[0069] After edge banding with edge banding tape, the board 500 still needs to undergo fine edge trimming. Existing edge trimming mechanisms are bulky and difficult to integrate into small edge banding machines. In addition, existing edge trimming mechanisms are prone to wobbling when trimming perforated board 500.

[0070] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0071] like Figures 1 to 4 As shown, the present invention provides a suspended scraping mechanism, including a mounting frame 1, on which a scraping blade 2 and an auxiliary positioning unit 3 are provided;

[0072] The longitudinal scraping unit 4 is vertically mounted on the mounting frame 1;

[0073] The horizontal scraping unit 5 is horizontally set on the mounting frame 1. The horizontal scraping unit 5 and the vertical scraping unit 4 form a scraping station for trimming the plate 500.

[0074] The scraping knife 2 is located on the scraping station, and the reference surface of the auxiliary positioning unit 3 coincides with the scraping surface of the longitudinal scraping unit 4.

[0075] When the technical scheme of the utility model is applied to the edge banding machine, the mounting rack 1 is slidably mounted on the pressing beam 100 and the guide rail 200 of the edge banding machine, and the suspension type edge scraping mechanism on the pressing beam 100 and the suspension type edge scraping mechanism on the guide rail 200 can slide relative to each other so as to adjust according to the size of the actual plate 500.

[0076] Specifically, the longitudinal edge scraping unit 4 and the transverse edge scraping unit 5 form an edge scraping station capable of accommodating the sliding of the plate 500, and the edge scraping knife 2 is located on the edge scraping station, and the plate 500 is in close contact with the edge scraping knife 2 when sliding on the edge scraping station, thereby realizing the edge scraping work of the plate 500. Two suspension type edge scraping mechanisms are installed on the edge banding machine, which are opposite to each other and mirror-symmetrical. During the sliding process of the plate 500, the upper and lower surfaces of the plate 500 are pressed by the longitudinal edge scraping unit 4 on the pressing beam 100 and the guide rail 200, that is, the plane of the plate 500 is in the same horizontal plane as the reference surface of the longitudinal edge scraping unit 4, and one side surface of the plate 500 is in close contact with the transverse edge scraping unit 5, thereby realizing the edge scraping treatment during the movement of the plate 500 driven by the edge banding machine. Generally, the surface of the plate 500 will have various hole and groove structures. When the longitudinal edge scraping unit 4 falls into the hole and groove structure, the surface of the plate 500 changes, so that the reference surface of the longitudinal edge scraping unit 4 is not in the same horizontal plane as the surface of the plate 500, causing the plate to shake and affecting the edge scraping work of the subsequent edge scraping knife 2. By providing the auxiliary positioning unit 3, the reference surface of the auxiliary positioning unit 3 coincides with the reference surface of the longitudinal edge scraping unit 4. When the longitudinal edge scraping unit 4 encounters the hole and groove structure, the reference surface of the auxiliary positioning unit 3 can ensure that the relative position of the plate 500 does not change, so that they can be in the same horizontal plane, and the collision between the plate 500 and the longitudinal edge scraping unit 4 is avoided.

[0077] In some embodiments, referring to Figure 3 and Figure 4 , and in combination with Figure 6 , the auxiliary positioning unit 3 comprises a connecting piece 30 and a rolling piece 31, the two sides of the longitudinal edge scraping unit 4 are each provided with a connecting piece 30, and the rolling piece 31 is connected to the connecting piece 30, and the rolling piece 31 is in rolling contact with the plate 500. Specifically, the auxiliary positioning unit 3 can be composed of a bearing seat, a bearing and a connecting shaft, which is fixed on the first adjusting seat 42 through a long hole, and the rolling surface of the bearing coincides with the rolling surface of the longitudinal edge scraping unit 4. Correspondingly, the auxiliary positioning unit 3 can also be set in the form of ball rolling.

The longitudinal guide wheel 41 is installed on the second adjusting seat 52 in the same way. The adjusting screw 43 passes through the first adjusting seat 42 and is screwed into the scraper seat 13. The auxiliary positioning units 3 are located on both sides of the first adjusting seat 42. Tightening the adjusting screw 43 controls the vertical sliding distance of the first adjusting seat 42, thereby controlling the relative position between the longitudinal scraping unit 4 and the scraping knife 2.

[0097] The output end of the first cylinder 55 passes through the first cylinder seat 56 and is screwed with the first adjusting shaft 54, the first adjusting seat 42 is connected with the second adjusting seat 52, the limiting block 58 is fixed on the first cylinder seat 56, the second adjusting seat 52 is clamped with the limiting block 58, so that the movement of the second adjusting seat 52 is limited in the limiting block 58. When the output end of the first cylinder 55 extends, the first adjusting seat 42 moves forward relative to the first cylinder 55, the first adjusting seat 42 moves forward and abuts against the limiting block 58, when the output end of the first cylinder 55 retracts, the second adjusting seat 52 moves backward and abuts against the first adjusting shaft 54 after moving a certain stroke, so as to limit the stroke of the first adjusting seat 42 in the reciprocating movement and control the movement stroke of the transverse guide wheel 51. The first adjusting shaft 54 is screwed with the output end of the first cylinder 55, the rotation of the first adjusting seat 42 and the screwing depth of the output end of the first cylinder 55 can adjust the distance between the second adjusting seat 52 and the scraper seat 13, so as to control the distance between the transverse guide wheel 51 and the edge scraping knife 2 and adjust the edge scraping range of the plate 500.

[0098] In a preferred embodiment, please refer to Figure 8 and Figure 9 and in combination with Figure 11 The first sliding seat 11 of the suspension type edge scraping mechanism comprises a first sliding seat 110, a third optical axis 111, an adjusting plate 112 and a spring 113.

The adjusting plate 112 is installed on the first sliding seat 110. The bolt 114 is screwed into the threaded hole corresponding to the lower fixed seat 400 through the mounting hole of the spring 113 and the adjusting plate 112. The adjusting plate 112 is further provided with a machine screw hole (not shown). A long machine screw is inserted into the machine screw hole.
