Description

Technical Field

[0001] The invention relates to the technical field of filter element processing, and in particular to a method and a device for adjusting the width of a clamp used for filter element processing. Background Art

[0002] It is a professional term for filtering and purification functions. In order to purify the resources of the original fluid and the simple device for separating the resources, the filter element is now mainly used in oil filtration, air filtration, water filtration and other filtration industries.

[0003] At present, during the processing of the filter element, it is usually necessary to use a clamp to clamp and fix it. However, the existing filter element clamp is usually composed of two baffles and a bottom plate. The baffle is vertically fixed on the same surface of the bottom plate to form a U shape, and there is a long hole on the bottom plate. The fixed baffle and the screw move along the long hole. After the baffle moves to the appropriate position, tighten the screw to complete the adjustment. The cumbersome and difficult adjustment is a disadvantage of this clamp. Another disadvantage is that the current clamp is fixed in the installation orientation and is difficult to be installed on the conveyor belt for recycling, which makes the overall use of the clamp time-consuming and labor-intensive, and the accuracy is not high. Therefore, a method and device for adjusting the width of the clamp for filter element processing are proposed to solve the above problems. Summary of the invention

[0006] Preferably, the specifications of the inner sides of the first spline hole synchronization wheel and the second spline hole synchronization wheel are adapted to the specifications of the outer side of the first spline shaft, and the specifications of the inner sides of the third spline hole synchronization wheel and the fourth spline hole synchronization wheel are adapted to the specifications of the outer side of the second spline shaft.

[0007] Preferably, the first baffle and the second baffle have the same orientation, the third baffle and the fourth baffle have the same orientation, the first baffle and the second baffle are opposite to the third baffle and the fourth baffle, and the first baffle, the second baffle, the third baffle and the fourth baffle are all L-shaped.

[0008] Preferably, the adjusting member includes a bidirectional screw fixedly connected to the output shaft of the third servo motor, the outer sides of the bidirectional screw are respectively threadedly connected with a first screw nut and a second screw nut, the outer side of the first screw nut is fixedly connected with a group of first fixing plates, the outer side of the second screw nut is fixedly connected with a group of second fixing plates, and the ends of the first fixing plate and the second fixing plate away from the bidirectional screw are fixedly connected with a fork.

[0009] Preferably, the threads on the inner walls of the first screw nut and the second screw nut are symmetrically distributed and matched with the threads on the outer side of the bidirectional screw.

[0010] Preferably, the two first fixing plates and the second fixing plates are both U-shaped, and the ends of the four fork-shaped devices are used to limit the first spline hole synchronous wheel and the third circular hole synchronous wheel, the second spline hole synchronous wheel and the fourth circular hole synchronous wheel, the second circular hole synchronous wheel and the fourth spline hole synchronous wheel, the first circular hole synchronous wheel and the third spline hole synchronous wheel that are in contact with each other on the same side.

[0012] The method for adjusting the width of the clamp used for processing the filter element comprises the following steps: S1. When the first servo motor is started and drives the first spline shaft to rotate, the first spline hole synchronous wheel and the second spline hole synchronous wheel can be driven to rotate accordingly, so as to drive the first drive structure and the second drive structure to move in the same direction, so as to adjust the first baffle and the second baffle to move in the direction parallel to the horizontal plane. When the second servo motor is started and drives the second spline shaft to rotate, the third spline hole synchronous wheel and the fourth spline hole synchronous wheel can be driven to rotate, so as to drive the third baffle and the fourth baffle to move in the direction parallel to the horizontal plane. The machine controls the spacing between the first baffle, the second baffle and the third baffle and the fourth baffle, so as to realize the adjustment of the overall clamp length. S2, by starting the third servo motor, driving the bidirectional screw to rotate, the first screw nut and the second screw nut can be driven to move and adjust in opposite directions, and the two first fixing plates, the second fixing plates and the fork-shaped device as well as the spline hole synchronous wheel and the round hole synchronous wheel attached on the same side can be driven to adjust the spacing, thereby realizing the width adjustment of the overall clamp; S3.

[0017] 5. The method and device for adjusting the width of the clamp used for processing the filter element can meet the new production requirements by only modifying the human-machine interface program or replacing some hardware equipment when the production process or product requirements change, thereby improving the versatility and adaptability of the equipment.

In order to avoid the equipment being unable to query historical data when quality problems occur, the present invention can quickly trace back to specific production batches and adjustment parameters, which is convenient for enterprises to find out the root cause of the problem, take corresponding improvement measures, and improve the product quality traceability and after-sales service level.

[0036] The method for adjusting the width of the clamp used for processing the filter element comprises the following steps: S1, when the first servo motor 19 is started, the first spline shaft 17 is driven to rotate, which can drive the first spline hole synchronous wheel 3 and the second spline hole synchronous wheel 7 to rotate, so as to drive the first drive structure 2 and the second drive structure 6 to move in the same direction, so as to adjust the first baffle 1 and the second baffle 5 to move in the direction parallel to the horizontal plane. When the second servo motor 20 is started, the second spline shaft 18 is driven to rotate, and the third spline hole synchronous wheel 11 and the fourth spline hole synchronous wheel 15 are driven to rotate, the third drive structure 10 and the fourth drive structure 14 can be driven to move, so as to drive the third baffle 9 and the fourth baffle 13 to move in the direction parallel to the horizontal plane.

After the horizontal positions of the first baffle 1, the second baffle 5, the third baffle 9 and the fourth baffle 13 are adjusted, the first servo motor 19 and the second servo motor 20 can be kept running synchronously and at the same speed to realize the circulation of the clamp, and the first servo motor 19, the second servo motor 20 and the third servo motor 21 are respectively controlled by the three first servo drive modules 28, the second servo drive module 29 and the third servo drive module 30 on the human-machine interface 27. The operator only needs to input numerical values ​​on the human-machine interface 27 to control the clamp width at will and accurately.

When the horizontal positions of the first baffle 1, the second baffle 5, the third baffle 9, and the fourth baffle 13 meet the requirements, the third circular hole synchronous wheel 12 and the fourth circular hole synchronous wheel 16 move simultaneously to achieve parallel transportation of the clamp. After the overall clamping meets the requirements, the first servo motor 19 and the second servo motor 20 can be kept running synchronously at the same speed to achieve the circulation of the clamp. During the process, the operator only needs to perform convenient data entry on the human-machine interface 27 to achieve automatic clamp adjustment without excessive manual operation, saving labor costs, and the entire clamp can be operated in an automated working mode through the operation method, which can improve the clamp accuracy, improve efficiency, and greatly save production time.
