[0002] Cutting machines, as a common processing equipment, are widely used in many industries such as papermaking, leather, and plastics. These machines typically contain high-speed rotating or reciprocating cutting blades, and their operation poses a high degree of danger. Therefore, providing adequate safety protection for operators is crucial.

[0003] To prevent accidents, most cutting machines are equipped with protective covers for the cutting blades. However, in actual production, cutting machines require regular maintenance, such as cleaning the cutting area and inspecting or replacing the cutting blades. Most existing protective covers are fixed to the machine body using bolts, screws, and other fasteners. During maintenance, operators must use wrenches, screwdrivers, and other tools to disassemble these fasteners one by one, and then reinstall them after maintenance is complete.

[0004] This traditional fixing method makes the installation and removal of protective covers extremely cumbersome and time-consuming, which not only reduces the efficiency of equipment maintenance but also indirectly affects the overall production schedule. More seriously, some operators, in order to save time, may neglect or forget to reinstall the protective covers after maintenance, or operate them improperly during production, all of which will lead to serious safety hazards and fail to fundamentally resolve the contradiction between convenience and safety.

[0005] Therefore, this utility model proposes a cutting machine with protective function to overcome the shortcomings of the prior art. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example 1

[0021] Please refer to Figures 1 to 5 This utility model provides a cutting machine with protective function, which aims to solve the problems of inconvenient disassembly and assembly of protective covers and difficulty in adjusting the cutting width in the prior art.

[0022] like Figure 1As shown, the cutting machine with protective function includes a worktable 1 and a cutting blade 10 disposed above the worktable 1. The worktable 1 is also provided with a conveying roller mechanism 2. The cutting machine also includes a protective mechanism, which includes a main protective cover 4 slidably connected to the worktable 1, and a left protective cover 15 and a right protective cover 6 detachably connected to both sides of the main protective cover 4. The main protective cover 4, the left protective cover 15, and the right protective cover 6 together surround the cutting blade 10. Specifically, in order to achieve the sliding connection, a T-shaped sliding block 14 is fixedly connected to the worktable 1. The bottom of the main protective cover 4 is integrally formed with a T-shaped sliding groove that slides with the T-shaped sliding block 14. In order to achieve the detachable connection, grooves are provided on both sides of the main protective cover 4. Actuating holes 21 are provided on both the left protective cover 15 and the right protective cover 6. Actuating block 5 and a spring piece 22 fixedly connected to the actuating block 5 are disposed in the actuating hole 21. The actuating block 5 is engaged in the groove under the elastic force of the spring piece 22.

[0023] To further enhance the equipment's versatility, this protective cutting machine also includes a width adjustment mechanism; please refer to the details below. Figure 1 and Figure 4 The core structure is described in detail below: The width adjustment mechanism includes two symmetrically arranged limiting plates 13 and a motor 17 for driving the two limiting plates 13 to move synchronously towards or away from each other. The motor 17 is fixedly installed inside the protective box 12. The output shaft of the motor 17 is fixedly connected to a spur gear 18. The cutting blade 10 has a gear groove 11 for accommodating and guiding the spur gear 18. Both sides of the spur gear 18 mesh with two racks 19. Each rack 19 has a limiting block 20 fixedly connected to the end away from the spur gear 18, and the limiting block 20 is fixedly connected to the corresponding limiting plate 13. Through this transmission structure, when the motor 17 is started, its output shaft drives the spur gear 18 to rotate, which in turn drives the racks 19 on both sides to move the limiting plates 13 synchronously, thereby achieving the limiting of raw materials of different widths.

[0024] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, a raw material roller device 3 is also provided on the worktable 1 to facilitate the placement of raw materials by the cutting machine; in order to ensure the stability and accurate guidance of the raw materials during the conveying process, a limiting roller 9 is also rotatably connected on the worktable 1, and the limiting roller 9 is located between the conveying roller mechanism 2 and the cutting blade 10.

[0025] As another preferred embodiment, please refer to Figure 1To ensure complete enclosure of the cutting area and operational safety, a feed inlet 16 is provided at the lower part of the left protective cover 15 for raw materials to enter; a discharge outlet 7 is provided at the lower part of the right protective cover 6 for finished products to be output after cutting; at the same time, a finished product placement area 8 is also provided on the workbench 1 downstream of the discharge outlet 7 for collecting the finished products after cutting. This design ensures the enclosure of the cutting process and the safety of the operators, while facilitating the collection of finished products.

[0026] Working principle: When protection of the cutting machine is required, the T-shaped groove at the bottom of the main protective cover 4 is slidably connected to the T-shaped groove block 14 on the worktable 1. Then, the actuating blocks 5 of the left protective cover 15 and the right protective cover 6 are aligned with the grooves on both sides of the main protective cover 4. The actuating blocks 5 automatically engage into the grooves under the elastic action of the spring piece 22, thereby fixing the main protective cover 4 to the left protective cover 15 and the right protective cover 6 to form a closed protective structure, preventing the operator from accidentally touching the cutting blade 10. If the protective cover needs to be disassembled, press the spring piece 22 to disengage the actuating blocks 5 from the grooves, and the left protective cover 15 and the right protective cover 6 can be separated from the main protective cover 4. Then the main protective cover 4 can slide out of the worktable 1 along the T-shaped groove on the T-shaped groove block 14, realizing the quick disassembly and assembly of the protective cover.

[0027] When it is necessary to adapt to the cutting of raw materials of different widths, the raw material is placed by the raw material roller device 3, the conveying roller mechanism 2 starts to convey the raw material, and the limiting roller 9 guides the raw material; the motor 17 is started, and its output shaft drives the flat gear 18 inside the protective box 12 to rotate. The flat gear 18 simultaneously drives the racks 19 on both sides to move, thereby driving the limiting block 20 and the limiting plate 13 connected to the rack 19 to move synchronously, thereby adjusting the distance between the two limiting plates 13, realizing precise limiting of raw materials of different widths, preventing the raw materials from deviating during the conveying process, so that the cutting machine can adapt to the cutting of raw materials of various widths.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
