Description

Technical Field

[0001] The present invention relates to a relatively large range, in particular to a polyester melt spinning masterbatch hot conveying device based on intelligent adjustment suspension. Background Art

[0002] Polyester yarn is the trade name for polyester fiber. It is resistant to chemicals and frequent washing, reducing fading and discoloration.

[0003] The polyester spinning process transforms polyester chips into man-made fiber yarn through a series of processing steps. These steps involve the preparation, drying, and melting of the polyester chips, followed by the spinning, stretching, and thinning of the polyester filaments. By strictly controlling the parameters of each step, high-quality polyester yarn can be produced for a variety of applications in the textile industry.

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

[0005] The production process for polyester chips typically utilizes an intelligent overhead conveyor system, an advanced logistics solution that combines automation, the Internet of Things, and intelligent control. It primarily automates the handling, sorting, and storage of semi-finished products (such as bobbins and tows) and finished products. Its core goal is to improve production efficiency, reduce labor costs, and achieve transparency and traceability through intelligent technology.

[0006] When the actual intelligent suspension transport system is working, the continuously rotating conveyor belt or belt will vibrate. At this time, the conveyor belt drives the load to transport the load. Due to the different weights of the load, the vibration amplitude generated during operation will also be different. This vibration will lead to reduced stability during transportation, and at the same time increase the wear of the conveyor belt, resulting in structural deformation or fracture risks. Long-term operation under high amplitude conditions will shorten the equipment life and increase maintenance frequency. Summary of the Invention

[0015] The polyester melt spinning masterbatch hot conveying equipment based on intelligent adjustable suspension as described above: the moving part includes a moving disk slidably arranged in the plug-in cylinder, a threaded hole coaxially opened on the moving disk is threadedly connected to the screw rod, and a clamping block is fixedly arranged on the moving disk, and the clamping block is slidably arranged in a clamping groove opened on the inner wall of the plug-in cylinder.

When the material receiving frame slides relative to the conveyor belt, the trigger rod cooperates with the interlocking groove to drive the plug-in cylinder to move toward or away from the material receiving frame.

[0018] The polyester melt-spinning masterbatch hot conveying equipment based on intelligent adjustable suspension as described above: the engaging groove includes an inclined groove and a vertical groove provided on the guide plate.

[0019] As described above, the polyester melt spinning masterbatch hot conveying equipment based on intelligent adjustable suspension: the strain assembly includes a linkage part and a driving part, the linkage part includes a driving gear rotatably mounted on the plug-in cylinder, the driving gear is engaged with the driven gear, and a socket cylinder is sleeved on the rotating shaft of the driving gear.

[0020] As described above, the polyester melt spinning masterbatch hot conveying equipment based on intelligent adjustable suspension: the driving member includes a connecting rod slidably connected to the sleeve tube, one end of the connecting rod is fixedly provided with a tooth plate, and the other end is inserted into the mounting tube fixedly connected to the plug rod.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] By providing an elastic structure, a clamping assembly, a bidirectional movable assembly, and a strain assembly, utilizing the synergistic effect of the elastic structure and the clamping assembly, and adjusting the clamping assembly through the elastic structure composed of the plug-in rod, the fixed sleeve, and the first spring, combined with the bidirectional movable assembly and the strain assembly, the clamping force of the clamping plate can be dynamically adjusted according to the load of the material frame;

[0023] During the loading process, when the load in the material frame reaches a certain value, the material frame drops. At this time, the bidirectional moving component drives the plug-in cylinder close to the material frame to increase the clamping force of the clamping plate on the material frame, thereby preventing the material frame from shaking up and down during transportation;

[0024] As the load continues to increase, the strain assembly triggers the adjustment structure to move the movable disk in the plug-in cylinder, thereby reducing the elastic potential energy reserved by the second spring, so that the clamping force of the clamping plate is reduced accordingly, avoiding thread failure or resonance caused by overload, and ensuring stable transportation.

[0025] During the entire feeding process, the clamping assembly can adjust the elastic potential energy reserved by the second spring according to the load of the material frame to change the clamping force applied by the clamping plate to the material frame, thereby avoiding the situation where the maximum clamping force is always used to clamp the material frame during transportation, causing slight displacement between the material frame and the clamping plate, thereby causing resonance or fatigue fracture. At the same time, the amplitude of the shaking of the material frame during transportation is limited, thereby reducing wear and extending the service life of the conveyor belt and the material frame.

[0026] By utilizing the coordinated cooperation between various components, the problems of poor stability, high equipment loss, and low production efficiency caused by differences in raw materials in the transportation of traditional polyester spinning masterbatch are solved. It has both process adaptability and production economy. During the transportation process, the masterbatch can be preheated through the cooperation between the drying device and the material receiving frame, thereby shortening the time required for subsequent hot melting.

[0038] 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 accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0040] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0041] See also Figures 1-10 In an embodiment of the present invention, a polyester melt spinning masterbatch hot conveying device based on intelligent adjustable suspension includes:

[0042] A mounting frame 1, on which a conveyor belt 4 and a suction machine 2 are provided;

[0043] Specifically, see Figure 1 、 Figure 2 、 Figure 3 A 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 material placed on the conveyor belt 4 is lowered into the feeding hopper 3; then, the material falls into the suction machine 2 under the guidance of the feeding hopper 3 for subsequent processing.

[0044] The conveyor belt 4 is provided with a material receiving frame 6 at equal intervals, and the material receiving frame 6 is connected to the conveyor belt 4 through an elastic structure, and the elastic structure includes two groups of fixed sleeves 7 symmetrically fixed along the width direction of the conveyor belt 4, and the two groups of fixed sleeves 7 are provided with clamping assemblies, and the clamping assemblies are symmetrically provided with two groups along the width direction of the material receiving frame 6, and each group of the clamping assemblies includes a clamping structure and an adjusting structure, and the clamping structure is connected to the material receiving frame 6 through a bidirectional movable assembly, and the adjusting structure is connected to the elastic structure through a strain assembly;

[0045] 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.

[0046] 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.

[0047] Subsequently, the preheated masterbatch is transported by the conveyor belt 4 to the feed hopper 3, and then guided by the feed hopper 3 to the suction machine 2. After being processed by the suction machine 2, it is molten and becomes a filament through extrusion, drawing, etc. for subsequent production of polyester spinning.

[0048] 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.

[0049] In this embodiment, with the cooperation of the elastic structure, the material receiving frame 6 descends relative to the conveyor belt 4 due to the weight of the load. During the descent, the bidirectional moving component can drive the clamping structure to compress and fix the material receiving frame 6. Subsequently, as the material receiving frame 6 continues to descend, the strain component cooperates with the elastic structure to drive the adjustment structure to move, thereby adjusting the clamping force of the clamping structure on the material receiving frame 6. Through the cooperation between the clamping component and the adjustment structure, the material receiving frame 6 can be more stable during transportation by the conveyor belt 4, thereby avoiding the material receiving frame 6 from shaking in the vertical direction during transportation.

[0050] Specifically, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 The elastic structure includes a plug-in rod 12 fixedly connected to the material receiving frame 6, and two groups of the plug-in rods 12 are symmetrically arranged along the length direction of the material receiving frame 6. The two groups of plug-in rods 12 are respectively slidably arranged in the fixed sleeve 7. A first spring 10 is also slidably arranged in the fixed sleeve 7. One end of the first spring 10 abuts against the bottom of the fixed sleeve 7, and the other end abuts against the plug-in rod 12;

[0051] In particular, the above-mentioned first spring 10 is always in a compressed state, pushing the material frame 6 away from the conveyor belt 4. After the masterbatch is loaded into the material frame 6, the material frame 6 will sink a certain distance according to the weight of the masterbatch, further squeezing the first spring 10. During this process, the drying device will perform synchronous action with the material frame 6 to maintain the distance between the drying device and the material frame 6 at an appropriate distance (the appropriate distance between the material frame 6 and the drying device is reasonably adjusted in advance according to the properties of the selected masterbatch by intelligent or manual adjustment before the conveyor belt 4 runs), so as to facilitate the drying device to preheat the masterbatch in the material frame 6.

[0052] However, the elastic potential energy of the compression reserve of the first spring 10 is closely related to the weight of the masterbatch in the material receiving frame 6: the heavier the masterbatch, the more the first spring 10 is compressed, and the smaller the amplitude of the shaking during transportation; conversely, the smaller the weight of the masterbatch, the smaller the compression of the first spring 10, and the larger the amplitude of the shaking during transportation.

[0053] In this embodiment, when the conveyor belt 4 transports the material receiving frame 6 containing the masterbatch, the clamping assembly arranged on the fixed sleeve 7 can adaptively adjust the clamping force of the material receiving frame 6 according to the weight of the load in the material receiving frame 6, thereby limiting the vibration of the conveyor belt 4 during operation, causing the first spring 10 to change its reserved elastic potential energy and causing the material receiving frame 6 to vibrate in the vertical direction, thereby reducing the wear of the conveyor belt 4 during transportation, thereby improving the stability and service life of the conveyor belt 4.

[0054] Specifically, as the weight of the load in the material frame 6 increases, the elastic potential energy of the compression reserve 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 frame 6 will be relatively reduced; correspondingly, the clamping and pressing force of the clamping component on the material frame 6 will be relatively reduced. Combined with the clamping cooperation of the first spring 10 and the clamping component on the material frame 6, the degree of shaking of the material frame 6 during transportation can be further reduced, thereby improving the stability of transportation.

[0055] For details, see 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, and two groups of sliding rods 24 are provided along the width direction of the material receiving frame 6, and an inserting tube 8 is slidably provided on each group of sliding rods 24, and a second spring 20 is slidably provided in the inserting tube 8, and one end of the second spring 20 toward the material receiving frame 6 abuts against a moving rod 1501 slidably provided in the inserting tube 8, and the other end abuts against the adjusting structure, and a clamping plate 15 is fixedly provided on one end of the moving rod 1501 toward the material receiving frame 6;

[0056] Specifically, the plug-in cylinder 8 is slidably connected to the slide rod 24 via the sliding sleeve 23. Figure 9 As shown, under the cooperation of the sliding sleeve 23 and the sliding rod 24, the height between the plug-in 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.

[0057] A slider is fixedly provided on the above-mentioned moving rod 1501, and the slider is slidably set in a sliding groove opened on the inner wall of the plug-in tube 8. Under the cooperation of the slider and the sliding groove, the moving rod 1501 can only slide along the axial direction of the plug-in tube 8.

[0058] In particular, 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, and 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 between the clamping plate 15 and the material receiving frame 6, thereby further restricting the material receiving frame 6 to avoid shaking during transportation.

[0059] For further information, see Figure 8 The adjustment structure includes a screw rod 21 coaxially rotatably mounted on the plug-in cylinder 8, a moving member threadedly connected to the screw rod 21 is provided, the moving member is placed in the plug-in cylinder 8 and abuts against the second spring 20, and a driven gear 14 is coaxially fixed on the end of the screw rod 21 away from the second spring 20;

[0060] The moving part includes a moving disk 22 that is slidably arranged in the plug-in tube 8, and a threaded hole that is threadedly connected to the screw rod 21 is coaxially opened on the moving disk 22, and a clamping block 2201 is fixedly arranged on the moving disk 22. The clamping block 2201 is slidably arranged in the clamping groove 801 opened on the inner wall of the plug-in tube 8. Under 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 plug-in tube 8.

[0061] Specifically, in the initial state (the material frame 6 is in an unloaded state), the moving disk 22 approaches the clamping plate 15, and the clamping plate 15 is fitted with the material frame 6 under the push of the second spring 20; when a certain weight of masterbatch is loaded in the material frame 6 and the first spring 10 is pressed downward, the bidirectional moving component is actuated to drive the two sets of plug-in cylinders 8 to approach each other. In this process, the reaction force of the material 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 frame 6 is increased; at the same time, the strain component drives the adjusting structure to act, so that the screw rod 21 drives the moving disk 22 gradually away from the material frame 6; in this process, the moving rod 1501 The change in the distance between the second spring 20 and the movable 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 of the material frame 6 according to the sinking degree of the material frame 6, thereby avoiding the disadvantages of always using the maximum clamping force to clamp the material frame 6 (the conveyor belt 4 will vibrate during operation. During the vibration process, excessive static clamping force will cause a small displacement between the material frame 6 and the clamping plate 15, causing resonance or fatigue fracture; and excessive clamping will cause the threaded connection between the screw rod 21 and the threaded hole to fail, thereby reducing the adjustment range of the second spring 20 and reducing the reliability of the clamping plate 15).

[0062] For details, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 The bidirectional moving assembly includes a trigger structure and a guide structure. The trigger structure includes a mounting cylinder 11 fixedly connected to the plug rod 12. The mounting cylinder 11 is fixedly provided with a trigger rod 9.

[0063] Specifically, the above-mentioned installation tube 11 is placed in the through groove 701 opened on the fixed sleeve 7. During the sinking process of the material frame 6, the installation tube 11 drives the trigger rod 9 to slide along the through groove 701. At the same time, the trigger rod 9 cooperates with the guide structure to force the two groups of plug-in tubes 8 to approach the material frame 6, thereby increasing the clamping force of the clamping plate 15 on the material frame 6, and avoiding the material frame 6 from shaking up and down during transportation by the conveyor belt 4.

[0064] For details, see Figure 8 The guide structure includes a guide plate 16 fixedly arranged on the plug-in tube 8, and an interlocking groove is provided on the guide plate 16. The trigger rod 9 is slidably arranged in the interlocking groove. When the material receiving frame 6 slides relative to the conveyor belt 4, the trigger rod 9 cooperates with the interlocking groove to drive the plug-in tube 8 to move toward or away from the material receiving frame 6;

[0065] The fitting groove includes an oblique groove 1601 and a vertical groove 1602 formed on the guide plate 16;

[0066] In combination with the above, in the initial state, the trigger rod 9 is located at the head end of the stroke of the inclined groove 1601. When the weight of the masterbatch in the material frame 6 reaches a certain value (the minimum load weight of the material frame 6), the first spring 10 is squeezed downward, and the trigger rod 9 drops and cooperates with the inclined groove 1601, which can drive the two groups of plug-in tubes 8 to approach each other until the trigger rod 9 is combined with the vertical groove 1602, and the movement distance of the plug-in tube 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 frame 6 reaches the maximum; subsequently, during the process of increasing the weight of the masterbatch, the trigger rod 9 slides along the vertical groove 1602. At this time, the position of the plug-in tube 8 remains unchanged, the strain assembly acts, driving the driven gear 14 to rotate, and then controlling the screw rod 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 frame 6 increases, so that the clamping plate 15 can clamp the material frame 6 stably with a clamping force of appropriate size.

[0067] For details, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 The strain assembly includes a linkage member and a driving member. The linkage member includes a driving gear 13 rotatably mounted on the plug-in cylinder 8. The driving gear 13 is engaged with the driven gear 14, and a sleeve 18 is sleeved on the rotating shaft of the driving gear 13.

[0068] In particular, the radius of the driving gear 13 is multiple times the radius of the driven gear 14. During one rotation of the driving gear 13, the driving gear 13 can drive the driven gear 14 to rotate multiple times, so that the screw rod 21 can drive the movable disk 22 to slide along the axial direction of the plug-in cylinder 8.

[0069] The driving member includes a connecting rod 19 slidably connected to the sleeve tube 18, one end of the connecting rod 19 is fixedly provided with a tooth plate 17, and the other end is inserted into the installation tube 11 fixedly connected to the plug rod 12;

[0070] In detail, the connecting rod 19 is slidably disposed in the socket cylinder 18 that is sleeved with 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 synchronously with the plug-in cylinder 8 relative to the mounting cylinder 11 .

[0071] When the trigger rod 9 contacts the vertical slot 1602, the tooth plate 17 and the driving gear 13 enter into a meshing transmission state, and then, as the material frame 6 descends, the tooth plate 17 drives the driving gear 13 to rotate; then, the driving gear 13 and the driven gear 14 enter into a meshing transmission state, which can drive the screw rod 21 to rotate, and then drive the movable disk 22 to gradually move away from the clamping plate 15, thereby releasing the elastic potential energy stored in the second spring 20, so that the clamping plate 15 applies a suitable clamping force to the material frame 6; and as the material frame 6 descends, the clamping force of the clamping plate 15 on the material frame 6 becomes smaller, and combined with the self-gravity of the material frame 6, the conveyor belt 4 can always maintain a stable state during operation, thereby reducing the degree of shaking of the material frame 6, thereby improving the transportation stability and service life of the conveyor belt 4.

[0072] When the material receiving frame 6 is transported to the top of the feeding hopper 3, the material receiving frame 6 is turned over and the masterbatch is poured into the feeding hopper 3. At this time, the material receiving frame 6 is hung on the conveyor belt 4 with its opening facing downward until the material receiving frame 6 is opened upward. The loading and unloading process is continued, and the preheated masterbatch can be transported to the feeding hopper 3 in sequence for subsequent processing by the suction machine 2.
