Description

Technical Field

[0001] This utility model relates to conveyor belts, and more particularly to a dedicated connecting mechanism for conveyor belts. Background Technology

[0002] Currently, Chinese utility model patent CN223534283U discloses a conveyor belt that can effectively prevent material from falling. The device mainly consists of a frame, supporting rollers, a conveyor belt body, and a scraper and pusher assembly located at the bottom. Its core design utilizes the scraper to scrape off any material adhering to the return conveyor belt to the bottom of the frame, and a servo motor drives the pusher to push the accumulated material to one side for centralized collection. While this structure effectively solves the problem of ground pollution and resource waste caused by powder or granular materials falling during the return journey, its support structure at the end of the conveyor belt is relatively simple.

[0003] However, significant technical drawbacks exist when applying this conveyor belt to the conveying and cutting of slender materials such as wire harnesses. To smoothly transport the wire harness to the cutter and ensure a straight cut, a connecting plate is typically installed between the conveyor belt output end and the cutter, and the upper surface of the connecting plate must be as flush as possible with the upper surface of the conveyor belt. Since the conveyor belt in the aforementioned patent runs over a cylindrical support roller, the geometric curvature of the outer circumference of the support roller inevitably creates a wedge-shaped gap between the conveyor belt at its downward turning point and the flat connecting plate. When conveying wire harnesses composed of multiple strands of fine filaments, the delicate threads easily become embedded or entangled in this gap, causing material entanglement and accumulation, which can lead to conveyor belt jamming or even equipment shutdown. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a special connecting mechanism for conveyor belts to avoid jamming of the conveyor belt body.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a special connecting mechanism for conveyor belts, including a conveyor belt body, a connecting plate, and a support base. The conveyor belt body is rotatably connected to the support base, the connecting plate is located at the end of the conveyor belt body, the connecting plate is hinged to the support base, the connecting plate has a contact surface, and the support base is provided with an elastic structure that drives the connecting plate to move closer to the conveyor belt body. When the contact surface is in close contact with the bend of the conveyor belt body, the upper surface of the connecting plate is flush with the upper surface of the conveyor belt body.

[0006] To achieve the above technical solution, during operation, the elastic structure mounted on the support continuously releases elastic potential energy, applying a biasing force to the connecting plate hinged to the support. This drives the connecting plate to rotate around the hinge axis, forcing the contact surface at the end of the connecting plate to actively move towards the bend of the conveyor belt body and maintain a tight fit. Utilizing the principle of elastic compensation, the geometric gap between the arc-shaped end of the conveyor belt and the connecting plate can be dynamically eliminated. Even if the conveyor belt experiences slight vibration or wear during operation, the connecting plate can adjust accordingly. Simultaneously, this tight-fitting limiting state ensures that the upper surface of the connecting plate remains flush with the upper surface of the conveyor belt body, achieving a seamless transition of the material transfer plane and effectively solving the problem of fine and soft materials such as wire harnesses easily getting stuck in gaps.

[0007] As a preferred embodiment of this utility model, the elastic structure includes an elastic element, a connecting rod, and a contact element. A connecting hole is provided on the connecting plate, the connecting rod passes through the connecting hole, the contact element is connected to the connecting rod and is used to abut against the connecting plate, and the two ends of the elastic element are respectively connected to the connecting rod and the support seat.

[0008] To achieve the above technical solution, the elastic structure establishes a transmission path through a connecting rod passing through a connecting hole in the connecting plate. The force generated by the elastic element acts on the connecting rod, which, using a contact piece fixed thereon, abuts against the surface of the connecting plate, thereby converting the linear tension or thrust of the elastic element into a torque that drives the connecting plate to rotate. The fit between the connecting hole and the connecting rod provides the necessary assembly freedom for the mechanism, ensuring that the elastic force can be reliably and directly transmitted to the connecting plate, thus guaranteeing the sensitivity of the mechanism's movements.

[0009] In a preferred embodiment of this utility model, the connecting rod is connected to the elastic element via a crossbar, and at least two connecting rods are provided, each close to the edge of the connecting plate. The connecting rod is connected to the crossbar, and the elastic element is connected to the crossbar.

[0010] To achieve the above technical solution, the elastic element acts on the crossbar, causing the crossbar to move as a whole, which in turn simultaneously pulls at least two connecting rods connected to the crossbar. Since these two connecting rods are respectively arranged on both sides near the width of the connecting plate, the traction force applied to the connecting plate by the elastic structure is more evenly distributed. This effectively prevents the connecting plate from lateral tilting or torsional deformation due to single-point force, ensuring that the contact surface on the connecting plate is evenly and straightly pressed against the bends of the conveyor belt body throughout the entire width direction, avoiding the phenomenon of one side being tight and the other loose, thus ensuring the stability of wide-width material conveying.

[0011] As a preferred embodiment of this utility model, the support base is provided with an adjustment structure for adjusting the deformation of the elastic element.

[0012] To achieve the above technical solution, the initial deformation of the elastic element can be changed by operating the adjustment structure on the support base. This gives the mechanism adjustability to the magnitude of the clamping force. Operators can make adjustments based on the material characteristics of the conveyor harness or to compensate for fatigue attenuation of the elastic element after long-term use. While ensuring a gapless fit, this optimizes the contact pressure between the contact surface and the conveyor belt, reducing unnecessary friction and wear.

[0013] In a preferred embodiment of this utility model, the adjustment structure includes a fixing member and an adjustment member. The fixing member is fixed on the support base, and the adjustment member passes through the fixing member and is threadedly connected to an adjustment sleeve. The adjustment sleeve abuts against the fixing member, and the end of the elastic member away from the connecting rod is connected to the adjustment member.

[0014] To achieve the above technical solution, during adjustment, the adjusting sleeve, which is threadedly connected to the adjusting component, is rotated to press against the fixed component and generate axial displacement, thereby driving one end of the elastic component connected to the adjusting component to move synchronously. Utilizing the self-locking and high-precision displacement characteristics of the threaded drive, stepless fine-tuning of the elastic component's deformation is achieved. This allows technicians to precisely set the clamping force of the connecting plate on the conveyor belt, and the adjusted state is stable and reliable, not easily loosened by equipment vibration.

[0015] In a preferred embodiment of this utility model, the support base is provided with a placement groove, and an installation block is detachably connected in the placement groove. A pin is passed through the installation block and inserted into the support base. The connecting plate is hinged to the support base through the pin.

[0016] To achieve the above technical solution, the mounting block is fixed within the placement groove of the support base, and the pin passes through the mounting block as the rotation fulcrum of the connecting plate. This not only realizes the hinge function of the connecting plate but also simplifies the installation and positioning process through the placement groove structure. When maintenance or replacement of the connecting plate is required, the threaded connection of the mounting block structure provides excellent disassembly, facilitating quick installation and removal of the pin by maintenance personnel, thus reducing the difficulty and cost of equipment maintenance.

[0017] As a preferred embodiment of this utility model, the upper surface of the connecting plate is provided with a guide slope, which is located at the end of the connecting plate near the conveyor belt body.

[0018] To achieve the above technical solution, a guide slope is formed on the upper surface of the connecting plate at the end closest to the conveyor belt body. When the wire harness is transmitted from the conveyor belt to the connecting plate, if there is a very small height difference between the two, the guide slope can act as a scoop and guide, smoothly lifting the wire harness onto the plane of the connecting plate. This eliminates the risk of material obstruction by the right-angled edge of the connecting plate end face, avoids rigid collision between the wire harness end and the connecting plate, and further ensures the smoothness of the feeding process before cutting.
