Description

Technical Field

[0001] This utility model relates to the technical field of yarn drafting devices, specifically a yarn drafting device for spinning machines. Background Technology

[0002] A drafting machine is a mechanical device used in the drafting and twisting process of yarn production. After the yarn spun by the spinning machine is drafted and twisted, it has a certain linear density, strength, elongation and other physical properties, and can be used directly or after texturing for weaving. Existing drafting machines usually have a take-up spool rotated and sleeved on a support rod, and then the take-up spool is driven to rotate by a drive roller. In order to ensure the stability of the take-up spool installed on the support rod, a positioning nut is usually threaded onto one end of the support rod to limit the position of the take-up spool.

[0003] Chinese Utility Model Patent Application Publication No. CN218147116U discloses a yarn drafting device for a spinning machine, including a mounting frame, a take-up coil sleeved on the outer wall of a support rod, the bottom of the take-up coil being in contact with a drive roller, and a positioning component on the support rod for limiting the position of the take-up coil. The positioning component includes a positioning collar and a positioning cap. The positioning collar is fixedly sleeved on the outer wall of the support rod, and the positioning cap is slidably sleeved on one end of the outer wall of the support rod. A connecting frame is fixedly sleeved on the outer wall of the support rod, and a fixing plate is provided at one end of the connecting frame. The bottom of one side of the fixing plate is fixedly connected to the positioning cap. This utility model utilizes the cooperative use of the support rod, the take-up coil, and the positioning component. The positioning cap and the positioning collar are located at opposite ends of the take-up coil, thereby ensuring the stability of the take-up coil mounted on the support rod. Furthermore, the fixing plate can be used to separate the positioning cap from the support rod, allowing for convenient installation or removal of the take-up coil. However, the adjustment of the take-up coil position is relatively inconvenient, which reduces the applicability of the take-up and unwinding process and affects the overall performance of the yarn drafting device for the spinning machine. Utility Model Content

[0004] The purpose of this invention is to provide a yarn drafting device for spinning machines, which solves the problem mentioned in the background art that the adjustment of the take-up position is inconvenient, resulting in a reduced range of applicable take-up and unwinding, and affecting the overall performance of the yarn drafting device for spinning machines.

[0009] Preferably, a fixing plate is fixedly provided on one side of the support plate, and a third electric push rod is fixedly provided at the bottom of the fixing plate.

[0010] The above solution allows for the adjustment of the mounting plate height by installing a third electric push rod.

[0011] Preferably, a mounting plate is fixedly provided at the bottom of the third electric push rod, and mounting brackets are fixedly provided on both sides of the bottom of the mounting plate.

[0012] The above solution allows the roller to rotate inside the mounting frame by setting up a mounting bracket.

[0013] Preferably, the mounting frame has a roller rotatably connected inside, and the roller is located above the take-up drum.

[0014] The above method involves setting up rollers to guide the yarn to wind onto the take-up drum.

[0018] The above solution, by setting a second limiting ring, prevents the yarn from crossing the bobbin.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The yarn drafting device for a spinning machine, through the combined action of a first electric push rod, a second electric push rod, a movable block, and a locking block, enables the movable block to move within the movable groove, thereby allowing the height of the servo motor and the take-up drum to be adjusted, improving the flexibility of the device adjustment and the take-up and unwinding effect of the take-up drum.

[0021] 2. This yarn drafting device for a spinning machine, through the combined action of a third electric push rod, a mounting plate, a mounting frame, and a roller, allows the height of the roller to be adjusted according to the height of the take-up drum. By limiting the yarn with the roller, the yarn is prevented from breaking during the drafting process, thus improving the efficiency of yarn drafting. Attached Figure Description
