Description

Technical Field

[0001] This utility model relates to the field of disc blade installation technology, and in particular to a disc blade quick installation and positioning device. Background Technology

[0002] In modern industrial production, disc blades are key components, widely used in various cutting and processing equipment such as metal sheet cutting machines, woodworking machinery, and paper cutting devices. The precision and ease of installation and positioning of these blades play a decisive role in production efficiency and product quality.

[0003] Currently, the traditional method of installing and positioning disc blades largely relies on manual operation. Taking a paper slitting machine as an example, when multiple disc blades need to be replaced, operators must rely on their experience and various tools to determine the installation position of each blade one by one. This process is not only time-consuming and labor-intensive, resulting in low production efficiency, but also makes it difficult to consistently control the positioning accuracy. Due to the lack of an efficient and precise positioning mechanism, in actual operation, multiple blades need to be positioned one by one, which is not only cumbersome but also prone to positioning errors. This leads to positional deviations of the blades during subsequent operation, thereby affecting cutting quality and reducing production efficiency. Utility Model Content

[0030] Example

[0031] Reference Figures 1-4 As one embodiment of this utility model, a quick installation and positioning device for a disc blade is provided, comprising:

[0032] Mounting unit 100 includes a connecting frame 101 and a support base 102 located below the connecting frame 101. The support base 102 has a cutter shaft holder 103 for holding the cutter shaft and providing stable support for the entire mounting process. Mounting unit 100 also includes symmetrical push blocks 104 and top blocks 105, both of which are arc-shaped plates adapted to the shapes of the cutter shaft and the disc blade. Push blocks 104 are located above the cutter shaft holder 103 and are connected to the support base 102 via push rods 106 fixed thereon. Springs 107 are fitted onto the push rods 106, with one end of the springs 107 abutting against the push blocks 104 and the other end against the support base 102. A limiting piece 108 is fixed to one end of the push rod 106 that passes through the support base 102. When the cutter shaft is placed between the push block 104 and the top block 105, the spring 107 pushes the push block 104 to press and fix the cutter shaft on the top block 105, ensuring that the cutter shaft will not be displaced during installation.

[0033] Positioning unit 200: Composed of a sleeve rod 201 and a screw rod 202 symmetrically arranged on the connecting frame 101. The sleeve rod 201 is fixedly connected to the connecting frame 101, providing stable guidance. The screw rod 202 is rotatably connected to the connecting frame 101, and a dial 203 is fixed to one end for easy rotation by the operator. A sliding sleeve 204 is slidably fitted on the sleeve rod 201, and a nut 205 is threadedly connected to the screw rod 202. A guide rod 206 is fixedly connected between the sliding sleeve 204 and the nut 205. Multiple positioning blocks 207 are slidably fitted on the guide rod 206. The number of positioning blocks 207 is odd. One positioning block 207 in the center is fixedly connected to the guide rod 206, while the remaining positioning blocks 207 are slidably connected to the guide rod 206. Positioning screws 208 are threadedly connected to the two edge positioning blocks 207. A slot 209 adapted to the shape of the edge of the disc blade is provided below the positioning block 207 for locking the blade and achieving positioning. The positioning block 207 is also equipped with a scissor structure 213, which consists of a connecting shaft 210, a top rod 211, and a bottom rod 212. The top rod 211 and the bottom rod 212 are rotatably connected via the connecting shaft 210, which is fixedly connected to the positioning block 207. The top rod 211 and the bottom rod 212 in two adjacent scissor structures 213 are also rotatably connected to each other. This scissor structure 213 ensures that the distance between two adjacent positioning blocks 207 remains consistent. In addition, a scale 214 is installed on one positioning block 207 in the center, and an indicator needle 215 is installed on the adjacent positioning block 207, facilitating precise adjustment of the distance between the positioning blocks 207 by the operator.

[0034] Working principle

[0035] First, place the disc blade to be installed onto the cutter shaft, then place the cutter shaft on the cutter shaft holder 103. The spring 107 pushes the push block 104 to press and fix the cutter shaft placed between the push block 104 and the top block 105. According to the specifications of the disc blade to be installed, loosen the positioning screw 208 on the edge positioning block 207 and manually adjust the position of the positioning block 207 on the guide rod 206. Due to the function of the scissor mechanism 213, the distance between two adjacent positioning blocks 207 remains consistent. The operator can use the scale 214 and the indicator needle 215 to accurately determine the spacing of the positioning blocks 207. After adjustment, tighten the positioning screw 208 to fix the edge positioning block 207. Then, manually adjust the position of the circular blade to align with the positioning block 207. Next, rotate the dial 203 to rotate the screw 202, causing the nut 205 and the sliding sleeve 204 to move on the sleeve rod 201 and the screw 202, thereby adjusting the height of the positioning block 207 on the guide rod 206. Align the slot 209 on the positioning block 207 with the edge of the circular blade, so that the blade is embedded in the slot 209, pressing the circular blade onto the cutter shaft, completing the initial fixation of the blade on the cutter shaft. Then, use tools to tighten the clamps that come with the circular blade to complete the final fixation work.
