Description

Technical Field

[0001] The present invention relates to the technical field of fiberglass filament recycling, and specifically discloses a drying device for fiberglass filament recycling and processing. Background Art

[0002] In the process of recycling and processing fiberglass filaments, the packaged recycled materials need to be put into an alkali solution tank for treatment. After the treatment, they are washed and dehydrated, and then sent to a drying device after dehydration to reduce their water content to no more than 3%. Finally, they are sent to a cutting machine for short-cut processing.

[0003] There are many types of existing drying devices for fiberglass filaments. The most common one is a dryer with a drying box + metal mesh belt structure. During its operation, the dehydrated fiberglass filaments are evenly laid on the metal mesh belt by an operator, and then the metal mesh belt transports them to the inside of the drying box to contact with the hot air flow, thereby completing the drying. For example, the utility model patent with the application number 201822240709.5 discloses a drying device for fiberglass filaments, including a feeding machine box. The two inner walls on both sides of the feeding machine box are sleeved with two horizontally arranged feeding central shafts through bearings. The circumferential outer walls of the two feeding central shafts are both sleeved with feeding conveyor rollers, and the circumferential outer walls of the two feeding conveyor rollers are sleeved with the same feeding conveyor belt. What this patent discloses is a dryer with a drying box + metal mesh belt structure. When it is used for drying and processing fiberglass filaments, although it can realize the streamlined drying treatment of fiberglass filaments, there are still some deficiencies. First, when loading the fiberglass filaments, it is necessary to lay them as evenly as possible on the feeding conveyor belt, which increases the difficulty of the loading operation. Second, the lower layer of the fiberglass filaments laid on the conveyor belt is difficult to fully contact with the hot air flow, resulting in uneven drying of the upper and lower layers of materials and the need to extend the drying time. Therefore, in view of the deficiencies of the existing belt-type drying equipment when used for drying fiberglass filaments, the present application proposes a newly designed drying device for fiberglass filament recycling and processing to solve the above technical problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a newly designed drying device for fiberglass filament recycling and processing. During operation, the fiberglass filaments are hooked up as a whole by concentrated and side-by-side hooking members, and then the hooking members are gradually unfolded, so that the fiberglass filaments are evenly unfolded and the two ends droop and spread out. Finally, they are contacted with the high-temperature air flow to complete rapid drying, realizing the rapid and uniform drying treatment of fiberglass filaments.

[0006] As a further configuration of the above solution, a rapping mechanism for rapping the glass fiber filaments suspended on the hook member is provided in the drying box.

[0007] As a further configuration of the above scheme, the beating mechanism includes a rotating rod rotatably arranged in the drying box, and a torsion spring is arranged between the rotating rod and the inner wall of the drying box, the outer end of the rotating rod is connected to a gear, a rotating motor is installed on the drying box, an incomplete gear acting on the gear is arranged on the rotating motor, and a beating rod is fixedly connected to the rotating rod through a radial connecting rod.

[0008] As a further configuration of the above scheme, the feeding unit includes a first conveying seat connected to the left end face of the drying box, a first conveying belt is arranged in the first conveying seat, a material guide table extending into the interior of the drying box is arranged at the right end of the first conveying seat, and a slit for passing each hook member is opened at the end of the material guide table.

[0009] As a further arrangement of the above scheme, the inner section starts from the lower end of the closed-loop guide plate on the right side of the discharging unit, extends to pass through the feeding unit and sets the end point on the left side of the upper end of the closed-loop guide plate. The outer section is offset relative to the inner end at other positions on the closed-loop guide plate, and the inner section and the outer section are connected by a diagonal connecting section.

[0010] As a further configuration of the above scheme, the material unloading and shifting mechanism includes a bracket fixedly connected to the inner wall of the drying box, a swing arm stopper rod is rotatably provided on the bracket, and a driving device for driving the swing arm stopper rod to rotate is provided on the bracket.

[0011] As a further setting of the above solution, the discharging unit includes a second conveying seat arranged at the bottom of the drying box and extending out of the drying box at one end, and a second conveyor belt is arranged in the second conveying seat directly below the hanging material conveying unit.

[0012] As a further setting of the above solution, the transmission mechanism includes rotating shafts arranged at the left and right ends of the drying box, and a power device is connected to the end of one of the rotating shafts. Transmission wheels are arranged at the front and rear ends of the rotating shafts. The two closed-loop conveying members are arranged between two transmission wheels aligned left and right. A plurality of connecting columns are evenly fixed on each closed-loop conveying member at equal intervals. The hollow rod is arranged on two aligned connecting columns.

[0013] As a further setting of the above solution, the hot air unit includes a hot air source. A hot air main pipe is connected to the end of the hot air source. A plurality of hot air branch pipes extending into the drying box are arranged on the hot air main pipe. A row of nozzles that are inclined upward and act on the fiberglass filaments in the upper hanging members are arranged on the hot air branch pipes.

[0014] As a further setting of the above solution, the negative pressure suction unit includes a negative pressure pipe connected to the upper end of the drying box. A filter box is connected to the end of the negative pressure pipe, and a negative pressure generator is connected to the filter box.

[0015] During the operation of the drying equipment for recycling and processing fiberglass filaments disclosed in the present invention, the first conveyor belt in the feeding unit conveys the fiberglass filaments to be dried from the outside to the internal material guiding platform, and the fiberglass filaments will accumulate above the slit opening.

[0016] Under the action of the transmission mechanism, the two closed-loop conveying members move synchronously clockwise. When a corresponding set of hanging member units moves past the position of the material guiding platform, due to the interaction between the guide wheels and the inner section of the closed-loop guide groove, a row of hanging members gather towards the middle at this time, and each hanging member is aligned vertically with the slit opening on the material guiding platform. When the hanging members pass through the slit opening from bottom to top, a row of hanging members can hook up all the fiberglass filaments accumulated on the material guiding platform and continue to convey them upward. When the guide wheels move to interact with the outer section of the closed-loop guide groove, a row of hanging members can be evenly unfolded along the axial direction of the hollow rod at this time, and the concentrated fiberglass filaments hooked up will be evenly unfolded as the hanging members move away from each other, and the two ends of the unfolded fiberglass filaments droop naturally and spread out.

[0017] Subsequently, the unfolded and drooping fiberglass filaments will continue to be conveyed to the air outlet position of the hot air unit by the hanging members. Then, the hot air flow evenly discharged from the hot air branch pipes will directly act on the fiberglass filaments, enabling them to come into full contact with the hot air flow, so as to quickly complete drying. At the same time, the wet and hot gas generated during the drying process is drawn away and filtered from the top of the drying box by the negative pressure suction unit.

[0018] Finally, the glass fiber filaments after drying will gather together again as the hook parts approach each other before unloading. Then, when they move to the position of the unloading toggle mechanism, they will be hindered by the swing arm lever, causing a row of hook parts to rotate upward. After rotating to a certain angle, the glass fiber filaments naturally slide off the hook parts and are received by the unloading unit and sent out of the drying box.

[0019] In addition, the present invention further arranges a vibrating mechanism inside the drying box. When the evenly spread out glass fiber filaments with both ends drooping are transported to the position of the vibrating mechanism along with the hook member, the rotating motor is started to allow the beating rod to rotate toward the side away from the glass fiber filaments to accumulate momentum, and then the beating rod is instantly released to allow the glass fiber filaments to be beaten. The hanging glass fiber filaments are vibrated by beating, thereby accelerating the shaking off of their own moisture. Combined with the effect of the hot air flow, the drying speed of the glass fiber filaments can be accelerated and the drying effect can be improved.

[0020] Compared with the prior art, the present invention has the following beneficial effects: The drying equipment for glass fiber recycling and processing disclosed in the present invention adopts a transmission structure of a closed-loop conveying member + a hook member, in which the closed-loop conveying member drives the hook member to move and pass through a material guide table in a feeding unit, thereby hanging up the glass fiber yarn on the material guide table. After hanging up, during the conveying process, the high-temperature hot air flow continuously discharged acts on the suspended glass fiber yarn, thereby enabling the high-temperature air flow and the glass fiber yarn to have a larger heat exchange area, thereby shortening the drying time of the glass fiber yarn and improving the drying efficiency.

[0021] During the conveying process, the hook members in the present invention can centrally hook a row of hook members when picking up materials through the cooperation between the push rod, the spring, the guide wheel, and the guide closed-loop groove, and then automatically unfold a row of hook members during the subsequent drying and conveying process, so that the hooked glass fiber yarns can be evenly unfolded and spread out with both ends hanging down, so that the glass fiber yarns can have a larger contact area with the high-temperature hot air flow, which accelerates the drying speed of the glass fiber yarns and enables all the glass fiber yarns to be dried evenly without drying dead corners; the entire structural design is novel and ingenious, the grabbed glass fiber yarns do not need to be spread out manually, and the uniformity of the drying of the glass fiber yarns is effectively guaranteed.

[0022] The present invention further provides a vibrating mechanism inside the drying box. After the hook member unfolds and hangs the grabbed glass fiber yarn, the vibrating mechanism can be used to intermittently beat the hanging glass fiber yarn, thereby accelerating the shaking off of moisture on the surface of the glass fiber yarn. Combined with the effect of high-temperature hot air flow, the drying speed of the glass fiber yarn is further accelerated. BRIEF DESCRIPTION OF THE DRAWINGS

See the attached Figure 3 , the discharging unit 3 includes a second conveying seat 301 arranged on the bottom wall of the drying box 1 and extending out of the drying box 1. A second conveyor belt 302 located directly below the hanging material conveying unit 6 is arranged in the second conveying seat 301.

[0029] See the attached Figures 3 - 6 , the hanging material conveying unit 6 includes two rotating shafts 601 arranged at the left and right ends of the drying box 1, and a power device 602 is connected to the outer end of one of the rotating shafts 601. A transmission wheel 603 is arranged at the front and rear ends of each of the two rotating shafts 601, and then a closed-loop conveying member 600 is arranged between two groups of transmission wheels 603 aligned left and right. Specifically, the closed-loop conveying member 600 can be either a transmission chain or a transmission belt, and the transmission wheel 603 is correspondingly selected as a sprocket or a pulley.

[0030] A plurality of connecting columns 604 are fixedly connected to the two closed-loop conveying members 600 at equal intervals, and the connecting columns 604 on the two closed-loop conveying members 600 are arranged one by one in front and behind in alignment. At the ends of each pair of aligned connecting columns 604, a hollow rod 605 perpendicular to the closed-loop conveying member 600 is fixedly connected. A number of collar sleeves 606 equal to the number of slits 204 on the material guiding table 203 are sleeved on the hollow rod 605, specifically, it can be set between 3 and 7. Springs 607 are arranged between adjacent two collar sleeves 606. At the same time, a hook member 608 is rotatably connected to each collar sleeve 606. The top end of the hook handle of the hook member 608 is rotatably connected to the collar sleeve 606, and the hook body of the hook member 608 is arranged towards the side of the feeding unit 2. In the state where the spring 607 is not stressed, a plurality of collar sleeves 606 can be evenly distributed on the hollow rod 605 at equal intervals, so that a plurality of hook members 608 are evenly arranged along the axial direction of the hollow rod 605. In addition, linear notches 6051 are opened at both ends of the hollow rod 605. At both ends of the hollow rod 605 at the position of the linear notch 6051, a pushing ring 609 is arranged. And a pushing rod 610 extending out of the end of the hollow rod 605 is connected to the part of the pushing ring 609 extending into the inner cavity of the hollow rod 605 through the linear notch 6051, and a guide wheel 611 is arranged at the end of the pushing rod 610.

[0031] Closed-loop guide plates 612 parallel to the closed-loop conveying member 600 are fixedly arranged on the front and rear inner walls of the drying box 1. Closed-loop guide grooves 613 acting on the corresponding guide wheels 611 are opened on the closed-loop guide plates 612. The closed-loop guide groove 613 is composed of an inner section 6131, an outer section 6132 and an inclined line connecting section 6133. Among them, the inner section 6131 starts from the lower end of the closed-loop guide plate 612 on the right side of the discharging unit 3, extends all the way through the feeding unit 2, and then the end point is set on the left side of the upper end of the closed-loop guide plate 612. The outer section 6132 is arranged at other positions on the closed-loop guide plate 612 in a staggered manner, and the inner section 6131 and the outer section 6132 are connected by the inclined line connecting section 6133. When the guide wheel 611 acts on the inner section 6131, the two pushing rods 610 can move towards the midpoint of the hollow rod 605 at the same time. Then, through the squeezing force of the pushing ring 609 on the collar sleeve 606 and combined with the action of the spring 607, a plurality of hook members 608 can be shortened equidistantly towards the midpoint of the pushing rod 610, and each hook member 608 can be aligned with the slit 204 on the material guiding table 203. When the guide wheel 611 acts on the outer section 6132, the pushing rods 610 move towards the front and rear ends and expand at the same time. Then, under the action of the spring 607, a plurality of hook members 608 are expanded equidistantly along the entire hollow rod 605.

[0032] Refer to the appendix Figures 1 - 3The hot air unit 4 includes a hot air blower 401 or other heat sources. The hot air blower 401 in the figure is arranged on the upper surface of the drying box 1. The hot air blower 401 is connected to a hot air main pipe 402, and a plurality of hot air branch pipes 403 extending into the drying box 1 are arranged at equal intervals on the hot air main pipe 402. Each hot air branch pipe 403 is located in the closed-loop conveying member 600 and is arranged perpendicular to the closed-loop conveying member 600, and then each hot air branch pipe 403 is provided with a row of nozzles that are inclined upward and act on the glass fiber filaments in the upper hook member 608.

[0033] The negative pressure suction unit 5 includes a negative pressure pipe 501 disposed above the drying box 1, and the negative pressure pipe 501 is connected to the top of the drying box 1, and a filter box 502 is connected to the end of the negative pressure pipe 501, and a filter module and a drying module are disposed in the filter box 502, which can perform filtering and drying in sequence. Then, a negative pressure fan 503 is connected to the filter box 502, and the negative pressure fan 503 can also be replaced by other components such as a vacuum pump, so that it can generate negative pressure inside the negative pressure pipe 501 and the filter box 502.

[0034] Reference Figure 8 The material unloading mechanism 7 comprises a bracket 701 fixedly connected to the inner wall of the drying box 1, a swing arm stopper 702 is rotatably provided at the end of the bracket 701, and a driving device 703 for driving the swing arm stopper 702 to rotate is provided on the bracket 701. When unloading is required, the swing arm stopper 702 is rotated and driven by the driving device 703 to be perpendicular to a row of hook members 608, and then the hook members 608 are limited by the swing arm stopper 702 during the process of moving to the left, and then start to rotate upward, and after rotating a certain angle, they can slide off the hook members 608 and be received by the second conveyor belt 302, and finally be sent out of the drying box 1 by the second conveyor belt 302.

[0035] During the operation of the drying equipment for recycling and processing of glass fiber yarn disclosed in this embodiment 1, the glass fiber yarn to be dried is placed on the first conveyor belt 202 by a feeder or manually, and is transported to the guide table 203 inside the drying box 1 by the first conveyor belt 202. The front and rear closed-loop conveying members 600 operate synchronously under the action of the power device 602, the rotating shaft 601 and the transmission wheel 603, so that rows of hook members 608 are transported in a clockwise direction. When a row of hook members 608 is transported to the position of the guide table 203, the corresponding two guide wheels 611 interact with the inner section 6131 in the closed-loop guide groove 613, and a row of hook members 608 is in a compressed and close state and aligned with the slit 204, and then when the hook member 608 is lifted from the slit 204, the glass fiber yarn on the guide table 203 can be hooked up. When the corresponding two guide wheels 611 transition to the outer section 6132 through the oblique connecting section 6133, a row of hook members 608 can move away from each other, and the distance between two adjacent hook members 608 is equidistantly expanded, so that the concentrated glass fiber strands are evenly spread out, and the two ends of the spread glass fiber strands droop.

[0036] Subsequently, during the conveying process of the unfolded and drooped glass fiber filaments, they will be affected by the hot air flow discharged from the nozzle. Since the glass fiber filaments are fully unfolded and suspended, they can fully contact with the hot air flow and dry quickly. The hot and humid gas generated by drying is finally discharged and filtered by the negative pressure suction unit 5.

[0037] Finally, before moving to the discharge unit 3, the two guide wheels 611 interact with the inner section 6131 in the closed-loop guide groove 613, so that a row of hook members 608 are in a compressed and close state, and then move to the unloading toggle mechanism 7 to automatically rotate under the action of the swing arm stop bar 702. When the hook member 608 rotates to a certain angle, the dried glass fiber yarn can automatically slide down and be sent out of the drying box 1 by the second conveyor belt 302. Example 2

[0038] Example 2 discloses a drying device for glass fiber recycling and processing that is optimized and improved based on the technical solution in Example 1. The similarities between the drying device and Example 1 are not described again.

[0039] Reference Figure 1 , Attachment Figure 3 and attached Figure 9 In Example 2, a plurality of vibrating mechanisms 9 for beating and vibrating the suspended glass fiber yarns are arranged in the drying box 1. The glass fiber yarns suspended on the hook member 608 are beaten by the vibrating mechanisms 9 to accelerate the shaking off of the moisture on the surface thereof, and combined with the effect of the hot air flow, the drying speed thereof is improved.

[0040] The specific rapping mechanism 9 includes a rotating rod 901 rotatably arranged in the drying box 1. The end of the rotating rod 901 extending out of the drying box 1 is connected with a gear 902. A rotating motor 904 is arranged on the drying box 1 through a motor bracket 903, and an incomplete gear 905 interacting with the gear 902 is arranged on the output shaft of the rotating motor 904. An end ring 906 is fixed on the rotating rod 901, and then a torsion spring member 907 sleeved on the rotating rod 1 is connected between the end ring 906 and the inner wall of the drying box 1. Finally, radial connecting rods 908 are connected to both the front and rear ends of the rotating rod 901 located inside the drying box 1. A beating rod 909 capable of acting on the fiberglass filaments is connected to the ends of the two radial connecting rods 908, and both the rotating rod 901 and the beating rod 909 are arranged on the upper left side of the corresponding hot air branch pipe 403.

[0041] Through the above structural design in this Embodiment 2, when a row of hook members 608 are evenly unfolded, the centrally hooked fiberglass filaments will also be evenly unfolded, and the two ends of the unfolded fiberglass filaments will droop. Subsequently, when the fiberglass filaments move to the position of the rapping mechanism 9, the rotating motor 904 is started to make the incomplete gear 905 rotate. Then, the incomplete gear 905 first meshes with the gear 902, causing the beating rod 909 to rotate towards the side away from the fiberglass filaments and making the torsion spring member 907 rotate and store energy. When the incomplete gear 905 disengages from the gear 902, the beating rod 909 will quickly rotate towards the side of the fiberglass filaments under the action of the torsion spring member 907 and beat the suspended fiberglass filaments, causing the moisture in the fiberglass filaments to be vibrated and shaken off. Combined with the on-line drying of the hot air flow, the fiberglass filaments can be dried more quickly, improving the drying effect of the entire device on the fiberglass filaments.

[0042] 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 in the protection scope of the present invention.
