Description

Technical Field

[0001] This invention relates to the field of cleaning technology, specifically to a cylinder liner cleaning device and method. Background Technology

[0002] After the cylinder liner is machined, it needs to be cleaned of iron filings and dirt on its surface. This is usually done using an ultrasonic cleaner. Before ultrasonic cleaning of the cylinder liner, the iron filings attached to the cylinder liner need to be preliminarily cleaned to prevent excessive iron filings on the cylinder liner surface from causing sound wave absorption or scattering, which would affect the ultrasonic cleaning effect and cleaning quality. The cleaning of impurities on the inner and outer walls of cylinder liners is generally done manually using an air gun to spray airflow. To further improve the efficiency of pre-treatment of impurities on the cylinder liner surface, a cylinder liner cleaning device has been developed. This device requires operators to place multiple cylinder liners vertically inside the cleaning device. Airflow is generated at the top of the cleaning device, and the airflow passes through the vertically placed cylinder liners from top to bottom, blowing off the impurities on the cylinder liner surface. After cleaning a single batch of cylinder liners, the cleaned cylinder liners need to be removed from the cleaning device one by one. For batch cylinder liner cleaning, this method is still relatively inefficient. In addition, for thin-walled cylinder liners placed vertically inside the cleaning device, the impact of the airflow from top to bottom may cause the cylinder liner to be blown over. After the cylinder liner is tilted, the impurities on its inner wall are difficult to be impacted by the airflow, resulting in incomplete cleaning of the cylinder liner. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention proposes a cylinder liner cleaning device and method. This invention uses a lower conveyor belt to drive the cylinder liner into the area below the lower conveyor belt and spray it with an air jet component, thereby enabling the cylinder liner to be cleaned during the clamping process. This makes the entire cylinder liner cleaning process more stable. In addition, this invention can also achieve continuous cleaning, resulting in higher cleaning efficiency.

[0006] Preferably, the adjusting groove has a shielding groove on its lower wall; a shielding plate is movably connected in the shielding groove; the upper end of the shielding plate is fixedly connected to the corresponding adjusting plate; a shielding frame is provided on the inner side of the lower conveyor belt; the shielding frame is located directly below the jet assembly; the upper and lower ends of the shielding frame are in contact with the inner wall of the lower conveyor belt.

[0007] Preferably, the upper hole is composed of an upper inner hole and an upper outer hole; the upper inner hole is located near the inner side of the upper conveyor belt; the inner diameter of the upper inner hole is larger than the inner diameter of the upper outer hole and they are interconnected; an inner block is movably and sealingly connected inside the upper inner hole; the inner block and the end of the upper inner hole near the upper outer hole are connected by an elastic rope; an outer strip is movably connected inside the upper outer hole; the cross section of the outer strip is cross-shaped; one end of the outer strip is fixedly connected to the inner block, and the other end extends to the outside of the upper outer hole; the edge of the upper conveyor belt is in sealed contact with the adjusting plate; the air inlet of the jet assembly is connected to the outside, and the air outlet of the jet assembly is connected to the inner side of the upper conveyor belt.

[0008] Preferably, the distance between adjacent upper holes is less than the thickness of the cylinder liner; multiple upper holes are evenly arranged on the surface of the upper conveyor belt; the inner block is slidably sealed to the upper inner hole; two adjusting plates are provided with sealing grooves on their adjacent sides; the shape of the sealing groove corresponds to and is adapted to the edge of the upper conveyor belt; the edge of the upper conveyor belt is movably sealed to the sealing groove.

[0009] Preferably, the diameters of both the upper and lower holes are smaller than the inner diameter of the cylinder liner; a plate groove is provided through the inner and outer sides of the lower conveyor belt; a flap is rotatably connected inside the plate groove; the lower hole is provided through the flap; a connecting rod passes through the edge of the flap away from the rotation point; a groove is provided on the outer wall of the lower conveyor belt at a position corresponding to the connecting rod; the shape of the flap is adapted to the shape of the plate groove, and after the flap enters the plate groove, the end of the connecting rod is located in the groove; the flap on the upper surface of the lower conveyor belt is rotatably connected to the rear position of the plate groove.

[0010] Preferably, the center of gravity of the flap is located close to the connecting rod; the connecting rod is an iron rod; an electromagnet is embedded in the bottom of the waste bin; and the connecting rod is attracted by the magnetism of the electromagnet.

[0011] A cylinder liner cleaning method, applicable to the aforementioned cylinder liner cleaning equipment, comprises the following steps: S1: Tightening the screw causes the adjusting plate to move within the adjusting groove, so that the distance between the lower surface of the upper conveyor belt and the upper surface of the lower conveyor belt is adapted to the axial length of the cylinder liner; S2: Start the lower motor to drive the lower drive roller to rotate. The rotation of the lower drive roller will drive the lower conveyor belt to move. Start the upper motor to drive the upper drive roller to rotate. The rotation of the upper drive roller will drive the upper conveyor belt to move. The lower surface of the upper conveyor belt and the upper surface of the lower conveyor belt move backward at the same speed. S3: The cylinder liner is placed upright on the upper surface of the front end of the lower conveyor belt. The upper surface of the lower conveyor belt drives the cylinder liner to enter between the upper and lower conveyor belts. The upper end of the cylinder liner squeezes the outer strip to open the corresponding upper hole. The jet assembly sprays air from the opened upper hole. The air flow carries away the impurities on the surface of the cylinder liner and passes through the lower hole on the upper surface of the lower conveyor belt. The air flow carries the impurities and, under the guidance of the shielding frame, passes through the plate groove on the lower surface of the lower conveyor belt and enters the waste bin. S4: As the upper surface of the lower conveyor belt moves backward, the cylinder liner is moved away from directly below the upper conveyor belt. The cylinder liner will then enter the workpiece box for storage as the lower conveyor belt moves, thus completing the cylinder liner cleaning process.

[0012] The beneficial effects of this invention are as follows: 1. This invention uses a lower conveyor belt to drive the cylinder liner into the area below the lower conveyor belt and where it is sprayed by the jet assembly. This allows the cylinder liner to be cleaned during the clamping process, making the entire cylinder liner cleaning process more stable. In addition, this invention can also achieve continuous cleaning, resulting in higher cleaning efficiency.

[0013] 2. In this invention, only the upper hole squeezed by the upper end of the cylinder liner will open, while the upper holes in other positions remain closed. This allows the gas inside the upper conveyor belt to be discharged only through the open upper hole. Since the open upper hole corresponds to the upper end of the cylinder liner, the airflow will impact the corresponding cylinder liner. Thus, without the need for workers to deliberately position the cylinder liner, the gas impact cleaning can be more concentrated as the cylinder liner passes directly under the jet assembly, further improving the cleaning force and effect of impurities on the cylinder liner.

[0014] 3. In this invention, the airflow carries away impurities from the cylinder liner surface and passes through the upper hole on the upper surface of the lower conveyor belt and enters the inner side of the lower conveyor belt. Since the plate groove on the lower surface of the lower conveyor belt is open, the airflow and impurities on the inner side of the lower conveyor belt directly pass through the plate groove and enter the waste trough. This avoids impurities blown off the cylinder liner from remaining on the inner side of the lower conveyor belt and improves the collection effect of impurities after cleaning the cylinder liner.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] like Figures 1 to 9 As shown, the present invention includes the following embodiments: Example 1: A cylinder liner cleaning device includes a housing 1; the housing 1 has a feed inlet 11 on its front side and a discharge outlet 12 on its rear side; a lower driving roller 21 and a lower driven roller 22 are rotatably connected to the inner wall of the housing 1; a lower conveyor belt 2 with a lower hole 23 is drivenly connected to the outer wall of the lower driving roller 21 and the lower driven roller 22; a waste bin 3 and a workpiece bin 4 are provided below the lower conveyor belt 2; the workpiece bin 4 is located at the rear end of the lower conveyor belt 2; the lower driving roller 21 is driven by a lower motor 24 on the outer wall of the housing 1. The upper drive roller 51 and the upper driven roller 52 are rotatably connected to the inner wall of the housing 1; the upper drive roller 51 and the upper driven roller 52 are driven to the outer wall of the upper conveyor belt 5 with an upper hole 53; the upper conveyor belt 5 is located directly above the lower conveyor belt 2 and the waste bin 3; the upper drive roller 51 is driven by the upper motor 54 on the outer wall of the housing 1; the inner wall of the upper conveyor belt 5 is provided with a jet assembly 55 with an opening facing downward; the distance between the lower surface of the upper conveyor belt 5 and the upper surface of the lower conveyor belt 2 is adapted to the axial length of the cylinder liner.

[0020] In this embodiment, the housing 1 is provided with an adjustment groove 13 extending laterally; an adjustment plate 14 is slidably connected to the adjustment groove 13; the upper driving roller 51 and the upper driven roller 52 are rotatably connected between the two adjustment plates 14; the upper motor 54 is fixedly connected to the outer wall of the adjustment plate 14; the output shaft of the upper motor 54 is connected to one end of the upper driving roller 51; one of the adjustment grooves 13 extends vertically and is rotatably connected to a screw 15; the screw 15 passes through the adjustment plate 14 and is threadedly connected to the adjustment plate 14; the distance between the outer walls of the upper conveyor belt 5 and the lower conveyor belt 2 changes with the rotation of the screw 15.

[0021] In this embodiment, a shielding groove 16 is provided on the lower wall of the adjusting groove 13; a shielding plate 17 is movably connected in the shielding groove 16; the upper end of the shielding plate 17 is fixedly connected to the corresponding adjusting plate 14; a shielding frame 25 is provided on the inner side of the lower conveyor belt 2; the shielding frame 25 is located directly below the jet assembly 55; the upper and lower ends of the shielding frame 25 are in contact with the inner wall of the lower conveyor belt 2.

[0022] During operation, the operator moves the machined cylinder liner to the vicinity of the cleaning equipment. Then, according to the axial length of the cylinder liner, the operator turns the screw 15, which passes through and is threadedly connected to the adjusting plate 14. Turning the screw 15 causes the adjusting plate 14 to move up and down within the adjusting groove 13. The adjusting plate 14 is fixedly connected to the lower baffle plate 17, so that the movement of the adjusting plate 14 causes the baffle plate 17 to move synchronously. The baffle plate 17 can block the space in the adjusting groove 13 below the adjusting plate 14. The up-and-down movement of the adjusting plate 14 causes the upper drive roller 51 and the upper driven roller 52 to move up and down. The up-and-down movement of the upper drive roller 51 and the upper driven roller 52 causes the upper conveyor belt 5 to move up and down, thus changing the distance between the upper conveyor belt 5 and the lower conveyor belt 2 until the distance between the lower surface of the upper conveyor belt 5 and the upper surface of the lower conveyor belt 2 is equal to the axial length of the cylinder liner. Then, the lower motor 24, the upper motor 54, and the jet assembly 5 are started. 5. During operation, the lower motor 24 rotates, which drives the lower active roller 21 to rotate. During the rotation of the lower active roller 21, the lower conveyor belt 2 is driven. The lower conveyor belt 2 is driven on the outer wall of the lower active roller 21 and the lower driven roller 22. During the rotation of the upper motor 54, the upper active roller 51 rotates. During the rotation of the upper active roller 51, the upper conveyor belt 5 is driven. The upper conveyor belt 5 is driven on the outer wall of the upper active roller 51 and the upper driven roller 52. The upper conveyor belt 5 and the lower conveyor belt 2 are driven at the same speed. The front end of the lower conveyor belt 2 is closer to the feed inlet 11 than the front end of the upper conveyor belt 5. The rear end of the lower conveyor belt 2 is closer to the discharge outlet 12 than the rear end of the upper conveyor belt 5. The opening of the jet assembly 55 faces downward, so that the jet assembly 55 sends the airflow from top to bottom through the upper hole 53 of the upper conveyor belt 5 into the space between the upper conveyor belt 5 and the lower conveyor belt 2. Finally, it passes through the lower hole 23 of the lower conveyor belt 2 and the inner side of the shielding frame 25 into the waste bin 3. The operator will place the machined cylinder liner upright on the upper surface of the front end of the lower conveyor belt 2. The lower motor 24 will drive the lower conveyor belt 2, and the upper surface of the lower conveyor belt 2 will move from front to back. The upper motor 54 will drive the upper conveyor belt 5, and the lower surface of the upper conveyor belt 5 will move from front to back. As the cylinder liner is driven by the lower conveyor belt 2, it will enter between the upper conveyor belt 5 and the lower conveyor belt 2. Since the distance between the lower surface of the upper conveyor belt 5 and the lower surface of the lower conveyor belt 2 is adapted to the axial length of the cylinder liner, after the cylinder liner enters between the lower surface of the upper conveyor belt 5 and the upper surface of the lower conveyor belt 2, the upper conveyor belt... The lower surface of conveyor belt 5 and the lower surface of conveyor belt 2 can clamp the cylinder liner. When the cylinder liner is clamped, it passes under the jet assembly 55 from front to back. The opening of the jet assembly 55 is vertically downward. The jet assembly 55 draws in external gas and sprays air from top to bottom. The gas passes through the upper hole 53 on the lower surface of the upper conveyor belt 5 and is sprayed onto the cylinder liner. The airflow from top to bottom can blow away and carry away impurities on the surface of the cylinder liner. The impurities will pass through the lower hole 23 on the upper surface of the lower conveyor belt 2 with the impact of the airflow and enter the inside of the shielding frame 25. The shielding frame 25 can block the airflow inside. Impurities are shielded. Guided by the shielding frame 25, the airflow carries impurities through the lower hole 23 on the lower surface of the lower conveyor belt 2 into the waste bin 3. The waste bin 3 can be hollow, allowing gas to escape from the side of the waste bin 3, while the waste impurities are intercepted and collected inside the waste bin 3. The operator continuously places cylinder liners onto the upper surface of the front end of the lower conveyor belt 2. The cylinder liners are continuously moved between the upper conveyor belt 5 and the lower conveyor belt 2 as the lower conveyor belt 2 is driven, so that the cylinder liners are continuously cleaned during the clamping process, making the cleaning more stable and less prone to tipping. The cylinder liner moves from front to back along the lower conveyor belt 2 and moves away from directly below the upper conveyor belt 5. The cylinder liner moves to the rear end of the lower conveyor belt 2 and, after being driven by the lower conveyor belt 2 around the lower driven roller 22, the cylinder liner falls into the workpiece box 4. A buffer assembly can be installed in the workpiece box 4 to buffer the falling cylinder liner. This process is repeated. The lower conveyor belt 2 is relatively long, so the waste box 3 is large enough to collect waste. The waste box 3 is replaced from the feed port 11 when it is full, and the workpiece box 4 is replaced from the discharge port 12 when it is full. The present invention uses the lower conveyor belt 2 to drive the cylinder liner into the lower part of the conveyor belt 2 and spray it with the jet component 55, so that the cylinder liner can be cleaned during the clamping process, thereby making the entire cylinder liner cleaning process more stable. In addition, the present invention can also achieve continuous cleaning, with higher cleaning efficiency.

[0023] Example 2: The upper hole 53 is composed of an upper inner hole 531 and an upper outer hole 532; the upper inner hole 531 is located near the inner side of the upper conveyor belt 5; the inner diameter of the upper inner hole 531 is larger than the inner diameter of the upper outer hole 532 and they are interconnected; an inner block 533 is movably and sealed within the upper inner hole 531; the inner block 533 and the end of the upper inner hole 531 near the upper outer hole 532 are connected by an elastic rope 534; an outer strip 535 is movably connected within the upper outer hole 532; the outer strip 535 has a cross-shaped cross section; one end of the outer strip 535 is fixedly connected to the inner block 533, and the other end extends to the outside of the upper outer hole 532; the edge of the upper conveyor belt 5 is in sealed contact with the adjusting plate 14; the air inlet of the jet assembly 55 is connected to the outside, and the air outlet of the jet assembly 55 is connected to the inner side of the upper conveyor belt 5.

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

[0025] During operation, the operator places the cylinder liner on the upper surface of the front end of the lower conveyor belt 2. The lower conveyor belt 2 then moves the cylinder liner backward, placing it between the lower surface of the upper conveyor belt 5 and the upper surface of the lower conveyor belt 2. The upper end of the cylinder liner aligns with the corresponding upper hole 53, causing the upper end of the cylinder liner to press against the outer strip 535. The cross-shaped outer strip 535, under pressure, will move axially within the upper outer hole 532. The pressure on the outer strip 535 will cause the inner block 533 to slide within the upper inner hole 531. As the outer strip 535 moves under pressure, the inner block 533 will overcome the elasticity of the corresponding elastic rope 534 and move out of the corresponding upper inner hole 531 and into the inner side of the upper conveyor belt 5. This opens the corresponding upper hole 53, allowing the jet assembly 55 to continuously pump external gas upward. The transfer of air inside the upper conveyor belt 5 increases the air pressure inside the upper conveyor belt 5. The edge of the upper conveyor belt 5 is connected to the sealing groove 18 to prevent gas leakage inside the upper conveyor belt 5. To prevent bulging in the middle section of the upper conveyor belt 5, multiple reinforcing rods are strung in the width direction of the upper conveyor belt 5. The multiple reinforcing rods are evenly distributed around the transmission direction of the upper conveyor belt 5 to strengthen the upper conveyor belt 5 and prevent it from bulging under air pressure. If the inner block 533 is located inside the upper inner hole 531, the corresponding upper hole 53 will be blocked, that is, the upper hole 53 will be closed. If the inner block 533 is located outside the upper inner hole 531, the corresponding upper hole 53 will be opened, that is, the upper hole 53 will be open. In this way, only the upper hole 53 squeezed by the upper end of the cylinder liner will be open. With the upper holes 53 open and closed in other positions, the gas inside the upper conveyor belt 5 can only be discharged through the open upper holes 53. Since the open upper holes 53 correspond to the upper end of the cylinder liner, the airflow will impact the corresponding cylinder liner. This allows for more concentrated gas impact cleaning as the cylinder liner passes directly under the jet assembly 55 without the need for manual positioning, further improving the cleaning force and effect on the cylinder liner. In addition, as the inner block 533 moves away from the upper outer hole 532, the elastic rope 534 applies a tension to the inner block 533. This tension is transmitted through the inner block 533 to the outer strip 535, causing the outer strip 535 to apply a clamping force to the upper end of the cylinder liner. This allows the cylinder liner to be further clamped after entering between the upper conveyor belt 5 and the lower conveyor belt 2, and can clamp cylinder liners with slight deviations in axial dimensions. After the outer strip 535 on the lower surface of the upper conveyor belt 5 is squeezed and moved upward by the upper end of the cylinder liner, the other outer strips 535 that are not squeezed by the upper end of the cylinder liner extend out of the outer surface of the upper conveyor belt 5, thus limiting the upper end of the cylinder liner. This makes it less likely for the cylinder liner to deviate during backward movement, allowing the cylinder liner to move backward stably with the transmission of the lower conveyor belt 2. Finally, since the distance between adjacent upper holes 53 is less than the thickness of the cylinder liner (simplified representation omitted in the figure for clarity), the upper end of the cylinder liner can trigger more upper holes 53 to open, allowing more upper holes 53 to be opened for concentrated cleaning of the cylinder liner.The cross-section of the outer strip 535 is designed to facilitate the smooth passage of airflow through the upper outer hole 532 in the upper hole 53. That is, the airflow enters the upper outer hole 532 along the upper inner hole 531 in the upper hole 53 and finally exits. As the lower conveyor belt 2 moves, the cylinder liner moves backward and out of direct contact with the upper conveyor belt 5, causing the upper end of the cylinder liner to disengage from the corresponding outer strip 535. The elastic rope 534 pulls the inner block 533 back to the upper inner hole 531, and the outer strip 535 moves axially along the upper outer hole 532 and extends outward from the upper conveyor belt 5, causing the opened upper hole 53 to be blocked again. The closed upper hole 53 will be opened by the pressure of the next cylinder liner.

[0026] Example 3: The diameters of the upper hole 53 and the lower hole 23 are both smaller than the inner diameter of the cylinder liner; the lower conveyor belt 2 is provided with a plate groove 26 running through it; a flap 6 is rotatably connected inside the plate groove 26; the lower hole 23 is provided through the flap 6; a connecting rod 61 passes through the edge of the flap 6 away from the rotation point; a groove 27 is provided on the outer wall of the lower conveyor belt 2 at the position corresponding to the connecting 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 connecting rod 61 is located in the groove 27; the flap 6 on the upper surface of the lower conveyor belt 2 is rotatably connected to the rear position of the plate groove 26.

[0027] In this embodiment, the center of gravity of the flap 6 is located close to the connecting rod 61; the connecting rod 61 is an iron rod; an electromagnet 31 is embedded in the bottom of the waste bin 3; the connecting rod 61 is attracted by the magnetism of the electromagnet 31.

[0028] During operation, the lower conveyor belt 2 drives the trough 26, and the flap 6 inside the trough 26 moves with the transmission of the lower conveyor belt 2. The lower conveyor belt 2 around the lower driven roller 22 drives the trough 26 to move from top to bottom, which in turn drives the flap 6 to move from top to bottom, causing the trough 26 to move below the lower driven roller 22. Under the influence of gravity, the flap 6 flips out of the corresponding trough 26, and the connecting rod 61 also disengages from the corresponding connecting groove 27. The flap 6 below the lower conveyor belt 2 moves forward while out of the trough 26, and moves to the waste bin 3. After moving upwards, the lever 61 on the flip plate 6 is attracted by the magnetic force of the electromagnet 31 and becomes larger. The flip plate 6, which has moved out of the slot 26, is not easy to shake under the magnetic attraction of the lever 61, so that the slot 26 remains in a relatively stable open state. When the flip plate 6 below the lower conveyor belt 2 moves forward to the vicinity of the lower drive roller 21, the lower conveyor belt 2 around the lower drive roller 21 will drive the corresponding slot 26 to move from bottom to top. The slot 26 around the lower drive roller 21 will drive the flip plate 6 to move from bottom to top. Under the action of gravity, the flip plate 6 will gradually flip and enter the slot 26. The end of the lever 61 on the edge of the flip plate 6 is engaged in the corresponding slot 27. This causes the upper surface of the lower conveyor belt 2 to be flush with the flap 6. The flap 6 of the lower conveyor belt 2 will block the plate groove 26, and the flap 6 on the upper surface of the lower conveyor belt 2 will move backward. Thus, when the cylinder liner is placed on the upper surface of the upper conveyor belt 5, the lower conveyor belt 2 will drive the cylinder liner to move below the upper conveyor belt 5. The jet assembly 55 sprays air from top to bottom. After passing through the upper hole 53 on the lower surface of the upper conveyor belt 5, the airflow enters the space between the lower surface of the upper conveyor belt 5 and the upper surface of the lower conveyor belt 2. The airflow carries away 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 inner side of the lower conveyor belt 2. Because the lower surface of the lower conveyor belt 2... The opening of the groove 26 on the surface of the cylinder liner allows the airflow and impurities inside the lower conveyor belt 2 to pass directly through the groove 26 into the waste trough. This prevents impurities blown off the cylinder liner from remaining inside the lower conveyor belt 2, improving the collection effect of impurities after cleaning the cylinder liner. In addition, due to the setting of the electromagnet 31, the flap 6 directly above the waste bin 3 remains in an upright position, ensuring the opening effect of the groove 26 on the lower surface of the lower conveyor belt 2 directly above the waste bin 3. The electromagnet 31 can also further attract iron filings on the surface of the cylinder liner, further cleaning the impurities on the surface of the cylinder liner. The cylinder liner itself is more stable under the attraction of magnetic force.

[0029] Example 4: A cylinder liner cleaning method, applicable to the aforementioned cylinder liner cleaning equipment, comprises the following steps: S1: Tightening the screw 15 causes the adjusting plate 14 to move within the adjusting groove 13, so that the distance between the lower surface of the upper conveyor belt 5 and the upper surface of the lower conveyor belt 2 is adapted to the axial length of the cylinder liner. S2: Start the lower motor 24 to drive the lower active roller 21 to rotate. The rotation of the lower active roller 21 will drive the lower conveyor belt 2 to drive. Start the upper motor 54 to drive the upper active roller 51 to rotate. The rotation of the upper active roller 51 will drive the upper conveyor belt 5 to drive. The lower surface of the upper conveyor belt 5 and the upper surface of the lower conveyor belt 2 move backward at the same speed. S3: The cylinder liner is placed upright on the upper surface of the front end of the lower conveyor belt 2. The upper surface of the lower conveyor belt 2 drives the cylinder liner to enter between the upper conveyor belt 5 and the lower conveyor belt 2. The upper end of the cylinder liner squeezes the outer strip 535 to open the corresponding upper hole 53. The jet assembly 55 sprays air from the opened upper hole 53. The air flow carries away the impurities on the surface of the cylinder liner and passes through the lower hole 23 on the upper surface of the lower conveyor belt 2. The air flow carries the impurities and, under the guidance of the shielding frame 25, passes through the plate groove 26 on the lower surface of the lower conveyor belt 2 and enters the waste bin 3. S4: As the upper surface of the lower conveyor belt 2 moves backward, the cylinder liner is moved away from directly below the upper conveyor belt 5. The cylinder liner will then enter the workpiece box 4 for storage as the lower conveyor belt 2 moves backward, thus completing the cylinder liner cleaning process.
