Abstract
Description
Technical Field
[0001] This utility model relates to a glue application path adjustment device for a glue application machine, belonging to the field of glue application technology. Background Technology
[0002] Laminated boards are a type of wood-based engineered wood product. The layers are bonded together with adhesive. The boards are placed on a support platform inside the frame of a laminating machine. After the lower layer is in place, the laminating machine sprays or applies wood laminating adhesive to the surface of the board. Then, the upper layer is placed on the glued lower layer, and the surface of the upper layer is sprayed or applied adhesive again. This process continues until the required thickness is achieved. After the spraying or applying of adhesive is complete, the boards can be sent to a press, where the bonding process is completed by pressing.
[0003] Existing glue-applying machines have multiple glue-applying heads. Each layer of board is coated with glue by the horizontal movement of the glue-applying heads. Due to structural factors such as the glue-applying housing, there will inevitably be a certain gap between adjacent glue-applying heads, resulting in a certain gap between the glue lines sprayed on the board surface. Even if the glue-applying head sprays glue again on the return trip, it only thickens the original glue lines and does not fill the gaps between adjacent glue lines. Areas without glue spraying are prone to poor bonding between boards in the subsequent bonding process. If the poorly bonded area happens to be the sawing position of the board in the later stage, it will also affect the assembly and use of the board and the service life of the board. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing a glue application path adjustment device for a glue application machine.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a glue application path adjustment device for a glue application machine, the glue application machine including a glue application frame and a plurality of glue application components for glue application, the glue application component including a glue application nozzle and a glue application path adjustment mechanism for adjusting the position of the glue application nozzle, a glue application mounting plate is hinged on the glue application frame, the plurality of glue application components are all disposed on the glue application mounting plate, and the glue application mounting plate can swing left and right under the action of the glue application path adjustment mechanism.
[0006] The beneficial effects of this utility model are as follows: the position of the glue-spraying nozzles of the glue-spraying assembly can be adjusted by the glue-spraying path adjustment mechanism. To facilitate the adjustment of the position of the glue-spraying nozzles of multiple glue-spraying assemblies, multiple glue-spraying assemblies are mounted on the glue-spraying mounting plate, which is hinged to the glue-spraying frame. Thus, the glue-spraying path adjustment mechanism can adjust the position of multiple glue-spraying nozzles by driving the glue-spraying mounting plate to swing left and right, thereby adjusting the position of the glue line. For example, when returning after the initial glue application, the glue-spraying path adjustment mechanism can be activated, and the glue-spraying mounting plate can swing left or right. The position of the glue-spraying nozzles can swing left or right, moving the returning glue line between the initial adjacent glue lines. This can fill the gap between the initial adjacent glue lines, thereby improving the bonding quality between adjacent boards. Of course, under the action of the glue-spraying path adjustment mechanism, the glue-spraying mounting plate can also swing left and right. The left and right swing of the glue-spraying nozzles can form a wavy glue line, which can also fill the gap between the initial adjacent glue lines, thereby improving the bonding quality between adjacent boards.
[0007] Based on the above technical solution, the present invention can be further improved as follows.
[0008] Furthermore, the adhesive-coated mounting plate is hinged to the adhesive-coated frame via a connecting mechanism.
[0009] The advantage of adopting the above-mentioned further solution is that the hinge requirements between the glue-coating mounting plate and the glue-coating frame can be met through the connecting mechanism.
[0010] Furthermore, the connecting mechanism includes a hinged connecting block, a first hinge seat disposed on the glue-coating mounting plate, and a second hinge seat disposed on the glue-coating frame. The first hinge seat is connected to one end of the hinged connecting block via a first hinge shaft, and the second hinge seat is connected to the other end of the hinged connecting block via a second hinge shaft.
[0011] The beneficial effect of adopting the above-mentioned further solution is that the connecting mechanism not only realizes the hinge between the glue-spraying mounting plate and the glue-spraying frame, but also reserves sufficient movement space for the glue-spraying nozzle position adjustment of the glue-spraying assembly. Under the action of the glue-spraying path adjustment mechanism, the glue-spraying mounting plate can swing relative to the glue-spraying frame, thus realizing the movement drive of the glue-spraying mounting plate.
[0012] Furthermore, the adhesive application path adjustment mechanism includes an adjustment drive cylinder, the cylinder body of which is connected to the adhesive application frame, and the piston rod of which can drive the adhesive application mounting plate to swing left and right.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the movement control of the glue-spraying mounting plate can be directly achieved by adjusting the drive cylinder. By adjusting the extension and retraction of the piston of the drive cylinder, the movement drive of the glue-spraying mounting plate is achieved, so that the glue-spraying mounting plate can swing relative to the glue-spraying frame, thereby adjusting the glue-spraying path of the glue-spraying nozzle of the glue-spraying assembly. If the glue-spraying path is a straight line, the position of the glue-spraying mounting plate can be adjusted by adjusting the extension or retraction of the drive cylinder, so that the return glue-spraying path of the glue-spraying assembly can be moved to the initial glue-spraying path. Of course, the glue-spraying mounting plate can also be made to swing continuously to form a wavy glue-spraying path.
[0014] Furthermore, the adhesive application path adjustment mechanism includes an eccentric bearing and a drive motor for driving the eccentric bearing to rotate. The drive motor is mounted on the adhesive application frame, and the output shaft of the drive motor is connected to the eccentric bearing. The outer ring of the eccentric bearing can drive the adhesive application mounting plate to swing left and right through a drive rod.
[0015] The beneficial effect of adopting the above-mentioned further solution is that the eccentric bearing is driven by the drive motor to drive the glue-coating mounting plate, so that the glue-coating mounting plate can swing relative to the glue-coating frame, thereby adjusting the position of the glue-coating mounting plate and thus adjusting the glue-coating path of the glue-coating assembly.
[0016] Furthermore, the drive motor is connected to the eccentric bearing via a transmission mechanism.
[0017] The advantage of adopting the above-mentioned further solution is that the drive motor can directly drive the eccentric bearing, or the power can be transmitted to the eccentric bearing through the transmission mechanism. The specific choice can be made according to the actual installation space and subsequent maintenance requirements.
[0018] Furthermore, the transmission mechanism includes a transmission shaft, a driving wheel, a driven wheel, and a transmission belt surrounding the driving wheel and the driven wheel. The transmission shaft is rotatably mounted inside a bushing, which is mounted on the glue-coating frame. The driving wheel is mounted on the output shaft of the drive motor. The driven wheel is mounted on one end of the transmission shaft, and the other end of the transmission shaft is connected to the eccentric bearing.
[0019] Furthermore, the glue coating machine also includes a frame and a glue coating beam. The glue coating beam can move on the frame via a glue coating traveling mechanism, and the glue coating frame is mounted on the glue coating beam via a glue coating lifting mechanism.
[0020] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the glue-spraying walking mechanism, the glue-spraying beam can move on the frame, thereby realizing the glue-spraying operation of the glue-spraying component on the surface of the board. A glue-spraying lifting mechanism is also provided, which can adjust the height of the glue-spraying frame to meet the glue-spraying requirements of boards with different layer heights.
[0021] Furthermore, the adhesive coating traveling mechanism includes a traveling gear, a rack that meshes with the traveling gear, and a traveling motor for driving the traveling gear to rotate. The traveling motor is mounted on the adhesive coating crossbeam, the traveling gear is mounted on the output shaft of the traveling motor, and the rack is mounted on the frame.
[0022] The beneficial effect of adopting the above-mentioned further solution is that the walking motor drives the walking gear to rotate, the rack is fixed on the side of the frame, the walking gear meshes with the rack, and the gluing beam moves on the frame as the gear rotates, and the gluing assembly moves to realize the gluing operation of the board.
[0023] Furthermore, the adhesive application lifting mechanism includes a sleeve, a lifting screw rotatably disposed within the sleeve, and a screw sleeve threadedly connected to the lifting screw. The lifting screw can rotate under the action of a power mechanism. The sleeve is disposed on the adhesive application beam, the screw sleeve is connected to the adhesive application frame, the power mechanism is disposed on the adhesive application beam, and the lifting screw is connected to the output end of the power mechanism.
[0024] The beneficial effect of adopting the above-mentioned further solution is that when the power mechanism is activated, the lifting screw rotates, the screw sleeve can move along the axial direction of the lifting screw, and the glue-spraying frame connected to the screw sleeve can move up and down to adjust the height of the glue-spraying assembly, thereby realizing the adjustment of the glue-spraying height of the glue-spraying nozzle.

[0033] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.
[0034] Example 1, as Figures 1-5 As shown, a glue-spraying path adjustment device for a glue-spraying machine is disclosed. The glue-spraying machine includes a glue-spraying frame 1 and a plurality of glue-spraying components 2 for glue spraying. Each glue-spraying component 2 includes a glue-spraying nozzle and a glue-spraying path adjustment mechanism for adjusting the position of the glue-spraying nozzle. A glue-spraying mounting plate 3 is hinged to the glue-spraying frame 1, and the plurality of glue-spraying components 2 are all disposed on the glue-spraying mounting plate 3. Under the action of the glue-spraying path adjustment mechanism, the glue-spraying mounting plate 3 can swing left and right.
[0035] The adhesive-coated mounting plate 3 is hinged to the adhesive-coated frame 1 via a connecting mechanism. The connecting mechanism satisfies the hinged connection requirements between the adhesive-coated mounting plate 3 and the adhesive-coated frame 1.
[0036] The connecting mechanism includes a hinged connecting block 4, a first hinge seat 5 disposed on the glue-spraying mounting plate 3, and a second hinge seat 7 disposed on the glue-spraying frame 1. The first hinge seat 5 is connected to one end of the hinged connecting block 4 via a first hinge shaft 6, and the second hinge seat 7 is connected to the other end of the hinged connecting block 4 via a second hinge shaft 8. The connecting mechanism not only achieves the hinge between the glue-spraying mounting plate 3 and the glue-spraying frame 1, but also provides sufficient space for adjusting the position of the glue-spraying nozzle of the glue-spraying assembly 2. Under the action of the glue-spraying path adjustment mechanism, the glue-spraying mounting plate 3 can swing relative to the glue-spraying frame 1, thus enabling the movement of the glue-spraying mounting plate 3.
[0037] The glue application path adjustment mechanism includes an adjustment drive cylinder 9. The cylinder body of the adjustment drive cylinder 9 is connected to the glue application frame 1 via a cylinder body mounting plate 10. The piston rod of the adjustment drive cylinder 9 can drive the glue application mounting plate 3 to swing left and right. The piston rod of the adjustment drive cylinder 9 can be hinged to the glue application mounting plate 3 or to the first hinge shaft 6. The movement control of the glue application mounting plate 3 can be directly achieved through the adjustment drive cylinder 9. By adjusting the extension and retraction of the piston of the adjustment drive cylinder 9, the movement drive of the glue application mounting plate 3 is achieved, so that the glue application mounting plate 3 can swing relative to the glue application frame 1, thereby adjusting the glue application path of the glue application nozzle of the glue application assembly 2. If the glue application path is a straight line, the position of the glue application mounting plate 3 can be adjusted by extending or retracting the adjustment drive cylinder 9, so that the return glue application path of the glue application assembly 2 can be moved between the initial glue application path. Of course, the glue application mounting plate 3 can also be continuously swinging to form a wavy glue application path.
[0038] The glue-applying machine also includes a frame 12 and a glue-applying crossbeam 11. The glue-applying crossbeam 11 can move on the frame 12 via a glue-applying traveling mechanism. The glue-applying frame 1 is mounted on the glue-applying crossbeam 11 via a glue-applying lifting mechanism. Under the action of the glue-applying traveling mechanism, the glue-applying crossbeam 11 can move on the frame 12, thereby realizing the glue-applying operation of the glue-applying component 2 on the surface of the board. A glue-applying lifting mechanism is also provided, which can adjust the height of the glue-applying frame 1 to meet the glue-applying requirements of boards with different layer heights.
[0039] The adhesive coating traveling mechanism includes a traveling gear 13, a rack 14 that meshes with the traveling gear 13, and a traveling motor for driving the traveling gear 13 to rotate. The traveling motor is mounted on the adhesive coating beam 11, the traveling gear 13 is mounted on the output shaft of the traveling motor, and the rack 14 is mounted on the frame 12. The traveling motor drives the traveling gear 13 to rotate, and the rack 14 is fixed to the side of the frame 12. The traveling gear 13 meshes with the rack 14, and as the gear rotates, the adhesive coating beam 11 moves on the frame 12. The movement of the adhesive coating assembly 2 enables the adhesive coating operation on the sheet material.
[0040] The adhesive application lifting mechanism includes a sleeve 15, a lifting screw 16 rotatably disposed within the sleeve 15, and a screw sleeve 17 threadedly connected to the lifting screw 16. The lifting screw 16 can rotate under the action of a power mechanism. The sleeve 15 is mounted on the adhesive application beam 11. The screw sleeve 17 is connected to the adhesive application frame 1. The power mechanism is mounted on the adhesive application beam 11, and the lifting screw 16 is connected to the output end of the power mechanism. When the power mechanism is activated, the lifting screw 16 rotates, and the screw sleeve 17 can move along the axial direction of the lifting screw 16. The adhesive application frame 1 connected to the screw sleeve 17 can then move up and down, adjusting the height of the adhesive application assembly 2, thereby adjusting the adhesive application height of the adhesive application nozzle.
[0041] The coating frame 1 is provided with a rod hole through which the lifting screw 16 passes.
[0042] The adhesive coating lifting mechanism has two sets. The power mechanism includes a lifting motor 18, a lifting shaft 19, a main bevel gear, and a driven bevel gear meshing with the main bevel gear. The lifting motor 18 is mounted on the adhesive coating beam 11, the lifting shaft 19 is rotatably mounted on the adhesive coating beam 11, the main bevel gear is mounted on the lifting shaft 19, and the driven bevel gear is mounted on the lifting screw 16. Synchronous lifting drive for both sets of adhesive coating lifting mechanisms can be achieved through a single lifting motor 18.
[0043] Example 2, as Figure 6 and Figure 7 As shown, the adhesive application path adjustment mechanism includes an eccentric bearing 20 and a drive motor 21 for driving the eccentric bearing 20 to rotate. The drive motor 21 is mounted on the adhesive application frame 1, and the output shaft of the drive motor 21 is connected to the eccentric bearing 20. The outer ring of the eccentric bearing 20 can drive the adhesive application mounting plate 3 to swing left and right via a drive rod. The output shaft of the drive motor is connected to the eccentric bearing shaft of the eccentric bearing 20 to drive the eccentric bearing to rotate. One end of the drive rod is hinged to the first hinge shaft 6, and the other end is provided with a bearing bush that matches the outer ring of the eccentric bearing 20. By driving the eccentric bearing 20 through the drive motor 21, the adhesive application mounting plate 3 is driven, allowing the adhesive application mounting plate 3 to swing left and right relative to the adhesive application frame 1, thereby adjusting the left and right position of the adhesive application mounting plate 3 and thus adjusting the adhesive application path of the adhesive application assembly 2.
[0044] The drive motor 21 is connected to the eccentric bearing 20 via a transmission mechanism. The drive motor 21 can directly drive the eccentric bearing 20, or it can transmit power to the eccentric bearing 20 through the transmission mechanism. This allows the impact force generated by the swinging of the adhesive-coated mounting plate 3 to be buffered and absorbed by the transmission mechanism, reducing direct impact and damage to the motor shaft of the drive motor 21. The specific choice can be made based on the actual installation space and subsequent maintenance requirements.
[0045] The transmission mechanism includes a transmission shaft, a driving wheel 22, a driven wheel 23, and a transmission belt surrounding the driving wheel 22 and the driven wheel 23. The transmission shaft is rotatably mounted inside a bushing, which is mounted on the glue-coating frame 1. The driving wheel 22 is mounted on the output shaft of the drive motor 21, and the driven wheel 23 is mounted on one end of the transmission shaft. The other end of the transmission shaft is connected to the eccentric bearing shaft of the eccentric bearing 20. The remaining structure is the same as in Embodiment 1 and will not be described further here.
[0046] The sheet material is placed on the support platform or conveyor belt within the frame 12. The glue-spraying walking mechanism activates, and the glue-spraying beam 11 carries the glue-spraying assembly 2 along the frame 12. The glue-spraying nozzles of the glue-spraying assembly 2 can apply glue to the surface of the sheet material. The height of the glue-spraying nozzles can be adjusted according to actual needs using the glue-spraying lifting mechanism, ensuring a suitable glue-spraying height between the nozzles and the glue-spraying surface of the sheet material. The glue-spraying path adjustment mechanism can drive the glue-spraying mounting plate 3 to swing relative to the glue-spraying frame 1. The glue path can be straight. After the glue-spraying nozzle position is adjusted, the glue-spraying path adjustment mechanism stops operating. Alternatively, the piston of the drive cylinder 9 can be adjusted. The extension of the rod adjusts the glue-applying mounting plate 3 into position, and the adjustment drive cylinder 9 stops moving. Under the action of the glue-applying travel mechanism, the glue-applying nozzle moves along the initial glue-applying line on the board. After the initial glue-applying is completed, before the glue-applying assembly 2 returns, the piston rod of the adjustment drive cylinder 9 retracts, so that after the glue-applying mounting plate 3 is in position, the glue-applying assembly 2 returns under the action of the glue-applying travel mechanism. The return glue-applying line fills the gap between the adjacent initial glue-applying lines. Of course, the glue-applying line can also be wavy. If the adjustment drive cylinder 9 is kept in the extension and retraction state during the return, the return glue-applying line can also be wavy to fill the gap between the initial glue-applying lines, thereby improving the bonding quality between adjacent boards.
[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
