Description

Technical Field

[0001] This invention relates to the field of twisting machine equipment technology, specifically to an automatic yarn bobbin feeding device for a twisting machine. Background Technology

[0002] Automatic yarn bobbin feeding equipment for twisting machines is one of the key supporting equipment for the twisting process in the textile industry. Its main function is to quickly feed the full bobbins of yarn after the twisting machine has finished processing, thereby realizing the orderly conveying and centralized collection of full bobbins from the twisting machine spindles, while connecting empty bobbin feeding to ensure the continuous and stable operation of the twisting machine.

[0003] Although existing automatic yarn bobbin feeding equipment for twisting machines can perform yarn bobbin feeding operations, its accuracy in positioning and stability in clamping the yarn bobbins during feeding are still insufficient, which reduces the efficiency of feeding batches of yarn bobbins. Therefore, an automatic yarn bobbin feeding device for twisting machines is needed to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic yarn bobbin feeding device for a twisting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic yarn bobbin feeding device for a twisting machine, comprising a yarn bobbin winding base, three sets of yarn bobbins rotatably arranged at equal intervals on the upper surface of the yarn bobbin winding base, and side plates fixedly arranged on both sides of the yarn bobbin winding base, wherein each set of side plates has a guide groove on its inner end face.

[0006] The guide assembly consists of two sets, both of which are fixedly mounted on the side end face of the side plate. A swing cylinder is fixedly mounted on the inner end face of each of the two sets of guide assemblies. The guide assembly is used for guiding and positioning.

[0007] The feeding assembly is fixedly installed at the power output end of two sets of swing cylinders, and the swing cylinders drive the feeding assembly to rotate and guide it. The feeding assembly is used to clamp and guide the yarn bobbin.

[0008] Specifically, the feeding assembly includes a locking seat, a pen-shaped cylinder fixedly disposed at the center of the upper end face of the locking seat, and a positioning guide fixedly disposed at the power output end of the pen-shaped cylinder. The upper end face of the positioning guide is provided with two sets of linear sliding shafts, and three sets of clamping components are equidistantly disposed at the lower end face of the positioning guide.

[0009] Specifically, the clamping assembly includes a support base, three sets of linear sliding grooves equidistantly opened on the inner end face of the support base, a cover plate sealed and fixedly clamped at the center of the upper end face of the support base, a fixed seat fixedly installed at the center of the upper end face of the cover plate, and a spring guide shaft elastically fixed inside the fixed seat. A stepper motor is provided near the side of the upper end face of the cover plate, and the power output end of the stepper motor drives the driven gear to rotate through the driving gear. A transmission chuck is fixedly installed at the bottom of the driven gear, and three sets of arc-shaped guide grooves are equidistantly opened on the inner end face of the transmission chuck. Three sets of clamping slides are equidistantly clamped on the inner end face of the support base through the linear sliding grooves. A guide shaft is fixedly installed on the upper end face of the clamping slides, and a locking clamp is fixedly installed on the lower end face of the clamping slides.

[0010] Specifically, the three sets of locking clamps are adapted to the guide slide shaft and the arc-shaped guide groove, and the clamping slide block and the straight slide groove, so as to perform centripetal clamping on the yarn bobbin. This makes it convenient for the subsequent locking clamps to adaptively limit the yarn bobbins of different diameters, thus improving the practicality of the equipment.

[0011] Specifically, when the three sets of locking clamps insert and limit the yarn bobbin, the bottom of the spring guide shaft is elastically inserted into the yarn bobbin, and the yarn bobbin is in contact with the bottom of the support bracket. The spring guide shaft can be elastically compressed, which not only facilitates subsequent clamping and positioning, but also improves the convenience of elastically exporting the yarn bobbin.

[0012] Specifically, the guide assembly includes two sets of linear slide rails for support and guide slides that are slidably engaged with the upper part of the two sets of linear slide rails. Rectangular lead screws are rotatably engaged with lead screw guides at the upper and lower parts of the two sets of linear slide rails. A stepper motor is provided at the upper lead screw guide. The power output end of the stepper motor is fixedly connected to the rectangular lead screw through a coupling. A threaded guide is provided at the upper part of the lower end face of the guide slide, and a cylinder holder is provided at the lower part of the lower end face of the guide slide.

[0013] Specifically, the pen-shaped cylinder is adapted to a linear slide shaft and a linear bearing to drive the positioning guide seat to move up and down at the bottom of the locking seat, which can effectively improve the stability of the subsequent up and down movement of the positioning guide seat at the bottom of the locking seat.

[0014] Specifically, the stepper motor 2 is adapted to the rectangular lead screw and threaded guide seat to drive the guide slide, cylinder holder and swing cylinder to move up and down on the upper part of the yarn bobbin winding base. The two sets of swing cylinders drive the locking holder to rotate, which can facilitate the quick and accurate alignment of the yarn bobbin with the external material rack, and improve the stability of the positioning.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This invention is an adjustable automatic yarn bobbin feeding mechanism. Two sets of stepper motors can be connected to the threaded guide seat via rectangular lead screws, thereby adaptively adjusting the height of the locking seat to any value. This facilitates the adaptive positioning of yarn bobbins of different models, effectively improving the adaptability of the equipment for positioning and adjusting different models of yarn bobbins. In addition, three sets of spring guide shafts can be coaxially and elastically positioned with the yarn bobbin, effectively improving the accuracy and stability of the equipment for coaxial positioning of batch yarn bobbins during loading and unloading, thereby improving the efficiency of subsequent loading and unloading of yarn bobbins.

[0017] 2. By setting up a feeding assembly, when feeding three sets of yarn bobbins, the stepper motor can drive the driven gear and the transmission chuck to rotate through the driving gear. The transmission chuck can then drive the three sets of locking clamps to perform centripetal and centrifugal limiting on the yarn bobbins through the limiting of the three sets of arc-shaped guide grooves and guide slide shafts. This can improve the stability of clamping and locking the yarn bobbins, and also improve the adaptability of the equipment to locking yarn bobbins of different radii, thereby improving the practical performance of the equipment.

[0030] The invention will be further described below with reference to the accompanying drawings.

[0031] Example 1

[0032] Please see Figure 1-2 An embodiment of the present invention provides an automatic yarn bobbin feeding device for a twisting machine, comprising a yarn bobbin winding base 6, three sets of yarn bobbins 7 equidistantly rotatably disposed on the upper end face of the yarn bobbin winding base 6, and side plates 1 fixedly disposed on both sides of the yarn bobbin winding base 6, wherein each set of side plates 1 has a guide groove 5 on its inner end face.

[0033] The guide assembly 3 has two sets, and both sets of guide assemblies 3 are fixedly installed on the side end face of the side plate 1. The inner end face of both sets of guide assemblies 3 is fixedly provided with a swing cylinder 4. The guide assembly 3 is used for guiding and positioning.

[0034] The feeding component 2 is fixedly installed at the power output end of the two sets of swing cylinders 4, and the swing cylinders 4 drive the feeding component 2 to rotate and guide by 90 degrees. The feeding component 2 is used to clamp and guide the yarn tube 7.

[0035] like Figure 3 The unloading assembly 2 includes a locking seat 21, a pen-shaped cylinder 23 fixedly disposed at the center of the upper end face of the locking seat 21, and a positioning guide seat 25 fixedly disposed at the power output end of the pen-shaped cylinder 23. The upper end face of the positioning guide seat 25 is provided with two sets of linear sliding shafts 24, and three sets of clamping assemblies 22 are equidistantly disposed on the lower end face of the positioning guide seat 25.

[0036] like Figure 4 , Figure 5 , Figure 6 and Figure 7 The clamping assembly 22 includes a support base 223, three sets of linear slide grooves 2213 equidistantly opened on the inner end face of the support base 223, a cover plate 221 sealed and fixedly clamped to the center of the upper end face of the support base 223, a fixing seat 224 fixedly disposed at the center of the upper end face of the cover plate 221, and a spring guide shaft 222 elastically fixedly disposed inside the fixing seat 224. A stepper motor 2212 is disposed on the upper end face of the cover plate 221 near the side, and the power output end of the stepper motor 2212 is connected to the main... The driven gear 2211 drives the driven gear 226 to rotate. A transmission chuck 225 is fixedly installed at the bottom of the driven gear 226. Three sets of arc-shaped guide grooves 227 are equidistantly opened on the inner end face of the transmission chuck 225. Three sets of clamping slides 2210 are equidistantly engaged on the inner end face of the support base 223 through the straight slide groove 2213. A guide slide shaft 228 is fixedly installed on the upper end face of the clamping slide 2210, and a locking clamp 229 is fixedly installed on the lower end face of the clamping slide 2210.

[0037] like Figure 6 and Figure 7 The three sets of locking clamps 229 are adapted to the arc-shaped guide groove 227 via the guide slide shaft 228 and the clamping slide block 2210 is adapted to the straight slide groove 2213 to perform centripetal clamping on the yarn bobbin 7. Under the centripetal guidance of the arc-shaped guide groove 227, the three sets of locking clamps 229 can perform centripetal displacement, which facilitates the subsequent locking clamps 229 to adaptively limit the yarn bobbin 7 of different diameters and improves the practical performance of the equipment.

[0038] like Figure 5 and Figure 6When the three sets of locking clamps 229 insert and limit the yarn tube 7, the bottom of the spring guide shaft 222 is elastically inserted into the yarn tube 7, and the yarn tube 7 is in contact with the bottom of the support bracket 223. When clamping and positioning the yarn tube 7, the spring guide shaft 222 can first be coaxially positioned with the yarn tube 7, and then the spring guide shaft 222 can be elastically compressed, which can not only facilitate subsequent clamping and positioning, but also improve the convenience of elastically unloading the yarn tube 7.

[0039] like Figure 8 The guide assembly 3 includes two sets of linear slide rails 37 for support and guide slides 31 that are slidably engaged with the upper part of the two sets of linear slide rails 37. Rectangular lead screws 36 are rotatably engaged with lead screw guide seats 34 at the upper and lower parts of the two sets of linear slide rails 37. A stepper motor 32 is provided opposite the upper lead screw guide seat 34. The power output end of the stepper motor 32 is fixedly connected to the rectangular lead screw 36 through a coupling. A threaded guide seat 33 is provided at the upper part of the lower end face of the guide slide 31, and a cylinder holder 35 is provided at the lower part of the lower end face of the guide slide 31.

[0040] like Figure 3 The pen-shaped cylinder 23 is adapted to the linear bearing through the linear slide shaft 24, thereby driving the positioning guide 25 to move up and down at the bottom of the locking seat 21, which can effectively improve the stability of the subsequent up and down movement of the positioning guide 25 at the bottom of the locking seat 21.

[0041] like Figure 8 Stepper motor 32, through rectangular lead screw 36 and threaded guide seat 33, drives guide slide 31, cylinder holder 35 and swing cylinder 4 to move up and down on the yarn winding base 6. The threaded connection between rectangular lead screw 36 and threaded guide seat 33 can effectively improve the accuracy of subsequent cylinder holder 35 and locking holder 21 moving up and down on the yarn winding base 6.

[0042] Furthermore, the two sets of swing cylinders 4 drive the locking seat 21 to rotate 90 degrees, which facilitates the quick and accurate alignment of the yarn bobbin 7 with the external material rack, thus ensuring the stability of the positioning.

[0043] Working principle: When automatically feeding yarn bobbin 7, the operator can start stepper motor 2 32 through the external control module. At this time, stepper motor 2 32 can be connected to the threaded guide seat 33 through the rectangular lead screw 36 at the bottom, thereby driving the guide slide 31 and cylinder holder 35 to move down. This allows the cylinder holder 35 to drive the two sets of swing cylinders 4 and locking holder 21 to move down synchronously. When the support holder 223 is close to yarn bobbin 7, the control module can start stepper motor 1 2212. Stepper motor 1 2212 can drive the driven gear through the drive gear 2211. As wheel 226 rotates, driven gear 226 simultaneously drives transmission chuck 225 and three sets of arc-shaped guide grooves 227 at the bottom to rotate. At this time, the arc-shaped guide grooves 227 can slide and limit with the three sets of guide shafts 228, thereby simultaneously driving the three sets of clamping slides 2210 and locking clamps 229 to perform centrifugal displacement. As the support chuck 223 continues to move downward, the bottom of spring guide shaft 222 is aligned and coaxially inserted with the paper tube inside yarn cylinder 7, while the spring inside spring guide shaft 222 is in a compressed state until the bottom of support chuck 223 is reached. Completely adhering to the upper part of the yarn bobbin 7, at this time, stepper motor 2212 reverses, so that stepper motor 2212 can drive guide slide shaft 228 and locking clamp 229 to clamp and limit the yarn bobbin 7 through transmission chuck 225 and arc guide groove 227. After clamping, stepper motor 32 can drive guide slide 31 to rise through rectangular lead screw 36. When it is raised to the material rack of the outer yarn bobbin 7, the two sets of swing cylinders 4 are started under the action of external solenoid valve and swing 90 degrees, so that locking clamp 21 swings 90 degrees synchronously. At this time, locking clamp 21 is in a position where... The three sets of support brackets 223, yarn bobbins 7 and the material rack are aligned. At the same time, the pen-shaped cylinder 23 is activated. The pen-shaped cylinder 23 can drive the positioning guide seat 25 and the three sets of yarn bobbins 7 to move forward to the opening of the material rack. Then, the stepper motor 2212 drives the drive gear 2211 to reverse. At this time, the spring inside the spring guide shaft 222 releases the pressure, which can push the yarn bobbins 7 into the material rack placement position. Then, as described above, the three sets of locking clamps 229 can clamp the new set of yarn bobbins 7. Then, the yarn bobbins are loaded onto the upper part of the yarn bobbin winding base 6, completing the loading and unloading operation of the yarn bobbins 7.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
