Description

Technical Field

[0001] This invention relates to the field of adhesive coating equipment technology, and in particular to an automatic adhesive coating equipment and method for the production of thermal insulation sandwich panels. Background Technology

[0002] Sandwich panels consist of two layers of molded metal or other material panels and a foamed, cured polymer insulation core sandwiched between the panels. These finished sandwich panels are easy to install, lightweight, and highly efficient. The filling system also uses a closed-cell molecular structure to prevent moisture condensation. The outer steel plate is molded with structural and strength requirements in mind, while also considering aesthetics; the inner layer is flat to accommodate various needs. Sandwich panels are a common building material, offering excellent flame retardancy and sound insulation, and are also environmentally friendly and efficient. During the sandwich panel composite machining process, adhesive is applied to the core surface using gluing equipment before the panels are bonded together.

[0003] Existing adhesive application equipment generally includes two methods: roller coating and spray coating. Compared with the spray coating process, roller coating is slower, and uneven roller pressure or improper operation can lead to inconsistent adhesive layer thickness, resulting in defects such as "adhesive breaks" and "adhesive lumps". However, during the spray coating process, due to fluctuations in air pressure, there may be instances where the adhesive is not sprayed to the edge of the sandwich panel or exceeds the edge position, and the adhesive is sprayed onto the equipment, making it difficult to control the spraying position of the sandwich panel edge. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic glue application device and method for producing insulated sandwich panels. By providing shielding mechanisms on both sides of the conveying mechanism, it can prevent glue spraying from exceeding the edge of the sandwich panel while still applying glue to the edge of the sandwich panel, thereby solving the problems in the prior art.

[0005] To achieve the above-mentioned technical objectives, the specific technical solution of the present invention is as follows: The present invention proposes an automatic glue-applying equipment for the production of thermal insulation sandwich panels, comprising: a machine body, a conveying mechanism, a glue-applying mechanism, and a driving mechanism for driving the glue-applying mechanism to move laterally; the conveying mechanism is mounted on the machine body, and a fixed frame is fixedly connected above the machine body, and the driving mechanism is fixedly mounted on the fixed frame; a pair of shielding mechanisms are symmetrically arranged on both sides of the machine body to prevent the glue-applying mechanism from applying glue beyond the edge of the sandwich panel, and the shielding mechanisms can apply glue to the edge of the sandwich panel; the glue-applying mechanism includes a connecting frame, a lifting cylinder, a lifting seat, and a glue-applying valve fixedly mounted on the lifting seat, a glue tube fixedly connected below the glue-applying valve, and a glue spraying pipe fixedly connected to the lower end of the glue tube; the shielding mechanism includes a fixed arm, a vertical track frame fixedly connected to the fixed arm, a slider slidably connected inside the track frame, a glue-applying roller rotatably connected to the slider, and the lower surface of the glue-applying roller contacting the edge of the sandwich panel.

[0006] As a preferred embodiment of the present invention, the coating roller is coaxially fixedly connected to a rotating component, the lifting seat is fixedly connected to a bracket, the bracket is fixedly connected to a rack for driving the rotating component to rotate, and the slider is fixedly connected to a positioning wheel for positioning the rack, the positioning wheel being located directly above the rotating component.

[0007] As a preferred embodiment of the present invention, the rotating component includes an outer gear ring and a ratchet. The ratchet is rotatably connected to the inner circumference of the outer gear ring, and the glue-applying roller is coaxially and fixedly connected to the ratchet. The inner wall of the outer gear ring is connected with a plurality of pawls that cooperate with the ratchet, and an elastic element is connected between the pawls and the inner wall of the outer gear ring.

[0008] As a preferred embodiment of the present invention, the fixed arm is provided with a horizontal strip-shaped connecting hole, a connecting block is fixedly connected to the track frame, and a bolt assembly that mates with the connecting hole is fixedly connected to the connecting block; and a threaded rod is threadedly connected to the track frame, one end of which is rotatably connected to the slider.

[0009] As a preferred embodiment of the present invention, a fixed plate is fixedly connected below the lifting seat, and a swing frame is rotatably connected to the fixed plate. The lower end of the swing frame is fixedly connected to the glue spraying pipe, and the lower end of the glue spraying pipe is connected to the glue spraying pipe through a flexible hose.

[0010] As a preferred embodiment of the present invention, a top seat is fixedly connected to the upper end of the swing frame, a sliding groove is provided on the side of the top seat, and a top rod that cooperates with the top seat is fixedly connected to the slider.

[0011] As a preferred embodiment of the present invention, an air inlet pipe and an air outlet pipe are respectively connected to both sides of the glue applicator valve, and an glue inlet pipe is connected to the glue applicator valve.

[0012] As a preferred embodiment of the present invention, two rows of positioning plates are symmetrically arranged on the machine body for limiting the position of the sandwich panel on both sides.

[0013] A method for applying adhesive in the production of thermal insulation sandwich panels includes the following steps: Step 1: The conveying mechanism drives the sandwich panel forward. During the conveying process, the driving mechanism drives the gluing mechanism to reciprocate between the two shielding mechanisms. During the movement, the gluing mechanism sprays glue onto the surface of the sandwich panel. Step 2: When the glue application mechanism moves close to the masking mechanism, it pushes the top seat through the top rod, which drives the swing frame to rotate, and then drives the glue spraying tube to rotate towards the masking mechanism. During the rotation, glue is sprayed onto the area of ​​the sandwich panel near the glue application roller and the side of the glue application roller. Step 3: When the glue application mechanism moves away from the masking mechanism, the rack drives the rotating component to rotate, which in turn drives the glue application roller to rotate, applying the glue sprayed on the surface of the glue application roller to the edge of the sandwich panel.

[0014] The beneficial effects of this invention are as follows: 1. The present invention provides a pair of shielding mechanisms on both sides of the conveying mechanism. The shielding mechanisms can prevent the glue coating mechanism from spraying too much. Furthermore, through the design of the top rod and the top seat, the glue spraying pipe rotates towards the shielding mechanism when it approaches the shielding mechanism, thereby spraying the sandwich panel located below the glue coating roller.

[0015] 2. When the glue application mechanism of the present invention is close to the masking mechanism, it sprays glue onto the surface of the glue application roller by rotating the glue spraying pipe. When the glue application mechanism is away from the masking mechanism, it drives the glue application roller to rotate by the cooperation of the rack and the rotating part, and sprays glue onto the edge of the sandwich panel, thus avoiding the phenomenon of glue leakage due to incomplete spraying at the edge of the sandwich panel.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Example: This example discloses an automatic glue-applying equipment for the production of thermal insulation sandwich panels, such as... Figures 1-7 As shown, the system includes: a machine body 1, a conveying mechanism 6, an adhesive application mechanism 3, and a drive mechanism 2 that drives the adhesive application mechanism 3 to move laterally. The conveying mechanism 6 is mounted on the machine body 1 and adopts a conveying roller structure. A fixed frame 5 is fixedly connected to the top of the machine body 1. The fixed frame 5 has an inverted U-shaped structure. The drive mechanism 2 is fixedly mounted on the fixed frame 5. The drive mechanism 2 adopts a drive method that uses a motor to drive a lead screw to rotate, which drives the adhesive application mechanism 3 to move back and forth. The drive mechanism 2 can precisely control the left and right position of the adhesive application mechanism 3 by controlling the number of rotations of the lead screw through the system. The position of the adhesive application mechanism 3 remains fixed when it moves back and forth to the sides. A pair of shielding mechanisms 4 are symmetrically arranged on both sides of the machine body 1. The shielding mechanisms 4 are located above the edges of the sandwich panel on both sides. The shielding mechanisms 4 can be used to prevent the adhesive application mechanism 3 from coating beyond the edge of the sandwich panel, and the shielding mechanisms 4 can apply adhesive to the edge of the sandwich panel. Two rows of positioning plates 7 are symmetrically arranged on the machine body 1 to limit the sides of the sandwich panel, ensuring the accurate conveying position of the sandwich panel.

[0026] like Figures 3-4As shown, the glue application mechanism 3 includes a connecting frame 31, a lifting cylinder 32, a lifting seat 33, and a glue application valve 34 fixedly installed on the lifting seat 33. The connecting frame 31 is connected to the drive mechanism 2 via a slide. An air inlet pipe 38 and an air outlet pipe 39 are respectively connected to both sides of the glue application valve 34, and a glue inlet pipe 310 is connected to the glue application valve 34. One end of the glue inlet pipe 310 is connected to a glue pump, and glue is applied by the glue pump. A row of nozzles is provided on the lower surface of the glue spray pipe 36. A glue tube 35 is fixedly connected below the glue application valve 34. The glue tube 35 is made of rigid material, and the lower end of the glue tube 35 is connected to the spray pipe 36 via a flexible hose 37. The adhesive hose 36 is connected; a fixed plate 313 is fixedly connected below the lifting seat 33, and a swing frame 314 is rotatably connected to the fixed plate 313. The lower end of the swing frame 314 is fixedly connected to the adhesive spraying hose 36, and a top seat 315 is fixedly connected to the upper end of the swing frame 314. The side of the top seat 315 is provided with a sliding groove 316. When the swing frame 314 rotates, it will drive the adhesive spraying hose 36 to rotate, changing the spraying direction of the adhesive spraying hose 36. In its natural state, the adhesive spraying hose 36 sprays directly downwards; the lifting cylinder 32 can drive the adhesive spraying hose 36 to rise and fall, thereby adjusting the spraying height of the adhesive spraying hose 36.

[0027] like Figures 5-6 As shown, the shielding mechanism 4 includes a fixed arm 411, which has an inverted L-shaped structure. The fixed arm 411 is fixedly connected to the machine body 1. A vertical track frame 41 is fixedly connected to the fixed arm 411. A slider 42 is slidably connected inside the track frame 41, and a threaded rod 45 is threadedly connected to the track frame 41. One end of the threaded rod 45 is rotatably connected to the slider 42. A disc handle is fixedly connected to the upper end of the threaded rod 45. The height of the slider 42 can be adjusted by the threaded rod 45, thereby adjusting the height of the glue-applying roller 43. A top rod 410 that cooperates with the top seat 315 is fixedly connected to the slider 42, and the glue-applying roller 43 is rotatably connected to the slider 42. The surface of the glue-applying roller 43 is covered with a soft material. The lower surface of the glue-applying roller 43 contacts the edge of the sandwich panel, and the glue-applying roller 43 does not affect the normal conveying of the sandwich panel. When the glue-applying mechanism 3 moves closer to the shielding mechanism 4, the top rod 410 contacts the top seat 315, driving the swing frame 314 to rotate, which in turn drives the glue spraying pipe 36 to rotate towards the glue-applying roller 43. During the rotation, the sandwich panel located below the glue-applying roller 43 and the side of the glue-applying roller 43 are sprayed, and the spraying height will not exceed the height of the glue-applying roller 43. The glue-applying roller 43 plays the role of shielding the glue, preventing the glue from being sprayed beyond the edge of the sandwich panel, so as to avoid spraying onto the equipment.

[0028] Preferably, the fixed arm 411 is provided with a horizontal strip-shaped connecting hole 48, and a connecting block 46 is fixedly connected to the track frame 41. A bolt assembly 47 that mates with the connecting hole 48 is fixedly connected to the connecting block 46. The bolt assembly 47 includes a bolt and a nut, and the position of the glue roller 43 at the edge of the sandwich panel can be adjusted by the bolt assembly 47.

[0029] like Figure 7As shown, a rotating component 44 is coaxially fixedly connected to the glue-applying roller 43. A bracket 311 is fixedly connected to the lifting seat 33. A rack 312 for driving the rotating component 44 to rotate is fixedly connected to the bracket 311. A positioning wheel 49 is fixedly connected to the slider 42 for positioning the rack 312. The positioning wheel 49 is located directly above the rotating component 44. The rack 312 can move between the positioning wheel 49 and the rotating component 44. The positioning wheel 49 ensures that the rack 312 can be aligned with the rotating component 44. 4. Engagement; wherein, the rotating component 44 includes an outer gear ring 441 and a ratchet 442. The outer gear ring 441 can engage with the rack 312. The ratchet 442 is rotatably connected to the inner circumference of the outer gear ring 441, and the glue-applying roller 43 is coaxially and fixedly connected to the ratchet 442. Multiple pawls 443 that cooperate with the ratchet 442 are connected to the inner wall of the outer gear ring 441. An elastic element 444 is connected between the pawls 443 and the inner wall of the outer gear ring 441; the elastic element 444 makes the pawls 443 contact the ratchet 442. In specific implementation: When the glue application mechanism 3 moves towards the masking mechanism 4, the top rod 410 contacts the top seat 315, causing the swing frame 314 to rotate, which in turn causes the glue spraying pipe 36 to rotate towards the glue application roller 43, spraying the sandwich panel located below the glue application roller 43 and the side of the glue application roller 43; at the same time, the rack 312 drives the outer gear ring 441 to rotate counterclockwise. At this time, the outer gear ring 441 will not drive the ratchet 442 to rotate, and the glue application roller 43 remains stationary; when the glue application mechanism 3 moves towards the masking mechanism 4, the top rod 410 contacts the top seat 315, causing the swing frame 314 to rotate, which in turn drives the spraying pipe 36 to rotate towards the glue application roller 43, thus spraying the sandwich panel located below the glue application roller 43 and the side of the glue application roller 43. During the movement away from the shielding mechanism 4, the glue spray tube 36 returns to the downward position, and at the same time, the rack 312 drives the outer gear ring 441 to rotate clockwise. At this time, the outer gear ring 441 drives the ratchet 442 to rotate, and the ratchet 442 drives the glue application roller 43 to rotate. The glue application roller 43 applies the glue sprayed on its surface to the edge of the sandwich panel. Compared with the existing spray-type glue application equipment, this embodiment has the advantage of avoiding the glue spraying position from exceeding the edge of the sandwich panel, while ensuring that the edge of the sandwich panel will not leak glue.

[0030] This embodiment also discloses an adhesive coating method for the production of thermal insulation sandwich panels, based on the above-mentioned adhesive coating equipment, including the following steps: Step 1: The conveying mechanism 6 drives the sandwich panel forward. During the conveying process, the driving mechanism 2 drives the gluing mechanism 3 to reciprocate between the two shielding mechanisms 4. During the movement, the gluing mechanism 3 sprays glue onto the surface of the sandwich panel. Step 2: When the glue application mechanism 3 moves close to the masking mechanism 4, the top rod 410 pushes the top seat 315, which drives the swing frame 314 to rotate, and then drives the glue spraying tube 36 to rotate towards the masking mechanism 4. During the rotation, glue is sprayed onto the area of ​​the sandwich panel close to the glue application roller 43 and the side of the glue application roller 43. Step 3: When the glue application mechanism 3 moves away from the masking mechanism 4, the rack 312 drives the rotating part 44 to rotate, and the rotating part 44 drives the glue application roller 43 to rotate, so that the glue sprayed on the surface of the glue application roller 43 is applied to the edge of the sandwich panel.
