Description

Technical Field

[0001] This utility model relates to the field of circular loom technology, and in particular to an automatic tension threading plate for a circular loom. Background Technology

[0002] The tension threading plate is located on one side of the warp beam. Several tension rods are installed on the tension threading plate. One end of the tension rod is hinged to the threading plate, and the other end is provided with a threading hole. When the warp thread passes through the threading hole, the tension rod pulls the passing warp thread taut due to its own weight. However, due to its own weight, the tension rod always hangs down, so when threading or splicing warp threads, it is necessary to hold the tension rod, which is somewhat inconvenient. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides an automatic tension threading plate for the yarn frame of a circular loom. It can lock the raised tension rod to prevent it from swinging and falling on its own. After the threading is completed, it drives the locking part to disengage from the tensioning member, thus achieving the tensioning effect. It is more convenient to connect and thread the yarn and does not affect its normal gravity fall.

[0004] This utility model discloses an automatic tension threading plate for a circular loom, comprising an assembly frame, a mounting shaft horizontally mounted on the assembly frame, a plurality of mounting seats spaced apart on the mounting shaft, and a tensioning rod between two adjacent mounting seats. The tensioning rod includes a hinged portion hinged to the mounting shaft and an outwardly extending movable portion, the movable portion having a threading hole for the warp yarn to pass through. The assembly frame also has a thread-passing hole located in front of the threading hole. The tensioning rod is characterized by having a locking portion and an expansion member on the mounting seats. When the tensioning rod is driven to swing upward, the locking portion can rotate to engage with the expansion member, thereby tightening the tensioning rod.

[0005] A further feature of this invention is as follows: the tensioning element is a spring sheet, the locking part is an extension arm, the movable part is located on one side of the hinge part, the extension arm is located on the opposite side of the hinge part, the spring sheet is provided with a positioning block, the extension arm is provided with a positioning groove that matches the positioning block, and the positioning block is located on the movement trajectory of the lower swing of the positioning groove.

[0006] A further feature of this invention is that a counterweight is provided at one end of the movable part where a threading hole is provided, the threading hole being located on the counterweight, and the counterweight being made of ceramic.

[0007] A further feature of this invention is that the mounting shaft and tensioning rod are made of conductive material, and a conductive rod is provided on the swing trajectory below the movable part on the assembly frame. When the warp wire breaks, the movable part can swing to contact the conductive rod to achieve electrical connection.

[0008] A further feature of this invention is that the bottom of the movable part is bent and tilted upward to form a lifting section, and the counterweight is located at the top of the lifting section.

[0009] Using the above technical solution, when the tensioning rod is raised to a certain angle, the locking part swings to the position of the tensioning member. The tensioning member limits the tensioning rod to prevent it from rotating on its own. After the threading is completed, the tensioning rod is rotated by external force, thereby causing the locking part to disengage from the tensioning member, thus achieving the tensioning effect on the warp. This makes it more convenient to connect and thread the warp and does not affect its normal gravity descent. Attached Figure Description

[0015] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0016] In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and 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 this utility model.

[0017] This utility model discloses an automatic tension threading plate for a circular loom, comprising an assembly frame 1, a mounting shaft 2 horizontally mounted on the assembly frame 1, and a plurality of mounting seats 3 spaced apart on the mounting shaft 2. A tensioning rod 4 is provided between two adjacent mounting seats 3. The tensioning rod 4 includes a hinge portion 41 hinged to the mounting shaft and a movable portion 42 extending outside the mounting seats 3. The movable portion 42 is provided with a threading hole 5 for the warp yarn to pass through. A threading hole 6 is also provided on the assembly frame 1 in front of the threading hole 5. In an embodiment of this utility model, the tensioning rod 4 is further provided with... The mounting base 3 is also provided with a tensioning member 7 on the snap-fit ​​part 43. When the tensioning rod 4 is driven to swing upward, the snap-fit ​​part 43 can be rotated to cooperate with the tensioning member 7 to achieve tensioning of the tensioning rod 4. When the tensioning rod 4 is raised to a certain angle, the snap-fit ​​part 43 swings to the position of the tensioning member 7. The tensioning member 7 limits the tensioning rod 4 to prevent it from rotating on its own. After the threading is completed, the tensioning rod 4 is rotated by external force, thereby causing the snap-fit ​​part 43 to disengage from the tensioning member 7, thus achieving the tensioning effect on the warp thread. This makes it more convenient to connect and thread the wire and does not affect its normal gravity descent.

[0018] The tensioning element 7 is a spring sheet, the locking part 43 is an extension arm, the movable part 42 is located on one side of the hinge part 41, and the extension arm is located on the opposite side of the hinge part 41. The spring sheet is provided with a positioning block 71, and the extension arm is provided with a positioning groove 431 that matches the positioning block 71. The positioning block 71 is located on the movement trajectory of the lower swing of the positioning groove 431. The spring sheet can be relatively elastically deformed, which facilitates the positioning block 71 to enter and exit the positioning groove 431. The use of the positioning block 71 and the positioning groove 431 can increase stability and the structure is relatively simple. The tensioning rod 4 can be rotated by external force. Of course, the tensioning element 7 can also be an elastic pad or a top pin, etc.

[0019] A counterweight 8 is provided at one end of the movable part 42 with a threading hole 5. The threading hole 5 is located on the counterweight 8, which is made of ceramic. The counterweight 8 is preferably a detachable and replaceable ceramic cap because ceramic is relatively smooth, which can prevent the warp threads from fraying. It can also be replaced periodically without replacing the entire tension rod 4, thus reducing maintenance costs. The counterweight 8 can increase the weight at the end of the movable part 42. While increasing the tension, it can also improve the swing sensitivity of the movable part 42. Because the mounting base 3 is located on opposite sides of the tension rod 4 and has limiting surfaces, it will prevent the rod from swaying left and right. Therefore, it has some friction. It is necessary to overcome the friction to flip it downwards better. Preferably, the front side of the ceramic cap is provided with a relief groove.

[0020] The mounting shaft 2 and tensioning rod 4 are made of conductive material. A conductive rod 9 is provided on the swing track below the movable part 42 on the assembly frame 1. When the warp wire breaks, the movable part 42 can swing to contact the conductive rod 9 to achieve electrical connection. An alarm, such as an indicator light or a buzzer alarm, can be installed on the assembly frame 1. The alarm can be triggered when the movable part 42 contacts the conductive rod 9.

[0021] The bottom of the movable part 42 is bent and tilted upward to form a lifting section 421. The counterweight 8 is located at the top of the lifting section 421, which can increase the counterweight at the end of the movable part 42 and raise the height of the counterweight 8, making it easier for the warp threads to pass through the threading hole 5.
