Description

Technical Field

[0001] This utility model relates to the field of glass fiber production, and in particular to an electronic-grade glass fiber recycling device. Background Technology

[0002] During the drawing and cutting process of electronic-grade glass fiber, glass fiber waste is generated. In order to reduce costs, the glass fiber waste is crushed and collected for recycling. However, during the crushing and recycling process, because the glass fiber waste is relatively long, if it is directly put into the roller crusher, the glass fiber waste may become entangled on the crushing roller, which may cause the machine to stop, affecting the recycling efficiency and increasing the workload of the staff.

[0003] The technical problem that this invention needs to solve is: how to prevent glass fiber waste from getting tangled on the crushing unit. Utility Model Content

[0004] The main purpose of this invention is to provide an electronic-grade glass fiber recycling device. The device uses a vertically arranged primary crushing unit to initially crush the glass fiber. The vertical arrangement of the primary crushing unit can reduce entanglement. A strip-shaped through hole is provided in the first receiving cavity. Only after the glass fiber is broken into a smaller length will it pass through the strip-shaped through hole and enter the secondary crushing unit for further crushing. This avoids the glass fiber being too long and getting entangled in the secondary crushing unit, which would cause the machine to stop.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] An electronic-grade glass fiber recycling device includes a housing, a primary crushing unit, a secondary crushing unit, a collection unit, and a feeding plate. The housing has a feed inlet at its top. The housing has a first receiving cavity and a second receiving cavity from top to bottom. The first receiving cavity communicates with the feed inlet, and a strip-shaped through-hole is provided on the bottom surface of the first receiving cavity, communicating with the second receiving cavity. The secondary crushing unit and the collection unit are connected from top to bottom within the second receiving cavity, and the strip-shaped through-hole is located directly above the secondary crushing unit. The primary crushing unit is rotatably connected within the first receiving cavity. The feeding plate is located within the first receiving cavity and is used to push the glass fibers crushed by the primary crushing unit into the strip-shaped through-hole so that the glass fibers enter the secondary crushing unit for further crushing.

[0007] Preferably, the first receiving cavity includes a first sub-chamber and a second sub-chamber connected sequentially from top to bottom; the space of the first sub-chamber gradually narrows from top to bottom; the second sub-chamber is a cylindrical chamber; and the strip-shaped through hole is disposed on the bottom surface of the second sub-chamber.

[0008] Preferably, the primary crushing unit includes a first drive module, a rotating rod, and cutting blades; the first drive module is disposed at the top of the housing; the power output end of the first drive module is connected to the end of the rotating rod; the rotating rod is rotatably connected within a first receiving cavity; the rotating rod extends vertically in its length direction; there are multiple cutting blades, which are spaced apart from top to bottom on the rotating rod; and the feeding plate is disposed at the bottom of the rotating rod.

[0009] Preferably, the length of the cutting blade extends radially along the first sub-chamber, one end of the cutting blade along its length is connected to the rotating rod, and the length of the plurality of cutting blades gradually decreases along the top-to-bottom direction, with a gap between the end of each cutting blade away from the rotating rod along its length and the cavity wall of the first sub-chamber.

[0010] Preferably, the secondary crushing unit includes a second drive module and crushing rollers; there are two crushing rollers, both of which are rotatably connected in the second accommodating cavity, the two crushing rollers are spaced apart and a crushing space is formed between them, the second drive module is disposed on the housing and is connected to the two crushing rollers, the second drive module is used to drive the two crushing rollers to rotate in opposite directions.

[0011] Preferably, the collection unit includes a push-pull trolley and a collection frame; the collection frame is detachably connected to the push-pull trolley; the collection frame is located below the secondary crushing unit; the bottom of the push-pull trolley is provided with rollers; the side wall of the second receiving cavity is provided with an opening; the push-pull trolley is inserted into the second receiving cavity through the opening, and the push-pull trolley can drive the collection frame out of the second receiving cavity.

[0012] Preferably, the bottom surface of the second receiving cavity is provided with two symmetrically arranged grooves; the length direction of the grooves extends from left to right, and the grooves communicate with the opening, each groove accommodating the roller, and the grooves are used to limit the displacement of the push-pull cart.

[0013] Preferably, the electronic-grade glass fiber recycling device further includes a conveying unit and a filtering unit; the filtering unit is connected in the second receiving cavity and is located between the secondary crushing unit and the collecting unit; the conveying unit is connected to the side wall of the housing; the filtering unit is used to filter the glass fibers crushed by the secondary crushing unit; the conveying unit is used to convey the unqualified glass fibers after filtration to the primary crushing unit.

[0014] Preferably, the conveying unit is a screw conveyor, the inlet of the screw conveyor is located in the second receiving cavity, and the inlet is located below the secondary crushing unit, and the outlet of the screw conveyor is connected to the first receiving cavity; the filtering unit is a linear vibrating screen, one end of the linear vibrating screen along its conveying direction is located directly above the inlet, and the other end extends upward at an inclined angle for a predetermined distance.

[0015] Compared with existing technologies, this solution has the following advantages:

[0016] In the recycling device of this case, after the glass fiber enters the first receiving cavity, the primary crushing unit performs preliminary crushing on the glass fiber. By placing the primary crushing unit vertically, the probability of the glass fiber getting tangled in the primary crushing unit is reduced. Secondly, a strip-shaped through hole is provided at the bottom of the first receiving cavity. By controlling the size of the strip-shaped through hole, the shorter length of the glass fiber crushed by the primary crushing unit can enter the secondary crushing unit, while the glass fiber that has not been crushed can continue to remain in the first receiving cavity for further crushing. This avoids the situation where excessively long glass fibers get tangled in the secondary crushing unit, causing the secondary crushing unit to jam and resulting in a shutdown.

[0017] Secondly, by using secondary crushing, the glass fibers can be crushed more evenly. Moreover, by setting the length direction of the strip-shaped through holes to extend along the length direction of the secondary crushing unit, the glass fibers crushed by the primary crushing unit can be evenly scattered in the middle position of the secondary crushing unit for crushing. This avoids the glass fibers falling from the side of the secondary crushing unit into the collection unit, resulting in the glass fibers being collected without being crushed to the qualified size by the secondary crushing unit.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] refer to Figure 1-3 An electronic-grade glass fiber recycling device includes a housing 1, a primary crushing unit 2, a secondary crushing unit 3, a collection unit 4, and a feeding plate 21. The housing 1 has a feed inlet 11 at its top. The housing 1 has a first receiving cavity 12 and a second receiving cavity 13 arranged from top to bottom. The first receiving cavity 12 communicates with the feed inlet 11, and the bottom surface of the first receiving cavity 12 has a strip-shaped through hole 14 communicating with the second receiving cavity 13. The secondary crushing unit 3 and the collection unit 4 are connected from top to bottom within the second receiving cavity 13, and the strip-shaped through hole 14 is located directly above the secondary crushing unit 3. The primary crushing unit 2 is rotatably connected within the first receiving cavity 12. The feeding plate 21 is located within the first receiving cavity 12 and is used to push the glass fibers crushed by the primary crushing unit 2 into the strip-shaped through hole 14 so that the glass fibers enter the secondary crushing unit 3 for further crushing.

[0024] In this embodiment, the specific workflow of the recycling device is as follows: the worker puts the electronic-grade glass fiber waste into the first receiving cavity 12, the primary crushing unit 2 performs preliminary crushing of the electronic-grade glass fiber waste, cutting the electronic-grade glass fiber waste into shorter glass fibers, the feeding plate 21 rotates to push the glass fibers to move, so that the glass fibers enter the second receiving cavity 13 through the strip-shaped through hole 14, and are crushed by the secondary crushing unit 3. The glass fibers that have passed through the secondary crushing unit 3 then enter the collection unit 4 for collection.

[0025] It should be noted that by setting the length of the primary crushing unit 2 to extend vertically, in other words, the primary crushing unit 2 is arranged vertically in the first receiving cavity 12, electronic-grade glass fiber waste is less likely to get tangled on the primary crushing unit 2.

[0026] Secondly, the strip-shaped through hole 14 is located directly above the secondary crushing unit 3, and the length direction of the strip-shaped through hole 14 extends along the length direction of the secondary crushing unit 3, so that the glass fiber crushed by the primary crushing unit 2 can fall into the secondary crushing unit 3 for crushing as much as possible, avoiding the situation where the glass fiber falls from both sides of the secondary crushing unit 3 to the collection unit 4 and is not completely crushed and collected.

[0027] Preferably, the first receiving cavity 12 includes a first sub-cavity 15 and a second sub-cavity 16 connected sequentially from top to bottom; the space of the first sub-cavity 15 gradually narrows from top to bottom; the second sub-cavity 16 is a cylindrical cavity; the strip-shaped through hole 14 is disposed on the bottom surface of the second sub-cavity 16.

[0028] In this embodiment, by providing a first sub-chamber 15, the falling speed of the electronic-grade glass fiber waste when it enters the first receiving cavity 12 can be slowed down, thereby enabling the primary crushing unit 2 to better crush the electronic-grade glass fiber waste. A second sub-chamber 16 is provided to temporarily store the glass fibers crushed by the primary crushing unit 2, and then the glass fibers are pushed through the strip-shaped through-hole 14 into the second receiving cavity 13 by the feeding plate 21.

[0029] Preferably, the primary crushing unit 2 includes a first drive module 22, a rotating rod 23, and cutting blades 24; the first drive module 22 is disposed on the top of the housing 1; the power output end of the first drive module 22 is connected to the end of the rotating rod 23; the rotating rod 23 is rotatably connected in the first receiving cavity 12; the length direction of the rotating rod 23 extends vertically; there are multiple cutting blades 24, which are spaced apart from top to bottom on the rotating rod 23; the feeding plate 21 is disposed at the bottom of the rotating rod 23.

[0030] In this embodiment, the working process of the first-stage crushing unit 2 is as follows: the first drive module 22 drives the rotating rod 23 to rotate, thereby driving the cutting blade 24 to rotate. When the electronic-grade glass fiber waste enters the first receiving cavity 12, the cutting blade 24 cuts the electronic-grade glass fiber waste, thereby cutting the electronic-grade glass fiber waste into glass fibers with shorter lengths, and entering the second sub-cavity 16. The feeding plate 21 rotates together with the rotating rod 23, thereby pushing the glass fibers from the strip-shaped through hole 14 into the second receiving cavity 13.

[0031] The first drive module 22 is a motor.

[0032] Preferably, the cutting blade 24 extends radially along the length direction of the first sub-chamber 15, and one end of the cutting blade 24 along its length direction is connected to the rotating rod 23. Along the top-to-bottom direction, the length of the plurality of cutting blades 24 gradually shortens, and the end of each cutting blade 24 away from the rotating rod 23 along its length direction has a gap with the cavity wall surface of the first sub-chamber 15.

[0033] In this embodiment, the length of the cutting blade 24 is adapted to the shape of the first sub-chamber 15. That is, the distance between the end of the cutting blade 24 and the inner wall of the first sub-chamber 15 is 1 mm. Alternatively, the end of the cutting blade 24 can be set to contact the inner wall of the first sub-chamber 15, or the distance between the end of the cutting blade 24 and the inner wall of the first sub-chamber 15 can be other values, depending on actual needs. This design allows electronic-grade glass fiber waste to be cut while minimizing the amount of electronic-grade glass fiber waste entangled on the rotating rod 23.

[0034] Preferably, the secondary crushing unit 3 includes a second drive module 31 and crushing rollers 32; there are two crushing rollers 32, both of which are rotatably connected in the second receiving cavity 13, the two crushing rollers 32 are spaced apart and form a crushing space between them, the second drive module 31 is mounted on the housing 1 and is connected to the two crushing rollers 32, the second drive module 31 is used to drive the two crushing rollers 32 to rotate in opposite directions.

[0035] In this embodiment, the working process of the secondary crushing unit 3 is as follows: two crushing rollers 32 are symmetrically arranged in the second receiving cavity 13, glass fibers fall from the strip-shaped through hole 14 into the crushing space between the two crushing rollers 32, and the second driving module 31 drives the two crushing rollers 32 to rotate in opposite directions, thereby crushing the glass fibers.

[0036] The second drive module 31 includes a motor and a synchronous belt. The motor is connected to the housing 1 and is connected to one of the crushing rollers 32 via the synchronous belt. Both crushing rollers 32 have gears at their ends, which mesh with each other. When the motor drives one of the crushing rollers 32 to rotate via the synchronous belt, the other crushing roller 32 rotates along with it via the gear, thereby realizing that the two crushing rollers 32 rotate towards each other.

[0037] Preferably, the collection unit 4 includes a push-pull trolley 41 and a collection frame 42; the collection frame 42 is detachably connected to the push-pull trolley 41; the collection frame 42 is located below the secondary crushing unit 3; the bottom of the push-pull trolley 41 is provided with rollers 43; the side wall of the second receiving cavity 13 is provided with an opening 17; the push-pull trolley 41 is inserted into the second receiving cavity 13 through the opening 17, and the push-pull trolley 41 can drive the collection frame 42 to detach from the second receiving cavity 13.

[0038] In this embodiment, the side wall of the second receiving cavity 13 is provided with an opening 17. Workers push a trolley 41 through the opening 17 to enter and exit the second receiving cavity 13. The collection frame 42 is detachably connected to the trolley 41. When the collection frame 42 is full, the worker pulls out the trolley 41 and replaces the empty collection frame 42. In this way, workers do not need to directly contact the fiberglass, avoiding fiberglass punctures to the worker's skin and improving safety.

[0039] By setting a limiting groove 18 at the bottom of the collection box 42 and setting a limiting post at the position corresponding to the limiting groove 18 on the push-pull cart 41, the limiting post is inserted into the limiting groove 18, thereby enabling the collection box 42 to be detachably connected to the push-pull cart 41.

[0040] Preferably, the bottom surface of the second receiving cavity 13 is provided with two symmetrically arranged grooves 18; the length direction of the grooves 18 extends from left to right, and the grooves 18 communicate with the opening 17. Each groove 18 accommodates the roller 43, and the grooves 18 are used to limit the offset of the push-pull cart 41.

[0041] In this embodiment, by setting the groove 18, when the push-pull cart 41 enters the second receiving cavity 13, the roller 43 of the push-pull cart 41 enters the groove 18, thereby limiting the push-pull cart 41 and preventing the push-pull cart 41 from deviating and affecting the collection frame 42 in collecting glass fibers.

[0043] In this embodiment, the recycling device is equipped with a conveying unit 5 and a filtering unit 6. After the secondary crushing unit 3 crushes the glass fiber, a small portion of the glass fiber may not be crushed to the qualified size. The filtering unit 6 can screen out the glass fiber of the qualified size, while the unqualified glass fiber enters the conveying unit 5 from the filtering unit 6. The conveying unit 5 transports the unqualified glass fiber back to the first receiving cavity 12 for re-crushing.

[0044] Preferably, the conveying unit 5 is a screw conveyor, the inlet of which is located in the second receiving cavity 13 and below the secondary crushing unit 3, and the outlet of which is connected to the first receiving cavity 12; the filtering unit 6 is a linear vibrating screen, one end of which is located directly above the inlet along its conveying direction, and the other end extends upward at an inclined angle for a predetermined distance.

[0045] In this embodiment, the preset distance can be determined based on the size of the secondary crushing unit 3, or set according to actual needs. The conveying unit 5 is a screw conveyor, also called an auger conveyor. The screw conveyor has an inlet and an outlet. The outlet is connected to the first receiving cavity 12, and the inlet is connected to the second receiving cavity 13. The linear vibrating screen screens the crushed glass fibers. Qualified glass fibers fall into the collection unit 4 after screening, while unqualified glass fibers enter the screw conveyor from the inlet and are conveyed by the screw conveyor to the first receiving cavity 12 for re-crushing.

[0046] Linear vibrating screens and screw conveyors are both existing technologies. A linear vibrating screen consists of a filter plate, a vibrating motor, and springs. The vibrating motor drives the filter plate to vibrate and screen the material. The springs are connected to the bottom of the filter plate to prevent the vibration of the filter plate from affecting the operation of other components.
