Description

Technical Field

[0001] The invention relates to the technical field of laser edge banding machines, and in particular to a laser edge banding machine with a narrow plate edge banding function. Background Art

[0002] Woodworking edge banding machine is one of the commonly used processing equipment in the panel furniture industry. Its function is to fit the edge banding tape on the processing end surface of the board to make the board more beautiful and prevent moisture from entering the board. Traditional EVA conventional edge banding, PUR edge banding, etc. are constantly working towards smaller glue lines, through hardware improvements such as continuous optimization and upgrading of the glue texture of the glue-applying shaft; through upgrading the glue pot injection mechanism, such as selecting a glue pot; through the development of glue materials, such as improving the purity of PUR glue, etc. The purpose is to "slim down" the glue lines in the board edge banding, but given the working principle of the liquid glue-applying mechanism after heating and the principle of glue sticking, no matter how it is upgraded or modified, the glue lines still exist "blatantly".

[0003] The edge sealing process of EVA and PUR, which heats solid glue to a fluid state and then applies the glue to the board through a glue coating mechanism, has poor waterproof performance, requires preheating equipment, is prone to glue blockage, residual glue affects quality, and releases large amounts of formaldehyde and toluene.

[0004] With the development of the times, the public has higher aesthetic and environmental requirements for home furniture, and EVA and PUR edge banding can no longer meet everyone's needs. The special process of laser edge banding does not require the traditional glue coating process, and can truly achieve almost "0" glue line, perfect fit, stronger waterproof performance, no formaldehyde and no benzene, instant startup, and any color change without cleaning the glue pot, etc., which can well meet the public's aesthetic and environmental requirements for home furniture.

DETAILED DESCRIPTION

[0049] like Figure 1-20As shown, a laser edge banding machine with a narrow plate edge banding function comprises a main frame 1, on which a transmission track is installed, and a narrow plate auxiliary feeding mechanism 2 is installed on the right side of the transmission track. The narrow plate auxiliary feeding mechanism 2 is used to assist narrow and long strips of plate to quickly and efficiently enter the laser edge banding machine with a narrow plate edge banding function for edge banding processing. The transmission crawler is installed with an industrial Internet controller and an intelligent industrial touch screen 19, a pre-milling mechanism 3, a plate over-limit detection mechanism 4, a fast pre-melting mechanism 5, a gluing mechanism 6, a laser edge sealing mechanism 7, a servo belt feeding mechanism 8, a seven-wheel servo edge band pressing mechanism 9, a narrow plate fast front and back trimming mechanism 10, a rough trimming mechanism 11, two groups of fine trimming mechanisms 12, two groups of dual-motor tracking mechanisms 13, two groups of scraper mechanisms 14, a flexible scraper mechanism 15, a waxing mechanism 16 and two groups of polishing mechanisms 17 in sequence from right to left; the pre-milling mechanism 3, the gluing mechanism 6, the laser edge sealing mechanism 7, the seven-wheel servo edge band pressing mechanism 9, the narrow plate fast front and back trimming mechanism 10, the rough trimming mechanism 11, two groups of fine trimming mechanisms 12, two groups of dual-motor tracking mechanisms 13 and two groups of scraper mechanisms 14 are respectively installed with a group of narrow plate auxiliary pressing wheel mechanisms 18.

[0050] Among them, the industrial Internet controller and the intelligent industrial touch screen 19 are responsible for the electrical control, logical operation, parameter setting, human-computer interaction, etc. of the laser edge banding machine with narrow plate edge banding function. The pre-milling mechanism 3 re-trims the defects such as veneer cracking and burrs caused by cutting the edge of the plate, thereby improving the edge banding quality of the edge banding tape and the plate. The plate over-limit detection mechanism 4 prevents the plate from tilting and damaging the laser lens due to placement or processing. The fast pre-melting mechanism 5 can melt the EVA glue particles to 130°~150° in advance. When the liquid level sensor in the glue storage tank of the upper glue coating mechanism 6 senses that the glue level is low, the fast pre-melting mechanism 5 will squeeze the pre-melted EVA glue into the glue storage tank of the upper glue coating mechanism 6 and replenish it in time to avoid uneven glue coating due to insufficient melt glue of the upper glue coating mechanism 6. The function of the upper glue coating mechanism 6 is to evenly apply the EVA glue to the plate and then bond it with the edge banding tape. The laser edge banding mechanism 7 includes a laser host 701, a chiller 702 and a laser galvanometer unit, and its function is to melt the edge banding tape containing a reaction layer on the back and then bond it to the plate. There are multiple edge banding guide grooves on the servo tape feeding mechanism 8, and edge banding tapes of different types, specifications and colors can be placed in each guide groove. It can meet the requirements of EVA edge banding or laser edge banding for different edge bands at the same time, and realize one-key switching. The seven-wheel servo edge band pressing mechanism 9 bonds the edge banding tape and the plate together. The narrow plate fast front and rear trimming mechanism 10 can remove the excess edge banding tape at the front and rear ends of the plate. The rough trimming mechanism 11 is equipped with a trimming motor on the upper and lower sides of the plate, which is used to cut and trim the excess edge banding tape on the upper and lower sides of the plate. The two sets of finishing mechanisms 12 perform fine finishing on the edge banding trimmed by the rough trimming mechanism 11, and trim the required fillets or chamfers (different finishing knives can be installed to trim different fillets or chamfers, and the two sets of finishing mechanisms 12 can achieve one-key switching between fillets, chamfers or different fillets). The two sets of dual-motor tracking mechanisms 13 are used to perform fine finishing on the upper front, upper back, lower front and lower back corners of the edge-banded board in turn (the two sets of motor tracking mechanisms 13 can achieve one-key switching between fillets, chamfers or different fillets). The two sets of scraper mechanisms 14 are used to scrape and trim the board trimmed by the finishing mechanism to eliminate knife marks (the two sets of scraper mechanisms 14 are used in conjunction with the two sets of finishing mechanisms 12 to achieve one-key switching between fillets, chamfers or different fillets). The flexible scraper mechanism 15 is used to remove glue from the board, the waxing mechanism 16 is used to wax and polish the board, and the polishing mechanism 17 is used to polish and grind the board.

[0051] The main frame 1 includes a front feed plate 102, on which a transmission track is arranged, and a material support plate 103 is arranged on the rear end surface of the front feed plate 102, and the end surface of the slat 101 is closely attached to the material support plate 103 during the processing;

[0052] The narrow plate auxiliary feeding mechanism 2 comprises a symmetrically mounted guide post fixing seat 201, the guide post fixing seats 201 are connected together by a plurality of symmetrically mounted guide posts 202, and a linear bearing 204 is installed between the sliding seat 203 and the guide post 202. A sliding seat 203 is slidably installed on the guide post 202, a groove is provided on one side of the sliding seat 203, a rotating pin 206 is rotatably installed in the groove, a rotating block 205 is rotatably installed on the rotating pin 206, a supporting plate 207 is installed on the top of the rotating block 205, a positioning rod 209 is installed between the bottom end of the supporting plate 207 and the upper end surface of the sliding seat 203; a buffer pad 210 is installed at the bottom of the positioning rod 209 near the upper end surface of the sliding seat 203. A material placing plate 208 is installed on the side wall of the rotating block 205 , and a slat 101 is placed on the upper end surface of the material placing plate 208 . The side wall of the slat 101 is closely attached to the side wall of the supporting plate 207 .

[0053] When the narrow strip 101 needs edge banding, due to the processing principle of the edge banding machine, when the plate is edge banding, the edge that needs to be processed will be close to the feed support plate 103 to ensure that it is parallel to the direction of the edge banding machine crawler. Otherwise, not only the edge banding quality cannot be guaranteed, but it is also possible that the edge banding process cannot be completed or the equipment is damaged. Since the length-to-width ratio of the narrow strip is very large, when the short side is edge banded, the existing feed guide method of the feed support plate 103 is difficult to ensure that its short side is parallel to the direction of the edge banding machine crawler. It is very likely that the plate will be skewed and the edge banding process cannot be completed or the equipment will be damaged. Therefore, the support plate 207 in the narrow plate auxiliary feeding mechanism 2 is perpendicular to the direction of the edge banding machine crawler track, and the loading plate 208 is horizontal with the front feeding plate 102. The support plate 207 and the loading plate 208 can slide along the direction of the edge banding machine crawler track. When a narrow long plate needs to be edge banded on the short side, the plate is placed on the loading plate 1108, and the long side of the plate is close to the support plate 207, and the short side is close to the feeding support plate 103, and the sliding seat 203 is pushed along the direction of the crawler track. The sliding seat 203 drives the rotating block 205, the support plate 207, the loading plate 208, and the plate 101 to move forward. When the plate 101 enters the conveyor crawler, the plate is released, and the plate 101 is conveyed by the conveyor crawler to the next workstation for processing. While the plate 101 is released, the sliding seat 203 and its rotating block 205, the supporting plate 207, the material placing plate 208 and other parts fixed thereon are brought back to the starting position to wait for the next plate placing cycle.

[0054] The plate over-limit detection mechanism 4 includes a fixed seat 401, on which a rotating pin 402 is installed, and a rotating swing arm 403 is rotatably installed on the rotating pin 402. A hooked spiral tension spring 405 and a limit screw 408 are installed between the right side wall of the rotating swing arm 403 and the fixed seat 401, wherein the hooks at both ends of the hooked spiral tension spring 405 are respectively hooked on the grooves processed on the fixed seat 401 and the rotating swing arm 403. The limit screw 408 is located outside the rotating swing arm 403 after passing through the rotating swing arm 403, and a tightening nut 409 is installed between the rotating swing arm 403 and the limit screw 408. A contact block 404 is installed on the top outer side wall of the rotating swing arm 403, and a fixed plate 406 is installed at the bottom of the fixed seat 401, and a detection switch 407 is installed on the fixed plate 406.

[0055] When the plate 101 is driven forward by the conveyor crawler, when the narrow strip plate is tilted due to placement or processing reasons, the overhang will exceed the set value of 25mm. At this time, the plate will touch the contact block 404 and drive the swing arm 403 to swing to the left. When the swing arm 403 swings to the left to a certain angle (about 15°), it will trigger the detection switch 407 to act. The detection switch 407 feeds back to the control system through an electrical signal to notify the control system that the plate is out of limit. At this time, the control system stops and alarms, and notifies the operator of the plate out of limit through graphic display on the operation screen. After the operator has completed the plate out of limit processing, the plate out of limit alarm just now can be reset.

[0056] The laser edge-sealing mechanism 7 includes a laser host 701, a chiller 702 and a laser galvanometer unit. The laser host 701 is fixedly mounted on the host frame 1 and is electrically connected to the industrial interconnection controller and the intelligent industrial touch screen 19. The power of the high-energy laser beam generated by the laser host can be controlled on the operation interface. The laser host 701 is connected to the laser galvanometer unit by an optical fiber. The laser host 701 mainly generates high-energy lasers, which are transmitted to the laser galvanometer unit by the optical fiber. The laser galvanometer unit mainly calculates and refracts the high-energy laser beam transmitted from the laser host 701 onto the laser-specific edge-sealing tape coated with a reaction layer. The chiller 702 is connected to the laser host 701 and the laser galvanometer unit through pipelines, respectively, and forms a loop to cool the laser host 701 and the laser galvanometer unit respectively.

[0057] The laser galvanometer unit includes a column 703, the left side wall of the column 703 is connected to a sliding block 706 through a linear guide pair, the linear guide pair includes a linear guide 704 fixedly connected to the column 703, and a linear slider 705 fixedly connected to the sliding block 706 is slidably mounted on the linear guide 704. A lifting plate 707 is mounted on the top of the sliding block 706, and a rotating shaft 709 is rotatably mounted inside the lifting plate 707. The top of the rotating shaft 709 is fixedly connected to a connecting plate 708, and the upper end surface of the connecting plate 708 is fixedly connected to a laser scanning galvanometer 710. An adjustment block 1 717 and an adjustment block 2 718 are symmetrically mounted on the outer side wall of the lifting plate 707, and fixing screws 720 are mounted on both the adjustment block 1 717 and the adjustment block 2 718, and the ends of the fixing screws 720 pass through the adjustment block 1 717 and the adjustment block 2 718 and then abut against the connecting plate 708. The upper end surface of the connecting plate 708 is provided with an arc-shaped adjustment groove, in which an angle adjustment screw 721 is installed, and the end of the angle adjustment screw 721 is against the upper end surface of the lifting plate 707. By rotating the position of the connecting plate 708 relative to the lifting plate 707, the installation angle of the laser scanning galvanometer 710 can be adjusted, and the angle of the high-energy laser beam is also adjusted, so that the high-energy laser beam can be just shot on the edge banding 104 on the horizontal plane. After adjustment, the angle adjustment screw 721 and the fixing screw 720 are tightened to achieve fixation.

The nut portion of the ball screw 713 is fixedly connected to a ball screw nut fixing seat 711, and the ball screw nut fixing seat 711 is fixedly connected to the right side wall of the column 703, and a dust cover 719 is provided on the bottom cover of the ball screw nut fixing seat 711 to protect the ball screw 713 under working conditions. The industrial Internet controller and the intelligent industrial touch screen 19 can automatically adjust the upper and lower positions of the laser scanning galvanometer 710 by controlling the servo motor 716, so that the high-energy laser beam just hits the middle part of the edge banding 104 in the initial state. When the edge banding needs to be heated by laser, the high-energy laser beam will scan the entire edge banding 104 up and down, and after it is evenly heated, it will fit evenly with the plate.

[0059] The servo tape feeding mechanism 8 comprises a bottom plate 801, a guide plate 802 is installed on the upper end surface of the bottom plate 801, a plurality of guide grooves are installed on the guide plate 802, a pre-feed tape driving wheel 803 is arranged between every two guide grooves, and pre-feed tape auxiliary wheels 804 which match with the driving wheel 803 are symmetrically installed on the outer sides of the grooves on the left and right sides of the driving wheel 803, and a symmetrically distributed non-return column 806 is installed at the front end of the pre-feed tape driving wheel 803, and a non-return wheel 805 which matches with the non-return column 806 is installed at the front end of the pre-feed tape auxiliary wheel 804, and symmetrically distributed guide columns 807 are installed at both ends of the guide groove.

Fig.19 As shown (this is the prior art and will not be described in detail here).

[0063] Specifically, a plurality of the guide grooves are distributed in an arc shape, and their extension lines converge to a point, where the tape driving wheel 810 and the auxiliary tape driving wheel 813 are located.

[0064] In the initial state, an edge band 104 is placed in each guide groove. If the 6# edge band in the rightmost guide groove needs to be used, the tape feeding auxiliary wheel 804 is driven by the piston of the cylinder 814 to move the 6# edge band against the pre-feed driving wheel 803 and clamp it. At this time, the DC motor installed under the pre-feed driving wheel 803 rotates forward to pass the 6# edge band through the tape feeding driving wheel 810 and the auxiliary tape feeding wheel 813 (such as Fig. 9When the edge banding is waiting for processing, the belt driving wheel sends it out and fits it to the plate. At this time, the piston of the cylinder 814 retreats, clamping the edge band between the non-return wheel 805 and the non-return column 806. The non-return wheel 805 is equipped with a one-way bearing to prevent the edge band from exiting the guide groove under the action of gravity while waiting, affecting the accuracy and stability of the belt feeding. At this point, a pre-feeding belt is completed. If the edge band needs to be switched, the piston of the cylinder 814 moves forward to clamp the edge band between the pre-feed driving wheel 803 and the belt feeding auxiliary wheel 804, the DC motor reverses to withdraw the existing edge band, and the cylinder 814 retreats to clamp the returned edge band; then the required edge band is constructed, and the required edge band is sent to the cutting mechanism 812 according to the steps described above, and an automatic belt switching is completed.

[0065] The action process of the present invention is as follows:

[0066] First, the industrial Internet controller and the intelligent industrial touch screen 19 are responsible for the electrical control, logical operation, parameter setting, human-computer interaction, etc. of the laser edge banding machine with narrow board edge banding function. Since the laser edge banding process does not require cleaning of the glue pot and melting of glue, it can achieve rapid switching of the board and the edge banding tape. At the same time, different types, colors, and widths of laser edge banding tapes will have different up and down scanning frequencies and power sizes of the high-energy laser beam; secondly, according to each formula corresponding to a kind of edge banding tape, set its up and down scanning frequency, power size, board thickness and other parameters; then, when it is necessary to edge band a certain specification of board, select the corresponding formula, the pressure beam 105 will automatically rise to the corresponding height, and the laser scanning galvanometer 710 will also automatically adjust to the appropriate position, so that the high-energy laser beam is just shot at the middle part of the edge banding tape 104 in the initial state; finally, when the laser heating of the edge banding tape is required, the high-energy laser beam will scan the entire edge banding tape up and down and make it evenly heated and evenly bonded to the board.

[0067] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
