Description

Technical Field

[0001] The present application relates to the technical field of cardboard film pressing, and in particular to a cardboard conveying film pressing device. Background Art

[0002] Laminated paperboard is a material with a film coated on the surface of paperboard, which is usually used in packaging, printing and decoration. This film can be plastic, metal, ceramic or other materials, which can provide waterproof, moisture-proof, wear-resistant, corrosion-resistant and other properties, and also has beautiful visual effects. In the manufacturing process of laminated paperboard, a special glue is first coated on the surface of the paperboard, and then the film material is evenly laid on the surface of the paperboard, and the film and paperboard are firmly bonded by hot pressing or cold pressing. This treated paperboard can not only improve the packaging quality of the product, but also increase the added value of the product, meeting the needs of different industries for packaging materials.

[0003] The inventors have discovered that there are at least the following problems in this technology. Most of the common embossing devices for coated cardboard on the market currently have simple structures and certain functional deficiencies that need to be improved. For example, when a pressing belt rolls on the cardboard, the fixed position of the pressing belt will cause the cardboard to be distributed in a trapezoidal shape. Due to the steps of the trapezoid, the step positions cannot be squeezed by the pressing belt, causing the film to warp and affecting the quality after film pressing. Therefore, a cardboard conveying film pressing device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present application provides a cardboard conveying film pressing device, which has the advantages of arranging a carpet on the outer surface of a pressing belt and adopting a height-adjustable pressing belt to ensure that during the film pressing process, the deformation of the carpet can also have a good squeezing effect on the position of the cardboard steps, thereby reducing the warping of the film, etc. It solves the problem that when the pressing belt rolls on the cardboard, the fixed position of the pressing belt causes the cardboard to be distributed in a trapezoidal shape, and the step position cannot be squeezed by the pressing belt due to the trapezoidal steps, causing the film to warp, resulting in affected quality after film pressing.

[0005] In order to achieve the purpose of better laminating effect of the above-mentioned paperboard after lamination and less prone to warping of the film edge, the present application provides the following technical solutions: a paperboard conveying and laminating device, comprising a conveying bracket, a support frame installed on the top of the conveying bracket, and an auxiliary structure installed inside the support frame;

[0006] The auxiliary structure includes a motor installed inside the support frame, a screw fixedly connected to one end of the motor output shaft, an outer surface adjustment block movably connected to the screw, an adjustment frame fixedly connected to the outer surface of the adjustment block, a replacement plate installed inside the adjustment frame, a rotating roller rotatably connected to the inside of the replacement plate, and a pressing belt sleeved on the outer surface of the rotating roller.

[0007] In the present application, when the coated cardboard is being laminated, it is placed on the top of the conveying bracket and conveyed to the bottom of the pressing belt, and then the motor is started to drive the screw to rotate, so that the adjustment block slides inside the support frame, and then the pressing belt is adjusted to a suitable height. The pressing belt presses the edge of the coated cardboard to avoid edge warping as much as possible, thereby improving the surface quality after lamination.

[0008] Furthermore, a cardboard conveyor belt is rotatably connected inside the conveying support, and a fixing plate is fixedly connected to the top of the support frame, and the fixing plate is in a triangular shape.

[0009] The beneficial effect of adopting the above further solution is that the coated cardboard can be easily transported during the pressing process, and the setting of the fixed plate improves the stability of the support frame, ensuring that the device is prevented from falling apart during the film pressing process.

[0010] Furthermore, a sliding groove is provided inside the support frame, and the adjustment block is in a concave shape. The adjustment block slides inside the support frame through the sliding groove. A roller is rotatably connected inside the adjustment block, and the roller rolls inside the support frame.

[0011] The beneficial effect of adopting the above further solution is: ensuring that the roller can facilitate the movement of the adjustment block during the up and down movement, converting the sliding motion into rolling motion, reducing the resistance caused by friction, and improving the convenience during adjustment.

[0012] Furthermore, a guide block is fixedly connected inside the adjusting frame, and the replacement plate is installed inside the adjusting frame through the guide block. A limiting block is fixedly connected inside the adjusting frame, and the replacement plate is limited inside the adjusting frame through the limiting block.

[0013] The beneficial effect of adopting the above further scheme is that after the replacement plate is installed inside the adjustment frame, the guide block and the limit block exist, which can facilitate the installation and replacement of the replacement plate when it is installed, and provide convenience for subsequent maintenance of the equipment.

[0014] Furthermore, the number of the rotating rollers is several, and a carpet is bonded to the outer surface of the pressing belt, and the thickness of the carpet is three millimeters.

[0015] The beneficial effect of adopting the above further scheme is that the outer surface of the pressing belt is bonded to the carpet. Since the thickness and weight of the carpet are relatively suitable and the carpet has a large deformation, the deformation of the carpet can also have a good squeezing effect on the position of the cardboard step, thereby reducing the warping of the film and improving the practicality of the device.

[0016] Furthermore, the outer surface of the adjustment frame is fixedly connected to a mounting plate, the interior of the mounting plate is rotatably connected to a stud, the outer surface of the stud is threadedly connected to a plug-in plate, the outer surface of the adjustment frame is fixedly connected to a mounting block, and the outer surface of the mounting block is elastically connected to a limiting column.

[0017] The beneficial effect of adopting the above further scheme is that when the pressure belt is damaged, the stud can be rotated to drive the plug-in plate out of the interior of the replacement plate, and the limit column is separated from the plug-in plate. The replacement plate can be disassembled and the damaged pressure belt can be replaced with a new one, thereby increasing the service life of the device.

[0018] Furthermore, the mounting plate is in the shape of an L-shaped plate, the back of the plug-in plate is slidably connected to the inner wall of the mounting plate, the plug-in plate is in the shape of an L-shaped plate, a plug-in slot is provided inside the replacement plate, and the plug-in plate is movably connected to the replacement plate through the plug-in slot.

[0019] The beneficial effect of adopting the above further solution is that after the replacement plate is installed inside the adjustment frame, it can be installed and limited via the plug-in plate, so as to avoid falling off as much as possible during the membrane pressing process.

[0020] Furthermore, a limit slot is provided inside the plug board, and the limit column is located inside the plug board through the limit slot.

[0021] The beneficial effect of adopting the above further solution is that after the plug-in board limits the replacement plate, the outside can be blocked by the limiting column, thereby reducing the displacement caused by vibration and the subsequent loosening.

[0022] Compared with the prior art, the present application provides a cardboard conveying film pressing device, which has the following beneficial effects:

[0023] 1. The cardboard conveying film pressing device, when the laminated cardboard is being laminated, is placed on the top of the conveying bracket and conveyed to the bottom of the pressing belt, and then the motor is started to drive the screw to rotate, so that the adjustment block slides inside the support frame, and then the pressing belt is adjusted to a suitable height. The pressing belt presses the edge of the laminated cardboard to avoid edge warping as much as possible and improve the surface quality after lamination.

[0024] 2. When the pressing belt of the cardboard conveying film pressing device is damaged, the stud can be rotated to drive the plug-in plate to detach from the inside of the replacement plate, and the limit column is separated from the plug-in plate. The replacement plate can be disassembled and the damaged pressing belt can be replaced with a new one, thereby improving the service life of the device. BRIEF DESCRIPTION OF THE DRAWINGS
