[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] See also Figure 12-14 The present invention provides a technical solution for an integrated high-precision double-end chamfering device: an integrated high-precision double-end chamfering device, comprising a baffle 9 installed on a plate edge banding machine frame and a double-end chamfering assembly for chamfering plate strips, the double-end chamfering assembly comprising a tool housing 4 and an inner positioning ring 42 connected to the front surface of the tool housing 4, the outer side edge of the inner positioning ring 42 has a bevel, which is convenient for contact with the plate and better tightness, the inner positioning ring 42 and the tool housing 4 are rotatably connected through a ball bearing 47, a chamfering motor 45 is provided on the rear side of the tool housing 4, a rotating rod is provided at the output end of the chamfering motor 45, and one end of the rotating rod passes through the middle of the tool housing 4 and extends to the front side thereof and is connected to a guide wheel 41, a chamfering cutter 44 is fixedly installed on the rotating rod at one side adjacent to the guide wheel 41, an outer side surface of the guide wheel 41 is provided with an outer positioning ring 43, and the guide wheel 41 and the outer positioning ring 43 are provided on the outer side of the guide wheel 41. The positioning rings 43 are connected to one end of the rotating rod through ball bearings. The guide wheel 41 is an elliptical structure. When the double-end chamfering assembly is under the plate, the guide wheel 41 is blocked by the baffle 9, so that the guide wheel 41 is in a horizontal or elevated state (when facing the plate). This makes it convenient for the plate to be transported under the guide wheel 41, thereby pushing the guide wheel 41 and the outer positioning ring 43. At this time, the outer positioning ring 43 just rolls on the upper end of the plate strip, while the inner positioning ring 42 presses on the side of the plate strip. The outer positioning ring 43 and the inner positioning ring 42 can be used to simultaneously press the upper surface and the side of the plate strip to ensure the stability of the chamfering cutter 44 when cutting the chamfers at both ends of the plate strip. In addition, the outer positioning ring 43 and the inner positioning ring 42 rotate with the plate during contact with the plate, which can ensure smoothness during movement and reduce jitter.

[0051] like Fig.14 As shown, the tool housing 4 is a hollow structure, and the lower end of the rear side of the tool housing 4 is connected to a dust suction pipe 46, and the chamfering cutter 44 is located on the front side of the tool housing 4. The tool housing 4 is designed to be hollow, with its upper end located at the chamfering cutter 44, and the lower end connected to an external dust suction device through a dust suction pipe 46, so that when the chamfering cutter 44 cuts and chamfers the two ends of the sheet strip, the cut waste can be sucked away.

[0052] like Figure 1-3As shown, the integrated high-precision double-end chamfering device of the present design also includes a lateral adjustment mechanism 1, which is installed on the frame of the plate edge banding machine and is used to adjust the lateral position of the double-end chamfering component during operation. The lateral adjustment mechanism 1 includes a mounting plate 11 fixed to the frame of the plate edge banding machine. A lateral drive motor 12 is arranged on the rear side of the mounting plate 11. The output end of the lateral drive motor 12 is connected to a main gear 13. A reducer is also arranged between the lateral drive motor 12 and the main gear 13. The main gear 13 is horizontally connected to a driven gear 15 through a toothed belt 14. Both sides of the driven gear 15 The center is fixed to the frame of the plate edge banding machine through a connecting rod, and the connecting rod is connected to the driven gear 15 for rotation. During the working process, when the plate strip is tracked and chamfered, the main gear 13 is driven to rotate by the lateral driving motor 12, and then the driven gear 15 is driven to rotate synchronously by the toothed belt 14. Therefore, the main gear 13 and the driven gear 15 can support the toothed belt 14 to rotate, and the rotation of the toothed belt 14 is used to drive the vertical adjustment mechanism 2 and the double-end chamfering assembly to move with the plate through the fixed clamping plate 16, so as to facilitate the chamfering cutter 44 to realize the tracking chamfering operation;

[0053] like Figure 5 and 6 As shown, a fixed splint 16 is installed on the toothed belt 14, and a tracking cylinder 6 is connected to one side of the fixed splint 16. A connecting seat 61 is fixed on the cylinder barrel of the tracking cylinder 6, and the telescopic end of the tracking cylinder 6 is fixed to the side of the fixed splint 16. The purpose of adding the tracking cylinder 6 is to eliminate the tracking error of the double-end chamfering assembly during the chamfering operation, and ensure the stable pressure of the double-end chamfering assembly on the plate. In the process of tracking and chamfering the front end of the plate strip, under the pushing force of the tracking cylinder 6, it is beneficial to maintain the pressure between the front end of the plate strip and the positioning ring, thereby improving the chamfering accuracy and buffering the impact force of the plate on the double-end chamfering assembly at the moment of contact. When chamfering the tail end of the tracking plate strip, the contraction force of the tracking cylinder 6 is beneficial to the positioning ring to press the tail end of the plate strip, thereby reducing the synchronization error between the tracking speed of the double-end chamfering assembly and the forward speed of the plate, and improving the chamfering accuracy. It should be supplemented that the tracking cylinder 6 and the clamping cylinder 32 both adopt existing conventional cylinders.

[0054] like Figure 3 and 4As shown, the transverse adjustment mechanism 1 also includes two transverse slide rails 17 fixed to the frame of the plate edge banding machine, and an L-shaped fixing plate 19 is slidably connected to the two transverse slide rails 17. Two transverse slide seats 18 are installed at the front side of the L-shaped fixing plate 19 corresponding to the two transverse slide rails 17. The L-shaped fixing plate 19 slides on the transverse slide rail 17 through the transverse slide seat 18. When the transverse adjustment mechanism 1 is working, the L-shaped fixing plate 19 will be driven to move on the two transverse slide rails 17 through the fixed clamping plate 16 and the connecting seat 61, and the L-shaped fixing plate 19 will simultaneously drive the vertical adjustment mechanism 2 to move transversely, and the lower end of the L-shaped fixing plate 19 is fixed to the upper end surface of the connecting seat 61 (as shown in FIG. Figure 6 As shown in the figure, the upper end of the L-shaped fixing plate 19 and the two transverse slide rails 17 are used for sliding positioning, which can ensure the connection stability of the fixing clamping plate 16 on the toothed belt 14, and also facilitate the stability of the tracking cylinder 6 when in use, so as to avoid the fixing clamping plate 16, the connecting seat 61 and the L-shaped fixing plate 19 having a large bearing force on the toothed belt 14, which causes the toothed belt 14 to be deformed greatly and affects the vertical operation of the double-end chamfering assembly;

[0055] like Figure 3 , 5 As shown in Figure 7, the integrated high-precision double-end chamfering device of the present design also includes a vertical adjustment mechanism 2, which is arranged on the lateral adjustment mechanism 1 and is used to adjust the vertical position of the double-end chamfering component during operation. The vertical adjustment mechanism 2 includes a vertical drive motor 21 installed at the lower end of the rear side of the L-shaped fixing plate 19 and a vertical positioning plate 24 on the rear side of the L-shaped fixing plate 19. A vertical slide rail 25 is installed on the front surface of the vertical positioning plate 24. A vertical slide seat 26 is installed at the rear side surface of the L-shaped fixing plate 19 corresponding to the vertical slide rail 25. The vertical positioning plate 24 slides on the vertical slide seat 26 through the vertical slide rail 25. The output end of the vertical drive motor 21 is connected to a vertical drive gear 22. A rack plate 23 is vertically installed on one side of the positioning plate 24, and the teeth on the surface of the rack plate 23 mesh with the teeth on the surface of the vertical driving gear 22. During the operation of the double-end chamfering assembly, the vertical driving motor 21 is controlled to work in the forward direction to drive the vertical driving gear 22 to rotate. The rotation of the vertical driving gear 22 will cause the rack plate 23 to drive the vertical positioning plate 24 to rise. When the vertical positioning plate 24 rises, it will rise vertically in the vertical slide seat 26 through the vertical slide rail 25. From this, the double-end chamfering assembly can be driven to move upward through the L-shaped connecting plate 31, and vice versa, the double-end chamfering assembly can be driven to move downward, thereby realizing the lifting and lowering adjustment of the double-end chamfering assembly.

[0056] like Figure 8 and 9As shown, the vertical adjustment mechanism 2 also includes an L-shaped connecting plate 31 installed on the rear side of the vertical positioning plate 24, a U-shaped groove is formed between the L-shaped connecting plate 31 and the vertical positioning plate 24, two limit rods are symmetrically installed in the U-shaped groove between the L-shaped connecting plate 31 and the vertical positioning plate 24, and a lateral adjustment seat 33 is slidably connected to the two limit rods; a clamping cylinder 32 is installed on the rear side of the L-shaped connecting plate 31, and the telescopic end of the clamping cylinder 32 passes through the L-shaped connecting plate 31 and extends to the U-shaped groove and is fixed to the rear side of the lateral adjustment seat 33. When the retracted end is extended, it will push the lateral adjustment seat 33 to slide toward the vertical positioning plate 24 on the two limit rods. The purpose of adding the clamping cylinder 32 is: during the operation, the L-shaped connecting plate 31 can be pushed closer to the plate by the extension and retraction of the clamping cylinder 32, so that the inner positioning ring 42 can press the side of the plate. Since the edge of the inner positioning ring 42 of the double-end chamfering assembly has a bevel, it is convenient for the plate to squeeze the inner positioning ring 42, thereby realizing the clamping and accurate positioning of the plate and the inner positioning ring 42, which is beneficial to improving the positioning accuracy and improving the chamfering accuracy and quality of the product.

[0057] like Fig.10 and 11 As shown, the integrated high-precision double-end chamfering device of the present design also includes a cutter head adjustment component 3, which is connected to the vertical adjustment mechanism 2. Before use, the double-end chamfering component can be adjusted in the horizontal and vertical dimensions. The cutter head adjustment component 3 includes a vertical positioning seat 7 fixed to the middle of the outer side surface of the horizontal adjustment seat 33. The vertical positioning seat 7 is L-shaped, and a vertical adjustment screw 71 passes through the top of the vertical positioning seat 7. A knob is provided on the top of the vertical adjustment screw 71. The bottom end of the vertical adjustment screw 71 is rotatably connected to a lifting plate 72, and the side of the lifting plate 72 is slidably connected to the vertical positioning seat 7, the vertical adjustment screw 71 is threadedly connected to the top of the vertical positioning seat 7. Before the entire device is used, the position of the chamfering cutter 44 can be adjusted according to the size of the plate. When adjusting in the vertical direction, the knob can be turned to drive the vertical adjustment screw 71 to rotate. When the vertical adjustment screw 71 rotates, since it is threadedly connected to the top of the vertical positioning seat 7, it will drive the lifting plate 72 to rise along the side of the vertical positioning seat 7, and the lifting plate 72 will drive the chamfering motor 45 and the chamfering cutter 44 to move upward, so as to facilitate the adjustment of the position of the chamfering cutter 44 on the tool housing 4.

[0058] like Fig.11As shown, the cutter head adjustment assembly 3 also includes a mounting plate 8 fixed to the other side of the lifting plate 72, and a positioning slide bar is symmetrically installed on the rear side of the mounting plate 8, and a guide seat 83 is slidably connected to the two positioning slide bars, and a lateral adjustment screw 81 is penetrated and connected to the middle part of the guide seat 83, and a knob is also provided at one end of the lateral adjustment screw 81, and the lateral adjustment screw 81 is rotatably connected to the guide seat 83, and one end of the lateral adjustment screw 81 penetrates the mounting plate 8 and is threadedly connected thereto, and a groove for the extension of the lateral adjustment screw 81 is also provided at the side of the lifting plate 72 corresponding to the lateral adjustment screw 81; a motor slide rail 82 is fixedly connected to the bottom end of the guide seat 83, and one end of the motor slide rail 82 is vertically fixed to the guide seat 83, and the upper surface of the motor slide rail 82 is slidably connected to the lower surface of the lifting plate 72, and the bottom of the motor slide rail 82 is fixed to the chamfering motor 45;

[0059] When it is necessary to adjust the lateral position of the chamfering cutter 44, that is, to adjust the distance that the chamfering cutter 44 extends out of the tool housing 4, the knob on the lateral adjustment screw 81 can be turned to screw it into the mounting plate 8 and extend it closer to the groove. At this time, the lateral adjustment screw 81 will move closer to the mounting plate 8 simultaneously with the guide seat 83. Since the guide seat 83 is slidably connected to the positioning slide bar, the stability of the guide seat 83 during movement can be ensured. When the guide seat 83 moves, it will drive the motor slide rail 82 to slide on the lower surface of the lifting plate 72, and the motor slide rail 82 will drive the chamfering motor 45 and the chamfering cutter 44 to adjust the lateral position in the tool housing 4.

[0060] like Figure 1 As shown, the integrated high-precision double-end chamfering device of the present design also includes a detection bracket 5 installed on the frame of the plate edge banding machine, and a detection probe 51 is installed on the front side of one end of the detection bracket 5. The detection probe 51 corresponds to the plate strip on the transmission roller of the plate edge banding machine. When the front end of the plate is transmitted in place, the detection probe 51 can send a signal to the control system of the plate edge banding machine, which controls the double-end chamfering device to track and chamfer the front end of the plate strip. When the plate is transmitted and the detection probe 51 cannot detect the plate, it will synchronously transmit a signal to the control system to control the double-end chamfering device to chamfer the rear end of the plate strip. It should be noted that the detection probe 51 can be used but not limited to an infrared probe or other industrial detection probes.

[0061] Working principle of the present invention: When in use, firstly, according to the size of the plate, the cutter head adjustment assembly 3 is used to adjust the horizontal position and vertical position of the chamfering cutter 44 in the cutter housing 4. After the adjustment is completed, the double-end chamfering device starts to work;

[0062] First, before the plate arrives, the double-end chamfering assembly is located below the plate, and the guide wheel 41 is always in a horizontal or elevated position under the obstruction of the baffle 9; and the chamfering cutter 44 is always in a rotating state.

[0063] When the front end of the plate is in place, the detection probe 51 will detect the plate, and the lateral adjustment mechanism 1 and the vertical adjustment mechanism 2 will start working. At this time, the front end of the plate contacts the guide wheel 41, and at the same time, the outer positioning ring 43 and the inner positioning ring 42 contact and press the upper surface and side of the plate strip. At this time, the lateral adjustment mechanism 1 drives the double-end chamfering assembly to rise, so that the chamfering cutter 44 moves from bottom to top. During the movement of the chamfering cutter 44 from bottom to top, the elliptical guide wheel 41 is simultaneously subjected to the extrusion force of the front end surface of the plate and rotates, and the elliptical guide wheel gradually becomes a vertical state; the side and front section of the plate are respectively positioned by the side of the inner positioning ring 42 and the outer positioning ring 43, and the chamfering cutter 44 contacts the right angle of the plate to achieve chamfering; while the chamfering cutter 44 moves from bottom to top and chamfers, the double-end chamfering device tracks the plate along the horizontal forward direction of the plate to achieve tracking chamfering;

[0064] When the chamfering cutter 44 moves to the top of the plate, that is, the chamfering of the front end of the plate strip is completed, the chamfering cutter 44 is separated from the plate, and the double-end chamfering device is driven by the lateral adjustment mechanism 1 to move backward, and the front end of the plate pushes the elliptical guide wheel 41 to rotate to a horizontal state;

[0065] When the tail end of the plate passes through the detection probe 51 and the detection probe 51 cannot detect any signal, according to the set spacing difference, that is, when the tail end of the plate to be chamfered is separated from the side of the elliptical guide wheel 41, the vertical adjustment mechanism 2 will drive the chamfering cutter 44 to move from top to bottom. During the movement of the chamfering cutter 44 from top to bottom, the elliptical guide wheel 41 is rotated by the extrusion force of the rear end surface of the plate, and the elliptical guide wheel gradually becomes a vertical state; the side and rear section of the plate are respectively positioned by the side of the inner positioning ring 42 and the outer positioning ring 43, and the chamfering cutter 44 contacts the rear end of the plate strip at a right angle to achieve chamfering; while the chamfering cutter 44 moves from top to bottom, the double-end chamfering device is driven by the lateral adjustment mechanism 1, and will track the plate along the horizontal forward direction of the plate to achieve tracking chamfering of the tail end of the plate.

[0066] When the chamfering cutter 44 moves to the bottom of the plate, that is, the chamfering of the rear end of the plate is completed, the chamfering cutter 44 is separated from the plate, and the elliptical guide wheel 41 is in a vertical state. The double-end chamfering device is driven by the lateral adjustment mechanism 1 to move backward and reset, and at the same time, it is driven by the vertical adjustment mechanism 2 to descend and reset. After resetting, the lower end of the elliptical guide wheel 41 is blocked by the baffle 9 and rotates to reset to a horizontal or elevation state;

[0067] In this way, the chamfering operation of the front and rear ends of the sheet strip can be completed. It should be noted that the contact process between the head or tail of the sheet and the chamfering cutter 44 is accompanied by the rotation of the elliptical guide wheel 41, and the feeding process of the chamfering cutter 44 is gradual. The gradual feeding at the same position is beneficial to the stability and smoothness of the chamfering, and the contact between the head or tail of the sheet and the positioning ring during the movement is flexible, which is beneficial to reduce jitter and improve the chamfering quality.

[0068] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
