Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production and packaging, in particular to a real-time monitoring device for stem removal and cigarette equipment. Background Art

[0002] In cigarette production, if the stem picking intensity of the cigarette equipment's stem picking device is adjusted too much, it will cause tobacco waste, and if the stem picking intensity is adjusted too little, it will cause the cigarette to contain too many stems, affecting the smoking experience of the cigarette, and in serious cases, quality defects such as cigarette puncture may occur. During production, cigarette production personnel will take one minute of stem picking every two hours or so, weigh it, and determine whether it meets the process standards, and then adjust the stem picking device in time to ensure the quality of cigarettes. This method has a long time span for detecting the stem picking amount. If the measurement interval is shortened, it will increase the workload of production personnel.

[0003] In order to save manpower, the existing automatic stem receiving and weighing mechanism replaces the manual stem receiving and weighing scheme. When detection is required, the operator presses the detection button, and the automatic stem receiving mechanism will cut off the stem removal and collection device for one minute of measurement, and then feed back the measurement results to the operator. For example, Chinese patent CN202320652881.X discloses an online weighing device for tobacco stem removal from a cigarette machine, which realizes timed and quantitative measurement by setting a rotary cylinder, a receiving plate, a weighing sensor, etc. However, this method is essentially the same as the manual measurement method, the detection time span is large, and real-time continuous online monitoring is not possible.

[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Please refer to Figure 1 Some embodiments of the present application provide a real-time monitoring device for the amount of tobacco stems removed, which is arranged in a stem removing device in a cigarette making device and is used to monitor the weight of tobacco stems removed by the stem removing device, and includes a stem receiving mechanism 1 and a weighing mechanism 2; the stem receiving mechanism 1 is configured to receive tobacco stems and continuously remove tobacco stems in a preset manner; the weighing mechanism 2 is configured to weigh the weight of the stem receiving mechanism 1.

[0027] The stem receiving mechanism 1 receives the tobacco stems removed by the stem removing device and continuously removes the tobacco stems in a preset manner, so that the reading of the weighing mechanism 2 is related to the stem removal flow and weight of the stem removing device, and the flow of the stem removing device is calculated in combination with the preset method.

[0028] The structural design of the stem receiving mechanism 1 and the design of the preset mode are not limited. For example, it can be set as a ramp to allow the tobacco stems to slide down spontaneously.

[0029] In some embodiments, the stem receiving mechanism 1 includes a receiving surface for receiving the tobacco stems, and is configured to remove tobacco stems on a preset area of ​​the receiving surface at a preset speed. By using a receiving surface for receiving the tobacco stems and removing the tobacco stems at a preset speed, a more stable and consistent tobacco stem removal process can be provided, which helps to ensure that the reading of the weighing mechanism 2 is related to the stem removal flow of the stem removal device and accurately calculates the flow of the stem removal device. It also helps to reduce errors caused by uncertain factors, such as mechanical friction, unstable tobacco stem movement speed, etc., thereby improving the accuracy of monitoring.

[0030] In some embodiments, the stem receiving mechanism 1 includes a conveyor belt, which can receive the tobacco stems and continuously remove the tobacco stems at the end of the conveying direction. It is easy to implement, has a mature and simple structure, and can be applied to a wide range of working conditions by adjusting the belt speed.

[0031] The implementation method of the weighing mechanism 2 is not limited. The stem receiving mechanism 1 can be weighed. After the tobacco stems fall into the stem receiving mechanism 1 and before they are removed by the stem receiving mechanism 1, their weight is also measured by the weighing mechanism 2.

[0032] In some embodiments, the weighing mechanism 2 includes a cantilever beam gravity sensor. It is understood that the cantilever beam gravity sensor is a prior art, and has the advantages of good linearity, high precision, low height, small size, and output signal is not affected by the change of the force measurement point position.

[0033] In some embodiments, the weighing mechanism 2 is fixedly arranged by a first connecting member 3, and the first connecting member 3 is tightly connected to the stem removing device. The weighing mechanism 2 needs to be supported and stably installed, and the weighing mechanism 2 can be stably arranged by arranging the weighing mechanism 2 by the first connecting member 3.

[0034] Considering that the load-bearing end of the existing cantilever beam gravity sensor is usually point-shaped, for ease of installation, in some embodiments, the connecting mechanism 1 is connected to the weighing mechanism 2 through the second connecting member 4, and the second connecting member 4 includes a load-bearing plate 41 and a bracket 42. The load-bearing plate 41 is connected to the load-bearing end of the cantilever beam gravity sensor, and the bracket 42 connects the load-bearing plate 41 and the connecting mechanism 1. The weight of the connecting mechanism 1 first acts on the load-bearing plate 41 through the bracket 42, and then acts on the load-bearing end of the cantilever beam gravity sensor through the load-bearing plate 41, which is more stable.

[0035] Some embodiments of the present application also provide a cigarette making device, including a stem removing device configured to remove tobacco stems, and the real-time monitoring device for the amount of stems removed. It is understandable that the cigarette making device also has all the beneficial effects thereof because it includes the real-time monitoring device for the amount of stems removed.

[0036] In some embodiments, the stem removal device includes a stem collection device 100 and a suction duct 101 connected to the stem collection device 100 and providing negative pressure. The stem collection device 100 and the suction duct 101 can collect the stems measured by the monitoring device and the stems that have not fallen into the monitoring device.

[0037] In some embodiments, the stem receiving mechanism 1 is higher than the connection between the tobacco stem collecting device 100 and the air suction duct 101. The tobacco stems removed by the stem receiving mechanism 1 can be sucked into the air suction duct 101 to avoid being left in the stem receiving mechanism 1. At the same time, the influence of negative pressure air suction in the air suction duct 101 on the tobacco stems received by the stem receiving mechanism 1 can be reduced, and the tobacco stems can be prevented from being separated from the stem receiving mechanism 1 in a manner other than the preset manner, thereby reducing errors.

[0038] In some embodiments, the cigarette making device further comprises a drop buffer device configured to slow down the falling speed of the tobacco stems. The arrangement of the drop buffer device is not limited, as long as it can slow down the falling speed of the tobacco stems, such as by providing a blocking plate, providing a chute, or using gas to limit the falling, etc. The drop buffer device can reduce the error caused by the impact of the tobacco stems on the weighing mechanism, making the result more accurate.

[0039] Combine the following Figure 1 The specific embodiments of the present application are listed as follows: Figure 1 As shown, a specific embodiment of the real-time monitoring device for the amount of stems removed is arranged in a tobacco stem collecting device 100 of a stem removing device, and the tobacco stem collecting device 100 is bucket-shaped, and the lower end is connected to a suction duct 101 providing negative pressure. A cigarette making device including the stem removing device is a specific embodiment of a cigarette making device of the present application.

[0040] The specific embodiment of the real-time monitoring device for the amount of tobacco stems removed comprises: a stem receiving mechanism 1 and a weighing mechanism 2, wherein the stem receiving mechanism 1 comprises a conveyor belt, which is a conveyor belt built into the power mechanism and the control panel to prevent the tobacco stems from falling into the power mechanism and the control panel. The weighing mechanism 2 comprises two cantilever beam gravity sensors.

[0041] The weighing mechanism 2 is connected to the tobacco stem collecting device 100 of the stem removing device through the first connecting member 3. The first connecting member 3 and the tobacco stem collecting device 100 are welded. The weighing mechanism 2 and the first connecting member 3 are arranged on both sides of the conveyor belt, and space is left at both ends of the conveyor belt for the tobacco stems to fall.

[0042] The connecting mechanism 1 is connected to the weighing mechanism 2 through the second connecting member 4, and the second connecting member 4 includes a bracket 42 and a load-bearing plate 41. The bracket 42 is L-shaped, and the side of the bracket 42 is bolted to the side of the conveyor belt, and the bottom of the bracket 42 is bolted to the load-bearing plate 41. The load-bearing plate 41 is connected to the load-bearing end of the cantilever beam gravity sensor.

[0043] When the cigarette making machine is in operation, the stem removing device removes tobacco stems from the shredded tobacco, and the tobacco stems fall from the top of the shredded tobacco collecting device through the falling buffer mechanism into the tobacco stem collecting device 100, wherein part or all of the tobacco stems fall into the conveyor belt disposed inside the tobacco stem collecting device 100. When the tobacco stems are stably transported by the conveyor belt, the weighing mechanism 2 continuously weighs the conveyor belt, the tobacco stems thereon, and the second connecting member 4. Combining the weight data obtained by weighing with the information such as the conveying speed, area, length, and position of the conveyor belt, the amount of stems removed can be monitored by calculation.

[0044] The monitoring device of the present application is based on the weighing mechanism 2 designed for the tobacco stem collection mechanism of the tobacco stem removal device of the cigarette equipment, and the continuous weighing mechanism of the stem receiving device is placed on the weighing mechanism 2. Based on the original tobacco stem collection mechanism design, the rationality of the weighing and recycling method of the stem removal amount is effectively guaranteed. The setting method of the stem receiving device realizes the continuous recycling of tobacco stems during the stem removal measurement process. The weighing mechanism 2 can monitor the amount of tobacco stems transported by the conveyor belt in real time through signal transmission combined with formula calculation, and feed back information such as stem removal flow rate and stem removal weight to the operator, which is convenient for production.
