Description

Technical Field

[0001] This utility model relates to the field of fiber filter material processing technology, and in particular to a fiber filter material cutting machine. Background Technology

[0002] In the field of fiber filter media processing, to meet the needs of subsequent processing, transportation, and installation, it is often necessary to cut rolls of long strips of filter media into segments of specific lengths. The efficiency and safety of this cutting process directly affect the overall production rhythm and operational standardization of filter media processing.

[0003] Currently, semi-automatic cutting mechanisms are widely used in the industry to complete the aforementioned cutting operations. However, such mechanisms pose significant operational safety hazards in practical applications: when cutting filter media, to prevent displacement due to cutting force and ensure cutting accuracy, operators need to use heavy objects to press down or directly press the media with their hands to assist in fixing it. Using heavy objects to press down is not only cumbersome, but deviations in the placement of the heavy objects may affect the fixing effect, leading to errors in cutting dimensions. More importantly, directly using hand pressing during the high-speed operation of the cutting blade can easily cause accidents due to operational errors or sudden equipment malfunctions, posing a serious threat to the personal safety of operators. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fiber filter media cutting machine, which solves the design defects in the filter media fixing method of existing fiber filter media cutting machines mentioned in the background art, resulting in insufficient operational safety in the fiber filter media cutting operation.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A fiber filter media cutting machine includes a belt conveyor for conveying filter media; a mounting base is provided on one side of the belt conveyor, and two top grooves are provided on the top surface of the mounting base, each top groove extending along the length of the mounting base; a first pressure plate that can move vertically is provided in the top groove near the belt conveyor, and the first pressure plate is used to press one end of the filter media; a second pressure plate that can move along the length of the top groove is also provided in the top groove, and the second pressure plate can also move vertically, and the second pressure plate is used to press the other end of the filter media; a hot pressure roller and a cutting blade that can move along the length of the top groove are provided in the other top groove, the hot pressure roller is used to flatten the curled filter media; the cutting blade is located on the side of the hot pressure roller near the first pressure plate, and is used to cut the filter media.

[0007] Working principle:

[0008] In use, place one end of the curled filter media under the first pressure plate and lay it flat on the belt conveyor. Then, move the first pressure plate downwards to press down on that end of the filter media. Next, move the second pressure plate away from the first pressure plate and move it downwards to press down on the other end of the filter media. Then, move the hot pressure roller from the first pressure plate towards the second pressure plate to flatten the filter media. Then, the cutting blade cuts the filter media. After cutting, start the belt conveyor, release the pressure of the first pressure plate, and continue to transport and collect the cut filter media forward. At the same time, the second pressure plate moves the pressed filter media synchronously with the belt conveyor, causing the curled filter media to lay flat on the belt conveyor. After traveling a certain distance, the first pressure plate moves downwards to press down on the end of the filter media, and the pressure of the second pressure plate is released. Repeat the above operation for subsequent cutting.

[0009] Beneficial effects:

[0010] 1. The automatic fixing of both ends of the filter media is achieved through the vertical movement of the first and second pressure plates, completely replacing the traditional method of manual pressing or heavy object pressing. This fundamentally avoids the safety hazard of operators' hands coming into contact with the cutting blade, significantly reducing the risk of safety accidents. Simultaneously, after cutting, the coordinated action of the belt conveyor and the second pressure plate (the conveyor belt transports the cut filter media, and the second pressure plate drives the remaining filter media to be laid out synchronously) forms a continuous "fixing-cutting-conveying-re-fixing" operation process, reducing manual intervention, achieving semi-automatic cutting, and reducing the labor intensity of operators.

[0011] 2. The first and second pressure plates firmly press down on both ends of the filter media, effectively preventing displacement due to stress during the cutting process. The hot press rollers flatten the curled filter media before cutting, ensuring a smooth surface and avoiding dimensional deviations caused by wrinkles. Furthermore, the "traction-flattening" action of the second pressure plate, moving synchronously with the belt conveyor, ensures the filter media remains stretched during transport, providing a stable reference for subsequent repeated cutting and further improving dimensional consistency in batch cutting.

[0012] 3. The second pressure plate can move flexibly along the length of the top groove, and in conjunction with the conveyor belt distance adjustment, it can adapt to the cutting requirements of filter media of different lengths and specifications, meeting diverse processing requirements without changing equipment or making significant structural adjustments. At the same time, the continuous operation process reduces the preparation time for single-segment cutting (such as manual material laying and positioning), significantly improving the cutting efficiency per unit time, and is suitable for large-scale production scenarios.

[0018] Example:

[0019] like Figures 1-3 As shown, a fiber filter media cutting machine includes a belt conveyor 1 for conveying filter media. It should be noted that the belt conveyor 1 is existing technology and includes a frame, conveyor belt, drive unit, and other structures. Its working principle is as follows: after the motor starts, it drives the input shaft of the reducer to rotate through a coupling. The output shaft of the reducer transmits power to the drive roller, causing the drive roller to rotate around its own axis. There is friction between the drive roller and the conveyor belt. When the drive roller rotates, the friction drives the conveyor belt to move along the length of the frame. The driven roller passively rotates with the movement of the conveyor belt, forming a continuous cyclic conveying path. During the filter media cutting process, the belt conveyor 1 can start, stop, or adjust its conveying speed according to the cutting rhythm. It coordinates with the fixing actions of the first pressure plate 4 and the second pressure plate 5, the flattening action of the hot pressure roller 6, and the cutting action of the cutting blade 7 to ensure that the filter media can stably complete subsequent processing steps after being conveyed to the designated position. The conveyor belt of belt conveyor 1 is usually made of materials such as rubber and canvas, which are relatively soft and have a certain degree of elasticity. It is mainly used to carry and transport filter materials. In this solution, the conveyor belt of belt conveyor 1 is embedded with a high-strength fiber layer, which can block the direct contact between the blade and the conveyor belt, avoid the conveyor belt being torn or worn, and prevent the conveying function from being affected by the damage to the conveyor belt.

[0020] A mounting base 2 is provided on one side of the belt conveyor 1, and a mounting base 2 is also provided on the other side of the belt conveyor 1. The top surface of the mounting base 2 is provided with two top grooves 3, each of which extends along the length of the mounting base 2. A first pressure plate 4 that can move vertically is provided in the top groove 3 near the belt conveyor 1. The first pressure plate 4 is used to press one end of the filter material. A second pressure plate 5 that can move along the length of the top groove 3 is also provided in the top groove 3. The second pressure plate 5 can also move vertically and is used to press the other end of the filter material. A hot pressure roller 6 and a cutting blade 7 that can move along the length of the top groove 3 are provided in the other top groove 3. The hot pressure roller 6 is used to flatten the curled filter material. The cutting blade 7 is located on the side of the hot pressure roller 6 near the first pressure plate 4 and is used to cut the filter material.

[0021] like Figure 1 and Figure 2 As shown, a support rod 8 is bolted to the top trough 3 near the belt conveyor 1. The axial direction of the support rod 8 is parallel to the length direction of the top trough 3. A first base block 801 is fixed to the outer periphery of the support rod 8. A first electric telescopic rod 802 is bolted to the top surface of the first base block 801. The telescopic end of the first electric telescopic rod 802 faces upward. One end of the first pressure plate 4 is bolted to the telescopic end of the first electric telescopic rod 802. The vertical movement of the first pressure plate 4 can be precisely controlled by the telescopic movement of the first electric telescopic rod 802, thereby achieving stable pressing or releasing of one end of the filter material. On the other side of the belt conveyor 1, a first limiting rod 13 is fixedly installed in the top groove 3 near the belt conveyor 1 by bolts on the mounting base 2. The first limiting rod 13 is parallel to the support rod 8. A fixing block 14 is fixedly installed on the outer periphery of the first limiting rod 13. A telescopic rod is fixedly installed on the top surface of the fixing block 14 by bolts. The other end of the first pressure plate 4 is fixedly connected to the telescopic end of the telescopic rod by bolts. The above structure is designed to cooperate with the telescopic movement of the first electric telescopic rod 802 and improve the stability of the first pressure plate 4 when it moves vertically. Since the structure is only designed to improve the stability of the first pressure plate 4 when it is working, it is not described in the claims.

[0022] like Figure 1 and Figure 3As shown, a rotatable first shaft 9 is also provided on the inner wall of the top trough 3 near the belt conveyor 1 via a bearing. It should be noted that the method of achieving rotational connection via a bearing is existing technology, and those skilled in the art should be familiar with its structure, principle, etc., which will not be elaborated further. The first shaft 9 is parallel to the length direction of the top trough 3. A first motor 901 is fixed to the outer wall of the mounting base 2 by bolts. The first shaft 9 passes through the side wall of the mounting base 2 and is connected to the output end of the first motor 901 via a coupling. The other end of the first shaft 9 is connected to the other end of the support rod 8 via a bearing. The first shaft 9 is a threaded rod. A second bottom block 902 is threadedly connected to the outer circumference of the first shaft 9. The side wall of the second bottom block 902 abuts against the inner wall of the top trough 3. A second electric telescopic rod 903 is fixed to the top surface of the second bottom block 902 by bolts. The telescopic end of the second electric telescopic rod 903 faces upward. One end of the second pressure plate 5 is fixed to the telescopic end of the second electric telescopic rod 903 by bolts. When the first motor 901 starts, it drives the first rotating shaft 9 to rotate. Since the second bottom block 902 abuts against the inner wall of the top groove 3, its rotation is restricted, allowing the second bottom block 902 to move axially along the first rotating shaft 9. This, in turn, drives the second pressure plate 5 to move along the length of the top groove 3. Combined with the extension and retraction of the second electric telescopic rod 903, the other end of the filter material is pressed and its position adjusted. The outer periphery of the first limiting rod 13 is also slidably connected to a first moving block 15 that can move axially. The top surface of the first moving block 15 is fixed with a telescopic rod by bolts. The other end of the second pressure plate 5 is fixed to the extension and retraction end of the telescopic rod by bolts. The first limiting rod 13 and the first moving block 15 are designed to improve the stability of the second pressure plate 5 when it moves axially along the first limiting rod 13. The telescopic rod is designed to cooperate with the extension and retraction of the second electric telescopic rod 903 to improve the stability of the second pressure plate 5 when it moves vertically. This structure is designed solely to improve the stability of the second pressure plate 5 during operation.

[0023] like Figure 1 and Figure 2As shown, a second motor 101 is bolted to the outer wall of the mounting base 2. The output end of the second motor 101 is connected to a second rotating shaft 10, which is axially parallel to the length direction of the top groove 3, via a coupling. The second rotating shaft 10 rotatably passes through the side wall of the mounting base 2 and is rotatably positioned within another top groove 3. The second rotating shaft 10 is a threaded rod, and a third bottom block 102 is threadedly connected to its outer circumference. The side wall of the third bottom block 102 abuts against the inner wall of the top groove 3. A top support rod 103 is bolted to the top surface of the third bottom block 102. A long plate 104 is bolted to the top of the top support rod 103. A third electric telescopic rod 105 is bolted to the side of the long plate 104 facing the belt conveyor 1. The telescopic end of the third electric telescopic rod 105 faces downwards, and the cutting blade 7 is connected to the telescopic end of the third electric telescopic rod 105. The cutting blade 7 is made of high-speed steel, which contains alloying elements such as tungsten, chromium, and vanadium, and has high hardness and wear resistance, and its toughness is superior to that of cemented carbide. When the second motor 101 is working, it drives the second rotating shaft 10 to rotate. With the cooperation of the third bottom block 102 and the inner wall of the top groove 3, the third bottom block 102 moves axially along the second rotating shaft 10, driving the long plate 104 and the cutting blade 7 to move. The third electric telescopic rod 105 controls the vertical movement of the cutting blade 7 to complete the cutting action. On the other side of the belt conveyor 1, on the mounting base 2, a second limiting rod 16 is fixedly installed in another top groove 3 by bolts. The second limiting rod 16 is parallel to the second rotating shaft 10. A second moving block 17 that can move axially is slidably connected to the outer periphery of the second limiting rod 16. A top support rod 103 is also fixedly installed on the top surface of the second moving block 17 by bolts. The two ends of the long plate 104 are fixedly connected to the two top support rods 103 by bolts. The above structure is designed to cooperate with the movement of the third bottom block 102 and improve the stability of the long plate 104 when it moves. This structure is only designed to improve the stability of the long plate 104 when it is working.

[0024] like Figure 1 and Figure 3 As shown, a fourth electric telescopic rod 106 is bolted to the side of the long plate 104 facing the belt conveyor 1. The telescopic end of the fourth electric telescopic rod 106 faces downward, and the hot press roller 6 is connected to the telescopic end of the fourth electric telescopic rod 106. The roller body integrates a heating element (when the hot press roller 6 is energized, the internal heating element raises the roller surface temperature, and the heat is transferred to the filter material surface through the roller surface), enabling the roller surface to reach a preset temperature (the temperature can be adjusted according to the characteristics of the filter material). The fourth electric telescopic rod 106 can adjust the height of the hot press roller 6, allowing it to contact the filter material and apply a certain pressure for flattening (the pressure is controlled by the telescopic amount of the fourth electric telescopic rod 106, ensuring that the filter material is flattened without damaging the fiber structure). Simultaneously, as the long plate 104 moves, the hot press roller 6 can fully flatten the filter material.

[0025] like Figure 3As shown, the telescopic end of the fourth electric telescopic rod 106 is fixed to a connecting plate 11 by bolts. Auxiliary blocks 12 are fixed to both ends of the connecting plate 11 facing the belt conveyor 1 by bolts. The hot press roller 6 is rotatably positioned between the two auxiliary blocks 12. This arrangement allows the hot press roller 6 to rotate flexibly, making it smoother when flattening the filter material and improving the flattening effect.

[0026] Working principle:

[0027] In use, place one end of the curled filter material under the first pressure plate 4 and lay it flat on the belt conveyor 1. Start the first electric telescopic rod 802 to extend its telescopic end, causing the first pressure plate 4 to move downwards and press down on that end of the filter material. According to the required cutting length of the filter material, start the first motor 901 to move the second bottom block 902 to move the second pressure plate 5 along the length direction of the top groove 3 to a suitable position. Then start the second electric telescopic rod 903 to move the second pressure plate 5 downwards and press down on the other end of the filter material. Next, start the second motor 101 to move the third bottom block 102 to move the long plate 104, the hot press roller 6, and the cutting blade 7. At the same time, start the fourth electric telescopic rod 106 to move the hot press roller 6 to press down on the other end of the filter material. Roller 6 contacts the filter material, and the hot press roller 6 moves from the first pressure plate 4 to the second pressure plate 5 to flatten the filter material. After flattening, the third electric telescopic rod 105 is activated to drive the cutting blade 7 to move downward to complete the cutting of the filter material. After cutting, the belt conveyor 1 is activated to release the pressure of the first pressure plate 4, and the cut filter material is continuously conveyed forward and collected. At the same time, the second pressure plate 5 drives the pressed filter material to move synchronously with the operation of the belt conveyor 1, and the curled filter material is spread flat on the belt conveyor 1. After running for a certain distance, the first pressure plate 4 moves downward to press the end of the filter material and releases the pressure of the second pressure plate 5. The above operation is repeated for subsequent cutting.
