Description

Technical Field

[0001] This application relates to the technical field of edge banding processing centers, and more specifically, to an edge banding head and an edge banding processing center. Background Technology

[0002] An edge banding processing center is a type of woodworking machinery used for irregularly shaped processing and edge banding. It enables mechanized edge banding operations and is mainly used for processing and edge banding panel wood products such as furniture, kitchenware, and decoration. The quality of edge banding directly affects the quality and grade of the board. The main process of edge banding involves heating and melting the adhesive, applying it to the edge of the edge banding tape, and finally fixing the edge banding tape to the edge of the board. By edge banding the board, it can improve the surface appearance quality of the board, prevent damage to the corners of furniture, kitchenware, and other products during transportation and use, and prevent the veneer from being lifted or peeled off. It can also play a role in waterproofing, sealing the release of harmful gases, and reducing deformation.

[0003] Existing edge banding processing centers often use edge banding tape to band multiple sides or curved surfaces of boards. However, edge banding tape itself has a certain degree of elasticity. Therefore, when the edge banding tape is combined with different sides or curved surfaces of the board, the elasticity can easily lead to weak bonding. Especially in winter, when the board temperature is low, the hot melt adhesive on the edge banding tape cools quickly when bonded to the board, resulting in lower viscosity. Consequently, the edge banding tape adhering to the edge of the board can easily detach, seriously affecting the use of the board. Summary of the Invention

The clamping cylinder 321 pushes the roller seat 323 to move, thereby causing the feeding clamping roller 324 to move closer to or further away from the feeding shaft 313, thus clamping or releasing the edge sealing tape.

[0055] Optionally, the height adjustment mechanism 33 may include a counter 333, a pressing arm 331, a pressing adjustment bracket 34, and a first pressing block 332. The top of the counter 333 can be fixed to the connecting plate 61, and the shaft of the counter 333 can be connected to the pressing adjustment bracket 34. One end of the pressing arm 331 is fixed to the pressing adjustment bracket 34, and the other end is fixed with the first pressing block 332. The side of the pressing arm 331 with the first pressing block 332 is closer to the side of the glue pot assembly 4 where the glue application shaft 45 is located. During height adjustment, the first pressing block 332 contacts the edge sealing tape. The height of the pressing adjustment bracket 34 is adjusted by the counter 333, thereby changing the height of the first pressing block 332 to achieve the height adjustment of the edge sealing tape.

[0056] Optionally, to facilitate the feeding of adhesive granules, the edge banding processing center may also include an adhesive granule feeding module, which can be located within the travel range of the adhesive pot assembly 4 on the edge banding head. This adhesive granule feeding module may include an adhesive granule bin 81, a feeding box 82, a second mounting base 84, and a feeding control unit 83. The bottom of the adhesive granule bin 81 can be fixed to the feeding box 82. The second mounting base 84 is fixed to one side of the feeding box 82, thereby fixing the adhesive granule feeding module to the edge banding processing center. The bottom of the feeding box 82 may have a feeding port, the shape of which can correspond to the inlet 41 at the top of the heating chamber 42. The feeding control unit 83 can be located on one side of the feeding box 82, controlling the opening or closing of the feeding port. The feeding control unit 83 may include a feeding cylinder and a feeding control structure. The feeding control structure is located inside the feeding box 82, and the feeding cylinder is connected to the feeding control structure to control the opening or closing of the feeding port. When feeding is required, the edge banding processing center can move the heating chamber 42 in the edge banding head to below the feeding box 82, and make the inlet 41 of the heating chamber 42 face the feeding port. The feeding control unit 83 opens the feeding port to realize feeding.

[0057] Optionally, in order to transmit the power of the first drive assembly 741 and the second drive assembly 742 to the sealing head, the sealing head may further include an input assembly 1. The top of the input assembly 1 may be connected to the slip ring unit 75 and the rotating shaft 7413 of the first drive assembly 741, and the lower part of the input assembly 1 may be disposed on the connecting plate 61 and drivenly connected to the glue application shaft 45 of the glue pot assembly 4, thereby transmitting the power of the first drive assembly 741 to the glue application shaft 45, and driving the connecting plate 61 to rotate when the second drive assembly 742 is driven to rotate by the slip ring unit 75.

[0058] In one embodiment, the input component 1 may include a transmission block 12, a first transmission seat 13, and a transmission shaft 11. The transmission shaft 11 can be drivenly connected to the rotating shaft 7413 to transmit power to the first drive component 741. The transmission block 12 can be fixed on the first transmission seat 13 and connected to the slip ring unit 75. When the slip ring unit 75 rotates, it drives the transmission block 12 and the first transmission seat 13 to rotate. The bottom of the input component 1 may be equipped with a sprocket, and the transmission shaft 11 can be drivenly connected to the sprocket. The glue application shaft 45 of the glue pot component 4 is drivenly connected to the sprocket.

[0059] Optionally, the glue-applying shaft 45 is located below the connecting plate 61, and the edge-sealing head also includes a swing seat assembly 2. The heating chamber 42 and the swing seat assembly 2 are located on the opposite side of the connecting plate 61, and the glue-applying shaft 45 is located on the side of the heating chamber 42 near the swing seat assembly 2. The swing seat assembly 2 includes an upper swing seat 21, which is rotatably fixed to the connecting plate 61. The swing seat assembly 2 is rotated relative to the connecting plate 61 by rotational fixing, thereby obtaining the space required to clear the glue-applying shaft 45. During edge sealing, the edge-sealing tape first passes through the tape feeding assembly 3, then through the swing seat assembly 2, and finally enters the glue pot assembly 4 to achieve glue application.

[0060] Optionally, one end of the upper swing seat 21 can be fixed to the connecting plate 61 by a rotating pin 211, thereby enabling its rotation relative to the connecting plate 61. Furthermore, a screw or bolt can be provided on the other end of the upper swing seat 21 near the connecting plate 61, and the screw or bolt can be used to fix this end to the connecting plate 61.

[0061] In one embodiment, one end of the upper swing seat 21 is rotatably fixed to the connecting plate 61 by a rotating pin 211, and the other end is provided with a universal bolt 212 and a locking screw 213. A guide pin 611 is provided on the side of the connecting plate 61. The other end of the upper swing seat 21 is relatively fixed to the connecting plate 61 by the guide pin 611, the universal bolt 212 and the locking screw 213.

[0062] Optionally, the swing base assembly 2 includes a cutting unit 22 with a saw blade 224. The cutting unit 22 is fixed below the upper swing base 21 and is used to cut the edge banding tape using the saw blade 224. The cutting unit 22 may include a cutting driver 223, which can be connected to the saw blade 224 in a transmission manner (e.g., via a timing belt) to drive the saw blade 224 to rotate and cut the edge banding tape.

[0063] Optionally, the edge-cutting unit 22 may further include an edge-cutting mounting base 222, a swing base 221, and a swing assembly. The saw blade 224 and the edge-cutting driver 223 (which may be a pneumatic motor) may be disposed on both sides of the edge-cutting mounting base 222. The top of the edge-cutting mounting base 222 may be rotatably connected to the swing base 221 via a pin. The top of the swing base 221 may be fixedly connected to the bottom side of the upper swing base 21. The driving end of the swing assembly may contact the edge-cutting mounting base 222 and push the edge-cutting mounting base 222 to swing, thereby controlling the saw blade 224 away from the edge banding when it is not needed to cut the edge banding and pushing the saw blade 224 closer to the edge banding when it is needed to cut.

[0064] Optionally, to better secure the edge banding during removal and sawing, the swing seat assembly 2 may further include a swing unit 23 equipped with a second drive cylinder 232, a connecting pad 238, a connecting seat 231, a middle swing seat 233, and a lower swing seat 234. The top of the connecting seat 231 can be connected to the upper swing seat 21, and the bottom of the connecting seat 231 is connected to the top of the middle swing seat 233. The bottom of the middle swing seat 233 is fixedly connected to the lower swing seat 234. The second drive cylinder 232 is set on the lower swing seat 234. A guide rail slider 235 is provided on one side of the connecting pad 238. The guide rail slider 235 is slidably connected to the lower swing seat 234. The drive end of the second drive cylinder 232 can be connected to the connecting pad 238. The edge banding can pass through the connecting pad 238 away from the second drive cylinder 232. When it is necessary to remove or cut the edge banding, the second drive cylinder 232 drives the connecting pad 238 to move to abut or fix the edge banding.

[0065] Optionally, to facilitate the rapid removal of sawing debris, the oscillating unit 23 may include a saw blade connecting plate 236. This plate can be fixed to the side of the connecting pad 238 away from the second drive cylinder 232. The second drive cylinder 232 pushes the saw blade connecting plate 236 closer to and against the edge banding strip via the connecting pad 238. An air nozzle 237 can be provided on the top of the saw blade connecting plate 236 to blow away the debris generated during sawing the edge banding strip.

[0066] Optionally, in order to adjust the amount of glue applied to the edge banding tape, the swing assembly 2 may also include a glue amount adjustment unit 24. The glue amount adjustment unit 24 may be set on a different side of the saw blade 224 from the swing unit 23. The distance between the edge banding tape and the glue application shaft 45 is adjusted by the glue amount adjustment unit 24, thereby adjusting the amount of glue applied to the edge banding tape.

[0067] Optionally, the adhesive amount adjustment unit 24 may include an adjustment cylinder 241, a second pressure block 242, and an edge banding pressure plate 243. The drive end of the adjustment cylinder 241 is connected to the edge banding pressure plate 243. The edge banding, after passing through the swing unit 23, passes between the second pressure block 242 and the edge banding pressure plate 243 and proceeds to the area where the adhesive application shaft 45 is located. By adjusting the cylinder 241 to push the second pressure block 242 closer to or further away from the edge banding pressure plate 243, the degree to which the edge banding is in contact with the adhesive application shaft 45 is changed (i.e., the distance between them is fine-tuned), thereby changing the amount of adhesive applied to the edge banding.

[0068] Optionally, to improve the automation level of edge banding, the edge banding connection assembly 6 includes a measuring unit located below the connecting plate 61. The measuring unit includes an edge banding tape detector 64. The detector emits a trigger signal upon contacting the starting end of the edge banding tape on the board. The edge banding processing center receives this trigger signal, determines the detected starting point of the edge banding tape on the board based on the trigger signal, and calculates the length of the edge banding tape applied to the board based on this starting point. The edge banding tape detector 64 can be positioned below the connecting plate 61 and close to the board to be edge banded. After edge banding, the starting point of the edge banding tape on the board contacts the detector 64, triggering it to emit a trigger signal, achieving accurate detection.

[0069] Optionally, the edge sealing connection assembly 6 may include a secondary pressing roller unit 63 and a primary pressing roller unit 62, which may be disposed at the bottom of the connecting plate 61. By having the secondary pressing roller unit 63 and the primary pressing roller unit 62 adhere to the edge sealing tape on the plate, the bonding effect is improved.

[0070] Optionally, to effectively trigger the edge banding tape detector after it is applied to the board, the edge banding tape detector 64 can be fixed to the bottom of the auxiliary pressing roller unit 63. After the edge banding tape is applied to the board, the edge banding processing center controls the auxiliary pressing roller unit 63 to press against the edge banding tape on the board, thereby driving the edge banding tape detector 64 to approach the starting point of the edge banding tape on the board, causing the edge banding tape detector 64 to generate a trigger signal, thus achieving accurate triggering of the edge banding tape detector 64. The edge banding tape detector 64 may include a swing block 642, a detection driver 643 (which can be a cylinder, linear motor, or other linearly moving object), and a proximity switch 641. One end of the swing block 642 can extend below the proximity switch 641, and the driving end of the detection driver 643 can be connected to the swing block 642 in a transmission manner. After the swing block 642 contacts the starting point of the edge banding tape, the swing block 642 rotates, causing one end of the swing block 642 to move into the detection area of ​​the proximity switch 641, triggering the proximity switch 641 to issue a trigger signal. To prevent the proximity switch 641 from being frequently triggered, the detection driver 643 can lower the swing block 642 after the proximity switch 641 issues a trigger signal. After edge banding is completed, the detection driver 643 can raise the swing block 642 for the next detection. When the board has a special shape (such as a circle or quadrilateral), the edge banding processing center can calculate the required length of edge banding tape for certain areas (such as one or more edges) or the entire board based on its shape. After the edge banding tape detector 64 issues a trigger signal, the edge banding processing center can calculate the length of the used edge banding tape based on the current travel of the edge banding head. Once it is determined that this length corresponds to the pre-calculated edge banding tape length, the cutting unit 22 can be controlled to cut the edge banding tape, thereby achieving precise alignment, reducing gaps, and improving the aesthetics of the edge banding.

[0071] Optionally, the secondary pressing roller unit 63 may include a secondary pressing shaft seat 631, a secondary pressing roller 632, and a bearing. The edge sealing tape detector 64 is connected to the bottom of the secondary pressing roller 632 via the bearing to prevent the edge sealing tape detector 64 from rotating when the secondary pressing roller 632 rotates. The secondary pressing roller 632 is connected to the main pressing roller unit 62 via the secondary pressing shaft seat 631. The secondary pressing roller unit 63 is disposed on the side of the main pressing roller unit 62, and the top of the secondary pressing shaft seat 631 is bent toward the main pressing roller unit 62 for fixed connection.

[0072] Optionally, in actual production, there are often situations where the auxiliary pressing roller unit 63 is not needed (such as when the board is too small and the auxiliary pressing roller 632 cannot contact the board). In order to avoid interference from the auxiliary pressing roller 632, the edge sealing connection assembly 6 may also include an auxiliary pressing roller swing unit 65. The auxiliary pressing roller swing unit 65 may be set on the connecting plate 61 and connected to the main pressing roller unit 62. The auxiliary pressing roller swing unit 65 drives the main pressing roller unit 62 to rotate, thereby driving the auxiliary pressing roller unit 63 to rotate to a position away from the board.

[0073] Optionally, the main pressing wheel unit 62 may include a main pressing wheel 626, a main pressing wheel slide 625, a main pressing wheel slider 624, a main pressing wheel cylinder 623, a second cylinder fixing seat 622, and a secondary pressing wheel support 621. The main pressing wheel 626 can be fixed to the bottom of the main pressing wheel slide 625, and the main pressing wheel slider 624 is fixed to the upper part of the main pressing wheel slide 625. The main pressing wheel cylinder 623 is fixed to one side of the second cylinder fixing seat 622, and the second cylinder fixing seat 622 is slidably connected to the upper side of the main pressing wheel slider 624. The driving end of the main pressing wheel cylinder 623 is fixedly connected to one side of the main pressing wheel slide 625. The upper part of the second cylinder fixing seat 622 is connected to the connecting plate 61 through the secondary pressing wheel support 621, and the secondary pressing wheel support 621 can be drivenly connected to the secondary pressing wheel swing unit 65. The top of the auxiliary pressure shaft seat 631 is fixedly connected to the second cylinder fixing seat 622. The main pressure roller slider 624 moves through the main pressure roller cylinder 623, thereby pushing the main pressure roller 626 to stick to the plate, and then pushing the edge banding tape to stick to the plate, thus improving the bonding effect between the edge banding tape and the plate.
