Description

TECHNICAL FIELD

[0001] The utility model relates to metal wire screen braider technical field, specifically, relate to a metal wire screen braider side pull opening device. BACKGROUND

[0002] In the development history of metal wire screen weaving industry, metal wire screen braider is always the core production equipment, and its performance is closely related to the quality of the woven metal wire screen. With the continuous expansion of the application demand of metal wire screen in various industries, higher and higher requirements are put forward for the quality, specifications and production efficiency of metal wire screen.

[0003] The traditional metal wire screen braider faces many problems to be solved in actual weaving operation. In terms of its side pull opening related link, this link plays a key role in realizing the precise interweaving of warp and weft metal wires, ensuring the uniformity of metal wire screen mesh and the overall weaving quality. However, the early braider is relatively simple and extensive in structure design and function realization, and often cannot well cope with complex weaving conditions.

[0004] For example, in the control of the motion of the heald frame, the heald frame is an important part involved in the interweaving of warp and weft wires, and the stability and precision of its up and down sliding have a great influence on the weaving result. However, the traditional braider does not comprehensively consider the influence of the gravity of the heald frame when driving the heald frame to move, so that the heald frame is prone to have the phenomenon of unsmooth movement, jamming and other phenomena due to gravity factors in the process of frequent up and down sliding, which further leads to the fact that the warp metal wires cannot be lifted and lowered according to the ideal state, and finally affects the weaving quality of the metal wire screen, resulting in uneven mesh size, inconsistent weaving density and other quality problems.

[0005] In addition, with the diversification demand of market for metal wire screen product specifications, different weaving projects may require weaving metal wire screens of different widths, different densities and using different thickness metal wires. Due to the lack of sufficient flexibility and adaptability, the traditional braider is difficult to quickly and effectively adjust when facing these changes, and often needs to consume a lot of manpower and material resources to reform the equipment or replace the related parts, which not only greatly slows down the production progress, but also increases the production cost, seriously restricts the efficient development of enterprises in metal wire screen weaving business and the response ability to market diversification demand.

[0006] In addition, in the long-term production practice, the traditional braider also has deficiencies in running stability. Due to the continuous influence of gravity and other factors, the cooperation between the parts in the braider is prone to deviation, which aggravates the wear of the parts and further affects the service life and overall performance of the equipment. Frequent repair and maintenance have become a big trouble in the production process of enterprises.

[0007] In summary, the traditional wire mesh braider has been difficult to meet the growing demand for high quality, high efficiency, diversified production of the wire mesh weaving industry in many aspects related to side pulling opening, and it is urgent to improve and optimize it, and to develop more advantageous related devices to improve the level of the entire wire mesh weaving production.

[0044] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0045] As Figs. 1-2 The utility model provides a wire mesh braider side pull opening device, including frame body 1, the heald frame 2 is arranged on the frame body 1 and slides up and down, and the heald frame 2 is provided with at least two in parallel, the driving arm 3 swing is arranged on the frame body 1, the driving arm 3 has output end 31, and the output end 31 is hinged (can pass through connecting rod, and the both ends of the connecting rod are hinged with the output end 31 and the heald frame 2 respectively) with the heald frame 2, and the driving arm 3 is used to drive the heald frame 2 to slide up and down, the gravity balance assembly 4 is arranged on the frame body 1, and the gravity balance assembly 4 is connected with the heald frame 2, and the gravity balance assembly 4 is used to balance the gravity of the heald frame 2.

[0046] In the embodiment, the basic framework of the wire mesh braider side pull opening device is constructed by the setting of the frame body 1, the heald frame 2, the driving arm 3 and the gravity balance assembly 4. The frame body 1 serves as the supporting basis of the whole device and provides mounting positions for various components. The heald frame 2 is arranged to slide up and down and has at least two in parallel, which provides a movable component basis for subsequent implementation of corresponding operations (such as control of wire, etc.) in the weaving process. The driving arm 3 is swingingly arranged and hinged with the heald frame 2, which can provide power for the up-and-down sliding of the heald frame 2 and make it perform corresponding actions according to the weaving process requirements. The gravity balance assembly 4 is connected with the heald frame 2, which can effectively solve the influence of the self-gravity of the heald frame 2, ensure that the heald frame 2 is more stable and smooth during the up-and-down sliding process, and help to accurately control the movement position, so as to ensure that the related operations of the wire mesh braider side pull opening can be stably and accurately performed.

[0047] In particular, the gravity balance assembly 4 is crucial for the smooth operation of the entire device. During the up-and-down sliding of the heald frame 2, if only the driving of the driving arm 3 is relied on without considering the influence of its own gravity, problems such as unsmooth movement, jamming, and even inability to accurately control the position may occur. The gravity balance assembly 4 can effectively reduce the load of the driving arm 3 in overcoming gravity by applying a force in the opposite direction of the gravity of the heald frame 2, so that the heald frame 2 can slide up and down more lightly and smoothly under the driving of the driving arm 3, improving the accuracy and stability of the movement, and thus ensuring that the side-lift opening operation of the braiding machine can be accurately performed according to the preset process requirements, and ensuring that the quality of the braided wire mesh meets the standards.

[0048] As an embodiment, the gravity balance assembly 4 includes a spring 41, one end of which acts on the heald frame 2 and the other end of which acts on the frame body 1, and the spring 41 provides a pulling force or a supporting force to offset the gravity of the heald frame 2.

[0049] In this embodiment, the spring 41 is used as the key component for gravity balance, one end of which acts on the heald frame 2 and the other end of which acts on the frame body 1, and the pulling force or the supporting force provided by the spring 41 is used to offset the gravity of the heald frame 2. This way has a relatively simple structure and low cost, and through the elastic deformation characteristics of the spring 41, the spring force can be adjusted adaptively according to the position change of the heald frame 2, so as to maintain the gravity balance of the heald frame 2 to a certain extent, reduce the jamming or instability of the heald frame 2 movement caused by gravity, and help to improve the overall stability of the side-lift opening device of the braiding machine during operation, and ensure the normal development of the braiding work.

[0050] Further, the gravity balance assembly 4 further includes an adjusting screw 42, which is threadedly connected to the frame body 1, and one end of the spring 41 acting on the frame body 1 is connected to the adjusting screw 42, and the adjusting screw 42 is used to adjust the spring force of the spring 41 acting on the heald frame 2.

[0051] In this embodiment, the adjusting screw 42 is added to the gravity balance assembly and cooperates with the spring, and is threadedly connected to the frame body, so that one end of the spring 41 acting on the frame body is connected thereto. In this way, the operator can rotate the adjusting screw 42 to change its position on the frame body, and thus accurately adjust the spring force of the spring 41 acting on the heald frame 2. In actual application, the spring force can be flexibly adjusted according to different specifications of the heald frame 2, different braiding process requirements, etc., to achieve the best gravity balance effect, further optimize the up-and-down sliding action of the heald frame, and improve the adaptability and accuracy of the entire device to the side-lift opening operation in the braiding process.

[0052] As another implementation, the gravity balance assembly 4 comprises a counterweight 401, which is arranged to slide up and down; a guide wheel 402 is arranged to rotate on the frame 1; a rope 403 is connected to the heald frame 2 at one end and connected to the counterweight 401 after being guided by the guide wheel 402, and the counterweight 401 is used to balance the gravity of the heald frame 2.

[0053] In this embodiment, the gravity balance assembly is composed of the counterweight 401, the guide wheel 402, and the rope 403. The counterweight 401 is arranged to slide up and down, one end of the rope 403 is connected to the heald frame 2, and the other end is connected to the counterweight 401 after being guided by the guide wheel 402. The gravity of the counterweight 401 balances the gravity of the heald frame 2. This method is based on the principle of counterweight, which is relatively intuitive and stable. As long as the gravity of the counterweight 401 is set reasonably, the gravity of the heald frame can be effectively overcome, so that the heald frame 2 can slide up and down more easily and stably under the drive of the drive arm 3, reducing the influence of spring fatigue and other factors on the spring force, ensuring the long-term stable operation of the side-pulling opening device, and especially suitable for weaving scenes with high requirements for gravity balance stability.

[0054] Further, the gravity of the counterweight 401 is adjustable.

[0055] In this embodiment, the gravity of the counterweight 401 is adjustable, which greatly enhances the adaptability of the gravity balance assembly. When facing different models, different weights of the heald frame 2, or changes in weaving process that require adjustment of the heald frame 2 motion state, the gravity of the counterweight 401 can be easily changed to ensure that it can always be in good balance with the gravity of the heald frame. Without the need for large-scale modification of other structures of the entire device, the versatility and adjustability of the device are improved, and the cost and maintenance difficulty caused by product differentiation are reduced.

[0056] Further, the counterweight 401 has a cavity 404 inside, which is used to place substances to adjust the gravity of the counterweight 401.

[0057] In this embodiment, the cavity 404 is provided in the counterweight 401 for placing substances to adjust the gravity, providing a convenient and intuitive counterweight adjustment method. The operator can add or remove corresponding substances (such as iron blocks, sandstones, etc.) from the cavity according to actual needs, accurately adjust the weight of the counterweight, and achieve fine control of the gravity balance of the heald frame 2, further optimizing the operation performance of the device, meeting the requirements of various weaving processes, and the adjustment method is low in cost, easy to operate and implement.

[0058] Further, the counterweight 401 has a hanging ring 405 at the bottom.

[0059] In this embodiment, a hanging ring 405 is arranged at the bottom of the counterweight 401, expanding the way to adjust the gravity of the counterweight 401. The total gravity of the counterweight 401 can be increased by hanging additional weights (such as weights, etc.) on the hanging ring 405, which is complementary to the way of adding substances into the cavity 404, making the counterweight adjustment more flexible and diverse, and being able to more accurately match the heald frame gravity, adapt to more complex and variable weaving conditions, and improve the applicability of the entire device in different use scenarios.

[0060] Further, the heald frame 2 has a left frame 21 and a right frame 22, and the drive arm 3 has a plurality, and the left frame 21 and the right frame 22 are respectively hinged with the output ends 31 of two of the drive arms 3.

[0061] In this embodiment, the heald frame 2 is divided into a left frame 21 and a right frame 22, and the drive arm 3 has a plurality, and the left frame 21 and the right frame 22 are respectively hinged with the output ends of two of the drive arms 3. Such a setting makes both sides of the heald frame 2 be independently and accurately powered, ensuring that both sides of the heald frame 2 are more evenly stressed and move more smoothly and coordinately during the up and down sliding process, avoiding problems such as tilting and jamming caused by uneven unilateral stress, and helping to improve the accuracy and stability of the side opening operation of the weaving machine. Especially for wider metal mesh weaving, it can better ensure the weaving quality.

[0062] Further, the left frame 21 and the right frame 22 are both connected with the gravity balance assembly 4.

[0063] In this embodiment, the left frame 21 and the right frame 22 are both connected with the gravity balance assembly 4, further strengthening the gravity balance effect of the heald frame as a whole. No matter which side of the heald frame 2, its own gravity can be effectively counteracted, ensuring that both sides can move stably and lightly when the drive arm 3 drives the heald frame 2 to slide up and down, minimizing the adverse effects of gravity on the side opening operation of the weaving machine, improving the reliability of the device operation and the uniformity of the quality of the woven metal mesh.

[0064] Further, the spring 41 is a tension spring.

[0065] In this embodiment, the spring 41 is specified as a tension spring, which specifies the specific type of spring. The tension spring can better utilize the tension generated when it is stretched to counteract the gravity of the heald frame 2, and its characteristics are more suitable for cooperation with the structure of the device. In the installation, adjustment and actual operation process, it can more stably and effectively play the role of gravity balance, and compared with other types of springs (such as compression springs, etc.), it may be more suitable for the needs of the heald frame gravity balance of the side opening device of the metal mesh weaving machine, helping to improve the overall performance of the device.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
