Description

Technical Field

[0001] The invention relates to the technical field of composite geomembrane production and processing, in particular to a composite geomembrane transverse water sprinkling and edge throwing device. Background Art

[0002] The edge is also called the reserved edge. It means that when producing composite geomembrane, the edges of the composite geomembrane are not compounded, so that the geotextile and geomembrane are in a separated state. The purpose is to facilitate welding operations during construction, especially large-area laying and splicing. When welding the geomembrane after the edge treatment, workers can directly overlap the exposed geomembrane together and use a geomembrane welder for welding, thereby improving construction efficiency and quality.

[0003] Existing edge throwing treatments are often divided into transverse edge throwing and longitudinal edge throwing according to the requirements of the edge throwing. The transverse edge throwing refers to the edge throwing treatment of the transverse position of the geotextile by a specific device before the geotextile and geomembrane are compounded, while the longitudinal edge throwing refers to the edge throwing treatment of the longitudinal side position of the geotextile by a specific device before the geotextile and geomembrane are compounded.

[0004] In the existing lateral edge-flipping process of composite geomembrane, the geotextile is usually cooled by sprinkling water. Although this can ensure that the geotextile and geomembrane can remain separated at the edge-flipping position, in actual operation, when cooling water is sprinkled on the geotextile, the wetted area of ​​the geotextile often takes on an irregular shape during the water absorption process, resulting in the inability to accurately control the width of the edge-flipping according to construction requirements.

[0044] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0045] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, in an embodiment of the present invention, a composite geomembrane transverse water spraying and edge throwing device comprises a processing table 1, on which a conveying structure 2, an edge throwing structure 3 and a pressing structure 7 are installed;

[0046] The conveying structure 2 includes two sets of conveying wheels 201, which are rotatably mounted on the processing table 1, and the upper ends of the two sets of conveying wheels 201 are used to support and convey the geotextile 4;

[0047] The swinging edge structure 3 is arranged between the two groups of conveying wheels 201, and is used to spray water and cool the geotextile 4 conveyed by the conveying structure 2. It includes a swinging frame 303, and the swinging frame 303 is slidably installed on a positioning track 306 arranged on the upper part of the processing table 1 through a sliding base 3024. The positioning track 306 is provided with a driving component 302 for driving the swinging frame 303 to move along the conveying speed of the geotextile 4. Two groups of sealing boxes 301 are mirror-arranged in the vertical direction in the swinging frame 303. The two groups of sealing boxes 301 are mirror-arranged in the vertical direction. 01 are both provided with openings on the near side, the long side width of the openings is consistent with the width of the geotextile 4, the two groups of sealed boxes 301 are driven by the lifting assembly 304 installed in the swing frame 303 to move in a mirror image, and the two groups of sealed boxes 301 are both provided with a group of clamping assemblies, and the two groups of clamping assemblies are used to cooperate with the two groups of sealed boxes 301 to adjust the clamping and watering width of the geotextile 4, wherein the negative pressure assembly is installed in the upper sealed box 301, and the spray assembly 308 is installed in the lower sealed box 301;

[0048] The pressing structure 7 is arranged on the conveying side of the conveying structure 2 and is used for pressing and pasting the geotextile 4 and the geomembrane 5;

[0049] Specifically, the present invention improves the swinging edge structure 3 and sets a swinging frame 303 that can move at the same speed as the geotextile 4 in the conveying structure 2, so that the two sets of sealing boxes 301 in the swinging frame 303 are relatively stationary with the geotextile 4 when they are close to and clamped on both sides of the geotextile 4, so that the geotextile 4 can be sprayed with water to cool down without affecting the conveying requirement of the geotextile 4;

[0050] At the same time, the present invention provides a set of clamping components in two sets of sealing boxes 301, and the two sets of clamping components are used to cooperate with the two sets of sealing boxes 301 to adjust the clamping and watering width of the geotextile 4, so as to meet the requirements of different edge width specifications;

[0051] The present invention arranges a negative pressure component and a spray component 308 in the upper and lower sealed boxes 301 respectively. When the spray component 308 sprays the bottom of the geotextile 4, the negative pressure component is started to generate a negative pressure state in the upper sealed box 301, thereby improving the penetration efficiency of the water on the geotextile 4.

[0052] like Figure 3 , Figure 4 as well as Figure 5As shown, in the embodiment of the present invention, the clamping assembly includes two groups of clamping plates 311 and a driving member, the two groups of clamping plates 311 are mirror-imaged on both sides of the sealing box 301 in the width direction, the clamping plates 311 are slidably installed in the sealing box 301 in the vertical direction, and each clamping plate 311 is elastically connected to the sealing box 301 through a corresponding No. 1 elastic member, wherein the No. 1 elastic member is preferably a No. 1 connecting spring 313, and the No. 1 connecting spring 313 is used to elastically drive the corresponding clamping plate 311 to move in a direction away from the opening of the sealing box 301, and the driving member is used to drive the clamping plates 311 at the mirror-image corresponding positions in the two groups of clamping plates 311 to move linearly, and the linear movement direction of each group of clamping plates 311 moves from the outside to the inside in sequence, and while the inner clamping plate 311 moves, its adjacent outer clamping plate 311 maintains a state of clamping the geotextile 4;

[0053] Specifically, in the present invention, the number of clamping plates 311 in each clamping assembly is eight, and four are provided on each side of the sealing box 301. Of course, in actual design, the number and width of the clamping plates 311 in each clamping plate group 311 can be flexibly adjusted according to actual conditions, and the present invention does not impose a rigid requirement. The present invention provides a group of positioning protrusions 3111 on both sides of the clamping plate 311, and the inner wall of the wide end side plate of the sealing box 301 is hollowed out to provide a limiting groove 3011 for installing the positioning protrusion 3111. The limiting groove 3011 is A guide groove is provided inside for the end of the positioning protrusion 3111 to be inserted and slid (the guide groove is not shown in the drawings of the present invention), and multiple groups of No. 1 connecting springs 313 are fixedly received in the limiting groove 3011, and one end of the No. 1 connecting spring 313 is fixedly connected to the positioning protrusion 3111. When the clamping plate 311 of the clamping assembly is driven by the driving member to move toward the port direction of the sealing box 301, the No. 1 connecting springs 313 correspondingly connected to both sides of the clamping plate 311 are deformed accordingly, so as to provide elastic force for the clamping plate 311 to return to slide;

[0054] like Figure 4 , Figure 5 as well as Figure 6 As shown, in the embodiment of the present invention, the driving member is a driving cam rod 310, and the driving cam rod 310 includes a driving shaft 3101, and the driving shaft 3101 is rotatably installed in the corresponding sealing box 301, one end of which extends out of the sealing box 301, and is driven to rotate by an adjusting motor 315 on the outer wall of the long side plate of the sealing box 301, and two groups of incomplete cams 3102 are mirror-imaged on both sides of the shaft body of the driving shaft 3101, and each group of incomplete cams 3102 includes the same number of incomplete cams 3102 as each group of clamping plates, and the sector areas of the multiple groups of incomplete cams 3102 decrease from the outside to the inside.

[0055] And further, if Figure 5 as well as Figure 7The spray assembly 308 shown includes two groups of spray pipes 3081 and a water pump 3082. The water pump 3082 is fixedly installed at the bottom of the lower sealed box 301, and is used to store spray liquid by connecting to the corresponding bottom of the lower sealed box 301 through two groups of liquid supply pipes 3083. A group of wedge-shaped sliders 309 are fixedly installed at both ends of each group of spray pipes 3081. The inner wall of the wide side plate of the lower sealed box 301 is provided with a sliding groove for sliding installation of the corresponding two groups of wedge-shaped sliders 309. The away sides of the two groups of wedge-shaped sliders 309 are provided with inclined surfaces. The close sides of the two groups of wedge-shaped sliders 309 are elastically connected to the baffle in the middle of the sliding groove through the corresponding No. 2 elastic member, wherein the No. 2 elastic member is a No. 2 connecting spring 314.

[0056] When the width of the watering and cooling area of ​​the geotextile 4 needs to be adjusted, the multiple groups of adjusting motors 315 are controlled to start synchronously, and the multiple groups of adjusting motors 315 drive the corresponding drive shaft 3101 of the drive cam rod 310 to rotate, and simultaneously drive the multiple groups of incomplete cams 3102 installed on the drive shaft 3101 to rotate synchronously. In the present invention, the incomplete cam 3102 located on the outermost side (with the largest fan-shaped area) contacts one end of the outermost clamping plate 311, and as the incomplete cam 3102 rotates, the contacting clamping plate 311 is pushed to move toward the port of the sealing box 301. When the arc of the incomplete cam 3102 When the surface side contacts the end surface of the clamping plate 311, the clamping plate 311 moves to the extreme position at this time, and the two groups of clamping plates 311 at the corresponding positions can be fixed and pressed on both sides of the geotextile 4 to adjust the width of the water spraying and cooling area of ​​the geotextile 4. When the cam rod 310 is actually driven to rotate, the multiple groups of incomplete cams 3102 on the cam rod 310 are driven to contact the corresponding end surfaces of the corresponding clamping plates 311 in turn, and push the multiple groups of clamping plates 311 to be in a stepped state and move to the extreme position in turn, so that the width of the water spraying and cooling area of ​​the geotextile 4 is gradually shortened, thereby ensuring that the width of the water spraying and cooling area of ​​different geotextiles 4 is under;

[0057] Furthermore, in the present invention, during the driving process of the two groups of clamping plates 311, the outer clamping plate 311 reaches the limit position before the inner clamping plate 311, and during the movement of the outer clamping plate 311, the positioning protrusions 3111 at both ends of the outer clamping plate 311 can contact the inclined surface of the wedge-shaped slider 309, and when the clamping plate 311 moves toward the sealing opening direction, the wedge-shaped slider 309 is pushed to approach the center of the sealing box 301, thereby adjusting the position of the spray pipe 3081. When the spray width increases, the spacing between the two groups of spray pipes 3081 increases accordingly. Conversely, when the spray width decreases, the spacing between the two groups of spray pipes 3081 decreases accordingly, so as to meet the requirements of giving way and spraying of the spray pipe 3081 after the width adjustment.

[0058] like Figure 1As shown, in an embodiment of the present invention, the spray flow of the water pump 3082 can be controlled in multiple stages by the control panel 6 on the swing frame 303. In the present invention, when the adjustment motor 315 rotates to adjust the spray width, the area of ​​the geotextile 4 water sprinkling and cooling area is correspondingly adjusted, and the spray flow of the water pump 3082 is correspondingly controlled by the control panel 6 to ensure the quality of the spray.

[0059] like Figure 8 As shown, in the embodiment of the present invention, the driving assembly 302 includes a driving screw 3022 and a transmission block 3023. The driving screw 3022 is rotatably mounted on the positioning rail 306, and one end of the driving screw 3022 is driven to rotate by the power motor 3021. The transmission block 3023 is fixedly mounted on the lower side of the sliding base 3024 at the bottom of the swing frame 303, and is provided with an internal threaded hole that forms a spiral pair transmission connection with the driving screw 3022;

[0060] When the geotextile 4 is subjected to water spraying and cooling operation, the power motor 3021 is turned on to drive the driving screw 3022 to rotate, and the transmission block 3023 is cooperated to drive the swing frame 303 and the geotextile 4 to move at the same speed, so that the two groups of sealing boxes 301 in the swing frame 303 and the geotextile 4 are relatively still, thereby avoiding the two groups of sealing boxes 301 from causing pulling damage to the geotextile 4 when clamping the geotextile 4. In addition, rubber is installed on the open end faces of the two groups of sealing boxes 301 of the present invention to further avoid damage to the geotextile 4 during the clamping process of the sealing boxes 301. Of course, in actual design, the driving component 302 can also be replaced by other components with constant speed driving capability, such as electric drive. The present invention does not have a rigid requirement on the selection of the driving component 302.

[0061] like Figure 8 and Fig. 9 As shown, in the embodiment of the present invention, a group of mounting plates 307 are respectively installed on the far side of the two groups of sealed boxes 301, and a plurality of guide posts 305 are provided on the far side of the two groups of mounting plates 307. The upper and lower sides of the swing frame 303 are provided with guide tubes for sliding connection of the corresponding guide posts 305. In the present invention, when the lifting assembly 304 drives the two groups of mounting plates 307 and the sealed box 301 to move in a mirror image, the plurality of guide posts 305 slide along the guide tubes to ensure the stability of the mounting plates 307 and the sealed box 301 when they move.

[0062] Furthermore, the lifting assembly 304 includes a telescopic cylinder group 3041, a transmission gear 3043 and a transmission rack 3042, wherein the telescopic cylinder group 3041 is fixedly mounted on the upper side plate of the swing frame 303, and its telescopic rod is fixedly connected to the upper end of the swing frame 303, and two groups of the transmission gears 3043 are rotatably mounted on the left and right side plates of the swing frame 303 through the mounting shaft, and a group of transmission racks 3042 are respectively mounted on both sides of the two groups of mounting plates 307, and the two sides of the transmission gear 3043 are meshedly connected with the transmission racks 3042 arranged on the same side of the two groups of mounting plates 307. When the present invention realizes the mirror image movement of the two groups of sealed boxes 301, the telescopic cylinder group 3041 is extended and retracted to drive the sealed box 301 on the upper side to rise and fall, and at the same time, the transmission of the four groups of transmission racks 3042 and the two groups of transmission gears 3043 drives the sealed box 301 on the lower side to rise and fall accordingly;

[0063] Of course, in actual design, the lifting assembly 304 used can also be replaced by other components with mirror drive capabilities, such as two sets of synchronously retractable cylinder components can be selected for combination use.

[0064] like Figure 3 As shown, in an embodiment of the present invention, the negative pressure component includes a negative pressure air pump 312, and the negative pressure air pump 312 is fixedly installed on the top of the upper sealing box 301, and its exhaust pipe is connected to the outside of the sealing box 301. In the present invention, when the two groups of spray pipes 3081 are performing spraying operations, the negative pressure air pump 312 is turned on at this time to generate a negative pressure state in the upper sealing box 301, thereby improving the penetration efficiency of water on the geotextile 4. Of course, the actual negative pressure air pump 312 can also be replaced by multiple groups of exhaust fans, and the multiple groups of exhaust fans can be started synchronously to discharge the air in the upper sealing box 301 to create a negative pressure state.

[0065] like Figure 1 As shown, in an embodiment of the present invention, the pressing structure 7 includes a guide wheel 701 and two groups of pressure rollers 702, wherein the guide wheel 701 is rotatably installed on the rear side of the conveying structure 2 for guiding the geotextile 4, and the two groups of pressure rollers 702 are rotatably installed on the rear side of the guide wheel 701 for pressing and bonding the geotextile 4 and the geomembrane 5, and the geomembrane is conveyed by a conveying assembly in the existing equipment, which is not specifically described in the present invention.

[0066] In summary, the present invention improves the geotextile 4 water sprinkling and cooling component in the composite geomembrane transverse water sprinkling and edge throwing device, specifically:

[0067] 1. By setting a swing frame 303 that can move at the same speed as the geotextile 4 in the conveying structure 2, and providing a set of sealing boxes 301 on the upper and lower sides of the swing frame 303, the two sets of sealing boxes 301 can be clamped close to the two sides of the geotextile 4 and remain relatively still with the geotextile 4, so that when the geotextile 4 in the sealing box 301 is sprayed with water to cool down, the water on the geotextile 4 can only penetrate in the area sealed by the sealing box 301, avoiding the problem that the wetted area of ​​the geotextile 4 is irregular in shape during the water absorption process, which affects the quality of the swing edge;

[0068] 1.1. At the same time, the present invention installs a spray assembly 308 and a negative pressure assembly in two sets of sealed boxes 301 respectively. When the spray assembly 308 sprays one side of the geotextile 4, the negative pressure assembly generates a negative pressure state in the corresponding sealed box 301, thereby improving the water penetration efficiency through negative pressure adsorption;

[0069] 2.
