Description

Technical Field

[0001] The invention belongs to the field of composite membrane filter hole punching, and in particular relates to a large-aperture geocomposite membrane filter hole punching device. Background Art

[0002] Large-pore geocomposite membrane is usually a geosynthetic material made of polypropylene or other materials with a larger pore structure. Compared with conventional geomembranes, this composite membrane has a larger pore size and can better penetrate and permeate water. This composite membrane is usually used for groundwater drainage and filtration to improve soil drainage performance and prevent soil erosion. In geotechnical engineering, large-pore geocomposite membrane can improve soil drainage performance, filtration function and stability, and protect the safety and stability of engineering structures and the soil itself.

[0003] At present, large-aperture geocomposite membrane filters are mainly punctured by needles. During the puncturing process, the geocomposite membrane needs to be intermittently moved. However, the intermittent movement reduces the transmission efficiency of the geocomposite membrane to a certain extent. At the same time, the moment the needle pierces the geocomposite membrane, it is easy to cause tears around the holes in the geocomposite membrane. After puncturing the holes, the separation between the needle and the geocomposite membrane can easily cause the geocomposite membrane around the holes to bulge upward, generating pulling force around the holes and easily causing deformation of the geocomposite membrane.

[0004] Therefore, in order to improve the effect of perforating the geocomposite membrane filter without affecting the transmission efficiency of the geocomposite membrane, the present invention provides a large-aperture geocomposite membrane filter perforating device. Summary of the invention

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-8 This application is further described in detail.

[0028] Please refer to Figure 1 and Figure 5 A large-aperture geocomposite membrane filter perforating device comprises a support frame 1, the upper end of the support frame 1 is divided into three sections from left to right, and the three sections are respectively an input section 11, a perforating operation section 12 and an output section 13; the input section 11 and the output section 13 are symmetrical structures, and the upper end surfaces of the support frame 1 in the input section 11 and the output section 13 are provided with lower film rollers 14 for uniform rotation through bearings, and die roller assemblies 15 are provided in the input section 11 and the output section 13; the die roller assembly 15 corresponds to the lower film roller 14 located at the outermost side.

[0029] Please refer to Figure 2 The front and rear side walls of the support frame 1 in the piercing operation area 12 are symmetrically provided with strip grooves 16; the bottom of the support frame 1 in the piercing operation area 12 is symmetrically provided with through grooves 17.

[0030] Please refer to Figure 1 and Figure 8The upper end surface of the support frame 1 in the piercing operation section 12 is an isosceles trapezoidal structure, and the front and rear end surfaces of the support frame 1 in the piercing operation section 12 are both provided with inverted isosceles trapezoidal grooves 18; a guide plate 19 is installed on the isosceles trapezoidal groove 18 at a position close to the output section 13 through a torsion spring, and the guide plate 19 can only rotate counterclockwise, and a piercing mechanism 2 is slidably arranged in the two opposite isosceles trapezoidal grooves 18, and a guide mechanism 3 for guiding the piercing mechanism 2 is arranged directly below the piercing mechanism 2, and the guide mechanism 3 is slidably arranged at the isosceles trapezoidal structure on the upper end surface of the support frame 1.

[0031] Please refer to Figure 2 The support frame 1 is internally provided with a driving mechanism 4 for synchronously linking the piercing mechanism 2 and the guiding mechanism 3 .

[0032] Please refer to Figure 1 A lifting mechanism 5 for supplementing the displacement of the geocomposite membrane passing through is arranged inside the hole-piercing operation area 12 , and the lifting mechanism 5 cooperates with the guiding mechanism 3 .

[0033] Please refer to Figure 1 and Figure 4 The inclination angle of the hypotenuse of the isosceles trapezoidal structure on the upper end surface of the support frame 1 is the same as the inclination angle of the hypotenuse of the isosceles trapezoidal groove 18, and the positions of the hypotenuse correspond to each other.

[0034] When the geocomposite membrane is pierced with holes, the geocomposite membrane is first passed through the input section 11, the piercing section 12 and the output section 13 from left to right in sequence; and the geocomposite membrane is kept between the die roller assembly 15 and the lower film roller 14, and the die roller assembly 15 is adjusted at the same time (the die roller assembly 15 here is the prior art) so that the spacing between the die roller assembly 15 and the lower film roller 14 is consistent with the thickness of the geocomposite membrane; the piercing mechanism 2 and the guide mechanism 3 are controlled by the driving mechanism 4 to move periodically from left to right, and the movement rate is kept consistent with the transmission rate of the geocomposite membrane. In the process of the piercing mechanism 2 and the guide mechanism 3 moving from left to right, the two will fit together to press the geocomposite membrane in the middle, and then the geocomposite membrane is pierced with holes by the piercing mechanism 2. During the piercing process, the guide mechanism 3 is used for guidance to ensure that the pierced filter membrane holes have uniform pore sizes and avoid tearing and pulling of the geocomposite membrane around the holes to cause damage.

[0035] When it is necessary to change the hole spacing between the filter membrane punctures along the conveying direction of the geocomposite membrane, the return speed of the puncturing mechanism 2 and the guiding mechanism 3 from right to left can be changed by the driving mechanism 4 to control it.

[0036] Please refer to Figure 1 , Figure 2 and Figure 7The driving mechanism 4 includes a reduction motor 41 arranged on the lower end surface of the support frame 1, and the output shaft of the reduction motor 41 is equipped with a bidirectional lead screw 42. The two sides of the bidirectional lead screw 42 are respectively installed on ear plates 43 through bearings, and the ear plates 43 are fixedly arranged on the lower end surface of the support frame 1; a transverse plate 44 is threadedly connected to the bidirectional lead screw 42, and the transverse plate 44 is limitedly slidably arranged on the lower end surface of the support frame 1, and L-shaped angle plates 45 are respectively installed at the front and rear ends of the transverse plate 44.

[0037] When the driving mechanism 4 is working, the reduction motor 41 first drives the bidirectional lead screw 42 to rotate, and the bidirectional lead screw 42 drives the transverse plate 44 to move horizontally back and forth, and indirectly drives the piercing mechanism 2 and the guiding mechanism 3 to move horizontally synchronously through the L-shaped angle plate 45.

[0038] Please refer to Figure 4 and Figure 6 The lifting mechanism 5 includes a lifting plate 51 symmetrically arranged on the left and right sides of the piercing operation area 12. The lifting plate 51 is slidably arranged inside the support frame 1 up and down, and a roller 52 is provided at the upper end of the lifting plate 51 by a sliding fit. The roller 52 rolls with the conveyed geocomposite membrane to reduce friction. A push rod 53 is provided at the lower end of the lifting plate 51. A right-angled trapezoidal groove 54 with an inclined surface facing upward is opened on the push rod 53, and balls are evenly arranged on the inclined surface of the right-angled trapezoidal groove 54.

[0039] Please refer to Figure 1 and Figure 6 The support frame 1 in the piercing operation area 12 is provided with an installation cavity inside, and the lifting mechanism 5 also includes a push frame 55 arranged inside the installation cavity by limited sliding along the left and right directions. The push frame 55 is composed of a U-shaped plate 551 and two horizontal plates 552 respectively connected to the two vertical sections of the U-shaped plate 551. The end of the horizontal plate 552 can be moved to the piercing operation area 12, and the end of the horizontal plate 552 cooperates with the guide mechanism 3.

[0040] Please refer to Figure 4 and Figure 6 The outer walls of the two vertical sections of the U-shaped plate 551 that are away from each other are both embedded with a No. 1 magnetic block 553, and two No. 2 magnetic blocks 554 that respectively match the corresponding No. 1 magnetic blocks 553 are symmetrically arranged inside the installation cavity, and the lower end surface of the horizontal section of the U-shaped plate 551 is evenly provided with latch teeth.

[0041] Please refer to Figure 4 and Figure 6The lifting mechanism 5 also includes a rotating shaft 56 rotatably arranged in the middle of the installation cavity, on which a No. 1 gear plate 57 and a No. 2 gear plate 58 are fixedly arranged respectively, and the No. 1 gear plate 57 is meshed with the latch teeth, and two rack rods 59 are symmetrically meshed with the No. 2 gear plate 58 as the center inside the installation cavity. The two rack rods 59 are both slidably arranged inside the installation cavity, one end of the rack rod 59 is located in the right-angled trapezoidal groove 54 on the corresponding side, and the end of the rack rod 59 located in the right-angled trapezoidal groove 54 is fixedly provided with a wedge block 50 that cooperates with the ball on the inclined surface of the right-angled trapezoidal groove 54; the other end of the rack rod 59 is limitedly slidably arranged inside the other rack rod 59.

[0042] When the guide mechanism 3 is at the leftmost side of the piercing operation interval 12, the guide mechanism 3 drives the horizontal plate 552 on the left side to move to the left until the right end of the horizontal plate 552 on the left side is flush with the left side wall of the installation cavity. In the process of the horizontal plate 552 driving the U-shaped plate 551 to move to the left, it will drive the No. 1 gear plate 57 to rotate counterclockwise through the latch teeth, further drive the rotating shaft 56 to rotate counterclockwise, and at the same time drive the No. 2 gear plate 58 to rotate counterclockwise, and the two rack rods 59 approach each other synchronously. At this time, the wedge block 50 is gradually separated from the inclined surface of the right-angled trapezoidal groove 54, so that the lifting plate 51 descends under the action of its own gravity until the wedge block 50 is completely separated from the inclined surface of the right-angled trapezoidal groove 54. At this time, the right end of the horizontal plate 552 on the left side is flush with the left side wall of the installation cavity, and the No. 1 magnetic block 553 and the No. 2 magnetic block 554 on the left side fit together and are completely adsorbed.

[0043] During the process of the guide mechanism 3 moving from left to right until the guide mechanism 3 contacts the horizontal plate 552 on the right, the lifting plate 51 is always in a stationary state; in the process of contacting the horizontal plate 552 on the right and pushing it to the right, the No. 1 gear plate 57 is driven to rotate clockwise through the latch teeth, indirectly driving the two rack rods 59 away from each other, so that the wedge block 50 and the inclined surface of the right-angled trapezoidal groove 54 gradually approach each other until the upper end of the lifting plate 51 is pushed out.

[0044] Please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 The guiding mechanism 3 includes a frame sleeve 31 which is slidably arranged on the upper end surface of the support frame 1 located in the piercing operation area 12; a limit plate 32 is clamped on the frame sleeve 31, and limit holes are evenly arranged on the limit plate 32; a telescopic component 33 is symmetrically hinged at the lower end of the frame sleeve 31, and the telescopic component 33 is slidably arranged inside the through groove 17.

[0045] Please refer to Figure 7The telescopic assembly 33 includes a telescopic sleeve 331 and a fixed rod 332 slidably arranged inside the telescopic sleeve 331. The fixed rod 332 is located inside the telescopic sleeve 331 and is provided with a spring on the outer wall of the rod body. The upper end of the spring is in conflict with the upper end of the fixed rod 332, and the lower end of the spring is in conflict with the lower end of the telescopic sleeve 331. The telescopic sleeve 331 is connected to the frame 31 through a pin shaft.

[0046] When the guiding mechanism 3 moves from left to right or from right to left, since the frame sleeve 31 is slidably set in the isosceles trapezoidal structure position on the upper end surface of the support frame 1, the frame sleeve 31 will first rise along the inclined surface of the isosceles trapezoidal structure, then reach the upper horizontal surface of the isosceles trapezoidal structure to move horizontally for a distance, and finally move downward along the inclined surface on the opposite side. When the frame sleeve 31 moves along the above-mentioned trajectory, the frame sleeve 31 moves up and down relative to the position of the fixed rod 332, and the height difference of the frame sleeve 31 is compensated by the coordinated extension and retraction of the fixed rod 332 and the telescopic sleeve 331.

[0047] Please refer to Figure 1 , Figure 2 and Figure 7 The punching mechanism 2 includes a slotted plate 21 slidably arranged inside the strip groove 16, and a mounting frame 22 that slides up and down is commonly arranged between the two slotted plates 21. The front and rear ends of the mounting frame 22 are provided with guide rods 23 located inside the isosceles trapezoidal groove 18, and the guide rods 23 are slidably connected with the slotted plate 21 and penetrated; a top plate 24 is clamped inside the mounting frame 22, and a plurality of electric push rods 25 are installed at the lower end of the top plate 24. The lower end of the electric push rod 25 is connected to a push plate 26, and a punching needle 27 is installed at the lower end of the push plate 26 by bolts, and the punching needle 27 cooperates with the limiting hole; the fixing rod 332 located on the same side of the bidirectional lead screw 42 and the slotted plate 21 are connected by an L-shaped angle plate 45.

[0048] When the punching mechanism 2 moves, the slot plate 21 reciprocates along the strip groove 16. When the slot plate 21 moves from left to right, the guide rod 23 moves along the lower section of the isosceles trapezoidal groove 18. After the guide rod 23 moves to the position of the guide plate 19, it cooperates with the guide plate 19. The guide plate 19 opens until the guide rod 23 passes over the guide plate 19. After that, the guide plate 19 is reset by the action of the torsion spring. At this time, the guide rod 23 is located in the upper section of the isosceles trapezoidal groove 18 and moves from right to left until it moves to the leftmost end and repeats the above-mentioned cycle.

[0049] During the movement of the guide rod 23 along the inverted isosceles trapezoidal groove 18, the guide rod 23 drives the mounting frame 22 to first descend along the hypotenuse of the isosceles trapezoidal groove 18, then move to the horizontal position of the lower end of the isosceles trapezoidal groove 18 and move horizontally to the right, then rise along the hypotenuse on the other side to the horizontal position of the upper end of the isosceles trapezoidal groove 18, and finally move horizontally to the left, thereby completing the circular motion.

[0050] Since the guiding mechanism 3 and the punching mechanism 2 are connected by the L-shaped angle plate 45, the guiding mechanism 3 and the punching mechanism 2 are always synchronized when performing lateral displacement. Since the inclination angle of the hypotenuse of the isosceles trapezoidal structure on the upper end face of the support frame 1 is the same as the inclination angle of the hypotenuse of the isosceles trapezoidal groove 18 and the positions of the hypotenuses correspond, the guiding mechanism 3 and the punching mechanism 2 are also synchronized when performing longitudinal displacement.

[0051] During the movement of the frame sleeve 31 and the mounting frame 22 from left to right, the frame sleeve 31 and the mounting frame 22 first approach each other until they fit together to clamp the geocomposite membrane passing therebetween, and then continue to move to the right synchronously. At this time, the piercing mechanism 2 remains stationary relative to the position of the piercing holes on the geocomposite membrane, and the electric push rod 25 performs a telescopic movement to drive the piercing needles 27 to complete a single-row piercing operation on the geocomposite membrane; since the position of the piercing needles 27 for piercing the geocomposite membrane is always relatively stationary, the piercing effect can be effectively guaranteed, thereby avoiding the geocomposite membrane around the filter membrane hole from bulging upward during the separation process from the geocomposite membrane, causing the geocomposite membrane to deform.

[0052] And because the geocomposite membrane will be pressed down by the mounting frame 22 during the process of the frame sleeve 31 and the mounting frame 22 being fitted to each other, and the geocomposite membrane will be clamped in cooperation with the frame sleeve 31, the geocomposite membrane will tend to be stretched and tensioned during the clamping process; at this time, the displacement of the geocomposite membrane is supplemented by the aforementioned lifting plate 51 descending to support the geocomposite membrane; to avoid stretching damage to the geocomposite membrane, when the mounting frame 22 is completely separated from the geocomposite membrane, the lifting plate 51 rises and continues to support the geocomposite membrane, thereby keeping the geocomposite membrane in a tensioned state at all times.

[0053] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
