Description

Technical Field

[0001] The invention relates to the technical field of lightweight building material spraying, and in particular to a mixed spraying device for lightweight building materials. Background Art

[0002] Lightweight building materials are a new type of composite material, usually with alkali-resistant glass fiber as a reinforcing material, sulphoaluminate low-alkalinity cement as a gelling material, and appropriate aggregates as a base material, and are made through processes such as spraying, vertical mold casting, extrusion, and slurry flow. This type of material is characterized by low density and light weight, and has good strength, heat insulation, sound insulation, fire resistance and other properties, so it is widely used in the construction industry. In order to improve the comprehensive performance of lightweight building materials, it is usually necessary to mix a variety of specific coatings and then spray them during the production process.

[0003] The Chinese patent application number CN202110650359.3 discloses a mixing spraying device for manufacturing lightweight building materials. By setting a clamping mechanism, a flipping mechanism, a stirring mechanism and a feeding mechanism, through the cooperation between the structures, the mixing box after spraying can be replenished with liquid and then stirred and mixed. At the same time, the building board can be driven to rotate 180 degrees, so that the other side of the building board can be sprayed the next time, thereby achieving the effect of spraying paint on both sides of the building board. However, this technical solution still has the following defects:

[0004] 1. During the clamping process, the main plywood needs to be moved to both sides, and then the building board is placed between the two main plywoods.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-10 As shown, the present invention is a mixing spraying device for lightweight building materials, including a conveyor 1 and a mixing box 2. The conveyor 1 conveys a building board 3, which is a prior art and will not be described in detail. A clamping mechanism 4 for clamping the building board 3 is arranged near one end of the conveyor 1. The clamping mechanism 4 includes a moving frame 41, an elastic clamping member 42, a support member 43, a push mechanism 44 and a linkage mechanism 45. Two moving frames 41 are symmetrically distributed on both sides of the conveyor 1. Two elastic clamping members 42 are symmetrically arranged between the two moving frames 41. The support member 43 is arranged between the two moving frames 41. 43 is slidably installed on one side of the elastic clamping member 42, and the support member 43 is connected to the elastic clamping member 42 through a linkage mechanism 45. The push mechanism 44 is installed on the movable frame 41. The push mechanism 44 is used to press the elastic clamping member 42, and when pressing, the support member 43 is driven to slide into the elastic clamping member 42 through the linkage mechanism 45. The mixing box 2 is located below the pressing mechanism 4, and a spraying mechanism 5 is installed on the mixing box 2. A mixing component 6 is installed between the pressing mechanism 4 and the mixing box 2. A driving mechanism 7 for controlling the movement of the pressing mechanism 4 is installed on the conveyor 1.

[0036] It should be noted that, when in use, the conveyor 1 conveys the building board 3 to be sprayed. When it moves to the discharge end of the conveyor, the building board 3 will pressurize the two elastic clamping members 42 to make them slide back to each other adaptively. The support members 43 can be used to support the building board 3 between the elastic clamping members 42 to prevent it from falling. When the building board 3 moves to a suitable position, the conveyor 1 pauses, and the horizontal push mechanism 44 is started to pressurize the elastic clamping members 42 to stably clamp the building board 3. When the horizontal push mechanism 44 is started, it cooperates with the linkage mechanism 45 to drive the support member 43 to slide into the elastic clamping member 42, so that it no longer contacts the bottom of the building board 3, which is convenient for the subsequent simultaneous spraying of both sides of the building board 3 without obstruction;

[0037] After the building board 3 is clamped, the driving mechanism 7 can be started to drive it to move back and forth. During the movement, the mixing component 6 is used to fully mix the various coatings in the mixing box 2. Finally, the mixing component 6 is used to spray both sides of the reciprocating building board 3 simultaneously. After spraying, it can be dried with external drying equipment, and then the finished building board 3 is removed, the conveyor 1 is started, and the previous operation is repeated to spray the subsequent building board 3.

[0038] like Figure 2 and Figure 5-6 As shown, the elastic clamping member 42 includes an arc plate 421, a clamping plate 422, a sliding rod 423, a first spring 424 and a limit block 425. The arc plate 421 is connected to one end of the clamping plate 422 close to the conveyor 1, and the limit block 425 is installed on one side of the clamping plate 422 close to the end, which is used to limit the position of the building board 3. Two sliding rods 423 are symmetrically installed on one side of the clamping plate 422 close to the movable frame 41, and the sliding rod 423 slides through the movable frame 41. The first spring 424 is sleeved on the sliding rod 423, and the two ends of the first spring 424 are respectively connected to the movable frame 41 and the clamping plate 422.

[0039] It should be noted that during the conveying process of the building board 3, one end thereof first enters between the two curved plates 421. As the subsequent building board 3 continues to move forward, pressure will be applied to the curved surface of the curved plate 421, so that the two curved plates 421 can adaptively slide back to back. Then the building board 3 can smoothly move between the two clamps 422. The reaction force of the first spring 424 can enable the clamps 422 to adaptively elastically clamp the building board 3. When the end of the building board 3 moves to the position of the limit block 425, the conveyor 1 is suspended. In this embodiment, a touch-pressure switch can be installed on the limit block 425. When the end of the building board 3 contacts the touch-pressure switch on the limit block 425, the conveyor 1 can be linked to suspend its operation.

[0040] like Figure 3 and Figure 5-7As shown, the support member 43 includes a strip convex plate 431, a T-shaped plate 432 and a second spring 433. A groove for sliding the strip convex plate 431 is provided on the side of the clamping plate 422 away from the movable frame 41. The T-shaped plate 432 slides through the bottom of the groove, and the T-shaped plate 432 is connected to the strip convex plate 431. Two second springs 433 are symmetrically connected on one side of the T-shaped plate 432 close to the clamping plate 422, and the other end of the second spring 433 is connected to the clamping plate 422.

[0041] It should be noted that, due to the elastic clamping member 42 (such as Figure 4 As shown in the figure, the clamping force of the building board 3 is limited. In order to prevent the building board 3 from falling when moving, the strip convex plate 431 can be used to support the bottom of the building board 3 when moving along the clamping plate 422. However, the strip convex plate 431 will partially block the bottom of the building board 3, which will make it impossible to spray it completely. Therefore, the strip convex plate 431 is designed as a sliding structure, and when spraying is performed subsequently, the strip convex plate 43 only needs to be put into the groove.

[0042] like Figure 4-5 As shown, the push mechanism 44 includes a hydraulic cylinder 441, a pressure plate 442 and a cross column 443. The two pressure plates 442 are arranged between the moving frame 41 and the clamping plate 422. The cross column 443 is connected between the two pressure plates 442. The hydraulic cylinder 441 is installed on one side of the moving frame 41, and the piston rod of the hydraulic cylinder 441 passes through the moving frame 41 and is connected to the cross column 443.

[0043] It should be noted that when it is necessary to stably clamp the building board 3, starting the hydraulic cylinder 441 can push the cross column 443 and the pressure plate 442 toward the clamping plate 422 until the thrust generated by the hydraulic cylinder 441 cooperates with the pressure plate 442 to press against the clamping plate 422. At this time, the pressure conduction will cause the clamping plate 422 to press the two side edges of the building board 3, thereby achieving stable clamping of the building board 3.

[0044] like Figure 5-7 As shown, the linkage mechanism 45 includes a guide sleeve 451, a wedge plate 452 and a connecting rod 453. The guide sleeve 451 is installed on the side of the clamping plate 422 close to the movable frame 41. The wedge plate 452 is slidably plugged with the guide sleeve 451, and the side of the wedge plate 452 close to the top is provided with an inclined portion corresponding to the horizontal push mechanism 44. The two connecting rods 453 are symmetrically hinged to the top of the T-shaped plate 432, and the other end of the connecting rod 453 is hinged to the bottom of the wedge plate 452.

[0045] It should be noted that the inclined portion of the wedge plate 452 near the top corresponds to the position of the cross column 443. When the hydraulic cylinder 441 pushes the cross column 443 to move, the cross column 443 will squeeze the inclined portion of the wedge plate 452, so that the wedge plate 452 slides down along the guide sleeve 451. During the sliding process, the hinged connecting rod 453 can push the T-shaped plate 432 to slide and stretch the second spring 433. The T-shaped plate 432 drives the strip convex plate 431 to slide synchronously, so that the strip convex plate 431 can be received into the groove. That is to say, when the building board 3 is stably clamped, the strip convex plate 431 slides into the groove and separates from the bottom of the building board 3.

[0046] like Figure 1 and Figure 3 As shown, the driving mechanism 7 includes a servo motor 71, a screw 72, a U-shaped slide 73, a sleeve 74 and a connecting arm 75. The two sleeves 74 are symmetrically arranged on both sides of the conveyor 1. The movable frame 41 is slidably plugged into the sleeve 74. The U-shaped slide 73 is slidably arranged at the bottom of the conveyor 1, and the U-shaped slide 73 is connected to the end of the movable frame 41 through the connecting arm 75. The servo motor 71 is installed below the conveyor 1, and the output shaft of the servo motor 71 is coaxially connected to the screw 72, and the U-shaped slide 73 is threadedly connected to the screw 72.

[0047] It should be noted that starting the servo motor 71 drives the screw rod 72 to rotate. The rotation direction and number of revolutions of the servo motor 71 can be controlled by a controller and an encoder. This is a prior art and will not be elaborated on here. When the screw rod 72 rotates, it drives the U-shaped slide 73 to slide along the length direction of the conveyor 1. The U-shaped slide 73 can drive the moving frame 41 to slide stably along the sliding sleeve 74 through the connecting arm 75. The travel direction and stroke of the moving frame 41 can be controlled by controlling the rotation direction and number of revolutions of the servo motor 71. When the moving frame 41 moves, it will drive the stably clamped building board 3 to move synchronously.

[0048] like Figure 1 and Figure 8 As shown, the mixing assembly 6 includes a rotating rod 61, a stirring member 62, a gear 63 and a rack 64. The two racks 64 are respectively installed at the bottom of the two movable frames 41. The two rotating rods 61 are symmetrically installed in the mixing box 2. Multiple groups of stirring members 62 are installed on the rod wall of the rotating rod 61. The top of the rotating rod 61 passes through the top of the mixing box 2 and is connected to the gear 63. The gear 63 is meshed with the corresponding rack 64, and the two gears 63 are arranged between the two racks 64.

[0049] It should be noted that when the two moving frames 41 drive the two racks 64 to move back and forth synchronously, the racks 64 will drive the corresponding gears 63 to drive the rotating rod 61 to rotate. Since the two gears 63 are symmetrically distributed between the two racks 64, when the two racks 64 move in the same direction, the two gears 64 will rotate synchronously in opposite directions, so that the two rotating rods 61 drive the stirring elements 62 to stir synchronously in opposite directions in the mixing box 2. The opposite stirring directions of the two can cause the two stirred paints to collide with each other, which is beneficial to improving the mixing effect. At the same time, since the racks 64 reciprocate back and forth, the stirring direction of the corresponding rotating rod 61 can be intermittently changed, which can further improve the mixing effect.

[0050] like Figure 1 and Fig. 9 As shown, the spraying mechanism 5 includes a delivery pump 51, a delivery pipe 52, an electric slider 53, a guide rail 54, a nozzle 55 and a U-shaped spraying plate 56. The U-shaped spraying plate 56 is located at one end of the clamping mechanism 4 away from the conveyor 1. The guide rail 54 is installed on the top of the mixing box 2. The U-shaped spraying plate 56 is slidably connected to the guide rail 54 through the electric slider 53. The delivery pump 51 is installed on the outer wall of the mixing box 2 near the bottom end. The delivery pump 51 delivers the spray material in the mixing box 2 to the U-shaped spraying plate 56 through the delivery pipe 52. A plurality of nozzles 55 are respectively installed on the opposite side walls of the U-shaped spraying plate 56.

[0051] It should be noted that, when the various coatings in the mixing box 2 are fully mixed, the delivery pump 51 can be started to extract the evenly mixed coatings, and the coatings can be delivered to the U-shaped spray plate 56 in conjunction with the delivery pipe 52. In this embodiment, the size design of the U-shaped spray plate 56 will not cause obstruction to the moving clamping mechanism 4. The interior of the U-shaped spray plate 56 is a hollow structure. When the mixed coating enters its inner cavity, it is sprayed out by multiple nozzles 55 distributed in opposite directions, so that the upper and lower surfaces of the building board 3 can be sprayed synchronously at the same time. Since there is a certain distance between adjacent nozzles 55, in order to ensure more uniform spraying, the position of the U-shaped spray plate 56 can be adjusted by controlling the electric slider 53 to slide along the guide rail 54, thereby facilitating the simultaneous and comprehensive and uniform spraying of both sides of the building board 3.

[0052] like Figure 2 and Figure 8 As shown, multiple groups of stirring elements 62 are distributed axially along the rotating rod 61 located inside the mixing box 2. The stirring elements 62 are composed of multiple stirring paddles distributed circumferentially along the rod wall of the rotating rod 61, and multiple evenly distributed through holes 621 are opened through the stirring paddles. A feed port 21 is installed on the top of the mixing box 2.

[0053] It should be noted that, since the stirring paddle will encounter resistance when stirring the paint, a plurality of through holes 621 are provided so that part of the paint can pass through the through holes 621 during the stirring process, thereby helping to reduce the resistance encountered by the stirring paddle and making it less likely to deform. In this embodiment, the number and specific positions of the feed ports 21 on the top of the mixing box 2 are not limited. The required number of feed ports 21 can be set at appropriate positions according to actual needs, and the feed ports 21 can be used to facilitate the addition of a variety of paints that need to be mixed into the mixing box 2.

[0054] like Figure 1 and Fig.10 As shown, the conveyor 1 is provided with a guide mechanism 8 for preventing the building board 3 from shifting, and the guide mechanism 8 includes a baffle 81, a threaded sleeve 82, an adjusting screw 83 and a bearing seat 84. The bottoms of the two symmetrically arranged baffles 81 are each provided with an arc-shaped opening corresponding to the roller of the conveyor 1, the threaded sleeve 82 is installed on the top of the baffle 81, and the bearing seat 84 is installed on the top of the conveyor 1. The adjusting screw 83 is provided with two threads with opposite thread directions, and one end of the adjusting screw 83 is rotatably connected to the bearing seat 84, and the threaded sleeve 82 is threadedly connected to the adjusting screw 83.

[0055] It should be noted that the baffle 81 utilizes the arc-shaped opening at its bottom not only to enable it to move along the axial direction of the roller on the conveyor 1, but also to facilitate limiting the rotational freedom of the baffle 81. When the adjusting screw 83 with opposite threads is rotated, the two baffles 81 can be driven to slide toward or away from each other, thereby facilitating adaptation to building panels 3 of different widths so that they will not be positionally shifted when moving along the conveyor 1, which is beneficial for smoothly guiding the building panels 3 to be sprayed to the clamping mechanism 4.

[0056] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
