Description

Technical Field

[0001] The invention relates to the technical field of decorative panel processing, in particular to a decorative panel pressing and post-lamination drying device. Background Art

[0002] Veneer is a decorative veneer plywood. It is a surface material used for interior decoration or furniture manufacturing. It is made by slicing natural wood or technical wood into thin slices of a certain thickness, adhering them to the surface of plywood, and then hot pressing. Common veneers are divided into natural wood veneer veneers and artificial veneer veneers. The difference in appearance between artificial veneer and natural wood veneer is that the texture of the former is basically straight or has a regular pattern, while the latter has a natural wood pattern, with a natural texture pattern, large variability and no regularity. Its characteristics are that it has both the beautiful patterns of wood and makes full use of wood resources to reduce costs.

[0003] Most of the current pressing equipment only applies pressure to the veneer and plywood to make the two stick together. Due to the lack of drying of the veneer and plywood, the glue between the two needs to stand for a long time to be completely adhered, which affects the pressing efficiency. The simple use of heating tubes or heating plates cannot meet the needs of rapid drying of large areas of veneer. In the early stage of pressing, the pressing of veneer and plywood is limited by the shape of the press. The areas contacted and squeezed by the press are pressed tightly, while there are gaps and air bubbles in the uncontacted areas. There is the problem of bubbles. Bubbles are generated in the gaps between the veneer and the plywood, and in the internal glue. If they are dried directly without being treated, the bonding effect of the veneer and the plywood will be affected. At the same time, after the veneer and the plywood are pressed, the glue will be squeezed out from the board surface due to the pressing force, and a small amount of glue will drip around the veneer or the plywood. After the glue is dried, it will cause the veneer and the plywood to stick to the pressing machine. In the later stage, it is also necessary to scrape out the glue that has seeped out and dried. In view of this, we propose a device for drying veneer after pressing. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 12 As shown, the technical solution provided by the present invention is:

[0037] A device for drying a decorative panel after pressing and laminating, comprising a pressing base 1, wherein a drying heat-conducting plate 2 is slidably connected inside the pressing base 1, wherein the drying heat-conducting plate 2 can be made of a metal sheet or a metal mesh plate, wherein the diameter of the hole on the mesh plate needs to be smaller than the diameter of the ball on the vibrating ball rod 854 mentioned below, and the hole on the mesh plate needs to be staggered with the ball to avoid the vibrating ball rod 854 from interfering with the mesh groove inside the mesh plate when colliding, wherein a heating tube 3 is fixedly connected inside the pressing base 1; a motor 4 is mounted on the surface of the pressing base 1, wherein a bent rod 5 is clamped on the output shaft of the motor 4, wherein the end of the bent rod 5 is slidably connected to a limit frame 6, wherein a gas pressure push plate 7 is fixedly connected to the limit frame 6; and a heating tube 3 is fixedly connected inside the pressing base 1; wherein the ... the motor 4 is clamped on the output shaft of the motor 4, wherein the motor 4 is clamped on the output shaft of the motor 4, wherein the motor 4 is clamped on the output shaft of the motor 4, wherein the motor 4 is clamped on the output shaft of the motor 4, wherein the motor 4 is clamped on the output shaft of the motor 4, wherein the motor 4 is clamped on the output shaft of the motor 4, wherein the motor 4 is clamped on the output shaft of the motor 4, wherein the motor 4 is clamped on the output shaft of During the heating and drying process, the motor 4 drives the upper limit frame 6 of the curved rod 5 to drive the air pressure push plate 7 to reciprocate in the pressing base 1, so as to achieve the purpose of pushing the internal heating gas, and use the continuously circulating hot air flow to blow and dry the panel surface, thereby increasing the drying rate of the glue, and at the same time promoting the adhesion rate after pressing, thereby improving the drying effect. The rolling device 8 is arranged inside the pressing base 1, and is used to uniformly roll the decorative panel on the dried heat conduction plate 2 after bonding; the leaked glue processing device 9 is arranged inside the pressing base 1, and is used to clean the glue leaked around the decorative panel after bonding.

[0038] In this embodiment, the rolling device 8 includes a reciprocating screw 81, the end of the reciprocating screw 81 is rotatably connected to the inside of the pressing base 1, the surface of the reciprocating screw 81 is slidably connected to a sliding seat 82, and the sliding seat 82 is elastically connected to a rolling base 83 through a spring, and a telescopic guide rod is arranged between the sliding seat 82 and the rolling base 83, and the guide rod is used to connect the sliding seat 82 and the rolling base 83 to ensure that they can move coaxially and can perform telescopic work at the same time, and a rotating pressure roller 84 is rotatably connected to the rolling base 83, and a front and rear vibration device 85 is arranged inside the rolling base 83, and a linkage device 86 is arranged at the end of the reciprocating screw 81. In the early stage of pressing, the pressing of the veneer and the plywood is restricted by the shape of the press. The areas contacted and squeezed by the press are pressed tightly, while there are gaps and bubbles in the uncontacted areas. The rolling device 8 drives the rolling base 83 on the sliding seat 82 to drive the rotating pressing roller 84 to roll and squeeze the surface of the drying heat-conducting plate 2 through the rotation of the reciprocating screw 81, thereby achieving the effect of uniformly squeezing the surface of the drying heat-conducting plate 2, and uniformly rolling the surface of the drying heat-conducting plate 2, further achieving a comprehensive and uniform squeezing effect on the pressing area of ​​the veneer and the plywood, thereby achieving the effect of reducing the problem of gaps and bubbles, improving the connection effect of drying after pressing, and avoiding the problem of poor fixing effect of the veneer and plywood with gaps or bubbles after pressing and drying due to insufficient bonding.

[0039] Furthermore, the surface of the sliding seat 82 is slidably connected to the inside of the pressing base 1, and the front and rear vibration device 85 includes a rotating bin 851 and a vibrating gear rod 855. The teeth on the vibrating gear rod 855 have a large gap, which is used for intermittently meshing the vibrating gear 852, that is, when the vibrating gear 852 moves in a straight line, its upper teeth contact the teeth on the vibrating gear rod 855, and after meshing and rotating for a short range of angles, the teeth gradually lose the meshing effect with the teeth on the gear rod. When not meshing, the vibrating gear 852 is elastically rotated and reset, and the reset gear moves for a period of time and then meshes with the vibrating gear rod 855 again. After the meshing rotation, the meshing effect is lost again and the rotation is reset, and so on. When the vibrating gear 852 moves as a whole, it continuously meshes with the vibrating gear rod 855, and then loses meshing. The surface of the rotating bin 851 is elastically connected to the inside of the rolling base 83 through a torsion spring. The rotating bin 851 is elastically positioned by the setting of a torsion spring. When it is rotated by force, it can be rotated and reset according to the elastic force. One end of the rotating bin 851 passes through the interior of the roller base 83 and is fixedly connected to a vibration gear 852. The other end of the rotating bin 851 is elastically connected to a long rod 853 through a torsion spring. The long rod 853 is elastically positioned by the setting of the torsion spring. Under normal circumstances, the rotating bin 851 can drive the long rod 853 to rotate according to the elastic force. When the vibration ball bar 854 on the long rod 853 receives a large resistance, it can elastically give way, thereby avoiding the problem of damage caused by the vibration ball bar 854 hard hitting the drying heat conducting plate 2. At the same time, the purpose of impact vibration can be achieved. The surface of the long rod 853 is fixedly connected to the vibration ball bar 854, and the vibration gear 852 is made to rotate in both directions during movement through intermittent meshing, that is, forward rotation and reverse reset rotation. Figure 3 It can be seen that two groups of symmetrically distributed vibration ball bars 854 are arranged on the long rod 853. The forward and reverse rotating vibration gear 852 can drive the two groups of vibration ball bars 854 on the long rod 853 to hit the bottom of the drying heat conducting plate 2 in sequence through the rotating bin 851. The two groups of vibration ball bars 854 hit the bottom of the drying heat conducting plate 2 in sequence, which can achieve the effect of improving the vibration range and frequency of the drying heat conducting plate 2, thereby improving the vibration mixing of the adhesive inside the veneer and the plywood, and realizing the rapid removal of bubbles and gaps.

[0040] Furthermore, the surface of the rotating bin 851 is rotatably connected to the inside of the rolling base 83, the end of the long rod 853 is rotatably connected to the inside of the rotating bin 851, and a clearance groove 856 is provided inside the rotating bin 851. The surface of the vibrating gear rod 855 is slidably connected to the inner wall of the pressing base 1, and the vibrating gear rod 855 can slide linearly in the pressing base 1. The end of the long rod 853 is fixedly connected with a block 857, and the block 857 slides on the inner wall of the clearance groove 856. The block 857 and the clearance groove 856 limit the long rod 853 from rotating in the rotating bin 851 to limit its range of rotation and clearance, thereby avoiding the problem of excessive angle deviation between the long rod 853 and the rotating bin 851, and ensuring that the vibrating ball rod 854 is close to the drying heat conduction plate 2 for impact vibration.

[0041] It is worth noting that the linkage device 86 includes an active gear roller 861, which is fixed on the surface of the curved rod 5. The surface of the active gear roller 861 is connected to the auxiliary gear roller 863 through a connecting toothed belt 862. The surface of the connecting toothed belt 862 is meshed with a rotating gear 864. A crankshaft 865 is fixedly connected to the rotating gear 864. The end of the crankshaft 865 is slidably connected to a limit block 866. The connecting toothed belt 862 drives the upper limit block 866 of the crankshaft 865 to drive the vibrating gear rod 855 to move back and forth through the rotating gear 864. When moving, the vibrating gear rod 855 drives the vibrating gear 852 during the meshing period thereon to rotate. The vibrating gear 852 rotates forward and backward within the meshing range, thereby achieving the effect of increasing the rotation frequency of the vibrating gear 852. The vibrating gear 852 drives the impact frequency of the vibrating ball rod 854 on the long rod 853 through the rotating bin 851, thereby increasing the vibration mixing of the adhesive inside the veneer and the plywood, thereby achieving rapid removal of bubbles and gaps.

[0042] It is worth mentioning that the interior of the auxiliary gear roller 863 is fixedly connected to the end of the reciprocating screw 81, so that the reciprocating screw 81 on the auxiliary gear roller 863 is driven to rotate during the transmission of the toothed belt 862, and then the rotation of the reciprocating screw 81 is used to achieve the purpose of linear reciprocating movement of the sliding seat 82. The surface of the crankshaft 865 is rotationally connected to the inside of the pressing base 1, and the surface of the limit block 866 is slidingly connected to the inside of the pressing base 1. The surface of the limit block 866 is fixedly connected to the end of the vibration gear rod 855, and the movement of the limit block 866 is used to control the synchronous movement of the vibration gear rod 855.

[0043] In addition, the leakage rubber material processing device 9 includes a cleaning box 91 and a transmission device 96. The interior of the cleaning box 91 is provided with a cleaning liquid. The surface of the transmission cleaning belt 97 is located in the cleaning box 91 and contacts the cleaning liquid, and can be softened and cleaned by the cleaning liquid. The surface of the cleaning box 91 is connected to the interior of the pressing base 1. The interior of the cleaning box 91 is rotatably connected to the main transmission roller 92. The surface of the main transmission roller 92 is connected to the auxiliary transmission roller 93 through the transmission cleaning belt 97. The interior of the cleaning box 91 is respectively fixedly connected with a brush seat 94 and an extrusion rod 95. The brush seat 94 is provided with bristles or a plurality of protrusions, which are mainly used for scrubbing or brushing the surface of the transmission cleaning belt 97 during transmission, so as to achieve the effect of automatic cleaning of the transmission cleaning belt 97. The transmission cleaning belt 97 receives the extrusion effect of the extrusion rod 95 during transmission at the extrusion rod 95, thereby achieving the purpose of squeezing out water from its surface, and automatically scrubbing and squeezing out water from the surface of the transmission cleaning belt 97, so as to ensure that the transmission cleaning belt 97 can repeatedly and sustainably wipe and clean the surface of the veneer and plywood.

[0044] In addition, the transmission device 96 includes a connecting tooth frame 961 and a transmission gear 964. The surface of the connecting tooth frame 961 is fixedly connected to the drying heat conducting plate 2. The connecting tooth frame 961 is controlled to move synchronously by the movement of the drying heat conducting plate 2 after being squeezed by force and the movement of elastic reset. The connecting tooth frame 961 rotates in a one-way meshing manner during the reciprocating movement, thereby achieving the purpose of the transmission gear 964 always rotating in one direction, achieving the effect of one-way transmission of the transmission cleaning belt 97, and then automatically cleaning the transmission cleaning belt 97 during transmission. The top of the connecting tooth frame 961 is fixedly connected to the connecting disk 962 through a guide rod, and the inside of the connecting tooth frame 961 is elastically connected to the one-way tooth 963 through a torsion spring.

[0045] Furthermore, the surface of the connecting tooth frame 961 is slidably connected to the inside of the pressing base 1, and a limiting groove is provided inside the connecting tooth frame 961. Both ends of the one-way tooth 963 are rotatably connected to the inside of the connecting tooth frame 961, and a protrusion is fixedly connected to the surface of the one-way tooth 963, such as Fig.11 As shown, the one-way tooth 963 is affected by the protrusion and the limit groove and can only perform one-way rotation and reset rotation after rotation in the connecting tooth frame 961. The one-way rotation is convenient for the one-way tooth 963 to give way after contacting the transmission gear 964, thereby not affecting the rotation of the transmission gear 964. The surface of the connecting disk 962 is elastically connected to the pressing base 1 through a spring. The setting of the spring facilitates the elastic reset movement of the connecting disk 962, and then facilitates the elastic reset movement of the drying heat conduction plate 2.

[0046] Furthermore, the end of the auxiliary transmission roller 93 is rotatably connected to the pressing base 1, the end of the main transmission roller 92 passes through the pressing base 1 and is fixedly connected to the inside of the transmission gear 964, and the transmission cleaning belt 97 is composed of a conveyor belt and a cleaning cloth.

[0047] When the veneer panel pressing and drying device of the present invention is in use, the veneer panel and the plywood are pressed and pasted on the drying heat-conducting plate 2, and the pressing suction cup realizes the pressing and pasting by pressing the veneer panel and the plywood downward. During the pressing, the drying heat-conducting plate 2 is forced to move downward. When the drying heat-conducting plate 2 moves to the lower position, the veneer panel and the plywood complete the pressing and pasting work. At this time, it is necessary to stand still and wait for the glue to dry and adhere. When standing still after pressing and pasting, the motor 4 and the heating tube 3 are started. The heating tube 3 heats the gas at the bottom of the drying heat-conducting plate 2, and the output shaft of the motor 4 drives the limit through the curved rod 5. The frame 6 performs linear motion up and down, and the limit frame 6 drives the air pressure push plate 7 to reciprocate in the pressing base 1, and the purpose of pushing the internal heating gas is achieved during the movement. The pushed heated gas is blown onto the drying heat conduction plate 2 to achieve the effect of drying the pressed decorative panel and plywood. The continuously flowing hot air flow is used to blow and dry the panel surface, so as to achieve the effect of automatic drying, increase the drying rate of the glue, and promote the adhesion rate after pressing. During the heating and drying of the heating tube 3, the heating gas is continuously pushed to promote the continuous replacement of the heat flow and improve the drying effect. At the same time, when the curved rod 5 rotates, the toothed belt 862 and the auxiliary toothed roller 863 are connected through the active toothed roller 861. When the auxiliary toothed roller 863 rotates, it drives the reciprocating screw 81 fixedly connected inside it to rotate. The rotation of the reciprocating screw 81 drives the sliding seat 82, which is slidably connected on its surface and is linearly limited, to move linearly as a whole. The sliding seat 82 drives the rolling base 83 to move through the spring and the guide rod. When the rolling base 83 moves, the surface of the rotating pressure roller 84, to which the end of the rolling base 83 is rotatably connected, contacts the bottom of the drying heat conducting plate 2. The elastic force of the rotating pressure roller 84 and the sliding seat 82 squeezes the bottom of the drying heat conducting plate 2. The squeezing force received by the drying heat conducting plate 2 acts on the pressed veneer and plywood. The top of the veneer and plywood are positioned by the press, and the bottom is squeezed by the bottom of the drying heat conducting plate 2, and then In order to achieve the effect of tight extrusion and bonding, the sliding seat 82 drives the rotating pressing roller 84 on the rolling base 83 through the guide rod to roll and extrude the surface of the drying heat conductive plate 2, thereby achieving the effect of uniformly extruding the surface of the drying heat conductive plate 2. During the early pressing, the pressing of the veneer and the plywood is limited by the shape of the press. The area contacted and squeezed by the press is pressed tightly, but there will be gaps and bubbles in the non-contact area. The surface of the drying heat conductive plate 2 is rolled evenly to further achieve the effect of comprehensive and uniform extrusion of the pressing area of ​​the veneer and the plywood, thereby achieving the effect of reducing the problem of gaps and bubbles, improving the connection effect of drying after pressing, and avoiding the problem of poor fixing effect of the veneer and plywood with gaps or bubbles after pressing and drying due to insufficient bonding.The roller base 83 is moving in a straight line while the rotating bin 851 connected thereto is moving. During the movement, the surface of the vibration gear 852 fixedly connected at the end of the rotating bin 851 contacts and meshes with the vibration gear rod 855. Restricted by the meshing of the vibration gear rod 855, the vibration gear 852 drives the vibration ball rod 854 on the long rod 853 to rotate in a short range through the rotating bin 851. During the rotation, the vibration ball rod 854 hits the bottom of the drying heat conducting plate 2. The impact generates vibration, which acts on the veneer and plywood on the drying heat conducting plate 2 through the transfer of the medium. By impacting and vibrating the veneer and plywood, the mixing of the glue inside the veneer and plywood is promoted, and the bubbles in the glue are compacted, so that the bubbles and gaps are quickly removed. At the same time, the connecting toothed belt 862 meshes with the rotating gear 864 during the transmission. The rotating gear 864 drives its end to slide and connect through the crankshaft 865. The limit block 866 connected and linearly limited performs reciprocating linear motion, and the limit block 866 drives the vibration gear rod 855 fixed thereon to move. When moving, the vibration gear rod 855 drives the vibration gear 852 during the meshing period thereon to rotate, and the vibration gear 852 rotates forward and backward within the meshing range, thereby achieving the effect of increasing the rotation frequency of the vibration gear 852. The vibration gear 852 drives the vibration ball rod 854 on the long rod 853 to impact the frequency through the rotating bin 851, thereby increasing the vibration mixing of the adhesive inside the veneer and the plywood, and achieving rapid removal of bubbles and gaps. The bottom of the drying heat conduction plate 2 is evenly rolled and impacted and vibrated before and after rolling, so as to achieve the purpose of uniformly pressing the veneer and the plywood. Secondary pressing is performed during the drying period to quickly remove bubbles and gaps, further achieving the purpose of improving the tight bonding between the veneer and the plywood dried after pressing, and improving the bonding effect.

[0048] When the veneer panels and plywood are squeezed and pressed downward, due to the influence of the squeezing force, the excess glue of the veneer panels and plywood will be squeezed and dripped around the panels. The veneer panels containing glue will contact the surface of the transmission cleaning belt 97 during the downward pressing, and the leaked glue will be wiped and cleaned by the transmission cleaning belt 97. The residual glue on the surface of the veneer panels and plywood before drying is wiped and cleaned to avoid the problem of the leaked glue sticking to the pressing machine after drying; at the same time, when the drying heat conduction plate 2 moves up and down, it is connected to the one-way teeth 963 on the tooth frame 961 to engage the transmission gear 964 to rotate, and the transmission gear 964 drives the transmission cleaning belt 97 and the auxiliary transmission roller 93 through the main transmission roller 92 for transmission. The transmission cleaning belt 97 that has been wiped with glue moves to the inside of the cleaning box 91 during transmission to be cleaned by the cleaning liquid and the brush holder 94. The surface of the cleaned transmission cleaning belt 97 contacts the squeezing rod 95 and is squeezed and driven. The squeezing rod 95 squeezes and removes water from the cleaned surface of the transmission cleaning belt 97, thereby automatically brushing and squeezing out water from the surface of the transmission cleaning belt 97, thereby ensuring that the transmission cleaning belt 97 can repeatedly and sustainably wipe and clean the surface of the veneer and plywood.
