DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-3 The utility model provides a technical solution for an adaptive high-precision trimming device for a plate edge banding machine: an adaptive high-precision trimming device for a plate edge banding machine, comprising an upper finishing mechanism 1 and a lower finishing mechanism 2 installed on the plate edge banding machine, the upper finishing mechanism 1 and the lower finishing mechanism 2 having the same structure and being symmetrically arranged, the upper finishing mechanism 1 can be used to cut excess strips on the upper side of the plate after edge banding, and the lower finishing mechanism 2 can be used to cut excess strips on the lower side of the plate after edge banding, and the structures, working principles and adjustment methods of the upper finishing mechanism 1 and the lower finishing mechanism 2 are consistent, and when working, the excess strips on the side of the plate can be cut synchronously, and the upper finishing mechanism 1 and the lower finishing mechanism 2 are correspondingly installed on the upper and lower vertical plates of the plate edge banding machine, and the resonance effects of the upper and lower finishing are offset each other, thereby reducing vibration and achieving high trimming accuracy;

[0025] like Figure 4-6 As shown, the upper finishing mechanism 1 includes a mounting plate 21 mounted on the vertical plate of the plate edge banding machine, a spring buffer 22 is fixedly mounted on the upper end of the mounting plate 21, the spring buffer 22 adopts the existing conventional retractable and reset spring buffer, and a fine-tuning rotating rod 23 is fixedly connected to the rear side of the lower end of the mounting plate 21, the spring buffer 22 is inclined and its inclined end is connected to a connecting seat 24, a torsion spring is installed at the rear end of the connecting seat 24, the other end of the fine-tuning rotating rod 23 passes through the connecting seat 24 and is connected to one end of the torsion spring, and the fine-tuning rotating rod 23 is fixedly connected to the rear side of the lower end of the mounting plate 21. 23 is rotatably connected to the connecting seat 24. When fine-tuning plates of different thicknesses, the entire trimming device acts on the plate, and can be fine-tuned upward as a whole under the influence of the reaction force. When the entire device is fine-tuned upward, it will move upward through the connecting seat 24. At this time, the force applied to the connecting seat 24 will cause the spring buffer 22 to retract. At the same time, the rotation of the connecting seat 24 will cause the torsion spring to generate torsion, thereby fine-tuning the entire device upward, and also generating a stable pressing plate pressure on the plate, ensuring that the fine-tuning of the fine-tuning mechanism is stable.

[0026] like Figure 4 and 7 As shown, a vertical adjustment mechanism and a lateral adjustment mechanism are provided on one side of the connecting seat 24. The connecting seat 24 is connected to the lateral adjustment mechanism through the vertical adjustment mechanism. The lower end of the lateral adjustment mechanism is connected to a driving motor 43. The output end of the driving motor 43 is connected to a finishing tool 44. The front side of the connecting seat 24 is connected to a positioning plate 5. The inner side of the positioning plate 5 is located on the outer side of the finishing tool 44 and is rotatably connected to a pressure roller 51. The pressure roller 51 can be used to apply a rolling force to the upper surface of the plate to avoid the plate from being offset during finishing and affecting the finishing accuracy.

[0027] like Figure 4-6 As shown, the vertical adjustment mechanism includes a vertical fixing plate 3 installed on the top of the side of the connecting seat 24 and a vertical slide rail 33 installed on the side of the connecting seat 24. The vertical slide rail 33 is slidably connected with a vertical slide seat 32. The surface of the vertical fixing plate 3 is threaded with a vertical adjustment screw 31. One end of the vertical adjustment screw 31 penetrates the vertical fixing plate 3 and is rotatably connected to the upper surface of the vertical slide seat 32. The vertical adjustment screw 31 is threadedly connected to the vertical fixing plate 3, and a knob is provided on the top of the vertical adjustment screw 31. By rotating The knob on the top of the vertical adjustment screw 31 causes it to rotate, and under the force of the thread, the vertical slide 32 will move linearly along the surface of the vertical adjustment screw 31, and limited by the vertical slide rail 33, the stability of the vertical slide 32 when adjusted up and down can be ensured. When the vertical slide 32 is adjusted up and down, the drive motor 43 and the finishing tool 44 can be driven by the lateral adjustment mechanism to perform fine adjustments up and down to adjust the vertical distance between the finishing tool 44 and the sheet strip, so as to be suitable for edge banding finishing operations of sheets of different thicknesses.

[0028] like Figure 1-3 As shown, the lateral adjustment mechanism includes a lateral slide rail 42 slidably connected to the vertical slide seat 32 and a lateral fixing plate 4 fixedly connected to one end of the lateral slide rail 42. A lateral adjustment screw 41 is provided through the middle of the side of the lateral fixing plate 4. The lateral adjustment screw 41 is rotatably connected to the lateral fixing plate 4, and one end of the lateral adjustment screw 41 is threaded into the vertical slide seat 32. The bottom ends of the lateral fixing plate 4 and the lateral slide rail 42 are fixedly connected to the top end of the driving motor 43. At one end of the lateral adjustment screw 41, a lateral adjustment screw 41 is also provided. A knob is provided, and by turning the knob, the rotation of the lateral adjustment screw 41 is controlled, so that it drives the lateral fixing plate 4 to be screwed into the vertical slide seat 32, that is, drives the lateral fixing plate 4 to approach the vertical slide seat 32. When the lateral fixing plate 4 moves, the driving motor 43 and the finishing tool 44 are synchronously driven to move in the same direction (that is, approach the edge banding strip of the plate), so as to adjust the lateral distance between the finishing tool 44 and the edge banding strip of the plate, ensuring that the finishing tool 44 is stable during finishing and has good finishing stability.

[0029] like Figure 6 and 7 As shown, a dust hood 6 is connected to one side of the upper surface of the vertical slide seat 32 by bolts, the bottom end of the dust hood 6 is open and is located directly above the finishing tool 44, a dust suction port is provided at the top of the dust hood 6, and the dust hood 6 is connected to an external dust suction device through the dust suction port, when the finishing tool 44 performs finishing processing on the edge banding strip of the plate, the waste chips generated can be sucked away by the dust hood 6 in cooperation with the external dust suction device, thereby avoiding the problem of finishing waste chips splashing everywhere, and an air blowing pipe is also installed on the connecting seat 24, which can directionally blow the waste chips generated by the finishing tool 44 during finishing, so that the finishing waste chips can be better sucked away.

[0030] The working principle of the utility model is as follows: during installation, the upper finishing mechanism 1 and the lower finishing mechanism 2 are symmetrically installed on the vertical plate of the plate edge banding machine by using the mounting plate 21, so that the finishing tools 44 of the upper finishing mechanism 1 and the lower finishing mechanism 2 correspond to the upper and lower ends of the side of the plate, so that the upper finishing mechanism 1 and the lower finishing mechanism 2 are convenient for cutting the redundant stickers at the upper and lower ends of the side of the plate, and the spring buffer 22 and the connecting seat 24 and the torsion spring and the fine-tuning rotating rod 23 are used to cooperate, so that the whole device can perform adaptive adjustment on the plate;

[0031] Before working, the vertical distance between the finishing tools 44 of the upper finishing mechanism 1 and the lower finishing mechanism 2 and the side strips of the plate can be adjusted by the vertical adjustment mechanism, and at the same time, the horizontal distance between the finishing tools 44 and the side strips of the plate can be adjusted by the horizontal adjustment mechanism, thereby adjusting the front-to-back and top-to-bottom distances of the finishing mechanisms, that is, the top-to-bottom and top-to-bottom distances of the two finishing tools 44 and the edge strips of the plate, and there is a stable pressure between the finishing mechanisms and the plate strips, which facilitates the control of the distance between the plate strips and the finishing tools 44, ensuring stable feeding during finishing and good finishing stability;

[0032] During fine trimming, by synchronously controlling the operation of the two driving motors 43, the two fine trimming tools 44 can simultaneously cut the excess strips on the side of the plate, which can improve the fine trimming efficiency after the plate is edge-sealed. Moreover, during fine trimming and cutting, the dust collecting hood 6 can be used to clean the fine trimming waste to ensure the cleanliness during fine trimming.

[0033] 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.
