[0022] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0023] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] The present utility model provides a board edge banding device.

[0025] Embodiment 1:

[0026] As shown in Figures 1-3 , it includes an edge banding device 1. Positioning sleeves 2 are rotatably connected to both sides of the edge banding device 1. Bearings 11 are fixedly connected to both sides of the edge banding device 1. A rotating shaft 21 is fixedly connected to one side of the positioning sleeve 2. The rotating shaft 21 is rotatably connected to the inside of the edge banding device 1 through the bearing 11. A sliding rod 3 is slidably connected to the inside of the positioning sleeve 2. A support box 4 is fixedly connected to the top of the sliding rod 3. A plurality of roller shafts 5 are rotatably connected to the inside of the support box 4. A plurality of positioning grooves 31 are formed at the bottom of the sliding rod 3. Support rods 12 are fixedly connected to both sides of the front part of the edge banding device 1. A positioning shaft 13 is fixedly connected to the outside of the support rod 12. The positioning shaft 13 is inserted into the positioning groove 31. When the sliding rod 3 is lifted upward, the positioning groove 31 can be disengaged from the surface of the positioning shaft 13. At this time, the sliding rod 3 can be pushed and pulled to adjust the distance between the support box 4 and the edge banding device 1. After the adjustment is completed, the sliding rod 3 is lowered, and the positioning groove 31 below the sliding rod 3 is sleeved on the surface of the positioning shaft 13, so that the sliding rod 3 can be supported and positioned.

[0027] Embodiment 2:

[0028] In the positioning device of the woodworking edge banding machine disclosed in Chinese Patent CN221365142U, the baffle can only position rectangular or parallelogram-shaped plates. However, for trapezoidal plates or other shaped plates with a straight edge on one side and an inclined edge on the opposite side, the baffle cannot be used. To solve this problem, as shown in Figure 3 , on the basis of Embodiment 1, the plurality of roller shafts 5 include a plurality of straight roller shafts 51 and a plurality of inclined roller shafts 52. Bearings are provided in the middle of both the straight roller shafts 41 and the inclined roller shafts 52, and both the straight roller shafts 41 and the inclined roller shafts 52 are rotatably connected to a positioning rod through the bearings. The difference is that the conveying direction of the straight roller shafts 41 is parallel to the conveying direction of the conveyor belt 18, while the positioning rod of the inclined roller shafts 52 fixes the inclined roller shafts 52 obliquely in the support box 4, so that the included angle between the driving direction of the inclined roller shafts 52 and the conveying direction of the conveyor belt 18 is an acute angle. In this way, when the inclined roller shafts 52 convey the plate, a force towards the limiting plate 16 can be applied to the plate, so that the plate can squeeze the edge banding strip on the side, ensuring that the edge banding strip is firmly adhered to the side of the plate. And the plurality of straight roller shafts 51 are divided into two groups, and the two groups of straight roller shafts 51 are respectively located on both sides of the inclined roller shafts 52. As shown in Figure 3As shown in the figure, the position of the inclined roller shaft 52 corresponds to that of the limiting roller group 17 on the limiting seat 15, and the two groups of straight roller shafts 51 are respectively located on both sides of the limiting seat 15, that is, corresponding to the feed inlet and the discharge outlet. After placing the plate above the support box 4 and the workbench 14, when the conveyor belt 18 conveys the plate to move, before the plate enters below the limiting roller group 17, the plate is above the first group of straight roller shafts 51. At this time, the plate only receives the force in the conveying direction of the conveyor belt 18, so that the plate moves along the conveying direction of the conveyor belt 18, ensuring that the plate does not contact the side surface of the limiting seat 15. When the plate enters below the limiting roller group 17, that is, the side surface of the limiting plate 16, a part of the plate moves above the inclined roller shaft 52. At this time, the plate will receive a force towards the limiting plate 16, so that the plate presses the edge banding strip on the side, ensuring the firmness of the edge banding strip pasting. When a part of the plate passes through the limiting roller group 17, the part passing through the limiting roller group 17 is above the second group of straight roller shafts 51. Therefore, the part of the plate passing through the limiting roller shaft 17 will not receive the force towards the limiting plate 16, thus avoiding the problem that the part of the plate tail that does not pass through the limiting roller group 17 rotates around the tail end of the limiting seat 15, resulting in the plate tail detaching from the support of the limiting plate 16.

[0029] Embodiment Three:

[0030] As Figure 3 shown in the figure, on the basis of Embodiment One or Embodiment Two, the support box 4 includes a box body 41 and a box cover 42. The box cover 42 is fixedly installed on the top of the box body 41. A plurality of support grooves 411 are opened on both sides of the top of the box body 41, and a plurality of pressing grooves 421 corresponding to the support grooves 411 are opened on both sides of the bottom of the box cover 42. The roller shaft 5 is placed in the support groove 411 through the positioning rod. Then, after covering the box cover 42 on the top of the box body 41, the pressing groove 421 is sleeved on the surface of the positioning rod of the roller shaft 5, so as to position the roller shaft 5. A plurality of hole grooves 422 are opened on the top of the box cover 42, and the hole grooves 422 enable the roller shaft 5 to protrude above the box cover 42. A plurality of threaded cylinders 412 are fixedly connected inside the box body 41, and a plurality of through holes 423 are opened on the top of the box cover 42. By using bolts to penetrate the through holes 423 and threadedly connect with the threaded cylinders 412, the box cover 42 can be fixed on the box body 41.

[0031] The working principle of the utility model is as follows: when in use, according to the width of the plate, the support box 4 is moved upward to make the positioning sleeve 2 rotate and the positioning groove 31 disengage from the surface of the positioning shaft 13. At this time, the sliding rod 3 can be pulled to adjust the spacing between the support box 4 and the edge banding device 1. After the adjustment is completed, the support box 4 is lowered, and the positioning groove 31 below the sliding rod 3 is sleeved on the surface of the positioning shaft 13, thereby completing the support and fixation of the sliding rod 3, and then the plate is placed on the conveyor belt 18 above the workbench 14, and the roller 5 in the support box 4 supports the bottom of the other side of the plate, and the conveyor belt 18 conveys the plate to the bottom of the limiting roller group 17. After the edge of the plate is coated with glue and the edge banding strip is glued, when the conveyor belt 18 conveys the plate, the inclined roller 52 rolls with the movement of the plate and provides the plate with a thrust in the direction of the limiting plate 16, so that the plate squeezes the edge banding strip to the side of the limiting plate 16, thereby ensuring the firmness of the edge banding strip and the stability of the plate movement.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. When adjusting the sliding rod 3, you only need to move the support box 4 upwards to rotate the positioning sleeve 2 and disengage the positioning groove 31 from the surface of the positioning shaft 13. At this time, you can pull the sliding rod 3 to adjust the distance between the support box 4 and the edge banding device 1. After the adjustment is completed, put down the support box 4, and the positioning groove 31 under the sliding rod 3 is sleeved on the surface of the positioning shaft 13, thereby completing the support and fixation of the sliding rod 3. The operation is simple, saving time and effort.

[0034] 2. By setting the inclined roller 52, the inclined roller 52 supports the plate when conveying the plate, and the inclined roller 52 rotates to provide thrust to the plate during the movement of the plate, so that one side of the plate edge can squeeze the edge banding strip to ensure the firmness of the edge banding strip. This design can be applied to plates of various shapes and has a wide range of applications.

[0035] 3. By setting two groups of straight rollers 51, which are respectively located on both sides of the inclined roller 52, it is possible to avoid the problem that when the plate is fed, the plate is subjected to thrust, causing the plate to conflict with the limit seat 15, affecting the feeding problem; when the plate is discharged, the plate passing through the limit seat 15 is subjected to thrust, causing the part of the plate that has not passed through the limit seat 15 to rotate around the edge of the limit seat 15, causing the plate to detach from the limit plate 16, affecting the firmness of the edge banding, thereby improving reliability.

[0036] 4. The support box 4 consists of a box body 41 and a box cover 42, which are assembled by bolts. When individual or part of the roller shaft 5 is damaged, it is only necessary to remove the box cover 42, and then the damaged roller shaft 5 can be directly taken out for replacement, thereby achieving the purpose of easy maintenance.
