Description

Technical Field

[0001] This utility model relates to the field of knitting machinery and equipment technology, and in particular to a jacquard needle selection device and a knitting system using the same. Background Technology

[0002] The circular knitting machine, a crucial machine in the textile industry, is responsible for producing various knitted fabrics commonly found in our daily lives. Whether it's T-shirts, sweatshirts, shirts, or household towels, curtains, bedding, and other items, the exquisite patterns such as jacquard, rib, and knit-like crochet designs on them all rely on the meticulous craftsmanship of the circular knitting machine.

[0003] A circular knitting machine, also known as a circular weft knitting machine, works by using a series of knitting machine accessories to weave various knitted fabrics. In this machine, the yarn moves smoothly along the weft direction, sequentially bending into loops and interlocking to ultimately form the familiar knitted fabric. Its knitting process is quite similar to hand-knitting sweaters, except that it achieves higher efficiency and quality through mechanical power and precise control.

[0004] A needle selector is an automated control component used in circular knitting machines. Through computer control, the needle selector can enable the fabrics woven by the circular knitting machine to have a wide variety of patterns and colors. For the installation location and operating principle of the needle selector on the circular knitting machine, please refer to existing patent documents such as CN103696114A, CN120738835A, and CN116607257B.

[0005] As shown in the prior art with announcement number CN 217266252 U, most circular knitting machines on the market currently use needle selectors driven by electromagnetic principles. The electromagnets correspond one-to-one with the cutter heads with permanent magnets, and the permanent magnets on the cutter heads face the end face of the electromagnet core. By changing the polarity of the electromagnets, the cutter heads can be driven to swing up and down around the fixed axis of the cutter heads.

[0006] Taking a circular jacquard knitting machine as an example, the cutter head swings up and down. When the cutter head swings upward, its tip contacts the protruding feet of the jacquard piece, pressing the jacquard piece into the needle cylinder as the machine runs. When the cutter head swings downward, it passes between the two protruding feet of the jacquard piece, avoiding contact and preventing it from pressing the piece in. The jacquard knitting control is achieved by switching between these two states.

[0007] Existing needle selectors all use a continuously energized electromagnet to oscillate the cutter head, thus achieving contact or non-contact between the cutter head tip and the working surface of the jacquard piece. This method has the following drawbacks: 1. Electromagnets are always energized, resulting in high workload, high power consumption, and short service life; 2. The cutter head makes hard contact with the jacquard piece in a rapid oscillating manner, and the jacquard piece is subjected to very high pressure. This places very high demands on the materials and hardness of the jacquard piece and the selector cutter head. In addition, the jacquard piece is easily worn and needs to be replaced frequently, which is costly. 3. The blade head needs to switch quickly between contacting or not contacting the protruding foot of the jacquard piece. As long as the blade head contacts the jacquard piece, the jacquard piece is selected and pressed into the syringe (without needle). To ensure that the protruding foot of the jacquard piece is precisely located between two adjacent blade heads, it will not be selected. This structure requires extremely high precision in controlling the blade head swing, and the probability of accidental contact is high, resulting in a high misselection rate. 4. The cutter head needs to be equipped with a permanent magnet, and an electromagnet needs to be set up to be used in conjunction with the cutter head with the permanent magnet. At least two types of magnets are needed to achieve the above functions, which is costly. Utility Model Content

[0008] The purpose of this invention is to provide a jacquard needle selection device and a knitting system using the same, which can at least solve one of the above-mentioned problems.

[0009] According to one aspect of the present invention, a jacquard needle selecting device is provided, comprising at least: The outer shell forms a space for containment; The blade head is movably mounted on the housing and engages with the protruding feet on the jacquard piece; An elastic element is movably disposed in the housing and cooperates with the cutter head; A magnetic suction mechanism is installed within the receiving space and cooperates with the cutter head; The control mechanism is located within the accommodating space and is electrically connected to the magnetic attraction mechanism; Under the control of the control mechanism, the magnetic attraction mechanism can attract or not attract the cutter head.

[0010] In some implementations, when the control mechanism controls the magnetic attraction mechanism to be inactive, the cutter head makes elastic contact with the protrusion on the jacquard piece under the action of the elastic element. When the control mechanism controls the magnetic attraction mechanism to be active, the cutter head is attracted by the magnetic attraction mechanism and swings to a position where it can no longer contact the protrusion on the jacquard piece.

[0011] In some embodiments, the magnetic attraction mechanism includes a coil, and the blade is made of a paramagnetic metal; When the control coil of the control mechanism is not energized, the cutter head makes elastic contact with the protruding foot on the jacquard piece under the action of the elastic element. When the control coil of the control mechanism is energized, the cutter head is attracted by the magnetic attraction mechanism and swings to a position where it can no longer contact the protruding foot of the jacquard piece.

[0012] Therefore, the working principle of the magnetic attraction mechanism is as follows: when the coil is energized, it generates a magnetic field that can attract the cutter head made of paramagnetic metals such as iron, cobalt, and nickel. When the power is turned off, the magnetic field disappears, and the cutter head is reset under the action of the elastic element.

[0013] In some embodiments, there are multiple cutter heads, which are arranged sequentially at intervals along the width direction of the housing. There are multiple jacquard pieces, which are divided into multiple jacquard piece groups. Each jacquard piece group includes multiple jacquard pieces with protrusions distributed from high to low. The multiple cutter heads correspond one-to-one with the multiple jacquard pieces with protrusions distributed from high to low in the jacquard piece group.

[0014] In some implementations, there are multiple coils, with each coil controlling 1-4 cutting heads.

[0015] In some embodiments, the jacquard needle selector device further includes a first connecting shaft, and the cutter head has a first connecting hole that mates with the first connecting shaft. All cutters are rotatably mounted on the housing via the first connecting shaft.

[0016] In some embodiments, the end face where the cutter head mates with the elastic element is the first end face, the end face where the cutter head mates with the protruding foot is the second end face, and the end face where the cutter head mates with the magnetic attraction mechanism is the third end face. The distance from the center of the first connecting hole to the second end face is greater than the distance from the center of the first connecting hole to the first end face, and the distance from the center of the first connecting hole to the third end face is greater than the distance from the center of the first connecting hole to the first end face. This creates two force-saving lever structures: one structure reduces the contact force between the protruding foot and the cutter head, protecting the cutter head; the other structure reduces the force required for the magnetic attraction mechanism to overcome the resistance of the cutter head and attract it, facilitating magnetic control and reducing the cost of the magnetic attraction mechanism.

[0017] In some embodiments, the jacquard needle selector further includes a second connecting shaft, and the elastic element includes a mounting end and a spring end. The mounting end is rotatably mounted on the housing via the second connecting shaft, and the spring end includes a plurality of spaced springs that correspond one-to-one with a plurality of cutter heads.

[0018] In some embodiments, the jacquard needle selector further includes a buffer guide rod, and the housing includes a limiting plate. The limiting plate is installed at the front end of the housing and engages with the buffer guide rod for limiting. The buffer guide rod is installed on the limiting plate and engages with the cutting head. Thus, the limiting plate enables the installation and limiting of the buffer guide rod, which in turn provides a buffering effect, reducing the impact force on the cutting head and extending its service life.

[0019] In some implementations, the limiting plate is a magnetically conductive element.

[0020] According to another aspect of the present invention, a knitting system is also provided, including a needle cylinder, knitting needles, an intermediate transmission component, a cam mechanism, and a needle selector. The cam mechanism is disposed on the outer periphery of the needle cylinder, and the knitting needles are installed in the needle grooves of the needle cylinder and are driven and cooperated with the cam mechanism through the intermediate transmission component. The intermediate transmission component includes a jacquard plate that cooperates with the needle selector and a needle-lifting plate that connects the jacquard plate and the knitting needle. The needle selector is the aforementioned jacquard needle selector device.

[0021] The beneficial effects of this utility model are: 1. This utility model provides a novel jacquard needle selection device, which changes the structure and principle of the traditional needle selector. It achieves elastic contact between the cutter head and the jacquard piece and automatic mechanical reset function through an elastic element, and achieves magnetic suction function of the cutter head through a magnetic suction mechanism. The cutter head contacts the protruding foot of the jacquard piece through elastic contact, resulting in low pressure on the jacquard piece. This reduces the requirements for the materials and hardness of the jacquard piece and the needle selector cutter head, and the jacquard piece is not easily worn, eliminating the need for frequent replacement of the jacquard piece and greatly extending its service life, thereby reducing costs. 2. Under normal circumstances, the jacquard pieces are always in elastic contact. The cutter head exerts contact pressure on the jacquard pieces, while the jacquard pieces exert a reverse force on the cutter head. In this state, the cutter head, in conjunction with the triangular mechanism, can automatically press the jacquard pieces into place. The specific principle is as follows: after the jacquard pieces reach the designated notch position, the reverse force of the jacquard pieces on the cutter head disappears, and the jacquard pieces are pressed into the designated notch under the contact pressure of the cutter head, thus achieving the effect of not releasing the needle. Conversely, when needle release is required, the magnetic attraction mechanism is activated by power to attract the cutter head. The jacquard pieces will not be pressed into place when passing through the designated notch position, and the jacquard pieces can pass smoothly, thereby driving the knitting needle to complete the needle release. This elastic contact structure means that the control mechanism only needs to issue control commands on whether the magnetic attraction mechanism attracts the cutter head, which reduces the accuracy requirements for cutter head control and results in an extremely low misselection rate. 3. The magnetic attraction mechanism only works when the needle needs to be dispensing, that is, when the coil is energized. The magnetic attraction mechanism does not work when the needle does not need to be dispensing, which greatly reduces the workload of the magnetic attraction mechanism, resulting in low power consumption and long service life. 4. The cutter head does not need to be equipped with a permanent magnet; it only needs to be made of paramagnetic material. Moreover, the magnetic attraction mechanism is used for the coil. Therefore, the manufacturing cost of the core components of this solution is high.

[0022] In summary, the jacquard needle selection device of this utility model has many advantages such as low cost, rapid response, low power consumption, and long service life. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Figure 1-8 The diagram schematically illustrates a jacquard needle selection device according to one embodiment of the present invention.

[0027] like Figure 1-8 As shown, this jacquard needle selection device is used in circular knitting machines. Together with components such as needle cylinders, needles, cams and cam seats (cam mechanisms or cam systems), sinkers (only found in single-sided knitting machines), etc., it forms the knitting system of the circular knitting machine. The knitting system is the "heart" of the circular knitting machine.

[0028] The jacquard needle selection device includes at least: The outer shell 1 forms an accommodating space 10; The blade 2 is movably mounted on the housing 1 and engages with the protruding foot 200a on the jacquard piece 200; The elastic element 3 is movably disposed in the housing 1 and cooperates with the cutter head 2; The magnetic attraction mechanism 4 is located within the accommodating space 10 and cooperates with the cutter head 2; When the magnetic attraction mechanism 4 is not working, the cutter head 2 is elastically contacted and engaged with the protruding foot 200a on the jacquard piece 200 under the action of the elastic element 3. When the magnetic attraction mechanism 4 is working, the cutter head 2 is attracted to the outer shell 1 by the magnetic attraction mechanism 4 and does not contact the protruding foot 200a of the jacquard piece 200.

[0029] Preferably, the magnetic attraction mechanism 4 includes a coil, and the cutter head 2 is made of a paramagnetic metal; When the coil is not energized, the cutter head 2 makes elastic contact with the protruding foot 200a on the jacquard piece 200 under the action of the elastic element 3. When the coil is energized, the cutter head 2 is attracted to the outer shell 1 and does not contact the protruding foot 200a of the jacquard piece 200.

[0030] Therefore, the working principle of the magnetic attraction mechanism 4 is as follows: when the coil is energized, it generates a magnetic field that can attract the cutter head 2 made of paramagnetic metals such as iron, cobalt, and nickel. When the power is cut off, the magnetic field disappears, and the cutter head 2 is reset under the action of the elastic element 3.

[0031] Preferably, there are multiple cutter heads 2, which are arranged sequentially at intervals along the width direction of the outer shell 1. There are multiple jacquard pieces 200, which are divided into multiple jacquard piece groups 300. Each jacquard piece group 300 includes multiple jacquard pieces 200 with protrusions 200a distributed from high to low. The multiple cutter heads 2 correspond one-to-one with the multiple jacquard pieces 200 with protrusions 200a distributed from high to low in the jacquard piece group 300.

[0032] As a further preferred option, such as Figure 5 As shown, in this embodiment, a jacquard piece group 300 includes 8 jacquard pieces 200, and there are 8 corresponding cutter heads 2.

[0033] Preferably, there are multiple coils, with each coil controlling 1-4 cutter heads 2.

[0034] As a further preferred embodiment, this embodiment uses two coils, each controlling four cutter heads 2. Since there are gaps between the jacquard pieces 200 of the jacquard piece group 300, there is a time difference between two adjacent jacquard pieces 200 during operation. During this time difference, the magnetic attraction mechanism 4 can completely switch between on and off states, and thus make specific actions to determine whether to attract the cutter head 2 corresponding to a certain jacquard piece 200.

[0035] As a preferred embodiment, the jacquard needle sorting device also includes: The control mechanism is located in the accommodating space 10 and cooperates with the magnetic attraction mechanism 4; The control mechanism is used at least to control whether the coil of the magnetic attraction mechanism 4 is energized.

[0036] The control mechanism in this embodiment can be a control circuit board disposed in the accommodating space 10, and the control circuit board integrates at least a microcontroller or other driver chip.

[0037] Preferably, the jacquard needle selection device also includes a first connecting shaft 5, and the cutter head 2 is provided with a first connecting hole 24 that cooperates with the first connecting shaft 5. All cutter heads 2 are rotatably mounted on the housing 1 through the first connecting shaft 5.

[0038] As a preferred option, such as Figure 4 and Figure 6 As shown, the end face of the cutter head 2 that mates with the elastic element 3 is the first end face 21, the end face of the cutter head 2 that mates with the protruding foot 200a is the second end face 22, and the end face of the cutter head 2 that mates with the magnetic attraction mechanism 4 is the third end face 23. The distance L2 from the center of the first connecting hole 24 to the second end face 22 is greater than the distance L1 from the center of the first connecting hole 24 to the first end face 21, and the distance L3 from the center of the first connecting hole 24 to the third end face 23 is greater than the distance L1 from the center of the first connecting hole 24 to the first end face 21. Thus, two force-saving lever structures can be formed: one force-saving lever structure makes the contact force between the protruding foot 200a and the cutter head 2 less (that is, the reaction force of the protruding foot 200a on the cutter head 2 is also less), which plays a role in protecting the cutter head 2; the other force-saving lever structure makes the force required for the magnetic attraction mechanism 4 to overcome the resistance of the cutter head 2 itself and attract the cutter head 2 less, which is convenient to achieve magnetic attraction control and has a lower requirement for the magnetic attraction force of the magnetic attraction mechanism 4. Therefore, the cost of the magnetic attraction mechanism 4 can be reduced.

[0039] Preferably, the jacquard needle selection device further includes a second connecting shaft 6, and the elastic element 3 includes a mounting end 31 and a spring piece 321 end 32. The mounting end 31 is rotatably mounted on the housing 1 via the second connecting shaft 6, and the spring piece 321 end 32 includes a plurality of spaced spring pieces 321 that correspond one-to-one with a plurality of cutter heads 2.

[0040] As a further preferred option, there are 8 shrapnel pieces 321.

[0041] Preferably, the jacquard needle selector also includes a buffer guide rod 7, and the housing 1 includes a limiting plate 11. The limiting plate 11 is installed at the front end of the housing 1 and engages with the cutter head 2 for limiting. The front end of the buffer guide rod 7 is embedded in the limiting plate 11 and engages with the cutter head 2. Thus, the limiting plate 11 facilitates the installation and limiting of the buffer guide rod 7, and the buffer guide rod 7 plays a buffering role, reducing the impact force of the cutter head 2 and extending its service life.

[0042] As a further preferred option, the limiting plate 11 can be a magnetically conductive component such as an iron sheet, and the buffer guide rod 7 can be a silicone pillar, etc.

[0043] The working principle of the jacquard needle selection device of this utility model is as follows: The jacquard needle selection device is the "brain" and instruction execution mechanism of a modern computerized circular knitting machine. Its core task is to precisely control whether each needle is "working" or "not working" according to the preset pattern file, thereby weaving different patterns on the fabric. Simply put, the whole process is: pattern design software → main controller → jacquard needle selection device driver chip → magnetic suction mechanism 4 → cutter head 2 action.

[0044] The specific steps are as follows: S1. Pattern Preparation: Design the jacquard pattern on the computer. The software will convert each point (pixel) of the pattern into a corresponding "0" and "1" signal sequence. "1" means that the needle needs to be selected (working) on ​​that path, and "0" means not selected. S2. Signal Synchronization and Distribution: The main controller (an industrial computer) synchronously and rapidly distributes the "0 / 1" signals at the corresponding positions to the drive chips on each jacquard needle selection device based on the real-time rotation angle of the circular knitting machine (obtained through an encoder). S3, Current Drive: After receiving the signal, the drive chip controls a high-current switching circuit to energize or de-energize the coil of the corresponding magnetic attraction mechanism 4. S4. Magnetic Action: When energized, the magnetic attraction mechanism 4 generates a magnetic field, attracting the cutter head 2 that needs to be controlled, preventing it from contacting the protruding foot 200a of the corresponding jacquard piece 200. The jacquard piece 200 passes smoothly, completing the needle exit. When de-energized, the magnetic attraction mechanism 4 loses its magnetism, and the cutter head 2 resets under the action of the elastic element 3, elastically contacting and cooperating with the protruding foot 200a of the jacquard piece 200. During the operation of the jacquard piece 200, if it reaches the designated notch position, the reverse force of the jacquard piece 200 on the cutter head 2 disappears, and the jacquard piece 200 is pressed into the designated notch under the contact pressure of the cutter head 2, thereby achieving the effect of not exiting the needle. S5. Mechanical needle selection: Whether the cutter head 2 is attracted by the magnetic attraction mechanism 4 determines the movement trajectory of the corresponding jacquard piece 200, and ultimately controls whether the knitting needle forms loops, gathers loops, or floats.

[0045] It should be noted that the jacquard needle selector does not directly control the knitting needles; it only controls the jacquard piece 200. The final movement of the knitting needles is accomplished through a track called the "triangle mechanism".

[0046] This utility model also discloses a knitting system, including a needle cylinder, knitting needles, an intermediate transmission component, a cam mechanism, and a needle selector. The cam mechanism is disposed on the outer periphery of the needle cylinder. The knitting needles are installed in the needle grooves of the needle cylinder and are driven and cooperated with the cam mechanism through the intermediate transmission component. The intermediate transmission component includes a jacquard plate that cooperates with the needle selector and a needle-lifting plate that connects the jacquard plate and the knitting needle. The needle selector is the aforementioned jacquard needle-selecting device. The knitting system is an important component of a circular knitting machine, and its structure is prior art, so it will not be described in detail here. For the specific structure of the knitting system and the specific placement of the needle selector, please refer to existing patent documents such as CN103696114A, CN120738835A, and CN116607257B.

[0047] The jacquard needle selection device of this invention has at least the following advantages over existing jacquard needle selection devices: 1. This utility model provides a novel jacquard needle selection device, which changes the structure and principle of the traditional needle selector. It achieves elastic contact between the cutter head 2 and the jacquard piece 200 and automatic mechanical reset through the elastic element 3, and achieves magnetic attraction of the cutter head 2 through the magnetic attraction mechanism 4. The cutter head 2 contacts the protruding foot 200a of the jacquard piece 200 through elastic contact. The pressure on the jacquard piece 200 is small, which reduces the requirements for the materials and material hardness of the jacquard piece 200 and the needle selector cutter head 2. Moreover, the jacquard piece 200 is not easily worn, and there is no need to frequently replace the jacquard piece 200, which greatly extends the service life of the jacquard piece 200 and thus reduces the cost. 2. Under normal circumstances, the jacquard piece 200 is always in elastic contact. The cutter head 2 exerts contact pressure on the jacquard piece 200, while the jacquard piece 200 exerts a reverse force on the cutter head 2. In this state, the cutter head 2, in conjunction with the triangular mechanism, can automatically press the jacquard piece 200 into place. Specifically, when the jacquard piece 200 reaches the designated notch position, the reverse force of the jacquard piece 200 on the cutter head 2 disappears, and the jacquard piece 200 is pressed into the designated notch under the contact pressure of the cutter head 2, thus achieving the effect of not releasing the needle. Conversely, when needle release is required, the magnetic attraction mechanism 4 is activated by power to attract the cutter head 2. The jacquard piece 200 will not be pressed into place when passing through the designated notch position, and the jacquard piece 200 can pass smoothly, thereby driving the knitting needle to complete the needle release. This elastic contact structure means that the control mechanism only needs to issue a control command on whether the magnetic attraction mechanism 4 attracts the cutter head 2, which reduces the accuracy requirement for the control of the cutter head 2 and results in an extremely low misselection rate. 3. The magnetic attraction mechanism 4 only works when the needle needs to be dispensed, that is, when the coil is energized. When the needle does not need to be dispensed, the magnetic attraction mechanism 4 does not work, which greatly reduces the workload of the magnetic attraction mechanism 4, resulting in low power consumption and long service life. 4. The cutter head 2 does not need to be equipped with a permanent magnet, and only needs to be made of paramagnetic material. Moreover, the magnetic attraction mechanism 4 is a coil. Therefore, the manufacturing cost of the core component of this solution is high.

[0048] In summary, the jacquard needle selection device of this utility model has many advantages such as low cost, rapid response, low power consumption, and long service life.

[0049] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
