DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than 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.

[0026] See also Figure 1-6 The utility model provides a technical solution for a scraper device of a plate edge banding machine: a scraper device of a plate edge banding machine, comprising an upper scraper mechanism 7 and a lower scraper mechanism 8 symmetrically mounted on the edge banding machine, and the upper scraper mechanism 7 and the lower scraper mechanism 8 have the same structural principle;

[0027] The upper scraper mechanism 7 includes a mounting plate 1 installed on the edge banding machine and a fine-tuning spring assembly 21 and a connecting shaft 22 connected to one side of the mounting plate 1. The fine-tuning spring assembly 21 and one end of the connecting shaft 22 are commonly connected to a fixed seat 2. One end of the connecting shaft 22 passes through the fixed seat 2 and is rotatably connected thereto. A torsion spring 23 is installed on one side of the fixed seat 2 corresponding to one end of the connecting shaft 22. One end of the torsion spring 23 is fixed to the side of the fixed seat 2, and the other end of the torsion spring 23 is fixed to one end of the connecting shaft 22. The fine-tuning spring assembly 21 includes a telescopic rod and a spring. The telescopic end of the telescopic rod is rotatably connected to the top end of the front side of the fixed seat 2, and the other end of the telescopic rod is fixed. On the mounting plate 1, the spring is sleeved on the telescopic rod, and the front-rear distance of the scraper mechanism can be fine-tuned by the cooperation of the fine-tuning spring assembly 21 and the connecting shaft rod 22. During the scraping operation, when the scraper mechanism (i.e., the upper scraper mechanism 7 and the lower scraper mechanism 8) scrapes the sheet strips of different thicknesses, it can be fine-tuned upward by the force, so that the telescopic rod of the fine-tuning spring assembly 21 retracts and compresses the spring. At the same time, the rotational torsion force of the connecting shaft rod 22 and the torsion spring 23 will react on the scraper mechanism, providing a stable pressure between the scraper mechanism and the sheet strip, facilitating the control of the distance between the sheet strip and the scraper mechanism, so that the scraper 33 is stably fed and the scraping wire has good stability.

[0028] A rotatable vertical pressure wheel 6 is installed on the front side of the fixed seat 2, a vertical adjustment mechanism is installed on the upper end of the other side of the fixed seat 2, and the bottom end of the vertical adjustment mechanism is connected to a scraper 33 located on the rear side of the vertical pressure wheel 6. The vertical adjustment mechanism includes a vertical adjustment seat 3 installed on the top of the side of the fixed seat 2, a vertical adjustment screw 31 is threadedly connected on the vertical adjustment seat 3, and the bottom end of the vertical adjustment screw 31 is rotatably connected to a vertical slide seat 32. The bottom end of the vertical adjustment screw 31 is sleeved with a spring. A sliding groove is provided on the side corresponding to the vertical slide 32, and the vertical slide 32 is slidably connected in the sliding groove. The scraper 33 is fixed to the front side of the bottom end of the vertical slide 32 in a detachable manner by bolts. When it is suitable for scraping strips of plates with different thicknesses, the vertical adjustment screw 31 can be turned according to the thickness of the plate to make its bottom end drive the vertical slide 32 to slide upward or downward in the sliding groove on the side of the fixed seat 2, thereby driving the scraper 33 to move up or down, so as to adapt to the scraping operation of strips of plates with different thicknesses.

[0029] The bottom end of the other side of the fixed seat 2 is provided with a transverse adjustment mechanism, and the front end of the transverse adjustment mechanism is provided with a transverse pressure wheel 53 located below the scraper 33. The transverse adjustment mechanism includes a transverse adjustment seat 5 installed at the bottom end of the side of the fixed seat 2, and a transverse adjustment screw 51 is threadedly penetrated on the transverse adjustment seat 5, and one end of the transverse adjustment screw 51 is rotatably connected to a transverse slide 52. A slide groove is also provided at the bottom end of the side of the fixed seat 2 corresponding to the transverse slide 52, and the transverse slide 52 is slidably connected in the slide groove, and the transverse pressure wheel 53 is detachably mounted on the bottom end of the front end of the transverse slide 52 by a bolt. By screwing the transverse adjustment screw 51, the transverse slide 52 is threadedly rotated on the transverse adjustment seat 5, thereby pushing the transverse slide 52 to drive the transverse pressure wheel 53 to move forward and backward along the slide groove, thereby adjusting the spacing between the transverse pressure wheel 53 and the side strip of the plate, ensuring that the transverse pressure wheel 53 is squeezed on the side strip of the plate to achieve squeezing, which is convenient for the scraping operation of the scraper 33.

[0030] A mounting frame 41 is also installed on the side of the fixed seat 2, and a dust hood 4 is fixed on the mounting frame 41 at an angle. The inclined end of the dust hood 4 corresponds to the scraper 33. One end of the dust hood 4 is connected to an external dust suction device. The dust hood 4 cooperates with the operation of the dust suction device to remove waste debris generated by the scraper 33 during scraping, thereby improving the scraping effect of the plate strip.

[0031] The working principle of the utility model is as follows: before use, according to the thickness of the plate, the horizontal pressing wheel 53 is adjusted to the side strip of the plate by using the horizontal adjustment mechanism, so that the horizontal pressing wheel 53 can squeeze and limit the plate strip, which is convenient for squeezing the side of the plate strip when scraping the plate strip, and using the vertical pressing wheel 6 to roll the upper surface of the plate to limit the size of the scraper 33;

[0032] In addition, the height position of the scraper 33 can be adjusted by using the vertical adjustment mechanism according to the thickness of the plate, so that the scraper 33 is adapted to the plate strip, thereby improving the scraping effect of the plate strip;

[0033] During the scraping operation, the front and rear distance of the scraper mechanism can be fine-tuned by utilizing the cooperation of the fine-tuning spring assembly 21 and the connecting shaft rod 22, so that there is a stable pressure between the scraper mechanism and the sheet strip, which facilitates the control of the distance between the sheet strip and the scraper mechanism, and makes the scraper 33 bite stably and the scraping wire has good stability.

[0034] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
