Description

Technical Field

[0001] This utility model relates to the field of roving frame textile technology, and in particular to a roving frame yarn changing mechanism. Background Technology

[0002] The roving frame plays a crucial role in textile production. It processes fibers into rovings, providing essential raw material support for subsequent spinning processes.

[0003] During the spinning process on a roving frame, when the roving on the roving tube is spun out or nearly spun out, a new roving tube needs to be replaced to continue spinning. If the roving tube is not replaced in time, the roving frame will not be able to spin normally, affecting production efficiency.

[0004] Based on the above situation, most yarn changing operations on roving frames still require manual intervention, which not only increases the labor intensity of workers but also reduces the efficiency of yarn changing. Utility Model Content

[0005] The purpose of this invention is to provide a yarn changing mechanism for a roving frame that meets the needs of automated yarn changing and improves efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a yarn changing mechanism for a roving frame, comprising a yarn cylinder, a yarn changing component, and a positioning component;

[0007] The yarn changing assembly and the positioning assembly are respectively located at the upper and lower ends of the yarn bobbin. The yarn bobbin is connected to the roving frame conveyor line through the yarn changing assembly, so that the yarn bobbin can be connected to the positioning assembly for yarn winding and subsequent yarn changing and separation.

[0008] The yarn tube has a yarn changing hole at the top, and the yarn tube is detachably connected to the yarn changing component through the yarn changing hole.

[0009] A further feature of this invention is that the yarn changing assembly includes an installation cylinder and an electric suction cup embedded and fixed at the bottom of the installation cylinder.

[0010] By adopting the above technical solution, the electric suction cup can generate magnetic force to attract the yarn bobbin and drive it to move.

[0011] A further feature of this invention is that a mating plate is fixedly provided on the surface of the yarn changing hole, and the mating plate is magnetically connected to the bottom end of the electric suction cup.

[0012] By adopting the above technical solution, the mounting cylinder can be moved and separated.

[0013] A further feature of this invention is that the top end of the mounting cylinder is fixedly connected to the support column.

[0014] By adopting the above technical solution, the movement and placement of the yarn bobbin can be accomplished by switching the electric suction cup on and off.

[0015] A further feature of this invention is that the yarn tube has an open cavity at the bottom, and a ramp ring is provided at the bottom edge of the cavity.

[0016] By adopting the above technical solution, it is convenient to insert the yarn bobbin and the positioning component.

[0017] A further feature of this invention is that the positioning component includes a second support and a mounting column whose bottom end is fixedly connected to the second support, with the outer side of the mounting column coaxially inserted into the cavity.

[0018] By adopting the above technical solution, the yarn can be placed on the mounting column for operation when the yarn is wound on the surface of the yarn tube.

[0019] A further feature of this invention is that the mounting column has a mounting hole, and a fixing mechanism is provided in the mounting hole.

[0020] By adopting the above technical solution, circumferential rotation will not occur during yarn winding, thus affecting the yarn winding efficiency.

[0021] A further feature of this invention is that the fixing mechanism includes a fixing block and a spring that slide along the mounting hole, with the inner and outer ends of the spring respectively fixed to the mounting hole and the fixing block.

[0022] By adopting the above technical solution, the fixing block can be extended and retracted along the inside of the mounting hole by the force of the spring.

[0023] A further feature of this invention is that an anti-slip strip for contacting the cavity is fixed on the side of the fixing block away from the spring.

[0024] By adopting the above technical solution, the anti-slip strip is a straight line extending vertically to improve the contact friction with the cavity.

[0025] A further feature of this invention is that a locator is embedded in the top surface of the mounting column, and a positioning rod that cooperates with the locator is provided in the cavity.

[0026] By adopting the above technical solution, when the yarn bobbin and the mounting column are coaxial, information can be obtained through the positioner.

[0027] The beneficial effects of this utility model are:

[0028] This system provides an automatic yarn changing method to replace manual yarn changing. By connecting the yarn changing component to the yarn feeding line of the roving frame, the system works in conjunction with an electric suction cup via a mating plate on the yarn bobbin. The electric suction cup then moves the yarn bobbin to the support for winding and subsequent separation and conveying, eliminating the need for manual intervention and improving efficiency. Furthermore, after the yarn bobbin is placed, the cooperation of the fixing block and spring reduces the circumferential rotational force of the yarn bobbin, improving the stability of the yarn loading process without affecting the smooth operation of the entire yarn changing process.

[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] This utility model embodiment specifically provides a yarn changing mechanism for a roving frame. Please refer to... Figures 1-4 It includes a yarn tube 1, a yarn changing assembly 2, and a positioning assembly 3.

[0037] The yarn changing component 2 and the positioning component 3 are respectively located at the upper and lower ends of the yarn tube 1. The yarn tube 1 is connected to the roving frame conveyor line through the yarn changing component 2, so that the yarn tube 1 can connect with the positioning component 3 for yarn winding and subsequent yarn changing and separation.

[0038] Specifically, the yarn tube 1 has a yarn changing hole 11 at the top. The yarn tube 1 is detachably connected to the yarn changing assembly 2 through the yarn changing hole 11, so that when the yarn changing assembly 2 is installed on the roving frame conveyor line, the yarn tube 1 can be quickly installed through the yarn changing assembly 2.

[0039] The yarn changing assembly 2 includes a mounting cylinder 21 and an electric suction cup 22 embedded and fixed at the bottom of the mounting cylinder 21. The electric suction cup 22 can generate magnetic force to attract the yarn cylinder 1 and drive the yarn cylinder 1 to move.

[0040] During implementation, a mating plate 12 is fixedly installed on the surface of the yarn changing hole 11. The mating plate 12 is magnetically connected to the bottom end of the electric suction cup 22. The mating plate 12 is made of iron. When the electric suction cup 22 is energized, the electric suction cup 22 can adsorb the mating plate 12, or when the electric suction cup 22 is de-energized, the adsorption of the mating plate 12 can be canceled, thereby moving and separating the mounting cylinder 21.

[0041] The top of the mounting cylinder 21 is fixedly connected to the support column 23. The mounting cylinder 21 is fixed to the roving frame conveyor line through the support column 23. This method is a mature existing technology. The purpose of this technical solution is to provide a quick way to change yarn on the yarn cylinder 1. Therefore, the installation method of the yarn changing component 2 and the positioning component 3 on the roving frame will not be described in detail here.

[0042] Once the installation cylinder 21 is intelligently controlled by the conveyor line, the movement and placement of the yarn cylinder 1 can be completed by switching the electric suction cup 22 on and off, thus replacing manual labor and saving time and effort.

[0043] Furthermore, the yarn tube 1 has an open cavity inside, and a ramp ring 14 is provided on the bottom edge of the cavity to facilitate the insertion of the yarn tube 1 and the positioning component 3.

[0044] Specifically, the positioning component 3 includes a second support 31 and a mounting post 32 whose bottom end is fixedly connected to the second support 31. The bottom surface of the second support 31 is fixed to the roving frame, and the outer side of the mounting post 32 is coaxially inserted into the cavity, so that when the yarn is wound on the surface of the yarn tube 1, it can be placed on the mounting post 32 for operation.

[0045] The mounting column 32 has a mounting hole 34, and a fixing mechanism is provided in the mounting hole 34. The fixing mechanism applies force to the yarn tube 1 so that the yarn tube 1 can be kept fixed in the circumferential direction, so that it will not rotate in the circumferential direction during yarn winding and affect the yarn winding efficiency.

[0046] Specifically, the fixing mechanism includes a fixing block 35 that slides along the mounting hole 34 and a spring 36. The inner and outer ends of the spring 36 are fixed to the mounting hole 34 and the fixing block 35 respectively, so that the fixing block 35 can move telescopically along the inside of the mounting hole 34 by the force of the spring 36.

[0047] In normal conditions, the yarn tube 1 and the mounting post 32 are separate. Under the action of the spring 36, the outer end of the fixing block 35 is higher than the side of the mounting post 32. When the yarn tube 1 is inserted vertically downward into the mounting post 32, the upper part of the fixing block 32 will be retracted into the mounting hole 34 by the force of the ramp ring 14, and then pressed against the inner wall of the cavity by the force of the spring 36.

[0048] In practice, a non-slip strip 37 for contacting the cavity is fixed on the side of the fixed block 35 away from the spring 36. The non-slip strip 37 is a straight line extending vertically to improve the contact friction with the cavity.

[0049] Furthermore, as another feasible implementation of this technical solution, a locator 33 is embedded in the top surface of the mounting column 32, and a positioning rod 15 that cooperates with the locator 33 is provided in the cavity. The type of the locator 33 can be an infrared sensor. The positioning rod 15 is higher than the top surface of the cavity and is coaxial with the cavity so as to cooperate with the locator 33. When the yarn bobbin 1 is coaxial with the mounting column 32, information can be obtained through the locator 33, thereby facilitating the roving frame controller to control the yarn bobbin 1 to move down for installation.

[0050] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
