Description

Technical Field

[0001] This utility model relates to a glass fiber mat production apparatus, and in particular to a glass fiber mat cutting device for preventing injury. Background Technology

[0002] In the final stage of production, fiberglass mat needs to be cut to the required width by a cutting device. However, in actual production, the cutting blade is positioned above the roller and the fiberglass mat. Due to excessive pressure between the cutting blade and the roller or the cutting blade reaching the end of its service life, it may break. After the cutting blade breaks, fragments will fly outward, posing a risk of injury to workers. Summary of the Invention

[0003] The purpose of this invention is to provide a highly safe fiberglass mat cutting device that prevents injury.

[0004] The technical solution to achieve the purpose of this utility model is as follows:

[0005] A fiberglass mat cutting device for preventing injury includes a pressure roller and a collection box located below the pressure roller. A cutter shaft is fixed inside the collection box, and a cutting blade is fixedly mounted on the cutter shaft. The upper end of the cutting blade is higher than the highest end of the collection box. A lifting cylinder is located below the collection box, and the lifting cylinder has a telescopic shaft. The upper end of the telescopic shaft is fixedly connected to the collection box.

[0006] With the above structure, the unwinding roller releases the fiberglass mat, which is then cut by the cutting blade and wound up by the rewinding roller. Since the cutting blade is located below the pressure roller, i.e. below the fiberglass mat, when the cutting blade is damaged and fragments are produced, the fragments cannot fly upwards due to the obstruction of the fiberglass mat above and eventually fall into the collection box below. After the cutting blade is damaged, the collection box and the cutting blade are lowered by the lifting cylinder, so that the cutting blade can be replaced and the fragments in the collection box can be cleaned. This utility model can greatly improve the safety of workers.

[0007] Preferably, to further enhance safety, baffles are fixed at both ends of the collection box, with the highest point of the baffles being higher than the highest point of the cutting blade.

[0008] Preferably, a scraper is provided inside the collection box to facilitate cleaning.

[0009] Preferably, in order to facilitate cleaning the collection box, the scraper is provided with protrusions at both ends, and the collection box is provided with strip-shaped grooves that cooperate with the protrusions. The protrusions are inserted into the strip-shaped grooves and slide in cooperation with the strip-shaped grooves. Attached Figure Description

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] Figure 2 This is a schematic diagram of the collection box structure of this utility model. Detailed Implementation

[0013] like Figure 1 and Figure 2 As shown, the fiberglass mat cutting device for preventing injury of this utility model includes a pressure roller 1 and a collection box 2 disposed below the pressure roller. A cutter shaft 3 is fixed inside the collection box, and a cutting blade 4 is fixedly mounted on the cutter shaft. The upper end of the cutting blade is higher than the highest end of the collection box. A lifting cylinder 5 is disposed below the collection box, and the lifting cylinder has a telescopic shaft 6. The upper end of the telescopic shaft is fixedly connected to the collection box. Baffles 7 are fixed at both ends of the collection box, and the highest point of the baffles is higher than the highest point of the cutting blade. A scraper 8 is disposed inside the collection box. Protrusions 9 are provided at both ends of the scraper, and a strip-shaped groove 10 that cooperates with the protrusions is provided inside the collection box. The protrusions are inserted into the strip-shaped grooves and slide in cooperation with the strip-shaped grooves.

[0014] With the above structure, the unwinding roller 11 releases the fiberglass mat, which is then cut by the cutting blade and wound up by the winding roller 12. Since the cutting blade is located below the pressure roller, that is, below the fiberglass mat, when the cutting blade is damaged and fragments are produced, the fragments cannot fly upwards due to the obstruction of the fiberglass mat above, and eventually fall into the collection box below. After the cutting blade is damaged, the collection box and the cutting blade are lowered by the lifting cylinder, so that the cutting blade can be replaced and the fragments in the collection box can be cleaned. This utility model can greatly improve the safety of workers.

[0015] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
