Description

Technical Field

[0001] The present invention relates to the field of acrylic sheet manufacturing, and particularly to a production device for acrylic sheets with simulated textures. Background Art

[0002] Acrylic sheets, commonly known as specially treated plexiglass sheets, have the advantages of being lightweight, inexpensive, and easy to form, and are widely used in the existing market. In order to make the produced acrylic sheets have an aesthetic appearance, manufacturers basically mix other color slurries, i.e., auxiliary color slurries, into the main color slurry during the casting production process of acrylic sheets. Since the color of the auxiliary color slurry is different from that of the main color slurry, the purpose of drawing texture patterns on the acrylic sheets is achieved, such as wood-grain imitation acrylic sheets or marble imitation acrylic sheets, etc.

[0003] In the casting production of existing simulated texture acrylic sheets, the drawing of simulated texture lines is usually achieved by the movement of an auxiliary color casting gun above a forming groove. In the specific casting method, first, the main color slurry is injected into the forming groove, and then the movement of the auxiliary color casting gun above the forming groove is controlled by a walking mechanism. The auxiliary color casting gun performs the casting and drawing operation of the auxiliary color slurry while moving above the main color slurry, thereby completing the drawing operation of the marble imitation texture.

[0004] Although this kind of casting and drawing operation of simulated texture can draw textures in the main color slurry, this kind of texture drawing operation can only achieve the surface drawing effect and cannot achieve the three-dimensional drawing effect along the thickness direction of the main color slurry, resulting in a poor three-dimensional simulation effect of the produced marble imitation acrylic sheets. Moreover, during the casting production process of acrylic sheets, after the main color slurry is poured into the forming groove, the uniform spreading of the main color slurry on the forming groove is generally achieved by its own diffusion and flow. However, due to the relatively fast coagulation and curing speed of the main color slurry itself, the produced acrylic sheets often have the problem of uneven thickness, affecting the product quality. Summary of the Invention

Detailed Embodiment

[0035] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] See Figures 1 to 12 , a production device for acrylic plates with simulated textures, including a frame 1, a main color pouring gun 2, and a conveying roller group 4 for driving the forming groove 3 to move forward. See Figures 1 to 3 , the conveying roller group 4 is installed on the frame 1 and is driven to operate by a motor (not shown in the drawings). In this embodiment, a thin steel belt 31 is tensioned on the conveying roller group 4, and rubber strips 32 are provided on both sides of the thin steel belt 31 in the length direction. The rubber strips 32 are combined with the thin steel belt 31 to form the forming groove 3. The main color pouring gun 2 is arranged above the forming groove 3. Specifically, it further includes a three-dimensional drawing mechanism 5, a slurry equalizing device 6, and a heating device 7 for heating and solidifying the acrylic slurry on the forming groove 3. The slurry equalizing device 6 is located between the main color pouring gun 2 and the forming groove 3. The three-dimensional drawing mechanism 5 is located above the forming groove 3 and on one side of the slurry equalizing device 6 along the conveying direction of the conveying roller group 4. The heating device 7 is located on one side of the three-dimensional drawing mechanism 5 along the conveying direction of the conveying roller group 4. That is, in the conveying direction of the conveying roller group 4, the slurry equalizing device 6, the three-dimensional drawing mechanism 5, and the heating device 7 are arranged in sequence;

[0037] See Figures 7 to 12, the three-dimensional drawing mechanism 5 includes a bottom frame 51 and an intermediate frame 52. The intermediate frame 52 is disposed above the bottom frame 51 in a vertically liftable manner. A plurality of first secondary color pouring guns 8 are fixedly provided on the bottom frame 51, and a plurality of second secondary color pouring guns 9 are fixedly provided on the intermediate frame 52. The nozzles at the bottoms of the second secondary color pouring guns 9 pass through the bottom frame 51, and the nozzles at the tops of the first secondary color pouring guns 8 pass through the intermediate frame 52. The nozzles of the first secondary color pouring guns 8 and the nozzles of the second secondary color pouring guns 9 can both be inserted into the main color slurry 21 in the molding groove 3. Specifically, in this embodiment, the bottom frame 51 and the intermediate frame 52 are spaced apart in a stacked form in the vertical direction, that is, the intermediate frame 52 is disposed directly above the bottom frame 51, so that the first secondary color pouring gun 8 can pass through the intermediate frame 52 normally during the lifting movement of the intermediate frame 52. Similarly, the second secondary color pouring gun 9 can also pass through the bottom frame 51 without interference. The first secondary color pouring gun 8 and the second secondary color pouring gun 9 are both connected to the conveying pipes of the secondary color slurry. See Figure 9 , during use, both the first secondary color pouring gun 8 and the second secondary color pouring gun 9 on the bottom frame 51 are inserted into the main color slurry 21 in the molding groove 3. Since the intermediate frame 52 is disposed above the bottom frame 51 in a vertically liftable manner and the second secondary color pouring gun 9 is fixedly provided on the intermediate frame 52, by controlling the distance between the intermediate frame 52 and the bottom frame 51, the vertical distance between the nozzle at the bottom of the second secondary color pouring gun 9 and the nozzle of the first secondary color pouring gun 8 can be adjusted. Thus, both the second secondary color pouring gun 9 and the first secondary color pouring gun 8 can inject the secondary color slurry at different positions in the thickness direction within the main color slurry 21, so as to achieve the purpose of pouring the secondary color slurry at different depths inside the main color slurry 21. Furthermore, the produced acrylic board has a three-dimensional simulation texture, enhancing the three-dimensional simulation effect of the product. And during the pouring process, by introducing different colored secondary color slurries into the first secondary color pouring gun 8 and the second secondary color pouring gun 9 respectively, a simulated texture acrylic board with multiple color textures can be produced, enhancing the diversity of the texture colors of the product;

[0038] See Figures 4 to 6, the homogenizing device 6 includes a homogenizing frame 61 and a plurality of longitudinal slurry retaining grooves 62. The homogenizing frame 61 is arranged between the main color pouring gun 2 and the molding groove 3. A vibration mechanism is provided between the homogenizing frame 61 and the machine frame 1. The plurality of longitudinal slurry retaining grooves 62 are arranged at intervals along the length direction of the homogenizing frame 61 on the inner side of the homogenizing frame 61. A plurality of first through holes 63 are arranged at intervals on the bottom of the longitudinal slurry retaining grooves 62. When performing the pouring operation of the main color slurry 21, the main color slurry 21 comes out from the slurry outlet at the bottom of the main color pouring gun 2 and will directly fall. During the falling process of the main color slurry 21, the main color slurry 21 above the gap between any two adjacent longitudinal slurry retaining grooves 62 will directly pass through the gap between the longitudinal slurry retaining grooves 62 and fall onto the molding groove 3, and then spread to other places of the molding groove through natural flow. The main color slurry 21 directly above the longitudinal slurry retaining groove 62 will directly fall onto the longitudinal slurry retaining groove 62. The freely falling main color slurry 21 will spread and flow into the longitudinal slurry retaining groove 62 under the blocking and impact action of the longitudinal slurry retaining groove 62. Also, since a plurality of first through holes 63 are arranged at intervals in the longitudinal slurry retaining groove 62, when the main color slurry 21 in the longitudinal slurry retaining groove 62 passes through these first through holes 63, it will directly fall onto the molding groove 3 from the first through holes 63. In this way, the spaced first through holes 63 can play a role in expanding the pouring range of the slurry. Also, since the longitudinal slurry retaining grooves 62 are arranged at intervals along the length direction of the homogenizing frame 61, the purpose of spreading and pouring the main color slurry 21 in the width direction of the homogenizing frame 61 is realized. That is, by designing the longitudinal slurry retaining grooves 62 spaced from each other on the homogenizing frame 61 and arranging the homogenizing frame 61 between the molding groove 3 and the main color pouring gun 2, during the descending process of the main color slurry 21, the first through holes 63 can achieve the purpose of improving the slurry diffusion efficiency, so as to ensure that the main color slurry 21 can quickly and evenly cover the entire molding groove 3 before coagulation, ensure the thickness uniformity of the acrylic plate, and improve the product quality;

[0039] The heating device 7 is arranged on the machine frame 1, and a heating component is arranged in the heating device 7. The heating component is located above the molding groove 3 and is used to heat and keep warm the acrylic slurry after the simulation texture is drawn, so as to improve the slurry coagulation and curing efficiency and product quality.

[0040] Preferably, referring to Figure 7 , Figure 8 , Figure 9 and Figure 12, it further includes a top frame 53 which is arranged above the middle frame 52 in a liftable manner. A number of third secondary-color pouring guns 10 are fixedly arranged on the top frame 53. The nozzles at the bottoms of the third secondary-color pouring guns 10 sequentially pass through the middle frame 52 and the bottom frame 51. The nozzles of the third secondary-color pouring guns 10 are inserted into the main-color slurry 21 on the molding groove 3 in a liftable manner. The slurry inlet pipes at the tops of the first secondary-color pouring guns 8 sequentially pass through the middle frame 52 and the top frame 53, and the slurry inlet pipes at the tops of the second secondary-color pouring guns 9 pass through the top frame 53. By driving and adjusting the vertical distance between the top frame 53 and the middle frame 52, the third secondary-color pouring guns 10 can also move up and down relative to the nozzles of the first secondary-color pouring guns 8 in the vertical direction, so as to achieve the purpose of injecting the secondary-color slurry at different depth positions of the main-color slurry 21. By controlling multiple secondary-color pouring guns to perform texture injection operations at different depth positions, while further improving the three-dimensional simulation effect, it also enables the production equipment to have the function of simultaneously drawing multiple three-dimensional textures.

[0041] Preferably, referring to Figure 7 and Figure 8 , a first mounting plate 54 is fixedly arranged on the middle frame 52, a first push plate 55 is fixedly arranged on the bottom frame 51, a first air cylinder 56 is arranged on the first mounting plate 54, and the piston rod of the first air cylinder 56 is connected to the first push plate 55. By driving the first air cylinder 56, the function of adjusting the vertical distance between the middle frame 52 and the bottom frame 51 can be achieved; a second mounting plate 57 is fixedly arranged on the top frame 53, a second push plate 58 is fixedly arranged on the bottom frame 51, a second air cylinder 59 is arranged on the second mounting plate 57, and the piston rod of the second air cylinder 59 is connected to the second push plate 58.

[0042] Preferably, referring to Figure 3 , a bracket 510 connected to the external manipulator 20 is arranged on the bottom frame 51 to facilitate adjusting the distance between the bottom frame 51 and the molding groove 3.

[0043] Preferably, referring to Figures 4 to 6, the homogenizing device 6 further includes a plurality of transverse slurry retaining grooves 64. The plurality of transverse slurry retaining grooves 64 are arranged at intervals along the width direction of the homogenizing frame 61 on the inner side of the homogenizing frame 61. A plurality of second through holes 65 are arranged at intervals on the bottom of the transverse slurry retaining grooves 64. During the pouring process of the main color slurry 21, the main color slurry 21 falling onto the transverse slurry retaining grooves 64 will diffuse and flow into the transverse slurry retaining grooves 64 under the blocking and impact action of the transverse slurry retaining grooves 64. Also, since a plurality of second through holes 65 are arranged at intervals on the inner bottom wall of the transverse slurry retaining grooves 64, when the main color slurry 21 in the transverse slurry retaining grooves 64 passes through these second through holes 65, the main color slurry 21 will fall from the second through holes 65 onto the forming groove 3. In this way, the second through holes 65 arranged at intervals can play a role in expanding the pouring range of the main color slurry 21. Also, since the transverse slurry retaining grooves 64 are arranged at intervals along the width direction of the homogenizing frame 61, the purpose that the main color slurry 21 can be diffusely poured along the length direction of the homogenizing frame 61 is realized, further improving the diffusion efficiency of the main color slurry 21. Combining with the diffusion pouring effect of the longitudinal slurry retaining grooves 62 along the width direction of the homogenizing frame 61, the purpose of diffusely pouring the main color slurry 21 simultaneously along the width and length directions of the homogenizing frame, that is, the diffusion pouring of the planar lattice, is realized, fully ensuring the thickness uniformity of the acrylic plate.

[0044] Preferably, the longitudinal slurry retaining grooves 62 and the transverse slurry retaining grooves 64 intersect with each other on the homogenizing frame 61, and the longitudinal slurry retaining grooves 62 communicate with the transverse slurry retaining grooves 64; a protrusion 66 is provided at the top of the groove wall where the longitudinal slurry retaining grooves 62 and the transverse slurry retaining grooves 64 meet. During the pouring operation of the main color slurry 21, when the main color slurry 21 falls onto the protrusion 66, part of the main color slurry 21 will bounce due to the blocking and impact action of the protrusion 66 and then fly to other positions in the forming groove, playing a role in improving the diffusion efficiency of the main color slurry 21.

[0045] Preferably, referring to Figure 1 and Figure 4 , vertical rods 11 are provided on both sides of the frame 1. Specifically, the vertical rods 11 are arranged on both sides of the forming groove 3 along the width direction of the forming groove 3. A bottom plate 12 is provided between the two vertical rods 11. The middle of the bottom plate 12 is hollowed out to facilitate the falling of the main color slurry 21. A slide rail 13 is provided on the bottom plate 12. The slide rail 13 is arranged along the length direction of the bottom plate 12, that is, the width direction of the forming groove 3. The bottom of the homogenizing frame 61 is slidably connected to the slide rail 13 through a slider. A vibration mechanism is arranged between the homogenizing frame 61 and the bottom plate 12. The vibration mechanism is used to vibrate the homogenizing frame 61 so that the main color slurry 21 falling into the longitudinal slurry retaining grooves 62 and the transverse slurry retaining grooves 64 can diffuse quickly, further improving the diffusion efficiency of the main color slurry 21.

[0046] Preferably, referring to Figure 3 and Figure 4, the vibration mechanism includes a servo motor 14, a spring 15 and an eccentric wheel 16. The servo motor 14 is fixedly installed on the bottom plate 12. The output shaft of the servo motor 14 is connected to the eccentric wheel 16. One side of the slurry homogenization frame 61 is connected to the bottom plate 12 through the spring 15. Specifically, a stop block 17 is provided on the bottom plate 12, and the stop block 17 is arranged at the side end position of the bottom plate 12 close to the vertical rod 11. One end of the spring 15 is fixedly connected to the stop block 17, and the other end of the spring 15 is fixedly connected to the slurry homogenization frame 61, so that the slurry homogenization frame 61 has an elastic reset function relative to the stop block 17. Further, the other side of the slurry homogenization frame 61 abuts against the eccentric wheel 16. Driven by the servo motor 14, the eccentric wheel 16 can push the slurry homogenization frame 61 to move reciprocally, so as to achieve the purpose of vibrating the slurry homogenization frame 61. Under the rapid vibration of the eccentric wheel 16, the slurry homogenization frame 61 can rapidly diffuse the main color slurry 21 therein, thereby improving the diffusion efficiency of the main color slurry 21, and thus achieving the purpose that the main color slurry 21 can be fully diffused on the forming groove 3 before coagulation, improving the thickness uniformity of the acrylic plate, and achieving the purpose of improving the product quality.

[0047] Preferably, referring to Figure 4 , a rodless cylinder 18 is provided between the tops of the two vertical rods 11. The main color pouring gun is installed on the cylinder slider 19 of the rodless cylinder 18. By installing the main color pouring gun on the cylinder slider 19 and driving the movement of the rodless cylinder 18, the purpose of driving the main color pouring gun to move above the forming groove can be achieved, which is beneficial to the diffusion pouring operation of the main color slurry 21.

[0048] Preferably, the heating device 7 includes a housing 71. The housing 71 is wrapped around the outside of the forming groove 3. The heating component is arranged in the inner cavity of the housing 71, that is, the forming groove passes through the inside of the housing 71. Setting the housing 71 is beneficial to preventing heat dissipation and playing a heat preservation role. The heating component is an electric heating wire 72 arranged in an S shape above the forming groove. Through the heating of the electric heating wire 72, the purpose of uniform heating is achieved to improve the coagulation and curing efficiency of the slurry and the product quality.

[0049] Working principle: First, connect the conveying pipe of the main color slurry 21 to the main color pouring gun 2, and connect the conveying pipes of the auxiliary color slurries to the first auxiliary color pouring gun 8, the second auxiliary color pouring gun 9, and the third auxiliary color pouring gun 10. Then start the equipment to perform the pouring operation of the acrylic board. The main color slurry 21 falls onto the forming groove 3 through the main color pouring gun 2. During the falling process of the main color slurry 21, under the plane dot matrix pouring action of the homogenizing device 6 and the rapid vibration of the vibration mechanism on the homogenizing device 6, the main color slurry 21 can be quickly diffused onto the forming groove 3 below the main color pouring gun 2. Then, the forming groove 3 moves forward driven by the conveying roller group 4, so that the forming groove 3 can be continuously filled with the main color slurry 21 along the conveying direction of its conveying roller group 4. When the forming groove 3 filled with the main color slurry 21 runs below the three-dimensional drawing mechanism 5, refer to Figure 1 , Figure 2 and Figure 9 , by controlling the operation of the first cylinder 56 and the second cylinder 59, to control the first auxiliary color pouring gun 8, the second auxiliary color pouring gun 9, and the third auxiliary color pouring gun 10 to insert into different depth positions of the main color slurry 21. Then, the auxiliary color slurry is injected into the main color slurry 21 through the auxiliary color pouring gun. Combining with the forward movement of the forming groove 3, the purpose of drawing three-dimensional textures in the main color slurry 21 is realized. Then, after drawing the three-dimensional textures, the acrylic board slurry in the forming groove 3 enters the heating device 7 under the conveying action of the conveying roller group 4 for heating and heat preservation, so that it solidifies and condenses into an acrylic board. Finally, it comes out from the outlet of the heating device 7 and is cut into acrylic products with simulation textures of corresponding models by the subsequent plate cutting mechanism.

[0050] Beneficial effects of this embodiment: Through the insertion and pouring operation of the three-dimensional drawing mechanism, the purpose of pouring the auxiliary color slurry at different internal depth positions in the main color slurry 21 is realized, so that the produced acrylic board has three-dimensional simulation textures, improving the three-dimensional simulation effect of the product. During the pouring process of the main color slurry 21, through the plane dot matrix diffusion action of the homogenizing device and the reciprocating vibration of the vibration mechanism on the homogenizing device, the purpose of quickly and evenly covering the entire forming groove before the main color slurry 21 condenses is realized, ensuring the thickness uniformity of the acrylic board and improving the product quality.
