Description

Technical Field

[0001] This utility model relates to the field of foamed board production equipment, and in particular to a continuous cutting system for the back end of a laminator. Background Technology

[0002] Currently, the cured foamed or non-foamed sheets are continuously ejected from the rear of the dual-track laminator and enter the cutting system, where they are cut to the set lengths. Generally, a disc cutting system is used when cutting rigid foam sheets with higher density and hardness, while a band saw cutting system is used when cutting rigid or flexible foam sheets with lower density and hardness. When both types of products are produced using the same dual-track laminator, the cutting system at the rear needs to be switched. Generally, the disc saw and the band saw are separate devices. When switching between them, the connecting parts, power cables, signal cables, etc. of the already installed cutting saw must be completely removed, the entire device must be moved away, and finally the other cutting saw must be moved to the installation position. After the connecting parts, power cables, signal cables, etc. are installed and tested, it is ready for use. However, the disc saw cutting system is generally relatively large and heavy, making disassembly and relocation more troublesome. Therefore, switching between the two sawing systems requires at least 2-3 days, resulting in low switching efficiency. Furthermore, frequent and extensive disassembly of equipment and wiring significantly reduces equipment lifespan. Additionally, the large-scale disassembly and hoisting process increases the risk of accidents involving personnel, compromising their safety. Therefore, it is necessary to optimize and upgrade the structure of both sawing systems to address issues such as low switching efficiency, equipment damage during switching, and operator safety. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a continuous cutting system for the back end of a laminator. When switching between two cutting methods, fewer equipment parts need to be disassembled, less disassembly and installation work is required, the conversion efficiency is high, and frequent large-scale disassembly of equipment and lines is reduced, thereby significantly improving the service life of the equipment and reducing equipment maintenance and upkeep costs.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: A continuous cutting system for the rear end of a laminator includes a base frame, a movable seat on the base frame, a C-shaped frame movably mounted on the movable seat, the C-shaped frame moving left and right on the movable seat via a transmission assembly, a band saw motor mounted on the lower front end of the C-shaped frame, a band saw drive wheel mounted on the rotating shaft of the band saw motor, the band saw drive wheel located inside the C-shaped frame, band saw driven wheels rotatably mounted on the upper front end and the rear end of the C-shaped frame, a band saw wound around the outer periphery of the band saw drive wheel and the band saw driven wheel, a lifting frame fixedly mounted on the upper front end of the C-shaped frame, a lifting arm mounted on the lifting frame, the lifting frame driving the lifting arm to move up and down, a disc saw motor mounted on the upper end of the lifting arm, a disc saw drive wheel mounted on the rotating shaft of the disc saw motor, a disc saw driven wheel rotatably mounted on the lower end of the lifting arm, a transmission belt between the outer periphery of the disc saw drive wheel and the disc saw driven wheel, a disc saw mounted on one side of the disc saw driven wheel, and the disc saw motor driving the disc saw to rotate via the disc saw drive wheel and the disc saw driven wheel;

[0005] A movable telescopic roller is installed on one side of the C-shaped frame, and a pressing bracket is installed at both the front and rear of the movable seat. The pressing bracket is a gantry frame, and pressing cylinders are evenly distributed on the crossbeam of the pressing bracket. A pressure plate is installed between the piston rod ends of the evenly distributed pressing cylinders, and the pressing cylinder drives the pressure plate to move up and down.

[0006] Furthermore, a pair of slide rails are symmetrically arranged on both sides of the upper surface of the base frame, and the movable seat is slidably arranged on the pair of slide rails. Circular saw cylinders are evenly distributed at the front end of the base frame, and the piston rods of the circular saw cylinders are correspondingly connected to the movable seat. The circular saw cylinders drive the movable seat to move back and forth.

[0007] Furthermore, a sliding groove is provided in the middle of the upper surface of the movable seat, and a lead screw is provided in the sliding groove. One end of the lead screw is connected to the follower motor for transmission. A pair of slide rails are symmetrically arranged on both sides of the upper surface of the movable seat. The C-shaped frame is slidably arranged on the pair of slide rails. The C-shaped frame and the lead screw are connected as one unit by a slider. The follower motor drives the C-shaped frame to move through the lead screw.

[0008] Furthermore, the lifting frame consists of a lifting bracket, a lifting motor, and a lifting screw; the lifting arm consists of a pair of inclined plates on both sides of the lower end of a rectangular plate, and the rectangular plate and the lifting screw are connected as one unit by a slider; the disc saw motor is mounted on the rectangular plate, and the disc saw is mounted between the lower ends of the pair of inclined plates.

[0009] Working principle: To switch from band saw cutting to disc saw cutting, simply disconnect and store the follower motor, band saw, and corresponding power and data cables. Then, reconnect the disc saw cylinder, the corresponding power and data cables, and ensure the disc saw cutting is functioning correctly. Once the disc saw cutting is successfully tested, the conversion from band saw cutting to disc saw cutting is complete. During disc saw cutting, the lifting frame moves the lifting arm downwards to the designated position. The disc saw motor drives the disc saw to rotate and cut through the disc saw drive wheel and driven wheel. The disc saw cylinder moves the moving seat on the base frame. After cutting one piece of material, the disc saw cylinder moves the moving seat back to its original position.

[0010] To switch from disc saw cutting to band saw cutting, simply disconnect and store the power and data cables corresponding to the disc cylinder and disc cutting. Then, reconnect and install the power and data cables corresponding to the follower motor, band saw, and band saw cutting. Once the band saw cutting is tested and working properly, the conversion from disc saw cutting to band saw cutting is complete. During band saw cutting, the follower motor drives the C-shaped frame to move on the moving seat via the lead screw. After cutting a piece of material, the C-shaped frame returns to its original position.

[0011] The beneficial effects of this utility model are as follows: This cutting system has both band saw cutting and disc saw cutting functions. When switching between the two cutting methods, fewer equipment parts need to be disassembled, the workload of disassembly and installation is reduced, and the conversion efficiency is high. The production switch between different products can be completed in as little as half a day. When switching between the two cutting methods within this cutting system, frequent and large-scale disassembly of equipment and lines is reduced, thereby significantly improving the service life of the equipment and reducing equipment maintenance and upkeep costs. In addition, it also reduces large-scale disassembly and hoisting, which correspondingly reduces the occurrence of collision accidents to operators and ensures the personal safety of operators. Furthermore, the entire cutting device, base device, and movable telescopic roller device are all designed as detachable structures, which facilitates overall transfer and reassembly, and also facilitates spatial position adjustment and perfect matching with the front-end laminator system, the rear-end palletizing system, and the transfer system, ensuring continuous and uninterrupted production line operation. The parts not described in detail in this utility model are existing commonly used technologies. Attached Figure Description
