Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco leaf production transmission, and particularly relates to a transmission structure for preventing tobacco leaves from being stuck. Background Art

[0002] Tobacco is an important cash crop, occupying an important economic position among the crops in China. It is an important agricultural product for increasing farmers' income. The total tax revenue and profit of the tobacco industry reach 1 trillion yuan. The total production value of the tobacco-related industries accounts for about 2.8% of the domestic GDP, making an important contribution to China's economic development.

[0003] In tobacco leaf production, the tobacco leaves need to be sorted first. The tobacco leaves are transmitted through a transmission structure and automatically sorted, and the tobacco leaves are sorted according to standards. However, in the existing sorting structure, a rod body is used to push the tobacco leaves to move on several plate bodies. When it is detected that the tobacco leaves to be sorted out are needed, the motor drives the plate body to rotate downward, that is, one end of the plate body is controlled to rotate downward. Then the tobacco leaves continue to move along the rotating plate body until they fall into the sorting bin. However, since both side edges of the plate body structure are vertical structures, after rotating a certain angle, a large gap appears at the joint of two adjacent plate bodies (such as Figure 4 the circled position in), there is originally a certain gap at the joint of the plate body structure, and after one side rotates, the gap will increase. Therefore, when the tobacco leaves pass through this position, they are extremely likely to get stuck in the gap, affecting the falling of the tobacco leaves into the sorting bin. Specifically, see Figure 4 (where the dotted line part is the plate body structure rotating downward). This method is likely to cause the tobacco leaves to get stuck in the gap of the transmission structure. Therefore, a transmission structure for preventing tobacco leaves from being stuck is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the problem that tobacco leaves are easily stuck in the gap in the existing sorting and transmission structure, and provide a transmission structure for preventing tobacco leaves from being stuck. By means of a diversion plate and a partition plate, the connecting side of the diversion plate and the partition plate is set as an arc structure. The arc structure is connected to the partition plate as an extension end. The arc structure, as a compensation design, eliminates the gap between the diversion plate and the partition plate, so that after the diversion plate rotates, the partition plate and the diversion plate are still connected, eliminating the gap. And an elastic rope is used to press the tobacco leaves from above to prevent the tobacco leaves from fluttering during the transmission process, reducing the risk of being stuck.

[0005] To achieve the above purpose, the utility model provides a transmission structure for preventing tobacco leaves from being stuck, including an elastic rope and a support plate mechanism. The elastic ropes are uniformly distributed on the support plate mechanism. Several groups of the support plate mechanisms are uniformly distributed. Brackets are fixedly connected to both sides of the support plate mechanism. The elastic ropes are uniformly distributed between the brackets.

[0006] Preferably, the support plate mechanism includes a limit component, a drainage plate, a flap, and a partition. The limit component is divided into two parts and is arranged on the side of the bracket. The flap is arranged between the limit components. The partitions are evenly distributed on the flap. The drainage plate is rotatably arranged between the limit components. One side of the drainage plate is close to the partition. Vertically arranged plate structures are evenly distributed on the top of the drainage plate. A groove structure is arranged on the side of the plate structure close to the partition. The groove structure is movably sleeved on one side of the partition. The groove structure and the partition are arranged in one-to-one correspondence. The side of the plate structure close to the partition is an arc structure.

[0007] Preferably, the limit component includes a fixing plate, an induction rod, a cam, a rotating shaft, a fixing frame, and a driving motor. The fixing frame and the fixing plate are respectively installed on the side surfaces of the two brackets. The driving motor is fixedly arranged on the fixing frame. The two ends of the rotating shaft respectively penetrate through the fixing plate and the fixing frame in a rotating manner. One end of the rotating shaft is fixedly connected to the driving motor. The cam is fixedly sleeved on the rotating shaft. The induction rod is arranged on the fixing plate.

[0008] Preferably, the lower end of the induction rod is slidably connected to the cam.

[0009] Preferably, the drainage plate is fixedly sleeved on the rotating shaft.

[0010] The beneficial effects of the present utility model are as follows:

[0011] In the present utility model, tobacco leaves are supported by the sorting support plate. Through the drainage plate and the partition, the connecting side of the drainage plate and the partition is set as an arc structure. The arc structure is used as an extension end to connect to the partition. The arc structure is used as a compensation design to eliminate the gap between the drainage plate and the partition. After the drainage plate rotates, the partition and the drainage plate are still connected, eliminating the gap. And elastic ropes are used to press the tobacco leaves from above to prevent the tobacco leaves from fluttering during the transmission process, reducing the risk of being stuck, and solving the problem that tobacco leaves are easily stuck in the gap in the sorting and transmission structure in the background technology.

[0019] This embodiment provides a transmission structure for preventing tobacco leaves from being stuck, including an elastic rope 1 and a support plate mechanism 2. The elastic ropes 1 are evenly distributed on the support plate mechanism 2, and several groups of support plate mechanisms 2 are evenly distributed. Bracket 3 is fixedly connected to both sides of the support plate mechanism 2, and the elastic ropes 1 are evenly distributed between the brackets 3.

[0020] In one embodiment, specifically, the support plate mechanism 2 includes a limit component 4, a drainage plate 5, a flap 6 and a partition 7. The limit component 4 is divided into two parts. The limit component 4 is arranged on the side of the bracket 3. The flap 6 is arranged between the limit components 4. The partitions 7 are evenly distributed on the flap 6. The drainage plate 5 is rotatably arranged between the limit components 4. One side of the drainage plate 5 is close to the partition 7. Vertically arranged plate structures are evenly distributed on the top of the drainage plate 5. A groove structure is arranged on the side of the plate structure close to the partition 7. The groove structure is movably sleeved on one side of the partition 7. The groove structure and the partition 7 are arranged in one-to-one correspondence.

[0021] In one embodiment, specifically, the limit assembly 4 includes a fixed plate 8, a sensing rod 9, a cam 10, a rotating shaft 11, a fixed bracket 12, and a driving motor 13. The fixed bracket 12 and the fixed plate 8 are respectively installed on the side surfaces of the two side brackets 3. The driving motor 13 is fixedly arranged on the fixed bracket 12.

[0024] The working process of the tobacco leaf anti-jamming conveying structure in this embodiment is as follows: The tobacco leaves are placed between the elastic rope 1 and the support plate mechanism 2. The tobacco leaves move on the support plate mechanism 2. When corresponding tobacco leaves need to be sorted out, the driving motor 13 drives the rotating shaft 11 to rotate, and at the same time controls the drainage plate 5 to rotate, that is, the drainage plate 5 rotates downward with the rotating shaft 11 as the rotation center. At this time, the arc structure rotates together. The arc structure always remains in contact with the partition plate 7. The arc structure is a compensation design, eliminating the gap and preventing the tobacco leaves from getting stuck in the gap.
