[0002] In the vacuum rehumidification process of the tobacco industry, the slit tobacco blocks need to be loaded into multiple vacuum material boxes before entering the vacuum rehumidification equipment for processing. Therefore, after one box of tobacco blocks is filled, the conveyor belt stops, the filled vacuum box is moved away, and the conveyor belt starts running again after the next box is in place, and the tobacco blocks are loaded into the next empty box.

[0003] However, during the process of filling a box of cigarette blocks and stopping the conveyor belt, the box full of cigarette blocks has been moved away, and before the next box of cigarette blocks is in place, the cigarette blocks on the conveyor belt will fall off due to inertia, which will cause material waste. At the same time, the cigarette blocks may fall into the gaps of the equipment and cause malfunctions.

[0004] Therefore, there is an urgent need for a tobacco packing blocking device to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0039] like Figures 1-2 As shown, in this embodiment, the tobacco packing blocking device includes a frame, a baffle 3, and a telescopic drive source 4. The frame includes a base 1 and a fixed frame 2. The base 1 is disposed on the side guard plates 200 of the conveyor belt 100, and the fixed frame 2 is disposed on the base 1. The baffle 3 is located at the discharge port of the conveyor belt 100 and is rotatably mounted on the fixed frame 2. The fixed end of the telescopic drive source 4 is mounted on the fixed frame 2, and the telescopic end of the telescopic drive source 4 is rotatably connected to the baffle 3. The baffle 3 can rotate relative to the fixed frame 2 under the action of the telescopic drive source 4, so that the baffle 3 can block or discharge the material on the conveyor belt 100.

[0040] For example, the material is tobacco blocks. In the tobacco workshop, the vacuum rehumidification process requires transporting the slit tobacco blocks via conveyor belt 100 and loading them into multiple material boxes. The guard plates 200 on both sides of the conveyor belt 100 can protect against and prevent tobacco blocks from falling. Material boxes are placed below the discharge port of the conveyor belt 100. When a material box is full of tobacco blocks, the conveyor belt 100 stops, and the full material box is moved away until the next empty material box is in place. Then the conveyor belt 100 starts running again, continuing to fill the material box with the transported tobacco blocks, and the cycle repeats.

[0041] Two crossbars of the base 1 are respectively installed on the guard plates 200 on both sides of the conveyor belt 100. The material box is located below the base 1, and the opening of the material box is aligned with the discharge port of the conveyor belt 100. The fixing frame 2 is fixedly connected to the base 1 and is located in front of the discharge port of the conveyor belt 100.

[0042] Along the width direction of the conveyor belt 100, the two sides of the baffle 3 are rotatably connected to the left and right sides of the fixed frame 2, respectively. The width of the baffle 3 should be equal to or greater than the width of the conveyor belt 100, so that it can freely rotate between the guard plates 200 on both sides of the conveyor belt 100, and can also ensure that all smoke blocks on the conveyor belt 100 can be blocked by the baffle 3. Optionally, the two sides of the baffle 3 are provided with limiting plates, which can play a role in limiting and preventing leakage, preventing smoke blocks on the conveyor belt 100 from gradually accumulating on the surface of the baffle 3 and falling from the two sides of the baffle 3 to the ground or the conveying device, causing material waste.

[0043] The telescopic drive source 4 is configured as a device that drives the piston rod to extend and retract using a cylinder or hydraulic cylinder, specifically a telescopic cylinder or a telescopic hydraulic cylinder. One end of the telescopic drive source 4 is installed in the middle position of the fixed frame 2, and the other end of the telescopic drive source 4 is rotatably connected to the top middle position of the baffle 3 via a rotating shaft. The telescopic drive source 4 can be turned on or off at regular intervals by a timer. That is, under the action of the timer, the telescopic drive source 4 is turned on at regular intervals, and the telescopic drive source 4 can extend and drive the baffle 3 to flip and separate from the conveyor belt 100, so that the material can be boxed. After a certain period of time, the timer turns on the telescopic drive source 4 at regular intervals, and the telescopic drive source 4 can retract and drive the baffle 3 to flip in the opposite direction and contact the conveyor belt 100, so that the baffle 3 blocks the material from being unloaded, and the cycle repeats. Alternatively, the operator can turn it on and off using the control buttons of a remote control. After the operator visually determines that the material box is full, they can control the telescopic drive source 4 through the buttons on the controller. Under the driving action of the telescopic drive source 4, the baffle 3 can flip back and forth relative to the fixed frame 2, so that the bottom edge of the baffle 3 separates from or contacts the conveyor belt 100. When the baffle 3 flips to contact the surface of the conveyor belt 100, the baffle 3 blocks the smoke material on the conveyor belt 100, preventing the smoke material from falling due to inertia. When the baffle 3 flips to separate from the surface of the conveyor belt 100, the smoke material on the conveyor belt 100 falls into the material box for packing under the drive of the conveyor belt 100.

[0044] The working principle of this tobacco packing blocking device is as follows: When an empty material box is located below the discharge port of conveyor belt 100, the telescopic drive source 4 opens, the telescopic end of the telescopic drive source 4 extends and drives the baffle 3 to flip relative to the fixed frame 2, causing the baffle 3 to separate from the conveyor belt 100. At the same time, the conveyor belt 100 runs, and the tobacco lumps on the conveyor belt 100 fall into the material box. When the material box is visually full, the conveyor belt 100 stops. Simultaneously, the telescopic end of the telescopic drive source 4 retracts and drives the baffle 3 to flip in the opposite direction relative to the fixed frame 2, causing the baffle 3 to contact the conveyor belt 100. The baffle 3 can prevent the tobacco lumps on the conveyor belt 100 from falling, avoiding pollution of the surrounding environment due to inertia, and preventing tobacco lumps from falling into the gaps of the equipment and causing malfunctions. The telescopic drive source 4 and conveyor belt 100 are restarted when the next empty material box is in place.

[0045] Furthermore, referring to Figures 1-2 The tobacco packing blocking device also includes a position sensor, which is mounted on the frame and electrically connected to the telescopic drive source 4. The position sensor is used to detect whether the material box is located below the discharge port of the conveyor belt 100.

[0046] The position sensor includes a position detector and a control circuit board electrically connected to the position detector. The control circuit board is also electrically connected to the telescopic drive source 4. When the position detector detects that the material box below the discharge port of the conveyor belt 100 is in place and empty, the position detector sends a high-level signal to the control circuit board. The control circuit board then controls the telescopic drive source 4 to extend, thereby driving the baffle 3 to flip relative to the fixed frame 2, separating the baffle 3 from the conveyor belt 100 and facilitating the dropping of the tobacco material on the conveyor belt 100 into the material box for packing. When the position detector detects that the material box below the discharge port of the conveyor belt 100 is full, the position detector sends a low-level signal to the control circuit board. The control circuit board then controls the telescopic drive source 4 to retract, thereby driving the baffle 3 to flip in the opposite direction relative to the fixed frame 2, bringing the baffle 3 into contact with the conveyor belt 100. The baffle 3 prevents the tobacco material on the conveyor belt 100 from falling off. The automatic control of the baffle 3's flipping by the position sensor results in a high degree of automation, requiring no manual operation.

[0047] Furthermore, referring to Figures 1-2 The tobacco packing blocking device also includes a scraper 5, which is disposed on the baffle 3. When the baffle 3 blocks the material on the conveyor belt 100, the scraper 5 can abut against the conveyor belt 100.

[0048] The scraper 5 is made of rubber and is installed at the bottom of the baffle 3 by multiple bolts. It is detachable and easy to replace. When the material box is full, the telescopic drive source 4 retracts and drives the baffle 3 to flip in the opposite direction relative to the fixed frame 2, so that the scraper 5 of the baffle 3 comes into contact with the conveyor belt 100. The baffle 3 can prevent the smoke block material from falling, and at the same time, the scraper 5 can prevent the smoke ash or smoke residue on the surface of the conveyor belt 100 from falling, thus avoiding pollution of the surrounding environment.

[0049] Furthermore, referring to Figures 1-2 The fixing frame 2 includes a support base 21 and two fixing plates 22. The support base 21 is fixedly connected to the base 1, and the two fixing plates 22 are spaced apart on the support base 21. The two fixing plates 22 are rotatably connected to both sides of the baffle 3, and the telescopic drive source 4 is located between the two fixing plates 22. The tobacco packing blocking device also includes a spherical bearing 6. The baffle 3 has a protruding fixing base 31, and the fixing plates 22 are rotatably connected to the fixing base 31 through the spherical bearing 6.

[0050] The support base 21 and the base 1 are integrally formed. Two fixing plates 22 are spaced apart along the width direction of the conveyor belt 100, and the fixing plates 22 are integrally formed with the support base 21. The connection between the two fixing plates 22 and the two sides of the baffle 3 is the first position and the second position, respectively. The connection between the telescopic end of the telescopic drive source 4 and the baffle 3 is the third position. The third position is not on the same straight line as the first and second positions, that is, the end of the telescopic drive source 4 can rotate relative to the baffle 3. At the same time, it can have a certain degree of freedom with the baffle 3, so that the telescopic end of the telescopic drive source 4 has room to avoid the flipping of the baffle 3 during the telescopic process, and avoids interference between the telescopic drive source 4 and the baffle 3, which would affect the flipping. The two fixing plates 22 have connecting holes, and the fixing base 31 has rotating holes. The spherical bearing 6 is rotatably inserted through the connecting holes and the rotating holes. Under the action of the spherical bearing 6, the baffle 3 can flip relative to the fixing base 31.

[0051] Furthermore, referring to Figures 1-2 The fixed frame 2 also includes a mounting base 23, which is fixedly connected to the support base 21 and is rotatably connected to the fixed end of the telescopic drive source 4.

[0052] Mounting base 23 is fixedly mounted to the middle position of support base 21 by several bolts. The fixed end of telescopic drive source 4 is rotatably connected to mounting base 23 through a rotating shaft. During the flipping process, the baffle 3 ensures that the telescopic drive source 4 can rotate relative to mounting base 23 and has a certain degree of freedom, so as to avoid the telescopic drive source 4 getting stuck and affecting the flipping of baffle 3.

[0053] Furthermore, referring to Figures 1-2 The tobacco packing blocking device also includes a first reinforcing tube 7 and a second reinforcing tube 8. The first reinforcing tube 7 is fixedly connected to the baffle 3 and extends along the length of the baffle 3. The second reinforcing tube 8 is fixedly connected to the baffle 3 and is perpendicular to the first reinforcing tube 7.

[0054] The first reinforcing tube 7 and the second reinforcing tube 8 are fixedly installed on the end face of the baffle 3 by welding or gluing, which can strengthen the overall structure of the baffle 3.

[0055] Furthermore, referring to Figures 1-2 The tobacco packing blocking device also includes a connector 9. The base 1 has a connection hole, and the side guard plates 200 of the conveyor belt 100 have mounting holes. The connector 9 passes through the connection hole and is connected to the mounting hole.

[0056] The connector 9 is a fastening bolt. The two crossbars of the base 1 are located on the guard plates 200 on both sides of the conveyor belt 100, and the base 1 is located at the discharge port of the conveyor belt 100. The base 1 is fixedly installed at the end discharge port of the conveyor belt 100 by the connector 9, ensuring that the tobacco packing blocking device can block or discharge the tobacco material on the conveyor belt 100. Similarly, the base 1 is detachably connected to the conveyor belt 100, allowing direct use of conveyor belts 100 on other production lines, thus reducing costs.
