Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, and specifically to a continuous feeding device for glass fiber. Background Technology

[0002] Glass fiber is a reinforcing material with advantages such as high temperature resistance and good insulation. Gypsum board is a modern green building material. In order to improve the strength of gypsum board, in the current technology, gypsum slurry and chopped glass fiber are sprayed into a mixing tank at the same time during production.

[0003] Existing glass fiber is fed using a metering reamer, which allows for accurate and relatively stable feeding. However, impurities in the glass fiber, coupled with its inherent strength, can cause the metering reamer to become clogged or break. If the reamer is not repaired promptly, uneven feeding, insufficient feeding, or even no feeding of glass fiber can occur, leading to quality problems in the subsequent gypsum board production. If not addressed in time, this can result in significant damage to a large number of gypsum boards, wasting materials and increasing costs. Furthermore, prolonged downtime can lead to a decrease in gypsum board production. Summary of the Invention

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0041] In the prior art, when the metering reamer fails, it is inconvenient to repair the feeding reamer, which not only affects the uniformity of the glass fiber feeding, leading to poor products of the subsequent gypsum board, but also leads to the problem of the decline of the gypsum board production efficiency.

[0042] As shown in Figure 1 The present application provides a glass fiber continuous feeding device, which comprises a material feeding bin 1, at least two groups of feeding mechanisms for discharging are arranged in the material feeding bin 1, a rotating disc 6 is rotatably installed at the bottom wall in the material feeding bin 1, the feeding ports of the multiple groups of feeding mechanisms are blocked by the rotating disc 6, and a second driving mechanism 8 for driving the rotating disc 6 to rotate is installed on the material feeding bin 1.

[0043] A feeding channel 7 is formed through the rotating disc 6, and the feeding channel 7 is communicated with the multiple groups of feeding mechanisms one by one under the driving of the rotating disc 6.

[0044] In use, the second driving mechanism 8 is started, the rotating disc 6 is driven to rotate by the second driving mechanism 8, the feeding channel 7 on the rotating disc 6 is opposite to the feeding port of one of the groups of feeding mechanisms, the material in the material feeding bin 1 enters the feeding mechanism opposite to it through the feeding channel 7, and is conveyed to the next production process by the feeding mechanism.

[0045] When the discharging mechanism fails, the second driving mechanism 8 is started again, so that the feeding channel 7 on the rotating disc 6 is opposite to the feeding port of another group of discharging mechanisms, and normal discharging work is carried out through another group of discharging mechanisms, so as to maintain the normal discharging of glass fibers, and because there is no mutual connection between the groups of discharging mechanisms, at this time, the staff can maintain and repair the discharging mechanism that fails, and so on, to maintain the continuous operation of the discharging mechanism.

[0046] When the glass fiber enters the discharging mechanism from the feeding channel 7, due to the friction and adhesion between the glass fiber and the inner wall of the feeding channel 7, a dome is easily formed at the feeding channel 7, the feeding channel 7 is blocked, and it is difficult to discharge. Therefore, the following solutions are proposed:

[0047] Referring to Figure 3 and Figure 4 , preferably, the feeding channel 7 is a circular hole channel, an annular groove 10 is formed in the inner wall of the feeding channel 7, a rotating ring 11 is rotatably installed in the annular groove 10, a dome breaking knife 12 is fixedly connected to the inner circle of the rotating ring 11 through a supporting rod, the both ends of the dome breaking knife 12 are wedge-shaped, and the dome breaking knife 12 is always in sliding connection with the inner wall of the feeding channel 7. A power mechanism 13 for driving the rotating ring 11 to rotate is arranged on the material storage bin 1.

[0048] Under the driving of the power mechanism 13, the rotating ring 11 drives the dome breaking knife 12 to rotate to break the material arch formed in the feeding channel 7;

[0049] Among them:

[0050] The vertical central axes of the feeding channel 7, the annular groove 10 and the rotating ring 11 coincide;

[0051] The rotating ring 11 and the groove wall of the annular groove 10 are rotatably connected through a sealing bearing.

[0052] In use, the rotating ring 11 is periodically or continuously driven to rotate by the power mechanism 13, and the dome breaking knife 12 is driven to slide along the inner wall of the feeding channel 7 by the supporting rod, so that the material adhered to the inner wall of the feeding channel 7 can be scraped off by the dome breaking knife 12, the material arch at the feeding channel 7 is avoided, and the smooth discharge of the material in the feeding channel 7 is maintained.

[0053] Referring to Figure 2 , preferably, the power mechanism includes a mounting groove 18 communicated with the annular groove 10 and formed in the rotating disc 6, a driving gear 1302 is rotatably installed in the mounting groove 18 through the rotating shaft 9, a driven gear ring 1301 is fixedly sleeved outside the rotating ring 11, and the driven gear ring 1301 is engaged with the driving gear 1302;

[0054] Among them:

[0055] One end of the rotating shaft 9 extends to the outside of the rotating disc 6 and is connected with the output end of the second driving mechanism 8.

[0056] The rotating shaft 9 is rotationally connected with the rotating disc 6 through the one-way bearing 14.

[0057] In use, when it is needed to drive the rotating disc 6 to rotate to change the selection of the blanking mechanism, the second driving mechanism 8 is opened in the forward direction, the second driving mechanism 8 drives the rotating shaft 9 to rotate in the forward direction, under the action of the one-way bearing 14, the rotating shaft 9 drives the rotating disc 6 to rotate in the one-way direction, so that the feeding channel 7 on the rotating disc 6 is opposite to the feeding port of one of the blanking mechanisms;

[0058] When it is needed to drive the rotating ring 11 to rotate to break the arch in the feeding channel 7, the second driving mechanism 8 is opened in the reverse direction, the second driving mechanism 8 drives the rotating shaft 9 to rotate in the reverse direction, under the action of the one-way bearing 14, the rotating disc 6 remains stationary, the rotating shaft 9 drives the driving gear 1302 to rotate, through the transmission of the driving gear 1302 and the driven gear ring 1301, the rotating shaft 9 drives the rotating ring 11 to rotate, the rotating ring 11 drives the arch-breaking knife 12 to slide relative to the feeding channel 7 through the supporting rod, so as to remove the arch in the feeding channel 7;

[0059] In this way, the driving of the rotating disc 6 and the rotating ring 11 only needs the same power source, that is, the second driving mechanism 8, which can save the occupied space of the equipment, and the driving of the rotating disc 6 and the driving of the rotating ring 11 will not interfere with each other, both of which can work normally.

[0060] During the transportation of glass fibers, static electricity is easily generated by the mutual friction between the glass fibers, therefore, the glass fibers are also easily bonded on the inner wall of the material sliding bin 1, thereby forming a material layer, and the cross-sectional area of the feeding channel 7 only occupies a small part of the total area of the rotating disc 6, when blanking, the material is easily accumulated on the rotating disc 6, and the material on the side of the rotating disc 6 far away from the feeding channel 7 has poor flowability, which causes the material to stagnate on the rotating disc 6, therefore, we propose the following solutions:

[0061] Referring to Figure 1 As shown in the figure, preferably, a guide plate 15 with a wedge-shaped cross section is arranged on the rotating disc 6, and the inclined surface of the guide plate 15 is inclined downward towards the feeding channel 7;

[0062] Through the guide plate 15, the material on the rotating disc 6 can be guided to the feeding channel 7, so as to avoid the accumulation of material on the rotating disc 6.

[0063] As shown in the above, with the rotation of the rotating disc 6, the rotating disc 6 drives the guide plate 15 to slide along the inner wall of the material sliding bin 1, therefore, through the guide plate 15, the material bonded on the inner wall of the material sliding bin 1 can be scraped off, avoiding the formation of a bonded material layer on the inner wall of the material sliding bin 1.

[0064] While the inclined guide plate 15 can guide the material in the chute 1, if the inclination angle of the guide plate 15 is too large, the material in the chute 1 will concentrate at the feed channel 7, resulting in greater material pressure at the feed channel 7, and also requiring an increase in the internal depth of the chute 1. If the inclination angle of the guide plate 15 is too small, the guiding effect of the guide plate 15 will be reduced, and the lower side of the guide plate will form an arch due to the mutual friction between materials. Therefore, we propose the following solutions:

[0065] Reference Figure 1 , Figure 2 and Figure 5 As shown, a scraper 16 is rotatably mounted on the guide plate 15, and a coil spring is provided between the scraper 16 and the guide plate 15. Under the elastic force of the coil spring, the scraper 16 can automatically reset.

[0066] One end of the scraper 16 extends into the feed channel 7 and is connected to the abutment block 17. As the arch-breaking knife 12 rotates, the arch-breaking knife 12 periodically abuts against the abutment block 17. Under the pressure of the arch-breaking knife 12, the scraper 16 slides relative to the guide plate 15 to remove the arch feet on the guide plate 15.

[0067] In use, as the rotating ring 11 drives the arch-breaking knife 12 to rotate, the arch-breaking knife 12 abuts against the block 17. The block 17 drives the scraper 16 to swing on the guide plate 15, thereby removing the material on the guide plate 15. Since the movement trajectory of the arch-breaking knife 12 is circular, after the arch-breaking knife 12 presses against the block 17 for a certain period of time, it gradually moves away from the block 17. After the arch-breaking knife 12 separates from the block 17, the scraper 16 automatically resets under the action of the spring force. This process is repeated to clean the surface of the guide plate 15.

[0068] Furthermore, as needed, a combination of multiple scraper plates 16 and abutment blocks 17 can be provided on the guide plate 15 to expand the coverage of the upper surface of the guide plate 15.

[0069] Reference Figure 7 As shown, preferably, the abutment 17 includes a sleeve 1701 fixedly connected to the scraper plate 16. A movable plate 1703 is elastically connected inside the sleeve 1701 by a spring 1702. The lower end of the movable plate 1703 is a wedge-shaped part, and the wedge-shaped part extends to the bottom of the sleeve 1701.

[0070] In use, the arch-breaking knife 12 first abuts against the sleeve 1701. As the arch-breaking knife 12 moves relative to the sleeve 1701, the arch-breaking knife 12 abuts against the wedge-shaped part on the movable plate 1703. Under the action of the arch-breaking knife 12, the movable plate 1703 compresses the spring 1702 and stores it inside the sleeve 1701. This is to avoid the rigid friction between the arch-breaking knife 12 and the abutment 17, which would cause damage to the abutment 17 and the arch-breaking knife 12.

[0071] Preferably, the discharging mechanism comprises a discharging channel 2 formed in the bottom wall of the discharging bin 1, a discharging reamer 4 rotatably installed in the discharging channel 2, and a first driving mechanism 5 installed on the discharging bin 1 and configured to drive the discharging reamer 4.

[0072] The discharging end of the discharging channel 2 is connected to the feeding end of the next production process, and a flow monitor is arranged at the discharging end of the discharging channel 2 to monitor the discharging amount. The flow monitor is configured to monitor whether the discharging amount of the discharging channel 2 is stable, and to determine whether the corresponding discharging mechanism is malfunctioning. When the corresponding discharging mechanism is malfunctioning, the flow monitor actively sends a warning signal to the outside.

[0073] Referring to Figure 6 Preferably, each discharging channel 2 is provided with an access hole between the side wall of the discharging bin 1 and the discharging channel 2, and each access hole is detachably provided with an access door 3. The side surface of the access door 3 is provided with an arc surface matched with the inner wall of the discharging channel 2.

[0074] The access door 3 allows the worker to conveniently repair the malfunctioning discharging mechanism.

[0075] Preferably, the rotating disc 6 is rotatably connected to the inner wall of the discharging bin 1 through a damping bearing to increase the friction between the rotating disc 6 and the inner wall of the discharging bin 1, so as to avoid the displacement of the rotating disc 6 under the influence of external vibration and the misalignment between the feeding channel 7 and the discharging mechanism.

[0076] The guide plate 15 is slidably connected to the inner wall of the discharging bin 1. Under the driving of the rotating disc 6, the guide plate 15 slides along the inner wall of the discharging bin 1 to remove the material layer adhered to the inner wall of the discharging bin 1.
