Description

Technical Field

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

[0002] In our daily life, sponges are very common. They are porous materials with good water absorption and can be used to clean items. They are usually formed by mixing foaming resin, foaming aid and adhesive resin together. The foaming machine is a device for making sponges. The air is introduced into the foaming agent aqueous solution through the stirring action of the foaming machine to disperse it evenly, so that the liquid phase foaming agent and the introduced air in the gas phase have as large a contact surface as possible and react to form bubbles to form a sponge. In the process of sponge cutting, in order to prevent it from moving, it is often necessary to clamp the structure to limit it;

[0003] However, the existing compression structure still has the following technical problems when used:

[0004] Since the sponge material is relatively soft, it will deform greatly when squeezed. The current clamping structure often limits the sponge from the side. However, when cutting, as the cutting knife contacts the sponge, the sponge will be severely deformed, resulting in an uneven cut. Moreover, when processed under the limiting effect of the current clamping structure, the thicker the sponge, the more uneven the cut will be during the cutting process.

[0005] Therefore, a sponge pressing structure of a sponge cutting machine is proposed to solve the above-mentioned problems. Utility Model Content

After the sponge 3 is initially limited by the limiting mechanism, the sponge 3 is longitudinally squeezed by the pressing plate 7 until it is difficult to deform, and the sponge 3 is cut by moving the blade 13 downward, which effectively avoids deformation due to the contact of the blade 13 during the cutting process, facilitates cutting, and increases the neatness of the cutting mouth.

[0025] The position adjustment mechanism includes a chassis 14, which is fixedly connected to the left side wall of the base plate 1. A motor 15 is fixedly arranged inside the chassis 14, and a transmission rod 16 is fixedly arranged at the output end of the motor 15. The right end of the transmission rod 16 is rotatably connected to the left side wall of the base plate 1, and a symmetrical first pulley is sleeved on the rod wall of the transmission rod 16. A screw rod 17 is arranged inside the two slide grooves for transverse rotation through bearings. The left ends of the two screw rods 17 extend to the interior of the chassis 14 and are sleeved with a second pulley. The two first pulleys are rotatably connected to the two second pulleys through belts. The rod walls of the two screw rods 17 are threadedly provided with adjustment blocks 18, and the lower side wall of the bracket 2 is fixedly connected to the upper side walls of the two adjustment blocks 18.

When the sponge 3 is deformed to a certain extent due to squeezing, the second electric push rod 11 is started, and the second electric push rod 11 drives the knife seat 12 and the blade 13 at the lower end to move downward to cut the sponge 3. During the cutting process, because the sponge 3 has been squeezed to the maximum deformation at this time, the sponge 3 is relatively thin during the cutting process, and the cutting mouth is relatively neat, thereby improving the processing quality.
