Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, and specifically relates to a high-temperature and high-pressure dyeing machine. Background Technology

[0002] High-temperature and high-pressure dyeing machines are mainly used for high-temperature dyeing and post-washing treatment of polyester and its blended yarns. They can also be used for dyeing cotton, acrylic, wool and other yarns. The main components are dyeing tank, liquid preparation tank, feeding pump, circulation pump, pipeline system and control box.

[0003] For example, Chinese patent literature discloses a high-temperature and high-pressure dyeing machine [Application No.: 202323622064.9; Authorization Announcement No.: CN221988853U], which includes a mixing tank, a side door on the side wall of the mixing tank, a guide pipe on the mixing tank, a motor fixedly installed on the mixing tank, a rotating rod fixedly connected to the output end of the motor, a stirring rod fixedly sleeved on the outer wall of the rotating rod, a stirring mechanism inside the stirring rod, a bearing spring fixedly installed on the inner wall of the stirring rod, a gravity ball fixedly installed at the end of the bearing spring, the gravity ball being located inside the stirring rod, and an inclined block fixedly installed on the outer wall of the gravity ball.

[0004] The aforementioned high-temperature and high-pressure dyeing machine uses the centrifugal force generated by the rotation of the gravity ball in the stirring mechanism to push the inclined block to the left and squeeze the bottom of the support plate. This causes the support plate to move the support rod upward. The extension and retraction of the support rod prevents the internal product from rotating in a circular motion with the stirring rod, thus accelerating the coloring process. However, during use, the dyeing machine is opened and closed through a side door. In actual use, the side door has poor sealing, and the dye inside the dyeing machine can easily leak out between the side door and the machine's casing, causing not only waste of dye but also environmental pollution. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a high-temperature, high-pressure dyeing machine that opens from the top.

[0006] The objective of this utility model can be achieved through the following technical solution: A high-temperature and high-pressure dyeing machine includes an outer cylinder. A shielding component is installed on the top and outside of the outer cylinder. Several support legs are connected to the bottom of the outer cylinder. A rotating groove is opened on the outer side of the bottom of the inner wall of the outer cylinder. A support ring is movably connected to the inner wall of the rotating groove through a sealed bearing. A dyeing cylinder is connected to the top of the support ring. A sealing ring is connected to the top of the inner wall of the outer cylinder. The inner wall of the sealing ring is movably connected to the top of the outer wall of the dyeing cylinder through a sealed bearing. The shielding component includes a connecting arc plate. The inner wall of the connecting arc plate is connected to the top of the outer wall of the outer cylinder. A variable frequency drive motor is connected to the bottom of the connecting arc plate. A filling component is installed at the bottom of the outer cylinder. The filling component includes a filling pipe. The top of the filling pipe passes through the outer cylinder and the dyeing cylinder and is connected to a spray pipe. Several liquid outlet holes are opened on the outside of the spray pipe and the outside of the filling pipe.

[0007] This high-temperature, high-pressure dyeing machine, through the use of shielding components, has the advantage of preventing dye leakage. The telescopic end of the electric telescopic column extends, causing it to lift the lifting plate, shielding plate, and limiting ring. Then, the variable frequency drive motor runs, causing the electric telescopic column and its top components to rotate together. This detaches the shielding plate and limiting ring from the top of the outer cylinder, exposing the dyeing cylinder. The yarn to be dyed is then placed into the dyeing cylinder, and the components are then reset sequentially. During subsequent dyeing, no dye will leak out, protecting the environment.

[0008] In the aforementioned high-temperature, high-pressure dyeing machine, the output end of the variable frequency drive motor is connected through an arc plate and to an electric telescopic column. A vacuum chamber exists between the inner wall of the outer cylinder and the outside of the dyeing cylinder. Several suction pipes are connected to the bottom of the outer cylinder, and a converging ring is connected to the side of each suction pipe furthest from the outer cylinder. The electric telescopic column, when extended at its telescopic end, drives the lifting plate and the shielding plate to rise, thereby opening the dyeing cylinder.

[0009] In the aforementioned high-temperature, high-pressure dyeing machine, an air supply pipe is connected to the outside of the converging ring. The side of the air supply pipe away from the converging ring is connected to an external vacuum pump via a flange. The external vacuum pump, when activated, can remove air from the vacuum chamber, preventing large-scale heat loss from the dyeing cylinder to the external environment.

[0010] In the aforementioned high-temperature, high-pressure dyeing machine, a lifting plate is connected to the top of the telescopic end of the electric telescopic column. A cover plate is connected to one end of the lifting plate. The cover plate is placed on top of the outer cylinder. A limiting ring is connected to the outer side of the bottom of the cover plate. The inner wall of the limiting ring slides in contact with the top of the outer cylinder. A pressure gauge is installed on the top of the cover plate. The limiting ring limits the cover plate, preventing it from moving arbitrarily on top of the outer cylinder.

[0011] In the aforementioned high-temperature, high-pressure dyeing machine, the liquid outlet is located inside the dyeing cylinder. The outer part of the filling tube is movably connected to the outer cylinder and the dyeing cylinder via a sealed bearing. A driven gear is fixedly sleeved on the bottom of the outer part of the filling tube. A mounting plate is connected to one side of one of the support legs, and a rotary motor is connected to the top of the mounting plate. The mounting plate facilitates the installation of the rotary motor.

[0012] In the aforementioned high-temperature and high-pressure dyeing machine, a drive gear that meshes with a driven gear is fixedly sleeved on the top of the output end of the rotary motor. Connecting sleeve one and connecting sleeve two are movably sleeved from top to bottom on the outside of the filling tube, located at the bottom of the driven gear, via sealed bearings. Through the cooperation of the drive gear and the driven gear, the filling tube can be rotated when the rotary motor rotates.

[0013] In the aforementioned high-temperature, high-pressure dyeing machine, a solenoid valve is installed outside the filling tube, between connecting sleeve one and connecting sleeve two. A liquid injection tube is movably installed on the bottom of the inner wall of connecting sleeve two via a sealed bearing. The side of the liquid injection tube away from connecting sleeve two is connected to an external filling pump. A drain pipe is connected to the outside of connecting sleeve one, and a solenoid valve two is installed on the drain pipe. The side of the drain pipe away from connecting sleeve one is connected to an external drain pump. The cooperation of connecting sleeve one and connecting sleeve two facilitates the connection of the liquid injection tube and drain pipe with the filling tube.

[0014] Compared with existing technologies, this high-temperature and high-pressure dyeing machine has the advantage of preventing dye leakage through the use of shielding components. The telescopic end of the electric telescopic column extends, causing it to lift the lifting plate, shielding plate, and limiting ring. Then, the frequency converter drives the motor to rotate the electric telescopic column and the components on its top, causing the shielding plate and limiting ring to detach from the top of the outer cylinder, exposing the dyeing cylinder. The yarn to be dyed is then placed into the dyeing cylinder, and the components are then reset in sequence. During subsequent dyeing, the dye will not leak out, protecting the environment.

The inner wall of the sealing ring 8 is movably connected to the top of the outside of the dyeing cylinder 9 through a sealed bearing. The shielding component 1 includes a connecting arc plate 13. The inner wall of the connecting arc plate 13 is connected to the top of the outside of the outer cylinder 2. A variable frequency drive motor 16 is connected to the bottom of the connecting arc plate 13. A filling component 7 is installed at the bottom of the outer cylinder 2. The filling component 7 includes a filling pipe 710. The top of the filling pipe 710 passes through the outer cylinder 2 and the dyeing cylinder 9 and is connected to a spray pipe 712. Several liquid outlet holes 711 are opened on the outside of the spray pipe 712 and the outside of the filling pipe 710.

[0025] To elaborate further, the output end of the variable frequency drive motor 16 is connected through the arc plate 13 and connected to the electric telescopic column 15. The inner wall of the outer cylinder 2 and the outside of the dyeing cylinder 9 form a vacuum chamber. Several suction pipes 4 are connected to the bottom of the outer cylinder 2. The side of the suction pipes 4 away from the outer cylinder 2 is connected to a converging ring 3.

[0026] An external gas supply pipe 5 is connected to the converging ring 3. The side of the gas supply pipe 5 away from the converging ring 3 is connected to an external vacuum pump via a flange. A lifting plate 11 is connected to the top of the telescopic end of the electric telescopic column 15. A cover plate 12 is connected to one end of the lifting plate 11. The cover plate 12 is placed on the top of the outer cylinder 2. A limit ring 14 is connected to the outer side of the bottom of the cover plate 12. The inner wall of the limit ring 14 is in sliding contact with the top of the outer cylinder 2. A pressure gauge is installed on the top of the cover plate 12.

[0027] The liquid outlet 711 is located inside the dyeing cylinder 9. The outside of the filling tube 710 is movably connected to the outer cylinder 2 and the dyeing cylinder 9 through a sealed bearing. The bottom of the outside of the filling tube 710 is fixedly fitted with a driven gear 713. One side of one of the support legs 6 is connected to a mounting plate 72, and the top of the mounting plate 72 is connected to a rotary motor 73.

[0028] A drive gear 71, meshing with a driven gear 713, is fixedly sleeved on the top of the output end of the rotary motor 73. Connecting sleeve 1 79 and connecting sleeve 2 75 are sequentially and movably sleeved from top to bottom on the outside of the filling pipe 710 and located between connecting sleeve 1 79 and connecting sleeve 2 75, via sealed bearings. A solenoid valve 1 74 is installed on the outside of the filling pipe 710 and between connecting sleeve 1 79 and connecting sleeve 2 75.

[0029] In use, the extension end of the electric telescopic column 15 is extended by controlling the peripheral control cabinet of the dyeing machine, which drives the lifting plate 11, the cover plate 12 and the limiting ring 14 to rise. Then, the frequency conversion drive motor 16 runs, driving the electric telescopic column 15 and the components on its top to rotate together, so that the cover plate 12 and the limiting ring 14 are separated from the top of the outer cylinder 2, so that the dyeing cylinder 9 is exposed. The yarn to be dyed is put into the dyeing cylinder 9, and then each component is reset in sequence.

[0030] The external dyeing pump, solenoid valve 74, and rotary motor 73 are turned on. The pump draws high-temperature dye from the outside into the dyeing tube 710, which is then ejected from the outlet 711. The rotary motor 73 drives the drive gear 71 to rotate, which, in turn, drives the dyeing tube 710 and the spray pipe 712 to rotate, ensuring even dye ejection. After dyeing is complete, the solenoid valve 74 and the external dyeing pump are turned off. When dye needs to be discharged after dyeing, the solenoid valve 77 and the external drain pump are opened, and the dye in the dyeing cylinder 9 is discharged through the outlet 711 and the dyeing tube 710. Before dyeing, the external vacuum pump must be turned on to evacuate the vacuum chamber to prevent excessive heat loss to the external environment.
