Description

Technical Field

[0001] This invention relates to the field of material conveying equipment technology, and in particular to a conveying device that facilitates the replacement of conveyor belts. Background Technology

[0002] Belt conveyors are widely used in industrial production conveying processes due to their large conveying capacity and stable transport. However, because the conveyor belt needs to be in direct contact with the materials and is often made of materials such as plastic, it often needs to be replaced after a period of operation.

[0003] Replacing belts on existing belt conveyors typically involves cutting and replacing the belt, heat-sealing the belt, or requiring workers to lift the entire conveyor and insert the belt. One of these methods is complex, and the other is unsuitable for installing wider conveyor belts with high rigidity and strength requirements.

[0004] A search revealed that Chinese patent CN208916017U, entitled "A quick-release conveyor device and material conveying system," discloses a device for installing or removing a belt from the side. The shortcoming of this patent is that when it is necessary to install or remove the belt, a base frame needs to be installed or removed from below the conveyor belt. Summary of the Invention

[0005] To address the technical problems existing in the background art, the present invention proposes a conveying device that facilitates the replacement of conveyor belts.

[0006] The present invention proposes a conveying device for easy replacement of conveyor belts, including a frame and a conveyor frame mounted on the frame. The conveyor frame is covered with a conveyor belt. Unlike the prior art, the conveyor frame includes a fixed side and a detachable side. The fixed side is fixed to the frame, and the detachable side is detachably mounted on the frame.

[0007] A first driven roller is installed on the disassembly side, and a first driving roller is installed on the frame. The first driving roller and the first driven roller form an outer conveyor roller of the conveyor belt.

[0008] A second driven roller is installed on the conveyor frame, and a second driving roller is installed on the frame via a lifting device. The second driving roller and the second driven roller form a conveyor roller in the conveyor belt. The lifting device is used to drive the second driving roller to move closer to or further away from the second driven roller.

[0009] Preferably, when installing or removing the conveyor belt, the lifting component drives the second driving roller to move upward and contact the second driven roller to achieve auxiliary support for the conveyor frame; or the lifting component drives the second driving roller to move upward and press against the conveyor belt, so that the second driving roller rotates and drives the conveyor belt to move.

[0010] Preferably, the height of the lowest horizontal plane tangent to the second driven roller is greater than the height of the lowest horizontal plane tangent to the first driven roller.

[0011] Preferably, at least two sets of the outer conveying rollers and the inner conveying rollers are provided, with one set of the outer conveying rollers facing the other set of the inner conveying rollers, and at least two sets of the outer conveying rollers are distributed along the conveying direction of the conveyor belt.

[0012] Preferably, a distance sensor is provided on the fixed side of the conveyor frame, and the distance sensor is used to detect the position of the conveyor belt.

[0013] Preferably, it further includes a controller, the distance sensor is connected to the controller and transmits the detected information to the controller, and the driving component that drives the first active roller to rotate and the driving component that drives the second active roller to rotate are both connected to the controller;

[0014] Once the distance sensor detects that the conveyor belt is in place, the controller stops the operation of the drive unit that drives the first active roller and the drive unit that drives the second active roller.

[0015] Preferably, the first drive roller and / or the second drive roller are electric rollers or pneumatic rollers.

[0016] Preferably, the second driven roller has a driving station and an adjusting station;

[0017] When the second driven roller is in the driving position, the axis of the second driven roller is parallel to the axis of the first driven roller, the second driving roller contacts the second driven roller to provide auxiliary support for the conveyor frame, or the conveyor belt is located between the second driving roller and the second driven roller and the second driving roller drives the conveyor belt to move.

[0018] Preferably, the length of the second driven roller is greater than the length of the second driving roller.

[0019] Preferably, a slide cylinder is rotatably mounted on the conveyor frame, a spline hole is opened at the bottom of the slide cylinder, a slider is vertically slidably mounted in the spline hole, a sealing plate is provided at the bottom of the slide cylinder to limit the displacement of the slider, a sliding rod is connected to the bottom of the slider, the sliding rod passes through the sealing plate and is connected to the second driven roller;

[0020] When the second driven roller is in the drive position, the slider moves to the top of the slide cylinder.

[0021] The conveying device proposed in this invention, which facilitates the replacement of conveyor belts, has a simple structure. By setting the outer and inner conveyor rollers, it not only facilitates the installation and disassembly of the conveyor belt, but also supports the conveyor frame during the installation or disassembly process, thereby enhancing its stability and improving work efficiency.

[0022] Furthermore, the tension of the conveyor belt can be achieved through the adjustment position of the second driven roller, thus preventing the conveyor belt from slipping during transmission.

[0023] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0034] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] like Figure 1 - Figure 6 The conveying device shown is easy to replace the conveyor belt, including a conveyor frame 1, the driving roller and the driven roller of the belt drive mechanism are both installed on the conveyor frame 1, the conveyor belt 2 is sleeved on the driving roller and the driven roller, the conveyor belt 2 can be a belt, and the conveyor frame 1 is connected to an external frame (not shown in the figure).

[0036] Specifically, the conveyor frame 1 has a fixed side 10 and a disassembly side 11 located outside the conveyor belt 2, that is, the distance between the fixed side 10 and the disassembly side 11 is greater than the width of the conveyor belt 2. The fixed side 10 and the disassembly side 11 are opposite to each other and distributed along the axial direction of the drive roller. The fixed side 10 of the conveyor frame 1 is fixed with a fixed frame by bolts or screws. The fixed frame is fixedly connected to the frame by bolts or other means.

[0037] The disassembly side 11 is detachably mounted on the frame. When it is necessary to install or remove the conveyor belt 2, the disassembly side 11 is removed from the frame.

[0038] Specifically, a first driven roller 4 is installed on the disassembly side 11, a first driving roller 3 is installed on the frame, and an outer conveyor roller group of the conveyor belt 2 is formed between the first driving roller 3 and the second driving roller 5.

[0039] A second driven roller 6 is installed in the middle of the conveyor frame 1. That is, the first driven roller 4 and the second driven roller 6 are distributed on the conveyor frame 1 along the width direction of the conveyor belt 2. A second driving roller 5 is installed on the frame through a lifting component 7. The lifting component 7 can be an electric cylinder or a pneumatic cylinder in the prior art. In this embodiment, the lifting component 7 is an electric cylinder. The distance between the second driving roller 5 and the second driven roller 6 can be adjusted. The second driving roller 5 and the second driven roller 6 form a conveying roller group in the conveyor belt 2.

[0040] When it is necessary to install the conveyor belt 2, the disassembly side 11 is disassembled from the frame. Specifically, a connecting frame is detachably installed between the frame and the disassembly side 11 (since the connection between the frame and the conveyor frame 1 via the connecting frame is existing technology, the above structure is not shown in the figure), thereby realizing the disassembly of the frame and the disassembly side 11.

[0041] During the disassembly process, the lifting mechanism moves upward, causing the second active roller 5 and the second driven roller 6 to press against the conveyor belt 2 below. Then, the second active roller 5 rotates under the action of the driving component (not shown in the figure), thereby causing the conveyor belt 2 to move away from the fixed side 10 until the conveyor belt 2 moves above the first driven roller 4. Then, the staff adjusts the conveyor belt 2 between the first active roller 3 and the second driven roller 6. The first active roller 3 and the second active roller 5 drive the conveyor belt 2 to move outward in sync until the second active roller 5 disengages from the conveyor belt 2. At this time, the second active roller 5 stops moving, and the first active roller 3 drives the conveyor belt 2 to disengage from the conveyor frame 1 and the outer conveyor roller group.

[0042] During the feeding process, the lower end of the conveyor belt 2 is positioned between the first driving roller 3 and the first driven roller 4. Then, the first driving roller 3 rotates, causing the conveyor belt 2 to move closer to the conveyor frame 1. The conveyor belt 2 is then placed on the conveyor frame 1. The first driving roller 3 continues to drive the conveyor belt to move closer to the fixed side 10. During this process, the lifting mechanism drives the second driving roller 5 to move upward, so that the second driving roller 5 contacts the second driven roller 6 to support the middle of the conveyor frame 1 and increase its overall stability. Until the conveyor belt 2 is near the second driving roller 5, the lifting component 7 adjusts the height of the second driving roller 5, and then guides the conveyor belt 2 between the second driving roller 5 and the second driven roller 6. The inner conveyor roller group and the outer conveyor roller group then convey and guide the conveyor belt 2.

[0043] Preferably, the axis of the first driven roller 4 is lower than the axis of the second driven roller 6 in the vertical direction, which facilitates the disassembly and installation of the conveyor belt 2; and during the disassembly or installation of the conveyor belt 2, the first driven roller 4 and the first driving roller 3 are connected by the conveyor belt 2, which indirectly provides auxiliary support to the conveyor frame 1.

[0044] Preferably, both the inner and outer conveyor roller groups are provided in at least two sets, with one set of inner conveyor roller groups facing the other set of outer conveyor roller groups, and at least two sets of outer conveyor roller groups distributed along the length of the conveyor belt 2. This facilitates the disassembly and installation of the conveyor belt 2. In this embodiment, both the inner and outer conveyor roller groups are provided in two sets.

[0045] Preferably, a distance sensor 8 is provided at the fixed end of the conveyor frame 1. The distance sensor 8 is used to detect the distance between the conveyor belt 2 and the fixed side 10 of the conveyor frame 1, thereby indirectly determining whether the conveyor belt 2 is in position relative to the conveyor frame 1.

[0046] Preferably, the system also includes a controller. The distance sensor 8 is connected to the controller, the lifting component 7 is connected to the controller, and the driving component that drives the first active roller 3 and the driving component that drives the second active roller 5 are both connected to the controller. The controller controls the lifting component 7 to move up and down, and the controller also controls the first active roller 3 and the second active roller to rotate. When it is necessary to disassemble or install the conveyor belt 2, the controller is manually controlled to open the first active roller 3 and the second active roller 5 and to raise and lower the lifting component 7. During the installation of the conveyor belt 2, if the distance sensor 8 detects that the conveyor belt 2 is installed in place, it transmits the information to the controller, and the controller controls the first active roller 3 and the second active roller 5 to stop moving.

[0047] When the conveyor belt 2 is not in the process of installation or disassembly, the lifting component 7 is at its lowest position, and the second driving roller 5 is lower than the bottom of the conveyor belt 2. When the conveyor belt 2 is in the process of installation or disassembly, the lifting component 7 drives the second driving roller 5 to move upward and contact the conveyor belt 2 or the second driven roller 6, so as to drive the conveyor belt 2 or provide auxiliary support for the conveyor frame 1.

[0048] Specifically, the first driving roller 3 and the second rotating roller can be electric rollers or pneumatic rollers.

[0049] Example 2

[0050] like Figures 7-9 As shown, the difference between this embodiment and the above embodiments is that the second driven roller 6 has a driving station and an adjusting station;

[0051] When the second driven roller 6 is in the driving position, the axis of the second driven roller 6 is parallel to the axis of the first driven roller 4, and the lowest side of the second driven roller 6 is in the same horizontal plane as the lowest side of the pulley of the conveyor belt 2.

[0052] When the second driven roller 6 is in the adjustment position, its axis is along the width of the conveyor belt 2, and it is positioned above and in contact with the bottommost conveyor belt 2, thus preventing the conveyor belt from being slack. When the second driven roller 6 is in the adjustment position, its vertical position can be adjusted to ensure that it is in contact with the bottommost layer of the conveyor belt 2.

[0053] Specifically, the second driven roller 6 is rotatably mounted on the bracket 9. When the second driven roller 6 is in the adjustment position, the bracket 9 can adjust the vertical position of the second driven roller 6 via the sliding rod 13. The second driven roller 6 is vertically slidably mounted in the slide cylinder 14 via the sliding rod 13, and the slide cylinder 14 is vertically rotatably mounted on the conveyor frame 1. The slide cylinder 14 can be driven to rotate by an existing motor (not shown in the figure), thereby adjusting the second driven roller 6 to be in the adjustment position or the drive position.

[0054] Specifically, a spline hole is opened inside the slide cylinder 14, and a sliding block matching the spline hole is vertically slidably installed inside the spline hole. A sealing plate 15 is installed on the slide cylinder 14, and a through hole is opened on the sealing plate 15. The diameter of the through hole is smaller than the diameter of the spline hole. The sliding rod 13 passes through the through hole and is connected to the sliding block, thereby limiting the vertical displacement of the sliding block, which in turn limits the vertical movement of the second driven roller 6.

[0055] When the second driven roller 6 is in the driving position, the second driving roller 5 is in linear contact with the second driven roller 6, and the lifting component 7 drives the second driven roller 6 to move to the top, that is, drives the sliding block to move to the top, thereby limiting the second driven roller 6 in the vertical direction. Then the second driving roller 5 rotates to convey the conveyor belt 2, or the second driving roller 5 contacts the second driven roller 6 and supports the conveyor frame 1.

[0056] When the second driven roller 6 is in the adjustment position, the axis of the second driven roller 6 is along the length of the conveyor belt 2 and the second driven roller 6 is located above the conveyor belt 2. The conveyor belt 2 supports the lower part of the second driven roller 6. If the conveyor belt 2 is loose, the second driven roller 6 and the support 9 will move downward through the slider 12 under the gravity of the second driven roller 6 and the support 9, thereby adjusting the tension of the conveyor belt 2.

[0057] It should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0058] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0059] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.
