Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic recycling, especially to a structure for oiling and bundling of spinning. BACKGROUND

[0002] Plastic products, such as plastic bottles, are common household waste 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 rinsed to remove impurities (impurities are removed by suspension due to the difference in density), then further removed by a material selection camera, then the color selection camera removes unwanted colors and retains plastic fragments of the desired color, then dried, then melted and filtered to remove some impurities, then extruded by ring blowing to form some polyester products.

[0004] The formed polyester products can be cotton-type products of polyester staple fibers, which are mainly used in the cotton spinning industry. The obtained yarn is mainly used for clothing weaving, and can also be used for home decoration fabric, 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, diapers; civilian non-woven fabrics, wet cloth, magic towel, beauty supplies, sanitary napkins, etc. Household non-woven fabrics: wall cloth, tablecloth, bed sheet, etc. Clothing non-woven fabrics: lining, adhesive lining, fluff, and shaped cotton. Industrial non-woven fabrics: roofing waterproof roll material and asphalt base material, reinforcing material, polishing material, packaging bag, etc.; 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, various deficiencies of the previous traditional production line (commonly used by many manufacturers) are improved. The present scheme mainly optimizes the mechanism for applying silicon oil after the completion of drawing.

[0006] It should be noted that when the molten plastic is formed into a filament by ring blowing, a subsequent processing process is performed: the filament is given silicon oil (static electricity is easily generated, and the silicon oil is used to avoid static electricity); then the filament is loaded into a can frame, when the can frame is filled with the filament, the filament is cut off, and the two ends of the cut-off filament are placed on the can frame; then the filament is stretched, immersed in oil, water bath, steam heating and other operations, so that the raw filament with hardness becomes flexible cooked filament.

[0007] At present, when the filament is given silicon oil, the method adopted is: adding silicon oil in water, and then spraying the silicon oil on the filament by using a nozzle on the conveying route of the filament. If the amount of water mixed with silicon oil sprayed is small, the effect of applying silicon oil to the filament may be poor; if the amount of water mixed with silicon oil sprayed is large, the filament is easily wetted, and a long static time is required for the subsequent cutting and loading of the filament in the can frame, so that the silicon oil can be attached to the filament, which affects the production efficiency. In addition, since the silicon oil is sprayed on the surface of the filament, the adhesion is not high, and the silicon oil is easily wiped off. SUMMARY

[0008] The utility model discloses a structure for oiling and bundling of a filament to overcome the shortcomings of the prior art and solve the problem of poor silicon oil application effect in the oiling and bundling process of the prior art.

[0009] It should be noted that after the molten plastic is filtered and spun, the filament is formed, and silicon oil needs to be applied to the filament to avoid static electricity. Generally, the method of applying silicon oil is to spray silicon oil on the filament by using a nozzle. Since the filament is thin, this method cannot allow all parts of a thin filament to be sprayed with silicon oil, and the silicon oil on the filament is not uniform by this method, and the silicon oil may be wiped off in the subsequent process, resulting in poor silicon oil application effect.

[0010] Therefore, the present application aims to evenly apply silicon oil to the filament and prevent the silicon oil from being wiped off.

[0011] The utility model discloses a structure for oiling and bundling of a filament to overcome the shortcomings of the prior art and solve the problem of poor silicon oil application effect in the oiling and bundling process of the prior art.

[0012] Further comprising a filament rolling guide part III arranged between the oiling part I and the bundling guide part II; the track oil dripping on the oiling part I can fall on the filament rolling guide part III.

[0013] The spinning rolling guide part III has a guide surface with a plurality of semispherical protrusions on the guide surface; and the spinning rolling guide part III is connected with the reciprocating mechanism IV;

[0014] The spinning is in vertical state from the protective cylinder, through the oiling part I, the spinning rolling guide part III, and the spinning is in contact with the semispherical protrusions on the guide surface; when the reciprocating mechanism IV drives the spinning rolling guide part III to reciprocate, the spinning reciprocates and rolls under the action of the semispherical protrusions, that is, rotates in the horizontal plane with the vertical direction as the central axis.

[0015] As the preferred technical solution of the application, the spinning rolling guide part III includes the second roller A and the second roller B, and the outer cylindrical surface of each of the two has a plurality of semispherical protrusions; the second roller A and the second roller B have their axes along the left-right horizontal direction, and the former is above the latter, and both are connected with the reciprocating mechanism IV, and both are connected with the second driving mechanism V for driving the rotation. When the spinning is guided upward and downward, the spinning first passes around the front cylindrical surface of the second roller A, and then passes around the rear cylindrical surface of the second roller B; when the second roller A and the second roller B rotate under the action of the second driving mechanism V and reciprocate left and right under the action of the reciprocating mechanism IV, the spinning can roll on the cylindrical surface of the second roller A and the second roller B, so that the silicone oil is wrapped on the surface of the spinning.

[0016] Further, the spinning rolling guide part III further includes a second back plate; the length of the second back plate is along the left-right horizontal direction, the width is along the up-down vertical direction, the second roller A and the second roller B are fixed on the front surface of the second back plate, the second driving mechanism V is fixed on the back surface of the second back plate, and the second driving mechanism V is connected with the second roller A and the second roller B through the driving auxiliary assembly, and the left and right ends of the second back plate are connected with the reciprocating mechanism IV.

[0017] Further, the number of the protective cylinders is multiple, and the number of the second roller A and the second roller B corresponding to the number of the protective cylinders is provided on the front surface of the second back plate.

[0018] Further, the number of the spinning rolling guide parts III is multiple.

[0019] As the preferred technical solution of the application, the oiling part I includes a first back plate, a first roller A and a first roller B. The length of the first back plate is along the left-right horizontal direction, the width is along the up-down vertical direction, the first roller A and the first roller B are arranged on the front surface of the first back plate, the first driving mechanism VI is arranged on the back surface of the first back plate, and the first driving mechanism VI is connected with the first roller A and the first roller B through the driving auxiliary assembly. The first roller A and the first roller B both have a hollow cavity, the cylindrical surface of each of the two has a plurality of small holes, and the rotating shaft end of each of the two is connected with the silicone oil feeding pipe through a rotating joint; the high-pressure silicone oil flows into the corresponding hollow cavity from the silicone oil feeding pipe, then flows out from the small holes, and finally contacts with the spinning.

[0020] Further, the first roller A and the first roller B are arranged in the protection frame.

[0021] As the preferred technical scheme of the present application, the bundle guiding part II comprises a third back plate and a small pulley; the small pulley is arranged on the front surface of the third back plate and is located directly below the corresponding protection cylinder. After the multiple filaments in one protection cylinder pass through the spinning rolling guiding part III, they all pass through the small pulley, so that the multiple filaments form a bundle.

[0022] Further, the bundle guiding part II further comprises a fourth back plate and a large pulley; the large pulley is arranged on the front surface of the fourth back plate, and the filament bundle formed by passing through the small pulley is again subjected to bundling by the large pulley.

[0023] In order to facilitate understanding, the working process of the present scheme is described as follows:

[0024] At the oiling part I, the downwardly pulled filaments are made to roll around the cylindrical surface of the first roller A and the first roller B, and the rotational linear speed of the first roller A and the first roller B is made to be greater than the descending speed of the filaments, that is, the filaments are made to produce relative movement with the outer cylindrical surface of the first roller A and the first roller B; and the outer cylindrical surface of the first roller A and the first roller B is provided with a hole for spraying silicon oil, so that the silicon oil is applied to the surface of the filaments by relative movement (if the filaments are regarded as a vertical rod, this application method only applies silicon oil to the position of the cylindrical surface on the front side or the rear side of the filaments, and the left side and the right side are not applied with silicon oil, so that subsequent processing is performed by the spinning rolling guiding part III);

[0025] At the spinning rolling guiding part III, the filaments also pass through the second roller A and the second roller B, at this time, the filaments produce the same relative movement with the second roller A and the second roller B as that at the first roller A and the first roller B, that is, the application of silicon oil is also achieved (the silicon oil at the spinning rolling guiding part III is dropped from the oiling part I); in addition, the second roller A and the second roller B also reciprocate along the axial direction, so that the filaments are pushed by the semispherical protrusions on the second roller A and the second roller B, so that the filaments are rotated, and thus the silicon oil is applied to each position of the cylindrical surface of the filaments, achieving uniform and good application of silicon oil to the surface of the filaments (at the spinning rolling guiding part III, in a simple way, the vertical filaments are made to move downward in the vertical direction relative to the outer cylindrical surface of the horizontally arranged corresponding roller, and the filaments are also made to roll on the outer cylindrical surface of the roller, so that the surface of the filaments is uniformly coated with silicon oil);

[0026] Referring to Figure 8 After the multiple filaments sequentially pass through the corresponding rollers of the protection cylinder, the oiling part I, the spinning rolling guiding part III and the bundle guiding part II, the multiple filaments are gradually integrated into a bundle.

[0027] The utility model has the following advantages:

[0028] (1) the spinning all parts are evenly wrapped with silicon oil, and the silicon oil is evenly wrapped, and the silicon oil effect on the spinning is good;

[0029] The traditional method of applying silicon oil to the spinning is to spray silicon oil on the spinning, and since the spinning is very thin, this spraying method cannot make the silicon oil evenly cover each part of the spinning, so the silicon oil effect is poor;

[0030] In the scheme, the oiling part I first applies some silicon oil to the surface of the spinning, and then the silicon oil drips down on the spinning rolling guide part III along the spinning, and the spinning moves downward relative to the corresponding roller at the spinning rolling guide part III (the spinning can move downward in the vertical direction relative to the roller, and the spinning can also roll on the outer cylindrical surface of the roller), so the surface of the spinning can be wrapped with silicon oil, and the silicon oil wrapped on the surface of the spinning is very uniform, and the silicon oil effect on the spinning is good;

[0031] (2) the small holes provided on the outer cylindrical surface of the corresponding roller at the oiling part I are beneficial to the dripping of the recombined silicon oil on the spinning rolling guide part III below;

[0032] When the spinning is wound around the cylindrical surface of the roller of the oiling part I, the lower cylindrical surface of the corresponding roller is not resisted by the spinning, so the silicon oil can directly drip downward through the small holes on the lower surface of the corresponding roller, thereby ensuring that there is sufficient silicon oil on the spinning rolling guide part III.

[0033] (3) the structure of the spinning rolling guide part III is relatively simple and easy to realize;

[0034] In the spinning rolling guide part III, two actions are mainly realized, i.e. the rotation of the corresponding roller and the reciprocating action of the corresponding roller left and right; by setting the second back plate, the second roller A and the second roller B are set on the second back plate, the reciprocating action mechanism IV drives the second back plate to realize the reciprocating action left and right, and the second roller A and the second roller B are connected with the corresponding driving mechanism through the corresponding belt pulleys.

[0049] 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.

[0050] It should be noted that the directions or positional relationships indicated by "left", "right" and the like are based on the directions or positional relationships shown in the drawings, or are the directions or positional relationships in which the utility model product is usually placed during use, or are the directions or positional relationships commonly understood by those skilled in the art. Such terms are only used for the convenience of describing the utility model and simplifying 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.

[0051] 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.

[0052] For example, Figures 1-7 ​As shown, a structure for oiling and bundling the filaments includes a protective cylinder 40, an oiling part I, a filament rolling guide part III, and a bundling guide part II arranged in sequence from top to bottom.

[0053] The filament rolling guide part III has a guide surface, and a plurality of semispherical protrusions 34 are arranged on the guide surface. In addition, the filament rolling guide part III is connected to a reciprocating mechanism IV.

[0054] In operation, the filaments are vertically drawn from top to bottom. Specifically, a plurality of filaments are drawn from the protective cylinder, and then the plurality of filaments are oiled in the oiling part I to achieve preliminary application of silicone oil (the silicone oil at the oiling part I will drip onto the guide surface of the filament rolling guide part III). Then, the filaments are in contact with the plurality of semispherical protrusions 34 on the guide surface of the filament rolling guide part III. When the reciprocating mechanism IV drives the filament rolling guide part III to reciprocate, the filaments reciprocate and roll under the action of the semispherical protrusions 34, i.e., the filaments rotate in the horizontal plane with the vertical direction as the central axis, so as to achieve 360° application of silicone oil on the filament cylindrical surface. Then, the plurality of filaments are bundled into a bundle of filaments by the bundling guide part II.

[0055] The oiling part I will be further described below.

[0056] Reference Figures 2-4 The oiling part I includes a first back plate 13, a first roller A11, and a first roller B12.

[0057] The first back plate 13 has a length along the horizontal direction and a width along the vertical direction. The first roller A11 and the first roller B12 are fixed to the front surface of the first back plate 13, and the axes of the first roller A11 and the first roller B12 are along the horizontal direction, with the first roller A11 above the first roller B12.

[0058] The first roller A11 and the first roller B12 are fixed to the first back plate 13 by a protective frame 16, and the protective frame 16 penetrates the first back plate 13. The first roller A11 and the first roller B12 have a plurality of small holes 14 on the cylindrical surface. The first roller A11 and the first roller B12 each have a hollow cavity, and the rotating shafts of the two are tubular. The left end of the rotating shaft is connected to a rotating joint 15, and the rotating joint 15 is connected to a silicone oil feeding pipe. High-pressure silicone oil sequentially passes through the silicone oil feeding pipe, the rotating joint 15, the rotating shaft, the hollow cavity, and the small holes 14.

[0059] Two auxiliary pulleys are arranged on the other end of the rotating shaft. An intermediate pulley C is arranged at the lower edge of the first back plate 13, an intermediate pulley D is arranged on the back surface of the first back plate 13, and a driving motor is also arranged on the back surface of the first back plate 13. Therefore, the auxiliary pulleys on the first roller A11 and the first roller B12, the intermediate pulley C, the intermediate pulley D, and the driving motor are sequentially connected by a belt.

[0060] When working, the spinning thread passes around the front cylinder surface of the first roller A11 and the rear cylinder surface of the first roller B12. The rotation speed of the first roller A11 and the first roller B12 is driven by the corresponding driving motor, and the linear speed at the cylinder surface of the first roller A11 and the first roller B12 is greater than the falling speed of the spinning thread, so that the spinning thread and the corresponding roller produce relative displacement. In addition, the silicone oil is sprayed out of the small hole 14, so that the silicone oil adheres to the spinning thread, and the sprayed track falls on the lower spinning rolling guide part III.

[0061] The spinning rolling guide part III will be further described below.

[0062] Referring to Figures 5-7 , the spinning rolling guide part III comprises a second roller A31, a second roller B32 and a second back plate 33.

[0063] The length of the second back plate 33 is along the horizontal direction, and the width is along the vertical direction. The second roller A31 and the second roller B32 are fixed on the second back plate 33, and the axes of the second roller A31 and the second roller B32 are along the horizontal direction, and the second roller A31 is above the second roller B32.

[0064] A plurality of semispherical protrusions 34 are arranged on the outer cylinder surface of the second roller A31 and the second roller B32.

[0065] In addition, the second driving mechanism V is fixed on the back of the second back plate 33, and the second driving mechanism V is driven by the driving auxiliary assembly and connected with the second roller A31 and the second roller B32.

[0066] In addition, the left and right ends of the second back plate 33 are connected with the reciprocating mechanism IV.

[0067] When the spinning thread is guided from top to bottom through the spinning rolling guide part III, the spinning thread first passes around the front cylinder surface of the second roller A31 and then passes around the rear cylinder surface of the second roller B32.

[0068] When the spinning rolling guide part III works, the second driving mechanism V drives the second roller A31 and the second roller B32 to rotate (so that the linear speed at the cylinder surface during rotation is greater than the falling speed of the spinning thread), and at the same time, the second roller A31 and the second roller B32 are driven to move left and right under the action of the reciprocating mechanism IV. Thus, two actions are generated, i.e. the spinning thread moves around the outer cylinder surface of the corresponding second roller A31 and second roller B32, and in addition, the spinning thread also rolls along the axial direction on the cylinder surface of the second roller A31 and the second roller B32. Since the silicone oil drops on the cylinder surface of the second roller A31 and the second roller B32, the two actions can make the silicone oil well adhere to the surface of the spinning thread. The semispherical protrusions 34 play a role in stirring the spinning thread.

[0069] Further, as shown in Figure 6 The driving of the second driving mechanism V is further described. The second roller A31 and the second roller B32 are fixed on the second back plate 33 through corresponding lug seats, and both have two auxiliary pulleys on the rotating shafts, and the second back plate 33 is provided with an intermediate pulley A at the lower end through another lug seat, an intermediate pulley B on the back of the second back plate 33, and a driving motor on the back of the second back plate 33; therefore, the auxiliary pulley on the second roller A31, the auxiliary pulley on the second roller B32, the intermediate pulley A, the intermediate pulley B, and the driving motor are sequentially connected through a belt.

[0070] Further, the reciprocating mechanism IV adopts an oil cylinder / gas cylinder with telescopic action.

[0071] In this scheme, in order to improve the effect of wrapping silicone oil, the number of the spinning roller guiding part III is multiple.

[0072] The bundle guiding part II is further described below.

[0073] Referring to Figure 1 , the bundle guiding part II includes a third back plate and a small pulley 21; the length of the third back plate is along the left-right direction, and the width is along the up-down direction, and two small pulleys 21 are arranged on the front surface of the third back plate, right below each protective cylinder 40. Referring to Figure 8 When the multiple filaments in one protective cylinder 40 pass through the spinning roller guiding part III, they all pass through the small pulley 21, so that the multiple filaments form a bundle.

[0074] Further, the bundle guiding part II further includes a fourth back plate and a large pulley 22; the length of the fourth back plate is along the left-right direction, and the width is along the up-down direction; the large pulley 22 is arranged on the front surface of the fourth back plate, and the filament bundle formed by passing through the small pulley 21 is again subjected to bundling by the large pulley 22. The fourth back plate is located at the left side of the third back plate.

[0075] In this embodiment, an oil receiving groove 50 is further arranged right below the third back plate, which receives the dripping silicone oil and then performs secondary recycling, which can be recycled to the oiling part I through a pump and a filtering mechanism.

[0076] The above embodiments only express the preferred embodiments, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
