Description

Technical Field

[0001] The invention relates to the field of filter mesh cloth production equipment, in particular to filter mesh cloth manufacturing equipment. Background Art

[0002] Most of the current filter mesh cloths are made through a series of processes, namely twisting, warping, heald weaving, patching and shaping. The core of the traditional filter cloth production process is to weave the yarn into a finished product through a series of processes, that is, the main process is weaving. In the existing filter mesh cloth production, some manufacturers also use PP or PE lines to interweave similar yarns for filter mesh cloths such as PP or PE. The process is relatively complicated, and the equipment and methods involved in the weaving process are relatively difficult to master. The actual woven mesh aperture is not consistent in size, and there is a large gap. Of course, as a general filter cloth, the uniform distribution of the mesh aperture is not very high, but the formed mesh aperture is preferably relatively stable. However, the mesh aperture processed by weaving technology is often movable and changeable. The mesh aperture is affected by the active interweaving structure of the warp and weft lines, and accordingly cannot maintain a stable aperture. When used, the mesh aperture is easily expanded accidentally due to local blockage, affecting the stability of the filtration. At the same time, as mentioned above, because the woven filter cloth involves more equipment and labor, the production cost is actually relatively high. Especially for PP and PE materials, it is also an inevitable process to prepare the corresponding warp and weft lines in advance, and the production difficulty and cost are also relatively high. Summary of the Invention

[0003] The object of the present invention is to provide a filter mesh manufacturing device, which produces the filter mesh by directly punching out the mesh holes with a cold fluid, with a simple process, high efficiency and easier cost control.

[0004] To achieve the above-mentioned object, the filter mesh manufacturing equipment used in the present invention includes a conveying component for conveying fluid, a first cooling component, a mesh forming component, a pace control component, and a second cooling component. The conveying component conveys the fluid to the first cooling component for cooling to a set temperature. The mesh forming component has a transition cavity therein, which is a strip-shaped rectangular cavity.

[0005] The cooled fluid in the first cooling component flows into the transition cavity of the mesh forming component. The conveying component is connected to the pace control component so that every time a rated time passes, the mesh forming component punches the cooling fluid flowing through the transition cavity. The second cooling component is connected to the transition cavity so that the filter mesh cloth formed after punching is finally cooled and hardened into shape in the second cooling component.

[0006] Specifically, the conveying component includes a cache tank standing on the ground, in which a bearing plug is installed in a vertical sliding manner. When the bearing plug moves upward, the fluid is injected into the first cooling component at the upper port of the cache tank.

[0007] Furthermore, a flow plate is provided on each side of the left and right sides of the upper port of the cache tank, and the bottom ends of the two flow plates are elastically damped and hingedly arranged at the end edge of the upper port, and are arranged in an eight-shaped position relative to each other; a baffle is fixedly connected to the front and rear sides of the upper port to form an isosceles trapezoidal trumpet-shaped cover structure with the two flow plates, and the cover structure is connected to the first cooling component.

[0008] Furthermore, one side of the bottom end of the flow-gathering plate is hinged to the upper port, and a V-shaped spring plate is provided between the bottom end surface of the flow-gathering plate and the end surface of the upper port. One side of the spring plate is fixed to the end surface of the upper port, and the other side thereof is in contact with the bottom end surface of the flow-gathering plate.

[0009] Furthermore, the bottom inlet end of the first cooling component is supported by the top end of the flow-gathering plate and is located inside between the two baffles. The baffle is in dynamic sealing contact with the outer wall of the bottom inlet end, and the flow-gathering plate is in dynamic sealing contact with the end face of the bottom inlet end, so that when the two flow-gathering plates are opened / contracted by fluids of different pressures, the first cooling component can be driven to move up / down adaptively, and the first cooling component is connected to the mesh forming component by a telescopic pipe.

[0010] Preferably, the mesh forming component also includes a core block embedded and fixed in the transition cavity, and a plurality of mold rods are provided in the core block in a sliding manner. The ends of all the mold rods are fixed to a driving plate, and the driving plate and the core block are connected by a reset spring. Under normal circumstances, the reset spring prevents all the mold rods from extending into the transition cavity. Only when the driving plate is squeezed, all the mold rods are synchronously inserted into the transition cavity to punch out the mesh holes of the filter cloth.

[0011] Furthermore, the pace control component includes a rack arranged for vertical sliding, as well as a driven gear, a driven wheel, a switch, an electromagnet and a magnet embedded in the driving plate, wherein the rack is fixed to the bearing plug, the rack is engaged with the driven gear, the driven gear is coaxially fixed to the driven wheel, and a touch rod is radially fixed to the driven wheel, and each time the driven wheel rotates one circle, the touch rod touches and presses the switch once, so that the electromagnet is instantly energized once to repel and squeeze the driving plate embedded with the magnet.

[0012] Furthermore, the switch includes a tube sleeve, an electrode, a metal sliding shaft, a pressure spring, and a metal sliding column. One end of the metal sliding shaft is an arc surface, and the other end is slidably installed in the tube sleeve and supported by the pressure spring located in the tube sleeve, so that the metal sliding column, which is coaxially fixed to the metal sliding shaft, remains separated from the electrode.

[0013] The filter mesh cloth manufacturing equipment of the present invention does not need to use the production of "yarn" of the corresponding material when processing some filter mesh cloths made of plastic materials, and does not need to go through a series of complicated weaving processes. It can be directly made by stamping and forming. It is automatically stamped and formed once at regular intervals to obtain continuous filter mesh cloth. The filter mesh cloth after cooling and shaping has a simple process, high efficiency, and easier cost control. In addition, the mesh structure of the processed mesh cloth is more stable because it is integrally formed and will not change due to the interweaving and displacement of traditional yarns.

DETAILED DESCRIPTION

[0021] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0022] See also Figure 1 As shown, the filter mesh manufacturing equipment in this embodiment primarily comprises a fluid conveying component 1, a first cooling component 2, a mesh forming component 3, a pace control component 5, and a second cooling component 4. The conveying component 1, which can be a piping system, a piston cylinder, or the like, is capable of conveying the PP or PE material fluid used to make the filter mesh directly into the first cooling component 2, where it is rapidly cooled to a set temperature. At this point, the fluid's fluidity deteriorates, its flow rate slows, and its viscosity increases, resulting in a slightly melted and hardened state, allowing it to enter the transition chamber 301 within the mesh forming component 3 for subsequent punching of mesh holes. Typically, depending on the shape of the filter mesh, the transition chamber 301 is a strip-shaped rectangular cavity, i.e., an extremely thin plate-like structure with a thickness approximately equal to that of the filter mesh. Specifically, when the fluid cooled in the first cooling component 2 flows into the transition chamber 301 of the mesh forming component 3, the fluid has already reached the semi-solid state required for punching into a mesh structure. At this point, the punched mesh holes are unlikely to re-melt and close due to the flow of the fluid. At the same time, in this embodiment, since the conveying component 1 is connected to a pace control component 5, the mesh forming component 3 can punch the cooling fluid flowing through the transition cavity 301 once every rated time, that is, Figure 1 As shown, after the fluid is injected upward into the transition cavity 301 of the mesh forming component 3, the mesh forming component 3 is quickly punched once, and then the punched mesh filter cloth semi-finished product moves forward due to the continued influx of the fluid, and makes room for subsequent fluid to enter. The filter portion of the semi-finished product then enters the second cooling component 4 connected to the transition cavity 301, preferably directly connected, for extreme cooling and thorough solidification, so that the filter cloth formed after punching is finally cooled and hardened into shape in the second cooling component 4, and the next punching of the mesh forming component 3 is carried out just when the semi-finished filter cloth completely leaves the transition cavity 301, so as to obtain a series of continuous, uniform or uneven meshes.

[0023] As a specific implementation structure, such as Figure 1 The conveying component 1 includes a buffer tank 101 standing on the ground, and a bearing plug 102 is installed in the buffer tank 101 in a vertical sliding manner. When the bearing plug 102 moves upward, the fluid is injected into the first cooling component 2 at the upper port of the buffer tank 101, thereby realizing the conveying of the fluid. More specifically, as Figure 2A baffle 105 is fixedly connected to each other on the front and back sides of the upper port of the cache tank 101 to form a closed isosceles trapezoidal trumpet-shaped cover structure with the two baffles 103 to transport the fluid out, and the cover structure can be connected to the first cooling component 2.

[0024] like Figure 2 As shown, one side of the bottom end of the flow-gathering plate 103 in this embodiment is hinged to the upper port, and a V-shaped spring plate 104 is provided between the bottom end surface of the flow-gathering plate 103 and the end surface of the upper port. One side of the spring plate 104 is fixed to the end surface of the upper port, and the other side thereof is in contact with the bottom end surface of the flow-gathering plate 103 to realize elastic damping hinge.

[0025] During manufacturing, the bottom inlet end of the first cooling component 2 in this embodiment can also be a rectangular tubular structure, which is supported by the top end of the flow-gathering plate 103, which is equivalent to the inlet end of the first cooling component 2 being set on the flow-gathering plate 103. At the same time, this inlet end must also be located inside between the two baffles 105, and the baffle 105 is in dynamic sealing contact with the outer wall of the bottom inlet end, and the flow-gathering plate 103 is in dynamic sealing contact with the end face of the bottom inlet end, so that when the two flow-gathering plates 103 are opened / contracted by fluids of different pressures, they can drive the first cooling component 2 to move up / down adaptively, and the first cooling component 2 and the mesh forming component 3 are connected by a telescopic pipe, which can flexibly respond to changes in fluid flow rate and flow rate. The reliable connection of the entire fluid delivery system provides a prerequisite for flexible adjustment of the fluid input amount to adapt to the stamping and forming of the filter cloth.

[0026] More specifically, if Figure 1 The mesh forming component 3 also includes a core block 302 embedded and fixed in the transition cavity 301. A plurality of mold rods 304 are slidably fitted in the core block 302. The mold rods 304 can be arranged horizontally and parallel to each other. The ends of all mold rods 304 are fixed to a driving plate 305. The driving plate 305 is arranged vertically, and the driving plate 305 and the core block 302 are connected by a return spring 303. Under normal circumstances, the return spring 303 presses against the driving plate 305, so that all mold rods 304 cannot extend into the transition cavity 301. Only when the driving plate 305 is squeezed, all mold rods 304 are synchronously inserted into the transition cavity 301 to punch out the mesh holes of the filter cloth.

[0027] As another preferred structural design, Figure 1 and Figure 3The step control component 5 includes a rack 501 that is vertically slidable, as well as a driven gear 502, a driven wheel 503, a switch 505, an electromagnet (not shown in the figure) and a magnet (not shown in the figure) embedded in the drive plate 305. The electromagnet and the magnetic pole can be installed adaptively. Among them, the rack 501 is fixed to the bearing plug 102, and moves up and down synchronously in an integrated manner. The rack 501 is engaged with the driven gear 502, and the driven gear 502 is coaxially fixed to the driven wheel 503. A contact rod 504 is radially fixed to the driven wheel 503. Every time the driven wheel 503 rotates one circle, the contact rod 504 touches and presses the switch 505 once, so that the electromagnet is instantly energized once, and then repels and squeezes the drive plate 305 embedded with the magnet, achieving one-time stamping and forming to obtain a grid hole system of the filter cloth. For the switch 505, this embodiment recommends the following design: Figure 4 The switch 505 includes a sleeve 5051, an electrode 5055, a metal sliding shaft 5052, a pressure spring 5053, and a metal sliding column 5054. The electrode 5055 and the metal sliding column 5054 are respectively connected to the two ends of a power line. When they touch each other, the power line is connected. When manufacturing, it is best to have one end of the metal sliding shaft 5052 be an arc surface so that it can gradually contact and cooperate with the contact rod 504, and the other end is installed in the sleeve 5051 in a sliding manner and supported by the pressure spring 5053 located in the sleeve 5051. In this way, under normal circumstances, the metal sliding column 5054, which is coaxially fixed to the metal sliding shaft 5052, remains separated from the electrode 5055, and the switch 505 is always open. Figure 5 As shown, when the metal sliding column 5054 contacts the electrode 5055, the switch 505 is closed, and the metal sliding shaft 5052 is designed as an arc-shaped end face, so that the touch rod 504 can only be extended at the highest point of the arc-shaped end face, squeezing the metal sliding column 5054 to contact the electrode 5055, achieving instantaneous power-on, and the electromagnet instantly pushes the drive plate 305 to move.

Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
