Description

Technical Field

[0001] This utility model belongs to the field of heating and leveling technology, and in particular relates to a bending-type multi-layer heating and leveling device. Background Technology

[0002] Heat-leveling of filter element plush cloth typically refers to the process of heating the plush cloth material during the production or maintenance of the filter element to improve its physical properties, such as increasing its flatness, strength, or removing excess moisture. This treatment helps ensure the filtration efficiency and durability of the filter element during use.

[0003] Traditional filter element plush cloth leveling devices generally include a feeding mechanism, a heating mechanism, and a winding mechanism. The feeding mechanism delivers the plush cloth to the heating mechanism for heating, and the winding mechanism rolls up the heated plush cloth to form a film.

[0004] In the existing technology, most heating mechanisms are box-type structures. The feeding mechanism inputs the plush fabric from the inlet of the box, and the heated and dried plush fabric moves from the outlet of the box to the winding mechanism. The box-type heating mechanism only provides a one-way movement path for the plush fabric, and the heating and drying time of the plush fabric is short, resulting in low leveling efficiency, which urgently needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a bending-type multi-layer heating and leveling device, which aims to solve the technical problem that the existing leveling devices, which use a box-type heating mechanism, only provide a single-pass movement path for the plush fabric, resulting in a short heating and drying time for the plush fabric and thus low leveling efficiency.

[0006] To achieve the above objectives, this utility model provides a bending-type multi-layer heating and leveling device, including a support frame, a bending transmission assembly, and a heating assembly. The support frame is provided with an open cavity for the input or output of the plush fabric to be leveled. The bending transmission assembly includes an input roller unit, an output roller unit, and at least two sets of bending roller units. The input roller unit and the output roller unit are respectively disposed at the input end and output end of the open cavity. All the bending roller units are evenly distributed on both sides of the inner wall of the open cavity. All the bending roller units guide the plush fabric input through the input roller unit to bend and reciprocate within the open cavity and output from the output roller unit. The heating assembly is disposed within the open cavity, with its output end facing the interior of the open cavity.

[0007] Optionally, the heating assembly includes a lifting drive source, a mounting base, and a heat transfer plate. The lifting drive source is fixedly disposed at the top of the open cavity, the mounting base is disposed at the output end of the lifting drive source, and the heat transfer plate is disposed on the mounting base. The lifting drive source can drive the mounting base to move vertically, so that the mounting base moves the heat transfer plate closer to or away from the plush cloth to be flattened.

[0008] Optionally, the lifting drive source includes at least two sets of pushers evenly spaced apart on the top and bottom walls of the open cavity, with all the pushers directed toward the interior of the open cavity, and the bending transmission assembly located between all the pushers.

[0009] Optionally, the pusher is a linear cylinder or an electric actuator.

[0010] Optionally, the number of mounting bases is equal to the number of pushing members, and all the mounting bases are respectively installed at the output end of the corresponding pushing member, and the heat transfer plate is fixedly connected to all the mounting bases.

[0011] Optionally, the support frame includes a crossbeam and a column, the column and the crossbeam being fixedly overlapped to form a square frame structure. The input roller unit is disposed on the column near the input end of the open cavity. The heating component is disposed on the crossbeam near the top and / or bottom of the open cavity. The output roller unit is disposed on the column near the output end of the open cavity. The input roller unit and the output roller unit are disposed on opposite sides of the open cavity, wherein both the input roller unit and the output roller unit are located within the heating radiation area of ​​the heating component. The input roller unit and the output roller unit have a height difference along the vertical direction. All the bending roller units are disposed between the input roller unit and the output roller unit. All the bending roller units are evenly distributed on both sides of the open cavity. All the bending roller units are alternately staggered along the vertical direction, so that the plush fabric wound on all the bending roller units can move along a Z-shaped path.

[0012] Optionally, a tensioning roller unit is provided above the input roller unit, and the outer diameter of the tensioning roller unit is smaller than that of the input roller unit.

[0013] Optionally, the output roller unit includes an extension frame, an extension plate, and an output roller shaft. The extension frame is disposed on the outer wall of the column, the extension plate is disposed on the extension frame, and the output roller shaft is rotatably connected to the end of the extension frame away from the column. The extension plate is at the same height as the topmost bending roller unit.

[0014] Optionally, an extension frame is connected to the side wall of the column near the output end of the open cavity. The extension frame covers the output roller unit, and a guide roller shaft is rotatably connected to the extension frame.

[0015] Optionally, a diaphragm conveying roller unit is rotatably connected to the extension frame, the diaphragm conveying roller unit being located below the guide roller shaft.

[0016] The bending-type multi-layer heating and leveling device provided in this utility model embodiment has at least one of the following technical effects: After the heating component raises the temperature of the open cavity, the plush fabric to be leveled is conveyed into the open cavity by the input roller unit. The plush fabric input by the input roller unit passes through all bending roller units in sequence along the Z-shaped path, forming a multi-layer movable plush fabric that is bent and filled in the open cavity, and then output by the output roller unit. Compared with the traditional plush fabric leveling device, which only uses a single-line conveying path to drive the plush fabric to move, resulting in short heating time and poor leveling effect, the bending-type multi-layer heating and leveling device provided in this utility model embodiment uses a multi-set bending roller structure to guide the plush fabric to move back and forth along the Z-shaped path in the open cavity, effectively increasing the residence time and heating area of ​​the plush fabric in the high-temperature area, effectively improving the heating efficiency of the plush fabric, and improving the leveling effect.

The following description is based on the accompanying drawings. Figures 1-2 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0029] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0032] In one embodiment of this utility model, such as Figures 1-2As shown, a cable winding device is provided, including a support frame 100, a bending transmission assembly 200, and a heating assembly 300. The support frame 100 is provided with an open cavity 400 for the input or output of a piece of plush fabric to be flattened. The bending transmission assembly 200 includes an input roller unit 210, an output roller unit 220, and at least two sets of bending roller units 230. The input roller unit 210 and the output roller unit 220 are respectively disposed at the input end and the output end of the open cavity 400. All the bending roller units 230 are evenly distributed on both sides of the inner wall of the open cavity 400. All the bending roller units 230 guide the plush fabric input through the input roller unit 210 to bend and reciprocate within the open cavity 400 and output from the output roller unit 220. The heating assembly 300 is disposed within the open cavity 400, and the output end of the heating assembly 300 faces the interior of the open cavity 400.

[0033] In this embodiment, the outer wall of the support frame 100 is provided with a heat-insulating shell structure that covers the entire open cavity 400. The bottom of the support frame 100 is also provided with a diaphragm transmission assembly. The diaphragm transmission assembly is used to transmit the diaphragm to one side of the output roller unit 220, so that the flattened plush cloth can merge with the diaphragm in time and move to the external bonding device.

[0034] Specifically, after the heating component 300 raises the temperature of the open cavity 400, the plush fabric to be leveled is conveyed into the open cavity 400 via the input roller unit 210. The plush fabric input via the input roller unit 210 passes through all the bending roller units 230 sequentially along a Z-shaped path, forming a multi-layer movable plush fabric that is bent and filled in the open cavity 400, and then output via the output roller unit 220. Compared with the traditional plush fabric leveling device, which only uses a single-line conveying path to drive the plush fabric movement, resulting in short heating time and poor leveling effect, the bending multi-layer heating leveling device provided in this embodiment of the utility model uses a multi-set bending roller structure to guide the plush fabric to move back and forth along a Z-shaped path in the open cavity 400, effectively increasing the residence time and heated area of ​​the plush fabric in the high-temperature area, effectively improving the heating efficiency of the plush fabric, and improving the leveling effect.

[0035] like Figures 1-2As shown, the heating assembly 300 further includes a lifting drive source 310, a mounting base 320, and a heat transfer plate 330. The lifting drive source 310 is fixedly disposed at the top of the open cavity 400. The mounting base 320 is disposed at the output end of the lifting drive source 310. The heat transfer plate 330 is disposed on the mounting base 320. The lifting drive source 310 can drive the mounting base 320 to move vertically, so that the mounting base 320 drives the heat transfer plate 330 to move closer to or away from the plush cloth to be flattened.

[0036] Specifically, an electric heating wire is provided at the end of the heat transfer plate 330 near the mounting base 320. The heat emitted by the electric heating wire after being energized is transferred to the heat transfer plate 330, so that the entire end face of the heat transfer plate 330 is heated evenly. The uniform heat emitted by the heat transfer plate 330 fills the entire open cavity 400 through thermal radiation, so that the plush cloth located in the open cavity 400 is fully heated.

[0037] Furthermore, the lifting drive source 310 includes at least two sets of pushing members 311 evenly spaced apart on the top and bottom walls of the open cavity 400. All pushing members 311 are positioned with their pushing direction facing the interior of the open cavity 400, and the bending transmission assembly 200 is located between all the pushing members 311. In this embodiment, there are two sets of pushing members 311, distributed along the top corner edge of the open cavity 400, with a gap between them. Synchronously driving the heat transfer plate 330 with the two sets of pushing members 311 improves the movement stability of the heat transfer plate 330. Specifically, the pushing member 311 is a linear cylinder or an electric actuator. Linear cylinders and electric actuators are technically mature structures and will not be described further in this embodiment.

[0038] like Figures 1-2 As shown, the number of mounting bases 320 is equal to the number of pushing members 311. All mounting bases 320 are respectively installed at the output end of the corresponding pushing member 311, and the heat transfer plate 330 is fixedly connected to all mounting bases 320. In this embodiment, the mounting base 320 is an insulating heat-insulating plate. Using mounting bases 320 to connect the heat transfer plate 330 helps improve the installation stability of the heat transfer plate 330 and prevents excessive heat transfer from the heat transfer plate 330 to the pushing member 311, thereby improving the service life of the pushing member 311.

[0039] like Figures 1-2As shown, the support frame 100 further includes a crossbeam 110 and a column 120, the column 120 and the crossbeam 110 being fixedly overlapped to form a square frame structure. The input roller unit 210 is disposed on the column 120 near the input end of the open cavity 400; the heating assembly 300 is disposed on the crossbeam 110 near the top and / or bottom of the open cavity 400; the output roller unit 220 is disposed on the column 120 near the output end of the open cavity 400. The input roller unit 210 and the output roller unit 220 are respectively disposed on both sides of the open cavity 400. The input roller unit 210 and the output roller unit 220 are both located within the heating radiation area of ​​the heating assembly 300. The input roller unit 210 and the output roller unit 220 have a height difference in the vertical direction. All the bending roller units 230 are disposed between the input roller unit 210 and the output roller unit 220. All the bending roller units 230 are evenly distributed on both sides of the open cavity 400. All the bending roller units 230 are alternately staggered in the vertical direction, so that the plush cloth wound on all the bending roller units 230 can move along a Z-shaped path.

[0040] In this embodiment, there are two sets of heating components 300. The two sets of heating components 300 are respectively disposed at the top and bottom of the open cavity 400. The two sets of heating components 300 can heat the corresponding end faces of the top layer plush fabric and the bottom layer plush fabric respectively. On the one hand, both end faces of the plush fabric can be heated. On the other hand, the degree of heating of the plush fabric is uniform, which can effectively improve the leveling effect.

[0041] like Figures 1-2 As shown, a tensioning roller unit 240 is further provided above the input roller unit 210, and the outer diameter of the tensioning roller unit 240 is smaller than that of the input roller unit 210. Using a small-diameter tensioning roller helps to tighten the plush fabric during its movement, preventing uneven heating of the wrinkled parts of the plush fabric during heating, which would affect the smoothing effect. Specifically, the plush fabric is first wound onto the input roller unit 210, and then bent and wound onto the tensioning roller unit 240, extending in an S-shaped path.

[0042] like Figures 1-2As shown, the output roller unit 220 further includes an extension frame 221, an extension plate 222, and an output roller shaft 223. The extension frame 221 is disposed on the outer wall of the column 120, the extension plate 222 is disposed on the extension frame 221, and the output roller shaft 223 is rotatably connected to the end of the extension frame 221 away from the column 120. The extension plate 222 is at the same height as the topmost bending roller unit 230. Specifically, the extension frame 221 is located outside the open cavity 400. After the heated plush fabric has moved a preset distance from the extension plate 222 to achieve room temperature cooling, it is then output from the output roller shaft 223. This helps to prevent the plush fabric from deforming due to bending and traction by the output roller shaft 223 at high temperature, ensuring that the plush fabric is flat and stable.

[0043] like Figures 1-2 As shown, further, an extension frame 130 is connected to the side wall of the column 120 near the output end of the open cavity 400. The extension frame 130 covers the output roller unit 220. A guide roller shaft 140 is rotatably connected to the extension frame 130. The guide roller shaft 140 and the output roller unit 220 are suspended, which is beneficial for the plush cloth to fully exchange heat with room temperature air before being output to the next station, thereby improving the cooling effect.

[0044] like Figures 1-2 As shown, a diaphragm conveying roller unit 150 is rotatably connected to the extension frame 130. The diaphragm conveying roller unit 150 is located below the guide roller shaft 140. The guide roller shaft 140 is installed by making full use of the space of the extension frame 130. On the one hand, it can improve the meeting efficiency of the plush fabric and the diaphragm. On the other hand, it is beneficial to optimize the space and reduce the manufacturing cost of the plush fabric leveling production line.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
