Description

TECHNICAL FIELD

[0001] The present application relates to a wood product mortise and tenon joint device, in particular to a wood product mortise glue dripping equipment. BACKGROUND

[0002] At present, many solid wood products and panel furniture adopt mortise and tenon joint process, which needs to drip glue in the mortise first, then insert the tenon into the mortise, and realize firm mortise and tenon joint after the glue solidifies. In the existing mortise and tenon joint process, viscous glue such as milk white glue is often used, in order to prevent the glue from flowing out or spilling out during processing, the tenon needs to be inserted into the mortise for mortise and tenon joint immediately after the glue is dripped in the mortise, which has the following problems: ① The mortise glue dripping and the tenon insertion into the mortise must be integrated in the same machine as much as possible, which makes the machine structure complex and the price high; ② The two steps of mortise glue dripping and tenon insertion into the mortise cannot be separated, which limits the flexibility of production line arrangement and thus limits the improvement of production capacity. SUMMARY

[0003] In order to solve the above problems, the present application discloses a wood product mortise glue dripping equipment with a sealing function after glue dripping, which seals the mortise after glue dripping to prevent the glue in the mortise from flowing out in advance.

[0004] In order to achieve the above purpose, the present application adopts the following technical scheme.

[0005] A wood product mortise glue dripping equipment with a sealing function after glue dripping, comprising a base, an X-axis guide rail, a Y-axis guide rail, a workbench, a glue dripping device and the like, characterized in that it further comprises a mortise sealing device, the mortise sealing device comprises a pneumatic cylinder, a piston rod, a sliding block, a sealing belt, a sealing belt support and a sealing head, the sealing belt support and the sealing head are fixed on the sliding block, the sealing belt is installed on the sealing belt support, one end of the sealing belt is connected to the sealing head, after the glue dripping device drips glue in the wood product mortise, the sealing device moves to the top of the mortise through the X-axis guide rail and the Y-axis guide rail, the pneumatic cylinder drives the piston rod and the sliding block to descend, so that the sealing head fixed on the sliding block presses the sealing belt on the mortise to realize sealing. The beneficial effects of the structure are that: after the glue dripping device drips glue in the mortise, the sealing device seals the mortise with the sealing belt to prevent the glue from flowing out during processing, so that the two steps of mortise glue dripping and tenon insertion into the mortise can be carried out separately, which is convenient for flexible adjustment of the production line and is conducive to the improvement of production capacity.

[0006] Further, the sealing head comprises an upper feeding roller, a lower feeding roller, a pressing plate, an upper discharging roller and a lower discharging roller. Before each pressing, the upper feeding roller and the lower feeding roller rotate in an axis-symmetrical and reverse direction to feed the sealing tape segment to be used to the working position of the pressing plate, while the upper discharging roller and the lower discharging roller rotate in an axis-symmetrical and reverse direction to pull out the used sealing tape segment after the last pressing to the working position of the pressing plate. When the sealing tape segment to be used is fed to the working position of the pressing plate, the cylinder drives the piston rod and the slider to descend, so that the sealing head fixed on the slider presses the sealing tape on the mortise hole. Then, the cylinder drives the piston rod, the slider and the sealing head fixed on the slider to lift up, and the mortise hole sealing is completed.

[0007] Further, the surface of the lower feeding roller in the sealing head is covered with a layer of polytetrafluoroethylene. The structure has the beneficial effect of ensuring the smooth surface of the lower feeding roller, thereby avoiding the adhesion of the tape layer on the roller during feeding.

[0008] Further, the sealing tape has a two-layer structure, which is composed of a base tape layer and a tape layer. The base tape layer is double-sided release paper. The tape layer is light, thin, low in toughness and low in initial adhesion, and the adhesion increases after pressing. The structure has the beneficial effect that the initial adhesion of the tape layer is low when the feeding roller in the sealing head feeds the sealing tape, so that the tape layer will not adhere to the roller. After pressing by the sealing head, the adhesion of the tape layer increases, so that the tape layer is not easy to fall off from the sealed mortise hole in the subsequent processing after glue dropping and sealing. The tape layer is light, thin and low in toughness, so that when the tenon is inserted into the mortise, the tenon can easily pierce the sealing tape and enter the mortise, without affecting the mortise joint.

[0009] Further, the tape layer of the sealing tape has a pre-cut structure, i.e. the tape layer is pre-cut every length L, and the length of each tape layer is L. The structure has the beneficial effect that each time the sealing head is pressed, a tape layer is pressed and attached to the mortise to be sealed, and is peeled off from the base tape layer, without the need for additional installation of a tape cutting device. The base tape layer does not need to be cut during processing, which ensures the continuity of the sealing tape from the feeding roller to the discharging roller, and improves the processing efficiency.

[0010] Further, the width of the sealing tape is B, which satisfies the relationship 1.5d

[0011] Further, the sealing tape support comprises a base, a rotating shaft and a rotating wheel, the sealing tape is wound on the rotating wheel, before the upper feeding roller and the lower feeding roller rotate to feed the sealing tape each time, the rotating shaft of the sealing tape support rotates to make the sealing tape wound on the rotating wheel release the length of sealing tape required for this time sealing. The structure has the advantages that the sealing tape is released in advance by the active rotation of the rotating wheel, the working load of the feeding roller is reduced, the pressing force between the upper feeding roller and the lower feeding roller is reduced, and the excessive pressure applied to the adhesive tape layer in advance is avoided to be adhered to the lower feeding roller.

[0012] Further, the upper feeding roller, the lower feeding roller, the upper discharging roller and the lower discharging roller are driven by a stepping motor. The structure has the advantages that the feeding length of the sealing tape is the same each time, and the stepping angle of the upper feeding roller, the lower feeding roller, the upper discharging roller and the lower discharging roller is the same each time.

[0013] Further, the rotating shaft of the sealing tape support is driven by a stepping motor. The structure has the advantages that the sealing tape is wound and installed on the rotating wheel of the sealing tape support, the rotating wheel releases the sealing tape with the same length each time, the stepping angle required by the rotating shaft gradually increases, and the precise control of the rotation of the rotating shaft is realized.

[0014] In conclusion, the wood product mortise glue dropping equipment has the advantages that after the glue is dropped in the mortise, the sealing device seals the mortise by the sealing tape to prevent the glue from flowing out in the processing process, so that the two steps of the glue dropping in the mortise and the tenon insertion into the mortise can be carried out separately, the complexity of the machine is reduced, and the production cost and the maintenance cost are reduced; the production line is flexible to adjust, and the production capacity is improved.

DETAILED DESCRIPTION

[0022] The technical solutions in the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0023] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 , a wood product mortise hole glue dropping equipment with a glue dropping sealing function comprises a frame 1, a workbench 2, an X-axis guide rail 5, a Y-axis guide rail 6, a glue dropping device 7 and the like, characterized in that it further comprises a mortise hole sealing device 4, the mortise hole sealing device 4 comprises an air cylinder 8, a piston rod 9, a sliding block 10, a sealing tape 14, a sealing tape support 11 and a sealing head 15, the sealing tape support 11 and the sealing head 15 are fixed on the sliding block 10, the sealing tape 14 is installed on the sealing tape support 11, one end of the sealing tape 14 is connected to the sealing head 15, after the glue dropping device 7 drops glue in the mortise hole 3 of the wood product, the sealing device 4 is moved above the mortise hole 3 through the X-axis guide rail 5 and the Y-axis guide rail 6, the air cylinder 8 drives the piston rod 9 and the sliding block 10 to descend, so that the sealing head 15 fixed on the sliding block 10 presses the sealing tape 14 on the mortise hole 3 to realize sealing. The beneficial effects of the structure are that after the glue dropping device 7 drops glue in the mortise hole 3, the sealing device 4 seals the mortise hole 3 by using the sealing tape 14, preventing glue from flowing out in the processing process, so that the two steps of mortise hole glue dropping and tenon insertion into the mortise hole can be carried out separately, facilitating flexible adjustment of the production line and being conducive to improvement of production capacity.

[0024] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the drawings, the sealing head 15 comprises an upper feeding roller 17, a lower feeding roller 16, a pressing plate 18, an upper discharging roller 19 and a lower discharging roller 20. Before each pressing, the upper feeding roller 17 and the lower feeding roller 16 rotate in opposite directions to feed the sealing tape segment to be used to the working position of the pressing plate 18, while the upper discharging roller 19 and the lower discharging roller 20 rotate in opposite directions to pull the used sealing tape segment out of the working position of the pressing plate 18. When the sealing tape segment to be used is fed to the working position of the pressing plate 18, the cylinder 8 drives the piston rod 9 and the sliding block 10 to descend, so that the sealing head 15 fixed on the sliding block 10 presses the sealing tape 14 on the mortise hole 3, and then the cylinder 8 drives the piston rod 9, the sliding block 10 and the sealing head 15 fixed on the sliding block 10 to ascend, thus completing the sealing of the mortise hole.

[0025] As shown in the drawings, Figure 2 , Figure 3 and Figure 4 , the surface of the lower feeding roller 16 in the sealing head 15 is covered with a layer of polytetrafluoroethylene. The beneficial effect of this structure is that the surface of the lower feeding roller 16 is smooth, so that the adhesive tape layer 21 is not adhered to the roller during feeding.

[0026] As shown in the drawings, Figure 5 and Figure 6 , the sealing tape 14 has a two-layer structure, which is composed of a base tape layer 22 and an adhesive tape layer 21. The base tape layer 22 is double-sided release paper, and the adhesive tape layer 21 is light and thin, has low toughness and low initial adhesion, and has increased adhesion after being pressed. The beneficial effect of this structure is that the adhesive tape layer 21 has low initial adhesion and thus is not adhered to the roller during feeding of the sealing tape 14 by the feeding roller in the sealing head 15; the adhesive tape layer 21 has increased adhesion after being pressed by the sealing head 15, so that the adhesive tape layer 21 is not easily detached from the sealed mortise hole 3 in the subsequent processing after glue dropping and sealing; the adhesive tape layer 21 is light and thin and has low toughness, so that the pin can easily pierce the adhesive tape layer 21 and enter the mortise hole 3 when the pin is inserted into the mortise hole 3, without affecting the mortise joint.

[0027] As shown in the drawings, Figure 5 and Figure 6 , the adhesive tape layer 21 of the sealing tape 14 has a pre-cut structure, i.e. the adhesive tape layer 21 is pre-cut every length L, and each segment of the adhesive tape layer has a length of L. The beneficial effect of this structure is that one segment of the adhesive tape layer 21 is pressed and attached to the mortise hole 3 to be sealed and is peeled off from the base tape layer 22 during each pressing of the sealing head 15, so that a separate adhesive tape cutting device is not needed; the base tape layer 22 does not need to be cut during processing, which ensures the continuity of the sealing tape 14 from the feeding roller to the discharging roller and improves the processing efficiency.

[0028] As shown in the drawings, Figure 6As shown in the drawings, the sealing tape 14 has a width B, and B satisfies the relationship: 1.5d<B<2d, and the length L of the single tape layer satisfies the relationship: 2d<L<3d, wherein d is the diameter of the dowel hole 3. The structure has the beneficial effect that the sealing tape width B and the single tape layer length L are not too small to avoid the small bonding area causing the tape layer 21 on the dowel hole 3 to fall off, and the sealing tape width B and the single tape layer length L are not too large to ensure the beauty of the dowel joint of the wooden product.

[0029] As shown in the drawings, Figure 2 , Figure 3 and Figure 4 , the sealing tape holder 11 includes a base, a rotating shaft 12 and a rotating wheel 13, and the sealing tape 14 is wound on the rotating wheel 13. Before the upper feeding roller 17 and the lower feeding roller 16 rotate to feed the sealing tape 14 each time, the rotating shaft 12 of the sealing tape holder 11 drives the rotating wheel 13 to rotate, so that the sealing tape 14 wound on the rotating wheel 13 is released for the length required for this time sealing. The structure has the beneficial effect that the sealing tape 14 is actively released in advance by the rotating wheel 13, which reduces the working load of the feeding roller, thereby reducing the pressing force between the upper feeding roller 17 and the lower feeding roller 16, and avoiding the excessive pressure applied to the tape layer 21 in advance to adhere to the lower feeding roller 16.

[0030] As shown in the drawings, Figure 4 , the upper feeding roller 17, the lower feeding roller 16, the upper discharge roller 19 and the lower discharge roller 20 are driven by a stepping motor. The structure has the beneficial effect that the feeding length of the sealing tape is the same each time, so that the stepping angle of the upper feeding roller 17, the lower feeding roller 16, the upper discharge roller 19 and the lower discharge roller 20 is the same each time.

[0031] As shown in the drawings, Figure 2 , Figure 3 , the rotating shaft 12 of the sealing tape holder 11 is driven by a stepping motor. The structure has the beneficial effect that the sealing tape 14 is wound and installed on the rotating wheel 13 of the sealing tape holder 11, the same length of the sealing tape is released each time the rotating wheel 13 rotates, and the stepping angle required by the rotating shaft 12 gradually increases to achieve precise control of the rotation of the rotating shaft 12.

[0032] The beneficial effect of the present application is that after the glue dropping device drops glue in the dowel hole, the sealing device seals the dowel hole with the sealing tape to prevent the glue from flowing out during processing, so that the two steps of dowel hole glue dropping and dowel insertion into the dowel hole can be performed separately, which reduces the complexity of the machine, reduces the production cost and maintenance cost, and facilitates the flexible adjustment of the production line, which is conducive to the improvement of production capacity.
