Description

Technical Field

[0001] This invention belongs to the technical field of electronic jacquard machines, and specifically relates to a jacquard machine head with a low failure rate. Background Technology

[0002] Currently, in the jacquard weaving of cotton yarn, a large amount of highly adhesive cotton lint is generated, creating a harsh working environment with dust. The jacquard machine head is in this environment for a long time. Due to the need to repeatedly lift a large number of extremely heavy lifting devices, frequent machine shutdowns for lubrication and oiling are required. Technical problems such as wall panel deformation and ineffective dust removal lead to a high equipment failure rate.

[0003] Chinese utility model patent No. ZL202020094582.5 discloses a computerized jacquard machine that is easy to clean. It uses a motor to drive a second gear, which in turn drives a meshing first gear, which in turn drives a screw. The screw's rotation causes a threaded sleeve to move left and right, which in turn causes a slider to slide on a sliding rod, thus cleaning the jacquard operating chamber with a brush and reducing the machine's error rate. Additionally, by turning on a vacuum fan, airborne dust and lint are sucked into a dust collection box, effectively removing these impurities and reducing their harm to workers, ensuring the machine's normal operation. However, the technology disclosed in this patent primarily targets the cleaning of airborne cotton fibers inside the jacquard operating chamber, but the suction distance is relatively long, making the effect less significant. Summary of the Invention

[0004] This invention provides a jacquard machine head with a low failure rate that features a simple structure, good dust collection effect, long service life of the lifting device, resistance to wall panel deformation, and space saving.

[0005] A low-failure-rate jacquard machine head includes a wind chamber, a knife-lifting device, and side plates inside a component box. A low-position fan is installed inside the wind chamber, adhering to the top of the side plate. Double-wall plate devices are installed on both sides of the low-position fan device. A long-lasting lubrication device is installed on the knife-lifting device. This jacquard machine head uses the low-position fan device to directly adhere to the side plates inside the component box, adsorbing dust at close range and reducing dust accumulation issues. The double-wall plate device improves the overall operational stability of the knife-lifting device, and the long-lasting lubrication device on the knife-lifting device avoids the need for frequent machine shutdowns for lubrication.

[0006] The low-position fan device includes two dampers connected to the crossbeam, each with an air outlet. Two horizontal dampers, connected by a linkage device, are located inside the two dampers, and fans are mounted on these horizontal dampers. The horizontal dampers are flush against the top of the side panel. The linkage device includes a transverse linkage, with a lifting device connected to each end. Each lifting device includes a first linkage, one end of which is connected to the transverse linkage, and the other end of which is connected to a second and a third linkage. The second linkage connects to the horizontal damper via a pressure rod, and the third linkage connects to the damper. This linkage device lowers the overall position of the fan, bringing it closer to the side panel inside the component housing and improving dust collection efficiency.

[0007] The double-wall panel device includes a left-wall panel assembly formed by connecting two left-wall panels, and a right-wall panel assembly formed by connecting two right-wall panels. An upper swing shaft and a lower swing shaft connect the left and right-wall panel assemblies, and both the upper and lower swing shafts are connected to a knife-lifting device. A drive device for the upper and lower swing shafts is provided between the two right-wall panels. The drive device includes a drive shaft connected to a drive motor, and the drive shaft is equipped with a first eccentric wheel and a second eccentric wheel. The first eccentric wheel is connected to a first connecting rod plate, which is connected to the lower swing shaft via a first connecting shaft. The second eccentric wheel is connected to a second connecting rod plate, which is connected to the upper swing shaft via a second connecting shaft. The second connecting rod plate has a perforated hole through which the connecting shaft passes. The double-wall panel device improves the overall swing strength of the knife-lifting device by embedding the drive device between the two right-wall panels, increasing the overall compactness of the equipment and minimizing the space occupied by the jacquard machine head.

[0008] The lifting device includes an upper pull rod and a lower pull rod connected by a first screw. The lower pull rod connects to a frame plate, and a long-term lubrication device is connected to the shaft hole of the frame plate. The long-term lubrication device includes two pull rod plates. One end of each pull rod plate is connected to the shaft hole via a first bearing device, and the other end is connected to the cutter lifting lug via a second bearing device. The first bearing device includes a first bushing, with first end face bearings fitted on the outer circumference of both ends of the first bushing. The outer side of each first end face bearing is connected to a first pull rod shaft, and the two first pull rod shafts are connected by a second screw. The second bearing device includes a second bushing, with second end face bearings fitted on the outer circumference of both ends of the second bushing. The outer side of each second end face bearing is connected to a second pull rod shaft, and the two second pull rod shafts are connected by a third screw. A bushing connects the two first end face bearings. The bushing has an oil hole that connects to an oil chamber located on the cutter lifting lug, and the long-term lubrication performance is achieved by storing oil in the oil chamber.

[0009] This invention effectively extracts dust from inside the jacquard machine head through a low-position fan device, and the double-wall plate device greatly improves the stability of the knife-lifting device. The efficient lubrication structure installed on the knife-lifting device reduces the maintenance cost and failure rate of the entire jacquard machine head. Attached Figure Description
