Description

Technical Field

[0001] The present invention relates to the technical field of flat knitting machines, in particular to a head assembly of a flat knitting machine. Background Art

[0002] The knitting process of an electric flat knitting machine is generally as follows: the cam mechanism is moved to force the knitting needle to perform regular lifting and lowering movements in the needle groove of the needle plate, and the yarn can be woven into a knitted fabric through the action of the needle hook and the needle tongue. During the rising process of the knitting needle, the coil gradually exits the needle hook. When knitting gloves, the existing electric flat knitting machine requires the cooperation of two cam mechanisms. Specifically, when the needle guide head moves from left to right, the needle raising cam of the needle guide cam bottom plate in 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 raising cam of the needle guide cam bottom plate in the front needle guide head pushes up the knitting needle on the front needle bed and takes over the yarn in the same yarn mouth to complete another knitting action; the needle guide head completes a reciprocating action from left to right and then back to left, which is called completing a horizontal row of needles. This cycle is repeated, and the yarn is woven in a spiral manner.

[0003] However, the machine head in the existing flat knitting machine for gloves cannot perform bidirectional knitting, so the glove processing efficiency is very low. Therefore, a flat knitting machine machine head assembly is proposed. Summary of the Invention

[0070] like Figure 1-13 , an embodiment of the present invention provides a flat knitting machine head assembly, such as Figure 1 As shown, it includes a first needle guide head 1 and a second needle guide head 2 that are arranged opposite to each other. The first needle guide head 1 and the second needle guide head 2 are used to knit the first side and the second side of the glove respectively, and can perform reciprocating knitting motion in the same direction along the left and right directions, knitting the first side and the second side of the glove at the same time and in the same direction.

[0071] like Figure 2-4As shown, the first needle guide head 1 includes a first triangular base plate 11 and a first left density cam 12, a first left needle-raising cam 13, a first middle cam 14, a first knitting needle cam 15, a first right needle-raising cam 16 and a first right density cam 17 installed on the first triangular base plate 11. The first left density cam 12 and the first left needle-raising cam 13 are arranged at intervals, the first right needle-raising cam 16 and the first right density cam 17 are arranged at intervals, the first knitting needle cam 15 and the first middle cam 14 are arranged at intervals, the first middle cam 14 and the first knitting needle cam 15 are located in the middle, wherein the first middle cam 14 is also known as the Zhongshan cam, which acts as a thimble, and the first knitting needle cam 15 is also known as the herringbone. The triangle is used to limit the highest position of the knitting needle and guide the knitting needle. Specifically, the first left density triangle 12, the first left needle-raising triangle 13, the first middle triangle 14, the first knitting triangle 15, the first right needle-raising triangle 16 and the first right density triangle 17 form a first needle guide channel. According to the arrangement of the first left needle-raising triangle 13, the first middle triangle 14 and the first right needle-raising triangle 16, there are various path shapes of the first needle guide channel, including a bidirectional needle guide channel, a unidirectional needle guide channel and a tuck needle guide channel, so that the first needle guide head 1 can perform bidirectional knitting, unidirectional knitting and tuck knitting of the first side, which can speed up the knitting speed of the first side of the glove. Figure 11-13As shown, the second needle guide head 2 includes a second triangular base plate 21 and a second left density triangle 22, a second left needle triangle 23, a second middle triangle 24, a second knitting needle triangle 25, a second right needle triangle 26 and a second right density triangle 27 installed on the second triangular base plate 21. The second left density triangle 22 and the second left needle triangle 23 are arranged at intervals, the second right needle triangle 26 and the second right density triangle 27 are arranged at intervals, the second knitting needle triangle 25 and the second middle triangle 24 are arranged at intervals, the second middle triangle 24 and the second knitting needle triangle 25 are located in the middle, wherein the second middle triangle 24 is also known as Zhongshan triangle, which acts as a thimble, and the second knitting needle triangle 25 is also known as the herringbone. The triangle is used to limit the highest position of the knitting needles and guide the knitting needles. Specifically, the second left density triangle 22, the second left needle starting triangle 23, the second middle triangle 24, the second knitting needle triangle 25, the second right needle starting triangle 26 and the second right density triangle 27 form a second needle guide channel. The path shape of the second needle guide channel formed according to the setting of the second left needle starting triangle 23, the second middle triangle 24 and the second right needle starting triangle 26 is various, including a bidirectional needle guide channel, a unidirectional needle guide channel and a tuck needle guide channel, so that the first needle guide head 1 can perform bidirectional weaving, unidirectional weaving and tuck weaving of the first side, which can speed up the weaving speed of the second side of the glove. In summary, the first needle guide head 1 and the second needle guide head 2 can knit the first side and the second side of the glove at the same time and in the same direction, and each needle guide head can perform bidirectional weaving, tuck weaving and unidirectional weaving, which greatly speeds up the weaving speed of the gloves. Compared with unidirectional weaving, the weaving speed is at least doubled. Moreover, in the actual installation process, such as Figure 1 As shown, for example, the first needle guide head 1 is used as the front head, the second needle guide head 2 is used as the rear head, and the front head and the rear head are arranged relative to each other, then the positions of the first left needle-raising triangle 13 and the first left density triangle 12 correspond to the positions of the second right needle-raising triangle 26 and the second right density triangle 27 respectively, the positions of the first middle triangle 14 and the first knitting needle triangle 15 correspond to the positions of the second middle triangle 24 and the second knitting needle triangle 25 respectively, and the positions of the first right needle-raising triangle 16 and the first right density triangle 17 correspond to the positions of the second left needle-raising triangle 23 and the second left density triangle 22 respectively.

[0072] Preferably, the first left needle triangle 13 and the first right needle triangle 16 can both independently telescopically move along the thickness direction of the first triangle base plate 11, the first left needle triangle 13 is driven to move by an external driving mechanism, and the first right needle triangle 16 can move by an external force, the first left needle triangle 13 has a full height position and a flush position, the first right needle triangle 16 has a full height position and a flush position, wherein the full height position is that the first left needle triangle 13 completely protrudes from the first triangle base plate 11, so that the high needle and the low needle are all woven along the edge of the first left needle triangle 13 and are guided by the first left density triangle 12, and the flush position is that the first left needle triangle 13 falls to a position flush with the first triangle base plate 11, but due to the installation fit , the error in parts manufacturing can allow the first left needle triangle 13 to be slightly higher than the first triangle bottom plate 11, up to 5% higher than the first left needle triangle 13; wherein, when the first left needle triangle 13 is in full height, at the same time, the first left density triangle 12, the first middle triangle 14, the first knitting needle triangle 15, the first right needle triangle 16 and the first right density triangle 17 are also in full height, the first left density triangle 12, the first left needle triangle 13, the first middle triangle 14, the first knitting needle triangle 15, the first right needle triangle 16 and the first right density triangle 17 form a two-way needle guide channel, the knitting needles are weaved from left to right and from right to left relative to the first needle guide mechanism, that is, bidirectional weaving, such as Figure 2 As shown; when the first left needle-raising triangle 13 is in the flush position, the first left density triangle 12, the first left needle-raising triangle 13, the first middle triangle 14, the first knitting needle triangle 15, the first right needle-raising triangle 16 and the first right density triangle 17 form a one-way needle guide channel. As shown in the figure, the knitting needle moves from right to left along the two-way needle guide channel relative to the first needle guide head 1, and then in the process of moving from left to right, the knitting needle can directly move to the right from the top of the first left needle-raising triangle 13, and then the knitting needle will squeeze the second left needle-raising triangle 23, so that the second left needle-raising triangle 23 drops to be flush with the first triangle bottom plate 11, so that the knitting needle can weave in the process of moving from right to left relative to the first needle guide head 1, and then the knitting needle does not weave in the process of moving from right to left relative to the first needle guide head 1, that is, unidirectional knitting, as shown Figure 3 As shown, the first needle guide head 1 can weave in both bidirectional and unidirectional directions.

[0073] When the second left-starting cam 23 is in its full-height position, the second left density cam 22, the second middle cam 24, the second knitting needle cam 25, the second right-starting cam 26 and the second right density cam 27 are also in their full-height positions. The second left density cam 22, the second left-starting cam 23, the second middle cam 24, the second knitting needle cam 25, the second right-starting cam 26 and the second right density cam 27 form a two-way needle guide channel, and the knitting needles are weaved from left to right and from right to left relative to the second needle guide mechanism. Figure 11 As shown; when the second left needle-raising triangle 23 is in the flush position, the second left density triangle 22, the second left needle-raising triangle 23, the second middle triangle 24, the second knitting needle triangle 25, the second right needle-raising triangle 26 and the second right density triangle 27 constitute a one-way needle guide channel, and the knitting needle moves from right to left along the one-way needle guide channel relative to the second needle guide head 2, and then the knitting needle can move directly to the right from the second left needle-raising triangle 23, and then the knitting needle will squeeze the second left needle-raising triangle 23, so that the second left needle-raising triangle 23 drops to be flush with the second triangle bottom plate 21, so that the knitting needle can weave in the process of moving from right to left relative to the second needle guide head 2, and then the knitting needle does not weave in the process of moving from right to left relative to the second needle guide head 2, that is, unidirectional knitting, as shown Figure 12 As shown, the second needle guide head 2 can weave in both bidirectional and unidirectional directions.

[0074] Preferably, the first left needle-raising triangle 13 and the first right needle-raising triangle 16 are both provided with a first transition inclined surface on the side close to each other; thus, after the knitting needle moves to the right from the top of the first left needle-raising triangle 13, it can slowly move to the upper end surface of the first right needle-raising triangle 16 through the first transition inclined surface, thereby stably squeezing the first right needle-raising triangle 16, so that the first right needle-raising triangle 16 can stably move to a position flush with the first triangle bottom plate 11, and the knitting needle can pass stably without getting stuck; the second left needle-raising triangle 23 and the second right needle-raising triangle 26 are both provided with a second transition inclined surface on the side close to each other, so that after the knitting needle moves to the right from the second left needle-raising triangle 23, it can slowly move to the upper end surface of the second right needle-raising triangle 26 through the second transition inclined surface, thereby stably squeezing the second right needle-raising triangle 26, so that the second right needle-raising triangle 26 can stably move to a position flush with the second triangle bottom plate 21, and the knitting needle can pass stably without getting stuck. In summary, the first needle guide head 1 can weave in both directions by controlling the first left needle triangle 13, and the second needle guide head 2 can weave in both directions by controlling the second left needle triangle 23, which is more convenient to use. Figure 5-6 As shown, the first needle guide head 1 also includes a first pushing assembly 18, wherein the first pushing assembly 18 is arranged on the back of the first triangular bottom plate 11, and the first pushing assembly 18 is driven by an external force to enable the first left needle triangle 13 to switch between the full height position and the flush position; specifically, the first pushing assembly 18 includes a first rotating member 181 and a first driving rod, one end of the first driving rod is rotatably connected to the first rotating member 181, and the other end of the first driving rod is provided with a first lifting surface 184, and a first movable rod 185 that passes through the first triangular bottom plate 11 is provided on the back of the first left needle triangle 13, and the first movable rod 185 is provided with a first protruding rod 186, and the first lifting surface 18 The first cam 13 for starting the left needle is moved from the full height position to the flush position by cooperating with the first protruding rod 186, wherein the first rotating member 181 is used to cooperate with the external driving force. By lifting the first rotating member 181, the lifting and lowering of the first rotating member 181 will drive the first driving rod to rotate, and the rotation of the first driving rod will drive the first lifting surface 184 to move below the first cam 186, and then slowly lift the first cam 186 until the first cam 186 contacts the highest end of the first lifting surface 184, so that the first cam 13 for starting the left needle is connected to the first cam 186 and will descend, and finally move to the flush position; wherein the first rotating member 181 can be a bearing or a rotating wheel.

[0075] Correspondingly, in order to realize the reset of the first left needle starting triangle 13, that is, to move from the flush position to the full height position, the first needle guide head 1 also includes a first reset spring 187 and a second reset spring.

Specifically, a first mounting plate is provided on the back side of the first triangle bottom plate 11, and the first mounting plate is regarded as a part of the first triangle bottom plate 11. The end of the movable rod 185 away from the back of the first cam base 11 passes through the first mounting plate, and the second return spring is sleeved on the first movable rod 185 between the first left needle cam 13 and the first mounting plate. When the external force is removed, the first return spring 187 will return to its normal state from the stretched state, pulling the first driving rod to rotate in the opposite direction, so that the first lifting surface 184 moves from the bottom of the first protruding rod 186 to the outside, and the first left needle cam 13 will return to its full height position under the action of the second return spring. After the above process, the first left needle cam 13 will complete the transformation of the working position from the full height position to the flush position and then to the full height position, which has a simple structure and is easy to use. The back of the first right needle cam 16 has a sliding rod, and the end of the sliding rod away from the first right needle cam 16 passes through the first mounting plate. The sliding rod sleeve between the first mounting plate and the back of the first right needle cam 16 is provided with a spring, which is used to reset the first right needle cam 16, that is, to raise the flush position to the full height position.

[0077] Specifically, the first middle cam 14 performs independent telescopic movement along the thickness direction of the first triangular base plate 11, and the first middle cam 14 has a half-height position and a full-height position, wherein the half-height position means that the first middle cam 14 protrudes from the height of the first triangular base plate 11, so that the high needle still moves along the edge of the first middle cam 14 and is guided by the first knitting needle cam 15, and the low needle crosses the first middle cam 14 from the surface of the first middle cam 14. The height of the half-height position of the first middle cam 14 can be 35%-65% of the height of the full-height position. For example, when the height of the full-height position is 4±0.5mm, the height of the half-height position can be 2±0.5mm; the first needle guide head 1 also includes a second pushing assembly 19, which is arranged on the back of the first triangular base plate 11. The second pushing assembly 19 is driven by an external force to enable the first middle cam 14 to switch from the full-height position to the half-height position, and then from the half-height position to the full-height position.

[0079] In order to reset the first middle triangle 14, that is, to move it from the half needle position to the full height position, the first needle guide head 1 also includes a third return spring 195 and a fourth return spring. The third return spring 195 is arranged between the back of the first triangular base plate 11 and the second push assembly 19, and is used to reset the second push assembly 19 after the external driving force is withdrawn; the fourth return spring is arranged between the first middle triangle 14 and the first triangular base plate 11, and has the tendency to make the first middle triangle 14 have a reset from the half needle position to the full height position. Specifically, the end of the second movable rod 193 away from the back of the second triangular base plate 21 passes through the first mounting plate, and the fourth return spring is sleeved on the second movable rod 193 between the first middle triangle 14 and the first mounting plate; when the external driving force is withdrawn, the third return spring 195 will return to the normal state from the stretched state, and will pull the second drive rod 192 to rotate in the opposite direction, so that the end of the second drive rod 192 close to the second protruding rod 194 moves to the outside or moves into the first groove 1926, thereby returning to the initial full height position under the action of the fourth return spring.

[0080] The flat knitting machine head assembly also includes a first drive assembly 3, the driving end of the first drive assembly 3 is connected to the first push assembly 18 and the second push assembly 19, driving the first push assembly 18 and the second push assembly 19 to work simultaneously, and the first drive assembly 3 has a first rest position 33, a first drive position 34 and a second drive position 35; specifically, as Figure 8 As shown, when the first driving assembly 3 has not moved to the second driving position 35, the first pushing assembly 18 and the second pushing assembly 19 are schematically shown, the first inclined surface 1921 is separated from or just in contact with the second protruding rod 194, and the first lifting surface 184 is not in contact with the first protruding rod 186, so that the first left-starting cam 13 and the first middle cam 14 are both in full height positions, which can form a full-mesh needle guide channel for bidirectional knitting; Figure 9As shown, when the first drive assembly 3 is in the second drive position 35, the second pushing assembly 19 is lifted and the first middle cam 14 is moved to a half-high position, and the first pushing assembly 18 is pushed at the same time. The first left needle-raising cam 13 is still in the full-high position. At this time, the first left density cam 12, the first left needle-raising cam 13, the first middle cam 14, the first knitting needle cam 15, the first right needle-raising cam 16 and the first right density cam 17 form a tuck needle guide channel for tuck knitting, that is, the first drive assembly 3 moves to the second drive position 3 5, its driving end will lift the second driving rod 192 to rotate, the end of the second driving rod 192 will rotate, the second protruding rod 194 will first contact the lowest end of the first inclined surface 1921, and then the second driving rod 192 will continue to rotate, the second protruding rod 194 will move to the first boss 1925, and then contact the first boss 1925, the first middle triangle 14 will move from the full height position to the half height position, and at this time the end of the first driving rod will rotate, the first lifting surface 184 will move to the position of the first protruding rod 186; Figure 10 As shown, when the first drive assembly 3 is in the first drive position 34, the second pushing assembly 19 is lifted and the first middle cam 14 is moved from a half-high position to a full-high position. At the same time, the first pushing assembly 18 is pushed, and the first left needle-raising cam 13 is moved from a full-high position to a half-high position. At this time, the first left density cam 12, the first left needle-raising cam 13, the first middle cam 14, the first knitting needle cam 15, the first right needle-raising cam 16 and the first right density cam 17 form a one-way needle guide channel for one-way knitting or glove finger seam (sealing) action, that is, the first drive assembly 3 is moved from the second drive position 3 During the movement to the first driving position 34, the driving end thereof will lift the second driving rod 192 and continue to rotate. The end of the second driving rod 192 will rotate, and the second protruding rod 194 will first move relatively from the surface of the first boss 1925 to the lowest end of the second inclined surface 1922, and the first middle cam 14 will move from the half-height position to the full-height position. At this time, the end of the first driving rod will rotate, and the first lifting surface 184 will move below the first protruding rod 186 until the first protruding rod 186 contacts the highest point of the first lifting surface 184, thereby the first left-starting needle cam 13 moves from the full-height position to the flush position. For example, in this embodiment, when the first drive component 3 is in the starting position, that is, the first inclined surface 1921 is located at the second protruding rod 194 and does not contact, when the first drive component 3 moves from the starting position to the second drive position 35, the driving end of the first drive component 3 is lifted to 2 mm, the first middle triangle 14 moves from the full high position to the half high position, and the left needle triangle is still at the full high position. At this time, the left and right low needle tuck knitting can be achieved. When the first drive component 3 moves from the second drive position 35 to the first drive position 34, the driving end of the first drive component 3 is lifted to 5 mm, the first middle triangle 14 moves from the half high position to the full high position, and the left needle triangle is in the flush position, which can achieve one-way knitting or glove finger seam (sealing) action.

[0081] Specifically, the first driving assembly 3 includes a first motor, a first push rod 31 and a first cam 32. The first motor drives the first cam 32 to rotate, so that the first push rod 31 has a first rest position 33, a first driving position 34 and a second driving position 35. The first cam 32 is connected to the first output shaft of the first motor. The first cam 32 is provided with a first curved groove that enables the first push rod 31 to reach the first rest position 33 and the first driving position 34; the first push rod 31 is provided with a first inclined groove 321 and a first protrusion 322. The first output shaft passes through the first inclined groove 321 and the first protrusion 322 is placed in the first curved groove. The rotation of the first motor causes the first protrusion 322 to move along the first curved groove to change the relative position of the first protrusion 322 and the first output shaft, driving the first push rod 31 to move between the first rest position 33 and the first driving position 34. The first needle raising triangle has a full height position and a flush position.

[0082] Correspondingly, the first curved groove includes a first curved segment 323, a second curved segment 324, a third curved segment 325, a fourth curved segment 326 and a fifth curved segment 327 which are connected in sequence from the starting end to the end. The starting end of the first curved segment 323 is the starting end of the first curved groove, and the distance from the starting end to the end to the center A of the first cam 32 is La1, which corresponds to the first rest position 33 of the first push rod 31; the second curved segment 324 is smoothly connected between the first curved segment 323 and the third curved segment 325, and the distance between the second curved segment 324 and the center A of the first cam 32 gradually increases from the connection end with the first curved segment 323 to the connection end with the third curved segment 325, with the minimum distance being La1 and the maximum distance being La2. The distance between the third curved segment 325 and the center A of the first cam 32 from the starting end to the end is La2, which corresponds to the second driving position 35 of the first push rod 31; the fourth curved segment 326 is smoothly connected between the third curved segment 325 and the fifth curved segment The distance between the curved segments 327 and the center A of the first cam 32 gradually increases from the connection end with the third curved segment 325 to the connection end with the fifth curved segment 327, with the minimum distance being La2 and the maximum distance being La3. The end of the fifth curved segment 327 is the end of the first curved groove, and from the connection end with the fourth curved segment 326 to the end, the distance between the fifth curved segment 327 and the center A of the first cam 32 is La3, corresponding to the first driving position 34 of the first push rod 31, and satisfying the following relationship: La1<La2<La3. Therefore, the height of the first driving position 34 is higher than the height of the second driving position 35. When the first push rod 31 is in the first driving position 34, the height of the first rotating member 181 is higher than the height when the first push rod 31 is in the second driving position 35. When the first push rod 31 is in the first driving position 34, the height of the second rotating member 191 is higher than the height when the first push rod 31 is in the second driving position 35. Therefore, as shown in the attached figure Figure 8As shown, when the first protrusion 322 is in the first curved section 323 and the first push rod 31 is in the first rest position 33, it contacts the first rotating member 181 and separates the first protruding rod 186 from the first lifting surface 184, and the second protruding rod 194 is separated from the first inclined surface 1921 or is tangent to the first inclined surface 1921. The first left-starting needle triangle 13 is at full height, and the first middle triangle 14 is at full height; as shown in the attached figure Figure 9 As shown, when the first protrusion 322 is in the third curved section 325 and the first push rod 31 is in the second driving position 35, the first rotating member 181 is lifted, so that the first protrusion 186 is tangent to or separated from the first lifting surface 184, the second protrusion 194 is located on the first boss 1925, the first left-starting needle triangle 13 is in full height, and the first middle triangle 14 is in half height; as shown in the attached Figure 10 As shown, the first protrusion 322 is in the fifth curved segment 327, and when the first push rod 31 is located at the first driving position 34, the first rotating member 181 is lifted, the first protrusion 186 is located at the highest point of the first lifting surface 184, the second protrusion 194 is located in the first groove 1926, the first left-starting needle triangle 13 is in the flush position, and the first middle triangle 14 is in the full height position.

[0083] Specifically, the second needle guide head 2 also includes a third pushing assembly, which is arranged on the back of the second triangular base plate 21. The structure and driving principle of the third pushing assembly are the same as those of the first pushing assembly 18. Specifically, the third pushing assembly can, under external driving force, enable the second left needle starting triangle 23 to switch from the full height position to the flush position; specifically, the first pushing assembly 18 and the third pushing assembly have the same structure, the third pushing assembly includes a third rotating member and a third driving rod, the third driving rod is rotatably arranged on the second triangular base plate 21, one end of the third driving rod is rotatably connected to the third rotating member, and the other end of the third driving rod is provided with a second lifting surface, and a third movable rod is provided on the back of the second left needle starting triangle 23, which passes through the second triangular base plate 21, and a third protruding rod is provided on the back of the second left needle starting triangle 23. The second lifting surface cooperates with the third protruding rod to make the second left needle starting triangle 23 move from the full height position to the flush position. The specific driving principle will not be repeated here, and reference will be made to the driving process of the first pushing assembly 18.

[0084] Correspondingly, in order to realize the reset of the second left needle cam 23, that is, to move from the flush position to the full height position, the second needle guide head 2 also includes a fifth reset spring and a sixth reset spring. The fifth reset spring is arranged between the back side of the second triangular bottom plate 21 and the third pushing assembly, and is used to reset the third pushing assembly after the external driving force is withdrawn; the sixth reset spring is arranged between the second left needle cam 23 and the second triangular bottom plate 21, and has the tendency to reset the second left needle cam 23 from the flush position to the full height position. Specifically, a second mounting plate is provided on the back side of the second triangular bottom plate 21, and the second mounting plate is regarded as a part of the second triangular bottom plate 21. The end of the third movable rod away from the back of the second triangle base plate 21 passes through the second mounting plate, and the sixth return spring is sleeved on the third movable rod between the second left needle triangle 23 and the first mounting plate. After the external force is removed, the fifth return spring will return to the normal state from the stretched state, and will pull the third drive rod to rotate in the opposite direction, so that the second lifting surface moves from the bottom of the third protruding rod to the outside, and the second left needle triangle 23 will be restored to the full height position under the action of the sixth return spring; after the above process, the second left needle triangle 23 will complete the transformation of the working position from the full height position to the flush position and then to the full height position. It has a simple structure and is easy to use.

[0085] Specifically, the second middle triangle 24 performs independent telescopic movement along the thickness direction of the second triangular bottom plate 21. The second middle triangle 24 has a half-height position and a full-height position. The definitions of the half-height position and the full-height position are the same as those of the half-height position and the full-height position of the first middle triangle 14. The second needle guide head 2 also includes a fourth pushing assembly, which is arranged on the back of the second triangular bottom plate 21. The fourth pushing assembly is driven by an external force to enable the second middle triangle 24 to switch from the full-height position to the half-height position, and then from the half-height position to the full-height position. The fourth pushing assembly and the second pushing assembly 19 The structure and working principle are the same as those of the fourth pushing assembly, which includes a fourth rotating member and a fourth driving rod.
