Description

Technical Field

[0001] This invention relates to the field of membrane production technology, specifically to a water treatment membrane preparation apparatus. Background Technology

[0002] Water treatment membranes are a type of membrane commonly used for water filtration. During the production process, they often require related water treatment membrane preparation equipment for processing and production.

[0003] For example, the existing Chinese patent publication number is CN210544426U, entitled "A Water Treatment Membrane Preparation Apparatus and its Scraper Structure." This patent includes a fixed blade holder, a movable blade holder sleeved inside the fixed blade holder, the movable blade holder being movable within the fixed blade holder, a scraper fixing device fixedly connected to the movable blade holder, one end of the scraper fixing device extending out of the fixed blade holder and fixedly connected to a scraper; the fixed blade holder is also equipped with a movable blade holder adjustment device for adjusting the position of the movable blade holder. Another water treatment membrane preparation apparatus is also disclosed, including a liquid tank, the liquid tank being equipped with a conveyor shaft, the conveyor shaft being capable of reciprocating along the axial direction, and the aforementioned scraper structure fixedly connected to the conveyor shaft.

[0004] In the production process of existing water treatment membranes, such as RO cylindrical membranes, the structure is a multi-layer composite structure, with each layer bonded together by an adhesive. Before winding, an adhesive strip needs to be applied between each membrane layer. The current specific operation is as follows: first, the first membrane layer is placed, then adhesive is applied to the first membrane layer, then the second membrane layer is placed and adhered on the first membrane layer, and then the above steps are repeated. After applying adhesive to the surface of the second membrane layer, the third membrane layer is then placed on top of the second membrane layer. However, the disadvantage of this method is that the covering of each membrane layer and the application of adhesive cannot be carried out simultaneously, which affects the work efficiency.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Please see Figure 1-9 The present invention provides a water treatment membrane preparation apparatus, including a machine base 1, on which a feeding mechanism 2 for transferring membrane sheets is installed. The feeding mechanism 2 includes:

[0036] The diaphragm support plate assembly 3 includes a support plate 3.1, which is capable of reciprocating between a loading position and a unloading position on the machine 1. The front side of the support plate 3.1 is used to support the diaphragm.

[0037] The adhesive spraying assembly 4 is installed on the back of the support plate 3.1;

[0038] The material positioning component 5 can position the diaphragm on the diaphragm tray assembly 3 on the machine base 1;

[0039] During the process of the support plate entering the feeding position, the glue spraying assembly is used to spray glue onto the diaphragm below the support plate 3.1.

[0040] Specifically, the shortcomings of the existing technology are that the covering and adhesive application of each diaphragm cannot be carried out simultaneously, which affects work efficiency. However, by having the diaphragm support plate assembly 3 move back and forth on the machine 1, and with the cooperation of the glue spraying assembly 4 and the material setting assembly 5, the covering and adhesive application steps of each diaphragm during processing can be carried out simultaneously, thereby improving work efficiency.

[0041] Specifically, a winding roller device for winding the film is installed at the feeding position of machine 1. The film support plate assembly 3 moves the film from the feeding position to the feeding position end where the winding roller device is located, thereby facilitating the winding roller device to wind up multiple stacked and bonded film sheets. The feeding position and the feeding position are on the same horizontal plane at the top of machine 1. The plate body of the support plate 3.1 is parallel to the feeding position and the feeding position, and the support plate 3.1 is located above the feeding position and the feeding position. When the support plate 3.1 moves parallel from above the feeding position to above the feeding position, the fixed material group... Component 5 limits and fixes the film carried on the upper part of the support plate 3.1. When the support plate 3.1 moves from the feeding position to the feeding position, the film carried on the upper part of the support plate 3.1 separates from the support plate 3.1 under the action of the fixing component 5, so that the film falls and covers the feeding position. When the support plate 3.1 completely reaches the feeding position, the film is completely separated from the support plate 3.1. At this time, the fixing component 5 is released from limiting and fixing the film, so that the film falls completely into the feeding position area. The fixing component 5 can be selected as being installed on the machine base 1. The electric gripper's clamping part is at the same plane height as the support plate 3.1. When the support plate 3.1 moves the diaphragm to the clamping area of ​​the electric gripper, the sensor on the electric gripper receives a signal, causing the electric gripper to clamp and fix the diaphragm on the support plate 3.1. During the process of the support plate 3.1 moving from above the feeding position to the unloading position, when one end of the support plate 3.1 coincides with the vertical direction of the unloading position, the adhesive spraying assembly 4 sprays the relevant adhesive onto the unloading position. The adhesive spraying assembly 4 moves with the support plate 3.1, thereby applying adhesive to the unloading position. The adhesive spraying trajectory is formed to facilitate the subsequent covering and bonding of the film. The adhesive spraying component 4 can be an inductive adhesive spray gun. When the inductive adhesive spray gun moves to the required adhesive spraying position with the support plate 3.1, the inductive adhesive spray gun and its compatible sensor will match the signal. The specific signal matching method can be that the sliding contact on the inductive adhesive spray gun contacts the contact part at that position, or the inductive switch on the inductive adhesive spray gun enters the signal receiving range. The inductive switch causes the inductive adhesive spray gun to run, thereby causing the inductive adhesive spray gun to spray the adhesive in the gun body to the corresponding position.

[0042] In practical use, the membrane to be laid is first laid flat on the support plate 3.1 of the membrane support plate assembly 3. Then, when the support plate 3.1 moves the membrane parallel from above the feeding position to above the unloading position, the fixing component restricts the membrane on the support plate 3.1. At the same time, during the movement of the support plate 3.1, the adhesive spraying component 4 sprays adhesive along with the support plate 3.1, so that the upper surface of the membrane below the support plate 3.1 is covered with adhesive. When the support plate 3.1 returns to the initial position, the membrane above the support plate 3.1 is covered by the membrane with adhesive on its upper surface under the action of gravity. This achieves the effect of overlapping and covering the membranes while applying adhesive between the membranes, allowing the two processes to be carried out simultaneously, saving time and improving the efficiency of water treatment membrane preparation and production.

[0043] As a preferred technical solution in this embodiment, the diaphragm support plate assembly 3 includes a driving assembly 3.2 for driving the support plate 3.1 to move, thereby driving the support plate 3.1 to move horizontally, so that the support plate 3.1 can reciprocate between the loading position and the unloading position of the machine 1. The driving assembly 3.2 includes two lead screws 3.21 located below the support plate 3.1, the two lead screws 3.21 being parallel to each other and located on the support plate 3.1 respectively. Directly below the edge, the lead screw 3.21 is parallel to the length direction of the support plate 3.1. Support columns 3.22, which are fixed to the support plate 3.1, are engaged on the lead screw 3.21. There are four support columns 3.22, located near the four corners of the support plate 3.1. A protective housing is fitted to the outer side of the lead screw 3.21. Specifically, the lead screw 3.21 spirally passes through the side of the support column 3.22, and two support columns spirally pass through the lead screw 3.21. The bottom end of column 3.22 is movably mounted with a caster 3.23 that contacts the machine base 1. The top of column 3.22 is fixed to the fabric support plate 3.1. One end of lead screw 3.21 is fixed with a stepper motor 3.24, and the other end of lead screw 3.21 is rotatably connected to a pad. The pad keeps lead screw 3.21 parallel to fabric support plate 3.1, and allows lead screw 3.21 to rotate axially under the drive of stepper motor 3.24. The power output shaft of stepper motor 3.24... Fixed to the end of the lead screw 3.21, in actual use, when the stepper motor 3.24 drives the lead screw 3.21 to rotate, the support column 3.22 drives the support plate 3.1 to move along the axial direction of the lead screw 3.21. It should be noted that the stepper motors 3.24 used to drive the lead screw 3.21 to rotate are all controlled by the same controller, such as the speed, time and direction of rotation of the stepper motors 3.24, so as to ensure that the rotation state of the lead screw 3.21 remains consistent.

[0044] As a preferred technical solution in this embodiment, the glue spraying assembly 4 includes an electric glue gun 4.1 fixed to the diaphragm support plate assembly 3. Specifically, the electric glue gun 4.1 is fixed to the bottom of the support plate 3.1, and there are at least two electric glue guns 4.1. Both electric glue guns 4.1 are close to the end of the support plate 3.1, which is the end of the support plate 3.1 facing the material feeding position. The switch part 4.2 of the electric glue gun 4.1 is provided with a trigger plate 4.3 for triggering the switch part 4.2. When the switch part 4.2 is a spring reset switch, it has two states. When the spring reset switch is in a spring-loaded state, the spring reset switch is in a spring-loaded state. When the spring reset switch button is in the pressed state, such as when a button is pressed, the switch part 4.2 is in the closed state. When the spring reset switch button is in the unpressed state, the switch part 4.2 is in the open state. When the switch part 4.2 is in the closed state, the electric glue gun 4.1 can operate normally and spray the adhesive from the electric glue gun 4.1. When the switch part 4.2 is in the open state, the adhesive from the electric glue gun 4.1 stops spraying. There are two trigger plates 4.3, which are set in parallel. On both sides of the support plate 3.1, the trigger plate 4.3 is a rigid plate. The width direction of the trigger plate 4.3 is on the same plane as the running trajectory of the switch part 4.2 as it moves with the support plate 3.1. The edge of the trigger plate 4.3 is a bevel, which facilitates the sliding of the button on the switch part 4.2 to the side of the trigger plate 4.3. When the trigger plate 4.3 contacts and presses against the button on the switch part 4.2, the switch part 4.2 is in an open circuit state. Conversely, when the trigger plate 4.3 separates from the button on the switch part 4.2, the switch part 4.2 is in a closed circuit state. It should be noted that the bottom of the trigger plate 4.3 is fixed perpendicularly to the machine base 1. The specific fixing method can be clamping, such as a vise clamp, so that the position of the trigger plate 4.3 can be changed according to actual needs. Specifically, the position is along the direction of reciprocating movement of the support plate 3.1, so that the spraying range of the electric glue gun 4.1 when spraying adhesive can be changed according to actual needs. The inclined end is on both sides of the trigger plate 4.3. In actual use, the side of the trigger plate 4.3 adjacent to the material feeding position is the position where the electric glue gun 4.1 starts spraying adhesive.

[0045] As a preferred technical solution in this embodiment, the nozzle end of the adhesive spraying assembly 4 is fitted with an extension tube 4.4. An insertion port 4.5 is provided on one side of the extension tube 4.4. A sealing post 4.6 is inserted into the insertion port 4.5. One end of the sealing post 4.6 extends out of the extension tube 4.4 and is elastically connected to the extension tube 4.4. The sealing post 4.6 and the bottom end of the insertion port 4.5 are connected by a traction wire 4.9. Preferably, a protruding ring 4.7 is fixed to the outside of the sealing post 4.6. The extension tube 4.4 is connected to the sealing post 4.6 via a spring 4.8. The spring 4.8 is movably sleeved on the outside of the sealing post 4.6. The trigger plate 4.3 can exert a squeezing effect on the sealing post 4.6. The discharge end of the electric glue gun 4.1 on the glue spraying assembly 4 is sleeved with the extension tube 4.4. The extension tube 4.4 has an open state and a closed state. When the extension tube 4.4 is in the closed state, the adhesive inside the electric glue gun 4.1 cannot flow out. When the extension tube 4.4 is in the open state, the adhesive inside the electric glue gun 4.1 flows out. The sealant flows out. In actual use, when the sealing post 4.6 contacts the trigger plate 4.3, the end of the sealing post 4.6 contacts the bottom end of the insertion interface 4.5. At this time, the extension tube 4.4 is in a sealed state by the sealing post 4.6, i.e., the extension tube 4.4 is in a sealed state. At this time, the spring 4.8 is in a compressed state. When the sealing post 4.6 separates from the trigger plate 4.3, the elastic action of the spring 4.8 causes the sealing post 4.6 to shift. At this time, the sealing post 4.6 does not... Next, the extension tube 4.4 is sealed, that is, the end of the insertion end of the sealing post 4.6 is flush with the inner wall of the extension tube 4.4, and at the same time, the axis of the sealing post 4.6 is no longer perpendicular to the axis of the extension tube 4.4, that is, the extension tube 4.4 is in the open state. It should be noted that the sealing post 4.6 and the switch part 4.2 are on the same vertical line, that is, the sealing post 4.6 and the switch part 4.2 will simultaneously contact the trigger plate 4.3, or the sealing post 4.6 and the switch part 4.2 will simultaneously separate from the trigger plate 4.3.

[0046] As a preferred technical solution in this embodiment, the material fixing component 5 includes a support frame 5.1 fixed to the machine base 1. The support frame 5.1 is a rectangular frame, and the frame part of the support frame 5.1 that serves as a support is perpendicular to the machine base 1. A straight rod motor 5.2 perpendicular to the fabric support plate 3.1 is fixed to the top of the support frame 5.1. A crossbar 5.3 is installed on the output shaft of the straight rod motor 5.2. The two ends of the crossbar 5.3 are slidably engaged with the two sides of the support frame 5.1 to ensure the stability of the lifting and lowering of the crossbar 5.3. The moving trajectory of the crossbar 5.3 is perpendicular to the reciprocating moving direction of the fabric support plate 3.1, and the crossbar 5.3 is located on the fabric support plate 3. Above 1, a protruding nail 5.4 that contacts the membrane is installed on the crossbar 5.3. In actual use, when the support plate 3.1 moves to the maximum position of the feeding position, the crossbar 5.3 moves vertically toward the support plate 3.1 under the action of the straight rod motor 5.2, and is squeezed against the membrane by the protruding nail 5.4 on the crossbar 5.3. At this time, the support plate 3.1 begins to reset, and the membrane on the support plate 3.1 remains relatively stationary with respect to the crossbar 5.3 under the insertion and limiting action of the protruding nail 5.4. The support plate 3.1 is pulled away from the bottom of the membrane, and then the membrane falls onto the feeding area on the machine 1 under the action of gravity.

[0047] As a preferred technical solution in this embodiment, the top of the support plate 3.1 is provided with a knife holder 3.15 fixed to the machine base 1. The knife holder 3.15 is a rectangular frame, and a movable sliding cutter 3.11 is mounted on the top of the knife holder 3.15. The moving trajectory line of the sliding cutter 3.11 is perpendicular to the length direction of the support plate 3.1, and the blade body of the sliding cutter 3.11 points vertically downward. The sliding cutter 3.11 is connected to the knife holder 3.15 through a screw drive mechanism. Specifically, the sliding cutter 3.1... A solid block for threaded transmission with the screw is fixed to the top of 1. When the motor drives the screw to rotate, the sliding cutter 3.11 moves synchronously with the solid block. The sliding cutter 3.11 can be used to cut the film on the support plate 3.1, causing the film to break. Thus, the sliding cutter 3.11 can cut the film on the support plate 3.1. It should be noted that the position of the cutter holder 3.15 on the machine 1 is at the midpoint between the feeding position and the loading position.

[0048] As a preferred technical solution in this embodiment, an extension plate 3.12 is installed on one end of the support plate 3.1 near the material setting component 5. An opening slot 3.13 is provided on the side of the extension plate 3.12 near the material setting component 5. There are multiple opening slots 3.13. When the support plate 3.1 moves to the maximum position of the material feeding position, the extension plate 3.12 is located directly below the crossbar 5.3. At this time, the crossbar 5.3 applies pressure to the extension plate 3.12, and the protruding nail 5.4 is inserted into the opening slot 3.13 accordingly. This helps to increase the insertion depth of the protruding nail 5.4 into the diaphragm, making it easier for the diaphragm to detach from the support plate 3.1.

[0049] As a preferred technical solution in this embodiment, the side of the extension plate 3.12 away from the opening slot 3.13 is hinged to the support plate 3.1. The support plate 3.1 and the extension plate 3.12 are connected by a hinge shaft, and the extension plate 3.12 and the support plate 3.1 are reset connected by a torsion spring 3.14. When the extension plate 3.12 is subjected to excessive pressure from the crossbar 5.3, the extension plate 3.12 deflects around the end of the support plate 3.1, thereby preventing the diaphragm from being damaged due to excessive pressure and playing a buffering role in relieving overload pressure. When the pressure of the extension plate 3.12 in the vertical direction is removed, this... When the extension plate 3.12 returns to its initial position under the elastic recovery action of the torsion spring 3.14, that is, the extension plate 3.12 and the top of the support plate 3.1 remain on the same horizontal plane. The specific hinge connection between the extension plate 3.12 and the support plate 3.1 can also be as follows: a hinge seat 3.141 is fixed to one end of the support plate 3.1 near the extension plate 3.12, an extension block 3.142 is fixed on the hinge seat 3.141, and a fixing block 3.143 is provided on one side of the extension block 3.142 and fixed to the extension plate 3.12. The fixing block 3.143 and the extension block 3.142 are connected by a tension spring 3.144.

[0050] As a preferred technical solution in this embodiment, the bottom of the extension plate 3.12 is provided with a support plate 3.121. The support plate 3.121 can keep the extension plate 3.12 and the support plate 3.1 in a flush state. The top of the support plate 3.121 is rotatably mounted with a support wheel, thereby reducing the frictional resistance between the bottom of the support plate 3.1 and the top of the support plate 3.121. It should be noted that the support plate 3.121 and the knife holder 3.15 are on the same vertical plane. The edge of the support plate 3.121 near the material feeding position is flush with the edge of the trigger plate 4.3 near the material feeding position. When the sliding cutter 3.11 cuts the film, the support plate 3.121 supports the extension plate 3.12, preventing the extension plate 3.12 from deflecting, which is conducive to the sliding cutter 3.11 achieving a good cutting effect on the film.

[0051] As a preferred technical solution in this embodiment, the top of the extension plate 3.12 is provided with a straight groove 3.122, which coincides with the trajectory line of the sliding cutter 3.11 when cutting the film. This helps to increase the cutting depth of the sliding cutter 3.11 when cutting the film during the cutting process. Multiple rows of nails 3.123 are fixed on the groove wall of the straight groove 3.122, with the tips of the nails pointing towards the feeding position. In actual use, a portion of the end of the cut film is hooked with the multiple rows of nails 3.123 fixed on the groove wall of the straight groove 3.122, which facilitates the horizontal pulling of the film by the support plate 3.1, thus promoting synchronous movement between the support plate 3.1 and the film.

[0052] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
