Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, in particular to a carton processing and punching device. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Various processing equipment is needed for carton processing. Punching operations are inevitable during carton processing. Punching of carton requires a punching device. In order to improve the accuracy of punching, the carton needs to be fixed. However, the existing punching device is not convenient for users to fix the carton, which wastes a lot of user time and reduces the working efficiency of the punching device. If the holes in the carton are different in size, it is necessary to change the carton puncher with a larger aperture, which is very troublesome and reduces the working efficiency. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a carton processing and punching device to solve the above-mentioned problems.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a carton processing punching device, including a power head driven by a hydraulic mechanism, a fixed frame fixed on an external frame and a punch switching frame, the fixed frame is slidably sleeved on the surface of the power head, the inner cavity of the punch switching frame is slidably connected with a plurality of punch frames, the bottoms of the plurality of punch frames are fixedly connected with punches of different sizes, the inner cavity of the punch switching frame located below the power head is slidably connected with a lifting plate, the inner cavity of the punch switching frame is fixedly connected with a reset spring, the top of the reset spring is fixedly connected to the bottom of the lifting plate, the bottom of the lifting plate abuts against the bottom of the punch switching frame, the top of the punch frame is provided with a slot adapted to the surface of the power head, and different punches can be moved when in use. The punch rack of the required size is placed on the punch switching rack and slides on the punch switching rack. After the punch rack is slid under the power head, the driving cylinder drives the limit rod to move downward and is inserted into the limit groove on the surface of the punch rack to position the punch rack so that it is directly under the power head. When in use, the power head moves downward and is inserted into the slot in the punch rack. Then the punch rack is pressed down to compress the lifting plate and the reset spring downward for punching. After use, the reset spring drives the lifting plate to reset and drives the punch rack to reset. When a different punch needs to be replaced, it is only necessary to pull out the limit rod and then move the punch rack of the required size to the bottom of the punch. The limit rod is used to limit the position, so that the punch can be quickly switched. The operation is convenient and simple to use.

[0005] As a further solution of the utility model: the top of the punch switching frame is fixedly connected with a baffle located above the lifting plate. The baffle is arranged above the lifting plate to prevent the lifting plate from rising above the plane of the punch switching frame, thereby playing an effective limiting role.

[0006] As a further solution of the utility model: a limiting rod driven by a cylinder is slidably connected to the surface of the fixing frame, and a limiting groove adapted to the surface of the limiting rod is formed on the top of the punch frame.

[0007] As a further solution of the utility model: two lifting plates are provided and are symmetrically distributed on both sides of the punch switching frame.

[0008] Compared with the prior art, the utility model has the following beneficial effects: when different punches need to be replaced, only the limit rod needs to be pulled out, and then the punch rack of the required size is moved under the punch, and the limit rod is used to limit the position, so the punch can be quickly switched, which is easy to operate and simple to use.
