Abstract
Description
Technical Field
[0001] This utility model relates to the field of rapier head technology, specifically a flexible weft-jointing rapier head. Background Technology
[0002] The rapier head is a key component of the rapier loom for completing the weft insertion task. It works in conjunction with the rapier to draw the weft yarn from the weft feeder through the shed.
[0003] In actual use, the position of the hook groove of the existing rapier head is fixed. However, different models of hook grooves are required on different looms, which makes it impossible to adjust the existing rapier head for different equipment. At the same time, the existing rapier head is extremely difficult to disassemble, which leads to a lot of time being spent when the rapier head needs to be replaced. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a flexible weft splice rapier head, which has the advantages of being adjustable and easy to disassemble, thus solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a flexible weft-jointing rapier head, including a mounting base, a rapier body slidably connected to the inner wall of the mounting base, a scale fixedly installed on the outer wall of the rapier body, a pull plate provided at the top of the mounting base, a locking post and a pull rod fixedly installed at the bottom of the pull plate, an extension ring fixedly installed at the bottom of the pull rod, a spring one provided on the inner wall of the mounting base, a limit post fixedly installed on the inner wall of the mounting base, a threaded post rotatably connected to the inner wall of the rapier body, a sliding plate slidably connected to the inner wall of the rapier body, a hook groove fixedly installed on the outer wall of the sliding plate, a rotating post fixedly installed at the top of the threaded post, a horizontal plate slidably connected to the inner wall of the rotating post, a pressure plate fixedly installed on the outer wall of the horizontal plate, a connecting plate fixedly installed at the bottom of the horizontal plate, a limit rod fixedly installed on the inner wall of the rotating post, a friction plate fixedly installed on the outer wall of the connecting plate, and a spring two provided on the inner wall of the rotating post.
[0006] As a preferred technical solution of this utility model: the friction plate is located outside the rotating column, and the cross plate is in contact with the inner wall of the sword shaft body.
[0007] As a preferred technical solution of this utility model: the limiting rod passes through the connection between the horizontal plate and the connecting plate, and the limiting rod is slidably connected to the connection between the horizontal plate and the connecting plate.
[0008] As a preferred technical solution of this utility model: the threaded column passes through the sliding plate, and the threaded column and the sliding plate are connected by threads.
[0009] As a preferred technical solution of this utility model: the extension ring is located on the inner wall of the mounting base, and the extension ring is in contact with the inner wall of the mounting base.
[0010] As a preferred technical solution of this utility model: the diameter of the locking pin is adapted to the top inner wall of the sword shaft body, and the diameter of the limiting pin is adapted to the outer inner wall of the sword shaft body.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This flexible weft-jointing rapier head, by pressing the pressure plate, causes the pressure plate to move the cross plate and connecting plate, which in turn causes the connecting plate to move the friction plate. As a result, the friction plate is no longer in contact with the inner wall of the rapier body. At this time, the rotating column can rotate. By rotating the rotating column, the rotating column causes the threaded column to rotate, which in turn causes the threaded column to move the sliding plate, which in turn causes the hook groove to move. The position of the hook groove can be adjusted by observing its position outside the scale.
[0013] 2. The flexible weft-jointing rapier head, by pulling the pulling plate upward, causes the bottom pull rod and extension ring to move upward, and at the same time, the locking pin moves upward. At this time, the spring is compressed, and the locking pin separates from the top inner wall of the rapier body, thus eliminating the fixing relationship of the rapier body. At this time, the rapier body is pulled outward, thus removing the rapier body from the outside of the limiting pin, and thus the rapier body is taken out. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1 - Figure 5 A flexible weft-jointed rapier head includes a mounting base 1, a rapier body 2 slidably connected to the inner wall of the mounting base 1, a scale 3 fixedly installed on the outer wall of the rapier body 2, a pull plate 4 at the top of the mounting base 1, a locking pin 5 and a pull rod 7 fixedly installed at the bottom of the pull plate 4, an extension ring 8 fixedly installed at the bottom of the pull rod 7, a spring 9 on the inner wall of the mounting base 1, a limit pin 6 fixedly installed on the inner wall of the mounting base 1, and a threaded pin 10 rotatably connected to the inner wall of the rapier body 2. The inner wall of 2 is slidably connected to a sliding plate 11, the outer wall of the sliding plate 11 is fixedly installed with a hook groove 12, the top of the threaded column 10 is fixedly installed with a rotating column 13, the inner wall of the rotating column 13 is slidably connected to a horizontal plate 15, the outer wall of the horizontal plate 15 is fixedly installed with a pressure plate 14, the bottom of the horizontal plate 15 is fixedly installed with a connecting plate 16, the inner wall of the rotating column 13 is fixedly installed with a limit rod 17, the outer wall of the connecting plate 16 is fixedly installed with a friction plate 19, and the inner wall of the rotating column 13 is provided with a spring 18.
[0022] In the above structure, the scale 3 is located at the bottom of the hook groove 12, so that when the hook groove 12 moves, it moves outside the scale 3. By observing the position of the hook groove 12 outside the scale 3, the height of the hook groove 12 can be adjusted, thereby preventing the hook groove 12 from being too high or too low.
[0023] In a preferred embodiment: the friction plate 19 is located outside the rotating column 13, and the cross plate 15 is in contact with the inner wall of the sword body 2;
[0024] In the above structure, the elasticity of the second spring 18 pushes the connecting plate 16, which in turn causes the connecting plate 16 to drive the friction plate 19 to move outward, so that the connecting plate 16 fits against the inner wall of the sword shaft body 2. At the same time, the friction between the friction plate 19 and the sword shaft body 2 is increased by the friction plate 19, so that the friction plate 19 cannot rotate, and the rotating column 13 and the threaded column 10 will not rotate on their own.
[0025] In a preferred embodiment: the limiting rod 17 passes through the connection between the horizontal plate 15 and the connecting plate 16, and the limiting rod 17 is slidably connected to the connection between the horizontal plate 15 and the connecting plate 16.
[0026] In the above structure, the connection between the horizontal plate 15 and the connecting plate 16 is limited by the limiting rod 17, thereby limiting the horizontal plate 15 and the connecting plate 16. As a result, when the horizontal plate 15 and the connecting plate 16 move, their connection can only slide on the outer wall of the limiting rod 17, thus preventing the horizontal plate 15 and the connecting plate 16 from tilting when moving.
[0027] In a preferred embodiment: the threaded post 10 passes through the sliding plate 11, and the threaded post 10 and the sliding plate 11 are threadedly connected;
[0028] In the above structure, by rotating the rotating column 13, the rotating column 13 drives the threaded column 10 to rotate, which in turn causes the threaded column 10 to move through the threaded connection with the sliding plate 11, which in turn causes the sliding plate 11 to rotate, making the position of the hook groove 12 adjustable.
[0029] In a preferred embodiment: the extension ring 8 is located on the inner wall of the mounting base 1, and the extension ring 8 is in contact with the inner wall of the mounting base 1;
[0030] In the above structure, the extension ring 8 is limited when it moves by fitting with the inner wall of the mounting base 1, so that the extension ring 8 will not tilt when it moves, and thus the top spring 9 and the pulling plate 4 will not tilt when they move.
[0031] In a preferred embodiment: the diameter of the locking pin 5 is adapted to the top inner wall of the sword shaft body 2, and the diameter of the limiting pin 6 is adapted to the outer inner wall of the sword shaft body 2.
[0032] In the above structure, by fitting the outer inner wall of the sword shaft body 2 onto the outer wall of the limiting post 6, and pushing the sword shaft body 2 inward to the innermost side, the limiting post 6 limits the sword shaft body 2, preventing the sword shaft body 2 from moving up and down. At the same time, the locking post 5 fixes the top inner wall of the sword shaft body 2, preventing the top inner wall of the sword shaft body 2 from moving, thus preventing the sword shaft body 2 from moving.
[0033] Working principle: When using this equipment, it needs to be assembled. By pulling the pull plate 4 upward, the outer inner wall of the sword rod body 2 is fitted onto the outer wall of the limiting post 6, and the sword rod body 2 is pushed inward to the innermost side, thereby limiting the sword rod body 2 to the limit post 6, preventing the sword rod body 2 from moving up and down. At this time, the pull plate 4 is released, and the spring 9 rebounds, pushing the extension ring 8 and the spring 9 downward. This causes the spring 9 to drive the pull plate 4 downward, so that the locking post 5 at the bottom of the pull plate 4 enters the top inner wall of the sword rod body 2, fixing the sword rod body 2 to the inner wall of the mounting base 1. At this time, according to the installation equipment, the hook groove 1 is aligned. The position of 2 is adjusted by pressing the pressure plate 14, which causes the pressure plate 14 to move the horizontal plate 15 and the connecting plate 16, which in turn causes the connecting plate 16 to move the friction plate 19, so that the friction plate 19 is no longer in contact with the inner wall of the sword body 2. At this time, the rotating column 13 can rotate. By rotating the rotating column 13, the rotating column 13 causes the threaded column 10 to rotate, which causes the threaded column 10 to move the sliding plate 11 through the threaded connection with the sliding plate 11, which in turn causes the sliding plate 11 to move the hook groove 12, so that the position of the hook groove 12 can be adjusted. The position of the hook groove 12 is adjusted by observing the position of the hook groove 12 outside the scale 3.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
