Description

Technical Field

[0001] This invention relates to the field of sponge production technology, specifically to a device and method for cutting rough edges of foamed sponges. Background Technology

[0002] Sponge is a type of polyurethane foam, belonging to the category of soft polyurethane foam. Due to its porous honeycomb structure, it has excellent softness, elasticity, water absorption, and water resistance, and is widely used in industries such as sofas, mattresses, clothing, and soft packaging.

[0003] Existing foamed sponges are cut into segments, resulting in rough edges at the cut points. These rough edges affect the sales of the sponge segments. When cutting existing sponge segments with rough edges, the softness of the sponge causes deformation at the cut points, leading to incomplete cutting. At the same time, the cutting process generates sponge debris, which is difficult to collect. Furthermore, if the sponge is cut at an angle, it will cause dimensional deviations in the cut areas, affecting the quality of the foamed sponge. Summary of the Invention

[0004] To address these issues, the present invention provides a foam sponge burr cutting device and method, which solves the problems of insufficient cutting due to the softness of the sponge, the generation of sponge debris during cutting, the dimensional deviation of the cut area, and the impact on the quality of the foam sponge.

[0013] Preferably, the absorbent housing has two openings at the top, and each of the two openings has a side opening on one side. A baffle is fixedly installed inside the absorbent housing.

[0014] A method for cutting rough edges on foamed sponges, comprising the following specific steps:

[0015] S1. Place the sponge block body into the support frame, start the first motor, the first motor drives the transmission shaft to rotate, the transmission shaft drives the synchronous pulley to rotate, the synchronous pulley drives the synchronous belt to rotate, the synchronous belt drives the support frame to rotate, the support frame drives the sponge block body to move downward. During the movement, the pulley contacts the baffle, the pulley pushes the connecting plate and the positioning plate to move, the positioning plate drives the square rod to move, the spring outside the square rod is compressed, the two positioning plates move closer to each other and position the sponge block body. After the pulley and the baffle are no longer in contact, the spring rebounds and pushes the positioning plate to move, and the positioning mechanism stops moving.

[0016] S2. Start the first electric push rod, which pushes the absorbent housing to move. The absorbent housing moves to the bottom of the support frame. Start the second electric push rod, which moves the block down. The block moves the pressure plate down. The pressure plate compresses the sponge block body. Start the second motor, which drives the lead screw to rotate. The lead screw moves the slider, which moves the fixing plate. The fixing plate moves the cutter, which cuts the rough edges on the side of the sponge block body.

[0017] S3. Start the third motor. The third motor drives the fan blades to rotate. The fan blades generate suction, which sucks the debris into the recycling shell through the opening at the top of the absorption shell for centralized collection.

[0018] The embodiments of the present invention have the following advantages:

[0019] 1. The support frame drives the sponge block body to move downward. During the movement, the pulley contacts the baffle. The pulley pushes the connecting plate and the positioning plate to move. The positioning plate drives the square rod to move. The spring outside the square rod is compressed. The two positioning plates move closer to each other and position the sponge block body to prevent the sponge from being skewed during cutting, avoid dimensional deviations in the cut part of the sponge, and improve the quality of the foamed sponge.

[0020] 2. The block moves the pressure plate downward, compressing the sponge block. The slider moves the fixing plate, which in turn moves the cutter. The cutter cuts the rough edges on the side of the sponge block. The fan blades generate suction, drawing the debris into the recycling shell through the opening at the top of the absorption shell for centralized collection. This prevents the sponge from deforming easily when cut due to its softness, ensuring thorough cutting and easy recycling of debris for convenient cleaning. Attached Figure Description
