[0025] The cutting mechanism 2 includes a U-shaped seat 201 fixedly arranged at the center of the top of the mounting plate 101. Moving plates 204 are correspondingly arranged on the left and right sides inside the U-shaped seat 201. The tops of the two moving plates 204 extend above the U-shaped seat 201 and are slidably connected thereto. A biaxial motor 206 is fixedly connected to the center of the top of the U-shaped seat 201. Bidirectional threaded rods 205 are fixedly connected to the output ends on the left and right sides of the biaxial motor 206. The bidirectional threaded rods 205 are rotatably arranged on the top of the U-shaped seat 201. The bidirectional threaded rods 205 are threadedly connected to the inner walls of the moving plates 204. A cutting knife 208 is fixedly connected to the bottom of the moving plate 204 through a fastener.

[0026] The conveyor mechanism 1 is composed of a mounting plate 101 and a plurality of conveyor rollers 104 rotatably connected at equal intervals, and is responsible for smoothly feeding the softening materials to be cut into the cutting area. The equal interval distribution of the conveyor rollers 104 helps the uniform transmission of the materials, reducing offset or wrinkles during the transmission process. The biaxial motor 206 is installed at the center of the top of the U-shaped seat 201, and the output ends on the left and right sides are respectively connected with bidirectional threaded rods 205. By the forward and reverse rotation of the biaxial motor 206, the bidirectional threaded rods 205 are driven to rotate, thereby driving the moving plates 204 threadedly connected thereto to move in opposite directions, realizing the dynamic adjustment of the distance between the cutting knives 208. Through the cooperation of the biaxial motor 206 and the bidirectional threaded rods 205, the distance between the cutting knives 208 can be conveniently adjusted, suitable for materials and product specifications of different widths, greatly improving the versatility and production efficiency of the equipment. The design of screw drive and sliding connection ensures the smoothness and accuracy of the movement of the cutting knife 208, which is beneficial to improving the cutting quality and the consistency of the finished products. The dynamic adjustment of the distance between the cutting knives 208 is realized through a clever mechanical structure, which not only improves the flexibility and accuracy of the cutting device, but also simplifies the operation process, and is very suitable for the mass production and quality control of automotive instrument softening materials.

[0027] On the left and right sides of the mounting plate 101, a plurality of support legs 102 are fixedly connected. On the top of the mounting plate 101, a plurality of mounting grooves 103 are equidistantly arranged. Inside the plurality of mounting grooves 103, conveying rollers 104 are rotatably connected.

[0028] The design of the support legs 102 and the mounting plate 101 provides a stable foundation, ensuring the stability and reliability of the device during high-speed cutting, reducing cutting errors caused by vibration or instability. The equidistantly distributed conveying rollers 104 ensure the smooth and efficient transmission of materials, reducing potential damage to the materials during transmission, and ensuring the integrity and consistency of the materials before cutting. These design details together constitute an efficient, stable and easy-to-maintain conveying mechanism 1, providing a solid foundation for the quantitative cutting of automotive instrument softening materials and being an indispensable part of the entire cutting device.

[0029] Inside the inner wall of the conveying roller 104, a rotating rod 105 is fixedly connected. One end of the rotating rod 105 extends outside the mounting plate 101 and is rotatably connected thereto. At the leftmost end, the rotating rod 105 is fixedly connected with a power motor 106, and the power motor 106 is fixedly arranged on one side of the mounting plate 101.

[0030] The power motor 106 drives the conveying roller 104 to rotate through the rotating rod 105, which can precisely control the conveying speed, ensuring that the materials enter the cutting area at a set speed and rhythm, and avoiding material accumulation or stretching caused by uneven speed, which affects the cutting quality and production efficiency.

[0031] On the surface of one end of the plurality of rotating rods 105, pulley 107 is fixedly sleeved. Between the surfaces of the plurality of pulleys 107, the same belt 108 is drivingly connected.

[0032] Through the combination of the belt 108 and the pulley 107, the output power of the power motor 106 can be evenly distributed to all the conveying rollers 104, ensuring that the rotation speeds of all the conveying rollers 104 are consistent, avoiding uneven material conveyance caused by different rotation speeds of individual rollers, and improving the smoothness and consistency of material conveyance.

[0033] On the left and right sides of the bottom of the U-shaped seat 201, a plurality of equally spaced electric push rods 202 are fixedly connected. The plurality of electric push rods 202 are fixedly arranged on the top of the mounting plate 101.

[0034] The electric push rods 202 are fixedly connected to the left and right sides of the bottom of the U-shaped seat 201 and are equally spaced. Their main function is to adjust the vertical position of the U-shaped seat 201 and its upper components including the cutting knife 208 in an electric drive manner. The use of the electric push rods 202 enables the cutting mechanism 2 to perform height fine-tuning according to the thickness and hardness of different softening materials to ensure the best contact state between the cutting knife 208 and the material surface, improving the cutting accuracy and efficiency.

[0035] On the left and right sides of the top of the U-shaped seat 201, there are corresponding slots 203 opened. The slots 203 are slidably connected to the moving plate 204. Inside the inner wall of the moving plate 204, a limiting rod 207 is slidably connected, and the limiting rod 207 is fixedly arranged on the top of the U-shaped seat 201.

[0036] Through the sliding connection with the slots 203, it can horizontally move inside the U-shaped seat 201. The top of the moving plate 204 extends above the U-shaped seat 201 and bears the cutting knife 208. The movement of the moving plate 204 is driven by a bidirectional threaded rod 205. By controlling the double-shaft motor 206, the adjustment of the distance between the cutting knives 208 is realized. The function of the limiting rod 207 is to further limit the lateral movement of the moving plate 204, enhance the guiding property and stability of the moving plate 204 during the horizontal movement, prevent the moving plate 204 from shaking or deviating from the track during the adjustment of the distance between the cutting knives 208, and ensure the precise alignment of the cutting knife 208 during the cutting process.

[0037] At the bottom of the moving plate 204, a positioning seat 209 is fixedly connected. The top of the inner wall of the positioning seat 209 is in contact with the top of the cutting knife 208. A positioning bolt 210 is threadedly connected between the positioning seat 209 and the cutting knife 208.

[0038] The combined design of the positioning seat 209 and the positioning bolt 210 ensures the precise fixation of the cutting knife 208 during the cutting process, avoids cutting errors caused by tool loosening or position deviation, and improves the cutting quality and the consistency of the finished product.

[0039] On the left and right sides of the inner wall of the positioning seat 209, a plurality of equally spaced fixed sleeves 211 are connected. Inside the plurality of fixed sleeves 211, a telescopic rod 212 is slidably connected. One end of the telescopic rod 212 extends outside the fixed sleeve 211 and is in contact with the left and right sides of the cutting knife 208. A spring 213 is fixedly connected between the fixed sleeve 211 and the telescopic rod 212.

[0040] The combined design of the telescopic rod 212 and the spring 213 enables the cutting knife 208 to automatically adjust the fixed state according to its own size and shape. Even when dealing with cutting knives 208 of different specifications, it can maintain a good fixed effect, improving the adaptability of the equipment and the cutting accuracy.

[0041] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
