Description

Technical Field

[0001] This invention relates to the field of silent tire processing equipment technology, and in particular to a column mechanism for spiral supply and application of silent sponge and its working method. Background Technology

[0002] Tire noise is generated by the friction between the tires and the road surface when a vehicle is traveling at high speed. The level of tire noise depends on the road and vehicle conditions; the worse the road conditions, the greater the tire noise. In addition, there is a significant difference in tire noise produced by asphalt roads and concrete roads. With the development of technology, some quiet tires have emerged. Quiet tires are tires with special sound-absorbing materials (such as sound-absorbing sponges) added inside the tire. They are designed to reduce cabin noise and improve driving comfort by absorbing the resonance caused by changes in air pressure between the tire and the rim.

[0003] The working principle of silent tires is relatively simple. When a car is moving, the internal air pressure between the tire and the rim constantly changes, generating resonance, which is the so-called cavity noise. This noise is usually between 150Hz and 250Hz, belonging to mid-frequency noise. Silent tires use a layer of sound-absorbing material attached to the inner wall of the tire. When vibrating air passes through the sound-absorbing foam inside the tire, friction is generated, thus attenuating the vibration and reducing the noise transmitted to the outside, thereby reducing the noise audible inside the car. When attaching the sound-absorbing foam to the inside of the tire, silent tires require sound-absorbing foam attachment equipment and tire positioning support equipment, as shown below.

[0004] A search revealed patent CN114474805B, which discloses a continuous, multi-segment silent sponge conveying and application device and method. The device includes a fixed base, on which a linear conveying mechanism and a rotary conveying mechanism are mounted. One end of the linear conveying mechanism is fixedly connected to the rotary conveying mechanism. In this continuous, multi-segment silent sponge conveying and application device, the sponge is located on one side of a conveyor plate. During conveying, a coaxial rotating component drives a connecting rod on one side to rotate, which in turn drives a conveyor component on that side to rotate and convey the sponge. Multiple conveyor components on one side are driven to perform curved rotary conveying. Then, guide rods located on both sides of the conveyor plate rotate, causing outer rollers to rotate synchronously. Both rollers simultaneously convey the inner sponge, preventing the sponge from jamming. After conveying, a pressure roller mechanism at the front end can apply and roll the sponge.

[0005] However, the above-mentioned device still has the following areas for optimization. For example, its structure is too complex. During the sponge winding process, it needs to be limited and managed from beginning to end, resulting in a relatively high failure rate. The sponge winding mechanism is not streamlined enough, for example, it includes a large number of rollers and pressure rollers, which leads to high production costs and subsequent maintenance costs. Therefore, there is an urgent need for a silent sponge spiral supply process, a drapery mechanism for application, and its working method to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention discloses a silent sponge spiral supply process, a column mechanism for application, and its working method. By setting up a sponge conveying mechanism, the sponge can be conveyed during operation. Depending on the thickness of the sponge, an electric actuator can be activated, which, in conjunction with a transmission plate, a third slide rail, and a third slide block, drives the second conveyor frame to move, adjusting the distance between the second and first conveyor frames, thereby adjusting the distance between the two material conveyor belts. This allows it to be applicable to the conveying of sponges of various thicknesses. The sponge can be ordinary sponge or sponge with adhesive backing, both of which are suitable for the spiral supply scheme of this invention.

[0007] By incorporating a sponge winding mechanism, the sponge can be spirally wound between the annular seat and the lower rotating column during operation. Furthermore, during the winding process, there is no need for end-to-end limit management; only one end of the sponge needs to be clamped and fixed for limit management. The structure is simple, eliminating the need for numerous rollers and pressure rollers, resulting in a relatively low failure rate, lower production costs, and lower subsequent maintenance costs.

[0008] By incorporating a limiting component, the sponge, after being in contact with the outer walls of the two annular seats during operation, can be effectively limited vertically by the two limiting plates, preventing the sponge from sliding up or down. Furthermore, depending on the width of the sponge, rotating the third adjusting screw drives the gear column to rotate. When the gear column rotates, it engages with the transmission teeth at opposite positions inside the upper and lower slide seats, causing the upper slide seat to move upward and the lower slide seat to move downward, thereby adjusting the distance between the two limiting plates. This allows the sponge to be adapted to various widths, thus solving the problems in the background technology.

[0009] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

The discharge end of the material conveyor belt is close to the baffle and the short-distance conveyor belt.

[0023] The working method of the silent sponge spiral supply and application drape mechanism includes the following steps:

[0024] S1. As described above, the L-shaped plate, the second electric cylinder, the top plate, the bottom plate, the first conveyor frame, the second conveyor frame, the electric push rod, the telescopic guide rod, the third slide rail, the third slide block, the material conveyor belt, the fourth drive assembly, and the transmission plate are assembled into a sponge conveying mechanism. During operation, the sponge cut to the required size is fed between the two material conveyor belts. The two sets of fourth drive assemblies work to drive the two material conveyor belts to rotate, and the sponge located between the two material conveyor belts is conveyed to the baffle and the short-distance conveyor belt by the squeezing friction until the sponge passes through the baffle and the short-distance conveyor belt and contacts the clamping assembly at the ring seat.

[0025] S2. As described above, the first slide rail, the first slide block, the upper rotating column, the lower rotating column, the first connecting seat, the short-distance conveying assembly, the second connecting seat, the ring seat, the clamping assembly, the first drive assembly, and the second drive assembly are assembled into a sponge winding mechanism. During operation, when the sponge is conveyed through the sponge conveying mechanism, passes through the short-distance conveying assembly, and comes into contact with the clamping assembly at the ring seat, the clamping cylinder in the clamping assembly can work, cooperating with two clamping blocks, to clamp and fix one end of the sponge. Then, the third drive assembly works, driving the ring seat and the second connecting seat to rotate at a certain angle, thereby driving the sponge to rotate at a certain angle. Then, the third drive assembly pauses, and the first drive assembly works, driving the second connecting seat, the ring seat, the upper rotating column, and the lower rotating column to rotate as a whole until they rotate at a certain angle. At the same time, the drive mechanism connected to the first slide block also works, driving the first slide block to move down, so that the lower rotating column can rotate and move down at the same time, thereby allowing the sponge to be wound in a spiral between the ring seat and the lower rotating column.

[0026] S3. As described above, the mounting plate, the first electric cylinder, the second slide rail, and the second slide block are assembled into a movable seat mechanism. During operation, the drive mechanism connected to the first slide block works, driving the first slide block to move down until the sponge is delivered into the tire. Then, the first electric cylinder can be activated, cooperating with the second slide rail, to drive the second slide block to move laterally at the top of the mounting frame for position adjustment. Then, through the operation of the second drive component, the ring seat is driven to rotate, cooperating with the operation of the upper tire delivery support rotation mechanism to perform the tire noise reduction sponge attachment work.

[0027] S4. As described above, depending on the thickness of the sponge, the electric actuator can be activated, in conjunction with the transmission plate, the third slide rail, and the third slide block, to move the second conveyor frame and adjust the distance between the second and first conveyor frames, thereby adjusting the distance between the two material conveyor belts. This allows for the conveying of sponges of various thicknesses. As described above, the third adjusting screw, upper slide block, lower slide block, limiting plate, and gear column are assembled into a limiting component. During operation, after the sponge is in contact with the outer walls of the two annular seats, the two limiting plates can effectively limit the sponge's vertical movement, preventing it from sliding up and down. Furthermore, by rotating the first adjusting screw, in conjunction with the connecting block and sliding component, one set of conveyor rollers can be moved, adjusting the distance between the two sets of conveyor rollers, and thus adjusting the distance between the two sets of short-distance conveyor belts. This allows for the conveying of sponges of various thicknesses.

[0028] Depending on the width of the sponge, rotating the second adjusting screw drives the first helical gear to rotate, which in turn drives the second helical gear to rotate, which in turn drives the double-ended lead screw to rotate. When the double-ended lead screw rotates, it can work with the first connecting seat to limit the slider, synchronously driving the two sliders to move closer to each other or synchronously driving the two sliders to move away from each other. This allows for adjustment of the distance between the two baffles, making it suitable for sponges of various widths. At the same time, rotating the third adjusting screw drives the gear column to rotate. When the gear column rotates, it works with the transmission teeth at opposite positions inside the upper and lower slide seats, driving the upper slide seat to move upward and the lower slide seat to move downward, thereby adjusting the distance between the two limiting plates, making it suitable for sponges of various widths.

[0029] The present invention has the following advantages over the prior art:

[0030] 1. This technical solution is equipped with a sponge conveying mechanism, which allows the cut sponge to be fed between two material conveyor belts during operation. The two material conveyor belts operate and transport the sponge between them to the baffle and the short conveyor belt through compression and friction. The distance between the two material conveyor belts can be adjusted according to the different thicknesses of the sponge, so that it can be used to transport sponges of various thicknesses.

[0031] 2. This technical solution incorporates a sponge winding mechanism. During operation, when the sponge is conveyed through the sponge conveying mechanism and passes through the short-distance conveying component, it comes into contact with the clamping component at the annular seat. The clamping cylinder in the clamping component works in conjunction with two clamping blocks to clamp and fix one end of the sponge. Subsequently, the sponge winding mechanism operates, allowing the sponge to be wound spirally between the annular seat and the lower rotating column. During the winding process, there is no need for end-to-end limit management; only one end of the sponge needs to be clamped and fixed. The structure is simple, eliminating the need for a large number of rollers and pressure rollers, resulting in a relatively low failure rate, lower production costs, and lower subsequent maintenance costs.

[0032] 3. This technical solution incorporates a limiting component, which effectively limits the sponge's vertical movement after it adheres to the outer walls of the two annular seats during operation. This prevents the sponge from sliding up or down. Furthermore, the distance between the two limiting plates can be adjusted according to the sponge's width, making it suitable for various sponge widths. Both ordinary sponges and adhesive-backed sponges are compatible with this spiral supply scheme. When using adhesive-backed sponges, the release paper on the surface of the sponge can be removed using a release paper removal mechanism before attaching it to the inner wall of the tire.

[0033] 4. This technical solution can rotate the second adjusting screw to drive the first helical gear to rotate, which in turn drives the second helical gear to rotate, and then drives the double-ended lead screw to rotate. When the double-ended lead screw rotates, it can cooperate with the second connecting seat to limit the slider, and synchronously drive the two sliders to move closer to each other or synchronously drive the two sliders to move away from each other. In this way, the distance between the two baffles can be adjusted in conjunction with the sliders, so that it can be used for sponges of various widths.

[0034] 5. In the process of conveying and winding the sponge, the sponge will not be subjected to excessive compression or stretching, so that the conveying and winding of the sponge is relatively smooth and gentle. Therefore, it will not have an adverse effect on the sponge and reduce its quality, such as excessive stretching of the sponge causing tearing damage or excessive compression of the sponge causing indentation damage.

The telescopic end of the second electric cylinder 502 is fixedly connected to the top of the top plate 503. The top of the bottom plate 504 is fixedly connected to the bottom of the top plate 503. Movable grooves are provided at both the top plate 503 and the bottom plate 504. The first conveyor frame 505 is fixedly installed at the bottom of the bottom plate 504. Multiple third conveyor frames 506 are fixedly connected to the bottom of the bottom plate 504. The top of the second conveyor frame 506 is fixedly connected to the rail 509 and the third slide block 510 is slidably connected to the rail 509. Material conveyor belts 511 are installed at both the first conveyor frame 505 and the second conveyor frame 506. Fourth drive components 512 are installed at both the first conveyor frame 505 and the second conveyor frame 506. The fourth drive components 512 are drively connected to the material conveyor belts 511. Multiple electric push rods 507 are provided. The electric push rods 507 are fixedly installed on the top of the base plate 504 by mounting parts and pass through the movable groove at the top plate 503. Multiple transmission plates 513 are fixedly connected to the top of the second conveyor frame 506. The top of the transmission plates 513 passes through the movable groove at the base plate 504 and the top plate 503 and is fixedly connected to the telescopic end of the electric push rods 507. The discharge end of the material conveyor belt 511 is close to the baffle 615 and the short-distance conveyor belt 6062.

[0064] In the specific implementation process, during operation, the sponge cut to the required size is fed between the two material conveyor belts 511. The two sets of fourth drive components 512 work to drive the two material conveyor belts 511 to rotate. The sponge located between the two material conveyor belts 511 is conveyed to the baffle 615 and the short conveyor belt 6062 by the squeezing friction force until the sponge passes through the baffle 615 and the short conveyor belt 6062 and contacts the clamping component 609 at the ring seat 608.

[0065] When the short-distance sponge conveying component 606 contacts the clamping component 609 at the annular seat 608, the clamping cylinder 6091 in the clamping component 609 can work in conjunction with the two clamping blocks 6092 to clamp and fix one end of the sponge. Then the third drive component 619 works, driving the annular seat 608 and the second connecting seat 607 to rotate at a certain angle, thereby driving the sponge to rotate at a certain angle. Then the third drive component 619 stops, and the first drive component 611 works, driving the second connecting seat 607, the annular seat 608, the upper rotating column 603 and the lower rotating column 604 to rotate as a whole until they rotate at a certain angle. At the same time, the drive mechanism connected to the first slide 602 also works, driving the first slide 602 to move down, so that the lower rotating column 604 can move down while rotating, thereby allowing the sponge to be spirally wound between the annular seat 608 and the lower rotating column 604.

[0066] During operation, after the sponge is attached to the outer wall of the two annular seats 608, the sponge can be effectively limited up and down by the two limiting plates 6104 to prevent the sponge from sliding up and down.

[0067] During operation, the first electric cylinder 402 can be activated, which, in conjunction with the second slide rail 403, drives the second slide block 404 to move laterally at the top of the mounting bracket 2 for position adjustment. The external drive mechanism of the first slide block 602 also works, driving the first slide block 602 to continue to move downward until the sponge is delivered into the tire. Then, through the operation of the second drive assembly 612, the ring seat 608 is driven to rotate, which, in conjunction with the operation of the tire delivery support rotation mechanism 3, performs the tire noise reduction sponge attachment work.

[0068] As described above, depending on the thickness of the sponge, the electric actuator 507 can be activated, which, in conjunction with the transmission plate 513, the third slide rail 509, and the third slide block 510, drives the second conveyor frame 506 to move, adjusting the distance between the second conveyor frame 506 and the first conveyor frame 505, thereby adjusting the distance between the two material conveyor belts 511. This allows for the conveying of sponges of various thicknesses. Furthermore, by rotating the first adjusting screw 620, in conjunction with the connecting block 621 and the sliding member 6063, one set of conveyor rollers 6061 can be moved, adjusting the distance between the two sets of conveyor rollers 6061, and subsequently adjusting the distance between the two sets of short-distance conveyor belts 6062, thus allowing for the conveying of sponges of various thicknesses.

[0069] Depending on the width of the sponge, rotating the second adjusting screw 616 will drive the first helical gear 617 to rotate, which in turn drives the second helical gear 618 to rotate, which in turn drives the double-ended lead screw 613 to rotate. When the double-ended lead screw 613 rotates, it can cooperate with the first connecting seat 605 to limit the slider 614, and synchronously drive the two sliders 614 to move closer to each other or move away from each other, thereby adjusting the distance between the two baffles 615 to make it suitable for conveying sponges of various widths. At the same time, rotating the third adjusting screw 6101 will drive the gear column 6105 to rotate. When the gear column 6105 rotates, it can cooperate with the transmission teeth 6107 at the opposite positions inside the upper slide 6102 and the lower slide 6103 to drive the upper slide 6102 to move upward and the lower slide 6103 to move downward, thereby adjusting the distance between the two limiting plates 6104 to make it suitable for sponges of various widths.

[0070] Among them, such as Figure 10 As shown, the first drive assembly 611 consists of a drive motor and multiple gears;

[0071] Among them, such as Figure 10 and Figure 11 As shown, the second drive assembly 612 consists of multiple drive motors, multiple transmission shafts, and multiple gears;

[0072] The second drive component 612 can drive the conveyor roller 6061 to rotate, thereby driving the short-distance conveyor belt 6062 to operate and convey the sponge.

[0073] Among them, such as Figure 11 As shown, the third drive component 619 consists of a drive motor and multiple gears.

[0074] The working method of the silent sponge spiral supply and application drape mechanism includes the following steps:

[0075] S1. As described above, the L-shaped plate 501, the second electric cylinder 502, the top plate 503, the bottom plate 504, the first conveyor frame 505, the second conveyor frame 506, the electric push rod 507, the telescopic guide rod 508, the third slide rail 509, the third slide seat 510, the material conveyor belt 511, the fourth drive assembly 512, and the transmission plate 513 are assembled into a sponge conveying mechanism 5. During operation, the sponge of the cut size is fed between the two material conveyor belts 511. The two sets of fourth drive assemblies 512 work to drive the two material conveyor belts 511 to rotate. The sponge located between the two material conveyor belts 511 is conveyed to the baffle 615 and the short-distance conveyor belt 6062 by the squeezing friction force until the sponge passes through the baffle 615 and the short-distance conveyor belt 6062 and contacts the clamping assembly 609 at the ring seat 608.

[0076] S2. As described above, the first slide rail 601, first slide block 602, upper rotating column 603, lower rotating column 604, first connecting seat 605, short-distance conveying assembly 606, second connecting seat 607, annular seat 608, clamping assembly 609, first drive assembly 611, and second drive assembly 612 are assembled into a sponge winding mechanism 6. During operation, when the sponge is conveyed by the sponge conveying mechanism 5 through the short-distance conveying assembly 606 and comes into contact with the clamping assembly 609 at the annular seat 608, the clamping cylinder 6091 in the clamping assembly 609 works in conjunction with the two clamping blocks 6092 to clamp and fix one end of the sponge. Subsequently, the third drive assembly 619 operates, causing the annular seat 608 and the second connecting seat 607 to rotate at a certain angle, thereby causing the sponge to rotate at a certain angle. Then, the third drive assembly 619 stops, and the first drive assembly 611 operates, causing the second connecting seat 607, the annular seat 608, the upper rotating column 603, and the lower rotating column 604 to rotate as a whole until they rotate at a certain angle. At the same time, the drive mechanism connected to the first slide 602 also operates, causing the first slide 602 to move downward, so that the lower rotating column 604 can move downward while rotating, thereby allowing the sponge to be spirally wound between the annular seat 608 and the lower rotating column 604.

[0077] S3. As described above, the mounting plate 401, the first electric cylinder 402, the second slide rail 403 and the second slide block 404 are assembled into a movable seat mechanism 4. During operation, the drive mechanism connected to the first slide block 602 works, driving the first slide block 602 to move down until the sponge is delivered into the tire. Then, the first electric cylinder 402 can be activated, and in conjunction with the second slide rail 403, the second slide block 404 is driven to move laterally at the top of the mounting frame 2 for position adjustment. Then, through the operation of the second drive assembly 612, the ring seat 608 is driven to rotate, and in conjunction with the operation of the upper tire delivery support rotation mechanism 3, the tire noise reduction sponge is attached.

[0078] S4. As described above, depending on the thickness of the sponge, the electric actuator 507 can be activated, cooperating with the transmission plate 513, the third slide rail 509, and the third slide block 510 to move the second conveyor frame 506, adjusting the distance between the second conveyor frame 506 and the first conveyor frame 505, thereby adjusting the distance between the two material conveyor belts 511, so as to be applicable to the conveying of sponges of various thicknesses; as described above, the third adjusting screw 6101, the upper slide block 6102, the lower slide block 6103, the limiting plate 6104, and the gear column 610 are... 5. The assembly is formed into a limiting component 610. During operation, after the sponge is in contact with the outer wall of the two annular seats 608, the two limiting plates 6104 can effectively limit the sponge's vertical movement, preventing the sponge from sliding up and down. Furthermore, by rotating the first adjusting screw 620, in conjunction with the connecting block 621 and the sliding member 6063, one set of conveying rollers 6061 can be moved to adjust the distance between the two sets of conveying rollers 6061, thereby adjusting the distance between the two sets of short-distance conveyor belts 6062, so as to be suitable for conveying sponges of various thicknesses.

[0079] Depending on the width of the sponge, rotating the second adjusting screw 616 drives the first helical gear 617 to rotate, which in turn drives the second helical gear 618 to rotate, which in turn drives the double-ended lead screw 613 to rotate. When the double-ended lead screw 613 rotates, it can cooperate with the first connecting seat 615 to limit the slider 614, synchronously driving the two sliders 614 to move closer to each other or synchronously driving the two sliders 614 to move away from each other. This, in conjunction with the sliders 614, adjusts the distance between the two baffles 615 so that it can be used for sponges of various widths. At the same time, rotating the third adjusting screw 6101 drives the gear column 6105 to rotate. When the gear column 6105 rotates, it can cooperate with the transmission teeth 6107 at the opposite positions inside the upper slide 6102 and the lower slide 6103, respectively driving the upper slide 6102 to move upward and the lower slide 6103 to move downward, thereby adjusting the distance between the two limiting plates 6104 so that it can be used for sponges of various widths.

As described above, the L-shaped plate (501), the second electric cylinder (502), the top plate (503), the bottom plate (504), the first conveyor frame (505), the second conveyor frame (506), the electric push rod (507), the telescopic guide rod (508), the third slide rail (509), the third slide block (510), the material conveyor belt (511), the fourth drive assembly (512), and the transmission plate (513) are assembled into a sponge conveying mechanism (5). During operation, the cut materials are conveyed to the sponge conveying mechanism (5). A sponge of a certain size is fed between two material conveyor belts (511). Two sets of fourth drive components (512) work to drive the two material conveyor belts (511) to rotate. The sponge located between the two material conveyor belts (511) is conveyed to the baffle (615) and the short conveyor belt (6062) by extrusion friction until the sponge passes through the baffle (615) and the short conveyor belt (6062) and comes into contact with the clamping component (609) at the ring seat (608). S2. As described above, the first slide rail (601), the first slide block (602), the upper rotating column (603), the lower rotating column (604), the first connecting seat (605), the short-distance conveying assembly (606), the second connecting seat (607), the ring seat (608), the clamping assembly (609), the first drive assembly (611), and the second drive assembly (612) are assembled into a sponge winding mechanism (6). During operation, when the sponge is conveyed by the sponge conveying mechanism (5) through the short-distance conveying assembly (606) and comes into contact with the clamping assembly (609) at the ring seat (608), the clamping cylinder (6091) in the clamping assembly (609) can work in conjunction with the two clamping blocks (6092) to hold one end of the sponge. After clamping and fixing, the third drive assembly (619) works, driving the annular seat (608) and the second connecting seat (607) to rotate at a certain angle, thereby driving the sponge to rotate at a certain angle. Then the third drive assembly (619) pauses, and the first drive assembly (611) works, driving the second connecting seat (607), the annular seat (608), the upper rotating column (603) and the lower rotating column (604) to rotate as a whole until they rotate at a certain angle. At the same time, the drive mechanism connected to the first slide (602) also works, driving the first slide (602) to move down, so that the lower rotating column (604) can move down while rotating, thereby allowing the sponge to be spirally wound between the annular seat (608) and the lower rotating column (604). S3. As described above, the mounting plate (401), the first electric cylinder (402), the second slide rail (403) and the second slide block (404) are assembled into a movable seat mechanism (4). When working, the drive mechanism connected to the first slide block (602) works, driving the first slide block (602) to move down until the sponge is delivered into the tire. Then the first electric cylinder (402) can be started, and in conjunction with the second slide rail (403), the second slide block (404) is driven to move laterally at the top of the mounting frame (2) for position adjustment. Then, through the work of the second drive assembly (612), the ring seat (608) is driven to rotate, and in conjunction with the work of the upper tire delivery support rotation mechanism (3), the tire noise reduction sponge is attached. S4. As described above, depending on the thickness of the sponge, the electric actuator (507) can be activated, cooperating with the transmission plate (513), the third slide rail (509), and the third slide block (510) to drive the second conveyor frame (506) to move, adjusting the distance between the second conveyor frame (506) and the first conveyor frame (505), thereby adjusting the distance between the two material conveyor belts (511) so as to be applicable to the conveying of sponges of various thicknesses; as described above, the third adjusting screw (6101), the upper slide block (6102), the lower slide block (6103), the limiting plate (6104), and the gear column ( (6105) is assembled into a limiting component (610). During operation, after the sponge is in contact with the outer wall of the two annular seats (608), the sponge can be effectively limited up and down by the two limiting plates (6104) to prevent the sponge from sliding up and down. Moreover, by rotating the first adjusting screw (620), in conjunction with the connecting block (621) and the sliding part (6063), one of the conveying rollers (6061) can be moved to adjust the distance between the two sets of conveying rollers (6061), and then the distance between the two sets of short conveyor belts (6062) can be adjusted so that it can be used for conveying sponges of various thicknesses. Depending on the width of the sponge, the second adjusting screw (616) can be rotated to drive the first helical gear (617) to rotate, which in turn drives the second helical gear (618) to rotate, which in turn drives the double-ended lead screw (613) to rotate. When the double-ended lead screw (613) rotates, it can cooperate with the first connecting seat (615) to limit the slider (614), and synchronously drive the two sliders (614) to move closer to each other, or synchronously drive the two sliders 614 to move away from each other, thereby cooperating with the sliders (614) to adjust the distance between the two baffles (615). The distance between the two limiting plates (6104) can be adjusted to accommodate sponges of various widths. At the same time, rotating the third adjusting screw (6101) drives the gear column (6105) to rotate. When the gear column (6105) rotates, it can cooperate with the transmission teeth (6107) at the opposite positions inside the upper slide (6102) and the lower slide (6103) to drive the upper slide (6102) to move upward and the lower slide (6103) to move downward, thereby adjusting the distance between the two limiting plates (6104) to accommodate sponges of various widths.
