[0023] The glove machine proposed in this utility model that avoids magnetic field interference has the following beneficial effects:

[0024] (1) After the first magnetic rod of the magnetic rod assembly of this glove machine is magnetized, the top end is N pole and the top end of the second magnetic rod is magnetized. The top end of the first magnetic rod and the top end of the second magnetic rod are connected by a spring needle, so that the magnetic field lines outside the first and second magnetic rods can propagate in the spring needle. This can reduce magnetic field interference with the surrounding magnetic rod assembly and reduce energy loss of magnetic field lines, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0025] (2) The first magnetic rod of this glove machine is in contact with the N pole of the permanent magnet, and the second magnetic rod is in contact with the S pole of the permanent magnet. The first magnetic rod, the permanent magnet and the second magnetic rod are regarded as a whole magnet. The first magnetic rod is the N pole of the magnet and the second magnetic rod is the S pole of the magnet. The N pole and S pole of the magnet are connected by a spring needle, so that the magnetic field lines outside the magnet can be propagated in the spring needle. This can reduce the magnetic field interference with the surrounding magnetic rods and reduce the energy loss of the magnetic field lines, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0026] (3) The magnetic rod assembly of this glove machine also includes an isolation plate, which isolates the ends of the first magnetic rod and the second magnetic rod away from the permanent magnet, preventing the ends of the first magnetic rod and the second magnetic rod away from the permanent magnet from directly contacting each other. This prevents magnetic field lines from propagating from the position where the first magnetic rod and the second magnetic rod are in direct contact to the second magnetic rod outside the overall magnet formed by the permanent magnet, the first magnetic rod and the second magnetic rod, thus reducing the magnetic field lines propagating from the spring needle and thereby enhancing the attraction force of the first magnetic rod and the second magnetic rod on the spring needle.

[0027] (4) The first magnetic rod of this glove machine has a first contact surface at the top and the second magnetic rod has a second contact surface at the top. The first contact surface and the second contact surface are on the same horizontal plane. When the first magnetic rod and the second magnetic rod attract the spring needle, the first contact surface and the second contact surface are in better contact with the spring needle, so that the spring needle can better conduct the first contact surface and the second contact surface, further reducing the dispersion of magnetic field lines, enhancing the attraction force of the first magnetic rod and the second magnetic rod on the spring needle, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0028] (5) The first magnetic rod of this glove machine includes a main body, an inclined part and an extension part. The inclined part is inclined at the top of the main body towards the direction of the second magnetic rod. The extension part is located at the top of the inclined part, so that the distance between the extension part and the second magnetic rod is smaller than the distance between the main body and the second magnetic rod, thereby reducing the distance between the first contact surface and the second contact surface, and ensuring that the first contact surface and the second contact surface can make contact with different positions of the spring needle.

[0029] (6) The magnetic rod base of this glove machine is provided with a third fixed cavity at both ends, which are connected to the first fixed cavity and the second fixed cavity respectively. The N pole and S pole of the permanent magnet are located at both ends of the permanent magnet. Therefore, the N pole of the permanent magnet is attached to the bottom end of the first magnetic rod at one end of the third fixed cavity, and the S pole of the permanent magnet is attached to the bottom end of the second magnetic rod at the other end of the third fixed cavity, so that the first magnetic rod, the permanent magnet and the second magnetic rod form a U-shaped integral magnet.

[0030] (7) The first magnetic rod of this glove machine is provided with a first limiting plate and the second magnetic rod is provided with a second limiting plate. The first limiting plate abuts against the top of the permanent magnet, which can increase the contact area between the first magnetic rod and the permanent magnet. At the S end of the permanent magnet, the second limiting plate abuts against the top of the permanent magnet, which can increase the contact area between the second magnetic rod and the permanent magnet, thereby enhancing the magnetization effect of the first and second magnetic rods, and further enhancing the attraction force of the first and second magnetic rods on the spring needle, ensuring the accuracy of needle selection.

[0031] (8) The tail end of the first coil of this glove machine is connected to the head end of the second coil, thereby connecting the first coil and the second coil in series; the head end of the first coil is connected to the positive terminal of the power supply circuit, and the tail end of the second coil is connected to the negative terminal of the power supply circuit, thereby forming a closed loop, so that the power supply circuit can simultaneously pass current through the first coil and the second coil, thereby making the needle selector structure more compact and reducing production costs.

[0032] (9) The tail end of the second coil of this glove machine extends to the side where the head end of the first coil is located, so that the tail end of the second coil and the head end of the first coil are on the same side. Therefore, the head end of the first coil is connected to the positive terminal of the power supply circuit and the tail end of the second coil is connected to the negative terminal of the power supply circuit on the same side. This makes the connection between the first coil and the second coil and the power supply circuit simpler and more convenient, easier to implement, and the wiring of the power supply circuit is more regular, which makes the implementation of the magnetic rod assembly simpler and more convenient, and further improves production efficiency.

[0033] (10) A wire routing groove is provided on one side of the magnetic rod base of this glove machine. When the tail end of the second coil extends to the side where the head end of the first coil is located, the head end of the first coil and the tail end of the second coil are both routed through the wire routing groove. The wire routing groove limits the head end of the first coil and the tail end of the second coil, thereby making the routing of the first coil and the second coil more regular, further making the implementation of the magnetic rod assembly simpler and more convenient, and improving production efficiency.

[0034] (11) The needle selector of this glove machine includes a needle selector seat, and multiple magnetic rod assemblies are arranged in at least two rows on the needle selector seat. The multiple magnetic rod assemblies arranged in adjacent rows are staggered in sequence, so that the multiple magnetic rod assemblies can attract or release their respective corresponding spring needles. During the process of multiple magnetic rod assemblies attracting or releasing their respective corresponding spring needles, the movement trajectories of all spring needles do not overlap, thereby preventing mutual interference between spring needles, thus ensuring the accuracy of needle selection and improving production efficiency.

[0035] (12) The needle selection seat of this glove machine is composed of a first seat body and a second seat body. A first half cavity is provided in the first seat body and a second half cavity is provided in the second seat body. A first row of magnetic rods is provided in the first half cavity and a second row of magnetic rods is provided in the second half cavity. The first row of magnetic rods provided in the first half cavity and the second row of magnetic rods provided in the second half cavity are misaligned, so that when the first row of magnetic rods and the second row of magnetic rods attract or release the corresponding spring needles, the spring needles will not interfere with each other.

[0036] (13) The multiple spring needles of this glove machine include multiple short needles and multiple long needles. The multiple short needles and multiple long needles are arranged alternately so that the multiple magnetic rod assemblies in the first row can attract or release multiple short needles respectively, and the multiple magnetic rod assemblies in the second row can attract or release multiple long needles respectively, thereby ensuring that the multiple magnetic rod assemblies set on the needle selection seat can attract or release the corresponding spring needles, thereby realizing the needle selection of the needle selector;

[0037] (14) The glove machine has multiple magnetic rod protrusions at the top of the first and second cavities with one end open, and multiple magnetic rod positioning grooves at the bottom of the first and second cavities with one end open, so that the top of the magnetic rod assembly can be slidably inserted into the magnetic rod protrusion through the opening of the magnetic rod protrusion, and the bottom of the magnetic rod assembly can be slidably inserted into the magnetic rod positioning groove through the opening of the magnetic rod positioning groove. This makes the installation of the first row of magnetic rod assemblies in the first base and the installation of the second row of magnetic rod assemblies in the second base simpler and more convenient, and thus makes the implementation of the glove machine simpler and more convenient.

[0038] (15) Each magnetic rod positioning slot of this glove machine is provided with a wiring hole at the bottom and a control board is provided at the bottom of the needle selector. The first coil end and the second coil end of the wires that pass through the wiring slots pass through the wiring holes and are fixedly connected to the control board. Thus, the first coil end and the second coil end of all magnetic rod components are integrated on the control board. Finally, the wires are led out through the control board and connected to the positive and negative terminals of the power supply circuit, which makes the wiring of the needle selector simpler and facilitates the implementation of this glove machine.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0054] Please see Figures 1-12 This utility model discloses a glove machine for avoiding magnetic field interference, including a needle selector 1 and a needle plate assembly 2 disposed above the needle selector 1. The needle selector 1 is provided with a plurality of magnetic rod assemblies 11, and the needle plate assembly 2 is provided with a plurality of spring needles 21 corresponding one-to-one with the plurality of magnetic rod assemblies 11. The magnetic rod assembly 11 includes a first magnetic rod 111 and a second magnetic rod 112 disposed at intervals, a first coil 113 disposed on the first magnetic rod 111, and a second coil 114 disposed on the second magnetic rod 112. After the first magnetic rod 111 is magnetized, its top end is N pole, and after the second magnetic rod 112 is magnetized, its top end is S pole. The current flow directions of the first coil 113 and the second coil 114 are opposite. The energized first coil 113 demagnetizes the first magnetic rod 111, and the energized second coil 114 demagnetizes the second magnetic rod 112.

[0055] In this application, the glove machine includes a needle selector 1 and a needle plate assembly 2, with the needle plate assembly 2 positioned above the needle selector 1. The needle selector 1 contains multiple magnetic rod assemblies 11, and the needle plate assembly 2 contains multiple spring needles 21. The number of spring needles 21 corresponds to the number of magnetic rod assemblies 11, meaning there is a one-to-one correspondence between the multiple spring needles 21 and the multiple magnetic rod assemblies 11. The corresponding magnetic rod assembly 11 attracts or releases the corresponding spring needle 21, thereby achieving needle selection in this glove machine.

[0056] In this application, the magnetic rod assembly 11 includes a first magnetic rod 111 and a second magnetic rod 112, which are spaced apart. The first magnetic rod 111 is magnetized so that its tip forms a north pole (N pole), and the second magnetic rod 112 is magnetized so that its tip forms a south pole (S pole). For a single spring needle 21, the magnetic attraction force generated by the first magnetic rod 111 and the second magnetic rod 112 can simultaneously attract the corresponding spring needle 21.

[0057] Because the magnetic field lines of a magnet run from the N pole to the S pole outside the magnet and from the S pole to the N pole inside the magnet, and in existing technologies, the magnetic rod assembly 11 of the needle selector 1 used for a single spring needle 21 all share the same magnetic pole. Therefore, outside the magnetic rod, the magnetic field lines propagate from the N pole to the S pole in the air. Magnetic field lines propagating in the air have scattered loops and significant energy loss, making them prone to interference with the magnetic fields of surrounding magnetic rods. This also reduces the magnetic attraction of the magnetic rod to the corresponding spring needle 21, potentially leading to needle selection errors, knitting errors, and reduced production efficiency.

[0058] In this application, the top of the first magnetic rod 111 is N pole after being magnetized, and the top of the second magnetic rod 112 is S pole after being magnetized. When the first magnetic rod 111 and the second magnetic rod 112 simultaneously attract the corresponding spring needle 21, the spring needle 21 conducts the connection between the top of the first magnetic rod 111 and the top of the second magnetic rod 112.

[0059] In this embodiment, the first magnetic rod 111, the second magnetic rod 112, and the spring needle 21 are all made of soft magnetic material. Since air is a non-magnetic medium, its magnetic reluctance is much greater than that of soft magnetic material. Similar to electric current, magnetic field lines always follow the path of least magnetic reluctance (maximum permeability). Therefore, outside the first magnetic rod 111 and the second magnetic rod 112, most of the magnetic field lines propagate from the N pole to the S pole in the spring needle 21.

[0060] On the one hand, it can prevent the magnetic field lines propagating outside the first magnetic rod 111 and the second magnetic rod 112 from becoming scattered, thereby reducing magnetic field interference with the surrounding magnetic rod assembly 11; on the other hand, since the magnetic reluctance of the spring needle 21 is much smaller than that of air, the energy loss of the magnetic field lines propagating in the spring needle 21 is small, thereby enhancing the attraction force of the first magnetic rod 111 and the second magnetic rod 112 on the corresponding spring needle 21, thus ensuring the accuracy of needle selection and improving production efficiency.

[0061] In this application, the magnetic rod assembly 11 further includes a first coil 113 and a second coil 114. The first coil 113 is disposed on the first magnetic rod 111, and the second coil 114 is disposed on the second magnetic rod 112. As mentioned above, the first magnetic rod 111 and the second magnetic rod 112 are made of soft magnetic material. Therefore, after the first magnetic rod 111 and the second magnetic rod 112 are magnetized, they can simultaneously generate a magnetic attraction force on the corresponding spring needle 21, causing the spring needle 21 to move and undergo elastic deformation, thereby attracting the spring needle 21 to the top of the first magnetic rod 111 and the second magnetic rod 112.

[0062] When the first coil 113 is energized, the magnetic field formed in the first coil 113 has magnetic field lines in the opposite direction to the magnetic field lines inside the first magnetic rod 111 after it is magnetized. Therefore, the magnetic field formed in the first coil 113 cancels out the magnetic field after the first magnetic rod 111 is magnetized, thereby reducing the magnetic field strength of the first magnetic rod 111 and demagnetizing the first magnetic rod 111.

[0063] When the second coil 114 is energized, the magnetic field formed in the second coil 114 has magnetic field lines in the opposite direction to the magnetic field lines inside the second magnetic rod 112 after it is magnetized. Therefore, the magnetic field formed in the second coil 114 cancels out the magnetic field after the second magnetic rod 112 is magnetized, thereby reducing the magnetic field strength of the second magnetic rod 112 and demagnetizing the second magnetic rod 112.

[0064] When the magnetic attraction force of the first magnetic rod 111 and the second magnetic rod 112 on the spring needle 21 is less than the elastic force required for the spring needle 21 to recover its deformation, the first magnetic rod 111 and the second magnetic rod 112 release the attracted spring needle 21, allowing the spring needle 21 to return to its original shape. Therefore, in this application, by attracting or releasing the corresponding spring needle 21 with the first magnetic rod 111 and the second magnetic rod 112, the position of the corresponding spring needle 21 changes, thereby realizing the needle selection of this glove machine.

[0065] In one embodiment, initially, the first magnetic rod 111 and the second magnetic rod 112 do not attract the corresponding spring needle 21, and the spring needle 21 is in a non-working position. When selecting a needle, the first magnetic rod 111 and the second magnetic rod 112 attract the corresponding spring needle 21, causing the spring needle 21 to move from the non-working position to the working position for knitting. After the work is completed, the first coil 113 and the second coil 114 are energized, and the first magnetic rod 111 and the second magnetic rod 112 release the corresponding spring needle 21, causing the spring needle 21 to return to the non-working position and wait for the next knitting operation.

[0066] In another embodiment, initially, the first magnetic rod 111 and the second magnetic rod 112 attract the corresponding spring needle 21, at which time the spring needle 21 is in a non-working position; when selecting a needle, the first coil 113 and the second coil 114 are energized, and the first magnetic rod 111 and the second magnetic rod 112 release the corresponding spring needle 21, causing the spring needle 21 to move from the non-working position to the working position for knitting; after the work is completed, the first coil 113 and the second coil 114 are de-energized, and the first magnetic rod 111 and the second magnetic rod 112 attract the corresponding spring needle 21, causing the spring needle 21 to return to the non-working position, waiting for the next knitting operation.

[0067] In this embodiment, the magnetic rod assembly 11 further includes a magnetic rod base 115 and a permanent magnet 116. The permanent magnet 116 is disposed in the magnetic rod base 115. The first magnetic rod 111 and the second magnetic rod 112 are spaced apart on the magnetic rod base 115, and the permanent magnet 116 is disposed between the first magnetic rod 111 and the second magnetic rod 112.

[0068] Since the bottom end of the first magnetic rod 111 is in contact with the N pole of the permanent magnet 116, and the bottom end of the second magnetic rod 112 is in contact with the S pole of the permanent magnet 116, the first magnetic rod 111 and the second magnetic rod 112 are magnetized by the permanent magnet 116. The top of the first magnetic rod 111 is the N pole and the top of the second magnetic rod 112 is the S pole. Thus, the corresponding spring needle 21 is attracted by the magnetic attraction force generated by the first magnetic rod 111 and the second magnetic rod 112.

[0069] After the first magnetic rod 111 and the second magnetic rod 112 are magnetized by the permanent magnet 116, it is equivalent to the first magnetic rod 111 extending the N pole of the permanent magnet 116 and the second magnetic rod 112 extending the S pole of the permanent magnet 116. That is, the first magnetic rod 111, the permanent magnet 116 and the second magnetic rod 112 are regarded as a whole magnet, with the first magnetic rod 111 being the N pole of the magnet and the second magnetic rod 112 being the S pole of the magnet.

[0070] The magnetic field lines of this magnet run from the N pole to the S pole outside the magnet. That is, outside the magnet, the magnetic field lines propagate through the air from the tip of the first magnetic rod 111 to the tip of the second magnetic rod 112. When the first magnetic rod 111 and the second magnetic rod 112 attract the spring needle 21, the spring needle 21 connects the tip of the first magnetic rod 111 to the tip of the second magnetic rod 112, thus connecting the N pole and S pole of the entire magnet.

[0071] Since the magnetic reluctance of the spring needle 21 is much smaller than that of air, the magnetic field lines outside the magnet preferentially choose the path of least magnetic reluctance. Therefore, most of the magnetic field lines propagate from the N pole to the S pole in the spring needle 21. This not only prevents the magnetic field line loops outside the magnet from becoming scattered and reduces mutual interference with the surrounding magnetic field, but also reduces the energy loss of the magnetic field lines, enhances the attraction force of the first magnetic rod 111 and the second magnetic rod 112 on the spring needle 21, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0072] In this embodiment, the magnetic rod assembly 11 further includes an isolation plate 117, which is disposed between the first magnetic rod 111 and the second magnetic rod 112. Specifically, the isolation plate 117 is disposed at the end of the first magnetic rod 111 and the second magnetic rod 112 away from the permanent magnet 116, that is, the isolation plate 117 is disposed near the top of the first magnetic rod 111 and the second magnetic rod 112, thereby isolating the end of the first magnetic rod 111 and the second magnetic rod 112 away from the permanent magnet 116. It is foreseeable that in actual implementation, the isolation plate 117 can be made of a non-magnetic material, such as copper, aluminum, stainless steel, etc., so that the isolation plate 117 can isolate the first magnetic rod 111 and the second magnetic rod 112.

[0073] In this application, the reason for isolating the ends of the first magnetic rod 111 and the second magnetic rod 112 away from the permanent magnet 116 by means of the isolation plate 117 is to prevent the ends of the first magnetic rod 111 and the second magnetic rod 112 away from the permanent magnet 116 from directly contacting each other. This prevents magnetic field lines from propagating from the position where the first magnetic rod 111 and the second magnetic rod 112 are in direct contact to the second magnetic rod 112 outside the overall magnet formed by the permanent magnet 116, the first magnetic rod 111 and the second magnetic rod 112. This reduces the magnetic field lines propagating from the spring needle 21, thereby enhancing the attraction force of the first magnetic rod 111 and the second magnetic rod 112 on the spring needle 21.

[0074] In this embodiment, both the first magnetic rod 111 and the second magnetic rod 112 extend vertically and are spaced apart. The bottom end of the first magnetic rod 111 contacts the N pole of the permanent magnet 116, so that the first magnetic rod 111 is magnetized by the permanent magnet 116, causing the N pole of the permanent magnet 116 to extend vertically upward. The bottom end of the second magnetic rod 112 contacts the S pole of the permanent magnet 116, so that the second magnetic rod 112 is magnetized by the permanent magnet 116, causing the S pole of the permanent magnet 116 to extend vertically upward.

[0075] A first contact surface 1111 is provided at the top of the first magnetic rod 111, and a second contact surface 1121 is provided at the top of the second magnetic rod 112. Outside the integral magnet formed by the permanent magnet 116, the first magnetic rod 111, and the second magnetic rod 112, magnetic field lines propagate in the air from the first contact surface 1111 to the second contact surface 1121.

[0076] When the first magnetic rod 111 and the second magnetic rod 112 attract the spring needle 21, the first contact surface 1111 and the second contact surface 1121 simultaneously come into contact with the spring needle 21. This allows the first contact surface 1111 and the second contact surface 1121 to be connected through the spring needle 21, enabling the magnetic field lines propagating from the first contact surface 1111 to the second contact surface 1121 to propagate within the spring needle 21. This reduces the dispersion of the magnetic field lines, decreases mutual interference with the surrounding magnetic field, reduces energy loss of the magnetic field lines, and enhances the attraction force of the first magnetic rod 111 and the second magnetic rod 112 on the spring needle 21.

[0077] In this application, the first contact surface 1111 and the second contact surface 1121 are disposed on the same horizontal plane. As mentioned above, when the first magnetic rod 111 and the second magnetic rod 112 attract the spring needle 21, the first contact surface 1111 and the second contact surface 1121 simultaneously contact the spring needle 21.

[0078] Therefore, in this application, the first contact surface 1111 and the second contact surface 1121 are set on the same horizontal plane so that when the first magnetic rod 111 and the second magnetic rod 112 attract the spring needle 21, the first contact surface 1111 and the second contact surface 1121 can better contact the spring needle 21, thereby making the spring needle 21 better conduct the first contact surface 1111 and the second contact surface 1121, further reducing the dispersion of magnetic field lines, enhancing the attraction force of the first magnetic rod 111 and the second magnetic rod 112 on the spring needle 21, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0079] In this embodiment, the first magnetic rod 111 includes a main body 1112, an inclined portion 1113, and an extension portion 1114. The main body 1112 is arranged parallel to and spaced apart from the second magnetic rod 112, and the extension portion 1114 is also arranged parallel to and spaced apart from the second magnetic rod 112. The inclined portion 1113 is disposed on the top of the main body 1112, and the extension portion 1114 is disposed on the top of the inclined portion 1113, thereby connecting the extension portion 1114 to the main body 1112 through the inclined portion 1113.

[0080] In this application, the main body 1112, the inclined part 1113 and the extension part 1114 are an integral structure. Therefore, after the bottom end of the main body 1112 contacts the N pole of the permanent magnet 116, the first magnetic rod 111 is magnetized by the permanent magnet 116, and the top end of the extension part 1114 is N pole.

[0081] The first contact surface 1111 is disposed on the top of the extension 1114. The extension 1114 extends vertically upward from the top of the inclined portion 1113, so that the first contact surface 1111 and the second contact surface 1121 are on the same horizontal plane, thereby making the first contact surface 1111 and the second contact surface 1121 better contact with the spring pin 21.

[0082] Because the spring pin 21 is small in size, in order to prevent the first contact surface 1111 and the second contact surface 1121 from failing to make contact with different positions of the spring pin 21 at the same time, in this application, the inclined portion 1113 is inclined towards the second magnetic rod 112 at the top of the main body portion 1112, so that the distance between the extension portion 1114 and the second magnetic rod 112 is smaller than the distance between the main body portion 1112 and the second magnetic rod 112, thereby reducing the distance between the first contact surface 1111 and the second contact surface 1121, and ensuring that both the first contact surface 1111 and the second contact surface 1121 can make contact with different positions of the spring pin 21.

[0083] In practical implementation, the isolation plate 117 can be disposed between the extension portion 1114 and the second magnetic rod 112, so that the isolation plate 117 isolates the extension portion 1114 from the second magnetic rod 112, thereby isolating the first magnetic rod 111 and the second magnetic rod 112. Since the distance between the extension portion 1114 and the second magnetic rod 112 is smaller than the distance between the main body portion 1112 and the second magnetic rod 112, the thickness of the isolation plate 117 can be reduced by disposing of the isolation plate 117 between the extension portion 1114 and the second magnetic rod 112, thereby reducing production costs.

[0084] In this embodiment, the magnetic rod base 115 is provided with a first fixing cavity 1151 and a second fixing cavity 1152, which are spaced apart. When assembling the magnetic rod assembly 11, the bottom of the first magnetic rod 111 is inserted into the first fixing cavity 1151, and the bottom of the second magnetic rod 112 is inserted into the second fixing cavity 1152. Thus, the first magnetic rod 111 is fixed by the first fixing cavity 1151, and the second magnetic rod 112 is fixed by the second fixing cavity 1152, so that the first magnetic rod 111 and the second magnetic rod 112 are spaced apart on the magnetic rod base 115.

[0085] Since the N pole and S pole of the permanent magnet 116 are located at opposite ends of the permanent magnet 116, the first magnetic rod 111 and the second magnetic rod 112 are spaced apart on the magnetic rod base 115, so that the first magnetic rod 111 is in contact with the N pole of the permanent magnet 116 and the second magnetic rod 112 is in contact with the S pole of the permanent magnet 116, thereby forming a U-shaped integral magnet. The first magnetic rod 111 is the N pole of the magnet and the second magnetic rod 112 is the S pole of the magnet.

[0086] Therefore, by simultaneously attracting the spring needle 21 with the first magnetic rod 111 and the second magnetic rod 112, the attraction force on the spring needle 21 can be increased, and the magnetic field interference between multiple magnetic rod assemblies 11 can be reduced, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0087] In this embodiment, a third fixing cavity 1153 is also provided inside the magnetic rod base 115. The two ends of the third fixing cavity 1153 are respectively connected to the first fixing cavity 1151 and the second fixing cavity 1152. When assembling the magnetic rod assembly 11, the bottom of the first magnetic rod 111 is inserted into the first fixing cavity 1151, the bottom of the second magnetic rod 112 is inserted into the second fixing cavity 1152, and the permanent magnet 116 is disposed in the third fixing cavity 1153. Thus, the first magnetic rod 111 is fixed by the first fixing cavity 1151, the second magnetic rod 112 is fixed by the second fixing cavity 1152, and the permanent magnet 116 is fixed by the third fixing cavity 1153, so that the first magnetic rod 111 and the second magnetic rod 112 are spaced apart on the magnetic rod base 115, and the permanent magnet 116 is disposed between the first magnetic rod 111 and the second magnetic rod 112.

[0088] Since the two ends of the third fixed cavity 1153 are connected to the first fixed cavity 1151 and the second fixed cavity 1152 respectively, the bottom of the first magnetic rod 111 is inserted into the first fixed cavity 1151, the bottom of the second magnetic rod 112 is inserted into the second fixed cavity 1152, and the permanent magnet 116 is placed in the third fixed cavity 1153. When the permanent magnet 116 is placed in the third fixed cavity 1153, the N pole of the permanent magnet 116 is attached to the bottom of the first magnetic rod 111 at one end of the third fixed cavity 1153, and the S pole of the permanent magnet 116 is attached to the bottom of the second magnetic rod 112 at the other end of the third fixed cavity 1153, so that the first magnetic rod 111, the permanent magnet 116 and the second magnetic rod 112 form a U-shaped integral magnet.

[0089] In this embodiment, a first limiting plate 1115 is provided on the first magnetic rod 111, and a second limiting plate 1122 is provided on the second magnetic rod 112. When assembling the magnetic rod assembly 11, the permanent magnet 116 is first placed in the third fixing cavity 1153, and then the bottom of the first magnetic rod 111 is inserted into the first fixing cavity 1151, and the bottom of the second magnetic rod 112 is inserted into the second fixing cavity 1152, so that the first limiting plate 1115 on the first magnetic rod 111 and the second limiting plate 1122 on the second magnetic rod 112 both abut against the top of the permanent magnet 116. Therefore, the permanent magnet 116 is limited by the first limiting plate 1115 and the second limiting plate 1122, and the permanent magnet 116 is fixed in the third fixing cavity 1153.

[0090] Furthermore, when the first magnetic rod 111, the second magnetic rod 112, and the permanent magnet 116 are mounted on the magnetic rod base 115, the first limiting plate 1115 abuts against the top of the permanent magnet 116 at the N end, thereby increasing the contact area between the first magnetic rod 111 and the permanent magnet 116; and the second limiting plate 1122 abuts against the top of the permanent magnet 116 at the S end, thereby increasing the contact area between the second magnetic rod 112 and the permanent magnet 116. This enhances the magnetization effect of the first magnetic rod 111 and the second magnetic rod 112, and further enhances the attraction force of the first magnetic rod 111 and the second magnetic rod 112 on the spring needle 21, ensuring the accuracy of needle selection.

[0091] As mentioned in the previous embodiments: outside the integral magnet formed by the permanent magnet 116, the first magnetic rod 111, and the second magnetic rod 112, the magnetic field lines propagate from the top of the first magnetic rod 111 to the top of the second magnetic rod 112; while inside the integral magnet, after passing through the second magnetic rod 112, the permanent magnet 116, and the first magnetic rod 111 in sequence, the magnetic field lines propagate from the top of the second magnetic rod 112 to the top of the first magnetic rod 111, thereby forming a closed loop with the magnetic field lines outside the integral magnet.

[0092] Therefore, in this application, the internal magnetic field lines of the first magnetic rod 111 after being magnetized propagate from the bottom end to the top end of the first magnetic rod 111, and the internal magnetic field lines of the second magnetic rod 112 after being magnetized propagate from the top end to the bottom end of the second magnetic rod 112. That is, the internal magnetic field lines of the first magnetic rod 111 after being magnetized are from bottom to top, and the internal magnetic field lines of the second magnetic rod 112 after being magnetized are from top to bottom.

[0093] Therefore, in this embodiment, the first coil 113 is wound around the outer periphery of the first magnetic rod 111 from bottom to top, so that when the first coil 113 is energized, the magnetic field formed in the first coil 113 has a magnetic field line direction opposite to the direction of the internal magnetic field line of the first magnetic rod 111 after it is magnetized. This makes the magnetic field formed in the first coil 113 cancel each other out with the magnetic field of the first magnetic rod 111 after it is magnetized, reducing the magnetic field strength of the first magnetic rod 111, thereby achieving the demagnetization of the first magnetic rod 111.

[0094] The second coil 114 is wound from top to bottom around the outer circumference of the second magnetic rod 112. When the second coil 114 is energized, the magnetic field line direction of the magnetic field formed by the second coil 114 is opposite to the direction of the magnetic field line inside the second magnetic rod 112 after it is magnetized. This causes the magnetic field formed by the second coil 114 to cancel each other out with the magnetic field after the second magnetic rod 112 is magnetized, reducing the magnetic field strength of the second magnetic rod 112 and thus demagnetizing the second magnetic rod 112.

[0095] In actual implementation, the first coil 113 and the second coil 114 can be powered by the same power supply equipment or by two separate power supply equipment. In order to make the structure of the needle selector 1 more compact and reduce production costs, in this application, it is preferred that the first coil 113 and the second coil 114 be powered by the same power supply equipment.

[0096] Therefore, in this embodiment, the tail end of the first coil 113 is connected to the head end of the second coil 114, thereby connecting the first coil 113 and the second coil 114 in series; the head end of the first coil 113 is connected to the positive terminal of the power supply circuit, and the tail end of the second coil 114 is connected to the negative terminal of the power supply circuit, thereby forming a closed loop, so that the power supply circuit can simultaneously supply current to the first coil 113 and the second coil 114, thereby making the needle selector 1 more compact and reducing production costs.

[0097] Specifically, in actual implementation, the same enameled wire can be used to make the first coil 113 and the second coil 114, as well as to connect the first coil 113 and the second coil 114 in series. First, the enameled wire is spirally wound from bottom to top around the outer circumference of the first magnetic rod 111 to form the first coil 113. Then, at the top of the first coil 113, the enameled wire is pulled horizontally to the second magnetic rod 112 and spirally wound from top to bottom around the outer circumference of the second magnetic rod 112 to form the second coil 114, thus realizing the series connection of the first coil 113 and the second coil 114. Finally, the first end of the enameled wire is connected to the positive terminal of the power supply circuit, and the last end is connected to the negative terminal of the power supply circuit, thus forming a closed loop, so that the power supply circuit can simultaneously conduct current to the first coil 113 and the second coil 114.

[0098] Since the first end of the first coil 113 is located at the bottom of the first coil 113 and the tail end of the second coil 114 is located at the bottom of the second coil 114, it is easier to connect the first end of the first coil 113 to the positive terminal of the power supply circuit and the tail end of the second coil 114 to the negative terminal of the power supply circuit. This makes the implementation of the magnetic rod assembly 11 simpler and more convenient, and further improves production efficiency.

[0099] Since the tail end of the first coil 113 is located at the top of the first coil 113, and the head end of the second coil 114 is located at the top of the second coil 114, connecting the first coil 113 and the second coil 114 in series at the top of the first coil 113 and the top of the second coil 114 can reduce the use of enameled wire, thereby reducing production costs, and also make the series connection of the first coil 113 and the second coil 114 simpler, further making the implementation of the magnetic rod assembly 11 simpler and more convenient, and improving production efficiency.

[0100] Since the direction of the magnetic field lines formed in the energized coil is related to the direction of the current winding in the energized coil, it is worth noting in actual implementation that when the first coil 113 is wound from bottom to top around the outer circumference of the first magnetic rod 111 and the second coil 114 is wound from top to bottom around the outer circumference of the second magnetic rod 112, the direction of the current in the first coil 113 and the second coil 114 should be designed according to the right-hand screw rule so that the direction of the magnetic field lines formed in the first coil 113 and the second coil 114 is as described above.

[0101] In this embodiment, the tail end of the second coil 114 extends to the side where the head end of the first coil 113 is located. Specifically, the first coil 113 is first formed by spirally winding enameled wire from bottom to top around the outer periphery of the first magnetic rod 111; then, at the top of the first coil 113, the enameled wire is pulled horizontally to the second magnetic rod 112 and spirally wound from top to bottom around the outer periphery of the first coil 113 to form the second coil 114, thereby realizing the series connection of the first coil 113 and the second coil 114.

[0102] Finally, at the bottom of the formed second coil 114, the enameled wire is pulled horizontally to the first magnetic rod 111 so that the tail end and the head end of the enameled wire are on the same side. Therefore, connecting the head end of the enameled wire to the positive terminal of the power supply circuit and the tail end to the negative terminal of the power supply circuit on the same side makes the connection between the enameled wire and the power supply circuit simpler and more convenient, easier to implement, and the wiring of the power supply circuit is more regular, thus making the implementation of the magnetic rod assembly 11 simpler and more convenient, and further improving production efficiency.

[0103] Furthermore, in this embodiment, a wiring groove 1154 is provided on one side of the magnetic rod base 115. When the tail end of the second coil 114 extends to the side where the head end of the first coil 113 is located, the head end of the first coil 113 and the tail end of the second coil 114 are both routed through the wiring groove 1154. The wiring groove 1154 limits the head end of the first coil 113 and the tail end of the second coil 114, thereby making the wiring of the first coil 113 and the second coil 114 more regular, further simplifying and facilitating the implementation of the magnetic rod assembly 11 and improving production efficiency.

[0104] In this embodiment, the needle plate assembly 2 includes a first support plate 22, a second support plate 23, and a rotating shaft 24. The first support plate 22 and the second support plate 23 are arranged at intervals relative to each other, and the rotating shaft 24 is mounted between the first support plate 22 and the second support plate 23, thereby fixing the two ends of the rotating shaft 24 by the first support plate 22 and the second support plate 23 respectively, thus fixing the rotating shaft 24.

[0105] Multiple spring pins 21 are arranged side by side on the rotating shaft 24, thereby fixing the positions of the multiple spring pins 21 through the rotating shaft 24. As described above, when the magnetic rod assembly 11 attracts or releases the spring pins 21, the spring pins 21 are displaced, thereby switching the spring pins 21 between the working position and the non-working position.

[0106] Therefore, in this application, multiple spring needles 21 are arranged side by side on the rotating shaft 24 and rotatably connected to the rotating shaft 24. When the magnetic rod assembly 11 attracts the spring needles 21, the spring needles 21 rotate around the rotating shaft 24 and generate elastic deformation. When the magnetic rod assembly 11 releases the spring needles 21, the spring needles 21 rotate in the opposite direction around the rotating shaft 24 under the elastic force of restoring their own deformation, so that the spring needles 21 return to their initial position. This allows the spring needles 21 to switch between the working position and the non-working position, thereby realizing the needle selection of this glove machine.

[0107] Specifically, in this embodiment, the spring needle 21 includes an adsorption part 2111 and a deformation part 2112. A rotating hole 2113 is provided at the end of the adsorption part 2111 away from the needle selection seat 12. The rotating shaft 24 passes through the rotating holes 2113 of multiple adsorption parts 2111 simultaneously, so that the adsorption parts 2111 of multiple spring needles 21 are simultaneously rotatably connected to the rotating shaft 24.

[0108] The deformation part 2112 is located at the bottom of the adsorption part 2111. When the magnetic attraction force generated by the magnetic rod assembly 11 attracts the end of the adsorption part 2111 near the needle selection seat 12, the adsorption part 2111 rotates around the rotation axis 24, and the deformation part 2112 is compressed and deformed. When the magnetic attraction force generated by the magnetic rod assembly 11 decreases or disappears, the magnetic rod assembly 11 releases the end of the adsorption part 2111 near the needle selection seat 12. Under the elastic force of the deformation part 2112 restoring its own deformation, the adsorption part 2111 rotates in the opposite direction around the rotation axis 24 and returns to the initial position, thereby switching the adsorption part 2111 of the spring needle 21 between the working position and the non-working position, realizing the needle selection of this glove machine.

[0109] In this embodiment, the needle selector 1 includes a needle selector seat 12, and multiple magnetic rod assemblies 11 are arranged in at least two rows on the needle selector seat 12. The multiple magnetic rod assemblies 11 arranged in adjacent rows are staggered in sequence, so that the multiple magnetic rod assemblies 11 can attract or release their respective corresponding spring needles 21. During the process of the multiple magnetic rod assemblies 11 attracting or releasing their respective corresponding spring needles 21, the movement trajectories of all spring needles 21 do not overlap, thereby preventing mutual interference between spring needles 21, thus ensuring the accuracy of needle selection and improving production efficiency.

[0110] In this embodiment, the needle selection seat 12 is assembled from a first seat body 121 and a second seat body 122. A first half-cavity is provided in the first seat body 121, and a second half-cavity is provided in the second seat body 122. A first row of magnetic rod assemblies 11 are disposed in the first half-cavity, and a second row of magnetic rod assemblies 11 are disposed in the second half-cavity. The first row of magnetic rod assemblies 11 in the first half-cavity and the second row of magnetic rod assemblies 11 in the second half-cavity are staggered, so that when the first row of magnetic rod assemblies 11 and the second row of magnetic rod assemblies 11 attract or release the corresponding spring needles 21, the spring needles 21 will not interfere with each other.

[0111] Since the end of the spring needle 21 away from the first seat 121 is sleeved on the rotating shaft 24 through the rotating hole 2113, the spring needle 21 is rotatably connected to the rotating shaft 24, and the rotating shaft 24 fixes the position of the end of the spring needle 21 away from the first seat 121.

[0112] In this application, multiple magnetic rod assemblies 11 are arranged in at least two rows on the needle selection seat 12. Therefore, when the rotating shaft 24 is set on one side of the needle selection seat 12, the distance between it and each row of magnetic rod assemblies 11 is different. If all the spring needles 21 are set to the same length, it may be possible that a row of magnetic rod assemblies 11 that is far away from the rotating shaft 24 cannot attract the corresponding spring needle 21.

[0113] Taking a needle selection base 12 with two rows of magnetic rod assemblies 11, wherein the first row of magnetic rod assemblies 11 is located in the first half-cavity of the first base 121 and the second row of magnetic rod assemblies 11 is located in the second half-cavity of the second base 122 as an example, in this embodiment, the rotating shaft 24 is located on one side of the first base 121. It is foreseeable that the distance between the second row of magnetic rod assemblies 11 and the rotating shaft 24 is greater than the distance between the first row of magnetic rod assemblies 11 and the rotating shaft 24.

[0114] Therefore, in this application, the multiple spring pins 21 include multiple short pins 212 and multiple long pins 211. When the rotating shaft 24 fixes the ends of the multiple long pins 211 and multiple short pins 212 away from the first seat 121, the multiple short pins 212 extend above the first row of magnetic rod assembly 11, and the multiple long pins 211 extend above the second row of magnetic rod assembly 11.

[0115] Because the first row of magnetic rod assemblies 11 and the second row of magnetic rod assemblies 11 are staggered, multiple short needles 212 and multiple long needles 211 are arranged alternately, so that the multiple magnetic rod assemblies 11 in the first row can attract or release multiple short needles 212 respectively, and the multiple magnetic rod assemblies 11 in the second row can attract or release multiple long needles 211 respectively. This ensures that the multiple magnetic rod assemblies 11 set on the needle selection seat 12 can attract or release the corresponding spring needles 21, thereby realizing the needle selection of this glove machine.

[0116] Furthermore, in this embodiment, the bottom of both the first and second half-cavities are provided with a plurality of magnetic rod limiting grooves 1211. When the first row of magnetic rod assemblies 11 is disposed in the first half-cavity, the plurality of magnetic rod limiting grooves 1211 at the bottom of the first half-cavity respectively limit the bottom of the plurality of magnetic rod assemblies 11 in the first row; when the second row of magnetic rod assemblies 11 is disposed in the second half-cavity, the plurality of magnetic rod limiting grooves 1211 at the bottom of the second half-cavity respectively limit the bottom of the plurality of magnetic rod assemblies 11 in the second row.

[0117] Multiple magnetic rod protrusions 1212 are provided at the top of both the first and second half-cavities. When the first row of magnetic rod assemblies 11 is placed in the first half-cavity, the tops of the multiple magnetic rod assemblies 11 in the first row protrude through the multiple magnetic rod protrusions 1212 respectively.

[0118] When the second row of magnetic rod assemblies 11 is placed in the second half-cavity, the tops of the multiple magnetic rod assemblies 11 in the second row extend through multiple magnetic rod extension ports 1212, so that the tops of the first row of magnetic rod assemblies 11 in the first half-cavity and the tops of the second row of magnetic rod assemblies 11 in the second half-cavity can attract or release their respective corresponding spring needles 21, thereby realizing the needle selection of this glove machine.

[0119] In this application, a plurality of magnetic rod limiting grooves 1211 disposed at the bottom of the first half cavity are offset from a plurality of magnetic rod limiting grooves 1211 disposed at the bottom of the second half cavity; a plurality of magnetic rod protrusions 1212 disposed at the top of the first half cavity are offset from a plurality of magnetic rod protrusions 1212 disposed at the top of the second half cavity, thereby causing the first row of magnetic rod assemblies 11 disposed in the first half cavity to be offset from the second row of magnetic rod assemblies 11 disposed in the second half cavity.

[0120] Specifically, in actual implementation, when installing the magnetic rod assembly 11 in the first or second half-cavity, each magnetic rod limiting groove 1211 limits the magnetic rod base 115 of one magnetic rod assembly 11. The tops of the first magnetic rod 111 and the second magnetic rod 112 of each magnetic rod assembly 11 extend from a magnetic rod extension port 1212, so that the tops of the first magnetic rod 111 and the second magnetic rod 112 can simultaneously attract or release the corresponding spring pin 21.

[0121] In this application, one end of a plurality of magnetic rod protrusions 1212 located at the top of the first and second half cavities is open, and one end of a plurality of magnetic rod limiting grooves 1211 located at the bottom of the first and second half cavities is open.

[0122] When installing the first row of magnetic rod assemblies 11 in the first base 121 and the second row of magnetic rod assemblies 11 in the second base 122, the top of the magnetic rod assembly 11 is slidably inserted into the magnetic rod extension port 1212 through the opening of the magnetic rod extension port 1212, and the bottom of the magnetic rod assembly 11 is slidably inserted into the magnetic rod limiting groove 1211 through the opening of the magnetic rod limiting groove 1211. This makes the installation of the first row of magnetic rod assemblies 11 in the first base 121 and the second row of magnetic rod assemblies 11 in the second base 122 simpler and more convenient, thereby making the implementation of the needle selector 1 simpler and more convenient.

[0123] As mentioned in the previous embodiments, multiple magnetic rod assemblies 11 are arranged in at least two rows on the needle selection seat 12, and the multiple magnetic rod assemblies 11 arranged in adjacent rows are staggered. Therefore, it can be foreseen that in actual implementation, the first half cavity of the first seat 121 and the second half cavity of the second seat 122 are not limited to a single row of magnetic rod assemblies 11, but multiple rows of magnetic rod assemblies 11 can also be arranged.

[0124] Specifically, a multi-row magnetic rod limiting groove 1211 can be provided at the bottom of the first half-cavity to limit the bottom of the multi-row magnetic rod assembly 11. A multi-row magnetic rod extension port 1212 can be provided at the top of the first half-cavity for the top of the multi-row magnetic rod assembly 11 to extend out. The multi-row magnetic rod limiting groove 1211 at the bottom of the first half-cavity is offset, and correspondingly, the multi-row magnetic rod extension port 1212 at the top of the first half-cavity is also offset, thus the multi-row magnetic rod assembly 11 in the first half-cavity is offset. Similarly, a multi-row magnetic rod limiting groove 1211 can be provided at the bottom of the second half-cavity, and a multi-row magnetic rod extension port 1212 can be provided at the top, with the multi-row magnetic rod limiting groove 1211 and the multi-row magnetic rod extension port 1212 also offset.

[0125] It is worth noting that the multiple rows of magnetic rod assemblies 11 in the first half cavity are misaligned in the same direction. When the first seat 121 and the second seat 122 are assembled, the two adjacent rows of magnetic rod assemblies 11 at the junction of the first half cavity and the second half cavity are also misaligned, and the direction of misalignment is the same as the direction of misalignment of the multiple rows of magnetic rod assemblies 11 in the first half cavity. The other multiple rows of magnetic rod assemblies 11 in the second half cavity are all misaligned with the direction of misalignment of the row of magnetic rod assemblies 11 at the junction, thereby ensuring that the movement trajectories of all spring pins 21 do not overlap.

[0126] As mentioned in the previous embodiments, the first end of the first coil 113 and the tail end of the second coil 114 are both routed through the wiring groove 1154. The wiring groove 1154 limits the first end of the first coil 113 and the tail end of the second coil 114, thereby making the wiring of the first coil 113 and the second coil 114 more regular, further making the implementation of the magnetic rod assembly 11 simpler and more convenient, and improving production efficiency.

[0127] Furthermore, in this embodiment, each magnetic rod limiting groove 1211 has a wiring hole 1213 at its bottom, and the needle selector 1 also includes a control board 13, which is located at the bottom of the needle selector base 12. When the magnetic rod base 115 of the magnetic rod assembly 11 is inserted into the magnetic rod limiting groove 1211, the first end of the first coil 113 and the second end of the second coil 114, which are routed through the wiring groove 1154, pass through the wiring hole 1213 and are fixedly connected to the control board 13. Thus, the first ends of the first coil 113 and the second ends of the second coil 114 of all magnetic rod assemblies 11 are integrated on the control board 13, and finally led out through the control board 13 and connected to the positive and negative terminals of the power supply circuit. This makes the wiring of the needle selector 1 structure simpler and facilitates the implementation of the needle selector 1 structure.

[0128] In this application, the needle selector 1 also includes a housing 14, within which a cavity is provided. The needle selector seat 12 is disposed on the top of the housing 14 and is fixedly connected to the housing 14, thereby securing the needle selector seat 12 through the housing 14. Since the control plate 13 is disposed at the bottom of the needle selector seat 12, when the needle selector seat 12 is fixedly installed on the top of the housing 14, the control plate 13 is located within the cavity of the housing 14, thus protecting the control plate 13 from exposure and enhancing the structural safety of the needle selector 1.

[0129] The above-described contents can be implemented individually or in combination in various ways, and all such variations are within the protection scope of this utility model.
