Description

Technical Field

[0001] This utility model relates to the field of crushing technology for various types of destruction media in destruction centers, specifically to a segmented integral blade crushing device. Background Technology

[0002] Currently, most media crushing products used in destruction centers on the market adopt the form of single blades. After the blades are inserted into the blade shaft in the direction of the blade helix, the blades are locked with a lock nut (with thread) to ensure that the blades do not move along the direction of the blade shaft. Finally, the lock nut stop block is locked to prevent the lock nut from rotating and loosening. When too many blades need to be installed, the cumulative error of the blades will increase, which may lead to friction between the blades and reduce the life of the blades. When the blade thickness is small, its strength will also be reduced. When the blade is damaged, the blades on the blade shaft will move and make the entire mechanism unusable. The spiral of the blades will also lead to excessive assembly time and cost due to the large number of blades. Furthermore, most products on the market use single-blade assemblies, which results in low blade strength and rapid wear; large cumulative errors during core assembly, and the inability to guarantee the gap between the main blade and the auxiliary blade, leading to inconsistent particle size; the industry's conventional method is to connect single-blade blades in series on the shaft, but due to cumulative errors in blade thickness processing, there may be mutual rubbing between blades on the rollers. If the gap is increased, it will affect the crushing effect and fail to meet the disposal standards. Because the blades are thinner, they may break when subjected to large forces or when crushing hard objects, rendering the entire crushing blade assembly unusable; some in the industry use integral blades, where the blade shaft and blade are one piece, which has extremely high processing costs and difficulty. If one blade is damaged, the entire blade shaft needs to be replaced, resulting in high maintenance costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a segmented integral blade crushing device, which solves the problems mentioned in the background technology, such as the entire blade assembly disintegrating and becoming unusable after a single blade is damaged during crushing, as well as the high difficulty in processing and maintenance, and the high cost.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a segmented integral blade crushing device, comprising a motor mounting plate, an upper side plate, a lower side plate, a blade shaft, a synchronous drive assembly, and segmented integral blades; Two motor mounting plates are provided; The upper side plate is provided as two, and the two upper side plates are detachably installed between the two motor mounting plates; The lower side plate is provided as two, and the two lower side plates are detachably disposed on the lower side of the two upper side plates respectively; The cutter shaft is provided as two, and both cutter shafts are rotatably mounted between the two upper side plates and the two lower side plates; The synchronous drive assembly is installed between the two cutter shafts; The segmented integral cutter is configured in multiple groups, and the multiple groups of segmented integral cutters are linearly and detachably connected to each cutter shaft.

[0005] Furthermore, the synchronization drive component includes: The motor is configured as two motors, and the two motors are respectively mounted on two motor mounting plates; Spacers are provided, and multiple spacers are respectively fixedly fitted onto two cutter shafts; A sprocket, wherein multiple sprockets are respectively mounted on the output ends of two motors and multiple spacers; The chain is provided in two parts, and the two chains are respectively driven and installed between a plurality of sprockets; The synchronous gears are configured in pairs, each mounted on one of the two cutter shafts, and the two synchronous gears mesh with each other.

Multiple screw holes are opened on the motor mounting plate, the first inner liner plate, the second inner liner plate, the upper side plate, the lower side plate, and the limiting blocks.

[0008] Furthermore, a lock nut is detachably installed on the cutter shaft, and a lock nut stop is installed on one side of the lock nut. A bearing sleeve is provided on the other side of the cutter shaft, and a bearing sleeve cover is installed on one side of the bearing sleeve.

[0011] Compared with the prior art, this utility model provides a segmented integral blade crushing device, which has the following beneficial effects: 1.

However, in this invention, multiple blades are integrated into one piece, and the bushing connected to the blade shaft at the root will not break. The equipment can continue to operate and meet the requirements for emergency disposal. If maintenance is required, only the corresponding segmented blade needs to be replaced. Compared with the existing technology, the maintenance cost is reduced. 2. In this utility model, the segmented integral blade reduces the cumulative error during blade assembly, ensuring uniform gaps between each blade and resulting in better material shearing. 3. In this utility model, the segmented integral blade is made of high-strength and high-toughness cold work abrasive steel, which gives the blade the advantages of high strength, high toughness and high wear resistance, and solves the pain points of blade brittleness, wear and deformation in the prior art; 4. In this utility model, the thickness of a single blade can be processed according to the requirements of secondary crushing and destruction of particles of different media; 5.

The blades adopt multi-blade integrated blades, which effectively reduces the difficulty of processing and maintenance, improves the life of the crushing device and improves the crushing effect (particle consistency), thus facilitating the crushing of media that need to be crushed in the destruction center, ensuring that the particles meet the confidentiality requirements, and can meet the requirements of emergency destruction.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 5 A segmented integral blade crushing device includes a motor mounting plate 1, an upper side plate 2, a lower side plate 3, a blade shaft 4, a synchronous drive assembly, and segmented integral blades 5. There are two motor mounting plates 1 and two upper side plates 2, which are detachably installed between the two motor mounting plates 1. There are two lower side plates 3, which are detachably installed on the lower side of the two upper side plates 2. There are two blade shafts 4, which are rotatably installed between the two upper side plates 2 and the two lower side plates 3. The synchronous drive assembly is installed between the two blade shafts 4. There are multiple sets of segmented integral blades 5, which are linearly and detachably connected to each blade shaft 4.

[0016] refer to Figure 1 as well as Figure 2 The synchronous drive assembly includes a motor 6, a spacer 7, a sprocket 8, a chain 9, and a synchronous gear 10. There are two motors 6, which are respectively mounted on two motor mounting plates 1. The starting time and speed of the two motors 6 are set to be the same. There are multiple spacers 7, which are respectively fixedly mounted on two cutter shafts 4. There are multiple sprockets 8, which are respectively mounted on the output end of the two motors 6 and multiple spacers 7. There are two chains 9, which are respectively driven between multiple sprockets 8. There are two synchronous gears 10, which are respectively mounted on two cutter shafts 4 and mesh with each other. Guide brackets 23 are fixedly connected to the side of the two motor mounting plates 1 that are close to each other. An encoder 15 is installed on one of the upper side plates 2 to check whether the equipment is stalled. End covers 24 are installed on both sides of the two cutter shafts 4, and two gear baffles 25 are symmetrically installed on both sides of the two synchronous gears 10. When two motors 6 are started simultaneously, multiple sprockets 8 and two chains 9 drive the two cutter shafts 4 to rotate simultaneously. This allows the multi-component segmented cutter 5 on the two cutter shafts 4 to rotate simultaneously, thereby uniformly crushing the medium. The motor 6 provides the power source for the equipment and drives the crushing blades to rotate through the sprocket 8 and chain 9 to cut the material. The spacer 7 and end cover 24 prevent the sprocket 8, sprocket 8 and synchronous gear 10 from moving in the direction of the blade shaft 4. The guide bracket 23 guides the material and prevents the blades from not biting the crushing medium. The synchronous gear 10 ensures the synchronization of the two blade shafts 4 and prevents one blade shaft 4 from moving faster than the other, which would cause the crushed medium to be unable to be bitten. The gear baffle 25 effectively prevents impurities from entering the synchronous gear 10 and damaging the gear.

[0017] refer to Figure 2 as well as Figure 3 Each upper side plate 2 and each lower side plate 3 is detachably connected to an inner lining plate 11 and an inner lining plate 2 12, and multiple grate rods 13 are connected between multiple inner lining plates 11 and multiple inner lining plates 2 12. Two grate plates 14 are installed between multiple grate rods 13. Multiple limiting blocks 16 are detachably connected between two upper side plates 2 and two lower side plates 3. Multiple screw holes are opened on the motor 6 mounting plate 1, inner lining plate 11, inner lining plate 2 12, upper side plate 2, lower side plate 3 and limiting blocks 16. The upper side plate 2 and the lower side plate 3 are fixed to the cutter shaft 4 by multiple screw holes and screws. The grate rod 13 fixes the grate plate 14. The grate plate 14 can remove the crushing medium to prevent the material from sticking to the blade and form a closed space with the cutter shaft 4 to prevent the material from running out from the side of the cutter shaft 4. The inner liner plate 11 can prevent the material from running out from the tail blade without being crushed. Furthermore, the two upper side plates 2 and the two lower side plates 3 form a split side plate. The upper side plates 2 and the lower side plates 3 are double-fastened by the inner lining plate, screw holes and high-strength bolts on the top. This can reduce the difficulty of maintenance while ensuring the structural strength. When replacing the segmented integral cutter, it is only necessary to remove the upper side plate 2 and the inner lining plate 11 to take out the cutter shaft 4 to replace the blade, without disassembling the machine core.

[0018] refer to Figure 4 as well as Figure 5 A lock nut 17 is detachably installed on the cutter shaft 4, and a lock nut stop 18 is installed on one side of the lock nut 17. Through the cooperation of the lock nut 17 and the lock nut stop 18, the installation of the multi-section integral cutter 5 on the cutter shaft 4 can be limited, which improves the stability of the installation of the multi-section integral cutter 5 on the cutter shaft 4. A bearing sleeve 19 is provided on the other side of the cutter shaft 4, and a bearing sleeve cover 20 is installed on one side of the bearing sleeve 19. Bearing 1 21 and bearing 22 are installed between the bearing sleeve 19 and the bearing sleeve cover 20. After installing bearing 1 21 and bearing 2 22 onto the cutter shaft 4, the bearings are sealed with bearing sleeve 19 and bearing sleeve cover 20 to prevent material from entering the bearings and causing jamming or the cutter shaft 4 from getting stuck and not rotating.

[0019] In summary, this segmented integral blade shredder is an industrial-grade shredder used to destroy confidential paper media. It utilizes roller shredder blades to shred the paper media into fine particles, achieving the purpose of information destruction. The blades are multi-blade integrated blades. When the blades wear down or the blade head breaks, the blade body of this segmented integral blade shredder does not disintegrate, thus not affecting continued use. When the blades are severely broken, only the problematic blade assembly needs to be replaced, without replacing the entire segmented integral blade assembly. This significantly reduces maintenance costs and improves the lifespan of the shredder and the shredding effect (particle consistency) while effectively reducing processing and maintenance difficulty.
