Description

Technical Field

[0001] The utility model relates to the technical field of mask processing, in particular to an electrostatic elimination device. Background Art

[0002] A mask is a hygiene and epidemic prevention product, generally referring to a device worn over the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances. During the processing of masks, a mask machine is required. A mask machine is a device that processes non-woven fabrics into various types of masks. The processes include: feeding, conveying, shaping, folding, slicing, welding, punching and outputting, etc. When processing, it is necessary to convey the mask cloth. During the conveying process, the mask cloth will rub against the conveying device to generate static electricity. Static electricity can easily cause dust to adhere to the mask piece. If the static electricity is not eliminated, the continuous adsorption of dust by the mask piece will contaminate the mask piece, resulting in a reduction in the yield of mask production.

[0003] After retrieval, the patent with the Chinese patent application number 202021688643.7 discloses a full-automatic flat mask machine, including a machine case. A flat mask body manufacturing machine is arranged on the left side of the upper end of the machine case. The flat mask body manufacturing machine includes a motor inside, and the motor is arranged at the bottom end of the left side inside a fixed frame. The driving end of the motor is fixedly connected with a hinge group. A first connecting rod is fixedly connected inside the sprocket at the top end of the hinge group. A first bevel gear is arranged on the right side of the first connecting rod. The first bevel gear is meshed and connected with a second bevel gear. The bottom end of the front end of the second bevel gear is rotatably connected to one end of a fixed rod. A water tank is arranged on the left side of the machine case. A water pump is arranged at the top end inside the water tank. The above-mentioned full-automatic flat mask machine in the patent has the following deficiencies: When processing masks, it is necessary to convey the mask cloth. Friction will occur during the conveying process, resulting in the generation of static electricity. After the static electricity is generated, dust will be adsorbed onto the mask cloth. The device is not provided with an electrostatic elimination device and cannot eliminate the static electricity of the mask cloth, thereby causing the mask cloth to be contaminated by adsorbed dust and affecting the yield of mask production.
