Description

Technical Field

[0001] The utility model belongs to the field of textile machine feeding devices, in particular to a textile machine feeding device which can automatically adjust the tension. Background Art

[0002] As an important part of the traditional manufacturing industry, the textile industry has a long history and profound cultural heritage. From ancient manual weaving to modern mechanized and automated production, the textile industry has undergone tremendous changes and development. With the continuous advancement of science and technology and changes in market demand, the textile industry is also constantly innovating and upgrading to adapt to the needs of the development of the times.

[0003] Feeding is a key link in textile production. It refers to the process of feeding raw materials or semi-finished products into processing equipment or machines during the production process. The accuracy and stability of feeding directly affect the quality and production efficiency of textile products. Therefore, in textile production, the feeding link has received great attention and concern.

[0004] Some traditional textile machine feeding devices on the market today are only equipped with single-channel feeding devices. Such devices can usually only process yarns one by one, and adjust the tension of the corresponding textile yarns through a tensioning wheel, that is, only one type of yarn can be transported at a time. However, when blending is required, such a single-channel feeding device is difficult to meet the feeding tension requirements of different yarns. Therefore, it is necessary to propose a textile machine feeding device that can automatically adjust the tension, which can feed multiple yarns and automatically adjust the feeding tension of the corresponding yarns. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a textile machine feeding device that can automatically adjust the tension. Through the cooperation between the tension detection component, the tension adjustment component and the guide roller, yarns of different types or specifications can be fed and the tension required for different textile yarns during the feeding process can be automatically adjusted.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: a feeding device for a textile machine that can automatically adjust the tension includes a main body and a controller, a conveying cavity is opened on the main body, an image sensor is fixedly connected to the top wall of the conveying cavity, the output end of the image sensor is signal-connected to the input end of the controller, a plurality of guide rollers for guiding yarns are arranged in the conveying cavity, a plurality of annular grooves are arranged in an array on the surface of the guide rollers, and the annular grooves are all V-shaped grooves, a plurality of tension adjustment components corresponding to the annular grooves and controlled by the controller are fixedly connected to the bottom wall of the conveying cavity, a tension detection component controlled by the controller is fixedly connected in the conveying cavity, and a combing component is fixedly connected to the bottom of the conveying cavity.

[0007] The principle of the basic scheme is: guide the yarn in the conveying cavity to form a preset conveying path through the guide roller and the tension detection component, detect the tension of the corresponding yarn through the tension detection component, collect the tension of the yarn through the image sensor, control the movement of the tension adjustment component based on the preset yarn tension range through the controller, change the tension of the yarn on the corresponding conveying path through the tension adjustment component, and separate the yarns on different conveying paths through the combing component.

[0008] The beneficial effects of the basic scheme are: 1. When blending, it is necessary to convey yarns of different specifications or types. The yarns are guided by the annular grooves on the guide rollers to form different conveying paths, and the annular grooves reduce the possibility of entanglement between different yarns; each conveying path has a corresponding tension adjustment component, so that the tension adjustment between different yarns does not interfere with each other, so as to improve the accuracy of tension adjustment;

[0009] 2. The design of the tension detection component can detect the tension of yarns on different conveying paths at the same time without interfering with each other, thereby improving the accuracy of tension adjustment;

[0010] 3. The design of the combing component further separates the yarns to ensure that yarns of different specifications or types will not get entangled when entering the next process, thereby improving the stability of feeding;

[0011] 4. The design of the image sensor can capture images of yarns on different conveying paths, and then the controller can judge the tension of the yarns on different paths based on these image analyses, thereby accurately controlling the tension adjustment component to adjust the tension, thereby improving the stability of feeding and reducing the burden on operators.

[0012] Furthermore, the tension adjustment assembly includes a plurality of electrically-controlled lifting rods corresponding to the annular grooves, the bottoms of the electrically-controlled lifting rods are fixedly connected to the bottom wall of the conveying cavity, the tops of the electrically-controlled lifting rods are fixedly connected to concave supports, the concave supports are rotatably connected to tensioning wheels, and the tensioning wheels are located in the grooves of the concave supports, and the input ends of the electrically-controlled lifting rods are signal-connected to the output ends of the controller.

[0013] The beneficial effect of the basic scheme is: by rising or falling of the electrically controlled lifting rod, the concave support and the tensioning wheel are driven to rise or fall, and then the conveying path corresponding to the tensioning wheel is changed through the tensioning wheel to adjust the tension of the corresponding yarn, thereby improving the stability of feeding.

[0014] Furthermore, the tension detection assembly includes a support rod, both ends of which are fixedly connected to both sides of the conveying cavity, and a number of tension sensors corresponding to the annular grooves are rotatably connected to the support rod, and the output end of the tension sensor is signal-connected to the input end of the controller.

[0015] The beneficial effect of the basic scheme is that through the tension sensors corresponding to different conveying paths on the support rod, the tension of the yarns corresponding to these conveying paths can be detected and the possibility of mutual interference can be reduced, thereby improving the stability of feeding different yarns at the same time.

[0016] Furthermore, the combing assembly includes a first combing plate fixedly connected to the bottom wall of the conveying cavity, a second combing plate is hingedly connected to the top of the first combing plate along the width direction of the first combing plate, a plurality of first grooves corresponding to the annular grooves are opened on the top of the first combing plate along the width direction of the first combing plate, and a plurality of second grooves corresponding to the first grooves are opened on the bottom of the second combing plate along the width direction of the second combing plate.

[0017] The beneficial effect of the basic solution is that yarns of different specifications or types are separated by a plurality of first grooves and second grooves corresponding to the first grooves one by one, thereby reducing the possibility of entanglement of these yarns and improving the stability of feeding.

[0018] Furthermore, a buckle and a buckle seat matched with the buckle are fixedly connected to one side of the width of the first combing plate and the second combing plate respectively.

[0019] The beneficial effect of the basic solution is that through the cooperation of the buckle and the buckle seat, it is convenient for the staff to operate the opening and closing between the first carding plate and the second carding plate, thereby facilitating the placement of the yarn and ensuring the stability of the feeding.

[0020] Furthermore, sponge layers are bonded inside the first arc-shaped groove and the second arc-shaped groove.

[0021] The beneficial effects of the basic solution are: the design of the sponge layer can prevent the yarn from directly contacting the first carding plate and the second carding plate to reduce wear, and at the same time, it can clean the fluff or dust on the surface of the yarn when the yarn rubs against the sponge layer.

[0022] Furthermore, the bottoms of the V-shaped grooves are all arc-shaped.

[0023] The beneficial effect of the basic solution is that the bottom of the V-shaped groove is designed to be arc-shaped, which can reduce the possibility of the textile yarn being stuck at the bottom of the groove and causing the yarn to break.

[0024] Furthermore, both the first groove and the second groove are semicircular grooves, and the first groove cooperates with the corresponding second groove to form corresponding circular combing holes.

[0025] The beneficial effect of the basic solution is that the first groove and the second groove are both designed as semicircular grooves, which can reduce the possibility of the yarn being stuck in the gap between the first carding plate and the second carding plate, thereby ensuring normal yarn transportation.

[0026] Furthermore, a plurality of universal wheels are provided at the bottom of the main body.

[0027] The beneficial effect of the basic solution is that the device can be easily moved to different positions through the universal wheels, thereby improving flexibility.

[0028] Furthermore, the image sensor and the combing component are respectively close to both ends in the width direction of the main body.

[0029] The beneficial effect of the basic solution is that placing the image sensor and the combing component close to the two ends of the width direction of the main body can reduce the possibility that the combing component interferes with the normal operation of the image sensor when the image sensor is close to the combing component, thereby improving the feeding stability.

DETAILED DESCRIPTION

[0035] The following is further described in detail through specific implementation methods:

[0036] Embodiment 1:

[0037] Basically as attached Figure 1 , Figure 2 , Figure 3 and Figure 4As shown: A feeding device for a textile machine capable of automatically adjusting tension comprises a main body 1 and a controller, wherein a conveying cavity is provided on the main body 1, an image sensor 2 is screwed to the top wall of the conveying cavity, an output end of the image sensor 2 is signal-connected to an input end of the controller, a plurality of guide rollers 3 for guiding yarns are provided in the conveying cavity, both ends of the guide rollers 3 are rotatably connected to the two side walls of the conveying cavity respectively, a plurality of annular grooves 12 are arranged in an array on the surface of the guide rollers 3 and the annular grooves 12 are all V-shaped grooves, a plurality of tension adjusting components corresponding to the annular grooves 12 controlled by the controller are threadedly connected to the bottom wall of the conveying cavity, a tension detection component controlled by the controller is bolted to the inside of the conveying cavity, and a combing component is bolted to the bottom of the conveying cavity.

[0038] The tension adjustment assembly includes a plurality of electrically controlled lifting rods 5 corresponding to the annular groove 12. The bottom of the electrically controlled lifting rods 5 are fixedly connected to the bottom wall of the conveying cavity. The top of the electrically controlled lifting rods 5 are fixedly connected to a concave support 6. The concave support 6 is rotatably connected to a tensioning wheel 8, and the tensioning wheel 8 is located in the groove of the concave support 6. The input end of the electrically controlled lifting rod 5 is connected to the signal of the output end of the controller.

[0039] The tension detection assembly includes a support rod 13, both ends of which are fixedly connected to the two sides of the conveying cavity, and a plurality of tension sensors 4 corresponding to the annular grooves 12 are rotatably connected to the support rod 13, and the output end of the tension sensor 4 is connected to the controller input end signal.

[0040] The combing assembly includes a first combing plate 9 fixedly connected to the bottom wall of the conveying cavity, a second combing plate 10 is hingedly connected to the top of the first combing plate 9 along the width direction of the first combing plate 9, a plurality of first grooves 14 corresponding to the annular grooves 12 are opened on the top of the first combing plate 9 along the width direction of the first combing plate 9, and a plurality of second grooves 11 corresponding to the first grooves 14 are opened on the bottom of the second combing plate 10 along the width direction of the second combing plate 10.

[0041] The specific implementation process is as follows: when conveying yarns of different types or specifications, the yarns are first guided by the guide roller 3, the tension sensor 4, the first combing plate 9 and the second combing plate 10 to form corresponding yarn conveying paths, and then the types and specifications of the yarns corresponding to these conveying paths are input into the controller, and the controller analyzes and obtains the appropriate conveying tension range of the corresponding yarns, wherein the controller model is preferably the Raspberry Pi all-in-one machine of HMI3010-070C-0000; then the conveying is started, so that the yarn begins to be tensioned, and at the same time, the image of the conveyed yarn is obtained through the image sensor 2 and the image information is transmitted to the controller, and the controller analyzes the real-time quantity information of the conveyed yarn, wherein the image sensor 2 model is preferably the MV-CU060-10GM Hikvision industrial camera, and at the same time, the yarns on different conveying paths have corresponding tension sensors 4 to monitor the tension of these yarns in real time and transmit the tension information to the controller, wherein the tension sensor 4 model is preferably the JZHL-M1 tension sensor 4, and then the controller controls the movement of the electric lifting rod 5 based on the above-mentioned appropriate conveying tension range of different yarns.

[0042] When it is necessary to increase the tension of the yarn on a certain conveying path, the controller controls the corresponding electric-controlled lifting rod 5 to rise. Since the top of the electric-controlled lifting rod 5 is fixedly connected to the concave support 6, and the concave support 6 is rotatably connected to the tensioning wheel 8, and the tensioning wheel 8 is located in the groove of the concave support 6, when the electric-controlled lifting rod 5 rises, the concave support 6 and the tensioning wheel 8 both rise. At the same time, since the above-mentioned conveying path is within the movement trajectory of the tensioning wheel 8, when the tensioning wheel 8 rises, a certain section of the yarn corresponding to the tensioning wheel 8 in the above-mentioned conveying path will be squeezed, thereby changing the angle between the section of yarn and the two adjacent guide rollers 3, thereby increasing the tension of the yarn on the conveying path; otherwise, the electric-controlled lifting rod 5 is controlled to descend by the controller, thereby reducing the tension of the yarn on the conveying path.

[0043] At the same time, during the conveying process, different yarns may be entangled with each other. The annular groove 12 on the surface of the guide roller 3 can limit the left and right movement of the yarn, thereby reducing the possibility of entanglement between different yarns. At the same time, in order to further reduce the entanglement of the yarn, when discharging the material, the first groove 14 on the first combing plate 9 and the second groove 11 on the second combing plate 10 cooperate to form different yarns respectively confined in the corresponding first groove 14 or second groove 11, thereby further improving the feeding stability.

[0044] Embodiment 2:

[0045] The difference from the above embodiment is that, as shown in the attached Figure 3 As shown, a buckle and a buckle seat matching the buckle are fixedly connected to the first combing plate 9 and the second combing plate 10 at one side away from the hinge.

[0046] The specific implementation process is as follows: because the first combing plate 9 is hinged to the second combing plate 10, the second combing plate 10 can rotate around the hinge, and the staff can limit the rotation of the second combing plate 10 through the buckle and the buckle seat matching the buckle, so that the bottom of the second combing plate 10 fits with the top of the first combing plate 9. At the same time, it is convenient for the staff to control the opening and closing between the first combing plate 9 and the second combing plate 10, and then it is convenient to place the yarn to be spun in the corresponding first groove 14, thereby reducing the burden on the staff and improving the feeding efficiency.

[0047] Embodiment 3:

[0048] The difference from the above embodiment is that, as shown in the attached Figure 1 As shown, sponge layers are bonded inside the first groove 14 and the second groove 11 .

[0049] The specific implementation process is as follows: when feeding, when the yarn rubs against the sponge layer in the first groove 14 and the second groove 11, part of the fluff or dust on the surface of the yarn can be cleaned off, and the bonded sponge layer is also easy to replace with a new sponge layer.

[0050] Embodiment 4:

[0051] The difference from the above embodiment is that, as shown in the attached Figure 4 As shown, the bottom of the V-shaped groove is arc-shaped to ensure stable feeding.

[0052] The specific implementation process is as follows: when the guide roller 3 rotates, the yarn will move to the bottom of the V-shaped groove. The bottom of the V-shaped groove is arc-shaped, which can reduce the possibility of the textile yarn being stuck at the bottom of the groove and causing the yarn to break, thereby improving the feeding stability.

[0053] Embodiment 5:

[0054] The difference from the above embodiment is that, as shown in the attached Figure 3 As shown, the first groove 14 and the second groove 11 are both semicircular grooves, and the first groove 14 cooperates with the corresponding second groove 11 to form corresponding circular combing holes.

[0055] The specific implementation process is as follows: during the yarn conveying process, the yarn may vibrate to a certain extent and touch the inner wall of the combing hole. Since the combing hole is formed by the cooperation of the first groove 14 and the second groove 11, and the first groove 14 and the second groove 11 are both semicircular grooves, the inner wall of the combing hole is relatively flat, thereby reducing the possibility of the yarn getting stuck in the gap between the first combing plate 9 and the second combing plate 10, thereby ensuring stable feeding.

[0056] Embodiment 6:

[0057] The difference from the above embodiment is that, as shown in the attached Figure 1As shown, a plurality of universal wheels 7 are provided at the bottom of the main body 1 to facilitate the movement of the device.

[0058] The specific implementation process is as follows: when the device needs to be moved to a different position, the universal wheel 7 can facilitate the staff to move the device. After reaching the position, the universal wheel 7 is locked by the brake pad provided by the universal wheel 7 to prevent the universal wheel 7 from continuing to move, thereby improving the flexibility of the device.

[0059] Embodiment 7:

[0060] The difference from the above embodiment is that, as shown in the attached Figure 1 As shown, the image sensor 2 and the second combing plate 10 are respectively close to both ends of the body 1 in the width direction.

[0061] The specific implementation process is as follows: the image sensor 2 and the second combing plate 10 are respectively placed close to the two ends of the width direction of the main body 1, thereby reducing the possibility that the second combing plate 10 blocks the image sensor 2 from capturing images, thereby ensuring the accuracy of image capture and the accuracy of subsequent tensioning degree judgment, and ultimately ensuring the stability of feeding.
