Description

[0002] During the production process of the filter element, it is necessary to glue the side strips to the filter element. In the actual glueing process, the length of the strips glued to the side of the filter element is longer than the filter element.

However, referring to Figure 1 and Figure 7 For the filter element 7 with the right-angled edge strip 11, when the existing edge trimming machine or edge trimming equipment is used to trim the right-angled edge strip 11, the movable knife 9 will squeeze the horizontal edge 13 of the right-angled edge strip 11 when cutting the right-angled edge strip 11 directly toward the fixed knife 8, causing the horizontal edge 13 of the right-angled edge strip 11 to bend or warp, resulting in an uneven cut or cutting failure.

Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0036] In one embodiment of the present invention, referring to Figures 1-6 , provides a filter element trimming mechanism 200, including a mounting seat 210, a fixed knife 220, a movable knife 230 and a first driving member 240.

[0037] Among them, reference Figure 2 and Figure 3 The fixed knife 220 is disposed on the mounting seat 210 , and the movable knife 230 is movably disposed on the mounting seat 210 and is arranged opposite to the fixed knife 220 , and a shearing position 250 is formed between the movable knife 230 and the fixed knife 220 .

[0038] Among them, reference Figure 2 and Figure 3 The movable knife 230 is provided with a first blade 231 and a second blade 232 connected to each other, and the angle a between the first blade 231 and the second blade 232 is an obtuse angle.

[0039] Among them, reference Figure 2 and Figure 3The first driving member 240 is provided on the mounting seat 210. The first driving member 240 is used to drive the movable knife 230 to move back and forth, and is used to cut the vertical edge 12 of the right-angled edge strip 11 of the filter element 10 when the first blade 231 cooperates with the fixed knife 220, and is used to cut the horizontal edge 13 of the right-angled edge strip 11 of the filter element 10 when the second blade 232 cooperates with the fixed knife 220.

[0040] Compared with the prior art, the one or more technical solutions in the filter element trimming mechanism 200 provided in the embodiment of the present invention have at least one of the following technical effects:

[0041] Reference Figure 2 and Figure 3 When trimming, first place the excess (overlong) right-angled edge strip 11 of the filter element 10 in the shearing position 250, and then the first driving member 240 drives the movable knife 230 to move toward the fixed knife 220, and the first blade 231 cooperates with the fixed knife 220 to shear the vertical edge 12 of the right-angled edge strip 11 of the filter element 10, and the second blade 232 cooperates with the fixed knife 220 to shear the horizontal edge 13 of the right-angled edge strip 11 of the filter element 10. The first blade 231 cooperates with the fixed knife 220 and the second blade 232 cooperates with the fixed knife 220 to shear the vertical edge 12 and horizontal edge 13 of the right-angled edge strip 11 of the filter element 10 respectively, similar to the shearing method of scissors, so that the cut of the right-angled edge strip 11 is smooth and flush with the side wall of the filter element 10, thereby ensuring the trimming quality of the filter element 10.

[0042] In addition, a power source is used to complete the shearing of the excess right-angled edge strips 11 on the side of the filter element 10 at one time. Compared with the method of using personnel to shear the right-angled edge strips 11, it is safer, has high cutting efficiency, and has low processing costs.

[0043] In another embodiment of the present invention, referring to Figure 2 and Figure 3 The fixed blade 220 is provided with a connected vertical blade 221 and a horizontal blade 222. When the first blade 231 cooperates with the vertical blade 221, it is used to cut the vertical edge 12 of the right-angled edge strip 11 of the filter element 10. When the second blade 232 cooperates with the horizontal blade 222, it is used to cut the horizontal edge 13 of the right-angled edge strip 11 of the filter element 10. The first blade 231 cooperates with the vertical blade 221, and the second blade 232 cooperates with the horizontal blade 222 to respectively cut the vertical edge 12 and horizontal edge 13 of the right-angled edge strip 11 of the filter element 10, similar to the cutting method of scissors. This ensures a smooth cut on the right-angled edge strip 11 and ensures the quality of the cut edge of the filter element 10.

[0044] In a specific embodiment, referring to Figure 2 and Figure 3The first blade 231 and the second blade 232 are both inclined. The angle b between the first blade 231 and the vertical blade 221 is an acute angle. When the first driving member 240 drives the first blade 231 toward the vertical blade 221, it will first cut the vertical edge 12 of the right-angled side strip 11 from the top along the vertical edge 12 downward, similar to using scissors to cut from the top to the bottom of the vertical edge 12, so that the cut of the vertical edge 12 is smooth. The angle c between the second blade 232 and the horizontal blade 222 is an acute angle. When the first driving member 240 drives the second blade 232 toward the horizontal blade 222, it will first cut the horizontal edge 13 from one end of the horizontal edge 13 of the right-angled side strip 11 along the horizontal edge 13 to the other end, similar to using scissors to cut from one end of the horizontal edge 13 to the other end, so that the cut of the horizontal edge 13 is smooth.

[0045] Preferably, refer to Figure 2 and Figure 3 The included angle b between the first blade 231 and the vertical blade 221 is ≥ 0° and < 45°. Therefore, when the first blade 231 contacts and shears the vertical side 12 of the right-angled side strip 11, the horizontal component of the force acting on the vertical side 12 is greater than the vertical component, which is conducive to shearing the vertical side 12. The included angle c between the second blade 232 and the horizontal blade 222 is greater than 0° and < 45°. Therefore, when the second blade 232 contacts and shears the horizontal side 13 of the right-angled side strip 11, the vertical component of the force acting on the horizontal side 13 is greater than the horizontal component, which is conducive to shearing the horizontal side 13.

[0046] In another embodiment of the present invention, referring to Figure 2 and Figure 3 The filter element trimming mechanism 200 also includes a pushing assembly 260. The pushing assembly 260 includes a second driving member 261 and a pushing plate 262. The second driving member 261 is provided on the mounting seat 210, and the pushing plate 262 is provided on the second driving member 261. The pushing plate 262 is located next to the fixed knife 220. The second driving member 261 drives the pushing plate 262 to move, which is used to push off the extra right-angled edge strips 11 that have been cut off, and prevent the right-angled edge strips 11 that have been cut off from adhering to the fixed knife 220, thereby ensuring that the filter element trimming mechanism 200 stably shears the right-angled edge strips 11 of the filter element 10. Specifically, the second driving member 261 is a second cylinder, and the telescopic rod of the second cylinder is connected to the pushing plate 262. The pushing plate 262 is driven to reciprocate by the telescopic movement of the second cylinder, thereby being used to push off the extra right-angled edge strips 11 that have been cut off, and the structure is simple.

[0047] Further, refer to Figure 2 and Figure 3The mounting seat 210 is provided with an inclined blanking guide plate 270 next to the shearing position 250. The excess right-angled edge strips 11 that are cut off fall onto the blanking guide plate. The inclined blanking guide plate 270 is used to guide the excess right-angled edge strips 11 that are cut off for collection and guide the excess right-angled edge strips 11 that are cut off to a designated position for collection so as to be processed centrally.

[0048] Further, refer to Figure 2 and Figure 3 The mounting base 210 is provided with at least one linear guide rail 211, and a mounting frame 212 is slidably connected to the linear guide rail 211 via at least one slider. A movable blade 230 is mounted on the mounting frame 212. A first driving member 240 is connected to the mounting frame 212 and is used to drive the movable blade 230 to reciprocate along the linear guide rail 211, ensuring smooth movement of the movable blade 230 for precise cutting of the right-angled edge strip 11. Specifically, the first driving member 240 is a first pneumatic cylinder, the telescopic rod of which is connected to the mounting frame 212. The telescopic movement of the first cylinder drives the mounting frame 212 to reciprocate along the linear guide rail 211, thereby driving the movable blade 230 to reciprocate along the linear guide rail 211, resulting in a simple structure.

[0049] Specifically, refer to Figure 2 and Figure 3 The movable blade 230 is fixed to the mounting bracket 212 by a plurality of screws, and the fixed blade 220 is fixed to the mounting base 210 by a plurality of screws.

[0050] In another embodiment of the present invention, referring to Figure 2 、 Figure 4 and Figure 5 A filter element trimming device is also provided, comprising a bracket 100 and four sets of the aforementioned filter element trimming mechanisms 200. The four sets of filter element trimming mechanisms 200 are mounted on the bracket 100 and are respectively used to trim excess right-angled edge strips 11 at the four corners of the filter element 10. This allows for a complete shearing of the excess right-angled edge strips 11 at the four corners of the filter element 10 at one time, resulting in high trimming efficiency and low processing costs.

[0051] Among them, reference Figure 4 and Figure 5 The bracket 100 is provided with a first X-axis transfer mechanism 110, which is equipped with four sets of first Y-axis transfer mechanisms 120. Four sets of filter element trimming mechanisms 200 are respectively mounted on the four sets of first Y-axis transfer mechanisms 120. The first X-axis transfer mechanism 110 and the four sets of first Y-axis transfer mechanisms 120 drive the four sets of filter element trimming mechanisms 200 to move, adjusting the spacing between adjacent sets of the four sets of filter element trimming mechanisms 200 to accommodate filter elements 10 of different sizes, thus providing extremely high practicality.

[0052] In a specific embodiment, referring to Figure 4 and Figure 5 The first X-axis transfer mechanism 110 includes two first linear guide rails 111, a first screw rod 112, a second screw rod 113, two first X-axis transfer plates 114, and a first motor 115. The two first linear guide rails 111 are symmetrically arranged on the bracket 100, and the two first X-axis transfer plates 114 are slidably connected to the two first linear guide rails 111 via a plurality of first sliding blocks. One end of the first screw rod 112 is fixedly connected to one end of the second screw rod 113, and the other end of the first screw rod 112 and the other end of the second screw rod 113 are respectively rotatably connected to the bracket 100 via bearing seats. The screw threads of the first screw rod 112 and the second screw rod 113 have opposite spiral directions. The first screw rod 112 and the second screw rod 113 are both connected to screw nuts, and the two screw nuts are respectively fixedly connected to the two first X-axis transfer plates 114. Two sets of first Y-axis transfer mechanisms 120 are installed on each first X-axis transfer plate 114. The first motor 115 is installed on the bracket 100. The rotating shaft of the first motor 115 is fixedly connected to one end of the first screw rod 112. The first motor 115 drives the first screw rod 112 and the second screw rod 113 to rotate, driving the two first X-direction moving plates 114 to move closer to or away from each other, thereby driving one or two groups of filter element trimming mechanisms 200 and the other two groups of filter element trimming mechanisms 200 to move closer to or away from each other, thereby realizing spacing adjustment.

[0053] In a specific embodiment, referring to Figure 4 and Figure 5 The first Y-direction transfer mechanism 120 is a first linear module. The mounting seat 210 of each filter element trimming mechanism 200 is fixedly mounted on a moving block of the first linear module. The filter element trimming mechanism 200 is driven to move along the Y-direction by the first linear module, thereby adjusting the distance between the two groups of filter element trimming mechanisms 200 located on the first X-direction transfer plate 114 to achieve distance adjustment.

[0054] Further, refer to Figure 4 and Figure 6The bracket 100 is provided with a second Y-direction transfer mechanism 130 above the filter element trimming mechanism 200, and a Z-direction transfer mechanism 140 is provided on the second Y-direction transfer mechanism 130. The Z-direction transfer mechanism 140 is provided with a connecting frame 150, and a loading mechanism 160 is provided on the connecting frame 150, or a loading mechanism 160 and a unloading mechanism 170 are provided at intervals. The loading mechanism 160 is used to clamp the filter element 10 to be trimmed, and the second Y-direction transfer mechanism 130 and the Z-direction transfer mechanism 140 are used to drive the loading mechanism 160 to move so as to transfer the filter element 10 to be trimmed to between the four groups of filter element trimming mechanisms 200. There is no need for personnel to load the filter element 10, which greatly improves production efficiency and reduces processing costs. Among them, the unloading mechanism 170 is used to clamp the filter element 10 with completed trimming, and the second Y-axis transfer mechanism 130 and the Z-axis transfer mechanism 140 are used to drive the unloading mechanism 170 to move to move the filter element 10 with completed trimming out of the four groups of filter element trimming mechanisms 200. There is no need for personnel to unload the material (filter element 10), which greatly improves production efficiency and reduces processing costs.

[0055] Specifically, refer to Figure 4 and Figure 6 The second Y-direction transfer mechanism 130 is a second linear module, and the Z-direction transfer mechanism 140 is installed on the moving block of the second linear module. The Z-direction transfer mechanism 140 is driven by the second linear module to move in the Y direction, thereby driving the loading mechanism 160 and the unloading mechanism 170 to move in the Y direction. The Z-direction transfer mechanism 140 includes a Z-direction cylinder 141 and a guide rod 142. The Z-direction cylinder 141 is installed on the moving block of the second linear module, and the connecting frame 150 is fixed on the driving rod of the Z-direction cylinder 141. The loading mechanism 160 and the unloading mechanism 170 are driven to move in the Z direction by the Z-direction cylinder 141. The lower end of the guide rod 142 is fixedly connected to the connecting frame 150, and the guide rod 142 is slidably connected to the moving block of the second linear module through the guide sleeve 143, so that the connecting frame 150 can move stably in the Z direction, thereby causing the loading mechanism 160 and the unloading mechanism 170 to move stably in the Z direction.

[0056] Further, refer to Figure 4 and Figure 6 The loading mechanism 160 includes an X-axis transfer assembly 161 and two clamping plates 162. The X-axis transfer assembly 161 is mounted on the connecting frame 150, and the two clamping plates 162 are symmetrically mounted on the X-axis transfer assembly 161. The X-axis transfer assembly 161 is used to drive the two clamping plates 162 toward or away from each other to clamp or release the filter element 10 to be trimmed. Specifically, the structure of the X-axis transfer assembly 161 is consistent with that of the first X-axis transfer mechanism 110. Therefore, the principle by which the X-axis transfer assembly 161 drives the two clamping plates 162 toward or away from each other is consistent with the principle by which the first X-axis transfer mechanism 110 drives the two first X-axis transfer plates 114 toward or away from each other.

[0057] Specifically, refer to Figure 4 and Figure 6 The structure of the unloading mechanism 170 is basically the same as that of the loading mechanism 160, or the unloading mechanism 170 uses a finger cylinder to drive the two clamping plates 162 to move closer to or away from each other.

[0058] Further, refer to Figure 4 The bracket 100 is provided with a drop hopper 180 below the filter element trimming mechanism 200, and a collecting box 190 is provided below the drop hopper 180. The excess right-angled edge strips 11 that have been cut off fall into the collecting box 190 through the drop hopper 180. The collecting box 190 is used to collect the excess right-angled edge strips 11 that have been cut off, and the excess right-angled edge strips 11 that have been cut off are centrally processed for easy processing.

[0059] The rest of this embodiment is the same as that of the first embodiment. The features not explained in this embodiment are all based on the explanations of the first embodiment and will not be described in detail here.

[0060] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, its architecture can be flexible and varied, and a series of products can be derived. Simply making a few simple deductions or substitutions should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
