Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of filter paper folding, and more specifically, to a filter paper folding device for air filter production. Background Art

[0002] The filter element of a filter usually achieves the filtering effect through filter paper. Generally, the filtering substances refer to impurities, fine particles, pollen, bacteria, industrial waste gas, dust, etc. contained in the air. The effect of an air filter is to prevent such substances from entering the air conditioning system and damaging the air conditioning system, and to create a good air environment. The air filter usually increases the contact area with the filtered substances through the filter paper with a serrated structure to improve the filtering efficiency, so the filter paper needs to be folded during production.

[0003] The working principle of the filter paper folding device in the prior art is to drive the roller to rotate by an electric motor, and the filter element is sent into the folding device through a transmission device, and then the folding of the filter element is completed through a series of folding actions. The filter element is placed on the supply device, and the supply device sends the filter element into the folding device in sequence. The folding device usually consists of a series of folding plates, guide plates and positioning devices, and can fold the filter element in a predetermined folding manner. Usually, the folding plates will perform actions such as up and down folding, left and right folding or cross folding, so that the filter element can be folded multiple times. The folded filter element is sent out of the folding device, and then it is necessary for workers to cut the folded filter paper into a specific length and then curl and paste it. Manual cutting is inefficient because it requires manual counting, and it is difficult to ensure accuracy and stability. At present, there are also folding devices that add cutting devices to cut the filter paper after folding. However, generally, when the conveyor needs to stop running, a cutter is used to cut the filter paper, that is, the cutting step affects the continuity of the folding step, and the cutting efficiency is low.

[0025] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0026] As Figures 1 to 9 shown, it shows a filter paper folding device for air filter production in an embodiment of this disclosure, which includes a frame body 1, a conveying mechanism 2, and a folding mechanism 3, and also includes a receiving plate 4, a baffle 5, a camera 6, and a cutting mechanism. The conveying mechanism 2 and the folding mechanism 3 are the existing structures of a known paper folding machine in the art and are not the main innovative points of this disclosure. The conveying mechanism 2 selects conveying rollers, and the rotation of the conveying rollers is used to tension and transport the filter paper, so that the filter paper is conveyed to the folding mechanism 3. The folding mechanism 3 can select a drum-type folding mechanism 3. For the paper to be folded, it is held by a pick needle and rotated on a folding drum and an output drum. On the line connecting the centers of the drums, an elastic folding knife pushes the paper into the gap of the drum, and the clamping plate clamps it along the folding line and is taken away by the drum. The folding knife withdraws from the folding seam, and the folding of the paper is completed by the cooperation of the folding knife of one drum and the clamping plate of another drum during relative rolling. It can also use the method of multiple folding plates, and the paper is folded into the required shape by the up and down movement of multiple folding plates, and the movement of the folding plates is controlled by a transmission device.

[0027] The receiving plate 4 is fixedly connected to the frame body 1 and is used to receive and convey the folded filter paper. Under the action of the conveying mechanism 2, the filter paper is conveyed to the folding mechanism 3 for folding. The folded filter paper is then pushed onto the receiving plate 4 for conveying under the action of the subsequent filter paper pusher.

[0028] The baffle 5 is movably arranged on the receiving plate 4 and is used to block the folded filter paper. An electric cylinder 7 is installed on the receiving plate 4. The baffle 5 is fixedly connected to the output end of the electric cylinder 7. The baffle 5 is located at one end of the receiving plate 4 away from the frame body 1. The folded filter paper is pushed onto the receiving plate 4 and blocked by the baffle 5 at the end, preventing the filter paper from falling off the receiving plate 4, thus facilitating the subsequent counting and cutting of the creases of the filter paper. After cutting, the electric cylinder 7 can drive the baffle 5 away from the receiving plate 4, allowing the cut filter paper to fall from the receiving plate 4 for subsequent processing. Then, the electric cylinder 7 drives the baffle 5 back to its original position to block the subsequent filter paper.

[0029] The camera 6 is installed on the receiving plate 4 and is used to photograph the number of folded filter papers. When the filter paper is blocked by the baffle 5, the camera can photograph the filter paper image and transmit the image to the supporting data processor. The data processor judges the number of creases of the filter paper, thereby controlling the cutter 102 to move to the corresponding crease and cutting the filter paper into the required length. Multiple cameras can be used to photograph different positions of the filter paper to ensure accurate counting of the creases or folds. The position of the pressing plate 101 can also be photographed and calibrated by the camera 6 to make the position of the pressing plate 101 correspond to the crease.

[0030] The cutting mechanism is used to accurately cut the folded filter paper. The cutting mechanism includes a pressing plate 101 and a cutter 102. The pressing plate 101 is movable and can be lifted and lowered on the receiving plate 4. The receiving plate 4 is equipped with an electric cylinder 2 103. The output end of the electric cylinder 2 103 is equipped with an electric cylinder 3 104. The pressing plate 101 is fixedly connected to the output end of the electric cylinder 3 104. The electric cylinder 2 103 can drive the pressing plate 101 to move along the receiving plate 4, and cooperate with the camera to move the pressing plate 101 to the fold to be cut. The electric cylinder 3 104 drives the pressing plate 101 to descend, and the pressing plate 101 is inserted into the fold to be cut. The length of the pressing plate 101 is adapted to the width of the filter paper. In order to facilitate the pressing plate 101 to be stuck in the fold of the filter paper, the pressing plate 101 is V-shaped. The bottom end of the pressing plate 101 is in the shape of a sheet. The bottom end of the pressing plate 101 is relatively thin, which is convenient for inserting into the fold of the filter paper. At the same time, as the pressing plate 101 descends, the pressing plate 101 can open the fold of the filter paper. At the same time, as the pressing plate 101 contacts the bottom end of the fold, the fold can be limited by the pressing plate 101, so that the fold and the bottom edge of the pressing plate 101 are aligned, that is, the fold is kept in a straight line. A bottom-opening cutting cavity is provided on the pressing plate 101, and the cutter 102 is movably arranged in the cutting cavity. A screw feeding mechanism 105 is installed on the pressing plate 101, and the cutter 102 is fixedly connected to the moving nut seat of the screw feeding mechanism 105. The screw feeding mechanism 105 can drive the cutter 102 to move along the pressing plate 101, and the bottom of the cutter 102 The edge of the bottom is slightly lower than the pressing plate 101. After the pressing plate 101 contacts the bottom end of the fold of the filter paper, the filter paper can be cut by moving the cutter 102. The cutter 102 moves along the pressing plate 101, and the fold is limited by the pressing plate 101, thereby ensuring that the cutter 102 accurately cuts the filter paper along the fold. In order to reduce the damage of the receiving plate 4, a cutting groove is provided on the receiving plate 4, and a cutting plate 106 is detachably installed inside the cutting groove. The cutting plate 106 and the cutter 102 cooperate to cut the filter paper. The cutting plate 106 is soft and can be made of rubber or wood. The cutter 102 can cut into the inside of the cutting plate 106. At the same time, the cutting plate 106 supports the filter paper and the filter paper is cut by moving the cutter 102. The cutting groove has a certain width. When the filter paper and the baffle 5 contacts and accumulates in the cutting area, the position of the fold to be cut is within a certain interval, and the cutting groove is located in the interval, so that when the pressing plate 101 and the cutting knife 102 are lowered, the positions of the cutting knife 102 and the cutting plate 106 correspond to each other. In order to replace the cutting plate 106, a clamping rod 107 is slidably installed on the receiving plate 4, and a clamping groove matching the clamping rod 107 is opened on the cutting plate 106. The cutting plate 106 is limited by the clamping rod 107 to ensure the stability of the cutting plate 106. After a certain period of time, the cutting plate 106 needs to be replaced after a certain amount of cutting. The clamping rod 107 is pulled out from the inside of the clamping groove to release the limit on the cutting plate 106. The cutting plate 106 can be disassembled and replaced, and the replaced cutting plate 106 is installed into the inside of the cutting groove.Just push the card rod 107 into the inside of the card slot to fix the cutting plate 106.

[0031] To improve the accuracy of counting and cutting the filter paper, a fixing component is further included. The fixing component is used to clamp and fix the filter paper at the cutting position. The fixing component includes two clamping plates 201. The clamping plates 201 are movably arranged on the receiving plate 4. A support frame 202 is fixedly connected to the receiving plate 4. A motor 203 is installed on the support frame 202. The output end of the motor 203 is fixedly connected to a bidirectional screw 204. The two clamping plates 201 and the two threaded sections of the bidirectional screw 204 correspond one by one. The clamping plates 201 are provided with internal threaded holes matching the bidirectional screw 204. The two clamping plates 201 are symmetrically arranged with respect to the bidirectional screw 204 and the receiving plate 4. The clamping plates 201 are fixedly connected with sliding rods, and the sliding rods are in sliding fit with the support frame 202. And the support frame 202 is provided with a through hole for the clamping plate 201 to pass through. By driving the bidirectional screw 204 to rotate through the motor 203, the two clamping plates 201 can be driven to approach each other, so as to press the folded filter paper and ensure that the filter paper at the cutting position is in a stable state, so as to facilitate the camera to photograph the filter paper and facilitate moving the pressing plate 101 to the corresponding cutting position. The two clamping plates 201 are in contact with both sides of the filter paper. To reduce the blockage of the clamping plate 201 to the lifting of the pressing plate 101, the clamping plate 201 is made of an elastic material, and the clamping plate 201 is in contact with the side of the pressing plate 101. The clamping plate 201 can be selected from rubber or leather, which can clamp the filter paper to a certain extent to ensure its stable state, and at the same time reduce the obstruction to the movement and lifting of the clamping plate 201.

[0032] To ensure the stability of the filter paper after folding, a limiting component is further included. The limiting component is used to limit the folded filter paper. The limiting component includes a protective cover 301, a limiting frame 302 and a limiting roller 303. The protective cover 301 is fixedly connected to the top of the receiving plate 4. A plurality of limiting frames 302 are provided. The limiting frames 302 are connected to the inner top wall of the protective cover 301 through compression springs and telescopic rods. The limiting roller 303 is rotatably connected to the limiting frame 302. The limiting roller 303 is in contact with the top of the filter paper. An iron plate is installed on one side of the folding mechanism 3 close to the receiving plate 4, which can limit the top of the folded filter paper, ensure the folding accuracy, reduce the movement of the filter paper, and ensure the stability of the filter paper. Under the action of the compression spring, the limiting frame 302 can be driven to press the limiting roller 303 against the top of the folded filter paper, that is, the bottom end of the limiting roller 303 is flush with the bottom end of the iron plate, so as to limit the folded filter paper. At the same time, the rotation of the limiting roller 303 can reduce the resistance generated by the transfer of the filter paper.

[0033] To reduce the resistance of filter paper cutting, a drying mechanism is further included. The drying mechanism is used to dry the folded filter paper. The drying mechanism includes a heating box 401 and a heater 402. The heating box 401 is fixedly connected to the protective cover 301, and the heater 402 is installed inside the heating box 401. The heater 402 is energized to generate heat and heats the heating box 401. The heat of the heating box 401 is transferred to the inside of the protective cover 301, and the filter paper inside it can be heated to keep the filter paper in a dry state, facilitating the cutting of the filter paper.

[0034] To further improve the drying effect of the filter paper, the limiting roller 303 is of a hollow structure. The limiting roller 303 is communicated with the heating box 401. Two adjacent limiting rollers 303 are communicated through a connecting pipe 8. The two ends of the connecting pipe 8 are rotationally communicated with the two limiting rollers 303. The limiting roller 303 at the end is communicated with the heating box 401 through a telescopic hose 9. The lifting of the limiting frame 302 and the limiting roller 303 can be realized through the telescopic hose 9 to press the filter paper. A blower 10 is installed on the heating box 401, and the heating box 401 is communicated with the air outlet of the blower 10. A plurality of air outlet holes are provided on the limiting roller 303. The blower 10 sends air into the inside of the heating box 401, the heater 402 heats the air entering the heating box 401, and at the same time the blower 10 conveys the hot air to the inside of the limiting roller 303, and then the hot air is blown out through the air outlet holes. The hot air is blown into the inside of the protective cover 301, and at the same time the limiting roller 303 contacts the filter paper, which can improve the drying effect of the filter paper and further improve the convenience of cutting the filter paper.

[0035] To reduce the dust and impurities on the filter screen, the heating box 401 is communicated with a purging pipe 11. The purging pipe 11 is communicated with a plurality of nozzles 12. The nozzles 12 face the folding mechanism 3. Under the action of the blower 10, part of the hot air in the heating box 401 enters the inside of the purging pipe 11 and is blown towards the folding mechanism 3 through the nozzles 12, heating and purging the surface of the filter paper during the folding process. While improving the drying effect of the filter paper, the residue of dust and impurities on the surface of the filter paper is reduced, thus ensuring the purification effect of the filter paper.

[0036] The working principle or usage process of this filter paper folding device for air filter production is as follows: The filter paper passes through the conveying mechanism 2 and the folding mechanism 3. The conveying mechanism 2 transfers the filter paper, and the folding mechanism 3 folds the filter paper into the required shape. The folded filter paper is transferred to the receiving plate 4 under the push of the subsequent filter paper. The filter paper is limited by the limiting roller 303. At the same time, the blower 10 sends air into the inside of the heating box 401, the heater 402 heats the air, part of the hot air is blown out through the purging pipe 11 and the nozzles 12, preheating and purging the filter paper at the folding mechanism 3, part of the hot air enters the inside of the limiting roller 303 and is blown out through the air outlet holes to heat and dry the filter paper in the protective cover 301; The folded filter paper after drying is transferred to the cutting area. The end of the filter paper contacts the baffle 5. The motor 203 drives the bidirectional screw 204 to rotate, driving the clamping plate 201 to clamp and fix the filter paper. The camera takes pictures of the filter paper and transmits the images to the data processor. The data processor identifies and counts the number of creases of the filter paper, controls the movement of the second electric cylinder 103, and drives the pressing plate 101 to move above the crease to be cut. After the movement is completed, the camera takes pictures of the pressing plate 101 and the filter paper again to ensure that the positions of the pressing plate 101 and the crease correspond. Then, the third electric cylinder 104 drives the pressing plate 101 to descend, and the pressing plate 101 is inserted into the crease at the cutting position. The pressing plate 101 and the bottom end of the crease are closely attached to limit it. The lead screw feed mechanism 105 drives the cutter 102 to move to cut the filter paper; Then the motor 203 rotates in reverse to make the clamping plate 201 move away from the filter paper. The first electric cylinder 7 drives the baffle 5 to move away from the receiving plate 4. The third electric cylinder 104 drives the pressing plate 101 to rise a certain height. The second electric cylinder 103 drives the pressing plate 101 to move towards the baffle 5 to push the cut filter paper off the receiving plate 4, and then subsequent processing of the filter paper can be carried out. Then, the second electric cylinder 103 drives the pressing plate 101 to return to the original position, that is, the cutting position. The first electric cylinder 7 drives the baffle 5 to return to the original position, that is, the end of the receiving plate 4. The third electric cylinder 104 drives the pressing plate 101 to rise, and the subsequent filter paper continues to be conveyed and is in close contact with the baffle 5 to carry out subsequent cutting work.
