Description

Technical Field

[0001] This invention relates to the field of thin film processing equipment technology, and in particular to a special film machine for water-permeable and moisture-retaining tree planting. Background Technology

[0002] In agriculture, landscaping, and some construction projects, water-permeable and moisture-retaining films are frequently needed for moisture retention and maintenance. Traditional films often require manual perforation to achieve this function, which is inefficient and struggles to ensure uniform perforation. Existing perforation equipment is not only complex and costly, making it unsuitable for small businesses or individual farmers, but also produces unsatisfactory perforation results, failing to meet the practical requirements for film permeability. Therefore, designing a simple, easy-to-operate, and highly efficient dedicated film permeation and moisture retention machine is of significant practical importance. Summary of the Invention

[0003] The purpose of this invention is to provide a special membrane machine for water-permeable and moisture-retaining tree planting, so as to solve the problems of low efficiency, poor uniformity and complex structure of existing membranes.

[0004] To achieve the above objectives, the present invention provides a special membrane machine for water-permeable and moisture-retaining tree planting, comprising a frame body, a perforation execution component, a film fixing component, and an opening and cutting component; The main frame consists of a tabletop and four supporting legs, with a punched base fixed to the top of the tabletop. The drilling execution component includes a fixed frame arranged parallel above the desktop, with the bottom of the fixed frame fixedly connected to the desktop; a first telescopic hydraulic cylinder is vertically installed between the fixed frames, with the piston rod end of the first telescopic hydraulic cylinder fixedly connected to the top center of the drilling disc; and several drilling columns are vertically fixed to the bottom of the drilling disc, each drilling column being a frustum shape with a small opening at the bottom and a large opening at the top. The top of the punching disc has through holes corresponding to the positions of each punching post. The inner diameter of the through holes at the top of the punching disc is the same as the inner diameter of the top of the punching post, so that the circular waste film produced by punching falls off along the through holes. The telescopic cylinder can drive the punching disc to drive the punching post and the opening knife on the long strip knife holder to smoothly impact the film to be opened, so as to realize the one-time punching and opening of the film between the punching seat and the punching disc. The film fixing assembly includes a fixing plate and a second telescopic cylinder. The second telescopic cylinder is vertically installed at the bottom of the fixing frame, and the piston rod end of the second telescopic cylinder is fixedly connected to the top of the fixing plate. The opening cutting assembly includes a long strip-shaped blade holder fixedly disposed at the bottom of the punching disc.

[0005] Preferably, there are two fixing frames, and a control box is provided on the top of the fixing frame. The control box is provided with two control switches, which are electrically connected to the first telescopic cylinder and the second telescopic cylinder, respectively.

[0006] Preferably, the punching posts and the long strip-shaped tool holder are distributed in a star-shaped pattern at the bottom of the punching disc, and all the punching posts are at the same height.

[0007] Preferably, the material of the perforated post is 440C stainless steel or 420 stainless steel, the height of the perforated post is 60-65mm, the inner diameter of the top end is 11-13mm, and the inner diameter of the bottom end is 8-10mm.

[0008] Preferably, an elastic buffer layer is attached to the bottom of the fixing plate. The elastic buffer layer is made of silicone or rubber and has a thickness of 10-15mm. This layer is used to prevent damage to the film when the fixing plate presses against it.

[0009] Preferably, there are two fixed plates and two second telescopic cylinders. The two second telescopic cylinders are controlled by the same control switch. The length of the fixed plate is adapted to the width of the table and is located on both sides directly above the punching seat. The second telescopic cylinders can drive the fixed plate to rise and fall to press or release the film to be punched.

[0010] Furthermore, both the first and second telescopic cylinders are equipped with pressure regulating valves. The pressure regulating valves can adjust the cylinder output pressure according to the material of the diaphragm (plastic diaphragm or composite diaphragm), and the pressure adjustment range is 0.5-2MPa.

[0011] Preferably, the top of the desktop is provided with positioning scale lines, which are distributed along the edge of the punching base to assist the operator in quickly aligning the position of the film to be punched with the punching groove.

[0012] Preferably, the elongated blade holder is located on one side of the punching column and is parallel to the edge of the punching disc; the top of the elongated blade holder is welded and fixed to the bottom of the punching disc, and a cutting groove extending along the length of the blade holder is provided at the bottom.

[0013] Preferably, both ends of the cutter groove are provided with internal threaded holes, and fastening bolts are adapted to be installed in the internal threaded holes; an opening blade is detachably installed in the cutter groove, the blade of the opening blade faces the direction of the punching seat, and is fixed by the fastening bolts at both ends.

[0014] Furthermore, when the first telescopic cylinder drives the drilling disc to descend, the opening knife can move down synchronously with the drilling disc to cut open one corner of the water-permeable membrane to be drilled, forming an opening that is easy to fit onto the tree root.

[0015] Furthermore, the top of the perforating disc is also provided with a waste collection cover. The waste collection cover is funnel-shaped, with the bottom of the cover communicating with the through hole and the top provided with a detachable collection box for collecting the circular waste film sheets that fall off from the through hole.

[0016] Preferably, two transverse reinforcing rods are fixedly connected between the two fixing frames, and the number of transverse reinforcing rods is two, which are evenly distributed along the height direction of the fixing frames to improve the overall structural stability of the fixing frames.

[0017] Therefore, the present invention employs the above-mentioned water-permeable and moisture-retaining special film machine for tree planting, and the beneficial effects are as follows: The highly efficient perforation system, utilizing a cross-shaped perforation column and a telescopic hydraulic cylinder, enables multiple perforations to be made on the film simultaneously, significantly improving work efficiency compared to manual perforation. For example, traditional manual perforation methods might only be able to perforate fifty films per hour, while the film machine of this invention can perforate five thousand films per hour, increasing efficiency by a hundredfold. Furthermore, it simultaneously creates openings while perforating, improving the efficiency of water seepage and moisture retention operations for construction workers by more than tenfold.

[0018] It has good stability. The fixing plate at the bottom of the fixing frame fixes the film through the second telescopic hydraulic cylinder, ensuring that the film will not be displaced during the punching process, thus ensuring the accuracy and uniformity of punching and improving product quality.

[0019] With a simple structure, the overall structure adopts a frame design. The main components include table legs, punching base, fixing frame, telescopic cylinder, punching plate, etc. Each component has a simple structure, is easy to manufacture and maintain, and reduces equipment costs.

[0025] Example 1 like Figure 1 As shown, this invention provides a special membrane machine for permeable and moisture-retaining tree planting, including a frame body, a perforation execution component, a film fixing component, and an opening and cutting component. It is specifically designed for agricultural and landscaping tree planting scenarios, used for one-time perforation and opening cutting of permeable membranes. The processed membrane can be directly applied to the tree roots to achieve the function of permeable and moisture-retaining properties. The overall size of the equipment is suitable for small-scale operations; the tabletop 1 is 1200mm long and wide, and the machine weighs approximately 80kg, allowing it to be manually transported to the tree planting site for temporary operation.

[0026] The tabletop 1 in the main frame is made of 10mm thick Q235 steel plate with electrostatic spraying for rust prevention. The supporting legs 2 are made of 50mm diameter seamless steel pipes with anti-slip rubber pads installed on the bottom. The anti-slip rubber pads are 1 meter long and wide, and 12mm thick, which can effectively prevent the equipment from sliding during operation. The punching base 3 is a cuboid structure made of nylon, which is lightweight and wear-resistant.

[0027] The fixing frame 4 in the drilling execution component is a U-shaped steel structure with the opening facing downwards. The two fixing frames 4 are 600mm apart and are fixed to the tabletop 1 by expansion bolts. The first telescopic cylinder 6 is a single-acting hydraulic cylinder with a cylinder diameter of 40mm, a stroke of 150mm, and a rated working pressure of 2MPa. It is powered by a matching hydraulic pump station (power 0.75kW). The hydraulic pump station is placed at the bottom of the tabletop 1 and is fixedly connected to the table leg 2.

[0028] like Figure 2As shown, the perforated plate 9 is a circular steel plate, and the perforated column 10 welded to the bottom is made of stainless steel. The perforated column 10 is a frustum shape with a small opening at the bottom and a large opening at the top. The perforated column 10 is made of 440C stainless steel, with a height of 60mm, an inner diameter at the top of 13mm, an inner diameter at the bottom of 10mm, an outer diameter at the top of 15mm, and an outer diameter at the bottom of 12mm. The inner diameter of the through hole 11 at the top of the perforated plate 9 is the same as the inner diameter of the top of the perforated column 10, facilitating the discharge of debris. The waste collection cover is made of plastic, and the diameter of the funnel opening is the same as the diameter of the perforated plate 9. The collection box is connected to the cover body by a buckle, making it easy to disassemble and clean.

[0029] In the membrane fixing assembly, the second telescopic cylinder 7 is a small single-acting hydraulic cylinder with a diameter of 25mm and a stroke of 80mm. The two second telescopic cylinders 7 are respectively installed at the bottom of the fixing frame 4. The fixing plate 8 is a rectangular steel plate (280mm long, 50mm wide, and 5mm thick), with a 3mm thick silicone elastic buffer layer pasted on the bottom to prevent damage to the membrane during compression. The control unit uses a PLC controller (model S7-200SMART) to synchronously control the lifting and lowering of the two second telescopic cylinders 7, ensuring uniform pressure on the fixing plate 8.

[0030] like Figure 3 As shown, the elongated blade holder 13 in the opening cutting assembly is made of aluminum alloy and is welded to the bottom edge of the punching disc 9. Specifically, the punching posts 10 and the elongated blade holder 13 are arranged in a star-shaped pattern at the bottom of the punching disc 9, with the elongated blade holder 13 staggered from the punching posts 10 to avoid interference. The opening blade 12 is made of high-speed steel, and the blade is hardened (hardness HRC58-62), ensuring sharpness that meets the requirements for film cutting.

[0031] The bottom of the elongated blade holder 13 has a cutting groove extending along the length of the blade holder. Both ends of the groove wall have internal threaded holes 14, and fastening bolts 15 are fitted into the internal threaded holes 14. The opening blade 12 is fixedly installed on the elongated blade holder 13 by the fastening bolts 15 and the internal threaded holes 14. The opening blade 12 can be disassembled and replaced after a period of use. The fastening bolts 15 are M6 hexagon socket head cap bolts, with matching spring washers to prevent loosening.

[0032] The pressure regulating valve in the auxiliary components is a manual regulating type (adjustment range 0.5-2MPa), which is installed in the oil inlet pipes of the first telescopic cylinder 6 and the second telescopic cylinder 7 respectively; the positioning scale line on the top of the table 1 is laser engraved (line width 0.5mm), distributed along the edge of the punch seat 3, with a scale accuracy of 1mm, to help the operator quickly align the film.

[0033] The specific operation procedure is as follows: (a) Preparatory work.

[0034] Connect the equipment power supply (AC220V) and the hydraulic pump station power supply, start the pump station, and check whether the lifting and lowering of the first telescopic cylinder 6 and the second telescopic cylinder 7 are smooth (no jamming or oil leakage); preset the pressure through the pressure regulating valve: adjust the pressure of the first telescopic cylinder 6 to 1.5MPa, which is suitable for a diaphragm thickness of 0.15mm, and adjust the pressure of the second telescopic cylinder 7 to 0.8MPa to avoid damaging the diaphragm.

[0035] Next, prepare the permeable membrane (made of PE composite film, 0.15mm thick) to be processed, and cut it to a size of 1.2m×1.0m according to the tree planting requirements, ensuring that the edges of the membrane are flat (without wrinkles or damage).

[0036] (ii) Film positioning and fixation.

[0037] The operator lays fifty films vertically on the table 1 and adjusts the position of the films according to the positioning scale line on the top of the table 1 so that the area of ​​the film to be punched covers the top of the punching base 3 and the corner to be cut is aligned with the bottom of the long strip knife holder 13, ensuring that the opening after cutting is located in the corner of the film, which is convenient for attaching tree roots.

[0038] The top of the mounting bracket 4 is equipped with a control box 5. When the "fixed start" button on the controller 5 is pressed, the two second telescopic cylinders 7 descend synchronously, driving the fixing plate 8 to press down. The silicone buffer layer adheres to the surface of the film, and the film is tightly fixed between the punching seat 3 and the fixing plate 8 (the fixing pressure is displayed by the pressure gauge and is stable at 0.8MPa). After confirming that the film has no displacement, proceed to the next step of operation.

[0039] (iii) Drilling and corner cutting.

[0040] Press the "Drill Start" button, and the first telescopic cylinder 6 drives the drilling disc 9 to descend at a constant speed (descent speed 50mm / s). During this process, the drilling column 10 first contacts the film, and as the first telescopic cylinder 6 descends, it drives the drilling column 10 to drill several evenly distributed seepage holes on the film in one go. Meanwhile, the opening knife 12 on the long strip knife holder 13 descends with the punching disc 9 to cut a 200mm long opening in the film; the circular waste film produced by punching falls into the debris collection cover through the through hole 11 at the top of the punching disc 9 and is eventually collected in the collection box.

[0041] When the punching disc 9 descends to its lowest position, the first telescopic cylinder 6 automatically stops descending, maintaining pressure for 1 second to ensure thorough punching and a smooth cut.

[0042] (iv) Removal and repositioning of finished products.

[0043] Press the "Reset" button, and the first telescopic cylinder 6 will drive the punching plate 9 to rise at a constant speed until it returns to the initial position; then, the second telescopic cylinder 7 will drive the fixing plate 8 to rise and loosen the fixation of the film.

[0044] The operator removes the processed film from table 1 and checks the integrity of the seepage holes (no burrs, no unopened holes) and the flatness of the openings (no tears at the opening edges). If it meets the requirements, it is placed in the finished product stacking area. If there are defects (such as unopened holes), it is adjusted and reprocessed.

[0045] After each processing period, open the collection box of the debris collection hood, clean the waste film inside to avoid clogging the through hole 11; after cleaning, close the collection box and continue processing the next batch.

[0046] Therefore, the present invention adopts the above-mentioned water-permeable and moisture-retaining special film machine for tree planting, which effectively solves the problems of low film perforation efficiency, poor uniformity and complex equipment structure in the prior art, and is suitable for the use needs of tree planting scenarios, and has high practicality and promotion value.

[0047] It is worth noting that all the contents not described in detail in this invention are existing technologies and are well known to those skilled in the art.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
