Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, and more specifically, to a wall panel in a spinning machine for collective doffing modification. Background Technology

[0002] Ring spinning machines are crucial pieces of equipment in the textile industry, affecting a large scale and wide volume of production. Their performance directly impacts yarn quality, economic benefits, and other aspects. The doffing process in ring spinning is the most labor-intensive; therefore, ring spinning machines equipped with highly automated collective doffing devices have become the mainstream in the market. The existing collective doffing device in ring spinning machines operates as follows: a doffing air frame with a doffing gripper moves up and down under the action of a herringbone linkage mechanism. Under the action of a laterally moving inlet / outlet cylinder, it swings along the inlet / outlet direction with the herringbone linkage mechanism. The doffing gripper approaches or leaves the bobbin through the rising, falling, and swinging motion of the doffing air frame, thus achieving the gripping and lowering of the bobbin. The bobbin holder, which fixes the bobbin in a cyclical motion by the bobbin seat below the collective doffing device, enables the bobbin gripper to store and grab empty bobbins and doffing bobbins. Other mechanisms then transport and load / unload the bobbins at the head and tail of the machine. This herringbone linkage mechanism is simple and reliable, but its motion requires that the spinning position of the bobbin and the bobbin storage / retrieval position on the lower bobbin seat be on a vertical straight line.

[0003] The existing patent CN115198407B modifies the middle wall plate of a spinning frame by cutting the outer portion of the wall plate support legs. This allows the bobbin conveying track to be installed on the outer side of the support legs, ensuring that the bobbin grabber can vertically grab and insert bobbins at the spindle and bobbin seat. However, the cut wall plate support legs have reduced width, and the ribs are removed, leading to decreased stability of the middle wall plate, reduced maintenance cycles, and decreased connection stability. Therefore, it is necessary to provide a solution for reinforcing the middle wall plate of a spinning frame for collective doffing modification to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a solution for reinforcing the wall panels in a spinning machine used for collective doffing modification, thereby overcoming the aforementioned defects in the prior art.

[0005] The technical solution to achieve the purpose of this utility model is: a wall panel for a spinning machine used in the collective doffing modification, comprising a wall panel, wherein wall panel support legs are symmetrically provided on the left and right sides of the bottom of the wall panel; a cutting notch is provided on the outer side of the wall panel support leg, and a boss is formed below the cutting notch of the wall panel support leg; the front of the wall panel support leg is L-shaped; the width of the boss is equal to the width of the cutting notch; and a reinforcing plate to enhance the load-bearing capacity and stability is fixedly connected to the wall panel support leg.

[0006] Furthermore, the reinforcing plate includes a reinforcing main plate, the front of which is L-shaped like the front of the wall panel support leg; the wall panel support leg is integrally connected to the wall panel through an inclined first connecting plate, the reinforcing main plate is connected through an inclined second connecting plate and a third connecting plate parallel to the reinforcing main plate, and the third connecting plate (205) is fixedly connected to the wall panel; the reinforcing main plate and the wall panel support leg are symmetrically arranged along the front of the wall panel.

[0007] Furthermore, the outer side of the wall panel support leg is connected to an outer side plate, the inner side is connected to an inner side plate, and the bottom side is connected to a bottom plate. The outer side plate, the inner side plate, and the bottom plate are respectively arranged perpendicular to the wall panel support leg.

[0008] Furthermore, the reinforced motherboard is also provided with reinforced outer side plates and reinforced inner side plates on both sides, corresponding to the outer side plate and the inner side plate.

[0009] Furthermore, the reinforced outer side plate is fixedly connected to the outer side plate by fasteners, the base plate is fixedly connected to the reinforced main plate by fasteners, and the third connecting plate is fixedly connected to the wall panel by fasteners.

[0010] Furthermore, an adjustable pad is connected below the base plate.

[0011] Furthermore, the wall panel support leg is provided with a first strip hole and a second strip hole respectively arranged parallel to the outer side of the wall panel support leg; the first strip hole is located outside the second strip hole.

[0012] Further, the width of the first strip hole is *a*, the width from the outer edge of the wall panel support leg to the edge of the first strip hole near its outer edge is *b*, and the width of the cutting notch is *X*; Option 1: *X* satisfies: *b* ≤ *X* < *a* + *b*. Option 2: *X* < *b*.

[0013] Further, the distance from the bottom edge of the second strip-shaped hole to the bottom edge of the wall panel support leg is c, and the height of the boss is Y; Scheme 1: Y satisfies: 0 < Y ≤ c. Scheme 2: Y ≥ c

[0014] By adopting the above technical solution, this utility model has the following beneficial effects:

[0015] (1) By cutting the wall panel support leg, the pipe grabber can grab and put the pipe vertically at the spindle and pipe seat. This eliminates the need for new mechanisms, ensures high stability, shortens the construction period, and significantly reduces costs. The cutting makes the front of the support leg L-shaped and the other support leg in reverse L-shape. The protrusion formed at the bottom maintains the original width of the support leg, which helps to increase the contact area and load-bearing capacity of the support surface and avoids the strength reduction caused by the cutting of the protruding ribs of the wall panel support leg. By adding a reinforcing plate, the load-bearing capacity and overall rigidity of the support leg are significantly improved, preventing deformation or breakage and extending the service life.

[0016] (2) After cutting the wall panel, this utility model retains at least one strip hole for the installation and adjustment of bolts or other fasteners, which facilitates on-site adjustment of the assembly position.

[0017] (3) The cutting width design of this utility model ensures that the cutting notch is neither too wide to affect the structural strength, nor too narrow to affect the functionality of the strip hole.

[0018] (4) The design of the boss height Y of this utility model ensures that the boss will not be too high and affect the space utilization below the strip hole.

[0019] (5) The outer side plate, inner side plate, bottom plate and support leg of this utility model are vertically connected to form a stable frame structure, which improves the overall bending and torsion resistance; the additional plate provides more connection points, which facilitates subsequent connection with guide rail and transmission mechanism.

[0020] (6) The present invention provides a reinforced main board along the symmetrical axis of the wall panel, which makes the force more uniform and avoids structural instability caused by eccentric loading; the double fixing method can strengthen the main board to connect the wall panel and the support leg at the same time, play a bridging role, and further enhance the rigidity and stability of the overall structure; it can improve the earthquake resistance and fatigue resistance. In the long-term operation, this reinforcement method can effectively resist fatigue damage caused by vibration.

[0021] (7) The present invention strengthens the main board and the inner and outer side plates to form a three-dimensional strengthening system, which significantly improves the overall load-bearing capacity and deformation resistance; the internal and external synergistic strengthening not only strengthens the external stress area, but also reinforces the internal structure to prevent overall failure caused by local weakness.

[0039] (Example 1)

[0040] In the existing patent with publication number CN115198407B, the middle wall plate of a spinning frame is modified by partially cutting the outer part of the wall plate support legs. This allows the full and empty bobbin conveying tracks, installed on the outside of the wall plate support legs, to pass smoothly through the middle wall plate, ensuring that the bobbin grabber can vertically grab and insert bobbins at the spindle and bobbin seat. However, the width of the wall plate support legs is reduced after cutting, and some of the protruding ribs are cut off, resulting in decreased stability of the middle wall plate, reduced maintenance cycle, and decreased connection stability.

[0041] This embodiment is a further modification based on the existing one, see... Figure 1 , Figure 2 and Figure 3A wall panel for a spinning machine used in a collective doffing modification includes a wall panel 100, with symmetrical wall panel support legs 110 on the left and right sides of the bottom of the wall panel 100; the outer side of the wall panel support leg 110 has a cutting notch 111, and a boss 112 is formed below the cutting notch 111 of the wall panel support leg 110; the front of the wall panel support leg 110 is L-shaped, and the front of the other wall panel support leg is reverse L-shaped; the width of the boss 112 is equal to the width of the cutting notch 111; the wall panel support leg 110 is also fixedly connected to a reinforcing plate 200 to enhance load-bearing capacity and stability.

[0042] By cutting the wall panel support legs, the pipe grabber can grab and insert the pipe at the spindle and pipe seat in the same vertical direction. This eliminates the need for new mechanisms, ensuring high stability, shortening the construction period, and significantly reducing costs. The cutting process creates an L-shaped front for the support legs, and the resulting boss at the bottom maintains the original width of the support legs, which helps to increase the contact area and load-bearing capacity of the support surface and avoids a decrease in strength due to cutting. By adding reinforcing plates, the load-bearing capacity and overall rigidity of the support legs are significantly improved, preventing deformation or breakage and extending service life.

[0043] Further details can be found here. Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9 The reinforcing plate 200 includes a reinforcing main plate 201, the front of which is L-shaped, the same as the front of the wall panel support leg 110. The wall panel support leg 110 is integrally connected to the wall panel 100 through an inclined first connecting plate 118. The reinforcing main plate 201 is connected to a third connecting plate 205 parallel to the reinforcing main plate through an inclined second connecting plate 204. The third connecting plate 205 is fixedly connected to the wall panel 100. The bending design between the reinforcing main plate 201, the second connecting plate 204, and the third connecting plate 205 enhances the strength of the reinforcing plate 200. The reinforcing main plate 201 and the wall panel support leg 110 are symmetrically arranged on the left and right sides of the wall panel 100.

[0044] The wall panel support leg 110 has an outer side plate 115 connected to its outer side, an inner side plate 116 connected to its inner side, and a bottom plate 117 connected to its bottom edge. The outer side plate 115, inner side plate 116, and bottom plate 117 are respectively perpendicular to the wall panel support leg 110. The reinforcing main plate 201 also has reinforcing outer side plates 202 and reinforcing inner side plates 203 on both sides, corresponding to the outer side plates 115 and inner side plates 116, further strengthening the reinforcing plate 200. The reinforcing outer side plate 202 is fixedly connected to the outer side plate 115 by fasteners, and the bottom plate 117 is also fixedly connected to the reinforcing main plate 201 by fasteners. The connecting plate 205 connected to the upper part of the second connecting plate 204 is parallel to the reinforcing main plate 201, and 205 is also fixedly connected to the wall panel 100 by fasteners.

[0045] The outer, inner, and bottom plates of the central wall panel are vertically connected to the supporting legs, forming a stable frame structure. The cut central wall panel retains part of this frame structure, improving overall bending and torsional resistance. Additional reinforcing plates not only provide more connection points for subsequent connection with guide rails and transmission mechanisms, but also restore and strengthen the strength of the central wall panel. Reinforcing main plates are installed along the wall panel's axis of symmetry, ensuring more even stress distribution and preventing structural instability caused by eccentric loading. The dual-fixing method allows the reinforcing main plate to connect both the wall panel and the supporting legs, acting as a bridge and further enhancing the overall structural rigidity and stability. This improves seismic and fatigue resistance; during long-term operation, this reinforcement method effectively resists fatigue damage caused by vibration. The reinforcing main plate and the inner and outer plates form a three-dimensional reinforcement system, significantly improving overall load-bearing capacity and deformation resistance. This synergistic reinforcement not only strengthens external stress areas but also reinforces the internal structure, preventing overall failure due to localized weaknesses.

[0046] Furthermore, a pad 120 with adjusting bolts is connected below the base plate 117. The adjusting bolts can adjust the height of the wall panel to adapt to the modification of the spinning machine.

[0047] Further details can be found here. Figure 1 and Figure 2 The wall panel support leg 110 has a first strip hole 113 and a second strip hole 114, which are respectively arranged parallel to the outer side of the wall panel support leg 110. The first strip hole 113 and the second strip hole 114 are symmetrically arranged and have the same height. The first strip hole 113 is located outside the second strip hole 114. The width of the first strip hole 113 is 'a', the width from the outer side of the wall panel support leg 110 to the edge of the first strip hole 113 near the outer side is 'b', and the width of the cutting notch 111 is 'X'; X satisfies: b ≤ X < a + b. The distance from the bottom edge of the second strip hole 114 to the bottom edge of the wall panel support leg 110 is 'c', and the height of the boss 112 is 'Y'; Y satisfies: 0 < Y ≤ c. The strip holes are designed for the installation and adjustment of bolts or other fasteners, facilitating on-site adjustment of the assembly position. The cutting width design ensures that the cutting notch is neither too wide to affect the structural strength nor too narrow to affect the functionality of the strip hole. The boss height Y is designed to ensure that the boss is not too high to affect the utilization of the space below the strip hole.

[0048] Further details can be found here. Figure 7 Another cluster modification scheme involves moving the ribs 400 on both sides of the spinning machine a certain distance to the sides (generally 15-25mm, typically 20mm). This causes the spindles mounted on the ribs and the tracks 300 below to also move a corresponding distance to the sides. This, in turn, allows for the creation of the cutting notch 111 (such as...) for the required wall panel cutting. Figure 2The size of the wall panel is also reduced to enhance its strength, and the two original slots 113 and 114 on the individual wall panel support leg 110 are fully retained. At this time, X < b; Y ≤ c or Y ≥ c are satisfied. This scheme is used less often because the quality of the yarn spun by the spinning machine tends to be poor; however, it is frequently used when the spinning machine is equipped with a compact spinning device.

[0049] See Figure 6 The image shows a three-dimensional view of the modified middle wall panel of a spinning frame. To achieve a high degree of automation in the spinning frame, the doffing process is automated. By cutting the middle wall panel, the spinning position of the yarn bobbin and the bobbin storage and retrieval position on the lower bobbin seat are aligned on a vertical straight line. This enables the automatic lifting and lowering movement of the air collection frame under the action of the herringbone linkage mechanism, improving the level of automation and reducing the company's modification costs.

[0050] See Figure 7 The diagram shows the installation of the central wall panel. The modified platform is equipped with a track and a reinforcing plate to further strengthen the support legs of the wall panel, making the modified central wall panel more stable and with better load-bearing capacity.

[0051] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
