Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment, and more specifically, to a device for cleaning obstructions from phototubes in a slicer. Background Technology

[0002] In filament production lines, the photocells used for through-beam scanning are frequently obstructed by dust, tobacco flakes, and other debris, causing erroneous signal transmission and leading to equipment malfunctions or shutdowns. For example, the photocells used for identifying tobacco bale volume and the discharge photocells in slicing machines are prone to obstruction due to the low moisture content and high dust levels of the material before loosening and rehydration during the slicing process. The operation of slicing machines is relatively dangerous, and the photocells, located inside the machine, are difficult to clean. If obstruction occurs, manual cleaning is usually required, which can cause mechanical injury to workers. Using a dedicated cleaning device can promptly address obstruction. Therefore, designing a photocell cleaning device that reduces cleaning risks and labor intensity is of great importance. Utility Model Content

[0029] To enable those skilled in the art to better understand the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and implementation methods.

[0030] To address the problem of high risk and low efficiency in manual cleaning of the photoelectric tubes of tobacco slicing machines when they are obstructed by dust, tobacco leaves, and debris, this invention provides a device for cleaning obstructions from the photoelectric tubes of slicing machines. This device solves the problem of high risk and low efficiency in manual cleaning of the photoelectric tubes of slicing machines on existing tobacco processing production lines when they are obstructed by dust, tobacco leaves, and debris, improving cleaning efficiency, increasing safety, and reducing labor costs.

[0031] like Figures 1-3As shown, a device for cleaning obstructions from a phototube in a slicer includes: a mounting box 6, a brush 2, and a driving device 1. The mounting box 6 is divided into a left chamber and a right chamber. The driving device 1 is located in the left chamber, and the phototube 3 is located at the bottom of the right chamber. A cleaning box 4 is located on the upper layer of the right chamber, positioned above the phototube 3. The cleaning box 4 has an open structure, with a cleaning groove 41 and a dust outlet 42. A through hole (not shown) is provided in the cleaning groove 41, through which the laser emitted by the phototube 3 passes. The cleaning groove 41 is connected to the dust outlet 42. The driving device 1 is driven by the brush 2, which is slidably disposed on the upper surface of the cleaning groove 41. When the driving device operates, it drives the brush to sweep back and forth along the upper surface of the cleaning groove, causing foreign objects falling into the cleaning groove to be discharged from the dust outlet.

[0032] Specifically, the phototube is housed inside the mounting box, and a cleaning box is positioned above it. The cleaning box has an open structure with a cleaning groove and a dust outlet. A brush is slidably mounted within the cleaning groove. A driving device drives the brush to sweep back and forth along the upper surface of the cleaning groove, allowing dust and other foreign objects to be discharged from the dust outlet. Note that the dust outlet can be installed facing downwards. This double-layer design of the cleaning device inherently prevents a significant amount of dust and smoke from falling onto the laser beam path. In most cases, a small amount of dust will fall into the cleaning layer through the conical hole, reducing cleaning workload, improving cleaning efficiency, and increasing safety.

[0033] Furthermore, the cleaning groove 41 has a fan-shaped structure, and the brush is arranged along the fan-shaped axis so that the brush swings back and forth around a fan-shaped cleaning area at one end when the drive device is running.

[0034] Furthermore, the drive device is a servo motor.

[0035] The device further includes a purging device; the purging device is disposed inside the mounting box and is used to purge the cleaning groove to blow away foreign objects.

[0036] The device also includes a PLC controller (not shown in the figure); the PLC controller is connected to the servo motor and the blowing device respectively, and the PLC controller controls the blowing device to blow away foreign objects when there are still foreign objects blocking the laser path of the phototube after the brush cleaning.

[0037] Furthermore, the purging device includes: a purging air pipe 5 and a solenoid valve (not shown in the figure); the purging air pipe is connected to an external compressed air source, and the solenoid valve is installed on the purging air pipe; the PLC controller is signal-connected to the solenoid valve and is used to control the opening and closing of the solenoid valve, so that the purging air pipe releases or shuts off the compressed air.

[0038] In practical applications, when the phototube of the slicing machine is working, the material periodically interrupts the laser signal. A judgment time (20 seconds) is set according to this pattern. If the laser signal is blocked for longer than the judgment time, it is determined that there is accumulated dust in the cleaning layer or that the top layer is blocked by smoke sheets, and the device initiates a cleaning action. If, after cleaning with a brush, foreign objects still obstruct the laser path, the purge air pipe inside the mounting box will release compressed air to blow away the obstruction. The cleaning action can continue in a loop until the laser signal is reconnected.

[0039] The device further includes: a control panel (not shown in the figure); the control panel is signal-connected to the PLC controller, and the control panel is provided with a servo control button and a purge control button; when the servo control button or the purge control button is pressed, the PLC controller controls the corresponding servo or the purge device to operate to perform cleaning operations.

[0040] In practical applications, this cleaning device has both manual and automatic operating modes. In automatic mode, the PLC controller compares the normal material passage time to determine if the photoelectric tube signal is blocked by a foreign object. If the signal is blocked for a period exceeding a certain range of the normal material passage time, it is considered an obstruction. In this case, a cleaning action is initiated. In manual mode, the operator controls the servo motor and blowing device via the control panel.

[0041] Furthermore, the top layer of the mounting box 6 is provided with a tapered through hole 7, which is located above the cleaning groove. The apex of the tapered through hole 7 is located on the upper surface of the top layer, and the bottom angle of the tapered through hole 7 is located on the inner side of the top layer. The tapered through hole 7 corresponds to the through hole, so that the laser of the phototube passes through the tapered through hole and the through hole to form a laser path.

[0042] In practical applications, the tapered through-hole can block most obstructions, reducing the amount of cleaning work, and the tapered hole prevents dust from accumulating on the hole wall.

[0043] Furthermore, the brush has a double-layer structure.

[0044] Furthermore, the ash outlet is located on the side of the cleaning box, and the air outlet of the blowing air pipe is positioned opposite to the ash outlet.

[0045] As can be seen, this utility model provides a device for cleaning obstructions from phototubes in slicing machines. The phototube is mounted in a mounting box, and a cleaning box is placed above the phototube. A brush and a driving device are installed inside the mounting box. The driving device drives the brush to clean the cleaning grooves in the cleaning box back and forth. This solves the problem of high danger and low efficiency when manual cleaning is required when the through-beam phototubes of slicing machines in existing silk production lines are blocked by dust, smoke, and debris. It can improve cleaning efficiency, increase safety, and reduce labor costs.

[0046] The structure, features and effects of this utility model have been described in detail above with reference to the embodiments shown in the figures. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the figures. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and figures, shall be within the protection scope of this utility model.
