Description

Technical Field

[0001] The utility model relates to the technical field of automatic installation and tightening of bottle caps, in particular to an automatic cap screening and cap screwing device. Background Art

[0002] In the process of filling and packaging powders, granules and liquids, it is necessary to install and tighten the bottle caps on the bottles. However, in the existing production line, the selection and installation of bottle caps are generally carried out in two steps. That is, the bottle caps need to be selected first, and then transferred to the mechanical equipment specially used for screwing and installing the caps, and then the equipment will carry out the installation of the bottle caps.

[0003] It can be seen that the existing production line is still unable to realize the operation process of directly installing and fixing the screened bottle caps on the bottles, resulting in that the work efficiency of installing the bottle caps on the bottles is still relatively low. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide an automatic cap screening and cap screwing device, which, when in use, can screen out the bottle caps and directly install them on the bottles, thereby more efficiently completing the automated process of installing the bottle caps on the bottles.

[0007] A bottle cap sieve seat is fixedly mounted on the frame, a bottle cap storage is fixedly mounted on the top of the bottle cap sieve seat, a bottle cap sieve block is movably arranged on the inner side, a bottle cap sieve plate is movably arranged on the bottom, the bottle cap sieve plate is driven by a push-pull mechanism 1 to move left and right, and the bottle cap sieve block is driven by a push-pull mechanism 2 to move left and right, a lifting screw rod and a guide rail module are also fixedly mounted on the frame, a lifting module servo motor is mounted on the top of the lifting screw rod and the guide rail module, a torsion servo motor is fixedly mounted on the front side, a torsion transfer cylinder is mounted on the output shaft end of the torsion servo motor, a bottle cap clamp is mounted on the piston shaft end of the torsion transfer cylinder, and a bottle conveying line and a bottle clamping device that work in conjunction are arranged directly below the bottle cap clamp.

[0008] As an improvement, the push-pull mechanism 1 is a bottle cap sieve plate cylinder, the cylinder body of the bottle cap sieve plate cylinder is mounted and fixed on the frame, and the piston shaft end is fixedly connected to the bottle cap sieve plate.

[0009] As an improvement, the second push-pull mechanism is a bottle cap screen block cylinder, the cylinder body of the bottle cap screen block cylinder is mounted and fixed on the frame, and the piston shaft end is fixedly connected to the bottle cap screen block.

[0010] The advantages of the utility model over the prior art are: when the utility model is used, the bottle cap screen seat, the bottle cap screen block and the bottle cap screen plate can be used to quickly and accurately screen out the bottle caps required for the bottle, and then the bottle caps can be smoothly conveyed to the bottle cap gripper, and then the lifting module servo motor and the torsion servo motor can cooperate to complete the steps of tightening the bottle caps and installing them on the bottles. Overall, the utility model can complete the two steps of screen caps and screw caps at one time and efficiently. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the term "including" and any variation thereof are intended to cover non-exclusive inclusions.

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] An automatic cap screening and capping device, comprising a frame 1, a bottle cap storage 2, a bottle cap screen seat 3, a bottle cap screen block 4, a bottle cap screen plate 5, a lifting module servo motor 6, a lifting screw and guide rail module 7, a torsion servo motor 8, a torsion transmission cylinder 9, a bottle cap clamping claw 10, a bottle clamping device 11, a bottle conveying line 12, a bottle cap screen plate cylinder 13 and a bottle cap screen block cylinder 14;

[0017] A bottle cap sieve seat 3 is fixedly mounted on the frame 1, a bottle cap storage 2 is fixedly mounted on the top of the bottle cap sieve seat 3, a bottle cap sieve block 4 is movably arranged on the inside, and a bottle cap sieve plate 5 is movably arranged on the bottom, the cylinder body of the bottle cap sieve plate cylinder 13 is fixedly mounted on the frame 1, and the piston shaft end is fixedly connected to the bottle cap sieve plate 5, the cylinder body of the bottle cap sieve block cylinder 14 is fixedly mounted on the frame 1, and the piston shaft end is fixedly connected to the bottle cap sieve block 4, a lifting screw rod and guide rail module 7 is also fixedly mounted on the frame 1, a lifting module servo motor 6 is installed on the top of the lifting screw rod and guide rail module 7, a torsion servo motor 8 is fixedly mounted on the front side, a torsion transfer cylinder 9 is installed on the output shaft end of the torsion servo motor 8, a bottle cap clamp 10 is installed on the piston shaft end of the torsion transfer cylinder 9, and a bottle conveying line 12 and a bottle clamping device 11 that work in conjunction with the bottle cap clamp 10 are arranged directly below the bottle cap clamp 10.

[0018] As a preferred embodiment, two bottle cap storages 2 are evenly arranged along the left and right directions, and the bottle cap sieve block 4 is used for the second row of bottle cap storages 2 for supplying caps. Three or even more bottle cap storages 2 may be arranged, and for each additional row of bottle cap storages 2, one more bottle cap sieve block 4 structure is correspondingly arranged for supplying caps.

[0019] In the specific implementation of this embodiment:

[0020] The bottle caps need to be pre-stacked in the bottle cap storage 2 (the bottle cap storage 2 can be configured to be easy to load and unload). When the bottle 15 passes by, the bottle clamping device 11 first operates to position the bottle 15 to the middle position and align it with the bottle cap clamping claw 10, ready to tighten.

[0021] The bottle caps can be screened out one by one from the storage in the bottle cap screen seat 3 and fall into the groove of the bottle cap screen plate 5. At this time, the bottle cap screen plate cylinder 13 is actuated to align the axis of the bottle cap on the bottle cap screen plate 5 with the bottle cap clamping claw 10, so that the capping is completed;

[0022] The bottle cap clamp 10 is connected to the lifting screw and the guide rail module 7 to realize lifting and lowering motion. After the cap is supplied, the lifting module servo motor 6 is activated to lower the bottle cap clamp 10 to slightly above the bottle cap and clamp the bottle cap. Then the lifting module servo motor 6 is activated again to return the bottle cap clamp 10 to its original position and allow the bottle cap to leave the sieve plate slot.

[0023] At this time, the bottle cap screen plate 5 is reset, and the bottle cap remains directly above the bottle 15. The bottle cap clamp 10 is connected to a torsion transmission cylinder 9, and its end is connected to a torsion servo motor 8 and its coupling. At this time, the forward rotation of the torsion servo motor 8 can drive the bottle cap at the end to rotate forward. At the same time, the lifting module servo motor 6 also moves, and the bottle cap can be gradually tightened to the bottom bottle 15. When the bottle cap is tightened, because the bottle is clamped, the torque will suddenly increase. After the torsion servo motor 8 detects the change in torque, it will no longer continue to run, and the bottle 15 capping is completed, and all actions are reset after a slight delay.

[0024] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
