Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing equipment technology, and more specifically, it relates to a feeding device for a fabric roll dyeing machine. Background Technology

[0002] A fabric dyeing machine, also known as a dyeing vat or machine bar, is a flat-width intermittent dyeing device used for high-temperature and high-pressure dyeing of synthetic fiber fabrics and normal-temperature and normal-pressure dyeing of natural and blended fabrics. It is suitable for dyeing and pretreatment processes of fabrics such as silk, cotton, and synthetic fiber fabrics. The main body of the equipment consists of a guide roller, a winding roller, a dyeing vat, a gear differential mechanism, and a vat cover. The fabric is dyed on a flat width by alternating winding. The gear mechanism ensures constant linear speed and tension control as well as prevents wrinkles. The vat cover is divided into normal-temperature type and high-temperature and high-pressure type to suit the different dyeing needs of synthetic and natural fibers.

[0003] The dyeing machine uses guide rollers to transport the fabric into the dyeing vat for dyeing. However, the existing fabric may shift during the process of being transported to the dyeing vat by the guide rollers, which may cause uneven fabric winding during the subsequent winding process. This results in one side being tight and the other loose, or one side being thick and the other thin. At the same time, the fabric may wrinkle during the guiding process, leading to uneven dyeing of the fabric.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a feeding device for a fabric dyeing machine in order to solve the above-mentioned problems.

[0006] The above-mentioned technical objective of this utility model embodiment is achieved through the following technical solution: a feeding device for a fabric dyeing machine, including a dyeing frame and a dyeing cylinder located on the dyeing frame. The front and rear ends of the dyeing frame are respectively provided with a fabric guiding mechanism and a fabric rolling roller. The fabric guiding mechanism includes two support frames that slide with the dyeing frame. Two vertically distributed fabric guiding rollers are rotatably connected between the two support frames. A light sensor is provided between the two fabric guiding rollers. The light sensor is located at both ends of the fabric guiding rollers. The dyeing frame is provided with a driving mechanism for driving the support frames to slide up and down.

[0007] The present invention is further configured such that: both sides of the guide roller are rotatably fitted with a first mounting seat, one end of the first mounting seat is rotatably connected to a connecting rod, the end of the connecting rod away from the first mounting seat is rotatably connected to a second mounting seat, the second mounting seat is fixedly connected to the support frame, and a connecting rod is provided between the upper and lower first mounting seats.

[0008] The present invention is further configured such that: two threaded protrusions are symmetrically distributed on the guide roller, the two threaded protrusions rotate in opposite directions, and the threaded protrusions on the upper and lower guide rollers rotate in opposite directions.

[0009] The present invention is further configured such that: the support frame is provided with symmetrically distributed protrusions, and the dyeing frame is provided with sliding grooves that slide in cooperation with the protrusions.

[0010] The present invention is further configured such that: the driving mechanism includes a support cylinder fixedly connected to the dyeing frame, the support cylinder is located at the lower end of the support frame and the output end of the support cylinder is fixedly connected to the support frame.

[0011] The present invention is further configured such that: a PLC controller is also provided on the dyeing rack, and the PLC controller is electrically connected to the light sensor and the support cylinder.

[0012] In summary, this utility model has the following beneficial effects:

[0013] By setting a support frame that slides with the dyeing rack, the guide roller rotates with the support frame, and light sensors are set on the two guide rollers. When the fabric deviates during the guiding process, the light sensors are triggered, which causes the drive mechanism to drive the support frame to slide, so that there is a height difference between the two ends of the guide roller, causing the fabric to tilt back to the correct position, so that the roll roller can roll the fabric normally and make the two ends of the fabric on the roll roller flush.

[0014] By setting opposite spiral protrusions on the guide roller, the fabric will stretch to both ends under the action of the spiral protrusions during the guiding process, making the fabric flatter and reducing wrinkles, thus making the dyeing and rolling effects of the fabric better.

[0019] 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.

[0020] In one possible embodiment, please refer to Figure 1 and Figure 3 As shown, a feeding device for a fabric dyeing machine includes a dyeing frame 1 and a dyeing vat 2 located on the dyeing frame 1. A fabric guiding mechanism 3 and a fabric rolling roller 4 are respectively provided at the front and rear ends of the dyeing frame 1. The fabric guiding mechanism 3 conveys the fabric into the dyeing vat 2 for dyeing. The fabric rolling roller 4 then rolls up and stores the dyed fabric for the next processing step. The fabric rolling roller 4 is driven by a drive motor. The fabric guiding mechanism 3 rotates due to the movement of the fabric. The fabric guiding mechanism 3 includes two support frames 301 that slide in cooperation with the dyeing frame 1. Symmetrically distributed protrusions 3011 are provided on the support frames 301. The dyeing frame 1 is provided with a sliding groove 101 that slides in cooperation with the protrusions 3011. The sliding engagement of 3011 with the chute 101 enables the support frame 301 to slide on the dyeing rack 1. The dyeing rack 1 is provided with a drive mechanism 5 for driving the support frame 301 to slide up and down. The drive mechanism 5 includes a support cylinder 501 fixedly connected to the dyeing rack 1. The support cylinder 501 is located at the lower end of the support frame 301 and the output end of the support cylinder 501 is fixedly connected to the support frame 301. Thus, when the fabric deviates during the fabric guiding process, the drive mechanism 5 can drive the support frame 301 to slide, so that there is a height difference between the two ends of the guide roller 302, causing the fabric to tilt back to the correct position, thereby enabling the roll roller 4 to roll the fabric normally, and making the two ends of the fabric on the roll roller 4 flush.

[0021] For further details, please refer to Figure 1 and Figure 3 As shown, two guide rollers 302 are rotatably connected between the two support frames 301. The guide rollers 302 are provided with two symmetrically distributed threaded protrusions 306. The two threaded protrusions 306 rotate in opposite directions. The threaded protrusions 306 on the upper and lower guide rollers 302 rotate in opposite directions. When the fabric passes between the two guide rollers 302, the fabric will spread out to both ends under the action of the threaded protrusions 306, making the fabric more flat and reducing the wrinkles of the fabric, thereby making the dyeing and rolling effect of the fabric better.

[0022] For further details, please refer to Figure 1 and Figure 2As shown, both sides of the guide roller 302 are rotatably fitted with first mounting seats 303. One end of the first mounting seat 303 is rotatably connected to a connecting rod 304. The end of the connecting rod 304 away from the first mounting seat 303 is rotatably connected to a second mounting seat 305. The second mounting seat 305 is fixedly connected to the support frame 301. A connecting rod 307 is provided between the upper and lower first mounting seats 303. Thus, when the drive mechanism 5 drives the support frame 301 to rise, the guide roller 302 will not affect its own rotation while rising. Moreover, by setting the connecting rod 307, the distance between the two guide rollers 302 can be kept constant, ensuring the guiding effect on the fabric.

[0023] For further details, please refer to Figure 1 , Figure 2 and Figure 3 As shown, a light sensor 6 is installed between the two guide rollers 302. The light sensor 6 is located at both ends of the guide rollers 302. A PLC controller is also installed on the dyeing rack 1. The PLC controller is electrically connected to the light sensor 6 and the support cylinder 501. When the fabric deviates during the guiding process, the light sensor 6 is triggered. The output of the light sensor 6 is connected to the input of the PLC controller, and the output of the PLC controller is connected to the input of the support cylinder 501. When the PLC receives the signal from the light sensor 6, it outputs a command to the corresponding support cylinder 501. That is, the support cylinder 501 on the side that is blocked and triggered will be driven accordingly, causing the support frame 301 to slide upward, so that there is a height difference between the two ends of the guide rollers 302, causing the fabric to tilt back to the correct position. After the fabric returns to the correct position, the light sensor 6 stops outputting, so that the support cylinder 501 retracts, making the two ends of the guide rollers 302 level, so that the fabric can be fed normally and stably, and thus the fabric roll roller 4 can roll the fabric normally and stably.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
