Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roll material die cutting dust removal, in particular to a roll material die cutting dust removal system and a roll material die cutting device. BACKGROUND

[0002] In the process of roll material product die cutting on a production line, some dust will inevitably be generated due to friction or cutting. If the dust cannot be collected and removed in time and effectively, it may affect the appearance and even the performance of the die-cut product. In addition, the dust may also affect the service life of the die cutting tool.

[0003] Currently, there are two types of roll material die cutting online dust removal methods, namely contact type dust removal and non-contact type dust removal. In the new material processing industry, most people will choose a contact type dust removal system, which relies on a dust sticking roller to capture dust, and then transfers the captured dust to a sticky roller.

[0004] Among them, the structure of the contact type dust removal system is relatively easy to install, but it needs to purchase a sticky paper roll consumable. Moreover, when the dust on the sticky paper roll reaches a certain amount, it needs to be replaced in time. If it is not replaced, the dust removal effect will be poor. For example, during the dust removal process, the roller with the sticky paper roll always sticks dust at the same position. If the sticky paper roll is not replaced in time, the dust removal effect at this position will be affected. However, replacing the sticky paper roll needs to be done manually in the state of equipment downtime, which reduces the processing efficiency and increases the labor cost. In addition, the sticky paper roll cannot remove the dust generated by the friction between the structure for limiting and clamping and the roll material, so manual cleaning is needed in the state of equipment downtime, which further reduces the processing efficiency and increases the labor cost. Content of the utility model

[0005] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application proposes a roll material die cutting dust removal system, which can remove dust in real time during roll material die cutting.

The negative pressure suction mechanism is arranged on the rack and is used to suck and remove the dust on the surface of the conveyed roll material.

[0008] According to the roll material die cutting dust removal system, the first brush body abuts against the upper surface of the conveyed roll material and moves relative to the conveyed roll material, so that the dust adhered to the upper surface of the conveyed roll material is separated from the conveyed roll material. Meanwhile, the second brush body abuts against the lower surface of the conveyed roll material and moves relative to the conveyed roll material, so that the dust adhered to the lower surface of the conveyed roll material is separated from the conveyed roll material. The negative pressure suction mechanism is used to suction the dust separated by the brush body assembly. Compared with the method of using adhesive paper to remove dust, the roll material die cutting dust removal system can remove dust in real time during the roll material die cutting process, without the need to manually replace the adhesive paper in the state of equipment shutdown on a regular basis, and without the need to manually clean the dust that cannot be removed by the adhesive paper in the state of equipment shutdown on a regular basis. Therefore, the roll material die cutting dust removal system can reduce the consumption of materials, reduce the number of equipment shutdowns and reduce manual operation, thereby improving the processing efficiency and reducing the labor cost.
