Description

Technical Field

[0001] This utility model relates to the field of controller technology, and in particular to a controller for a shredder that prevents leakage when not in operation. Background Technology

[0002] Tobacco shredders are important pieces of equipment on the tobacco processing production line in tobacco factories. They are devices that cut tobacco leaves or stems into shreds of equal width. The controller of a tobacco shredder is a crucial component of the automated control system for the shredder, responsible for controlling its start-up, operation, and shutdown.

[0003] However, existing shredder controllers continuously output voltage from their power supply. As long as the power supply system is normal and there are no open circuits or other issues in the line from the power supply to the starter, the starter will have voltage input. This means that even without a start signal, the shredder controller still carries the risk of having 220V to ground, posing a significant safety hazard during maintenance and repair. Utility Model Content

[0004] This utility model provides a shredder controller that avoids leakage when not in operation, thereby solving the defect in the prior art that the shredder controller still has a 220V voltage to ground when there is no start signal. This invention avoids leakage when the shredder controller is not in operation, thus avoiding safety hazards during maintenance.

[0005] This utility model provides a controller for a shredder that avoids leakage when not in operation, including a controller housing and a control module, wherein the control module is provided on the controller housing; The control module includes a mode switching module, a signal processing module, an input / output module, and an enable bit integrated circuit module; The input / output module, mode switching module, and enable bit integrated circuit module are all electrically connected to the signal processing module. The mode switching module, signal processing module, and enable bit integrated circuit module are all located inside the controller housing; The input / output modules are located at one end of the controller housing.

[0006] In addition, the shredder controller for preventing leakage when not in operation according to this utility model may also have the following additional technical features: In some embodiments of this utility model, the control module further includes an early warning module, which is electrically connected to the signal processing module.

[0008] In some embodiments of this utility model, an insulating device is also included; The insulating device is detachably connected to the controller housing. During operation, the insulating device is used to shield the input and output modules.

[0009] In some embodiments of this utility model, the insulating device includes a folding plate and a baffle; A baffle is provided on each side of the folding plate, and the folding plate is detachably connected to the controller housing; The baffle and the folding plate work together to block the input and output modules.

[0010] In some embodiments of this utility model, the insulating device further includes a fixing block and a fastener; The fixing block is set on the surface of the controller housing.

[0026] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0027] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “” used herein may also indicate the inclusion of the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated, unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0028] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0029] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may also be rotated 90 degrees or in other orientations, and the spatial relative descriptors used in the text will be interpreted accordingly.

[0030] like Figures 1 to 8 As shown, according to an embodiment of the first aspect of the present invention, a shredder controller for preventing leakage when not in operation is proposed, comprising a controller housing 1 and a control module 11, wherein the controller housing 1 is provided with the control module 11; The control module 11 includes a mode switching module 3, a signal processing module 4, an input / output module 5, and an enable bit integrated circuit module 7; Input / output module 5, mode switching module 3, and enable bit integrated circuit module 7 are all electrically connected to signal processing module 4; The mode switching module 3, the signal processing module 4, and the enable bit integrated circuit module 7 are all located inside the controller housing 1; The input / output module 5 is located at one end of the controller housing 1.

[0031] In the above embodiments, it should be noted that the mode switching module 3, signal processing module 4, input / output module 5, and early warning module 6 respectively use the existing technology.

[0032] The mode switching module 3 is responsible for switching between different working modes of the shredder, such as manual mode, automatic mode, and debugging mode.

[0033] Its working principle involves receiving mode switching commands from the operation panel or host computer to adjust the control parameters and logic of the shredder controller to meet the operational requirements of different modes. This may involve reconfiguring parameters such as motor speed control, cutter feed speed, and material conveying speed.

[0034] Signal processing module 4 is responsible for processing and analyzing various signals received by the shredder controller, including signals detected by sensors and operation command signals.

[0035] Its working principle involves using signal processing circuits and algorithms, such as filtering the signal with filters, amplifying the signal with amplifiers, and converting the analog signal into a digital signal using an analog-to-digital converter. Then, digital signal processing algorithms are used to analyze and process the signal to extract useful information.

[0036] Input / output module 5 serves as the interface between the shredder controller and external devices, enabling signal input and output.

[0037] Its working principle involves using opto-isolation or electromagnetic isolation technology to isolate external signals from the controller's internal circuitry, preventing external interference signals from entering the controller and protecting it from external high voltage and high current. The output module then uses power devices such as relays, transistors, and thyristors to convert the controller's weak electrical signals into strong electrical signals capable of driving the actuators.

[0038] The enable bit integrated circuit module 7, employing existing technology, functions as a control switch. It determines whether the entire integrated circuit module or certain parts thereof operates by receiving specific control signals. Specifically, the enable bit integrated circuit module 7 contains corresponding logic circuits that judge and process the input control signals. When the enable signal is valid, the internal logic circuits control the operating state of other circuit units within the enable bit integrated circuit module 7 based on the state of the input signal, such as opening or closing signal paths, starting or stopping data processing, etc. The technical effects achieved by the above embodiments are as follows: First, by setting the enable bit integrated circuit module 7, more precise control logic can be provided for this controller. If the signal processing module 4 of this controller does not process the start signal accurately enough, resulting in voltage output when there is no start signal, then by adding the enable bit integrated circuit module 7, the relevant circuit can be strictly cut off and the voltage output can be prevented when no correct start signal is received through its set logic, thus solving the problem from the logic control level.

[0039] Secondly, the enable bit integrated circuit module 7 can serve as a signal isolation and enhancement mechanism. If the original controller's start signal is interfered with, causing signal disorder and abnormal voltage when there is no signal, the enable bit integrated circuit module 7 can isolate the signal, reduce interference, and enhance the strength and stability of the start signal. This ensures that the starter only works when a valid start signal is received, thereby avoiding voltage problems when there is no start signal. This also prevents leakage when the shredder controller is not working, thus avoiding safety hazards during maintenance.

[0040] Optional, such as Figures 1 to 4 , Figure 7 and Figure 8 As shown, the control module 11 also includes an early warning module 6, which is electrically connected to the signal processing module 4.

[0041] In the above optional embodiments, it should be noted that the early warning module 6 adopts the early warning module of the prior art. Its main function is to monitor the operating status of the shredder in real time, and issue an early warning signal in a timely manner when an abnormal situation is detected, so as to remind the operator to take corresponding measures to avoid equipment failure or production accident.

[0042] Its working principle is to acquire the operating parameters and status information of the shredder through connection with sensors and signal processing module 4. Using preset thresholds and algorithms, this information is analyzed and judged. When parameters exceed the threshold or abnormal conditions occur, warning signals are issued through audible and visual alarms, SMS notifications, and displays on the host computer. The beneficial effects of the above optional embodiments are as follows: the operation of the shredder can be further detected by setting the early warning module 6. When an abnormality is detected, an early warning signal is issued in a timely manner to remind the operator to take corresponding measures to avoid equipment failure or production accidents.

[0043] Optional, such as Figure 8 As shown, the control module 11 also includes a 24V power supply module 8; Control module 11 is electrically connected to 24V power supply module 8; The 24V power supply module 8 is used to power the early warning module 6, signal processing module 4, input / output module 5 and enable bit integrated circuit module 7 of the control module 11; The 24V power supply module 8 is located inside the controller housing 1.

[0044] The beneficial effects of the above optional embodiments are as follows: the 24V power supply module 8 can provide power to the warning module 6, signal processing module 4, input / output module 5 and enable bit integrated circuit module 7 to ensure the normal operation of the warning module 6, signal processing module 4, input / output module 5 and enable bit integrated circuit module 7.

[0045] Optional, such as Figures 1 to 7 As shown, it also includes an insulation device 2; The insulating device 2 is detachably connected to the controller housing 1. During operation, the insulating device 2 is used to shield the input / output module 5.

[0046] The insulating device 2 includes a folding plate 21 and a baffle 22; A baffle 22 is provided on each side of the folding plate 21, and the folding plate 21 is detachably connected to the controller housing 1; The baffle 22 and the folding plate 21 work together to block the input / output module 5.

[0047] In the above optional embodiments, it should be noted that both the folding plate 21 and the baffle 22 are made of insulating material, and the folding plate 21 is L-shaped. During operation, the folding plate 21 and the controller housing 1 are detachably connected by means of snap-fit ​​or screw connection. During operation, the folding plate 21 covers the upper surface and rear side of the input / output module 5, and the two baffles 22 cover the left and right sides of the input / output module 5 respectively. The front side and lower surface of the input / output module 5 are located inside the controller housing 1.

[0048] The advantages of the above optional embodiments are as follows: the setting of the folding plate 21 and the baffle 22 realizes the shielding of the input and output module 5 when the shredder is not working or not started, avoiding the safety of the operator due to leakage of the controller, and further increasing the safety of the shredder. When the shredder is started, neither the folding plate 21 nor the baffle 22 covers the input and output module 5, so as to avoid the insulation device 2 affecting the normal operation of the shredder.

[0049] Optional, such as Figures 1 to 7 As shown, the insulation device 2 also includes a fixing block 28 and a fastener 25; The fixing block 28 is disposed on the surface of the controller housing 1. One side of the fastener 25 is slidably connected to the fixing block 28. During operation, the other side of the fastener 25 is engaged with the folding plate 21.

[0050] The insulation device 2 also includes a slide rail 23 and a slide path 26; The slide 26 is disposed on the surface of the controller housing 1 and the slide 26 is disposed on the surface of the folding plate 21. The slide rail 23 and the slide 26 are slidably connected.

[0051] There are two fixing blocks 28, and the fastener 25 includes a connecting rod 251, two compression springs 252, a locking block 253 and two sliders 254; Two fixing blocks 28 are spaced apart on the controller housing 1, and each fixing block 28 is provided with a compression spring 252; Two sliders 254 are spaced apart on one side of the connecting rod 251, and a locking block 253 is provided on the other side of the connecting rod 251; Two sliders 254 are slidably inserted into two fixed blocks 28, and two compression springs 252 abut against the two sliders 254, respectively.

[0052] The folding plate 21 has a slot 24. When working, the card block 253 is inserted into the slot 24.

[0053] In the above optional embodiments, it should be noted that there are two slides 26 and two slide rails 23. The two slides 26 are parallel to each other, and the two slide rails 23 are parallel to each other. During operation, the two slide rails 23 are slidably connected to the two slides 26 in a one-to-one correspondence. One of the fixing blocks 28 is located between the two slides 26. The slides 26 are connected to the controller housing 1 by welding or screwing, and the slide rails 23 are connected to the folding plate 21 by welding or screwing.

[0054] The working principle of the insulation device 2 is as follows: When the controller is not working or not started, press the connecting rod 251, and then slide the folding plate 21 through the slide rail 23 and slide channel 26 to the position where the locking block 253 is located directly below the slot 24. Then release the connecting rod 251. Due to the action of the spring 252, the locking block 253 is locked in the slot 24, thus fixing the insulation device 2. When the shredder needs to work and the controller needs to be started, press the connecting rod 251, and then slide the folding plate 21 through the slide rail 23 and slide channel 26 until the folding plate 21 is away from the controller housing 1.

[0055] The advantages of the above optional embodiments are as follows: the reliable connection between the insulation device 2 and the controller housing 1 is achieved through the cooperative arrangement of the connecting rod 251, two compression springs 252, the locking block 253, two sliders 254, the slide rail 23 and the slide channel 26, thereby achieving reliable shielding of the input / output module 5 and ensuring the effectiveness of the insulation device 2.

[0056] Optional, such as Figure 1 As shown, the insulating device 2 also includes a handle 27, which is provided on the surface of the folding plate 21.

[0057] In the above optional embodiments, it should be noted that the handle 27 and the folding plate 21 are connected by means of screwing, welding or snap-fitting.

[0058] The advantages of the above optional embodiments are that the handle 27 increases the ease of operation of the insulation device 2.

[0059] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
