Description

Technical Field

[0001] The utility model relates to the technical field of leno thread processing, in particular to a leno wool thread forming device. Background Art

[0002] Leno refers to a yarn obtained by twisting multiple strands of coarse cotton or chemical fiber filaments. It has a certain elasticity and softness and is often used to make knitwear, sweaters, etc. The leno yarn forming device is generally manufactured by the heating and curing method, that is, after the yarn is stretched, it is cured and formed by high temperature heating, and then rolled into a product after cooling.

[0003] The existing leno yarn forming device mainly includes a stretching device, a heating device, a cooling device and a winding device. After the yarn is stretched by the stretching device, it is heated by the heating device, and then cooled by the cooling device. Finally, the formed yarn is wound by the winding device. The stretching device used is mainly a pinhole plate. The yarn is passed through the pinhole plate and stretched by the hole.

[0004] However, the size of the stretching holes on the pinhole plate is fixed, and different types of gauze yarns require different stretching degrees. Therefore, during the molding process, workers are required to manually replace pinhole plates with different stretching apertures, which reduces the efficiency of the molding process and also increases the workload of workers. Utility Model Content

[0005] The utility model aims to provide a leno yarn forming device with automatically adjustable stretching holes, which effectively solves the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0007] A forming device for leno yarn comprises a base and a top frame fixed on the base by means of columns, a stretching plate is installed on the base through a lifting and adjusting mechanism, and the lifting and adjusting mechanism is used to drive the stretching plate to be lifted and adjusted in the vertical direction; the stretching plate is provided with horizontally penetrating and tapered stretching holes at intervals from top to bottom, the inner diameter of the upstream port of the stretching hole is larger than the inner diameter of its downstream port; the inner diameter of the upstream port of the stretching hole and the inner diameter of the downstream port of the stretching hole gradually increase from top to bottom; a heating furnace, a cooler and a winding device are installed in sequence on the downstream side of the stretching plate above the base.

[0008] It can be seen that the utility model arranges stretching holes with different apertures at different heights on the stretching plate, and drives the stretching plate to be lifted and lowered in the vertical direction through the operation of the lifting and adjusting mechanism, and adjusts the stretching holes at different positions to the stretching working position, so that the gauze yarn can be stretched to different degrees to meet the processing needs of different gauze yarns, realizes automatic adjustment of the stretching aperture, does not require manual operation and replacement, improves the molding processing efficiency, and reduces the labor workload of the staff. The overall structural layout is reasonable and practical.

[0009] Furthermore, the lifting and adjusting mechanism includes an adjusting cylinder, which is vertically fixed to the upper surface of the base through a fixing frame, and a telescopic rod of the adjusting cylinder is fixedly connected to the bottom of the stretching plate.

[0010] By adjusting the telescopic operation of the air cylinder, the stretching plate is driven by the telescopic rod to move up and down, thereby achieving the lifting and lowering adjustment effect of the stretching hole.

[0011] Furthermore, an inlet and an outlet are respectively provided on both sides of the heating furnace, and both the inlet and the outlet are connected to the furnace cavity of the heating furnace; a heater is arranged on the inner wall of the furnace cavity.

[0012] The leno thread is introduced into the furnace cavity through the inlet and then led out through the outlet. The leno thread passing through the furnace cavity is processed by the heater inside the furnace cavity through electric heating, which is helpful for the shaping process of the leno thread.

[0013] Furthermore, reversing rollers are installed in the furnace chamber for rotation at intervals, and the reversing rollers are arranged in a staggered manner.

[0014] After entering the furnace chamber, the yarns will go around the reversing rollers in turn to change direction. The staggered arrangement of the reversing rollers can extend the heating time of the leno yarn in the furnace chamber, thereby ensuring that the leno yarn is heated more thoroughly and improving the quality of the leno yarn forming process.

[0015] Furthermore, a temperature controller electrically connected to the heater is installed on the outer surface of the heating furnace.

[0016] The heating temperature of the heater can be adjusted by operating the temperature controller, so that different temperatures can be set according to the diameter and material of the yarn to achieve the best heating effect.

[0017] Furthermore, guide grooves extending vertically and having a U-shaped cross section are fixed on both side surfaces of the stretching plate, guide bars are slidably mounted on the guide grooves, and the tops of the guide bars are fixedly connected to the lower surface of the top frame.

[0018] Through the sliding cooperation of the guide groove and the guide bar, a good wire limiting effect is provided for the stretching plate in the vertical direction, ensuring that the lifting process of the stretching plate is smoother and more stable.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0020] The utility model arranges stretching holes with different apertures at different heights of a stretching plate, and drives the stretching plate to be lifted and adjusted in a vertical direction through the operation of a lifting and adjusting mechanism, and adjusts the stretching holes at different positions to a stretching working position, so that the gauze yarn can be stretched to different degrees to meet the processing needs of different gauze yarns, and realizes automatic adjustment of the stretching aperture, does not require manual operation and replacement, improves the molding processing efficiency, and reduces the labor workload of the staff, and the overall structural layout is reasonable and practical.

[0021] In the utility model, after the yarn enters the furnace cavity, it successively bypasses the reversing rollers for reversing. The staggered arrangement of the reversing rollers can extend the heating time of the leno thread in the furnace cavity, thereby ensuring that the leno thread is heated more thoroughly and improving the quality of the leno yarn forming process.

[0029] When the device is used to form the leno yarn, the leno yarn is sequentially passed through the stretching hole 31, the heating furnace 5 and the cooler 6 and then connected to the winding device 7. The leno yarn is wound by the winding device 7. The leno yarn can be stretched and thinned through the stretching hole 31. Then, the stretched leno yarn is heated by the heating furnace 5 to facilitate the forming. Then, the heated leno yarn is cooled by the cooler 6 to complete the forming process of the leno yarn. Finally, the leno yarn is wound into a leno yarn product by the winding device 7. Since the apertures of the stretching holes 31 at different positions are different, when forming different leno yarns, the stretching plate 3 is driven to be lifted and lowered in the vertical direction by the lifting and adjusting mechanism 4, and the stretching holes 31 at different positions are adjusted to the stretching working position, so that the leno yarn is stretched to different degrees to meet the processing needs of different leno yarns.

[0030] Specifically, the lifting and adjusting mechanism 4 includes an adjusting cylinder 41, which is vertically fixed to the upper surface of the base 1 through a fixing frame 401, and a telescopic rod 411 of the adjusting cylinder 41 is fixedly connected to the bottom of the stretching plate 3.
