Description

Technical Field

[0001] The invention belongs to the technical field of cleaning, and specifically relates to cleaning with liquid, and more particularly to a screw cleaning machine and a cleaning method. Background Art

[0002] During the cleaning process, cleaning liquid is sprayed onto the screw through the nozzle, and air is ventilated into the nozzle to clean the screw after cleaning. However, the flow channels for water and air in the nozzle are different, and the two flow channels are connected together. As a result, during the process of the nozzle spraying water to clean the screw, the cleaning liquid flows from the position where the gas flow channel and the liquid flow channel are connected to the gas flow channel, causing leakage. As the equipment is used for a longer time, the sealing effect between the gas flow channel and the liquid flow channel decreases, making it more likely to leak during the screw cleaning process.

[0003] Therefore, due to the technical problem that the gas flow channel is prone to liquid leakage during the screw cleaning process, it is necessary to design a new screw cleaning machine and cleaning method.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0025] After research, it was found that the disadvantage of the prior art is that during the cleaning process, cleaning liquid is sprayed onto the screw through the nozzle, and after the cleaning, air is ventilated into the nozzle to clean the screw. However, the flow channels for water and air in the nozzle are different, and the two flow channels are connected together, resulting in that during the process of the nozzle spraying water to clean the screw, the cleaning liquid flows from the position where the gas flow channel and the liquid flow channel are connected to the gas flow channel, causing leakage, and as the equipment is used for a longer time, the sealing effect between the gas flow channel and the liquid flow channel decreases, resulting in more leakage during the screw cleaning process.

[0026] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] like Figure 1 and Figure 2 As shown, in at least one disclosed embodiment, a screw cleaning machine is provided, comprising: a rotating mechanism 1 and a cleaning mechanism 2; the rotating mechanism 1 is suitable for supporting the screw 4 and driving the screw 4 to rotate; the cleaning mechanism 2 is arranged on one side of the rotating mechanism 1, and the cleaning mechanism 2 is suitable for cleaning the screw 4; wherein the cleaning mechanism 2 comprises: a cleaning head 21 and an adjusting component; the cleaning head 21 is arranged on one side of the rotating mechanism 1; the adjusting component is arranged on the water inlet pipe 211 of the cleaning head 21; a strip hole 212 is opened on the water inlet pipe 211 to ventilate the cleaning head 21 through the strip hole 212; there may be two strip holes 212, and the adjusting component corresponds to the strip holes 212; the cleaning head 21 is suitable for spraying liquid onto the screw 4, and when the water inlet pipe 211 is opened, the sealing between the inside of the water inlet pipe 211 and the strip hole 212 is maintained by the adjusting component; it is achieved that the sealing between the strip hole 212 and the inside of the water inlet pipe 211 is maintained during the cleaning of the screw 4 by the cleaning head 21, so as to avoid leakage of the cleaning liquid.

[0028] like Figure 3 and Figure 4As shown, in an optional embodiment, the adjustment component includes: a movable sleeve 22; the movable sleeve 22 is slidably arranged in the water inlet pipe 211; a first ring body 221 and a second ring body 222 are arranged on the outer wall of the movable sleeve 22; the first ring body 221 is closer to the water spray port 215 of the cleaning head 21 than the second ring body 222; the outer wall of the first ring body 221 is in contact with the inner wall of the water inlet pipe 211; the outer wall of the second ring body 222 is in contact with the inner wall of the water inlet pipe 211; two sealing rings 223 are sleeved on the outer wall of the movable sleeve 22, and the sealing rings 223 are in contact with the inner wall of the water inlet pipe 211; the sealing rings 223 are located between the first ring body 221 and the second The strip hole 212 is located between the two sealing rings 223, and one sealing ring 223 is close to the first ring body 221, and the other sealing ring 223 is close to the second ring body 222; the position where the gas flow channel is connected to the water inlet pipe 211 can be in the strip hole 212; when the cleaning liquid is introduced into the water inlet pipe 211, the projection of the strip hole 212 is completely located between the two sealing rings 223. At this time, the sealing ring 223 is used to prevent the cleaning liquid in the water inlet pipe 211 from flowing out of the water inlet pipe 211 through the strip hole 212. At this time, the gas flowing out of the gas flow channel blows the sealing ring 223, so that the cross-section of the sealed air pipe changes from a circle to an ellipse, thereby strengthening the contact between the sealing ring 223 and the outer wall of the movable sleeve 22 and the inner wall of the water inlet pipe 211, thereby strengthening the sealing effect and preventing the cleaning liquid from flowing out of the strip hole 212.

[0029] In an optional embodiment, a toggle member 23 is connected to the outer wall of the movable sleeve 22, one end of the vertical portion of the toggle member 23 is connected to the outer wall of the movable sleeve 22, and the vertical portion extends out of the water inlet pipe 211 through the strip hole 212; one end of the horizontal portion of the toggle member 23 is connected to the vertical portion, the horizontal portion is located outside the water inlet pipe 211, and the length direction of the horizontal portion is parallel to the axial direction of the water inlet pipe 211; the length direction of the strip hole 212 is parallel to the axial direction of the water inlet pipe 211; the strip hole 212 can facilitate the toggle member 2 3, the outer wall of the vertical part of the toggle member 23 can contact the inner wall of the strip hole 212, and the strip hole 212 plays a guiding and limiting role in the movement of the toggle member 23; the horizontal part of the toggle member 23 is located outside the water inlet pipe 211, which is convenient for holding the toggle member 23 during manual operation to manually drive the toggle member 23 to move. The movement of the toggle member 23 can drive the moving sleeve 22 to move, so that the connecting position of the gas flow channel in the strip hole 212 moves to the outside of the two sealing rings 223, and the gas can be blown into the water inlet pipe 211.

[0030] In an optional embodiment, a clamping hole 213 is provided on the side wall of the water inlet pipe 211, and the clamping hole 213 corresponds to the strip hole 212. The clamping hole 213 is farther away from the water spray port 215 than the strip hole 212; a groove is provided on the outer wall of the movable sleeve 22, and a clamping ball 224 is provided in the groove, and the clamping ball 224 protrudes from the groove; a plurality of springs are provided between the clamping ball 224 and the groove; the groove is located between the first ring body 221 and the second ring body 222; the clamping ball 224 is adapted to the clamping hole 213, and the movable sleeve 22 is positioned after the clamping ball 224 extends into the clamping hole 213; when liquid (cleaning liquid) flows through the water inlet pipe 211 At this time, the card ball 224 is located in the card hole 213, and the movable sleeve 22 is positioned and limited by the cooperation between the card ball 224 and the card hole 213 to prevent the movement of the movable sleeve 22. At this time, the sealing ring 223 has a sealing effect to prevent the cleaning liquid in the water inlet pipe 211 from flowing out; a vertical plane can be set on the outer wall of the card ball 224 close to the water spray port 215. When the card ball 224 is located in the card hole 213, the plane contacts the inner wall of the card hole 213. The surface-to-surface contact can prevent the reset spring 241 from restoring the deformation and applying a thrust to the movable sleeve 22 to bring the card ball 224 out of the card hole 213, so as to ensure that the card ball 224 cooperates with the card hole 213 to prevent the movement of the movable sleeve 22.

[0031] like Figure 5As shown, in an optional embodiment, a pressing strip 231 is provided on the transverse portion of the toggle member 23, and the top of the pressing strip 231 extends out of the top surface of the transverse portion of the toggle member 23; the pressing strip 231 is slidably connected to the transverse portion, and the pressing strip 231 can move in the vertical direction; the bottom of the pressing strip 231 extends out from the bottom surface of the transverse portion of the toggle member 23; the width of the pressing strip 231 is smaller than the width of the card hole 213; the direction of movement of the pressing strip 231 is consistent with the support exerted by the spring on the card ball 224. The force directions are not parallel, so that the card ball 224 can better play a limiting role in the card hole 213. For example, if the direction of movement of the pressing strip 231 is vertical, the spring is set at a 45-degree angle, and the angle between the spring and the extension line of the pressing strip 231 is 45 degrees. After the cleaning of the screw 4 is completed, the card ball 224 is pushed out of the card hole 213 by pressing the pressing strip 231 downward, or the spherical surface of the card ball 224 contacts the bottom edge of the card hole 213, so that the movable sleeve 22 can move; the pressing strip 231 A spring may be provided between the horizontal portion of the toggle member 23 so that it can be reset after the pressing strip 231 is pressed down; a protrusion 232 may be provided on the bottom surface of the horizontal portion of the toggle member 23, and the position where the side wall of the protrusion 232 connects with the bottom surface is an inclined surface, and the pressing strip 231 vertically passes through the protrusion 232, and the toggle member 23 can be deformed, that is, the horizontal portion of the toggle member 23 can be lifted away from the water inlet pipe 211, and the size of the protrusion 232 can be adapted to the card hole 213, and when the card ball 224 enters the card hole 213, the protrusion 232 is also located In the locking hole 213, the protrusion 232 can also play a role in limiting the movable sleeve 22. At this time, the inclined surface of the protrusion 232 is completely located in the locking hole 213. When the movement of the movable sleeve 22 needs to be restored, the horizontal part of the toggle member 23 is lifted away from the water inlet pipe 211 while the pressing bar 231 presses the locking ball 224, so that the protrusion 232 moves outward, and the inclined surface of the protrusion 232 contacts the edge of the locking hole 213 again, or the protrusion 232 is directly moved out of the locking hole 213, so that the movable sleeve 22 can resume movement.

[0032] In an optional embodiment, a solenoid valve 24 is provided in the water inlet pipe 211, and the solenoid valve 24 is farther away from the water outlet 215 than the strip hole 212; a reset spring 241 is connected between the end surface of the movable sleeve 22 close to the solenoid valve 24 and the solenoid valve 24; the solenoid valve 24 can control the opening and closing of the water inlet pipe 211; and the reset spring 241 can reset the movable sleeve 22.

[0033] In an optional embodiment, a cavity 214 is opened inside the cleaning head 21, and the water inlet pipe 211 is connected to the water spray port 215 through the cavity 214; the size of the water spray port 215 is smaller than the size of the water inlet pipe 211, so that the flow rate of the cleaning liquid sprayed from the water spray port 215 is accelerated, thereby improving the cleaning effect; because the size of the water spray port 215 is smaller than the size of the water inlet pipe 211, the liquid will have a recoil effect on the movable sleeve 22 in the water inlet pipe 211 after entering the cavity 214, and at this time, the deformed sealing ring 223 can ensure the sealing effect.

[0034] In the initial state, the solenoid valve 24 is in a closed state, and the spring connected to the bottom of the card ball 224 makes the card ball 224 protrude from the groove, and the card ball 224 is in the strip hole 212. The vertical portion of the toggle member 23 contacts the end of the strip hole 212 close to the water spray port 215. At this time, the position where the gas flow channel is connected to the strip hole 212 is farther away from the water spray port 215 than the second ring body 222. At this time, if the gas flow channel is ventilated to the outside, the gas can enter the water inlet pipe 211, and the cleaning liquid remaining in the cleaning head 21 can be blown out by the gas. When the screw 4 needs to be cleaned, the toggle member 23 is manually driven to move, so that the movable sleeve 22 moves toward the solenoid valve 24, and the reset spring 241 is squeezed. During the movement of the movable sleeve 22, the spherical surface of the card ball 224 contacts the bottom edge of the strip hole 212, so that the card ball 224 is squeezed into the groove and shrinks, so that the card ball 224 can be removed from the strip hole 212, or the card ball 224 can be manually pressed so that the card ball 224 can be moved out of the strip hole 212, and the card ball 224 can be manually pressed. The horizontal portion of the toggle member 23 is lifted to move the protrusion 232 out of the strip hole 212. When the card ball 224 moves to the card hole 213, the spring is reset to make the card ball 224 enter the card hole 213. The plane on the side wall of the card ball 224 close to the water spray port 215 contacts the inner wall of the card hole 213 to prevent the moving sleeve 22 from moving. At this time, the protrusion 232 is located in the card hole 213 and the moving sleeve 22 is also prevented from moving. The bottom surface of the pressing strip 231 can be higher than the bottom surface of the protrusion 232. At this time, the gas flow channel is connected to the strip hole 212 at Between the two sealing rings 223, the solenoid valve 24 is manually controlled to open at this time, and the cleaning liquid cleans the screw 4 through the water spray port 215. The gas squeezes the sealing ring 223 to ensure the sealing effect and prevent the cleaning liquid from flowing out of the water inlet pipe 211; after cleaning the screw 4, the pressing bar 231 is manually pressed to make the card ball 224 shrink into the groove, so that the card ball 224 can remove the card hole 213, and at the same time, the horizontal part of the toggle member 23 is manually lifted so that the protrusion 232 can come out of the card hole 213, and the reset spring 241 drives the movable sleeve 22 to reset.

[0035] In an optional embodiment, the cleaning mechanism 2 also includes: a transverse moving pair 25; the cleaning head 21 is arranged on the transverse moving pair 25; the moving direction of the transverse moving pair 25 is parallel to the axial direction of the screw 4; when cleaning liquid is sprayed out of the water spray port 215, the cleaning head 21 is driven to move by the transverse moving pair 25 to completely clean the surface of the screw 4.

[0036] In an optional embodiment, the rotating mechanism 1 includes: at least one driver, and two pairs of support assemblies; the support assemblies are arranged on the base 3; the support assemblies are suitable for supporting the ends of the screw 4; the driver is arranged on the base 3; the driver is suitable for connecting the screw 4 to drive the screw 4 to rotate; the driver can be a motor, etc., and the motor is connected to one end of the screw 4 to drive the screw 4 to rotate, so as to ensure that the cleaning head 21 can completely clean the surface of the screw 4; the drivers can be connected to both ends of the screw 4, and the two drivers synchronously drive the screw 4 to rotate, so as to ensure the stability of the rotation of the screw 4.

[0037] In an optional embodiment, the support assembly includes: a pair of rollers 11; the rollers 11 are rotatably set on the base 3, the two rollers 11 are set in parallel, and the ends of the screw 4 are in contact with the surfaces of the two rollers 11, so that the screw 4 can rotate smoothly.
