Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and more specifically, to a mobile belt discharge mechanism. Background Technology

[0002] Belt conveyors are common continuous conveying equipment on automated production lines. However, existing belt conveyors are typically fixed installations, and the position of the belt body cannot be flexibly adjusted. In space-constrained or densely packed environments, the discharge port of a fixed belt conveyor often interferes with the movement trajectories of other surrounding equipment, such as robotic arms, lifting platforms, or other conveying devices. This interference can lead to equipment malfunction or require increased spacing between equipment to allow for safety, thus reducing space utilization. To address the interference problem, existing technologies sometimes employ swingable or liftable belt conveyors, but these structures are often complex, costly, or have limited adjustment ranges.

Detailed Implementation

[0015] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this disclosure. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0016] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model 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, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Please refer to Figures 1 to 6 This utility model provides a mobile belt discharge mechanism, including a frame 1, a belt mechanism 2, a moving mechanism 3, and a connecting arm 4; the belt mechanism 2 is slidably connected to the frame 1, and the moving mechanism 3 is fixedly installed inside the frame 1; the moving mechanism 3 includes a cylinder 31, one end of the connecting arm 4 is connected to the belt mechanism 2, and the other end is connected to the piston rod of the cylinder 31.

[0019] In this embodiment of the invention, the entire structure consists of a frame 1, a belt mechanism 2, a moving mechanism 3, and a connecting arm 4. The moving mechanism 3 is fixed inside the frame 1, optimizing space utilization and facilitating installation and deployment in confined working environments. This simple structural design reduces the difficulty of component processing and assembly, making manufacturing costs more advantageous and facilitating subsequent maintenance.

[0020] Specifically, frame 1 is used to support various components and also to connect equipment on the production line. For example, on a packaging production line, frame 1 is connected to the packaging machine to realize the back-and-forth movement and conveying of materials. The belt mechanism 2 can achieve a sliding connection with frame 1 through sliding devices, such as slide bars or slide rail moving mechanisms 3. The moving mechanism 3 uses cylinder 31 as a power source, and works with connecting arm 4 to achieve direct power transmission, forming a simple and efficient transmission link. The cylinder 31 drive has the characteristics of fast response speed and stable power output, which can quickly drive the belt mechanism 2 to complete position switching, adapting to the high-frequency material receiving and discharging operation requirements; the setting of connecting arm 4 can avoid the conveying path of the belt, making the installation position of cylinder 31 more flexible.

[0021] During operation, cylinder 31 precisely transmits power to belt mechanism 2 via connecting arm 4, driving it to move stably to the right along frame 1 to the preset receiving position, ensuring accurate material reception. After material reception, cylinder 31 reverses direction, driving belt mechanism 2 to move to the left, quickly moving it away from areas prone to interference with other mechanisms. Compared to traditional fixed-installation belt discharge mechanisms, this embodiment solves the interference problem in multi-mechanism collaborative operation, eliminating the need to stop the machine to adjust the positions of other mechanisms, ensuring the continuity and smoothness of the production process, and improving overall operating efficiency.

[0022] This embodiment is highly versatile and can be adapted and adjusted according to the material transfer requirements of different production lines, making it easy to promote and apply in various material transfer scenarios.

[0023] Preferably, the belt mechanism 2 includes a belt frame 21, a telescopic belt 22, a drive roller 23, and a plurality of driven rollers 24; the telescopic belt 22 is wound around the drive roller 23 and the driven rollers 24; one end of the drive roller 23 is provided with a sprocket 25, which is used to connect an external drive motor; the drive roller 23 and the driven rollers 24 are rotatably mounted on the belt frame 21; guide rails 26 are symmetrically arranged on both sides of the belt frame 21, and sliders 27 that can slide along their length are provided on the guide rails 26. A pad 28 is provided on the slider 27, and the slider 27 and the pad 28 are connected to the frame 1.

[0024] In this embodiment, the guide rails 26 symmetrically arranged on both sides of the belt frame 21 are slidably connected to the slider 27, providing precise guidance for the movement of the belt mechanism 2. Combined with the cylinder 31 drive and connection structure, the belt mechanism 2 can be flexibly adjusted to move to the appropriate position when receiving material and return to its original position after receiving material, effectively solving the problem of interference with other equipment in traditional fixed belt mechanisms 2. It eliminates the need to interrupt the production process to adjust equipment positions, ensuring smooth collaborative operation of multiple mechanisms. The driving roller 23 and driven roller 24 are mounted on the belt frame 21, and the telescopic belt 22 winds around the driving roller 23 and driven roller 24. The driving roller 23 is equipped with a sprocket 25, which can be connected to a drive motor via a chain. The drive motor drives the driving roller 23 to rotate. The driving roller 23 drives the telescopic belt 22 wound around it through friction, simultaneously driving several driven rollers 24 to rotate synchronously, forming a belt transmission link, and thus driving the orderly transmission of material on the telescopic belt 22.

[0025] Preferably, the guide rail 26 is a linear guide rail 26, and the slider 27 is a roller slider 27. In this embodiment, the linear guide rail 26 has high-precision guiding characteristics, and combined with the low rolling resistance of the roller slider 27, the belt mechanism 2 can move along the guide rail 26 without jamming or offset, and the movement response speed and position accuracy are better than those of ordinary sliding rails.

[0026] Preferably, the linear guide rail 26 is provided with a pair of limiting blocks, which are used to limit the extreme positions of the slider 27's left and right movements. In this embodiment, the pair of limiting blocks are respectively located at the left and right ends of the linear guide rail 26, and respectively physically block the extreme positions of the slider 27's left and right movements, avoiding the belt mechanism 2 from moving beyond its travel range due to excessive drive of the cylinder 31 or control errors, preventing the inability to receive materials, and also avoiding interference with other mechanisms, so that the position adjustment of the belt mechanism 2 is always within a safe and effective range.

[0027] Preferably, there are three driven rollers 24, namely driven roller one, driven roller two, and driven roller three; the belt frame 21 is provided with adjusting grooves 21a on both sides, and adjusting holes 21b are provided on the adjusting grooves 21a and adjusting bolts are provided on the adjusting holes 21b; both ends of driven roller one are provided with threaded holes 25a that match the adjusting screws, and the adjusting bolts on both sides of the belt frame are threadedly connected to the threaded holes 25a at both ends of driven roller one. In this embodiment, driven roller one, driven roller two, and driven roller three are set to form a multi-point support structure, wherein driven roller one undertakes the tensioning function, and driven rollers two and three undertake the auxiliary support function. With the above structural setting, the contact area of ​​the telescopic belt 22 is larger, the jumping amplitude during operation is significantly reduced, and slippage and shaking phenomena are reduced. When it is necessary to tension the telescopic belt 22, the operator can directly drive driven roller one to move linearly along the adjusting groove 21a by rotating the adjusting bolts on both sides to achieve fine adjustment of the belt tension. The limiting function of the adjusting groove 21a ensures that the moving direction of the driven roller 1 is parallel to the running direction of the belt, avoiding the belt from running off track due to the deviation of the driven roller 24 during the adjustment process. After adjustment, there is no need to correct the position of the driven roller 24. The thread engagement between the adjusting bolt and the threaded hole 25a has self-locking properties. After adjustment, the position of the driven roller 24 1 is stable and will not loosen due to belt running vibration. The tension state is durable and reliable.

[0028] Preferably, the connecting arm 4 includes a first arm 41, a second arm 42, and a third arm 43. The first arm 41 and the second arm 42 are arranged perpendicularly to each other, and the first arm 41 is connected to the belt frame 21. The third arm 43 is arranged perpendicularly to the second arm 42, and the piston rod of the cylinder 31 is connected to the third arm 43. In this embodiment, the first arm 41 is perpendicular to the second arm 42, and the second arm 42 is perpendicular to the third arm 43. This allows for symmetrical arrangement of guide rails 26 on both sides of the power transmission direction within a limited equipment space. This adapts to installation scenarios where the cylinder 31 and the belt frame 21 are not on the same plane, avoiding spatial interference caused by the cylinder 31 directly connecting to the belt frame 21, and making the installation position of the cylinder 31 more flexible.

[0029] Furthermore, the first arm 41, the second arm 42, and the third arm 43 are integrally formed structures, and reinforcing ribs are provided at the connection between the first arm 41 and the second arm 42, and at the connection between the second arm 42 and the third arm 43, to further enhance the structural strength of the connecting arm 4.

[0030] Preferably, the first support arm 41 is provided with a sliding groove 41a, and the belt frame 21 is provided with a plurality of mounting holes 21c that mate with the sliding groove 41a. The plurality of mounting holes 21c are arranged along the length direction of the sliding groove 41a. With the above structural arrangement, the sliding groove 41a provides guidance for the relative movement of the first support arm 41 and the belt frame 21. With the cooperation of the plurality of mounting holes 21c distributed along the length direction of the sliding groove 41a, the position of the connecting arm 4 relative to the belt frame 21 can be finely adjusted. There is no need to re-drill holes or process the positioning surface. It can adapt to the relative position deviation between the cylinder 31 and the belt frame 21. This means that the connecting arm 4 does not need to be repeatedly calibrated during installation. It can be fixed simply by sliding along the sliding groove 41a to the position of the target mounting hole 21c. This greatly reduces the alignment difficulty during assembly and shortens the assembly time.

[0031] Preferably, the frame 1 includes two opposing supports, each support comprising a top plate 11, a side plate 12, and a bottom plate 13. The top plate 11 has a downwardly bent guide slope 14 at one end near the belt conveyor 2. The side plates 12 are connected to both the belt conveyor 2 and the moving mechanism 3. The bottom plate 13 has several connecting holes 15. In this embodiment, the two supports are arranged opposite to each other, together enclosing the belt conveyor 2 and the moving mechanism 3, providing protection. Simultaneously, the downwardly bent guide slope 14 at the end of the top plate 11 guides the material, preventing it from getting stuck at the edge of the top plate 11 during transport.

[0032] Preferably, the moving mechanism 3 further includes a crossbeam 32, with both ends of the crossbeam 32 connected to the frame 1, and the cylinder body of the cylinder 31 connected to the crossbeam 32. In this embodiment, the crossbeam 32 connects to the frame 1 at both ends to form a lateral support, which not only enhances the overall rigidity of the frame 1 and avoids deformation under unilateral force, but also provides a stable and uniform mounting reference for the cylinder body of the cylinder 31, reducing drive deviation. The cylinder 31 is directly fixed to the crossbeam 32 without the need for additional supports, making the internal structure of the entire mechanism more compact.

[0033] Preferably, a displacement sensor is provided inside the frame 1, and a sensing block is provided on the side of the belt mechanism 2; the detection end of the displacement sensor is correspondingly arranged with the sensing block and is used to monitor the displacement change of the sensing block. In this embodiment, the structure of providing a displacement sensor inside the frame 1 and a sensing block on the side of the belt mechanism 2 enables real-time monitoring and control of the displacement of the belt mechanism 2. The detection end of the displacement sensor faces the sensing block, which can dynamically capture the positional changes of the belt mechanism 2 and promptly identify whether the movement of the belt mechanism 2 is normal, avoiding failure to receive materials due to incomplete movement.

[0034] Furthermore, the displacement sensor can be a grating displacement sensor or a laser displacement sensor.

[0035] Compared with existing technologies, the advantages of this invention are as follows: By setting the belt mechanism to a structure that can slide relative to the frame and using a cylinder and connecting arm to drive the belt mechanism, the reciprocating movement adjustment of the belt mechanism is realized. When materials need to be transferred, the entire belt mechanism moves to a suitable position, and after receiving the materials, it moves in the opposite direction to avoid the interference area. This effectively solves the problem of interference between existing fixed-installation belt discharge mechanisms and other mechanisms, ensuring the smooth operation of multiple mechanisms in coordination. In addition, two symmetrically arranged guide rails and sliders provide stable guidance for the movement of the belt frame, ensuring that the telescopic belt will not deviate during movement and guaranteeing the stability of material transfer. The overall structure of this invention is simple, it uses cylinder drive, has reliable transmission and rapid response, and has low manufacturing cost. It is easy to install and maintain, making it suitable for widespread application in various material transfer production lines.
