Description

Technical Field

[0001] The invention relates to the technical field of acrylic plate production, in particular to an edge trimming device for acrylic production. Background Art

[0002] Acrylic, also known as specially treated plexiglass, is a replacement product for plexiglass. Light boxes made of acrylic have the characteristics of good light transmittance, pure color, rich colors, beautiful and smooth appearance, taking into account both day and night effects, long service life, and no impact on use.

[0003] In the patent application with application announcement number CN213259814U, it includes a cutting plate and a supporting plate, a cutting handle is fixedly connected to the middle position of the top of the cutting plate, and both sides of the bottom of the cutting plate are fixedly connected to limit plates, and the limit plates are slidably connected to the supporting plate, threaded holes are opened on the front and back of the supporting plate, and the threaded holes are evenly distributed, the cutting plate is fixedly connected to the supporting plate by fastening bolts, and the bottom movable shaft of the supporting plate is connected to a sliding wheel. The utility model realizes the cutting of burrs and burrs on both sides of the acrylic plate at one time through the symmetrical setting of the fixed plate and the cutting blade, thereby improving the cutting efficiency. Through the setting of the sliding wheel, the advantages are: the cutting device of the utility model is easy to move, the cutting resistance is reduced, the cutting labor is reduced, and the cutting efficiency is indirectly improved.

[0004] In the prior art including the above-mentioned patent, the above-mentioned scheme proposes to cut the edge burrs and burrs of the circular acrylic plate by a cutting blade. During the cutting process, if the tool speed is too high or the feed speed is too fast, the cutting force will be too large, thereby causing cracks or fractures at the edge of the acrylic plate. Similarly, excessive cutting depth will also cause the plate to be unable to withstand the excessive cutting force and fracture. At the same time, a large amount of debris will be generated during the cutting process. After high-frequency friction, the surface of the acrylic plate is very likely to carry a large amount of static electricity, thereby absorbing a large amount of debris. The existing common method of removing debris is manual removal or removal by blowing with an air pump and an air blow gun, which is difficult to remove directly after cutting, resulting in a decrease in the production efficiency of the acrylic plate.

A fan-shaped air outlet is provided at the output end of the nozzle 46.

[0050] When grinding the acrylic plate body 16, the driving motor 131 and the main motor 121 can be started, and the driving motor 131 can drive the cutter head 13 to rotate under the connection of the rotating shaft, and the main motor 121 can drive the cutter head 13 to revolve around the central axis of the acrylic plate body 16 under the connection of the rotating shaft, so as to grind the edge of the acrylic plate body 16. The above belongs to the prior art and will not be elaborated here.

[0051] During the trimming process of the acrylic plate body 16, the hydraulic rod 18 is started to drive the pressing pad 15 to descend, and the two ends of the acrylic plate body 16 are pushed to be tightly attached to the receiving pad 14 and the pressing pad 15. At the same time, the descent of the pressing pad 15 can drive the support arm 21 and the arc-shaped baffle plate 22 to descend at the same time, so that the two sets of pressing wheels 24 are tightly attached to the edges of the two ends of the acrylic plate body 16 respectively. Under the downward pressure of the pressing pad 15, the return spring 231 between the inner slide seat 23 and the arc-shaped baffle plate 22 can be compressed. Under the elastic force of the return spring 231, the material at the cutting position of the acrylic plate body 16 is in a relatively stable state, which can prevent the acrylic plate body 16 from cracking during the cutting process. During the descending process of the pressing pad 15, the latch seat fixedly connected to the support arm 21 located above the acrylic plate body 16 can be sleeved on the outside of the latch rod. At this time, by starting the driving motor 131 and the main motor 121, the cutter head 13 rotates and makes a circular motion around the center of the acrylic plate body 16. At the same time, the support arm 21 can rotate around the connection position with the pressing pad 15. Since the bevel gear ring 31 is fixed to the side of the pressing pad 15, and the bevel gear 32 rotates inside the pressing pad 15, the bevel gear 32 can be rotated by the meshing action of the bevel gear ring 31 and the bevel gear 32, and the transmission rod 33 fixed to the end of the bevel gear 32 can be driven to rotate. At this time, the guide block fixed to the inner wall of the sleeve seat 34 341 can enter the first guide groove 351 from the connection between the first guide groove 351 and the second guide groove 352. At this time, the piston body 421 can slide toward the third one-way valve 432 under the connection of the piston rod 42. At this time, the air pressure inside the piston cylinder 43 on the side of the piston body 421 close to the second one-way valve 431 is reduced, the second one-way valve 431 is opened, and the first one-way valve 422 is in a closed state. The air outside the piston cylinder 43 enters the piston cylinder 43 through the second one-way valve 431. At the same time, the air pressure inside the piston cylinder 43 on the side of the piston body 421 close to the third one-way valve 432 is increased, so that the third one-way valve 432 is opened, so that the piston cylinder 43 close to the third one-way valve 432 is closed. The air on the side enters into the nozzle 46 through the air guide pipe 44 and is discharged through the nozzle 46, so as to remove the debris adhered to the acrylic plate body 16. When the guide block 341 fixed to the inner wall of the sleeve 34 can enter into the second guide groove 352 through the first guide groove 351, the piston body 421 slides toward the second one-way valve 431 at this time, and the air pressure inside the piston cylinder 43 on the side of the piston body 421 close to the second one-way valve 431 increases, the second one-way valve 431 is closed, and the first one-way valve 422 is in an open state, and the air inside the piston cylinder 43 close to the second one-way valve 431 side enters into the other side of the piston cylinder 43 through the first one-way valve 422, and the third one-way valve 432 is closed at the same time.

[0052] A flame spraying and polishing assembly 5 is arranged above the support arm 21 located above the acrylic plate body 16. The flame spraying and polishing assembly 5 includes an upper extension rod 51 fixed to the end of the sleeve 36. Two pushing and rotating rods 52 are rotatably arranged at the top of the upper extension rod 51. A flame spraying seat 53 is rotatably arranged at the other end of each pushing and rotating rod 52. Each flame spraying seat 53 is slidably connected to the arc baffle 22. A flame spraying head 54 is installed on each flame spraying seat 53. An arc groove matching the flame spraying seat 53 is opened on the arc baffle 22.

[0053] The spray head 46 is located above the arc-shaped edge of the acrylic plate body 16 , the output ends of the two flame spray heads 54 are both located above the arc-shaped edge of the acrylic plate body 16 , and the cutter head 13 is in close contact with the arc-shaped outer wall of the acrylic plate body 16 .

[0054] During the trimming process of the acrylic plate body 16, the hydraulic rod 18, the drive motor 131 and the main motor 121 are started, so that the receiving pad 14 and the pressing pad 15 are both in close contact with the outer wall of the acrylic plate body 16, and the cutter head 13 can rotate and revolve at the same time to grind the acrylic plate body 16. In this process, with the cooperation of the transmission component 3, the sleeve 36 can be reciprocated on the inner wall of the support arm 21, driving the upper extension rod 51 to slide reciprocatingly, and then driving the pushing rotating rod 52 rotatably connected to the upper extension rod 51 to rotate around the connection position with the flamethrower seat 53, and at the same time driving the flamethrower head 54 to slide reciprocatingly on the arc baffle 22. At this time, the flamethrower head 54 is started to soften and deburr the cleaned acrylic plate body 16 to make its surface smoother.

[0055] The working principle and use process of the present invention are as follows: by starting the hydraulic rod 18, the pressing pad 15 is driven to descend, and the two ends of the acrylic plate body 16 are pushed to be in close contact with the receiving pad 14 and the pressing pad 15 respectively. At the same time, the descent of the pressing pad 15 can drive the support arm 21 and the arc-shaped baffle plate 22 to descend at the same time, so that the two sets of pressing wheels 24 are in close contact with the edges of the two ends of the acrylic plate body 16 respectively. Under the downward pressure of the pressing pad 15, the return spring 231 between the inner slide seat 23 and the arc-shaped baffle plate 22 can be compressed. Under the elastic force of the return spring 231, the material at the cutting position of the acrylic plate body 16 is in a relatively stable state, which can prevent the acrylic plate body 16 from being damaged during the cutting process. In the process of the pressing pad 15 descending, the pin seat fixedly connected to the support arm 21 above the acrylic plate body 16 can be sleeved on the outside of the pin rod. At this time, by starting the driving motor 131 and the main motor 121, the cutter head 13 can rotate and revolve at the same time, and the edge of the acrylic plate body 16 can be polished. At the same time, with the cooperation of the impurity removal component 4, the jet head 46 can be used to blow air to the edge of the acrylic plate body 16 to remove debris. At the same time, with the cooperation of the flame polishing component 5, the flame head 54 can be started at the same time, and the cleaned acrylic plate body 16 can be softened and deburred reciprocatingly to make its surface smoother.
