[0072] In addition, the technical features involved in the different embodiments of the application described below can be combined with each other as long as there is no conflict between them.

[0073] The technical solutions of the embodiments of the present application are described in detail below with reference to the drawings.

[0074] As Figures 1 to 3 shown, the single-motor tracking trimming mechanism provided by the embodiment of the present application comprises a moving assembly 1 which can move up and down and horizontally;

[0075] A tracking motor 2 is connected with a tracking knife 3 on the motor shaft.

[0076] The angle adjusting assembly 4 comprises an adjusting plate 41, a horizontal adjusting part 42 and a vertical adjusting part 43, the adjusting plate 41 is arranged on the moving assembly 1, the adjusting plate 41 is provided with an arc-shaped groove 411 and two slits 412 extending along the axial direction of the motor shaft, the slits 412 are communicated with the arc-shaped groove 411, and the slits 412 and the arc-shaped groove 411 jointly divide the adjusting plate 41 into an outer plate 413 and an inner plate 414, and the tracking motor 2 is arranged on the inner plate 414.

[0077] The horizontal adjusting part 42 is used for adjusting the deflection angle of the tracking cutter 3 in the horizontal direction.

[0078] The vertical adjusting part 43 is used for adjusting the deflection angle of the tracking cutter 3 in the vertical direction.

[0079] The moving assembly 1 is installed on the machine table of the edge sealing machine, and can move up and down and move horizontally along the profile (i.e. the direction in which the edge sealing machine conveys the plate 100) on the edge sealing machine. After the plate 100 is conveyed to the designated working position, the tracking motor 2 follows the moving assembly 1 to perform corresponding actions on the four corners of the plate 100 in turn during the movement of the plate 100.

[0080] Specifically, the slits 412 and the arc-shaped groove 411 divide the adjusting plate 41 into an outer plate 413 and an inner plate 414, the first end of the inner plate 414 is connected with the outer plate 413, and the second end is a free end, the second end can swing in the slit 412 when subjected to a horizontal force, so as to adjust the deflection angle of the tracking motor 2 in the horizontal direction, and the second end can slightly bend in the vertical direction when subjected to a vertical force, so as to adjust the deflection angle of the tracking motor 2 in the vertical direction, and under the action of the horizontal adjusting part 42 and the vertical adjusting part 43, the purpose of independently fine-tuning the tracking cutter 3 without interfering with other components is achieved.

[0081] The adjusting plate 41 can be made of plastic material, which can balance the tensile strength and yield strength, so as to ensure that the adjusting plate 41 can bend under stress and avoid the risk of breaking. The slits 412 and the arc-shaped groove 411 can be constructed by means of water jet cutting, cutting and the like.

[0082] Compared with the prior art, the single-motor tracking edge trimming mechanism can independently change the axial direction of the tracking motor 2 through the angle adjusting assembly 4, and then adjust the cutting surface of the tracking cutter 3, so as to ensure the machining precision of the tracking cutter 3.

[0083] As Figure 2 and Figure 3As shown, in order to improve the movability of the inner plate 414 and reduce the stress requirement of the inner plate 414, in a preferred embodiment, the slit 412 of the single-motor tracking trimming mechanism is recessed inward to form a bending groove 415 along the width direction of the adjusting plate 41 away from one end of the arc-shaped groove 411. The first end of the slit 412 communicates with the arc-shaped groove 411, and a U-shaped groove is formed between the slit 412 and the arc-shaped groove 411. The first end of the slit 412 is recessed inward to form the bending groove 415, which can reduce the connection strength between the inner plate 414 and the outer plate 413 and reduce the maximum stress requirement of the inner plate 414.

[0084] In the present embodiment, the skilled person in the art can set the groove width of the arc-shaped groove 411 and the slit width of the slit 412 according to the actual use, which is not specifically described here.

[0085] Further, the horizontal adjusting member 42 of the single-motor tracking trimming mechanism includes two adjusting screws, and screw holes communicating with the arc-shaped groove 411 are arranged on both sides of the outer plate 413 along the width direction of the adjusting plate 41. When the adjusting screws are tightly fastened with the outer plate 413, the end of the adjusting screw is in contact with the inner plate 414.

[0086] The vertical adjusting member 43 includes an adjusting shaft 431, a connecting seat 432, and a butterfly spring 433.

[0087] The connecting seat 432 is fixedly installed on the bottom end face of the outer plate 413, one end of the connecting seat 432 is opposite to the inner plate 414, and the inner plate 414 is provided with a threaded hole for screwing the adjusting shaft 431.

[0088] The butterfly spring 433 is sleeved on the adjusting shaft 431 and located between the connecting seat 432 and the inner plate 414.

[0089] Specifically, the tracking motor 2 is installed on the inner plate 414, and after two sets of adjusting screws are matched with threaded holes on the outer plate 413, they abut against the wall surface of the inner plate 414. By adjusting the feeding degree of the two sets of adjusting screws, the deflection angle of the tracking cutter 3 in the horizontal direction can be finely adjusted. The connecting seat 432 is connected and fixed with the outer plate 413. The adjusting shaft 431 is provided with external threads, and the adjusting shaft 431 and the connecting seat 432 are oppositely arranged and threadedly matched with the inner plate 414. The adjusting shaft 431 is in contact with the connecting seat 432 through the butterfly spring 433, and when one end of the adjusting shaft 431 protrudes from the inner plate 414 and abuts against the tracking motor 2, support is provided by the butterfly spring 433 and the connecting seat 432. By rotating the adjusting shaft 431, the deflection angle of the tracking cutter 3 in the vertical direction relative to the adjusting plate 41 can be changed. By adjusting the screws and the adjusting shaft 431 respectively or simultaneously, the axis direction of the tracking cutter 3 can be changed, so that the axis of the tracking cutter 3 is parallel to the axis of the profiling die 134. For example, when the axis of the tracking cutter 3 is inclined to the left relative to the axis of the profiling die 134, the left adjusting screw is first screwed out, the right adjusting screw is screwed in, and then the left adjusting screw is screwed in to be fixed, so as to adjust the axis of the tracking cutter 3 to be inclined to the right by a certain angle; when the axis of the tracking cutter 3 is inclined in the vertical direction relative to the axis of the profiling die 134, the adjusting shaft 431 is rotated to change the threaded feeding depth of the adjusting shaft 431 and the inner plate 414, so as to offset the axis of the tracking cutter 3 in the vertical direction by a certain angle.

[0117] The first limiting wheel 71 is rotationally connected with the vertical sliding seat 122 through a rotating shaft, the axis of the first limiting wheel 71 is parallel to the axial direction of the motor shaft, the limiting seat 72 is arranged on the pressing beam of the edge sealing machine, the limiting seat 72 abuts against the outer periphery of the first limiting wheel 71, and the inductive switch 73 is located on one side of the first limiting wheel 71 and is used for sensing the relative position of the limiting seat 72;

[0118] The second limiting assembly 8 comprises a second limiting wheel 81 and a limiting block 82, the second limiting wheel 81 is rotationally connected with the limiting block 82 through a rotating shaft, and the limiting block 82 is fixedly arranged on the pressing beam of the edge sealing machine;

[0119] The guiding sliding seat 52 is provided with a positioning block 83 opposite to the second limiting wheel 81, the positioning block 83 has an inclined guiding surface abutting against the second limiting wheel 81; after the output shaft of the horizontal cylinder 111 is contracted to a certain extent, the guiding inclined surface of the positioning block 83 abuts against the second limiting wheel 81, the output shaft of the guiding cylinder 51 is contracted under the joint action of the positioning hole 83 and the second limiting wheel 81, and the guiding sliding seat 52 moves downwards. Therefore, when the output shaft of the horizontal cylinder 111 is contracted to the limit, if the contraction speed of the guiding cylinder 51 is slow due to air pressure or the like, or the guiding cylinder 51 cannot be contracted in time due to errors in the numerical control program of the edge sealing machine, the continuous advancement of the plate 100 will knock against the guiding sliding seat 51, and the plate 100 is damaged, therefore, the second limiting assembly 8 can effectively prevent the problem of plate knocking;

[0120] The horizontal cylinder 111, the vertical cylinder 121, the guiding cylinder 51 and the swing cylinder 61 are all provided with magnetic switches

[0121] The working process of the single-motor tracking trimming mechanism is as follows:

[0122] After the edge banding machine is started, the plate 100 is conveyed to the conveying system of the edge banding machine, the single motor tracking cutter 3 starts to move, the horizontal cylinder 111, the vertical cylinder 121 and the output shaft of the guide cylinder 51 are advanced, the magnetic switch at the head of the horizontal cylinder 111 and the magnetic switch at the head of the guide cylinder 51 are on, the swing cylinder 61 and the advance and retreat cylinder 133 are retracted, and the first limiting wheel 71 is close to the lower surface of the limiting seat 72. The plate 100 is conveyed on the edge banding machine from right to left, when the front end of the plate 100 reaches the position of the single motor tracking cutter 3, the left side of the plate 100 contacts the guide wheel 53, the plate 100 pushes the guide wheel 53 and the tracking cutter 3 to the left synchronously, and the simultaneous action of the swing cylinder 61, the advance and retreat cylinder 133 and the horizontal cylinder 111 makes the guide wheel 53 always close to the left side of the plate 100. At this time, the profiling wheel 135 is located at the upper left corner of the plate 100. After the output shaft of the horizontal cylinder 111 is retracted to a certain distance, the magnetic switch at the head of the horizontal cylinder 111 is off, the swing cylinder 61 is first changed to the advanced state, the magnetic switch at the head of the swing cylinder 61 is on after the swing cylinder 61 is advanced to a certain distance, and the swing cylinder 61 returns to the retracted state, at the same time, the vertical cylinder 121 pulls down the tracking cutter 3, and the left upper corner and the left lower corner of the plate 100 are processed in turn. The state of the tracking cutter 3 in the process of trimming the plate 100 is shown in Figure 8 , and the position relationship of the guide wheel 53, the profiling wheel 135 and the plate 100 in the action process is shown in Figure 9 .

[0123] When the magnetic switch light of the tail of the vertical cylinder 121 is on, the processing action of the tracking knife 3 to the left lower corner of the plate 100 is finished, that is, after the vertical cylinder 121 pulls the tracking knife 3 away from the plate 100, the output shaft of the guide cylinder 51 is retracted, the guide wheel 53 is pulled down to separate from the plate 100, the horizontal cylinder 111 first pushes the guide wheel 53 and the tracking knife 3 to the right to return to the initial position synchronously, the magnetic switch light of the head of the horizontal cylinder 111 is on, at this time, the output shaft of the swing cylinder 61 becomes the pushing state, the output shaft of the guide cylinder 51 is extended, the guide wheel 53 is pushed up, after the magnetic switch light of the head of the guide cylinder 51 is on, the output shaft of the horizontal cylinder 111 is retracted, the guide wheel 53 and the tracking knife 3 are moved to the left synchronously, until the guide wheel 53 is close to the right side of the plate 100. At this time, the profiling wheel 135 is located at the right lower corner of the plate 100. After the output shaft of the horizontal cylinder 111 is retracted to a certain distance, the magnetic switch light of the head of the horizontal cylinder 111 is off, the swing cylinder 61 first becomes the retraction state, after the swing cylinder 61 is retracted to a certain distance, the magnetic switch light of the tail of the swing cylinder 61 is on, the swing cylinder 61 is restored to the pushing state, at the same time, the vertical cylinder 121 pushes the tracking knife 3 up, and the right lower corner and the right upper corner of the plate 100 are processed in turn. When the limit seat 72 is sensed by the inductive switch 73, the first limit wheel 71 is close to the lower surface of the limit seat 72, the processing action of the tracking knife 3 to the right upper corner of the plate 100 is finished, that is, after the vertical cylinder 121 pulls the tracking knife 3 away from the plate 100, the output shaft of the horizontal cylinder 111 is pushed, the guide wheel 53 and the tracking knife 3 are pushed to the right synchronously, the output shaft of the swing cylinder 61 becomes the retraction state, the magnetic switch light of the head of the horizontal cylinder 111 is on, and one working cycle is finished.

[0124] The positional relationship of the guide wheel 53, the profiling wheel 135 and the plate 100 from the position where the processing of the left lower corner of the plate 100 is finished to the position where the processing of the right upper corner is finished is shown in the figure.
