[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-5As shown, a polyester dyeing device includes a heating base 212, on which a dyeing box 3 is mounted. A flip-up top cover 4 is mounted on the upper end of the dyeing box 3, and the top cover 4 is connected to the dyeing box 3 via a locking fastener 5. A mounting groove 6 is provided on one side of the upper end of the dyeing box 3, the length of which is greater than the length of the dyeing box 3. A ball screw 7 is rotatably connected inside the mounting groove 6, and a slide block 8 that slidably engages with the ball screw 7 is slidably connected inside the mounting groove 6. A servo motor 9 is provided on one side of the mounting groove 6 to drive the ball screw 7. A support frame 10 is mounted on the slide block 8, and a rotating shaft 11 is mounted on the support frame 10. A servo motor 12 is mounted on the upper end of the support frame 10, and the output end of the servo motor 12 and the rotating shaft 11 are respectively provided with mutually meshing conical... Gear 13 and shaft 11 are provided with limit rings 14 on their outer surfaces. The outer surface of the shaft 11 at the end away from the support frame 10 is provided with external threads. A sleeve 15 is threadedly connected to the external thread section of the shaft 11. A base plate 16 is provided inside the dyeing box 3. Drainage holes 17 are evenly provided on the base plate 16. Two sets of drive units for controlling the lifting and lowering of the base plate 16 are provided inside the dyeing box 3. The drive unit includes a ball screw 18 provided on the inner side wall of the dyeing box 3. A placement cavity 19 is provided on the inner side wall of the dyeing box 3. A servo motor 20 for driving the ball screw 18 to rotate is provided inside the placement cavity 19. A base 21 is threadedly connected to the ball screw 18. A through groove is provided on the base plate 16. The base 21 and the through groove are connected by an elastic and annular gasket 22.

[0019] The heating base 212 uses electromagnetic heating to heat the dye solution inside the dyeing box 3, and is equipped with a corresponding temperature sensor and controller to maintain the temperature of the dye solution inside the dyeing box 3 at about 70℃-85℃. At the same time, a valve is provided on the side of the dyeing box 3, and an external pipe is connected to the valve to transport external dye solution into the dyeing box 3. The dye solution in the dyeing box 3 can also be discharged through the valve. The valve is located at a low position on the side of the dyeing box 3. When the dye solution is transported into the dyeing box 3 through the valve, the dyeing can be stably transported, and the large amount of foam generated when the dye is poured directly into the dyeing box 3 can be reduced.

[0020] Before dyeing the polyester fabric, the polyester fabric roll 1 is first placed on the rotating shaft 11, with one end of the polyester fabric roll 1 abutting against the limiting ring 14. Then, by rotating the sleeve 15, the polyester fabric roll 1 is fixed on the rotating shaft 11. Next, the servo motor 12 is started. The output end of the servo motor 12 drives the rotating shaft 11 to rotate through the meshing of two bevel gears 13. During the rotation of the rotating shaft 11, under the action of gravity, the polyester fabric roll 1 will be in an unwinding state, and the polyester fabric will move downwards. The polyester fabric roll 1 is in an unwinding state. During the process, servo motor 9 is started, and its output drives ball screw 7 to rotate. Through the cooperation of ball screw 7 and slide 8, slide 8 moves linearly within mounting groove 6. Then, by controlling the forward and reverse rotation of servo motor 9, slide 8 moves reciprocating linearly within mounting groove 6. Simultaneously, the support frame 10, rotating shaft 11, and polyester fabric roll 1 above slide 8 move reciprocating linearly, allowing the polyester fabric released from polyester fabric roll 1 to be stacked layer by layer onto the base plate 16, as per the instruction manual. Figure 5 As shown, the polyester fabric is placed only within a predetermined area on the base plate 16 to avoid contact between the polyester fabric and the ball screw 18.

[0021] After the polyester fabric is placed on the base plate 16, the servo motor 9 controls the rotating shaft 11 to move away from the top of the dyeing box 3, and then the dye liquor is transported into the dyeing box 3. After the dye liquor is transported into the dyeing box 3, the top cover 4 is flipped to the top of the dyeing box 3, and then the top cover 4 is fixedly connected to the dyeing box 3 by the locking fastener 5. Then the dye liquor in the dyeing box 3 is heated by the heating base 212 to facilitate the dyeing of the polyester fabric on the base plate 16.

[0022] The liquid level of the dyeing solution in dyeing box 3 is lower than that in placement chamber 19 to ensure that servo motor 3 20 can be used normally, and at the same time, it is necessary to ensure that the polyester fabric can be completely immersed in the dyeing process.

[0023] A level gauge can be installed on the dyeing tank 3 to display the level of the dye solution inside. After dyeing the polyester fabric, the dye solution in the dyeing tank 3 is quickly released through the valve on the dyeing tank 3. When the level of the dye solution in the dyeing tank 3 is lower than the bottom plate 16, the two servo motors 20 located in the two placement chambers 19 start simultaneously. The servo motors 20 drive the ball screws 18 to rotate, and through the threaded connection between the ball screws 18 and the base 21, they drive the bottom plate 16 to move upward. Since the base 21 and the bottom plate 16 are connected by an elastic gasket 22 (the gasket 22 is made of rubber), and all sides of the bottom plate 16 maintain a distance of more than 4 cm from the opposite side of the dyeing tank 3, even if the two servo motors 20 cannot maintain absolute synchronous rotation, within the allowable error range, the deformation of the gasket 22 can still drive the bottom plate 16 to move upward. The base plate 16 moves upward, which in turn moves the polyester fabric on it upward until it contacts the lower surface of the top cover 4. The polyester fabric between the base plate 16 and the top cover 4 is then squeezed to squeeze out the dye liquor. The squeezed-out dye enters the bottom of the dyeing tank 3 through the drain hole 17 and is discharged through the valve on the dyeing tank 3. When the amount of dye discharged is small, the two servo motors 20 stop simultaneously. Then, the top cover 4 is opened by opening the locking fastener 5, and one end of the polyester fabric is fixed to the core of the polyester fabric roll 1. The servo motor 12 drives the rotating shaft 11 to rotate. The rotation of the core roll rolls up the polyester fabric on the base plate 16. The rolling does not need to keep both sides flat; it only needs to be rolled up for easy transfer to the washing tank for cleaning.

[0024] When the polyester fabric is squeezed through the top cover 4 and the bottom plate 16, the bottom plate 16 needs to have a relatively thick polyester fabric to prevent the polyester fabric on the bottom plate 16 from not being effectively squeezed when the bottom plate 16 can no longer move upward. That is, before the bottom plate 16 can no longer move upward, the dye liquor in the polyester fabric on the bottom plate 16 can be effectively squeezed out by the top cover 4 and the bottom plate 16.

[0025] A pressure relief valve is installed on the top cover 4 to facilitate the balance of air pressure inside the dyeing box 3.

[0026] Furthermore, the upper surface of the dyeing box 3 is provided with an elastic ring strip 23. When the top cover 4 is fixed to the upper end of the dyeing box 3, the ring strip 23 is in a compressed state, so as to improve the sealing between the top cover 4 and the dyeing box 3.

[0027] Furthermore, a handle 24 is provided on the upper surface of the top cover 4 to facilitate the control of the top cover 4's flipping. At the same time, when the bottom plate 16 moves upward and squeezes the polyester fabric located between the bottom plate 16 and the top cover 4, the handle 24 can improve the top cover 4's bending resistance.

[0028] Furthermore, a notch 25 is provided on the side of the dyeing box 3 and on one side of the placement cavity 19 to facilitate the connection between the placement cavity 19 and the outside, and to facilitate the heat dissipation of the servo motor 20.

[0029] Furthermore, a through hole 26 is provided at the bottom of the mounting tank 6. When some dye liquid enters the mounting tank 6, the dye liquid that has entered the mounting tank 6 can be discharged through the through hole 26.

[0030] As the equipment is used continuously, when the height difference between the bases 21 on the two ball screws 21 is 1cm-1.5cm, the equipment can be maintained. One of the servo motors 20 can be started separately and eventually the two bases 21 can be kept at approximately the same height to reduce the height difference between the two bases 21 and ensure the normal use of the device.

[0031] In the description of this utility model, 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 can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
