Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production, and in particular to an edge banding and rolling cutting device for gypsum board production. Background Art

[0002] Gypsum board is a building board made of building gypsum as the main raw material, mixed with appropriate amounts of additives and fiber materials, and made through mixing, molding, condensation and drying. It has many excellent properties such as light weight, high strength, fire resistance, heat insulation, and sound absorption, and is widely used in the field of building decoration. The main component of gypsum board is building gypsum, which has a certain degree of water absorption. When the gypsum board is placed in a humid environment, the gypsum board will absorb moisture, resulting in a decrease in its own strength. In order to prevent moisture from entering the interior of the gypsum board from the edge, the gypsum board needs to be edge-sealed at the cut position after molding and cutting to prevent the gypsum board from absorbing water and affecting its strength and service life.

[0003] For example, the patent with publication number CN118418293A and publication date August 2, 2024 discloses an automatic edge banding machine for gypsum boards used in the production of environmentally friendly gypsum boards, including a conveyor belt, and functional side walls are provided on both sides of the conveyor belt, on which a power structure, a bonding structure, an edge banding structure and a residual material processing structure are respectively installed; when using the automatic edge banding machine for gypsum boards in this patent, the edge banding machine adopts a method of spraying hot melt adhesive for edge banding. First, the edge banding structure provided in the edge banding machine includes the functions of grinding and wiping. During the edge banding process, the edge surface is cleaned to adapt to the edge banding use of various gypsum boards. At the same time, in conjunction with the power structure, the edge banding is performed in a mobile conveying manner to perform automatic edge banding. During grinding and wiping, in order to improve efficiency and quality, a bonding structure is also provided to assist in grinding and wiping. After the edge banding is completed, a residual material processing structure is also provided to process the excess material of the edge banding, so that the quality of the edge banding is guaranteed after the edge banding is completed.

[0004] When the existing edge banding is adhered to the side wall of the gypsum board, in order to ensure that the glue can fully infiltrate all parts of the edge banding that contact the gypsum board and make the edge banding firmly adhere to the gypsum board, the glue coating equipment usually sprays a slightly excessive amount of slurry onto the surface of the edge banding. When the edge banding and the gypsum board are subsequently pressed together, the glue between the gypsum board and the edge banding is squeezed and usually overflows onto the upper surface of the gypsum board and the conveyor belt below. The glue on the upper surface of the gypsum board can be removed by manual scraping, but the glue on the conveyor belt is not easy to remove due to the obstruction of the gypsum board and the fact that it is in a moving state. The glue on the conveyor belt is also easy to adhere to the bottom of the next board to be edge-sealed and form glue spots on the bottom of the gypsum board, affecting the appearance quality of the gypsum board.

[0029] In order to make those skilled in the art better understand the technical solution of the present invention, Figure 1-8 , the present invention is further introduced in detail.

[0030] In each embodiment of the present invention, for the convenience of description and understanding, the conveying direction of the conveyor frame 1 is called the length direction, the direction perpendicular to the length direction on the horizontal plane is called the width direction, and the direction of gravity is called the vertical direction, that is, the length direction, width direction and vertical direction constitute a three-dimensional rectangular coordinate system.

[0031] An embodiment of the present invention provides an edge banding and rolling cutting device for gypsum board production, comprising a conveyor frame 1 for conveying gypsum boards 7, the conveyor frame 1 being provided with a tensioning tray 2, a gluing mechanism 3, a guide wheel group 4 and a pressing mechanism 5, the tensioning tray 2 being wound with an edge banding tape 6, the edge banding tape 6 being guided by the guide wheel group 4 through the gluing mechanism 3 for gluing, and then being pressed onto the side wall of the gypsum board 7 by the pressing mechanism 5, and further comprising a guide strip 8 installed on the conveyor frame 1, the guide strip 8 guiding the bottom end of the edge banding tape 6 to first abut against the bottom end of the gypsum board 7, the pressing mechanism 5 comprising a driving part and a pressing part 51, the driving part driving the pressing part 51 to push the edge banding tape 6 from bottom to top to adhere to the gypsum board 7, and when observed with the naked eye, the edge banding tape 6 forms an inclined bonding track from bottom to top with the gypsum board 7.

[0032] Specifically, the conveying frame 1 is composed of a rectangular seat-shaped frame and a conveying mechanism, the frame is placed horizontally on the ground, and the conveying mechanism is installed on the frame, wherein the conveying mechanism can be selected from a belt conveyor, a chain conveyor, a roller conveyor, etc. In this embodiment, a roller conveyor can be selected, and the roller conveyor conveying the gypsum board 7 is a prior art, and its principle is not repeated; the edge band 6 is in the shape of a long strip, and the height of the edge band 6 is adapted to the thickness of the gypsum board 7, wherein the tensioning tray 2 is composed of a tray body and a spring tensioning device, and the tray body is installed On the frame of the conveyor frame 1, the edge band 6 is wrapped around the tray body, and the other end of the edge band 6 needs to be adhered to the side wall of the gypsum board 7. As the edge banding process of the gypsum board 7 proceeds, the spring tensioning device is used to keep the edge band 6 in a tensioned state to improve the bonding effect between the edge band 6 and the gypsum board 7. The technology of tensioning the tensioning tray 2 for tensioning the edge band 6 is existing technology, and its principle is not repeated here. The guide wheel group 4 is composed of a plurality of wheel bodies, and the plurality of wheel bodies are vertically arranged and rotatably mounted on the conveyor frame 1. The wheel body is used to guide the edge band 6 , so that the edge banding 6 can be attached to the side of the gypsum board 7, the gluing mechanism 3 is composed of a glue spray nozzle and a glue storage box, the glue storage box is installed on the conveying frame 1, the glue spray nozzle is facing the surface where the edge banding 6 and the side of the gypsum board 7 are combined, as the edge banding 6 passes the position of the glue spray nozzle, the glue spray nozzle applies glue to the surface of the edge banding 6, the pressing mechanism 5 is located downstream of the gluing mechanism 3, the existing pressing mechanism 5 usually uses a columnar pressing wheel, which is vertically arranged and rotatably installed on the conveying frame 1, and the pressing wheel is located on the gypsum board. The side of the board 7, when the side wall of the gypsum board 7 needs to be edge-sealed, the edge band 6 tightened by the tensioning tray 2 passes through the guide wheel group 4 and the gluing mechanism 3 and is attached to the side wall of the gypsum board 7. When the edge band 6 passes through the gluing mechanism 3, the gluing mechanism 3 sprays glue on the side of the edge band 6 that is about to be attached to the gypsum board 7. As the conveying frame 1 conveys the gypsum board 7, the gypsum board 7 passes through the pressing wheel with the edge band 6, and the pressing wheel presses the edge band 6 so that the edge band 6 is attached to the side wall of the gypsum board 7, completing the edge banding treatment of the gypsum board 7.

[0033] The disadvantage of the existing technology is that when the existing gluing mechanism 3 sprays glue onto the edge banding 6, in order to ensure that the glue can fully infiltrate all parts of the edge banding 6 that contact the gypsum board 7 (including some places where there may be small gaps or uneven areas), increase the actual bonding area between the resolution tape and the gypsum board 7, and enable the edge banding 6 to adhere firmly to the gypsum board 7, the gluing mechanism 3 usually sprays a slightly excessive amount of glue onto the surface of the edge banding 6. When the pressing wheel presses the gypsum board 7 and the edge banding 6, the excess glue between the gypsum board 7 and the edge banding 6 is squeezed by the pressing wheel and usually overflows onto the upper surface of the gypsum board 7 and the surface of the conveying mechanism below. The glue on the upper surface of the gypsum board 7 forms glue droplets after cooling, resulting in a decrease in the adhesion between the gypsum board 7 and the putty and paint. The glue on the conveyor belt easily adheres to the bottom of the next gypsum board 7 to be edge-sealed, and forms glue spots on the bottom of the gypsum board 7, affecting the appearance quality of the gypsum board 7.

[0034] In order to solve the above problems, in the present embodiment, the guide strip 8 is in the shape of a long strip as a whole, wherein the distance between the bottom end of the guide strip 8 and the bottom end of the side edge of the gypsum board 7 gradually decreases along the length direction, and at the same time, the angle between the side of the guide strip 8 and the side of the gypsum board 7 is also gradually decreasing. In this way, after the edge band 6 and the gypsum board 7 pass through the guide strip 8, the bottom end of the edge band 6 is squeezed by the guide strip 8 to adhere to the bottom end of the gypsum board 7, but the remaining area of ​​the edge band 6 is not squeezed by the guide strip 8 and is in a separated state from the gypsum board 7. When the gypsum board 7 and the edge band 6 pre-treated by the guide strip 8 pass through the position of the pressing mechanism 5, the driving part starts to work, and the driving part drives the pressing part 51 to push the edge band 6 from bottom to top along the oblique line to adhere to the side wall of the gypsum board 7. In the embodiment, the inclined direction of the oblique line refers to an upward inclination along the length direction. By pushing the edge banding 6 from the bottom to the top and obliquely, the air can move upward along the edge banding 6 and be discharged, just like squeezing an air bag with an opening at the top from the bottom to the top, thereby making the adhesion between the edge banding 6 and the gypsum board 7 tighter, and as the pressing portion 51 pushes the edge banding 6 from the bottom to the top along the oblique line to adhere to the side wall of the gypsum board 7, the glue is subjected to the shear force and moves upward along the adhesion direction of the edge banding 6 until it overflows from the gypsum board 7 and the upper edge of the edge banding 6, reducing or even avoiding excess glue from the lower end of the gypsum board 7 to overflow onto the conveying rack 1. When the conveying rack 1 subsequently conveys the gypsum board 7, the glue on the conveying rack 1 sticks to the bottom surface of the gypsum board 7 and forms a glue spot at the bottom of the gypsum board 7, affecting the appearance quality of the gypsum board 7.

[0035] Preferably, the pressing part 51 includes a rotating cylinder 511, which is connected to the conveying end of the driving part. A spiral piece 512 is provided on the side wall of the rotating cylinder 511. Based on the rotation of the rotating cylinder 511, the extrusion trajectory of the spiral piece 512 on the edge banding 6 spirally rises to form the above-mentioned form of extruding the edge banding 6 from bottom to top; a flexible sleeve 513 is provided on the outer ring of the spiral piece 512, and the flexible sleeve 513 is used to directly extrude the edge banding 6.

[0036] Specifically, in this embodiment, the rotating cylinder 511 is vertically arranged and located on the outside of the gypsum board 7. The driving part is a driving motor, which is fixedly mounted on the conveying frame 1 (the driving part is not shown in the figure). The driving end of the driving motor is connected to the bottom end of the rotating cylinder 511. The driving motor is used to drive the rotating cylinder 511 to rotate. It should be noted that the spiral pieces 512 on the rotating cylinder 511 are arranged relatively densely; and in this embodiment, the flexible sleeve 513 is made of rubber material, so that it can be deformed. The flexible sleeve 513 is also spiral-shaped. The flexible sleeve 513 is sleeved on the outer ring of the spiral piece 512. The flexible sleeve 513 increases the radial size of the spiral piece 512 (the flexible sleeve 513 at this time is equivalent to the extension of the outer ring of the spiral piece 512). When it is necessary to press the edge band 6 and the gypsum board 7, as the conveying frame 1 is transported, the gypsum board 7 passes through the pressing process with the edge band 6. In the area of ​​mechanism 5, the driving motor starts working at this time, and the driving motor drives the rotating cylinder 511 to rotate, and the rotating cylinder 511 drives the spiral piece 512 to rotate. When the spiral piece 512 rotates, the spiral piece 512 is similar to a continuous inclined plane. The spiral piece 512 (the flexible sleeve 513) continuously pushes the edge banding 6 upward to adhere to the side wall of the gypsum board 7. Under the action of the spiral piece 512, the glue is subjected to the shear force and moves upward along the adhesion direction of the edge banding 6 until it overflows from the gypsum board 7 and the upper edge of the edge banding 6, thereby preventing excess glue from overflowing from the lower end of the gypsum board 7 onto the conveyor frame 1. In addition, because the flexible sleeve 513 is provided on the outer ring of the spiral piece 512, when the flexible sleeve 513 is squeezed onto the edge banding 6, the flexible sleeve 513 is deformed, so that the contact between the flexible sleeve 513 and the edge banding 6 changes from the initial continuous point contact to the current continuous line contact, so that the edge banding 6 and the gypsum board 7 are more tightly bonded, thereby improving the pressing effect.

[0037] Obviously, after the gypsum board 7 and the edge band 6 are edge-sealed by the pressing mechanism 5, excess glue between the gypsum board 7 and the edge band 6 will overflow from the upper edge of the gypsum board 7. The overflowed glue needs to be cleaned up in time, otherwise, after the glue cools down, glue stains will form on the surface of the gypsum board 7. When the gypsum board 7 is used subsequently, the glue stains on the surface of the gypsum board 7 will cause the adhesion between the gypsum board 7 and the putty and paint to decrease, thereby affecting the use of the gypsum board 7.

[0038] In order to solve the above problem, in this embodiment, a plurality of scrapers 9 are provided at the top of the rotating cylinder 511 , and the scrapers 9 are used to scrape off the glue overflowing onto the surface of the gypsum board 7 .

[0039] Specifically, in this embodiment, the scraper 9 is in the shape of an elongated strip, and a plurality of the scraper plates 9 are arranged at intervals along the circumference of the rotating cylinder 511, wherein one end of the scraper plate 9 is fixedly mounted on the rotating cylinder 511, and the other end of the scraper plate 9 extends outward. When the gypsum board 7 passes through the rotating cylinder 511 with the edge banding 6, the spiral sheet 512 and the flexible sleeve 513 on the rotating cylinder 511 press the gypsum board 7 and the edge banding 6 together to complete the edge banding process (the specific steps of edge banding are the same as above and are not repeated here). As the edge banding 6 is pressed onto the side wall of the gypsum board 7, the glue overflows from the upper edge of the gypsum board 7. At this time, as the rotating cylinder 511 rotates, the scraper plate 9 rotates synchronously with the rotating cylinder 511, and the scraper plate 9 scrapes off the glue on the surface of the gypsum board 7 to prevent the glue from cooling on the surface of the gypsum board 7 to form glue stains, which affects the subsequent use of the gypsum board 7.

[0040] Obviously, since the scraper plate 9 is fixedly mounted on the rotating cylinder 511, and the rotating cylinder 511 rotates continuously under the action of the driving part, after the scraper plate 9 completes the scraping of the glue on the surface of the gypsum board 7, as the rotating cylinder 511 continues to rotate, the scraper plate 9 carries the glue away from the upper surface of the gypsum board 7, and due to the rotation of the scraper plate 9, the glue is easily thrown onto the conveying rack 1, causing the conveying rack 1 to be contaminated by the glue. When the contaminated conveying rack 1 subsequently conveys the gypsum board 7, the glue is easily adhered to the surface of the gypsum board 7, affecting the subsequent use of the gypsum board 7.

[0041] In order to solve the above problem, a avoidance groove 91 is provided on the bottom end of the scraper 9 (that is, the end close to the gypsum board 7), and a storage portion 10 is provided in the avoidance groove 91. The storage portion 10 is used to store the glue on the surface of the gypsum board 7. The storage portion 10 includes a glue collection strip 101. The glue collection strip 101 is provided with a glue collection groove 102. Based on the movement of the scraper 9, the glue collection groove 102 on the glue collection strip 101 collects the glue on the upper surface of the gypsum board 7; the glue collection strip 101 is rotatably connected to the scraper 9 through a first rotating shaft, and the first rotating shaft and the scraper 9 are connected through a torsion spring (the first rotating shaft and torsion spring are not shown in the figure).

[0042] Specifically, the avoidance groove 91 is a rectangular groove. When the glue collecting strip 101 is located on the upper surface of the gypsum board 7, the upper surface of the gypsum board 7 abuts against the glue collecting strip 101, the torsion spring is deformed and accumulates elastic potential energy. The notch of the glue collecting groove 102 on the glue collecting strip 101 is parallel to the board surface of the gypsum board 7, which is convenient for collecting the glue on the upper surface of the gypsum board 7. When the glue collecting strip 101 leaves the upper surface of the gypsum board 7, the torsion spring releases the accumulated elastic potential energy, and the notch of the glue collecting groove 102 on the glue collecting strip 101 faces upward, preventing the glue entering the glue collecting strip 101 from flowing out of the glue collecting groove 102; and because the notch of the glue collecting groove 102 of the glue collecting strip 101 faces upward, the bottom end of the glue collecting strip 101 protrudes from the lower end surface of the scraper plate 9. When the scraper plate 9 follows the rotating cylinder 511 to rotate and hits the gypsum board 7 again, the bottom end of the glue collecting strip 101 is squeezed by the gypsum board 7, and the glue collecting strip 101 rotates around the first rotating axis, so that the glue collecting groove 102 of the glue collecting strip 101 is parallel to the board surface of the gypsum board 7, completing the cycle, and again as the glue collecting strip 101 rotates, the glue on the surface of the gypsum board 7 is scraped off, and the scraped glue enters the glue collecting groove 102 to complete the collection and processing of the glue. When the glue collecting strip 101 follows the scraper plate 9 to separate from the gypsum board surface, the torsion spring releases the accumulated elastic potential energy, and the torsion spring drives the scraper plate 9 and the glue collecting strip 101 to rotate ninety degrees around the first rotating axis. At this time, the notch of the glue collecting groove 102 is facing upward, preventing the glue in the glue collecting groove 102 from flowing out of the glue collecting groove 102, causing contamination of the conveying rack 1.

[0043] Obviously, when the glue collecting strip 101 containing glue passes over the surface of the gypsum board 7 again to scrape glue, the glue collecting groove 102 on the glue collecting strip 101 will rotate again. If too much glue accumulates, the glue in the glue collecting groove 102 may flow to the surface of the gypsum board 7. If there is less glue in the glue collecting groove 102, the glue on the surface of the gypsum board 7 can be cleaned up by the glue collecting strip 101 collecting glue again. However, if there is more glue in the glue collecting groove 102, when the glue collecting strip 101 collects glue again, under the push of the glue collecting strip 101, excessive glue will easily overflow from the edge of the glue collecting strip 101, contaminating the middle area of ​​the gypsum board 7, thereby affecting the quality of the gypsum board 7.

[0044] In order to solve the above problems, the glue collecting groove 102 consists of a glue feeding section 104 located at the groove mouth and a glue collecting section 103 located at the bottom of the groove. The cross-section of the glue feeding section 104 is a right-angled trapezoid, and the narrow end of the glue feeding section 104 is connected to the glue collecting section 103; a pulling plate 11 is provided in the glue collecting groove 102, and a sliding rod 12 is fixedly installed at the bottom of the pulling plate 11. The sliding rod 12 passes through the glue collecting strip 101, and the sliding rod 12 is dynamically sealed to the glue collecting strip 101. The bottom of the glue collecting section 103 is connected to the pulling plate 11 through a first spring 13, and the end of the sliding rod 12 away from the pulling plate 11 is hemispherical; a shielding portion 14 is provided at the connection position between the glue feeding section 104 and the glue collecting section 103, and the shielding portion 14 is used to prevent the glue entering the glue collecting section 103 from re-entering the glue feeding section 104.

[0045] Specifically, in the present embodiment, since the cross section of the glue feeding section 104 is in the shape of a right-angled trapezoid, the glue feeding section 104 includes an upper bottom, a lower bottom, a height (straight side) and a bevel side, wherein the upper bottom refers to the end with a smaller groove pitch, that is, the narrow end in the present embodiment, and the narrow end is connected to the glue receiving section 103, wherein the lower bottom refers to the end with a larger groove pitch, which can also be called the wide end, which is also the notch of the glue feeding section 104, and the end of the bevel side of the glue feeding section 104 away from the glue receiving section 103 abuts against the surface of the gypsum board 7, so as to facilitate the glue liquid to enter the glue receiving groove 102, and, in the present embodiment, one end of the pulling plate 11 abuts against the On the straight side of the glue feeding section 104, the end of the pulling plate 11 close to the oblique side is retractable (this can be achieved by providing a movable sleeve on the outer side of the end of the pulling plate 11 close to the oblique side, and the sliding sleeve and the pulling plate 11 are connected by a second spring). When the notch of the glue collecting groove 102 is parallel to the board surface of the gypsum board 7, the first spring 13 deforms to accumulate elastic potential energy. At this time, the pulling plate 11 is located near the notch of the glue collecting groove 102, and the second spring connected to the movable sleeve on the pulling plate 11 is also in a stress-free state. At this time, the sliding sleeve is spaced apart from the oblique side of the glue feeding section 104. When the notch of the glue collecting groove 102 is arranged upward, the first spring 13 is not stressed, and the pulling plate 11 is located at the position where the glue collecting groove 102 is located. In the glue collecting section 103, the movable sleeve on the outer side of the pulling plate 11 is against the inner wall of the glue collecting section 103. It should be noted that when the movable sleeve follows the pulling plate 11 to move to the intersection of the glue feeding section 104 and the glue collecting section 103, the movable sleeve has already been against the oblique side of the glue collecting groove 102, and it is not that the movable sleeve follows the pulling plate 11 to move to the intersection of the glue feeding section 104 and the glue collecting section 103 before it is against the oblique side of the glue collecting groove 102; wherein, the shielding part 14 is composed of a shielding plate 141, a second rotating shaft 142 and a torsion spring, and the shielding plate 141 is rotatably connected to the glue collecting groove 102 through the second rotating shaft 142, and the second rotating shaft 142 and the glue collecting groove 102 are connected. The shielding plate 141 is connected to the rubber section 103 by a torsion spring (not shown in the figure). When the torsion spring is not under force, the shielding plate 141 is perpendicular to the groove wall of the rubber section 103. At this time, the end of the shielding plate 141 close to the rubber section 104 is blocked, so that the shielding plate 141 cannot deflect toward the rubber section 104. In addition, the bottom surface of the shielding plate 141 is inclined, and the upper end surface of the movable sleeve is also inclined. When the movable sleeve follows the pulling plate 11 from the rubber section 103 to the rubber section 104, the two inclined surfaces between the movable sleeve and the shielding plate 141 squeeze each other, causing the movable sleeve to move on the pulling plate 11 (the cooperation between the movable sleeve and the shielding plate 141 is similar to a wedge cooperation, and its principle is not described in detail);When the glue collecting strip 101 scrapes the glue on the surface of the gypsum board 7, as the rotating cylinder 511 rotates, the glue collecting strip 101 follows the scraper 9 to move to the surface of the gypsum board 7. At this time, the glue collecting groove 102 of the glue collecting strip 101 is parallel to the board surface of the gypsum board 7, and the oblique side of the glue feeding section 104 of the glue collecting groove 102 is away from the end of the glue feeding section 103 against the surface of the gypsum board 7. As the scraper 9 moves, the glue on the surface of the gypsum board 7 enters the glue feeding section 104. Afterwards, as the rotating cylinder 511 rotates, the scraper 9 is separated from the surface of the gypsum board 7, and the torsional member connected to the first rotating shaft is rotated. The spring releases the accumulated elastic potential energy, causing the scraper plate 9 and the glue collecting strip 101 to rotate ninety degrees around the first rotation axis, and the notch of the glue collecting groove 102 faces upward. As the glue collecting strip 101 rotates, the slide bar 12 also separates from the surface of the gypsum board 7. Under the action of the first spring 13, the pulling plate 11 moves toward the glue collecting section 103. During the movement of the pulling plate 11, the movable sleeve on the pulling plate 11 abuts against the oblique side of the glue collecting groove 102. As the pulling plate 11 continues to move toward the glue collecting section 103, the movable sleeve will scrape the glue liquid received in the glue feeding section 104 and mainly located on its oblique side into the glue collecting section 103. Before the glue liquid enters the glue collecting section 103, the glue liquid will pass through the position of the shielding part 14. As the pulling plate 11 is squeezed, the shielding plate 141 of the shielding part 14 rotates to avoid the pulling plate 11. The pulling plate 11 brings the glue liquid into the glue collecting section 103 to complete the collection process of the glue liquid. When the glue collecting strip 101 follows the rotating cylinder 511 to move to the surface of the gypsum board 7 again, under the squeezing of the gypsum board 7, the glue collecting strip 101 rotates ninety degrees around the first rotating axis, so that the glue collecting groove 102 of the glue collecting strip 101 is parallel to the board surface of the gypsum board 7 again. When the glue collecting strip 101 rotates, the sliding rod 12 on the glue collecting strip 101 is scraped. The sliding rod 12 moves the pull plate 11 toward the notch of the glue collecting groove 102 due to the squeezing of the glue sheet 9. When the pull plate 11 passes the shielding plate 141, the shielding plate 141 cannot deflect toward the glue feeding section 104. At this time, the movable sleeve on the pull plate 11 moves relative to avoid the shielding plate 141, allowing the pull plate 11 to pass through the shielding plate 141. At this time, due to the obstruction of the shielding plate 141, the glue in the glue collecting section 103 cannot re-enter the glue feeding section 104. Instead, it returns to the surface of the gypsum board 7 along the oblique side of the glue feeding section 104, thereby preventing the surface of the gypsum board 7 from being re-contaminated by the collected glue.

[0046] Obviously, as the amount of glue inside the glue collecting tank 102 gradually increases, the staff needs to regularly clean the glue inside the glue collecting tank 102 to ensure that the glue collecting strip 101 can continuously collect the glue overflowing onto the surface of the gypsum board 7. In order to ensure the continuity of the edge sealing of the gypsum board 7, a suction pipe can also be connected to the side wall of the glue collecting strip 101, and the other end of the suction pipe is connected to a suction pump. The glue in the glue collecting tank 102 is extracted and collected by the suction pump to complete the cleaning of the glue inside the glue collecting tank 102. Among them, sucking the glue in a container (that is, the glue collecting tank 102 in this embodiment) by a suction pump and a pipe is an existing technology, and its principle will not be repeated.

[0047] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
