Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and in particular to an adhesive application device for a beveled edge banding machine. Background Technology

[0002] Edge banding is a crucial production step in panel furniture manufacturing. It effectively protects the panels, enhances their appearance, and prevents damage to edges and corners, peeling, or flaking of the veneer during transportation and use. It also provides waterproofing, seals against harmful gases, and reduces deformation. The quality of edge banding directly impacts the product's quality, price, and grade. With the continuous development of edge banding technology, edge banding styles have become increasingly diverse, with beveled or combined bevel-straight edge banding gaining popularity. However, current edge banding production often requires highly skilled operators, significantly limiting production and making it difficult to guarantee quality.

[0003] Currently, there are two main methods for edge banding of boards that combine beveled and straight surfaces:

[0004] (1) It is completed by the oblique edge gluing mechanism and the straight edge gluing mechanism respectively. However, since the two mechanisms work in opposite directions, they occupy a large space in the equipment, have many structural parts, and have high production costs. This is a great test for the personnel who are debugging the equipment. In addition, the oblique and straight surfaces of the board are not glued at the same time. Generally, the straight edge is glued first and then the oblique edge is glued. The glue on the straight edge cools down faster and the bonding effect is not good.

[0005] (2) The adhesive application mechanism is to apply adhesive to the inclined and straight edges of the board by the conical surface of the adhesive application shaft and to apply adhesive to the straight edges of the board by the cylindrical surface of the adhesive application shaft. However, since the diameters of the inclined and straight edges of the integrated adhesive application shaft are inconsistent, the linear velocity is greater the further away from the inclined edge, and the amount of adhesive is also greater. The area of ​​sealing the inclined edge is larger, the amount of adhesive consumed is more, the adhesive line is more obvious, the cost is higher, and the sealing effect is poor. Utility Model Content

[0006] To address the shortcomings of the existing technology, this utility model provides a gluing device for a beveled edge banding machine, which solves the problems of existing beveled edge banding machines being unable to perform gluing operations on both beveled and straight edges simultaneously and having high glue consumption.

[0007] This utility model is achieved using the following technical solution:

[0008] A gluing device for a beveled edge sealing machine includes a gluing mechanism. The gluing mechanism includes a gluing box, a gluing shaft, and a glue quantity adjustment assembly. The gluing box has a gluing groove, and the gluing shaft is rotatably disposed within the gluing groove. The gluing shaft includes an integrally designed straight gluing portion and a beveled gluing portion, at least a portion of which is exposed outside the opening of the gluing groove. The glue quantity adjustment assembly includes a rotating shaft, a scraper fixedly connected to the rotating shaft, and a drive unit for driving the rotating shaft to rotate. The gluing box has a rotating area for the scraper to rotate. The scraper has a vertical end edge that cooperates with the straight gluing portion and a beveled end edge that cooperates with the beveled gluing portion. Gaps for glue to flow are provided between the vertical end edge and the straight gluing portion, and between the beveled end edge and the beveled gluing portion. The size of the gaps can be adjusted by the rotation of the rotating shaft.

[0009] Furthermore, the glue application mechanism also includes a glue guide block. The glue application box is provided with a glue channel, which has an outlet and an inlet. The glue guide block is provided with a glue outlet that connects to the inlet, a glue channel that connects to the outlet, and a main glue channel that connects to the outlet. The main glue channel has two glue switching ports, each connected to a glue guide interface. The glue guide interface is equipped with a glue tube connector, and the glue switching port is equipped with a switching needle valve for sealing the glue guide interface.

[0010] Furthermore, the drive unit includes a connecting rod and a cylinder, one end of the connecting rod is connected to the end of the rotating shaft, and the other end of the connecting rod is connected to the telescopic rod of the cylinder.

[0011] Furthermore, it also includes an up-and-down adjustment mechanism for adjusting the glue application shaft to fit against the inclined surface of the board. The up-and-down adjustment mechanism includes a fixed base and a slide. The fixed base is provided with a guide shaft. The slide is slidably connected to the guide shaft through a bearing so that the slide slides up and down along the guide shaft. The slide is connected to the glue application box through a connecting plate.

[0012] Furthermore, the fixed base is provided with a counter and a counter shaft connected to the counter, one end of the counter shaft being connected to the slide.

[0013] Furthermore, it also includes a floating mechanism for adjusting the adhesive application mechanism to press along the inclined surface of the plate. The floating mechanism includes two locking parts, a long locking block, a short locking block, an adjusting shaft for connecting the two locking parts, the long locking block, and the short locking block, and an adjusting member. The extending direction of the adjusting shaft is perpendicular to the inclined side of the plate. The two locking parts are slidably connected to the adjusting shaft via linear bearings. One end of the adjusting shaft is connected to an adjusting support. One end of the adjusting member moves through the adjusting support and connects to one of the locking parts. The adjusting member pushes the locking part to slide along the extending direction of the adjusting shaft. The other end of the adjusting member is fitted with an elastic element, which is located between the adjusting support and the end of the adjusting member.

[0014] Furthermore, it also includes a rotary fine-tuning mechanism, which includes a first angle adjusting plate and a second angle adjusting plate. The surface of the first angle adjusting plate is provided with an arc-shaped groove, and the second angle adjusting plate is provided with an arc-shaped boss that slides in cooperation with the arc-shaped groove.

[0015] Furthermore, the glue-applying box is equipped with a guide.

[0016] Furthermore, it also includes a photoelectric sensor for detecting the amount of adhesive in the coating tank.

[0017] Furthermore, it also includes an adhesive application drive mechanism for driving the adhesive application shaft to rotate. The adhesive application drive mechanism includes a universal joint connected to the adhesive application shaft, a sprocket connected to the universal joint, and a pressing mechanism for driving the sprocket to rotate.

[0018] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0019] This utility model's glue-applying shaft includes an integrally designed straight-side glue-applying section and an inclined-side glue-applying section, enabling simultaneous application of glue to both sides in one pass. The glue quantity adjustment component significantly reduces glue consumption, improves the appearance quality of the sheet material, lowers production costs, and thus increases production efficiency. Because the scraper has a vertical end edge that mates with the straight-side glue-applying section and an inclined end edge that mates with the inclined-side glue-applying section, it ensures consistent glue quantity on both the inclined and straight sides of the sheet material, improving edge-sealing quality.

[0036] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0037] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0038] like Figures 1 to 15As shown, this utility model provides a glue application device for a beveled edge sealing machine, including a glue application mechanism 10. The glue application mechanism 10 includes a glue application box 11, a glue application shaft 12, and a glue quantity adjustment component 13. The glue application box 11 is provided with a glue application groove 113. The glue application shaft 12 is rotatably disposed within the glue application groove 113. The glue application shaft 12 includes an integrally designed straight glue application part 121 and a beveled glue application part 122. At least a portion of the straight glue application part 121 and the beveled glue application part 122 are exposed outside the opening of the glue application groove 113. The glue quantity adjustment component 13 includes a rotating shaft 131 and is fixedly connected to the rotating shaft 131. The scraper 132 and the drive unit 133 that drives the rotating shaft 131 to rotate are provided. The glue box 11 is provided with a rotating area for the scraper 132 to rotate. The scraper 132 has a vertical end edge 1320 that cooperates with the straight glue application part 121 and an inclined end edge 1321 that cooperates with the inclined glue application part 122. A gap 14 for glue to flow through is left between the vertical end edge 1320 and the straight glue application part 121 and between the inclined end edge 1321 and the inclined glue application part 122. The size of the gap 14 can be adjusted by the rotation of the rotating shaft 131.

[0039] In this embodiment, the glue-applying shaft 12 includes an integrally designed straight glue-applying section 121 and an inclined glue-applying section 122, enabling simultaneous application of glue to both the inclined and straight edges in one operation. The inclined glue-applying section 122 has a glue-applying surface, and its cross-sectional shape is a tapered structure, narrower at the top and wider at the bottom. Since the scraper 132 has a vertical end edge 1320 that mates with the straight glue-applying section 121 and an inclined end edge 1321 that mates with the inclined glue-applying section 122, when the drive mechanism rotates the shaft 131, the scraper 132, along with the shaft 131, causes the vertical end edge 1320 and the inclined end edge 1321 to simultaneously contact (note that they do not actually touch) the straight glue-applying section 121 and the inclined glue-applying section 122 of the glue-applying shaft 12, ensuring consistent glue application on both the inclined and straight edges of the board. There is still a gap 14 between the board 132 and the glue application shaft 12. This gap 14 is used to determine the thickness of the glue applied to the surface of the board. Since the scraper 132 can adjust the size of the gap 14 as the rotating shaft 131 rotates, the larger the gap 14, the thicker the glue layer on the glue application shaft 12, and the smaller the gap 14, the thinner the glue layer on the glue application shaft 12. In this way, the glue layer thickness on the glue application shaft 12 can be adjusted by adjusting the size of the gap 14 to meet different glue application needs. Specifically, when the glue-applying shaft 12 rotates, it draws glue from the glue-applying tank 113 to the straight glue-applying section 121 and the inclined glue-applying section 122. When it is necessary to reduce the amount of glue applied, the drive unit 133 drives the rotating shaft 131 to rotate, and the scraper 132 rotates with the rotating shaft 131, so that the edge of the scraper 132 is more tightly attached to the straight glue-applying section 121 and the inclined glue-applying section 122, thereby reducing the gap 14 between the scraper 132 and the glue-applying shaft 12. This reduces the thickness of the applied adhesive (i.e., reduces the amount of glue applied). Conversely, if it is necessary to increase the thickness of the applied adhesive, the rotating shaft 131 is rotated to increase the gap 14 between the scraper 132 and the glue-applying shaft 12. This can effectively save glue usage, control production costs, and improve edge sealing quality.

[0040] The gluing mechanism 10 of this invention allows for simultaneous gluing of both beveled and straight edges, completing the gluing process for both edges in one operation. It can seal fully beveled or a combination of beveled and straight edges, depending on actual needs. By incorporating the glue quantity adjustment component 13, the amount of glue used is significantly reduced, improving the appearance quality of the boards, lowering production costs, and thus increasing production efficiency.

[0041] It is understood that this utility model can directly replace the straight edge gluing mechanism and the beveled edge gluing mechanism of the original edge banding equipment, so as to realize the two functions of beveled edge gluing and straight edge gluing at the same time. The specific operation method is to first remove the straight edge gluing mechanism and the beveled edge gluing mechanism of the original equipment, and then install the gluing device of this utility model in the position of the beveled edge gluing mechanism of the original edge banding equipment, so as to quickly replace the straight edge mechanism and the beveled edge gluing mechanism of the original edge banding equipment.

[0042] In a preferred embodiment, the glue application mechanism 10 further includes a glue guide block 15. The glue application box 11 is provided with a glue channel 111. The glue channel 111 is provided with a glue outlet 110 and a glue inlet 112. The glue guide block 15 is provided with a glue outlet 150 that is connected to the glue inlet 112, a glue channel 151 that is connected to the glue outlet 150, and a main glue channel 152 that is connected to the glue channel 151. The main glue channel 152 has two glue switching ports 153. Both glue switching ports 153 are connected to glue guide interfaces 154. The glue guide interfaces 154 are provided with glue tube connectors 16. The glue switching ports 153 are provided with switching needle valves 17 for sealing the glue guide interfaces 154.

[0043] In this embodiment, the glue channel 111 of the glue application box 11 is connected to the glue outlet 150 of the glue guide block 15. The glue guide block 15 is provided with a glue tube connector 16. A negative pressure glue delivery device is connected to the glue tube connector 16. The negative pressure glue delivery device delivers the glue through the glue guide block 15 to the glue channel 111 of the glue application box 11. The glue flows from the glue outlet 110 into the glue application tank 113. This eliminates the need to design a glue pot to supply glue to the glue application box 11, thus saving the operation of cleaning the glue pot. In addition, the glue guide block 15 is connected to two glue tube connectors 16 and two switching needle valves 17, which facilitates the switching of different colored glues, greatly improving the glue changing efficiency and meeting the manufacturer's need for quick glue switching in production.

[0044] In a preferred embodiment, the drive unit 133 includes a connecting rod 1331 and a cylinder 1332. One end of the connecting rod 1331 is connected to the end of the rotating shaft 131, and the other end of the connecting rod 1331 is connected to the telescopic rod of the cylinder 1332. In this embodiment, the cylinder 1332 drives the connecting rod 1331 to move, which in turn drives the rotating shaft 131 to rotate, thereby realizing the rotation of the scraper 132. The cylinder 1332 is used to achieve precise rotation of the scraper 132, thereby precisely adjusting the size of the gap 14 and achieving intelligent control of the adhesive quantity. Of course, in other embodiments, the drive unit 133 can also be driven by other motors.

[0045] In a preferred embodiment, the system further includes a vertical adjustment mechanism 20 for adjusting the glue application shaft 12 to fit against the inclined surface of the board. The vertical adjustment mechanism 20 includes a fixed base 21 and a slide 22. The fixed base 21 is provided with a guide shaft 23. The slide 22 is slidably connected to the guide shaft 23 through a bearing so that the slide 22 slides up and down along the guide shaft 23. The slide 22 is connected to the glue application box 11 through a connecting plate 26.

[0046] In this embodiment, the slide 22 drives the glue application mechanism 10 to move up and down along the guide shaft 23 through the connecting plate 26, so that the glue application shaft 12 is in contact with the inclined straight surface of the board; therefore, the up and down adjustment mechanism 20 can make the glue application shaft 12 fit with the inclined straight surface of the board with different thicknesses, thereby improving the glue application quality.

[0047] In a preferred embodiment, the fixed base 21 is provided with a counter 24 and a counter shaft 25 connected to the counter 24, and one end of the counter shaft 25 is connected to the slide 22.

[0048] In this embodiment, the counter 24 displays the vertical lifting distance of the adhesive application mechanism 10. The counter shaft 25 is perpendicular to the platform, and the counter 24 reflects the lifting range of the adhesive application mechanism 10. Therefore, by adjusting the counter 24 according to the thickness of different boards, different thicknesses of boards can be quickly switched. The counter 24 enables visual operation, facilitating rapid switching between boards of different thicknesses and significantly improving efficiency.

[0049] In a preferred embodiment, the system further includes a floating mechanism 30 for adjusting the adhesive application mechanism 10 to press against the inclined surface of the plate. The floating mechanism 30 includes two locking members 31, a long locking block 32, a short locking block 33, an adjusting shaft 34 for connecting the two locking members 31, the long locking block 32, and the short locking block 33, and an adjusting member 36. The extending direction of the adjusting shaft 34 is perpendicular to the inclined side of the plate. The two locking members 31 are slidably connected to the adjusting shaft 34 via linear bearings 38. One end of the adjusting shaft 34 is connected to an adjusting support 35. One end of the adjusting member 36 moves through the adjusting support 35 and connects to one of the locking members 31. The adjusting member 36 pushes the locking member 31 to slide along the extending direction of the adjusting shaft 34. The other end of the adjusting member 36 is fitted with an elastic element 37, which is located between the adjusting support 35 and the end of the adjusting member 36.

[0050] In this embodiment, the two locking members 31 are connected to the fixed base 21 of the up-down adjustment mechanism 20, and the long locking block 32 and the short locking block 33 are fixed on the second angle adjustment plate 42 of the rotary fine-tuning mechanism 40. The locking members 31 are pushed to slide along the extension direction of the adjustment shaft 34 by the adjusting member 36, which in turn drives the glue application mechanism 10 to move along the direction perpendicular to the inclined edge of the board, so that the glue application mechanism 10 can fit more tightly with the board when applying glue, improving the glue application quality. Therefore, by setting the floating mechanism 30, the glue application mechanism 10 can fit more tightly with the board when applying glue, ensuring the quality of the glue application. Specifically, the long locking block 32 acts as a limit, and the elastic element 37 acts as a reset.

[0051] As a preferred embodiment, the system further includes a rotary fine-tuning mechanism 40, which includes a first angle adjusting plate 41 and a second angle adjusting plate 42. The surface of the first angle adjusting plate 41 is provided with an arc-shaped groove 410, and the second angle adjusting plate 42 is provided with an arc-shaped boss 420 that slides in cooperation with the arc-shaped groove 410.

[0052] In this embodiment, the second angle adjusting plate 42 is connected to the glue application mechanism 10, and the first angle adjusting plate 41 is fixed on the conveyor belt support. Two limiting blocks 43 are fixedly attached to the first angle adjusting plate 41 to limit the rotation angle of the second angle adjusting plate 42. The two limiting blocks 43 are respectively fastened to the second angle adjusting plate 42 by adjusting screws 44. When rotating the second angle adjusting plate 42, the adjusting screws 44 are first disengaged from the second angle adjusting plate 42, allowing the second angle adjusting plate 42 to rotate and move along the arc-shaped trajectory of the arc-shaped groove 410. This causes the glue application shaft 12 to contact the inclined and straight surfaces of the board. After fine-tuning the angle, the adjusting screws 44 are then reconnected to the second angle adjusting plate 42, locking the second angle adjusting plate 42 in a preset position. By setting a rotary fine-tuning mechanism 40, the glue application shaft 12 can maintain a more precise relative distance to the moving wooden board during glue application, improving the glue application quality and completing the glue application action quickly.

[0053] In a preferred embodiment, the glue-applying box 11 is equipped with a guide 18.

[0054] In this embodiment, the guide 18 can guide the inclined surface of the plate, so that the inclined surface of the plate fits more closely with the inclined glue application portion 122 of the glue application shaft 12.

[0055] In a preferred embodiment, a photoelectric sensor 19 is also included for detecting the amount of adhesive in the coating tank 113. In this embodiment, the coating box 11 can be connected to the negative pressure adhesive delivery device via the adhesive guide block 15. Therefore, the photoelectric sensor 19 detects the amount of adhesive in the coating tank 113 in real time and sends the detection signal to the negative pressure adhesive delivery device. The negative pressure adhesive delivery device supplies adhesive to the coating box 11 based on the detection signal, achieving intelligent adhesive dispensing. Therefore, the coating device of this invention can achieve adhesive coating without a glue pot, eliminating the need for cleaning the glue pot and other processes, saving adhesive and reducing coating costs. In particular, when using PUR adhesive, there is no need to worry about cleaning the glue pot after a long period of inactivity. With traditional glue pots, if a period of time is to be passed between applications of PUR adhesive, the glue pot must be thoroughly cleaned; otherwise, the PUR adhesive inside will react with water vapor in the air and cannot be used again even after reheating. In this embodiment, the coating box 11 adds only the amount of adhesive needed, which is more convenient.

[0056] In a preferred embodiment, the system further includes an adhesive application drive mechanism 50 for driving the adhesive application shaft 12 to rotate. The adhesive application drive mechanism 50 includes a universal joint 51 connected to the adhesive application shaft 12, a sprocket 52 connected to the universal joint 51, and a pressing mechanism for driving the sprocket 52 to rotate.

[0057] In this embodiment, the glue application box 11 is equipped with an upper cover and a lower support, respectively. Both the upper cover and the lower support are equipped with sealing gaskets and high-temperature bearings to ensure the upper and lower sealing and rotation of the inclined glue application shaft 12. The lower end of the glue application shaft 12 is connected to the sprocket 52 through a universal joint 51. The pressing motor of the pressing mechanism is connected to the chain to drive the rotation of the glue application shaft 12. In this way, the glue application shaft 12 and the pressing mechanism share the same drive motor, which enables multi-directional and multi-angle adjustment, improves motor efficiency, and reduces installation positions.

[0058] The glue application device of this utility model is applied to wood edge banding technology. In the specific process, the glue tube connector 16 is connected to the negative pressure glue delivery device to provide glue to the glue box 11. The glue flows into the glue application tank 113 from the glue outlet 110. The glue application drive mechanism 50 is started to make the glue application shaft 12 rotate. Using the force of rotation, the glue application shaft 12 rolls the glue flowing into the glue application tank 113 onto the surface of the straight glue application part 121 and the inclined glue application part 122. At this time, the edge banding wood is placed at the opening of the glue application tank 113, and the glue application shaft 12 applies glue to the edge of the board by rotating. To better ensure that the straight glue-applying section 121 and the inclined glue-applying section 122 are properly bonded to the edge-banding wood, an up-and-down adjustment mechanism 20, a floating mechanism 30, and a rotary fine-tuning mechanism 40 are provided. These mechanisms allow for a certain degree of adjustment of the glue-applying mechanism 10 in both up-and-down and forward-and-backward motions, ensuring that the straight glue-applying section 121 and the inclined glue-applying section 122 of the glue-applying shaft 12 are always in contact with the wood to apply glue.

[0059] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
