Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, 2 and 3, fig. 1 is a schematic view showing the connection between a curved roll and a power source according to an embodiment of the present invention. Fig. 2 is a schematic structural view of an embodiment of a curved roll of the present invention. FIG. 3 is an enlarged schematic view of the transmission member of FIG. 2.
The invention provides an arc-shaped roller which comprises a roller shaft 10, a rubber roller 20 and a transmission piece 30.
The roll shaft 10 has an arc shape, and the roll shaft 10 is generally made of a hard material, such as steel, aluminum alloy, or the like. The roll shaft 10 is used for providing support for a rubber roll 20 sleeved outside the roll shaft. A holder 40 is provided at each end of the roll shaft 10 for fixing the curved roll to a base (not shown). In other embodiments, the support 40 is also provided with other adjustment mechanisms for adjusting the position of the curved roll.
The rubber roller 20 is sleeved outside the roller shaft 10. The glue roller 20 is typically a soft material, such as plastic, rubber, so that the glue roller 20 can rotate outside the roller 10. Of course, the rubber roller 20 may also be a composite material of these soft materials to increase the service life of the rubber roller 20, for example, the inner layer is plastic and the outer layer is rubber.
It can be understood that, in order to prevent the substrate from being damaged by the rubber roller 20 when the substrate passes through the arc roller, the rubber roller 20 is usually set to be smoother, and certainly, in order to further reduce the influence of the rubber roller 20 on the substrate, so that the rubber roller 20 rotates more flexibly outside the arbor 10, and prevent the rubber roller 20 from being distorted during the rotation process, the bearing 50 is usually set between the rubber roller 20 and the arbor 10.
In other embodiments, when the curved roller is long, when the power source 60 is disposed at one end of the rubber roller 20, the other end of the rubber roller 20 is kept in a stationary state due to inertia, so that the rubber roller 20 is very easily distorted. In addition, when the arc of the arc roller is large, the arc arch part has large resistance to the rotation of the rubber roller 20, so that the rubber roller 20 is easy to distort or deform, or the rubber roller 20 is twisted and then suddenly and suddenly slowed down under the action of restoring elasticity. Under the above circumstances, the rubber roll 20 can be set into multiple sections, and the sections are rigidly connected with each other, so that the rubber roll 20 is prevented from being distorted and deformed due to the self-transmission force, and the distance between the sections can be flexibly set according to the actual situation.
The transmission member 30 is used for receiving power provided by the power source 60 and driving the rubber roller 20 to rotate. In particular, the transmission member 30 comprises a first transmission member 31 and a second transmission member 32.
The first transmission 31 has a cylindrical shape, that is, the cross section of the first transmission 31 in the direction perpendicular to the axial direction of the roller shaft 10 is annular. The first transmission member 31 is connected, specifically fixedly connected, with the rubber roller 20, and is used for driving the rubber roller 20 to rotate.
The first transmission member 31 includes a first inner surface 311 and a first outer surface 312, the first inner surface 311 is a surface close to the roller shaft 10, and the first outer surface 312 is a surface far from the roller shaft 10. In the axial direction along the first transmission piece 311, the first outer surface 312 is a cambered surface.
Specifically, in the axial direction along the first transmission member 31, the first transmission member 31 includes two end portions, one end away from the end portion of the roller shaft 10 is an inner end 316, and the rubber roller 20 is connected to the inner end 316 of the first transmission member 31, or the rubber roller 20 is connected to the first inner surface 311. It is understood that the fixed connection may be at least one of gluing, screws or bolts to fix the first transmission member 31 and the rubber roller 20.
The second transmission member 32 is cylindrical and is sleeved outside the first transmission member 31, and the second transmission member 32 includes a second inner surface 321 and a second outer surface 322, wherein the second inner surface 321 is a surface close to the first outer surface 312, and the second outer surface 322 is a surface far from the first outer surface 312. The second inner surface 321 is in friction contact with the first outer surface 312, so that the rotation of the second transmission member 32 can drive the first transmission member 31 to rotate. In the axial direction of the second transmission member 32, the second inner surface 321 has an arc surface matching with the first outer surface 312, and the length of the second inner surface 321 is smaller than the length of the first outer surface 312, so that the second transmission member 32 slides relative to the first outer surface 312 in the axial direction, and the second outer surface 322 is connected with the power source 60, so that the second transmission member 32 drives the first transmission member 31 to rotate in the circumferential direction.
The second transmission member 32 is connected to the power source 60 through a connecting member 61, and the power source 60 transmits the driving force to the second transmission member 32 through the connecting member 61.
It will be appreciated that the transmission member 30 is typically configured in a belt or gear configuration to better receive the driving force from the power source 60, although the transmission member 30 may be other transmission member configurations commonly used in the art. The transmission member 30 in this embodiment is a pulley, the power source 60 is a motor, and the connecting member 61 is a belt. The motor transmits the driving force to the belt pulley through the belt, and the belt pulley drives the rubber roller 20 to rotate. Of course, the power source 60 may be other power machines such as a conventional internal combustion engine, an aerodynamic machine, a hydraulic power machine, and the like.
Different from the prior art, the first transmission piece 31 connected with the rubber roller 20 and the second transmission piece 32 connected with the power source 60 are arranged at one end of the arc-shaped roller, the contact surface between the first transmission piece 31 and the second transmission piece 32 is set to be the arc surface, and the length of the second transmission piece 32 is smaller than that of the first transmission piece 31 in the axial direction of the roller shaft 10, so that when the second transmission piece 32 rotates and is stressed along the axial direction of the second transmission piece 32, the second transmission piece 32 can slide along the axial direction of the roller shaft 10 relative to the first transmission piece 31, and therefore, the power source 60 or the connecting piece 61 such as a belt or a gear and the like cannot be damaged due to unilateral friction stress caused by the swinging of the arc-shaped roller.
Referring to fig. 4, fig. 4 is a schematic cross-sectional view taken along a-a direction in fig. 2.
Specifically, in this embodiment, the second inner surface 321 is provided with convex teeth 323 protruding inward at intervals, the length direction of the convex teeth 323 is parallel to the axial direction of the second transmission member 32, and the top surfaces of the convex teeth 323 are arc surfaces matched with the first outer surface 312, so that the convex teeth 323 slide on the arc surfaces of the first outer surface 312. It is understood that the convex tooth 323 has a plurality to keep the second transmission member 32 and the first transmission member 31 stable.
In addition, the first outer surface 312 is spaced apart to define a recess 313 that mates with the tooth 323, such that the tooth 323 is received within the recess 313 when installed. The groove 313 is matched with the convex tooth 323, namely the groove 313 is also an arc surface in the axial direction of the first transmission member 31, and the convex tooth 323 is accommodated in the groove 313, so that the second transmission member 32 can more stably drive the first transmission member 31 to rotate when rotating around the axis, and the second transmission member 32 can still move along the arc surface of the first transmission member 31 in the extending direction of the axis. Specifically, when the second transmission member 32 rotates along its axis and is stressed in the direction of extending the axis, due to the interaction between the convex teeth 323 and the concave grooves 313, the second transmission member 32 can swing to a proper position, so that the second transmission member 32 is automatically parallel to the axis of the power source 60 or the connecting member 61 of the power source 60 and the second transmission member 32, such as a belt or a gear, and the single-sided stress is prevented.
It can be understood that a boss 314 is arranged between two adjacent grooves 313, as shown in fig. 5, and fig. 5 is a structural schematic diagram of the boss embodiment in fig. 4. The cross section of the convex tooth 323 is rectangular, if the cross section of the boss 314 is also rectangular, the first transmission member 31 and the second transmission member 32 are easy to slide along the arc surface because there is no gap between the convex tooth 323 and the boss 314 or the gap is not enough during the rotation process, therefore, the boss 314 is set to be in the shape of a crowned tooth, so that a gap is formed between the side wall of the boss 314 and the side wall of the convex tooth 323, and the second transmission member 32 can slide flexibly and smoothly. Of course, the boss 314 may be formed to have a rectangular cross section and the convex teeth 323 may be formed as crown teeth, or both the boss 314 and the convex teeth 323 may be formed as crown teeth.
With reference to fig. 2 and fig. 3, in the axial direction of the first transmission member 31, the first outer surface 312 is an outwardly convex arc surface, i.e. an arc surface with a high middle and low ends. In this embodiment, in the axial direction of the first transmission member 31, the first transmission member 31 includes an outer end 315 close to the end of the roller shaft 10 and an inner end 316 far from the end of the roller shaft, the outer end 315 of the first transmission member 31 is provided with a stopper 317, and the height of the stopper 317 is higher than the highest point of the arc shape of the first transmission member 31, so that the second transmission member 32 can be prevented from being separated from the first transmission member 31 due to an excessively large swing amplitude during the sliding process.
Referring to fig. 6, fig. 6 is a schematic structural view of another embodiment of a curved roll of the present invention.
In the present embodiment, in the axial direction along the first transmission member 31, the first outer surface 312 is an inwardly concave arc surface, i.e., an arc surface with a low middle and high ends. In order to facilitate the installation of the second transmission member 32 in a suitable position on the first transmission member 31, the first transmission member 31 includes a first portion 318 and a second portion 319 which are independent of each other, and the first portion 318 and the second portion 319 are symmetrical to each other. For example, the first portion 318 has a recess, the second portion 319 has a recess, and the recesses of the first portion 318 and the second portion 319 form a complete recess region, i.e. an inwardly recessed arc. When the transmission member 32 is installed, the first portion 318 is installed, the second transmission member 32 is installed in the recess of the first portion 318, and then the second portion 319 is installed, so that the second transmission member 32 is sleeved outside the first transmission member 31.
In other embodiments, a lubrication system may be further disposed between the first transmission member 31 and the second transmission member 32, for example, adding lubricating oil, so that the second transmission member 32 can flexibly slide along the arc surface of the first transmission member 31.
In other embodiments, a control system and a force application component may be further provided for actively adjusting the swing angle and the swing position of the second transmission member 32, so that the second transmission member 32 can be located at a suitable position on the first transmission member 31, thereby preventing the second transmission member 32 from unilateral friction with a power source or a connecting member of the power source, such as a belt.
In conclusion, the present invention can prevent the power source 60 or the connecting member 61 such as a belt or a gear from generating a single-side friction force due to the swing of the arc roller, thereby preventing the power source 60 or the connecting member 61 such as a belt or a gear from being damaged.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
