[0015] Furthermore, a method for using a screw-on metal bottle mouth thread manufacturing device, a screw-on metal bottle mouth thread manufacturing device, the method comprising the following steps:

[0016] S1: Place bottles: First, place the bottles that need to be threaded into the feed rack;

[0017] S2: Push the bottle: Then start the motor, which will drive the lower knurling shaft to rotate when working, then start the feeding rack, which will bring a bottle in through the sliding rack and slide forward when working, then start the electric push rod 2, which will insert the bottle mouth into the side wall of the lower knurling shaft through the rotating disk when working;

[0018] S3: Rotational rolling: Then the electric push rod 3 is started. When working, the electric push rod 3 will drive the upper knurling shaft to move downward through the sliding plate. When the upper knurling shaft moves downward, it will roll the bottle mouth inserted on the lower knurling shaft to achieve the purpose of making threads on the bottle mouth.

[0019] The present invention has the following beneficial effects:

[0020] 1. In the present invention, when the electric push rod 2 pushes the bottle through the rotating disk, the bottle mouth will squeeze the sliding ring, and after the sliding ring is squeezed, it will drive the long rod to move backward through multiple L plates. When the long rod moves backward, it will push the arc plate to slide through the connecting rod 1. When the arc plate slides after being pushed by the connecting rod 1, the multiple arc plates will expand outward under the restriction of the connecting rod 2. When the arc plate slides, it will expand outward from the inside of the bottle body. When the multiple arc plates expand outward, they will expand on the inside of the bottle body. The inner wall exerts an outward supporting force on the bottle and plays a role in positioning the bottle, reducing the eccentricity of the bottle mouth on the lower rolling axis, which may lead to uneven depth or pitch of the rolled threads, thereby affecting the matching accuracy during subsequent assembly. At the same time, when multiple arc plates expand outward, they can also play a certain fixing role on the bottle, reduce the shaking or deviation of the bottle during the rolling process, thereby ensuring the stability of the rolling process, reducing the problems of irregular thread shape caused by the shaking of the bottle, and improving the processing efficiency.

[0021] 2. According to the present invention, when the multiple long rods are pulled by the L-plate to slide, the sliding of the long rods will be separated from the protrusions of the elastic plate, and the elastic plate will gradually rebound and reset under the sliding of the long rods. When the elastic plate is reset, a lateral thrust will be generated on the side wall of the sliding frame 2 to push the sliding frame 2 to slide in the direction of the lower knurling axis. When the sliding frame 2 slides, it will drive the spring rod to slide in the rectangular through groove on the connecting frame through the connecting frame and the rotating ring. When the spring rod slides, it will drive the C-shaped frame to slide synchronously. When the C-shaped frame slides with the sliding of the spring rod, the C-shaped frame will be guided by the trapezoidal groove on the hollow cylinder to stretch the spring rod and be between the lower knurling axis and the bottle mouth. Then, when the C-shaped frame slides between the lower knurling axis and the bottle mouth, the side wall of the movable plate will be squeezed by the threaded groove on the hollow cylinder to When the movable plate rotates, it will squeeze the elliptical elastic plate through the cam on the top. After the elliptical elastic plate is squeezed, the middle part of the elliptical elastic plate will bulge outward. When the elliptical elastic plate is deformed, it will push on one side of the bottle mouth through the multiple balls on the top and play a certain supporting role. Then, when the rotation of the lower knurling shaft drives the upper knurling shaft to rotate through the friction between the bottle and the upper knurling shaft, the rotation of the upper knurling shaft will generate a lateral squeezing force on the elliptical elastic plate when rolling the bottle, which can resist the deformation of the bottle mouth due to the gap between the bottle mouth and the lower knurling shaft during the rolling process, resulting in the uneven pressure between the upper knurling shaft and the lower knurling shaft. Further, it can reduce the excessive flow of the bottle mouth material in a certain direction during rolling, thereby reducing the possibility of wrinkles.

[0022] 3. According to the present invention, when the rotation of the movable plate squeezes the elliptical elastic plate, the middle part of the elliptical elastic plate will bulge outward after being squeezed, and when the elliptical elastic plate is deformed, its bottom will squeeze the spring frame, and the spring frame will drive the roller to slide downward after being squeezed, and when the roller slides downward, its surface will contact the surface of the lower knurling shaft, so that the sliding friction between the C-shaped frame and the lower knurling shaft can be converted into rolling friction under the lateral squeezing force of the C-shaped frame and the elliptical elastic plate when the upper knurling shaft rotates, so that the friction between the C-shaped frame and the lower knurling shaft can be reduced, so as to ensure the fluidity of the C-shaped frame when sliding, reduce the situation of stagnation between the C-shaped frame and the lower knurling shaft due to excessive friction, reduce the accuracy of bottle mouth rolling due to the sliding stagnation of the C-shaped frame, and improve the rolling efficiency.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] A method for using a screw-on metal bottle mouth thread manufacturing device, the screw-on metal bottle mouth thread manufacturing device, the method comprising the following steps:

[0049] S1: placing bottles: firstly placing bottles to be threaded into the feeding rack 101;

[0050] S2: Pushing the bottle: Then start the motor 202, which will drive the lower knurling shaft 301 to rotate when working, then start the feeding rack 101, which will bring a bottle in through the sliding rack 102 and slide forward when working, then start the second electric push rod 104, which will insert the bottle mouth into the side wall of the lower knurling shaft 301 through the rotating disk 105 when working;

[0051] S3: Rotation and rolling: Then the electric push rod 3 203 is started. When working, the electric push rod 3 203 will drive the upper knurling shaft 205 to move downward through the sliding plate 204. When the upper knurling shaft 205 moves downward, it will roll the bottle mouth inserted on the lower knurling shaft 301 to achieve the purpose of making threads on the bottle mouth.

[0052] When in use, first place the bottle that needs to be threaded into the feed rack 101, then start the motor 202, which will drive the lower knurling shaft 301 to rotate when working, then start the feed rack 101, and the feed rack 101 will bring in a bottle through the sliding rack 102 to slide forward when working, then start the electric push rod 204, and the electric push rod 204 will insert the bottle mouth into the side wall of the lower knurling shaft 301 through the rotating disk 105 when working, then start the electric push rod 3 203, and the electric push rod 3 203 will drive the upper knurling shaft 205 to move downward through the sliding plate 204 when working, and the upper knurling shaft 205 will roll the bottle mouth inserted on the lower knurling shaft 301 when moving downward, so as to achieve the purpose of making threads on the bottle mouth.

[0053] When the electric push rod 2 104 pushes the bottle through the rotating disk 105, the bottle mouth will squeeze the sliding ring 303. After being squeezed, the sliding ring 303 will drive the long rod 305 to move backward through the multiple L plates 304. When the long rod 305 moves backward, it will push the arc plate 307 to slide through the connecting rod 1 306. When the arc plate 307 slides after being pushed by the connecting rod 1 306, the multiple arc plates 307 will expand and slide outward under the restriction of the connecting rod 2 308. When the arc plate 307 slides, it will expand outward inside the bottle body. When the arc-shaped plates 307 expand outward, they will exert an outward supporting force on the inner wall of the bottle body to support the bottle, and play a role in positioning the bottle, thereby reducing the eccentricity of the bottle mouth on the lower knurling shaft 301, which will lead to uneven depth or uneven pitch of the rolled threads, thereby affecting the matching accuracy during subsequent assembly. At the same time, when multiple arc-shaped plates 307 expand outward, they can also play a certain fixing role on the bottle, reduce the shaking or deviation of the bottle during the rotation and rolling process, thereby ensuring the stability of the rolling process, reducing the problems of irregular thread shape caused by the shaking of the bottle, and improving the processing efficiency.

[0054] When the multiple long rods 305 slide under the pull of the L plate 304, the sliding of the long rods 305 will be separated from the protrusions of the elastic plate 401, and the elastic plate 401 will gradually rebound and reset under the sliding of the long rods 305. When the elastic plate 401 resets, it will generate a lateral thrust on the side wall of the sliding frame 402 to push the sliding frame 402 to slide in the direction of the knurling shaft 301. When the sliding frame 402 slides, it will pass through the connecting frame 403 and the rotating ring 50 1 drives the spring rod 502 to slide in the rectangular groove on the connecting frame 403. When the spring rod 502 slides, it drives the C-shaped frame 503 to slide synchronously. When the C-shaped frame 503 slides along with the sliding of the spring rod 502, the C-shaped frame 503 is guided by the trapezoidal groove on the hollow cylinder 404 to stretch the spring rod 502 and is located between the lower knurling shaft 301 and the bottle mouth. Then, when the C-shaped frame 503 slides between the lower knurling shaft 301 and the bottle mouth, the side wall of the movable plate 504 When the bottle is rolled, the upper rolling shaft 205 is rotated to generate a lateral squeezing force on the elliptical elastic plate 601, which can resist the deformation of the bottle mouth due to the gap between the bottle mouth and the lower rolling shaft 301, thereby reducing the excessive flow of the bottle mouth material in a certain direction during rolling, thereby reducing the possibility of wrinkles.

[0055] When the elliptical elastic plate 601 is subjected to the lateral extrusion force when the upper knurled shaft 205 rotates, the elliptical elastic plate 601 will slide and reset in the threaded groove on the hollow cylinder 404 through the C-shaped frame 503 and the spring rod 502. When the movable plate 504 rotates to squeeze the elliptical elastic plate 601, the middle part of the elliptical elastic plate 601 will bulge outward after being squeezed. When the elliptical elastic plate 601 is deformed, its bottom will squeeze the spring frame 603. After being squeezed, the spring frame 603 will drive the roller 604 to slide downward. When the roller 604 slides downward, its surface will contact with the lower roller. The surface of the knurling shaft 301 can be contacted by the C-shaped frame 503 and the elliptical elastic plate 601, and then the sliding friction between the C-shaped frame 503 and the lower knurling shaft 301 can be converted into rolling friction under the lateral extrusion force when the upper knurling shaft 205 rotates, thereby reducing the friction between the C-shaped frame 503 and the lower knurling shaft 301, thereby ensuring the fluidity of the C-shaped frame 503 when sliding, reducing the jamming between the C-shaped frame 503 and the lower knurling shaft 301 due to excessive friction, reducing the accuracy of bottle mouth rolling due to the sliding jam of the C-shaped frame 503, and improving the rolling efficiency.
