Description

Technical Field

[0001] This utility model relates to the field of wood-plastic composite flooring technology, and in particular to an adhesive applicator for the production of wood-plastic composite flooring. Background Technology

[0002] Wood-plastic composite (WPC) flooring is a new type of environmentally friendly wood-plastic composite material product. It is made by adding lignin, a byproduct of the production of medium- and high-density fiberboard, to recycled plastics through a granulation process, and then extruding the resulting material into flooring. Outdoor WPC flooring primarily consists of PE (polyethylene) and wood or bamboo powder. After adding additives and high-speed mixing, the mixture is granulated, and then extruded into finished products. This type of flooring can be used in landscaping, villas, and other outdoor platforms.

[0003] In the production process of wood-plastic composite flooring, it is necessary to apply glue to the surface of the wood-plastic flooring substrate. Existing glue application equipment applies glue to the surface of the wood-plastic flooring substrate through glue application rollers. After a period of use, some glue will remain on the surface of the glue application rollers, and this glue will dry and harden on the surface of the glue application rollers, making it difficult to clean. This will make the surface of the glue application rollers uneven, affecting normal glue application. Existing glue application equipment also has the problem that the glue application rollers are difficult to disassemble, making it inconvenient to clean the glue on the surface of the glue application rollers.

The bottom of the connecting block 14 abuts against the worktable 1. The connecting block 14 and the worktable 1 are fixedly connected by a first bolt 15.

[0020] In the above embodiment, the drive roller 2 and the coating roller 3 are engaged with each other by the positioning block 31 and the positioning groove 16. The drive roller 2 and the coating roller 3 are fixed by the limiting ring 17 and the second bolt 18, so that the two can rotate synchronously. When cleaning the glue on the surface of the coating roller 3 later, the second bolt 18 is unscrewed, the limiting ring 17 is removed, and the positioning block 31 and the coating roller 3 are slid along the trajectory of the positioning groove 16 to separate the coating roller 3 from the drive roller 2. Then the coating roller 3 can be professionally cleaned to remove the glue on the surface of the coating roller 3, so that it can be used again.

[0021] Specifically, the outer side of the drive roller 2 is provided with multiple positioning grooves 16, and the inner side of the coating roller 3 is fixedly connected with multiple positioning blocks 31, and the multiple positioning blocks 31 are respectively engaged in the corresponding positioning grooves 16.

[0022] In the above embodiment, the positioning block 31 and the positioning groove 16 engage with each other, so that the drive roller 2 and the coating roller 3 can be positioned and installed together.

[0023] Specifically, a limiting ring 17 is provided on the side of the drive roller 2 and the glue coating roller 3 near the left roller shaft. The limiting ring 17 abuts against one side of the positioning block 31, and the limiting ring 17 is fixedly connected to the drive roller 2 by a second bolt 18.

[0024] In the above embodiment, the drive roller 2 and the coating roller 3 are fixed together by the limiting ring 17 and the second bolt 18.

[0025] Specifically, the limiting frame 13 includes a stop rod 13a and a connecting rod 13b. The stop rods 13a respectively abut against the support plate 10 and the clamping plate 12 on opposite sides. The two stop rods 13a are fixedly connected by the connecting rod 13b.

[0026] In the above embodiment, by having the stop bar 13a abut against the side of the support plate 10 and the clamping plate 12 that are far apart from each other, the movement of the support plate 10 and the clamping plate 12 is restricted.

[0027] Specifically, a second slide groove 19 is provided in the workbench 1, a second slider 20 is slidably installed in the second slide groove 19, and a support base 21 is fixedly installed on the top of the second slider 20.

[0028] In the above embodiment, the support base 21 serves as a support, allowing the coating roller 3 to slide along the top of the support base 21.

[0029] Specifically, the support plate 10 has a reserved hole 22, and the support base 21 can pass through the inside of the reserved hole 22.

[0030] In the above embodiment, the support seat 21 passes through the reserved hole 22 and then reaches below the coating roller 3.

[0031] Specifically, glue storage tanks 23 are provided on both sides of the top of the workbench 1. A glue pump is fixedly installed on the bottom inner wall of the glue storage tank 23. A glue spraying pipe 24 is fixedly installed on the outlet end of the glue pump. The top of the glue spraying pipe 24 passes through and extends to the outside of the glue storage tank 23. Multiple evenly distributed glue spraying heads 25 are fixedly installed at the bottom of the glue spraying pipe 24.

[0032] In the above embodiment, glue is drawn from the glue storage tank 23 by a glue pump and sent into the glue spraying pipe 24, and then the glue is continuously sprayed onto the surface of the wood-plastic flooring substrate 29 by multiple glue spraying heads 25.

[0033] Specifically, the right roller is sleeved in the inner ring of the right bearing, the right bearing is fixedly installed inside the fixed plate 26, and the inside of the fixed plate 26 is fixedly installed on the worktable 1.

[0034] In the above embodiment, by mounting the right roller shaft inside the right bearing, the frictional force generated when the right roller shaft rotates is reduced.

[0035] Specifically, guide rods 27 are fixedly installed on the inner walls of both sides of the first slide groove 8, and guide holes are opened in the first slider 9. The guide rods 27 are slidably sleeved on the inner side of the guide holes.

[0036] In the above embodiment, the first slider 9 moves linearly along the trajectory of the guide rod 27 by the cooperation between the guide rod 27 and the guide hole.

[0037] Working principle: The wood-plastic composite flooring substrate 29 is fed into the conveyor belt 28 from one side. The conveyor belt 28 gradually transports the wood-plastic composite flooring substrate 29 forward. A glue pump draws glue from the glue storage tank 23 and sends it into the glue spraying pipe 24. Multiple spray nozzles 25 continuously spray the glue onto the surface of the wood-plastic composite flooring substrate 29. The wood-plastic composite flooring substrate 29 then passes under the glue coating roller 3. The drive motor 6 drives the drive roller 2 and the glue coating roller 3 to rotate synchronously. The glue on the surface of the wood-plastic composite flooring substrate 29 is gradually evenly coated by the glue coating roller 3. After a period of use, when the glue remaining on the surface of the glue coating roller 3 dries and becomes difficult to clean, it is then removed along the second... The track of the slide groove 19 pushes the support seat 21, causing the support seat 21 to move below the glue coating roller 3, thereby supporting the glue coating roller 3. Unscrew the first bolt 15 to release the fixed limit frame 13, remove the limit frame 13, and then remove the clamping plate 12. Slide the support plate 10 along the track of the first slide groove 8 to move the support plate 10 from one side of the glue coating roller 3. Unscrew the second bolt 18 to remove the limit ring 17. Then, the positioning block 31 and the glue coating roller 3 can be slid along the track of the positioning groove 16. The removed positioning block 31 and the glue coating roller 3 are professionally cleaned to remove the glue adhering to the surface of the glue coating roller 3 for reuse.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
