Description

Technical Field

[0001] This utility model relates to the field of DTY roll transportation, specifically DTY pallets. Background Technology

[0002] False twist textured yarn, also known as DTY or elastic yarn, is a type of textured yarn where the individual filaments intertwine and form a periodic network of dots in a network nozzle under the action of jetting air.

[0003] In the prior art, when DTY rolls are stored on pallets, foam boards are usually laid on the top and bottom sides of the pallet to prevent the DTY rolls from being damaged by friction due to relative displacement on the pallet during transportation.

[0004] However, because foam boards are easily damaged, the interaction force between the DTY roll and the foam board during pallet transportation can cause the foam board to break, thus preventing the foam board from effectively protecting and limiting the DTY roll. Utility Model Content

[0005] The purpose of this invention is to provide a DTY tray to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A DTY tray, wherein at least one of the extended trays is provided between the lower tray and the tray cover, the lower tray, multiple extended trays and the tray cover are stacked in sequence, and the upper surface of the lower tray, the upper surface of the extended tray, the lower surface of the extended tray and the lower surface of the tray cover are all provided with a number of limiting components for limiting and fixing the DTY rolls. The limiting component includes a cylindrical limiting groove and an annular guide groove surrounding the limiting groove. The annular guide groove is frustum-shaped. The limiting groove limits and fixes the winding shaft portion of the DTY roll, and the annular guide groove supports the yarn cake portion of the DTY roll. The DTY roll is positioned in the vertical direction by the limiting component.

[0007] Furthermore, the interior of the limiting groove is provided with a sealing plate to prevent the winding shaft of the DTY roll from falling off. The sealing plate is provided with a through hole, the diameter of which is smaller than the diameter of the limiting groove.

[0008] Furthermore, the annular guide groove includes an outer edge and an inner edge, and the wall formed between the outer edge and the inner edge is an annular inclined surface or an annular arc surface. The inclination angle of the connecting line between the outer edge and the inner edge of the annular guide groove is A, where 20°≤A≤40°.

[0009] Furthermore, the outer radius of the annular guide groove is set to L1, where 6cm≤L1≤12cm.

[0010] Furthermore, the radius of the limiting groove is set to L2, where 3cm≤L2≤6cm, and the inner radius of the annular guide groove is the same as the inner radius of the limiting groove.

[0011] Furthermore, when the wall of the annular guide groove is an annular arc surface, the curvature of the arc surface matches the curvature of the upper and lower edges of the DTY roll's yarn cake portion, and the outer radius of the annular guide groove is greater than the upper and lower edges of the DTY roll's yarn cake.

[0012] Furthermore, several connecting seats are fixedly connected to the lower tray, and the connecting seats have two through holes reserved on the lower tray so that the steel fork can lift the lower tray through the through holes.

[0013] Furthermore, a tray base is provided below the connecting seat, and several connecting blocks are fixedly connected above the tray base. The connecting blocks are inserted into the connecting seat, and the connecting blocks are fixed to the connecting seat by bolts.

[0014] Furthermore, a reinforcing rib is provided between the limiting component and the lower tray, and a reinforcing groove is provided around the limiting component, the extended tray, and the tray cover. Both the reinforcing groove and the reinforcing rib enhance the load-bearing capacity of the DTY tray.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model uses a limiting groove and an annular guide groove to limit and fix the upper and lower sides of the DTY roll. The limiting groove limits and fixes the part of the DTY roll that is wound around the shaft, and the inclined side of the annular guide groove can abut against the outer edge of the DTY roll cake part. When the limiting component limits the DTY roll, it is less likely to be damaged than the traditional foam board limiting structure and has a longer service life. Meanwhile, the frustum-shaped structure of the annular guide groove ensures that after the DTY roll is laid on the lower tray and the extension tray, as long as the part of the roll enters the inclined side of the frustum-shaped structure, it will slide along the inclined plate to the limiting groove in the center, saving the insertion step in the DTY roll placement process and greatly speeding up the placement efficiency of the DTY roll. By setting the radius and angle of the limiting groove and the annular guide groove, it is possible to facilitate the installation of DTY rolls into the limiting component, while also allowing the annular guide groove to better fit the surface of the DTY roll, increasing the contact area between the limiting component and the DTY roll, and avoiding localized contact between the pallet and the DTY roll, which could lead to localized compression damage to the DTY roll during transportation.

[0018] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0019] Please see Figures 1 to 5 The present invention provides a technical solution: a DTY tray, comprising a lower tray 1, an extension tray 3, and a tray cover 4, characterized in that at least one extension tray 3 is disposed between the lower tray 1 and the tray cover 4, the lower tray 1, multiple extension trays 3, and the tray cover 4 are stacked sequentially, and the upper surface of the lower tray 1, the upper surface of the extension tray 3, the lower surface of the extension tray 3, and the lower surface of the tray cover 4 are all provided with a plurality of limiting components 5 for limiting and fixing DTY rolls; The structure consisting of a lower pallet 1, multiple extension pallets 3, and a pallet cover 4 allows for the stacking of multiple layers of DTY rolls on a DTY pallet. The limiting components 5 on the upper surfaces of the lower pallet 1, the upper and lower surfaces of the extension pallets 3, and the lower surface of the pallet cover 4 can limit the movement of each layer of DTY roll, preventing them from detaching during pallet transport. Meanwhile, the limiting components 5 above the lower pallet 1 and multiple extension pallets 3 are used to support the DTY roll, while the limiting components 5 below the multiple extension pallets 3 and below the pallet cover 4 are engaged with the DTY roll below, preventing the multiple extension pallets 3 and pallet cover 4 from shaking during transportation, which would prevent the DTY roll from being effectively protected.

[0020] The limiting component 5 includes a cylindrical limiting groove 51 and an annular guide groove 52 surrounding the limiting groove 51. The annular guide groove 52 is frustum-shaped. The limiting groove 51 limits and fixes the winding shaft portion of the DTY roll, and the annular guide groove 52 supports the yarn cake portion of the DTY roll. The DTY roll is positioned in the vertical direction by the limiting component 5.

[0021] The DTY roll is inserted into the limiting component 5, so that the winding portion of the DTY roll is inserted into the limiting groove 51, limiting the entire DTY roll. At the same time, the annular guide groove 52 can support the yarn cake portion of the DTY roll. While limiting the DTY roll, it also disperses the force borne by the winding portion of the DTY roll, enhancing the limiting and protection functions of the DTY roll.

[0022] The limiting groove 51 is provided with a sealing plate 53 to prevent the winding shaft of the DTY roll from falling off. The sealing plate 53 is provided with a through hole 54, the diameter of which is smaller than the diameter of the limiting groove 51.

[0023] The structure of the sealing plate 53 enables the sealing plate 53 located below the winding shaft to provide support for the DTY roll. Meanwhile, the structure of the through hole 54 enables drainage. When the DTY tray is placed outdoors, water will accumulate on the surface of the tray cover 4. This water will enter the winding shaft through the through hole 54 and drain downwards through the through holes 54 on several extension trays 3, the middle of the winding shaft of each layer of DTY roll, and the through holes 54 on the lower tray 1, thus avoiding any impact on the DTY roll.

[0024] The annular guide groove 52 includes an outer edge and an inner edge. The wall formed between the outer edge and the inner edge is an annular inclined surface or an annular arc surface. The inclination angle of the connecting line between the outer edge and the inner edge of the annular guide groove 52 is A, where 20°≤A≤40°.

[0025] When the wall of the annular guide groove 52 is an annular arc surface, the curvature of the arc surface matches the curvature of the upper and lower edges of the DTY roll's yarn cake portion, and the outer radius of the annular guide groove 52 is greater than the upper and lower edges of the DTY roll's yarn cake.

[0026] By setting a certain tilt angle in the annular guide groove 52, when the DTY roll is placed on the tray below, the bottom of the winding shaft only needs to be placed within the range of the annular guide groove 52, and the winding shaft will automatically slide into the limiting groove 51 along the tilt angle of the annular guide groove 52, which greatly improves the loading efficiency of the DTY roll on the DTY tray. Meanwhile, the inner wall of the annular guide groove 52 can be set to an arc shape, so that the annular guide groove 52 can guide the winding shaft to the limiting groove 51 while completely conforming to the upper and lower edges of the yarn cake of the DTY roll, applying support force to the yarn cake part of the DTY roll, assisting the sealing plate 53 to support the DTY roll, and also limiting and protecting the DTY roll to prevent the DTY roll from falling off or being worn during pallet transportation.

[0027] The outer radius of the annular guide groove 52 is set to L1, where 6cm≤L1≤12cm.

[0028] With an outer radius of 6cm≤L1≤12cm, the annular guide groove 52 can completely wrap around the upper and lower outer edges of the DTY coil when limiting the DTY coil portion, and fit completely with the upper and lower edges of the DTY coil portion. This achieves the limitation and fixation of the DTY coil, while the force generated by collision and vibration during the transportation of the DTY pallet is evenly distributed on the coil and winding shaft of the DTY coil, avoiding damage caused by localized stress on the DTY coil.

[0029] The radius of the limiting groove 51 is set to L2, where 3cm≤L2≤6cm, and the inner radius of the annular guide groove 52 is the same as the inner radius of the limiting groove 51.

[0030] The radius of the limiting groove 51 is set within the range of 3cm≤L2≤6cm, and the inner radius of the annular guide groove 52 corresponds to the radius of the limiting groove 51. Even if the radius of the limiting groove 51 is smaller than the outer radius of the annular guide groove 52, the radius of the limiting groove 51 still needs to allow the conventional DTY winding reel to pass through.

[0031] Several connecting seats 12 are fixedly connected to the lower tray 1. The connecting seats 12 have two through holes reserved on the lower tray 1 so that the steel fork can lift the lower tray 1 through the through holes.

[0032] A tray base 2 is provided below the connecting seat 12, and a plurality of connecting blocks 21 are fixedly connected above the tray base 2. The connecting blocks 21 are inserted into the connecting seat 12, and the connecting blocks 21 and the connecting seat 12 are fixed together by bolts.

[0033] The pallet base 2 is fixed below the lower pallet 1 to prevent the connecting seat 12 from rubbing against the ground and causing damage to the one-piece molded lower pallet 1 during the dragging or sliding of the DTY roll. At the same time, the perforated structure between the connecting seat 12 and the pallet base 2 makes it easy for the forklift forks to pass through and lift the DTY pallet as a whole for transportation.

[0034] A reinforcing rib 11 is provided between the limiting component 5 and the lower tray 1. A reinforcing groove 31 is provided around the limiting component 5, the extended tray 3, and the tray cover 4. Both the reinforcing groove 31 and the reinforcing rib 11 enhance the load-bearing capacity of the DTY tray.

[0035] By using the structure of the reinforcing rib 11, the connection strength between the limiting component 5 and the lower tray 1 is increased, so that the part of the limiting component 5 on the lower tray 1 has a better load-bearing capacity, so that the lower tray 1 can also be effectively supported after the extension tray 3 is laid in multiple layers. The structure of the reinforced groove 31 is increased to increase the load-bearing area of ​​the extended tray 3 when bearing weight, thereby reducing the force on the limiting component 5 when bearing weight and preventing the overall weight of the multiple layers of the extended tray 3 from directly acting on the limiting component 5 on the extended tray 3, which would cause deformation.

[0036] The specific details of this plan are as follows: After the tray base 2 is installed, the lower tray 1 is placed horizontally on the ground. Since the length of both the upper and lower ends of the DTY roll is longer than the yarn portion of the DTY roll, the portion of the DTY roll below the winding shaft that extends beyond the yarn portion is moved into the limiting groove 51, and the yarn portion of the DTY roll is placed in the annular guide groove 52 of the lower tray 1. After the DTY roll is installed on the lower tray 1, move the extension tray 3 above the DTY roll and make the limiting component 5 below the extension tray 3 snap into the top of the DTY roll, and install the DTY roll on the top of the extension tray 3 according to the above steps. The structure of multiple sets of expansion trays 3 is used to stack the expansion trays 3 to fix multiple layers of DTY rolls. The tray cover 4 is installed on the top layer of DTY roll in the same way as the expansion tray 3. The entire tray is wrapped with a protective film after the DTY roll is installed. The tray cover 4, the lower tray 1 and the multiple expansion trays 3 are fixed together to complete the overall installation of the DTY tray.

[0037] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, 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.
