Description

Technical Field

[0001] The utility model relates to the technical field of cigarette clay pressing rods, in particular to a high-position detection and blowing system for a storage bin of a pressing machine. Background Art

[0002] The automatic hydraulic rod press (such as the TG80 model) is a cigarette opium rod pressing equipment widely used by tobacco companies. It collects the opium from the process dust removal system and flows it into the storage bin of the automatic hydraulic rod press through the inclined screw conveyor and the horizontal screw conveyor. The opium level in the storage bin is detected by the detector installed on the side of the storage bin. From top to bottom, the storage bin high level detection, storage bin middle level detection, and storage bin low level detection are installed in sequence. When the corresponding opium level detection in the storage bin (storage bin low level detection and storage bin middle level detection) is triggered for a certain period of time, the TG80 automatic hydraulic rod press enters the corresponding speed mode, so the opium in the storage bin is pressed into short opium rods with appropriate length and hardness by the TG80 automatic hydraulic rod press; and the storage bin high level detection adopts a photoelectric switch, which is mainly used to control the operation of the horizontal screw conveyor.

[0003] However, during the operation of the automatic hydraulic press, since opium is stored in the storage bin, it is easy to adhere to the surface of the photoelectric switch. When the opium adhered to the surface of the photoelectric switch and accumulated to a certain extent, it will cause the photoelectric switch for detecting the high level of the storage bin to malfunction. As mentioned above, the high level detection of the storage bin of the automatic hydraulic press controls the operation of the horizontal screw conveying device. When the high level detection of the storage bin is triggered for a certain period of time, the electronic control device of the press will stop the horizontal screw conveying device.

[0004] Therefore, if during the operation of the automatic hydraulic rod press, when the high-level detection of its storage bin is triggered by false detection of opium adhesion, the horizontal screw conveyor device will stop running, while the inclined screw conveyor device is still working, which will cause the horizontal screw conveyor device to be compacted due to excessive opium, causing the protective cover of the horizontal conveyor device to be squeezed open, and the inclined screw conveyor device will trip due to motor overload, causing the rod press machine to stop working; furthermore, the horizontal screw conveyor device is more than 3 meters above the ground, and the above-mentioned fault requires high-altitude maintenance, which also brings great safety hazards.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings, in which:

[0017] Figure 1 A schematic diagram of a high-position detection and blowing system for a storage bin of a rod press provided in an embodiment of the utility model. DETAILED DESCRIPTION

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0019] The utility model proposes an embodiment of a high-position detection and blowing system for a storage bin of a rod press machine. Specifically, Figure 1 As shown, it includes: a solenoid valve 1 arranged at the automatic hydraulic rod press, a bracket 2 arranged in the material storage bin of the rod press, a compressed air source 3, a compressed air pipe 4, an original machine PLC (installed in the electric control cabinet of the rod press) and a timer;

[0020] The compressed air pipe 4 is connected to the air source 3 and the solenoid valve 1, and is fixed by the bracket 2 located above the high-position detection photoelectric switch, and the air outlet opening of the compressed air pipe 4 faces the probe surface of the high-position detection photoelectric switch;

[0021] The solenoid valve 1 and the timer are respectively connected to the original machine PLC electrical signal, and the timer is used to set the purge cycle and duration. In some preferred embodiments, the timer can be preferably implemented by a time relay.

[0022] In actual operation, the solenoid valve 1 can specifically adopt a two-position three-way valve, that is, the solenoid valve 1 has two switching states, namely open and closed, and two of the three interfaces can be connected arbitrarily, while the third interface has only one state of being connected to the other two interfaces at the same time.

[0023] In order to ensure the fixation stability of the trachea, the support 2 is preferably made of metal material, but it can also be made of non-metallic material with a certain strength.

[0024] In addition, for the consideration of different application scenarios, a purge mode switching switch SA connected to the PLC electrical signal of the original machine can be set at the electric control cabinet of the rod press machine. The purge mode switching switch SA is associated with the signal of the solenoid valve 1, and is used to switch the automatic purge mode and the manual purge mode. The switch is set at the electric control cabinet to facilitate the staff to operate on demand. It can be understood that the automatic purge mode automatically triggers the opening and closing of the solenoid valve according to the established interval cycle and purge working time, so as to realize the timed automatic purge of the high-level detection photoelectric switch; the manual purge mode can be understood as temporarily cutting off the electric control signal of the automatic purge, and the staff manually opens and closes the solenoid valve 1 as needed to realize manual purge. The manual purge mode is suitable for temporary use in special circumstances such as maintenance of the rod press machine equipment or sudden accumulation of opium on the surface of the photoelectric switch for high-level detection of the storage bin. The present invention does not make any limitation on this, but it can be supplemented based on this that the purge mode switching switch SA preferably adopts a two-position knob switch. The characteristic of this physical switch is that the knob is used to push the transmission mechanism to connect or disconnect the moving contact and the static contact, thereby realizing the conversion of electrical signals / circuits, thereby effectively meeting the switching requirements of the present invention for different cleaning modes.

[0025] To sum up, the main design concept of the utility model is that, in order to ensure that the photoelectric switch of the storage bin of the automatic hydraulic rod press can work reliably and will not cause false detection and triggering due to the attachment of opium on the surface, a set of storage bin high-position detection and cleaning system is designed on the automatic hydraulic rod press, which specifically includes a solenoid valve arranged at the automatic hydraulic rod press, a bracket arranged in the storage bin of the rod press, a compressed air source, a compressed air pipe, an original machine PLC and a timer; the compressed air pipe is connected to the air source and the solenoid valve, and is fixed by a bracket located above the high-position detection photoelectric switch, and the air outlet opening of the compressed air pipe faces the probe surface of the high-position detection photoelectric switch; the solenoid valve and the timer are respectively connected to the original machine PLC electrical signal, wherein the timer is used to set the purge cycle and duration, so as to blow off the opium attached to the surface of the high-position detection photoelectric switch of the storage bin as needed, so as to ensure the safety and stability of the storage bin feeding process.
