[0001] The present application relates to the technical field of grain depot waterproofing processing, in particular to a multi-layer composite forming device for waterproofing coiled material specially used in grain depots. BACKGROUND

[0002] As is known, when a grain depot is waterproofed, the warehouse and finished grain warehouse roof waterproofing is relatively high, and the overall principle is to combine rigidity and flexibility, seal the nodes, and efficiently drain water. The roof is mostly selected to use modified asphalt coiled material or high polymer coiled material, and an additional layer is added at the nodes of slope, gutter, eaves, and out-of-roof pipelines. The outer wall uses polymer cement waterproofing mortar in combination with water dispersion and open ditch drainage, the inner wall is provided with a vertical moisture-proof layer below the grain stacking line, and the wall-ground intersection is made high waterproofing return edges. The floor is provided with waterproofing concrete or coiled material moisture-proof layer according to the underground water level.

[0003] The existing technology has the problem that the quality of the waterproofing coiled material laid at the roof, roof, and floor positions as the key waterproofing positions directly affects the waterproofing performance of the grain depot, and the existing technology is mostly to realize the compounding of the waterproofing coiled material by using the gluing and hot melting method in the processing factory. Although it can be quickly taken, it is difficult to increase or reduce the coiled material surface layer according to the actual operation situation, and it is also difficult to customize according to the actual operation laying length. Based on the above-mentioned situation, it is found that the existing grain depot waterproofing coiled material is difficult to avoid the above problems at the same time, and therefore, the present application provides a multi-layer composite forming device for waterproofing coiled material specially used in grain depots, which can adjust the coiled material compounding content as needed, directly drag or use a carrier to pull at the construction grain depot site, and directly composite and fix the composite waterproofing coiled material at the use grain depot position. SUMMARY

[0005] (II) Technical scheme The above technical purpose of the present application is realized by the following technical scheme: a multi-layer composite forming device for waterproofing coiled material specially used in grain depots, comprising a frame, an inner side of the top of the frame is fixedly connected with a horizontal rod, an outer side of the horizontal rod is rotatably connected with a rotating sleeve, a top of the rotating sleeve is fixedly connected with a pressing frame, a material shaft is arranged between the pressing frame and the frame, an inner side of the frame is fixedly connected with a counterweight frame, a bottom of the frame is provided with a roller, and a bottom of the right side of the frame is fixedly connected with a laying assembly. The paving assembly comprises a limiting frame, the bottom of the right side of the limiting frame is fixedly connected with a primary combining frame, the top of the primary combining frame is fixedly connected with a suspension frame, the right side of the suspension frame is rotatably connected with an electric cylinder, the front side and the right side of the right side of the suspension frame are fixedly connected with inclined struts, a rotating rod is fixedly connected between the two inclined struts, the outer side of the rotating rod is rotatably connected with a short frame, the bottom of the short frame is fixedly connected with a hot melting frame, the top of the hot melting frame is fixedly connected with a lifting frame, and the telescopic end of the electric cylinder is rotatably connected with the top of the lifting frame. The hot melting frame comprises a bottom frame, the bottom of the bottom frame is fixedly connected with a quartz glass sheet, the top of the bottom frame is fixedly connected with a condenser cover, and the inner side of the condenser cover is fixedly connected with an infrared lamp tube.

[0006] By adopting the above technical scheme, the required waterproof material roll for composite paving is sleeved on the material shaft outside as needed before use, the cross rod cooperates with the rotating sleeve to connect the table frame and the pressing frame, after the material shaft is placed between the table frame and the pressing frame, the rotating sleeve can be rotated along the cross rod to make the pressing frame press on the top of the table frame to fix the material shaft, then the material roll is sequentially pulled from the bottom and passes through the limiting frame and the primary combining frame of the paving assembly to be preliminarily pressed, then the electric cylinder on the right side of the suspension frame is elongated to push the lifting frame, the hot melting frame connected with the lifting frame falls along the inclined struts through the short frame, and the bottom frame of the hot melting frame is pressed on the surface of the preliminarily pressed material, the infrared light generated by the infrared lamp tube on the inner side of the condenser cover is concentrated downward to heat and melt the composite waterproof material through infrared rays, the heating area is limited in the pressing area to effectively prevent the material roll from bubbling and deviating due to heating, and the hot melting material is directly adhered to the surface of the construction position of the grain depot to achieve one-time forming, and the effect of moving while constructing is achieved.

[0007] The application is further provided that the inner side of the suspension frame is movably connected with a shaft frame, and the inner side of the shaft frame is rotatably connected with a primary pressing shaft.

[0008] By adopting the above technical scheme, the shaft frame is provided to connect the primary pressing shaft, when the material passes through the primary combining frame, the shaft frame and the primary pressing shaft apply pressure to the material downward, and the multiple layers of material are kept relatively flat during paving when moving and pulling.

[0009] The application is further provided that the top of the inner side of the suspension frame is fixedly connected with two connecting barrels, the inner side of the connecting barrel is fixedly connected with a layer barrel, the top and the bottom of the layer barrel are both provided with through holes, the inner side of the connecting barrel is filled with viscous oil, the inner side of the layer barrel is fixedly connected with a rubber plug, the inner side of the rubber plug is fixedly connected with a cylindrical frame, the top and the bottom of the connecting barrel are both slidably connected with the cylindrical frame through sealing members, and the bottom of the cylindrical frame is fixedly connected with the shaft frame.

[0010] By adopting the above technical solution, a connecting cylinder is set up to cooperate with the layer cylinder. The cylindrical frame presses down against the shaft frame to apply downward pressure to the initial pressure shaft. When the construction surface is uneven, causing bumps, or when the travel speed is too fast, causing a large pulling force on the material, the initial pressure shaft, shaft frame, and cylindrical frame are all subjected to the force of the taut material and move upward. During this process, the rubber plug located on the outside of the cylindrical frame pushes the viscous oil along the through hole from the top to the bottom of the layer cylinder, which has a damping effect to slow down the upward movement speed of the shaft frame. This allows the shaft frame to maintain the downward pressure state for a short time, and to move upward when subjected to continuous force. This can prevent the material from being pulled apart due to excessive instantaneous force.

[0011] The invention is further configured such that: the top of the cylindrical frame passes through the suspension frame and is slidably connected to the suspension frame; the top of the suspension frame is fixedly connected to a docking frame by a tension spring; and the tops of both cylindrical frames are fixedly connected to the bottom of the docking frame.

[0012] By adopting the above technical solution, a tension spring is set to continuously pull down the docking frame, so that the docking frame and the cylindrical frame connected to it always maintain downward pressure, which serves as the pressure provided to the shaft frame.

[0013] The present invention is further configured such that: a partition is fixedly connected to the inner side of the limiting frame, and a contact wheel is provided on the left side of the partition; the front and rear sides of the contact wheel are rotatably connected to the inner side of the limiting frame.

[0014] The above technical solution uses a partition plate in conjunction with a contact wheel to limit and guide multiple material rolls before pressing.

[0015] The present invention is further configured such that: two limiting rollers are rotatably connected to the inner side of the platform frame; a torsion spring is fixedly connected between the crossbar and the rotating sleeve; and a bearing seat is fixedly connected to the bottom of the pressure frame and the top of the platform frame, with the inner side of the bearing seat rotatably connected to the material shaft.

[0016] By adopting the above technical solution, by setting limit rollers, when the material is unwound on the outside of the material shaft, it passes between two limit rollers to initially limit the material. The narrow space between the two limit rollers restricts the material from bending or tilting. The set shaft seat is used to fix the position of the material shaft and allows the material shaft to rotate along the inner side of the shaft seat.

[0017] The present invention is further configured such that: a pull frame is movably connected to the left side of the pressure frame via a tension spring; the outer side of the pull frame passes through the pressure frame and is inserted into the platform frame; and a traction frame is fixedly connected to the top and left side of the platform frame.

[0018] Using the above technical solution, by setting up a pull frame, when the pressure frame needs to be pressed down and closed with the platform frame, the pull frame can be pulled to the left first. At this time, the tension spring is stretched and stored. After the pressure frame and the platform frame are fully closed and in contact, the pull frame is inserted into the platform frame through the spring to complete the fixation. When unlocking and changing the roll, the pull frame can be pulled outward. The torsion spring between the rotating sleeve and the crossbar rebounds to drive the structure to reset and unfold. The set traction frame can facilitate personnel to push and pull or connect the vehicle to move.

[0019] The present invention is further configured such that: a rubber tube is provided on the inner side of the frame, and an integrally formed arc-shaped opening is provided on the front and rear sides of the bottom of the rubber tube; an inner wheel is provided on the inner side of the arc-shaped opening; a contact block is provided on the top of the inner wheel; and a reset rod is fixedly connected to the top of the contact block.

[0020] Using the above technical solution, adhesive can be stored as needed by setting up a glue tube. The adhesive will flow to the arc-shaped opening at the bottom. At this time, the bottom of the arc-shaped opening is blocked by the inner wheel, so the adhesive will not be exposed. When the entire glue tube falls, the bottom of the inner wheel contacts the ground and moves upward. At this time, a gap is created between the inner wheel and the arc-shaped opening, allowing the adhesive to flow out and fall on the hot-melt path of the hot-melt frame. During continuous operation, the composite waterproof membrane is bonded to the grain depot construction position by the adhesive, and a stable fixation is formed through high-temperature drying, further improving the fixation strength between the waterproof membrane and the waterproof position of the grain depot.

[0021] The invention is further configured such that: a manual lever is installed on the top of the rubber tube via a tension spring, and the tops of the two reset levers both penetrate the top of the rubber tube and are fixedly connected to the bottom of the manual lever.

[0022] Using the above technical solution, by setting a tension spring to continuously pull down the manual lever, the reset rod connected to the manual lever applies downward pressure to the inner wheel through the contact block.

[0023] The present invention is further configured such that: a screw is rotatably connected to the top of the counterweight frame, a limiting rod is fixedly connected to the top of the counterweight frame, an adjusting frame is threadedly connected to the outer side of the screw, the inner side of the adjusting frame is fixedly connected to the rubber cylinder, and the inner side of the adjusting frame is slidably connected to the limiting rod.

[0024] By adopting the above technical solution, a screw and a limiting rod are set up so that when it is necessary to adjust the lifting of the rubber cylinder, the screw can be rotated so that the adjustment frame connected to it can move vertically up and down under the limit of the limiting rod.

[0025] (III) Beneficial Effects Compared with the prior art, the present invention provides a multi-layer composite molding device for waterproof membranes specifically for grain depots, which has the following beneficial effects: This multi-layer composite molding device for waterproof membranes specifically designed for grain depots uses a material shaft. Before use, the required waterproof membrane rolls are fitted onto the material shaft as needed. A crossbar, in conjunction with a rotating sleeve, connects the platform frame and the pressure frame. After the material shaft is placed between the platform frame and the pressure frame, the rotating sleeve can be rotated along the crossbar to press the pressure frame against the top of the platform frame, thus securing the material shaft. Subsequently, the material rolls are pulled sequentially from the bottom, passing through the limiting frame and the initial closing frame of the covering assembly for initial pressing. Then, the electric cylinder on the right side of the suspension frame extends to push and lift the frame. The hot-melt frame connected to it is lowered by rotating along the diagonal brace via a short frame, and the bottom frame of the hot-melt frame is pressed onto the surface of the initially pressed material. The infrared light generated by the infrared lamp tube located inside the light-concentrating cover is concentrated downward to heat-melt the composite waterproof material through infrared rays. Pressing, heating, melting and shaping are carried out simultaneously. Confining the heating area within the pressing area can effectively prevent the roll material from bubbling or shifting due to heat. It also allows the hot-melt material to be directly adhered to the surface of the grain depot construction site to achieve one-time molding and construction while moving. Attached Figure Description

[0028] 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.

[0029] Example 1 Please see Figures 1-9 A multi-layer composite molding device for waterproof membrane for grain depots includes a frame 1, a crossbar 2 fixedly connected to the inner side of the top of the frame 1, a rotating sleeve 3 rotatably connected to the outer side of the crossbar 2, a pressure frame 4 fixedly connected to the top of the rotating sleeve 3, a material shaft 5 provided between the pressure frame 4 and the frame 1, a counterweight frame 6 fixedly connected to the inner side of the frame 1, a roller 7 installed at the bottom of the frame 1, and a covering component 8 fixedly connected to the bottom right side of the frame 1. The covering component 8 includes a limiting frame 81, a preliminary frame 82 fixedly connected to the bottom right side of the limiting frame 81, a suspension frame 83 fixedly connected to the top of the preliminary frame 82, an electric cylinder 84 rotatably connected to the right side of the suspension frame 83, diagonal braces 85 fixedly connected to the front and right sides of the right side of the suspension frame 83, a rotating rod 86 fixedly connected between the two diagonal braces 85, a short frame 89 rotatably connected to the outside of the rotating rod 86, a hot melt frame 87 fixedly connected to the bottom of the short frame 89, a lifting frame 88 fixedly connected to the top of the hot melt frame 87, and the telescopic end of the electric cylinder 84 rotatably connected to the top of the lifting frame 88. The hot-melt frame 87 includes a bottom frame 871, a quartz glass sheet 872 is fixedly connected to the bottom of the bottom frame 871, a light-concentrating cover 873 is fixedly connected to the top of the bottom frame 871, and an infrared lamp tube 874 is fixedly connected to the inner side of the light-concentrating cover 873. By setting the material shaft 5, the required waterproof material roll for composite laying is placed on the outside of the material shaft 5 before use. The crossbar 2, in conjunction with the rotating sleeve 3, connects the platform frame 1 and the pressure frame 4. After the material shaft 5 is placed between the platform frame 1 and the pressure frame 4, the rotating sleeve 3 can be rotated along the crossbar 2 to press the pressure frame 4 against the top of the platform frame 1 to fix the material shaft 5. Then, the material roll is pulled from the bottom in sequence and passes through the limiting frame 81 and the initial closing frame 82 of the laying component 8 for initial pressing. Subsequently, the electric cylinder 84 on the right side of the suspension frame 83 extends to push the lifting frame 88, so that it is connected to the lifting frame 88. The hot-melt frame 87 is rotated and lowered along the diagonal brace 85 via the short frame 89, and the bottom frame 871 of the hot-melt frame 87 is pressed onto the surface of the initially pressed material. The infrared light generated by the infrared lamp tube 874 located inside the light-concentrating cover 873 is concentrated downward to heat the composite waterproof material through infrared rays. The process of pressing, heating, melting and shaping at the same time effectively prevents the heating area from bubbling or shifting due to heat, and allows the hot-melt material to be directly adhered to the surface of the grain depot construction site to achieve one-time molding and construction while moving.

[0030] The inner side of the suspension frame 83 is movably connected to a shaft bracket 9, and the inner side of the shaft bracket 9 is rotatably connected to a primary pressure shaft 10. By setting the shaft bracket 9 to connect the primary pressure shaft 10, when the material passes through the initial frame 82, the shaft bracket 9 and the primary pressure shaft 10 apply downward pressure to the material. During construction, while moving and pulling, this ensures that the multi-layer material remains relatively flat during laying. Two connecting cylinders 11 are fixedly connected to the top of the inner side of the suspension frame 83. Layer cylinders 12 are fixedly connected to the inner side of the connecting cylinders 11. Through holes are opened at the top and bottom of the layer cylinders 12. The inner side of the connecting cylinders 11 is filled with viscous oil. A rubber stopper 13 is fixedly connected to the inner side of the layer cylinder 12. A cylindrical frame 14 is fixedly connected to the inner side of the rubber stopper 13. The top and bottom of the connecting cylinders 11 are connected to... The cylindrical frame 14 is slidably connected, and its bottom is fixedly connected to the shaft frame 9. A connecting cylinder 11 is installed to cooperate with the layer cylinder 12. The cylindrical frame 14 presses downward against the shaft frame 9 to apply downward pressure to the initial pressure shaft 10. When the construction surface is uneven, causing bumps, or when the travel speed is too fast, resulting in excessive material tension, the initial pressure shaft 10, shaft frame 9, and cylindrical frame 14 are all subjected to the force of the taut material, causing them to move upward. During this process, the rubber plug 13 located on the outside of the cylindrical frame 14 pushes viscous oil along the through-hole from the top to the bottom of the layer cylinder 12, providing a damping effect to slow the upward movement of the shaft frame 9. This allows the shaft frame 9 to maintain downward pressure for a short time, and to continue moving upward under sustained force, preventing excessive instantaneous force on the material. In the event of a breakage, the top of the cylindrical frame 14 passes through the suspension frame 83 and is slidably connected to the suspension frame 83. The top of the suspension frame 83 is fixedly connected to the docking frame 15 via a tension spring. The tops of both cylindrical frames 14 are fixedly connected to the bottom of the docking frame 15. By setting the tension spring to constantly pull down the docking frame 15, the docking frame 15 and the cylindrical frames 14 connected to it always maintain downward pressure, which serves as the pressure provided to the shaft frame 9. A partition 16 is fixedly connected to the inner side of the limiting frame 81. A contact wheel 17 is provided on the left side of the partition 16. The front and rear sides of the contact wheel 17 are rotatably connected to the inner side of the limiting frame 81. By setting the partition 16 in conjunction with the contact wheel 17, it is used to limit and guide multiple material rolls before pressing. Two limiting wheels are rotatably connected to the inner side of the platform frame 1. A torsion spring is fixedly connected between the positioning roller 18, the crossbar 2, and the rotating sleeve 3. A bearing seat 19 is fixedly connected to the bottom of the pressure frame 4 and the top of the platform frame 1. The inner side of the bearing seat 19 is rotatably connected to the material shaft 5. By setting the limiting roller 18, when the material is unwound outside the material shaft 5, it passes between the two limiting rollers 18 to initially limit the material's movement. The narrow space between the two limiting rollers 18 also prevents the material from bending or tilting. The bearing seat 19 is used to fix the position of the material shaft 5 and allows the material shaft 5 to rotate along the inner side of the bearing seat 19. A tension frame 20 is movably connected to the left side of the pressure frame 4 via a tension spring. The outer side of the tension frame 20 passes through the pressure frame 4 and is inserted into the platform frame 1. A traction frame 21 is fixedly connected to the top and left side of the platform frame 1. By setting the tension frame 20…When the pressure frame 4 needs to be pressed down and closed with the platform frame 1, the pull bracket 20 can be pulled to the left first. At this time, the tension spring is stretched and stored. After the pressure frame 4 and the platform frame 1 are fully closed and in contact, the spring rebound causes the pull bracket 20 to pass through the pressure frame 4 and insert into the platform frame 1 to complete the fixation. When unlocking and changing the roll, the pull bracket 20 can be pulled outward. The torsion spring between the rotating sleeve 3 and the crossbar 2 rebounds to drive the structure to reset and unfold. The traction frame 21 is provided to facilitate pushing and pulling by personnel or moving the connecting vehicle.

[0031] The working principle of this embodiment is as follows: First, the multi-layer waterproof membrane rolls are installed on the material shafts 5 between the pressure frame 4 and the platform frame 1. The pressure frame 4 and the pull frame 20 are quickly locked and fixed. The device is dragged and moved by the traction frame 21. After being guided layer by layer by the limiting roller 18, the inner partition 16 of the limiting frame 81, and the contact wheel 17, the membrane enters the initial closing frame 82. It is pre-pressed and flattened by the initial pressure shaft 10. The initial pressure shaft 10 forms a damped floating pressing structure through the connecting cylinder 11, the layer cylinder 12, the viscous oil, the rubber plug 13, and the cylindrical frame 14. The tension spring provides... Under continuous downward pressure, when the roll material experiences sudden changes in force or the ground is uneven, the viscous oil damping can buffer the impact force, preventing the roll material from being torn or wrinkled. After the roll material is initially pressed together, the electric cylinder 84 drives the hot melt frame 87 to swing down, so that the bottom frame 871 presses onto the surface of the roll material. The infrared lamp tube 874 is focused by the light-concentrating cover 873 and the light is transmitted through the quartz glass plate 872, so as to perform directional infrared hot melting on the pressing area, realizing simultaneous movement, pressing, heating and melting and shaping. The multi-layer waterproof roll material is directly composited and laid out on the grain depot construction site.

[0032] Example 2 refer to Figures 1-4 A multi-layer composite molding device for waterproof membrane for grain depots also includes a glue cylinder 22. The glue cylinder 22 is located inside the frame 1. The bottom of the glue cylinder 22 has an integrally formed arc-shaped opening 23 on the front and rear sides. The inner side of the arc-shaped opening 23 is provided with an inner wheel 24. The top of the inner wheel 24 is provided with a contact block 25. The top of the contact block 25 is fixedly connected with a reset rod 26. By setting the glue cylinder 22, adhesive can be stored as needed. The adhesive will flow to the arc-shaped opening 23 at the bottom. At this time, the bottom of the arc-shaped opening 23 is blocked by the inner wheel 24, so the adhesive will not be exposed. When the entire glue cylinder 22 falls, the bottom of the inner wheel 24 contacts the ground and moves upward. At this time, a gap is generated between the inner wheel 24 and the arc-shaped opening 23 for the adhesive to flow out and fall on the hot melt path of the hot melt frame 87. During continuous operation, the composite waterproof membrane is bonded to the construction position of the grain depot by the adhesive, and a stable fixation is formed by high temperature drying, which further improves the fixation strength between the waterproof membrane and the waterproof position of the grain depot.

[0033] The top of the rubber cylinder 22 is fitted with a manual lever 27 via a tension spring. The tops of the two reset levers 26 penetrate the top of the rubber cylinder 22 and are fixedly connected to the bottom of the manual lever 27. By continuously pulling down the manual lever 27 via the tension spring, the reset lever 26 connected to the manual lever 27 applies downward pressure to the inner wheel 24 through the contact block 25. The top of the counterweight frame 6 is rotatably connected to a screw 28, and the top of the counterweight frame 6 is fixedly connected to a limit rod 29. The outer side of the screw 28 is threadedly connected to an adjusting frame 30, the inner side of the adjusting frame 30 is fixedly connected to the rubber cylinder 22, and the inner side of the adjusting frame 30 is slidably connected to the limit rod 29. By setting the screw 28 in conjunction with the limit rod 29, when it is necessary to adjust the lifting and lowering of the rubber cylinder 22, the screw 28 can be rotated, so that the adjusting frame 30 connected to it can move vertically up and down under the limit of the limit rod 29.

[0034] The working principle of this embodiment is as follows: The glue cylinder 22 is used to store the adhesive. Its bottom arc-shaped opening 23 is blocked by the inner wheel 24 to prevent adhesive leakage. Pulling down the manual lever 27 with a tension spring applies continuous downward pressure to the inner wheel 24 through the reset lever 26 and the contact block 25 to maintain the blocked state. During operation, rotating the screw 28 on the counterweight frame 6 causes the adjusting frame 30, which is threadedly connected to the screw 28, to drive the glue cylinder 22 to rise and fall vertically under the limiting action of the limiting lever 29. When the glue cylinder 22 descends to the point where the inner wheel 24 contacts the ground, the inner wheel 24 moves upward under the reaction force of the ground, forming a gap with the arc-shaped opening 23. The adhesive flows out along the gap to the hot melt path of the hot melt frame 87. The high temperature of the hot melt dries the adhesive, strengthening the fixing strength between the composite waterproof membrane and the grain depot construction surface.
