Description

Technical Field

[0001] The utility model relates to the technical field of plywood manufacturing, in particular to a double-sided gluing device for plywood manufacturing. Background Art

[0002] Plywood, also known as multi-layer board or laminated board, is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood squares into thin wood, and then gluing them together with adhesives. It usually uses an odd number of veneers, and the fibers of adjacent layers of veneers are glued perpendicular to each other.

[0003] Currently, in order to speed up the production of plywood, a gluing device (composed of a rubber roller and a scraper) is used to efficiently and evenly apply glue to both sides of the plywood. After the gluing is completed, pre-prepared boards are placed on both sides of the plywood, and squeezed to ensure that the boards are tightly combined, thereby completing the production of the plywood.

[0004] However, although the existing gluing device can complete the gluing work of plywood very well, in actual use, it is necessary to constantly add glue to the rubber roller, which easily leads to excessive glue residue on the surface of the rubber roller. The glue continues to accumulate on the rubber roller and eventually drips. This phenomenon not only causes a large amount of glue waste, but also increases the overall production cost of plywood.

[0021] The double-sided gluing device for manufacturing plywood according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] The double-sided gluing device for plywood manufacturing provided by the embodiment of the utility model can be applied to the production of plywood, avoids the situation where excessive glue remains on the surface of the rubber roller, and reduces the cost of plywood production.

[0023] like Figure 1-Figure 3 As shown, the double-sided gluing device for plywood manufacturing according to the embodiment of the present invention may include a mounting frame 1 , a gluing assembly 2 , a gluing mechanism 3 and a gluing scraping assembly 4 .

[0024] It should be noted that the installation frame 1 described in the above embodiment is arranged in a U-shaped structure.

[0028] It should be noted that the glue discharging mechanism 3 described in the above embodiment is provided with two groups, and the two groups of glue coating components 2 are arranged opposite to each other.

[0029] Among them, the glue box 31 is connected to the mounting frame 1, the mounting sleeve 32 is installed inside the glue box 31, the glue outlet component 33 is installed on one side of the glue box 31, the control component 34 is installed inside the glue outlet end of the glue outlet component 33, the top end of the control component 34 penetrates into the interior of the mounting sleeve 32, and the glue outlet end of the glue outlet component 33 is set through the bottom end of the glue box 31.

[0030] It should be noted that the glue box 31 described in the above embodiment has a glue filling port on its top.

[0031] Specifically, the glue is stored under the action of the glue box 31, and then the glue coating component 2 is squeezed and presses the glue discharge component 33. Under the action of the glue discharge component 33, the glue inside the glue box 31 is extracted through the installation sleeve 32 and discharged to the glue coating component 2 to complete the glue application. After that, the glue on the glue coating component 2 is replenished to avoid the glue being discharged to the glue coating component 2 all the time, resulting in excessive glue on the glue coating component 2 and dripping.

[0032] The glue scraping assembly 4 is installed on the inner side of the installation frame 1 , and the glue scraping assembly 4 is arranged on one side of the glue coating assembly 2 .

[0033] It can be understood that the scraping assembly 4 can scrape off excess glue on the plywood.

[0034] Specifically, during the actual operation, the relevant personnel place the plate on the inner side of the two groups of glue coating components 2. The plate will stretch the glue coating components 2 during the movement, and the glue discharging component 33 will be lifted up by the glue coating component 2. Then, the glue in the glue box 31 will be discharged to the glue coating component 2 through the installation sleeve 32. Then, under the transmission and coating of the glue coating component 2, the transmission and glue coating of the plate are completed. Then, under the action of the scraping component 4, the excess glue on the plate is scraped off, avoiding the situation where too much glue on the plate causes glue to overflow during the extrusion process, avoiding the situation where too much glue remains on the surface of the rubber roller, and reducing the cost of plywood production.

Then, under the action of the glue discharge component 33, the glue is discharged from the glue box 31 to the glue coating roller 21 through the installing sleeve 32, completing the coating and transmission of glue on both sides of the plates.

[0039] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the glue discharge assembly 33 may include a glue pump 331 and a glue discharge hose 332 .

[0041] Specifically, under the action of the glue pump 331 , glue is extracted from the glue box 31 and discharged onto the glue coating roller 21 through the glue discharge pipe 332 .

[0042] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the control assembly 34 may include a transmission rod 341 , a switch 342 , a return spring 343 and a ball 344 .

[0043] It should be noted that the friction between the glue coating roller 21 and the transmission rod 341 is reduced under the action of the ball 344 .

[0044] Among them, the bottom end of the transmission rod 341 slides into the internal setting of the glue discharge tube 332, and the top end of the transmission rod 341 slides into the internal setting of the mounting sleeve 32.

The return spring 343 is connected to the transmission rod 341, and the ball 344 is rotatably installed at the bottom end of the transmission rod 341.

[0045] Specifically, after the glue roller 21 is stretched open by the plate, the ball 344 contacts the glue roller 21, and then the transmission rod 341 is pushed upward under the action of the return spring 343 and the ball 344, and the glue pump 331 is driven through the switch 342, thereby completing the extraction of glue.

[0046] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the scraper assembly 4 may include an upper scraper 41 , a lower scraper 42 and a glue removal plate 43 .

[0050] Specifically, the glue on the plate is scraped off by the upper scraper 41 and the lower scraper 42 , and then the scraped glue is discharged to the inside of the glue box 31 at the bottom through the glue discharge plate 43 , completing the recycling and reuse of the glue.

[0051] In summary, the double-sided gluing device for plywood manufacturing in the embodiment of the utility model completes the gluing and transmission of the plywood under the action of the gluing component, and then achieves the effect of replenishing glue by the gluing component with the assistance of the glue discharging mechanism. After the gluing is completed, the excess glue on the plywood is scraped out by the glue scraping component, thereby completing the gluing step, avoiding the situation where there is excessive glue residue on the surface of the rubber roller, and reducing the cost of plywood production.
