Description

Technical Field

[0001] The invention relates to the field of jacquard pattern, in particular to a three-station jacquard pattern device for a warp knitting machine. Background Art

[0002] Jacquard devices are generally divided into mechanical jacquard devices, electromagnetic jacquard devices and piezoelectric jacquard devices. Among them, the piezoelectric jacquard device completely changes the characteristics of the jacquard device that requires complicated components such as wire and shift needles, which greatly improves the speed of the jacquard warp knitting machine and has become the mainstream configuration of modern jacquard warp knitting machines. It consists of two piezoelectric ceramics sandwiched on the left and right sides of a glass fiber sheet (insulation). Piezoelectric ceramics have the property of deforming themselves when voltage is applied, and copper sheets are commonly used as electrodes to transmit voltage. By switching the circuit switches on both sides, voltage is alternately applied to both sides of the piezoelectric jacquard element, causing the piezoelectric ceramic to deform, and eventually causing the yarn guide needle to shift to the left or right. Because the piezoelectric ceramic effect is like a capacitor, the piezoelectric jacquard element can remain in its offset position, and the offset needle distance is controlled by the current pulse.

[0003] In the existing jacquard device, the yarn guide needle can only achieve two positions, namely the basic position (also called the non-jacquard position) and the left offset position (also called the jacquard position). When the piezoelectric ceramic applies a positive voltage signal, the jacquard yarn guide needle offsets one stitch length to the left from the basic position. When the piezoelectric ceramic applies a negative voltage signal, the jacquard yarn guide needle offsets half a stitch length to the right and is located in the middle of the two knitting needles. This position is also called the basic position. There are only three types of yarn padding movements that can be formed ("thick, thin, and mesh"), which are relatively simple. With the increasing requirements of people on textile patterns, it is difficult to meet the requirements of only three tissue effects. For this reason, a three-position jacquard jacquard device for a warp knitting machine is proposed. Summary of the invention

DETAILED DESCRIPTION

[0022] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0023] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0024] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific examples below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0025] Example 1, please refer to Figure 1 to Figure 4 The structure shown in the embodiment of the present invention is a three-station jacquard device for a warp knitting machine, comprising a base 1, a cable assembly 2, a bimorph 4, and a yarn guide needle 5 installed at the end of the bimorph 4, and a paddle assembly 3 is also provided on the base 1;

[0026] The paddle assembly 3 includes a driving member and a paddle member 33 detachably connected to an output end of the driving member, and the driving member is used to drive the paddle member 33 to move along the width direction of the substrate 1;

[0027] The shifting member 33 includes a mounting seat 331, a receiving tube 337 arranged on one side of the mounting seat 331, a motor 332 and an air pump 333 arranged in the mounting seat 331, the output end of the motor 332 is detachably connected with a linkage member, the response end of the linkage member is provided with a blocking rod 3310 opposite to the yarn guide needle 5, and the blocking rod 3310 is provided with a cleaning bag 3312. The driving member drives the shifting member 33 to move to drive the blocking rod 3310 to move to the desired position, and the blocking rod 3310 is used to block the yarn guide needle 5.

[0028] In this embodiment, the base 1 is the basic part of the device, which provides a stable support and installation interface. A mounting groove is opened on the base 1 for fixing the dual piezoelectric chip 4. The base 1, the dual piezoelectric chip 4 and the yarn guide needle 5 all belong to the prior art, and their structures and functions are no longer repeated. In addition, in the prior art, the two working positions of the yarn guide needle 5 are the jacquard position and the non-jacquard position. When the dual piezoelectric chip 4 of the jacquard device does not apply a voltage signal, the yarn guide needle 5 is directly opposite to the knitting needle front and back. As a negative pressure or positive piezoelectric signal is applied to the dual piezoelectric chip 4, the yarn guide needle 5 is deflected accordingly.

[0029] Furthermore, the driving member includes a transverse movement mechanism 31 and a motor 32 . The motor 32 is used to drive the transverse movement mechanism 31 to move. The transverse movement mechanism 31 is detachably mounted on the bottom of the base 1 , and the mounting seat 331 is detachably mounted on the transverse movement mechanism 31 .

[0030] In this embodiment, the transverse movement mechanism 31 adopts a ball screw structure, including a frame, a screw and a nut seat, which is a prior art and will not be repeated here. The output end of the motor 32 is connected to the screw key to drive the screw to rotate, thereby driving the nut seat to move along the length direction of the screw. The mounting seat 331 is screwed to the nut seat and moves with the movement of the nut seat.

[0031] Furthermore, a receiving tube 337 is connected to the side of the mounting seat 331, and the linkage member is arranged in the receiving tube 337, and the inner cavity of the receiving tube 337 is connected to the inner cavity of the mounting seat 331;

[0032] The linkage includes a chain 334, a steering sprocket set 336, a gear 338 and a rotating ball 339. The motor 332 is used to drive the sprocket of the steering sprocket set 336 to rotate. The steering sprocket set 336 is used to drive the gear 338 to rotate. The gear 338 is used to drive the rotating ball 339 to rotate. The rotating ball 339 is provided with gear teeth that mesh with the gear 338.

[0033] In this embodiment, the receiving tube 337 adopts a bent tube so that one end of the receiving tube 337 can be extended to a position close to the yarn guide needle. There are two chains 334. The steering sprocket group 336 includes two sprockets. The rotating shaft of the gear 338 is also provided with a corresponding sprocket. One of the sprockets is connected to the output of the motor 332 through the chain 334, and the other sprocket is connected to the chain provided on the rotating shaft of the gear 338 through another chain 334. During the entire transmission process, the torque output by the motor 332 will eventually drive the rotating ball 339 to rotate.

[0034] Furthermore, the air outlet end of the air pump 333 is connected to the air pipe 335 , and the air outlet end of the air pipe 335 is in communication with the cleaning bag 3312 .

[0035] In this embodiment, in order to facilitate the storage of the air tube 335, most of the air tube 335 is laid inside the receiving tube 337 and fixed in the receiving tube 337 by buckles.

[0036] Furthermore, a rotating tube 3311 is arranged above the rotating ball 339 , the blocking rod 3310 is fixedly connected to the side wall of the rotating tube 3311 , and the end of the blocking rod 3310 is directly opposite to the yarn guide needle 5 , and the cleaning bag 3312 is laid on the blocking rod 3310 along the outer circumference of the blocking rod 3310 .

[0037] In this embodiment, an inner cavity is opened inside the blocking rod 3310, and the inner cavity is connected with the rotating tube 3311. Another part of the air pipe 335 passes through the placement tube 337 and is laid in the rotating tube 3311, and extends into the interior of the blocking rod 3310, thereby communicating with the cleaning bag 3312. The cleaning bag 3312 adopts an air bag. In addition, because the rotating tube 3311 needs to rotate with the rotating ball 339, the air pipe 335 passing through the placement tube 337 cannot be in a tight state, otherwise it will affect the rotation of the rotating tube 3311.

[0038] Furthermore, the number of the blocking members 33 is the same as that of the yarn guide needles 5 , the blocking rod 3310 is arranged on one side of the yarn guide needle 5 , the yarn guide needle 5 is provided with a needle groove 6 , and the needle groove 6 corresponds to a point of the rotation track of the blocking rod 3310 .

[0039] In this embodiment, when the blocking rod 3310 rotates to a certain position, the blocking rod 3310 corresponds to the needle groove 6. When the cleaning capsule 3312 is in an uninflated state, the size of the needle groove 6 is larger than the size of the cleaning capsule 3312. The cleaning capsule 3312 is annular and the needle groove 6 is circular. At this time, the shifting member 33 is driven to move, so that the cleaning capsule 3312 can be inserted into the needle groove 6, and the cleaning capsule 3312 can be inflated to make it larger until it contacts the groove wall of the needle groove 6. Note that it cannot be in close contact, only slight contact is allowed. Then, the gas in the cleaning capsule 3312 is extracted to make it smaller, and then it is removed from the needle groove 6. This operation process can clean the needle groove 6, and can clean the lubricating oil and debris on the needle groove 6.

[0040] Furthermore, a controller is provided in each of the driving member and the shifting member 33, and the controller is used to control the driving member, the shifting member 33 to be connected to an external master control network.

[0041] In this embodiment, the external master control can be the warp knitting machine master control, and instructions are input to the controller through the external master control to control the operation of the driving member and the shifting member 33. The signal connection between the external master control, the controller, and the driving member and the shifting member 33 belongs to the existing technology and will not be repeated here.

[0042] In the prior art, by inputting no voltage, negative voltage and positive voltage to the dual piezoelectric chip 4, the guide needle 5 can be gradually kept stationary, shifted half a needle position to the right (at this time, the needle groove 6 of the guide needle 5 is located in the middle of the two knitting needles), and shifted one needle position to the left (at this time, the needle groove of the guide needle 5 is shifted half a needle position to the left compared to the initial position, and is located in the middle of the two knitting needles on the left side of the initial position). The three-station jacquard device of the warp knitting machine can provide another station. When a positive pressure is input to the dual piezoelectric chip 4, the guide needle 5 is shifted one needle position to the left. The other station provided by the three-station jacquard device of the warp knitting machine is located in this process, that is, the guide needle 5 is shifted to the left. , it is blocked before it moves one needle position, and its displacement distance is greater than the zero needle position and less than one needle position. The specific operating steps are as follows: when the guide needle 5 moves half a needle position to the right from the initial position, the controller starts the motor 32, thereby controlling the shifting member 33 to move until the end of the blocking rod 3310 contacts the guide needle 5, and then controls the blocking rod 3310 to move in the opposite direction for a certain distance (this distance is less than one needle position and is not equal to half a needle position) according to the advance distance set in advance, and then a positive voltage is applied to the piezoelectric dual chip 4, and the guide needle 5 deflects in the opposite direction until it is blocked by the blocking rod 3310, and the guide needle 5 stops at this position, and finally the increase of the guide needle 5 position is completed.

[0043] It should be noted that when completing the above-mentioned increase in the yarn guide needle 5 station, during the process of the blocking rod 3310 blocking the yarn guide needle 5, the end of the blocking rod 3310 cannot be opposite to the needle groove 6, and the end of the blocking rod 3310 is located at the upper part of the needle groove 6.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
