Description

Technical Field

[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 bars corresponding to the elastic needles of the glove machine. By magnetizing or demagnetizing the corresponding magnetic bars, the corresponding elastic needles are adsorbed or released, thereby achieving the purpose of needle selection.

[0003] Since multiple elastic needles of the glove machine are arranged side by side, the distance between two adjacent elastic needles is small for the fine needle machine. In order to set magnetic bars corresponding to multiple elastic needles one by one in the electromagnetic needle selector, it is difficult to arrange the magnetic bars in the electromagnetic needle selector according to the elastic needle spacing of the fine needle machine. If the size of the magnetic bars is made small and forced to be arranged, the magnetic force between the magnetic bars will be affected because the distance between the magnetic bars is too close.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0034] The present invention provides a glove machine needle selector, comprising a needle selection seat 1, a plurality of magnetic bar assemblies 2 corresponding to a plurality of elastic needles 4 of the glove machine, and a mounting frame 3 for mounting the plurality of magnetic bar assemblies 2 on the needle selection seat 1. When the magnetic bar assemblies 2 are magnetized, the corresponding elastic needles 4 are adsorbed, and when the magnetic bar assemblies 2 are demagnetized, the corresponding elastic needles 4 are released; the plurality of magnetic bar assemblies 2 are arranged in at least two rows on the needle selection seat 1, and the magnetic bar assemblies 2 arranged in two adjacent rows are arranged alternately, see Figure 1 .

[0035] In the present application, the glove machine needle selector comprises a needle selection seat 1, a plurality of magnetic bar assemblies 2 and a mounting frame 3. The plurality of magnetic bar assemblies 2 respectively correspond to the plurality of elastic needles 4 of the glove machine. The mounting frame 3 mounts the plurality of magnetic bar assemblies 2 on the needle selection seat 1, and the plurality of magnetic bar assemblies 2 are arranged in at least two rows on the needle selection seat 1. When the corresponding magnetic bar assembly 2 is magnetized, the corresponding elastic needle 4 is adsorbed; when the corresponding magnetic bar assembly 2 is demagnetized, the corresponding elastic needle 4 is released, thereby achieving the purpose of the glove machine needle selector to select needles.

[0036] Since the multiple magnetic bar assemblies 2 arranged in two adjacent rows are staggered in sequence, the distance between two adjacent magnetic bar assemblies 2 is increased, making it easier to arrange the multiple magnetic bar assemblies 2 in the needle selector and preventing the magnetic bar assemblies 2 from affecting each other by magnetic force.

[0037] Specifically, in actual production, two rows of magnetic bar assemblies 2 can be arranged on the needle selection seat 1, and the multiple magnetic bar assemblies 2 in the second row are arranged in a staggered manner with the multiple magnetic bar assemblies 2 in the first row; three rows of magnetic bar assemblies 2 can also be arranged on the needle selection seat 1, and the multiple magnetic bar assemblies 2 in the second row are arranged in a staggered manner with the multiple magnetic bar assemblies 2 in the first row, and the multiple magnetic bar assemblies 2 in the third row are arranged in a staggered manner with the multiple magnetic bar assemblies 2 in the second row, and the staggered arrangement direction of the multiple magnetic bar assemblies 2 in the third row is the same as that of the multiple magnetic bar assemblies in the second row. The direction of staggered arrangement of the components 2 is the same; four rows of magnetic bar assemblies 2 can also be set on the needle selection seat 1, and the multiple magnetic bar assemblies 2 in the second row are sequentially staggered with the multiple magnetic bar assemblies 2 in the first row, and the multiple magnetic bar assemblies 2 in the third row are sequentially staggered with the multiple magnetic bar assemblies 2 in the second row, and the multiple magnetic bar assemblies 2 in the fourth row are sequentially staggered with the multiple magnetic bar assemblies 2 in the third row, and the direction of staggered arrangement of the multiple magnetic bar assemblies 2 in the fourth row is the same as the direction of staggered arrangement of the multiple magnetic bar assemblies 2 in the third and second rows. By analogy, more rows of magnetic bar assemblies 2 can be set on the needle selection seat 1, which can be determined according to actual production needs.

[0038] In this embodiment, the magnetic rod assembly 2 includes a magnetic rod 21 and a power-on coil 22 wound multiple times around the outer side of the magnetic rod 21; when a magnetic flux line in the same direction as the magnetic rod 21 is formed in the power-on coil 22, the magnetic rod 21 is magnetized, and the magnetic rod 21 adsorbs the corresponding elastic pin 4; when a magnetic flux line in the opposite direction to the magnetic rod 21 is formed in the power-on coil 22, the magnetic rod 21 is demagnetized, and the magnetic rod 21 releases the corresponding elastic pin 4, see Figure 5 In the present application, the magnetic bar assembly 2 includes a magnetic bar 21 and a powered coil 22 . The magnetic bar 21 has a certain magnetism under normal conditions, and the magnetic directions of the multiple magnetic bars 21 are the same. The powered coil 22 is wound around the outer side of the magnetic bar 21 for multiple turns.

[0039] When the energized coil 22 is flowing, and the direction of the magnetic flux lines formed in the energized coil 22 is the same as the direction of the magnetic flux lines of the magnetic bar 21 itself, the energized coil 22 magnetizes the magnetic bar 21, thereby increasing the magnetic field strength of the magnetic bar 21, until the magnetic attraction of the magnetic bar 21 is greater than the resilience of the elastic pin 4, and the magnetic bar 21 adsorbs and fixes the corresponding elastic pin 4; when the energized coil 22 is flowing, and the direction of the magnetic flux lines formed in the energized coil 22 is opposite to the direction of the magnetic flux lines of the magnetic bar 21 itself, the magnetic field formed in the energized coil 22 and the magnetic field of the magnetic bar 21 itself cancel each other out, thereby reducing the magnetic field strength of the magnetic bar 21 and achieving demagnetization of the magnetic bar 21, until the magnetic attraction of the magnetic bar 21 is less than the resilience of the elastic pin 4, and the magnetic bar 21 releases the adsorbed corresponding elastic pin 4.

[0040] In this embodiment, an upper limit plate 23 is provided near the top of the magnetic bar 21, and a lower limit plate 24 is provided near the bottom of the magnetic bar 21. The upper limit plate 23 limits the top of the energized coil 22, and the lower limit plate 24 limits the bottom of the energized coil 22. Figure 5 In the present application, an upper limit plate 23 is provided near the top of the magnetic bar 21, and a lower limit plate 24 is provided near the bottom of the magnetic bar 21. When the energized coil 22 is wound around the outside of the magnetic bar 21, it is located between the upper limit plate 23 and the lower limit plate 24, so that the energized coil 22 is limited by the upper limit plate 23 and the lower limit plate 24 to prevent the energized coil 22 from falling off the magnetic bar 21, thereby affecting the needle selection of the needle selector.

[0041] In this embodiment, the energized coil 22 includes two terminals 221 connected to the external circuit. The lower limit plate 24 is provided with wiring grooves 241 for routing the two terminals 221. The wiring grooves 241 are provided with wire bosses 242 for guiding the terminals 221. Figure 5 and Figure 6 In the present application, the energized coil 22 is provided with two terminals 221, which are connected to an external circuit, so that current is passed through the external circuit to the energized coil 22. When the current direction of the external circuit is changed, currents of different directions are passed through the energized coil 22, so that magnetic flux lines that are the same as or opposite to those of the magnetic bar 21 are formed in the energized coil 22.

[0042] Specifically, in the present application, the power coil 22 can be made of enameled wire. Two wiring grooves 241 are provided on the lower limit plate 24 at the bottom of the magnetic bar 21. When the two wiring terminals 221 of the power coil 22 are connected to the external circuit, the wiring is respectively carried out through the two wiring grooves 241, so that the two wiring terminals 221 of the power coil 22 are respectively limited by the two wiring grooves 241.

[0043] Since a plurality of magnetic bars 21 are arranged in the needle selector, each magnetic bar 21 is wound with a power-carrying coil 22 on the outside, and each power-carrying coil 22 is provided with two connection terminals 221 which need to be connected to the external circuit, the routing of the circuits in the needle selector is relatively complicated, and it is easy for the circuits to be entangled with and interfere with each other, which makes the assembly of the needle selector more difficult, affecting the processing efficiency, and affecting the service life of the circuits, thereby affecting the use of the needle selector.

[0044] Therefore, in the present application, the two terminal ends 221 of each energized coil 22 are routed in the two routing grooves 241 at the bottom of the magnetic bar 21, so that the terminal ends 221 of the energized coil 22 are limited by the routing grooves 241, so that the routing of multiple energized coils 22 in the needle selector is more regular, thereby making the assembly of the needle selector simpler and more convenient, easy to implement, and ensuring the normal use of the needle selector.

[0045] Furthermore, in the present application, a conductor boss 242 is provided in the wiring groove 241, and the conductor boss 242 may be an arc-shaped boss provided at the bottom of the wiring groove 241. When the terminal 221 of the energized coil 22 is routed in the wiring groove 241, the conductor boss 242 guides the terminal 221 of the energized coil 22 through the arc surface, so that when the routing direction of the terminal 221 of the energized coil 22 in the wiring groove 241 changes, a smooth transition is made through the guidance of the conductor boss 242, thereby preventing the terminal 221 of the energized coil 22 from being bent at a large angle, which affects the service life of the circuit.

[0046] In this embodiment, the mounting frame 3 is provided with a first accommodating cavity 31 for accommodating a plurality of magnetic bar assemblies 2. The top of the first accommodating cavity 31 is provided with at least two rows of staggered magnetic bar extension openings 32, and the bottom is provided with at least two rows of staggered magnetic bar exposure openings 33. The at least two rows of magnetic bar extension openings 32 are used to allow the tops of the plurality of magnetic bars 21 to extend out, and the at least two rows of magnetic bar exposure openings 33 are used to expose the bottoms of the plurality of magnetic bars 21, respectively. Figure 2 , Figure 3 and Figure 4 In the present application, a first accommodating cavity 31 for accommodating a plurality of magnetic bar assemblies 2 is provided in the mounting frame 3. At least two rows of staggered magnetic bar extension openings 32 are provided at the top of the first accommodating cavity 31, and at least two rows of staggered magnetic bar exposure openings 33 are provided at the bottom of the first accommodating cavity 31.

[0047] When at least two rows of staggered magnetic bar assemblies 2 are located in the first accommodating cavity 31, the tops of the plurality of magnetic bars 21 extend through the at least two rows of staggered magnetic bar extension openings 32 at the top of the first accommodating cavity 31, so that the magnetic bars 21 can adsorb or release the corresponding elastic pins 4; the bottoms of the plurality of magnetic bars 21 are exposed through the at least two rows of staggered magnetic bar exposure openings 33 at the bottom of the first accommodating cavity 31, so that the bottoms of the magnetic bars 21 can contact the outside world.

[0048] In this embodiment, the upper limit plate 23 abuts against the top of the first accommodating chamber 31 to prevent the magnetic bar 21 from moving upward in the first accommodating chamber 31, and the lower limit plate 24 abuts against the bottom of the first accommodating chamber 31 to prevent the magnetic bar 21 from moving downward in the first accommodating chamber 31, see Figure 2 and Figure 6Since an upper limit plate 23 is provided near the top of the magnetic bar 21, and a lower limit plate 24 is provided near the bottom of the magnetic bar 21, when at least two rows of staggered magnetic bar assemblies 2 are located in the first accommodating cavity 31, the upper limit plate 23 of each magnetic bar 21 abuts against the cavity wall at the top of the first accommodating cavity 31, thereby preventing the magnetic bar 21 from moving upward in the first accommodating cavity 31; the lower limit plate 24 of each magnetic bar 21 abuts against the cavity wall at the bottom of the first accommodating cavity 31, thereby preventing the magnetic bar 21 from moving downward in the first accommodating cavity 31, thereby fixing the distance between the magnetic bar 21 and the corresponding elastic pin 4, and ensuring that the magnetic bar 21 can adsorb the corresponding elastic pin 4.

[0049] In the present application, the mounting frame 3 can adopt a split structure composed of two clamping plates, so as to facilitate the fixed installation of multiple magnetic bar assemblies 2 in the mounting frame 3, and enhance the practicality of the needle selector. Specifically, a mounting fixing groove and a mounting fixing protrusion are provided at the corresponding positions on the top of the two clamping plates. When the two clamping plates are assembled, the mounting fixing groove of one clamping plate cooperates with the mounting fixing protrusion of the other clamping plate to form at least two rows of staggered magnetic bar extension openings 32 on the top of the mounting frame 3, and the cross-sectional area of ​​the formed magnetic bar extension opening 32 is larger than the cross-sectional area of ​​the top of the magnetic bar 21, and smaller than the cross-sectional area of ​​the upper limit plate 23.

[0050] Similarly, mounting and fixing grooves and mounting and fixing protrusions are also provided at corresponding positions at the bottom of the two clamps. When the two clamps are assembled, the mounting and fixing groove of one clamp is matched with the mounting and fixing protrusion of the other clamp, so that at least two rows of staggered magnetic bar exposure openings 33 are formed at the bottom of the mounting frame 3, and the cross-sectional area of ​​the formed magnetic bar exposure openings 33 is larger than the cross-sectional area of ​​the bottom of the magnetic bar 21, and smaller than the cross-sectional area of ​​the lower limit plate 24.

[0051] In this embodiment, the needle selector 1 is provided with a second accommodating cavity 11, and the top of the second accommodating cavity 11 is open, and the bottom of the mounting frame 3 can be inserted into the second accommodating cavity 11 through the top opening of the second accommodating cavity 11, see Figure 2 . A frame plate 34 is provided at both side ends of the mounting frame 3. When the bottom of the mounting frame 3 is inserted into the second accommodating cavity 11 and the two frame plates 34 abut against the top of the needle selection seat 1, the mounting frame 3 is mounted on the needle selection seat 1 through the two frame plates 34, so that the multiple magnetic bar assemblies 2 located in the first accommodating cavity 31 are mounted on the needle selection seat 1 through the mounting frame 3.

[0052] Specifically, in actual implementation, through holes can be set on the two side walls of the needle selection seat 1, and threaded holes can be set on the two side walls of the mounting frame 3. When the two frame plates 34 mount the mounting frame 3 on the needle selection seat 1, one end of the bolt can pass through the through hole of the side wall of the needle selection seat 1 and then be screwed to the threaded hole of the side wall of the mounting frame 3, so that the mounting frame 3 is fixedly installed on the needle selection seat 1.

[0053] In this embodiment, the needle selector further includes a permanent magnet 5 disposed in the second accommodating cavity 11, and a pressing plate 6 for fixing the permanent magnet 5 in the second accommodating cavity 11. When the mounting frame 3 is mounted on the needle selector seat 1, the bottoms of the plurality of magnetic bars 21 are in contact with the permanent magnet 5. Figure 2 In the present application, the needle selector further includes a permanent magnet 5 and a pressing plate 6 . The permanent magnet 5 is disposed in the second accommodating cavity 11 . The pressing plate 6 limits the position of the permanent magnet 5 and fixes the permanent magnet 5 in the second accommodating cavity 11 .

[0054] In the previous embodiment, it is mentioned that at least two rows of staggered magnetic bar exposure openings 33 are provided at the bottom of the first accommodating cavity 31. When at least two rows of staggered magnetic bar assemblies 2 are located in the first accommodating cavity 31, the bottoms of the magnetic bars 21 of the plurality of magnetic bar assemblies 2 are exposed through at least two rows of staggered magnetic bar exposure openings 33 at the bottom of the first accommodating cavity 31. Therefore, when the mounting frame 3 is fixedly mounted on the needle selection seat 1, the bottoms of the plurality of magnetic bars 21 exposed through the magnetic bar exposure openings 33 are all in contact with the permanent magnet 5, so that under the action of the permanent magnet 5, all the magnetic bars 21 have certain magnetism under normal conditions.

[0055] In this embodiment, the needle selector also includes a circuit board 7 disposed in the second accommodating cavity 11, and a support plate 8 disposed in the second accommodating cavity 11 for supporting the circuit board 7, and the support plate 8 sets the circuit board 7 in the second accommodating cavity 11; both side ends of the mounting frame 3 are provided with outlet holes 35 for allowing the wiring terminals 221 of the multiple energized coils 22 to extend out of the first accommodating cavity 31, and one end of the wiring terminals 221 of the multiple energized coils 22 extending out of the outlet holes 35 is respectively connected to the multiple wiring terminals of the circuit board 7, see Figure 2 and Figure 5 In the present application, the needle selector further includes a circuit board 7 and a support plate 8. The circuit board 7 is provided with a plurality of connection terminals. The support plate 8 supports the circuit board 7 and lifts the circuit board 7 away from the bottom cavity wall of the second accommodating cavity 11, thereby placing the circuit board 7 in the second accommodating cavity 11.

[0056] A plurality of outlet holes 35 are provided at both side ends of the mounting frame 3. After the wiring terminals 221 of the plurality of energized coils 22 are routed in the wiring groove 241, they extend out of the first accommodating cavity 31 through the plurality of outlet holes 35. When the plurality of magnetic bar assemblies 2 are located in the first accommodating cavity 31 and the mounting frame 3 is fixedly mounted on the needle selection seat 1, the ends of the wiring terminals 221 of the plurality of energized coils 22 extending out of the first accommodating cavity 31 are respectively connected to the plurality of wiring terminals on the circuit board 7, so that the circuit board 7 is energized to realize the flow of current through the plurality of energized coils 22.

[0057] In the present application, the reason why the mounting frame 3 is mounted on the needle selector seat 1 by abutting the top of the needle selector seat 1 through two frame plates 34 is to make the bottoms of the multiple magnetic bars 21 exposed through the magnetic bar exposure opening 33 just contact the permanent magnet 5 fixed in the second accommodating cavity 11; and the reason why the circuit board 7 is mounted in the second accommodating cavity 11 through the support plate 8 is to facilitate the connection of the wiring terminals 221 of the multiple energized coils 22 with the multiple wiring terminals on the circuit board 7 respectively, thereby making the assembly of the present needle selector simpler, more convenient and easier to implement.

[0058] Specifically, in actual implementation, the support plate 8 is a protrusion extending upward from the bottom wall of the second accommodating cavity 11, and the circuit board 7 is fixedly mounted on the support plate 8. The two ends of the circuit board 7 are supported by the two support plates 8, and the circuit board 7 is mounted in the second accommodating cavity 11, and a plurality of wiring terminals are arranged on the bottom surface of the circuit board 7. The pressing plate 6 is fixedly mounted above the circuit board 7, and the permanent magnet 5 is fixed in the pressing plate 6, so that the bottoms of the plurality of magnetic bars 21 exposed through the magnetic bar exposure opening 33 just contact with the permanent magnet 5 fixed in the second accommodating cavity 11.

[0059] In this embodiment, the needle selection seat 1 includes a shell 12 and a baffle plate 13. The shell 12 and the baffle plate 13 are assembled to form a second accommodating cavity 11. The baffle plate 13 is provided with a plug-in groove 131. The shell 12 is provided with a plug-in block 121 that is plugged into the plug-in groove 131. Figure 7 In the present application, the needle selector 1 is a split structure consisting of a shell 12 and a baffle plate 13, which are assembled to form a second accommodating chamber 11 with a top opening. A plug-in block 121 is provided on the shell 12, and a plug-in groove 131 is provided on the baffle plate 13.
