[0038] In the description of the present application, it should be understood that when one component is considered to be "connected" to another component, it can be directly connected to the other component or there can be a component arranged in the middle. When one component is considered to be "arranged on" another component, it can be directly arranged on the other component or there can be a component arranged in the middle.

It cannot be understood as a limitation of the present application.
[0040] The technical solutions of the present application will be further described below in combination with the specific embodiments. Figures 1-4 The technical solutions of the present application will be further described below in combination with the specific embodiments.
[0041] Please refer to Figure 1The utility model embodiment provides a kind of yarn parking device, including parking device body 1, stop lever 2 and first clamping component 3.Wherein, parking device body 1 mainly includes shell, control element, electrode element and bracing arm 11, bracing arm 11, control element and motor element are respectively installed with shell place;Specifically, bracing arm 11 is rotatably arranged in one side of parking device body 1, and bracing arm 11 is provided with elastic member between shell, when elastic member is in natural state, bracing arm 11 swings upward;At the same time, bracing arm 11 is used for yarn guiding, and yarn exists tension in the process of feeding, so bracing arm 11 will be pressed down, when bracing arm 11 is connected with control element, control element can identify whether yarn is in normal feeding state based on the state of bracing arm 11, and its specific identification control mode is not specifically described here.
[0042] On this basis, to improve the operation efficiency when debugging the equipment or replacing the yarn, the movement of the bracing arm 11 is limited by setting the stop lever 2 and the first clamping component 3.
[0043] Specifically, the stop lever 2 is located at one side of the parking device body 1 near the end of the bracing arm 11, and the length of the stop lever 2 is greater than the width of the side of the shell. The stop lever 2 in this embodiment is made of plastic material and has a long straight rod structure to have elastic deformation capability. At this time, one end of the stop lever 2 is rotatably arranged on the parking device body 1. When the stop lever 2 rotates, the other end can extend to the outside of the shell, thereby abutting and limiting the bracing arm 11.
[0044] Further, with reference to Figure 2 The first clamping component 3 is arranged on the parking device body 1 and movably connected with the stop lever 2 to avoid loosening of the stop lever 2 when limiting the bracing arm 11. Based on this, referring back to Figure 1 When the stop lever 2 is connected with the first clamping component 3, the other end of the stop lever 2 abuts and limits the bracing arm 11, so that the parking device body 1 remains in a non-working state when the yarn is separated from the bracing arm 11.
[0045] By adopting the above scheme, the yarn parking device provided by the embodiment can abut and limit the bracing arm 11 under the clamping action of the first clamping component 3 by turning the stop lever 2. Thus, the bracing arm 11 will not be triggered to stop in the case of loosening the yarn, thereby keeping a non-working state. This is equivalent to keeping the bracing arm 11 in a state where the yarn has not been broken. Therefore, when stopping and debugging or replacing the yarn type, it is not necessary to disassemble the entire yarn feeder or parking device. It needs to be explained that the yarn feeder is usually arranged at a height of more than one meter and eight, so as to effectively reduce the workload of the operator and improve the overall operation efficiency.
[0046] Continuing to refer to Figure 2To realize the clamping of the stop lever 2, the first clamping assembly 3 in the embodiment includes a first wave point 31. The first wave point 31 is arranged on the parking device body 1. Specifically, the first wave point 31 can be fixedly arranged on one side of the housing or integrally formed on one side of the housing. The first wave point 31 protrudes from the side of the housing.
[0047] At the same time, in combination with Figure 3 The stop lever 2 is provided with a first clamping groove 21 on the side close to the parking device body 1. The first clamping groove 21 is recessed on the surface of the stop lever 2. When the stop lever 2 rotates, the first wave point 31 is on the displacement path of the first clamping groove 21. At this time, in the process of moving the stop lever 2 to the first wave point 31, the stop lever 2 will be raised when it touches the first wave point 31, thereby achieving the effect of avoiding. With the continuous movement of the stop lever 2, the first wave point 31 will slide into the first clamping groove 21. At this time, the stop lever 2 returns to the state before deformation. When the stop lever 2 needs to be released, it can be reversed. The stop lever 2 is actuated. Details are omitted here. The operation is convenient and fast, and the quick switching of the limiting action can be realized.
[0048] Further, in the actual operation process, if the force when the stop lever 2 rotates is too large, it may cause the displacement of the stop lever 2 to be too large, thereby causing the clamping of the first wave point 31 and the first clamping groove 21 to be inaccurate.
[0049] Based on this, the first clamping assembly 3 further includes a first limiting block 32, and the first limiting block 32 is arranged on the parking device body 1. In the embodiment, the first limiting block 32 is integrally connected to the housing, and the first limiting block 32 is arranged adjacent to the first wave point 31. At this time, when the first wave point 31 is clamped with the first clamping groove 21, one side of the first limiting block 32 abuts and limits one side of the stop lever 2, thereby preventing the stop lever 2 from excessive displacement, and the stop lever 2 is actuated more accurately.
[0050] Further, the first wave point 31 has an arc-shaped guide surface 5. Specifically, the arc-shaped guide surface 5 is located on the side of the first wave point 31 away from the parking device body 1. In the embodiment, the arc-shaped guide surface 5 has a spherical profile. The first wave point 31 can slide and abut with the stop lever 2 through the arc-shaped guide surface 5, so that the first wave point 31 is smoothly clamped into the first clamping groove 21. The operation is more smooth, and the use experience is improved.
[0051] Referring to Figures 1 to 3When the stop lever 2 does not need to limit the support arm 11, the stop lever 2 can be pushed back to the position close to the parking device body 1, and at this time, in order to prevent the stop lever 2 from extending out of the parking device body 1 by itself, the yarn parking device disclosed in the embodiment further comprises a second clamping component 4 arranged on the parking device body 1, when the stop lever 2 is clamped on the second clamping component 4, the stop lever 2 and the support arm 11 are mutually released, and since the stop lever 2 is limited by the second clamping component 4, the parking device body 1 can be in a stable normal working state and is not easy to be disturbed.
[0052] In the embodiment, the structure of the second clamping component 4 is the same as that of the first clamping component 3, specifically, the second clamping component 4 comprises a second wave point 41 arranged on the parking device body 1.
[0053] Specifically, the second wave point 41 is fixedly arranged on the outside of the shell, and the second wave point 41 protrudes from the side surface of the shell, at the same time, the side of the stop lever 2 close to the parking device body 1 is provided with a second clamping groove 22, and the second clamping groove 22 is staggered with the first clamping groove 21 in the length direction of the stop lever 2, when the stop lever 2 rotates, the second wave point 41 is in the displacement path of the second clamping groove 22, at this time, in the process of moving the stop lever 2 to the second wave point 41, first, since the stop lever 2 has a certain deformation space, when the stop lever 2 touches the second wave point 41, the stop lever 2 will be raised, thereby achieving the effect of avoiding, with the continuous movement of the stop lever 2, the second wave point 41 will slide into the second clamping groove 22, at this time, the stop lever 2 returns to the state before deformation, when it is needed to release the stop lever 2, the stop lever 2 can be reversely moved, and the specific principle is not described herein, the second wave point 41 and the second clamping groove 22 are movably clamped through the above arrangement.
[0054] Further, the second clamping component 4 further comprises a second limiting block 42 arranged on the parking device body 1. In the embodiment, the second limiting block 42 is integrally connected to the shell, when the second wave point 41 is clamped with the second clamping groove 22, the second limiting block 42 abuts and limits one side of the stop lever 2, thereby preventing the stop lever 2 from excessive displacement.
[0055] Further, the second wave point 41 is also provided with an arc-shaped guide surface 5, the arc-shaped guide surface 5 is located on the side of the second wave point 41 away from the parking device body 1, and the second wave point 41 slides and abuts with the stop lever 2 through the arc-shaped guide surface 5, so as to smoothly clamp the second wave point 41 into the second clamping groove 22, and the use experience is improved.
[0056] Reference Figure 3In order to enable the stop lever 2 to stably provide the limiting support to the support arm 11, in the embodiment, the stop lever 2 comprises a rotating shaft part 24 and a body part 23, the first clamping groove 21 and the second clamping groove 22 are arranged on the body part 23, the body part 23 is connected with the rotating shaft part 24, specifically, one end of the rotating shaft part 24 is integrally connected with one end of the body part 23, and the two are perpendicular to each other, so that the stop lever 2 has good structural stability.
[0057] On this basis, combined with Figure 4 The parking device body 1 is provided with a mounting groove 6, the mounting groove 6 is recessed on the side of the shell close to the support arm 11, the rotating shaft part 24 is inserted into the mounting groove 6, and the rotating shaft part 24 is rotatably arranged on the parking device body 1 through the mounting groove 6, under the guidance of the rotating shaft part 24, the body part 23 can swing, at this time, the body part 23 can be clamped and matched with the first clamping assembly 3, clamped and matched with the second clamping assembly 4, and abutted and limited to the support arm 11.
[0058] Further, referring to Figure 3 and Figure 4 Further, the spring 25 is sleeved on the rotating shaft part 24, and the two ends are respectively connected with the rotating shaft part 24 and the parking device body 1. Specifically, the first step 7 is integrally arranged on the rotating shaft part 24, at the same time, the second step 8 is arranged in the shell; at this time, the two ends of the spring 25 are respectively abutted with the first step 7 and the second step 8, based on this arrangement, the spring 25 applies a spring force to the stop lever 2 through the first step 7, so that the stop lever 2 is pressed and combined on the parking device body 1, and because the first step 7 abuts with the inner wall of the shell at this time, the friction force acting on the stop lever 2 is increased, the stop lever 2 can stay at any angle, the stop lever does not swing at will at a certain fixed position, and it is more reliable to use.
[0059] The yarn parking device provided in the embodiment has the following beneficial effects:
[0060] 1. Through the stop lever structure, the parking device body 1 can be freely switched between the normal working state and the non-working state, without the need to climb high to disassemble the whole yarn feeder or the parking device, which provides optimization in reducing the workload of the operator and improving the work efficiency;
