Description

Technical Field

[0001] The utility model belongs to the technical field of fastener manufacturing, and in particular relates to a start-stop linkage system for a powder tablet press. Background Art

[0002] The nail shooting technology is to use a nail gun to shoot nail bullets, so that the gunpowder in the bullet burns and releases energy, and the nails are directly nailed into the hard matrix. The nails are filled with gunpowder tablets, which are made by pressing gunpowder powder through a rotary tablet press. The rotary tablet press is a multi-punch tablet press developed on the basis of a single-punch tablet press that can continuously complete a series of actions such as filling, pressing, and pushing.

[0003] Since gunpowder powder is a flammable and explosive chemical, it needs to be isolated during tableting. Generally, the tablet press is set up in a separate room, and it is stipulated that no staff can be in the room when the tablet press is working. However, at present, the staff can only rely on rules and regulations to consciously abide by them, and there is a lack of other more reliable protection methods. In actual production, the staff may mistakenly enter the room where the tablet press is working, or the staff may not close the door completely, posing a safety risk. In order to improve the safety of gunpowder tablet production, this application proposes a solution to this problem. Summary of the invention

[0004] The utility model aims to provide a start-stop linkage system for a powder tablet press to ensure production safety in view of the deficiencies in the prior art.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The gunpowder powder tablet press start-stop linkage system provided by the utility model links the opening and closing of the room door with the start and stop of the tablet press. When the door is open, the tablet press is in a power-off state and stops working. The tablet press can be connected to the power supply and work only when the room door is closed, thereby eliminating safety risks.

[0017] There is a camera in the room, which can monitor the working status of the tablet press in real time through the main control system, so that the staff can deal with abnormal situations in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] like Figure 1 As shown, a start-stop linkage system for a powder tablet press includes a tablet press arranged in a room, and the tablet press is connected to a main control system; the room includes a door, a trigger mechanism is arranged on the door, a sensing mechanism is arranged on the wall where the door is located, a power line of the tablet press passes through the sensing mechanism, and a contact switch of the power line is arranged inside the sensing mechanism;

[0025] When the door is closed, the trigger mechanism is connected to the sensing mechanism and the switch is turned on; when the door is opened, the trigger mechanism is separated from the sensing mechanism and the switch is turned off.

[0026] To ensure production safety, the power line is laid underground to outside the room.

[0027] See also Figure 2-3 In some embodiments, the trigger mechanism is disposed at a corner of the door, the sensing mechanism is located at one side of the trigger mechanism, the sensing mechanism comprises a housing and an elastic shaft; the elastic shaft comprises a Z-shaped shaft and a spring, one end of the Z-shaped shaft is located inside the housing; the other end is located outside the housing, and is used for contact sensing with the trigger mechanism. The trigger mechanism is specifically a three-dimensional metal sheet welded to the door.

[0028] The switch of the power line includes a first contact and a second contact. When the two contacts are in contact, the power line is connected and the tablet press starts to work; when the two contacts are separated, the power line is disconnected and the tablet press stops working.

[0029] One end of the spring is fixed on the sensing mechanism, one end of the Z-shaped rotating shaft is located in the housing, one side of which contacts the spring, and the other side of which is provided with a first contact point; the second contact point is fixedly provided on the housing of the sensing mechanism;

[0030] When the door is closed, the trigger mechanism contacts one end of the Z-shaped shaft outside the shell, limiting the position of the Z-shaped shaft. At this time, the spring is in a stretched state, and the first contact contacts the second contact. When the door is opened, the trigger mechanism moves away from the Z-shaped shaft, and the spring contracts and recovers after losing the limiting effect. The Z-shaped shaft rotates under the action of the spring tension, and the first contact separates from the second contact.

[0031] In other embodiments, a torsion spring may be used instead of a spring to achieve the effect of automatic separation of the first contact and the second contact.

[0032] See also Figure 4 In some embodiments, a main control system is arranged outside the room, and the tablet press is connected to the main control system. The main control system can display the working status of the tablet press, and the main control system also includes a display screen.

[0033] A camera is installed in the room to capture the working status of the tablet press. The camera is electrically connected to the main control system to send the captured video images to the main control system and display them in real time on the display screen of the main control system. The staff can observe the working status of the tablet press outside the room and deal with abnormal situations in time, such as shutting down the tablet press in time when it is idling.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
