Description

Technical Field

[0001] The utility model relates to the technical field of spinneret equipment, in particular to an anti-blocking type chemical fiber spinneret. Background Art

[0002] The spinneret is a commonly used product in the textile and chemical fiber industry. The spinneret includes a feed surface and a discharge surface. The feed surface is provided with a discharge hole. The main function of the spinneret is to transform the viscous polymer melt or solution into a thin flow with a specific cross-section through the feed hole, and pass through the coagulation medium to form a filament. When the existing spinneret is used, after the spinning work is completed, some solution or polymer melt will remain inside the spinneret hole of the spinneret, so when the temperature of the spinneret drops, the solution or polymer melt inside the spinneret hole will solidify and adhere to further block the spinneret hole, resulting in the spinneret hole being difficult to spray out uniform filaments or unable to spray out filaments when used next time.

[0003] For example, a utility model patent with authorization announcement number CN216304041U discloses a spinneret with an anti-clogging component. The device can effectively clear the blockage of the spinneret hole through the structure of a brush. Through the rotating structure of the connecting frame, the clearing device slides horizontally on the connecting frame, so that the clearing device can be moved to any position on the spinneret for clearing. Moreover, through the elastic structure of the lifting plate, the lifting plate can be close to the upper surface of the spinneret hole, and the brush can be inserted into the hole to better clean the deep blockage. The sliding rod structure can prevent the friction between the lifting plate, the brush and the spinneret hole from causing the lifting plate and the clearing device to be misaligned.

[0004] However, when the device is used, the cooled raw material is usually directly attached to the spinneret, and it is difficult to clean it only with a brush, which reduces the cleaning effect of the spinneret and cannot meet the use requirements well. Utility Model Content

[0005] The utility model aims to provide an anti-blocking type chemical fiber spinneret to solve the problems raised in the above background technology.

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

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figures 1 to 5 , a blockage-proof chemical fiber spinneret, comprising: a mounting sleeve 1, a spinneret 13 is mounted in the mounting sleeve 1, a protective cover 2 is also mounted on the upper end of the mounting sleeve 1, a feed pipe 11 is mounted on the right side of the mounting sleeve 1, a blowing port 121 is opened on the left side of the mounting sleeve 1, a baffle 122 is mounted at the position of the blowing port 121 through rotation of a rotating shaft, and a hot air pipe 12 is mounted at the position of the blowing port 121 on the left side of the mounting sleeve 1 corresponding to the blowing port 121; a tamping mechanism 3 is mounted on the protective cover 2, and is used to tamp the spinneret holes on the spinneret 13; a scraping mechanism 4 is mounted in the mounting sleeve 1, and is used to scrape the raw material at the lower end of the spinneret 13. In this embodiment, a torsion spring is also mounted on the rotating shaft, one side of the torsion spring is fixed to the baffle, and the other side of the torsion spring is fixed to the mounting sleeve, and the hot air pipe 12 is connected to an external hot air blower through a pipeline.

[0023] The working principle of the utility model is as follows: during cleaning, the hot air generated by the hot air blower enters the blowing port 121 through the hot air pipe 12, thereby causing the baffle 122 to rotate around the rotating shaft. At this time, the torsion spring is deformed (when the blowing of hot air stops, the torsion spring drives the baffle 122 to reset and blocks the blowing port 121), the blowing port 121 is opened, and the hot air enters the mounting sleeve 1, thereby heating the raw material on the spinneret 13 to soften it, which can effectively reduce the bonding strength between the raw material and the original spinneret 13, making it convenient to clean it out. After the residual raw material is softened, the residual raw material is pushed out of the spinneret hole by the tamping mechanism 3, so that it falls below the spinneret 13, and then the raw material at the lower end of the spinneret 13 is scraped off by the scraping mechanism 4, thereby effectively preventing the residual raw material from clogging the spinneret during subsequent use and affecting the processing effect of the product.

[0024] As a further solution, the tamping mechanism 3 includes a tamping electric push rod 31 installed at the upper end of the protective cover 2, the telescopic end of the tamping electric push rod 31 passes through the protective cover 2 and is fixed with a tamping lifting seat 33, and a plurality of tamping columns 34 are distributed and installed at the lower end of the tamping lifting seat 33. A tamping guide rod 32 is also slidably inserted at the upper end of the protective cover 2, and the lower end of the tamping guide rod 32 is fixedly connected to the upper end of the tamping lifting seat 33. The tamping columns 34 correspond one by one to the spinneret holes on the spinneret plate 13. In order to facilitate the insertion of the tamping columns 34 into the spinneret holes, a chamfer 35 is provided at the lower end of the tamping columns 34.

[0025] The working principle of the tamping mechanism 3 is as follows: when the spinneret hole needs to be tamped, the tamping electric push rod 31 is extended to push the tamping lifting seat 33 downward, so that the tamping column 34 at the lower end of the tamping lifting seat 33 is inserted into the spinneret hole, and then the raw material remaining in the spinneret hole is pushed out of the spinneret hole and falls below the spinneret plate 13, thereby completing the tamping work.

[0026] As a further solution, the scraping mechanism 4 includes a pair of scraping screws 42 rotatably installed in the mounting sleeve 1, and a scraper 43 is threadedly mounted on the scraping screw 42. The rear side of the scraping screw 42 passes through the mounting sleeve 1 and is fixed with a scraping pulley 44, and a scraping belt 45 is mounted between the scraping pulleys 44. A scraping motor 41 is also installed on the front side of the mounting sleeve 1, and the output end of the scraping motor 41 is drivingly connected to the shaft end of the scraping screw 42, and the upper end of the scraper 43 is in contact with the lower end of the spinneret 13.

[0027] The working principle of the scraping mechanism 4 is: when scraping, the scraping motor 41 is started, and the scraping motor 41 drives the scraping screw 42 to rotate, so that the scraping pulley 44 cooperates with the scraping belt 44 to drive another scraping screw 42 to rotate synchronously, so that the scraper 43 threadedly mounted on the scraping screw 42 moves to scrape the raw material at the lower end of the spinneret 13.
