Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of glass fiber recycling, and specifically discloses a finishing and feeding device for chopped glass fiber processing. Background Art
[0002] The chopping process of glass fiber is an important process in its recycling process. The recycled glass fiber waste is first put into a cleaning tank for cleaning, then fished out and put into a drying device to dry it. The dried glass fiber is then transferred to the feeding conveyor belt of a chopping machine, and the conveyor belt sends it to a cutting knife for single cutting, so that it is cut into chopped materials about 5-7 cm according to requirements.
[0003] The utility model patent with the application number 2023216329899 discloses a chopped glass fiber waste production line, including a cutting machine, a vibrating feeder, a first conveying device, a rotary cutter, a first vibrating screen, a second conveying device, a second vibrating screen, a third conveying device and a fourth conveying device. A vibrating feeder is arranged on one side of the cutting machine. The vibrating feeder is connected to the rotary cutter through the first conveying device. A first vibrating screen is arranged below the rotary cutter. The small particle outlet of the first vibrating screen is connected to the second vibrating screen through the second conveying device. The small particle outlet of the second vibrating screen is connected to a dryer through a fifth conveying device. The large particle outlets of the first vibrating screen and the second vibrating screen are respectively connected to the vibrating feeder through the third conveying device and the fourth conveying device. When the cutting machine in this patent is running, the vibrating feeder gradually conveys the chopped glass fiber waste to the cutting knife, and then the reciprocating up and down movement of the cutting knife realizes the cutting of the chopped glass fiber waste.
[0004] However, when the existing chopped glass fiber waste is recycled, cleaned and dried, it is all processed in packages. When the irregular chopped glass fiber waste is placed on the vibrating feeder, it is necessary to manually comb the direction of the chopped glass fiber waste so that the cutting knife is perpendicular to the waste direction. Once the feeding direction of the chopped glass fiber waste deviates or even parallels the cutting knife direction, it will cause the actual cutting length of the waste to be greater than the conveying distance, resulting in the cutting length not meeting the actual requirements. In addition, when manually sorting the chopped glass fiber waste, due to the special nature of the chopped glass fiber waste itself, it will cause skin itching of the operators, seriously threatening the physical and mental health of the operators. Therefore, in view of the technical problems existing in the feeding process of the existing chopped glass fiber processing, this application proposes a finishing and feeding device for chopped glass fiber processing, so as to replace manual feeding and laying, and at the same time complete the sorting of the waste placement direction, reduce the labor intensity of the operators, and reduce the direct contact between the operators and the chopped glass fiber waste. Summary of the Invention
[0005] The present invention aims to provide a finishing and feeding device for short-cut processing of glass fibers, so as to automatically organize the chaotic short-cut glass fiber filaments before processing, enable the glass fiber filaments to be conveyed and moved in a direction perpendicular to the cutting knife in the short-cut machine, ensure that the short-cut machine can cut the glass fiber filaments to a fixed length, and ensure the short-cut quality of the glass fibers.
[0006] The present invention is realized through the following technical solutions: A finishing and feeding device for short-cut processing of glass fibers, comprising a feeding conveyor mechanism, a fiber filament finishing mechanism, a feeding conveyor mechanism and a short-cut machine which are sequentially connected and arranged. A discharging action driving mechanism is arranged at one end of the feeding conveyor mechanism close to the fiber filament finishing mechanism; The fiber filament finishing mechanism includes two side plates arranged in alignment. Two aligned turntables are rotatably arranged between the two side plates. A plurality of hanging rods are fixedly arranged in an annular array between the two turntables. Axial insertion holes are opened at both ends of the hanging rod. Axial strip openings communicating with the axial insertion holes are opened on the hanging rod. A pressing rod is inserted into the axial insertion hole. The inner end of the pressing rod is connected through the axial strip opening to a pressing ring sleeved on the hanging rod. The outer end of the pressing rod is connected to a guide wheel. A plurality of connecting sleeves are arranged on the hanging rod between the two pressing rings. A lifting hook is rotatably connected to the connecting sleeve, and a spring is arranged between two adjacent connecting sleeves. Opposite side surfaces of the two side plates are fixedly provided with annular cylinders concentric with the turntables. A guide ring groove acting on the guide wheel is opened on the annular cylinder, and the guide ring groove is connected by an outer arc segment, an inner arc segment and a transition connecting segment; The discharging action driving mechanism includes a bracket arranged on the feeding conveyor mechanism. A rotating rod is arranged at the top of the bracket, and a rotating motor is connected to one end of the rotating rod. Rotating arms are connected to both ends of the rotating rod. A magnetic carrying rod is arranged between the ends of the two rotating arms. An electromagnet for adsorbing a row of lifting hooks above the feeding conveyor mechanism is arranged on the magnetic carrying rod.
[0007] When the finishing and feeding device for chopped glass fiber processing disclosed by the present invention is in operation, the dried and disordered glass fiber filaments are conveyed by the feeding conveying mechanism to one end of the fiber filament finishing mechanism. When the fiber filament finishing mechanism is in operation, two turntables rotate around their own central axes, so that rows of material lifting hooks are carried by the hanging rods and pass through the end of the feeding conveying mechanism from top to bottom in sequence. When the hanging rod rotates with the turntable, the guide wheels at the outer ends of the pressing rods at both ends of the hanging rod are affected by the guide ring grooves, and before the material lifting hooks pass through the feeding conveying mechanism, due to the action of the inner arc segment on the guide wheels, plus the action of the pressing ring, the connecting sleeve and the spring, a row of material lifting hooks will be equally spaced and gathered towards the middle position of the hanging rod, and in this state, the glass fiber filaments conveyed by the feeding conveying mechanism will be hooked and lifted upwards. Subsequently, the guide wheels at both ends of the hanging rod act on the outer arc segment through the transition connection section, and similarly, under the action of the pressing ring, the connecting sleeve and the spring, a row of material lifting hooks are evenly spaced along the axis direction of the hanging rod, and during the process of the material lifting hooks being spaced apart, the glass fiber filaments originally piled together can be pulled, and after being pulled, the glass fiber filaments hanging on the material lifting hooks will naturally sag and straighten at both ends, so as to sort out the originally irregular glass fiber filaments neatly.
[0008] The neatly sorted glass fiber filaments continue to rotate with the hanging rod to the upper part of the feeding conveying mechanism. At this time, the unloading action driving mechanism starts to operate. First, an electric current is passed into the electromagnet to connect the material lifting hook with the magnetic rod, and then the rotating motor is started, and under the action of the rotating rod and the swing arm, the material lifting hook synchronously rotates upwards around the hanging rod. The lower end of the glass fiber filament on the material lifting hook is supported on the left end of the upper surface of the second conveyor belt, and as it continues to rotate upwards, the glass fiber filament slips off the material lifting hook and falls on the second conveyor belt, and the glass fiber filaments falling on the second conveyor belt are in a state parallel to the feeding direction as a whole. Finally, the glass fiber filaments on the second conveyor belt are conveyed to a chopping machine for chopping processing.
[0009] As a further setting of the above solution, a central rotating shaft concentric with the ring cylinder is rotatably arranged between the two side plates. One end of the central rotating shaft is connected with a power assembly, and the two turntables are respectively arranged at both ends of the central rotating shaft. The above is one of the specific transmission methods of the fiber filament finishing mechanism. The central rotating shaft is driven to rotate by the power assembly, so as to realize the active rotation operation of the turntable, the hanging rod and the material lifting hook.
[0010] As a further setting of the above solution, the outer arc segment is arranged at one end of the annular cylinder close to the side plate, and the outer arc segment extends from above the feeding and conveying mechanism to below the feeding and conveying mechanism. The inner arc segment is arranged at one end of the annular cylinder away from the side plate, and the two ends of the outer arc segment and the inner arc segment are connected end to end by a transition connecting segment. The above is the specific position design method of the entire guiding ring groove, which can ensure that during the upward and downward cyclic conveying process of the material lifting hook, a row of material lifting hooks on the hanging rod first gather together to lift the glass fiber filaments, and then expand and arrange them. The arrangement of the expanded material lifting hooks is used to sort the glass fiber filaments, and finally the sorted glass fiber filaments are placed on the feeding and conveying mechanism for short cutting and feeding.
[0011] As a further setting of the above solution, the guiding ring groove is opened on the outer circular surface or the inner circular wall of the annular cylinder. The specific setting of the guiding ring groove on the outer circular surface or the inner circular wall of the annular cylinder is designed according to the orientation of the guiding wheel at the outer end of the pressing rod. As long as it is ensured that during the rotation and movement of the hanging rod with the turntable, the guiding wheel can always act on the guiding ring groove.
[0012] As a further setting of the above solution, the feeding and conveying mechanism includes a first conveying seat, a first conveyor belt is arranged in the first conveying seat, a feeding table is arranged at the end of the first conveying seat close to the fiber filament sorting mechanism, and a plurality of material hook through grooves arranged side by side and aligned with each material lifting hook in the gathered state are opened at the end of the feeding table.
[0013] As a further setting of the above solution, the feeding and conveying mechanism includes a second conveying seat connected to the short cutter, a second conveyor belt is arranged in the second conveying seat, and a feeding roller is arranged above the second conveyor belt on the side close to the short cutter.
[0014] The above is one of the specific design solutions of the feeding and conveying mechanism and the feeding and conveying mechanism. The directional conveying of the glass fiber filaments is realized through the belt conveying device, and by controlling the conveying speed, it is easy to control the feeding and feeding speeds.
[0015] As a further setting of the above solution, a combing mechanism for sorting the glass fiber filaments placed on the second conveyor belt is arranged above the feeding and conveying mechanism.
[0016] As a further setting of the above solution, the combing mechanism includes a gantry arranged above the second conveying seat. A lifting frame is connected in the gantry through a first air cylinder. A pressing edge strip perpendicular to the moving direction of the second conveyor belt is connected in the lifting frame through a second air cylinder. A third air cylinder is arranged at the side end of the lifting frame. A moving comb strip moving towards the short cutter is connected to the end of the third air cylinder, and a row of combing teeth is connected to the lower surface of the moving comb strip.
[0017] The present invention further arranges a combing mechanism above the second conveying seat. After the fiber filament sorting mechanism places the preliminarily sorted glass fiber filaments on the second conveyor belt, the combing mechanism can perform a further combing operation. The specific combing operation is to first press the end of the glass fiber filaments by pressing down the edge pressure strip, and then move the comb strip along the conveying direction. During the movement, the glass fiber filaments are further combed by the combing rack to ensure that the glass fiber filaments can maintain a better feeding movement perpendicular to the cutting knife. Combined with the short-cutting processing of the short-cutting machine, the glass fiber filaments can be short-cut at a fixed distance.
[0018] As a further configuration of the above scheme, a receiving plate is provided at the lower end of the fiber filament arrangement mechanism for receiving the glass fiber filaments dropped from the lifting hook, and one end of the receiving plate is tilted downward. The receiving plate is used to receive the glass fiber filaments dropped from the fiber filament arrangement mechanism, and then collect them and place them on the feeding conveying mechanism for further feeding.
[0019] Compared with the prior art, the present invention has the following beneficial effects: The arranging and feeding device for glass fiber chopped processing disclosed in the present invention can arrange the chaotic glass fiber filaments before chopped through the design of the fiber filament arranging mechanism, firstly use a row of lifting hooks gathered together to hook up the clumped glass fiber filaments, and then use the row of lifting hooks with a widened distance to pull the glass fiber filaments during the rotating conveying process, so that the two ends of the glass fiber filaments hung on the lifting hooks after pulling naturally droop and straighten, and finally unload the glass fiber filaments on the lifting hooks through the unloading action driving mechanism, so that the straightened glass fiber filaments are neatly placed on the feeding conveying mechanism, and then are transported to the chopped machine for fixed-length cutting processing; the arranging and feeding device disclosed in the present invention realizes automatic feeding and combing and arranging, and does not need manual feeding, laying and arranging, which not only reduces the labor of operators and avoids the problem of skin itching caused by contact between operators and glass fiber filaments, but also the glass fiber filaments can be effectively arranged to a vertical conveying state, thereby effectively ensuring the chopped processing quality of the glass fiber filaments.
[0020] The fiber filament sorting mechanism of the present invention has a novel and ingenious structural design, and utilizes the rotating conveying process to automatically realize the gathering and spreading of a row of material lifting hooks, and then uses the action of the material lifting hooks to sort and straighten the chaotic glass fiber filaments that were originally clumped together, thereby effectively solving the problem of glass fiber sorting and having a better sorting effect.
[0021] The present invention further provides a combing mechanism to perform secondary combing on the glass fiber filaments that have been sorted and placed on the feeding and conveying mechanism, ensuring that the glass fiber filaments can maintain a better feeding movement in a direction perpendicular to the cutting knife, and combined with the short cutting process of the short cutting machine, the consistency and quality of the products after the glass fiber filaments are cut can be ensured.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] In order to enable those skilled in the art to better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.
[0025] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will refer to the attached Figures 1 to 10 drawings and describe the present application in detail with reference to the embodiments. Embodiment 1
[0026] Example 1 discloses a finishing and feeding device for chopped glass fiber processing. Refer to the attached Figure 1 and the attached Figure 2 , which includes a base 1. A feeding conveyor mechanism 2, a fiber filament finishing mechanism 3, a feeding conveyor mechanism 4, and a chopper 5 are sequentially arranged on the upper surface of the base 1 from left to right. Among them, the feeding conveyor mechanism 2 includes a first conveyor seat 201, and a first conveyor belt 202 is arranged in the first conveyor seat 201. A feeding table 203 connected to the first conveyor belt 202 is arranged at the right end of the first conveyor seat 201, and a plurality of hook material through grooves 204 arranged side by side front and back are opened at the right end of the feeding table 203 (refer to the attached Figure 10 ).
[0027] Refer to the attached Figures 3 to 6 , the fiber filament finishing mechanism 3 includes side plates 301 that are aligned front and back and fixed on the base 1. A central rotating shaft 302 is arranged between the upper ends of the two side plates 301, and a power assembly 303 is connected to the front end of the central rotating shaft 302. Specifically, the power assembly is composed of a motor + a transmission chain or a transmission belt. A turntable 304 is fixedly connected to each of the front and rear ends of the central rotating shaft 302 between the two side plates 301. A plurality of hanging rods 305 parallel to the central rotating shaft 302 are fixedly arranged in an annular array at the outer edges of the two turntables 304. Axial insertion holes 3051 are opened at both ends of the hanging rod 305 facing the center, and axial slits 3052 communicating with the axial insertion holes 3051 are opened on the hanging rod 305. A pressing rod 306 with an outer end extending out is inserted into each axial insertion hole 3051. A guide wheel 307 is rotatably connected to the outer end of the pressing rod 306. The inner end of the pressing rod 306 is connected to a pressing ring 308 sleeved on the outer circumferential surface of the hanging rod 305 through the axial slit 3052. A plurality of connecting sleeves 309 sleeved on the outer circumferential surface of the hanging rod 305 are arranged at equal intervals between the two pressing rings 308. The outermost connecting sleeves 309 on both sides are abutted against the pressing rings 308. At the same time, a spring 310 sleeved on the outer circumferential surface of the hanging rod 305 is arranged between adjacent two connecting sleeves 309. A material lifting hook 311 is rotatably connected to each connecting sleeve 309. All the material lifting hooks 311 are vertically downward under the action of their own gravity, and the lower hook parts of the material lifting hooks 311 are arranged towards the side of the feeding conveyor mechanism 2.
[0028] In addition, the fiber strand finishing mechanism 3 further includes two annular cylinders 312 which are respectively arranged at the upper ends of the opposite sides of the two side plates 301 and are concentrically arranged with the central rotating shaft 302. A guiding ring groove 313 which interacts with all the guiding wheels 307 on the corresponding side is formed on the outer circumferential surface or the inner circumferential wall of each annular cylinder 312. The guiding ring groove 313 is composed of an outer arc segment 3131, an inner arc segment 3132 and a transition connecting segment 3133. Among them, the outer arc segment 3131 is arranged at one end of the annular cylinder 312 close to the side plate 301, and the outer arc segment 3131 starts from above the feeding conveyor mechanism 2 and extends to below the feeding conveyor mechanism 4. The inner arc segment 3132 is arranged at one end of the annular cylinder 312 far from the side plate 301 (i.e., one end close to the middle position of the central rotating shaft 302), and then the two ends of the outer arc segment 3131 and the inner arc segment 3132 are connected by the transition connecting segment 3133.
[0029] When the guiding wheels 307 on both sides interact with the inner arc segment 3132, through the action of the pressing rod 306, the pressing ring 308 and the spring 310, all the material lifting hooks 311 will be evenly closed in the middle position of the hanging rod 305, and at this time, the material lifting hooks 311 and the material hook-through grooves 204 on the feeding table 203 are aligned one by one. When the material lifting hooks 311 pass above the feeding table 203 clockwise along with the hanging rod 305, the material lifting hooks 311 can hook up all the glass fiber strands on the upper surface of the feeding table 203 through the material hook-through grooves 204. When the guiding wheels 307 on both sides interact with the outer arc segment 3131, through the action of the pressing rod 306, the pressing ring 308 and the spring 310, all the material lifting hooks 311 will be arranged in a widened distance along the axis direction of the hanging rod 305. And during the process of the widened distance arrangement of the material lifting hooks 311, the glass fiber strands that were originally piled up and hooked can be pulled. After being pulled, the glass fiber strands hanging on the material lifting hooks 311 will naturally droop and straighten at both ends, so as to sort out the originally irregular glass fiber strands.
[0030] Refer to the appendix Figure 7, the feeding and conveying mechanism 4 includes a second conveying seat 401 connected to the feeding port of the chopper 5. A second conveyor belt 402 is arranged in the second conveying seat 401, and a feeding roller 403 is arranged above the second conveyor belt 402 near the feeding port of the chopper 5. The glass fiber filaments can be fed into the chopper 5 for cutting through the interaction of the second conveyor belt 402 and the feeding roller 403. At one end of the second conveying seat 401 close to the fiber filament finishing mechanism 3, there is a discharging action driving mechanism 6 that interacts with a row of lifting hooks 311 to achieve discharging. Specifically, the discharging action driving mechanism 6 includes brackets 601 connected to the front and rear ends of the second conveying seat 401. A rotating rod 602 is connected between the tops of the two brackets 601, and a rotating motor 603 is connected to one end of the rotating rod 602. Rotating arms 604 are connected to both the front and rear ends of the rotating rod 602. A magnetic rod 605 is arranged between the ends of the two rotating arms 604. Then, an electromagnet 606 aligned with each lifting hook 311 is arranged at one end of the magnetic rod 605 facing the lifting hook 311.
[0031] When the unfolded lifting hook 311 carrying the combed glass fiber filaments rotates and moves to directly above the left end of the second conveyor belt 402, an electric current is passed into the electromagnet 606, thereby generating a magnetic suction force on the lifting hook 311 (it should be noted here that the lifting hook 311 is made of iron). Then, the rotating motor 603 is started to make the rotating rod 602 rotate counterclockwise. At this time, under the action of the magnetic suction force, the lifting hook 311 will synchronously rotate upward around the hanging rod 305. The lower end of the glass fiber filaments on the lifting hook 311 is supported on the upper surface of the left end of the second conveyor belt 402 and continues to rotate upward with it, so that the glass fiber filaments slip off the lifting hook 311 and fall on the second conveyor belt 402. At the same time, the glass fiber filaments falling on the second conveyor belt 402 are in a state parallel to the feeding and conveying direction as a whole (refer to the attached Figure 6 ), so that during the subsequent short-cutting process, it can be ensured that the glass fiber filaments are perpendicular to the cutting knife, enabling the glass fiber filaments to be neatly short-cut. Embodiment 2
[0032] Embodiment 2 discloses a finishing and feeding device for glass fiber short-cutting processing, which is further optimized and improved based on the basic solution in Embodiment 1. The same parts as in Embodiment 1 will not be described again.
[0033] Refer to the attached Figure 2 、the attached Figure 8 and the attached Figure 9, in this Embodiment 2, a carding mechanism 7 is provided above the feeding and conveying mechanism 4. The carding mechanism 7 includes a gantry 701 disposed across the upper part of the second conveying seat 401. A first cylinder 702 is provided at the upper end of the gantry 701. The lower end of the first cylinder 702 is connected to a lifting frame 703. A second cylinder 704 is provided at the upper end of the lifting frame 703. The lower end of the second cylinder 704 is provided with a bead pressing block 705 disposed perpendicular to the moving direction of the second conveyor belt 402. And a corresponding rubber anti-slip layer is provided on the lower surface of the bead pressing block 705. A third cylinder 706 is provided at the side end of the lifting frame 703. The right end of the third cylinder 706 is connected to a moving comb bar 707. And a row of carding racks 708 is connected to the lower surface of the moving comb bar 707.
[0034] Through the design of the above carding mechanism 7 in this Embodiment 2, after the glass fiber filaments on the lifting hooks 311 fall onto the second conveyor belt 402, the second conveyor belt 402 will convey them to directly below the carding mechanism 7. Then, quickly start the first cylinder 702 and the second cylinder 704, so that the bead pressing block 705 presses and fixes the left end of the glass fiber filaments. At the same time, a row of carding racks 708 extends into the glass fiber filaments on the right side of the bead pressing block 705. Then start the third cylinder 706 to make a row of carding racks 708 move to the right, and further card the glass fiber filaments on the second conveyor belt 402 to be perpendicular to the direction of the cutting knife, ensuring that the short cutter can perform fixed-length cutting processing on the glass fiber filaments.
[0035] In addition, in this Embodiment 2, a receiving plate 314 is fixed between the lower ends of the side plates 301. And the right end of the receiving plate 314 is inclined downward. At the same time, the upper surface of the receiving plate 314 is smooth, facilitating the sliding of the received glass fiber filaments. Through the above design in this Embodiment 2, during the process of the lifting hooks 311 expanding and arranging, some glass fiber filaments directly falling from the lifting hooks 311 will be received by the receiving plate 314, and then discharged from its right end for collection. After collection, they can be placed on the feeding and conveying mechanism 2 again for feeding.
[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
