Description

Technical Field

[0001] This invention relates to the field of honeycomb panel production equipment technology, specifically to a spray adhesive device for honeycomb panel production. Background Technology

[0002] A honeycomb panel is a board made by firmly bonding two thinner panels to both sides of a thicker honeycomb core material. It is also known as a honeycomb sandwich structure. In the production process of honeycomb panels, glue is first applied to one side of the panel, and then the two glued panels are bonded to both sides of the honeycomb core material. A glue spraying device is required in this process.

[0003] In existing honeycomb panel production processes, the glue spraying equipment mainly applies glue to one side of the panel. During the glue application process, the entire surface of the panel is coated with glue. However, because the two sides of the honeycomb core material are mainly wavy during the bonding process, the surface of the panel cannot make contact with the side of the honeycomb core material during the bonding process, which results in a waste of glue on the side wall of the panel. The glue application process requires applying glue to two panels and then bonding a honeycomb core material to complete the production of a honeycomb panel, which also greatly affects the production efficiency. Summary of the Invention

[0040] Secondly, the present invention is described in detail with reference to the schematic diagrams.

[0041] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0042] This invention provides a glue spraying device for honeycomb panel production, which replaces the traditional glue spraying method in honeycomb panel production. It avoids the waste of glue during the glue spraying process and the problem of affecting the production efficiency of honeycomb panels by spraying multiple panels.

[0043] Figures 1-8The diagram shown is a structural schematic of a spray adhesive device for honeycomb panel production according to the present invention. Please refer to [link / reference]. Figures 1-8 This paper provides a detailed introduction to the adhesive spraying device used in the production of honeycomb panels.

[0044] Example 1

[0045] refer to Figures 1-8 The present invention discloses a glue spraying device for honeycomb panel production, the main body of which includes a support mechanism 100, a glue coating mechanism 200 and a glue scraping mechanism 300.

[0046] refer to Figures 1-2 The support mechanism 100 is used to support the entire device and facilitate the transmission of the honeycomb core material to be coated with adhesive. The support mechanism 100 includes a conveying component 110 for conveying the honeycomb core material and a support component 120 installed on the side wall of the conveying component 110. The conveying component 110 is used to drive the honeycomb core material to move, thereby facilitating the coating of adhesive on its two side surfaces. The support component 120 is used to fix and support the conveying component 110 and at the same time support the entire device.

[0047] refer to Figures 1-2 The gluing mechanism 200 is used to apply glue to both sides of the honeycomb core material during the transmission of the honeycomb core material by the conveying assembly 110. The gluing mechanism 200 includes a mounting frame 210 mounted on the support assembly 120, a gluing assembly 220 mounted on the mounting frame 210 that automatically applies glue to the honeycomb core material after contact with it on the conveying assembly 110, and a glue tank 230 mounted on the mounting frame 210 for intermittently supplying glue to the gluing assembly 220 when it applies glue. The mounting frame 210 is used for... The adhesive application assembly 220 and the glue tank 230 are easy to install. The adhesive application assembly 220 is used to automatically apply glue to both sides of the honeycomb core material when it comes into contact with the honeycomb core material. After one glue application operation, the panels can be directly bonded to both sides, which greatly improves the production efficiency of honeycomb panels. The glue tank 230 is used to store the glue and automatically deliver the glue to it during the glue application process of the adhesive application assembly 220, thereby avoiding the problem of glue loss during the glue application process of the adhesive application assembly 220, which would require re-applying glue and affect the glue application efficiency.

[0048] refer to Figures 1-3The adhesive scraping mechanism 300 is used to scrape off the glue dripping from the conveying component 110 during operation, thereby preventing glue from overflowing and causing pollution and making it inconvenient for workers to clean up. The adhesive scraping mechanism 300 is installed on the mounting bracket 210. When the glue application component 220 is working, it automatically drives the adhesive scraping mechanism 300 to scrape off the glue on the conveying component 110 after applying glue to the honeycomb core material. Since the glue applied to the side wall of the honeycomb core material is prone to forming droplets and dripping onto the conveying component 110, the adhesive scraping mechanism 300 prevents the glue dripping from the conveying component 110 from dripping onto the ground and causing pollution and increasing the workload of cleaning.

[0049] In this embodiment, the specific usage process is as follows: The honeycomb core material to be coated is erected on the conveying assembly 110 and moved. When the honeycomb core material comes into contact with the coating assembly 220, the coating assembly 220 automatically coats both sides of the honeycomb core material with glue. At the same time, the glue tank 230 automatically feeds glue into the coating assembly 220. During the coating process, the coating assembly 220 automatically drives the scraping mechanism 300 to start working to scrape off the glue dripping on the conveying assembly 110, thereby avoiding environmental pollution caused by glue and making it inconvenient to clean.

[0050] Example 2

[0051] Based on Example 1, and referring to Figure 2 The conveying assembly 110 includes a conveyor belt and a motor 110b connected to the drive roller of the conveyor belt 110a. The motor 110b is used to drive the drive roller of the conveyor belt 110a to rotate during operation, thereby driving the conveyor belt 110a to rotate. During the rotation of the conveyor belt 110a, the honeycomb core material is moved and the honeycomb core material to be coated is placed on the top surface of the conveyor belt 110a. When the motor 110b starts to rotate, it drives the conveyor belt 110a to start moving, thereby driving the honeycomb core material placed on the top surface of the conveyor belt 110a to move.

[0052] In this embodiment, reference Figure 2 The support assembly 120 includes two support bases 120a located on both sides of the conveyor belt 110a, which are used to support both sides of the conveyor belt 110a respectively. The support bases 120a are in contact with the ground, indirectly supporting the entire device and maintaining the overall stability.

[0053] In this embodiment, reference Figures 2-3The mounting frame 210 includes a base plate 210a located on the side wall of the conveyor belt 110a, two vertical plates 210b located on top of the base plate 210a, and a top plate 210c located on top of the two vertical plates 210b. The base plate 210a is used to facilitate the installation of the glue application assembly 220 and the glue scraping mechanism 300. The vertical plates 210b are used to support the top plate 210c. The top plate 210c is used to facilitate the installation of the glue tank 230 and to support the glue tank 230.

[0054] In this embodiment, reference Figures 3-4 The surface of the base plate 210a is provided with a first limiting groove 210a-2, which is internally slidably connected to a first moving block 210a-21. The first moving block 210a-21 is used to connect with the rotating drum 220a. When the first moving block 210a-21 moves along the first limiting groove 210a-2, it is convenient to adjust the relative distance between the glue application components 220 on both sides of the conveying component 110, thereby facilitating the application of glue to honeycomb core materials of different thicknesses.

[0055] refer to Figures 3-6 The surface of the top plate 210c has a groove 210c-1 with a storage groove 210c-11 at the bottom of the inner wall. The groove 210c-1 is used to receive glue from the inside of the box 230a. The storage groove 210c-11 is used to facilitate the installation of the elastic shrink plate 210c-111. The two ends of the storage groove 210c-11 are provided with elastic shrink plates 210c-111. When the glue application assembly 220 moves, the elastic shrink plates 210c-111 will shrink and seal the gap between the storage groove 210c-11 and the feed port 220a-2 to prevent glue leakage.

[0056] refer to Figures 3-6 The adhesive application assembly 220 includes a rotating cylinder 220a whose bottom is connected to the top of the first moving block 210a-21 and has a first through hole on its side wall, and a sponge sleeve 220b located outside the rotating cylinder 220a. The interior of the rotating cylinder 220a is used to store adhesive. The adhesive is absorbed by the sponge sleeve 220b through the first through hole. When the sponge sleeve 220b comes into contact with the honeycomb core material, it rotates, and then the sponge sleeve 220b applies the absorbed adhesive to both sides of the honeycomb core material. The top of the rotating cylinder 220a is provided with an inlet 220a-2 that extends into the groove 210c-1 and is connected to the side walls of two elastic shrink plates 210c-111 on both sides, for inputting the adhesive in the groove 210c-1 into the interior of the rotating cylinder 220a, thereby providing adhesive for the adhesive application.

[0057] In this embodiment, reference Figures 4-5The rotating drum 220a has a dispensing cylinder 220a-3 inside, which has a dispensing port 220a-31 at the top and a second hole 220a-32 on the bottom side wall. The dispensing cylinder 220a-3 is used to allow the glue entering the rotating drum 220a through the inlet 220a-2 to be absorbed by the sponge sleeve 220b more quickly through the first hole 220a-1. The dispensing port 220a-31 is used to introduce part of the glue into the dispensing cylinder 220a-3, and then through the second hole 220a-32 it is absorbed by the sponge sleeve 220b at the bottom. The 0b absorbs the adhesive, thus avoiding insufficient adhesive at the bottom of the sponge sleeve 220b, which would lead to uneven adhesive application. The dispensing port 220a-31 corresponds to the inlet port 220a-2 and has a smaller diameter than the inlet port 220a-2. This is to prevent excessive adhesive diversion. When the adhesive enters the inside of the rotating drum 220a through the inlet port 220a-2, some of the adhesive enters the dispensing cylinder 220a-3 through the dispensing port 220a-31, thus facilitating more even absorption of the adhesive by the sponge sleeve 220b.

[0058] In this embodiment, reference Figure 3 and Figure 6 The glue tank 230 includes a box body 230a located on top of the top plate 210c and having a through groove 230a-1 at the bottom, and an elastic seal 230b movably installed inside the through groove 230a-1 for opening and closing the through groove 230a-1. The box body 230a is used to store glue, the through groove 230a-1 is used to guide the glue inside the box body 230a into the groove 210c-1, and the elastic seal 230b is used to facilitate opening and closing the through groove 230a-1, thereby controlling the amount of glue flowing out.

[0059] In this embodiment, reference Figures 4-6 Multiple connecting rods 220a-21 are evenly arranged along the circumferential direction on the outer wall of the feed inlet 220a-2. When the rotating drum 220a rotates, the multiple connecting rods 220a-21 rotate, and then the connecting rods 220a-21 continuously strike the baffle 230b-12.

[0060] refer to Figure 6 The inner wall of the through groove 230a-1 is provided with a connecting groove 230a-11 to facilitate the connection of the connecting column 230b-11, thereby realizing the movable connection between the sealing plate 230b-1 and the through groove 230a-1;

[0061] refer to Figures 4-6The elastic seal 230b includes a sealing plate 230b-1 with connecting posts 230b-11 on both sides for sealing the through groove 230a-1. A torsion spring 230b-111, one end of which is connected to the side wall of the connecting post 230b-11 and the other end of which is connected to the inner wall of the connecting hole, is sleeved on the connecting post 230b-11. Under the torsion of the torsion spring 230b-111, the sealing plate 230b-1 drives the sealing plate 230b-1 to seal the through groove 230a-1, thereby preventing glue from flowing down and achieving a seal. The bottom of plate 230b-1 is provided with a baffle 230b-12 corresponding to the connecting rod 220a-21, which is used to cooperate with the connecting rod 220a-21. When the rotating drum 220a rotates, it drives the connecting rod 220a-21 to rotate. When the connecting rod 220a-21 rotates, it hits the baffle 230b-12 in sequence, thereby causing the sealing plate 230b-1 to rotate downward intermittently, thereby realizing the intermittent input of glue in the box 230a into the groove 210c-1;

[0062] In this embodiment, reference Figure 3 The surface of the base plate 210a is provided with a second limiting groove 210a-3, which is internally slidably connected to a second moving block 210a-31. The second connecting block is used to connect with the scraper roller 310 and slide in the second limiting groove 210a-3. It is used to cooperate with the glue application component 220 to achieve synchronous adjustment when facing honeycomb core materials of different thicknesses.

[0063] refer to Figure 1-3 The glue scraping mechanism 300 includes a glue scraping roller 310 located on the top of the second moving block 210a-31 and having multiple scrapers on its side wall, and a transmission component 320 with one end rotatably connected to the glue scraping roller 310 and the other end drivingly connected to the rotating drum 220a. The glue scraping roller 310 is used to scrape off the glue dripping from the surface of the conveyor belt when it rotates. The transmission component 320 is used to drive the glue scraping roller 310 and the rotating drum 220a respectively, thereby realizing that when the rotating drum 220a rotates to apply glue to the honeycomb core material, it automatically drives the glue scraping roller 310 to rotate to scrape the glue from the surface of the conveyor belt.

[0064] refer to Figures 3-7The transmission assembly 320 includes a first gear 320a connected at its top to the bottom of a rotating drum 220a via a rotating shaft, a second gear 320b connected at its top to the bottom of a scraper roller 310 via a rotating shaft and meshing with the first gear 320a, and a connecting frame 320v whose top is connected to the bottom of both the first gear 320a and the second gear 320b. The first gear 320a drives the rotating drum 220a to rotate, and in turn, the rotation of the first gear 320a drives the rotation of the second gear 320b. The second gear 320b is used for... When the first gear 320a rotates, it drives the scraper roller 310 to rotate. The connecting frame 320v is used to connect the first gear 320a and the second gear 320b. When the honeycomb core material moving device contacts the sponge sleeve 220b, the rotating drum 220a starts to rotate to apply glue to the honeycomb core material. At this time, the first gear 320a rotates, driving the second gear 320b to reverse. Then, the second gear 320b reverses, driving the scraper roller 310 to reverse, thereby scraping off the glue on the surface of the conveyor belt.

[0065] In this embodiment, reference Figure 3 A screw rod is threaded onto the side wall of the base plate 210a, extending into the first limiting slide groove 210a-2 and connected to the side wall of the first moving block 210a-21. This screw rod extends and retracts within the first limiting slide groove 210a-2 during rotation, thereby moving the first moving block 210a-21 within the first limiting slide groove 210a-2. A knob is provided at the end of the screw rod away from the first moving block 210a-21, used to rotate the screw rod, thereby causing it to extend and retract along the side wall of the base plate, thus moving the first moving block 210a-21. The first moving block 210a-21 slides within the first limiting groove 210a-2. When it is necessary to adjust the distance between the glue application component 220 and the honeycomb core material, the knob is turned, which drives the screw to rotate and move the first moving block 210a-21, which in turn moves the glue application component 220. This improves the applicability of the device when applying glue to honeycomb core materials of different thicknesses and sizes, thereby reducing the production cost of enterprises and eliminating the need to customize different devices according to production needs.

[0066] In this embodiment, the specific usage process is as follows: The honeycomb core material to be coated with adhesive is placed vertically on the top surface of the conveyor belt 110a. Then, the motor 110b starts working and drives the conveyor belt 110a to move. As the conveyor belt 110a moves, it also drives the honeycomb core material to move until both sides of the honeycomb core material come into contact with the sponge sleeve 220b. Under the action of friction, the honeycomb core material drives the sponge sleeve 220b and the rotating drum 220a to rotate, thereby absorbing the adhesive on the sponge sleeve 220b and applying it to both sides of the honeycomb core material. At the same time, when the rotating drum 220a rotates, it drives the connecting rods 220a-21 to start rotating. When multiple connecting rods 220a-21 rotate, they strike the baffle 320b-12, thereby intermittently driving the sealing plate 220b-1 to rotate downwards. The adhesive inside the housing 230a is intermittently discharged through the channel 230a-1 and falls into the groove 210c-1. The adhesive inside the groove 210c-1 enters the rotating drum 220a through the feed port 220a-2, and is then absorbed by the sponge sleeve 220b through the first hole 220a-1 and the second hole 220a-32, making it convenient for the next honeycomb core material to be coated, thus ensuring the continuity of the coating. During the rotation of the rotating drum 220a, the first gear 320a is driven to rotate. When the first gear 320a rotates, it drives the second gear 320b to rotate. When the second gear 320b rotates, it drives the scraper roller 310 to rotate. In turn, multiple scrapers scrape off the adhesive on the surface of the conveyor belt 110a, avoiding the contamination of the conveyor belt 110a and the waste of adhesive.

[0067] Example 3

[0068] Based on Example 2, to avoid waste caused by the adhesive scraping mechanism 300 scraping off the adhesive, refer to Figures 3-8 The surface of the base plate 210a is provided with a glue guide groove 210a-1 located on one side of the glue scraper roller 310, which is used to receive the glue scraped off when the glue scraper roller 310 rotates.

[0069] The bottom of the second gear 320b is provided with a first pulley 320b-1, which drives the second pulley 430a to rotate when it rotates;

[0070] It also includes a glue guiding mechanism 400, which automatically guides the scraped glue back into the housing 230a when the glue scraper roller 310 rotates, thereby realizing the reuse of glue and avoiding glue waste. The glue guiding mechanism 400 includes a collection box 410 with a glue inlet groove 410a on the side wall, a glue guiding tube 420 extending into the collection box 410 and having a third hole 420a on the bottom side wall, and an auger 430 located in the glue guiding tube 420 and having a second pulley 430a at the bottom. The auger 430 is used to transport the glue inside the collection box 410 upward into the glue delivery tube 420b when it rotates. The collection box 410 is used to collect the glue scraped when the glue scraper roller 310 rotates. The glue inlet groove 410a is used to guide the glue in the glue guiding groove 210a-1 into the collection box 410. The glue guiding tube 420 is used to... The glue inside the collection box 410 is introduced into the box 230a. The third hole 420a is used to facilitate the glue inside the collection box 410 to enter the glue guide tube 420 through the third hole 420a. The glue inlet 410a corresponds to the glue guide 210a-1 and is used to facilitate the glue in the glue guide 210a-1 to enter the collection box 410 through the glue inlet 410a. The second pulley 430a is connected to the first pulley 320b-1 by a belt. When the glue scraper roller 310 rotates, it drives the first pulley 320b-1 to rotate, which in turn drives the second pulley 430a to rotate. The top of the glue guide tube 420 is provided with a glue delivery tube 420b, which is connected to the box 230a at the other end. It is used to introduce the glue input by the auger 430 into the box 230a and then collect it again by the box 230a.

[0071] In this embodiment, the specific usage process is as follows: When the scraper roller 310 rotates, it scrapes the water on the surface of the conveyor belt into the glue guide groove 210a-1. The glue enters the collection box 410 through the glue guide groove 210a-1 and the glue inlet groove 410a and is collected. At this time, the glue enters the bottom of the glue guide tube 420 through the third hole 420a. At this time, the rotation of the first gear 320a drives the first pulley 320b-1 to rotate. When the first pulley 320b-1 rotates, it drives the second pulley 430a to rotate. When the second pulley 430a rotates, it drives the auger 430 to rotate in the glue guide tube 420, thereby conveying the glue that has entered the bottom of the glue guide tube 420 upwards. Then, it enters the box 230a through the glue delivery tube 420b and is collected again for subsequent glue application and reuse.
