DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0029] The specific embodiments of the present utility model are described below with reference to the accompanying drawings.

[0030] like Figure 1-11The shuttle and circular loom shown in the figure include a shuttle frame 1, on which two spaced-apart tube seats 2 are rotatably mounted. The two tube seats 2 are coaxially mounted and a weft bobbin 3 is clamped between them. A bearing 17 is disposed in each tube seat 2. The bearing 17 is directly or indirectly fixed to the shuttle frame 1. The tube seat 2 and the bearing 17 are rotatably engaged. The two ends of the weft bobbin 3 are respectively sleeved outside the two tube seats 2, or the two ends of the weft bobbin 3 are respectively inserted into the two tube seats 2, or one end of the weft bobbin 3 is inserted into one of the tube seats 2 and the other end is sleeved outside the other tube seat 2; either end of the weft bobbin 3 (left end or right end or both ends, that is, to At least one end, in this embodiment, the preferred method is that elastic parts 4 are provided between the two tube seats 2 and the weft tube 3) and the corresponding tube seats 2 are matched and an elastic part 4 is provided between the two, and the elastic part 4 is limited to the outer wall of the weft tube 3 and the inner wall of the tube seat 2 to achieve gap compensation at the matching point; or, the elastic part 4 is limited to the inner wall of the weft tube 3 and the outer wall of the tube seat 2 to achieve gap compensation at the matching point. In this embodiment, whether the weft tube 3 is sleeved on the outer wall of the tube seat 2 or the weft tube 3 is inserted into the tube seat 2, a step 15 needs to be provided outside the weft tube 3 or a step 15 needs to be provided outside the tube seat 2 to ensure that the two end parts of the weft tube 3 are matched with the tube seat 2.

[0031] The weft tube 3 can be sleeved on the outside of the tube seat 2 or inserted into the tube seat 2. No matter which method is used, the gap between the inner and outer walls can be compensated by the elastic part 4 at the joint between the two to make up for the error in the parts processing accuracy. In the process of clamping the weft tube 3 by the two tube seats 2, the structure based on the elastic part 4 can gradually tighten the tube seat 2 and the weft tube 3 to form a locking positioning for the weft tube 3, avoiding shaking and jamming when the weft tube 3 is released and weaving, thereby improving the weaving effect and increasing the service life of the weft tube 3 and the tube seat 2.

[0032] This application has the following three embodiments: Example

[0033] like Figure 4 、 5 As shown, the elastic member 4 is an O-ring 5 , and the O-ring 5 is sleeved on the outer wall of the weft cylinder 3 ; or, the O-ring 5 is sleeved on the outer wall of the tube seat 2 .

[0034] The pipe seat 2 is provided with an annular groove 6 for installing the O-ring 5; or, the weft cylinder 3 is provided with an annular groove 6 for installing the O-ring 5.

[0035] Working principle: The end of the weft cylinder 3 can be sleeved on the outside of the tube seat 2, and the inner ring of the O-ring 5 is sleeved in the annular groove 6. The outer ring of the O-ring 5 contacts the inner wall of the weft cylinder 3 to form a locking position for the weft cylinder 3. The O-ring 5 plays a role in shock absorption and anti-slip. Specifically, the weft cylinder 3 and the tube seat 2 can rotate synchronously. When rotating at high speed, the two will not rotate relative to each other, avoiding slippage and causing wear between the two components, which will delay the service life. The outer diameter of the O-ring 5 can be adjusted according to the inner diameter of the weft cylinder 3. The O-ring 5 can also be replaced if it is damaged later. A step 15 is provided on the tube seat 2 to play a role in limiting. Similarly, the principle of inserting the weft cylinder 3 into the tube seat 2 is the same as the principle of sleeved on the tube seat 2, and can be reversed. If the inner diameter of the weft tube 3 is deformed to be smaller than the standard size, it can be inserted into the tube seat 2 by squeezing. Due to the action of the elastic member 4, the gap compensation is achieved, which will not affect the use and normal operation. On the contrary, when the inner diameter of the weft tube 3 is too large, it is only necessary to replace the appropriate elastic member 4. The elastic member 4 can be made of materials such as rubber and silicone. Example

[0036] like Figure 6-8 As shown, the elastic member 4 includes at least one elastic block 7 fixed to the outer wall of the weft cylinder 3 or the outer wall of the tube seat 2.

[0037] A groove 8 for the elastic block 7 to be embedded is provided on the outer periphery of the tube seat 2 or the weft tube 3 .

[0038] The outer peripheral wall of each elastic block 7 is set as an inclined arc surface 9. When either end of the weft tube 3 is matched with the corresponding tube seat 2, the inclined arc surface 9 can gradually clamp the two to achieve gap compensation.

[0039] Working principle: The end of the weft cylinder 3 can be sleeved outside the tube seat 2. The tube seat 2 is provided with an elastic block 7 in the circumferential direction. There is a height difference between the two ends of the inclined arc surface 9 of the elastic block 7. The end of the elastic block 7 close to the weft cylinder 3 is the lowest point. The preferred method in this embodiment is to evenly distribute multiple elastic blocks 7 along the circumference of the tube seat 2. During the assembly process of the two, they are gradually clamped to form a locking position for the weft cylinder 3, which plays a role in shock absorption and anti-slip. The size of the elastic block 7 can be adjusted according to the inner diameter of the weft cylinder 3. The elastic block 7 can also be replaced if it is damaged later. A step 15 is provided on the tube seat 2 to play a blocking and limiting role. Similarly, the principle of inserting the weft cylinder 3 into the tube seat 2 is the same as the principle of sleeved on the tube seat 2, and can be reversed. If the inner diameter of the weft tube 3 is deformed to be smaller than the standard size, it can be inserted into the tube seat 2 by squeezing. Due to the action of the elastic member 4, the gap compensation is achieved, which will not affect the use and normal operation. On the contrary, when the inner diameter of the weft tube 3 is too large, it is only necessary to replace the appropriate elastic member 4. The elastic member 4 can be made of materials such as rubber and silicone. Example

[0040] like Figure 9-11As shown, the elastic member 4 has a frustum portion 10 which is sleeved on the outside of the weft cylinder 3 or the tube seat 2, depending on the assembly method of the weft cylinder 3 and the tube seat 2, that is, the weft cylinder 3 is sleeved on the tube seat 2 or the weft cylinder 3 is inserted into the tube seat 2, and the outer wall of the tube seat 2 or the weft cylinder 3 is provided with an annular groove 6 for installing the frustum portion 10, and the outer peripheral wall of the frustum portion 10 is a frustum surface 11. When either end of the weft cylinder 3 is matched with the corresponding tube seat 2, the two can be gradually clamped based on the frustum surface 11 to achieve gap compensation.

[0041] An annular retaining ring 12 is provided at the outer end of the truncated cone portion 10 , and the annular retaining ring 12 blocks the outer end surface of the weft cylinder 3 or the outer end surface of the pipe seat 2 .

[0042] Working principle: The end of the weft cylinder 3 can be sleeved on the outside of the tube seat 2. The tube seat 2 is provided with a truncated cone 10 in the circumferential direction. The annular retaining ring 12 is provided at the end of the truncated cone 10 away from the weft cylinder 3. The truncated cone 11 is at the lowest point at the end close to the weft cylinder 3. During the assembly process of the weft cylinder 3 and the tube seat 2, the weft cylinder 3 is gradually clamped to form a locking position, which plays a role in shock absorption and anti-slip. The elastic member 4 can also be replaced if it is damaged later. The tube seat 2 is provided with a step 15 to play a blocking and limiting role. Similarly, the principle of inserting the weft cylinder 3 into the tube seat 2 is the same as the principle of sleeved on the tube seat 2, and the reverse can be performed. If the inner diameter of the weft cylinder 3 is deformed to be smaller than the standard ruler, it can be inserted into the tube seat 2 by squeezing. Due to the action of the elastic member 4, the gap compensation is achieved, which will not affect the use and normal operation. On the contrary, if the inner diameter of the weft cylinder 3 is too large, it is only necessary to replace the appropriate elastic member 4. The elastic member 4 can be made of rubber, silicone and other materials.

[0043] The present invention also provides a circular loom, including the above-mentioned embodiments 1, 2, and 3. No matter which one, it is necessary to ensure that one of the tube seats 2 can slide relative to the shuttle frame 1, or the two tube seats 2 can be brought together or away from each other at the same time, so as to adjust the distance between the two tube seats 2 to achieve the clamping of the weft tube 3. After clamping, the two tube seats 2 and the weft tube 3 rotate synchronously. A mounting portion 13 that slides with the tube seat 2 is fixed or integrally provided on the shuttle frame 1, and a lever 14 that drives it to slide along the length direction of the mounting portion 13 is provided on the tube seat 2; the tube seat 2 slides with the mounting portion through a pipe fitting or a shaft-like element, and the bearing 17 is fixed to the pipe fitting or a shaft-like element. The outer end of the shaft element, the tube seat 2 is sleeved on the outside of the bearing 17; a reset member 18 is provided in the mounting portion 13 for directly or indirectly driving the tube seat 2 to slide and reset, and a guide groove 16 is provided on the mounting portion 13. The guide groove 16 can be a long groove or a spiral shape. The shift rod 14 can be slidably set in the guide groove 16, and the reset member is a spring. In this embodiment, a preferred scheme is provided, in which a mounting portion 13 is provided at one end, and the other end of the shuttle frame 1 is fixed or integrally provided with a support, and a shaft element or pipe fitting and other connecting parts are also provided on the support. The bearing 17 is fixed to the outer end of the pipe fitting or shaft element (the end close to the weft tube 3), and the tube seat 2 is sleeved outside the bearing 17.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
