[0003] At present, there are certain disadvantages in the discharge of tobacco cake rollers from the bottom of the storage cabinet and the evacuation of bundles or packages of tobacco. Since irregular guide rods are arranged on the cake rollers, the guide rods on the cake rollers are easily broken due to reverse pressure under the influence of the resistance of wet tobacco during continuous operation. At the same time, high-hardness foreign objects mixed in the tobacco are difficult to be picked out by workers in time, and the continuously rotating cake rollers will also bring certain safety hazards to the workers' selection.

At this time, the workers can safely select the foreign objects inside the silo.

[0039] 3. The present invention opens dense sieve holes at the bottom of the silo. With the high-frequency vibration of the two baffle plates, the vibration waves will radiate to the silo. At this time, the tobacco inside the silo and loosened by multiple material rollers can shake out impurities with the help of the shock waves. At the same time, the aqueous solution accumulated in the tobacco can also be emptied along the sieve holes, thereby effectively improving the cleanliness of the tobacco.

DETAILED DESCRIPTION

[0059] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0060] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0061] A tobacco storage cabinet rake roller safety protection device provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0062] Embodiment 1:

[0063] Combination Figure 1-Figure 13 As shown, a tobacco storage cabinet rake roller safety protection device provided by the present invention includes a tobacco delivery mechanism 100, an energy supply mechanism 200 arranged on the tobacco delivery mechanism 100, a material cutting mechanism 400 arranged on the tobacco delivery mechanism 100, a plurality of infrared detectors 300 arranged on the tobacco delivery mechanism 100, and a material removal mechanism 500 arranged on the tobacco delivery mechanism 100, the tobacco delivery mechanism 100 is used to provide a platform for co-delivery and vibration screening of tobacco, the energy supply mechanism 200 is used to provide kinetic energy for tobacco vibration screening and impurity removal, the infrared detector 300 is used to detect and pre-tighten the foreign objects shaken out, the material cutting mechanism 400 is used to shake out bundles or packages of tobacco and block the foreign objects shaken out, and the material removal mechanism 500 is used to evacuate tobacco.

[0064] The tobacco delivery mechanism 100 includes a silo 140 and two load-bearing beams 110, two guard plates 150 disposed on the top of the silo 140, four sets of distance adjustment components 180 disposed on the silo 140, two suspensions 170 disposed on the two load-bearing beams 110, and horizontally mounted hydraulic components 190 installed in the two suspensions 170;

[0065] The inner sides of the two load-bearing beams 110 are both installed with upright posts 130 , and two sets of horizontal bars 120 are installed in the two load-bearing beams 110 ;

[0066] The energy supply mechanism 200 includes a chassis 210 disposed on one of the suspensions 170 , a motor 220 is disposed inside the chassis 210 , and a driving wheel 230 and a deflection wheel 250 are mounted on a transmission shaft inside the motor 220 ;

[0067] The driving wheel disc 230 is transmission-connected with a crawler belt 240, and the other end of the crawler belt 240 is transmission-connected to one of the transmission ends 536;

[0068] A striker 260 is movably mounted on the guide rod that deviates from the circular shape outside the deflection wheel 250;

[0069] The other end of the striker 260 is disposed on a material blocking plate 440 of the crane;

[0070] The material cutting mechanism 400 includes four legs 410 and four brackets 430 , and four first compression springs 420 are respectively disposed on the four legs 410 and the four brackets 430 ;

[0071] A material blocking plate 440 is installed on two adjacent brackets 430, and two other positioning members 450 are symmetrically arranged in the end plates at both ends of the material blocking plate 440;

[0072] A second compression spring 470 is disposed outside the positioning member 450 , and a gasket 460 is installed at the top end of the positioning member 450 ;

[0073] Two symmetrically distributed cross frames 480 are fixedly installed at the bottom of the two baffle plates 440;

[0074] The dough mechanism 500 includes two groups of roller body rotation-assisting assemblies 530, three roller body rotation-assisting assemblies 530 disposed in the two groups of roller body rotation-assisting assemblies 530, and two protective rollers 510 disposed in the two groups of roller body rotation-assisting assemblies 530;

[0075] The two groups of roller rotation-assisting assemblies 530 are used to provide a common driving force for the three roller rotation-assisting assemblies 530 and the two protective rollers 510 , and provide a free clamping force for the three roller rotation-assisting assemblies 530 .

[0076] Since tobacco processing involves many steps, the links that require the use of tobacco cakes are mainly the evacuation of tobacco bundles or packages and the discharge of wet materials in the storage cabinet. The tobacco in these two links has a large resistance to the tobacco cake roller, especially the processing of wet tobacco. Once the tobacco cake roller rotates too fast, it will be disturbed by the excessive resistance and the rod on the tobacco cake will break. In serious cases, it will interfere with the subsequent process. At the same time, the broken rod will also cause safety hazards to workers.

[0077] In addition, there will still be certain foreign matter in the tobacco after it is evacuated on the assembly line, and it is difficult for workers to find it in time if it is mixed inside the tobacco. At the same time, after it is found, it is affected by the tobacco rollers and it is inconvenient to clean up the foreign matter.

[0078] The device is arranged in two processing links according to the use requirements. After the tobacco is delivered to the inside of the silo 140, the internal transmission shaft of the running motor 220 will drive the driving wheel 230 and the deflection wheel 250 to rotate, and the crawler 240 driven by the driving wheel 230 will drive the transmission end 536. At this time, the two chains 538 are linked, and the transmission end 536 arranged on the protective roller 510 can drive multiple linkage ends 535 to rotate stably. At this time, the evenly distributed multiple tobacco rollers 520 can process the tobacco passing through the silo 140.

[0079] At the same time, after the deflection wheel 250 drives the striker 260 to vibrate at a high frequency, the two material blocking plates 440 that are pressurized can perform regular lifting activities along the inside of the two blocking grooves 160, and the tobacco can be initially broken up, and the foreign matter mixed in the tobacco after being broken up will be lifted upward, and the lifted foreign matter can be quickly detected and captured by the two infrared detectors 300 of set height, and at the moment of capture, the motor 220 and the hydraulic component 190 controlled by the electrical signal will be controlled, so as to block the detected foreign matter and the broken rod body, so as to facilitate the workers to carry out safe selection;

[0080] When an individual dough roller 520 is damaged, the chain 538 is picked out from the two linkage ends 535 outside the damaged dough roller 520. At this time, the damaged dough roller 520 can be quickly and safely replaced without interfering with the operation of other normal dough rollers 520.

[0081] Embodiment 2:

[0082] Combination Figure 3 and Figure 4 As shown, on the basis of Example 1, densely distributed sieve holes are provided at the bottom of the silo 140, and two symmetrically distributed blocking grooves 160 are provided at both ends of the silo 140;

[0083] The silo 140 is made of stainless steel.

[0084] Preferably, when the two combined baffle plates 440 are pushed and vibrated at high frequency, the impact force generated by the vibration will radiate to the silo 140, and finally the loose tobacco that passes through the inside of the silo 140 and is affected by the afterwave of the vibration can be vibrated to remove impurities, and finally impurities, moisture and the like can be quickly discharged from the rod sieve holes, thereby accelerating the cleaning efficiency of the tobacco.

[0085] The distance adjustment assembly 180 includes two support plates 181, one of which is disposed on the load-bearing beam 110, and the other support plate 181 is disposed on the pressure plate 531;

[0086] A slide plate 182 is disposed on the outer side of the support plate 181, and a reinforcing spring 183 is disposed between two adjacent slide plates 182;

[0087] A shell 185 is disposed outside the two slide plates 182, and two screw sleeves 186 are symmetrically disposed on the top and bottom of the shell 185;

[0088] A progressive screw rod 184 which is pressed by the slide plate 182 is arranged inside the screw sleeve 186 .

[0089] Preferably, the extension width between the two support plates 181 is controlled by adjusting the two progressive screw rods 184. When the two support plates 181 gradually lose the pressure of the two progressive screw rods 184, they are elastically supported by the reinforcing springs 183. The two support plates 181 can maintain a certain gap under the limit constraint of the outer shell 185. As the silo 140 vibrates as a whole, multiple groups of support plates 181 at a certain gap can provide the silo 140 with a larger amplitude, thereby facilitating the loosening of the tobacco cake material and increasing the drying efficiency of the moisture in the tobacco.

[0090] Embodiment 3:

[0091] Combination Figure 9-13 As shown, based on the embodiment 1, the roller body rotation assisting assembly 530 includes a pressure plate 531 and a pushing outer plate 534;

[0092] Three slots are provided inside the pressure-carrying plate 531, and two insertion holes are provided at both ends of the pressure-carrying plate 531, and first bearings 533 are provided in both the insertion holes and the slots, and the number of the first bearings 533 is five;

[0093] Three sealing plates 532 are disposed in the three slots.

[0094] Preferably, the sealing plate 532 is fixed on the top of the pressure plate 531 by bolts, and after the Sanger sealing plate 532 is fixed by bolts, three of the first bearings 533 will be clamped. At this time, the three sets of symmetrically distributed linkage ends 535 can provide effective rotation-assisting support for the three cake rollers 520, and the three linkage ends 535 arranged in the propulsion outer plate 534 can cooperate with the three cake rollers 520 for stable rotation. At the same time, this assembly method can also facilitate the safe replacement of damaged individual cake rollers 520.

[0095] Two transmission ends 536 are movably mounted at both ends of the propulsion outer plate 534, and a second bearing 537 is disposed inside the transmission end 536;

[0096] Three evenly distributed linkage ends 535 are arranged inside the push outer plate 534, and chains 538 are connected to the two transmission ends 536 and the three linkage ends 535. The linkage ends 535 are composed of a T-shaped column head and a gear sheet, and the inner end of the T-shaped column head is provided with an insertion rod adapted to the insertion hole;

[0097] Two sets of reset components 539 are arranged inside the push outer plate 534;

[0098] The reset assembly 539 includes a limit rod 5391 and a reset spring 5392, wherein the limit rod 5391 is adapted to penetrate the interior of the pressure-bearing plate 531, and one end of the reset spring 5392 is pressed against the inner side of the pressure-bearing plate 531;

[0099] The transmission end head 536 is composed of a rotating wheel adapted to the driving wheel disc 230, a gear ring and an end pipe.

[0100] When in use, when the two 340 are in the initial state, the two outer push plates 534 can stably clamp the evenly distributed multiple linkage ends 535 on both sides of the three dough rollers 520, and at this time the evenly distributed three dough rollers 520 can be in a stable rotation state;

[0101] When the two 340s shrink and push the two outer propulsion plates 534 to extend outward, the evenly distributed multiple linkage ends 535 can be pulled outward. At this time, the multiple cake rollers 520 that are positioned and clamped can lose the driving force, which is convenient for the safe selection of foreign objects and the safe impurity removal operation of workers.

[0102] Embodiment 4:

[0103] Combination Figure 3-Figure 7 As shown, in the above embodiment, the cake mechanism 500 also includes two pull rods 540, a clamp 550 movably mounted on the two pull rods 540, a cushion 560 movably mounted on the middle rod body of the clamp 550, and a support plate 570 movably mounted on the cushion 560.

[0104] Preferably, one end of the pull rod 540 away from the chuck 550 is movably mounted on the chuck at the outer end of the pushing outer plate 534. When the silo 140 is in vibration, the support plate 570 that limits the hydraulic sub-rod in the hydraulic component 190 can adapt to its stable lifting rod and provide a constant driving force for the extension of the two groups of roller body rotation-assisting assemblies 530, thereby ensuring that the free extension of the roller body rotation-assisting assemblies 530 will not be affected during the vibration of the silo 140.

[0105] A slideway is provided in the plate at the top of the support plate 570, and the outer end of the hydraulic sub-rod in the hydraulic component 190 is movably installed in the slideway;

[0106] Anti-slip ends are provided at both ends of the protective roller 510, and insertion holes are provided in the ends of both ends of the cake material roller 520.

[0107] As the hydraulic component 190 operates, the contraction of the internal hydraulic sub-rod will drive the support plate 570 to approach one of the protective rollers 510, and the pad 560 and the clamp 550 installed at the bottom of the support plate 570 will apply a constant thrust to the two pull rods 540. At this time, the two sets of roller body rotation-assisting assemblies 530 can uniformly clamp and release the three evenly distributed cake material rollers 520, so as to facilitate the unified loading and unloading of the three cake material rollers 520, and at the same time facilitate the subsequent inspection and maintenance of the cake material rollers 520.

[0108] The working principle and use process of the present invention: the tobacco processing technology includes the selection of raw materials, pretreatment, moisture regeneration and stem removal, shredding, drying, flavoring, fermentation and aging, rolling and packaging, wherein the tobacco storage cabinet is a pretreatment cabinet with the same specifications to control the temperature and humidity;

[0109] However, currently, tobacco storage cabinets need to use tobacco rollers to separate tobacco before and after. During the tobacco rolling process, the tobacco rollers will break up the bundles or packages. Once there are foreign objects in the tobacco, they need to be manually selected after being screened by the tobacco rollers. However, this operation will have certain risks and may cause safety hazards to workers in serious cases.

[0110] The device is innovative on the tobacco processing line's tobacco roller. When tobacco is delivered along the direction of the hydraulic sub-rod in the hydraulic component 190, as tobacco enters the inner cavity of the silo 140, the motor 220 is running, and its internal transmission shaft drives the driving wheel 230 and the deflection wheel 250 to rotate at high speed, and the impact rod 260 movably mounted on the outer side of the deflection wheel 250, which deviates from the center of the circle, applies a driving force to the bottom of one of the baffle plates 440. At this time, the two baffle plates 440 fixed by the two cross frames 480 can be reciprocated and lifted along the two blocking grooves 160 toward the inside of the silo 140, and the tobacco masterbatch in bundles or packages can be shaken and dispersed.

[0111] The bottom of the silo 140 is provided with densely distributed sieve holes. As the two baffle plates 440 follow the high-frequency vibration inside the two blocking grooves 160, the silo 140 as a whole that receives vibration wave radiation can provide sieving vibration for the bulk material inside. At this time, the impurity particles in the tobacco can be sieved out after the tobacco is loosened.

[0112] The high-hardness debris located directly above the baffle plate 440 and dispersed after being shaken off will be lifted by the baffle plate 440 and exceed the constant height at which the two infrared detectors 300 release the rays;

[0113] At this time, the moment the ray detects a foreign object exceeding the rated height, it will send a command to the system and shut down the motor 220. At the same time, the hydraulic component 190 will also be operated according to the command;

[0114] As the hydraulic sub-rod in the hydraulic component 190 contracts inward, the support plate 570 movably installed on the outer end of the hydraulic sub-rod will drive the cushion 560 and the clamp 550 to move horizontally. At this time, the two pull rods 540 movably connected to the clamp 550 will apply a constant thrust outward to the two groups of roller body rotation-assisting assemblies 530. Finally, the two groups of roller body rotation-assisting assemblies 530 can expand at equal intervals. At this time, the outer push plate 534 will drive the three linkage ends 535 to move outward until the linkage ends 535 are withdrawn from the sockets at both ends of the cake material roller 520. At this time, the three evenly distributed cake material rollers 520 will be in a shutdown state.

[0115] After the two baffle plates 440 separate the material bin 140, the tobacco in the cavity can be conveniently selected by workers to remove foreign objects safely, thereby effectively improving the protection of workers' personal safety;

[0116] According to the type of foreign matter mixed in the tobacco, symmetrically distributed infrared detectors 300 can be set on the top of both ends of the silo 140, and the different foreign matter in the scattered tobacco can be detected by adjusting the height of the rays of two adjacent infrared detectors 300;

[0117] At the same time, the device not only provides protection for the tobacco rollers 520, but also provides a loading platform for rapid maintenance of multiple tobacco rollers 520. When one or two of the tobacco rollers 520 are damaged during use, the chain 538 is then picked out from the linkage end 535 at both ends of the damaged one or two tobacco rollers 520. At this time, the damaged tobacco roller 520 can be deactivated. At this time, the damaged one or two tobacco rollers 520 can be safely and quickly replaced without interfering with the other normal tobacco rollers 520, so as to improve the efficient tobacco processing of bundles or packages by the device.
