Description

Technical Field

[0001] The present application relates to the technical field of tablet press safety mechanisms, and in particular to a potassium superoxide tablet press with a safety mechanism. Background Art

[0002] Potassium superoxide is an inorganic compound with the chemical formula KO2. It is a primary oxidant and is mainly used for emergency rescue in coal mines. The finished potassium superoxide prepared by chemical processes is generally in powder form. In order to facilitate packaging and use, tablet pressing equipment is sometimes used to press the powdered potassium superoxide, and the pressed finished product is convenient for use. Tablet presses are mainly used in tablet process research in the pharmaceutical industry. Tablet presses are automatic continuous production equipment that presses granular materials into round, special-shaped, and text, symbol, and graphic tablets with a diameter of no more than 13mm.

[0003] Existing tablet presses generally use hydraulic equipment to drive a plate to squeeze powdered raw materials to form agglomerated sheets. Based on this type of equipment operation, if a worker accidentally puts his hand into the working range of the tablet press during the operation of the equipment, it may cause personal injury. It is necessary to add a mechanism that can play a safety protection role to the tablet press to ensure that it can protect the operator when he makes a mistake. Therefore, in response to the above problem, a potassium superoxide tablet press with a safety mechanism is proposed. Utility Model Content

[0004] In view of the deficiencies of the prior art, the present application provides a potassium superoxide tablet press with a safety mechanism, which overcomes the deficiencies of the prior art and aims to solve the problem that the tablet press lacks measures to provide safety protection against improper operation by operators.

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0006] A potassium superoxide tablet press with a safety mechanism comprises a tablet press body and an induction circuit processing box, wherein induction mechanisms are fixedly installed at the edge corners of the operating table of the tablet press body, the induction mechanism comprises a fixed card shell, and mounting plates are fixedly arranged on two mutually perpendicular side surfaces of the fixed card shell, an active infrared detector transmitter is detachably mounted on one mounting plate, and an active infrared detector receiver is detachably mounted on the other mounting plate, a fastening structure is arranged on the lower end surface of the fixed card shell, and a signal transmission line is electrically connected to the active infrared detector transmitter and the active infrared detector receiver.

[0007] By adopting the above technical scheme, several groups of active infrared detector transmitters and active infrared detector receivers can be fixed at the corners of the tablet press body operating table through the combination of the fixed card shell and the fastening structure, and then the four sides of the tablet press body operating table are simultaneously sensed and detected by the active infrared detector transmitter and the active infrared detector receiver through the pairing work, and a closed rectangular detection area is formed to separate the danger zone and the safety zone. When the operator extends his hand to the working area of ​​the tablet press body during the operation of the tablet press body, the hand will inevitably pass through the induction connection line between the active infrared detector transmitter and the active infrared detector receiver on one side and be sensed. At this time, the induction circuit processing box can send the induction signal to the tablet press body to stop it from working, so as to avoid personal injury.

[0008] As a preferred technical solution of the present application, the active infrared detector transmitter fixedly installed on one of the sensing mechanisms is directly opposite to the active infrared detector receiver fixedly installed on the adjacent sensing mechanism, and the above-mentioned active infrared detector transmitter and active infrared detector receiver are of the same model and can be paired with each other to work normally.

[0009] By adopting the above technical solution, it can be ensured that each side of the tablet press body operating table has a set of sensing structures composed of a pair of active infrared detector transmitters and active infrared detector receivers, thereby ensuring that each side of the tablet press body operating table can perform independent sensing detection work.

[0010] As a preferred technical solution of the present application, a processing circuit board is fixedly arranged at the upper position inside the induction circuit processing box, and a wiring port is electrically connected to the processing circuit board. The processing circuit board is electrically connected to the active infrared detector transmitter and the active infrared detector receiver by inserting signal transmission lines into the wiring ports respectively.

[0011] By adopting the above technical solution, the sensing signals of the active infrared detector transmitter and the active infrared detector receiver can be transmitted to the processing circuit board, and the feedback signals are processed by the processing circuit board and transmitted to the tablet press body.

[0012] As a preferred technical solution of the present application, a feedback signal line is electrically connected to the processing circuit board, and the other end of the feedback signal line extends out of the induction circuit processing box and is electrically connected to the control circuit of the tablet press body.

[0013] By adopting the above technical solution, the processing circuit board can transmit the feedback signal to the control circuit of the tablet press body through the feedback signal line, so that when the processing circuit board receives an abnormal signal, it can timely feedback to the tablet press body to make it stop working immediately.

[0014] As a preferred technical solution of the present application, a buzzer is fixedly installed in the induction circuit processing box below the processing circuit board, the buzzer and the processing circuit board are electrically connected through a wire, and dense through holes are opened on the plate body at the front end surface of the induction circuit processing box where the buzzer is installed.

[0015] By adopting the above technical solution, when the processing circuit board receives an abnormal signal, the buzzer can be synchronously controlled to emit an alarm sound, reminding the staff to pay attention to their own incorrect operating behaviors.

[0016] As a preferred technical solution of the present application, the fastening structure includes a threaded sleeve fixedly arranged on the lower end surface of the fixed housing, a fastening bolt is threadedly connected in the threaded sleeve, and a contact gasket is rotatably connected to the end of the fastening bolt.

[0017] By adopting the above technical solution, the fastening bolt can be turned to squeeze the contact gasket into close contact with the lower end surface of the tablet press body operating table, thereby achieving fixed installation of the entire sensing mechanism through friction.

[0018] As a preferred technical solution of the present application, the contact gasket is a rubber sheet structure with a soft texture and dense protruding particles are fixedly arranged on its outer surface.

[0019] By adopting the above technical solution, the friction between the contact gasket and the lower end surface of the tablet press body operating table can be increased by increasing the roughness of the contact surface, thereby further improving the firmness of the installation of the sensing mechanism.

[0020] As a preferred technical solution of the present application, a hard support plate is fixedly connected between the lower end surface of the mounting plate and the side surface of the fixed housing.

[0021] By adopting the above technical solution, it is possible to support the mounting plate in the cantilever structure and prevent it from being deformed after bearing load for a long time.

[0022] The beneficial effects of the present application are as follows: a closed rectangular detection area can be formed on the four sides of the tablet press body operating table by combining a plurality of groups of active infrared detector transmitters and active infrared detector receivers to separate the danger zone and the safety zone; when the operator extends his hand toward the tablet press body working area during the operation of the tablet press body, the hand will inevitably pass through the induction connection line between the active infrared detector transmitter and the active infrared detector receiver on one side and be sensed; at this time, the induction circuit processing box can send an induction signal to the tablet press body to stop it from working, thereby avoiding personal injury.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] Reference Figure 1-3A potassium superoxide tablet press with a safety mechanism comprises a tablet press body 1 and an induction circuit processing box 6. The edge corners of the operation table of the tablet press body 1 are fixedly installed with an induction mechanism 2. The induction mechanism 2 comprises a fixed card shell 21. Two mutually perpendicular sides of the fixed card shell 21 are fixedly provided with mounting plates 22. An active infrared detector transmitter 31 is detachably mounted on one mounting plate 22, and an active infrared detector receiver 32 is detachably mounted on the other mounting plate 22. A fastening structure 4 is arranged on the lower end surface of the fixed card shell 21. The active infrared detector transmitter 31 and the active infrared detector receiver 32 are electrically connected with a signal transmission line 5. The fixed card shell 21 and the fastening structure 4 can work in combination to connect several groups of active infrared detectors. The detector transmitter 31 and the active infrared detector receiver 32 are fixed at the corners of the operating table of the tablet press body 1, and then the active infrared detector transmitter 31 and the active infrared detector receiver 32 work in pairs to simultaneously sense and detect the four sides of the operating table of the tablet press body 1, and thereby enclose a closed rectangular detection area to separate the danger zone and the safety zone. When the operator extends his hand to the working area of ​​the tablet press body 1 during the operation of the tablet press body 1, the hand will inevitably pass through the induction connection line between the active infrared detector transmitter 31 and the active infrared detector receiver 32 on one side and be sensed. At this time, the induction circuit processing box 6 can send an induction signal to the tablet press body 1 to stop it from working, thereby avoiding personal injury.

[0033] Reference Figure 2 , an active infrared detector transmitter 31 fixedly installed on one of the sensing mechanisms 2 is directly opposite to an active infrared detector receiver 32 fixedly installed on the adjacent sensing mechanism 2, and the above-mentioned active infrared detector transmitter 31 and active infrared detector receiver 32 are of the same model and can be paired with each other to work normally. By adopting the above-mentioned technical scheme, it can be ensured that each side of the operating table of the tablet press body 1 has a set of sensing structures composed of a pair of active infrared detector transmitters 31 and active infrared detector receivers 32, thereby ensuring that each side of the operating table of the tablet press body 1 can perform independent sensing detection work.

[0034] Reference Figure 4 A processing circuit board 61 is fixedly arranged at the upper position inside the induction circuit processing box 6, and a wiring port 62 is electrically connected to the processing circuit board 61. The processing circuit board 61 and the active infrared detector transmitter 31 and the active infrared detector receiver 32 are electrically connected by inserting the signal transmission line 5 into the wiring port 62. By adopting the above technical solution, the sensing signals of the active infrared detector transmitter 31 and the active infrared detector receiver 32 can be transmitted to the processing circuit board 61, and the feedback signal formed by the processing of the processing circuit board 61 is transmitted to the tablet press body 1.

[0035] Reference Figure 4 A feedback signal line 63 is electrically connected to the processing circuit board 61, and the other end of the feedback signal line 63 extends out of the induction circuit processing box 6 and is electrically connected to the control circuit of the tablet press body 1. By adopting the above technical solution, the processing circuit board 61 can transmit the feedback signal to the control circuit of the tablet press body 1 through the feedback signal line 63, so that when the processing circuit board 61 receives an abnormal signal, it can promptly feedback to the tablet press body 1 to make it stop working immediately.

[0036] Reference Figure 4 A buzzer 64 is fixedly installed below the processing circuit board 61 in the sensing circuit processing box 6. The buzzer 64 is electrically connected to the processing circuit board 61 through a wire. Dense through holes are opened on the plate body at the front end of the sensing circuit processing box 6 where the buzzer 64 is installed. By adopting the above technical solution, when the processing circuit board 61 receives an abnormal signal, the buzzer 64 can be synchronously controlled to emit an alarm sound to remind the staff to pay attention to their own incorrect operating behaviors.

[0037] Reference Figure 5-6 The fastening structure 4 includes a threaded sleeve 41 fixedly arranged on the lower end surface of the fixed card shell 21, and a fastening bolt 42 is threadedly connected in the threaded sleeve 41. The end of the fastening bolt 42 is rotatably connected to a contact gasket 43. By adopting the above technical scheme, the fastening bolt 42 can be screwed to squeeze the contact gasket 43 and make close contact with the lower end surface of the operating table of the tablet press body 1, so as to achieve fixed installation of the entire sensing mechanism 2 through friction. In particular, the contact gasket 43 is a rubber sheet structure with a soft texture and its outer surface is fixedly provided with dense convex particles. This structural form can increase the friction between the contact gasket 43 and the lower end surface of the operating table of the tablet press body 1 by increasing the roughness of the contact surface, thereby further improving the firmness of the installation of the sensing mechanism 2.

[0038] Reference Figure 6 A hard support plate 23 is fixedly connected between the lower end surface of the mounting plate 22 and the side surface of the fixed card shell 21. By adopting the above technical scheme, the mounting plate 22 in the cantilever structure can be supported to prevent it from being easily deformed after bearing load for a long time.

[0039] Working principle: by fixing the card shell 21 and the fastening structure 4, several groups of active infrared detector transmitters 31 and active infrared detector receivers 32 are fixed at the corners of the operating table of the tablet press body 1, and then the active infrared detector transmitter 31 and the active infrared detector receiver 32 are paired to simultaneously sense and detect the four sides of the operating table of the tablet press body 1, and thereby enclose a closed rectangular detection area to separate the danger zone and the safety zone. When the operator extends his hand to the working area of ​​the tablet press body 1 during the operation of the tablet press body 1, the hand will inevitably pass through the induction connection line between the active infrared detector transmitter 31 and the active infrared detector receiver 32 on one side and be sensed. At this time, the abnormal signal can be transmitted to the processing circuit board 61 through the signal transmission line 5. The processing circuit board 61 can process the abnormal signal generated by the induction into a feedback signal and transmit it to the control circuit of the tablet press body 1 through the feedback signal line 63. The tablet press body 1 stops working immediately at this time to avoid personal injury.
