall of the slot frame 2, two sliding blocks 10 slidably connected inside the slot frame 2, the inner wall of each sliding block 10 being threadedly connected to the outer surface of the threaded rod 3, a brake motor 9 being provided on both the front and back of the slot frame 2, the ends of the two threaded rods 3 that are far apart from each other being fixedly connected to the output end of the brake motor 9, and two connecting frames 19 being provided above the slot frame 2; Each connecting frame 19 has a sliding frame 18 slidably connected inside. Each sliding block 10 has two first electric push rods 17 fixedly connected to its upper surface. The telescopic ends of each set of first electric push rods 17 are fixedly connected to the front and back of each sliding frame 18, respectively. Each sliding frame 18 has a support frame 22 fixedly connected to its left side. Each support frame 22 has a limit frame 20 slidably connected inside. Each support frame 22 has a second electric push rod 21 fixedly connected to its inner wall. The telescopic ends of each second electric push rod 21 are fixedly connected to the right side of the limit frame 20. A counterweight 13 is provided above the base plate 1. An assist rod 11 is provided above the counterweight 13. In this embodiment, the controller 14 is a PLC programmable logic controller, which has high-precision control and multi-device linkage functions, and can realize precise control of each component. At the same time, the brake motor 9 is a power-off braking type servo motor. This motor can not only ensure stable and efficient power output, but also stop rotation immediately through the built-in brake device at the moment of power failure, effectively preventing the warp beam from slipping accidentally and ensuring operational safety. The first electric push rod 17 and the second electric push rod 21 are both high-load electric cylinders, which have the characteristics of large thrust, high stroke accuracy and fast response speed. They can quickly and stably realize the lifting and lowering of the sliding frame 18 and the extension and retraction of the limit frame 20 to meet the precise clamping requirements of warp beams of different specifications.

[0016] Specifically, two sets of wheel frames 4 are fixedly connected to the bottom surface of the base plate 1. Each wheel frame 4 has a rotating wheel 5 rotatably connected to its inner wall. In this embodiment, the cooperation between the rotating wheel 5 and the wheel frame 4 enables the device to have flexible mobility. Operators can easily move the device to different looms or warp beam storage locations, effectively improving the flexibility and efficiency of equipment use and reducing the labor cost of handling the device.

[0017] Specifically, each brake motor 9 has a fixed base 6 fixedly connected to its bottom surface. The two fixed bases 6 are fixedly connected to the front and back sides of the base plate 1 respectively on their side faces. In this embodiment, the brake motor 9 is securely fixed to the base plate 1 by the stable installation of the fixed base 6, which ensures that the motor remains stable when driving the threaded rod 3 to rotate, avoids the impact of motor shaking on transmission accuracy and device operation safety, and provides a reliable support foundation for the brake motor 9.

[0018] Specifically, a protective shell 7 is fixedly connected to the outer surface of each fixed base 6. Each protective shell 7 is fitted onto the outside of the brake motor 9. In this embodiment, the protective design of the protective shell 7 can effectively block dust, lint, moisture and other impurities in the production environment from entering the brake motor 9, preventing the motor from short-circuiting, wearing and other faults caused by foreign objects, extending the service life of the motor, reducing the frequency and cost of equipment maintenance, and ensuring the long-term stable operation of the device.

[0019] Specifically, two connecting rods 8 are fixedly connected to the bottom surface of the assist rod 11. The bottom end of each connecting rod 8 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the rigid connection structure between the connecting rod 8 and the assist rod 11 provides a stable gripping point for the operator when the device moves. When pushing the device, the operator can grip the assist rod 11 to apply force, and the connecting rod 8 will evenly transmit the thrust to the base plate 1, avoiding device tilting caused by single-point force. At the same time, the ergonomic design is optimized, making the pushing action more in line with human biomechanics, reducing operator fatigue, and improving the convenience and controllability of device movement.

[0020] Specifically, a fixing plate 12 is fixedly connected to the bottom surface of the counterweight 13. The bottom surface of the fixing plate 12 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the counterweight 13 is stably installed on the base plate 1 through the transition connection structure of the fixing plate 12. The fixing plate 12 increases the contact area between the counterweight 13 and the base plate 1, so that the weight load of the counterweight 13 is evenly distributed to the base plate 1, avoiding deformation of the base plate 1 due to excessive local stress. At the same time, the rigid connection of the fixing plate 12 can prevent the counterweight 13 from shifting or shaking during the movement or operation of the device, ensuring that it can always effectively balance the eccentric torque during shaft lifting, further improving the overall stability and operational safety of the device.

[0021] Specifically, a mounting plate 15 is fixedly connected to the left side of the controller 14. The bottom surface of the mounting plate 15 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the controller 14 is securely installed on the base plate 1 by the fixed support of the mounting plate 15, so that the controller 14 and other components of the device remain relatively fixed, which facilitates the connection of the circuit and operation control. At the same time, it avoids the controller 14 from being displaced due to vibration during the operation of the device, which would affect its control accuracy and stability.

[0022] Specifically, a reinforcing plate 16 is fixedly connected to the bottom surface of each connecting frame 19, and the bottom surface of each reinforcing plate 16 is fixedly connected to the upper surface of the sliding block 10. In this embodiment, the connection strength between the connecting frame 19 and the sliding block 10 is enhanced by the structural reinforcement of the reinforcing plate 16. When the first electric push rod 17 drives the sliding frame 18 to rise or fall, or when the device clamps or transports the shaft, the reinforcing plate 16 can disperse the stress and prevent the connection part from deforming or breaking due to excessive force, thereby improving the reliability and durability of the overall structure of the device.

[0023] The working principle and usage process of this utility model are as follows: In use, the operator first uses the moving mechanism formed by rotating wheel 5 and wheel frame 4 to flexibly push the device to the warp beam storage position. During this process, the operator can hold the assist rod 11 and use the connecting rod 8 for leverage. Based on the actual terrain and the warp beam placement position, the device's orientation can be precisely adjusted through steering and translation. Then, the length and diameter parameters of the warp beam to be lifted are observed, and the corresponding values ​​are input into the control interface of controller 14. Controller 14 immediately sends a start command to the brake motor 9. The brake motor 9 operates, driving the threaded rod 3 to begin rotating. Based on the threaded transmission principle, the two sliding blocks 10 in the groove... The inner threaded rod 3 slides relative to or towards each other within the frame 2, causing the upper connecting frame 19 to move horizontally until the distance between the two support frames 22 matches the length of the warp beam. Simultaneously, the controller 14 controls the first electric push rod 17 to extend and retract. The extension end of the first electric push rod 17 pushes and pulls the sliding frame 18, causing it to slide up and down within the connecting frame 19, quickly adjusting the support frame 22 to a suitable clamping height. Finally, under the control of the controller 14, the second electric push rod 21 pushes the limiting frame 20 to slide within the support frame 22, causing the limiting frame 20 to conform to the side of the warp beam, completing precise limiting of the warp beam diameter direction, and realizing the clamping mechanism's length, height, and... The width is adaptively adjusted in three dimensions. After adjustment, the operator operates the controller 14 again to issue a lifting command. The first electric push rod 17 slowly extends, driving the support frame 22 to lift the warp beam upwards. The brake motor 9 continues to operate stably to ensure the threaded rod 3 is fixed in position and maintain the horizontal stability of the clamping mechanism. Once the warp beam is lifted to the predetermined height, the operator pushes the device to the side of the loom. The controller 14 precisely controls the retraction of the first electric push rod 17, allowing the warp beam to smoothly descend to the installation position on the loom. After the warp beam is installed in place, the controller 14 controls the brake motor 9 to de-energize, and the built-in brake device of the brake motor 9 is activated instantly. The device moves and locks the threaded rod 3 to prevent accidental rotation. At the same time, the second electric push rod 21 retracts, driving the limit frame 20 to retract and release the clamp on the warp beam. Thus, the device completes one work cycle and returns to its initial state, ready for the next warp beam lifting task. Throughout the process, the protective shell 7 isolates dust, moisture and other impurities to prevent damage to the brake motor 9. Meanwhile, the counterweight block 13, together with the fixing plate 12, dynamically balances the center of gravity of the device according to the weight of the warp beam to prevent tipping. The reinforcing plate 16 strengthens the connection strength between the connecting frame 19 and the sliding block 10, ensuring stable operation of the device under heavy load, and comprehensively guaranteeing the safety and efficiency of the operation.

[0024] 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.
