In addition, it is not easy to extrude the tire according to the loading when the tire is plastic-pressed, which makes the raw materials loose during processing and causes uneven force on the raw materials during processing, thereby reducing the quality of tire molding.

[0016] The present invention provides a plastic compression molding machine for producing rubber inner tubes. It has the following beneficial effects: 1. The compression molding machine for producing rubber inner tubes is provided with a feeding seat, a support plate, and a swing plate. The feeding seat is moved horizontally on the support seat by the power of the push cylinder to prevent the raw materials from falling due to insufficient contact when the feeding seat is transporting the raw materials. Two support plates are provided on the feeding seat, so that the support plates guide the transportation of the raw materials on the feeding seat to prevent the raw materials from falling when contacting the rolling and pressing components, thereby ensuring the horizontal transportation of the raw materials, so that the compression molding position of the inner tube can be adjusted during operation, and the inner tube can be compressed and molded at different positions of the frame according to needs.

[0017] 2. The plastic compression molding machine for producing rubber inner tubes has a displacement arm on the frame driven by a screw to perform horizontal reciprocating motion, which is convenient for adjusting the position of the rolled material according to the different volumes of raw materials. The telescopic cylinder performs telescopic motion inside the protective frame, which is convenient for adjusting the position of the rolled material after the movable plate extends out of the protective frame, so that the protective frame is not easy to affect the rolled material, thereby increasing the bearing capacity of the protective frame itself, and adjusting the position of the movable plate by the telescopic movement of the telescopic cylinder.

[0018] 3. The plastic compression molding machine for producing rubber inner tubes is provided with multiple arc-shaped support plates on the rotating disk, so that the arc-shaped support plates are fixed when they contact the raw materials, which prevents the raw materials from falling when they are rolled and affecting the molding of the raw materials, and facilitates increasing the bearing capacity of the arc-shaped support plates themselves. After the equipment processing is completed, the protective frame can shield the parts driven by the telescopic cylinder, so that the moving plate and the rotating disk are not easily damaged inside the protective frame, which is convenient for the protective frame to protect them.

[0019] 4. The plastic compression molding machine for producing rubber inner tubes supports the rolling cylinder on the protective frame through the pressure plate to keep the rolling cylinder horizontal, thereby increasing the contact area of ​​the protective frame by using the pressure plate. The telescopic rod contracts under the pressure of the sliding block inside the pressure plate, so that the sliding block can be supported when the telescopic rod contracts to prevent the sliding block from being damaged due to excessive pressure. The movement of the sliding block is limited by the telescopic rod, thereby preventing the rolling of the raw materials from being affected by the excessive movement of the telescopic rod.

[0020] 5. The plastic compression molding machine for producing rubber inner tubes transmits the pressure of the contact raw material on the sliding block through the rolling cylinder, so that the contact surface can be replaced when the rolling cylinder rolls the raw material, preventing the surface of the rolling cylinder from being excessively worn and causing insufficient rolling of the raw material. The connecting plate is located between the sliding block and the rolling cylinder, so that the connecting plate supports the wiping plate, which is convenient for the wiping plate to contact the rolling cylinder, thereby avoiding the influence of impurities adhering to the surface of the rolling cylinder on the rolling of the raw material when the rolling cylinder is working, thereby ensuring the cleanliness of the surface of the rolling cylinder.

[0021] 6. The plastic compression molding machine for producing rubber inner tubes moves horizontally on the frame through the mounting plate driven by the rotating rod, which facilitates the cooperation between the mounting plate and the displacement arm to prevent the inner tube from being affected during plastic compression molding, resulting in incomplete molding of the raw materials. There are multiple fixing rods between the extrusion plate and the clamping plate, so that the fixing rods support different positions of the extrusion plate, which is convenient for increasing the bearing capacity of the extrusion plate, thereby ensuring the integrity of the raw materials when being squeezed by the extrusion plate.

[0022] 7. The compression molding machine for producing rubber inner tubes has a buffer plate inside the frame, so that the buffer plate squeezes the spring when it descends, which makes it easier for the spring to support the buffer plate, thereby ensuring the stability of the buffer plate. After the impurities collected by the buffer plate are cleaned, the movable ring is rotated on the middle solid rod under the thrust, so that the movable ring rotates to adjust the rotation angle of the extended plate, and the movable ring moves with the buffer plate on the middle solid rod, and the movable ring drives the extended plate to rotate in different directions.

[0023] 8. The compression molding machine for producing rubber inner tubes can adjust the extension distance on the movable ring through the extension plate, so that the extension plate can play a blocking effect when it extends out of the frame on the movable ring, so that the extension plate can limit the moving distance of the displacement arm, ensuring the convenience of the buffer plate to move inside the frame. The locking rod rotates on the movable ring, so that the movable ring is not easy to rotate when it is under pressure, so that the movable ring can squeeze the buffer plate by the pressure transmitted to the extension plate.

[0024] 9. The compression molding machine for producing the rubber inner tube is provided with four rebound rods on the buffer plate to facilitate the adjustment of the distance between the protective seat and the buffer plate, and the rebound rod cooperates with the protective seat to ensure the convenience of the protective seat to move at the bottom of the buffer plate. The internal plate is inside the protective seat, so that the internal plate reinforces the installation position of the protective seat to prevent the protective seat from being affected during operation. The internal plate inside the protective seat can increase its bearing capacity, so that the internal plate and the protective seat are not easily damaged when impacted.

[0025] 10. The plastic compression molding machine for producing rubber inner tubes has an auxiliary sleeve that cooperates with the inner plate on the protective seat to protect different positions of the protective seat, thereby increasing the bearing capacity of the auxiliary sleeve and preventing the surface of the auxiliary sleeve from being damaged when the auxiliary sleeve moves with the protective seat, which affects the integrity of the auxiliary sleeve. The support ring cooperates with the inner support frame to increase the contact area, so that the support ring and the inner support frame cooperate to play a supporting role, further enhancing the strength of the buffer plate, and facilitating the buffer plate to separate the collection position of the frame.

A feeding seat 7 is slidably connected to the top of the support seat 10. The feeding seat 7 is moved horizontally by the power of the pushing cylinder 9 on the support seat 10, so that the feeding seat 7 can load the raw materials when it moves, and prevent the raw materials from falling due to insufficient contact when the feeding seat 7 transports the raw materials. The feeding seat 7 is supported by the support seat 10, so that the feeding seat 7 can accurately feed the raw materials, and avoid the subsequent raw materials being subjected to insufficient pressure due to tilting during transportation. A support plate 8 is fixedly connected to the inner surface of the feeding seat 7, and two support plates 8 are set on the feeding seat 7, so that the support plate 8 guides the transportation of the raw materials on the feeding seat 7, thereby extending the range of raw material transportation and avoiding contact and rolling of the raw materials. When the component 3 is on the upper part, there is a situation of falling. The raw materials transported by the support plate 8 cooperate with the swing plate 6, so that the swing plate 6 rotates under the drive of the rotating motor. The swing plate 6 squeezes the raw materials when it rotates and contacts the raw materials, so that the swing plate 6 protects the raw materials transported by the feeding seat 7, thereby ensuring the horizontal transportation of the raw materials. The swing plate 6 and the support plate 8 are linked to maintain the force when the raw materials are transported, and then the swing plate 6 is used to squeeze the edge position of the raw materials. The support plate 8 is below the swing plate 6, so that the swing plate 6 moves along the inner wall of the feeding seat 7 when it swings, avoiding the tilt of the swing plate 6 when it rotates, which causes wrinkles in the raw material transportation process. The feeding seat 7 is rotatably connected to the swing plate 6 on one side close to the support plate 8, and the feeding seat 7 is fixedly connected to the push cylinder 9 on the side away from the frame 1.

The dropped impurities can be collected by the collecting assembly 5 inside the frame 1, so that subsequent equipment can clean the collected impurities and prevent the impurities from accumulating and scattering on the frame 1, which increases the difficulty of cleaning; The rolling assembly 3 includes a displacement arm 33, which is rotatably connected to the outer surface of the screw 2. The displacement arm 33 is driven by the screw 2 to perform horizontal reciprocating motion on the frame 1, so that the displacement arm 33 can adjust the position of the raw material winding, which is convenient for adjusting the position when rolling according to different volumes of raw materials. When the displacement arm 33 drives the protective frame 31 to move, the protective frame 31 is used for protection, so that the protective frame 31 is not easy to loosen on the displacement arm 33. The displacement arm 33 is displaced by the simultaneous movement of the two screws 2. The displacement arm 33 is not prone to tilt and jam when moving, thereby ensuring the convenience of the displacement arm 33 to move on the frame 1. The displacement arm 33 is used to adjust the position of contacting the raw material. The top of the displacement arm 33 is fixedly connected with a protective frame 31. The protective frame 31 can shield the parts driven by the telescopic cylinder 36 after the equipment processing is completed, so that the moving plate 32 and the rotating disk 34 are not prone to damage inside the protective frame 31, which is convenient for the protective frame 31 to protect them. The inner surface of the protective frame 31 is fixedly connected with a pressure plate 37; The telescopic cylinder 36 is fixedly connected to the inner surface of the protection frame 31. The telescopic cylinder 36 performs telescopic movement inside the protection frame 31, so that the telescopic cylinder 36 pushes the movable plate 32 to move. The movable plate 32 can be supported when it moves inside the protection frame 31, so that the movable plate 32 can be extended out of the protection frame 31 to adjust the position of the coiled material, so that the protection frame 31 is not easy to affect the coiled material, and the telescopic cylinder 36 cooperates with the movable plate 32 to support different positions of the protection frame 31, thereby ensuring the activity space inside the protection frame 31, so that the protection frame 31 can protect the internal components, thereby increasing the bearing capacity of the protection frame 31 itself, and the position of the movable plate 32 is adjusted by the extension and contraction of the telescopic cylinder 36, so that the telescopic cylinder 36 supports the movement of the movable plate 32, and the end of the telescopic cylinder 36 away from the protection frame 31 is fixedly connected with the movable plate 32. The movable plate 32 is rotatably connected to a rotating disk 34 on one side away from the telescopic cylinder 36. The rotating disk 34 is driven by the rotating motor to rotate, so that the rotating disk 34 rotates outside the protective frame 31 and drives the arc-shaped support plate 35 to rotate, so that the arc-shaped support plate 35 rotates to reel in the transported raw materials, and the raw materials can be processed when reeling in. The outer surface of the rotating disk 34 is fixedly connected to the arc-shaped support plate 35, and a plurality of arc-shaped support plates 35 are arranged on the rotating disk 34, so that the arc-shaped support plates 35 are fixed when they contact the raw materials, and there is a movable space between the two arc-shaped support plates 35, so that the arc-shaped support plates 35 are not easily affected when working on the rotating disk 34, and the raw materials are prevented from falling off when being rolled and affecting the forming of the raw materials. The arc-shaped support plates 35 cooperate with the rotating disk 34 to increase the bearing capacity of the arc-shaped support plates 35 themselves, and prevent the arc-shaped support plates 35 from bending when extruding the raw materials, resulting in insufficient force on the raw materials.

[0030] The top of the movable plate 32 is slidably connected to the protection frame 31 , and one end of the telescopic cylinder 36 away from the movable plate 32 penetrates the protection frame 31 and extends to the outside of the protection frame 31 .

The sliding block 375 is fixedly connected to one end of the telescopic rod 371 close to the protective frame 31, and the telescopic rod 371 is used to move the sliding block 375 inside the pressure plate 37. The telescopic rod 371 is contracted by the pressure of the sliding block 375, so that the sliding block 375 can be supported when the telescopic rod 371 is contracted to prevent the sliding block 375 from being damaged due to excessive pressure, and the telescopic rod 371 is extended as the pressure of the sliding block 375 is reduced, so that the telescopic rod 371 pushes the sliding block 375 to reset, so that the sliding block 375 moves to adjust the position of the rolling cylinder 374, ensuring that the rolling cylinder 374 contacts the raw material when moving, so that the movement of the sliding block 375 is limited by the telescopic rod 371, avoiding the rolling of the raw material affected by the excessive movement of the telescopic rod 371; The rolling cylinder 374 is rotatably connected to the outer surface of the sliding block 375. The rolling cylinder 374 is used to roll the raw material in contact. The pressure of the raw material in contact is transmitted on the sliding block 375 by the rolling cylinder 374, so that the rolling cylinder 374 rotates with the rotation of the rotating disk 34, so that the contact surface can be replaced when the rolling cylinder 374 rolls the raw material, and the surface wear of the rolling cylinder 374 is prevented from being too large, resulting in insufficient rolling of the raw material. The rolling cylinder 374 is horizontally installed on the sliding block 375, so that the rolling cylinder 374 corresponds to the raw material taken up by the rotating disk 34, ensuring that the rolling cylinder 374 is in full contact with the raw material for rolling.

The connecting plate 372 and the wiping plate 373 can cooperate to block the rolling cylinder 374, so that the rolling cylinder 374 is not prone to tilting during operation, and the wiping plate 373 is used to block the rolling cylinder 374 on the connecting plate 372, thereby increasing the bearing capacity of the rolling cylinder 374 during rotation.

[0035] The plastic pressing assembly 4 includes a mounting plate 41, which is driven by a rotating rod on the frame 1 to move horizontally, so that the rotating rod is driven by the adjusting motor to adjust the position of the mounting plate 41. As the mounting plate 41 moves, the plastic pressing molding position of the inner tube is adjusted, so that the mounting plate 41 and the displacement arm 33 cooperate with each other to prevent the inner tube from being affected during plastic pressing molding, resulting in incomplete molding of the raw material. The mounting plate 41 is slidably connected to the outer surface of the frame 1, and the inner surface of the mounting plate 41 is fixedly connected with an extrusion cylinder 44. Two extrusion cylinders 44 are arranged on the mounting plate 41, so that the two The extrusion cylinders 44 simultaneously perform telescopic movements, so that the extrusion cylinders 44 push the external plate 45 to move, thereby utilizing the movement of the extrusion cylinders 44 to adjust the clamping force during inner tube molding, thereby preventing the inner tube from being deformed due to insufficient force during inner tube molding, thereby improving the quality of inner tube molding. When the extrusion cylinders 44 push the external plate 45 to move, the external plate 45 moves along the mounting plate 41, so that the mounting plate 41 can guide the movement of the external plate 45, ensuring that the external plate 45 moves smoothly with the extrusion cylinders 44, and the end of the extrusion cylinder 44 away from the mounting plate 41 is fixedly connected with the external plate 45; The clamping plate 46 is fixedly connected to the side of the external plate 45 away from the extrusion cylinder 44. The clamping plate 46 moves with the external plate 45, so that the clamping plate 46 and the external plate 45 move together, which is convenient for the clamping plate 46 to squeeze the raw material wound on the rotating disk 34, and to facilitate the raw material to form the inner tube between the two clamping plates 46. The activity space generated between the side of the clamping plate 46 close to the external plate 45 and the mounting plate 41 is convenient for the rolling cylinder 374 to move with the protective frame 31, so as to prevent the rolling cylinder 374 from contacting the extrusion cylinder 4 when moving. 4 causes the raw materials to be not delivered in place. The side of the clamping plate 46 away from the external plate 45 is fixedly connected with a fixing rod 42, and the end of the fixing rod 42 away from the external plate 45 is fixedly connected with the extrusion plate 43. By providing a plurality of fixing rods 42 between the extrusion plate 43 and the clamping plate 46, the fixing rods 42 support different positions of the extrusion plate 43, which is convenient for increasing the bearing capacity of the extrusion plate 43. When the extrusion plate 43 contacts the raw materials, the raw materials can be protected, so that the position where the extrusion plate 43 contacts the raw materials is not easy to damage the raw materials, thereby ensuring the integrity of the raw materials when being squeezed by the extrusion plate 43.

[0036] The top of the external plate 45 is slidably connected to the mounting plate 41 , and the top of the clamping plate 46 is slidably connected to the mounting plate 41 .

[0037] The collecting assembly 5 includes a buffer plate 51, which is slidably connected to the inner surface of the frame 1. The buffer plate 51 is inside the frame 1, so that the buffer plate 51 is subjected to the pressure of impurities and is lowered. As the buffer plate 51 is lowered, the space for collecting impurities is adjusted. The bottom of the buffer plate 51 is provided with a spring, so that the spring is squeezed when the buffer plate 51 is lowered, so that the spring supports the buffer plate 51, thereby ensuring the stability of the buffer plate 51. After the impurities collected by the buffer plate 51 are cleaned, the spring stretches and pushes the buffer plate 51 to rise and reset, so that the spring and the buffer plate 51 cooperate to perform buffering when the collecting device is used, so as to prevent the impurities collected by the buffer plate 51 from splashing everywhere and increasing the difficulty of cleaning the impurities. The bottom of the buffer plate 51 is slidably connected with a protective seat 56. The middle fixed rod 52 is fixedly connected to the inner surface of the buffer plate 51, and the outer surface of the middle fixed rod 52 is rotatably connected with a movable ring 53. The movable ring 53 is rotated on the middle fixed rod 52 by the thrust received by the movable ring 53, so that the movable ring 53 rotates to adjust the rotation angle of the outer extension plate 54, and the movable ring 53 moves with the buffer plate 51 on the middle fixed rod 52, so that the middle fixed rod 52 supports the movable ring 53 on the buffer plate 51, and the movable ring 53 drives the outer extension plate 54 to rotate in different directions. The outer surface of the movable ring 53 is fixedly connected with the outer extension plate 54, and the extension plate 54 can be used to adjust the extension distance on the movable ring 53, so that the outer extension plate 54 can play a blocking effect when it extends out of the frame 1 on the movable ring 53, so that the outer extension plate 54 can block the displacement arm 33 The moving distance of the movable ring 53 is limited, and when the extended plate 54 is tilted, the extended plate 54 is pressed by the displacement arm 33 to push the buffer plate 51 down, thereby increasing the range of the buffer plate 51 to descend and ensuring the convenience of the buffer plate 51 to move inside the frame 1. The inner surface of the movable ring 53 is rotatably connected with a locking rod 55, and the locking rod 55 is rotated on the movable ring 53 so that the locking rod 55 is rotated to contact the middle fixed rod 52 to lock the movable ring 53, so that the movable ring 53 is not easy to rotate when it is under pressure, so that the pressure transmitted by the movable ring 53 to the extended plate 54 can squeeze the buffer plate 51, and the locking rod 55 is rotated on the movable ring 53 to adjust the locking force, so that the movable ring 53 is not easy to slip when it is under pressure.

[0038] The two ends of the locking rod 55 penetrate the movable ring 53 and extend to the outside of the movable ring 53 , and the top of the extending plate 54 extends to the outside of the buffer plate 51 .

[0039] The inner bottom of the inner cavity of the protective seat 56 is fixedly connected with an inner plate 563, and the inner plate 563 is inside the protective seat 56 to reinforce the installation position of the protective seat 56 to prevent the protective seat 56 from being affected when working, and the inner plate 563 is not easily affected inside the protective seat 56, so as to maintain the integrity of the inner plate 563 and prevent the inner plate 563 from being damaged when moving with the protective seat 56. The inner plate 563 can increase its bearing capacity inside the protective seat 56, so that the inner plate 563 and the protective seat 56 are not easily damaged when impacted, and the outer surface of the protective seat 56 is fixedly connected with a rebound Rod 561, four rebound rods 561 are arranged on the buffer plate 51, so that the rebound rod 561 fixes the protective seat 56, which is convenient for adjusting the distance between the protective seat 56 and the buffer plate 51. When the rebound rod 561 and the protective seat 56 contact the buffer plate 51, the bearing force of the buffer plate 51 can be increased to prevent the buffer plate 51 from breaking when collecting the device. The rebound rod 561 and the protective seat 56 cooperate with each other, so that the rebound rod 561 is extended and retracted to drive the protective seat 56 to move, ensuring that the protective seat 56 can move conveniently at the bottom of the buffer plate 51, and the top of the rebound rod 561 is fixedly connected to the buffer plate 51; The auxiliary sleeve 562 is fixedly connected to the bottom of the protective seat 56. The auxiliary sleeve 562 cooperates with the inner plate 563 on the protective seat 56 to protect different positions of the protective seat 56. The auxiliary sleeve 562 can increase the contact area of ​​the bottom of the protective seat 56, which is convenient for the subsequent support of the buffer plate 51. The auxiliary sleeve 562 is internally connected to the inner support frame 564, and the auxiliary sleeve 562 is reinforced by the inner support frame 564, thereby increasing the bearing force generated by the auxiliary sleeve 562, so that the inner support frame 564 and the auxiliary sleeve 562 cooperate to buffer the pressure received, further increasing its own bearing force, and preventing the auxiliary sleeve 562 from moving with the protective seat 56. The surface is not easily damaged during movement, which affects the integrity of the auxiliary sleeve 562. The inner surface of the auxiliary sleeve 562 is fixedly connected with an inner support frame 564. The bottom of the inner support frame 564 is fixedly connected with a supporting ring 565. The supporting ring 565 cooperates with the inner support frame 564 to increase the contact area. When the supporting ring 565 is lowered with the protective seat 56 to contact the frame 1, the supporting ring 565 can support the inner support frame 564, and then the supporting ring 565 is used to limit the descending distance of the buffer plate 51, so that the supporting ring 565 and the inner support frame 564 cooperate to play a supporting role, which further enhances the strength of the buffer plate 51 and facilitates the buffer plate 51 to separate the collection position of the frame 1.

[0040] Example 2, please refer to Figure 1-Figure 12On the basis of Example 1, the present invention provides a technical solution: a method for using a plastic compression molding machine for producing rubber inner tubes, step 1: placing the raw material on the feeding seat 7, using the push cylinder 9 to extend on the support seat 10 to push the feeding seat 7 to move in a direction close to the frame 1, so that the raw material moves from the feeding seat 7 to the support plate 8, the swing plate 6 is driven by the motor to rotate, and the swing plate 6 stops when it rotates to contact the raw material, and the raw material is transported as the raw material moves on the feeding seat 7, and the push cylinder 9 contracts to drive the feeding seat 7 to move in a direction away from the frame 1, thereby adjusting the position of the raw material transportation; Step 2: Use the telescopic cylinder 36 to extend on the protection frame 31 to push the moving plate 32 to move, so that the moving plate 32 drives the rotating disk 34 to gradually leave the protection frame 31, and as the screw 2 is driven by the driving motor on the frame 1 to rotate clockwise, the screw 2 drives the displacement arm 33 to move in the direction close to the plastic pressing component 4, and the rotating disk 34 stops when it corresponds to the feeding position of the raw material, so that the raw material moves to the contact arc support plate 35 through the feeding seat 7, and the rotating disk 34 is driven by the rotating motor to rotate, so that the arc support plate 35 rotates with the rotating disk 34 to coil the raw material; Step 3: The pressure plate 37 is used to move together with the protective frame 31, so that the arc-shaped support plate 35 is squeezed by the increased winding material to squeeze the rolling cylinder 374, and the rolling cylinder 374 moves on the pressure plate 37 through the sliding block 375. As the rolling cylinder 374 moves, the telescopic rod 371 is pressed to shrink, so that the rolling cylinder 374 rolls the material wound by the rotating disk 34, and the wiping plate 373 on the connecting plate 372 contacts the rolling cylinder 374 for cleaning. At this time, the impurities adhered to the surface of the rolling cylinder 374 fall off. When the thickness of the material on the arc-shaped support plate 35 is reduced, the telescopic rod 371 extends inside the pressure plate 37, so that the telescopic rod 371 pushes the sliding block 375 to reset, so that the sliding block 375 drives the rolling cylinder 374 to contact the material; Step 4: After the raw material plastic is completed, the screw rod 2 rotates clockwise, so that the screw rod 2 drives the displacement arm 33 to move to the bottom of the mounting plate 41, and the extrusion cylinder 44 is extended on the mounting plate 41 to push the external plate 45 to move, so that the external plate 45 drives the clamping plate 46 to approach the coil, and as the extrusion plate 43 clamps and fixes the clamping plate 46 on the fixing rod 42, the clamping plate 46 cooperates with the extrusion plate 43 to extrude the coil, so that the raw material is plastic-pressed and formed, and the screw rod 2 rotates counterclockwise, so that the screw rod 2 drives the displacement arm 33 to gradually move away from the mounting plate 41, and the displacement arm 33 returns to the initial position on the frame 1, and the extrusion cylinder 44 contracts to drive the clamping plates 46 to move away from each other, so that the clamping plates 46 and the extrusion plates 43 loosen the formed inner tube; Step 5: The rotating rod is driven by the adjusting motor to rotate clockwise inside the frame 1, so that the rotating rod drives the mounting plate 41 to move on the frame 1 in the direction close to the displacement arm 33, and the rotating rod rotates counterclockwise to drive the mounting plate 41 to move away from the displacement arm 33, so that the mounting plate 41 returns to the initial position on the frame 1. Impurities generated during the inner tube processing fall onto the buffer plate 51, so that the buffer plate 51 collects the impurities inside the frame 1. The buffer plate 51 descends as the impurities accumulate, and as the movable ring 53 rotates on the middle fixed rod 52, the movable ring 53 rotates to adjust the angle of the extension plate 54. After the movable ring 53 rotates, the locking rod 55 is rotated clockwise, so that the locking rod 55 contacts the middle fixed rod 52 to fix the movable ring 53. After the extension plate 54 rotates, the movement of the displacement arm 33 can be restricted. Step six: Use the buffer plate 51 to move inside the frame 1 to drive the rebound rod 561 to move, so that the rebound rod 561 drives the protective seat 56 to move up and down. When the protective seat 56 moves, it drives the auxiliary sleeve 562 and the inner plate 563 to move, and as the auxiliary sleeve 562 drives the supporting ring 565 to move through the inner support frame 564, the supporting ring 565 and the inner support frame 564 cooperate to limit the descending distance of the buffer plate 51. After the impurities on the buffer plate 51 are removed, the spring on the buffer plate 51 drives the buffer plate 51 to reset.
