Technical Field
[0001] This invention belongs to the field of sheet material processing and conveying technology, specifically a continuous conveying device for processing lightweight polyvinyl chloride composite sheets. Background Technology
[0002] Lightweight polyvinyl chloride (PVC) composite panels are a new type of panel material that combines lightweight, high strength, and multifunctionality with PVC as the main matrix material, achieved through material modification, structural optimization, or composite process design. Its core objective is to significantly reduce material density while maintaining or improving key indicators such as mechanical properties and weather resistance, thereby meeting application requirements such as energy conservation, environmental protection, and convenient transportation and installation.
[0003] Currently, lightweight polyvinyl chloride (PVC) composite sheets are commonly transported using conveyor rollers such as metal or rubber rollers during processing. However, due to the low density and light weight of the material, insufficient contact pressure between the conveyor roller and the sheet is prone to occur during transport. This leads to the roller spinning idly and generating unexpected sliding friction with the sheet surface. This condition not only significantly reduces the conveying efficiency of the sheet and causes production line imbalance, but also causes scratches, burrs, and other wear defects on the sheet surface due to repeated friction, thus affecting the dimensional accuracy and surface quality of the final product. This problem is further aggravated in continuous production scenarios, leading to secondary problems such as sheet misalignment and stacking. Therefore, a continuous conveying device for processing lightweight polyvinyl chloride composite sheets is proposed. Summary of the Invention
[0004] To address the problems mentioned in the background art, this invention provides a continuous conveying device for processing lightweight polyvinyl chloride (PVC) composite sheets. This device solves the problem that during the conveying process of lightweight PVC composite sheets, the weight of the sheets easily leads to insufficient contact pressure between the conveying rollers (such as metal rollers or rubber rollers) and the sheets, causing idling and sliding friction. This not only reduces conveying efficiency but may also cause surface wear (such as scratches and burrs), affecting product precision and quality.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a continuous conveying device for processing lightweight polyvinyl chloride composite sheets, comprising a base frame and lightweight polyvinyl chloride composite sheets, wherein rubber transmission rollers for conveying lightweight polyvinyl chloride composite sheets are equidistantly arranged on the base frame, and further comprising:
[0006] A pressure-applying assembly, mounted on the top of the base frame, is used to spray airflow to apply downward pressure to the lightweight polyvinyl chloride composite sheet as it moves on the rubber drive roller.
[0007] A correction assembly is mounted on both sides of the pressure application assembly and located between two adjacent rubber drive rollers;
[0008] An adjustment component, which is mounted on the calibration component;
[0009] The pressure application component includes a support frame fixed to the top of the base frame, a crossbeam frame is installed on the support frame, and air injection components are installed at equal intervals at the bottom of the crossbeam frame through a connecting frame. Air injection holes are opened at equal intervals at the bottom of the air injection components.
[0010] The bottom of the support frame is equipped with a first air injection pipe, which is connected to the air injection component through a first connecting pipe, and the top of the first air injection pipe is connected to the air injection device through a connecting pipe.
[0011] The air injection component corresponds to the rubber transmission roller, and the air injection hole is vertically aligned with the dot of the cross-section of the rubber transmission roller.
[0012] Preferably, the lightweight PVC composite sheet is conveyed by a rotating rubber drive roller, and the lightweight PVC composite sheet passes sequentially between the rubber drive roller and the air injection component, where a strong airflow is ejected through the air injection hole to apply downward pressure to the lightweight PVC composite sheet.
[0013] Preferably, the calibration assembly includes a second air injection pipe mounted on the support frame, the end of the second air injection pipe being connected to an air injection device;
[0014] A second connecting pipe is installed on the second air injection pipe, and an air jet is movably sleeved at the end of the second connecting pipe. The second connecting pipe communicates with the air jet through an air inlet, and an air jet hole is opened at the end of the air jet.
[0015] Preferably, the horizontal axis of the jetting element and the end nozzle is higher than the top of the outer circumference of the rubber drive roller;
[0016] The jetting element is disposed between two adjacent rubber drive rollers, and the correction assembly is symmetrically arranged with the middle of the rubber drive roller as a reference.
[0017] Preferably, the airflow from the two jets has the same intensity, and a cross support frame is fixed to the outside of the second connecting pipe;
[0018] The lightweight PVC composite sheet is conveyed by a rubber transmission roller, and a strong airflow is ejected through the nozzles at the ends of two symmetrically arranged jet components to impact both sides of the lightweight PVC composite sheet.
[0019] Preferably, when the lightweight PVC composite sheet deviates during its movement on the rubber drive roller, one side of the lightweight PVC composite sheet gradually moves closer to the jet nozzle at one end, while the other side of the lightweight PVC composite sheet gradually moves away from the jet nozzle at the other end. The end of the lightweight PVC composite sheet that moves closer to the jet nozzle at one end shortens the distance between the side of the lightweight PVC composite sheet and the nozzle, while the other side of the lightweight PVC composite sheet increases the distance between itself and the jet nozzle.
[0020] Preferably, during the process of adjusting the angle of the lightweight PVC composite sheet by ejecting airflow through the jetting component, a strong airflow is ejected by the air injection component to apply downward pressure to the lightweight PVC composite sheet moving on the rubber drive roller.
[0021] Preferably, a C-shaped stabilizing frame is fixedly mounted on the outside of the jet component, a transmission rod is fixedly mounted on the bottom of the C-shaped stabilizing frame via a docking frame, a spiral groove is opened on the outside of the transmission rod, a C-shaped support frame is fixedly mounted on the inner wall of the base frame, and a transmission plate is movably mounted on the top of the C-shaped support frame via a fixing frame.
[0022] Preferably, the transmission plate is movably sleeved on the outside of the transmission rod, and the inner wall of the transmission plate is provided with a sliding block that is movably engaged with the spiral groove;
[0023] The bottom of the C-shaped stabilizer is provided with a rectangular through slot, the upper end of the transmission plate passes through the rectangular through slot, and the upper end of the transmission plate is higher than the top of the outer circumference of the rubber transmission roller.
[0024] Preferably, the inner diameter of the inner wall of the jet component gradually increases from the end away from the second air injection pipe, and the outer diameter of the end of the second connecting pipe located inside the jet component gradually increases from the end away from the second air injection pipe.
[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0026] This invention injects gas into a first gas injection pipe by connecting a pipe to a gas injection device. The gas enters the first gas injection pipe and the gas injection component, and is ejected through the gas injection hole. The lightweight PVC composite sheet passes between the rubber drive roller and the gas injection component. The strong airflow ejected through the gas injection hole acts on the top of the lightweight PVC composite sheet, thereby increasing the downward pressure on the lightweight PVC composite sheet. This, in turn, increases the contact pressure between the rubber drive roller and the lightweight PVC composite sheet, preventing the rubber drive roller from spinning idly during rotation, which would cause scratches, burrs, and other wear on the surface of the lightweight PVC composite sheet. At the same time, it ensures the stability of continuous conveying of the lightweight PVC composite sheet.
[0027] This invention utilizes a rubber drive roller to transport and process lightweight polyvinyl chloride (PVC) composite sheets. During the movement of the rubber drive roller, airflow from the second air injection pipe enters the second connecting pipe, passes through the air inlet, and enters the jetting component. It then passes through the cross support frame and exits through the nozzle at the end of the jetting component. Because the horizontal axis of the nozzle at the end of the jetting component is higher than the top of the outer circumference of the rubber drive roller, the strong airflow impacts the side of the lightweight PVC composite sheet. Simultaneously, since the jetting components are symmetrically positioned at both ends of the rubber drive roller, the opposing ends of the two jetting components emit airflow of consistent intensity. This consistent airflow at both ends ensures that the lightweight PVC composite sheet remains in the center of the rubber drive roller, preventing deviation during movement that could affect normal transport.
[0028] In this invention, during the conveying of lightweight PVC composite sheets using a rubber transmission roller, the offset of the lightweight PVC composite sheet pushes the transmission plate to rotate around the transmission rod as its central axis. Through the cooperation of the sliding block on the inner wall of the transmission plate and the spiral groove, the transmission rod, the C-shaped stabilizer, and the jetting component move towards the second air injection pipe, thereby shortening the distance between the end of the inner wall of the jetting component and the end of the second connecting pipe, thus reducing the gap between the inner wall of the jetting component and the second connecting pipe, increasing the airflow intensity, and thus achieving the correction of the lightweight PVC composite sheet by increasing the airflow intensity, avoiding the phenomenon of jamming during the conveying of the lightweight PVC composite sheet.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] like Figures 1 to 10 As shown, the present invention provides a continuous conveying device for processing lightweight polyvinyl chloride composite sheets, including a base frame 1 and lightweight polyvinyl chloride composite sheets 6. Rubber transmission rollers 2 for conveying the lightweight polyvinyl chloride composite sheets 6 are equidistantly arranged on the base frame 1. The device also includes:
[0042] Pressure application component 3, which is installed on the top of the base frame 1, is used to spray airflow to apply downward pressure to the lightweight polyvinyl chloride composite sheet 6 as it moves on the rubber drive roller 2.
[0043] The correction component 5 is installed on both sides of the pressure application component 3 and is located between two adjacent rubber drive rollers 2;
[0044] Adjustment component 4 is mounted on calibration component 5;
[0045] The pressure application component 3 includes a support frame 31 fixed to the top of the base frame 1. A crossbeam frame 33 is installed on the support frame 31. An air injection component 34 is installed at equal intervals at the bottom of the crossbeam frame 33 through a connecting frame 32. An air injection hole 38 is opened at equal intervals at the bottom of the air injection component 34.
[0046] The bottom of the support frame 31 is equipped with a first air injection pipe 35, which is connected to the air injection component 34 through a first connecting pipe 37, and the top of the first air injection pipe 35 is connected to the air injection device through a connecting pipe 36.
[0047] The air injection component 34 is aligned with the rubber transmission roller 2, and the air injection hole 38 is vertically aligned with the dot of the cross section of the rubber transmission roller 2.
[0048] The lightweight PVC composite sheet 6 is conveyed by the rotating rubber drive roller 2. The lightweight PVC composite sheet 6 passes between the rubber drive roller 2 and the air injection component 34 in sequence. A strong airflow is ejected through the air injection hole 38 to apply downward pressure to the lightweight PVC composite sheet 6.
[0049] The lightweight PVC composite sheet 6 is conveyed and processed by the synchronous rotation of the rubber transmission roller 2 driven by the driving equipment. The connecting pipe 36 is connected to the air injection equipment to inject air into the first air injection pipe 35. The gas enters the first air injection pipe 35 and the air injection component 34, and is ejected through the air injection hole 38. The strong airflow ejected through the air injection hole 38 acts on the top of the lightweight PVC composite sheet 6 between the rubber transmission roller 2 and the air injection component 34, thereby increasing the downward pressure on the lightweight PVC composite sheet 6 and thus increasing the contact between the rubber transmission roller 2 and the lightweight PVC composite sheet 6. Pressure is applied to prevent the rubber drive roller 2 from spinning idly during rotation, which could cause scratches, burrs, or other wear on the surface of the lightweight PVC composite sheet 6. This also ensures the stability of continuous conveying of the lightweight PVC composite sheet 6. Since the air injection element 34 corresponds to the rubber drive roller 2, and the air injection hole 38 is vertically aligned with the dot of the rubber drive roller 2's cross-section, the pressure applied during conveying of the lightweight PVC composite sheet 6 by the rubber drive roller 2 prevents deformation and structural damage caused by strong airflow, thus ensuring the quality of the lightweight PVC composite sheet 6 processing.
[0050] like Figures 3-10 As shown, the calibration assembly 5 includes a second air injection pipe 51 mounted on the support frame 31, and the end of the second air injection pipe 51 is connected to the air injection device.
[0051] The airflow pressure in the first air injection tube 35 and the second air injection tube 51 is the same;
[0052] A second connecting pipe 52 is installed on the second air injection pipe 51. An air jet 53 is movably sleeved at the end of the second connecting pipe 52. The second connecting pipe 52 communicates with the air jet 53 through an air inlet 54. An air jet hole is opened at the end of the air jet 53.
[0053] The horizontal axis of the jetting component 53 and the end nozzle is higher than the top of the outer circumference of the rubber drive roller 2;
[0054] The jetting element 53 is disposed between two adjacent rubber transmission rollers 2, and the correction assembly 5 is symmetrically disposed with reference to the middle part of the rubber transmission roller 2;
[0055] The two jets 53 eject airflow with the same intensity, and the second connecting pipe 52 is externally fixed with a cross support frame 55;
[0056] The lightweight PVC composite board 6 is conveyed by the rubber transmission roller 2 and a strong airflow is ejected through the nozzles at the ends of two symmetrically arranged jet components 53 to impact both sides of the lightweight PVC composite board 6.
[0057] When the lightweight PVC composite sheet 6 deviates during its movement on the rubber transmission roller 2, one side of the lightweight PVC composite sheet 6 gradually moves closer to the jet nozzle 53 at one end, while the other side of the lightweight PVC composite sheet 6 gradually moves away from the jet nozzle 53 at the other end. The end of the lightweight PVC composite sheet 6 that moves closer to the jet nozzle 53 at one end shortens the distance between the side of the lightweight PVC composite sheet 6 and the nozzle, while the other side of the lightweight PVC composite sheet 6 increases the distance between it and the jet nozzle 53.
[0058] During the process of adjusting the angle of the lightweight PVC composite sheet 6 by ejecting airflow through the jetting component 53, the air injection component 34 ejects a strong airflow to apply downward pressure to the lightweight PVC composite sheet 6 moving on the rubber transmission roller 2.
[0059] The lightweight PVC composite sheet 6 is conveyed and processed by the rubber transmission roller 2 through the connection of the air injection device and the second air injection pipe 51. During the movement of the rubber transmission roller 2, the airflow in the second air injection pipe 51 enters the second connecting pipe 52, passes through the air inlet 54 and enters the jetting element 53, and passes through the cross support frame 55 and is discharged through the nozzle at the end of the jetting element 53. Since the horizontal axis of the nozzle at the end of the jetting element 53 is higher than the top of the outer circumference of the rubber transmission roller 2, the strong airflow impacts the side of the lightweight PVC composite sheet 6. At the same time, since the jetting elements 53 are symmetrically arranged at both ends of the rubber transmission roller 2, the opposite ends of the two jetting elements 53 spray airflow of the same intensity. Through the consistent airflow at both ends, the lightweight PVC composite sheet 6 is always located in the middle of the rubber transmission roller 2, avoiding the lightweight PVC composite sheet 6 from shifting during the movement and affecting normal conveying.
[0060] Simultaneously, when the lightweight PVC composite sheet 6 deviates during its movement on the rubber drive roller 2, since the jet nozzle 53 is located between two adjacent rubber drive rollers 2, one side of the lightweight PVC composite sheet 6 gradually moves closer to the jet nozzle 53 at one end, while the other side gradually moves away from the jet nozzle 53 at the other end. Because the airflow intensity emitted by the two jet nozzles 53 is consistent, when the lightweight PVC composite sheet 6 moves closer to the end of the jet nozzle 53, the distance between the side of the lightweight PVC composite sheet 6 and the nozzle is shortened, increasing the intensity of the airflow impacting the side of the lightweight PVC composite sheet 6. Meanwhile, the distance between the other side of the lightweight PVC composite sheet 6 and the jet nozzle 53 is increased, thereby reducing the intensity of the airflow impacting the other side of the lightweight PVC composite sheet 6. In this way, the movement trajectory of the lightweight PVC composite sheet 6 on the rubber drive roller 2 can be adjusted by the consistent airflow emitted by the two jet nozzles 53, thus avoiding the phenomenon of deviation.
[0061] Meanwhile, as the angle of the lightweight PVC composite sheet 6 is adjusted by the airflow ejected by the jetting component 53, the air injection component 34 simultaneously ejects a strong airflow to apply downward pressure to the lightweight PVC composite sheet 6 moving on the rubber transmission roller 2, so as to prevent the lightweight PVC composite sheet 6 from deforming or warping due to the airflow ejected by the jetting component 53.
[0062] like Figures 3-10 As shown, a C-shaped stabilizer 41 is fixedly mounted on the outside of the jet component 53. A transmission rod 43 is fixedly mounted on the bottom of the C-shaped stabilizer 41 through a docking frame 42. A spiral groove 44 is opened on the outside of the transmission rod 43. A C-shaped support frame 46 is fixedly mounted on the inner wall of the base frame 1. A transmission plate 45 is movably mounted on the top of the C-shaped support frame 46 through a fixing frame 47.
[0063] The distance between the two transmission plates 45 located at both ends of the rubber transmission roller 2 is greater than the width of the lightweight polyvinyl chloride composite sheet 6;
[0064] The transmission plate 45 is movably sleeved on the outside of the transmission rod 43, and the inner wall of the transmission plate 45 is provided with a sliding block that is movably engaged in the spiral groove 44.
[0065] The bottom of the C-type stabilizer 41 is provided with a rectangular through groove 48, the upper end of the transmission plate 45 passes through the rectangular through groove 48, and the upper end of the transmission plate 45 is higher than the top of the outer periphery of the rubber transmission roller 2.
[0066] The inner diameter of the end of the jet component 53 gradually increases from the end away from the second air injection pipe 51, and the outer diameter of the end of the second connecting pipe 52 located inside the jet component 53 gradually increases from the end away from the second air injection pipe 51.
[0067] During the conveying process of the lightweight PVC composite sheet 6 via the rubber drive roller 2, the lightweight PVC composite sheet 6 is biased towards one end of the rubber drive roller 2. At this time, the lightweight PVC composite sheet 6 pushes the drive plate 45 at one end to rotate around the drive rod 43 as the central axis. Through the cooperation of the sliding block on the inner wall of the drive plate 45 and the spiral groove 44, the drive rod 43, the C-shaped stabilizer 41 and the jet 53 move towards the second air injection pipe 51, thereby shortening the distance between the inner wall end of the jet 53 and the end of the second connecting pipe 52, thereby reducing the gap between the inner wall of the jet 53 and the second connecting pipe 52, increasing the airflow intensity, and thus achieving the correction of the lightweight PVC composite sheet 6 by increasing the airflow intensity, avoiding the phenomenon of jamming during the conveying process of the lightweight PVC composite sheet 6. When the lightweight PVC composite sheet 6 is separated from the drive plate 45, the jet 53, the C-shaped stabilizer 41, the drive rod 43 and the drive plate 45 are reset under the action of the airflow.
[0068] If the lightweight PVC composite sheet 6 does not deviate during the conveying process, it will not come into contact with the transmission plate 45. At this time, the jet component 53, the C-shaped stabilizer 41, the transmission rod 43 and the transmission plate 45 will be reset under the action of airflow.
[0069] Working principle and usage process of this invention:
[0070] The lightweight PVC composite sheet 6 is conveyed and processed by the synchronous rotation of the rubber transmission roller 2 driven by the drive equipment. The connecting pipe 36 is connected to the air injection equipment to inject air into the first air injection pipe 35. The gas enters the first air injection pipe 35 and the air injection component 34, and is ejected through the air injection hole 38. The lightweight PVC composite sheet 6 is subjected to the strong airflow ejected through the air injection hole 38 between the rubber transmission roller 2 and the air injection component 34, which acts on the top of the lightweight PVC composite sheet 6, thereby increasing the downward pressure on the lightweight PVC composite sheet 6, and thus increasing the pressure between the rubber transmission roller 2 and the lightweight PVC composite sheet 6. The contact pressure between the composite panels 6 prevents the rubber drive roller 2 from spinning freely during rotation, which would cause scratches, burrs, and other wear on the surface of the lightweight PVC composite panel 6. At the same time, it ensures the stability of continuous conveying of the lightweight PVC composite panel 6. Since the air injection component 34 corresponds to the rubber drive roller 2 and the air injection hole 38 is vertical to the dot of the cross section of the rubber drive roller 2, the lightweight PVC composite panel 6 is prevented from being deformed and its structure damaged by strong airflow during the conveying process of the lightweight PVC composite panel 6 by the rubber drive roller 2.
[0071] Simultaneously, the air injection device is connected to the second air injection pipe 51, and the lightweight PVC composite sheet 6 is conveyed and processed through the rubber transmission roller 2. During the movement of the rubber transmission roller 2, the airflow in the second air injection pipe 51 enters the second connecting pipe 52, passes through the air inlet 54, enters the jetting element 53, passes through the cross support frame 55, and is discharged through the nozzle at the end of the jetting element 53. Since the horizontal axis of the nozzle at the end of the jetting element 53 is higher than the top of the outer circumference of the rubber transmission roller 2, the strong airflow impacts the side of the lightweight PVC composite sheet 6. At the same time, since the jetting elements 53 are symmetrically arranged at both ends of the rubber transmission roller 2, the opposite ends of the two jetting elements 53 spray airflow of the same intensity. Through the consistent airflow at both ends, the lightweight PVC composite sheet 6 is always located in the middle of the rubber transmission roller 2, avoiding the lightweight PVC composite sheet 6 from shifting during the movement and affecting normal conveying.
[0072] When the lightweight PVC composite sheet 6 deviates during its movement on the rubber drive roller 2, because the jet nozzle 53 is located between two adjacent rubber drive rollers 2, one side of the lightweight PVC composite sheet 6 gradually moves closer to the jet nozzle 53 at one end, while the other side gradually moves away from the jet nozzle 53 at the other end. Since the airflow intensity from the two jet nozzles 53 is consistent, when the lightweight PVC composite sheet 6 approaches the end of the jet nozzle 53, the distance between the side of the lightweight PVC composite sheet 6 and the nozzle is shortened, increasing the intensity of the airflow from the jet nozzle 53 impacting the side of the lightweight PVC composite sheet 6. The distance between the other side of 6 and the jetting element 53 is increased, thereby reducing the intensity of the airflow impacting the other side of the lightweight PVC composite sheet 6. In this way, the movement trajectory of the lightweight PVC composite sheet 6 on the rubber transmission roller 2 can be adjusted by the airflow of the two jetting elements 53 with the same intensity, avoiding the phenomenon of deviation. At the same time, during the process of adjusting the angle of the lightweight PVC composite sheet 6 by the airflow of the jetting element 53, the air injection element 34 sprays a strong airflow to apply downward pressure to the lightweight PVC composite sheet 6 moving on the rubber transmission roller 2, so as to prevent the lightweight PVC composite sheet 6 from being deformed or warped by the airflow of the jetting element 53.
[0073] When the lightweight PVC composite sheet 6 experiences severe misalignment, it pushes the transmission plate 45 to rotate around the transmission rod 43 as the central axis. Through the cooperation of the sliding block on the inner wall of the transmission plate 45 and the spiral groove 44, the transmission rod 43, the C-shaped stabilizer 41, and the jet component 53 move towards the second air injection pipe 51. This shortens the distance between the end of the inner wall of the jet component 53 and the end of the second connecting pipe 52, thereby reducing the gap between the inner wall of the jet component 53 and the second connecting pipe 52 and increasing the airflow intensity. This increased airflow intensity then drives the correction of the lightweight PVC composite sheet 6.
