Description

Technical Field

[0001] This utility model relates to a grinding structure for a wood gluing machine, belonging to the technical field of grinding structures for wood gluing machines. Background Technology

[0002] Plywood is a sheet material consisting of three or more layers of veneer, made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It typically uses an odd number of veneer layers, with the grain direction of adjacent veneer layers glued perpendicular to each other.

[0003] Existing glue-applying machines have the following problems during the glue-applying process: When transporting wood, the machine places the wood horizontally and applies glue to its surface via the glue-applying rollers. Because the wood is placed horizontally, excess glue on the surface cannot be recovered.

[0004] Application CN202322121498.4 discloses a wood production glue applicator; when applying glue to wood, the wood is placed vertically on the upper surface of several rollers, the motor drives the head roller to rotate, causing the wood to move forward, and at the same time the positioning component fixes the wood in the middle of the board groove. Meanwhile, the glue is applied by the glue applicator. After the glue is applied, under the action of gravity, the glue naturally slides down the surface of the wood, and the excess glue flows into the interior of the recycling board for recycling. At the same time, the scraper component scrapes off the excess glue, leaving a specified thickness of glue on the surface of the wood.

[0005] However, the device still has the following problems: when the plywood is applied vertically through the glue applicator, the glue will flow downwards due to gravity, resulting in uneven glue thickness on the upper and lower parts of the plywood.

[0006] Therefore, this application proposes a wood production glue applicator. Utility Model Content

Several glue outlets 7 are provided on the opposite side walls of the two distribution boxes 6. The smoothing mechanism includes two smoothing rollers 8 respectively installed on the same side of the distribution boxes 6. A long rotating frame 9 and a short rotating frame 10 located below the long rotating frame 9 are fixedly connected to the side wall of the distribution box 6 away from the feed inlet 2. The smoothing rollers 8 are installed at an angle between the long rotating frame 9 and the short rotating frame 10, and the bottom end of the smoothing rollers 8 is closer to the distribution box 6 than the top end. By setting up a smoothing mechanism, a smoothing roller 8 is inclinedly arranged on one side of the dispensing box 6, and the bottom end of the smoothing roller 8 is closer to the dispensing box 6 than the top end. Therefore, the plywood after being coated with glue will be subjected to an upward force when passing between the two smoothing rollers 8, which can prevent the glue from flowing down due to gravity and thus improve the uniformity of glue application.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, a collection box 11 is fixedly connected to the bottom of the middle part of the glue application box 1. A discharge pipe 12 is connected to the bottom of the collection box 11, and a valve is installed on the discharge pipe 12. A fixing frame 13 is fixedly installed at the bottom of the glue application box 1, and several rollers 15 driven by a first motor 14 are installed in the middle of the fixing frame 13.

By setting the adjusting mechanism, the distance between the two distribution boxes 6 can be adjusted, thus making it suitable for use with plywood of different thicknesses. In use, the second motor 18 drives the bidirectional lead screw 17 to rotate, causing the two distribution boxes 6 to move closer or further apart.

The rounded ends of the auxiliary wheel 27 prevent the plywood from being scratched when moving up and down.

[0034] In this embodiment, as Figure 1 and Figure 2 As shown, an observation window 28 is provided on the outer front wall of the glue application box 1, and a control box is provided on the glue application box 1. The glue application process can be observed through the observation window 28, and the control box on the glue application box 1 can control the operation of various electrical components.

[0035] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the smoothing structure of the wood gluing machine provided in this embodiment is as follows:

[0036] Step 1: Place the plywood into the roller 15 of the glue coating box 1 through the feed port 2, so that one end of it enters between the two dispensing boxes 6;

[0037] Step 2: Start the second motor 18 to drive the bidirectional lead screw 17 to rotate, causing the two distribution boxes 6 to move closer together and adhere to the plywood;
