Description

Technical Field

[0001] The present invention relates to the field of acrylic sheet manufacturing, and particularly to a material leveling mechanism for acrylic sheet production. Background Art

[0002] Acrylic casting sheets are generally formed by injecting slurry into a forming tank through a pouring pipe and then coagulating and curing. During the casting production, a feeding pipe transports the slurry into the pouring pipe. The pouring pipe moves above the forming tank through a traveling mechanism and simultaneously injects the slurry into the forming tank. The slurry falls into the forming tank after leaving the pouring pipe and diffuses and flows in the forming tank to cover the entire forming tank. After that, it is coagulated and cured to form an acrylic casting sheet.

[0003] Since the coagulation and curing speed of the slurry itself is relatively fast during the production of acrylic casting sheets, in order to ensure the uniform thickness of the produced acrylic casting sheets and guarantee the product quality, it is very necessary to design a material leveling mechanism that can improve the diffusion efficiency of the slurry on the forming tank, so as to achieve the purpose of uniformly covering the entire forming tank before the slurry coagulates. Summary of the Invention

[0004] In order to achieve the purpose of improving the diffusion efficiency of the slurry on the forming tank, the present invention proposes a material leveling mechanism for acrylic sheet production.

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

[0006] A material leveling mechanism for acrylic sheet production, including a forming groove and a pouring pipe erected above the forming groove, further including a material leveling rack. The material leveling rack is arranged between the pouring pipe and the forming groove. The material leveling rack includes an outer frame and several longitudinal slurry retaining grooves arranged at intervals along the length direction of the outer frame. The bottom of the longitudinal slurry retaining groove is provided with several first through holes arranged at intervals. When performing the pouring operation of the slurry, the slurry comes out from the slurry outlet at the bottom of the pouring pipe and will fall directly. During the falling process of the slurry, the slurry above the gap between any two adjacent longitudinal slurry retaining grooves will directly pass through the gap between the longitudinal slurry retaining grooves and fall onto the forming groove, and then spread to other parts of the forming groove through natural flow. While the slurry directly above the longitudinal slurry retaining groove will fall directly onto the longitudinal slurry retaining groove. The freely falling slurry will spread and flow into the longitudinal slurry retaining groove under the blocking and impact of the longitudinal slurry retaining groove. Also, since there are multiple first through holes arranged at intervals in the longitudinal slurry retaining groove, when the slurry in the longitudinal slurry retaining groove passes through these first through holes, it will directly fall from the first through holes onto the forming groove. In this way, the spaced first through holes can play a role in expanding the pouring range of the slurry. Also, since the longitudinal slurry retaining grooves are arranged at intervals along the length direction of the material leveling rack, the purpose of spreading and pouring the slurry along the width direction of the material leveling rack is achieved. That is, by designing the longitudinal slurry retaining grooves spaced from each other on the material leveling rack and arranging the material leveling rack between the forming groove and the pouring pipe, during the falling process of the slurry, the purpose of improving the diffusion efficiency of the slurry can be achieved through the first through holes, so as to ensure that the entire forming groove is evenly covered with the slurry before coagulation, guarantee the thickness uniformity of the acrylic sheet, and improve the product quality.

[0007] Furthermore, the material leveling rack further includes several transverse slurry retaining grooves arranged at intervals along the width direction of the outer frame. The bottom of the transverse slurry retaining groove is provided with several second through holes arranged at intervals. During the pouring process of the slurry, the slurry falling onto the transverse slurry retaining groove will spread and flow into the transverse slurry retaining groove under the blocking and impact of the transverse slurry retaining groove. Also, since there are multiple second through holes arranged at intervals on the inner bottom wall of the transverse slurry retaining groove, when the slurry in the transverse slurry retaining groove passes through these second through holes, the slurry will fall from the second through holes onto the forming groove. In this way, the spaced second through holes can play a role in expanding the pouring range of the slurry. Also, since the transverse slurry retaining grooves are arranged at intervals along the width direction of the material leveling rack, the purpose of spreading and pouring the slurry along the length direction of the material leveling rack is achieved, further improving the diffusion efficiency of the slurry. Combining with the spreading and pouring effect of the longitudinal slurry retaining grooves along the width direction of the material leveling rack, the material leveling rack can achieve the purpose of spreading and pouring the slurry simultaneously along the width and length directions of the material leveling rack, fully guaranteeing the thickness uniformity of the acrylic sheet.

[0008] Furthermore, the longitudinal slurry retaining grooves and the transverse slurry retaining grooves are arranged to intersect with each other on the outer frame. The longitudinal slurry retaining grooves communicate with the transverse slurry retaining grooves. The connection of the longitudinal and transverse slurry retaining grooves expands the flow range of the slurry on the material leveling frame. The vertically and horizontally intersecting flow channels enable the slurry to flow and distribute on the material leveling frame in a grid-like form. When passing through the first through holes and the second through holes, the slurry can fall onto the forming groove in a planar dot matrix form, further improving the diffusion efficiency of the slurry.

[0009] Furthermore, a slurry guiding protrusion is provided at the top of the groove wall where the longitudinal slurry retaining groove and the transverse slurry retaining groove intersect. During the pouring operation of the slurry, when the slurry falls onto the slurry guiding protrusion, part of the slurry will bounce due to the blocking and impact of the slurry guiding protrusion and then fly to other positions in the forming groove, which plays a role in improving the diffusion efficiency of the slurry.

[0010] Furthermore, the slurry guiding protrusion is hemispherical or conical. The hemispherical slurry guiding protrusion has a smooth arc-shaped outer surface. When the slurry falls onto the hemispherical slurry guiding protrusion, the arc-shaped outer surface can slow down the impact and splashing of the slurry. In contrast, the slurry is more likely to flow down along the outer surface of the slurry guiding protrusion and enter the longitudinal slurry retaining groove or the transverse slurry retaining groove, playing a role in guiding the slurry.

[0011] Furthermore, vertical rods are provided on both sides of the forming groove, and the material leveling frame is movably installed on the vertical rods.

[0012] Furthermore, a bottom frame is provided between the two vertical rods. A first slide rail is provided on the bottom frame, and the material leveling frame is slidably arranged on the bottom frame through the first slide rail.

[0013] Furthermore, an intermediate frame is provided between the material leveling frame and the bottom frame. A first slider is provided at the bottom of the intermediate frame, and the first slider is slidably connected to the first slide rail. The material leveling frame is arranged on the intermediate frame. A first air cylinder is provided on the bottom frame, and the piston rod of the first air cylinder is connected to the intermediate frame.

[0014] Furthermore, a second slide rail is provided on the intermediate frame. The second slide rail is arranged staggeredly with the first slide rail. A second slider is provided at the bottom of the material leveling frame, and the second slider is slidably connected to the second slide rail. A second air cylinder is provided on the intermediate frame, and the piston rod of the second air cylinder is connected to the material leveling frame.

[0015] Further, it further includes a driving motor, a lead screw, a sliding rod and a mounting plate. The pouring pipe is fixedly installed on the mounting plate. The lead screw is rotatably installed between the two vertical rods. The sliding rod is installed between the two vertical rods. The lead screw and the sliding rod are arranged in parallel. The mounting plate is slidably connected to the sliding rod and threadedly connected to the lead screw. The driving motor is installed on the vertical rod, and the output shaft of the driving motor is connected to the lead screw.

[0016] Advantages of the present invention: By designing a material leveling frame with longitudinal slurry blocking grooves and transverse slurry blocking grooves installed internally at intervals between the forming groove and the pouring pipe, when the slurry falls into the longitudinal slurry blocking grooves and the transverse slurry blocking grooves, the purpose of improving the slurry diffusion efficiency is achieved under the blocking impact and guiding action of the longitudinal slurry blocking grooves and the transverse slurry blocking grooves. The longitudinal slurry blocking grooves and the transverse slurry blocking grooves intersecting with each other can achieve the purpose of the slurry falling onto the forming groove in the form of a planar lattice, further improving the slurry diffusion efficiency. The material leveling frame that makes a reciprocating planar motion between the forming groove and the pouring pipe can play a role in quickly vibrating and diffusing the slurry in the longitudinal slurry blocking grooves and the transverse slurry blocking grooves, and further achieving the purpose of uniform diffusion of the slurry.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0025] See Figures 1 to 5 , a material leveling mechanism for acrylic sheet production, including a forming groove 1 and a pouring pipe 2 erected above the forming groove 1, and further including a material leveling rack 3. The material leveling rack 3 is arranged between the pouring pipe 2 and the forming groove 1. See Figure 4 , the material leveling rack 3 includes an outer frame 4 and a plurality of longitudinal slurry retaining grooves 5 arranged at intervals along the length direction of the outer frame 4. A plurality of first through holes 6 arranged at intervals are provided at the bottom of the longitudinal slurry retaining grooves 5. When performing the pouring operation of the slurry, the slurry will directly fall out from the slurry outlet at the bottom of the pouring pipe 2. During the falling process of the slurry, the slurry above the gap between any two adjacent longitudinal slurry retaining grooves 5 will directly pass through the gap between the longitudinal slurry retaining grooves 5 and fall onto the forming groove 1, and then spread to other places of the forming groove 1 through natural flow. The slurry directly above the longitudinal slurry retaining groove 5 will directly fall onto the longitudinal slurry retaining groove 5. The freely falling slurry will spread and flow into the longitudinal slurry retaining groove 5 under the blocking and impact action of the longitudinal slurry retaining groove 5. Also, since a plurality of first through holes 6 are arranged at intervals in the longitudinal slurry retaining groove 5, when the slurry in the longitudinal slurry retaining groove 5 passes through these first through holes 6, it will directly fall onto the forming groove 1 from the first through holes 6. In this way, the spaced first through holes 6 can play a role in expanding the pouring range of the slurry. Also, since the longitudinal slurry retaining grooves 6 are arranged at intervals along the length direction of the material leveling rack 3, the purpose of spreading and pouring the slurry in the width direction of the material leveling rack 3 is realized. That is, by designing the longitudinal slurry retaining grooves 5 spaced from each other on the material leveling rack 3 and arranging the material leveling rack 3 between the forming groove 1 and the pouring pipe 2, during the falling process of the slurry, the purpose of improving the slurry diffusion efficiency can be achieved in the first through holes 6, so as to ensure that the entire forming groove 1 is evenly covered with the slurry before coagulation, ensure the thickness uniformity of the acrylic sheet, and improve the product quality.

[0026] In addition, when the slurry falls onto the longitudinal slurry retaining groove 5, although part of the slurry will splash up under the impact of the longitudinal slurry retaining groove 5, when this part of the splashed slurry falls onto other positions of the forming groove 1, it also plays a role in expanding the pouring range of the slurry. In specific settings, by only controlling the vertical distance between the pouring pipe 2 and the material leveling frame 3, the problem of the slurry splashing out of the forming groove 1 can be effectively avoided.

[0027] Preferably, referring to Figure 4 and Figure 5 , the material leveling frame 3 further includes a plurality of transverse slurry retaining grooves 7 arranged at intervals along the width direction of the outer frame 4 on the outer frame 4. A plurality of second through holes 8 are arranged at intervals on the bottom of the transverse slurry retaining grooves 7. During the pouring process of the slurry, the slurry falling onto the transverse slurry retaining grooves 7 will diffuse and flow into the transverse slurry retaining grooves 7 under the blocking and impact of the transverse slurry retaining grooves 7. Also, since a plurality of second through holes 8 are arranged at intervals on the inner bottom wall of the transverse slurry retaining grooves 7, when the slurry in the transverse slurry retaining grooves 7 passes through these second through holes 8, the slurry will fall onto the forming groove 1 from the second through holes 8. In this way, the second through holes 8 arranged at intervals can play a role in expanding the pouring range of the slurry. Also, since the transverse slurry retaining grooves 8 are arranged at intervals along the width direction of the material leveling frame 3, the purpose of the slurry being able to diffuse and pour along the length direction of the material leveling frame is realized, further improving the diffusion efficiency of the slurry. Combining with the diffusion and pouring effect of the longitudinal slurry retaining groove 5 along the width direction of the material leveling frame 3, the material leveling frame 3 can realize the purpose of diffusing and pouring the slurry in both the width and length directions of the material leveling frame at the same time, fully ensuring the thickness uniformity of the acrylic plate.

[0028] Preferably, the longitudinal slurry retaining groove 5 and the transverse slurry retaining groove 7 intersect with each other on the outer frame 3. The longitudinal slurry retaining groove 5 communicates with the transverse slurry retaining groove 7. The connection between the longitudinal slurry retaining groove 5 and the transverse slurry retaining groove 7 expands the flow range of the slurry on the material leveling frame 3. The criss-cross flow channels enable the slurry to flow and distribute in a grid-like form on the material leveling frame 3. And when passing through the first through holes 6 and the second through holes 8, the purpose of the slurry falling onto the forming groove 1 in a planar dot matrix form can be realized, further improving the diffusion efficiency of the slurry.

[0029] Preferably, referring to Figure 4 and Figure 5 , a slurry guiding protrusion 9 is provided at the top of the groove wall where the longitudinal slurry retaining groove 5 and the transverse slurry retaining groove 7 meet. When performing the pouring operation of the slurry, when the slurry falls onto the slurry guiding protrusion 9, part of the slurry will bounce up under the blocking and impact of the slurry guiding protrusion 9 and then fly to other positions in the forming groove 1, playing a role in improving the diffusion efficiency of the slurry.

[0030] Preferably, the slurry guiding protrusion 9 is hemispherical or conical. Since the hemispherical slurry guiding protrusion 9 has a smooth arc-shaped outer surface, when the slurry falls onto the hemispherical slurry guiding protrusion 9, the arc-shaped outer surface can play a role in slowing down the impact and splashing of the slurry. In contrast, the slurry is more likely to flow down along the outer surface of the slurry guiding protrusion 9 and enter into the longitudinal slurry retaining groove 5 or the transverse slurry retaining groove 7, thus playing a role in guiding the slurry.

[0031] Preferably, vertical rods 10 are arranged on both sides of the forming groove 1, and the material leveling frame 3 is movably installed on the vertical rods 10. By movably installing the material leveling frame 3 on the vertical rods 10, when performing the pouring operation, only by providing a driving force for the reciprocating movement of the material leveling frame 3, the purpose of vibrating the material leveling frame 3 can be achieved, and the diffusion efficiency of the slurry on the material leveling frame 3 can be improved.

[0032] Specifically, refer to Figures 1 to 3 , a bottom frame 11 is arranged between the two vertical rods 10, and a first slide rail 12 is arranged on the bottom frame 11. Specifically, the specific first slide rail 12 is arranged along the length direction of the bottom frame 11, and the material leveling frame 3 is slidably arranged on the bottom frame 11 through the first slide rail 12. Only by applying a driving force for the reciprocating movement of the material leveling frame 3 in the sliding direction of the first slide rail 12, so that the material leveling frame 3 can perform a reciprocating movement on the first slide rail 12. In this way, the effect of reciprocatingly vibrating the material leveling frame 3 can be achieved, and the purpose of improving the diffusion speed of the slurry in the longitudinal slurry retaining groove 5 and the transverse slurry retaining groove 7 can be realized, and further improving the pouring diffusion efficiency of the material leveling mechanism.

[0033] Specifically, an intermediate frame 13 is arranged between the material leveling frame 3 and the bottom frame 11. A first slider 14 is arranged at the bottom of the intermediate frame 13, and the first slider 14 is slidably connected with the first slide rail 12. The material leveling frame 3 is arranged on the intermediate frame 14 to achieve the purpose of slidably arranging the material leveling frame 3 on the bottom frame 11. A first cylinder 15 is arranged on the bottom frame 11, and the piston rod of the first cylinder 15 is connected to the intermediate frame 13. Specifically, the piston rod of the first cylinder 15 is arranged parallel to the first slide rail 12. The first cylinder 15 drives the piston rod to perform a reciprocating movement, and the piston rod can drive the intermediate frame 13 to perform a reciprocating sliding movement on the bottom frame 11. Also, since the material leveling frame 3 is installed on the intermediate frame 13, in this way, by driving the first cylinder 15, the purpose of reciprocatingly vibrating the material leveling frame 3 can be achieved to improve the pouring diffusion efficiency of the material leveling mechanism.

[0034] Preferably, a second slide rail 16 is provided on the intermediate frame 13. The second slide rail 16 is arranged staggeredly with the first slide rail 12, that is, the second slide rail 16 is arranged along the width direction of the bottom frame 11. A second slider 17 is provided at the bottom of the material leveling rack 3. The second slider 17 is slidably connected to the second slide rail 16. Through the second slider 17 at the bottom of the material leveling rack 3, the purpose of slidably installing the material leveling rack 3 on the intermediate frame 13 is achieved. A second cylinder 18 is provided on the intermediate frame 13. The piston rod of the second cylinder 18 is connected to the material leveling rack 3. Specifically, the piston rod of the second cylinder 18 is arranged parallel to the second slide rail 16. Through the second cylinder 18, the purpose of driving the material leveling rack 3 to perform reciprocating sliding movement on the second slide rail 16 can be achieved, that is, the purpose of driving the material leveling rack 3 to perform reciprocating sliding movement along the width direction of the bottom frame 11. Combined with the staggered arrangement of the first slide rail 12 and the second slide rail 16, the purpose of enabling the material leveling rack 3 to perform planar movement relative to the bottom frame 11 is achieved. Through the driving effect of the first cylinder 15 on the reciprocating movement of the intermediate frame 13 along the length direction of the bottom frame 11 and the driving effect of the second cylinder 18 on the reciprocating movement of the material leveling rack 3 along the width direction of the bottom frame 11, the purpose of driving the material leveling rack 3 to perform planar reciprocating movement is achieved. Obviously, when performing the pouring operation of the slurry, the material leveling rack 3 performing planar reciprocating movement can undoubtedly play a role in quickly vibrating and spreading the slurry in the longitudinal slurry retaining groove 5 and the transverse slurry retaining groove 7, further achieving the purpose of uniform spreading of the slurry.

[0035] Preferably, it further includes a driving motor 19, a lead screw 20, a slide bar 21 and a mounting plate 22. The pouring pipe 2 is fixedly installed on the mounting plate 22. Both ends of the lead screw 20 are respectively rotatably installed on two vertical rods 10 through bearing seats (not shown in the drawings). The slide bar 21 is installed between the two vertical rods 10. The lead screw 20 and the slide bar 21 are arranged in parallel. The mounting plate 22 is slidably connected to the slide bar 21 and is threadedly connected to the lead screw 20. The driving motor 19 is installed on the vertical rod 10, and the output shaft of the driving motor 19 is connected to the lead screw 20. The driving motor 19 drives the lead screw 20 to rotate, and the lead screw 20 can drive the mounting plate 22 to slide on the slide bar 21. Since the pouring pipe 2 is installed on the mounting plate 22 and is located above the forming groove 1, when performing the pouring operation, through the driving effect of the driving motor 19, the purpose of driving the pouring pipe 2 to move above the forming groove 1 can be achieved, so as to play a role in uniformly pouring the slurry onto the forming groove 1.

[0036] Working principle: Before the slurry pouring operation, the discharge port of the feeding pipe is inserted into the pouring pipe 2. During the pouring operation, the feeding pipe conveys the slurry into the pouring pipe 2, and the slurry comes out from the bottom of the pouring pipe 2 and falls. At the same time, the driving motor 19 is started, and the driving motor 19 drives the pouring pipe 2 to move above the forming groove 1. Then, the first cylinder 15 and the second cylinder 18 are controlled to perform corresponding reciprocating movement actions to drive the material leveling frame 3 to perform a planar movement above the forming groove 1. When the vertically falling slurry passes through the material leveling frame 3, a part of the slurry directly falls onto the forming groove 1 through the gap between the longitudinal slurry retaining groove 5 and the transverse slurry retaining groove 7, and a part of the slurry directly falls onto the longitudinal slurry retaining groove 5 or the transverse slurry retaining groove 7 in the material leveling frame 3 and flows and diffuses on the material leveling frame 3 during the planar reciprocating movement. Finally, it leaves the material leveling frame 3 through the first through hole 6 and the second through hole 8 and falls to other positions of the forming groove 1, and covers the entire forming groove 1 after natural flow.

[0037] Advantages of this embodiment: By designing a material leveling frame with a longitudinal slurry retaining groove and a transverse slurry retaining groove installed at intervals inside between the forming groove and the pouring pipe, when the slurry falls onto the longitudinal slurry retaining groove and the transverse slurry retaining groove, the purpose of improving the slurry diffusion efficiency is achieved under the blocking impact and guiding action of the longitudinal slurry retaining groove and the transverse slurry retaining groove. The longitudinally intersecting longitudinal slurry retaining groove and the transverse slurry retaining groove can achieve the purpose of making the slurry fall onto the forming groove in the form of a planar dot matrix, further improving the slurry diffusion efficiency. The material leveling frame that performs a planar reciprocating movement between the forming groove and the pouring pipe can play a role in quickly vibrating and diffusing the slurry in the longitudinal slurry retaining groove and the transverse slurry retaining groove, and further achieve the purpose of uniform diffusion of the slurry.
