Description

Technical Field

[0001] This invention belongs to the field of building material processing technology, specifically a glue application device for composite board processing. Background Technology

[0002] PU composite board is an excellent energy-saving insulation material with good heat insulation, fire resistance and heat preservation properties. It can be widely used in various buildings to play a good role in heat preservation.

[0003] The structure of a PU composite board mainly includes an upper layer, a lower layer, a middle layer, and side layers. During processing, the upper and lower layers need to be coated with adhesive to ensure the bonding strength with the middle foam layer. Generally, adhesive is applied evenly using a splattering method. This involves setting up a rotating disc, with an adhesive injection pipe installed above the disc. The adhesive is sprayed onto the disc, and as the disc rotates, it spreads the adhesive outwards to achieve even distribution. While this method can achieve uniform adhesive distribution, it is only suitable for the lower layer. The composite boards produced by our company also require adhesive to be applied to the upper layer, making the splattering method practically impossible. Furthermore, with splattering, the adhesive spreads outwards and doesn't all land on the lower layer, resulting in significant adhesive waste. Therefore, a coating device that facilitates adhesive application to the upper layer and reduces adhesive waste is needed. Summary of the Invention

[0004] To address the above problems, this invention provides an adhesive application device for composite board processing, which applies adhesive to the upper surface layer and recycles the adhesive, thereby reducing adhesive waste.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a glue application device for composite board processing, comprising a movable frame assembly, a cover rotatably disposed on the movable frame assembly, a spraying cylinder rotatably disposed inside the cover, and a plurality of fine holes penetrating both inside and outside the spraying cylinder;

[0006] The spraying cylinder is equipped with a rotating injection tube for injecting glue;

[0007] A collection box for collecting glue is installed at the bottom of the cover.

[0008] As a further improvement to the above solution, the enclosure includes a first sealing part, a second sealing part, and a third sealing part;

[0009] The second closed section protrudes downwards, and the spraying cylinder is located inside the second closed section. The bottom of the second closed section is provided with a discharge port for discharging glue.

[0010] As a further improvement to the above scheme, an inclined surface transition is adopted between the second closed section and the third closed section.

[0011] As a further improvement to the above solution, a baffle plate is rotatably provided inside the spraying cylinder to surround the injection pipe portion, and a sealing strip is provided between the two sides of the baffle plate and the inner wall of the spraying cylinder.

[0012] As a further improvement to the above solution, the rotating shaft of the blocking plate and the rotating shaft of the spraying cylinder are rotatably sleeved together, and the injection pipe is inserted into the blocking plate and fixed to the blocking plate.

[0013] The rotating shaft of the blocking plate is equipped with a fixing component that secures the blocking plate and the cover to each other.

[0014] As a further improvement to the above solution, a handle is also fixedly installed on the rotating shaft of the blocking plate to adjust its position by rotating the blocking plate.

[0015] As a further improvement to the above solution, several vertical rods are provided above the movable frame assembly and the cover, and several support wheels are rotatably provided on the vertical rods to support the upper side plate for transmission. Support pads that contact the upper side plate are provided at the edges of the support wheels.

[0016] As a further improvement to the above scheme, a support roller group is fixedly installed between the two vertical rods to support the upper side plate. The support roller group is located above the upper side plate and corresponds to the position of the cover.

[0017] As a further improvement to the above solution, the movable frame assembly includes a movable seat, and a guide rail assembly is movably arranged below the movable seat. The guide rail assembly is fixedly arranged with the frame for transporting the lower side plate.

[0018] A lifting seat is provided above the movable seat. Several connecting rods are hinged between the lifting seat and the movable seat. The top of the lifting seat is hinged to the cover.

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

[0020] The spray nozzle allows glue to be injected into the injection tube, and then the nozzle is rotated to centrifugally throw the glue onto the upper side panel, thus applying glue to the upper surface. The spray nozzle is arranged horizontally, allowing the glue to be applied to the upper side panel over the largest possible area. The cover can simply seal the spray nozzle, reducing glue spillage during application. Furthermore, the cover can collect any glue that is not applied to the upper side panel, reducing glue waste.

[0021] By using a baffle plate, the position of the adhesive dispensing tube can be changed. The baffle plate can hold the adhesive, and the part of the tube above the baffle plate can throw the adhesive out, while the part of the tube below the baffle plate can be cleaned by the sealing strip during rotation, effectively isolating the adhesive from leakage from below. When stopping the application, the baffle plate can be moved to a concave-down position by turning the handle. This allows the adhesive on the baffle plate to fall off, and the sealing strip can scrape the inner wall of the tube to remove any residual adhesive from the injection pipe, preventing blockages and sticking.

[0022] The support wheels and support pads can support and transport the upper side plate, and also provide a smaller contact area during the support process, preventing the glue on the upper side plate from sticking together and affecting the uniformity of the glue. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below with reference to embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0032] Please see Figure 1-7 In one specific embodiment, a glue-applying device for processing composite panels includes a movable frame assembly 10, which can be referred to in the attached document. Figure 1 The movable frame assembly 10 is specifically set between the upper side plate 80 and the lower side plate 81. A cover 11 is rotatably set on the movable frame assembly 10. A spraying cylinder 12 is rotatably set inside the cover 11. A motor is connected to the spraying cylinder 12. The motor is fixed to the outside of the cover 11. Several fine holes 121 penetrating inside and outside are provided on the spraying cylinder 12.

[0033] An injection pipe 13 for injecting glue is rotatably installed inside the spraying cylinder 12. The injection pipe 13 is connected to a storage tank for storing glue. Specifically, when applying glue, the glue is introduced into the spraying cylinder 12 through the injection pipe 13. The motor drives the spraying cylinder 12 to rotate, and the glue in the spraying cylinder 12 will move outward through the fine hole 121 to throw the glue out and onto the upper side plate 80, thereby achieving the coating of glue.

[0034] Below the cover 11 is a collection box 14 for collecting glue. Glue that is not applied to the upper side panel 80 or drips will fall onto the cover 11 and flow through the cover 11 into the collection box 14 for collection, thereby achieving the application of glue to the upper side panel 80. Furthermore, the cover 11's shielding effect during glue application can reduce glue spillage and collect the glue.

[0035] like Figure 3 As shown, in a preferred embodiment of the above, the cover 11 includes a first sealing portion 111, a second sealing portion 112, and a third sealing portion 113. The second sealing portion 112 protrudes downward, and the spraying cylinder 12 is located inside the second sealing portion 112. The bottom of the second sealing portion 112 is provided with a discharge port 114 for discharging glue, and a flexible hose connected to the discharge port 114 and connected to the collection box 14 is provided. The second sealing portion 112 and the third sealing portion 113 are transitioned by an inclined surface. The inclined surface facilitates the flow of glue into the second sealing portion 112 for collection. On the other hand, it increases the internal space of the cover 11, allowing the spraying cylinder 12 to throw the glue further when applying glue, resulting in a better glue application effect.

[0036] like Figure 3 , 5As shown in Figure 7, in a preferred embodiment, a baffle plate 15 is rotatably provided inside the spraying cylinder 12, partially surrounding the injection pipe 13. The baffle plate 15 is specifically in the shape of a "C" or "L". A sealing strip 16 is provided between the two sides of the baffle plate 15 and the inner wall of the spraying cylinder 12. The sealing strip 16 is made of rubber material and mainly scrapes the glue in the inner cavity of the spraying cylinder 12 to ensure that the glue is located in the concave surface of the baffle plate 15. When applying glue, the glue is introduced into the inner cavity of the spraying cylinder 12 through the injection pipe 13. The glue introduced by the injection pipe 13 is to make the glue in the spraying cylinder 12 more evenly distributed, and the glue application will be more uniform. The glue falling on the injection pipe 13 is collected in the concave surface of the baffle plate 15. When the spraying cylinder 12 rotates, the inner wall of the spraying cylinder 12 drives the glue to move and is thrown out through the fine hole 121 during rotation.

[0037] like Figure 5 , 7 As shown, the rotating shaft of the baffle plate 15 and the rotating shaft of the spraying cylinder 12 are rotatably sleeved together. The injection pipe 13 is inserted into the baffle plate 15 and fixed to it. The end of the injection pipe 13 and the end of the baffle plate 15 are connected by threads. A fixing member 151 is rotatably mounted on the rotating shaft of the baffle plate 15 to fix the baffle plate 15 and the cover 11 to each other. The fixing member 151 is specifically a threaded sleeve. The threaded sleeve and the support seat of the cover 11 are threaded together. A boss is provided on the rotating shaft of the baffle plate 15. After the fixing member 151 and the support seat of the cover 11 are fixed to each other, the boss is fixed to the support seat of the cover 11 to fix the baffle plate 15 to the cover 11. The blocking plate 15 is pressed against the support base to fix it. A handle 152 is also fixed on the rotating shaft of the blocking plate 15 to rotate the blocking plate 15 and adjust its position. The concave position of the blocking plate 15 can be rotated by the handle 152. When applying glue, the handle 152 can be adjusted so that the concave surface of the blocking plate 15 faces upward. When the glue application is stopped, the handle 152 can be adjusted so that the concave surface of the blocking plate 15 faces downward, so that the glue stored on the blocking plate 15 falls out. During the rotation of the spraying cylinder 12, the sealing strip 16 can scrape the glue residue on the inner wall of the spraying cylinder 12 clean, so as to prevent it from sticking and clogging on the spraying cylinder 12.

[0038] like Figure 1 , 4As shown in Figure 6, in a preferred embodiment, a plurality of vertical rods 17 are provided above the movable frame assembly 10 and the cover 11. A plurality of support wheels 18 are rotatably provided on the vertical rods 17 to support the upper side plate 80. Support pads 181 that contact the upper side plate 80 are provided at the edges of the support wheels 18. The support pads 181 are annularly sleeved on the outer edge of the support wheels 18, and the edges of the support pads 181 are W-shaped, which can provide more support for the upper side plate 80, but will not stick to the glue and will not affect the adhesive effect on the upper side plate 80.

[0039] like Figure 1 As shown, in a preferred embodiment of the above, a support roller group 19 for supporting the upper side plate 80 is fixedly arranged between the two vertical rods 17. The support roller group 19 is located above the upper side plate 80 and corresponds to the position of the cover 11. Specifically, the structure of the support roller group 19 includes several support rollers. The support rollers are in contact with the upper side surface of the upper side plate 80. A support frame is arranged between the several support rollers. The frame is fixed to the two vertical rods 17 by connecting rods. The main purpose of setting up the support roller group 19 is to prevent the upper side plate 80 from fluctuating up and down during glue application, which would result in poor glue application effect.

[0040] like Figure 1 , 2 As shown, in a preferred embodiment of the above, the movable frame assembly 10 includes a movable seat 101. A guide rail assembly 102 is movably disposed below the movable seat 101. The guide rail assembly 102 is fixedly disposed with respect to the frame of the transport lower side plate 81. Specifically, the guide rail assembly 102 includes a cylindrical guide rod disposed on the frame and a movable guide rail disposed on the frame. A connecting seat is fixedly disposed on the movable seat 101. The connecting seat and the cylindrical guide rod are slidably sleeved together. Rollers that can roll on the movable guide rail are disposed on the movable seat 101. A motor that drives the movable seat 101 to move is disposed on the frame. The motor drives the movement by means of a threaded screw. The direction is a horizontal linear movement along the front and rear direction of the guide rail assembly 102; a lifting seat 103 is provided above the movable seat 101, and several connecting rods are hinged between the lifting seat 103 and the movable seat 101. In this embodiment, two connecting rods are provided to form a parallelogram structure. A first electric push rod is provided between the movable seat 101 and one of the connecting rods to drive the movement of the connecting rod. The electric push rod mainly drives the lifting seat 103 to move up and down in the vertical direction. The top of the lifting seat 103 and the cover 11 are rotatably arranged relative to each other. A second electric push rod is provided between the lifting seat 103 and the cover 11 to drive the cover 11 to rotate and adjust the angle position of the cover 11.

[0041] The specific working principle of this invention is as follows: When applying glue, the glue is first introduced into the spraying cylinder 12 through the injection tube 13 and collected on the blocking plate 15. Then, the motor connected to the spraying cylinder 12 is started by controlling the motor to drive the spraying cylinder 12 to rotate. The spraying cylinder 12 will cause the glue to be thrown from the fine hole 121 onto the upper side plate 80. Some of the glue that is thrown out or drips is collected on the cover 11. Then, the glue is introduced into the collection box 14 through the discharge port 114 for collection and storage.

[0042] During adhesive application, the blocking plate 15 is adjusted via the handle 152 so that its concave side faces upward. After adhesive application is stopped, the motor connected to the spraying cylinder 12 is stopped, and the spraying cylinder 12 stops rotating. By rotating the handle 152, the concave side of the blocking plate 15 is positioned downward, and the adhesive on the blocking plate 15 falls through the fine hole 121 into the sealing cover 11. Furthermore, by adjusting the position of the handle 152, the blocking plate 15 can move within the spraying cylinder 12, thereby causing the sealing strip 16 to scrape the adhesive inside the spraying cylinder 12 clean and discharge it through the fine hole 121, reducing adhesion and clogging.

[0043] After the adhesive is applied, the arrangement angle of the cover 11 and the height of the lifting seat 103 can be adjusted by controlling the first electric push rod and the second electric push rod, so that the position of the cover 11 is lowered. Then, the motor connected to the movable seat 101 is started by controlling the movable seat 101 to move forward, so that it extends out from under the upper side plate 80, which is convenient for cleaning the cover 11 or the inside of the spraying cylinder 12.
