Technical Field
[0001] This utility model belongs to the field of filter technology, and in particular relates to an automatic cutting device for the production of primary filters. Background Technology
[0002] A pre-filter is a common type of air filter, typically used to filter large particles in the air, such as dust, hair, and pet dander. It is usually installed at the air inlet of air handling equipment or air conditioning systems to protect other filters and extend their lifespan.
[0003] The most important part of a pre-filter is naturally the filter screen located at the center of the filter. When the filter screen is cut, a cutter is used. However, since most existing filter screens are made of plastic, the frictional heat generated when the cutter comes into contact with the filter screen and the heat generated during the cutting process cannot be dissipated in time. This causes the filter screen fragments to melt and adhere to the cutter, which affects the cutting effect of the filter screen. As a result, the filter screen may remain connected and not be fully separated when it is cut later.
[0004] Therefore, how to provide an automatic cutting device for the production of primary filters is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram shown is a structural schematic of an automatic cutting device for producing primary filters according to an embodiment of the present invention, comprising:
[0029] Cropping platform 1;
[0030] The second support plate 17 is symmetrically installed on the top of the left end of the cutting platform 1;
[0031] The lifting structure is located at the right end of the second support plate 17, and the bottom side is movably connected to the cutter 5.
[0032] The reciprocating cleaning structure is located in the middle of the right end of the second support plate 17 and is attached to the surface of the cutter 5 to clean the working surface of the cutter 5.
[0033] In this embodiment of the utility model, when in use, the lifting structure is activated, causing the cutter 5 to rise and fall, and the reciprocating cleaning structure to change the workpiece angle as the cutter 5 rises and falls, thereby cleaning the working surface of the cutter 5.
[0034] By setting a reciprocating cleaning structure on the second support plate 17 that can change the working angle as the cutter 5 rises and falls, the working surface of the cutter 5 can be cleaned after each rise, thereby reducing the presence of residual debris on its surface, maintaining the sharpness of the cutter 5, and thus extending its continuous working time, service life, and cleaning difficulty.
[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, a cooling and impurity suction structure is also provided on the second support plate 17. The cooling and impurity suction structure includes a filter box 15 and a blower plate 13. The filter box 15 is symmetrically arranged on the outer side of the second support plate 17 at both the front and rear ends, and a fan 16 is fixedly installed at the bottom. The blower plate 13 is arranged at the lower end of the reciprocating cleaning structure, and the lower end is bent to face the side of the cutter 5. An exhaust pipe 14 is provided between the side of the upper end of the blower plate 13 and the filter box 15.
[0036] In this embodiment of the utility model, when in use, the fan 16 is started. Through the cooperation of the filter box 15, the exhaust pipe 14 and the blower plate 13, the air around the cutter 5 flows when the cutter 5 rises, which in turn causes the surface temperature of the cutter 5 to drop rapidly, and the debris remaining on its surface to solidify rapidly.
[0037] By setting up a cooling and waste-collecting structure, residual debris on the surface of the cutter 5 can be quickly solidified, and debris generated during cleaning can be collected, reducing the trouble caused by later cleaning.
[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4and Figure 5 As shown, in a preferred embodiment of this utility model, the reciprocating cleaning structure includes a movable groove 6, a reciprocating telescopic motor 7, a reciprocating traction plate 8, a lifting rod 9, a spring 10, and a scraper 12. The movable groove 6 is symmetrically opened on the inner side of the second support plate 17 at both the front and rear ends. The reciprocating telescopic motor 7 is fixedly installed at the inner end of the movable groove 6. The reciprocating traction plate 8 is movably installed on the surface of the reciprocating telescopic motor 7, and its middle side is attached to the upper end of the cutter 5. The lifting rod 9 is arrayed and hinged to the surface of the reciprocating traction plate 8, and a first support plate 11 is fixedly installed at the bottom. The scraper 12 is fixedly installed at the bottom of the first support plate 11 and is attached to the bottom end of the cutter 5. The spring 10 is movably sleeved on the upper end of the lifting rod 9 and fixedly connected to the top of the reciprocating traction plate 8. A blower plate 13 is fixedly installed on the outer side of the bottom of the first support plate 11.
[0039] In this embodiment of the utility model, when the reciprocating telescopic motor 7 in the active slot 6 is started, the reciprocating traction plate 8 moves back and forth, and then the lifting rod 9 hinged to its surface drives the scraper plate 12 to reciprocate and rub, thereby allowing the solidified debris on the surface of the cutter 5 to be quickly rubbed into powder and removed.
[0040] By setting up the cooperation between the lifting rod 9 and the spring 10, and by hinged the array of lifting rod 9 to the surface of the reciprocating traction plate 8, the working angle of the scraper plate 12 can be changed according to the cutter 5, thereby achieving a better cleaning effect.
[0041] like Figure 1 and Figure 4 As shown, in a preferred embodiment of the present invention, the lifting structure includes a support rod 2, a telescopic rod 3, a positioning plate 4, and a cutter 5. The support rod 2 is fixedly installed on the upper end of the right side of the second support plate 17, the telescopic rod 3 is arrayed and installed on the surface of the support rod 2, the positioning plate 4 is fixedly installed on the bottom of the telescopic rod 3, and the cutter 5 is movably installed on the right side of the positioning plate 4.
[0042] In this embodiment of the utility model, when in use, the telescopic rod 3 on the support rod 2 is activated, which in turn drives the cutter 5 to cut the filter screen through the positioning plate 4 at its bottom, and then the cutter 5 is reset.
[0043] By setting up a lifting structure, the lifting height of the cutter 5 can be determined, which facilitates the cutting of the filter screen.
[0044] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, a material roller 18 is movably installed on the top left side of the cutting platform 1, a material discharge groove 19 is opened on the right side of the cutting platform 1, and a transmission roller 20 is movably installed on the bottom left end of the second support plate 17.
[0045] In this embodiment of the utility model, when in use, a material roller 18 is movably installed on the top left side of the cutting platform 1, a feeding trough 19 is opened on the right side of the cutting platform 1, and a transmission roller 20 is movably installed on the bottom left end of the second support plate 17, so as to facilitate the determination and guidance of the cutting length of the material roller 18, and facilitate the subsequent collection.
[0046] like Figure 1 and Figure 4 As shown, in a preferred embodiment of this utility model, the length of the scraper 12 is less than the length of the cutter 5, and the length of the reciprocating traction plate 8 is greater than the length of the cutter 5.
[0047] In this embodiment of the invention, when in use, by making the length of the scraper 12 less than the length of the cutter 5 and the length of the reciprocating traction plate 8 greater than the length of the cutter 5, the reciprocating traction plate 8 can easily drive the scraper 12 to perform reciprocating cleaning on the surface of the cutter 5.
[0048] like Figure 2 and Figure 5 As shown, in a preferred embodiment of the present invention, a through groove 21 is provided in the middle of the reciprocating traction plate 8, and the thickness of the through groove 21 is the same as the thickness of the cutter 5.
[0049] In this embodiment of the utility model, when in use, a through groove 21 is provided in the middle of the reciprocating traction plate 8, and the thickness of the through groove 21 is the same as the thickness of the cutter 5, thereby facilitating the lifting and lowering of the cutter 5 and the reciprocating movement of the reciprocating traction plate 8.
[0050] The above embodiments of this utility model provide an automatic cutting device for the production of primary filters. When in use, the material roller 18 is placed on the top left side of the cutting platform 1, and then one end of the filter screen on the surface of the material roller 18 is placed below the transmission roller 20. Then, under the drive of the transmission roller 20, the filter screen enters the feeding trough 19.
[0051] After moving to the required length, the telescopic rod 3 on the support rod 2 is activated, which in turn drives the cutter 5 to cut the filter screen through the positioning plate 4 at its bottom. Then the cutter 5 is reset.
[0052] When the cutter 5 descends, it will press the scraper 12 on the inner side of the first support plate 11 at the bottom of the lifting rod 9, so that the scraper 12 moves to both sides as the cutter 5 descends, thus facilitating the cutting of the cutter 5.
[0053] Then the fan 16 is started. Through the cooperation of the filter box 15, the exhaust pipe 14 and the blower plate 13, the air around the cutter 5 flows when the cutter 5 rises, which in turn causes the surface temperature of the cutter 5 to drop rapidly, and the debris remaining on its surface to solidify quickly.
[0054] At the same time, when the cutter 5 rises, under the action of the spring 10 at the upper end of the lifting rod 9, the scraper 12 moves along the working surface of the cutter 5 to the center as the cutter 5 rises, thereby causing the scraper 12 to rub against the working surface of the cutter 5. At the same time, the reciprocating telescopic motor 7 in the movable slot 6 is activated, causing the reciprocating traction plate 8 to move back and forth. Then, through the lifting rod 9 hinged to its surface, the scraper 12 is driven to rub back and forth, thereby allowing the solidified debris on the surface of the cutter 5 to be quickly rubbed into powder and removed.
[0055] The debris is then absorbed into the filter bin 15 by the working blower plate 13 for filtration and storage, thereby preventing debris from falling onto the filter screen and causing the filter screen surface to become contaminated.
[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
