Description

Technical Field

[0001] The utility model belongs to the field of atomizing glue application, and in particular relates to an atomizing glue application device for OSB and FOSB. Background Art

[0002] In the production process of OSB and FOSB (particle board), high-speed gluing is a very critical process step.

[0003] At present, high-speed gluing is achieved by using a high-speed micro motor to realize a high-speed centrifugal atomizer (6000-15000r / min). However, the high-speed centrifugal atomizer has a high temperature around the high-speed bearing during operation, and the built-in power supply and high-speed equipment are prone to static electricity. At the same time, there is also an inevitable risk of electrical short circuit. As a result, various factors make the high-speed gluing process subject to the risk of static electricity that is difficult to eliminate and fire or explosion caused by short circuit. In addition, due to the high speed, the high-speed centrifugal atomizer requires a large investment in maintenance and repair costs.

[0004] In summary, the use of high-speed centrifugal atomizers increases the risk of fire or explosion caused by static electricity and short circuits during the gluing process; and requires a large investment in maintenance and repair costs. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides an atomizing gluing device for OSB and FOSB, which can eliminate the risk of fire or explosion caused by static electricity and short circuit in the gluing process, and can greatly reduce maintenance and repair costs.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] An atomizing glue-applying device for OSB and FOSB is characterized in that it includes a compressed air pipeline, a reused fluid pipeline, an air dynamic mixer and an atomizing nozzle, wherein the compressed air pipeline and the reused fluid pipeline are both connected to the air dynamic mixer, the air dynamic mixer is connected to the atomizing nozzle, and the air dynamic mixer atomizes glue to the outside through the atomizing nozzle.

[0008] Furthermore, the connecting portion between the compressed air pipeline and the air dynamic mixer is used as the first connecting portion, and the connecting portion between the reused fluid pipeline and the air dynamic mixer is used as the second connecting portion. The first connecting portion has a longer connecting path with the nozzle than the second connecting portion.

[0009] An atomizing glue-applying device for OSB and FOSB is characterized by comprising a compressed air pipeline, a glue liquid pipeline, a curing agent pipeline, an air dynamic mixer, an expansion channel and an atomizing nozzle, wherein the compressed air pipeline, the glue liquid pipeline and the curing agent pipeline are all connected to the air dynamic mixer, the air dynamic mixer is connected to the atomizing nozzle through the expansion channel, and the air dynamic mixer atomizes glue to the outside through the atomizing nozzle.

[0010] Preferably, the length of the expansion channel is in the range of 10 cm to 30 cm.

[0011] Preferably, the expansion channel is a connecting hose.

[0012] Preferably, the connecting part between the compressed air pipeline and the air dynamic mixer is used as the first connecting part, the connecting part between the glue pipeline and the air dynamic mixer is used as the second connecting part, and the connecting part between the curing agent pipeline and the air dynamic mixer is used as the third connecting part, and the connecting paths between the first connecting part, the second connecting part and the third connecting part and the nozzle increase successively.

[0013] Preferably, isocyanate adhesive flows into the adhesive pipeline.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Because the atomizing glue applying device for OSB and FOSB of the present invention includes a compressed air pipeline, a reused fluid pipeline, an air dynamic mixer and an atomizing nozzle, the compressed air pipeline and the reused fluid pipeline are both connected to the air dynamic mixer, the air dynamic mixer is connected to the atomizing nozzle, and the air dynamic mixer atomizes glue to the outside through the atomizing nozzle, the compressed air pipeline is used to introduce compressed air, and the reused fluid pipeline is used to introduce adhesive, curing agent solution and paraffin in sequence, and the adhesive, curing agent and paraffin introduced in sequence are mixed with compressed air in the air dynamic mixer to reach a predetermined mixed gas-liquid pressure of 3-5 bar. In the mixed gas-liquid, the adhesive is mixed with water in the curing agent solution, so that the adhesive continues to expand rapidly and is sprayed out from the atomizing nozzle with compressed air as the atomizing carrier. Therefore, the present invention can realize atomizing glue applying without a high-speed micro motor, thereby eliminating the risk of fire or explosion caused by static electricity and short circuit in the gluing process; and adopts a simple pipeline connection structure, which can greatly reduce maintenance and repair costs.

[0016] 2. Because the atomizing glue applying device for OSB and FOSB of the present invention comprises a compressed air pipeline, a glue liquid pipeline, a curing agent pipeline, an air dynamic mixer, an expansion channel and an atomizing nozzle, the compressed air pipeline, the glue liquid pipeline and the curing agent pipeline are all connected to the air dynamic mixer, the air dynamic mixer is connected to the atomizing nozzle through the expansion channel, and the air dynamic mixer is open to the outside through the atomizing nozzle, the compressed air pipeline is used to pass compressed air, the glue liquid pipeline is used to pass adhesive, and the curing agent pipeline is used to pass curing agent solution, the introduced adhesive and curing agent are mixed in the air dynamic mixer. The coupler is mixed with compressed air to reach a predetermined mixed gas-liquid pressure of 3-5 bar. In the mixed gas-liquid, the adhesive is mixed with water in the curing agent solution, causing the adhesive to continue to expand rapidly and use the compressed air as an atomization carrier. After passing through the expansion channel, the adhesive is ejected from the atomizing nozzle, and the instantaneous pressure of the ejection can reach 4-6 bar. Therefore, the utility model can realize atomization gluing without the use of a high-speed micro motor, thereby eliminating the risk of fire or explosion caused by static electricity and short circuit in the gluing process; and adopts a simple pipeline connection structure, which can greatly reduce maintenance and repair costs.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following examples and drawings specifically illustrate the atomizing sizing device for OSB and FOSB of the present invention. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0022] <Example 1>

[0023] like Figure 1 As shown, the atomizing gluing device 100 for OSB and FOSB in this embodiment includes a compressed air pipeline 1, a reuse fluid pipeline 2A, an air dynamic mixer 3 and an atomizing nozzle 5. In this embodiment, the atomizing gluing device 100 for OSB and FOSB is set on the relevant mechanism through a fixed bracket F1.

[0024] The compressed air pipeline 1 and the reused fluid pipeline 2A are both connected to the air dynamic mixer 3, the air dynamic mixer 3 is connected to the atomizing nozzle 5, and the air dynamic mixer 3 is open to the outside through the atomizing nozzle 5. Specifically, the compressed air pipeline 1 is used to introduce compressed air, and the reused fluid pipeline 2A is used to introduce adhesive, curing agent solution and paraffin in sequence, and the adhesive is isocyanate adhesive (MDI) or urea-formaldehyde resin glue (MUF or UF).

[0025] Specifically, one end of the compressed air pipeline 1 is connected to the external air compressor, and the other end is connected to the air dynamic mixer 3; one end of the reused fluid pipeline 2A is connected to the external glue supply device within the first predetermined time after the start of gluing, and the other end is connected to the air dynamic mixer 3; one end of the reused fluid pipeline 2A is connected to the external curing agent solution supply device within the second predetermined time after the first predetermined time, and the other end is connected to the air dynamic mixer 3; one end of the reused fluid pipeline 2A is connected to the external paraffin supply device within the third predetermined time after the second predetermined time, and the other end is connected to the air dynamic mixer 3.

[0026] Thus, isocyanate adhesive or urea-formaldehyde resin adhesive, curing agent solution and paraffin are sequentially introduced into the air dynamic mixer 3 through the reused fluid pipeline 2A, and the compressed air, adhesive solution and paraffin are mixed with each other through the air dynamic mixer 3. In the mixed gas-liquid, the adhesive is mixed with the water in the curing agent solution, so that the adhesive continues to expand rapidly and reaches a predetermined mixed gas-liquid pressure of 3-5 bar. The compressed air is used as an atomization carrier and is sprayed out from the atomizing nozzle 5 to realize atomized gluing.

[0027] The connecting part between the compressed air pipeline 1 and the air dynamic mixer 3 is used as the first connecting part 3a, and the connecting part between the reused fluid pipeline 2A and the air dynamic mixer 3 is used as the second connecting part 3b. The first connecting part 3a has a longer connecting path with the atomizing nozzle 5 than the second connecting part 3b. Specifically, the length of the part of the air dynamic mixer 3 from the first connecting part 3a to the atomizing nozzle 5, and the length of the part of the air dynamic mixer 3 from the second connecting part 3b to the atomizing nozzle 5, these two lengths correspond to the connecting paths between the first connecting part 3a, the second connecting part 3b and the atomizing nozzle 5, respectively.

[0028] <Example 2>

[0029] In the second embodiment, the same symbols are given to the same structures as those in the first embodiment, and the same descriptions are omitted.

[0030] In the second embodiment, the structure of the atomizing glue applying device 100 for OSB and FOSB is different from that of the first embodiment in that:

[0031] like Figure 2 As shown, the OSB and FOSB atomizing glue applying device 100 in the second embodiment does not reuse the fluid pipeline 2A, and has an additional glue pipeline 2B and a curing agent pipeline 2C, as well as an additional expansion channel 4.

[0032] The compressed air pipeline 1 , the glue pipeline 2B and the curing agent pipeline 2C are all connected to the air dynamic mixer 3 , and the air dynamic mixer 3 is connected to the atomizing nozzle 5 through the expansion channel 4 , and the air dynamic mixer 3 atomizes glue to the outside through the atomizing nozzle 5 .

[0033] Specifically, one end of the glue pipe 2B is connected to the external glue supply device, and the other end is connected to the air dynamic mixer 3; one end of the curing agent pipe 2C is connected to the external curing agent solution supply device, and the other end is connected to the air dynamic mixer 3.

[0034] The glue liquid pipeline 2B is used to introduce isocyanate adhesive or urea-formaldehyde resin adhesive into the air dynamic mixer 3, and the curing agent pipeline 2C is used to introduce curing agent solution into the air dynamic mixer 3. Through the air dynamic mixer 3, the compressed air, adhesive and fixative solution introduced into the air dynamic mixer 3 through the compressed air pipeline 1 are mixed with each other to reach a predetermined mixed gas-liquid pressure of 3-5 bar. In the mixed gas-liquid, the adhesive is mixed with the water in the curing agent solution, so that the adhesive continues to expand rapidly, and uses compressed air as an atomization carrier. After passing through the expansion channel 4, it is sprayed out from the atomizing nozzle 5 to realize atomized gluing, and the instantaneous pressure of the spray can reach 4-6 bar.

[0035] The expansion channel 4 is a connecting hose with a length range of 10cm-30cm. Specifically, the air dynamic mixer 3 is a rigid straight tube, and the atomizing nozzle 5 is a rigid element. Therefore, the flexible expansion channel 4 enables the atomizing nozzle 5 to flexibly adjust its relative position relative to the air dynamic mixer 3, that is, the direction of the atomizing nozzle 5 can be flexibly adjusted. In this embodiment, the utility model also includes a posture stabilizing bracket F2. The posture stabilizing bracket F2 is a plastic tube with a bend. One end of the posture stabilizing bracket F2 is fixed on the atomizing nozzle 5, and the other end is fixed on the air dynamic mixer 3. The posture stabilizing bracket F2 is used to temporarily stabilize the relative posture of the air dynamic mixer 3 and the atomizing nozzle 5.

[0036] The connecting part between the glue pipe 2B and the air dynamic mixer 3 is used as the second connecting part 3b, and the connecting part between the curing agent pipe 2C and the air dynamic mixer 3 is used as the third connecting part 3c. The connecting paths between the first connecting part 3a, the second connecting part 3b and the third connecting part 3c and the atomizing nozzle 5 increase sequentially. Specifically, the length from the first connecting part 3a to the connecting end of the air dynamic mixer 3 and the expansion channel 4 plus the total length formed by the expansion channel 4; the length from the second connecting part 3b to the connecting end of the air dynamic mixer 3 and the expansion channel 4 plus the total length formed by the expansion channel 4; the length from the third connecting part 3c to the connecting end of the air dynamic mixer 3 and the expansion channel 4 plus the total length formed by the expansion channel 4; these three total lengths correspond to the connecting paths between the first connecting part 3a, the second connecting part 3b and the third connecting part 3c and the atomizing nozzle 5 respectively.

[0037] The above-mentioned embodiments are preferred cases of the present invention and are not intended to limit the scope of protection of the present invention. Various deformations or modifications that can be made by ordinary technicians in this field without creative work within the scope of the attached claims are still within the scope of protection of this patent.
