Description

Technical Field

[0001] The invention relates to the technical field of waterproof coiled material detection, and in particular to a sampling device for detecting the waterproofness of a waterproof coiled material. Background Art

[0002] The waterproof test of waterproof membrane can ensure that the waterproof membrane can effectively prevent water penetration in practical applications, thereby ensuring the durability and safety of the building. When testing the waterproofness of waterproof membrane, the existing method is to first prepare the sample, usually by cutting a circular sample from the waterproof membrane through a sample cutting device, and then placing the sample in the detection device, and actively increasing the water pressure to detect the waterproof performance of the waterproof membrane under different water pressures. However, the samples currently made by the sample cutting device have an uneven periphery after cutting. This unevenness can easily cause water to leak from its periphery during the waterproof test, thereby affecting the accuracy of the test results. In addition, the sample cutting operation is completed manually, which increases the difficulty of cutting when cutting thicker samples. Summary of the invention

[0003] The present invention provides a waterproof coiled material waterproof property detection cutting device to solve the above-mentioned deficiencies in the prior art, solve the problems of greater difficulty in cutting samples and poor effect on the peripheral side after cutting, and has strong practicality.

[0004] In order to achieve the purpose of the present invention, the following technologies are proposed: A waterproof coiled material waterproofness detection and cutting device comprises a base, a support is provided at the upper end of the base, a cutting mechanism is provided at the upper end of the support, a positioning mechanism is provided at the lower end of the cutting mechanism, a suction mechanism is provided on the base, the base comprises a bottom plate, a plurality of supporting legs are installed on the bottom plate, the support is used to support the waterproof coiled material, the cutting mechanism is placed on the support, and the waterproof coiled material positioned by the positioning mechanism is cut into a circular structure, the suction mechanism is used to suck the lower side of the waterproof coiled material to position the waterproof coiled material, and when the cutting is completed, the waterproof coiled material located in the cutting mechanism is pulled out. When cutting, the waterproof coiled material is placed on the support, and then the cutting mechanism is started, and the waterproof coiled material is cut by the cutting mechanism. When cutting, the waterproof coiled material is first sucked and fixed by the suction mechanism, and the waterproof coiled material is positioned by the positioning mechanism before cutting, so as to prevent the waterproof coiled material from moving during cutting, thereby ensuring the quality of cutting. During cutting, the sample is directly shaped by the cutting mechanism, thereby improving the efficiency of sample cutting and preparation and the smoothness of the circumference. At the same time, when the cutting is completed, the suction mechanism can also pull out the cut sample.

[0005] Further, the support member includes a plurality of middle support rods installed on the bottom plate, and a pad is installed on the upper end of the middle support rod, and a circular hole is provided on the pad, and the pad plays a supporting role for the cut sample. A pair of first strip holes and a pair of second strip holes are respectively provided at both ends of the pad, and the second strip hole is located outside the first strip hole. A plurality of vertical rods are installed on the bottom plate, and a gasket is installed on the upper end of the vertical rod, and a middle hole is provided on the gasket, which is located in the circular hole, and there is an annular gap between the inner periphery of the gasket and the outer periphery of the circular hole. When cutting the sample, the outer periphery of the gasket acts as a supporting component for the outer periphery of the sample to ensure the effect of the outer periphery after the sample is cut. Of course, this effect is formed by the joint action of the following ring cutting cover, and the formed annular gap plays a role of avoiding the cutting movement of the ring cutting cover, so that the blade of the ring cutting cover cuts through the waterproof coiled material, thereby facilitating the direct cutting and forming of the sample.

[0006] Furthermore, the cutting mechanism includes a guide rod installed at the upper end of the middle support rod, an upper plate is installed at the upper end of the guide rod, a hydraulic cylinder is installed at the upper end of the upper plate, a lower pressure plate is installed at the movable end of the hydraulic cylinder, the guide rod is inserted through the lower pressure plate, a plurality of lower extension rods are installed on the lower pressure plate, a ring cutting cover is installed at the lower end of the lower extension rod, the outer peripheral lower end of the ring cutting cover is a blade-shaped structure, the ring cutting cover is inserted in the annular gap, a pair of T-shaped grooves are respectively provided at both ends of the lower pressure plate, and a third strip hole is provided at the upper end of the T-shaped groove. During cutting, the ring cutting cover moves toward the waterproof coil placed on the gasket ring and the gasket under the drive of the hydraulic cylinder, and finally cuts the waterproof coil through the ring cutting cover and obtains a circular sample. First, the hydraulic cylinder is used as the power source during cutting, which is convenient for cutting waterproof coils of different thicknesses, thereby expanding the scope of application. Secondly, the cutting component used is a ring structure, which can ensure the roundness of the sample periphery as much as possible during cutting, and this cutting method can also ensure the smoothness of the sample periphery.

[0007] Furthermore, a plurality of reinforcing ribs are provided at the inner upper end of the ring-cut cover to enhance the compressive strength of the ring-cut cover to prevent deformation.

[0008] Furthermore, the positioning mechanism includes two pairs of movable vertical rods passed through the lower pressure plate, the upper ends of the movable vertical rods are provided with limit heads, and the lower ends of each pair of movable vertical rods are equipped with positioning plates, and the movable vertical rods are provided with a first spring, and the first spring is located between the positioning plate and the lower pressure plate, and the limit head is located above the lower pressure plate. When the lower pressure plate moves downward, the positioning plate moves downward first to act on the upper side of the waterproof membrane through the positioning plate, and stably fix the waterproof membrane between the pad and the positioning plate. In this way, the waterproof membrane can be prevented from moving inward due to the downward force of the ring cutting cover during cutting. At the same time, the waterproof membrane can be kept in a tensioned state during cutting, thereby facilitating the cutting operation and ensuring the effect after cutting and the efficiency of cutting.

[0009] Furthermore, the positioning plate is in an L-shaped structure. Through the design of the L-shaped structure, the side wall of the waterproof membrane can be limited by the vertical section of the positioning plate, thereby further ensuring the cutting effect.

[0010] Furthermore, the suction mechanism includes a movable disk sleeved on the vertical rod, the lower end of the vertical rod is sleeved with a second spring, the second spring is located between the movable disk and the bottom plate, an upper extension sleeve is installed at the center of the movable disk, the upper end of the upper extension sleeve is installed with a lower disk, the upper end of the lower disk is installed with a suction box, the suction box is located in the middle hole, the suction box is circular in structure, and has a cavity inside, a plurality of suction eyes are provided at the upper end of the suction box, a pull-out disk is movably provided in the cavity of the suction box, a rubber ring is provided on the outer periphery of the pull-out disk, a pull-out rod is provided on the pull-out disk, the pull-out rod is inserted in the upper extension sleeve, a circular groove is provided at the lower end of the pull-out rod, a third spring is installed at the upper end of the circular groove, and the lower end of the third spring is arranged at the lower end of the upper extension sleeve. A pair of waist-shaped holes are provided on the outer periphery of the upper extension sleeve, a connecting screw is inserted in the waist-shaped hole, the inner end of the connecting screw is connected to the lower end of the pull-out rod by threading, and the outer end of the connecting screw is connected to a movable seat by threading. Before cutting the sample, the waterproof membrane is placed on the upper end of the suction box, and the air in the gap between the suction box and the waterproof membrane can be sucked through the pull-out rod by moving the pull-out disk thereon, so that this part of the air is located in the cavity, and the pressure outside the waterproof membrane is made greater than the pressure between the gaps through suction, thereby achieving the purpose of positioning the waterproof membrane, and because the suction box is located at the upper end when placed, after the waterproof membrane is adsorbed, the waterproof membrane can be pulled downward, so that the pad and the pad ring support the waterproof membrane, so as to facilitate the later cutting operation. At the same time, when the cutting is completed, the sample will be located in the circular cutting cover, and the outer periphery of the sample will also be tightly attached to the outer periphery of the waterproof membrane sample. By suction, when the circular cutting cover moves upward, it is convenient to pull the waterproof membrane sample out of the circular cutting cover. When the circular cutting cover is completely separated from the sample, at this time, due to the action of the second spring and the third spring, the sample is lifted up, and the pull-out plate is also moved upward, thereby canceling the adsorption of the suction box on the lower side of the waterproof membrane, so as to facilitate the removal of the waterproof membrane sample.

[0011] Furthermore, a movable plate is installed on the movable seat, and the movable plate is located between the pad and the bottom plate. A plurality of guide holes are opened on the movable plate, and the middle support rod passes through the guide holes. Rectangular holes are opened at both ends of the movable plate. Inner long holes are opened at both ends of the movable plate, and outer long holes are opened at the outer ends of the inner long holes, and the width of the inner long holes is smaller than the width of the outer long holes. The length directions of the rectangular hole, the second strip hole, the first strip hole, the outer long hole, the outer long hole, the T-shaped slot and the third strip hole are parallel to each other.

A movable cross plate is sleeved on the acting push rod, and a vertical plate is provided on the movable cross plate extending downward, and the vertical plate is penetrated through the rectangular hole, and a pair of clamping plates are provided at the lower end of the vertical plate, and the clamping plate is clamped on the movable plate at the outer end of the rectangular hole. A pair of connecting vertical rods are installed on the movable cross plate, the connecting vertical rod is penetrated through the first strip hole, and a movable block is installed on the connecting vertical rod, and a guide penetrating rod is penetrated on the movable block, and an outer seat is installed on the outer end of the guide penetrating rod, and the outer seat is installed on the pad.

[0013] An outward push vertical plate is installed on the positioning plate, the outer wall of the outward push vertical plate is an inclined surface, the upper end of the inclined surface extends outwardly, and the inclined surface is tangent to the outer periphery of the action wheel.

[0014] A pair of chucks are arranged at the lower end of the action push rod, a gap exists between the chucks, the diameter of the chucks is larger than the width of the outer long hole, and the diameter of the action push rod is smaller than the width of the inner long hole.

[0015] When cutting the sample, the action push rod moves downward before the ring cutting cover and the positioning plate under the action of the lower pressure plate, and the chuck at the lower end of the action push rod is clamped in the inner long hole, so that the movable plate and the pull-out plate connected thereto move downward, and when the pull-out plate moves, the waterproof coiled material can be first adsorbed and fixed by the suction box, and when the connecting screw moves to the lower end of the waist-shaped hole, it will drive the suction box and the waterproof coiled material thereon to move downward to the pad and the pad ring. When the pad and the pad ring support the waterproof coiled material, the chuck moves from the inner long hole to the outer long hole, and the action push rod and the movable plate are disconnected. After that, the waterproof coiled material will be positioned by the positioning plate, and the sample cutting operation will be performed through the ring cutting cover, and when cutting the sample, the first spring is compressed, thereby providing a movable space for the downward movement of the ring cutting cover and cutting. And the action push rod can move outward because the inclined surface acts on the action wheel.

[0016] Furthermore, in order to improve the flexibility of the T-shaped seat during movement, a concave seat is installed at the lower end of the T-shaped seat, and support wheels are rotatably provided at both ends of the concave seat, and the outer periphery of the support wheel is tangent to the lower wall of the lower pressure plate.

[0046] When operating this embodiment, the following steps are required to complete.

[0047] Step 1: The operator places the prepared waterproof membrane on the top of the suction box 121.

[0048] Step 2, start the hydraulic cylinder 106, and under the drive of the hydraulic cylinder 106, the lower pressure plate 107 moves downward along the axial direction of the guide rod 104, and at the initial stage of the movement of the lower pressure plate 107, the action push rod 156 and the chuck 170 thereon will be located at the inner long hole 135 due to the action of the fourth spring 163, and when the lower pressure plate 107 moves downward, the action push rod 156 will drive the movable plate 132 to move downward, and the downward movement of the movable plate 132 will drive the connecting screw 130 to move downward, and the downward movement of the connecting screw 130 will pull the drawing plate 124 downward through the drawing rod 125, and as the drawing plate 124 moves downward, The air between the suction box 121 and the waterproof membrane is sucked through the suction eye 123, and the waterproof membrane is finally fixed to the upper end of the suction box 121 after suction. After suction and fixation, the third spring 127 is in a compressed state, and the connecting screw 130 also moves to the lower end of the waist-shaped hole 129, so that the connecting screw 130 will act on the lower end of the waist-shaped hole 129. After that, as the movable plate 132 and the connecting screw 130 move downward, the suction box 121 will be pulled downward, and when moving downward, the second spring 115 will be compressed until the upper wall of the suction box 121 and the upper wall of the gasket 118 are in the same plane. When the suction is completed, the action wheel 147 will act on the inclined surface 146 of the outward push vertical plate 145, and when the suction box 121 moves downward, the action wheel 147 will move outward under the action of the inclined surface 146, and as the action wheel 147 moves outward, the clamping plate 155 will move toward the outer end of the rectangular hole 134; the action push rod 156 will move from the inner long hole 135 to the outer long hole 136; the locking cross bar 162 will be gradually pulled outward from the insertion hole 142, and finally the locking cross bar 162 will be pulled out of the insertion hole 142; finally the chuck 170 will be located at the outer long hole 136; finally the clamping plate 155 will be clamped at the outer end of the rectangular hole 134. After that, the lower pressing plate 107 moves downward under the drive of the hydraulic cylinder 106, and the ring cutting cover 138 cuts the fixed waterproofing coiled material. During the cutting process, the fourth spring 163 is compressed until the waterproofing coiled material cutting operation is completed. After cutting, the lower end of the ring cutting cover 138 is inserted into the annular gap. During the cutting process, since the positioning plate 144 is in a stationary state, the action wheel 147 is always close to the upper end of the inclined surface 146, so that the action push rod 156 will not move along the length direction of the second strip hole 113, but can only move downward along the axial direction of the action push rod 156, and when moving, the lower end of the action push rod 156 passes through the avoidance hole 102 set on the bottom plate 100. During the cutting process, since the action wheel 147 will not move, the positioning effect of the suction box 121 on the waterproofing coiled material will be ensured until the cutting is completed.

[0049] Step 3, when the cutting is completed, the lower pressure plate 107 moves upward under the drive of the hydraulic cylinder 106, and during the movement, it drives the push rod 156 and the ring-cut cover 138 to move upward, and separates the ring-cut cover 138 from the cut sample, and removes the sample from the ring-cut cover 138. When the sample is moved out of the annular cover 138, the lower pressure plate 107 will act on the limit head 141, so that the lower pressure plate 107 will pull the positioning plate 144 to move upward. When the positioning plate 144 moves upward, the inclined surface 146 will gradually cancel the effect on the action wheel 147, so that the action wheel 147 and the action push rod 156 connected thereto will move inward, and at this time the chuck 170 will be located at the inner long hole 135, and the chuck 155 will move into the rectangular hole 134. After that, the pull-out plate 124 will recover under the action of the second spring 115 and the suction box 121 under the action of the third spring 127. After that, the suction box 121 will lose the suction and fixation of the waterproof membrane sample, and the sample will be lifted up by the suction box 121, and finally the sample will be removed from the suction box 121.
