Detailed implementation manners

[0015] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0016] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0017] As Figure 1 - Figure 7 shown, a fabric placing rack for a full-automatic mask machine includes a cross bar 1. A rotating rod is movably installed inside the cross bar 1. A stepper motor 2 is installed on the side of the cross bar 1. The output end of the stepper motor 2 is connected to the rotating rod. Three slotted grooves 3 are evenly formed on the surface of the cross bar 1. A rotating bracket 4 is installed inside each slotted groove 3. The rotating bracket 4 includes a central axis 5. The central axis 5 is located inside the slotted groove 3 and is fixedly installed on the surface of the rotating rod. Smooth rods 6 are rotatably installed at both ends of the central axis 5. Three fabric rolls 17 are arranged in front of the cross bar 1. The three fabric rolls 17 are respectively sleeved on the surfaces of the three smooth rods 6. A material clamping mechanism 19 is arranged on the side of each slotted groove 3. The material clamping mechanism 19 cooperates with the smooth rod 6 in front of the cross bar 1. By driving the rotating rod to rotate 180 degrees by the stepper motor 2, the rotating bracket 4 will also rotate 180 degrees at the same time, and the positions of the two smooth rods 6 will be interchanged. The new fabric roll 17 will move to the front of the cross bar 1 to realize the replacement of the fabric roll 17. At the same time, under the action of the material clamping mechanism 19, the fabric roll 17 can be clamped, and the stability of the smooth rod 6 during use can also be ensured.

[0018] The middle end surface of the light rod 6 is movably sleeved with a first locking block 7, a matching disk 11 is arranged behind the first locking block 7, a positioning disk 10 is fixedly arranged behind the matching disk 11, and the positioning disk 10 and the matching disk 11 are both fixedly mounted on the surface of the light rod 6, and a guide rod 14 is installed at one end of the first locking block 7 close to the matching disk 11, and the surface of the guide rod 14 movably penetrates the positioning disk 10 and the matching disk 11, and a tension spring 15 is installed on the surface of the guide rod 14 behind the positioning disk 10, and the surface of the first locking block 7 close to the matching disk 11 is arranged as a pushing surface 13, and the diameter of the pushing surface 13 is slightly smaller than the diameter of the matching disk 11, and the surface of the first locking block 7 away from the matching disk 11 is arranged as an inclined surface 12, and a cloth winding drum 18 is arranged at the center of the cloth roll 17, and sleeve surfaces 16 are provided at both ends of the cloth winding drum 18, and the inner diameter of the sleeve surface 16 matches the diameter of the matching disk 11, and the pushing surface 13 and the matching disk 11 are both arranged in the sleeve surface 16, and the staff can sleeve the cloth winding drum 18 on The outer surface of the first locking block 7 and the cloth winding drum 18 are pushed in the direction of the central axis 5. At this time, the step surface inside the sleeve surface 16 will push the pushing surface 13, so that the pushing surface 13 is in contact with the matching disk 11, so that the inner wall of the sleeve surface 16 can be clamped on the outer surface of the matching disk 11. Since the cloth roll 17 itself has a certain weight, the pushing surface 13 is also tightly in contact with the surface of the matching disk 11. In the process of the uniform turning of the rotating bracket 4, since the rear light rod 6 rotates upward, under the action of the cloth roll 17's own gravity, the cloth roll 17 will move downward, and the pushing surface 13 can always be in contact with the matching disk 11, so that the cloth roll 17 can achieve a stable effect. When the cloth of the cloth roll 17 is used up, the elastic force of the tension spring 15 can push the first locking block 7 forward. At this time, the pushing surface 13 at the end of the first locking block 7 can push the inner wall of the sleeve surface 16, so that the end of the cloth winding drum 18 is separated from the surface of the matching disk 11, which is convenient for the staff to remove the cloth winding drum 18.

[0019] A second locking block 8 is arranged in front of the first locking block 7, and the second locking block 8 is movably sleeved on the surface of the light rod 6. The end of the second locking block 8 away from the first locking block 7 is set as a pushing surface 13, and the end of the second locking block 8 close to the first locking block 7 is set as an inclined surface 12. The second locking block 8 corresponds to the first locking block 7. When the second locking block 8 moves toward the center axis 5, the second locking block 8 can be inserted into the inside of the cloth winding drum 18. At this time, the second locking block 8 and the first locking block 7 have a squeezing and fixing effect on the cloth winding drum 18.

[0020] The side of the slot 3 is provided with a fixing block 20. The material clamping mechanism 19 includes a cylinder 21. The cylinder 21 is installed behind the fixing block 20 through bolts. A telescopic rod 22 is movably arranged in front of the fixing block 20. The output end of the cylinder 21 is fixedly connected to the telescopic rod 22. An L-shaped rod 23 is fixedly installed in front of the telescopic rod 22. An installation ring 24 is fixedly arranged at the end of the L-shaped rod 23. A rotating ring is installed on the surface of the installation ring 24 close to the second clamping block 8. The surface of the rotating ring is fixedly connected to the second clamping block 8, and the diameter of the rotating ring is the same as the diameter of the matching disc 11. When the cylinder 21 drives the telescopic rod 22 to move, the telescopic rod 22 will drive the L-shaped rod 23 to move, and the L-shaped rod 23 can also drive the installation ring 24 and the second clamping block 8 to move. When the cylinder 21 extends, the telescopic rod 22 moves forward of the cross bar 1. At the same time, the L-shaped rod 23 drives the installation ring 24 and the second clamping block 8 to move forward. The surface of the second clamping block 8 will disengage from the inside of the cloth winding cylinder 18. Then when the cylinder 21 contracts, the telescopic rod 22 moves backward of the cross bar 1. At the same time, the L-shaped rod 23 drives the installation ring 24 and the second clamping block 8 to move backward. The surface of the second clamping block 8 can be inserted into the inside of the cloth winding cylinder 18.

[0021] Three positioning blocks 25 are evenly installed in front of the cross bar 1. The three positioning blocks 25 correspond to the three fixing blocks 20 respectively. A limiting groove 26 is opened on the surface of the positioning block 25. A sliding block 27 is slidably installed inside the limiting groove 26. A clamping groove 28 is opened at one end of the sliding block 27 close to the optical rod 6. A positioning surface 9 is arranged on the surface of the optical rod 6 close to the central axis 5. The clamping groove 28 is sleeved on the outer surface of the positioning surface 9. A second positioning pin 31 is installed in the middle of the top of the sliding block 27. A first positioning pin 30 is installed in the middle of the telescopic rod 22. A connecting rod 29 is installed between the second positioning pin 31 and the first positioning pin 30 through a rotating shaft. Through the second positioning pin 31 and the first positioning pin 30, when the telescopic rod 22 moves, the first positioning pin 30 can pull the connecting rod 29 and the second positioning pin 31, and the second positioning pin 31 can drive the sliding block 27 to move. When the cylinder 21 drives the telescopic rod 22 to extend outwards, the telescopic rod 22 can pull the sliding block 27 through the connecting rod 29, so that the sliding block 27 slides parallelly. At this time, the clamping groove 28 will disengage from the surface of the positioning surface 9. When the cylinder 21 drives the telescopic rod 22 to contract, the telescopic rod 22 can push the sliding block 27 through the connecting rod 29, so that the sliding block 27 slides parallelly. At this time, the clamping groove 28 will be clamped on the surface of the positioning surface 9, ensuring the stability of the optical rod 6 during operation.

[0022] Four legs are evenly installed at the bottom of the cross bar 1. The four legs evenly divide the lower part of the cross bar 1 into three bottom frames. The three bottom frames are respectively installed directly below the three slots 3. The legs can support the cross bar 1, ensuring the stability of the device during use.

[0023] Inside the bottom frame, there is a collection box 32. In front of the collection box 32, there is an arc surface 33 fixedly installed. The collection box 32 can accommodate the cloth winding cylinder 18. When the central shaft 5 rotates and the light rod 6 is perpendicular to the ground, the gravity of the cloth winding cylinder 18 will cause the cloth winding cylinder 18 to fall off from the surfaces of the mating disc 11 and the first clamping block 7, and the cloth winding cylinder 18 can fall into the collection box 32.

[0024] Working principle: First, after the cloth on the cloth roll 17 is used up, the staff sleeved a new cloth roll 17 on the surface of the light rod 6 behind the cross bar 1, sleeved the cloth winding cylinder 18 on the surface of the first clamping block 7, and made the sleeved surface 16 clamped on the surface of the mating disc 11. Then, the air cylinder 21 drives the telescopic rod 22 to extend forward. The telescopic rod 22 will move forward in front of the cross bar 1, and the L-shaped rod 23 drives the mounting ring 24 and the second clamping block 8 to move forward. The surface of the second clamping block 8 will disengage from the inside of the cloth winding cylinder 18, and the second clamping block 8 will move out from the surface of the light rod 6. While the telescopic rod 22 extends forward, the telescopic rod 22 can pull the sliding block 27 through the connecting rod 29, so that the sliding block 27 slides parallelly. At this time, the clamping groove 28 will disengage from the surface of the positioning surface 9. Since the second clamping block 8 does not apply an extrusion force to the cloth winding cylinder 18, the elastic force of the tension spring 15 can push the first clamping block 7 forward. At this time, the pushing surface 13 at the end of the first clamping block 7 can push the inner wall of the sleeved surface 16, so that the end of the cloth winding cylinder 18 disengages from the surface of the mating disc 11. Then, the stepping motor 2 drives the rotating rod to rotate, the rotating rod drives the rotating bracket 4 to rotate, the front light rod 6 moves downward, and the rear light rod 6 moves upward. During the rotation, the used cloth winding cylinder 18 will fall into the collection box 32 under the action of its own gravity through the arc surface 33. When the rotating bracket 4 rotates 180 degrees, the positions of the two light rods 6 are interchanged, and the new cloth roll 17 will move in front of the cross bar 1. Finally, when the air cylinder 21 contracts, the telescopic rod 22 moves backward behind the cross bar 1. At the same time, the L-shaped rod 23 drives the mounting ring 24 and the second clamping block 8 to move backward. The surface of the second clamping block 8 can be inserted into the inside of the cloth winding cylinder 18. At the same time, the telescopic rod 22 can push the sliding block 27 through the connecting rod 29, so that the sliding block 27 slides parallelly. At this time, the clamping groove 28 will be clamped on the surface of the positioning surface 9 to ensure the stability of the light rod 6 during operation.
