Description

Technical Field

[0001] This utility model relates to the field of stone processing, and in particular to a conveying mechanism used in stone processing. Background Technology

[0002] Stone is a building and decorative material formed from natural rocks (such as granite, marble, and sandstone) through quarrying, cutting, and surface treatment. It is widely used in interior and exterior decoration, flooring, countertop making, and sculpture. Due to its high hardness, strong wear resistance, and natural textured beauty, the demand for stone in the construction and decoration industries continues to grow. In the stone processing process, the raw stone blocks typically undergo cutting, grinding, and polishing. The conveyor system, as a key piece of equipment connecting these processing stages, plays a crucial role in the efficient and stable transport of raw stone materials and semi-finished products.

[0003] The conveying mechanism must withstand high loads and debris-rich operating environments for extended periods, and its stability and durability directly impact processing efficiency and finished product quality. Traditional conveying devices often employ fixed guide rollers and rigid idler rollers, which lack sufficient correction capabilities and are prone to wear or material misalignment due to belt deviation, leading to decreased processing accuracy and increased energy consumption. In existing technologies, the guide roller assembly layout is simplistic, lacking an adaptive correction mechanism and making it difficult to dynamically adjust the belt trajectory; the rigid connection of the idler roller assembly cannot adapt to changes in the weight distribution of the stone, resulting in localized stress concentration and rapid wear, and debris accumulation exacerbates frictional failure. Furthermore, traditional conveyor belts have insufficient anti-slip design, poor material positioning stability, and cleaning mechanisms rely on manual intervention, resulting in low maintenance efficiency. For high-load conditions, existing devices lack integrated elastic buffers and dynamic chip removal structures, making it difficult to balance load-bearing capacity and operational reliability, thus hindering the development of intelligent stone processing.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Example 1

[0034] As attached Figures 1 to 8 The conveying mechanism shown includes a frame 1 with a conveyor belt 101 mounted thereon.

[0035] The correction mechanism 2 is disposed on both sides of the conveyor belt 101, including a guide wheel group 201 distributed along the conveying direction, a floating bracket 202 that links the guide wheel group 201, and an elastic reset component 203 that connects the floating bracket 202 and the frame 1. The axis of the guide wheel group 201 forms a V-shaped inclined layout with the conveying direction of the conveyor belt 101, wherein the distance between the front and rear feed ends is greater than the distance between the rear feed ends.

[0036] The wear-resistant idler group 3 is located below the conveyor belt 101 and has independent floating rollers 301 arranged alternately along the conveying direction. The floating rollers 301 are connected to the frame 1 through a linkage mechanism 302.

[0037] The frame 1 serves as the main support for the conveyor belt 101. Its surface features wavy anti-slip ridges 102, which, through a top polygonal groove 1021, increase the friction of the contact surface, effectively preventing stone slippage. The polygonal groove 1021 can be triangular or trapezoidal. Removable side baffles 103 on both sides form parallel gaps with the edge of the conveyor belt 101 via inner guide strips 1031, constituting a material limiting channel. The anti-slip ridges 102 and guide strips 1031 form a collaborative limiting mechanism, both constraining the lateral displacement of the stone to provide initial positioning for the subsequent correction mechanism 2, and allowing for adjustment of the installation spacing of the side baffles 103 to accommodate different stone widths, significantly improving equipment adaptability.

[0038] The correction mechanism 2 consists of a guide wheel assembly 201, a floating support 202, an elastic reset component 203, and a bidirectional adjustment device 204. The guide wheel assembly 201 is fixed to the floating support 202 with an inclined layout that expands forward and contracts backward along its axis, forming a progressive guide surface. The floating support 202 is flexibly connected to the frame 1 through the elastic reset component 203, which includes a swing arm 2032 and a tension spring 2031. One end of the swing arm 2032 is hinged to the frame 1, and the other end is linked to the floating support 202 through the tension spring 2031 to form a linkage structure.

[0039] The bidirectional adjustment device 204 includes a screw drive assembly 2041, adjusting blocks 2042, guide grooves 2043, and limiting sliders 2044. The screw drive assembly 2041 drives the adjusting blocks 2042 on both sides to move synchronously along the guide grooves 2043 via the forward and reverse threads. After sliding, the adjusting blocks 2042 drive each guide wheel in the guide wheel assembly 201 to deflect via a short rod or hinge mechanism. The buffer stop 2045 at the end of the limiting slider 2044 effectively controls the displacement stroke. When the stone deviates and generates lateral force, the guide wheel assembly 201 drives the floating support 202 to move laterally, and the swing arm 2032 rotates to stretch the spring 2031, forming a reset force. By rotating the screw drive assembly 2041, the opening and closing angle of the guide wheel assembly 201 can be actively adjusted, achieving dynamic control of the correction range.

[0040] During the movement of the floating support 202, the limiting slider 2044 slides along the guide groove 2043, and the buffer block 2045 absorbs impact energy through deformation to prevent structural overload. This composite correction mode of passive response and active control can achieve high-precision dynamic correction of the conveyor belt 101, significantly reducing the risk of belt misalignment.

[0041] The wear-resistant idler roller assembly 3 includes a floating roller 301, a linkage mechanism 302, and an annular rubber layer 303. The annular rubber layer 303 covering the surface of the floating roller 301 has raised stripes 3031 and guide grooves 3032. The linkage mechanism 302 consists of a lifting arm 3021, a support base 3022, a guide pin 3024, and a compression spring 3025. One end of the lifting arm 3021 is hinged to the bearing seat of the floating roller 301, and the other end is sleeved with the guide pin 3024 through a round hole 3023 to achieve vertical sliding. The compression spring 3025 is sleeved on the outside of the guide pin 3024 and abuts against the lifting arm 3021. When the stone is pressed down, the floating roller 301 drives the lifting arm 3021 to sink along the guide pin 3024, and the compression spring 3025 contracts to buffer the impact load; after unloading, the spring rebounds and pushes the floating roller 301 to reset; the raised stripes 3031 reduce wear by dispersing the contact pressure, and the guide groove 3032 guides the debris to slide off simultaneously. Combined with the adaptive structure, the dynamic wear of the conveyor belt 101 is significantly reduced.

[0042] A cleaning scraper 4 is located at the discharge end of the conveyor belt 101 and includes an adjustable bracket 401 and a flexible scraper 402. The adjustable bracket 401 is connected to the frame 1 by bolts and can adjust the scraper's contact pressure. The guide strip 1031 of the side baffle 103 extends to the discharge end to form a continuous limiting boundary. When the conveyor belt 101 is running, the flexible scraper 402 continuously scrapes away surface debris, and the adjustable bracket 401 can dynamically compensate for scraper wear. The guide strip 1031 maintains positional constraint in the discharge section to prevent the stone end from shifting. The debris generated during cleaning is discharged in a concentrated manner through the guide groove 3032 to avoid accumulation and blockage. The synergistic effect of cleaning and limiting functions ensures the efficient and continuous operation of the conveyor belt 101.

Furthermore, the surface of the tension spring 2031 is covered with an anti-rust coating, and elastic buffer blocks are provided at both ends to reduce vibration and impact.
