Description

Technical Field

[0001] The utility model relates to the technical field of material cutting, in particular to a flexible material cutting device. Background Art

[0002] Flexible materials are highly flexible and plastic and can be bent, stretched and twisted while maintaining their original form and properties.

[0003] After searching, the publication number is CN215366489U, which discloses a flexible material cutting device, including an operating table, a base, a pressure cover, a swing arm, and a cutting machine; the base is fixedly connected to the operating table, and two vertical plates are spaced apart on the top wall of the base; two inclined plates distributed in an eight-shaped shape are provided on the bottom wall of the pressure cover, and the ends of the two inclined plates close to each other are respectively hinged to the ends of the two vertical plates; a cutting groove is provided on the pressure cover, and the cutting groove is located between the two inclined plates, and the extension direction is perpendicular to the hinge axis of the inclined plates; one end of the swing arm is hinged to the pressure cover along the hinge axis of the inclined plates, and the other end is used for the operator to hold and swing up and down; the cutting machine is arranged on the swing arm, and the cutting blade of the cutting machine corresponds to the cutting groove up and down. The utility model provides a flexible material cutting device, which can be used for cutting flexible materials of different thicknesses, and has simple and labor-saving operation and high cutting efficiency.

[0004] At present, when cutting flexible materials such as gauze, non-woven fabrics, and paper, the commonly used cutting devices mostly adopt the method of upper and lower pressure cutting or rotary cutting. The existing pressure cutting structure cuts when the cutting blade moves with the cutting blade holder to engage with the fixed blade. When the cutting device is in use, it is easy to cause the blade to get stuck, difficult to cut, and uneven cutting. Rotary cutting will produce more debris and pollute the processing environment.

[0005] Therefore, we propose a flexible material cutting device to solve the existing problems. Utility Model Content

[0007] To achieve the above purpose, the utility model provides the following technical solution: a flexible material cutting device, comprising:

[0009] Preferably, the

[0010] A hydraulic cylinder is mounted on the upper surface of the frame by bolts;

[0011] The output end of the hydraulic cylinder passes through the frame and is fixed to the upper surface of the mounting head by bolts.

[0022] During use, the flexible material cutting device of the utility model can roll up the flexible material to be cut into a bundle and pass it through between the U-shaped knife and the chute;

[0023] At this time, the hydraulic cylinder works, thereby driving the U-shaped knife to move down in the notch. During the downward movement of the U-shaped knife, the pressure block is driven to move down first to contact the surface of the material. At this time, as the U-shaped knife continues to move down, the pressure block is hindered, so that the slide bar moves upward relative to the extension plate, and the spring is compressed and deformed. Under the elastic force of the deformation, the two pressure blocks can squeeze and position the materials on both sides of the U-shaped knife;

[0024] Then, as the U-shaped knife continues to move downward, the U-shaped knife and the notch engage with each other, thereby cutting the material in between. After the cutting is completed, the U-shaped knife moves upward, thereby driving the pressing block away from the material, so that the cut material can be removed;

[0025] The utility model improves the existing pressing and cutting method to perform cutting, thereby avoiding knife jamming, difficulty in cutting, uneven cutting and the like, and greatly reduces the generation of debris compared to rotary cutting. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Embodiment 1

[0035] A floor 1, a U-shaped knife 4, a chute 5, an extension plate 7, a mounting head 10 and a slide rod 13. The outer wall of the chute 5 is symmetrically provided with a support frame 3. The bottom end of the support frame 3 is fixed to the upper surface of the floor 1. A frame 8 is provided on the top of the support frame 3. A mounting head 10 is provided on the frame 8 for lifting. The lower surface of the mounting head 10 is provided with a U-shaped knife 4. A notch 11 adapted to the U-shaped knife 4 is opened on the chute 5. The U-shaped knife 4 is slidably arranged on the notch 11. Pressure blocks 6 are symmetrically and elastically provided on both sides of the mounting head 10.

[0036] Based on Example 1:

[0037] During use, the flexible material to be cut can be rolled into a bundle and passed between the U-shaped knife 4 and the chute 5;

[0038] At this time, the hydraulic cylinder 9 works, thereby driving the U-shaped knife 4 to move downward in the notch 11. During the downward movement of the U-shaped knife 4, the pressure block 6 is driven to move downward to contact the surface of the material. At this time, as the U-shaped knife 4 continues to move downward, the pressure block 6 is hindered, so that the slide bar 13 moves upward relative to the extension plate 7, and the spring 14 is compressed and deformed. Under the elastic force of the deformation, the two pressure blocks 6 can squeeze and position the material positions on both sides of the U-shaped knife 4;

[0039] Then, as the U-shaped knife 4 continues to move downward, the U-shaped knife 4 and the notch 11 engage with each other, thereby cutting the material therebetween. After the cutting is completed, the U-shaped knife 4 moves upward, thereby driving the pressing block 6 away from the material, so that the cut material can be removed;

[0040] The existing pressing and cutting method is improved to avoid knife jamming, difficulty in cutting, uneven cutting and the like, and compared with rotary cutting, the generation of debris is greatly reduced.

[0041] Embodiment 2

[0045] The design of the hydraulic cylinder 9 can provide power for the up and down movement of the U-shaped knife 4 and the pressing block 6.

[0051] A positioning cap 12 is threadedly mounted on the top end of the slide rod 13 , and the lower surface of the positioning cap 12 is pressed tightly against the upper surface of the extension plate 7 .

[0052] The hydraulic cylinder 9 works, thereby driving the U-shaped knife 4 to move downward in the notch 11. During the downward movement of the U-shaped knife 4, the pressure block 6 is driven to move downward to contact the surface of the material. At this time, as the U-shaped knife 4 continues to move downward, the pressure block 6 is hindered, so that the slide bar 13 moves upward relative to the extension plate 7, and the spring 14 is compressed and deformed. Under the elastic force of the deformation, the two pressure blocks 6 can squeeze and position the material positions on both sides of the U-shaped knife 4;

[0053] Then, as the U-shaped knife 4 continues to move downward, the U-shaped knife 4 and the notch 11 engage with each other, thereby cutting the material therebetween. After the cutting is completed, the U-shaped knife 4 moves upward, thereby driving the pressing block 6 away from the material, so that the cut material can be removed.
