Technical Field

[0001] The invention relates to the field of sealing detection devices, in particular to a sealing detection device for a gear box of a parallel twin-screw extruder. Background Art

[0002] The parallel twin-screw extruder is a machine used to manufacture insulating particles. The main functions of the parallel twin-screw extruder gearbox include speed reduction, torque increase, change of transmission direction and power distribution. During the twin-screw extrusion process, the gearbox transmits the torque of the motor to the two screws, ensuring that the two screws can rotate synchronously, thereby achieving efficient material transportation, melt mixing and pressurized extrusion.

[0003] During the processing of the parallel twin-screw extruder gearbox, a sealing detection device is used to perform sealing detection on the gearbox of the parallel twin-screw extruder to ensure its internal sealing.

[0004] During the sealing test of the existing parallel twin-screw extruder gearbox, loading and unloading requires manual participation in plugging and unplugging the air inlet and outlet used to connect the gearbox. When loading and unloading the gearbox, the gearbox that has completed the test needs to be removed, and then the gearbox to be tested needs to be placed. The need to stop the machine to complete the switching between unloading and loading is inconvenient, and alternating gearboxes wastes time, affecting efficiency.

[0005] In order to solve the above problems, we propose a parallel twin-screw extruder gear box sealing detection device. Summary of the invention

[0006] The invention aims to provide a parallel twin-screw extruder gear box sealing detection device, which has the advantage of no need to stop the machine for loading and unloading.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: A parallel twin-screw extruder gearbox sealing detection device, comprising a lower shell, a detection platform assembly is installed on the top of the lower shell, a driving assembly is also installed on the top of the lower shell, an auxiliary assembly is provided on one side of the driving assembly, a detection assembly is provided on the top of the auxiliary assembly, and a pushing assembly is installed inside the lower shell; The bottom of the lower shell is provided with a linkage component 1; A linkage component 2 is installed inside the driving component.

[0008] By adopting the above technical scheme, two twin-screw extruder gearboxes can be placed at the same time by setting up a detection table component and a pushing component; when one gearbox is being tested, the other gearbox can wait for testing. When one gearbox completes the test, the other gearbox can be moved to the testing position and actively connected for sealing testing with the cooperation of the driving component, the auxiliary component and the detection component. At this time, the gearbox that has completed the test can be unloaded and a new gearbox to be tested can be replaced; the two gearboxes can be used alternately, and the detection component can continuously detect the gearbox without stopping the machine; by setting up the driving component, the detection table component and the detection component, the air inlet and the air outlet of the gearbox can be automatically docked and sealed, so as to facilitate rapid testing; by arranging the manual operation structure linkage component one and linkage component two inside the pushing component and the driving component, manual operation can be performed when the cylinder of the pushing component fails and the drive motor of the driving component fails, so as to avoid the cylinder or drive motor failure affecting the detection work of the gearbox.

[0009] The present invention is further configured as follows: the detection platform assembly includes a detection platform, the top of the detection platform is fixedly connected to a side baffle, one side of the side baffle is fixedly connected to two groups of limit blocks, and the number of limit blocks in each group is two.

[0010] The above technical solution is adopted, and the detection platform assembly is set up to place the gear box; wherein the two limit blocks of each group of two limit blocks are used to limit the gear box, and when the gear box is placed, one side of the gear box is pushed between the two limit blocks, and the displacement of the detection platform is waited; By using two limit blocks to limit the gear box, it can be ensured that when the gear box reaches the detection position, the air inlet and the air outlet of the gear box correspond to the two sealing sleeves.

[0011] The present invention is further configured as follows: the driving assembly comprises a connecting shell, the bottom of the connecting shell is fixedly connected to the lower shell, a driving motor is fixedly installed on one side of the connecting shell, a threaded sleeve is fixedly installed on the output end of the driving motor through a coupling, and a threaded rod is connected to the internal thread of the threaded sleeve; The threaded sleeve is rotatably connected to the connecting shell via a bearing.

[0012] The above technical solution is adopted to drive the clamping plate to approach and move away from the gear box through the setting of the driving assembly; The principle is that the drive motor starts, and its output end rotates, the output end of the drive motor drives the threaded sleeve to rotate, and the threaded sleeve rotates to drive the threaded rod inside it to extend or retract; the extension and retraction of the threaded rod are specifically determined by the rotation direction of the threaded sleeve; the start time of the drive motor is controlled by the controller, and the controller controls the output end of the motor to rotate in different reverse directions, start and shut down at different times, which is the existing technology and will not be elaborated here; When the threaded rod is extended, the threaded rod pushes the clamping plate to contact the mounting plate of the gear box, and cooperates with the side baffle to clamp the gear box to achieve the positioning of the gear box; when the threaded rod is retracted, the clamping plate is pulled away from the gearbox.

[0013] The present invention is further configured as follows: the auxiliary component includes a clamping plate, the side of the clamping plate close to the threaded rod is fixedly connected to the threaded rod, the side of the clamping plate close to the threaded rod is also fixedly connected to two guide rods, the top of the lower shell is fixedly connected to two guide plates, and the interiors of the two guide plates are respectively slidably connected to the two guide rods.

[0014] The above technical solution is adopted, through the setting of the auxiliary component, it is used to cooperate with the side baffle to clamp the gear box, and it is also used to assist the driving component to perform telescopic work; The clamping plate is used to contact the mounting plate of the gear box and cooperate with the side baffle to form a clamp; The guide rod and the guide plate are used to guide the clamping plate and limit the clamping plate to only linear movement.

[0015] The present invention is further configured as follows: the detection component includes a support frame, the support frame is fixedly connected to the clamping plate, a touch screen and an air pump are respectively installed on the top of the support frame, an air outlet of the air pump is connected to a hose, two fixing frames are installed on one side of the support frame, and one end of the two fixing frames is respectively fixedly connected to a flow sensor 1 and a flow sensor 2; One end of the hose is connected to a flow sensor; One side of the flow sensor 1 and the flow sensor 2 are both connected with a sealing sleeve, the sealing sleeve is made of silicone, and the surface of the sealing sleeve is processed with folding marks.

[0016] The above technical solution is used to detect the sealing performance of the gear box of the parallel twin-screw extruder by setting the detection component; Among them, the support frame is used to support the air pump, touch screen, and fixing frame; The two fixing frames are used to support flow sensor 1 and flow sensor 2 respectively; The air inlet and air outlet of the parallel twin-screw extruder gearbox are of the same size, and the inner diameter of the sealing sleeve is larger than the air inlet and air outlet of the parallel twin-screw extruder gearbox. Therefore, the two sealing sleeves can be directly mounted on the air inlet and air outlet of the parallel twin-screw extruder gearbox, and the two sealing sleeves form a seal by contacting the parallel twin-screw extruder gearbox; the length of the sealing sleeve is larger than the distance between the clamping plate and the parallel twin-screw extruder gearbox, and folding marks are processed on the surface of the sealing sleeve. As the driving assembly pushes the clamping plate and the side baffle to clamp the gearbox, the two sealing sleeves will first be mounted on the air inlet and air outlet, and then contact the surface of the gearbox. After that, as the clamping plate contacts the mounting plate at the bottom of the gearbox, the sealing sleeve will be forced to produce a certain amount of folding, thereby being compressed and forming a seal between the gearbox; The gearbox is made of metal. After the sealing sleeve contacts the gearbox, only the sealing sleeve will be squeezed and deformed. In order to avoid excessive squeezing and interference fit of the sealing sleeve, folding marks are set on the sealing sleeve. The sealing sleeve can form a seal by squeezing and fitting with the gearbox housing. The flow sensor 1 and the flow sensor 2 are used to detect the air intake of the air inlet and the air output of the air outlet respectively, and are displayed on the touch screen; The air pump is used to generate gas pressure and transport it to the air inlet of flow sensor 1 and sealing sleeve gear box through a hose; the air pump requires a controller to set data, and the touch screen can realize the data setting, start and stop of the air pump, and display the monitoring results of flow sensor 1 and flow sensor 2.

[0017] The present invention is further configured as follows: the pushing assembly comprises a gear, and the gear is meshed with a tooth plate 1 and a tooth plate 2; The tooth plate 1 is located on the top of the tooth plate 2, and the bottom of the tooth plate 1 does not contact the tooth plate 2; The top of the tooth plate 1 is fixedly connected to the testing platform; A cylinder is provided on one side of the tooth plate 2, and the cylinder is fixedly connected to the top of the inner cavity of the lower shell through a bracket, and the output end of the cylinder is fixedly connected to a fixing block fixedly connected to the tooth plate 2; A slide groove is provided on the back of the tooth plate 1, and a sliding block fixedly connected to the lower shell is slidably connected inside the slide groove.

[0018] The above technical solution is adopted, through the setting of the pushing component, to control the two sets of limit blocks on the top of the detection platform to exchange positions, that is, to drive the detection platform to move and reset; See also Figure 2 and Figure 3When the cylinder is started, the output end of the cylinder expands and contracts and pushes the fixed block to drive the toothed plate 2 to follow the movement; when the toothed plate 2 moves, the meshing relationship between it and the gear will drive the gear to rotate counterclockwise, and when the gear rotates counterclockwise, it will drive the toothed plate 1 to drive the detection platform to move, and when the detection platform moves, it will drive the two limit blocks on its top to move; the detection platform will move toward the support frame; If a parallel twin-screw extruder gearbox is placed between the two limit blocks on the left side of the top of the test bench, the two limit blocks on the left side will reach the position of the two limit blocks on the right side; the test can be carried out through the detection component; If a gearbox that has been tested is placed on the right side, the tested gearbox can be removed and a new gearbox to be tested can be placed to wait for the output end of the cylinder to be reset, so that the gear plate 2, gear, gear plate 1 and test bench can be reset and tested again through the test assembly; If the gearbox on the right is reset, the gearbox on the left can be removed and replaced with a new gearbox to be tested and wait for the next test. During the whole process, the unloading and loading of materials and the testing components do not need to be stopped, and the bee-down testing work can be carried out continuously.

[0019] The present invention is further configured as follows: the linkage assembly 1 includes a pulley 1, a rotating rod is fixedly sleeved inside the pulley 1, the rotating rod is also fixedly sleeved inside the gear, and the rotating rod is rotatably connected to the lower shell through a bearing; The pulley one is connected to the pulley two through a belt transmission, a rotating rod is fixedly sleeved inside the pulley two, the rotating rod is rotatably connected to the lower shell through a bearing, the rotating rod is located on one side of the tooth plate two, and the top end of the rotating rod passes through the top of the lower shell and is fixedly connected to a handle.

[0020] The above technical solution is adopted, through the setting of linkage component 1, it is used to manually rotate the gear when the cylinder fails, and drive the gear to rotate through manual operation, so that the gear drives the slider to drive the two sets of limit blocks on the top of the detection platform to alternate positions; When the cylinder fails, it is necessary to cut off the air supply, close the air source, and release the remaining pressure inside the cylinder so that its output end can be extended and retracted under manual action.

[0021] By rotating the rotating rod, the second pulley can be driven to rotate. The rotation of the second pulley can drive the rotating rod to rotate through the belt. The rotation of the rotating rod drives the first pulley inside it to rotate. The rotation of the first pulley can drive the toothed plate to drive the two sets of limit blocks on the top of the testing platform to exchange positions.

[0022] The present invention is further configured as follows: the linkage assembly 2 includes a bevel gear 1, the bevel gear 1 is meshed with a bevel gear 2, the interior of the bevel gear 2 is fixedly sleeved with a threaded sleeve, and the interior of the bevel gear 1 is fixedly sleeved with a connecting rod; The top end of the connecting rod passes through the top of the connecting shell and is fixedly connected with a handle, and the connecting rod is rotatably connected to the connecting shell through a bearing.

[0023] By adopting the above technical solution and setting the linkage component 2, the threaded rod can be manually extended and retracted when the driving motor fails.

[0024] When the driving motor fails, the connecting rod can be manually rotated clockwise or counterclockwise to make the connecting rod drive the bevel gear 1 to rotate. The rotation of the bevel gear 1 can drive the bevel gear 2 to drive the threaded sleeve to rotate. Since the threaded rod and the clamping plate are fixedly installed, and the clamping plate is restricted by the sliding connection between the two guide rods and the guide plate, when the threaded sleeve rotates clockwise, the threaded rod will extend from the inside of the threaded sleeve, thereby pushing the clamping plate to move toward the gear box; When the driving motor rotates counterclockwise, the threaded rod drives the clamping plate away from the gear box, and the threaded rod retracts into the inside of the threaded sleeve; In summary, linkage component 2 can avoid delays in detection when the drive motor fails and cannot rotate under electric drive.

[0025] In summary, the present invention has the following beneficial effects: The present invention can place two twin-screw extruder gear boxes at the same time by arranging a detection table component and a pushing component; when one gear box is being tested, the other gear box can wait for testing; when one gear box completes testing, the other gear box can be moved to the testing position and actively connected to perform sealing testing under the cooperation of the driving component, the auxiliary component and the testing component; at this time, the gear box that has completed the testing can be unloaded and a new gear box to be tested can be replaced; the two gear boxes can be used alternately, and the testing component can continuously test the gear box without stopping the machine; By setting the driving assembly, the test bench assembly and the test assembly, the air inlet and the air outlet of the gearbox can be automatically connected and sealed, so as to facilitate rapid testing; By equipping the push component and the drive component with manual operation structure linkage component one and linkage component two, manual operation can be performed in the event of a cylinder failure in the push component and a drive motor failure in the drive component, thereby preventing the cylinder or drive motor failure from affecting the detection work of the gear box.

The rotation of the bevel gear 1 81 can drive the bevel gear 2 82 to drive the threaded sleeve 33 to rotate. Since the threaded rod 34 and the clamping plate 41 are fixedly installed, and the clamping plate 41 is restricted by the sliding connection between the two guide rods 42 and the guide plate 43, when the threaded sleeve 33 rotates clockwise, the threaded rod 34 will extend from the inside of the threaded sleeve 33, thereby pushing the clamping plate 41 to move toward the gear box; when the drive motor 32 rotates counterclockwise, the threaded rod 34 drives the clamping plate 41 away from the gear box, and the threaded rod 34 retracts into the inside of the threaded sleeve 33; in summary, the linkage component 2 8 can avoid the delay of detection when the drive motor 32 fails and cannot rotate under electric drive.

[0037] Working principle: When in use, first place the gear box between two limit blocks 23 on the top of the testing table 21; And through the driving component 3, auxiliary component 4, detection component 5, push component 6, detection table component 2 and other structures to cooperate with the mobile gear box (see Figure 1 middle gearbox position); At this time, the space between the two limit blocks 23 on the left side is empty, and the gear can be placed between the two limit blocks 23 by the manipulator, and one side of the gear box is pushed between the two limit blocks 23, waiting for the sealing test; After the gearbox on the right is inspected, the driving component 3 drives the auxiliary component 4 to drive the inspection component 5 away from the gearbox; The output end of the cylinder 64 extends out, and starts to push the fixed block 65 to drive the gear plate 2 63 to move. The gear plate 2 63 moves to drive the gear 61 to rotate counterclockwise. The gear 61 drives the gear plate 1 62 to move under the guidance of the slide groove 66 and the slider 67. The movement of the gear plate 1 62 can drive the detection platform 21 and the limit block 23 on its top to move. Then the gearbox on the left side of the testing table 21 will reach the position of the gearbox previously tested; the gearbox that has completed the test will continue to move to the right; the gearbox that has completed the test can be unloaded at this time, and a new gearbox to be tested can be replaced and wait for the next test; After the gearbox on the left side is in place, the driving motor 32 starts to drive the threaded sleeve 33 to rotate, and the threaded sleeve 33 drives the threaded rod 34 to extend and push the clamping plate 41 to move toward the gearbox, and clamp the gearbox through the cooperation with the side baffle 22; at the same time, the two sealing sleeves 58 will first be set on the air inlet and air outlet of the gearbox, and one side of the two sealing sleeves 58 will also contact the gearbox and be squeezed under the movement of the clamping plate 41, and completely form a seal through contact with the surface of the gearbox; After that, the air pump 53 starts to input the gas through the hose 54 into the flow sensor 1 56, the sealing sleeve 58, and the air inlet of the gear box; the flow sensor 1 56 will detect the air intake and display it through the touch screen 52. After the gas enters the gear box, it is discharged through the air outlet. The air outlet is detected by the flow sensor 2 57 and displayed on the touch screen 52. The air intake detected by the flow sensor 1 56 and the air outlet detected by the sealing sleeve 58 are compared to obtain the sealing test result. After the test is completed; the drive motor 32 is started to make its output end rotate in the opposite direction to the last time, and the threaded sleeve 33 is driven to rotate through the coupling to drive the threaded rod 34 to drive the clamping plate 41, the detection component 5, etc. away from the gear box; The cylinder 64 is started again, and its output end retracts to pull the fixed block 65 and the gear plate 2 63 to reset. When the gear plate 2 63 is reset, the driving gear 61 rotates clockwise, and the gear 61 drives the gear plate 1 62 to drive the detection table 21 and the gear box on the top to reset; At this time, the new gearbox replaced on the right side will reach the detection position, and the drive component 3 and the detection component 5 can work to detect the gearbox; The reset gearbox that has completed the inspection is unloaded and replaced with a new gearbox to be inspected; Just repeat the test as above; If the cylinder 64 or the drive motor 32 fails to work properly, during their maintenance, their replacement mechanism linkage assembly 1 7 and linkage assembly 2 8 can be manually operated, thereby eliminating the need to wait for the maintenance time of the cylinder 64 or the gear plate 1 62.
