Description

Technical Field

[0001] The utility model belongs to a protective device, in particular to a protective device for preventing fingers from being rolled into between two round rollers in a round-to-round compounding / die-cutting device. Background Art

[0002] In general round-to-round compounding / die-cutting equipment, the upper and lower round rollers in the compounding / die-cutting seat rotate in opposite directions. The material to be processed passes through the gap between the two rollers. The interaction between the two rollers is used to complete the compounding or die-cutting of the material. Therefore, when new material is loaded onto the machine or material is cut off and connected, it is necessary to manually feed one end of the material between the two rotating round rollers. The fingers may be caught between the two rollers due to the operator's negligence, causing a strangulation accident. Summary of the invention

[0003] In order to reduce or even eliminate such finger twisting accidents caused by manual feeding, the utility model provides a fixed protective device for preventing finger twisting applied to a round-to-round compounding / die-cutting seat. This device can block human fingers outside the gap between two round pressing rollers without affecting feeding, acting as a partition, directly and physically eliminating the possibility of injury accidents caused by unsafe human behavior factors during manual feeding.

[0004] The technical solution adopted by the utility model to solve its technical problem is: for the convenience of description, the two round rollers of the compound / die-cutting seat are referred to as "large round rollers" below, and the mounting wall panel of the compound / die-cutting seat is referred to as "large wall panel". This protective device is mainly composed of two identical small round rollers and two identical small wall panels. The two ends of the two small round rollers are first fixedly installed on two opposite small wall panels, and then the small wall panel is fixedly installed on one side of the feeding direction of the large wall panel. Therefore, when feeding, the material needs to first pass between the two small round rollers and then pass between the two large round rollers.

[0005] The above-mentioned fixed protective device for preventing finger twisting applied to the round-to-round compounding / die-cutting seat has a very small gap between the two small round rollers, which is just enough to allow the material to pass through without damaging the material.

[0006] The above-mentioned fixed protective device for preventing finger twisting applied to the round-to-round compounding / die-cutting seat, the two small round rollers are installed up and down, and the center line of their gap is at the same height as the center line of the gap of the two large round rollers.

[0007] In the above-mentioned fixed protective device for preventing fingers from twisting and twisting applied to a round-to-round compounding / die-cutting seat, the installation positions of the two small round rollers are as close as possible to the large round roller, but cannot be tangent to it.

[0008] The above-mentioned fixed protective device for preventing finger twisting applied to the round-to-round compounding / die-cutting seat, the two small round rollers are core-wrapped rollers, the shaft core extends from both ends, and the total shaft core length = the distance between the two large wall panels.

[0009] The beneficial effect of the utility model is that by adding the above protection device on the feeding side of the compound / die-cutting seat, it can effectively prevent the operator's fingers from being caught in the gap between the round rollers and causing crushing injuries when manually feeding.

[0012] In the figure, 1. small round roller, 2. small wall panel, 3. shaft core, 4. shaft core hole, 5. wall panel screw hole, 6. side screw hole, 7. large round roller, 8. large wall panel. DETAILED DESCRIPTION

[0013] A fixing protective device for preventing finger twisting applied to a round pressing compound / die cutting seat comprises two small round rollers 1 and two small wall panels 2. The two small wall panels 2 are respectively provided with two shaft core holes 4 of the same size as the shaft core of the small round roller and two wall panel screw holes 5 for fixing with a large wall panel 8 at mirror-corresponding positions. One side surface of the small wall panel 2 is a plane. There are two side screw holes 6 penetrating into the shaft core holes 4 at the same height as the two shaft core holes 4 on the front side. The shaft cores 3 at both ends of the small round roller 1 are respectively inserted into the shaft core holes 4 of the small wall panel 2 without exposing the wall panel. Then, screws are screwed into the side screw holes 6 to connect and fix the small round roller 1 to the small wall panel 2. Finally, the above installed device is knocked into a suitable position between the large wall panels 8 with a tool, and screwed into the wall panel screw holes 5 of the small wall panel 2 to fix it to the large wall panel 8 (screw holes are reserved in advance at the corresponding positions on the large wall panel 8).

[0014] When feeding manually, the material is fed into the gap between the small round rollers 1, and the material comes out of the gap between the small round rollers 1 and then enters the gap between the large round rollers 7.

[0015] The above are only preferred feasible embodiments of the present invention, and the protection scope of the present invention is not limited thereto. Various modifications or applications made according to the above embodiments are within the protection scope of this technical solution.
