Description

Technical Field

[0001] This utility model relates to the field of sandwich panel production, specifically an automatic gluing device for sandwich panel composite machines. Background Technology

[0002] Sandwich panels are a common building material, offering excellent flame retardancy, sound insulation, and environmental friendliness. They consist of two metal panels on the top and bottom, pressed together with a high-polymer insulating core. They are easy to install, lightweight, and environmentally friendly. The closed-cell molecular structure used in the filling system prevents moisture condensation. During production, both sides of the core are coated with adhesive, and then the panels are pressed together using the adhesive.

[0003] The current automatic gluing device for sandwich panel composite machines, as described in patent CN215235455U, includes a base. A bracket and a fixed seat are sequentially fixed to the top of the base by bolts. A sliding seat is slidably mounted on the bracket. A cylinder is fixedly mounted to the top of the sliding seat by bolts. A piston rod is located inside the cylinder, and the end of the piston rod is connected to a mounting seat by a hexagonal screw. A gluing assembly is mounted on the mounting seat. A rotating shaft is rotatably mounted between the base and the fixed seat via a bearing. A gear and a turntable are sequentially fixedly mounted on the outside of the rotating shaft. The gear meshes with a rack, and a sliding plate is welded to the other end of the rack. The sliding plate is slidably mounted on the bracket. A movable striking rod is movably hinged to one side of the turntable.

[0004] Regarding the aforementioned related technologies, the inventors proposed using a cylinder to drive a piston rod, which in turn moves the adhesive application assembly downwards, bringing the adhesive application head closer to and in contact with the sandwich panel. Subsequently, a drive source employing a servo screw assembly is activated, driving a sliding seat to move the adhesive application assembly, applying adhesive along the surface of the sandwich panel. However, this adhesive application method can only apply adhesive to the top surface of the sandwich panel. To apply adhesive to the bottom surface, the sandwich panel must first be flipped over, resulting in relatively low efficiency in applying adhesive to both sides of the sandwich panel.

[0005] The purpose of this invention is to provide an automatic gluing device for a sandwich panel composite machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic gluing device for a sandwich panel composite machine, comprising...

[0007] The conveying mechanism includes a conveying frame, on both sides of the conveying frame symmetrically rotatably connected to conveying rollers. On one side, two sets of conveying rollers are driven to the outer sides of a first conveyor belt, and on the other side, two sets of conveying rollers are driven to the outer sides of a second conveyor belt. Multiple support pins are uniformly fixedly connected to the outer sides of the second conveyor belt. A first stepper motor is symmetrically fixedly connected to one side of the conveying frame, and the output ends of the first stepper motors on both sides are fixedly connected to the conveying rollers on both sides respectively.

[0008] The lower glue-applying mechanism includes a lower glue-applying roller rotatably connected inside the conveyor frame. The bottom of the lower glue-applying roller is provided with a lower glue-applying box fixedly connected to the conveyor frame. A second stepper motor is fixedly connected to one side of the conveyor frame, and the output end of the second stepper motor is fixedly connected to the lower glue-applying roller.

[0009] The glue-applying mechanism includes extension plates symmetrically fixedly connected to both sides of the conveyor frame. Hydraulic rods are symmetrically fixedly inserted through the interior of the extension plates. Beam plates are fixedly connected to the output ends of two sets of hydraulic rods on the same side. A roller frame is fixedly connected between the two sets of beam plates. A glue-applying roller is rotatably connected inside the roller frame. A third stepper motor is fixedly connected to one side of the roller frame. The output end of the third stepper motor is fixedly connected to the glue-applying roller. A glue-applying box is fixedly connected to the top of the roller frame. A pump is fixedly connected to one side of the glue-applying box. A glue-guide pipe is fixedly connected to the output end of the pump. The glue-guide pipe extends to the top of the glue-applying roller.

[0010] As a further embodiment of this utility model: a scraper is fixedly connected to one side of the inner side of the lower glue box, and the scraper corresponds to the lower glue roller.

[0011] As a further embodiment of this utility model: the top of the hydraulic rod is symmetrically and fixedly connected with reinforcing ribs, and each set of reinforcing ribs is fixedly connected to the roller frame.

[0012] As a further embodiment of this utility model: the bottom of the glue guide tube is uniformly and fixedly connected with a plurality of interconnected glue discharge tubes, and each group of glue discharge tubes corresponds to the glue application roller.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] With the above-described structure, when the device is running, the lower glue roller rotates, continuously picking up glue from the lower glue tank. Simultaneously, a pump draws glue from the upper glue tank and delivers it to the glue guide tube. The glue then falls onto the upper glue roller. As the board core passes between the continuously rotating upper and lower glue rollers, its top and bottom surfaces are coated with glue. Afterward, a rotating second conveyor belt and support pins catch and transport the board core. Notably, the support pins effectively reduce the contact area with the bottom surface of the board core, thereby reducing the probability of damaging the glue on the bottom surface. In summary, the entire device can meet the requirement of simultaneous glue coating of the top and bottom surfaces of the board core, thus significantly improving the glue coating efficiency of the board core.

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Please see Figure 1-4An automatic gluing device for a sandwich panel composite machine includes a conveying mechanism 1. The conveying mechanism 1 includes a conveying frame 101. Conveying rollers 103 are symmetrically rotatably connected to both sides of the conveying frame 101. A first conveyor belt 102 is driven to the outer sides of two sets of conveying rollers 103 on one side, so that the rotation of one side's conveying rollers 103 can drive the first conveyor belt 102 to rotate, allowing the first conveyor belt 102 to convey the core panel to be glued. A second conveyor belt 105 is driven to the outer sides of two sets of conveying rollers 103 on the other side. Multiple support pins 106 are evenly fixed to the outer side of the second conveyor belt 105. The second conveyor belt 105 is configured to drive the support pins 106 to move accordingly during rotation, allowing the support pins 106 to support and convey the glued core panel.

[0025] A first stepper motor 104 is symmetrically fixedly connected to one side of the conveyor frame 101. The output ends of the first stepper motors 104 on both sides are fixedly connected to the conveyor rollers 103 on both sides, respectively. The first stepper motors 104 are configured to drive the corresponding conveyor rollers 103 to rotate when the machine starts working. The lower glue coating mechanism 2 includes a lower glue roller 202 rotatably connected inside the conveyor frame 101. The bottom of the lower glue roller 202 is provided with a lower glue box 201 fixedly connected to the conveyor frame 101. The lower glue box 201 is configured to hold glue, so that the lower glue roller 202 can continuously pick up the glue in the lower glue box 201 when it rotates. This allows the lower glue roller 202 to roll glue onto the bottom of the board core when it passes the top of the lower glue roller 202.

[0026] A scraper 204 is fixedly connected to one side of the inner side of the lower glue box 201. The scraper 204 corresponds to the lower glue roller 202. The scraper 204 is used to scrape off excess glue from the outside of the lower glue roller 202 when it rotates. A second stepper motor 203 is fixedly connected to one side of the conveyor frame 101. The output end of the second stepper motor 203 is fixedly connected to the lower glue roller 202. The second stepper motor 203 is used to drive the lower glue roller 202 to rotate when the machine starts working. The upper glue coating mechanism 3 includes extension plates 301 symmetrically fixedly connected to both sides of the conveyor frame 101. Hydraulic rods 302 are symmetrically fixed through the interior of the extension plates 301. The extension plates 301 are used to support the hydraulic rods 302.

[0027] Two sets of hydraulic rods 302 on the same side are fixedly connected to beam plates 303 at their output ends. A roller frame 304 is fixedly connected between the two sets of beam plates 303. Reinforcing ribs 310 are symmetrically fixedly connected to the top of the hydraulic rods 302. Each set of reinforcing ribs 310 is fixedly connected to the roller frame 304. The reinforcing ribs 310 are used to further connect and fix the roller frame 304 and the beam plates 303. An upper glue roller 305 is rotatably connected inside the roller frame 304. The hydraulic rods 302 are used to drive the beam plates 303, roller frame 304 and upper glue roller 305 to move up and down when starting work, so as to adjust the distance between the upper glue roller 305 and the lower glue roller 202, thereby meeting the requirements for applying glue to cores of different thicknesses.

[0028] A third stepper motor 311 is fixedly connected to one side of the roller frame 304. The output end of the third stepper motor 311 is fixedly connected to the glue-applying roller 305. The third stepper motor 311 is configured to drive the glue-applying roller 305 to rotate during startup. A glue-applying tank 306 is fixedly connected to the top of the roller frame 304. The glue-applying tank 306 is configured to hold glue. A pump 307 is fixedly connected to one side of the glue-applying tank 306. A glue-guide tube 308 is fixedly connected to the output end of the pump 307. The glue-guide tube 308 extends to the top of the glue-applying roller 305. The pump 307 is configured to draw glue from inside the glue-applying tank 306 into the glue-guide tube 308 during startup.

[0029] Multiple interconnected glue discharge pipes 309 are evenly fixedly connected to the bottom of the glue guide tube 308. Each set of glue discharge pipes 309 corresponds to the glue application roller 305. The glue discharge pipes 309 are designed to evenly discharge the glue inside the glue guide tube 308 to the top of the glue application roller 305, allowing the continuously rotating glue application roller 305 to apply glue to the top of the core board. Fixed plates 312 are fixedly connected to the bottom of both sets of beam plates 303. A glue scraper box 313 is fixedly connected between the fixed plates 312. One side of the glue scraper box 313 corresponds to the glue application roller 305. The glue scraper box 313 is used to scrape away and collect excess glue from the outside of the glue application roller 305. A connecting guide pipe 314 is fixedly connected to one side of the bottom of the glue scraper box 313. The guide pipe 314 extends into the interior of the lower glue tank 201. The guide pipe 314 is used to guide the glue inside the glue scraper box 313 into the interior of the lower glue tank 201, thereby realizing the recycling and reuse of the glue.

[0030] In use, glue is poured into the upper glue tank 306 and the lower glue tank 201. Then, the hydraulic rod 302 is activated, causing the hydraulic rod 302 to drive the beam plate 303, roller frame 304, and upper glue roller 305 downwards until the distance between the upper glue roller 305 and the lower glue roller 202 is adjusted to match the thickness of the core of the board to be glued. Then, the second stepper motor 203, the third stepper motor 311, and two sets of first stepper motors 104 are activated. When the two sets of first stepper motors 104 are activated, they can respectively drive the two side conveyor rollers 103, the first conveyor belt 102, and the second conveyor belt 105 to rotate. When the second stepper motor 203 is activated, it can drive the lower glue roller 202 to rotate, allowing the lower glue roller 202 to continuously pick up the glue inside the lower glue tank 201. When the third stepper motor 311 is activated, it can drive the upper glue roller 305 to rotate. Then, the core of the board to be glued is... The glued core is placed on top of the first conveyor belt 102, allowing the first conveyor belt 102 to transport the core to one side of the second conveyor belt 105. The pump 307 is activated, drawing glue from the glue tank 306 into the glue guide tube 308. Then, the glue is discharged to the outside of the glue roller 305 through each set of glue discharge tubes 309. As the glue roller 305 rotates, the glue scraper box 313 scrapes away excess glue from the outside of the glue roller 305 and scrapes it evenly. When the core is conveyed between the glue roller 305 and the lower glue roller 202, the rotating lower glue roller 202 and the glue roller 305 can roll the glue onto the bottom and top surfaces of the core, respectively. Then, it is received and transported by the continuously rotating second conveyor belt 105 and the support pin 106. The support pin 106 can effectively reduce the contact area with the bottom surface of the core, thereby reducing damage to the glue on the bottom surface of the core.
