Yarn tension adjusting mechanism of flat knitting machine

Abstract

The utility model discloses a yarn tension adjusting mechanism of a flat knitting machine, and belongs to the field of textile equipment. Comprising an assembly frame; guide wheel frames are installed on the two sides of the interior of the assembling frame, and a lifting adjusting assembly is installed in the center of the interior of the assembling frame. The yarn tension adjusting mechanism of the flat knitting machine with the limiting structure has the beneficial effects that in the yarn conveying displacement process, a first limiting wheel frame located on the opposite face of a tension wheel frame can form attachment between two guide wheels due to elasticity of a first reset spring and guiding of a first guide groove and a first guide rod; at the moment, the yarn groove between the two guide wheels is located in a closed groove, it can be guaranteed that the yarn in the groove does not fall off in the conveying process, and even if the tension wheel frame conducts downward pressing adjustment on the yarn through the lifting adjustment assembly, due to the fact that the first limiting assembly and the first limiting wheel frame are both located at the front end of the same connecting frame, the yarn can not fall off. Therefore, the sealing of the yarn groove is not influenced.

[0005] There is no yarn tension regulating mechanism for a flat knitting machine with a limiting structure at present. Utility Model Content

[0006] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0007] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide a yarn tension adjustment mechanism for a knitting machine. During the working process or installation process, etc., due to the action of the limiting and anti-slipping mechanism, it has the beneficial effect of yarn limiting.

[0008] A yarn tension adjustment mechanism for a knitting machine comprises: an assembly frame; guide wheel frames are installed on both sides of the assembly frame, and a lifting and adjusting component is installed at the center of the assembly frame, the lifting and adjusting component comprises a connecting frame, and a tension wheel frame is fixed to the upper part of the front end of the connecting frame, a limited anti-slip mechanism is installed at the lower part of the front end of the connecting frame and the inner sides of the assembly frame, and reserved wire grooves 2 are opened at the lower parts of both sides of the assembly frame, the limited anti-slip mechanism comprises a limiting wheel frame 1, and the limiting wheel frame 1 is fixed to the lower part of the front end of the connecting frame, a limiting component 1 is installed on one side and below the limiting wheel frame 1, and a limiting component 2 is installed on both sides of the assembly frame.

[0009] Furthermore, the limiting component includes a guide groove, and the guide groove is opened on both sides of one side of the limiting wheel frame, a guide rod passes through the middle of the guide groove, and the end of the guide rod is connected and fixed with a fixed plate, the fixed plate is fixed to the inner bottom end of the connecting frame, and a return spring is installed above the fixed plate.

[0010] Furthermore, the guide grooves 1 opened on both sides of one side of the limiting wheel frame 1 and the guide rod 1 are slidably connected.

[0011] Furthermore, the second limiting component includes a side mounting frame, and the side mounting frame is symmetrically fixed on both sides of the inner side of the assembly frame, a return spring second is installed at the upper bottom of the side mounting frame, and the end of the return spring second is connected to a limiting wheel frame second, a guide groove second is opened at the four corners of the limiting wheel frame second, and a guide rod second is slidably provided through the middle of the guide groove second, and a reserved wire groove one is opened in the middle of one side of the side mounting frame.

[0012] Furthermore, the guide rod 2 and the guide groove 2 are symmetrically distributed along the vertical center axis of the limiting wheel frame 2, and the guide groove 2 and the guide rod 2 are movably connected.

[0013] Furthermore, the middle reserved opening of the reserved wire trough 1 is connected to the reserved wire trough 2.

[0014] Furthermore, the lifting and adjustment assembly includes a fixed frame, and the fixed frame is fixed on the upper part of the interior of the assembly frame, a motor is installed inside the fixed frame, and a transmission screw is installed at the output end of the motor, a screw sleeve is screwed on the periphery of one side of the transmission screw, and a connecting frame is fixed to the front end of the screw sleeve, and sliding rods for the connecting frame to slide are fixed on both sides of the middle part of the assembly frame.

[0015] Furthermore, the slide rods are symmetrically mounted on both sides of the transmission screw rod, and the heights of the slide rods and the transmission screw rod are the same.

[0016] The beneficial effect of the present application is that it provides a yarn tension adjustment mechanism for a knitting machine with a limiting structure. During the yarn conveying and displacement process, the limiting wheel frame 1 on the opposite side of the tension wheel frame will form a fit between the two guide wheels due to the elasticity of the reset spring 1 and the guidance of the guide groove 1 and the guide rod 1. At this time, the yarn groove between the two guide wheels is in a relatively closed groove, and the yarn in its groove can be guaranteed not to fall off during transportation. Even when the tension wheel frame presses the yarn downward through the lifting and adjusting component, since the limiting component 1 and the limiting wheel frame 1 are both located at the front end of the same connecting frame, the closure of the yarn groove will not be affected. The existence of the reset spring 1 mainly utilizes its own elasticity to facilitate the staff to place the yarn in the yarn groove, and the size of the yarn can basically be adapted in all directions. The structure and effect of the limiting component 2 on both sides of the assembly frame during operation are the same as the above-mentioned limiting component, so they will not be elaborated here.

[0017] The staff will pre-interlace and connect the yarn used by the knitting machine above the two guide wheel frames and below the tension wheel frame. When the device is in normal operation, the yarn will move with the cooperation of the transmission and the multiple guide wheels. However, during the operation, the yarn may become loose and fall off due to tension problems. At this time, the staff can start the motor in time to rotate the transmission screw. At this moment, the screw sleeve driven by the screw will carry the connecting frame and the tension wheel frame to cooperate with the slide rod to press down the yarn under the wheel. The yarn in this state can achieve effective tension tightening operation. BRIEF DESCRIPTION OF THE DRAWINGS

The staff pre-intersperses the yarn used for the knitting machine above the two guide wheel frames 2 and below the tension wheel frame 4. When the device is in normal operation, the yarn will move with the cooperation of the transmission and the multi-guide wheels. However, during the operation, the yarn may become loose and fall off due to tension problems. At this time, the personnel can start the motor 32 in time to rotate the transmission screw rod 33. At this moment, the screw rod slide sleeve 34 driven by the screw rod will carry the connecting frame 35 and the tension wheel frame 4 to cooperate with the slide bar 36 to press down the yarn under the wheel. The yarn in this state can achieve effective tension tightening operation.
