Description

Technical Field

[0001] This application relates to the field of components for textile equipment, and in particular to a stable connection structure for a dual-system overhead bridge on a textile machine. Background Technology

[0002] In existing textile machines, the two sets of heald frames are mostly driven by independent drive structures. Although the undulation speed and frequency of each heald frame can be adjusted independently, the heald frames do not have a linkage structure. Before use, the parameters need to be set and adjusted, which can easily lead to the upper and lower healds not separating. Utility Model Content

[0003] The purpose of this application is to provide a stable connection structure for a dual-system overhead bridge of a textile machine that is equally flexible in adjustment and easier to debug.

[0004] To achieve the above objectives, this application provides a stable connection structure for a dual-system overhead bridge on a textile machine: It includes a pair of fixedly mounted configuration frames, with a pair of swing frames rotatably connected between the two configuration frames. Each swing frame includes a pair of parallel connecting handles, and a pair of parallel push-pull shafts are fixedly connected between the two connecting handles. The opposite end faces of the two connecting handles have coaxial end shafts, which are adapted to cooperate with the configuration frames to form a rotating pair. It also includes a linkage rod, with bushings at both its upper and lower ends. The bushing at the upper end of the linkage rod cooperates with the push-pull shaft of the upper swing frame to form a rotating pair, and the bushing at the lower end cooperates with the push-pull shaft of the lower swing frame on the same side to form a rotating pair, ensuring the synchronicity of the upper and lower swing frames.

[0005] As a preferred embodiment, each of the configuration frames initially has two shaft holes with parallel axes, located near the upper and lower ends of the configuration frame, respectively, for the insertion of two end shafts to restrict the degrees of freedom of the swing frame.

[0006] As a preferred embodiment, the configuration frame is provided with a bearing in each of the shaft holes, and the end shaft rotates relative to the shaft holes through the bearings, thereby reducing the coefficient of friction and improving the smoothness of the swing frame's movement.

[0007] As a preferred embodiment, the two configuration frames are also bolted to end caps on opposite sides, which are suitable for restricting the position of the bearing within the shaft hole, thereby ensuring the stability of the configuration of each component.

[0008] As a preferred embodiment, the end cap includes an inner ring that is embedded in the shaft hole and abuts against the end face of the bearing. One end of the inner ring outside the shaft hole has a constraint plate with a through hole. The mounting bracket has a corresponding internal threaded hole, and the bolt passes through the through hole and engages with the internal threaded hole. One of the mounting brackets has a driver on its side facing away from the other mounting bracket. The output end of the driver is connected to the end shaft to drive the swing bracket to move.

[0009] As a preferred embodiment, a limiting ring is also fixedly connected to the outer side of the push-pull shaft, and the bushing is located between the limiting ring and the connecting handle and is restricted from sliding to ensure the stability of the linkage rod position.

[0010] As a preferred embodiment, each of the configuration frames has a positioning groove at its bottom and a connecting hole that extends through the left and right sides, through which a connector passes to fix the configuration frame to the textile machine frame.

[0011] As a preferred embodiment, the upper ends of the two configuration racks are fixedly connected by a bridging plate, which further improves the stability of the spacing between the upper ends of the two configuration racks.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing two sets of parallel swing frame structures, each swing frame has a pair of parallel push-pull shafts and is linked by a linkage rod. Only a single drive mechanism is needed to achieve flexible control and ensure the separation of heddles, making it more convenient to perform system debugging of the textile machine before operation.

[0014] (2) By setting a positioning groove and connecting hole structure at the bottom of the configuration frame and connecting a bridge plate at the top of the two configuration frames, the installation stability of the two configuration frames can be well guaranteed, thereby ensuring the movement stability of the swing frame.

[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0030] like Figure 1-10 The textile machine dual-system overhead bridge stable connection structure shown includes a pair of fixedly installed configuration frames 2. The two configuration frames 2 are parallel and their upper and lower ends are aligned. Each configuration frame 2 has a positioning groove 201 at its bottom for engaging with the positioning block on the textile machine frame, facilitating pre-positioning installation. The configuration frame 2 also has a connecting hole 202 near its bottom that passes through the left and right sides, allowing the connector to pass through and fix the configuration frame 2 to the textile machine frame. The upper ends of the two configuration frames 2 are also fixedly connected by a bridge plate 1. The bridge plate 1 has an L-shaped cross section, with one side resting on the top surface of the configuration frame 2 and the other side resting on the side of the configuration frame 2. There are usually two bridge plates 1, located on the symmetrical sides of the two configuration frames 2.

[0031] A pair of swing frames 6 are rotatably connected between two configuration frames 2. The swing frames 6 are parallel to each other and their ends are aligned. Each swing frame 6 includes a pair of parallel connecting handles 602. A pair of parallel push-pull shafts 603 are fixedly connected between the two connecting handles 602. The ends of the two push-pull shafts 603 are aligned. The opposite end faces of the two connecting handles 602 have coaxial end shafts 601. The end shafts 601 can cooperate with the configuration frame 2 to form a rotating pair. Specifically, each configuration frame 2 has two shaft holes 203. The axes of the two shaft holes 203 are parallel and close to the upper and lower ends of the configuration frame 2, respectively. The two shaft holes 203 on the two configuration frames 2 are also aligned. The two shaft holes 203 on each configuration frame 2 are respectively for the insertion of two end shafts 601. Each shaft hole 203 of the configuration frame 2 is provided with a bearing 3. The end shaft 601 rotates relative to the shaft hole 203 through the bearing 3, which has a low coefficient of rotational friction, making the swing frame 6 swing more smoothly.

[0032] Two mounting brackets 2 are also fixedly connected to end caps 4 on opposite sides by bolts 8, which are used to restrict the position of bearing 3 in shaft hole 203. End cap 4 includes an inner ring 401, which is embedded in shaft hole 203 to hold the end face of bearing 3. The end of inner ring 401 outside shaft hole 203 has a constraint plate 402. The constraint plate 402 has a through hole 403. The constraint plate 402 is rectangular. The through hole 403 is located at the four corners of the constraint plate 402. Mounting bracket 2 has a corresponding internal thread hole 204. Bolt 8 passes through the through hole 403 and engages with the internal thread hole 204 to achieve fixed installation of end cap 4.

[0033] The two swing frames 6 are connected by a linkage rod 7. Both the upper and lower ends of the linkage rod 7 have bushings 701. The bushing 701 at the upper end of the linkage rod 7 cooperates with the push-pull shaft 603 of the upper swing frame 6 to form a rotating pair. The bushing 701 at the lower end cooperates with the push-pull shaft 603 on the same side of the lower swing frame 6 to form a rotating pair. In this way, the upper and lower swing frames 6 can be linked. The outer side of the push-pull shaft 603 is also fixedly connected to a limit ring 604. The bushing 701 is located between the limit ring 604 and the connecting handle 602. The two ends of the bushing 701 are released from the connecting handle 602 and the limit ring 604 respectively, thus restricting the sliding. Therefore, the cooperation position between the linkage rod 7 and the two swing frames 6 can be kept stable.

[0034] In order to drive the two swing frames 6 to move synchronously, one of the configuration frames 2 is provided with a driver 5 on the side facing away from the other configuration frame 2. The driver 5 includes a servo motor and a reducer. The input end of the reducer is connected to the output end of the servo motor. The output end of the driver 5, that is, the output end of the reducer, is connected to the end shaft 601, which drives one swing frame 6. The other swing frame 6 connected by the linkage rod 7 will also move synchronously.

[0035] Working principle: During installation, the positioning groove 201 at the bottom of the configuration frame 2 is aligned with the positioning block on the textile machine frame. Then, a connector is used to pass through the connecting hole 202 at the bottom of the configuration frame 2 and fix it to the textile machine frame. The two swing frames 6, along with the push-pull shaft 603 located on the front side, rotate together to connect to the heald frame at the front of the textile machine, and the two swing frames 6, along with the push-pull shaft 603 located on the rear side, rotate together to connect to the heald frame at the rear of the textile machine. During operation, the driver 5 drives the entire swing frame 6 to deflect via the end shaft 601. The other swing frame 6, which is restrained by the linkage rod 7, will also deflect synchronously. When the front push-pull shaft 603 descends, the rear push-pull shaft 603 will inevitably rise, and at the same time, the front heald frame descends and the rear heald frame rises; when the front push-pull shaft 603 rises, the rear push-pull shaft 603 will inevitably descend, and at the same time, the front heald frame rises and the rear heald frame descends. Since the speed, rotational stroke and reversing frequency of the servo motor in the driver 5 are all controllable, the control system of the textile machine will be more flexible in adjusting the working parameters.
