Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment, in particular to a spinneret for extruding polyester fibers. Background Art

[0002] Textile equipment refers to a type of machinery and equipment used for textile production, mainly used in yarn processing, weaving, knitting or printing and dyeing; spinnerets are one of the components of textile equipment and are used in the process of polyester fiber extrusion processing.

[0003] After searching, the patent document with patent publication number CN219793208U discloses a spinneret for polyester staple fiber production, comprising a fixed plate, a spinneret body passing through and provided at the bottom of the fixed plate, sliders fixedly connected to the front and rear ends of the spinneret body, a filter plate passing through and slidably connected to the middle position of the left and right sides of the filter box, a filter screen passing through and provided at the top and left and right sides of the filter plate, and a handle fixedly connected to the right side of the right baffle. First, the spinneret body is slid into the fixed plate, then the spinneret body is rotated to slide the slider in the fixed groove, and then a second bolt is screwed into the fixed plate and then into the slider to fix the spinneret body. The unmelted raw materials and impurities are filtered through the filter screen at the top of the filter plate. By pulling the handle, the handle drives the filter plate to move to the right, aligning the filter groove on the left with the feed pipe, and then cleaning the filter screen on the right.

[0004] However, it still has the following disadvantages in actual use:

[0005] The above-mentioned spinneret for polyester staple fiber production has a second hole on the side wall of the fixed plate, and the first hole on the fixed plate is connected to the second hole, and the slider is symmetrically connected to the peripheral side wall of the spinneret body, and the slider is provided with a screw hole, and the spinneret body is provided with a spinneret hole, and then the spinneret body is first slid into the interior of the fixed plate, and then the spinneret body is rotated to make the slider slide in the fixed groove, and then the spinneret body is fixed in the slider by screwing the second bolt into the fixed plate. However, the operation steps are cumbersome and multiple second bolts need to be rotated, thereby increasing the workload when replacing the spinneret body; 2. The above-mentioned spinneret for polyester staple fiber production passes through and is slidably connected to the filter plate in the middle position on the left and right sides of the filter box, and filter screens are passed through and provided on the left and right sides of the top of the filter plate. A handle is fixedly connected to the right side of the baffle on the right side, and the unmelted raw materials and impurities are filtered through the filter screen on the top of the filter plate. By pulling the handle, the handle drives the filter plate to move to the right, so that the filter groove on the left is aligned with the feed pipe, and then the filter screen on the right is cleaned. However, it is inconvenient to clean the blockage on the filter plate, which will reduce the filtering effect of the filter plate and affect the extrusion operation efficiency of the polyester staple fiber.

[0006] To this end, we provide a spinneret for polyester fiber extrusion to solve the above problems. Utility Model Content
