[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the utility model belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0030] See also Figure 1 The utility model provides an acrylic chamfering device, including a base 1 and a placement component 2 arranged on the base 1 for supporting an acrylic plate to be chamfered, and a movable cutting component 6 is arranged on the top of the placement component 2, and the cutting component 6 is used to chamfer the four sides of the acrylic plate.

[0031] When performing chamfering of an acrylic plate, an operator places the acrylic plate to be chamfered on the placement component 2 in advance, and the cutting component 6 moves along the peripheral side of the acrylic plate on the top of the acrylic plate to chamfer the peripheral side of the acrylic plate.

[0032] In some embodiments, see Figure 1 The base 1 is located on the top of the placement component 2 and is provided with a moving unit 5 for driving the cutting component 6 to move, and the moving unit 5 can enable the cutting component 6 to move in the horizontal direction and the vertical direction, so that the cutting component 6 can adapt to the chamfering operation of acrylic plates of different sizes.

[0033] In some embodiments, the moving unit 5 includes a horizontal moving component 51 and a lifting component 52. The horizontal moving component 51 can move the cutting component 6 in the horizontal direction, so that the cutting component 6 moves along the circumference of the acrylic plate, and the lifting component 52 can lift and lower the cutting component 6, thereby moving the cutting component 6 to different heights to chamfer the acrylic plate.

[0034] In fact, the lifting component 52 can be horizontally moved on the horizontal moving component 51, or the horizontal moving component 51 can be lifted and lowered on the lifting component 52, both of which can realize the horizontal and vertical movement of the cutting component 6.

[0035] Specifically, the lifting component 52 is an electric telescopic rod, and the horizontal moving component 51 is a horizontal sliding rod 512 and a sliding member 511 slidably arranged on the horizontal sliding rod 512 , a vertical sliding rod 513 and a driving member 514 slidably arranged on the vertical sliding rod 513 .

[0036] In fact, see Figure 2 The cutting assembly 6 includes a cutter head unit 62 and a rotating unit 61 that drives the unit to rotate. When the chamfering operation is performed, the rotating unit 61 drives the cutter head unit 62 to chamfer the peripheral side of the acrylic plate. Specifically, the rotating unit 61 is a motor.

[0037] In some embodiments, the cutter head unit 62 includes a connecting member 621, a cutting knife 625, a fixing member 623, and a reset member disposed inside the connecting member 621. The cutting knife 625 is detachably disposed on the connecting member 621, and the cutting surface of the cutting knife 625 is located on the rotating side of the cutter head unit 62. The fixing member 623 is sleeved on the outside of the connecting member 621 and fixes the cutting knife 625. A fixing hole 6231 is provided on the fixing member 623, and the reset member is loosely matched with the fixing hole 6231. Specifically, the reset member is composed of two special-shaped buttons 624 and a return spring 622 in the connecting member 621, and limiting grooves 6211 are provided on both sides of the connecting member 621 to limit the special-shaped buttons 624, and the return spring 622 in contact with the two special-shaped buttons 624 is always in a compressed state.

[0038] In fact, see Figure 3 A matching groove is provided at the bottom of the connecting member 621, and the matching groove matches with the bottom of the cutting knife 625. The head of the cutting knife 625 is 2-3mm higher than the connecting member 621. The bottom surface of the cutting knife 625 is flush with the bottom surface of the connecting member 621. The fixing member 623 matches with the connecting member 621. The wall thickness of the fixing member 623 is 1mm. During assembly, the inner bottom surface of the fixing member 623 contacts with the bottom surface of the connecting member 621, thereby further positioning the cutting knife 625 inside the connecting member 621.

[0039] In fact, when the fixing part 623 fixes the cutting knife 625 in the connecting part 621, the special-shaped button 624 is pushed into the fixing hole 6231 on the fixing part 623 by the return spring 622, fixing the fixing part 623 and making the cutting knife 625 completely fixed. In fact, there are two beveled surfaces on the top of the special-shaped button 624, which correspond to the beveled angle on the top of the fixing part 623 and the beveled angle in the fixing hole 6231 of the fixing part 623. When assembling the cutting knife 625, first install the cutting knife 625 into the matching groove of the connecting part 621, and then assemble the fixing part 623 and the connecting part 621 together. The beveled angle on the top of the fixing part 623 can be slowly pressed down along the beveled surface on the bottom of the button top, and the special-shaped button 624 is pressed into the rotating part. When the fixing part 623 is inside, the beveled angle on the top of the fixing part 623 can be slowly pressed down along the beveled angle on the bottom of the button top, and the special-shaped button 624 is pressed into the rotating part. When the bottom surface contacts the bottom surface of the knife connecting member 621, the special-shaped button 624 is pushed into the fixing groove of the fixing member 623 by the return spring 622. When replacing the cutting knife 625, the upper inclined surface of the top of the special-shaped button 624 can be pressed into the fixing member 623 by hand, and then the fixing member 623 is pulled down to make the fixing member 623 match the inclined surface on the groove, and the special-shaped button 624 is pressed into the connecting member 621 along the upper inclined surface of the top of the special-shaped button 624, and then the fixing member 623 and the cutting knife 625 are taken out. Specifically, the fixing hole 6231 on the fixing member 623 is a U-shaped hole, which can facilitate the finger to press the button into the fixing member 623 groove.

[0040] In some embodiments, the base 1 is provided with an adsorption unit 21 located at the placement component 2 for adsorbing and fixing the acrylic plate.

[0041] In practice, the acrylic sheet is placed on the adsorption unit 21 , the adsorption unit 21 is turned on, and the air inside the adsorption unit 21 is evacuated so that the external air pressure is greater than the air pressure inside the adsorption unit 21 , thereby fixing the acrylic sheet on the adsorption unit 21 .

[0042] In some embodiments, the base 1 is located outside the adsorption unit 21 and is slidably provided with multiple push plates 22, and the base 1 is provided with a push member 4 for driving the push plates 22 to slide laterally; the top placement surface of the multiple push plates 22 is in the same horizontal plane as the top of the adsorption unit 21.

[0043] In fact, the acrylic plate is placed on the adsorption unit 21, and the pushing member 4 pushes the pushing plate 22 to move the pushing plate 22 to the side of the acrylic plate, and the bottom surface of the groove where the pushing plate 22 is placed is in sliding contact with the acrylic plate, so that when processing the acrylic plate, the pushing plate 22 supports the acrylic plate to prevent the acrylic plate from being deformed during processing.

[0044] See also Figure 4 A plurality of push plates 22 are arranged on the base 1 to form an adjustable placement surface, and the adjustable placement surface is used to adapt to acrylic plates of different specifications.

[0045] In fact, the pusher 4 on the base 1 drives the push plates 22 around the adsorption unit 21 to move inward, and the side surface of the top placement surface of the push plate 22 contacts the side edge of the acrylic plate, thereby fixing the four sides of the acrylic plate to prevent the acrylic plate from shifting during processing.

[0046] In some embodiments, the horizontal moving component 51 includes two parallel horizontal slide rods 512 and a vertical slide rod 513 perpendicular to the horizontal slide rod 512 , and both ends of the vertical slide rod 513 are respectively slidably set on the two horizontal slide rods 512 , and the cutting component 6 is slidably set on the vertical slide rod 513 .

[0047] In fact, when processing the acrylic plate, a sliding member 511 is slidably arranged on the horizontal sliding rod 512, and the sliding member 511 is connected to the vertical sliding rod 513. The sliding member 511 controls the vertical sliding rod 513 to drive the cutting assembly 6 along the direction of the horizontal sliding rod 512 to process the side of the acrylic plate parallel to the horizontal sliding rod 512. The driving member 514 slidably arranged on the vertical sliding rod 513 drives the cutting assembly 6 along the direction of the vertical sliding rod 513 to process the side of the acrylic plate parallel to the vertical sliding rod 513.

[0048] In some embodiments, the lifting component 52 is slidably set on the vertical slide rod 513, and the cutting component 6 is located on the lifting and moving component, and the lifting and moving direction of the cutting component 6 is perpendicular to the vertical slide rod 513 and the horizontal slide rod 512.

[0049] In fact, the size of the chamfer can be changed by adjusting the lifting position of the cutting assembly 6 through the lifting assembly 52. ​​The cutting assembly 6 can chamfer square or rectangular acrylic plates of different specifications through the vertical sliding rod 513 and the horizontal sliding rod 512.

[0050] In some embodiments, a cooling component 3 for cooling the cutting component 6 is disposed on the lifting component 52 .

[0051] In fact, when the acrylic plate is chamfered, the nozzle of the cooling component 3 sprays the cooling liquid toward the cutting blade 625, and the cooling component 3 moves synchronously with the cutting component 6, so that the cooling component 3 continuously cools the cutting blade 625. Specifically, the cooling component 3 is a cooling pipe.

[0052] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims.
