Description

Technical Field

[0001] The utility model relates to a bottom plate structure of a computerized flat knitting machine, in particular to a bottom plate structure matched with a sinking needle plate. Background Art

[0002] The computerized flat knitting machine is a double needle plate latch needle weft knitting machine. Its cam device is like a set of flat cams. The pins of the knitting needles can enter the grooves of the cams. The moving cam forces the knitting needles to perform regular lifting and lowering movements in the needle grooves of the needle plate. Through the actions of the needle hook and the needle latch, the yarn can be woven into a knitted fabric. The needle transport speed of existing computerized flat knitting machines is constantly increasing. During operation, the heels of the knitting needles are very likely to collide with the control cam, resulting in obstruction of the operation of the computerized flat knitting machine. For this reason, computerized flat knitting machines have also been updated and upgraded, and a sinking needle knitting needle structure that enables the knitting needles to sink into the needle grooves has been developed. However, the existing bottom plate structure can no longer cooperate with the needle plate with the sinking needle capability to perform the corresponding sinking needle work, so it is necessary to improve and optimize the existing bottom plate structure.

[0071] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0072] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0073] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0074] like Figures 1 to 6 The bottom plate structure of a needle plate with a sinking needle plate shown in the figure includes a bottom plate 1 installed in the head of a computer flat knitting machine, and at least one group of weaving units 2 are installed on the control board to control the knitting needles on the needle bed of the computer flat knitting machine to complete the interdependent weaving actions. It should be noted that in this embodiment, the weaving unit is specifically divided into a knitting needle control mechanism 21, a needle push control mechanism 22 and a needle selection control mechanism 23. Among them, the knitting needle control mechanism forms a needle transport channel that guides the running trajectory of the knitting needle by lifting and lowering on the bottom plate; the needle push control mechanism forms a needle push channel that guides the running trajectory of the needle pusher by lifting and lowering on the bottom plate according to the implementation state of the needle pusher; as for the needle selection control mechanism, it forms a needle selection channel that guides the running of the needle selection plate by stretching and retracting on the bottom plate.

[0075] It should be noted that in this solution, a corresponding control unit 3 is also provided on the back of the base plate for the lifting and lowering of the knitting needle control mechanism, the needle push control mechanism and the needle selection control mechanism in the adapted driving knitting unit. Specifically, the control unit is divided into a first control mechanism 31 and a second control mechanism 32 according to the degree of integration. The first control mechanism is drivingly connected to the knitting needle control mechanism 21 and the needle selection control machine 22 to control the lifting and lowering of the two on the base plate. The second control mechanism 32 is drivingly connected to the needle selection control mechanism to control the corresponding action of the needle selection mechanism.

[0076] It should be noted that, in the present embodiment, if the knitting needle enters the needle transport groove in the ordinary manner, the butt of the knitting needle will always be exposed outside the needle groove. At this time, with the reciprocating motion of the machine head, other auxiliary triangles on the base plate 1 and even the triangles in the knitting needle control mechanism are at risk of colliding with the exposed butt of the knitting needle, thereby affecting the normal operation of the computer flat knitting machine.

[0077] To this end, the present invention provides a triangular boss 4 at the entry and exit ends of the needle transport groove that guides the running trajectory of the needle heel. The inclined surface of the boss is smoothly connected to the surface of the bottom plate, so that when the needle heel enters and exits the needle transport groove, it can be retracted into the needle groove due to the top pressure from the boss.

[0078] It should be noted that, in the embodiment, the first control mechanism 31 simultaneously controls the lifting and lowering coordination of the knitting needle control mechanism 21 and the needle push control mechanism 22. Among them, the part that controls the lifting and lowering of the knitting needle control mechanism is the cam assembly 3101. Specifically, the connection relationship between the cam assembly and the knitting needle control mechanism is as follows: Figure 5 , Figure 6 As shown. The knitting needle control mechanism includes a needle transfer cam A2101, which is in a herringbone structure and is plugged into the bottom plate 1 in a sliding manner. Figure 1 As shown, the needle transfer cam A is arranged below the needle transfer cam to guide the running track of the needle butt by lifting and lowering.

[0079] The cam assembly is as Figure 6 As shown, it includes a motor A3102 fixed on the back of the base plate 1, and the motor A is horizontally arranged and is a double output shaft motor. A cam 3103 is connected to one of the output shafts of the motor A. At the same time, a cam control seat 3104 is also fixedly installed on the back of the base plate, and a guide rod A3105 is inserted in the cam control seat in a sliding fit. It needs to be said that one end of the guide rod A is fixedly connected to the needle turning triangle A slidably inserted in the base plate, and the other end passes through the rear cam control seat, and the end face is smoothly abutted on the guide wheel rim of the cam. It needs to be explained that in this scheme, a spring 3106 is also sleeved on the guide rod A, and the spring is in a stretched state, so that when the distance from the cam wheel rim in contact with the end of the guide rod A to the axis of the motor output shaft is reduced, the needle turning triangle A can be retracted into the base plate under the action of the spring.

[0080] In addition, in this embodiment, Figure 5 , Figure 6 As shown, the first control mechanism also includes a guide mechanism 3107 which is drivingly connected to the push-pin control mechanism 22 to drive the push-pin control mechanism to extend and retract.

[0081] Specifically, in this embodiment, the needle pushing control mechanism includes a set of knitting cam components 2201 and a set of needle receiving cam components 2214. Figure 1 As shown, the needle receiving cam assembly is located below the knitting cam assembly, and a track channel for guiding the needle pusher butt to run is formed between the two. Figure 1 As shown, the knitting cam assembly 2201 includes knitting cams A1 2202 and A2 2203 symmetrically arranged on the left and right sides, which are arranged in an eight-shaped pattern on the bottom plate and are slidably inserted into the bottom plate. The needle receiving cam assembly includes needle receiving cam A1 2215 fixed on the bottom plate, and needle receiving cams A2 and A3 symmetrically distributed on the left and right sides of needle receiving cam A1 and slidably inserted into the bottom plate. It should be noted that the needle receiving cam A1, needle receiving cam A2 and needle receiving cam A3 fit each other and are in a Y shape.

[0082] As a guide mechanism for controlling the movement of the push needle control mechanism, a triangle control seat 3112 is fixedly installed on the bottom plate 1 by bolts, and a plurality of sockets are provided on the triangle control seat, and four guide rods B3111 are inserted into the sockets in a sliding manner. It should be noted that the four guide rods B are fixedly connected to the corresponding knitting cam A1, knitting cam A2 and needle receiving cam A2, needle receiving cam A3 respectively.

[0083] like Figure 6 As shown, a control board A3109 and a control board B3110 are symmetrically arranged on the front and rear sides of the triangular control seat 3112. It should be noted that the control board A and the control board B are slidably mounted in the slide grooves opened on both sides of the triangular control seat so that they can slide back and forth horizontally in the slide grooves after being driven. Preferably, the outsides of the control board A and the control board B can also be locked by a pressing plate fixed on the triangular control seat. In addition, in order to realize the driving of the control board A and the control board B and save the space occupied by the power source, the guide mechanism shares the motor A in the cam assembly. Specifically, two guide gears 3108 are also installed on the output shaft at one end of the motor A where the cam is not installed. At the same time, a number of tooth grooves are opened on the upper edges of the control board A and the control board B. Through these tooth grooves, the control board A and the control board B are respectively meshed with the corresponding guide gears. When the motor rotates forward and backward, the control board A and the control board B can be driven to slide back and forth in the horizontal direction. It should also be noted that guide grooves are provided on both the control board A and the control board B. Specifically, the guide groove on the control board A is in the shape of an inverted "J" and the guide groove on the control board B is in the shape of a "J" so that the guide rod B3111 passing through the side of the triangle control seat and inserted into the corresponding guide groove can drive the triangle connected thereto to rise and fall on the bottom plate under the guidance of the guide groove.

[0084] like Figure 5 , Figure 6 As shown, in this embodiment, the needle selection control mechanism 23 includes a needle lifting block 2304 installed on the bottom plate and a needle selection triangle A2301 and a needle selection triangle B2302 respectively inserted into the bottom plate 1. Among them, the needle selection control mechanism is independently controlled by a second control mechanism 32 arranged on the back of the bottom plate. Specifically, the second control mechanism 32 includes a needle selection triangle seat 3201 fixedly installed on the back of the bottom plate by bolts, and two guide rods C are inserted into the needle selection triangle seat. It should be noted that the lower end of the guide rod C is fixedly connected to the corresponding needle selection triangle A or needle selection triangle B. At the same time, a hole is opened on the side of the needle selection triangle seat so that the protruding part set on the guide rod C3207 can extend to the outside of the needle selection triangle seat. In addition, a needle selection control plate 3204 that can slide horizontally is also installed on the side of the needle selection triangle. Two Z-shaped guide grooves A are opened on the needle selection control plate in a left-right symmetrical manner, and the protruding part on the guide rod C can be inserted into the guide groove A. At this time, the guide rod C can rise and fall synchronously on the bottom plate following the ups and downs of the guide groove A. Figure 2 As shown, in order to drive the reciprocating sliding of the needle selection control board, a motor B3202 is fixedly installed on the bottom plate 1, and a swing rod 3203 is connected to the output shaft of the motor B. At the same time, a swing groove 3205 is vertically opened on the needle selection control board, and one end of the swing rod slides into the swing groove. When the motor B rotates, the needle selection control board swings left and right under the action of the swing rod, and reciprocating sliding in the horizontal direction is realized, thereby driving the guide rod C3207 in the guide groove A3206 to follow the rise and fall.

[0085] It should be noted that, as a preferred embodiment of the above scheme, the needle lifting block can follow the lifting and lowering. Specifically, a needle lifting seat 2305 is fixedly installed on the bottom plate 1, and the needle lifting block can be slidably inserted into the needle lifting seat for lifting and lowering. At the same time, a guide block 2304 is also provided on the needle lifting seat, and a guide groove B is provided on the needle selection control board, and the guide block is slidably inserted into the guide groove B3208. It should be noted that the guide groove B is in an inverted "X" shape to guide the needle lifting block 2303 to lift and lower when the needle selection control board slides horizontally. It should be noted that compared with the traditional needle selection control mechanism, the needle lifting block is fixed and cannot move up and down. This design can achieve the single system working without interfering with other systems, and the short running stroke can improve the weaving efficiency.

[0086] In the above embodiment, when each cam performs a corresponding knitting action, the working mode on the bottom plate is as follows:

[0087] Weaving: When the machine head moves to the left, the needle transfer cam A is driven by the cam to the state of being retracted into the bottom plate surface, the knitting cam A1 and the needle receiving cam A3, the knitting cam A2 and the needle receiving cam A2 are all driven by the corresponding control board A and the control board B to protrude to the bottom plate surface state, the needle selection cam A1 is driven by the needle selection control board to protrude from the bottom plate surface state, and the needle selection cam A2 is driven by the control board to retract to the bottom plate surface state, thereby realizing the left-moving knitting needle trajectory of the machine head.

[0088] When the machine head moves right and left, the needle transfer cam A is driven by the cam to a state of being retracted into the bottom plate surface, and the knitting cam A1 and the needle receiving cam A3, the knitting cam A2 and the needle receiving cam A2 are all driven by the corresponding control board A and the control board B to protrude to the bottom plate surface state, the needle selection cam A2 is driven by the needle selection control board to protrude from the bottom plate surface state, and the needle selection cam A1 is driven by the control board to retract to the bottom plate surface state, thereby realizing the right-moving knitting needle trajectory of the machine head.

[0089] Tuck: When the machine head moves to the left, the needle transfer cam A is controlled by the cam to the state of retracting into the bottom plate surface, the knitting cam A1 and the needle receiving cam A3 are driven by the corresponding control board A and control board B to the state of protruding from the bottom plate surface, the knitting cam A2 and the needle receiving cam A2 are driven by the corresponding control board A and control board B to the state of retracting into the bottom plate surface, and the needle selecting cam A1 and the needle selecting cam A2 are both driven by the control board to the state of retracting into the bottom plate surface, thereby realizing the needle trajectory of the machine head moving to the left.

[0090] When the machine head moves right and left, the needle transfer cam A is controlled by the cam to a state of being retracted into the bottom plate surface, the knitting cam A1 and the needle receiving cam A3 are driven by the corresponding control boards A and B to protrude from the bottom plate surface, the knitting cam A2 and the needle receiving cam A2 are driven by the corresponding control boards A and B to be retracted into the bottom plate surface, and the needle selecting cam A1 and the needle selecting cam A2 are both driven by the control board to be retracted into the bottom plate surface, thereby realizing the needle trajectory of the right movement of the machine head.

[0091] Needle transfer: when the machine head moves to the left, the needle transfer cam A is controlled by the cam to a state of protruding from the bottom plate surface, the knitting cam A1 and the needle receiving cam A3 are driven by the corresponding control board A and the control board B to a state of protruding from the bottom plate surface, the knitting cam A2 and the needle receiving cam A2 are driven by the corresponding control board A and the control board B to a state of retracting into the bottom plate surface, the needle selection cam A1 is driven by the needle selection control board to a state of protruding to the bottom plate surface, and the needle selection cam A2 is driven by the needle selection control board to a state of retracting to the bottom plate surface, thereby realizing the needle transfer trajectory of the machine head moving to the left.

[0092] When the machine head moves to the right, the needle transfer triangle A is controlled by the driving cam to the state of protruding from the bottom plate surface, the knitting triangle A1 and the needle receiving triangle A3 are driven by the corresponding control board A and the control board B to the state of retracting from the bottom plate surface, the knitting triangle A2 and the needle receiving triangle A2 are driven by the corresponding control board A and the control board B to the state of protruding from the bottom plate surface, the needle selection triangle A1 is driven by the needle selection control board to the state of retracting to the bottom plate surface, and the needle selection triangle A2 is driven by the needle selection control board to the state of protruding to the bottom plate surface, thereby realizing the needle transfer trajectory of the machine head moving to the right. Example

[0093] like Figures 7 to 13 It should be noted that the difference between this embodiment and embodiment 1 lies in the structural features of the knitting needle control mechanism 21 and the needle pushing control mechanism 22, and the structural features of the first control mechanism in the control unit for driving the knitting needle control mechanism 21 and the needle pushing control mechanism 22.

[0094] Specifically, in this solution, the knitting needle control mechanism 21 is composed of 4 needle transfer triangles slidably inserted in the bottom plate. Specifically, they are needle transfer triangle B1 2102, needle transfer triangle B2 2103, needle transfer triangle B3 2104 and needle transfer triangle B4 2105. Among them, needle transfer triangle B1 is located in the middle position, while needle transfer triangle B2 and needle transfer triangle B3 are symmetrically located on both sides of the needle transfer triangle, and needle transfer triangle B2 and needle transfer triangle B3 are in close contact with needle transfer triangle B1. The needle transfer triangle B4 is in close contact with the lower part of the needle transfer triangle B1, and is also connected with the needle transfer triangle B2 and the needle transfer triangle B3, so that the needle transfer triangle B2 and the needle transfer triangle B3 can keep synchronous lifting.

[0095] The cam assembly 3101 as the control mechanism of the knitting needle control specifically includes a motor A3102 fixedly mounted on the back of the base plate. It should be noted that in this embodiment, the motor A is installed vertically, and its output shaft is located at the bottom. A cam 3103 is installed on the output shaft of the motor A. The cam rotates horizontally under the drive of the motor A. In order to convert the horizontally rotating cam into a vertical driving ability, the guide wheel rim of the cam is distributed in a ring shape on the lower surface of the cam, and the guide wheel rim has high and low fluctuations to form a protruding presser foot surface and a concave rebound surface. At the same time, a cam control seat 3104 is installed below the motor A, and three guide rods A3105 are slidably inserted in the cam control seat. It should be noted that the lower end of the guide rod A extends out of the cam control seat and is fixedly connected to the needle turning triangle B1, the needle turning triangle B2 and the needle turning triangle B3 slidably inserted in the base plate. The upper end of the guide rod A extends out of the cam control seat and smoothly abuts on the guide wheel rim of the cam. As the cam rotates, the undulating guide wheel rim drives the guide rod A abutting on its surface to rise and fall synchronously, thereby driving the needle turning triangle B1, needle turning triangle B2 and needle turning triangle B3 connected thereto to rise and fall synchronously. It should be noted that in order to ensure that the guide rod A can always abut on the guide wheel rim of the cam, a spring 3106 is also sleeved on the guide rod A, and the spring is in a stretched state to apply a pulling force toward the cam to the guide rod A. It should be noted that in the above embodiment, in order to reduce the wear between the guide rod A and the guide wheel rim of the cam, a roller is rotatably installed on the upper end of the guide rod A to convert the sliding friction between the guide rod A and the cam into rolling friction.

[0096] In addition, if Figures 11 to 13 As shown, in this embodiment, the needle pushing control mechanism 22 specifically includes a group of knitting triangle components 2201 and a group of needle receiving triangle components 2214. Among them, the knitting triangle component 2201 is composed of a knitting triangle B1 and a knitting triangle B2 that are symmetrical on both sides, and the two are in an eight-shaped shape and are slidably inserted in the bottom plate 1. At the same time, the needle receiving triangle component 2214 is composed of a needle receiving triangle B1 and a needle receiving triangle B2 and a needle receiving triangle B3 that are symmetrically arranged on both sides of the needle receiving triangle B1, wherein the needle receiving triangle B1, the needle receiving triangle B2 and the needle receiving triangle B3 can all be lifted and slidably inserted in the bottom plate 1. In addition, as Fig.11 , Fig.12 As shown, the needle receiving triangle B1 is connected with the needle receiving triangle B2 and the needle receiving triangle B3 located on both sides thereof, so that the three needle receiving triangles form a whole that can be raised and lowered synchronously.

[0097] In addition, it should be noted that in this solution, the heel of the needle pusher needs to push the knitting cam B1, knitting cam B2, and needle receiving cam B2, B3 into the bottom plate during the movement to ensure the smooth operation of the needle pusher butt and prevent collision with the cams. In order to enable the heel of the needle pusher to slide smoothly over the above-mentioned cam surfaces, the needle-moving inclined surfaces are provided on the needle-incoming sides of the knitting cam B1, knitting cam B2, and needle receiving cam B2, B3. Specifically, as Figures 7-10 as well as Fig.13 As shown, these needle slopes are located on the movement track of the needle pusher. When the heel of the needle pusher passes, it is guided by the needle slope so that it can smoothly pass through the surfaces of the knitting triangle B1, knitting triangle B2, and the receiving triangle B2 and B3 to avoid collision with the above triangles.

[0098] It should be noted that the guide mechanism 3107 for controlling the push needle control mechanism 22 specifically includes a triangle control seat 3112 fixedly mounted on the bottom plate 1 in this solution, and a plurality of plug holes are provided on the triangle control seat, and a plurality of guide rods B3111 are inserted in the plug holes in a sliding manner, and one end of these guide rods B is respectively connected to the corresponding knitting triangle B1, knitting triangle B2, and needle receiving triangle B2, and needle receiving triangle B3. At the same time, a spring 3106 is also sleeved on the guide rod B. It should be noted that the spring is in a naturally stretched state, so that the surfaces of the knitting triangle B1, knitting triangle B2, and needle receiving triangle B2, and needle receiving triangle B3 are in an extended state when they are not subjected to pressure from the push needle heel.

[0099] Specifically, when the push needle passes through the needle receiving triangle B2, the needle receiving triangle B2 will be pressed into the retracted bottom plate surface through the inclined surface, and then enter the top tip of the needle receiving triangle B1. At this time, the needle receiving triangle B2 is not under the pressure of the needle and is ejected to the protruding bottom plate surface through the spring. The needle moves along the needle moving inclined surface on the needle receiving triangle B3, and finally when it reaches the knitting triangle B2, the knitting triangle B2 is pressed into the retracted bottom plate surface through the needle moving inclined surface. The above actions form the needle moving track of the needle receiving triangle.

[0100] It should be noted that, in this embodiment, the structures of the needle selection control mechanism and the second control mechanism are the same as those in Example 1, and therefore will not be described in detail.

[0101] like Figures 7-10 As shown, in this embodiment, when each cam performs a corresponding knitting action, the working mode on the bottom plate is as follows:

[0102] Weaving: When the machine head moves to the left, the transfer cams B1 and B3 are controlled by the cam to be retracted into the bottom plate surface, the transfer cam B2 is controlled by the cam to be protruded from the bottom plate surface, the needle selection cam A1 is driven by the needle selection control board to be protruded from the bottom plate surface, and the needle selection cam A2 is driven by the needle selection control board to be retracted from the bottom plate surface. Thus, the needle movement track of the machine head moving to the left is realized.

[0103] When the machine head moves right, the transfer cams B1 and B2 are controlled by the cam to be retracted into the bottom plate surface, the transfer cam B3 is controlled by the cam to be protruded from the bottom plate surface, the needle selection cam A1 is driven by the needle selection control board to be retracted into the bottom plate surface, and the needle selection cam A2 is driven by the needle selection control board to be protruded from the bottom plate surface. Thus, the machine head moves right to knit the needle track.

[0104] Tuck: When the machine head moves left, the cam action is the same as the needle track of the machine head moving left, the only difference is that the needle selection cam A1 and the needle selection cam A2 are driven by the needle selection control board to the retracted position on the bottom plate surface.

[0105] When the machine head moves right, the cam action is the same as the right knitting needle trajectory. The only difference is that the needle selection cam A1 and the needle selection cam A2 are both driven by the needle selection control board to the retracted bottom plate position.

[0106] Needle transfer: When the machine head moves to the left, the needle transfer cam B1, the needle transfer cam B2 and the needle transfer cam B3 are controlled by the cam to the state of protruding from the bottom plate surface, the needle selection cam A1 is driven by the needle selection control board to the state of protruding from the bottom plate surface, and the needle selection cam A2 is driven by the needle selection control board to the state of retracting from the bottom plate surface, thereby realizing the needle transfer trajectory of the machine head moving to the left.

[0107] When the machine head moves to the right, the needle transfer cam B1, the needle transfer cam B2 and the needle transfer cam B3 are controlled by the cam to the state of protruding from the bottom plate surface, the needle selection cam A1 is driven by the needle selection control board to the state of retracting from the bottom plate surface, and the needle selection cam A2 is driven by the needle selection control board to the state of protruding from the bottom plate surface, thereby realizing the needle transfer trajectory of the machine head moving to the right.

[0108] Connecting needle: The states of each cam in the connecting needle trajectory are the same as those in the transferring needle trajectory, except for the needle selecting cam A1 and the needle selecting cam A2. The left and right movements of the machine head in the connecting needle trajectory are both retracted into the bottom plate. Example

[0109] like Figures 14 to 20 A bottom plate structure that cooperates with a sink-needle needle plate is shown. It should be noted that the difference between this embodiment and Embodiment 1 lies in the structural features of the push-needle control mechanism 22 and the structural features of the guide mechanism 3107 in the first control mechanism in the control unit for driving the push-needle control mechanism 22.

[0110] like Fig.18 , Fig.19As shown, the needle pushing control mechanism 22 includes a set of knitting cam components and a set of needle receiving cam components, wherein the knitting cam components are in an eight-shaped structure, and the needle receiving cam components are in a Y-shaped structure and are arranged below the knitting cam components.

[0111] It should be noted that, in this embodiment, Fig.14 As shown, the knitting triangle assembly 2201 specifically includes knitting triangle C1 2206, knitting triangle C2 2207, knitting triangle C3 2208 and knitting triangle C4 2209 which are distributed in an eight-shaped structure. Among them, knitting triangle C1 and knitting triangle C2 are located at the top and are arranged symmetrically, while knitting triangle C3 and knitting triangle C4 are located at the bottom and are symmetrically located at the bottom and are respectively located on the oblique extension lines of the corresponding knitting triangle C1 and knitting triangle C2. It should also be noted that the knitting triangle C1, knitting triangle C2, knitting triangle C3 and knitting triangle C4 in this embodiment are all slidably inserted in the bottom plate 1 so that they can rise and fall on the bottom plate when under pressure.

[0112] At the same time, if Fig.14 As shown, the needle cam assembly 2214 includes a needle cam C1, and needle cams C2 2222 and C3 2223 symmetrically arranged on both sides of the needle cam C1 2221. The three needle cams form a Y-shaped structure and are slidably inserted in the bottom plate 1 to complete the lifting required for the knitting action under the drive of the guide mechanism. It should be noted that in this embodiment, the needle cam C1 is fixedly connected to the needle cam C2 and the needle cam C3 so that the three needle cams can form a synchronously lifted whole.

[0113] like Fig.18 , Fig.19As shown, in this embodiment, the guide mechanism 3107 for guiding the needle push control mechanism specifically includes a motor A3102 shared with the cam assembly 3101, and a guide gear 3108 is coaxially installed on the output shaft of the motor A that is not equipped with the cam. At the same time, a triangle control seat 3112 is fixedly installed on the bottom plate, and a plurality of sockets are provided on the triangle control seat, and a guide rod B 3111 is inserted in the socket in a sliding fit. It should be noted that these guide rods B are respectively fixedly connected to the knitting cam C1, knitting cam C2, knitting cam C3, knitting cam C4 in the knitting cam assembly and the needle receiving cam C1, needle receiving cam C2, needle receiving cam C3 in the needle receiving cam assembly. At the same time, a spring 3106 is sleeved on the guide rod B connected to the connecting knitting cam C1, knitting cam C2, knitting cam C3, and knitting cam C4. Through the action of the spring, when the connecting knitting cam C1, knitting cam C2, knitting cam C3, and knitting cam C4 are subjected to external pressure (force from the needle pusher), each knitting cam is in a state of extending to the surface of the bottom plate. At the same time, it should be noted that if Fig. 20 As shown, in order to ensure that the needle pusher can smoothly pass through the surfaces of the connecting knitting cam C1, knitting cam C2, knitting cam C3, and knitting cam C4 on the travel path, a needle running slope is also provided on the needle-incoming side of the connecting knitting cam C1, knitting cam C2, knitting cam C3, and knitting cam C4. The needle running slope is an inclined surface, and the bottom is smoothly connected to the surface of the bottom plate, so that the heel of the needle pusher can slide to the upper surface of the corresponding knitting cam through the needle running slope.

[0114] In addition, there is a horizontal slide groove on the triangle control seat 3112, in which a control plate C that can slide back and forth horizontally is inserted, and a plurality of tooth grooves are provided on the upper edge of the control plate C so as to mesh with the guide gear 3108 installed on the output shaft of the motor A, and the reciprocating rotation of the motor A can drive the reciprocating sliding of the control plate C. In addition, in the triangle control seat, the three guide rods B connected to the needle receiving cam have protruding parts on their sides, which extend to the side holes provided on the triangle control seat and then slide into the guide groove provided on the control plate C. In this embodiment, the guide groove is provided in an eight-shaped shape so that the guided guide rods B can drive the needle receiving cam connected thereto to achieve the lifting and lowering of the knitting action on the bottom plate.

[0115] It should be noted that, in this embodiment, the structures of the needle selection control mechanism and the second control mechanism are the same as those in Example 1, and therefore will not be described in detail.

[0116] like Figures 14 to 17 As shown, in this embodiment, when each cam performs a corresponding knitting action, the working mode on the bottom plate is as follows:

[0117] Knitting: When the machine head moves to the left, the transfer cam A is driven by the cam to the state of being retracted into the bottom plate surface, and the knitting cam assembly and the needle receiving cam assembly are both at zero position protruding from the bottom plate surface. The needle selection cam A1 is driven by the needle selection control board to the state of being protruding from the bottom plate surface, and the needle selection cam A2 is driven by the needle selection control board to the state of being retracted from the bottom plate surface, thereby realizing the knitting needle trajectory of the machine head moving to the left.

[0118] When the machine head moves right, the states of the other cams are the same as those of the machine head moving left, except that the needle selection cam A1 is retracted into the bottom plate surface and the needle selection cam A2 protrudes from the bottom plate surface, thereby realizing the right-moving knitting needle trajectory of the machine head.

[0119] Tuck: When the machine head moves to the left, the needle transfer cam A is driven by the cam to the state of being retracted on the bottom plate surface, the needle receiving cam C1 is driven by the control board C to the state of being retracted on the bottom plate surface, the needle receiving cam C2 is driven by the control board C to the state of being protruding on the bottom plate surface, and the needle selection cam A1 and the needle selection cam A2 are driven by the needle selection control board to the zero position, and both are in the state of being retracted on the bottom plate surface. This realizes the needle movement track of the machine head moving to the left.

[0120] When the machine head moves right, the actions of the other cams are the same as those of the machine head moving left, except that the needle cam C2 is retracted into the bottom plate surface, while the needle cam C1 is protruded from the bottom plate surface. This realizes the needle movement track of the machine head moving right.

[0121] Needle transfer: When the machine head moves to the left, the needle transfer cam A is driven by the cam to the state of retracting the bottom plate surface, the needle receiving cam C1 is driven by the control board C to the state of retracting the bottom plate surface, the needle receiving cam C2 is driven by the control board C to the state of protruding the bottom plate surface, the needle selection cam A1 is driven by the needle selection control board to the protruding bottom plate surface, and the needle selection cam A2 is driven by the needle selection control board to the retracted bottom plate surface. In this way, the needle movement track of the machine head moving to the left is realized.

[0122] When the machine head moves right, the actions of the other cams are the same as those of the machine head moving left, except that the needle receiving cam C1 is driven by the control board C to the state of protruding the bottom plate surface, the needle receiving cam C2 is driven by the control board C to the state of retracting the bottom plate surface, the needle selecting cam A1 is driven by the needle selecting control board to the retracted bottom plate surface, and the needle selecting cam A2 is driven by the needle selecting control board to the protruding bottom plate surface. In this way, the needle movement track of the machine head moving right is realized.

[0123] Needle connection: When the machine head moves to the left, the needle transfer cam A is driven by the cam to the state of being retracted on the bottom plate surface, the needle connection cam C1 is driven by the control board C to the state of being retracted on the bottom plate surface, the needle connection cam C2 is driven by the control board C to the state of being protruded on the bottom plate surface, and the needle selection cam A1 and the needle selection cam A2 are driven by the needle selection control board to the state of being retracted on the bottom plate surface. In this way, the needle movement track of the machine head moving to the left is realized.

[0124] When the machine head moves right, the other cams move in the same way as when the machine head moves left, except that the needle receiving cam C1 is driven by the control board C to a state of protruding from the bottom plate surface, the needle receiving cam C2 is driven by the control board C to a state of retracting from the bottom plate surface, and the needle selecting cam A1 and the needle selecting cam A2 are driven by the needle selecting control board to retract from the bottom plate surface. Thus, the needle movement track of the machine head moving right is realized. Example

[0125] like Figures 21 to 27 It should be noted that the difference between this embodiment and embodiment 1 lies in the structural features of the knitting needle control mechanism 21 and the needle pushing control mechanism 22, and the structural features of the first control mechanism in the control unit for driving the knitting needle control mechanism 21 and the needle pushing control mechanism 22.

[0126] Specifically, Fig.21 As shown, the needle control mechanism 21 includes a needle turning triangle C1 2105, a needle turning triangle C2 2106, a needle turning triangle C3 2107, and a needle turning triangle C4 2108. The above needle turning triangles form a herringbone structure and guide the running trajectory of the needle by lifting on the bottom plate. Specifically, the needle turning triangle C1 is located at the top of the needle control mechanism and is fixedly installed on the bottom plate by bolts, while the needle turning triangle C2 is located below the needle turning triangle C1 and can be lifted and slid into the bottom plate. As for the needle turning triangle C3 and the needle turning triangle C4, they are located at the lower position of the needle control mechanism and are symmetrically arranged on the left and right. The two are also slid into the bottom plate so that they can complete the lifting action on the bottom plate after being driven by the cam assembly. It should also be noted that the needle turning triangle C2, the needle turning triangle C3, and the needle turning triangle C4 are fixedly connected together so that they can maintain synchronous lifting after one of the needle turning triangles is pressed.

[0127] The specific mechanism of the cam assembly 3101 adapted thereto for controlling the lifting and lowering of the knitting needle control mechanism on the surface of the base plate includes a motor A3102 lying horizontally and fixed on the base plate 1. The motor A is a dual-output shaft motor, and a cam is fixedly mounted on the output shaft on one side of the motor A. At the same time, a cam control seat 3104 is fixedly mounted on the back of the base plate by bolts, and a plurality of sockets are provided on the cam control seat, and a plurality of guide rods A3105 are slidably inserted in these sockets. One end of these guide rods A is respectively fixedly connected to the needle turning triangle C2, needle turning triangle C3 and needle turning triangle C4 slidably inserted in the base plate 1, so as to guide the needle turning triangles in the knitting needle control mechanism to rise and fall along the axial direction of the guide rod A. At the same time, springs 3106 are also sleeved on the guide rod A, and these springs are in a compressed state, so that the springs can apply a thrust to the guide rod A to push the guide rod A toward the surface of the base plate. In addition, as Fig.25 , Fig.26As shown, after one end of one of the guide rods A extends out of the cam control seat, a groove is formed at the end, and the cam on the motor A is located in the groove, so that the side wall of the groove on the guide rod A is hooked on the guide wheel rim of the cam under the action of the spring. When the cam rotates driven by the motor A, the guide wheel rim applies thrust to the groove wall of the guide rod A, thereby driving the guide rod A to rise and fall, and finally driving the needle transfer cam C2, needle transfer cam C3, and needle transfer cam C4 in the knitting needle control mechanism to rise and fall synchronously.

[0128] In addition, if Fig.21 As shown, in this embodiment, the needle push control mechanism 22 includes a set of knitting cam components 2201 and a set of needle receiving cam components 2214. The knitting cam is in an eight-shaped structure, and the needle receiving cam is in a Y-shaped structure. It should be noted that the needle receiving cam component is located below the knitting cam component and cooperates with the knitting cam to guide the running trajectory of the needle push piece.

[0129] Specifically, the knitting cam assembly 2201 includes a knitting cam D1, a knitting cam D2, a knitting cam D3, and a knitting cam D4 which are slidably inserted in the base plate 1. Among them, the knitting cam D1 and the knitting cam D2 are located in the upper part of the knitting cam assembly, and the two are symmetrically arranged, while the knitting cam D3 and the knitting cam D4 are located in the lower part of the knitting cam assembly, and are arranged along the extension line of the figure eight. It should also be noted that in this embodiment, the lifting state of the knitting cam is controlled by the pressure on the surface of the cam. Therefore, in order to guide the heel of the needle pusher to pass smoothly through the surface of the knitting cam, the needle-moving inclined surface which is smoothly connected to the surface of the base plate is arranged on the needle-incoming side of the knitting cam D1, the knitting cam D2, the knitting cam D3, and the knitting cam D4.

[0130] At the same time, Fig.21 As shown, the needle triangle assembly 2214 specifically includes a needle triangle D1, a needle triangle D2 and a needle triangle D3 which are slidably inserted in the bottom plate. The needle triangle D1 is located in the middle of the needle triangle assembly, while the needle triangle D2 and the needle triangle D3 are arranged on the left and right sides of the needle triangle D1. In addition, it should be noted that in this embodiment, the completion of the lifting action of each needle triangle during operation needs to be achieved by applying pressure to the surface of each needle triangle. For this reason, a needle running slope is provided on the needle side of the needle triangle D1, the needle triangle D2 and the needle triangle D3. Specifically, when the needle triangle D1, the needle triangle D2 and the needle triangle D3 extend out of the bottom plate surface, the lower edge of the needle running slope is smoothly connected with the bottom plate surface, so that the heel of the needle pusher can slide smoothly to the needle triangle surface passed by.

[0131] And corresponding to it, such as Fig.25 , 26As shown, in this embodiment, the guide mechanism 3107 for driving the push pin control mechanism 22 includes a motor A3102 shared with the cam assembly 3101, and a guide gear 3108 is installed on the end of the dual output shaft motor where the cam is not installed. Fig.25 As shown, a triangle control seat 3112 is also fixedly installed on the base plate 1 by bolts, and a plurality of sockets are provided on the triangle control seat, and a guide rod B3111 is inserted in the socket in a sliding manner. It should be noted that in the present embodiment, there are seven guide rods B, and they are fixedly connected to the knitting triangle D1, knitting triangle D2, knitting triangle D3, knitting triangle D4, and the needle triangle D1, needle triangle D2, and needle triangle D3 in a one-to-one correspondence. At the same time, a spring 3106 is sleeved on each guide rod except the one connected to the needle triangle D1, so as to support the guide rod B through the spring. Specifically, under the support of the spring, the knitting triangle D1, knitting triangle D2, knitting triangle D3, knitting triangle D4, and the needle triangle D2 and needle triangle D3 connected to the guide rod B are all extended on the surface of the base plate when not under pressure. The guide rod B connected to the reception triangle D1 extends out of the triangle control seat. It should be noted that a slide groove is also provided on the triangle control seat, in which a control plate D3114 capable of reciprocating horizontal sliding is slidably inserted, and a "J"-shaped guide groove is provided on the control plate D. The guide rod B connected to the receiving needle triangle D1 passes through the triangle control seat and is inserted into the guide groove in a sliding manner. When the control plate moves reciprocatingly horizontally, the guide rod B is driven to rise and fall through the undulating guide groove, thereby driving the receiving needle triangle D1 connected to the guide rod B to rise and fall synchronously.

[0132] It should be noted that, in this embodiment, the structures of the needle selection control mechanism and the second control mechanism are the same as those in Example 1, and therefore will not be described in detail.

[0133] like Figures 21 to 24 As shown, in this embodiment, when each cam performs a corresponding knitting action, the working mode on the bottom plate is as follows:

[0134] Knitting: When the machine head moves to the left, the transfer cam D2 is driven by the cam to the state of being retracted into the bottom plate surface. When the transfer cam D2 is retracted into the bottom plate surface, the transfer cams D3 and D4 are retracted into the bottom plate surface together. The needle selection cam A1 is driven by the needle selection control board to protrude from the bottom plate surface, and the needle selection cam A2 is driven by the needle selection control board to the state of being retracted from the bottom plate surface. The remaining knitting cam components are in the state of protruding from the bottom plate surface, thereby realizing the knitting needle trajectory of the machine head moving to the left.

[0135] When the machine head moves right, the positions of the other cams are the same as the positions of the left cams. In addition to the needle selection cam A1 being driven by the needle selection control board to the state of being retracted into the bottom plate surface, the needle selection cam A2 is driven by the needle selection control board to the state of being protruded from the bottom plate surface. This realizes the needle movement track of the machine head moving right.

[0136] Tuck: When the machine head moves to the left, the transfer cam D2 is driven by the cam to the state of being retracted into the bottom plate surface. When the transfer cam D2 is retracted into the bottom plate surface, the transfer cams D3 and D4 are retracted into the bottom plate surface together. The needle selection cam A1 and the needle selection cam A2 are both driven by the needle selection control board to the state of being retracted into the bottom plate surface, thereby realizing the needle movement track of the machine head moving to the left.

[0137] When the loom moves right, the other triangles move in the same way as when the loom moves left, thus realizing the loom's needle movement track for right-moving looms.

[0138] Needle transfer: When the machine head moves to the left, the needle transfer cam D2 is driven by the cam to a state of protruding from the bottom plate surface. The needle selection cam A1 is driven by the needle selection control board to a state of protruding from the bottom plate surface, and the needle selection cam A2 is driven by the needle selection control board to a state of retracting from the bottom plate surface. This realizes the needle transfer trajectory of the machine head moving to the left.

[0139] When the machine head moves right, the actions of the other cams are the same as those of the machine head moving left, except that the needle selection cam A1 is driven by the needle selection control board to a retracted bottom plate state, and the needle selection cam A2 is driven by the needle selection control board to a protruding bottom plate state, thereby realizing the needle movement trajectory of the machine head moving right.

[0140] Needle connection: When the machine head moves to the left, the needle transfer cam D2 is driven by the cam to a state of protruding from the bottom plate surface. The needle selection cam A1 and the needle selection cam A2 are driven by the needle selection control board to a state of retracting into the bottom plate surface, thereby realizing the needle connection and needle movement trajectory of the machine head moving to the left.

[0141] When the machine head moves right, the other cams move in the same way as when the machine head moves left, and the needle selection cam A1 and the needle cam A2 are driven by the needle selection control board to the state of retracting into the bottom plate surface, thereby realizing the needle movement trajectory of the machine head moving right.

[0142] It should be noted that in the above four embodiments, the control of the needle control mechanism by the cam assembly in the first control mechanism and the control of the needle pusher control mechanism by the guide mechanism can be realized independently, and the common part of the two is only the motor A. Therefore, in the above four embodiments, if the needle control mechanism and the cam assembly are taken as a whole, and the needle pusher control mechanism and the guide mechanism are taken as another whole, the corresponding parts of each embodiment can be interchanged to further enhance the structural form of the present application scheme. Specifically: the overall structure formed by the needle control mechanism and the cam assembly in Example 1 can be interchanged with the corresponding structures in Examples 2, 3 and 4, and the overall structure formed by the needle pusher control mechanism and the guide mechanism in Example 1 can also be interchanged with the corresponding structures in Examples 2, 3 and 4. In addition, the structures in Examples 2, 3 and 4 can also be interchanged with the corresponding structures in other embodiments.

[0143] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
