Description

Technical Field

[0001] The utility model relates to the technical field of mask production, and more specifically, to a hot press for mask production. Background Art

[0002] A mask is a hygiene and epidemic prevention product, generally referring to a device worn over the nose and mouth to filter the air entering the nose and mouth, so as to block harmful gases, odors, droplets, viruses and other substances, and is made of materials such as gauze or paper. Masks have a certain filtering effect on the air entering the lungs. Wearing a mask is very useful during the epidemic of respiratory infectious diseases and when working in a polluted environment such as dust. Masks can be divided into air-filtering masks and air-supplied masks.

[0003] Currently, masks are common items in people's lives. For some masks, a metal nose clip is hot-pressed at the nose part, so that it can better fit the face during use, thereby enhancing the protection effect. However, during the process of hot-pressing the metal nose clip, most of the existing mask hot-presses are operated individually. Such an operation undoubtedly reduces the continuity of hot-pressing and affects the hot-pressing efficiency. Therefore, it is necessary to propose a hot press for mask production to solve the above problems. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a hot press for mask production, aiming to improve the problem that most of the existing mask hot-presses are operated individually, which undoubtedly reduces the continuity of hot-pressing and affects the hot-pressing efficiency.

A limiting groove 146 is formed on the hot pressing head 145. A protective cover 143 is installed on the mounting frame 141. Here, the cylinder 142 can push the hot pressing head 145 to move. At the same time, the limiting groove 146 can facilitate the positioning and placement of the metal nose clip strip. At the same time, the metal nose clip strip can be hot pressed onto the mask by using the hot pressing head 145.

[0029] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 6 , the rotation structure 200 includes an annular rotating plate 210, a stepping motor 240, and a transmission member 250. The annular rotating plate 210 is installed at the annular notch 121 through a connecting member 230. Limiting members 220 are circumferentially distributed on the top surface of the annular rotating plate 210. The stepping motor 240 is installed at the bottom of the support plate 130. The stepping motor 240 is in transmission connection with the annular rotating plate 210 through the transmission member 250.

[0030] The limiting member 220 includes a bracket 221 and a limiting die base 222. The bracket 221 is installed on the annular rotating plate 210, and the limiting die base 222 is installed on the bracket 221. Here, the limiting member 220 can facilitate the positioning and placement of the mask surface, so that the hot pressing operation can be carried out more accurately. The connecting member 230 includes a first annular plate 231 and a first ball 232. The first annular plate 231 is fixed inside the annular rotating plate 210, and the first balls 232 are installed on both sides of the first annular plate 231. The first balls 232 are in rolling connection inside the first annular groove 122; the first annular plate 231 is located inside the annular notch 121, and the first balls 232 are circumferentially distributed on the first annular plate 231. Here, the setting of the first balls 232 can make the annular rotating plate 210 more labor-saving when rotating.

[0031] The transmission member 250 includes a second annular plate 251, a gear ring 252 and a transmission wheel 253. The second annular plate 251 is fixed to the bottom of the annular rotating plate 210. A second ball 254 is installed at the bottom of the annular rotating plate 210.

Here, the transmission wheel 253 is a gear; the second balls 254 are circumferentially distributed at the bottom of the second annular plate 251, and the second balls 254 are in rolling connection inside the second annular groove 131. Here, by the operation of the stepping motor 240, under the action of the transmission member 250, the annular rotating plate 210 can be driven to rotate continuously by forty-five degrees, so that continuous hot pressing operations can be facilitated and the hot pressing efficiency can be improved.

[0032] Specifically, the working principle of the hot press for mask production: When in use, two people can cooperate to first place the mask face on the limiting die base 222 for positioning, and at the same time place the metal nose clip into the limiting groove 146. Then the air cylinder 142 works to drive the hot pressing head 145 and the metal nose clip to move together towards the limiting die base 222. The metal nose clip is fixed on the mask face by the extrusion between the hot pressing head 145 and the limiting die base 222. After completing one operation, the stepping motor 240 drives the annular rotating plate 210 to rotate by forty-five degrees under the action of the transmission member 250, so that another mask face rotates to the hot pressing position of the hot pressing head 145. While rotating, the metal nose clip is placed into the limiting groove 146 again for hot pressing operation. In this way, during the hot pressing time period, the hot-pressed mask face can be removed and a new mask face can be placed, which is beneficial to making more full use of the hot pressing time, improving the continuity of hot pressing and the hot pressing efficiency, and making it more convenient to use.
