Description

Technical Field

[0001] This invention relates to the field of paper-faced gypsum board manufacturing equipment technology, specifically to a self-detection fixed-point cleaning system for gypsum board forming belts. Background Technology

[0002] With the development of the gypsum board industry, the market's requirements for the appearance quality of gypsum boards are also increasing. There are many factors that affect the appearance quality of gypsum boards, such as surface pitting and white gypsum marks on the paper surface.

[0003] The white plaster stains on the conveyor belt are mostly caused by lumps in the slurry (caking the protective paper and causing the slurry to leak onto the belt) or by slurry overflowing onto the belt during the pulling process. Residual slurry on the belt then stains the protective paper, resulting in defective sheets that affect the appearance. To reduce the production of these defective sheets, current technology often involves manual wiping or periodic high-pressure water washing of the belt. However, the belt is hundreds of meters long, making the cleaning process time-consuming, labor-intensive, and ineffective, easily disrupting production.

[0004] However, existing cleaning devices typically rinse the entire width of the conveyor belt, rather than focusing on cleaning plaster marks on the conveyor belt. Summary of the Invention

[0005] The purpose of this invention is to provide a self-detection fixed-point cleaning system for gypsum board forming conveyor belts, in order to solve the problem that the cleaning width of existing cleaning devices is not easy to adjust when cleaning conveyor belts, resulting in a mismatch between the cleaning width of the cleaning device and the width range of gypsum marks on the conveyor belt.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0007] This invention provides a self-detection fixed-point cleaning system for gypsum board forming conveyor belts, comprising: a cleaning device disposed below the conveyor belt head, the cleaning device using water flow to rinse the surface of the conveyor belt; a vision inspection device located upstream of the cleaning device and on the side of the conveyor belt, for detecting gypsum marks adhering to the conveyor belt; the vision inspection device includes a camera element, which collects information on the coverage width and length of the gypsum marks adhering to the conveyor belt and transmits image signals to a PLC controller for calculation; the running time is calculated based on the fixed distance between the cleaning device and the vision inspection device and the running speed of the conveyor belt, so that the cleaning device is activated at regular intervals after the vision inspection device detects gypsum marks; wherein, the cleaning device includes a cleaning pipe. One end of the cleaning pipe is open and connected to a water inlet hose, the other end of which is connected to a water pump inlet. Multiple spray holes are provided on the cleaning pipe to spray the water onto the conveyor belt. Below the cleaning pipe is a mounting plate parallel to the conveyor belt, with a vertical drive shaft mounted on the mounting plate. One end of the drive shaft is axially connected to the mounting plate, and the other end is fixedly connected to the bottom side of the cleaning pipe. A tapered gear is fixedly fitted onto the drive shaft. A power motor is mounted on the mounting plate, and the power output end of the motor meshes with the tapered gear to drive the drive shaft to rotate. The spray width of the cleaning pipe and the rotation angle of the drive shaft are negatively correlated; the rotation angle of the drive shaft increases as the width of the plaster mark covering the conveyor belt decreases. The spray duration of the cleaning pipe increases as the length of the plaster mark covering the conveyor belt increases.

[0008] Furthermore, the nozzles include direct nozzles and angled nozzles, with an included angle of 30° between them; wherein, the direct nozzles and angled nozzles are linearly arranged along their axial directions on the periphery of the cleaning pipe; the axis of the direct nozzles is perpendicular to the conveyor belt, and the axis of the angled nozzles is inclined towards the upstream / downstream direction of the conveyor belt.

[0009] Furthermore, the nozzle is provided with a coaxial nozzle on the nozzle hole, the nozzle including a diffuser nozzle and a jet nozzle; wherein, the diffuser nozzle is screwed to the straight nozzle, and the jet nozzle is screwed to the angled nozzle; the diffuser nozzle has a symmetrical arm on the periphery of the water outlet end, and a diffuser cone is provided in the middle of the arm, the cone end of the diffuser cone is set towards the water outlet port of the diffuser nozzle; the jet nozzle has a through conical cavity, and the cone end of the conical cavity forms the jet outlet of the jet nozzle.

[0010] Furthermore, a diffuser disk is provided at the bottom edge of the diffuser cone; wherein, the diffuser disk includes multiple diffuser fins arranged circumferentially at equal intervals, the free ends of the diffuser fins are inclined towards the jet direction and set on the bottom surface of the diffuser cone, and the front surface of the diffuser fins forms a diffuser surface.

[0011] Furthermore, the bottom of the diffuser cone is rotatably connected to the boom, and multiple diffuser fins are circumferentially and equidistantly arranged at the bottom edge of the diffuser cone; wherein, the free end of the diffuser fin is inclined towards the jet direction and set on the bottom surface of the diffuser cone, and the flow-facing surface of the diffuser fin forms the diffuser surface; the diffuser fins are inclined on the cone surface of the diffuser cone, and the diffuser fins drive the diffuser cone to rotate under the impact of the water flow to form a vortex.

[0012] Furthermore, the power motor is controlled by the PLC controller and can drive the transmission shaft to reciprocate within a 90° range; the water inlet hose has an extension length between the water pump and the cleaning pipe to accommodate the rotation range of the cleaning pipe.

[0013] Furthermore, the drive shaft includes a hollow tube, which is connected to the middle of the cleaning tube. One end of the hollow tube has an inlet connector, which is connected to the outside of the hollow tube through a sealed bearing.

[0014] Furthermore, two cleaning devices are symmetrically arranged across both sides of the conveyor belt, and the cleaning pipes spray water onto the areas they cover.

[0015] Furthermore, a jet pipe is provided between the two cleaning devices, and a cleaning nozzle perpendicular to the conveyor belt is provided on the jet pipe. The cleaning nozzle is arranged along the axial direction of the jet pipe. The jet pipe is used to clean the plaster marks in the central area of ​​the conveyor belt. The jet pipe is fixed to the mounting base plate by a support plate, and one end of the jet pipe is connected to the water inlet hose.

[0016] Furthermore, a water absorption device is disposed below the conveyor belt at a distance from the cleaning device, and is located downstream of the cleaning device. The water absorption device includes a sponge roller for absorbing the cleaning water adhering to the surface of the conveyor belt. A drying device is disposed below the conveyor belt at a distance from the water absorption device, and is located downstream of the water absorption device. The drying device includes an air knife assembly for accelerating the evaporation of residual water stains on the surface of the conveyor belt.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] This invention provides a cleaning device with a variable cleaning range installed below the conveyor belt. This allows the adjusted cleaning range to correspond to the span of the plaster marks attached to the conveyor belt, facilitating concentrated cleaning of the plaster marks on the conveyor belt. This avoids the problem of excessive residual water on the conveyor belt after the cleaning device cleans areas not covered with plaster marks, which would increase the drying pressure in the downstream drying section. It also prevents the protective paper under the plasterboard from being easily damaged due to wetting during the conveyor belt transport, thus reducing the defect rate of plasterboard caused by the damage to the protective paper.

[0032] 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.

[0033] like Figure 1-2 As shown, the present invention provides a self-detection fixed-point cleaning system for gypsum board forming conveyors, comprising:

[0034] The cleaning device 10 is located below the head of the conveyor belt 30, and the cleaning device 10 uses water flow to rinse the surface of the conveyor belt 30.

[0035] A visual inspection device 20 is located upstream of the cleaning device 10 and positioned to the side of the conveyor belt 30 to detect plaster marks attached to the conveyor belt 30. The visual inspection device 20 includes a camera element 21, which collects information on the coverage width and length of the plaster marks attached to the conveyor belt 30 and transmits image signals to the PLC controller for calculation. The running time is calculated based on the fixed distance between the cleaning device 10 and the visual inspection device 20 and the running speed of the conveyor belt 30, so that the cleaning device 10 is started at regular intervals after the visual inspection device 20 detects plaster marks.

[0036] The cleaning device 10 includes a cleaning pipe 11, one end of which is open and connected to a water inlet hose 15, and one end of the water inlet hose 15 is connected to a water pump inlet; the cleaning pipe 11 is provided with a plurality of spray holes 12 that spray towards the conveyor belt 30; a mounting base plate 13 parallel to the conveyor belt 30 is provided below the cleaning pipe 11, and a drive shaft 14 is vertically provided on the mounting base plate 13, one end of the drive shaft 14 is axially connected to the mounting base plate 13, and the other end of the drive shaft 14 is fixedly connected to the bottom side of the cleaning pipe 11; A conical tooth 141 is fixedly sleeved on the drive shaft 14, and a power motor 131 is provided on the mounting base plate 13. The power output end of the power motor 131 meshes with the conical tooth 141 to drive the drive shaft 14 to rotate. The spray width of the cleaning pipe 11 and the rotation angle of the drive shaft 14 are negatively correlated. The rotation angle of the drive shaft 14 increases as the width of the plaster mark coverage on the transmission belt 30 decreases. The spray duration of the cleaning pipe 11 increases as the length of the plaster mark coverage on the transmission belt 30 increases.

[0037] The present invention provides a self-detection fixed-point cleaning system for gypsum board forming conveyor belts. By setting a cleaning device 10 with a variable cleaning range below the conveyor belt 30, the adjusted cleaning range can correspond to the span of the gypsum marks attached to the conveyor belt 30. This helps to achieve concentrated cleaning of the gypsum marks on the conveyor belt 30, avoiding the problem of excessive residual water on the conveyor belt 30 after the cleaning device 10 cleans the areas of the conveyor belt 30 without gypsum marks, which would increase the drying pressure of the downstream drying section. It also prevents the protective paper under the gypsum board from being easily damaged due to being wetted when the gypsum board is conveyed on the conveyor belt 30, and reduces the defect rate of gypsum board caused by the damage of the protective paper.

[0038] In the actual production process of this invention, the visual inspection device 20 is first used to inspect and collect information on the plaster marks on the conveyor belt 30. After measuring the length and width of the plaster marks, the inclination of the cleaning pipe 11 relative to the conveying direction of the conveyor belt 30 is adjusted according to its width. The rotation of the cleaning pipe 11 is accomplished by the transmission between the power motor 131 and the transmission shaft 14, so that the spray coverage area of ​​the cleaning pipe 11 in the direction perpendicular to the conveyor belt 30 can be adaptively expanded or reduced.

[0039] In the above embodiments, in order to enable the plaster marks on the conveyor belt 30 to be cleaned by water flow and water mist from multiple angles, thereby improving the cleaning effect of the cleaning pipe 11 on the conveyor belt 30, such as... Figure 3As shown, the nozzle 12 includes a straight nozzle 121 and an angled nozzle 122, with an included angle of 30° between the straight nozzle 121 and the angled nozzle 122. The straight nozzle 121 and the angled nozzle 122 are linearly arranged along their axial directions on the periphery of the cleaning pipe 11. The axis of the straight nozzle 121 is perpendicular to the conveyor belt 30, and the axis of the angled nozzle 122 is inclined towards the upstream / downstream direction of the conveyor belt 30.

[0040] In this embodiment, the conveyor belt 30 can be sprayed by directly opening direct spray holes 121 and oblique spray holes 122 at different angles on the cleaning pipe 11. Since the direct spray holes 121 and oblique spray holes 122 can clean the upstream and downstream areas of the conveyor belt 30 respectively, the oblique spray of the oblique spray hole 122 can be used to make plaster marks, clumps of plaster and the like detach smoothly along the conveying direction of the conveyor belt 30, thereby improving the cleaning effect of the cleaning device 10 on the conveyor belt 30 and reducing the generation of cleaning dead corners on it.

[0041] In order to further improve the cleaning effect of the cleaning device 10 on the conveyor belt 30 by combining pressurized rinsing and range rinsing, such as... Figure 4-5 As shown, in the preferred embodiment provided by the above embodiments of the present invention, a nozzle 16 coaxially arranged on the nozzle 12 is provided, the nozzle 16 including a diffuser nozzle 161 and a jet nozzle 162; wherein, the diffuser nozzle 161 is screwed onto the straight nozzle 121, and the jet nozzle 162 is screwed onto the oblique nozzle 122; a symmetrical arm 163 is provided on the periphery of the water outlet end of the diffuser nozzle 161, and a diffuser cone 164 is provided in the middle of the arm 123, the cone end of the diffuser cone 164 is set toward the water outlet port of the diffuser nozzle 161; a conical cavity is formed through the interior of the jet nozzle 162, and the cone end of the conical cavity forms the jet outlet of the jet nozzle 162.

[0042] In this embodiment, by setting two types of nozzles 16, the jet in the nozzle 12 can be sprayed out through the diffuser nozzle 161 and the jet nozzle 162 to form a diffuser and a jet, respectively. The diffuser expands the cleaning range of the conveyor belt 30, and the jet increases the rinsing pressure on the conveyor belt 30, so that the plaster marks and clumps of plaster on the conveyor belt 30 can be easily removed, thereby improving the cleanliness of the conveyor belt 30.

[0043] In one embodiment of the present invention, the specific structure of the diffuser nozzle 161 is as follows: Figure 5 As shown, a diffuser disk 165 is provided at the bottom edge of the diffuser cone 164; wherein, the diffuser disk 165 includes a plurality of diffuser fins 166 arranged circumferentially at equal intervals, the free ends of the diffuser fins 166 are inclined towards the jet direction and set on the bottom surface of the diffuser cone 164, and the front surface of the diffuser fins 166 forms a diffuser surface.

[0044] In this embodiment, after the jet is ejected through the diffuser nozzle 161, it is first dispersed circumferentially to the diffuser plate 165 by the diffuser cone 164, and then diverted into a diffused state by the diffuser fins 166. This allows a larger area to be cleaned within a local area of ​​the conveyor belt 30, so that after the gypsum marks are dispersed by the jet impact, the larger area of ​​gypsum marks can be further cleaned by the cleaning effect of the diffuser formed by the diffuser nozzle 161.

[0045] In another embodiment provided by the present invention, the specific structure of the diffuser nozzle 161 is as follows: Figure 6-7 As shown, the bottom of the diffuser cone 164 is rotatably connected to the boom 163, and multiple diffuser fins 166 are circumferentially and equidistantly arranged at the bottom edge of the diffuser cone 164; wherein, the free end of the diffuser fin 166 is inclined to the bottom surface of the diffuser cone 164 in the direction of the jet flow, and the flow-facing surface of the diffuser fin 166 forms a diffuser surface; the diffuser fin 166 is inclined on the cone surface of the diffuser cone 164, and the diffuser fin 166 drives the diffuser cone 164 to rotate under the impact of the water flow to form a vortex.

[0046] In this embodiment, since the diffuser fins 166 are inclined propeller-shaped structures, they can use the impact force generated by the jet to drive the diffuser cone 164 to rotate, thereby causing the diffuser to form a swirling flow after passing through the diffuser fins 166, so as to improve the overall cleaning effect of the cleaning device 10 on the conveyor belt 30.

[0047] In order to limit the rotation range of the cleaning pipe 11 and avoid affecting the water pump's connection and delivery due to excessive rotation of the cleaning pipe 11, in one embodiment of the present invention, the power motor 131 is controlled by a PLC controller and can drive the transmission shaft 14 to reciprocate within a range of 90°; the water inlet hose 15 has an extension length between the water pump and the cleaning pipe 11 to accommodate the rotation range of the cleaning pipe 11.

[0048] To facilitate the supply of water to the cleaning pipe 11 and to ensure that the rotation angle of the cleaning pipe 11 is not restricted, such as... Figure 8 As shown, in the preferred embodiment provided by the above embodiments of the present invention, the transmission shaft 14 includes a hollow tube 144, which is connected to the middle of the cleaning tube 11. One end of the hollow tube 144 is provided with an inlet connector 142, which is connected to the outside of the hollow tube 144 through a sealed bearing 143.

[0049] In order to flexibly adjust the cleaning range of the cleaning device 10 and avoid cleaning dead zones on the conveyor belt 30, such as Figure 9-10 As shown, in the preferred embodiment provided by the present invention based on the above embodiments, two cleaning devices 10 are symmetrically arranged across both sides of the conveyor belt 30, and the cleaning pipes 11 spray water onto the areas they cover respectively.

[0050] Please continue reading. Figure 9-10 As shown, in another embodiment of the present invention based on the above embodiments, more specifically, a jet pipe 17 is provided between the two cleaning devices 10, and a cleaning nozzle 171 perpendicular to the conveyor belt 30 is provided on the jet pipe 17. The cleaning nozzle 171 is arranged along the axial direction of the jet pipe 17, and the jet pipe 17 is used to clean the plaster marks in the central area of ​​the conveyor belt 30. The jet pipe 17 is fixed to the mounting base plate 13 by a support plate 172, and one end of the jet pipe 17 is open and connected to the water inlet hose 15.

[0051] In this embodiment, by setting at least two cleaning pipes 11 and simultaneously using a jet straight pipe 17 to supplement the cleaning of the area between the two cleaning pipes 11, the generation of cleaning dead corners can be avoided, and the cleanliness of the conveyor belt 30 can be improved.

[0053] A water-absorbing device 40 is disposed below the conveyor belt 30 and spaced apart from the cleaning device 10. The water-absorbing device 40 is located downstream of the cleaning device 10.
