Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter membrane technology, and specifically to a pre-flattening mechanism for filter membrane casting processing. Background Technology
[0002] Filtration membranes are a type of membrane material widely used in water treatment, food processing, and pharmaceutical manufacturing. They come in various types and have different functions. Common filtration membranes include microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, and reverse osmosis membranes. Their filtration precision ranges from a few micrometers to 0.0001 micrometers, and they can intercept impurities of different sizes in water, such as sediment, rust, bacteria, viruses, organic matter, inorganic matter, and heavy metal ions. Furthermore, based on their materials, filtration membranes can also be classified as polyethersulfone (PES) membranes, polyvinylidene fluoride (PVDF) membranes, nylon membranes, and polytetrafluoroethylene (PTFE) membranes. Each type has different properties, such as hydrophilicity, chemical corrosion resistance, and high strength, making them suitable for different applications. For example, PES membranes, due to their low protein adsorption properties, are widely used for filtration and clarification in the food and pharmaceutical industries; while PTFE membranes, due to their hydrophobicity, high temperature resistance, and corrosion resistance, are often used for filtration of chemical solvents, strong organic solvents, and acids.
[0003] Filter membranes need to be flattened during processing. Existing flattening methods usually require manual unfolding, which is time-consuming, labor-intensive, and inefficient. This is not conducive to the rapid processing and production of filter membranes and reduces the factory's efficiency.
[0004] Therefore, it is necessary to redesign and modify the filter membrane flattening device to effectively prevent the problems existing in the background technology. Utility Model Content
[0005] This invention provides a pre-flattening mechanism for the casting process of filter membranes, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0007] An embodiment of this utility model provides a pre-flattening mechanism for filter membrane casting processing, comprising: an operation box, with support feet fixedly connected to the four corners of the bottom of the operation box, an opening at the top of the operation box, a flattening mechanism at the bottom of the inner wall of the operation box, and a moving mechanism at the top of the operation box. The flattening mechanism is used to efficiently unfold the filter membrane, and the moving mechanism is used to quickly move the filter membrane.
[0008] The above technical solution, through the arrangement of the flattening mechanism and the moving mechanism, facilitates the efficient flattening of the filter membrane and the efficient moving of the filter membrane, thereby increasing the processing and production efficiency of the filter membrane and making it easier for users to operate.
[0009] Furthermore, the flattening mechanism includes a trapezoidal block, which is fixedly installed on the bottom of the inner wall of the operating box. A motor is fixedly installed on the top of the trapezoidal block, and an extension wheel is fixedly connected to the output end of the motor. A fixed seat is provided at the bottom of the extension wheel.
[0010] The above technical solution allows for easy support and fixation of the motor using trapezoidal blocks. The rotation of the motor drives the stretching wheel to rotate, which in turn causes the stretching wheel to rotate outward, thus unfolding the filter membrane outward for easier stretching.
[0011] Furthermore, the inner wall of the fixed seat is movably connected with several balls, which are used in conjunction with the stretching wheel.
[0012] The above technical solution, through the setting of the ball bearings, reduces the friction of the stretching wheel rotation, thereby improving the stability and efficiency of the stretching wheel rotation, facilitating the stretching of the filter membrane, and improving the stretching efficiency.
[0013] Furthermore, positioning grooves are provided on both sides of the stretching wheel, and positioning balls are slidably connected inside the positioning grooves. A bracket is movably installed on the outside of the positioning balls, and the bottom of the bracket is fixedly connected to the top of the fixed base.
[0014] The above technical solution, through the setting of the positioning groove, makes it easy for the positioning ball and the bracket to limit the stretching wheel, preventing the stretching wheel from shaking when rotating, and making it convenient for users to use.
[0015] Furthermore, the number of stretching wheels is six, and universal couplings are provided between the six stretching wheels, with the number of universal couplings being five.
[0016] The above technical solution, through the setting of the coupling, facilitates the efficient transmission of motor power, enabling multiple stretching wheels to rotate synchronously, thereby improving the stretching efficiency of the filter membrane, saving energy, and making it convenient for users.
[0017] Furthermore, the moving mechanism includes a rotating column, which is fixedly installed on the top of the operation box, and an electric push rod is fixedly installed on the top of the rotating column via a connecting rod.
[0018] The above technical solution, through the setting of the rotating column, facilitates the efficient movement of the filter membrane, thereby facilitating the production of the filter membrane and making it convenient for users.
[0019] Furthermore, an air pump is fixedly connected to the output end of the electric actuator, and a suction head is connected to the bottom of the air pump. The suction head is a plurality of such suction heads, which are evenly distributed in a ring.
[0020] The above technical solution, with its air pump and multiple suction heads, facilitates efficient adsorption of the filter membrane, improves the stability of the filter membrane during movement, and enhances the efficiency of stretching and production.
[0021] The above-described solution of this utility model has at least the following beneficial effects:
[0022] 1. This utility model uses a starting motor to rotate the stretching wheel. The ball bearings reduce friction during the rotation of the stretching wheel, and the positioning balls ensure efficient fixation of the stretching wheel, preventing it from shifting. The universal coupling allows multiple stretching wheels to rotate synchronously, thus ensuring that the filter membrane stretches evenly outward.
[0023] 2. In this utility model, the electric push rod moves to the bottom, which drives the air pump to move to the bottom, so that the suction head at the bottom of the air pump can efficiently adsorb the filter membrane. By rotating the rotating column, the filter membrane can be moved efficiently. Attached Figure Description

[0030] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0031] like Figures 1 to 4As shown, this utility model provides a pre-flattening mechanism 4 for filter membrane casting processing, including: an operation box 1, with support feet 2 fixedly connected to the four corners of the bottom of the operation box 1, an opening 3 on the top of the operation box 1, a flattening mechanism 4 at the bottom of the inner wall of the operation box 1, and a moving mechanism 5 at the top of the operation box 1. The flattening mechanism 4 is used to efficiently unfold the filter membrane, and the moving mechanism 5 is used to quickly move the filter membrane. The arrangement of the flattening mechanism 4 and the moving mechanism 5 facilitates efficient flattening of the filter membrane and efficient movement of the filter membrane, thereby improving the processing efficiency of the filter membrane.
[0032] like Figures 1 to 4 As shown, the flattening mechanism 4 includes a trapezoidal block 41, which is fixedly installed at the bottom of the inner wall of the operation box 1. A motor 42 is fixedly installed at the top of the trapezoidal block 41, and a stretching wheel 43 is fixedly connected to the output end of the motor 42. A fixed seat 44 is provided at the bottom of the stretching wheel 43. The trapezoidal block 41 facilitates the support and fixation of the motor 42. The rotation of the motor 42 drives the stretching wheel 43 to rotate, thereby causing the stretching wheel 43 to rotate outward and drive the filter membrane to unfold outward, facilitating the stretching process. A number of ball bearings 45 are movably connected to the surface of the inner wall of the fixed seat 44. The ball bearings 45 work in conjunction with the stretching wheel 43. The arrangement of the ball bearings 45 reduces the friction of the stretching wheel 43, thereby improving the stability and efficiency of the stretching wheel 43's rotation. The filter membrane is stretched, improving the stretching efficiency. Positioning grooves 46 are provided on both sides of the stretching wheel 43. Positioning balls 47 are slidably connected inside the positioning grooves 46, and brackets 48 are movably installed on the outside of the positioning balls 47. The bottom of the brackets 48 is fixedly connected to the top of the fixed base 44. The positioning grooves 46 allow the positioning balls 47 and brackets 48 to limit the stretching wheel 43, preventing it from shaking during rotation. There are six stretching wheels 43, and five universal couplings 49 are provided between them. The couplings facilitate efficient power transmission from the motor 42, allowing multiple stretching wheels 43 to rotate synchronously, improving the filter membrane stretching efficiency and saving energy.
[0033] In this embodiment of the utility model (working principle), during use, the user starts the motor 42, and the rotation of the motor 42 drives the stretching wheel 43 to rotate. The ball bearings 45 reduce the friction of the rotation of the stretching wheel 43. The positioning ball 47 facilitates efficient fixation of the stretching wheel 43 and prevents the stretching wheel 43 from shifting. At the same time, the universal coupling 49 facilitates the synchronous rotation of multiple stretching wheels 43, so that the filter membrane is evenly stretched outward, which is convenient for the user.
[0034] like Figures 1 to 4As shown, the moving mechanism 5 includes a rotating column 51, which is fixedly installed on the top of the operation box 1. An electric push rod 52 is fixedly installed on the top of the rotating column 51 via a connecting rod. The rotating column 51 facilitates efficient movement of the filter membrane, thereby facilitating the production of the filter membrane. An air pump 53 is fixedly connected to the output end of the electric push rod 52. A suction head 54 is connected to the bottom of the air pump 53. There are several suction heads 54, which are evenly distributed in a ring. The arrangement of the air pump 53 and multiple suction heads 54 facilitates efficient adsorption of the filter membrane, making the filter membrane more stable during movement and improving the efficiency of stretching and production.
[0035] In this embodiment of the invention, the electric push rod 52 moves to the bottom, driving the air pump 53 to move to the bottom, thereby enabling the suction head 54 at the bottom of the air pump 53 to efficiently adsorb the filter membrane. By rotating the rotating column 51, the filter membrane can be moved efficiently.
[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
