Description

Technical Field

[0001] The utility model relates to the field of filling and capping, in particular to a filling and capping machine. Background Art

[0002] Liquid filling machines are generally used in the beverage manufacturing industry. When manufacturing beverages, liquid filling machines fill beverages into plastic bottles and then cap the plastic bottles. In the Chinese utility model patent with announcement number CN208038009U, a filling and capping machine is disclosed, including a conveying device, a first supporting device and a second supporting device. The first supporting device includes a first base and a first bracket, and the second supporting device includes a second base and a second bracket. The conveying device is fixedly mounted on the first base and the second base. The first bracket is provided with a filling device, and the second bracket is provided with a capping device, which realizes the automatic filling and capping of plastic bottles, improves production efficiency, and reduces labor. In the above structure, the bottle cap is placed in the feeding tray and falls down through the feeding track to cover the top of the plastic bottle. There is no corresponding capping structure above it, that is, the bottle cap may be offset and tilted after being placed on the plastic bottle, which may cause the subsequent accurate tightening. For this reason, we designed a filling and capping machine. Utility Model Content

[0003] In order to solve the technical problem that a cap may deviate and tilt after being placed on a plastic bottle, the utility model provides a filling and capping machine.

[0004] The utility model is implemented by the following technical scheme: a filling and capping machine, comprising a machine platform 1 and a machine platform 2, wherein conveyor belts are transversely installed above the machine platforms 1 and 2, and a filling mechanism is installed on the machine platform 1 through a bracket 1, a deflection mechanism is arranged above the machine platform 2, and the deflection mechanism is located at the front side of the conveyor belt, a bottle cap unloading mechanism is installed above the machine platform 2 through a bracket 2, and a feeding track is installed on the bracket 2, the upper end of the feeding track is connected to the bottle cap unloading mechanism, and a capping mechanism is installed at the lower end of the feeding track, and the capping mechanism is located above the front side of the deflection mechanism;

[0006] As a further improvement of the above scheme, a lifting cylinder is suspended above the second bracket, an L-shaped frame is installed below the push rod of the lifting cylinder, a rotating cylinder is installed on the L-shaped frame, a clamping joint is installed on the push rod of the rotating cylinder, and the lifting cylinder is located on the left side of the capping mechanism. After the bottle is filled, it will move to the deflection mechanism and rotate. During this process, the bottle will be covered with a bottle cap and rotated again to be placed under the clamping joint. After the clamping joint is clamped above the bottle cap under the action of the lifting cylinder, the cylinder is rotated to rotate it, so that the bottle cap is tightened.

The positioning plate is first pushed out under the action of the positioning cylinder to prevent the bottle from moving, and then the limiting plate is pushed out to fix the bottle, and the separating plate is pushed out to separate the bottles on the left and right sides, and filling can be carried out at this time. Then the limiting plate and the positioning plate are retracted to move the filled bottles, and then the positioning plate is pushed out, the separating plate is retracted, the limiting plate is pushed out again for limiting, and the separating plate is pushed out to separate the bottles on the left and right sides, and the above operations are repeated. In this way, it can be ensured that when the filled bottles move to the left, the empty bottles will not be packaged due to the excessively fast moving speed, thereby improving the accuracy.

[0009] As a further improvement of the above scheme, the bottle cap unloading mechanism includes a storage frame obliquely arranged above the second bracket, a rotating disk is rotatably installed inside the storage frame, and a plurality of placement grooves distributed in a ring are opened on the rotating disk, and an outer ring of the storage frame is also provided with a discharge port, the width of the discharge port is greater than the thickness of one bottle cap and less than the thickness of two bottle caps, and the upper end of the feeding track is connected to the discharge port, and a plurality of bottle caps with the bottle mouths facing downwards are stacked and placed in the plurality of placement grooves, and when the rotating disk rotates, the bottle caps can enter the feeding track through the discharge port, and then can be placed above the bottle, and the occurrence of the bottle mouth of the bottle cap facing upward is avoided.

[0011] As a further improvement of the above scheme, both front and rear ends of the mounting frame are rotatably mounted with limit blocks through shaft pins, the front end of the limit block is provided with a limit head with an arc structure, and the inward sides of the two limit heads form a semicircular structure matching the bottle cap, and the bottle cap can be placed between the inclined plate and the limit head, so that the bottle cap can be limited and prevented from falling;

[0012] Positioning posts are installed at the front and rear of the mounting frame, and a clamping spring is sleeved on the positioning posts. A movable hole in a strip structure is opened on the limit block, and the positioning post passes through the movable hole and is placed outside the limit block, and the clamping spring abuts against the outer surface of the limit block.
