Description

Technical Field

[0001] The present invention relates to a relatively large scope, specifically, a hot-state conveying device for polyester melt spinning masterbatch based on intelligent adjustable suspension. Background Art

[0002] Polyester filament is the trade name of polyester fiber. It has the characteristics of being resistant to chemical substances and frequent washing, reducing the phenomenon of clothing fading and decolorization, etc.

[0003] The polyester spinning process is a process of processing polyester chips through a series of processes and finally turning them into artificial fiber yarns, involving the preparation, drying, and melting of polyester chips, and the spinning, stretching, and thinning of polyester filaments. By strictly controlling the parameters of each link, high-quality polyester yarns can be obtained for various uses in the textile industry.

[0004] Among them, polyester chips are made from polyester polymers through extrusion and drawing methods, and its production process is mainly divided into the following steps: polymer material preparation, polymerization reaction, polymer melting, and chip shaping.

[0005] During the above-mentioned polyester chip production process, an intelligent suspension conveying system is generally used. It is an advanced logistics solution that combines automation, the Internet of Things, and intelligent control, mainly used for the automated handling, sorting, and storage of semi-finished products (such as cakes, tows) or finished products. Its core goal is to improve production efficiency, reduce labor costs, and achieve transparency and traceability in the production process through intelligent technologies.

[0006] During the actual operation of the intelligent suspension transportation system, the continuously rotating conveyor belt or belt will vibrate. At this time, when the conveyor belt drives the loading member to carry the load, due to the different weights of the loads, the vibration amplitude generated during the operation will also be different; this vibration will reduce the stability during transportation, and at the same time increase the wear of the conveyor belt, leading to risks of structural deformation or fracture. Operating at a high amplitude for a long time will shorten the equipment life and increase the maintenance frequency. Summary of the Invention

[0007] The purpose of the present invention is to provide a hot-state conveying device for polyester melt spinning masterbatch based on intelligent adjustable suspension to solve the problems raised in the above background art.

[0008] To achieve the above purpose, the present invention provides the following technical solutions: A hot-state conveying device for polyester melt spinning masterbatch based on intelligent adjustable suspension, comprising: a mounting frame, on which a conveyor belt and a material suction machine are arranged; The material receiving frames are arranged at equal intervals on the conveyor belt. The material receiving frames are connected to the conveyor belt through an elastic structure. The elastic structure includes two groups of fixed sleeves symmetrically and fixedly arranged along the width direction of the conveyor belt. Clamping components are arranged on both groups of fixed sleeves. Two groups of clamping components are symmetrically arranged along the width direction of the material receiving frame. Each group of clamping components includes a pressing structure and an adjusting structure. The pressing structure is connected to the material receiving frame through a bidirectional moving component, and the adjusting structure is connected to the elastic structure through a strain component; Under the cooperation of the elastic structure, the material receiving frame descends relative to the conveyor belt due to the weight of the loaded object. During the descending process, the bidirectional moving component can drive the pressing structure to press and fix the material receiving frame. Subsequently, along with the continuous descending of the material receiving frame, the strain component cooperates with the elastic structure to drive the adjusting structure to act, so as to adjust the pressing and clamping force of the pressing structure on the material receiving frame.

[0009] The polyester melt spinning masterbatch hot-state conveying device based on intelligent adjustable suspension as described above: The elastic structure includes inserting rods fixedly connected to the material receiving frame. Two groups of inserting rods are symmetrically arranged along the length direction of the material receiving frame. The two groups of inserting rods are respectively slidably arranged in the fixed sleeves. A first spring is also slidably arranged in the fixed sleeves. One end of the first spring abuts against the bottom of the fixed sleeve, and the other end abuts against the inserting rod.

[0010] The polyester melt spinning masterbatch hot-state conveying device based on intelligent adjustable suspension as described above: The pressing structure includes sliding rods fixedly connected to the fixed sleeves. Two groups of sliding rods are arranged along the width direction of the material receiving frame. Plug-in cylinders are slidably arranged on each group of sliding rods. A second spring is slidably arranged in the plug-in cylinders. One end of the second spring facing the material receiving frame abuts against a moving rod slidably arranged in the plug-in cylinder, and the other end abuts against the adjusting structure. And a clamping plate is fixedly arranged at one end of the moving rod facing the material receiving frame.

[0011] The polyester melt spinning masterbatch hot-state conveying device based on intelligent adjustable suspension as described above: The adjusting structure includes a lead screw coaxially and rotatably installed on the plug-in cylinder. A moving part threadedly connected to the lead screw is arranged on the lead screw. The moving part is placed in the plug-in cylinder and abuts against the second spring. And a driven gear is coaxially and fixedly arranged at one end of the lead screw away from the second spring.

[0012] The hot-state conveying equipment for polyester melt spinning masterbatch based on intelligent adjustable suspension as described above: The moving part includes a moving disk slidably arranged in the insertion cylinder. A threaded hole threadedly connected to the lead screw is coaxially formed on the moving disk, and a clamping block is fixedly arranged on the moving disk. The clamping block is slidably arranged in a clamping groove formed on the inner wall of the insertion cylinder.

[0013] The hot-state conveying equipment for polyester melt spinning masterbatch based on intelligent adjustable suspension as described above: The bidirectional moving assembly includes a triggering structure and a guiding structure. The triggering structure includes a mounting cylinder fixedly connected to the insertion rod, and a triggering rod is fixedly arranged on the mounting cylinder.

[0014] The hot-state conveying equipment for polyester melt spinning masterbatch based on intelligent adjustable suspension as described above: The guiding structure includes a guiding plate fixedly arranged on the insertion cylinder. A fitting groove is formed on the guiding plate, and the triggering rod is slidably arranged in the fitting groove. When the material receiving frame slides relative to the conveyor belt, the triggering rod cooperates with the fitting groove to drive the insertion cylinder to move towards or away from the material receiving frame.

[0015] The hot-state conveying equipment for polyester melt spinning masterbatch based on intelligent adjustable suspension as described above: The fitting groove includes an inclined groove and a vertical groove formed on the guiding plate.

[0016] The hot-state conveying equipment for polyester melt spinning masterbatch based on intelligent adjustable suspension as described above: The strain assembly includes a linkage part and a driving part. The linkage part includes a driving gear rotatably mounted on the insertion cylinder. The driving gear meshes with the driven gear, and a socket cylinder is sleeved on the rotating shaft of the driving gear.

[0017] The hot-state conveying equipment for polyester melt spinning masterbatch based on intelligent adjustable suspension as described above: The driving part includes a connecting rod slidably connected to the socket cylinder. One end of the connecting rod is fixedly provided with a toothed plate, and the other end is inserted into a mounting cylinder fixedly connected to the insertion rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are: By setting an elastic structure, a clamping assembly, a bidirectional moving assembly and a strain assembly, and utilizing the synergistic effect of the elastic structure and the clamping assembly, through the elastic structure composed of an insertion rod, a fixed sleeve and a first spring, combined with the adjustment of the clamping assembly by the bidirectional moving assembly and the strain assembly, the clamping force of the clamping plate can be dynamically adjusted according to the load of the material receiving frame; During the loading process, after the load in the material receiving frame reaches a certain value, the material receiving frame descends. At this time, the bidirectional moving assembly drives the insertion cylinder to approach the material receiving frame to increase the clamping force of the clamping plate on the material receiving frame, thereby preventing the material receiving frame from jittering up and down during transportation; As the load capacity continues to increase, the strain component triggers the adjustment structure to act, causing the moving disk in the plug-in cylinder to move, thereby reducing the elastic potential energy stored in the second spring, so that the clamping force of the clamping plate is correspondingly reduced, avoiding thread failure or resonance caused by overload, and ensuring stable transportation.

[0019] During the entire feeding process, the clamping component can adjust the elastic potential energy stored in the second spring according to the load of the material receiving frame to change the clamping force exerted by the clamping plate on the material receiving frame. When clamping the material receiving frame with the maximum clamping force all the time during transportation, it can avoid the generation of micro-displacements between the material receiving frame and the clamping plate, which may cause resonance or fatigue fracture. At the same time, it limits the amplitude of the vibration of the material receiving frame during transportation, thereby reducing wear and extending the service life of the conveyor belt and the material receiving frame.

[0020] By utilizing the coordinated cooperation among the components, it solves the problems of poor stability, high equipment loss, and low production efficiency caused by raw material differences in the transportation of traditional polyester spinning masterbatch. It has both process adaptability and production economy. During transportation, through the cooperation between the drying device and the material receiving frame, the masterbatch can be preheated, thus shortening the time required for subsequent hot melting.

Detailed implementation manners

[0032] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0033] The special word "exemplary" here means "serving as an example, embodiment or illustration". Any embodiment described as "exemplary" here does not necessarily have to be construed as superior to or better than other embodiments.

[0034] In addition, for better illustration of the present application, numerous specific details are given in the following detailed embodiments. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, methods, means, and elements well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0035] Please refer to Figures 1-10 , in the embodiment of the present invention, a hot-state conveying equipment for polyester melt spinning masterbatch based on intelligent adjustable suspension includes: Mounting frame 1, on which a conveyor belt 4 and a suction machine 2 are arranged; Specifically, please refer to Figure 1 , Figure 2 , Figure 3A supporting plate 5 is also fixedly provided on the above-mentioned mounting frame 1. The supporting plate 5 is placed under the conveyor belt 4 to support the conveyor belt 4 so that the conveyor belt 4 carrying goods can maintain a horizontal state for transporting goods; and a feeding hopper 3 fixed to the mounting frame 1 is provided between the suction machine 2 and the conveyor belt 4. During the continuous transportation of the conveyor belt 4, the materials placed on the conveyor belt 4 are lowered into the feeding hopper 3; then, the materials fall into the suction machine 2 under the guidance of the feeding hopper 3 for subsequent processing.

[0036] The conveyor belt 4 is provided with material receiving frames 6 at equal intervals, and the material receiving frames 6 are connected to the conveyor belt 4 through an elastic structure, and the elastic structure includes two groups of fixed sleeves 7 symmetrically fixedly arranged along the width direction of the conveyor belt 4, and the two groups of fixed sleeves 7 are provided with clamping components, and the clamping components are symmetrically arranged in two groups along the width direction of the material receiving frame 6, and each group of the clamping components includes a clamping structure and an adjusting structure, and the clamping structure is connected to the material receiving frame 6 through a bidirectional moving component, and the adjusting structure is connected to the elastic structure through a strain component; In detail, the material receiving frame 6 is loaded with polyester spinning masterbatches, which are usually made of high-quality polyester raw materials and are loaded into the material receiving frame 6 after being dried, filtered, and processed.

[0037] It should be noted that a drying device (not shown in the figure) is also installed on the support plate 5. During the transportation of the conveyor belt 4, the drying device can preheat the masterbatch in the material receiving frame 6. Through preheating, the masterbatch can reach the required processing temperature more quickly, thereby reducing the subsequent hot melting time and improving production efficiency.

[0038] Subsequently, the preheated masterbatch is transported by the conveyor belt 4 and placed in the feed hopper 3, and then guided by the feed hopper 3 to the suction machine 2, processed by the suction machine 2 to be in a molten state, and made into a filament by extrusion, drawing, etc., for subsequent polyester spinning.

[0039] However, in actual polyester spinning processing, there are many types of polyester raw materials to choose from, and there are large differences in the volume and weight of different types of polyester raw materials; therefore, when using the material receiving frame 6 to transport polyester raw materials of different properties, under the same volume, the weight of polyester raw materials of different properties will also be different.

[0040] In this embodiment, under the cooperation of the elastic structure, due to the load weight, the material bearing frame 6 descends relative to the conveyor belt 4. During the descending process, the bidirectional moving assembly can drive the pressing structure to press and fix the material bearing frame 6. Subsequently, as the material bearing frame 6 continues to descend, the strain assembly cooperates with the elastic structure to drive the adjusting structure to act, thereby adjusting the pressing and clamping force of the pressing structure on the material bearing frame 6. Through the cooperation between the clamping assembly and the adjusting structure, the stability of the material bearing frame 6 can be relatively strong during the transportation of the conveyor belt 4, thus avoiding the vertical jitter of the material bearing frame 6 during transportation.

[0041] Specifically, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , the elastic structure includes inserting rods 12 fixedly connected to the material bearing frame 6. Two groups of inserting rods 12 are symmetrically arranged along the length direction of the material bearing frame 6. The two groups of inserting rods 12 are respectively slidably arranged in the fixed sleeves 7. A first spring 10 is also slidably arranged in the fixed sleeves 7. One end of the first spring 10 abuts against the bottom of the fixed sleeve 7, and the other end abuts against the inserting rod 12. Particularly, the above-mentioned first spring 10 is always in a compressed state, pushing the material bearing frame 6 away from the conveyor belt 4. After the masterbatch is loaded into the material bearing frame 6, according to the weight of the masterbatch, the material bearing frame 6 will sink a certain distance, further squeezing the first spring 10. During this process, the drying device will move synchronously with the material bearing frame 6 to maintain an appropriate distance between the drying device and the material bearing frame 6 (the appropriate distance between the material bearing frame 6 and the drying device is reasonably adjusted in advance by intelligent or manual adjustment according to the properties of the selected masterbatch before the conveyor belt 4 runs), so as to facilitate the drying device to preheat the masterbatch in the material bearing frame 6.

[0042] However, the elastic potential energy stored in the compression of the first spring 10 is greatly related to the weight of the masterbatch in the material bearing frame 6: the greater the weight of the masterbatch, the greater the degree of compression of the first spring 10, and the smaller the amplitude of jitter during transportation; on the contrary, the smaller the weight of the masterbatch, the smaller the degree of compression of the first spring 10, and the greater the amplitude of jitter during transportation.

[0043] In this embodiment, when the conveyor belt 4 transports the material receiving frame 6 filled with masterbatch, the clamping assembly arranged on the fixed sleeve 7 can adaptively adjust the clamping force on the material receiving frame 6 according to the load weight in the material receiving frame 6, so as to limit the situation that the first spring 10 stores elastic potential energy due to the vibration generated during the operation of the conveyor belt 4, resulting in the material receiving frame 6 vibrating in the vertical direction, thereby reducing the wear during the transportation of the conveyor belt 4, and improving the stability and service life of the conveyor belt 4.

[0044] Specifically, as the load weight in the material receiving frame 6 increases, the elastic potential energy stored by the compression of the first spring 10 will gradually increase. At this time, during the transportation of the conveyor belt 4, the amplitude of the up-and-down shaking of the material receiving frame 6 will relatively decrease; correspondingly, the clamping and pressing force of the clamping assembly on the material receiving frame 6 will relatively decrease. Combining the clamping cooperation of the first spring 10 and the clamping assembly on the material receiving frame 6, the shaking degree of the material receiving frame 6 during transportation can be further reduced, thereby improving the stability of transportation.

[0045] Specifically, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 The pressing structure includes a sliding rod 24 fixedly connected to the fixed sleeve 7. There are two groups of the sliding rods 24 arranged along the width direction of the material receiving frame 6. A plugging cylinder 8 is slidably arranged on each group of the sliding rods 24. A second spring 20 is slidably arranged in the plugging cylinder 8. One end of the second spring 20 facing the material receiving frame 6 abuts against a moving rod 1501 slidably arranged in the plugging cylinder 8, and the other end abuts against the adjusting structure. And a clamping plate 15 is fixedly arranged at one end of the moving rod 1501 facing the material receiving frame 6. Specifically, the above plugging cylinder 8 is slidably connected to the sliding rod 24 through a sliding sleeve 23. As shown in Figure 9 , with the cooperation of the sliding sleeve 23 and the sliding rod 24, the height between the plugging cylinder 8 and the conveyor belt 4 is constant, and it can only slide along the axial direction of the sliding rod 24, that is, the width direction of the material receiving frame 6.

[0046] A slider is fixedly arranged on the above moving rod 1501. The slider is slidably arranged in a chute opened on the inner wall of the plugging cylinder 8. With the cooperation of the slider and the chute, the moving rod 1501 can only slide along the axial direction of the plugging cylinder 8.

[0047] Specifically, the above-mentioned second spring 20 is always in a compressed state, pushing the moving rod 1501 and the clamping plate 15 to have a tendency to approach the material receiving frame 6. A rubber pad is provided on the side of the clamping plate 15 away from the moving rod 1501. The rubber pad can increase the friction force between the clamping plate 15 and the material receiving frame 6, thereby further restricting the material receiving frame 6 and preventing it from shaking during transportation.

[0048] Furthermore, please refer to Figure 8 , the adjusting structure includes a lead screw 21 coaxially and rotatably installed on the insertion cylinder 8. A moving member is provided on the lead screw 21 and is threadedly connected thereto. The moving member is placed inside the insertion cylinder 8 and abuts against the second spring 20. One end of the lead screw 21 away from the second spring 20 is coaxially and fixedly provided with a driven gear 14; The moving member includes a moving disk 22 slidably arranged inside the insertion cylinder 8. A threaded hole threadedly connected to the lead screw 21 is coaxially opened on the moving disk 22. A clamping block 2201 is fixedly arranged on the moving disk 22. The clamping block 2201 is slidably arranged in a clamping groove 801 opened on the inner wall of the insertion cylinder 8. With the cooperation of the clamping block 2201 and the clamping groove 801, the moving disk 22 can only move along the axial direction of the insertion cylinder 8.

[0049] Specifically, in the initial state (when the material receiving frame 6 is in a state without load), the moving disk 22 is close to the clamping plate 15, and the clamping plate 15 is in contact with the material receiving frame 6 under the push of the second spring 20; when a certain weight of masterbatch is loaded in the material receiving frame 6 and the first spring 10 is compressed downward, the bidirectional moving assembly acts to drive the two insertion cylinders 8 to approach each other. During this process, the reaction force of the material receiving frame 6 on the clamping plate 15 can force the second spring 20 to be further compressed, so that the clamping force of the clamping plate 15 on the material receiving frame 6 increases; at the same time, the strain assembly drives the adjusting structure to act, so that the lead screw 21 drives the moving disk 22 to gradually move away from the material receiving frame 6; during this process, the change in the distance between the moving rod 1501 and the moving disk 22 causes the elastic potential energy stored in the second spring 20 to change, so that the clamping plate 15 can adaptively adjust the clamping force on the material receiving frame 6 according to the sinking degree of the material receiving frame 6, thereby avoiding the disadvantages brought about by always clamping the material receiving frame 6 with the maximum clamping force (vibrations will occur during the operation of the conveyor belt 4. During the vibration process, excessive static clamping force will cause a small displacement between the material receiving frame 6 and the clamping plate 15, resulting in resonance or fatigue fracture; and over-clamping will cause the threaded connection between the lead screw 21 and the threaded hole to fail, thereby reducing the adjustment range of the second spring 20 and the reliability of the clamping plate 15).

[0050] In detail, please refer to Figure 1 , Figure 2 , Figure 3 ,Figure 4 , Figure 6 , Figure 7 , Figure 9 , Figure 10 , the bi-directional moving component includes a triggering structure and a guiding structure. The triggering structure includes an installation cylinder 11 fixedly connected to the plugging rod 12, and a triggering rod 9 is fixedly arranged on the installation cylinder 11; Specifically, the above installation cylinder 11 is placed in a through groove 701 opened on a fixed sleeve 7. During the sinking process of the material receiving frame 6, the installation cylinder 11 drives the triggering rod 9 to slide along the through groove 701. At the same time, the triggering rod 9 cooperates with the guiding structure, and can force the two plugging cylinders 8 to approach the material receiving frame 6, so as to increase the clamping force of the clamping plate 15 on the material receiving frame 6, and avoid the up-and-down shaking of the material receiving frame 6 during the transportation of the conveyor belt 4.

[0051] In detail, please refer to Figure 8 , the guiding structure includes a guiding plate 16 fixedly arranged on the plugging cylinder 8. A fitting groove is opened on the guiding plate 16, and the triggering rod 9 is slidably arranged in the fitting groove. When the material receiving frame 6 slides relative to the conveyor belt 4, the triggering rod 9 cooperates with the fitting groove, and can drive the plugging cylinder 8 to move towards or away from the material receiving frame 6; The fitting groove includes an inclined groove 1601 and a vertical groove 1602 opened on the guiding plate 16; Combined with the above, in the initial state, the triggering rod 9 is located at the starting end of the stroke of the inclined groove 1601. When the weight of the masterbatch in the material receiving frame 6 reaches a certain value (the minimum load weight of the material receiving frame 6) and presses the first spring 10 downward, the triggering rod 9 descends and cooperates with the inclined groove 1601, and can drive the two plugging cylinders 8 to approach each other. Until the triggering rod 9 is combined with the vertical groove 1602, the moving distance of the plugging cylinder 8 reaches the maximum. At this time, the compression amount of the first spring 10 reaches the maximum, and the clamping force of the clamping plate 15 on the material receiving frame 6 reaches the maximum; subsequently, during the process of the increase of the masterbatch weight, the triggering rod 9 slides along the vertical groove 1602. At this time, the position of the plugging cylinder 8 remains unchanged, and the strain component acts to drive the driven gear 14 to rotate, and then control the lead screw 21 to drive the moving disk 22 to gradually move away from the clamping plate 15, so that the clamping force of the clamping plate 15 decreases as the weight of the material receiving frame 6 increases, so that the clamping plate 15 clamps the material receiving frame 6 with an appropriate clamping force to be stable.

[0052] In detail, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9, the strain component includes a linkage and a driving member. The linkage includes a driving gear 13 rotatably mounted on the insertion cylinder 8. The driving gear 13 meshes with the driven gear 14, and a socket cylinder 18 is sleeved on the rotating shaft of the driving gear 13; Specifically, the radius of the driving gear 13 is multiple times that of the driven gear 14. During the process of the driving gear 13 rotating one week, the driving gear 13 can drive the driven gear 14 to rotate multiple times, so that the lead screw 21 can drive the moving disk 22 to slide along the axial direction of the insertion cylinder 8.

[0053] The driving member includes a connecting rod 19 slidably connected to the socket cylinder 18. One end of the connecting rod 19 is fixedly provided with a toothed plate 17, and the other end is inserted into the mounting cylinder 11 fixedly connected to the insertion rod 12; Specifically, the connecting rod 19 is slidably arranged in the socket cylinder 18 sleeved on the driving gear 13. At the same time, due to the cooperation between the connecting rod 19 and the mounting cylinder 11, the connecting rod 19 can slide relative to the mounting cylinder 11 synchronously with the insertion cylinder 8.

[0054] When the trigger rod 9 contacts the vertical groove 1602, the toothed plate 17 and the driving gear 13 enter the meshing transmission state. Subsequently, with the descent of the material receiving frame 6, the toothed plate 17 drives the driving gear 13 to rotate; immediately, the driving gear 13 and the driven gear 14 enter the meshing transmission state, which can drive the lead screw 21 to rotate, and then drive the moving disk 22 to gradually move away from the clamping plate 15, so as to release the elastic potential energy stored in the second spring 20, so that the clamping plate 15 exerts an appropriate clamping force on the material receiving frame 6; and with the descent of the material receiving frame 6, the clamping force of the clamping plate 15 on the material receiving frame 6 becomes smaller. Combining with the self-weight of the material receiving frame 6, during the operation of the conveyor belt 4, the material receiving frame 6 can always maintain a stable state, thereby reducing the shaking degree of the material receiving frame 6, so as to improve the transportation stability and service life of the conveyor belt 4.

[0055] When the material receiving frame 6 is transported above the feeding hopper 3, the material receiving frame 6 is turned over to pour the masterbatch into the feeding hopper 3. At this time, the material receiving frame 6 is suspended on the conveyor belt 4 with the opening facing downward until the opening of the material receiving frame 6 faces upward, and then the loading and unloading process is continued. In this way, the preheated masterbatch can be sequentially conveyed into the feeding hopper 3 for subsequent processing by the suction machine 2.
