Description

Technical Field

[0001] This invention relates to the field of adhesive coating equipment technology, specifically to an automatic adhesive coating equipment for composite board production. Background Technology

[0002] The automatic glue application process for composite boards mainly relies on roller conveyors to transport the boards. During processing, glue is applied to the surface of the boards, and multiple layers of boards are bonded together to form a composite board. It is widely used in the processing of various boards such as flooring, decorative boards, and thermal insulation composite boards.

[0003] Existing conventional composite board coating equipment maintains a uniform glue flow rate across the board surface and sides during coating operations, resulting in a completely consistent glue layer thickness. However, the glue filling allowance on the board sides is insufficient, and the gaps between the side edges after board pressing cannot be fully filled with glue. Over long-term use, this can easily lead to quality defects such as side bonding failure, delamination, and edge delamination. Furthermore, traditional coating devices with side thickening coating functions have a fixed thickening area, which cannot adaptively adjust the thickening range according to the actual width of the board. To address this issue, we disclose a coating equipment for automated composite board production. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic glue-applying equipment for composite board production, so as to solve the problems mentioned in the prior art.

The two ends of the outer rods are fixedly installed on the two vertical inner walls of the regulating hole. Two sliders are slidably sleeved on each of the two outer rods. The inner rods are fixedly installed on the sides of the two sliders on the same side. Two springs are sleeved on each of the two outer rods. The two ends of the springs are respectively fixedly installed on the sides of the sliders and the inner wall of the regulating hole.

[0013] As a preferred technical solution, the flow regulating mechanism further includes two horizontal columns. The sides of the two horizontal columns that are close to each other are fixedly installed on the sides of the two sliders that are far apart from each other. Each of the two horizontal columns has a cross-shaped sliding hole at the far end. A cross-shaped sliding column is slidably installed in each of the two cross-shaped sliding holes. The bottom ends of the two rotating rods are rotatably installed on the sides of the two cross-shaped sliding columns. A right-angled triangular block is fixedly installed at the far end of each of the two cross-shaped sliding columns.

[0014] As a preferred technical solution, the width adjustment mechanism further includes two oblique holes opened at the top of the horizontal plate, and extrusion columns are fixedly installed on the top of the two sliding blocks. The two extrusion columns are respectively installed in the two oblique holes. T-shaped slide rails are fixedly installed on both sides of the glue-applying die head.

[0017] As a preferred technical solution, the number of push rods is two, and the distance between the two oblique holes away from the inner wall of the L-shaped plate is less than the distance between the two oblique holes close to the inner wall of the L-shaped plate.

[0018] As a preferred technical solution, there are multiple transverse round rods, and a stop block is fixedly installed at the end of the transverse round rod away from the T-shaped sliding column, and the stop block contacts the side of the U-shaped sliding rod.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] As the glue-applying die passes the edge of the board, this equipment uses a cylindrical extrusion mechanism with a right-angled triangular block to loosen the elastic glue tube in a U-shaped plate. This expansion of the elastic tube increases the glue flow rate, resulting in a thicker glue layer on the sides of the board compared to the center. Compared to traditional glue-applying equipment where the glue layer thickness is uniform across the board surface and sides, this equipment provides more allowance for the side glue layer, ensuring more thorough wetting and filling of the gaps after the composite board is pressed together. This effectively avoids the defect of weak adhesion on the sides of the board, preventing delamination and side glue separation during long-term use, and continuously ensuring the overall structural stability of the composite board.

[0021] In this equipment, a servo motor drives a reverse threaded shaft to adjust the distance between the guide plates on both sides. When the width of the sheet material narrows, the linkage mechanism simultaneously retracts the right-angled triangular block, shortening the distance between the triangular block and the glue-coating die head, and the effective area for thickening the glue coating also narrows. Unlike fixed-width thickening glue coating structures, this equipment can automatically adjust the side thickening range according to the width of the sheet material, avoiding the problem of excessively wide thickening areas and waste of excess glue material on narrow sheets.

[0022] In this equipment, the electric telescopic rod drives the cylinder to move laterally, changing the contact position between the cylinder and the inclined surface of the right-angled triangular block, and adjusting the movement stroke of the triangular block after being compressed, thereby controlling the opening amplitude of the elastic tube and precisely adjusting the thickness of the side adhesive coating. Compared with the adhesive coating structure with a fixed thickness, this equipment can change the thickness of the side adhesive layer as needed, and adjust the thickness of the side adhesive layer for different boards and different bonding strength requirements.

[0035] 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.

[0036] Example: Figures 1-11 As shown, the present invention provides a technical solution for an automatic glue-coating equipment for composite board production. The glue-coating equipment includes an outer roller conveyor 1 and an inner roller conveyor 4 arranged in sequence. A frame 3 is arranged on the outside of the inner roller conveyor 4, and a guide mechanism is installed inside the frame 3.

[0037] Electric slides 5 are installed on the inner walls of both sides of the frame 3. The electric slides 5 are existing technology and include an aluminum profile frame, a servo motor, a coupling, a ball screw, a screw nut, a linear guide, a slider, and a slide base. The servo motor outputs rotational power, which drives the ball screw to rotate continuously through the coupling. The screw nut is rigidly connected to the slide base. The rotation of the screw converts the rotational motion into linear motion, which drives the slide base to translate along the linear guide. The slide base of the electric slides 5 is equipped with a glue-applying mechanism.

[0038] The glue-applying mechanism is equipped with a flow regulation mechanism;

[0039] The guide mechanism is equipped with a width adjustment mechanism, which is installed in conjunction with the flow adjustment mechanism.

[0040] The width adjustment mechanism includes a horizontal plate 16. A lower plate 22 is rotatably mounted on the bottom of the horizontal plate 16 via a push rod 17. A T-shaped hole 23 is opened on one side of the lower plate 22. A T-shaped sliding column 43 is slidably mounted in the T-shaped hole 23. A transverse round rod 44 is fixedly mounted on the side of the T-shaped sliding column 43. A U-shaped sliding rod 45 is slidably sleeved on the transverse round rod 44. Rotating rods 47 are rotatably mounted on both ends of the U-shaped sliding rod 45.

[0041] With the above structure: the guide mechanism can guide and center the board; the glue application mechanism and the electric slide 5 can apply glue to the top of the board; the flow adjustment mechanism can apply thicker glue to the edge of the board; and the width adjustment mechanism can adjust the width of the glue application according to the width of the board.

[0042] like Figures 1-4 As shown, the guiding mechanism includes a servo motor 6 fixedly installed on the side of the frame 3. The output shaft of the servo motor 6 is fixedly installed with a rotating shaft 7. One end of the rotating shaft 7 passes through one side of the frame 3 and is rotatably installed on the other side of the frame 3. The rotating shaft 7 has two oppositely arranged external threads 8. Two guide posts 10 are fixedly installed on both sides of the frame 3. Two sliding blocks 9 are slidably sleeved on the two guide posts 10. The two sliding blocks 9 are respectively threaded onto the two external threads 8. Guide plates 2 are fixedly installed at the bottom of the two sliding blocks 9. The two guide plates 2 are corresponding to the positions of the outer roller conveyor 1 and the inner roller conveyor 4. Two L-shaped sliding columns 15 are fixedly installed on the top of the guide post 10 away from the outer roller conveyor 1. Two positioning rods 24 are fixedly installed on the top of the other guide post 10. The horizontal plate 16 is slidably sleeved on the horizontal end of the two L-shaped sliding columns 15. The lower plate 22 is slidably sleeved on the two positioning rods 24. By starting the servo motor 6, the rotating shaft 7 and the two external threads 8 are rotated. The rotation of the two external threads 8 causes the two sliding blocks 9 and the two guide plates 2 to move closer to each other, so that the plates of different widths can be guided to the middle position. The front ends of the two guide plates 2 are inclined to facilitate the guidance of the plates.

[0043] like Figure 6 and Figure 7 As shown, the glue coating mechanism includes a mounting column 11 fixedly installed on the slide of the electric slide table 5. A glue coating die head 14 is fixedly installed at the bottom of the mounting column 11 through two connecting rods 13. A cavity 30 is opened on the glue coating die head 14. An adjustment hole 25 located below the cavity 30 is opened on the side of the glue coating die head 14. Multiple glue outlet holes 28 are evenly arranged on the top and bottom inner walls of the adjustment hole 25. The multiple glue outlet holes 28 located above are connected to the cavity 30. A glue inlet hole 29 is opened on the inner top wall of the cavity 30. A feed pipe 12 corresponding to the position of the glue inlet hole 29 is fixedly installed on the top of the glue coating die head 14. Multiple elastic glue tubes 31 are fixedly installed on the top and bottom inner walls of the adjustment hole 25. The elastic glue tubes 31 are corresponding to the positions of the glue outlet holes 28. The feed pipe 12 can be connected to the outlet of the glue supply pump via a hose, and the inlet of the pump is connected to the glue tank to realize the delivery of glue. During glue application, the glue is delivered to the feed pipe 12 by the glue supply pump and enters the glue inlet hole 29 and the cavity 30. It is then applied to the top of the board through multiple elastic glue tubes 31 and multiple glue outlet holes 28.

[0044] like Figures 6-8As shown, the flow regulating mechanism includes two outer rods 33 and two inner rods 32. The two ends of the outer rods 33 are fixedly installed on the two vertical inner walls of the regulating hole 25. Two sliders 36 are slidably sleeved on each of the two outer rods 33. The inner rods 32 are fixedly installed on the sides of the two sliders 36 on the same side. Two springs 37 are sleeved on each of the two outer rods 33. The two ends of the springs 37 are respectively fixedly installed on the sides of the sliders 36 and the inner wall of the regulating hole 25. Multiple U-shaped plates 34 are fixedly installed on the sides of the two inner rods 32 that are close to each other. The multiple U-shaped plates 34 are located on the same side of multiple elastic tubes 31. A fixing plate 35 is provided on the other side of each elastic tube 31. The U-shaped plates 34 move with the sliders 36, squeezing the elastic tubes 31. The fixed plate 35 serves as a fixed support, and the sides of multiple fixed plates 35 are fixedly installed on the inner wall of the adjustment hole 25. The positions of multiple U-shaped plates 34 and multiple fixed plates 35 are corresponding. The elastic tube 31 is located between the U-shaped plates 34 and the fixed plates 35. The flow adjustment mechanism also includes two horizontal columns 26. The sides of the two horizontal columns 26 that are close to each other are fixedly installed on the sides of two sliders 36 that are far apart from each other. The ends of the two horizontal columns 26 that are far apart from each other are provided with cross sliding holes 41. Cross sliding columns 48 are slidably installed in the two cross sliding holes 41. The bottom ends of the two rotating rods 47 are rotatably installed on the sides of the two cross sliding columns 48. Right-angled triangular blocks 27 are fixedly installed at the ends of the two cross sliding columns 48 that are far apart from each other. The sheet material is placed on the outer roller conveyor 1, which transports the sheet material to below the glue-applying die head 14. Glue is delivered to the feed pipe 12 by the glue supply pump and enters the glue inlet 29 and cavity 30. It is then applied to the top of the sheet material through multiple elastic glue tubes 31 and multiple glue outlets 28. At this time, the electric slide table 5 starts, causing the mounting column 11, connecting rod 13, glue-applying die head 14, two horizontal columns 26, two cross slide columns 48, and two right-angled triangular blocks 27 to move back and forth. When the glue-applying die head 14 moves rapidly... When the material moves to the edge of one side of the board, one of the right-angled triangular blocks 27 contacts the cylinder 21. The cylinder 21 presses the right-angled triangular block 27 to make it move. The right-angled triangular block 27 drives the cross slide column 48, the horizontal column 26, the two outer rods 33, the four sliders 36, and the multiple U-shaped plates 34 to move. The four springs 37 continue to deform. Since the U-shaped plate 34 separates from the elastic tube 31, the diameter of the elastic tube 31 can be expanded, so that more glue can be leaked out, increasing the amount of glue applied to both sides of the board.

[0045] like Figure 4 , Figure 5 , Figure 10 and Figure 11As shown, the width adjustment mechanism also includes two oblique holes 18 on the top of the horizontal plate 16. Extrusion columns 19 are fixedly installed on the top of each of the two sliding blocks 9, and the two extrusion columns 19 are respectively fitted into the two oblique holes 18. T-shaped slide rails 42 are fixedly installed on both sides of the glue-applying die head 14. Sliding plates 46 are slidably installed on each of the two T-shaped slide rails 42. Rectangular holes are opened on the top of each of the two sliding plates 46, and the two ends of the U-shaped slide rod 45 are respectively slidably installed into the two rectangular holes. The T-shaped slide rails 42 limit the sliding plates 46, allowing them to slide only forward and backward. When the width of the sheet material narrows, the servo motor 6 is activated, causing the rotating shaft 7 and the two external threads 8 to rotate. The rotation of the two external threads 8 causes the two sliding blocks 9 to move closer together. The two sliding blocks 9 moving closer together cause the two extrusion columns 19 to slide within the two oblique holes 18, thereby moving the horizontal plate 16. The movement of the horizontal plate 16 drives the two push rods 17 to rotate, causing the lowering plate 22 to move downwards. The movement of the lowering plate 22... The T-shaped sliding column 43 moves downward, and the movement of the T-shaped sliding column 43 drives the U-shaped sliding rod 45 to move downward through the horizontal round rod 44. The movement of the U-shaped sliding rod 45 drives the two rotating rods 47 to rotate, thereby bringing the two right-angled triangular blocks 27 and the two cross sliding columns 48 closer to each other. The distance between the right-angled triangular blocks 27 and the glue coating die head 14 becomes shorter. Only when the glue coating die head 14 moves closer to the edge of the board can the right-angled triangular blocks 27 contact the round rod 21, thus narrowing the glue coating width of the narrower board.

[0046] like Figure 9 As shown, L-shaped plates 20 are fixedly installed on the sides of the two guide plates 2 that are far apart from each other, and proximity switches 38 are fixedly installed on the sides of the two L-shaped plates 20 that are close to each other. The two proximity switches 38 correspond to the positions of the glue-applying die head 14. An electric telescopic rod 39 is fixedly installed on the side of the L-shaped plate 20. The movable end of the electric telescopic rod 39 passes through the side of the L-shaped plate 20 and is fixedly installed with an adjusting plate 40. A cylinder 21 is fixedly installed on the top of the adjusting plate 40. The position of the cylinder 21 corresponds to the inclined side of the right-angled triangular block 27. The position of the cylinder 21 can be adjusted by the electric telescopic rod 39, so that the position of the cylinder 21 relative to the inclined side of the right-angled triangular block 27 changes, and the movement distance of the right-angled triangular block 27 after being squeezed by the cylinder 21 changes. This allows for the adjustment of different glue-applying amounts to meet the needs of different sheet materials.

[0047] like Figure 10 As shown, the distance between the bottom ends of the two rotating rods 47 is less than the distance between the top ends of the two rotating rods 47. The advantage of this design is that when the U-shaped slide bar 45 moves downward, it can drive the two cross slide bars 48 to move closer to each other.

[0048] like Figure 4As shown, there are two push rods 17. The distance between the two oblique holes 18 away from the inner wall of the L-shaped plate 20 is less than the distance between the two oblique holes 18 close to the inner wall of the L-shaped plate 20. The advantage of this arrangement is that when the two extrusion columns 19 are close to each other, the horizontal plate 16 will be close to the L-shaped plate 20, which makes it easier to adjust the distance between the right-angled triangular block 27 and the glue-applying die head 14 later.

[0049] like Figure 10 As shown, there are multiple transverse round rods 44. A stop is fixedly installed at the end of each transverse round rod 44 away from the T-shaped sliding post 43, and the stop contacts the side of the U-shaped sliding rod 45. The spring 37 is initially in a deformed state, as shown... Figure 8 As shown, the two springs 37 on the left are in a stretched state, and the two springs 37 on the right are in a compressed state. The inner diameter of the elastic tube 31 is smaller than the inner diameter of the dispensing hole 28. With the setting of the stop, the U-shaped slide bar 45 will not continue to move away from the T-shaped slide column 43, so that in the initial state, the multiple U-shaped plates 34 will no longer approach and squeeze the elastic tube 31, so that the elastic tube 31 maintains a minimum flow rate.

[0050] The proximity switch 38, outer roller conveyor 1, inner roller conveyor 4, electric telescopic rod 39 and servo motor 6 of this application can be connected to an external controller, and the electrical components of this application can be connected to an external power source.

[0051] Working principle of the invention:

[0052] In use, the sheet material is placed on the outer roller conveyor 1, which transports the sheet material to below the glue-applying die head 14. Glue is delivered to the feed pipe 12 via the glue supply pump and enters the glue inlet 29 and cavity 30. It is then applied to the top of the sheet material through multiple elastic glue tubes 31 and multiple glue outlet holes 28. At this time, the electric slide table 5 starts, causing the mounting column 11, connecting rod 13, glue-applying die head 14, two horizontal columns 26, two cross slide columns 48, and two right-angled triangular blocks 27 to move back and forth. When the glue-applying die head 14... When the material moves quickly to the edge of one side of the board, one of the right-angled triangular blocks 27 contacts the cylinder 21. The cylinder 21 squeezes the right-angled triangular block 27 to make it move. The right-angled triangular block 27 drives the cross slide column 48, the horizontal column 26, the two outer rods 33, the four sliders 36, and the multiple U-shaped plates 34 to move. The four springs 37 continue to deform. Since the U-shaped plate 34 separates from the elastic tube 31, the diameter of the elastic tube 31 can be expanded, so that more glue can be leaked out, increasing the amount of glue applied to both sides of the board.

[0053] When the width of the sheet becomes narrower, the servo motor 6 is activated to rotate the shaft 7 and the two external threads 8. The rotation of the two external threads 8 causes the two sliding blocks 9 and the two guide plates 2 to move closer to each other. The two sliding blocks 9 move closer to each other, causing the two extrusion columns 19 to slide in the two inclined holes 18 respectively, which in turn causes the horizontal plate 16 to move. The movement of the horizontal plate 16 drives the two push rods 17 to rotate, causing the lower plate 22 to move downward. The movement of the lower plate 22 drives the T-shaped sliding column 43 to move downward. The movement of the T-shaped sliding column 43 drives the U-shaped sliding rod 45 to move downward through the horizontal round rod 44. The movement of the U-shaped sliding rod 45 drives the two rotating rods 47 to rotate, thereby causing the two right-angled triangular blocks 27 and the two cross sliding columns 48 to move closer to each other. The distance between the right-angled triangular blocks 27 and the glue coating die head 14 becomes shorter. When the glue coating die head 14 moves closer to the edge of the sheet, the right-angled triangular blocks 27 can contact the round column 21, making the glue coating width of the narrower sheet narrower.

[0054] By setting two proximity switches 38, when the glue-applying die head 14 moves to the edge of the board, the transmission direction of the electric slide table 5 is changed, thereby changing the movement direction of the glue-applying die head 14 and realizing the back-and-forth glue application to the top of the board. At the same time, the position of the cylinder 21 can be adjusted by the electric telescopic rod 39, so that the position of the cylinder 21 relative to the inclined side of the right-angled triangular block 27 changes, and the movement distance of the right-angled triangular block 27 after being squeezed by the cylinder 21 changes. This allows for the increase of different glue application amounts to meet the needs of different boards.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
