Description

Technical Field

[0001] This utility model relates to the field of industrial production equipment technology, and in particular to a calcium silicate board production device. Background Technology

[0002] In the current domestic production of fiber-reinforced calcium silicate boards using the headstock method, production efficiency is generally improved by increasing the speed of the felt and raising the height of the headbox outlet (to increase the thickness of a single layer of material). However, increasing the felt speed can lead to excessive speed differences when the slurry is spread evenly on the felt, resulting in a decrease in the longitudinal and transverse strength ratio of the final board. On the other hand, raising the headbox height results in an excessively thick single layer of material, which can lead to uneven thickness of the material layers during the process and also decrease the longitudinal and transverse strength ratio of the final board. Utility Model Content

[0003] The main purpose of this invention is to propose a calcium silicate board production device, which aims to solve the problems of uneven material layer thickness and decreased longitudinal and transverse strength ratio of the finished board in existing flow-process fiber reinforced calcium silicate board production equipment.

[0004] To achieve the above objectives, this utility model proposes a calcium silicate board production apparatus, comprising a frame, a headbox, a driven roller assembly, a vibrating mechanism, and a slurry storage belt. The headbox and the driven roller assembly are both mounted on the frame. The driven roller assembly includes a first steering roller, which is located on the discharge side of the headbox and below the headbox's slurry outlet. The slurry storage belt is wound around the first steering roller. The vibrating mechanism is driven to the first steering roller, and the first steering roller is driven by the vibrating mechanism to reciprocate axially.

[0005] According to some embodiments of the present invention, the rocking mechanism includes a first motor, an eccentric wheel, and a transmission assembly, wherein the output shaft of the first motor and the first steering roller are connected to the transmission assembly via the eccentric wheel.

The first bearing housing is fixed on the elastic component. The inner ring of the first bearing housing is connected to one end of the first steering roller spindle.

[0007] According to some embodiments of the present invention, it further includes an active roller and a forming roller cylinder for adsorbing slurry on the slurry storage belt and extruding and stacking it to form a blank. The active roller and the first deflecting roller are connected through the slurry storage belt, and the active roller and the forming roller cylinder cooperate to form a discharge groove for the slurry storage belt to pass through and scrape off the slurry. The forming roller cylinder has a slit on the side facing the active roller, and a blank cutting member is provided inside the forming roller cylinder. The blank cutting member moves in the vertical direction relative to the forming roller cylinder and extends out from the slit.

[0008] According to some embodiments of the present invention, a material layer cutting assembly is also provided on the frame. The material layer cutting assembly includes a second motor and a cutting baffle connected to the output shaft of the second motor. The cutting baffle is located above the slurry storage belt and rotates along the axial direction of the output shaft of the second motor and contacts the slurry storage belt.

[0009] According to some embodiments of the present invention, it further includes an alignment assembly disposed on the frame. The alignment assembly includes a second bearing housing and two retractable and expandable adjusting airbags. The driven roller assembly also includes a second steering roller. The driving roller, the first steering roller, and the second steering roller are sequentially connected through the slurry storage belt. One end of the spindle of the second steering roller is connected to the second bearing housing. The two adjusting airbags are respectively disposed on both sides of the second bearing housing in the length direction of the frame. The second bearing housing is adjustable and movable in the length direction of the frame by the drive of the two adjusting airbags.

[0010] According to some embodiments of the present invention, the driven roller assembly includes a third steering roller and a fourth steering roller, the fourth steering roller being disposed above the third steering roller, the driving roller, the fourth steering roller, the third steering roller and the first steering roller being sequentially connected via the slurry storage belt, and the third steering roller being adjustable and movable in the length direction of the frame.

[0011] According to some embodiments of the present invention, a cleaning nozzle is also included for cleaning the slurry storage belt after the slurry is scraped off. The cleaning nozzle is disposed on the frame and faces the slurry storage surface of the slurry storage belt.

[0012] According to some embodiments of the present invention, the driven roller assembly further includes a fifth steering roller and a sixth steering roller, the driving roller, the fifth steering roller, the sixth steering roller and the first steering roller are connected in sequence through the slurry storage belt, and the cleaning nozzle is located between the fifth steering roller and the sixth steering roller.

[0013] According to some embodiments of the present invention, the frame is provided with a natural dewatering station and a vacuum dewatering station. The natural dewatering station and the vacuum dewatering station are both located between the first steering roller and the forming roller, and are sequentially arranged on the movement path of the slurry during the movement of the slurry from the first steering roller to the forming roller.

[0014] This utility model has at least the following beneficial effects:

[0015] In this invention, the slurry storage belt first passes through the first steering roller and receives the slurry flowing from the slurry outlet of the headbox. Driven by the vibration mechanism, the first steering roller reciprocates axially, causing the slurry storage belt to vibrate axially. This causes the slurry flowing on the storage belt to vibrate synchronously. On one hand, the vibration forms a uniformly thick slurry layer; on the other hand, it improves the internal fiber arrangement, thus mitigating the decrease in the longitudinal and transverse modulus of the final board. The slurry storage belt then moves to the equipment for subsequent production processes. The calcium silicate board production apparatus provided by this invention solves the problems of uneven slurry layer thickness and decreased longitudinal and transverse modulus of the finished board in existing flow-type calcium silicate board production equipment.

[0028] This utility model provides a calcium silicate board production device. Figures 1 to 6 This invention provides a specific embodiment of a calcium silicate board production apparatus.

[0029] like Figures 1 to 3 As shown, this utility model embodiment provides a calcium silicate board production apparatus 100, including a frame 1, a headbox 2, a driven roller assembly 3, a shaking mechanism 4, and a slurry storage belt 5. The headbox 2 and the driven roller assembly 3 are both mounted on the frame 1. The driven roller assembly 3 includes a first steering roller 31, which is located on the discharge side of the headbox 2 and below the headbox 2's slurry outlet 21. The slurry storage belt 5 is wound around the first steering roller 31. The shaking mechanism 4 is driven to the first steering roller 31, and the first steering roller 31 is driven by the shaking mechanism 4 to reciprocate in the axial direction of the first steering roller 31.

[0030] In this invention, the slurry storage belt 5 first passes through the first steering roller 31 and receives the slurry flowing from the slurry outlet 21 of the headbox 2. Driven by the vibration mechanism 4, the first steering roller 31 can reciprocate axially, causing the slurry storage belt 5 to vibrate axially. This causes the slurry flowing on the slurry storage belt 5 to vibrate synchronously. On the one hand, the slurry forms a uniformly thick layer under vibration; on the other hand, the vibration improves the internal fiber arrangement, thus reducing the decrease in the longitudinal and transverse modulus of the final board. Then, the slurry storage belt 5 moves to the equipment for subsequent production processes. The calcium silicate board production device 100 provided by this invention solves the problems of uneven slurry layer thickness and decreased longitudinal and transverse modulus of the finished board in existing flow-type calcium silicate board production equipment.

[0031] Specifically, the slurry storage belt 5 can be a blanket or other components with strong slurry storage capacity known to those skilled in the art.

[0032] It should be noted that the headbox 2 can be replaced by a shotcrete box.

[0033] The specific structure of the rocking mechanism 4 is not limited, as long as the first steering roller 31 is driven by the rocking mechanism 4 to reciprocate in the axial direction of the first steering roller 31. For example, in some embodiments, such as... Figure 3 As shown, the rocking mechanism 4 includes a first motor 41, an eccentric wheel 42, and a transmission assembly 43. The output shaft of the first motor 41 and the first steering roller 31 are connected to the transmission assembly 43 via the eccentric wheel 42. With this configuration, the rotation of the output shaft of the first motor 41 can be converted into reciprocating motion in the horizontal direction through the cooperation of the eccentric wheel 42 and the transmission assembly 43, thereby enabling the first steering roller 31 to reciprocate along its axial direction.

[0034] Furthermore, in some embodiments, such as Figure 3 As shown, the transmission assembly 43 includes a transmission component 431, a connecting component 432, an elastic component 433, and a first bearing seat 434. The output shaft of the first motor 41 is connected to the transmission component 431 through the eccentric wheel 42. The transmission component 431 is connected to the elastic component 433 through the connecting component 432. The first bearing seat 434 is fixed on the elastic component 433. The inner ring of the first bearing seat 434 is connected to one end of the spindle of the first steering roller 31. Specifically, one end of the transmission member 431 is rotatably connected to the eccentric wheel 42, and the other end is rotatably connected to the connecting member 432. The output shaft of the first motor 41 outputs a horizontal force to the connecting member 432 through the eccentric wheel 42 and the transmission member 431 and transmits it to the elastic member 433, causing the elastic member 433 to undergo reciprocating deformation in the horizontal direction and generate vibration. Since the first bearing seat 434 is connected to the elastic member 433, the elastic member 433 can transmit the vibration to the first steering roller 31 through the first bearing seat 434, causing the first steering roller 31 to reciprocate in its axial direction.

[0035] Specifically, the first motor 41 is a geared motor, and the elastic element 433 is a leaf spring.

[0036] In some embodiments, such as Figure 1 and Figure 5As shown, the calcium silicate board production apparatus 100 further includes a drive roller 6 and a forming roller cylinder 7 for adsorbing the slurry on the slurry storage belt 5 and extruding and stacking it to form a blank. The drive roller 6 and the first steering roller 31 are connected through the slurry storage belt 5, and the drive roller 6 and the forming roller cylinder 7 cooperate to form a discharge groove through which the slurry storage belt 5 passes and scrapes off the slurry. The forming roller cylinder 7 has a slit on the side facing the drive roller 6, and a blank cutting member 71 is provided inside the forming roller cylinder 7. The blank cutting member 71 moves in the vertical direction relative to the forming roller cylinder 7 and extends out from the slit. After the outer surface of the forming roller 7 adsorbs multiple layers of material and is extruded and stacked to form a blank of a certain thickness, the blank needs to be removed from the forming roller 7 to form a slab and output to the next process. When the forming roller 7 needs to rotate to adsorb slurry, the blank cutting member 71 moves upward and retracts from the cut to avoid affecting the rotation of the forming roller 7. When the blank reaches a certain thickness, the blank cutting member 71 moves downward and extends from the cut to cut the blank, so that the blank is separated from the forming roller 7, and the curved section of the blank straightens under its own gravity to form a slab.

[0037] Specifically, a thickness detection unit is provided above the forming roller cylinder 7. The thickness of the blank is detected by the thickness detection unit. When the blank reaches the preset thickness, the blank cutting member 71 is controlled to move downward to cut the blank.

[0038] To reduce the difficulty of cutting the billet, in some embodiments, such as Figure 6 As shown, the calcium silicate board production apparatus 100 further includes a material layer cutting assembly 8 disposed on the frame 1. The material layer cutting assembly 8 includes a second motor 81 and a cutting baffle 82 connected to the output shaft of the second motor 81. The cutting baffle 82 is located above the slurry storage belt 5 and rotates along the axial direction of the output shaft of the second motor 81 and contacts the slurry storage belt 5. With this configuration, the cutting baffle 82 is driven by the second motor 81 to contact the slurry storage belt 5 to cut the material layer in advance. This allows the blank cutting component 71 to extend only a small distance from the cut to cut the blank attached to the forming roller cylinder 7. This reduces the difficulty of blank cutting and avoids damage to the slurry storage belt 5 caused by the blank cutting component 71 cutting the material layer on the slurry storage belt 5.

[0039] Because the slurry received by the slurry storage belt 5 from the slurry outlet 21 has a high water content, the forming roller 7 has difficulty adsorbing the material layer. Therefore, in some embodiments, such as Figure 1As shown, the frame 1 is provided with a natural dewatering station 11 and a vacuum dewatering station 12. Both the natural dewatering station 11 and the vacuum dewatering station 12 are located between the first steering roller 31 and the forming roller 7, and are sequentially arranged along the movement path of the slurry during its movement from the first steering roller 31 to the forming roller 7. Specifically, the natural dewatering station 11 is provided with a water receiving trough, and the vacuum dewatering station 12 is provided with multiple vacuum boxes spaced apart along the length of the frame 1. The water receiving trough and the multiple vacuum boxes are located below the slurry storage belt 5. After receiving the slurry at the first steering roller 31, the slurry storage belt 5 first passes through the natural dewatering station 11, where the water in the slurry drips into the water receiving trough under its own gravity. Then, the slurry storage belt 5 moves to the vacuum dewatering station 12, where the multiple vacuum boxes use negative pressure to absorb excess water from the material layer attached to the slurry storage belt 5, forming a material layer with suitable moisture content.

[0040] It should be noted that, due to the arrangement of the natural dewatering station 11 and the vacuum dewatering station 12 between the first steering roller 31 and the drive roller 6, a relatively long distance exists between them. When the slurry storage belt 5 moves from the first steering roller 31 to the drive roller 6 in the upper space of the frame 1, it can be supported by the water receiving tank and the multiple vacuum boxes. However, when the slurry storage belt 5 moves back from the drive roller 6 in the lower space of the frame 1, it may sag due to lack of support. Therefore, if... Figure 1 As shown, the lower layer of the frame 1 is provided with a plurality of support rollers 37 spaced apart along its length to support the slurry storage belt 5.

[0041] Because the first steering roller 31 reciprocates in its axial direction, driving the slurry storage belt 5 to reciprocate, it may cause the slurry storage belt 5 to shift horizontally, making the centerline of the slurry storage belt 5 inconsistent with the centerline of the frame 1. This cumulative shift will eventually cause the slurry storage belt 5 to detach from the frame 1. Therefore, in some embodiments, such as... Figure 4 and Figure 6As shown, the calcium silicate board production apparatus 100 further includes an alignment component 9 disposed on the frame 1. The alignment component 9 includes a second bearing seat 91 and two retractable and expandable adjusting airbags 92. The driven roller assembly 3 also includes a second steering roller 32. The driving roller 6, the first steering roller 31 and the second steering roller 32 are connected in sequence through the slurry storage belt 5. One end of the spindle of the second steering roller 32 is connected to the second bearing seat 91. The two adjusting airbags 92 are respectively disposed on both sides of the second bearing seat 91 in the length direction of the frame 1. The second bearing seat 91 is adjustable and movable in the length direction of the frame 1 by the drive of the two adjusting airbags 92. With this configuration, the position of the second bearing seat 91 in the length direction of the frame 1 is adjusted by the contraction of one of the regulating airbags 92 and the expansion of the other regulating airbag 92. This adjusts the position of one end of the second steering roller 32 while keeping the position of the other end of the second steering roller 32 unchanged, causing the axis of the second steering roller 32 to deflect at an angle in the horizontal direction. This, in turn, adjusts the movement direction of the slurry storage belt 5 passing through the second steering roller 32, so that the centerline of the slurry storage belt 5 is aligned with the centerline of the frame 1.

[0042] In order to adjust the tightness of the slurry storage belt 5, in some embodiments, such as Figure 1 As shown, the driven roller assembly 3 includes a third steering roller 33 and a fourth steering roller 34. The fourth steering roller 34 is positioned above the third steering roller 33. The driving roller 6, the fourth steering roller 34, the third steering roller 33, and the first steering roller 31 are sequentially connected via the slurry storage belt 5. The third steering roller 33 is adjustable in the length direction of the frame 1. With this configuration, when it is necessary to tighten the slurry storage belt 5, the third steering roller 33 moves away from the first steering roller 31 and is positioned; when it is necessary to loosen the slurry storage belt 5, the third steering roller 33 moves closer to the first steering roller 31 and is positioned, thereby adjusting the tension of the slurry storage belt 5.

[0043] Specifically, the frame 1 is provided with a guide structure that extends along the length of the frame 1. A slider is movably mounted on the guide structure and is connected to the third steering roller 33. By driving the slider to move on the guide structure, the third steering roller 33 can be adjusted and moved along the length of the frame 1.

[0044] After the forming roller 7 absorbs the slurry, some slurry remains on the slurry storage belt 5. The slurry dries as the slurry storage belt 5 moves back to the first deflecting roller 31, causing a decrease in the slurry storage capacity of the slurry storage belt 5. Therefore, in some embodiments, such as... Figure 4 As shown, the calcium silicate board production apparatus 100 further includes a cleaning nozzle 10 for cleaning the slurry storage belt 5 after the slurry is scraped off. The cleaning nozzle 10 is mounted on the frame 1 and faces the slurry storage surface of the slurry storage belt 5. This arrangement allows the cleaning fluid sprayed from the cleaning nozzle 10 to clean the slurry storage belt 5, removing residual slurry and preventing a decrease in the slurry storage capacity of the slurry storage belt 5.

[0045] The slurry storage belt 5, after cleaning, contains a large amount of water, which will dilute the slurry. Therefore, in some embodiments, such as... Figure 4 As shown, an upper squeezing roller 38 and a lower squeezing roller 39 are provided between the cleaning nozzle 10 and the first steering roller 31. The upper squeezing roller 38 and the lower squeezing roller 39 are close to each other to form a squeezing groove through which the cleaned slurry storage belt 5 passes to squeeze out the water. With this arrangement, the water in the slurry storage belt 5 is squeezed out by the squeezing groove, thereby improving the slurry storage capacity of the slurry storage belt 5.

[0046] Since the slurry storage belt 5 is positioned downwards after passing the drive roller 6, if the cleaning nozzle 10 is positioned upwards to spray cleaning liquid onto the slurry storage surface, residual slurry and cleaning liquid will flow into the cleaning nozzle 10, causing contamination. Therefore, in some embodiments, such as... Figure 4 As shown, the driven roller assembly 3 further includes a fifth steering roller 35 and a sixth steering roller 36. The driving roller 6, the fifth steering roller 35, the sixth steering roller 36, and the first steering roller 31 are sequentially connected via the slurry storage belt 5. The cleaning nozzle 10 is located between the fifth steering roller 35 and the sixth steering roller 36. This arrangement, through the cooperation of the fifth steering roller 35 and the sixth steering roller 36, adjusts the orientation of the slurry storage surface, preventing residual slurry and cleaning fluid from flowing into the cleaning nozzle 10, and also adapting to different installation positions of the cleaning nozzle 10.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
