Detailed Implementation

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, as Figs. 1-3 As shown, this embodiment aims to provide a device that can automatically cut the bottle mouth of blow-molded plastic buckets (hand-held oil drums) to reduce the labor intensity of workers. To this end, the automatic cutting device for blow-molded plastic buckets provided in this embodiment includes a conveyor belt 1 for conveying the plastic bucket to be cut, a pushing and clamping mechanism 3 arranged on both sides of the conveyor belt 1, and an automatic cutting mechanism 4 arranged above the pushing and clamping mechanism 3. In this embodiment, the conveyor belt 1 is a common existing conveyor belt 1, and adjustable baffles 11 are arranged on both sides of it to restrain the shape of the plastic bucket 2 during the movement.

[0020] The main purpose of the push-and-grip mechanism 3 is to push the plastic bucket 2 to the middle of the conveyor belt 1 and form a clamp on the plastic bucket 2 to ensure the stability of the plastic bucket 2. To this end, the push-and-grip mechanism 3 includes push cylinders 31 set on both sides of the conveyor belt 1 and push plates 32 set on the power end of the push cylinders 31. Considering that the bottle mouth needs to be cut, the clamping part of the push plate 32 should be located in the upper middle part of the plastic bucket 2.

[0021] In order to simulate the action of the worker's cut, the automatic cutting mechanism 4 provided by the embodiment includes a frame 41 arranged above the push-clamping mechanism 3 and a push-in cylinder 42 arranged on one side of the frame 41, the power end of the push-in cylinder 42 is arranged towards the center direction of the conveying belt 1, and the main function of the push-in cylinder 42 is to push the cutting knife 51 into the plastic bucket 2 so as to be inserted into the plastic bucket 2. For this purpose, the power end of the push-in cylinder 42 is connected with a motor base 43, the motor base 43 is provided with a cutting motor 46, the power end of the cutting motor 46 is arranged towards the conveying belt 1, that is, the cutting motor 46 is arranged downward, meanwhile, a connecting plate 47 is sleeved on the power end of the cutting motor 46, the connecting plate 47 is arranged horizontally, a connecting column 48 is arranged on the end of the connecting plate 47 away from the cutting motor 46, the end of the connecting column 48 away from the connecting plate 47 is connected with the cutting knife 51, the cutting edge of the cutting knife 51 is arranged towards the center direction of the conveying belt 1, and the cutting knife 51 is arranged below the connecting plate 47. In this way, a tilted U-shaped arrangement is formed between the connecting plate 47 and the cutting knife 51.

[0022] In order to ensure the stability of the movement of the motor base, a sliding block 44 is arranged on the bottom of the motor base 43, and a guide rail 45 matched with the sliding block is arranged on the frame, so that the stability of the movement of the motor base 43 is ensured through the arrangement of the sliding block 44 and the guide rail 45, and the stability of the insertion of the cutting knife 51 is ensured.

[0023] Through the above arrangement, when the plastic bucket 2 moves to the specified position, the push-clamping mechanism 3 acts to fix the plastic bucket 2, at this time, the push-in cylinder 42 acts to drive the movement of the cutting motor 46 and the cutting knife 51, so that the cutting knife 51 can be inserted into the position of the bottle mouth, then the cutting motor 46 acts to realize the cutting of the plastic bucket 2.

[0024] In order to avoid the influence of the automatic cutting mechanism 4 on the conveying of the plastic bucket 2, in the embodiment, the frame 41 is arranged above the push-clamping mechanism 3 in a lifting manner. Specifically, a lifting cylinder 6 is arranged on the side wall of the conveying belt 1, the power end of the lifting cylinder 6 is connected with the frame 41, so that when the cutting is completed, the push-in cylinder 42 is reset, the lifting cylinder 6 works, the push cylinder 31 is reset, and the conveying belt 1 works.

[0025] In order to facilitate the replacement of the cutting knife 51, a cutting knife seat 5 is connected to the end of the connecting column 48 away from the connecting plate 47, in the embodiment, the cutting knife seat 5 is arranged in a rectangular parallelepiped shape, and a placement hole penetrating through the cutting knife seat 5 is arranged on the left and right end faces of the cutting knife seat 5, the cutting knife 51 is inserted into the hole, and a locking bolt is arranged on the top of the cutting knife seat 5 to clamp the cutting knife 51.

[0026] Considering that the cylinder is mostly single-formed, the price of the adjustable stroke cylinder is high, and the height of the plastic barrel 2 is variable, therefore, in the embodiment, the connecting column 48 is a bolt, the connecting column 48 is arranged through the cutter seat 5, of course, a hole is also formed on the cutting knife 51, a nut 49 is sleeved on the connecting column 48, and the nut 49 is arranged at the upper and lower ends of the cutter seat 5. In this way, the height is fixed by using the arrangement of the double nuts 49, and meanwhile, adjustment is also facilitated. In addition, the hole is formed on the cutting knife 51, and the insertion distance of the cutting knife 51 is also limited, and the later installation is facilitated.

[0027] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
