[0012] Furthermore, the drive bracket includes a mounting plate and a connecting column. The mounting plate is mounted on the frame via the connecting column, and a connection space is formed between the mounting plate and the frame.

[0013] Furthermore, the drive bracket also includes a first bearing mounted on the mounting plate; the frame includes a second bearing mounted on the frame plate, the first bearing and the second bearing are coaxially arranged, and both the first bearing and the second bearing are connected to the connector, thereby improving the installation stability of the connector.

[0014] Furthermore, the fabric winding device of the computerized flat knitting machine also includes a sensor, which is installed on the frame along the first direction and is spaced apart from the fabric winding tube.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] like Figure 1 As shown, in one implementation, this application provides a fabric winding device for a computerized flat knitting machine, including a frame 1, two connectors 2, a fabric winding tube 3, a drive assembly 4, and a limiting member 5. The two connectors 2 are used to transition the fabric winding tube 3 to the frame 1. The fabric winding tube 3 is used to wind the fabric produced by the computerized flat knitting machine. The drive assembly 4 is used to drive one of the connectors 2 to rotate, thereby winding the fabric to the fabric winding tube 3. The limiting member 5 is used to limit the fabric winding tube 3 within the connectors 2.

[0023] Specifically, the frame 1 includes two frame plates 101, which are parallel to each other and spaced apart, so as to facilitate the installation of the connector 2 and the fabric roll tube 3 between the adjacent frame plates 101.

[0024] Two connectors 2 are installed along the first direction on the two frame plates 101 of the frame 1, that is, both connectors 2 are located between two adjacent frame plates 101.

[0025] Both connectors 2 have rotational freedom relative to the frame 1, and the rotation axes of the two connectors 2 are coaxial, ensuring the rotational stability of the fabric roll tube 3.

[0026] It should be noted that the rotation axes of both connectors 2 are parallel to the first direction.

[0027] like Figure 2 and Figure 3As shown, both ends of the two connectors 2 facing the fabric roll tube 3 include mounting grooves 201. Along the first direction, both ends of the fabric roll tube 3 are respectively installed in the mounting grooves 201 of the two connectors 2, and the fabric roll tube 3 and the two connectors 2 rotate simultaneously.

[0028] The drive assembly 4 is mounted on the frame 1 and is connected to one of the connectors 2, which drives it to rotate, thereby causing the fabric roll tube 3 and the other connector 2 to rotate simultaneously.

[0029] Two limiting members 5 are respectively installed on the two connecting members 2 along the third direction, and the ends of the roll tube 3 are limited in the mounting groove 201 by the two limiting members 5.

[0030] The mounting groove 201 includes a first opening 2011 and a second opening 2012. Along the first direction, the first opening 2011 is located at the end of the mounting groove 201 facing the roll tube 3, and along the second direction, the second opening 2012 is located on one side of the mounting groove 201.

[0031] The first opening 2011 facilitates the extension of the end of the fabric roll tube 3 into the mounting groove 201, preventing interference between the fabric roll tube 3 and the connector 2. The second opening 2012 facilitates the installation of the fabric roll tube 3 into the mounting groove 201 along the second direction, thereby improving the ease of installation and removal of the fabric roll tube 3 and the connector 2.

[0032] The limiting component 5 opens or closes the second opening 2012.

[0033] When the limiting member 5 separates from the connecting member 2, the second opening 2012 opens, and the roll tube 3 can be taken out from the mounting groove 201 through the second opening 2012 in the second direction.

[0034] When the limiting member 5 is installed on the connector 2, the second opening 2012 closes, thereby locking the end of the roll tube 3 in the mounting groove 201 to prevent the roll tube 3 from separating from the connector 2, so that the roll tube 3 can rotate under the action of the drive assembly 4.

[0035] The second opening 2012 and the limiting piece 5 are used to disassemble and assemble the fabric roll tube 3, which improves the ease of disassembly and assembly of the fabric roll tube 3, thereby improving the production efficiency of the computerized flat knitting machine.

[0036] To more clearly illustrate the technical solution of this application, the following definitions are provided: Figure 1 The directions shown are up, down, left, and right. The first direction is... Figure 1 The left and right directions are shown. The second direction is... Figure 1 The vertical direction is shown. The third direction is... Figure 1 The front and back directions are shown. It should be noted that the first, second, and third directions are perpendicular to each other.

[0037] like Figure 2 and Figure 3 As shown, in one implementation, the two connectors 2 have the same structure, both including a mounting part 203 and a rotating shaft part 204. Along the first direction, the rotating shaft part 204 is connected to one side of the mounting part 203, and the rotating shaft part 204 is rotatably connected to the frame 1, so as to facilitate the rotatable installation of the connector 2 to the frame 1.

[0038] The mounting groove 201 is located on the side of the mounting section 203 facing the fabric roll tube 3.

[0039] Specifically, the rotating shaft 204 is a shaft structure, and the mounting part 203 is a quick-release structure, so as to form a mounting groove 201 on the mounting part 203.

[0040] As one implementation method, along the first direction, the maximum distance between the second openings 2012 of the two connectors 2 is greater than or equal to the size of the fabric roll tube 3, ensuring that the fabric roll tube 3 can be stably installed into the mounting slots 201 of the two connectors 2, thereby improving the convenience of assembling and disassembling the fabric roll tube 3.

[0041] When installing the two connectors 2 onto the frame 1, the maximum distance between the second openings 2012 of the two connectors 2 is changed by adjusting the relative position of the rotating shaft 204 and the frame plate 101, so as to ensure that the maximum distance between the second openings 2012 of the two connectors 2 is greater than or equal to the size of the roll tube 3.

[0042] like Figure 2 As shown, as one implementation, a retaining ring 205 is installed on the rotating shaft 204. The retaining ring 205 is positioned close to (or abuts against) the frame plate 101. The retaining ring 205 facilitates axial positioning of the rotating shaft 204 and improves the installation stability of the connecting piece 2.

[0043] As one implementation, the connector 2 includes a mounting hole 202. Along a third direction, the mounting hole 202 penetrates the connector 2. The limiting member 5 is installed in the mounting hole 202 by a thread, which facilitates the disassembly and assembly of the limiting member 5, thereby further improving the ease of disassembly and assembly of the roll tube 3 and the connector 2.

[0044] Specifically, the mounting groove 201 includes a groove bottom surface 2014, and along the second direction, the groove bottom surface 2014 and the second opening 2012 are located on both sides of the mounting groove 201.

[0045] The distance between the mounting hole 202 and the bottom surface 2014 of the groove is consistent with the dimension of the fabric roll tube 3 along the second direction, so as to prevent the fabric roll tube 3 from shaking during rotation.

[0046] like Figure 2As shown, as one implementation, the limiting member 5 includes a screw 501 and a handle 502. Along a third direction, the handle 502 is installed at the end of the screw 501, further improving the ease of disassembly and assembly of the limiting member 5.

[0047] When installing the limiting member 5, the screw 501 is rotated by the handle 502, thereby installing the screw 501 into the connector 2 and closing the second opening 2012 by the screw 501.

[0048] like Figure 2 and Figure 3 As shown, as one implementation method, a finite surface 2013 is formed within the mounting slot 201.

[0049] The fabric roll tube 3 has an installation surface 301, which abuts against the limiting surface 2013, thereby limiting the end of the fabric roll tube 3 in the installation groove 201, so that the connector 2 and the fabric roll tube 3 rotate simultaneously.

[0050] Specifically, along the third direction, limiting surfaces 2013 are formed on both sides of the mounting groove 201.

[0051] Along the first direction, the projection of the fabric roll tube 3 is a square, that is, the fabric roll tube 3 is a regular square prism structure, so that all four sides of the fabric roll tube 3 are mounting surfaces 301.

[0052] The fabric roll tube 3, which is a regular square prism, makes it easy to roll the fabric onto the roll tube 3.

[0053] As one implementation method, along the first direction, the center line of the fabric roll tube 3 is coaxial with the rotation axis of the connector 2 to prevent the fabric roll tube 3 from shaking during rotation.

[0054] like Figure 2 As shown, in one implementation, the drive assembly 4 includes a drive bracket 401 and a motor 402. The drive bracket 401 is mounted on the frame 1, and a connection space 403 is formed between the drive bracket 401 and the frame 1. The connector 2 extends at least partially into the connection space 403.

[0055] The drive bracket 401 isolates the part where the motor 402 is connected to the shaft 204 of the connector 2, preventing the fabric from getting stuck at the connection between the motor 402 and the shaft 204, thus improving the safety of the fabric winding.

[0056] Specifically, the drive assembly 4 also includes a transmission member 404, which is connected to the motor 402 and the connector 2 respectively. At least a portion of the transmission member 404 is located in the connection space 403, thereby facilitating the connection between the transmission member 404 and the rotating shaft 204 and preventing the fabric from getting stuck at the connection between the transmission member 404 and the rotating shaft 204.

[0057] It should be noted that the transmission component 404 can be a gear pair or a belt or pulley assembly, and this application does not limit the specific structure of the transmission component 404.

[0058] like Figure 1 and Figure 2 As shown, in one implementation, the drive bracket 401 includes a mounting plate 4011 and four connecting columns 4012. The mounting plate 4011 is mounted on the frame 1 through the connecting columns 4012, and a connection space 403 is formed between the mounting plate 4011 and the frame 1.

[0059] As one implementation, the drive bracket 401 also includes a first bearing 4013, which is mounted on the mounting plate 4011.

[0060] The frame 1 includes a second bearing 102, which is mounted on the frame plate 101.

[0061] The first bearing 4013 and the second bearing 102 are coaxially arranged, and both the first bearing 4013 and the second bearing 102 are connected to the rotating shaft portion 204 of the connector 2, so that the rotating shaft portion 204 is rotatably connected to the mounting plate 4011 and the frame plate 101, thereby improving the installation stability of the connector 2.

[0062] As one implementation, the drive assembly 4 also includes a motor frame 405, through which the motor 402 is mounted on the frame plate 101 so that the motor 402 can be connected to the transmission component 404.

[0063] As one implementation, the computerized flat knitting machine's fabric winding device also includes a sensor 6, which is installed on the frame 1 along a first direction and is spaced apart from the fabric winding tube 3. The sensor 6 is used to detect the thickness of the fabric wound on the fabric winding tube 3.

[0064] Specifically, sensor 6 can be an infrared sensor. As the fabric roll tube 3 rotates, the thickness of the fabric wound onto the roll tube 3 gradually increases. When the fabric blocks the infrared light of sensor 6, sensor 6 is triggered, prompting the operator to wind the fabric to the preset thickness.

[0065] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
