Description

Technical Field

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

[0002] A camouflage net is an important camouflage barrier equipment and a protective measure for military targets such as weapons and military facilities on the battlefield. In many fields such as military, outdoor film shooting, and hunting, the camouflage net has an indispensable position. The camouflage net is usually made of synthetic fiber materials with high strength, wear resistance, and special optical properties, and is added with various chemical substances such as pigments and ultraviolet absorbers to achieve the camouflage function.

[0003] With the continuous development and replacement of application scenarios, a large number of camouflage nets have been discarded due to obsolescence, forming a considerable amount of camouflage net waste materials. If not properly treated, it will not only occupy a large amount of space but also may have an adverse impact on the environment. Currently, most of the waste materials are treated by landfill or incineration. During the treatment of camouflage net waste materials, the camouflage net needs to be crushed and recycled first, so a crushing and recycling machine is required.

[0004] Currently, when crushing camouflage nets on the market, most of them are crushed by driving two crushing roller knives to rotate. However, when dealing with camouflage net waste materials, due to the strong toughness and complex structure of the camouflage net, it is easy to have situations such as equipment jamming and incomplete crushing, resulting in poor crushing effects. Moreover, due to the special nature of the camouflage net material, it is easy to entangle on the crushing blades during the crushing process, thereby affecting the stability of crushing. And the blades of the equipment are difficult to accurately act on each part of the camouflage net, resulting in the recycled materials not meeting the expected particle size requirements, and the particle size of the crushed materials is uneven, unable to meet the requirements of subsequent recycling and utilization. Summary of the Invention

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] 1. The present invention can accurately adjust the cutting accuracy between the upper blade and the lower blade of the ring cutting roller according to actual crushing requirements. And in the whole crushing process, through a series of orderly operations such as feeding and straightening, the camouflage net is cut and crushed in a stable and proper state, greatly improving the crushing effect, making the particle size of the crushed material more uniform, effectively meeting the requirements of the subsequent recycling for the particle size of the material, and improving the resource recycling value of the camouflage net waste.

[0038] 2.

When the top support rod is retracted, the groove blocking block will slide upward under the drive of the movable rod and enter the chute. It can not only timely block the notch to prevent the camouflage net from entering the inside of the grooved roller, but also clean the camouflage net belt that may be wound on the grooved roller during the contraction process, avoiding the aggravation of the winding situation, thus ensuring that the grooved roller and the ring cutting roller can rotate continuously and stably, maintaining the stability of the entire crushing process, reducing problems such as equipment jamming caused by winding, and ensuring the efficient and stable operation of the equipment.

[0039] 3. In the present invention, through the combined use of the adjustment mechanism and the disassembly and assembly components, the ring cutting roller can be slid out of the machine body so that the staff can disassemble and replace it. This convenient operation method greatly reduces the maintenance difficulty and cost of the equipment, shortens the downtime caused by blade problems, ensures that the equipment can continuously maintain good crushing performance, and is stably put into the crushing and recycling work of camouflage net waste for a long time, improving the overall production efficiency and equipment utilization rate.

Specific embodiments

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0052] Refer to Figures 1 - 9, A crushing and recycling machine for camouflage net waste, including a crusher body 1. On the inner walls of the opposite sides of the crusher body 1, L-shaped support frames 2 are fixed. An installation roller 4 and a fixed roller 41 are slidably installed on the L-shaped support frames 2. An outer coaxial rotating grooved roller 5 is installed outside the installation roller 4. An outer coaxial rotating ring cutting roller 6 is installed outside the fixed roller 41. A plurality of annular blades 601 arranged linearly are installed on the ring cutting roller 6. A plurality of cutting grooves 51 are opened on the grooved roller 5. The positions of the annular blades 601 correspond to the positions of the cutting grooves 51. A plurality of chutes 52 are opened inside the grooved roller 5. A plurality of movable supporting rods 7 are installed in each of the plurality of chutes 52. Inside the plurality of chutes 52 inside the grooved roller 5, the supporting rods 7 are distributed in a plurality of annular arrays, aiming to provide more uniform and stable support and positioning for the camouflage net body 8 sleeved thereon. And each supporting rod 7 in the lower row is exactly located at the interval position between two adjacent supporting rods 7 in the first row. Such staggered setting makes the overall distribution of the supporting rods 7 in the grooved roller 5 more compact and reasonable, and can receive and assist in positioning the camouflage net body 8 from more directions. Observed from a top view, it is like a clever fusion of two ring structures with different numbers and nested with each other. When the camouflage net body 8 is placed on the supporting rods 7, it can be more fully supported, avoiding local suspension or uneven stress, laying a good foundation for subsequent operations such as straightening and cutting.

[0053] The camouflage net body 8 is sleeved on the supporting rod 7, and a plurality of groove blocking blocks 74 are slidably connected in the chute 52;

[0054] A crushing and recycling machine for camouflage net waste further includes an adjusting mechanism, a stretching mechanism, an adjusting mechanism, a top receiving mechanism and a feeding mechanism.

[0055] It should be noted that there are various practical ways to drive the rotation of the grooved roller 5 and the ring cutting roller 6. In the actual application process, it can be flexibly selected in combination with specific working conditions and actual requirements.

[0056] The following are two common and practical driving method examples:

[0057] Driving method 1: Synchronous belt drive method. Install the motor at a suitable location outside the crusher body 1. For example, a motor mounting seat can be set on one side wall of the crusher body 1 by welding or bolt fixing, and then the reduction motor is firmly fixed on this mounting seat. After the motor is reasonably installed, start to construct the synchronous belt drive system. Specifically, a driving synchronous belt pulley is accurately installed on the output shaft of the motor. Then, on one end of the grooved roller 5 and the ring cutting roller 6 (this end needs to avoid the parts where they are connected to the mounting roller 4 and the fixed roller 41), the corresponding driven synchronous belt pulleys are installed respectively. Then, according to the key parameters such as the actual required transmitted power, the expected rotational speed requirements, and the center distance between the two rollers, a synchronous belt of appropriate specifications is carefully selected. For example, considering the above factors to determine the specific model and suitable length of the synchronous belt, etc., to ensure the adaptability and high efficiency of the entire drive system. Finally, the driving synchronous belt pulley is reliably connected to the two driven synchronous belt pulleys through the synchronous belt. In this way, by virtue of the advantages of the synchronous belt drive such as accurate transmission ratio, high transmission efficiency, and good buffering and vibration absorption, the synchronous rotation of the grooved roller 5 and the ring cutting roller 6 can be effectively realized.

[0058] Driving method 2: Gear drive method. Install a gear on the output shaft of the motor. Then, for the grooved roller 5 and the ring cutting roller 6, large gear rings meshing with them are respectively sleeved on them. 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 cutting roller 6 can rotate synchronously, and then drive the grooved roller 5 and the ring cutting roller 6 to run synchronously as expected.

[0059] Since the rotation modes of the grooved roller 5 and the ring cutting roller 6 have relatively mature applications and various implementation ways in the related technical fields, and they are not the core innovation points of the present invention, their specific details and various conventional implementation ways will not be elaborated in detail here.

[0060] The adjusting mechanism is used to control the removal and installation of the mounting 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 mounting roller 4 to slide vertically. The vertical moving part drives the slider 23 to move up and down by means 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 a slide bar 25 through a telescopic rod 24. Two groups of connecting columns 3 at the bottom of the slide bar 25 are respectively rotatably connected to the mounting roller 4 and the fixed roller 41, realizing the vertical sliding of the fixed roller 41 and the mounting roller 4. The horizontal moving part relies on the threaded cooperation between a threaded rod 26 rotatably connected to the slider 23 and the thread inside the hollow slide bar 25, and uses the L-shaped groove inside the L-shaped support frame 2 to achieve the horizontal sliding of the fixed roller 41 and the mounting roller 4, so as to facilitate the removal and installation of the mounting roller 4 and the fixed roller 41, and is conducive to the maintenance and repair of the equipment.

[0061] The vertical moving member includes a support plate 21 fixed to 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. An expansion rod 24 is fixed to the bottom surface of the slider 23. The expansion rod 24 can expand and contract within a certain range to adapt to the slight position changes or installation errors that may occur under different working conditions of the equipment. At the same time, it plays a role in buffering and connecting, avoiding damage caused by excessive force between components due to rigid connection. A sliding rod 25 is fixed to the bottom surface of the expansion rod 24. A connecting column 3 is fixed to the bottom surface of the sliding rod 25. There are two sets of symmetrically arranged connecting columns 3. The two sets of connecting columns 3 are respectively rotatably connected to the mounting roller 4 and the fixed roller 41. A notch is provided in the L-shaped support frame 2 to facilitate the horizontal sliding of the expansion rod 24;

[0062] The horizontal moving member is used to drive the fixed roller 41 and the mounting roller 4 to slide horizontally. The horizontal sliding member includes a threaded rod 26 rotatably connected to the slider 23. The sliding rod 25 is hollow inside. An internal thread that is threadedly engaged with the threaded rod 26 is provided inside the sliding rod 25. An L-shaped groove is provided in the L-shaped support frame 2 to facilitate the sliding of the connecting column 3.

[0063] The stretching mechanism is used to straighten and cut the camouflage net body 8. The stretching mechanism is composed of a plurality of sleeves 53, a plurality of connecting rods 55 and a limiting member. The starting-end sleeve 53 is fixedly connected to the grooved roller 5. The starting-end sleeve 53 is fixedly connected to the grooved roller 5 to ensure a relatively stable starting reference point during the entire stretching process. The remaining plurality of sleeves 53 are slidably connected in the chute 52 of the grooved roller 5. This sliding connection method enables the sleeve 53 to flexibly adjust its position in the chute 52 according to the movement of the connecting rod 55 and the force condition of the camouflage net body 8, while ensuring smooth relative movement with the grooved roller 5 without jamming. The remaining plurality of sleeves 53 are slidably connected in the chute 52. A plurality of connecting rods 55 are sleeved on the sleeves 53, and the plurality of connecting rods 55 are hinged to each other. The hinged connection method enables the connecting rods 55 to rotate relative to each other, so that they can flexibly adjust their own angles according to the displacement changes of the sleeves 53 at different positions and achieve coordinated movement.

[0064] The limiting member includes a fixed rod 58 fixed to the side wall of the grooved roller 5. A blocking block 59 is rotatably threaded on the fixed rod 58. An L-shaped connecting plate 56 is fixed to the end side of the connecting rod 55. An insertion opening 57 is provided on the L-shaped connecting plate 56. The insertion opening 57 is arranged to match the shape of the blocking block 59. The limiting member provides a reliable installation basis for the blocking block 59. By rotatably threading the blocking block 59 on the fixed rod 58, the position of the blocking block 59 on the fixed rod 58 can be flexibly adjusted to limit the movement range of the connecting rod 55.

[0065] The adjustment mechanism is used to adjust and install the annular blade 601. The annular blade 601 is divided into an upper blade and a lower blade. The adjustment mechanism consists of a precision adjustment component and a disassembly and assembly component. The precision adjustment component is used to synchronously drive and adjust the position spacing between multiple upper blades and lower blades. The precision adjustment component includes a rotating shaft 61, which is rotatably connected to the fixed roller 41. Multiple sections of symmetric bidirectional screw grooves 62 are provided on the rotating shaft 61. A first adjustment piece 63 and a second adjustment piece 65 are relatively thread-sleeved on the bidirectional screw grooves 62. The first adjustment piece 63 is connected to the upper blade, and the second adjustment piece 65 is connected to the lower blade. An outer convex piece 64 is fixed on the end side of the first adjustment piece 63, and an inner embedded piece 66 is fixed on the end side of the second adjustment piece 65. The outer wall of the inner embedded piece 66 is in sliding fit with the inner wall of the outer convex piece 64, and the inner embedded piece 66 is retracted into the outer convex piece 64. This special mating relationship ensures the accuracy and stability when adjusting the spacing between the upper blade and the lower blade. The mating surface between the outer convex piece 64 and the inner embedded piece 66 is precision machined, which can prevent the two from shifting or misaligning during relative movement, enabling the upper blade and the lower blade to always maintain a relatively parallel state with a uniform spacing, ensuring that the cutting force at each part is uniform during the cutting process, improving the cutting quality, and reducing problems such as incomplete cutting and poor crushing effect caused by uneven blade spacing.

[0066] The disassembly and assembly component is used to disassemble, assemble and replace the upper blade and the lower blade. The disassembly and assembly component includes a first connection block 67 and a second connection block 68. The first connection block 67 and the second connection block 68 are respectively installed on the upper blade and the lower blade. The first connection block 67 is in contact with the second connection block 68, and a screw 69 passes through between the first connection block 67 and the second connection block 68.

[0067] The top receiving mechanism is used to alternately eject and retract the top supporting rod 7 and the groove blocking block 74. The top receiving mechanism consists of a U-shaped plate 73, a block top receiving part, and a rod top receiving part. The U-shaped plate 73 is fixed inside the grooved roller 5. The main function of the U-shaped plate 73 is to provide a stable sliding space and an installation base for the groove blocking block 74 and the top supporting rod 7. At the same time, it also plays a role in positioning and supporting the internal spring, special-shaped eccentric wheel, special-shaped cam and other related components, ensuring the accurate relative position relationship between the components of the entire top receiving mechanism and the smooth cooperation of the components. There is a U-shaped groove inside the U-shaped plate 73, and the groove blocking block 74 and the top supporting rod 7 are placed in the U-shaped groove to slide. The block top receiving part includes a movable rod 741 and a first special-shaped cam 744. The movable rod 741 is fixed on the bottom surface of the groove blocking block 74. 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 with the U-shaped plate 73. The first special-shaped cam 744 is fixedly sleeved on the installation roller 4. The top of the first special-shaped cam 744 is provided with a slightly convex arc surface, and the arc surface connection part is a concave arc surface, and the cut-off part of the concave arc surface is provided with a curved arc protruding outward. When the slightly convex arc surface contacts the round table 742, it can provide a large thrust force to quickly eject the groove blocking block 74. The concave arc surface at the arc surface connection part and the curved arc protruding outward at the cut-off part of the concave arc surface enable the round table 742 to smoothly transition its motion state when passing through these parts, avoiding violent impacts and jamming phenomena, and ensuring the continuity and stability of the movement of the groove blocking block 74.

[0068] The rod top receiving part includes a connecting platform 71, a second spring 752, and a second special-shaped cam 753. The connecting block is fixed on the bottom surface of the top supporting rod 7. A compression spring 72 is sleeved on the outer wall of the top supporting rod 7. The two ends of the compression spring 72 are respectively fixedly connected with the top surface of the connecting platform 71 and the bottom surface of the sleeve 53. The second spring 752 is fixed on the top surface of the U-shaped plate 73. A connecting bar 751 is fixed at the other end of the second spring 752. A top rod 75 is fixed in the middle of the connecting bar 751. A convex block 76 is fixed on the top surface of the top rod 75. The convex block 76 and the top supporting rod 7 are in the same vertical direction. The second special-shaped cam 753 is fixedly sleeved on the installation roller 4. The outer wall of the second special-shaped cam 753 is set with a semi-circular arc surface depression, resulting in a continuous outer convex and concave surface on the outer wall of the second special-shaped cam 753. The convex part of the first special-shaped cam 744 is correspondingly set with the concave part of the second special-shaped cam 753. Ensure the stability of the top supporting rod 7 during the sliding process and its coordinated cooperation with other components, so that the top supporting rod 7 can exert appropriate support and tension on the camouflage net body 8.

[0069] The feeding mechanism is used to level 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 flatten. The lifting member includes a fixed block 81, which 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 with a piston rod 831, and the top of the piston rod 831 is fixedly sleeved with a connecting frame 84.

[0070] The clamping member is used to clamp and fix the camouflage net body 8. The clamping member includes a clamping block 85 fixed on the side wall of the connecting frame 84. Two clamping blocks 85 are symmetrically installed, and the two clamping blocks 85 are spliced into a concave shape. An electric push rod 86 is fixed on the upper clamping block 85, and a pressing plate 87 is fixed on the bottom surface of the electric push rod 86. The pressing plate 87 is in contact with the camouflage net body 8.

[0071] The function principle of the present invention can be elaborated through the following operation modes:

[0072] First of all, according to the actual crushing requirements, accurately adjust the cutting accuracy between the upper blade and the lower blade of the ring cutting roller 6. Rotate the threaded rod 26 on the sliding block 23. Under the action of thread fitting, the sliding rod 25 will be subjected to a corresponding force, and then drive the connecting column 3 connected thereto to slide upward along the vertical direction. During this process, the connecting column 3 will squeeze the telescopic rod 24 connected thereto. At the same time, the mounting roller 4 on the 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 smoothly slide 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 rod 22 between the two support plates 21. By virtue of the thread transmission between the screw rod 22 and the sliding block 23, the sliding block 23 is urged to slide horizontally, and finally drive the mounting roller 4 to smoothly slide out of the crusher body 1 for subsequent fine adjustment of the blade cutting accuracy.

[0073] When adjusting the cutting accuracy of the upper blade and the lower blade, rotate the rotating shaft 61 on the fixed roller 41. Since the rotating shaft 61 is provided with multiple sections of symmetric bidirectional screw grooves 62, and the first adjusting piece 63 and the 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) are relatively sleeved on the bidirectional screw grooves 62. 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 grooves 62, so as to realize the synchronous and accurate adjustment of the position spacing between the upper blade and the lower blade, laying a good foundation for the subsequent precise cutting of the camouflage net body 8.

[0074] After completing the above preparatory work, start the hydraulic cylinder 83. Driven by hydraulic power, the piston rod 831 will extend upward, thereby driving the connecting frame 84 fixedly sleeved on its top to slide upward along the corresponding track, so that it disengages from the area above the crusher body 1. At this time, carefully place the camouflage net to be crushed between the two relatively arranged clamping blocks 85. After being spliced, these two clamping blocks 85 are concave-shaped and can play a preliminary positioning role for the camouflage net.

[0075] Subsequently, start the electric push rod 86. The push rod of the electric push rod 86 will extend downward, pushing the pressing plate 87 at its bottom to slowly descend until the pressing plate 87 is in close contact with the camouflage net, thereby realizing reliable pressing and fixing of the camouflage net. Then, start the hydraulic cylinder 83 again to make it perform a retracting action. The piston rod 831 drives the already pressed camouflage net to slowly slide down along the established track until it falls onto the grooved roller 5. At this time, the mesh holes on the camouflage net will accurately fit over the corresponding and not yet stretched multiple supporting rods 7.

[0076] Immediately afterwards, start the straightening operation on the camouflage net. 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 other sleeves 53 placed in the sliding groove 52 and slidably connected thereto will start to adjust their positions accordingly under the cooperation of the connecting rod 55. When the camouflage net is straightened, make the insertion opening 57 on the L-shaped connecting plate 56 pass through the blocking block 59, and then rotate the blocking block 59 to make it in an interleaved state with the insertion opening 57. Through such a setting, the activity range of the connecting rod 55 can be effectively restricted, and then multiple connecting rods 55 can cooperate to straighten the camouflage net body 8.

[0077] After completing the above feeding and straightening preparatory work, drive the grooved roller 5 and the ring cutting roller 6 to rotate through an external driving device (such as a motor, etc.). It should be noted that at this time, the internal mounting roller 4 and the fixed roller 41 remain stationary. When the grooved roller 5 and the ring cutting roller 6 rotate, the annular blade 601 on the ring cutting roller 6 and the cutting groove 51 on the grooved roller 5 will accurately cooperate with each other to jointly cut and crush the camouflage net.

[0078] Meanwhile, the movable rod 741 and the ejector rod 75 will always slide along the surfaces of the first special-shaped cam 744 and the second special-shaped cam 753 to achieve specific functions. When the grooved roller 5 drives the already distributed and straightened camouflage net body 8 to rotate, the ejector rod 75 will slide along the outwardly convex part of the second special-shaped cam 753. During this process, the second spring 752 will be stretched. With the elastic force of the second spring 752, it can ensure that the camouflage net always remains stable and straightened, so as to be smoothly conveyed to the cutting area.

[0079] 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 ejector rod 75 will slide along the concave part of the second special-shaped cam 753. At this time, the resistance force on the ejector rod 75 will be relieved, and the second spring 752 will release the accumulated pressure, driving the ejector rod 75 back to its initial position so that it can smoothly slide into the concave part in the return plate 73. In this way, the convex block 76 will disengage from the connecting platform 71 on the bottom surface of the supporting rod 7, and the extrusion force on the compression spring 72 will also be relieved, thereby driving the supporting rod 7 to slide into the sleeve 53, releasing the pulling effect on the camouflage net.

[0080] Meanwhile, by using the meshing force generated by the meshing of the grooved roller 5 and the ring knife cutting roller 6, the camouflage net can be effectively clamped to keep it stable during the cutting process. Moreover, during the recovery process of the supporting rod 7, the movable rod 741 will slide along the first special-shaped cam 744. When the supporting rod 7 rotates to the concave part of the second special-shaped cam 753, the movable rod 741 just rotates to the outward convex part of the first special-shaped cam 744. At this time, the movable rod 741 will receive a corresponding force, which will drive the slot-blocking block 74 to slide upward and compress the first spring 743, so that the slot-blocking block 74 can smoothly enter the chute 52 to timely block the slot opening. This can effectively prevent the camouflage net from entering the inside of the grooved roller 5 through the chute 52 opening during the cutting process. Moreover, during the cutting process, the contraction action of the slot-blocking block 74 can also clean the camouflage net belt that may be wound on the grooved roller 5, preventing its winding situation from further intensifying, thereby avoiding having an adverse impact on the subsequent crushing effect.

[0081] When the equipment 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 tool to remove the screw 69 in the disassembly and assembly component, separate the first connecting block 67 and the second connecting block 68 respectively installed on the upper blade and the lower blade, and then the upper blade and the lower blade can be easily removed, and then a new annular blade 601 can be replaced to ensure that the equipment can continuously maintain good crushing performance and avoid affecting the subsequent crushing effect due to the damage of the ring knife blade.

[0082] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered by the protection scope of the present invention.
