Description

Technical Field

[0001] The present invention relates to the technical field of glove knitting machines, and in particular to a glove knitting machine capable of avoiding magnetic field interference. Background Art

[0002] As the name implies, a glove machine is used to knit gloves. The existing glove machine needle selectors mostly use electromagnetic needle selectors. Electromagnetic needle selectors are more and more widely used due to their simple structure and convenient use. Electromagnetic needle selectors are usually provided with a number of magnetic bar assemblies corresponding to the spring needles of the glove machine. By magnetizing or demagnetizing the corresponding magnetic bar assemblies, the corresponding spring needles are adsorbed or released, thereby achieving the purpose of needle selection.

[0003] In the prior art, for a single spring needle, the needle selector used in the glove machine has a single magnetic bar in its magnetic bar assembly, and a single magnetic pole. The magnetic flux line loop is stray, and the magnetic fields interfere with each other greatly. When the magnetic bar assembly attracts or releases the corresponding spring needle, it is easy to produce a large magnetic force effect on the surrounding magnetic bar assemblies and spring needles, which may lead to needle selection errors, and then cause knitting errors, affecting production efficiency.

[0033] The glove machine for avoiding magnetic field interference proposed by the present invention has the following beneficial effects: (1) After the first magnetic bar of the magnetic bar assembly of the glove machine is magnetized, the top end is an N pole, and after the second magnetic bar is magnetized, the top end is an S pole. The top end of the first magnetic bar is connected to the top end of the second magnetic bar through the spring needle, so that the magnetic flux lines outside the first magnetic bar and the second magnetic bar are transmitted in the spring needle, thereby reducing the magnetic field interference with the surrounding magnetic bar assemblies and reducing the energy loss of the magnetic flux lines, thereby ensuring the accuracy of needle selection and improving production efficiency; (2) The first magnetic bar of the glove machine is fitted with the N pole of the permanent magnet, and the second magnetic bar is fitted with the S pole of the permanent magnet. The first magnetic bar, the permanent magnet and the second magnetic bar are regarded as a whole magnet, the first magnetic bar is the N pole of the magnet, and the second magnetic bar is the S pole of the magnet.

The first contact surface and the second contact surface are on the same horizontal plane. When the first magnetic bar and the second magnetic bar adsorb the spring needle, the first contact surface and the second contact surface are better in 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 the magnetic flux lines, enhancing the adsorption force of the first magnetic bar and the second magnetic bar on the spring needle, thereby ensuring the accuracy of needle selection and improving production efficiency; (5) The first magnetic bar of the glove machine includes a main body, an inclined portion and an extension portion.

Therefore, the N pole of the permanent magnet fits with the bottom end of the first magnetic bar at one end of the third fixed cavity, and the S pole of the permanent magnet fits with the bottom end of the second magnetic bar at the other end of the third fixed cavity, so that the first magnetic bar, the permanent magnet and the second magnetic bar form a U-shaped integral magnet; (7) The first magnetic bar of the glove machine is provided with a first limit plate, and the second magnetic bar is provided with a second limit plate. The first limit plate abuts against the top of the permanent magnet, thereby increasing the contact area between the first magnetic bar and the permanent magnet; at the S end of the permanent magnet, the second limit plate abuts against the top of the permanent magnet, thereby increasing the contact area between the second magnetic bar and the permanent magnet, thereby enhancing the magnetization effect of the first magnetic bar and the second magnetic bar, and further enhancing the adsorption force of the first magnetic bar and the second magnetic bar on the spring needle, thereby ensuring the accuracy of needle selection; (8) The tail end of the first coil of the 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 electrode of the power supply circuit, and the tail end of the second coil is connected to the negative electrode of the power supply circuit, thereby forming a closed loop, so that the power supply circuit can pass current to the first coil and the second coil at the same time, thereby making the structure of the needle selector more compact and reducing the production cost; (9) The tail end of the second coil of the 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 located on the same side. Therefore, the head end of the first coil is connected to the positive pole of the power supply circuit on the same side, and the tail end of the second coil is connected to the negative pole of the power supply circuit. This makes the connection between the first coil and the second coil and the power supply circuit simpler and more convenient, and easy to implement. The wiring of the power supply circuit is more regular, thereby making the implementation of the magnetic bar assembly simpler and more convenient, and further improving production efficiency. (10) A wiring groove is provided on one side of the magnetic bar base of the 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 wiring groove. The head end of the first coil and the tail end of the second coil are limited by the wiring groove, so that the routing of the first coil and the second coil is more regular, further making the implementation of the magnetic bar assembly simpler and more convenient, thereby improving production efficiency; (11) The needle selector of the glove machine includes a needle selection seat, and a plurality of magnetic bar assemblies are arranged in at least two rows on the needle selection seat, and the plurality of magnetic bar assemblies arranged in two adjacent rows are arranged alternately in sequence, so that the plurality of magnetic bar assemblies can adsorb the spring needles corresponding to each other, or release the spring needles corresponding to each other, and in the process of the plurality of magnetic bar assemblies adsorbing or releasing the spring needles corresponding to each other, the movement trajectories of all the spring needles do not overlap, thereby preventing the spring needles from interfering with each other, thereby ensuring the accuracy of needle selection and improving production efficiency; (12) The needle selection seat of the glove machine is composed of a first seat body and a second seat body.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 12 A glove machine for avoiding magnetic field interference according to an embodiment of the present invention comprises a needle selector 1 and a needle plate assembly 2 arranged above the needle selector 1, wherein the needle selector 1 is provided with a plurality of magnetic bar assemblies 11, and the needle plate assembly 2 is provided with a plurality of spring needles 21 corresponding to the plurality of magnetic bar assemblies 11 one by one, the magnetic bar assembly 11 comprises a first magnetic bar 111 and a second magnetic bar 112 arranged at intervals, a first coil 113 arranged on the first magnetic bar 111, and a second coil 114 arranged on the second magnetic bar 112, the first magnetic bar 111 has an N pole at its top end after being magnetized, and the second magnetic bar 112 has an S pole at its top end after being magnetized, the first coil 113 and the second coil 114 have opposite current flow directions, the energized first coil 113 demagnetizes the first magnetic bar 111, and the energized second coil 114 demagnetizes the second magnetic bar 112.

[0039] In the present application, the glove machine includes a needle selector 1 and a needle plate assembly 2, wherein the needle plate assembly 2 is arranged above the needle selector 1. A plurality of magnetic bar assemblies 11 are arranged in the needle selector 1, and a plurality of spring needles 21 are arranged in the needle plate assembly 2, wherein the number of the spring needles 21 corresponds to the number of the magnetic bar assemblies 11, that is, the plurality of spring needles 21 correspond to the plurality of magnetic bar assemblies 11 one by one, and the corresponding spring needles 21 are adsorbed or released by the corresponding magnetic bar assemblies 11, thereby realizing the needle selection of the glove machine.

[0040] In the present application, the magnetic bar assembly 11 includes a first magnetic bar 111 and a second magnetic bar 112, and the first magnetic bar 111 and the second magnetic bar 112 are arranged at intervals, wherein the top end of the first magnetic bar 111 is an N pole after being magnetized, and the top end of the second magnetic bar 112 is an S pole after being magnetized. For a single spring pin 21, the magnetic attraction generated by the first magnetic bar 111 and the second magnetic bar 112 can simultaneously adsorb the corresponding spring pin 21.

[0041] Since the direction of the magnetic flux lines of the magnet is 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 the prior art, for a single spring needle 21, the magnetic rod assembly 11 of the needle selector 1 used has the same magnetic pole. Therefore, outside the magnetic rod, the magnetic flux lines propagate from the N pole to the S pole in the air, and the magnetic flux lines propagating in the air have stray loops and large energy losses, which are easy to interfere with the magnetic fields of the surrounding magnetic rods, and reduce the adsorption force of the magnetic rod on the corresponding spring needle 21, which may lead to needle selection errors, knitting errors, and affect production efficiency.

[0042] In the present application, the top of the first magnetic bar 111 is N-pole after being magnetized, and the top of the second magnetic bar 112 is S-pole after being magnetized. When the first magnetic bar 111 and the second magnetic bar 112 simultaneously adsorb the corresponding spring needle 21, the spring needle 21 connects the top of the first magnetic bar 111 with the top of the second magnetic bar 112.

[0043] In this embodiment, the first magnetic bar 111, the second magnetic bar 112 and the spring needle 21 are all made of soft magnetic materials. Since air is a non-magnetic medium, its magnetic resistance is much greater than that of soft magnetic materials, and similar to electric current, magnetic flux lines always take the path with the smallest magnetic resistance (maximum magnetic permeability), so outside the first magnetic bar 111 and the second magnetic bar 112, most of the magnetic flux lines propagate from the N pole to the S pole in the spring needle 21.

[0044] On the one hand, it can prevent the magnetic flux lines propagating outside the first magnetic bar 111 and the second magnetic bar 112 from being scattered, thereby reducing the magnetic field interference with the surrounding magnetic bar assemblies 11; on the other hand, since the magnetic resistance of the spring needle 21 is much smaller than the magnetic resistance of the air, the energy loss of the magnetic flux lines propagating in the spring needle 21 is small, thereby enhancing the adsorption force of the first magnetic bar 111 and the second magnetic bar 112 on the corresponding spring needle 21, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0045] In the present application, the magnetic bar assembly 11 further includes a first coil 113 and a second coil 114, wherein the first coil 113 is disposed on the first magnetic bar 111, and the second coil 114 is disposed on the second magnetic bar 112. As mentioned above, the first magnetic bar 111 and the second magnetic bar 112 are made of soft magnetic materials, so after the first magnetic bar 111 and the second magnetic bar 112 are magnetized, they can simultaneously generate magnetic attraction to the corresponding spring pin 21, causing the spring pin 21 to move and generate elastic deformation, thereby adsorbing the spring pin 21 on the top of the first magnetic bar 111 and the second magnetic bar 112.

[0046] When the first coil 113 is energized, the magnetic field formed in the first coil 113 has a magnetic flux line direction opposite to the internal magnetic flux line direction of the first magnetic bar 111 after magnetization. Therefore, the magnetic field formed in the first coil 113 and the magnetic field of the first magnetic bar 111 after magnetization cancel each other out, thereby reducing the magnetic field strength of the first magnetic bar 111 and achieving demagnetization of the first magnetic bar 111.

[0047] When the second coil 114 is energized, the magnetic field formed in the second coil 114 has a magnetic flux line direction opposite to the internal magnetic flux line direction of the second magnetic bar 112 after magnetization. Therefore, the magnetic field formed in the second coil 114 and the magnetic field of the second magnetic bar 112 after magnetization cancel each other out, thereby reducing the magnetic field strength of the second magnetic bar 112 and achieving demagnetization of the second magnetic bar 112.

[0048] When the magnetic attraction of the first magnetic bar 111 and the second magnetic bar 112 on the spring pin 21 is less than the elastic force of the spring pin 21 to restore its own deformation, the first magnetic bar 111 and the second magnetic bar 112 release the adsorbed spring pin 21 to restore the spring pin 21 to its original shape. Therefore, in the present application, the first magnetic bar 111 and the second magnetic bar 112 adsorb or release the corresponding spring pin 21 to change the position of the corresponding spring pin 21, thereby realizing the needle selection of the glove machine.

[0049] In one embodiment, initially, the first magnetic bar 111 and the second magnetic bar 112 do not adsorb the corresponding spring needle 21, and the spring needle 21 is in a non-working position; when selecting needles, the first magnetic bar 111 and the second magnetic bar 112 adsorb the corresponding spring needle 21, so that the spring needle 21 moves from the non-working position to the working position to perform weaving operations; after the work is completed, the first coil 113 and the second coil 114 are energized, and the first magnetic bar 111 and the second magnetic bar 112 release the corresponding spring needle 21, so that the spring needle 21 returns to the non-working position and waits for the next weaving operation.

[0050] In another embodiment, initially, the first magnetic bar 111 and the second magnetic bar 112 adsorb the corresponding spring needle 21, and the spring needle 21 is in the non-working position; when selecting the needle, the first coil 113 and the second coil 114 are energized, and the first magnetic bar 111 and the second magnetic bar 112 loosen the corresponding spring needle 21, so that the spring needle 21 moves from the non-working position to the working position to perform the weaving operation; after the work is completed, the first coil 113 and the second coil 114 are de-energized, and the first magnetic bar 111 and the second magnetic bar 112 adsorb the corresponding spring needle 21, so that the spring needle 21 returns to the non-working position and waits for the next weaving operation.

[0051] In this embodiment, the magnetic bar assembly 11 further includes a magnetic bar base 115 and a permanent magnet 116 . The permanent magnet 116 is disposed in the magnetic bar base 115 . The first magnetic bar 111 and the second magnetic bar 112 are spaced apart on the magnetic bar base 115 . The permanent magnet 116 is disposed between the first magnetic bar 111 and the second magnetic bar 112 .

[0052] Since the bottom end of the first magnetic bar 111 is in contact with the N pole of the permanent magnet 116, and the bottom end of the second magnetic bar 112 is in contact with the S pole of the permanent magnet 116, the first magnetic bar 111 and the second magnetic bar 112 are magnetized by magnetizing through the permanent magnet 116, and the top end of the first magnetic bar 111 is the N pole, and the top end of the second magnetic bar 112 is the S pole, so that the corresponding spring pin 21 is adsorbed by the magnetic attraction generated by the first magnetic bar 111 and the second magnetic bar 112.

[0053] After the first magnetic bar 111 and the second magnetic bar 112 are magnetized by the permanent magnet 116, it is equivalent to that the first magnetic bar 111 extends the N pole of the permanent magnet 116, and the second magnetic bar 112 extends the S pole of the permanent magnet 116, that is, the first magnetic bar 111, the permanent magnet 116 and the second magnetic bar 112 are regarded as a whole magnet, the first magnetic bar 111 is the N pole of the magnet, and the second magnetic bar 112 is the S pole of the magnet.

[0054] The direction of the magnetic flux lines of the magnet is from the N pole to the S pole outside the magnet, that is, outside the magnet, the magnetic flux lines are propagated in the air from the top of the first magnetic bar 111 to the top of the second magnetic bar 112. When the first magnetic bar 111 and the second magnetic bar 112 attract the spring needle 21, the spring needle 21 connects the top of the first magnetic bar 111 with the top of the second magnetic bar 112, that is, the spring needle 21 connects the N pole and the S pole of the whole magnet.

[0055] Since the magnetic resistance of the spring needle 21 is much smaller than that of the air, the magnetic flux lines preferentially select the path with the smallest magnetic resistance outside the magnet, so most of the magnetic flux lines are transmitted from the N pole to the S pole in the spring needle 21, thereby preventing the magnetic flux lines from being scattered outside the magnet and reducing mutual interference with the surrounding magnetic field, and reducing the energy loss of the magnetic flux lines, thereby enhancing the adsorption force of the first magnetic bar 111 and the second magnetic bar 112 on the spring needle 21, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0056] In this embodiment, the magnetic bar assembly 11 further includes a spacer 117, and the spacer 117 is disposed between the first magnetic bar 111 and the second magnetic bar 112. Specifically, the spacer 117 is disposed at one end of the first magnetic bar 111 and the second magnetic bar 112 away from the permanent magnet 116, that is, the spacer 117 is disposed at a position close to the top of the first magnetic bar 111 and the second magnetic bar 112, so that the spacer 117 isolates the first magnetic bar 111 and the second magnetic bar 112 from the permanent magnet 116. It is foreseeable that in actual implementation, the spacer 117 can be made of non-magnetic materials, such as copper, aluminum, stainless steel, etc., so that the spacer 117 can isolate the first magnetic bar 111 and the second magnetic bar 112.

[0057] In the present application, the reason why the first magnetic bar 111 and the second magnetic bar 112 are isolated at one end away from the permanent magnet 116 by the isolation sheet 117 is to prevent the first magnetic bar 111 and the second magnetic bar 112 from directly contacting each other at one end away from the permanent magnet 116, thereby preventing the magnetic flux lines from propagating from the position where the first magnetic bar 111 and the second magnetic bar 112 are in direct contact outside the overall magnet formed by the permanent magnet 116, the first magnetic bar 111 and the second magnetic bar 112 to the second magnetic bar 112, thereby reducing the magnetic flux lines propagating from the spring needle 21, and thereby enhancing the adsorption force of the first magnetic bar 111 and the second magnetic bar 112 on the spring needle 21.

[0058] In this embodiment, the first magnetic bar 111 and the second magnetic bar 112 both extend in the vertical direction and are arranged at intervals. The bottom end of the first magnetic bar 111 contacts the N pole of the permanent magnet 116, so that after the first magnetic bar 111 is magnetized by the permanent magnet 116, the N pole of the permanent magnet 116 is extended vertically upward; the bottom end of the second magnetic bar 112 contacts the S pole of the permanent magnet 116, so that after the second magnetic bar 112 is magnetized by the permanent magnet 116, the S pole of the permanent magnet 116 is extended vertically upward.

[0059] A first contact surface 1111 is provided at the top of the first magnetic bar 111, and a second contact surface 1121 is provided at the top of the second magnetic bar 112. Outside the integral magnet formed by the permanent magnet 116, the first magnetic bar 111 and the second magnetic bar 112, magnetic flux lines propagate from the first contact surface 1111 to the second contact surface 1121 in the air.

[0060] When the first magnetic bar 111 and the second magnetic bar 112 adsorb the spring pin 21, the first contact surface 1111 and the second contact surface 1121 are in contact with the spring pin 21 at the same time, so that the first contact surface 1111 and the second contact surface 1121 are connected through the spring pin 21, so that the magnetic flux lines transmitted from the first contact surface 1111 to the second contact surface 1121 are transmitted in the spring pin 21, thereby reducing the dispersion of the magnetic flux lines and the mutual interference with the surrounding magnetic field, reducing the energy loss of the magnetic flux lines, and enhancing the adsorption force of the first magnetic bar 111 and the second magnetic bar 112 on the spring pin 21.

[0061] In the present application, the first contact surface 1111 and the second contact surface 1121 are arranged on the same horizontal plane. As mentioned above, when the first magnetic bar 111 and the second magnetic bar 112 adsorb the spring pin 21, the first contact surface 1111 and the second contact surface 1121 contact the spring pin 21 at the same time.

[0062] Therefore, in the present application, the first contact surface 1111 and the second contact surface 1121 are arranged on the same horizontal plane so that when the first magnetic bar 111 and the second magnetic bar 112 adsorb the spring needle 21, the first contact surface 1111 and the second contact surface 1121 can better contact with the spring needle 21, so that the spring needle 21 can better connect the first contact surface 1111 with the second contact surface 1121, further reduce the dispersion of magnetic lines of force, enhance the adsorption force of the first magnetic bar 111 and the second magnetic bar 112 on the spring needle 21, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0063] In this embodiment, the first magnetic bar 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 bar 112. The extension portion 1114 is also arranged parallel to and spaced apart from the second magnetic bar 112. The inclined portion 1113 is arranged at the top of the main body 1112, and the extension portion 1114 is arranged at the top of the inclined portion 1113, so that the extension portion 1114 is connected to the main body 1112 through the inclined portion 1113.

[0064] In the present application, the main body 1112, the inclined portion 1113 and the extension portion 1114 are an integrated structure. Therefore, the bottom end of the main body 1112 contacts the N pole of the permanent magnet 116, so that after the first magnetic bar 111 is magnetized by the permanent magnet 116, the top end of the extension portion 1114 is the N pole.

[0065] The first contact surface 1111 is disposed at the top of the extension portion 1114 , and the extension portion 1114 extends vertically upward at 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, so that the first contact surface 1111 and the second contact surface 1121 can better contact with the spring pin 21 .

[0066] Since the size of the spring needle 21 is small, in order to prevent the first contact surface 1111 and the second contact surface 1121 from being unable to simultaneously contact different positions of the spring needle 21, in the present application, the inclined portion 1113 is inclined toward the second magnetic bar 112 at the top of the main body 1112, so that the distance between the extension portion 1114 and the second magnetic bar 112 is smaller than the distance between the main body 1112 and the second magnetic bar 112, thereby reducing the distance between the first contact surface 1111 and the second contact surface 1121, thereby ensuring that the first contact surface 1111 and the second contact surface 1121 can both contact different positions of the spring needle 21.

[0067] In actual implementation, the isolation sheet 117 can be disposed between the extension portion 1114 and the second magnetic bar 112, so that the isolation sheet 117 isolates the extension portion 1114 from the second magnetic bar 112, thereby isolating the first magnetic bar 111 from the second magnetic bar 112. Since the distance between the extension portion 1114 and the second magnetic bar 112 is smaller than the distance between the main body 1112 and the second magnetic bar 112, compared with the case where the isolation sheet 117 is disposed between the main body 1112 and the second magnetic bar 112, the thickness of the isolation sheet 117 can be reduced by disposing the isolation sheet 117 between the extension portion 1114 and the second magnetic bar 112, thereby reducing the production cost.

[0068] In this embodiment, a first fixing cavity 1151 and a second fixing cavity 1152 are provided in the magnetic bar base 115, and the first fixing cavity 1151 and the second fixing cavity 1152 are spaced apart. When assembling the magnetic bar assembly 11, the bottom of the first magnetic bar 111 is inserted into the first fixing cavity 1151, and the bottom of the second magnetic bar 112 is inserted into the second fixing cavity 1152, so that the first magnetic bar 111 is fixed by the first fixing cavity 1151, and the second magnetic bar 112 is fixed by the second fixing cavity 1152, so that the first magnetic bar 111 and the second magnetic bar 112 are spaced apart on the magnetic bar base 115.

[0069] Since the N pole and S pole of the permanent magnet 116 are respectively located at the two ends of the permanent magnet 116, the first magnetic bar 111 and the second magnetic bar 112 are spaced apart on the magnetic bar base 115 so that the first magnetic bar 111 is in contact with the N pole of the permanent magnet 116, and the second magnetic bar 112 is in contact with the S pole of the permanent magnet 116, thereby forming a U-shaped integral magnet with the first magnetic bar 111, the permanent magnet 116 and the second magnetic bar 112, wherein the first magnetic bar 111 is the N pole of the magnet, and the second magnetic bar 112 is the S pole of the magnet.

[0070] Therefore, by simultaneously adsorbing the spring needle 21 by the first magnetic bar 111 and the second magnetic bar 112 , the adsorption force on the spring needle 21 can be increased, and the magnetic field interference between the multiple magnetic bar assemblies 11 can be reduced, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0071] In this embodiment, a third fixed cavity 1153 is further provided in the magnetic bar base 115, and the two ends of the third fixed cavity 1153 are respectively connected to the first fixed cavity 1151 and the second fixed cavity 1152. When assembling the magnetic bar assembly 11, the bottom of the first magnetic bar 111 is inserted into the first fixed cavity 1151, the bottom of the second magnetic bar 112 is inserted into the second fixed cavity 1152, and the permanent magnet 116 is arranged in the third fixed cavity 1153, so that the first magnetic bar 111 is fixed by the first fixed cavity 1151, the second magnetic bar 112 is fixed by the second fixed cavity 1152, and the third fixed cavity 1153 is fixed to the permanent magnet 116, so that the first magnetic bar 111 and the second magnetic bar 112 are arranged at intervals on the magnetic bar base 115, and the permanent magnet 116 is arranged between the first magnetic bar 111 and the second magnetic bar 112.

[0072] Since the two ends of the third fixed cavity 1153 are respectively connected to the first fixed cavity 1151 and the second fixed cavity 1152, the bottom of the first magnetic bar 111 is inserted into the first fixed cavity 1151, and the bottom of the second magnetic bar 112 is inserted into the second fixed cavity 1152. When the permanent magnet 116 is arranged in the third fixed cavity 1153, the N pole of the permanent magnet 116 is in contact with the bottom of the first magnetic bar 111 at one end of the third fixed cavity 1153, and the S pole of the permanent magnet 116 is in contact with the bottom of the second magnetic bar 112 at the other end of the third fixed cavity 1153, so that the first magnetic bar 111, the permanent magnet 116 and the second magnetic bar 112 form a U-shaped integral magnet.

[0073] In this embodiment, a first limiting plate 1115 is provided on the first magnetic bar 111, and a second limiting plate 1122 is provided on the second magnetic bar 112. When assembling the magnetic bar assembly 11, the permanent magnet 116 is first placed in the third fixed cavity 1153, and then the bottom of the first magnetic bar 111 is respectively inserted into the first fixed cavity 1151, and the bottom of the second magnetic bar 112 is inserted into the second fixed cavity 1152, so that the first limiting plate 1115 on the first magnetic bar 111 and the second limiting plate 1122 on the second magnetic bar 112 are both in contact with the top of the permanent magnet 116, so that 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 fixed cavity 1153.

[0074] In addition, when the first magnetic bar 111, the second magnetic bar 112 and the permanent magnet 116 are installed on the magnetic bar base 115, at the N end of the permanent magnet 116, the first limiting plate 1115 abuts against the top of the permanent magnet 116, so that the contact area between the first magnetic bar 111 and the permanent magnet 116 can be increased; at the S end of the permanent magnet 116, the second limiting plate 1122 abuts against the top of the permanent magnet 116, so that the contact area between the second magnetic bar 112 and the permanent magnet 116 can be increased, thereby enhancing the magnetization effect of the first magnetic bar 111 and the second magnetic bar 112, and then enhancing the adsorption force of the first magnetic bar 111 and the second magnetic bar 112 on the spring needle 21, thereby ensuring the accuracy of needle selection.

[0075] In the previous embodiments, it is mentioned that outside the overall magnet formed by the permanent magnet 116, the first magnetic bar 111 and the second magnetic bar 112, the magnetic flux lines are propagated from the top of the first magnetic bar 111 to the top of the second magnetic bar 112; and inside the overall magnet, the magnetic flux lines pass through the second magnetic bar 112, the permanent magnet 116 and the first magnetic bar 111 in sequence, and then propagate from the top of the second magnetic bar 112 to the top of the first magnetic bar 111, thereby forming a closed loop with the magnetic flux lines outside the overall magnet.

[0076] Therefore, in the present application, the internal magnetic flux lines of the first magnetic bar 111 after magnetization are propagated from the bottom end of the first magnetic bar 111 to the top end of the first magnetic bar 111, and the internal magnetic flux lines of the second magnetic bar 112 after magnetization are propagated from the top end of the second magnetic bar 112 to the bottom end of the second magnetic bar 112, that is, the internal magnetic flux lines of the first magnetic bar 111 after magnetization are from bottom to top, and the internal magnetic flux lines of the second magnetic bar 112 after magnetization are from top to bottom.

[0077] Therefore, in this embodiment, the first coil 113 is wound around the outer circumference of the first magnetic bar 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 flux line direction opposite to the internal magnetic flux line direction of the first magnetic bar 111 after magnetization, so that the magnetic field formed in the first coil 113 and the magnetic field of the first magnetic bar 111 after magnetization cancel each other out, reducing the magnetic field strength of the first magnetic bar 111, thereby achieving demagnetization of the first magnetic bar 111.

[0078] The second coil 114 is wound around the outer circumference of the second magnetic bar 112 from top to bottom, so that when the second coil 114 is energized, the magnetic field formed by the second coil 114 has a magnetic flux line direction opposite to the internal magnetic flux line direction of the second magnetic bar 112 after magnetization, so that the magnetic field formed by the second coil 114 and the magnetic field of the second magnetic bar 112 after magnetization cancel each other out, reducing the magnetic field strength of the second magnetic bar 112, thereby achieving demagnetization of the second magnetic bar 112.

[0079] In actual implementation, the first coil 113 and the second coil 114 can use the same set of power supply equipment for current flow, or they can use two sets of power supply equipment for current flow. 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 use the same set of power supply equipment for current flow.

[0080] Therefore, in the present 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 pole of the power supply circuit, and the tail end of the second coil 114 is connected to the negative pole of the power supply circuit, thereby forming a closed loop, so that the power supply circuit can pass current to the first coil 113 and the second coil 114 at the same time, thereby making the structure of the needle selector 1 more compact and reducing the production cost.

[0081] 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 the series connection of the first coil 113 and the second coil 114, that is, the enameled wire is firstly spirally wound around the outer circumference of the first magnetic bar 111 from bottom to top to form the first coil 113; then, at the top of the first coil 113, the enameled wire is horizontally pulled to the second magnetic bar 112, and spirally wound around the outer circumference of the second magnetic bar 112 from top to bottom to form the second coil 114, thereby realizing the series connection of the first coil 113 and the second coil 114; finally, the head end of the enameled wire is connected to the positive pole of the power supply circuit, and the tail end is connected to the negative pole of the power supply circuit, thereby forming a closed loop, so that the power supply circuit can simultaneously pass current to the first coil 113 and the second coil 114.

[0082] Since the head 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 head end of the first coil 113 to the positive pole of the power supply circuit and the tail end of the second coil 114 to the negative pole of the power supply circuit, thereby making the implementation of the magnetic rod assembly 11 simpler and more convenient, and further improving production efficiency.

[0083] 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, the first coil 113 and the second coil 114 are connected in series at the top of the first coil 113 and the top of the second coil 114, which can not only reduce the use of enameled wire, thereby reducing production costs, but also make the series connection of the first coil 113 and the second coil 114 simpler, further making the implementation of the magnetic bar assembly 11 simpler and more convenient, thereby improving production efficiency.

[0084] Since the direction of the magnetic field lines of force formed in the energized coil is related to the winding direction of the current in the energized coil, it is worth noting that in actual implementation: when the first coil 113 is wound from bottom to top around the outer periphery of the first magnetic bar 111 and the second coil 114 is wound from top to bottom around the outer periphery of the second magnetic bar 112, it is necessary to design the connection direction of the current in the first coil 113 and the second coil 114 according to the right-hand screw rule, so that the direction of the magnetic field lines of force formed in the first coil 113 and the second coil 114 is the above-mentioned direction.

[0085] 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 formed by first winding the enameled wire in a spiral shape from bottom to top around the outer periphery of the first magnetic bar 111; then, at the top of the first coil 113, the enameled wire is horizontally pulled to the second magnetic bar 112, and then wound in a spiral shape 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; Finally, at the bottom of the formed second coil 114, the enameled wire is pulled horizontally to the first magnetic bar 111 so that the tail end and the head end of the enameled wire are on the same side. Therefore, the head end of the enameled wire is connected to the positive pole of the power supply circuit on the same side, and the tail end is connected to the negative pole of the power supply circuit. This can make the connection between the enameled wire and the power supply circuit simpler and more convenient, easier to implement, and the routing of the power supply circuit more regular, thereby making the implementation of the magnetic bar assembly 11 simpler and more convenient, further improving production efficiency.

[0086] 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 head end of the first coil 113 and the tail end of the second coil 114 are limited by the wiring groove 1154, so that the routing of the first coil 113 and the second coil 114 is more regular, which further makes the implementation of the magnetic rod assembly 11 simpler and more convenient, and improves production efficiency.

[0087] 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 relatively spaced apart, and the rotating shaft 24 is mounted between the first support plate 22 and the second support plate 23, so that the two ends of the rotating shaft 24 are fixed by the first support plate 22 and the second support plate 23 respectively, thereby realizing the fixation of the rotating shaft 24.

[0088] A plurality of spring pins 21 are arranged side by side on the rotating shaft 24, so that the positions of the plurality of spring pins 21 are fixed by the rotating shaft 24. As described above, when the magnetic bar assembly 11 attracts or releases the spring pin 21, the spring pin 21 is displaced, so that the spring pin 21 is switched between the working position and the non-working position.

[0089] Therefore, in the present application, a plurality of spring pins 21 are arranged side by side on the rotating shaft 24 and are rotatably connected to the rotating shaft 24, so that when the magnetic bar assembly 11 adsorbs the spring pins 21, the spring pins 21 rotate around the rotating shaft 24 and generate elastic deformation; when the magnetic bar assembly 11 releases the spring pins 21, the spring pins 21 rotate in the opposite direction around the rotating shaft 24 under the action of the elastic force to restore their own deformation, so that the spring pins 21 return to the initial position, and then the spring pins 21 are switched between the working position and the non-working position, thereby realizing the needle selection of the glove machine.

[0090] Specifically, in this embodiment, the spring needle 21 includes an adsorption portion 2111 and a deformation portion 2112. A rotating hole 2113 is provided at one end of the adsorption portion 2111 away from the needle selection seat 12. The rotating shaft 24 simultaneously penetrates the rotating holes 2113 of multiple adsorption portions 2111, so that the adsorption portions 2111 of multiple spring needles 21 are rotatably connected to the rotating shaft 24 at the same time.

[0091] The deformation part 2112 is arranged at the bottom of the adsorption part 2111. When the magnetic attraction force generated by the magnetic bar assembly 11 adsorbs the end of the adsorption part 2111 close to the needle selection seat 12, the adsorption part 2111 rotates around the rotating shaft 24, and the deformation part 2112 is compressed and deformed; when the magnetic attraction force generated by the magnetic bar assembly 11 decreases or disappears, the magnetic bar assembly 11 releases the end of the adsorption part 2111 close to the needle selection seat 12, and under the elastic force of the deformation part 2112 to restore its own deformation, the adsorption part 2111 rotates in the opposite direction around the rotating shaft 24 and returns to the initial position, so that the adsorption part 2111 of the spring needle 21 is switched between the working position and the non-working position, thereby realizing the needle selection of the glove machine.

[0092] In this embodiment, the needle selector 1 includes a needle selection seat 12, and a plurality of magnetic bar assemblies 11 are arranged in at least two rows on the needle selection seat 12, and the plurality of magnetic bar assemblies 11 arranged in two adjacent rows are staggered in sequence, so that the plurality of magnetic bar assemblies 11 can adsorb the corresponding spring needles 21, or release the corresponding spring needles 21, and in the process of the plurality of magnetic bar assemblies 11 adsorbing or releasing the corresponding spring needles 21, the movement trajectories of all the spring needles 21 do not overlap, thereby preventing mutual interference between the spring needles 21, thereby ensuring the accuracy of needle selection and improving production efficiency.

[0093] In this embodiment, the needle selection seat 12 is composed of a first seat body 121 and a second seat body 122. A first half cavity is provided in the first seat body 121, a second half cavity is provided in the second seat body 122, a first row of magnetic bar assemblies 11 are provided in the first half cavity, a second row of magnetic bar assemblies 11 are provided in the second half cavity, and the first row of magnetic bar assemblies 11 provided in the first half cavity are staggered with the second row of magnetic bar assemblies 11 provided in the second half cavity, so that when the first row of magnetic bar assemblies 11 and the second row of magnetic bar assemblies 11 adsorb or release the corresponding spring pins 21, the spring pins 21 will not interfere with each other.

[0094] Since the end of the spring pin 21 away from the first seat body 121 is sleeved on the rotating shaft 24 through the rotating hole 2113, the spring pin 21 is rotatably connected to the rotating shaft 24, and the rotating shaft 24 fixes the position of the end of the spring pin 21 away from the first seat body 121.

[0095] In the present application, multiple magnetic bar 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, there is a difference in the distance between it and each row of magnetic bar assemblies 11. If all spring needles 21 are set to the same length, it is possible that a row of magnetic bar assemblies 11 far away from the rotating shaft 24 cannot adsorb the corresponding spring needles 21.

[0096] Take the example of two rows of magnetic bar assemblies 11 being arranged on the needle selection seat 12, wherein the first row of magnetic bar assemblies 11 are arranged in the first half cavity of the first seat body 121, and the second row of magnetic bar assemblies 11 are arranged in the second half cavity of the second seat body 122. In this embodiment, the rotation axis 24 is arranged on one side of the first seat body 121, and it can be foreseen that the distance between the second row of magnetic bar assemblies 11 and the rotation axis 24 is greater than the distance between the first row of magnetic bar assemblies 11 and the rotation axis 24.

[0097] Therefore, in the present application, the multiple spring needles 21 include multiple short needles 212 and multiple long needles 211. When the rotating shaft 24 fixes one end of the multiple long needles 211 and the multiple short needles 212 away from the first base body 121, the multiple short needles 212 extend to the top of the first row of magnetic bar assemblies 11, and the multiple long needles 211 extend to the top of the second row of magnetic bar assemblies 11.

[0098] Since the first row of magnetic bar assemblies 11 and the second row of magnetic bar assemblies 11 are staggered, the multiple short needles 212 and the multiple long needles 211 are staggered, so that the multiple magnetic bar assemblies 11 in the first row can absorb or release the multiple short needles 212 respectively, and the multiple magnetic bar assemblies 11 in the second row can absorb or release the multiple long needles 211 respectively, thereby ensuring that the multiple magnetic bar assemblies 11 arranged on the needle selection seat 12 can absorb or release the corresponding spring needles 21, thereby realizing the needle selection of the glove machine.

[0099] Furthermore, in this embodiment, a plurality of magnetic rod limiting grooves 1211 are provided at the bottom of the first half cavity and the second half cavity. When the first row of magnetic rod assemblies 11 are provided 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 are provided 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.

[0100] A plurality of magnetic rod extension openings 1212 are provided at the top of the first half cavity and the second half cavity. When the first row of magnetic rod assemblies 11 are arranged in the first half cavity, the tops of the plurality of magnetic rod assemblies 11 in the first row extend out through the plurality of magnetic rod extension openings 1212 respectively.

[0101] When the second row of magnetic bar assemblies 11 are arranged in the second half cavity, the tops of the plurality of magnetic bar assemblies 11 in the second row extend out through the plurality of magnetic bar extension openings 1212 respectively, so that the tops of the first row of magnetic bar assemblies 11 in the first half cavity and the tops of the second row of magnetic bar assemblies 11 in the second half cavity can both adsorb their corresponding spring pins 21 or release their corresponding spring pins 21, thereby realizing the needle selection of the glove machine.

[0102] In the present application, a plurality of magnetic bar limiting grooves 1211 arranged at the bottom of the first half cavity are staggered with a plurality of magnetic bar limiting grooves 1211 arranged at the bottom of the second half cavity; a plurality of magnetic bar extension openings 1212 arranged at the top of the first half cavity are staggered with a plurality of magnetic bar extension openings 1212 arranged at the top of the second half cavity, thereby making the first row of magnetic bar assemblies 11 arranged in the first half cavity staggered with the second row of magnetic bar assemblies 11 arranged in the second half cavity.

[0103] Specifically, in actual implementation, when the magnetic bar assembly 11 is installed in the first half cavity or the second half cavity, each magnetic bar limiting groove 1211 limits the magnetic bar base 115 of a magnetic bar assembly 11, and the top of the first magnetic bar 111 and the second magnetic bar 112 of each magnetic bar assembly 11 extend from a magnetic bar extension port 1212, so that the top of the first magnetic bar 111 and the second magnetic bar 112 can simultaneously adsorb or release the corresponding spring needle 21.

[0104] In the present application, one end of the multiple magnetic bar extension openings 1212 arranged at the top of the first half cavity and the second half cavity is open, and one end of the multiple magnetic bar limiting grooves 1211 arranged at the bottom of the first half cavity and the second half cavity is open.

[0105] When installing the first row of magnetic bar assemblies 11 in the first seat body 121 and the second row of magnetic bar assemblies 11 in the second seat body 122, the top of the magnetic bar assembly 11 is slidably inserted into the magnetic bar extension port 1212 through the opening of the magnetic bar extension port 1212, and at the same time, the bottom of the magnetic bar assembly 11 is slidably inserted into the magnetic bar limiting groove 1211 through the opening of the magnetic bar limiting groove 1211, thereby making the installation of the first row of magnetic bar assemblies 11 in the first seat body 121 and the installation of the second row of magnetic bar assemblies 11 in the second seat body 122 simpler and more convenient, thereby making the implementation of the needle selector 1 simpler and more convenient.

[0106] In the previous embodiment, it is mentioned that the plurality of magnetic bar assemblies 11 are arranged in at least two rows on the needle selection seat 12, and the plurality of magnetic bar assemblies 11 arranged in two adjacent rows are arranged alternately in sequence. Therefore, it can be foreseen that in actual implementation, the first half cavity of the first seat body 121 and the second half cavity of the second seat body 122 are not limited to being provided with one row of magnetic bar assemblies 11, but multiple rows of magnetic bar assemblies 11 can also be provided.

[0107] Specifically, a plurality of rows of magnetic bar limiting grooves 1211 may be provided at the bottom of the first half cavity, for limiting the bottom of the plurality of rows of magnetic bar assemblies 11. A plurality of rows of magnetic bar extension openings 1212 may be provided at the top of the first half cavity, for allowing the top of the plurality of rows of magnetic bar assemblies 11 to extend out, and the plurality of rows of magnetic bar limiting grooves 1211 at the bottom of the first half cavity are staggered, and correspondingly, the plurality of rows of magnetic bar extension openings 1212 at the top of the first half cavity are also staggered, so that the plurality of rows of magnetic bar assemblies 11 arranged in the first half cavity are staggered. Similarly, a plurality of rows of magnetic bar limiting grooves 1211 may be provided at the bottom of the second half cavity, and a plurality of rows of magnetic bar extension openings 1212 may be provided at the top, and the plurality of rows of magnetic bar limiting grooves 1211 are staggered, and the plurality of rows of magnetic bar extension openings 1212 are also staggered.

[0108] It is worth noting that the multiple rows of magnetic bar assemblies 11 in the first half cavity have the same dislocation direction, and when the first seat body 121 and the second seat body 122 are assembled, the two adjacent rows of magnetic bar assemblies 11 at the junction of the first half cavity and the second half cavity are also dislocated, and the dislocation direction is also consistent with the dislocation direction of the multiple rows of magnetic bar assemblies 11 in the first half cavity, and the remaining multiple rows of magnetic bar assemblies 11 in the second half cavity are all consistent with the dislocation direction of a row of magnetic bar assemblies 11 at the junction, thereby ensuring that the movement trajectories of all spring needles 21 do not overlap.

[0109] In the previous embodiment, it is mentioned that the head end of the first coil 113 and the tail end of the second coil 114 are both routed through the routing groove 1154, and the head end of the first coil 113 and the tail end of the second coil 114 are limited by the routing groove 1154, so that the routing of the first coil 113 and the second coil 114 is more regular, further making the implementation of the magnetic bar assembly 11 simpler and more convenient, thereby improving production efficiency.

[0110] Furthermore, in the present embodiment, a wiring hole 1213 is provided at the bottom of each magnetic bar limiting groove 1211, and the needle selector 1 further comprises a control board 13, which is provided at the bottom of the needle selector seat 12. When the magnetic bar base 115 of the magnetic bar assembly 11 is inserted into the magnetic bar limiting groove 1211, the first end of the first coil 113 and the tail end of the second coil 114 that are routed through the wiring groove 1154 pass through the wiring hole 1213 and are fixedly connected to the control board 13, thereby integrating the first end of the first coil 113 and the tail end of the second coil 114 of all magnetic bar assemblies 11 on the control board 13, and finally leading out through the control board 13 and connecting to the positive and negative poles of the power supply circuit, thereby making the wiring of the structure of the present needle selector 1 simpler and facilitating the implementation of the structure of the present needle selector 1.

[0111] In the present application, the needle selector 1 further includes a housing 14, a cavity is provided in the housing 14, the needle selector seat 12 is provided at the top of the housing 14, and is fixedly connected to the housing 14, so that the needle selector seat 12 is fixed by the housing 14. Since the control board 13 is provided 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 board 13 is located in the cavity of the housing 14, so that the control board 13 is protected by the housing 14 to prevent the control board 13 from being exposed, thereby enhancing the safety of the structure of the needle selector 1.
