Description

Technical Field

[0001] This utility model relates to the field of filter element frame processing, and in particular to a filter element frame fixed-distance cutting device. Background Technology

[0002] In the field of filtration technology, filter elements are classified according to their functions, including water treatment filter elements, air purification filter elements, and oil filtration filter elements. Most common filter elements are made of flexible filter materials. Although these materials have good filtration efficiency and dirt holding capacity, their mechanical strength is low. Therefore, the outer ring of the filter element usually needs to be equipped with a rigid support structure to maintain morphological stability. Among them, perforated steel tubes have become a commonly used material for industrial filter element skeletons because they have both rigid support and fluid channel functions.

[0003] In the existing filter element frame manufacturing process, the perforated steel pipe needs to be cut at fixed intervals according to the filter element design length. Traditional cutting equipment uses manual marking of positioning points combined with mechanical cutting wheels to cut the steel pipe. Operators mark the cutting positions on the surface of the steel pipe according to process requirements, then fix the steel pipe to the cutting platform, and use hydraulic or electric drive to drive the cutting wheel to cut along the marked lines.

[0004] Currently, during the cutting process, the manual marking process relies on the operator's experience. The marking lines are prone to deviation due to visual errors or stains on the steel pipe surface, resulting in the cutting length not matching the actual requirements. The manual material handling and marking operations also slow down the production cycle. Utility Model Content

[0005] To overcome the shortcomings of manual positioning errors, this utility model provides a filter element frame spacing cutting device, which aims to solve the above-mentioned shortcomings.

[0006] A filter cartridge frame fixed-distance cutting device includes a frame. Several rotating shafts are rotatably connected to the front and rear sides of the upper part of the frame. The rotating shafts are inclined. The bottom of the rotating shafts on both sides are close to each other and connected to a bevel gear set. A motor is installed on the top of the frame and connected to the top of the rotating shaft. A sprocket is connected to the upper end of each rotating shaft. A chain is installed inside the frame and meshes with all the sprockets on the same side. A cutter for cutting steel is installed on the top right end of the frame. A fixed-distance component for adjusting the cutting distance is provided on the right end of the frame.

[0007] Optionally, the distance fixing component includes a distance fixing frame located on the right side of the frame. Both ends of the frame are rotatably connected to lead screws. The right end of each lead screw is rotatably connected to the distance fixing frame. The right ends of the two lead screws are fitted with a belt. The right end of the distance fixing frame is rotatably connected to a handwheel, which is connected to the end of the lead screw.

[0008] Optionally, a cylinder is installed at the top right end of the frame. An extension plate is connected to the bottom of the piston rod of the cylinder. Two guide rods are slidably connected to the bottom left of the extension plate. An elastic band is connected to the bottom of the two guide rods. A spring is sleeved on the guide rod. The bottom of the spring is slidably connected to the connecting blocks at both ends of the elastic band. The top of the spring is connected to the extension plate of the cylinder.

[0009] Optionally, a scale is connected to the left end of the spacer, and the scale is slidably connected inside the frame.

[0010] Optionally, the bottom of the spacer frame is equipped with casters.

[0011] Optionally, the handwheel sleeve is provided with an anti-slip sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. Through the cooperation of the spacer, lead screw, and belt, the lead screw rotates to drive the spacer to move horizontally, and the belt ensures that the lead screws on both sides rotate synchronously, so as to achieve precise adjustment of the cutting length and reduce the error of manual measurement.

[0014] 2. By cooperating with the pressure sensor on the spacer frame and the controller, the controller automatically shuts off the motor and starts the cylinder when the end of the steel material contacts the sensor, thereby achieving coordinated control of stopping and clamping, and avoiding manual marking deviation.

[0015] 3. Through the cooperation of cylinder, elastic band, guide rod and spring, when the cylinder pushes the elastic band down, the guide rod guides the direction of movement, and the spring buffers the pressure so that the elastic band and the rotating shaft form an elastic clamp, so as to fix the steel and avoid damaging the surface.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0021] Example: A filter cartridge frame spacer cutting device, such as... Figures 1-3 As shown, the machine includes a frame 1, a motor 2, sprockets 3, chains 4, rotating shafts 5, bevel gear sets 6, a distance fixing component, and a cutter 14. Several rotating shafts 5 are rotatably connected to the front and rear sides of the upper part of the frame 1. The rotating shafts 5 are inclined. The rotating shafts 5 on both sides are driven by the bevel gear sets 6 at the bottom to achieve reverse rotation. The bevel gear sets 6 ensure that the rotating shafts 5 on both sides rotate in opposite directions, so that the steel moves smoothly towards the distance fixing frame 7. The motor 2 is installed on the top of the frame 1. The motor 2 is connected to the top of the rotating shaft 5. The upper end of the rotating shaft 5 is connected to a sprocket 3. A chain 4 is installed inside the frame 1. The chain 4 is engaged with all the sprockets 3 on the same side. The sprockets 3 are driven by the chain 4 to ensure that the rotating shafts 5 on the same side rotate synchronously. A cutter 14 for cutting steel is installed on the top right end of the frame 1. A distance fixing component for adjusting the cutting distance is set on the right end of the frame 1.

[0022] like Figure 1 and Figure 2 As shown, the distance fixing assembly includes a distance fixing frame 7, lead screws 8, belts 9 and handwheels 10. The distance fixing frame 7 is located on the right side of the frame 1. Lead screws 8 are rotatably connected to both ends of the frame 1. The right end of the lead screws 8 is rotatably connected to the distance fixing frame 7. The right ends of the two lead screws 8 are fitted with belts 9. The belt 9 drives the lead screws 8 on both sides to rotate synchronously, driving the distance fixing frame 7 to move horizontally and accurately adjust the distance to the right end of the frame 1. The right end of the distance fixing frame 7 is rotatably connected to the handwheel 10, which is connected to the end of the lead screws 8.

[0023] like Figure 1 As shown, it also includes a cylinder 11, an elastic band 12, a guide rod 121, and a spring 13. The cylinder 11 is installed on the top right end of the frame 1. The piston rod of the cylinder 11 is connected to an extension plate at the bottom. Two guide rods 121 are slidably connected to the bottom left of the extension plate. The bottom of the two guide rods 121 are connected to the elastic band 12. The guide rods 121 are fitted with springs 13. The bottom of the spring 13 is slidably connected to the connecting blocks at both ends of the elastic band 12. The top of the spring 13 is connected to the extension plate of the cylinder 11. The elastic band 12 and the rotating shaft 5 form an elastic clamp, which fixes the steel while avoiding damage to the surface.

[0024] like Figure 2 As shown, it also includes a ruler 15. The left end of the spacer 7 is connected to the ruler 15. The ruler 15 is slidably connected inside the frame 1. The ruler 15 moves with the spacer 7 to intuitively display the cutting length setting value.

[0025] like Figure 1 As shown, it also includes casters 16. Casters 16 are installed at the bottom of the spacer frame 7. The casters 16 roll when the spacer frame 7 moves, making the adjustment process smoother.

[0026] like Figure 2 As shown, it also includes an anti-slip sleeve 17. The handwheel 10 is fitted with an anti-slip sleeve 17, which increases the surface friction of the handwheel 10, making it easier for staff to hold and operate.

[0027] The worker places the steel horizontally on top of the frame 1. The inclined rotating shafts 5 on both sides provide support to the steel through surface contact, while the inclination angle of the shafts 5 creates an inclined plane to restrict the steel's lateral rolling. After starting the motor 2, the motor 2 drives one of the rotating shafts 5 to rotate. The sprocket 3 at the top of this rotating shaft 5 drives all the shafts on the same side via a chain 4, causing them to rotate synchronously and thus driving all the rotating shafts 5 on that side to rotate in the same direction. The rotating shaft 5 on the other side is connected to the front rotating shaft 5 via a bevel gear set 6 at its bottom, achieving reverse rotation. The difference in the rotation direction of the two rotating shafts 5 causes the steel to move smoothly towards the spacer 7 under the action of friction. When the end of the steel contacts the pressure sensor installed on the spacer 7, the controller receives the pressure signal and cuts off the power to the motor 2, while simultaneously activating the cylinder 11. The piston rod of cylinder 11 pushes the extension plate down, which drives the guide rod 121 and elastic band 12 to press down synchronously. After the elastic band 12 contacts the steel surface, it undergoes elastic deformation and forms a clamping force with the rotating shaft 5 below to fix the steel. At this time, the cutter 14 performs the cutting action. The cut steel segment falls naturally into the collection area through the gap between the frame 1 and the spacer 7, completing the quantitative cutting.

[0028] To adjust the cutting length, the operator holds the anti-slip sleeve 17 on the surface of the handwheel 10 and rotates it, causing the lead screw 8 to rotate. The lead screw 8, in its threaded engagement with the frame 1, generates axial displacement, driving the spacer frame 7 to move horizontally along the direction of the steel material. The lead screws 8 on both sides rotate synchronously via belt 9, ensuring that the spacer frame 7 remains horizontal during movement. The bottom caster wheel 16 rolls with the spacer frame 7 to reduce sliding friction. During movement, the current cutting length setting is visually displayed by the change in the relative position of the scale 15 on the left side of the spacer frame 7 and the frame 1. After adjustment, the position of the lead screw 8 is fixed by the locking device, thus achieving precise adjustment of the cutting length.
