Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of gypsum board edge sealing, and particularly relates to a gypsum board edge sealing mechanism and an edge sealing device. BACKGROUND

[0002] Gypsum board is a kind of light board made of building gypsum as the main raw material, and the edges of the two ends of the gypsum board need to be sealed before leaving the factory. The edge sealing is generally realized by an edge sealing mechanism. An edge sealing mechanism is arranged on each side of the conveying belt conveying the gypsum board. When the gypsum board passes through the edge sealing mechanism, the edge sealing paper tape is pasted on the two ends of the gypsum board by the edge sealing mechanism.

[0003] In the prior art, one side of the edge sealing paper tape is provided with a back adhesive, and a water dipping mechanism is arranged in the edge sealing mechanism to perform water distribution on the surface of the edge sealing paper tape. The back adhesive is wetted by water and has adhesion to be pasted on the end of the gypsum board. For example, the technical solution disclosed in the Chinese invention patent with the application number 202411858780.3 and the application date of December 17, 2024, and the patent name of "automatic edge sealing method and device for gypsum board", and the technical solution disclosed in the Chinese invention patent with the application number 202110593569.3 and the application date of May 28, 2021, and the patent name of "automatic edge sealing device for gypsum board".

[0004] After the traditional edge sealing mechanism directly pastes the edge sealing paper tape on the edge of the gypsum board, the edge sealing paper tape is difficult to remove in subsequent use. To solve this problem, the prior art solution is to set a core paper tape with a width smaller than the edge sealing paper tape, and to paste the core paper tape and the edge sealing paper tape together before edge sealing, and then paste them on the edge of the gypsum board. At this time, the core paper tape is located at the end of the gypsum board. The width of the core paper tape is generally equal to or slightly greater than the thickness of the gypsum board. The surface of the core paper tape does not have a back adhesive, and the toughness of the core paper tape is generally greater than that of the edge sealing paper tape. Therefore, when the core paper tape is pulled to remove it, the edge sealing paper tape is also removed. For example, the technical solution disclosed in the Chinese utility model patent with the application number 200520086685.2 and the application date of August 29, 2005, and the patent name of "automatic edge sealing device for straight-faced gypsum board", and the technical solution disclosed in the Chinese utility model patent with the application number 202121761161.4 and the application date of July 30, 2021, and the patent name of "automatic edge sealing machine for gypsum board".

[0005] However, the existing technology including the above technical solutions has the following defects: the water absorption mechanism is generally realized by a sponge roller, the edge sealing paper strip is in contact with the sponge roller during movement and is extruded, and the water stored in the sponge is extruded and mixed with the adhesive, in this way, the sponge roller is generally rotated under the driving of the edge sealing paper strip, so that the water output is difficult to control, and due to the material of the sponge, a large amount of adhesive is attached to the surface of the sponge roller during continuous contact with the edge sealing paper strip, which affects the subsequent wetting effect of the adhesive on the surface of the edge sealing paper strip, and further affects the edge sealing quality of the gypsum board.

[0026] Figures 1-4 This is the best embodiment of the present invention, Figures 1-4 The utility model is further described.

[0027] like Figure 1 As shown, an edge sealing device for sealing the edges of gypsum boards includes two edge sealing mechanisms 2 arranged opposite to each other. A conveyor belt 1 passes through the two edge sealing mechanisms 2. When a gypsum board to be edge-sealed (not shown) passes through the two edge sealing mechanisms 2 driven by the conveyor belt 1, both sides of the gypsum board respectively contact the edge sealing mechanisms 2, and the edge sealing mechanisms 2 perform edge sealing on the gypsum board.

[0028] Combine Figures 2-3 The edge-banding mechanism 2 includes a horizontally disposed base plate 7, with two edge-banding paper rollers arranged side by side on the surface of the base plate 7: a first edge-banding paper roller 15 and a second edge-banding paper roller 16. The axes of the first edge-banding paper roller 15 and the second edge-banding paper roller 16 are perpendicular to the surface of the base plate 7. Edge-banding paper tape 10 is wound around the first edge-banding paper roller 15 and the second edge-banding paper roller 16, respectively. As the gypsum board is continuously edge-banded, when the edge-banding paper tape 10 on one edge-banding paper roller is exhausted, the edge-banding paper tape 10 on the other edge-banding paper roller can be immediately used to continue the edge-banding operation, thereby ensuring a continuous supply of edge-banding paper tape 10.

[0029] A core paper bank 17 is provided on one side of the two edge paper rollers. The core paper bank 17 is perpendicular to the surface of the bottom plate 7, and the upper edge of the core paper bank 17 is flush with the surface of the bottom plate 7. The core paper belt 19 is drawn out from the core paper bank 17. Figure 4 Two core paper cavities 21 are arranged side by side in the core paper bank 17. Each core paper chamber 21 contains a core paper roller: a first core paper roller 24 and a second core paper roller 25. Core paper tape 19 is wrapped around the surfaces of the first core paper roller 24 and the second core paper roller 25. As the gypsum board edge is continuously banded, when the core paper tape 19 on one core paper roller is exhausted, the core paper tape 19 on the other core paper roller can be immediately used to continue the edge banding process, thus ensuring a continuous supply of core paper tape 19.

[0030] On the other side of the two edge paper rollers, a pressure roller support 12 is erected on the surface of the base plate 7, and a pressure roller 14 is installed on the side of the pressure roller support 12. The edge paper tape 10 and the core paper tape 19 are adhered to each other to form a composite paper tape before moving to the pressure roller 14. When the gypsum board is in contact with the edge sealing mechanism 2 under the drive of the conveying belt 1, the edge of the gypsum board is clamped in the groove on the surface of the pressure roller 14, and at this time the adhered paper tape is adhered to the edge of the gypsum board by the pressure roller 14, completing the edge sealing operation of the gypsum board.

[0031] On the surface of the base plate 7, a pre-bending support 11 is also erected, which is located on the side of the pressure roller support 12. A pre-bending plate 13 is fixed on the surface of the pre-bending support 11, and the output end of the pre-bending plate 13 is connected to the groove on the surface of the pressure roller 14. Before entering the pressure roller 14, the edge paper tape 10 and the core paper tape 19 first pass through the pre-bending plate 13. The upper and lower ends of the pre-bending plate 13 form a pre-bending groove. The width of the edge paper tape 10 is greater than that of the core paper tape 19. When the edge paper tape 10 passes through the pre-bending plate 13, the upper and lower sides of the edge paper tape 10 are pre-bent at the upper and lower ends of the pre-bending plate 13. After pre-bending, the edge paper tape 10 pre-wraps the core paper tape 19 to form a composite paper tape, which then enters the groove of the pressure roller 14 for edge sealing of the gypsum board. Therefore, by providing the pre-bending plate 13, the edge paper tape 10 is bent by the pre-bending plate 13 before the edge sealing of the gypsum board, forming a wrapping structure for the core paper tape 19, so as to improve the accuracy and reliability of the edge sealing of the gypsum board in the subsequent edge sealing process.

[0032] A guide frame 18 is fixed on the surface of the base plate 7, which is located at the outlet of the core paper warehouse 17. The core paper tape 19 first passes through the guide frame 18 after being drawn out. A plurality of core paper guide rollers 3 are arranged on the conveying path of the core paper tape 19, which are located on the outer side of the base plate 7. A core paper guide frame 6 is also provided at the outlet of the last core paper guide roller 3, which is spaced apart from the pre-bending plate 13 and located on the same side of the base plate 7. The outlet of the core paper guide frame 6 is opposite to the inlet of the pre-bending plate 13. After being drawn out from the core paper warehouse 17, the core paper tape 19 changes from a horizontal state to a vertical state under the guidance of the core paper guide rollers 3 and the core paper guide frame 6, and finally enters the pre-bending plate 13.

[0033] A plurality of edge paper guide rollers 20 are also provided on the conveying path of the edge paper tape 10. The edge paper guide rollers 20 are arranged in sequence on the middle part of the base plate 7. The edge paper tape 10 extends to the inlet of the pre-bending plate 13 under the guidance of the plurality of edge paper guide rollers 20, and is located on the inner side of the core paper tape 19, and enters the pre-bending plate 13 together with the core paper tape 19.

[0034] A water distribution mechanism is also arranged between the conveying path of the edge sealing paper tape 10 and the conveying path of the core paper tape 19, and a water tank 8 is arranged on the surface of the bottom plate 7. The water distribution mechanism comprises a water distribution support 22 arranged on one side of the water tank 8, and a driving motor 9 is fixed on the surface of the water distribution support 22. The driving motor 9 is arranged obliquely on the surface of the water distribution support 22. A speed reducer is fixed on the motor shaft of the driving motor 9. The speed reducer changes the transmission direction of the driving motor 9 while reducing the speed. The output shaft of the speed reducer is coaxially fixed with the water distribution roller 23 after penetrating through the water distribution support 22.

[0035] The water distribution roller 23 is a conical roller, and the larger-diameter end thereof is coaxially fixed with the output shaft of the speed reducer. The water distribution roller 23 is arranged obliquely above the bottom plate 7 along with the driving motor 9. Since the water distribution roller 23 is a conical roller, one side of the roller surface of the water distribution roller 23 is parallel to the surface of the bottom plate 7 and is immersed in the water tank 8, and the other side of the roller surface of the water distribution roller 23 is a vertical surface. The vertical surface of the water distribution roller 23 is at an angle (or perpendicular) to the bottom plate 7. The edge sealing paper tape 10 is in contact with the vertical surface of the water distribution roller 23 during the conveying process. Therefore, the water distribution roller 23 continuously applies water in the water tank 8 to the surface of the edge sealing paper tape 10 during the rotation process. The amount of water applied to the surface of the edge sealing paper tape 10 can be changed by controlling the rotation speed of the water distribution roller 23. The water distribution roller 23 is a hard roller, which avoids the problem that the amount of water cannot be controlled when a sponge roller is used for water distribution in the prior art.

[0036] A cylinder support 4 is also arranged on one side of the water distribution support 22, and a jacking cylinder 5 is fixed on the surface of the cylinder support 4. The piston rod of the jacking cylinder 5 is opposite to the side of the edge sealing paper tape 10. When the edge sealing process of the gypsum board needs to be temporarily interrupted, the jacking cylinder 5 is actuated, and the piston rod of the jacking cylinder 5 is output to move the edge sealing paper tape 10 away from the water distribution roller 23. This avoids the problem that the water on the surface of the water distribution roller 23 excessively soaks the edge sealing paper tape 10 when the edge sealing paper tape 10 is always in contact with the water distribution roller 23, which causes the strength of the edge sealing paper tape 10 to decrease and even break.

[0037] The specific working process and working principle are as follows:

[0038] After the edge sealing paper tape 10 and the core paper tape 19 form a composite paper tape in the pre-bending plate 13, they enter the groove on the surface of the compression roller 14 and are in contact with the gypsum board which also enters the groove of the compression roller 14. The gypsum board is moved under the driving of the conveying belt 1, and the edge sealing process is completed in the compression roller 14 at the same time. The edge sealing paper tape 10 and the core paper tape 19 are provided with conveying power.

[0039] The edge sealing paper tape 10 is output from the surface of the edge sealing paper roll, and is guided by the plurality of edge sealing paper guide rollers 20 to the entrance of the pre-bending plate 13 during the running process, and the edge sealing paper tape 10 passes through the surface of the water distribution roller 23 during the conveying process, the water distribution roller 23 is driven to rotate by the driving motor 9, and the water in the water tank 8 is continuously applied to the surface of the edge sealing paper tape 10 during the rotation process, and the back adhesive layer on the surface of the edge sealing paper tape 10 is wetted, so that the back adhesive layer on the surface of the edge sealing paper tape 10 has adhesion.

[0040] The core paper tape 19 is output from the core paper warehouse 17, and is guided by the guide frame 18, the core paper guide roller 3 and the core paper guide frame 6 to the entrance of the pre-bending plate 13, and is attached to the edge sealing paper tape 10, at this time, since the back adhesive layer on the surface of the edge sealing paper tape 10 has been wetted and has adhesion, the core paper tape 19 is attached to the middle part to form a composite paper tape.

[0041] The composite paper tape seals the edge of the gypsum board after entering the groove on the surface of the pressure roller 14, at this time, the core paper tape 19 is attached to the edge of the gypsum board, and the edge sealing paper tape 10 is attached to the upper and lower surfaces of the edge of the gypsum board by using the back adhesive layer on the surface, and the edge sealing is completed.

[0042] The above is only a preferred embodiment of the present application, and is not a limitation on other forms of the present application, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments. However, any simple modification, equivalent change and modification of the above embodiments without departing from the technical content of the present application, according to the technical essence of the present application, still belongs to the protection scope of the present application.
