Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, in particular to a double-opening loom. Background Art

[0002] The textile machinery field is currently divided into two major technical routes: jacquard machines and dobby machines. Jacquard machines are widely used in high-end fabric production due to their precise pattern control capabilities, but their low production efficiency and high operating costs have long restricted the development of the industry. Dobby machines achieve high-efficiency production through multi-axis parallel technology, but there are obvious limitations in the complexity of patterns. In recent years, the market demand for textile equipment with both high-complexity patterns and high efficiency has been growing, but existing technologies are difficult to meet both types of demands at the same time.

[0003] Currently, the industry primarily addresses textile production needs through two independent solutions: one is the use of pure jacquard machines, such as STAUBLI's CX870 series, which achieves pattern weaving precision of 0.1mm using more than 15,000 healds, but the daily output of a single machine does not exceed 50 meters. The other is the use of dobby machines, such as the Toyota LF6200, which is equipped with 32 sets of independent rollers to achieve a daily production capacity of more than 300 meters, but only supports a maximum of eight basic texture variations. Some manufacturers attempt to combine the advantages of both by connecting equipment in series, but this leads to technical bottlenecks such as increased equipment footprint and increased energy consumption.

[0004] The existing technology has a core flaw: a single device cannot take into account both pattern complexity and production efficiency, which requires companies to invest in equipment repeatedly. Therefore, a double-opening loom is urgently needed. Summary of the Invention

[0005] The object of the present invention is to provide a double-opening loom to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a double-opening loom, comprising a loom body, a double warp beam mechanism installed inside the bottom of the loom body, a transmission mechanism movably connected to the outer side of the double warp beam mechanism, an adjustment device installed on the outer side of the double warp beam mechanism, and a control system provided on the outer side of the loom body; The double warp beam mechanism includes an upper warp beam and a lower warp beam. The upper warp beam is equipped with a jacquard mechanism, which contains no less than 18,000 independently controllable healds made of a special alloy with a wear-resistant surface treatment. The lower warp beam is equipped with a dobby mechanism with 36 sets of independent rollers. The roller surface is textured to increase friction with the warp yarn. The transmission mechanism includes a driving connecting rod, a driving heald frame, a steering gear, a transmission shaft, and a reduction box. The transmission mechanism transmits power to the multi-arm mechanism through the driving connecting rod and the driving heald frame, and the steering gear is connected to the transmission port of the multi-arm mechanism, and the power is transmitted to the upper faucet through the transmission shaft and the reduction box and then to the jacquard structure for synchronous weaving.

[0007] Preferably, the driving connecting rod is made of high-strength carbon fiber composite material, the driving heald frame adopts a modular design and can be replaced and adjusted according to weaving requirements, and the transmission shaft adopts a hollow structure and is filled with high thermal conductivity material.

[0008] Preferably, the steering gear includes a plurality of gears with different transmission ratios, and the steering gear also includes an electric adjustment device, which engages with the plurality of gears with different transmission ratios to adjust power transmission according to the complexity of the fabric pattern and production efficiency requirements.

[0009] Preferably, the adjustment device includes two tension sensors, one of which is installed with the upper warp beam, and the other is installed with the lower warp beam.

[0010] Preferably, the tension sensor adopts a high-precision piezoelectric ceramic sensor with a detection accuracy of ±0.01N. The adjustment device also includes two electric adjustment structures, and the two electric adjustment mechanisms are respectively installed on the upper warp beam and the lower warp beam, and the two electric adjustment mechanisms are respectively electrically connected to the tension sensor.

[0011] Preferably, the control system adopts PCL, the control system also includes a control panel, the control system includes a wireless port, the wireless port is connected to the cloud server, the control system is electrically connected to the electric adjustment device, and the control system is electrically connected to the tension sensor.

[0012] Preferably, it also includes a synchronous compensation device, which is installed on the loom body, installed on the double warp beam mechanism, and electrically connected to the control system. The synchronous compensation device includes a position sensor and a compensation controller, and the position sensor is installed on the jacquard mechanism and the multi-arm mechanism respectively, and the position sensor is electrically connected to the compensation controller.

[0013] Preferably, the position sensor uses a high-precision encoder to monitor the movement positions of the two, with a detection accuracy of ±0.001mm. The compensation controller is installed with the control system. The compensation controller receives data fed back by the position sensor and derives the compensation amount by comparing the movement position deviations of the two.

[0014] Preferably, the synchronous compensation device also includes a compensation actuator, which is installed with the double warp beam mechanism, and is electrically connected to the control system. The compensation actuator performs real-time fine-tuning of the movement of the upper warp beam jacquard mechanism and the lower warp beam multi-arm mechanism through an electric push rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects: First, in the present invention, the driving connecting rod is made of high-strength carbon fiber composite material, which reduces weight and energy loss while ensuring structural strength. The modular design of the driving heald frame is convenient for rapid replacement and adjustment according to different weaving requirements, thereby improving production flexibility and efficiency. The hollow structure of the transmission shaft is filled with high thermal conductivity material to effectively dissipate heat and ensure stable operation of the transmission system. The new lubrication system of the reduction gear can automatically adjust the flow of lubricating oil according to the operating conditions, thereby extending the service life of the equipment and reducing maintenance costs. The steering gear includes multiple gears with different transmission ratios, and the electric adjustment device is engaged with the gears. The transmission ratio is switched in real time through electric control. The power transmission is flexibly adjusted according to the complexity of the fabric pattern and the production efficiency requirements, making the weaving process more efficient and precise. Through the collaborative structure of the upper warp beam jacquard and the lower warp beam dobby, the high-complexity pattern weaving of the jacquard machine and the high-efficiency production characteristics of the dobby machine are simultaneously realized on a single device, breaking through the functional singleness limitation of traditional equipment.

[0016] Second, in the present invention, the tension sensor is used to detect slight changes in the warp tension when the upper and lower warp beams are working. During the weaving process, slight fluctuations in the warp tension may affect the quality of the fabric. The two electric adjustment mechanisms are electrically connected to the corresponding tension sensors. When the tension sensor detects that the warp tension deviates from the set range, the signal is immediately transmitted to the electric adjustment mechanism to achieve rapid response adjustment. At the same time, the tension sensor and the electric adjustment device are connected to the control system at the same time, and the electric adjustment mechanism can be operated on the control panel, and the tension data at this time can be displayed in real time. Among them, the cloud server can record the data and specific implementation at this moment in real time to facilitate subsequent viewing by the staff. The control system is electrically connected to the electric adjustment device and the tension sensor to achieve real-time data interaction. The tension sensor transmits the detection data to the control system. After analysis and processing, the control system sends adjustment instructions to the electric adjustment device to form a closed-loop control system to ensure that the warp tension is always in the best state.

[0017] Third, the present invention, the synchronous compensation device is tightly installed with the loom body and the double warp beam mechanism, and is electrically connected to the control system to form a complete signal transmission link. A high-precision encoder is used as a position sensor, and its detection accuracy reaches ±0.001mm. Under the high-speed operation and complex weaving environment of the loom, this high-precision encoder can accurately capture the subtle changes in the movement position of the jacquard mechanism and the multi-arm mechanism, providing accurate data support for synchronous compensation. The position sensors are respectively installed on the jacquard mechanism and the multi-arm mechanism to directly monitor the movement positions of the two. The jacquard mechanism is responsible for weaving complex patterns, and the multi-arm mechanism is responsible for warp yarn opening control. The synchronization of the two movements directly affects the quality of the fabric. The position sensor monitors in real time to ensure that the control system can grasp the position deviation of the two in a timely manner. The compensation controller is installed with the control system. It receives feedback data from the position sensor, compares the motion position deviation of the jacquard mechanism and the dobby mechanism through the built-in algorithm, accurately calculates the compensation amount, and uses the electric push rod drive mode of the compensation actuator to perform real-time fine-tuning of the upper warp beam jacquard mechanism and the lower warp beam dobby mechanism motion through the electric push rod. The electric push rod has the advantages of fast response speed, high adjustment accuracy, and good stability. It can quickly and accurately execute the compensation controller instructions to achieve fine adjustment of the position of the jacquard mechanism and the dobby mechanism. When the loom is running at high speed, the jacquard mechanism and the dobby mechanism are prone to position deviation, resulting in fabric pattern misalignment, uneven warp opening and other problems. The synchronous compensation device monitors and compensates the position deviation of the two in real time, controls the synchronization error within a very small range, effectively improves the fabric pattern accuracy and warp opening uniformity, and reduces the defective rate.
