Description

Technical Field

[0001] This utility model relates to the field of dry granulation machines, and in particular to a rotating connection structure for the operation screen of a dry granulation machine. Background Technology

[0002] Dry granulation machines generally consist of a granulator housing and a controller control panel. Currently, most controller control panels are connected to the housing via a U-shaped connecting rod, such as Chinese patents CN220878770U (a dry granulation machine for drug processing), CN212595553U (a high-sealing dry granulation machine extrusion sealing structure), and CN219186815U (a dry granulation machine). In these three patents, the connection structure between the controller control panel and the housing is basically the same: the controller control panel is located on one side of the housing, and the two are connected by a U-shaped connecting rod. One end of the U-shaped connecting rod connects to the top of the housing, and the other end connects to the top of the controller control panel. Because the controller control panel is relatively heavy, over time, this connection structure can cause deformation at the top of the housing due to gravity, leading to the controller control panel sagging. Furthermore, this connection structure makes wiring and maintenance very inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a rotating connection structure for the operating screen of a dry granulation machine.

[0004] The innovation of this utility model is that the rotating structure of this application is simple, practical and easy to thread and maintain, and can avoid the sagging of the operating screen and the deformation of the chassis wall.

[0005] To achieve the aforementioned objectives, the technical solution of this utility model is as follows:

[0006] A rotating connection structure for the operating screen of a dry granulation machine includes a chassis and an operating screen, and further includes an upper shell, a lower shell, and a middle shell. The right sides of the upper and lower shells are connected to the left side wall of the chassis. An upper through hole is provided between the upper shell and the chassis, and a lower through hole is provided between the lower shell and the chassis. The middle shell is disposed between the upper and lower shells, and its left side is connected to the right side wall of the operating screen. An upper straight pipe is provided at the top right side of the middle shell, and a lower straight pipe is provided at the bottom right side. The upper straight pipe is rotatably connected to the bottom of the upper shell, and the lower straight pipe is rotatably connected to the top of the lower shell.

[0007] Furthermore, a diagonal brace is provided below the lower shell, one side of which is connected to the chassis, and a diagonal brace is provided between the diagonal brace and the bottom of the free end of the operation screen. The diagonal brace and the diagonal brace are rotatably connected.

[0008] Furthermore, the middle shell is also provided with an inspection hole, and a cover plate is provided on the inspection hole.

[0009] Furthermore, a protective rubber ring is provided at the upper or lower perforation.

[0010] Furthermore, a rubber plug is provided at the upper or lower perforation.

[0011] The beneficial effects of this utility model are:

[0012] First: The design includes an upper straight pipe and a lower straight pipe, which facilitates rotation and allows for wire threading. The rotating structure is simple and practical.

[0013] Second: It is equipped with top through holes, bottom through holes and inspection holes. Depending on the actual situation, the cable can be routed through the top through holes or the bottom through holes, or both top and bottom through holes can be routed at the same time. The cable routing method is flexible and the inspection and maintenance are convenient.

[0014] Third: Installing diagonal braces can prevent the control panel from sagging and the side walls of the chassis from deforming.

[0015] Fourth: Installing a protective rubber ring can prevent the wire from being scratched. Attached Figure Description

Detailed Implementation

[0019] The technical solutions in the embodiments of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0020] A rotating connection structure for the operating screen of a dry granulation machine includes a machine housing 10 and an operating screen 20, and further includes an upper shell 30, a lower shell 40, and a middle shell 50. The right sides of the upper shell 30 and the lower shell 40 are connected to the left side wall of the machine housing 10. An upper through hole 11 is provided between the upper shell 30 and the machine housing 10, and a lower through hole 12 is provided between the lower shell 40 and the machine housing 10. The middle shell 50 is disposed between the upper shell 30 and the lower shell 40. The left side of the middle shell 50 is connected to the right side wall of the operating screen 20. An upper straight pipe 51 is provided at the top right side of the middle shell 50, and a lower straight pipe 52 is provided at the bottom right side. The upper straight pipe 51 is rotatably connected to the bottom of the upper shell 30, and the lower straight pipe 52 is rotatably connected to the top of the lower shell 40.

[0021] Furthermore, the rotatable connection structure between the upper straight pipe 51 and the bottom of the upper shell 30 is existing technology. It can be rotated by a bearing or by other means, which will not be elaborated here.

[0022] Furthermore, the rotatable connection structure between the lower straight pipe 52 and the top of the lower shell 40 is existing technology. It can be rotated by a bearing or by other means, which will not be elaborated here.

[0023] Furthermore, a diagonal brace 60 is provided below the lower shell 40. One side of the diagonal brace 60 is connected to the chassis 10. A diagonal brace 61 is provided between the diagonal brace 60 and the bottom of the free end of the operation screen 20. The diagonal brace 61 and the diagonal brace 60 are rotatably connected. This rotatable connection structure is also existing technology. It can be rotated by a bearing or by a rotating structure of a shaft and a shaft hole. It will not be described in detail here.

[0024] Furthermore, the middle shell 50 is also provided with an inspection hole, and a cover plate 53 is provided on the inspection hole.

[0025] Furthermore, a protective rubber ring 70 is provided at the upper perforation 11 or the lower perforation 12.

[0027] When wiring this application:

[0028] The wires are led out from the dry granulator housing 10. Depending on the requirements, they can enter the upper shell 30 or the lower shell 40 through the upper through hole 11 or the lower through hole 12, and then enter the middle shell 50 through the upper straight pipe 51 or the lower straight pipe 52, and finally connect to the operation screen 20. Of course, the upper through hole 11 and the lower through hole 12 can also be used for wiring at the same time. The edges of the through holes that need to be wired are fitted with protective rubber rings 70 to prevent the edges of the through holes from scratching the wires when the operation screen 20 rotates. Rubber plugs 71 are set at the through holes that do not need to be wired.

[0029] When the machine is shut down for maintenance, simply open the cover 53, and if necessary, open the chassis 10 to perform the inspection and maintenance.
