Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine technology, specifically to a warp feeding device for a warp knitting machine. Background Technology

[0002] A warp knitting machine uses one or more sets of parallel yarns fed into all the working needles of the machine in the warp direction to form loops and create knitted fabric. This method is called warp knitting, and the machine that completes this type of warp knitting is called a warp knitting machine. Existing warp knitting machines generally use a coiled head for feeding warp.

[0003] For example, our company previously disclosed a novel disc brake device in Chinese patent application CN222795881U, which includes a frame and a disc head. The disc head is mounted on the frame via a rotating shaft. The frame includes a base and a side frame. The disc head is rotatably connected to the rotating shaft via a bearing. A first transmission gear is integrally formed on one side of the disc head, and a second transmission gear meshes below the first transmission gear. The second transmission gear is fixedly connected to a gear shaft. At the same time, a bearing mounting hole is provided on the side frame on the right side of the frame corresponding to the gear shaft. The gear shaft passes through the bearing mounting hole and is rotatably connected to the bearing mounting hole via a bearing. The right end of the gear shaft passes through the bearing mounting hole and is fixedly connected to a brake wheel.

[0004] In the above technical solution, the contact between the brake pads and the brake wheel is controlled by a stepper motor, which can freely control the deceleration effect of the pan head, thereby controlling the output speed of the pan head.

[0005] However, in actual use, it has been found that the pan heads used often have different axial lengths, and the above technical solutions need to be adapted to pan heads of the same specification, thus limiting their applicability. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a warp feeding device for a warp knitting machine that can adapt to warp heads of different axial lengths and expand its application range.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a warp feeding device for a warp knitting machine, comprising a frame and a warp head. The frame has two symmetrical connecting arms on its inner side, and a fixed sleeve and a movable sleeve are respectively provided on opposite sides of the connecting arms. The warp head has sleeves on both sides, and each sleeve has a hole for inserting the fixed sleeve or the movable sleeve. The movable sleeve can move closer to or further away from the fixed sleeve to adapt to warp heads of different axial lengths. The frame is provided with a braking mechanism that moves with the movable sleeve, and the braking mechanism is used to adjust the rotation speed of the warp head.

[0008] The present invention is further configured to include an adjusting screw, wherein the end of the connecting arm for connecting the movable sleeve is provided with a sleeve, the sleeve is provided with a first threaded hole, the adjusting screw is provided in the first threaded hole, and the two can form a threaded engagement.

[0009] The present invention is further configured such that: the adjusting screw has a connector at the end facing the pan head, a connecting plate is fitted around the outer periphery of the connector, the movable sleeve is integrally connected to the connecting plate, the connecting plate can rotate around the axis of the connector, a positioning rod parallel to the adjusting screw is provided in the frame, a connecting flange is provided around the outer periphery of the connecting plate, one end of the connecting flange is fitted around the outer periphery of the positioning rod, and a sliding fit is formed between the two.

[0010] The present invention is further configured such that: the braking mechanism includes a bracket plate integrally connected to the connecting plate and a lifting screw, the bracket plate is provided with a guide cylinder, the guide cylinder is provided with a second threaded hole, the lifting screw is disposed in the second threaded hole and can form a threaded engagement between the two, the lifting screw is provided with a connecting frame at one end facing the sleeve, the connecting frame is provided with a brake block, and the brake block is adjusted by lifting to adjust the resistance applied when the disc head rotates.

[0011] The present invention is further configured such that: the connecting frame is centrally fitted around the outer periphery of the end of the lifting screw and can rotate around the axis of the lifting screw; a guide rod is fixed at the top of the connecting frame; a guide hole is provided on the support plate opposite to the guide rod; and the guide rod can form a sliding fit with the guide hole.

[0012] The present invention is further configured such that: a connecting rod is fixed on the inner side of the connecting frame; one end of the brake block is fitted around the outer periphery of the connecting rod and can rotate around the axis of the connecting rod; a torsion spring is fitted around the outer periphery of the connecting rod; and the two ends of the torsion spring are respectively connected to the outer wall of the brake block and the inner wall of the connecting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Because fixed sleeves and movable sleeves are respectively provided on opposite sides of the connecting arms on both sides, and sleeves for the fixed sleeves or movable sleeves to be inserted on both sides of the pan head, the movable sleeves can move closer to or further away from the fixed sleeves to adapt to pan heads of different axial lengths, thereby expanding the range of applications.

Detailed Implementation

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figures 1 to 5As shown, this utility model discloses a warp feeding device for a warp knitting machine, including a frame 1 and a warp head 2. The frame 1 has two symmetrical connecting arms 3 on its inner side. The two sides of the connecting arms 3 are respectively provided with a fixed sleeve rod 4 and a movable sleeve rod 5. The two sides of the warp head 2 are provided with sleeves 21. The sleeves 21 are provided with sleeve holes for the fixed sleeve rod 4 or the movable sleeve rod 5 to be inserted. The movable sleeve rod 5 can move closer to or further away from the fixed sleeve rod 4 to adapt to warp heads 2 with different axial lengths, thereby expanding the scope of application. Furthermore, the frame 1 is provided with a braking mechanism that moves with the movable sleeve rod 5. In this way, the braking mechanism can adjust its own position according to the warp head 2 with different axial lengths, thereby adjusting the rotation speed of the warp head 2 with different axial lengths.

[0024] In this embodiment, the structure that drives the movable sleeve 5 to move specifically includes an adjusting screw 6. An integrally formed sleeve 7 is provided at the end of the connecting arm 3 used to connect the movable sleeve 5. A first threaded hole is provided in the sleeve 7. The adjusting screw 6 is provided in the first threaded hole and can form a threaded engagement between the two. Thus, by rotating the adjusting screw 6, the movable sleeve 5 can be driven to move.

[0025] Specifically, the connection structure between the movable sleeve 5 and the adjusting screw 6 is as follows: A connector 61 is integrally formed at the end of the adjusting screw 6 facing the pan head 2. A connecting plate 8 is fitted around the outer periphery of the connector 61. The movable sleeve 5 is integrally connected to the connecting plate 8. The connecting plate 8 can rotate around the axis of the connector 61. Hoops 200 are fitted on both sides of the connecting plate 8 around the outer periphery of the connector 61 to axially limit the connecting plate 8 and prevent it from detaching from the connector 61. Furthermore, a positioning rod 10 parallel to the adjusting screw 6 is provided inside the frame 1. A connecting flange 81 is welded and fixed to the outer periphery of the connecting plate 8. One end of the connecting flange 81 is fitted onto the outer periphery of the positioning rod 10, forming a sliding fit between the two. Thus, when the adjusting screw 6 is rotated to drive the moving sleeve rod 5 to move, the brake mechanism set on the connecting plate 8 can be prevented from rotating with the adjustment screw 6 due to the guiding effect formed between the rotatable connecting plate 8 and the positioning rod 10 and the connecting flange 81. This ensures that the brake mechanism is stationary when moving with the moving sleeve rod 5, thereby facilitating the subsequent adjustment of the rotation speed of the disc head 2 by the brake mechanism.

[0026] In this embodiment, the specific structure of the braking mechanism includes a bracket plate 91 and a lifting screw 92 integrally connected to the connecting disc 8. The bracket plate 91 is provided with a guide cylinder 911, and the guide cylinder 911 is provided with a second threaded hole. The lifting screw 92 is disposed in the second threaded hole and can form a threaded engagement between the two. The end of the lifting screw 92 facing the sleeve 21 is provided with a connecting frame 93, and the connecting frame 93 is provided with a brake block 94. By rotating the lifting screw 92, the brake block 94 can be driven to rise and fall, so that the brake block 94 can adjust the resistance applied when the disc head 2 rotates by rising and falling.

[0027] Specifically, the structure of the brake block 94, which adjusts the resistance applied when the pan head 2 rotates by raising and lowering, is as follows: a connecting rod 96 is fixed inside the connecting frame 93; one end of the brake block 94 is fitted around the outer periphery of the connecting rod 96 and can rotate around the axis of the connecting rod 96; a torsion spring 97 is fitted around the outer periphery of the connecting rod 96; the two ends of the torsion spring 97 are respectively connected to the outer wall of the brake block 94 and the inner wall of the connecting frame 93. Thus, when the lifting screw 92 drives the brake block 94 to descend, the brake block 94 can gradually contact the sleeve 21 on one side of the pan head 2, thereby gradually squeezing the torsion spring 97. By applying different degrees of compression to the torsion spring 97, different levels of resistance can be applied when the pan head 2 rotates, thus adjusting the rotation speed of the pan head 2 and enabling different speeds of line feeding.

[0028] In this embodiment, the connecting frame 93 is centrally fitted around the outer periphery of the end of the lifting screw 92 and can rotate around the axis of the lifting screw 92. In order to prevent the connecting frame 93 from falling off the lifting screw 92, after the connecting frame 93 is centrally fitted around the outer periphery of the end of the lifting screw 92, the end cap 100 is pressed into the end of this side to limit the axial movement of the connecting frame 93. In addition, a guide rod 95 is fixed on the top of the connecting frame 93, and a guide hole 912 opposite to the guide rod 95 is provided on the bracket plate 91. The guide rod 95 can form a sliding fit with the guide hole 912. In this way, the connecting frame 93 can be rotated with the lifting screw 92 under the guidance of the rotatable connecting frame 93 and the guide hole 912 and the guide rod 95, thereby ensuring the stability of the brake block 94 when applying resistance to the sleeve 21.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
