Description

Technical Field

[0002] Fiber face towels, also known as towels, are a type of towel. Face towels are also frequently used items in people's daily lives, especially in consumer places such as hotels, restaurants, and guesthouses. These places require face towels to be folded into various shapes, which not only makes them easy to store and transport but also makes them convenient for consumers to use.

[0003] Traditional face towel folding methods involve folding the face towel into an "egg roll" shape. This folding method is usually done manually.

[0030] In use, firstly, the worker places several face towels 4 on the top of the platform 3 and starts the servo motor 13. When the servo motor 13 starts, it drives the adhesive roller 5 to rotate via the power output shaft. At the same time, the servo motor 13 drives the drive gear 51 to rotate via the power output shaft. The drive gear 51 drives the driven gear 50 to rotate. The rotation of the driven gear 50 drives the transmission shaft to rotate via the first rotating shaft and belt 33. The transmission shaft drives the unloading roller 10 to rotate. When the adhesive roller 5 contacts the face towels 4, it can move the face towels 4 to the right and wrap them around the outside of the adhesive roller 5. At this time, when the face towels 4 move, the friction of the face towel surface can drive the bonding wheel 41 to rotate. When the bonding wheel 41 rotates, it drives the gear 44 to rotate clockwise via the second rotating shaft. 4. Clockwise rotation can drive rack 45 to move upward. Rack 45 can drive lifting rod 47 to move upward through L-shaped connecting rod 46. Lifting rod 47 can limit the movement trajectory through lifting block 48. At the same time, when L-shaped connecting rod 46 moves upward, it can contact limit switch 42. When limit switch 42 is activated, servo motor 13 can be reversed through cable 34. When the power output shaft of servo motor 13 is reversed, the unloading roller 10 can be reversed, thereby contacting the hanging face towel 4 and transferring the face towel 4 to the surface of conveyor belt 14. After the above steps are completed, first cylinder 2 moves downward, so that the remaining face towel 4 is separated from the contact with bonding wheel 41. At the same time, lifting block 48 returns to its original position under the force of spring 49, so that rack 45 is reset.

[0032] When in use, when the face towel 4 moves to the left side of the inclined plate 20, a part of the face towel 4 can climb onto the surface of the inclined plate 20 and contact the sensor on the L-shaped stop bar 19. When the sensor is activated, the second cylinder 56 can be activated. The second cylinder 56 can drive the rotating block 55 to flip to the left through the U-shaped plate 54. When the rotating block 55 flips to the left, it can drive the inclined plate 20 to flip to the left. At this time, the face towel 4 completes the first fold.

The two support frames 16 are symmetrically arranged front and back. A coiling baffle 17 is fixedly connected between the two support frames 16.

[0034] In use, when the front and back sides of the initially folded face towel 4 come into contact with the adjacent flip plate 32, it enters the sensing range of the reflective photoelectric sensor 22. When the reflective photoelectric sensor 22 is activated, it can activate two electric telescopic rods 30. The two electric telescopic rods 30 can move the arc-shaped pressing plate 18 downward along the arc-shaped groove through the adjacent steel cable 36, thereby pressing the face towel 4. At the same time, when the electric telescopic rods 30 are activated, a trigger switch can be activated. When the trigger switch is activated, it can activate the flip motor 57. The flip motor 57 can drive the rotating plate 58 to rotate through the power output shaft. The rotating plate 58 can drive the adjusting plate 60 to swing through the guide groove. The adjusting plate 60 can drive the reciprocating plate 63 to swing through the transmission plate 61. The reciprocating plate 63 is connected to the lifting frame. 68 can drive the positioning plate 66 to swing. When the positioning plate 66 swings, it can drive the linkage plate 69 to move. When the linkage plate 69 moves along the trajectory of the arc plate 65, it can rotate 90 degrees, thereby flipping the flipping plate 32 to achieve the purpose of flipping the face towel 4 a second time. When the second flipping step is completed, the electric telescopic rod 30 returns to its original position, and the reset wheel 29 reverses under the force of the spring, thereby pulling the arc-shaped pressing plate 18 upward. The face towel 4, which has been folded twice, can continue to move to the right and fit with the rolling baffle 17. Since a wedge-shaped space is formed between the left side of the rolling baffle 17 and the conveyor belt 14, when the face towel 4 comes into contact with the inner wall of the rolling baffle 17, it can be rolled up under the force of the wedge space and the conveyor belt 14, and finally rolled up.

[0035] Working principle: First, the worker places several face towels 4 on the top of the platform 3 and starts the servo motor 13. When the servo motor 13 starts, it drives the adhesive roller 5 to rotate through the power output shaft. At the same time, the servo motor 13 drives the drive gear 51 to rotate through the power output shaft. The drive gear 51 drives the driven gear 50 to rotate. The rotation of the driven gear 50 drives the transmission shaft to rotate through the first rotating shaft and belt 33. The transmission shaft drives the unloading roller 10 to rotate. When the adhesive roller 5 contacts the face towels 4, it can move the face towels 4 to the right and wrap them around the outside of the adhesive roller 5. At this time, when the face towels 4 move, the friction of the face towel surface can drive the bonding wheel 41 to rotate. When the bonding wheel 41 rotates, it drives the second rotating shaft to rotate. The gear 44 can be driven to rotate clockwise, which in turn drives the rack 45 to move upward. The rack 45, via the L-shaped connecting rod 46, drives the lifting rod 47 to move upward. The lifting rod 47, via the lifting block 48, can limit its movement trajectory. Simultaneously, when the L-shaped connecting rod 46 moves upward, it contacts the limit switch 42. When the limit switch 42 is activated, the servo motor 13 reverses via the cable 34. When the power output shaft of the servo motor 13 reverses, the unloading roller 10 reverses, thus contacting the falling face towel 4 and transferring it to the surface of the conveyor belt 14. After the above steps are completed, the first cylinder 2 moves downward, causing the remaining face towel 4 to disengage from the contact wheel 41. The lifting block 48 returns to its original position under the force of the spring 49, causing the rack 45 to reset. When the towel 4 moves to the left side of the inclined plate 20, a part of the towel 4 can climb onto the surface of the inclined plate 20 and contact the sensor on the L-shaped stop bar 19. When the sensor is activated, the second cylinder 56 can be activated. The second cylinder 56 can drive the rotating block 55 to flip to the left through the U-shaped plate 54. When the rotating block 55 flips to the left, it can drive the inclined plate 20 to flip to the left. At this time, the towel 4 completes the first fold. After the fold is completed, the towel 4 can move to the left side of the secondary folding mechanism through the gap between the inclined plate 20 and the conveyor belt 14. When the front and rear sides of the initially folded towel 4 contact the adjacent flipping plate 32, it can enter the reflective photoelectric sensor. Within the sensing range of device 22, when the reflective photoelectric sensor 22 is activated, it can activate two electric telescopic rods 30. The two electric telescopic rods 30, via adjacent steel cables 36, can move the arc-shaped pressing plate 18 downward along the arc-shaped groove, thereby pressing the face towel 4. At the same time, when the electric telescopic rods 30 are activated, a trigger switch can be activated. When the trigger switch is activated, a flip motor 57 can be activated. The flip motor 57 can drive the rotating plate 58 to rotate via a power output shaft. The rotating plate 58 can drive the adjusting plate 60 to swing via a guide groove. The adjusting plate 60 can drive the reciprocating plate 63 to swing via a transmission plate 61. The reciprocating plate 63 can drive the positioning plate 66 to swing via a lifting frame 68. When the positioning plate 66 swings, it can drive the linkage plate 69 to move.As the linkage plate 69 moves along the trajectory of the arc-shaped plate 65, it can rotate 90 degrees, thereby flipping the flipping plate 32 and achieving a secondary flipping of the face towel 4. When the secondary flipping step is completed, the electric telescopic rod 30 returns to its original position, and the reset wheel 29 reverses under the force of the spring, thereby pulling the arc-shaped pressing plate 18 upward. The face towel 4, which has been folded twice, can continue to move to the right and fit against the rolling baffle 17. Since a wedge-shaped space is formed between the left side of the rolling baffle 17 and the conveyor belt 14, when the face towel 4 contacts the inner wall of the rolling baffle 17, it can be rolled up under the force of the wedge space and the conveyor belt 14, and finally rolled up.
