Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing, in particular to a roller mechanism and a tobacco laying vehicle. Background Art

[0002] During the production and transportation of tobacco, tobacco materials that have undergone vacuum rehydration, loose rehydration and other processes must be stored in leaf storage cabinets. A spreading car is provided on the top of the leaf storage cabinet. The spreading car is used to transport tobacco materials into the leaf storage cabinet. At the same time, the tobacco materials entering the spreading car are spread out in strips, so that the tobacco materials can more fully absorb the moisture and liquid applied to the tobacco materials in the previous process, which helps the tobacco materials to be mixed evenly after entering the leaf storage cabinet, so as to meet the requirements of the process line.

[0003] In the actual production process, as the equipment ages, the roller mechanism of the material laying vehicle often fails, which may cause the vehicle to stop in serious cases. The ends of the roller shaft and roller are easily damaged due to long-term wear, while the roller shaft and roller located in the middle of the roller mechanism are relatively well preserved and less worn.

[0004] When the shaft heads at both ends of the roller shaft are damaged, the entire roller shaft needs to be removed and the roller drum installed on the new roller shaft. During the replacement process, the disassembly and installation between the roller shaft and the roller drum are complicated and cumbersome, and the middle area of ​​the scrapped roller shaft is not damaged, resulting in low equipment utilization, increased maintenance costs, and increased tobacco production costs.

[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Combine the following Figure 1-Figure 3 , through specific embodiments and application scenarios, the roller mechanism and tobacco laying vehicle provided by the embodiment of the utility model are described in detail.

[0037] like Figure 1-Figure 3 As shown, the utility model provides a roller mechanism, comprising: a roller 1 and a roller shaft 2.

[0038] The roller shaft 2 comprises a shaft body 21, a first shaft head 22 and a second shaft head 23. The roller 1 is sleeved on the shaft body 21, and a first connecting component 3 and a second connecting component 4 are respectively disposed at two ends of the roller 1.

[0039] Two ends of the shaft body 21 are respectively disposed at the first end of the first connecting component 3 and the first end of the second connecting component 4 .

[0040] The first shaft head 22 is detachably disposed at the second end of the first connecting component 3 , and the second shaft head 23 is detachably disposed at the second end of the second connecting component 4 .

[0041] It is understandable that roller mechanisms are often used in tobacco processing conveying equipment, such as tobacco spreading vehicles. The tobacco spreading vehicle uses a strip-shaped spreading method to spread and transport tobacco materials. In order to achieve the spreading and transportation of tobacco materials, a roller mechanism is provided in the tobacco spreading vehicle, and the roller mechanism provides power for the movement of the tobacco materials.

[0042] In general, such as Figure 1As shown, the first shaft head 22 and the second shaft head 23 located at both ends of the shaft body 21 are exposed. The first shaft head 22 or the second shaft head 23 is connected to the driving motor and other equipment. The force on the first shaft head 22 and the second shaft head 23 is relatively complex. During long-term use, they are prone to wear and damage. The shaft body 21 is located in the middle area of ​​the roller shaft 2, and the force is relatively uniform. The shaft body 21 is wrapped in the roller 1 and is not easily damaged. The shaft body of the traditional roller mechanism and the shaft heads at both ends are formed as a whole by injection molding. When the shaft heads are damaged, the entire roller shaft needs to be replaced. However, the intact shaft body of the replaced roller shaft can no longer be put into use, resulting in an increase in maintenance costs and a gradual increase in the production cost of tobacco. The shaft body 21, the first shaft head 22 and the second shaft head 23 of the present application are detachably connected. When any sub-component of the roller shaft 2 is damaged, it is only necessary to replace the damaged sub-component in a targeted manner, and the remaining sub-components that are not damaged can continue to be used, thereby saving the maintenance cost of the roller mechanism.

[0043] Specifically, Figure 1 As shown, the roller 1 is sleeved on the shaft body 21. During installation, the roller 1 can be sleeved on the shaft body 21 with the help of a hammer or other tools, and the roller 1 and the shaft body 21 are closely fitted, so that the roller shaft 2 can drive the roller 1 to rotate when the roller shaft 2 is connected to the driving motor.

[0044] The roller mechanism also includes a first connecting component 3 and a second connecting component 4. Specifically, the first connecting component 3 and the second connecting component 4 are respectively arranged at the two ends of the roller 1. The overall shape of the first connecting component 3 and the overall shape of the second connecting component 4 are both cylindrical. The circumferential dimensions of the first connecting component 3 and the second connecting component 4 are the same as the circumferential dimensions of the roller 1. The first end of the first connecting component 3 and the first end of the second connecting component 4 are respectively attached to the end faces of the two ends of the roller 1, and both are arranged flush with the outer edges of the two end faces of the roller 1.

[0045] At the same time, Figure 1 As shown, the two ends of the shaft body 21 are detachably arranged at the first end of the first connecting component 3 and the first end of the second connecting component 4. The first shaft head 22 is detachably arranged at the second end of the first connecting component 3. The second shaft head 23 is detachably arranged at the second end of the second connecting component 4. Thus, the connection between the first shaft head 22 and the shaft body 21 and the roller 1 is realized through the first connecting component 3, and the connection between the second shaft head 23 and the shaft body 21 and the roller 1 is realized through the second connecting component 4.

[0046] During assembly, firstly, the shaft body 21 is passed through the roller 1; then, one end of the shaft body 21 is embedded in the first end of the first connecting component 3, and the first end of the first connecting component 3 is fixed to one end of the roller 1; then, a part of the first shaft head 22 is embedded in the second end of the first connecting component 3; then, the other end of the shaft body 21 is embedded in the first end of the second connecting component 4, and the first end of the second connecting component 4 is fixed to the other end of the roller 1; finally, a part of the second shaft head 23 is embedded in the second end of the second connecting component 4.

[0047] It should be noted that the first end and the second end of the first connecting component 3 are two opposite ends in the extending direction of the first connecting component 3 .

[0048] When the first shaft head 22 is damaged, it is only necessary to remove the first shaft head 22 from the second end of the first connecting component 3, and then insert a part of the new first shaft head 22 into the first connecting component 3. The undamaged second shaft head 23 and the shaft body 21 continue to be used.

[0049] The utility model provides a roller mechanism, wherein a first connecting component 3 and a second connecting component 4 are respectively fixed at two ends of a roller 1, a shaft body 21 is penetrated through the roller 1, and two ends of the shaft body 21 are respectively fixed to the first end of the first connecting component 3 and the first end of the second connecting component 4, so as to ensure the stability of the connection between the shaft body 21 and the roller 1; at the same time, a first shaft head 22 is detachably arranged at the second end of the first connecting component 3, and a second shaft head 23 is detachably arranged at the second end of the second connecting component 4, so that when the first shaft head 22 or the second shaft head 23 is damaged, the first shaft head 22 or the second shaft head 23 can be directly removed, and then a new first shaft head 22 or the second shaft head 23 can be replaced and installed to the first connecting component 3 or the second connecting component 4, which is convenient for maintenance, and the remaining sub-components that are not damaged in the roller mechanism can still be used, which is beneficial to improving the utilization rate of equipment resources, saving maintenance costs, and thus reducing the production cost of tobacco.

[0050] like Figure 2 As shown, in some embodiments, the first connecting assembly 3 and the second connecting assembly 4 are both provided with connecting holes 301. The extending direction of the connecting holes 301 coincides with the axial direction of the shaft body 21.

[0051] Two ends of the shaft body 21 are respectively inserted into the first ends of the two connecting holes 301 .

[0052] At least a portion of the first shaft head 22 is inserted into the second end of the connecting hole 301 , and at least a portion of the second shaft head 23 is inserted into the second end of the other connecting hole 301 .

[0053] It is understandable that the specific structures of the first connecting component 3 and the second connecting component 4 can be the same. Taking the first connecting component 3 as an example, Figure 2As shown, a connection hole 301 is provided in the middle area of ​​the first connection component 3. The connection hole 301 runs through the first connection component 3, and the extension direction of the connection hole 301 is arranged parallel to the extension direction of the shaft body 21. The connection hole 301 has a sufficient depth to ensure the stability of the connection between the first shaft head 22 and the shaft body 21. The outer edge of the first connection component 3 is fixed to one end of the roller 1. The end of the connection hole 301 close to the roller 1 is the first end, and the end of the connection hole 301 away from the roller 1 is the second end.

[0054] Specifically, one end of the shaft body 21 is embedded in the first end of the connecting hole 301 , and a portion of the first shaft head 22 is embedded in the second end of the connecting hole 301 .

[0055] In an optional embodiment, during assembly, the first connecting component 3 can be struck toward the shaft body 21 by means of a hammer 100, so that the first end of the connecting hole 301 is driven into one end of the shaft body 21; after one end of the shaft body 21 is tightly embedded in the first end of the connecting hole 301, the outer edge of the first end of the first connecting component 3 is fixed to one end of the roller 1; then, a part of the first shaft head 22 is driven into the second end of the connecting hole 301. The connection between the second connecting component 4 and the shaft body 21, the roller 1 and the second shaft head 23 can be the same as above, and no further description is given.

[0056] In another optional embodiment, the hole walls of the connecting holes 301 of the first connecting component 3 and the second connecting component 4 are both provided with internal threads. Both ends of the shaft body 21 are provided with external threads adapted to the internal threads. Correspondingly, the first shaft head 22 and the second shaft head 23 are also provided with external threads. During assembly, the external threads at both ends of the shaft body 21 are respectively threadedly connected with the internal threads at the first ends of the two connecting holes 301; then the outer edge of the first end of the first connecting component 3 and the outer edge of the first end of the second connecting component 4 are respectively fixed to the two ends of the roller 1; then, the external thread of the first shaft head 22 is threadedly connected with the internal thread of the second end of the first connecting component 3, and then the external thread of the second shaft head 23 is threadedly connected with the internal thread of the second end of the second connecting component 4.

[0057] In some embodiments, Figure 1 As shown, the first connecting member and the second connecting member both include a positioning portion 31 and a reinforcing portion 32. The positioning portion 31 is fixedly connected to the reinforcing portion 32, and the connecting hole 301 passes through the positioning portion 31 and the reinforcing portion 32 in sequence.

[0058] The two reinforcement parts 32 are respectively fixed to the two ends of the roller 1. The two ends of the shaft body 21 are respectively inserted in the two reinforcement parts 32. At least a part of the first shaft head 22 and at least a part of the second shaft head 23 are respectively inserted in the two positioning parts 31.

[0059] It is understandable that, on the one hand, the first connecting component 3 needs to have a sufficient axial length, and the length of the shaft body 21 and the first shaft head 22 embedded in the connecting hole 301 must be relatively long, so as to ensure the effective connection between the shaft body 21, the first connecting component 3 and the first shaft head 22; on the other hand, in actual use, the two ends of the roller 1 are also prone to cracking and damage.

[0060] Therefore, the first connecting member and the second connecting member are both provided with a positioning portion 31 and a reinforcing portion 32. In this embodiment, the specific structure of the second connecting component 4 can be the same as that of the first connecting component 3. Taking the first connecting component 3 as an example, the positioning portion 31 and the reinforcing portion 32 both have sufficient supporting strength and wear resistance. Specifically, as Figure 1 As shown, the positioning portion 31 and the reinforcing portion 32 are stacked along the extension direction of the first connecting component 3. The reinforcing portion 32 is located at the first end of the first connecting component 3, and the positioning portion 31 is located at the second end of the first connecting component 3. The outer edge of the reinforcing portion 32 is fixed to the roller 1. The reinforcing portion 32 is sandwiched between the roller 1 and the positioning portion 31. The length of the reinforcing portion 32 along the extension direction of the first connecting component 3 is greater than the length of the positioning portion 31 along the extension direction of the first connecting component 3.

[0061] Specifically, the connection hole 301 passes through the reinforcement portion 32 and the positioning portion 31, that is, the first end of the connection hole 301 is located at the reinforcement portion 32, and the second end of the connection hole 301 is located at the positioning portion 31. The end of the shaft body 21 is embedded in the portion of the connection hole 301 located at the reinforcement portion 32, and a portion of the first shaft head 22 is embedded in the portion of the connection hole 301 located at the positioning portion 31.

[0062] In a preferred embodiment, the positioning portion 31 is a positioning flange, the reinforcement portion 32 is a steel cylinder, and the roller 1 is a plastic cylinder.

[0063] It is understandable that the positioning flange has a simple structure and can effectively limit the reinforcing part 32 and the roller 1, and can also ensure the stable connection between the first shaft head 22, the shaft body 21 and the second shaft head 23. The reinforcing part 32 adopts a steel cylinder, which is arranged at the parts of the roller 1 where the force is uneven at both ends to achieve physical protection for the roller 1, with better durability and less prone to damage. The roller 1 is located in the middle area of ​​the roller mechanism, where the force is small and uniform, and a plastic cylinder made of plastic material is used to save equipment costs.

[0064] Specifically, in some embodiments, Figure 1 As shown, the roller mechanism also includes a fixing member 5. The reinforcing portion 32 is provided with a threaded hole 321, and the positioning portion 31 is provided with a positioning hole 311. Both ends of the roller 1 are provided with positioning columns 11. The positioning columns 11 are sequentially penetrated through the threaded hole 321 and the positioning hole 311, and are threadedly connected to the fixing member 5.

[0065] It is understandable that both end faces of the roller 1 are provided with positioning posts 11. Correspondingly, the reinforcement portion 32 is provided with a threaded hole 321, and the positioning portion 31 is provided with a positioning hole 311. The threaded hole 321 and the positioning hole 311 are arranged relative to each other. The size of the positioning post 11 is adapted to the size of the threaded hole 321 and the positioning hole 311. The fixing member 5 is sleeved on the positioning post 11. During assembly, the positioning post 11 is sequentially inserted into the threaded hole 321 and the positioning hole 311, and then the fixing member 5 is tightened, and the fixing member 5 is set against the end face of the positioning portion 31, thereby limiting the positioning portion 31 and the reinforcement portion 32 to the end face of the roller 1. Optionally, the fixing member 5 can be a nut.

[0066] Furthermore, if Figure 1 As shown, a plurality of positioning posts 11 are provided at both ends of the roller 1. The plurality of positioning posts 11 are sequentially spaced apart along the circumference of the roller 1.

[0067] It is understandable that, correspondingly, the fixing member 5 is also provided with a plurality of them. The positioning portion 31 is provided with a plurality of positioning holes 311. The plurality of positioning holes 311 are sequentially arranged at intervals along the circumference of the positioning portion 31. The reinforcing portion 32 is provided with a plurality of threaded holes 321. The plurality of threaded holes 321 are sequentially arranged at intervals along the circumference of the reinforcing portion 32.

[0068] The plurality of positioning holes 311 and the plurality of threaded holes 321 are arranged one by one in a relative manner, and the plurality of positioning posts 11 are arranged one by one in sequence through the plurality of positioning holes 311 and the plurality of threaded holes 321, and the plurality of fixing members 5 are tightened one by one in a relative manner to achieve the fixing of the first connecting component 3 with the second connecting component 4 and the roller 1. At the same time, the arrangement of the positioning posts 11 can position the first connecting component 3 with the second connecting component 4 to prevent the first connecting component 3, the second connecting component 4 and the roller 1 from rotating relative to each other. Among them, the number of fixing members 5, positioning holes 311, and threaded holes 321 is consistent with the number of positioning posts 11. Optionally, the number of positioning posts 11 is three, four, or six, etc.

[0069] In some embodiments, the roller mechanism further includes a bushing. The bushing is cylindrical, and the extension direction of the bushing is parallel to the extension direction of the connecting hole 301. The inner wall of the bushing is connected to the roller shaft 2, and the outer wall of the bushing is connected to the hole wall of the connecting hole 301.

[0070] Wherein, the first bushing comprises a high damping vibration reduction bushing.

[0071] It is understandable that the bushing is cylindrical. The bushing is arranged on the hole wall of the connection hole 301. The bushing and the hole wall of the connection hole 301 may be connected by vulcanization connection or cold expansion, or the bushing is connected to the hole wall of the connection hole 301 by bolts. The inner side wall of the bushing is used to connect with the shaft body 21, the first shaft head 22 and / or the second shaft head 23.

[0072] When the roller shaft 2 is connected to the drive motor, when the output power of the drive motor is unstable, the roller shaft 2 may vibrate. In one embodiment, the bushing may be a high-damping vibration-reducing bushing made of rubber or polymer. By arranging a high-damping vibration-reducing bushing in the connecting hole 301, when the roller shaft 2 vibrates, the bushing absorbs vibration energy through the damping effect, reduces vibration capacity, reduces vibration transmission, reduces vibration load on the roller 1, and improves the reliability of the roller 1.

[0073] In some embodiments, Figure 1 and Figure 3 As shown, one end of the first shaft head 22 away from the first connecting component 3 and one end of the second shaft head 23 away from the second connecting component 4 are both provided with a countersunk hole 221 , and the countersunk hole 221 is used to insert the hammer 100 .

[0074] It is understandable that the specific structure of the second shaft head 23 can be the same as that of the first shaft head 22. Taking the first shaft head 22 as an example, in order to facilitate the first shaft head 22 to be quickly driven into the connecting hole 301, as shown in FIG. Figure 3 As shown, a countersunk hole 221 is also provided at one end of the first shaft head 22 away from the first connecting component 3. The extension direction of the countersunk hole 221 is arranged parallel to the extension direction of the first shaft head 22. When it is necessary to drive the end of the first shaft head 22 away from the countersunk hole 221 into the connecting hole 301, the hammer 100 can be inserted into the countersunk hole 221. The countersunk hole 221 can provide a fulcrum for the hammer 100 to hammer the first shaft head 22, thereby ensuring the stability of the connection between the first shaft head 22 and the first connecting component 3. After the first shaft head 22 is tightly embedded in the connecting hole 301, the hammer 100 can be removed from the countersunk hole 221.

[0075] In a second aspect, the utility model further provides a tobacco laying vehicle, comprising a plurality of roller mechanisms as described above.

[0076] Since the tobacco laying trolley includes a roller mechanism, the specific structure of the tobacco laying trolley refers to the above embodiment, and the tobacco laying trolley of this embodiment includes all the technical solutions of the above embodiment, and therefore at least has all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here one by one.

[0077] In some embodiments, the tobacco laying vehicle further comprises a conveying frame and a conveying belt. A plurality of roller mechanisms are arranged on the conveying frame and are sequentially spaced apart along the extending direction of the conveying frame.

[0078] The conveyor belt is sleeved on a plurality of rollers 1, and is used to convey the shredded tobacco to the leaf storage cabinet.

[0079] It is understandable that the roller mechanism is used to be arranged on the tobacco laying vehicle. The conveyor frame is in a rectangular parallelepiped shape. The conveyor frame is used to provide support for multiple roller mechanisms. Multiple rollers 1 are arranged at equal distances along the extension direction of the conveyor frame, and the multiple rollers 1 are perpendicular to the extension direction of the conveyor frame.

[0080] The conveyor frame is also provided with two side plates. The extension direction of the side plates is arranged parallel to the conveying direction of the conveyor belt. The conveyor belt is located between the two side plates. The two side plates can prevent the tobacco material on the conveyor belt from falling out from the edge of the conveyor belt.

[0081] A plurality of limiting grooves are arranged on both side plates. The plurality of limiting grooves are arranged at equal intervals along the extending direction of the side plates. In particular, along the conveying direction of the conveying ring belt, every two limiting grooves on opposite sides of the conveying ring belt are aligned.

[0082] One end of the first shaft head 22 of each roller mechanism away from the first connecting component 3 and one end of the second shaft head 23 away from the first connecting component 3 are respectively accommodated in two aligned limiting grooves.

[0083] Each roller mechanism is equipped with a driving motor, and the output end of the driving motor is rotatably connected to the first shaft head 22 or the second shaft head 23. Specifically, taking one of the roller mechanisms as an example, the output end of the driving motor is rotatably connected to the first shaft head 22. Bearing supports are fixed on the walls of the two aligned limit grooves. The end of the first shaft head 22 away from the first connecting component 3 is inserted into one of the bearing supports and connected to the output end of the driving motor; the end of the second shaft head 23 away from the second connecting component 4 is inserted into the other bearing support. The driving motor drives the first shaft head 22 to rotate, and then the first shaft head 22 drives the first connecting component 3, the roller 1, the second connecting component 4 and the second shaft head 23 to rotate synchronously.
