Description

Technical Field

[0001] The invention relates to the technical field of camouflage net crushing and recycling, and in particular to a crushing and recycling machine for camouflage net waste. Background Art

[0002] Camouflage nets are an important type of camouflage barrier equipment. They are a protective measure for military targets such as weapons and equipment, military facilities, etc. on the battlefield. Camouflage nets are indispensable in many fields such as military, outdoor film and television shooting, hunting, etc. Camouflage nets are usually made of high-strength, wear-resistant and special optical synthetic fiber materials, and are added with pigments, UV-resistant agents and other chemical substances to achieve camouflage functions.

[0003] With the continuous development and upgrading of application scenarios, a large number of camouflage nets have been abandoned due to obsolescence, resulting in a considerable amount of camouflage net waste. If not properly handled, it will not only take up a lot of space, but may also have adverse effects on the environment. Currently, most of the waste is disposed of by landfill or incineration. In the process of handling camouflage net waste, the camouflage net must first be crushed and recycled, so a crushing and recycling machine is required.

[0004] Currently, most of the camouflage nets on the market are crushed by driving two crushing rollers to rotate. However, when processing camouflage net waste, due to the strong toughness and complex structure of the camouflage net, the equipment is prone to jamming and incomplete crushing, resulting in poor crushing effect. In addition, due to the special material of the camouflage net, it is easy to be entangled on the crushing blades during the crushing process, thereby affecting the stability of the crushing. In addition, it is difficult for the blades of the equipment to accurately act on various parts of the camouflage net, resulting in the recycled material failing to meet the expected particle size requirements, resulting in uneven particle size of the crushed material, which cannot meet the requirements of subsequent recycling.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 9A shredder for recycling camouflage net waste, comprising a shredder body 1, L-shaped support frames 2 are fixed on the inner walls of the opposite sides of the shredder body 1, a mounting roller 4 and a fixed roller 41 are slidably mounted on the L-shaped support frame 2, a rotatable grooved roller 5 is coaxially mounted on the outside of the mounting roller 4, a rotatable ring-knife cutting roller 6 is coaxially mounted on the outside of the fixed roller 41, a plurality of linearly distributed annular blades 601 are mounted on the annular knife cutting roller 6, a plurality of cutting grooves 51 are opened on the grooved roller 5, the positions of the annular blades 601 are corresponding to the positions of the cutting grooves 51, and a plurality of grooved rollers 5 are opened inside The chute 52, multiple chute 52 are equipped with multiple movable supporting rods 7. In the multiple chute 52 inside the grooved roller 5, the supporting rods 7 are distributed in the form of multiple annular arrays, aiming to provide support and positioning for the camouflage net body 8 sleeved thereon more evenly and stably, and each supporting rod 7 in the next row is located exactly at the interval between two adjacent supporting rods 7 in the first row. Such a staggered arrangement makes the overall distribution of the supporting rods 7 in the grooved roller 5 more compact and reasonable, and can undertake and assist in positioning the camouflage net body 8 from more directions. When viewed from a top-down angle, it is like cleverly integrating two different numbers of mutually nested annular structures, so that the camouflage net body 8 can be more fully supported when placed on the supporting rod 7, avoiding the situation of partial suspension or uneven force, and laying a good foundation for subsequent operations such as straightening and cutting.

[0023] The camouflage net body 8 is sleeved on the supporting rod 7, and a plurality of slot blocking blocks 74 are slidably connected in the slide slot 52; A crushing and recycling machine for camouflage net waste also includes a regulating mechanism, a stretching mechanism, an adjustment mechanism, a lifting and collecting mechanism and a feeding mechanism.

[0024] It should be noted that there are a variety of practical ways to drive the grooved roller 5 and the ring knife cutting roller 6. In actual application, they can be flexibly selected in combination with specific working conditions and actual needs.

[0025] The following are two common and practical examples of driving methods: Drive mode 1: synchronous belt drive mode, install the motor at a suitable place on the outside of the crusher body 1. For example, a motor mounting seat can be set on one of the side walls of the crusher body 1 by welding or bolting, and then the reduction motor can be firmly fixed on the mounting seat. After completing the reasonable installation of the motor, start to build a synchronous belt transmission system. The specific operation is to accurately install an active synchronous pulley on the output shaft of the motor, and then install the corresponding driven synchronous pulleys at one end of the grooved roller 5 and the ring knife cutting roller 6 (this end needs to avoid the part where they are connected to the installation roller 4 and the fixed roller 41). Then, according to the actual power required to be transmitted, the desired speed requirements, and the center distance between the two rollers and other key parameters, carefully select the synchronous belt of appropriate specifications. For example, comprehensively consider the above factors to determine the specific model and appropriate length of the synchronous belt, so as to ensure the adaptability and efficiency of the entire transmission system. Finally, the driving synchronous pulley is reliably connected to the two driven synchronous pulleys through the synchronous belt. In this way, with the advantages of precise transmission ratio, high transmission efficiency and good buffering and vibration absorption of the synchronous belt transmission, the synchronous rotation of the grooved roller 5 and the ring knife cutting roller 6 can be effectively achieved.

[0026] Drive mode 2: Gear transmission mode, a gear is installed on the output shaft of the motor, and then the grooved roller 5 and the ring knife cutting roller 6 are respectively sleeved with large gear rings that mesh with each other. Through rigorous and accurate parameter calculation and layout planning, it is ensured that the large gear rings sleeved on the grooved roller 5 and the ring knife cutting roller 6 can rotate synchronously, thereby driving the grooved roller 5 and the ring knife cutting roller 6 to achieve synchronous operation as expected.

[0027] Since the rotation mode of the grooved roller 5 and the ring knife cutting roller 6 has been relatively maturely applied and implemented in various ways in the relevant technical field, and is not the core innovative point of the present invention, its specific details and various conventional implementation methods will not be elaborated here.

[0028] The adjusting mechanism is used to control the removal and disassembly of the installation roller 4 and the fixed roller 41. The adjusting mechanism includes a vertical moving part and a horizontal moving part. The vertical moving part is used to drive the fixed roller 41 and the installation roller 4 to slide vertically. The vertical moving part drives the slider 23 to move up and down with the help of a screw rod 22 rotatably connected between two support plates 21 fixed on the top surface of the L-shaped support frame 2. The slider 23 is connected to the slide bar 25 via a telescopic rod 24. The two groups of connecting columns 3 at the bottom of the slide bar 25 are respectively rotatably connected to the installation roller 4 and the fixed roller 41 to achieve vertical sliding of the fixed roller 41 and the installation roller 4; the horizontal moving part relies on the threaded rod 26 rotatably connected to the slide bar 23 to cooperate with the thread in the hollow slide bar 25, and uses the L-shaped groove in the L-shaped support frame 2 to achieve horizontal sliding of the fixed roller 41 and the installation roller 4, thereby facilitating the removal and disassembly of the installation roller 4 and the fixed roller 41, which is beneficial to the maintenance and overhaul of the equipment.

[0029] The vertical moving part includes a support plate 21 fixed on the top surface of the L-shaped support frame 2. There are two support plates 21. A screw rod 22 is rotatably connected between the two support plates 21. A slider 23 is threadedly connected to the screw rod 22. A telescopic rod 24 is fixed to the bottom surface of the slider 23. The telescopic rod 24 can be extended and retracted within a certain range to adapt to the slight position changes or installation errors that may occur in the equipment under different working conditions. At the same time, it plays a role of buffering and connection to avoid damage between components due to excessive force caused by rigid connection. A slide bar 25 is fixed to the bottom surface of the telescopic rod 24. A connecting column 3 is fixed to the bottom surface of the slide bar 25. The connecting column 3 is symmetrically provided in two groups. The two groups of connecting columns 3 are rotatably connected to the installation roller 4 and the fixed roller 41 respectively. A notch is provided in the L-shaped support frame 2 to facilitate the horizontal sliding of the screw rod 22; The horizontal moving part is used to drive the fixed roller 41 and the installation roller 4 to slide horizontally. The horizontal sliding part includes a threaded rod 26 rotatably connected to the slider 23. The sliding rod 25 is hollow and has an external thread that matches the threaded rod 26. The L-shaped support frame 2 is provided with an L-shaped groove to facilitate the sliding of the connecting column 3.

[0030] The stretching mechanism is used to straighten and cut the camouflage net body 8. The stretching mechanism is composed of multiple sleeves 53, multiple connecting rods 55 and limiters. The starting end sleeve 53 is fixedly connected to the grooved roller 5. The sleeve 53 at the starting end is fixedly connected to the grooved roller 5 to ensure that there is a relatively stable starting reference point during the entire stretching process. The remaining multiple sleeves 53 are placed in the slide groove 52 of the grooved roller 5 for sliding connection. This sliding connection method allows the sleeve 53 to flexibly adjust its position in the slide groove 52 according to the movement of the connecting rod 55 and the force of the camouflage net body 8, while ensuring smooth relative movement with the grooved roller 5 without jamming. The remaining multiple sleeves 53 are placed in the slide groove 52 for sliding connection, multiple connecting rods 55 are sleeved with the sleeve 53, and multiple connecting rods 55 are hingedly arranged. Multiple connecting rods 55 are sleeved with the sleeve 53 and hinged with each other. The hinged connection method allows the connecting rods 55 to rotate relative to each other, so that the angle of the sleeve 53 can be flexibly adjusted according to the displacement change of the sleeve 53 at different positions to achieve coordinated movement.

[0031] The limiting member includes a fixed rod 58 fixed to the side wall of the grooved roller 5, a stopper 59 is threadedly rotated on the fixed rod 58, an L-shaped connecting plate 56 is fixed to the end side of the connecting rod 55, and an insertion opening 57 is provided on the L-shaped connecting plate 56, and the insertion opening 57 is matched with the shape of the stopper 59. The limiting member provides a reliable installation foundation for the stopper 59, and the position of the stopper 59 on the fixed rod 58 can be flexibly adjusted by threading the stopper 59 on the fixed rod 58, thereby limiting the range of motion of the connecting rod 55.

[0032] The adjustment mechanism is used to adjust and install the annular blade 601, which is divided into an upper blade and a lower blade. The adjustment mechanism is composed of a precision adjustment component and a disassembly component. The precision adjustment component is used to synchronously drive and adjust the position spacing of multiple upper blades and lower blades. The precision adjustment component includes a rotating shaft 61, which is rotatably connected to the fixed roller 41. The rotating shaft 61 is provided with multiple sections of symmetrical bidirectional screw grooves 62. The bidirectional screw grooves 62 are relatively threadedly sleeved with a first adjustment piece 63 and a second adjustment piece 65. The first adjustment piece 63 is connected to the upper blade, and the second adjustment piece 65 is connected to the lower blade. The end side of the first adjustment piece 63 is fixed with an outer protruding piece 64, and the end side of the second adjustment piece 65 is fixed with an inner embedded piece 66. The outer wall of the inner embedded piece 66 fits and slides with the inner wall of the outer protruding piece 64, and the inner embedded piece 66 is retracted in the outer protruding piece 64. This special matching relationship ensures the accuracy and stability when adjusting the spacing between the upper blade and the lower blade. The fitting surface between the outer protruding piece 64 and the inner embedded piece 66 has been precisely processed to prevent the two from being offset or misaligned during relative movement, so that the upper blade and the lower blade can always remain relatively parallel and evenly spaced, ensuring that the cutting force at each part during the cutting process is uniform, improving the cutting quality, and reducing problems such as incomplete cutting and poor crushing effect caused by uneven blade spacing.

[0033] The disassembly assembly is used to disassemble and replace the upper blade and the lower blade. The disassembly assembly includes a first connecting block 67 and a second connecting block 68. The first connecting block 67 and the second connecting block 68 are respectively installed on the upper blade and the lower blade. The first connecting block 67 is fitted with the second connecting block 68, and a screw 69 passes through the first connecting block 67 and the second connecting block 68.

[0034] The lifting and retracting mechanism is used to alternately eject and retract the jacking rod 7 and the slot blocking block 74. The lifting and retracting mechanism includes a circular plate 73, a block lifting and retracting piece and a rod lifting and retracting piece. The circular plate 73 is fixed in the grooved roller 5. The main function of the circular plate 73 is to provide a stable sliding space and installation foundation for the slot blocking block 74 and the jacking rod 7. At the same time, it also plays a positioning and supporting role for the internal springs, special-shaped eccentric wheels, special-shaped cams and other related components to ensure that the relative position relationship between the various components of the entire lifting and retracting mechanism is accurate and the coordinated work is smooth. A circular groove is provided in the circular plate 73, and the slot blocking block 74 and the supporting rod 7 are placed in the circular groove for sliding. The block top receiving piece includes a movable rod 741 and a first special-shaped cam 744. The movable rod 741 is fixed on the bottom surface of the circular plate 73, and a round table 742 is fixed on the bottom surface of the movable rod 741. A first spring 743 is fixed on the top surface of the round table 742. The other end of the first spring 743 is fixedly connected to the circular plate 73. The first special-shaped cam 744 is fixedly sleeved on the mounting roller 4. The top of the first special-shaped cam 744 is provided with a micro-arc surface protruding upward, and the arc surface connection is a concave arc surface, and the concave arc surface is truncated in a curved arc and protrudes outward. The upward protruding part of the micro-arc surface can provide a large thrust when it contacts the truncated table 742, so that the slot blocking block 74 can be ejected quickly; the concave arc surface at the arc surface connection and the curved arc at the concave arc surface truncation are arranged to protrude outward, so that the movement state of the truncated table 742 can be smoothly transitioned when passing through these parts, avoiding severe impact and jamming, and ensuring the movement continuity and stability of the slot blocking block 74.

[0035] The rod top receiving component includes a connecting platform 71, a second spring 752 and a second special-shaped cam 753. The connecting block is fixed to the bottom surface of the supporting rod 7. The outer wall of the supporting rod 7 is sleeved with a compression spring 72. The two ends of the compression spring 72 are respectively fixedly connected to the top surface of the connecting platform 71 and the bottom surface of the sleeve 53. The second spring 752 is fixed to the top surface of the circular plate 73. The other end of the second spring 752 is fixed with a connecting strip 751. A push rod 75 is fixed in the middle of the connecting strip 751. A protrusion 76 is fixed on the top surface of the push rod 75. The protrusion 76 is in the same vertical direction as the supporting rod 7. The second special-shaped cam 753 is fixedly sleeved on the mounting roller 4. The top of the second special-shaped cam 753 is concave in a semi-arc surface, and the end side connection is convex outward in an arc surface, and the protrusion cuts off the link in a concave arc surface. The protrusion of the first special-shaped cam 744 is corresponding to the concave part of the second special-shaped cam 753. The stability of the supporting rod 7 during the sliding process and the coordination with other components are ensured, so that the supporting rod 7 can exert appropriate support and tension on the camouflage net body 8.

[0036] The feeding mechanism is used to flatten and feed the camouflage net body 8. The feeding mechanism includes a lifting member and a clamping member. The lifting member is used to drive the camouflage net body 8 to lift and lay flat. The lifting member includes a fixed block 81. The fixed block 81 is fixed on the side wall of the crusher body 1. The top surface of the fixed block 81 is respectively fixed with a support rod 82 and a hydraulic cylinder 83. The output end of the hydraulic cylinder 83 is fixedly connected to a piston rod 831, and the top of the piston rod 831 is fixedly sleeved with a connecting frame 84.

[0037] The clamping member is used to clamp and fix the camouflage net body 8. The clamping member includes a block 85 fixed to the side wall of the connecting frame 84. Two blocks 85 are symmetrically installed. The two blocks 85 are spliced ​​in a concave shape. An electric push rod 86 is fixed on the upper block 85. A clamping plate 87 is fixed on the bottom surface of the electric push rod 86. The clamping plate 87 fits the camouflage net body 8.

[0038] The present invention can be explained by the following operation mode: First, the cutting accuracy between the upper blade and the lower blade of the ring knife cutting roller 6 is precisely adjusted according to the actual crushing needs. The threaded rod 26 on the slider 23 is rotated. Under the action of the threaded cooperation, the slider 25 will be subjected to the corresponding force, thereby driving the connecting column 3 connected thereto to slide upward in the vertical direction. In this process, the connecting column 3 will squeeze the telescopic rod 24 connected thereto. At the same time, the installation roller 4 on the end side of the connecting column 3 will also move upward synchronously with the upward sliding of the connecting column 3, and the connecting column 3 will slide smoothly along the L-shaped groove provided on the L-shaped support frame 2. When sliding to the bend of the L-shaped groove, the staff manually rotates the screw 22 between the two support plates 21, and the slider 23 is prompted to slide horizontally by means of the threaded transmission action between the screw 22 and the slider 23, and finally drives the installation roller 4 to slide smoothly out of the crusher body 1, so as to make detailed adjustments to the blade cutting accuracy later.

[0039] When adjusting the cutting accuracy of the upper blade and the lower blade, the rotating shaft 61 on the fixed roller 41 is rotated. Since the rotating shaft 61 is provided with multiple symmetrical bidirectional screw grooves 62, and the bidirectional screw grooves 62 are relatively threadedly sleeved with a first adjusting piece 63 and a second adjusting piece 65 (the first adjusting piece 63 is connected to the upper blade, and the second adjusting piece 65 is connected to the lower blade), as the rotating shaft 61 rotates, the first adjusting piece 63 and the second adjusting piece 65 will move relatively according to the thread direction of the bidirectional screw groove 62, thereby realizing synchronous and precise adjustment of the position spacing of the upper blade and the lower blade, laying a good foundation for the subsequent precise cutting of the camouflage net body 8.

[0040] After completing the above preparations, the hydraulic cylinder 83 is started. Driven by the hydraulic power, the piston rod 831 will extend upward, thereby driving the connecting frame 84 fixedly sleeved on the top thereof to slide upward along the corresponding track, so that it is separated from the upper area of ​​the crusher body 1. At this time, the camouflage net to be crushed is carefully placed between the two relatively arranged clamping blocks 85. The two clamping blocks 85 are concave after being spliced, which can play a preliminary positioning role for the camouflage net.

[0041] Then, the electric push rod 86 is started, and the push rod of the electric push rod 86 extends downward, pushing the pressing plate 87 at the bottom thereof to slowly descend until the pressing plate 87 is tightly fitted with the camouflage net, thereby realizing reliable pressing and fixing of the camouflage net. Then, the hydraulic cylinder 83 is started again to make it recover, and the piston rod 831 drives the already compressed camouflage net to slowly slide down along the predetermined track until it falls onto the grooved roller 5, at which time the mesh on the camouflage net will be accurately covered on the corresponding multiple supporting rods 7 that have not yet been stretched.

[0042] Next, the camouflage net is stretched straight. The staff manually pulls the L-shaped connecting plate 56. During this process, the sleeve 53 fixedly connected to the grooved roller 5 at the starting end remains stationary, while the remaining sleeves 53 placed in the slide groove 52 and slidably connected thereto begin to adjust their positions accordingly under the coordinated action of the connecting rod 55. When the camouflage net is stretched straight, the insertion opening 57 on the L-shaped connecting plate 56 is passed through the stop block 59, and then the stop block 59 is rotated to form an interlaced state with the insertion opening 57. Through such a setting, the range of motion of the connecting rod 55 can be effectively limited, so that multiple connecting rods 55 can work together to stretch the camouflage net body 8 straight.

[0043] After the above-mentioned preparations for loading and straightening are completed, the grooved roller 5 and the ring-knife cutting roller 6 are driven to rotate by an external driving device (such as a motor, etc.). It is worth noting that the internal mounting roller 4 and the fixed roller 41 remain stationary at this time. When the grooved roller 5 and the ring-knife cutting roller 6 rotate, the annular blade 601 on the ring-knife cutting roller 6 and the cutting groove 51 on the grooved roller 5 will accurately cooperate with each other to cut and crush the camouflage net together.

[0044] At the same time, the movable rod 741 and the top rod 75 will always slide along the surface of the first special-shaped cam 744 and the second special-shaped cam 753 to achieve a specific function. When the grooved roller 5 drives the distributed and straightened camouflage net body 8 to rotate, the top rod 75 will slide along the protruding part of the second special-shaped cam 753, and the second spring 752 will be stretched in this process. With the elastic force of the second spring 752, it can ensure that the camouflage net always remains stable and straight, so that it can be smoothly transported to the cutting area.

[0045] As the grooved roller 5 continues to rotate, when the camouflage net rotates to the position where it meshes with the ring knife cutting roller 6, the push rod 75 will slide along the concave part of the second special-shaped cam 753, and the resistance force on the push rod 75 will be released, and the second spring 752 will release the accumulated pressure, driving the push rod 75 to return to the initial position, so that it can smoothly slide into the concave part of the circular plate 73. In this way, the protrusion 76 will be separated from the connecting platform 71 on the bottom surface of the lifting rod 7, and the squeezing force on the compression spring 72 will be released, thereby driving the lifting rod 7 to slide into the sleeve 53, and releasing the pulling effect on the camouflage net.

[0046] At the same time, the meshing force generated by the meshing of the grooved roller 5 and the ring knife cutting roller 6 can effectively clamp the camouflage net, so that it remains stable during the cutting process. In addition, during the recovery of the jacking rod 7, the movable rod 741 will slide along the first special-shaped cam 744. When the jacking rod 7 rotates to the recessed part of the second special-shaped cam 753, the movable rod 741 just rotates to the outward protrusion of the first special-shaped cam 744. At this time, the movable rod 741 will be subjected to a corresponding force, thereby driving the slot blocking block 74 to slide upward and squeeze the first spring 743, so that the slot blocking block 74 can smoothly enter the chute 52 and timely block the slot. In this way, the camouflage net can be effectively prevented from entering the grooved roller 5 through the chute 52 during the cutting process. In addition, during the cutting process, the contraction of the slot blocking block 74 can also clean the camouflage net belt that may be entangled on the grooved roller 5 to prevent its entanglement from further aggravating, thereby avoiding adverse effects on the subsequent crushing effect.

[0047] When the device is used for a long time and the annular blade 601 is worn or damaged and needs to be replaced, the operation process is very convenient. Just use the corresponding tools to remove the screws 69 in the disassembly assembly, separate the first connecting block 67 and the second connecting block 68 installed on the upper blade and the lower blade respectively, and then you can easily remove the upper blade and the lower blade, and then replace the new annular blade 601, ensuring that the device can continue to maintain good crushing performance and avoid affecting the subsequent crushing effect due to damage to the annular blade.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
