Description

Technical Field

[0001] The invention relates to the technical field of coiled material edge pressing devices, in particular to an edge pressing device for producing waterproof coiled materials. Background Art

[0002] Waterproofing membrane refers to a waterproofing material product made by impregnating asphalt or polymer waterproofing materials on the base. It is provided in the form of a roll and is called waterproofing membrane. Waterproofing membrane is mainly used in building walls, roofs, tunnels, roads and landfills. It is a kind of flexible building material product that can be rolled into a roll to prevent the leakage of rainwater and groundwater from the outside. As a leak-free connection between the engineering foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project. In the production process of waterproofing membrane, a pressing device is required to flatten the edge of the membrane.

[0003] There are generally two ways of pressing edges in the existing edge pressing devices for waterproofing membrane production. The first is to press edges by rotation through an extrusion roller, and the second is to press edges vertically through a hydraulic press. Both of these extrusion methods make it difficult to press and push the membrane from the middle to the edges on both sides, resulting in the membrane being continuously pushed to the input end for accumulation during the rotation extrusion process, causing changes in the internal structure of the membrane. Some multi-layer membranes will have chaotic stratification during rotation extrusion, while direct linear extrusion will cause the membrane to spread to all sides at the same time. This diffusion is relatively messy and is also prone to internal stratification and mixing, affecting the quality of the waterproofing membrane. To this end, we propose an edge pressing device for waterproofing membrane production. Summary of the invention

The operation of the device is convenient and efficient. It can extrude and trim the waterproof membranes of different thicknesses and widths. At the same time, it adopts the extrusion method from the middle to both sides.

The first threaded rod 27 passes through the sliding frame 25 and is threadedly connected to the sliding frame 25. A driving member 28 for driving the cutting knife 7 to rise and fall is provided on the guide block 23.

[0036] The driving member 28 includes a pushing rod 29 fixedly mounted on the upper side of the guide block 23, a second connecting cavity 30 connected to the second liquid storage cavity 13 is opened in the positioning column 9, a control plate 31 is slidably connected in the second connecting cavity 30 along the horizontal direction, a control tube 32 is fixedly connected to the control plate 31, one end of the control tube 32 is connected to the second connecting cavity 30, and the pushing rod 29 is slidably connected to one end of the control tube 32 along the vertical direction.

[0037] The adjustment control unit 22 includes a hydraulic pipe 33 fixedly mounted on the fixed frame 2, a hydraulic block 34 is slidably connected inside the hydraulic pipe 33, an electric telescopic rod 35 is fixedly connected to the fixed frame 2, the telescopic end of the electric telescopic rod 35 is fixedly connected to one side of the hydraulic block 34, one end of the hydraulic pipe 33 is connected to the third pipe 36, and the first pipe 17 is slidably connected to the inner wall of the third pipe 36 along the vertical direction.

[0038] The adjusting member 16 includes a lifting block 37 fixedly installed on both sides of the positioning column 9, a first roller 38 is rotatably connected between the two groups of lifting blocks 37, a second roller 39 is rotatably connected to the body 1, a driving shaft 40 is rotatably connected to the body 1, two groups of first bevel gears 41 are coaxially fixedly connected to the driving shaft 40, two groups of second threaded rods 42 are rotatably connected to the fixing frame 2, the two groups of second threaded rods 42 respectively penetrate the lifting blocks 37 on both sides, and are threadedly connected to the lifting blocks 37, and the bottom end of the second threaded rod 42 is coaxially fixedly connected to the second bevel gear 43 meshing with the first bevel gear 41.

[0039] In the present embodiment, one end of the waterproofing membrane 52 is wound by the winding shaft 3, and the waterproofing membrane 52 slides on the upper surface of the machine body 1. The first bevel gear 41 is driven by rotating the driving shaft 40 to rotate the second bevel gear 43, and the second bevel gear 43 drives the second threaded rod 42 to rotate. The height of the lifting block 37 and the positioning column 9 is adjusted so that the distance between the bottom surface of the positioning column 9 and the top surface of the machine body 1 is exactly the required thickness of the waterproofing membrane 52. The transportation of the waterproofing membrane 52 is guided by the first roller 38 and the second roller 39, and the gap distance between the first roller 38 and the second roller 39 is exactly the thickness of the waterproofing membrane 52.

[0040] The hydraulic block 34 is pushed to slide in the hydraulic pipe 33 by the electric telescopic rod 35. The hydraulic pipe 33 is used to store hydraulic oil. The hydraulic block 34 squeezes the hydraulic oil into the third pipe 36. The hydraulic oil is input into the first liquid storage chamber 12 through the first pipe 17, pushing the first sliding block 11 and the first extruding block 5 to move downward. At this time, the side of the first sliding block 11 blocks the opening of the first connecting chamber 19, so that the first liquid storage chamber 12 is not connected with the first connecting chamber 19. The bottom of the first extruding block 5 continuously squeezes the middle position of the waterproof coiled material 52, so that the waterproof coiled material 5 2 can only overflow to both sides and the side away from the positioning column 9. When the first extrusion block 5 reaches the bottom, the first sliding block 11 just opens a gap on the upper side of the first connecting cavity 19, so that the hydraulic oil can be input into the first connecting cavity 19 through the gap. At this time, the first spring block 44 just fits into the triangular groove 47 on the first sliding block 11 for limiting. The hydraulic oil in the first connecting cavity 19 is input into the second liquid storage cavity 13 through the second pipe 18, pushing the second sliding block 14 and the second extrusion block 6 to move downward, so as to realize the extrusion of the two sides of the waterproof membrane 52.

[0041] The second extrusion block 6 and the second liquid storage chamber 13 can be provided with multiple groups, so that the extrusion is performed step by step from the middle to both sides, and the continuity of the extrusion process is improved. The first threaded rod 27 is rotated to make the sliding frame 25 slide in the sliding groove 24. The sliding frame 25 drives the guide block 23 and the cutting knife 7 to move and fit the side of the outermost second extrusion block 6. The width of the second extrusion block 6 can be changed according to the required width of the waterproof coiled material 52. After the plug-in hole 49 on the second extrusion block 6 of the appropriate width is plugged and fixed with the plug-in rod 48 The second extrusion block 6 can be fixed by screwing on the nut 50. When the second extrusion block 6 and the second sliding block 14 are moved down to the set position, the second connecting chamber 30 is connected with the second liquid storage chamber 13, and the hydraulic oil is input into the second connecting chamber 30. The hydraulic oil is input through the control tube 32 to push the push rod 29 downward, so that the cutting knife 7 moves downward to synchronously cut the two sides of the waterproof membrane 52. A guide plate is also provided at the bottom of the sliding frame 25 for pushing the cut scraps to both sides and transporting them to the collection box 51 for collection.

[0042] The control panel 31 is arranged so that when the position of the sliding frame 25 is adjusted, one end of the control tube 32 can always be connected with the second connecting chamber 30, and the elastic force of the second spring block 45 is smaller than the elastic force of the first spring block 44, so that when resetting, the electric telescopic rod 35 drives the hydraulic block 34 to suck, and the hydraulic oil in the control tube 32 and the second connecting chamber 30 is firstly sucked out, so that the cutting knife 7 moves up, and then drives the second sliding block 14 to move up, and the second spring block 45 gradually releases the clamping of the triangular groove 47 on the second sliding block 14, At this time, due to the strong clamping force of the first spring clamping block 44, the first sliding block 11 will maintain its original position until the second sliding block 14 moves to the top, the pressure in the first liquid storage chamber 12 continues to decrease, and finally drives the first sliding block 11 to move up, and the first extrusion block 5 completes the reset. After that, the winding shaft 3 is reeled up again for a distance, so that the waterproof membrane 52 that has just been squeezed is transported to the bottom position of the positioning column 9, and the thicker waterproof membrane 52 moves to the bottom of the first extrusion block 5 and the second extrusion block 6 for subsequent extrusion operations.

[0043] The device is convenient and efficient to operate, and can perform extrusion and trimming operations on waterproof membranes 52 of different thicknesses and widths. At the same time, it adopts an extrusion method from the middle to both sides. Each section of the extrusion is relatively independent, and most of the material will be pushed to both sides and cut off. There will be no continuous extrusion to one side, which will cause continuous accumulation of internal materials and continuous increase in material thickness. The stability of the internal material structure is more effectively guaranteed.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
