Description

Technical Field

[0001] The utility model relates to the field of empty frame cylinder blocking devices, in particular to an empty frame cylinder blocking device. Background Art

[0002] In the logistics industry, due to the diverse flow of multiple batches and products, product sorting is essential during the final delivery process. This makes item sorting particularly important. After sorting, items are placed into empty boxes. The empty boxes, along with the items, are moved to a designated location, where the items are removed and the empty boxes are refilled and returned to their original location.

[0003] A blocking cylinder, on the other hand, is designed to stop the movement of a controlled object and absorb any impact from it, thereby assisting in the operation of a controlled object moving in one direction on a conveyor or other similar machine. Typically, a blocking cylinder is installed on a conveyor belt to limit the bottom of an empty frame. This requires replacing or modifying the conveyor belt structure to install a blocking cylinder in a different position, which is cumbersome.

[0004] Therefore, in order to solve the deficiencies in the prior art, a simple-structured hollow-frame cylinder blocking device needs to be designed. Utility Model Content

[0018] Below with reference to the embodiment and the attached Figures 1-2 , the technical solution of the utility model is further elaborated.

[0019] Example 1

[0020] A hollow frame cylinder blocking device includes: a conveyor belt 1, a U-shaped bracket 2, a lifting assembly 3, a rotating cylinder 4, a baffle 5 and a buffer plate 6. The U-shaped bracket 2 is arranged at the upper end of the conveyor belt 1. The lifting assembly 3 includes a motor 31, a gear 32, a rack 33 and a lifting frame 34. The motor 31 is arranged on the U-shaped bracket 2, the gear 32 is arranged at the output end of the motor 31, the rack 33 is fixed to one side of the lifting frame 34 and is meshed with the gear 32. The rotating cylinder 4 is arranged at the lower end of the lifting frame 34, the baffle 5 is rotatably arranged at the lower end of the rotating cylinder 4, and the buffer plate 6 is elastically slidably arranged at the front end of the baffle 5.

[0021] like Figures 1 and 2 As shown, the working principle of the present invention is as follows: the U-shaped bracket 2 is set above the conveyor belt 1, and the lifting component 3, the rotating cylinder 4, the baffle 5 and the buffer plate 6 are all suspended above the conveyor belt 1. There is no need to replace or modify the conveyor belt structure. The structure is simple and easy to use. At the same time, the height of the baffle 5 can be adjusted according to the motor and the gear rack structure, and empty frames of different heights can also be blocked, which has stronger applicability; the rotating cylinder 4 selectively adjusts the rotation angle of the baffle 5 according to actual conditions to achieve blocking and passage; the buffer plate 6 at the front end of the baffle 5 can absorb the impact force of the empty frame when it contacts the empty frame.

[0022] As a further preferred embodiment, a slide 51 is provided in the baffle 5, a spring 52 is provided on the right side of the slide 51, a slide rod 61 is fixed to the right end of the buffer plate 6, and the right end of the slide rod 61 is located in the slide 51. After the buffer plate 6 releases the empty frame, it drives the slide rod 61 to move to the right until the spring 52 is compressed.

[0023] As a further preferred embodiment, a stopper 53 is threadedly connected to the left end of the slideway 51. The slide rod 61 is provided with a stopper 62 located within the slideway 51 and to the right of the stopper 53. When the baffle 5 is rotated 90 degrees counterclockwise to allow the empty frame to pass, the stopper 53 cooperates with the stopper 62 to control the maximum height to which the buffer plate 6 can fall due to gravity, thereby preventing obstruction to the passage of the empty frame.

[0024] As a further preferred embodiment, the lifting frame 34 includes an upper bracket 341, a connecting rod 342 and a guide column 343. The connecting rod 342 is arranged downward through the U-shaped bracket 2. The upper bracket 341 is located at the upper end of the U-shaped bracket 2 and is connected to the connecting rod 342. The guide column 343 is fixed to the right side of the upper end of the U-shaped bracket 2. The right end of the upper bracket 341 is slidably sleeved on the guide column 343, thereby improving the stability of the lifting frame 34 when lifting.

[0025] As a further preferred embodiment, a rubber block 63 is provided on the surface of the buffer plate 6 .

[0026] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
