Abstract
Description
Technical Field
[0001] This utility model relates to the field of weft winding machine technology, and in particular to a tension control device for a weft winding machine. Background Technology
[0002] Currently, paper felt manufacturers have increasingly higher requirements for papermaking webs, imposing strict requirements on web tension and weave structure. This necessitates increasingly stringent weft tension control in the loop-woven web, making proper weft tension control crucial for ensuring web quality and improving production efficiency. Asymmetrical weft tension not only leads to unevenness in the web surface but can also affect the physical properties of the final product (such as strength and smoothness), and may even cause mechanical failures during production.
[0003] In related technologies, floating tension control mechanical structures are generally used in weft winding machines to adapt to yarn tension fluctuations. That is, the springs in the floating tension control mechanical structure are used to buffer the yarn tension. However, since the yarn of the weft winding machine is wound on the bobbin and moves back and forth, the yarn tension changes significantly. The above-mentioned single floating tension control mechanical structure has a small tension adjustment range and cannot adapt to the yarn tension changes, thus affecting the quality of the product. Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.
[0005] Therefore, one objective of this utility model is to provide a tension control device for a weft winding machine. By setting up a tension adjustment component, a tension detection mechanism, and a hysteresis tension wheel, the tension fluctuation of the yarn can be coarsely adjusted and finely adjusted, thereby expanding the adjustable range of tension fluctuation and enabling the device to adapt to changes in yarn tension, thus ensuring product quality.
[0006] To achieve the above objectives, the first aspect of this utility model provides a tension control device for a weft winding machine, comprising: a housing, a hysteresis tension wheel, a tension detection mechanism, and a tension adjustment assembly. A first yarn wheel is rotatably connected to the outer wall of the housing; the hysteresis tension wheel is rotatably connected to the housing; the tension detection mechanism includes a detection component and two second yarn wheels, wherein the detection component is disposed on the outer wall of the housing, and the two second yarn wheels are respectively disposed on the housing; the tension adjustment assembly includes a tension adjustment component and two limiting members, wherein the tension adjustment component is mounted on the outer wall of the housing; the two limiting members are respectively disposed on the housing, and the limiting members are located above the tension adjustment component; the first yarn wheel, the hysteresis tension wheel, the tension detection mechanism, and the tension adjustment assembly are respectively located on the same side of the housing.
[0007] In addition, the tension control device for the weft winding machine proposed above according to this utility model may also have the following additional technical features:
[0008] Specifically, the detection assembly includes a frame, a tension detection unit, a detection rod, and a detection wheel, wherein the frame is connected to the outer wall of the housing; the tension detection unit is mounted on the frame; the detection rod is mounted on the tension detection unit; and the detection wheel is rotatably mounted on the detection rod, and the detection wheel is located between the two second yarn wheels.
[0009] Specifically, the tension detection mechanism further includes a locking assembly, which includes an insert plate, a sleeve, and a locking pin. The insert plate is slidably connected to the housing. Two through slots are symmetrically formed on the outer wall of the housing. The second yarn wheel passes through the through slots and is rotatably connected to the insert plate. The sleeve is installed on the outer wall of the housing. The locking pin is inserted into the inside of the sleeve and abuts against the insert plate.
[0010] Specifically, the tension adjusting component includes an elastic reset base, a tension rod, and a guide wheel. The elastic reset base is mounted on the outer wall of the housing and is located between the two limiting members. The tension rod is connected to the elastic reset base, and the guide wheel is mounted on one end of the tension rod.
[0011] Specifically, a tension adjustment knob is installed on the housing.
[0012] Compared with the prior art, the present invention has the following beneficial effects: The tension control device of the weft winding machine of the present invention uses a tension adjustment component to coarsely adjust the tension fluctuation of the yarn, thereby reducing the tension fluctuation of the yarn. The tension detection mechanism detects the tension fluctuation of the yarn after coarse adjustment and feeds the data back to the hysteresis tension wheel. The hysteresis tension wheel finely adjusts the tension fluctuation of the yarn, thereby expanding the adjustable range of the tension fluctuation of the device, which can adapt to the tension changes of the yarn and thus ensure the quality of the product.
[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0018] The tension control device for a weft winding machine according to an embodiment of the present invention will now be described with reference to the accompanying drawings.
[0019] like Figure 1 As shown, the tension control device for a weft winding machine according to an embodiment of this utility model may include:
[0020] 1. Housing, 2. Hysteresis tension wheel, 3. Tension detection mechanism, and 4. Tension adjustment assembly.
[0021] The first yarn wheel 11 is rotatably connected to the outer wall of the housing 1, and the magnetic tension wheel 2 is rotatably connected to the housing 1.
[0022] The tension detection mechanism 3 includes a detection component 31 and two second yarn wheels 32. The detection component 31 is disposed on the outer wall of the housing 1, and the two second yarn wheels 32 are disposed on the housing 1 respectively.
[0023] The tension adjustment assembly 4 includes a tension adjustment component 41 and two limiting members 42. The tension adjustment component 41 is installed on the outer wall of the housing 1, and the two limiting members 42 are respectively disposed on the housing 1, with the limiting members 42 located above the tension adjustment component 41.
[0024] The first yarn wheel 11, the hysteresis tension wheel 2, the tension detection mechanism 3, and the tension adjustment assembly 4 are located on the same side of the housing 1.
[0025] It should be noted that multiple of these devices are installed on the weft winding machine for operation, and the number of these devices can be determined according to the actual situation.
[0026] Specifically, the yarn first passes through the first yarn wheel 11, then the yarn is wound around the hysteresis tension wheel 2, and then passes through a second yarn wheel 32, a detection component 31, another second yarn wheel 32 and a tension adjustment component 41 in sequence, thus completing the direction and control of the yarn.
[0027] The yarn is released from the external spiral tube. As the yarn reciprocates on the spiral tube, there is a certain tension fluctuation in the yarn under the traction of the other end of the yarn. The yarn passes through the first yarn wheel 11, the hysteresis tension wheel 2, a second yarn wheel 32, the detection component 31, another second yarn wheel 32, and the tension adjustment component 41. The tension adjustment component 41 can coarsely adjust the tension fluctuation of the yarn, so that the tension fluctuation of the yarn is reduced. At the same time, the limiting component 42 can limit the tension adjustment component 41 to prevent the tension adjustment component 41 from rotating excessively.
[0028] The detection component 31 measures the fluctuation of the yarn and feeds the data back to the hysteresis tension wheel 2. The hysteresis tension wheel 2 finely adjusts the tension fluctuation of the yarn, thereby expanding the adjustable range of the tension fluctuation of the device, which can adapt to the tension changes of the yarn and thus ensure the quality of the product.
[0029] In one embodiment of this utility model, such as Figure 1 As shown, the detection component 31 includes a frame 311, a tension detection unit 312, a detection rod 313, and a detection wheel 314.
[0030] The frame 311 is connected to the outer wall of the housing 1, the tension detection unit 312 is installed on the frame 311, the detection rod 313 is installed on the tension detection unit 312, and the detection wheel 314 is rotatably mounted on the detection rod 313 and is located between the two second yarn wheels 32.
[0031] It should be noted that the frame 311 described in this embodiment can be fixed to the weft winding machine by means of fasteners (e.g., bolts).
[0032] Specifically, the tension detection unit 312 may include a tension sensor and a controller. When the yarn passes through the tension detection wheel 314, the tension sensor detects the analog signal and transmits it to the external computer control device. After comparing it with the tension set by the human-machine interface, the data is transmitted to the hysteresis tension wheel 2 for real-time tension adjustment.
[0033] It should be noted that the specific structure and working principle of the hysteresis tension wheel 2 described in this embodiment have been disclosed in the prior art, so they will not be described in detail here.
[0034] In one embodiment of this utility model, such as Figure 1As shown, the tension detection mechanism 3 also includes a locking assembly 33, which includes an insert plate 331, a sleeve 332, and a locking pin 333.
[0035] The insert plate 331 is slidably connected to the housing 1. Two through slots 320 are symmetrically opened on the outer wall of the housing 1. The second yarn wheel 32 passes through the through slots 320 and is rotatably connected to the insert plate 331. The sleeve 332 is installed on the outer wall of the housing 1. The locking pin 333 is inserted into the inside of the sleeve 332 and abuts against the insert plate 331.
[0036] Specifically, the insert plate 331 can move up and down. When threading is required, the upper locking pin 333 is pulled open, and the second yarn wheel 32 can move above the detection wheel 314 (this operation can be achieved by a spring). At this time, the second yarn wheel 32 and the detection wheel 314 are separated, making it easy to thread the yarn. After threading is completed, the locking component 33 is pressed down, and the insert plate 331 is fixed by the locking pin 333. At this time, the second yarn wheel 32 and the detection wheel 314 form a wrap angle with the yarn, thereby detecting yarn tension fluctuations.
[0037] In one embodiment of this utility model, such as Figure 1 As shown, the tension adjustment component 41 includes an elastic reset base 411, a tension rod 412, and a guide wheel 413.
[0038] The elastic reset base 411 is installed on the outer wall of the housing 1 and is located between two limiting members 42. The tension rod 412 is connected to the elastic reset base 411 and the guide wheel 413 is installed at one end of the tension rod 412.
[0039] It should be noted that the elastic reset base 411 described in this embodiment may include a torsion spring and a rotating shaft. Its specific working principle and connection structure have been disclosed in the prior art, so they will not be described in detail here.
[0040] In one embodiment of this utility model, such as Figure 1 As shown, a tension adjustment knob 51 is installed on the housing 1.
[0041] It should be noted that the housing 1 described in this embodiment is provided with a rod and a worm gear transmission assembly inside. The tension adjustment knob 51 is connected to the worm gear transmission assembly, the worm gear transmission assembly is connected to the rod, and the rod is connected to the rotating shaft of the elastic reset base 411.
[0042] Specifically, when the relevant technicians rotate the tension adjustment knob 51, it can drive the shaft of the elastic reset base 411 to rotate, thereby changing the initial position of the tension rod 412, and ultimately expanding the adjustable range of the tension adjustment component 41 to cope with yarn tension fluctuations.
[0043] In summary, the tension control device for the weft winding machine of this invention uses a tension adjustment component to coarsely adjust the tension fluctuation of the yarn, thereby reducing the tension fluctuation. The tension detection mechanism detects the tension fluctuation of the yarn after coarse adjustment and feeds the data back to the hysteresis tension wheel. The hysteresis tension wheel then finely adjusts the tension fluctuation of the yarn, thus expanding the adjustable range of the tension fluctuation of this device, enabling it to adapt to changes in yarn tension, and thus ensuring product quality.
