Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of edge banding machine, especially relates to an edge banding machine. BACKGROUND

[0002] For the plate needing to be edge banded, because there is a certain corner drop or hole condition in the four end portions of the plate in the pre-milling cutter process of the edge banding machine and the re-cutting process of the electronic saw, the four end portion regions need to be filled with more glue, and the middle portion of the plate edge does not need so much glue. If the glue coating amount on the plate edge is uniformly increased to fill the gap of the four end portions, too much glue will overflow from the middle portion of the plate edge, causing waste. If the glue coating amount is uniformly set according to the need of the middle portion of the plate edge, the end portion of the plate edge will not be able to play a waterproof effect due to the gap, and eventually the plate will swell due to the siphon phenomenon.

[0032] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail with the utility model combining with the drawings and examples.

[0033] The utility model embodiment provides a kind of edge banding machine, which is used to coat glue on the edge of plate.The plate has two plate surfaces opposite to each other, and a peripheral side surface surrounding the two plate surfaces, which is generally formed by cutting, thus exposing the internal wood.The edge banding machine is used to coat glue on the edge surface to encapsulate the exposed wood through the glue and achieve waterproof effect.

[0034] In the following examples, a square plate is taken as an example for description.The edge of the plate is four, i.e., the peripheral side surface includes four edge surfaces connected end to end in a ring shape, each edge surface extends along a straight line, and the two connected edge surfaces are perpendicular to each other.Each edge surface has two end portions and a middle portion, the middle portion is between the two end portions, and the length of the end portion is determined according to the length of the area where the corner or gap appears on the edge surface.

[0035] Please refer to Figure 1 and Figure 2 The edge banding machine includes a glue roller 10, a glue coating channel and a glue door 20.

[0036] The glue roller 10 has a ring-shaped glue coating surface 101, and the glue roller 10 can rotate along its central axis.The glue coating surface 101 can also be opposite to the central axis of the glue roller 10, i.e., the glue coating surface 101 is the peripheral side surface of the glue roller 10, or the glue coating surface 101 can be the end surface of the glue roller 10, as long as it can realize the glue coating action on the edge of the plate through rotation.The rotation of the glue roller 10 can be realized in an electric or manual manner, which is not limited here.It should be noted that the rotation speed of the glue roller 10 also affects the amount of glue on the edge surface of the plate, for example, the faster the rotation speed, the more glue, and the slower the rotation speed, the less glue.

[0037] The glue channel has a glue outlet facing the glue applying surface 101, and is used for conveying glue to the glue applying surface 101 through the glue outlet. The glue can be conveyed to the glue channel from the glue storage cavity through the conveying structure or manually, and then discharged to the glue applying surface 101 through the glue outlet of the glue channel. The glue applying surface 101 rotates with the glue applying roller 10, and can apply glue to the edge surface of the board abutting against the glue applying roller 10 during rotation.

[0038] The glue gate 20 is arranged in the glue channel and is used to control the amount of glue discharged from the glue outlet. The amount of glue discharged from the glue outlet can be controlled by the size of the opening of the glue gate 20. Specifically, the glue gate 20 has a first opening and a second opening, and the first opening is larger than the second opening. Thus, the amount of glue applied to the glue applying surface 101 by the glue gate 20 at the first opening is greater than the amount of glue applied to the glue applying surface 101 by the glue gate 20 at the second opening.

[0039] Please refer to Figures 3 to 5 When in use, the board can be moved horizontally along the normal of the center axis of the glue applying surface 101, and the edge surface of the board abuts against the glue applying surface 101 during movement. When one end of the edge surface of the board abuts against the glue applying surface 101, the glue gate 20 can be switched to the first opening to increase the amount of glue applied to the end of the edge surface of the board, so as to better realize the full coverage of the corner and gap at the end of the edge surface of the board. When the board moves to the middle of the edge surface abutting against the glue applying surface 101, the glue gate 20 can be switched to the second opening to reduce the amount of glue applied to the middle of the edge surface of the board, so as to avoid waste caused by glue overflow. Then, when the board continues to move to the other end of the edge surface abutting against the glue applying surface 101, the glue gate 20 can be switched back to the first opening to increase the amount of glue applied to the end of the edge surface of the board, so as to better realize the full coverage of the corner and gap at the end of the edge surface of the board.

[0040] In this way, the edge banding machine can adjust the amount of glue applied to the edge surface of the board by arranging the glue gate 20 and adjusting the opening of the glue gate 20 according to the moving position of the board, so as to apply glue to the edge surface of the board according to the needs of the glue amount at different positions on the edge surface of the board, thereby improving the applicability of the edge banding machine.

[0041] Please refer to Figure 1 In some embodiments, the edge banding machine further comprises a driving member 30 connected to the glue gate 20 and used to drive the glue gate 20 to switch between the first opening and the second opening. The arrangement of the driving member 30 enables the opening of the glue gate 20 to be switched automatically, thereby saving labor costs.

[0042] In other embodiments, the opening degree of the glue door 20 can also be manually adjusted, so that the opening degree of the glue door 20 can be adjusted by manually observing the position of the plate, and the numerical control parameters of the edge banding machine do not need to be adjusted for different plates. The opening degree of the glue door 20 can also be more than the first opening degree and the second opening degree, and a plurality of levels of opening degrees can be set to adapt to different needs of different positions for the glue application amount. In addition, the opening degree of the glue door 20 can also be gradually changed from the first opening degree to the second opening degree or from the second opening degree to the first opening degree, which is not limited here.

[0043] Optionally, the driving member 30 is a pneumatic cylinder 30a, which can drive the glue door 20 through the reciprocating movement of the piston 32. The cylinder body 31 of the pneumatic cylinder 30a can be fixed in position, and the output end of the piston 32 rod is connected with the glue door 20.

[0044] Please refer to Figures 3 to 5 In some embodiments, the edge banding machine further comprises a controller, which can control the driving member 30 to make the glue door 20 first maintain the first opening degree, then switch to the second opening degree and maintain the second opening degree, and finally switch to the first opening degree and maintain the first opening degree. In this way, the edge banding machine realizes the automatic driving of the driving member 30 through the setting of the controller, without manual intervention, and the control is more accurate and efficient. The controller can control the driving member 30 to increase the glue application amount on the edge surface of the plate first, then reduce it, and then increase it again, so as to adapt to the needs of different positions on the edge surface of the plate for the glue application amount.

[0045] In some embodiments, the edge banding machine further comprises a sensing mechanism for sensing the position of the edge surface of the plate contacted by the glue application surface 101, and the controller can control the glue door 20 to switch between the first opening degree and the second opening degree according to the sensing result of the sensing mechanism. In this way, the controller can know the position of the plate through the sensing of the sensing mechanism, and adaptively adjust the opening degree of the glue door 20 according to the position of the edge surface on which the glue application surface 101 abuts, so as to realize the automatic control of the glue application amount. The sensing method of the sensing mechanism includes but is not limited to photoelectric sensing, infrared sensing, Hall sensing, pressure sensing, etc.

[0046] Optionally, the controller can control the glue door 20 to maintain the first opening degree when the sensing mechanism senses that the glue application surface 101 contacts the end part of the edge surface of the plate, and control the glue door 20 to switch to the second opening degree when the sensing mechanism senses that the glue application surface 101 contacts the middle part of the edge surface of the plate. In this way, the controller can control the driving member 30 to make the glue application amount on the end part of the edge surface of the plate greater than the glue application amount on the middle part of the edge surface of the plate.

[0047] Optionally, the sensing mechanism comprises a travel switch, which is used to start the controller when the plate passes the preset position. When the plate has not yet been transported to the vicinity of the edge banding machine, the controller can be in an off state. When the plate moves towards the glue applying surface 101 and touches the travel switch during the movement, the travel switch starts the controller, the controller is powered on, and the time when the end and middle part of the edge surface of the plate reaches the glue applying surface 101 can be calculated, so that the glue door 20 is switched to the appropriate opening degree at the corresponding time, thereby achieving different glue applying amounts on different positions of the edge surface of the plate.

[0048] Please refer to Figures 3 to 5 For example, the controller controls the driving member 30 to keep the glue door 20 at the first opening degree within 1-2 seconds after the controller is started, controls the driving member 30 to keep the glue door 20 at the second opening degree within 2-4 seconds, and controls the driving member 30 to keep the glue door 20 at the first opening degree within 4-5 seconds. Correspondingly, one end of the edge surface of the plate contacts the glue applying surface 101 within 1-2 seconds, the middle part of the edge surface of the plate contacts the glue applying surface 101 within 2-4 seconds, and the other end of the edge surface of the plate contacts the glue applying surface 101 within 4-5 seconds.

[0049] Please refer to Figure 1 In some embodiments, the edge banding machine further comprises a workbench 40, the glue applying roller 10 is rotationally connected to the workbench 40, and the glue applying channel is connected to the workbench 40. The workbench 40 is used to provide support for the glue applying roller 10 and the glue applying channel, so that the glue applying roller 10 and the glue applying channel form an integral whole, facilitating transportation and use.

[0050] Optionally, the sensing mechanism, the controller and the driving member 30 can also be all arranged on the workbench 40, or at least one of them can be independently arranged, which is not limited herein.

[0051] Optionally, the cylinder body 31 of the air cylinder 30a is connected to the workbench 40, and the connection mode can be direct connection or indirect connection, which is not limited herein.

[0052] Please refer to Figure 1 In some embodiments, the edge banding machine further comprises a mounting cover 50, which is connected to the workbench 40 and covers the glue applying roller 10. The mounting cover 50 forms an opening 501, and the glue applying surface 101 of the glue applying roller 10 is exposed at the opening 501. The mounting cover 50 can protect the glue applying roller 10, so that the glue on the glue applying roller 10 that is not in use is prevented from being applied to other structural members or being adhered to dust or other impurities. The glue applying channel can be formed by surrounding the mounting cover 50.

[0053] Optionally, the edge banding machine further comprises a connecting rod 60 connected to the mounting cover 50 and the cylinder 30a. In this way, the cylinder body 31 of the cylinder 30a is indirectly connected to the workbench 40 through the connecting rod 60. The connecting rod 60 can adapt to the length of the flagpole and fix the position of the cylinder body 31, so that the cylinder 30a can accurately control the glue door 20.

[0054] Please refer to Figure 1 In some embodiments, the edge banding machine further comprises a glue scraping plate 70 connected to the mounting cover 50, and the end of the glue scraping plate 70 abuts against the glue applying surface 101, and the glue applying area of the plate material is located upstream of the glue scraping plate 70. The glue scraping plate 70 can scrape off the glue on the glue applying surface 101 after the glue applying surface 101 finishes applying glue to the edge surface of the plate material, so as to prevent the glue on the glue applying surface 101 from being air-dried and solidified, causing the glue applying roller 10 to become thicker and affecting the glue applying accuracy in the later period.

[0055] The above is only a preferred embodiment of the present application, and only the technical principle of the present application is specifically described. These descriptions are only for explaining the principle of the present application, and cannot be interpreted as limiting the protection scope of the present application in any way.
