Problems solved by technology

[0003] In the current mask production line, after the ear wire is cut, when the ear wire is clamped and swung to the mask welding point position on the mask assembly line, the clamp needs to be moved down vertically, clamped and lifted, and then moved down again at the welding point for welding. When returning It is also necessary to lift the clamp and swing it back. If you do not lift the clamp, it will conflict with the unintercepted ear wire when swinging back. In one swing cycle, there are 4 vertical movements, which take up more than half of the time, which obviously affects Increased production efficiency and reduced production capacity

Embodiment 1

[0038] like figure 1 , 2 , the driving rod 3 is perpendicular to the movable clamp 10, and the driving rod 3 makes a reciprocating rotation at a set angle to complete the action of clamping and releasing the reset. In the releasing reset position, the lower end of the movable clamp end 9 is not lower than the lower end of the fixed clamp end 8 , and the movable clip end 9 has reached the reset position before crossing the ear wire, so that the movable clip end 9 will not conflict with the stretched ear wire to be intercepted during the cycloidal process of the side clamp device; The bottom of the remaining clamp end 8 is assembled at the lower end. The driver 4 can be directly formed by a stepping motor or a servo motor, or can be formed by a link mechanism driven by a DC motor to reciprocate.

[0039] from figure 1 , 2 It can be seen from the first embodiment that the movable clip 10 is not connected to the fixed base 2, but only connected to the output shaft of the drive...

Embodiment 2

[0044] like image 3 , 4 , the swing arm 11 of the movable clamp 10 is provided with a swing pin 20 and a guide groove 18, the swing pin 20 is perpendicular to the movement plane of the movable clamp and is pivotally connected with the movable clamp 10 body, and the movement of the driving rod 3 and the movable clamp The planes are parallel, and the driver 4 is arranged on one side of the swing direction of the swing arm 11 . In fact, the fixed base 2 is integrally provided with a moving tool plate 17 on the side, the driver 4 is fixed to the moving tool plate 17, and the driving rod 3 performs telescopic movement or lateral swing. The driving rod 3 can be a cylinder or an electromagnet, or the motor can The driving rod 3 is driven to swing back and forth by the link mechanism. The outer end of the driver 4 is connected with the swing pin 20, and one end of the push-pull swing arm 11 moves back and forth when the drive rod 3 moves laterally.

[0045] The guide groove 18 is ...

Abstract

A mask production thread swinging and side clamping device is used for clamping a cut ear thread to a mask ear thread welding position on a mask production line in a reciprocating mode and comprises adriver fixed to a fixed base and a movable clamp. The movable clamp is used for clamping and releasing the ear thread from one transverse side of the ear thread and is provided with a movable clamp end and a swing arm, and the driver drives a rotating shaft to drive one end of the movable clamp to swing back and forth. By means of the mask production thread swinging and side clamping device, earthread swinging and conveying welding equipment on the mask production line is improved, an original structure is replaced with a simpler structure and a smaller size, the frequent vertical movement process of a clamp in the clamping and swinging and conveying process is omitted, meanwhile, collision to uncut ear threads due to the movement of the equipment is not hindered, accordingly, the swinging, conveying and welding efficiency is improved by one or more times, the overall productivity is improved by 20% or above, and a clamping device is simpler and easier to maintain.

Description

technical field [0001] The invention relates to production equipment, in particular to a cycloid side clamping device for mask production. Background technique [0002] When the epidemic spreads in a large area, the masks that are in short supply become strategic materials. In emergency situations, the production capacity of masks becomes an important factor. How to use the existing production line to quickly transform at a low cost and significantly improve production efficiency is of positive significance to the mask industry at this stage and absolutely in the future. [0003] In the current mask production line, after the ear wire is cut, when the ear wire is clamped and swung to the mask welding point position on the mask assembly line, the clamp needs to be moved down vertically, clamped and lifted, and then moved down again at the welding point for welding. When returning It is also necessary to lift the clamp and swing it back. If you do not lift the clamp, it will ...
