[0008] With the above technical solution, when in use, the bottle is placed inside the groove on the top side of the base. Then, under the action of the drive motor, the lead screw body is rotated, which causes the lead screw sleeve and the clamping seat to move towards the bottle and make contact and squeeze, thereby clamping and fixing the bottle. At this time, the anti-slip pad helps to increase the friction between the clamping seat and the bottle, thus preventing the bottle from rotating. This also helps to prevent the bottle from rotating with the cap during the capping process, improving the capping effect and quality.

[0009] Preferably, the fixing frame includes a top plate and a bottom plate. The bottom side of the bottom plate has four annularly spaced through slots. Threaded rods are movably installed on the inner side of the through slots via bearings. A first bevel gear is fixedly installed at the outermost end of each threaded rod. The threaded rod and the first bevel gear form a group, and a total of four groups are provided.

Thus, under the action of the thread, the inner thread sleeve and the main gear rotate, which facilitates the power for the movement of the clamping plates and ensures the uniformity of the movement of the four sets of clamping plates. Moreover, under the action of the spring, it is convenient to push the top rod to reset.

[0018] 1. This utility model places the bottle inside the groove on the top side of the base, and then the drive motor drives the lead screw body to rotate, which causes the lead screw sleeve and the clamping seat to move towards the bottle and make contact and squeeze, thereby clamping and fixing the bottle. At this time, the anti-slip pad helps to increase the friction between the clamping seat and the bottle, thereby preventing the bottle from rotating. This helps to prevent the bottle from rotating with the cap during the capping process, thus improving the capping effect and quality.

[0019] 2. This utility model places the bottle cap on the top of the bottle. By starting the cylinder, the motor frame and the fixing frame move downward, so that the bottle cap contacts the top rod and pushes the top rod upward.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figures 1-5 As shown, the present invention provides an automatic bottle cap screwing mechanism, including a base 1, two baffles 2 on the bottom side of the base 1, a lead screw body between the baffles 2, an adjusting seat 3 movably installed on the top side of the base 1, a clamping seat 4 fixedly installed on the opposite side of the adjusting seat 3, a support frame 5 fixedly installed at the rear end of the top side of the base 1, a cylinder 6 on the top side of the support frame 5, a motor frame 7 fixedly installed at the drive end of the cylinder 6, a rotary motor 8 on the inner side of the motor frame 7, a fixed frame 9 fixedly installed at the drive end of the rotary motor 8, a drive seat 10 movably installed on the inner side of the fixed frame 9 via a bearing, a push rod 11 threadedly connected to the inner side of the drive seat 10, a clamping plate 12 on the bottom side of the fixed frame 9, and a transmission assembly 13 on the outer end of the top side of the fixed frame 9.

[0029] Specifically, the adjusting seat 3 includes a lead screw sleeve 301, a connecting seat 302, and a support column 303. The lead screw body is threadedly connected to the inner side of the lead screw sleeve 301, and the connecting seat 302 is fixedly installed on the outer side of the lead screw sleeve 301. The support column 303 is fixedly installed between the connecting seat 302 and the clamping seat 4. An anti-slip pad is provided on the inner side of the clamping seat 4. The advantage is that by placing the bottle inside the groove on the top side of the base 1, and then driving the lead screw body to rotate under the action of the drive motor, the lead screw sleeve 301 and the clamping seat 4 move towards the bottle and make contact and squeeze, thereby clamping and fixing the bottle. At this time, the anti-slip pad helps to increase the friction between the clamping seat 4 and the bottle, thereby preventing the bottle from rotating. This helps to prevent the bottle from rotating with the cap during the capping process, improving the capping effect and quality.

[0030] Specifically, the fixing frame 9 includes a top plate 901 and a bottom plate 902. The bottom side of the bottom plate 902 has four annularly spaced through slots 9021. Threaded rods 9022 are movably mounted on the inner side of each through slot 9021 via bearings. A first bevel gear 9023 is fixedly mounted at the outermost end of each threaded rod 9022. The threaded rods 9022 and the first bevel gear 9023 form a group, with a total of four groups. The advantage is that the first bevel gear 9023 drives the threaded rods 9022 to rotate, thus providing power for the movement of the clamping plate 12 and facilitating the clamping of the bottle cap.

[0031] Specifically, a threaded sleeve 1201 is fixedly installed on the top side of the clamping plate 12. The threaded sleeve 1201 is threadedly connected to the outside of the threaded rod 9022. The clamping plate 12 has an arc-shaped structure, and the inner side of the clamping plate 12 is provided with anti-slip ridges 1202. A total of four sets of these threads are provided on the clamping plate 12. The advantage is that by rotating the threaded rod 9022, the four sets of threaded sleeves 1201 and the clamping plate 12 can easily move towards the bottle cap and clamp and fix it, which helps to improve the stability and balance of clamping, and improve the capping effect and quality.

[0032] Example 2:

[0033] like Figures 1-5As shown, this is an improvement on the previous embodiment. Specifically, the drive seat 10 includes an inner threaded sleeve 1001 and a main gear 1002. The inner threaded sleeve 1001 is movably mounted on the inner side of the middle of the base plate 902 via a bearing, and the main gear 1002 is fixedly mounted on the top of the inner threaded sleeve 1001. A push rod 11 is threadedly connected to the inner side of the inner threaded sleeve 1001, and a telescopic rod 1101 is fixedly mounted between the push rod 11 and the top plate 901. A spring is provided on the outer side of the telescopic rod 1101. The advantage is that by starting the cylinder 6, the motor frame 7 and the fixed frame 9 are moved downward, so that the bottle cap contacts the push rod 11 and pushes the push rod 11 upward in the opposite direction. Thus, under the action of the thread, the inner threaded sleeve 1001 and the main gear 1002 are rotated, which facilitates the provision of power for the movement of the clamping plates 12 and ensures the uniformity of the movement of the four sets of clamping plates 12.

[0034] Specifically, the transmission assembly 13 includes a transmission gear 1301, a second bevel gear 1302, an idler gear 1303, and a stabilizing shaft 1304. The second bevel gear 1302 is fixedly installed on the bottom side of the transmission gear 1301. The second bevel gear 1302 is meshed with the first bevel gear 9023. The transmission gear 1301, the main gear 1002, and the idler gear 1303 are meshed together. The stabilizing shaft 1304 is fixedly installed on the top side of the idler gear 1303. The top end of the stabilizing shaft 1304 is movably installed on the bottom side of the top plate 901 via a bearing. The transmission assembly 13 has a total of four sets. The advantage is that the rotation of the inner threaded sleeve 1001 and the main gear 1002 drives the idler gear 1303, the transmission gear 1301 and the second bevel gear 1302 to rotate. Then, the second bevel gear 1302 drives the first bevel gear 9023 and the threaded rod 9022 to rotate, thereby making the four sets of clamping plates 12 close to the bottle cap for clamping and fixing, which facilitates power transmission.

[0035] In use, the bottle is placed inside the groove on the top side of the base 1. Then, the drive motor rotates the lead screw body, causing the lead screw sleeve 301 and the clamping seat 4 to move towards the bottle and contact and squeeze, thus clamping and fixing the bottle. At this time, the anti-slip pad helps to increase the friction between the clamping seat 4 and the bottle, thereby preventing the bottle from rotating. This helps to prevent the bottle from rotating with the cap during the capping process, improving the capping effect and quality. Next, the cap is placed on the top of the bottle, and then the starting cylinder 6 drives the motor frame 7 and the fixing frame 9 to move down, so that the cap contacts the push rod 11 and pushes the push rod 11 in the opposite direction. The upward movement causes the inner threaded sleeve 1001 and the main gear 1002 to rotate under the action of the thread. This, in turn, causes the idler gear 1303, the transmission gear 1301, and the second bevel gear 1302 to rotate. Subsequently, the second bevel gear 1302 drives the first bevel gear 9023 and the threaded rod 9022 to rotate, thereby causing the four sets of clamping plates 12 to approach the bottle cap for clamping and fixing. Then, driven by the rotary motor 8, the fixing frame 9, the clamping plates 12, and the bottle cap rotate to complete the cap tightening action. The bottle cap is clamped with high stability, and the anti-slip ridges 1202 help to prevent the bottle cap from slipping sideways, improving the tightening effect and cap tightening stability.
