[0024] The utility model provides Figure 1 and Figure 2 A melt spinning device is shown, comprising:

[0025] A support frame 1 is provided, on which a spinning pot 11 is mounted, a metering pump 12 is fixedly connected to the bottom end of the spinning pot 11, a spinneret 13 is mounted to the bottom end of the metering pump 12, and one end of the spinneret 13 extends to the outside of the support frame 1, a heater 15 is sleeved on the outside of the spinning pot 11, and an openable pot cover 14 is mounted on the top of the spinning pot 11; and an auxiliary feed port is installed between the spinning pot 11 and the heater 15.

[0026] As can be seen from the above, when in use, the tank cover 14 is opened on the spinning tank 11, and the materials required for processing are added into the spinning tank 11. At this time, the materials in the spinning tank 11 are manually stirred for mixing of the materials, and other materials are added into the spinning tank 11 through the auxiliary feed port to ensure the correct proportion of the materials. Then the tank cover 14 is closed, and the heater 15 is started to heat the temperature in the spinning tank 11, and then the materials in the spinning tank 11 are melted, and then the metering pump 12 quantitatively sucks the materials in the spinning tank 11, and then the sucked materials are transported to the spinneret 13, and then the materials are formed into filaments through the spinneret 13, and finally the filaments are cooled and solidified. The metering pump 12, the spinneret 13 and the heater 15 are all common components on the market, so they will not be elaborated here.

[0027] refer to Figure 1-Figure 3 As shown, the mixing and scraping assembly 2 is used to mix the materials in the spinning pot 11. The mixing and scraping assembly 2 includes a power stirring rod 21 installed on the tank cover 14 and a connecting seat 25 installed obliquely on the outside of the power stirring rod 21, and the connecting seat 25 is located in the spinning pot 11. A first scraper 26 is fixed at one end of the connecting seat 25, and the first scraper 26 is in contact with the spinning pot 11. A stirring plate 23 is also installed at one end of the connecting seat 25, and a disassembly assembly 3 for disassembling the connecting seat 25 is provided on the stirring plate 23. A mounting ring 22 is fixed at one end of the stirring plate 23, and the mounting ring 22 is sleeved on the outside of the power stirring rod 21. A cleaning assembly 4 is provided at the bottom end of the stirring plate 23, and the cleaning assembly 4 is used to clean the inner bottom wall of the spinning pot 11; two first stirring rods 24 are symmetrically fixed to the bottom end of the stirring plate 23, and a second stirring rod is fixed to the top of the stirring plate 23.

[0028] Through the above technical solution:

[0029] Before the material is melted, the tank cover 14 is first removed from the spinning tank 11, and the material is added into the spinning tank 11, and then the tank cover 14 and the spinning tank 11 are closed. At this time, the power stirring rod 21 drives the mounting ring 22 to rotate in the spinning tank 11, and the rotation of the mounting ring 22 drives the stirring plate 23 to rotate. The stirring plate 23 stirs the material around the mounting ring 22, and the rotation of the stirring plate 23 drives the first stirring rod 24 and the second stirring rod to rotate, so that the first stirring rod 24 and the second stirring rod are located in the spinning tank 11 and scraped between the material. The position of the material is continuously changed under continuous rotation, so that the material is strongly turned over. At the same time, the connecting seat 25 and the first scraper 26 move the material around the inner wall of the spinning tank 11 under the rotation of the stirring plate 23, so that the material is fully mixed in the spinning tank 11. After the material is melted and discharged, the power stirring rod 21 rotates to drive the mounting ring 22 and the stirring plate 23 to rotate, and then the stirring plate 23 rotates to drive the connecting seat 25 to rotate synchronously. At this time, the connecting seat 25 rotates to drive the first scraper 26 to rotate along the inner wall of the spinning pot 11, and the first scraper 26 rotates to scrape the material adsorbed on the inner wall of the spinning pot 11, so that the material is separated from the spinning pot 11, thereby not only achieving uniform mixing of the material in the spinning pot 11, shortening the material mixing time, and reducing the labor intensity of the user, but also scraping the spinning pot 11, which can reduce the residual material in the spinning pot 11 and prevent excessive accumulation of material on the inner wall of the spinning pot 11 to affect the material discharge efficiency, which can greatly improve the production efficiency of the device, and can reduce the loss of filaments during production, thereby reducing the production cost of medical sutures.

[0030] Further, regarding the above-mentioned disassembly assembly 3, as Figure 3 As shown, the disassembly and assembly component 3 includes a threaded hole 33 opened on the stirring plate 23 and the connecting seat 25 and a threaded rod 32 screwed in the threaded hole 33, one end of the threaded rod 32 extends to the outside of the threaded hole 33 and is fixed with a rotating disk; based on this, when the material transportation is completed, the tank cover 14 is removed from the spinning tank 11, and then the connecting seat 25 and the first scraper 26 are taken out of the spinning tank 11, and the threaded rod 32 is driven to rotate by rotating the rotating disk. At this time, the threaded rod 32 is rotated and disengaged along the threaded hole 33, and the limiting function between the connecting seat 25 and the stirring plate 23 is lost, and then the connecting seat 25 and the first scraper 26 are taken out on the stirring plate 23, so that the first scraper 26 can be disassembled, cleaned or replaced, so as to avoid the situation where material remains on the surface of the first scraper 26 for a long time, causing uneven material removal.

[0031] Furthermore, a positioning groove 31 for inserting the connecting seat 25 is also provided at one end of the stirring plate 23, and the size of the positioning groove 31 is consistent with that of the connecting seat 25, and the positioning groove 31 is communicated with the inside of the threaded hole 33; based on this, through the setting of the positioning groove 31, the connecting seat 25 and the stirring plate 23 can be positioned and installed, which can prevent the position of the connecting seat 25 from being shifted during installation, and reduce the installation difficulty between the connecting seat 25 and the stirring plate 23.

[0032] In addition, refer to Figure 1 , Figure 2 and Figure 4 As shown, the cleaning assembly 4 includes a second scraper 42 installed at the bottom end of the first stirring rod 24 and a connecting rod 41 fixed to the top end of the second scraper 42. An adjustment groove for inserting the connecting rod 41 is provided at the bottom end of the first stirring rod 24, and a pin assembly for connecting the connecting rod 41 is provided on the first stirring rod 24; the pin assembly includes a plurality of pin holes 44 provided on the first stirring rod 24 and a through groove provided on the top of the connecting rod 41, a pin column 45 is inserted on the first stirring rod 24, and the pin column 45 is inserted into the through groove corresponding to the pin hole 44 through the pin hole 44.

[0033] Through the above technical solution:

[0034] After the material is discharged, the power stirring rod 21 rotates to drive the mounting ring 22 and the stirring plate 23 to rotate, and the stirring plate 23 rotates to drive the first stirring rod 24 to rotate synchronously, and then the first stirring rod 24 rotates to drive the connecting rod 41 to rotate. At this time, the connecting rod 41 rotates to drive the second scraper 42 to rotate, and the second scraper 42 rotates and scrapes against the inner bottom wall of the spinning pot 11, so that the material adsorbed on the inner bottom wall of the spinning pot 11 is pushed and shoveled, so that the residual material on the inner bottom wall of the spinning pot 11 can be scraped, which can prevent the occurrence of cleaning dead corners when the material is scraped, further improve the cleaning effect of the spinning pot 11, reduce the residual material in the spinning pot 11, and facilitate the subsequent use of the spinning pot 11.

[0035] Furthermore, a plugging pad 43 is installed on the first stirring rod 24 to close the first stirring rod 24 and the plugging pad 43 is adapted to the plugging hole 44. Based on this, the plugging pad 43 is provided and the plugging pad 43 is fixed to the plugging hole 44 to block the remaining plugging holes 44. The plugging pad 43 can be pulled out from the plugging hole 44 when necessary to prevent the remaining plugging holes 44 from entering materials when they are not in use, thereby enhancing the protection of the plugging holes 44.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
