Description

Technical Field

[0001] The invention relates to the technical field of waterproof coiled material production, and in particular to an automatic deviation-correcting device for an upper coating. Background Art

[0002] Waterproofing roll is a rollable sheet waterproofing material. It is made of base materials such as base paper, fiber fabric, fiber felt, etc., which are dipped in asphalt and sprinkled with powder, granular or sheet materials on the surface.

[0003] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, etc. It is a kind of rollable flexible building material product that protects against external rainwater and groundwater leakage. As a leak-free connection between the project foundation and the building, it is the first guarantee for waterproofing the entire project and plays a vital role in the entire project.

[0004] There is no automatic deviation correction system in the traditional production of waterproof membrane coating. Most of them are manually adjusted by screw structure and manually shaken to correct the deviation. When the base or mask of the membrane deviates, the high temperature adhesive on the surface of the membrane will stick to the surface of the drum, which will cause the machine to stop. Only human beings are watching. When the membrane deviates, the personnel turn the hand wheel to drive the screw to correct the deviation. This deviation correction is inefficient and requires special personnel to supervise, which increases labor and production costs. For example, the patent with announcement number CN210911592U has a deviation correction mechanism for waterproof membrane coating, which requires manual shaking of two screws to achieve deviation correction. Summary of the invention

[0005] The object of the present invention is to provide an automatic deviation-correcting device for an upper coating film in order to solve the above-mentioned problems in the prior art.

[0012] Furthermore, a Z-shaped rod is vertically connected to the middle of the rectangular surface of the arch block, the regular prism is a hollow structure, and the side wall of the regular prism is provided with a through hole for the Z-shaped rod to pass through and rotate.

[0013] Furthermore, a movable cylinder is axially slidably arranged in the regular prism, and a side wall of the movable cylinder is provided with strip holes corresponding to the Z-shaped rods one by one, and the strip holes extend along the circumferential direction of the movable cylinder; the inner end of the Z-shaped rod extends into the strip hole.

[0015] Furthermore, a photoelectric sensor is provided on the upper side of the floating box, and the photoelectric sensor corresponds to the outer side of the edge of the coil base; when the photoelectric sensor cannot detect the coil base, the arched surface of the arch block is parallel to the moving direction of the coil base; when the photoelectric sensor detects the coil base, the arched block rotates synchronously in the same direction.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention supports the coil base through the buoyancy box and the rollers on its upper side. The buoyancy box floats on the water surface with small lateral movement resistance, and the lateral movement resistance of the buoyancy box is smaller than the relative lateral movement resistance between the coil base and the rollers, so that the buoyancy box and the film rollers on its upper side can follow the lateral movement of the coil base and accurately coat the coil base with film.

For example, the object "provided with" may be a part of the body, or may be arranged separately from the body and connected to the body, and the connection may be a detachable connection or an inseparable connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Specific embodiments of the automatic deviation-correcting device for the upper coating provided by the present invention: See also Figure 1-11 The automatic deviation-correcting device for the upper film coating comprises a box frame 1, a floating box 2, a plurality of rollers, a film roller 6 for supporting the film roll, and a pressure roller group 7.

[0033] The box-type frame 1 has an opening on the upper side and has water inside. The water surface is located in the middle of the box-type frame 1. A tubular overflow port 3 is provided on one side of the middle of the box-type frame 1. When the water surface is higher than the overflow port 3, excess water will be discharged from the overflow port 3. A threaded joint is provided on the outer side of the end of the overflow port 3 for connecting with an external water pipe and a water tank.

[0034] During the film coating process on the waterproof coiled material, since the temperature of the asphalt glue on the surface of the coiled material base 16 is relatively high, after the upper side is coated, the film is covered with the asphalt glue and the surface of the film needs to be cooled immediately, generally by spraying with a water pipe for cooling; the correction device implemented in this embodiment can be equipped with a water cooling device, such as installing a water pump to pump the water in the water tank out to the spray water pipe, and the spray water pipe sprays water to the surface of the waterproof coiled material film after coating to cool it down, and the water falls into the box-type frame 1, and the excess water is discharged from the overflow port 3 to keep the water level in the box-type frame 1 stable, and the water discharged from the overflow port 3 flows back to the water tank to realize circulation.

[0035] The pontoon 2 floats on the water surface in the box frame 1; the lower part of the pontoon 2 is immersed in the water surface, and the lower part of the pontoon 2 discharges water to provide stable buoyancy; there needs to be a gap between the lateral sides of the pontoon 2 and the box frame 1; in this embodiment, there is a gap between the four sides of the pontoon 2 and the inner side of the box frame 1. A roller frame 8 is provided on the upper side of the pontoon 2 to support the rotation of each roller.

[0036] Several rollers are installed on the upper side of the pontoon 2 in parallel and supported on the lower side of the coil base 16. The coil base 16 passes through the upper side of the pontoon 2 along the upper side of each roller. The rollers actively rotate to drive the coil base 16 to move or passively rotate under the movement of the coil base 16.

[0037] The outer sides of both ends of the box frame 1 are provided with brackets 13, and a plurality of smooth guide rollers 14 are provided on the upper sides of the brackets 13; the guide rollers 14 on the upper sides of the brackets 13 gradually decrease in height as they move away from the box frame 1. The upper support height of the highest guide roller 14 is not higher than the upper support height of the idler roller, so that the idler roller can hold up the coil base 16 at a higher position, ensuring that the coil base 16 exerts a certain downward pressure on the idler roller, thereby ensuring that the idler roller has a certain lateral friction resistance to the coil base 16 when the coil base 16 moves laterally.

[0038] The smooth guide roller 14 has a smooth outer surface, and while rolling and supporting the coil base 16 to move, the lateral friction force on the coil base 16 is small.

[0039] In this embodiment, the rollers include a plurality of smooth rollers 4 and a plurality of anti-deflection rollers 5 with protrusions on the surface. The smooth rollers 4 and the anti-deflection rollers 5 are at the same height; the smooth rollers 4 have a smooth surface and have a small lateral friction force on the coil base 16, and their main function is to roll and support the coil base 16 for conveying and moving; therefore, the smooth rollers 4 passively rotate during the conveying and moving process of the coil base 16.

[0040] The protrusions on the outside of the anti-skew roller 5 are preferably circumferential ring-shaped protrusions, which are evenly distributed along the axial direction of the anti-skew roller 5. If the anti-skew roller 5 with such protrusions has a tendency to shift laterally, the friction resistance between the anti-skew roller 5 and the coil base 16 is large. The protrusions can be made of high-temperature resistant rubber material, or high-temperature resistant metal material with a rough surface, to increase the friction coefficient with the coil base 16 and reduce the lateral shift between the coil base 16 and the anti-skew roller 5.

[0041] The temperature of the coil base 16 is relatively high and its surface has high-temperature sticky asphalt glue, so it is difficult to limit it effectively and without pollution; because the friction coefficient between the guide roller 14 and the coil base 16 is relatively small, the coil base 16 is easy to deviate laterally; the resistance between the pontoon 2 and the water is relatively small, and the water's resistance to the lateral displacement of the pontoon 2 is relatively small, making the pontoon 2 easy to deviate laterally; when the coil base 16 undergoes a certain degree of left and right lateral displacement during the conveying movement of the production line, due to the large friction coefficient and friction resistance between the coil base 16 and the anti-deflection roller 5, it is difficult for them to move relative to each other laterally; the lateral displacement of the coil base 16 can drive the anti-deflection roller 5 and the pontoon 2 to move laterally on the water surface.

[0042] The film roller 6 supporting the facial mask roll is rotatably mounted on the upper side of the buoyancy box 2, and its height is higher than the idler roller; the roll base 16 passes through the pressure roller group 7, and the facial mask passes through the pressure roller group 7 and adheres to the upper side of the roll base 16. In this embodiment, the pressure roller group 7 includes two layers of three rollers, the two rollers in the lower layer are at the same height as the idler rollers, and the one roller in the upper layer is located on the upper side between the two rollers in the lower layer, and the lowest point of the one roller in the upper layer is lower than the highest point of the two rollers in the lower layer.

[0043] When the coil base 16 is offset during the conveying movement of the production line, the pontoon 2 will be driven to move horizontally on the water surface first; the horizontal movement of the pontoon 2 drives the film roller 6 and the mask roll to move horizontally synchronously through the roller frame 8, so that the mask roll moves horizontally with the coil base 16 at all times; thereby ensuring that the mask always corresponds to the coil base 16 accurately, and can fully cover the asphalt glue on the upper side of the coil base 16, ensuring the accuracy of the film coating. Through the follow-up deviation of the pontoon 2 with small resistance on the water surface, the relative deviation between the mask and the coil base 16 can be avoided, and the film coating correction of the upper film coating process can be achieved, and this process does not require manual intervention; and the correction process does not rely on the use of external power equipment and its actions, and can achieve automatic correction, reducing the cost of installing drive equipment and saving the production cost of operating external power equipment.

[0044] The roller frame 8 on the upper side of the pontoon 2 is provided with motors for driving the idler rollers, the film roller 6 and the pressure roller group 7 to rotate respectively; specifically, in this embodiment, the anti-deviation roller 5 is connected to a motor for driving its rotation; the upper roller in the pressure roller group 7 is connected to a motor for driving its rotation; and the film roller 6 is connected to a motor for driving its rotation. In some other embodiments, when the migration force of the coil base 16 outside the production line is sufficient, the motor setting can be reduced; the anti-deviation roller 5, the pressure roller group 7 and the film roller 6 can all be passively rotated, and there is no need to set a motor for driving them to rotate; or the motor driving one or more of the anti-deviation roller 5, the pressure roller group 7 and the film roller 6 can be selectively removed.

[0045] In order to ensure the stable lateral movement of the pontoon 2, the pontoon 2 is prevented from moving along the conveying direction with the coil base 16. In this embodiment, both ends of the pontoon 2 are vertically slidably connected with a wheel frame 10, and the shape of the wheel frame 10 is an inverted L shape; the vertical section of the wheel frame 10 is slidably connected to the end of the pontoon 2, and the end of the pontoon 2 is provided with a guide tube 12 for the vertical sliding of the wheel frame 10; the cross-section of the vertical section of the wheel frame 10 is rectangular, and the inner side of the guide tube 12 is a rectangle matching the vertical section of the wheel frame 10, so that the wheel frame 10 can only move vertically and cannot rotate horizontally. A horizontally rotating guide wheel 11 is installed on the upper end of the wheel frame 10; a horizontal wheel groove 9 is provided on the inner side of both ends of the box-type frame 1, and the vertical section of the wheel groove 9 is a U-shape with the opening facing the horizontal side; the guide wheel 11 extends into the wheel groove 9 and moves horizontally back and forth along the wheel groove 9. In this way, since the guide wheel 11 rolls laterally along the wheel groove 9, the pontoon 2 cannot move in the conveying direction of the coil base 16 without affecting the lateral movement of the pontoon 2 by adding a small resistance, thereby ensuring the stable lateral movement of the pontoon 2.

[0046] In this embodiment, four groups of wheel frames 10 and guide wheels 11 are provided, and two groups are provided at both ends of the pontoon 2. Two wheel grooves 9 are provided, which are located on the inner sides of both ends of the box frame 1. On the other hand, due to the cooperation of the guide wheels 11 and the wheel grooves 9, the pontoon 2 can be stably moved horizontally to avoid the pontoon 2 from being tilted and swayed due to the fluctuation of the water surface in the box frame 1. In some embodiments, static water can be used to prevent the water in the box frame 1 from circulating; the water surface area can be increased, that is, the volume and cross-section of the box frame 1 are increased to increase the distance between the outer side of the pontoon 2 and the inner side of the box frame 1; and other means can be used to enhance the stability of the water surface, reduce the impact of the movement of the pontoon 2 on the water surface, and improve the stability of the lateral movement of the pontoon 2.

[0047] During the process of laminating, the weight of the mask roll gradually decreases due to the consumption of the mask roll; although the reduced weight is limited relative to the total weight of the floating body on the water surface, it will cause the pontoon 2 to move up slightly; the wheel frame 10 is vertically slidably connected to the pontoon 2, and the slight rise of the pontoon 2 will not interfere with the vertical position of the wheel frame 10 and the guide wheel 11, and will not apply vertical force to the guide wheel 11, ensuring the normal lateral movement of the guide wheel 11 along the wheel groove 9. It will also increase the friction between the anti-deviation roller 5 and the coil base 16, so that the relative positions of the anti-deviation roller 5 and the pontoon 2 and the coil base 16 are more stably consistent, reducing the phenomenon of the pontoon 2 offsetting relative to the coil base 16.

[0048] Most of the lateral deviation problems of the coil base 16 can be solved by driving the film roller 6 with the coil base 16 by the buoyancy box 2. If the coil base 16 is relatively offset from the buoyancy box 2 and the anti-deviation roller 5, deviation correction is also required. Conventional devices that use a lead screw to correct the deviation of the entire material, such as a waterproof roll conveying and correcting device with a patent publication number of CN208790844U, cannot use the rollers in the above-mentioned technology to clamp and correct the deviation because the upper side of the roll base 16 covered with a film in this embodiment is high-temperature molten asphalt glue, and can only be provided with a lead screw-driven transverse translation plate on the lower side of the roll base 16, and the transverse translation plate corrects the deviation of the corresponding part of the roll base 16 on its upper side through friction. Since the roll base 16 is continuously conveyed, the transverse translation plate only performs a single transverse movement. Once the friction force of the transverse translation plate on the lower side of the roll base 16 cannot be used to correct the position of the roll base 16, and the transverse translation plate moves relatively laterally on the lower side of the roll base 16, the correction will fail. Therefore, the above-mentioned technology and its structural deformation cannot be applied to correct the position of the roll base 16.

[0049] In this embodiment, the anti-skew roller 5 includes a right prism 501, which is a regular hexagonal prism. Each rectangular face of the right prism 501 is provided with a row of several bow blocks 502, and the bow blocks 502 can be used as the aforementioned protrusions. The bow blocks 502 on each rectangular face of the right prism 501 correspond axially, and a circle of six bow blocks 502 can form a circular annular protrusion; the length of the rectangular face of the bow block 502 is the same as the width of the rectangular face of the right prism 501. In some other embodiments, the length of the rectangular face of the bow block 502 is slightly smaller than the width of the rectangular face of the right prism 501; the middle part of the rectangular face of the bow block 502 is rotatably connected to the right prism 501, and when the bow block 502 rotates, the rectangular face of the bow block 502 fits with the rectangular face of the right prism 501 where it is located. In some other embodiments, the rectangular face of the bow block 502 is parallel to the rectangular face of the right prism 501 where it is located and there is a small gap.

[0050] A Z-shaped rod 503 is vertically connected to the middle of the rectangular surface of the arch block 502. The Z-shaped rod 503 in this embodiment is a three-section rod-shaped structure with two right-angle bends. The right prism 501 is a hollow structure. The side wall of the right prism 501 is provided with through holes 504 for the Z-shaped rod 503 to pass through and rotate. The number of through holes 504 is the same as that of the Z-shaped rod 503 and they correspond one to one. In order to ensure that the Z-shaped rod 503 can only rotate and will not cause the arch block 502 to move away from the right prism 501, a limit ring 505 is provided on the outside of the Z-shaped rod 503 inside the right prism 501.

[0051] A movable cylinder 506 is axially slidably arranged inside the right prism 501, and side edges 508 are symmetrically arranged on both sides of the movable cylinder 506. A sliding groove 509 is arranged on the inner wall of the right prism 501 to slide with the side edges 508. The side edges 508 extend into the sliding groove 509 and slide along the sliding groove 509, so that the movable cylinder 506 can only slide axially and cannot rotate.

[0052] The side wall of the movable cylinder 506 is provided with strip holes 507 corresponding to the Z-shaped rods 503, and the strip holes 507 extend along the circumferential direction of the movable cylinder 506; the inner end of the Z-shaped rod 503 extends into the strip holes 507. A core frame 510 is provided inside the movable cylinder 506, and an automatic telescopic rod 511 is connected between one end of the core frame 510 and the inner side of the regular prism 501. The automatic telescopic rod 511 is an electric telescopic rod. In some embodiments, a conductive slip ring is provided at the end of the anti-deflection roller 5, and the cable of the automatic telescopic rod 511 passes through the central axis of the anti-deflection roller 5 and is connected to the conductive slip ring, and the power supply and control of the automatic telescopic rod 511 are realized through the conductive slip ring.

[0053] By extending and retracting the telescopic end of the automatic telescopic rod 511, the movable cylinder 506 is moved axially in the regular prism 501. The bidirectional movement of the movable cylinder 506 can make the Z-shaped rod 503 and the bow block 502 rotate in two directions respectively through the strip hole 507. When the coil base 16 is not offset on the anti-skew roller 5, the bow surface of the bow block 502 can be made parallel to the moving direction of the coil base 16. At this time, the bow block 502 will not affect the conveying direction of the coil base 16. When the coil base 16 is offset on the anti-skew roller 5, the bow block 502 can also be rotated to make it tilted with the conveying direction of the coil base 16, such as Figure 6 As shown, the bow blocks 502 are distributed in a spiral shape on the outside of the regular prism 501, and one end of the anti-skew roller 5 is driven by a motor. The anti-skew roller 5 causes the coil base 16 to shift axially or laterally in the opposite direction through the spirally distributed bow blocks 502, thereby achieving deviation correction of the coil base 16 on the anti-skew roller 5. The deviation correction structure can perform deviation correction continuously without the occurrence of deviation correction failure.

[0054] The arc block 502 can rotate in different directions to form a positive spiral and a reverse spiral outside the positive prism 501; thereby, the deviation correction of the coil base 16 to the left outside the anti-deviation roller 5 and the deviation correction of the coil base 16 to the right outside the anti-deviation roller 5 can be achieved.

[0055] In order to realize automatic deviation correction, in this embodiment, two groups of photoelectric sensors 15 are arranged on the upper side of the buoy 2, and the two groups of photoelectric sensors 15 correspond to the outer sides of the two edges of the coil base 16 respectively; when the photoelectric sensors 15 cannot detect the coil base 16, it means that the coil base 16 has not deviated on the anti-deviation roller 5, and the arcuate surface of the arch block 502 is parallel to the moving direction of the coil base 16; when one group of photoelectric sensors 15 detects the coil base 16, it means that the coil base 16 has deviated to one side on the anti-deviation roller 5, and the arch block 502 rotates synchronously in the same direction, and the arch block 502 forms a positive spiral or a reverse spiral outside the positive prism 501, correcting the lateral position of the coil base 16 on the anti-deviation roller 5. In some embodiments, a PLC controller is provided, and the PLC controller controls the automatic telescopic rod 511 to move the movable cylinder 506 in one direction according to the signal detected by the photoelectric sensor 15, thereby causing the arch block 502 to rotate synchronously in the same direction and form a positive spiral or a reverse spiral outside the positive prism 501. After the deviation is corrected, the arch block 502 is reset, that is, reset to Figure 2 state.

[0056] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments without creative work, or replace some of the technical features therein with equivalents.
