Description

Technical Field

[0001] This invention relates to the field of glass fiber technology, and in particular to a waste recycling device for glass fiber production. Background Technology

[0002] Glass fiber, as an important reinforcing material, is widely used in composite materials, building materials, electronic insulation, and other fields. During its production, especially in the production of chopped glass fiber, a large amount of process waste is inevitably generated. This waste mainly consists of broken or substandard chopped glass fiber monofilaments, whose diameters are typically between a few micrometers and tens of micrometers. While this physical size gives glass fiber a high specific surface area, it also results in significant brittleness and poor wear resistance.

[0003] In existing technologies, the recycling and treatment of this type of waste often employs simple collection devices or direct dumping. However, this method presents a critical and easily overlooked technical challenge: when the highly brittle glass fiber waste falls freely from a height on the production equipment or conveyor to the bottom of the collection container, it experiences a violent impact. The powerful shearing and impact forces generated by this impact far exceed the mechanical strength limit of micron-sized glass fibers, causing severe secondary breakage of the already fragile fibers. As a result, a large number of ultrafine fiber fragments with even smaller diameters (down to less than 1 micrometer) are generated in the waste. Due to their extremely light weight, these ultrafine fragments are easily suspended in the air by the airflow disturbance generated by the impact. This not only leads to a sharp increase in the glass fiber dust content in the air inside the production workshop, seriously polluting the working environment and posing a potential threat to the respiratory health of operators (occupational health risks), but also results in the additional loss of valuable recyclable fiber materials (fragmented into dust that cannot be effectively recycled) and may pollute the surrounding environment. In addition, existing simple collection devices often lack effective sealing measures, and unauthorized personnel may accidentally open them or operate them improperly, which can easily lead to the leakage of accumulated debris. The filters used for filtration or ventilation inside the device are also easily clogged by fiber debris and impurities, affecting the normal operating efficiency of the device and the internal airflow organization, and further aggravating the dust suspension problem.

[0004] Based on the above situation, there is an urgent need to develop a recycling device specifically designed for the characteristics of glass fiber waste. Summary of the Invention

[0005] In order to overcome the shortcomings of existing devices that lack a buffer structure and cause secondary breakage of glass fibers due to free fall impact, resulting in suspended dust pollution, the technical problem to be solved is to provide a waste recycling device for glass fiber production.

[0006] The technical solution of the present invention is as follows: a waste recycling device for glass fiber production, comprising a support base on which multiple electric push rods are installed. The telescopic part of the multiple electric push rods is fixedly connected to a loading box. The loading box slides vertically on the support base. The side wall of the loading box is slidably connected to symmetrically distributed closed doors. The top opening of the loading box is provided with symmetrically distributed bearing boxes. Each bearing box is slidably connected to a lower pressure frame. The two are connected by symmetrically distributed compression springs. The symmetrically distributed compression springs are all wound around the adjacent lower pressure frame. The top of each lower pressure frame is fixedly connected to a buffer pad.

[0007] Preferably, the loading box is equipped with a bidirectional electric push rod, and its symmetrically distributed telescopic parts are all fixedly connected to connecting rods, and are respectively fixedly connected to the adjacent carrying box through the connecting rods.

[0008] Preferably, a guide is fixed inside the loading box, and the two carrier boxes slide horizontally within the guide. The guide has symmetrically distributed inclined surfaces on its inner sidewall, and symmetrically distributed horizontal bend hook-shaped guide grooves on its inner wall. Each lower pressure frame has symmetrically distributed protrusions on the side near the guide groove, and these protrusions can slide within the adjacent guide groove.

[0009] Preferably, the symmetrically distributed telescopic parts of the bidirectional electric push rod are all fixedly connected to a fixed frame, and each part is fixedly connected to a rack at its bottom. The loading box is fixedly connected to a guide member on the side near the rack, and the rack slides horizontally on the guide member. Symmetrically distributed screws are rotatably connected to the bottom wall of the loading box, and each screw is fixedly connected to a one-way gear at its end. The one-way gear meshes with the adjacent rack. Symmetrically distributed moving parts are threadedly connected to each screw, and each moving part is rotatably connected to a connecting rod. A bearing platform is provided between the other ends of each connecting rod. The bearing platform moves up and down inside the loading box, and the bearing platform is in close contact with the inner wall of the loading box.

[0010] Preferably, the loading box has symmetrically distributed barrier frames that slide on the side near the closed hatch, which engage with the adjacent closed hatch, and the bottom of the loading box is provided with a locking component.

[0011] Preferably, the positioning assembly includes a positioning frame symmetrically and slidably connected to the bottom of the loading box, which is connected to the bottom wall of the loading box by a tension spring. The tension spring is wound around the loading box, and the symmetrically distributed blocking frames have a locking slot on the side near the positioning frame.

[0012] Preferably, each movable component near the card holder is fixed with a fixing block, and the card holders are provided with an inclined surface on the side that is close to each other.

[0013] Preferably, the support base is fixed to a receiving frame on the side near the barrier frame, and each slot frame has an inclined surface at the bottom to form a cooperating structure with the barrier frame.

[0014] The beneficial effects of this invention are as follows: This invention significantly improves waste collection efficiency through the synergistic effect of an automatic push-pull mechanism, a material pushing mechanism, and a height adjustment platform; the automatic push-pull function reduces manual intervention and labor intensity; the material pushing mechanism enables fully automatic transfer of waste, avoiding residue; the height adjustment platform effectively reduces the impact of falling waste, lowers the risk of secondary damage to glass fibers, and improves the utilization rate of recyclable materials; at the same time, the enclosed design reduces dust emissions and ensures a healthy and safe working environment.

[0015] This invention effectively prevents the sealed compartment door from being opened accidentally through a self-locking mechanism, linkage unlocking, and automatic reset function, thus avoiding the leakage of fiberglass waste and the resulting health hazards to workers. The self-locking structure ensures that the loading box will not be opened when it is not full, and the linkage mechanism enables automatic unlocking when fully loaded, simplifying the operation process. The reset process requires no manual intervention, improving work efficiency, ensuring operational safety, reducing dust emissions, and optimizing the working environment.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: A waste recycling device for glass fiber production, such as Figures 1-3 As shown, the system includes a support base 1 serving as the main load-bearing component, on which multiple sections of electric push rods 13 are mounted. The telescopic parts of the multiple sections of electric push rods 13 are fixedly connected to a loading box 11 for collecting waste materials used in glass fiber production. The loading box 11 slides vertically on the support base 1. The side walls of the loading box 11 are slidably connected to symmetrically distributed closed doors 12 to achieve sealed loading and waste unloading functions. The top opening of the loading box 11 is provided with symmetrically distributed carrying boxes 22 for temporarily storing defective waste materials picked up by workers. The top of the carrying boxes 22 and the top of the loading box 11 have a material stacking space. Each carrying box 22 is slidably connected to a lower pressure frame 25, which is connected to the other two by symmetrically distributed compression springs 26. The symmetrically distributed compression springs 26 are all wound around the adjacent lower pressure frame 25, thereby achieving the waste material shock absorption and buffering function. The top of each lower pressure frame 25 is fixedly connected to a buffer pad 24, and in the initial state, its top is flush with the top of the carrying box 22.

[0025] During the waste collection process, the support base 1 is first positioned near the unloading platform. The height adjustment function of the multi-section electric push rod 13 is used to raise or lower the loading box 11 to adjust the carrying box 22 to a suitable working height. The worker places the waste from the glass fiber production into the carrying box 22. The waste first falls onto the buffer pad 24. The elastic material properties of the buffer pad 24 directly absorb part of the impact energy, reducing the violent collision between the waste and the lower pressure frame 25.

[0026] Under the force of gravity, the waste material pushes the buffer pad 24 and the fixed lower pressure frame 25 downward relative to the carrier box 22, causing the compression spring 26 to deform. The reverse elastic force generated by the compression spring 26 continues to act on the lower pressure frame 25, significantly slowing down the falling speed of the waste material and further weakening the impact force. This dual buffering mechanism effectively reduces the risk of breakage of brittle glass fiber due to falling impact.

[0027] As waste material is continuously fed in, under the influence of gravity, the lower pressure frame 25 drives the buffer pad 24 to move downwards, increasing the deformation of the compression spring 26. The waste material gradually fills the carrier box 22 and accumulates upwards until it is flush with the top of the loading box 11. During this process, the carrier box 22 and the inner wall of the loading box 11 form an enclosed space, effectively suppressing the airflow of lightweight glass fiber waste, reducing the dust concentration in the work area, and protecting the respiratory health of workers.

[0028] When the carrier box 22 is full and waste needs to be transferred, the operator pulls the carrier box 22 outward horizontally. As the carrier box 22 moves outward, the waste accumulated inside it (especially the part higher than the wall of the carrier box 22) is blocked by the inner wall of the loading box 11, and this part of the waste will be scraped into the loading box 11. As the carrier box 22 continues to move outward, the operator manually pushes the waste remaining in the carrier box 22 into the loading box 11 below.

[0029] After the waste transfer is complete, the carrier box 22 is pushed inward and reset. At this time, the top of the loading box 11 returns to a relatively sealed state to prevent the collected waste from scattering and polluting the environment. After the waste in the carrier box 22 is emptied, the downward pressure on the buffer pad 24 disappears. Under the restoring force of the compression spring 26, the lower pressure frame 25 drives the buffer pad 24 to slide upward and reset to its initial position (the top surface of the buffer pad 24 is flush with the top surface of the carrier box 22), preparing for receiving the next batch of waste.

[0030] In the process of recycling waste from glass fiber production, the carrier box 22 needs to be frequently pulled out and pushed back to temporarily store and transfer the waste. Relying on manual operation not only increases labor costs but may also lead to low work efficiency. Therefore, an automatic push-pull mechanism needs to be designed to automate the movement of the carrier box 22, thereby improving waste transfer efficiency and reducing manual intervention.

[0031] like Figure 2 As shown, specifically, the loading box 11 is equipped with a bidirectional electric push rod 2, and each of its symmetrically distributed telescopic parts is fixedly connected to a connecting rod 21, which is then fixedly connected to the adjacent carrying box 22 via the connecting rod 21. This bidirectional electric push rod 2 has an automatic telescopic function, which can drive the connecting rod 21 to achieve outward and inward movement of the carrying box 22.

[0032] During waste collection, when the carrier box 22 is full of waste, the automatic extension and retraction function of the bidirectional electric push rod 2 is controlled to move the connecting rod 21 outward, thereby causing the carrier box 22 to move automatically outward. At this time, the carrier box 22 no longer seals the top of the loading box 11, making it easier to transfer the waste in the carrier box 22 into the loading box 11. After the waste transfer is completed, the automatic extension and retraction function of the bidirectional electric push rod 2 is controlled again to move the connecting rod 21 inward, thereby causing the carrier box 22 to automatically move inward and reset, restoring the closed state of the top of the loading box 11, so as to continue the temporary storage of waste.

[0033] During waste collection, as waste is continuously loaded into the carrier box 22, due to the limited space in the carrier box 22, some waste will rise above its top and accumulate to be level with the top of the loading box 11. When the carrier box 22 is pulled outward, the waste above the top of the carrier box 22 will be blocked by the inner wall of the loading box 11 and automatically fall into the loading box 11; however, a small amount of waste in the carrier box 22 needs to be manually pushed into the loading box 11, which not only increases labor intensity but also reduces work efficiency. Therefore, an automatic pushing mechanism needs to be designed to enable the waste in the carrier box 22 to be transferred to the loading box 11 automatically, thereby improving the waste transfer efficiency.

[0034] like Figure 2 and Figure 3 As shown, specifically, a guide 23 is fixedly connected inside the loading box 11, and two carrier boxes 22 slide horizontally within the guide 23. The guide 23 has symmetrically distributed inclined surfaces on its inner sidewall, used to scrape waste material falling on the buffer pad 24 into the loading box 11. At the same time, symmetrically distributed horizontal bend hook-shaped guide grooves are opened on the inner wall of the guide 23, and each lower pressure frame 25 has symmetrically distributed protrusions on the side near the guide groove, which can slide within the adjacent guide groove.

[0035] During the waste collection process, as waste is continuously loaded into the carrier box 22, the lower pressure frame 25 will cause the buffer pad 24 to slide downward relative to the carrier box 22 under the action of gravity, and the compression spring 26 will be gradually compressed. At this time, the protrusion on the lower pressure frame 25 slides vertically along the horizontal bend hook-shaped guide groove.

[0036] When the carrier box 22 is pulled outward by the connecting rod 21, the carrier box 22 drives the lower pressure frame 25 and the buffer pad 24 to move outward together, and the protrusion of the lower pressure frame 25 slides upward along the guide groove. The horizontal section of the guide groove lifts the lower pressure frame 25 upward through the protrusion, so that the top of the buffer pad 24 is flush with the top of the carrier box 22, and the compression spring 26 returns to its initial length. At this time, the waste on the buffer pad 24 is lifted up and flush with the bottom of the inclined surface of the guide member 23.

[0037] As the carrier box 22 continues to move outward, the top of the buffer pad 24 contacts the guide 23, and the inclined surface of the guide 23 blocks all the waste material on the buffer pad 24. As the buffer pad 24 moves outward relative to the guide 23, the inclined surface of the guide 23 scrapes the waste material into the loading box 11, thereby realizing the automatic transfer of waste material.

[0038] When the protrusion of the lower pressure frame 25 moves to the end of the guide groove, the lower pressure frame 25 is restricted to its maximum distance, ensuring that the carrier box 22 is accurately positioned and the waste material is completely transferred. When the carrier box 22 is reset, the protrusion of the lower pressure frame 25 returns to the starting position of the guide groove, regaining the space to slide downwards.

[0039] During the transfer of waste from the carrier box 22 to the loading box 11, due to the height difference between the bottom wall of the loading box 11 and the carrier box 22, the waste falling directly into the loading box 11 can cause secondary breakage of the glass fibers due to impact. In particular, the fragile glass fiber wool is prone to generating a large amount of ultrafine fiber debris, resulting in additional loss of recyclable fiber materials. Therefore, it is necessary to design a lifting platform with height adjustment function, which can gradually lower the height according to the amount of waste collected, thereby reducing the impact force during the waste transfer process and reducing damage to the glass fibers.

[0040] like Figure 4 As shown, specifically, each of the symmetrically distributed telescopic parts of the bidirectional electric push rod 2 is fixedly connected to a fixing frame 3, and each of them is fixedly connected to a rack 31. The loading box 11 is fixedly connected to a guide member 32 on the side near the rack 31, which is used to guide the rack 31 to slide horizontally and limit its movement trajectory. The rack 31 slides horizontally on the guide member 32 to ensure that the transmission process is smooth and reliable.

[0041] The loading box 11 has symmetrically distributed screws 34 rotatably connected to its bottom wall, and each screw has a one-way gear 33 fixed to its side near the rack 31. The one-way gear 33 meshes with the adjacent rack 31 to form a gear transmission system, realizing the function of the rack 31 moving horizontally to drive the screws 34 to rotate.

[0042] Each screw 34 is threadedly connected to a symmetrically distributed movable part 35, and each is rotatably connected to a connecting rod 36. A bearing platform 37 is provided between the other ends of each connecting rod 36. The bearing platform 37 moves up and down within the loading box 11 and has a height adjustment function, which can gradually lower the height according to the amount of waste collected, thereby reducing the impact force during the waste transfer process.

[0043] The bearing platform 37 is in close contact with the inner wall of the loading box 11 to prevent waste from leaking out from the gap between the bearing platform 37 and the loading box 11, while ensuring the stability and sealing of the bearing platform 37 during operation.

[0044] When the bidirectional electric push rod 2 drives the fixed frame 3 to move outward via the connecting rod 21, the rack 31 slides horizontally along the guide member 32. Since the rack 31 meshes with the one-way gear 33, its outward movement will drive the one-way gear 33 to rotate, thereby driving the moving member 35 to move outward via the screw 34.

[0045] Simultaneously, the displacement of the moving part 35 is converted into the vertical downward movement of the carrying platform 37 via the connecting rod 36, gradually increasing the distance between the carrying platform 37 and the carrying box 22, ensuring that the waste can be smoothly transferred from the carrying box 22 to the carrying platform 37. During this process, the waste accumulated on the buffer pad 24 is scraped into the carrying platform 37 by the guide part 23, realizing the orderly collection of waste.

[0046] When the carrier box 22 resets, the fixing frame 3 and the rack 31 move inward synchronously to reset, while the one-way gear 33 remains stationary due to its design characteristics, without generating additional transmission. After each waste transfer, the carrier platform 37 gradually descends a certain distance according to the settings until it reaches the lowest point, indicating that the loading box 11 is close to full load.

[0047] At this point, the closed hatch 12 can be opened to manually remove the waste material from the carrying platform 37 and restore the loading space. After cleaning, the operator can reverse the screw 34 to drive the moving part 35 to move inward, and use the connecting rod 36 to reset the carrying platform 37 to its initial height, so as to maintain an appropriate distance between the carrying platform 37 and the carrying box 22, avoid collision damage to the waste material due to excessive height difference during the transfer process, and effectively reduce the breakage rate of the waste material.

[0048] Example 2: In the waste collection device, the loading box 11 is used to store fiberglass waste. Due to the lightweight and easily dispersed nature of fiberglass, workers may suffer health damage from inhalation or skin contact with waste dust without proper protective measures. Therefore, a self-locking mechanism is needed to prevent the sealed door 12 from being accidentally opened when the loading box 11 is not full, thus avoiding the waste from overflowing due to airflow and causing injury to workers not wearing protective measures; simultaneously, it ensures that the sealed door 12 can only be opened when the loading box 11 is full and workers have taken protective measures.

[0049] like Figure 5 and Figure 6 As shown, the specific design is as follows: The loading box 11 has symmetrically distributed barrier frames 4 slidably connected to one side near the closed hatch 12. Their function is to lock the position of the closed hatch 12 and prevent it from opening accidentally. Simultaneously, the bottom of the loading box 11 is equipped with a locking assembly to fix the position of the barrier frames 4, ensuring that the closed hatch 12 is in a locked state.

[0050] When it is necessary to open the sealed hatch 12, the operator must manually move the locking component to disengage it from the arresting frame 4. Subsequently, the arresting frame 4 will automatically slide downwards under its own weight, separating from the sealed hatch 12 and thus releasing the lock on the sealed hatch 12. At this time, the sealed hatch 12 can be freely slid outwards and opened.

[0051] To ensure clearer locking and unlocking functions of the closed hatch 12, the locking assembly specifically includes a locking frame 41 symmetrically slidably connected to the bottom of the loading box 11, which is connected to the bottom wall of the loading box 11 via a tension spring 42. The tension spring 42 is wound around the loading box 11 to provide a return spring force. The symmetrically distributed blocking frames 4 are all provided with slots that match the locking frame 41 to achieve a stable connection between the blocking frame 4 and the locking frame 41.

[0052] In its initial state, the arresting arm 4 engages with the locking frame 41 via a latch, thus holding the arresting arm 41 in a stable locked state and effectively preventing the sealed hatch 12 from opening due to accidental operation. When it is necessary to unlock the sealed hatch 12, the operator must manually push the locking frame 41 away from the arresting arm 4. At this time, the tension spring 42 undergoes elastic deformation, and the locking frame 41 disengages from the latch of the arresting arm 4. After losing support, the arresting arm 4 falls freely under its own weight, releasing the lock on the sealed hatch 12.

[0053] After unlocking, the closed hatch 12 can be opened freely. After releasing the locking bracket 41, under the elastic force of the tension spring 42, the locking bracket 41 automatically slides back to its initial state for the next use.

[0054] In the waste collection device, in order to prevent the glass fiber waste from leaking out due to airflow and endangering the health of workers by accidentally opening the closed door 12 when the loading box 11 is not full, a linkage mechanism needs to be designed to ensure that the closed door 12 is automatically unlocked only when the loading box 11 is full.

[0055] As mentioned above, when the carrying platform 37 is lowered to its lowest point, i.e., when the loading box 11 is fully loaded, the movement of the moving part 35 triggers the unlocking process of the closed hatch 12. This ensures that the unlocking mechanism is simple and reliable, and also has a foolproof function to avoid human error.

[0056] Specifically, each movable component 35 near the mounting bracket 41 is fixedly connected to a fixing block 43, and the mounting bracket 41 has an inclined surface on the side closest to each other to form a pressing fit with the fixing block 43. The purpose is to achieve the automatic unlocking function of the closed hatch 12 through the movement of the movable component 35.

[0057] When the movable part 35 moves outward, the fixed block 43 moves outward accordingly and contacts the inclined surface of the locking frame 41 through its end. The fixed block 43 presses against the inclined surface of the locking frame 41, causing the locking frame 41 to slide to the right, thereby disengaging from the barrier frame 4. The tension spring 42 undergoes elastic deformation, and the barrier frame 4 falls freely under the action of gravity, releasing the lock on the closed hatch 12.

[0058] When the moving part 35 resets inward, the fixed block 43 moves inward accordingly and no longer abuts against the inclined surface of the locking frame 41. Under the elastic force of the tension spring 42, the locking frame 41 slides back to reset and returns to its initial state for the next use.

[0059] In the waste collection device, in order to improve the automation of locking and unlocking of the closed hatch 12 and avoid the inefficiency caused by manually operating the barrier frame 4 to reset, a linkage locking mechanism needs to be designed to ensure that the closed hatch 12 can automatically re-engage and lock with the barrier frame 4 after being pushed together.

[0060] The automatic engagement of the barrier frame 4 and the locking frame 41 can be achieved by using the up-and-down movement of the loading box 11 and the multi-section electric push rod 13. This ensures that the entire reset and locking process is simple and reliable, requiring no manual intervention.

[0061] Specifically, a receiving frame 44 is fixedly connected to the side of the support base 1 near the barrier frame 4, for supporting the barrier frame 4 when it is detached. Each locking frame 41 has an inclined surface at its bottom, forming a mating structure with the barrier frame 4. This design aims to achieve automatic reset and locking of the barrier frame 4 through the up-and-down movement of the loading box 11.

[0062] When the positioning frame 41 disengages from the barrier frame 4, the barrier frame 4 falls onto the receiving frame 44 under its own weight, completing the initial support. By controlling the multi-section electric push rod 13, the loading box 11 is moved downward, thereby causing the positioning frame 41 to move downward relative to the barrier frame 4. At the same time, the loading box 11 will cause the closed hatch 12 to move downward relative to the barrier frame 4, so that the barrier frame 4 is inserted back into its original position until the closed hatch 12 is locked by the barrier frame 4 again.

[0063] During this process, when the bottom slope of the locking frame 41 contacts the blocking frame 4, the locking frame 41 will be pressed against and slide to the right, and the tension spring 42 will undergo elastic deformation. When the bottom slope of the locking frame 41 passes the blocking frame 4, under the elastic force of the tension spring 42, the locking frame 41 will slide to the left to reset and lock the blocking frame 4.

[0064] Subsequently, the loading box 11 is moved upward until the buffer pad 24 reaches the appropriate height. At the same time, the blocking frame 4 is moved upward by the locking frame 41, so that the blocking frame 4 is separated from the receiving frame 44, thus completing the entire reset and locking process.

[0065] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
