Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a conveying mechanism and stripping equipment. Background Art

[0002] Conveyor rollers are often used to convey strip materials such as wood strips or bamboo strips. Conveyor rollers are generally configured in two, and the two conveyor rollers are spaced apart from each other, and the strip material is located between the two conveyor rollers.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0053] like Figures 1 to 5 As shown, an embodiment of the utility model provides a conveying mechanism for conveying strip materials, and the conveying mechanism includes: a first conveying roller 111, a second conveying roller 112, a driving unit 12 and a base 13; the first conveying roller 111 and the second conveying roller 112 are both rotatably arranged on the base 13; the first conveying roller 111 and the second conveying roller 112 are arranged at intervals, and a conveying space 113 is formed between the first conveying roller 111 and the second conveying roller 112; the driving unit 12 is used to drive the first conveying roller 111 and the second conveying roller 112 to rotate synchronously, so that the strip materials entering the conveying space 113 can move in a preset direction; the first conveying roller 111 can swing in a direction close to or away from the second conveying roller 112, and / or the second conveying roller 112 can swing in a direction close to or away from the first conveying roller 111.

[0054] The conveying mechanism provided in this embodiment includes a first conveying roller 111, a second conveying roller 112, a driving unit 12 and a base 13. The first conveying roller 111 and the second conveying roller 112 are both rotatably mounted on the base 13, and the first conveying roller 111 and the second conveying roller 112 are arranged at intervals to define a conveying space 113 between the first conveying roller 111 and the second conveying roller 112. The output end of the driving unit 12 is simultaneously connected to the first conveying roller 111 and the second conveying roller 112 in a transmission manner, so that the first conveying roller 111 and the second conveying roller 112 can be driven to rotate synchronously, so that the strip material in the conveying space 113 between the first conveying roller 111 and the second conveying roller 112 can move along a preset direction.

[0055] Furthermore, in the present embodiment, the first conveying roller 111 can swing toward or away from the second conveying roller 112, and / or the second conveying roller 112 can swing toward or away from the first conveying roller 111, so as to adjust the spacing between the first conveying roller 111 and the second conveying roller 112, thereby being able to accommodate strip materials of different thicknesses.

[0056] In this embodiment, the first conveying roller 111 may be swingably set on the base 13 so that the first conveying roller 111 can swing toward or away from the second conveying roller 112, thereby reducing or increasing the size of the conveying space 113; or, the second conveying roller 112 may be swingably set on the base 13 so that the second conveying roller 112 can swing toward or away from the first conveying roller 111, thereby reducing or increasing the size of the conveying space 113; or, the first conveying roller 111 may swing toward or away from the second conveying roller 112, and at the same time, the second conveying roller 112 may also swing toward or away from the first conveying roller 111, thereby adjusting the size of the conveying space 113.

[0057] Preferably, in this embodiment, in order to allow the conveying space 113 to have a larger adjustment range, this embodiment adopts an implementation method in which the first conveying roller 111 can swing toward or away from the second conveying roller 112, and at the same time, the second conveying roller 112 can also swing toward or away from the first conveying roller 111. The specific content is explained in detail below.

[0058] The conveying mechanism provided in this embodiment can realize the conveying of strip materials by driving the first conveying roller 111 and the second conveying roller 112 which are arranged at intervals to rotate synchronously through the driving unit 12. The first conveying roller 111 can swing toward or away from the second conveying roller 112, and / or the second conveying roller 112 can swing toward or away from the first conveying roller 111, and the size of the conveying space 113 between the first conveying roller 111 and the second conveying roller 112 can be adjusted, so that the conveying mechanism can adapt to strip materials of different specifications and sizes, and has stronger applicability compared with the prior art.

[0059] The conveying mechanism provided by the embodiment of the utility model is as follows: Figure 1 and Figure 3 As shown, it also includes a first gear 21, a second gear 22, a third gear 23 and a fourth gear 24; the first conveying roller 111 is coaxially arranged with the first gear 21, and the second conveying roller 112 is coaxially arranged with the second gear 22; the driving unit 12 is transmission-connected with the third gear 23, the fourth gear 24 is meshed with the third gear 23, the second gear 22 is meshed with the fourth gear 24, and the first gear 21 is only meshed with the third gear 23.

[0060] As mentioned above, the driving unit 12 can drive the first conveying roller 111 and the second conveying roller 112 to rotate synchronously. Furthermore, a transmission unit is provided between the driving unit 12 and the first conveying roller 111 and the second conveying roller 112 to realize that the driving unit 12 drives the first conveying roller 111 and the second conveying roller 112 to rotate synchronously. It should be noted that in order to ensure that the first conveying roller 111 and the second conveying roller 112 can convey strip materials, the first conveying roller 111 and the second conveying roller 112 rotate in opposite directions.

[0061] Specifically, in this embodiment, the transmission unit includes a first gear 21, a second gear 22, a third gear 23 and a fourth gear 24. The drive unit 12 can be a drive motor, an internal combustion engine or a hydraulic motor. The output end of the drive unit 12 is connected to the third gear 23 for driving the third gear 23 to rotate. The fourth gear 24 is meshed with the third gear 23, and the second gear 22 is also meshed with the fourth gear 24, that is, the third gear 23 drives the fourth gear 24 to rotate, and the fourth gear 24 drives the second gear 22 to rotate; the first gear 21 is only meshed with the third gear 23, that is, the first gear 21 is not meshed with other gears except the third gear 23, and the rotation of the third gear 23 can drive the first gear 21 to rotate. The first conveyor roller 111 is coaxially arranged with the first gear 21, that is, the first conveyor roller 111 and the first gear 21 are installed on the same shaft. When the first gear 21 rotates, the first conveyor roller 111 will also rotate accordingly. The second conveyor roller 112 is coaxially arranged with the second gear 22, that is, the second conveyor roller 112 and the second gear 22 are installed on the same shaft. When the second gear 22 rotates, the second conveyor roller 112 will also rotate accordingly.

[0062] Furthermore, the first gear 21 is only meshed with the third gear 23, that is, the rotation direction of the first gear 21 is opposite to that of the third gear 23, and the rotation direction of the first conveying roller 111 is opposite to that of the third gear 23; and the second gear 22 is meshed with the fourth gear 24, and the fourth gear 24 is meshed with the third gear 23, that is, the rotation direction of the second gear 22 is the same as that of the third gear 23, and the rotation direction of the second conveying roller 112 is the same as that of the third gear 23. In this way, the purpose of the rotation direction of the first conveying roller 111 being opposite to that of the second conveying roller 112 can be achieved.

[0063] It is understandable that, in this embodiment, the driving unit 12 can also use two motors that can rotate synchronously to drive the first conveying roller 111 and the second conveying roller 112 to rotate respectively, which can also achieve the purpose of the driving unit 12 in this embodiment driving the first conveying roller 111 and the second conveying roller 112 to rotate synchronously.

[0064] The conveying mechanism provided by the embodiment of the utility model is as follows: Figure 1 and Figure 3 As shown, the transmission unit also includes a first pulley 25, a second pulley 26 and a transmission belt 27; the driving unit 12 has an output shaft, and the first pulley 25 is arranged on the output shaft of the driving unit 12; the second pulley 26 is coaxially arranged with the third gear 23, and the transmission belt 27 transmits and connects the first pulley 25 and the second pulley 26.

[0065] Furthermore, in the present embodiment, the output shaft of the driving unit 12 and the third gear 23 are connected to each other by means of a pulley and a transmission belt 27. Specifically, the transmission unit further includes a first pulley 25, a second pulley 26 and a transmission belt 27. The first pulley 25 is mounted on the output shaft of the driving unit 12, and the driving unit 12 drives the first pulley 25 to rotate. The second pulley 26 is coaxially arranged with the third gear 23, that is, the second pulley 26 and the third gear 23 are arranged on the same shaft. The first pulley 25 and the second pulley 26 are connected by a transmission belt 27. When in use, the first pulley 25 is driven to rotate by the driving unit 12, and the second pulley 26 rotates under the action of the transmission belt 27, thereby driving the coaxial third gear 23 to rotate, and the first gear 21, the fourth gear 24 and the second gear 22 rotate accordingly.

[0066] It is understandable that, in this embodiment, the output shaft of the drive unit 12 and the third gear 23 may also be matched through a chain or a sprocket, which can also achieve the purpose of transmission connection between the output shaft of the drive unit 12 and the third gear 23.

[0067] The conveying mechanism provided by the embodiment of the utility model is as follows: Figure 1 and Figure 4 As shown, it also includes a first bracket 151 and a first telescopic unit 31; a first mounting shaft 141 is provided on the base 13, and the third gear 23 is provided on the first mounting shaft 141; one end of the first bracket 151 is rotatably connected to the first mounting shaft 141, and the other end is provided with a rotatable first rotating shaft 161, and the first gear 21 and the first conveying roller 111 are both fixedly mounted on the first rotating shaft 161; one end of the first telescopic unit 31 is rotatably connected to the base 13, and the other end is rotatably connected to one end of the first bracket 151 away from the first mounting shaft 141.

[0068] The above content mentioned that the first conveying roller 111 and the second conveying roller 112 are both swingably set on the base 13. Specifically, the base 13 has two opposite front and back sides, and two oppositely set mounting plates are provided on the front side. The first mounting shaft 141 and the second mounting shaft 142 mentioned below are both rotatably connected to the two mounting plates at both ends. The third gear 23 and the first pulley 25 are both fixed on the first mounting shaft 141. One end of the first bracket 151 is rotatably connected to the first mounting shaft 141 through a hole opened on the first bracket 151, and the other end is provided with a first rotating shaft 161, and the first rotating shaft 161 is rotatably set on the first bracket 151. The first gear 21 and the first conveying roller 111 are both fixed on the first rotating shaft 161, so that the first gear 21 can drive the first conveying roller 111 to rotate through the first rotating shaft 161. A first telescopic unit 31 is also provided on the front side of the base 13. The first telescopic unit 31 has a telescopic function. One end of the first telescopic unit 31 is rotatably connected to the base 13, and the other end is rotatably connected to one end of the first bracket 151 away from the first mounting shaft 141. Through the telescopic movement of the first telescopic unit 31, the first bracket 151 can be driven to swing on the first mounting shaft 141, thereby achieving the purpose of driving the first conveying roller 111 to move in a direction close to or away from the second conveying roller 112.

[0069] In this embodiment, when the first bracket 151 swings, the first gear 21 rotates around the axis of the third gear 23. That is to say, when the first bracket 151 swings, the first gear 21 and the third gear 23 can always remain engaged, so that no matter how the first bracket 151 swings, the third gear 23 can drive the first gear 21 to rotate.

[0070] Optionally, in this embodiment, the first telescopic unit 31 may also be realized by cooperation between a motor and a cam, but it will be more difficult to adjust the swing amplitude.

[0071] In this embodiment, the first bracket 151 is two plates arranged opposite to each other, and the distance between the two plates can be fixed by the first connecting shaft 17 and the shaft sleeve arranged on the first installation shaft 141 and other structures.

[0072] The conveying mechanism provided by the embodiment of the utility model is as follows: Figure 1 and Figure 4 As shown, the first telescopic unit 31 includes a cylinder body 311 and a piston 312, and the piston 312 is arranged on the cylinder body 311; an avoidance hole 131 is opened on the base 13, and a third bracket 153 is provided at the edge of the avoidance hole 131; the cylinder body 311 is rotatably connected to the third bracket 153, and the end of the cylinder body 311 away from the piston 312 is located in the avoidance hole 131, and the piston 312 is rotatably connected to the first bracket 151.

[0073] Further, in this embodiment, the first telescopic unit 31 can be any one of a pneumatic cylinder, an oil cylinder or an electric cylinder, and a pneumatic cylinder is preferably used in this embodiment. The first telescopic unit 31 is composed of a cylinder body 311 and a piston 312, and the piston 312 is installed on the cylinder body 311, and the cylinder body 311 can drive the piston 312 to extend and retract. A avoidance hole 131 is also provided on the base 13, and the avoidance hole 131 is used to provide space for the installation of the cylinder body 311, so as to reduce the space occupied by the conveying mechanism. The avoidance hole 131 can be a countersunk hole or a through hole. In order to facilitate the arrangement of the gas path system, the avoidance hole 131 is preferably a through hole. The edge of the avoidance hole 131 is provided with a third bracket 153, and the third bracket 153 is used to install the cylinder body 311 of the first telescopic unit 31. Specifically, the cylinder body 311 of the first telescopic unit 31 is rotated and installed on the third bracket 153 through the hole opened on the cylinder body 311 and the shaft on the third bracket 153. Furthermore, after the cylinder body 311 is assembled, one end of the cylinder body 311 away from the piston 312 is located in the avoidance hole 131 to prevent the base 13 from interfering with the rotation of the cylinder body 311 .

[0074] The conveying mechanism provided by the embodiment of the utility model is as follows: Figure 1 and Figure 4 As shown, a first connecting shaft 17 is fixedly disposed on one end of the first bracket 151 away from the first installation shaft 141 , and an end of the first telescopic unit 31 away from the base 13 is rotatably connected to the first connecting shaft 17 .

[0075] Furthermore, in the present embodiment, a first connecting shaft 17 is fixedly provided at one end of the first bracket 151 away from the first mounting shaft 141, and an end of the piston 312 of the first telescopic unit 31 away from the cylinder body 311 of the first telescopic unit 31 cooperates with the first connecting shaft 17 to realize a rotational connection between the first telescopic unit 31 and the first bracket 151.

[0076] It can be understood that, in this embodiment, the cylinder body 311 and the base 13, and the piston 312 and the first bracket 151 can be rotatably connected via a universal joint.

[0077] In this embodiment, it is mentioned above that the first conveying roller 111 may also remain stationary, and the spacing between the first conveying roller 111 and the second conveying roller 112 can be adjusted only by the swing of the second conveying roller 112. In this way, the first bracket 151 can be fixed on the base 13, or the first telescopic unit 31 can be set as a fixed connecting rod, so that the purpose of preventing the first conveying roller 111 from swinging can be achieved.

[0078] The conveying mechanism provided by the embodiment of the utility model is as follows: Figure 2 and Figure 5As shown, it also includes a second bracket 152 and a second telescopic unit 32; a second mounting shaft 142 is provided on the base 13, and the fourth gear 24 is provided on the second mounting shaft 142; the second bracket 152 is rotatably provided on the second mounting shaft 142, and one end of the second bracket 152 is rotatably provided with a second rotating shaft 162, and the second gear 22 and the second conveying roller 112 are both fixedly provided on the second rotating shaft 162; one end of the second telescopic unit 32 is rotatably connected to one end of the second bracket 152 away from the second rotating shaft 162, and the other end is rotatably connected to the base 13.

[0079] Preferably, in this embodiment, in order to allow the spacing between the first conveying roller 111 and the second conveying roller 112 to have a larger adjustment range, the second conveying roller 112 is also swingably mounted on the base 13. Specifically, a second mounting shaft 142 is provided on the base 13, and the matching manner of the second mounting shaft 142 and the base 13 has been mentioned above and will not be repeated here. The fourth gear 24 is arranged on the second mounting shaft 142. Optionally, unlike the first mounting shaft 141, the second mounting shaft 142 can be fixed on the mounting plate after installation, and the fourth gear 24 is rotatably arranged on the second mounting shaft 142. Alternatively, the second mounting shaft 142 can be rotatably arranged on the mounting plate like the first mounting shaft 141, and the fourth gear 24 is fixed on the second mounting shaft 142. The second bracket 152 is rotatably connected to the second mounting shaft 142 through a hole provided on the second bracket 152. A second rotating shaft 162 rotatable on the second bracket 152 is provided at one end of the second bracket 152. The second gear 22 and the second conveying roller 112 are both fixed on the second rotating shaft 162, so that when the second gear 22 rotates, the second conveying roller 112 can be driven to rotate through the second rotating shaft 162. The second telescopic unit 32 is also rotatably connected to the end of the second bracket 152 away from the end provided with the second rotating shaft 162 at one end, and rotatably connected to the base 13 at the other end, so as to control the second bracket 152 to swing on the base 13.

[0080] Moreover, in this embodiment, when the second bracket 152 is swinging, the second gear 22 rotates around the axis of the fourth gear 24. That is to say, when the second bracket 152 is swinging, the second gear 22 and the fourth gear 24 can always remain engaged, so that no matter how the second bracket 152 swings, the fourth gear 24 can drive the second gear 22 to rotate.

[0081] In this embodiment, the structure of the second bracket 152 is the same as that of the first bracket 151 , and the distance between the two plates of the second bracket 152 can be fixed by setting structures such as sleeves on the second mounting shaft 142 and the first rotating shaft 161 .
