Description

Technical Field

[0001] The invention relates to the technical field of adhesive preparation, and in particular to a device for preparing a biomass adhesive for particleboard. Background Art

[0002] Particleboard, also known as particle board, is a kind of man-made board made by cutting various branches, small-diameter wood, fast-growing wood, sawdust, etc. into pieces of a certain size, drying them, mixing them with glue, hardener, waterproofing agent, etc., and pressing them under a certain temperature and pressure. In the production process of particleboard, adhesives need to be added to bond them together and then pressed into shape.

[0003] At present, adhesives are generally prepared by using a glue mixer to evenly mix various liquid materials and granular materials. However, the current stirring positions are fixed, which makes it inconvenient to stir the adhesives in different directions and positions, so that the adhesives need to spend more time during the stirring process. In addition, the current glue mixers do not have the ability to remove bubbles. When the adhesives are mixed and stirred, air is easily mixed into the materials, resulting in bubbles containing oxygen in the adhesives. Oxidation reactions are easily caused during the storage of the adhesives, resulting in aging of the adhesives and affecting the storage life of the adhesives. Summary of the invention

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Referring to Figure 1 - Fig.10 , a biomass adhesive preparation device for particleboard, comprising a mixing box 1, and a sealing cover 2 is connected to the upper end of the mixing box 1 through a plurality of bolts.

[0023] Mixing mechanism, the mixing mechanism includes a first plate 3 fixedly connected above the inner wall of the mixing box 1, and two sliding columns 4 are fixedly connected to the side wall of the first plate 3 (as shown in Figure 6 ), and a second plate 5 is slidably connected to the side walls of the two sliding columns 4 (as shown in Figure 6As shown, the first plate 3 has a first rod 6 rotatably connected to the lower end, the second plate 5 has a second rod 7 rotatably connected to the lower end, the first rod 6 and the second rod 7 are fixedly connected to the lower side walls of the L-shaped rod 15, and the side walls of the L-shaped rod 15 are fixedly connected to multiple stirring rods 16 (as shown in FIG. Figure 2 and Figure 3 As shown), a third rod 9 is fixedly connected to the top of the side wall of the first rod 6 through a first connecting plate 8, a first gear 10 is fixedly connected to the top of the side wall of the third rod 9, a fourth rod 12 is fixedly connected to the side wall of the second rod 7 through a second connecting plate 11, a second gear 13 is fixedly connected to the side wall of the fourth rod 12, the first gear 10 and the second gear 13 are meshed, and a movable plate 14 is connected to the top of the side walls of the third rod 9 and the fourth rod 12 for common rotation.

[0024] A motor 17 is fixedly connected to the side wall of the mixing box 1 , a first bevel gear 18 is fixedly connected to the movable end of the motor 17 , and a second bevel gear 19 meshing with the first bevel gear 18 is fixedly connected to the side wall of the first rod 6 .

[0025] During the rotation of the motor 17, the first rod 6 is driven to rotate through the first bevel gear 18 and the second bevel gear 19, and then the first rod 6 drives the third rod 9 to rotate along the axis of the first rod 6 through the first connecting plate 8, driving the first gear 10 to rotate. Since the first gear 10 and the second gear 13 are meshed, during the rotation of the first gear 10, under the limiting effect of the moving plate 14, the second gear 13 is driven to rotate in a direction away from or close to the first rod 6 and also swings left and right (such as Figure 3 As shown in the figure, the second rod 7 is driven to move away from or close to the first rod 6 and rotate at the same time, thereby driving the multiple stirring rods 16 located on the two L-shaped rods 15 to move and rotate, stirring the adhesive in different directions and positions, thereby reducing the time required for the adhesive to be stirred.

[0026] The moving plate 14 is provided with a feeding mechanism for slowly adding granular materials. The feeding mechanism includes a feeding box 20 which is fixedly connected to the side wall of the moving plate 14. The discharge port of the feeding box 20 is located between the first gear 10 and the second gear 13 (such as Figure 3 As shown), a fifth rod 21 is rotatably connected to the lower inner wall of the feeding box 20, and a conveying column 22 is fixedly connected to the side wall of the fifth rod 21 located in the feeding box 20. The side wall of the conveying column 22 is provided with two symmetrically arranged grooves 23.

[0027] The end of the movable plate 14 away from the fourth rod 12 is rotatably connected to the sixth rod 24, the lower end of the sixth rod 24 is fixedly connected to the third gear 25 meshing with the first gear 10, the upper end of the sixth rod 24 is fixedly connected to the third bevel gear 26, and the end of the fifth rod 21 away from the charging box 20 is fixedly connected to the fourth bevel gear 27 meshing with the third bevel gear 26.

[0028] During the movement, the movable plate 14 drives the feeding box 20 to move synchronously, so that the granular material coming out of the feeding box 20 can always be ground by the rotating first gear 10 and the second gear 13. At the same time, during the rotation of the first gear 10, the fifth rod 21 will be driven to rotate through the third gear 25, the sixth rod 24, the third bevel gear 26 and the fourth bevel gear 27, and the conveying column 22 will be driven to rotate, so that the two grooves 23 can alternately face the discharge port of the feeding box 20, and then the granular material in the feeding box 20 is intermittently conveyed, avoiding the one-time conveying of the granular material, which causes the granular material to pile up and is inconvenient to mix and stir evenly.

[0029] It should be noted that the transmission ratio between the third bevel gear 26 and the fourth bevel gear 27 is greater than 5:1, so that the third bevel gear 26 can drive the fourth bevel gear 27 to rotate slowly during the rotation process, so as to slowly transport the particulate material.

[0030] The mixing box 1 has two arc grooves 28 (such as Figure 5 As shown in the figure, a bearing plate 30 is connected to the lower part of the inner wall of the mixing box 1 through a cross bar 29 for sealing rotation, and the side wall of the bearing plate 30 is connected to the inner wall of the two arc-shaped grooves 28 for sealing sliding. The lower parts of the inner walls of the two arc-shaped grooves 28 are fixedly connected to limit plates 31, and a feeding pipe 38 is fixedly connected to the upper part of the inner wall of the mixing box 1. A discharge pipe 39 is fixedly connected to the inner wall of the mixing box 1 near the limit plate 31, and electric butterfly valves are provided in the feeding pipe 38 and the discharge pipe 39.

[0031] It should be noted that after the electric butterfly valve is installed on the inner wall of the discharge pipe 39, the side wall of the electric butterfly valve and the inner wall of the arc groove 28 are on the same arc surface, which prevents some adhesive from remaining in the discharge pipe 39 and flowing out to the bottom of the mixing box 1 during the rotation of the supporting plate 30.

[0032] The inner wall of the mixing box 1 facing the second plate 5 is sealed and slidably connected with a C-shaped rod 32, and the two ends of the C-shaped rod 32 located outside the mixing box 1 are fixedly connected with a fixed plate 33. The side wall of the fixed plate 33 is elastically connected to the side wall of the mixing box 1 through a plurality of first springs 34. The lower end of the fixed plate 33 is fixedly connected with a threaded cylinder 36 through a vertical plate 35. The inner wall of the threaded cylinder 36 is threadedly connected with a rifle rod 37. One end of the cross bar 29 penetrates the inner wall of the mixing box 1 and is fixedly connected to one end of the rifle rod 37.

[0033] like Figure 6 As shown, in the initial position, the C-shaped rod 32 is arranged away from the second plate 5. Then, when the second plate 5 moves to the farthest point in the direction away from the first plate 3, the second plate 5 will squeeze the C-shaped rod 32 and the fixed plate 33 to move outward. At this time, the fixed plate 33 drives the threaded cylinder 36 to move out of the mixing box 1 through the vertical plate 35. At this time, the threaded cylinder 36 drives the carrying plate 30 to rotate clockwise through the rifle rod 37 and the cross bar 29 (as shown in FIG. Figure 2As shown in FIG. 1 , when the second plate 5 moves toward the first plate 3, the elastic force of the plurality of first springs 34 drives the U-shaped rod 32 and the fixed plate 33 to move into the mixing box 1. At this time, the threaded cylinder 36 drives the carrying plate 30 to rotate counterclockwise (as shown in FIG. 1 ) through the rifle rod 37 and the cross bar 29. Figure 2 As shown in the figure, and during the rotation of the supporting plate 30, its side wall will not separate from the inner side walls of the two arc-shaped grooves 28. In this way, during the movement of the second plate 5 away from and close to the first plate 3, the cross bar 29 will drive the supporting plate 30 to rotate intermittently clockwise and counterclockwise, continuously tilting the material above the supporting plate 30, thereby accelerating the mixing of the material above the supporting plate 30.

[0034] An air suction frame 40 is fixedly connected to the bottom of the mixing box 1, and a slide plate 41 is sealingly and slidably connected to the inner wall of the air suction frame 40. The lower part of the inner wall of the air suction frame 40 is connected to the upper part of the inner wall of the mixing box 1 through a one-way air suction pipe 43, and the lower part of the inner wall of the air suction frame 40 is connected to the lower part of the inner wall of the mixing box 1 through a one-way air outlet pipe 44. The lower part of the inner wall of the air suction frame 40 is connected to the lower part of the inner wall of the mixing box 1 through a ventilation pipe 45, and the lower end of the supporting plate 30 is rotatably connected to the upper end of the slide plate 41 through a pressing plate 42.

[0035] A vacuum sensor 46 is fixedly connected to the upper inner wall of the mixing box 1, a first solenoid valve is provided in the one-way suction pipe 43, a second solenoid valve is provided in the ventilation pipe 45, the vacuum sensor 46 and the first solenoid valve are connected to an external control mechanism, and the vacuum sensor 46 and the second solenoid valve are connected to an external control mechanism.

[0036] The vacuum sensor 46 can detect the pressure in the space above the supporting plate 30 of the mixing box 1. It is a prior art. When the pressure in the space is greater than the set value of the vacuum sensor 46, the first solenoid valve is powered on and opened, and the second solenoid valve is powered off and closed. When the pressure in the space is less than the set value of the vacuum sensor 46, the first solenoid valve is powered off and closed, and the second solenoid valve is powered on and opened.

[0037] When the pressure in the space above the mixing box 1 and the supporting plate 30 is greater than the set value of the vacuum sensor 46, the first solenoid valve is powered off and closed, the second solenoid valve is powered on and opened, and then the one-way suction pipe 43 is opened and the ventilation pipe 45 is closed. During the rotation of the supporting plate 30, the sliding plate 41 is driven by the pressure plate 42 to slide up and down on the inner wall of the suction frame 40. At this time, the suction frame 40 can continuously extract the gas in the mixing box 1 through the one-way suction pipe 43 and the one-way exhaust pipe 44, so that the mixing box 1 is in a vacuum state, avoiding the prior art that the adhesive is prone to contain bubbles containing oxygen during the preparation process, and oxidation reactions are prone to occur during the storage of the adhesive, resulting in aging of the adhesive and affecting the storage life of the adhesive.

[0038] When the pressure in the space above the mixing box 1 and the supporting plate 30 is less than the set value of the vacuum sensor 46, the first solenoid valve is powered off and closed, and the second solenoid valve is powered on and opened, and then the one-way suction pipe 43 is closed and the ventilation pipe 45 is opened. At this time, the suction frame 40 can freely inhale air from the outside without hindering the rotation of the supporting plate 30.

[0039] like Figure 7 As shown, a plurality of T-shaped rods 47 are slidably connected through the side wall of the second plate 5, a pin 48 is fixedly connected to the lower end of the T-shaped rod 47, the upper end of the second plate 5 is elastically connected to the upper side wall of the T-shaped rod 47 through a second spring 49, an arch plate 51 is fixedly connected to the lower end of the second gear 13, and a rolling ball 50 that cooperates with the arch plate 51 is rotatably connected to the upper end of the T-shaped rod 47.

[0040] When the second gear 13 rotates in a direction away from or close to the first rod 6 and swings left and right, the arch plate 51 will intermittently squeeze the multiple balls 50. At this time, the balls 50 are squeezed by the arch plate 51 and the elastic force of the second spring 49. At this time, the T-shaped rod 47 will drive the pin 48 to move up and down, bursting any bubbles that may exist on the upper surface of the material, thereby increasing the vacuum effect in the mixing box 1.

[0041] In the process of preparing the adhesive, the liquid material is first added to the mixing box 1 through the feeding pipe 38, and then the electric butterfly valve located in the feeding pipe 38 is closed, and then the granular material is added to the feeding box 20, and finally the sealing cover 2 and the mixing box 1 are sealed and connected by multiple bolts; The driving motor 17 rotates, and then drives the first rod 6 to rotate through the first bevel gear 18 and the second bevel gear 19, and then the first rod 6 drives the third rod 9 to rotate along the axis of the first rod 6 through the first connecting plate 8, and drives the first gear 10 to rotate. Since the first gear 10 and the second gear 13 are meshed, during the rotation of the first gear 10, under the action of the moving plate 14, the second gear 13 is driven to rotate in a direction away from or close to the first rod 6 and also swings left and right (such as Figure 3 As shown in the figure, the second rod 7 is driven to move away from or close to the first rod 6 and rotate at the same time, thereby driving the multiple stirring rods 16 located on the two L-shaped rods 15 to move and rotate, stirring the adhesive in different directions and positions, thereby reducing the time required for the adhesive to be stirred; At the same time, the moving plate 14 drives the feeding box 20 to move synchronously during the movement, so that the granular materials coming out of the feeding box 20 can always be ground by the rotating first gear 10 and the second gear 13. At the same time, during the rotation of the first gear 10, the fifth rod 21 is driven to rotate through the third gear 25, the sixth rod 24, the third bevel gear 26 and the fourth bevel gear 27, and the conveying column 22 is driven to rotate, so that the two grooves 23 can alternately face the discharge port of the feeding box 20, and then the granular materials in the feeding box 20 are intermittently conveyed, avoiding the one-time conveying of the granular materials, which causes the granular materials to pile up and inconvenience in mixing and stirring them evenly; When the second plate 5 moves to the farthest point away from the first plate 3, the second plate 5 squeezes the U-shaped rod 32 and the fixed plate 33 to move outward. At this time, the fixed plate 33 drives the threaded cylinder 36 to move out of the mixing box 1 through the vertical plate 35. At this time, the threaded cylinder 36 drives the carrying plate 30 to rotate clockwise through the rifle rod 37 and the cross bar 29 (such as Figure 2 As shown in FIG. 1 , when the second plate 5 moves toward the first plate 3, the elastic force of the plurality of first springs 34 drives the U-shaped rod 32 and the fixed plate 33 to move into the mixing box 1. At this time, the threaded cylinder 36 drives the carrying plate 30 to rotate counterclockwise (as shown in FIG. 1 ) through the rifle rod 37 and the cross bar 29. Figure 2 As shown in the figure, and during the rotation of the carrying plate 30, its side wall will not separate from the inner side walls of the two arc-shaped grooves 28, so that during the movement of the second plate 5 away from and close to the first plate 3, the cross bar 29 will drive the carrying plate 30 to rotate intermittently clockwise and counterclockwise, and the material above the carrying plate 30 will be continuously tilted and moved, thereby accelerating the mixing of the material above the carrying plate 30; At the beginning, when the pressure in the space above the supporting plate 30 of the mixing box 1 is greater than the set value of the vacuum sensor 46, the first solenoid valve is powered off and closed, the second solenoid valve is powered on and opened, and then the one-way suction pipe 43 is opened, and the ventilation pipe 45 is closed. During the rotation of the supporting plate 30, the sliding plate 41 will be driven by the pressure plate 42 to slide up and down on the inner wall of the suction frame 40. At this time, the suction frame 40 can continuously extract the gas in the mixing box 1 through the one-way suction pipe 43 and the one-way exhaust pipe 44, so that the mixing box 1 is in a vacuum state, avoiding the prior art that the adhesive is prone to contain bubbles containing oxygen during the preparation process, and oxidation reactions are prone to occur during the storage of the adhesive, resulting in aging of the adhesive and affecting the storage life of the adhesive.

[0042] When the pressure in the space above the carrier plate 30 of the mixing box 1 is less than the set value of the vacuum sensor 46, the first solenoid valve is powered off and closed, and the second solenoid valve is powered on and opened, and then the one-way air suction pipe 43 is closed and the vent pipe 45 is opened. At this time, the air suction frame 40 can freely suck air from the outside without hindering the rotation of the carrier plate 30. When the second gear 13 rotates away from or close to the first rod 6 and swings left and right, the arch plate 51 will intermittently squeeze the multiple balls 50. At this time, the balls 50 are squeezed by the arch plate 51 and the elastic force of the second spring 49. At this time, the T-shaped rod 47 will drive the pin 48 to move up and down, puncturing the bubbles that may exist on the upper surface of the material, thereby increasing the vacuum effect in the mixing box 1; After the adhesive is prepared, the carrier plate 30 is in the initial position (eg Figure 5 As shown), then open the electric butterfly valve in the discharge pipe 39 to discharge the adhesive.

[0043] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto.
