Description

Technical Field

[0001] The utility model relates to the technical field of foam production, in particular to a production and slitting device for electronic adhesive foam. Background Art

[0002] Adhesive foam primarily consists of a foam base and an adhesive layer. The foam base is typically made from materials such as polyurethane (PU), polyethylene (PE), and polypropylene (PP). These foam materials contain numerous tiny pores, which give the foam excellent elasticity, cushioning, and thermal insulation properties. The adhesive layer is typically pressure-sensitive adhesive, which becomes sticky when subjected to slight pressure, making it easy to adhere to various surfaces.

[0003] Existing Chinese patent application CN218428838U discloses a die-cutting mold for bonding foam for electronic products. The mold comprises a foam cutting table with a rectangular array of upright posts fixedly inserted on its surface. A top plate is fixed between the tops of the upright posts. The top plate has a through-slot and an inner groove communicating with the through-slot. An adjustment assembly is removably mounted on the sidewalls of the top plate, extending into the through-slot and the inner groove. A hydraulic lift rod is inserted through the surface of the adjustment assembly. The telescopic end of the hydraulic lift rod extends into a fixed sleeve, and a side insert is inserted into the outer periphery of the fixed sleeve, which abuts the end of the telescopic end of the hydraulic lift rod. A cutter mounting frame is fixedly mounted on the bottom of the fixed sleeve, and the bottom of the cutter mounting frame has a dovetail groove. This allows the foam to be compacted before cutting, preventing outward bending of the foam and resulting in uneven cut surfaces. This improves die-cutting quality and increases die-cutting flexibility.

[0004] However, the above patent can only cut the foam in a single direction and horizontal position during the foam cutting process, but some electronic products are polygonal or have beveled edges, and the cutting direction cannot be adjusted according to the needs of the electronic products, which affects the subsequent adaptation of the foam to the electronic products.

[0005] Therefore, it is necessary to provide a kind of electronic adhesive foam production and slitting equipment for use. Utility Model Content

[0010] According to a further technical solution, the slitting tool holder includes a mounting block and a slitting tool, wherein the mounting block is located at the bottom of the rotating shaft, and the slitting tool is connected to the mounting block.

[0011] According to a further technical solution, the mounting block is provided with four cutting and pressing members, and the four cutting and pressing members are located at the four corners of the mounting block.

[0026] During use, the adhesive foam is placed horizontally on the automatic conveyor belt 11, and the automatic conveyor belt 11 can drive the position of the adhesive foam to move forward so that the subsequent processing of the slitting structure 2 can drive the slitting knife holder 3 to move downward to cut the adhesive foam. After the slitting is completed, the slitting adhesive foam can be transported outward through the automatic conveyor belt 11, and in the process of slitting, the angular position of the slitting knife holder 3 can be driven to rotate by the processing rotating structure 4. According to the needs of slitting the adhesive foam, adhesive foams of different shapes at the cutting point and adhesive foams with beveled edges at the cutting point can be cut to meet the needs of different types of electronic products.

[0027] In this embodiment, referring to Figure 3 As shown, the processing and slitting structure 2 includes a slitting cylinder 21, a mounting frame 22 and two sliding rods 23. The slitting cylinder 21 is vertically arranged on the top of the support frame 12, and the mounting frame 22 is connected to the telescopic end of the slitting cylinder 21. The two sliding rods 23 are symmetrically arranged on the top of the mounting frame 22, and the sliding rods 23 are slidably matched with the support frame 12.

[0028] During cutting, the cutting cylinder 21 drives the mounting frame 22 to slide on the support frame 12 through the two slide rods 23, thereby driving the cutting knife frame 3 to move downward to cut the adhesive foam. During cutting, the adhesive foam can be cut horizontally and the adhesive foam can be cut at an angle as needed to meet the needs of different types of electronic products.

[0029] In this embodiment, referring to Figure 4As shown, the processing rotating structure 4 includes a rotating motor 41, a first gear 42, a second gear 43 and a rotating shaft 44.

While pressing, the pressing rod 53 slides on the slider 52 and can be adjusted according to the thickness of the adhesive foam. The setting of the compression spring 57 ensures that the position of the pressing plate 54 is reset after a piece of adhesive foam is cut.

[0034] The slider 52 can move horizontally in the slide frame 51 according to the size of the adhesive foam, thereby adjusting the distance between the two adjacent pressing plates 54 to meet the needs of slitting and fixing adhesive foams of different sizes. After the slider 52 is fixed in the position in the slide frame 51, the screw 56 is inserted into the corresponding plug hole 55 to achieve fixation between the slider 52 and the slide frame 51.
