Description

Technical Field

[0001] This utility model belongs to the field of textile production technology, and in particular relates to a dyeing device for knitted fabric. Background Technology

[0002] Knitted fabric dyeing refers to the process of dyeing untreated knitted fabric to give it the desired color and appearance. During the dyeing process, the dye is inside the dye box. With the cooperation of the winding mechanism and the conveying mechanism, the knitted fabric is immersed in the dye and passes through the dye at a uniform speed to achieve dyeing.

[0003] A search revealed that CN220149828U, authorized on December 8, 2023, discloses a dyeing device for knitted fabrics, including a support plate, two sets of support rods, auxiliary components, and a dyeing component. The two sets of support rods are symmetrically installed on the top of the support plate by bolts. This utility model, through the inclusion of auxiliary components, allows for the adjustment of the height of a first ironing roller using a first electric push rod, enabling the ironing of knitted fabrics of different thicknesses. The first and second ironing rollers are used to iron the knitted fabric, preventing wrinkles on the fabric surface from affecting the uniform dyeing process. The second electric push rod allows for the adjustment of the height of a first pressing roller, enabling the compression of knitted fabrics of different thicknesses. The first and second pressing rollers are used to compress the dyed knitted fabric, squeezing out the moisture carried by the fabric. The water flows back into the dyeing chamber through a connecting cavity. A heating plate is used to dry the knitted fabric to a certain extent.

[0004] Existing technologies use a winding mechanism and a conveying mechanism to uniformly transport knitted fabric. However, during the transport process, the knitted fabric is prone to wrinkling, which affects the dyeing effect. Furthermore, existing technologies also affect the dyeing effect when there are impurities and lint on the surface of the knitted fabric. Therefore, we provide a knitted fabric dyeing device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a dyeing device for knitted fabrics. The device uses a rotating spiral rib to flatten the knitted fabric to avoid wrinkles, and uses a rotating brush to remove impurities and lint from the surface of the knitted fabric. This solves the problem that existing technologies can easily affect the dyeing effect of knitted fabrics due to wrinkles, and that dyeing can also affect the dyeing effect when there are impurities and lint on the surface of the knitted fabric.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a dyeing device for knitted fabric, comprising a dyeing mechanism. The dyeing mechanism includes a box body located outside the knitted fabric body. A rotating roller is provided on the upper left side of the box body. Spiral ribs are fixed on both the front and rear sides of the outer peripheral wall of the rotating roller, with the spiral directions of the two spiral ribs being opposite. Connecting rods are coaxially fixed at both the front and rear ends of the rotating roller. A movable plate is provided on the outside of the connecting rods, and a guide box is provided with a clearance fit on the outside of the movable plate. A cleaning mechanism is provided on the left side of the box body. The cleaning mechanism includes a U-shaped plate. Rotating rods are rotatably connected to the upper and lower parts of the knitted fabric body corresponding to the interior of the U-shaped plate through bearings. Brush bristles are fixed on the outer peripheral wall of the rotating rods. A filter box is fixed on the upper wall of the U-shaped plate. A filter plate is provided on the front side inside the filter box. A negative pressure fan is fixed on the front wall of the filter box.

[0008] The present invention is further configured such that a guide roller is provided on the lower side of the box body, and side plates are symmetrically provided in front of and behind the guide roller. The side plates are fixedly connected to the box body, and the guide roller is rotatably connected to the side plates through bearings.

[0009] The present invention is further configured such that a flattening motor is fixedly mounted on the front wall of the movable plate located on the front side, the power output shaft of the flattening motor is fixedly connected to the corresponding connecting rod, and the connecting rod is rotatably connected to the corresponding movable plate through a bearing.

[0010] The present invention is further configured such that the guide box is fixedly connected to the housing, the lower wall of the movable plate is fixedly provided with an elastic element, the lower end of the elastic element abuts against the housing, the side wall of the guide box is provided with a rectangular groove, and the interior of the rectangular groove is provided with a protrusion corresponding to the lower end of the movable plate.

[0011] The present invention is further configured such that a cleaning motor is fixedly mounted on the front wall of the U-shaped plate, the power output shaft of the cleaning motor is fixedly connected to the corresponding rotating rod, and gears are symmetrically mounted on the rear of the U-shaped plate, the two gears are meshed and connected, and the gears are fixedly connected to the corresponding rotating rods.

[0012] The present invention is further configured such that a mounting plate is fixedly provided on the lower wall of the U-shaped plate, the mounting plate is fixedly connected to the box body, and a three-way pipe is fixedly provided on the rear wall of the filter box, the other two ends of the three-way pipe being fixedly connected to the upper wall of the U-shaped plate and the mounting plate respectively.

[0013] The present invention is further configured such that a cover is fixedly provided on the upper wall of the filter box, and limiting strips are symmetrically provided on the left and right sides of the rear wall of the filter plate, and the limiting strips are fixedly connected to the filter box.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, by setting up a flattening motor, a rotating roller, and spiral ribs, allows the knitted fabric body to contact the top of the rotating roller while being conveyed. The flattening motor drives the rotating roller to rotate, causing both spiral ribs to rotate. When the spiral ribs rotate, they can apply an outward force to the knitted fabric body, pushing the wrinkled parts of the knitted fabric body to unfold outward, thereby achieving a flattening effect on the knitted fabric body. This avoids the situation where wrinkles in the knitted fabric body affect the dyeing effect.

[0016] 2. This utility model, by setting up brush bristles, a cleaning motor, a filter plate, and a negative pressure fan, allows the knitted fabric body to pass between two rotating rods. When the cleaning motor is working, the brush bristles on the outside of the two rotating rods rotate under the cooperation of the two gears, thereby achieving the cleaning treatment of both surfaces of the knitted fabric body to remove impurities and lint. At the same time, the negative pressure generated by the working fan draws impurities and lint into the filter box, where the filter plate traps the impurities and lint, thus achieving the purpose of preventing surface impurities and lint from affecting the dyeing effect.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 1-4 This utility model is a dyeing device for knitted fabric, including a dyeing mechanism 2. The dyeing mechanism 2 includes a box 201 located outside the knitted fabric body 1. The box 201 contains dye, and the liquid level of the dye is higher than the horizontal plane of the bottom of the guide roller 202. A rotating roller 205 is located above the left side of the box 201. Spiral ribs 205a are fixed on both the front and rear sides of the outer peripheral wall of the rotating roller 205. The spiral directions of the two spiral ribs 205a are opposite. The rotating roller 205 and the spiral ribs 205a are in contact with the knitted fabric body 1. The rotation of the spiral ribs 205a is used to flatten the knitted fabric body 1. Connecting rods 205b are coaxially fixed at both the front and rear ends of the rotating roller 205. A moving plate 204 is located outside the connecting rods 205b. A guide box 203 is provided on the outside of the moving plate 204 with a clearance fit, so that the moving plate 204 can move up and down.

[0030] Specifically, a guide roller 202 is provided on the lower side inside the housing 201. The guide roller 202 is in contact with the knitted fabric body 1, so that the guide roller 202 is below the dye liquid surface to achieve dyeing. Side plates 202a are symmetrically provided in front of and behind the guide roller 202. The side plates 202a are fixedly connected to the housing 201. The guide roller 202 is rotatably connected to the side plates 202a through bearings. When the knitted fabric body 1 moves at a constant speed from left to right, the guide roller 202 moves accordingly.

[0031] A flattening motor 206 is fixedly installed on the front wall of the movable plate 204 located on the front side. The power output shaft of the flattening motor 206 is fixedly connected to the corresponding connecting rod 205b. The connecting rod 205b is rotatably connected to the corresponding movable plate 204 through a bearing. With the above configuration, when the flattening motor 206 is working, it can drive the rotating roller 205 to rotate, so that the spiral rib 205a rotates.

[0032] The guide box 203 is fixedly connected to the housing 201. An elastic element 207 is fixedly provided on the lower wall of the movable plate 204. The setting of the elastic element 207 allows the rotating roller 205 to move up and down slightly, so as to avoid the knitted fabric body 1 being too tight or too loose. The lower end of the elastic element 207 abuts against the housing 201. A rectangular groove 203a is provided on the side wall of the guide box 203. A protrusion 204a is fixedly provided inside the rectangular groove 203a corresponding to the lower end of the movable plate 204. The protrusion 204a always moves within the rectangular groove 203a, which can prevent the movable plate 204 from detaching from the guide box 203.

[0033] like Figure 2 As shown, the movement path of the knitted fabric body 1 is as follows: the conveying mechanism (not shown in the figure) releases the knitted fabric body 1, the knitted fabric body 1 passes between the bristles 304a outside the two rotating rods 304, and passes around the rotating roller 205 and the guide roller 202 in sequence, and the winding mechanism (not shown in the figure) winds up the dyed knitted fabric body 1.

[0034] Furthermore, such as Figure 3 As shown, in this view, in order to achieve the effect of flattening the knitted fabric body 1 by rotating the spiral ridge 205a, the rotating roller 205 rotates in a clockwise direction;

[0035] The operation process of this embodiment is as follows: During dyeing, the flattening motor 206 drives the connecting rod 205b to rotate, which causes the rotating roller 205 to rotate, thereby causing the spiral ridge 205a to rotate. The spiral ridge 205a in the rotating state flattens the knitted fabric body 1. Then, the flattened knitted fabric body 1 is immersed in the dye under the action of the guide roller 202 for dyeing, and is finally wound up by the winding mechanism.

[0036] Example 2

[0037] Please see Figure 1 , 25, 6, and 7 are the second embodiment of this utility model. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: a cleaning mechanism 3 is provided on the left side of the box 201. The cleaning mechanism 3 includes a U-shaped plate 303. The upper and lower parts of the knitted fabric body 1 are rotatably connected to the interior of the U-shaped plate 303 via bearings. The outer peripheral wall of the rotating rod 304 is fixed with bristles 304a. The bristles 304a on the outside of the rotating rod 304 are annular. A filter box 305 is fixed on the upper wall of the U-shaped plate 303. The upper side of the filter box 305 is open. A filter plate 308 is provided on the front side inside the filter box 305 for collecting and filtering impurities and lint. A negative pressure fan 306 is fixed on the front wall of the filter box 305 for sucking impurities and lint into the filter box 305.

[0038] Specifically, a cleaning motor 307 is fixedly installed on the front wall of the U-shaped plate 303. The power output shaft of the cleaning motor 307 is fixedly connected to the corresponding rotating rod 304. Gears 304b are symmetrically arranged at the rear of the U-shaped plate 303, so that the two rotating rods 304 rotate synchronously. At the same time, the two rotating rods 304 rotate in opposite clockwise directions. The two gears 304b are meshed and connected. The gears 304b are fixedly connected to the corresponding rotating rods 304.

[0039] A mounting plate 301 is fixedly provided on the lower wall of the U-shaped plate 303. The mounting plate 301 is fixedly connected to the box body 201. A three-way pipe 302 is fixedly provided on the rear wall of the filter box 305. The other two ends of the three-way pipe 302 are fixedly connected to the upper wall of the U-shaped plate 303 and the mounting plate 301, respectively. The above arrangement allows debris and lint to pass through the three-way pipe 302 and enter the interior of the filter box 305.

[0040] The upper wall of the filter box 305 is fixedly provided with a box cover 305a. The box cover 305a is removable, which facilitates the cleaning of debris and lint inside the filter box 305 and also facilitates the replacement of the filter plate 308. The left and right sides of the rear wall of the filter plate 308 are symmetrically provided with limiting strips 305b to limit the filter plate 308. The limiting strips 305b are fixedly connected to the filter box 305.

[0041] Furthermore, such as Figure 5 As shown in this view, in order to prevent debris and lint from falling into the box 201 during cleaning, the debris removal motor 307 drives the corresponding rotating rod 304 to rotate counterclockwise.

[0042] The operation process of this embodiment is as follows: When dyeing the knitted fabric body 1, the negative pressure fan 306 and the impurity removal motor 307 are activated. The impurity removal motor 307 drives the rotating rod 304 to rotate. With the cooperation of the two gears 304b, the brush bristles 304a located on the lower side rotate counterclockwise, while the brush bristles 304a located on the upper side rotate clockwise, cleaning the impurities and lint to the left. At this time, under the operation of the negative pressure fan 306, the inside of the filter box 305 and the three-way pipe 302 are both in a negative pressure state. The impurities and lint are adsorbed by the negative pressure, pass through the three-way pipe 302 and enter the inside of the filter box 305. Under the filtration of the impurities and lint by the filter plate 308, the airflow is discharged from the filter box 305, while the impurities and lint are trapped inside the filter box 305.

[0043] All electrical appliances in this knitted fabric dyeing device are electrically connected to an external power source via conductive wires. They are all existing technologies and can be obtained through private customization or market purchase. No specific model is specified here.
