Description

Technical Field

[0001] The utility model relates to the technical field of knee pad production, in particular to a cutting device for knee pad production. Background Art

[0002] The knee is an extremely important part in sports, but it is also a relatively fragile part that is easily injured. It is also extremely painful when injured and recovers slowly. Some people even experience dull pain when it rains or is cloudy. The thick felt "knee pads" that can be bought in almost all sporting goods stores can reduce and avoid injuries to a certain extent. They can also keep out the cold when used in winter and they are not expensive. We are not recommending "knee pads" as a necessity here, but it is a fact that they are widely used in all sports activities.

[0003] When knee pads are produced, the materials used need to be cut. Most of the existing cutting devices are not convenient for flattening the materials when used, resulting in the cut surface being easily offset when the materials are cut. At the same time, it is not convenient to press the cutting position when the materials are cut, which easily leads to an uneven cutting surface and affects the use of the materials. Therefore, we propose a cutting device for the production of knee pads. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a cutting device for the production of knee pads, which is equipped with a flattening component.

By setting a pressing component, under the action of a pressing rod, the material can be pressed on both sides of the cutting position to maintain the stability of the material during cutting and ensure the neatness of the cut surface. The utility model solves the problem that when the knee pads are produced, the materials used for the cutting need to be cut. When the existing cutting devices are used, it is mostly inconvenient to flatten the materials, resulting in the easy deviation of the cut surface position when the materials are cut.

[0028] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a cutting device for producing knee pads, including an operating table 1, and the upper part of the operating table 1 includes:

[0029] A leveling component 2, the leveling component 2 comprises a leveling shell 21, two leveling rollers 22 are arranged inside the leveling shell 21, and the leveling rollers 22 are arranged on the left and right sides of the leveling shell 21;

[0030] The clamping assembly 3 is provided with two groups. The clamping assembly 3 includes a clamping rod 31.

The upper ends of the plurality of connecting rods 32 all penetrate the upper side of the inner wall of the leveling shell 21 to the upper side thereof. The upper ends of the plurality of connecting rods 32 are fixedly connected to the limiting blocks 33. The plurality of limiting blocks 33 are all arranged on the upper side of the leveling shell 21. A clamping spring 34 is sleeved on the upper side of the rod wall of the connecting rod 32. The rod walls of the plurality of connecting rods 32 are slidably connected to a cutting frame 35.

[0031] A cutting assembly 36 is arranged below the cutting frame 35 . The pressing assembly 3 includes a mounting frame 361 . A cutting blade 362 is fixedly connected to the inner wall of the mounting frame 361 by bolts. A blade groove 363 is provided on the upper surface of the leveling shell 21 .

[0032] The front and rear sides of the inner wall of the operating table 1 are fixedly connected with first electric cylinders 24 , the output ends of the two first electric cylinders 24 are fixedly connected with connecting plates 25 , and the opposite sides of the two connecting plates 25 are fixedly connected with the front and rear sides of the leveling shell 21 .

[0033] The upper and lower ends of multiple compression springs 34 are respectively fixedly connected to the bottom of the limit block 33 and the top of the cutting frame 35, and the front and rear sides of the leveling shell 21 are fixedly connected with connecting frames 26. The tops of the two connecting frames 26 are fixedly connected with second electric cylinders 27. The output ends of the two second electric cylinders 27 are respectively fixedly connected to the front and rear sides of the cutting frame 35, and the output ends of the two second electric cylinders 27 pass through the top of the connecting frame 26 to the inside thereof.

[0034] A first movable assembly 37 is provided inside the cutting frame 35, and the first movable assembly 37 includes a first movable block 371. The surface of the first movable block 371 is slidably connected to the inner wall of the cutting frame 35. The inner wall of the first movable block 371 is threadedly connected with a one-way screw rod 372. The rear end of the one-way screw rod 372 is fixedly connected with a first motor 373.

[0036] During use, when the material needs to be cut, the first electric cylinder 24 drives the connecting plate 25 on the leveling shell 21 to move downward, so that the leveling roller 22 in the leveling shell 21 can be close to the upper surface of the material. Through the movement of the leveling roller 22, the fabric is pushed to both sides to spread out, so that the material remains flat when cutting;

[0037] When the material is cut, the cutting frame 35 is driven to move downward by the second electric cylinder 27 on the connecting frame 26. When the cutting frame 35 moves, the cutting frame 35 drives the pressing rod 31 in the leveling shell 21 to move downward through the connecting rod 32, so that the pressing rod 31 can press the two sides of the position to be cut. When the pressing rod 31 continues to move downward, the pressing spring 34 between the limit block 33 and the cutting frame 35 is stretched.
