Description

Technical Field

[0001] This utility model belongs to the field of circular knitting machine technology, and in particular relates to a height adjustment structure for the knitting machine's yarn frame. Background Technology

[0002] The yarn frame (also known as the "yarn frame" or "yarn feeding device") of a circular knitting machine is the core component of the equipment responsible for carrying, guiding and supplying yarn. Its design and function directly affect knitting efficiency, yarn tension stability and finished product quality. The main task of the yarn frame is to place and transport the cone yarn (or tapered yarn) in an orderly manner to the knitting area, while controlling the unwinding speed, tension and path of the yarn to ensure that multiple yarns enter the needle hook position synchronously and evenly.

[0003] Most existing methods of placing yarn cones are vertical, which may increase the friction between the yarn and the surface of the cone when the height of the circular knitting machine is the same as that of the yarn frame. This can easily cause a "dragging" phenomenon, especially at high speeds, resulting in tension fluctuations or even yarn breakage. To address this, we have developed a height adjustment structure for the yarn frame of a circular knitting machine. Utility Model Content

[0004] The purpose of this utility model is to provide a height adjustment structure for the yarn frame of a circular knitting machine. After the insert block disengages from the insertion slot, rotating the second locking block causes the support rod to rotate circumferentially, thereby adjusting the angle of the support rod. Then, the yarn is placed on top of the support rod to avoid yarn breakage. This solves the problem that when the height of the circular knitting machine is the same as that of the yarn frame, the friction between the yarn and the surface of the yarn may increase, especially at high speeds, which can easily cause a "dragging" phenomenon, resulting in tension fluctuations or even yarn breakage.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a height adjustment structure for a circular knitting machine's yarn frame, comprising a placement mechanism and placement rods. The outer surface of the placement mechanism is provided with an adjustment mechanism. Several placement rods are provided, and the top of each placement rod has a locking groove. Several locking grooves are provided, and a locking block is inserted into the inner wall of each locking groove. A connecting block is fixedly connected to the front of each locking block. By adjusting the angle of the support rod, the yarn package can be adapted to different situations.

[0007] Furthermore, the connecting block has an insertion slot inside, into which an insertion block is inserted. A second locking block is fixedly connected to the right side of the insertion block, and a rotating plate is rotatably connected to the right side of the second locking block. A second spring is fixedly connected to the right side of the rotating plate, and the right side of the second spring is fixedly connected to the inner wall of the connecting block. The rotating plate can be limited by the cooperation of the second locking block and the insertion slot.

[0008] Furthermore, a connecting block is fixedly connected to the inner wall of the connecting block, the outer surface of the connecting block is slidably connected to the inner wall of the second locking block, and a support rod is fixedly connected to the front of the second locking block.

[0009] Furthermore, the adjustment mechanism includes a support frame with an adding groove on its front side. The inner wall of the support frame is slidably connected to the outer surface of the placement rod. A connecting rod is slidably connected to the inner wall of the placement rod. The front side of the connecting rod passes through the placement rod and extends to the outside. A push rod is fixedly connected to the front side of the connecting rod, and a baffle is fixedly connected to the back side of the connecting rod. A spring is fixedly connected to the back side of the baffle, and the back side of the spring is fixedly connected to the inner wall of the placement rod. The spring rebound pushes the connecting plate to move forward, thereby causing the locking block to move.

[0010] Furthermore, a locking block is fixedly connected to the front of the baffle, and a locking groove is opened on the inner wall of the support frame. The inner wall of the locking groove is inserted into the outer surface of the locking block. A limiting rod is slidably connected to the right side of the placement rod. The top of the limiting rod is fixedly connected to the inner wall of the support frame. When the push rod is released, the spring rebounds, pushing the baffle to move forward so that the locking block is engaged in the locking groove to complete the adjustment of the height of the placement rod.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model uses a second locking block. Specifically, the second locking block is pulled to the right, causing the insert block to move and compress the second spring. After the insert block disengages from the insertion slot, the second locking block is rotated, causing the support rod to rotate in a circular motion to adjust the angle of the support rod. Then, the yarn is placed on top of the support rod to prevent yarn breakage.

[0013] 2. This utility model uses a locking block. Specifically, pushing the push rod backward causes the connecting rod to move, which in turn moves the baffle. The baffle then moves the locking block and compresses the spring. The placement rod is then pushed upward to stop at a suitable position. Finally, releasing the push rod causes the spring to rebound, pushing the baffle forward so that the locking block engages in the slot, thus adjusting the height of the placement rod.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Then, the push rod 102 is pushed backward, causing the push rod 102 to move the connecting rod 103. Then, the movement of the connecting rod 103 moves the baffle 104. Then, the movement of the baffle 104 moves the locking block 106 and compresses the spring 105. Then, the placement rod 201 is pushed upward to stop it in a suitable position. Then, the push rod 102 is released, causing the spring 105 to rebound and pushing the baffle 104 to move forward, causing the locking block 106 to engage in the locking groove 107 to complete the placement. The height of rod 201 can be adjusted, and the number of rods 201 can be adjusted according to the situation by adding slot 109. After the rods 201 are installed, a certain number of snap-fit ​​blocks 203 are selected and placed in snap-fit ​​slot 202 as needed. Then, snap-fit ​​block 206 is pulled to the right, which moves the insert block 208 and squeezes the spring 211. After the insert block 208 is disengaged from the insert slot 209, snap-fit ​​block 206 is rotated to make the support rod 205 rotate in a circle to adjust the angle of the support rod 205. Then, the yarn package is put on top of the support rod 205 to avoid yarn breakage.
