Description

Technical Field

[0001] This utility model relates to the field of glue coating machine technology, specifically a glue coating machine for marine board production and processing. Background Technology

[0002] Marine board is a type of engineered wood product made from wood or plant fibers. The fibers are broken down, separated, dried, and then bonded together with adhesives before being hot-pressed. It features uniform material, stable structure, and strong nail-holding power, and is commonly used in furniture manufacturing and interior decoration. It also boasts good environmental performance, meeting certain environmental requirements, making it a relatively common type of building material in the decoration industry.

[0003] In the production of marine panels, adhesive is applied to the surface of the panels using a coating machine. Existing technology uses a guide rail to drive a coating head in a reciprocating motion to apply the adhesive. The stroke of this motion is adjusted to accommodate panels of different widths. However, to ensure uniform coating, high precision is required for the guide rail movement. Furthermore, the pause when the coating head reaches the edge and then moves back can lead to excessive adhesive application at the panel edges. Therefore, we propose a coating machine for marine panel production. Utility Model Content

[0004] The purpose of this invention is to provide a glue-applying machine for marine board production and processing. By rotatably mounting the glue-applying head on the lower side of the crossbeam, when boards of different widths are placed on the conveyor belt for glue application, the glue-applying head can be rotated to different angles according to the width of the board, ensuring that the glue outlet tube at the bottom of the glue-applying head is located on the upper surface of the board. Since the conveyor belt has a fixed conveying speed, the glue can be evenly applied to the surface of the board and excessive glue can be avoided on the edges of the board, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glue-applying machine for marine board production and processing, comprising an outer frame, a conveyor belt, and a crossbar. The conveyor belt is rotatably installed on the inner side of the outer frame. The crossbar is longitudinally supported on the side of the outer frame above the conveyor belt. A sleeve is welded and fixed at the middle position of the side of the crossbar, and a longitudinal glue-applying head is provided below the sleeve. A glue inlet pipe communicating with the interior is vertically connected at the middle position above the glue-applying head. The glue inlet pipe rotatably passes through the sleeve, and a support block supporting the upper part of the sleeve is fixed on the outer ring of the glue inlet pipe. A locking bolt with its end abutting against the outer surface of the glue inlet pipe is screwed onto the outer surface of the sleeve by a screw connection. Multiple glue outlet pipes communicating with the interior are equidistantly arranged at the bottom of the glue-applying head.

[0006] By adopting the above technical solution, the spacing of the positioning plates can be adjusted according to the width of the sheet to be glued, and the rotation angle of the glue spraying head can be adjusted and locked according to the width of the sheet, so as to ensure that the glue can be evenly sprayed onto the surface of the sheet below, and to avoid the situation where too much glue is applied to the edge position.

[0007] Optionally, a first plastic strip, a second plastic strip, and a third plastic strip of the same length are also provided, and the sides of the first plastic strip, the second plastic strip, and the third plastic strip are all connected and fixed with rubber sleeves that can be fitted and sealed to the outer ring of the dispensing tube.

[0008] By adopting the above technical solution, when the board is relatively narrow and the rotation angle of the glue spraying head is too large, resulting in a relatively small spacing in the longitudinal direction of the glue dispensing tube, the rubber sleeves on the sides of the first, second, or third plastic strips can be used to block part of the glue dispensing tube, thereby avoiding excessive glue density in the longitudinal direction.

[0009] Optionally, when the rubber sleeve on the side of the first plastic strip is fitted to seal the outer ring of the dispensing tube, the spacing between the unsealed dispensing tubes is equal to twice the spacing between adjacent dispensing tubes.

[0010] By adopting the above technical solution, the number of dispensing pipes blocked is minimized, and the reduction in glue density in the longitudinal direction of the dispensing pipe is minimized.

[0011] Optionally, when the rubber sleeve on the side of the second plastic strip is fitted to seal the outer ring of the dispensing tube, the spacing between the unsealed dispensing tubes is equal to three times the spacing between adjacent dispensing tubes.

[0012] By adopting the above technical solution, the number of glue outlet tubes blocked is moderate, and the glue density of the glue outlet tubes in the longitudinal direction is reduced moderately.

[0013] Optionally, when the rubber sleeve on the side of the third plastic strip is fitted to seal the outer ring of the dispensing tube, the spacing between the unsealed dispensing tubes is equal to four times the spacing between adjacent dispensing tubes.

[0014] By adopting the above technical solution, the number of dispensing pipes that can be blocked is the largest, and the glue density of the dispensing pipes in the longitudinal direction is reduced the most.

[0015] Optionally, the front and rear end outer frame surfaces of the cross frame are fixed with parallel side plates, and the conveyor belt surface on the side of the side plate is provided with a positioning plate parallel to the side plate. Both sides of the positioning plate are fixed with screws that can slide through to the other side of the side plate, and the outer rings of the screws on both sides of the side plate are screwed with nuts that abut against the surface of the side plate.

[0016] By adopting the above technical solution, the plate material is centered and transported using a positioning plate with adjustable spacing.

[0017] Optionally, the inner surface of the positioning plate is rotatably mounted with guide wheels, and multiple guide wheels are provided.

[0018] By adopting the above technical solution, the side edge of the plate can be kept away from the positioning plate, thus avoiding an increase in transmission resistance.

[0019] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0020] 1. The technical solution of this application allows the glue-applying head to be rotatably installed on the lower side of the crossbeam. When boards of different widths are placed on the surface of the conveyor belt for glue application, the glue-applying head can be rotated to different angles according to the width of the board, ensuring that the glue outlet tube at the bottom of the glue-applying head is located on the upper surface of the board. Since the conveyor belt has a fixed conveying speed, the glue can be evenly applied to the surface of the board and excessive glue can be avoided on the edges of the board.

[0021] 2. The technical solution of this application also includes a first plastic strip, a second plastic strip, and a third plastic strip with rubber sleeves. When the angle of rotation of the glue dispensing head is too large, the corresponding first plastic strip, second plastic strip, or third plastic strip can be selected according to its angle. The rubber sleeves on the sides can be used to block the corresponding number of glue dispensing tubes, thereby avoiding excessive glue dispensing density in the longitudinal direction and resulting in glue waste.

[0029] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a glue-coating machine for marine board production and processing, including an outer frame 1, a conveyor belt 2 and a crossbeam 3. The conveyor belt 2 is rotatably installed on the inner side of the outer frame 1. Support legs are provided on both sides of the front and rear ends of the outer frame 1 to support the entire frame. A motor connected to the guide roller is installed on the surface of the outer frame 1 at the front end of one end of the conveyor belt 2. After the motor is connected to the industrial control computer, it can control the conveyor belt 2 to rotate at different speeds as required. When the conveyor belt 2 rotates counterclockwise, it can transport the board to the left.

[0030] During transmission, the sheet material needs to move to the left in a centered position. To achieve this, parallel side plates 5 are fixed to the front and rear outer frames 1 on the sides of the cross frame 3. Positioning plates 6 parallel to the side plates 5 are provided on the surface of the conveyor belt 2 on the side of the side plates 5. Screws 61 that can slide through to the other side of the side plates 5 are fixed to both sides of the surface of the positioning plates 6. Nuts 611 that abut against the surface of the side plates 5 are screwed onto the outer ring of the screws 61 on both sides of the side plates 5. After loosening the nuts 611 on the screws 61, the distance between the two positioning plates 6 can be adjusted so that the distance between the positioning plates 6 is adapted to the width of the sheet material to be glued and ensures that the sheet material can be positioned in the middle of the surface of the conveyor belt 2. Then, the nuts 611 are tightened to abut against the two sides of the side plates 5, thereby locking the position of the positioning plates 6. Guide wheels 62 are rotatably installed on the inner surface of the positioning plates 6. Multiple guide wheels 62 are provided. When the sheet material is placed between the two positioning plates 6 and transmitted to the left, the side of the sheet material contacts the guide wheels 62 to avoid the side of the sheet material from being released from the positioning plates 6 and causing significant resistance.

[0031] The aforementioned crossbeam 3 is longitudinally supported on the side of the outer frame 1 above the conveyor belt 2, and a sleeve 31 is welded and fixed at the middle position of the side of the crossbeam 3. A longitudinal glue-applying head 4 is provided below the sleeve 31. Multiple glue-dispensing pipes 42 communicating with the interior are equidistantly arranged at the bottom of the glue-applying head 4. A glue-inlet pipe 41 communicating with the interior is vertically connected at the middle position above the glue-applying head 4. The glue-inlet pipe 41 rotatably passes through the sleeve 31, and a support block 411 is fixed on the outer ring of the glue-inlet pipe 41 above the sleeve 31, supporting the upper part of the sleeve 31. The support block 411 serves to support the glue-inlet pipe 41 and the glue-applying head 4. The glue-inlet pipe 41 can rotate within the sleeve 31 to adjust the glue-applying head. The angle of the glue applicator 4 is 4, so when using it, the angle of the glue applicator 4 can be adjusted according to the width of the board. All the glue outlet tubes 42 at the bottom of the glue applicator 4 are always above the board, and the outermost glue outlet tube 42 is above the edge of the board. After the glue inlet tube 41 is connected to the glue supply tube, when the board is driven to the left and passes under the glue applicator 4, the glue enters the glue applicator 4 and is evenly sprayed down from the through hole of the glue outlet tube 42 onto the surface of the board. This can avoid the situation of excessive glue spraying at the edge. In order to achieve the purpose of continuous glue spraying, the board can be placed in close contact with the surface of the conveyor belt 2 and is transported to the left.

[0032] A locking bolt 311 is screwed onto the outer surface of the sleeve 31 by means of a screw connection. The end of the locking bolt 311 extends through the inner side of the sleeve 31. When the glue dispensing head 4 is adjusted into place, the locking bolt 311 is tightened so that its end abuts against the outer surface of the glue inlet tube 41, thereby locking the angle of the glue dispensing head 4.

[0033] When the board material is relatively narrow, excessive rotation angle of the glue applicator 4 may cause excessive glue density in the longitudinal direction. To resolve this issue, please refer to [link to relevant documentation]. Figures 3 to 5 It is also provided with a first plastic strip 43, a second plastic strip 44 and a third plastic strip 45 of the same length. The sides of the first plastic strip 43, the second plastic strip 44 and the third plastic strip 45 are all connected and fixed with rubber sleeves 46 that can be fitted and sealed on the outer ring of the dispensing tube 42.

[0034] When the rubber sleeve 46 on the side of the first plastic strip 43 is fitted and sealed on the outer ring of the glue outlet tube 42, the spacing between the unsealed glue outlet tubes 42 is equal to twice the spacing between adjacent glue outlet tubes 42. This allows the glue spraying head 4 to be tilted and its glue spraying density in the longitudinal direction to be reduced to half of the original density, which is suitable for the glue spraying needs of the widest board among the narrowest boards.

[0035] When the rubber sleeve 46 on the side of the second plastic strip 44 is fitted and sealed on the outer ring of the glue outlet tube 42, the spacing between the unsealed glue outlet tubes 42 is equal to three times the spacing between adjacent glue outlet tubes 42. This allows the glue spraying head 4 to be tilted and its glue spraying density in the longitudinal direction to be reduced to one-third of the original, which is suitable for glue spraying needs of moderately wide boards in narrow boards.

[0036] When the rubber sleeve 46 on the side of the third plastic strip 45 is placed and sealed on the outer ring of the dispensing tube 42, the spacing between the unsealed dispensing tubes 42 is equal to four times the spacing between adjacent dispensing tubes 42. This allows the dispensing head 4 to be tilted so that its dispensing density in the longitudinal direction is reduced to one-quarter of the original density, which is suitable for dispensing the narrowest board among narrower boards.

[0037] It should also be noted that after adjusting the glue application density as described above, the movement speed of the conveyor belt 2 can also be controlled to more accurately apply the appropriate amount of glue to the surface of the board.

[0038] In use, turn all the nuts 611 on the screws 61 away from the side plate 5 to adjust the distance between the two positioning plates 6, so that the distance between the positioning plates 6 is adapted to the width of the board to be glued, and ensures that the board can be positioned in the middle of the surface of the conveyor belt 2. Then turn the nuts 611 to make them abut against the two sides of the side plate 5, thereby locking the position of the positioning plates 6. Then loosen the locking bolt 311 to release the lock on the glue inlet pipe 41, so that the feed pipe can rotate in the sleeve 31 to adjust the angle of the lower glue head 4, ensuring that when the board is placed under the crossbar 3, all the glue outlet pipes 42 at the bottom of the glue head 4 are above the board, and the glue outlet pipes 42 at the edge are above the edge of the board. Then, tighten the locking bolt 311 so that its end presses against the outer surface of the glue inlet pipe 41 to lock it so that it cannot rotate with the glue spray head 4. Then connect the glue inlet pipe 41 to the glue supply pipe. The control end of the motor of the conveyor belt 2 is connected to the industrial control computer, which drives the conveyor belt 2 to rotate counterclockwise at a constant speed. Place the board tightly against the right side of the conveyor belt 2. The board is transported to the left by the conveyor belt 2. It is supported and guided by the guide wheel 62 between the two positioning plates 6 and transported to the left in the center. When the board is transported to the position below the spray head, the valve on the glue supply pipe is opened, so that the pressurized glue enters the glue spray head 4 through the glue inlet pipe 41 and flows out from the through hole of the glue outlet pipe 42, which can be evenly sprayed onto the upper surface of the board. When the glue applicator 4 rotates to a large angle due to the board passing through the gate, in order to avoid the glue being applied too densely to the board surface and causing waste, a first plastic strip 43, a second plastic strip 44, or a third plastic strip 45 can be used to block different numbers of glue outlet tubes 42 before applying the glue, depending on the width of the board. That is, the narrower the board, the more glue outlet tubes 42 are blocked, and vice versa. The rubber sleeves 46 on the side of the third plastic strip 45, the second plastic strip 44, or the first plastic strip 43 are used to block the corresponding number of glue outlet tubes 42. In conjunction with controlling the speed of the conveyor belt 2 in conveying the board, the amount of glue applied to the board surface can be reasonably controlled.
