Description

Technical Field

[0001] This invention relates to the field of floor adhesive application equipment technology, specifically to a multi-layer floor adhesive application device and method. Background Technology

[0002] Multi-layer flooring, also known as composite flooring, is made by gluing together two or more pieces of solid wood flooring. Its production process includes five steps: first, cutting the whole wood board into small pieces; second, applying glue to the cut pieces; third, pre-bonding the glued pieces with the un-glued pieces (as disclosed in application number 201721298268.3, a handheld wood flooring gluing device); fourth, transferring the pre-glued multi-layer flooring to a hot-pressing device; and fifth, hot-pressing the pre-glued multi-layer flooring into shape. However, existing technology is cumbersome. After applying glue in the second step, the glued pieces must be collected and then placed on a pre-bonding device for pre-bonding with the un-glued pieces. Then, the pre-bonded multi-layer flooring is transferred piece by piece to the hot-pressing device in the fifth step. This increases production steps, reduces production efficiency, and is labor-intensive, thus reducing the company's economic benefits. Summary of the Invention

[0003] To address the technical problems mentioned in the background section, the present invention provides a multi-layer floor adhesive application device, employing the following technical solution: The system includes a strip conveyor, with several fixed plates on both sides and a guard plate fixed to each plate. The bottom of the guard plate is suspended above the strip of the strip conveyor. An adhesive applicator is installed inside the guard plate, with its bottom suspended above the strip of the strip conveyor. Several placement mechanisms are installed on the strip of the strip conveyor, with a lower floor on each placement mechanism. An adhesive bonding mechanism is also installed inside the guard plate, with an upper floor inside each adhesive bonding mechanism. The bottom of the adhesive bonding mechanism is suspended above the strip of the strip conveyor, and the adhesive bonding mechanism is offset from the right end of the strip conveyor by a certain distance.

[0004] Furthermore, the glue application mechanism includes a glue application chamber, a glue outlet at the bottom of the glue application chamber, a glue transfer cylinder above the glue outlet, shaft ends on both sides of the glue transfer cylinder penetrating the glue application chamber, shaft plates on both sides of the bottom of the glue application chamber, a glue application cylinder below the glue outlet, shaft ends on both sides of the glue application cylinder penetrating the shaft plates, and glue application chamber connecting plates on both sides of the glue application chamber, which are connected to the guard plate.

[0005] Furthermore, the placement mechanism includes a tray with a groove on it. The right end of the groove is open. A lower floor is placed inside the groove, and the upper part of the lower floor is higher than the groove. An L-shaped lever is provided on the left side of the tray, and a fixing rod is provided at the bottom of the tray. The fixing rod is fixed to the steel belt of the steel belt machine.

[0006] Furthermore, the bonding mechanism includes a stacking component and a pushing component. The pushing component is located on the left side of the stacking component. The stacking component includes a stacking compartment, in which several upper floorboards are stacked. A pushing hole is provided on the left side of the stacking compartment, and an outlet hole is provided on the right side of the stacking compartment. Stacking compartment connecting plates are provided on both sides of the stacking compartment, and the stacking compartment connecting plates are connected to the guard plate.

[0007] Furthermore, the pushing component includes a set of slats disposed on the left side of the stacking compartment. The slats are located on both sides of the pushing hole. A frame is provided on the slats, and a slide groove is provided on the frame. A slider is disposed in the slide groove. A pushing block is disposed inside the frame and connected to the slider. A pushing rod is disposed on the pushing block, and a first spring is disposed on the pushing rod. One end of the first spring is connected to the pushing block and the other end is connected to the frame. The pushing rod passes through the frame and has a pushing plate at its end. A first wedge block is disposed on the pushing block, and a second wedge block is disposed at the bottom of the frame. The first wedge block and the second wedge block are located on the same horizontal plane. The front end of the first wedge block is longer than the front end of the second wedge block. An elastic element is disposed inside the pushing block.

[0008] Furthermore, the elastic element includes a slide chamber disposed inside the push block, a first wedge block disposed inside the slide chamber, a limit rod disposed inside the slide chamber, the limit rod passing through the push block, the limit rod being connected to the first wedge block, and a second spring disposed on the limit rod, one end of the second spring being connected to the first wedge block and the other end being connected to the slide chamber.

[0009] The adhesive application method includes the following steps: Step 1: Place the lower floorboards into each placement mechanism; Step 2: The placement mechanism moves to the right under the drive of the steel belt of the steel belt machine. When the placement mechanism passes under the glue application mechanism, the lower floor is glued by the glue application mechanism during the movement. Step 3: When the placement mechanism moves the glued lower floorboard to the bottom of the stacking bin, it pushes one end of the bonding mechanism. The bonding mechanism then pushes the upper floorboard inside, causing both the upper and lower floorboards to move to the right simultaneously. When the upper floorboard inside the bonding mechanism is pushed out and falls, it lands on the lower floorboard and adheres to the glue on it. Meanwhile, the placement mechanism disengages from one end of the bonding mechanism, and the other end of the bonding mechanism springs back into place. The same steps are repeated when the next placement mechanism moves to the bottom of the stacking bin. The glued upper and lower floorboards continue to move a certain distance to the right on the steel belt of the belt conveyor until they reach the right end of the belt and flip and fall as the belt rotates. During this process, the upper and lower floorboards are given a certain amount of time to adhere and fix themselves.

[0010] The present invention has the following advantages: 1. Place the lower floorboards into each placement mechanism. Driven by the steel belt conveyor, the placement mechanism moves to the right. As it passes under the gluing mechanism, the lower floorboards are coated with adhesive during this movement. When the placement mechanism, carrying the coated lower floorboards, moves to the underside of the stacking bin, it pushes one end of the bonding mechanism. The bonding mechanism then pushes the upper floorboards inside, causing both the upper and lower floorboards to move to the right simultaneously. When the upper floorboards inside the bonding mechanism are pushed out and fall, they land directly on the lower floorboards, adhering to the adhesive on them. Meanwhile, the placement mechanism detaches from the bonding mechanism. One end of the bonding mechanism and the other end of the adhesive mechanism spring back to their original positions. When the next placement mechanism moves to the bottom of the stacking bin, the above steps are repeated. After bonding, the upper and lower floorboards continue to move to the right a certain distance on the steel belt of the steel belt machine and reach the right end of the steel belt machine. As the steel belt rotates, they flip and fall off. This invention achieves the application of glue to the lower floorboards and the continuous pushing of the lower floorboards through one process using the conveying of the steel belt of the steel belt machine. At the same time, it also achieves the continuous and batch automatic bonding of the upper and lower floorboards, which greatly improves the glue application and bonding efficiency of the floorboards and the production efficiency.

[0011] 2. This invention utilizes the synchronous conveying of the lower floorboard by the steel belt of the steel belt conveyor and the synchronous ejection of the upper floorboard stacked in the bonding mechanism by the placement mechanism, so that the bonding position of the upper and lower floorboards is more precise and synchronized.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please refer to Figure 1 This invention provides a multi-layer flooring adhesive applicator, including a steel belt machine 1. Several fixing plates 2 are provided on both sides of the steel belt machine 1, and a protective plate 3 is fixed to each fixing plate 2. The bottom of the protective plate 3 is suspended above the steel belt of the steel belt machine 1. The fixing plates 2 secure the protective plate 3 to the steel belt of the steel belt machine 1, preventing it from contacting the protective plate 3 when the steel belt machine 1 rotates. An adhesive applicator is provided inside the protective plate 3 for applying adhesive to the lower flooring 4. The bottom of the adhesive applicator is suspended above the steel belt of the steel belt machine 1. Several placement mechanisms are provided on the steel belt of the steel belt machine 1, and each placement mechanism holds one lower flooring 4. An adhesive bonding mechanism is also provided inside the protective plate 3, and an upper flooring 16 is placed inside the adhesive bonding mechanism. The bottom of the adhesive bonding mechanism is suspended above the steel belt of the steel belt machine 1 and is offset from the right end of the steel belt machine 1 by a certain distance, so that the upper flooring 16 is bonded to the lower flooring 4. Afterwards, it can move on the steel belt of the steel belt machine 1 for a period of time. During this time, the bonding time between the upper floor 16 and the lower floor 4 is increased, making the upper floor 16 and the lower floor 4 bond more firmly. When the placement mechanism moves the lower floor 4 with the glue applied to the bottom side of the stacking bin 15, the placement mechanism pushes one end of the bonding mechanism. The bonding mechanism pushes the upper floor 16 inside it, so that the upper floor 16 and the lower floor 4 move to the right synchronously. When the upper floor 16 in the bonding mechanism is pushed out and falls, it falls on the lower floor 4 and bonds with the glue on the lower floor 4. The placement mechanism just disengages from one end of the bonding mechanism. One end of the bonding mechanism springs back to its original position. When the next placement mechanism moves to the bottom side of the stacking bin 15, the above steps are repeated. The bonded upper floor 16 and lower floor 4 continue to move to the right a certain distance on the steel belt of the steel belt machine 1 and reach the right end of the steel belt of the steel belt machine 1. As the steel belt rotates, they flip and fall off.

[0016] Please refer to Figure 2-3 The glue application mechanism includes a glue application tank 5, with a glue outlet 6 at the bottom of the glue application tank 5. A glue transfer cylinder 7 is located above the glue outlet 6, and the outer surface of the glue transfer cylinder 7 has a gear-shaped structure. The shaft ends on both sides of the glue transfer cylinder 7 pass through the glue application tank 5, allowing the glue transfer cylinder 7 to rotate on the glue application tank 5. Shaft plates 8 are located on both sides of the bottom of the glue application tank 5, and a glue application cylinder 9 is located below the glue outlet 6. The shaft ends on both sides of the glue application cylinder 9 pass through the shaft plates 8, allowing the glue application cylinder 9 to rotate on the shaft plates 8. The upper part of the glue application cylinder 9 contacts the bottom of the glue transfer cylinder 7. The glue application cylinder 9 is made of sponge material. When the lower floor 4 moves to the right, it contacts the bottom of the glue application cylinder 9. The glue-applying cylinder 9 rotates, which drives the glue transfer cylinder 7 to rotate. The glue in the glue-applying tank 5 is pushed out through the toothed grooves on the glue transfer cylinder 9 and rotated to be transferred to the glue-applying cylinder 9, so that the glue on the glue-applying cylinder 9 is coated on the lower floor 4. The toothed grooves on the glue transfer cylinder 7 ensure that the glue in the glue-applying tank 5 can be transferred out, and the glue transfer cylinder 7 can also form a seal with the glue outlet 6, so that the glue in the glue-applying tank 5 will only leak out when the glue transfer cylinder 7 is rotating. Glue-applying tank connecting plates 10 are provided on both sides of the glue-applying tank 5. The glue-applying tank connecting plates 10 are connected to the guard plate 3, and the glue-applying tank 5 is suspended and fixed through the glue-applying tank connecting plates 10.

[0017] Please refer to 4-6. The placement mechanism includes a pallet 11 with a groove 12 on it. The right end of the groove 12 is open. A lower floor 4 is placed inside the groove 12, with the upper part of the lower floor 4 higher than the groove 12. The lower floor 4 is placed inside the groove 12 and is limited. The right end of the groove 12 is open, so that after the upper floor 16 and the lower floor 4 are bonded together, the pallet 11 reaches the right end of the steel belt. As the steel belt rotates, when the pallet 11 flips, the bonded upper floor 16 and lower floor 4 can be tilted out and detached from the pallet 11. An L-shaped lever 13 is provided on the left side of the pallet 11. The upper end of the L-shaped lever 13 is lower than the bottom of the stacking bin 15, so that the L-shaped lever 13 can pass through the bottom of the stacking bin 15. A fixing rod 14 is provided at the bottom of the pallet 11 and is fixed to the steel belt of the steel belt machine 1.

[0018] The bonding mechanism includes a stacking component and a pushing component. The pushing component is located on the left side of the stacking component. The stacking component includes a stacking chamber 15, in which several upper floorboards 16 are stacked. The pushing component can push out the upper floorboards 16 in the stacking chamber 15 and then quickly return to its original position. A pushing hole 17 is provided on the left side of the stacking chamber 15, and an outlet hole 18 is provided on the right side of the stacking chamber 15. Stacking chamber connecting plates 19 are provided on both sides of the stacking chamber 15. The stacking chamber connecting plates 19 are connected to the guard plate 3, and the stacking chamber 15 is suspended and fixed through the stacking chamber connecting plates 19.

[0019] Please refer to Figure 7-8The pushing component includes a set of slats 20 disposed on the left side of the stacking compartment 15. The slats 20 are located on both sides of the push hole 17. A frame 21 is disposed on the slats 20. A groove 22 is disposed on the frame 21. A slider 23 is disposed in the groove 22 and slides within the groove 22. A push block 24 is disposed inside the frame 21. The slider 23 drives the push block 24 to move within the frame 21. The push block 24 is connected to the slider 23. A push rod 25 is disposed on the push block 24. The push rod 25 moves with the push block 24. A first spring 26 is disposed on the push rod 25. One end of the first spring 26 is connected to the push block 24 and the other end is connected to the frame 21. The push rod 25 passes through the frame 21 and has a push plate 27 at its end. When the push block 24 drives the push rod 25 to move, the push rod 25 drives the push plate 27 to move inside the slats 20, compressing the first spring 26. The push block 24 is disposed on the push rod 25. There is a first wedge block 28, and a second wedge block 29 is provided at the bottom of the frame 21. The first wedge block 28 and the second wedge block 29 are located on the same horizontal plane. The front end of the first wedge block 28 is longer than the front end of the second wedge block 29. The L-shaped lever 13 is located at the front end of the second wedge block 29. When the L-shaped lever 13 moves to the right, it moves the first wedge block 28 to the right. The first wedge block 28 drives the push block 24 to move to the right. When the first wedge block 28 and the second wedge block 29 slide into contact, the first wedge block 28 retracts into the push block 24, and the L-shaped lever 13 disengages from the first wedge block 28. Without the restriction of the L-shaped lever 13, the first spring 26 quickly rebounds and drives the push block 24 to move to the left. The L-shaped lever 13 continues to move to the right and does not contact the second wedge block 29. An elastic element is provided inside the push block 24. Under the action of the elastic element, the first wedge block 29 also rebounds and returns to its original position.

[0020] The elastic element includes a slide 30 disposed inside the push block 24. A first wedge block 28 is disposed inside the slide 30. A limit rod 31 is disposed inside the slide 30. The limit rod 31 passes through the push block 24 and is connected to the first wedge block 28. A second spring 32 is disposed on the limit rod 31. One end of the second spring 32 is connected to the first wedge block 28 and the other end is connected to the slide 30. When the first wedge block 28 retracts into the slide 30, the second spring 32 is compressed. The first wedge block 28 simultaneously drives the limit rod 31 to move. The limit rod 31 passes through the push block 24 and restricts the movement trajectory.

[0021] The working principle of this invention is as follows: The lower floor 4 is placed in the groove 12. The fixing rod 14, the L-shaped lever 13, and the support plate 11 move to the right as the steel belt of the steel belt conveyor 1 moves. When the lower floor 4 moves to the bottom of the glue coating cylinder 9 and comes into contact with it, the glue coating cylinder 9 rotates under the action of friction. The glue coating cylinder 9 drives the glue transfer cylinder 7 to rotate. The glue transfer cylinder 7 carries the glue in the glue coating bin 5 and attaches it to the glue coating cylinder 9 through the glue outlet 6. The glue on the glue coating cylinder 9 is coated onto the lower floor 4. After the glue is applied, when the lower floor 4 moves directly below the stacking bin 15, the L-shaped lever is just in time to reach the bottom. 13 contacts the first wedge block 28 and drives the first wedge block 28 to move to the right. The first wedge block 28 drives the slider 23 to slide in the slide groove 22. The first wedge block 28 drives the push block 24. The push block 24 drives the push rod 25 and the push plate 27 to move to the right. The first spring 26 is compressed. The push plate 27 pushes the bottom upper floor 16 stacked in the stacking compartment 15 through the push hole 17. The upper floor 16 moves to the right through the outlet hole 18 to align with the lower floor 4 and move to the right synchronously. When the first wedge block 28 contacts the second wedge block 29, the first wedge block 29... 8 slides into contact with the second wedge 29, causing the first wedge 28 to retract into the slide 30. The first wedge 28 drives the limiting rod 31 to move, the second spring 32 is compressed, and the L-shaped lever 13 disengages from the first wedge 28. At this time, the bottom upper floor 16 in the stacking compartment 15 disengages from the outlet 18 and falls onto the lower floor 4. It adheres to the lower floor 4 through the adhesive on the lower floor 4. Since the first wedge 28 is no longer restricted by the L-shaped lever 13, the first spring 26 quickly rebounds, causing the push block 24 and push plate 27 to return to their left positions. The push plate 27 disengages. After leaving the stacking bin 15, the remaining stacked upper floorboards 16 in the stacking bin 15 fall down. At the same time, the first wedge block 28 returns to its original position under the rebound of the second spring 32. The glued upper floorboards 16 and lower floorboards 4 continue to move a certain distance on the pallet 11. When they reach the right end of the steel belt of the steel belt machine 1, the steel belt flips over, causing the glued multi-layer floorboards to tip out. The lower floorboards 4 on the next pallet 11 on the left also move to the bottom of the stacking bin 15 and repeat the above steps, thus realizing the continuous non-stop gluing of multiple upper floorboards 16 and lower floorboards 4.

[0022] This invention is simple to operate, convenient to use, and suitable for widespread promotion and application. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
