Problems solved by technology

[0002] In the automatic production process of masks, it is necessary to cut the ear straps. The existing shearing mechanism mainly uses a multi-link mechanism as the transmission mechanism of the shearing power. For example, a three-dimensional mask cutting device disclosed in CN202021621473 adopts the above-mentioned The transmission chain of the advanced transmission mechanism is relatively long, and when it is used for a long time, the connecting rod mechanism is prone to wear, which will lead to unreliable shearing power transmission, resulting in unstable shearing process and prone to continuous shearing defects
[0003] Although, in CN202020554771, a scissors mechanism of a mask earband welding machine is disclosed, which discloses a structure using a guide groove, but it adopts a guide structure with a single chute, and its stroke is relatively long in the specific use process, and Occupies a large volume and cannot be well adapted to small earband welding machines

Embodiment 1

[0031] see Figure 1-2 , the mask earband cutting device based on the chute mechanism, which includes a vertical plate 1, the vertical plate 1 is fixedly installed on the frame of the mask machine through the vertical plate base, and the outer wall of the vertical plate 1 is equipped with a knife rest plate placed obliquely 5. A chute 11 is processed on the knife rest plate 5, and a sliding seat 22 is slidably fitted on the chute 11. The first scissor body 16 and the second scissor body 17 arranged crosswise are hinged on the sliding seat 22 through a pin shaft 21; The afterbody of a scissors body 16 and the second scissors body 17 cooperates with the roller guide mechanism, and is used to realize the closing and separating action of the scissors head; This shearing device adopts the chute mechanism as the transmission guide of the shearing power of the scissors, replacing the traditional multi-link mechanism, thereby ensuring the stability of the transmission and the reliabil...

Embodiment 2

[0040] The using method of the mask ear strap cutting device based on the chute mechanism comprises the following steps:

[0041] Step 1: Fix the whole device on the frame of the mask machine, and adjust the installation position of the whole device according to the position where the ear strap needs to be cut;

[0042]Step 2: Adjust the installation height and installation angle of the tool holder plate 5 on the installation groove 7, and ensure that the first scissors body 16 and the second scissors body 17 are just matched with the ear straps of the mask machine during the stretching and cutting process, and achieve its shearing;

[0043] Step 3, start the mask machine, and pull the ear strap line through the traction mechanism. During the traction process, start the sliding device, drive the piston rod 9 through the cylinder 4, and drive the sliding seat 22 through the piston rod 9, and the sliding seat 22 moves along the The chute 11 slides;

[0044] Step four, the slid...

Abstract

The invention provides a mask ear band shearing device based on a sliding groove mechanism and a using method. The mask ear band shearing device comprises a vertical plate, the vertical plate is fixedly installed on a rack of a mask machine through a vertical plate base, and an inclined knife rest plate is installed on the outer side wall of the vertical plate. A sliding groove is machined in the knife rest plate, a sliding base is in sliding fit with the sliding groove, and a first scissor body and a second scissor body which are arranged in a crossed mode are hinged to the sliding base through a pin shaft. The tail parts of the first scissor body and the second scissor body are matched with a roller guide mechanism and are used for realizing the closing and separating actions of the scissor heads. The sliding base is connected with a sliding device used for driving the sliding base to slide along a sliding groove.

Description

technical field [0001] The invention belongs to the technical field of mask automatic production, in particular to a mask ear strap cutting device based on a chute mechanism and a use method. Background technique [0002] In the automatic production process of masks, it is necessary to cut the ear straps. The existing shearing mechanism mainly uses a multi-link mechanism as the transmission mechanism of the shearing power. For example, a three-dimensional mask cutting device disclosed in CN202021621473 adopts the above-mentioned The transmission chain of the traditional transmission mechanism is relatively long, and when it is used for a long time, the connecting rod mechanism is prone to wear and tear, which leads to unreliable shearing power transmission, unstable shearing process, and prone to continuous shearing defects. [0003] Although, in CN202020554771, a scissors mechanism of a mask earband welding machine is disclosed, which discloses a structure using a guide gro...
