[0016] In order to make the purpose, technical scheme and advantages of the application more clear, the technical scheme of the application will be described in detail below in combination with the specific embodiments of the application and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0017] The technical scheme provided by each embodiment of the application will be described in detail below in combination with the drawings.

[0018] In order to ensure that the adjusted production parameters do not change, prevent human factors from interfering with the state of the adjusting hand wheel, after the working parameters of the tablet press are adjusted, a protective cover is added to the hand wheel, an electronic lock is installed on the protective cover, the opening of the electronic lock is controlled through the touch screen, only authorized personnel can enter the touch screen through password verification, after entering, the electronic lock is opened, the protective cover can be opened, and the hand wheel is adjusted.

[0019] According to the feedback of the user of the tablet press with the hand wheel adjustment, the position of the hand wheel is easy to be changed during the working process, especially when the tablet press is cleaned at the end of the production day, which leads to the need to recheck the adjustment parameters when producing the same tablet, wasting time, and therefore it is hoped that the state of the adjusted hand wheel can be guaranteed, and the hand wheel remains in the original state after adjustment and cannot be interfered by human factors. When the hand wheel needs to be adjusted, the personnel must be authorized to operate. Therefore, a protective cover is designed on the hand wheel, and a solenoid electronic lock is provided on the protective cover. Only authorized personnel can open the lock through the touch screen decoding and set or modify the tablet parameters through the hand wheel.

[0020] The existing tablet press, taking a double-discharge tablet press as an example, has, from left to right on the operating table of the tablet press, a filling hand wheel for controlling the state of discharging on the right side, a pre-pressing hand wheel, a tablet thickness hand wheel, and a tablet thickness hand wheel for controlling the state of discharging on the left side, a pre-pressing hand wheel, and a filling hand wheel. The arrangement of each hand wheel is as shown in Figure 1 .

[0021] The tablet thickness hand wheel, also known as the pressure hand wheel, is used to adjust the distance between the upper and lower main pressing wheels, thereby adjusting the pressure applied to the tablet.

[0022] The pre-pressing hand wheel is used to adjust the distance between the upper and lower pre-pressing wheels, thereby adjusting the pre-pressing force.

[0023] The filling hand wheel is used to adjust the filling depth and filling amount, thereby ensuring the weight of the tablet.

[0024] Figure 2 A kind of adjusting hand wheel protective cover structure provided for the embodiment of the present application, for tablet press, include cover body 11 and electronic lock 12.

[0025] One side of the cover body is movably connected with the frame plane of the tablet press, including an open state and a closed state, and the hand wheel arranged on the plane is buckled in the closed state.

[0026] Preferably, the cover body includes an upper surface, a front surface, a lower surface and a side surface. The upper surface, the front surface, the lower surface and the side surface form a back surface opening cylindrical hollow cavity.

[0027] Since the tablet press includes multiple hand wheels, the hand wheels are usually arranged above the touch screen of the tablet press.

[0028] For example, the tablet press frame above the touch screen has a planar structure perpendicular to the horizontal plane, and the handwheels are arranged horizontally on the planar structure, and the cover body preferably has an upper surface, a front surface, a lower surface and a side surface to form a hollow cylindrical cavity with an opening on the back surface. The hollow cylindrical cavity accommodates the handwheels through the inner opening, and when the cover body is buckled on the planar structure on the tablet press frame, all the handwheels are covered inside.

[0029] Further, the upper surface near the back side is swing-connected to the planar structure on which the handwheels are arranged on the tablet press frame through a hinge 13. The cover body swings up and down through the hinge, swings upward to an open state, and swings downward to the lower surface near the back side to be attached to the planar structure, and the cover body is in a closed state.

[0030] For example, the cover body is made of organic glass material, which is light and transparent. The cover body has a handle 14 in the middle, which is supported by an air spring installed on the side of the control cabinet when opened.

[0031] Therefore, preferably, an air spring 15 is further included, one end of which is arranged on the side of the cover body perpendicular to the rotation direction, and the other end is arranged on the tablet press frame. The air spring provides an opening-tending force when the cover body is opened to a set angle or when the cover body is closed to a set angle.

[0032] For example, the cover body swings up and down in the direction perpendicular to the horizontal plane to complete opening and closing. As shown in Figure 3 For example, one end of the air spring is connected to the side of the cover body, and the other end is connected to the side of the tablet press frame, such as the side of the control cabinet, and the cover body swings in an arc, and when the cover body is opened from the closed state to more than half of the arc, or when the cover body is closed from the maximum open state to half of the arc. The air spring provides a support force, i.e. an opening-tending force, or a closing-resisting force.

[0033] The electronic lock is arranged on the planar structure, and the electronic lock has a plug 121 inside which extends or retracts by losing power or being powered. When the cover body is in a closed state, a plug hole 122 arranged on the cover body is opposite to the plug of the electronic lock.

[0034] The plug of the electronic lock is accommodated by the plug hole.

[0035] Further, an electronic lock controller is further included for controlling the on-off of the electronic power supply. Pressing the electronic lock controller loses power of the electronic lock, and the plug extends. Releasing the electronic lock controller powers on the electronic lock, and the plug retracts.

[0036] The electronic lock adopts a solenoid type electronic lock, as shown in Figure 2 The electronic lock is installed on the side of the right cover, and the plug on the electronic lock cooperates with the plug hole on the inner wall of the right side of the cover, as shown in Figure 4As shown, when the touch screen electronic lock control button is pressed, the electronic lock is powered and the bolt 121 is retracted, at which time the protective cover can be opened; when the touch screen electronic lock control button is pressed again, the electronic lock is powered off and the bolt is extended, and the protective cover can be locked.

[0037] The above only shows the embodiments of the present application and is not intended to limit the present application. Various modifications and changes can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
