Description

Technical Field

[0001] This utility model relates to the field of nylon production technology, and in particular to a casting strip device for a nylon material production line. Background Technology

[0002] During operation, the pelletizer first delivers polyester melt at a constant pressure into a heated casting head. After being dispersed by a diffuser plate and evenly pressurized by a distribution plate, the melt is ejected by a spinneret to form multiple strands of molten plastic. Then, after water cooling and other processes, the melt is cut into pellets to achieve the desired effect.

[0003] Traditional heating methods for casting strip heads involve creating a circulating square cavity on the outside, then using a heat transfer medium heated by a coal furnace or natural gas, which is pressurized and pumped into the cavity to heat the diffuser plate, distribution plate, and spinneret inside the casting strip head, uniformly dividing the melt into plastic strips. However, this process results in some heat loss, increasing production costs. Furthermore, during extrusion, the nylon melt flows at different positions within the casting strip head, receiving varying amounts of heat, leading to differences in molding quality. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a nylon material production line casting strip device. This device addresses the problem that in the prior art, the heating method of the casting strip head is to make the outer surface into a circulating square cavity, and then use a heat medium heated by a coal furnace or natural gas, which is then pressurized and transported into the cavity by a pump to heat the diffuser plate, distribution plate and spinneret plate inside the casting strip head, so as to evenly divide the melt into plastic strips. However, this method causes a certain amount of heat loss during the transportation process, increases production costs, and results in different heat levels due to different flow positions of the nylon melt inside the casting strip head during extrusion, leading to differences in the molding quality during extrusion.

[0005] In view of this, the present invention provides a casting strip device for a nylon material production line, including a housing, a flange fixedly installed at one end of the housing, a nozzle fixedly installed at the other end of the housing, a stirring and heating assembly disposed inside the housing, and a heat insulation assembly disposed inside the housing;

[0006] The stirring and heating assembly includes an electric heating tube, a first stirring screw, a second stirring screw, a mounting bracket, a drive motor, a drive gear, and a driven gear. The electric heating tube is fixedly installed inside one end of the housing. The first and second stirring screws are partially rotatably connected to the inside of the housing. The mounting bracket is fixedly installed on the outside of one end of the housing. The drive motor is fixedly installed on one end of the mounting bracket. The drive gear is fixedly installed on the outer wall of one end of the first stirring screw shaft. The driven gear is fixedly installed on the outer wall of one end of the second stirring screw shaft.

[0007] Optionally, the electric heating tube is located between the flange and the first and second stirring screws.

[0008] Optionally, one end of the drive motor output shaft is fixedly mounted on one end of the first stirring screw shaft.

[0009] Optionally, the driving gear and the driven gear are located inside the mounting bracket, and the driving gear meshes with the driven gear.

[0010] Optionally, the heat insulation component includes a partition cavity, a liquid cavity, a support block, an inlet pipe, and an outlet pipe. The partition cavity and the liquid cavity are opened inside the outer shell. The support block is fixedly connected inside the partition cavity and the liquid cavity, respectively. The inlet pipe and the outlet pipe are fixedly connected to both sides of the outer shell, respectively.

[0011] Optionally, the diaphragm is located within the liquid cavity.

[0012] Optionally, one end of both the inlet pipe and the outlet pipe is connected to the liquid cavity.

[0013] As can be seen from the above technical solutions, the embodiments of this utility model have the following advantages:

[0014] 1. The present invention relates to a nylon material production line casting device, which, by setting up a stirring and heating component, specifically, heats the nylon raw material through an electric heating tube when it enters the shell, while driving the motor to rotate the first stirring screw, and simultaneously using the cooperation of the drive gear and the driven gear to drive the second stirring screw to rotate, thereby remixing the nylon material melt. It adopts a direct internal heating method, and stirring is performed after heating to reduce heat loss and ensure that the raw material is heated evenly, thereby improving the quality consistency of extrusion molding.

[0015] 2. The present invention relates to a nylon material production line casting strip device, which, by setting up a heat insulation component, specifically, uses a partition to separate the interior of the outer shell from the liquid cavity, and then uses an inlet pipe to deliver cold water into the liquid cavity, and has an outlet pipe for circulation.

Detailed Implementation

[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes in detail, with reference to the accompanying drawings, a nylon material production line casting device of the present invention.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of the casting strip device for a nylon material production line provided by this utility model includes a housing 1, a flange 2 fixedly installed at one end of the housing 1, a nozzle 3 fixedly installed at the other end of the housing 1, a stirring and heating assembly inside the housing 1, and a heat insulation assembly provided in the housing 1.

[0027] The stirring and heating assembly includes an electric heating element 401, a first stirring screw 402, a second stirring screw 403, a mounting bracket 404, a drive motor 405, a drive gear 406, and a driven gear 407. The electric heating element 401 is fixedly installed inside one end of the housing 1. The first stirring screw 402 and the second stirring screw 403 are partially rotatably connected to the inside of the housing 1. The mounting bracket 404 is fixedly installed on the outside of one end of the housing 1. The drive motor 405 is fixedly installed on one end of the mounting bracket 404. The drive gear 407... 406 is fixedly installed on the outer wall of one end of the first stirring screw 402 shaft, and driven gear 407 is fixedly installed on the outer wall of one end of the second stirring screw 403 shaft. Electric heating tube 401 is located between flange 2 and the first stirring screw 402 and the second stirring screw 403. One end of the output shaft of drive motor 405 is fixedly installed on one end of the first stirring screw 402 shaft. Drive gear 406 and driven gear 407 are located inside the mounting bracket 404, and drive gear 406 and driven gear 407 mesh with each other.

[0028] It should be noted that the stirring and heating assembly includes an electric heating tube 401, a first stirring screw 402, a second stirring screw 403, a mounting bracket 404, a drive motor 405, a drive gear 406, and a driven gear 407. Multiple stirring and heating assemblies can be arranged according to the size of the outer shell 1, so that they are distributed throughout the outer shell 1 to heat and mix the nylon material. When the nylon raw material enters the interior of the outer shell 1, it is heated by the electric heating tube 401. At the same time, the drive motor 405 drives the first stirring screw 402 to rotate. Simultaneously, the drive gear 406 and the driven gear 407 work together to drive the second stirring screw 403 to rotate, thus remixing the nylon material melt. It adopts a direct internal heating method, and stirring is performed after heating to reduce heat loss and ensure that the raw material is heated evenly.

[0029] Example 2

[0030] In some embodiments, such as Figure 3 , Figure 4 As shown, the heat insulation component includes a cavity 101, a liquid cavity 102, a support block 103, an inlet pipe 104, and an outlet pipe 105. The cavity 101 and the liquid cavity 102 are opened inside the outer shell 1. The support block 103 is fixedly connected to the inside of the cavity 101 and the liquid cavity 102 respectively. The inlet pipe 104 and the outlet pipe 105 are fixedly connected to both sides of the outer shell 1 respectively. The cavity 101 is located inside the liquid cavity 102. One end of the inlet pipe 104 and the outlet pipe 105 are both connected to the liquid cavity 102.

[0031] It should be noted that by setting up a partition 101 and a liquid chamber 102, which are supported by a support block 103, the partition 101 can first separate the interior of the outer shell 1 from the liquid chamber 102. Then, cold water is supplied to the liquid chamber 102 through the inlet pipe 104 and circulated through the outlet pipe 105. This not only forms a heat insulation layer on the outer shell 1 by the liquid chamber 102 and the partition 101 containing water, but also isolates the outer shell 1 from the outside, reducing the surface temperature of the outer shell 1 and preventing accidental burns to staff.

[0032] Working principle: When in use, the nylon raw material enters the shell 1 and is heated by the electric heating tube 401. At the same time, the drive motor 405 drives the first stirring screw 402 to rotate. Simultaneously, the active gear 406 and the driven gear 407 work together to drive the second stirring screw 403 to rotate, further mixing the nylon melt. This direct heating and mixing reduces heat loss and ensures that the raw material is heated evenly. Meanwhile, the partition 101 separates the interior of the shell 1 from the liquid chamber 102. Cold water is then supplied to the liquid chamber 102 through the inlet pipe 104 and circulated through the outlet pipe 105. This not only forms a heat insulation layer on the shell 1 by the liquid chamber 102 containing water and the partition 101, but also isolates the liquid chamber 102 from the outside environment, reducing the surface temperature of the shell 1 and preventing accidental burns to personnel.

[0033] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
