Description

Technical Field

[0001] This utility model relates to the field of particleboard processing technology, and in particular to a particleboard layer adhesive metering device. Background Technology

[0002] Particleboard (also called chipboard) is a commonly used engineered wood product. It is mainly made from wood waste (such as wood chips, sawdust, and wood scraps) through heating, pressurization, and adhesive bonding. Its manufacturing process involves compressing wood particles into boards, thus giving it good stability and economy. Before pressing, particleboard needs to be glued to tightly bond the wood chips, wood scraps, or fibers, forming a whole structure.

[0003] In the process of applying adhesive to particleboard, the wood chips are usually divided into different layers, such as the surface layer, core layer, and back layer. The surface and back layers have a larger amount of adhesive applied to improve surface quality, while the core layer has a relatively smaller amount, primarily serving an adhesive function. Traditional adhesive application equipment cannot achieve precise adhesive dosage adjustment, especially when dealing with the needs of different particleboard layers. This often results in insufficient or excessive adhesive, leading to uneven adhesive distribution between layers and affecting product quality. Adjusting the adhesive dosage may require manual operation, and the adjusted settings are not easily fixed and are prone to fluctuations during production. Therefore, this invention proposes a particleboard layered adhesive metering device to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a particleboard layered adhesive metering device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A particleboard layered adhesive metering device includes a first portion cylinder, a second portion cylinder, and a third portion cylinder. The second portion cylinder slides inside the first portion cylinder, and the third portion cylinder slides inside the second portion cylinder. The third portion cylinder penetrates one end of the first portion cylinder. A piston that slides inside the third portion cylinder is installed inside the third portion cylinder. An injection pipe is installed inside the piston. The inner end of the injection pipe is connected to a flexible tube located inside the third portion cylinder. The inner end of the flexible tube is connected to a three-way pipe installed inside the third portion cylinder. The first outlet of the three-way pipe is located inside the third portion cylinder, the second outlet of the three-way pipe is located inside the second portion cylinder, and the third outlet of the three-way pipe is located inside the first portion cylinder. A control valve is installed at each of the three outlets of the three-way pipe.

[0006] Preferably, a communicating vessel is provided below the portion cylinder, and a nozzle is installed on the lower side of the communicating vessel to apply glue to the particleboard.

[0007] Preferably, the inner end of the third component cylinder is connected to a flexible tube second located inside the second component cylinder, through which the glue inside the third component cylinder is discharged.

[0008] Preferably, a connecting pipe is connected between the communicating vessel and the first portion cylinder, a connecting pipe is connected between the communicating vessel and the second portion cylinder, and a connecting pipe is connected between the communicating vessel and the second flexible pipe. A control valve is installed on each of the connecting pipes.

[0009] Preferably, a stud is fixed on the upper side of the second component cylinder, and a slot corresponding to the stud is opened on the upper side of the first component cylinder, and a nut is threadedly connected to the upper end of the stud to the surface of the first component cylinder.

[0010] Preferably, a slider is fixed on the upper side of the outer end of the third component cylinder, and a corresponding limiting strip seat is fixed on the outer side of the first component cylinder. A stud is fixed on the outer end of the slider, and a nut is threaded onto the stud and tightly attached to the surface of the limiting strip seat.

[0011] Preferably, a movable plate is fixed at the outer end of the injection pipe connected to the piston, and a sleeve corresponding to the movable plate is provided on the lower side of the outer end of the third component cylinder. A stud two penetrating the movable plate is fixed on the outer side of the sleeve, and a slot corresponding to the stud two is opened inside the movable plate. A nut two tightly attached to the surface of the sleeve is threaded onto the stud two.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model adopts a nested sliding structure of one, two, and three component cylinders, which realizes three-level independent capacity adjustment through axial displacement to adapt to the glue quantity requirements of different particleboard layers. The design of the piston and component cylinder further refines the fine-tuning capability and ensures that the metering accuracy can meet the process requirements. The nested design saves space, and the sliding guide is realized through the cooperation of the slider and the limiting strip seat, which reduces the difficulty of operation. All adjustment components are located on the outside of the device, which facilitates quick adjustment of parameters during the production process. 2. The combination of studs and nuts in this utility model constitutes a multi-point fixing system. After adjustment, mechanical locking prevents displacement and ensures the stability of the glue application process. The three-way pipe, together with the flexible pipe and the three-end control valve, realizes the directional injection of glue into the designated volume cylinder, avoiding cross-contamination. The combination valve control of connecting pipes one, two, and three with the communicating vessel ensures that the glue flows in sequence during layered glue application, ensuring the accuracy of glue distribution between layers.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-3 A particleboard layered adhesive metering device includes a first portion cylinder 1, a second portion cylinder 2, and a third portion cylinder 3. The second portion cylinder 2 slides inside the first portion cylinder 1, and the third portion cylinder 3 slides inside the second portion cylinder 2. The third portion cylinder 3 passes through one end of the first portion cylinder 1. A piston 14 that slides inside and outside is provided inside the third portion cylinder 3. An injection tube is installed inside the piston 14. A stud 9 is fixed on the upper side of the second portion cylinder 2, and a slot corresponding to the stud 9 is opened on the upper side of the first portion cylinder 1. A nut 10 that fits tightly against the surface of the first portion cylinder 1 is threaded to the upper end of the stud 9. The third portion cylinder 3... A slider is fixed on the upper side of the outer end, and a corresponding limiting strip seat 18 is fixed on the outer side of the component cylinder 1. A stud 3 19 is fixed on the outer end of the slider, and a nut 3 20 that is tightly attached to the surface of the limiting strip seat 18 is threaded onto the stud 3 19. A movable plate 15 is fixed on the outer end of the injection pipe connected to the piston 14. A sleeve corresponding to the movable plate 15 is provided on the lower side of the outer end of the component cylinder 3. A stud 2 16 that penetrates the movable plate 15 is fixed on the outer side of the sleeve, and a slot corresponding to the stud 2 16 is opened inside the movable plate 15. A nut 2 17 that is tightly attached to the surface of the sleeve is threaded onto the stud 2 16. The three sub-cylinders represent the amount of glue applied to different layers, and their amounts vary depending on the specifications of the particleboard. Therefore, the amount of glue applied varies slightly. This three-way structure allows for flexible adjustment to change the internal capacity of the three cylinders, thereby achieving accurate measurement before glue application and ensuring the production quality of the particleboard. By sliding the sub-cylinder 2 inside the first sub-cylinder 1 left and right, the internal capacity of the first sub-cylinder 1 can be adjusted. By tightening or loosening the nut 10 on the stud 9, the position of the second sub-cylinder 2 inside the first sub-cylinder 1 can be fixed. By sliding the third sub-cylinder 3 inside the second sub-cylinder 2 inward and outward, the internal capacity of the second sub-cylinder 2 can be adjusted. By tightening or loosening the nut 20 on the stud 19, the position of the third sub-cylinder 3 can be fixed. By sliding and adjusting the position of the piston 14 inside the third sub-cylinder 3, the internal capacity of the third sub-cylinder 3 can be adjusted. By tightening or loosening the nut 17 on the stud 16, the position of the piston 14 inside the third sub-cylinder 3 can be fixed. The injection tube is connected to a flexible tube 12 located inside the third component cylinder 3. The flexible tube 12 is connected to a three-way tube 11 installed inside the third component cylinder 3. The first outlet of the three-way tube 11 is located inside the third component cylinder 3, the second outlet of the three-way tube 11 is located inside the second component cylinder 2, and the third outlet of the three-way tube 11 is located inside the first component cylinder 1. Control valves are installed at the three outlets of the three-way tube 11. Glue is injected into the three-way tube 11 through the injection tube and the flexible tube 12. The control valves at the corresponding ports are opened to control the glue to flow into the designated component cylinder, thereby realizing the quantitative injection of glue. A communicating vessel 4 is installed below the first component cylinder 1, and a nozzle 5 is installed on the lower side of the communicating vessel 4. The adhesive is applied to the particleboard through the nozzle 5. The inner end of the third component cylinder 3 is connected to a flexible tube 2 13 located inside the second component cylinder 2. The adhesive in the third component cylinder 3 is discharged through the flexible tube 2 13. A connecting tube 1 6 is connected between the communicating vessel 4 and the first component cylinder 1, a connecting tube 2 7 is connected between the communicating vessel 4 and the second component cylinder 2, and a connecting tube 3 8 is connected between the communicating vessel 4 and the flexible tube 2 13. Control valves are installed on the connecting tubes 1 6, 2 7, and 3 8. When the adhesive is applied to the corresponding layer, the control valve on the corresponding connecting tube is opened. For example, the adhesive in the third component cylinder 3 enters the communicating vessel 4 through the flexible tube 2 13 and the connecting tube 3 8, the adhesive in the second component cylinder 2 enters the communicating vessel 4 through the connecting tube 2 7, and the adhesive in the first component cylinder 1 enters the communicating vessel 4 through the connecting tube 1 6. Finally, all of them are sprayed out through the nozzle 5.
