Technical Field

[0001] The utility model relates to the technical field of cigarette processing equipment, in particular to a device for detecting the bottom edge opening of a small box of a packaging machine. Background Art

[0002] Currently, on the cigarette packaging production line, the unit arranges and sorts the cigarettes in a fixed quantity, wraps them with lining paper and label paper, and affixes seals to form small packs. The folded wings and bottom of the small pack wrapping paper are sprayed with hot melt adhesive. After passing through the cigarette pack drying and output channel, the small packs are formed. The packaged small packs pass through the cigarette pack output wheel and conveyor channel and enter the auxiliary machine for small packs to be wrapped with transparent paper, packed into strips, and sealed with transparent paper, completing the strip packaging process.

[0003] However, during the production process, cigarette packs with broken or partially broken bottoms often enter the auxiliary machines due to adhesive deposits on the hot melt adhesive nozzle, dirty detection surfaces, or long downtime. This poses a quality risk of small boxes with broken bottoms entering the market. Therefore, a device for detecting broken bottoms in packaging machines is urgently needed to prevent these problems.

[0040] The following describes in detail embodiments of the present invention. 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 intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] like Figures 1 to 7 As shown, the present invention provides a device for detecting the bottom edge of a small box of a packaging machine, comprising a fixed housing 100, a detection plate 200, a proximity switch 300, and a fixing bracket 400. The fixed housing 100 is mounted on the guide rail 10 of the auxiliary machine; the detection plate 200 is made of iron and is rotatably mounted on the fixed housing 100. The top upper surface of the detection plate 200 is lower than the bottom lower surface of the small box, and a baffle 210 is provided at the bottom of the detection plate 200; the proximity switch 300 is mounted on the fixed housing 100 and is electrically connected to the control module of the auxiliary machine; the fixing bracket 400 is made of iron and is mounted on the fixed housing 100. The fixing bracket 400 is provided with a magnet 410, which is used to make the fixing bracket 400 magnetic. The fixing bracket 400 is used to magnetically attract the top of the detection plate 200 so that the baffle 210 is aligned with the proximity switch 300.

[0042] The present invention provides a device for detecting the open edge at the bottom of a small box for a packaging machine. When in use, the auxiliary machine conveys the small box of cigarette packs. When the small box with the open edge at the bottom moves to the top of the detection plate 200, the open edge at the bottom of the small box will drive the detection plate 200 to rotate relative to the fixed shell 100, so that the baffle 210 is away from the proximity switch 300. The proximity switch 300 transmits a signal to the control module of the auxiliary machine, and the auxiliary machine generates a fault and shuts down, indicating that there is an open edge at the bottom of the small box. After the fault is handled, the detection plate 200 is manually reset, and the fixing frame 400 magnetically attracts the top of the detection plate 200 to make the baffle 210 aligned with the proximity switch 300, and the auxiliary machine can then start normally.

[0043] In some embodiments, the fixed shell 100 includes a front shell 110, a rear shell 120, a right shell 130 and an installation shell 140; the front shell 110, the right shell 130 and the rear shell 120 are connected in sequence, and the two ends of the detection board 200 are rotatably connected to the front shell 110 and the rear shell 120 respectively, the fixing frame 400 is set on the right shell 130, and the proximity switch 300 is set on the rear shell 120; the installation shell 140 is set on the top of the rear shell 120, and the installation shell 140 is installed on the guide rail 10.

[0044] In some specific embodiments, a rotating shaft 220 is installed in the middle of the detection plate 200, and a rotating hole 221 is formed in the rotating shaft 220 along the axial direction; the front housing 110 is provided with a first screw hole 111, and the first screw 112 is threadedly connected to the first screw hole 111, and the first screw 112 extends into the rotating hole 221; the rear housing 120 is provided with a second screw hole 121 aligned with the first screw hole 111, and the second screw 122 is threadedly connected to the second screw hole 121, and the second screw 122 extends into the rotating hole 221. When the bottom opening of the small box drives the detection plate 200 to rotate relative to the fixed housing 100, the rotating shaft 220 rotates relative to the first screw 112 and the second rotating hole 221 through the rotating hole 221, thereby achieving rotation of the two ends of the detection plate 200 relative to the front housing 110 and the rear housing 120.

[0045] A third screw hole 222 is radially opened in the middle part of the rotating shaft 220, and a through hole 230 is opened in the middle part of the detection plate 200. The third screw 223 passes through the through hole 230 and is threadedly connected to the third screw hole 222. The third screw 223 realizes a detachable connection between the rotating shaft 220 and the middle part of the detection plate 200.

[0046] In some embodiments, the right housing 130 defines a fourth screw hole 131, into which a bolt 132 is threadedly connected. The fixing bracket 400 defines a strip-shaped hole 420, through which the bolt 132 passes and is threadedly connected to a nut 133. The magnet 410 is sandwiched between the fixing bracket 400 and the nut 133. The bolt 132 and the nut 133 provide a detachable connection between the fixing bracket 400 and the right housing 130. Furthermore, the strip-shaped hole 420 in the fixing bracket 400 facilitates positional adjustment of the fixing bracket 400.

[0047] In some embodiments, the mounting housing 140 includes an upper housing 141 and a lower housing 142. The upper housing 141 defines a fifth screw hole 143, into which a fourth screw 144 is threadedly connected, and the fourth screw 144 is threadedly connected to the top of the guide rail 10. The lower housing 142 defines a sixth screw hole 145, into which a fifth screw 146 is threadedly connected, and the fifth screw 146 is threadedly connected to the bottom of the guide rail 10. This structure achieves a detachable connection between the mounting housing 140 and the guide rail 10, facilitating assembly and disassembly of the mounting housing 140.

[0048] In some embodiments, the top upper surface of the detection plate 200 is 0.5 mm lower than the bottom lower surface of the small box, ensuring that when a small box with an open edge at the bottom appears, the open edge at the bottom of the small box drives the detection plate 200 to rotate relative to the fixed shell 100. When there is no open edge at the bottom of the small box, the small box does not contact the detection plate 200, and the small box with an open edge at the bottom can be accurately detected.

[0049] The device for detecting the open edges at the bottom of a small box for a packaging machine provided by the utility model can effectively detect cigarette packs with quality defects such as open edges or incomplete open edges at the bottom of the small box through the cooperation of the detection plate 200 and the proximity switch 300, thereby avoiding the defective cigarette packs from flowing into the next process to the greatest extent and providing strong support for high-quality production.

[0050] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
