Description

Technical Field

[0001] The invention relates to the technical field of flat knitting machines, in particular to a needle guide triangle device suitable for bidirectional knitting of a rib part of a glove. Background Art

[0002] There are two types of glove knitting machines on the market, which are suitable for unidirectional knitting and bidirectional knitting of gloves. The basic working principle of unidirectional knitting is:

[0003] When knitting the main body of the cylindrical part of the glove, when the needle guide head moves from left to right, the needle guide triangle device on the rear needle guide head pushes up the knitting needle on the rear needle bed and eats the yarn in a yarn mouth to complete a knitting action; correspondingly, when the needle guide head moves from right to left, the needle guide triangle device in the front needle guide head pushes up the knitting needle on the front needle bed and relays the yarn in the same yarn mouth to complete another knitting action. Therefore, the needle guide head completes a reciprocating action from left to right and then back to left, which is called completing a knitting row. In this way, the yarn is knitted in a single spiral manner.

[0004] On this basis, in order to increase work efficiency, the inventor has previously applied for a Chinese invention patent with patent number CN202210035315.4, disclosing "a knitting glove machine front and rear heads synchronous yarn feeding and knitting mechanism and knitting method thereof". In this application, it is explained that the front and rear needle guide heads can respectively feed two yarns at the same time during the working process. In the same knitting horizontal row, by arranging the two needle guide heads in a staggered or side-by-side manner and reasonably adjusting the amplitude of the knitting needle descent, positive and reverse needle raising can be achieved (positive needle raising generally refers to that when the rear needle guide head moves from left to right, only the needle guide triangle device on the rear needle guide head pushes up the knitting needles on the rear needle bed, and the needle guide triangle device on the right needle guide head pushes up the knitting needles on the rear needle bed). When moving to the left, only the needle guide triangle device on the front needle guide head pushes up the knitting needles on the front needle bed, and the reverse needle raising means that when the rear needle guide head moves from left to right, the needle guide triangle device on the front needle guide head can also push up the knitting needles on the front needle bed, and when moving from right to left, the needle guide triangle device on the rear needle guide head can also push up the knitting needles on the rear needle bed). This can not only meet the requirements of sewing the fingertips and finger seams of the knitted gloves together, but also meet the requirements of not sewing together when knitting all other knitting horizontal rows, thereby achieving the knitting speed being nearly doubled without increasing the movement speed of the needle guide head, and greatly improving the production capacity. The two yarns in this equipment are woven together in a cross double helix manner.

[0005] At present, there are basically only two structures of the needle guide triangle device in the conventional knitting glove machine on the market. The following is a brief introduction to its working method when knitting the rib part:

[0006] The first type: only has the forward needle raising function, not the reverse needle raising function. In the forward needle raising process, the running track of the needle pin is: first rise along the slope of the elastic needle raising triangle to the highest point, then descend along the slope of the elastic density triangle to its bottom, then rise along the slope of the forward needle raising triangle to the highest point, then descend along the triangle track, descend to the position of the forward density triangle, and then continue to descend along the slope of the forward density triangle to its bottom, so as to complete a unidirectional weaving that first weaves the elastic and then the yarn.

[0007] The second type: It has both forward and reverse needle casting functions. This type of glove knitting machine is called jacquard glove machine or computer flat knitting machine in the industry. If reverse needle casting is performed after forward needle casting in the same knitting row, the running track of the needle pin is: after passing through the bottom of the elastic density triangle, it also passes through the bottom of the reverse density triangle to move.

[0008] Although the second working method mentioned above can realize reverse needle casting, it will inevitably increase the descending amplitude of the knitting needle that is engaged with the elastic thread, which will lead to the breakage of the elastic thread or the uncontrollable size and tightness of the ribbing part of the glove.

[0009] Therefore, the knitting glove machines in the industry generally do not implement the reverse needle-casting working method when knitting the ribbed parts. Even if reverse needle-casting is required, the following methods will be used:

[0010] 1. In the same knitting row where the reverse stitch is implemented, the elastic thread is not knitted (the industry term is called folding);

[0011] 2. If you need to take into account the knitting of the elastic thread during the reverse needle casting process, in order to prevent the elastic thread from breaking or affecting the knitting quality of the rib part, you can only significantly increase the reverse density triangle so that the bottom of the reverse density triangle and the bottom of the elastic density triangle reach the same height, so that the reverse density triangle will not change the falling amplitude of the knitting needle that has already eaten the elastic thread. However, this will result in a very high knitting density of the yarn in the knitting row, and normal knitting cannot be achieved.

[0012] In summary, ordinary glove knitting machines or flat knitting machines cannot normally realize both reverse cast-on knitting and elastic knitting in the same knitting row of the rib part, so they cannot be well adapted to the processing mode of bidirectional synchronous knitting, and cannot cooperate well to improve the processing efficiency of gloves. Summary of the invention

[0013] In order to solve the above problems, the present invention proposes a needle guide triangle device suitable for bidirectional knitting of the rib part of a glove.

[0014] The technical solution adopted by the present invention is: a needle guide cam device suitable for bidirectional knitting of the rib part of a glove, a needle guide cam device suitable for bidirectional knitting of the rib part of a glove, used to control the lifting and lowering movement of the needle feet of the knitting needles located in the front needle bed or the rear needle bed in the needle groove, the needle guide cam device is installed on the inner side of the needle guide head, and at least one head driving module is provided on the knitting machine for driving the two needle guide heads to perform reciprocating linear displacement on the front needle bed and the rear needle bed respectively, and, during the operation of the head driving module, the two The needle guide head has two relative position states: front-to-back symmetrical arrangement and front-to-back staggered arrangement. The running direction of the needle guide head slidably connected to the rear needle bed from left to right and the running direction of the needle guide head slidably connected to the front needle bed from right to left are set as the positive direction, and the running direction of the needle guide head slidably connected to the front needle bed from left to right and the running direction of the needle guide head slidably connected to the rear needle bed from right to left are set as the reverse direction. The two needle guide heads are set to go back and forth on the front needle bed or the rear needle bed once to form a knitting row. The needle guide triangle device includes:

[0015] A mounting plate, fixedly mounted on one side of the needle guide machine head;

[0016] A guide needle assembly is mounted on the mounting plate and includes an elastic guide needle structure and a yarn guide needle structure;

[0017] In one knitting row, the needle guide assembly located on the same needle guide head has two working states: forward needle raising and reverse needle raising, and both working states are completed once;

[0018] During the forward movement of the needle guide head, the yarn guide needle structure passes through the front needle bed or the rear needle bed before the elastic guide needle structure, completing the forward needle raising once. During the forward needle raising process, the needle guide assembly is used to cooperate with the knitting needle to weave the yarn first and then the elastic thread;

[0019] During the reverse running of the needle guide head, the elastic guide needle structure does not work, and the yarn guide needle structure passes through the front needle bed or the rear needle bed to complete the reverse needle raising once. During the reverse needle raising process, the needle guide assembly is used to cooperate with the knitting needle to weave in only the yarn but not the elastic thread.

[0020] To help understand, the following is a brief description of the role of the needle guide triangle device in a knitting glove machine or a knitting flat machine:

[0021] The needle guide triangle device is like a set of flat cams. The needle feet of the knitting needle can enter the groove of the cam, move the triangle, and force the knitting needle to make regular lifting and lowering movements in the needle groove of the front needle bed or the rear needle bed. Through the cooperation of the yarn feeding mechanism and the yarn mouth, the action of the needle hook and the needle tongue can be completed, and the yarn can be woven into a knitted fabric. During the rising process of the knitting needle, the coil gradually withdraws from the needle hook, opens the needle tongue, and withdraws the needle tongue and hangs on the needle bar; during the descent of the knitting needle, the needle hook hooks the newly placed yarn and pulls it to bend into a coil. At the same time, the original coil is out of the needle hook, and the new coil passes through the old coil and is connected in series with the old coil. The coil strings formed by numerous knitting needles are connected to each other to form a knitted fabric.

[0022] It should be noted that a knitting machine generally includes a frame, a head drive module is installed on the frame, a yarn mouth drive assembly is also installed on the frame, the yarn group drive assembly includes a number of guide rails arranged at intervals from each other, a single guide rail is provided with at least a pair of yarn mouths and a number of drive motors that respectively drive the yarn mouths to move back and forth on the guide rails, each yarn mouth is controlled by a separate drive motor to cooperate with the knitting needles to complete the action of weaving the yarn into a knitted fabric during the forward or reverse needle casting process, and the above actions can be controlled by a control mechanism installed on the frame.

[0023] If you want to reverse the needle casting when knitting the ribbed part of the gloves, the needle foot will pass through the bottom of the elastic density triangle during the forward knitting process and continue to move through the bottom of the reverse density triangle (this will cause the needle that has already eaten the elastic thread to descend further).

[0024] The needle guide triangle devices on the market all cooperate with the knitting needles to weave the elastic thread first and then the yarn when starting the needle in the forward direction. This application completely subverts the principle of other knitting gloves machines to weave the elastic thread first and then the yarn in a knitting row. Innovatively, the yarn is first woven into the elastic thread and then the elastic thread in a knitting row, so that in the knitting row of the ribbed part, when starting the needle in the forward direction, it first passes through the bottom of the reverse density triangle and then passes through the bottom of the elastic density triangle. Therefore, when starting the needle in the reverse direction, there is no situation that the descent range of the knitting needle that has already eaten the elastic thread will not be increased, and it will not cause the breakage of the elastic thread or the uncontrollable size and tightness of the glove rib part.

[0025] Several optional methods are also provided below, but they are not intended to be additional limitations on the above-mentioned overall solution, but are merely further supplements or preferences. Under the premise that there are no technical or logical contradictions, each optional method can be combined with the above-mentioned overall solution separately, and multiple optional methods can also be combined.

[0026] Preferably, the yarn guide needle structure includes a needle raising height control triangle, a positive needle raising triangle, a reverse needle raising triangle, a half needle triangle, a positive density triangle and a reverse density triangle, and the elastic guide needle structure includes an elastic needle raising triangle and an elastic density triangle, wherein:

[0027] The reverse density triangle is located at the rightmost side of the mounting plate;

[0028] The needle raising height control triangle is located at the upper left of the reverse density triangle;

[0029] The positive needle raising triangle is located at the lower right of the needle raising height control triangle, and the reverse density triangle is located at the upper right of the positive needle raising triangle;

[0030] The reverse needle raising triangle is located at the lower left of the needle raising height control triangle;

[0031] The elastic needle raising triangle is located on the left side of the reverse needle raising triangle;

[0032] The elastic density triangle is located above the elastic starting triangle;

[0033] The forward density triangle is located at the upper left of the reverse needle raising triangle, and the elastic needle raising triangle is located at the lower left of the forward density triangle.

[0034] The left and right directions are determined based on the direction in which a person faces the knitting glove machine. Since the running direction of the needle guide head slidingly connected to the rear needle bed from left to right and the running direction of the needle guide head slidingly connected to the front needle bed from right to left have been defined as the positive direction, and the needle feet run in the positive direction when the needle is cast on in the positive direction, and the needle feet run in the reverse direction when the needle is cast on in the reverse direction. That is to say, when the needle is cast on in the positive direction, the running track of the needle feet is: the needle feet first rise along the inclined surface of the positive needle casting triangle, and when reaching the highest point (i.e., the needle casting height control triangle), they fall along the triangle track, and after falling to the position of the positive density triangle, they continue to fall along the inclined surface of the positive density triangle until they pass through the bottom of the positive density triangle, and then the needle feet rise along the inclined surface of the elastic band casting triangle, and after reaching the highest point, they fall along the inclined surface of the elastic band density triangle and pass through the bottom of the elastic band density triangle to complete a knitting row in which the yarn is first woven into the positive needle casting and then the elastic band is woven into the elastic band.

[0035] When the needle is cast on in the reverse direction, the trajectory of the needle foot is: the needle foot rises along the inclined surface of the reverse cast-on triangle, and when it reaches the highest point (i.e. the cast-on height control triangle), it descends along the triangle track, and when it descends to the position of the reverse density triangle, it continues to descend along the inclined surface of the reverse density triangle until it passes the bottom of the reverse density triangle, thereby completing a reverse cast-on knitting row in which only yarn is woven in but no elastic band is woven in.

[0036] The specific structural design of the yarn guide needle structure and the elastic guide needle structure mentioned above is only a preferred method after determining their functions and relative positions, so as to achieve the purpose of not causing the elastic thread to break during the reverse needle raising process. In actual processing and production, some detailed adjustments can also be made.

[0037] Preferably, the forward needle raising triangle is located on the right side of the reverse needle raising triangle, and the guide angles of the forward needle raising triangle and the reverse needle raising triangle have the same inclination.

[0038] Preferably, the yarn guide needle structure also includes a half needle triangle, the half needle triangle is located above the middle position of the forward needle raising triangle and the reverse needle raising triangle, and the needle raising height control triangle is located above the half needle triangle.

[0039] Preferably, the needle guide assembly further comprises a needle pressing triangle, and the needle pressing triangle is located on the left side of the elastic density triangle.

[0040] Preferably, a flat needle cam is provided above the press needle cam, and the flat needle cam is fixedly mounted on the mounting plate.

[0041] Here, the designs of the needle pressing triangle and the flat needle triangle are to cooperate to complete the needle guiding work of the knitting needle more stably. Since it is the existing technology, it will not be elaborated here.

[0042] More preferably, a clearance groove is provided on one side of the needle guide machine head, and one side of a portion of the needle guide assembly extends through the mounting plate and is embedded in the clearance groove.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] 1. By improving the needle guide triangle device, the glove knitting machine can simultaneously start the needle in the forward direction and the reverse direction when knitting the ribbed part of the glove, and the reverse start will not increase the downward range of the knitting needle that has been bitten into the elastic thread, which will not cause the breakage of the elastic thread or the uncontrollable size and tightness of the ribbed part of the glove;

[0045] 2. The overall structure is stable, which provides better technical support for the processing mode of bidirectional efficient knitting, so that the rib part of the gloves can also be knitted bidirectionally and quickly, greatly improving the production capacity of the knitting glove machine.

[0063] Specific implementation plan: see Figure 1-Figure 11The present invention is a needle guide triangle device 8 suitable for bidirectional knitting of the rib part of a glove, which is used to control the lifting and lowering movement of the needle feet of the knitting needles located in the front needle bed 6 or the rear needle bed 9 in the needle groove. The needle guide triangle device 8 is installed on the inner side of the needle guide head 7. The knitting machine is provided with at least one head driving module for driving the two needle guide heads 7 to perform reciprocating linear displacement on the front needle bed 6 and the rear needle bed 9 respectively, and during the operation of the head driving module, the two needle guide heads 7 have a front-to-back symmetrical arrangement and a front-to-back staggered arrangement. The two relative position states are arranged, and the running direction of the needle guide head 7 slidingly connected to the rear needle bed 9 from left to right and the running direction of the needle guide head 7 slidingly connected to the front needle bed 6 from right to left are set as the positive direction, and the running direction of the needle guide head 7 slidingly connected to the front needle bed 6 from left to right and the running direction of the needle guide head 7 slidingly connected to the rear needle bed 9 from right to left are set as the reverse direction, and the two needle guide heads 7 are set to go back and forth on the front needle bed 6 or the rear needle bed 9 respectively to form a knitting row, and the needle guide triangle device 8 includes:

[0064] The mounting plate 81 is fixedly mounted on one side of the needle guide head 7;

[0065] The guide needle assembly is mounted on the mounting plate 81 and includes an elastic guide needle structure and a yarn guide needle structure;

[0066] In a knitting row, the needle guide assembly located on the same needle guide head 7 has two working states: forward needle raising and reverse needle raising, and both working states are completed once;

[0067] During the forward movement of the needle guide head 7, the yarn guide needle structure passes through the front needle bed 6 or the rear needle bed 9 before the elastic guide needle structure, completing a forward needle raising process. During the forward needle raising process, the needle guide assembly cooperates with the knitting needle to weave the yarn first and then the elastic thread;

[0068] During the reverse operation of the needle guide head 7, the elastic needle guide structure does not work, and the yarn guide structure passes through the front needle bed 6 or the rear needle bed 9 to complete a reverse needle start-up. During the reverse needle start-up process, the needle guide assembly is used to cooperate with the knitting needle to weave in only the yarn but not the elastic thread.

[0069] To help understand, the following is a brief description of the role of the needle guide triangle device in a knitting glove machine or a knitting flat machine:

[0070] The needle guide triangle device 8 is like a set of flat cams. The needle feet of the knitting needle can enter the groove of the cam, move the triangle, and force the knitting needle to make regular lifting and lowering movements in the needle groove of the front needle bed 6 or the rear needle bed 9. Through the cooperation of the yarn feeding mechanism 4 and the yarn mouth 5, the action of the needle hook and the needle tongue 10 can be completed, and the yarn can be woven into a knitted fabric. During the rising process of the knitting needle, the coil gradually withdraws from the needle hook, opens the needle tongue 10, and withdraws the needle tongue 10 and hangs on the needle rod; during the descent of the knitting needle, the needle hook hooks the newly placed yarn and pulls it to bend into a coil, while the original coil is out of the needle hook, and the new coil passes through the old coil and is connected in series with the old coil. The coil strings formed by numerous knitting needles are connected to each other to form a knitted fabric.

[0071] Please note that, see Figure 8-Figure 11 The knitting machine generally includes a frame 1, a head drive module is installed on the frame 1, a yarn mouth drive assembly 3 is also installed on the frame 1, the yarn group drive assembly 3 includes a plurality of guide rails arranged at intervals from each other, a single guide rail is provided with at least a pair of yarn mouths 5 and a plurality of drive motors respectively driving the yarn mouths 5 to move back and forth on the guide rails, each yarn mouth 5 is controlled by a separate drive motor to cooperate with the knitting needles to complete the action of weaving the yarn into a knitted fabric during the forward or reverse needle casting process, and the above actions can be controlled by a control mechanism 2 installed on the frame 1.

[0072] If you want to reverse the needle casting when knitting the ribbed part of the glove, the needle foot will pass through the bottom of the elastic density triangle 83 during the forward knitting process and then continue to move through the bottom of the reverse density triangle 86 (this will cause the needle that has already eaten the elastic thread to descend further).

[0073] The needle guide triangle device 8 on the market first weaves the elastic thread and then the yarn when starting the needle in the forward direction. The present application completely overturns the principle of other knitting gloves knitting machines to first weave the elastic thread and then the yarn in a knitting row, and innovatively weaves the yarn first and then the elastic thread in a knitting row, so that in the knitting row of the ribbed part, when starting the needle in the forward direction, it first passes through the bottom of the reverse density triangle 86 and then passes through the bottom of the elastic density triangle 83. Therefore, when starting the needle in the reverse direction, there is no situation that the descent amplitude of the knitting needle that has already eaten the elastic thread will not be increased, and it will not cause the breakage of the elastic thread or the uncontrollable size and tightness of the glove rib part.

[0074] See also Figure 1-Figure 6 The yarn guide needle structure includes a needle raising height control triangle 85, a positive needle raising triangle 88, a reverse needle raising triangle 89, a half needle triangle 810, a positive density triangle 84 and a reverse density triangle 86, and the elastic guide needle structure includes an elastic needle raising triangle 87 and an elastic density triangle 83, wherein,

[0075] The reverse density triangle 86 is located on the far right side of the mounting plate 81;

[0076] The needle raising height control triangle 85 is located at the upper left of the reverse density triangle 86;

[0077] The positive needle raising triangle 88 is located at the lower right of the needle raising height control triangle 85, and the reverse density triangle 86 is located at the upper right of the positive needle raising triangle 88;

[0078] The reverse needle raising triangle 89 is located at the lower left of the needle raising height control triangle 85;

[0079] The elastic needle raising triangle 87 is located on the left side of the reverse needle raising triangle 89;

[0080] The elastic density triangle 83 is located above the elastic cast-on triangle 87;

[0081] The forward density triangle 84 is located at the upper left of the reverse needle raising triangle 89 , and the elastic needle raising triangle 87 is located at the lower left of the forward density triangle 84 .

[0082] The left and right directions are determined based on the direction in which a person faces the glove knitting machine. Since the running direction of the needle guide head 7 slidingly connected to the rear needle bed 9 from left to right and the running direction of the needle guide head 7 slidingly connected to the front needle bed 6 from right to left are defined as the positive direction, and the needles run in the positive direction when the needles are raised in the positive direction, and the needles run in the reverse direction when the needles are raised in the reverse direction. That is to say, when the needles are raised in the positive direction, please refer to Figure 5 The running trajectory of the knitting needle stitch is: the stitch first rises along the inclined surface of the positive needle raising triangle 88, and when it reaches the highest point (i.e., the needle raising height control triangle 85), it descends along the triangle track, and after descending to the position of the positive density triangle 84, it continues to descend along the inclined surface of the positive density triangle 84 until it passes through the bottom of the positive density triangle 84. After that, the stitch rises along the inclined surface of the elastic needle raising triangle 87, and after reaching the highest point, it descends along the inclined surface of the elastic density triangle 83 and passes through the bottom of the elastic density triangle 83 to complete a knitting row in which the yarn is woven into the positive needle first and then the elastic is woven into the elastic.

[0083] When starting the needle in reverse, please refer to Figure 6 The running trajectory of the knitting needle stitch is: the stitch rises along the inclined surface of the reverse needle raising triangle 89, and when it reaches the highest point (i.e., the needle raising height control triangle 85), it descends along the triangle track, and when it descends to the position of the reverse density triangle 86, it continues to descend along the inclined surface of the reverse density triangle 86 until it passes the bottom of the reverse density triangle 86, so as to complete a reverse needle raising knitting row in which only yarn is woven in but no elastic band is woven in.

[0084] The specific structural design of the above-mentioned yarn guide needle structure and elastic guide needle structure is only a preferred implementation method after determining their functions and relative positions, so as to achieve the purpose of not causing the elastic thread to break during the reverse needle raising process. In actual processing and production, some detailed adjustments can also be made.

[0085] For a clearer understanding of the weaving method of the bidirectional spiral weave, please refer to Figure 7 , Figure 7 The schematic diagram in the figure is a simple schematic diagram of the first knitting thread of the forward knitting and the second knitting thread of the reverse knitting spiraling with each other. The knitting density is controlled by controlling the lifting amplitude of the knitting needle to achieve the effect of efficient knitting.

[0086] In addition, the forward needle raising cam 88 is located on the right side of the reverse needle raising cam 89, and the guide angles of the forward needle raising cam 88 and the reverse needle raising cam 89 are consistent in inclination.

[0087] Then, the yarn guide needle structure also includes a half needle triangle 810, which is located above the middle position of the forward needle raising triangle 88 and the reverse needle raising triangle 89, and the needle raising height control triangle 85 is located above the half needle triangle 810.

[0088] In addition, the needle guide assembly further includes a needle pressing triangle 82 , and the needle pressing triangle 82 is located on the left side of the elastic density triangle 83 .

[0089] In this embodiment, a flat needle cam 811 is provided above the needle pressing cam 82, and the flat needle cam 811 is fixedly mounted on the mounting plate.

[0090] Here, the designs of the needle pressing triangle 82 and the flat needle triangle 811 are both for cooperating to complete a more stable needle guiding work for the knitting needles. Since it is the existing technology, it will not be elaborated here.

[0091] More specifically, a clearance groove 701 is provided on one side of the needle guide head 7 , and one side of a portion of the needle guide assembly extends through the mounting plate 81 and is built into the clearance groove 701 .

[0092] The core inventive idea of ​​this application is: if there are two fluctuations in a motion trajectory, with the small fluctuation in front and the large fluctuation in the back, then the large fluctuation will affect the desired result of the small fluctuation; but we do the opposite and put the large fluctuation in front and the small fluctuation in the back, so that the large fluctuation does not affect the result of the small fluctuation, and the small fluctuation cannot interfere with the completed large fluctuation, and ultimately the desired result is achieved.

[0093] The above description of a guide triangle device suitable for bidirectional knitting of the rib part of a glove of the present invention is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
