TECHNICAL FIELD
[0001] The utility model relates to the technical field of plastic recycling, especially to a structure for ring blowing and air cooling of spinning. BACKGROUND
[0002] Plastic products, such as plastic bottles, are common household garbage in life, and these plastic bottles are difficult to degrade in the plastic state. The current solution is to recycle these plastic bottles and then reuse them.
[0003] In the secondary utilization mode, the plastic bottles can be crushed into fragments, then rinsed clean, then impurity removal (impurities are removed by suspension due to the difference in density), then further impurity removal by material selection camera, then color selection camera to remove unwanted colors and retain plastic fragments of the desired color, then drying, melting and filtering to remove part of the impurities, then extrusion drawing, then cooling, then applying silicon oil to the spinning to prevent static electricity, and then bundling the spinning into a spinning bundle, cutting the spinning bundle during loading into the spinning frame, and placing the cut ends on the frame of the spinning frame, then expanding, oil immersion, water bath, steam heating, etc. to change the hard raw spinning into flexible cooked spinning. Finally, some polyester products are formed.
[0004] The formed polyester products can be cotton-type products of polyester staple fibers, which are mainly used in the cotton spinning industry. The products can be used for spinning alone or mixed with cotton, viscose fiber, hemp, wool, and vinylon, etc. The obtained yarn is mainly used for clothing weaving, and can also be used for home furnishing fabrics, packaging cloth, filling material, and thermal insulation material. Three-dimensional hollow products are mainly used for non-woven fabrics for medical and health care: surgical gowns, protective clothing, sterilization cloth, masks, and diapers; civilian non-woven fabrics, wet cloth, magic towel, beauty products, sanitary napkins, etc. Household non-woven fabrics: wall cloth, tablecloth, bed sheet, etc. Clothing non-woven fabrics: lining, adhesive lining, fluff, and shaped cotton, etc. Industrial non-woven fabrics: roofing waterproof roll material and asphalt base material, reinforcing material, polishing material, packaging bag, etc.; and can also be used as space cotton, thermal and sound insulation material, oil absorption felt, shoe material, and filling material for sofas and toys. Due to the high strength, wear resistance, acid and alkali resistance, high temperature resistance, and good electrical insulation of synthetic fibers, they have been widely used in various fields of the national economy, providing a broad prospect for the secondary utilization of plastic bottles.
[0005] The company has designed a new production line for the secondary utilization of plastic bottle fragments to produce polyester products. In this production line, improvements have been made to overcome the various shortcomings of the previous traditional production line (commonly used by many manufacturers).
[0006] The present scheme mainly improves the structure for cooling during extrusion drawing.
[0007] It should be noted that: when extruding drawing, the molten polyester material is passed into the cavity cylinder, a pressure plate is arranged at the bottom of the cavity cylinder, a plurality of small holes are opened on the pressure plate, when the pressure gas is passed into the cavity cylinder, the molten polyester material can be extruded from the small hole, so that the initial spinning (at this time, the initial spinning is only continuous molten material, the diameter of the initial spinning is consistent with the small hole) is obtained, and then the initial spinning is cooled to solidify, so that the spinning which is not easy to be pulled off is formed.
[0008] At present, the cooling method of the initial spinning generally has a side blowing method and a ring blowing method. The side blowing method is blowing cooling air from one side of the spinning, and the cooling method has simple structure, but the cooling effect of the side of the spinning facing the wind is good and the cooling effect of the side of the spinning facing away from the wind is poor. The ring blowing method is that the initial spinning extruded from the small hole passes through the cooling cylinder, and the cooling cylinder is arranged with cold air holes on the side, so that the spinning can be cooled at each column surface position, and the cooling effect is good, so many factories adopt the ring blowing method to solidify the initial spinning.
[0009] However, the commonly used ring blowing method is still not ideal: although the column surface of the spinning can be cooled, the distance from the air hole is inconsistent, so that the amount of wind received by each part of the spinning column surface is still inconsistent, if the amount of wind received by one side of the spinning is large, the cooling speed is fast, so that the cold shrinkage amount is large, which leads to poor effect of the whole spinning (i.e. the spinning is not straight).
[0010] And the scheme improves the corresponding structure on the basis of the ring blowing method, so that the initial spinning is well cooled, thereby improving the quality of the spinning (making the cross-sectional size of each position of the spinning consistent, and unable to make the spinning in a straight state). SUMMARY
[0011] The utility model discloses a structure for ring blowing cooling of spinning, solves the problem that the initial spinning pressed from the pressure plate is not good in circumferential cooling effect, thereby unable to guarantee the quality of the spinning.
[0012] It needs to be explained that the initial spinning yarn pressed out from the press plate is not solidified - just in continuous form, and the initial spinning yarn is cooled to be solidified into a flexible yarn. The initial spinning yarn is enlarged into an irregular long column with a certain diameter, and during the cooling process, the long column is cooled by the cooling gas, and the long column is cooled and shrinks. If one side of the long column is cooled and the other side is not cooled, the side cooled first will shrink - this will cause the spinning yarn to bend in this direction, although the other side will gradually cool and shrink later, but the spinning yarn is relatively curved and the cross-sectional size is different, which affects the quality of the spinning yarn.
[0013] Although there are some ring blowing cooling devices at present, the positions of the column surface of the spinning yarn are cooled at the same time, which improves the quality of the spinning yarn to a certain extent. However, in these ring blowing cooling devices, the cooling conditions at different positions in the device cannot be kept consistent, so the quality of the spinning yarn cannot be further improved.
[0014] If the cooling conditions at different positions in the ring blowing device are kept consistent through structural improvement, the quality of the spinning yarn can be further improved. The easily thought solution is to set a closed container, introduce cooling gas into the container, and make the cooling gas fill the whole container - so that the temperature at different positions in the container tends to be consistent (that is, to ensure that the cooling conditions are consistent), and when the spinning yarn passes through the container, the spinning yarn can be uniformly cooled (cooled in the environment with consistent temperature). The difficulty is that the spinning yarn is continuously produced, and the container cannot be closed.
[0015] Therefore, the present solution improves the conventional ring cooling device, forms a closed space in form as much as possible, and makes the cooling gas in the closed space in form, so as to cool the spinning yarn and improve the quality of the spinning yarn.

DETAILED DESCRIPTION
[0047] The utility model will be further described below in combination with the drawings, but the protection scope of the utility model is not limited to the following.
[0048] It should be noted that the orientation or positional relationship indicated by "left", "right" and the like is based on the orientation or positional relationship shown in the drawings, or is the orientation or positional relationship commonly used when the utility model product is used, or is the orientation or positional relationship commonly understood by those skilled in the art. Such terms are only used to facilitate the description of the utility model and simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.
[0049] It should be noted that the embodiments in the utility model and the features and technical solutions in the embodiments can be combined with each other without conflict.
[0050] It should be noted that when it is necessary to prepare the melted plastic into a spinning, the melted plastic is prepared through a pressure spinning machine, the pressure spinning machine has an inner cavity with a pressure, a distribution plate and a spinning plate are respectively arranged at the bottom of the inner cavity, the distribution plate is provided with holes, the melted plastic is first distributed to avoid being concentrated in one place, when the pressure gas is introduced into the inner cavity, the melted plastic passes through the spinning holes of the spinning plate to form continuous initial spinning (at this time, it has not been solidified). Then, the initial spinning needs to be cooled by a cooling mechanism to solidify the initial spinning.
[0051] However, the currently used cooling mechanism is a way of blowing from the side and a way of blowing along the spinning ring, neither of which can make the spinning in a relatively stable environment of temperature or cold air volume, thereby resulting in poor cooling effect of the spinning (see the part of the invention, which will not be repeated here).
[0052] Therefore, as Figures 1-6 shown, the embodiment discloses a structure for ring blowing cooling of spinning, which is arranged below the spinning mechanism 100, the spinning mechanism 100 has a spinning plate 10, the spinning plate 10 is in the form of a disc plate, and a plurality of spinning holes 11 are arranged at the outer ring edge of the spinning plate 10;
[0053] A first ring blowing part 20 is arranged directly below the spinning mechanism 100, the first ring blowing part 20 has a first cavity penetrating from top to bottom, a rotatable central cooling part 30 is arranged in the first cavity, and a spacing is formed between the inner wall of the first cavity and the central cooling part 30; a cold air hole A21 is arranged on the wall of the first cavity, the cold air hole A21 generates cold air A; the central cooling part 30 generates rotating and obliquely downward cold air B;
[0054] A second ring blowing part 40 is arranged directly below the first ring blowing part 20, and a spacing D is formed between the lower end of the first ring blowing part 20 and the upper end of the second ring blowing part 40; the second ring blowing part 40 has a second cavity penetrating from top to bottom, and a plurality of cold air holes C41 are arranged on the wall of the second cavity, the cold air holes C41 generate obliquely upward cold air C;
[0055] Working: the initial filaments are extruded from the extrusion holes 11 of the presser plate 10, and are guided downward from the spacing between the central cooling part 30 and the first inner cavity to the first ring blowing part 20, and then guided downward to the second ring blowing part 40; in the first inner cavity of the first ring blowing part 20, cold air A and cold air B are blown, and the cold air B drives the cold air A to flow downward, while the second ring blowing part 40 generates cold air C which is inclined upward and prevents the cold air A and the cold air B from flowing downward, so that the cold air A and the cold air B fill the first inner cavity of the first ring blowing part 20 (at this time, the temperature of each part in the first inner cavity tends to be uniform), and when the cold air in the first inner cavity is sufficient, the excess cold air is discharged through the spacing D, so that the initial filaments are well cooled in the first inner cavity.
[0056] In addition, since the initial filaments only fall downward from the spacing between the central cooling part 30 and the first inner cavity, this falling manner also allows the initial filaments to be uniformly and well cooled (the traditional manner is to distribute the initial filaments in the entire ring blowing cavity).
[0057] In an advantageous embodiment, a spacing E is formed between the first ring blowing part 20 and the presser mechanism 100; when the cold air B and the cold air C are cut off and the cold air A and the cold air B fill the first cavity, a part of the cold air A and the cold air B are discharged from the spacing E.
[0058] In an advantageous embodiment, the rotatable central cooling part 30 is provided with an auger blade 3101. When the auger blade 3101 rotates, it not only allows the cold air A and the cold air B to flow downward, but also stirs the cold air in the first ring blowing part 20, allowing the cold air to be uniformly distributed in the first cavity of the first ring blowing part 20.
[0059] The first ring blowing part 20 is further described below.
[0060] Referring to Figure 5 , the first ring blowing part 20 includes a first cylinder 22.

The corresponding pressure cold air source passes low-temperature gas with pressure into the first ring cylinder cavity, and then the low-temperature gas is sprayed out through the cold air holes A21 to form the cold air A.
[0061] The central cooling part 30 is further described below.
[0062] Referring to Figure 5The central cooling section 30 comprises a central cylinder 31. The central cylinder 31 has a central cavity, and a plurality of cold air holes B32 are formed on the cylindrical surface of the central cylinder 31. The central cavity is connected to a corresponding pressure cold air source through a pipe. In addition, the central cylinder 31 is connected to a driving mechanism, and the outer cylindrical surface of the central cylinder 31 has auger blades 3101. When the central cooling section 30 is working: the pressure cold air source is connected to the central cavity, and the pressure cold air is sprayed downward through the cold air holes B32. Then, the auger blades 3101 act on the sprayed air to form the downwardly inclined cold air B.
[0063] Further, the mounting structure of the central cooling section 30 is further described.
[0064] Referring to Figure 3 and Figure 4 , in order to facilitate the fixed installation of the central cooling section 30, a blank area is provided on the pressing plate (10) from the center to the edge of a certain direction, that is, the area is not distributed with the pressing holes 11.
[0065] Referring to Figure 5 and Figure 6 , the upper end of the central cylinder 31 is mounted on the upper base 33, and the lower end is connected to the output motor 34. The upper beam is passed through the upper base 33, and the upper beam extends from the lower position of the blank area of the pressing plate 10. The output motor 34 is fixed on the lower base 35, and the lower base 35 is located below the second ring blowing section 40. The lower beam is passed through the lower base 35, and the lower beam also extends from the lower position of the blank area of the pressing plate 10.
[0066] Further, the mounting of the central cooling section 30 is further described.
[0067] Referring to Figure 6 , the upper end of the central cylinder 33 is inserted into the cavity opening of the recessed cavity 3301 in the upper base 33, and the recessed cavity 3301 is provided with an air inlet hole 3302 connected to the corresponding pressure cold air source through the air pipe. In addition, the upper base 33 is also provided with a rectangular hole 3303, and the upper beam passes through the rectangular hole 3303. Of course, the corresponding rectangular hole is also provided on the lower base 35, and the corresponding lower beam passes through the rectangular hole.
[0068] The second ring blowing section 40 is further described below.
[0069] Referring to Figure 5The second ring blowing part 40 comprises a second cylinder 42. A plurality of cold air holes C41 are formed in the inner wall of the second cylinder 42. The second cylinder 42 has a second cylinder cavity. The second cylinder cavity is communicated with the cold air holes C41 and is further communicated with a corresponding pressure cold air source. During operation, the corresponding pressure cold air source sends low-temperature gas into the second cylinder cavity, and then the low-temperature gas is sprayed out through the cold air holes C41 to form cold air C which is inclined upward. In addition, in order to prevent the cold air A and the cold air B from flowing downward, the flow rate of the cold air C in the vertical direction is greater than the flow rate of the cold air A and the cold air B flowing downward.
[0070] Further, the second cylinder 42 is further connected with a lifting mechanism 43, so that the size of the interval D is adjusted, and thus the amount of the cold air in the first cavity of the first ring blowing part 20 is adjusted.
[0071] The above embodiments only express the preferred embodiments, the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the utility model patent. It should be pointed out that for the ordinary skilled in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model.
