[0002] The existing flat knitting machines generally have only one head on a needle bed, which may include one or more cam systems. During knitting, the multiple cam systems can only move together at the same time, and it is impossible to knit multiple parts at the same time. Especially for large flat knitting machines, the lateral width of the knitted clothes is generally very long, and the knitting stroke of the entire head to complete the knitting will be very long, resulting in low knitting efficiency. For example, in a fully formed sweater flat knitting machine, the two sleeves and the body are separated by a long distance on the entire needle plate. Under the existing technical conditions, one head can only knit the left sleeve, the body, and the right sleeve in turn, resulting in a very long knitting stroke and extremely low knitting efficiency.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] For large-scale flat knitting machines, the horizontal length of the clothes they knit is generally very long, and the existing flat knitting machines generally have only one head that cooperates with the corresponding needle plate to knit along the knitting direction. Because the horizontal length of the overall clothing is longer than that of knitted fabrics such as gloves, for example, knitted sweaters, one head can only knit the left sleeve, the body, and the right sleeve in turn, which will directly lead to a relatively long stroke for the head to complete the entire knitting, thereby resulting in low overall knitting efficiency and indirectly increasing the knitting cost.

[0023] like Figure 1-4As shown, an embodiment of the utility model provides a horizontal knitting machine with high knitting efficiency, wherein the knitting machine comprises a frame 1, on which a plurality of needle plates 2 are arranged, which are generally arranged in pairs, and a sliding rod 3 is arranged on the front side of each needle plate 2 along the weaving direction, and the sliding rod 3 is fixed on the frame 1. In order to solve the above-mentioned problem, a head assembly is slidably arranged on the sliding rod 3 on the front side of each needle plate 2, and the head assembly corresponding to each of the above-mentioned needle plates 2 includes a plurality of first heads 4. Because each head has at least one triangle system that can participate in the complete knitting, each first head 4 can slide on the sliding rod 3 and cooperate with the needle plate 2 to complete the weaving of the fabric. A plurality of first heads 4 are correspondingly arranged on each needle plate 2. During the weaving process, more than two heads can be used to slide on the sliding rod 3 and cooperate with the corresponding needle plate 2 to complete the weaving of the fabric. Compared with weaving with one head, it can speed up the weaving efficiency and more fabrics can be woven at the same time; and a plurality of independent driving components 5 are also arranged on the frame 1, wherein each first head 4 corresponding to the same needle plate 2 is connected to the corresponding driving component 5, so that the plurality of first heads 4 corresponding to the same needle plate 2 are driven by the plurality of driving components 5 to perform weaving work, and the plurality of driving components 5 can work synchronously, or work asynchronously, or work partially synchronously, etc. under the control of the control program in the external controller, so that the plurality of first heads 4 in the same needle plate 2 have three motion modes, namely, synchronous mode, independent mode and gap mode. When weaving, the plurality of heads in the same needle plate 2 can be weaved in a motion mode that meets the requirements according to different knitted fabrics and weaving requirements, so that it is more convenient for users to use.

[0024] Specifically, the synchronization mode mentioned above can be understood as the first heads 4 participating in the synchronization mode maintaining the same speed and moving together with a fixed relative position difference; there are multiple application modes, for example: 1. For certain fabrics, such as the sealing of gloves and the four-level fabric of sweaters, the synchronization mode needs to be adopted when the turning needle moves; 2. When the fabric is narrow enough and the needle plate 2 is long enough, multiple first heads 4 have synchronization modes, and each first head 4 corresponds to weaving a piece of fabric, then multiple fabrics can be woven at the same time, and more pieces of fabric can be woven in the same time. For example, if two driving components 5 are started at the same time, the corresponding two first heads 4 move, and two pieces of fabric are woven at one time; 3. Multiple first heads 4 can be combined into a head with more systems for use, such as two heads of a single system can be synchronized and used as a head of a dual system, etc. Of course, in the above-mentioned usage mode, no matter which application mode is used, the weaving efficiency can be accelerated.

[0025] The independent mode mentioned above means that different parts of a fabric are located in different areas of the needle plate 2, and there is no overlapping area between the areas. Multiple first heads 4 cooperate with different areas of the needle plate 2 to weave different parts of the fabric at the same time. There is no possibility of interference between the first heads 4, and each weaves independently according to its own acceleration, speed, and position. Compared with one head weaving different parts of the fabric in sequence, the weaving speed is faster and the efficiency is higher; the gap mode mentioned above refers to a movement mode in which all the first heads 4 involved in weaving ensure that the minimum position difference between any two heads is greater than a set value within the set weaving area, so as to stabilize the weaving.

[0026] Taking the front and rear two needle plates 2, each needle plate 2 having three first heads 4 participating in the full-formed sweater knitting as an example, the sweater knitted fabric is divided into the left sleeve, the body and the right sleeve from left to right. The front left first head 4 and the rear left first head 4 are responsible for knitting the left sleeve, the front middle first head 4 and the rear middle first head 4 are responsible for the body, and the front right first head 4 and the rear right first head 4 are responsible for the right sleeve. If the positions of the three sections are separated by a large distance, the left, middle and right three groups of heads can adopt an independent motion mode. When the position interval is small, the gap mode should be adopted. The front left head and the rear left head can adopt the synchronous mode or the gap mode when knitting the left sleeve, and the same is true for the front middle and the rear middle, and the front right and the rear right.

[0027] Of course, the drive components 5 corresponding to the first heads 4 that are not involved in weaving do not work. For the first heads 4 that are involved in weaving, if some of the first heads 4 end weaving prematurely, the drive components 5 corresponding to them will also stop working to save energy. Moreover, the independence of multiple drive components 5 means that the installation positions do not interfere with each other. As for the driving mode of the multiple drive components 5, it can be determined by the control program in the external controller.

[0028] The connection between the drive assembly 5 and the first head 4 is various. In the present embodiment, the number of the drive assemblies 5 is equal to the number of the first heads 4 and they are connected one by one, so that each first head 4 will be connected to a drive assembly 5. Specifically, in the present embodiment, the drive assembly 5 can be a drive mechanism on an existing flat knitting machine, specifically including a motor 51, a conveyor belt assembly and a connecting plate 55. The conveyor belt assembly includes a driving wheel 52, a conveyor belt 54 and a driven wheel 53. The motor 51 is mounted on the frame 1, and the output shaft of the motor 51 is connected to the driving wheel 52. The conveyor belt 54 is mounted on the driving wheel 52 and the driven wheel 53. The connecting plate 55 is mounted on the frame 1. It is mounted on the conveyor belt 54, and the connecting plate 55 is connected to the outer side wall of the corresponding first machine head 4, so that the motor 51 can drive the connecting plate 55 and the first machine head 4 to move together through the conveyor belt 54. When the driving component 5 adopts this driving mode, the multiple driving components 5 corresponding to each needle plate 2 can be arranged in sequence on the frame 1. Of course, the connecting plate 55 on the back side should be designed with a corresponding avoidance groove to avoid the conveyor belt 54 on the front side, so that the conveyor belt 54 on the front side can run stably. For example, three first machine heads 4 are correspondingly arranged on each needle plate 2, and three driving components 5 and two needle plates 2 are correspondingly arranged on each needle plate 2. The arrangement method is as follows Figure 3 As shown, they are arranged in sequence on the frame 1 on one side of the needle plate 2.

[0029] In another embodiment, a first head 4 is extracted from each of the different head assemblies to form a first head group, and the number of the first head groups is the same as the number of the driving assemblies 5, so that the multiple first head groups are connected to the multiple driving assemblies 5 in a one-to-one correspondence, so that the driving assembly 5 can drive the first head group to move, that is, to drive the first heads 4 in different head assemblies to move simultaneously, and weave the fabrics on the corresponding needle plates 2 at the same time. In this embodiment, the driving assembly 5 includes a motor 51, a conveyor belt assembly and a connecting plate 55, and the conveyor belt assembly includes a driving wheel 52, a conveyor belt 54 and a driven wheel 53. The motor 51 is installed on the frame 1, and the output shaft of the motor 51 is connected to the driving wheel 52. The conveyor belt 54 is installed on the driving wheel 52 and the driven wheel 53. The connecting plate 55 is installed on the conveyor belt 54. The connecting plate 55 is connected to the outer side wall of the corresponding first head 4 on one of the needle plates 2, and the first heads 4 in the first head group are connected to each other. They are connected through a sky bridge 56, so that the first heads 4 corresponding to different needle plates 2 are controlled to move simultaneously and participate in weaving synchronously, and the multiple first heads 4 corresponding to the same needle plate 2 are still connected through multiple motors 51, and the multiple motors 51 still have a synchronous mode, an independent mode and a gap mode. Therefore, the drive component 5 adopts this drive structure. Compared with the above-mentioned embodiment in which each first head 4 is connected through a drive component 5, the use of a lot of motors 51 is saved, and the use cost is saved to a certain extent. The above-mentioned sky bridge 56 can be a gate-shaped connecting rod, as long as the two corresponding first heads 4 can be connected together and move simultaneously; when the drive component 5 adopts this driving mode, multiple drive components 5 can be arranged in sequence on the frame 1. Taking the example of each needle plate 2 being provided with three first heads 4, each needle plate 2 being provided with three drive components 5 and two needle plates 2, the arrangement method is as follows Figure 4 As shown, for a flat knitting machine with more than two needle plates 2, it is only necessary to connect the corresponding first machine heads 4 on the two needle plates 2 through the bridge 56, and the drive assembly 5 is as shown in FIG. Figure 4 As shown, it only needs to be set on the frame in front of one of the needle plates and arranged in sequence.

[0030] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
