Description

Double double-action electronic flower pillow

Technical field

The invention relates to an electronic jacquard machine, in particular to a double double-acting electronic flower pillow.

Background technique

The double-jawed mechanical jacquard weaving machine belongs to a kind of weaving machine, which is specialized in weaving traditional clothes. In recent years, electronic flower pillows have been widely used in the market instead of the traditional paper perforated tread plates, which retain the traditional craft style in weaving. The weaving efficiency is greatly improved and the production cost is reduced.

Since the number of horizontal needles engaged in the weaving work is so large that it cannot be directly completed using the electronic function, the action of the horizontal needle needs to be converted into a push pin, and the push pin breaks down the action of the horizontal needle into a single row or a double row. Each group after decomposition is called an electronic flower pillow. The push pin of the electronic flower pillow adopts a stepped arrangement, and the electronic controller is installed by pushing the side of the needle to be misplaced; the electronic flower pillow is mechanically driven to a certain frequency. Swinging, the push pin is a free body that can only slide back and forth in the electronic flower pillow. One end of the push pin corresponds to the horizontal pin, and the other end of the push pin uses a two-way electromagnetic valve to drive the slider to restrict or not limit the push pin. Stroke, whether to strike the horizontal needle, so that the horizontal needle reaches the knitting state required for "porous" or "no hole".

Chinese patent CN1580341A discloses a device for controlling the needle selection of a jacquard machine, and its working principle is to use the bistable needle selection solenoid valve 3 to achieve the two states of "porous" and "non-porous" of the electronic pattern, bistable The needle selection solenoid valve is provided with a movable coil 8a and a coil bobbin 8, and a coil 8b has a stopper 8b. The excitation system formed by the core 9 and the permanent magnet 10 provided on the core is fixed to the vertical groove of the electromagnetic valve seat. 3b. A positive current is applied to the coil, the movable coil and the bobbin move upward, and the stopper 8b does not block the push pin 6, forming a "porous" state of the electronic pattern, and the corresponding warp is lifted; a negative current is applied to the coil. The movable coil and the bobbin move downward, and the stopper 8b blocks the push pin 6, forming a "non-porous" state of the electronic pattern, and the corresponding warp is sunk. The device has certain advantages, but there are also some problems, such as: The push pin is a cylinder with a very large aspect ratio, which transmits the impact force in high-speed motion, and adopts such a solid structure, and the rigidity is relatively poor; When the horizontal pin is matched, since the surface of the push pin and the push pin frame are in the same arc shape, it is a linear contact, and the head of the push pin must be designed to extend the cantilever state of the push pin holder, and the horizontal needle must be The top is at the center of the push pin, otherwise the pin head is worn and deformed due to the eccentric load, and the pin is easily inserted, and the life of the push pin is not long.

Similarly Chinese patents CN20169570U, CN101509165A, CN1315665A, CN100436676C, etc. The push pins of the solid structure are used throughout, and the above defects such as poor rigidity are present.

Summary of the invention

The object of the invention is mainly to solve the problem that the conventional push pin has poor rigidity, short life and easy deformation of the card needle, and provides a double double-acting electronic flower pillow drive plate with a hollow push pin, and the jacquard loom capable of running at a high speed .

Another object of the present invention is to solve the problem of the linear contact between the conventional push pin head and the push pin holder, and provide a double-acting electronic flower pillow drive plate of the square push pin head, so that the push pin and the horizontal pin are matched on the push pin stand. Completed inside, improving the reliability of push and cross pin power transmission.

The technical solution adopted by the present invention to solve the above technical problem is: providing a double double-acting electronic flower pillow, comprising a push pin frame, a guiding frame, a push pin, a driving plate, a double compound needle selecting solenoid valve and an FPC flexible substrate, The driving plate is arranged with a plurality of sets of double double-acting needle selecting solenoid valves, wherein the double-double needle selecting solenoid valve has a fixing frame, and two grooves on the fixing frame are respectively mounted with magnetic steel, and the magnetic steel is iron The core, the middle of the core is a coil core of the movable connection, the middle of the coil core is wound with a coil, the end of the coil core is provided with a stopper, and the other end is provided with a terminal, and the terminal is connected to the driving circuit board through the FPC flexible substrate The iron core further has a layer of magnetic steel, iron core, coil core, coil and FPC flexible substrate; the coil core of the fixing frame is provided with one end of the stopper, and two positions respectively matching the stopper a through hole, one end of each of the two push pin bars is movably connected in the through hole, and the push pin is connected to the guide frame at the middle of the push pin, and the push pin head is a movable connection of the column body and the corresponding counterbore of the push pin frame, wherein: iron Polarity magnets disposed on opposite ends of the push rod is a hollow needle structure.

When the double-double-acting electronic flower pillow is working, the driving plate is mechanically driven to reciprocate according to a certain frequency, and each push pin is tilted back and forth in the electronic flower pillow by inertia and thrust according to the same frequency, in each movement, Each coil can receive the electrical signal provided by the drive circuit board, which causes the coil core to move toward which pole magnet, which drives the movement of the slider, whether to block the stroke of the push pin, and the push pin has impact and no impact. The ability of the horizontal needle to complete the work. Since the push pin works in the electronic flower pillow by the inertia and the thrust of the stroke end point, the work is characterized by the impact of the horizontal needle. This kind of long-diameter ratio is very easy to wear and deform when subjected to high frequency impact, so it is improved. The benefits of pushing the needle bar and reducing the weight of the needle bar are obvious: Reduce bending, reduce wear and extend the life of the push pin. As we all know, the hollow-structure is much stiffer than the solid structure, and the weight is much lighter. Of course, a solid structure can be used if necessary.

Preferably, the pusher head has a square structure. Compared with the traditional circular structure, the head of the square structure is in surface contact with the contact point of the counterbore of the push pin holder, and the traditional arc surface is the line contact, which increases the contact area and reduces the pressure, thereby reducing the pressure. abrasion. At the same time, the push pin head of the square structure has a larger weight than the conventional circular structure, and the response speed of the push pin is improved. On the one hand, the push pin of the hollow structure reduces the weight, and on the other hand, the weight of the pusher head is appropriately increased. improved The structure of the push pin is more ideal for the force.

Preferably, the connection between the pusher head and the pusher bar is an eccentric structure. It is mainly used for push pins with a large stitch length of 4 mm or more. Due to the structure of the electronic flower pillow, the eccentric structure is not used, and the stitch length of the push pin cannot be achieved.

Preferably, the stroke of the outer end surface of the pusher head is all within the counterbore of the pusher frame. Such a structure is to complete the cooperation of the push pin and the cross pin in the counterbore of the push pin frame to ensure the reliability of the force transmission.

Preferably, the square push pin has an arc chamfer at the corner.

Preferably, the magnetic steel has a rectangular structure, and the groove on the fixing frame for mounting the magnetic steel matches the shape of the magnetic steel. The purpose of this is to facilitate installation while preventing the magnet from being relatively turbulent.

Preferably, the terminal of the coil core has two parallel columns. The conventional terminal is a columnar body for fixed connection of the FPC flexible substrate. Since the coil core is a moving component, twisting or even falling off often occurs, affecting the transmission of electrical signals, causing defective products and malfunctions.

The double double-acting electronic flower pillow of the invention has obvious beneficial effects: using the push pin needle rod of the hollow structure and the square push pin head, appropriately reducing the weight of the needle body, appropriately increasing the weight of the head, and improving the push The rigidity of the needle optimizes the structure of the push pin, improves the stress condition of the push pin, prolongs the service life of the push pin, and reduces the occurrence point of the electronic flower pillow.
