Technical Field

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

[0002] Rubber refers to a reversible, highly elastic polymer material that is highly elastic at room temperature. It can deform significantly under very small external forces and return to its original shape after the external forces are removed. Wear-resistant rubber lining is a material made of rubber. It is the abbreviation of the rubber material linings at both ends and the cylinder used in ball mills, also known as rubber lining or rubber inner lining.

[0003] In the field of rubber manufacturing, after the rubber is molded, it is necessary to cut the refined rubber in advance, so a rubber cutting machine is needed.

[0004] Currently, rubber cutting on the market usually requires an operator to hold the rubber and move it to the cutting blade on the cutting machine for cutting. However, during the cutting process, the operator may accidentally touch the blade, thereby increasing the risk of hand injury to the worker and reducing safety performance. It is also difficult to fix the rubber, resulting in deviations during cutting and reduced cutting quality. Utility Model Content

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Reference Figures 1-4 A rubber cutting machine includes a frame 1 with a notch 2 defined in its top surface, providing space for cutting operations. Mounting plates 3 are fixed to opposite sides of the frame 1. A screw 4 is rotatably connected to one mounting plate 3, a slide 5 slidably sleeved on the screw 4, a rotating rod 6 rotatably connected to the center of the slide 5, and a cutting blade 7 is fixedly sleeved in the center of the rotating rod 6. A rubber lining 8 is placed on the top surface of the frame 1.

[0037] A rubber cutting machine also includes a drive member, a guide member, and a clamping member. The drive member is used to drive the screw rod 4 and the rotating rod 6 to rotate, the guide member is used to control the sliding direction of the slide 5, and the clamping member is used to compress and fix the rubber lining 8. This design ensures the stability and accuracy of the slide 5 during movement. At the same time, the rotational connection between the rotating rod 6 and the limit seat 51 allows the rotating rod 6 to rotate simultaneously with the movement of the slide 5.

[0038] The driving component includes a first motor 41 and a second motor 61. The first motor 41 is fixed on the mounting plate 3, and the output end of the first motor 41 is fixedly connected to the screw rod 4. The second motor 61 is fixed on the slide 5, and the output end of the second motor 61 is fixedly connected to the rotating rod 6.

[0039] The guide includes a guide rod 52 fixed on the other side mounting plate 3 and a limiting seat 51 slidingly sleeved on the guide rod 52, and the rotating rod 6 is rotationally connected with the limiting seat 51. The guide ensures the stability and accuracy of the sliding seat 5 during movement, and guarantees the cutting quality.

[0040] The pressing member includes two support columns 9 fixed on the top surface of the rack 1, a concave plate 91 fixed on the support columns 9, a pneumatic cylinder 92 fixed on the concave plate 91, a piston rod 93 fixed on the output end of the pneumatic cylinder 92, and a rubber pressing wheel 94 fixed on the piston rod 93. The concave plate 91 has a cavity in the middle, and the piston rod 93 is arranged to extend and retract in the cavity of the concave plate 91.

[0041] The cutting knife 7 is arranged to slide in the recess 2. This design can limit the movement range of the cutting knife 7, avoiding possible deviations or errors during cutting. At the same time, the recess 2 can also protect the cutting knife 7 and the rack 1 from damage caused by debris or fragments generated during cutting.

[0042] The sliding seat 5 is hollow and has external threads that match the threads of the lead screw 4. The sliding seat 5 moves smoothly and accurately under the drive of the lead screw 4. When the lead screw 4 rotates, its threaded part interacts with the external threads in the sliding seat 5, pushing the sliding seat 5 to move along the lead screw 4. Due to the precise fit of the threads, the movement of the sliding seat 5 can be very smooth and accurate, achieving high-precision cutting operations and improving the precision and stability of the cutting machine. At the same time, the hollow design can also reduce the weight of the sliding seat 5, reduce energy consumption, and improve the overall performance of the equipment.

[0043] The utility model can be described by the following operation mode to explain its function principle:

[0044] During cutting, the rubber lining plate 8 to be cut is placed on the rack 1, the pneumatic cylinder 92 is started to drive the piston rod 93 to lower the rubber pressing wheel 94, the rubber pressing wheel 94 is attached to the surface of the rubber lining plate 8 to press and fix it, then the first motor 41 is started to drive the lead screw 4 to rotate in the mounting plate 3, when the lead screw 4 rotates, the sliding seat 5 with external threads matching the threads of the lead screw 4 is immediately driven to slide horizontally in the recess 2 through the threads, when the cutting knife 7 slides to contact the rubber lining plate 8, the second motor 61 is started to drive the rotating rod 6 to rotate in the sliding seat 5 and the limiting seat 51, the cutting knife 7 on the rotating rod 6 is immediately rotated to cut the rubber lining plate 8, so that the cutting is quickly completed, after cutting is completed, the first motor 41 and the second motor 61 are closed, the pressing member is released, and the cut rubber product is taken out to complete the cutting process.
