[0025] Beneficial effects of the present invention.

[0026] 1. The four-sided sanding system of the present invention ingeniously adopts mutually perpendicular transversely arranged sanding devices and vertically arranged sanding devices and their pushing mechanisms, so that the vertical and mutually perpendicular sides of the drawer wooden box are sanded in sequence, which saves time, is convenient and trouble-free, and greatly improves the sanding efficiency.

[0027] 2. The sanding device of the present invention adopts a lifting sanding mechanism, so that during the transmission process, the drawer wooden box is not only sanded in the left and right directions by the sanding belt in the lifting sanding mechanism, but also sanded in the up and down directions by the lifting mechanism in the lifting sanding mechanism.

[0028] 3. The lifting action of the lifting sanding mechanism of the sanding device of the present invention is realized by a motor, a reducer, an eccentric wheel, and a rod end bearing, so that the lifting action of the lifting sanding mechanism is more stable and not easy to shake.

[0029] 4. The sanding device of the four-sided sanding system of the present invention can adapt to drawer wooden boxes of different widths. The active chain shaft and the driven chain shaft in the synchronous chain transmission assembly adopt polygonal shafts, and the position of the sprocket on the polygonal shaft can be flexibly moved, so as to adjust the spacing between the two synchronous chain transmission assemblies to adapt to drawer wooden boxes of different widths. Then, the spacing between the lifting sanding mechanisms on both sides of the synchronous chain transmission assembly is adjusted by the spacing adjustment mechanism, and the spacing between the movable workbench and the fixed workbench is also adjusted accordingly.

[0030] 5. The center distance adjustment mechanism of the present invention adopts the rotation of the ball screw in the ball screw pair to drive the linear movement of the nut, thereby driving the slide plate 1 to slide on the slide rod 2 through the slide sleeve 2 to achieve the adjustment of the distance between the lifting sanding mechanism. At the same time, the slide plate 1 drives the movable workbench to slide on the slide rod 3 through the slide sleeve 3 to achieve the adjustment of the distance between the workbench. The structure is simple, and the adjustment is labor-saving and convenient.

[0031] 6. After the center distance adjustment mechanism of the present invention is adjusted, it can be locked and fixed by the locking mechanism, so that the structure is more stable during operation. The locking mechanism uses the adjustment of the threaded shaft to achieve the biting, locking and loosening of the opening groove in the U-shaped block and the limit long block. Since the U-shaped block and the limit long block are locked on three surfaces, the locking is more firm and more stable.

[0032] 7. The driven roller and the upper bottom plate in the sanding mechanism of the present invention are movably and adjustablely connected. The outer side of the driven roller can be slightly tilted by adjusting bolts and springs, so that the sanding belt is not easy to fall off from the upper part during operation. A boss larger than the diameter of the driven roller is provided at the lower part of the driven roller, so that the sanding belt is not easy to fall off from the lower part during operation. At the same time, a certain adjustment margin is reserved for the middle distance between the driven roller and the active roller, which is more convenient when installing and removing the sanding belt, and the sanding belt will not be damaged due to the need to pull the sanding belt with great force.

[0033] 8. The four-sided sanding system of the present invention has a simple structure and ingenious design. It adopts two sanding devices arranged perpendicular to each other to achieve sanding on the four sides of the drawer wooden box, and adopts a lifting sanding mechanism to achieve simultaneous sanding in the up, down, left and right directions.

[0075] The second waist-shaped hole 7.2 is provided in the induction component 7 to facilitate the adjustment of the distance between the induction sensor 7.4 and the drawer wooden boxes 9 of different widths. The provision of the perforation 7.3 facilitates the installation of the induction sensor 7.2 in a more beautiful manner.

[0076] The pushing mechanism 8 includes a vertical support rod 8.1 fixed to one side of the base frame 1, a transverse support rod 8.2 is laterally fixed to the upper end of the vertical support rod 8.1, a support block 8.3 is fixed to the outer end of the transverse support rod 8.2, a transverse cylinder 8.4 is installed on the vertical support rod 8.1, the upper end of the transverse cylinder 8.4 is fixed to the support block 8.3, and a vertical cylinder 8.5 is vertically fixed to the rod end of the transverse cylinder 8.4.

[0077] The setting of the pushing mechanism 8 facilitates the drawer wooden box to be pulled from the tail of the horizontally arranged sanding device conveying mechanism 2 to the vertically arranged sanding device conveying mechanism 2, playing a transmission role between the two mutually perpendicular conveying mechanisms.

[0078] The working principle and process of the present invention.

[0079] like Figure 1-12 As shown, the main working process of this four-sided sanding system.

[0080] The drawer wooden box is placed on the front of the push block 2.5 on the chain 2.4 of the conveying mechanism 2 of the horizontally arranged sanding device. The drawer wooden box 9 is polished on both sides of the drawer wooden box 9 in turn through the lifting sanding mechanism 5 on both sides during the movement of the conveying mechanism 2. When the drawer wooden box 9 moves to the tail of the conveying mechanism 2, the sensing component 7 senses that the drawer wooden box 9 is being conveyed. The original horizontal cylinder 8.4 of the pushing mechanism 8 is in an extended state and is located above the drawer wooden box 9. The control mechanism starts the vertical cylinder 8.5 of the pushing mechanism 8 to extend downward and contact the drawer wooden box 9, and then the horizontal cylinder 8.4 contracts and pulls it toward the vertically arranged sanding device. It is pulled to the front of the push block 2.5 of the chain 2.4 of the conveying mechanism 2 in the vertically arranged sanding device. At this time, the other two sides of the drawer wooden box 9 are polished in turn with the lifting sanding mechanism during the conveying process of the conveying mechanism 2. Finally, the four sides of the drawer wooden box 9 are polished in the front, back, left and right directions during the movement.

[0081] Specific working process of sanding device.

[0082] The drawer wooden box 9 is placed on the chain 2.4 of the synchronous chain transmission assembly in the conveying mechanism 2. The rear of the drawer wooden box 9 is limited by the push block 2.5 on the chain 2.4. The driving mechanism is started. The driving motor drives the driving reducer through the driving belt transmission assembly. The driving reducer drives the synchronous chain transmission assembly to operate through the chain transmission assembly. The chain 2.4 operates through the push blocks 2.5 evenly spaced on the chain 2.4 to drive the drawer wooden box 9 to move forward and encounter the fixed workbench 10 / movable workbench 11 on one side. The motor 1 5.2 in the sanding mechanism 5 drives the eccentric wheel 5.4 through the reducer 1 5.3, and the eccentric wheel 5.4 drives the slide plate 2 5.6 to move up and down through the rod end bearing 5.5, so that the sliding sleeve 2 5.7 on the slide plate 2 5.6 slides up and down on the sliding rod 2 5.8, thereby driving the entire sanding mechanism of the upper bottom plate 5.10 to move up and down, and at the same time, the sanding belt on the sanding mechanism 5 also rotates left and right, so that the side of the drawer wooden box can be sanded up and down and left and right during the conveying process of the conveying mechanism.

[0083] The spacing adjustment process of the sanding device.

[0084] When it is necessary to polish drawer wooden boxes of different widths, first adjust the spacing between the two interval synchronous sprocket drive components, and adjust the spacing by moving the sprocket 2.7 in the synchronous belt drive component installed on the side of the movable workbench 11 on the polygonal axis, and then move and adjust the lifting sanding mechanism 5 on the side of the movable workbench 11 through the spacing adjustment mechanism 3. The specific adjustment process of the spacing adjustment mechanism is that the ball screw in the ball screw pair 3.5 rotates by adjusting the hand wheel 3.6, thereby driving the nut in the ball screw pair 3.5 to move, and the movement of the nut drives the slide plate 1 3.4 to move, and the sliding sleeve 2 3.3 at the bottom of the slide plate 1 3.4 moves on the sliding rod 2 3.2, and the movement of the slide plate 1 3.4 drives the lifting sanding mechanism 5 and the movable workbench 11 thereon to move, thereby achieving the spacing between the two lifting sanding mechanisms 5 and the spacing between the movable workbench 11 and the fixed workbench 10, so that the spacing between the lifting sanding mechanisms 5 on both sides and the spacing between the workbench are adapted to the spacing between the adjusted two synchronous chain drive components.

[0085] In the spacing adjustment state, as the slide plate 3.4 moves, the shaft moves in the waist groove 4.6, and the opening groove of the U-shaped block 4.5 and the limiting long block 4.2 are in a loose state. When the width is adjusted, it is locked by the locking mechanism 4. The threaded shaft 4.4 is turned by the locking hand wheel 4.7 to drive the U-shaped block 4.5 at the bottom of the threaded shaft 4.4 to move upward until the opening groove of the U-shaped block 4.5 is clamped with the limiting long block 4.2, thereby locking the slide plate 3.4 so that the slide plate 3.4 is fixed to the base frame 1 through the limiting long block 4.2.

[0086] The special structural setting function of the driven roller in the sanding mechanism.

[0087] The lower part of the driven roller 5.12 is provided with a boss 5.20 which is larger than the diameter of the driven roller 5.12. During the operation of the sanding mechanism, the sanding belt 5.13 is prevented from falling off from the lower part of the driven roller 5.12. In order to prevent the sanding belt 5.13 from falling off easily, a fixed column 5.15 is fixed to the middle part of the bottom of the driven roller 5.12. The upper part of the fixed column 5.16 passes through the movable plate 5.17 and is movably connected to the movable plate 5.17. The lower part of the fixed column 5.16 is fixed in the fixed seat 5.15. The movable plate 5.17 is close to the active roller 5.12. .11 is provided with an adjusting screw assembly 5.18 passing through the movable plate 5.17, and a spring 5.19 is provided between the other side of the movable plate 5.17 and the bottom plate 5.1. Due to the driven roller 5.12, during the operation of the sand belt 5.13, the driven roller 5.12 can adjust the height of the inner and outer sides of the driven roller 5.12 by adjusting the bolt 5.18 and the spring 5.19, and adjust the outer side of the driven roller 5.12 to be slightly higher, so that the upper part of the driven roller 5.12 will not fall off during the operation of the sand belt 5.13. Due to the setting of the adjusting bolt on the outer side of the driven roller 5.12 and the spring 5.19 on the inner side, the center distance between the active roller 5.11 and the driven roller 5.12 has a certain adjustment margin, which makes it more convenient to install the sand belt 5.13, and the sand belt 5.13 is not easily damaged by pulling.

[0088] This four-sided sanding system cleverly adopts mutually perpendicular transversely arranged sanding devices and vertically arranged sanding devices and their pushing mechanisms 8, so that the vertical and mutually perpendicular side surfaces of the drawer wooden box 9 are sanded in sequence, saving time, convenience and trouble, and greatly improving the sanding efficiency.

[0089] The sanding device in this four-sided sanding system adopts a lifting sanding mechanism, so that during the transmission process, the drawer wooden box 9 is not only sanded in the left and right directions by the sanding belt 5.13 in the lifting sanding mechanism, but also sanded in the up and down directions by the lifting mechanism in the lifting sanding mechanism. It is sanded in two dimensions at the same time, thereby improving the sanding efficiency and quality.

[0090] The lifting action of the lifting sanding mechanism 5 in the sanding device is realized by a motor 5.2, a reducer 5.3, an eccentric wheel 5.4, and a rod end bearing 5.5, so that the lifting action of the lifting sanding mechanism 5 is more stable and not easy to shake.

[0091] The sanding device in this four-sided sanding system can adapt to drawer wooden boxes 9 of different widths. The active chain shaft 2.1 and the driven chain shaft 2.2 in the synchronous chain transmission assembly adopt polygonal shafts, and the position of the sprocket 2.7 on the polygonal shaft can be flexibly moved, so as to adjust the spacing between the two synchronous chain transmission assemblies to adapt to drawer wooden boxes 9 of different widths. Then, the spacing between the lifting sanding mechanism 5 on both sides of the synchronous chain transmission assembly is adjusted by the spacing adjustment mechanism 3, and the spacing between the movable workbench 11 and the fixed workbench 10 is also adjusted accordingly. One side of the bottom frame 1 is fixedly connected to the fixed workbench 10, and the other side is movably connected to the movable workbench 11, so as to facilitate the adjustment of the spacing between the movable workbench 11 and the fixed workbench 10.

[0092] The spacing adjustment mechanism 3 uses the rotation of the ball screw in the ball screw pair 3.5 to drive the linear movement of the nut, thereby driving the slide plate 1 3.4 to slide on the slide rod 2 3.2 through the slide sleeve 2 3.3 to achieve the adjustment of the spacing of the lifting sanding mechanism 5. At the same time, the slide plate 1 3.4 drives the movable workbench 11 to slide on the slide rod 3 13 through the slide sleeve 3 12 to achieve the adjustment of the workbench spacing. The structure is simple, and the adjustment is labor-saving and convenient.

[0093] In this four-sided sanding system, the sanding device can be locked and fixed by the locking mechanism 4 after the spacing adjustment mechanism 3 is adjusted, so that the structure is more stable during operation. The locking mechanism 4 uses the adjustment of the threaded shaft 4.4 to achieve the biting, locking and loosening of the opening groove in the U-shaped block 4.5 and the limit long block 4.2. Since the U-shaped block 4.5 and the limit long block 4.2 are locked on three sides, the locking is more firm and more stable.

[0094] The driven roller 5.12 in the sanding mechanism is movably and adjustablely connected to the upper base plate 5.10. The outer side of the driven roller 5.12 can be slightly tilted by adjusting the bolt 5.18 and the spring 5.19, so that the sanding belt 5.13 is not easy to fall off from the upper part during operation. The lower part of the driven roller 5.12 is provided with a boss 5.20 larger than the diameter of the driven roller 5.12, so that the sanding belt 5.13 is not easy to fall off from the lower part during operation. At the same time, a certain adjustment margin is reserved for the middle distance between the driven roller 5.12 and the active roller 5.11, which is more convenient when installing and removing the sanding belt 5.13, and the sanding belt 5.13 will not be damaged due to the need to pull the sanding belt 5.13 with great force.

[0095] This four-sided sanding system has a simple structure and ingenious design. It adopts two sanding devices arranged perpendicular to each other to achieve sanding on the four sides of the drawer wooden box, and adopts a lifting sanding mechanism 5 to achieve simultaneous sanding in the upper, lower, left and right directions. It has high sanding efficiency and good quality. It can be used for sanding drawer wooden boxes 9 of different widths, has a wide range of applications, and is highly practical. The sanding belt 5.13 is not easy to fall off, and is easy to install and disassemble.

[0096] Although the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
