Description

Technical Field

[0001] This application relates to the field of conveyor belt technology, specifically a foldable and portable conveyor belt device. Background Technology

[0002] With the rapid development of logistics, warehousing, and transportation industries, portable conveyor belt equipment has been widely used in cargo handling and goods transportation.

[0003] Traditional portable conveyor belts typically have low tension to achieve folding and storage functionality, allowing for a certain degree of slack. However, once the equipment is unfolded, this slack can easily lead to unstable material transport, or even material slippage or jamming, thus affecting work efficiency. In addition, to accommodate folding and storage, conveyor belts are usually made of highly elastic materials. While this design gives the equipment good foldability, the conveyor belt may be subjected to significant stretching and pressure during frequent folding and unfolding, leading to material fatigue. This results in insufficient tension after prolonged use, affecting transmission.

[0004] Therefore, this application provides a foldable and portable conveyor belt device to solve the above problems. Utility Model Content

[0005] This application provides a foldable and portable conveyor belt device, which aims to solve the problems mentioned in the background art, such as the unstable material transportation and easy slippage and jamming caused by the low tension relaxation state of the existing portable conveyor belts designed for folding and storage, which affects efficiency, and the use of elastic materials which, although convenient for folding, can cause material fatigue and insufficient tension due to frequent operation, thus affecting the transmission.

[0006] To achieve the above objectives, this application provides the following technical solution: a foldable and portable conveyor belt device, comprising a first frame, a second frame disposed on one side of the first frame and hinged to the first frame, an active roller and a driven roller respectively rotatably connected to one end of the first frame and the second frame away from each other, a conveyor belt disposed on the active roller and the driven roller, and a motor fixedly disposed on the first frame for driving the active roller to rotate, wherein the active roller and the driven roller are connected and transmit power through the conveyor belt;

[0007] The portable conveyor belt device also includes a tension roller disposed on the second frame and located inside the conveyor belt for tensioning the conveyor belt, and a lifting assembly disposed on the second frame for pressing the tension roller against the bottom inner side of the conveyor belt. Through the combined design of the lifting assembly and the tension roller, when the conveyor belt device needs to be folded, the tension roller can be driven upward by the lifting assembly to release the pressure on the conveyor belt, thereby reducing the tension of the conveyor belt and making it easier to fold, facilitating the storage and carrying of the device. Conversely, when the conveyor belt is unfolded, the tension roller can be pressed down to tension the conveyor belt, ensuring that the conveyor belt maintains good tension and working condition. This also reduces the problem of the conveyor belt loosening due to repeated folding over a long period, which affects the performance and improves the durability of the device.

[0008] Preferably, in order to achieve the conveyor belt conveying effect, support rollers are rotatably connected to both the first frame and the second frame in a linear distribution to support the inner top of the conveyor belt; the linear distribution design of the support rollers can form continuous support for the inner top of the conveyor belt when conveying materials on the surface of the conveyor belt, avoiding sagging, twisting or deviation of the conveyor belt due to idling or uneven load, and ensuring stable material transmission.

[0009] Preferably, in order to achieve the lifting and lowering of the tension roller, the lifting assembly includes two grooves opened on the second frame corresponding to the two ends of the tension roller, a slider slidably connected in the grooves, and a servo electric cylinder fixedly installed in the grooves for driving the slider to lift and lower. The two ends of the tension roller are respectively rotatably connected to the two sliders. By driving the slider to lift and lower in the grooves by the servo electric cylinder, the tension roller can be automatically lifted and lowered without the need for manual pushing or pulling of the tension roller, making the operation simple and convenient.

[0010] Preferably, in order to facilitate locking the unfolded second frame and the first frame, a pin is slidably connected to the outer side of the slide corresponding to the groove on the second frame, and a slot for the pin to be inserted is fixedly installed on the first frame. The combination design of the pin and the slot allows the first frame and the second frame to be locked together by inserting the pin into the slot after the device is unfolded, ensuring the stability of the device during transmission. Conversely, the locking of the first frame and the second frame can be released by pulling the pin out of the slot.

[0011] Preferably, to facilitate the insertion and disengagement of the pin and slot, the portable conveyor belt device further includes a transmission component disposed on the second frame at the position corresponding to the slide groove and connected to the slider and the pin, for transmitting power from the slider to the pin, causing the pin to move into or out of the slot; the transmission component synchronously transmits power from the slider to the pin, so that before the tension roller rises and the conveyor belt folds, the pin can be synchronously disengaged from the slot, releasing the lock of the first and second frames; conversely, when the tension roller is lowered by the slider to tighten the conveyor belt, the pin can be synchronously inserted into the slot, locking the first and second frames. This simplifies the operation process, eliminates the need for manual locking or unlocking operations, and improves work efficiency.

[0012] Preferably, in order to realize the insertion or disengagement of the pin into the slot, the transmission assembly includes a toothed plate slidably connected in the slide groove and fixedly connected to the slider, a fixed frame fixedly disposed on the second frame corresponding to the outside of the slide groove, a gear disposed in the fixed frame and meshing with the toothed plate, and a lead screw passing through the fixed frame and fixedly connected to the gear. The lead screw is screwed to the pin and rotatably connected to the fixed frame. Through the meshing of the toothed plate and the gear, the linear motion of the slider can be converted into the rotational motion of the gear. When the gear rotates, it can quickly transmit power to the lead screw, thereby driving the pin to move and realizing the insertion or disengagement of the pin.

[0013] Preferably, to ensure the use of the pin, a limiting block is fixedly connected to one side of the pin, and the second frame has a limiting groove on the side of the pin for the limiting block to slide. The combined design of the limiting block and the limiting groove provides a clear movement path for the pin, ensuring the stability and accuracy of the pin during movement, preventing the pin from shifting or disengaging from the lead screw during insertion or disengagement, and ensuring the reliability of the device during locking and unlocking.

[0014] This foldable and portable conveyor belt device uses a combination design of lifting components and tension rollers. When the conveyor belt device is folded, the lifting components drive the tension rollers to rise and release the pressure on the conveyor belt, reducing tension to facilitate folding, storage and carrying. When the conveyor belt is unfolded, the tension rollers press down to tighten the conveyor belt, ensuring its good tension and working condition. At the same time, it reduces the problem of conveyor belt loosening caused by repeated folding over a long period of time, and improves the durability of the device.

[0015] This foldable and portable conveyor belt device uses a combination of pins and slots. When the device is unfolded, the first and second frames can be locked together by inserting the pins into the slots, ensuring the stability of the device during transmission. Conversely, the locking of the first and second frames can be released by pulling the pins out of the slots.

[0016] This foldable and portable conveyor belt device uses a transmission component to synchronously transmit power from the slider to the pin. Before the tension roller rises to fold the conveyor belt, it can simultaneously drive the pin to disengage from the slot, releasing the lock of the first and second frames. When the slider drives the tension roller to descend and press the conveyor belt, it can simultaneously drive the pin to insert into the slot to complete the locking. This simplifies the operation process, eliminates the need for manual locking or unlocking, and effectively improves work efficiency. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Example 1

[0033] This embodiment provides a foldable and portable conveyor belt device, such as... Figures 1-4 As shown, the portable conveyor belt device includes a first frame 1, a second frame 2 disposed on one side of the first frame 1 and hinged to the first frame 1, a drive roller 11 and a driven roller 21 respectively rotatably connected to one end of the first frame 1 and the second frame 2 away from each other, a conveyor belt 3 disposed on the drive roller 11 and the driven roller 21, and a motor fixedly disposed on the first frame 1 for driving the drive roller 11 to rotate. The drive roller 11 and the driven roller 21 are connected and transmit power through the conveyor belt 3. The portable conveyor belt device also includes a tension roller 4 disposed on the second frame 2 and located inside the conveyor belt 3 for tensioning the conveyor belt 3, and a lifting assembly 5 disposed on the second frame 2 for pressing the tension roller 4 against the bottom inner side of the conveyor belt 3.

[0034] In order to achieve the conveying effect of the conveyor belt 3, support rollers 6 are rotatably connected to the first frame 1 and the second frame 2 in a linear distribution to support the inner top of the conveyor belt 3. The linear distribution of the support rollers 6 can form continuous support for the inner top of the conveyor belt 3 when the material is conveyed on the surface of the conveyor belt 3, so as to avoid the conveyor belt 3 from sagging, twisting or running off-center due to idling or uneven load, and ensure the smooth transmission of materials.

[0035] In use, when folding is required, the operator activates the lifting assembly 5, driving the tension roller 4 upward. As the tension roller 4 gradually rises and moves away from the inner bottom of the conveyor belt 3, the pressure on the inner bottom of the conveyor belt 3 is released, thereby reducing the tension of the conveyor belt 3 and placing it in a relaxed state. Because the tension of the relaxed conveyor belt 3 is reduced, the resistance during folding is low and wrinkles or wear are less likely to occur, facilitating folding. Then, the operator manually pulls the first frame 1 or the second frame 2, causing the first frame 1 or the second frame 2 to rotate and fold around the hinge point of the first frame 1 and the second frame 2 towards the second frame 2 or the first frame 1. During this process, the driving roller 11 and the driven roller 21 move closer together as the first frame 1 and the second frame 2 approach, causing the conveyor belt 3 to fold accordingly. When unfolding is required, [the following steps are taken]. The first frame 1 or the second frame 2 rotates and unfolds around the hinge point, gradually moving the first frame 1 and the second frame 2 away until they are in a straight line. Then, the lifting assembly 5 is activated to drive the tension roller 4 downward in the opposite direction, causing the tension roller 4 to move downward and press against the inner bottom end of the conveyor belt 3. This creates appropriate tension between the drive roller 11 and the driven roller 21 on the conveyor belt 3, ensuring that the conveyor belt 3 can transport items smoothly and effectively. Then, the motor is started to drive the drive roller 11 to rotate. Since the drive roller 11 and the driven roller 21 are connected and transmit power through the conveyor belt 3, the driven roller 21 will also rotate, thereby driving the conveyor belt 3 to circulate. The operator places the items to be transported at one end of the conveyor belt 3. As the conveyor belt 3 circulates, the items will be transported to the other end, thus completing the transport task.

[0036] Specifically, the lifting assembly 5 includes two grooves 51 opened on the second frame 2 at the positions corresponding to the two ends of the tension roller 4, a slider 52 slidably connected in the grooves 51, and a servo electric cylinder 53 fixedly installed in the grooves 51 for driving the slider 52 to rise and fall. The two ends of the tension roller 4 are respectively rotatably connected to the two sliders 52.

[0037] When it is necessary to drive the tension roller 4 to press down, the servo cylinder 53 is activated. At this time, the piston rod of the servo cylinder 53 begins to extend. As the piston rod of the servo cylinder 53 extends, the slider 52 will also slide down in the groove 51 in sync. Since the two ends of the tension roller 4 are respectively rotatably connected to the two sliders 52, as the sliders 52 slide down, the tension roller 4 will also descend until it is pressed against the bottom of the inner side of the conveyor belt 3. When it is necessary to drive the tension roller 4 to rise, the piston rod of the servo cylinder 53 can be activated to retract. As the piston rod of the servo cylinder 53 retracts, the slider 52 will rise in the groove 51. Thus, the rise of the slider 52 will synchronously drive the tension roller 4 to rise, thereby releasing the pressure on the conveyor belt 3.

[0038] It should be noted that the portable conveyor belt device is also equipped with a button for extending or retracting the piston rod of the servo cylinder 53, so that the operator can start and stop the servo cylinder 53.

[0039] Furthermore, a pin 22 is slidably connected to the outer side of the slide groove 51 on the second frame 2, and a slot 12 for the pin 22 to be inserted is fixedly installed on the first frame 1.

[0040] The operator unfolds the hinged first frame 1 and second frame 2, placing them on the same plane. After the conveyor belt 3 is pressed down by the lifting assembly 5, the movable pin 22 is gradually moved closer to the slot 12 on the first frame 1 and inserted into the slot 12. At this point, the first frame 1 and second frame 2 are locked together by the insertion of the pin 22 and the slot 12, ensuring stability and reliability during equipment operation. Conversely, when the equipment needs to be folded for storage, the tension roller 4 is first raised by the lifting assembly 5 to release the pressure on the conveyor belt 3. Then, the pin 22 is moved to disengage it from the slot 12, releasing the insertion of the pin 22 and the slot 12. This releases the locking state between the first frame 1 and second frame 2, restoring their relative freedom of movement. The first frame 1 and second frame 2 can then be folded.

[0041] Example 2

[0042] Unlike Example 1, as Figures 5-6 To facilitate the insertion and disengagement of the pin 22 and the slot 12, the portable conveyor belt device also includes a transmission component 7 located on the second frame 2 at the position corresponding to the slide groove 51 and connected to the slider 52 and the pin 22. This component transmits power from the slider 52 to the pin 22, causing the pin 22 to move and insert or disengage from the slot 12. The transmission component 7 synchronously transmits power from the slider 52 to the pin 22, so that before the tension roller 4 rises and the conveyor belt 3 is folded, the pin 22 can be synchronously disengaged from the slot 12, releasing the lock between the first frame 1 and the second frame 2. Conversely, when the tension roller 4 is lowered by the slider 52 to press the conveyor belt 3, the pin 22 can be synchronously inserted into the slot 12, locking the first frame 1 and the second frame 2. This simplifies the operation process, eliminates the need for manual locking or unlocking operations, and improves work efficiency.

[0043] Furthermore, the transmission assembly 7 includes a toothed plate 71 that is slidably connected in the slide groove 51 and fixedly connected to the slider 52, a fixed frame 72 that is fixedly set on the outside of the slide groove 51 of the second frame 2, a gear 73 that is set in the fixed frame 72 and meshes with the toothed plate 71, and a lead screw 74 that passes through the fixed frame 72 and is fixedly connected to the gear 73. The lead screw 74 is screwed to the pin 22 and is rotatably connected to the fixed frame 72.

[0044] When the equipment needs to be unfolded for use, the servo cylinder 53 in the lifting assembly 5 drives the slider 52 to move downward in the slide groove 51, and drives the conveyor belt 3 to press down. Because the toothed plate 71 and the gear 73 mesh with each other, the downward movement of the toothed plate 71 drives the gear 73 to rotate in the fixed frame 72. The gear 73 is fixedly connected to the lead screw 74. When the gear 73 rotates, it will drive the lead screw 74 to rotate together on the fixed frame 72. Since the lead screw 74 is screwed to the pin 22, when the lead screw 74 rotates, the pin 22 will move along the axial direction of the lead screw 74 to one side of the slot 12 until it is inserted into the slot 12 on the first frame 1. At this time, the tension roller 4 presses the conveyor belt 3 simultaneously. Then, the first frame 1 and the second frame 2 can be locked by the insertion of the pin 22 into the slot 12, ensuring that the equipment is in the unfolded state for use. The structural stability provides reliable support for the normal operation of the conveyor belt 3. Conversely, when the equipment needs to be folded for storage, the slider 52 is driven by the servo cylinder 53 to move upward in the slide groove 51 and drive the tension roller 4 to rise. The slider 52 will drive the toothed plate 71 to rise synchronously. As the toothed plate 71 rises, through the meshing of the toothed plate 71 and the gear 73, the gear 73 and the lead screw 74 will rotate in opposite directions on the fixed frame 72. As the lead screw 74 rotates in the opposite direction, the pin 22 will move away from the slot 12 along the axial direction of the lead screw 74 until it is completely pulled out of the slot 12 on the first frame 1. At this time, the locking state between the first frame 1 and the second frame 2 is released, and the tension roller 4 also rises to release the pressure on the conveyor belt 3. The user can fold the first frame 1 and the second frame 2 relative to each other to realize the storage of the equipment.

[0045] In addition, to ensure the use of the pin 22, a limiting block 23 is fixedly connected to one side of the pin 22, and a limiting groove 24 is provided on the side of the second frame 2 corresponding to the pin 22 for the limiting block 23 to slide. The combined design of the limiting block 23 and the limiting groove 24 provides a clear movement path for the pin 22. When the pin 22 is moving, the limiting block 23 will move synchronously in the limiting groove 24 to ensure the stability and accuracy of the pin 22 during the movement process, prevent the pin 22 from deviating or disengaging from the lead screw 74 during the insertion or disengagement process, and ensure the reliability of the equipment during the locking and unlocking process.

[0046] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
