Description

Technical Field

[0001] This invention relates to the field of automated production equipment for abrasives, specifically to a continuous traction conveying device for the production of flap wheels. Background Technology

[0002] In the automated production process of flap wheels, pre-cut discrete rectangular substrates (such as abrasive sheets) need to be stacked tightly on their sides into material columns, which are then continuously conveyed to subsequent gluing or assembly processes. In existing technologies, a pusher cylinder or a rear-mounted mechanical pusher is typically used within a slicing machine. In a straight U-shaped groove or flat-bottomed guide rail, a single rear-mounted thrust pushes the material column forward. As the conveying distance in the automated production line increases, the sliding friction resistance between the material column and the sidewalls and bottom of the guide rail accumulates non-linearly and exponentially. When the resistance exceeds a critical value, the single rear-mounted thrust easily leads to stress imbalance within the material column, resulting in… The buckling instability can lead to arching, folding, or even complete jamming, limiting the continuous and stable conveying distance of existing equipment. Furthermore, the rectangular substrate inevitably generates fine abrasive dust during the slicing process. In a straight-line pushing state, the substrate is compressed together, and this dust is firmly trapped deep within the substrate's gaps, lacking release space. As conveying continues, the trapped dust falls and deposits on the guide rail support surface, forming abrasive media (i.e., abrasive wear). This not only exacerbates the sliding friction coefficient along the path, further increasing the risk of jamming, but also causes wear on the guide rail surface, reducing the equipment's lifespan and transmission efficiency. Summary of the Invention

[0003] To address the aforementioned issues, a continuous traction conveying device for flap wheel production is provided. By coordinating the active pressing drive of the flexible traction belt with the arc-shaped section supporting the guide rail, the conveying distance of the equipment is increased. The flexible traction belt distributes the thrust along the path through static friction, effectively limiting the degree of freedom of the material column to arch upwards. When the material column passes through the arc section, the rectangular substrate at its bottom is forcibly opened to release dust, reducing conveying friction resistance and guide rail wear, and ensuring conveying stability.

[0004] To address the problems of existing technologies, this invention provides a continuous traction conveying device for flap wheel production, used for continuously conveying a material column composed of multiple discrete rectangular substrates stacked tightly on their sides. The device includes: a support guide rail extending along the conveying direction, comprising two symmetrically arranged L-shaped components with a longitudinally penetrating dust-collecting gap between their support surfaces; the support guide rail includes a downwardly concave arc segment in the conveying direction for guiding the material column along the concave arc trajectory; a traction mechanism positioned directly above the support guide rail, the traction mechanism having a flexible traction belt with a concave running trajectory adapted to the arc segment; the flexible traction belt presses downward against the top of the material column, driving the material column forward along the support guide rail with continuously rotating static friction; under the combined guidance of the pressing drive of the flexible traction belt and the arc segment, when the material column passes through the arc segment, the adjacent rectangular substrates at its bottom are spread apart to form a dust-collecting micro-slit.

[0005] Preferably, the traction mechanism further includes a plurality of support rollers disposed on the inner side of the flexible traction belt, the plurality of support rollers being divided into pressure-holding rollers and cam rollers with protruding ridges on their outer peripheral surfaces; the pressure-holding rollers and the cam rollers are arranged alternately along the trajectory of the arc segment.

[0006] Preferably, a conductive, antistatic, and wear-resistant strip is fixedly provided on the support surface of the support rail, and the conductive, antistatic, and wear-resistant strip is grounded to dissipate the static charge generated during the conveying process.

[0007] Preferably, the supporting guide rail includes a horizontal straight section connected to both ends of the arc segment, and the junction of the horizontal straight section and the arc segment is provided with a transition section with gradually changing curvature.

[0008] Preferably, the traction mechanism is provided with a floating component at the feeding end; the floating component causes the flexible traction belt at the feeding end to deflect upward to form a gradually expanding flared mouth, and the working surface of the flexible traction belt in contact with the material column is coated with an elastic differential absorption layer.

[0009] Preferably, a fixed frame and a sliding frame are respectively provided on the two L-shaped components supporting the guide rail. A screw drive is connected to the outside of the sliding frame to drive the sliding frame to move laterally to adjust the width of the conveying channel of the support guide rail.

[0010] Preferably, the sliding frame includes a movable frame driven by the lead screw drive member and a support frame mounted on the L-shaped member. An elastic member is connected between the support frame and the movable frame to provide the support frame with an elastic contraction force that presses against the L-shaped member.

[0011] Preferably, a sensor for monitoring the distance between the movable frame and the support frame is also provided.

[0012] Preferably, elastic baffles extending inward toward the channel are symmetrically provided at the discharge end of the supporting guide rail.

[0013] Preferably, the width of the supporting surface of the two L-shaped components is less than one-third of the width of the rectangular substrate; and the dust collection gap is connected to a dust collection device directly below the arc-shaped section.

[0014] The advantages of this invention compared to the prior art are: 1. This invention combines the active pressing drive of the flexible traction belt with the arc-shaped section of the supporting guide rail to increase the conveying distance of the equipment. The flexible traction belt distributes the thrust along the path through static friction, effectively limiting the freedom of the material column to arch upwards. At the same time, under the joint guidance of the flexible traction belt and the arc-shaped section, when the material column passes through the concave arc trajectory, the adjacent rectangular substrate at its bottom is forced open by the geometric angle effect, naturally forming dust removal micro-slits. This effectively releases the dust trapped deep in the gaps and removes the abrasive media on the guide rail support surface, thereby reducing the conveying friction resistance and guide rail wear, and ensuring the stability of long-distance conveying.

[0015] 2. In this invention, a pressure-holding roller and a cam roller with convex ridges are staggered on the inner side of the flexible traction belt. While the pressure-holding roller maintains the basic anti-arching downward pressure, the rotating cam roller uses its outer circumferential convex ridges to periodically push the traction belt outward, applying high-frequency micro-amplitude pulsating downward pressure to the material column. This allows the material column to simultaneously receive mechanical excitation from the top at the moment the bottom dust discharge micro-slit opens, forming a synergistic physical dust discharge effect. This forces highly adhesive micro-dust to fall into the dust drop gap, further reducing resistance during the conveying process.

[0016] 3. This invention adds a gradually changing curvature transition section at the junction of the horizontal straight section and the concave arc section of the supporting guide rail. This transition section eliminates the rigid inflection point caused by the abrupt change in the track trajectory, so that the tilting posture of the material column can be linearly and smoothly transitioned when entering and leaving the concave area. This avoids the instantaneous cornering, jamming and stress concentration of the material caused by the discontinuous transition, and ensures the seamless connection of the material between the arc section and the horizontal straight section. This provides a reliable guarantee for solving the problem of jamming in long-distance continuous conveying. Attached Figure Description

[0028] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1 , Figure 4 , Figure 5 , Figures 7 to 10As shown: A continuous traction conveying device for flap wheel production, used for continuously conveying a material column 3 formed by multiple discrete rectangular substrates 31 stacked tightly on their sides, includes: a supporting guide rail 1 extending along the conveying direction, the supporting guide rail 1 including two symmetrically arranged L-shaped components 11, and a longitudinally penetrating dust collection gap formed between the supporting surfaces of the two L-shaped components 11; the supporting guide rail 1 includes a downwardly concave arc segment 12 in the conveying direction, used to guide the material column 3 to run along the concave arc trajectory; a traction mechanism 2, provided with Positioned directly above the supporting guide rail 1, the traction mechanism 2 has a flexible traction belt 21 with a concave running trajectory adapted to the arc segment 12; the flexible traction belt 21 presses downward against the top of the material column 3, driving the material column 3 forward along the supporting guide rail 1 with continuous rotational static friction; under the combined guidance of the pressing drive of the flexible traction belt 21 and the arc segment 12, when the material column 3 passes through the arc segment 12, the adjacent rectangular substrates 31 at its bottom are spread apart to form a dust removal micro-slit.

[0030] In the automated production process of flap wheels, discrete rectangular substrates 31 are usually stacked tightly on their sides to form long strip-shaped material columns 3. Traditional conveying methods often rely solely on the end thrust of the previous slicing process. As the conveying distance increases, the sliding friction resistance between the material column 3 and the sidewall of the guide rail accumulates nonlinearly, easily causing the material column 3 to buckle, arch, or jam. At the same time, the fine dust generated by material cutting is tightly trapped in the gaps of the upright rectangular substrates 31, aggravating mechanical wear and limiting the conveying distance of the material column 3. To fundamentally solve the above technical problems, the present invention provides a supporting guide rail 1 composed of two symmetrically arranged L-shaped components 11, with a longitudinally penetrating dust collection gap between the supporting surfaces of the two L-shaped components 11. The supporting guide rail 1 includes a downwardly concave arc segment 12 in the conveying direction, which, together with the traction mechanism 2 located directly above, has a flexible traction belt 21 that exhibits a similar shape to the guide rail 1. The concave running trajectory of the arc segment 12 is adapted to the material column 3. Under normal operating conditions, the flexible traction belt 21 presses down on the top of the material column 3, using static friction as the active traction power source. This reduces the pushing resistance along the way. When the material column 3 is pressed by the flexible traction belt 21 and runs along the arc segment 12, the adjacent rectangular substrate 31 at the bottom of the material column 3 is forced open by the geometric angle effect due to the concave curvature of the running trajectory. This naturally forms a dust discharge micro-gap, allowing the stubborn internal dust that is trapped to be effectively discharged through the dust drop gap. This avoids the sharp increase in resistance caused by dust accumulation. This conformal traction breaks through the physical distance bottleneck of traditional single-end pushing conveying, eliminates the arching and jamming phenomenon caused by the buckling of the material column 3 under pressure in long-distance conveying channels, and improves the smoothness of continuous conveying. This makes the layout length of the automated production line no longer limited by the thrust limit.

[0031] like Figure 1 , Figures 4 to 6 and Figure 10 As shown: The traction mechanism 2 also includes a plurality of support rollers 22 disposed on the inner side of the flexible traction belt 21. The plurality of support rollers 22 are divided into pressure holding rollers 221 and cam rollers 222 with protruding ridges 223 on their outer peripheral surfaces. The pressure holding rollers 221 and the cam rollers 222 are arranged alternately along the trajectory of the arc segment 12.

[0032] On top of the basic dynamic dust removal framework, in order to better handle highly adhesive dust, the multiple support rollers 22 on the inner side of the flexible traction belt 21 are divided into a smooth pressure roller 221 and a cam roller 222 with a raised ridge 223 on its outer circumference. Above the arc segment 12, the pressure roller 221 and the cam roller 222 are arranged in an alternating pattern. The pressure roller 221 is responsible for providing stable downward pressure to prevent the material from arching, while the rotating cam roller 222 uses its raised ridge 223 to periodically push the flexible traction belt 21 outward. Through this alternation, a high-frequency, micro-amplitude pulsating downward pressure is applied to the material column 3, which is equivalent to mechanically vibrating it while the bottom dust removal micro-slit is opened, thus improving the dust removal efficiency. As a preferred embodiment, in order to avoid the bridging effect between two adjacent support rollers 22 of the flexible traction belt 21, which would cause the pulsating downward pressure to be laterally distributed by the belt tension, the center distance between two adjacent support rollers 22 is preferably set to 1.1 to 1.5 times the outer diameter of the support roller 22. This spacing ratio forms a dynamic balance at the mechanical level, which can effectively limit the amount of sag of the flexible traction belt 21 between the pressure rollers 221, prevent the material column 3 from arching upward, and leave sufficient deformation space for the flexible traction belt 21 when it is hit by the convex edge 223 of the cam roller 222, thereby ensuring that the high-frequency micro-amplitude pulsating impact force can penetrate the belt and be transmitted to the rectangular substrate 31 at the bottom.

[0033] like Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown: A conductive antistatic wear-resistant strip is fixedly provided on the support surface of the support rail 1. The conductive antistatic wear-resistant strip is grounded to dissipate the static charge generated during the conveying process.

[0034] To address the issue of dust accumulation caused by electrostatic adsorption in polymer materials during frictional traction, conductive antistatic wear-resistant strips are fixedly installed on the support surfaces of the two L-shaped components 11. These strips are made of self-lubricating materials such as ultra-high molecular weight polyethylene wear-resistant layers doped with carbon nanotubes or special polytetrafluoroethylene composite boards (not shown in the figure). They are connected to the workshop's main ground wire via copper braided wires to maintain a low-impedance grounding setting. This electrostatic dissipation network can conduct frictional charges to the ground in real time, cutting off the electric field source for dust adsorption at the material level. This reduces the coefficient of frictional friction along the conveying process, alleviates mechanical wear on the bottom support rail 1, extends the service life of the rail consumables, and effectively reduces the continuous operating load of the drive motor of the traction mechanism 2, thereby improving the overall power transmission efficiency of the machine.

[0035] like Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown: The supporting guide rail 1 includes a horizontal straight section 121 connected to both ends of the arc segment 12, and a transition section 122 with gradually changing curvature is provided at the junction of the horizontal straight section 121 and the arc segment 12.

[0036] To further ensure the stability of the material column 3 under high-speed continuous traction and prevent rigid impact and corner biting, the supporting guide rail 1 includes not only the arc section 12, but also the horizontal straight sections 121 at both ends. At the junction of the horizontal straight section 121 and the arc section 12, a transition section 122 with gradually changing curvature is specially set to guide the tilting posture of the material column 3 to a linear and smooth transition.

[0037] like Figure 1 , Figures 3 to 8 and Figure 10 As shown: The traction mechanism 2 is provided with a floating component 211 at the feeding end; the floating component 211 causes the flexible traction belt 21 at the feeding end to deflect upward to form a gradually expanding horn mouth, and the flexible traction belt 21 is combined with an elastic differential absorption layer 212 on the working surface of the material column 3.

[0038] When the material column 3 initially enters the traction area, the floating component 211 configured at the feeding end of the traction mechanism 2 causes the flexible traction belt 21 to deflect upward. The floating component 211 can be configured as a cantilever rocker arm mechanism with a pre-tension spring. By forming a gradually expanding horn at the inlet, the gradually expanding horn converts the instantaneous impact of the material entering into a gentle wedge-shaped progressive downward pressure, effectively preventing the collapse of the front rectangular substrate 31. As a preferred embodiment, the flexible traction belt 21 has an elastic differential absorption layer 212 on the working surface that contacts the material column 3 downward. For example, a high-density polyurethane microporous foam material is used. It can adaptively absorb the objective height and thickness tolerances between the discrete rectangular substrates 31, ensuring the uniform transmission of normal pressure, avoiding the chain collapse and unplanned shutdown of the material column 3 caused by individual jumps, ensuring the stability of the material column 3 in the high-speed, high-throughput conveying process, and reducing the scrap rate.

[0039] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figures 7 to 9 As shown: The two L-shaped components 11 of the supporting guide rail 1 are respectively provided with a fixed frame 13 and a sliding frame 14. The outer side of the sliding frame 14 is connected to a screw drive 1411, which is used to drive the sliding frame 14 to move laterally to adjust the width of the conveying channel of the supporting guide rail 1.

[0040] The sliding frame 14 includes a movable frame 141 driven by the lead screw drive 1411, and a support frame 142 mounted on the L-shaped member 11. An elastic member 1421 is connected between the support frame 142 and the movable frame 141 to provide the support frame 142 with an elastic contraction force that presses against the L-shaped member 11.

[0041] A sensor 1412 for monitoring the distance between the movable frame 141 and the support frame 142 is also provided.

[0042] To ensure compatibility with substrates of different widths in flexible manufacturing and to establish a safety defense mechanism under extreme working conditions, fixed frames 13 and sliding frames 14 are respectively set on both sides of the supporting guide rail 1. By configuring a screw drive component 1411 such as a trapezoidal screw or a servo electric cylinder, the sliding frame 14 can be driven to move laterally as a whole, smoothly adjusting the width between the two L-shaped components 11. On this basis, in order to deal with the risk of instantaneous jamming and explosion caused by waste material mixing or material folding, the sliding frame 14 adopts a double-layer flexible unloading structure, which includes a moving frame 141 directly driven by the screw drive component 1411, and a support frame 142 actually installed on the L-shaped component 11. An elastic component 1421 is connected between the two. The elastic component 1421 can be specifically configured as a cylindrical helical spring, a disc spring group, or a high-elasticity rubber block. Under normal conveying conditions, the elastic element 1421 is in a pre-tightened state, continuously pressing against the moving frame 141 and the support frame 142, thereby providing the support frame 142 and the L-shaped component 11 fixed thereto with an elastic contraction force that presses against the inside of the channel (i.e. towards the material column 3), maintaining the predetermined channel conveying width. At the same time, a pre-tightening force adjusting bolt (not shown in the figure) can be further configured on the moving frame 141 to change the initial compression of the elastic element 1421, thereby achieving fine adjustment of the magnitude of the elastic contraction force. By configuring a sensor 1412 between the moving frame 141 and the support frame 142, the sensor 1412 can preferably be a high-precision micro switch, limit switch, proximity switch or laser rangefinder. Once distorted waste material is accidentally mixed into the conveying channel or the rectangular substrate 31 is folded and causes instantaneous jamming, the abnormally surged lateral compressive stress will act in the opposite direction on the L-shaped component 11, and force the support frame 142 to overcome the thrust of the elastic element 1421 and float outward. At this time, the sensor 1412 configured between the moving frame 141 and the support frame 142 will keenly detect the displacement signal of the shortening of the relative distance between the two, and immediately output a chain emergency stop signal to the central control unit, cutting off the drive motor power of the traction mechanism 2 in a short time. This safety defense mechanism gives the conveyor line a high fault tolerance, avoids destructive accidents such as motor overload burnout, breakage of the flexible traction belt 21 or material squeezing and flying, and ensures the safety of the core transmission components.

[0043] like Figure 1 , Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown: at the discharge end of the supporting guide rail 1, elastic baffles 15 extending into the channel are symmetrically provided.

[0044] At the discharge end of the supporting guide rail 1, due to the release of traction force, the material column 3 is prone to domino-like collapse. For this reason, elastic baffles 15 extending into the inner side of the channel are symmetrically provided. The elastic baffles 15 (which can also be configured as damping brushes) apply controllable reverse frictional resistance to the passing material column 3, establishing a stable axial back pressure, so that the substrate in the entire arc section 12 always maintains a tight stacked state.

[0045] like Figure 1 , Figure 4 , Figure 5 and Figures 7 to 9 As shown: the width of the supporting surface of the two L-shaped components 11 is less than one-third of the width of the rectangular substrate 31; and the dust collection gap is connected to a dust collection device 16 directly below the arc-shaped segment 12.

[0046] The width of the supporting surface of the two L-shaped components 11 is designed to be less than one-third of the width of the rectangular substrate 31 in order to maximize the exposure of the bottom of the rectangular substrate 31. At the same time, the dust collection gap can be connected to the dust collection equipment 16, such as a negative pressure dust extraction fan or a gravity dust collection hopper, directly below the arc section 12, to achieve centralized and active cleaning of dust.

[0047] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
