Description

Technical Field

[0001] This utility model relates to a filter element cutting mechanism for air filters, belonging to the field of air filter manufacturing. Background Technology

[0002] Air filter paper is a material specifically used in air filters. Its main function is to capture particulate matter, dust, pollen, bacteria, and other harmful substances in the air, ensuring that the air quality passing through the filter meets the expected standards. A band saw is a common device for cutting filter elements in air filters. Cutting the filter element with a band saw blade makes it easier to obtain a filter element of the appropriate size. The band saw blade is ring-shaped and supported by two pulleys arranged vertically. When the band saw blade rotates around the pulleys under the drive of a motor, there is a long exposed section of the band saw blade near the worktable. To prevent damage to the band saw blade due to unbalanced forces when the filter element comes into contact with the blade, two opposing clamps are usually installed on the exposed section of the band saw blade near the worktable. These clamps provide support for the band saw blade. Because the clamps need to contact the band saw blade, the clamps wear out. When the clamps wear out and can no longer contact the band saw blade, the operator may not notice in time, leaving the band saw blade in a state without support for a period of time. This increases the probability of damage to the band saw blade due to unbalanced forces. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a filter element cutting mechanism for air filters, thereby solving the problems mentioned in the background section. This invention provides a warning when the exposed part of the band saw blade on the processing table is not supported, reducing the probability of the band saw blade being damaged by unbalanced forces.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a filter element cutting mechanism for an air filter, comprising a band saw housing, the band saw housing having a "C"-shaped structure, an upper pulley rotatably mounted at the upper part of the band saw housing, and a lower pulley rotatably mounted at the lower part of the band saw housing, the upper pulley and the lower pulley being connected by a band saw blade, a processing table being provided between the upper pulley and the lower pulley, the band saw blade passing through the processing table, a lifting seat being provided on the upper side of the processing table, the lifting seat being connected to the band saw housing via an adjusting component, two guide holes being provided on the side of the lifting seat facing the band saw blade, studs being inserted into both guide holes, and first positioning screws being threadedly connected to the two sides of the lifting seat adjacent to the guide holes, a rolling bearing in contact with the band saw blade being fitted onto the end of the stud near the band saw blade, an end plate being provided on one side of the rolling bearing, the end plate being connected and fixed to the stud, and a limiting nut threadedly connected to the stud being provided on the side of the rolling bearing away from the end plate.

[0005] Furthermore, the adjusting component includes a boom, the boom is mounted on the upper surface of the lifting seat, the upper end of the boom is fitted with an ear seat, the ear seat is connected and fixed to the band saw shell, and the side of the ear seat facing away from the band saw shell is threaded with a second positioning screw for limiting the relative position of the ear seat and the boom.

[0006] Furthermore, the ear seat has a second threaded hole on the side facing away from the band saw shell, and the second positioning screw is threaded into the second threaded hole.

[0007] Furthermore, the upper surface of the ear seat has a rectangular opening that penetrates the ear seat, and the cross-section of the suspension rod is rectangular, with the suspension rod penetrating through the rectangular opening.

[0008] Furthermore, two columns are installed at the bottom of the band saw housing, and a base is installed at the lower end of the columns. A motor is provided on one side of the band saw housing, and the output shaft of the motor is connected to the lower pulley. Two support legs are installed at the bottom of the motor, and the lower ends of the support legs are connected and fixed to the base.

[0009] Furthermore, a slider is rotatably mounted at the center of one side of the upper pulley. Guide rails for limiting the movement trajectory of the slider are provided on both sides of the slider. The guide rails are arranged vertically and are installed inside the band saw housing by multiple sets of bolts. A screw is mounted on the upper surface of the slider. The upper end of the screw extends to the upper side of the band saw housing, and an adjusting nut is threaded to the end of the screw on the upper side of the band saw housing.

[0010] Furthermore, the lifting seat has a first threaded hole on each of the two sides adjacent to the guide hole. The first threaded hole communicates with the guide hole, and the first positioning screw is threaded into the first threaded hole.

[0011] Furthermore, a strip groove is formed on one side of the upper surface of the processing table, and the band saw blade passes through the strip groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. The outer rings of the two rolling bearings are in contact with the two sides of the band saw blade. When the band saw blade rotates around the upper and lower pulleys under the drive of the motor, the band saw blade will drive the outer rings of the rolling bearings to rotate. On the one hand, the two rolling bearings work together to support the band saw blade. On the other hand, when the outer rings of the rolling bearings are worn and no longer in contact with the band saw blade, the outer rings of the rolling bearings will stop rotating. This provides an indication that the band saw blade has lost support, making it easy for personnel to stop the machine in time to replace the rolling bearings and reduce the probability of the band saw blade being damaged by unbalanced forces.

[0014] 2. Adjust the position of the stud along the guide hole. At this time, the relative position of the rolling bearing and the band saw blade changes. After the wear area of ​​the outer ring of the rolling bearing is misaligned with the band saw blade, the relative position of the stud and the lifting seat can be restricted by the first positioning screw, which helps to improve the utilization rate of the rolling bearing.

[0015] 3. Adjust the position of the suspension rod along the rectangular opening on the ear seat. At this time, the height of the lifting seat changes, that is, the relative position of the rolling bearing and the band saw blade changes, so as to adjust the distance between the rolling bearing and the processing table according to the size of the filter element.

[0016] 4. Tighten the adjusting nut to move the screw upward, which in turn moves the slider upward along the guide rail. The slider then drives the upper pulley upward, thereby increasing the distance between the upper and lower pulleys and achieving the purpose of adjusting the tension of the band saw blade.

A strip groove 15 is opened on one side of the upper surface of the processing table 11. The band saw blade 2 passes through the strip groove 15. The design of the strip groove 15 facilitates the mutual assembly of the band saw blade 2 and the processing table 11.

[0025] See Figures 1-3 Two columns 13 are installed at the bottom of the band saw housing 1, and a base 14 is installed at the lower end of the columns 13. A motor 19 is installed on one side of the band saw housing 1. The output shaft of the motor 19 is connected to the lower pulley 12. Two support legs 20 are installed at the bottom of the motor 19. The lower ends of the support legs 20 are connected and fixed to the base 14. A slider 23 is rotatably installed in the middle of one side of the upper pulley 3. Guide rails 21 are provided on both sides of the slider 23 to limit the movement trajectory of the slider 23. The guide rails 21 are arranged vertically and are installed in the band saw housing 1 by multiple sets of bolts. A screw 22 is installed on the upper surface of the slider 23. The upper end of the screw 22 extends to the upper side of the band saw housing 1. An adjusting nut 4 is threaded to the upper end of the screw 22 on the upper side of the band saw housing 1. Tightening the adjusting nut 4 causes the screw 22 to move upward, thereby moving the slider 23 upward along the guide rail 21. The slider 23 drives the upper pulley 3 to move upward, thereby increasing the distance between the upper pulley 3 and the lower pulley 12, achieving the purpose of adjusting the tension of the band saw blade 2.

[0026] See Figure 1 , Figure 2 and Figure 4 A lifting seat 6 is provided on the upper side of the processing table 11. A hanging rod 5 with a rectangular cross-section is installed on the upper surface of the lifting seat 6. An ear seat 17 is fitted on the upper end of the hanging rod 5, that is, the hanging rod 5 passes through the rectangular opening of the ear seat 17 on the upper surface of the ear seat 17. The ear seat 17 is connected and fixed to the band saw shell 1. A second positioning screw 18 for limiting the relative position of the ear seat 17 and the hanging rod 5 is connected to the second threaded hole on the side of the ear seat 17 away from the band saw shell 1. The position of the hanging rod 5 is adjusted along the rectangular opening on the ear seat 17. At this time, the height of the lifting seat 6 changes, that is, the relative position of the rolling bearing 9 and the band saw blade 2 changes, so as to adjust the distance between the rolling bearing 9 and the processing table 11 according to the size of the filter element.

[0027] See Figures 1-4The lifting seat 6 has two guide holes 24 on the side facing the band saw blade 2, and studs 8 are inserted into each guide hole 24.

A limiting nut 16, threadedly connected to the stud 8, is provided on the side of the rolling bearing 9 away from the end plate 10, so that the outer rings of the two rolling bearings 9 contact the two sides of the band saw blade 2 respectively. When the band saw blade 2 rotates around the upper pulley 3 and the lower pulley 12 under the drive of the motor 19, the band saw... The band saw blade 2 will cause the outer ring of the rolling bearing 9 to rotate. On the one hand, the two rolling bearings 9 work together to support the band saw blade 2. On the other hand, when the outer ring of the rolling bearing 9 is worn and no longer in contact with the band saw blade 2, the outer ring of the rolling bearing 9 will stop rotating, thus providing an indication that the band saw blade 2 has lost support. This allows personnel to stop the machine in time to replace the rolling bearing 9, reducing the probability of the band saw blade 2 being damaged by unbalanced forces. Adjust the position of the stud 8 along the guide hole 24. At this time, the relative position of the rolling bearing 9 and the band saw blade 2 changes. When the worn area of ​​the outer ring of the rolling bearing 9 is misaligned with the band saw blade 2, the relative position of the stud 8 and the lifting seat 6 can be restricted by the first positioning screw 7, which helps to improve the utilization rate of the rolling bearing 9.
