Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a cigarette box transparent paper pull-string conveyor device. Background Technology

[0002] Transparent paper is a key material in cigarette packaging, mainly used for sealing and anti-counterfeiting. During the packaging process, the transparent paper is pulled out from the reel, passes through multiple transition rollers, and is then tightly bonded to the cigarette box by heat sealing. During this process, the transparent paper often breaks or is missing. If this is not detected in time, it will affect the production process. In the existing technology, it is impossible to detect the breakage or missingness of the transparent paper during the pulling and conveying process. When the transparent paper roll is almost finished pulling, it is also impossible to remind the operator in time, which will affect the packaging process. In order to solve this technical problem, this utility model provides a cigarette box transparent paper pull-line conveying device. Utility Model Content

[0003] The purpose of this invention is to provide a cigarette box transparent paper pull-and-convey device to detect breakage and loss of the transparent paper during the pulling process. In addition, it can promptly remind the operator when the transparent paper roll is almost finished pulling.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A cigarette box transparent paper pull cord conveying device includes:

[0006] A pull-out reel for inserting a roll of transparent paper, the pull-out reel being mounted on a back plate;

[0007] A reel clamping mechanism is used to clamp a roll of transparent paper. The reel clamping mechanism is set on a back plate. A light emitter is set on the reel clamping mechanism.

[0027] Please see Figure 1 This utility model provides a cigarette box transparent paper pull-string conveying device, comprising:

[0028] A pull-out reel 5 is used to insert a roll of transparent paper, and the pull-out reel 5 is disposed on the back plate 1.

[0029] A reel clamping mechanism 8 is used to clamp the transparent paper roll to prevent it from bouncing when pulled out. The reel clamping mechanism 8 is mounted on a back plate 1, and a light emitter 10 is mounted on the reel clamping mechanism 8. A light receiver 13 is slidably mounted on the back plate 1, and the light receiver 13 and the light emitter 10 are located on the same vertical plane. The light receiver 13 and the light emitter 10 together form a photoelectric proximity switch. Preferably, there are two reel clamping mechanisms 8, located above and below the pull reel 5 respectively.

[0030] Specifically, the reel clamping mechanism 8 includes a base 81, a second spring 82, a clamping roller seat 83, and clamping rollers 84. The base 81 is fixedly mounted on the back plate 1, and the clamping roller seat 83 is slidably mounted on the back plate 1. The base 81 and the clamping roller seat 83 are connected by the second spring 82. The clamping rollers 84 are rotatably mounted on the clamping roller seat 83. There are two clamping rollers 84 on each clamping roller seat 83. When the transparent paper roll is inserted into the pull reel 5, the transparent paper roll is clamped by the elastic force of the second spring 82, thereby preventing the transparent paper roll from jumping when it is pulled out.

[0031] More specifically, a connecting rod 9 is provided on the clamping roller seat 83 located below, and a light emitter 10 is provided at the end of the connecting rod 9.

[0032] During use, as the transparent paper roll is continuously pulled out and consumed, the clamping roller seat 83 below the second spring 82 gradually rises under the elastic force. At the same time, the light emitter 10 gradually moves closer to the light receiver 13. When the light from the light emitter 10 shines on the light receiver 13, the light receiver 13 receives the signal and transmits it to the alarm device 6. The alarm device 6 then sounds an alarm to remind the operator to change the roll.

[0033] Wire pulling detection roller 3, reference Figure 2 As shown, the wire pulling detection roller 3 includes a roller body 32, a slider 33, a pressure sensor 35, and a support plate 34. A slot 1a is provided on the back plate 1, and the slider 33 is slidably disposed in the slot 1a. Preferably, the length of the slot 1a is 1-2 cm longer than the vertical length of the slider 33. The roller body 32 is disposed on the slider 33. Preferably, a roller 31 is also sleeved on the roller body 32, and the roller 31 can rotate freely on the roller body 32. The support plate 34 is disposed on the back plate 1 and located below the slot 1a. The support plate 34 is located on the rear side of the back plate 1, and a pressure sensor 35 is disposed on the support plate 34. A first spring 36 connects the support plate 34 and the slider 33. It should be noted that in the initial state, the slider 33 presses against the pressure sensor 35.

[0034] The controller 7 is electrically connected to the light receiver 13, the pressure sensor 35 and the alarm device 6 respectively, so as to issue an alarm based on the signal received by the light receiver 13 or the pressure sensor 35.

[0035] The device also includes an upper transition roller 2 and a lower transition roller 4, both of which are rotatably mounted on the back plate 1. The upper transition roller 2 is located above the wire pulling detection roller 3, and the lower transition roller 4 is located below the wire pulling detection roller 3.

[0036] To facilitate adjustment of the height of the light receiver 13, a guide rod 11 is provided on the back plate 1. The guide rod 11 is vertically arranged, and a magnetic ring 12 is inserted through the guide rod 11. The light receiver 13 is mounted on the magnetic ring 12 and can be clamped onto the magnetic ring 12 by a fastening bracket. Preferably, the guide rod 11 is marked with a scale. By adjusting the height of the light receiver 13, alarms can be triggered as needed to detect different levels of consumption of the transparent paper roll.

[0037] refer to Figure 3 As shown, in some implementations, the controller 7 includes an amplifier 71 and a PLC control module 72. The PLC control module 72 can be an S7-200 type PLC. The amplifier 71, the PLC control module 72 and the alarm device 6 are electrically connected in sequence. The light receiver 13 and the pressure sensor 35 are electrically connected to the amplifier 71 respectively, and the received signal is amplified by the amplifier 71.

[0038] The working principle of this utility model is as follows: the transparent paper roll is placed on the pull reel 5 and clamped by the reel clamping mechanism 8 to prevent it from jumping. As the transparent paper is continuously pulled out and consumed, the diameter of the transparent paper roll on the pull reel 5 continuously decreases. Due to the rebound force of the second spring 82 in the reel clamping mechanism 8, the clamping roller 84 synchronously adheres to the transparent paper roll, and the clamping roller seat 83 located below continuously moves upward. When the light emitted by the light emitter 10 on one side of the clamping roller seat 83 shines on the light receiver 13, the alarm device 6 is activated through the PLC control module 72 to remind people to change the roll.

[0039] During the conveying process of the transparent paper roll, the transparent paper provides an upward pulling force to the pull detection roller 3, which causes the slider 33 to pull away from the pressure sensor 35 or reduce the pressure value of the pressure sensor 35. When the transparent paper is broken or missing, the pull detection roller 3 loses the upward pulling force. At this time, the gravity of the slider 33 acts on the pressure sensor 35, causing the pressure sensor 35 value to increase. This, in turn, activates the alarm device 6 through the PLC control module 72, thus alerting people that the transparent paper has broken or is missing.

[0040] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that those skilled in the art can devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides modifications and improvements to the components or layout, other uses will be apparent to those skilled in the art.
