Description

Technical Field

[0001] The invention relates to the field of acrylic plate manufacturing, and in particular to a material balancing device for acrylic plate production. Background Art

[0002] Acrylic casting plate is generally formed by injecting slurry into the forming tank through a casting pipe and then solidifying it. The discharge port of the feed pipe is installed in the casting pipe, and the casting pipe injects slurry into the forming tank. Then the slurry leaves the casting pipe and falls into the forming tank, and diffuses and flows in the forming tank to cover the entire forming tank. After that, it solidifies and forms an acrylic casting plate.

[0003] Since the slurry itself solidifies and solidifies relatively quickly during the production process of acrylic cast plates, in order to ensure the uniform thickness of the produced acrylic cast plates and guarantee product quality, it is necessary to design a material distribution device that can improve the diffusion efficiency of the slurry on the forming tank, so as to achieve the purpose of evenly covering the entire forming tank with the slurry before solidification. Summary of the Invention

[0004] In order to improve the diffusion efficiency of the slurry on the forming tank and achieve the purpose of evenly covering the entire forming tank with the slurry before solidification, the present invention provides a material leveling device for acrylic board production.

[0005] The technical solution of the present invention is achieved as follows:

[0006] A material distribution device for acrylic board production includes a forming trough and a pouring pipe mounted above the forming trough, and also includes a slurry distribution pipe. The top of the slurry distribution pipe is installed at the bottom of the pouring pipe. The bottom of the slurry distribution pipe is provided with a slurry distribution head. The inner cavity of the slurry distribution head is connected to the inner cavity of the slurry distribution pipe. The bottom wall of the slurry distribution head is provided with a plurality of slurry outlet holes connected to the inner cavity of the slurry distribution head. The central axes of the plurality of slurry outlet holes are radially distributed on the bottom wall of the slurry distribution head. When the slurry is poured, the slurry enters the pouring pipe through the feeding pipe. In the slurry distribution pipe at the bottom, since there is a slurry distribution head at the bottom of the slurry distribution pipe and a number of slurry outlet holes are provided on the bottom wall of the slurry distribution head, the slurry passes through the inner cavity of the slurry distribution pipe and leaves the slurry distribution pipe through the slurry outlet holes on the slurry distribution head. Since the central axis of the slurry outlet holes is radially distributed, the slurry will be sprayed out of the slurry distribution head in a radial form when passing through the slurry outlet holes. Compared with the traditional vertical falling method, the slurry sprayed out in a radial form plays a role in expanding the slurry pouring range, so as to achieve the purpose of improving the diffusion efficiency of the slurry on the forming trough.

[0007] Furthermore, the bottom wall of the slurry distributing head is spherical, and several slurry outlet holes are evenly distributed on the bottom wall of the slurry distributing head. The central axes of several slurry outlet holes pass through the center of the spherical bottom wall of the slurry distributing head. When pouring, the slurry will be sprayed out of the slurry distributing head in a radial form when passing through the slurry outlet holes, thereby achieving the purpose of expanding the pouring range.

[0008] Furthermore, an internal thread is provided on the top inner wall of the slurry distribution pipe, an external thread is provided on the outer wall of the pouring pipe, and the slurry distribution pipe is threadedly connected to the pouring pipe.

[0009] Furthermore, it also includes a homogenizer plate, which is arranged between the pouring pipe and the forming trough. The homogenizer plate is provided with a number of through holes, and the through holes are distributed in a lattice shape on the homogenizer plate. The slurry passes through the slurry outlet holes on the slurry distributor head and is sprayed onto the homogenizer plate. Since the homogenizer plate has through holes distributed in a lattice shape, part of the slurry sprayed from the slurry distributor head will directly pass through the through holes and fall onto the forming trough, and then diffuse to other places in the forming trough through natural flow, while the remaining slurry will first fall onto the homogenizer plate and flow on the homogenizer plate. When the slurry on the homogenizer plate passes through these through holes, it will fall directly from the through holes to the forming trough. The blocking and diverting effect of the homogenizer plate on the slurry plays a role in secondary expansion of the casting range, which can further improve the diffusion efficiency.

[0010] Furthermore, the homogenizing plate is provided with a plurality of protrusions, which are distributed in a lattice shape on the homogenizing plate, and any one of the protrusions is located between four adjacent through holes, and the protrusion is hemispherical.

[0011] Furthermore, vertical poles are provided on both sides of the forming trough, and the homogenizing plate is movably installed between the two vertical poles. When performing the pouring operation, it is only necessary to provide the homogenizing plate with a driving force for reciprocating movement, thereby achieving the purpose of vibrating the homogenizing plate and improving the diffusion efficiency of the slurry on the homogenizing plate.

[0012] Furthermore, a bottom frame is provided between the two vertical rods, and a slide rail is provided on the bottom frame, and the homogenizing plate is slidably arranged on the bottom frame through the slide rail, wherein the slide rail is arranged along the length or width direction of the bottom frame. In this embodiment, the slide rail is arranged along the length direction of the bottom frame, and the homogenizing plate is slidably arranged on the bottom frame. It is only necessary to apply a reciprocating driving force to the homogenizing plate in the sliding direction of the slide rail so that the homogenizing plate can reciprocate on the slide rail, thereby playing the role of reciprocating vibration of the homogenizing plate left and right. In this way, the slurry falling onto the homogenizing plate will undoubtedly be quickly diffused on the homogenizing plate. The purpose of flow is that when the slurry diffuses and flows rapidly on the homogenizing plate, the slurry will fall directly from the through-hole to the forming tank when passing through the through-hole. Since the through-holes are distributed in a lattice shape on the homogenizing plate, the slurry can be poured into the forming tank in the form of a plane lattice through the reciprocating vibration of the homogenizing plate during the pouring of the slurry. Compared with the vertical direct pouring method, the plane lattice pouring method undoubtedly greatly improves the diffusion efficiency of the slurry and reduces the time it takes for the slurry to fill the forming tank through natural flow, which is conducive to the formation of acrylic sheets with uniform thickness.

[0013] Furthermore, a slider is provided at the bottom of the homogenizing plate, and the slider is slidably connected to the slide rail. A vibration cylinder is provided on the bottom frame, and a piston rod of the vibration cylinder is connected to the homogenizing plate.

[0014] Furthermore, it also includes a plurality of slurry-blocking inclined plates, which are connected in sequence and arranged in a surrounding shape on the homogenizing plate, and the plurality of through holes are all located on the inner side of the slurry-blocking inclined plates, and the tops of the plurality of slurry-blocking inclined plates are inclined away from the homogenizing plate.

[0015] Furthermore, it also includes a mounting plate, the pouring pipe is fixedly mounted on the mounting plate, and the mounting plate is installed between the two vertical poles through a moving mechanism.

[0016] Furthermore, the moving mechanism is a rodless cylinder, which is laterally arranged between the two vertical poles. The cylinder slider of the rodless cylinder is fixedly connected to the mounting plate. When performing the pouring operation, the rodless cylinder is controlled so that the cylinder slider of the rodless cylinder drives the mounting plate to move back and forth above the forming groove, thereby achieving the purpose of movably setting the pouring pipe between the two vertical poles. The reciprocating movement of the pouring pipe is also beneficial to improving the pouring and diffusion efficiency of the slurry.

[0017] In addition, for the motion scheme of driving the mounting plate to move above the forming groove, in addition to the rodless cylinder scheme, a screw drive scheme can also be adopted, that is, the moving mechanism includes a driving motor, a screw and a sliding rod, the screw is rotatably installed between the two vertical poles, the sliding rod is arranged between the two vertical poles, the driving motor is installed on the vertical pole, and the output shaft of the driving motor is connected to the screw, the mounting plate is threadedly connected to the screw, and the mounting plate is slidably connected to the sliding rod.

[0018] The beneficial effects of the present invention are as follows: by installing a slurry distribution pipe at the bottom of the pouring pipe and designing slurry outlet holes with radially distributed axial lines at the bottom of the slurry distribution pipe, the slurry can be sprayed onto the forming trough in a radial form when passing through these slurry outlet holes, thereby expanding the slurry pouring range to achieve the purpose of improving the diffusion efficiency of the slurry on the forming trough. The homogenizing plate located between the pouring pipe and the forming trough plays a role in secondary expansion of the pouring range and can further improve the diffusion efficiency. The reciprocating vibration of the vibrating cylinder on the homogenizing plate achieves the purpose of quickly diffusing the slurry on the homogenizing plate, thereby further improving the diffusion efficiency of the slurry.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] Example 1

[0030] See also Figures 1 to 6 , a material grading device for acrylic board production, comprising a forming tank 1 and a pouring pipe 2 mounted above the forming tank 1, see Figure 3 and Figure 4 , also includes a slurry distribution pipe 3, the top of the slurry distribution pipe 3 is installed at the bottom of the pouring pipe 2, the bottom of the slurry distribution pipe 3 is provided with a slurry distribution head 4, the inner cavity of the slurry distribution head 4 is connected to the inner cavity of the slurry distribution pipe 3, and the bottom wall of the slurry distribution head 4 is provided with a plurality of slurry outlet holes 5 connected to the inner cavity of the slurry distribution head 4. The central axis 51 of the plurality of slurry outlet holes 5 is radially distributed on the bottom wall of the slurry distribution head 4. When the slurry is poured, the slurry enters the slurry distribution pipe 3 at the bottom of the pouring pipe 2 through the feeding pipe. Since the bottom of the slurry distribution pipe 3 has a slurry distribution head 4 , and a plurality of slurry outlet holes 5 are provided on the bottom wall of the slurry distributing head 4. After the slurry passes through the inner cavity of the slurry distributing pipe 3, it leaves the slurry distributing pipe through the slurry outlet holes on the slurry distributing head. Since the central axis 51 of the slurry outlet holes 5 is radially distributed, the slurry will be radially ejected from the slurry distributing head 4 when passing through the slurry outlet holes 5. Compared with the traditional vertical falling method, the slurry ejected in a radial form plays a role in expanding the slurry pouring range, so as to achieve the purpose of improving the diffusion efficiency of the slurry on the forming trough 1.

[0031] Preferably, see Figure 3 、 Figure 4 and Figure 5The bottom wall of the distributing head 4 is in the shape of a spherical crown. Specifically, the spherical crown refers to the curved surface remaining after a sphere is cut by a plane. A plurality of distributing holes 5 are evenly distributed on the bottom wall of the distributing head 4. In this embodiment, the central axis 51 of the plurality of distributing holes 5 passes through the center of the distributing head 4 whose bottom wall is in the shape of a spherical crown. When pouring, since the distributing holes 5 are evenly distributed on the distributing head 4 in the shape of a spherical crown, the slurry will be sprayed out of the distributing head 4 in a radial form when passing through the distributing holes 5, just like a shower head, thereby achieving the purpose of expanding the pouring range.

[0032] Preferably, an internal thread is provided on the top inner wall of the slurry distribution pipe 5, and an external thread is provided on the outer wall of the pouring pipe 2. The slurry distribution pipe 5 is threadedly connected to the pouring pipe 2. The slurry distribution pipe 5 is detachably installed on the pouring pipe 2 in the form of tightening the threads, which can facilitate the disassembly and assembly of the slurry distribution pipe 5. When the slurry outlet is blocked, it is convenient to remove it for maintenance operations.

[0033] Preferably, see Figure 1 and Figure 6 , and also includes a homogenizing plate 6, which is arranged between the pouring pipe 2 and the forming tank 1. The homogenizing plate 6 is provided with a plurality of through holes 7, and the plurality of through holes 7 are distributed in a lattice shape on the homogenizing plate 6. The slurry passes through the slurry outlet holes 5 on the slurry distributor 4 and is sprayed onto the homogenizing plate 6. Since the homogenizing plate 6 has through holes 7 distributed in a lattice shape, part of the slurry sprayed from the slurry distributor 4 will directly pass through the through holes 7 and fall onto the forming tank 1, and then diffuse to other places in the forming tank 1 through natural flow, while the remaining slurry will first fall onto the homogenizing plate 6 and flow on the homogenizing plate 6. When the slurry on the homogenizing plate 6 passes through these through holes 7, it will fall directly from the through holes 7 to the forming tank 1. The blocking and diverting effect of the homogenizing plate 6 on the slurry plays a role in secondary expansion of the casting range, which can further improve the diffusion efficiency.

[0034] See also Figure 6The homogenizing plate 6 is provided with a plurality of protrusions 61. When the slurry is poured, when the slurry is sprayed onto the protrusions 61, part of the slurry will be blocked by the protrusions 61 and bounced up, and then fly to other positions of the homogenizing plate 6 or fly into the through hole 7 at a distance and directly fall onto the forming tank 1. Therefore, the protrusions 61 can enhance the slurry splashing effect and improve the slurry diffusion casting efficiency. The plurality of protrusions 61 are distributed in a lattice shape on the homogenizing plate 6. The protrusions 61 distributed in a lattice shape can enhance the overall diffusion of the slurry by the homogenizing plate 6. The dispersion efficiency is improved. Specifically, in the present embodiment, any one protrusion 61 is located between the four adjacent through holes 7. Specifically, the protrusion 61 is hemispherical. The hemispherical protrusion 61 has a smooth curved outer surface. When the slurry falls on the hemispherical protrusion 61, the curved outer surface of the protrusion 61 can slow down the impact and splash of the slurry, thereby avoiding excessive splashing of the slurry. The slurry that falls on the protrusion 61 without splashing will flow down along the outer surface of the protrusion 61 to the homogenizing plate 6, and to a certain extent, it also plays a role in guiding the slurry.

[0035] Preferably, see Figure 1 and Figure 2 , vertical rods 8 are provided on both sides of the forming trough 1, and the homogenizing plate 6 is movably installed between the two vertical rods 8. By movably arranging the homogenizing plate 6 between the two vertical rods 8, when performing the pouring operation, it is only necessary to provide the homogenizing plate 6 with a driving force for reciprocating movement, thereby achieving the purpose of vibrating the homogenizing plate 6 and improving the diffusion efficiency of the slurry on the homogenizing plate 6.

[0036] Preferably, a bottom frame 9 is provided between the two uprights 8, and a slide rail 10 is provided on the bottom frame 9, and the homogenizing plate 6 is slidably set on the bottom frame 9 through the slide rail 10, wherein the slide rail 10 is set along the length or width direction of the bottom frame 9. In this embodiment, the slide rail 10 is set along the length direction of the bottom frame 9, and the homogenizing plate 6 is slidably set on the bottom frame 9. It is only necessary to apply a reciprocating driving force to the homogenizing plate 6 in the sliding direction of the slide rail 10 so that the homogenizing plate 6 can reciprocate on the slide rail 10, which can play the role of reciprocating vibration of the homogenizing plate 6 left and right. In this way, the slurry falling onto the homogenizing plate 6 will undoubtedly be quickly vibrated on the homogenizing plate 6. In order to achieve the purpose of rapid diffusion flow, when the slurry diffuses and flows rapidly on the homogenizing plate 6, when it passes through the through hole 7, the slurry will directly fall from the through hole 7 to the forming tank 1. Since the through holes 7 are distributed in a lattice shape on the homogenizing plate 6, the slurry can be finally poured into the forming tank 1 in the form of a plane lattice through the reciprocating vibration of the homogenizing plate 6 during the pouring process of the slurry. Compared with the vertical direct pouring method, the plane lattice pouring method undoubtedly greatly improves the diffusion efficiency of the slurry, reduces the time it takes for the slurry to fill the forming tank 1 by natural flow, and is conducive to the formation of an acrylic board with uniform thickness.

[0037] Preferably, a slider 11 is provided at the bottom of the homogenizing plate 6, and the slider 11 is slidably connected to the slide rail 10 to achieve the purpose of sliding the homogenizing plate 6 on the bottom frame 9. A vibration cylinder 12 is provided on the bottom frame 9, and the piston rod of the vibration cylinder 12 is connected to the homogenizing plate 6. When the pouring operation is performed, the piston rod of the vibration cylinder 12 is driven to perform reciprocating motion, thereby achieving the purpose of driving the homogenizing plate 6 to perform left and right reciprocating vibration motion.

[0038] As a preferred solution of this embodiment, see Figure 2 , and also includes a number of slurry-blocking inclined plates 13, which are connected in sequence and arranged in an enclosed shape on the homogenizing plate 6, and a number of through holes 7 are all located on the inner side of the slurry-blocking inclined plates 13, that is, a number of slurry-blocking inclined plates 13 are surrounded and arranged on the outside of all through holes 7, wherein the number of slurry-blocking inclined plates 13 is three, and the two side ends of all slurry-blocking inclined plates 13 are connected in sequence, which can effectively prevent the slurry falling on the homogenizing plate 6 from splashing out of the homogenizing plate 6, and the tops of the several slurry-blocking inclined plates 13 are inclined away from the homogenizing plate 6, which is conducive to providing movement space for the casting pipe 2.

[0039] See also Figure 1 and Figure 2 In this embodiment, a mounting plate 14 is also included, and the pouring pipe 2 is fixedly mounted on the mounting plate 14. The mounting plate 14 is installed between the two vertical poles 8 through a moving mechanism. Through the moving mechanism, the pouring pipe 2 can be moved above the molding trough 1, which is beneficial to improving the pouring and diffusion efficiency of the slurry.

[0040] Preferably, the moving mechanism is a rodless cylinder 15, which is laterally arranged between the two vertical poles 8. The cylinder slider 16 of the rodless cylinder 15 is fixedly connected to the mounting plate 14. When performing the pouring operation, the rodless cylinder 15 is controlled so that the cylinder slider 16 of the rodless cylinder 15 drives the mounting plate 14 to move back and forth above the forming groove 1, thereby achieving the purpose of movably setting the pouring pipe 2 between the two vertical poles 8. The reciprocating movement of the pouring pipe 2 is also beneficial to improving the pouring and diffusion efficiency of the slurry.

[0041] Working principle: When performing the pouring operation, the rodless cylinder 15 is started to drive the pouring pipe 2 to move back and forth on the forming trough 1 along the width direction of the forming trough 1. At the same time, the slurry is ejected radially through the slurry outlet holes 5 on the bottom wall of the slurry distributor 4 and falls onto the homogenizing plate 6. Part of the slurry will directly fall onto the forming trough 1 through the through hole 7 below the slurry distributor 4, and the remaining slurry will first fall onto the homogenizing plate 6, and then diffuse and flow on the homogenizing plate 6. By driving the vibration cylinder 12 to vibrate the homogenizing plate 6 back and forth, the slurry can be rapidly diffused on the homogenizing plate 6. During the diffusion flow, when passing through the through hole 7, the slurry will fall directly from the through hole 7 to the forming trough 1. Since the through holes 7 are distributed in the form of a planar lattice on the homogenizing plate 6, the slurry is finally poured into the forming trough 1 in the form of a planar lattice, which improves the diffusion efficiency of the slurry to achieve the purpose of forming an acrylic board with uniform thickness.

[0042] The beneficial effects of this embodiment are as follows: by installing a slurry distribution pipe at the bottom of the pouring pipe and designing slurry outlet holes with radially distributed axial lines at the bottom of the slurry distribution pipe, the slurry can be sprayed onto the forming trough in a radial form when passing through these slurry outlet holes, thereby expanding the slurry pouring range to achieve the purpose of improving the diffusion efficiency of the slurry on the forming trough. The homogenizing plate located between the pouring pipe and the forming trough plays a role in secondary expansion of the pouring range and can further improve the diffusion efficiency. The reciprocating vibration of the vibrating cylinder on the homogenizing plate achieves the purpose of quickly diffusing the slurry on the homogenizing plate, thereby further improving the diffusion efficiency of the slurry.

[0043] Example 2

[0044] In addition, see Figure 7 , for the motion scheme of driving the mounting plate to move above the forming trough 1, in addition to the rodless cylinder scheme, a screw drive scheme can also be adopted, that is, the moving mechanism includes a driving motor 17, a screw rod 18 and a slide rod 19, both ends of the screw rod 18 are rotatably mounted between the two vertical rods 8 through bearing seats (not shown in the accompanying drawings), and the slide rod 19 is arranged between the two vertical rods 8. The driving motor 17 is installed on the vertical rod 8, and the output shaft of the driving motor 17 is connected to the screw rod 18 to drive the screw rod 18 to rotate. The mounting plate 14 is threadedly connected to the screw rod 18, and the mounting plate 14 is slidably connected to the slide rod 19, wherein the screw rod 18 and the slide rod 19 are arranged in parallel. When the pouring operation is performed, the driving motor 17 drives the screw rod 18 to rotate, thereby achieving the purpose of driving the pouring pipe to move above the forming trough 1.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
