Description

Technical Field

[0001] This invention relates to the field of floating drum processing technology, and in particular to a foam filling rotary machine for the production of polymer floating drums. Background Technology

[0002] A float is a floating device used to mark the position of a lake surface. It is commonly used for navigational marking, water boundary demarcation, and ship navigation. Floats need to have a large buoyancy to ensure they can float continuously on the water surface. In the production of floats, the outer shell is first made. After the outer shell is completed, foam is filled into the shell. When filling the foam, the outer shell needs to be moved and rotated manually, which is relatively inconvenient. In order to better fill the outer shell with foam, a float processing device that facilitates loading and unloading is needed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a foam filling rotary machine for the production of polymer floating drums, which has the effect of facilitating loading and unloading.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A foam-filling rotary machine for producing polymer floating drums includes a frame with a rotary assembly. The rotary assembly includes two parallel, spaced-apart rotating shafts rotatably connected to the frame. Each rotating shaft has a coaxially fixed roller. A feeding plate is provided on one side of the rotary assembly, with the height of the feeding plate near the rotating shaft matching that of the roller. A pushing assembly is provided on the side of the feeding plate to push the floating drum on the feeding plate between the two rotating shafts. A liftable ejector mechanism is provided below the frame between the two rotating shafts to eject the processed floating drum from the two rotating shafts. A discharge plate is provided on the side of the rotary assembly away from the feeding plate, and the discharge plate is inclined and connected to a buffer mechanism.

[0005] By adopting the above technical solution, during operation, the floating drum shell to be filled with foam is placed on the loading plate with its opening facing the pushing component. Then, the pushing component moves to the side of the foremost floating drum shell and pushes it forward, positioning it between two rotating shafts. The rotating shafts are controlled to rotate, causing the drag wheel to rotate as well. The drag wheel, in turn, causes the floating drum shell to rotate. As the floating drum shell rotates, foam is filled inside. Once the foam filling is complete, the lifting and discharging mechanism lifts the floating drum and sends it out of the rotating shaft. Under the action of gravity, the floating drum rolls down from the unloading plate. The buffer mechanism cushions the floating drum, preventing excessive impact from damaging it. The entire device can quickly load and unload floating drums and facilitates foam filling, greatly increasing the efficiency of floating drum filling.

[0006] As a further feature of the present invention, the pushing assembly includes a lead screw located on the side of the feed plate and rotatably connected to the frame. A mounting bracket is fixedly connected to the lead screw nut. A swing arm is hinged to the mounting bracket. The swing arm faces the feed plate. A driving assembly for driving the swing arm to swing up and down is provided on the mounting bracket. Telescopic rods are fixedly connected to both sides of the swing arm facing the feed plate. Rollers are rotatably provided at the ends of the telescopic rods.

[0007] As a further feature of the present invention, the drive assembly includes a cylinder, one end of which is hinged to the mounting bracket and the other end is hinged to the rocker arm.

[0008] By adopting the above technical solution, the screw-controlled mounting frame reciprocates and can precisely stop at the side of each float drum shell. After the mounting frame stops at the side of the float drum shell, the cylinder retracts, pulling the swing arm to swing, so that the swing arm is in a near-vertical state. At this time, the mounting frame can drive the swing arm to reciprocate. When it is necessary to push the float drum shell, the mounting frame stops, and then the cylinder extends, pushing the swing arm to swing, so that the swing arm swings to a horizontal state. During the process of the swing arm rotating from vertical to horizontal, one end of the swing arm swings into the float drum shell, and the rollers of the telescopic rods at both ends of the swing arm abut against the inner wall of the float drum shell. Then, the screw is controlled to rotate, so that the mounting frame moves towards the rotating shaft, so that the swing arm drives the float drum shell to move. After the float drum shell is stuck between the two rotating shafts, the cylinder retracts, so that the swing arm drives the rollers to swing upward and thus disengage from the float drum shell. The mounting frame moves back to the side of the float drum shell that needs to be processed, waiting for the next loading.

[0009] As a further feature of the present invention, the lifting and discharging mechanism includes a discharge frame, on which a transmission shaft parallel to the rotation axis is rotatably mounted, and a conveyor belt is provided between the transmission shafts. A second cylinder is fixedly mounted on the frame, the second cylinder is vertically mounted, and the working end of the second cylinder is fixedly connected to the discharge frame.

[0010] As a further feature of the present invention, a first synchronous pulley is coaxially fixedly connected to the rotating shaft, a second synchronous pulley is rotatably mounted on the transmission shaft, a synchronous belt is provided between the first and second synchronous pulleys, a first connecting sleeve is coaxially fixedly mounted on the outer side of the first synchronous pulley, a second connecting sleeve is coaxially fixedly mounted on the outer side of the second synchronous pulley, a fixed-length rod is provided between the first and second connecting sleeves, the fixed-length rod is rotatably connected to the first and second connecting sleeves, the transmission shaft can move along a horizontal direction perpendicular to the axis, and a tensioning roller for tensioning the transmission belt is also provided on the discharge rack.

[0011] As a further feature of the present invention, a moving groove is provided on the discharge rack along the direction of horizontal movement of the drive shaft, a moving block is slidably disposed in the moving groove, the drive shaft is rotatably connected to the moving block, a spring is disposed in the moving groove, one end of the spring is fixedly connected to the inner wall of the moving groove, and the other end is fixedly connected to the moving block.

[0012] As a further feature of the present invention, the discharge rack is provided with vertical tension grooves at both ends of the tension roller, and a tension block is slidably disposed in the tension groove. The tension roller and the tension block are rotatably disposed. A second spring is disposed in the tension groove, one end of the second spring is fixedly connected to the inner wall of the tension groove, and the other end is fixedly connected to the tension block.

[0013] By adopting the above technical solution, the rotation of the transmission shaft can be controlled by the rotating shaft, so that the transmission belt and the rotating shaft can rotate together without adding a driving component. The extension and contraction of the second cylinder can drive the discharge rack to rise and fall, thereby driving the synchronous belt on the discharge rack to rise and fall. When the synchronous belt rises, it slowly lifts the floating drum. And through the movement of the synchronous belt, when the synchronous belt rises to be flush with the two support rollers, the floating drum can be transported out between the two rotating shafts, and the floating drum can then be discharged from the discharge plate. The fixed-length rod ensures that the two synchronous pulleys on the rotating shaft and the transmission shaft maintain a fixed distance, thus guaranteeing the normal operation of the synchronous belt. During the process of cylinder two pushing the discharge frame upward, the fixed-length rod pushes the moving block to move, thereby causing the transmission shaft to slide in the moving groove. In order to ensure that the conveyor belt is in a normal tensioned state, spring two pushes the tensioning block downward under the action of spring two, thereby causing the tensioning roller to descend and tensioning the conveyor belt. After the discharge of the floating drum is completed, cylinder two retracts, causing the discharge frame to descend. Under the action of the fixed-length rod and spring one, the moving block returns to its original position, and the conveyor belt is tensioned, pulling the tensioning roller upward, causing spring two to retract.

[0014] As a further feature of the present invention, the buffer mechanism includes a buffer frame, at least two sets of buffer ropes are fixed to the upper end of the feed plate, a sliding ring is fixedly connected to the other end of the buffer rope, a horizontal sliding rod is fixedly provided on the buffer frame, the sliding ring is slidably disposed on the sliding rod, and an impact energy absorption component is provided above the end of the feed plate on the buffer frame.

[0015] By adopting the above technical solution, when the float is pushed onto the feed plate, its speed gradually increases under the action of gravity, pulling the buffer rope. The upper end of the buffer rope pulls the sliding ring to slide on the sliding rod. When the float rolls to the lower end of the feed plate, the sliding ring hits the impact energy absorption component, and the buffer rope cannot move, causing the buffer rope to tighten and buffer the float, stopping the float and preventing it from becoming too fast and uncontrollable. The buffer rope can effectively buffer and control the float, stopping it stably at the end of the feed plate, making it convenient for workers to move.

[0016] As a further feature of the present invention, the impact energy absorption assembly includes a filling box fixedly connected to a buffer frame, the filling box being filled with a non-Newtonian fluid, an impact rod being horizontally slidably disposed on the side of the filling box facing the sliding ring, an impact plate being fixedly connected to the outside of the impact rod, the impact plate being slidably connected to the filling box, a spring three being sleeved on the impact rod, one end of the spring three being fixedly connected to the filling box and the other end being fixedly connected to the impact plate, a synchronizing block being fixedly connected between the two sliding rings, and an impact block being fixedly disposed on the side of the synchronizing block facing the impact plate.

[0017] By adopting the above technical solution, under the action of the float drum, the sliding ring slides quickly on the sliding rod. The sliding ring drives the synchronizing block and the impact block to move together. When the float drum moves to below the discharge plate, the impact block impacts the impact plate, and the impact plate drives the impact rod to impact the non-Newtonian fluid. At this time, due to the large impact force of the impact rod, the impact rod cannot be inserted into the non-Newtonian fluid. At this time, the buffer rope tightens, and the float drum is pulled to a stop by the buffer rope. After the float drum stops, the pressure of the impact rod on the non-Newtonian fluid is relatively stable. At this time, the impact rod slowly inserts into the non-Newtonian fluid, allowing the sliding ring to continue to move forward a distance, thereby allowing the float drum to slowly continue to move forward a little distance, making it convenient for workers to remove the float drum.

[0018] As a further feature of the present invention, a winding shaft is rotatably provided on the side of the buffer frame away from the impact energy absorption component, and each of the sliding rings is connected to a pull rope, which is wound onto the winding shaft.

[0019] By adopting the above technical solution and setting a winding shaft, after the processed float is removed, the winding shaft can be controlled to rotate, and the pulling rope will be wound up. During the winding process, the sliding ring will be pulled to slide on the sliding rod, thereby causing the sliding ring to drive the buffer rope to reset, waiting for the next feeding and buffering of the float.

[0020] The beneficial effects of this invention are: During operation, the float drum shell to be filled with foam is placed on the loading plate with its opening facing the pushing component. The pushing component then moves to the side of the foremost float drum shell and pushes it forward, positioning it between two rotating shafts. The rotating shafts rotate, causing the rollers to rotate as well. As the float drum shell rotates, foam is filled inside. Once the foam filling is complete, the lifting and unloading mechanism lifts the float drum and sends it off the rotating shaft. Under gravity, the float drum rolls down from the unloading plate. A buffer mechanism cushions the float drum, preventing damage from excessive impact. The entire device can quickly load and unload float drums and facilitates foam filling, greatly increasing the efficiency of float drum filling. Attached Figure Description

[0023] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0024] A foam filling rotary machine for producing polymer floating drums includes a frame 1, on which a rotary assembly is mounted. The rotary assembly includes two parallel and spaced rotating shafts 21 rotatably connected to the frame 1. Each rotating shaft 21 is coaxially fixed with a roller 22. A feeding plate 3 is mounted on one side of the rotary assembly. The side of the feeding plate 3 closest to the rotating shaft 21 is matched with the height of the roller 22. A pushing assembly 4 is mounted on the side of the feeding plate 3 to push the floating drum on the feeding plate 3 between the two rotating shafts 21. A liftable lifting and discharging mechanism 5 is mounted below the frame 1 between the two rotating shafts 21 to push the processed floating drum out of the two rotating shafts 21. A discharging plate 6 is mounted on the side of the rotary assembly away from the feeding plate 3. The discharging plate 6 is inclined and connected to a buffer mechanism 7.

[0025] During operation, the float drum shell to be filled with foam is placed on the loading plate 3 with its opening facing the pushing component 4. The pushing component 4 then moves to the side of the foremost float drum shell and pushes it forward, positioning it between the two rotating shafts 21. The rotating shafts 21 are controlled to rotate, causing the rollers 22 to rotate as well. The rollers 22 then rotate the float drum shell, filling it with foam as it rotates. Once the foam filling is complete, the lifting and discharging mechanism 5 lifts the float drum and sends it out through the rotating shafts 21. The float drum rolls down from the unloading plate 6 under gravity. The buffer mechanism 7 cushions the float drum, preventing excessive impact from damaging it. The entire device can quickly load and unload float drums and facilitate foam filling, greatly increasing the efficiency of float drum filling.

[0026] Furthermore, the pushing component 4 includes a lead screw 41 located on the side of the feeding plate 3 and rotatably connected to the frame 1. A mounting bracket 42 is fixedly connected to the lead screw nut of the lead screw 41. A swing arm 43 is hinged on the mounting bracket 42. The swing arm 43 faces the feeding plate 3. A driving component 1 for driving the swing arm 43 to swing up and down is provided on the mounting bracket 42. Telescopic rods 44 are fixedly connected to both sides of the end of the swing arm 43 facing the feeding plate 3. Rollers 45 are rotatably provided at the ends of the telescopic rods 44.

[0027] Furthermore, the drive assembly includes a cylinder 46, one end of which is hinged to the mounting bracket 42 and the other end of which is hinged to the rocker arm 43.

[0028] The lead screw 41 controls the reciprocating movement of the mounting bracket 42, allowing it to precisely stop at the side of each float drum shell. Once the mounting bracket 42 stops at the side of the float drum shell, the cylinder 46 retracts, pulling the swing arm 43 to swing, bringing it to a near-vertical position. At this point, the mounting bracket 42 can drive the swing arm 43 to reciprocate. When it is necessary to push the float drum shell, the mounting bracket 42 stops, and then the cylinder 46 extends, pushing the swing arm 43 to swing to a horizontal position. The swing arm 43 also rotates from vertical to horizontal. During the process, one end of the swing rod 43 swings into the float drum shell, and the rollers 45 of the telescopic rods 44 at both ends of the swing rod 43 abut against the inner wall of the float drum shell. Then, the control screw 41 rotates, causing the mounting frame 42 to move toward the rotating shaft 21, which causes the swing rod 43 to move the float drum shell. After the float drum shell is stuck between the two rotating shafts 21, the cylinder retracts, causing the swing rod 43 to swing the rollers 45 upward to disengage from the float drum shell. The mounting frame 42 then moves back to the side of the float drum shell that needs to be processed, waiting for the next feeding.

[0029] Furthermore, the lifting and unloading mechanism 5 includes an unloading frame 51, on which a transmission shaft 52 parallel to the rotating shaft 21 is rotatably mounted, and a conveyor belt 53 is arranged between the transmission shafts 52. A second cylinder 54 is fixedly mounted on the frame 1. The second cylinder 54 is vertically mounted, and its working end is fixedly connected to the unloading frame 51.

[0030] Furthermore, a first synchronous pulley 55 is coaxially fixedly connected to the rotating shaft 21, and a second synchronous pulley 56 is rotatably mounted on the transmission shaft 52. A synchronous belt 57 is provided between the first synchronous pulley 55 and the second synchronous pulley 56. A first connecting sleeve 58 is coaxially fixedly mounted on the outer side of the first synchronous pulley 55, and a second connecting sleeve 59 is coaxially fixedly mounted on the outer side of the second synchronous pulley 56. A fixed length rod 510 is provided between the first connecting sleeve 58 and the second connecting sleeve 59. The fixed length rod 510 is rotatably connected to the first connecting sleeve 58 and the second connecting sleeve 59. The transmission shaft 52 can move in a horizontal direction perpendicular to the axis. A tensioning roller 511 for tensioning the transmission belt is also provided on the discharge rack 51.

[0031] Furthermore, a moving groove 512 is provided on the discharge rack 51 along the direction of horizontal movement of the drive shaft 52. A moving block 513 is slidably arranged in the moving groove 512. The drive shaft 52 is rotatably connected to the moving block 513. A spring 514 is provided in the moving groove 512. One end of the spring 514 is fixedly connected to the inner wall of the moving groove 512, and the other end is fixedly connected to the moving block 513.

[0032] Furthermore, the discharge rack 51 is provided with vertical tension grooves 515 at both ends of the tension roller 511. Tension blocks 516 are slidably arranged in the tension grooves 515. The tension roller 511 and the tension blocks 516 are rotatably arranged. A second spring 517 is provided in the tension grooves 515. One end of the second spring 517 is fixedly connected to the inner wall of the tension groove 515, and the other end is fixedly connected to the tension block 516.

[0033] The drive shaft 52 can be rotated by rotating shaft 21, so that the drive belt and rotating shaft 21 can rotate together without adding a drive component. The extension and retraction of cylinder 2 54 can drive the discharge rack 51 to rise and fall, thereby driving the synchronous belt 57 on the discharge rack 51 to rise and fall. When the synchronous belt 57 rises, it slowly lifts the float drum. And through the movement of the synchronous belt 57, when the synchronous belt 57 rises to be flush with the two support rollers, the float drum can be transported out between the two rotating shafts 21, and the float drum can then be discharged from the discharge plate 6. The fixed-length rod 510 is set to maintain a fixed distance between the two synchronous pulleys on the rotating shaft 21 and the transmission shaft 52, thereby ensuring the normal operation of the synchronous belt 57. During the process of the cylinder 2 54 pushing the discharge frame 51 to rise, the fixed-length rod 510 will push the moving block 513 to move, thereby driving the transmission shaft 52 to slide in the moving groove 512. In order to ensure that the conveyor belt 53 is in a normal tension state, under the action of the spring 2 517, the spring 2 517 pushes the tensioning block 516 to fall, thereby driving the tensioning roller 511 to fall and tensioning the conveyor belt 53. After the discharge of the floating drum is completed, the cylinder 2 54 retracts, driving the discharge frame 51 to fall. Under the action of the fixed-length rod 510 and the spring 1 514, the moving block 513 returns to its original position. At the same time, the conveyor belt 53 is tensioned and pulls the tensioning roller 511 to move upward, causing the spring 2 517 to retract.

[0034] Furthermore, the buffer mechanism 7 includes a buffer frame 71, at least two sets of buffer ropes 72 are fixed to the upper end of the feed plate 6, and a sliding ring 73 is fixedly connected to the other end of the buffer ropes 72. A horizontal sliding rod 74 is fixedly installed on the buffer frame 71, and the sliding ring 73 is slidably installed on the sliding rod 74. An impact energy absorption component 75 is installed above the end of the feed plate 6 on the buffer frame 71.

[0035] When the float is pushed onto the feed plate 6, its speed gradually increases under the influence of gravity, pulling the buffer rope 72. The upper end of the buffer rope 72 pulls the sliding ring 73 to slide on the sliding rod 74. When the float rolls to the lower end of the feed plate 6, the sliding ring 73 hits the impact energy absorption component 75, and the buffer rope 72 cannot move, causing the buffer rope 72 to tighten and buffer the float, stopping the float and preventing it from becoming too fast and uncontrollable. The buffer rope 72 can effectively buffer and control the float, stopping it stably at the end of the feed plate 6, making it convenient for workers to move.

[0036] Furthermore, the impact energy absorption assembly 75 includes a filling box 751 fixedly connected to the buffer frame 71, the filling box 751 is filled with a non-Newtonian fluid 752, an impact rod 753 is horizontally slidably arranged on the side of the filling box 751 facing the sliding ring 73, an impact plate 754 is fixedly connected to the outside of the impact rod 753, the impact plate 754 is slidably connected to the filling box 751, a spring 755 is sleeved on the impact rod 753, one end of the spring 755 is fixedly connected to the filling box 751, and the other end is fixedly connected to the impact plate 754, a synchronizing block 756 is fixedly connected between the two sliding rings 73, and an impact block 757 is fixedly arranged on the side of the synchronizing block 756 facing the impact plate 754.

[0037] Under the action of the float drum, the sliding ring 73 slides quickly on the sliding rod 74. The sliding ring 73 drives the synchronizing block 756 and the impact block 757 to move together. When the float drum moves to below the discharge plate 6, the impact block 757 impacts the impact plate 754. The impact plate 754 drives the impact rod 753 to impact the non-Newtonian fluid 752. At this time, due to the large impact force of the impact rod 753, the impact rod 753 cannot be inserted into the non-Newtonian fluid 752. At this time, the buffer rope 72 is tightened, and the float drum is pulled to a stop by the buffer rope 72. After the float drum stops, the pressure of the impact rod 753 on the non-Newtonian fluid 752 is relatively stable. At this time, the impact rod 753 slowly inserts into the non-Newtonian fluid 752, so that the sliding ring 73 can continue to move forward a distance, thereby allowing the float drum to slowly continue to move forward a little distance, making it convenient for workers to remove the float drum.

[0038] Furthermore, a winding shaft 81 is rotatably provided on the side of the buffer frame 71 away from the impact energy absorption component 75, and each sliding ring 73 is connected to a pull rope 82, which is wound onto the winding shaft 81.

[0039] The winding shaft 81 is set up so that after the processed float is removed, the winding shaft 81 can be controlled to rotate and the pull rope 82 is wound up. During the winding process, the pull rope 82 will pull the sliding ring 73 to slide on the sliding rod 74, thereby causing the sliding ring 73 to drive the buffer rope 72 to reset, waiting for the next float to be fed and buffered.

[0040] As for the specific method of driving the take-up shaft 81 to rotate, it can be achieved by using a sprocket and a chain. One sprocket is set at a lower position, and the other sprocket is fixed to the take-up shaft 81. Rotating the lower sprocket will achieve the effect of rotating the take-up shaft 81 to rotate and rewind.

[0041] The working principle of this embodiment is as follows: During operation, the outer shell of the floating drum that needs to be filled with foam is placed on the feeding plate 3, with the opening facing the push component 4. First, cylinder 46 retracts, pulling the swing arm 43 to swing, bringing the swing arm 43 to a near-vertical position. Then, screw 41 controls the mounting frame 42 to move to the side of the foremost float drum shell. After the mounting frame 42 stops at the side of the float drum shell, cylinder 46 extends, pushing the swing arm 43 to swing, causing the swing arm 43 to swing to a horizontal position. During the process of the swing arm 43 rotating from vertical to horizontal, one end of the swing arm 43 swings into the float drum shell, and the rollers 45 of the telescopic rods 44 at both ends of the swing arm 43 abut against the inner wall of the float drum shell. Then, screw 41 is controlled to rotate, causing the mounting frame 42 to move toward the rotating shaft 21, causing the swing arm 43 to move the float drum shell. After the float drum shell is stuck between the two rotating shafts 21, cylinder 46 retracts, causing the swing arm 43 to swing the rollers 45 upward to disengage from the float drum shell. The mounting frame 42 then moves back to the side of the float drum shell that needs to be processed, waiting for the next loading. After the material is fed, the rotating shaft 21 is rotated by the motor. The rotating shaft 21 drives the towing wheel 22 to rotate together. The towing wheel 22 drives the floating drum shell to rotate together. When the floating drum shell rotates, foam is filled inside the floating drum shell to complete the foam filling of the floating drum shell. After the foam filling is completed, the lifting and discharge mechanism 5 lifts the floating drum and sends out the rotating shaft 21. Specifically, the cylinder 2 54 extends, driving the discharge rack 51 to rise. At this time, the rotating shaft 21 continues to rotate. The rotating shaft 21 drives the transmission shaft 52 to rotate through the action of the synchronous wheel and the synchronous belt 57, thereby causing the conveyor belt 53 to move. When the discharge rack 51 rises, the transmission belt continuously approaches the bottom of the floating drum and lifts the floating drum. Under the action of the conveyor belt 53, the floating drum is moved out of the rotating shaft 21 and enters the discharge plate 6. When the float is pushed onto the feed plate 6, its speed gradually increases under the influence of gravity, pulling the buffer rope 72. The upper end of the buffer rope 72 pulls the sliding ring 73 to slide on the sliding rod 74. When the float rolls to the lower end of the feed plate 6, the sliding ring 73 drives the impact block 757 to impact the impact plate 754. The impact plate 754 drives the impact rod 753 to impact the non-Newtonian fluid 752. At this time, due to the large impact force of the impact rod 753, the impact rod 753 cannot be inserted into the non-Newtonian fluid 752. At this time, the buffer rope 72 tightens, and the float... The drum is stopped by the buffer rope 72. After the floating drum stops, the pressure of the impact rod 753 on the non-Newtonian fluid 752 is relatively stable. At this time, the impact rod 753 slowly inserts into the non-Newtonian fluid 752, so that the sliding ring 73 can continue to move forward a distance, thereby allowing the floating drum to slowly move forward a little further. This makes it easier for workers to remove the floating drum and avoids damage to the floating drum due to excessive impact. The entire device can quickly load and unload the floating drum, and at the same time, it is convenient to fill the floating drum with foam, which greatly increases the efficiency of floating drum filling.
