Cutting is a crucial step in its manufacturing process, and precise, efficient cutting equipment is essential for improving production efficiency and product quality.

[0003] Cutting is an essential step in the manufacturing of PET sheets. Traditional cutting devices have several problems. For example, they cannot effectively hold the sheets during cutting, resulting in low cutting accuracy and dimensional deviations. Furthermore, some devices have low levels of automation, leading to low cutting efficiency and difficulty in meeting the needs of large-scale production. In addition, after cutting, the handling and transportation of sheets are inconvenient, increasing labor costs and production time. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for manufacturing PET sheets. By setting up a support assembly, a limiting assembly, and a three-axis truss, the device uses an electric push rod to fix and limit the sheet material, and works in conjunction with a laser cutting head for precise cutting. This solves the problems of low cutting accuracy, low efficiency, and inconvenient handling and transportation of sheets in traditional cutting devices.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a cutting device for manufacturing PET sheets, including a support assembly, a limiting assembly and a three-axis truss.

[0007] The support assembly includes two symmetrically arranged fixed seats. The top surfaces of the two fixed seats are fixedly connected to a bracket. A fixed plate is fixedly connected to the outer surface of the bracket. A first electric push rod is fixedly connected to the bottom surface of the fixed plate. A baffle is fixedly connected to the output end of the first electric push rod. A second electric push rod is fixedly installed on the bottom surface of the fixed seat.

[0008] The limiting assembly includes a connecting plate, a pressure plate is fixedly connected to the top of the connecting plate, a third electric push rod is installed on the outer surface of the connecting plate, and a clamping plate is fixedly connected to the output end of the third electric push rod.

[0009] The three-axis truss is fixedly installed on the support.

[0010] Furthermore, the top of the fixing base is provided with slots and grooves, the two ends of the connecting plate slide into the slots, the gap of the clamping plate fits into the grooves, and the bottom end of the baffle contacts the top surface of the fixing base.

[0011] Furthermore, a hook is fixedly connected to the outer surface of the pressure plate, and a latch is fixedly connected to the outer surface of the fixing base, with the hook and latch being snapped together.

[0012] Furthermore, a laser cutting machine is mounted on a fixed base, and a laser cutting head is installed on the sliding end of the three-axis truss. The laser cutting machine is electrically connected to the laser cutting head.

[0013] Furthermore, a conveyor is fitted between the two fixed seats with a gap.

[0014] This utility model has the following beneficial effects:

[0015] 1. Improved cutting accuracy: The third electric push rod in the limiting component drives the clamping plate to clamp the board. At the same time, the pressure plate is fixed to the fixed base by hooks and buckles, further ensuring the stability of the board.

[0016] 2. Improved cutting efficiency: The three-axis truss configuration allows the laser cutting head to move flexibly in three directions, enabling it to quickly and accurately reach the cutting position. Moreover, the laser cutting machine, in conjunction with the laser cutting head, achieves a fast cutting speed, completing the cutting task in a short time. In addition, the conveyor facilitates the transport of the sheet material, realizing the continuity of cutting and transport, and improving overall production efficiency.

[0017] 3. Easy to operate and maintain: The device uses an electric push rod to control the movement of components such as baffles and clamps, making it simple and convenient to operate. The structure between each component is clear, making it easy to install and disassemble. In case of equipment failure, it can be quickly inspected and maintained, reducing downtime and maintenance costs.

[0018] 4. High adaptability: By adjusting the extension length of the second electric push rod, it can adapt to plates of different thicknesses. At the same time, according to the cutting requirements, the position and cutting path of the laser cutting head can be flexibly adjusted through the three-axis truss, which can meet the cutting requirements of various specifications and shapes, and has strong adaptability and versatility.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 This utility model provides a technical solution: a cutting device for manufacturing PET sheets, including a support assembly 1, a limiting assembly 2 and a three-axis truss 3.

[0029] The support assembly 1 includes two symmetrically arranged fixed seats 101. The top surfaces of the two fixed seats 101 are jointly fixedly connected to a bracket 104. A three-axis truss 3 is fixedly installed on the bracket 104. A fixed plate 105 is fixedly connected to the outer surface of the bracket 104. A first electric push rod 106 is fixedly connected to the bottom surface of the fixed plate 105. A baffle 107 is fixedly connected to the output end of the first electric push rod 106. A second electric push rod 108 is fixedly installed on the bottom surface of the fixed seat 101. The top of the fixed seat 101 is provided with a slot 102 and a groove 103. A laser cutter 5 is installed on one of the fixed seats 101. The three-axis truss 3, the laser cutter 5, and the laser cutting head 4 are selected according to the corresponding specifications and models of equipment. The sliding end of the three-axis truss 3 is equipped with the laser cutting head 4. The laser cutter 5 is electrically connected to the laser cutting head 4. A conveyor 8 is fitted between the two fixed seats 101 with a clearance fit.

[0030] PET sheets are continuously fed into the working area via a conveyor 8 between two fixed seats. The conveyor and fixed seat 101 are fitted with a clearance to ensure that the sheets are transported in the center. The clearance design between the conveyor and the fixed seat avoids friction, reduces scratches on the sheet surface, and ensures transport stability. The first electric push rod 106 drives the baffle 107 to descend to the top surface of the fixed seat, blocking the sheet from moving forward and achieving longitudinal positioning. The baffle 107 contacts the top surface of the fixed seat 101 to form a physical limit, ensuring that the starting position of the sheet cutting is accurate.

[0031] The limiting component 2 includes a connecting plate 201, a pressure plate 202 fixedly connected to the top of the connecting plate 201, a third electric push rod 203 mounted on the outer surface of the connecting plate 201, a clamping plate 204 fixedly connected to the output end of the third electric push rod 203, both ends of the connecting plate 201 slidingly engaging with the slot 102, the clamping plate 204 clearance engaging with the groove 103, the bottom end of the baffle 107 contacting the top surface of the fixed seat 101, a hook 6 fixedly connected to the outer surface of the pressure plate 202, and a latch 7 fixedly connected to the outer surface of the fixed seat 101, the hook 6 and the latch 7 being snapped together.

[0032] The connecting plate 201 of the limiting component 2 slides into the fixing seat along the slot 102. The pressure plate 202 is quickly engaged with the latch 7 through the hook 6, initially pressing the edge of the board. The slot 102 slides to achieve the quick installation of the limiting component 2. The structure of the hook 6 and the latch 7 enhances the fixing force of the pressure plate and prevents the board from warping. The third electric push rod 203 pushes the clamping plate 204 into the groove 103 of the fixing seat, clamping the board from both sides. The gap between the clamping plate and the groove eliminates lateral displacement. The double fixing pressure plate + clamping plate ensures zero shaking of the board during cutting.

[0033] The three-axis truss 3 drives the laser cutting head 4 to move along the X / Y / Z axes according to a preset program. The laser cutting machine 5 adjusts the power parameters in real time. The high-precision guide rail of the three-axis truss works in conjunction with the servo motor, and the laser cutting head and the cutting machine are controlled synchronously to adapt to PET sheets of different thicknesses.

[0034] After cutting, the first electric push rod 106 raises the baffle, the third electric push rod 203 retracts the clamping plate, the limit component 2 is pulled out of the slot, and the electric push rod linkage control realizes fully automatic reset, ready for the next cycle. The second electric push rod 108 lifts the fixed seat, the conveyor 8 restarts, and sends the cut sheet out of the work area. The electric push rod and the conveyor work in sequence to avoid finished product jamming and support continuous production.
