Detailed implementation manners

[0025] The following further elaborates on this application Figure 1-4 in conjunction with the accompanying drawings.

[0026] An embodiment of this application discloses a protection mechanism for a rotary press. Referring to Figure 1-4 , a protection mechanism for a rotary press includes a base 1. A number of machine platform supports 2 for supporting the rotary press are installed on the base 1. Two protective covers 3 are sleeved on each of the number of machine platform supports 2. The protective cover 3 includes a C - shaped plate 301 with bolt holes. The C - shaped plate 301 is installed on the machine platform support 2 through bolts. On both sides of the C - shaped plate 301, a cover body state monitoring component 4 is installed. The cover body state monitoring component 4 includes a transmitting unit 401 installed on the C - shaped plate 301. A receiving unit 402 is installed directly below the transmitting unit 401 on the base 1, which is used to monitor the state and position of the protective cover 3. The receiving unit 402 is electrically connected to the control terminal of the rotary press. By judging the on - off of the signal transmission between the receiving unit 402 and the transmitting unit 401, it is determined whether the protective cover 3 is abnormal, and then the control terminal controls whether the rotary press stops;

[0027] By adopting the above - mentioned technical solution, when dealing with the abnormality of the rotary press, it is necessary to first remove the corresponding protective cover 3, so that the receiving unit 402 cannot detect the light of the transmitting unit 401, and the control terminal controls the rotary press to stop, ensuring the production operation regulations of "stop first and then deal with the abnormality", which can effectively ensure the safety of the operators and improve the safety performance of the machine platform after use.

[0028] Referring to Figure 2 , a baffle 302 is installed inside the C - shaped plate 301. The baffle 302 is located outside the machine platform support 2 to realize the shielding of the loading and unloading direction of the rotary press. The protective cover 3 is made of a lightweight transparent material.

[0029] Referring to Figure 3, the transmitting unit 401 includes a housing one 4011 installed on the C-shaped plate 301. An installation groove is provided inside the housing one 4011, and a photoelectric sensor transmitting end 4012 is installed in the installation groove for transmitting photoelectric signals.

[0030] Refer to Figure 4 , the receiving unit 402 includes a housing two 4021 installed on the base 1. A groove is provided inside the housing two 4021, and a photoelectric sensor receiving end 4022 is installed in the groove for receiving the signal transmitted by the photoelectric sensor transmitting end 4012. Above the photoelectric sensor receiving end 4022 in the groove, a refraction lens 4023 is installed for refracting the light emitted by the photoelectric sensor transmitting end 4012 to focus it on the photoelectric sensor receiving end 4022, avoiding the deviation between the photoelectric sensor transmitting end 4012 and the photoelectric sensor receiving end 4022 caused by the vibration generated during the operation of the rotary press, resulting in the inability to receive the signal and causing false triggering.

[0031] Refer to Figure 4 , on both sides of the cover body state monitoring component 4 on the C-shaped plate 301, a conductive component 5 is installed. The conductive component 5 includes a connection unit 501 and a conductive unit 502;

[0032] Among them, the connection unit 501 is installed on the C-shaped plate 301. The connection unit 501 includes a fixed seat 5011 installed on the C-shaped plate 301, and a guide post 5012 is installed at the lower end of the fixed seat 5011;

[0033] The conductive unit 502 includes a sleeve 5021 on the base 1. The sleeve 5021 is installed directly below the guide post 5012. A conductive ring 5022 is sleeved on the guide post 5012, and the sleeve 5021 is fixedly connected to the conductive ring 5022 to achieve the rapid separation and installation of the protective cover 3. Through the interference fit between the guide post 5012 and the conductive ring 5022, power is supplied to the photoelectric sensor transmitting end 4012, which can avoid the power failure of the photoelectric sensor transmitting end 4012 caused by the vibration generated during the operation of the rotary press, resulting in false triggering.

[0034] The implementation principle of a protective mechanism for a rotary press in an embodiment of the present application is as follows: Align the guide post 5012 with the conductive ring 5022, and align the first housing 4011 with the second housing 4021. Fix the U-shaped plate 301 to the machine stand bracket 2 to complete the assembly of the protective cover 3. The light-emitting end 4012 of the photoelectric sensor emits light to the light-receiving end 4022 of the photoelectric sensor, and the light-receiving end 4022 of the photoelectric sensor receives it. The rotary press can be started according to the normal operation process. During operation, the staff can observe the operation status of the rotary press through the protective cover 3. When the rotary press operates abnormally, the staff removes the fixing bolts of the U-shaped plate 301, then lifts and removes the U-shaped plate 301, causing the guide post 5012 to move upward and separate from the conductive ring 5022. The light-emitting end 4012 of the photoelectric sensor is powered off, and the light-receiving end 4022 of the photoelectric sensor does not receive the signal from the light-emitting end 4012 of the photoelectric sensor. At this time, the control terminal controls the rotary press to stop running, ensuring the production operation regulations of "stop first and then handle the abnormality", and effectively enabling the staff to handle the abnormality online.

[0035] Finally, several points should be noted: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. It can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be directly connected. "Up", "down", "left", "right", etc. are only used to represent the relative position relationship. When the absolute position of the object being described changes, the relative position relationship may change;

[0036] Second: In the drawings of the disclosed embodiments of the present utility model, only the structures related to the disclosed embodiments are involved. Other structures can refer to the general design. Without conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;

[0037] Finally: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
