Technical Field

[0001] The utility model relates to the technical field of cold mixers, in particular to a material mixing conveying device for a cold mixer. Background Art

[0002] In the production process of hair fiber, the production process is feeding, hot mixing, cold mixing, extrusion, spinning, drawing and shaping. The temperature of the raw materials will reach more than 100 degrees Celsius after hot mixing. The raw material temperature is too high to enter the next process directly, so it needs to go through an important production process, which is cold mixing. The purpose of cold mixing is to reduce the temperature of the hot mixed raw materials and to add some small molecule auxiliary materials.

[0003] The current cold mixing process is similar to the conventional mixing method, except that a cooling structure is added during the mixing process. However, the current cooling method generally uses air cooling, which has a low cooling efficiency and is easy to blow away smaller particles, resulting in a waste of raw materials. At the same time, it also increases the subsequent cleaning steps. Therefore, the utility model proposes a mixing conveying device for a cold mixer to improve the above problems. Utility Model Content

[0004] The utility model aims to provide a mixing material conveying device for a cold mixer, so as to solve the problem that the mixing component of the existing cold mixer has low cooling efficiency for raw materials as mentioned in the above background technology.

[0012] Preferably, the end of the stirring blade is a fan-shaped twisted structure, and the end of the scraper is a movable structure.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model accelerates the heat dissipation of hot raw materials in the mixing bin by arranging the heat dissipation edge and the heat dissipation bin, thereby accelerating the cold mixing progress. At the same time, a scraper structure is arranged to clean the inner wall of the mixing bin, thereby preventing a large amount of raw materials from adhering to the inner wall during the mixing process, thereby affecting the mixing degree.

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 implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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

[0023] See also Figure 1-4 , in the figure: This embodiment is a preferred implementation of the technical solution, a mixing and conveying device of a cold mixer, comprising a mixing bin 1; a heat dissipation edge 2 is integrally provided on the upper part of the mixing bin 1, and a heat dissipation bin 14 is provided at the bottom of the mixing bin 1, and a motor 15 is embedded in the middle of the heat dissipation bin 14, and the output shaft of the motor 15 is connected to a mounting seat 11, and the mounting seat 11 is movably arranged in the middle position of the mixing bin 1, and stirring blades 12 and scrapers 13 are installed at intervals on the peripheral side of the mounting seat 11, and the outer edges of the stirring blades 12 and the scrapers 13 are both in contact with the inner wall of the mixing bin 1;

[0024] It should be noted that: the mixing and conveying equipment of the cold mixer involved in the present application is mainly based on the cold mixing structure. By setting up a mixing bin 1 for storing hot raw materials, the motor 15 drives the mounting seat 11 to rotate, and the stirring blade 12 and the scraper 13 relatively fixed to the mounting seat 11 rotate synchronously. During the rotation of the stirring blade 12, the hot raw materials are continuously turned over to accelerate the mixing of the raw materials and the heat dissipation of the raw materials. The scraper 13 continues to contact the inner wall of the mixing bin 1 to scrape off the raw materials adhered to the inner wall of the mixing bin 1. During the mixing process, the heat stored in the hot raw materials in the mixing bin 1 is continuously dissipated, and under the low-temperature neutralization effect of the heat dissipation bin 14, the rapid heat dissipation of the hot raw materials is achieved.

[0025] Among them Figure 1 and Figure 2 As shown, the heat dissipation edge 2 is hollowed out in an annular shape, and the inner wall of the heat dissipation edge 2 is in contact with the inner wall of the mixing bin 1;

[0026] It should be noted that the hollow setting on the side of the heat dissipation edge 2 is used for air exchange between the inside of the mixing bin 1 and the outside, especially when an end cover is installed above the heat dissipation edge 2, the air exchange inside and outside the mixing bin 1 is used to accelerate the heat conduction of the mixed raw materials to achieve cooling of the hot material mixture.

[0027] The mixing bin 1 is provided with a discharge port on the peripheral side, and a bracket 4 is fixed to the outside of the discharge port, and a guide bin 5 is fixed to the bottom of the bracket 4, and the guide bin 5 cooperates with the external conveying structure; a cylinder 6 is fixed to the middle position of the outer side of the bracket 4, and a mounting plate 9 is fixed to the piston end of the cylinder 6, and an arc-shaped baffle 10 is fixed to the inner side of the mounting plate 9, and the arc-shaped baffle 10 cooperates with the discharge port; the mounting plate 9 is movably arranged inside the bracket 4, and a roller 8 is connected to the upper side of the mounting plate 9 via a shaft rod, and the roller 8 is provided with a guide rail 7, and the guide rail 7 is fixed to the upper side edge of the bracket 4;

[0028] It should be noted that the bracket 4 is used for installing and fixing the material guide bin 5 and the cylinder 6. The material guide bin 5 assists in the discharge of raw materials in the mixing bin 1 and guides them into the external conveying structure. The type of conveying structure is determined by the actual usage scenario and is not further restrictively described here. During the extension and retraction process, the piston end of the cylinder 6 drives the mounting plate 9 to move linearly, and the arc-shaped baffle 10 fixed relatively to the mounting plate 9 moves accordingly, and is attached to or separated from the discharge port, serving as a valve plate structure for the discharge of mixed raw materials and the closing of the discharge port. During the movement of the mounting plate 9, the roller 8 moves linearly along the guide rail 7 to balance the linear movement of the mounting plate 9.

[0029] Among them Figure 3 and Figure 4 As shown, an annular positioning plate 3 is fixed to the bottom of the mixing bin 1, and the annular positioning plate 3 is fixed to the external support surface; the heat dissipation bin 14 has a built-in condenser, and the condenser is arranged in close contact with the bottom of the mixing bin 1; the end of the stirring blade 12 is a fan-shaped twisted structure, and the end of the scraper 13 is a movable structure;

[0030] It should be noted that the annular positioning plate 3 is used for the installation and fixation of the entire equipment. Since the annular positioning plate 3 is located above the heat dissipation bin 14, during actual installation, a pillar structure is generally adopted to be connected to the mounting holes opened on the annular positioning plate 3 to raise the mixing bin 1 as a whole. The condenser tube structure provided in the heat dissipation bin 14 is a conventional heat dissipation structure. Its arrangement method and connection principle are not further described in detail here. The stirring blade 12 structure with a fan-shaped twisted structure can better turn the raw materials and facilitate the discharge of the raw materials from the discharge port. The scraper 13 structure with movable adjustment at the end can manually adjust its use angle according to its own wear to ensure the scraping effect on the inner wall of the mixing bin 1.

[0031] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make some simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
