Description

Technical Field

[0001] This utility model relates to the field of yarn conveying technology, specifically a device that allows multiple yarns to be fed in simultaneously. Background Technology

[0002] Yarn is a continuous linear material made from various textile fibers (such as cotton, wool, and synthetic fibers) through processes such as twisting and doubling. It possesses specific fineness, strength, and softness. It serves as an intermediate material connecting fibers and fabrics, and is widely used in the weaving of woven fabrics, knitted fabrics, embroidery, and other fields. During yarn production, a yarn feeding device is required to transport multiple yarns to ensure that they do not interfere with each other.

[0003] For example, a Chinese patent publication, CN220866809U, describes a device for simultaneously feeding multiple yarns, which includes: "A base plate with two supports fixed to its top. A first yarn roller is rotatably connected between the inner walls of both sides of the supports via bearings. This invention, by setting up a base plate, supports, fixing holes, a first yarn roller, a rotating shaft, gears, an L-shaped plate, teeth, a cleaning plate, and a cleaning cloth, allows for the simultaneous feeding of multiple yarns. The cleaning plate and cleaning cloth remove lint and other debris adhering to the surface of the yarns, ensuring cleanliness and facilitating subsequent processing. By setting up a support plate, a second yarn roller, a horizontal plate, a cylinder, a U-shaped plate, and a third yarn roller, the cylinder drives the third yarn roller up and down to adjust the tension of the yarns, preventing yarn breakage or slack during feeding."

[0004] Through a search of the aforementioned publicly available technologies, we found that this type of device, capable of simultaneously transmitting multiple yarns, still has certain drawbacks:

[0005] Before simultaneously transmitting multiple yarns, each yarn must be pulled and placed one by one into the aligned rollers. Since there are multiple yarns, it is tedious for staff to pull and place each yarn into its corresponding position one by one. Furthermore, after the yarns in the previous sequence are placed, when pulling subsequent yarns, the yarns may be accidentally moved from their original positions due to staff mishaps. In this case, the yarns that have been moved need to be readjusted, which ultimately makes it difficult to start the simultaneous transmission of multiple yarns quickly and affects the transmission efficiency. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a device for simultaneously feeding multiple yarns, comprising a base, with support plates fixed on both sides of the top of the base, and multiple sets of yarn wheel assemblies arranged between the two support plates; a lifting plate is arranged between the tops of the left and right sides of the two support plates, and a fixed frame is fixed between the tops of the two lifting plates; a guide block driven by a servo motor is slidably connected to the bottom of the fixed frame, an electric push rod is installed at the bottom of the guide block, and a movable frame is fixed to the bottom of the power output shaft of the electric push rod; a yarn wheel assembly is arranged inside the movable frame.

[0008] As a further embodiment of this utility model: the first thread reel assembly includes a first rotating rod and a first thread reel, the first rotating rod is rotatably connected between two support plates, and multiple first thread reels are equally spaced on the first rotating rod.

[0009] As a further embodiment of this utility model: the multiple sets of the thread reel assemblies are far apart from each other, and the thread reels on each rotating rod correspond to each other.

[0010] As a further embodiment of this utility model: the second thread wheel assembly includes a second rotating rod and a second thread wheel. The second rotating rod is rotatably connected to the inner side of the movable frame. Multiple second thread wheels are equidistantly arranged on the second rotating rod, and the positions of the multiple second thread wheels correspond to the positions of multiple first thread wheels.

[0011] As a further embodiment of this utility model: the servo motor is installed on one side of the fixed frame, and a guide groove is provided at the bottom of the fixed frame. The power output shaft of the servo motor is movably inserted into the guide groove and is connected to a lead screw. The end of the lead screw away from the power output shaft of the servo motor is rotatably connected to the inner wall of the other side of the guide groove.

[0012] As a further embodiment of this utility model: the guide movable block is slidably connected in the guide groove and threaded with the lead screw, and limit blocks are integrally formed on both sides of the guide movable block, and limit grooves are provided on both sides of the inner wall of the guide groove to facilitate the insertion and sliding of the limit blocks.

[0013] As a further embodiment of this utility model: each of the raised plates has a fixing plate fixed on both sides of its bottom, one side of the fixing plate is fixed to the support plate, and the two raised plates extend to the left and right sides of the support plate respectively through the corresponding fixing plates.

[0014] As a further embodiment of this utility model: the movable frame is located between two support plates, and the length of the movable frame is less than the distance between the two support plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] I. In this application, through the designed lifting plate, fixed frame, servo motor, movable frame, and thread wheel assembly II, multiple yarns can be easily bound simultaneously on one side of the base. Then, by moving the thread wheel assembly II, multiple yarns are simultaneously pulled to the other side of the base. This method can realize the simultaneous pulling and placement of multiple yarns into the corresponding thread wheel I, making the operation simpler and more convenient, eliminating the tedious steps of pulling multiple yarns one by one. Moreover, the simultaneous pulling and placement of multiple yarns into the corresponding positions can effectively prevent the yarns from deviating from their original positions. Ultimately, the simultaneous transmission of multiple yarns can be started quickly, ensuring the transmission efficiency of multiple yarns.

[0017] Second, in this application, after the second spool assembly completes the traction of multiple yarns, the spool assembly can be moved between any two sets of the first spool assembly. By using the downward pressure of the second spool assembly, downward pressure can be applied to the yarn on the first spool assembly, thereby adjusting the tension during the yarn transmission process, improving the stability of the yarn transmission, and enabling the yarn to be better transmitted through the simultaneous yarn feeding device.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 A device for simultaneously feeding multiple yarns includes a base 1, with support plates 2 fixed on both sides of the top of the base 1, and multiple sets of yarn wheel assemblies 3 arranged between the two support plates 2; a lifting plate 5 is arranged between the tops of the left and right sides of the two support plates 2, and a fixed frame 6 is fixed between the tops of the two lifting plates 5. The fixed frame 6 is located in the middle between the tops of the two lifting plates 5, which can ensure the stability of the fixed frame 6 and the balance and stability of the movable frame 9 connected below it. A guide movable block 602 driven by a servo motor 7 is slidably connected to the bottom of the fixed frame 6. An electric push rod 8 is installed at the bottom of the guide movable block 602, and the bottom of the power output shaft of the electric push rod 8 is fixed to the movable frame 9. A yarn wheel assembly 10 is arranged inside the movable frame 9.

[0026] Please see Figure 1 and Figure 3 In this embodiment, the thread reel assembly 3 includes a rotating rod 301 and a thread reel 302. The rotating rod 301 is rotatably connected between two support plates 2, and multiple thread reels 302 are equally spaced on the rotating rod 301. The multiple thread reel assemblies 3 are far apart from each other, and the thread reels 302 on each rotating rod 301 correspond to each other.

[0027] Specifically, multiple spools 302 can simultaneously limit the transmission of multiple yarns, and the multiple spools 302 on multiple sets of spool assemblies 3 correspond to each other, which can keep the yarns transmitted in a straight line and ensure the stability of the yarn transmission. The multiple sets of spool assemblies 3 are far apart from each other, which can facilitate the intervention of the subsequent spool assembly 2 10, and use the spool assembly 2 10 to adjust the tension of the yarns on the spool assembly 3.

[0028] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the second thread wheel assembly 10 includes a second rotating rod 1001 and a second thread wheel 1002. The second rotating rod 1001 is rotatably connected to the inner side of the movable frame 9. Multiple second thread wheels 1002 are equidistantly arranged on the second rotating rod 1001, and the positions of the multiple second thread wheels 1002 correspond to the positions of the multiple first thread wheels 302 respectively.

[0029] Specifically, multiple spools 2 1002 can simultaneously bind multiple yarns and facilitate simultaneous traction. The multiple spools 2 1002 correspond to the multiple spools 1 302 on each set of spool assembly 1 3, which allows the yarn traction on the spools 2 1002 to be easily placed into the spools 1 302, ensuring straight traction of the yarn and accurate entry into the spools 1 302.

[0030] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, the servo motor 7 is installed on one side of the fixed frame 6. The bottom of the fixed frame 6 is provided with a guide groove 601. The power output shaft of the servo motor 7 passes through the guide groove 601 and is connected to a lead screw 701. The end of the lead screw 701 away from the power output shaft of the servo motor 7 is rotatably connected to the inner wall of the other side of the guide groove 601. The guide movable block 602 is slidably connected in the guide groove 601 and threadedly sleeved with the lead screw 701. Both sides of the guide movable block 602 are integrally formed with limit blocks. Both sides of the inner wall of the guide groove 601 are provided with limit grooves to facilitate the insertion and sliding of the limit blocks.

[0031] Specifically, after the servo motor 7 starts, the rotation of its power output shaft drives the lead screw 701 to rotate. When the lead screw 701 rotates, it drives the guide block 602, which is threaded onto it, to slide in the guide groove 601. The limiting block and the limiting groove ensure the stability of the guide block 602's movement in the guide groove 601. When the guide block 602 moves, it can synchronously drive the electric push rod 8 and the movable frame 9 connected to its bottom to move, thereby driving the pulley assembly 10 in the movable frame 9 to move. The yarn bound to the second yarn assembly 10 can be simultaneously pulled from the left side to the right side of the two support plates 2 by the movement of the yarn pulley assembly 2 10, so as to achieve the purpose of simultaneous yarn feeding. When the yarn is subsequently transmitted, the electric push rod 8 can be activated to push the movable frame 9 and the yarn pulley assembly 2 10 inside it to descend, and the yarn pulley 2 1002 on the yarn pulley assembly 2 10 can be used to adjust the tension of the yarn. Thus, the yarn pulley assembly 2 10 has the effect of pulling multiple yarns and adjusting the tension of multiple yarns at the same time.

[0032] Please see Figure 1 and Figure 4 In this embodiment, each lifting plate 5 has a fixing plate 4 fixed on both sides of its bottom. One side of the fixing plate 4 is fixed to the support plate 2, and the two lifting plates 5 extend to the left and right sides of the support plate 2 respectively through the corresponding fixing plates 4.

[0033] Specifically, the lifting plate 5 is used to raise the height of the fixing frame 6 to facilitate the installation of components. The fixing plate 4 has a certain length, which allows the two lifting plates 5 to extend to the left and right sides of the support plate 2 respectively. Even if the left and right sides of the fixing frame 6 extend longer than the length of the support plate 2, it is convenient for the yarn wheel assembly 10 to be removed between the two support plates 2, which facilitates the binding and unbinding of yarn and avoids the yarn wheel assembly 10 being between the inner sides of the two support plates 2, thus affecting the operation.

[0034] Please see Figure 3 In this embodiment, the movable frame 9 is located between the two support plates 2, and the length of the movable frame 9 is less than the distance between the two support plates 2.

[0035] Specifically, the length of the movable frame 9 is shorter than the distance between the two support plates 2, so that the front and rear sides of the movable frame 9 do not contact the two support plates 2, which can ensure the stable and smooth movement of the movable frame 9.

[0036] In use: Start the servo motor 7 to drive the guide block 602 to the far left of the bottom of the fixed frame 6, and drive the thread wheel assembly 10 to pass through the left side of the two support plates 2. Then, the operator can bind multiple yarns one by one to the thread wheel 1002 (see...). Figure 4 (The binding method can be winding, knotting, etc.) After multiple yarns are bound to the multiple yarn wheels 1002, the servo motor 7 is started. The power output shaft of the servo motor 7 reverses, driving the guide block 602 to the rightmost side of the bottom of the fixed frame 6. This drives the yarn wheel assembly 10 to the right side of the two support plates 2 and out. Since multiple yarns are bound to the multiple yarn wheels 1002 on the yarn wheel assembly 10, when the yarn wheel assembly 10 moves, it can simultaneously drive multiple yarns to move, that is, enter from the left side of the two support plates 2 and exit from the right side of the two support plates 2. Since the positions of the multiple yarn wheels 1002 correspond to the multiple yarn wheels 302, the yarns on the yarn wheels 1002... Corresponding to spool 1 302, the electric push rod 8 can be activated at this time. By extending its power output shaft, the movable frame 9 is lowered, causing the movable frame 9 to drive the spool assembly 2 10 to descend, making the height of the spool assembly 2 10 lower than that of the spool assembly 1 3. During the descent of the spool assembly 2 10, the yarn bound to it can be lowered simultaneously, and the yarn enters the corresponding spool 1 302. At this time, multiple yarns enter the corresponding multiple spools 1 302. Then, the end yarns bound to the spool 2 1002 can be unbound, and the yarns can be bound to subsequent equipment for further production and processing. Finally, the effect of multiple yarns entering and being transmitted simultaneously on this device is achieved.

[0037] When multiple yarns are transmitted through this device, the operator can activate the electric push rod 8 to lift the movable frame 9 and the yarn wheel assembly 10. The servo motor 7 will then move the yarn wheel assembly 10 to the top between any two yarn wheel assemblies 10. By activating the electric push rod 8 again, the yarn wheel assembly 10 can be lowered and pressed into the transmitted yarn between the two yarn wheel assemblies 3. The downward pressure can be used to adjust the tension of the yarn, ensuring stable transmission of the yarn.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
