Description

Technical Field

[0001] This application relates to the field of equipment for pretreatment of polyester fabrics before dyeing, and in particular to a water washing device for pretreatment of polyester fabrics before dyeing. Background Technology

[0002] Polyester fabric is a textile made of polyester fibers. It has high strength and good elasticity and is widely used in clothing, home decoration and industrial products.

[0003] The dyeing process for polyester fabrics typically includes three stages: pretreatment, dyeing, and posttreatment. Pretreatment involves washing, acid washing, and alkali washing to remove impurities from the fabric and adjust the pH value. Dyeing involves selecting dyes and auxiliaries for dyeing, followed by thorough washing to remove excess dyes and auxiliaries. Posttreatment involves steps such as softening, drying, finishing, and packaging to improve the softness and comfort of the fabric and ensure product quality.

[0004] When polyester fabrics are pre-treated with water washing, the washing solution contains a large amount of lint and other impurities that easily adhere to the fabric. This can lead to uneven dyeing and poor dye penetration during subsequent dyeing processes. Usually, a filtration device is used to filter the washing solution and then recycle it to save water resources. After a long period of use, the filtration device needs to be replaced. However, the filtration device is usually fixed in place by bolts or other means, making it inconvenient to disassemble and replace. Utility Model Content

[0005] To address the inconvenience of replacing fixed-installation filter devices, this application provides a water washing device for pretreatment of polyester fabrics before dyeing.

[0006] The water washing device for pre-dyeing polyester fabric provided in this application adopts the following technical solution:

[0007] A pretreatment water washing device for polyester fabric dyeing includes a treatment box, a guide roller for conveying the fabric is provided inside the treatment box, a filter assembly is provided on one side of the treatment box, the filter assembly includes a filter box on one side of the treatment box and a filter mechanism provided inside the filter box, the filter box is connected to the treatment box at opposite sides by an inlet pump and an outlet pump respectively, the filter mechanism includes a filter plate and an adsorption plate slidably mounted on the filter box, the filter plate and the adsorption plate are distributed parallel to each other, a locking member is provided on the filter box, the locking member slides in a direction perpendicular to the sliding direction of the filter plate, the locking member is used to lock the filter plate and the adsorption plate.

[0008] By adopting the above technical solution, during operation, the fabric is transported to the treatment box for washing via guide rollers. The inlet pump delivers the washing liquid from the treatment box to the filter box. After being processed by the filter plate and adsorption plate in the filter box, it is then transported back to the treatment box for reuse by the outlet pump. When the filter plate and adsorption plate need to be replaced, the sliding locking part is moved to separate from the filter plate and adsorption plate. At this time, the filter plate and adsorption plate are slid out for replacement. Then, the new filter plate and adsorption plate are installed. At this time, the locking part slides to lock the filter plate and adsorption plate. The disassembly and assembly of the filter plate and adsorption plate are convenient.

[0009] Optionally, the locking component includes a rack and a rod.

The rod is slidably inserted into the filter plate and the adsorption plate through the slots. The filter box is provided with a limiting component for limiting the rack.

[0010] By adopting the above technical solution, the rotating gear drives the rack to slide, thereby driving the rod at one end of the rack to be inserted into the slots of the filter plate and the adsorption plate, fixing the position of the filter plate and the adsorption plate. At this time, the limiting component limits the position of the rack, reducing the probability of the filter plate and the adsorption plate becoming loose.

[0011] Optionally, the rack is located between the filter plate and the adsorption plate. There are two racks located on opposite sides of the gear. The insertion rod of one rack is located at the end of the rack facing the filter plate, and the insertion rod of the opposite rack is located at the end of the rack facing the adsorption plate.

[0012] By adopting the above technical solution, when the gear is rotated, the gear drives the racks on both sides to move simultaneously. The insertion rod at one end of one rack inserts and locks the filter plate, while the insertion rod at one end of the other rack inserts and limits the adsorption plate. The synchronous drive locks the filter plates and adsorption plates on both sides, making the locking operation convenient.

[0013] Optionally, the filter box is provided with a mounting bracket, the mounting bracket is provided with a rotating rod, the rotating rod is coaxially connected to the gear, and a rotating handwheel is provided at the end of the rotating rod opposite to the gear.

[0014] By adopting the above technical solution, the rotation of the handwheel drives the rotation rod to rotate, which in turn drives the gear to rotate. The gear drives the rack to slide and lock, making the operation of driving the gear to rotate convenient.

[0015] Optionally, a guide rod is provided on the side of the rack away from the insertion rod, the guide rod is slidably connected to the mounting bracket, a return spring is sleeved on the guide rod, one end of the return spring is connected to one end of the rack, and the end of the return spring away from the rack is connected to the mounting bracket.

[0016] By adopting the above technical solution, when the rack slides, it drives the guide rod at one end to slide. The guide rod guides the sliding of the rack. When the limiting component releases the limit, the reset spring drives the rack to reset, which facilitates the quick unlocking of the filter plate and the adsorption plate.

[0017] Optionally, the limiting component includes a locking rod and a stop bar. The locking rod is slidably mounted on the filter box, and the sliding direction of the locking rod is perpendicular to the sliding direction of the rack. The stop bar is disposed on one side of the rack, and one side of the stop bar abuts against one side of the locking rod.

[0018] By adopting the above technical solution, when the rack slides to the insertion point of the insert rod and is inserted into the filter plate, the locking rod slides to one side of the locking rod to abut against one side of the stop bar to limit the rack, thereby limiting the rack. The rack limiting operation is convenient.

[0019] Optionally, the filter box is provided with a sliding box, the sliding box has a guide groove, the clamping rod is slidably connected to the sliding box through the guide groove, and the sliding box is provided with a limit spring at the guide groove, one end of the limit spring is connected to one end of the clamping rod.

[0020] By adopting the above technical solution, when it is necessary to limit the rack, the limiting spring pushes the locking rod to slide to the side of the stop bar, which facilitates the limiting of the stop bar.

[0021] Optionally, a pull rod is slidably mounted on the sliding box, one end of the pull rod is located at the guide groove and connected to one side of the clamping rod, and the end of the pull rod away from the clamping rod is located on the outside of the sliding box.

[0022] By adopting the above technical solution, pulling the lever causes the locking rod to slide in the guide groove of the sliding box, making the sliding operation of the locking rod convenient.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the filter plate and adsorption plate need to be replaced, slide the locking parts to separate them from the filter plate and adsorption plate.

At this time, the return spring 412 pulls the rack 41 to slide, and the rack 41 drives the insertion rod 42 on one side to move. The racks 41 on both sides slide synchronously. At this time, the insertion rod 42 separates from the filter plate 31 and the adsorption plate 32, and the filter plate 31 and the adsorption plate 32 separate from the filter box 2. Slide the filter plate 31 and the adsorption plate 32 out and replace them with new ones. The filter plate 31 and the adsorption plate 32 are slidably installed on the sliding holes 23 on both sides along the guide rod 24. At this time, the handwheel 252 is turned to drive the rotating rod 251 to rotate, which in turn drives the gear 43 to rotate. The gear 43 drives the racks 41 on both sides to slide to the insertion rod 42 and insert and fix them between the filter plate 31 and the adsorption plate 32. At this time, the limiting spring 532 on one side of the clamping rod 51 pushes the clamping rod 51 to abut against the side of the stop bar 52, completing the installation.
