[0036] The upper supporting wheel module 32 and the lower supporting wheel module 31 have the same structure, the upper supporting wheel module 32 is set upside down, and the lower supporting wheel module 31 is set up forward, and the wheel surface of an auxiliary supporting wheel of the upper supporting wheel module 32 contacts the side surface of the plate, and the wheel surface of another auxiliary supporting wheel contacts the edge of the upper end surface of the plate, and the wheel surface of one auxiliary supporting wheel of the lower supporting wheel module 31 contacts the side surface of the plate, and the wheel surface of another auxiliary supporting wheel contacts the edge of the lower end surface of the plate.

[0037] Specifically, the upper supporting wheel module 32 and the lower supporting wheel module 31 both include an auxiliary supporting wheel mounting frame 3101, a first auxiliary supporting wheel 3106 and a second auxiliary supporting wheel 3107. The first auxiliary supporting wheel 3106 is arranged on one side of the auxiliary supporting wheel mounting frame 3101 through a first auxiliary supporting wheel fixing stud 3112, and the second auxiliary supporting wheel 3107 is arranged on the other adjacent side of the auxiliary supporting wheel mounting frame 3101 through a second auxiliary supporting wheel fixing stud 3111. The wheel axles of the first auxiliary supporting wheel 3106 and the second auxiliary supporting wheel 3107 are perpendicular to each other.

[0038] As a preferred solution, a limiting groove 4 is provided on two adjacent sides of the auxiliary wheel mounting bracket 3101. Figure 4 As shown, a limiting groove is respectively provided on the upper side and the left side of the auxiliary wheel mounting bracket 3101, and an auxiliary wheel adjusting member 3109 is embedded in each limiting groove. The auxiliary wheel adjusting member 3109 is fixed to the auxiliary wheel mounting bracket 3101 through the auxiliary wheel adjusting member position fastener 3104, and the hole provided on the auxiliary wheel mounting bracket 3101 for the auxiliary wheel adjusting member position fastener 3104 to pass through is a waist-shaped hole. The first auxiliary wheel 3106 is threadedly connected to the corresponding auxiliary wheel adjusting member 3109 at its position through the first auxiliary wheel fixing stud 3112, and the second auxiliary wheel 3107 is threadedly connected to the corresponding auxiliary wheel adjusting member 3109 at its position through the second auxiliary wheel fixing stud 3111.

[0039] As a preferred solution, a first auxiliary wheel position adjustment fastener 3102 for adjusting the up and down position of the first auxiliary wheel 3106 is provided below the first auxiliary wheel 3106, and a second auxiliary wheel position adjustment fastener 3103 for adjusting the front and rear position of the second auxiliary wheel 3107 is provided on the right side, and the ends of the first auxiliary wheel position adjustment fastener 3102 and the second auxiliary wheel position adjustment fastener 3103 both abut against the auxiliary wheel adjustment member 3109 at their positions. In this embodiment, the first auxiliary wheel position adjustment fastener 3102 and the second auxiliary wheel position adjustment fastener 3103 are screws and nuts, and the screws are threadedly connected with the nuts after passing through the auxiliary wheel mounting bracket 3101. The position adjustment method of the first auxiliary wheel and the second auxiliary wheel is the same. For example, when the position of the first auxiliary wheel needs to be adjusted upward, the screw is screwed upward so that the screw moves upward against the auxiliary wheel adjustment member, thereby causing the auxiliary wheel adjustment member to move upward with the first auxiliary wheel.

[0040] As a preferred solution, one side of the first auxiliary wheel 3106 and the second auxiliary wheel 3107 are both provided with auxiliary wheel chip removing springs 3105 for scraping off the debris left on the auxiliary wheels when the plate passes through the auxiliary wheels.

[0043] The edge banding machine is provided with an upper and lower set of arc scraper units, each of which has a profiling wheel. When the plate moves along the traveling direction, the profiling wheel of the edge banding machine follows the edge shape of the plate to grind and trim it. The wheel surface of the second auxiliary supporting wheel 3107 of the upper supporting wheel module 32 contacts the edge position of the upper end face of the plate, and the wheel surface of the first auxiliary supporting wheel 3106 contacts the side face of the plate. The second auxiliary supporting wheel 3107 of the lower supporting wheel module 31 contacts the side face of the plate, and the wheel surface of the first auxiliary supporting wheel 3106 contacts the edge position of the lower end face of the plate. The second auxiliary supporting wheel 3107 of the upper supporting wheel module 32 and the first auxiliary supporting wheel 3106 of the lower supporting wheel module 31 press the plate up and down. As the plate moves, when At the moment when the profiling wheel of the upper arc scraper unit loses contact with the plate, since the second auxiliary supporting wheel 3107 of the upper supporting wheel module 32 at this group of positions is still in contact with the plate, the plate still supports this group of arc scraper units, and therefore, the profiling wheel and its arc scraper unit at this group of positions will not sink instantaneously; then the plate continues to move forward along the traveling direction, and at the moment when the profiling wheel of the lower arc scraper unit loses contact with the plate, the wheel surface of the first auxiliary supporting wheel 3106 of the lower supporting wheel module 31 is still in contact with the edge position of the lower end surface of the plate, which will support the plate from below, and therefore, the profiling wheel and its arc scraper unit at this group of positions will not sink instantaneously.

[0044] It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
