[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] like Figures 1 to 6As shown, the adjustable veneer gluing device described in the present invention includes a frame 1, and the frame 1 is provided with a plurality of conveying rollers 1-1 along the X direction, and the driving mode of the conveying roller 1-1 is essentially the same as that of the prior art; it also includes an active rubber roller 6, a driven rubber roller 61 and a pressure roller 7 arranged on the frame 1, and the pressure roller 7 is located on the right side of the active rubber roller 6; the upper end surfaces of the conveying roller 1-1 and the driven rubber roller 61 are in the same plane, and it is convenient for the veneer to pass through the upper end surfaces of the conveying roller 1-1 and the driven rubber roller 61; the active rubber roller 6 and the pressure roller 7 are also connected to a motor that drives them to rotate, and this technology is essentially the same as that of the prior art.

[0037] The lifting mechanisms 3 are symmetrically arranged on both sides of the frame 1, and the lifting mechanisms 3 on both sides synchronously drive the active rubber roller 6 to move away from or toward the driven rubber roller 61, and the lifting mechanisms 3 drive the pressure roller 7 to move along the Y direction; the gap between the active rubber roller 6 and the pressure roller 7 is a space for adding glue;

[0038] The lifting mechanism 3 is connected to a translation mechanism 8, which drives the pressure roller 7 to move along the X direction. The lifting mechanism 3 is used to control the gap between the active rubber roller 6 and the driven rubber roller 61, and the translation mechanism 8 can be used to adjust the gap between the pressure roller 7 and the active rubber roller 6, so as to control the flow rate and thickness of the glue.

[0039] Furthermore, in order to improve the accuracy of the gap between the active glue roller 6 and the pressure roller 7 and further effectively control the glue thickness and the quality of the glue application, the translation mechanism 8 can drive one end or both ends of the pressure roller 7 to move along the X direction.

[0040] Furthermore, the lifting mechanism 3 includes a fixed plate 3-1 fixed on the side wall of the frame 1, and the fixed plate 3-1 is slidably connected to a top plate 3-4 that can move along the Y direction, specifically: the top plate 3-4 is fixedly connected to a slider 3-52, the slider 3-52 is movably connected to a guide rail 3-51, and the guide rail 3-51 is fixedly connected to the fixed plate 3-1. The top surface of the top plate 3-4 is fixedly connected to a support plate 4.

[0041] The fixed plate 3-1 is also fixedly connected to the lifter 3-2, specifically: the side wall of the fixed plate 3-1 is connected to a lifter positioning plate, and the lifter 3-2 is located and fixed on the lifter positioning plate. The telescopic rod of the lifter 3-2 is fixedly connected to the bottom end of the top plate 3-4, and the lifter 3-2 drives the top plate 3-4 and the support plate 4 to move along the Y direction.

[0042] That is, the lifter 3 - 2 drives the active rubber roller 6 to move away from or toward the driven rubber roller 61 .

[0043] The lifter 3-2 in this example is a worm gear lifter, and the two lifters 3-2 are connected by a rotating shaft. The lifting operation of the two lifters 3-2 can be achieved by operating any one of the lifters 3-2, thereby realizing synchronous drive.

[0044] Furthermore, the lifting mechanism 3 also includes a cylinder 3-3, the bottom of the cylinder 3-3 is fixedly connected to the telescopic rod of the lifter 3-2, and the telescopic rod of the cylinder 3-3 is fixedly connected to the bottom end of the top plate 3-4. The cylinder 3-3 and the lifter 3-2 can both drive the top plate 3-4 and the support plate 4 to move along the Y direction; that is, the lifter 3-2 and the cylinder 3-3 can both drive the active rubber roller 6 to move away from or toward the driven rubber roller 61.

[0045] Furthermore, the two ends of the active rubber roller 6 are respectively fixed on the support plate 4 in the corresponding direction through the bearing seat 5; when the telescopic rod of the cylinder 3-3 extends outward, the top plate 3-4 moves upward along the Y direction with the support plate 4, the active rubber roller 6, and the pressure roller 7; when the telescopic rod of the cylinder 3-3 retracts, the top plate 3-4 moves downward along the Y direction with the support plate 4, the active rubber roller 6, and the pressure roller 7; of course, the movement of the top plate 3-4 in the Y direction can also be driven by the lifter 3-2, and the coexistence of the two driving modes can increase the stroke and the precision of the movement.

[0046] Furthermore, the translation mechanism 8 includes a translation plate 8-6 and a translation push rod 8-1 fixedly connected to the translation plate 8-6.

[0047] The support plate 4 is movably connected with the translation plate 8-6 through the translation guide rail 8-4 and the translation slider 8-5 in sequence, specifically: the support plate 4 is fixedly connected to the translation guide rail 8-4, the translation guide rail 8-4 is movably connected to the translation slider 8-5, and the translation slider 8-5 is fixedly connected to the translation plate 8-6; a translation seat 8-3 is arranged on the support plate 4, and the two translation seats 8-3 are connected by a hand grip 8-2, and the screw thread arranged at the other end of the translation push rod 8-1 extends into the translation seat 8-3 and is threadedly connected with the threaded section of the hand grip 8-2, and the hand grip 8-2 is rotated to move the translation push rod 8-1 along the X direction.

[0048] When the hand grip rod 8-2 is rotated clockwise or counterclockwise, the translation push rod 8-1 moves in the left direction of the X direction and moves the pressure roller 7 toward the active rubber roller 6; when the hand grip rod 8-2 is rotated counterclockwise or clockwise, the translation push rod 8-1 moves in the right direction of the X direction and moves the pressure roller 7 away from the active rubber roller 6.

[0049] Furthermore, in order to achieve the highest transmission efficiency and simplify the transmission structure, the angle between the translation push rod 8-1 and the handle rod 8-2 is a right angle.

[0050] Furthermore, in order to facilitate the recovery of glue, the inner cavity of the frame 1 is provided with a recovery tray 2 for collecting glue, and the recovery tray 2 is provided with a glue discharge pipe 2 - 1 , and one end of the glue discharge pipe 2 - 1 extends out of the frame 1 .

[0051] Furthermore, the hand grip 8-2 includes a left hand grip 8-2a and a right hand grip 8-2e, one end of the left hand grip 8-2a is tightly sleeved with a grip bearing 8-2f, and the outer ring of the grip bearing 8-2f is tightly sleeved in the inner hole of one end of the right hand grip 8-2e; the outer wall of the left hand grip 8-2a is fixedly sleeved with a left retaining ring 8-2b, one end face of the left retaining ring 8-2b is fixedly connected with a spring 8-2c, one end of the spring 8-2c is fixedly connected with a right retaining ring 8-2d, the right retaining ring 8-2d is provided with a key slot, and the outer circular wall of the right hand grip 8-2e is provided with a key strip 8-2e1 matching the key slot; the spring 8-2c can enable the key slot to be embedded in the key strip 8-2e1; the right retaining ring 8-2d squeezes the spring 8-2c to the left, overcomes its elastic potential energy, and enables the key slot to leave the key strip 8-2e1.

[0052] When the key slot is embedded in the key bar 8-2e1, the rotating hand grip rod 8-2 can simultaneously drive both ends of the pressure roller to move along the X direction. When the key slot leaves the key bar 8-2e1, the rotating hand grip rod 8-2 can only drive the left end of the pressure roller to move along the X direction.

[0053] When the present invention is used, the active rubber roller is driven by the lifting mechanism so that the active rubber roller can move away from or toward the driven rubber roller, and the pressure roller is driven by the translation mechanism. The translation mechanism can be used to adjust the gap between the pressure roller and the active rubber roller, so as to facilitate the control of the flow and thickness of the glue, and realize easy control of the glue thickness and facilitate the subsequent process. The translation mechanism can drive one end or both ends of the pressure roller to move along the X direction, greatly improving the accuracy of the glue thickness and further effectively controlling the glue quality.
