Description

Technical Field

[0001] This utility model relates to the technical field of filter element production equipment, specifically to a filter element cutting device for a winding machine. Background Technology

[0002] In the existing production process of wound filter elements, after the filter element is wound, it needs to be removed from the winding machine and then transferred to the cutting machine for length cutting. This separate cutting method has obvious drawbacks: it requires additional manual handling and equipment operation, which increases time costs and manpower input; multiple transfers may damage the filter element and affect product quality; the purchase, maintenance and space occupation of the independent cutting machine further increases production costs. Therefore, there is an urgent need for a cutting device that can be directly integrated into the winding machine to realize the integrated operation of filter element winding and cutting. Utility Model Content

[0029] Example 1

[0030] Appendix Figure 1 The present invention provides a filter element cutting device for a winding machine, comprising a cylinder 1, a base plate 2, a slider 3, a guide rail 4, a knife holder 5, a clamping plate 6, and a blade 7.

[0031] The slider 3 is installed at the bottom of the base plate 2;

[0032] The slider 3 is slidably connected to the guide rail 4;

[0033] The guide rail 4 is fixed on the winding machine; there are two guide rails 4 arranged in parallel, the slider 3 corresponds one-to-one with the guide rail 4, and the base plate 2 slides smoothly on the guide rail 4 through the slider 3;

[0034] The tool holder 5 is mounted on the base plate 2 by bolts;

[0035] The blade holder 5 has U-shaped bolt holes; the U-shaped bolt holes extend along the filter element cutting direction. By adjusting the position of the blade holder 5 on the base plate 2, the distance between the two blades 7 can be changed to adapt to the cutting requirements of filter elements of different lengths.

[0036] The blade 7 is fixed to the blade holder 5 by the clamping plate 6 and bolts; there are two clamping plates 6, located on both sides of the blade 7, and the blade 7 is clamped and fixed to the blade holder 5 by bolts to prevent the blade 7 from deforming during cutting; the blade 7 is made of high-speed steel, with a blade angle of 30°-45° and a blade length greater than the outer diameter of the filter element to ensure complete cutting of the filter element.

[0037] The piston rod of the cylinder 1 is connected to the base plate 2 and is used to drive the base plate 2 to move back and forth along the guide rail 4. The cylinder 1 is a double-acting cylinder 1, and its extension and retraction are controlled by a solenoid valve to control the reciprocating motion of the base plate 2 to complete the single or multiple cutting of the filter element.

[0038] The filter element cutting device of the winding machine is fixedly installed on the frame of the winding machine and located on one side of the filter element winding station. The cutting position of the blade 7 is perpendicular to the winding axis of the filter element.

[0039] The specific steps for installing and using the device include the following:

[0040] 1. Device Installation

[0041] Two guide rails 4 are fixed parallel to each other on the frame of the winding machine, located on one side of the filter element winding station. Two sliders 3 are installed at the bottom of the base plate 2. The sliders 3 are slidably connected to the guide rails 4 to ensure that the base plate 2 can move smoothly along the guide rails 4. The cylinder 1 is fixed on the winding machine by a bracket. The piston rod of the cylinder 1 is connected to the base plate 2 and connected to the air source and solenoid valve through an air pipe.

[0042] 2. Installation of the tool holder 5 and the blade 7

[0043] The blade holder 5 is placed on the base plate 2. The bolt at the bottom of the blade holder 5 passes through the U-shaped bolt hole and connects to the threaded hole on the base plate 2. According to the required filter element length, loosen the bolt and slide the blade holder 5 along the U-shaped bolt hole to adjust the distance between the two blades 7. After adjustment, tighten the bolt to fix the blade holder 5. Place the blade 7 in the mounting groove of the blade holder 5, and use the blade clamping plate 6 to fit on both sides. Use the bolt to clamp the blade clamping plate 6 to the blade holder 5 to fix the blade 7 on the blade holder 5, ensuring that the blade edge of the blade 7 is perpendicular to the winding axis of the filter element.

[0044] 3. Cutting operation

[0045] After the filter element is wound on the winding machine, the control system sends a signal to the solenoid valve, which controls the piston rod of cylinder 1 to extend and push the base plate 2 to move forward along the guide rail 4. The blade 7 moves with the base plate 2 and cuts the filter element. After the cutting is completed, the piston rod of cylinder 1 retracts, and the base plate 2 drives the blade 7 back to the initial position, waiting for the next cutting command.

[0046] This application discloses a filter element cutting device for a winding machine, which is integrated into the winding machine to achieve integrated winding and cutting. It eliminates the filter element handling and secondary clamping steps, saving more than 50% of time and significantly improving production efficiency. It reduces manual intervention, lowers labor intensity, avoids filter element damage caused by manual handling, and improves product quality stability. The structure is simple and compact. The spacing of the blades 7 can be flexibly adjusted through the U-shaped bolt holes, which can adapt to the cutting of various specifications of filter elements and has strong versatility. The clamping plate 6, together with the bolts, clamps the blades 7 to ensure the stability of the blades 7 during the cutting process and avoids cutting accuracy deviation caused by blade deformation.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
