Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic recycling, especially a silk containing auxiliary structure for containing and placing spun yarn. 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 impurities are removed by rinsing (impurities are removed by suspending due to the difference in density), then further impurities are removed by a material selection camera, then the color selection camera removes unwanted colors and retains plastic fragments of the desired color, then the plastic fragments are dried, melted and filtered to remove some impurities, then the plastic fragments are extruded by ring blowing, silicon oil is applied to the spun yarn to prevent static electricity, and the spun yarn is bundled into a spun yarn bundle, the spun yarn bundle is cut off and the cut end is placed on the frame of the silk containing frame during loading, then the spun yarn bundle is stretched, immersed in oil, water bathed, and steam heated to change the hard raw spun yarn into flexible cooked spun yarn. Finally, some polyester products are formed.

[0004] The polyester products formed can be cotton-type products of polyester staple fibers, which are mainly used in the cotton spinning industry. The products can be spun alone or blended with cotton, viscose fiber, hemp, wool, and vinylon, and 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; non-woven fabrics for civilian use, wet cloth, magic towel, beauty products, sanitary napkins, etc. Non-woven fabrics for household use: wall cloth, tablecloth, bed sheet, etc. Non-woven fabrics for clothing: lining, adhesive lining, fluff, and shaped cotton. Non-woven fabrics for industrial use: 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, 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 shortcomings of the silk containing frame.

[0007] It should be noted that: at the next floor of the floor where the silicon oil-coating device (coating the spinning with silicon oil and bundling the plurality of spinning into a bundle under the action of the silicon oil, i.e. the spinning bundle) is located, a spinning frame is placed, so that the spinning bundle can be loaded in the spinning frame; since the spinning bundle is continuously produced after being produced, it is necessary to cut the spinning bundle into a long section, then load the long section of the spinning bundle in the spinning frame, and then perform the next step. At present, the operation of cutting the spinning bundle into a long section is: one end of the spinning bundle is placed in the spinning frame, then the spinning bundle is continuously produced, and the spinning bundle falls into the spinning frame, when the spinning frame is almost full, the spinning being produced is manually cut off, and then the cut end is also placed in the spinning frame (i.e. a long section of the spinning bundle is loaded in one spinning frame); then the next spinning frame is replaced.

[0008] However, this way of placing the spinning bundle is messy because the spinning bundle is randomly stacked in the spinning frame. When the long section of the spinning bundle in the spinning frame needs to be subsequently drawn (straightened and then curled and heat treated), the long section of the spinning bundle needs to be straightened again, and occasionally the long spinning bundle may be wound in the spinning frame and cannot be completely straightened. At this time, it needs to be manually arranged and straightened, which affects the work efficiency. SUMMARY

[0009] The purpose of the present application is to overcome the shortcomings of the prior art and provide a spinning auxiliary structure for loading and placing spinning, which solves the problem of easy winding of the spinning frame when loading the spinning bundle.

[0010] It should be noted that when the spinning bundle is produced, it needs to be cut into a long section, and then the long section of the spinning bundle is stacked in the spinning frame, and the two ends of the long section of the spinning bundle are placed on the edge of the spinning frame. In the subsequent drawing work, the long section of the spinning bundle also needs to be straightened. At present, the long section of the spinning bundle is naturally stacked in the spinning frame, and when the spinning bundle is straightened subsequently, it is found that the naturally stacked spinning bundle is easy to wind.

[0011] The present application is designed by the corresponding auxiliary structure, so that the long section of the spinning bundle is stacked in the spinning frame in a certain order, so that the long section of the spinning bundle is not easy to wind when it is drawn in the subsequent drawing.

[0012] The purpose of the present application is achieved by the following technical scheme: a spinning auxiliary structure for loading and placing spinning, comprising a spinning frame, the spinning frame is arranged below the silicon oil-coating device, the spinning is coated with silicon oil and bundled into a spinning bundle, and then falls into the spinning frame for storage;

[0013] Further comprising:

[0014] The cutting mechanism I is arranged between the silicon oil-coating device and the spinning frame, and can cut the spinning bundle.

[0015] The left-right and front-back action mechanism II is connected with the frame for containing the filaments and can move left and right and also move forward and backward at the same time;

[0016] When the continuous filaments drop into the frame for containing the filaments, the left-right and front-back action mechanism II moves forward and backward step by step, and after each step, it moves left and right once, so that the filaments are folded and stacked in the frame for containing the filaments in a certain order.

[0017] As a preferred technical solution of the present application, when the left-right and front-back action mechanism II moves left and right, it can move to the leftmost position / rightmost position, so that the filaments drop close to the left inner wall / right inner wall of the frame for containing the filaments. After the left-right and front-back action mechanism II moves forward and backward step by step and moves left and right at the same time for a period of time, it will move to the leftmost position / rightmost position in the left-right direction, so that the filaments drop outside the frame for containing the filaments.

[0018] As a preferred technical solution of the present application, the left-right and front-back action mechanism II includes a steel frame moving seat and a moving plate frame. The bottom of the moving plate frame is provided with a roller A which is arranged on the front-back guide rail. The roller A is connected with a driving mechanism A. The bottom of the steel frame moving seat is provided with a roller B which is arranged on the left-right guide rail. The left-right guide rail is fixed on the upper surface of the moving plate frame. The roller B is connected with a driving mechanism B. The frame for containing the filaments is placed on the upper surface of the moving plate frame.

[0019] Further, a placing pit is formed on the ground, and the left-right and front-back action mechanism II is arranged in the placing pit, and the upper surface of the left-right and front-back action mechanism II is higher than the ground.

[0020] Further, the steel frame moving seat is provided with a left-right extension frame plate on the upper surface, a plurality of rollers C are arranged on the left-right extension frame plate, and rollers D are arranged on the ground. The rollers C are connected with corresponding driving mechanisms C. When the left-right and front-back action mechanism II moves to the leftmost position / rightmost position, the driving mechanisms C drive the rollers C to rotate, so that the frame for containing the filaments on the steel frame moving seat is moved to the rollers D on the ground.

[0021] Further, the steel frame moving seat and the moving plate frame are formed by welding steel pipes, so as to form a light structure.

[0022] As a preferred technical solution of the present application, the cutting mechanism I includes a first cutting blade plate and a second cutting blade plate. The first cutting blade plate and the second cutting blade plate can move towards each other and move away from each other. When they move away from each other, a spacing is formed between them, and the filaments pass through the spacing. When they move towards each other, the filaments are cut.

[0023] Further, upper surfaces of two ends of the first shear blade plate are adaptedly installed with the first slide through the first slide seat and the first slide rail; lower surfaces of two ends of the second shear blade plate are adaptedly installed with the second slide through the second slide seat and the second slide rail; the first slide seat and the second slide seat are respectively connected with the corresponding telescopic cylinder.

[0024] Further, the upper surface of the first shear blade plate is provided with a first limiting part, and the lower surface of the second shear blade plate is provided with a second limiting part; when the first shear blade plate and the second shear blade plate move towards or away from each other, the spun filaments are always located in the surrounding space formed by the first limiting part and the second limiting part.

[0025] The utility model has the following advantages:

[0026] (1) the spun filaments can be stacked in the spinning frame in a certain rule, avoiding the entanglement of the spun filaments in the spinning frame, thereby reducing the work of manually straightening the entangled spun filaments;

[0027] The conventional long spun filaments cut off are naturally stacked in the spinning frame, and when the long spun filaments are subsequently cut, the long spun filaments will be entangled in the spinning frame and need to be manually straightened;

[0028] In the present scheme, the long spun filaments are stacked in the spinning frame in a certain rule through the left-right and front-back action mechanism II, and such stacking in a certain rule makes the long spun filaments less likely to be entangled;

[0029] (2) automatic production can be realized;

[0030] The conventional long spun filaments cut off are formed into long spun filaments, and then the long spun filaments are manually loaded into the spinning frame;

[0031] In the present scheme, the movement of the spinning frame can be automatically controlled (simple PLC control), the stacking of the spun filaments in the spinning frame can also be automatically stacked (simple PLC control), the timing of cutting the spun filaments and the automatic control of allowing the end of the long spun filaments to be placed on the frame edge of the spinning frame after the spun filaments are cut off can be realized, and the present scheme is suitable for mass production.

[0041] 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.

[0042] 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, and 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 in a particular orientation and be operated, and therefore cannot be understood as limiting the utility model.

[0043] 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.

[0044] It should be noted that the molten plastic can form a single filament after passing through the corresponding filament pressing equipment, and then the filaments are subjected to silicon oil (to eliminate static electricity), and then the single filaments are bundled into a bundle, i.e. a filament bundle. Since the filaments coming out of the filament pressing equipment are continuous, it is necessary to cut the filament bundle into a long section, i.e. a long section filament bundle, and the long section filament bundle is placed in the frame for containing filaments. One frame for containing filaments contains one long section filament bundle, and the two ends of the long section filament bundle are placed on the edge of the frame for containing filaments, facilitating subsequent support work.

[0045] And the current long section of the spinning beam placed in the frame is naturally stacked; then in the subsequent work, the long section of the spinning beam needs to be straightened. Because the long section of the spinning beam is naturally stacked in the frame, the long section of the spinning beam in the frame will be entangled when it is straightened, which is difficult to straighten and needs to be straightened manually.

[0046] Therefore, the present embodiment provides a silk auxiliary structure for storing silk, as shown in Figures 1-6 As shown, it includes a silk frame 40, a cutting mechanism I, a left-right and front-back action mechanism II:

[0047] Among them, the cutting mechanism I is arranged below the existing spinning oiling and bundling equipment, the silk frame 40 is placed below the cutting mechanism I, and the silk frame 40 is connected with the left-right and front-back action mechanism II.

[0048] The spinning oiling and bundling equipment presses the spinning to be oiled and bundled (it is the prior art), and the spinning forms a spinning beam; the spinning beam falls in the silk frame 40 after the cutting mechanism I (which is not cut at this time), and the silk frame 40 is moved under the action of the left-right and front-back action mechanism II, so that the falling spinning is stacked in the silk frame 40 in a certain order; when the silk frame 40 is full of spinning beam, the cutting mechanism I cuts the spinning beam to form a long section of the spinning beam, and the two ends of the long section of the spinning beam are placed on the frame edge of the silk frame 40.

[0049] When the continuous spinning beam falls in the silk frame 40, the left-right and front-back action mechanism II: steps forward / backward, and reciprocates left and right after each step, so that the spinning beam is folded and stacked in the silk frame 40 in a certain order, so as to avoid the entanglement of the long section of the spinning beam in the silk frame 40.

[0050] Exemplarily, the corresponding principles are exemplified. For example, under the action of the left-right-forward-backward action mechanism II: (a) let the yarn containing frame 40 preliminarily locate at the front limit position, let the yarn containing frame 40 reciprocate left and right once, so that the spun yarn is folded once at the rear inner wall of the yarn containing frame 40, and then the yarn containing frame 40 reciprocates left and right for 3-5 times, so that 3-5 times of folded spun yarn appears at the rear inner wall of the yarn containing frame 40; (b) then the yarn containing frame further steps back, and then at the front-back position, reciprocate left and right for 4-6 times, so that 4-6 times of folded spun yarn appears at the front-back position; (c) then the yarn containing frame 40 further steps back once, …, so many times of stepping, until the yarn containing frame 40 steps to the front limit position, at this time, the front inner wall of the yarn containing frame also has 4-6 times of folded spun yarn; (d) when the yarn containing frame 40 steps from the front limit position to the rear limit position, a layer of 4-6 times of folded spun yarn is formed, and then the yarn containing frame 40 steps from the rear limit position to the front limit position-4-6 times of left-right reciprocation is performed every time, to form another layer of spun yarn; (e) in this way, the entire yarn containing frame 40 is filled; (f) when the yarn containing frame 40 is filled with spun yarn (through the time timer set in the control panel, the surface of the yarn containing frame is filled every fixed time, and the required time to fill can be determined by debugging, which is a very common PLC control logic, which will not be described here), when the yarn containing frame 40 reciprocates at the last step, the action amplitude is larger to the left or to the back, so that the falling spun yarn is located outside the yarn containing frame 40, and then the spun yarn is cut off by the cutting mechanism I, and the end of the cut spun yarn naturally falls off- and falls outside the yarn containing frame 40, so that the cut end of the spun yarn is placed on the frame edge of the yarn containing frame 40; (g) then the yarn containing frame 40 filled with spun yarn is removed, and a new yarn containing frame 40 is placed, when the new yarn containing frame 40 is placed, the end of the spun yarn falling from the upper silicone oil-bunching device is lower than the upper surface of the new yarn containing frame 40, so that when the new yarn containing frame 40 is pushed to the lower side of the upper silicone oil-bunching device, the end of the falling spun yarn is placed on the frame edge of the new yarn containing frame 40.

[0051] The left-right-forward-backward action mechanism II is further described below.

[0052] Reference Figures 1-3The left-right and front-back moving mechanism II includes a steel frame moving seat 21 and a moving plate frame 22. A roller A is arranged on the bottom of the moving plate frame 22, and the roller A is arranged on the front-back guide rail 23 and connected with the driving mechanism A. A left-right guide rail 24 is fixed on the upper surface of the moving plate frame 22, and the steel frame moving seat 21 is arranged on the left-right guide rail 24. A roller B is arranged on the upper surface of the steel frame moving seat 21, and the roller B is arranged on the left-right guide rail 24. A wire containing frame 40 is arranged on the upper surface of the steel frame moving seat 21. It should be noted that the driving mechanism A and the driving mechanism B are both positive and negative self-locking motors, and both are electrically connected with the control panel.

[0053] In addition, a placing pit 50 is arranged on the ground, and the front-back guide rail 23 is fixed on the bottom of the placing pit 50. The left-right and front-back moving mechanism II is arranged in the placing pit 50. Position sensors are arranged on the front wall, the rear wall, the left wall and the right wall of the placing pit 50, and the position sensors are electrically connected with the control panel. The control panel controls the left-right and front-back moving mechanism II through the position sensors (only a simple PLC control is needed, and the specific circuit connection relationship is not described here, as long as the above-mentioned empty seat can be realized).

[0054] Further, the upper surface of the left-right and front-back moving mechanism II is higher than the ground, and a roller D 51 is arranged on the ground. In addition, a left-right extension frame plate 2101 is arranged on the upper surface of the steel frame moving seat 21, and a plurality of rollers C 2102 are arranged on the left-right extension frame plate 2101. The rollers C 2102 are connected with the driving mechanism C. The wire containing frame 40 is pushed onto the rollers C 2102 through the roller D 51, and the wire containing frame 40 is displaced to the center position through the driving mechanism C (a position sensor for detecting the position of the wire containing frame 40 is arranged on the ground, and the position sensor is connected with the driving mechanism C through the control panel. The driving mechanism C is a positive and negative motor, and a pulley is arranged on the roller C 2102 and connected with the driving mechanism C through a corresponding belt). When the wire containing frame 40 is pushed, for example, when the left-right and front-back moving mechanism II moves to the left limit / right limit position, the driving mechanism C drives the roller C 2102 to rotate, so as to move the wire containing frame 40 on the steel frame moving seat 21 to the roller D 51 on the ground.

[0055] In the scheme, the steel frame moving seat 21 and the moving plate frame 22 are welded by steel pipes to form a light structure. The weight of the whole device is reduced, and the corresponding driving mechanism is prevented from being damaged (since it is a reciprocating action, such action will affect the service life of the corresponding driving mechanism. In order to increase the service life of the corresponding driving mechanism, a light structure is adopted).

[0056] The cutting mechanism I will be further described below.

[0057] Reference is made to Figures 4-6, the cutting mechanism I includes a first cutting blade plate 11 and a second cutting blade plate 12; the first cutting blade plate 11 and the second cutting blade plate 12 can move towards each other and move away from each other, when they move away from each other, a space is formed between them, and the spinning bundle passes through the space, when they move towards each other, the spinning bundle is cut off.

[0058] And, referring to Figure 5 A first sliding seat 13 is fixed on the upper surface of the two ends of the first cutting blade plate 11, the first sliding seat is in sliding fit with a first sliding rail 14, and is connected with a corresponding telescopic cylinder. A second sliding seat 15 is fixed on the lower surface of the two ends of the second cutting blade plate 12, the second sliding seat 15 is in sliding fit with a second sliding rail 16, and the second sliding seat 15 is connected with a corresponding telescopic cylinder respectively. The corresponding telescopic cylinders are also connected with a control panel, when the left-right and front-back action mechanism II reciprocates left and right within a set time, and when the reciprocation exceeds the normal reciprocation (i.e. when the reciprocation reaches the leftmost or rightmost limit position, and the spinning bundle falls outside the spinning frame 40), the first cutting blade plate 11 and the second cutting blade plate 12 move towards each other, forming two cutting clamping plates, and the spinning bundle is cut off.

[0059] And, referring to Figure 6 A first limiting part 17 is arranged on the upper surface of the first cutting blade plate 11, and a second limiting part 18 is arranged on the lower surface of the second cutting blade plate 12. The first limiting part 17 and the second limiting part 18 are in V shape, and form a prismatic space cavity, the spinning bundle falls downwards from the prismatic space cavity, and changes of the spinning bundle when falling into the spinning frame 40 are avoided.

[0060] The above embodiment only expresses a more preferred embodiment, 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 ordinary skilled persons 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.
