Description

Technical Field

[0001] This utility model relates to the field of hydraulic filter processing, and in particular to a filter screen folding mechanism. Background Technology

[0002] The function of a hydraulic filter is to filter out various impurities in a hydraulic system. These impurities mainly come from mechanical impurities remaining in the hydraulic system after cleaning, such as rust, casting sand, welding slag, iron filings, paint residue, paint flakes, and cotton fibers; external impurities entering the hydraulic system, such as dust entering through the filler neck and dust seals; and impurities generated during operation, such as fragments formed by seals under hydraulic pressure, metal powder generated from relative wear of moving parts, and colloids, asphalt, and carbon deposits produced by oil oxidation. Filter screens are used to filter out these blockages. Common types include suction filters and return filters, located at the pump's suction port and the system's return port within the oil tank, respectively. There are also filters located in the pipeline circuit.

[0003] However, existing filter screen folding technology leaves debris on the surface of the screen after processing, which, if not cleaned promptly, will affect the folding process. Furthermore, changing rolls after folding a single filter screen requires cutting the screen and fixing the resulting free end to the roller, which is cumbersome. Therefore, it is necessary to improve this structure to overcome these shortcomings. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a filter screen folding mechanism. This utility model is achieved through the following technical solution:

[0005] A filter screen folding mechanism includes a support, a storage roller, and a reversing roller. The storage roller and the reversing roller are rotatably mounted on the support. The mechanism also includes a pressing roller assembly, a winding roller, and a control mechanism. The winding roller is rotatably connected to the support and has a mating plane with a snap-fit ​​strip. The control mechanism is slidably mounted on the support and includes two clamping blocks that can move closer or further apart. A placement groove is provided on the side of the clamping blocks that moves away from each other. A fixing block is detachably mounted in the placement groove, and a snap-fit ​​groove is provided on the fixing block. The shape of the snap-fit ​​groove corresponds to the shape of the snap-fit ​​strip. A brush is also fixedly mounted on the support.

[0006] In the above technical solution: the bracket is used to set and support the other components; the storage roller is used to store raw materials; the reversing roller is used to guide and change the direction of filter screen conveying; the brush is used to brush off debris on the filter screen; the clamping roller group is used to partially clamp and prevent the filter screen from retracting in the opposite direction; the take-up roller is used to take up the folded filter screen; the control mechanism is used to clamp the filter screen before cutting and to connect the end to the new take-up roller after rewinding; the mating plane is used to set the snap-fit ​​strip; the snap-fit ​​strip is used to cooperate with the snap-fit ​​groove to fix the end of the filter screen; the clamping block is used to clamp the end of the filter screen, and the placement groove is used to place the fixing block; the fixing block can be separated so that after the snap-fit ​​strip and the snap-fit ​​groove are mated, the fixing block will be fixed on the take-up roller.

[0007] A further feature of this invention is that the control mechanism includes a connecting frame, a cylinder, and a motor. The connecting frame is rotatably connected to the bracket. The cylinder is fixedly mounted on the connecting frame, and the output direction of the cylinder is vertically upward. The motor is fixedly mounted on the output end of the cylinder, and a finger cylinder is fixedly connected to the output end of the motor. The two clamping blocks are respectively fixed on the two grippers of the finger cylinder.

[0008] In the above technical solution: the connecting frame is used to set the other components of the control mechanism; the cylinder is used to realize the up and down movement of the finger cylinder to avoid impacting the filter screen during the movement; the motor is used to rotate the finger cylinder so that the filter screen can cover the snap-fit ​​groove on the fixing block when the finger cylinder rotates, so that the snap-fit ​​groove and snap-fit ​​strip can cooperate to fix the filter screen.

[0009] A further feature of this invention is that the placement groove and the fixing block are magnetically connected.

[0010] In the above technical solution, the placement slot and the fixing block are magnetically connected, which allows them to be easily separated and installed.

[0011] A further feature of this invention is that the pressing roller assembly includes a bottom roller and a pressure roller, the bottom roller is rotatably connected to the bracket, and the pressure roller is in contact with the bottom roller.

[0012] In the above technical solution: the bottom roller and the pressure roller are in contact to avoid pulling back the cut filter screen due to the weight of the storage roller being greater than the clamping force between the two clamping blocks.

[0013] A further feature of this invention is that the pressure roller is covered with a flexible layer.

[0014] In the above technical solution: the flexible layer is used to increase the friction between the bottom roller and the pressure roller.

[0015] A further feature of this invention is that the number of the mating planes is two, which are respectively disposed at both ends of the side of the take-up roller.

[0016] A further feature of this invention is that the number of control mechanisms is two, respectively disposed on both sides of the take-up roller.

[0017] In the above technical solution, there are two docking planes and two control mechanisms, so that the filter screen and the winding roller can be firmly fixed after the two are combined.

[0018] This utility model discloses a filter screen folding mechanism, which, compared with the prior art:

[0019] 1. This utility model, by setting up a control mechanism and a docking plane, enables the filter screen end to be clamped and fixed on the new take-up roller after the roll is changed, thereby saving the time of roll changing;

[0020] 2. This utility model also includes a brush to remove debris from the filter screen, so as to avoid debris remaining in the filter screen after winding, which would affect the performance. Attached Figure Description
