[0001] The invention relates to the technical field of mask machines, and in particular to a mask machine ear line tightness adjustment device and a mask machine ear line feeding method. Background Art

[0002] In the production process of various mask machines, welding ear straps is a discrete process, that is, a section of ear wire is cut off within a certain period of time to be welded as the ear strap of the mask. In this production mode, the mask machine must use a certain mechanism to organize the ear wires so that the wire pulling mechanism can intermittently extract the ear straps of appropriate lengths. The existing mask machine can only adjust the tightness of the ear wires through a fixed rubber ring. This mechanism is inconvenient to debug and cannot adjust the tightness of the ear wires in the ready state, resulting in problems such as the ear wires running off. In addition, the current wire feeding structure of the mask machine directly adopts the method of feeding and drawing wires. In this process, jamming problems often occur, which ultimately leads to negative effects such as a reduction in the average trouble-free working time of the mask machine and a decrease in the production efficiency of the entire machine.

[0029] like Figure 1 The present embodiment shows a mask machine ear line tightness adjustment device, including a pole assembly, a sliding member 6, a counterweight 5, a stopper 4, a support base 7 and a fixed base 1. The pole assembly is arranged vertically, the sliding member 6 is connected to the pole assembly in a vertical sliding manner, the sliding member 6 is provided with a guide groove capable of guiding the ear line, the sliding member 6 has a vertical sliding stroke driven by the ear line, and the pole assembly is also slidably connected with a detachable counterweight 5, the counterweight 5 is located on the movement path of the sliding member 6, and the counterweight 5 has a synchronous sliding stroke with the sliding member 6 driven by the sliding member 6. That is, when the ear line is pulled by the wire drawing mechanism of the mask machine, the sliding member 6 and the counterweight 5 are driven to slide upward on the pole assembly, and after the wire drawing is completed, the sliding member 6 and the counterweight 5 will return to their original positions under the action of gravity; in this process, by changing the number of counterweights 5, the resistance borne by the ear line during the wire drawing process can be effectively adjusted, and thus the tightness of the ear line can be effectively adjusted. At the same time, through the cooperation of the vertical pole assembly and the sliding part 6, a buffer process is added during the feeding and drawing of the ear wire, which avoids the jamming of the ear wire during the drawing process, greatly improves the efficiency of debugging the tightness of the ear wire of the mask machine, and facilitates the later maintenance of the equipment, and increases the average trouble-free working time of the mask machine, thereby improving the production efficiency of the mask machine.

[0030] As a preferred embodiment, the vertical pole assembly includes a first vertical pole 2 and a second vertical pole 3 which are parallel to each other, and the sliding member 6 is a movable pulley arranged between the first vertical pole 2 and the second vertical pole 3, wherein the axle of the movable pulley is in contact and sliding connection with the first vertical pole 2 and the second vertical pole 3, and the counterweight 5 is located on the moving path of the axle and / or the wheel of the movable pulley. The guide groove is arranged on the axle of the movable pulley, that is, the part of the ear line on the sliding member 6 is in a U shape. Further preferably, the vertical pole assembly is provided with a limiter 4 which can limit the sliding of the counterweight 5 or the movable pulley, and plays a certain limiting role; wherein the limiter 4 is a rubber ring arranged on the first vertical pole 2 or the second vertical pole 3, and the rubber ring is arranged at a position of one-third of the length from the top to the bottom of the first vertical pole 2 or the second vertical pole 3.

[0031] As a preferred real-time method, the support base 7 is detachably connected to the bottom of the first vertical pole 2 and the second vertical pole 3 by bolts, and is used to adjust the initial position of the movable pulley on the vertical pole assembly so that the slider 6 faces the sensor of the ear wire feeding mechanism on the mask machine. The fixed base 1 is detachably connected to the top of the first vertical pole 2 and the second vertical pole 3 by bolts, which can not only play a fixing role, but also be used to connect the mask machine.

[0032] It should be noted that the counterweight 5 in this embodiment is a compressed air pipe with an axial opening, whose length is less than 1 cm and whose two ends are flat, and the inner diameter of the compressed air pipe is larger than the outer diameter of the first vertical pole 2 and / or the second vertical pole 3. The specific number of the counterweights 5 in this embodiment is determined by the material and tightness requirements of the ear wire, and the staff can increase or decrease it as required.

[0033] It should be noted that in this embodiment, the position limiting member 4 and the first upright pole 2 or the second upright pole 3 are in interference fit, and the staff can move the position of the position limiting member 4 on the first upright pole 2 or the second upright pole 3 without using tools.

[0034] The present embodiment also discloses a method for feeding ear wires of a mask machine, using the above-mentioned tightness adjustment device for the ear wires of the mask machine. First, two smooth first vertical poles 2 and second vertical poles 3 are placed in the fixed base 1 and tightened with fixing bolts, keeping the first vertical poles 2 and the second vertical poles 3 parallel and perpendicular to the lower plane of the fixed base 1. Then, the fixed base 1 is installed at the relevant position of the mask machine with two screws, keeping most of the first vertical poles 2 and the second vertical poles 3 at the bottom. Then, the limiter 4 is placed at one-third of the first vertical pole 2 or the second vertical pole 3. Then, the sliding member 6 and the supporting base 7 are installed, wherein the sliding member 6 can slide freely up and down between the first vertical pole 2 and the second vertical pole 3, and the position of the supporting base 7 just makes the sliding member 6 block the sensor of the ear wire feeding mechanism on the mask machine, so that the sensor works, and the ear wire feeding mechanism does not work at this time. When the ear wire drawing mechanism of the mask machine moves, the ear wire drives the slider 6 to move upward, leaving the position blocking the sensor, the sensor state changes, the ear wire feeding mechanism works, conveys the ear wire, and moves the slider 6 downward until it contacts the support base 7 and blocks the sensor again. Then install the ear wire, and the lowest point of the ear wire is the U-shaped structure on the guide groove of the slider 6. When the mask machine trial produces a mask, check whether the length of the mask ear wire is appropriate and whether the tightness of the ear wire is appropriate. If the length is too long or the ear wire is not tight enough, add a counterweight 5 to the first vertical pole 2 or the second vertical pole 3. In other cases, the ear wire length adjustment structure, the position of the positioning rubber ring, and other methods can be combined for step-by-step debugging, or a counterweight 5 can be added or reduced. Finally, the length of the mask ear strap produced meets the national standards, the ear wire tension is appropriate in the preparation stage, and the entire ear wire input structure has high reliability and low failure rate.

[0035] The above-mentioned mask machine ear wire feeding method specifically includes the following steps:

[0036] Step 1, adjust the position of the support base 7 so that the sliding member 6 is directly opposite to the sensor of the ear wire feeding mechanism of the mask machine;

[0037] Step 2, adjusting the number of weights 5 based on the tightness of the ear wire;

[0038] Step 3, the outlet end of the ear wire passes through the ear wire feeding mechanism and the sliding member 6 in sequence and is connected to the ear wire drawing mechanism, wherein the part of the ear wire on the sliding member 6 is in a U shape;

[0039] Step 4, start the ear wire drawing mechanism to pull the ear wire, so that the sliding member 6 moves upward and away from the sensor under the drive of the ear wire, thereby triggering the sensor;

[0040] Step 5, the triggered sensor controls the start-up of the ear wire feeding mechanism to complete the ear wire feeding work.
