In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] Combine the following Figure 1 to Figure 2 The utility model describes a tobacco stem pressing device for preventing blocking material.

[0030] like Figure 1 to Figure 2 As shown, a tobacco stem pressing device for preventing material blocking comprises: a mounting frame 1, a first pressing roller 2, a second pressing roller 3, a first driving assembly 4, a material blocking detector 5 and a control module; the first pressing roller 2 and the second pressing roller 3 are both rotatably arranged on the mounting frame 1, the first pressing roller 2 and the second pressing roller 3 are parallel to each other, the second pressing roller 3 can slide relative to the mounting frame 1, the first driving assembly 4 is connected to the second pressing roller 3, and the first driving assembly 4 is used to drive the second pressing roller 3 to approach or move away from the first pressing roller 2; the material blocking detector 5 is arranged between the first pressing roller 2 and the second pressing roller 3, and the material blocking detector 5 and the first driving assembly 4 are both connected to the control module.

[0031] Specifically, both ends of the first pressing roller 2 and the second pressing roller 3 are rotatably connected with mounting seats, the mounting seat corresponding to the first pressing roller 2 is connected to the mounting frame 1, and the mounting seat corresponding to the second pressing roller 3 is slidably connected to the mounting frame 1. The first pressing roller 2 and the second pressing roller 3 are respectively connected with motors to drive the first pressing roller 2 and the second pressing roller 3 to rotate, thereby completing the pressing process. The control module can control the first driving component 4 to drive the second pressing roller 3 to approach or move away from the first pressing roller 2, thereby adjusting the distance between the first pressing roller 2 and the second pressing roller 3. The blocking detection component 5 is used to detect whether there is a blockage between the first pressing roller 2 and the second pressing roller 3. When the blocking detection component 5 detects that a blockage occurs, the control module obtains the blocking information, and then controls the first driving component 4 to drive the second pressing roller 3 away from the first pressing roller 2, so that the blocked material falls naturally under the action of gravity, until the blocking detection component 5 detects that there is no blockage, the control module controls the first driving component 4 to drive the second pressing roller 3 to reset, thereby continuing the pressing work.

[0032] The tobacco stem pressing device for preventing material blockage of the present invention drives the second pressing roller 3 to approach or move away from the first pressing roller 2 by the first driving component 4, so as to adjust the distance between the first pressing roller 2 and the second pressing roller 3 to an optimal value, thereby improving the stem pressing effect. It also detects whether material blockage occurs between the first pressing roller 2 and the second pressing roller 3 by the material blockage detection component 5, and drives the second pressing roller 3 away from the first pressing roller 2 by the first driving component 4 when material blockage occurs, thereby increasing the distance between the first pressing roller 2 and the second pressing roller 3, so that the blocked material is released and naturally falls under the action of gravity, so as to continue the stem pressing work, thereby effectively solving the problem of material blockage occurring in the tobacco stem pressing process in the prior art.

[0033] In some embodiments, the first driving assembly 4 may be a component of a pneumatic cylinder or a hydraulic cylinder, and the first driving assembly 4 is connected to a mounting seat corresponding to the second pressing roller 3 .

[0034] like Figure 1 to Figure 2 As shown, in some embodiments, the tobacco stem pressing device for preventing material blocking also includes a discharge component 6, a flap 7 and a second drive component 8. The discharge component 6 includes a frame 61 and a discharge surface 62 connected to each other. The discharge surface 62 is inclined, and a discharge port is provided at the higher end of the discharge surface 62. A flap 7 is hinged on one side of the discharge port. The flap 7 is located below the area between the first pressing roller 2 and the second pressing roller 3. The flap 7 is connected to the second drive component 8, and the second drive component 8 is connected to the control module. The second drive component 8 is used to drive the flap 7 to flip to open or close the discharge port.

[0035] Specifically, a discharge pipe 63 is connected to the lower end of the discharge port. During the process of pressing the stems, the flap 7 closes the discharge port. At this time, the flap 7 is coplanar with the discharge surface 62. The material after the stem pressing falls on the flap 7, and the discharge surface 62 is inclined. Therefore, the material falling on the flap 7 can slide to the discharge surface 62, and finally be discharged from the lower end of the discharge surface 62. When a material blockage occurs, the control module controls the second drive component 8 to drive the flap 7 to flip, thereby opening the discharge port, and the first drive component 4 drives the second pressing roller 3 away from the first pressing roller 2, so that the blocked unpressed or incompletely pressed material falls into the discharge pipe 63 for collection and re-pressing. Optionally, the second drive component 8 may include a motor and a rotating shaft, and the motor is connected to one side of the flap 7 through the rotating shaft, and the flap 7 is driven to flip by the motor.

[0036] like Figure 1 to Figure 2 As shown, in some embodiments, the discharge assembly 6 further includes a vibrating member 64 , and one of the frame 61 and the discharge surface 62 is connected to the vibrating member 64 , and the vibrating member 64 is used to drive the discharge surface 62 to vibrate.

[0037] Specifically, the vibrating member 64 can be a component such as a vibration motor, which vibrates the discharge surface 62 so that the material on the discharge surface 62 slides down along the discharge surface 62, so that even if the inclination angle of the discharge surface 62 is small, the material on the discharge surface 62 can still move, which helps to save the setting space of the discharge component 6.

[0038] like Figure 1 to Figure 2 As shown, in some embodiments, a plurality of sieve holes are evenly distributed on the discharge surface 62 , and the discharge surface 62 separates the frame 61 into an upper layer and a lower layer, and a lower end of the lower layer is connected to a slag discharge port 65 .

[0039] Specifically, the frame 61 is in the shape of a box with an opening at the upper end, and the frame 61 and the discharge surface 62 have the same inclination angle. During the stem pressing process, the material after the stem pressing falls on the flap 7, and there are no sieve holes on the flap 7. Therefore, the material after the stem pressing will not enter the discharge pipe 63, but will only slide to the discharge surface 62. Under the vibration of the vibrating member 64, impurities and debris in the material will pass through the sieve holes of the discharge surface 62 and enter the lower layer, and finally be discharged from the slag discharge port 65, and the material after the slag is screened out will be discharged from the end of the upper layer with a lower height.

[0040] In some embodiments, the material blockage detection element 5 is a through-beam detection photoelectric sensor.

[0041] Specifically, the material blockage detection component 5 can emit infrared light in a direction parallel to the first pressure roller 2 and the second pressure roller 3. When the infrared light is continuously blocked for a preset time, it is determined that a material blockage has occurred. The preset time can be specifically five seconds.

[0042] like Figure 1 As shown, in some embodiments, the tobacco stem pressing device for preventing material blocking also includes a cover body 9, the first pressing roller 2, the second pressing roller 3 and the material blocking detection component 5 are all located in the cover body 9, the upper and lower ends of the cover body 9 are both open, and a cover plate is provided at the upper opening of the cover body 9, the cover plate is hinged to the upper end of the cover body 9, and a material guide pipe can be provided at the lower end of the cover body 9 to guide the material to the flap 7, so that the position of the discharge assembly 6 is more flexible.

[0043] In some embodiments, the cover body 9 is provided with an openable and closable observation window, and the observation window is at least partially adjacent to the blockage detection member 5 .

[0044] Specifically, the observation window is a transparent glass window, and one side of the observation window is hinged to the cover body 9. The observation window is adjacent to the material blocking detection member 5 so that workers can observe the compression situation, and the observation window can be opened so that workers can clean the material blocking detection member 5 and the inner side of the observation window to maintain the transparency of the observation window and ensure that the material blocking detection member 5 works normally.

[0045] like Figure 1As shown, in some embodiments, the tobacco stem pressing device for preventing material blocking also includes a material guide 91, which is arranged inside the cover body 9 and connected to the cover body 9, and is used to guide the tobacco to between the first pressing roller 2 and the second pressing roller 3.

[0046] Specifically, the material guide member 91 may be a plurality of guide plates arranged obliquely, wherein the lower end of the guide plate points to the area between the first pressing roller 2 and the second pressing roller 3.

[0047] In some embodiments, the tobacco stem pressing device for preventing blocking material further includes an alarm, which is connected to a control module. The control module is used to control the alarm to sound or stop the alarm, and is also used to record the number of alarms of the alarm.

[0048] Specifically, the alarm is a sound alarm and / or a light alarm. When a material blockage occurs, the control module controls the alarm to remind the worker by sound or by lighting an alarm light. When the alarm sounds for a long time, it indicates that the tobacco stem pressing device for preventing material blockage may not be able to automatically handle the situation, so that the worker can handle it. At the same time, the control module will also record the number of times the material blockage occurs within a certain period of time so that the worker can query the alarm record. When the material blockage occurs too frequently, it is considered whether it is due to the unreasonable spacing between the first pressing roller 2 and the second pressing roller 3, etc., so that the worker can troubleshoot the problem.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
