[0038] An edge banding tape conveyor, such as Figures 1 to 11As shown, it includes a tape feeding platform 100, on which a tape feeding guide groove 27 is provided. Along the tape feeding direction of the tape feeding guide groove 27, the tape feeding platform 100 is sequentially provided with an inlet guide assembly 300, an anti-backflow conveyor assembly 400, a confluence guide assembly 500, an active tape feeding assembly 600, and a tape cutting device 700. The edge sealing tape enters the anti-backflow conveyor assembly 400 via the inlet guide assembly 300. The anti-backflow conveyor assembly 400 is used to drive the edge sealing tape to be conveyed unidirectionally forward along the tape feeding guide groove 27 to the confluence guide assembly 500. The confluence guide assembly 500 is used to guide the edge sealing tape to be conveyed to the active tape feeding assembly 600. The active tape feeding assembly 600 is used to send the edge sealing tape into the tape cutting device 700. The tape cutting device 700 is used to cut the edge sealing tape. Specifically, the embodiments of this application are ingeniously designed. During operation, the edge sealing tape enters the feeding guide groove 27 on the feeding platform 100 via the infeed guide component 300. The edge sealing tape sequentially passes through the anti-backflow conveyor component 400, the confluence guide component 500, the active feeding component 600, and the tape cutting device 700. The infeed guide component 300 is used to guide and limit the edge sealing tape, and the anti-backflow conveyor component 400 is used to drive the edge sealing tape forward unidirectionally along the feeding guide groove 27 to the confluence guide component 500, preventing the edge sealing tape from backing up and ensuring stable transmission. Qualitatively, to prevent the edge banding tape from retracting and affecting the edge banding quality, the inlet guide component 500 guides the edge banding tape into the active feeding component 600, and then the active feeding component 600 conveys the edge banding tape to the cutting device 700 for cutting and delivery. This embodiment integrates the feeding platform 100, the inlet guide component 300, the anti-retraction conveying component 400, the inlet guide component 500, the active feeding component 600, and the cutting device 700 to achieve stable and reliable transmission of the edge banding tape, realize non-retraction transmission of the edge banding tape, adapt to the transmission of edge banding tape of multiple specifications, and has high flexibility.

[0039] In this embodiment, the feeding guide assembly 300 includes a feeding guide base 301 and a plurality of feeding guide roller assemblies 302 arranged in a row rotatably at the bottom of the feeding guide base 301. A plurality of height limiting rods 303 are also arranged in a row at intervals on one side of the feeding guide base 301. The height limiting rods 303 are slidably connected to one side of the feeding guide base 301, and each height limiting rod 303 corresponds to each feeding guide roller assembly 302. A plurality of height limiting snap-fit ​​springs 304 are also arranged in a row at intervals on one side of the feeding guide base 301. One end of each height limiting snap-fit ​​spring 304 is detachably connected to one side of the feeding guide base 301, and the other end of each height limiting snap-fit ​​spring 304 is provided with a first snap-fit ​​hole 305. The height limiting rods 303 and the height limiting snap-fit ​​springs 304 correspond one-to-one, and the upper end of each height limiting rod 303 passes through the first snap-fit ​​hole 305. Specifically, each feed guide roller assembly 302 includes two feed guide roller bodies arranged in parallel. The upper end of the feed guide roller body is rotatably connected to the bottom of the feed guide base 301. The outer sealing strip enters the feed guide groove 27 of the feed platform 100 through the gap between the two parallel feed guide roller bodies. The height limit rod 303 is fixed by the elasticity of the height limit clip 304 and the cooperation of the first clip hole 305. Of course, when it is necessary to adjust the height of the height limit rod 303 by sliding it up and down, the height limit clip 304 is moved so that the height limit rod 303 is disengaged from the first clip hole 305, and the height of the height limit rod 303 can be adjusted.

[0040] In this embodiment, the anti-backward conveying assembly 400 includes an anti-backward transmission base 401, an anti-backward transmission drive 402, an anti-backward component, a drive wheel 404 rotatably mounted on the anti-backward transmission base 401, and a rolling wheel 405 rotatably mounted on the anti-backward transmission base 401. The anti-backward transmission drive 402 is mounted on the anti-backward transmission base 401 and is used to drive the drive wheel 404 to rotate. The anti-backward component includes a swing base 406, an anti-backward drive base 407, and a front and rear drive 408. A feed pulley 409 is rotatably mounted at one end of the swing base 406 near the drive wheel 404, and a feed pulley 409 is rotatably mounted at one end of the swing base 406 near the rolling wheel 405. The device includes a one-way auxiliary wheel 410. A first hinge shaft 411 is rotatably mounted at the end of the swing base 406 away from the transmission base. A front and rear drive member 408 is mounted on the anti-backward drive seat 407. The output end of the front and rear drive member 408 is movably connected to the swing base 406. The front and rear drive member 408 drives the swing base 406 to swing, causing the feeding auxiliary wheel 409 to slide against the driving wheel 404 or the one-way auxiliary wheel 410 to slide against the rolling wheel 405. Preferably, the anti-backward transmission drive member 402 is a motor; the front and rear drive member 408 is a cylinder. Of course, the swing base 406 can be rotatably connected to the feeding platform 100 via the first hinge shaft 411.

[0041] Specifically, the edge banding tape used for edge banding the board passes between the rolling wheel 405 and the one-way auxiliary wheel 410, and between the drive wheel 404 and the feed auxiliary wheel 409. When the anti-backward conveying assembly 400 is working, the anti-backward transmission drive 402 drives the drive wheel 404 to rotate. When the cylinder retracts, it drives the swing base 406 to swing, causing the feed auxiliary wheel 409 to slide against the drive wheel 404, clamping the edge banding tape and moving it forward. When the cylinder extends, it drives the swing base 406 to swing, and the feed auxiliary wheel 409 moves away from the drive wheel 404. At this time, the one-way auxiliary wheel 410 abuts against the rolling wheel 405 to clamp the edge banding, preventing the edge banding tape from backing up. This ensures the stability and reliability of the edge banding tape conveying during board edge banding, which is beneficial to improving the quality of board edge banding.

[0042] The swing base 406 is rotatably equipped with a second hinge shaft 412, and the output end of the front and rear drive members 408 is connected to a pull block 416, which is movably connected to the second hinge shaft 412. The anti-reverse drive base 407, located away from the anti-reverse transmission base 401, is rotatably equipped with a third hinge shaft 413. Specifically, this configuration facilitates the swing of the swing base 406 after the output end of the front and rear drive members 408 is connected to the second hinge shaft 412. Simultaneously, the hinged design provides a certain amount of movement space for the front and rear drive members 408, preventing them from locking up and failing to function properly, thus improving reliability and stability. Of course, the drive base can be rotatably connected to the anti-reverse transmission base 401 or an external equipment workbench via the third hinge shaft 413.

[0043] The anti-backward transmission base 401 is further equipped with a guide transmission housing 414. The rolling wheel 405 is located inside the guide transmission housing 414, and the drive wheel 404 is located at the front end of the guide transmission housing 414. Windows 415 are opened on both sides of the guide transmission housing 414, and the windows 415 protrude from both sides of the rolling wheel 405. Specifically, in this configuration, the guide transmission housing 414 can guide the transmission of the edge banding tape. Combined with the windows 415 protruding from both sides of the rolling wheel 405 and the drive wheel 404 being located at the front end of the guide transmission housing 414, it ensures stable transmission of the edge banding tape. The windows 415 protruding from both sides of the rolling wheel 405 are used to cooperate with the unidirectional auxiliary wheel 410 to achieve the anti-backward function.

[0044] The system includes two anti-reverse components 403. These two anti-reverse components 403 are located on opposite sides of the transmission base. The feed rollers 409 of each anti-reverse component 403 are located on opposite sides of the drive roller 404, and the unidirectional rollers 410 of each anti-reverse component 403 are located on opposite sides of the rolling roller 405. Specifically, with two anti-reverse components 403, two sets of edge banding tape can be fed from opposite sides of a single drive roller 404, which improves the efficiency of edge banding processing.

[0045] In this embodiment, the active belt feeding assembly 600 includes an active belt feeding base 601, an active belt feeding drive 602, an active belt feeding wheel 603, a driven belt feeding wheel 604, a driven belt feeding seat 605, and a driven belt feeding drive 606. The active belt feeding base 601 is mounted on the belt feeding platform 100, the active belt feeding drive 602 is mounted on the bottom of the active belt feeding base 601, and the active belt feeding wheel 603 is rotatably mounted on the active belt feeding base 601. The active belt feeding drive 602 is used to drive... The active feed roller 603 rotates, and the driven feed roller 604 is rotatably mounted on the driven feed seat 605. The driven feed roller 604 is located on one side of the active feed roller 603. The driven feed seat 605 is slidably mounted on the feed platform 100. The driven feed drive 606 is mounted on the feed platform 100 and is used to drive the driven feed seat 605 to move back and forth. The active feed drive 602 is a motor, and the driven feed drive 606 is a cylinder. Specifically, under the above configuration, when it is necessary to move the edge sealing tape forward into the tape cutting device 700, the active tape feeding drive 602 drives the active tape feeding wheel 603 to rotate, and the driven tape feeding drive 606 drives the tape feeding driven seat 605 to move forward and approach the active tape feeding base 601, so that the driven tape feeding wheel 604 approaches and slides against the active tape feeding wheel 603, and the edge sealing tape passes between the active tape feeding wheel 603 and the driven tape feeding wheel 604. Through the rotation of the active tape feeding wheel 603, the edge sealing tape is moved forward and fed into the tape cutting device 700.

[0046] In this embodiment, the tape cutting device 700 includes a tape cutting drive 701, a tape cutting drive base 702, a main blade 703, a tape cutting guide plate 704, a blade assembly 705, and an angle adjustment mechanism. The blade assembly 705 is mounted on the front end of the tape cutting guide plate 704. The main blade 703 is slidably disposed on one side of the tape cutting guide plate 704, with the front end of the main blade 703 directly facing the blade of the blade assembly 705. An inlet 706 for the sealing tape to enter is formed between the blade assembly 705 and the front end of the tape cutting guide plate 704. The front end of the tape cutting drive base 702 is fixedly connected to the tape cutting guide plate 704. The tape cutting drive 701 is mounted on the tape cutting drive base 702 and is used to drive the main blade 703 to move back and forth. A rotating base 707 is provided on the other side of the cutting guide plate 704, and a rotating rod 708 is rotatably disposed within the rotating base 707; the angle adjustment mechanism includes an angle adjusting seat 709, a tightening screw 710 threadedly connected to the angle adjusting seat 709, and a locking screw 711 threadedly connected to the angle adjusting seat 709. The front end of the locking screw 711 is movably connected to the cutting guide plate 704, and a reset elastic element 712 is sleeved on the outer periphery of the locking screw 711. The two ends of the reset elastic element 712 are respectively connected to the cutting guide plate 704 and the angle adjusting seat 709, and the front end of the tightening screw abuts against one side of the cutting guide plate 704; wherein, the rotating rod 708 is rotatably disposed on the external worktable, and the angle adjusting seat 709 is fixed on the external worktable.

[0047] Specifically, in the operation of the tape cutting device 700 of this application embodiment, the edge banding tape is input from the tape inlet 706, passing between the front end of the main blade 703 and the blade edge of the blade attachment 705. The tape cutting guide plate 704 guides the main blade 703 to move, and the tape cutting drive member 701 drives the main blade 703 to move forward along the guide plate 704 and approach the blade edge of the blade attachment 705 to cut the edge banding tape. The tape cutting guide plate 704 can rotate under the action of the rotating rod 708, which can synchronously drive the drive base and the tape cutting guide plate 704 to swing synchronously. In this configuration, since the edge banding tape is constantly moving from the tape inlet 706 in the feeding direction, during tape cutting, the edge banding tape is still moving forward under the drive of the sheet material. Therefore, the cutting guide plate 704 and the main blade 703 are subjected to a forward force. In order to counteract the tension of the sealing tape, an elastic reset member is provided. Under the action of the elastic reset member, the guide plate 704 is pulled back to its original position, thereby avoiding the situation of glue scraping caused by the tension of the cutting tape, ensuring that the cutting tape will not create a glue-free area, and ensuring the quality of the sealing tape. In addition, in this embodiment, a tightening screw 710 is designed. With this setting, the angle of the guide plate 704 can be adjusted, thereby adjusting the orientation of the main blade 703, realizing the adjustment of the cutting tape angle, which can adapt to various cutting tape requirements. By tightening the guide plate 704 with the tightening screw 710, the orientation angle is kept unchanged, which is beneficial to improving the accuracy and reliability of the cutting tape.

[0048] The slicing guide plate 704 has a slicing guide groove 713 on one side, and the main blade 703 is slidably disposed within the slicing guide groove 713. Specifically, this arrangement ensures the stability and reliability of the movement of the main blade 703.

[0049] A bearing 714 is provided between the rotating rod 708 and the rotating base 707. Specifically, this arrangement enables the oscillation of the cutting guide plate 704, improving the stability and smoothness of the oscillation.

[0050] The other front end of the tape cutting guide plate 704 is detachably connected to a shielding member 715, which is used to shield the tape inlet 706. The shielding member 715 has a through hole 716 at its upper end, and a second connecting hole is provided at the upper front end of the tape cutting guide plate 704. A bolt 717 is detachably connected to the second connecting hole, which corresponds to the through hole 716. The bolt 717 is used to lock the shielding member 715 onto the tape cutting guide plate 704. Specifically, this configuration facilitates the assembly and disassembly of the shielding member 715, making it easy to replace and adjust its position to shield or allow space for the tape inlet 706. When the tape inlet 706 is shielded, it prevents the sealing edge from being pulled in, thus preventing accidental tape feeding and providing a safety function.

[0051] In this embodiment, an upper guide limiting component 900 is provided between the anti-backward conveying component 400 and the inlet guide component 500. The upper guide limiting component 900 includes an upper guide limiting seat 901 and a row of upper guide limiting rods 902 spaced apart from the guide limiting seat. The lower end of the upper guide limiting rod 902 is provided with an upper guide groove 903. Specifically, in this configuration, the upper guide groove 903 is correspondingly provided with the tape feeding guide groove 27, and the upper guide groove 903 is located directly above the tape feeding guide groove 27. With the cooperation of the upper guide groove 903 and the tape feeding guide groove 27, the directional feeding of the sealing tape is realized. Furthermore, the upper end of the upper guide limiting rod 902 is slidably disposed on the upper guide limiting seat 901. The upper guide limiting seat 901 is provided with a row of upper guide snap-fit ​​springs 904 spaced apart. One end of the upper guide snap-fit ​​spring 904 is connected to the upper guide limiting seat 901. One side of the upper guide snap-fit ​​spring 904 is detachably connected, and the other end of the upper guide snap-fit ​​spring 904 is provided with a second snap-fit ​​hole. The upper end of the upper guide limiting rod 902 passes through the second snap-fit ​​hole. The upper guide limiting rod 902 is fixed by the elastic force of the upper guide snap-fit ​​spring 904 and the cooperation of the second snap-fit ​​hole. Of course, when it is necessary to slide up and down to adjust the height of the upper guide limiting rod 902, the upper guide snap-fit ​​spring 904 is moved to disengage the upper guide limiting rod 902 from the snap-fit ​​of the second snap-fit ​​hole, and the height of the upper guide limiting rod 902 can be adjusted.

[0052] In this embodiment, the inlet guide assembly 500 includes a first inlet guide plate 501, a second inlet guide plate 502, and an inlet height limiting plate 503. The first inlet guide plate 501 and the second inlet guide plate 502 are arranged in a V-shape. An inlet-outlet gap is formed between one end of the first inlet guide plate 501 and one end of the second inlet guide plate 502. An edge band inlet is formed between the other end of the first inlet guide plate 501 and the other end of the second inlet guide plate 502. The inlet height limiting plate 503 is horizontally disposed within the edge band inlet. An inlet height limiting adjustment block 504 is provided at the upper end of the inlet height limiting plate 503. The inlet height limiting adjustment block 504 is provided with a plurality of first connecting holes 505. Specifically, under the above configuration, the edge banding tape enters the inlet guide component 500 after passing through the upper guide limiting component 900. The edge banding tape enters from the edge banding tape inlet and then enters the active tape feeding component 600 through the inlet-outlet gap, so that the active tape feeding component 600 can transmit the edge banding tape forward. The first inlet guide plate 501 and the second inlet guide plate 502 guide and transmit the edge banding tape. Furthermore, the height of the inlet height limiting plate 503 can be adjusted to accommodate different edge banding tape heights.

[0053] In this embodiment, the edge banding conveyor mechanism further includes an outlet height limiting component 800. The outlet height limiting component 800 includes an outlet height limiting plate, a lifting plate 802, and a lifting adjustment component. The lifting adjustment component includes a lifting adjustment base 803 and a lifting adjustment screw 804 rotatably disposed on the lifting adjustment base 803. The lifting adjustment base 803 is also provided with a lifting guide rod 805, which slides through the lifting plate 802. The lifting adjustment screw 804 is threaded through one end of the lifting plate 802. The lifting plate 802 is L-shaped. The other end of the lifting plate 802 is also equipped with a limiting connecting rod 806. The lower end of the limiting connecting rod 806 is equipped with an outlet limiting guide plate 801, which is correspondingly disposed with the inlet 706. When the edge banding enters from the inlet 706 and is then exited, it is discharged through the outlet limiting guide plate 801.

[0054] Furthermore, the inlet height limiting adjustment block 504 of the inlet guide assembly 500 is connected to the lifting plate 802 through the cooperation of the first connecting hole 505 and the external screw, so that the height of the inlet height limiting plate 503 can be adjusted simultaneously while adjusting the height of the guide plate 801 with the limit.

[0055] In this embodiment, the tape feeding guide groove 27 and related components can be configured in multiple ways, thus enabling this embodiment to be configured as a multi-path tape feeding structure. In one operation, only one path is used, while the others are used as backups. Since the edge sealing process is very fast, the amount of edge sealing tape used is quite large. When the edge sealing tape in one path is used up, the system can immediately switch to the edge sealing tape in other paths, thereby enabling continuous tape feeding without stopping the machine (workers can replenish the edge sealing tape in the paths where it has been used up), thereby improving efficiency and reducing the labor intensity of workers.

[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
