Description

Technical Field

[0001] The utility model is applicable to the technical field of plywood production, and particularly relates to a plywood double-glue coating roller gluing machine. Background Art

[0002] At present, plywood is a three-layer or multi-layer plate material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesive. Usually, an odd number of veneers are used, and the fiber directions of adjacent layers of veneers are glued perpendicular to each other. When processing plywood, it is often necessary to use a corresponding glue coating machine to apply glue to both sides of the board to facilitate the subsequent pressing and splicing process.

[0003] However, when applying glue to the surface of plywood, the operator needs to hold the board and continuously support it to avoid any shaking during gluing, which may affect the contact area between the gluing roller and the board surface. The long-term hand-supporting not only increases the operator's labor consumption, but also fails to quickly and stably adjust the support suitability according to the thickness of the board, which can easily affect the quality of gluing during long-term gluing. Therefore, we propose a plywood double-gluing roller gluing machine. Utility Model Content

[0004] The main purpose of the utility model is to provide a plywood double-gluing roller gluing machine, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A plywood double-gluing roller gluing machine comprises a mounting base, support plates are vertically fixedly mounted on both sides of the top of the mounting base, gluing rollers are rotatably mounted on both ends of the side edges of two groups of support plates, and a sliding plate is slidably mounted on the side edges of each support plate;

[0007] A transmission frame is fixedly mounted on the outer surface of each sliding plate, a bidirectional screw rod is vertically rotatably mounted inside each transmission frame through a bearing, a transmission sleeve is movably sleeved on both ends of the outer surface of each bidirectional screw rod, a transmission frame is fixedly mounted on the outer surface of each transmission sleeve, and a rotating rod is fixedly mounted on the outer surfaces of each two groups of transmission frames;

[0008] The outer surface of each rotating rod is rotatably sleeved with a guide roller via a bearing.

[0009] By adopting the above technical scheme, the vertical position and spacing of the guide rollers can be adjusted for suitability under the rotational transmission action of the transmission sleeve by the bidirectional screw and the transmission action of the transmission frame, ensuring that the guide rollers can fit the outside of plates of different thicknesses and perform a dynamic guiding treatment on them to avoid arbitrary shaking of the plates, thereby improving the subsequent gluing quality and reducing the labor consumption required by the operator for hand support.

[0010] As an optional solution of the technical solution of the present application, a servo motor is fixedly mounted on the outer top surface of each transmission frame, and the bottom of the servo motor transmission shaft is fixedly connected to the top of the bidirectional screw rod through a coupling.

[0011] By adopting the above technical solution, the driving action of the servo motor can provide the power required for the rotation of the bidirectional screw rod.

[0012] As an optional solution of the technical solution of the present application, a limiting groove is provided at the middle end of the side of each sliding plate, and the transmission frame is slidably inserted into the limiting groove, and a connecting plate is fixedly installed on the outer end surfaces of each sliding plate, and the connecting plate is slidably fitted to the outer surface of the support plate.

[0013] By adopting the above technical solution, the transmission rationality of the entire device is ensured by the guiding and limiting effect of the limiting groove on the transmission frame.

[0014] As an optional solution of the technical solution of the present application, a clamping bolt is screwed through the middle end of each connecting plate via a thread, a sliding groove is opened on the side of each supporting plate, and the clamping bolt is slidably inserted into the sliding groove.

[0015] By adopting the above technical solution, the sliding groove is used to limit the fit of the tightening bolt, and then the position of the sliding plate and the guide roller can be limited and fixed.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. A double-gluing roller gluing machine for plywood according to the technical solution of the present application, by movably connecting a transmission sleeve to both sides of a bidirectional screw rod and combining the rotational transmission action of the bidirectional screw rod on the transmission sleeve, the two groups of transmission sleeves can be synchronously moved vertically toward or relative to each other inside the transmission frame, and then under the connection transmission action of the transmission frame, the guide roller and the transmission sleeve can be transmission-connected, so that the guide roller can be vertically moved between the two groups of sliding plates to adjust the guide spacing, ensuring that the guide roller can fit the outer side of plates of different thicknesses, and perform a moving guiding treatment on them, so as to avoid arbitrary shaking of the plates and improve the subsequent gluing quality, while reducing the labor consumption required for the operator to support them by hand.

[0018] 2. A double-gluing roller gluing machine for plywood according to the technical solution of the present application has connecting plates installed on both sides of the sliding plate, so that the positions of the connecting plates and the sliding plates can be vertically moved and adjusted, thereby driving the two sets of guide rollers to move vertically synchronously on the outside of the gluing rollers, adjusting the guide positions of the guide rollers, ensuring that the gaps between the guide rollers can be adjusted according to the positions of the gluing rollers, and further improving the gluing support stability of the board.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), each connecting plate 3 has a locking bolt 32 threadedly inserted through the middle end, each supporting plate 11 has a sliding groove 31 on the side, and the locking bolt 32 is slidably inserted into the sliding groove 31, and each sliding plate 2 has a connecting plate 3 fixedly installed on both end surfaces of the outer side, and the connecting plate 3 is slidably fitted to the outer surface of the supporting plate 11.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3As shown), a servo motor 22 is fixedly mounted on the outer top surface of each transmission frame 21, and the bottom of the servo motor 22 transmission shaft is fixedly connected to the top of the bidirectional lead screw 23 through a coupling, a transmission frame 21 is fixedly mounted on the outer surface of each sliding plate 2, and a bidirectional lead screw 23 is vertically rotatably mounted inside each transmission frame 21 through a bearing, a transmission sleeve 24 is movably sleeved on the outer end surfaces of each bidirectional lead screw 23, a transmission frame 25 is fixedly mounted on the outer surface of each transmission sleeve 24, and a rotating rod 26 is fixedly mounted on the outer surfaces of every two groups of transmission frames 25.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), the outer surface of each rotating rod 26 is rotatably sleeved with a guide roller 28 via a bearing.

[0027] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 As shown in FIG. 1 , a limiting groove 27 is provided at the middle end of the side of each sliding plate 2 , and the transmission frame 25 is slidably inserted into the limiting groove 27 .

[0028] During operation, according to the thickness of the plate to be coated with glue, the limit bolt is screwed outward to disengage it from the inner wall of the limit groove 27, and then the sliding plate 2 is pushed to adjust the positions of the two sets of guide rollers 28 so that the guide rollers 28 can be flush between the middle ends of the two sets of glue rollers 12, and then the limit bolt is screwed in the opposite direction so that the side of the limit bolt is tightly fitted against the inner wall of the limit groove 27, and the position of the guide roller 28 is reinforced.
