[0002] At present, in the existing domestic tobacco silk and reconstituted tobacco production lines, the sack opening and unloading section adopts a completely manual work form of cutting and unloading. This work form has problems such as large labor workload, high labor cost, poor working environment, and production line production efficiency is easily affected by human factors. It limits the further improvement of the production efficiency of the silk production line and the reconstituted tobacco production line, makes it difficult to meet the relevant requirements of the tobacco silk production process specification (YC / T146) and the cigarette process specification, and seriously restricts the improvement of enterprise product quality.

[0003] The above problem is a common problem that needs to be solved by all enterprises in the industry. Both domestic and foreign countries have tried to solve this problem, but none of them have achieved satisfactory results. Other manufacturers are also trying to use other methods to achieve it, but there are currently no feasible solutions and related products.

[0004] With the development of society, enterprises have higher and stricter requirements for production efficiency and sanitary production, which will inevitably force enterprises to transform and upgrade the sack opening and unloading process to meet the requirements of tobacco silk making process specifications and cigarette making process specifications.

[0005] Although there are corresponding devices designed in the prior art to realize the overturning and pouring device for opening or pouring sacks, the materials targeted by the existing overturning and pouring devices are cigarette boxes, which are rigid structures that are not easily deformed, and the actions and fixing methods when pouring are relatively simple, and the scope of application is narrow. The material targeted by the present application is sacks of tobacco stems, which are flexible structures without a fixed shape. Therefore, the actions and fixing methods when pouring are different. In addition, the existing overturning and pouring devices have many structures, complex designs, and great difficulty in maintenance. In short, they are often very inconvenient.

[0029] Among them, each clamping cylinder (51) is connected to the control device.

[0030] As a further improvement of the present invention, the clamping plate (52) is integrally in a square plate-like member or a "Γ" - shaped plate-like member. Among them, a protective layer is further connected to the end face of the non-connected end of the clamping plate (52).

[0031] As a further improvement of the present invention, the clamping component (6) includes:

[0032] A first clamping cylinder (61), and the first clamping cylinder (61) is detachably installed on the connecting plate connection holes on the outer side of the connecting plate (43) through fasteners;

[0035] Among them, the first clamping cylinder (61) and the second clamping cylinder (62) are both connected to the control device.

[0036] As a further improvement of the present invention, the fixed support (1) includes:

[0037] Supports (11), the supports (11) are arranged opposite to each other, and the supports (11) are in a "⊥"-shaped structure as a whole;

[0038] A mounting seat (12), the mounting seat (12) being connected to the top of each support (11) respectively;

[0039] The mounting seat (12) comprises a fixing plate, a bearing connected to a recessed portion in the middle of the fixing plate, and a locking member for locking the bearing to the fixing plate, and two ends of the locking member are detachably connected to the fixing plate by bolts.

[0040] As a further improvement of the above-mentioned present invention, the connecting assembly (2) comprises: a connecting shaft, one end of which is connected to the corresponding side plate of the conveyor belt (7), and the other end of which is rotatably connected to the bearing of the mounting seat (12); and a driven gear, which is connected to the connecting shaft on the side close to the driving mechanism (3);

[0041] The drive mechanism (3) is connected to the fixed support (1) via a bracket, and comprises a drive motor and a transmission gear connected to the drive motor, and a protective shell sleeved on the outside of the transmission gear and the driven gear, wherein the transmission gear is meshed and transmission-connected with the driven gear, wherein the drive motor is connected to the control device.

[0042] The working principle is: before using the overturning and unloading device of the above-mentioned design structure, it only needs to be transported to a designated working position by manual labor or corresponding transport equipment to wait for use.

[0043] When in use, first, the upstream device transports the opened sack (9) containing tobacco stems or fragments to the conveyor belt (7);

[0044] Then, the sack (9) moves under the drive of the conveyor belt (7). When the sack (9) reaches the two photoelectric switches (8), the photoelectric switches (8) detect the sack (9) and immediately send a signal to the control device. After the control device receives the sack arrival signal, the control device sends a stop operation instruction to the conveyor belt (7).

[0045] Then, after the conveyor belt (7) stops, the first clamping cylinder (61) and the second clamping cylinder (62) arranged on the frame (4) are simultaneously lowered, and the clamping blocks (63) connected to the first clamping cylinder (61) and the second clamping cylinder (62) respectively clamp the corresponding positions of the sack (9);

[0046] Finally, after the sack (9) is clamped, the conveyor belt (7) and the components on it are driven by the driving mechanism (3) to rotate around the fixed support (1) as a whole until they are perpendicular to the ground. At this time, the materials in the sack (9) are poured out.

[0047] During the pouring process of the above materials, the flip pouring device has two pouring modes:

[0048] The first material pouring mode is as follows: the first clamping cylinder (61) first lifts up and releases the sack (9), and after a portion of the material is poured out, the first clamping cylinder (61) descends to clamp the sack (9), and then the two second clamping cylinders (62) lift up and release the sack (9), until the material in the sack (9) is completely poured out.

[0049] The second material pouring mode is: the two second clamping cylinders (62) are lifted up and loosened the sack (9) at the same time, and after a part of the material is poured out, the second clamping cylinders (62) are lowered to clamp the sack (9), and then the first clamping cylinder (61) is lifted up and loosened the sack (9), until the material in the sack (9) is completely poured out;

[0050] Both of the above-mentioned two material unloading modes can be realized in the flip unloading device. After the second clamping cylinder (62) and the first clamping cylinder (61) have finished their operations, the conveyor belt (7) and the components on top of it will swing around the fixed support (1) in a small range as a whole under the drive of the driving mechanism (3) to shake out the residual materials.

[0051] After the material is completely poured out, the empty sack (9) needs to be recovered, and the overturning and pouring device can realize two forms of recovering the empty sack (9).

[0052] The first empty sack recycling mode is: when the conveyor belt (7) is vertical to the ground, after the material in the sack (9) has been completely poured out, the second clamping cylinder (62) and the first clamping cylinder (61) are all lifted to release the sack (9), and the empty sack (9) falls to the work station below for collecting the empty sack (9);

[0053] The second empty sack recycling mode is: when the conveyor belt (7) is vertical to the ground, the material in the sack (9) has been completely poured out, and then the conveyor belt (7) and its upper parts will be driven by the driving mechanism (3) to revolve around the fixed support (1) to restore to a state horizontal to the ground, and when the conveyor belt (7) starts to transport the sacks (9) to be poured to the pouring station, the empty sacks (9) will also be synchronously sent to the downstream empty sack collection station.

[0054] Compared with the prior art, the present invention has the following beneficial effects:

[0055] 1. The present invention has wide applicability and can be used in any tobacco shred and reconstituted tobacco production line, and can be used in conjunction with other related equipment;

[0056] 2. The present invention is highly flexible and can be matched with any current tobacco thread and reconstituted tobacco leaf production line, meeting the requirements of sack dumping technology and ensuring the production requirements of full process automation;

[0057] 3. The present invention is safe, reliable and efficient, and can improve production efficiency, solve pollution problems, reduce production pollution, and meet the relevant needs of enterprises to reduce costs and increase efficiency;

[0058] 4. The present invention realizes the automation upgrade of the sack turning and unloading process, and through the fully automated unloading form, improves the production efficiency, improves the production quality, and reduces the labor intensity;

[0059] 5. The material unloading mechanism of the present invention is fully automated, which simplifies the production process and avoids production accidents that may occur during unloading. It achieves the application of fewer mechanisms under the premise of more complex actions and has better maintainability. BRIEF DESCRIPTION OF THE DRAWINGS

[0118] In summary, a more specific embodiment of the present invention is:

[0119] Before using the overturning and unloading device of the above-mentioned design structure, it only needs to be transported to a designated working position by manual labor or corresponding transport equipment to wait for use.

[0120] When in use, first, the upstream device conveys the opened sack 9 loaded with tobacco stems or fragments to the conveyor belt 7;

[0121] Then, the sack 9 moves under the drive of the conveyor belt 7. When the sack 9 reaches the two photoelectric switches 8, the photoelectric switches 8 detect the sack 9 and immediately send a signal to the control device. After the control device receives the sack arrival signal, the control device sends a stop command to the conveyor belt 7.

[0122] Then, after the conveyor belt 7 stops, the first clamping cylinder 61 and the second clamping cylinder 62 arranged on the frame 4 are simultaneously lowered, and the clamping blocks 63 connected to the first clamping cylinder 61 and the second clamping cylinder 62 clamp the corresponding positions of the sack 9 respectively;

[0123] Finally, after the sack 9 is clamped, the conveyor belt 7 and its upper components are driven by the driving mechanism 3 to rotate as a whole around the fixed support 1 until they are perpendicular to the ground. At this time, the materials in the sack 9 are immediately poured out.

[0124] During the pouring process of the above materials, the flip pouring device has two pouring modes:

[0125] The first material pouring mode is: the first clamping cylinder 61 first lifts up and loosens the sack 9, and after a part of the material is poured out, the first clamping cylinder 61 descends to clamp the sack 9, and then the two second clamping cylinders 62 lift up and loosen the sack 9 until the material in the sack 9 is completely poured out.

[0126] The second material pouring mode is: the two second clamping cylinders 62 are lifted up and loosened the sack 9 at the same time, and after a part of the material is poured out, the second clamping cylinders 62 are lowered to clamp the sack 9, and then the first clamping cylinder 61 is lifted up and loosened the sack 9 until the material in the sack 9 is completely poured out;

[0127] The above two material unloading modes can be realized in the flip unloading device. After the second clamping cylinder 62 and the first clamping cylinder 61 are operated, the conveyor belt 7 and the components on it will swing around the fixed support 1 in a small range as a whole under the drive of the driving mechanism 3 to shake out the residual materials.

[0128] After the material is completely poured out, the empty sack 9 needs to be recovered, and the overturning and pouring device can realize two forms of recovering the empty sack 9.

[0129] The first empty sack recycling mode is: when the conveyor belt 7 is vertical to the ground, after the materials in the sack 9 have been completely poured out, the second clamping cylinder 62 and the first clamping cylinder 61 are all lifted to release the sack 9, and the empty sack 9 falls to the station below for collecting the empty sack 9;

[0130] The second empty sack recycling mode is: when the conveyor belt 7 is vertical to the ground, the material in the sack 9 has been completely poured out, and then the conveyor belt 7 and its upper components will be driven by the driving mechanism 3 to recover to a state horizontal to the ground around the fixed support 1, and when the conveyor belt 7 starts to transport the sacks 9 to be unloaded to the unloading station, the empty sacks 9 will also be synchronously sent to the downstream empty sack collection station.
