TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning, in particular to a cylinder sleeve cleaning device and method. BACKGROUND

[0002] After machining, the cylinder sleeve needs to be cleaned of iron filings and dirt and other impurities adhering to the surface, which is usually done using an ultrasonic cleaner. Before the cylinder sleeve is cleaned by ultrasonic waves, the iron filings adhering to the cylinder sleeve need to be preliminarily cleaned to prevent too many iron filings remaining on the surface of the cylinder sleeve from being absorbed or scattered by the sound waves, thereby affecting the ultrasonic cleaning effect and cleaning quality. The impurities on the inner and outer walls of the cylinder sleeve are usually cleaned by manually spraying air flow using an air gun. In order to further improve the efficiency of the preliminary cleaning of the impurities on the surface of the cylinder sleeve, a cylinder sleeve cleaning device has been developed. The device requires an operator to vertically stand a plurality of cylinder sleeves in the cleaning device. Air flow is generated at the top of the cleaning device, and the air flow passes through the vertically standing cylinder sleeves from top to bottom to blow off the impurities on the surface of the cylinder sleeves. After a single batch of cylinder sleeves is cleaned, the cleaned cylinder sleeves in the cleaning device need to be taken out one by one. For batch cleaning of cylinder sleeves, the cleaning efficiency of the cylinder sleeves is still relatively low. In addition, for thin-walled cylinder sleeves standing in the cleaning device, the impact of the air flow from top to bottom may cause the cylinder sleeves to be blown over. After the cylinder sleeves are tipped over, the impurities on the inner walls of the cylinder sleeves are difficult to be impacted by the air flow, resulting in incomplete cleaning of the cylinder sleeves.

The machined cylinder liner is placed on the upper surface of the front end of the lower conveying belt 2 by the worker, the lower motor 24 drives the lower conveying belt 2 to drive, the upper surface of the lower conveying belt 2 drives from front to back, the lower surface of the upper conveying belt 5 drives from front to back under the drive of the upper motor 54, the cylinder liner enters between the upper conveying belt 5 and the lower conveying belt 2 under the drive of the lower conveying belt 2, because the distance between the lower surface of the upper conveying belt 5 and the lower surface of the lower conveying belt 2 is adapted to the axial length of the cylinder liner, so that after the cylinder liner enters between the lower surface of the upper conveying belt 5 and the upper surface of the lower conveying belt 2, the lower surface of the upper conveying belt 5 and the lower surface of the lower conveying belt 2 can press and clamp the cylinder liner, the cylinder liner is clamped and passes below the air jet assembly 55 from front to back, the opening of the air jet assembly 55 is vertically downward, the gas outside the air jet assembly 55 is sucked in and sprayed downward, the gas passes through the upper hole 53 of the lower surface of the upper conveying belt 5 and is sprayed on the cylinder liner, the downward flowing gas can blow away the impurities on the surface of the cylinder liner, and the impurities can pass through the lower hole 23 of the upper surface of the lower conveying belt 2 under the impact of the gas flow and enter the inside of the shielding frame 25, the shielding frame 25 can shield the gas flow and impurities inside, under the guidance of the shielding frame 25, the gas flow drives the impurities to pass through the lower hole 23 of the lower surface of the lower conveying belt 2 and enter the waste box 3, the waste box 3 can be hollow, so that the gas can be laterally discharged from the waste box 3, and the waste impurities are intercepted and collected inside the waste box 3, the worker can continuously place the cylinder liner on the upper surface of the front end of the lower conveying belt 2, the cylinder liner can continuously enter between the upper conveying belt 5 and the lower conveying belt 2 under the drive of the lower conveying belt 2, so that the cylinder liner is continuously cleaned in the clamping process, the cleaning is more stable and less likely to be dumped, the cylinder liner moves from front to back under the drive of the lower conveying belt 2 and moves away from the lower surface of the upper conveying belt 5, the cylinder liner falls into the workpiece box 4 after the lower conveying belt 2 moves to the rear end of the lower conveying belt 2 and drives the lower conveying belt 2 around the lower driven roller 22, a buffering assembly can be arranged in the workpiece box 4 for buffering the falling of the cylinder liner, and the process is repeated; the length of the lower conveying belt 2 is relatively long, so that the waste box 3 is large enough to collect the waste, and the waste box 3 is replaced from the feeding port 11 after being filled, and the workpiece box 4 is replaced from the discharging port 12 after being filled; The present application can clean the cylinder liner during clamping by driving the cylinder liner into the lower conveying belt 2 below and being sprayed by the air jet assembly 55, so that the whole cylinder liner cleaning process is more stable, and the present application can also realize continuous cleaning with higher cleaning efficiency.

[0023] Example 2: The upper hole 53 is combined by an upper inner hole 531 and an upper outer hole 532; the upper inner hole 531 is arranged close to the inner side of the upper conveying belt 5; the inner diameter of the upper inner hole 531 is larger than that of the upper outer hole 532 and they are in communication with each other; the inner block 533 is movably connected in the upper inner hole 531; the inner block 533 is connected with the upper inner hole 531 through the elastic rope 534 close to one end of the upper outer hole 532; the outer strip 535 is movably connected in the upper outer hole 532; the cross section of the outer strip 535 is cross-shaped; one end of the outer strip 535 is fixedly connected with the inner block 533 and the other end extends to the outside of the upper outer hole 532; the edge of the upper conveying belt 5 is in sealing contact with the adjusting plate 14; the air inlet of the air jet assembly 55 is in communication with the outside and the air outlet of the air jet assembly 55 is in communication with the inner side of the upper conveying belt 5.

[0024] In the embodiment, the distance between the adjacent upper holes 53 is less than the thickness of the cylinder sleeve; the plurality of upper holes 53 are evenly arranged on the surface of the upper conveying belt 5; the inner block 533 is movably connected with the upper inner hole 531; the two adjusting plates 14 are provided with the sealing groove 18 on the side close to each other; the shape of the sealing groove 18 corresponds to and is adapted to the edge of the upper conveying belt 5; and the edge of the upper conveying belt 5 is movably connected in the sealing groove 18.

[0025] When working, the worker will place the cylinder sleeve on the upper surface of the front end of the lower conveying belt 2, and then the lower conveying belt 2 will drive the cylinder sleeve to move backward into the space between the upper surface of the lower conveying belt 2 and the lower surface of the upper conveying belt 5. The upper end of the cylinder sleeve will correspond to the corresponding upper hole 53, so that the upper end of the cylinder sleeve will extrude the outer strip 535. The cross-shaped outer strip 535 will be axially movable in the upper outer hole 532 under pressure. The outer strip 535 will drive the inner block 533 to slide in the upper inner hole 531. With the pressure and movement of the outer strip 535, the inner block 533 will move out of the corresponding upper inner hole 531 and enter the inner side of the upper conveying belt 5 against the elastic force of the corresponding elastic cord 534. This makes the corresponding upper hole 53 open, and the jet assembly 55 will continuously transfer the external gas to the inner side of the upper conveying belt 5, so that the air pressure inside the upper conveying belt 5 increases. The edge of the upper conveying belt 5 is movably and sealingly connected in the sealing groove 18, so that the gas inside the upper conveying belt 5 is not easy to leak. In order to avoid the middle section of the upper conveying belt 5 from bulging, a plurality of reinforcing rods are arranged in the width direction of the upper conveying belt 5. The reinforcing rods are uniformly distributed around the driving direction of the upper conveying belt 5 to strengthen the upper conveying belt 5 and avoid the upper conveying belt 5 from bulging under the action of air pressure. If the inner block 533 is located in the upper inner hole 531, the corresponding upper hole 53 will be blocked, i.e. the upper hole 53 is closed. If the inner block 533 is located outside the upper inner hole 531, the corresponding upper hole 53 will be opened, i.e. the upper hole 53 is opened. Only the upper hole 53 extruded by the upper end of the cylinder sleeve will be opened, and the upper holes 53 at other positions will be closed. Therefore, the gas inside the upper conveying belt 5 can only be discharged along the opened upper hole 53. Since the opened upper hole 53 corresponds to the upper end of the cylinder sleeve, the airflow will impact the corresponding cylinder sleeve. Therefore, without the worker deliberately placing the cylinder sleeve, the cylinder sleeve can be more concentratedly impacted and cleaned by the gas when passing through the position directly below the jet assembly 55, further improving the cleaning strength and effect of impurities on the cylinder sleeve. In addition, during the process that the inner block 533 moves away from the upper outer hole 532, the elastic cord 534 will give the inner block 533 a pulling force, which will be transmitted to the outer strip 535 through the inner block 533. Therefore, the outer strip 535 will give the upper end of the cylinder sleeve a clamping force. Therefore, the cylinder sleeve will be further clamped after entering the space between the upper conveying belt 5 and the lower conveying belt 2, and can be clamped for the cylinder sleeve with slight axial size deviation. After the outer strip 535 on the lower surface of the upper conveying belt 5 is extruded and moved upward by the upper end of the cylinder sleeve, the outer strips 535 not extruded by the upper end of the cylinder sleeve can limit the upper end of the cylinder sleeve because they protrude out of the outer surface of the upper conveying belt 5. Therefore, the cylinder sleeve is not easy to deviate during the movement, and can move stably with the lower conveying belt 2. Finally, since the distance between adjacent upper holes 53 is less than the thickness of the cylinder sleeve (the distance is omitted and simplified in the figure for clear lines), the upper end of the cylinder sleeve can trigger more upper holes 53 to open, so that more upper holes 53 are opened to clean the cylinder sleeve.The cross section of the outer strip 535 is designed in cross shape to facilitate the smooth flow of air through the upper outer hole 532 in the upper hole 53, that is, the air enters the upper outer hole 532 along the upper inner hole 531 in the upper hole 53, and finally is discharged; as the lower conveying belt 2 is driven to move backward and move out of the upper conveying belt 5 directly below, the cylinder sleeve moves away from the corresponding outer strip 535 at the upper end, and the elastic cord 534 pulls the inner block 533 back to the upper inner hole 531, the outer strip 535 moves axially along the upper outer hole 532 and extends out of the upper conveying belt 5, so that the opened upper hole 53 is blocked again, and the closed upper hole 53 is opened by the next cylinder sleeve.

[0026] Embodiment 3 The hole diameter of the upper hole 53 and the lower hole 23 is smaller than the inner diameter of the cylinder sleeve; the plate groove 26 is arranged through the inside and outside of the lower conveying belt 2; the flap 6 is rotationally connected in the plate groove 26; the lower hole 23 is arranged through the flap 6; the edge of the flap 6 away from the rotation point is penetrated by the clamping rod 61; the clamping groove 27 is arranged on the outer wall of the lower conveying belt 2 corresponding to the position of the clamping rod 61; the shape of the flap 6 is adapted to the shape of the plate groove 26, and after the flap 6 enters the plate groove 26, the end of the clamping rod 61 is located in the clamping groove 27; the flap 6 on the upper surface of the lower conveying belt 2 is rotationally connected at the rear position of the plate groove 26.

[0027] In this embodiment, the center of gravity of the flap 6 is arranged close to the clamping rod 61; the clamping rod 61 is an iron rod; the bottom of the waste box 3 is embedded with an electromagnet 31; the clamping rod 61 is magnetically attracted by the electromagnet 31.

[0028] When working, the lower conveyor belt 2 drives the plate groove 26, the flap 6 in the plate groove 26 moves with the driving of the lower conveyor belt 2, the lower conveyor belt 2 around the lower driven roller 22 drives the plate groove 26 to move from top to bottom, the plate groove 26 drives the flap 6 to move from top to bottom, so that the plate groove 26 moves to the lower side of the lower driven roller 22, the flap 6 flips out of the corresponding plate groove 26 under the action of gravity, the bar 61 also separates from the corresponding slot 27, the flap 6 below the lower conveyor belt 2 moves forward in the state of moving out of the plate groove 26, after the flap 6 below the lower conveyor belt 2 moves to the position directly above the waste box 3, the bar 61 on the flap 6 is attracted by the electromagnet 31 and the magnetic force increases, the flap 6 moving out of the plate groove 26 is not easy to shake under the magnetic attraction of the bar 61, so that the plate groove 26 keeps a relatively stable open state, when the flap 6 below the lower conveyor belt 2 moves to the position around the lower driving roller 21, the lower conveyor belt 2 around the lower driving roller 21 drives the corresponding plate groove 26 to move from bottom to top, the plate groove 26 around the lower driving roller 21 drives the flap 6 to move from bottom to top, the flap 6 gradually flips into the plate groove 26 under the action of gravity, the end of the bar 61 at the edge of the flap 6 is clamped into the corresponding slot 27, so that the upper surface of the lower conveyor belt 2 is flush with the flap 6, the flap 6 on the upper surface of the lower conveyor belt 2 moves backward, so that when the cylinder liner is placed on the upper surface of the upper conveyor belt 5, the lower conveyor belt 2 drives the cylinder liner to enter below the upper conveyor belt 5, the air jet assembly 55 sprays air flow from top to bottom, the air flow enters between the lower surface of the upper conveyor belt 5 and the upper surface of the lower conveyor belt 2 after passing through the upper hole 53 on the lower surface of the upper conveyor belt 5, the air flow carries away the impurities on the surface of the cylinder liner and passes through the upper hole 53 on the upper surface of the lower conveyor belt 2 and enters the inside of the lower conveyor belt 2, because the plate groove 26 on the lower surface of the lower conveyor belt 2 is open, the air flow and the impurities in the inside of the lower conveyor belt 2 directly pass through the plate groove 26 and enter the waste tank, so as to avoid the impurities blown from the cylinder liner remaining in the inside of the lower conveyor belt 2, and improve the collection effect after cleaning the impurities on the cylinder liner; in addition, because of the arrangement of the electromagnet 31, the flap 6 directly above the waste box 3 keeps a vertical position, which ensures the opening effect of the plate groove 26 on the lower surface of the lower conveyor belt 2 directly above the waste box 3; the electromagnet 31 can also further attract the iron filings on the surface of the cylinder liner, so that the impurities on the surface of the cylinder liner are further cleaned, and the cylinder liner itself is more stable under the action of magnetic force.
