Abstract
Description
Technical Field
[0001] The utility model relates to the field of spinning frames, in particular to an apron rack and a toothed drafting apron. Background Art
[0002] In the textile industry, as one of the key equipment in the spinning production line, the performance of the spinning frame directly affects the quality and production efficiency of the yarn. As an important component in the spinning frame, the apron rack undertakes the key tasks of yarn drafting and transmission.
[0003] During the spinning process, under the high-speed operation and complex tension changes of the spinning frame, the distance between the feed roller shaft and the drafting roller shaft is relatively large. It is difficult to effectively fix the yarn in this area, which causes the yarn to vibrate easily and affects the smooth transportation and final quality of the yarn.
[0004] The existing patent CN209210989U provides a three-roller drafting mechanism for ramie spinning frames. By introducing an intermediate support component between the feed roller shaft and the drafting roller shaft, the apron can hold the yarn and provide a transition for the yarn. However, the surface of its apron is mostly flat-designed and lacks an anti-slip structure, so it is prone to slipping under conditions such as yarn tension changes or humidity changes. This not only affects the quality stability of the yarn but also may cause production accidents such as yarn breakage. Summary of the Utility Model
[0005] The purpose of the utility model is to provide an apron rack and a toothed drafting apron, and solve the following technical problems: how to improve the force uniformity and linear diameter uniformity of the yarn, and how to improve the installation convenience and stability of the apron rack.
[0006] To solve the problems existing in the prior art, the technical scheme adopted by the utility model is as follows:
[0007] An apron rack includes a support plate, side plates, a runner and a main rotating rod. Both sides of the support plate are fixedly connected with side plates in an arc-shaped bending shape. The bottom ends of the side plates are bent in a hook shape. A runner is rotatably connected between the top ends of the side plates, and a main rotating rod is rotatably connected between the bottom ends of the side plates.
[0008] Preferably, auxiliary rotating rods are symmetrically and rotatably connected to the top of the side plates. The setting of the auxiliary rotating rods further optimizes the transmission efficiency of the apron.
[0009] Preferably, annular grooves are opened at both ends of the main rotating rod and the auxiliary rotating rods. Grooves are provided at the corresponding positions of the side plates and the two ends of the main rotating rod and the auxiliary rotating rods. The shape of the grooves matches that of the annular grooves. The annular grooves at both ends of the main rotating rod and the auxiliary rotating rods are respectively embedded in the corresponding grooves, so that the main rotating rod and the auxiliary rotating rods can be stably installed on the side plates. Through the embedded installation method, it is convenient for the disassembly and maintenance of the main rotating rod and the auxiliary rotating rods.
[0010] Preferably, the auxiliary rotating rod is symmetrically arranged at the bent part of the top of the side plate, providing additional support and guidance for the apron, ensuring that the apron maintains a stable shape and tension during rotation.
[0011] Preferably, hexagonal grooves are provided at both ends of the main rotating rod and the auxiliary rotating rod, which provides certain convenience for tool installation or disassembly.
[0012] Preferably, the top and bottom of the support piece are both curved downward in an arc shape, avoiding rubbing during the transmission of the apron.
[0013] A toothed drafting apron for the above-mentioned apron holder. An apron is provided between the side plates. The apron is sleeved outside the support piece, the rotating wheel, the main rotating rod and the optional auxiliary rotating rod in a surrounding manner. Tooth-shaped anti-slip lines are provided in the middle of the surface of the apron.
[0014] Preferably, the width of the anti-slip lines is greater than one-third of the total width of the apron.
[0015] Compared with the related art, the utility model has the following beneficial effects:
[0016] 1. By introducing a toothed drafting apron with tooth-shaped anti-slip lines, the utility model enhances the friction and holding force of the apron on the yarn, effectively preventing the yarn from shaking and sagging during transportation, ensuring uniform force on the yarn. At the same time, the design of the tooth-shaped anti-slip lines can also improve the wear resistance and adaptability of the apron, adapting to the requirements of different specifications and materials of the yarn, thereby further improving the uniformity and overall quality of the yarn diameter drawn out.
[0017] 2. By optimizing the structural design of the apron holder, adding easy-to-operate fasteners and stable hook-shaped bending of the side plates, the installation process of the apron holder is made more simple and rapid. At the same time, the adaptability and stability of the apron holder to the roller shaft of the spinning frame are enhanced, effectively reducing looseness and failures caused by improper installation or vibration, ensuring the stability and reliability of the apron holder during high-speed operation.

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0023] A leather apron holder includes a support plate 1, side plates 2, a runner 3 and a main rotating rod 4;
[0024] As Figures 1 to 3 shown, both sides of the support plate 1 are fixedly connected with side plates 2 bent in an arc shape. The bottom ends of the side plates 2 are bent in a hook shape. A runner 3 is rotatably connected between the top ends of the side plates 2, and a main rotating rod 4 is rotatably connected between the bottom ends of the side plates 2;
[0025] The design of the leather apron holder fully considers the compatibility with the spinning frame. The side plates 2 bent in an arc shape on both sides not only enhance the structural stability but also facilitate the stable installation of the leather apron holder on the roller shaft of the spinning frame. The hook-shaped bending design at the bottom ends of the side plates 2 can tightly hook the bracket below the roller shaft, ensuring that the leather apron holder will not loosen or fall off during high-speed operation;
[0026] As the core load-bearing component, the support plate 1 effectively supports the stability of the leather apron when carrying yarn. At the same time, the runner 3 and the main rotating rod 4 form an efficient transmission system through the surrounding of the leather apron. When the roller shaft rotates, the runner 3 and the main rotating rod 4 are driven to rotate synchronously through the friction of the leather apron, realizing the smooth conveying of the yarn.
[0027] As Figures 1 to 3 shown, auxiliary rotating rods 5 are symmetrically and rotatably connected to the top of the side plates 2. The setting of the auxiliary rotating rods 5 further optimizes the transmission efficiency of the leather apron. The auxiliary rotating rods 5 and the main rotating rod 4 act together to enhance the overall stability and durability of the leather apron holder.
[0028] As Figures 1 to 3 shown, annular grooves 6 are opened at both ends of the main rotating rod 4 and the auxiliary rotating rods 5. Grooves 7 are provided at the corresponding positions of the side plates 2 and the two ends of the main rotating rod 4 and the auxiliary rotating rods 5. The shape of the grooves 7 matches that of the annular grooves 6. The annular grooves 6 at both ends of the main rotating rod 4 and the auxiliary rotating rods 5 are respectively embedded in the corresponding grooves 7;
[0029] The precise cooperation between the annular grooves 6 opened at both ends of the main rotating rod 4 and the auxiliary rotating rods 5 and the grooves 7 on the side plates 2 realizes gapless rotation. At the same time, this embedded installation method also facilitates the installation and disassembly of the main rotating rod 4 and the auxiliary rotating rods 5.
[0030] As Figures 1 to 3 shown, the auxiliary rotating rods 5 are symmetrically arranged at the bent parts at the top of the side plates 2, providing additional support and guidance for the leather apron to ensure that the leather apron maintains a stable shape and tension during rotation.
[0031] As Figures 1 to 3As shown, hexagonal slots 8 are provided at both ends of the main rotating rod 4 and the auxiliary rotating rod 5. The provision of the hexagonal slots 8 facilitates the use of tools for fastening or disassembling the rotating rods.
[0032] As Figures 1 to 3 shown, the top and bottom of the side plate 2 are both curved downward in an arc shape.
[0033] As Figure 1 and Figure 2 shown, a toothed drafting apron is used for the above-mentioned apron frame. An apron is provided between the side plates 2. The apron is sleeved on the outside of the support piece 1, the rotating wheel 3, the main rotating rod 4 and the optional auxiliary rotating rod 5 in a surrounding manner. Tooth-shaped anti-slip lines 9 are provided in the middle of the surface of the apron. These anti-slip lines 9 not only increase the friction between the apron and the yarn, but also effectively reduce the yarn breakage or quality problems caused by slipping. Especially in the working conditions of high-speed operation and large changes in yarn tension, the tooth-shaped anti-slip lines 9 can significantly improve the transmission efficiency and stability of the apron;
[0034] When the apron is placed on the roller shaft, it will be squeezed by the roller shaft and bent to fit its shape and tightened, so that the apron can fit more closely to the roller shaft and the control roller, thereby more effectively transmitting the tension and movement of the yarn. At the same time, the presence of the tooth-shaped anti-slip lines 9 also enhances the gripping force of the apron in the bent state, further improving the transmission efficiency.
[0035] As Figure 1 and Figure 2 shown, the width of the anti-slip lines 9 is greater than one-third of the total width of the apron, so that the anti-slip lines 9 can better adapt to the transmission path of the yarn.
[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
