[0035] In order to better understand the purpose, function and specific design scheme of the present invention, the glass fiber waste chopped short production line of the present invention is further described in detail below with reference to the accompanying drawings.

[0036] like Figure 1As shown, the glass fiber waste chopped short production line of the present invention includes a cutter 1, a vibrating feeder 2, a first conveying device 3, a roller cutter 4, a first vibrating screen 5, a second conveying device 6, a second vibrating screen 7, a third conveying device 8, and a fourth conveying device 9. A vibrating feeder 2 is provided on one side of the cutter 1 and is connected to the discharge port of the cutter 1 for vibrating and dispersing the fibers cut by the cutter 1. The vibrating feeder 2 is connected to the roller cutter 4 via the first conveying device 3. The first conveying device 3 is used to transport the fibers vibrated and dispersed by the vibrating feeder 2 to the roller cutter 4 for cutting. A first vibrating screen 5 is provided below the roller cutter 4 and is connected to the discharge port of the roller cutter 4 for initial screening of the fibers cut by the roller cutter 4. The small particle outlet of the first vibrating screen 5 is connected to the second vibrating screen 7 via the second conveying device 6. The second conveying device 6 is used to transport the small particle fibers screened by the first vibrating screen 5 to the second vibrating screen 7 for further screening. The large particle outlet of the first vibrating screen 5 is connected to the vibrating feeder 2 via the third conveying device 8 and the fourth conveying device 9. The third conveying device 8 and the fourth conveying device 9 are used to convey the large particle fibers remaining after screening by the first vibrating screen 5 to the vibrating feeder 2. After being vibrated and dispersed by the vibrating feeder 2, the fibers are conveyed to the roller cutter 4 for further cutting via the first conveying device 3. The small particle outlet of the second vibrating screen 7 is connected to the dryer via the fifth conveying device (not shown in the figure). The fifth conveying device is used to convey the qualified fibers screened by the second vibrating screen 7 to the dryer for drying. The large particle outlet of the second vibrating screen 7 is connected to the vibrating feeder 2 via the third conveying device 8 and the fourth conveying device 9. The third conveying device 8 and the fourth conveying device 9 are used to convey the large particle fibers remaining after screening by the second vibrating screen 7 to the vibrating feeder 2. After being vibrated and dispersed by the vibrating feeder 2, the fibers are conveyed to the roller cutter 4 for further cutting via the first conveying device 3, thereby improving the fineness and uniformity of the glass fiber pulverization.

[0037] like Figure 1-Figure 5 As shown, the cutting machine 1 includes a frame 11, on which a feeding device and a cutting device are provided. The cutting device includes a cutting groove and a cutting member 12. A first passage for fiber passage is formed between the cutting groove and the cutting member 12, and the feeding device is flush with the first passage. A first rotating arm 13 is hingedly connected at both ends of the cutting member 12. The first rotating arm 13 includes a first rotating shaft 131 arranged on the frame 11 along the direction of fiber conveyance. Two clamping plates 132 are hingedly connected to the first rotating shaft 131. The cutting member 12 is hingedly arranged between the two clamping plates 132. Two guide rods 133 are vertically provided on the frame 11, which slide in cooperation with the cutting member 12. A first driving device is provided on the frame 11 for driving the cutting member 12 to slide along the guide rods 133. The first driving device drives the cutting member 12 to move in the vertical direction, thereby engaging or separating with the cutting groove.

[0038] The first drive device includes a drive motor 17, a motor shaft of which is provided with a first pulley, which is connected to a second pulley 18 via a transmission belt, and the second pulley 18 is fixed to a second rotating shaft, which is rotatably mounted on the frame 11. The second rotating shaft is also provided with a small sprocket, which is connected to a large sprocket 136 via a chain, and the large sprocket 136 is fixed to a third rotating shaft, which is rotatably mounted on the frame 11. A drive plate 134 is provided on the third rotating shaft, and a second rotating arm 135 is hingedly connected between the drive plate 134 and the cutting member 12. The second rotating arm 135 is hinged to the drive plate 134 by a hinge shaft, and the hinge shaft is eccentrically arranged with respect to the third rotating shaft, so that the rotation of the third rotating shaft drives the hinge shaft to perform circular motion, thereby driving the end of the second rotating arm 135 connected to the cutting member 12 to move in a vertical direction.

[0039] A guide rod 133 is provided on the frame 11 to guide the movement of the cutting piece 12. The driving plate 134 and the second rotating arm 135 form a crank-connecting rod mechanism, which can drive the cutting piece 12 to reciprocate by continuous rotation of the driving motor 17. The structure is simple, the movement frequency is high, and the cutting efficiency is increased. At the same time, the two first rotating arms 13 play an auxiliary role in the movement of the cutting piece 12, increasing the stability of the cutting piece 12 during the movement and avoiding machine failure.

[0040] The cutting element 12 comprises a blade holder 121 and a blade 122 disposed at the bottom of the blade holder 121. The fiber cutting process is accomplished by the engagement of the blade 122 with the cutting groove. A pressing device for compressing the fiber is provided on the side of the blade holder 121 facing the cutting device. During the fiber cutting process, the pressing device compresses the fiber, increasing cutting accuracy.

[0041] The pressing device includes a follower plate 123 mounted on the blade holder 121. The length of the follower plate 123 is shorter than that of the blade holder 121, allowing the first rotating arm 13 to be mounted on the blade holder 121, effectively utilizing the space. The guide rod 133 slidably engages with the follower plate 123, guiding the movement of the cutting element 12 while limiting the direction of movement of the cutting element 12. A pressing plate 124 is provided below the follower plate 123. A spring 125 is stretched between the pressing plate 124 and the follower plate 123. Accordingly, a support plate is provided below the pressing plate 124. A third channel for the passage of fibers is formed between the pressing plate 124 and the support plate. The first channel and the third channel are aligned, allowing fibers to pass through sequentially.

[0042] In its natural state, the spring 125 is stretched, and the bottom end of the pressing plate 124 is located at a lower level than the bottom end of the blade 122. During use, the knife holder 121 drives the follower plate 123 to move downward, so that the pressing plate 124 preferentially contacts the fiber and thereby compresses the fiber. The knife holder 121 continues to move downward, and the spring 125 contracts, and the pressing plate 124 continues to compress the fiber until the blade 122 engages with the cutting groove, completing the fiber cutting. The knife holder 121 drives the follower plate 123 to move upward, and the blade 122 separates from the cutting groove. After the spring 125 returns to its original stretched length, it drives the pressing plate 124 to move upward, preparing for the next cutting.

[0043] An auxiliary rod 126 extends upward from the press plate 124. A through hole is provided at a position corresponding to the auxiliary rod 126 on the follower plate 123. The auxiliary rod 126 is inserted into the through hole, and a spring 125 is sleeved on the outer circumference of the auxiliary rod 126. The auxiliary rod 126 guides the deformation of the spring 125, ensuring that the spring 125 expands and contracts in the vertical direction, thereby driving the press plate 124 to move.

[0044] The splint 132 is hinged on both sides of the knife seat 121 to increase the stability of the movement of the knife seat 121, and the second rotating arm 135 is rotatably set on the knife seat 121 to effectively utilize the space. A mounting groove 127 is provided at the connection between the knife seat 121 and the second rotating arm 135, and the second rotating arm 135 is hingedly set in the mounting groove 127, which reduces the space occupied and thereby reduces the volume of the entire equipment.

[0045] The feeding device includes a conveyor device 14 and a pressure roller device 15. The conveyor device 14 includes a conveyor belt 141 for conveying fibers and a roller 142 for rotating the conveyor belt 141. The pressure roller device 15 includes an upper pressure roller 151 and a lower pressure roller 152, forming a second channel for fibers to pass through. The frame 1 is provided with a second drive device for rotating the conveyor device 14 and the pressure roller device 15. The first channel, the second channel, and the top of the conveyor belt 141 are flush, ensuring that the fibers move along the discharge port of the frame 11.

[0046] The second drive device includes a servo motor 16 mounted on the frame 11. A driving gear is mounted on the output shaft of the servo motor 16. A first driven gear 1523 is mounted on one end of the lower pressure roller 152, and a second driven gear 1421 is mounted on one end of the roller 142. Both the first driven gear 1523 and the second driven gear 1421 mesh with the driving gear. A first gear 1522 is mounted on the end of the lower pressure roller 152 remote from the first driven gear 1523. A second gear 1512 is mounted on one end of the upper pressure roller 151, meshing with the first gear 1522. By providing a single servo motor 16, the conveyor belt 141 and the lower pressure roller 152 can be rotated synchronously, reducing equipment costs. Furthermore, the lower pressure roller 152 and the upper pressure roller 151 are meshed with each other via the first gear 1522 and the second gear 1512, enabling synchronous rotation of the upper and lower pressure rollers 151 and 152, increasing fiber conveying efficiency and facilitating fiber compaction.

[0047] The frame 11 is symmetrically provided with two chute slots 111 along the length of the pressing roller assembly 15. The chute slots 111 are arranged vertically. The lower pressing roller 152 is provided with a lower slider 1524 that slidably engages with the chute slots 111. The lower slider 1524 is connected to the first gear 1522 via a first universal joint 1521. In its natural state, the lower slider 1524 rests on the bottom end of the chute slots 111. The upper pressing roller 151 is provided with an upper slider 1513 that slidably engages with the chute slots 111. The upper slider 1513 is connected to the second gear 511 via a second universal joint 1511. This design allows the upper pressing roller 151 to move vertically to accommodate fibers of varying thicknesses. Furthermore, the second universal joint 1511 ensures that the first gear 1522 and the second gear 1512 are continuously engaged during movement of the upper pressing roller 151, allowing the upper pressing roller 151 to rotate synchronously with the lower pressing roller 152.

[0048] A first notch is provided at one end of the second universal joint 1511 connected to the upper pressure roller 151. The first notch is opened in the vertical direction, and a first stop bar is horizontally provided at the end of the first notch. A second notch is provided on the upper pressure roller 151. The second notch is opened in the horizontal direction, and a second stop bar is vertically provided at the end of the second notch. The first stop bar and the second stop bar are respectively inserted into the second notch and the first notch, so that the second universal joint 1511 and the upper pressure roller 151 can swing in the horizontal and vertical directions. At the same time, the first stop bar and the second stop bar can slide in the second notch and the first notch respectively along the length direction of the upper pressure roller 151, providing space for the movement of the upper pressure roller 151. Similarly, this design method can also be used to achieve a universal connection between the lower pressure roller 152 and the first universal joint 1521. It is worth noting that, during the movement of the upper pressing roller 151 , it is ensured that the second universal joint 1511 and the upper pressing roller 151 slide in the horizontal direction to avoid the first gear 1522 and the second gear 1512 being separated.

[0049] An adjustment device is connected to the upper slider 1513 for adjusting the position of the upper slider 1513 within the chute 111. The adjustment device allows the position of the upper pressing roller 151 to be adjusted, thereby varying the size of the second channel to accommodate fiber materials of varying thicknesses. The adjustment device fixes the position of the upper slider 1513, thereby maintaining a fixed size for the second channel. The adjustment device also adjusts the range of movement of the upper pressing roller 151, thereby controlling the range of variation of the second channel.

[0050] The adjustment device includes an adjustment rod 112 vertically disposed above an upper slider 1513. A sleeve 113 is sleeved around the outer periphery of the adjustment rod 112, which is threadedly connected to the sleeve 113. The sleeve 113 is rotatably mounted on the frame 1. Because the adjustment rod 112 is mounted on the upper slider 1513, the upper slider 1513 limits the axial freedom of the adjustment rod 112. Therefore, when the sleeve 113 rotates, it drives the adjustment rod 112 to move vertically, thereby changing the vertical position of the upper slider 1513. Specifically, a motor can be mounted on the frame 11, with the motor's output shaft positioned vertically downward. The rotation of the motor drives the sleeve 113 to rotate, resulting in a simple structure and easy adjustment.

[0051] like Figure 1 and Figure 6 As shown, the vibrating feeder 2 includes a bracket base 21, and a shock-absorbing pad is provided at the bottom of the bracket base 21. The shock-absorbing pad is used to increase the stability of the bracket base 21 and reduce the vibration of the bracket base 21. The top of the bracket base 21 is connected to the feeding hopper 22 through a shock-absorbing spring 23.

[0052] The feed hopper 22 includes a feed plate 221 and side plates 222 and a rear plate 223 connected to the feed plate 221. A vibration motor 24 is provided on both side plates 222. The vibration motor 24 is used to drive the feed hopper 22 to vibrate, vibrate and disperse the fibers in the feed hopper 22, and drive the fibers in the feed hopper 22 to move forward.

[0053] The feed plate 221 is provided with a plurality of spacers 2211, which are used to improve the dispersion of the fibers in the feed hopper 22. One end of the feed hopper 22 is connected to the discharge port of the cutter 1, and the other end of the feed hopper 22 is provided with a discharge opening 224. The fibers dispersed by the vibration feeder 2 are fed into the first conveying device 3 through the discharge opening 224.

[0054] like Figure 1 and Figure 7As shown, the first conveying device 3 includes a frame 31, with a conveying platform 32 disposed above the frame 31. Slots are provided at both ends of the conveying platform 32. A driving roller 34 is rotatably mounted in one of the slots, and a driven roller 35 is rotatably mounted in the other slot. A conveyor belt 33 is connected between the driving roller 34 and the driven roller 35. The conveyor belt 33 has a certain inclination angle. A fixed seat 322 is provided at the bottom of the conveying platform 32. The fixed seat 322 is provided with a driving device for driving the driving roller 34 to rotate. The driving device includes a motor 36. A first sprocket 37 is provided on the motor shaft of the motor 36. A second sprocket 39 is provided at one end of the driving roller 34. The first sprocket 37 is connected to the second sprocket 39 via a chain 38. When the motor 36 is started, the driving roller 34 can be driven to rotate, and the driving roller 37 drives the conveyor belt 33 to move, thereby conveying the fiber to the roller cutter 4.

[0055] There are lifting ears 321 on both sides of the bottom of the conveyor platform 32. There are four lifting ears 321, and the four lifting ears 321 are symmetrically arranged in pairs. A U-shaped groove 3211 is provided on the lifting ears 321, and a threaded hole matching the U-shaped groove 3211 is provided on the frame 31. The fixing piece 311 passes through the U-shaped groove 3211 of the lifting ear 321 and is screwed into the threaded hole of the frame 31 to connect and fix the lifting ear 321 to the frame 31. When the inclination angle of the conveyor belt 33 needs to be adjusted, the fixing piece 311 can be loosened to adjust it, saving time and effort.

[0056] like Figure 1 and Figure 8 As shown, the roller cutter 4 includes a frame 41, on which a knife roller 42 is rotatably mounted. A rubber roller 43 is provided on one side of the knife roller 42. The rubber roller 43 is provided on the frame 41 and cooperates with the knife roller 42.

[0057] The drive device includes a cutter roller motor 44, a first pulley 45 is provided on the motor shaft of the cutter roller motor 44, and a second pulley 47 is provided on the cutter roller shaft of the cutter roller 42. The first pulley 45 is connected to the second pulley 47 via a transmission belt 46.

[0058] The frame 41 is also provided with a tightening mechanism 48 for tightening the rubber roller 43 against the knife roller 42. The tightening mechanism 48 includes a threaded rod 481 and a lock nut 483 that is threadedly engaged with the threaded rod 481. The frame 41 is provided with a through hole that can pass through the threaded rod 481. During installation, the threaded rod 481 is passed through the through hole of the frame 41 and pressed against the rubber roller shaft of the rubber roller 43, and then the lock nut 483 is tightened. For ease of operation, a rotating wheel 482 is provided at the end of the threaded rod 481.

[0059] The knife roller 42 includes a roller body 421, with multiple blades 422 disposed on its outer wall.

Specifically, the outer wall of the roller body 421 is provided with multiple axial knife grooves for accommodating the blades 422. The width of the axial knife grooves is greater than the thickness of the blades 422. The two pressure plates 423 are provided with through-holes that pass through the knife roller shaft. During installation, the two pressure plates 423 are respectively mounted on the ends of the roller body 421, thereby securing the blades 422 to the outer wall of the roller body 421.

A small particle outlet 5211 is provided at the bottom of the screen box 521. The large particle fibers intercepted by the coarse-mesh screen 522 and the fine-mesh screen 523 are discharged through the large particle outlet 5212.

[0063] The fibers fall through the discharge port 492 of the roller cutter 4 onto the coarse-mesh screen 522 of the screen box 521. The vibration motor 54 drives the screen box 521 to vibrate, thereby vibrating the coarse-mesh screen 522 and the fine-mesh screen 523 inside the screen box 521. The coarse-mesh screen 522 first screens the fibers, intercepting larger fiber particles. The fine fibers pass through the mesh of the coarse-mesh screen 522 and fall onto the fine-mesh screen 523, where they are screened a second time. The large particles intercepted by the coarse-mesh screen 522 are delivered to the third conveyor 8 through the large particle outlet 5212.

[0064] Fine mesh screen 523 performs a second screening on the fibers screened by coarse mesh screen 522. During screening, fine mesh screen 523 intercepts larger fiber particles, while fine fibers pass through the mesh of fine mesh screen 523 and are delivered to the second conveyor 6 through the small particle outlet 5211. The second conveyor 6 then conveys the fibers screened by the first vibrating screen 5 to the second vibrating screen 7 for further screening. The large particles intercepted by fine mesh screen 523 are delivered to the third conveyor 8 through the large particle outlet 5212.

[0065] The third conveying device 8 conveys the large particle fibers intercepted by the first vibrating screen 5 to the vibrating feeder 2 through the fourth conveying device 9. The fibers remaining after screening by the first vibrating screen 5 are vibrated and dispersed by the vibrating feeder 2, and then sent to the rolling cutter 4 for further cutting through the first conveying device 3.

[0066] The structure of the second vibrating screen 7 of this embodiment is the same as that of the first vibrating screen 5 , and the present invention will not repeat them any further.

[0067] When the second vibrating screen 7 is screening the fiber filaments, the coarse mesh screen of the second vibrating screen 7 first screens the fibers, intercepting larger fiber particles. Fine fibers pass through the mesh of the coarse mesh screen and fall onto the fine mesh screen, where they are screened a second time. The large particles intercepted by the coarse mesh screen are fed to the third conveying device 8 through the large particle outlet.

[0068] The fine mesh screen performs a second screening on the fibers screened by the coarse mesh screen. During the screening process, the fine mesh screen intercepts larger fiber particles. Qualified fibers pass through the mesh of the fine mesh screen and fall onto the fifth conveyor through the small particle outlet. The fifth conveyor then delivers the qualified fibers to the dryer for drying, resulting in finished fibers. The large particles intercepted by the fine mesh screen are delivered to the third conveyor 8 through the large particle outlet.

[0069] The third conveying device 8 conveys the large particle fibers intercepted by the second vibrating screen 7 to the vibrating feeder 2 through the fourth conveying device 9.

[0070] The fibers remaining after screening by the second vibrating screen 7 are vibrated and dispersed by the vibrating feeder 2 and then fed into the rolling cutter 4 through the first conveying device 3 for further cutting.

[0071] The structures of the third conveying device 8 , the fourth conveying device 9 and the fifth conveying device in this embodiment are the same as that of the first conveying device 3 , and the present invention will not elaborate on them any more.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
