Description

Technical Field

[0001] The present invention relates to the technical field of mold cleaning devices, and particularly to an automatic mold base cleaning device. Background Art

[0002] When producing optical fibers, in order to prevent the surface of the optical fiber from being damaged by humid gas and external force, and at the same time improve the micro-bending resistance of the optical fiber and reduce the micro-bending additional loss of the optical fiber, it is necessary to add a coating layer to the optical fiber through a mold. The mold is installed in the mold base. Each time the wire drawing ends or the wire breaks during the wire drawing process, the mold needs to be removed, and the mold and the mold base need to be cleaned again. The cleaning degree of the mold base directly determines the quality of the coating layer on the surface of the optical fiber, and thus affects the performance of the optical fiber. At present, it mainly relies on manual use of clean paper dipped in cleaning liquid for cleaning. Since there is coating on the inner wall of the base and there are grooves inside, only one finger can be inserted into the mold base for manual cleaning, which is time-consuming and laborious, with low efficiency; it is easy to cause waste of cleaning liquid and clean paper; and the situation of unclean cleaning often occurs.

[0028] To enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention.

[0029] Please refer to Figures 1-5 as shown in the figure, an automatic die base cleaning device includes:

[0030] a bracket 1;

[0031] a brush assembly 2, which is fixedly installed on the bracket 1 and has a lateral installation distance from the bracket 1. The brush assembly 2 moves in and out of the die base 9 to be cleaned along the length direction of the bracket 1 under the drive of a first drive assembly 4, and rotates axially along itself within the die base 9 to be cleaned under the drive of a second drive assembly 5, realizing the automatic cleaning of the die base 9 to be cleaned;

[0032] a cleaning liquid storage mechanism 3, which includes a recovery tank 31 for recovering the cleaning liquid and a cleaning tank 32 movably arranged in the recovery tank 31. The cleaning tank 32 is located directly below the brush assembly 2;

[0033] a PLC control system (not shown in the figure), which is used to control the operation of the first drive assembly 4 and the second drive assembly 5.

[0034] In the above embodiment, by installing the brush assembly 2 for cleaning the die base 9 on the bracket 1, the brush assembly 2 can move in and out of the die base 9 to be cleaned and rotate axially along itself under the action of the first drive assembly 4 and the second drive assembly 5, and the working process of the first drive assembly 4 and the second drive assembly 5 is controlled by the PLC control system, thereby realizing the cleaning work of the die base 9 to be cleaned; by arranging a cleaning liquid storage structure directly below the brush assembly 2, the brush assembly 2 can be cleaned, and the waste liquid for cleaning the die base 9 can be recycled.

[0035] It should be noted that the above-mentioned bracket 1 serves as the installation platform for the brush assembly 2, the first drive assembly 4, the second drive assembly 5, and the cleaning liquid storage mechanism 3. As long as it can ensure the normal operation of the above-mentioned components, the specific structure of the bracket 1 can be in various forms. Exemplarily, Figure 1 as shown in the figure, the bracket 1 includes a base 11, a slide rail 12 perpendicular to the base 11, a slider slidably installed on the slide rail 12, and a mounting plate 13 horizontally installed on one side of the slider.

[0036] Among them, the base 11 is used for installing the cleaning liquid storage mechanism 3, the mounting plate 13 is used for fixedly installing the brush assembly 2, and the slide rail 12 serves as the track for the slider to slide.

[0037] Such as Figure 1 and 3As shown in the figure, the first driving component 4 includes a cylinder 41 fixedly installed at the upper end of the slide rail 12 and a position sensor disposed on the outer wall of the cylinder 41 for sensing the telescopic length of the piston rod 42 of the cylinder 41. The lower part of the piston rod 42 is fixedly connected to the upper end surface of the mounting plate 13, and the position sensor is electrically connected to the PLC control system.

[0038] It should be noted that the number of the above-mentioned position sensors can be set according to actual operation needs to facilitate controlling the working process of the cylinder 41; in addition, in this embodiment, the cylinder 41 used is a single-piston-rod cylinder 41. As Figure 1 shown, the cylinder body of the single-piston-rod cylinder 41 is fixedly installed on the upper part of the slide rail 12 along the length direction of the slide rail 12 through a connecting ear, and the lower end of the piston rod 42 can be connected to the slider or the mounting plate 13, and in this embodiment, it is connected to the mounting plate 13. Obviously, other similar cylinders 41 can also complete the above reciprocating motion, and the model of the cylinder 41 is not limited herein.

[0039] As Figure 1 and 2 shown, the brush assembly 2 includes a central tube 21 for storing cleaning liquid, a spray head 22 disposed at the lower end of the central tube 21, a sleeve 23 rotatably sleeved outside the central tube 21, and brushes 24 distributed on the outer wall of the sleeve 23. The central tube 21 is vertically fixed to the lower end surface of one end of the mounting plate 13 away from the slide rail 12.

[0040] The second driving component 5 includes a motor 51 installed on the upper end surface of the mounting plate 13. The motor 51 is electrically connected to the PLC control system. The output shaft of the motor 51 passes through the lower end surface of the mounting plate 13, and a driving gear 52 is fixedly sleeved on the lower part of the output shaft. A driven gear 53 is sleeved at the same height as the driving gear 52 outside the sleeve 23, and the driving gear 52 drives the driven gear 53 to rotate through a belt.

[0041] It should be noted that the cleaning liquid is stored in the above-mentioned central tube 21. Considering that the rotation of the central tube 21 is likely to cause the cleaning liquid to rotate accordingly, which is not conducive to the spraying of the cleaning liquid from the spray head 22. Therefore, in this embodiment, the central tube 21 is designed to be fixedly connected.

[0042] Since the actual die holder 9 has grooves inside, in order to adapt to the grooves, the brush 24 can include a long brush section and a short brush section. The long brush section is used to clean the parts with a larger diameter, and the short brush section is used to clean the parts with a smaller diameter; of course, the brush 24 can also be a mixture of long brushes and short brushes. The brush 24 can be fully distributed on the outside of the sleeve 23 or arranged at intervals on the outside of the sleeve 23; similarly, the long brush section and the short brush section can be arranged up and down or at intervals.

[0043] As Figure 1, Exemplarily, the cleaning tank 32 includes a cleaning chamber for containing cleaning liquid and a squeezing chamber located above the cleaning chamber for squeezing the brush 24. A first liquid level sensor (not shown in the figure) and a second liquid level sensor (not shown in the figure) are respectively provided on the inner wall of the recovery tank 31 and the cleaning chamber. Both the first liquid level sensor and the second liquid level sensor are electrically connected to the PLC control system.

[0044] The squeezing chamber is in the shape of a conical barrel, the inner diameter of its upper opening is smaller than the outer diameter of the brush tube formed by the brush 24 and the sleeve 23, and larger than the outer diameter of the sleeve 23.

[0045] It should be noted that in actual operation, the mold base 9 can be fixed on the upper part of the cleaning chamber through a mold base 9 fixing frame (not shown in the figure), and the relative position of the mold base 9 and the cleaning tank 32 can be adjusted to ensure that the central axes of the mold base 9 and the cleaning tank 32 coincide, so as to ensure that the brush 24 can smoothly enter and exit the mold base 9 and the cleaning tank 32;

[0046] Since the outer diameter of the brush tube is smaller than the inner diameter of the upper opening of the squeezing chamber, when it enters the inside, the brush 24 will be squeezed, and the cleaning liquid and stains on the brush 24 will be squeezed out and flow into the recovery tank 31 from the outer wall of the slope of the squeezing chamber; after the brush 24 enters the cleaning chamber and dips into the clean cleaning liquid, when it leaves the squeezing chamber, the cleaning liquid and stains are squeezed out. This process, to a certain extent, completes the self-cleaning of the brush 24, and can ensure to the greatest extent that a relatively clean brush 24 is used to clean the mold base 9, improving the cleaning efficiency of the mold base 9.

[0047] In order to prevent the waste liquid flowing out from the lower part from entering the cleaning chamber when cleaning the mold base 9, the inner diameter of the squeezing chamber should be smaller than the inner diameter of the mold base 9, and the lower part of the mold base 9 should be slightly higher than the upper part of the squeezing chamber, so that most of the waste liquid flowing out from the lower part of the mold base 9 will flow into the recovery tank 31 along the slope of the conical barrel-shaped squeezing chamber.

[0048] The functions of the above-mentioned first liquid level device and second liquid level device are to monitor the liquid levels in the recovery tank 31 and the cleaning chamber, prevent the waste liquid in the recovery tank 31 from overflowing and the cleaning liquid in the cleaning chamber from being insufficient, and transmit the monitoring signals to the PLC control system for timely adjustment to ensure the normal progress of the cleaning work.

[0049] As Figure 4 and 5 shown, in order to improve the utilization rate of the cleaning liquid, a waste liquid treatment tank 6 is also included. A first water pump 7 and a second water pump 8 are respectively connected to the outside of the waste liquid treatment tank 6 and the recovery tank 31. The first water pump 7 is respectively connected to the cleaning tank 32 and the upper opening of the central pipe 21 through pipelines, and the second water pump 8 is connected to the waste liquid treatment tank 6 through a pipeline; both the first water pump 7 and the second water pump 8 are electrically connected to the PLC control system.

[0050] It can be understood that when there is too much waste liquid in the recovery tank 31, the PLC control system controls the second water pump 8 to pump the waste liquid into the waste liquid treatment tank 6; when the cleaning liquid in the cleaning tank 32 is insufficient or the brush 24 enters and exits the die holder 9, the PLC control system controls the first water pump 7 to supplement the cleaning liquid or spray the cleaning liquid from the nozzle 22.

[0051] As Figure 5 shown, the waste liquid treatment tank 6 is provided with a first baffle 61 and a third baffle 63 at intervals. The first baffle 61 is higher than the third baffle 63, and divides the waste liquid treatment tank 6 into a first cavity 611, a second cavity 621 and a third cavity 631 with non - communicating bottoms.

[0052] A second baffle 62 is provided between the first baffle 61 and the third baffle 63. The second baffle 62 is suspended and fixed on the inner wall of the cleaning tank 32, and the lower end surface height of the second baffle 62 is lower than its own height, and the upper end surface height is greater than the height of the first baffle 61.

[0053] It can be understood that when the waste liquid is transported from the recovery tank 31 to the first cavity 611, the impurities with larger density in the waste liquid will precipitate in the first cavity 611. When the waste liquid in the first cavity 611 overflows, the relatively clean waste liquid on the upper layer enters the second cavity 621. At this time, the impurities with smaller density floating on the upper layer of the waste liquid will be blocked by the second baffle 62 for further cleaning of the waste liquid. When the waste liquid overflows from the second cavity 621 and enters the third cavity 631, the waste liquid at this time basically does not contain floating impurities and sediment - type impurities, that is, it can be used as the cleaning liquid for secondary use.

[0054] Of course, in order to avoid as little floating matter as possible entering the third cavity 631, the second baffle 62 can be arranged close to the third baffle 63.

[0055] The working process of this device:

[0056] It should be noted that in order to facilitate the control of the working process of the brush 24, a first position sensor 43, a second position sensor 44 and a third position sensor 45 are arranged outside the single - piston - rod 42 cylinder 41, corresponding to the three positions where the cylinder 41 pushes the nozzle 22 into the upper part of the die holder 9, leaves the lower part of the die holder 9, and the brush 24 is completely immersed in the cleaning tank 32 respectively.

[0057] When the die holder 9 needs to be cleaned, the die holder 9 is fixed on the upper part of the cleaning tank 32 through the fixing frame of the die holder 9, the relative position between the die holder 9 and the cleaning tank 32 is adjusted, and an appropriate amount of cleaning liquid is injected into the third cavity 631;

[0058] Start the single-rod piston 42 cylinder 41. The piston rod 42 extends, pushing the mounting plate 13 downward, and then driving the brush assembly 2 downward. When the spray head 22 enters the mold base 9, the first position sensor 43 feeds back a signal, and the PLC control system starts the first water pump 7 to deliver the cleaning liquid to the central pipe 21. At this time, the cleaning liquid is sprayed from the spray head 22 onto the inner wall of the mold base 9. Meanwhile, start the motor 51 to drive the brush 24 to rotate, and cooperate with the cleaning liquid to clean the stains on the inner wall of the mold base 9;

[0059] When the spray head 22 is about to leave the lower end of the mold base 9, the second position sensor 44 feeds back a signal, and the PLC control system controls the first water pump 7 and the motor 51 to stop working. At this time, the spray head 22 no longer sprays the cleaning liquid, and the brush 24 stops rotating;

[0060] The single-rod piston 42 cylinder 41 continues to push the brush 24 downward. When the brush 24 is completely immersed in the cleaning pool 32, the third position sensor 45 feeds back a signal, and the PLC control system controls the single-rod piston 42 cylinder 41 to stop moving downward and instead pull the mounting plate 13 upward along the slide rail 12;

[0061] When the spray head 22 leaves the upper part of the cleaning pool 32 and is about to enter the mold base 9, the second position sensor 44 feeds back a signal, and the PLC control system starts the first water pump 7 and the motor 51. At this time, the brush 24 rotates, and the spray head 22 sprays the cleaning liquid;

[0062] When the spray head 22 is about to leave the upper part of the mold base 9, at this time, the first position sensor 43 feeds back a signal, and the PLC control system stops pulling the mounting plate 13 upward and instead pushes the mounting plate 13 downward.

[0063] Through the PLC control system, repeat the above actions to repeatedly clean the mold base 9 until the mold base 9 is cleaned.

[0064] Of course, during the above action process, when there is too much waste liquid in the recovery pool 31, it is necessary to control the second water pump 8 through the PLC to deliver the waste liquid to the waste liquid treatment pool 6 to ensure the supply of the cleaning liquid.

[0065] The settings and principles of the above PLC control system belong to the prior art, and are not elaborated in this application.

[0066] In the present invention, a brush assembly for cleaning the mold base is installed on the bracket. The brush assembly can enter and exit the mold base to be cleaned and rotate along its own axis under the action of the first driving assembly and the second driving assembly, and the PLC control system controls the working process of the first driving assembly and the second driving assembly, thereby realizing the cleaning work of the mold base to be cleaned; by arranging a cleaning liquid storage structure directly below the brush assembly, the brush assembly can be cleaned, and the waste liquid for cleaning the mold base can be recycled.

[0067] By setting up a waste liquid treatment pool, the waste liquid transported into the recovery pool is filtered through the first baffle, the second baffle, and the third baffle to complete the treatment of the waste liquid, and is respectively transported into the cleaning pool and the central pipe through pipelines, thereby realizing the recycling of the cleaning liquid and improving the utilization rate of the cleaning liquid.

[0068] The above is the specific implementation manner of the embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this application.
