Description

Technical Field

[0001] The invention relates to the technical field of tobacco machinery, in particular to a feed tobacco shred breaking device for a tobacco shred drying machine. Background Art

[0002] The cut tobacco dryer is a crucial piece of equipment in the tobacco production line of a cigarette factory. Its primary function is to ensure that the moisture content of the tobacco exiting the dryer meets the requirements of the cigarette-making process, thereby improving the tobacco's yield and filling value, altering its physical properties, and mellowing its flavor. The cut tobacco drying process is crucial for improving its filling power, as the moisture content of the tobacco significantly influences its filling power. The looser and more curled the tobacco, the greater its filling power.

[0003] Most current tobacco dryers use vibrating conveyors to directly transport cut tobacco, resulting in poor drying performance at varying degrees, particularly the "dry ends" phenomenon. Over time, as cigarette batches are produced, a large amount of "dry ends" of cut tobacco accumulates. Due to process requirements, this "dry ends" needs to be further dried before being discharged, but is often simply discarded, resulting in a significant waste of resources.

[0004] At the same time, the moisture content of the processed tobacco fluctuates greatly, which can easily cause the tobacco to become loose and difficult to handle later or to become moldy. Especially when the moisture content of the dried tobacco is high and the stacking is not loose, it is not conducive to the subsequent drying effect and reduces the drying efficiency. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a device for breaking up the feed tobacco for a tobacco drying machine, so as to solve the problem pointed out in the background technology that the existing device is prone to the phenomenon of "dry head and dry tail", resulting in waste of tobacco, and at the same time, affecting the drying effect of tobacco and reducing the drying efficiency.

[0006] The present invention solves the above technical problems through the following technical means:

[0007] A tobacco feed breaking-up device for a tobacco drying machine comprises a conveyor and a tobacco drying machine, wherein the tobacco drying machine is arranged at one end of the conveyor, a mounting frame is provided on the tobacco drying machine, a hydraulic cylinder is provided on the mounting frame, a piston of the hydraulic cylinder is fixedly connected to a mounting column, pushing components are provided on both sides of the mounting column, a breaking-up component is provided on one side of the pushing component, cleaning components are provided on both sides of the mounting frame, a temperature sensor is provided in the tobacco drying machine, an image detector is provided on the conveyor, the temperature sensor and the image detector are both electrically connected to a controller, and the tobacco drying machine and the conveyor are both electrically connected to the controller.

[0008] Furthermore, the loosening assembly includes a first mounting base and a second mounting base, wherein a first tooth pin is fixedly connected to the bottom of the first mounting base, the first mounting base and the second mounting base are fixedly connected, and a second tooth pin is fixedly connected to the bottom of the second mounting base. In this arrangement, when in use, the first tooth pin and the second tooth pin are inserted into the tobacco to loosen the tobacco.

[0009] Furthermore, the second mounting base is provided with a plurality of first slots, and the second tooth pins are fixedly connected to first clamping blocks. In this arrangement, by inserting the first clamping blocks into different first slots, the first tooth pins and the second tooth pins are arranged crosswise, and the second tooth pins cooperate with the first tooth pins to adjust the size of the gap through which the tobacco shreds pass, thereby facilitating the adjustment of the looseness of the tobacco shreds.

[0010] Furthermore, one of the pushing assemblies is horizontally rotated 180° relative to the other pushing assembly about the central axis of the mounting post and has the same structure. This arrangement achieves the effect of simultaneously pushing the two first mounting seats forward and backward in opposite directions, thereby pulling the tobacco together and loosening any clumped tobacco. This solves the problem of hindering the subsequent drying effect and reducing drying efficiency when the dried tobacco has a high moisture content and is not loosely stacked.

[0011] Furthermore, the pushing assembly includes a fixed plate and a telescopic member. The fixed plate is fixedly connected to the first mounting base. One end of the telescopic member is fixedly mounted on one side of the mounting post. The free end of the telescopic member is fixedly connected to the fixed plate. The first mounting base is movably connected to the mounting post. In this arrangement, when the device is in operation, the electric telescopic rod is activated to push the first mounting base forward and backward.

[0012] Furthermore, a slider is fixedly connected to the mounting post, and a slide groove is provided on a side of the first mounting seat close to the mounting post, and the slider is movably connected in the slide groove. This arrangement facilitates the first mounting seat to move forward and backward along the slide groove relative to the mounting post.

[0013] Furthermore, the cleaning assembly includes a mounting plate and bristles, the mounting plate being fixedly connected to the mounting frame, the bristles being fixedly mounted on the mounting plate, and the bristles being perpendicular to the first and second tooth spikes. With this arrangement, when the first and second tooth spikes come into contact with the bristles during their ascent, the bristles clean the tobacco shreds adhering to the first and second tooth spikes, thereby preventing the tobacco shreds adhering to the first and second tooth spikes from remaining in the next use, thereby affecting the purity of the next batch of tobacco shreds.

[0014] Furthermore, both sides of the mounting frame are fixedly mounted on the conveyor, and fastening bolts are provided between the mounting frame and the conveyor, so as to fix the mounting frame and prevent it from shaking at will.

[0015] Furthermore, the bristles are made of a flexible and soft material so as to avoid affecting the rise or fall of the first mounting seat and the second mounting seat.

[0016] The present invention has the following advantages:

[0017] 1. Through the mutual cooperation of the hydraulic cylinder, the telescopic member, the first mounting seat, the second mounting seat, the first tooth nail and the second tooth nail, the effect of simultaneously pushing the two first mounting seats forward and backward or in the opposite direction is achieved, that is, the tobacco is pulled against each other, so that the clumped tobacco becomes loose, thereby improving the drying efficiency and achieving a better drying effect;

[0018] 2. Through the cooperation of the temperature sensor, controller and conveyor, when the temperature sensor detects the temperature inside the tobacco dryer, it sends a temperature signal to the controller. After analyzing and processing the signal, the controller controls the conveying rate of the conveyor, thereby achieving the purpose of controlling the amount of tobacco delivered to the tobacco dryer within a certain period of time. In other words, the amount of tobacco delivered is based on the drying temperature in the tobacco dryer, so that the dryness of the tobacco at the smoke outlet of the tobacco dryer is consistent. At the same time, the phenomenon of "dry at the beginning and dry at the end" is avoided, thereby avoiding waste of resources.

[0019] 3. The hydraulic cylinder, the bristles, the first tooth nails and the second tooth nails cooperate with each other to achieve the purpose of cleaning the tobacco attached to the first tooth nails and the second tooth nails, thereby preventing the tobacco attached to the first tooth nails and the second tooth nails from remaining in the next use, thereby affecting the purity of the next batch of tobacco.

[0026] like Figure 1 As shown, a tobacco feed loosening device for a tobacco drying machine of the present invention comprises a conveyor 1 and a tobacco drying machine 2. The tobacco drying machine 2 is rotatably mounted at one end of the conveyor 1. A mounting bracket 3 is provided on the conveyor 1. In this embodiment, both sides of the mounting bracket 3 are clamped to the conveyor 1. Fastening bolts 31 are secured between the mounting bracket 3 and the conveyor 1. A hydraulic cylinder 32 is bolted to the top of the mounting bracket 3. The piston of the hydraulic cylinder 32 is bolted to a mounting post 5, facilitating the upward and downward movement of the mounting post 5. In this embodiment, the conveyor 1 and tobacco drying machine 2 are both existing devices, so they will not be described in detail here.

[0027] like Figure 2 As shown, in this embodiment, pushing components are provided on both sides of the mounting column 5, and a breaking component is provided on one side of each pushing component, so that the purpose of moving the breaking component back and forth is achieved by the pushing component.

[0028] like Figure 3As shown, one set of the loosening assembly is described. The loosening assembly includes a first mounting seat 6 and a second mounting seat 61. A first tooth pin 62 is secured to the bottom of the first mounting seat 6. The first mounting seat 6 and the second mounting seat 61 are mutually secured. In this embodiment, a second slot is defined on one side of the first mounting seat 6, and a second block 64 is welded to one side of the second mounting seat 61. Multiple second slots and blocks 64 are provided, preferably five, to facilitate installation and removal of the second mounting seat 61. A second tooth pin 63 is secured to the second mounting seat 61. In this embodiment, a plurality of first slots 65 are defined on the second mounting seat 61. A first block 66 is welded to the second tooth pin 63. Multiple first blocks 66 are provided, preferably three. By inserting the first blocks 66 into different first slots, the first tooth pins 62 and the second tooth pins 63 are arranged crosswise. The interaction between the second tooth pins 63 and the first tooth pins 62 adjusts the size of the gap through which the tobacco passes, thereby facilitating adjustment of the degree of loosening of the tobacco.

[0029] like Figure 2 As shown, in this embodiment, the pushing assembly is arranged between the first mounting seat 6 and the mounting column 5, and one of the pushing assemblies is horizontally rotated 180° around the central axis of the mounting column 5 relative to the other pushing assembly, and has the same structure, so as to achieve the effect of simultaneously pushing the two first mounting seats 6 forward and backward in opposite directions, that is, to achieve the purpose of pulling the tobacco shreds against each other and making the lumped tobacco shreds loose; it solves the problem that when the moisture content of the dried tobacco shreds is high and the stacking is not too loose, it is not conducive to the later drying effect and reduces the drying efficiency. In this embodiment, one of the push assemblies is used for illustration. The push assembly includes a fixed plate 54 and a telescopic member 53. The fixed plate 54 is fixedly connected to the first mounting seat 6 by bolts. One end of the telescopic member 53 is fixedly mounted on one side of the mounting post 5 by bolts. The free end of the telescopic member 53 is fixedly connected to the fixed plate 54 by bolts. A slider is fixedly connected to the mounting post 5 by bolts. A slide 67 is defined on one side of the first mounting seat 6. The slider 52 is movably connected within the slide 67. The telescopic member 53 is preferably an electric telescopic rod. When the device is in operation, the electric telescopic rod is activated to push the first mounting seat 6 forward and backward along the slide 67, thereby driving the scattering assembly to move forward and backward. In this embodiment, the electric telescopic rods on both sides of the mounting post 5 operate at the same frequency and in opposite directions, so that the scattering assemblies on both sides work together well, achieving a good pulling effect.

[0030] like Figure 1As shown, in this embodiment, an image detector is fixedly installed on the conveyor 1 via bolts. The image detector is electrically connected to a controller. The tobacco drying machine 2, conveyor 1, hydraulic cylinder 32, and electric telescopic rod are all electrically connected to the controller. When the image detector detects that there are clumps of tobacco on the conveyor 1, it sends a signal to the controller, which activates the hydraulic cylinder 32 through the controller, causing the breaking assembly to move down to the working surface of the conveyor 1. The breaking up of the clumps of tobacco is completed by the mutual coordination of the pushing assembly and the breaking assembly, and then returns to its original position after completion. After the clumps of tobacco are broken up, the subsequent drying efficiency is higher and a better drying effect is achieved. In this embodiment, the image detector is an existing device that uses a processor to analyze images after collecting them. It is used to detect whether there are clumps of tobacco on the conveyor 1, so it will not be described in detail here.

[0031] like Figure 2 As shown, cleaning components are provided on both sides of the mounting frame 3. In this embodiment, the cleaning components include a mounting plate 4 and bristles 41. The mounting plate 4 is fixedly connected to the mounting frame 3 by bolts. The bristles 41 are glued to the mounting plate 4. The bristles 41 are made of a flexible and soft material to prevent them from affecting the rise or fall of the first mounting seat 6 and the second mounting seat 61; the bristles 41 are perpendicular to the first tooth nail 62 and the second tooth nail 63. When the device is not in use, the hydraulic cylinder 32 is started to make the first tooth nail 62 and the second tooth nail 63 rise, so that they are away from the tobacco conveying surface of the conveyor 1. When the first mounting seat 6 and the second When the mounting seat 61 contacts the bristles 41, the bristles 41 are deformed, facilitating the ascent of the first mounting seat 6 and the second mounting seat 61. When the bottoms of the first mounting seat 6 and the second mounting seat 61 begin to contact the bristles 41, the bristles 41 begin to reset from bottom to top. At this time, the bottom bristles 41 contact the rising first tooth nails 62 and the second tooth nails 63, and the tobacco attached to the first tooth nails 62 and the second tooth nails 63 are cleaned by the bristles 41, avoiding the tobacco attached to the first tooth nails 62 and the second tooth nails 63 from remaining in the next use, thereby affecting the purity of the next batch of tobacco.

[0032] like Figure 1 As shown, in this embodiment, a temperature sensor is fixedly installed in the tobacco dryer 2 by bolts, and the temperature sensor is electrically connected to the controller. When the temperature sensor detects the temperature in the tobacco dryer 2, it sends a signal indicating the temperature to the controller. After analyzing and processing the signal, the controller controls the conveying rate of the conveyor 1, thereby achieving the purpose of controlling the amount of tobacco delivered to the tobacco dryer 2 within a certain period of time, that is, the amount of tobacco delivered is adjusted according to the drying temperature in the tobacco dryer 2, so that the degree of dryness of the tobacco at the smoke outlet of the tobacco dryer 2 is consistent; at the same time, the phenomenon of "dry head and dry tail" is avoided, thereby avoiding waste of resources.

[0033] The operating principle of the present invention is as follows:

[0034] First, when the image detector detects that there are clumped tobacco on the conveyor 1, it sends a signal to the controller, which starts the hydraulic cylinder 32 through the controller. The expansion and contraction of the piston of the hydraulic cylinder 32 drives the mounting column 5 to descend, thereby driving the first tooth nail 62 and the second tooth nail 63 to descend, so that they touch the tobacco conveying surface of the conveyor 1. Then the controller starts the electric telescopic rod to achieve the effect of pushing the two first mounting seats 6 forward and backward or in the opposite direction at the same time, that is, pulling the tobacco together to loosen the lumps of tobacco. This solves the problem that when the moisture content of the dried tobacco is high and the stacking is not too loose, it is not conducive to the later drying effect and reduces the drying efficiency.

[0035] At the same time, when the temperature sensor detects the temperature inside the tobacco dryer 2, it sends a signal indicating the temperature to the controller, which analyzes and processes the signal and then controls the conveying rate of the conveyor 1 through the controller, thereby achieving the purpose of controlling the amount of tobacco delivered to the tobacco dryer 2 within a certain period of time, that is, the amount of tobacco delivered according to the drying temperature in the tobacco dryer 2 is made to have a uniform degree of dryness at the smoke outlet of the tobacco dryer 2; at the same time, the phenomenon of "dry head and dry tail" is avoided, thereby avoiding waste of resources.

[0036] After use, the hydraulic cylinder 32 is started by the controller to raise the first tooth nail 62 and the second tooth nail 63, so that it is away from the tobacco conveying surface of the conveyor 1. When the first mounting seat 6 and the second mounting seat 61 contact the bristles 41, the bristles 41 are deformed, which facilitates the rise of the first mounting seat 6 and the second mounting seat 61. When the bottom of the first mounting seat 6 and the second mounting seat 61 begins to contact the bristles 41, the bristles 41 begin to reset from bottom to top. At this time, the bottom bristles 41 contact the rising first tooth nail 62 and the second tooth nail 63, and the tobacco attached to the first tooth nail 62 and the second tooth nail 63 are cleaned by the bristles 41 to avoid the tobacco attached to the first tooth nail 62 and the second tooth nail 63 from remaining in the next use, thereby affecting the purity of the next batch of tobacco.

[0037] The above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that the technical solutions of the present invention may be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention, and such modifications or equivalents shall be encompassed by the claims of the present invention.
