Description

Technical Field

[0001] This utility model belongs to the field of fabric pretreatment technology, and specifically relates to a fabric washing device. Background Technology

[0002] In the fabric production process, the fabric needs to be washed before dyeing to remove oil, dirt, and soil from the fabric surface.

[0003] Currently, Chinese patent CN218372815U, published on January 24, 2023, discloses a washing device for spandex fabrics, including a washing tank. Multiple guide rollers are rotatably arranged within the washing tank, distributed along the length of the washing tank. A first pipe is connected to the washing tank, and a first valve is installed on the first pipe. A first pump is connected to the end of the first pipe away from the washing tank, and the first pipe is connected to the negative pressure port of the first pump. A second pipe is connected to the positive pressure port of the first pump. A filter box is connected to the end of the second pipe away from the first pump. A third pipe is connected to the side of the filter box opposite to the second pipe, and a second pump is connected to the end of the third pipe away from the filter box. The third pipe is connected to the negative pressure port of the second pump, and a fourth pipe is connected to the positive pressure port of the second pump. The end of the fourth pipe away from the second pump is connected to the washing tank, and a second valve is installed on the fourth pipe.

[0004] This type of washing device for spandex fabrics uses multiple guide rollers to allow the fabric to be immersed in and out of the water, thus washing the fabric. However, during long-term fabric washing in the washing tank, the tank is in a large open state for an extended period of time. Furthermore, the air environment in the fabric processing workshop often contains a lot of floating matter such as cotton fibers. This can easily lead to the floating matter entering the washing tank and contaminating the washing water. Utility Model Content

[0005] The purpose of this invention is to provide a fabric washing device that can reduce floating matter entering the washing tank.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fabric washing device, including a washing tank, multiple guide rollers for the fabric to pass through and arranged alternately, an unwinding shaft rotatably connected to one end of the washing tank, and a winding shaft rotatably connected to the other end of the washing tank. Each of the four corners on the upper side of the washing tank is provided with a column, and a frame plate is provided between the upper ends of the four columns. A central cylinder is provided at the center of the frame plate, and a cover plate for covering the upper surface of the washing tank is fixed to the piston rod end of the central cylinder. Each of the four corners of the cover plate is rotatably connected with pulleys that abut against the columns. Multiple first support arms are provided on one side of the cover plate, each connecting one end of one of the multiple guide rollers, and multiple second support arms are provided on the other side of the cover plate, each connecting the other end of one of the multiple guide rollers.

[0007] A further feature of this invention is that the second support arm includes a fixed arm whose upper end is fixedly connected to the cover plate, a cavity portion opened at the lower side of the fixed arm, and a rotating arm whose upper end is rotatably connected to the lower end of the cavity portion. The guide roller is provided with a support shaft at one end of the rotating arm, and the rotating arm is provided with an arc-shaped support groove for the support shaft to be embedded after rotation.

[0008] A further feature of this invention is that a rubber limiting protrusion is provided inside the cavity. When the rotating arm rotates toward the cavity and retracts into the cavity, the side of the rotating arm abuts against the surface of the rubber limiting protrusion.

[0009] A further feature of this invention is that: a connecting sleeve communicating with the cavity is provided on the fixed arm; a connecting shaft passing through the connecting sleeve and connected to the rubber limiting protrusion is provided on the connecting sleeve; an external threaded post is provided at one end of the connecting shaft outside the fixed arm; and a reset spring is sleeved on the connecting shaft, with one end connected to the external threaded post and the other end connected to the connecting sleeve.

[0010] A further feature of this invention is that the lower end of the first support arm is provided with an internal threaded sleeve, and the end of the guide roller is provided with a threaded shaft threadedly connected to the internal threaded sleeve.

[0011] A further feature of this invention is that a lower pressure roller for abutting against the lower surface of the fabric is rotatably connected at one end of the washing tank and the end near the take-up shaft; a bracket is provided on the washing tank at both ends of the lower pressure roller; and an upper pressure roller for abutting against the upper surface of the fabric is provided between the two brackets.

[0012] A further feature of this invention is that the support is provided with a lifting cylinder at the end of a piston rod for rotating connection to the upper pressure roller.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. When the fabric needs to be washed, the central cylinder first moves the cover plate upward, thereby moving multiple guide rollers to the position above the washing tank. Then, the operator can manually pass the fabric in an S-shape between the multiple guide rollers, which facilitates the stable transfer of the fabric between the multiple guide rollers. Then, the central cylinder moves the cover plate downward, thereby moving multiple guide rollers into the washing tank and immersing the fabric below the water surface. At the same time, the cover plate can be closed on the upper surface of the washing tank, thus sealing the washing tank and reducing the amount of floating matter entering the washing tank.

[0015] 2. When the operator needs to manually pass the fabric in an S-shape between multiple guide rollers, the arc-shaped support groove of the rotating arm allows the support shaft at the end of the guide roller to be inserted. After the operator swings the rotating arm upward, it can be retracted into the cavity. At this time, the empty space of the rotating arm makes it convenient for the operator to pull the fabric through multiple guide rollers without switching hands, which ultimately facilitates the easy passage of the fabric through multiple guide rollers.

[0016] 3. When the rotating arm swings upward and is embedded in the cavity, the rotating arm can press against the rubber limiting protrusion. The friction between the rubber limiting protrusion and the rotating arm can position the rotating arm, which is conducive to the stable storage of the rotating arm in the cavity.

[0017] 4. When it is necessary to pull out the rotating arm from the cavity, simply pull the external threaded column outward to remove the rubber limiting protrusion that is pressed against the rotating arm, and the return spring is compressed. At this time, after the pressing effect of the rubber limiting protrusion is lost, the rotating arm can be easily pulled out from the cavity, which will facilitate the convenient entry and exit of the rotating arm in the cavity.

[0018] 5. When it is necessary to disassemble and replace the guide roller, first swing the rotating arm upward and embed it into the cavity, then rotate the guide roller so that the threaded shaft at the end of the guide roller moves out of the inner threaded sleeve, and finally the guide roller can be easily disassembled and installed.

[0019] 6. The upper and lower pressure rollers are pressed against the upper and lower surfaces of the fabric, which helps to squeeze out the water from the fabric and realize water recycling.

[0020] 7. By using a lifting cylinder to move the upper pressure roller up and down to change its height, different spacing can be provided for fabrics of different thicknesses. At the same time, the upward movement of the upper pressure roller also creates space for the fabric to pass through. Attached Figure Description

Detailed Implementation

[0028] The technical solutions in the embodiments will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] A fabric washing device, as described in the following description Figure 1 The fabric washing device includes a washing tank 1, guide rollers 2, unwinding shaft 11, and rewinding shaft 12. Multiple guide rollers 2 are arranged in a staggered pattern, allowing the fabric to pass through in an S-shape. The unwinding shaft 11 is rotatably connected to one end of the washing tank 1, while the rewinding shaft 12 is rotatably connected to the other end. A motor and transmission mechanism drive the rewinding shaft 12 to provide power for fabric transport. A lower pressure roller 6, which abuts against the lower surface of the fabric, is rotatably connected to one end of the washing tank 1 near the rewinding shaft 12 via a bearing seat. Supports 7 are bolted to both ends of the lower pressure roller 6 on the washing tank 1. An upper pressure roller 71, which abuts against the upper surface of the fabric, is positioned between two supports 7. A lifting cylinder 72, with a piston rod end bolted to the support 7, is rotatably connected to the upper pressure roller 71 via a bearing seat.

[0030] Reference Figure 1 , Figure 2 , Figure 3Each of the four corners on the upper side of the washing tank 1 is welded with a column 13. A frame plate 14 is integrally set between the upper ends of the four columns 13. A central cylinder 141 is fixed to the center of the frame plate 14 by bolts. The piston rod end of the central cylinder 141 is fixed to a cover plate 3 by bolts. When the cover plate 3 is lowered, it can be used to cover the upper surface of the washing tank 1. At the same time, each of the four corners of the cover plate 3 is rotatably connected to a pulley 31 that abuts against the column 13. Multiple first support arms 32 are welded to one side of the cover plate 3, which are respectively connected to one end of multiple guide rollers 2. The lower end of the first support arm 32 is integrally set with an internal threaded sleeve 321, and the end of the guide roller 2 is integrally set with a threaded shaft 22 that is threadedly connected to the internal threaded sleeve 321.

[0031] Reference Figure 2 , Figure 4 On the other side of the cover plate 3, there are multiple second support arms 4 for connecting the ends of multiple guide rollers 2 away from the first support arm 32. The second support arm 4 includes a fixed arm 41 whose upper end is welded and fixedly connected to the cover plate 3, a cavity 42 opened at the lower side of the fixed arm 41, and a rotating arm 43 whose upper end is rotatably connected to the lower end of the cavity 42 through a shaft and bearing. Meanwhile, the guide roller 2 is integrally provided with a support shaft 21 at one end of the rotating arm 43, and the rotating arm 43 is provided with an arc-shaped support groove 431 for the support shaft 21 to be inserted after rotation.

[0032] Reference Figure 2 , Figure 4 , Figure 5 The cavity 42 is also provided with a rubber limiting protrusion 5. When the rotating arm 43 rotates toward the cavity 42 and is retracted into the cavity 42, the side of the rotating arm 43 abuts against the surface of the rubber limiting protrusion 5. The fixed arm 41 is integrally provided with a connecting sleeve 411 that communicates with the cavity 42. The connecting sleeve 411 is provided with a connecting shaft 412 that passes through the connecting sleeve 411 and is bonded to the rubber limiting protrusion 5. At the same time, an external threaded post 413 is integrally provided at one end of the connecting shaft 412 located outside the fixed arm 41. A return spring 414 is sleeved on the connecting shaft 412, with one end fixedly connected to the external threaded post 413 and the other end fixedly connected to the connecting sleeve 411.

[0033] Principle: When the fabric needs to be washed, the central cylinder 141 first moves the cover plate 3 upward, thereby moving multiple guide rollers 2 to a position above the washing tank 1. Then, the operator can manually pass the fabric in an S-shape between the multiple guide rollers 2, which facilitates the stable transfer of the fabric between the multiple guide rollers 2. Then, the central cylinder 141 moves the cover plate 3 downward, thereby moving multiple guide rollers 2 into the washing tank 1 and immersing the fabric below the water surface. At the same time, the cover plate 3 can be closed on the upper surface of the washing tank 1, thus sealing the washing tank 1 and reducing the amount of floating matter entering the washing tank 1.

[0034] When the operator needs to manually pass the fabric in an S-shape between multiple guide rollers 2, the arc-shaped support groove 431 of the rotating arm 43 allows the support shaft 21 at the end of the guide roller 2 to be inserted. After the operator swings the rotating arm 43 upward, it can be retracted into the cavity 42 and limited by the rubber limiting protrusion 5. At this time, the empty position of the rotating arm 43 makes it convenient for the operator to pull the fabric through the multiple guide rollers 2 without switching hands, which ultimately facilitates the convenient passage of the fabric through the multiple guide rollers 2.
