Description

Technical Field

[0001] The present invention relates to the field of warp knitting machines, and more particularly to a wireless Jacquard jacquard device for high-speed warp knitting machines. Background Art

[0002] The traditional piezoelectric Jacquard drive system includes a Jacquard and a Jacquard drive device. Its structure is mainly that N Jacquards are installed on the comb. Among them, the Jacquard is installed on the comb, and the drive device of the Jacquard is usually installed on the warp knitting machine frame. Therefore, it is separated from the Jacquard, and the two are electrically connected through the Jacquard lead socket and the slot of the drive device of the Jacquard. Since each Jacquard includes multiple Jacquard needles (driven by piezoelectric ceramic sheets), and each Jacquard needle requires an independent drive cable for power supply, this results in thousands of drive cables being connected between the drive device and the Jacquard comb. This complex cable layout causes many inconveniences and limitations in practical applications.

[0003] The Chinese utility model patent previously applied for by the applicant (application number: 201922124965.2, publication number: CN211947458U) discloses a power supply connection structure for a warp knitting machine Jacquard comb, including a guiding and supporting component and a mounting rack installed on the guiding and supporting component. At least one layer of elongated mounting grooves is provided on the fixed rack, and insulating seats adapted to their sizes are arranged in the mounting grooves. The insulating seats are provided with at least two conductive strips that are electrically isolated from each other. One side of the conductive strip is buried in the insulating seat, and the other side of the conductive strip is exposed. Each conductive strip is correspondingly provided with a set of contact pieces arranged according to the number of Jacquard combs. One end of each contact piece abuts against the exposed side of the corresponding conductive strip, and the other end of the contact piece is used to connect to the circuit interface of a Jacquard comb. The applicant found in the actual use process that the prior application could meet the use requirements when the warp knitting machine rotates at 500 - 800 revolutions per minute. However, when the rotation speed of the warp knitting machine speeds up to, for example, 2000 - 3000 revolutions per minute, the data transmission speed of the power supply device with integrated electrical communication recorded in the prior application cannot meet the working condition requirements of 2000 - 3000 revolutions per minute, and the situation of insufficiently fast data transmission occurs. However, since the opening size of the mounting groove of the fixed rack (the fixed rack refers to the comb bed) is fixed and the space is narrow, it is impossible to set more than two conductive strips. In view of this situation, the applicant proposes this solution. Summary of the Invention

[0004] The present invention provides a wireless Jacquard jacquard device for a high-speed warp knitting machine, and its main purpose is to overcome the defect that the opening size of the mounting groove on the comb bed of the existing wireless Jacquard jacquard device is fixed and the space is narrow, and it is impossible to set more than two conductive strips.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A wireless Jacquard jacquard device for a high-speed warp knitting machine, comprising at least one Jacquard comb body and at least one power supply circuit board electrically connected to the Jacquard comb body. The power supply circuit board includes at least one first printed circuit board substrate, at least one positive conductive unit provided on the first printed circuit board substrate, at least one negative conductive unit provided on the first printed circuit board substrate, and two signal lines provided on the first printed circuit board substrate. The signal lines are used to transmit the control signals of the external RS485 communication bus. By arranging the positive conductive unit, the negative conductive unit and the two signal lines on the first printed circuit board substrate, the effect of arranging four wires in a narrow space is achieved, while meeting the requirement that the RS485 communication bus needs to use two signal lines to transmit control signals, increasing the data volume transmitted by the power supply circuit board, and on the other hand reducing the signal interference of the control signals of the RS485 communication bus.

[0007] Further, the positive conductive unit, the two signal lines, and the negative conductive unit are relatively spaced apart from each other, and the two signal lines are both arranged between the positive conductive unit and the negative conductive unit.

[0008] Further, adjacent first printed circuit board substrates are welded to each other by a plurality of welding rods. The adjacent two positive conductive units are connected by using welding rods, the adjacent two negative conductive units are connected by using welding rods, and the adjacent two signal lines are connected by using welding rods.

[0009] Further, the welding rods are arranged on the back surface of the first printed circuit board substrate.

[0010] Further, the Jacquard comb body includes at least one comb base provided on the comb bed and a thimble unit provided at the bottom of the comb base. The thimble unit includes at least one second printed circuit board substrate, at least one first conductive needle provided on the second printed circuit board substrate, at least one second conductive needle provided on the second printed circuit board substrate, and two third conductive needles provided on the second printed circuit board substrate. One end of the first conductive needle is electrically connected to the positive conductive unit, and the other end of the first conductive needle is electrically connected to the positive power supply terminal of the Jacquard control circuit. One end of the second conductive needle is electrically connected to the negative conductive unit, and the other end of the second conductive needle is electrically connected to the negative power supply terminal of the Jacquard control circuit. One end of the third conductive needle is electrically connected to the signal line, and the other end of the third conductive needle is electrically connected to the signal input terminal of the Jacquard control circuit.

[0011] Further, it further includes at least one clamping member for clamping the comb base and the comb bed together. By providing the clamping member to clamp the comb base and the comb bed together, it facilitates the installation and disassembly between the comb base and the comb bed. The comb base and the comb bed are detachably mounted on the clamping member, which is used to shorten the overall length of the Jacquard comb.

[0012] Further, one side of the clamping member is wrapped around the comb base, and the other side of the clamping member is wrapped around the comb bed, so that the clamping member, the comb base and the comb bed are integrated.

[0013] Further, it further includes at least one first assembly part provided on the rear part of the comb base and at least one second assembly part provided on the rear part of the comb bed and adapted to the first assembly part. The lower side of the first assembly part and the upper side of the second assembly part are detachably abutted against each other. One end of the clamping member is wrapped around the upper side of the first assembly part, and the other end of the clamping member is wrapped around the lower side of the second assembly part, so that the first assembly part and the second assembly part are integrated.

[0014] Further, the clamping member includes a clamping block for fixing the comb base, at least one first locking member provided at the rear end of the clamping block, and a clamping groove provided at the front end of the clamping block. The first assembly part and the second assembly part are both detachably embedded in the clamping groove. The first locking member is locked on the first assembly part by passing through the clamping groove from the rear part of the clamping block, so that the first assembly part is locked in the clamping groove.

[0015] Further, the lower side of the first assembly part and the upper side of the second assembly part are both stepped. The second assembly part is stacked on the first assembly part, so that the first assembly part pushes the second assembly part to move towards the clamping member during the locking process.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The structure of the present invention is simple and highly practical. By providing a first printed circuit board substrate, a positive conductive unit, a negative conductive unit, and two signal lines, on the one hand, by arranging the positive conductive unit, the negative conductive unit, and the two signal lines on the first printed circuit board substrate, the effect of arranging four wires in a narrow space is achieved. At the same time, it meets the requirement that the RS485 communication bus needs to use two signal lines to transmit control signals, increases the amount of data transmitted by the power supply circuit board, and meets the requirement of a large amount of data transmission when the warp knitting machine rotates at a high speed. On the other hand, the first printed circuit board substrate has high hardness and a long service life. Only arranging the positive conductive unit, the negative conductive unit, and the two signal lines on the first printed circuit board substrate improves the stability of the control signal transmission of the RS485 communication bus in the signal lines, reduces the signal interference of other circuits on the control signal of the RS485 communication bus, and achieves two benefits at once.

[0018] 2. In the present invention, by arranging the two signal lines between the positive conductive unit and the negative conductive unit, the positive conductive unit and the negative conductive unit play an isolating role, and the isolation effect is better, making the control signal of the RS485 communication bus transmitted by the signal lines more stable.

[0019] 3. In the present invention, by arranging a plurality of welding rods to weld two adjacent first printed circuit board substrates together, on the one hand, the length of the first printed circuit board substrate is extended, so that longer positive conductive units, negative conductive units, and signal lines can be arranged to supply power and transmit signals to more wireless jacquard combs. On the other hand, using welding rods to weld together improves the firmness of the connection and meets the requirements of power conduction and signal transmission at the same time, achieving two benefits at once.

[0020] 4. In the present invention, by arranging the welding rods on the back of the first printed circuit board substrate, on the one hand, the flatness of the front surface of the first printed circuit board substrate is improved, and the extension and conduction of the first printed circuit board substrate are realized. On the other hand, it has no influence on the power supply and signal reception of the first conductive pin, the second conductive pin, and the third conductive pin on the power supply circuit board, achieving two benefits at once.

[0021] 5. In the present invention, by arranging the first conductive pin, the second conductive pin, and the third conductive pin to be electrically connected to the positive conductive unit, the negative conductive unit, and the signal line respectively, the power supply circuit board supplies power to the jacquard control circuit and transmits the control signal of the RS485 communication bus, so that there is no cable between the jacquard comb and the comb bed, thereby reducing the length of the cable rope on the wireless jacquard device.

On the other hand, the first printed circuit board substrate 61 has high hardness and a long service life. Only arranging the positive conductive unit 62, the negative conductive unit 65, and two signal lines 63 on the first printed circuit board substrate 61 improves the stability of the control signal transmission of the RS485 communication bus in the signal lines 63, reduces the signal interference of other circuits on the control signal of the RS485 communication bus, achieving a two - pronged effect.

[0039] Example 2, refer to Figure 1 and Figure 5 The difference between the second embodiment and the first embodiment is that the wireless jacquard jacquard device includes at least one driving circuit board 4 for driving the piezoelectric ceramic element 3 of the jacquard comb body 51 to drive the jacquard needle assembly 5 to swing, and at least one control circuit board 67 for driving the driving circuit board 4.

[0040] Reference Figure 5 The driving circuit board 4 and the control circuit board 67 are arranged on the comb base 1 with relative intervals. By arranging the driving circuit board 4 and the control circuit board 67 with relative intervals, on the one hand, the driving circuit board 4 and the control circuit board 67 are separated, so that the heat generated during the operation of the circuit of the driving circuit board 4 and the heat generated during the operation of the circuit of the control circuit board 67 do not affect each other, thereby extending the service life. On the other hand, the driving circuit board 4 and the control circuit board 67 are separated, and the first power line 412 and the second power line 77 are independently arranged for independent power supply, thereby improving the stability of the driving circuit board 4 and the control circuit board 67, and extending the service life of the driving circuit board 4 and the control circuit board 67, thereby achieving the effect of killing two birds with one stone.

And when the address dialing unit is damaged, it can be directly replaced by plugging and unplugging, while the driving circuit board 4 can be reused, reducing the later maintenance cost of the driving circuit board 4.

[0046] Referring to Figure 4 , the address dialing unit includes at least one debugger 85 for setting the communication address, at least one dialing button panel 84 electrically connected to the debugger 85, at least one display 83 electrically connected to the debugger 85, and at least one signal output port electrically connected to the debugger 85.

The output terminal discharges the capacitor at one end of the Jacquard through the diode D1 and the transistor Q2. It should be particularly noted that at the moment when the discharge starts, after the diode D1 conducts, the transistor Q1 is in a reverse bias state, making the transistor Q1 turn off quickly and completely in the cut-off state, with almost no power consumption.

[0123] 2: When a high level is input to INPUT1 and a low level is input to INPUT2, Q4 is cut off, and Q4 is equivalent to an open circuit.
