Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette production, and particularly relates to a stem rolling machine. Background Technique

[0002] A stem rolling machine is a device used to press tobacco stems to a certain thickness. Stem rolling mainly changes the shape of tobacco stems and flattens the softened and plastically deformable tobacco stems. Its function is to create a favorable technological condition for the subsequent cutting process to obtain good cutting quality.

[0003] Generally, to prevent blockage between two rolling mills due to excessive materials, opposed detection photoelectric tubes are arranged on both sides of the two rolling mills. When materials are blocked between the two rolling mills, the materials accumulate and block the detection photoelectric tubes, and the system issues a material blockage alarm. At this time, the system controls the two rolling mills to move away from each other, and the accumulated materials between the two rolling mills can fall and be discharged. Before this, to prevent unprocessed tobacco stems from being mixed with processed tobacco stems, it is necessary to manually remove the processed tobacco stems in advance, then control the two rolling mills to move away from each other, and then manually remove the unprocessed tobacco stems discharged for re - extrusion. It is necessary to disassemble and assemble the machine, which burdens the maintenance personnel heavily, requires a long maintenance time and affects the cigarette production efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a stem rolling machine, which is used to solve the problems that the existing stem rolling machine has a heavy maintenance burden and long required time when material blockage occurs, affecting production efficiency.

[0005] To achieve the above - mentioned technical purpose, the technical scheme adopted by the utility model is as follows:

[0006] A stem rolling machine includes an installation box, a roller assembly and a driving assembly. The roller assembly includes a first roller and a second roller rotatably arranged in the installation box. An extrusion channel is formed between the first roller and the second roller. An actuating mechanism for driving the first roller and the second roller to rotate is arranged outside the installation box. The driving assembly is used to drive the first roller to slide away from the second roller and discharge the accumulated materials. A material receiving assembly is arranged at the bottom of the extrusion channel, and the material receiving assembly is used to guide and collect the accumulated materials when discharging the accumulated materials.

[0007] In this application, when a phenomenon of material accumulation occurs above the first roller and the second roller, the material receiving assembly can automatically collect the dropped unextruded tobacco stems during the process of the first roller moving away from the second roller, so that they are not mixed with the extruded tobacco stems, without disassembling and assembling the mechanical equipment, and reducing the maintenance cycle.

[0008] Further preferably, the driving mechanism includes a first motor, a second motor and a mounting seat. The second motor is mounted on the mounting box and is used to drive the second pressure roller to rotate. Mounting shafts are provided at both ends of the first pressure roller. Sliding grooves are provided on the mounting box corresponding to the mounting shafts. Sliders are arranged in the sliding grooves. After passing through the sliders, the mounting shafts are drivingly connected to the first motor. The mounting seat is slidably arranged on the mounting box.

[0009] Further preferably, the driving assembly includes a hydraulic rod, and the output end of the hydraulic rod is fixedly connected to the mounting seat.

[0010] Further preferably, a spring is arranged between the hydraulic rod and the mounting shaft.

[0011] In this application, when the feeding of tobacco stems is uneven, resulting in different pressures at both ends between the two rollers, it is offset by the compression force of the spring, making the tobacco stem pressing process stable and noiseless.

[0012] Further preferably, the material receiving assembly includes a plurality of guide plates rotatably mounted below the extrusion channel and a motor for driving the guide plates to rotate. The guide plates can form a guiding channel under the drive of a rotating member. An opening is provided on the mounting box corresponding to the end of the guiding channel.

[0013] In this application, when not in the material guiding working condition, the guide plates are arranged vertically in a stepped shape inside the mounting box. At this time, the first pressure roller and the second pressure roller normally extrude the tobacco stems, and the tobacco stems after extrusion can normally fall between the guide plates; when a material accumulation phenomenon occurs above the first pressure roller and the second pressure roller, they rotate under the drive of the motor until all the guide plates are connected end to end to form a guiding channel. At this time, the unextruded tobacco stems can fall onto the guiding channel and be discharged from the opening.

[0014] Further preferably, the material receiving assembly includes a guide plate rotatably mounted below the extrusion channel and a rotating member for driving the guide plate to rotate. The guide plate is a side plate of the mounting box, and the bottom end of the guide plate is hinged to the mounting box.

[0015] In this application, a part of the side plate of the mounting box is used as the guide plate. During use, the side plate is rotated to receive and guide the falling tobacco stems, and there is no need to additionally open a discharge port on the mounting box.

[0016] The utility model adopting the above technical solution has the following advantages:

[0017] 1. In this application, when a material accumulation phenomenon occurs above the first pressure roller and the second pressure roller, the material receiving assembly can automatically collect the unextruded tobacco stems that fall during the process of the first pressure roller moving away from the second pressure roller, so that they are not mixed with the extruded tobacco stems, without the need to disassemble and assemble the mechanical equipment, and the maintenance period is reduced.

[0018] 2. In this application, if the tobacco stem feeding is uneven, resulting in different pressures at both ends between the two rollers, the compression force of the spring is used to offset it, making the tobacco stem pressing process stable and noiseless.

[0019] 3. In this application, a part of the side plate of the installation box is used as a guide plate. During use, the side plate is rotated to receive and guide the falling tobacco stems, and there is no need to additionally open a discharge port on the installation box.

The pressing roller assembly 2 includes a first pressing roller 21 and a second pressing roller 22 that are rotatably arranged in the installation box, and an extrusion channel is formed between the first pressing roller 21 and the second pressing roller 22. A driving mechanism for driving the first pressing roller 21 and the second pressing roller 22 to rotate is arranged outside the installation box 1. The driving assembly 3 is used to drive the first pressing roller 21 to slide away from the second pressing roller 22 and discharge the pile. A material receiving assembly 4 is arranged at the bottom of the extrusion channel. The material receiving assembly 4 is used to guide and collect the pile when discharging the pile. In this way, when the pile phenomenon occurs above the pressing roller, the material receiving assembly 4 can automatically collect the fallen un-pressed tobacco stems during the process of the first pressing roller 21 moving away from the second pressing roller 22, so that they are not mixed with the squeezed tobacco stems, and there is no need to disassemble and assemble the mechanical equipment, thereby reducing the maintenance cycle.

[0032] Specifically, the driving mechanism includes a first motor 23, a second motor 24 and a mounting seat 25. The second motor 24 is mounted on the mounting box 1 and is used to drive the second pressure roller 22 to rotate. The first pressure roller 21 is provided with mounting shafts 211 at both ends. The mounting box 1 is provided with a slide groove 11 corresponding to the mounting shaft 211. A slider 12 is provided in the slide groove 11. The free end of the mounting shaft 211 passes through the slider 12 and is connected to the first motor 23. The first motor 23 is slidably arranged on the mounting box 1. When in use, the second motor 24 is fixed on the mounting box 1 and is used to drive the second pressure roller 22 to rotate. The second pressure roller 22 only rotates in the mounting box 1 and does not slide. The first motor 23 is slidably arranged on the mounting box 1 and is used to drive the first pressure roller 21 to rotate during the sliding process of the first pressure roller 21. When in use, the first motor 23 is arranged on the mounting seat 25, and the mounting seat 25 is slidably connected to the mounting box 1. The sliding direction of the mounting seat 25 matches the sliding direction of the first pressure roller 21. Preferably, the first motor 23 and the second motor 24 are servo motors. In the present application, the first motor 23 and the second motor 24 are used to rotationally drive the first pressure roller 21 and the second pressure roller 22. In actual use, they can also be driven by other rotation drive mechanisms such as worms. In the present application, a servo motor is used to drive the pressure roller to rotate, which can facilitate the control of the rotation direction and rotation speed of the pressure roller.

[0033] The driving component 3 includes a hydraulic rod 31. The output end of the hydraulic rod 31 is fixedly connected to the mounting seat 25. The hydraulic rod 31 is used to drive the first pressing roller 21 and the first motor 23 to slide along the chute 11, so as to discharge the piled materials. In this application, the hydraulic rod 31 is used to drive the first pressing roller 21 to slide. In actual use, a linear driving mechanism such as a cylinder or an electric telescopic rod can also be set to drive the first pressing roller 21 and the first motor 23 to slide. In this application, the hydraulic rod 31 is used as the driving component, with a simple structure and convenient use. A spring 32 is also arranged between the hydraulic rod 31 and the mounting shaft 211. The purpose of setting the spring 32 is that if the tobacco stem feeding is uneven, resulting in different pressures at both ends between the two rollers, the compression force of the spring 32 is used to offset it, so that the tobacco stem pressing process is stable and there is no noise.

[0034] Preferably, the material receiving component 4 includes a plurality of guide plates 41 rotatably mounted below the extrusion channel and a rotating member for driving the guide plates 41 to rotate. The guide plates 41 can form a guiding channel under the drive of a motor. An opening 42 is arranged at the end of the installation box 1 corresponding to the guiding channel. When not in the material guiding working condition, the guide plates 41 are arranged vertically in a stepped shape in the installation box. At this time, the first pressing roller 21 and the second pressing roller 22 normally extrude the tobacco stems, and the tobacco stems after extrusion can normally fall between the guide plates; when there is a piled material phenomenon above the first pressing roller 21 and the second pressing roller 22, such as Figure 2 , they rotate under the drive of the motor until all the guide plates 41 are connected end to end to form a guiding channel. At this time, the unextruded tobacco stems can fall onto the guiding channel and be discharged from the opening 42. Preferably, a plurality of motors can be set to drive the guide plates 41 respectively. In fact, a structure such as an air-conditioning hinge can also be set to drive the guide plates 41. Thus, the purpose of controlling a plurality of guide plates 41 through one driving source can be achieved. Optionally, a valve plate that can be opened and closed can be arranged at the opening 42 to prevent the tobacco stems from falling out during normal tobacco stem extrusion.

[0035] In this application, according to another alternative embodiment, the material receiving component 4 includes a guide plate 41 rotatably mounted below the extrusion channel and a rotating member for driving the guide plate 41 to rotate. The guide plate 41 is a side plate of the installation box 1. The bottom end of the guide plate 41 is hinged to the installation box 1. In this application, a part of the side plate of the installation box 1 is used as the guide plate 41. During use, the side plate is rotated to receive and guide the falling tobacco stems, and there is no need to additionally open a discharge port on the installation box 1.
