Description

Technical Field

[0001] The utility model relates to the technical field of pallet processing, and particularly relates to a glue spraying device for processing wood chip pallets. Background Art

[0002] A pallet is a medium that transforms static goods into dynamic goods, and is commonly used in fields such as logistics, warehousing, and transportation; a pallet is a movable platform, or a movable ground. Even goods that lose flexibility when placed on the ground immediately gain mobility once loaded onto the pallet and become flexible mobile goods because the goods loaded on the pallet are always in a state ready to move at any time.

[0003] An existing type of pallet is made by extruding and forming recycled waste wood, waste wood chips, sawdust wood chips, etc. through a hot press. Glue is required to stick the wood chips together during the production process of the pallet. The mixing of wood chips and glue is an important step in making the pallet. The existing method of mixing wood chips and glue is usually to simultaneously introduce a large amount of wood chips and glue into a mixer for mixing and stirring. However, this mixing method will cause the phenomenon of wood chip agglomeration, reducing the mixing effect of wood chips and glue solution. Moreover, the existing stirring mechanism has a single structure, resulting in poor stirring effect. At the same time, when the glue is placed for a long time, the glue is prone to precipitation, resulting in unbalanced adhesiveness of the glue. Summary of the Utility Model

Detailed implementation manners

[0016] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the drawings, but the present invention is not limited to these embodiments.

[0017] The present invention provides a glue spraying device for processing wood chip trays, including a mounting frame 1. A mixing tank 2 is installed on the mounting frame 1. A discharge port 24 is provided at the bottom of the mixing tank 2. A blanking hopper 3 is provided on one side of the mixing tank 2. The discharge port of the blanking hopper 3 is connected to the side wall of the mixing tank 2 through a material guiding frame 4. A spraying mechanism is provided in the mixing tank 2. A glue tank 6 is installed on the top of the mixing tank 2 through a support 5. A feed port 25 is opened at the top of the glue tank 6. The spraying mechanism includes a spraying pipe 7 and a "person"-shaped glue pipe 8. A plurality of spray holes are opened at the bottom of the spraying pipe 7. One end of the glue pipe 8 is communicated with the spraying pipe 7. The other end of the glue pipe 8 passes through the mixing tank 2 and is rotatably connected to the top of the glue tank 6 through a bearing. A plurality of glue inlet holes 9 and stirring blades 14 are opened on the pipe wall of the glue pipe 8 located in the glue tank 6. A driving mechanism for driving the glue pipe 8 to rotate is provided on the mixing tank 2.

[0018] As Figure 1 and 2 shown, wood chip raw materials are placed in the blanking hopper 3, which can be used to quantitatively convey the wood chip raw materials into the mixing tank 2. By controlling the rotation speed of the glue pipe 8, the glue in the glue tank 6 can enter the spraying pipe 7 along the glue inlet holes 9 and be sprayed into the mixing tank 2 along the spray holes. The driving mechanism drives the glue pipe 8 to rotate, directly driving the spraying pipe 7 to rotate, so that the glue is evenly sprayed onto the wood chip raw materials, and then the wood chip raw materials and the glue liquid are fully mixed in the mixing tank 2; it can avoid the phenomenon of agglomeration when a large amount of wood chips and glue are mixed, improve the mixing effect of the wood chips and the glue liquid, and at the same time, the stirring blades 14 rotate to stir the glue in the glue tank 6, reducing the occurrence of the situation that the glue is prone to precipitation during long-term placement, resulting in unbalanced adhesiveness of the glue.

[0019] The driving mechanism includes a driven gear 10. The driven gear 10 is installed on the outer wall of the glue pipe 8 between the mixing tank 2 and the glue tank 6. A driving motor 11 is provided on the top of the mixing tank 2. The output end of the driving motor 11 is connected with a driving gear 12 meshing with the driven gear 10.

[0020] As Figure 2 shown, under the action of the driving gear 12 and the driven gear 10, the driving motor 11 drives the rubber water pipe 8 to rotate, indirectly drives the stirring blade 14 to stir the glue in the glue tank 6, and at the same time drives the spraying pipe 7 to rotate to evenly spray glue on the wood chips in the mixing tank 2.

[0021] A stirring shaft 13 is arranged in the mixing tank 2, multiple groups of stirring components are arranged on the stirring shaft 13, and a first motor 15 for driving the stirring shaft 13 to rotate is arranged at the bottom of the mounting frame 1.

[0022] As Figure 2 shown, the first motor 15 drives the stirring components to rotate to mix the wood chips and the glue. In this embodiment, both ends of the stirring shaft 13 pass through the outer wall of the mixing tank 2 and are rotatably connected to the mounting frame 1 through supports. A large gear is installed at any one end of the stirring shaft 13. A rotating shaft is rotatably installed on the mounting frame 1, and a small gear and a pulley meshing with the large gear are respectively installed at both ends of the rotating shaft. The first motor 15 drives the pulley to rotate through a belt, indirectly driving the stirring shaft 13 to rotate.

[0023] There are two groups of the stirring components. Each group of stirring components includes a sleeve 16 sleeved on the stirring shaft 13, a mounting frame 17 rotatably installed on the sleeve 16, and a large conical tooth 18 fixedly connected to one end of the sleeve 16. The other end of the sleeve 16 is fixedly connected to the inner wall of the mixing tank 2 to ensure that the large conical gear 18 is in a fixed state. Two small conical teeth 19 are meshed with the large conical tooth 18. The large conical tooth 18 and the small conical teeth 19 are both located in the mounting frame 17. A rotating shaft 20 with the same number as the small conical teeth 19 is rotatably connected to the stirring shaft 13. The small conical teeth 19 are fixedly installed on the rotating shaft 20, and a plurality of stirring blades 21 are fixedly connected to the outer wall of the rotating shaft 20 away from the mounting frame 17.

[0024] As Figure 2 shown, the first motor 15 drives the pulley to rotate through a belt to drive the stirring shaft 13 to rotate, indirectly driving the rotating shaft 20 to rotate. Since the large conical tooth 18 is fixed, the rotating shaft 20 is rotatably installed on the stirring shaft 13 and the stirring shaft 13 is rotatably installed in the sleeve 16. Therefore, while the rotating shaft 20 rotates with the stirring shaft 13, the small conical tooth 19 will rotate along the large conical tooth 18, driving the rotating shaft 20 to rotate. At the same time, the mounting frame 17 will also rotate along the sleeve 16 with the rotation of the small conical tooth 19, so that the stirring blades 21 on the rotating shaft 20 revolve around the stirring shaft 13 while the stirring blades 21 rotate with the rotating shaft 20, which can greatly improve the stirring effect. The mounting frame 17 is used to wrap the large conical tooth 18 and the small conical teeth 19 to prevent the wood chips from affecting the rotation of the large conical tooth 18 and the small conical teeth 19.

[0025] A material discharging roller 22 is rotatably installed inside the discharging end at the bottom of the material discharging hopper 3, and a second motor 23 for driving the material discharging roller 22 to rotate is arranged on one side of the material discharging hopper 3.

[0026] As Figure 2 shown, the rotation of the second motor 23 driving the material discharging roller 22 can quantitatively convey wood chips into the mixing tank 2, and the material discharging can be carried out intermittently in small amounts and multiple times, avoiding the mixing of a large amount of wood chip raw materials and glue, reducing the phenomenon that the wood chips and glue are not fully mixed, and improving the uniformity of the mixing of the wood chips and glue.

[0027] A discharging port 24 is arranged at the bottom of the mixing tank 2, and a feeding port 25 is opened at the top of the glue tank 6.

[0028] As Figure 2 shown, the discharging port 24 is used to discharge the mixed wood chips. A valve can be arranged on the discharging port 24 for discharging the wood chips at a fixed time. The feeding port 25 is used to inject glue into the glue tank 6 to ensure that there is sufficient glue in the glue tank 6.

[0029] Principle of use: Start the second motor 23 to drive the material discharging roller 22 to rotate and convey wood chips into the mixing tank 2. At the same time, start the driving motor 11 to drive the glue pipe 8 to rotate, drive the spraying pipe 7 and the stirring blades 14 to rotate. The stirring blades 14 stir the glue in the glue tank 6. The glue in the stirring tank 6 enters the spraying pipe 7 along the glue inlet holes 9. The spraying pipe 7 rotates to evenly spray the glue onto the wood chips. At the same time, the second motor 23 drives the material discharging roller 22 to rotate and quantitatively convey wood chips into the mixing tank 2. Start the first motor 15 to drive the stirring shaft 13 to rotate, drive the stirring blades 21 to rotate around the stirring shaft 13. The rotation of the stirring shaft 13 drives the small conical gear 19 to rotate, indirectly drives the rotating shaft 20 connected to the small conical gear 19 to rotate, and enables the stirring blades 21 to rotate self - sufficiently, which can greatly improve the stirring effect of the wood chip raw materials and the glue. The well - stirred mixture is discharged from the discharging port 24.
