Description

Technical Field

[0001] This utility model relates to the technical field of textile machinery, and in particular to a yarn feeding mechanism. Background Technology

[0002] A yarn feeding mechanism is a device used for starting up fabrics during weaving. It feeds steel wire through the needle loops at the tips of the needles on a threading plate, thus completing the starting process without the need for a separate starting yarn, saving yarn.

[0003] The wire feeding mechanism has the functions of feeding and retracting wire to retrieve the steel wire after the initial burring is completed. In existing technology, the wire feeding mechanism typically includes a feeding wheel and a timing belt. The timing belt is fitted onto the feeding wheel and is driven by a motor to rotate, thereby driving the feeding wheel to rotate and wind the steel wire onto it for retraction. Alternatively, when the motor reverses, it drives the feeding wheel to rotate in the opposite direction to feed the steel wire. Simultaneously, the timing belt presses the steel wire tightly between the timing belt and the outer circumference of the feeding wheel. However, because the force applied by the belt to the steel wire cannot be adjusted, if the force is too high, the steel wire is easily worn; if the force is too low, the belt cannot effectively feed and retract the wire. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a wire feeding mechanism that can adjust the pressure of the elastic pressure plate on the steel wire by tightening the fasteners, which can not only feed and draw the wire more smoothly, but also effectively improve the service life of the steel wire.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wire feeding mechanism, including a fixed plate, a wire feeding wheel rotatably connected to the fixed plate, and a motor driving the wire feeding wheel to rotate, and also including a base plate, an inner limiting plate, an outer limiting plate, an elastic pressing plate, and a pressure plate. The pressure plate, the elastic pressing plate, the inner limiting plate, and the base plate are connected from top to bottom to the end face of the wire feeding wheel by fasteners. The outer limiting plate is fixedly connected to the fixed plate and has a central hole. The inner limiting plate is disposed in the central hole and forms an annular wire feeding channel with the outer limiting plate and the base plate. The base plate has a surface a as a support surface for the annular wire feeding channel. The outer end of the inner limiting plate has a surface b, and the outer end of the outer limiting plate has a surface c. The distance between surface a and surface b is less than or equal to the distance between surface a and surface c. The distance between surface a and surface c is less than the outer diameter of the wire. The outer periphery of the elastic pressing plate covers the annular wire feeding channel and presses the wire into the annular wire feeding channel. The pressure of the elastic pressing plate on the wire is adjusted by tightening the fasteners.

[0006] Furthermore, the annular wire feeding channel is provided with a wire feeding port and a wire drawing port. The fixed plate or base plate is provided with a raised part corresponding to the positions of the wire feeding port and the wire drawing port. The raised part is provided with a surface d. The distance between surface d and surface a is greater than the distance between surface c and surface a. The surface d supports the elastic pressing plate and lifts the elastic pressing plate to a set height.

[0007] Furthermore, the raised portion is a bearing rotatably connected to the fixed plate or the base plate.

[0008] Furthermore, the outer periphery of the elastic pressing disc is provided with connecting holes, and the connecting holes are provided in multiple ways and are circumferentially distributed on the outer periphery of the elastic pressing disc.

[0009] Furthermore, the connecting hole is strip-shaped and located in the area of ​​the corresponding annular wire feeding channel.

[0010] Furthermore, the pressure plate is disposed within the inner circle of the annular wire feeding channel.

[0011] Furthermore, the fixed plate is provided with a rotating shaft, and an integral component consisting of a wire feeding wheel, a base plate, an inner limiting plate, an outer limiting plate, an elastic pressing plate, and a pressing plate is rotatably connected to the rotating shaft.

[0013] Furthermore, the output end of the motor is provided with drive teeth, which mesh with the toothed part of the wire feeding wheel for transmission.

[0014] Furthermore, both the inner limiting disk and the central hole are circular structures, with the diameter of the central hole being larger than the outer diameter of the inner limiting disk.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] like Figures 1-6 As shown, a wire feeding mechanism includes a fixed plate 10, a wire feeding wheel 20 rotatably connected to the fixed plate 10, and a motor 30 that drives the wire feeding wheel 20 to rotate. The motor 30 is installed on the side of the fixed plate 10 away from the wire feeding wheel 20.

[0027] The wire feeding mechanism also includes a base plate 40, an inner limit plate 50, an outer limit plate 60, an elastic wire pressing plate 70, and a pressure plate 80. The pressure plate 80, the elastic wire pressing plate 70, the inner limit plate 50, and the base plate 40 are connected from top to bottom to the end face of the wire feeding wheel 20 by fasteners. That is to say, the pressure plate 80, the elastic wire pressing plate 70, the inner limit plate 50, the base plate 40, and the wire feeding wheel 20 are connected as a whole by fasteners. When the motor 30 drives the wire feeding wheel 20 to rotate, it can drive the pressure plate 80, the elastic wire pressing plate 70, the inner limit plate 50, and the base plate 40 to rotate synchronously.

[0028] The outer limiting plate 60 is fixedly connected to the fixing plate 10. The outer limiting plate 60 has a central hole and is located at the upper end of the base plate 40. The inner limiting plate 50 is disposed in the central hole and forms an annular wire feeding channel 90 with the outer limiting plate 60 and the base plate 40. Specifically, the inner limiting plate 50 and the central hole are both circular structures, and the diameter of the central hole is larger than the outer diameter of the inner limiting plate 50.

[0029] The base plate 40 has a surface a41 that serves as a support surface for the annular wire feeding channel 90. The outer end of the inner limiting plate 50 has a surface b51, and the outer end of the outer limiting plate 60 has a surface c61. The distance between surface a41 and surface b51 is less than or equal to the distance between surface a41 and surface c61. The distance between surface a41 and surface c61 is less than the outer diameter of the steel wire 120. The outer periphery of the elastic pressing plate 70 covers the annular wire feeding channel 90 and presses the steel wire 120 into the annular wire feeding channel 90. The pressure of the elastic pressing plate 70 on the steel wire 120 is adjusted by tightening the fasteners. Since the distance between surface a41 and surface c61 is less than the outer diameter of the steel wire 120, that is, the steel wire 120 extends out of the annular wire feeding channel 90 and pushes the outer periphery of the elastic pressing plate 70 outward. Under its own elastic force, the elastic pressing plate 70 firmly presses the steel wire 120 into the annular wire feeding channel 90, thereby enabling smoother and more effective wire feeding and drawing.

[0030] In some embodiments, the annular wire feeding channel 90 is provided with a wire feeding port and a wire drawing port. The fixing plate 10 or the base plate 40 is provided with a raised part 11 corresponding to the positions of the wire feeding port and the wire drawing port. The raised part 11 is provided with a surface d. The distance between surface d and surface a41 is greater than the distance between surface c61 and surface a41. The surface d supports the elastic pressing plate 70 and raises the elastic pressing plate 70 to a set height. Specifically, the distance between surface d and surface a41 is 0.1mm-0.5mm larger than the distance between surface c61 and surface a41, preferably 0.2mm. With the above arrangement, it is convenient for the steel wire 120 to enter the annular wire feeding channel 90 from the wire feeding port. Similarly, it is also convenient for the steel wire 120 located in the annular wire feeding channel 90 to be drawn out through the wire drawing port.

[0031] In some embodiments, the raised portion 11 is a bearing rotatably connected to the fixed plate 10 or the base plate 40. Specifically, the elastic pressure plate 70 is pressed against the outer ring of the bearing, and the outer ring of the bearing is rotatably connected to the inner ring of the bearing, so as to reduce the friction between the elastic pressure plate and the raised portion 11 when the elastic pressure plate rotates, thereby effectively reducing the wear of the elastic pressure plate 70 when it rotates.

[0032] In some embodiments, the elastic pressing disc 70 has multiple connecting holes 71 distributed circumferentially around its outer periphery. The connecting holes 71 enhance the elastic deformation capability of the elastic pressing disc 70. Specifically, the connecting holes 71 are strip-shaped and located in the region corresponding to the annular wire feeding channel 90.

[0033] In some embodiments, the pressure plate 80 is disposed within the inner circle of the annular wire feeding channel 90, that is, the pressure plate 80 is fixedly connected to the elastic pressure plate 70 within the inner circle of the annular wire feeding channel 90, so as to avoid the pressure plate 80 interfering with the steel wire 120 pressed in the annular wire feeding channel 90.

[0034] In some embodiments, the fixed plate 10 is provided with a rotating shaft 12, and an integral component consisting of a wire feeding wheel 20, a base plate 40, an inner limiting plate 50, an outer limiting plate 60, an elastic pressing plate 70, and a pressing plate 80 is rotatably connected to the rotating shaft 12.

[0035] In some embodiments, the fixing plate 10 is provided with a fixing block 100 and a guide tube 110. The fixing block 100 is fixedly connected to the fixing plate 10, and the guide tube 110 is detachably fixed to the fixing block 100. Specifically, the fixing block 100 is provided with a groove for installing the guide tube 110 and a positioning block detachably connected to the fixing block 100 for fixing the guide tube 110 in the groove. The guide tube 110 includes a wire feeding tube for guiding wire feeding and a wire drawing tube for guiding wire drawing.

[0036] In some embodiments, the output end of the motor 30 is provided with a drive tooth 31, which meshes with the tooth body portion 21 of the wire feeding wheel 20 for transmission, and the number of teeth of the drive tooth 31 is less than the number of teeth of the wire feeding wheel 20. This arrangement is not only used to provide driving force, but also to play a deceleration function.

[0037] In summary, this utility model has the following beneficial effects: The wire feeding mechanism of this utility model can adjust the pressure of the elastic pressure plate 70 on the steel wire 120 by tightening the fasteners, which can not only feed and draw the wire more smoothly, but also effectively improve the service life of the steel wire 120.

[0038] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
