Description

Technical Field

[0001] This invention belongs to the technical field of curtain film production equipment, specifically relating to a plateless film filament injection mechanism and filament arrangement and sheet forming device. Background Technology

[0002] Currently, curtain membranes are the main product used in water treatment. Curtain membranes are highly praised for their service life and treatment efficiency, including ease of assembly and application, long service life, and excellent treatment effect. However, problems such as disordered membrane fiber arrangement, poor uniformity, and difficulty in controlling the membrane fiber spacing still seriously affect the potting and sealing effect of the membrane fibers. Furthermore, uneven membrane fibers can easily lead to sludge accumulation, reducing the service life and treatment effect of the curtain membrane.

[0003] To address issues such as sludge accumulation and poor glue injection sealing caused by uneven arrangement of membrane filaments in curtain membrane systems, Chinese patent document CN 112174262A discloses an apparatus and method for automatically forming curtains from multiple membrane filaments. This method establishes a mechanical filament arrangement device, enabling the transition from manual to mechanical filament arrangement for curtain membranes. This effectively controls the spacing of the membrane filaments and improves the anti-fouling properties of the membrane module. However, in this apparatus, after applying glue to the membrane filaments in the glue injection groove of the filament arrangement plate, the filament arrangement pressure plate needs to be manually fastened onto the filament arrangement plate and fixed to it using elbow clamps for cooling and shaping. The filament arrangement pressure plate for cooling and shaping hot melt glue is a solid metal plate, which requires manual loading and unloading, resulting in high labor intensity and poor safety. Furthermore, the glue injection process for the upper and lower pressure plates needs to be performed sequentially, thus adding extra processing time. In addition, the apparatus requires manual cutting, resulting in low production efficiency and high labor costs. Only a single membrane can be prepared per run, leading to poor continuity and low production efficiency. Summary of the Invention

The upper and lower pressure plates in the gluing mechanism operate automatically, eliminating the need for manual movement and significantly reducing labor intensity and costs.

Detailed Implementation

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] like Figure 1 As shown, a plateless membrane fiber glue injection mechanism of this embodiment includes an upper pressure plate 1, a lower pressure plate 2, a translational glue injection nozzle 3, a fixed glue injection nozzle 4, a first horizontal moving mechanism 5, a second horizontal moving mechanism 6, a rotating mechanism 7, a first vertical moving mechanism 8, and a second vertical moving mechanism 9.

[0038] The translational dispensing nozzle 3 is connected to the moving end of the first horizontal moving mechanism 5; the rotating mechanism 7 is connected to the moving end of the first vertical moving mechanism 8; the upper pressure plate 1 is connected to the rotating end of the rotating mechanism 7, and the upper pressure plate 1 is located below the translational dispensing nozzle 3.

[0039] The second vertical moving mechanism 9 is connected to the moving end of the second horizontal moving mechanism 6; the lower pressure plate 2 is connected to the moving end of the second vertical moving mechanism 9; the lower pressure plate 2 is located below the upper pressure plate 1 and is opposite to the position of the upper pressure plate 1; the fixed glue injection nozzle 4 is located above the lower pressure plate 2.

[0040] In this embodiment, the plateless membrane fiber gluing mechanism connects the sliding gluing nozzle 3 and the fixed gluing nozzle 4 to the gluing machine. After the membrane fibers are arranged, they pass through the position between the upper pressure plate 1 and the lower pressure plate 2. The gluing process of the upper pressure plate is as follows: the sliding gluing nozzle 3 is driven by the first horizontal moving mechanism 5 to move horizontally left and right to glu the upper pressure plate 1 below it. The temperature of the glue cylinder of the gluing machine is adjusted according to actual needs, preferably not exceeding 220°C. The amount of glue dispensed by the sliding gluing nozzle is adjusted according to actual conditions, preferably controlled at about 10-30g. The gluing process of the lower pressure plate is as follows: the fixed gluing nozzle 4 is fixed and glue is dispensed to the lower pressure plate 2. During the gluing process, the lower pressure plate 2 moves horizontally left and right under the drive of the second horizontal moving mechanism 6 to ensure that the glue is evenly dispensed to all parts of the lower pressure plate. During operation, the upper pressure plate 1 and the lower pressure plate 2 operate simultaneously to apply glue. After the upper and lower pressure plates have finished applying glue, the upper pressure plate rotates 180° under the drive of the rotating mechanism 7. Then, driven by the first vertical moving mechanism, the upper pressure plate and the lower pressure plate, driven by the second vertical moving mechanism, simultaneously press the glued upper and lower pressure plates onto the wire guide sheet, completing the hot melt adhesive bonding and shaping process of the wire guide sheet. The pressing time can be adjusted according to the actual situation.

[0041] The plateless film filament glue injection mechanism of this embodiment uses mechanized upper and lower pressure plates in conjunction with moving and rotating mechanisms to replace manual handling, loading and unloading of pressure plates, and filament sheet shaping process. This effectively reduces labor intensity, improves production efficiency, and enhances safety. Furthermore, the flip-up upper pressure plate enables simultaneous glue injection from both upper and lower pressure plates, further reducing process time and improving production efficiency.

[0042] The first horizontal moving mechanism 5 and the second horizontal moving mechanism 6 respectively drive the translational glue injection nozzle 3 and the lower pressure plate 2 to move horizontally. The specific structure of the horizontal moving mechanism is not limited, as long as it can perform the above actions. For example, the horizontal moving mechanism can be a linear module consisting of a horizontal slide rail, a slider, a lead screw and nut assembly, and a motor. Driven by the motor, the slider moves along the horizontal slide rail, and the translational glue injection nozzle 3 and the lower pressure plate 2 are connected to the slider.

[0043] The first vertical moving mechanism 8 and the second vertical moving mechanism 9 respectively drive the upper pressure plate 1 and the lower pressure plate 2 to move vertically. The specific structure of the vertical moving mechanism is not limited, as long as it can complete the above actions. For example, the vertical moving mechanism can be a telescopic cylinder, with the telescopic end of the cylinder connected to the upper pressure plate 1 and the lower pressure plate 2 to complete the pressing down and raising actions of the upper and lower pressure plates.

[0044] The rotating mechanism 7 drives the upper pressure plate 1 to rotate. Preferably, the rotating shaft of the rotating mechanism is coaxially connected to the shaft of the upper pressure plate, which is parallel to the plane of the fiber tray and perpendicular to the shaft of the membrane fibers. The specific structure of the rotating mechanism is not limited, as long as it can perform the above actions. For example, the rotating mechanism can be a pneumatic swing table.

[0045] Among them, such as Figure 6 As shown, both the upper pressure plate 1 and the lower pressure plate 2 are rectangular flat plate structures, and the material can be metal aluminum plate. One side of the upper pressure plate 1 and the lower pressure plate 2 is provided with a glue injection groove 20, and the position of the glue injection groove 20 corresponds to the position of the glue injection nozzle. The upper surface of the lower pressure plate 2 is provided with a wire arrangement groove 21 to ensure that the film filaments are evenly arranged.

[0046] Preferably, the upper pressure plate has a first cavity with a first inlet and a first outlet. The first inlet is connected to the outlet of the water cooling device via a first connecting pipe, and the first outlet is connected to the inlet of the water cooling device via a second connecting pipe. The lower pressure plate has a second cavity with a second inlet and a second outlet. The second inlet is connected to the outlet of the water cooling device via a third connecting pipe, and the second outlet is connected to the inlet of the water cooling device via a fourth connecting pipe. The water cooling device provides condensate, which enters the first and second cavities of the upper pressure plate 1 and the lower pressure plate 2 through the first and second inlets, respectively. After circulating within the plates, the condensate flows back to the water cooling device through the first and second outlets. This allows for rapid cooling of the upper and lower pressure plates, thereby rapidly cooling and setting the hot melt adhesive, shortening the demolding time of the hot melt adhesive, and improving production efficiency.

[0047] The water cooling device can be a circulating water machine or directly connected to a tap water pipe to continuously supply cooling water to the upper and lower pressure plates.

[0048] Among them, the translational glue injection nozzle 3 and the fixed glue injection nozzle 4 are both glue injection nozzles, which are existing technologies. They can be applied to any existing glue injection nozzles that can complete the glue injection action, and will not be described in detail here.

[0049] Preferably, the plateless membrane fiber injection mechanism may further include a base 10, a first horizontal moving mechanism, a first vertical moving mechanism, and a fixed injection nozzle 4 disposed on the base 10.

[0050] Preferably, the plateless membrane fiber injection mechanism may further include a frame 11, a base 10, and a second horizontal moving mechanism placed on the frame 11.

[0051] Preferably, the lower end of the frame 11 is provided with casters and a support base, which can meet the movement of the overall glue injection mechanism and meet the needs of different film filament sizes.

[0052] Example 2

[0053] like Figure 2 As shown, the plateless membrane filament injection and sheet forming device of this embodiment includes a plateless membrane filament injection mechanism, a connecting film cutting mechanism 12, a positioning and pressing mechanism 13, an automatic sheet cutting mechanism 14, and a circulating automatic filament drawing mechanism 15 arranged in sequence. The plateless membrane filament injection mechanism is the plateless membrane filament injection mechanism of Embodiment 1.

[0054] The film cutting mechanism 12 is used for longitudinal cutting of the film;

[0055] The positioning and clamping mechanism 13 is used to fix the diaphragm in the lateral direction;

[0056] Automatic cutting mechanism 14 is used to cut the film laterally;

[0057] The automatic filament drawing mechanism 15 is used to pull the diaphragm along its length.

[0058] The working process of the plateless membrane filament injection and sheet forming device in this embodiment is as follows: the arranged membrane filaments are injected and shaped by the plateless membrane filament injection mechanism and formed into sheets. Then, the hot melt adhesive connecting each small area of ​​the sheet is cut by the connecting film cutting mechanism 12. The membrane sheet is fixed by the positioning and pressing mechanism 13 in front of the automatic sheet cutting mechanism 14 to prevent it from being scattered and to facilitate the automatic sheet cutting mechanism 14 to perform transverse cutting. The automatic sheet cutting mechanism 14 cuts the membrane sheet from right to left in the width direction until the selected length of the membrane sheet is reached. The circulating automatic filament pulling mechanism 15 is located at the end and pulls the membrane filaments on the entire production line to provide pulling power for the sheet.

[0059] Preferably, there are at least two sets of plateless membrane fiber gluing mechanisms and at least two sets of automatic cutting mechanisms, and the number of plateless membrane fiber gluing mechanisms and automatic cutting mechanisms is the same; the distance between adjacent plateless membrane fiber gluing mechanisms is equal to the distance between adjacent automatic cutting mechanisms. Using two or more sets of plateless membrane fiber gluing mechanisms and automatic cutting mechanisms enables dual-station and multi-station fiber arrangement of the entire device, allowing for the simultaneous arrangement of fibers into two or more membrane sheets, achieving continuous and efficient membrane sheet production, shortening production intervals, and improving production efficiency.

[0060] The specific structure of the connecting film cutting mechanism 12 is not limited, as long as it can perform longitudinal cutting of the film; any existing connecting film cutting mechanism can be applied here. For example... Figure 3As shown, preferably, the connecting film cutting mechanism 12 includes pneumatic scissors located between adjacent sections of the film, with the cutting direction of the pneumatic scissors along the length of the film. Specifically, a film is generally divided into 2-4 sections, and 1-5 pneumatic scissors are used to reduce the distance between the films at the connection points of different sections and on the outermost side. During the drawing process, the filament feeding sheet is conveyed through the pneumatic scissors, and the hot melt adhesive connecting each section is simultaneously cut and separated.

[0061] The specific structure of the positioning and clamping mechanism 13 is not limited, as long as it can fix the diaphragm in the lateral direction. Existing positioning and clamping mechanisms are all applicable here. Preferably, as follows... Figure 4 As shown, the positioning and clamping mechanism includes a first base 131, a third vertical moving mechanism 132, a fourth vertical moving mechanism 133, a first upper pressing part 134, and a first lower pressing part 135. The third vertical moving mechanism 132 and the fourth vertical moving mechanism 133 are mounted on the first base 131. The moving end of the third vertical moving mechanism 132 is connected to the first upper pressing part 134, and the moving end of the fourth vertical moving mechanism 133 is connected to the first lower pressing part 135. After the first upper pressing part 134 and the first lower pressing part 135 are pressed together, the membrane can be clamped. After the circulating automatic drawing mechanism 15 pulls the membrane fiber to the position, the positioning and clamping mechanism 13 is activated. The third vertical moving mechanism 132 and the fourth vertical moving mechanism 133 drive the first upper pressing part 134 and the first lower pressing part 135 to press down and press up respectively, clamping the membrane.

[0062] The third vertical moving mechanism 132 and the fourth vertical moving mechanism 133 respectively drive the first upper pressing part 134 and the first lower pressing part 135 to move vertically. The specific structure of the vertical moving mechanism is not limited, as long as it can complete the above actions. For example, the vertical moving mechanism can be a telescopic cylinder, with its telescopic end connected to the first upper pressing part 134 and the first lower pressing part 135, completing the downward and upward movements of the first upper pressing part 134 and the first lower pressing part 135. Specifically, the third vertical moving mechanism 132 and the fourth vertical moving mechanism 133 each consist of four sets of cylinders, with each cylinder providing a working pressure of approximately 0.2-0.7 MPa and a total pressure of approximately 1000-2000 N.

[0063] The first upper pressing part 134 and the first lower pressing part 135 can be pressure plates.

[0064] The specific structure of the automatic cutting mechanism 14 is not limited, as long as it can perform transverse cutting of the film; any existing automatic cutting mechanism can be applied here. Preferably, as follows: Figure 4As shown, the automatic cutting mechanism 14 includes a third horizontal moving mechanism 141 and a pneumatic scissor 142. The pneumatic scissor 142 is connected to the moving end of the third horizontal moving mechanism 141, and can move along the width direction of the film under the drive of the third horizontal moving mechanism 141. The pneumatic scissor, driven by the third horizontal moving mechanism, cuts the filament sheet sequentially from right to left in the width direction.

[0065] The third horizontal moving mechanism 141 functions to move the pneumatic scissors horizontally. The specific structure of the horizontal moving mechanism is not limited, as long as it can perform the aforementioned actions. For example, the horizontal moving mechanism can be a linear module consisting of a horizontal slide rail, a slider, a lead screw and nut assembly, and a motor, where the slider moves along the horizontal slide rail under the drive of the motor.

[0066] The function of the circulating automatic fiber drawing mechanism 15 is to pull the diaphragm along its length. The specific structure of the circulating automatic fiber drawing mechanism 15 is not limited, as long as it can perform the above actions. Preferably, as shown... Figure 5 As shown, the automatic filament drawing mechanism 15 includes a fourth horizontal moving mechanism 151, a drawing frame 152, a fifth vertical moving mechanism 153, a sixth vertical moving mechanism 154, a second upper pressing part 155, and a second lower pressing part 156. The drawing frame 152 is connected to the moving end of the fourth horizontal moving mechanism 151, and the drawing frame 152 can move along the length direction of the film under the drive of the fourth horizontal moving mechanism 151. The fifth vertical moving mechanism 153 and the sixth vertical moving mechanism 154 are disposed on the drawing frame 152. The second upper pressing part 155 is connected to the moving end of the fifth vertical moving mechanism 153. The second lower pressing part 156 is connected to the moving end of the sixth vertical moving mechanism 154. After the second upper pressing part 155 and the second lower pressing part 156 are pressed together, the film can be clamped. The fifth vertical moving mechanism 153 and the sixth vertical moving mechanism 154 drive the second upper pressing part 155 and the second lower pressing part 156 to press down and press up respectively, clamping the membrane. Then, the fourth horizontal moving mechanism 151 drives the drawing frame 152 to move horizontally along the length of the membrane fiber, pulling the membrane fiber forward to complete the drawing.

[0067] The specific structures of the fifth vertical moving mechanism 153 and the sixth vertical moving mechanism 154 are not limited, as long as they can complete the aforementioned actions. For example, the vertical moving mechanism can be a telescopic cylinder, with the telescopic end of the cylinder connected to the second upper pressing part 155 and the second lower pressing part 156, completing the pressing and lifting actions of the second upper pressing part 155 and the second lower pressing part 156. Specifically, the fifth vertical moving mechanism 153 and the sixth vertical moving mechanism 154 are both cylinders, and the cylinders are evenly distributed to ensure that the clamping force is the same at each position.

[0068] Among them, the second upper pressing part 155 and the second lower pressing part 156 are pressure plates. The pressure plates are clamped with soft rubber to increase friction and avoid damage to the membrane fibers.

[0069] Preferably, the plateless film filament injection and filament arrangement sheet forming device further includes a sheet-joining and conveying mechanism 16. The sheet-joining and conveying mechanism 16 is located below the automatic cutting mechanism 14 and the circulating automatic filament drawing mechanism 15, and is used to receive the filament sheets cut by the automatic cutting mechanism 14 and convey them to the next process. The main body of the sheet-joining and conveying mechanism 16 is a conveyor belt, and it is driven by a motor to complete the conveying work. The cut filament sheets fall onto the conveyor belt of the sheet-joining and conveying mechanism 16 and are transported to the stacking area.

[0070] Preferably, the plateless membrane filament injection and sheet forming device further includes a first guide wheel 17, a second guide wheel 18, and a third guide wheel 19; the first guide wheel 17 is located behind the plateless membrane filament injection mechanism; the second guide wheel 18 is located in front of the film cutting mechanism 12; and the third guide wheel 19 is located behind the film cutting mechanism 12. The guide wheels prevent the membrane filaments from shifting left or right, ensuring stable operation of the sheet forming process.

[0071] Preferably, the plateless film filament injection and filament assembly device further includes a first base, on which the film cutting mechanism 12, the positioning and pressing mechanism 13, the automatic cutting mechanism 14, and the circulating automatic filament drawing mechanism are all located.

[0072] Preferably, the first base is also provided with a slide rail, and the bottom sides of the first base of the positioning and pressing mechanism 13 and the drawing frame of the circulating automatic drawing mechanism 15 are also provided with positioning devices. The positioning devices are right-angled metal plates, the bottom of which are slidably connected to the slide rail and can be fixed to the slide rail by fastening bolts. The positioning devices can drive the circulating drawing device and the automatic cutting device to move back and forth on the slide rail as a whole, so that the position of the device can be adjusted according to the needs to make it suitable for the production of films of different lengths.

[0073] The overall working process of this plateless membrane filament injection and sheet forming device is as follows: The arranged membrane filaments are injected and shaped by the plateless membrane filament injection mechanism, forming sheets. Next, a circulating automatic filament drawing mechanism drives the filament drawing sheet, with guide wheels preventing filament displacement. During the filament drawing process, the filament drawing sheet passes the connecting film cutting mechanism, separating the four sections of a sheet of filament film. The sheet at the plateless membrane filament injection mechanism moves to the positioning and pressing mechanism, completing one filament drawing cycle. When the circulating automatic filament drawing mechanism returns to its initial position, it enters the next round of injection. Next, the filament drawing sheet is positioned and pressed, driven by four sets of cylinders, each controlling one of the four sections of the filament drawing sheet. Next, two sets of automatic cutting mechanisms 14 operate simultaneously to cut the film at the injection position. The automatic cutting mechanism 14 is driven by a linear module to move pneumatic shears, completing the cutting. Next, the cylinders of the circulating automatic filament drawing mechanism release pressure, entering the next filament drawing cycle. After the two films are laid out, they fall onto the lamination and transfer mechanism and are transported by conveyor belt to the stacking position, completing the entire film laying process.

[0074] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
