Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco production equipment, and in particular relates to a rake roller detection device for a bottom belt side chain conveying type cigarette storage cabinet. Background Art

[0002] In the tobacco-making workshop of a cigarette factory, the bottom-belt side-chain conveyor-type tobacco storage cabinet is a key equipment. It is mainly used to age, store and balance process parameters of tobacco leaves, tobacco shreds, tobacco stems, stem shreds and other tobacco materials, buffer the production of upstream and downstream equipment in preparation for subsequent processing steps, and at the same time adjust production time, change production varieties and improve equipment operation efficiency.

[0003] The discharge part of the storage cabinet is mainly composed of the bottom belt and the rake roller, which work together to achieve smooth material transportation. However, in the actual operation process, the gear transmission chain driven by the reducer may be disconnected or dropped during operation, which will cause the rake roller to be unable to loosen the material out of the cabinet in real time. At this time, the air switch of the reduction motor will not trip and cause an alarm, so it is difficult for the operator to find and deal with this problem in time. As the material continues to move toward the cabinet head, the rake roller may get stuck in the material. If the bottom belt motor continues to run, the bottom belt crossbeam may be deformed and damaged, and the material may be blocked at the storage cabinet outlet. The emergence of this problem will not only affect production efficiency, but may also cause equipment damage and material waste.

[0004] In addition, the technical defects of the existing storage cabinet discharging system have resulted in the current monitoring and alarm system lacking effective real-time monitoring means for the operation status of the rake roller, and being unable to promptly detect and solve problems such as the rake roller getting stuck or blocking. This has increased uncertainty and risk in the production process, and reduced production efficiency and equipment life.

[0005] Therefore, in view of the technical problems existing in the discharging system of the bottom belt side chain conveyor type cigarette storage cabinet, it is urgent to design an effective real-time monitoring and alarm system to realize real-time monitoring of the operating status of the rake roller and fault warning. Utility Model Content

[0006] Aiming at the technical defects of the existing bottom belt side chain conveyor type cigarette storage cabinet discharging system in the background technology, which leads to the inability to timely discover and solve the problems of the rake roller stuck or blocked, the utility model provides a rake roller detection device based on the existing bottom belt side chain conveyor type cigarette storage cabinet.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rake roller detection device for a bottom belt side chain conveyor type cigarette storage cabinet, comprising a bracket and a non-metallic turntable, the bracket is mounted on the storage cabinet frame, an electromagnetic proximity switch is mounted on the bracket, the non-metallic turntable is mounted on the rake roller shaft, an iron sheet is eccentrically arranged on the non-metallic turntable, the electromagnetic proximity switch marks the running state of the rake roller in a pulse counting manner by sensing the iron sheet, which is used to determine the current material discharging working state, and the signal output end of the electromagnetic proximity switch forms a pulse signal interlocking control with the cabinet conveying bottom belt motor frequency converter through the PLC controller, and adjusts the material flow of the cabinet out of the cabinet, so as to ensure that the rake roller runs at a constant speed. That is, the rake roller is set to rotate one circle in 3 seconds in the PLC controller, and the delay relay is set at the same time. If no pulse signal is detected within 3 seconds, the PLC controller will alarm and stop through the cabinet conveying bottom belt motor frequency converter.

[0008] As a further supplementary explanation of the above technical solution, a circular groove is provided on the non-metallic turntable, the iron sheet is embedded in the circular groove, and its end surface is flush with the non-metallic turntable.

[0009] As a further supplement to the above technical solution, a through hole connected to the circular groove is provided on the non-metallic turntable, and a first bolt column is provided on the iron sheet. The first bolt column passes through the through hole and uses a gasket to cooperate with a first nut to fix the iron sheet in the circular groove.

[0010] As a further explanation and limitation of the above technical solution, the bracket includes a vertical plate and a horizontal plate, and the two are vertically connected to form an L-shaped structure. A mounting hole is provided on the vertical plate, and the electromagnetic proximity switch is installed in the mounting hole. A strip slot hole is provided on the horizontal plate, and the mounting bolts pass through the strip slot hole to fix the bracket to the cabinet frame.

[0011] As a further supplement to the above technical solution, a circular hole is arranged at the center of the non-metallic turntable, and a second bolt column is arranged at the end of the rake roller shaft.

[0024] The support includes: a vertical plate 101 and a horizontal plate 102 . DETAILED DESCRIPTION

[0025] In order to further illustrate the technical solution of the utility model, the following Figures 1 to 4 ,According to the on-site transformation process, we further illustrate the utility model through three embodiments. Embodiment 1

[0026] As attached Figure 1 , 2 As shown in Figure 4, a rake roller detection device for a bottom belt side chain conveyor type cigarette storage cabinet is mainly composed of a bracket 1 and a non-metallic turntable 3. The design of the bracket 1 is unique. It is formed by vertically connecting a vertical plate 101 and a horizontal plate 102 to form a solid L-shaped structure. A mounting hole 11 is cleverly set on the vertical plate 101, and the electromagnetic proximity switch 2 is firmly installed in this hole. A strip slot 12 is set on the horizontal plate 102, and the mounting bolt 13 can flexibly pass through this slot to firmly fix the bracket 1 on the cabinet frame 19. Such a design not only ensures the stability of the bracket, but also facilitates installation and adjustment. The non-metallic turntable 3 is another core component of the device. It is installed on the rake roller shaft 18 and rotates with the rotation of the rake roller. On the non-metallic turntable 3, a piece of iron sheet 4 is eccentrically set. When the turntable rotates, the iron sheet 4 will periodically approach and move away from the electromagnetic proximity switch 2. The electromagnetic proximity switch 2 can sense the approach of the iron sheet 4 and mark the running state of the rake roller in the form of pulse counting. In this way, we can accurately determine the working state of the current discharging.

[0027] When the bottom belt side chain conveyor type cigarette storage cabinet is working normally, as the material moves forward, the rake roller rotates at a certain speed, driving the non-metallic turntable 3 to rotate. When the iron sheet 4 embedded in the non-metallic turntable 3 is close to the proximity switch, the proximity switch is turned on, and the PLC circuit receives the signal within the delay relay time and continues to work. Otherwise, it will automatically stop and send an alarm message: the rake roller is blocked. In this way, we can accurately control the material flow rate out of the storage cabinet and ensure that the rake roller runs at a constant speed.

[0028] In this embodiment, the non-metallic turntable 3 is preferably made of nylon. Nylon has excellent mechanical properties and wear resistance, which can ensure the long-term use of the turntable. At the same time, the nylon material has little interference with the electromagnetic signal, which can ensure the accurate sensing of the electromagnetic proximity switch 2 to the iron sheet 4. Of course, those skilled in the art can also choose other suitable materials to make the non-metallic turntable 3 according to actual needs. As long as these materials can interfere with the electromagnetic proximity switch to generate the sensing signal, the creative ideas and design ideas of the utility model can be realized. Embodiment 2

[0029] As attached Figure 2As shown, we set a circular groove 6 on the non-metallic turntable 3 so that the iron sheet 4 can be embedded therein, and its end face is kept flush with the non-metallic turntable 3. This design not only improves the overall aesthetics of the turntable, but more importantly, enhances the structural stability of the turntable. The close combination of the iron sheet 4 and the non-metallic turntable 3 makes the turntable more secure during use, reducing the safety risks caused by loose or falling parts.

[0030] In this embodiment, we further set a through hole 5 connected to the circular groove 6 on the non-metallic turntable 3. This design allows the first bolt column 7 on the iron sheet 4 to pass through the through hole 5, and then the iron sheet 4 is firmly fixed in the circular groove 6 by the gasket 8 and the first nut 9. This fixing method is not only simple and easy, but also has a very reliable fixing effect. Through the cooperation of the bolts and nuts, it can be ensured that the iron sheet 4 will not shift or fall off when the turntable rotates or is subjected to external force, thereby further enhancing the structural strength and stability of the turntable.

[0031] This fixing method also has good maintainability. When the iron sheet 4 needs to be replaced or repaired, the iron sheet 4 can be easily taken out from the circular groove 6 by simply loosening the first nut 9. This greatly reduces maintenance costs and time and improves work efficiency. Embodiment 3

[0032] As attached Figures 2 to 4 As shown, according to the actual installation environment and requirements, we provide the following two flexible installation methods to install the non-metallic turntable 3 to ensure its stable connection with the rake roller shaft 18. The specific installation methods are as follows:

[0033] (I) Bolt-fixed installation: First, a circular hole 10 is pre-opened at the center of the non-metallic turntable 3. The size of the circular hole 10 must match the diameter of the rake roller shaft 18 to ensure that the non-metallic turntable 3 can be smoothly mounted on the rake roller shaft 18. Next, a second bolt column 16 is set at the corresponding end of the rake roller shaft 18. The diameter of the bolt column should be smaller than the diameter of the central circular hole 10 of the non-metallic turntable 3 so that it can pass through the circular hole 10. Then, the non-metallic turntable 3 is mounted on the rake roller shaft 18 through the circular hole 10, so that the second bolt column 16 passes through the circular hole 10. At this time, a certain degree of coaxiality should be maintained between the non-metallic turntable 3 and the rake roller shaft 18 to ensure the stability and reliability of the installation. Finally, the non-metallic turntable 3 is fixed to the rake roller shaft 18 using the second nut 17. During the specific operation, the second nut 17 is screwed onto the second bolt column 16, and the non-metallic turntable 3 is firmly fixed to the rake roller shaft 18 by the locking force of the nut. This installation method is simple and fast, and is suitable for occasions where the installation accuracy is not required to be high.

[0034] (ii) Sleeve fastening installation: First, it is also necessary to set a sleeve 14 at the center position of the non-metallic turntable 3. The inner diameter of the sleeve 14 should be slightly larger than the diameter of the rake roller shaft 18 so that it can be easily sleeved on the rake roller shaft 18. Then, fastening bolts 15 are set on the outer wall of the sleeve 14. The number and position of these bolts should be designed according to actual needs to ensure that the connection between the non-metallic turntable 3 and the rake roller shaft 18 is firm and reliable. Next, the non-metallic turntable 3 is sleeved on the end of the rake roller shaft 18 through the sleeve 14. During the sleeve installation process, care should be taken to maintain the coaxiality of the non-metallic turntable 3 and the rake roller shaft 18 to avoid deflection or shaking. Finally, use a tool to tighten the fastening bolts 15 so that the non-metallic turntable 3 is firmly connected to the rake roller shaft 18 through the sleeve 14. This installation method is suitable for occasions where high installation accuracy is required or high load requirements are required for the non-metallic turntable 3.

[0035] Through the above two installation methods, we can choose the appropriate installation method according to the actual installation environment and needs to achieve a stable connection between the non-metallic turntable 3 and the rake roller shaft 18. Whether it is a bolt-fixed installation or a sleeve-fastened installation, it can ensure that the non-metallic turntable 3 maintains a stable operating state during the working process, thereby improving the overall performance and reliability of the equipment.

[0036] The above shows and describes the main features and advantages of the utility model. For those skilled in the art, it is obvious that the specific implementation of the utility model is not limited to the details of the above exemplary embodiments, and the creative ideas and design ideas of the utility model can be realized in other specific forms without departing from the spirit or basic features of the utility model, which should be equivalent to the protection scope disclosed in the technical solution of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
