Description

Technical Field

[0001] The utility model belongs to the technical field of textile machinery, in particular to the field of grooved drum box equipment of a false twist texturing machine, and in particular to a guide rod installation assembly for a grooved drum box. Background Art

[0002] The false twist texturing machine is used to perform false twist deformation on the yarn that has been processed by several pre-processing programs, and then wind the obtained yarn on the bobbin to form a cone for transportation and subsequent processing procedures; and the winding of the cone is composed of two mutually perpendicular basic movements, the curling movement and the yarn guiding movement, wherein the curling movement is the movement of the yarn caused by the rotation of the bobbin, and the yarn guiding movement is the reciprocating movement of the yarn following the wire guide along the direction of the bobbin mother line. The yarn guiding movement is mainly realized by the grooved drum box, which mainly includes a grooved drum shaft and a wire guide. Two closed spiral grooves connected end to end are engraved on the circumferential surface of the grooved drum shaft, one is left-handed and the other is right-handed. A transmission part connected to the wire guide is provided in the groove. The wire guide is arranged above the grooved drum shaft, and through the limiting action of the guide rod, it is made to perform linear reciprocating motion during the rotation of the grooved drum shaft.

[0003] With the development of the textile field, technicians have more and more stringent requirements on the overall working performance of false twist texturing machines. When assembling the grooved drum box as a whole or repairing and replacing the parts therein, it is necessary to accurately locate the position of the wire guide and the guide rod so that they can cooperate with the rest of the machinery such as the bobbin. The existing positioning and installation of the guide rod requires the use of a dedicated tool. After the tool is continuously fine-tuned, the wire guide and the guide rod are combined and slidably connected with the pressure plate, and then the pressure plate, guide rod and wire guide are installed together in the grooved drum box using the positioning pin. If multiple grooved drums are assembled or repaired at the same time, In order to install the guide rod and the wire guide box, several workers are required to hold several sets of tooling to position and install the guide rod and the wire guide. The whole installation process is cumbersome and time-consuming, which seriously affects the work efficiency. In the process of using the same tooling for positioning and installing the guide rod and the wire guide for many times, the positioning accuracy of the tooling will be lost due to wear and other reasons. Long-term use will lead to a decrease in its positioning accuracy and the quality of the produced yarn will also decrease. Long-term use of the device will increase the friction between the guide rod and the pressure plate, resulting in friction loss, which will affect the radial positioning of the guide rod, that is, affect the coordination between the wire guide and the other mechanical parts such as the bobbin, and thus affect the production quality of the yarn.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present utility model, it should be noted that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model; the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance. In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] In the prior art, when the groove drum box is assembled as a whole or the guide rod and the wire guide are inspected and replaced, the staff needs to use the dedicated tooling to perform continuous and fine debugging before positioning and installation. If multiple groove drum boxes are assembled or inspected at the same time, several staff members are required to hold several sets of tooling to position and install the guide rod and the wire guide. The whole installation process is cumbersome and time-consuming, which seriously affects the work efficiency. In the process of using the same tooling for positioning and installing the guide rod and the wire guide multiple times, the positioning accuracy of the tooling will be lost due to wear and other reasons. Long-term use will lead to a decrease in its positioning accuracy, and the quality of the produced yarn will also decrease. Long-term use of the device will lead to an increase in friction between the guide rod and the pressure plate, resulting in friction loss, which will further affect the radial positioning of the guide rod, that is, affect the coordination between the wire guide and the bobbin and other mechanical parts, thereby affecting the production quality of the yarn.

[0030] In view of this, the present application focuses on making specific improvements to the structure of the guide rod installation assembly in the groove drum box, and also considers the convenience and stability of the guide rod fixation, and proposes a guide rod installation assembly for the groove drum box, so that the staff can abandon the dependence on tooling during the positioning and installation of the guide rod, thereby achieving the purpose of convenient positioning and installation of the guide rod and improving work efficiency; at the same time, the first pressure plate and the second pressure plate that are arranged in conjunction with each other are used to take into account the stability and wear resistance of the guide rod installation, providing favorable technical improvements for the development of the industry.

[0031] The solution provided by the utility model will be described in detail below with reference to the accompanying drawings.

[0032] In this technical solution, if Figure 1 As shown, a guide rod mounting assembly for a groove drum box includes a box body 1 for carrying the guide rod mounting assembly and having an overall rectangular shape, the box body 1 is divided into two rectangular mounting cavities with completely identical structures and interconnected, and the two mounting cavities are arranged in the same row along their long side directions, wherein one long side portion of each mounting cavity is set as a positioning portion 101, and the other long side portion is set as an auxiliary portion 102.

[0033] It should be understood that the working process of the groove drum box requires the internal wire guide 2 to cooperate with the false twist texturing machine and the bobbin. The yarn processed by the false twist texturing machine is evenly wound onto the bobbin according to a certain winding cross angle by combining the reciprocating motion of the wire guide 2 and the rotational motion of the bobbin. Therefore, there is an assembly position limiting relationship between the wire guide 2 and the bobbin. Because the reciprocating motion process of the wire guide 2 in the prior art depends on the guide rod and the bobbin being installed on the groove drum box through a power mechanism, the above-mentioned position limiting relationship is equivalent to the position positioning relationship between the guide rod and the box body 1 of the groove drum box in this application, and the function of the wire guide 2 can be brought into use by the prior art without explaining its specific structure in detail.

[0034] In this technical solution, if Figure 2 As shown, each installation cavity is provided with a set of guide rod installation components, and the guide rod installation components are used to install the guide rods, and the guide rod installation components include:

[0035] The supporting base is provided with four and is arranged at the four corners of the bottom of the installation cavity at the same time. Each supporting base is provided with a mounting hole 9. Each supporting base is integrally connected with the box body 1. The box body 1 and the four supporting bases all adopt ZL101, wherein the two supporting bases close to the positioning part 101 are both set as the positioning supporting base 3, and the two supporting bases close to the auxiliary part 102 are both set as the auxiliary supporting base 4.

[0036] Specifically, Figure 2-3 As shown, a first limiting groove 301 is provided at the top of each positioning support base 3, the bottom surface of the first limiting groove 301 is a plane, and the first limiting groove 301 includes a first limiting side wall 302, and the first limiting side wall 302 is parallel to the positioning portion 101 and the distance from the positioning portion 101 is 10mm; a second limiting groove 401 is provided at the top of each auxiliary support base 4, and the bottom surface of the second limiting groove 401 is also a plane and is in the same plane as the bottom surface of the first limiting groove 301, the second limiting groove 401 includes a second limiting side wall 402, and the second limiting side wall 402 is parallel to the first limiting side wall 302 and the distance from the first limiting side wall 302 is 48mm. In addition, a first positioning hole 403 is also provided on each auxiliary support base 4.

[0037] On this basis, the four support bases in the present application are used to support a group of guide rods arranged in parallel along the long side of the installation cavity. The diameter of this group of guide rods is 8mm, the material is ZL101, and they are heat treated and the straightness is required to be 0.05. Among them, the guide rod jointly supported by the first limiting grooves 301 on the two positioning support bases 3 is set as the positioning guide rod 5, and the guide rod jointly supported by the second limiting grooves 401 on the two auxiliary support bases 4 is set as the auxiliary guide rod 6. At this point, when the positioning guide rod 5 and the auxiliary guide rod 6 are respectively placed in the corresponding first limiting grooves 301 and the second limiting grooves 401, the center distance between the positioning guide rod 5 and the auxiliary guide rod 6 is 40mm, and the second limiting side wall 402 and the first limiting side wall 302 jointly limit the movement of the positioning guide rod 5 and the auxiliary guide rod 6 away from each other. The specific structure is as follows Figure 3 shown.

[0038] It should be noted that in the present application, the position positioning relationship between a group of guide rods and the box body 1 of the groove drum box is again equivalently converted into: the distance relationship between the first limiting side wall 302 on each positioning support base 3 and the positioning portion 101, that is, based on the above structure, when the positioning guide rod 5 and the auxiliary guide rod 6 are respectively placed in the corresponding first limiting groove 301 and the second limiting groove 401, the installation distance between the positioning guide rod 5, the auxiliary guide rod 6 and the positioning portion 101 of the groove drum box is always determined, and the positioning guide rod 5 is provided with a wire guide 2 through a sliding sleeve of the wire guide mounting seat 201, so the installation position of the wire guide 2 is also determined under the premise that it can perform reciprocating motion.

[0039] Based on the above embodiment, the restrictions on the structure of the positioning support base 3 and the auxiliary support base 4 make it unnecessary to use special tooling to determine the installation distance between the positioning guide rod 5 and the groove drum box positioning part 101 when installing the positioning guide rod 5 and the auxiliary guide rod 6, thereby eliminating the dependence on tooling, making the positioning and installation process more convenient and improving work efficiency.

[0040] In addition, after the positioning guide rod 5 and the auxiliary guide rod 6 are initially positioned and installed, the positioning guide rod 5 and the auxiliary guide rod 6 need to be further fixed by using a first pressing plate 7 and a second pressing plate 8 made of nylon.

[0041] In this technical solution, if Figure 1-5 As shown, the first pressing plate 7 is arranged at a short side portion in the installation cavity and is located above the corresponding positioning support base 3 and the auxiliary support base 4. The first pressing plate 7 includes an integrally arranged first connecting portion 701 and a first working portion.

[0042] Among them, Figure 4-6 As shown, the first working portion is located at one side of the first connecting portion 701, and a first through slot 702 is provided on the first working portion. A first positioning extrusion portion 703 and a first auxiliary extrusion portion 704 are provided on one side of the first through slot 702, wherein the first positioning extrusion portion 703 is provided with a first arc surface 705, and when the positioning guide rod 5 is installed, the first arc surface 705 is in contact with the outer surface of the positioning guide rod 5; the first auxiliary extrusion portion 704 is provided with a first extrusion plane 706, and the first extrusion plane 706 is horizontally arranged. A second arc surface 707 is tangent to one side of the extrusion plane 706. When the auxiliary guide rod 6 is installed, the second arc surface 707 fits the outer surface of the auxiliary guide rod 6. A second extrusion plane 708 is provided on the other side of the first extrusion plane 706, and the second extrusion plane 708 is tangent to the second arc surface 707 in its extended structure. On this basis, the first arc surface 705 and the second arc surface 707 have the same curvature, and the center distance between the first arc surface 705 and the second arc surface 707 is 40.5 mm. Figure 6 shown.

[0043] Similarly, the second pressing plate 8 is arranged at the other short side of the installation cavity, and is located above the corresponding positioning support base 3 and the auxiliary support base 4, as shown in FIG. Figure 7 As shown, the second pressure plate 8 includes an integrally arranged second connecting portion 801, a second working portion and a giveway groove 802, wherein the second working portion and the giveway groove 802 are respectively located on both sides of the second connecting portion, a second through groove 803 is opened on the second working portion, and one side of the second through groove 803 is provided with a second positioning extrusion portion 804 and a second auxiliary extrusion portion 805 which are completely identical in structure to the first positioning extrusion portion 703 and the first auxiliary extrusion portion 704 and correspond to each other.

[0044] In addition, a plurality of cutting holes 10 are formed at the bottom of the first pressing plate 7 and the second pressing plate 8 .

[0045] Based on the above embodiments, when a group of guide rods are positioned and installed, the positioning guide rod 5 is positioned and installed by the cooperation between the first positioning extrusion portion 703 and the first limiting groove 301, and the second positioning extrusion portion 804 and the first limiting groove 301; the auxiliary guide rod 6 is positioned and installed by the cooperation between the first auxiliary extrusion portion 704 and the second limiting groove 401, and the second auxiliary extrusion portion 805 and the second limiting groove 401. In addition, when a group of the guide rods are positioned and installed, the bottom surfaces of the first pressure plate 7 and the second pressure plate 8 are simultaneously in contact with the upper surfaces of the four supporting bases; the provision of the material removal hole 10 reduces the material consumption, and the use of nylon material in combination with the first through groove 702 and the second through groove 803 provides the first working part and the second working part with a structural basis for force deformation.

[0046] It should be noted here that when the first pressing plate 7 and the second pressing plate 8 made of a softer nylon material are used to further tighten the positioning guide rod 5 and the auxiliary guide rod 6, since the center distance between the first arc surface 705 and the second arc surface 707 on the first positioning extrusion portion 703 and the first auxiliary extrusion portion 704 is 40.5 mm, when the first arc surface 705 and the positioning guide rod 5, and the second arc surface 707 and the auxiliary guide rod 6 are respectively fitted and installed, the difference of 0.5 mm in the center distance makes the first arc surface 705 as a whole apply a force toward the bottom surface of the first limiting groove 301 to the positioning guide rod 5, and the second arc surface 707 to the auxiliary guide rod 6. The arc surface 707 is generally used to assist the guide rod 6 in applying force toward the second limiting side wall 402. In order to make the structure complete, the present application sets a first extrusion plane 706 and a second extrusion plane 708 on the second auxiliary extrusion part 805 to cooperate with the second arc surface 707 for limiting to prevent the auxiliary guide rod 6 from popping up. At the same time, since the second working part of the second pressure plate 8 includes a second positioning extrusion part 804 and a second auxiliary extrusion part 805 that are completely identical in structure to the first positioning extrusion part 703 and the first auxiliary extrusion part 704 and correspond to each other, its installation method is the same as the first pressure plate 7, and no further details will be given here.

[0047] On this basis, if Figure 5-7 As shown, the first pressing plate 7 and the second pressing plate 8 are both provided with a second positioning hole 12 which is coaxial with the first positioning hole 403. The first pressing plate 7 and the second pressing plate 8 are positioned when they are installed by the cooperation of the positioning pin with the first positioning hole 403 and the second positioning hole 12. In addition, the first connecting portion 701 of the first pressing plate 7 and the second connecting portion 801 of the second pressing plate 8 are both provided with a countersunk hole 11 which corresponds to the mounting hole 9. After a group of the guide rods are positioned and installed using the first pressing plate 7 and the second pressing plate 8, the first pressing plate 7 and the second pressing plate 8 are fixed to the four supporting bases by the cooperation of screws with the corresponding mounting holes 9 and the countersunk holes 11. At this point, the guide rod mounting assembly provided by the present application provides a structural foundation for the precise positioning and stable installation of the guide rods and the wire guides.

[0048] Specifically, when determining the positional relationship between the wire guide 2 and the bobbin, the utility model manufactures the positioning support base 3 and the auxiliary support base 4 as required, that is, in the present application, the distance between the first limiting side wall 302 and the positioning portion 101 is determined to be 10 mm, and the distance between the second limiting side wall 402 and the first limiting side wall 302 is determined to be 48 mm. In this way, when installing the positioning guide rod 5 and the auxiliary guide rod 6, there is no need to use special tooling to determine the installation distance between the positioning guide rod 5 and the positioning portion 101 of the groove barrel box, thereby eliminating the dependence on tooling, making the positioning and installation process more convenient, and improving work efficiency.

[0049] Then, the first pressing plate 7 and the second pressing plate 8 made of nylon are used to further fix the positioning guide rod 5 and the auxiliary guide rod 6. That is, the first arc surface 705 and the second arc surface 707 are used to apply extrusion force to the positioning guide rod 5 and the auxiliary guide rod 6 respectively by using the difference of 0.5mm center distance. This makes the guide rod installation assembly more firmly position and install the positioning guide rod 5 and the auxiliary guide rod 6, greatly increases friction, reduces friction loss, and improves the stability of the positioning installation of the guide rod and the wire guide 2.

[0050] It should also be clarified in the present invention that the technical solution is only for the position limitation of the lateral distance between the wire guide 2 and the bobbin, and the position limitation of the longitudinal distance is adjusted by the wire guide 2 body, so it will not be explained in detail here.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
