Description

Technical Field

[0001] The present invention belongs to the technical field of acrylic sheet processing, and specifically relates to a device for generating random patterns on acrylic sheets. Background Technique

[0002] Acrylic sheet, also known as specially treated plexiglass, is a sheet made of polymethyl methacrylate (PMMA), which has good transparency, chemical stability and weather resistance, is easy to dye, easy to process and has a beautiful appearance. In the current existing devices for the processing of random patterns on acrylic sheets, the most commonly used and effective methods include laser internal engraving and manual drawing or embossing using specific tools. Among them, a laser internal engraving machine can directly engrave random patterns inside the acrylic sheet, presenting a unique visual effect;

[0003] When acrylic sheets are processed with random patterns in the prior art, the acrylic sheets used are specifically rectangular acrylic groove plates. After the patterns are attached to the inner walls, a flat acrylic sheet is subsequently fixedly installed with it in a tight fit. However, among the above-mentioned production methods, except for the manual drawing method, the others are all carried out by means of mechanical programming. Therefore, although they seem to be "random", they are actually all products pre-planned by programming, and manual drawing is too inefficient. Summary of the Invention

[0008] Preferably, arc angle plates are fixedly connected to the outer walls of the bottom ends of the two telescopic rods, two tapered blocks are respectively fixedly connected to the outer walls of the bottom ends of the two arc angle plates, and the bottom ends of the two groups of tapered blocks can be intermittently and slidably connected to the inner walls of the top ends of each acrylic groove plate.

[0010] Preferably, the meshing transmission structure includes a meshing component arranged on the screw. The meshing component is specifically composed of two meshing spur gears. One spur gear is fixedly connected to the outer wall of the solid rod body of the screw, and a disc is rotatably connected to the outer wall of the top end of the other spur gear. A blanking hole is formed through the other spur gear and the disc.

[0011] Preferably, a support rod is movably sleeved in the inner wall of the bottom end of the other spur gear, the bottom end of the support rod is fixedly connected to the outer wall of the top end of the groove plate box, a lime material box is fixedly connected to the outer wall of the disc, a lime plug is fixedly connected through the inner wall of the top end of the lime material box, and a support plate is jointly fixedly connected between the outer walls of both ends of the lime material box and the outer walls of both sides of the top end of the U-shaped frame.

[0012] Preferably, a hopper pipe is fixedly connected through the rod body of the support rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] In the present invention, the motor is started to drive the screw to rotate. The rotating screw drives the pressure plate to rotate and move downward on its rod body. The downward-moving pressure plate squeezes the corrugated pipe, generating negative pressure inside it, so as to squeeze and discharge the pre-aspirated and diluted acrylic paint. When the acrylic paint is squeezed and discharged, it will move downward rapidly with impact force to the ball-axis nozzle. And when the ball-axis nozzle is suddenly impacted, it will shake with a certain fluctuation at the nozzle of the corrugated pipe. Since the fluctuations received by the ball-axis nozzle and the initial throwing force on the paint cannot ensure its specificity each time, the paint forming the pattern during feeding is a unique random pattern each time. When the pressure plate rotates and moves downward passively, it will also drive the sleeve rod and the telescopic rods, arc angle plates, and tapered blocks installed at both ends thereof to rotate and move downward synchronously until the two tapered blocks contact the inner wall of the acrylic groove plate. Thus, during the passive rotation process, the tapered blocks will rotate and stir the paint sprayed on the inner wall of the acrylic groove plate. The tapered blocks at specific positions and angles stir the paint with unspecified positions, making it form a random and richer pattern;

[0017] When the screw rotates in the present invention, it will also drive the meshing components to drive each other. Thus, when the spur gear with a feeding hole is rotated and aligned with the feeding hole on the upper disc, it can drive a small amount and intermittent feeding of quicklime in the quicklime tank. The fed quicklime will be introduced into the water tank through the hopper pipe and mixed with the water in it to heat up the water body. The heated water body will generate water vapor, and the water vapor will automatically rise and pass through the filter of the filter net on the air guide pipe, and directly float down from the other end nozzle of the air guide pipe into the air outlet groove plate. Thus, the bottom end of the air outlet groove plate will continuously emit hot gas, thereby drying and shaping the random pattern on the inner wall of the acrylic groove plate.

[0029] 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 making creative efforts belong to the protection scope of the present invention.

[0030] As Figures 1 to 8 shown, the present invention provides a device for generating random patterns on an acrylic plate, including a conveyor device 1, on which a plurality of acrylic tank boards 11 are adhesively connected, and a pattern making part 2 is further provided on the conveyor device 1. The pattern making part 2 includes a tank board box 21 fixedly connected to the top side wall of the conveyor device 1. A U-shaped frame 22 is fixedly connected to the top side wall of the tank board box 21. A motor 23 is fixedly connected to the outer wall of the top of the U-shaped frame 22. A screw rod 24 is fixedly connected to the rotating shaft of the motor 23. The rod body of the screw rod 24 is specifically also rotatably connected through the plate body of the U-shaped frame 22, and the inner wall of the lower half of the rod body of the screw rod 24 is specifically in a hollow state. A rotary pressing structure and a meshing transmission structure are provided on the rod body of the screw rod 24, thereby generating random patterns and quickly drying the pattern pigments.

[0031] Adopting the above - mentioned solution: By starting the motor 23, it drives the screw rod 24 to rotate. The rotating screw rod 24 will drive the pressure plate 25 to rotate and move downward on its rod body. Thus, the downward - moving pressure plate 25 will squeeze the corrugated pipe 26, generating negative pressure inside it, so as to squeeze and discharge the pre - aspirated and diluted acrylic paint. When the acrylic paint is squeezed and discharged, it will quickly move downward with impact force to the ball - shaft nozzle 29. And when the ball - shaft nozzle 29 is suddenly impacted, it will shake with a certain fluctuation at the nozzle of the corrugated pipe 26. Because the fluctuation received by the ball - shaft nozzle 29 and the initial throwing force on the paint cannot ensure its specificity each time, the paint formed into patterns by feeding is a unique random pattern each time. When the pressure plate 25 rotates and moves downward passively, it will also drive the sleeve rod 230 and the telescopic rods 231, arc - angle plates 232, and tapered blocks 233 installed at both ends of it to rotate and move downward synchronously until the two tapered blocks 233 contact the inner wall of the acrylic groove plate 11. Thus, during the passive rotation process of the tapered blocks 233, they will rotate and stir the paint sprayed on the inner wall of the acrylic groove plate 11. The tapered blocks 233 at specific positions and angles stir the paint with unspecified positions, making it form randomly shaped and more abundant patterns;

[0032] Meanwhile, when the screw rod 24 rotates, it will also drive the meshing components 237 to transmit to each other. Thus, when the straight gear with the feeding hole 239 rotates and aligns with the feeding hole 239 on the upper - side disc 238, it can drive a small amount and intermittently feed the quicklime in the quicklime tank 241. The fed quicklime will be introduced into the water tank 244 through the hopper pipe 243 and mixed with the water body inside it, heating the water body. The heated water body will generate water vapor, and the water vapor will automatically rise. After being filtered by the filter net 246 on the air duct 245, it will directly float down from the other end nozzle of the air duct 245 into the air - outlet groove plate 247. Thus, the bottom end of the air - outlet groove plate 247 will continuously emit hot gas, thereby drying and shaping the random patterns on the inner wall of the acrylic groove plate 11.

[0033] The rotation - and - downward - pressure structure includes a pressure plate 25 thread - connected to the screw rod 24. The inner bottom wall of the pressure plate 25 is movably sleeved with a corrugated pipe 26. A limiting - ring rod 27 is fixedly connected to the outer wall of the screw rod 24 near the bottom end. A limiting net plate 28 is fixedly connected to the bottom end of the limiting - ring rod 27. The limiting net plate 28 is rotationally clamped with the inner wall of the rigid plate body near the bottom of the corrugated pipe 26. A ball - shaft nozzle 29 is rotatably connected to the inner bottom wall of the corrugated pipe 26. A sleeve rod 230 is rotatably connected to the outer wall of the corrugated pipe 26. Telescopic rods 231 are fixedly connected through - hole at both side rods of the sleeve rod 230. The top side walls of the two telescopic rods 231 are respectively fixedly connected corresponding to the outer walls at both ends of the pressure plate 25.

[0034] Adopt the above scheme: Start the motor 23 to drive the screw rod 24 to rotate. The rotating screw rod 24 will drive the pressure plate 25 to rotate and move downward on its rod body. The downward-moving pressure plate 25 will squeeze the corrugated pipe 26 to generate negative pressure inside it, so as to squeeze and discharge the pre-sucked and diluted acrylic paint. When the acrylic paint is squeezed and discharged, it will move downward rapidly with impact force to the ball shaft nozzle 29. When the ball shaft nozzle 29 is suddenly impacted, it will shake with a certain fluctuation at the pipe orifice of the corrugated pipe 26, and then it will be driven by the continuously forced paint to discharge vertically and stably. Thus, the passively fluctuating ball shaft nozzle 29 will drive the paint to discharge in a fluctuating manner, so that the paint adhering to the inner wall of the acrylic groove plate 11 can form random patterns. Because the fluctuations received by the ball shaft nozzle 29 and the initial throwing force on the paint cannot ensure its specificity each time, the paint formed into patterns by discharging materials is a unique random pattern each time. When the screw rod 24 rotates, it will also synchronously drive the limit ring rod 27 and the limit mesh plate 28 to rotate in a limited way inside the corrugated pipe 26, in order to play a role in limiting the corrugated pipe 26.

[0035] Arc angle plates 232 are fixedly connected to the outer walls of the bottoms of the two telescopic rods 231. Two conical blocks 233 are respectively and fixedly connected to the outer walls of the bottoms of the two arc angle plates 232. The bottoms of the two groups of conical blocks 233 can be intermittently and slidably connected in a fitting manner with the inner walls of the tops of each acrylic groove plate 11. One end of the hollow rod body of the screw rod 24 is fixedly connected with a transfusion pipe 234 through penetration. The other end of the transfusion pipe 234 is fixedly connected with a paint box 235 containing diluted acrylic paint through penetration. A box plug is fixedly connected to the top of the paint box 235 through penetration. The outer wall of the bottom of the paint box 235 is fixedly connected with the outer wall of the top of the groove plate box 21. A one-way valve 236 is fixedly connected to the pipe body of the transfusion pipe 234.

[0036] Adopt the above scheme: When the corrugated pipe 26 is not squeezed subsequently, the passive upward movement process will suck the paint in the paint box 235 again through the transfusion pipe 234. When the pressure plate 25 rotates and moves downward passively, it will also drive the sleeve rod 230 and the telescopic rods 231, arc angle plates 232, and conical blocks 233 installed at both ends thereof to rotate and move downward synchronously until the two groups of conical blocks 233 contact the inner wall of the acrylic groove plate 11. And during the process of the pressure plate 25 being forced to move downward continuously, the telescopic rod 231 will retract a certain distance. Thus, the conical blocks 233 will rotate and stir the paint sprayed on the inner wall of the acrylic groove plate 11 during the passive rotation process. The conical blocks 233 at specific positions and angles stir the paint with unspecified positions, making it form randomly shaped and more abundant patterns.

[0037] The meshing transmission structure includes a meshing component 237 provided on the screw 24. The meshing component 237 is specifically composed of two meshing and connected spur gears. One spur gear is fixedly connected to the outer wall of the solid rod of the screw 24, and a disc 238 is rotatably connected to the outer wall of the top end of the other spur gear. A material discharge hole 239 is formed through both the other spur gear and the disc 238. A support rod 240 is movably sleeved in the inner wall of the bottom end of the other spur gear, and the bottom end of the support rod 240 is fixedly connected to the outer wall of the top end of the trough plate box 21. A lime material box 241 is also fixedly connected to the outer wall of the disc 238. A lime plug is fixedly connected through the inner wall of the top end of the lime material box 241. A support plate 242 is fixedly connected between the outer walls of both ends of the lime material box 241 and the outer walls of both sides of the top end of the U-shaped frame 22.

[0038] With the above scheme: When the screw 24 rotates, it will also drive the meshing component 237 to transmit each other. Thus, when the spur gear with the material discharge hole 239 rotates and aligns with the material discharge hole 239 on the upper disc 238, it can drive the quicklime in the lime material box 241 to be discharged in small amounts and intermittently.

[0039] A hopper pipe 243 is fixedly connected through the rod body of the support rod 240. The top end of the hopper pipe 243 is movably sleeved in the inner wall of the bottom end of the other spur gear. The pipe body of the hopper pipe 243 is fixedly connected through the top plate of the trough plate box 21. A water tank 244 is fixedly connected through the bottom pipe body of the hopper pipe 243. An air guide pipe 245 is fixedly connected through the side wall of one end of the water tank 244 near the top. A filter screen 246 is fixedly connected in the inner wall of one end of the air guide pipe 245. An air outlet trough plate 247 is fixedly connected through the other end pipe body of the air guide pipe 245. The outer wall of the top end of the water tank 244 is fixedly connected to the inner wall of the top end of the trough plate box 21.

[0040] With the above scheme: The quicklime to be discharged will be introduced into the water tank 244 through the hopper pipe 243. After being mixed with the water in it, the water temperature will rise and heat up. The heated water will generate water vapor, and the water vapor will automatically rise and pass through the filter screen 246 on the air guide pipe 245 and directly float out of the other end pipe orifice of the air guide pipe 245 into the air outlet trough plate 247. Thus, the bottom end of the air outlet trough plate 247 will continuously emit hot gas, thereby drying and shaping the random patterns on the inner wall of the acrylic trough plate 11. Subsequently, the lime material box 241 can also be filled with water by opening the lime plug on the lime material box 241, and the water will flow into the water tank 244 to supplement the water body.

[0041] Working principle and usage process of the present invention: By starting the conveyor device 1, the acrylic trough plate 11 is conveyed through the trough plate box 21. While the conveyor device 1 is operating, the motor 23 is started to drive the screw rod 24 to rotate. The rotating screw rod 24 will drive the pressing disc 25 to rotate and move downward on its rod body. Thus, the downward-moving pressing disc 25 will squeeze the corrugated pipe 26 to generate negative pressure inside it, so as to squeeze and discharge the pre-sucked and diluted acrylic paint. When the acrylic paint is squeezed and discharged, it will rapidly move downward with impact force to the ball shaft nozzle 29. And when the ball shaft nozzle 29 is suddenly impacted, it will shake with a certain fluctuation at the nozzle of the corrugated pipe 26, and then it will be driven by the continuously forced paint to discharge vertically and stably. Thus, the passively fluctuating ball shaft nozzle 29 will drive the paint to discharge in a fluctuating manner, so that the paint adhering to the inner wall of the acrylic trough plate 11 can form random patterns. Because the fluctuations received by the ball shaft nozzle 29 and the initial throwing force on the paint cannot ensure its specificity each time, the paint formed into patterns by discharging each time is a unique random pattern. When the screw rod 24 rotates, it will also synchronously drive the limiting ring rod 27 and the limiting net plate 28 to rotate in a limiting manner inside the corrugated pipe 26, in order to play a limiting role on the corrugated pipe 26. At the same time, when the pressing disc 25 rotates and moves downward passively, it will also drive the sleeve rod 230 and the telescopic rods 231, arc angle plates 232, and tapered blocks 233 installed at both ends of it to rotate and move downward synchronously until the two tapered blocks 233 contact the inner wall of the acrylic trough plate 11. And during the process of the pressing disc 25 being continuously forced to move downward, the telescopic rod 231 will retract a certain distance. Thus, the tapered blocks 233 will rotate and stir the paint sprayed on the inner wall of the acrylic trough plate 11 during the passive rotation process. The tapered blocks 233 at specific positions and angles stir the paint with unspecified positions, so as to form randomly shaped and more abundant patterns;

[0042] At the same time, when the screw rod 24 rotates, it will also drive the meshing component 237 to transmit each other. Thus, when the straight gear with the material discharging hole 239 rotates and aligns with the material discharging hole 239 on the upper disc 238, it can drive the quicklime in the quicklime tank 241 to be discharged in small amounts and intermittently. The discharged quicklime will be introduced into the water tank 244 through the hopper pipe 243 and mixed with the water body inside it to heat up the water body. The heated water body will generate water vapor, and the water vapor will automatically rise and pass through the filter screen 246 on the air guide pipe 245 and directly float out from the other end nozzle of the air guide pipe 245 into the air outlet trough plate 247. Thus, the air outlet trough plate 247 will continuously emit hot gas at the bottom, so as to dry and shape the random patterns on the inner wall of the acrylic trough plate 11. Subsequently, the quicklime tank 241 with the drained quicklime can also be filled with water by opening the lime plug on the quicklime tank 241, so that it flows into the water tank 244 to supplement the water body.
