Technical Field

[0001] The utility model relates to the technical field of filter processing, in particular to a semi-automatic cutting mechanism for processing filter elements of filters. Background Art

[0002] A filter is a component that filters impurities or gases through a filter paper. Generally, it refers to an automotive filter, which is a component of an engine. As Figure 4 shown, it is a semi-automatic cutting mechanism used in the processing of the previous generation of filter elements. Its main function is to cut a long folded filter paper into multiple segments at a fixed length, so as to facilitate the subsequent processing operations of the filter element.

[0003] However, the previous generation of semi-automatic cutting mechanisms for processing filter elements of filters has the following deficiencies in actual use: when cutting and processing the filter paper, the operator needs to manually clamp and fix the filter paper on the feeding table in advance, and then use his hand to push the feeding table upward in the longitudinal sliding groove of the cutting table, and push the filter paper horizontally backward onto the rotating cutting knife to achieve the fixed-length cutting operation of the filter paper. The entire clamping and cutting process requires the operator to directly participate manually, which not only reduces the efficiency and convenience of filter paper cutting and processing, but also the operator's limbs are easily in contact with the cutting knife during the entire filter paper cutting operation, resulting in certain safety hazards during the cutting process.

[0004] In view of this, it is particularly important to design and manufacture a semi-automatic cutting mechanism that can improve the efficiency and convenience of filter paper cutting and processing, and at the same time reduce the safety hazards of the actual operation of the operator, and apply it in the process of processing filter elements of filters. Content of the Utility Model

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-4, the present utility model provides a technical solution: a semi-automatic cutting mechanism for processing filter element, including a cutting table 1, a cutting machine 2 installed at the lower end of the cutting table 1, a cutting knife 201 detachably installed at the left end of the cutting machine 2 and penetrating upward through the cutting table 1, a longitudinal chute 101 installed at the upper end of the cutting table 1 and on the right side of the cutting knife 201, and a feeding table 3 movably installed at the upper end of the longitudinal chute 101. A clamping part for automatically clamping and fixing the filter paper on the feeding table 3 is arranged on the feeding table 3. A driving part for cooperating with the clamping part to drive the filter paper on the feeding table 3 to automatically slide longitudinally and contact the cutting knife 201 is arranged between the cutting table 1 and the feeding table 3.

[0030] Specifically, as Figures 1-3 shown, the clamping part includes two electric oil cylinders 4 symmetrically fixed at the middle parts of the front end and the rear end of the feeding table 3, and C-shaped clamping pieces 401 installed on the telescopic ends of the two electric oil cylinders 4 and buckling with the feeding table 3.

[0031] Specifically, as Figures 1-3 shown, the driving part includes a limit sliding hole 103 opened on the cutting table 1 and on the right side of the longitudinal chute 101, a limit sliding block 301 fixed at the middle part of the right end of the feeding table 3 and inside the limit sliding hole 103, a stepping motor 5 installed at the lower end of the limit sliding block 301, a transmission gear 501 installed at the upper end of the stepping motor 5, and a transmission rack 6 installed on the right side of the limit sliding hole 103 and meshing with the transmission gear 501. The stepping motor 5 can drive the transmission gear 501 to rotate clockwise or counterclockwise. Under the meshing transmission action between the transmission gear 501 and the transmission rack 6, the feeding table 3 can move longitudinally backward or forward in the longitudinal chute 101 on the cutting table 1.

[0032] Specifically, as Figures 1-3 shown, a position sensor 7 facing the feeding table 3 is installed at the middle part of the rear side of the upper end of the cutting table 1, a microcomputer controller 8 is installed at the front side of the upper end of the cutting table 1, a display screen 801 and control buttons 802 are installed on the microcomputer controller 8. The display screen 801 can display the working parameters of the cutting mechanism and the count display of the cutting cycle, which is convenient for the operator to understand the working state of the cutting mechanism and the number of cuttings. Among them, the output ends of the position sensor 7 and the control buttons 802 are respectively electrically connected to the input end of the microcomputer controller 8, and the output end of the microcomputer controller 8 is respectively electrically connected to the input ends of the cutting machine 2, the electric oil cylinders 4 and the stepping motor 5. The position sensor 7 can collect the position of the feeding table 3 on the cutting table 1 in real time and transmit the position data of the feeding table 3 to the microcomputer controller 8 in real time for calculation, comparison and analysis. The microcomputer controller 8 can then control the cutting machine 2, the electric oil cylinders 4 and the stepping motor 5 to perform corresponding operations. At the same time, the operator can control the power-on of the cutting machine 2, the electric oil cylinders 4 and the stepping motor 5 and set the working parameters by operating the control buttons 802.

[0033] Specifically, as Figures 1-3 shown, a protective retaining frame 102 is installed at the upper end of the cutting table 1 where the upper end of the cutting knife 201 is located, which can protect the upper part of the cutting knife 201 to prevent the operator's limbs from touching the upper half of the cutting knife 201. A protective cover 105 covering the cutting knife 201 is installed at the lower end of the cutting table 1, which can protect the lower part of the cutting knife 201 to prevent the operator's limbs from touching the lower half of the cutting knife 201. Mounting holes 104 are provided at the four corners of the upper end of the cutting table 1, facilitating the installation and fixation operation of the cutting table 1 through fasteners.

[0034] Working principle: During use, the cutting table 1 can be installed and fixed to the cutting station of the filter element processing equipment through the mounting holes 104, and then the control circuit of the semi-automatic cutting mechanism is connected to the control terminal of the filter element processing equipment, thus completing the assembly operation of the semi-automatic cutting mechanism. During the actual processing, the operator can adjust and place the filter paper between the feeding table 3 and the two C-shaped clamping pieces 401, and then can operate the control button 802 on the microcomputer controller 8 to control the two electric oil cylinders 4 to extend outward synchronously. At this time, the two C-shaped clamping pieces 401 can move inward synchronously to automatically center and clamp the filter paper on the feeding table 3. After the filter paper is clamped, the operator can continue to operate the control button 802 on the microcomputer controller 8 to control the stepping motor 5 and the cutting machine 2 to be powered on and work. The stepping motor 5 can drive the transmission gear 501 to rotate clockwise. Under the meshing transmission between the transmission gear 501 and the transmission rack 6, the whole feeding table 3 can move backward. At the same time, the cutting machine 2 can drive the cutting knife 201 to rotate to cut the filter paper moving backward on the feeding table 3. When the feeding table 3 moves to the rearmost end of the longitudinal sliding groove 101, a single cutting operation is completed. The position sensor 7 will detect that the feeding table 3 has moved backward to the maximum stroke, and thus transmit the position data to the microcomputer controller 8. After calculating, comparing and analyzing the position data, the microcomputer controller 8 can control the cutting machine 2 to stop being powered on, the stepping motor 5 to rotate counterclockwise, and the electric oil cylinder 4 to contract inward. At this time, the feeding table 3 can move forward to reset to the initial position to facilitate the subsequent cutting and processing operation of the filter paper.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, making equivalent replacements or changes should be covered within the protection scope of the present invention.
