Description

Technical Field

[0001] The utility model belongs to textile machinery and equipment, in particular to an encoder device and a warp knitting machine which are easy to disassemble and assemble. Background Art

[0002] The speed measuring encoder is a sensor device specially used to measure the speed of rotating objects. It converts the rotational motion of the mechanical shaft into an electrical signal (usually a digital pulse or coded data) to achieve accurate measurement of the speed. In the field of textile machinery, in order to ensure the stability of the warp knitting process and product quality, it is necessary to accurately monitor the speed of key parts such as the comb, needle bed or yarn feeding system of the warp knitting machine.

[0003] When encoders widely used on the market are installed on precision mechanical equipment such as warp knitting machines, they are usually fixed directly to one end of the area to be detected by screw thread connection or welding process. On the one hand, the entire encoder device inevitably protrudes outward from the main structure of the warp knitting machine, resulting in an increase in the overall space occupied by the equipment. The narrow operating space may not only affect work efficiency, but may also cause equipment damage or personal injury due to accidental contact or misoperation, which invisibly increases the safety hazards at the production site. On the other hand, the existing encoder fixing method is structurally coaxially connected to the rotating shaft to be detected. Although this direct connection structure ensures the accuracy of the relative position between the two, it causes the encoder to be subject to more frequent vibrations, which affects its service life. Utility Model Content

DETAILED DESCRIPTION

[0020] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0021] See attached Figures 1 to 2 , an encoder device that is easy to disassemble and assemble, mainly used in a warp knitting machine, the warp knitting machine includes: a rotating shaft to be detected, a second synchronous wheel arranged at one end of the rotating shaft to be detected and kept coaxially rotating, and a synchronous belt sleeved on the first synchronous wheel 400 and the second synchronous wheel. The rotating shaft to be detected is selected from a comb bar, a knitting needle bed or a yarn feeding system of the warp knitting machine. The encoder device includes: a mounting seat 100, a fixed sleeve 200 mounted on the mounting seat 100, a connecting shaft 300 rotatably mounted on the fixed sleeve 200, a first synchronous wheel 400 fixedly mounted on the connecting shaft 300 and synchronously connected to the rotating shaft to be detected through a synchronous belt, an encoder 800 fixedly mounted on the fixed sleeve 200, and a flexible coupling 500 connecting the connecting shaft 300 and the encoder 800.

[0022] In this embodiment, the encoder device is connected through a synchronous belt, which facilitates the removal and installation of the encoder device. The user can reasonably arrange the position of the encoder device according to the structure of the warp knitting machine, provide a certain degree of operating space for the user, and increase the flexibility of the encoder device. In addition, the encoder device is connected to the shaft to be tested through the synchronous belt, so as to buffer the vibration of the shaft to be tested, thereby protecting the encoder 800.

[0023] In a further embodiment, the fixed sleeve 200 includes: a first mounting portion 210 fixedly mounted on the mounting seat 100 and suitable for mounting the connecting shaft 300, a second mounting portion 230 fixedly mounted on the first mounting portion 210 through a sleeve portion 220 and suitable for mounting the encoder 800, and the connecting shaft 300 and the encoder 800 are coaxially arranged so that the two can rotate synchronously, ensuring that the encoder 800 can accurately measure the rotation speed, angle, position and other information of the connecting shaft 300.

[0024] In a further embodiment, the connecting shaft 300 is eccentrically arranged on the first mounting portion 210 through a bearing, and the fixing sleeve 200 can rotate a predetermined angle relative to the mounting seat 100. By rotating the fixing sleeve 200, the distance between the first synchronous wheel 400 and the second synchronous wheel can be adjusted, that is, the tensioning function of the synchronous belt is realized, and the accuracy and stability of the synchronous belt transmission are ensured. When the adjustment is completed, the limit plate 120 is fixedly installed on the mounting seat 100 by bolts to fix the first mounting portion 210 and limit the rotation of the fixing sleeve 200.

[0025] In a further embodiment, a horizontal notch is provided on the connection end of the encoder 800, and a bolt corresponding to the notch is provided on the connection end of the flexible coupling 500. During assembly, the bolt of the flexible coupling 500 is aligned and inserted into the notch of the connection end of the encoder 800, and the two can be fixedly combined by rotating the bolt. When disassembly is required, the reverse operation is performed, the bolt is loosened to disengage from the notch, and the encoder 800 and the flexible coupling 500 can be easily separated. The structural stability of the encoder device during operation is ensured, and the disassembly and assembly efficiency of the encoder device during maintenance or replacement is greatly improved.

[0026] In a further embodiment, the flexible coupling 500 is a bellows coupling, so that in the case of angular deviation or vibration, the torque can still be reliably transmitted and the synchronous rotation of the two shafts can be maintained, and the relative displacement between the shafts can be adapted and compensated to a certain extent, so as to further protect the encoder 800. In particular, the uniform elastic deformation of the bellows coupling ensures the uniformity and accuracy of torque transmission, reduces torque pulsation, and ensures the accuracy of the encoder 800 in detecting the rotation speed.

[0027] Among them, the bellows coupling is connected by a bellows, which is easily deformed by force, and the encoder device has relatively high flexibility and needs to be frequently disassembled and installed. When the bellows is easily subjected to axial load, it is easy to cause the bellows to be compressed, thereby affecting the use of the flexible coupling 500. Therefore, the connection method of the connecting shaft 300 is designed. Specifically, an annular protrusion 310 is formed circumferentially on the connecting shaft 300, and the first bearing 600 is clamped in the annular groove formed by one end of the protrusion 310 and the fixed sleeve 200; the second bearing 700 is arranged at the other end of the protrusion 310, and the outer edge of the second bearing 700 is flush with the outer edge of the fixed sleeve 200, and the second bearing 700 is limited by the fixing ring 710 fixed on the outer edge of the fixed sleeve 200 to prevent the connecting shaft 300 from relative movement, thereby protecting the bellows coupling.

[0028] In a further embodiment, a plurality of waist-shaped holes 110 are installed at the bottom and / or side of the mounting base 100 to facilitate the installation of the encoder device. Moreover, such waist-shaped holes can allow lateral displacement or angular adjustment of components within a certain range while maintaining good connection stability.

[0029] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
