Description

Technical Field

[0001] This invention relates to the field of edge banding machine technology, specifically to an edge banding device for office desks. Background Technology

[0002] Edge banding, as the name suggests, involves sealing the side walls of boards with edge banding strips. After edge banding, the side walls of the boards have a smoother finish. Moreover, since boards themselves have a strong odor, such as formaldehyde, edge banding can also block formaldehyde, reducing the explosive release of formaldehyde and improving the living environment.

[0003] Edge banding is generally divided into three types: fully automatic, semi-automatic, and manual. Fully automatic edge banding uses multiple robotic arms and a control system to press and rotate the board, causing the edge banding strip to move and adhere along the side wall of the board. Semi-automatic edge banding generally requires manual adjustment of the board's position so that the side wall of the board is close to the position of the rotating and unfolded edge banding strip, allowing the edge banding strip to adhere to the side wall of the board. Manual edge banding is entirely done by manually attaching the edge banding strip to the side wall of the board.

[0004] The main advantage of semi-automatic edge banding devices is that their cost and operating cost are lower than those of fully automatic edge banding machines. They can achieve high-quality edge banding with manual assistance. However, during the edge banding process, manual intervention is required to maintain downward pressure on the board at the edge banding location. Furthermore, if the edges of the board are not treated before edge banding, gaps can easily appear in the edge banding due to dust after banding, resulting in poor edge banding quality. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides an edge banding device for office desks, which solves the problems mentioned in the background above.

[0006] This invention provides the following technical solution:

[0007] Includes: an edge banding pallet hopper, a material filling bin installed on top of the edge banding pallet hopper, an office desk board installed on top of the edge banding pallet hopper, edge banding strips placed inside the material filling bin, an edge banding rotating pressure shaft driven by a motor on top of the edge banding pallet hopper, and an edge banding pressure roller sleeved on the edge banding rotating pressure shaft.

[0008] Also includes:

[0009] A support crossbeam is installed on top of the edge sealing rotating pressure shaft. A reinforcing screw is fixed on the top of the support crossbeam. An assembly kit is externally engaged with the reinforcing screw. A functional insert plate is fitted on the outside of the assembly kit. A pressing vertical cylinder is fixed on the other end of the functional insert plate. A screw hole is longitudinally opened in the center of the pressing vertical cylinder.

[0010] The downward adjustment screw is spirally connected in the screw hole. The front end of the downward adjustment screw passes through the screw hole of the downward pressure cylinder and extends downward and is connected to the adjustment support plate. The bottom end of the adjustment support plate is fixed with the support plate downward pressure chamber. A movable downward pressure bottom column is installed at the bottom of the cavity of the support plate downward pressure chamber. A freely rotating ball is embedded in the bottom of the downward pressure bottom column.

[0011] The pressing adjustment mechanism is located between the pressing adjustment screw and the pressing base column;

[0012] The positioning insert is longitudinally sleeved outside the assembly kit. The outer wall of the positioning insert is rotatably sleeved with a ring insert plate. The surface of the ring insert plate has a through hole, and an assembly horizontal insert is inserted through the through hole. The bottom end of the positioning insert is rotatably connected to a driven shaft. The upper half of the driven shaft is connected to the sealing edge rotating pressure shaft through a transmission belt.

[0013] The cleaning roller head is installed at the bottom of the driven coupling. The bottom of the horizontal insert is rotatably connected to the baffle rod. A side baffle is inserted inside the baffle rod and is in contact with the side wall of the office desk.

[0014] Furthermore, an outer edge plate is fixed to the outer wall of the end of the assembly horizontal insert, and a sliding groove is opened laterally on the surface of the baffle rotating rod, allowing the side baffle to move laterally along the sliding groove.

[0015] Furthermore, a groove is provided at the top of the end of the side baffle, and an outer edge spring is installed in the groove. The other end of the outer edge spring is connected to the bent part of the outer edge plate.

[0016] Furthermore, a limiting baffle is fixed to one side at the top of the positioning insert, and a limiting spring is installed on the surface of the limiting baffle. The other end of the limiting spring is connected to the side wall of the ring insert.

[0017] Furthermore, the interior of the functional insert and the positioning insert is provided with a groove that matches the shape of the assembly kit. The surface of the edge sealing tray compartment is provided with a dust suction slot. A dust suction device is installed on one side of the edge sealing tray compartment. The dust suction device and the dust suction slot are connected to the cavity inside the edge sealing tray compartment.

[0018] Furthermore, the pressing adjustment mechanism includes a pressing spring, a pressing adjustment plate, a driving adjustment screw, and a positioning adjustment nut. The pressing spring is connected to the top of the pressing base column, the pressing adjustment plate is connected to the top of the pressing spring, the driving adjustment screw is connected to the top of the pressing adjustment plate, and the positioning adjustment nut is engaged and sleeved on the outside of the driving adjustment screw.

[0019] Furthermore, the positioning adjusting nut is rotatably connected to the contact part of the pressing adjusting screw, and the bottom of the pressing adjusting screw is provided with an opening for driving the adjusting screw to extend into it. The front end of the driving adjusting screw is embedded in the pressing adjusting plate and allows the driving adjusting screw to rotate freely.

[0020] Furthermore, an assembly side slot is provided on the surface of the pressing vertical cylinder part, and a positioning insert is slidably installed in the slot of the assembly side slot. A horizontal plate is fixed on the side wall of the positioning insert, and the other end of the horizontal plate is connected to another set of pressing vertical cylinder parts.

[0021] Furthermore, the slot on the assembly side is provided with slot positioning holes with an arc-shaped spacing, and the positioning insert and the insert plate are equipped with U-shaped positioning rods. The two sets of positioning rods are distributed opposite each other, and several sets of springs are set between the two sets of positioning rods.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] This application utilizes a support frame plate to allow the assembly kit to be spirally installed on top of the support frame plate. The assembly kit can be fitted with functional insert plates and positioning inserts. A ring insert plate is rotatably fitted over the positioning insert, and a driven shaft is rotatably connected to the bottom of the ring insert plate. A transmission belt connects the edge-sealing rotating pressure shaft to the driven shaft. Thus, when the edge-sealing rotating pressure shaft rotates, the driven shaft also rotates. After the driven shaft rotates, the cleaning roller head can adhere to the side wall of the desk tabletop. Before the edge-sealing adhesive strip adheres to the side wall of the desk tabletop, the rotation of the cleaning roller head performs a rotating cleaning operation on the surface of the desk tabletop, improving the side wall of the desk tabletop. To improve the cleanliness and thus the edge sealing quality, and to reduce the impact of dust from cleaning on subsequent production, a baffle rod and a side baffle are installed on one side of the cleaning roller head. The side baffle can be driven by the elasticity of the outer edge spring to be as close as possible to the side wall of the office desk. Therefore, through the isolation of the side baffle, and with the dust suction nozzle and dust suction device, the dust is prevented from moving to the side as much as possible, so as not to affect the subsequent edge sealing and further improve the edge sealing quality. At the same time, under the action of the limiting spring and the limiting baffle, the cleaning roller head and the side baffle are brought as close as possible to the side wall of the office desk, improving the cleaning quality of the side wall of the office desk.

[0024] This application, by fitting the functional insert piece outside the assembly kit, allows the side baffle to be positioned on one side of the edge-sealing pressure roller. By spirally pushing the downward adjustment screw, the ball at the bottom of the support plate's pressure chamber can press down on the upper part of the office desk panel. Simultaneously, the elastic drive of the downward pressure spring ensures that the ball presses down on the office desk panel, maintaining its stability without affecting its normal movement or edge-sealing work. Furthermore, the intensity of the ball's downward pressure action can be adjusted via the pressing adjustment mechanism, further improving stability during the edge-sealing process, enhancing edge-sealing quality, and reducing edge-sealing deviations.

In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0035] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-8 The system includes: an edge-sealing tray 1, a material filling tray 2 installed on top of the edge-sealing tray 1, an office desk 5 installed on top of the edge-sealing tray 1, an edge-sealing adhesive strip 3 placed in the material filling tray 2, an edge-sealing rotating pressure shaft 11 driven by a motor on top of the edge-sealing tray 1, and an edge-sealing pressure roller 4 sleeved on the edge-sealing rotating pressure shaft 11. The roll of the edge-sealing adhesive strip 3 is embedded in the material filling tray 2, and a driving device is set in the material filling tray 2 so that the edge-sealing adhesive strip 3 can be evenly pulled out. At the same time, a driving device is also set at the bottom of the edge-sealing rotating pressure shaft 11. During the edge-sealing process, the side wall of the office desk 5 is brought close to the front end of the edge-sealing adhesive strip 3, and the office desk 5 and the edge-sealing adhesive strip 3 are brought close to the edge-sealing pressure roller 4. The position of the office desk 5 is pushed, so that different positions of the side wall of the office desk 5 move towards the edge-sealing pressure roller 4, thereby using the edge-sealing adhesive strip 3 to perform edge-sealing work on the office desk 5.

[0038] The supporting crossbeam plate 8 is installed on the top of the edge sealing rotating pressure shaft 11, and the top of the edge sealing rotating pressure shaft 11 can rotate at the bottom of the supporting crossbeam plate 8. At the same time, a bracket is set on the side wall of the supporting crossbeam plate 8, which is connected to the top of the edge sealing tray 1, thereby improving the stability of the supporting crossbeam plate 8. A reinforcing screw 9 is fixed on the top of the supporting crossbeam plate 8, and an assembly kit 10 is externally engaged with the reinforcing screw 9. A functional insert plate 14 is sleeved on the outside of the assembly kit 10, and a positioning insert cylinder 31 is also provided above the functional insert plate 14. The driven coupling shaft 13 is also sleeved on the outside of the assembly kit 10, so that the positioning insert cylinder 31 and the functional insert plate 14 have grooves that are adapted to the shape of the assembly kit 10. After the positioning insert cylinder 31 and the functional insert plate 14 slide into the outside of the assembly kit 10, the angle remains unchanged.

[0039] The other end of the functional insert 14 is fixedly provided with a pressing vertical cylinder 15. A screw hole is longitudinally opened in the center of the pressing vertical cylinder 15. A pressing adjustment screw 16 is screwed into the screw hole. The front end of the pressing adjustment screw 16 extends downward through the screw hole of the pressing vertical cylinder 15 and is connected to an adjusting support plate 17. A support plate pressing chamber 18 is fixedly provided at the bottom end of the adjusting support plate 17. A movable pressing bottom column 19 is installed at the bottom of the cavity of the support plate pressing chamber 18. A freely rotatable ball 21 is embedded in the bottom of the pressing bottom column 19. The pressing adjustment screw 16 rotates to adjust the pressure. The height of the support plate pressure chamber 18 can be adjusted by turning, thereby adjusting the height of the ball bearing 21. During the movement of the office desk tabletop 5, the ball bearing 21 presses down on the top of the office desk tabletop 5 to prevent it from warping when the office desk tabletop 5 is edge-sealed, thus improving the edge-sealing quality. The height of the ball bearing 21 can be adjusted to accommodate boards of different thicknesses. At the same time, since the functional insert plate 14 is fitted and matched with the assembly kit 10, the orientation of the functional insert plate 14 can be adjusted, thereby changing the position of the ball bearing 21, making the usage position more flexible.

[0040] The pressing adjustment mechanism is located between the pressing adjustment screw 16 and the pressing base post 19. The pressing adjustment mechanism includes a pressing spring part 20, a pressing adjustment plate 22, a driving adjustment screw 23, and a positioning adjustment nut 24. The pressing spring part 20 is connected to the top of the pressing base post 19, the pressing adjustment plate 22 is connected to the top of the pressing spring part 20, the driving adjustment screw 23 is connected to the top of the pressing adjustment plate 22, and the positioning adjustment nut 24 is engaged and sleeved on the outside of the driving adjustment screw 23. The positioning adjustment nut 24 is rotatably connected to the contact part of the pressing adjustment screw 16. The bottom of the pressing adjustment screw 16 has an opening for the driving adjustment screw 23 to extend into, and the front end of the driving adjustment screw 23 is embedded in the pressing adjustment plate. Within 22, the drive adjusting screw 23 can rotate freely. After the ball 21 is attached to the upper end of the office desk 5, the downward pressure intensity of the ball 21 can be changed by adjusting the position of the drive adjusting screw 23. Since the positioning adjusting nut 24 can rotate at the bottom of the downward adjusting screw 16 and the positioning adjusting nut 24 will not come off, as the positioning adjusting nut 24 rotates, the drive adjusting screw 23 will move longitudinally in the opening at the bottom of the downward adjusting screw 16. When the drive adjusting screw 23 moves downward, it will provide downward pressure to the downward adjusting plate 22, so that the downward spring part 20 is further compressed. Therefore, the downward pressure intensity of the ball 21 on the upper part of the office desk 5 can be further improved, and the quality of the edge banding can be further improved.

[0041] The positioning insert 31 is longitudinally sleeved outside the assembly kit 10. A ring-shaped insert plate 32 is fixed to the outer wall of the positioning insert 31. The ring-shaped insert plate 32 has an L-shaped structure and a through hole on its surface. An assembly horizontal insert 33 passes through the through hole. The assembly horizontal insert 33 can be perpendicular to the longitudinal structure of the ring-shaped insert plate 32. After the assembly horizontal insert 33 is engaged with the ring-shaped insert plate 32, a screw hole is provided. The position of the assembly horizontal insert 33 can be restricted by screws, facilitating the assembly and disassembly of the assembly horizontal insert 33. A driven coupling 1 is rotatably connected to the bottom end of the positioning insert 31. 3. The upper part of the driven shaft 13 is connected to the edge-sealing rotating pressure shaft 11 via a transmission belt 12. The rotation of the edge-sealing rotating pressure shaft 11 drives the driven shaft 13 to rotate under the drive of the transmission belt 12. The top of the driven shaft 13 is rotatably connected to the bottom of the ring insert plate 32. Therefore, as the driven shaft 13 rotates, the cleaning roller head 30 installed at the bottom of the driven shaft 13 rotates. The outer wall of the cleaning roller head 30 is attached to the side wall of the office desk 5, thus cleaning the side wall of the office desk 5 can be performed by rotating the cleaning roller head 30. A baffle rod part 34 is rotatably connected to the bottom of the mounting horizontal insert 33. A side baffle 35 passes through the baffle rod part 34 and is attached to the side wall of the office desk 5.

[0042] An outer edge plate 36 is fixed to the outer wall of the end of the mounting horizontal insert 33. A sliding groove is opened laterally on the surface of the baffle rotating rod part 34, and the side baffle 35 can move laterally along the sliding groove. A groove is opened at the top of the end of the side baffle 35, and an outer edge spring 37 is installed in the groove. The other end of the outer edge spring 37 is connected to the bent part of the outer edge plate 36. Through the elastic drive of the outer edge spring 37, the side baffle 35 is made as close as possible to the side wall of the office desk tabletop 5 in the sliding groove of the baffle rotating rod part 34, thereby improving the sealing effect of the side baffle 35 on the side of the cleaning roller head 30. In this way, after the cleaning roller head 30 cleans the side of the office desk tabletop 5, impurities cannot pass through the side baffle 35, thus improving the subsequent edge sealing quality. The rotation angle between the baffle rotating rod part 34 and the ring insert plate 32 is 0-60°. A limiting baffle 39 is fixed to one side of the top of the positioning insert part 31. A limiting spring 40 is installed on the surface of the limiting baffle 39. The other end of the limiting spring 40 is connected to the side wall of the ring insert 32. Driven by the limiting spring 40, the entire ring insert 32 rotates and is sleeved outside the positioning insert part 31, while moving as close as possible to the desk tabletop 5, so that the cleaning roller head 30 is always in contact with the side wall of the desk tabletop 5. A dust suction slot 6 is opened on the surface of the edge sealing tray 1. A dust suction device 7 is installed on one side of the edge sealing tray 1. The dust suction device 7 and the dust suction slot 6 are connected to the cavity inside the edge sealing tray 1. Since the impurities swept out by the cleaning roller head 30 can be restricted by the side baffle 35 and sucked into the dust suction slot 6 by the airflow, the dust is collected in the dust suction device 7.

[0043] The surface of the pressing vertical cylinder 15 is provided with an assembly side slot 25. A positioning insert 27 is slidably installed in the slot of the assembly side slot 25. A horizontal plate 28 is fixed to the side wall of the positioning insert 27. The other end of the horizontal plate 28 is connected to another set of pressing vertical cylinders 15. The slot of the assembly side slot 25 is provided with slot positioning holes 26 with arc-shaped spacing. U-shaped positioning rods 29 are installed in the positioning insert 27 and the horizontal plate 28. The two sets of positioning rods 29 are oppositely distributed, and several sets of springs are set between the two sets of positioning rods 29. In order to further improve the pressure stability on the top of the office desk tabletop 5 and improve the edge sealing quality, the positioning insert 27 can be inserted into the assembly side slot 25. In order to keep the positioning insert 27 standing stably in the assembly side slot 25, it can be pressed down by pressing down the upper and lower parts. The positioning rod 29 is retracted into the insert block 28 and the positioning insert 27. After the positioning insert 27 reaches the designated position, the positioning rod 29 is released. The spring causes the positioning rod 29 to extend upward and downward from the positioning insert 27, thereby locking the positioning rod 29 into the slot positioning hole 26, thus restricting the position of the insert block 28. The insert block 28 is connected to another set of pressing vertical cylinders 15, so the ball bearing 21 can be used to press down on different positions of the office desk 5 by different numbers of times.
