Description

Technical Field

[0001] This invention relates to the field of chemical fiber rope processing, specifically a chemical fiber rope sanding device. Background Technology

[0002] Currently, most commercially available synthetic fiber rope sanding devices have a relatively simple structure, employing a single-unit sanding structure to directly perform open-type sanding operations on the synthetic fiber rope. Such equipment has numerous shortcomings in actual processing.

[0003] Firstly, the grinding structure is mostly set up in a single group, which limits the grinding coverage and results in poor uniformity of the grinding. This can easily lead to over-grinding or under-grinding in some areas, resulting in low product processing precision and difficulty in ensuring the yield rate.

[0004] Secondly, most existing sanding equipment has an open working structure, which generates a large amount of chemical fiber shavings and dust impurities during the sanding process. These fine debris can easily spread directly into the processing environment, causing pollution to the workshop environment, affecting the cleanliness of the workshop working environment, and endangering the health of the operators. At the same time, the accumulation of scattered shavings also poses certain fire safety hazards. Summary of the Invention

[0005] The purpose of this invention is to provide a synthetic fiber rope abrasion device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A synthetic fiber rope abrasion device includes a base and a lower housing fixed above the base. A motor is fixedly connected above the base. An upper housing is rotatably connected above the lower housing. A drive shaft and a driven shaft are rotatably connected to the lower housing. The drive shaft and the driven shaft are connected by a transmission connection, and the drive shaft is also connected by a transmission connection to the output shaft of the motor. Two sets of abrasion components are fixedly connected to the outer sides of both the drive shaft and the driven shaft. Guide wheel assemblies are fixedly connected to the inner sides of the upper housing and the lower housing. The side wall of the lower housing has a rope inlet hole and a rope outlet hole. After passing through the rope inlet hole, the synthetic fiber rope passes around the outer sides of different abrasion components in sequence and then exits through the rope outlet hole to the outer side of the lower housing.

[0007] As a further aspect of the present invention, it also includes a constant tension winding assembly, wherein the chemical fiber rope passing through the rope outlet hole is fixedly connected to the winding wheel of the constant tension winding assembly.

[0008] As a further embodiment of the present invention: the base includes a fixed seat and a shock-absorbing plate, a shock-absorbing layer is fixedly connected between the fixed seat and the shock-absorbing plate, and supports are fixedly connected to the four corners of the bottom of the fixed seat.

[0009] As a further embodiment of the present invention: a bearing seat is fixedly connected to the outer wall of the lower housing, and both the driving shaft and the driven shaft are rotatably connected to the bearing seat. The driving shaft and the driven shaft are connected by a pulley drive, and the pulleys connected to the ends of the driving shaft and the driven shaft have the same diameter.

[0010] As a further embodiment of the present invention: the abrasive assembly includes a polishing wheel fixedly connected to the drive shaft or the driven shaft. The polishing wheel is a grooved wheel, and the chemical fiber rope contacts the bottom and side of the groove of the polishing wheel when it comes into contact with the polishing wheel.

[0011] As a further embodiment of the present invention: reinforcing rings are fixedly connected to the outer sides of both the rope inlet and the rope outlet.

[0012] As a further embodiment of the present invention: the top of the upper box is provided with a manhole for operating the chemical fiber rope, and a cover plate is provided on the outside of the manhole.

[0013] As a further embodiment of the present invention: a liquid pump is fixedly connected to the upper housing, the liquid pump inlet pipe passes through the upper housing and its end extends into the lower housing, the liquid pump outlet pipe passes through the upper housing and is connected to a spray pipe, the spray pipe is arranged parallel to the driven shaft, and the spray pipe is located above the abrasion assembly.

[0014] As a further embodiment of the present invention: a purification box is fixedly connected to the top of the upper box, and the two sides of the purification box are connected to the inside of the upper box through purification pipes. A fan is fixedly connected inside the purification box, and filter elements are fixedly connected to both sides of the fan.

[0015] As a further embodiment of the present invention: the guide wheel assembly includes a first guide wheel fixedly connected inside the upper housing, a screw rotatably connected to the side wall of the lower housing, a wheel frame threadedly connected to the outside of the screw, the wheel frame being slidably connected to the lower housing, and a second guide wheel and a third guide wheel fixedly connected to the wheel frame for guiding. After passing through one set of abrasion components, the chemical fiber rope passes through the first guide wheel, the second guide wheel and the third guide wheel in sequence and then enters another set of abrasion components.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention drives the active shaft and the driven shaft to rotate synchronously by a motor, which in turn drives the four sets of grinding components set on the outside of the active shaft and the driven shaft to rotate synchronously for grinding. The device uses guide wheels to realize reversal inside the box, thereby confining the entire grinding process inside the box. In conjunction with the purification box set on the outside of the box, it effectively avoids the scattering of lint during the grinding process and ensures the environmental quality of the grinding process.

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Please refer to the attached diagram. A synthetic fiber rope sanding device is based on a base 1 as its support, with all core working structures mounted on top of the base 1, resulting in a stable structure. A lower housing 2 is fixedly installed on top of the base 1, serving as the main processing chamber of the device. A motor 3 is also fixedly mounted on the top surface of the base 1, acting as the core power source for the entire device and providing continuous power for the sanding operation.

[0030] The upper housing 4 is rotatably mounted on the top of the lower housing 2. The upper and lower housings cooperate to form a closed processing space, which not only prevents dust from spilling out during the sanding process, but also protects the internal transmission and sanding structures, reducing production losses. To complete the sanding process of the chemical fiber rope, the lower housing 2 is equipped with a drive shaft 5 and a driven shaft 6, which are parallel to each other and work together. The drive shaft 5 is connected to the output shaft of the motor 3 and is directly driven by the motor 3. At the same time, the drive shaft 5 and the driven shaft 6 are also connected by a transmission structure, which can realize single-power dual-shaft synchronous operation, reduce equipment energy consumption, and simplify the transmission structure.

[0031] To ensure the stability of the operation of the drive shaft 5 and driven shaft 6, a bearing seat 13 is fixedly mounted on the outer wall of the lower housing 2. Both ends of the drive shaft 5 and driven shaft 6 are rotatably engaged with the bearing seat 13, limiting the shaking and offset of the shafts during operation. In terms of transmission configuration, pulleys are installed at the ends of both the drive shaft 5 and driven shaft 6, and the diameters of the two sets of pulleys are exactly the same. Belt drive ensures that the rotational speeds of the two shafts are completely synchronized, resulting in a uniform and consistent grinding operation and improving product processing consistency. To prevent belt slack from affecting the transmission effect, a tensioning pulley can also be installed as needed to ensure transmission efficiency.

[0032] Two sets of sanding components 7 are fixedly installed on the outer sides of both the drive shaft 5 and the driven shaft 6. These are the core components that directly complete the sanding process of the synthetic fiber rope, rotating synchronously with the shaft to perform the sanding operation. Specifically, the main body of the sanding component 7 includes a sanding wheel 14, which is directly fixed on the drive shaft 5 or the driven shaft 6 and rotates synchronously with the shaft. The sanding wheel 14 adopts a grooved wheel structure, which is adapted to the sanding requirements of synthetic fiber ropes. The synthetic fiber rope is placed close to the groove of the sanding wheel 14, and during sanding, the rope can simultaneously and fully contact the bottom and both sides of the groove, enabling all-round sanding of the rope surface, avoiding localized incomplete sanding, improving the uniformity of sanding, and meeting the processing standards for mass production.

[0033] To ensure the synthetic fiber rope maintains a regular and unbiased trajectory during processing, guide wheel assemblies 8 are uniformly installed inside both the upper and lower housings. Multiple guide wheels work together to change the direction and limit the rope's movement. The guide wheel assembly 8 consists of two parts: a first guide wheel 23 is fixedly installed inside the upper housing 4, serving as an upper limit guide; a screw 24 is rotatably mounted on the side wall of the lower housing 2, and a wheel frame 25 is threaded onto the outside of the screw 24, maintaining a sliding fit with the lower housing 2. Rotating the screw 24 causes the wheel frame 25 to slide up and down, allowing for fine-tuning of the guide height according to the specifications of the synthetic fiber rope and the grinding requirements, thereby adjusting the angle at which the synthetic fiber rope enters the grinding assembly 7 after changing direction. The wheel frame 25 is fixedly equipped with a second guide wheel 26 and a third guide wheel 27. After the chemical fiber rope is polished by the single-sided polishing component 7, it will pass around the first guide wheel 23, the second guide wheel 26 and the third guide wheel 27 in sequence to complete the reversal. Then it will smoothly enter the polishing component 7 on the other side for secondary polishing, realizing cyclic polishing and improving the polishing effect. The chemical fiber rope alternately passes through multiple sets of polishing wheels 14, so that the polishing wheel 14 can be fully and thoroughly polished during rotation, reducing dead angles and ensuring the polishing effect.

[0034] The lower housing 2 has rope inlet and outlet holes on its side walls, serving as channels for the chemical fiber rope to enter and exit the processing chamber. To prevent wear and deformation of the holes due to repeated friction during long-term rope threading and sanding operations, which would affect processing accuracy, reinforcing rings 15 are installed and fixed on the outer sides of both the rope inlet and outlet holes. The reinforcing rings 15 are connected to the rope inlet and outlet holes by threaded connection or snap-fit. When the reinforcing rings 15 are worn excessively, they can be replaced, effectively improving the structural strength of the holes, extending the service life of the equipment, and reducing the equipment failure rate. In actual operation, the chemical fiber rope enters the equipment through the rope inlet hole, is guided by the guide wheel assembly 8, and sequentially passes around the outer sides of each sanding assembly 7 to complete all-round sanding processing, finally exiting the equipment through the rope outlet hole.

[0035] Taking the attached diagram as an example, after passing through the rope inlet hole, the synthetic fiber rope passes under the grinding wheel 14 on the rear side of the driven shaft 6, then passes over the grinding wheel 14 on the rear side of the drive shaft 5, then passes over the first guide wheel 23, the second guide wheel 26 and the third guide wheel 27, then passes under the grinding wheel 14 on the front side of the drive shaft 5, and finally passes over the grinding wheel 14 on the front side of the driven shaft 6 before being led out through the rope outlet hole.

[0036] The equipment is also equipped with a constant tension winding assembly, where the end of the synthetic fiber rope passing through the rope outlet hole is fixedly connected to the winding wheel of the constant tension winding assembly. In actual production, the constant tension winding assembly can maintain a constant tension in the synthetic fiber rope during the sanding process, avoiding uneven sanding due to excessive looseness or stretching deformation due to excessive tightness, thus ensuring the stability of the sanding process. It also enables automatic winding after sanding, making it suitable for continuous production lines. Existing constant tension winding assemblies can be used, including but not limited to those that directly use a winding motor to drive the winding wheel for winding, thereby moving the synthetic fiber rope. The winding motor is a servo motor, effectively controlling the rotation speed. Combined with a tensioning wheel, constant tension control can be achieved. Constant tension control during the winding process is a conventional technique in this field and will not be elaborated upon here.

[0037] To improve the overall vibration damping performance of the equipment, reduce vibration noise during production, and prevent vibration from affecting grinding accuracy, the base 1 adopts a split vibration damping structure, specifically including a fixed base 9 and a vibration damping plate 10. A vibration damping layer 11 is fixedly filled between the fixed base 9 and the vibration damping plate 10, which can effectively buffer the vibration generated by motor operation and shaft rotation. At the same time, supports 12 are fixedly installed at the four corners of the bottom of the fixed base 9 to support the entire equipment, ensure that the equipment is placed stably, and further improve operational stability.

[0038] To facilitate rope threading and internal structure inspection by operators, a manhole 16 is provided on the top of the upper housing 4, with an openable cover plate on the outside of the manhole 16. During normal production, the cover plate is closed to ensure the airtightness of the cavity; during equipment debugging, rope threading, or routine maintenance, the cover plate can be opened to facilitate operation through the manhole 16 without disassembling the housing, greatly reducing the difficulty of equipment operation and maintenance.

[0039] To address the issues of dust, static electricity, and surface debris generated during the abrasion process of synthetic fiber ropes, the equipment is equipped with a spray dust removal auxiliary structure. A liquid pump 17 is fixedly installed on the upper housing 4. The inlet pipe of the liquid pump 17 passes through the upper housing 4, with its end extending into the lower housing 2, allowing it to draw liquid stored inside the housing or connect to external cleaning fluid. The outlet pipe of the liquid pump 17 also passes through the upper housing 4 and is connected to a spray pipe 18. The spray pipe 18 is arranged parallel to the driven shaft 6 and positioned directly above the abrasion assembly 7. During operation, it can evenly spray cleaning fluid downwards, promptly flushing away debris generated during abrasion, inhibiting dust diffusion, and eliminating static electricity generated during rope abrasion, thus improving production safety. The liquid pump 17 can be a peristaltic pump, jet pump, or other types of pump. A filter structure can be fixed at the end of the inlet pipe of the liquid pump 17 to prevent clogging.

[0040] To further optimize the equipment's production environment and achieve centralized dust purification, a purification box 19 is fixedly installed on top of the upper housing 4. The two sides of the purification box 19 are connected to the internal cavity of the upper housing 4 via purification pipes 20, forming a sealed dust purification channel. A fan 21 is fixedly installed inside the purification box 19, and filter elements 22 are fixedly installed on both sides of the fan 21. During equipment operation, the fan 21 generates negative pressure, drawing dust and debris generated during grinding inside the housing into the purification box 19 through the purification pipes 20. After being filtered and purified by the filter elements 22 on both sides, clean air is discharged, effectively improving the workshop production environment and meeting the factory's environmental protection production requirements.
