Description

Technical Field

[0001] The invention relates to filtering-related fields, and in particular to an intelligent screen changer for a viscous fluid filter and a use method thereof. Background Art

[0002] Screen changers are mainly used in the production of high-quality, long-process products such as chemical fiber spinning, wire drawing, pipes, blown film, cast film, laminating, plates, sheets, granulation, etc., and are especially suitable for the production of high-precision products with strict requirements on material pressure and material flow fluctuations.

[0003] Most of the existing manual screen changers require manual operation during the ring network process, which is low in safety and complex to operate.

[0004] In order to solve the above-mentioned problems, a mesh belt type fully automatic polymer material melt filter is disclosed, announcement number: CN205095519U;

[0005] However, the problem with the screen changer during use is that the positions of the existing screen box and the screen release box of the ring screen are fixed. As the screen is retracted and released, the diameter of the filter screen in the box increases / decreases accordingly, while the part of the filter screen in the screen changer is always in a parallel state, which causes the part between the screen release box and the screen box and the screen changer to gradually tilt as the screen is retracted and released, causing the filter screen to bend, and the degree of bending increases with the angle of inclination. The bending of the filter screen will greatly reduce its filtering effect and affect the screen running to a certain extent. Summary of the invention

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0050] For example, see Figures 1 to 13 , an intelligent screen changer for a viscous fluid filter, comprising a screen changer body 1 and a bottom plate 2, wherein the screen changer body 1 is fixed to the bottom plate 2 by a mounting member 201;

[0051] Two mounting plates 6 are fixed on both sides of the screen changer body 1, and a screen collection box 3 and a screen supply box 301 are respectively mounted on the two mounting plates 6. A notch 302 is provided on the opposite sides of the screen collection box 3 and the screen supply box 301. Filter fixing rods 12 are coaxially mounted in the screen collection box 3 and the screen supply box 301. A roll filter 8 is mounted on one of the filter fixing rods 12. The roll filter 8 passes through the screen changer body 1 and is fixed to the other filter fixing rod 12. Stepper assemblies are mounted on the two mounting plates 6. The two stepper assemblies are respectively connected to the two filter fixing rods 12, and the two stepper assemblies are connected via a transmission assembly.

[0052] Two receiving trays 11 coaxially rotating at the bottom ends of two filter fixing rods 12;

[0053] The two box covers 4 are detachably mounted on the net collecting box 3 and the net supply box 301 .

[0054] In the embodiment of the present invention, when the transmission assembly is working, the two filter fixing rods 12 are driven to rotate in different directions in the same direction to transport the roll filter 8, so as to achieve the effect of changing the filter without stopping the machine;

[0055] Among them, when the transmission component is working, it also drives the stepping component to work, and adjusts the positions of the net collecting box 3 and the net supply box 301 through the stepping component, so that the roll filter 8 is always in a parallel state during transportation to avoid the roll filter 8 from tilting during transportation.

[0056] Embodiment 2, which is distinguished from Embodiment 1 in that: the stepping assembly includes a No. 1 transmission rod 5, the No. 1 transmission rod 5 is coaxially fixed with the receiving tray 11, the No. 1 transmission rod 5 passes through the bottom of the net collecting box 3 or the net supply box 301, and the No. 1 transmission rod 5 also passes through a rectangular through slot 601 provided on the mounting plate 6, a limiting portion 18 is provided on the No. 1 transmission rod 5, and the No. 1 transmission rod 5 is rotatably connected with the net collecting box 3 or the net supply box 301 through the limiting portion 18;

[0057] An incomplete gear 9 is coaxially fixed on the first transmission rod 5, a rack plate 10 is fixed at the bottom of the mounting plate 6, and the incomplete gear 9 cooperates with the rack plate 10;

[0058] The two No. 1 transmission rods 5 are connected via the transmission assembly;

[0059] Two sliders 303 are fixed at the bottom of the net collecting box 3 and the net supply box 301 , and the net collecting box 3 and the net supply box 301 are slidably matched with the slide grooves 602 provided on the mounting plate 6 through the sliders 303 .

[0060] In the embodiment of the present invention, when the transmission assembly is working, the two No. 1 transmission rods 5 are driven to rotate synchronously, and when the two No. 1 transmission rods 5 rotate, the receiving tray 11 and the filter screen fixing rod 12 are driven to rotate, thereby synchronously unwinding and rewinding the roll filter screen 8. During this process, the part of the roll filter screen 8 in the screen changer body 1 is always in a tightened state, so as to avoid a series of problems caused by the roll filter screen 8 being in an untightened state when the ring screen is being performed;

[0061] When the two No. 1 transmission rods 5 rotate, the incomplete gear 9 is also driven to rotate. When the incomplete gear 9 rotates, the toothed portion of the incomplete gear 9 is engaged with the rack plate 10 to drive the incomplete gear 9 and the No. 1 transmission rod 5 to move along the length direction of the rack plate 10. When the No. 1 transmission rod 5 rotates, it drives the net collection box 3 and the net supply box 301 to move.

[0062] See also Fig.12, the net collection box 3 and the net supply box 301 move relative / oppositely during movement. When the roll filter 8 is unwound by rotating the filter fixing rod 12 on the net supply box 301, the diameter of the roll filter 8 stored in the net supply box 301 will gradually decrease as it is unwound, and the part of the roll filter 8 in the net changer body 1 is in a parallel state, which causes the roll filter 8 to tilt at the part entering the net changer body 1, thereby causing the roll filter 8 to bend, thereby affecting the phase change of the filtering structure of the roll filter 8, resulting in a significant reduction in the filtering effect, and may also cause a reduction in the passing rate of the melted material;

[0063] The present invention changes the positions of the filter fixing rod 12 and the screen collection box 3 during unwinding / rewinding, so that the unwinding and rewinding points are always parallel to the screen inlet / outlet of the screen changer body 1, thereby avoiding the above problems.

[0064] It should be noted that the bending phenomenon of the roll filter 8 can be understood as that the paper is bent after being rolled onto the roller, but there are no creases on its surface, and the roll filter 8 is the same;

[0065] Although the roll filter 8 in the present invention is made of metal material, it is more likely to bend, and as the roll filter 8 is unwound, the smaller the diameter of the stored portion of the roll filter 8 is, the more obvious the bending phenomenon is.

[0066] Embodiment 3, the distinguishing features from Embodiment 1 or / and Embodiment 2 are as follows: the transmission assembly comprises a No. 2 transmission rod 7 and a No. 3 transmission rod 701 rotatably mounted on the bottom of the base plate 2, the No. 2 transmission rod 7 and the No. 3 transmission rod 701 are connected at opposite ends via a gear set 19, and the No. 3 transmission rod 701 is connected to a driving member mounted at the bottom of the base plate 2; the gear set 19 comprises two gears meshing with each other and having a transmission ratio of 1:1, and the two gears are coaxially fixed to opposite ends of the No. 2 transmission rod 7 and the No. 3 transmission rod 701, respectively;

[0067] The second transmission rod 7 is connected to the first transmission rod 5 via a follower assembly, and the third transmission rod 701 is connected to another first transmission rod 5 via another follower assembly.

[0068] In the embodiment of the present invention, when the driving member is working, the third transmission rod 701 is driven to rotate, and when the third transmission rod 701 rotates, the second transmission rod 7 is driven to rotate relative to the third transmission rod 701 through the gear set 19, and when the second transmission rod 7 and the third transmission rod 701 rotate, the two first transmission rods 5 are driven to rotate through the follower assembly;

[0069] It should be noted that the second transmission rod 7 and the third transmission rod 701 are staggered rather than coaxially arranged.

[0070] The driving member includes a worm wheel 22 coaxially fixed to the third transmission rod 701, a worm 21 meshing with the worm wheel 22 is mounted on one side of the worm wheel 22, and the worm 21 is rotatably mounted on the bottom of the base plate 2;

[0071] The bottom of the base plate 2 is provided with a lifting platform integrally formed therewith, and a motor 20 is fixed on the lifting platform. The output shaft of the motor 20 is coaxially fixed with the worm 21 .

[0072] In the embodiment of the present invention, when the motor 20 is working, the worm 21 is driven to rotate through its output shaft, so that the worm 21 drives the worm wheel 22 to rotate, and when the worm wheel 22 rotates, the third transmission rod 701 is driven to rotate;

[0073] The worm 21 and the worm wheel 22 are relatively mature existing technologies. In the process of transmission, the worm 21 can apply self-locking to the worm wheel 22. In short, the worm wheel 22 can only be driven to rotate by the worm 21, and the worm wheel 22 cannot be used to drive the worm 21 to rotate. Since the roll filter 8 in the present invention needs to be in a tightened state during the transportation process, in order to avoid the tightening force of the roll filter 8 because the driving member does not have a locking function, the roll filter 8 is released from the tightened state during the transportation process;

[0074] It should be noted that the motor 20 in the present invention is a servo motor. Of course, in terms of the motor, there is a motor in which the worm 21 and the worm wheel 22 are integrated into the motor, also known as a worm gear motor. If this type of motor is used, the output shaft of this type of motor is connected to the third transmission rod 701 or the second transmission rod 7 through a transmission belt or a gear set, and the installation of the worm 21 and the worm wheel 22 is correspondingly cancelled.

[0075] The follower assembly includes two No. 4 transmission rods 13 rotatably mounted on the bottom of the base plate 2, and the two No. 4 transmission rods 13 are respectively located at the opposite ends of the No. 2 transmission rod 7 and the No. 3 transmission rod 701, and the No. 3 transmission rod 701 and the No. 2 transmission rod 7 are connected to the corresponding No. 4 transmission rod 13 through a bevel gear set 14; the bevel gear set 14 includes two bevel gears that are meshed with each other and have a transmission ratio of the screen changer body 1: the screen changer body 1, and the two bevel gears are coaxially fixed to the No. 4 transmission rod 13 and the No. 2 transmission rod 7 or the No. 3 transmission rod 701 respectively;

[0076] The transmission cylinder 15 is slidably sleeved on the fourth transmission rod 13, and at least three transmission bars 1301 are equidistantly arranged on the circumference of the fourth transmission rod 13. The fourth transmission rod 13 is slidably matched with a transmission groove 1501 starting from the inner wall of the transmission cylinder 15 through the transmission bars 1301; the transmission cylinder 15 can be driven to rotate synchronously when the fourth transmission rod 13 rotates through the sliding match between the transmission bar 1301 and the transmission groove 1501, and at the same time, the transmission cylinder 15 can slide axially along the fourth transmission rod 13, and the transmission between the transmission cylinder 15 and the fourth transmission rod 13 is not affected when the transmission cylinder 15 slides axially along the fourth transmission rod 13;

[0077] The transmission cylinder 15 is rotationally connected to the first transmission rod 5 via a transmission frame 16 rotationally connected thereto, and the transmission cylinder 15 and the first transmission rod 5 are connected via a helical gear set 17 .

[0078] In the embodiment of the present invention, when the second transmission rod 7 and the third transmission rod 701 rotate, the bevel gear set 14 drives the two fourth transmission rods 13 to rotate synchronously and move in the same direction. When the fourth transmission rod 13 rotates, the transmission cylinder 15 is driven to rotate synchronously. When the transmission cylinder 15 rotates, the helical gear set 17 drives the first transmission rod 5 to rotate, thereby making the two first transmission rods 5 rotate synchronously.

[0079] Among them, when the two No. 1 transmission rods 5 rotate, the incomplete gear 9 is driven to rotate, and the No. 1 transmission rod 5 is made to move horizontally through the meshing of the incomplete gear 9 and the rack plate 10. When the No. 1 transmission rod 5 moves horizontally, the transmission cylinder 15 is driven to move synchronously through the transmission frame 16, so that the transmission cylinder 15 moves axially toward the No. 4 transmission rod 13, and when the transmission cylinder 15 moves to any position, the No. 1 transmission rod 5 and the No. 4 transmission rod 13 will not be out of transmission, thereby achieving the two No. 1 transmission rods 5 while synchronously retracting and unreeling, while keeping the retracted and unreeled ends of the roll filter 8 parallel to the screen changer body 1, to avoid bending the roll filter 8 when it is retracted and unreeled.

[0080] It should also be noted that the incomplete gear 9 and the rack plate 10 in the present invention drive the horizontal movement of the No. 1 transmission rod 5 based on the diameter of the rolled filter screen 8 in the net collection box 3 and the net supply box 301, rather than the retracted length of the net collection box 3 and the net supply box 301. When the No. 1 transmission rod 5 rotates one circle, the diameter of the rolled filter screen 8 in the net collection box 3 and the net supply box 301 increases or decreases accordingly.

[0081] The diameter of the notch 302 is the maximum diameter of the roll filter 8 , and the roll filter 8 does not contact the notch 302 when the diameter is the minimum / maximum.

[0082] In the embodiment of the present invention, the slot 302 of the present invention is different from the inlet / outlet of the net collecting box 3 or the net supply box 301 in the prior art. In the prior art, a slightly larger slot is provided on the opposite side of the two for the roll filter 8 to enter and exit. In this method, the roll filter 8 will rub against the net collecting box 3 or the net supply box 301 when the material is entered and discharged;

[0083] When unwinding, the friction between the rolled filter screen 8 and the net supply box 301 will cause the rolled filter screen 8 to bend slightly. When rewinding, the friction between the rolled filter screen 8 and the net collection box 3 will cause some impurities attached to the rolled filter screen 8 that are difficult to clean to adhere to the net collection box 3, making the net collection box 3 also difficult to clean.

[0084] The teeth of the two rack plates 10 are in the same direction.

[0085] In the present invention, if the racks of the two rack plates 10 are in opposite directions, then when the two incomplete gears 9 are meshed with the two rack plates 10, the directions of movement are different;

[0086] The transmission ratio between the incomplete gear 9 and the rack plate 10 needs to be adjusted according to the thickness of the roll filter 8 in actual production, so that the distance moved by the incomplete gear 9 after meshing with the rack plate 10 is the same as the thickness of the roll filter 8. The thickness between the rack plate 10 and the incomplete gear 9 and the roll filter 8 is not specifically limited here.

[0087] It should also be noted that the diameter of the porous plate 101 in the screen changer body 1 of the present invention is smaller than the width of the roll filter 8 .

[0088] A positioning shaft is coaxially fixed to the bottom of the filter fixing rod 12 , and the positioning shaft is slidably matched with a positioning groove opened on the top of the No. 1 transmission rod 5 , and the receiving tray 11 is installed on the No. 1 transmission rod 5 .

[0089] In the embodiment of the present invention, the positioning shaft and the positioning groove are basically the same as the transmission bar 1301 and the transmission groove 1501 mechanism of the present invention, and their effects are basically the same. The effect is that the filter fixing rod 12 can be directly removed after the box cover 4 is opened, so as to facilitate the installation of a new roll filter 8 and the filter fixing rod 12 in the net supply box 301, and also facilitate the removal of the roll filter 8 and the filter fixing rod 12 in the net collection box 3;

[0090] The function of the box cover 4 is to limit the filter fixing rod 12 so that it will not be displaced when rotating;

[0091] It should be noted that the positioning shaft and the positioning groove in the present invention are not shown.

[0092] The present invention also provides a method for using an intelligent screen changer for a viscous fluid filter, using the intelligent screen changer for a viscous fluid filter, comprising the following steps:

[0093] Step 1: Install the roll filter 8 into the net supply box 301, and then manually unwind the roll filter 8 through the net changer body 1 and fix it to the net collection box 3;

[0094] Step 2: When the screen needs to be changed, the two filter fixing rods 12 are driven to rotate by the transmission assembly so that the two filter fixing rods 12 can synchronously complete unwinding and rewinding;

[0095] When unwinding and rewinding, the two No. 1 transmission rods 5 are driven by the stepping assembly to move based on the diameter of the rewinding / rewinding;

[0096] Step three, after the two filter fixing rods 12 are synchronously reeled in / unreeled for a certain length, the ring net work is completed.

[0097] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
