Description

Technical Field

[0001] The present application relates to the field of transportation technology, and in particular to a deviation-correcting roller. Background Art

[0002] Roller conveyors consist of a drive unit, transmission system, control system, rollers, frame, and legs. They move items forward through friction between the rotating rollers and the items. During roller conveying, the conveyor belt or the items being conveyed on the rollers often shift, preventing them from reaching their intended location and impacting subsequent operations.

[0003] For example, a Chinese patent document (publication number: CN 205312397 U) provides a correction roller comprising a roller body comprising a fixed shaft and a tubular body sleeved on the fixed shaft. The tubular body is composed of two symmetrical halves about its axis: a fixed half, rotatably connected to the fixed shaft, and a movable half, fixedly connected to the fixed shaft. The fixed shaft is connected to a drive mechanism that drives the fixed shaft to reciprocate along its axis. Because this device only uses one axially movable half for correction, its correction effect is poor.

[0004] For example, a Chinese patent document (publication number: CN 204433612 U) provides a roller assembly for correcting the deviation of a transmission belt. The roller assembly includes a roller, which is composed of one or more sliding rollers and at least one static roller and has a multi-segment ring structure in cross section. Each sliding roller is suitable for axial movement relative to the static roller, and the sliding roller and the static roller are suitable for rotating together around the central axis. The roller drive shaft is connected to the fixed shaft by a spring, so that the fixed shaft can move axially. The static roller is fixedly mounted on the support sleeve of the drive shaft. The two sliding rollers can rotate with the fixed shaft and move axially through the balance of spring force. However, since the drive shaft and the fixed shaft are connected and transmitted by a spring, if the transported goods are heavy, there will be slippage. The spring is also prone to fatigue after long-term use. Not only is it inconvenient to repair and replace, but it also seriously affects the deviation correction effect.

[0005] At the same time, when the above-mentioned device corrects the deviation of the fabric, the fabric is very likely to wrinkle, and the user will need to deal with the wrinkles later, delaying the production progress.

[0006] To address the above problems, no effective solutions have been proposed in the relevant technologies. Summary of the Invention

[0007] The main purpose of the present application is to provide a correction roller to solve the problem in the related art that wrinkles are easily generated when the roller corrects the cloth.

[0008] In order to achieve the above objectives, according to one aspect of the present application, a correction roller is provided.

[0009] The correcting roller according to the present application includes a fixed shaft, which defines a central axis; rollers, which are arranged circumferentially along the fixed shaft and can rotate around the central axis to transmit materials; it is characterized in that it also includes: a drive disk, which includes an inner ring and an outer ring with concentric centers, the inner ring is rotatably connected to the inside of the outer ring, the outer ring is circumferentially movably connected to the roller and can rotate around the central axis with the roller; a radial rotating shaft, the radial rotating shaft defines a radial axis, and the radial axis is perpendicular to the central axis; wherein, the inner ring is movably connected to the fixed shaft through the radial rotating shaft, and the drive disk can rotate around the radial axis to make the roller move along the central axis.

[0010] Furthermore, a plurality of connecting columns are arranged circumferentially on the outer ring, and the roller strips are connected to the connecting columns via spherical bearings.

[0011] Furthermore, the radial rotating shaft is fixedly connected to the inner wall of the inner ring, and one end of the fixed shaft is provided with a radial hole for installing the radial rotating shaft.

[0012] Furthermore, the radial rotating shaft is fixedly connected to one end of the fixed shaft, and the inner wall of the inner ring is provided with a radial hole for installing the radial rotating shaft.

[0013] Furthermore, a rotating shaft is rotatably mounted on the outer periphery of the fixed shaft via a bearing, and the roller is slidably connected to the rotating shaft and can rotate around the central axis along with the rotating shaft.

[0014] Furthermore, a plurality of guide rails are arranged along the circumferential direction of the outer periphery of the rotating shaft, and the guide rails are parallel to the central axis; the guide rails are slidably connected to a plurality of sliders, and the rollers are fixedly connected to the sliders so that the rollers slide relative to the guide rails.

[0015] Furthermore, the guide rails are arranged in groups of two, and each group of guide rails is connected with a plurality of sliders along the length direction.

[0016] Furthermore, it also includes a sensing device, which is arranged at both ends of the correction roller, and the sensing device is electrically connected to the controller.

[0017] Furthermore, it also includes an electric push rod, the telescopic end of which is movably connected to the position of the inner ring away from the radial axis, for providing a force for the drive disk to rotate around the radial axis.

[0018] Furthermore, one end of the rotating shaft is fixedly connected to a gear, and the gear is connected to the motor through a transmission belt to rotate the rotating shaft.

[0019] More specifically, some embodiments of the present application may produce the following specific beneficial effects:

[0020] The deviation correction roller of the present application also includes a drive disc and a radial rotating shaft. The drive disc includes a concentric outer ring and an inner ring. The inner ring is rotatably connected to the inside of the outer ring. The outer ring is circumferentially connected to the roller and can rotate with the roller around the central axis. The radial rotating shaft defines the radial axis, which is perpendicular to the central axis. The inner ring is movably connected to the fixed shaft through the radial rotating shaft, and the drive disc can rotate around the radial axis to move the roller along the central axis. The structure of this device is simplified, and the roller rotates and moves through the fixed central axis and radial rotating shaft, which greatly enhances the stability of material transmission and deviation correction. When the drive disc rotates around the radial axis, the roller can move along the central axis. The farther the roller on the drive disc is from the radial axis, the greater the displacement, and vice versa. Therefore, the movement of the roller has a certain hierarchy, the displacement between adjacent rollers is small, and the transition is smoother. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Reference Figure 1 As shown, the deviation-correcting roller in this embodiment includes a plurality of circumferentially arranged roller strips 100 , a fixed shaft 300 , and a rotating shaft 400 .

[0046] The two ends of the fixed shaft 300 are fixed to the base 310, and the fixed shaft 300 defines the central axis 200 and plays a role in stable support. Figure 1 As shown, a rotating shaft 400 is rotatably mounted on the outer periphery of the fixed shaft 300 through a bearing, and the roller 100 is slidingly connected to the rotating shaft 400 and can rotate around the central axis 200 along with the rotating shaft 400. The central axis 200 coincides with the axis of the fixed shaft 300. The rollers 100 are combined to form a cylindrical outer surface, and the rollers 100 can rotate around the central axis 200 to transmit materials.

[0047] Several guide rails 410 are arranged circumferentially around the rotating shaft 400, parallel to the central axis 200. Several sliders 420 are slidably connected to the guide rails 410, and the rollers 100 are fixedly connected to the sliders 420, allowing them to slide relative to the guide rails 410. That is, the rollers 100 can slide along the central axis 200, and when the rotating shaft rotates, the rollers 100 rotate accordingly, and the surface of the rollers 100 rubs against the material, thereby transporting the material.

[0048] In some examples, a plurality of annular grooves are formed on the surface of the rotating shaft 400 , and the guide rail 410 is disposed in the annular grooves to save space, and the annular grooves further limit the displacement of the slider 420 .

[0049] In some examples, such as Figure 2 As shown, a plurality of limiting rings 430 are mounted on the surface of the rotating shaft 400 , and both ends of the guide rail 410 are fixedly connected to the limiting rings 430 .

[0050] Specifically, if Figure 3As shown, the guide rails 410 are arranged in pairs, and each group of guide rails 410 is connected with a plurality of sliders 420 along the length direction. That is, each column of sliders 420 is penetrated by two guide rails 410, so that the sliders 420 have a certain stability during the movement.

[0051] In some examples, 2 to 4 sliders 420 are slidably installed on each set of guide rails 410, and the guide rails 410 are arranged in 4 to 10 groups. Each set of guide rails 410 is installed with a roller 100, and the roller 100 on each set of guide rails can be divided into multiple fixedly connected sections.

[0052] like Figure 4 and Figure 5 As shown, to address the problem of wrinkles easily generated when using rollers to correct fabric deflection in related art, the deflection correction roller of this embodiment further includes a drive disc 500 and a radial shaft 600. The drive disc 500 comprises a concentric outer ring 510 and an inner ring 520. The inner ring 520 is rotatably connected to the interior of the outer ring 510. The outer ring is circumferentially and movably connected to a roller bar 100 and can rotate along the central axis 200 with the roller bar 100. The radial shaft 600 defines a radial axis 610, which is perpendicular to the central axis 200. The inner ring 520 is movably connected to the fixed shaft 300 via the radial shaft 610. The drive disc 500 can rotate about the radial axis 610 to move the roller bar 100 along the central axis 200. Compared to related art, this device has a simplified structure, and the roller bar rotates and moves via the fixed central axis and radial shaft, greatly enhancing the stability of material transmission or deflection correction.

[0053] like Figure 1 As shown, the surface of the deviation-correcting roller in this embodiment is covered with rollers 100 that can rotate around the central axis 200 along with the rotating shaft 400. All rollers 100 are connected to the driving disk 500. When the driving disk 500 rotates around the radial axis 610, the rollers 100 can move stably along the central axis 200. The farther the rollers 100 on the driving disk 500 are from the radial axis 610, the greater the displacement, and vice versa. Therefore, the movement of the rollers 100 has a certain level of hierarchy, the displacement between adjacent rollers 100 is small, and the transition is smoother. The driving disk 500 rotates the conveyed material around the radial axis 600 according to the deviation of the material. The greater the deviation of the material, the greater the rotation amplitude of the driving disk 500. The surface of the roller 100 is in friction contact with the material. When the material deviates in a certain direction, the roller 100 in contact with the deviated part of the material can move in the opposite direction of the deviation and bring it back. In this process, the displacement of the end of the roller 100 is stepped, and the displacement between adjacent rollers 100 is small, the transition is smooth, and it is not easy to produce wrinkles when conveying cloth. The more rollers 100 there are, the more natural and smooth the transition is, and the less likely it is to produce wrinkles.

[0054] As a specific plan, Figure 5As shown, the inner ring 520 is rotatably connected to the outer ring 510 via a bearing. The outer ring 510 can rotate relative to the inner ring. The diameter of the inner ring 520 is smaller than that of the outer ring 510. As an alternative, the inner ring 520 and the outer ring 510 can be connected to the bearing via a retaining spring 530 or an interference fit. Figure 8 As shown, the inner ring 520 is clamped to the inner ring of the bearing through the inner retaining spring 531, and the outer ring 510 is clamped to the outer ring of the bearing through the outer retaining spring 532. The inner ring 520 and the outer ring 510 are respectively provided with retaining spring grooves for installing the retaining springs 530. The structure is simple and easy to assemble.

[0055] In some examples, one end of the fixed shaft 300 is fixedly connected to a radial rotating shaft 600, and the inner wall of the inner ring 520 is provided with a radial hole 320 for installing the radial rotating shaft 600. The driving disk 500 is clamped to the radial rotating shaft 600 and can rotate around the radial axis 610. The radial rotating shaft 600 passes through the radial hole 320 opened on the inner wall of the inner ring 520.

[0056] In some examples, such as Figure 6 、 Figure 7 and Figure 8 As shown, the inner wall of the inner ring 520 is fixedly connected with a radial rotating shaft 600 , and one end of the fixed shaft 300 is provided with a radial hole 320 for installing the radial rotating shaft 600 , and the radial rotating shaft 600 passes through the radial hole 320 .

[0057] like Figure 5 As shown, the outer ring 510 is circumferentially arranged with several connecting columns 511, and the number of the connecting columns 511 is consistent with the number of the rollers 100. The rollers 100 are connected to the connecting columns 511 through joint bearings to reduce the mechanical damage to the rollers 100 during rotation and sliding.

[0058] More specifically, if Figure 6 As shown, the roller 100 is movably connected to the connecting column 511 through a fisheye bearing. One end of the fisheye bearing is fixedly connected to the roller 100, and the other end is movably connected to the connecting column 511. A limit block 512 is provided at the top of the connecting column 511, and the fisheye bearing is located between the limit block 512 and the outer ring 510 to prevent the fisheye bearing from falling off the connecting column 511.

[0059] Among them, Figure 9As shown, to provide the drive disc 500 with a force to rotate about the radial axis 610, the inner ring 520 is connected to a drive mechanism at a position away from the radial axis 610. Specifically, the telescopic end of the electric push rod 700 is movably connected to the inner ring 520 at a position away from the radial axis 610. As a result, when the electric push rod 700 is extended or retracted, it drives the drive disc 500 to rotate, causing the roller 100 to move back and forth along the central axis 200. The extent of the electric push rod 700's extension or retraction depends on the degree of material deflection. To ensure that the electric push rod 700 provides the force to reciprocate the roller 100 along the central axis 200, the line of action of the electric push rod 700 must be parallel to the central axis 200.

[0060] Specifically, such as Figure 9 As shown, the telescopic end of the electric push rod 700 is connected to the driving disk 500 through the driving rod 710. The driving rod 710 extends the action point of the electric push rod 700 to the outside of the driving disk 500 to prevent the driving disk 500 and the electric push rod 700 from interfering with each other during movement. More specifically, as Figure 10 As shown, the drive rod 710 includes a fixed portion 711, an extension portion 712, and a connecting portion 713. The fixed portion 711 is constructed in a disc-like shape and is connected to the inner ring 520 and circumferentially fixed to the disk surface of the inner ring 520. The extension portion 712 is perpendicular to the central axis 200 along its length. One end of the extension portion is connected to the fixed portion 711, and the other end is connected to the connecting portion 713. The connecting portion 713 is formed with a connecting hole for mounting a hinge shaft 714. The connecting portion 713 is hinged to the end of the electric push rod 700 via a fisheye bearing. The hinge shaft 714 passes through the fisheye hole of the fisheye bearing and the connecting hole of the connecting portion 713 from bottom to top. When the electric push rod 700 is extended or retracted, the drive rod 710 and the retracted end of the electric push rod 700 rotate relative to each other. The electric push rod 700 applies a stable force to the drive disk 500 through the drive rod 710. In this embodiment, the drive plate 500 is formed into an inner and outer ring. The inner ring 520 is connected to the outer ring 510 via a bearing, so that the inner ring 520 is connected to the fixed central axis and cannot rotate circumferentially, but can rotate about the radial axis 610. The outer ring 510 is connected to the roller strip 100. In this way, the outer ring 510 and the roller strip 100 can rotate circumferentially and rotate along with the inner ring 520 about the radial axis 610.

[0061] As an optional solution, the correction rollers of this embodiment can serve as driven rollers. These rollers rotate due to friction with the fabric, which can cause wrinkles in the fabric. When the fabric deviates, the rollers 100 can correct the deviation by moving along the central axis 200, smoothing out the wrinkles. Because different fabrics have different materials, the friction they generate with the rollers also varies. If the friction between the fabric and the rollers is too low, using this solution may result in fabric transport failure and an inability to correct the deviation.

[0062] As another optional solution, the deviation correction roller of this embodiment can be used as an active roller. Figure 2 As shown, one end of the rotating shaft 400 is fixedly connected to a gear 820, and the gear 820 is connected to the motor 800 through a transmission belt 810. When the motor 800 is working, the motor 800 drives the gear 820 to rotate through the transmission belt 810, thereby rotating the rotating shaft 400, driving the roller 100 to rotate, thereby driving the cloth on the roller 100 to be transmitted, further reducing wrinkles on the cloth.

[0063] Among them, Figure 1 As shown, as an optional solution, sensing devices 900 are installed at both ends of the correction roller, and the sensing devices 900 are electrically connected to the controller. The sensing devices 900 detect the material conveyed on the roller and send a signal to the controller. The controller determines whether the material is deviated and controls the movement of the electric push rod 700 to correct the material.

[0064] As another option, the electric push rod can also be controlled by the user to correct the material according to the on-site conditions.

[0065] Furthermore, the terms "installed," "disposed," "provided with," "connected," "connected," and "socketed" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0066] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
