Description

Technical Field

[0001] The invention belongs to the technical field of cloth hair removal, and in particular relates to a pretreatment device for finished clothes before dyeing. Background Art

[0002] Finished fabrics, such as clothing and bed sheets, typically undergo a cooking and etching process before dyeing. Existing workshop production typically uses a one-bath process, where the etching agent and dye are added to the dye vat simultaneously, performing the etching and dyeing processes. However, in laboratory dye development, using the one-bath process makes it difficult to assess the dyeing effect of the dye. Furthermore, the long dyeing time associated with the one-bath process affects experimental efficiency. Without cooking and etching, inconsistent dyeing results can occur between the laboratory and workshop production.

[0003] For this reason, it is necessary to design a device that can pre-treat the fabric before dyeing. Summary of the Invention

DETAILED DESCRIPTION

[0024] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this solution.

[0025] like Figures 1 to 3 As shown, this embodiment designs a pretreatment device for finished clothes before dyeing, including a frame 9, a processing tank 1, a grouting pipe 2, a turning net cylinder 3, a control console 4, a distribution box 5, a roller 8, a frame 9, a driving mechanism, a drain pipe 14, an overflow pipe 15, a temperature sensor 11, an electric heater 12 and other components.

[0026] The frame 9 is a frame structure, and side panels are fixed to the outer periphery of the frame 9 to shield the frame 9.

[0027] The processing tank 1 is arranged in the frame 9, with the notch of the processing tank 1 facing upward. The upper half of the processing tank 1 is a square cavity, and the lower half of the processing tank 1 is a semicircular cavity. The notch of the processing tank 1 is located on the table top of the frame 9; a pulp tank cover is hinged at the notch, and the rear side of the pulp tank cover is rotatably connected to the rear side of the notch of the processing tank 1. A lock is provided on the front side of the notch of the processing tank 1, which can lock the front side of the pulp tank cover; after the lock locks the pulp tank cover, the pulp tank cover cannot be opened upward. After the lock unlocks the pulp tank cover, the pulp tank cover can be opened upward.

[0028] A processing tank 1 is provided on the frame 9, and the processing tank 1 is connected to an overflow pipe 15, a grouting pipe 2 and a drain pipe 14, and electromagnetic valves are connected to the grouting pipe 2 and the drain pipe 14. When the electromagnetic valve on the grouting pipe 2 is opened, liquid or clean water can be injected into the processing tank 1 through the grouting pipe 2, and when the electromagnetic valve on the drain pipe 14 is opened, the liquid can be discharged through the drain pipe 14.

[0029] The tumbler 3 is disposed horizontally within the treatment tank 1 and is capable of continuously tumbling within the treatment tank 1. The tumbler 3 has a plurality of mesh holes on its wall. When finished garments are placed within the tumbler 3, liquid can enter the tumbler 3 through the mesh holes, soaking the finished garments and achieving hair removal. Furthermore, as the tumbler 3 tumbles, the finished garments continuously move within the tumbler 3, thereby improving the uniformity and quality of hair removal.

[0030] The wall of the reversing net cylinder 3 is provided with a take-in / put-out opening, to which a curved door is hinged. Finished clothes can be taken in and out through the take-in / put-out opening, and the curved door can cover the reversing net cylinder 3 to prevent the reversing net cylinder 3 from falling out of the take-in / put-out opening during the reversing process.

[0031] The inner wall of the turning net cylinder 3 is provided with a stop bar, which can prevent the finished clothes from sliding along the wall of the turning net cylinder 3, thereby ensuring that the finished clothes can roll in the turning net cylinder 3, thereby ensuring the quality of the etched hair.

[0032] A drive mechanism is also provided on the frame 9. The drive mechanism is in transmission connection with the revolving net drum 3 and controls the revolving of the horizontally disposed revolving net drum 3. The drive mechanism is mounted within the frame 9 and located outside the processing tank 1. The drive mechanism comprises, among other components, a drive motor 6 and a reducer 7. The rotating shaft of the drive motor 6 is connected to the input end of the reducer 7, the output end of which is connected to a driving pulley. A driven pulley 10 is coaxially connected to the revolving net drum 3, and the driving and driven pulleys 10 are connected by a belt. When the drive motor 6 is energized and rotates in a forward, reverse, or alternating direction, it drives the revolving net drum 3 to rotate, thereby achieving hair removal. Furthermore, the high-speed rotation of the revolving net drum 3 by the drive mechanism dehydrates the finished garments under the action of centrifugal force, thereby improving liquid recovery and reducing the number of washes required when washing with purified water.

[0033] The inner bottom of the treatment tank 1 is provided with an elongated bottom tank 13, with an electric heater 12 and a temperature sensor 11 mounted at each end. The electric heater 12 can heat the liquid in the treatment tank 1, while the temperature sensor 11 can detect the liquid, thereby facilitating feedback control of the liquid temperature, ensuring that the finished garments are etched under process temperature conditions, and guaranteeing the etched quality and pass rate. A drain pipe 14 is connected to the bottom tank 13. After the etch is complete, the liquid can be drained through the drain pipe 14, and then clean water can be injected into the treatment tank 1 for cleaning. At the same time, because the drain pipe 14 is located at the lowest point of the treatment tank 1, it can ensure that the liquid is completely drained. This further improves the liquid recovery rate and further reduces the number of cleaning times when using clean water for cleaning.

[0034] The end of the bottom tank is also communicated with a steam pipe, which is connected to a steam device and is used to send steam into the treatment tank to heat the liquid.

[0035] The bottom of the frame 9 is provided with rollers 8 to facilitate the movement of the frame 9. The top of the frame 9 is provided with a table shield. Above the table shield is provided a console 4, which is provided with a switch and a display screen. The switch can be used to control the start and stop of the motor and the operating power, and the display screen can be used to conveniently view the set operating parameters and operating status.

[0036] End shafts are respectively provided at both ends of the flip net cylinder 3. The end shafts do not pass through the center of the flip net cylinder 3, but only extend outward from both ends of the flip net cylinder 3. The two end shafts are connected to the groove wall of the processing tank 1 through bearings, so that the flip net cylinder 3 can rotate in the processing tank 1 with lower resistance. One of the end shafts extends out of the processing tank 1 and is connected to the driven pulley 10. The drive motor 6 controls the rotation of the flip net cylinder 3 through the end shaft.

[0037] The above embodiments are merely examples for the purpose of illustrating the present invention clearly and are not intended to limit the embodiments. It is not necessary and impossible to enumerate all embodiments here. Obvious changes or modifications derived therefrom are still within the scope of protection of this technology.
