Description

Technical Field

[0001] The utility model relates to the technical field of glue - coating edge - sealing, in particular to a glue - coating edge - sealing mechanism of an automatic edge - sealer. Background Technique

[0002] The full - automatic linear edge - sealer is mainly used for edge - sealing the plates of panel furniture in a linear manner. Its characteristics are automation, high efficiency, high precision and aesthetics, and it has been widely used in domestic panel furniture production enterprises. During the process of edge - sealing panel furniture, it is necessary to perform glue - coating edge - sealing.

[0003] A glue - coating edge - sealing mechanism of a linear edge - sealer with the publication number of CN211466774U was disclosed in the Chinese patent. The application date was December 28, 2019. In this patented technology, the plate is placed on the conveyor belt. Due to the positioning block, the plate will not easily deflect, thus not affecting its processing. The feeding roller transports the edge - sealing tape on it to the glue - coating device through the guiding roller. Under the action of the glue - coating nozzle on the lower side of the glue - coating device, the edge - sealing tape is coated with glue. Then the conveyor belt transports the plate near the glue - coating nozzle. Due to the setting of the guiding roller and the positioning block, the edge - sealing tape can just contact the side wall of the plate. Then, under the action of the disc and the pressure - belt roller, the edge - sealing tape can be quickly and conveniently sealed to the side wall of the plate, thus completing the edge - sealing work of the plate. The utility model combines the two - step edge - sealing operation of traditional plates into one step, which improves the work efficiency and reduces the workload. However, when the above device is used, when the plate contacts the edge - sealing tape, it will drive the edge - sealing tape to be pulled outwards. When the plate stops moving, the edge - sealing tape will still move outwards by a part due to the inertial force of the drive, and this part will not contact the surface of the plate next time, resulting in waste. Therefore, the inventor provides a glue - coating edge - sealing mechanism of an automatic edge - sealer to solve the problems raised in the above background technique. Summary of the Invention

The inner sides of the two sliding blocks are rotatably connected with the tensioning roller. One side of the sliding block is fixedly connected with a support spring. The other side of the support spring is fixedly connected with the sliding groove; the edge - sealing strip passes between the tensioning roller and the positioning wheel.

[0008] As a further scheme of the present utility model: On the top of the workbench, a moving groove is opened.

[0011] As a further scheme of the present utility model: On the right side of the fixed box, a edge - pressing mechanism is arranged. The edge - pressing mechanism includes a hollow tube.

When the edge of the glued board contacts and adheres to the surface of the edge - sealing strip along with the movement of the supporting plate, the edge - sealing strip moves to drive the rotating rod to rotate. And after the edge - sealing strip is cut off, because the inner edge - sealing strip is tensioned, it will not continue to be pulled outwards due to inertia, avoiding waste, and can prevent wrinkles from being generated at the bonding part between the loose edge - sealing strip and the edge of the board. The cooperation of the above - mentioned structures achieves the tensioning effect on the edge - sealing strip.

[0016] In addition, in the glue - applying and edge - sealing mechanism of the automatic edge - sealer, by clamping the outer end of the edge - sealing strip inside the pressing roller, when the board moves along with the supporting plate, it will contact the surface of the edge - sealing strip, and the contact force drives the extension block to move leftwards to compress the pressing spring. At the same time, the elastic force of the compression spring presses the edge - sealing strip against the surface of the edge of the board through the pressing roller, and drives the edge - sealing strip to move outwards along with the movement of the board. At the same time, it drives the pressing roller to roll and drives the pulled - out edge - sealing strip to move along the inside of the arc - shaped groove, thus achieving the guiding of the edge - sealing strip. When the board contacts the edge - sealing strip, the output end of the cylinder extends to drive the cutting knife to move rightwards, cutting off the redundant edge - sealing strip at the rear end of the board. Then the output end of the cylinder moves leftwards to drive the cutting knife to move leftwards until the front end of the board disengages from the pressing roller, and then the output end of the cylinder extends again to cut off the edge - sealing strip at the front end of the board. The cooperation of the above - mentioned structures achieves the pressing effect after the edge - sealing strip is bonded to the board. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following further details this application in combination with the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0024] As Figure 1 shown, a glue - applying edge - sealing mechanism of an automatic edge - sealing machine includes a workbench 10. A moving groove 11 is opened at the top of the workbench 10. The first threaded rod 12 is rotatably connected to the left and right sides inside the moving groove 11. A support plate 15 is threadedly connected to the first threaded rod 12. Support boards 20 are respectively fixedly connected to the front and rear sides of the top of the workbench 10. A glue - applying mechanism 30 is arranged on the front of the rear support board 20.

[0025] Preferably, a first motor 13 is fixedly installed on the right side of the workbench 10. The output end of the first motor 13 is fixedly connected to the first threaded rod 12. Guiding rods 14 are fixedly connected to the left and right sides inside the moving groove 11. The guiding rods 14 are slidably connected to the support plate 15, so as to achieve the effect of guiding the support plate 15 when it moves.

[0026] During use, place the plate on the top of the support plate 15, and then start the first motor 13 through an external power supply. The output end of the first motor 13 drives the first threaded rod 12 to rotate, thereby driving the support plate 15 to move from left to right, driving the plate to move from left to right. During this process, the glue - applying mechanism 30 applies glue to the rear boundary of the plate.

[0027] Preferably, a set of positioning rollers 21 are arranged at the rear side of the front side support plate 20. After placing the plate on the surface of the support plate 15, push the plate forward so that the front side surface of the plate fits against the positioning rollers 21, thereby achieving the effect of initially positioning the plate. And when the plate moves, it will drive the contacting positioning rollers 21 to roll, thereby achieving the effect of reducing the moving friction of the plate.

[0028] Reference Figure 2 , the gluing mechanism 30 includes a movable groove 301 opened on the left side of the top of the workbench 10. The left and right sides inside the movable groove 301 are jointly rotatably connected with a second threaded rod 303. A movable plate 302 is threadedly connected to the second threaded rod 303. The right side of the movable plate 302 is fixedly connected with a connecting plate 305. The front end of the right side of the connecting plate 305 is rotatably connected with a gluing roller 306 through a mounting bracket; a second motor 304 is fixedly installed on the left side of the workbench 10, and the output end of the second motor 304 is fixedly connected with the second threaded rod 303.

[0029] Preferably, the cross-sectional width of the movable groove 301 is adapted to the side width of the movable plate 302, thereby achieving the effect of guiding the movement of the movable plate 302.

[0030] During use, according to the different widths of the plates, start the second motor 304 through an external power supply. The output end of the second motor 304 drives the second threaded rod 303 to rotate, thereby driving the connecting plate 305 to move left and right, thereby driving the gluing roller 306 to move in the same direction, so that the surface of the gluing roller 306 contacts the boundary of the plate; when the plate moves with the support plate 15, it will drive the boundary of the plate to contact the gluing roller 306, thereby achieving the effect of gluing the plate.

[0031] Reference Figure 2 , 3 , referring to FIGS. 4, a sealing device 40 is arranged at the rear end of the right side of the connecting plate 305. The sealing device 40 includes an openable fixed box 401. A rotating rod 402 is rotatably connected to the bottom side inside the fixed box 401. A sealing strip 403 is spirally wound around the surface of the rotating rod 402; the other end of the sealing strip 403 penetrates out of the fixed box 401 from the front end of the right side of the fixed box 401. A fixed frame 404 is fixedly connected to the lower right corner of the fixed box 401. A positioning wheel 405 is rotatably connected to the inner bottom side of the fixed frame 404. A movable tensioning roller 410 is arranged on the top of the positioning wheel 405.

[0032] Reference Figure 5, sliding grooves 406 are respectively formed on the upper and lower sides inside the fixed frame 404. Guide rods 407 are fixedly connected to the left and right sides inside the sliding grooves 406. Sliding blocks 408 are slidably connected to the guide rods 407. The inner sides of the two sliding blocks 408 are rotatably connected to the tensioning rollers 410. A support spring 409 is fixedly connected to the left side of the sliding block 408. The left side of the support spring 409 is fixedly connected to the sliding groove 406; the edge banding strip 403 passes between the tensioning rollers 410 and the positioning wheel 405.

[0033] During use, the elastic force of the support spring 409 presses the tensioning roller 410 against the surface of the edge banding strip 403 through the sliding block 408, so that the edge banding strip 403 is clamped between the tensioning roller 410 and the positioning wheel 405, thus achieving the tensioning effect on the edge banding strip 403. When the edge of the glued board adheres to the surface of the edge banding strip 403 as the supporting plate 15 moves, the movement of the edge banding strip 403 drives the rotating rod 402 to rotate. And after the edge banding strip 403 is cut off, since the inner edge banding strip 403 is tensioned, it will not continue to be carried outwards with inertia and can prevent the edge banding strip 403 from loosening and generating wrinkles at the bonding part with the edge of the board.

[0034] Reference Figure 4 , a pressing mechanism 50 is arranged on the right side of the fixed box 401. The pressing mechanism 50 includes a hollow tube 501. A pressing spring 502 is fixedly connected inside the hollow tube 501. An extension block 503 is fixedly connected to the right side of the pressing spring 502. A pair of clamping blocks 504 are fixedly connected to the right side of the extension block 503. A pressing roller 505 is rotatably connected to the inner sides of the two clamping blocks 504. An arc-shaped groove (not shown in the figure) is formed on the surface of the pressing roller 505, and the arc-shaped groove is clamped with the left side of the edge banding strip 403.

[0035] Preferably, a cylinder 506 is fixedly connected to the right side of the fixing box 401, and a cutting knife 507 is fixedly connected to the output end of the cylinder 506. When in use, the outer end of the edge banding 403 is clamped inside the pressing roller 505, and when the plate moves with the support plate 15, it will contact the surface of the edge banding 403, and the contact force drives the extension block 503 to move leftward to compress the pressing spring 502, and at the same time, the elastic force of the pressing spring 502 presses the edge banding 403 to the surface of the plate boundary through the pressing roller 505, and drives the edge banding 403 outward with the movement of the plate, and at the same time drives the tensioning roller 410 roller, and drives the edge banding 403 pulled outward to move along the inside of the arc groove, so as to guide the edge banding 403. When the boundary of the plate contacts the edge banding strip 403, the output end of the cylinder 506 extends to drive the cutting knife 507 to move to the right, cutting off the excess edge banding strip 403 at the rear end of the plate, and then the output end of the cylinder 506 moves to the left, driving the cutting knife 507 to move to the left, until the front end of the plate is separated from the pressing roller 505, thereby extending and cutting off the edge banding strip 403 at the front end of the plate again through the output end of the cylinder 506.

[0036] The working principle of the utility model is: the elastic force of the support spring 409 presses the tensioning roller 410 against the surface of the edge banding strip 403 through the sliding block 408, so that the edge banding strip 403 is clamped between the tensioning roller 410 and the positioning wheel 405, thereby achieving the tensioning effect of the edge banding strip 403, and when the boundary of the plate after glue coating is bonded to the surface of the edge banding strip 403 as the support plate 15 moves, the movement of the edge banding strip 403 drives the rotating rod 402 to rotate, and after the edge banding strip 403 is cut off, since the internal edge banding strip 403 is tensioned, it will not continue to be brought out of the edge banding strip 403 due to inertia, and can prevent the edge banding strip 403 from loosening and causing wrinkles at the bonding point with the boundary of the plate.
