Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, specifically to a bearing transmission mechanism for a leaf trimmer feeder and a leaf trimmer feeder. Background Technology

[0002] A tobacco leaf threshing and re-drying machine is a device that uses mechanical force to tear the leaves of tobacco leaves from the stems. A rotating threshing roller is equipped with rough-surfaced cutting blades. During the rotation of the threshing roller, a certain gap is maintained between it and the fixed blades and the frame, allowing the tobacco leaves to pass through. Due to the relative motion at a certain speed between the moving blades of the threshing roller and the fixed blades and frame, the tobacco leaves are torn and struck as they pass through the threshing machine. During this tearing process, the leaves are ripped from the stems, thus achieving stem-leaf separation, and then the leaves are discharged from the threshing machine through the frame.

[0003] In existing technologies, such as the tobacco stem crusher with patent number CN205361494U, the main purpose is to crush and process tobacco stems and other tobacco-related waste materials online during tobacco re-drying production. This machine includes a tension adjustment seat, a motor, a speed transmission mechanism, a crushing roller, a filter screen frame, a casing, a base, a movable cover, a feed inlet, a discharge collection inlet, a split vertical self-aligning bearing with a seat, a cooling fan, a bearing safety guard, a transmission mechanism safety guard, an inspection door, an observation window, and vibration damping pads. Its key feature is that the motor drives the crushing roller pulley via a drive belt in the speed transmission mechanism, causing the roller to rotate at high speed along the material feeding direction. When the tobacco stems enter from the material inlet, they impact, counter-impact, and collide with the high-speed rotating crushing blades, thus crushing the tobacco stems. Below the beating roller is a filter screen frame, used to screen out tobacco stems that are not completely crushed. When the beating roller rotates, the wind force generated by the blades will roll up the tobacco stems on the filter screen, and under the action of airflow, they will collide with the beating blades again, so that the tobacco stems are fully crushed. The crushed stems fall into the hopper through the filter screen and are discharged through the outlet under the action of external airflow.

[0004] However, the bearing safety guard is large in size and needs to be installed entirely on the outside of the protected structure, which takes up a lot of space and affects the space utilization rate. Utility Model Content

[0005] This application provides a bearing transmission mechanism and a leaf-cutting machine feeder for a leaf-cutting machine, which can solve the problem that the bearing safety guard in the prior art is large in size and needs to be completely covered on the outside of the protected structure, which occupies a lot of space and affects the space utilization rate.

[0006] In a first aspect, embodiments of this application provide a bearing transmission mechanism for a leaf-cutting machine feeder, comprising:

[0007] A first bearing housing and a second bearing housing are provided, which are spaced apart inside the fan duct. The first bearing housing contains a first bearing, and the second bearing housing contains a second bearing.

[0008] The mounting shaft has one end for connection to the drive mechanism and the other end for passing through and connecting the first bearing and the second bearing. The portion of the mounting shaft located between the first bearing and the second bearing is used to mount the screen drum.

[0009] The first sealing cover and the second sealing cover are respectively installed on the outside of the first bearing and the second bearing, and are connected to the first bearing housing and the second bearing housing. The second sealing cover has a mounting hole on the side away from the second bearing, through which the mounting shaft passes, and the mounting hole matches the mounting shaft.

[0010] In one embodiment, a sealing ring is provided on the inner side of the second sealing cover. The sealing ring is located inside the mounting hole, and the inner diameter of the sealing ring is smaller than the diameter of the mounting hole and matches the mounting shaft.

[0011] In one embodiment, the outer periphery of the sealing ring is provided with an annular groove, and the inner side of the second sealing cover is provided with an installation groove that matches the annular groove.

[0012] In one embodiment, the outer periphery of both the first sealing cover and the second sealing cover is provided with a connecting mechanism, which is used to connect the first sealing cover and the first bearing seat, or the second sealing cover and the second bearing seat.

[0013] In one embodiment, the connecting mechanism includes a plurality of ear plates arranged circumferentially along the first or second sealing cover, and connecting bolts passing through the corresponding ear plates, the connecting bolts passing through the ear plates and fixed to the outside of the first or second bearing seat.

[0014] In one embodiment, the first sealing cover and the second sealing cover both have annular cross sections. The outer sides of the first bearing seat and the second bearing seat are provided with tubular bosses. The tubular bosses are coaxially arranged with the mounting shaft and are connected to the first sealing cover or the second sealing cover. The outer diameter of the tubular bosses is the same as the outer diameter of the first sealing cover and the second sealing cover.

[0015] In one embodiment, the outer periphery of the tubular boss is provided with a fixing plate corresponding to the ear plate, and the connecting bolt passing through the ear plate is fixed in the corresponding fixing plate.

[0016] In one embodiment, the inner wall thickness of the first and second sealing covers matches the wall thickness of the tubular boss.

[0017] In one embodiment, both the first sealing cover and the second sealing cover have annular mounting grooves on their inner sides. A sealing gasket is provided in the annular mounting groove. The sealing gasket is used to seal the connection between the first sealing cover and the first bearing seat, or between the second sealing cover and the second bearing seat.

[0018] Secondly, embodiments of this application also provide a leaf-breaking machine feeder, which includes the aforementioned bearing transmission mechanism for a leaf-breaking machine feeder.

[0019] The beneficial effects of the technical solutions provided in this application include:

[0020] When installing the bearing transmission mechanism for the leaf-beating machine feeder, the first bearing housing and the second bearing housing are spaced apart inside the fan duct. The first bearing housing houses the first bearing, and the second bearing housing houses the second bearing. One end of the mounting shaft is used to connect to the drive mechanism, and the other end passes through and connects to the inner rings of the first and second bearings. The portion of the mounting shaft located between the first and second bearings is used to install the screen drum. The first and second sealing covers are respectively installed on the outside of the first and second bearings and are respectively connected to the first and second bearing housings. The side of the second sealing cover away from the second bearing has a mounting hole for the mounting shaft to pass through. With the mounting shaft matching, since the first and second sealing covers are respectively positioned on the outside of the first and second bearings, and the second sealing cover has a mounting hole on the side away from the second bearing for the mounting shaft to pass through, it is not necessary to use a large sealing cover to cover the drive end of the mounting shaft. This can prevent the air in the fan duct from drying out the bearing lubricant in the first and second bearings, and also prevent foreign objects from entering the bearing structure. In addition, the first and second sealing covers occupy a small volume, which solves the problem that the existing bearing safety cover is large in volume and needs to be installed on the outside of the protected structure, resulting in a large space occupation and affecting space utilization.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0031] This application provides a bearing transmission mechanism and a leaf-beating machine feeder for a leaf-beating machine feeder. It can solve the problem that the bearing safety guard in the prior art is large in size and needs to be completely covered on the outside of the protected structure, which occupies a lot of space and affects the space utilization rate.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in one aspect, this application provides a bearing transmission mechanism for a leaf-cutting machine feeder, which includes:

[0033] The first bearing housing 3 and the second bearing housing 7 are used to be spaced apart in the fan duct. The first bearing housing 3 is provided with the first bearing 2, and the second bearing housing 7 is provided with the second bearing 5.

[0034] Mounting shaft 6, one end of which is used to connect to the drive mechanism, and the other end passes through and connects to the first bearing 2 and the second bearing 5.

The second sealing cover 4 has a mounting hole 41 on the side away from the second bearing 5, through which the mounting shaft 6 passes, and the mounting hole 41 matches the mounting shaft 6.

[0036] When installing the bearing transmission mechanism for the leaf-cutting machine feeder, the first bearing housing 3 and the second bearing housing 7 are spaced apart inside the fan duct. The first bearing housing 3 houses the first bearing 2, and the second bearing housing 7 houses the second bearing 5. One end of the mounting shaft 6 is used to connect to the drive mechanism, and the other end passes through and connects to the inner rings of the first bearing 2 and the second bearing 5.

This can prevent the air in the fan duct from drying the bearing lubricant in the first bearing 2 and the second bearing 5, and can also prevent foreign objects from entering the bearing structure. In addition, the first sealing cover 1 and the second sealing cover 4 occupy a small volume, which solves the problem that the bearing safety protection cover in the prior art is large in volume and needs to be installed on the outside of the protected structure, which occupies a lot of space and affects the space utilization rate.

[0037] like Figure 2 , Figure 4 and Figure 6 As shown, in some optional embodiments, a sealing ring 8 is provided on the inner side of the second sealing cover 4. The sealing ring 8 is located inside the mounting hole 41. The inner diameter of the sealing ring 8 is smaller than the diameter of the mounting hole 41 and matches the mounting shaft 6.

The connecting bolts 92 pass through the corresponding ear plates 91 and are fixed to the outside of the first bearing seat 3 or the second bearing seat 7. The structure is simple and easy to connect.

[0046] like Figure 1 , Figure 2 and Figure 3As shown, in some optional embodiments, the cross-section of the first sealing cover 1 and the second sealing cover 4 is annular, and the outer side of the first bearing seat 3 and the second bearing seat 7 is provided with a tubular boss 20.

[0047] In this embodiment, the cross-section of the first sealing cover 1 and the second sealing cover 4 is annular. The outer side of the first bearing seat 3 and the second bearing seat 7 is provided with a tubular boss 20. The tubular boss 20 is coaxially arranged with the mounting shaft 6 and is connected to the first sealing cover 1 or the second sealing cover 4. The outer diameter of the tubular boss 20 is the same as the outer diameter of the first sealing cover 1 and the second sealing cover 4, which facilitates the docking of the first bearing seat 3 and the second bearing seat 7 with the first sealing cover 1 and the second sealing cover 4, and also has a certain positioning effect.

[0048] In this example, an oil filling pipe 201 is provided on the outside of the tubular boss 20. The oil filling pipe 201 corresponds to the first bearing 2 or the second bearing 5 and is used to add lubricant to the bearing.

The sealing gaskets 10 are used to seal the connection between the first sealing cover 1 and the first bearing seat 3, or between the second sealing cover 4 and the second bearing seat 7.

[0054] In this embodiment, an annular mounting groove is provided on the inner side of both the first sealing cover 1 and the second sealing cover 4. A sealing gasket 10 is provided in the annular mounting groove. The sealing gasket 10 is used to seal the connection between the first sealing cover 1 and the first bearing seat 3, or the second sealing cover 4 and the second bearing seat 7, to further improve the sealing effect.

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, on the other hand, this application also provides a leaf-breaking machine feeder, which includes the above-mentioned bearing transmission mechanism for a leaf-breaking machine feeder.

[0056] When installing the bearing transmission mechanism for the leaf-cutting machine feeder, the first bearing housing 3 and the second bearing housing 7 are spaced apart inside the fan duct. The first bearing housing 3 houses the first bearing 2, and the second bearing housing 7 houses the second bearing 5. One end of the mounting shaft 6 is used to connect to the drive mechanism, and the other end passes through and connects to the inner rings of the first bearing 2 and the second bearing 5. The portion of the mounting shaft 6 located between the first bearing 2 and the second bearing 5 is used to install the screen drum. The first sealing cover 1 and the second sealing cover 4 are respectively installed on the outside of the first bearing 2 and the second bearing 5, and are respectively connected to the first bearing housing 3 and the second bearing housing 7. The side of the second sealing cover 4 away from the second bearing 5 has a mounting hole 41 through which the mounting shaft 6 passes. The mounting hole 41 matches the mounting shaft 6. Since the first sealing cover 1 and the second sealing cover 4 are respectively installed on the outside of the first bearing 2 and the second bearing 5, and the second sealing cover 4 has a mounting hole 41 on the side away from the second bearing 5 for the mounting shaft 6 to pass through, it is not necessary to use a large sealing cover to cover the drive end of the mounting shaft 6. This can prevent the air in the fan duct from drying the bearing lubricant in the first bearing 2 and the second bearing 5, and can also prevent foreign objects from entering the bearing structure. In addition, the first sealing cover 1 and the second sealing cover 4 occupy a small volume, which solves the problem that the bearing safety protection cover in the prior art is large in volume and needs to be installed on the outside of the protected structure, which occupies a lot of space and affects the space utilization rate.
