Abstract
Description
Technical Field
[0001] This utility model relates to the field of humidifier technology, and in particular to an automatic roll changing device for a humidifier. Background Technology
[0002] Wet kraft paper tape is a commonly used environmentally friendly tape. Before use, wet kraft paper tape needs to be moistened, usually by using a wet kraft paper tape machine to make it sticky.
[0003] However, existing wet kraft paper tape changers require opening the outer casing of the wet kraft paper tape, placing the tape inside, pulling out a portion of the tape, and placing the remaining tape on the conveyor. This process is cumbersome and results in low roll changing efficiency. Utility Model Content
[0004] To overcome the above-mentioned shortcomings, this utility model provides an automatic roll changing device for a wet kraft paper tape that facilitates quick replacement of wet kraft paper tape and facilitates the passage of the next wet kraft paper tape through the wet kraft paper tape machine, thereby improving the roll changing efficiency of the wet kraft paper tape machine.
[0005] An automatic roll changing device for a wet kraft paper tape dispenser includes a mounting frame, a closing cover, a placement frame, a servo motor, a changing component, a limiting component, and an adhesive component. The closing cover is connected to the mounting frame via a hinge. The placement frame is fixedly connected to the middle of the mounting frame, and several wet kraft paper tapes are placed on the placement frame. The servo motor is fixedly connected to the bottom surface of the mounting frame. The changing component is provided inside the mounting frame for changing the wet kraft paper tapes. The limiting component is provided at the top of the placement frame, and the adhesive component is provided on the bracket.
[0006] Optionally, the replacement components include a slide rail, a support plate, a lifting frame, a partition, a placement frame, a transmission frame, a push frame, and a support spring. The slide rail is fixed to the bottom surface of the mounting frame, the support plate is slidably connected to the slide rail, the lifting frame is slidably connected to the support plate, several partitions are fixed to the lifting frame, the placement frame is fixed to the top of the placement frame, the transmission frame is fixed to the output shaft of the servo motor, the push frame is rotatably connected to one side of the lifting frame, the transmission frame and the push frame are slidably connected, and a support spring connects the transmission frame and the push frame.
[0007] Optionally, the limiting assembly includes a bracket, a limiting frame, a rotating roller, a limiting roller, and a limiting wheel frame. The bracket is fixedly connected to the upper part of the placement frame, the limiting frame is fixedly connected to the bracket, the rotating roller is rotatably connected to the limiting frame, the limiting roller is placed on the limiting frame, and the limiting wheel frame is rotatably connected to one side of the limiting frame.
[0008] Optionally, the adhesive assembly includes a base plate, a pressing frame, a return spring, and absorbent cotton. The base plate is fixedly attached to the upper part of the support, and the pressing frame is slidably connected to the base plate. The pressing frame has two storage slots. A return spring is connected between the upper part of the pressing frame and the base plate. Two absorbent cottons are fixedly attached to the pressing frame, and the upper part of the absorbent cottons is located in the storage slots on the pressing frame.
[0009] The beneficial effects of this utility model are as follows: When the worker starts the output shaft of the servo motor, it rotates one revolution in reverse. This rotation drives the transmission frame, push frame, and support spring to rotate in reverse. The push frame drives the lifting frame and partition to rotate in reverse around the servo motor. The lifting frame drives the support plate to move to the left, separating the support plate from the right end of the slide rail frame. The support plate guides the lifting frame and partition, keeping the partition vertical. The partition's rotation pushes the wet kraft paper tape in the placement frame to move a certain distance to the left, so that one end of the next wet kraft paper tape is above the bottom plate. Then, the output shaft of the servo motor continues to rotate in reverse, driving the transmission frame, push frame, and support spring to rotate and reset. The push frame pushes the lifting frame and partition to move vertically upward and reset. The support spring is compressed again, and the partition re-engages with the wet kraft paper tape, limiting the wet kraft paper tape. In this way, the wet kraft paper tape can be replaced quickly.
[0010] The servo motor's output shaft reverses, driving the transmission frame, push frame, and support spring to reverse as well. The push frame pushes the lifting frame and partition to move vertically downwards, while the lifting frame pushes the pressing frame and absorbent cotton downwards. The return spring is compressed, and the absorbent cotton comes into contact with the other end of the previous wet kraft paper tape. Then, the pressing frame squeezes the absorbent cotton and the two layers of wet kraft paper tape, causing the water inside the absorbent cotton to flow out and moisten the two layers of wet kraft paper tape, making the ends of the two wet kraft paper tapes stick together. This facilitates the unwinding of the next wet kraft paper tape. When the wetting machine is running, it pulls the portion of the previous wet kraft paper tape and one end of the next wet kraft paper tape, thus driving the next wet kraft paper tape through the wetting machine and unwinding the next wet kraft paper tape.

Detailed Implementation
[0020] The embodiments of this utility model will be described below with reference to the accompanying drawings.
[0021] Example 1: An automatic roll changing device for a wetter, such as Figures 1-8 As shown, it includes an installation frame 1, a closing cover 2, a placement frame 3, a servo motor 4, a replacement component, a limiting component, and an adhesive component. The closing cover 2 is connected to the installation frame 1 via a hinge. The placement frame 3 is welded to the middle of the installation frame 1. Several wet kraft paper tapes 82 are placed on the placement frame 3. The servo motor 4 is connected to the bottom surface of the installation frame 1 via bolts. The replacement component is provided inside the installation frame 1. The replacement component is used to replace the wet kraft paper tapes 82. The limiting component is provided on the upper part of the placement frame 3. The adhesive component is provided on the bracket 12.
[0022] The replacement components include a slide rail frame 5, a support plate 6, a lifting frame 7, a partition 8, a placement frame 81, a transmission frame 9, a push frame 10, and a support spring 11. The slide rail frame 5 is bolted to the bottom of the mounting frame 1. The support plate 6 is slidably connected to the slide rail frame 5. The lifting frame 7 is slidably connected to the support plate 6. Several partitions 8 are welded to the lifting frame 7. The placement frame 81 is welded to the upper part of the placement frame 3. The output shaft of the servo motor 4 is fixedly connected to the transmission frame 9. The push frame 10 is rotatably connected to one side of the lifting frame 7. The transmission frame 9 and the push frame 10 are slidably connected. The support spring 11 is connected between the transmission frame 9 and the push frame 10 through a hook.
[0023] The limiting assembly includes a bracket 12, a limiting frame 13, a rotating roller 14, a limiting roller 15, and a limiting wheel frame 16. The bracket 12 is welded to the upper part of the placement frame 3, the limiting frame 13 is welded to the bracket 12, the rotating roller 14 is rotatably connected to the limiting frame 13, the limiting roller 15 is placed on the limiting frame 13, and the limiting wheel frame 16 is rotatably connected to one side of the limiting frame 13.
[0024] The adhesive assembly includes a base plate 17, a pressing frame 18, a return spring 19, and absorbent cotton 20. The base plate 17 is welded to the upper part of the bracket 12. The pressing frame 18 is slidably connected to the base plate 17. The pressing frame 18 has two storage slots. The return spring 19 is connected to the upper part of the pressing frame 18 and the base plate 17 by a hook. Two absorbent cotton 20s are fixed to the pressing frame 18. The upper part of the absorbent cotton 20 is located in the storage slot on the pressing frame 18.
[0025] Initially, the pusher 10 compresses the support spring 11. The worker opens the closing cover 2 and places four wet kraft paper tapes 82 on the placement frame 3, ensuring one wet kraft paper tape 82 is placed between each pair of adjacent partitions 8. Then, the worker places a portion of the wet kraft paper tape 82 on the placement rack 81, passing the leftmost wet kraft paper tape 82 through the rotating roller 14 and the limiting roller 15. The leftmost wet kraft paper tape 82 is then inserted into the wetting machine. During operation, the wetting machine pulls the leftmost wet kraft paper tape 82, causing it to unwind. When the leftmost wet kraft paper tape 82 is almost exhausted, the leftmost wet kraft paper tape... With the other end of the 82 glue positioned above the base plate 17, the worker turns off the wet machine and then starts the output shaft of the servo motor 4, reversing it one revolution. This reversal of the servo motor 4's output shaft drives the transmission frame 9, push frame 10, and support spring 11 to reverse. The push frame 10 slides along the transmission frame 9 away from the servo motor 4, pushing the lifting frame 7 and partition 8 vertically upwards. The support spring 11 rebounds. Then, the output shaft of the servo motor 4 continues to reverse, driving the transmission frame 9, push frame 10, and support spring 11 to continue reversing. The push frame 10 drives the lifting frame 7 and partition 8 to reverse around the servo motor 4. The lifting frame 7 moves the support plate 6 to the left, separating it from the right end of the slide rail frame 5. The support plate 6 guides the lifting frame 7 and partition 8, keeping the partition 8 vertically oriented. The partition 8 reverses and pushes the wet kraft paper tape 82 in the placement frame 3 to move to the left a certain distance, so that one end of the next wet kraft paper tape 82 is above the base plate 17. Then the support plate 6 contacts the left end of the slide rail frame 5. Then the output shaft of the servo motor 4 continues to reverse, driving the transmission frame 9, the push frame 10 and the support spring 11 to continue to reverse. The push frame 10 pushes the lifting frame 7 and the partition 8 to move vertically downward. The partition 8 separates from the wet kraft paper tape 82, the support spring 11 is compressed, and the lower side of the upper part of the lifting frame 7 contacts the upper side of the support plate 6. Then the output shaft of the servo motor 4 continues to reverse, driving the transmission frame 9, the push frame 10 and the support spring 11 to continue to reverse. The push frame 10 pushes the lifting frame 7 and the partition 8 to move horizontally to the right. The support plate 6 contacts the slide rail frame. 5. After the right end contacts, the output shaft of the servo motor 4 continues to reverse, driving the transmission frame 9, push frame 10, and support spring 11 to continue to reverse and reset. The push frame 10 pushes the lifting frame 7 and partition 8 to move vertically upward and reset. The support spring 11 is compressed again, and the partition 8 re-contacts the wet kraft paper tape 82. The partition 8 limits the wet kraft paper tape 82. When the wet kraft paper tape 82 on the placement frame 3 is used up, the worker opens the closing cover 2 and places three new wet kraft paper tapes 82 on the placement frame 3, so that the three wet kraft paper tapes 82 are located between the four partitions 8 on the right. Then, the output shaft of the servo motor 4 is started to reverse one revolution to replace the next wet kraft paper tape 82 between the two leftmost partitions 8.This ensures that one end of the next wet kraft paper tape 82 is positioned above the base plate 17, allowing for quick replacement of the wet kraft paper tape 82.
[0026] Initially, the worker adds a small amount of water to the storage tank on the pressing frame 18. The water in the storage tank on the pressing frame 18 is absorbed by the absorbent cotton 20. When the partition 8 reverses and pushes the wet kraft paper tape 82 in the placement frame 3 to move to the left a certain distance, the limit wheel frame 16 squeezes one end of the next wet kraft paper tape 82 to move downwards, so that when one end of the next wet kraft paper tape 82 is above the base plate 17, one end of the next wet kraft paper tape 82 is below the other end of the previous wet kraft paper tape 82. Then, the output shaft of the servo motor 4 continues to reverse, driving the transmission frame 9, the push frame 10 and the support spring 11 to continue to reverse. The push frame 10 pushes the lifting frame 7 and the partition 8 to move vertically downwards. The lifting frame 7 pushes the pressing frame 18 and the absorbent cotton 20 to move downwards. The reset spring 19 is compressed, and the absorbent cotton 20 and the previous wet kraft paper tape 82 are separated. The other end of the kraft paper tape 82 contacts the press frame 18, which then squeezes the absorbent cotton 20 and the two layers of wet kraft paper tape 82. The water in the absorbent cotton 20 flows out and wets the two layers of wet kraft paper tape 82, causing the ends of the two wet kraft paper tapes 82 to stick together. This facilitates the unwinding of the next wet kraft paper tape 82. Then, the push frame 10 pushes the lifting frame 7 and the partition 8 to move vertically upwards and reset. The lifting frame 7 separates from the press frame 18, and the reset spring 19 rebounds, causing the press frame 18 and the absorbent cotton 20 to move downwards and reset. Then, when the wet machine is running, the wet machine pulls the part of the previous wet kraft paper tape 82 and one end of the next wet kraft paper tape 82, thereby driving the next wet kraft paper tape 82 through the wet machine and unwinding the next wet kraft paper tape 82.
