Description

Technical Field

[0001] The utility model relates to the technical field of mask machines, in particular to a sponge strip sticking device. Background Art

[0002] The sponge strip sticking device is used to stick the peeled sponge strips on the mask body to complete the production and processing of the mask. Among the existing patents, the Chinese patent document with application number 202220994047.4 discloses an automatic sponge sticking mechanism. In actual use, when the roll material passes through the peeling knife, the sponge strip is peeled off from the roll material belt. At this time, the peeled sponge strip is received by the sponge strip receiving block, and the first pneumatic rod and the second pneumatic rod are telescopically displaced to the designated position to wait for the sponge strip adsorption block to absorb it. Through the cooperation between the pneumatic rods, the sponge strip on the sponge strip receiving block is adsorbed by the sponge strip adsorption block. At this time, the discarded roll material belt after peeling is conveyed to the receiving reel for storage. When the roll material is used up, the production line is stopped, and the stripping sea of ​​the sponge strip peeling component 1 is removed. After the sponge strip is in the waiting area, the second motor starts working, and the transmission box drives the threaded rod to rotate, and then drives the slide to move to the working position on the mobile carrier through the threaded sleeve. At this time, the clamping claw cylinder works to drive the clamping block to clamp the sponge strip, and at the same time, the suction port on the adsorption pressure head sucks air to suck the sponge strip. The second motor rotates to pull the slide back to its original position, and the first motor works to drive the mobile carrier to rotate. After rotating into place, it stops rotating. At this time, the adsorption pressure head between the clamping blocks aligns the sponge strip with the pre-pasting area of ​​the mask, and pushes the cylinder to push the adsorption pressure head out to push the sponge strip to the pre-pasting position. The suction port on the adsorption pressure head stops sucking air, and the pasting is completed. All components are reset to complete a processing cycle. Since the stripped sponge strip is caught by the sponge strip receiving block, it is difficult to ensure the stability of the transferred sponge strip, and it is easy for the sponge strip to not be completely stripped from the material strip. Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0024] In actual application, when the sponge receiving mold 11 drives the sponge strip to move down to the position corresponding to the sponge strip attaching mechanism 6, the two clamping blocks 19 are in an open state, and the mobile driving mechanism 7 drives the sponge strip attaching mechanism 6 to move close to the sponge receiving mold 11 until the sponge attaching block 20 contacts the sponge strip on the sponge receiving mold 11, and the sponge strip is located between the two clamping blocks 19, and then the sponge strip clamping driver 18 drives the two clamping blocks 19 to move closer to each other until the two clamping blocks 19 clamp the upper and lower sides of the sponge strip, and then the mobile driving mechanism 7 drives the two clamping blocks 19 to move together with the sponge strip away from the sponge receiving mold 11 until Move to the position of the sponge strip (located below the mask body 33), and then the rotating driver 14 drives the rotating seat 16 to rotate upward relative to the base 15, so that the sponge strip, the sponge block 20 and the two clamping blocks 19 are tilted upward toward the inner wall of the mask body 33, and the supporting end of the sponge strip supporting mechanism 5 supports the outer wall of the mask body 33, and the sponge block 20 corresponds to the supporting end of the sponge strip supporting mechanism 5, and then the sponge strip clamping driver 18 drives the two clamping blocks 19 to open, and the sponge strip driver 17 drives the sponge block 20 to stick the sponge strip to the inner wall of the mask body 33.

[0025] In this embodiment, the sponge sticking block 20 is connected to the output end of the sponge sticking strip driver 17 via the buffer guide assembly 21. When the sponge sticking block 20 sticks the sponge strip to the inner wall of the mask body 33, the buffer guide assembly 21 plays a role of buffering and guiding, which not only improves the stability of the sponge sticking strip, but also plays a role of buffering protection during the sponge sticking process.
