Description

Technical Field

[0001] The invention relates to the technical field of combs, in particular to a continuous automatic cleaning machine for combs used in viscose fiber production and an assembly method and an operation method thereof. Background Art

[0002] The comb is an important device in the fiber production process. It plays a key role in fiber production. It is mainly used for combing and sorting fibers to ensure that the fibers can maintain good condition and quality in subsequent production links. Its structure and performance directly affect the efficiency of fiber production and product quality. It is an indispensable part of fiber production equipment.

[0003] At present, in the field of fiber production, the cleaning of combs is mainly done by manual cleaning. This method has exposed many problems when facing the increase in the variety of chemical fiber products and the expansion of production scale. Due to the low efficiency of manual cleaning, as the number of combs increases, the cleaning workload increases significantly, resulting in the overall cleaning efficiency being inevitably lower. At the same time, manual cleaning requires a lot of manpower, which increases the labor intensity. In addition, the hazards of chemicals used in the cleaning process to human health are becoming increasingly prominent, posing a potential threat to the health of operators.

[0004] However, the existing cleaning methods cannot meet the fiber production companies' needs for efficient and continuous cleaning of combs. On the one hand, the low efficiency of manual cleaning seriously affects the overall process of fiber production, increases the production cycle, and reduces production efficiency; on the other hand, the high labor intensity and the harm of chemicals to the human body do not meet the modern production companies' requirements for humanization and safety. In addition, with people's increasing attention to the quality and quality of chemical fiber products, the cleanliness of the comb is directly related to the quality of fiber products, and the existing manual cleaning method can hardly ensure that the cleaning effect of the comb is stable and up to standard. Summary of the invention

[0005] The object of the present invention is to provide a continuous automatic cleaning machine for a comb for viscose fiber production and an assembly method and an operation method thereof, aiming to solve the problems in the prior art that the comb for viscose fiber production relies on manual cleaning, resulting in low cleaning efficiency, high labor intensity, chemical hazards to human health, and inability to meet the needs of efficient and continuous cleaning.

[0006] To achieve the above object, the present invention adopts the following technical solution: A continuous automatic cleaning machine for a comb for viscose fiber production comprises a frame, wherein a rough washing tank, a fine washing tank, a blow-drying tank and a down-line tank are respectively arranged inside the frame, a discharge port, six guide holes and four liquid level limiting holes are respectively opened on the inner wall of the frame, a first hydraulic reversing valve and a second hydraulic reversing valve are fixedly connected to the inner wall of each of the liquid level limiting holes and the inner wall of the guide hole, two guide grooves are opened on the outer surface of the frame, a plurality of mounting holes and four first mounting positioning grooves are respectively opened on the upper surface of the frame, a first intermediate bracket, a second intermediate bracket, a third intermediate bracket and a top cover plate are respectively arranged above the frame, four first mounting positioning holes are opened on the upper surface of the first intermediate bracket, four second mounting positioning holes are opened on the upper surface of the second intermediate bracket and the upper surface of the third intermediate bracket, and the third intermediate bracket is provided with a plurality of mounting holes and a plurality of mounting holes. Four first threaded positioning rods are arranged inside the bracket, and two second threaded positioning rods are arranged inside the second intermediate bracket, wherein the outer surfaces of two of the first threaded positioning rods are respectively threadedly connected to the inner walls of two of the first mounting positioning grooves, the inner walls of two of the first mounting positioning holes and the inner walls of four of the second mounting positioning holes, and the outer surfaces of the other two of the first threaded positioning rods are threadedly connected to the inner walls of the other four second mounting positioning holes, and the outer surface of each of the second threaded positioning rods is threadedly connected to the inner walls of the other two first mounting positioning grooves, the inner walls of the other two first mounting positioning holes and the inner walls of the other two second mounting positioning holes, the first intermediate bracket is embedded in the interior of the frame through the bottom convex plate, the outer surface of the top cover plate is clamped with the interior of the third intermediate bracket, and a material receiving tray is fixedly connected to the back of the frame.

[0007] A method for assembling a continuous automatic cleaning machine for a combing device for viscose fiber production comprises the following steps: S6-1: First, a casting process or welding process is used to form a prototype of the frame, and a mechanical processing method is used to process the corresponding joint surface, holes and guide grooves. Then, a rough washing brush, a fine washing brush and a blow-drying brush are made. These brushes are basically the same in appearance and shape, but the difference is the hardness, length and density of the bristles. S6-2: Then make the parts of the transition layer of the fine washing tank, and make them fully inlaid and assembled with the fine washing tank, and then assemble the frame, brush and the parts of the transition layer of the fine washing tank together; S6-3: Then, a connecting device for receiving the upper brush is processed, a movable guide rod is processed, the movable guide rod is connected to the second intermediate bracket, and the upper brush is installed; S6-4: Make a nozzle assembly, which must have a series of nozzle holes. Then make a third intermediate bracket, which is mainly used to support, install and fix the nozzle assembly. Assemble the nozzle assembly and the third intermediate bracket 18 together. S6-5: manufacturing a top cover plate, and assembling the top cover plate onto the third intermediate bracket; S6-6: Perform final overall assembly, including auxiliary work such as positioning drilling, calibration, bearing installation and lubrication.

[0008] A method for operating a continuous automatic cleaning machine for a combing device for viscose fiber production comprises the following steps: S7-1: Before cleaning, the external cleaning liquid input pipeline is connected to the high-pressure cleaning liquid nozzle through the water inlet pipe, and the combing device is placed on the movable guide rod at the entrance of the frame. The first photoelectric sensor detects and transmits a signal to the PLC programmable controller. The PLC programmable controller starts the three stepping motors on the left side of the frame through the driver according to the program, drives the brush shaft through the transmission, and makes the brush attachment run to brush off the large particles on the comb teeth of the combing device. At the same time, the power push rod drives the arc push plate to move left, ready to push the combing device to the rough washing area; S7-2: The power push rod pushes the comb to the rough washing area, and the rough washing starts. The stepper motor drives the three first brush shafts through the transmission belt to make the rough brushes rotate and wash the comb. The external cleaning liquid pipeline connected to the high-pressure cleaning liquid nozzle inputs the cleaning liquid into the high-pressure cleaning liquid nozzle through the water inlet pipe. The nozzle sprays the liquid, and the upper and lower rough washing brushes cooperate to clean the upper and lower parts of the comb respectively. After cleaning, the liquid flows into the rough washing tank, and the solid sinks to the bottom of the rough washing tank. Then the power push rod returns to its original position, ready to push the next comb; S7-3: The power push rod reciprocates, and the rear combing device squeezes the front one into the fine washing area. The stepper motor drives the three second brush shafts through the transmission, and the fine bristles rotate at high speed in a triangular shape. The fine bristles at the bottom are thrown into the cleaning liquid in the fine washing tank to wash the lower half of the combing device, and the high-pressure cleaning liquid nozzle at the top sprays liquid to wash the upper half, further removing dirt and finely cleaning the combing device; S7-4: The comb is squeezed to the drying area, and the stepper motor drives the two third brush shafts through transmission. The air compressor supplies high-pressure air, which is sprayed to the comb through the high-pressure air nozzle. The third brush shaft drives the cleaning bristles to rotate, taking away the water stains, which are discharged through the guide holes and guide grooves. The high-pressure air and the cleaning bristles work together to dry the comb without residue, preparing for offline; S7-5: The cleaned and dried combs are pushed to the offline area, and the high-pressure air nozzle continues to spray air, and the combs slide out of the cleaning machine along the tail of the movable guide rod. When there are no combs in the rough washing area but there are some in the fine washing area, the power push rod pushes the combs in the fine washing area to the drying area and the offline area through the arc push plate, removes the remaining combs, and completes the cleaning cycle.

[0009] The beneficial effects of the present invention are: When the present invention is used, the cleaning machine realizes deep cleaning of the comb through a multi-stage and multi-mode cleaning process. When the comb enters the rough cleaning area, the coarse bristles cooperate with the cleaning liquid sprayed by the high-pressure cleaning liquid nozzle to scrub the surface and gaps of the comb, effectively removing stubborn dirt. When the comb enters the fine cleaning area, the fine bristles rotate at high speed to further remove residual impurities, ensuring that all parts of the comb meet high cleanliness standards. When the comb enters the drying area, the high-pressure air and the rotating cleaning bristles work together to not only remove water stains but also take away fine residues, thereby improving the quality of viscose fiber production and reducing product defects caused by unclean combs. 2. When the present invention is in use, the entire process is precisely controlled by the PLC controller according to the preset program and the feedback signal of the first photoelectric sensor. When there is no combing device in the rough washing area but there is still a combing device in the fine washing area, the power push rod can automatically adjust the working mode and push the combing device in the fine washing area to the subsequent areas in turn to ensure the continuity of the cleaning process. It not only reduces manual intervention, but also improves cleaning efficiency and reduces labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Embodiment 5, on the basis of embodiment 4, as Figure 1-13As shown, the inner wall of the second intermediate bracket 23 is clamped with two movable guide rods 22, and the outer surface of each movable guide rod 22 is fixedly connected to two base frames 53, and the outer surface of each base frame 53 is clamped with the inner part of the mounting hole 39, and the outer surface of each movable guide rod 22 is threadedly connected to two fastening nuts 33, and the inner wall of the second intermediate bracket 23 is respectively fixedly connected with three first photoelectric sensors 21 and two power push rods 20, and the telescopic end of each power push rod 20 is fixedly connected with an arc push plate 56, and a plurality of combing devices 19 are arranged above the two movable guide rods 22, and the outer surface of each arc push plate 56 The surfaces are in contact with the outer surface of a combing device 19 close to the arc-shaped push plate 56, and the front of the frame 1 is fixedly connected with a PLC programmable controller 4 and a driver 3, respectively.

The PLC programmable controller 4 is electrically connected to the stepping motor 10, the air compressor 12, the first photoelectric sensor 21, the second photoelectric sensor 63, the power push rod 20, the liquid level sensor 64 and the driver 3 through wires.

[0021] In this embodiment, the two movable guide rods 22 clamped on the inner wall of the second intermediate bracket 23 are clamped on the mounting holes 39 through the base frame 53 and fixed by the fastening nuts 33, so as to stably support the combing device 19. The three first photoelectric sensors 21 on the inner wall of the second intermediate bracket 23 are responsible for detecting the position state of the combing device 19, such as detecting the entry of the combing device 19 at the entrance and detecting whether the combing device 19 is in place in each cleaning area. After receiving the instruction of the PLC programmable controller 4, the two power push rods 20 push the combing device 19 to move between different cleaning areas through the arc-shaped push plate 56 at the telescopic end. The PLC programmable controller 4 and the drive push rods 20 on the front of the frame 1 are used to detect the position of the combing device 19. The actuator 3 constitutes the core of the control system of the entire cleaning machine. The PLC programmable controller 4 is electrically connected to the stepper motor 10, the air compressor 12, the first photoelectric sensor 21, the power push rod 20 and the driver 3 through wires. According to the preset program and the signal fed back by the first photoelectric sensor 21, each component is precisely controlled. For example, when the first photoelectric sensor 21 detects that the combing device 19 enters the entrance position, the PLC programmable controller 4 starts the stepper motor 10 to rotate the brush, and controls the power push rod 20 to push the combing device 19 into the rough washing area. In each cleaning area, the spraying of cleaning liquid and high-pressure air and the rotation speed of the brush are controlled according to the detection signal.

[0022] Working principle: First, the external cleaning liquid input pipeline is connected to the high-pressure cleaning liquid nozzle 16 through the water inlet pipe 17, and the cleaning liquid is added to the rough washing tank 45 and the fine washing tank 44 through the high-pressure cleaning liquid nozzle 16. Note: The combing device 19 enters the V-shaped groove of the second intermediate bracket 23 under the operation of tools such as robots (which are prior arts, not shown in the figure). The bottom edge diameter of this V-shaped groove is smaller than the top edge diameter, so that when the combing device 19 is pushed, it can enter the inside of the frame 1 one by one. When the first photoelectric sensor 21 detects that the combing device 19 is in place, the first photoelectric sensor 21 will react for five seconds. The specific time needs to be set according to the actual situation. The power push rod 20 on the second intermediate bracket 23 drives the arc push plate 56 to start to slowly move at a certain speed. Move to the left to prepare for pushing the combing device 19 away from the entrance and entering the rough washing area. When the second photoelectric sensor 63 in the rough washing area detects the combing device 19, it will transmit a signal to the PLC programmable controller 4. The PLC programmable controller 4 controls the stepper motor 10 outside the rough washing area with the help of a driver according to a preset program. The stepper motor 10 outside the rough washing area drives the three first brush shafts 27 to rotate inside six of the bearings 38 through the second transmission belt 8 and the third transmission belt 6. The three first brush shafts 27 drive the coarse brushes 37 to rotate at high speed. The coarse washing brushes arranged in a triangular shape enter the working state and first brush the surface of the combing device 19 comprehensively. At this time, the external cleaning liquid pipeline connected to the high-pressure cleaning liquid nozzle 16 passes through the water inlet pipe 17. The cleaning liquid is input into the high-pressure cleaning liquid nozzle 16, and the high-pressure cleaning liquid nozzle 16 then sprays the cleaning liquid onto the comb 19 through the bottom nozzle 50. The upper coarse brush carries the sprayed cleaning liquid and rotates continuously to wash the upper half of the comb 19, including the comb rod and the comb tooth ring, etc. The lower coarse brush uses the power generated by the rotation to assist in evenly distributing the cleaning liquid sprayed onto the comb 19, washing the left and right surfaces of the comb teeth and the gaps between the comb teeth, that is, cleaning the lower half of the comb 19. In this process, the cleaning liquid after cleaning the comb 19 falls into the coarse washing tank 45 and is used together with the original cleaning liquid in the coarse washing tank 45, while the solid particles washed down are deposited at the bottom of the coarse washing tank 45. At the same time, the power push rod 20 quickly returns to its original position. The first position is ready to push the next combing device 19 into the rough washing area. In the fine washing stage, as the power push rod 20 continuously reciprocates, the rear combing device 19 pushes the front combing device 19 to enter the fine washing area. When the second photoelectric sensor 63 inside the fine washing area detects the combing device 19, it will transmit the signal to the PLC programmable controller 4. The PLC programmable controller 4 drives the stepper motor 10 outside the fine washing area with the help of the driver 3 according to the preset program. The stepper motor 10 outside the fine washing area drives the three second brush shafts 28 through the fourth transmission belt 29 and the fifth transmission belt 7 to rotate inside the six bearings 38. In the fine washing area, the fine bristles 35 driven by the brush shaft are driven by the stepper motor 10 to rotate at high speed in a herringbone shape up and down.The two fine bristles 35 at the bottom throw the cleaning liquid in the fine washing tank 44 onto the combing device 19, and wash the lower part of the combing device 19, including the gaps between the comb teeth and the left and right sides. The fine bristles 35 at the top also throw the cleaning liquid sprayed from the high-pressure cleaning liquid nozzle 16 onto the upper part of the combing device 19. At the same time, the high-pressure cleaning liquid nozzle 16 also sprays part of the cleaning liquid onto the combing device 19, and washes the upper part of the combing device 19 with high-speed rotation. In this way, the dirt on the surface of the combing device 19 is further cleaned, and the impurities remaining on the surface of the combing device 19 are rinsed clean. Some smaller solid impurities fall directly into the fine washing tank 44. In the drying stage, the combing device 19 is squeezed into the drying area, and the second photoelectric sensor 63 inside the drying area When the combing device 19 is detected, a signal is transmitted to the PLC programmable controller 4 in this area. The PLC programmable controller 4 drives the stepper motor 10 outside the drying area with the help of the driver 3 according to the preset program. The stepper motor 10 drives the two third brush shafts 31 through the sixth transmission belt 9 to rotate inside the other two bearings 38. The high-pressure air nozzle 14 above sprays high-pressure air to the surface of the combing device 19 through the nozzle 50 via the air compressed by the air compressor 12. At the same time, the cleaning bristles 36 driven by the third brush shaft 31 are driven by the stepper motor 10 to rotate at high speed up and down. The high-speed rotating cleaning bristles 36 take away the excess water stains on the combing device 19, and the water stains taken away and thrown off from the surface of the combing device 19 are removed by the cleaning bristles 36. The guide holes 30 and the guide grooves 24 in the empty groove are timely guided away, and the first hydraulic reversing valve 61 and the second hydraulic reversing valve 62 at the bottom of the rough washing area, the fine washing area and the blow-drying area can detect the liquid level of the cleaning liquid. After the first hydraulic reversing valve 61 and the second hydraulic reversing valve 62 detect the relevant liquid level, the signal is transmitted to the PLC programmable controller 4 through the wire, and the PLC programmable controller 4 performs logical operations and obtains the results. According to the logical operation results, the first hydraulic reversing valve 61 and the second hydraulic reversing valve 62 are controlled to be opened, closed or pressure-maintained, so that the liquid level is always in a reasonable working range. Through the above process, the high-pressure air and the cleaning bristles 36 work together to blow and brush the water stains and fine residues on each surface of the combing device 19 to ensure the combing The surfaces of the comb 19 are clean and dry.
