A telescopic ring is located at the lower part of the main cylinder, and the telescopic ring is telescopically connected to the lower end of the main cylinder. A feed pipe is located on the side wall of the main cylinder. The interior of the main cylinder has several L-shaped supports arranged in a circular array. The inner wall of the main cylinder has several elongated holes, with each L-shaped support corresponding to one of the elongated holes. The middle section of each L-shaped support is hinged to one of the elongated holes, and a return spring is connected to the end of each L-shaped support. The other end of the return spring is connected to the cylinder wall of the main cylinder. A telescopic cylinder is connected to the upper end of the main cylinder, and the telescopic cylinder and the main cylinder are telescopically nested. A second return spring is located between the telescopic cylinder and the main cylinder. A tightening rod passes through the telescopic cylinder and is inserted into the interior of the main cylinder.

[0008] Preferably, the top of the telescopic ring is provided with several connecting rods, which are inserted into the inner wall of the main body cylinder. A return spring is sleeved on the outside of the connecting rods, and the two ends of the return spring abut against the main body cylinder and the telescopic ring, respectively.

[0009] Preferably, the number of L-shaped legs is four, and the inner wall of the main body cylinder is provided with four elongated holes.

[0010] Preferably, the feed pipe is positioned above the plurality of L-shaped supports.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) The bottle cap tightening head provided by this utility model has a feed pipe on the side wall of the main body. The bottle cap is introduced from the feed pipe. Since the L-shaped support legs are evenly arranged in a ring array, the bottle cap falls into the center position of the L-shaped support legs. At this time, the initial positioning of the bottle cap is completed.

[0013] (2) The bottle cap tightening head provided by this utility model presses down the main body cylinder, the telescopic ring covers the glass bottle, the telescopic cylinder continues to press down, the lower edge of the telescopic cylinder can abut against the L-shaped support foot, the L-shaped support foot retracts, the bottle cap falls down and fits the bottle mouth of the glass bottle; further tightening rod moves down to press the bottle cap, and then the tightening rod rotates to screw the bottle cap into the bottle mouth of the glass bottle.

[0019] 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.

[0020] A screw-on head for a capping machine includes a main body cylinder 1. An inlet pipe 2 is provided on the side wall of the main body cylinder 1, through which bottle caps are introduced into the main body cylinder 1. Inside the main body cylinder 1, four L-shaped supports 3 are provided, arranged in a circular array. Four elongated holes 4 are provided on the inner side of the main body cylinder 1, with the four L-shaped supports 3 corresponding to and inserted into the four elongated holes 4. The middle section of each L-shaped support 3 is hinged to one of the elongated holes 4. A return spring 5 is connected to the end of each L-shaped support 3, with the other end of the return spring 5 connected to the cylinder wall of the main body cylinder 1. Under the action of the return spring 5, the L-shaped supports 3 spring up, and the four L-shaped supports 3 can precisely catch the bottle caps falling from the inlet pipe 2.

[0021] A telescopic cylinder 6 is connected to the upper end of the main body cylinder 1. The telescopic cylinder 6 and the main body cylinder 1 are connected in a telescopic nesting manner, and a return spring 7 is provided between them. Under the action of the return spring 7, the telescopic cylinder 6 and the main body cylinder 1 spring up. A tightening rod 8 passes through the telescopic cylinder 6 and enters the interior of the main body cylinder 1.

[0022] A telescopic ring 9 is provided at the bottom of the main body cylinder 1, and the telescopic ring 9 is telescopically connected to the lower end of the main body cylinder 1. Several connecting rods 10 are provided at the top of the telescopic ring 9, and the connecting rods 10 pass through the inner wall of the main body cylinder 1. A return spring 31 is sleeved on the outside of the connecting rods 10, and the two ends of the return spring 31 abut against the main body cylinder 1 and the telescopic ring 9 respectively.

[0023] During use, a feed pipe 2 is provided on the side wall of the main body cylinder 1. The bottle cap is introduced through the feed pipe 2. Since the L-shaped support legs 3 are evenly arranged in a circular array, the bottle cap falls into the center of the L-shaped support legs 3, thus completing the initial positioning of the bottle cap. The main body cylinder 1 is pressed down, the telescopic ring 9 covers the glass bottle, and the telescopic cylinder 6 continues to press down, so that the lower edge of the telescopic cylinder 6 abuts against the L-shaped support legs 3. The L-shaped support legs 3 retract, and the bottle cap falls down to cover the mouth of the glass bottle. The tightening rod 8 is then moved down to hold the bottle cap in place. Then the tightening rod 8 is rotated to screw the bottle cap into the mouth of the glass bottle.

[0024] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
