Description

Technical Field

[0001] The utility model relates to the technical field of fiber processing, in particular to a pretreatment device for hollow polyester staple fibers. Background Art

[0002] Hollow polyester staple fiber is the abbreviation of chemical fiber with a cavity along the axial direction of the cross-section. It is an important profiled fiber. The hollow structure endows them with good properties of light weight and filling modification, improves the bending resistance and wear resistance of the fiber. At the same time, due to the hollow structure, it also shows good performance in sound insulation and sound absorption. When processing and producing hollow polyester staple fibers, humidification treatment needs to be carried out through a pretreatment device.

[0003] In the existing technology, the pretreatment device for hollow polyester staple fibers generally sprays water on the hollow polyester staple fibers placed on the conveyor belt through a nozzle. Due to the small and light quality of the hollow polyester staple fibers, the material may be scattered during the spraying process.

[0004] The existing patent (publication number: CN214938373U) discloses a pretreatment device for hollow polyester staple fibers. Through an electric push rod, the protective cover can be pushed to cooperate with the support plate to cover the hollow polyester staple fibers on the surface of the conveyor belt, so as to effectively prevent the hollow polyester staple fibers from rising and floating out when the nozzle sprays water for humidification.

[0005] In view of the above problems, although the solution given by the existing patent can avoid the situation of flying of hollow polyester staple fibers through the cooperation of components such as the cylinder protective cover, due to the certain impact pressure of the sprayed water, the hollow polyester staple fibers may be stressed and piled up, resulting in some parts that cannot be fully combined with the water source, affecting the treatment effect. Summary of the Invention

[0006] The purpose of the utility model is to provide a pretreatment device for hollow polyester staple fibers, which can block the circulation port to prevent the material from detaching, and press the material tightly to avoid piling up when being washed and wetted by water, resulting in some materials being overlapped and unable to fully contact the water source, leading to poor treatment effect, so as to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A pretreatment device for hollow polyester staple fibers, including a structural frame, and a processing mechanism is arranged between the two structural frames;

[0008] The processing mechanism includes a belt conveyor, which is installed at the position between two structural frames. A dust-proof box is fixed at the top of the structural frame. There are circulation openings between the two sides of the outer wall of the dust-proof box and the belt conveyor. A hydraulic rod is embedded at the top of the dust-proof box. The power output end of the hydraulic rod is connected with an adapter plate, and fixed plates are fixed at the two bottom ends of the axial direction of the adapter plate. A cover shell is connected below the fixed plate, and a metal fine mesh is embedded at the position between the two fixed plates at the top of the cover shell.

[0009] Preferably, the adapter plate is of a U-shaped structure, and the adapter plate and the dust-proof box form a sliding structure through the hydraulic rod.

[0010] Preferably, a connecting pipe penetrates into one side of the hydraulic rod at the top of the dust-proof box, and a water tank is connected to the end of the connecting pipe that penetrates into the dust-proof box.

[0011] Preferably, a sliding groove is opened above the circulation opening on one side of the outer wall of the dust-proof box, and a humidifying mechanism is arranged inside the sliding groove.

[0012] Preferably, the humidifying mechanism includes a motor. The motor is slidably connected to one side of the sliding groove, and the power output end of the motor is connected with a bidirectional threaded rod. The outer wall of the end of the bidirectional threaded rod that penetrates into the dust-proof box is slidably connected with a circulation shell, and a conveying hose penetrates out of one side of the top of the circulation shell.

[0013] Preferably, the humidifying mechanism further includes an atomizing nozzle. The atomizing nozzle is embedded on one side of the bottom end of the circulation shell, and a brush is installed on one side of the atomizing nozzle at the bottom end of the circulation shell.

[0014] Preferably, the bidirectional threaded rod is threadedly connected with the circulation shell, and the circulation shell and the bidirectional threaded rod form a sliding structure.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. The belt conveyor, the dust-proof box and the circulation openings initially play an effect of preventing materials from flying and scattering. In cooperation with the hydraulic rod, the adapter plate, the fixed plates, the cover shell and the metal fine mesh, the circulation openings can be blocked to prevent the materials from detaching, and the materials can be pressed tightly to avoid the situation of stacking when being washed and wetted by water, resulting in some stacked materials not being able to fully contact with the water source, leading to poor treatment effect.

[0017] 2. Through the cooperation of the motor, the bidirectional threaded rod, the circulation shell, the conveying hose, the atomizing nozzle and the brush, the comprehensiveness of spraying and wetting the materials can be improved, avoiding dead corners that affect the treatment effect and quality. At the same time, in cooperation with the brush fitting the metal fine mesh, it is avoided that the materials are adsorbed and difficult to detach. Description of the Drawings

[0026] The present invention provides a technical solution:

[0027] Please refer to Figures 1 to 3, a pretreatment device for hollow polyester staple fibers, comprising a structural frame 1, and a processing mechanism 2 is arranged between two structural frames 1; the processing mechanism 2 includes a belt conveyor 201, the belt conveyor 201 is installed at a position between two structural frames 1, a dust-proof box 202 is fixed at the top of the structural frame 1, a circulation port 203 is arranged between the two outer walls of the dust-proof box 202 and the belt conveyor 201, a hydraulic rod 204 is embedded at the top of the dust-proof box 202, a connecting plate 205 is connected to the power output end of the hydraulic rod 204, fixing plates 206 are fixed at the two axial bottom ends of the connecting plate 205, a cover shell 207 is connected below the fixing plates 206, a metal fine mesh 208 is embedded at the position between the two fixing plates 206 at the top of the cover shell 207, the structure of the connecting plate 205 is a U-shaped structure, and the connecting plate 205 forms a sliding structure with the dust-proof box 202 through the hydraulic rod 204. A connecting pipe 3 penetrates into one side of the hydraulic rod 204 at the top of the dust-proof box 202, and one end of the connecting pipe 3 penetrating into the dust-proof box 202 is connected to a water tank 4.

[0028] By adopting the above technical solution, while the belt conveyor 201 is fixed by the structural frame 1, it is avoided that the materials break away from both sides. The materials are transported into the dust-proof box 202 through the circulation port 203 to avoid the situation of flying when flushing with water. The hydraulic rod 204 is used to push the connecting plate 205, so that the fixing plates 206 drive the cover shell 207 to cover the materials, and the metal fine mesh 208 presses the materials tightly. The circulation port 203 is closed by the fixing plates 206, so that when flushing the materials, the situations of flying and stacking are avoided, resulting in insufficient wetness of some materials. The water source is conveniently introduced into the water tank 4 through the connecting pipe 3. The water tank 4 is embedded at the top end inside the dust-proof box 202, and a reserved hole is provided corresponding to the hydraulic rod 204.

[0029] Specifically, as Figure 2 and Figure 4 shown, a sliding groove 5 is opened above the circulation port 203 on one outer wall of the dust-proof box 202, a humidifying mechanism 6 is arranged inside the sliding groove 5, the humidifying mechanism 6 includes a motor 601, the motor 601 is slidably connected to one side of the sliding groove 5, a bidirectional threaded rod 602 is connected to the power output end of the motor 601, a circulation shell 603 is slidably connected to the outer wall of one end of the bidirectional threaded rod 602 penetrating into the dust-proof box 202, a conveying hose 604 penetrates out of one side of the top of the circulation shell 603, the humidifying mechanism 6 further includes an atomizing nozzle 605, the atomizing nozzle 605 is embedded at one side of the bottom end of the circulation shell 603, a brush 606 is installed on one side of the atomizing nozzle 605 at the bottom end of the circulation shell 603, the bidirectional threaded rod 602 is threadedly connected to the circulation shell 603, and the circulation shell 603 forms a sliding structure with the bidirectional threaded rod 602.

[0030] By adopting the above technical solution, the motor 601 installed in the fixed plate 206 slides along the sliding groove 5 under the action of the hydraulic rod 204, drives the bidirectional threaded rod 602 through the motor 601, so that the two flow-through shells 603 slide reciprocally relative to or away from each other above the metal fine mesh 208, introduce water source from the water tank 4 to the flow-through shell 603 through the pump and the delivery hose 604, and spray it out through the atomizing nozzle 605 to moisten the material. When the flow-through shell 603 slides, it drives the brush 606 to slide in contact with the metal fine mesh 208 to avoid the situation of material adhesion and adsorption and hanging.

[0031] Working principle: The structure frame 1 limits the material conveyed by the belt conveyor 201, and the material enters and exits the dust-proof box 202 through the flow-through port 203. The hydraulic rod 204 drives the connecting plate 205, so that the fixed plate 206 drives the cover shell 207 to press downwards, thereby covering the material entering the dust-proof box 202 and closing the flow-through port 203. The material is pressed by the metal fine mesh 208 to avoid material flying and avoid accumulation when impacted by water pressure. The water source is introduced from the connecting pipe 3 into the water tank 4, and through the delivery of the pump, the water source enters the flow-through shell 603 through the delivery hose 604, and then is sprayed out through the atomizing nozzle 605 to moisten the material. The motor 601 is installed on the fixed plate 206 and slides along the sliding groove 5 under the drive of the hydraulic rod 204. The motor 601 drives the bidirectional threaded rod 602, so that the two flow-through shells 603 slide reciprocally to improve the comprehensiveness of material moistening, and cooperate with the brush 606 to contact the metal fine mesh 208 to avoid material adsorption.

[0032] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
