DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The specific embodiments of the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0022] As Figures 1 to 4 shown, a capping machine of a preferred embodiment of the present utility model includes a machine base 1, a positioning mechanism 2 provided on the machine base 1 for clamping a bottle body, a capping mechanism 3 for screwing a pump cap 6 onto the bottle body, and a cap clamping mechanism 4 for driving the capping mechanism 3 to clamp or loosen the pump cap 6; at least two groups of the capping mechanisms 3 are provided, and the capping mechanism 3 includes a capping block 31 and a capping driving assembly for driving the capping block 31 to rotate, and the rotation direction of the capping block 31 is opposite to the screwing direction of the pump cap 6; the cap clamping mechanism 4 includes a movable seat 41 and a cap clamping driving assembly 42, and the cap clamping driving assembly 42 is preferably a cylinder. The capping driving assembly is provided on the movable seat 41, and the output end of the cap clamping driving assembly 42 is connected to the movable seat 41 and drives the movable seat 41 to approach or move away from the pump cap 6.

[0023] The present utility model clamps and fixes the bottle body through the positioning mechanism 2, and then the cap clamping mechanism 4 drives the capping mechanism 3 to make all the capping blocks 31 clamp the pump cap 6. By synchronously rotating the capping blocks 31, the pump cap 6 is quickly screwed onto the bottle body; after the positioning mechanism 2 releases the bottle body and the cap clamping mechanism 4 drives the capping mechanism 3 to move away from the pump cap 6, the bottle body is quickly taken out and a bottle body to be capped is re-placed.

[0024] In this embodiment, there are two sets of the capping mechanisms 3. The capping drive assembly includes a capping driver 32, a drive gear, a transmission gear 33, a transmission shaft 34, and a mating sleeve 35. The capping driver 32 is arranged on the movable seat 41. The capping driver 32 is preferably a motor. The output end of the capping driver 32 is connected to the drive gear and drives the drive gear to rotate on the movable seat 41. The transmission gear 33 is rotatably connected to the movable seat 41. There are two transmission gears 33 which are respectively meshed with the drive gear. The transmission shaft 34 is connected to the bottom of the transmission gear 33. The capping block 31 is arranged at the bottom of the transmission shaft 34. The mating sleeve 35 is arranged at the bottom of the movable seat 41, and the mating sleeve 35 is sleeved on the outer periphery of the transmission shaft 34 and is spaced apart from the transmission shaft 34. In this way, the two sets of bottle clamping mechanisms 4 respectively drive the two sets of capping mechanisms 3 to move closer to the middle to clamp the pump cover 6, and the four capping blocks 31 synchronously tighten the pump cover 6 to improve the tightening quality and working efficiency.

[0025] Specifically, the movable seat 41 is arranged in the middle of the machine base 1. A limiting hole which is movably matched with the mating sleeve 35 is opened in the middle of the machine base 1. When the bottle clamping drive assembly 42 on the bottle clamping mechanism 4 drives the capping mechanism 3 on the movable seat 41 to move closer to or away from the pump cover 6, the mating sleeve 35 is in limiting cooperation with the limiting hole, playing a guiding role and improving the moving stability.

[0026] Exemplarily, a positioning post 36 which abuts against the pump head 61 on the pump cover 6 is arranged on the mating sleeve 35 located on the front side of the machine base 1 and facing the tightening direction of the pump cover 6. Since the pump head 61 will be driven when the pump cover 6 rotates, and at the same time the pump head 61 on the pump cover 6 can rotate with the pump cover 6, the positioning post 36 is in abutting cooperation with the pump head 61, thus avoiding the pump cover 6 from moving during the tightening process and realizing the positioning of the pump head 61.

[0027] Preferably, the positioning post 36 is fixed on the mating sleeve 35 through a mounting seat 37, and the positioning post 36 can be quickly disassembled and assembled according to needs.

[0028] Exemplarily, there are two sets of the positioning mechanisms 2 which are symmetrically arranged at the bottom of the machine base 1. The positioning mechanism 2 includes a clamping block 21 and a clamping driver. Among them, Figure 2 only a single clamping block 21 is shown in the figure. The clamping driver is preferably a cylinder. The output end of the clamping driver is connected to the clamping block 21 and drives the clamping block 21 to move closer to or away from the bottle body. The two sets of positioning mechanisms 2 fix the bottle body to realize the centering and fixing of the bottle body.

[0029] Further, a V-shaped notch 211 is arranged on the side of the clamping block 21 facing the bottle body. The cooperation with the V-shaped notch 211 can accurately fix the bottle body at the exact center of the two clamping blocks 21, ensuring the accurate fixing position of the bottle body.

[0030] Exemplarily, a gland mechanism is provided on the machine base 1. The gland mechanism includes a gland driver and a gland plate 52. The output end of the gland driver is connected to the gland plate 52 and can drive the gland plate 52 to move up and down to press the pump cover 6 tightly on the bottle body, improving the tightening effect of the pump cover 6.

[0031] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0032] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
