According to its development, flat knitting machines include hand-cranked flat knitting machines, semi-automatic flat knitting machines, and computerized flat knitting machines. Due to the wide variety of woolen clothing patterns, computerized flat knitting machines need to change and knit yarns of multiple colors or multiple yarns, so the color changing device is one of the important accessories of the flat knitting machine.

[0003] For example, a motor-driven color-changing mechanism disclosed in the publication number "CN 217869367U" includes a main base and at least two switching components arranged in parallel on the main base, the switching components including: a driving motor, arranged on the rear side of the main base, and its output end is arranged vertically upward; a cylindrical cam, arranged on the driving motor and connected to the output end of the driving motor; a slide bar, two slide bars are movably inserted and arranged in the main base; a knock rod body, two knock rod bodies are relatively and rotatably arranged on the main base, one end of the knock rod body is in contact with the cylindrical cam, and the other end of the knock rod body penetrates into the main base and in contact with the slide bar, and the knock rod body is used to drive the slide bar to perform vertical lifting and lowering movements; an elastic body, the elastic body is arranged at the bottom of the slide bar and connected to the main base.

[0004] However, during the color changing process, the existing color changing mechanism lacks a guide structure on the base to guide the slide bar, which causes the slide bar to easily get stuck on the base, resulting in the failure of the flat knitting machine to change colors and affecting the knitting quality and knitting efficiency. Utility Model Content

[0005] In order to solve the technical problems existing in the background technology, the utility model proposes a color-changing base.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0007] A color-changing base comprises a base, and a plurality of color-changing modules arranged at intervals on the base;

[0008] The color-changing module comprises a slider slidably arranged on a base, a retracting assembly driving the slider to retract in the base, and an elastic element for pushing the slider out of the base;

[0009] The base body is formed with a plurality of sliding grooves, the sliding blocks are slidably arranged in the sliding grooves, and a roller group is rotatably arranged in the sliding grooves, and the sliding blocks slide on the roller group.

[0010] Preferably, the folding assembly includes an abutment arm rotated on the base, and an electromagnet driving the abutment arm to rotate. When the electromagnet is energized, it brakes one end of the abutment arm to tilt up, so that the other end of the abutment arm drops and abuts the slider, forcing the slider to be retracted into the base. Through the above improvements, when the electromagnet is energized, one end of the abutment arm is pushed up, the other end of the abutment arm is dropped, and the slider is pressed down, so that the slider is retracted into the base, thereby realizing the color-changing function.

[0011] Preferably, an abutment groove is formed on the slider, and one end of the abutment arm is inserted into the abutment groove. Through the above improvement, when the abutment arm rotates, the part of the abutment arm inserted into the abutment groove will act on the abutment groove, thereby driving the slider to move downward and retract it into the sliding groove, thereby achieving color change.

[0012] Preferably, the roller group includes at least two pulleys that can rotate independently. Through the above improvements, multiple pulleys can slide independently to avoid the situation where a single pulley is stuck. There are other pulleys to slide to avoid the situation where the slider is stuck. In addition, it is easier to install on the base than using a single pulley with a larger width.

[0013] Preferably, a rotation groove is formed on the base, and the pulley is placed in the rotation groove. Through the above improvement, the pulley is prevented from being offset to the left and right, thereby improving the stability of the slider during sliding.

[0014] Preferably, the sliding grooves are arranged in pairs and adjacent to each other, a first installation shaft is arranged in the sliding groove, an embedding groove is formed in the sliding groove, the first installation shaft is embedded in the embedding groove, and the sliding groove is connected to adjacent sliding grooves, a fixed groove is arranged between the sliding grooves, a locking block is embedded in the fixed groove, and the locking block restricts the first installation shaft from leaving the fixed groove. Through the above improvements, the stability of the installation of the first installation shaft is improved, and the two sliding grooves share one first installation shaft, which reduces the number of parts and improves the convenience of assembly. The stability of the first installation shaft is ensured by the locking block, and the reliability of the roller group during use is ensured.

[0015] Preferably, a limiting groove is provided on the base, and a limiting plate is embedded in the limiting groove to limit the slider from escaping from the sliding groove. Through the above improvements, the slider is prevented from escaping from the base during the sliding process, thereby ensuring the reliability of the slider during the sliding process.

[0016] Preferably, a travel groove is formed on the slider, the limit plate is placed in the travel groove, and when the slider is extended or retracted in the base, the limit plate abuts against the travel groove. Through the above improvement, the travel of the travel groove limits the distance that the slider moves up and down. When the slider moves a specified distance, the travel groove will abut against the limit plate to prevent the slider from continuing to move, thereby ensuring the accuracy of the slider's moving distance, thereby ensuring the accuracy of color change.

[0017] Preferably, a first mounting hole is formed on the base for inserting one end of the elastic element, and a second mounting hole is formed at the bottom of the slider for inserting the other end of the elastic element. Through the above improvements, the stability of the installation of the elastic element is ensured, and the stability of the slider during the up and down movement is improved.

[0018] Preferably, a guide plate is provided on the base, and a guide opening is formed on the guide plate for the slider to extend out. Through the above improvement, the slider is guided, thereby improving the stability of the slider during the upward movement.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0029] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0030] like Figure 1-6 As shown, a color-changing base includes a base 1, and a plurality of color-changing modules 2 arranged at intervals on the base 1;

[0031] Specifically, the color-changing module 2 includes a slider 101 slidably disposed on the base 1 , a retracting assembly 102 for driving the slider 101 to be retracted into the base 1 , and an elastic element 103 for pushing the slider 101 out of the base 1 .

[0032] Furthermore, a plurality of sliding grooves 104 are formed on the base body 1 , and the slider 101 is slidably disposed in the sliding groove 104 . A roller group 106 is rotatably disposed in the sliding groove 104 , and the slider 101 slides on the roller group 106 .

[0033] During the use of the entire color-changing module 2, when a certain color of silk thread is needed, the retracting component 102 that controls the slider 101 under the silk thread of this color no longer acts on the slider 101, and the slider 101 extends out of the base under the action of the elastic element 103, and the slider 101 of this color is lifted up. When the silk thread of this color is not needed, the retracting component 102 presses the slider 101 downward to retract it into the base 1, causing the silk thread to drop, thereby realizing the color-changing function.

[0034] In addition, the slider 101 is set in the sliding groove 104 of the base 1, and the slider 101 slides on the roller group 106, which greatly improves the smoothness of the slider 101 during movement and avoids the slider 101 from getting stuck or stuck during sliding, thereby improving the reliability of the entire color changing structure, thereby improving the knitting quality and knitting efficiency of the entire flat knitting machine.

[0035] As a further explanation of the installation of the roller assembly 106 , a first installation shaft 105 is disposed in the sliding groove 104 , and the roller assembly 106 is rotatably disposed on the first installation shaft 105 , thereby improving the smoothness of the rotation of the roller assembly 106 .

[0036] like Figure 2 , Figure 3 As shown, further explanation of the implementation method of the folding component 102 in this embodiment, wherein the folding component 102 includes an abutment arm 201 rotated on the base 1, and an electromagnet 202 for driving the abutment arm 201 to rotate. When the electromagnet 202 is energized, it brakes one end of the abutment arm 201 to lift up, so that the other end of the abutment arm 201 descends and abuts the slider 101, forcing the slider 101 to be retracted into the base 1.

[0037] Specifically, a second mounting shaft 203 is provided on the base 1, and the abutment arm 201 is rotatably provided on the second mounting shaft 203. The electromagnet 202 includes an electromagnet body 204, and a top block 205 movably provided in the electromagnet body 204. When the electromagnet 202 is energized, the top block 205 rises and lifts one end of the abutment arm 201, and the other end of the abutment arm 201 descends and abuts against the slider 101, so that the slider 101 is retracted into the base 1.

[0038] During the use of the entire color-changing structure, when the electromagnet 202 is energized, the top block 205 will rise under the action of the electromagnet 202, thereby pushing up one end of the abutment arm 201, and causing the other end of the abutment arm 201 to drop, and pressing down the slider 101, so that the slider 101 is retracted into the base 1, and when the electromagnet 202 is powered off, the top block 205 will drop, so that the slider 101 lacks the pressure of the abutment arm 201, and will extend out of the base 1 under the action of the elastic element 103, thereby realizing the color-changing function.

[0039] Specifically, an abutment groove 206 is formed on the slider 101, and one end of the abutment arm 201 is inserted into the abutment groove 206. When the abutment arm 201 rotates, the part of the abutment arm 201 inserted into the abutment groove 206 will act on the abutment groove 206, thereby driving the slider 101 to move downward and make it retract into the sliding groove 104, thereby realizing color change.

[0040] like Figure 3 , Figure 4 , Figure 5 As shown, as a further explanation of the implementation method of the roller group 106 in this embodiment, the roller group 106 includes at least two pulleys 301 that can rotate independently, and multiple pulleys 301 can slide independently to avoid the situation where a single pulley 301 is stuck. There are other pulleys 301 to slide to avoid the slider 101 from getting stuck, and compared with using a single pulley 301 with a larger width, it is easier to install on the base 1.

[0041] Specifically, a rotation groove 302 is formed on the base 1 , and the pulley 301 is placed in the rotation groove 302 to prevent the pulley 301 from shifting left and right, thereby improving the stability of the slider 101 during sliding.

[0042] Furthermore, the sliding grooves 104 are grouped in pairs and arranged adjacent to each other, an embedding groove 303 is formed in the sliding groove 104, a first installation shaft 105 is provided in the sliding groove 104, the first installation shaft 105 is embedded in the embedding groove 303, and the sliding grooves 104 are connected to adjacent sliding grooves 104, a fixed groove 304 is provided between the sliding grooves 104, a locking block 305 is embedded in the fixing groove 304, and the locking block 305 limits the first installation shaft 105 from detaching from the fixing groove 304.

[0043] The first installation shaft 105 is embedded in the embedding groove 303, which improves the stability of the installation of the first installation shaft 105. The two sliding grooves 104 share one first installation shaft 105, which reduces the number of parts and improves the convenience of assembly. The first installation groove is locked on the base 1 by the locking block 305, which ensures the stability of the first installation shaft 105 and the reliability of the roller assembly 106 during use.

[0044] like Figure 4 , Figure 5 As shown, in some other embodiments, a limiting groove 401 is provided on the base 1, and a limiting plate 402 is embedded in the limiting groove 401 to limit the slider 101 from disengaging from the sliding groove 104, thereby preventing the slider 101 from disengaging from the base 1 during the sliding process, thereby ensuring the reliability of the slider 101 during the sliding process.

[0045] Furthermore, a travel groove 403 is formed on the slider 101 , and the limit plate 402 is inserted into the travel groove 403 . When the slider 101 is extended or retracted into the base 1 , the limit plate 402 abuts against the travel groove 403 .

[0046] The travel of the travel groove 403 is used to limit the distance that the slider 101 moves up and down. When the slider 101 moves a specified distance, the travel groove 403 will abut against the limit plate 402 to prevent the slider 101 from continuing to move, thereby ensuring the accuracy of the moving distance of the slider 101 and thus ensuring the accuracy of color changing.

[0047] like Figure 4 As shown, preferably, a first mounting hole 501 for inserting one end of the elastic element 103 is formed on the base 1, and a second mounting hole 502 for inserting the other end of the elastic element 103 is formed at the bottom of the slider 101, thereby ensuring the stability of the installation of the elastic element 103 and improving the stability of the slider 101 during the up and down movement.

[0048] In addition, two elastic elements 103 are arranged between the base 1 and the slider 101 , and are respectively arranged on both sides of the bottom of the slider 101 , thereby further improving the stability of the slider 101 during the upward sliding process.

[0049] like Figure 4 As shown, preferably, a guide plate 503 is provided on the base 1, and a guide opening 504 is formed on the guide plate 503 for the slider 101 to extend out. The guide opening 504 guides the slider 101 during the extension process, thereby improving the stability of the slider 101 during the ascending process.

[0050] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention.
