Description

Technical Field

[0001] This utility model relates to the field of knitting equipment technology, and more specifically to a double-sided jacquard knitting machine. Background Technology

[0002] A double-sided jacquard knitting machine, application number 202321654030.5, includes a fixed base. A fixed block is rotatably connected to the top of the fixed base. Support side plates are fixedly connected to both sides of the fixed block. A set of protective side plates is installed on the inner wall of the connecting plate. A take-up roller is fixedly connected to the inner side of the protective side plates. A set of limiting blocks is slidably connected to the surface of the take-up roller. Two sets of limiting rods are fixedly connected to the surface of the limiting blocks. A compression spring is sleeved on the surface of the take-up roller. This invention utilizes the combined use of protective side plates, the take-up roller, the limiting rods, and the compression spring. The limiting blocks move towards the center under the reaction force of the compression spring, thereby limiting the fabric take-up range on the surface of the take-up roller. Simultaneously, the limiting blocks can be adjusted according to different sizes of fabric.

[0003] However, while it can adjust the winding area to ensure a neat winding effect in the lateral direction, it cannot avoid wrinkles that may occur during the winding process of the fabric, and still cannot completely guarantee a neat winding effect of the fabric. Utility Model Content

[0004] This utility model provides a double-sided jacquard knitting machine, which has the advantage of ensuring that the fabric is neatly rolled up and avoiding wrinkles.

[0005] A double-sided jacquard knitting machine includes a fixed frame, on which mounting plates A and B are connected. A take-up roller is rotatably connected between mounting plates A and B. An auxiliary plate is slidably connected to the take-up roller. An L-shaped frame is connected to mounting plate A. A pressure rod is slidably connected to the L-shaped frame. A cylindrical rod is fixedly connected to the pressure rod. A second compression spring is fixedly connected between the pressure rod and the L-shaped frame. A rectangular plate is fixedly connected to the pressure rod. A second compression spring is fixedly connected between the rectangular plate and the L-shaped frame. A drive rod is slidably connected to the L-shaped frame. The drive rod can contact the cylindrical rod.

[0006] Both mounting plate A and mounting plate B have multiple threaded holes. Mounting plate A and mounting plate B are detachably connected to the fixed frame by screwing bolts into the multiple threaded holes. The L-shaped frame is detachably connected to mounting plate A by bolts.

[0007] It also includes a first compression spring fixed between the mounting plate B and the auxiliary plate.

[0008] The pressure bar has a rounded chamfer.

[0009] It also includes a lead screw connected to the L-shaped frame, which can rotate about a virtual axis, and the lead screw is threadedly connected to the drive rod.

[0010] It also includes a servo motor fixed to an L-shaped frame, with the output shaft of the servo motor fixed to a lead screw. Attached Figure Description

[0016] Figure 6 This is a structural diagram of the fixing frame. Detailed Implementation

[0017] like Figure 1-6 As shown:

[0018] The system includes a fixed frame 401, on which mounting plates A107 and B108 are connected. A take-up roller 101 is rotatably connected between mounting plates A107 and B108. An auxiliary plate 104 is slidably connected to the take-up roller 101. An L-shaped frame 109 is connected to mounting plate A107. A pressure rod 301 is slidably connected to the L-shaped frame 109. A cylindrical rod 304 is fixed to the pressure rod 301. A second compression spring 303 is fixed between the pressure rod 301 and the L-shaped frame 109. A rectangular plate 305 is fixed to the pressure rod 301. The second compression spring 303 is fixed between the rectangular plate 305 and the L-shaped frame 109. A drive rod 203 is slidably connected to the L-shaped frame 109. The drive rod 203 can contact the cylindrical rod 304. A drive motor capable of driving the take-up roller 101 to rotate is fixed to mounting plate A107.

[0019] The fixing frame 401 is connected to the fabric take-up position of the knitting machine by tightening bolts. During use, the produced double-sided jacquard fabric is bonded to the take-up roller 101. Then, the take-up roller 101 is operated to rotate between the mounting plate A107 and the mounting plate B108. The rotating take-up roller 101 continuously takes up the fabric to achieve an automatic take-up effect. During the take-up process, the auxiliary plate 104 will always be against one side of the fabric, thereby restricting the take-up position of the fabric in conjunction with the mounting plate A107, so that the fabric can be neatly taken up on the take-up roller 101.

[0020] After one end of the woven fabric is attached to the take-up roller 101, the operating drive rod 203 slides on the L-shaped frame 109 towards the take-up roller 101. During this process, the cylindrical rod 304 is subjected to the elastic force of the second compression spring 303 and thus always presses against the take-up roller 101 until the pressure rod 301 presses against the surface of the take-up roller 101. Then, the subsequent winding operation is carried out. During the subsequent winding operation, the pressure rod 301 will always be pressed against the take-up roller by the elastic force of the second compression spring 303. On roller 101, as the winding thickness gradually increases, the pressure bar 301 will adaptively slide on the L-shaped frame 109 overcoming the elastic force of the second pressure spring 303, so that the pressure bar 301 can always be pressed against the winding fabric, thereby flattening the winding fabric and ensuring that the wrinkles that occur in the fabric during the winding process can be flattened in time by the pressure bar 301, thereby further improving the winding effect and achieving the effect of ensuring that the fabric is neatly wound and avoiding wrinkles.

[0021] like Figure 2-3 As shown:

[0022] Both mounting plate A107 and mounting plate B108 are provided with multiple threaded holes 103. Mounting plate A107 and mounting plate B108 are detachably connected to the fixing frame 401 by screwing bolts into the multiple threaded holes 103. L-shaped frame 109 is detachably connected to mounting plate A107 by bolts.

[0023] After winding is completed, mounting plates A107 and B108 can be removed from the fixed frame 401 by loosening the bolts, and a new winding roller 101 can be replaced for subsequent winding work. After completing one winding operation, the L-shaped frame 109 can be removed from the mounting plate A107 by loosening the bolts, and the structure on the L-shaped frame 109 can be reused, bringing convenience to actual use.

[0024] like Figure 3 As shown:

[0025] It also includes a first compression spring 102 fixed between the mounting plate B108 and the auxiliary plate 104.

[0026] The first compression spring 102 can provide elasticity to the auxiliary plate 104, so that the auxiliary plate 104 can abut against the side of the fabric winding position, thereby providing a stable guarantee for the effect of the auxiliary plate 104 in restricting the winding area.

[0027] like Figure 5 As shown:

[0028] The pressure rod 301 is provided with a rounded chamfer 302.

[0029] In actual use, the rounded chamfer 302 allows the pressure bar 301 to slide smoothly into contact with the take-up roller 101. When the pressure bar 301 moves to the position of contact with the auxiliary plate 104, the rounded chamfer 302 can smoothly move the auxiliary plate 104 to slide slightly, which facilitates the pressure bar 301 to smoothly enter the position of contact with the take-up roller 101 and allows the pressure bar 301 to fully contact the area of ​​the fabric to be taken up, ensuring the subsequent flattening effect.

[0030] like Figure 4 As shown:

[0031] It also includes a lead screw 202 connected to the L-shaped frame 109, which can rotate about a virtual axis and is threadedly connected to the drive rod 203.

[0032] When it is necessary to rotate the drive rod 203, the lead screw 202 is rotated, and the rotating lead screw 202 drives the drive rod 203 to slide on the L-shaped frame 109. This causes the drive rod 203 to slide along the L-shaped frame 109 under the limit of the L-shaped frame 109, thus completing the subsequent sliding effect of the drive pressure rod 301.

[0033] like Figure 4 As shown:

[0034] It also includes a servo motor 201 fixedly connected to the L-shaped frame 109, and the output shaft of the servo motor 201 is fixedly connected to the lead screw 202.

[0035] When it is necessary to rotate the lead screw 202, the servo motor 201 is started, causing the output shaft of the servo motor 201 to drive the lead screw 202 to rotate, which in turn causes the lead screw 202 to drive the drive rod 203 to slide, thus completing the subsequent driving effect.

[0036] like Figure 4 As shown:

[0037] It also includes a handle 106 fixed to the L-shaped frame 109.

[0038] The handle 106 allows workers to lift the entire device by holding the handle 106, which facilitates subsequent installation or disassembly.

[0039] like Figure 4 As shown:

[0040] The handle 106 is wrapped with a rubber layer.

[0041] The rubber layer can wrap and protect the handle 106 to prevent workers' hands from being scratched.

[0042] like Figure 6 As shown:

[0043] It also includes a positioning arc plate 403 fixed to the fixed frame 401.

[0044] The positioning arc plate 403 allows the mounting plate A107 to be placed on the positioning arc plate 403 when installing the mounting plate A107 and the mounting plate B108, thereby accurately positioning the mounting plate A107 and facilitating subsequent installation work.

[0045] like Figure 6 As shown:

[0046] It also includes a positioning rod 402 fixed to the fixing frame 401.

[0047] The positioning rod 402 allows the L-shaped bracket 109 to be placed on the positioning rod 402 during installation, further facilitating the precise positioning of the mounting plate A107 and making subsequent installation easier.
