The roller 200 is a core member of the conveyor to prevent the conveyor belt 300 from deviating. The roller 200 includes a support rod 210 and a roller body 220, the second side wall 120 is provided with a dismounting hole 121, the dismounting hole 121 is communicated with the surrounding space, a first end of the support rod 210 can penetrate into the surrounding space from the dismounting hole 121 and is detachably connected with the first side wall 110, a second end of the support rod 210 is detachably connected with the second side wall 120, and the roller body 220 is rotatably sleeved on the support rod 210 and is in rolling contact with the conveying belt 300. That is, the supporting rod 210 and the roller body 220 are installed in the surrounding space, the roller 200 is detachably connected with the frame 100 through the supporting rod 210, and the roller body 220 is in rolling contact with the conveyor belt 300, so that under the condition that the conveyor belt 300 works normally, a small friction force exists between the roller body 220 and the conveyor belt 300, the obstruction of the roller body 220 to the conveyor belt 300 is reduced, the power consumption of the conveyor belt 300 when the conveyor belt 300 is not deviated is further reduced, the abrasion to the conveyor belt 300 is reduced, and the service life of the conveyor belt 300 is prolonged.

Meanwhile, the supporting rod 210 can drive the roller body 220 to move, so that the correction is performed on the conveyor belt 300 through the roller body 220, that is, the roller body 220 can be driven to move through adjusting the supporting rod 210, so that the correction is performed on the conveyor belt 300 with the deviation. In addition, the first end portion of the support rod 210 and the second end portion of the support rod 210 may be respectively connected to the first sidewall 110 and the second sidewall 120 by means of a fastening connection or a threaded connection, and the roller body 220 may be rotatably sleeved on the support rod 210 by means of a rolling bearing, which is not limited in the embodiment of the present utility model.

In a specific operation process, when the roller 200 is installed, the roller body 220 is sleeved on the support rod 210, and then the first end of the support rod 210 is inserted into the surrounding space from the dismounting hole 121, that is, the support rod 210 and the roller body 220 can be inserted into the surrounding space through the dismounting hole 121 on the side of the frame 100, the first end of the support rod 210 in the surrounding space is connected with the first side wall 110, and meanwhile, the second end of the support rod 210 is installed on the second side wall 120, so that the roller 200 is detachably connected with the frame 100 through the support rod 210. When the roller 200 is disassembled, the first end of the support bar 210 is disassembled from the first side wall 110, and the second end of the support bar 210 is simultaneously disassembled from the second side wall 120, so that the support bar 210 and the roller body 220 can be taken out from the surrounding space through the disassembly holes 121, thereby realizing the disassembly of the roller 200.

According to the transmission device disclosed by the embodiment of the utility model, through improving the structure of the transmission device related to the related art, the disassembly and assembly holes 121 are formed in the second side wall 120 of the stand 100, so that the support rod 210 and the roller body 220 sleeved on the support rod 210 can enter the surrounding space through the disassembly and assembly holes 121, and the roller 200 is installed by detachably connecting the first end part and the second end part of the support rod 210 with the first side wall 110 and the second side wall 120 respectively, in this case, the first end part and the second end part of the support rod 210 are detached from the first side wall 110 and the second side wall 120 respectively, and then the support rod 210 and the roller body 220 sleeved on the support rod 210 are taken out from the surrounding space through the disassembly and assembly holes 121, so that the roller 200 can be detached. According to the structure, the roller body 220 in rolling contact with the conveying belt 300 can be driven to move through the adjusting support rods 210, so that the conveying belt 300 is corrected, the roller 200 can be disassembled and assembled without disassembling the whole conveying device, the roller 200 is easier to replace, and the conveying device is convenient to maintain.

In a further embodiment, the frame 100 may further include a guide rail 140, the extending direction of the guide rail 140 may be perpendicular to the direction of the conveying objects of the conveying belt 300, the guide rail 140 may be disposed opposite to the mounting hole 121, and the guide rail 140 may be used for guiding and sliding fit with the support bar 210 or the roller body 220. That is, the extending direction of the guide rail 140 is parallel to the extending direction of the roller 200 after being mounted on the frame 100, and the guide rail 140 is not dislocated from the mounting and dismounting hole 121, so that the roller 200 can extend into the surrounding space through the mounting and dismounting hole 121, at this time, the support bar 210 or the roller body 220 can contact with the guide rail 140 and can slide on the guide rail 140, so that the guide rail 140 can guide the movement of the support bar 210 or the roller body 220 in the surrounding space, thereby achieving the purpose of guiding the mounting of the roller 200.

Specifically, when the roller 200 enters the surrounding space, the roller 200 passes through the dismounting hole 121, and the support rod 210 or the roller body 220 slides along the guide rail 140, so that the first end of the support rod 210 can relatively accurately reach the vicinity of the installation position on the first side wall 110, and the support rod 210 is prevented from deflecting in the process of penetrating into the surrounding space and deviating from the installation position on the first side wall 110, so that the installation of the roller 200 can be guided, and the roller 200 is easy to install.

In a possible solution, the two ends of the guide rail 140 may be fixedly connected to the first side wall 110 and the second side wall 120, respectively, in which case the guide rail 140 is closer to the mounting position of the support rod 210 on the first side wall 110, so that the guide rail can more effectively guide the first end of the support rod 210 to the vicinity of the mounting position on the first side wall 110. In addition, both ends of the guide rail 140 may be fixedly coupled to the first and second sidewalls 110 and 120, respectively, by welding or screwing, to which the embodiment of the present utility model is not limited.

Of course, in another possible embodiment, the frame 100 may further include a bottom support plate 130, the bottom support plate 130 may be fixedly connected to the first sidewall 110 and the second sidewall 120, and the guide rail 140 may be fixedly connected to the bottom support plate 130. With this structure, the guide rail 140 is supported by the bottom support plate 130, so as to avoid deformation of the guide rail 140 when being stressed, and improve stability of the guide rail 140, thereby ensuring more reliable guiding of the guide rail 140. Specifically, the first sidewall 110 and the second sidewall 120 may be fixedly coupled to the bottom support plate 130 by welding or screwing, and the guide rail 140 may be fixed to the bottom support plate 130 by welding or screwing, which is not limited in this regard.

In a further embodiment, the conveying device may further include a slider 400, the slider 400 may include a first bar hole 420, the slider 400 may be disposed at a first end of the support rod 210 through the first bar hole 420, that is, the first end of the support rod 210 penetrates into the first bar hole 420, so that the slider 400 is installed at the first end of the support rod 210, and the slider 400 may be clamped and fixed between the first end of the support rod 210 and the first side wall 110, that is, when the first end of the roller 200 is installed at the first side wall 110, the slider 400 is clamped and fixed between the first end of the roller 200 and the first side wall 110.

In the case that the first end of the support bar 210 is penetrated into the surrounding space from the mounting/dismounting hole 121, the slider 400 may slide on the guide rail 140, i.e., the support bar 210 is indirectly contacted with the guide rail through the slider 400, thereby guiding the mounting of the support bar 210 by the slider 400 sliding on the guide rail 140. Because the slider 400 has a certain width, the slider 400 is not easy to deviate in the guide rail 140, and the deflection of the support rod 210 when penetrating into the surrounding space is avoided, so that the first end of the support rod 210 can be more accurately guided to the vicinity of the installation position on the first side wall 110, and meanwhile, the slider 400 is easy to raise the first end of the roller 200, so that the first end of the support rod 210 is closer to the installation position on the first side wall 110, and the installation of the support rod 210 is more facilitated. In addition, the sliding block 400 is in sliding contact with the guide rail 140, so that the first end of the support rod 210 is prevented from being worn, and the service life of the support rod 210 is prolonged.

In a preferred embodiment, the slider 400 may further include an arc-shaped protrusion 410, and the arc-shaped protrusion 410 may be in sliding contact with the guide rail 140 when the first end of the support rod 210 is inserted into the surrounding space from the mounting/dismounting hole 121. With such a structure, the contact area between the slider 400 and the guide rail 140 is small, so that the friction between the slider 400 and the guide rail 140 can be reduced, and the slider 400 can slide on the guide rail 140 more smoothly.

Of course, the number of the arc-shaped protrusions 410 may be one or more. An arc-shaped protrusion 410 can reduce the contact area between the slider 400 and the guide rail 140 as much as possible, thereby reducing the friction between the slider 400 and the guide rail 140 and ensuring smooth sliding of the slider 400. The plurality of arc-shaped protrusions 410 can prevent the slider 400 from swinging in the guide rail 140, so that the first end of the support rod 210 can be prevented from deviating from the installation position on the first side wall 110, and the support rod 210 can be installed conveniently. The specific number of arcuate projections 410 is not limited by embodiments of the present utility model.

In an embodiment of the present utility model, the stand 100 may include a mounting plate 150, where the mounting plate 150 may be detachably covered on the dismounting hole 121, so as to avoid that impurities with a larger volume enter the surrounding space from the dismounting hole 121, which may affect the normal installation of the roller 200 or cause the conveyer belt 300 to be jammed. In addition, the mounting plate 150 may have a second bar-shaped hole 151, and the second end of the support bar 210 may be movably disposed in the second bar-shaped hole 151, so that when the conveyor belt 300 is deviated, the adjustment of the roller 200 can be achieved by adjusting the second end of the support bar 210, thereby changing the specific contact condition between the roller 200 and the conveyor belt 300 to adjust the deviated conveyor belt 300.

Based on this, in one possible embodiment, the second bar hole 151 may include a first horizontal bar hole in which the second end of the support bar 210 may be movably disposed to change the direction of the frictional force between the conveyor belt 300 and the roller body 220 by moving the second end of the support bar 210. In this structure, the second end of the supporting rod 210 moves in the first horizontal bar hole, so that the central axis of the supporting rod 210 is inclined with respect to the width direction of the conveying belt 300, so that the direction of the friction force applied to the conveying belt 300 by the roller body 220 is changed, and the conveying belt 300 is subjected to a deviation adjusting force along the width direction (the deviation adjusting force is a component force of the friction force applied to the conveying belt 300 by the roller body 220 in the width direction of the conveying belt 300), so that the conveying belt 300 can deviate under the action of the deviation adjusting force, and it is noted that the width direction of the conveying belt 300 is perpendicular to the direction in which the conveying belt 300 conveys objects. In a specific working process, the second end of the support rod 210 is moved, so that the central axis of the roller body 220 is inclined relative to the width direction of the conveying belt 300, and the direction of the deviation adjusting force applied to the conveying belt 300 is opposite to the deviation adjusting direction, so that the deviation adjusting conveying belt 300 can be adjusted.

In another possible embodiment, the second bar hole 151 may include a first vertical bar hole in which the second end of the support bar 210 may be movably disposed to change the height of the second end of the roller body 220 by adjusting the height of the second end of the support bar 210, thereby changing the pressure difference across the conveyor belt 300. Specifically, the second end of the support rod 210 moves up or down in the first vertical bar hole, so that the pressure of the conveyor belt 300 near the second end of the roller body 220 increases or decreases, and the conveyor belt 300 near the second end of the roller body 220 is tensioned or relaxed, so that the friction force applied to the conveyor belt 300 by the roller body 220 is in an increasing or decreasing trend along the direction from the first end of the roller body 220 to the second end of the roller body 220, wherein the friction force applied by the roller body 220 on the tensioned side of the conveyor belt 300 is greater than the friction force applied by the roller body 220 on the relaxed side thereof, so that the conveyor belt 300 is deflected to the relaxed side, and the purpose of adjusting the deflected conveyor belt 300 is achieved.

Of course, in other embodiments, the second bar hole 151 may include a first horizontal bar hole and a first vertical bar hole, which may communicate with each other and be perpendicular, and the second end of the support bar 210 may be movably disposed in the first horizontal bar hole or the first vertical bar hole. With this structure, the direction of the frictional force between the conveyor belt 300 and the roller body 220 can be changed by moving the second end portion of the support bar 210, and the pressure difference across the conveyor belt 300 can be changed by adjusting the height of the second end portion of the support bar 210. Under such a situation, the deviation of the conveyor belt 300 can be corrected in two ways, so that the situation that the deviation cannot be corrected normally when the first horizontal bar hole or the first vertical bar hole fails can be avoided, and the reliability of the conveying and conveying device is improved.

In a further aspect, the first end of the support rod 210 may be connected to the first sidewall 110 through the second screw 800. Wherein the second end of the support bar 210 can swing around the first end thereof when the second end of the support bar 210 moves in the second bar-shaped hole 151. In addition, the sliding block 400 can be fixed on the first side wall 110 in a threaded connection or clamping manner, so that the sliding block 400 is prevented from loosening to influence the normal swing of the supporting rod 210, the supporting rod 210 is prevented from being influenced to drive the roller body 220 to move, and the roller body 220 is prevented from being influenced to rectify the deviation of the conveying belt 300.

To facilitate the swinging of the support bar 210 around its first end, the tightness of the second screw 800 may be adjusted according to the actual requirements. Specifically, in the case of the conveyor belt 300 being deviated, the second screw 800 may be unscrewed, so that the first end of the support bar 210 may perform a certain movement, thereby preventing the support bar 210 from being blocked when swinging around the first end thereof, and further facilitating the swinging of the support bar 210, so that the adjustment of the roller body 220 is easier to be achieved. In the case that the conveyor belt 300 is operating normally, the second screw 800 may be screwed, thereby achieving the fixation of the first end of the support bar 210, and avoiding the first end of the support bar 210 from loosening to affect the roller body 220.

In a more preferred technical solution, the first end of the support rod 210 may be provided with a step plane 230, the step plane 230 may be in spacing contact with the first bar hole 420 in the circumferential direction of the support rod 210, so as to avoid rotation of the support rod 210 relative to the roller body 220 caused by rotation of the support rod 210, and avoid slipping of the roller body 220, which makes it difficult to rectify the deviation of the conveyor belt 300, and in addition, abrasion caused by rotation of the first end of the support rod 210 can be avoided, which is beneficial to prolonging the service life of the support rod 210.

Of course, the second end of the support rod 210 may include a step plane 230, where the step plane 230 may be in limited contact with the second bar hole 151 in the circumferential direction of the support rod 210, so as to avoid rotation of the second end of the support rod 210 in the second bar hole 151, thereby further avoiding rotation of the support rod 210 relative to the roller body 220, avoiding slipping of the roller body 220, and avoiding abrasion caused by rotation of the second end of the support rod 210, which is beneficial to further prolonging the service life of the support rod 210.

In an embodiment of the present utility model, the transmission device may further include a deviation adjusting block 600, the deviation adjusting block 600 may be detachably connected to the second end of the support rod 210 through the first screw 700, and the first screw 700 may be in the first state or the second state by adjusting the tightness of the first screw 700. Specifically, in the case where the first screw 700 is in the first state, the deviation adjusting block 600 may be fixed to the second end of the support rod 210, and the mounting plate 150 may be clamped between the deviation adjusting block 600 and the second end of the support rod 210, at which time the second end of the support rod 210 is fixed. In the case that the first screw 700 is in the second state, there is an installation gap between the deviation adjusting block 600 and the installation plate 150, that is, the first screw 700 in the second state is unscrewed, at this time, the second end of the support rod 210 may be driven to move in the second bar-shaped hole 151 by pulling the deviation adjusting block 600, and the second end of the support rod 210 may be moved more easily by setting the deviation adjusting block 600.

In a specific working process, under the condition that the conveyer belt 300 is in normal working, the conveyer belt 300 is not deviated, at this time, the first screw 700 is in the first state, so as to avoid that the second end of the supporting rod 210 moves in the second bar-shaped hole 151, and the supporting rod 210 drives the roller body 220 to swing around the first end of the supporting rod 210, thereby causing the deviation of the conveyer belt 300 and avoiding affecting the normal working of the conveyer belt 300. In the case that the conveyor belt 300 is in the off tracking state, the first screw 700 is adjusted to the second state so that the second end of the support bar 210 can move in the second bar-shaped hole 151, thereby enabling the off tracking conveyor belt 300 to be adjusted by pulling the deviation adjusting block 600. The structure can adjust the connection state of the first screw 700 according to the working state of the conveyer belt 300, unscrew the first screw 700 to adjust the conveyer belt 300 with deviation when the conveyer belt 300 deviates, screw the first screw 700 after adjusting the conveyer belt 300, thereby avoiding the influence of the roller body 220 on the normal work of the conveyer belt 300 when the conveyer belt 300 does not deviate, and being beneficial to improving the working stability of the conveyer belt 300.

In the embodiment of the present utility model, the rollers 200 may be one, and one roller 200 can adjust the conveyor belt 300, and save production materials. The number of rollers 200 may be plural, in which case, when some of the rollers 200 fail, the remaining normal rollers 200 can still adjust the conveyor belt 300 that is deviated, which is beneficial to improving the stability of the conveying device. In addition, the first side wall 110 may be provided with the dismounting hole 121, so that the second ends of the rollers 200 can be respectively disposed on the first side wall 110 and the second side wall 120 through the mounting plate 150, and the user can adjust the off-tracking conveyor belt 300 on two sides of the conveying device, thereby being more convenient to adjust.

In a more preferred technical solution, the offset adjusting block 600 may include an adjusting rod 610, the adjusting rod 610 may be fixedly connected with the offset adjusting block 600, and the central axis of the adjusting rod 610 may be parallel to the extending direction of the second side wall 120, and the offset adjusting block 600 may be driven to move by pushing and pulling the adjusting rod 610, so as to drive the second end of the supporting rod 210 to move in the second bar hole 151. The adjusting rod 610 facilitates the grasping of the user, thereby facilitating the force application of the user, further facilitating the movement of the second end portion of the supporting rod 210, and the central axis of the adjusting rod 610 is parallel to the extending direction of the second side wall 120, thereby avoiding the user from doing idle work, saving the user more effort, and facilitating the adjustment. In addition, the adjusting lever 610 may be further provided with a protrusion 611 to prevent slipping when the user grasps the device, thereby further facilitating adjustment.

In a further technical solution, the mounting plate 150 may be disposed in the surrounding space, so that the mounting plate 150 is mounted in the mounting hole 121 and is recessed in the surrounding space, thereby preventing the deviation adjusting block 600 and the adjusting rod 610 from being mistakenly touched, affecting the connection state of the first screw 700, preventing the first screw 700 from loosening, and preventing the supporting rod 210 from rotating and swinging, thereby affecting the normal operation of the conveying belt 300.
