Description

Technical Field

[0001] This invention relates to the field of wet wipe substrate production equipment, and more particularly to a fully automatic wet wipe liquid dispensing equipment and liquid dispensing process. Background Technology

[0002] As a cleaning product, wet wipes have brought great convenience to people's daily lives due to their portability and disinfection capabilities, resulting in increasingly larger usage. The manufacturing process of wet wipes involves steps such as feeding, folding, adding liquid, cutting, shaping, and packaging the wet wipe substrate. The current traditional process involves adding liquid to the fabric substrate first, and then folding it. Patent application number CN201921513003X discloses a wet wipe production line liquid-adding device, which adds liquid to the non-woven fabric in a liquid-adding tank before folding. This traditional liquid-adding process, where water is added before folding, causes the wet fabric substrate to stick to the conveyor when transported to the next process, leading to fabric deformation, poor shaping, and poor product quality. This results in reduced production speed, lower product quality, and lower output. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a fully automatic wet wipe liquid dispensing device and liquid dispensing process.

The two end plates of the flip-type clamp are fixed to the upper crossbeam of the frame. The inner side of the lower part of the end plate is rotatably connected to the clamp support assembly via a rotating shaft. The inner plate of the assembly is fixedly connected to the inner end of the wheel axle. The outer end of the wheel axle is equipped with a driven wheel. One side of the inner plate is provided with a fixed seat, and the other side is connected to a movable seat via a transverse slide rod. A cylinder A is installed inside the fixed seat to drive the movable seat to move. A clamp assembly is connected between the fixed seat and the movable seat. The fixed clamp plate of the clamp assembly is connected between the two fixed seats, and the movable clamp plate is connected between the two movable seats. The inner sides of the fixed clamp plate and the movable clamp plate are provided with several slots at equal intervals. A driving wheel is installed on the upper part of the end plate and connected to the driven wheel via a belt. The two driving wheels are connected by a synchronous shaft A, and a drive source for driving the driving wheel to rotate is installed on one end plate.

[0005] Preferably, the bidirectional gripping device includes two symmetrically arranged cross-shaped single-belt machines. A bidirectional gripping mechanism is installed between the upper ends of the two vertical support plates of the two cross-shaped single-belt machines. Both ends of the mechanism are provided with seat plates. A clamping rod assembly A and a clamping rod assembly B are installed between the two seat plates. The clamping rod assembly A and the clamping rod assembly B are identical and symmetrically arranged.

[0006] Preferably, the clamping rod assembly A includes a lower crossbar fixedly connected between the two seat plates, an upper crossbar slidably mounted between the seat plates via a vertical slide bar, a cylinder B on the seat plate for driving the upper crossbar to move up and down, a plurality of upper clamping rods vertically arranged on the outer side of the upper crossbar, and a plurality of lower clamping rods vertically arranged on the outer side of the lower crossbar, with the upper clamping rods or lower clamping rods in the two clamping rod assemblies having opposite directions.

[0007] Preferably, the liquid dispensing mechanism includes a cross-shaped single-belt machine B. A cylinder C is vertically mounted on the inner end of the horizontal support plate of the cross-shaped single-belt machine B. A nozzle assembly is mounted on the lower end of the piston rod of the cylinder C. The nozzle assembly includes a square housing and a cylinder D. A liquid inlet pipe is provided on one side of the square housing. The square housing is slidably mounted below the cylinder D by a vertical slide column and is driven to move up and down by the cylinder D. A plurality of spray holes are evenly provided on the bottom surface of the square housing. A sealing plate is provided inside the housing above the spray holes. The lower end of the vertical slide column is fixedly connected to the sealing plate. A sealing gasket is provided around the spray holes, and the edge of the sealing plate can be horizontally pressed against the surface of the sealing gasket.

[0008] Preferably, a horizontal receiving plate is provided below the clamping plate assembly, and a vertical driving assembly is installed at the lower end of the end plate. The two driving assemblies drive the horizontal receiving plate to move up and down.

[0009] Preferably, the feeding conveyor includes several belt conveyor components arranged side by side, with a certain gap between the belt conveyor components.

[0010] Preferably, the discharge conveyor is a roller conveyor, and there is a certain gap between the conveying rollers of the roller conveyor.

[0011] A liquid dispensing process for a fully automatic wet wipe dispensing device includes the following steps: ① Fold the dry wet wipe substrate with a folding device to form a strip substrate with a certain thickness, and then put it on the feeding conveyor and send it to one side of the frame. ②The two clamping rod assemblies in the bidirectional gripping device move toward the wet wipe substrate under the drive of the cross-shaped single-belt mech, and clamp the wet wipe substrate through the clamping rod assembly A; ③ The movable clamping plate in the flip-type clamping plate assembly moves outward, so that sufficient clamping space is formed between the fixed clamping plate and the movable clamping plate. Then the clamping plate assembly rotates freely so that the direction of the slot on the clamping plate is consistent with the direction of the clamping rod in the clamping rod assembly. ④ The clamping rod assembly A clamps the wet wipe substrate into the clamping space of the clamping plate assembly. The movable clamping plate moves inward to clamp the wet wipe substrate. The upper clamping rod and the lower clamping rod enter the slot to avoid being clamped by the two fixed clamping plates and the movable clamping plate. Then the clamping rod assembly A leaves the clamping plate assembly to complete the feeding. ⑤ The clamping plate assembly rotates freely to adjust the unclamped surface of the wet wipe substrate to a horizontal state. The nozzle assembly of the liquid dispensing mechanism moves to above one end of the wet wipe substrate and then sprays liquid while moving to the other end to add liquid. After the liquid is added to one side of the wet wipe substrate, the clamping plate assembly rotates freely to adjust the other side of the wet wipe substrate to the top to add liquid, ensuring that the liquid fully and evenly penetrates into the cloth strip substrate. ⑥ Clamping rod assembly A clamps the new wet wipe substrate according to step ②. Then the clamping plate assembly rotates freely to readjust the direction of the slot to be consistent with the direction of the clamping rod. The movable clamping plate moves outward to release the wet wipe substrate. Clamping rod assembly B enters the clamping plate assembly from one side and clamps the wet wipe substrate that has been filled with liquid. The wet wipe substrate is sent into the discharge conveyor. At the same time, clamping rod assembly B moves to the other side of the clamping plate assembly. ⑦ Following steps ③, ④, and ⑤ above, re-feed the dry wet wipe substrate into the clamping assembly and complete the wet wipe liquid addition operation.

[0012] The beneficial technical effects of this invention are: The liquid-adding equipment and process have a flip-type clamp in the middle of the frame. The clamping plate assembly of this clamp can clamp or release the wet wipe substrate. The wet wipe substrate on the feeding conveyor is picked up by a bidirectional gripping device and placed into the clamping plate assembly. The liquid-adding mechanism above adds liquid to it. The clamping plate assembly can rotate freely under the drive of a motor, allowing for liquid addition from both sides, which improves the uniformity and penetration of liquid addition to the wet wipe substrate. After liquid addition is completed, the bidirectional gripping device removes it and places it into the discharge conveyor for the next process. This liquid-adding equipment and process can add liquid to the wet wipe substrate after folding, avoiding the problem of wet strips sticking to the conveyor and causing strip deformation. This improves the forming effect and appearance of the product, which is conducive to enhancing market competitiveness. Attached Figure Description

[0015] Example 1, referring to Figures 1-11 in the specification, is a fully automatic wet wipe liquid dispensing device. The device includes a feeding conveyor installed on one side of the frame, a discharging conveyor installed on the other side of the frame, a bidirectional gripping device installed between the two conveyors, a flipping clamp installed in the middle of the frame, and a liquid dispensing mechanism installed above the wet wipe substrate clamp. The two end plates of the flip-type clamp are fixed to the upper crossbeam of the frame. A clamping plate support assembly is rotatably connected to the lower inner side of the end plates via a rotating shaft. The inner plate of this clamping plate support assembly is fixedly connected to the inner end of a wheel axle. A driven wheel is mounted on the outer end of the wheel axle, and the rotation of the driven wheel drives the clamping plate support assembly to rotate. A fixed seat is provided on one side of the inner plate, and a movable seat is connected to the other side via a transverse slide rod. A cylinder A is installed inside the fixed seat to drive the movable seat to move along the transverse slide rod. A clamping plate assembly connects the fixed seat and the movable seat. The fixed clamping plate of the clamping plate assembly is connected between the two fixed seats via a support rod, and the movable clamping plate is connected between the two movable seats via a support rod. Both the outer surfaces of the fixed seat and the movable seat are provided with… The connector and support rod are fixedly fitted inside the connector. The inner sides of both the fixed clamping plate and the movable clamping plate are provided with several slots at equal intervals along the width direction. A drive wheel is installed on the upper part of the end plate. A belt is fitted between the drive wheel and the driven wheel. The two drive wheels are connected by a synchronous shaft. A drive source for driving the drive wheel is installed on one end plate. The drive source is a motor. The motor drives the drive wheel on one side to rotate through the belt. Under the action of the synchronous shaft, the drive wheels on both sides rotate synchronously, driving the two driven wheels to rotate synchronously. Therefore, the clamping plate assembly can be driven to rotate synchronously from both ends. The clamping plate assembly has good stability in clamping the wet wipe substrate, ensuring that the wet wipe substrate does not deform as a whole and there is no shaking or misalignment between each layer.

[0016] A horizontal receiving plate is located below the clamping plate assembly. The fixed clamping plate and the movable clamping plate cannot apply excessive clamping force to the wet wipe substrate. In order to avoid the liquid not being able to fully enter the wet wipe substrate, there is a risk that the wet wipe substrate will fall due to the increased weight of the liquid. The horizontal receiving plate is used to catch the wet wipe substrate when it falls, and plays a protective role. A vertical drive assembly is installed at the lower end of the end plate. The horizontal receiving plate is driven to move up and down through two drive assemblies. Therefore, the height of the horizontal receiving plate can be adjusted as needed. The drive assembly includes a guide rod fixedly connected to the lower end of the end plate. The horizontal receiving plate is slidably connected to the guide rod through a sliding seat. A cylinder E is provided at the lower end of the guide rod to drive the sliding seat to move up and down.

[0017] The bidirectional gripping device includes two symmetrically arranged cross-shaped single-belt machines connected by a synchronous shaft B. A single power source enables the two single-belt machines to rotate synchronously. For the principle of the cross-shaped single-belt machine, please refer to the applicant's previous patent application, patent number CN2021204250834. A bidirectional gripping mechanism is installed between the upper ends of the two vertical support plates of the two cross-shaped single-belt machines. Each end of the mechanism is provided with a seat plate. Between the two seat plates, clamping rod assembly A and clamping rod assembly B are installed. Clamping rod assembly A and clamping rod assembly B are identical and symmetrically arranged. The cross-shaped single-belt machines drive the two clamping rod assemblies to move laterally or vertically.

[0018] The clamping rod assembly A includes a lower crossbar fixedly connected between two base plates and an upper crossbar slidably mounted between the base plates via a vertical slide bar. A cylinder B is provided on the base plate to drive the upper crossbar to move up and down. Several upper clamping rods are vertically arranged on the outer side of the upper crossbar, and several lower clamping rods are vertically arranged on the outer side of the lower crossbar. The spacing between the clamping rods is the same. Under the action of the cylinder B, the upper and lower crossbars can move towards or away from each other to achieve the clamping or releasing action of the clamping plates. The upper or lower clamping rods in the two clamping rod assemblies are in opposite directions, and the positions of the upper and lower clamping rods correspond to the positions of the slots, realizing the bidirectional gripping or releasing action of the bidirectional gripping device.

[0019] The liquid dispensing mechanism includes a cross-shaped single-belt motor B. A cylinder C is vertically mounted on the inner end of the horizontal support plate of the cross-shaped single-belt motor B. A nozzle assembly is mounted on the lower end of the piston rod of the cylinder C. The cross-shaped single-belt motor B drives the nozzle assembly to correspond with the wet wipe substrate in the clamping plate assembly and drives it to move along the length of the wet wipe substrate to dispense liquid. The cylinder C is used to adjust the spray height of the nozzle assembly.

[0020] The nozzle assembly includes a square housing and a cylinder D. A liquid inlet pipe is located on one side of the square housing. The square housing is slidably mounted below the cylinder D via a vertical slide column, and is driven to move up and down by the cylinder D. Several spray holes are evenly distributed on the bottom surface of the square housing. A sealing plate is located inside the housing above the spray holes. The lower end of the vertical slide column is fixedly connected to the sealing plate. The cylinder D drives the square housing to move up and down along the vertical slide column, causing the sealing plate to fit or separate from the spray holes, forming a terminal switch within the nozzle. The closing chamber height is controlled at 1mm, resulting in minimal liquid retention in the dispensing head. Simultaneously, the surface tension of water ensures that no liquid drips out after the dispensing head is closed, preventing residual liquid from continuing to flow out of the nozzle after dispensing. A sealing gasket is provided around the spray holes. The edge of the sealing plate can be horizontally pressed against the surface of the sealing gasket. The sealing ring improves the sealing effect of the sealing plate on the spray holes, preventing leakage after dispensing and avoiding affecting the accuracy of liquid dispensing to the wet wipe substrate due to leakage.

[0021] Nozzle Technology: The nozzle assembly uses a multi-hole nozzle, which safely covers the width of the folded fabric strip in the spray area. The nozzle housing is replaceable and can be adapted to fabric strips of different thicknesses. Cylinder D drives the square housing to move up and down along the vertical slide column, so that the sealing plate can be attached to or separated from the spray hole, forming a terminal switch inside the nozzle. The height of the closing chamber is controlled at 1mm, and very little liquid remains in the filling head. At the same time, the surface tension of water ensures that no liquid drips out after the filling head is closed, avoiding the phenomenon of residual liquid continuing to flow out of the nozzle after filling is completed.

[0022] The feeding conveyor includes several belt conveyor components arranged side by side, with a certain gap between the belt conveyor components. The discharging conveyor is a roller conveyor, with a certain gap between the conveying rollers of the roller conveyor. The clamping rod of the bidirectional gripping device can clamp the wet wipe substrate from the gap or let the wet wipe substrate down from the gap.

[0023] Example 2, see appendix to the instruction manual. Figure 1-10 A liquid dispensing process method for a fully automatic wet wipe dispensing device, comprising the fully automatic wet wipe dispensing device described in Example 1, including the following steps: ① Fold the dry wet wipe substrate with a folding device to form a strip substrate with a certain thickness, and then put it on the feeding conveyor and send it to one side of the frame; ②The two clamping rod assemblies in the bidirectional gripping device move toward the wet wipe substrate under the drive of the cross-shaped single-belt mech, and clamp the wet wipe substrate through the clamping rod assembly A; ③ The movable clamping plate in the flip-type clamping plate assembly moves outward, so that sufficient clamping space is formed between the fixed clamping plate and the movable clamping plate. Then the clamping plate assembly rotates freely so that the direction of the slot on the clamping plate is consistent with the direction of the clamping rod in the clamping rod assembly. ④ The clamping rod assembly A clamps the wet wipe substrate into the clamping space of the clamping plate assembly. The movable clamping plate moves inward to clamp the wet wipe substrate. The upper clamping rod and the lower clamping rod enter the slot to avoid being clamped by the two fixed clamping plates and the movable clamping plate. Then the clamping rod assembly A leaves the clamping plate assembly to complete the feeding. ⑤ The clamping plate assembly rotates freely to adjust the unclamped surface of the wet wipe substrate to a horizontal state. The nozzle assembly of the liquid dispensing mechanism moves to above one end of the wet wipe substrate and then sprays liquid while moving to the other end to add liquid. After the liquid is added to one side of the wet wipe substrate, the clamping plate assembly rotates freely to adjust the other side of the wet wipe substrate to the top to add liquid, ensuring that the liquid fully and evenly penetrates into the cloth strip substrate. ⑥ Clamping rod assembly A clamps the new wet wipe substrate according to step ②. Then the clamping plate assembly rotates freely to readjust the direction of the slot to be consistent with the direction of the clamping rod. The movable clamping plate moves outward to release the wet wipe substrate. Clamping rod assembly B enters the clamping plate assembly from one side and clamps the wet wipe substrate that has been filled with liquid. The wet wipe substrate is sent into the discharge conveyor. At the same time, clamping rod assembly B moves to the other side of the clamping plate assembly. ⑦ Following steps ③, ④, and ⑤ above, re-feed the dry wet wipe substrate into the clamping assembly and complete the wet wipe liquid addition operation; ⑧ The piston pump is equipped with servo drive control. The piston pump has high efficiency, good suction performance, and stable water flow parameters. The water flow rate ejected by the equipment remains constant under different pressures. ⑨ Liquid pump drive and control: The piston pump is driven and controlled by a servo motor. Compared with cylinders or other drive methods, the speed of the servo motor drive is controllable and the accuracy is very accurate, ensuring accurate water pumping and higher liquid addition precision. ⑩ Filling head actuator process: It adopts a servo-driven single-belt module. The piston pump has a very precise water pumping volume, but there is a non-linear characteristic at the moment of opening and closing. The servo motor has the characteristics of controllable speed and precise position, which can make up for the non-linear characteristic of the piston pump at the moment of opening and closing, ensuring that the liquid filling volume at the moment of opening and closing is consistent with the liquid filling during normal operation, thereby ensuring the overall uniformity of liquid filling of the fabric strip.
