Description

Technical Field

[0001] This utility model relates to the field of wet wipe production and processing technology, specifically a folding device for wet wipe production. Background Technology

[0002] A folding device for wet wipe production is a core piece of equipment for efficient wet wipe production. The device mainly consists of a conveying system, a folding mechanism, and a control system. During production, rolls of wet wipe raw materials are conveyed at a uniform speed through the conveying system and precisely arrive at the folding mechanism. The folding mechanism is equipped with folding plates and rollers of various shapes, which, through clever coordination, can quickly and neatly fold the wet wipes according to preset patterns, such as Z-shaped or tri-fold. The control system acts like a "commander," precisely controlling the conveying speed, folding frequency, and action sequence to ensure a smooth process. This folding device can flexibly adjust parameters according to different wet wipe sizes and packaging requirements, greatly improving production efficiency and ensuring that the folded wet wipes are uniformly sized and aesthetically pleasing, meeting diverse market demands.

[0003] A search revealed that Chinese patent CN219173876U discloses a folding device for wet wipe production. This patent describes a device that facilitates folding wet wipes by using an mounting plate, a folding frame body, and a fixing rod. A first infrared sensor detects the wet wipe extending and transmits a signal to a controller. The controller then transmits a signal to the fixing rod, which, under the action of a power device, lowers an insert rod. The insert rod inserts the wet wipe into a clamping plate, which clamps the wet wipe. The insert rod folds the wet wipe, which then extends through the folding frame body. A second infrared sensor detects the wet wipe extending and transmits a signal to the controller. The controller then transmits a signal to an outer plate, which, under the action of a power device, moves an inner plate. The inner plate catches the wet wipe, changing the vertical position of the wet wipe to a horizontal position, thus facilitating the folding of wet wipes.

[0004] While this solution facilitates the folding and conveying of wet wipes, the size of the wet wipes must be larger than the trough when they are conveyed to the trough via the second conveyor belt in order to perform the folding operation. This limits its applicability. When the size of the wet wipes is smaller than the trough, they will leak directly and cannot be folded, which is quite restrictive and affects processing efficiency. To solve this technical problem, this utility model proposes a folding device for wet wipe production. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] While this solution facilitates the folding and conveying of wet wipes, the size of the wet wipes must be larger than the trough when they are conveyed to the trough via the second conveyor belt in order to perform the folding operation. This limits its applicability. When the size of the wet wipes is smaller than the trough, they will leak directly and cannot be folded, which is quite restrictive and affects processing efficiency. To solve this technical problem, this utility model proposes a folding device for wet wipe production.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a folding device for wet wipe production, comprising a support frame, with side plates fixedly connected to both sides of the outer wall of the support frame, a motor fixedly connected to the outer wall of one side plate, a threaded rod fixedly connected to the output end of the motor, connecting blocks threadedly connected to the outer walls of both ends of the threaded rod, a connecting plate fixedly connected to the outer wall of each connecting block, a limit rod fixedly connected to the other end of each connecting plate, and the limit rod slidably connected inside the side plate, a placement plate fixedly connected to the outer wall of each connecting plate, and a roller rotatably connected inside each placement plate.

[0009] Preferably, a first conveyor belt is provided on the upper left side of the support frame, and a second conveyor belt is provided below the support frame. Both the second conveyor belt and the first conveyor belt are equipped with a second motor.

[0010] Preferably, a pair of fixing plates are fixedly connected to the outer wall of the support frame, a pair of mounting plates are fixedly connected between the two fixing plates, and a pair of clamping plates are provided between the two fixing plates.

[0011] Preferably, each of the clamping plates has a sliding rod fixedly connected to both sides of the clamping plate, and a pair of sliders are fixedly connected between the two sides of the clamping plate.

[0013] Preferably, the placement plate is flush with the upper surface of the first conveyor belt, and the push plate is located on the upper surface of the second conveyor belt.

[0014] (III) Beneficial Effects

[0015] This utility model provides a folding device for wet wipe production. It has the following beneficial effects:

[0016] (1) Conveyor belt 1 is responsible for conveying wet wipes. When it is necessary to adapt to wet wipes of different sizes, motor 1 on the outer wall of the side plate is started. Motor 1 drives the threaded rod to rotate. Due to the special design of the threaded rod, its rotation causes the connecting blocks at both ends to move in opposite directions, thereby driving the connecting plate, allowing the placement plate and internal rollers to move together. The connecting plate slides stably in the side plate by means of the limiting rod. This combination solves the problem that the existing device is difficult to flexibly adapt to wet wipes of different sizes and has low conveying efficiency. It realizes the automatic adjustment of the conveying structure spacing according to the size of the wet wipe, so that wet wipes of different specifications can be stably conveyed to the designated position, preparing for subsequent folding and other processes, improving the versatility and efficiency of the conveying link, reducing manual adjustment, optimizing the wet wipe production process, and improving the overall production efficiency.

[0017] (2) The clamping plate is installed on the mounting plate and connected to the sliding rod through the slider. A spring is sleeved on the outside of the sliding rod. When the electric push rod 2 pushes the insert plate down, the wet wipe is sent to the clamping plate. The clamping plate is squeezed and slides on the slider through the sliding rod, compressing the spring. The spring rebound force makes the clamping plate press the wet wipe tightly to achieve folding. Motor 2 can adjust the position of some parts as needed. After folding, the electric push rod 1 is started, which pushes the push plate. The push plate moves stably on a specific track with the help of the positioning rod, pushing the folded wet wipe onto the conveyor belt 2. This combination solves the problems of poor folding effect and low efficiency of the existing device, realizes efficient and accurate wet wipe folding and conveying, improves product quality and production efficiency, and meets the needs of large-scale production.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] Example 1: A folding device for wet wipe production includes a support frame 1. Side plates 3 are fixedly connected to both sides of the outer wall of the support frame 1. A motor 4 is fixedly connected to the outer wall of one side plate 3. A threaded rod 5 is fixedly connected to the output end of the motor 4. Connecting blocks 6 are threadedly connected to the outer walls of both ends of the threaded rod 5. A connecting plate 7 is fixedly connected to the outer wall of each connecting block 6. A limit rod 8 is fixedly connected to the other end of each connecting plate 7, and the limit rod 8 is slidably connected inside the side plate 3. A placement plate 9 is fixedly connected to the outer wall of each connecting plate 7. A roller 10 is rotatably connected inside each placement plate 9. A conveyor belt 2 is arranged on the upper left side of the support frame 1. A conveyor belt 17 is arranged below the support frame 1. A motor 18 is arranged outside both the conveyor belt 17 and the conveyor belt 2. The placement plate 9 is flush with the upper surface of the conveyor belt 2. A push plate 20 is located on the upper surface of the conveyor belt 17.

[0026] The wet wipes are transported by conveyor belt 2. When adjustments to the transport mechanism are needed based on the size of the wet wipes, motor 4 on the outer wall of side panel 3 is activated. Once motor 4 starts, its output shaft drives threaded rod 5 to rotate. Because the threads at both ends of threaded rod 5 rotate in opposite directions, their rotation causes connecting blocks 6 on the outer walls at both ends to move in opposite directions. This movement of connecting blocks 6, in turn, causes connecting plate 7 connected to them to move in the opposite direction. As connecting plate 7 moves, the placement plate 9 fixed to it and the rollers 10 inside it also move. During this process, the connecting plate 7 slides smoothly within side panel 3 under the limiting action of limiting rod 8, ensuring stable movement. When the distance between the two placement plates 9 is precisely matched to the width of the wet wipes, motor 4 stops, and conveyor belt 2 continues to operate, transporting the wet wipes to the adjusted placement plate 9, preparing for subsequent folding operations.

[0027] Example 2: The difference between this example and Example 1 is that, in this example, a pair of fixed plates 11 are fixedly connected to the outer wall of the support frame 1, a pair of mounting plates 13 are fixedly connected between the two fixed plates 11, a pair of clamping plates 12 are provided between the two fixed plates 11, a sliding rod 15 is fixedly connected to the two side walls of each clamping plate 12, a pair of sliders 14 are fixedly connected between the two fixed plates 11, and springs 16 are fixedly connected to both ends of the sliders 14, with the other end of the springs 16 fixedly connected to the outer wall of the sliding rods 15, and the sliding rods 15 are slidably connected to the outer wall of the sliders 14. An electric push rod 19 is fixedly connected to the lower outer wall of the side plate 3, a push plate 20 is fixedly connected to the output end of the electric push rod 19, a pair of positioning rods 21 are fixedly connected to the outer wall of the push plate 20, and the positioning rods 21 are slidably connected to the inside of the side plate 3. An electric push rod 22 is fixedly connected to the top of the support frame 1, and an insert plate 23 is fixedly connected to the output end of the electric push rod 22, with the insert plate 23 corresponding to the clamping plate 12.

[0028] Activate the electric push rod 22 at the top of the support frame 1. The push rod extends, pushing the insert plate 23 vertically downward. During the downward movement of the insert plate 23, the wet wipe is pushed between the two clamping plates 12. As the insert plate 23 continues to move downward, the clamping plates 12 are squeezed to both sides. The clamping plates 12 are limited by sliding on the slider 14 via the slide rod 15 to ensure stable movement. When the slide rod 15 moves, it compresses the spring 16. The spring 16 has elasticity. After the insert plate 23 stops pressing down, it will use its own elasticity to drive the slide rod 15, so that the clamping plate 12 is tightly pressed against the surface of the wet wipe on the insert plate 23, thereby completing the folding action of the wet wipe. After the wet wipe is detached from the clamping plate 12, the electric push rod 19 is activated. The electric push rod 19 works and pushes the push plate 20 forward. As the pusher plate 20 moves forward, the positioning rod 21 limits its movement on the side plate 3, ensuring the accuracy of the direction of movement. This flattens the vertically folded wet wipes and pushes them onto the conveyor belt 17.

[0029] Working principle: When the staff needs to fold the wet wipes, the wet wipes are first conveyed by conveyor belt 2. According to the size of the wet wipes, motor 4 on the outer wall of side plate 3 is started. Under the action of motor 4, the threaded rod 5 is rotated. When the threaded rod 5 rotates, it will drive the connecting blocks 6 on the outer walls at both ends to move in the opposite direction. When the connecting blocks 6 move, they will drive the connecting plate 7 to move in the opposite direction, and also drive the placement plate 9 and the internal rollers 10 to move together. When the connecting plate 7 moves, it is limited by the limiting rod 8 within the side plate 3 to ensure more stable movement. After the distance between the two placement plates 9 reaches the width of the wet wipe, the conveyor belt 2 transports the wet wipes onto the placement plate 9, thus facilitating the subsequent folding operation. At this time, the top of the support frame 1 is activated. The electric push rod 22 pushes the insert plate 23 downward and pushes the wet wipe between the two clamping plates 12. As it continues to move downward, the clamping plates 12 will move to both sides and be limited on the slider 14 by the slide rod 15. During the movement of the slide rod 15, the spring 16 will be compressed. The elasticity of the spring 16 will cause the clamping plate 12 on the slide rod 15 to stick tightly to the wet wipe on the insert plate 23, thereby achieving the folding effect. After the wet wipe is detached from the clamping plate 12, the electric push rod 19 is activated to push the push plate 20 forward and push the vertically folded wet wipe flat onto the conveyor belt 17. When the push plate 20 moves, it is limited on the side plate 3 by the positioning rod 21. Through their cooperation, a rapid folding effect is achieved, improving work efficiency.
