Description

Technical Field

[0001] This utility model belongs to the technical field of ring spinning machines, and specifically relates to an air frame for ring spinning machines. Background Technology

[0002] The air frame is applied to the collection system of the ring spinning machine to follow the up-and-down movement and inward and outward swinging movement of the herringbone arm, thereby driving the tube gripper on the air frame to move up-and-down and inward and outward swinging movements. Finally, based on the air supply of the air frame, the tube gripper of the collection system can grasp the tube during the collection process.

[0003] The air frame used in the traditional ring spinning frame's collection system has two T-slots on the mounting wall for installing the tube gripper. When installing the tube gripper, a limiting plate needs to be pre-installed in the two T-slots. Then, the mounting plate for the pre-installed tube gripper is connected to the limiting plates in the two T-slots using bolts. This connection process requires fixing the mounting plate to both limiting plates, which is labor-intensive and affects the overall assembly time. Furthermore, when the limiting plates in the T-slots are connected to the bolts, the bolts, after passing through the mounting plate and limiting plate, abut against the side wall of the T-slot. At this point, to avoid damaging the air frame, it is impossible to continue tightening the mounting plate by turning the bolts. If the mounting plate is not properly tightened at this point, it will affect the normal operation of the tube gripper during collection, thus affecting the overall output of the ring spinning frame. Utility Model Content

[0004] In view of this, the present invention provides an air frame for a ring spinning machine. The structure of the air frame is redesigned, and the cooperation between the snap-fit ​​groove and the mounting plate is used to reduce the process of connecting the mounting plate and the air frame by tightening bolts. The aim is to simplify the assembly process between the mounting plate and the air frame, save assembly time, and at the same time take into account the degree of tightness between the mounting plate and the air frame, ensuring that the mounting plate and the air frame are completely secure and there is no looseness.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An air frame for a ring spinning frame is applied to the ring spinning frame's loading system. The air frame, in cooperation with a herringbone arm assembly and a tube gripper, connects the tube gripper to the loading system to achieve tube gripping. The air frame includes:

[0007] The air frame body is a rectangular hollow tubular structure. Several air frame bodies are provided and connected end to end to form an air frame. The air frame body is connected to the A-frame arm assembly in the collection system through several connecting holes. In addition, the air frame body has a compressed air channel inside. The compressed air channel is integrally connected to the side wall of the air frame body and the side wall is configured as a mounting wall. Several ventilation holes are opened on the mounting wall. Each ventilation hole is connected to the compressed air channel, and every two adjacent ventilation holes are configured as a group of air holes.

[0008] The snap-fit ​​groove is L-shaped in general. The snap-fit ​​groove is composed of an integrally connected horizontal part and a vertical part, and the vertical part is located below the horizontal part. Several positioning notches are opened on the vertical part, and a group of air holes is arranged below each positioning notch. The snap-fit ​​groove is located on the mounting wall. The horizontal part of the snap-fit ​​groove is flush with the top of the air frame body and is integrally set.

[0009] A cross-shaped groove is formed on the mounting wall and located below the compressed air channel. The cross-shaped groove is composed of a vertical limiting cavity and a horizontal receiving cavity. A limiting plate is also provided in the limiting cavity.

[0010] Preferably, the interior of the air frame body is further provided with a first reinforcing plate, a second reinforcing plate and a third reinforcing plate, wherein the first reinforcing plate is located above the compressed air channel, the second reinforcing plate is integrally formed with the compressed air channel, and the third reinforcing plate is integrally formed with the cross-shaped groove. In addition, the first reinforcing plate, the second reinforcing plate and the third reinforcing plate are all parallel to each other.

[0011] Furthermore, the air frame also includes a connecting plate on one side of the air frame body. On the air frame body, the connecting hole is provided on the side wall opposite to the mounting wall. The air frame body is connected to the A-frame assembly through the cooperation of the connecting hole, the connecting plate, and screws. In addition, several connecting holes are respectively provided near both ends of the air frame body, so that two adjacent air frame bodies are connected to each other through the connecting plate.

[0012] Furthermore, the air frame also includes a mounting plate on the mounting wall. The top of the mounting plate extends into the "L"-shaped snap-fit ​​groove and mates with it. In addition, the top of the mounting plate is provided with a positioning protrusion that mates with the positioning notch. On this basis, the middle of the mounting plate is provided with two mating holes. When the top of the mounting plate extends into the snap-fit ​​groove and the positioning notch and the positioning protrusion mate with each other for positioning, the two mating holes communicate with the two vent holes in the corresponding air hole group. On the mounting plate, two pipe grippers are provided at positions corresponding to the two mating holes.

[0013] In addition, the bottom of the mounting plate is provided with a first mounting hole, and the first mounting hole and the horizontally structured receiving cavity in the "+" shaped groove are on the same horizontal plane. When the positioning notch and the positioning protrusion cooperate to position each other, the mounting plate is fixed to the air frame body through the cooperation of the first mounting hole, the second mounting hole preset on the limiting plate, and the bolt, thereby fixing the pipe gripper to the air frame.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention redesigns the air frame for the existing ring spinning machine's collection system. A snap-fit ​​groove is provided on the mounting wall of the air frame body, and a positioning notch is provided on the snap-fit ​​groove. Based on the one-to-one correspondence between the positioning notch and the air hole group on the mounting wall, when the top of the mounting plate extends into the snap-fit ​​groove and the positioning notch engages with the positioning protrusion on the mounting plate, the mounting plate achieves the required positional relationship with the air frame. At this point, the mounting plate can be positioned and installed using bolts and the first mounting hole on the bottom of the mounting plate, as well as the second mounting hole on the limiting plate. This is simpler than the existing technology where both limiting plates need to be positioned and installed with the mounting plate, thus improving installation efficiency.

[0016] Furthermore, based on the connection between the mounting plate and the gas frame, this utility model redesigns the T-slot in the prior art into a "+" shaped groove. With the bolt engaging with the first mounting hole at the bottom of the mounting plate and the second mounting hole on the limiting plate, the connection between the mounting plate and the gas frame is reinforced by continuing to tighten the bolt. If the end of the bolt passes through the limiting plate, the end of the bolt will extend into the receiving cavity without damaging the gas frame, demonstrating the practicality of this utility model.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] The air frame provided in this technical solution is applied to the yarn collection system of a ring spinning machine. It should be noted that the yarn collection system described in this application is a commonly used yarn collection system in existing ring spinning machines. It generally includes a yarn tube conveying mechanism, an air frame lifting mechanism, an air frame inward and outward swing mechanism, a yarn tube gripping mechanism, and a guide plate flipping mechanism. The control system, in conjunction with various sensors, enables the collaborative production of each mechanism to finally obtain the finished yarn. The air frame, herringbone arm assembly, and yarn gripper involved in this application are closely related to the air frame lifting mechanism, the air frame inward and outward swing mechanism, and the yarn tube gripping mechanism. Those skilled in the art can learn about these by consulting published patent documents and other prior art. Therefore, this application only describes the connection relationship between the air frame and the herringbone arm assembly and the yarn gripper, without elaborating on their working principles and other aspects.

[0025] In this technical solution, such as Figure 1 As shown, an air frame for a ring spinning machine includes: an air frame body 1, a snap-fit ​​groove 2, and a cross-shaped groove 3.

[0026] Among them, such as Figures 1-2 As shown, the air frame body 1 is a hollow tubular structure in the shape of a cuboid. There are several air frame bodies 1, and the air frame bodies 1 are connected end to end to form an air frame. The air frame body 1 is connected to the A-frame arm assembly in the collection system through several connecting holes 101. In addition, the air frame body 1 has a compressed air channel 102 inside. The compressed air channel 102 is integrally connected to the side wall of the air frame body 1, and the side wall is configured as a mounting wall 103. Several ventilation holes 104 are opened on the mounting wall 103. Each ventilation hole 104 is connected to the compressed air channel 102, and every two adjacent ventilation holes 104 are configured as a group of air holes.

[0027] Based on the above embodiments, the compressed air channel 102 in the air frame body 1 is used to provide air passage for the air frame body 1. The connection between the compressed air channels 102 caused by the connection of the two ends of the air frame body 1 adopts the sealed connection method of the compressed air channel 102 in the existing ring spinning machine collection system. This feature is not an improvement point of this application, and the specific structure can be obtained by consulting the prior art.

[0028] Regarding the connection method of the air frame body 1, where the ends are connected to form the air frame, such as... Figure 3 As shown, the air frame also includes a connecting plate 6 on one side of the air frame body 1. In addition, the present application also provides connecting holes 101 on the side wall opposite to the mounting wall 103. The air frame body 1 is connected to the A-frame assembly through the cooperation of connecting holes 101, connecting plate 6 and screws. On this basis, several connecting holes 101 are respectively provided near both ends of the air frame body 1, so that two adjacent air frame bodies 1 are connected to each other through connecting plates 6.

[0029] like Figures 1-2 As shown, the snap-fit ​​groove 2 is generally L-shaped. The snap-fit ​​groove 2 is composed of a horizontal part 201 and a vertical part 202 that are integrally connected. The vertical part 202 is located below the horizontal part 201. Several positioning notches 203 are provided on the vertical part 202, and a group of air holes is correspondingly arranged below each positioning notch 203. The snap-fit ​​groove 2 is located on the mounting wall 103. The horizontal part 201 of the snap-fit ​​groove 2 is flush with the top of the air frame body 1 and is integrally set.

[0030] Correspondingly, such as Figures 1-2 As shown, the "+" shaped groove 3 is also opened on the mounting wall 103 and is located below the compressed air channel 102. The "+" shaped groove 3 is composed of a vertical limiting cavity 301 and a horizontal receiving cavity 302. A limiting plate 4 is also provided in the limiting cavity 301.

[0031] Based on this, such as Figure 4As shown, the air rack provided in this application also includes a mounting plate 5 on the mounting wall 103. The top of the mounting plate 5 extends into the "L"-shaped snap-fit ​​groove 2 and engages with the snap-fit ​​groove 2. In addition, the top of the mounting plate 5 is provided with a positioning protrusion 501 that engages with the positioning notch 203. Based on this, the middle part of the mounting plate 5 is provided with two mating holes.

[0032] Based on the above embodiments, when the top of the mounting plate 5 extends into the snap-fit ​​groove 2 and the positioning notch 203 and the positioning protrusion 501 cooperate to position each other, the two mating holes are connected to the two ventilation holes 104 in the corresponding air hole group. On the mounting plate 5, two tube grippers are provided at the positions corresponding to the two mating holes. Thus, the tube grippers can realize their corresponding lifting and swinging movements in the collection system through the connection between the air frame body 1 and the herringbone arm assembly. At the same time, the compressed air channel 102 supplies air to the tube grippers through the cooperation of the mating holes and the ventilation holes 104, realizing their corresponding tube gripping action in the collection system. The specific cooperation method between the tube grippers and the ventilation holes 104 also adopts the sealing connection method at the corresponding position in the existing ring spinning machine collection system.

[0033] Based on the above structure, although the positional structure of the mounting plate 5 provides a precise positional basis for the installation of the pipe gripper, in actual operation, the stability of the installation between the mounting plate 5 and the air frame body 1 must also be considered. Specifically, for example... Figure 2 , Figure 4 As shown, the bottom of the mounting plate 5 is provided with a first mounting hole 502, and the first mounting hole 502 and the horizontally structured receiving cavity 302 in the cross-shaped groove 3 are on the same horizontal plane.

[0034] Based on the above embodiments, when the positioning notch 203 and the positioning protrusion 501 cooperate to position each other, the mounting plate 5 is fixed to the air frame body 1 through the cooperation of the first mounting hole 502 and the second mounting hole 401 preset on the limiting plate 4 and the bolt 7, and then the pipe gripper is fixed to the air frame. The structure is designed so that, under the premise that the bolt 7 cooperates with the first mounting hole 502 at the bottom of the mounting plate 5 and the second mounting hole 401 on the limiting plate 4, the connection between the mounting plate 5 and the air frame body 1 can be consolidated by continuing to tighten the bolt 7. If the end of the bolt 7 passes through the limiting plate 5, the end of the bolt 7 will extend into the receiving cavity 302 and will not cause damage to the air frame body 1, which reflects the practicality of this utility model.

[0035] In addition, this application also takes into account the structural strength of the air frame body 1, such as Figure 4As shown, the air frame body 1 is also provided with a first reinforcing plate 105, a second reinforcing plate 106 and a third reinforcing plate 107. The first reinforcing plate 105 is located above the compressed air channel 102, the second reinforcing plate 106 is integrally formed with the compressed air channel 102, and the third reinforcing plate 107 is integrally formed with the cross-shaped groove 3. Based on this, the first reinforcing plate 105, the second reinforcing plate 106 and the third reinforcing plate 107 are all parallel to each other. This arrangement enhances the structural strength of the air frame body 1.

[0036] Specifically, this utility model redesigns the air frame for the existing ring spinning machine's collection system. A snap-fit ​​groove 2 is provided on the mounting wall 103 of the air frame body 1, and a positioning notch 203 is provided on the snap-fit ​​groove 2. Furthermore, a cross-shaped groove 3 is provided on the mounting wall 103. Based on the above structure, during installation, the mounting plate 5 and the tube gripper are first connected according to the common connection method of the existing ring spinning machine collection system. Then, the top of the mounting plate 5 is inserted into the snap-fit ​​groove 2, and the positioning notch 203 and the positioning protrusion 501 are positioned in cooperation. At this time, the two mating holes on the mounting plate 5 are connected to the two ventilation holes 104 in the corresponding air hole group. The first mounting hole 502 at the bottom of the mounting plate 5 corresponds to the second mounting hole 401 pre-set on the limiting plate 4. Then, bolts 7 are used to engage with the first mounting hole 502 and the second mounting hole 401 to fix the mounting plate 5 to the air frame body 1, greatly saving assembly time.

[0037] In addition, the "+" shaped groove 3 allows the connection between the mounting plate 5 and the air frame body 1 to be reinforced by continuing to tighten the bolt 7, provided that the bolt 7 is engaged with the first mounting hole 502 and the second mounting hole 401. If the end of the bolt 7 passes through the limiting plate 5, the end of the bolt 7 will extend into the receiving cavity 302, which will not damage the air frame body 1, thus demonstrating the practicality of this utility model.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
