Description

Technical Field

[0001] This invention relates to the field of lifting sling production and processing, specifically a polymer lifting sling weaving device. Background Technology

[0002] Polymer lifting slings, also known as polymer lifting slings, consist of a load-bearing inner core and a protective sleeve. They are usually circular in structure. The load-bearing inner core is often a rope woven from high-strength fibers, while the protective sleeve is made of fabric or a woven strip structure to protect the load-bearing inner core from friction.

[0003] Currently, when weaving load-bearing inner cores, high-strength fibers are often wound regularly using a weaving device. However, due to the large size of the existing winding rollers for high-strength fiber weaving, the length and position of the high-strength fibers change during the actual feeding process, causing them to loosen and become unstretched. This affects the tightness of the weaving and the quality of the weaving. Summary of the Invention

[0004] The purpose of this invention is to provide a polymer sling weaving device to solve the problem that existing winding rollers for high-strength fiber weaving are too large, often resulting in the high-strength fibers being in an unstretched state during actual fiber feeding, thus affecting the weaving tightness.

[0005] To achieve the above objectives, the present invention provides a polymer suspender weaving device, including a processing table on which a rotating base is mounted. The rotating base is driven to rotate by a rotating assembly on the processing table. Multiple sets of yarn feeding structures are evenly installed along the circumferential direction on the rotating base. Each yarn feeding structure includes a supporting base plate and a supporting top plate. The supporting base plate is fixedly mounted on the rotating base, and the supporting top plate is positioned above the supporting base plate and is lifted by a lifting assembly. A rotary fixture for fixing the yarn feeding roller is coaxially and damped at the near ends of the supporting base plate and the supporting top plate. A set of fixed rails is installed on each side of the supporting base plate. A first lifting slider and a second lifting slider are slidably mounted within each of the two sets of fixed rails. The first and second lifting sliders form a helical transmission pair with the lifting screws within their respective fixed rails. The lifting screws are connected to the power assembly on the support top plate via a transmission rod. The power assembly drives the two lifting screws to rotate synchronously. A clamping assembly is installed on the side of the first lifting slider near the wire feeding roller. The clamping assembly includes a clamping block, which is elastically installed on the side of the first lifting slider near the wire feeding roller and clamps the surface of the wire feeding roller. A wire guide assembly is installed on the second lifting slider. The wire guide assembly includes a mounting block and two sets of wire guide wheels. Two sets of drive sliders are slidably installed on the mounting block. The two sets of wire guide wheels are rotatably installed on the corresponding drive sliders. The mounting block has a guide groove for the two sets of drive sliders to slide. Two sets of first elastic members are provided in the guide groove. The two sets of first elastic members support the two sets of drive sliders to slide in opposite directions. An auxiliary guide wheel and a wire guide tube are installed on the support top plate.

[0006] As a further embodiment of the present invention, the rotating assembly includes a drive shaft and a first power motor. The drive shaft is coaxially fixedly installed at the bottom of the rotating base, and the first power motor is fixedly installed at the bottom of the processing table and is connected to the drive shaft through a gear assembly.

[0007] As a further embodiment of the present invention, the lifting assembly includes two sets of lifting rods and two sets of guide tubes. The two sets of guide tubes are fixedly installed on the support base plate, and fixed nuts are fixedly installed at their upper ends. External threaded columns are installed at the bottom of the two sets of lifting rods. The two sets of external threaded columns and the corresponding fixed nuts form a helical transmission. The upper ends of the two sets of lifting rods are rotatably connected to the support top plate, and the upper ends of the two sets of lifting rods are connected by a first transmission belt. The upper end of one set of lifting rods is connected to the output shaft of the second power motor.

[0008] As a further embodiment of the present invention, two sets of guide frames are installed at the bottom of the supporting top plate, and the two sets of guide frames are slidably connected to the upper end of the corresponding fixed track.

[0009] As a further embodiment of the present invention, the tops of the two sets of lifting screws extend out of the fixed rails, and a set of transmission sleeves is slidably installed on the top of the lifting screws. The transmission sleeves are limited to slide along the axial direction of the lifting screws. The two sets of transmission sleeves are connected by a second transmission belt, and one set of transmission sleeves is connected by a coupling to a third power motor installed on the support top plate.

[0010] As a further embodiment of the present invention, the number of clamping blocks is two sets, the contact end of the clamping block with the wire feeding roller is provided with an arc-shaped surface, and multiple sets of guide rods 8083 are fixedly installed at the other end of the clamping block. The multiple sets of guide rods 8083 are slidably connected to the fixed plate installed at the end of the first lifting slider, and a second helical spring that is elastically connected to the fixed plate is wound around the outside of the guide rod 8083.

[0011] As a further embodiment of the present invention, the two sets of guide wheels are arranged vertically, the first elastic element is a first spring, the two sets of first springs are fixedly installed in the guide groove and elastically connected to the corresponding drive slider, and a partition for connecting the two sets of first springs is provided in the middle of the guide groove.

[0012] As a further embodiment of the present invention, the auxiliary guide wheel is disposed on the lower side of the guide tube, and an anti-wear rubber ring is installed inside the guide tube.

[0013] Compared with existing technologies, this invention designs a processing table on which a rotating base and multiple sets of yarn feeding structures are installed. The yarn feeding structures include a first lifting slider and a second lifting slider. A clamping assembly, comprising a clamping block, is installed on one side of the first lifting slider. The second lifting slider is equipped with a yarn guiding assembly, comprising a mounting block and two sets of guide wheels. This invention uses an elastically configured clamping block to clamp the yarn wound around the outside of the yarn feeding roller. Simultaneously, the two sets of guide wheels assist in guiding and conveying the high-strength fiber yarn while straightening it. This solves the problem that existing high-strength fiber weaving rollers are large in size, causing the high-strength fiber to slacken and become unstretched during the actual yarn feeding process due to changes in the length and position of the fiber, thus affecting the weaving tightness and quality.

Detailed Implementation

[0021] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1 , Figure 2 , Figure 4 as well as Figure 6As shown in this embodiment of the invention, a polymer suspender weaving device includes a processing table 1 on which a rotating base 2 is mounted. The rotating base 2 is driven to rotate by a rotating assembly on the processing table 1. Multiple sets of yarn feeding structures 8 are evenly installed on the rotating base 2 along its circumferential direction. Each yarn feeding structure 8 includes a supporting base plate 801 and a supporting top plate 802. The supporting base plate 801 is fixedly installed on the rotating base 2, and the supporting top plate 802 is located on the upper side of the supporting base plate 801 and is driven to rise and fall by a lifting assembly 804. A rotary fixture 803 for fixing the yarn feeding roller 5 is coaxially damped and rotatably mounted near the supporting base plate and the supporting top plate 802. A set of fixed rails 805 are respectively installed on both sides of the supporting base plate. A first lifting slider 806 and a second lifting slider 807 are slidably installed in the two sets of fixed rails 805. The first lifting slider 806 and the second lifting slider 807 are respectively connected to the lifting screw 815 in the corresponding fixed rail 805. A helical transmission is formed, and the two sets of lifting screws 815 are connected to the power component on the support top plate 802 through transmission rods. The power component drives the two sets of lifting screws 815 to rotate synchronously. A pressing component 808 is installed on the side of the first lifting slider near the wire feeding roller 5. The pressing component 808 includes a pressing block 8081. The pressing block 8081 is elastically installed on the side of the first lifting slider near the wire feeding roller 5 and presses the surface of the wire feeding roller 5. A wire guide component is installed on the second lifting slider. The wire guide component includes a mounting block and two sets of wire guide wheels. Two sets of driving sliders are slidably installed on the mounting block. The two sets of wire guide wheels are rotatably installed on the corresponding driving sliders. The mounting block is provided with a guide groove for the two sets of driving sliders to slide. Two sets of first elastic members are provided in the guide groove. The two sets of first elastic members support the two sets of driving sliders to slide in opposite directions. An auxiliary guide wheel 816 and a wire guide tube 817 are installed on the support top plate 802.

[0023] Specifically, when operating this invention, the first step is to place the feeding roller 5 inside the feeding structure 8. During installation, the lifting assembly 804 can drive the supporting top plate 802 to move upward to make room. At this time, the operator can fix the feeding roller 5 on the rotary fixture 803 on the supporting bottom plate 801, and the lifting assembly 804 can drive the supporting top plate 802 to descend and reset. The rotary fixture 803 at the bottom of the supporting top plate 802 presses the upper end of the feeding roller 5. After the feeding roller 5 is placed, the end of the high-strength fiber 6 on the feeding roller 5 can be inserted through the two sets of guide wheels of the guide assembly, and wound around the auxiliary guide wheel 816 along the guide of the two sets of guide wheels, and then passed out through the guide tube 817 and conveyed upward.

[0024] During the weaving process, the rotating base 2 is rotated by the rotating assembly, and the high-strength fiber 6 is drawn out by the feeding roller 5. During the weaving process, the present invention installs the pressing assembly 808 and the guide assembly on the first lifting slider and the second lifting slider respectively. During the feeding process of the high-strength fiber 6, the first lifting slider and the second lifting slider are matched with the winding position of the high-strength fiber 6 and move back and forth in the vertical direction. The pressing block 8081 in the pressing assembly 808 presses the outer wall of the feeding roller 5 to avoid the problem of the high-strength fiber 6 winding during the winding process. The high-strength fiber 6 is elastically supported by two sets of elastically supported guide wheels in the feeding assembly, so that the high-strength fiber 6 always remains taut during the feeding process.

[0025] like Figure 1 As shown, in this embodiment of the invention, the rotating assembly includes a drive shaft 3 and a first power motor 4. The drive shaft 3 is coaxially fixedly installed at the bottom of the rotating base 2, and the first power motor 4 is fixedly installed at the bottom of the processing table 1 and is connected to the drive shaft 3 via a gear assembly. The gear assembly includes a drive gear 401 and a transmission gear ring 301. The drive gear 401 is fixedly installed on the output shaft of the first power motor 4, and the transmission gear ring 301 is coaxially installed on the outside of the drive shaft 3 and meshes with the drive gear 401 for transmission. This invention utilizes the first power motor 4 and the drive shaft 3 at the bottom of the rotating base 2 to drive the rotating base 2 to rotate synchronously. However, in actual design, other existing rotating assemblies can be designed to replace the drive shaft 3 and the first power motor 4 selected in this invention.

[0026] like Figure 3 As shown, in this embodiment of the invention, the lifting assembly 804 includes two sets of lifting rods 8041 and two sets of guide tubes 8042. The two sets of guide tubes 8042 are fixedly installed on the support base plate 801, and fixed nuts 8044 are fixedly installed at their upper ends. External threaded posts 8043 are installed at the bottom of the two sets of lifting rods 8041. The two sets of external threaded posts 8043 and the corresponding fixed nuts 8044 form a helical drive. The upper ends of the two sets of lifting rods 8041 are rotatably connected to the support top plate 802.

[0027] Furthermore, the upper ends of the two sets of lifting rods 8041 are connected by the first transmission belt 814, and the upper end of one set of lifting rods 8041 is connected to the output shaft of the second power motor 813. When the invention realizes the lifting operation of the supporting top plate 802, the two sets of lifting rods 8041 are driven to rotate synchronously by the second power motor 813. The external threaded column 8043 is connected to the corresponding fixing nut 8044 to realize the vertical lifting of the lifting rods 8041.

[0028] Meanwhile, two sets of guide frames 7 are installed at the bottom of the supporting top plate 802. The two sets of guide frames 7 are slidably connected to the upper end of the corresponding fixed track. When the supporting top plate 802 slides vertically, the slidable connection between the fixed track and the corresponding guide frame 7 improves the support strength of the fixed track.

[0029] like Figure 3 and Figure 4 As shown, in this embodiment of the invention, the tops of the two sets of lifting screws 815 extend out of the fixed rails 805, the supporting top plate 802 is provided with a connecting hole for the ends of the two sets of lifting screws 815 to extend out, and a set of transmission sleeves 811 is slidably installed on the top of the lifting screws 815. The transmission sleeves 811 are limited to slide along the axial direction of the lifting screws 815. The two sets of transmission sleeves 811 are connected by a second transmission belt 812, and one set of transmission sleeves 811 is connected by a coupling to a third power motor 810 installed on the supporting top plate 802.

[0030] In this invention, multiple sets of limiting strips 8151 are fixedly installed on the top outer side of the lifting screw 815. The corresponding transmission sleeve 811 will have a limiting groove that is slidably connected to the limiting strips 8151. When the supporting top plate 802 is raised or lowered, the transmission sleeve 811 slides in the vertical direction and is always slidably connected to the top of the lifting screw 815. The third power motor 810 drives the two sets of transmission sleeves 811 and the two sets of lifting screws 815 to rotate synchronously, so as to realize the synchronous raising and lowering of the first lifting slider and the second lifting slider.

[0031] like Figure 2 and Figure 5 As shown, in this embodiment of the invention, there are two sets of clamping blocks 8081. The contact end of the clamping block 8081 with the wire feeding roller 5 is provided with an arc-shaped surface. Multiple sets of guide rods 8083 are fixedly installed at the other end of the clamping block 8081. The multiple sets of guide rods 8083 are slidably connected to the fixed plate installed at the end of the first lifting slider. A second helical spring 8082 that is elastically connected to the fixed plate is wound around the outside of the guide rod 8083. By setting the second helical spring 8082, the clamping block 8081 is elastically connected to the first lifting slider. When the wire feeding roller 5 is feeding wire, as the thickness of the outer wall of the wire feeding roller 5 decreases, the clamping block always remains pressed against the outer wall of the wire feeding roller 5.

[0032] like Figure 2 and Figure 6As shown, in this embodiment of the invention, two sets of guide wheels are arranged vertically, and the first elastic element is a first spring 8093. The two sets of first springs 8093 are fixedly installed in the guide groove and elastically connected to the corresponding drive slider. A partition plate 8094 for connecting the two sets of first springs 8093 is provided in the middle of the guide groove. The invention uses guide wheels that are arranged vertically and elastically connected to straighten and support the high-strength fiber 6 during the feeding process, so as to avoid the high-strength fiber 6 from becoming loose when its length and position change during the feeding operation.

[0033] like Figure 2 As shown, in this embodiment of the invention, the auxiliary guide wheel 816 is disposed on the lower side of the guide tube 817, and an anti-abrasion rubber ring is installed inside the guide tube 817. The auxiliary guide wheel 816 cooperates with the guide wheel to guide the yarn feeding. At the same time, the anti-abrasion rubber ring inside the guide tube 817 can protect the surface of the high-strength fiber 6 and prevent it from being damaged or scratched.

[0034] In summary, this invention designs a processing table 1 on which a rotating base 2 and multiple sets of yarn feeding structures 8 are installed. Each yarn feeding structure 8 contains a first lifting slider 806 and a second lifting slider 807. A pressing component 808, including a pressing block 8081, is installed on one side of the first lifting slider. A yarn guide component, including a mounting block and two sets of guide wheels, is installed on the second lifting slider. This invention uses the elastically set pressing block 8081 to press the yarn wound around the outside of the yarn feeding roller 5. Simultaneously, the two sets of guide wheels assist in guiding and conveying the high-strength fiber 6 while straightening the yarn. This solves the problem that existing winding rollers for high-strength fiber 6 are too large, causing the high-strength fiber 6 to become loose and unstretched during the actual yarn feeding process due to changes in its length and position, thus affecting the weaving tightness and quality.

[0035] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
