Gluing device for plywood processing

Abstract

The utility model relates to the technical field of plywood processing, and in particular to a gluing device for plywood processing. Existing gluing devices for plywood processing basically use a gluing roller to apply glue to the plywood.

A gluing device for plywood processing includes a base frame, etc.; a limiting groove is opened on the top of the base frame, and two electric slide rails are fixedly connected to the base frame, and the two electric slide rails are symmetrically arranged. The glue is quickly and evenly applied to the surface of the gluing roller through the discharging roller, and the two sliders drive the gluing roller to continue to move, so that the gluing roller contacts the surface of the plywood, and the surface of the plywood is quickly glued, thereby improving the efficiency of the plywood gluing process.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] Embodiment 1: A glue coating device for plywood processing, such as Figure 1 , Figure 2 and Figure 5 As shown, it includes a base frame 1, a limiting groove is opened on the top of the base frame 1, two electric slide rails 2 are fixedly connected to the base frame 1, the two electric slide rails 2 are symmetrically arranged, and sliders 3 are slidably connected to the two electric slide rails 2. A fixed frame 4 is fixedly connected between the tops of the two sliders 3, and the upper part of the fixed frame 4 is fixedly connected to a glue storage box 5, and the bottom of the glue storage box 5 is rotatably connected to a discharge roller 51, and the discharge roller 51 is used to bring out the glue in the glue storage box 5, and the lower part of the fixed frame 4 is rotatably connected to a glue coating roller 6, and the glue coating roller 6 is used to glue the gluing surface, and the glue coating roller 6 is located below the glue storage box 5, and the glue coating roller 6 contacts the discharge roller 51, and both ends of the glue coating roller 6 are fixedly connected to a driving gear 7, and the two driving gears 7 are symmetrically arranged. Two racks 8 are fixedly connected to the top of the base frame 1, and the driving gear 7 is meshed with the rack 8.

[0018] At first, the worker places the plywood on the limiting groove of the bottom frame 1, and the worker starts the electric slide rail 2, which drives the slider 3 to move. The two sliders 3 drive the fixed frame 4, the glue storage box 5, the discharge roller 51, the glue coating roller 6 and the driving gear 7 to move along the electric slide rail 2, so that the driving gear 7 rotates. The rotation of the driving gear 7 drives the glue coating roller 6 to rotate. The rotation of the glue coating roller 6 drives the discharge roller 51 to rotate. The rotation of the discharge roller 51 brings the glue in the glue storage box 5 out of the glue storage box 5, and the glue is quickly and evenly applied to the surface of the glue coating roller 6 through the discharge roller 51. The two sliders 3 drives the glue coating roller 6 to continue to move, so that the glue coating roller 6 contacts the surface of the plywood, and quickly coats the surface of the plywood with glue, thereby improving the efficiency of the plywood coating process, until the two sliders 3 move to the end of the electric slide rail 2, and the glue coating roller 6 completes coating the plywood with glue, and the worker can take the glued plywood out of the limiting groove of the bottom frame 1, and then the worker controls the electric slide rail 2, and the electric slide rail 2 drives the two sliders 3 to move in the opposite direction and reset, and the two sliders 3 drive the fixed frame 4, the glue storage box 5, the discharge roller 51, the glue coating roller 6 and the driving gear 7 to move in the opposite direction and reset along the electric slide rail 2.

[0019] Embodiment 2: Based on embodiment 1, Figure 2 As shown, it also includes a support frame 9, the upper part of the fixed frame 4 is slidably connected to the support frame 9, two return springs 10 are connected between the support frame 9 and the fixed frame 4, and the lower part of the support frame 9 away from the fixed frame 4 is slidably connected to a pressure plate 11, the pressure plate 11 is used to flatten the plywood, the pressure plate 11 is in contact with the base frame 1, and two return springs 12 are connected between the pressure plate 11 and the support frame 9.

[0020] The two sliders 3 will drive the fixing frame 4 to move towards the plywood. The movement of the fixing frame 4 will drive the supporting frame 9, the reset spring 10, the pressing plate 11 and the return spring 12 to move, so that the pressing plate 11 will contact the surface of the plywood. Under the action of the return spring 12, the pressing plate 11 will flatten the uneven surface of the plywood during the movement, so that the plywood is flattened by the pressing plate 11 and then coated with glue, so that the glue can be more evenly applied to the surface of the plywood.

[0021] Embodiment 3: Based on embodiment 2, Figure 3 As shown, it also includes a rotating rod 13. The lower part of the fixed frame 4 is rotatably connected to two rotating rods 13. The two rotating rods 13 are fixedly connected to a protrusion 14. The protrusion 14 is used to increase the extrusion force of the pressure plate 11 on the plywood. The two protrusions 14 are in contact with the support frame 9. The two rotating rods 13 are fixedly connected to a passive gear 15, and the passive gear 15 is meshed with the active gear 7.

[0022] The two sliders 3 drive the fixed frame 4, the glue roller 6, and the driving gear 7 to move in the direction close to the plywood. The rotation of the driving gear 7 will drive the driven gear 15 to rotate. The rotation of the driven gear 15 will drive the rotating rod 13 and the protrusion 14 to rotate. The rotation of the protrusion 14 will squeeze the support frame 9 to move up and down repeatedly. When the support frame 9 moves downward, the reset spring 10 is compressed, and the protrusion 14 will increase the extrusion force of the return spring 12 between the support frame 9 and the pressure plate 11, so that when the pressure plate 11 flattens the plywood, the extrusion force of the pressure plate 11 on the plywood is increased. The relatively uneven part on the plywood is flattened by the pressure plate 11 with a larger extrusion force, so that the surface of the plywood is smoother, so that the glue roller 6 can apply glue to the surface of the plywood more completely.

[0023] Embodiment 4: Based on the embodiment 3, Figure 4 As shown, a straight plate 16 is also included. The straight plate 16 is fixedly connected to one side of the support frame 9 close to the glue coating roller 6. A silicone plate 17 is fixedly connected to the bottom of the straight plate 16. The silicone plate 17 is located between the pressure plate 11 and the glue coating roller 6, and the silicone plate 17 is in contact with the base frame 1.

[0024] The two sliders 3 drive the fixing frame 4 and the supporting frame 9 to move, and the supporting frame 9 drives the straight plate 16 and the silicone plate 17 to move. The silicone plate 17 scrapes the debris on the surface of the plywood during the movement, reducing the wood chips on the surface of the plywood and making the glue liquid more evenly distributed.
