Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transfer hook processing, in particular to a fixing mechanism for processing a transfer hook matched with a socks machine. Background Art
[0002] When producing socks, semi-finished socks are usually produced in the needle cylinder of the sock machine first, and the sock toes are not sewn at this time. Then the semi-finished socks are taken out of the needle cylinder by a transfer device and transferred to the seam head plate. After the seam head plate is closed, the sock toes are sewn. The transfer plate sleeve barb or transfer hook, transfer needle, and transfer tooth are the accessories in the transfer device.
[0003] Existing transfer hooks often have no notch structure. When the yarn is transferred from the transfer disk to the seam head disk, there is a possibility of thread derailment. Once the thread derails, the whole sock will be scrapped, or the operator needs to manually hang the thread needle by needle, which is very troublesome. Therefore, in order to prevent thread derailment, a notch structure needs to be processed at the end of the transfer hook. Since the notch structure exists on both sides of the end of the transfer hook, the transfer hook to be processed needs to be rotated and adjusted during processing. However, the existing clamping mechanism is often fixed and cannot be adjusted. It is not suitable for processing the end of the transfer hook, so it can only be processed by manual hand-held method. This method is very inefficient and cannot meet the needs. Summary of the invention
[0004] In order to solve the above-mentioned problem, the utility model designs a fixing mechanism for processing a transfer hook for a sock machine. The arranged swivel seat and the rotating drive mechanism can drive the clamping plate assembly to rotate accurately, thereby satisfying the processing of the notch structure at the end position of the transfer hook, thereby increasing the practical performance.
[0005] To solve the above technical problems, the present utility model provides a fixing mechanism for processing a transfer hook used in a sock knitting machine. The fixing mechanism is characterized in that it includes a clamping plate assembly and a base. The base is fixed on a workbench through connecting columns provided at the bottoms of the left and right ends. The lower end of the clamping plate assembly extends into a rotating seat and rotates therewith. The rotating seat is rotatably connected to the top of the base and is connected to a rotation driving mechanism. The lower end of the rotating seat is in an open shape. An outlet groove is formed in the base directly below the clamping plate assembly, and the outlet groove is directly above a transfer hook outlet conveyor belt. The clamping plate assembly is composed of a left clamping plate and a right clamping plate. Clamping grooves matching the transfer hook are formed on the side of the left clamping plate facing the right clamping plate and on the side of the right clamping plate facing the left clamping plate. The outer wall on the left side of the left clamping plate is fixed on the inner wall on the left side of the rotating seat. A clamping electric cylinder is installed on the outer wall on the right side of the rotating seat. The output shaft end of the clamping electric cylinder extends into the rotating seat and is connected to the outer wall on the right side of the right clamping plate through a transmission member. Notches are formed in the left clamping plate and the right clamping plate at positions corresponding to the parts to be processed at the end of the transfer hook. The right clamping plate is pressed against the left clamping plate by the driving of the clamping electric cylinder.
[0006] Furthermore: A pushing electric cylinder is installed on the outer wall on the left side of the left clamping plate. A first guiding through hole is formed in the left clamping plate at a position corresponding to the output shaft end of the pushing electric cylinder, and the first guiding through hole communicates with the clamping groove.
[0007] Still further: The rotation driving mechanism includes an external gear ring sleeved on the outer wall of the rotating seat, a servo motor, and a driving gear. The servo motor is installed on the outer wall of the base. The driving gear is sleeved on the output shaft of the servo motor, and the driving gear meshes with the external gear ring.
[0008] Even further: Four guiding columns are provided on the side of the left clamping plate facing the right clamping plate. The four guiding columns are horizontally arranged and are located on the front and rear sides of the clamping groove. Second guiding through holes matching the four guiding columns are formed in the right clamping plate at positions corresponding to the four guiding columns, and the right clamping plate is slidably connected to the guiding columns through the second guiding through holes.
[0009] After adopting the above structure, the beneficial effects of the present utility model are as follows:
