Description

Technical Field

[0001] This utility model relates to the field of tension detection technology, and in particular to a tension detection device for warp yarn machines used in ribbon production. Background Technology

[0002] The warp tension detection device used in ribbon production is designed to monitor and control the tension borne by the warp yarns during the ribbon production process.

[0003] Chinese Patent Publication No. CN207130423U, published on March 23, 2018, discloses a tension detection device for a warp yarn machine, including a mounting bracket. A controller is mounted on one side of the mounting bracket, and a fixed electromagnet is mounted on the top of the mounting bracket. A lifting column is slidably mounted inside the mounting bracket, and a movable electromagnet is mounted on the upper end of the lifting column. A lifting frame is mounted on the lower end of the lifting column, and a rotating shaft is mounted inside the lifting frame. A guide wheel is mounted in the middle of the rotating shaft, and a tension sensor is mounted on the end of the rotating shaft. A first buffer spring and a second buffer spring are nested on the outside of the lifting column.

[0004] Existing tension detection devices for warp machines used in ribbon production attach the yarn to the top of the guide roller. During warp transmission, the fluctuation of the glass fiber causes tension changes, and the tension sensor detects the tension in real time. In practice, the base frame, rotating shaft, and guide roller form a closed space. Since the yarn cannot be attached to this closed space, pressure can only be applied downwards to the yarn, increasing the limitations of the detection device. Therefore, there is an urgent need to propose a corresponding tension detection device for warp machines used in ribbon production to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a tension detection device for warp yarn machines used in ribbon production in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tension detection device for a warp yarn machine used in ribbon production includes a mounting frame and a tension sensor. A support frame and a lifting assembly for vertically raising and lowering the support frame are integrated below the mounting frame. A base frame and a connecting assembly for connecting the base frame are integrated at the bottom of the support frame. A rotating rod is connected to the input end of the tension sensor. A guide wheel is fixedly connected to the outer wall of the rotating rod. A side frame is detachably connected to the outer wall of the base frame. A retaining sleeve is rotatably connected to the outer wall of the side frame via a bearing. The retaining sleeve is detachably connected to the open end of the rotating rod.

[0008] Preferably, the lifting assembly includes a push rod that is screwed into the inner wall of the horizontal end of the mounting frame, the open end of the push rod being rotatably connected to the top of the support frame, and a sliding plate that is slidably connected to the inner wall of the vertical end of the mounting frame being fixedly connected to the top of the support frame.

[0009] Preferably, the skateboard has an L-shaped cross-section.

[0010] Preferably, the connecting assembly includes a T-shaped frame fixedly connected to the top of the base frame, and a spring is fixedly connected between the bottom of the horizontal end of the T-shaped frame and the inner wall of the bottom of the support frame.

[0011] Preferably, a tie plate is fixedly connected to the top of the side frame, and the tie plate is fixedly connected to the top of the base frame by a locking rod.

[0012] Preferably, a protrusion is fixedly connected to the open end of the rotating rod, and the protrusion is fixedly connected to the sleeve by a fastening rod.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, after the mounting frame is installed at the corresponding position on the warp machine, the pressure direction is selected according to the site conditions. When vertical downward pressure is selected, the vertical position of the guide wheel is directly adjusted by the lifting component, and the guide wheel presses down on the top of the yarn. When vertical upward pressure is selected, the fastening rod and locking rod are separated in sequence, which can realize the separation of the side frame and the base frame, as well as the clamp and the rotating rod. At this time, the yarn can be combined above the guide wheel. After resetting the side frame and the clamp, the vertical position of the guide wheel is adjusted by the lifting component, and the guide wheel pulls the yarn up. In the subsequent warp process, whether downward or upward pressure is applied, the fluctuation of the glass fiber will cause tension changes. The tension sensor detects the tension in real time, thereby expanding the tension detection method of the warp machine and improving the applicability of the warp machine tension detection device used in webbing production.

[0015] 2. In this application, the rotating push rod is screwed into the horizontal end of the mounting frame. The push rod rotates and engages with the top of the support frame, providing traction to the support frame. The sliding plate simultaneously slides and engages with the inner surface of the vertical end of the mounting frame, thereby achieving stable vertical movement of the support frame and ensuring the stability of the vertical position adjustment of the base frame and the guide wheel.

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A tension detection device for a warp yarn machine used in ribbon production includes a mounting frame 1 and a tension sensor 8. A support frame 3 and a lifting assembly for vertical lifting of the support frame 3 are integrated below the mounting frame 1. A base frame 7 and a connecting assembly for connecting the base frame 7 are integrated at the bottom of the support frame 3. A rotating rod 9 is connected to the input end of the tension sensor 8. A guide wheel 10 is fixedly connected to the outer wall of the rotating rod 9. A side frame 11 is detachably connected to the outer wall of the base frame 7. A retaining sleeve 14 is rotatably connected to the outer wall of the side frame 11 through a bearing. The retaining sleeve 14 is detachably connected to the open end of the rotating rod 9.

[0025] After installing the mounting bracket 1 to the corresponding position on the warp machine, select the pressure direction according to the site conditions. When selecting vertical downward pressure, directly adjust the vertical position of the guide wheel 10 through the lifting component. The guide wheel 10 presses down on the top of the yarn. When selecting vertical upward pressure, separate the fastening rod 15 and the locking rod 13 in sequence to separate the side frame 11 from the base frame 7 and the clamp 14 from the rotating rod 9. At this time, the yarn can be attached to the top of the guide wheel 10. After resetting the side frame 11 and the clamp 14, adjust the vertical position of the guide wheel 10 through the lifting component. The guide wheel 10 pulls the yarn up. In the subsequent warp process, whether it is downward or upward pressure, the fluctuation of the glass fiber will cause tension changes. The tension sensor 8 detects the tension in real time, thereby expanding the detection method of warp machine tension and improving the applicability of the warp machine tension detection device used for webbing production.

[0026] It should be noted that the tension sensor 8 here uses existing technology, and its specific working mechanism and cooperation mechanism with the rotating rod 9 will not be described in detail here.

[0027] Specifically, such as Figure 2 and Figure 4 As shown, the lifting assembly includes a push rod 2 that is screwed onto the inner wall of the horizontal end of the mounting frame 1. The open end of the push rod 2 is rotatably connected to the top of the support frame 3. A slide plate 4 is fixedly connected to the top of the support frame 3 and slidably connected to the inner wall of the vertical end of the mounting frame 1. Rotating the push rod 2 causes it to screw onto the horizontal end of the mounting frame 1. The push rod 2 rotates and engages with the top of the support frame 3, providing traction to the support frame 3. Simultaneously, the slide plate 4 slides and engages with the inner wall of the vertical end of the mounting frame 1, thereby achieving stable vertical movement of the support frame 3. This ensures the stability of the vertical position adjustment of the base frame 7 and the guide wheel 10. The slide plate 4 has an L-shaped cross-section to prevent the slide plate 4 from completely detaching from the mounting frame 1.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, the connecting assembly includes a T-shaped frame 5 fixedly connected to the top of the base frame 7. A spring 6 is fixedly connected between the bottom of the horizontal end of the T-shaped frame 5 and the inner wall of the bottom of the support frame 3, thereby providing vertical flexibility for the guide wheel 10 and ensuring the bonding effect between the guide wheel 10 and the yarn. A flap 12 is fixedly connected to the top of the side frame 11. The flap 12 is fixedly connected to the top of the base frame 7 through a locking rod 13. A protrusion 16 is fixedly connected to the open end of the rotating rod 9, and the protrusion 16 and the sleeve 14 are fixedly connected through a fastening rod 15, thereby ensuring the ease of disassembling the side frame 11 from the base frame 7 and the rotating rod 9.

[0029] Working principle: After installing the mounting frame 1 to the corresponding position on the warp spinning machine, select the pressure direction according to the site conditions. When selecting vertical downward pressure, directly adjust the vertical position of the guide wheel 10 through the lifting assembly. The guide wheel 10 presses down on the top of the yarn. When selecting vertical upward pressure, sequentially separate the fastening rod 15 and the locking rod 13 to separate the side frame 11 from the base frame 7 and the clamping sleeve 14 from the rotating rod 9. At this time, the yarn can be attached to the top of the guide wheel 10. After resetting the side frame 11 and the clamping sleeve 14, adjust the vertical position of the guide wheel 10 through the lifting assembly. The guide wheel 10 pulls the yarn upward. (Further details to be added later...) During the warping process, whether pressure is applied from below or above, the fluctuation of the glass fiber will cause tension changes. Tension sensor 8 detects the tension in real time, thereby expanding the detection method of warp machine tension and improving the applicability of the tension detection device for warp machines used in ribbon production. Rotating push rod 2 makes it screw into the horizontal end of mounting frame 1. Push rod 2 rotates and cooperates with the top of support frame 3 and provides traction force to support frame 3. Slide plate 4 simultaneously slides and cooperates with the inner surface of the vertical end of mounting frame 1, thereby realizing the stable vertical movement of support frame 3, thus ensuring the stability of the vertical position adjustment of base frame 7 and guide wheel 10.

[0030] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
