Description

Technical Field

[0001] The utility model relates to the technical field of capping machines, in particular to a high-speed capping machine structure. Background Art

[0002] The capping machine is an important equipment for packaging after drug filling. There are mainly three-pass capping, large single knife, small single knife and other capping methods. At present, the commonly used method is the small single knife rotation and revolution method. Its main structure consists of a capping knife, a transmission structure and a screw auger. The medicine bottle is positioned by the upper capping head and the lower floating base, and the capping is completed by the revolution of the capping knife + the rotation of the medicine bottle.

[0003] The method of small single blade self-rotation and revolution has high capping efficiency and has become one of the main technical routes. However, the currently popular method of small single blade self-rotation and revolution still has the following disadvantages: First, when capping, the medicine bottle is positioned in the dial after being transferred by the auger, and then transferred to the next dial after capping on the dial. The movement route of the medicine bottle is "S" shaped. For example, the transmission structure of the Chinese invention patent applications with application publication numbers CN115159414 and CN11574479 are all of the above type. The medicine bottle is easily in a state of force balance when entering and exiting the dial, and the bottle may be stuck or even crushed here; second, the rolling knife is fixed on the knife holder. Since the rolling knife will gradually wear out during the capping process, the replacement process requires adjusting at least 3-6 screws and recalibrating the position of the rolling knife, which is relatively troublesome. Summary of the invention

[0004] The utility model aims to overcome the deficiencies in the above-mentioned background technology and provide a high-speed capping machine structure, which has high capping efficiency, convenient capping blade replacement and is not prone to bottle jamming.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A high-speed capping machine structure comprises a frame, a Lello triangular roller, and two bottle conveying channels; the Lello triangular roller rotates under power drive, and the motion trajectory of its outer edge is square; the two bottle conveying channels are respectively arranged at two opposite sides of the square, parallel to each other and conveying in opposite directions, and each bottle conveying channel is indented into the square by a distance, so that the neck parts of the medicine bottles conveyed in a single row on the bottle conveying channel can overlap with the motion trajectory of the Lello triangular roller, thereby achieving capping.

[0007] Preferably, the bottle conveying channel comprises a bottle supporting channel on the lower side and a capping channel on the upper side; the bottle supporting channel and the capping channel are both provided with conveyor belts, the conveyor belt of the bottle supporting channel is evenly provided with floating heads for supporting medicine bottles, and the conveyor belt of the capping channel is evenly provided with capping heads for pressing the aluminum caps to be rolled, and the capping heads correspond one to one with the floating heads.

[0008] Preferably, the bottle supporting channel has guardrails on both sides, and the spacing between the guardrails on both sides is greater than the diameter of the medicine bottle.

[0009] Preferably, the Lello triangular rolling cutter is mounted on an eccentric shaft, which is arranged on a frame and driven by the power.

[0010] The beneficial effects of the utility model are as follows: the utility model utilizes the movement characteristics of the Lello triangle, sets two linear bottle conveying channels on the two sides of the movement trajectory of the Lello triangle rolling cutter, and then cooperates with the existing floating head and capping head structure to press the medicine bottle, and the bottle cap is rolled during the rotation of the Lello triangle rolling cutter. The linear bottle conveying channel can reduce the bottle jamming phenomenon. The Lello triangle rolling cutter is installed on the eccentric shaft. During installation, it only needs to be locked in place axially. No radial calibration is required after replacement, and it is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] In order to enable ordinary technicians in the field to more clearly understand the purpose, technical solutions and advantages of the utility model, the utility model is further explained below in conjunction with the accompanying drawings and embodiments, but the utility model is not limited to the following embodiments.

[0016] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0017] like Figure 1As shown, this embodiment provides a high-speed capping machine structure, including a frame 10, a Lello triangular guillotine cutter 1 mounted thereon, and two bottle conveying channels 2. The Lello triangular guillotine cutter 1 is mounted on an eccentric shaft, which is arranged on the frame 10 and connected to a power source 8 (such as a motor), as shown in FIG. Figure 2 As shown, according to the constant-width curve characteristics of the Lello triangle (i.e., the Lero triangle, the Lulox triangle), when the Lello triangle mill 1 rotates under power drive, the motion trajectory 1.1 of its outer edge is basically square. This embodiment utilizes this characteristic to arrange two bottle conveying channels 2 at two opposite sides of the square, which are parallel to each other and have opposite conveying directions. Each bottle conveying channel 2 is retracted toward the inside of the square by a certain distance, so that the neck parts of the medicine bottles 4 conveyed in a single row on the bottle conveying channel 2 can partially overlap with the motion trajectory 1.1 of the Lello triangle mill 1, so that the Lello triangle mill 1 can roll the aluminum caps 4.1 on the medicine bottles 4 during rotation.

[0018] Each bottle conveying channel 2 includes a bottle supporting channel 2.1 at the lower side and a capping channel 2.2 at the upper side. The bottle supporting channel and the capping channel are both provided with a conveyor belt 7 driven by respective motors 6. The conveyor belt of the bottle supporting channel is evenly provided with floating heads 3 for supporting medicine bottles 4. The conveyor belt of the capping channel is evenly provided with capping heads 5 for pressing aluminum caps 4.1 to be rolled. The floating heads and the capping heads are both installed in respective accommodation blocks 9, and the capping heads correspond to the floating heads one by one.

[0019] In the bottle conveying channel 2, guardrails can be provided on both sides of the bottle supporting channel 2.1 according to the situation, and the spacing between the guardrails on both sides is greater than the diameter of the medicine bottle 4. A bottle conveying mechanism is provided at the front end of the bottle supporting channel 2.1, and a bottle discharging mechanism is provided at the rear end. For example, the bottle conveying mechanism and the bottle discharging mechanism can select existing mechanisms such as conveyor belts, bottle conveying screws, and bottle shifting wheels according to the on-site situation.

[0020] In this embodiment, the capping head 5 and the floating head 3 are both existing components, and their structures, installation methods and working principles are all existing technologies. Figure 3 As shown, during capping, the floating head 3 supports the bottom of the medicine bottle 4, and the capping head 5 descends to press the aluminum cap 4.1 at the bottle mouth. During the rotation process, the roller squeezes the aluminum cap 4.1 from the bottle neck to wrap the edge and complete the capping.

[0021] Similarly, the "Lello triangle" in this embodiment can be other "Lello polygons" that can realize the square motion trajectory 1.1. According to the number of sides, the bottle entry and exit positions and the positions of the floating head 3 and the capping head 5 can be adjusted. According to the size of the bottle, rollers with different numbers of sides can be designed, or the position of the bottle conveying channel 2 can be adjusted to achieve a better capping effect.

[0022] When rolling the cap, the process is as follows:

[0023] The two bottle conveying channels 2 are driven by the bottle feeding mechanism at the front end to push the medicine bottle 4 onto the floating head 3 of the bottle supporting channel 2.1, and the capping head 5 of the capping channel 2.2 presses the aluminum cap 4.1 and the rubber plug onto the mouth of the medicine bottle 4;

[0024] As the Lello triangular rolling blade 1 rotates and the medicine bottle 4 moves forward, it contacts the pressed medicine bottle 4, and the medicine bottle 4 also rotates. As the Lello triangular rolling blade 1 rotates, the lower edge of the aluminum cap 4.1 is gradually rolled by the Lello triangular rolling blade 1 until the rolling is completed after at least one rotation, thereby achieving sealing.

[0025] After the capping is completed, the bottle supporting channel 2.1 delivers the medicine bottle, the capping head 5 and the floating head release the medicine bottle 4, and the bottle is delivered by the bottle discharging mechanism at the rear end. The same applies to the bottle conveying channel on the other side.

[0026] The above is only a preferred embodiment of the utility model. For those skilled in the art, the utility model can be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
