Description

Technical Field

[0001] The utility model relates to the technical field of a sock machine sinker cover, in particular to a sock machine sinker cover capable of reducing driving errors. Background Art

[0002] In the process of manufacturing and application of sock machines, the sine wave cover is a key technology. The main function of the sine wave cover is to provide a motion trajectory for the sine wave plate when the sock machine is knitting socks. The traditional sine wave cover is installed horizontally relative to the sock tube of the sock machine, and is driven by gear meshing. The center hole of the gear is connected to the longitudinally installed drive motor, which leads to the sine wave cover structure with the drive motor as the boundary requiring a higher longitudinal installation spacing. This installation spacing requirement limits the installation of other parts of the sock machine. How to shorten the longitudinal installation space of the sine wave cover of the sock machine is the object of research by technicians in this field. In addition, for the traditional gear meshing drive, there is always a large meshing gap, which leads to the inaccuracy of the sine wave cover for the accuracy of the motion trajectory of the sine wave plate. How to improve the accuracy of the sine wave cover during the continuous reciprocating rotation is also the object of research by technicians in this field. Utility Model Content

[0003] The purpose of the utility model is to optimize the driving structure of the scorer cover to improve its rotation accuracy and reduce the height of the installation space in view of the defects and shortcomings of the prior art, reasonably solve the space limitation and driving accuracy problems that may occur during the installation of the traditional scorer cover, and provide a scorer cover for a sock machine that reduces driving errors.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a sock machine with a scissor cover that reduces driving errors, comprising a scissor cover body, wherein the side of the scissor cover body is connected to a transversely arranged driving device through a connecting piece, the driving device comprises a transverse motor and a screw nut device driven by the transverse motor, the screw nut device is connected to a driving rod, the driving rod is sleeved in a first limiting hole of the connecting piece, and the driving rod drives the scissor cover body to rotate. The scissor cover for a sock machine that reduces driving errors changes the installation direction of the transverse motor from the vertical longitudinal direction installation of the original technology to the horizontal transverse direction installation, thereby shortening the longitudinal installation spacing of the scissor cover, and solving the problem of the scissor cover being too high in the longitudinal space during the installation of the sock machine, and the screw nut device driven by the transverse motor drives the connecting piece to move forward and backward, generating a tangential force in the circumferential direction on the scissor cover body, and the scissor cover body can only rotate around the center of the circle when installed on the sock machine, and the tangential force provided by the connecting piece realizes the technical purpose of rotating the scissor cover body. The driving motion accuracy generated by the screw nut device driven by the transverse motor is obviously much higher than the traditional gear meshing accuracy, thereby improving the precision control of the scissor cover on the motion trajectory of the scissor plate.

[0005] The screw nut device includes a screw driven by a transverse motor and a screw nut seat. The screw nut seat is provided with an axial first mounting hole and a screw nut that matches the screw. A mounting groove parallel to the screw is provided on the outer side of the screw nut seat. A guide block is installed in the mounting groove. The guide block and the screw nut seat are connected to form an integrated structure, which greatly improves the integrity of the screw nut device.

[0006] The guide block is a U-shaped structure, and the two arms of the U-shaped structure are fixedly connected to the screw nut seat by a screw, and the middle of the U-shaped structure is embedded with a connecting drive rod; the tops of the two arms of the U-shaped structure are provided with flanges, and a limit plate is provided between the flange and the slot arm of the installation slot, and the limit plate is fixedly connected to the motor bracket, and the motor bracket is fixedly installed with the transverse motor, and the limit plate is provided with a limit slot hole, and the guide block is embedded in the limit slot hole, and the guide block and the screw nut seat reciprocate along the limit slot hole under the rotation drive of the screw rod, and finally realize the motion performance of the connecting piece. The screw rod is driven to rotate by the transverse motor.

[0007] An end cover is provided at one axial end of the first mounting hole, and the other end cooperates with a coupling of the transverse motor, and the coupling and the end cover jointly limit the screw nut.

[0008] The limiting plate is provided with a first adjusting screw and a second adjusting screw on the sides of the limiting slot respectively for limiting the moving position of the guide block to adjust the movement stroke of the guide block. The first adjusting screw is threadedly connected to the second screw hole of the limiting slot, and the second adjusting screw is threadedly connected to the third screw hole of the limiting slot.

[0009] By adopting the above technical solution, the beneficial effects of the utility model are:

[0010] By changing the horizontal motor from the original longitudinal installation to the transverse installation, the longitudinal installation spacing of the hood is shortened, the layout flexibility and installation efficiency of the sock machine equipment are improved, while ensuring the function of the hood and solving the space limitation problem that may occur during the installation of the traditional hood.

[0011] The driving motion accuracy generated by the transverse motor driving the lead screw nut device is obviously much higher than the traditional gear meshing accuracy, thereby improving the precision control of the sinker cover on the motion trajectory of the sinker plate.
