The use of a feeler gauge for repeated measurement increases the workload and time consumption. The utility model provides a filter cutting drum wheel of a rolling machine.

[0031] As shown in Figure 1 , the filter cutting drum wheel of the rolling machine comprises a drum wheel body 1 and a rotating positioning block 2;As shown in Figure 2 , the drum wheel body 1 has a locking ring 11 and a positioning seat 12, the locking ring 11 is used for sleeving and locking on the transmission shaft, the positioning seat 12 is located at the axial outer end of the locking ring 11, and the center of the positioning seat 12 has a threaded hole;As shown in Figure 4As shown, the rotating positioning block 2 has a rotating ring 21 with external threads and a positioning column 22 arranged in the core of the rotating ring 21 for abutting against the end of the transmission shaft.

[0032] The drum wheel body 1 adds a positioning seat 12 with internal threads on the basis of the locking ring 11 of the original drum wheel. The locking ring 11 is designed to be closely sleeved on the transmission shaft, and the locking mechanism ensures that it will not loosen during work. The positioning seat 12 is located at the axial outer end of the locking ring 11, and the center is equipped with a threaded hole to facilitate cooperation with the rotating positioning block 2. The rotating positioning block 2 includes an external threaded rotating ring 21, which is installed in the threaded hole of the positioning seat 12, so that the rotating positioning block 2 can be screwed in or out of the positioning seat 12 to adjust the depth of the transmission shaft inserted into the filter cutting drum wheel, achieving rapid axial adjustment. The positioning column 22 arranged in the rotating block can abut against the end of the transmission shaft. A precise adjustment is made at the first use, and then the filter cutting drum wheel is only pushed to the bottom during installation, without the need for axial adjustment, avoiding the cumbersome steps during installation, eliminating the need for repeated measurements using a plug gauge, eliminating the influence of the subjective feelings of maintenance personnel on the adjustment results, solving the problem of low success rate of filter cutting drum wheel installation, achieving rapid and accurate installation of the filter cutting drum wheel, and greatly improving work efficiency.

[0033] The positioning seat 12 is a complete circular ring, and a separation groove 111 is arranged between the locking ring 11 and the positioning seat 12, the separation groove 111 is arranged along the circumference of the locking ring 11, and the part outside the separation groove 111 on the entire circumference connects the locking ring 11 and the positioning seat 12.

[0034] As shown in Figure 2 , Figure 3 The positioning seat 12 is designed as a complete circular ring shape, which can provide a larger contact area for connecting with the locking ring 11, improving the overall stability and durability. A separation groove 111 is arranged between the locking ring 11 and the positioning seat 12, and the separation groove 111 is arranged along the circumference of the locking ring 11. The separation groove 111 separates the complete positioning seat 12 and the locking ring 11, so that the locking ring 11 can realize the locking function.

[0035] The locking ring 11 is also provided with a locking groove 112, which is parallel to the axial direction of the locking ring 11, so that the complete locking ring 11 has a proper gap in the circumferential direction. The locking groove 112 is connected with the partition groove 111, so that the locking ring 11 can effectively release part of the stress when being fastened, and the locking groove 112 cooperates with the partition groove 111, so that the locking ring 11 can be reliably locked on the transmission shaft.

[0036] On both sides of the locking ring 11, one side is provided with a threaded hole, and the other side is provided with a through hole. Through this design, the fastening screw 3 can pass through the through hole on one side and be smoothly installed into the threaded hole on the other side, thereby forming a stable connection, ensuring the safety and stability of the filter cutting drum under high load working conditions.

[0037] As shown in Figure 4 The positioning column 22 is designed as two columns and arranged in a cross shape (90° cross), and the intersection point is located at the center of the rotating ring 21. Through the cross design of the two positioning columns 22, the filter cutting drum transmission shaft can be resisted to achieve more accurate positioning. At the same time, this design also facilitates the rotation of the rotating ring 21, realizes quick installation and adjustment, so that the maintenance personnel can quickly complete the installation and disassembly of the drum without affecting the cutting accuracy. The positioning column 22 is a cylindrical shape, of course, it can be understood that a prism or an elliptical column can also be used, as long as it can achieve positioning.

[0038] The outer end surface of the positioning seat 12 is provided with a wheel body scale 122. These scales are arranged in a circumferential radiation manner with the axis of the positioning seat 12 as the center. Such a design enables the operator to conveniently and accurately adjust the cutting position, ensuring the accuracy during the cutting process. Correspondingly, the outer end surface of the rotating ring 21 is also provided with a positioning scale 23. The cooperation between the two provides an intuitive reference, which helps to accurately adjust during operation. The axial depth change when the rotating ring 21 rotates one grid is calculated by the screw pitch, so that the operator can quickly grasp the appropriate position during equipment adjustment, thereby improving work efficiency and reducing the operation failure rate.

[0039] The outer circumference of the positioning seat 12 is provided with a tightening assembly, which is located at the central position of the axial direction of the positioning seat 12 and is specially used for tightening the rotating positioning block 2. This design enables the rotating positioning block 2 to be quickly and stably fixed during installation, ensuring that it will not loosen during the cutting process. The central positioning design of the tightening assembly makes the force application more uniform, thereby effectively preventing structural damage caused by excessive local stress. This design not only enhances the stability of the equipment, but also prolongs the service life, providing a reliable guarantee for the subsequent production process.

[0040] As shown in Figure 2 ,Figure 3 As shown, the positioning seat 12 is radially provided with a clamping groove 121 and a clamping hole 123, and the clamping groove 121 is located radially inside the clamping hole 123. The clamping assembly is composed of a clamping screw 4 and a clamping block 5, as shown in Figure 5 As shown, the inner side surface of the clamping block 5 is a threaded surface matched with the external thread of the rotating ring 21, which ensures that the clamping block 5 can effectively abut against the rotating ring 21 during the clamping process, providing a stable fixing effect. As shown in Figure 6 As shown, the clamping screw 4 is installed in the clamping hole 123 through the thread, and the inner end thereof abuts against the outer side surface of the clamping block 5. Through this structure, reliable fixation of the rotating ring 21 can be achieved, effectively improving the safety and stability of the equipment.

[0041] In this embodiment, the clamping groove 121 is designed as a square groove, and the clamping block 5 is designed as a square block matched with the clamping groove 121. This matching design can effectively prevent the clamping block 5 from rotating during the clamping process, thereby avoiding the problem that the threaded surface of the clamping block 5 cannot engage with the external thread of the rotating ring 21, causing damage to the thread of the rotating ring 21. The combination of the square groove and the square block-shaped clamping block 5 enables the clamping block 5 to remain in a fixed position during the clamping operation, thereby ensuring stable fixation of the rotating ring 21.

[0042] The use steps of the filter cutting drum are as follows:

[0043] 1. When used for the first time, loosen the clamping screw 4, and push the filter cutting drum body 1 into the filter cutting drum transmission shaft.

[0044] 2. Place the cutter into the cutter groove, adjust the axial position of the filter cutting drum by rotating the rotating positioning block 2 in the positioning seat 12, so that it is in the best position for cutting.

[0045] 3. Tighten the clamping screw 4 and adjust the circumferential intersection position of the filter cutting drum, and tighten the fastening screw 3.

[0046] 4. When disassembled and installed subsequently, only need to push the filter cutting drum to the bottom, adjust the intersection position, and tighten the fastening screw 3.

[0047] When used for the first time, a precise adjustment is made, and the rotating positioning block 2 is fixed so that it cannot rotate. When installed subsequently, only need to push the filter cutting drum to the bottom, adjust the intersection position, and fix the fastening screw 3, without the need for axial adjustment. This simplifies the installation and disassembly process of the drum, enables quick and precise positioning and disassembly, improves work efficiency, reduces labor intensity, saves production time, reduces raw material consumption, and improves product quality.

[0048] The utility model discloses above although the specific embodiment of the utility model has been described in conjunction with the drawing, is not the limit to the protection scope of the utility model, and the person skilled in the art should understand that on the basis of the technical scheme of the utility model, various modifications or deformation that the person skilled in the art can make without paying creative labour are still within the protection scope of the utility model.
