Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and in particular to a polypropylene needle-punched geotextile production equipment. Background Technology

[0002] Polypropylene needle-punched geotextile is a high-strength geosynthetic material composed of filament geotextile and needle-punched mesh. The geotextile has excellent tensile strength and elongation, while the needle-punched mesh has high density and excellent tear resistance. It is commonly used in soil protection, conservation, and consolidation projects, effectively protecting the soil from external factors and preventing soil erosion and landslides. During the production process, polypropylene needle-punched geotextile is usually wound up using rollers. When the geotextile reaches a specific length or the upper limit of the roller winding, the roller needs to be replaced. However, the existing winding equipment has a cumbersome roller locking and connection structure, making replacement operation complex, labor-intensive, and reducing the efficiency of replacement work.

[0003] For example, a polypropylene needle-punched geotextile production equipment disclosed in Chinese patent literature (announcement number: CN220334266U) achieves the effect of convenient and quick replacement of the circular roller through the cooperation between the first fixed rod, the first fixed ring, the bolt, the second fixed ring, the card block, the card groove, the driving gear, and the driven gear. The operation is relatively simple, the manpower consumption is small, and the work efficiency is high.

[0004] However, when it is necessary to disassemble the wound-up roller, tools are required to carefully and repeatedly loosen the two bolts. This process not only requires a high level of wrist strength, but also easily causes hand fatigue and soreness due to prolonged repetitive operation. The manual labor is relatively large. Furthermore, due to the compact internal structure of the equipment and the lack of a reasonable removal guide design, the gap between the roller and the surrounding parts is narrow, making it difficult for operators to apply force accurately and remove it smoothly and stably from the equipment. Often, multiple people are required to work together, which makes the operation cumbersome and reduces the continuity of production. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the high manual labor required for disassembling and replacing rollers, the difficulty in removing the disassembled rollers, and the reduced production continuity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A polypropylene needle-punched geotextile production equipment includes a base and a circular roller. The upper end of the base is fixedly connected to symmetrically distributed support blocks. A first mounting hole is opened on one side of the support block. A convenient disassembly mechanism is provided inside the first mounting hole. The convenient disassembly mechanism includes a rotating sleeve. A movable insert is movably sleeved on the inner wall of the rotating sleeve. A support spring is fixedly connected to one end of the movable insert. One end of the support spring is fixedly connected to the inner wall of one side of the rotating sleeve.

[0008] The rotating sleeve has a travel groove on its outer side, and a drive rod is slidably connected to the inner wall of the travel groove. The lower end of the drive rod is fixedly connected to the upper end of the movable insert. An arc-shaped support block is fixedly connected to one end of the rotating sleeve, and a guide post is fixedly connected to the inner wall of the arc-shaped support block.

The inner walls of the two second mounting holes are rotatably connected to rotating rods through bearings.

[0012] Preferably, a worm gear is fixedly sleeved on the outside of the rotating rod, and symmetrically distributed drive pulleys are fixedly sleeved on both ends of the rotating rod, with a synchronous belt externally connected to the drive pulleys.

[0016] In this utility model, the convenient disassembly mechanism enables the rapid installation of the circular roller, which not only reduces manual labor but also improves production efficiency. Furthermore, the automated disassembly of the circular roller that is winding up the geotextile allows it to fall into the arc-shaped support frame and be pushed out of the equipment area, making it easier for operators to remove the geotextile and greatly improving the continuity of production.

[0028] Example

[0029] like Figure 1-6 As shown, this utility model provides a technical solution: a polypropylene needle-punched geotextile production equipment, including a base 1 and a circular roller 2. The upper end of the base 1 is fixedly connected with symmetrically distributed support blocks 3. This symmetrical distribution design can make the equipment bear force evenly and avoid structural deformation or component displacement caused by uneven force.

[0030] A first mounting hole 4 is provided on one side of the support block 3. The first mounting hole 4 is equipped with a convenient disassembly mechanism, which includes a rotating sleeve 5. A movable insert 51 is movably fitted on the inner wall of the rotating sleeve 5. The movable insert 51 is a component that can move flexibly inside the rotating sleeve 5. Its shape and size match the inner wall of the rotating sleeve 5 to ensure the accuracy of the movement. A support spring 52 is fixedly connected to one end of the movable insert 51. One end of the support spring 52 is fixedly connected to the inner wall of one side of the rotating sleeve 5. The support spring 52 plays an important role in elastic support and reset. At different stages of equipment operation, it can store and release elastic potential energy as needed to realize the extension and retraction movement of the movable insert 51.

[0031] The outer side of the rotating sleeve 5 is provided with a stroke groove 53, and the inner wall of the stroke groove 53 is slidably connected to the drive rod 54. The inner wall of the stroke groove 53 is finely polished so that the sliding connection between it and the drive rod 54 is both tight and smooth, avoiding jamming.

[0032] The lower end of the drive rod 54 is fixedly connected to the upper end of the movable insert 51. One end of the rotating sleeve 5 is fixedly connected to an arc-shaped support block 55. The design of the arc-shaped support block 55 fully considers the shape of the roller 2. Its curvature is adapted to the circumferential surface of the roller 2, providing stable support and guidance for the roller 2. The inner wall of the arc-shaped support block 55 is fixedly connected to a guide post 56. The guide post 56 not only plays a guiding and positioning role for the roller 2, but also shares the weight of the roller 2 to a certain extent. At the same time, during the rotation of the roller 2, it ensures the stability of the rotation center of the roller 2 and prevents it from radially deviating.

[0033] The roller 2 has symmetrically distributed slots 57 at both ends. The inner wall of the slot 57 is movably connected to the other end of the movable plug 51. This connection method not only ensures the firm connection of the roller 2 during normal operation, but also provides convenience for its disassembly.

[0034] The outer ends of the roller 2 are in contact with the inner walls of the two arc-shaped support blocks 55 respectively. The outer side of the roller 2 is provided with symmetrically distributed guide grooves 58. The guide grooves 58 are designed to cooperate with the guide post 56 to ensure the guiding accuracy of the roller 2 during installation and disassembly, and to avoid misalignment or jamming.

[0035] The inner wall of the guide groove 58 is movably connected to the outer side of the guide post 56. A first servo electric cylinder 59 is fixedly installed on one side of the support block 3. When the roller 2 rotates, the guide groove 58 and the guide post 56 provide stable rotational support for the roller 2, preventing it from shaking or jumping.

[0036] One end of the piston rod of the first servo electric cylinder 59 is fixedly connected to a U-shaped moving frame 510. The design of the U-shaped moving frame 510 fully considers the spatial layout and motion relationship of the equipment. While realizing its driving function, it avoids interference with other components. A second mounting hole 6 is opened on one side of the support block 3. The inner walls of the two second mounting holes 6 are rotatably connected to rotating rods 61 through bearings. The use of bearings reduces the friction of rotating rods 61 during rotation, enabling rotating rods 61 to rotate flexibly with a small power input, thereby improving the transmission efficiency of the equipment.

[0037] A worm gear 62 is fixedly sleeved on the outside of the rotating rod 61. The worm gear 62 and the worm 67 cooperate to form a reliable transmission structure. This transmission structure has a large transmission ratio and self-locking characteristics, and can realize precise speed reduction and torque amplification functions to meet the torque and speed requirements of the equipment at different working stages.

[0038] The two ends of the rotating rod 61 are fixedly sleeved with symmetrically distributed drive pulleys 63. The drive pulleys 63 are externally connected to a synchronous belt 64. The drive pulleys 63 and the synchronous belt 64 can be replaced with sprockets and chains according to the usage requirements.

[0039] The inner wall of the synchronous belt 64 is connected to a driven pulley 65. The inner wall of the driven pulley 65 is fixedly sleeved with the other end of the rotating sleeve 5. This connection method ensures the synchronous rotation between the driven pulley 65 and the rotating sleeve 5, accurately transmitting power from the synchronous belt 64 to the rotating sleeve 5, thereby driving the roller 2 to rotate.

[0040] A servo motor 66 is fixedly installed on the upper end of the base 1. The output shaft of the servo motor 66 is fixedly installed with a worm gear 67 through a coupling. The outer surface of the worm gear 67 meshes with the tooth surface of the worm wheel 62. This transmission method can achieve a large transmission ratio and self-locking function, ensuring the stability of the roller 2 when the equipment is stopped, and preventing it from reversing due to load.

[0041] The upper end of the base 1 is fixedly equipped with symmetrically distributed second servo electric cylinders 7. One end of the piston rod of each of the two second servo electric cylinders 7 is fixedly connected to an arc-shaped support frame 8. The lower end of the arc-shaped support frame 8 contacts the upper end of the base 1. The second servo electric cylinders 7 are mainly responsible for driving the arc-shaped support frame 8 to realize the pushing operation of the circular roller 2 and the wound geotextile. The arc-shaped support frame 8 is designed to support the geotextile and the circular roller 2 unloaded from the circular roller 2. Its arc shape matches the shape of the circular roller 2, ensuring the stability of the geotextile and the circular roller 2 during the support process.

[0042] The working process of this utility model:

[0043] Step 1: During installation, the first servo electric cylinder 59 is activated to retract. The retraction of the first servo electric cylinder 59 drives the U-shaped moving frame 510 to move, so that one end of the U-shaped moving frame 510 contacts the drive block. The drive rod 54 drives the movable insert block 51 to retract. At this time, the support spring 52 retracts. Then, the round roller 2 is inserted into the guide post 56 through the cooperation of the guide groove 58. At this time, both ends of the round roller 2 are supported by the arc-shaped support block 55. Then, the first servo electric cylinder 59 is activated to extend, thereby driving the U-shaped moving frame 510 to disengage from the drive rod 54. At this time, the elastic force of the support spring 52 drives the movable insert block 51 to reset and move into the slot 57 to limit the round roller 2.

[0044] Step 2: During winding, the servo motor 66 is started to drive the worm 67 to rotate. The rotation of the worm 67 drives the rotating rod 61 to rotate through the meshing worm wheel 62. The rotation of the rotating rod 61 drives the driven pulley 65 to rotate through the cooperation of the driving pulley 63 and the synchronous belt 64. The driven pulley 65 drives the circular roller 2 to rotate and wind up through the cooperation of the rotating sleeve 5 and the movable insert block 51.

[0045] Step 3: After winding is complete, the opening of the arc-shaped support block 55 faces downward. The retraction of the first servo electric cylinder 59 drives the U-shaped moving frame 510 to move. The drive rod 54 drives the movable insert block 51 to retract. When the movable insert block 51 disengages from the slot 57, its weight causes the roller 2 and the wound geotextile to detach from the guide post 56 and fall above the arc-shaped support frame 8. Then, the second servo electric cylinder 7 extends, thereby driving the roller 2 and the wound geotextile out of the equipment, making it easy for the operator to remove them.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
