Description

Technical Field

[0001] The present application relates to the technical field of cigarette stack loose disc detection equipment, and in particular to a mechanism for cigarette stack loose disc detection. Background Art

[0002] Loose pallets refer to the phenomenon that during the storage or transportation process, the stability of the stacking of goods (such as tobacco products) that were originally tightly stacked is destroyed due to various reasons (such as vibration, pressure, humidity changes, etc.), and the goods become loose or scattered. In the tobacco industry, the loose pallet condition of cigarette stacks is of great significance to product quality, storage safety and transportation efficiency. Therefore, the loose pallet detection of cigarette stacks is an important link to ensure the quality and safety of tobacco products. The existing Chinese patent (application number: CN202222880780.6) discloses a device for detecting the appearance uniformity of a whole stack of products, including a main body mechanism, a supporting mechanism, an adjusting mechanism and a heat dissipation mechanism, wherein the supporting mechanism is located on the lower side of the main body mechanism, the adjusting mechanism is located at the lower end of the main body mechanism, and the heat dissipation mechanism is located inside the main body mechanism. The main body mechanism includes a mounting support plate, a mounting support rod, a uniformity detector and a uniformity detection end, and the mounting support rod is fixedly mounted on the upper end of the mounting support plate. The device for detecting the appearance neatness of a whole stack of products improves the lifting and adjusting capabilities of the device for detecting the appearance neatness of a whole stack of products by improving and installing a supporting mechanism and an adjusting mechanism. During actual use, the height and direction of the device for detecting the appearance neatness of a whole stack of products can be adjusted according to actual conditions, thereby improving the working effect of the device for detecting the appearance neatness of a whole stack of products.

[0003] During use of the above device, the electric push rod is controlled to extend and retract, the whole stack product appearance neatness detection device is adjusted to a suitable height, and then the whole stack product appearance neatness detection device is adjusted to a suitable position through the universal wheel to perform three-plate detection. Although it can also perform detection, due to the limited extension and retraction stroke of the electric telescopic rod, it may not be possible to perform a comprehensive detection for some relatively high goods.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] In response to the above-mentioned problems, an embodiment of the present application provides a mechanism for detecting cigarette stack loose discs, which can further adjust the height of the acoustic wave detector, thereby improving the accuracy of the height adjustment.

[0027] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0028] See also Figure 1-2 The mechanism for detecting the loose disc of cigarette stacks comprises a mounting base 1; a lifting assembly 2 for adjusting the detection height is arranged in the mounting base 1, the lifting assembly 2 comprises a threaded rotating rod 201 rotatably connected to the mounting base 1, a threaded barrel 202 is threadedly connected to the threaded rotating rod 201, a servo motor 203 for driving the threaded rotating rod 201 to rotate is connected to the bottom of the mounting base 1, a sound wave detector 204 for detecting which is synchronously adjusted with the threaded barrel 202 is arranged on one side of the threaded barrel 202, and an adjusting assembly 8 for further raising the detection height is also arranged on the lifting assembly 2.

[0029] There are two threaded rods 201 and two threaded barrels 202 symmetrically arranged on the mounting base 1 , one of the threaded rods 201 is connected to the servo motor 203 , a synchronous wheel 5 is connected to the threaded rod 201 , and a synchronous belt 6 is connected between the two synchronous wheels 5 .

[0030] The adjustment component 8 includes a winding roller 801 connected to one side of the mounting base 1, a lap pulley 803 is connected to the top of the threaded cylinder 202, a connecting rope 802 is wound around the winding roller 801, the connecting rope 802 is lapped on the lap pulley 803, one end of the connecting rope 802 away from the winding roller 801 is connected to the acoustic wave detector 204, and the ends of the two connecting ropes 802 are symmetrically connected to the acoustic wave detector 204.

[0031] During operation, the acoustic wave detector 204 can perform multiple heights of loose disc detection by cooperating with the lifting component 2 and the adjusting component 8, driving the servo motor 203 to drive the threaded rotating rod 201 to rotate. While the threaded rotating rod 201 rotates, the threaded barrel 202 can be driven to adjust the height synchronously, and then the overlap pulley 803 is used to adjust the height, and then the acoustic wave detector 204 can be adjusted in height synchronously to adapt to cigarette stacks of different heights, and the connecting rope 802 can be driven to stretch or shorten by rotating the winding roller 801. In this process, the height of the acoustic wave detector 204 can be further adjusted, thereby improving the accuracy of the height adjustment.

[0032] The sound wave detector 204 sends a sound wave signal to the cigarette pile and determines the internal structure and the scattered disc condition of the cigarette pile by analyzing the reflected sound wave signal. This is a prior art and should be known to those skilled in the art, so no further explanation is given here.

[0033] To facilitate the rotation of the winding roller 801, a handle can be connected to one side of the winding roller 801 to facilitate the rotation of the winding roller 801. To facilitate the synchronous rotation of the two winding rollers 801, a circle counter can be connected to one side of the winding roller 801 so that the two winding rollers 801 rotate the same number of circles. To facilitate the adjustment of the detection range of the acoustic wave detector 204, universal wheels are connected to the four corners of the bottom of the mounting base 1, and locking buckles are provided on the universal wheels.

[0034] To ensure the stability of the acoustic wave detector 204 during the height adjustment process, the number of the threaded rotating rod 201 and the threaded barrel 202 are both two. The threaded rotating rod 201 is connected to a synchronous wheel 5, and a synchronous belt 6 is connected between the two synchronous wheels 5. The two threaded barrels 202 are arranged so that the acoustic wave detector 204 can be subjected to pulling forces in two directions during the height adjustment process, further improving the stability of the acoustic wave detector 204 during the height adjustment process. The synchronous wheel 5 and the synchronous belt 6 can be used in combination so that the two threaded rotating rods 201 only need one servo motor 203 to drive them, thereby reducing the manufacturing cost of the device.

[0035] In some embodiments, see Figure 1 and 3 The mounting base 1 is connected to a mounting plate 3, the threaded tube 202 is connected to a guide rod 4, the guide rod 4 is vertically slidably connected to the mounting plate 3, and the mounting plate 3 is provided with a slide groove for the guide rod 4 to slide.

[0036] During operation, the height adjustment of the threaded barrel 202 is limited and guided by the cooperation of the mounting plate 3 and the guide rod 4, so that the threaded barrel 202 will not rotate with the rotation of the threaded rotating rod 201.

[0037] In some embodiments, see Figure 1 and 4 The mechanism for detecting the loose disc of cigarette stacks also includes a locking assembly 7 for limiting the rotation of the winding roller 801. A connecting block is connected to one side of the mounting base 1, and the winding roller 801 is connected to the connecting block. The locking assembly 7 includes a fixed block 701, a limiting member 702, a connecting rod 703, a compression spring 704, and a transmission disk 705 connected to the winding roller 801. The connecting block is connected to the fixed block 701, and the fixing block 701 is slidably connected to the connecting rod 703. One end of the connecting rod 703 is connected to the limiting member 702 for limiting the transmission disk 705. A compression spring 704 is sleeved on the connecting rod 703, and one end of the compression spring 704 is connected to the fixed block 701, and the other end is connected to the limiting member 702.

[0038] During operation, in order to facilitate the improvement of the stability of the winding roller 801 during the rotation process, before rotating the winding roller 801, pull the connecting rod 703 so that one side of the limiting member 702 no longer conflicts with the transmission disk 705. At this time, the winding roller 801 can be rotated. After the rotation is completed, release the connecting rod 703 so that the limiting member 702 is clamped on the transmission disk 705 by the elastic force of the compression spring 704 to limit the transmission disk 705 and the winding roller 801. After the winding roller 801 is limited, the connecting rope 802 cannot be stretched, and the position of the acoustic wave detector 204 can be located at this time.

[0039] In some embodiments, a side of the position limiting member 702 opposite to the transmission disk 705 is provided with an arcuate slope matching the arcuate surface of the transmission disk 705, and an anti-skid pad is connected to the arcuate slope, and the anti-skid pad has anti-skid patterns integrally formed thereon.

[0040] During operation, the anti-skid pad can increase the friction between the arc-shaped inclined surface of the limiter 702 and the transmission plate 705, making the position of the acoustic wave detector 204 more stable.

[0041] Working process of this application:

[0042] When it is necessary to detect cigarette stacks of different heights: the lifting component 2 and the adjusting component 8 are used in conjunction to enable the acoustic wave detector 204 to perform loose disc detection at multiple heights, and the servo motor 203 is driven to drive the threaded rotating rod 201 to rotate. While the threaded rotating rod 201 rotates, the threaded cylinder 202 can be driven to adjust the height synchronously, and then the overlap pulley 803 is used to adjust the height, and then the acoustic wave detector 204 can be adjusted in height synchronously to adapt to cigarette stacks of different heights, and the connecting rope 802 can be driven to stretch or shorten by rotating the winding roller 801. In this process, the height of the acoustic wave detector 204 can be further adjusted, thereby improving the accuracy of the height adjustment.

[0043] Before rotating the winding roller 801, pull the connecting rod 703 so that one side of the limit piece 702 no longer conflicts with the transmission disk 705. At this time, the winding roller 801 can be rotated. After the rotation is completed, release the connecting rod 703 so that the limit piece 702 is clamped on the transmission disk 705 by the elastic force of the compression spring 704 to limit the transmission disk 705 and the winding roller 801. After the winding roller 801 is limited, the connecting rope 802 cannot be stretched, and the position of the acoustic wave detector 204 can be located at this time.
