For example, the material to be pressed may be PVC/PETG/ABS/PC/epoxy resin/copper clad foil, etc. However, after the press-fitting, the laminated product adheres to the belt, and is difficult to disassemble and assemble, continuous production is difficult to achieve, and production efficiency is low.

The laminating device provided by the invention can realize continuous production and improve the production efficiency by peeling the laminated product from the transmission belt through the peeling plate after the laminated product is formed.

The invention provides a laminating device, which is used for combining at least two materials M to be laminated; referring to fig. 1, 3 and 4, the laminating apparatus includes a laminating assembly, a feed assembly and a peeling assembly.

The laminating assembly constructs a pressing gap which is used for limiting the thickness of the at least two materials to be pressed after pressing.

The pressing gap is a material passing gap extending in the first direction, and the material to be pressed can move in the first direction; in the second direction, the stitching gap can be adjusted in height, so that it can be used to produce stitched products P of different thicknesses. Typically, the lamination assembly includes an upper platen (e.g., the second hot platen 200a and the second cold platen 200b) and a lower platen (e.g., the first hot platen 100a and the first cold platen 100 b); the upper pressing plate and the lower pressing plate are arranged in parallel and are kept to have a certain gap in the second direction, namely the pressing gap.

The feeding assembly comprises a first driving wheel set, the first driving wheel set comprises a first rear driving wheel 400b-1, and the first rear driving wheel 400b-1 is located at the rear end of the pressing gap where the at least two materials to be pressed move in the first direction.

The feeding assembly is used for driving the material to be pressed to enter the pressing gap, and the material is pressed into a laminated product based on the pressure of the laminating assembly. Generally, the feeding assembly comprises a first driving wheel set and a second driving wheel set; the first drive wheel set includes a first rear drive wheel 400b-1 and a first front drive wheel 400 b-2; the second drive wheel set includes a second rear drive wheel 400e-1 and a second front drive wheel 400 e-2. The first rear driving wheel 400b-1 is located at the rear end of the pressing gap where the at least two materials M to be pressed move in the first direction; the second rear driving wheel 400e-1 is located at the rear end of the pressing gap where the at least two materials M to be pressed move in the first direction; and, the axes of the first rear driving wheel 400b-1 and the second rear driving wheel 400e-1 are parallel to each other and are spaced apart in the second direction. The first front driving wheel 400b-2 is positioned at the front end of the pressing gap where the at least two materials M to be pressed move in the first direction; the second front driving wheel 400e-2 is positioned at the front end of the pressing gap where the at least two materials M to be pressed move in the first direction; and, the axes of the first front driving wheel 400b-2 and the second front driving wheel 400e-2 are parallel to each other and spaced apart in the second direction. The first rear drive wheel 400b-1 and the first front drive wheel 400b-2 are connected by a belt 400a, and the second rear drive wheel 400e-1 and the second front drive wheel 400e-2 are connected by another belt 400 a; generally, the first rear driving wheel 400b-1 and the second rear driving wheel 400e-1 are used as driving wheels to drive the at least two materials M to be pressed into the pressing gap to be pressed into the laminated product P.

It should be noted that the feeding assembly further includes a driving motor 400c for transmitting power to the first rear driving wheel 400b-1 and the second rear driving wheel 400e-1 through a gear set so as to move the at least two materials to be pressed M in the first direction in the re-laminating gap.

The shape of the peeling plate 600a is preferably square. Due to the influence of gravity and the influence of the power of the feeding assembly, the peeling plate 600a leans against the first rear driving wheel 400b-1, namely: the stripper plate 600a extends from its abutting contact surface with the first rear drive wheel 400b-1 towards the side of the first rear drive wheel 400b-1 facing away from the flash gap and has a tendency to approach the ground when extended. Generally, the stripper plate 600a is tangent to the first rear drive wheel 400 b-1; when the pressed product P and the belt are moved to a tangent (or a tangent plane) defined by the peeling plate 600a and the first rear driving wheel 400b-1, the pressed product P and the belt are peeled off by the peeling plate 600a, the pressed product P is sent to the peeling plate 600a based on power, and the belt is moved to the first front driving wheel 400a-1 direction (the direction opposite to the first direction) based on power. Thus, after the laminated product P is molded, the peeling plate 600a peels the laminated product P from the belt, thereby enabling continuous production and improving production efficiency.

It is noted that, in general, the lamination assembly includes a first lamination 100 (e.g., the second hot platen 200a and the second cold platen 200b) and a second lamination 200 (e.g., the first hot platen 100a and the first cold platen 100 b); the first laminate structure 100 and the second laminate structure 200 are arranged in parallel and are maintained with a certain gap in the second direction, i.e. a nip gap.

The pressing member 300 may be a telescopic member such as an air cylinder, a hydraulic cylinder, or an electric push rod. One end of which is fixedly connected (e.g., threaded, plugged), etc. to a side of the second laminate structure 200 facing away from the first laminate structure 100. The size of the pressing gap in the second direction can be adjusted through the jacking assembly 300; more importantly, the pressure of the material M to be laminated between the first laminated structure 100 and the second laminated structure 200 is adjusted.

The laminating device firstly adopts a hot pressing process to carry out hot pressing on at least two materials to be laminated in a material passing hot pressing gap, and then the materials are seamlessly connected to a material passing cold pressing gap for cold pressing.

Note that, the first laminated structure 100 includes a first hot press plate 100 a; the second lamination structure 200 comprises a second hot press plate 200a, and the first hot press plate 100a and the second hot press plate 200a are arranged at intervals in the second direction to form the material passing hot press gap; the first lamination 100 comprises a first cold-pressed plate 100 b; the second lamination 200 comprises second cold press plates 200b, the first and second

cold press plates

The uniform array may be a square array or a circular array.

One specific embodiment of the present invention is: the first hot press plate 100a and the second hot press plate 200a are pressed together by controlling the magnitude of the pressure applied by the plurality of first pressing mechanisms 300a (such as hydraulic cylinders), and the magnitude of the pressure applied to at least two materials M to be pressed is controlled, so that the preheating, pressing and pressure maintaining composite lamination functions used in the production process are achieved.

One specific embodiment of the present invention is: the first cold pressing plate 100b and the second cold pressing plate 200b are pressed together by controlling the pressure applied by a plurality of second pressing mechanisms 300b (such as hydraulic cylinders), and the pressure is applied to at least two materials M to be pressed, so that the functions of cooling, pressure maintaining and forming of the production process are achieved.

It should be noted that a preheating channel is arranged in the preheating assembly 500, and the temperature in the preheating channel is lower than the temperature of the overfeeding hot-pressing gap.

Through preheating, the temperature difference gradient is effectively reduced, so that at least two materials to be pressed can be uniformly heated, the pressing of the pressed product P is tight, the binding force is uniform, and the quality of the pressed product P is improved. Meanwhile, through preheating, the heating time of at least two materials M to be pressed in the material passing hot-pressing gap can be shortened, and therefore the production efficiency is improved.
