Description

Technical Field

[0001] The present invention relates to the technical field of filter element processing equipment, and more specifically, to an air filter element edge strip shearing device. Background Art

[0002] Filter element is a professional term for filtering and purifying functions. It is mainly used in filtration industries such as oil filtration, air filtration, and water filtration. The filter element separates solid particles in liquid or gas, or allows different material components to fully contact. When the fluid enters the filter element with a filter screen of a certain specification, impurities are blocked, and clean fluid flows out through the filter element. The liquid filter element makes the contaminated liquid clean until it reaches the state required for production and life, that is, it makes the liquid reach a certain degree of cleanliness.

[0003] For example, utility model patent CN216422760U discloses a CNC device for cutting edge banding strips of automobile air conditioning filter elements, which performs stable unidirectional pulling and moving of edge banding strips. In the subsequent cutting process, multiple stable pullings are performed to stabilize the cutting quality. In the subsequent process, a clamping cylinder is used to prevent the edge banding strips from shaking and deflecting during the cutting process, so that the edge banding strips are pulled again to ensure stable cutting.

[0004] However, the above-mentioned patent document only has the function of pulling and guiding the filter element edge banding to be cut. In actual use, since there is no multi-channel cutting structure, only a single filter element edge banding cutting operation can be performed at a time, and it is impossible to directly control multiple cutters to cut the filter element edge banding at equal intervals, which affects the production rate of the filter element edge banding. At the same time, when cutting the filter element edge banding, it is also impossible to stably suppress and restrict it. The filter element edge banding is offset due to the pulling and squeezing of the cutter, that is, the cutting position of the filter element edge banding is affected.

[0005] In view of the above technical defects, a solution is now provided. Summary of the invention

[0028] Embodiment 1: Refer to the attached specification Figure 1-Figure 7 , an air filter element edge strip cutting device, such as Figure 1 and Figure 2 As shown, it comprises a base 1, a cutting table 2 is fixedly mounted on the top of the base 1, and a fixed-distance cutting mechanism 3 and a guide mechanism 4 are arranged on the top of the cutting table 2;

[0030] like Figure 3 and Figure 4 As shown, the outer walls of the multiple cutters 34 are respectively provided with clamping push plates 35, and the multiple clamping push plates 35 are arranged corresponding to the multiple cutters 34. A slide rail 36 is slidably installed on one side of the multiple clamping push plates 35. The clamping push plate 35 located in the middle is fixed to the outer wall of the slide rail 36. The clamping push plate 35 plays a role in limiting and determining the center, and prevents the multiple clamping push plates 35 on both sides from moving randomly.

[0031] The slide rail 36 is fixedly installed on the top of the cutting table 2, and a limited tension spring 37 is fixedly installed between any two adjacent clamping push plates 35. The limited tension spring 37 allows the multiple clamping push plates 35 to maintain a certain distance and pressure. When the multiple clamping push plates 35 are driven on the slide rail 36, the multiple clamping push plates 35 synchronously drive the multiple cutters 34 to move.

[0032] like Figure 3 and Figure 4 As shown, a pushing block 38 is provided between the tops of the plurality of pushing plates 35, the bottoms of the plurality of pushing blocks 38 are arranged in a sloped state, the outer walls of the plurality of pushing blocks 38 are fitted with the outer walls of the pushing plates 35, the plurality of pushing blocks 38 are arranged symmetrically in pairs, the plurality of pushing blocks 38 move downward synchronously, and then the plurality of pushing blocks 38 squeeze the plurality of pushing plates 35 respectively, and at this time the fixed position is maintained by the middle pushing plate 35, that is, starting from the middle pushing plate 35, the pushing blocks 38 on both sides squeeze toward both sides at the position of the middle pushing plate 35.

[0033] like Figure 3 and Figure 4 As shown, a pressure plate 39 is slidably installed on the top of multiple pushing blocks 38, and the pushing blocks 38 on both sides squeeze the clamping push plate 35 and slide synchronously on the bottom of the pressure plate 39, that is, the length between two adjacent clamping push plates 35 is the distance pushed by the pushing block 38 when it moves downward. The pressure plate 39 is slidably installed on the top of the slide rail 36, and the pressure plate 39 is set in a horizontal state. A threaded rod 310 is threadedly connected to one side of the pressure plate 39, and a rotating motor 311 is provided at the bottom of the threaded rod 310. The rotating motor 311 is fixedly installed on the top of the cutting table 2, and the threaded rod 310 is driven by the rotating motor 311 to make the pressure plate 39 move downward, and then the pressure plate 39 squeezes multiple pushing blocks 38 to move downward synchronously.

[0034] like Figure 2 and Figure 5 As shown, the guide mechanism 4 includes two limit plates 41 slidably mounted on the outer wall of one side of the cutting table 2. The two limit plates 41 are symmetrically arranged. The outer walls of the two limit plates 41 are fixedly mounted with limit springs 42. The limit springs 42 are fixedly mounted on the outer wall of the cutting table 2, and the two limit plates 41 can be close to each other through the limit springs 42.

[0035] like Figure 2 and Figure 5 As shown, a clamping plate 43 is fixedly installed on the top of the two limit plates 41, and the two clamping plates 43 are symmetrically arranged. The bottoms of the two clamping plates 43 are in contact with the top of the cutting table 2, and a guide plate 44 is fixedly installed on one side of the two clamping plates 43. The two guide plates 44 are arranged in an inclined state and are symmetrically arranged.

[0036] The two guide plates 44 are used to guide the large filter element edge sealing strips that are close to each other to the middle position, and then the large filter element edge sealing strips squeeze the two guide plates 44 so that the limit plate 41 compresses the limit spring 42 and slides, and the two clamping plates 43 are simultaneously unfolded to both sides and aligned with the two sides of the large filter element edge sealing strip. Then, the two clamping plates 43 clamp the two sides of the filter element edge sealing strip under the pressure of the limit spring 42 driven by the limit plate 41, that is, the center position of the filter element edge sealing strip is convenient for cutting to start from the middle alignment position.

[0037] In the specific implementation, the large filter element edge strips that are close to each other are first guided to the middle position by two guide plates 44, and then the large filter element edge strips squeeze the two guide plates 44 so that the limit plate 41 compresses the limit spring 42 and slides, and the two clamping plates 43 are simultaneously unfolded to both sides and aligned with the two sides of the large filter element edge strips, and then the two clamping plates 43 clamp the two sides of the filter element edge strips under the pressure of the limit spring 42 driven by the limit plate 41, that is, the center position of the filter element edge strip is convenient for cutting to start from the middle alignment position;

[0038] The servo motor 31 drives the rotating rod 32 and the plurality of limiting rods 33 to rotate synchronously, and then the plurality of cutters 34 are synchronously driven to rotate under the limit of the plurality of limiting rods 33, and then the rotating motor 311 drives the threaded rod 310 to move the pressing plate 39 downward, and then the pressing plate 39 squeezes the plurality of squeezing and pushing blocks 38 to move downward synchronously, and the plurality of squeezing and pushing blocks 38 move downward synchronously, and then the plurality of squeezing and pushing blocks 38 squeeze the plurality of clamping and pushing plates 35 respectively;

[0039] At this time, the middle push plate 35 is kept in a fixed position, that is, starting from the middle push plate 35, the pushing blocks 38 on both sides are squeezed toward both sides at the position of the middle push plate 35, and the push plates 35 are squeezed by the pushing blocks 38 on both sides and slide synchronously on the bottom of the pressure plate 39, that is, the length between two adjacent push plates 35 is the distance pushed by the pushing blocks 38 when they move downward, and the cutters 34 are controlled by the push plates 35 to maintain the same spacing, that is, multiple identical filter element edge banding strips can be cut and produced at the same time to facilitate increasing the production rate.

[0040] Embodiment 2: Figure 6 and Figure 7 As shown, a rolling mechanism 5 is provided between the multiple cutters 34, and the rolling mechanism 5 includes a joint plate 51 fixedly installed on the outer wall of the multiple clamping and pushing plates 35, and the multiple joint plates 51 are arranged in pairs corresponding to each other, and the tops of the two joint plates 51 are respectively hinged with a pull plate 52, and the two pull plates 52 are arranged obliquely upward, and the tops of the two pull plates 52 are commonly hinged with a supporting column 53, and the supporting column 53 is arranged in a vertical state. The number of the supporting columns 53 corresponds to the number of spacings between the multiple cutters 34;

[0041] The outer walls of the plurality of supporting columns 53 are fixedly installed with supporting springs 54, and the plurality of supporting springs 54 are fixedly installed on the outer wall of the connecting plate 51. The connecting plate 51 is driven to move synchronously by the movement of the plurality of clamping and pushing plates 35, that is, the plurality of connecting plates 51 drive the pull plate 52 and the supporting columns 53 under the support of the supporting springs 54, so that the supporting columns 53 are always located at the center position among the plurality of clamping and pushing plates 35.

[0042] like Figure 6 and Figure 7 As shown, the outer walls of the plurality of supporting columns 53 are sleeved with push racks 55, and pressure rollers 56 are rotatably installed at the bottoms of the plurality of push racks 55. The plurality of pressure rollers 56 are vertically downwardly arranged, and weight blocks 57 are fixedly installed on the tops of the plurality of push racks 55, that is, the push racks 55 on the outer walls of the supporting columns 53 drive the pressure rollers 56 to be located at the center positions of the plurality of clamping push plates 35 under the pressure of the weight blocks 57, so that the plurality of pressure rollers 56 squeeze the tops of the filter element edge sealing strips respectively, and the center positions of the cut positions on both sides of the filter element edge sealing strips are subjected to continuous pressure, so that the filter element edge sealing strips remain stable, and the filter element edge sealing strips are prevented from being offset and affecting the cutting position.

[0043] In the specific implementation, the movement of multiple clamping and pushing plates 35 drives the connecting plates 51 to move synchronously, that is, the multiple connecting plates 51 drive the pulling plates 52 and the supporting columns 53 under the support of the supporting springs 54, so that the supporting columns 53 are always located at the center position among the multiple clamping and pushing plates 35, that is, the pushing frame 55 on the outer wall of the supporting columns 53 drives the pressure roller 56 to be located at the center position of the multiple clamping and pushing plates 35 under the pressure of the weight block 57, so that the multiple pressure rollers 56 squeeze the top of the filter element edge banding strips respectively, and the center positions of the cut positions on both sides of the filter element edge banding strips are subjected to continuous pressure, so that the filter element edge banding strips remain stable, and the filter element edge banding strips are prevented from being offset and affecting the cutting position.
