Description

Technical Field

[0001] This utility model belongs to the field of sheet metal cutting, and in particular relates to an automatic slitting disc assembly. Background Technology

[0002] This research focuses on automated slitting equipment for metal coils and sheets in the construction and sheet metal manufacturing industries. Currently, the automated sheet metal slitting process in these industries primarily utilizes disc cutters to continuously slit metal coils or sheets to obtain the required width. Subsequently, the length is cut to a fixed length as needed. Traditionally, the position adjustment of the disc cutter relies mainly on manual operation to achieve slitting of sheets to different widths. This technology has been used for decades, exhibiting low adjustment efficiency, outdated production technology, and relatively high technical requirements for operators. Summary of the Invention

[0003] In view of this, the present invention aims to propose an automatic slitting disc assembly to solve the problem that, in the prior art, when cutting plates of different widths, the relative position of the disc cutter needs to be manually adjusted, which results in low adjustment and unstable adjustment quality.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] An automatic slitting disc assembly includes a backstop, a slitting disc base, a disc slitting blade, and a sliding bearing. The slitting disc base is slidably connected to the periphery of a drive shaft via the sliding bearing. The disc slitting blade is disposed on the periphery of the slitting disc base. A backstop is fitted inside the slitting disc base. The backstop is a one-way self-locking structure. When the backstop rotates in the release direction, an external force can push the backstop and the slitting disc base to slide axially along the drive shaft. When the backstop rotates in the self-locking direction, the slitting disc base is locked to the periphery of the drive shaft by the backstop.

[0006] Furthermore, dust seals are provided at both ends of the sliding bearing, and the dust seals are used for sealing between the cutting blade holder and the upper and lower drive shafts.

[0007] Furthermore, the automatic slitting disc assembly also includes a pre-tightening toothed disc, and the pre-tightening toothed disc is provided with a first through hole, the outer periphery of the locking part is located in the first through hole, and the locking part is used to fix the position between the pre-tightening toothed disc and the slitting disc seat.

[0008] Furthermore, a positioning plate is provided on one side of the pre-tightening gear plate, and a second through hole is provided on the positioning plate. The outer periphery of the locking part is located in the second through hole. The positioning plate is located on one side of the pre-tightening gear plate, and the other side of the pre-tightening gear plate can abut against the slitting blade plate seat.

[0009] Furthermore, one end of the slitting disc seat is provided with a blind groove, the backstop is sleeved in the blind groove, and one end of the backstop is provided with a positioning locking block, the other end of the backstop abuts to the bottom of the blind groove, and the outer periphery of the positioning locking block is sleeved on the inner ring of the blind groove.

[0010] Furthermore, a pressure ring and a rubber ring are respectively provided on both sides of the disc slitting blade. The pressure ring is fixedly connected to the slitting blade disc seat through a locking part, and the outer diameter of the rubber ring is smaller than the outer diameter of the disc slitting blade.

[0011] Furthermore, the inner ring of the rubber ring is fitted onto the slitting blade disc seat.

[0012] Furthermore, the backstop includes an outer ring, centering rollers, an elastic retainer, and clamping wedges. Multiple centering rollers are arranged circumferentially inside the outer ring, and each centering roller is rotatably connected to the periphery of the upper or lower drive shaft. The outer ring is sleeved around the inner ring of the slitting disc seat. An elastic retainer is provided between the outer ring and the upper or lower drive shaft. Multiple mounting grooves are evenly distributed circumferentially on the elastic retainer. A clamping wedge is provided in each mounting groove, and the clamping wedge can rotate within the mounting groove. The two ends of the clamping wedge can respectively abut against the inner circumference of the outer ring and the periphery of the upper or lower drive shaft.

[0013] Furthermore, the two sides of the clamping wedge are pressed against each other by a mounting groove sidewall, causing one end of the clamping wedge to abut against the outer periphery of the drive shaft. This allows the clamping wedge to be installed inside the outer ring by an elastic retainer, and the elastic retainer continuously presses the clamping wedge firmly onto the drive shaft, so that the clamping wedge can be pre-tightened on the outer periphery of the drive shaft and continuously clamp the drive shaft.

[0014] Furthermore, a stop post is provided on each side of the clamping wedge, and the stop post can limit the relative position of the clamping wedge.

[0015] Furthermore, the clamping wedge has a follow-up arc at one end near the periphery of the upper or lower drive shaft, and the follow-up arc increases sequentially along the rotation direction of the upper or lower drive shaft.

[0016] Compared with the prior art, the automatic slitting disc assembly of this utility model has the following advantages: by utilizing the one-way self-locking characteristic of the backstop, the automatic locking and unlocking operation of the slitting disc assembly is realized, and the slitting disc seat can slide on the drive shaft. It is connected to the slitting disc seat through the adjusting gear plate on the external device, and the axial position adjustment of the slitting disc seat can be realized through the external device. All of the above actions can be set by computer parameters and executed automatically, thereby realizing automated, intelligent and unmanned high-efficiency production. Attached Figure Description

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] An automatic slitting disc assembly is mounted on an upper drive shaft 100 and a lower drive shaft 200, such as... Figure 1As shown, in this embodiment, two automatic slitting disc assemblies are respectively arranged on the upper drive shaft 100 and the lower drive shaft 200. The two automatic slitting disc assemblies form a cutting structure for the plate 400. An adjusting gear 300 is arranged on one side of the upper drive shaft 100 or the lower drive shaft 200. In this embodiment, the adjusting gear 300 is arranged on one side of the upper drive shaft 100. The mounting structure of the adjusting gear 300 is prior art. The adjusting gear 300 needs to be mounted on the drive motor. The drive motor is fixedly mounted on one end of the support plate. A prior art linear module is arranged on the other end of the support plate. The middle of the support plate is rotatably connected to a fixed position. Its working principle is that the movable end of the linear module can push the drive motor and the adjusting gear 300 to rotate along the middle of the support plate, so that the adjusting gear 300... The adjusting gear 300 can approach or move away from the automatic slitting disc assembly. After the adjusting gear 300 approaches and abuts against the outer periphery of the automatic slitting disc assembly, the adjusting gear 300 can drive the automatic slitting disc assembly to rotate. As the automatic slitting disc assembly rotates, the inner ring of the automatic slitting disc assembly will hug the outer periphery of the upper drive shaft 100 or the lower drive shaft 200, thereby positioning the automatic slitting disc assembly on the outer periphery of the upper drive shaft 100 or the lower drive shaft 200. Before the automatic slitting disc assembly hugs the outer periphery of the upper drive shaft 100 or the lower drive shaft 200, the adjusting gear 300 is also connected to a prior art pushing module, which can push the adjusting gear 300 and the automatic slitting disc assembly to slide axially along the upper drive shaft 100 or the lower drive shaft 200.

[0030] like Figures 1-5 As shown, an automatic slitting disc assembly includes a backstop 1, a slitting disc base 2, a disc slitting blade 3, and a sliding bearing 4. The slitting disc base 2 is slidably connected to the outer periphery of the upper drive shaft 100 or the lower drive shaft 200 via the sliding bearing 4. The backstop 1 is fitted inside the inner ring of the slitting disc base 2, and the inner ring of the backstop 1 can contact the outer periphery of the upper drive shaft 100 or the lower drive shaft 200. The disc slitting blade 3 is arranged on the outer periphery of the slitting disc base 2. Utilizing the one-way self-locking characteristic of the backstop 1, the automatic locking and unlocking operation of the disc slitting blade assembly is realized. The slitting disc base 2 can slide on the drive shaft and is connected to the slitting disc base 2 via an adjusting gear 300 on an external device. The axial position of the slitting disc base 2 can be adjusted via the external device. All of the above actions can be set with parameters by computer and executed automatically, thereby realizing automated, intelligent, and unmanned high-efficiency production.

[0031] Dust rings 5 ​​are provided at both ends of the sliding bearing 4. The dust rings 5 ​​are used to seal between the cutting blade holder and the upper drive shaft 100 and the lower drive shaft 200 to prevent dust or debris from entering this part and hindering the sliding between the sliding bearing 4 and the upper drive shaft 100 and the lower drive shaft 200.

[0032] like Figure 1 indivual Figure 2As shown, an automatic slitting disc assembly further includes a pre-tightening toothed disc 6, and the pre-tightening toothed disc 6 is provided with a first through hole. The outer periphery of the locking part 7 is located in the first through hole, and the locking part 7 is used to fix the position between the pre-tightening toothed disc 6 and the slitting disc seat 2. The outer periphery of the pre-tightening toothed disc 6 can engage with the adjusting toothed disc 300 so that the adjusting toothed disc 300 can drive the pre-tightening toothed disc 6 and the slitting disc seat 2 to rotate. The locking part 7 is a conventional metal locking bolt.

[0033] To improve installation accuracy and convenience, a positioning plate 8 is provided on one side of the pre-tightening gear plate 6. The positioning plate 8 has a second through hole, and the outer periphery of the locking part 7 is located in the second through hole. The positioning plate 8 is located on one side of the pre-tightening gear plate 6, and the other side of the pre-tightening gear plate 6 can abut against the slitting blade plate seat 2. One end of the slitting blade plate seat 2 is provided with a blind groove, and the backstop 1 is sleeved in the blind groove. A positioning locking block 9 is provided at one end of the backstop 1, and the other end of the backstop 1 abuts against the bottom of the blind groove. The outer periphery of the positioning locking block 9 is sleeved on the inner ring of the blind groove.

[0034] A pressure ring 10 and a rubber ring 111 are respectively provided on both sides of the disc slitting blade 3. The pressure ring 10 is fixedly connected to the slitting blade disc base 2 through the locking part 7. The outer diameter of the rubber ring 111 is smaller than the outer diameter of the disc slitting blade 3. The rubber ring 111 plays a buffering and supporting role when slitting the plate 400, so that the plate 400 can be smoothly and continuously slitted by the disc slitting force. The installation structure of the rubber ring 111 can be selected according to the practical situation. In this embodiment, the inner ring of the rubber ring 111 is sleeved on the slitting blade disc base 2.

[0035] like Figure 4 and Figure 5 As shown, the backstop 1 includes an outer ring 11, centering rollers 12, an elastic retainer 13, and clamping wedges 14. Multiple centering rollers 12 are arranged circumferentially inside the outer ring 11, and each centering roller 12 is rotatably connected to the outer periphery of the upper drive shaft 100 or the lower drive shaft 200. The outer ring 11 is sleeved onto the inner ring of the slitting disc seat 2. An elastic retainer 13 is provided between the outer ring 11 and the upper drive shaft 100 or the lower drive shaft 200. Multiple mounting slots are evenly distributed circumferentially on the elastic retainer 13, and a clamping wedge 14 is provided in each mounting slot. Block 14 can rotate within the mounting groove. The two ends of the clamping wedge block 14 can respectively abut against the inner circumference of the outer ring 11, the outer periphery of the upper drive shaft 100 or the lower drive shaft 200. In this embodiment, the clockwise rotation direction is the loosening direction of the backstop 1. The backstop 1 and the drive shaft can rotate continuously and can be moved axially by external force to adjust the axial position of the backstop 1. The counterclockwise direction is the locking direction of the backstop 1. The backstop 1 is firmly locked on the drive shaft by the outer ring 11 and the clamping wedge block 14 to achieve the purpose of continuous cutting of the plate.

[0036] The two sides of the clamping wedge 14 are pressed against the side wall of the mounting groove, so that one end of the clamping wedge 14 abuts against the outer periphery of the drive shaft. The clamping wedge 14 is installed in the outer ring 11 through the elastic retainer 13, and the elastic retainer 13 continuously presses the clamping wedge 14 firmly onto the drive shaft, so that the clamping wedge 14 can be pre-tightened on the outer periphery of the drive shaft and continuously clamp the drive shaft.

[0037] A stop post 16 is provided on each side of the clamping wedge 14. The stop post 16 can limit the relative position of the clamping wedge 14 and prevent the clamping wedge 14 from being clamped completely horizontally between the two centering rollers 12. It can effectively limit the extreme position of the clamping wedge 14. The end of the clamping wedge 14 near the outer periphery of the upper drive shaft 100 or the lower drive shaft 200 is provided with a follower arc 15. The follower arc 15 increases sequentially along the rotation direction of the upper drive shaft 100 or the lower drive shaft 200 so as to realize the one-way self-locking of the upper drive shaft 100 or the lower drive shaft 200 relative to the outer ring 11.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
