Description

Technical Field

[0001] The utility model relates to the technical field of EVA foam material slitting, in particular to an EVA foam material slitting device. Background Art

[0002] Foaming materials are commonly used materials that produce bubbles and form porous substances. Structurally, foaming materials are divided into soft foaming materials and structural foam materials. Soft foaming materials are made from raw materials such as plastics (PE, EVA, etc.) and rubbers (SBR, CR, etc.), along with auxiliary materials such as catalysts, foam stabilizers, and foaming agents. Through physical foaming or crosslinking foaming, a large number of fine bubbles appear in the plastics and rubbers, increasing the volume and reducing the density. Soft foaming materials are light in weight and good in softness, and have functions such as buffering, sound absorption, shock absorption, heat preservation, and filtration. They are widely used in industries such as electronics, household appliances, automobiles, and sports and leisure.

[0003] During the production process of EVA foam materials, slitting operations need to be carried out on EVA foam materials. Most of the existing slitting operations on EVA foam materials do not have the function of limiting and fixing the EVA foam materials. Workers need to hold the EVA foam materials by hand. It is very easy for the EVA foam materials to shake during slitting, resulting in a poor slitting effect, which is not conducive to the use of workers. For this reason, we have proposed an EVA foam material slitting device. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an EVA foam material slitting device to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A fixed frame is fixedly connected to the top of the base. The fixed frame is in the shape of an "n". An observation window is opened on one side of the fixed frame. A slitting component is arranged inside the fixed frame. Two symmetrically distributed motors are arranged on the top of the fixed frame. The output end of the motor is fixedly connected to a rotating shaft. The rotating shaft extends into the fixed frame. A transmission component is arranged on the outside of the rotating shaft. A sliding component is arranged on the inner wall top of the fixed frame. A clamping component is arranged inside the fixed frame.

Through the above structures provided, it is convenient for the staff to cut the EVA foam materials during the production process of EVA foam materials.

The first telescopic sleeves 7 extend into the fixing frame 3. A first telescopic rod 8 is slidably connected inside the first telescopic sleeve 7. The first telescopic rod 8 is fixedly connected to the top of the cutting knife 6. When the cutting knife 6 moves, it drives the first telescopic rod 8 to slide inside the first telescopic sleeve 7, so that the cutting knife 6 can move more stably.

The motor 10 is fixedly installed on the support frame 9. By arranging the support frame 9, the phenomenon that the motor 10 idles during operation can be avoided. The output end of the motor 10 is fixedly connected to a rotating shaft 11. The rotating shaft 11 extends into the fixing frame 3. A transmission component is arranged outside the rotating shaft 11. The transmission component includes a gear 12 fixedly connected to the bottom of the rotating shaft 11. The gear 12 is meshed with two racks 16. By arranging the transmission component, the two racks 16 can move towards each other.

[0022] Specifically, a sliding component is provided at the top of the inner wall of the fixing frame 3. The sliding component includes four symmetrically distributed slide rails 13 fixedly connected to the top of the inner wall of the fixing frame 3. A slide table 14 is slidably connected to the outside of each of the four slide rails 13. Two symmetrically distributed connecting rods 15 are fixedly connected to the bottom of the slide table 14. The bottom of the two connecting rods 15 is fixedly connected to the same rack 16.
