A bearing is installed at the connection between the transmission shaft 65 and the mounting plate 62. A transmission assembly 64 is provided at the bottom of the transmission shaft 65. A gear column 68 is fixedly connected to the top of the transmission shaft 64. The transmission assembly 64 includes a fixed connection to the transmission The disc 641 at the bottom of the shaft 65 and the second sprocket 642 sleeved on the outside of the disc 641, the middle part of the outer side of the disc 641 is fixedly connected to the limit ring 644, the inner side of the second sprocket 642 is provided with a circular groove 643, the second sprocket 642 is rotatably sleeved on the outer side of the limit ring 644 through the circular groove 643, the surface of the limit ring 644 is provided with a plurality of inclined grooves 645, the inner top of the circular groove 643 is provided with a plurality of sockets 646, the inner cavities of the plurality of sockets 646 are all slidably connected with the insertion rod 648, the inner top of the socket 646 is connected to the A second spring 647 is fixedly connected between the insertion rods 648, a first sprocket 6 is fixedly connected to the outside of the first screw rod 42, a first chain 63 is meshed between the first sprocket 6 and the second sprocket 642, a connecting shaft 66 is rotatably passed through the connecting plates 3 on both sides of the unwinding roller 32 and the connecting plates 3 on both sides of the winding roller 31, and the four connecting shafts 66 are respectively installed with bearings at the connection points of the four connecting plates 3, and a first bevel gear 67 is fixedly connected to the outside of the connecting shaft 66 near the side of the vertical plate 2, and the connecting plate 3 above the first bevel gear 67 is fixedly connected to A fixed plate 69, a rotating shaft 611 is rotatably passed through the fixed plate 69, a bearing is installed at the connection between the rotating shaft 611 and the fixed plate 69, the top of the rotating shaft 611 is fixedly connected to a driven gear 610, the driven gear 610 is meshed with the gear column 68, the bottom of the rotating shaft 611 is fixedly connected to a second bevel gear 612, the second bevel gear 612 is meshed with the first bevel gear 67, the third sprocket 7 is fixedly connected to the connecting shaft 66 on the front side of the unwinding roller 32 and the winding roller 31, and a second chain 71 is meshed between the two third sprockets 7.

[0035] During operation, when the first driving motor 43 drives the first screw 42 to rotate clockwise and drives the pressing heating plate 23 to contact the substrate, the first sprocket 6 and the first chain 63 are cooperated to drive the second sprocket 642 to rotate clockwise, so that the insertion rod 648 can cross the inclined surface of the inclined groove 645, and will not drive the transmission shaft 65 to rotate, and further will not drive the unwinding roller 32 and the winding roller 31 to rotate, effectively cutting off the power transmission link of the transmission shaft 65, and the driven gear 610 slides on the gear column 68, without affecting the descent of the PVC decorative film and the composite with the substrate, and cooperates The friction between the various components is greater than the friction force of the insertion rod 648 passing over the inclined surface of the inclined groove 645, ensuring that the unwinding roller 32 is in a static locked state. After the PVC decorative film is pressed and cut, the first drive motor 43 drives the first screw rod 42 to rotate counterclockwise, driving the pressing heating plate 23 to separate from the pressed decorative plate, and cooperates with the first sprocket 6 and the first chain 63 to drive the second sprocket 642 to rotate counterclockwise, thereby cooperating with the elastic force of the second spring 647 to push the insertion rod 648 into the inclined groove 645, so that the insertion rod 648 cannot pass over the inclined groove 64 5, thereby driving the disc 641 and the transmission shaft 65 to rotate counterclockwise, and then cooperating with the transmission shaft 65 to drive the gear column 68 to rotate, so that the gear column 68 drives the driven gear 610 to rotate, and then the driven gear 610 cooperates with the rotating shaft 611 to drive the second bevel gear 612 to rotate. Since the second bevel gear 612 is engaged with the first bevel gear 67, the first bevel gear 67 is driven to rotate, and then the unwinding roller 32 is driven to rotate, and the PVC decorative film is unwound. In cooperation with the second chain 71 and the third sprocket 7, when the unwinding roller 32 rotates When the PVC decorative film is unrolled, the winding roller 31 rotates synchronously to rewind the cut PVC decorative film, so that when the pressing and heating plate 23 is reset, the new PVC decorative film is automatically pulled to the bottom of the pressing and heating plate 23 (the width of the PVC decorative film is greater than the width of the composite substrate, so that the PVC decorative film is still a connected PVC decorative film after cutting). When the next substrate is composited with the PVC decorative film, there is no need for personnel to manually pull the new PVC decorative film and the substrate for composite, which further improves the efficiency of the PVC decorative film composite.

[0036] As a further embodiment of the present invention, the opposite ends of the two connecting shafts 66 on the same side are connected to the winding roller 31 and the unwinding roller 32 through a coupling. The coupling facilitates the disassembly and assembly of the unwinding roller 32 and the winding roller 31, thereby facilitating the replacement of the PVC decorative film on the unwinding roller 32 and the cleaning of the edge PVC decorative film wound on the winding roller 31.

[0037] As a further embodiment of the present invention, the surface of the horizontal plate 25 is rotated and penetrated by first fixing bolts 29 on both sides, and the two first fixing bolts 29 are threadedly connected to the surface of the cutting knife 22. The two ends of the cutting knife 22 are rotated and penetrated by second fixing bolts 210, and the two second fixing bolts 210 are rotated and penetrated by the slider 27 and are respectively threadedly connected to the two end surfaces of the pressing and heating plate 23. The horizontal plate 25 is connected to the cutting knife 22 through the first fixing bolts 29, which facilitates the disassembly and replacement of the damaged cutting knife 22. The pressing and heating plate 23 is connected to the slider 27 through the second fixing bolts 210, which facilitates the disassembly and replacement of the damaged pressing and heating plate 23.

[0038] As a further embodiment of the present invention, the bottom of the roller conveyor 1 is fixedly connected with an adjusting plate 5, and the adjusting plate 5 is provided with a moving groove 56 at one end close to the roller conveyor 1, and a bidirectional screw rod 58 is rotatably connected between the two ends of the inner cavity of the moving groove 56 through a bearing, and a moving block 57 is slidably connected to both sides of the inner cavity of the moving groove 56, and the two moving blocks 57 are respectively threaded on the outer sides of the bidirectional screw rod 58, and the tops of the two moving blocks 57 are fixedly connected with a push rod 59, and the tops of the two push rods 59 are fixedly connected with a limit plate 52, and the limit plate 52 is placed above the roller of the roller conveyor 1, and the outer end of the adjusting plate 5 is fixedly installed with a second drive motor 51, and the driving end of the second drive motor 51 rotates through the adjusting plate 5 and is connected to the bidirectional screw rod 58 through a coupling, and the bottom of the roller conveyor 1 on one side of the adjusting plate 5 is fixedly connected with a bottom plate 53, and the end of the bottom plate 53 close to the roller conveyor 1 is fixedly connected with a push rod motor 54, The driving end of the motor 54 is fixedly connected to a blocking plate 55, and the blocking plate 55 is movably opposed to the two limit plates 52. By starting the second driving motor 51 to drive the bidirectional screw rod 58, the distance between the two limit plates 52 can be adjusted so that the distance between the two limit plates 52 is the same as the distance between the two ends of the substrate, thereby limiting the two ends of the conveyed substrate, thereby ensuring that when the substrate is pressed with the PVC decorative film, the two ends of the substrate correspond to the two ends of the cutting knife 22. When the substrate is conveyed by the roller conveyor 1, the blocking plate 55 is pushed by starting the push rod motor 54 so that its surface is at the same level as the surface of the limit plate 52, thereby the blocking plate 55 can block the conveyed substrate, ensuring that one end of the substrate corresponds to the inner end of the cutting knife 22, thereby ensuring that the conveyed substrate is placed directly under the pressing heating plate 23. When the substrate is composited, the blocking plate 55 is driven by the push rod motor 54 to be placed under the roller conveyor 1, thereby not affecting the unloading of the composite PVC decorative board.

[0039] As a further embodiment of the present invention, a plurality of arc grooves 510 are provided at the bottom of the limit plate 52, and the limit plate 52 is movably pressed against the outer side of the roller on the roller conveyor 1 through the arc grooves 510. By setting the arc grooves 510, the effect of the limit plate 52 and the roller on the roller conveyor 1 being pressed against each other is improved, thereby avoiding a large gap between the limit plate 52 and the roller that affects the transportation of the substrate.

[0040] As a further embodiment of the present invention, the connection length between the insertion rod 648 and the compressed spring is less than the depth of the socket 646, which is used to ensure that the insertion rod 648 can be completely squeezed and accommodated in the socket 646, and to ensure that the insertion rod 648 can be squeezed over the inclined surface of the inclined groove 645, and the external dimensions of the insertion rod 648 are adapted to the internal dimensions of the socket 646, which is used to avoid shaking when the insertion rod 648 is inserted into the socket 646, thereby further improving the stability of the second sprocket 642 driving the disc 641 to rotate.

[0041] Working principle of the present invention:

[0042] The unwinding roller 32 wrapped with the PVC decorative film is connected between the two connecting shafts 66 on one side through a coupling, and then the winding roller 31 is connected between the two connecting shafts 66 on the other side through a coupling. Then, one end of the PVC decorative film is pulled so that the PVC decorative film is placed on the bottom of the pressing and heating plate 23 and fixedly connected to the winding roller 31. Then, the substrate coated with glue is conveyed to the bottom of the pressing and heating plate 23 through the roller conveyor 1, and then the first drive motor 43 is started to drive the first screw rod 42 to rotate clockwise. When the pressing and heating plate 23 is driven to contact the substrate, the first sprocket 6 and the first chain 63 are cooperated to drive the second sprocket 642 to rotate clockwise, so that the insertion rod 648 can pass over the inclined surface of the inclined slot 645 without driving the transmission shaft 6 5 rotates, and thus does not drive the unwinding roller 32 and the winding roller 31 to rotate, effectively cutting off the power transmission link of the transmission shaft 65, and the driven gear 610 slides on the gear column 68, without affecting the descent of the PVC decorative film and the composite with the substrate. The friction between the various components is greater than the friction of the insertion rod 648 crossing the inclined surface of the inclined groove 645, ensuring that the unwinding roller 32 is in a static locked state, thereby driving the pressing heating plate 23, the unwinding roller 32 and the winding roller 31 to move synchronously, so that the PVC decorative film first contacts the substrate on the side coated with glue, and then continues to move downward. The pressing heating plate 23 presses the PVC decorative film on the substrate on the side coated with glue. The temperature of the pressing heating plate 23 is 65±2℃, and the pressing heating plate 23 is 0.8-1.The 2MPa pressure causes the PVC film and the adhesive layer to produce interfacial molecular penetration and bonding. Since the pressing and heating plate 23 is slidably connected to the slide groove 26 through the slider 27, the first spring 28 is compressed when the cutting knife 22 continues to move downward, thereby driving the cutting knife 22 to be set on the outside of the substrate. Since the inner size of the cutting knife 22 is adapted to the outer size of the substrate, the cutting knife 22 cuts the excess PVC decorative film around the substrate, thereby converging the laminating, pressing and cutting processes into a single-stroke operation, thereby There is no need for workers to use blades to manually trim the edges, thereby improving the production efficiency of the PVC decorative board. After the PVC decorative film is pressed and cut, the first drive motor 43 drives the first screw rod 42 to rotate counterclockwise, driving the pressing heating plate 23 to separate from the pressed decorative board, and cooperates with the first sprocket 6 and the first chain 63 to drive the second sprocket 642 to rotate counterclockwise, thereby cooperating with the elastic force of the second spring 647 to push the insertion rod 648 into the inclined groove 645, so that the insertion rod 648 cannot cross the right-angled side of the inclined groove 645, thereby driving the disc 641 and the transmission shaft 65 rotate counterclockwise, and then cooperate with the transmission shaft 65 to drive the gear column 68 to rotate, so that the gear column 68 drives the driven gear 610 to rotate, and then the driven gear 610 cooperates with the rotating shaft 611 to drive the second bevel gear 612 to rotate. Since the second bevel gear 612 is meshed with the first bevel gear 67, the first bevel gear 67 is driven to rotate, and the unwinding roller 32 is driven to rotate to unwind the PVC decorative film. In cooperation with the second chain 71 and the third sprocket 7, when the unwinding roller 32 rotates to unwind the PVC decorative film, the winding roller 31 rotates synchronously to rewind the cut PVC decorative film, so that when the pressing and heating plate 23 is reset, the new PVC decorative film is automatically pulled to the bottom of the pressing and heating plate 23 (the width of the PVC decorative film is greater than the width of the composite substrate, so that the PVC decorative film is still a connected PVC decorative film after cutting), and then when the next substrate is composited with the PVC decorative film, there is no need for personnel to manually pull the new PVC decorative film and the substrate for composite, further improving the efficiency of the PVC decorative film composite. .
