Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting devices, in particular to a foam mesh double-sided adhesive combined die-cutting device. Background Art

[0002] Foam mesh double-sided tape is a high-performance adhesive material widely used in the electronics, automotive, construction, packaging and other industries. It has excellent adhesion, weather resistance, aging resistance, and flexibility, and can adapt to various complex working environments. In the electronics industry, in particular, foam mesh double-sided tape is often used to fix and seal components such as display screens, touch screens, keyboards, and speakers. Die-cutting is the process of cutting foam mesh double-sided tape into specific shapes and sizes to meet different application requirements. Traditional die-cutting methods have problems such as low precision, low efficiency, and high scrap rates, making it difficult to meet the high-precision, high-efficiency, and high-quality requirements of modern industry. Therefore, it is particularly important to develop an efficient and precise foam mesh double-sided tape combination die-cutting device.

[0003] Low die-cutting precision will result in uneven product edges, affecting the appearance and function of the product. Due to low die-cutting precision, it may lead to material waste and increase production costs. Appearance defects such as burrs, tears or holes will affect the overall appearance of the product. Poor die-cutting quality may require more rework and repairs, thereby reducing production efficiency. Utility Model Content

Since the positioning is more accurate, the deviation in the die-cutting process is reduced, and the generation of waste due to position offset is reduced. The buffering effect of the spring can reduce the impact force of the mold during operation, reduce the wear rate of the mold, and thus extend the service life of the mold.

[0005] In order to achieve the above-mentioned purpose, a foam mesh double-sided tape combined die-cutting device is provided, comprising: a processing table, a middle mold is provided at the top of the processing table, and the characteristics are: a positioning groove is provided at the top of the middle mold, the inner bottom end of the positioning groove is in contact with a spring, the top of the spring is in contact with a limiting column, and the limiting column and the positioning groove are slidably connected, the top of the limiting column is in contact with a limiting ring, and the limiting ring and the inner ring of the positioning groove are fixedly connected, and the top of the limiting column is fixedly connected with a fixed column.

The top end of the limiting post 14 is fixedly connected to the fixing post 15, which is used to connect the upper mold 7 to ensure that the upper mold 7 can accurately act on the foam mesh double-sided tape when pressed down.

[0023] The top of the processing table 1 is fixedly connected to the lower mold 2, and the lower mold 2 cooperates with the upper mold 7 to complete the die-cutting work of the foam mesh double-sided tape. The four corners of the lower mold 2 are provided with slots 18. These slots 18 are designed to facilitate the placement and removal of materials. The inner bottom end of the slot 18 is provided with a lower limit block 3. The bottom of the lower limit block 3 contacts the processing table 1 to ensure that the position of the lower mold 2 is stable. The top of the lower limit block 3 is fixedly connected to the sliding rod 4. The sliding rod 4 can slide freely up and down in the middle mold 5 to ensure smooth relative movement between the upper mold 7 and the lower mold 2. The top of the sliding rod 4 is fixedly connected to the upper limit block 6. The function of the upper limit block 6 is to prevent the middle mold 5 from over- The degree of deformation rises, thereby protecting the safe operation of the equipment.
