Description

Technical Field

[0001] The utility model relates to the technical field of textile industry, in particular to an automatic folding device. Background Art

[0002] The textile industry in China is a highly labor-intensive and externally dependent industry. China is the world's largest producer and exporter of textiles and clothing. Towels, bath towels, and wash towels are all textile products. Folding machines are required when folding towels and bath towels.

[0003] For example, the Chinese utility model patent with the announcement number CN208102534U discloses a fully automatic medical towel folding machine, including a first folding component, a second folding component and a third folding component. The first folding component can fold the medical towel once along the warp direction, the second folding component can fold the medical towel twice along the warp direction, and the third folding component can fold the medical towel once along the weft direction. The fully automatic medical towel folding machine first folds the medical towel once along the warp center line, and then folds the folded medical towel into a Z shape along the warp direction, and finally folds the Z-shaped medical towel once along the weft center line. The fully automatic medical towel folding machine replaces manual folding, avoids the pollution caused by manual folding, and quickly folds the medical towel into a folding structure that is easy to open, reduces the opening steps, and avoids the pollution caused by multi-step manual opening.

[0004] However, there are still some problems. Since the spacing between the input conveyor belt and the longitudinal folding conveyor belt is fixed, the thickness of the folded towels is fixed. However, the thickness of different types of towels is different. Especially after folding, the difference in the thickness of the towels will accumulate. Too thick or too thin will affect the folding effect of the towels, or even make them impossible to fold. This greatly restricts the working efficiency of the towel folder. Therefore, an automatic folding device is proposed to solve the above problems. Utility Model Content

[0011] Furthermore, the transmission assembly includes a driving wheel, three driven wheels and a transmission belt. The driving wheel is rotatably connected to the support plate and passes through the back of the support plate. The driven wheel is rotatably connected to the support plate. The outer surface of the adjustment plate is transmission-connected to the transmission belt.

[0012] By adopting this technical solution, the driving wheel is used to push the transmission belt to move, and the driven wheel can assist the transmission belt to move, thereby making the movement of the transmission belt more stable.

[0013] Furthermore, the plurality of positioning rods are fixed to the driving wheel and the driven wheel respectively, and the plurality of return springs are fixed to the driving wheel and the driven wheel respectively.

[0014] By adopting this technical solution, the adjustment component is located inside the driving wheel and the driven wheel, replacing the driving wheel and the driven wheel in supporting the transmission belt, thereby allowing the transmission belt to be adjusted.

[0015] Furthermore, sliding blocks are fixed on both the upper and lower sides of the pushing block, and sliding grooves are provided inside the driving wheel and the driven wheel for sliding connection with the sliding blocks.

[0016] By adopting this technical solution and providing a sliding block, the movement of the pushing block and the adjusting plate can be made more stable.

[0017] Furthermore, the moving assembly includes a limit block, a mounting block and a rotating rod. The limit block is fixed to the electric push rod, the back of the support plate is fixed to the mounting block, the interior of the mounting block is threadedly connected to the rotating rod, and the rotating rod is rotatably connected to the limit block.

[0020] Furthermore, a fixed bearing is fixed to the right side of the limit block, and the interior of the fixed bearing is fixed to the rotating rod.

[0026] 2. The automatic folding device can adjust the position of the electric push rod through the provided moving components, thereby adjusting the folding point of the towel. The provided linkage components can effectively save the driving source, thereby effectively reducing the use of the motor. The overall structure is simple, making the overall device more practical.

[0033] See also Figure 1-3 In this embodiment, an automatic folding device includes a base plate 1, a support plate 2 is fixed on the top of the base plate 1, and three transmission components 3 are provided on the front of the support plate 2.

The moving assembly is used to adjust the position of the electric push rod 6, and an air pump 10 is fixed on the top of the base plate 1.

[0035] Furthermore, the outer surfaces of the left transmission component 3 and the bottom transmission component 3 are connected by a linkage component 11.

[0036] In general, by rotating the rotating rod 9, the limit block 7 can push the electric push rod 6 to move, so that the electric push rod 6 can push different parts of the towel, thereby folding different points of the towel.

[0037] See also Figure 4The adjusting assembly 4 in this embodiment includes two positioning rods 401, a pushing block 402, an adjusting plate 403 and a return spring 404. The positioning rod 401 is fixed to the transmission assembly 3. The outer surface of the positioning rod 401 is slidably connected to the pushing block 402.

[0038] In general, taking the transmission component 3 on the left as an example, when the transmission belt 303 is squeezed, the right side of the transmission belt 303 will move toward the left, so that the left side of the transmission belt 303 and the adjustment plate 403 are in a relaxed state, and the return spring 404 inside the left driven wheel 302 will push the adjustment plate 403 to move to the left, thereby effectively preventing the transmission belt 303 from entering a relaxed state, and effectively ensuring the stability of the movement of the transmission belt 303.

[0039] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0040] The working principle of the above embodiment is:

[0041] (1) Place items such as towels that need to be folded on the transmission belt 303. Driven by the drive motor 12 and the servo motor 13, the driving wheel 301 pushes the transmission belt 303 to move clockwise. When the middle of the towel moves between the two top transmission belts 303, the electric push rod 6 is started, and the servo motor 13 is reversed, so that the middle of the towel is pushed into the gap between the two transmission belts 303. The servo motor 13 is reversed, which makes the transmission belt 303 on the top right move counterclockwise, thereby folding the towel and moving the towel downward. After half of the towel passes through the spray gun 5, the spray gun 5 is started, which pushes the towel from the middle of the towel to between the two right transmission belts 303 to complete further folding, thereby eliminating the need for manual folding, effectively improving the overall practicality.

[0042] (2) When the thickness of the towel is too large, it will cause a certain amount of squeezing on the transmission belt 303, thereby pushing the adjustment plate 403 to move to the side away from the towel, and then the spacing between the transmission belts 303 can be adjusted. When the transmission belt 303 moves to the side away from the towel, the friction between the adjustment plate 403 on the side away from the towel and the transmission belt 303 will be reduced, and the reset spring 404 will push the adjustment plate 403 to move toward the transmission belt 303, thereby supporting the transmission belt 303, thereby effectively ensuring the friction between the transmission belt 303 and the adjustment plate 403, so that the transmission belt 303 can be stably transmitted. The overall structure is simple, so that the spacing between the transmission belts 303 can be adjusted according to the thickness of the towel, making the overall structure more practical.
