Description

Technical Field

[0001] The utility model relates to the technical field of tobacco, and particularly relates to a triangular two-side type blowing baffle at the material dropping port of a belt conveyor. Background Art

[0002] The conveyor belt is used in the tobacco leaf making and threshing and redrying production lines to convey various tobacco materials such as tobacco leaves, tobacco leaves, tobacco stems, and cut tobacco, meeting the requirements of the interfaces of each main equipment and conveying materials as auxiliary connection equipment. According to different process requirements, the conveyor belt can also have functions such as removing metals, removing waste materials, and feeding at fixed points. The conveyor belt has the advantages of simple structure, convenient operation, and flexible use.

[0003] The interface baffle of the existing conveyor belt in the cigarette making workshop is of an inverted trapezoid side type. During the feeding process of several connected conveyor belts, when the previous conveyor belt conveys materials to the next conveyor belt, with the accumulation of time, it is easy to gradually accumulate tobacco materials such as cut tobacco, tobacco leaves, and stem silk at the interfaces of adjacent conveyor belts, which will cause the following impacts: If the on-duty personnel do not clean or clean incompletely during the same batch, it will affect the balance of the material flow rate, the control of moisture and temperature; When the on-duty personnel clean, it is easy to mix other sundries, broom shavings, etc. into the tobacco materials and flow into the next process, causing quality accidents; Since a large number of conveyor belts are used in the cigarette making workshop as tobacco material conveying equipment, if the accumulated materials at each adjacent interface are not cleaned in time, it will greatly increase the material consumption, cause a large amount of waste, and increase the manufacturing cost. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a triangular two-side type blowing baffle at the material dropping port of a belt conveyor, which solves the problems of easy material accumulation at the material dropping port of the traditional conveyor belt, resulting in material waste, quality accidents, and inconvenient operation.

[0005] The technical problem to be solved by the utility model is realized through the following technical solutions:

[0006] A triangular two-side type blowing baffle at the material dropping port of a belt conveyor includes:

[0007] A baffle, which includes a material dropping port bottom baffle, and material dropping port side baffles are symmetrically arranged on both sides of the material dropping port bottom baffle; Air-permeable fine wire through-hole nets are arranged at the bottoms of the material dropping port bottom baffle and the material dropping port side baffles, and a rubber wear-resistant skirt is arranged below the air-permeable fine wire through-hole nets, and the rubber wear-resistant skirt is in contact with the conveyor belt.

[0008] A compressed air jet pipe, which is arranged at the rear of the breathable dense wire through-hole net. The compressed air jet pipe is provided with air vents, and the compressed air jet pipe is connected to an air source;

[0009] A compressed air nozzle, which is arranged at the included angle between the bottom baffle of the material dropping port and the upper end of the side baffle of the material dropping port. The compressed air nozzle is connected to an air source;

[0010] A control device, which includes a button, a controller and a PLC. The controller receives the signal sent by the button and controls the on-off of the compressed air jet pipe and the compressed air nozzle through a solenoid valve. The PLC receives the signal sent by the button. After the controller controls the solenoid valve to conduct the air source, the time-delay relay in the PLC times for a certain period of time and then automatically sends a signal to the solenoid valve to close the air sources of the compressed air nozzle and the compressed air jet pipe.

[0011] Preferably, the included angle between the side baffle of the material dropping port and the conveyor belt is 75°.

[0012] Preferably, the breathable dense wire through-hole net is made of food-grade stainless steel.

[0013] Preferably, the compressed air nozzle is angled downward at 60°.

[0014] Preferably, the air vents are angled downward at 15°, and the pressure of the compressed air ejected from the air vents is 1.5 bar.

[0015] Preferably, the rubber wear-resistant skirt is made of wear-resistant and heat-resistant material.

[0016] Preferably, the input end of the controller is connected to the output end of the button, the output end of the controller is connected to the input end of the solenoid valve, and the solenoid valve is used to receive the signal from the controller.

[0017] Preferably, after the controller controls the solenoid valve to conduct the air source, the time-delay relay in the PLC starts timing simultaneously. After 35 seconds, the PLC sends a signal to the solenoid valve to automatically cut off the air sources in the compressed air jet pipe and the compressed air nozzle.

[0018] The above technical solution of the present utility model has the following beneficial effects:

[0019] The utility model can prevent tobacco materials such as cut tobacco, tobacco leaves, and sesame slices from accumulating at the blanking port of the conveyor, replacing manual cleaning of the accumulated materials. It avoids the impact on the balance of material flow, moisture, and temperature control if the on-duty personnel fail to clean or clean incompletely during the same batch. It also avoids the quality accidents caused by the mixing of other sundries, broom shavings, etc. into the tobacco materials during the cleaning by on-duty personnel and flowing into the next process. Since a large number of conveyor belts are used as tobacco material conveying equipment in the silk-making workshop, the accumulated materials at each adjacent interface are cleaned in time, which will greatly reduce material consumption, waste, and significantly reduce the manufacturing cost of cigarette production.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Now, various exemplary embodiments of the utility model will be described in detail with reference to the drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the utility model.

[0027] A triangular two-side type blowing baffle at the blanking port on a belt conveyor includes:

[0028] The baffle plate includes a bottom baffle plate 2 of the blanking port, and blanking port side baffle plates 6 are symmetrically arranged on both sides of the bottom baffle plate 2 of the blanking port; air-permeable fine wire through-hole nets 3 are arranged at the bottoms of the bottom baffle plate 2 of the blanking port and the blanking port side baffle plates 6, a rubberized wear-resistant skirt 7 is arranged below the air-permeable fine wire through-hole net 3, and the rubberized wear-resistant skirt 7 is in contact with the bottom conveyor belt 8;

[0029] The compressed air jet pipe 4 is arranged at the rear of the air-permeable fine wire through-hole net 3, air vent holes 5 are arranged on the compressed air jet pipe 4, and the compressed air jet pipe 4 is connected to a gas source;

[0030] The compressed air nozzle 1 is arranged at the included angle between the upper ends of the bottom baffle plate 2 of the blanking port and the blanking port side baffle plates 6, and the compressed air nozzle 1 is connected to a gas source;

[0031] The control device includes a button 9, a controller 10 and a PLC 11. The controller 10 receives the signal sent by the button 9 and controls the on-off of the compressed air jet pipe 4 and the compressed air nozzle 1 through a solenoid valve 12. The PLC receives the signal sent by the button 9, and after the controller 10 controls the solenoid valve 12 to conduct the gas source, the time-delay relay 13 in the PLC counts for a certain period of time and then automatically sends a signal to the solenoid valve to close the gas sources of the compressed air nozzle 1 and the compressed air jet pipe 4.

[0032] Further, the blanking port side baffle plate 6 is made of food-grade stainless steel. As the side baffle plates of the conveyor belt 8, it forms a shape similar to a triangle in combination with the conveyor belt 8. The conveyor belt 8 is analogous to the bottom side of the triangle, and the two sides of the blanking port side baffle plates 6 are analogous to the two sides of the triangle. The included angle between the two blanking port side baffle plates 6 and the conveyor belt 8 changes from the original 105 degrees or 90 degrees to the current 75 degrees. The two blanking port side baffle plates 6 and the conveyor belt 8 are combined into a shape similar to a triangle to prevent material accumulation, so it is called a triangular side type baffle.

[0033] Further, the air-permeable fine wire through-hole net 3 is made of food-grade stainless steel. It is installed at the bottoms of the bottom baffle plate 2 of the blanking port and the two blanking port side baffle plates 6 and is integrated with the baffle plates. The through-holes of the air-permeable fine wire through-hole net 3 are extremely small. It can allow the compressed air ejected from the compressed air jet pipe 4 at the rear of the air-permeable fine wire through-hole net 3 to pass through without generating a large resistance while ensuring that tobacco materials such as cut tobacco, tobacco leaves, and sesame slices will not leak out from it.

[0034] Further, the compressed air nozzle 1 is fixed at the included angle between the left and right blanking port side baffle plates 6 and the bottom baffle plate 2 of the blanking port, and blows downward at 60° at certain intervals to blow away the materials that are likely to accumulate in the corners, without material accumulation and without leaving residual materials.

[0035] Furthermore, the compressed air jet conduit 4 is led out from the on-site compressed air tap. There are many ventilation holes 5 on the compressed air jet conduit 4. The ventilation holes 5 are made to be 15 degrees downward. The pressure of the compressed air ejected from the ventilation holes 5 is 1.5 bar, ensuring an appropriate pressure value so that the tobacco materials such as cut tobacco, tobacco leaves, and sesame slices accumulated at the bottom will not be crushed due to excessive pressure or ejected outside the bottom conveyor belt. Instead, they are blown onto the bottom conveyor belt by the compressed air nozzles, preventing the accumulation of materials in the edge area caused by long-term feeding.

[0036] Furthermore, the rubber wear-resistant skirt 7 is made of wear-resistant and heat-resistant material and is installed at the lower part of the breathable dense wire through-hole net 3, forming an integral body with the breathable dense wire through-hole net 3. The rubber wear-resistant skirt 7 contacts the bottom conveyor belt 8. Due to the material characteristics of the rubber, it can bend into the conveyor belt, thus reducing the gap with the bottom conveyor belt and preventing tobacco materials such as cut tobacco, tobacco leaves, and sesame slices from falling under the bottom conveyor belt through the side gaps, causing material waste and problems such as running, dripping, and leaking in on-site 6S management.

[0037] Furthermore, the input end of the controller is connected to the output end of the button, and the output end of the controller is connected to the input end of the solenoid valve. The solenoid valve is used to receive signals from the controller. Its function is to receive the signals sent by the button and control the solenoid valve to control the on-off of the two groups of compressed air nozzles 1 at the left and right included angles, and the three groups of compressed air jet conduits 4 of the bottom baffle and the side baffle at the feeding port.

[0038] Furthermore, the function of the solenoid valve is to receive signals from the controller and control the on-off between the compressed air source and the two groups of compressed air nozzles at the left and right included angles, and the three groups of compressed air jet conduit devices of the bottom baffle and the side baffle at the feeding port.

[0039] Furthermore, the main function of the PLC is to have a delay function. After the button sends a signal, one path goes to the controller and the other path goes to the PLC. After the controller controls the solenoid valve to conduct compressed air, the delay relay in the PLC starts timing simultaneously. After 35 seconds, the PLC sends a signal to automatically cut off the air source in the compressed air jet conduit 4 and the compressed air nozzle 1.

[0040] The triangular two-side type spray baffle at the feeding port of the belt conveyor of the present application is used as follows:

[0041] When each process produces the tail materials of the current batch, such as the cut tobacco leaf process, the tobacco drying process, etc., operators at each position should, according to the production situation of the tail materials in this process, press the button in advance when the tail materials are not completely produced. The button sends signals in two branches. One branch sends signals to the controller, and the other branch sends signals to the PLC. The controller sends signals to the solenoid valve, and the solenoid valve opens, enabling the on-site compressed air tap to connect to the two groups of compressed air nozzles 1 at the left and right angles, the three groups of compressed air jet pipes 4 at the bottom of the material discharge port baffle 2 and the side baffle 6 of the two side material discharge ports. The two groups of nozzles and the three groups of jet pipes start to ventilate, and compressed air sprays out from the ventilation holes 5 of the compressed air nozzles 1 and the compressed air jet pipes 4. According to the fixed angles (60 degrees, 15 degrees) and the set pressure value of 1.5 bar of the compressed air nozzles 1 and the compressed air jet pipes 4, the accumulated residual materials are blown, so that the materials at the angle and the bottom fall onto the conveyor belt 8 and are conveyed to the next link together with the tail materials. During the blowing process, the time-delay relay in the PLC starts timing simultaneously. After 35 seconds of blowing, the PLC sends signals to the solenoid valve, and the solenoid valve controls the automatic shut-off of the air sources of the nozzles and the jet pipes, preventing excessive blowing from causing breakage of tobacco materials such as accumulated cut tobacco, tobacco leaves, and sesame slices and preventing tobacco materials from falling outside the conveyor belt. At the same time, it prevents energy consumption caused by continuous blowing of the nozzles and air ducts due to the on-site operator forgetting to operate the button to close the compressed air. Thus, the blowing is completed during the production of the tail materials of the current batch, and all tobacco materials such as cut tobacco, tobacco leaves, and sesame slices generated by the accumulation of a single batch are conveyed to the next link together with the tail materials.

Any person skilled in the art can make various different selections and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model is defined by the claims and their equivalent forms.
