Description

Technical Field

[0001] This utility model belongs to the field of filter manufacturing technology, specifically relating to a folding mechanism for air filter manufacturing. Background Technology

[0002] Air filters are air filtration devices, generally used in cleanrooms, clean factories, laboratories, and clean rooms, or for dust prevention in electronic, mechanical, and communication equipment. There are five types: pre-filters, medium-efficiency filters, high-medium efficiency filters, sub-high efficiency filters, and high-efficiency filters. Each type has different standards and performance levels.

[0003] In existing air filter folding and forming devices, when tension rollers are used to convey the aluminum foil required for filter element production, if there are impurities remaining on the aluminum foil, the impurities are easily squeezed during the folding process of the tension rollers and subsequent upper and lower corrugated rollers, leaving indentations or even causing damage to the aluminum foil, affecting its subsequent use. Furthermore, the folded aluminum foil is cut with a cutter, and the cut aluminum foil is easily dropped into the surrounding environment, causing contamination. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a folding mechanism for air filter production, featuring cleaning, impurity removal, and storage capabilities.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a folding mechanism for air filter production, comprising a folding mechanism, a tensioning mechanism on one side of the folding mechanism, a cutting mechanism on the other side of the folding mechanism, a cleaning component on the side of the tensioning mechanism away from the folding mechanism, and a collecting component on the side of the cutting mechanism away from the folding mechanism.

[0006] Preferably, the cleaning assembly includes a cleaning frame, limiting members, a fixing plate, a vacuum cleaner, a vacuum pipe, a cavity, and vacuum ports. The cleaning frame is fixedly connected to the side of the tensioning mechanism away from the folding mechanism. The fixing plate is fixedly connected to the side wall of the cleaning frame. The vacuum cleaner is fixedly connected above the fixing plate. The vacuum pipe is fixedly connected between the cleaning frame and the vacuum cleaner. A cavity is formed on the inner side wall of the cleaning frame. Several vacuum ports are formed on the side wall of the cavity. Limiting members are provided on both sides of the interior of the cleaning frame.

[0007] Preferably, the limiting component includes a mounting frame, a mesh plate, an end plate, a bidirectional screw, a threaded sleeve, and a rotating handle. The mounting frame is slidably connected to both sides of the cleaning frame. The mesh plate is fixedly connected to the inside of the mounting frame. The threaded sleeve is fixedly connected to the side wall of the mounting frame. The end plates are fixedly connected to both ends of one side of the cleaning frame. The bidirectional screw is rotatably connected between the two end plates. A rotating handle is fixedly connected to one end of the bidirectional screw.

[0008] Preferably, a guide block is fixedly connected to the end of the cleaning frame away from the end plate, a guide post is fixedly connected between the two guide blocks, and a sleeve plate is fixedly connected to the end of the mounting frame away from the threaded sleeve and located outside the guide post.

[0009] Preferably, the collection assembly includes a collection box and an L-shaped rod. The collection box is provided on the side of the cutting mechanism away from the folding mechanism, and an L-shaped rod is fixedly connected to both ends of the side wall of the cutting mechanism on one side of the collection box.

[0010] Preferably, the collection assembly further includes a side rod, a fixing screw, and a fixing hole. The side rod is fixedly connected to the side wall of the collection box above the L-shaped rod. The fixing screw is threaded inside the side rod. A fixing hole is provided inside the L-shaped rod at the position corresponding to the fixing screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model features a cleaning component. By holding the handle, the bidirectional screw rotates, causing the threaded sleeves to move in opposite directions. The movement of the threaded sleeves then moves the mounting frame. The vacuum cleaner is then activated, and one end of the aluminum foil is passed through the cleaning frame. During the insertion of the aluminum foil, the vacuum cleaner removes any remaining debris from the foil through the holes in the mesh and the suction port into the cavity. The debris then enters the dustbin on the vacuum cleaner via the suction pipe for collection. This facilitates cleaning and removing impurities from the aluminum foil surface, preventing indentations or damage caused by the pressure of debris during subsequent stretching and folding.

[0013] 2. This utility model is equipped with a collection component. The collection box is moved to the lower end of the cutting mechanism and made to fit against the side wall of the L-shaped rod. The operator rotates the fixing screw, which moves along the side rod. When the fixing screw is inserted into the fixing hole, the rotation of the fixing screw is stopped. The fixing screw can be used to fix the side rod and the L-shaped rod to ensure the stability of the collection box. After the folded aluminum foil is cut by the cutting mechanism, the cut aluminum foil falls into the collection box for collection, which is convenient for storing and placing the folded aluminum foil.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1-4 The present invention provides the following technical solution: a folding mechanism for air filter production, including a folding mechanism 1, a tensioning mechanism 5 on one side of the folding mechanism 1, a cutting mechanism 2 on the other side of the folding mechanism 1, a cleaning component 4 on the side of the tensioning mechanism 5 away from the folding mechanism 1, and a collecting component 3 on the side of the cutting mechanism 2 away from the folding mechanism 1.

[0022] Specifically, the cleaning component 4 includes a cleaning frame 41, limiting members 42, a fixing plate 43, a vacuum cleaner 44, a vacuum pipe 45, a cavity 46, and vacuum ports 47. The cleaning frame 41 is fixedly connected to the side of the tensioning mechanism 5 away from the folding mechanism 1. The fixing plate 43 is fixedly connected to the side wall of the cleaning frame 41. The vacuum cleaner 44 is fixedly connected above the fixing plate 43. The vacuum pipe 45 is fixedly connected between the cleaning frame 41 and the vacuum cleaner 44. A cavity 46 is opened on the inner side wall of the cleaning frame 41. Several vacuum ports 47 are opened on the side wall of the cavity 46. Limiting members 42 are provided on both sides of the interior of the cleaning frame 41.

[0023] By adopting the above technical solution, the distance between the two limiting members 42 is adjusted according to the thickness of the aluminum foil. Then, the vacuum cleaner 44 is started, and one end of the aluminum foil is passed through the cleaning frame 41 and attached to the tensioning mechanism 5 and the folding mechanism 1. During the insertion of the aluminum foil, the limiting members 42 can be used to limit the aluminum foil. Under the action of the vacuum cleaner 44, the debris remaining on the aluminum foil enters the cavity 46 through the suction port 47, and then enters the dust bin on the vacuum cleaner 44 through the suction pipe 45 for collection. This facilitates the cleaning and removal of debris from the surface of the aluminum foil, ensuring the cleanliness of the aluminum foil surface and preventing the debris on the surface of the aluminum foil from being squeezed and leaving indentations or even causing damage to the aluminum foil during the subsequent tensioning and folding process.

[0024] Specifically, the limiting component 42 includes a mounting frame 421, a mesh plate 422, an end plate 423, a bidirectional screw 424, a threaded sleeve 425, and a handle 426. The mounting frame 421 is slidably connected to both sides of the cleaning frame 41. The mesh plate 422 is fixedly connected inside the mounting frame 421. The threaded sleeve 425 is fixedly connected to the side wall of the mounting frame 421. End plates 423 are fixedly connected to both ends of one side of the cleaning frame 41. A bidirectional screw 424 is rotatably connected between the two end plates 423. A handle 426 is fixedly connected to one end of the bidirectional screw 424.

[0025] By adopting the above technical solution, the worker holds the handle 426 and applies force to drive the bidirectional screw 424 to rotate. The rotation of the bidirectional screw 424 causes the threaded sleeve 425 to move in opposite directions. The movement of the threaded sleeve 425 causes the mounting frame 421 to move. The movement of the mounting frame 421 causes the mesh plate 422 to move, which facilitates the adjustment of the distance between the two mounting frames 421 and the mesh plate 422. This makes it easier to use the mounting frames 421 and the mesh plate 422 to limit the movement of aluminum foil of different thicknesses, preventing the aluminum foil from shifting or even breaking under the suction of the vacuum cleaner 44.

[0026] Specifically, a guide block is fixedly connected to the end of the cleaning frame 41 away from the end plate 423, and a guide post is fixedly connected between the two guide blocks. A sleeve plate is fixedly connected to the end of the mounting frame 421 away from the threaded sleeve 425 and located outside the guide post.

[0027] By adopting the above technical solution, the moving mounting frame 421 drives the sleeve plate to move along the guide post. With the cooperation of the sleeve plate and the guide post, the moving of the mounting frame 421 can be guided, thereby improving the stability of the moving of the mounting frame 421.

[0028] In this embodiment, during the air filter production process, when the aluminum foil used as raw material for filter element manufacturing needs to be folded, the distance between the two mounting frames 421 is adjusted according to the thickness of the aluminum foil. The operator first holds the handle 426 to apply force, causing the bidirectional screw 424 to rotate. The rotation of the bidirectional screw 424 causes the threaded sleeve 425 to move towards each other. The movement of the threaded sleeve 425 causes the mounting frame 421 to move, and the movement of the mounting frame 421 causes the mesh plate 422 to move. When the two mounting frames 421 are in the appropriate position, the vacuum cleaner 44 is started, and one end of the aluminum foil is passed through the cleaning frame 41 and overlapped onto the tensioning mechanism 5 and the folding mechanism 1. During the insertion of the aluminum foil, the mesh plate 422 is used... 22 can limit the aluminum foil. Under the action of the vacuum cleaner 44, the debris remaining on the aluminum foil enters the cavity 46 through the holes on the mesh plate 422 and the suction port 47. Then, it enters the dust bin on the vacuum cleaner 44 through the suction pipe 45 for collection. This facilitates the cleaning and removal of debris from the aluminum foil surface, ensuring the cleanliness of the aluminum foil surface and preventing the debris on the aluminum foil surface from being squeezed and leaving indentations or even causing damage to the aluminum foil during the subsequent stretching and folding process. Then, the folding mechanism 1 is used to fold the aluminum foil. When the folded aluminum foil reaches a certain length, the cutting mechanism 2 is used to cut the aluminum foil.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that the collection component 3 includes a collection box 31 and an L-shaped rod 35. The collection box 31 is provided on the side of the cutting mechanism 2 away from the folding mechanism 1. The L-shaped rod 35 is fixedly connected to both ends of the side wall of the cutting mechanism 2 on one side of the collection box 31.

[0031] Specifically, the collection assembly 3 also includes a side rod 32, a fixing screw 33, and a fixing hole 34. The side rod 32 is fixedly connected to the side wall of the collection box 31 above the L-shaped rod 35. The fixing screw 33 is threadedly connected to the inside of the side rod 32. The fixing hole 34 is provided inside the L-shaped rod 35 at the position corresponding to the fixing screw 33.

[0032] By adopting the above technical solution, after the collection box 31 moves to fit against the side wall of the L-shaped rod 35, the operator rotates the fixing screw 33 to rotate and move along the side rod 32. When the fixing screw 33 moves and inserts into the inside of the fixing hole 34, the rotation of the fixing screw 33 is stopped. The fixing screw 33 can be used to fix the side rod 32 and the L-shaped rod 35 to ensure the stability of the collection box 31.

[0033] In this embodiment, the collection box 31 is moved to the lower end of the cutting mechanism 2 and made to fit against the side wall of the L-shaped rod 35. The operator rotates the fixing screw 33 to rotate and move along the side rod 32. When the fixing screw 33 moves and inserts into the fixing hole 34, the rotation of the fixing screw 33 is stopped. The fixing screw 33 can be used to fix the side rod 32 and the L-shaped rod 35 to ensure the stability of the collection box 31. After the folded aluminum foil is cut by the cutting mechanism 2, the cut aluminum foil falls into the collection box 31 for collection, which facilitates the storage of the folded aluminum foil.

[0034] In this utility model, the vacuum cleaner 44 is a previously disclosed technology, and the selected model is VCC85S-12.

[0035] The structure and principle of the folding mechanism 1, which consists of a main roller seat, a lower corrugated roller, an upper corrugated roller, a motor, and gears, have been disclosed in an air filter folding and forming device disclosed in Chinese patent application number 202320686268.X. Its working principle is as follows: a main roller seat is fixedly connected between the cutting mechanism 2 and the tensioning mechanism 5. A lower corrugated roller is rotatably connected to the main roller seat. An upper corrugated roller is provided above the lower corrugated roller. A motor is fixedly connected to the side wall of the main roller seat. The output end of the motor is connected to the lower corrugated roller. Both the upper and lower corrugated rollers are coaxially connected to gears. The two gears mesh. In use, aluminum foil passes through the tensioning mechanism 5, the upper corrugated roller, and the lower corrugated roller in sequence. The motor drives the lower corrugated roller to rotate. Under the meshing transmission of the two gears, the upper corrugated roller rotates accordingly. The upper corrugated roller uses its upper corrugated edges to roll the aluminum foil, rolling the flat aluminum foil into a continuous corrugated shape.

[0036] The structure and principle of the cutting mechanism 2, which consists of a blade holder, a cylinder, a cutting blade, a shearing seat, and a cutting seat, have been disclosed in a Chinese patent application (202320686268.X) for an air filter folding and forming device. Its working principle is as follows: a cutting seat is fixedly connected to the side wall of the folding mechanism 1. A blade holder is installed on the cutting seat, and a cylinder is installed on the blade holder. The output end of the cylinder is connected to a cutting blade. A shearing seat is located below the cutting blade and is installed on the cutting seat. The cutting blade is angled. After the aluminum foil is folded using the folding mechanism 1, the folded aluminum foil moves and overlaps onto the cutting seat on the shearing seat. When the folded aluminum foil needs to be cut, the cylinder is activated, causing the cutting blade to move downwards to cut the aluminum foil.

[0037] The structure and principle of the tensioning mechanism 5, which consists of auxiliary roller seats and tensioning rollers, in this utility model have been disclosed in an air filter folding and forming device disclosed in Chinese patent application number 202320686268.X. Its working principle is as follows: auxiliary roller seats are fixedly connected to both ends of the side of the folding mechanism 1 away from the cutting mechanism 2, and tensioning rollers are rotatably connected between the two auxiliary roller seats. Aluminum foil is sequentially inserted into the periphery of multiple tensioning rollers, and the aluminum foil is tensioned and conveyed by the tensioning rollers.

[0038] The working principle and usage process of this utility model: During the production process of the air filter of this utility model, when it is necessary to fold the aluminum foil paper used for filter element manufacturing, the collection box 31 is moved to the lower end of the cutting mechanism 2 and made to fit against the side wall of the L-shaped rod 35. The operator rotates the fixing screw 33, causing it to rotate and move along the side rod 32. When the fixing screw 33 moves and inserts into the fixing hole 34, the rotation of the fixing screw 33 is stopped. The fixing screw 33 can be used to fix the side rod 32 and the L-shaped rod 35, ensuring the stability of the collection box 31. The distance between the two mounting frames 421 is adjusted according to the thickness of the aluminum foil paper. The operator first holds the handle 426 to apply force to drive the bidirectional screw 424 to rotate. The rotation of the bidirectional screw 424 drives the threaded sleeve 425 to move towards each other. The movement of the threaded sleeve 425 drives the mounting frame 421 to move. The movement of the mounting frame 421 drives the mesh plate 422 to move. When the two mounting frames 421 move to the appropriate position... The vacuum cleaner 44 is started, and one end of the aluminum foil is passed through the cleaning frame 41 and attached to the tensioning mechanism 5 and the folding mechanism 1. During the insertion of the aluminum foil, the mesh plate 422 can limit the aluminum foil. Under the action of the vacuum cleaner 44, the debris remaining on the aluminum foil enters the cavity 46 through the holes on the mesh plate 422 and the suction port 47, and then enters the dust bin on the vacuum cleaner 44 through the suction pipe 45 for collection. This facilitates the cleaning and removal of debris from the surface of the aluminum foil, ensuring the cleanliness of the aluminum foil surface and preventing the debris on the surface of the aluminum foil from being squeezed and leaving indentations or even causing damage to the aluminum foil during the subsequent tensioning and folding process. The folding mechanism 1 is then used to fold the aluminum foil. When the folded aluminum foil reaches a certain length, the cutting mechanism 2 is used to cut the aluminum foil. The cut aluminum foil falls into the collection box 31 for collection, making it easy to store and place the folded aluminum foil.
