Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production equipment, specifically, it is a device for improving the feeding uniformity of cut tobacco in the processes of loosening and conditioning. Background Art

[0002] The slicing of tobacco bales is a processing process in which the tobacco bales are cut into several pieces of cut tobacco after the tobacco bales are opened in the process of tobacco processing. The slicing assembly consists of a main frame, a cross beam, etc. to form a solid platform. The blades are fixed on the fixed blade plates, and the fixed blade plates are fixed on a pair of traveling frames. These traveling frames are equipped with four guiding rollers, and the rollers can move up and down along the tracks fixed on the main frame.

[0003] Since the cut tobacco directly falls onto the belt after being sliced by the blades, due to the height difference and inconsistent dumping directions, the cut tobacco is often irregularly placed on the belt. If the cut tobacco is not placed regularly, there will be gaps or large pieces on the conveyor belt for feeding in the processes of loosening and conditioning, and the flow rate is unstable, which will affect the effect of loosening and conditioning the cut tobacco, and lead to problems such as poor quality of cut tobacco in processing and large breakage.

[0004] At the same time, due to the large height difference between the slicing machine and the belt, and between the belt and the feeding opening of the loosening and conditioning process, the whole cut tobacco falls by using the height difference, which will cause a greater impact on the cut tobacco, and further cause breakage of the cut tobacco.

[0005] Under the industry background of "energy conservation and consumption reduction", "two improvements and two reductions", etc., reducing the breakage of cut tobacco after slicing and increasing the looseness of cut tobacco are of great significance. Content of the Utility Model

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Embodiment:

[0033] Combined with the attached Figure 1-6 As shown, a device for improving the feeding uniformity of cut tobacco during loosening and conditioning includes: a slicing machine 1, a clamping assembly 4, a slicing guide plate 5 of the flow guiding plate assembly, a belt 6, a belt guide plate 8, and an auxiliary power system, a control system, etc.; clamping assemblies 4 are arranged on both sides of the cutter of the slicing machine 1, and a slicing guide plate 5 is arranged below. The slicing guide plate 5 is located above one end of the belt 6 and is used to transition the cut tobacco after slicing and loosening to the belt for transportation; a belt guide plate 8 is arranged at the other end of the belt and is used to guide the cut tobacco from the belt to the vibrating trough 9 so as to be transmitted into the loosening and conditioning machine 10 of the next process.

[0034] Preferably, there is a flow guiding assembly 7 above the connection between the belt guide plate 8 and the belt. The flow guiding assembly is in a curved surface shape and bends towards the side of the belt guide plate 8 away from the belt 6. The flow guiding assembly is movably arranged above the connection between the belt guide plate and the belt to adapt to the height of the cut tobacco. Through the combined action of the flow guiding assembly and the belt guide plate, the cut tobacco is loosened layer by layer from the belt to the next process, preventing the cut tobacco from falling entirely into the feeding port of the loosening and conditioning machine, and helping the cut tobacco to be layered and increasing the looseness of the cut tobacco.

[0035] During operation, the slicing machine 1 transports the tobacco bale forward. The protruding part of the tobacco bale is clamped by the clamping assemblies 4 on both sides of the cutter 3 of the slicing machine 1. After slicing is completed by the cutter, the clamping assemblies apply a certain force to moderately loosen the cut tobacco; then the clamping assemblies are released, and the cut tobacco slides onto the slicing guide plate 5 below the cutter of the slicing machine 1. The guide plate has a certain slope to prevent the impact caused by the cut tobacco falling by gravity, reduce the breakage of the cut tobacco, and prevent the position or order of the cut tobacco from being disordered; the cut tobacco is then transitioned from the slicing guide plate to the belt and conveyed to the belt guide plate 8. The flow guiding assembly above the connection between the belt guide plate 8 and the belt prevents the cut tobacco from falling entirely into the feeding port of the loosening and conditioning machine, and helps the cut tobacco to be layered and increases the looseness of the cut tobacco. The cut tobacco falls into the loosening and conditioning machine 10 through the vibrating trough 9 one by one. The device has a simple structure, is convenient to transform, has a low cost and good effects, effectively solves the problems of the cut tobacco being inverted and horizontal after cutting, improves the feeding uniformity of the loosening and conditioning process of the cut tobacco, and greatly improves the loosening rate of the loosening and conditioning.

[0036] In one embodiment, the clamping assembly is connected to the PLC controller 2 to control the clamping assembly through the PLC controller. The side clamping assembly for sliced cut tobacco is designed to ensure that both sides of the tobacco bale are fixed without tilting and spreading out, ensuring that the cut tobacco falls onto the slicing deflector in a regular order. And the clamping assembly can apply a certain force to the cut tobacco under the control of the PLC controller 2 for moderate loosening of the cut tobacco. This clamping assembly can solve the problem that the cut tobacco on the side of the tobacco bale spreads out to both sides under the cutting force of the cutter during slicing, preventing the formation of adhered tobacco blocks.

[0037] In one embodiment, the clamping assembly is driven by a cylinder because compressed air is commonly arranged in existing workshops, easy to obtain, easy to implement, and has low installation and maintenance costs in the early stage and has no impact on production.

[0038] In one embodiment, the pressure of the clamping assembly is adjustable and can be adjusted and controlled within the range of 0.1 - 0.6 MPa according to the type of cut tobacco and actual requirements.

[0039] Specifically, two groups of clamping assemblies 4 are installed on both sides of the cutter 3 of the slicing machine. The clamping assembly mainly consists of a scissor mechanism composed of a base 4.1, a clamping plate 4.2, a clamping cylinder 4.3, a clamping roller 4.4, a connecting bracket 4.5, etc. The base 4.1 is fixed to the body of the slicing machine through the connecting bracket 4.5. The clamping plate 4.2 is a movable part and is movably arranged on the base 4.1. The clamping cylinder 4.3 is arranged inside the base 4.1. The extension and retraction of the clamping plate 4.2 are realized through two clamping cylinders 4.3, which has the characteristics of adjustable extension length, large clamping force, and small space occupation after retraction. A number of clamping rollers 4.4 are installed inside the clamping plate 4.2. The clamping rollers are power-free rollers and can rotate around their own axes. When the slicing deflector 5 descends to discharge materials, the cut tobacco 12 after cutting drives the clamping rollers to rotate by its own gravity, and the cut tobacco 12 after cutting slowly slides onto the belt 6 to achieve flexible material dropping. The initial retraction speed of the clamping cylinder 4.3 can also be controlled by a one-way throttle valve to match the flexible material dropping process of the cut tobacco after cutting.

[0040] In one embodiment, the slicing deflector receives the cut tobacco released by the clamping assembly and allows the cut tobacco to slide onto the belt. The slicing deflector can be rotatably arranged at 30° - 60° to reduce the impact force of the cut tobacco on the belt and reduce breakage.

[0041] Specifically, the deflector assembly includes a slicing deflector 5, a deflector cylinder 5.1, and a connecting plate 5.2. The slicing deflector 5 is in an inverted "L" shape, and one side thereof is matched with the slicing machine body to limit the inclination angle of the slicing deflector. Of course, the inclination angle can also be controlled by other means. One end of the deflector cylinder 5.1 is fixedly arranged on the slicing machine body, and the other end is rotatably connected to the connecting plate 5.2 installed at the end of the slicing deflector 5. By the telescopic movement of the deflector cylinder 5.1, the connecting plate 5.2 is driven to rotate, thereby driving the slicing deflector 5 to rotate, and conducting the cut tobacco on the slicing deflector 5 to the belt. When the deflector cylinder 5.1 extends, the top of the inverted "L" shape of the slicing deflector 5 is horizontal, and together with the clamping assembly 4, the cigarette packet 11 is firmly fixed, enabling the cutter 3 to smoothly cut the cut tobacco. After cutting, the cut tobacco 12 is unloaded through the combined cooperation of the rotation of the slicing deflector 5 and the clamping assembly 4, reducing the impact force of the cut tobacco on the belt and reducing breakage.

[0042] In an embodiment, preferably, the included angle between the deflector assembly 7 and the belt is set at 45°, ensuring that the cut tobacco is further loosened and does not fall in a clumped state. The belt deflector 8 is bent away from the deflector assembly 7, and the bending angle is set at 30° - 60°, reducing the impact force of the cut tobacco on the belt and reducing breakage.

[0043] Specifically, the deflector assembly 7 includes two base frames 7.9 with a certain amount of movement, and a number of main drive rollers 7.4 and idle rollers 7.12 arranged inside the base frames. Through the combined action of the main drive rollers 7.4 and the idle rollers 7.12, the cut tobacco is driven to disperse and fall from the belt to the belt deflector and then to the loose and re-dampening machine. Preferably, the two base frames 7.9 are connected into one body by a fixed cross beam 7.10 and are connected to the main supports 7.7 on both sides of the belt through bearings. The main supports 7.7 are fixedly connected to both sides of the body of the belt. At the same time, the base frames 7.9 and the spring supports 7.2 fixedly connected to the body of the belt 6 form a buffer spring assembly through upper and lower buffer springs 7.1, realizing a certain movement buffer function of the deflector assembly 7, adapting to the height change of the cut tobacco 12 after cutting, and preventing blockage and cigarette jamming in the channel between the belt 6 and the deflector assembly 7.

[0044] The main drive rollers 7.4 are arranged at the inlet of the deflector assembly 7 and are driven by the main reduction motor 7.3. The main drive rollers 7.4 and the belt 6 jointly feed the cut tobacco 12 after cutting. At the same time, two driven rollers 7.11 are also arranged in the deflector assembly 7 to assist in guiding and conveying the cut tobacco 12 at the position where the center of gravity changes during the conveying process of the cut tobacco 12 on the belt 6. The driven sprockets 7.6 are driven by the drive sprockets 7.5 connected to the main drive rollers 7.4. The driven sprockets 7.6 arranged on both sides drive the driven rollers 7.11. There is an intermediate transition sprocket 7.8 between the two groups of driven sprockets, and the intermediate transition sprocket 7.8 only transmits power and does not participate in driving.

[0045] The diversion assembly 7 is also provided with a plurality of non-powered rollers 7.12, which are rotated passively by the belt driving force and the action of cut tobacco sheets. Its function is to guide the cut tobacco sheets 12 after cutting, prevent the impact of the cut tobacco sheets, and through driving and guiding, the cut tobacco sheets 12 after cutting slide into the belt diversion plate 8 and then enter the vibrating trough 9, thereby reducing the impact. The cut tobacco sheets 12 after cutting are a laminated structure. Some of the cut tobacco sheets 12 are at the outlet position of the belt 6. The rear part of the cut tobacco sheet is suspended, while the front part is still between the diversion assembly roller and the belt. Due to the change of the center of gravity, the rear part will be stratified and separated, and will fall into the diversion plate 8 in advance and then enter the vibrating trough 9, thereby realizing the pre-loosening function.

[0046] Although the present invention has been described herein with reference to illustrative embodiments of the present invention, the above embodiments are only preferred embodiments of the present invention, and the embodiments of the present invention are not limited by the above embodiments. It should be understood that those skilled in the art can design many other modifications and embodiments, and these modifications and embodiments will fall within the scope and spirit of the principles disclosed in this application.
