Description

Technical Field

[0001] This utility model relates to the field of edge banding manufacturing technology, specifically to an edge banding rewinding machine. Background Technology

[0002] After furniture boards are processed, the cross-sections are usually exposed, which is not only unsightly, but also allows harmful gases (such as formaldehyde and benzene) inside the board to evaporate. The exposed cross-sections are also very easy to wear. Therefore, all furniture boards must be sealed with edge banding strips after processing. After edge banding strips are manufactured, printed, embossed, and dried, they must be rolled up for easy packaging, storage, and transportation. Currently used edge banding strip rolling equipment can only roll up a single type or variety of edge banding strip within a single service cycle. Furthermore, the selection of the edge banding strip roll head size is tied to the setting of the position parameters of the edge banding strip traction device. In other words, the position parameters of the edge banding strip traction device need to be set according to the selected edge banding strip roll head size to ensure that the traction device can accurately pull the edge banding strip to the outer diameter of the corresponding size roll head and clamp it to complete the traction feeding and prepare for the next rolling action. Therefore, when rolling different types of edge banding strips on the same rolling equipment, it is necessary to change the edge banding strip roll head to the corresponding size and simultaneously modify the position parameters of the edge banding strip traction device corresponding to the corresponding size roll head to ensure accurate feeding and clamping of the edge banding strip. This process generally takes several minutes or even longer to set and debug, resulting in low efficiency. Meanwhile, the existing edge banding rewinding equipment required workers to tighten screws and wrenches to secure the rewinding head to the rewinding lifting shaft when installing or replacing the rewinding head. Disassembly then required loosening the screws with a wrench. Clearly, this method of feeding and installing / removing the edge banding head was extremely cumbersome and inefficient. Such frequent and prolonged operations increased worker fatigue, severely impacted rewinding efficiency, hindered cost control, and failed to effectively meet the current demand for large-scale, high-volume, and multi-type edge banding rewinding.

[0003] In conclusion, it is necessary to further improve the existing technology. Summary of the Invention

[0010] As a preferred embodiment of this utility model: the feeding and winding head linkage assembly includes a first linkage plate and a fourth linkage plate; the tail end and middle section of the first linkage plate are hinged to the upper part of the feeding mounting frame or the shearing mounting shell, and the head end is fixedly connected to the tail end of the fourth linkage plate; the head end of the fourth linkage plate is hinged to the winding head rotary transmission plate through a rotating shaft.

[0011] As a preferred embodiment of this utility model: the edge banding feeding mechanism further includes an edge banding thickness measuring roller; the edge banding thickness measuring roller is installed on the upper part of the feeding end of the feeding mounting frame, and one axial end of the roller is also matched with an angle position meter for real-time monitoring of the rotation angle change of the edge banding thickness measuring roller.

[0012] As a preferred embodiment of this utility model: the edge banding feeding mechanism further includes an edge banding limiting bracket; the edge banding limiting bracket is installed on the upper part of the feeding end of the feeding mounting frame and is located on the discharge side of the edge banding thickness measuring roller.

[0013] As a preferred embodiment of this utility model: the winding machine further includes an edge sealing strip pushing mechanism; the edge sealing strip pushing mechanism is disposed on one side of the worktable and is used to push the edge sealing strip roll after winding out of the rotating worktable.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects: This utility model features a simple and reasonable structural design, making it easy to operate. In particular, the edge banding strip feeding mechanism employs a rotatable design, and a linkage component between the feeding and winding heads establishes a connection between the feeding mechanism and the winding head. This allows the winding head to rotate and swing synchronously with the feeding mounting frame of the edge banding strip feeding mechanism, ensuring that the feeding direction of the edge banding strip remains parallel to the outer diameter tangent of the winding head. No other adjustments or settings are required; simply manually operating the rotating drive component of the feeding mounting frame according to the size of the winding head allows for immediate feeding, significantly reducing worker fatigue. Furthermore, compared to the previous method of resetting the position parameters of the edge banding strip feeding mechanism using electronic instruments such as PLC controllers and performing reversals each time, this design significantly improves efficiency. In terms of re-adjustment, the operation is more convenient, the time is greatly reduced, and the feeding and clamping efficiency of the edge banding strip is significantly improved. Furthermore, the rotating drive component of the feeding mounting frame used in this invention can lock and fix the position of the edge banding strip feeding mechanism immediately after the position of the edge banding strip feeding mechanism is adjusted, ensuring the stability of the feeding process. This feeding and feeding method of this invention can be applied to different types of edge banding strip rewinding heads, without the need to set corresponding position parameters or make adjustments for different types of edge banding strip rewinding heads. Compared with the original operation method that uses high-cost electronic control devices such as electronic control instruments to set different feeding and feeding angle or position parameters and make adjustments according to different types of edge banding strip rewinding heads, the operation is simpler and more efficient, the equipment manufacturing cost is also lower, and it is beneficial to the enterprise's production cost control.

[0015] The disassembly and assembly of the edge banding retractor of this utility model eliminates the need for fasteners and wrenches. It adopts a lever-type structure design, which makes the disassembly and assembly of the edge banding retractor and the retractor shaft tube more convenient, faster, and cheaper. The disassembly and assembly of the edge banding retractor can be completed in as little as 2-5 seconds, which greatly reduces the disassembly and assembly time of the edge banding retractor and significantly improves the disassembly and assembly efficiency of the edge banding retractor.

[0016] The rewinding wheel of this utility model consists of at least two rewinding blocks, and adjacent rewinding blocks are detachably fitted and inserted into each other by horizontal positioning pins and horizontal positioning holes. This makes the rewinding wheel more stable in the gathered state, ensuring more stable rotation of the rewinding wheel during high-speed winding in the gathered state. It also prevents the individual rewinding blocks from loosening or shaking during high-speed rotation, effectively guaranteeing the winding quality of the edge sealing strip winding product.

[0017] This invention also installs a sensor on the rotating transmission plate of the winding head to sense changes in the position of the edge banding clamping component. By using the sensor in conjunction with the electrical control box, the timing of the edge banding clamping component and the edge banding feeding mechanism is made more precise, which further improves the edge banding clamping efficiency and ensures that the edge banding winding process is safer and more stable.

[0018] This invention also includes a thickness measuring roller for the edge banding strip, with an angle positioner connected to one axial end for real-time monitoring of the rotation angle changes of the roller. The angle positioner works in conjunction with the electrical control box, making the winding action of the edge banding strip winding mechanism, the shearing action of the edge banding strip cutting mechanism, and the pushing action of the edge banding strip pushing mechanism more precise and efficient, ensuring accurate shearing of the edge banding strip and further improving winding efficiency. Simultaneously, a vertical limiting bracket suitable for edge banding strips of different widths is provided on the discharge side of the thickness measuring roller, ensuring greater stability of the edge banding strip during feeding and winding.

[0019] This invention can effectively meet the current demand for large-scale, high-volume, and multi-type edge banding strips, and is suitable for promotion and application. Attached Figure Description

The connecting rod 5722 is vertically fixed to the top center of the expansion block body 5721, and its upper end moves from bottom to top through the mounting shaft 571 and extends outward above the mounting shaft 571. The extended end is hinged to the end of the cylinder rod of the winding head clamping drive cylinder 58 to ensure that the cylinder rod of the expansion block drive cylinder 58 only applies axial force to the expansion block 572, and the cylinder rod of the expansion block drive cylinder 58 does not rotate when the expansion block 572 rotates.

[0048] The slide plate 573 is fitted to the bottom of the mounting shaft 571. A cross-shaped groove is formed by the intersection of horizontal and vertical lines in the center of the slide plate.

[0052] The edge banding clamping component 577 is fixedly installed on one side of the mounting shaft 571. Its upper end is fixedly connected to the mounting shaft 571, and its lower end extends straight downward toward the radial outer side of the take-up roller 576. When the expansion block 572 moves downward under the drive of the take-up head clamping drive device, the expansion block body 5721 expands a pair of bearing assemblies 574 and two semi-circular take-up blocks 5761 together to press the edge banding between the edge banding clamping component 577 and the outer circumferential surface of the take-up roller 576, thereby achieving edge banding clamping.

[0053] like Figure 6-7 As shown, in this embodiment, the winding head clamping drive device adopts a winding head clamping drive cylinder 58, which is matched and installed above the middle arch of the winding mounting bridge 51 and connected to the external air source and electrical control box 6 through a solenoid valve; wherein, the piston rod of the winding head clamping drive cylinder 58 extends downward into the winding head mounting shaft tube 56 and is hinged to the upper end of the mounting shaft 571 of the edge sealing strip winding head 57.

[0054] like Figure 6-8 As shown, one end of the take-up head rotary transmission plate 59 is fixedly installed on the upper end of the take-up head rotating shaft tube 56, located outside the shaft tube between a pair of support plates 551. The other end extends horizontally outward from the take-up head rotating shaft tube 56, and the extended end is hinged to one end of the feeding and take-up head linkage assembly 7. Simultaneously, a sensing probe 591 is also installed on the take-up head rotary transmission plate 59. This sensing probe 591 is electrically connected to the control box 6 and is used to sense the position of the edge sealing strip clamping component 577 of the edge sealing strip take-up head 57. After detecting that the edge sealing strip clamping component 577 is aligned with the edge sealing strip feeding mechanism 2, it transmits the alignment signal back to the PLC controller inside the control box 6, which then controls the actions of other corresponding mechanisms.

[0055] like Figure 4 and Figure 6-7As shown, the feeding and winding head linkage assembly 7 is matched and connected between the shearing mounting shell 31 of the edge banding shearing mechanism 3 and the winding head rotation transmission plate 59 of the edge banding winding mechanism 5, and includes a first linkage plate 71, a second linkage plate 72, a third linkage plate 73 and a fourth linkage plate 74. The tail end of the first linkage plate 71 is hinged to a second linkage plate 72, which is hinged to the shearing mounting shell 31 of the edge banding strip shearing mechanism 3 on one side of the edge banding strip traction mounting frame 241. The middle section of the first linkage plate 71 is hinged to a third linkage plate 73, which is hinged to the shearing mounting shell 31 of the edge banding strip shearing mechanism 3 on one side of the edge banding strip traction mounting frame 241. The head end of the first linkage plate 71 is fixedly connected to the tail end of the fourth linkage plate 74. The head end of the fourth linkage plate 74 is hinged to the end of the take-up head rotary transmission plate 59 that extends horizontally to the radially outer side of the take-up head mounting shaft tube 56 via a rotating shaft 75. After the edge banding rewind head 57 is installed on the rewind head mounting tube 56, when the worker manually swings the feeding mounting frame 21 of the edge banding feeding mechanism 2, the feeding mounting frame 21 will drive the first linkage plate 71, the second linkage plate 72, the third linkage plate 73 and the fourth linkage plate 74 to swing synchronously. In turn, the swinging fourth linkage plate 74 will drive the rewind head mounting tube 56 of the edge banding rewinding mechanism 5 to rotate. During the rotation, the rewind head mounting tube 56 will drive the edge banding rewind head 57 to rotate at the same angle as the feeding mounting frame 21 in the horizontal direction. Since the edge banding rewind head 57 always rotates synchronously and at the same angle as the feeding mounting frame 21 of the edge banding feeding mechanism 2, the outer diameter tangent of the rewinding wheel 576 of the edge banding rewind head 57 will always remain parallel to the direction in which the edge banding is driven by the edge banding feeding mechanism 2. Precise feeding of the edge banding can be achieved without other operations.

[0056] The electrical control box 6 is located on one side of the chassis 1; in this embodiment, the electrical control box 6 is installed on the upper side of the shearing mounting shell 31 of the edge banding shearing mechanism 3. The electrical control box 6 includes a housing; inside the housing are components such as a PLC controller, servo driver, switching power supply, fuse holder, and leakage current protector; outside the housing are a touch screen, emergency stop switch button, start switch button, pause switch button, and quick rewind button. The switching power supply provides 24V DC power, and its power output terminals are connected to the power input terminals of the PLC controller, the servo driver, and the touch screen, respectively; the power input terminal of the leakage current protector is connected to a 220V AC power supply for overall power protection. The fuse holder is connected in series with the power output terminal of the leakage current protector to provide overcurrent protection for the PLC controller, servo driver, and solenoid valve. The high-speed output terminal of the PLC controller is connected to the pulse input terminal of the servo driver; the direction signal output terminal of the PLC controller is connected to the direction input terminal of the servo driver; the servo enable signal terminal of the PLC controller is connected to the enable terminal of the servo driver; and the output terminal of the servo driver is connected to the power line of the servo drive motor. Simultaneously, the signal input terminal of the PLC controller is also connected to the signal output terminal of the sensing probe, and the power supply terminal of the sensing probe is connected to a switching power supply. The high-speed counter terminal of the PLC controller is connected to the signal output terminal of the angle position meter, and the power supply terminal of the angle position meter is connected to a switching power supply. The output terminals of the PLC controller (such as Y0) are respectively connected to the coils of the solenoid valves corresponding to the edge banding traction bidirectional cylinder, the edge banding clamping cylinder, the edge banding shearing drive cylinder, the winding head lifting drive cylinder 53, and the expansion block drive cylinder 58. By controlling the on / off state of the coils, each solenoid valve is opened or closed, thereby controlling the action of the cylinder corresponding to each solenoid valve; and the power supply for each solenoid valve is provided by an independent switching regulated power supply. The normally closed contacts of the emergency stop switch, start switch, pause switch, and quick rewind switch are connected in series to the input terminals (such as X0, X1, etc.) of the PLC controller. The power input terminals of the emergency stop switch, start switch, pause switch, and quick rewind switch are connected to the common terminal of the switching power supply and the PLC controller. The touch screen is connected to the PLC controller via a communication interface (such as RS485 or Ethernet) for parameter setting and status monitoring.

[0057] The main working principle of this utility model is as follows: After the winding machine is powered on, press the start switch button on the control box 6. The edge banding strip winding head 57 descends and aligns with the rotating worktable 13 for positioning and installation. The sensor probe 591 detects whether the position of the edge banding strip clamping component 577 is aligned with the edge banding strip feeding mechanism 2. After receiving the alignment signal from the sensor probe 591, the PLC controller inside the control box 6 controls the edge banding strip clamping cylinder of the edge banding strip traction device 24 to clamp the edge banding strip, and controls the edge banding strip traction bidirectional cylinder to send the edge banding strip clamped by the edge banding strip clamping cylinder to the edge banding strip clamping component 577 and the edge banding strip winding head. Between the outer diameter of 57, the PLC controller inside the electrical control box 6 then controls the winding head clamping drive device to open the winding wheel 576 of the edge banding strip winding head 57 to clamp the edge banding strip between the edge banding strip clamping component 577 and the outer diameter of the edge banding strip winding head 57. Then, the PLC controller inside the electrical control box 6 controls the edge banding strip clamping cylinder to release the edge banding strip and controls the edge banding strip traction bidirectional cylinder to start, bringing the edge banding strip clamping cylinder back to its original position. Then, the PLC controller inside the electrical control box 6 controls the winding drive motor to start, driving the rotating worktable 13 to rotate and drive the edge banding strip winding head 57 to rotate together, so as to wind up the edge banding strip. The edge sealing strip passes between a pair of edge sealing strip thickness measuring rollers 22. If a joint of the edge sealing strip passes by, it will open the two pairs of edge sealing strip thickness measuring rollers 22 at an angle. The angle position sensor connected to the pair of edge sealing strip thickness measuring rollers 22 senses the angle change in real time and transmits the angle signal to the PLC controller inside the electrical control box 6. When the angle reaches the value set on the PLC controller, it proves that a joint of the edge sealing strip has passed by. At this time, the PLC controller quickly issues a command to control the winding drive motor to stop working, so that the rotating worktable 13 stops. The machine rotates, and then the PLC controller controls a pair of edge banding shearing drive cylinders to drive the edge banding shears to descend and cut off the joint of the edge banding. Next, the PLC controller controls the winding head lifting drive cylinder 53 to raise the edge banding winding head 57 and completely detach it from the rotating worktable 13. Finally, the PLC controller controls the edge banding pushing drive cylinder 42 to start, and the edge banding pushing drive cylinder 42 drives the pushing rod to push the wound edge banding product out of the rotating worktable 13. At this point, the winding of one roll of edge banding product is completed.

[0058] This utility model has a reasonable structural design and is easy to operate. In particular, the feeding and rewinding of the edge banding strip are extremely efficient and convenient. The equipment has low manufacturing cost and can effectively meet the needs of high-efficiency rewinding of large-scale, high-volume, and multi-type edge banding strips. It is suitable for promotion and application.
