Description

Technical Field

[0001] This utility model relates to the field of pre-spinning nylon production technology, and in particular to an auxiliary platform vehicle for a recycled polyamide 6 winding device. Background Technology

[0002] Regenerated polyamide 6 refers to waste polyamide 6 that has been subjected to alcoholysis with alkyd monomers under specific temperature and pressure conditions to generate alcoholyzed polyamide 6 segments with carboxyl and amino groups at both ends. These segments are then subjected to esterification and amidation reactions under specific conditions to prepare recycled polyamide 6, which is then melt-spun into coarse fibers. After the fibers are cooled and shaped, they are oiled and then wound in a winding machine.

[0003] Existing recycled polyamide 6 winding machines include at least a guide device and a winding device for winding the filaments. Furthermore, these machines are divided into upper and lower layers, with the guide device on the upper layer and the winding device on the lower layer. After the winding device is fully wound and unwound, the operator needs to clean both the winding device and the guide device. Because the winding machine is divided into upper and lower layers, an auxiliary platform cart is required for cleaning, allowing the operator to clean the guide device located on the upper layer. Existing auxiliary platform carts include... Figure 1 As shown, the system includes a platform 10, with a staircase 20 on one side for operators to climb. A frame structure is located at the bottom of the platform, creating a gap between the platform and the ground. The platform is 1.3 meters above the ground, allowing operators to perform hot roller and yarn path cleaning operations on the guide device located on the upper layer of the winding machine when positioned on the platform. The frame structure includes a bottom frame 30, side frames 40, and a central support 50. The side frames are connected to the other side of the platform, and the upper end of the central support is connected to the platform, while its lower end is connected to the bottom frame.

[0004] The bottom frame is connected to feet 60 and a caster mechanism 70, which can swing relative to the bottom frame. For cleaning, the caster mechanism is retracted, at which point the feet are in contact with the ground. For moving, the caster mechanism is lowered, at which point the feet are separated from the ground.

[0005] However, the existing auxiliary platform carts have limited space under the platform due to the design of the bottom frame, middle support and caster mechanism. This makes it difficult for multiple people to operate at the same time, and it is inconvenient to carry out full roll unwinding and hot roller and yarn path hygiene cleaning at the same time. This results in increased waste yarn consumption, long machine downtime and increased production costs. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an auxiliary platform cart for a recycled polyamide 6 winding device, which can increase the space under the platform to facilitate multiple people to perform full roll unwinding, hot roller and yarn path hygiene cleaning operations at the same time.

[0007] This utility model is implemented as follows:

[0008] This utility model provides an auxiliary platform vehicle for a recycled polyamide 6 winding device, including a standing platform for the operator to stand on and a ladder for the operator to climb. The ladder is connected to one side of the standing platform at an incline, and a support frame is connected to the other side of the standing platform. The support frame and the ladder together support the standing platform so that the height of the top of the standing platform matches the height of the second layer of the winding machine, and there is an accommodation space under the standing platform for the operator to enter.

[0009] The platform vehicle also includes an inclined reinforcing rod, one end of which is connected to the support frame and the other end of which is connected to the standing platform.

[0010] Furthermore, the bottom of the ladder and the bottom of the support frame are equipped with swivel casters with foot brakes.

[0011] Furthermore, a guardrail is also provided on the top of the standing platform. The guardrail is divided into a first guardrail and a second guardrail. The first guardrail is located on the side of the standing platform away from the winding machine, and the second guardrail is located on the side of the standing platform closer to the support frame.

[0012] Furthermore, the standing platform includes two first longitudinal tubes arranged opposite each other, the lengths of the two first longitudinal tubes matching the length of the standing platform. The standing platform also includes a patterned plate and a plurality of first transverse tubes, each of which is arranged between the two first longitudinal tubes. The first transverse tubes and the first longitudinal tubes form a standing frame structure. The patterned plate is arranged on the top of the standing frame structure, and the upper end of the reinforcing rod is connected to the first longitudinal tube.

[0013] Furthermore, the ladder includes two sets of oppositely arranged footplate support pipes, a plurality of footplates, two vertical pipes, a second horizontal pipe, and two second longitudinal pipes matching the length of the footplates. The footplates are connected between the two sets of footplate support pipes. Each set of footplate support pipes includes a first connecting pipe and a second connecting pipe. The first connecting pipe is connected to the end of the first longitudinal pipe, and the second connecting pipe is located on the side of the first connecting pipe near the support frame. The lower end of the first connecting pipe is fixedly connected to the vertical pipe. The second horizontal pipe is connected between the two vertical pipes. The second longitudinal pipe is connected to the side of the vertical pipe near the support frame, and the length of the second longitudinal pipe matches the length of the footplate. The upper end of the second connecting pipe is connected to the first longitudinal pipe, and the lower end of the second connecting pipe is connected to the second longitudinal pipe.

[0014] Furthermore, each of the aforementioned pedals is also welded with reinforcing steel bars for anti-slip purposes.

[0015] The advantages of this utility model are as follows: by replacing the central support in the prior art with an inclined reinforcing rod, and by setting the universal casters at the bottom of the ladder and support frame, the space under the standing platform is increased, making it easier for operators to enter the space under the standing platform. This allows multiple people to simultaneously perform full roll unwinding, hot roller and yarn path cleaning operations, reducing machine downtime of the winding device, shortening the head lifting time by 5 minutes, and saving 160 kg / day of waste yarn consumption, which greatly saves production costs and improves the product AA rate.

[0024] Please see Figures 1 to 5This utility model provides an auxiliary platform vehicle for a recycled polyamide 6 winding device, including a standing platform 1 for the operator to stand on and a ladder 2 for the operator to climb. The ladder 2 is inclined and connected to one side of the standing platform 1. A support frame 3 is connected to the other side of the standing platform 1. The support frame 3 and the ladder 2 together support the standing platform 1. The standing platform 1 is 1.3 meters above the ground, 1.2 meters long, and 685 mm wide, so that the height of the top of the standing platform 1 matches the height of the second layer of the winding machine. The standing platform 1 has a space 4 for the operator to enter below it. The bottom of the ladder 2 and the bottom of the support frame 3 are equipped with omnidirectional casters 5 with foot brakes.

[0025] The platform vehicle also includes an inclined reinforcing rod 6, one end of which is connected to the support frame 3, and the other end of which is connected to the standing platform 1. Figure 2 As shown, the upper end of the reinforcing rod 6 is connected to the right side of the center line of the standing platform 1, and the distance L between the upper end of the reinforcing rod 6 and the right end face of the standing platform 1 is 1 / 3 to 1 / 4 of the total length of the standing platform 1.

[0026] Specifically, the top of the standing platform 1 is also provided with a guardrail 7, which is divided into a first guardrail 7 and a second guardrail 7. The first guardrail 7 is located on the side of the standing platform 1 away from the winding machine, and the second guardrail 7 is located on the side of the standing platform 1 close to the support frame 3.

[0027] Specifically, the standing platform 1 includes two opposing first longitudinal tubes 11, the length of which matches the length of the standing platform 1. The standing platform 1 also includes a patterned plate 12 and a plurality of first transverse tubes 13, each of which is positioned between the two first longitudinal tubes 11. The first transverse tubes 13 and the first longitudinal tubes 11 form a standing frame structure. The patterned plate 12 is positioned at the top of the standing frame structure, and the upper end of the reinforcing rod 6 is connected to the first longitudinal tubes 11. The patterned plate 12 improves the anti-slip properties of the surface of the standing platform 1.

[0028] Specifically, the ladder 2 includes two sets of opposing footplate support pipes 21, a plurality of footplates 22, two vertical pipes 23, a second horizontal pipe 24, and two second longitudinal pipes 25 matching the length of the footplates 22. The footplates 22 are connected between the two sets of footplate support pipes 21. Each set of footplate support pipes 21 includes a first connecting pipe 211 and a second connecting pipe 212. The same side of each footplate 22 is fixedly connected to the corresponding first connecting pipe 211 and second connecting pipe 212. The first connecting pipe 211 is connected to the first longitudinal pipe 11. The second connecting pipe 212 is located at the end of the first connecting pipe 211 near the support frame 3. The lower end of the first connecting pipe 211 is fixedly connected to the vertical pipe 23. The second transverse pipe 24 is connected between the two vertical pipes 23. The second longitudinal pipe 25 is connected to the vertical pipe 23 near the support frame 3, and the length of the second longitudinal pipe 25 matches the length of the pedal 22. The upper end of the second connecting pipe 212 is connected to the first longitudinal pipe 11, and the lower end of the second connecting pipe 212 is connected to the second longitudinal pipe 25. After the second connecting pipe 212 is connected to the first longitudinal pipe 11 and the second longitudinal pipe 25, and cooperates with the reinforcing rod 6, it can increase the strength of the standing platform 1, so that the standing platform 1 can still maintain sufficient strength after the central support in the prior art is removed. The omnidirectional caster 5 is connected to the second longitudinal pipe 25.

[0029] Specifically, each of the aforementioned pedals 22 is also welded with a reinforcing steel strip 26 for anti-slip purposes. The reinforcing steel strip 26 is located on the outer side of the pedal, and when the operator steps on the pedal, the reinforcing steel strip 26 is located at the operator's heel.

[0030] By replacing the central support in the prior art with an inclined reinforcing rod 6, and with omnidirectional casters 5 installed at the bottom of the ladder 2 and support frame 3, the space under the standing platform 1 is increased, making it easier for operators to enter the space under the standing platform 1. This allows multiple people to simultaneously perform full-winding and hot roller cleaning and yarn path cleaning operations, reducing machine downtime of the winding device, shortening the head lifting time by 5 minutes, and saving 160 kg / day of waste yarn consumption, greatly saving production costs and improving the product AA rate.

[0031] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
