Description

Technical Field

[0001] This utility model relates to the field of edge banding machines for sheet metal, and specifically to a polishing device for an edge banding machine. Background Technology

[0002] Currently, edge banding machines are used for side edge banding, trimming, and polishing of boards. During this process, the boards are conveyed longitudinally via a chain conveyor. The edge banding machine also has a pressure beam with a pressure roller rotatably connected to its bottom. The pressure roller presses the board against the chain conveyor to prevent easy displacement. In the polishing process, two polishing wheels are used to polish the upper and lower edges of the edge banding on the side of the board. The upper polishing wheel is mounted on the output shaft of the upper polishing motor. Currently, the upper polishing motor is set on the pressure beam. Therefore, the vibration generated by the operation of the upper polishing motor is transmitted to the pressure beam. Since the pressure beam is set up to slide up and down, there are inevitably gaps in the sliding structure, meaning that the rigidity of the pressure beam is relatively low. This leads to increased vibration, which affects the working stability of the upper polishing wheel and is not conducive to improving the polishing effect. Moreover, the vibration of the pressure beam also affects the stability of the pressure roller holding the board, which is not conducive to the stable conveying of the board. Therefore, the existing polishing device needs to be improved. Summary of the Invention

DETAILED DESCRIPTION

[0016] The utility model will be further described below in combination with the drawings.

[0017] The polishing device of the edge banding machine, as shown in Figures 1 to 3 , comprises an upper polishing assembly 1 and a lower polishing assembly 2, and further comprises a support 3, a lower polishing vertical position adjusting screw 4, an upper polishing vertical position adjusting screw 6, and a screw rod supporting corner seat 8 for being installed on the front side of the pressing beam 99. The support 3 comprises a slide column 32 and a bottom plate 31 for being installed on the bed body 97 of the edge banding machine. The lower end of the slide column 32 is fixedly connected to the bottom plate 31. For example, the lower end surface of the slide column 32 is formed with a screw hole. A screw is used to pass through the bottom plate 31 upwards and is connected to the screw hole. The bottom plate 31 is installed on the bed body 97 through corresponding screws. A support is installed on the bed body 97. The pressing beam 99 is arranged on the support in an up-and-down sliding mode (it should be noted that the support is not shown in each drawing). Figure 1 and Figure 2 As shown in the drawings, the upper end of the slide column 32 is provided with a top plate 33. The top plate 33 can be installed on the upper end of the slide column 32 through corresponding screws. The upper polishing assembly 1 comprises an upper polishing motor 11 and an upper lifting seat 12. The output rotating shaft of the upper polishing motor 11 is provided with an upper polishing wheel 111. The upper polishing motor 11 is arranged on the upper lifting seat 12. The upper lifting seat 12 is connected to the slide column 32 in an up-and-down sliding mode. The lower polishing assembly 2 comprises a lower polishing motor 21 and a lower lifting seat 22. The output rotating shaft of the lower polishing motor 21 is provided with a lower polishing wheel 211. The lower polishing motor 21 is arranged on the lower lifting seat 22. The lower lifting seat 22 is connected to the slide column 32 in an up-and-down sliding mode. The upper end of the upper polishing vertical position adjusting screw 6 is rotationally connected to the screw rod supporting corner seat 8. Specifically, the screw rod supporting corner seat 8 comprises a vertical plate and a horizontal plate. The upper end of the vertical plate is welded to the rear end of the horizontal plate. Figure 3As shown, the vertical plate is attached to the front side of the pressure beam 97. The vertical plate is connected to the pressure beam 97 by corresponding screws. The upper end of the upper polishing vertical adjustment screw 6 is adapted to pass through the horizontal plate. The upper part of the upper polishing vertical adjustment screw 6 has a shoulder, which is attached to the lower side of the horizontal plate. The upper polishing vertical adjustment screw 6 is screwed with two hexagonal nuts, which are located on the upper side of the horizontal plate, thereby axially positioning the upper polishing vertical adjustment screw 6 and allowing it to rotate. The lower end of the upper polishing vertical adjustment screw 6 is screwed to the upper lifting seat 12. Specifically, the rear end of the upper lifting seat 12 has a threaded hole, and the lower end of the upper polishing vertical adjustment screw 6 is connected to the threaded hole. Figure 1 and Figure 3 As shown, the lower polishing vertical adjustment screw 4 is rotatably connected to the top plate 33, and the lower end of the lower polishing vertical adjustment screw 4 is screwed to the lower lifting seat 22.

[0018] like Figure 3 As shown, the upper polishing wheel 111 contacts the upper edge of the plate 98, and the lower polishing wheel 211 contacts the lower edge of the plate 98. The upper polishing motor 11 drives the upper polishing wheel 111 to rotate, and the lower polishing motor 21 drives the lower polishing wheel 211 to rotate. Since the bracket 3 is installed on the bed 97, the bracket 3 has high rigidity, making it difficult for the upper polishing motor 11 and the lower polishing motor 21 to vibrate. The upper polishing vertical adjustment screw 6 plays the role of suspending the upper polishing assembly 1, and the lower polishing vertical adjustment screw 4 plays the role of suspending the upper polishing assembly 2. The vibration generated by the upper polishing motor 11 in the vertical direction will be partially transmitted to the pressure beam 99 through the upper polishing vertical adjustment screw 6. However, the vibration generated by the upper polishing motor 11 in the horizontal and vertical directions will be directly supported by the bracket 3, avoiding the aggravation of the vibration of the upper polishing motor 11. That is to say, the upper polishing motor 11 is supported by high rigidity, which reduces the vibration and is conducive to improving the polishing effect of the polishing device. Moreover, the vibration that can be transmitted to the pressure beam 99 is also greatly reduced, avoiding significant impact on the conveying of the plate 98. When the thickness of the plate 98 changes, rotating the upper polishing vertical adjustment screw 6 can move the upper polishing component 1 up and down for adjustment; rotating the lower polishing vertical adjustment screw 4 can move the lower lifting seat 22 up for adjustment. Since the lower polishing motor 21 is located on the lower lifting seat 22, the lower polishing wheel 211 can be adjusted upward to increase the polishing intensity of the lower polishing wheel 211 on the plate 98. Similarly, the polishing intensity of the upper polishing wheel 111 on the plate 98 can also be adjusted by rotating the upper polishing vertical adjustment screw 6.

[0019] Furthermore, such as Figure 1As shown, the number of slide columns 32 is set to two, the lower polishing vertical positioning screw 4 is arranged in the middle of the two slide columns 32, the upper lifting seat 12 is formed with a through hole 1201, the lower polishing vertical positioning screw 4 passes through the through hole 1201, specifically, a linear bearing is installed in the upper lifting seat 12, the slide column 32 is adapted to pass through the corresponding linear bearing, so that the bracket 3 can move up and down on the upper lifting seat 12 with high rigidity linear guidance. Since the through hole 1201 is arranged to avoid the lower polishing vertical positioning screw 4, the lower polishing vertical positioning screw 4 can be arranged in the middle of the two slide columns 32, which can facilitate the compact structure of the polishing device.

[0020] Further, the upper polishing vertical positioning screw 6 is arranged at the rear side of the slide column 32, so that, as shown, Figure 3 the upper polishing vertical positioning screw 6 can be arranged rearward, and the upper polishing vertical positioning screw 6 can be closer to the press beam 99, so that the above-mentioned forward extension range of the horizontal plate of the screw support angle seat 8 can be reduced, and the above-mentioned layout setting is more reasonable. When the press beam 99 moves up and down, the press beam 99 drives the screw support angle seat 8 to move up and down, and the screw support angle seat 8 drives the upper polishing assembly 1 to move up and down through the upper polishing vertical positioning screw 6. As shown, Figure 1 the upper end of the upper polishing vertical positioning screw 6 is installed with an upper polishing positioning hand wheel 7, and the upper end of the lower polishing vertical positioning screw 4 is installed with a lower polishing positioning hand wheel 5.

[0021] Further, as shown, Figure 2 the upper polishing assembly 1 comprises a transverse positioning seat 13, the transverse positioning seat 13 is arranged on the upper lifting seat 12, and the upper polishing motor 11 is installed on the transverse positioning seat 13, in other words, the transverse positioning seat 13 can transversely position the upper polishing motor 11 (i.e., position in the direction perpendicular to the conveying direction of the plate 98), as shown, Figure 3 the plate 98 is conveyed in the left-right direction, so that the "transverse direction" is the front-rear direction, and the transverse positioning seat 13 can move forward and backward relative to the upper lifting seat 12. As shown, Figure 3 when the axial partial position of the upper polishing wheel 111 is obviously worn (specifically, the front part of the upper polishing wheel 111 is worn), the transverse positioning seat 13 can be positioned to move the upper polishing wheel 111 backward, so that the non-worn part of the upper polishing wheel 111 can contact the upper edge of the plate 98, and the upper polishing wheel 111 can be fully utilized, which is conducive to reducing production cost. The positioning mode of the transverse positioning seat 13 can be manual or electric.

[0022] Further, as shown, Figure 4As shown, the transverse adjusting seat 13 is formed with an adjusting seat bottom surface 131, an adjusting seat lower waist surface 132, an adjusting seat upper waist surface 133 and an adjusting seat top surface 134, the adjusting seat lower waist surface 132 and the adjusting seat upper waist surface 133 form an acute angle with the adjusting seat bottom surface 131, so that the cross section of the transverse adjusting seat 13 is trapezoidal, more preferably, the cross section of the transverse adjusting seat 13 is isosceles trapezoidal, the adjusting seat bottom surface 131 is a vertical surface, so that the adjusting seat top surface 134 is parallel to the adjusting seat bottom surface 131, the adjusting seat bottom surface 131 abuts against the right surface of the upper lifting seat 12, the upper polishing motor 11 is installed on the adjusting seat top surface 134 through corresponding screws, the upper lifting seat 12 is installed with a guide block 121, the guide block 121 is adapted to abut against the adjusting seat lower waist surface 132, in other words, the upper surface of the guide block 121 is obliquely arranged relative to the right surface of the upper lifting seat 12, and the upper surface of the guide block 121 is parallel to the adjusting seat lower waist surface 132, the upper lifting seat 12 is provided with a conical pressure roller 122, the conical pressure roller 122 is formed with a tapered roller center hole 1221, a fixing screw is installed in the tapered roller center hole 1221, the fixing screw is screwed with the upper lifting seat 12, the conical pressure roller 122 is formed with a conical surface, the conical surface is adapted to abut against the adjusting seat upper waist surface 133, specifically, the generatrix of the conical surface is in parallel contact with the adjusting seat upper waist surface 133, the conical pressure roller 122 is arranged in the front-rear direction, and the number of the corresponding conical pressure rollers 122 of the upper lifting seat 12 can be two. When the fixing screw is tightened, the head of the fixing screw pushes the conical pressure roller 122 to the left, so that the conical surface presses the upper part of the transverse adjusting seat 13 against the right surface of the upper lifting seat 12, and the conical surface also generates a downward component force on the transverse adjusting seat 13, so that the adjusting seat lower waist surface 132 presses against the guide block 121, so that the transverse adjusting seat 13 is relatively fixed with the upper lifting seat 12 through the static friction between the transverse adjusting seat 13 and the upper lifting seat 12 and the static friction between the transverse adjusting seat 13 and the guide block 121. When it is necessary to adjust the transverse adjusting seat 13 in the front-rear direction, the fixing screw is loosened, the conical pressure roller 122 is loosened from the adjusting seat upper waist surface 133, and the upper polishing motor 11 is moved forward and backward by hand, so as to drive the transverse adjusting seat 13 to move forward and backward, during which the lower part of the transverse adjusting seat 13 slides forward and backward between the upper surface of the guide block 121 and the right surface of the upper lifting seat 12, and the conical pressure roller 122 can also guide the transverse adjusting seat 13 to move forward and backward; when the adjustment is completed, the fixing screw is tightened again.

[0023] As shown in Figure 1 and Figure 2 , the lower polishing assembly 2 has the same structure as the upper polishing assembly 1.
