Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and specifically discloses a semi-automatic crushing device that facilitates the replacement of cutting tools. Background Technology

[0002] In the production, distribution, and management of tobacco products, barcodes or QR codes on cigarette packaging serve as crucial information carriers, enabling product traceability, anti-counterfeiting verification, and logistics tracking. However, with increasing awareness of information security and increasingly stringent industry regulations, untreated identifiable markings on discarded cigarette packaging may pose a risk of information leakage and could even be exploited by criminals for the manufacture or illegal distribution of counterfeit products. Therefore, the safe and efficient shredding of cigarette packaging containing barcodes / QR codes has become a pressing technical challenge for the tobacco industry.

[0003] Based on the above, in the prior art, patent CN202121849879.9 discloses an intelligent processing system for cigarette box barcode labels, including a conveying platform. A destruction box is fixedly connected to the top left end of the conveying platform, and a fixing plate is fixedly connected to the right end of the front surface of the destruction box. An electronic computer is fixedly installed on the top of the fixing plate, and a PLC controller is fixedly installed at the bottom of the fixing plate. An industrial camera is fixedly installed on the top left end of the inner cavity of the destruction box, and an industrial robot is fixedly installed in the middle of the top of the inner cavity of the destruction box. This utility model, through the coordinated action of the industrial camera, conveying platform, destruction box, electronic computer, PLC controller, industrial robot, laser machine, blower, air inlet plate, filter box, activated carbon filter, crushing motor, crushing box and crushing shaft, and arc-shaped sieve plate, achieves the effect of automatic destruction of cigarette box labels. The destruction effect is excellent, effectively avoiding information leakage caused by incomplete destruction.

[0004] Although existing intelligent processing systems for cigarette box barcode labels have achieved automatic destruction of cigarette box labels to a certain extent, the system still has some shortcomings. Specifically, when the blades need to be replaced due to wear, or when different specifications of blades need to be replaced according to the size and density of barcodes / QR codes on different cigarette packaging papers, it is often necessary to disassemble the outer shell of the shredder, loosen multiple sets of fixing connectors, and even require the assistance of professional tools to remove the blade components. The operation steps are cumbersome and time-consuming. This complicated replacement method not only increases the downtime of equipment maintenance and reduces processing efficiency, but also makes it easy to cause bumps to other parts during disassembly and assembly, affecting the overall stability of the equipment. Utility Model Content

[0005] To address the technical deficiencies in the background technology, this utility model proposes a semi-automatic code-breaking device that facilitates tool replacement, solving the aforementioned technical problems and meeting practical needs. The specific technical solution is as follows:

[0006] A semi-automatic crushing device with easy-to-change blades includes a housing, a feed hopper connected to the top of the housing, and a crushing box located in the middle of the housing. Inside the housing, below the crushing box, is a removable collection frame. Inside the crushing box is a removable sliding assembly. A crushing component is mounted on the surface of the sliding assembly, and a sliding plate is provided on the surface of the sliding assembly. A mounting plate is symmetrically positioned on the surface of the sliding plate. The crushing component is mounted on the sliding plate via the mounting plate. Sliding strips are provided on the long sides of the bottom surface of the sliding plate. The inner bottom surface of the crushing box has symmetrically arranged sliding grooves that can slide with the sliding plate. Pull-out openings and fixing openings for accommodating the mounting plates are provided on the two side surfaces of the crushing box. The crushing assembly includes two sets of crushing blades rotatably connected to the mounting plates at both ends and arranged parallel to each other. Each set of crushing blades includes a rotating shaft rotatably connected to the mounting plates at both ends and a plurality of crushing blades equidistantly arranged along the axial direction of the rotating shaft. The crushing blades in the two sets of crushing blades are staggered.

[0007] As a further technical solution of this utility model, the bottom surface of the crushing box is provided with a first discharge port, and the surface of the sliding plate is provided with a second discharge port that corresponds to and is connected to the first discharge port.

[0008] As a further technical solution of this utility model, the crushing assembly also includes drive gears that are respectively disposed at one end of the rotating shaft of the two sets of crushing blades and mesh with each other, a coupling connected to the rotating shaft of one of the sets of crushing blades, and a drive motor connected to the coupling and mounted on the upper surface of the slide plate. The slide plate is provided with a pull-out plate at the end of the side where the drive motor is mounted.

[0009] As a further technical solution of this utility model, the mounting plate includes an upper mounting plate and a lower mounting plate that cooperate with each other. The surface of the lower mounting plate is symmetrically provided with an arc-bottom mounting groove, and a fixed plate that can slide up and down in the arc-bottom mounting groove is correspondingly provided inside the arc-bottom mounting groove.

[0010] As a further technical solution of this utility model, the lower end of the fixed plate is provided with an arc-shaped groove with the arc bottom mounting groove bent in the opposite direction, and the rotating shaft can rotate freely within the through groove formed by the arc bottom mounting groove and the arc-shaped groove.

[0011] As a further technical solution of this utility model, hexagonal socket head cap screws are symmetrically arranged at both ends of the upper mounting plate, and the hexagonal socket head cap screws pass through the upper mounting plate and are threadedly connected to the lower mounting plate.

[0012] As a further technical solution of this utility model, fixing strips connected to the outer surface of the crushing box are symmetrically arranged in the longitudinal gaps between the mounting plate and the pull-out port and the fixing port, and threaded fixing bolts are arranged through the fixing strips.

[0013] The beneficial effects of this utility model are as follows:

[0014] The entire shredding assembly can be pulled out and slidable through the cooperation of the sliding plate, slide bar, and slide groove of the sliding component. Users can remove the shredding assembly from the housing without disassembling the outer shell or using complicated tools, which facilitates the replacement of the shredding blades. The shredding assembly is quickly assembled with the sliding plate through the cooperation of the upper and lower mounting plates. The internal hexagonal screw design facilitates disassembly.

Detailed Implementation

[0021] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0022] Combination Figures 1 to 5 As shown, a semi-automatic crushing device with easy-to-change blades includes a housing 1, a feed hopper 2 connected to the top of the housing 1, and a crushing box 3 located in the middle of the housing 1. Inside the housing 1, below the crushing box 3, is a removable collection frame 4. Inside the crushing box 3, is a removable sliding assembly 6. A crushing assembly 5 is mounted on the surface of the sliding assembly 6. A sliding plate 61 is provided on the surface of the sliding assembly 6. Symmetrically positioned on the surface of the sliding plate 61 are mounting plates 64. The crushing assembly 5 is mounted on the sliding plate 61 via the mounting plates 64. The bottom surface of the sliding plate 61 has two long sides... Each side is provided with a sliding strip 62. The inner bottom surface of the crushing box 3 is symmetrically provided with a sliding groove 34 that can slide in cooperation with the sliding plate 61. The two ends of the crushing box 3 are respectively provided with a pull-out opening 32 and a fixing opening 33 that can accommodate the mounting plate 64. The crushing assembly 5 includes two sets of crushing blade groups 56 that are rotatably connected to the mounting plate 64 at both ends and arranged in parallel. Each crushing blade group 56 includes a rotating shaft 51 that is rotatably connected to the mounting plate 64 at both ends and a plurality of crushing blades 52 that are equidistantly arranged along the axial direction of the rotating shaft 51. The crushing blades 52 between the two sets of crushing blade groups 56 are staggered.

[0023] Furthermore, in the above structure, the bottom surface of the crushing box 3 is provided with a first discharge port 31, and the surface of the sliding plate 61 is provided with a second discharge port 65 that corresponds to and communicates with the first discharge port 31.

[0024] The crushing component 5 of this utility model adopts two sets of parallel crushing blade groups 56. Each set of crushing blade groups 56 includes a rotating shaft 51 and crushing blades 52 arranged equidistantly along the axial direction. The two sets of blades are arranged in a staggered manner. When the drive motor 55 drives the rotating shaft 51 to rotate through the coupling 54, the two sets of blades rotate in opposite directions, forming a shearing force to repeatedly cut and tear the barcode / QR code entering the crushing area. The rotating shaft 51 can rotate freely through the through groove surrounded by the arc-bottom mounting groove 646 and the arc-surface groove 643, ensuring high stability of the blades when running at high speed and avoiding deviation that affects the crushing effect.

[0025] The entire assembly of the crushing component 5 can be pulled out and slid through the sliding plate 61, the sliding strip 62, and the sliding groove 34. The user can remove the crushing component 5 from the housing 1 through the sliding component 6, shortening the replacement time of the crushing blade assembly 56. The crushing component 5 is connected to the upper mounting plate 641 and the lower mounting plate 645, and combined with the internal hexagonal fixing screws 644, fixing strips 7, and fixing bolts 71 to achieve quick assembly and stable fixation, reducing the maintenance threshold. The staggered crushing blades 52 cut the lines, patterns, and coding information of the barcode / QR code into tiny particles through the closely coordinated shearing action, completely destroying its macroscopic and microscopic structure, making it impossible to scan or recognize.

[0026] Users can move the shredding assembly 5 out of the housing 1 by sliding component 6, which facilitates the replacement of the shredding blade assembly 56. Users can replace the shredding blade assembly 56 with different specifications according to the paper material (such as thickness and toughness) and the shredding requirements (such as particle size) to ensure the thorough shredding of various barcodes / QR codes.

[0027] After the cigarette packaging paper enters the crushing box 3 from the feed hopper 2, it is completely wrapped and crushed by two sets of blades. The crushed material falls directly into the collection box 4 below through the second discharge port 65 of the slide plate 61 and the first discharge port 31 of the crushing box 3. The whole process is closed to prevent the crushed material from leaking out and causing information residue.

[0028] As a preferred embodiment of the present invention, the crushing assembly 5 further includes drive gears 53 respectively disposed at one end of the rotating shaft 51 of the two sets of crushing blades 56 and meshing with each other, a coupling 54 connected to the rotating shaft 51 of one set of crushing blades 56, and a drive motor 55 connected to the coupling 54 and mounted on the upper surface of the slide plate 61. The slide plate 61 is provided with a pull-out plate 63 at the end of the side where the drive motor 55 is mounted.

[0029] The drive motor 55 is directly connected to the rotating shaft 51 of one of the crushing blade groups 56 via a coupling 54, driving the rotating shaft 51 to rotate. The ends of the rotating shafts 51 of the two crushing blade groups 56 are respectively provided with mutually meshing drive gears 53. When one rotating shaft 51 is driven, it drives the other rotating shaft 51 to rotate through gear meshing, forming a shearing force of the double blade groups rotating in opposite directions.

[0030] Two sets of parallel and staggered shredders 56 rotate via a drive gear 53, creating a dual effect of shearing and tearing on the barcodes / QR codes entering the shredding area, ensuring that the paper is thoroughly shredded into tiny particles and avoiding the retention of identifiable information.

[0031] As one of the preferred embodiments of this utility model, the mounting plate 64 includes an upper mounting plate 641 and a lower mounting plate 645 that cooperate with each other. The surface of the lower mounting plate 645 is symmetrically arranged in the arc-bottom mounting groove 646, and a fixing plate 642 that can slide up and down in the arc-bottom mounting groove 646 is correspondingly arranged inside the arc-bottom mounting groove 646.

[0032] Furthermore, in the above structure, the lower end of the fixed plate 642 is provided with an arc-bottom mounting groove 646 and an arc-shaped groove 643 that is bent in the opposite direction, and the rotating shaft 51 can rotate freely within the through groove formed by the arc-bottom mounting groove 646 and the arc-shaped groove 643.

[0033] Furthermore, in the above structure, the upper mounting plate 641 is symmetrically provided with hexagonal socket head cap screws 644 at both ends, and the hexagonal socket head cap screws 644 pass through the upper mounting plate 641 and are threadedly connected to the lower mounting plate 645.

[0034] The mounting plate 64 consists of an upper mounting plate 641 and a lower mounting plate 645. The upper mounting plate 641 and the lower mounting plate 645 are connected by internal hexagonal head screws 644 to form an integral frame. The lower mounting plate 645 has symmetrically arranged arc-bottomed mounting grooves 646 on its surface to provide a sliding track for fixing the mounting plate 642. The upper mounting plate 641 is fixed to the lower mounting plate 645 by screws to ensure the stability of the overall structure.

[0035] The fixing plate 642 installed in the arc-bottom mounting groove 646 can slide up and down. Its lower end is provided with an arc-shaped groove 643 that bends in the opposite direction to the arc-bottom mounting groove 646. When the fixing plate 642 slides in the groove, the arc-shaped groove 643 and the arc-bottom mounting groove 646 together form a through groove, providing space for the rotating shaft 51 to rotate freely. The two ends of the rotating shaft 51 are embedded in the through groove enclosed by the arc-bottom mounting groove 646 and the arc-shaped groove 643. The geometry of the through groove restricts the radial movement of the rotating shaft 51, while allowing it to rotate freely around the axis.

[0036] It should be noted that, in order to make the rotation of the rotating shaft 51 smoother within the through groove formed by the arc-bottom mounting groove 646 and the arc-surface groove 643, a bearing (not shown) can be installed on the rotating shaft 51. The inner ring of the bearing is fitted onto the rotating shaft 51, and the outer ring is fixed in the through groove. For this purpose, a semi-circular bearing mounting groove should be provided in the arc-bottom mounting groove 646, and a matching semi-circular bearing mounting groove should also be provided in the arc-surface groove 643 of the fixing plate 642. When the fixing plate 642 slides into place, the two form a complete circular bearing seat to fix the outer ring of the bearing. To ensure the stability of the bearing installation, the size of the bearing mounting groove should match the outer ring of the bearing.

[0037] The upper mounting plate 641 and the lower mounting plate 645 are connected by hex socket head cap screws 644. Users can quickly disassemble or assemble the mounting plate 64 without complicated tools. The modular structure of the upper mounting plate 641 and the lower mounting plate 645 makes the replacement of the crushing blade assembly 56 convenient and effectively improves maintenance efficiency.

[0038] As one of the preferred embodiments of this utility model, fixing strips 7 connected to the outer surface of the crushing box 3 are symmetrically arranged at the longitudinal gaps between the mounting plate 64 and the pull-out port 32 and the fixing port 33, and threaded fixing bolts 71 are provided through the fixing strips 7.

[0039] When the mounting plate 64 is inserted into the crushing box 3 through the pull-out port 32 and the fixing port 33, it forms an initial positioning with the longitudinal gap between the pull-out port 32 and the fixing port 33. The fixing strips 7 at the longitudinal gap between the mounting plate 64 and the pull-out port 32 and the fixing port 33 are aligned with each other. Then, the fixing bolts 71 pass through the fixing strips 7 and engage with them with the threads, thereby fixing the two fixing strips 7 together, so that the mounting plate 64 is firmly locked in the pull-out port 32 and the fixing port 33. The fixing strips 7 at the pull-out port 32 and the fixing port 33 form a double-end constraint, thereby improving the stability of the crushing assembly 5 installation.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
