Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] This utility model discloses an automatic control dustproof door device for a tablet press, referring to... Figure 1 , Figure 2 and Figure 5 It includes a platen 1, a housing 3, which is concave and installed on the top surface of the platen 1; two side supports 8, which are respectively installed at both ends of the top surface of the housing 3; a dustproof mechanism, which is installed between the two side supports 8; the dustproof mechanism, the side supports 8 and the housing 3 cooperate with each other to prevent dust from leaking out when the tablet press on the platen 1 is working; and a base frame 2, which is installed on the bottom surface of the platen 1.

[0030] The dustproof mechanism includes two guide slides 12, which are respectively opened on the opposite side walls of the two side supports 8. The first door panel 4 is installed between the two side supports 8 at one end via a round rod 17. The second door panel 5 is connected to the other end of the first door panel 4 at one end via a round rod 17. Two rollers 18 are respectively set inside the two guide slides 12. The two rollers 18 are respectively sleeved on both ends of the round rod 17 that passes through the other end of the second door panel 5. It also includes a rectangular opening 6, which is opened through the second door panel 5. A transparent glass 7 is installed in the rectangular opening 6. The first door panel 4 and the second door panel 5 are configured to be connected to each other for sealing or opening the inside of the tablet press to the external environment.

[0031] Two electric push rods 11 drive the first door panel 4 to rotate around the round rod 17 connected to the two side supports 8. The rotation of the first door panel 4 drives the second door panel 5 to move through the round rod 17, so that the second door panel 5 drives the round rod 17 to slide along the guide slide 12 with the rollers 18 at both ends of the rod 17 inside the guide slide 12. This realizes the opening and closing of the dustproof door formed by the combination of the first door panel 4 and the second door panel 5, effectively preventing dust from flying and improving the cleanliness of the production environment.

[0032] Reference Figures 4-5Two sets of drive mechanisms are respectively installed on two side supports 8; the drive mechanisms are connected to the dustproof mechanism to realize the opening and closing action of the dustproof door. The drive mechanism includes a concave support 10 installed on the top surface of the side support 8, a movable block 9 installed inside the concave support 10 through a rotating shaft, an electric push rod 11 installed on the movable block 9, a positioning plate 15 installed on the first door panel 4, and a connecting rod 16 installed on the positioning plate 15 and connected to the output end of the electric push rod 11.

[0033] The output ends of the two electric push rods 11 drive the positioning plate 15 to move through the connecting rod 16. The movement of the positioning plate 15 drives the first door panel 4 and the second door panel 5 to move. At the same time, the electric push rods 11 drive the movable block 9 to rotate around the pivot.

[0034] It also includes a controller mechanism, which includes a support plate 19 mounted on the side wall of the machine plate 1, a rotating plate 20 mounted on the top surface of the support plate 19 via a threaded rod, a rotating table 13 mounted on the top surface of the rotating plate 20, a touch screen display 14 mounted on the rotating table 13, a sensor mounted on the inner wall of the machine housing 3, and a controller mounted inside the touch screen display 14. The touch screen display 14, the sensor, and the controller are configured to be connected in a cooperative manner. The sensor is an infrared sensor used to detect the working status of the tablet press. The controller is a programmable logic controller used to receive signals from the sensor and, according to a preset program, to issue commands through the touch screen display 14 to control the two electric push rods 11 to realize the opening and closing of the dustproof door.

[0035] When the tablet press starts working, the infrared sensor transmits the detected signal to the controller. The controller determines that the dust door needs to be closed according to the preset program and sends a command to the two electric push rods 11 through the touch screen display 14. After receiving the command, the two electric push rods 11 drive the first door plate 4 and the second door plate 5 to close to prevent dust from leaking out. When the tablet press stops working, the infrared sensor detects the signal again and transmits it to the controller to open the first door plate 4 and the second door plate 5.

[0036] It also includes a position sensor, which is installed at the lower end of the second door panel 5. The position sensor is electrically connected to the controller. The position sensor is used to detect whether the first door panel 4 and the second door panel 5 are fully open or closed, and feeds the signal back to the controller. At the same time, the result is displayed on the touch screen display 14, which improves the stability of the device.

[0037] The implementation principle of the automatic control dustproof door device for a tablet press according to this utility model embodiment is as follows: When the tablet press starts working, the infrared sensor transmits the detected signal to the controller. The controller determines that the dustproof door needs to be closed according to the preset program and sends a command to control the two electric push rods 11 through the touch screen display 14. After receiving the command, the output ends of the two electric push rods 11 drive the first door plate 4 to rotate around the round rod 17 connected to the two side supports 8 as the axis. The rotation of the first door plate 4 drives the second door plate 5 to move through the round rod 17, so that the second door plate 5 drives the round rod 17 to slide along the guide slide 12 with the rollers 18 at both ends of the round rod 17 inside the guide slide 12, thereby realizing the closing of the dustproof door formed by the combination of the first door plate 4 and the second door plate 5. The downward movement of the second door plate 5 drives the position sensor to move. The position sensor detects whether the first door plate 4 and the second door plate 5 are completely closed and feeds the signal back to the controller. At the same time, the result is displayed on the touch screen display 14, realizing the automatic control of the dustproof door without manual operation.
