Description

Technical Field

[0001] This utility model relates to the field of PC sheet processing equipment technology, and in particular to a cutting knife that facilitates cutting PC sheets. Background Technology

[0002] PC sheets, also known as polycarbonate sheets, are made of high-performance engineering plastic polycarbonate. They have advantages such as high strength, high transparency, high temperature resistance, and corrosion resistance, and are widely used in electronics, optoelectronics, automobiles, construction and other fields.

[0003] In the prior art, a search revealed a Chinese patent disclosing a "cutting knife for facilitating the cutting of PC sheets," application number "202022856171.8." This patent primarily utilizes a blade body, a blade holder, and at least two or more sets of pre-pressure components. The blade holder has a frame-like structure, with a support plate horizontally passing through it. The blade body is mounted on the blade holder, facing the side of the support plate used for transporting the PC sheet. A drive motor drives the blade holder to reciprocate up and down on the support plate, causing the blade body to cut the PC sheet. The pre-pressure components include a stop rod, an elastic column, and a fixing block. While this addresses the technical problem of distorted cuts and reduced quality of the finished PC sheet during cutting, directly driving the cutter with a drive motor can lead to localized stress concentration during cutting if the cutting pressure is too high, resulting in deformation or cracks. This is especially problematic when cutting thicker sheets, where the material's rigidity increases, making direct pressure from the cutter more likely to damage the material. Therefore, this invention provides a cutting knife for facilitating the cutting of PC sheets to solve the problems mentioned in the background art. Utility Model Content

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-3 This utility model provides a cutting tool for easily cutting PC sheets, comprising a base plate 1 and a cutting tool 5. A U-shaped fixing frame 2 is fixedly connected to the top of the base plate 1, and a cylinder 3 is fixedly connected to the top of the fixing frame 2. A mounting plate 4 is fixedly connected to the bottom end of the piston rod of the cylinder 3. The cutting tool 5 is mounted on the bottom of the mounting plate 4. A grooving assembly is provided on one side of the mounting plate 4. The grooving assembly includes a grooving tool 9 located on one side of the cutting tool 5 and parallel to the cutting tool 5, a first adjusting screw 6 threadedly connected to the inside of the mounting plate 4, a movable plate 7 located above the grooving tool 9, and a second adjusting screw 8 threadedly connected to the inside of the movable plate 7. The end of the first adjusting screw 6 near the movable plate 7 is rotatably connected to the movable plate 7, and the top of the grooving tool 9 is rotatably connected to the bottom end of the second adjusting screw 8.

[0023] In use, first adjust the first adjusting screw 6 and the second adjusting screw 8 according to the thickness and cutting length requirements of the PC sheet. Rotating the first adjusting screw 6 moves the movable plate 7 and the grooving blade 9, positioning the grooving blade 9 at the next cutting point on the PC sheet. Rotating the second adjusting screw 8 adjusts the height of the grooving blade 9, facilitating adjustment of the grooving depth. Activating the cylinder 3 lowers the cutter 5, and the cutter 5 and grooving blade 9 work simultaneously to complete the cutting and grooving of the PC sheet. After cutting, move the PC sheet so that the grooved area is under the cutter 5 for further cutting. The coordinated work of the cutter 5 and grooving blade 9 ensures uniform pressure on the sheet during cutting. This uniform force reduces the risk of deformation and breakage due to excessive localized stress and helps maintain the overall structural stability of the sheet.

[0024] The bottom of the cutter 5 is designed with a beveled blade, and the cutting edge of the cutter 5 has a certain bevel angle, which can create a better cutting effect during cutting and reduce deformation and damage to the PC sheet. The bottom of the grooving cutter 9 is designed with a V-shaped structure, and the tip of the blade can penetrate deep into the PC material to better form a cutting groove.

[0025] A groove 13 is provided inside the base plate 1 and below the cutter 5 for the cutter 5 to penetrate deeper. A positioning block 14 is fixedly connected to the top of the base plate 1 and to one side of the grooving cutter 9. The positioning block 14 plays an auxiliary positioning role to ensure that the PC sheet moves more smoothly on the base plate 1.

[0026] To ensure stability and accuracy during the grooving process, the grooving assembly also includes two third guide rods 12 symmetrically slidably connected inside the mounting plate 4 and two first guide rods 10 symmetrically slidably connected inside the movable plate 7. The bottom ends of the first guide rods 10 are fixedly connected to the top of the grooving cutter 9 to stabilize the grooving cutter 9. The third guide rods 12 are fixedly connected to the movable plate 7 to stabilize the movable plate 7. There are two second guide rods 11 symmetrically slidably connected inside the fixing frame 2. The bottom ends of the second guide rods 11 are fixedly connected to the mounting plate 4 to ensure the stability of the mounting plate 4 moving up and down.

[0027] In order to fix the PC sheet in place during the cutting process and prevent it from moving, the cutting blade 5 is provided with a holding assembly on the side away from the slotting blade 9. The holding assembly includes a fixed plate 17 fixedly connected to the fixed frame 2, two electric push rods 15 symmetrically fixedly connected to the bottom of the fixed plate 17, and a pressure plate 16 located at the bottom of the electric push rods 15. The bottom end of the piston rod of the electric push rod 15 is fixedly connected to the pressure plate 16. The extension and retraction of the electric push rod 15 drives the pressure plate 16 to move up and down, thereby achieving the holding and fixing of the PC sheet.

[0028] Working Principle: In operation, firstly, adjust the first adjusting screw 6 and the second adjusting screw 8 according to the thickness and cutting length requirements of the PC sheet. Rotation of the first adjusting screw 6 moves the movable plate 7 and the grooving blade 9, positioning the grooving blade 9 at the next cutting point on the PC sheet. Rotation of the second adjusting screw 8 adjusts the height of the grooving blade 9, facilitating adjustment of the grooving depth. Activating the cylinder 3 lowers the cutter 5, and both the cutter 5 and the grooving blade 9 work simultaneously to cut and groov the PC sheet. After cutting, move the PC sheet so that the grooved area is under the cutter 5 for further cutting. The coordinated work of the cutter 5 and the grooving blade 9 ensures uniform pressure on the sheet during cutting. This uniform pressure reduces the risk of deformation and breakage due to excessive localized stress and helps maintain the overall structural stability of the sheet.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
