Description

Technical Field

[0001] This invention relates to the field of film recycling and reuse technology, and in particular to a film shredder. Background Technology

[0002] Currently, with the rapid development of the machinery industry, a large number of crushers are being produced and used. In industrial production, solid lumpy materials are fed into crushers for processing. The blades of existing crushers generate significant noise during cutting and crushing, directly affecting operators' ability to communicate and disrupting work. This noise also causes varying degrees of harm to the human body. To reduce the noise generated by crushers, an outer casing is typically added to the outside to weaken noise transmission; however, the sound insulation effect is not ideal. To further reduce noise generation, improvements and optimizations are urgently needed at the noise source (i.e., the cutting blades). Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a thin film shredder, which aims to optimize the structure of the shredding blades and set a soundproof box around the shredder to reduce the noise impact on the surrounding environment when the shredder is working.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A film shredder includes a shredder and a soundproof enclosure for the shredder. The shredder includes a base frame, a support mounted on the base frame, shredding blades mounted on the support, a drive device for driving the blades to achieve cutting, a feeding assembly mounted above the blades, and a screen assembly and a receiving assembly mounted below the blades. The shredding blades include a rotating shaft rotatably mounted on the support, multiple sets of moving blade assemblies mounted on the rotating shaft and arranged axially along the rotating shaft, and multiple sets of fixed blade assemblies fixed on the support and arranged circumferentially around the rotating shaft. The moving blade assemblies can cooperate with the fixed blade assemblies to achieve cutting. Under the axial projection of the rotating shaft, all the moving blade assemblies do not overlap.

[0005] Under the axial projection of the rotating shaft, a preset differential angle is formed between adjacent moving blade assemblies. Each set of moving blade assemblies includes a moving blade holder, multiple moving blades disposed on the moving blade holder, and a pressing blade plate disposed on the moving blades, which is used to press the moving blades against the pressing blade plate on the moving blade holder.

[0006] Each of the moving blade holders includes two symmetrically arranged wing plates. Each wing plate has the same number of support wing structures as the moving blades. Each support wing structure includes an outwardly extending support block and an adjusting block disposed next to the support block. Each moving blade is mounted on the support block on the two wing plates by pressing a blade plate and screws. The adjusting block is provided with a moving blade adjusting screw for adjusting the position of the moving blade.

[0007] The fixed blade assembly includes a pad, a fixed blade disposed on the pad, and a pressing plate for pressing the fixed blade onto the pad. The fixed blade extends axially along the rotating shaft, and the cutting edge of the fixed blade faces the axis of the rotating shaft.

[0008] The support includes two symmetrically arranged side plates and an arc plate disposed between the two side plates. The screen assembly is detachably disposed between the two side plates. The pad is fixed between the two side plates and spliced ​​with the arc plate. Each side plate is provided with a bearing seat. The two ends of the rotating shaft are rotatably connected to the corresponding bearing seat through bearings.

[0009] One end of the rotating shaft is fitted with a storage pulley, and the driving device includes a drive motor mounted on the base frame, a drive pulley mounted on the main shaft of the drive motor, and a driven pulley mounted on the other end of the rotating shaft. The drive pulley and the driven pulley are driven by a belt.

[0010] The base frame includes a base frame, legs set at the bottom of the base frame, at least two guide rods set on the base frame, and a slide plate slidably connected to the guide rods. The drive motor is set on the slide plate, and the slide plate is connected to the base frame through slide plate adjusting bolts and nuts.

[0011] The soundproof box includes a box frame and several soundproof panels installed on the outer perimeter of the box frame. Each of the top corners of the box frame is equipped with a hanging ring. The box frame is equipped with a bottom support. Each of the soundproof panels has a material inlet and a material outlet.

[0012] The receiving assembly includes a receiving hopper and a discharge pipe communicating with the bottom of the receiving hopper, and the receiving hopper is provided with a first handle; the feeding assembly includes a top shell and a feeding pipe vertically arranged on the top shell, and the top shell is connected to the support with screws; the screen assembly includes a support body and a screen arranged on the support body, the support body is provided with a second handle, and the support body is provided with two connecting ears, which are fixedly connected to the support by bolts.

[0013] The support is surrounded by a first housing, the drive device is surrounded by a second housing, and the storage wheel is surrounded by a third housing.

[0014] Beneficial effects: Compared with existing technologies, the film shredder provided by this invention, by setting multiple sets of identical but non-overlapping moving blade assemblies on the rotating shaft, and setting fixed blade assemblies around the moving blade assemblies, ensures that all moving blade assemblies do not simultaneously cooperate with the same fixed blade assembly to achieve cutting. That is, each fixed blade assembly cooperates with only one moving blade assembly at a time to cut and shred the film, thereby greatly reducing film shredding noise and effectively preventing large noise levels caused by multiple moving blade assemblies working simultaneously. Because a preset differential angle is formed between adjacent moving blade assemblies, after one moving blade assembly completes its cutting action, the adjacent moving blade assembly will immediately cooperate with the fixed blade assembly to complete the cutting, ensuring good continuity and ensuring that the film is fully shredded. In addition, when the shredder is working, most of the noise is blocked by the soundproof box, greatly reducing the outward transmission of noise and protecting the hearing health of workshop workers.

Detailed Implementation

[0029] This invention provides a thin film pulverizer. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the scope of protection of the invention.

[0030] Please see Figures 1-13This invention provides a film shredder, comprising a shredder 1 and a soundproof enclosure 2 for enclosing the shredder 1. The shredder 1 includes a base frame 11, a support 12 mounted on the base frame 11, shredding blades 3 mounted on the support 12, a drive device 4 for driving the blades to achieve cutting, a feeding assembly 5 mounted above the blades, and a screen 62 and a receiving assembly 7 mounted below the blades. The shredding blades 3 include a rotating shaft 31 rotatably mounted on the support 12, multiple sets of moving blade assemblies 32 mounted on the rotating shaft 31 and arranged axially along the rotating shaft 31, and multiple sets of fixed blade assemblies 33 fixed on the support 12 and arranged circumferentially around the rotating shaft 31. The moving blade assemblies 32 can cooperate with the fixed blade assemblies 33 to achieve cutting. Under the axial projection of the rotating shaft 31, all the moving blade assemblies 32 do not overlap with each other.

[0031] During operation, the film is fed into the crushing blades 3 through the feeding assembly 5. The drive device 4 drives the rotating shaft 31 to rotate. The moving blade assembly 32 on the rotating shaft 31 carries the film between the moving blade assembly 32 and the fixed blade assembly 33 during high-speed rotation, where it is cut. After being cut and crushed, the film becomes granular and flake-like, and then passes through the screen 62 and falls into the receiving assembly 7 before being discharged from the crusher 1. Since all the moving blade assemblies 32 have the same structure, by setting all the moving blade assemblies 32 to be non-overlapping under the axial projection of the rotating shaft 31, it can be ensured that all the moving blade assemblies 32 will not cooperate with the same fixed blade assembly 33 to cut at the same time. That is, a fixed blade assembly 33 only cooperates with one moving blade assembly 32 at a time to cut and crush the film, thereby greatly reducing the noise of film crushing and effectively preventing multiple moving blade assemblies 32 from working at the same time and generating a large amount of noise, thus reducing the amount of noise generated at the source. In addition, when the crusher 1 is working, most of the noise is blocked by the soundproof box 2, which greatly reduces the outward transmission of noise and protects the hearing health of the workshop staff.

[0032] Under the axial projection of the rotating shaft 31, a preset differential angle is formed between adjacent moving tool assemblies 32. Figure 3 (The angle indicated at point a) Since all moving blade assemblies 32 have the same structure, by setting all the moving blade assemblies 32 to be non-overlapping under the axial projection of the rotating shaft 31, it can be ensured that all moving blade assemblies 32 will not cooperate with the same fixed blade assembly 33 to achieve cutting at the same time. That is, a fixed blade assembly 33 only cooperates with one moving blade assembly 32 at a time to achieve film cutting and crushing, thereby greatly reducing film crushing noise and effectively preventing the large amount of noise caused by multiple moving blade assemblies 32 working at the same time. Since a preset differential angle is formed between adjacent moving blade assemblies 32, the differential angle can be understood as the circumferential offset of adjacent moving blade assemblies 32, and the differential angle is 6°~10°; after one moving blade assembly 32 completes the cutting action, the adjacent moving blade assembly 32 will immediately cooperate with the fixed blade assembly 33 to complete the cutting, with good continuity and ensuring that the film is fully crushed.

[0033] For details, please refer to Figure 2-7 Each set of moving blade assemblies 32 includes a moving blade holder 321, a plurality of moving blades 322 disposed on the moving blade holder 321, and a pressing blade plate 323 disposed on the moving blades for pressing the moving blades 322 against the pressing blade plate 323 on the moving blade holder 321. The gap between adjacent moving blade assemblies 32 is small, ensuring continuous pulverization of the film and improving the pulverization effect.

[0034] To reduce the overall weight of the moving tool holder 321 and facilitate manufacturing, each moving tool holder 321 employs two symmetrically arranged wing plates 3211. Each wing plate 3211 has the same number of support wing structures as the moving tools 322. Each support wing structure includes an outwardly extending support block 3212 and an adjusting block 3213 disposed beside the support block 3212. Each moving tool 322 is mounted on the support block 3212 on the two wing plates 3211 by pressing the moving tool plate 323 and screws. The adjusting block 3213 is provided with a moving tool adjusting screw (not shown in the figure) for adjusting the position of the moving tool. This can be understood as follows: the moving blade has elongated holes 3220 corresponding to the two support blocks 3212, extending along the length of the moving blade. The pressing blade plate 323 has the same number of first through holes 3230 as the elongated holes 3220. Each support block 3212 has the same number of first threaded holes as the elongated holes 3220, and each threaded hole corresponds to one of the elongated holes 3220. A first locking screw (not shown in the figure) is installed at each first through hole 3230, passing through the elongated hole 3220 and connecting to the first threaded hole. The adjusting block 3213 has an adjusting threaded hole 3214 facing the back of the moving blade. The adjusting screw (not shown in the figure) is screwed into the adjusting threaded hole 3214, and the threaded end of the adjusting screw presses against the moving blade. The elongated hole 3220 refers to a non-circular hole, specifically a rectangular hole, an oblong hole, a rounded rectangular hole, etc. When it is necessary to adjust the clearance between the moving blade and the fixed blade assembly 33, loosen the first locking screw, and turn the corresponding moving blade adjusting screw to gradually move the moving blade closer to the fixed blade to change the relative position of the moving blade and the positioning assembly. Then, relock the first locking screw. The adjustment is quite convenient.

[0035] For details, please refer to Figure 2-7The support 12 includes two symmetrically arranged side plates 121 and an arc plate 122 disposed between the two side plates 121. The screen assembly 6 is detachably disposed between the two side plates 121. Each side plate 121 is provided with a bearing seat 123. The two ends of the rotating shaft 31 are rotatably connected to the corresponding bearing seat 123 through bearings. Preferably, both ends of the rotating shaft 31 are provided with partition plates 311, and the moving blade assembly 32 is disposed between the two partition plates 311. By providing two partition plates 311, some noise can be blocked from propagating outward from the connection between the end of the rotating shaft 31 and the bearing, further reducing the noise caused during cutting and crushing.

[0036] For details, please refer to Figure 2-7 The fixed blade assembly 33 includes a pad 332, a fixed blade 333 disposed on the pad 332, and a pressing plate 334 for pressing the fixed blade 333 onto the pad 332. The fixed blade extends axially along the rotating shaft 31, with the cutting edge of the fixed blade 333 facing the axis of the rotating shaft 31. With this arrangement, one fixed blade 333 can cooperate with multiple moving blades to achieve cutting. All pads 332 are fixed between two side plates 121 and spliced ​​with an arc plate 122. The arc plate 122 can guide the film into the moving blade assembly 32 in accordance with its circumferential rotation trajectory, and prevent the material after cutting and crushing from spilling out.

[0037] To facilitate adjustment of the fixed blade position, the fixed blade 333 has multiple elongated holes 3330 extending along its width. The backing plate 332 has a number of second threaded holes (not visible in the figure) corresponding to the number of elongated holes 3330. The blade-pressing plate 334 has a number of second through holes 340 corresponding to the number of elongated holes 3330. A second locking screw (not shown in the figure) is installed at each second through hole 340 of the blade-pressing plate 334. The second locking screw passes through the elongated hole 3330 and is screwed into the second threaded hole. The elongated hole 3330 refers to a non-circular hole, which can be a rectangular hole, an oblong hole, a rounded rectangular hole, etc. When it is necessary to adjust the fixed blade position or align the two ends of the fixed blade, the corresponding second locking screw can be loosened to change the position of the fixed blade, and then the second locking screw can be re-locked, making the adjustment relatively convenient.

[0038] To ensure a reasonable distribution of moving blades on the moving blade assembly 32 and reduce cutting vibration, in this embodiment, the support structure is arranged in a circular array of four blades around the rotation axis 31. Adjacent moving blades on a single moving blade assembly 32 are perpendicular to each other and do not interfere with each other. Correspondingly, three sets of fixed blade assemblies 33 are provided, each fixed blade facing the rotation axis 31 and inclined relative to the horizontal plane, so that the moving blade 322 and the fixed blade 333 are also in an inclined state when they cooperate. This arrangement increases the cutting efficiency and improves the film cutting effect when the blade cuts the film.

[0039] For preferred options, please refer to [link / reference]. Figure 8 and Figure 9 One end of the rotating shaft 31 is fitted with a storage wheel 34. During operation, the storage wheel 34 uses inertia to reduce the load on the drive mechanism and also acts as a counterweight to increase the cutting force of the tool.

[0040] In fact, the drive device 4 includes a drive motor 41 mounted on the base frame 11, a drive pulley 42 sleeved on the main shaft of the drive motor, and a driven pulley 43 sleeved on the other end of the rotating shaft 31. The drive pulley 42 and the driven pulley 43 are connected by a belt (not shown in the figure). Under the transmission of the drive pulley 42 and the driven pulley 43, the drive motor 41 drives the moving blade assembly 32 and the fixed blade assembly 33 on the rotating shaft 31 to cooperate in crushing and cutting.

[0041] Specifically, please refer to 9. The base frame 11 includes a base frame 111, a seat 110 mounted on the base frame 111, support legs 112 mounted at the bottom of the base frame 111, at least two guide rods 113 mounted on the base frame 111, and a slide plate 114 slidably connected to the guide rods. The drive motor 41 is mounted on the slide plate 114. The slide plate 114 is connected to the base frame 111 by a slide plate adjusting bolt 115 and a nut. By turning the nut, the slide plate can be pushed to move, thereby causing the drive pulley 42 on the drive motor 41 to move away from the driven pulley 43, thereby tightening the belt and ensuring that the belt does not slip during transmission.

[0042] For further details, please refer to Figure 8 The receiving assembly 7 includes a receiving hopper 71 and a discharge pipe 72 communicating with the bottom of the receiving hopper 71. The receiving hopper 71 is provided with a first handle 73. In actual application, the top of the receiving hopper 71 is provided with a flange, which is mounted on the base frame 11. By pulling the first handle 73, impurities in the receiving hopper 71 and the discharge pipe 72 can be disassembled and cleaned. The feeding assembly 5 includes a top shell 51 and a feeding pipe 52 vertically arranged on the top shell 51. The top shell 51 is screwed to the bracket 12. The screen assembly 6 includes a support body 61 and a screen 62 arranged on the support body 61. The support body 61 is provided with a second handle 63. The support body 61 is provided with two connecting ears 64. The two connecting ears 64 are fixedly connected to the bracket 12 by bolts, thereby fixing the screen assembly 6. After the bolts are released, the screen assembly 6 can be pulled out from between the two side plates 121 by pulling the second handle 63, which is convenient for cleaning impurities on the screen 62.

[0043] For details, please refer to Figure 12 and Figure 13The soundproof box 2 includes a box frame 21 and several soundproof enclosure panels 22 installed on the periphery of the box frame 21. The soundproof enclosure panels 22 include a top panel, a front panel, a rear panel, a left panel, and a right panel. Each of the top corners of the box frame 21 is provided with a hanging ring 23, i.e., there are 4 hanging rings 23. The box frame 21 is provided with a base support 24, and the crusher 1 is installed on the base support 24. The crusher 1 is completely surrounded by the soundproof box 2, and most of the noise will be blocked by the soundproof box 2, greatly reducing the transmission of noise and protecting the hearing health of the workshop staff.

[0044] In practical applications, each soundproof enclosure 22 is provided with a feed opening 252 and a discharge opening 251. The free end of the feed pipe 52 is connected to a flexible feed pipe, which extends through the feed opening 252 and out of the soundproof box 2, facilitating the feeding of materials into the crusher 1. The free end of the discharge pipe 72 is connected to a flexible discharge pipe, which extends through the discharge opening 251 and out of the soundproof box 2. The crushed material is discharged from the soundproof box 2 through the flexible discharge pipe, facilitating collection and transportation.

[0045] During the manufacturing process of the crusher 1, the manufacturer will pre-assemble the finished crusher 1 into the soundproof box 2, so that the crusher 1 and the soundproof box 2 form a whole, which becomes a film crusher. The film crusher will be transported and shipped by a crane. The crane hook is connected to four lifting rings 23 by a circular four-hook rigging for lifting. By using this method to lift the soundproof box 2, the soundproof box 2 moves smoothly during the lifting process and will not tilt, which also reduces the risk of the soundproof box 2 falling during the lifting process.

[0046] In this embodiment, the enclosure frame 21 includes a square base frame 211 and a square top frame 212 positioned directly above the square base frame 211. The square base frame 211 is composed of four base frame strips 2111, which can be assembled by welding. The square top frame 212 is composed of four top frame strips 2121, which can also be assembled by welding. Each corner of the square base frame 211 is fixedly connected to the corresponding corner of the square top frame 212 by a vertical frame strip 213. The fixed connection can be achieved by welding. The base frame strips 2111, top frame strips 2121, and vertical frame strips 213 are all angle steel. Each angle steel consists of two mutually perpendicular steel strips. Each steel strip can serve as part of each outer surface of the soundproof enclosure 2, resulting in good structural strength and reliable use.

[0047] A reinforcing plate 214 is provided at the connection between adjacent top frame strips 2121, at the connection between top frame strips 2121 and vertical frame strips 213, and at the connection between bottom frame strips 2111 and vertical frame strips 213. The reinforcing plate 214 is triangular in shape. All reinforcing plates 214 are fixedly connected to the frame 21 of the enclosure by welding. The end face of the reinforcing plate 214 is attached to the end face of the angle steel strip. On the one hand, the reinforcing plate 214 serves as a reinforcement connection between adjacent frame strips, and on the other hand, it serves as the installation structure for the soundproof enclosure 22. Each reinforcing plate 214 is provided with an enclosure mounting hole 2141, which is a threaded hole. The soundproof enclosure 22 is connected to the threaded hole on the enclosure mounting hole 2141 by screws. After the soundproof enclosure 22 is installed, the outer side of the soundproof enclosure 22 will be flush with the outer side of the adjacent vertical frame strips 213, which is more aesthetically pleasing.

[0048] Preferably, the base 24 includes multiple parallel supporting square tubes 241 and a sound-insulating base plate 242 between adjacent supporting square tubes 241. Each supporting square tube 241 is provided with at least two connecting base blocks 243. All supporting square tubes 241 are fixedly connected to a square base frame 211. The angle steel on the square base frame 211 is folded inward to form a supporting plane. The supporting square tubes 241 press on the supporting plane. The number of support legs 112 of the crusher 1 is the same as the number of connecting base blocks 243, and they correspond one-to-one. The support legs 112 are fixed to the connecting base blocks 243 with screws, thereby connecting the crusher 1 and the soundproof box 2 to form a whole. By setting the sound-insulating base plate 242, the transmission of noise from the bottom of the soundproof box 2 can be reduced, ensuring the sound insulation effect.

[0049] Preferably, the bottom of the square base frame 211 is provided with a foot assembly 27. In this embodiment, each foot assembly 27 includes a mounting plate 271 and two feet 272. The mounting plate 271 is welded and fixed to the square base frame 211, and each foot 272 corresponds to one corner of the square base frame 211 and is threadedly connected to the mounting plate 271.

[0050] Preferably, a first housing 81 is provided around the support 12, a second housing 82 is provided around the drive device 4, and a third housing 83 is provided around the storage wheel 34. By providing the first housing 81, the second housing 82, and the third housing 83, the noise generated by the operation of the parts can be blocked to a certain extent, further reducing the amount of noise transmission. On the other hand, it can prevent the operator from accidentally touching the parts and causing injury during the operation of the crusher, thereby improving the safety of use.
