Description

Technical Field

[0001] The utility model relates to the technical field of fabric processing, in particular to a cold stack pre-treatment device. Background Art

[0002] The process principle of cold padding pretreatment of cotton fabric is consistent with the process principle of conventional descaling, boiling and bleaching pretreatment, except that the reaction conditions in the treatment process are milder, the amount of additives in the production process is increased, and the reaction time is prolonged. In order to ensure the stability and effectiveness of the pretreatment quality, some pretreatment additives need to be added. Through heavy cold padding, light bleaching, or even no bleaching, all the processing procedures of descaling, boiling and bleaching in the pretreatment are completed through a simple water washing. The low-carbon treatment process greatly reduces the use of steam, saves manpower and the cost of water and electricity, and improves the humid and hot production environment in the workshop.

[0003] In the prior art, most cold stack pre-treatment devices drive cotton fabrics to contact and react with treatment liquid by rotating rollers, but in this process, the position between the cotton fabric and the rotating rollers often shifts, affecting subsequent reactions. Cotton fabrics usually have wrinkles, and the wrinkles prevent the cotton fabrics from fully reacting with the treatment liquid, affecting the yield rate of the cotton fabrics. When the cotton fabrics are taken out of the treatment liquid, the cotton fabrics will bring out a large amount of treatment liquid, causing waste of the treatment liquid. When the cotton fabrics are subsequently collected manually, the labor intensity of the staff is increased. Therefore, in order to solve the above problems, the utility model proposes a cold stack pre-treatment device. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a cold stack pre-treatment device, which adapts to different cotton fabrics by driving the lifting frame to move through a hydraulic rod, thereby improving the applicability of the device; the threaded roller prevents the cotton fabric from shifting and regularizes the wrinkles of the cotton fabric, so that the cotton fabric and the treatment liquid fully react, thereby improving the yield rate of the cotton fabric; the filtrate roller reduces the waste of treatment liquid, thereby having good economic benefits; and the swinging frame swings, which is conducive to the collection of the cotton fabric after the reaction and reduces the labor intensity of the staff.

[0005] The utility model provides the following technical scheme: a cold stack pre-treatment device, comprising a liquid storage tank, hydraulic rods are evenly and fixedly installed at the corners of the upper part of the liquid storage tank, the number of the hydraulic rods is four, a lifting frame is fixedly installed on the protruding end of the hydraulic rod, a connecting block is fixedly installed on the left part of the lifting frame, the number of the connecting blocks is two and they are symmetrically distributed front to back, a threaded roller is movably sleeved between the two connecting blocks, the number of the threaded rollers is two and they are symmetrically distributed up and down, a rotating roller one is evenly and movably sleeved in the middle part of the lifting frame, the number of the rotating roller one is four, a rotating roller two is evenly and movably sleeved on the bottom of the inner cavity of the liquid storage tank, and a motor is fixedly installed at the rear of the lifting frame.

[0006] Preferably, a rotating shaft 1 is fixedly mounted on the motor output shaft, there are two rotating shafts 1 and they are movably sleeved on the upper and lower parts of the lifting frame respectively, and a filtrate roller is fixedly sleeved on the middle part of the rotating shaft 1.

[0007] Preferably, a transmission roller 1 is fixedly sleeved on the rotating shaft 1 and located behind the filtrate roller, a transmission belt is meshed on the outer extension of the transmission roller 1, and a transmission roller 2 is meshed on the right end of the transmission belt.

[0008] Preferably, a second rotating shaft is fixedly sleeved on the middle part of the second transmission roller, the second rotating shaft is movably sleeved on the right part of the lifting frame, and a third rotating roller is fixedly sleeved on the middle part of the second rotating shaft.

[0009] Preferably, the front and rear ends of the second rotating shaft are movably sleeved with swing frames respectively, and a fixed roller is fixedly installed between the two swing frames. The number of the fixed rollers is two and they are located on the right part of the swing frame.

[0010] Preferably, a turntable is fixedly sleeved on a front end of the rotating shaft, a traction rod is movably connected to the front of the turntable via an axis, and a right end of the traction rod is movably connected to a left end of a swing frame via an axis.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The hydraulic rod drives the lifting frame to rise so that the device can meet the needs of cotton fabrics with different tensile tensions, thereby improving the applicability of the device. The threads on the threaded roller increase the contact area with the cotton fabric, forming a better fixation to prevent the cotton fabric from shifting during processing. At the same time, the threads can be used to regularize the wrinkles on the cotton fabric to prevent the wrinkles from fully reacting with the treatment liquid. The cotton fabric is wound up and down between the rotating rollers, which increases the contact time between it and the treatment liquid, promotes complete reaction, and improves the yield rate of the device.

[0013] 2. The motor drives the rotating shaft to rotate, and the rotating shaft drives the filtrate roller to rotate. The two filtrate rollers squeeze the cotton fabric during rotation, so that the excess treatment liquid on the cotton fabric falls back into the inner cavity of the liquid storage tank, which allows the reacted cotton fabric to be quickly dried while reducing the waste of treatment liquid, thereby having good economic benefits. The rotating shaft drives the turntable to rotate at the same time, and the turntable drives the traction rod to move, and the traction rod drives the swing frame to swing the fixed roller, so that the cotton fabric forms a reciprocating swing and falls when passing through the fixed roller, which is beneficial to the collection of the cotton fabric, avoids the need for manual rearrangement, and reduces the labor intensity of the staff.
