[0026] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0027] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.

[0028] like Figure 1 and Figure 2 As shown, a yarn bobbin limiting device for a staple fiber twisting machine in this embodiment includes a support plate 100 and a left bracket 110 and a right bracket 120 disposed at both ends of the support plate 100. A hinge seat 101 is provided at the left end of the support plate 100. Specifically, the hinge seat 101 is fixedly installed on the front side of the support plate 100 by screws. The left bracket 110 includes a left mounting seat 111 disposed within the hinge seat 101 by a torsion spring. Specifically, the cross-section of the left mounting seat 111 is L-shaped. Under the action of the torsion spring, the left mounting seat 111 is positioned such that one end of the bobbin is positioned as the other end of the bobbin. The side wall is attached to the hinge seat 101, and the other side wall extends outward to form an extension. In its natural state, the torsion spring can drive the extension to be set perpendicular to the support plate 100. The left mounting seat 111 is provided with a movable left support plate 112. The left support plate 112 is set on the extension so that in its natural state, the left support plate 112 is also set perpendicular to the support plate 100. The left support plate 112 is provided with a left support seat 130. Specifically, the left support seat 130 is rotatably mounted on the side of the left support plate 112 facing the right bracket 120 by a bearing.

[0029] The right bracket 120 includes a right mounting seat 121 located at the right end of the support plate 100. The right mounting seat 121 is provided with a movable right support plate 122, and the right support plate 122 is provided with a right support seat 140. Specifically, the right mounting seat 121 and the right support plate 122 are both vertically arranged on the front side of the support plate 100. The right support seat 140 is rotatably mounted on the side of the right support plate 122 facing the left bracket 110. Therefore, the torsion spring is used to drive the left support plate 112 to move towards the right support plate 122, so that the left support seat 130 and the right support seat 140 are arranged opposite to each other. The yarn bobbin can be installed between the left support seat 130 and the right support seat 140. By rotating the left support seat 130 and the right support seat 140, the yarn bobbin can be driven to wind the yarn on the yarn bobbin.

[0030] Specifically, in order to enable the yarn bobbin to be assembled and disassembled between the left support 130 and the right support 140, in this embodiment, combined with Figure 3 As shown, the left mounting base 111 is provided with a notch. The notch allows the left mounting base 111 to rotate within the hinged base 101, so that the extension is moved away from the right bracket 120. This also causes the left bracket 110 to deviate from the right bracket 120, so that the yarn bobbin can be inserted between the two. After the yarn bobbin is inserted, the left mounting base 111 is released. At this time, the torsion spring returns to its original position, which drives the left bracket 110 to return to its original position, so that the left support base 130 and the right support base 140 cooperate to clamp and install the yarn bobbin.

[0031] The right support plate 122 is equipped with an adjustment component for driving the right support base 140 to move.

[0032] In this embodiment, by adjusting the settings of the component, the component can drive the right support 140 to move towards the left support 130 during actual use, so as to adjust the distance between the two, thereby enabling the yarn bobbin limiting device to be applicable to yarn bobbins of different lengths and improving its applicability.

[0033] In this embodiment, the movable arrangement of the left support plate 112 and the right support plate 122 allows the lengths of the left support 110 and the right support 120 to be adjusted. Therefore, by replacing the left support seat 130 and the right support seat 140 on them with larger diameters, the yarn bobbin limiting device can wind the yarn bobbin into a yarn bobbin with a larger diameter, thereby improving the applicability of the yarn bobbin limiting device.

[0034] In actual use, the yarn bobbin limiting device is installed on a short fiber twisting machine to limit the yarn bobbin so that the yarn can be wound on the yarn bobbin.

[0035] In this embodiment, to enable the yarn bobbin to rotate for yarn winding, the staple fiber twisting machine includes a mounting rod 160 for installing the yarn bobbin limiting device, and a winding drive shaft (not shown in the figure) located at the lower front of the mounting rod 160. A mounting base 102 is provided on the back of the support plate 100, and the support plate 100 is mounted on the staple fiber twisting machine via the mounting base 102. Specifically, the mounting rod 160 passes through the mounting base 102, allowing the mounting base 102 to rotate around the mounting rod 160. The assembly base 102 is equipped with a traction member for driving the support plate 100 to rotate. In actual use, under the action of the traction member, the assembly base 102 can rotate around the mounting rod 160, thereby causing the yarn bobbin limiting device to flip so that the outer walls of the left support base 130 and the right support base 140 are in contact with the outer wall of the winding drive shaft. This ensures that the rotation of the winding drive shaft can drive the left support base 130 and the right support base 140 to rotate, thereby causing the yarn bobbin installed therein to rotate so that the yarn is wound on the yarn bobbin.

[0036] Specifically, the outer walls of the left support 130 and the right support 140 extend outward to form abutting rings. The abutting rings abut against the winding drive shaft, and under the action of friction, the winding drive shaft can drive the left support 130 and the right support 140 to rotate.

[0037] In this embodiment, the traction component includes a clamp 210, which is mounted on the mounting rod 160. An extension plate 211 is provided on the clamp 210. A tension spring 220 is provided between the extension plate 211 and the mounting base 102. The tension spring 220 is used to pull the support plate 100 to rotate, thereby preferably pressing the left support base 130 and the right support base 140 onto the winding drive shaft.

[0038] Combination Figure 4 and Figure 5 As shown, in this embodiment, the adjustment assembly includes a connecting cylinder 410 disposed on the right support plate 122. Specifically, the connecting cylinder 410 is integrally formed on the side of the right support plate 122 away from the left bracket 110, and has a threaded hole penetrating the right support plate 122. A screw 150 is threadedly connected to the connecting cylinder 410. The right support seat 140 is rotatably connected to one end of the screw 150. A groove is provided on one side of the right support seat 140, and the end of the screw 150 rotates in the groove through a bearing, thereby realizing the rotatable installation of the right support seat 140 on one end of the screw 150. By turning the screw 150, it can be extended and retracted within the connecting cylinder 410 to realize the movement adjustment of the right support seat 140. In actual use, in order to prevent the screw 150 from rotating and affecting the position of the right support seat 140, a limiting member is provided on the outside of the connecting cylinder 410 to limit the screw 150.

[0039] Specifically, in order to facilitate the rotation of the screw 150 by the operator, a screw cap is provided on the other end of the screw 150.

[0040] In this embodiment, the limiting member includes a threaded cylinder 411 disposed on the outer wall of the connecting cylinder 410, and a countersunk bolt 420 for pressing the screw 150 is internally threaded onto the threaded cylinder 411.

[0041] In this embodiment, a rubber pad is provided at the end of the countersunk bolt 420 that presses against the outer wall of the screw 150. The rubber pad increases the friction between the two, making it difficult for the screw 150 to rotate when the countersunk bolt 420 presses against the outer wall of the screw 150.

[0042] In this embodiment, the right end of the support plate 100 is bent toward its front side to form a right mounting base 121. The right mounting base 121 is perpendicular to the support plate 100. The right mounting base 121 is provided with a first strip groove 1211 along its extension direction. The right support plate 122 is provided with a first stud 401 that passes through the corresponding first strip groove 1211. A first nut for fixing the right support plate 122 is threaded onto the first stud 401.

[0043] In this embodiment, by loosening the first nut, the pressure on the right mounting base 121 is released, which releases the fixation of the right support plate 122, allowing the right support plate 122 to slide along the extension direction of the right mounting base 121, thereby adjusting the length of the right bracket 120. After the adjustment is completed, by tightening the first nut, the right mounting base 121 is pressed, thereby fixing the right support plate 122 so that the right bracket 120 can be used.

[0044] In this embodiment, a second strip groove 1111 is provided on one side wall of the left mounting base 111 along its extension direction, and a second stud 501 is provided on the left support plate 112, which passes through the corresponding second strip groove 1111. A second nut for fixing the left support plate 112 is threaded onto the second stud 501.

[0045] In this embodiment, by loosening the second nut, the compression on the left mounting base 111 is released, and the fixation of the left support plate 112 can be released, allowing the left support plate 112 to slide along the extension direction of the left mounting base 111, thereby adjusting the length of the left bracket 110; after the adjustment is completed, by tightening the second nut, the left mounting base 111 is compressed, thereby fixing the left support plate 112 so that the left bracket 110 can be used.

[0046] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
