Description

Technical Field

[0001] This utility model relates to the field of fiberboard production technology, and more specifically, to a glue injection device for fiberboard production. Background Technology

[0002] The core manufacturing process of fiberboard is to mix wood fibers with adhesives evenly and then hot-press them into shape. The glue injection process (precisely and evenly applying glue to the fibers) is the key step that determines the quality (strength, environmental friendliness, and stability) and production efficiency of the board, and it is also where the technical difficulty lies.

[0003] Traditional glue dispensing devices typically use threaded connections or bolts to fix the nozzles. When replacing or cleaning them, special tools are needed to repeatedly tighten them, which is cumbersome and can easily cause the nozzle and the discharge pipe to become misaligned due to uneven force, affecting the spraying accuracy. High-viscosity glues (such as low-temperature UF glue or MDI glue) flow slowly in the pipeline and are prone to accumulating, solidifying and clogging at the nozzle. In addition, low-pressure conveying can easily lead to uneven spraying and fluctuations in glue volume. Utility Model Content

[0029] Please see Figures 1-5A glue-injection device for fiberboard production includes a glue-injection pipe 1, a discharge pipe 2 on the glue-injection pipe 1, a nozzle 3 on the discharge pipe 2, connecting rods 4 symmetrically arranged on the nozzle 3, and connectors 5 on the connecting rods 4. The discharge pipe 2 has a connecting groove 6 that mates with the connecting rods 4 and connectors 5, and a connecting hole 7 that mates with the connectors 5. A fixing rod 8 is provided on the discharge pipe 2, and a fixing head 9 is provided on the fixing rod 8. A fixing ring 10 is provided on the nozzle 3, and a fixing groove 11 that mates with the fixing rod 8 and fixing head 9 is provided on the fixing ring 10. One end of the fixing groove 11 has a fixing hole 12 that mates with the fixing head 9. The other end is provided with a fixing groove 13 that cooperates with the fixing head 9. A movable collar 14 is sleeved on the outside of the discharge pipe 2. The movable collar 14 is fixedly connected to the fixing rod 8. A movable rod 15 is provided on the movable collar 14. A movable head 16 is provided on the movable rod 15. A movable ring 17 is fixedly provided on the discharge pipe 2. A movable slide groove 18 that cooperates with the movable rod 15 and the movable head 16 is provided inside the movable ring 17. A plurality of movable grooves 19 are provided on the movable slide groove 18. The movable grooves 19 correspond to the positions of the fixing groove 13 and the fixing hole 12. A movable plate 20 is slidably provided on the movable rod 15. A movable spring 21 is provided between the movable plate 20 and the movable head 16.

[0030] In this embodiment, when installing the nozzle 3, the connector 5 of the nozzle 3 is inserted into the connecting hole 7, and the connector 5 and the connecting rod 4 are rotated 90 degrees in the connecting groove 6, so that the connector 5 is misaligned with the connecting hole 7, thereby limiting the vertical movement of the nozzle 3 and the discharge pipe 2. At the same time, after the nozzle 3 is rotated 90 degrees, the fixing head 9 is aligned with the fixing hole 12, and the moving collar 14 is held. The moving collar 14 drives the fixing rod 8 and the fixing head 9 to move downward and extend into the fixing hole 12. At the same time, the moving collar 14 drives the moving rod 15 and the moving head 16 to move downward within the moving ring 17, compressing the moving spring 21. When the moving head 16 and the moving rod 15 cooperate to extend into the moving groove 18, the fixing rod 8 and the fixing head 9 pass through the fixing hole 12. The nozzle 14 extends into the fixed slide groove 11 and then rotates 90 degrees in the same direction as the connecting rod 4, causing the moving collar 14 to rotate. The moving collar 14 drives the moving rod 15, the moving head 16, the moving plate 20, and the moving spring 21 to rotate on the moving slide groove 18. The fixed head 9 and the fixed rod 8 rotate on the fixed slide groove 11. After rotating 90 degrees, the moving head 16 aligns with the moving groove 19. Under the elastic force of the moving spring 21, the moving head 16 and the moving rod 15 move upward. Then, the moving collar 14 drives the fixed rod 8 and the fixed head 9 to move upward and engage with the fixed groove 13. This limits the horizontal position of the nozzle 3 and the discharge pipe 2, thereby fixing the position of the nozzle 3 and improving the ease of installation of the nozzle 3. The nozzle 3 can be disassembled by reversing the operation.

[0031] Please see Figure 5As one embodiment of the glue injection tube 1: the glue injection tube 1 is provided with an installation plate 22 and an electric telescopic rod 23. The output end of the electric telescopic rod 23 is provided with a piston plate 24 inside the glue injection tube 1. The piston plate 24 is provided with a protective pad 25. The inner wall of the glue injection tube 1 is provided with a heating plate 26. The outer wall of the glue injection tube 1 is provided with a heat insulation layer 27.

[0032] More specifically, the dispensing tube 1 is equipped with a pipe and valve connected to the dispensing pipeline. After the adhesive enters the dispensing tube 1, it is heated by the heating plate 26 and kept warm by the insulation layer 27, which improves the fluidity of the adhesive. Then, the piston plate 24 is driven by the electric telescopic rod 23 to dispense the adhesive. The dispensing method is simple and convenient.

[0033] In summary, during the use or operation of the overall equipment: when installing the nozzle 3, the connector 5 of the nozzle 3 is inserted into the connecting hole 7, and the connector 5 and the connecting rod 4 are rotated 90 degrees in the connecting groove 6, so that the connector 5 is misaligned with the connecting hole 7, thereby limiting the vertical movement of the nozzle 3 and the discharge pipe 2. Simultaneously, after the nozzle 3 rotates 90 degrees, the fixing head 9 aligns with the fixing hole 12, and the moving collar 14 is grasped. The moving collar 14 drives the fixing rod 8 and the fixing head 9 to move downwards and extend into the fixing hole 12. At the same time, the moving collar 14, within the moving ring 17, drives the moving rod 15 and the moving head 16 to move downwards, compressing the moving spring 21. When the moving head 16 and the moving rod 15 cooperate to extend into the moving groove 18, the fixing rod 8 and the fixing head 9 pass through... The fixing hole 12 extends into the fixing groove 11, and then drives the moving collar 14 to rotate 90 degrees in the same direction as the connecting rod 4. The moving collar 14 drives the moving rod 15, the moving head 16, the moving plate 20 and the moving spring 21 to rotate on the moving groove 18. The fixing head 9 and the fixing rod 8 rotate on the fixing groove 11. After rotating 90 degrees, the moving head 16 is aligned with the moving groove 19. Under the elastic force of the moving spring 21, the moving head 16 and the moving rod 15 move upward. Then, through the moving collar 14, the fixing rod 8 and the fixing head 9 move upward and are engaged in the fixing groove 13. This limits the horizontal position of the nozzle 3 and the discharge pipe 2, thereby fixing the position of the nozzle 3 and improving the ease of installation of the nozzle 3. The nozzle 3 can be disassembled by reversing the operation.

[0034] The dispensing tube 1 is equipped with a pipe and valve connected to the dispensing pipeline. After the adhesive enters the dispensing tube 1, it is heated by the heating plate 26 and kept warm by the insulation layer 27, which improves the fluidity of the adhesive. Then, the piston plate 24 is driven by the electric telescopic rod 23 to dispense the adhesive. The dispensing method is simple and convenient.
