Description

Technical Field

[0001] This invention relates to the field of drawer manufacturing technology, and in particular to a deburring device for the front panel of a drawer. Background Technology

[0002] As a tool storage solution, a toolbox serves to categorize and organize tools. Because tools are categorized and placed in a toolbox, users can quickly and accurately find the tools they need.

[0003] Toolboxes typically consist of a box body and drawers. The front panel of the drawers is formed by bending a long plate. The two sides of the long plate are bent to form the upper and lower edges of the front panel, respectively. In existing technology, the bent long plate is cut to a fixed length using specialized cutting equipment. The cut front panel ends will have protruding burrs. Depending on the processing requirements, the burrs at the rounded corners of the upper edge of the front panel need to be removed. Firstly, this area faces upwards, and workers may touch it during installation, potentially causing injury; secondly, decorative strips need to be installed along the upper edge of the front panel, and the burrs will interfere with the installation. Current deburring methods involve workers manually grinding away the burrs using a grinding wheel or sandpaper. However, due to varying operating techniques, the consistency of the ground areas along the upper edge of the front panel is inconsistent, and manual grinding is inefficient and no longer meets the needs of automated production. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a deburring device for the front panel of a drawer, which solves the problem of the difficulty in quickly removing burrs from the front panel of the drawer.

[0005] The technical solution of the present invention to achieve the above objectives is a deburring device for the front panel of a drawer, comprising: A sliding plate is used to support the entire device. The sliding plate can slide along the length of the workpiece to be processed, so as to adjust the grinding position according to the different lengths of the workpiece. A deburring mechanism is slidably disposed on the sliding plate and is capable of sliding along the width direction of the workpiece to be processed. The deburring mechanism includes an inclined and rotatable sandpaper belt. Mounting plate, which is liftably mounted above sliding plate, has a bracket above it, and has clearance holes on it to allow the sandpaper belt to extend to the top of the mounting plate for sanding the part to be sanded on one side of the workpiece. The extension direction of the clearance holes is consistent with the moving direction of the deburring mechanism. A first positioning mechanism is adjustablely mounted on the bracket to adjust its position according to the width of the workpiece to be processed. The first positioning mechanism includes a first positioning block that can move up and down to position and press one side of the workpiece to be processed. The bottom of the first positioning block has a first positioning groove that matches the shape of one side of the workpiece to be processed. The second positioning mechanism is inclinedly disposed on one side of the mounting plate. The second positioning mechanism includes a second positioning block that can move obliquely to position and press the other side of the plate to be processed. The side of the second positioning block has a second positioning groove that matches the shape of the other side of the plate to be processed.

[0006] To facilitate the sliding of the sliding plate, a base plate is provided below the sliding plate. The base plate is fixedly installed on the base frame and a slide rail is provided on the base plate. The bottom of the sliding plate is horizontally slidably connected to the slide rail via a slider.

[0007] In order to control the movement of the sliding plate, the base plate is provided with an adjusting screw and a bearing seat. One end of the adjusting screw is rotatably connected to the bearing seat, and the other end is threadedly connected to the connecting block fixed at the bottom of the sliding plate.

[0008] As a preferred technical solution, the deburring mechanism further includes a sliding block, a support plate inclinedly disposed on the sliding block, a first synchronous wheel and a second synchronous wheel rotatably connected to the support plate, and a motor driving the first synchronous wheel to rotate. The two ends of the sandpaper belt are connected to the first synchronous wheel and the second synchronous wheel for transmission.

[0009] In order for the sandpaper belt to wrap around the rounded corners of the front panel to be processed, a third synchronous wheel is rotatably connected to the support plate. The third synchronous wheel is located between the first synchronous wheel and the second synchronous wheel. The diameter of the first synchronous wheel is larger than the diameter of the third synchronous wheel, and the diameter of the third synchronous wheel is larger than the diameter of the second synchronous wheel.

[0010] To drive the deburring mechanism to move, a fixed plate and a driving cylinder are provided on the sliding plate. The fixed plate is fixed to one side of the sliding plate by bolts, and the driving cylinder is horizontally mounted on the fixed plate. The output end of the driving cylinder is connected to the sliding block.

[0011] To limit the movement distance of the deburring mechanism, a first stop screw and a second stop screw are respectively provided on both sides of the sliding block. The first stop screw is horizontally mounted on the fixed plate. One end of the first stop screw is threadedly connected to the fixed seat fixed on the fixed plate, and the other end passes through the bottom of the driving cylinder and can abut against one side of the sliding block. One end of the second stop screw is threadedly connected to the fixed seat on the fixed sliding plate, and the other end can abut against the side of the sliding block away from the first stop screw.

[0012] To facilitate height adjustment of the mounting plate, multiple guide screws are vertically fixed on the sliding plate. The mounting plate is slidably connected to the guide screws, and each guide screw is threaded with a fastening nut. The mounting plate is fixed to the guide screw by the fastening screw.

[0013] As a preferred technical solution, the first positioning mechanism includes a first positioning cylinder and a first positioning block connected to the output end of the first positioning cylinder, and the second positioning mechanism includes a second positioning cylinder and a second positioning block connected to the output end of the second positioning cylinder. An angle plate and a cylinder mounting seat are respectively provided on both sides of the mounting plate. The bracket is horizontally mounted and fixed on the angle plate. An adjustment block that can be horizontally adjusted is provided on one side of the bracket. The first positioning cylinder is vertically fixed on the adjustment block, and the second positioning cylinder is tilted and fixed on the cylinder mounting seat.

[0014] To prevent the front panel from tilting up, a crossbeam is provided above the bracket. The crossbeam is fixed to the top of the adjusting block by bolts. Each end of the crossbeam is provided with a vertical shaft that can be adjusted up and down. The lower end of the vertical shaft is rotatably connected to a pressure roller.

[0015] Its advantages over existing technologies are: The deburring device provided by this invention has the advantages of simple structure, high degree of automation, and high grinding efficiency. It can be compatible with cutting equipment and can be linked with cutting equipment to form an automated front panel cutting and deburring production line. After the cutting part of the front panel reaches above the clearance hole, the first positioning block and the second positioning block will move, and the two sides of the front panel will be embedded into the first positioning groove and the second positioning groove respectively, so that the two sides of the front panel are clamped and pressed. Then, the deburring mechanism will move to the position of the front panel, so that the sandpaper belt contacts the part of the front panel to be ground. Then, the sandpaper belt is controlled to rotate to grind the rounded corner area on one side of the front panel and remove the burrs in that part. The positions of the deburring mechanism and the first positioning mechanism can be adjusted according to the length and width of the front panel.

[0016] This device can automatically polish the rounded corners on the outer side of the front panel, achieving high consistency and greatly reducing reliance on manual labor. It also automates the front panel operation and improves the production efficiency of the bucket. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] A preferred embodiment of the present invention provides a deburring device for the front panel of a drawer. This device can be linked with a cutting device to automatically grind the rounded corner area on one side of the cut position of the front panel 24 to remove the burrs generated by the cutting. This facilitates the subsequent installation of decorative strips and prevents injury to workers' hands.

[0021] For details, see Figures 1-3 The device mainly consists of modules such as a base frame, base plate 1, sliding plate 2, mounting plate 3, deburring mechanism 4, first positioning mechanism 5, and second positioning mechanism 6. One side of the device is the feeding direction, and the other side is the discharging direction. The feeding direction will be connected to the cutting equipment, and the discharging direction will be manually unloaded, and the processed front panels 24 will be neatly stacked by manual labor.

[0022] The base plate 1 is horizontally mounted and fixed to the top of the base frame (not shown in the figure), and the two are secured together by bolts. Two parallel slide rails are mounted on the base plate 1, extending along its length. The sliding plate 2 is horizontally slidably connected to these two slide rails via a slider. The deburring mechanism 4 is mounted on the sliding plate 2. By moving the sliding plate 2 closer to or further away from the cutting equipment, the position of the deburring mechanism 4 can be adjusted so that the grinding position can be adjusted according to the different lengths of the cut front panel 24.

[0023] An adjusting screw 12 is provided below the sliding plate 2. The adjusting screw 12 is parallel to the slide rail on the base plate 1, with one end extending between the two slide rails and threadedly connected to the connecting block fixed to the bottom of the sliding plate 2. The other end of the adjusting screw 12 is rotatably connected to the bearing seat fixed to the base plate 1.

[0024] Since the length of the front panel 24 is different and the position of the cutting part is also different, the position of the deburring mechanism 4 is adjusted by rotating the adjusting screw 12 to drive the sliding plate 2 to move.

[0025] A handle 11 is installed on the end of the adjusting screw 12 away from the sliding plate 2 to facilitate rotating the adjusting screw 12.

[0026] See Figure 3 , Figure 6 A guide screw 13 is provided at each of the four corners of the upper surface of the sliding plate 2. The guide screw 13 is vertically arranged and its lower end is threaded to the sliding plate 2. Correspondingly, a through hole is provided at each of the four corners of the mounting plate 3, and the guide screw 13 passes through the through hole. The mounting plate 3 can be moved up and down by the guide screw 13 to adjust its height.

[0027] Two nuts are provided on each guide screw 13, and the nuts are threadedly connected to the guide screw 13. The two nuts are located above and below the mounting plate 3, respectively. After the height of the mounting plate 3 is adjusted, tightening the two nuts will clamp and fix the mounting plate 3 onto the guide screw 13.

[0028] The height at which the mounting plate 3 is inserted is determined by the thickness of the front panel 24.

[0029] like Figure 6 As shown, a support plate 16 is provided above the mounting plate 3. The support plate 16 is fixedly installed on the mounting plate 3 by bolts. The support plate 16 is used to support the front panel 24, which is convenient for the deburring mechanism 4 to grind it.

[0030] Both the mounting plate 3 and the support plate 16 have through holes extending vertically to facilitate the deburring mechanism 4 passing through these holes to grind the front panel 24. These holes extend along the width of the front panel 24, providing sufficient space for the deburring mechanism 4 to move.

[0031] When it is necessary to deburr the front panel 24, the deburring mechanism 4 will approach the part of the front panel 24 to be polished and polish it. When the front panel 24 is polished, the deburring mechanism 4 will move away from the front panel 24, and the cutting device connected to the deburring device will push the subsequently cut front panel 24 forward. The polished front panel 24 will be pushed out of the deburring device by the front panel 24 behind it, thus completing the automatic loading and unloading.

[0032] like Figure 5 As shown, the deburring mechanism 4 mainly consists of a sliding block 401, a support plate 404, a sandpaper belt 409, a first synchronous pulley 405, a second synchronous pulley 406, a third synchronous pulley 407, and a motor 408. Two slide rails are fixedly installed on the sliding plate 2, located below the clearance hole and extending in the same direction as the clearance hole. The bottom of the sliding block 401 is horizontally slidably connected to these two slide rails.

[0033] An inclined plate 402 is provided on one side of the sliding block 401. The inclined plate 402 can be integrally formed with the sliding block 401, or it can be fixedly installed on the sliding block 401 by screws. A motor fixing plate 403 is provided on the inclined plate 402. The motor 408 is located on the upper side of the inclined plate 402 and fixedly installed on the motor fixing plate 403. The output end of the motor 408 is connected to the first synchronous pulley 405 and is used to drive the first synchronous pulley 405 to rotate.

[0034] The support plate 404 is also inclined and is connected to the motor fixing plate 403 via a connecting plate. The second synchronous pulley 406 is rotatably connected to the upper end (i.e., the narrowest end) of the support plate 404, and the third synchronous pulley 407 is rotatably connected to the support plate 404 and close to the second synchronous pulley 406.

[0035] Two of each of the second and third synchronous pulleys 406 and 407 are symmetrically distributed on both sides of the support plate 404. The second, third, and first synchronous pulleys 406 and 407 are all located on the same straight line. The sandpaper belt 409 is annular, with its two ends fitted onto the first and second synchronous pulleys 405 and 406, cooperating with the third synchronous pulley 407 to provide a transmission function. The motor 408 drives the first synchronous pulley 405 to rotate, thereby driving the sandpaper belt 409 to rotate through the other two synchronous pulleys. The abrasive surface of the sandpaper belt 409 faces outwards, polishing the areas of the front panel 24 to be sanded and removing burrs.

[0036] The diameter of the first synchronous pulley 405 is larger than that of the third synchronous pulley 407, and the diameter of the third synchronous pulley 407 is larger than that of the second synchronous pulley 406. Therefore, when the three synchronous pulleys rotate, the second synchronous pulley 406 has the fastest linear speed, and the sandpaper belt 409, which is close to the second synchronous pulley 406, also rotates the fastest, which is beneficial for removing burrs.

[0037] Since there is an appropriate distance between the second synchronous wheel 406 and the third synchronous wheel 407, the sandpaper belt 409 can be recessed into the space between the second synchronous wheel 406 and the third synchronous wheel 407 to form a corner wrapping, which wraps the rounded corner of the part to be sanded on the front panel 24. During sanding, the burrs generated by the previous cutting process in the rounded corner area are removed.

[0038] The width of the support plate 404 gradually decreases from bottom to top, which is adapted to the diameter variation of the three synchronous pulleys. The diameter of the first synchronous pulley 405 is larger than the maximum width of the support plate 404 to ensure that the synchronous pulley does not interfere with the rotation of the sandpaper belt 409 when it rotates. Therefore, the support plate 404 is wrapped around the middle area of ​​the sandpaper belt 409.

[0039] like Figures 3-4 As shown, a fixed plate 7 is provided on one side of the sliding plate 2. The fixed plate 7 is perpendicular to the sliding plate 2, and one end of it is fixed to the sliding plate 2 by screws, close to the slide rail on the sliding plate 2. The other end extends outward. Two corner plates 23 are provided on the fixed plate 7, and the corner plates 23 are fixed to the fixed plate 7 by screws. The two ends of the drive cylinder 8 are respectively fixed to the two corner plates 23. The output end of the drive cylinder 8 is connected to the baffle 410 on the sliding block 401. The drive cylinder 8 drives the sliding block 401 to move, thereby controlling the sandpaper belt 409 to move closer to or away from the area to be sanded on the front panel 24.

[0040] The upper side of the sandpaper belt 409 (i.e. the side closest to the second synchronous pulley 406) extends through the clearance hole to the top of the mounting plate 3.

[0041] See also Figure 3 A first stop screw 9 is provided below the drive cylinder 8. One end of the first stop screw 9 is threadedly connected to the fixed seat fixed on the fixed plate 7, and the other end passes through the two corner plates 23 in sequence and extends to the moving path of the sliding block 401.

[0042] The first stop screw 9 limits the rearward movement of the sliding block 401 (i.e., the movement towards the side closer to the drive cylinder 8). When the sliding block 401 moves backward into position, the first stop screw 9 can abut against the baffle 410 on the sliding block 401 to limit its movement.

[0043] A handle 11 is installed on the end of the first stop screw 9 away from the sliding block 401 to facilitate manual rotation of the first stop screw 9.

[0044] A second stop screw 10 is provided on the opposite side of the first stop screw 9. The second stop screw 10 is located on the side of the sliding block 401 away from the first stop screw 9. One end of the second stop screw 10 is threadedly connected to the fixed seat fixed on the sliding plate 2, and the other end extends to the moving path of the sliding block 401.

[0045] The second stop screw 10 limits the forward movement of the sliding block 401 (i.e., the movement away from the drive cylinder 8). After the sliding block 401 moves forward into position, the second stop screw 10 can abut against the baffle 410 on the other side of the sliding block 401 to limit its movement.

[0046] A handle 11 is also installed on the end of the second stop screw 10 away from the sliding block 401, so as to facilitate manual rotation of the second stop screw 10.

[0047] In other words, the horizontal distance between the first stop screw 9 and the second stop screw 10 is the distance that the sliding block 401 can move. By rotating and adjusting the distance between the first stop screw 9 and the second stop screw 10, the moving distance of the sliding block 401 can be adjusted.

[0048] When the sliding block 401 moves forward and abuts against the second stop screw 10, it means that the sliding block 401 has moved into place and the sandpaper belt 409 just covers the rounded corner of the part to be sanded on one side of the front panel 24.

[0049] Depending on the width of the front panel 24, the first stop screw 9 and the second stop screw 10 can be adjusted to accommodate the grinding and processing of front panels 24 of different widths.

[0050] like Figures 6-8 As shown, a support 14 is provided on the mounting plate 3. The support 14 is located on one side of the support plate 16 and is fixed to the mounting plate 3 by screws. A bracket 15 is mounted on the support 14 and is horizontally fixed to the support 14 by screws. One end of the bracket 15 extends along the width direction of the front panel 24 to the top of the support plate 16.

[0051] The first positioning mechanism 5 consists of a first positioning cylinder 501 and a first positioning block 502. The first positioning cylinder 501 is vertically fixed on the adjusting block 17, and the adjusting block 17 is mounted on the bracket 15 by bolts. The output end of the first positioning cylinder 501 faces downward, and the first positioning block 502 is connected to the output end of the first positioning cylinder 501 to control the up and down movement of the first positioning block 502.

[0052] An adjustment hole 1501 is provided on the bracket 15, which extends along the length of the bracket 15. A bolt passes through the adjustment hole 1501 and is threadedly connected to the adjustment block 17. The adjustment block 17 can be fixed by tightening the bolt. Depending on the width of the front panel 24, the horizontal position of the adjustment block 17 and the first positioning cylinder 501 can be adjusted through the adjustment hole 1501.

[0053] Two bolts are connected to the adjusting block 17. These two bolts are horizontally arranged side by side and pass through the adjusting hole 1501 and are threaded into the adjusting block 17. In this way, the adjusting block 17 can be kept horizontal under the action of the adjusting hole 1501, so that the first positioning cylinder 501 can be kept vertical.

[0054] A first positioning groove 5021 is provided at the bottom of the first positioning block 502 (see...). Figure 9 The shape of the first positioning groove 5021 is adapted to the shape of the front panel 24 near the part to be polished. After the front panel 24 is in place, the first positioning cylinder 501 will drive the first positioning block 502 to move down. The first positioning groove 5021 at the bottom of the first positioning block 502 will fit against one side of the front panel 24 and press the front panel 24 tightly. The side wall of the first positioning groove 5021 will support the side of the front panel 24 near the inside, so as to prevent the front panel 24 from moving to one side when the deburring mechanism 4 polishes it.

[0055] The second positioning mechanism 6 mainly consists of a second positioning cylinder 601 and a second positioning block 602. The second positioning cylinder 601 is obliquely fixedly mounted on a cylinder mounting base 18. The cylinder mounting base 18 is fixedly mounted on the side of the sliding plate 2 away from the support 14 by screws. The cylinder mounting base 18 has an inclined surface, and the second positioning cylinder 601 is mounted on this inclined surface. The output end of the second positioning cylinder 601 faces downward along the inclined surface and is connected to the second positioning block 602.

[0056] The lower side of the second positioning block 602 is provided with a second positioning groove 6021 (see...). Figure 9 The shape of the second positioning groove 6021 is adapted to the shape of the other side of the front panel 24. The second positioning cylinder 601 drives the second positioning block 602 to move downward along the slope, and the flange on the other side of the front panel 24 will be embedded into the second positioning groove 6021 on the second positioning block 602. At the same time, the upper side wall of the second positioning groove 6021 and the flange on the other side of the front panel 24 are inclined to fit together. This can both hold one side of the front panel 24 and press the front panel 24 down. The other side of the front panel 24 is positioned by the obstruction of the first positioning block 502.

[0057] The second positioning block 602 works in conjunction with the first positioning block 502 to center the front panel 24 from different directional dimensions, while pressing the two sides of the front panel 24 to prevent it from warping during sanding.

[0058] like Figure 8 As shown, a crossbeam 19 perpendicular to the support 15 is provided above it. A guide sleeve 20 is welded to each end of the crossbeam 19, and a vertical shaft 21 is installed inside each guide sleeve 20. The vertical shaft 21 and the guide sleeve 20 are connected vertically. The crossbeam 19 is fixed to the adjusting block 17 with screws, so the crossbeam 19 can move laterally together with the adjusting block 17.

[0059] A pressure roller 22 is installed at the lower end of each vertical shaft 21, and the pressure roller 22 is rotatably connected to the lower end of the vertical shaft 21. The pressure roller 22 is used to initially press down the front panel 24 that enters the support plate 16 to prevent the opposite ends of two adjacent front panels 24 from tilting up.

[0060] An adjusting bolt is provided at the upper end of the guide sleeve 20. The adjusting bolt is threaded to the guide sleeve 20 and rotatably connected to the vertical shaft 21. By rotating the adjusting bolt, the vertical shaft 21 can be moved up and down, thereby adjusting the height of the vertical shaft 21, which is also the height of the pressure roller 22, to accommodate front panels 24 of different thicknesses. The vertical shaft 21 and the adjusting bolt can rotate relative to each other, thus allowing adjustment of the angle of the pressure roller 22.

[0061] An air blowing pipe (not shown in the figure) is also provided above the support plate 16. The air blowing port of the air blowing pipe faces the upper surface of the support plate 16. The air blowing pipe uses high-pressure air to blow away the metal debris on the surface of the support plate 16 to prevent the debris from scratching the surface of the front panel 24.

[0062] The deburring device can be linked with the cutting equipment. The first positioning cylinder 501, the second positioning cylinder 601 and the drive cylinder 8 are generally controlled by the air source system (including pneumatic triplet) and solenoid valve. The solenoid valve controls the movement of the valve core through electrical signal, changes the passage of compressed air, and thus drives the piston of cylinder 8 to move in both directions.

[0063] The cutting equipment has corresponding sensors to detect whether the long plate has been cut. After the front panel 24 is cut off from the long plate, the long plate will be conveyed by the conveyor belt to the direction of the deburring mechanism 4. The cut front panel 24 will be pushed backward by the long plate behind it until the cut part of the front panel 24 reaches directly above the clearance hole on the support plate 16. At this time, the system will send a signal to the cylinder control mechanism, and the first positioning cylinder 501, the second positioning cylinder 601 and the drive cylinder 8 will work to carry out the next deburring process.

[0064] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
