[0002] The flip laminating machine is a kind of equipment specially used for the production of composite boards. It can automatically complete the flipping and pressing process of composite boards. The flip laminating machine is widely used in the production of various composite boards, such as melamine veneer boards, PVC veneer boards, etc. The flip laminating machine has the advantages of simple structure, easy operation, low energy consumption, etc., and is suitable for mass production.

[0003] When the existing flip-panel laminating machine produces composite boards, it only directly laminates two substrate boards (single bonding and pressing, with a reinforcing layer provided between the two to increase the strength of the composite board). Since the two substrate boards are connected by a colloid, direct pressing will cause the colloid between the two substrate boards to be unable to flow freely due to the small flow space, resulting in uneven distribution of the colloid. At the same time, it is difficult to discharge the bubbles in the colloid between the two substrate boards, which ultimately leads to low production quality of the composite board.

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation mode of the present invention is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are elaborated to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] like Figure 1-Figure 3 and Figure 5 As shown, it is an embodiment of the present invention, which proposes a flap laminating machine for composite board production to solve the problem that when two substrates 101 are directly laminated in the prior art, the colloid is difficult to be evenly distributed between the two substrates and the edges and corners are prone to cracking, including: a frame 1, the frame 1 is fixedly connected to a support rod; a roller system 2 and a power system 3, both installed on the frame 1, for transporting the substrate 101; a deflection shaft 4, rotatably connected to the support rod on the frame 1; a flap frame 5, fixedly connected to the deflection shaft 4; a plurality of mounting members 6, which are arranged at intervals and are all installed on the flap frame 5, and the mounting members 6 located on the outside are slidable with the flap frame 5. The suction cups 7 are arranged in a plurality and are respectively mounted on adjacent mounting parts 6. There are multiple suction cups 7 on the same mounting part 6, which are used to improve the stability when the substrate 101 is adsorbed and fixed. An intermediate tube is connected between adjacent suction cups 7, and the intermediate tube is connected to an external air pump. A driving mechanism is arranged on the frame 1, and is used to make the deflection shaft 4 and the frame 1 rotate relative to each other. A limiting mechanism is arranged on the frame 1, and is used to make the outer mounting part 6 and the flip frame 5 slide relative to each other. A transfer mechanism is arranged on the frame 1, and is used to transfer the substrate 101.

[0027] In the above scheme, the frame 1 is welded by square steel and steel section, the purpose is to ensure the stable flipping and compounding process of the substrate 101, the roller system 2 is composed of a number of rollers connected by sprocket chain transmission, the deflection shaft 4 is fixedly connected to the rear side of the flip frame 5, the suction cup 7 is a soft material, and the suction cup 7 on the mounting part 6 slidably connected to the flip frame 5 cannot be deformed in the direction perpendicular to its own axis, so that the substrate 101 and the flip frame 5 can slide relative to each other, and the power system 3 provides power to the roller system 2, so that the substrate 101 placed on the roller system 2 (the upper side of the substrate 101 has been arranged with the colloid required for subsequent compounding) moves to the right. After the substrate 101 moves to the right to the area above the transfer mechanism, the power system 3 stops running and uses the transfer mechanism to transport the substrate 101 forward. After the transportation is completed, the external air pump is used to The suction cup 7 generates negative pressure to adsorb and fix the substrate 101. After the fixation is completed, the roller system 2 continues to transfer the new substrate 101 to the right. After the new substrate 101 also moves to the right to the area above the transfer mechanism, the interlayer 102 is placed on the upper side of the new substrate 101, and then the previous substrate 101 is flipped by the driving mechanism to composite the two substrates 101. During the composite process, the limiting mechanism is used to make the outer mounting part 6 and the flip frame 5 slide relative to each other, even if the upper substrate 101 and the flip frame 5 slide relative to each other, so that the colloid between the two substrates 101 is rubbed during the contact process of the two substrates 101, which promotes the redistribution and flow of the colloid between the two substrates 101, so that it can cover the entire bonding surface more evenly, while eliminating surface bubbles, thereby improving the composite quality of the composite board and making the bonding of the composite board firm.

[0028] like Figure 2-Figure 5 As shown, the driving mechanism includes: a motor 801, installed on the frame 1; a gear set 802, arranged between the deflection axis 4 and the output shaft of the motor 801; a support frame 803, fixedly connected to the frame 1; a limiting mechanism includes: a limiting frame 901, fixedly connected to the frame 1, the limiting frame 901 is provided with a limiting groove 902, the limiting groove 902 is composed of an arc groove and a wavy groove connected to each other, and the center of the arc groove coincides with the axis of the deflection axis 4, and the mounting member 6 slidably connected to the flap frame 5 is fixedly connected with a column 903, and the column 903 is limitedly matched with the limiting groove 902; the transfer mechanism includes: a hydraulic push rod 1001, installed on the frame 1; a mounting frame 1002, fixedly connected to the telescopic end of the hydraulic push rod 1001; a plurality of conveying modules 1003 are arranged at intervals, all of which are installed on the mounting frame 1002, and are used to transfer the substrate 101 to the support frame 803.

[0029] In the above scheme, the gear set 802 is composed of a first gear and a second gear meshing with each other, the first gear is fixedly connected to the output shaft of the motor 801, the second gear is fixedly connected to the deflection shaft 4, and the number of teeth of the first gear is less than the number of teeth of the second gear, and is used for low-speed transmission to the deflection shaft 4. The upper side surface of the flap frame 5 and the upper side surface of the support frame 803 are both inclined surfaces (with Figure 3 Taking the direction shown as an example, with the axis of the deflection shaft 4 as the rotation center, it is tilted to the lower right), and the flap frame 5 and the support frame 803 are in contact and matched to allow the substrate 101 to pass smoothly. A boss is provided at the front of the upper side of the support frame 803 to limit the substrate 101. The wavy groove is located on the side of the limit frame 901 away from the support frame 803. The conveying module 1003 is located between two adjacent rollers. After the substrate 101 moves to the right to the area above the transfer mechanism, the telescopic end of the hydraulic push rod 1001 drives the conveying module 1003 to move upward through the mounting frame 1002. After the conveying module 1003 contacts the substrate 101, the conveying module 1003 drives the substrate 101 to move upward together. When the substrate 101 moves upward to a point higher than the highest point on the upper side of the flip frame 5, it stops. Then, the conveying module 1003 transfers the substrate 101 forward. After the substrate 101 is transferred to the upper side of the support frame 803, the substrate 101 slides forward and downward along the upper inclined surface of the support frame 803 under the action of its own gravity until the substrate 101 contacts the boss on the support frame 803 and stops moving. Then, the suction cup 7 adsorbs and fixes the substrate 101.

[0030] After the suction cup 7 fixes the substrate 101, the motor 801 transmits torque to the deflection shaft 4 through the gear set 802, so that the deflection shaft 4 drives the flap frame 5 to rotate counterclockwise (in degrees). Figure 3 Taking the main viewing direction as an example), the flip frame 5 drives the mounting part 6 and the suction cup 7 thereon to rotate counterclockwise together, and the substrate 101 rotates counterclockwise together. During the process, the column 903 slides in the limit groove 902. When the column 903 slides to the wavy groove area, the opposite sides of the two substrates 101 just fit together. Then the column 903 starts to move back and forth under the action of the wavy groove, and the column 903 drives the mounting part 6 to move back and forth together. The mounting part 6 drives the substrate 101 (the upper one) to move back and forth together through the suction cup 7, so that the two substrates 101 can slide relative to each other in the horizontal direction, rub the colloid between the two, improve the uniformity of the distribution between the colloid and the two substrates 101, and thus improve the production quality of the composite board.

[0031] like Figure 4 and Figure 5As shown, it also includes: a sliding member 1101, which is slidably connected to the frame 1, and a first elastic element 1102 is fixedly connected between the sliding member 1101 and the frame 1; a first rod 1103, which is fixedly connected to the sliding member 1101; a first limiting rod 1104, which is fixedly connected to the sliding member 1101; a second limiting rod 1105, which is fixedly connected to the flap frame 5, and the second limiting rod 1105 is squeezed and matched with the first limiting rod 1104, and the second limiting rod 1105 is an arc-shaped rod, and its own curvature changes continuously, which is used to squeeze the second limiting rod 1105 to different degrees.

[0032] In the above scheme, there are two sliding members 1101 arranged in a mirror image for force balance, the first limit rod 1104 is fixedly connected between the two sliding members 1101, the first elastic element 1102 is a tension spring, and it is initially in a stretched state, for applying tension to the sliding member 1101, and during the counterclockwise rotation of the flip plate frame 5, the flip plate frame 5 drives the second limit rod 1105 to rotate counterclockwise together, the second limit rod 1105 gradually loses the squeeze on the first limit rod 1104, and the sliding member 1101 begins to move leftward (with a tension force of the first elastic element 1102) under the action of the tension of the first elastic element 1102. Figure 4 The sliding member 1101 drives the first rod 1103 to move to the left together. After the first rod 1103 contacts the substrate 101 (below), the first rod 1103 drives the substrate 101 to move to the left together, so as to adjust the position of the substrate 101, so that after the two substrates 101 are bonded, the edges of the two substrates overlap with each other, so as to improve the production quality of the composite board.

[0033] like Figure 6-Figure 8 As shown, it also includes: two second rods 1201, which are arranged in a mirror image, and the flap frame 5 is fixedly connected with two support rods arranged in a mirror image. The two second rods 1201 are respectively slidably connected to the adjacent support rods on the flap frame 5, and a second elastic element 1202 is fixedly connected between the second rod 1201 and the flap frame 5; two limiting columns 1203, which are arranged in a mirror image and are respectively fixedly connected to the adjacent second rods 1201; and limiting members 1204, which are two arranged in a mirror image and are respectively fixedly connected to the adjacent limiting frames 901, and the limiting members 1204 are squeezed together with the limiting columns 1203.

[0034] In the above scheme, the second elastic element 1202 is a spring, which is used to reset the second rod 1201. The limiting member 1204 is provided with an inclined surface, which is squeezed and matched with the limiting column 1203 to make the second rod 1201 and the flap frame 5 slide relative to each other. During the counterclockwise rotation of the flap frame 5, the flap frame 5 drives the second rod 1201 to rotate counterclockwise together through the support rod, and the second rod 1201 drives the limiting column 1203 to rotate counterclockwise together. When the limiting column 1203 rotates counterclockwise to the same position as the limiting column 1203, When the inclined surfaces on adjacent limiting members 1204 come into contact, the limiting columns 1203 are squeezed, and the two limiting columns 1203 begin to move toward each other, and the limiting columns 1203 drive the adjacent second rods 1201 to move together, so as to smooth out the colloid overflowing from both sides of the two substrates 101 due to squeezing, and distribute the overflowing colloid on the outside of the substrate 101, so as to increase the contact area between the colloid and the substrate 101, strengthen the composite strength between the two substrates 101, and thereby improve the production quality of the composite board.

[0035] like Figure 7 and Figure 8 As shown, it also includes: a plurality of extrusion plates 1301 arranged at intervals, respectively slidably connected to adjacent second rods 1201, a third elastic element 1302 is fixedly connected between the extrusion plate 1301 and the second rod 1201, a diaphragm 1303 is fixedly connected between the extrusion plate 1301 and the second rod 1201, the second rod 1201, the extrusion plate 1301 and the diaphragm 1303 are all made of polytetrafluoroethylene, which is used to reduce the adhesion of colloid during the production process of the composite board; third limiting rods 1304, the number of which is the same as the number of the extrusion plates 1301, and they are all fixedly connected to the frame 1, and the third limiting rods 1304 are extruded and matched with the extrusion plates 1301.

[0036] In the above scheme, the extrusion plate 1301 is provided with a protrusion, the third elastic element 1302 is a tension spring, and is used to reset the adjacent extrusion plate 1301, and the third limiting rod 1304 is provided with an inclined surface, and the inclined surface is pressed and matched with the protrusion on the extrusion plate 1301, so as to make the extrusion plate 1301 and the second rod 1201 slide relative to each other. During the counterclockwise rotation of the second rod 1201, the second rod 1201 drives the extrusion plate 1301 to rotate counterclockwise together. After the extrusion plate 1301 rotates counterclockwise until the protrusion on it contacts the inclined surface on the third limiting rod 1304, the same second rod 1201 The two extrusion plates 1301 start to move towards each other, so as to smooth out the colloid overflowing between the two substrates 101, so that the overflowing colloid covers the four corners of the two substrates 101, so as to further compound the four corners of the substrates 101, and prevent cracking due to stress concentration at the four corners, so as to improve the production quality of the composite board. During the process, the diaphragm 1303 always isolates the "gap" between the adjacent extrusion plates 1301 and the adjacent second rods 1201, and prevents the colloid overflowing from the two substrates 101 from entering therein, causing the parts to stick to each other, and affecting the normal progress of the compounding process.
