Description

Technical Field

[0001] This application relates to the field of textile machinery technology, specifically a positioning mechanism for a ribbon weaving machine. Background Technology

[0002] Ribbon looms are important pieces of equipment in the textile industry, used to produce various ribbon products. They are widely used in the textile industry and are mainly used to produce various types of ribbons. With the rapid development of the textile industry, higher requirements have been placed on the precision and efficiency of ribbon looms.

[0003] In the process of webbing production, in order to ensure product quality, the webbing needs to be precisely positioned. However, the existing positioning mechanisms mainly use mechanical limit devices, which cannot meet the positioning accuracy requirements of high-precision webbing production and are not easy to maintain, affecting their use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a positioning mechanism for a ribbon weaving machine, which has the advantages of meeting the needs of high-precision ribbon production, simple structure, and easy maintenance. It solves the problems that the positioning accuracy of existing positioning mechanisms cannot meet the requirements of high-precision ribbon production, and that they are not easy to maintain, thus affecting their use.

[0005] To achieve the above objectives, this application provides the following technical solution: a positioning mechanism for a ribbon weaving machine, comprising a mounting frame, a motor being provided on the right side of the mounting frame, a drive wheel being fixedly connected to the output shaft of the motor, a timing belt engaging on the outer surface of the drive wheel, a positioning block being fixedly mounted on the outer surface of the timing belt by screws, a sensing plate being fixedly mounted on the upper surface of the positioning block, a limit block being fixedly connected to the back of the mounting frame, a sliding groove being provided on the right side of the limit block, a sliding block being slidably connected to the inner wall of the sliding groove, a fixing bolt being fixedly connected to the right side of the sliding block, a limit rod being threadedly connected to the outer surface of the fixing bolt, and a driven wheel engaging on the inner wall of the timing belt.

[0006] To improve positioning accuracy and meet production requirements, the above solution involves mounting positioning blocks on the surface of the synchronous belt with screws. The drive wheel is fixed to the output shaft of motor one, which enables the drive wheel to rotate. This connects the drive wheel, synchronous belt, and driven wheel. The rotation of the drive wheel causes the synchronous belt to move the positioning blocks. A limit block is fixed to the back of the mounting frame, and a sliding groove is formed therein. The sliding block is installed inside the sliding groove and connected to the fixing bolt by rotating the limit rod. When the positioning block moves the sensing plate, the surface of the sensing plate contacts the limit rod, achieving precise positioning. This ensures that the weaving machine maintains stable positioning accuracy during operation. The high positioning accuracy meets the needs of high-precision weaving production, and the structure is simple and easy to maintain.

[0007] Furthermore, a connecting rod is fixedly connected to the inner wall of the driven wheel, and a driving roller is fixedly connected to the outer surface of the connecting rod.

[0008] The above scheme involves installing connecting rod 1 on the inner wall of the driven wheel as a fixed connection, thereby enabling the installation of connecting rod 1. The driving roller is fixed on the surface of connecting rod 1, and the rotation of the driven wheel allows connecting rod 1 to rotate, which in turn allows the driving roller to rotate.

[0009] Furthermore, the outer surface of the connecting rod is rotatably connected to the inner wall of the mounting frame, and the outer surface of the drive wheel is rotatably connected to the inner wall of the mounting frame.

[0010] The above scheme connects the surface of connecting rod one to the inner wall of the mounting frame in a rotatable connection to limit the movement of connecting rod one. Similarly, it connects the surface of the drive wheel to the inner wall of the mounting frame in a rotatable connection to limit the movement of the drive wheel, thus enabling the drive wheel, timing belt and driven wheel to mesh stably.

[0011] Furthermore, a second connecting rod is rotatably connected to the inner wall of the mounting frame, and a driven roller is fixedly connected to the outer surface of the second connecting rod.

[0012] With the above scheme, the connecting rod 2 is set on the inner wall of the mounting frame and configured as a rotatable connection to limit the movement of the connecting rod 2. The driven roller is installed on the outer surface of the connecting rod 2 and configured as a fixed connection. When the connecting rod 2 rotates, the driven roller can rotate. The gap between the driving roller and the driven roller facilitates the passage of the webbing. The rotation of the driving roller and the cooperation of the driven roller can drive the webbing.

[0013] Furthermore, the inner wall of the mounting frame is fixedly connected to two support rods, and the bottom surface of the mounting frame is fixedly connected to a base plate.

[0014] The above solution involves fixing the support rod to the inner wall of the mounting frame as a fixed connection, and setting two support rods to improve the overall stability of the mounting frame. The base plate is fixed to the bottom surface of the mounting frame and fixed by welding to achieve the positioning and installation of the mounting frame.

[0015] Furthermore, a motor mount is fixedly connected to the upper surface of the base plate, and the upper surface of the motor mount is fixedly connected to the bottom surface of the motor.

[0016] By fixing the motor base to the upper surface of the base plate and connecting the upper surface of the motor base to the bottom surface of the motor, the motor can be supported, enabling the motor to operate stably.

[0017] Furthermore, a second motor is fixedly connected to the back of the limiting block, and a threaded rod is fixedly connected to the output shaft of the second motor.

[0018] The above scheme involves mounting motor 2 on the back of the limiting block and setting it as a fixed connection to achieve the positioning and installation effect of motor 2. Motor 2 is a micro motor, and the threaded rod is mounted on the output shaft of motor 2 and set as a fixed connection, so that the threaded rod can rotate through motor 2.

[0019] Furthermore, the outer surface of the threaded rod is rotatably connected to the inner wall of the limiting block, and the outer surface of the threaded rod is threadedly connected to the inner wall of the sliding block.

[0020] The above scheme connects the outer surface of the threaded rod to the inner wall of the limiting block in a rotating manner to limit the threaded rod. The sliding block is connected to the surface of the threaded rod in a threaded manner. By rotating the threaded rod, the sliding block can drive the limiting rod to move through the fixing bolt, which facilitates the limiting rod to release the limiting block.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This positioning mechanism for a ribbon weaving machine comprises components such as a synchronous belt, a positioning block, a sensing plate, and a limit rod. When a motor drives the drive wheel to rotate, the ribbon is transmitted. Through the connection of the drive wheel, synchronous belt, and driven wheel, the synchronous belt drives the positioning block to move, allowing the sensing plate to contact the limit rod. The cooperation between the positioning block and the limit rod achieves precise positioning, ensuring stable positioning accuracy during the operation of the ribbon weaving machine. This meets the needs of high-precision ribbon production and features a simple structure that is easy to maintain. When continued ribbon transmission is required, a second motor drives a threaded rod to rotate, which in turn drives a sliding block to move the limit rod. This allows the positioning block to continue moving under the action of the synchronous belt, ensuring continuous ribbon transmission. Attached Figure Description

[0032] Please see Figure 5The outer surface of the threaded rod 7 is rotatably connected to the inner wall of the limiting block 8, and the outer surface of the threaded rod 7 is threadedly connected to the inner wall of the sliding block 10. The connection between the outer surface of the threaded rod 7 and the inner wall of the limiting block 8 is configured as a rotatable connection to limit the threaded rod 7. The connection between the sliding block 10 and the surface of the threaded rod 7 is configured as a threaded connection.

[0033] This embodiment provides a positioning mechanism for a ribbon weaving machine. It includes components such as a synchronous belt 4, a positioning block 5, a sensing plate 6, and a limiting rod 12. When motor 2 drives the drive wheel 3 to rotate, the ribbon is transmitted. The connection between the drive wheel 3, the synchronous belt 4, and the driven wheel 13 allows the synchronous belt 4 to move the positioning block 5, thereby enabling the sensing plate 6 to contact the limiting rod 12. The cooperation between the positioning block 5 and the limiting rod 12 achieves precise positioning, ensuring stable positioning accuracy during operation. This meets the requirements of high-precision ribbon production and features a simple structure that is easy to maintain. When continued ribbon transmission is needed, motor 21 rotates the threaded rod 7, which in turn causes the sliding block 10 to move the limiting rod 12. This allows the positioning block 5 to continue moving under the action of the synchronous belt 4, ensuring continuous ribbon transmission.

[0034] It should be noted that the positioning block 5 and the timing belt 4 are connected by screws for easy replacement and installation. By setting the sensing plate 6, when the sensing plate 6 contacts the limit rod 12, the motor 2 can be stopped.

[0035] The working principle of the above embodiments is as follows: The webbing is placed between the driving roller 15 and the driven roller 17. The driving wheel 3 is rotated by the motor 2. The connection between the driving wheel 3, the synchronous belt 4, and the driven wheel 13 allows the driving roller 15 and the driven roller 17 to drive the webbing, thus realizing the transfer of the webbing. At this time, the positioning block 5 on the surface of the synchronous belt 4 moves to the designated position, and the surface of the sensing plate 6 contacts the surface of the limiting rod 12, causing the motor 2 to stop operating and achieving precise positioning of the webbing. When it is necessary to transfer again, the motor 21 is started, which allows the threaded rod 7 to rotate. Through the connection between the threaded rod 7 and the sliding block 10, the sliding block 10 slides on the inner wall of the sliding groove 9, thereby allowing the limiting rod 12 and the fixing bolt 11 to move with the sliding block 10, so that the positioning block 5 is not restrained. At this time, the motor 2 can be started again, so that the webbing can be transferred again.
