Description

Technical Field

[0001] This utility model relates to the technical field of tension constant control device for curtain fabric looms, and specifically to tension constant control device for curtain fabric looms. Background Technology

[0002] The tension constant control device for tire cord fabric looms is a core piece of equipment that ensures stable yarn or fabric tension during the weaving process, prevents yarn breakage / slack, and ensures uniform fabric density. It collects yarn / fabric tension signals in real time through tension sensors, and the controller calculates the deviation through an algorithm and drives a servo motor to adjust the speed of the tension roller or a magnetic powder brake to control the braking force. This dynamically offsets tension fluctuations caused by factors such as changes in weaving speed and differences in yarn material, thus meeting the production requirements of high strength and high uniformity of tire cord fabric.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology: The tension rollers of the tension constant control device in a typical tire cord weaving machine are usually not easy to disassemble, requiring workers to use auxiliary tools for disassembly. This increases the time required for disassembly, thereby reducing the effective operating rate of the equipment and affecting production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a constant tension control device for tire cord weaving machines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tension constant control device for a tire cord weaving machine, comprising a support base, with first fixing blocks fixedly connected to both sides of the top end of the support base, a conveying roller rotatably connected between the first fixing blocks, one end of the conveying roller being connected to the output shaft of a first motor, a fixing frame fixedly connected to the middle of the top of the support base, a lifting assembly installed on the lower inner surface of the support base, an adjusting assembly installed inside the lifting assembly, second fixing blocks fixedly connected to both sides of the other top end of the support base, a take-up roller rotatably connected between the second fixing blocks, one end of the take-up roller being connected to the output shaft of a second motor, and a controller installed on one end of the upper inner surface of the support base.

[0006] The lifting assembly includes an oil pump installed on the lower inner surface of the support base and a hydraulic cylinder installed on the upper inner surface of the support base. The oil pump and the hydraulic cylinder are connected by an oil supply pipe. A piston rod is provided on the inner top of the hydraulic cylinder. A mounting bracket is installed on the top of the piston rod. Limit blocks are fixedly connected to both ends of the mounting bracket.

[0007] The adjustment assembly includes a tension roller installed inside the mounting frame. Limiting grooves are formed at both ends of the tension roller. A spring is fixedly connected to the center of one end of the limiting groove. A support block is fixedly connected to one end of the spring. A mounting shaft is fixedly connected to one end of the support block.

[0008] The beneficial effects of this utility model are as follows: Through the elastic deformation of the spring, the support block can slide towards the inside of the limiting groove, so that one end of the mounting shaft is flush with both ends of the tension roller. Then, the mounting shaft is aligned with the mounting hole and inserted vertically downwards. When the mounting shaft is flush with the mounting hole, the spring will undergo elastic deformation, so that the mounting shaft enters the mounting hole, thereby completing the quick installation process. Conversely, the disassembly process can be performed. The entire process can be completed without the aid of auxiliary tools, which reduces labor and saves time costs, and also increases the effective operating rate of the equipment, thereby improving production efficiency.

[0009] To enable the collection of material pressure values: Further configuration: The tension roller is equipped with a pressure sensor, which is electrically connected to the controller, and the pressure sensor is connected in series with the oil pump.

[0010] By adopting the above technical solution, the pressure sensor can collect the pressure value of the material in real time, and then transmit it to the controller via wireless signal. The controller can then make a judgment based on the preset value, thereby starting the oil pump, which in turn drives the piston rod to adjust the height through hydraulic oil.

[0011] To ensure that the first motor and the second motor can be used effectively: The configuration is further defined as follows: the first motor and the second motor are respectively mounted on one end of the first fixed block and the second fixed block.

[0012] By adopting the above technical solution, the first motor and the second motor can be respectively installed at one end of the first fixed block and the second fixed block, thereby providing support for the first motor and the second motor.

[0013] To achieve the adjustment of material tension: Further configuration: the piston rod vertically penetrates the top center of the support base and the inner side of the fixed frame, and the piston rod and the mounting frame form a transmission structure through the cooperation of the oil pump, oil supply pipe and hydraulic cylinder, and the inner two ends of the fixed frame are provided with grooves that are consistent with the external dimensions of the limiting block.

[0014] By adopting the above technical solution, the oil pump is started, allowing hydraulic oil to enter the hydraulic cylinder through the oil supply pipe. The hydraulic oil then pushes the piston rod out of the hydraulic cylinder, causing the piston rod to move the mounting frame vertically upward. This reduces the pressure of the tension roller on the material when the tension is too high, and increases the pressure of the tension roller on the material when the tension is too low. This allows for tension control. Furthermore, the limiting block slides within the groove during the movement of the mounting frame, ensuring stability during movement.

[0015] To enable quick installation and removal of the tension roller: Further configuration: the inner dimension structure of the limiting groove is consistent with the outer dimension structure of the support block, and the spring and the support block form an elastic structure.

[0016] By adopting the above technical solution, the spring deformation causes the support block to slide inward into the limiting groove, thereby making one end of the mounting shaft flush with both ends of the tension roller. Then, the mounting shaft is aligned with the mounting hole and inserted vertically downward. When the mounting shaft is flush with the mounting hole, the spring will undergo elastic deformation, allowing the mounting shaft to enter the mounting hole, thus completing the rapid installation process. Conversely, the disassembly process can be performed, reducing labor and saving time costs.

[0017] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0022] The lifting assembly 6 includes an oil pump 601 installed on the lower inner surface of the support base 1 and a hydraulic cylinder 602 installed on the upper inner surface of the support base 1. The oil pump 601 and the hydraulic cylinder 602 are connected by an oil supply pipe 603. A piston rod 604 is provided on the inner top of the hydraulic cylinder 602.

A mounting shaft 705 is fixedly connected to one end of the support block 704.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, the tension roller 701 is equipped with a pressure sensor inside, and the pressure sensor is electrically connected to the controller 11, and the pressure sensor is connected in series with the oil pump 601.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, the first motor 4 and the second motor 10 are respectively installed at one end of the first fixing block 2 and the second fixing block 8.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the piston rod 604 vertically penetrates the top center of the support base 1 and the inner side of the fixing frame 5.

[0028] The computer software involved in the hardware carriers such as the first motor in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0029] Therefore, the "first motor," "second motor," etc. involved in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of the tension constant control device for the curtain fabric weaving machine of this application, so as to solve the corresponding technical problems to be solved by this application.

[0030] The working process of this tension constant control device for the curtain fabric weaving machine is as follows: First, press the mounting shafts 705 at both ends of the tension roller 701. The spring 703 will then elastically deform, causing the support block 704 to slide inwards towards the limiting groove 702. Stop pressing when one end of the mounting shaft 705 is flush with one end of the tension roller 701. Continue pressing. Then, place the tension roller 701 between the mounting brackets 605 and move it vertically downwards. Release the pressure when the mounting shaft 705 is inside the mounting bracket 605. One end of the mounting shaft 705 will then fit against the inside of the mounting bracket 605. When the mounting shaft 705 aligns with the mounting hole of the mounting bracket 605, the spring 703 will elastically deform. This allows the support block 704 to slide outwards from the limiting groove 702, causing one end of the support block 704 to fit against the inner side of the mounting bracket 605. At this point, the mounting shaft 705 will also fully enter the mounting hole, thus completing the installation process. Next, the material is passed over the conveyor roller 3, then under the tension roller 701, and finally over the take-up roller 9. At this point, the first motor 4 and the second motor 10 can be activated. The first motor 4 and the second motor 10 will drive the conveyor roller 3 and the take-up roller 9 to rotate respectively, thus enabling the material feeding and take-up process. During the take-up process, the pressure sensor (model: MCL-T41)... The system collects the material pressure value in real time and transmits it to the controller 11 (model: STC89C52) via wireless signal. The controller 11 then determines the value based on preset values ​​and starts the oil pump 601 (model: PV063R1K1T1NMMC). When the material pressure is too high, hydraulic oil enters the hydraulic cylinder 602 (model: HSG-KF100 / 63-500) through the oil pipe 603. This hydraulic oil pushes the piston rod 604 out of the hydraulic cylinder 602, causing the piston rod 604 to move the mounting bracket 605 vertically upward, thereby reducing the pressure of the tension roller 701 on the material. When the tension is too low, the piston rod 604 drives the mounting bracket 605 to move vertically downward, thereby increasing the pressure of the tension roller 701 on the material and thus controlling the tension. During the movement of the mounting bracket 605, the limiting block 606 will slide in the groove to ensure stability during movement. When it is necessary to disassemble the tension roller 701, press the mounting shafts 705 at both ends of the tension roller 701. At this time, the spring 703 will undergo elastic deformation, causing the support block 704 to slide inward to the inside of the limiting groove 702. At this time, the mounting shaft 705 will slowly disengage from the mounting hole of the mounting bracket 605. When it is completely disengaged, the disassembly process is completed.
