Description

Technical Field

[0001] This utility model relates to the field of rapier loom technology, and more specifically to a rapier loom. Background Technology

[0002] The rapier loom is the mainstream machine among looms, known for its high speed, stability, and adaptability to various fabric types. It is the preferred machine for weaving various grades of clothing fabrics and other types of grey fabrics. Among shuttleless looms, the weft insertion principle of the rapier loom was first proposed. Initially, it used a single rapier, but later, a rapier loom with two rapiers for weft insertion was put into practical use. Currently, tire cord fabric uses high-strength yarns as warp and medium- to fine-count single yarns as weft, which are then woven on a rapier loom. The warp yarns are closely arranged, bearing almost the entire load of the tire cord, while the weft yarns are sparsely arranged, used only to connect the warp yarns and maintain their even arrangement; it is named for its resemblance to a curtain.

[0003] For example, the rapier loom with prior art disclosure number CN211897270U, ​​through a sliding take-up roller, can adjust the tension of the woven fabric, ensuring moderate tension and preventing curling, thus improving the neatness of the take-up. Simultaneously, the cleaning component can remove impurities remaining on the fabric before take-up, further improving the quality of the take-up.

[0004] However, the above-mentioned existing technology still has the following problems when used: the winding component of the rapier loom is responsible for automatically winding up the woven tire cord fabric for subsequent transfer and transportation. However, during long-term use, the winding roller will experience a decrease in flatness due to continuous friction or vibration, which can easily cause uneven tension on the fabric surface and ultimately affect the product quality of the tire cord fabric. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a rapier loom that automatically winds up woven tire cord fabric using a take-up roller. By utilizing a transmitter and receiver to detect the diameter of the take-up roller, the surface flatness of the roller can be accurately detected, facilitating machine stoppage for adjustment or component replacement. This ensures the winding quality of the tire cord fabric, prevents defective rolls from flowing into subsequent processes, and ultimately improves the production quality of tire cord fabric, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapier loom, including a frame, on which a winding assembly is fixedly mounted. The winding assembly includes a base fixed within the frame, with support plates fixed on both sides of the top of the base. A winding roller is installed between the two support plates, and a laser diameter gauge is sleeved on the outside of the winding roller. The laser diameter gauge includes a transmitter and a receiver, with nut blocks fixedly mounted at the bottom of both the transmitter and the receiver. A mounting groove is provided on the top of the base, and an adjustment assembly for adjusting the movement of the nut blocks is fixedly mounted inside the mounting groove.

[0007] In a preferred embodiment, the adjustment assembly includes a linear module fixed inside a mounting slot, an electric push rod fixedly mounted on the top of the linear module, and a sliding groove fixedly mounted on the top of the piston rod of the electric push rod.

[0008] In a preferred embodiment, a lead screw is rotatably mounted inside the slide groove. Two nut blocks are fitted onto the lead screw and threadedly connected to it. The threads of the two nut blocks and the lead screw have opposite directions, causing the two nut blocks to move in opposite directions. A first motor is fixedly mounted at the rear end of the slide groove. The front end of the output shaft of the first motor passes through the slide groove and is fixed to the lead screw. The positions of the transmitter and receiver are automatically adjusted by means of the first motor, the lead screw, and the nut blocks, eliminating the need for manual adjustment and making it very convenient to use.

[0009] In a preferred embodiment, limiting blocks are fixedly provided on both the front and rear sides of the bottom of the slide, and limiting grooves corresponding to the limiting blocks are opened on both the front and rear sides of the top of the base. The limiting blocks are located in the limiting grooves. By cooperating with the limiting grooves, the stability of the slide movement can be effectively improved.

[0010] In a preferred embodiment, each of the two support plates has a through hole on one side, and each of the two through holes has a slider. A limit roller is connected between the two sliders. The limit roller is used to limit the tire cord fabric, which can improve the stability of the winding process.

[0011] In a preferred embodiment, a hydraulic cylinder is fixedly installed on the top of each of the two support plates. The bottom end of the piston rod of the hydraulic cylinder is fixed to the top of the slider. The height of the limit roller is automatically adjusted by the hydraulic cylinder, making it easier to use.

[0012] In a preferred embodiment, a second motor is fixedly mounted on one side of the take-up roller. The second motor is fixed to the support plate. By driving the take-up roller to rotate with the help of the second motor, the tire cord fabric can be automatically rolled up, thereby improving the rolling efficiency.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention automatically winds up woven tire cord fabric using a take-up roller, and uses a linear module to drive a slide to move the transmitter and receiver horizontally. By using the transmitter and receiver to detect the diameter of the take-up roller, the surface flatness of the take-up roller can be accurately detected, making it convenient for workers to stop the machine to adjust or replace parts. This ensures the winding quality of the tire cord fabric, prevents defective rolls from flowing into subsequent processes, and thus improves the production quality of tire cord fabric.

[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] Refer to the instruction manual appendix Figures 1-5This utility model provides a rapier loom, including a frame 1, on which a winding assembly 2 is fixedly mounted. The winding assembly 2 includes a base 21 fixed inside the frame 1. Support plates 22 are fixedly mounted on both sides of the top of the base 21. A winding roller 23 is installed between the two support plates 22. A second motor 11 is fixedly mounted on one side of the winding roller 23. The second motor 11 is fixed on the support plate 22. A servo second motor 11 can be selected, which is equipped with a high-precision feedback device such as an encoder, which can monitor the operating status of the second motor 11 in real time and correct deviations, thereby improving the stability of winding.

[0026] A laser diameter measuring instrument 3 is sleeved on the outside of the take-up roller 23. The laser diameter measuring instrument 3 includes a transmitter 31 and a receiver 32. Nut blocks 33 are fixedly provided at the bottom of the transmitter 31 and the bottom of the receiver 32. An installation groove 34 is provided on the top of the base 21.

[0027] An adjustment component 4 for adjusting the movement of the nut blocks 33 is fixedly provided inside the mounting groove 34. The adjustment component 4 includes a linear module 41, which is fixed inside the mounting groove 34. An electric push rod 42 is fixedly provided on the top of the linear module 41. A slide groove 43 is fixedly provided on the top of the piston rod of the electric push rod 42. A lead screw 44 is rotatably provided inside the slide groove 43. Two nut blocks 33 are both sleeved on the lead screw 44 and threadedly connected to the lead screw 44. The threads between the two nut blocks 33 and the lead screw 44 have opposite directions of rotation, so that the two nut blocks 33 move in opposite directions. A first motor 45 is fixedly provided at the rear end of the slide groove 43. The front end of the output shaft of the first motor 45 passes through the slide groove 43 and is fixed to the lead screw 44.

[0028] In practical applications, the rapier weaving mechanism inside frame 1 automatically winds the produced tire cord fabric onto the take-up roller 23. After the take-up operation is completed and the empty take-up roller 23 is replaced, the first motor 45 drives the lead screw 44 to rotate, and the two nut blocks 33 on the lead screw 44 move synchronously to automatically adjust the distance between the transmitter 31 and the receiver 32. Then, the linear module 41 drives the slide 43 to move the transmitter 31 and the receiver 32 from left to right. During this process, the transmitter 31 emits a uniform parallel beam of light, and the take-up roller 23 traverses the beam propagation path, forming a light-blocking area (i.e., a "shadow") corresponding to the diameter of the roller body. The laser diameter gauge 3 detects light signals. Blocked areas cannot receive light, while unblocked areas are normally photosensitive, thus forming a "bright-dark-bright" light intensity distribution on the detector. Subsequently, the signal processing unit of the laser diameter gauge 3 directly calculates the diameter of the take-up roller 23 based on the number of pixels in the dark area captured by the detector and system parameters such as pixel spacing (since this is existing technology, it will not be elaborated further here). By acquiring diameter data in real time, the surface flatness of the take-up roller 23 can be accurately detected. Once an abnormality is found, the operator can immediately stop the machine to make adjustments or replace parts, thereby ensuring the winding quality of the tire cord fabric and preventing defective rolls from flowing into subsequent processes.

[0029] like Figures 1-4 As shown, limiting blocks 5 are fixedly provided on both the front and rear sides of the bottom of the slide 43, and limiting grooves 6 corresponding to the limiting blocks 5 are provided on both the front and rear sides of the top of the base 21. The limiting blocks 5 are disposed in the limiting grooves 6. By cooperating with the limiting blocks 5 and the limiting grooves 6, the stability of the slide 43 movement can be effectively improved.

[0030] like Figure 2 As shown, each of the two support plates 22 has a through hole 7 on one side, and each of the two through holes 7 has a slider 8 inside. A limit roller 9 is connected between the two sliders 8. A hydraulic cylinder 10 is fixedly installed on the top of each of the two support plates 22, and the bottom end of the piston rod of the hydraulic cylinder 10 is fixed to the top of the slider 8.

[0031] The limiting roller 9 located above the take-up roller 23 can constrain the top of the fabric surface, thereby effectively improving the flatness of the fabric surface during the winding process. At the same time, the hydraulic cylinder 10 is set to automatically adjust the height of the limiting roller 9 without manual operation, which is very convenient to use. Furthermore, the two hydraulic cylinders 10 use a flow divider valve, which distributes the flow of one pump evenly to the two hydraulic cylinders 10, so that the oil flow into / out of the two cylinders is equal, thereby achieving speed synchronization.

[0032] In actual use, the laser diameter gauge 3, linear module 41, electric push rod 42, first motor 45, hydraulic cylinder 10 and second motor 11 can all be connected to the controller on the rapier loom frame 1 for easy control. Since this is a conventional technology, it will not be described in detail here.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
