Description

Technical Field

[0001] The utility model relates to the technical field of draw frames, and specifically relates to a draw frame guide rod structure. Background Art

[0002] A draw frame is a textile machinery equipment, mainly used for drafting, doubling and twisting the carded sliver to make yarn with a certain thickness and structure. At present, in the process of combining multiple slivers into one in a draw frame, mainly through the guide rod 1, the slivers in the yarn bobbin 6 are respectively guided into the gaps formed by a plurality of cylindrical rods 7 on the front side of the draw frame.

[0003] At present, our factory uses the Rieter draw frame D26C, and the standard configuration is six doublings. The weight stability of the product after doubling is relatively low. To further improve the weight stability of the roving, the weight stability of the last draw frame can be improved by adding one more doubling, that is, seven doublings production. However, when the Rieter draw frame D26C is in use at present, the yarn bobbins 6 loaded with slivers are in a V-shaped state from the cylindrical rods 7 to the tail end of the draw frame. Adding one more doubling requires adding one more guide rod 1. To prevent the slivers from being entangled during the traction of the guide rod 1, it is best to set the added guide rod 1 at a position close to the cylindrical rod 7, and the position of the original guide rod 1 needs to be adjusted to design the yarn bobbins 6 loaded with slivers in an inverted V-shaped state. Since the guide rod 1 of the current Rieter draw frame needs to be disassembled and adjusted, and the level also needs to be adjusted, the operation is relatively difficult. Therefore, a draw frame guide rod structure is provided. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a draw frame guide rod structure that is convenient for adjusting the guide rod.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] See Figures 1-4 .

[0027] The guide rod structure of the draw frame of the present utility model includes:

[0028] An adjusting mechanism 2, at least including a connecting assembly 201 for fixing on a support rod 3 and a fixing assembly 202 arranged on the connecting assembly 201;

[0029] A guide rod 1, rotatably arranged on the connecting assembly 201 along the circumferential direction of the support rod 3 and capable of being horizontally fixed on both sides of the support rod 3 by the fixing assembly 202.

[0030] The guide rod structure of the draw frame of the present utility model is connected to the support rod 3 through the connecting assembly 201, and the guide rod 1 is rotationally adjusted on the connecting assembly 201 and fixed by the fixing assembly 202 after rotation, so that the adjustment operation of the guide rod 1 is convenient, and the fixing is realized by designing the fixing assembly 202 at the position where the guide rod 1 is in a horizontal state, which also facilitates the leveling operation of the guide rod 1.

[0031] In this embodiment, refer to Figure 3 and 4 . The fixing component 202 includes two fixing rings 2021 that are spaced along the direction of the support rod 3 and have trajectories of moving closer to and away from each other. The two fixing rings 2021 are sleeved on the support rod 3, and fixing blocks 203 are respectively arranged on both sides of each fixing ring 2021, and each fixing block 203 has a slot A.

[0032] The guide rod 1 can be fixedly connected to the slot A when the two fixing rings 2021 move closer to each other and be released when the two fixing rings 2021 move away from each other. With such a design, the fixing or not of the guide rod 1 can be achieved by adjusting the two fixing rings 2021 to move away from and closer to each other. The structure is simple and easy to operate. And in this embodiment, the position of the slot A is set when the guide rod 1 is in a horizontal state on both sides of the fixing ring 2021.

[0033] In this embodiment, refer to Figure 4 . The connecting component 201 includes a collar 2011 fixed on the support rod 3 and two connecting rings 2012 sleeved on both ends of the collar 2011. And a connecting plate 2013 is arranged at an interval between each connecting ring 2012 and the collar 2011, and a plurality of springs 2014 are further arranged on each connecting plate 2013.

[0034] The two fixing rings 2021 are respectively sleeved on both ends of the collar 2011 and are connected to the springs 2014 in the intervals between the connecting rings 2012 and the collar 2011. With such a design, through the connection of the springs 2014, the mutual separation and approach of the two fixing rings 2021 are realized. The structure is simple and easy to operate. At the same time, the two fixing rings 2021 are sleeved on the collar 2011 to maintain the movement stability when moving away from and closer to each other.

[0035] In this embodiment, refer to Figure 3 and 4, 5. The fixing block 203 includes two interconnected triangular clamping portions 2031, and a triangular slot A is formed between the two clamping portions 2031. Triangular clamping blocks 5 that are engaged with the slot A are respectively provided on both sides of the end of the guiding rod 1, and the ends of the clamping blocks 5 corresponding to the engagement with the slot A are designed with rounded corners. With this design, the guiding rod 1 can be clamped and fixed from the cross-sectional diameter direction of the guiding rod 1 through the cooperation of the slot A of the two fixing rings 2021 and the clamping blocks 5. When it is necessary to release the fixation, only by moving the guiding rod 1 to rotate it along the collar 2011, the clamping portion 2031 is squeezed, and due to the structural design characteristics of the clamping block 5 and the slot A, the two fixing rings 2021 are driven to move away from each other to achieve release. The fixing process is the same in principle, which facilitates the adjustment and fixing process of the guiding rod 1. In this embodiment, the slots A of the two fixing rings 2021 can be symmetrically arranged.

[0036] In this embodiment, referring to Figure 3 , the diameter of the end of the guiding rod 1 corresponding to the clamping block 5 is larger than the interval between the two connecting rings 2012. With this design, the connecting ring 2012 restricts the clamping block 5 along the length direction of the guiding rod 1 to prevent the clamping block 5 from detaching.

[0037] In this embodiment, referring to Figure 2 , further comprising:

[0038] A bell mouth 4 is provided on the guiding rod 1 for restricting the position of the fiber strip on the guiding rod 1 and guiding the fiber strip. With this design, the guiding path of the fiber strip is fixed, preventing the fiber strip from having a large displacement on the guiding rod 1 when the guiding rod 1 guides the fiber strip, which reduces the quality of drawing.

[0039] In this embodiment, referring to Figure 2 , the guiding rod 1 includes a rod body 101, a threaded rod 102 rotatably arranged in the rod body 101, a driving block 103 rotatably arranged at one end of the rod body 101 away from the adjusting mechanism 2 and connected to the threaded rod 102, and a connecting block 104 slidably arranged on the guiding rod 1 and threadedly connected to the threaded rod 102. The bell mouth 4 is detachably connected to the connecting block 104. With this design, by rotating the driving block 103, the movement of the connecting block 104 can be achieved, and thus the movement of the bell mouth 4 can be achieved, facilitating the adjustment of the position of the bell mouth 4. When adjusting the position of the yarn bobbin 6, the position of the bell mouth 4 can be correspondingly adjusted. In this embodiment, the detachable connection between the bell mouth 4 and the connecting block 104 can be achieved by screws. When adjusting the position of the guiding rod 1, the bell mouth 4 can be adjusted in both forward and reverse directions. The bell mouth 4 and the connecting block 104 can also be provided with a damped rotational connection, which is more convenient for adjustment.
