[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a slitting device with a stable structure is provided to solve the problem that the slitting blades are prone to wobble and breakage when cutting inorganic fiber materials such as rock wool and glass wool, which affects the cutting accuracy.

[0006] To achieve the above objectives, a slitting device with a stable structure is provided, comprising:

[0007] A base, on which two opposing support frames are vertically mounted, and a rotating shaft is rotatably mounted between the two support frames. A driving component for driving the rotating shaft is mounted on the support frame.

[0008] The slitting blades are detachably mounted on the rotating shaft, and the multiple slitting blades are spaced apart along the axial direction of the rotating shaft.

[0009] A stabilizer is disposed between two adjacent slitting blades and is mounted between the two support frames. Rollers are rotatably mounted on opposite sides of the stabilizer. A limiting space is formed between the rollers of the stabilizer on opposite sides of the slitting blade. When the slitting blade wobbles, the rollers support the slitting blade to stabilize it.

[0010] Furthermore, the stabilizer includes two arms arranged at an angle, one end of which is connected together, and the other end of each arm is rotatably mounted with a roller.

[0011] Furthermore, the roller's axle is arranged along the radial direction of the slitting blade.

[0012] Furthermore, multiple tube sections are movably sleeved on the rotating shaft, and a fitting hole is formed in the middle of the slitting blade. The slitting blade is movably sleeved on the rotating shaft and disposed between two adjacent tube sections. A keyway is formed on the side of the rotating shaft along the axial direction of the rotating shaft. A transmission key is detachably embedded in the keyway. The inner wall of the tube section and the wall of the fitting hole are respectively formed with limiting through grooves. One side of the transmission key is movably embedded in the limiting through grooves of the tube section and the slitting blade. Both ends of the rotating shaft are respectively detachably sleeved with bushings for converging the multiple tube sections to lock the slitting blade between two adjacent tube sections.

[0013] Furthermore, a baffle is connected between the two support frames, and the stabilizer is mounted on the baffle.

[0014] Furthermore, there are two rotating shafts, which are arranged in the same direction. One rotating shaft is located diagonally above the other rotating shaft, and a feeding space is formed between the two rotating shafts. The cutting blades on the two rotating shafts are staggered.

[0015] Furthermore, the driving component is a drive motor, which is connected to the other rotating shaft via a synchronous belt.

[0016] Furthermore, there are two baffles, which are respectively disposed on opposite sides of the rotating shaft, and the two baffles have feeding ports aligned with the feeding space.

[0017] Furthermore, a supporting base plate is connected between the bottom walls of the feed inlets of the two baffles, and a limiting top plate is connected between the top walls of the feed inlets of the two baffles. The supporting base plate has a plurality of first strip-shaped perforations, each corresponding to a plurality of cutting blades on the other rotating shaft. The upper part of the cutting blades on the other rotating shaft is rotatably inserted through the first strip-shaped perforations and extends above the supporting base plate. The limiting top plate has a plurality of second strip-shaped perforations, each corresponding to a plurality of cutting blades on one rotating shaft. The lower part of the cutting blades on one rotating shaft is rotatably inserted through the second strip-shaped perforations and extends below the limiting top plate.

[0018] Furthermore, two supports are installed on the outer side of a baffle on the rear side of the rotating shaft. A milling cutter is rotatably mounted on each of the two supports. The milling cutters on the two supports are respectively aligned with the cutting blades at both ends of the rotating shaft. A trimming motor is installed on the support and is drivenly connected to the milling cutter.

[0019] The beneficial effect of this utility model is that the slitting device with a stable structure of this utility model improves the stability and service life of the slitting blades and improves the cutting accuracy of materials by installing a stabilizer between adjacent slitting blades and the roller of the stabilizer supporting the slitting blades when the slitting blades sway.

[0020] The present invention provides a slitting device with a stable structure. By using a bushing to gather multiple pipe sections on the rotating shaft, the slitting blades are locked between adjacent pipe sections. The installation and removal of the slitting blades are quick and convenient, facilitating the rapid replacement of single or multiple slitting blades and reducing the maintenance cost of the slitting blades.

[0021] The present invention provides a slitting device with a stable structure. By setting two rotating shafts, the material is cut by double rows of slitting blades on the two rotating shafts. Compared with slitting devices with a single rotating shaft and a single row of slitting blades, the slitting blades are relatively smaller, saving materials, having strong stability, and low replacement costs.

[0034] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Reference Figures 1 to 11 As shown, this utility model provides a slitting device with a stable structure, including: a base 1, a rotating shaft 2, a slitting blade 3, and a stabilizer 4.

[0037] In this embodiment, the base 1 is rectangular, and two support frames 11 are vertically mounted on the base 1, with the two support frames 11 arranged opposite each other. Preferably, the two support frames 11 are respectively located at opposite ends of the base 1. A rotating shaft 2 is rotatably mounted between the two support frames 11. A driving component for driving the rotating shaft 2 is mounted on the support frame 11. In this embodiment, the driving component is a drive motor 5, and the drive motor 5 is connected to the rotating shaft 2.

[0038] Multiple slitting blades 3 are detachably mounted on the rotating shaft 2, and the multiple slitting blades 3 are spaced apart along the axial direction of the rotating shaft 2.

[0039] For details, please refer to Figures 3-5 As shown, multiple tube sections 21 are movably sleeved on the rotating shaft 2, and the multiple tube sections 21 are coaxially arranged with the rotating shaft 2. A fitting hole a is formed in the middle of the slitting blade 3, and the slitting blade 3 is movably sleeved on the rotating shaft 2 and arranged between two adjacent tube sections 21.

[0040] A keyway b is provided on the side of the rotating shaft 2, and the keyway b is arranged along the axial direction of the rotating shaft 2. A transmission key 22 is detachably embedded in the keyway b. The inner wall of the tube section 21 and the wall of the mounting hole a are respectively formed with limiting grooves c, and the limiting grooves c are arranged along the axial direction of the rotating shaft 2. One side of the transmission key 22 is movably embedded in the limiting grooves c of the tube section 21 and the slitting blade 3.

[0041] The two ends of the rotating shaft 2 are respectively detachably fitted with bushings 23, and the two bushings 23 bind together multiple tube sections 21, thereby locking the slitting blade 3 between two adjacent tube sections 21.

[0042] In this embodiment, the inner wall of the bushing 23 is provided with an assembly slot, and the transmission key 22 is embedded in the assembly slot of the bushing 23. The side of the bushing 23 is provided with a through hole, and the rotating shaft 2 is provided with a threaded locking hole. By passing the threaded locking rod (not shown in the figure) through the through hole of the bushing 23 and screwing it into the threaded locking hole, the bushing 23 is locked to the rotating shaft 2, thereby realizing the quick installation of the slitting blade 3.

[0043] Combination Figure 1 , Figure 2 As shown, the slitting device of this utility model with a stable structure includes multiple stabilizers 4. Stabilizers 4 are respectively disposed between adjacent slitting blades 3. The stabilizers 4 are mounted between two support frames 11. In this embodiment, a baffle 12 is connected between the two support frames 11, and the stabilizers 4 are mounted on the baffle 12.

[0044] Combination Figure 2 , Figure 6 As shown, rollers 42 are rotatably mounted on opposite sides of the stabilizer 4. A limiting space is formed between the rollers 42 of the stabilizer 4 on opposite sides of the slitting blade 3 (i.e., a gap is formed between the rollers 42 and the slitting blade 3).

[0045] Specifically, in this embodiment, the stabilizer 4 includes two arms 41 arranged at an angle. One end of the two arms 41 is connected together, and the other end of each arm 41 is rotatably mounted with a roller 42.

[0046] Preferably, the axle of the roller 42 is arranged along the radial direction of the slitting blade 3.

[0047] Under normal conditions, the slitting blade 3 and the roller 42 of the stabilizer 4 do not interfere with each other. When the slitting blade 3 wobbles while cutting inorganic fiber materials such as rock wool and glass wool, the roller 42 of the stabilizer 4 supports the slitting blade 3 and rotates with the slitting blade 3, thereby stabilizing the slitting blade 3, reducing the wobbling amplitude of the slitting blade 3, improving the slitting accuracy, and reducing the risk of breakage of the slitting blade 3.

[0048] In this embodiment, the roller 42 is made of ceramic or nylon material, which combines wear resistance and durability. Dustproof rings 43 are provided on both sides of the roller 42.

[0049] The present invention provides a slitting device with a stable structure. The slitting blade 3 is a non-serrated blade, which generates less dust during the slitting process compared to a serrated blade, making it more environmentally friendly and reducing blade cost.

[0050] See Figures 7-9As shown, in a preferred embodiment, there are two rotating shafts 2, which are arranged in the same direction. One rotating shaft 2 is located diagonally above the other rotating shaft 2, and a feeding space d is formed between the two rotating shafts 2. The cutting blades 3 on the two rotating shafts 2 are staggered vertically.

[0051] The drive motor 5 is connected to another rotating shaft 2, which is connected to the first rotating shaft 2 via a synchronous belt. After the drive motor 5 starts, it drives the two rotating shafts 2 to rotate synchronously.

[0052] There are two baffles 12, which are respectively set on opposite sides of the rotating shaft 2 (opposite sides of the base 1). Each baffle 12 has a feeding port e, which is aligned with the feeding space d.

[0053] A supporting base plate 81 is connected between the bottom walls of the feed inlets e of the two baffles 12. The supporting base plate 81 has a plurality of first strip-shaped perforations, which correspond one-to-one with a plurality of slitting blades 3 on another rotating shaft 2. The upper part of the slitting blades 3 on the other rotating shaft 2 is rotatably inserted through the first strip-shaped perforations and extends above the supporting base plate 81.

[0054] A limiting top plate 82 is connected between the top walls of the feed inlets e of the two baffles 12. The limiting top plate 82 has a plurality of second strip-shaped perforations, each corresponding to a plurality of slitting blades 3 on a rotating shaft 2. The lower part of the slitting blades 3 on the rotating shaft 2 is rotatably inserted through the second strip-shaped perforations and extends below the limiting top plate 82.

[0055] By installing the supporting base plate 81 and the limiting top plate 82, the stability of the material pushing process and the cutting process can be improved, thereby enhancing the cutting effect.

[0056] By setting two rotating shafts 2, the double-row slitting blades 3 on the two rotating shafts 2 can cut the upper and lower parts of the material respectively. When cutting materials of the same height, the double-row slitting blades are smaller, use less material, and have lower replacement costs compared to the single-row slitting blades. At the same time, the slitting blades have a smaller wobble amplitude and greater stability.

[0057] See Figure 9 As shown, in a preferred embodiment, two supports 121 are mounted on the outer side of a baffle 12 on the rear side of the rotating shaft 2 (rear side of the base 1), and milling cutters 6 are rotatably mounted on each of the two supports 121. The milling cutters 6 on the two supports 121 are respectively aligned with the cutting blades 3 at both ends of the rotating shaft 2. A trimming motor 7 is mounted on the support 121, and the trimming motor 7 is drivenly connected to the milling cutters 6.

[0058] During the slitting process of inorganic fiber materials such as rock wool and glass wool, the slitting blades at both ends of the rotating shaft 2 are squeezed outwards by the material in the middle and the slitting blades. Compared with the material strips cut in the middle, the material strips cut on both sides are prone to being larger in size. By installing two milling cutters 6, the size of the material strips cut on both sides can be corrected, so that the size of the material strips cut on both sides is consistent with the size of the material strip cut in the middle.

[0059] See Figure 10 As shown, in a preferred embodiment, guide plates 13 are elastically mounted on opposite sides of the two support frames 11.

[0060] See Figure 11 As shown, in a preferred embodiment, collection boxes 14 are respectively installed on opposite sides of the two support frames 11.

[0061] The present invention provides a slitting device with a stable structure. The inorganic fiber materials such as rock wool and glass wool to be slitted are pushed to the slitting device by the feeding mechanism (the feeding mechanism is existing technology and will not be described in detail in this embodiment) on the slitting production line for slitting operation. During the pushing process, two guide plates 13 limit and guide the material.

[0062] During the slitting process, when the slitting blade 3 wobbles, the roller 42 of the stabilizer 4 supports the slitting blade 3, reducing the wobble amplitude of the slitting blade 3, maintaining the stability of the slitting blade, improving cutting accuracy, and reducing the risk of the slitting blade breaking.

[0063] Waste generated during the material cutting process falls into collection box 14 for centralized recycling and processing.

[0064] After the cutting is completed, the trimming motor 7 drives the milling cutter 6 to correct the material strips on both sides, so that the size of the material strips on both sides is consistent with the size of the material strip in the middle, reducing dimensional errors.

[0065] The slitting device of this invention, with its stable structure, enables rapid installation of the slitting blades 3 by using a bushing 23 to gather multiple tube sections 21 on the rotating shaft. This facilitates quick replacement of single or multiple slitting blades, reducing maintenance costs.

[0066] This utility model discloses a slitting device with a stable structure. It utilizes two rows of slitting blades on two rotating shafts to cut the upper and lower parts of the material separately. Compared to slitting devices with a single rotating shaft and a single row of blades, this device features smaller blades, uses less material, and has lower replacement costs. Furthermore, the blades exhibit less sway, greater stability, and a longer service life.

[0067] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
